I. WASHING MACHINE

A clothes machine and a method of controlling it, as established and widely described, will be described in reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a washing machine according to a first embodiment so widely described here, from which control methods according to various embodiments can be

3/104 applied.

Referring to FIG. 1, a laundry machine 100 according to a first embodiment includes a cabinet 110 configured to define an exterior appearance thereof, a bowl 120 provided in cabinet 110 to hold the washing water in it and a rotating drum 130 provided in the bowl 120. Cabinet 110 defines the outer appearance of the washing machine 100. Door 113 is provided in an opening 114 of cabinet 110 and a user opens door 113 to place the laundry in cabinet 110.

Bowl 120 is provided in cabinet 110 to retain washing water in it. 10 Drum 130 can be rotatable in bowl 120 and can accommodate laundry in it.

In this case, a plurality of elevators 135 can be provided on the drum 130 to lift and release the laundry during washing. The drum 130 includes a plurality of through holes 131 to allow the washing water held in the bowl 120 to pass through them. Bowl 120 can be supported by one or more springs provided on the outside of bowl 120. A motor 140 is mounted on a rear surface of bowl 120 and motor 140 rotates drum 130. When vibration is generated by the drum 130 rotated by the motor 140, the bowl 120 is vibrated in communication with the drum 130. When the drum 130 is rotated the vibration generated in the drum 130b and the bowl 120 can be absorbed by a damper located under the bowl 120.

As shown in FIG. 1, bowl 120 and drum 130 can be supplied substantially in parallel with a base plate of cabinet 110. Alternatively, rear portions of bowl 120 and drum 130 can be positioned in an oblique orientation, with the open end of the drum 25 130 oriented slightly upward to facilitate the loading of laundry onto drum 130.

More details of the washing machine

4/104 are described in Patent No. US 6460382 B1 filed on October 8, 2002 and in application No. US 12/704, 923 filed on February 12, 2010, the total disclosures of which are incorporated by reference in this document.

Fig. 2 is an exploded perspective view of a washing machine according to another example as presented here and widely described; A washing machine according to different modalities, as widely described here, may include a tub fixedly supported on a cabinet, or a tub supported on a cabinet through a flexible structure, such as a suspension unit, and therefore not fixedly attached to the themselves, as shown in FIG. 2. In addition, the support structure of the bowl can be between the support through the suspension unit and complete fixation structure. That is, the bowl can be supported flexibly through a suspension unit that will be described later, it can be fixedly supported in a more rigidly supported state than the flexible state supported above. In alternative modes, the washing machine can be supplied without a cabinet. For example, an installation space for a built-in washing machine can be defined by a wall structure instead of a cabinet. That is, in certain embodiments, a cabinet configured to form an independent exterior appearance may not be provided.

Referring to FIG. 2, the bowl may include a front bowl 200 and a rear bowl 220 that make up a rear portion of the front bowl 200. The front of bowl 200 and the rear of bowl 220 can be mounted by screws or other suitable securing mechanism, and a predetermined space is formed to accommodate a drum. The rear bowl 220 includes an opening formed on a rear surface thereof and a rear gasket 250 can be connected to an internal circumference of the opening. The rear gasket 250 can be connected to the rear of the bowl 230 and the rear of the bowl 230 can include a through hole with an axis that passes through its center.

The rear gasket 250 is sealed and connected to the rear of the bowl 230 and the rear of the bowl 220 to prevent wash water from leaking out of the bowl. As the rear bowl 230 vibrates when the drum is rotated, the rear of the bowl 230 may be distant from the rear of the bowl 220 at a predetermined distance so as not to interfere with the rear bowl 220. In addition, the rear joint 250 may be formed flexible material to allow the rear of the bowl 230 to move relatively, not interfering with the rear of the bowl 220. The rear joint 250 may include a corrugated part, which is extensible to a sufficient length

5/104 to allow relative movement of the rear of the bowl 230. This embodiment has the rear joint 250 connected to the rear of the bowl 230 and the present invention is not limited to them. The rear gasket 250 is configured to seal the space between the bowl and a driving part (not shown), including an axle 351 and a housing 400 to allow the driving part to move relatively relative to the bowl. As a result, the shapes and the connected objects of the rear joint 250 can be variable unlimited, only if this function is activated. A flexible material 280 that will be described as the front gasket later can be installed in a front part of the front tank 10 200.

The drum can be configured from a front of the drum 300, a center of the drum 320 and a rear of the drum 340. Ball balancers 310 and 330 can be installed in the front and rear portions of the drum, respectively. The back of the drum 340 can be connected to a spider 350 and the spider 350 can be connected to the axis 351. The drum is rotatable inside the bowl by a rotational force transmitted through the axis 351.

The 351 axis can be connected to a motor and pass through the rear of the bowl 230. In certain embodiments, the motor can be connected to the 351 axis concentrically. In certain embodiments, the motor 20 can be connected directly to shaft 351, and in particular, a motor rotor can be connected directly to shaft 351. In alternative embodiments, the motor and shaft 351 can be indirectly linked to each other, for example. example, they can be connected by a belt.

The housing 400 can be attached to the rear of the bowl 230 25 rotatably to support the shaft, between the motor and the rear of the bowl 230. A stator can be fixedly attached to the housing 400. And the rotor can be located in around the stator. As mentioned above, the rotor can be connected directly to the 351 shaft, with the motor being an external rotor type motor that can be connected directly to the shaft. The housing 400 400 can be supported by a base 600 through the suspension unit. The suspension unit may include a perpendicular suspension and an oblique suspension configured to support the bearing housing 400 with respect to a forward and backward direction. For example, the suspension unit according to this embodiment can include three perpendicular suspensions 35 (vertical, as shown in Figure 2) 500, 510 and 520 and two oblique suspensions (angled, or inclined, as shown in Figure 2) 450 and 530

6/104 configured to support the bearing housing 400 with respect to a forward and backward direction. The suspension unit can be connected to the base 600 with a predetermined elastic transformation allowing for forward / backward and / or right / left movement of the drum, and therefore is not fixedly connected. That is, the suspension unit can be supported by the base, with sufficient pre-determined elasticity to allow rotation at a predetermined angle in forward / backward and right / left directions with respect to the points connected with the base. For such support the elastic, the perpendicular suspension can be installed on the base by a rubber bushing or other mechanism, as appropriate.

The perpendicular suspension of the suspension unit may suspend the drum vibration elastically and the oblique suspension may dampen the vibration. That is, the perpendicular suspension can be used as a spring and the oblique suspension as a means of damping in a vibration system including a spring and damping means.

The tub is supported on the cabinet and the vibration of the drum can be attenuated by the suspension unit. As a result, the washing machine according to this modality may have a substantially independent support structure between the bowl and the drum or it may have a structure with the vibration of the drum not directly transmitted to the bowl.

II DRUM ROTATION MOVEMENT

The diversification of drum driving movements and their combinations, consecrated and widely described, can provide significant improvements in washing capacity, noise / vibration, energy consumption and customer satisfaction. A control method that offers better washing capacity will be described. The hand wash effect can be incorporated by several standard movements of the laundry. For example, the hand wash effect can be incorporated by a combination of massage and / or untangling and / or tapping and / or oscillation and / or friction and / or compression / filtration.

Such patterns of varying movements of clothing can be implemented by various drum driving movements and combination (s) of different drum driving movements. Drum driving movements may include combinations of directions of rotation and speeds of rotation. Clothes located on the drum may have different trim directions, trim points and trim distance because of the driving motion of the drum.

7/104 drum. Because of this, the clothing may have a different movement inside the drum. The driving movements of the drum can be incorporated, for example, by controlling the direction of rotation and / or speed of the motor that drives the drum.

When the drum is rotated, the laundry is lifted by one or more elevators 135 provided on the inner circumferential surface of the drum. Because of this, the direction of rotation of the drum can be controlled and the shock applied to the laundry can vary accordingly. That is, a mechanical force applied to clothing, such as the friction generated between items of clothing, the friction generated between clothing and water, and the shock of falling clothing can be varied. In other words, a degree of tapping or rubbing applied to items of clothing in order to wash clothes can be varied and a degree of distribution of clothing or turning inside the drum can be changed accordingly.

As a result, this washing machine control method can provide several drum driving movements and the drum driving movements are varied according to each cycle and a specific step that makes up the cycle, such that a force Ideal mechanics can be used to treat the laundry, depending on the type of laundry to be washed, the ground level and other factors. Because of this, the efficiency of laundry washing can be improved. In addition, the excessive time required by the typical drum driving motion can be avoided.

In certain embodiments, to incorporate such varied movements of driving the drum, the motor 140 may be of a direct connection type. That is, the motor may have a stator fixed to a rear surface of the bowl 120 and a rotor that rotates the drum 120 directly. Since the direction of rotation and torque of the direct connection type motor can be controlled, the time delay or retraction can be prevented and then the driving motion of the drum can be controlled as appropriate.

In contrast, the driving movements of the drum allowing delay or retraction, for example, an oscillating or rotating movement, can be incorporated into an engine with an indirect type connection including a pulley such that its torque can be transmitted to a shaft through the pulley. However, the motor with an indirect type connection may have limited applicability.

The driving motion of the drum can be incorporated by motor control 140. As a result, the method of driving the motor can be diversified, and then the various driving movements of the drum can be

8/104 be achieved.

Patterns of movement of clothing and the movement of driving the drum to achieve the pattern of movement of clothing will be described in detail below.

A pattern of massage movement of the laundry can be achieved if the friction between the laundry and the drum is maximized. For example, when the drum is rotated continuously in a predetermined direction at a predetermined speed or less, the laundry can be moved by rolling to achieve the massage effect. If the rotation speed of the drum driven in the oscillating motion is defined as a reference speed, the predetermined speed can be the reference speed. For example, a driving motion of the drum configured to rotate the drum at a predetermined speed or less in a predetermined direction can be defined as rolling motion.

A pattern of movement to untangle can be incorporated, for example, by a movement in a fall. The oscillating movement can be defined as a continuous movement configured to rotate the drum at the reference speed in a predetermined direction. The pattern of movement for untangling allows the clothes to fall into the drum, with a medium drop distance and medium friction.

A pattern of tapping motion can be achieved by dropping the laundry inside the drum from a maximum fall distance. For example, if the drum is rotated at the reference speed or more to lift the laundry to the highest point inside the drum, and then the drum is stopped suddenly, such a knocking effect can be achieved. This movement of driving the drum can be defined as step movement.

A pattern of oscillating motion can be achieved when the drum is rotated at a predetermined speed less than the reference speed in a clockwise / counterclockwise direction. Such driving motion of the drum can be defined as oscillating motion.

A pattern of rubbing motion can be achieved when the friction between the laundry and the drum is increased. For example, if the drum rotating at the reference speed or more clockwise is suddenly stopped and then rotated counterclockwise, the laundry is being moved by rolling along the inner circumferential surface of the drum from a point predetermined drum height. Such movement of driving the

9/104 drum can be defined as rubbing motion.

A pattern of compression and filtration movement can be achieved if washing water is supplied by rotating the drum at the reference speed or more. Once the drum is rotated at a relatively high speed, the laundry can unfold, or spread and hang along the inner circumferential surface of the drum, and then the washing water released into the drum passes through the laundry, in Then the laundry can be squeezed to improve the washing effect. Such a drum driving movement can be defined as a filtration movement.

The varied driving movements of the drum configured to achieve the various movement patterns of the above clothing will be described with reference to the drawings.

FIG. 3 is a diagram of various drum drive movements as incorporated and widely described here.

FIG. 3 (a) is a diagram of a rolling motion. In the rolling motion, the motor 140 continuously rotates the drum 130 in a predetermined direction and the laundry to be washed located on the inner circumferential surface of the drum rotating along the direction of rotation of the drum is dropped from position at an angle of approximately less than 90 ° with respect to the drum rotating drum to the lowest point of the drum.

That is, since the motor 140 spins the drum at a speed that is less than the reference rotational speed (fall speed), for example, at about 40 RPM, the laundry located at the lowest point of the drum 130 is raised to a predetermined height along the direction of rotation of drum 130, and then the laundry moves by rolling to the lowest point of the drum from the position of less than 90 ° with respect to the direction of rotation of the drum from the lowest point of the drum. Visually, in the event that the drum is turned clockwise, the laundry is continuously rolled in a third quadrant of the drum.

The laundry is washed by the maximum friction with washing water and the maximum friction with other washing items and the maximum friction with the inner circumferential surface of the drum in rolling motion. This scrolling movement allows sufficient return of the laundry to generate a gentle massage-like washing effect. The drum RPM of the drum driving movement can be determined based on a drum radius ratio. That is, the higher the drum RPM, the greater the force

10/104 centrifuge that is generated in the laundry inside the drum. The difference between the size of the centrifugal force and the gravity force applied to the washing items in the drum differentiates the point at which the laundry is dropped and the corresponding movement of the laundry inside the drum. Both the rotational force of the drum and the friction between the drum and the laundry can also be considered. Thus, the RPM of the drum in the rolling motion can be determined to allow the centrifugal force generated and the frictional force to be less than gravity (1G).

Fig. 3A (b) is a diagram of an oscillating movement. In the rotating motion, the motor 140 continuously rotates the drum 130 in a predetermined direction and the washing laundry located on the inner circumferential surface of the drum is removed from its position at an angle of approximately less than 90 ° to 110 ° in relation to the direction of rotation from the rotation drum to the lowest point of the drum. If the drum is controlled to be rotated with the proper RPM in a predetermined direction, mechanical force can be generated between the laundry and the drum in the rotating motion. Because of this, the rotating motion can be used for washing and rinsing.

That is, the laundry loaded on drum 130 is located at the lowest point of drum 130 before motor 140 is started. When the motor 140 provides a torque for the drum 130, the drum 130 is rotated and the lifter 135 provided on the inner circumferential surface of the drum raises the laundry at a predetermined height from the lowest point of the drum. If the motor 140 spins the drum 130 at the reference speed of rotation, for example, about 46 RPM, the laundry can be lifted to the position of approximately 90 ° to 110 ° with respect to the direction of rotation of the drum, and then , tipped to the lowest point of the drum. In rotating motion, the RPM of the drum can be determined to allow the centrifugal force generated to be greater than the centrifugal force generated in the rolling motion and to be less than gravity.

Visually, if the drum is rotated clockwise in a rotating motion, the laundry is sequentially raised to the third quadrant and part of a second quadrant from the lowest point of the drum. After that, the laundry is dropped at the lowest point of the drum. As a result, the rotating movement allows the laundry to be washed by the shock generated by the friction with the washing water and the shock of the fall. Because of this, in the rotating movement, a mechanical force greater than the mechanical force of the rolling movement

11/104 can be used to implement washing and rinsing. In addition, the scrolling motion can be effective in separating tangled clothing and uniform distribution of clothing.

Fig. 3A (c) is a diagram of a step movement. In step motion, the motor 140 continuously rotates the drum 130 in a predetermined direction and the laundry located on the inner circumferential surface of the drum is controlled to be dropped at the deepest point of the drum from the highest position of the drum (approximately 180 °) in the direction of rotation of the drum. Since the motor 140 rotates the drum 130 at a speed that is greater than the reference rotational speed (rotating speed of rotation), for example, at about 60 RPM or more, the laundry can be rotated by centrifugal force until it reaches the highest point of the drum, without being knocked over. In step motion, the drum is spun at a predetermined speed so as not to drop the laundry, and then it is suddenly stopped to maximize the shock applied to the laundry as it is dropped.

After turning the drum 130 at the predetermined speed capable of not dropping the laundry (about 60 RPM or more), until the laundry reaches almost the highest point of the drum, motor 140 provides reverse torque to the drum 130 with the laundry close to the highest point of the drum (180 ° with respect to the direction of rotation of the drum). Thus, the laundry is lifted from the lowest point of the drum 130 along the direction of rotation of the drum, the drum is stopped momentarily by the reverse torque of the motor, and the laundry is dropped from the highest point to the lowest point of the drum 130. The step movement allows the laundry to be washed by the shock generated while the laundry is dropped with the maximum height difference. The mechanical force generated in this step movement is greater than the mechanical force generated in the rolling or rotating movement mentioned above.

Visually, in step motion, after moving from the lowest point to the highest point of the drum as the drum is rotated, the fall distance within the drum is the largest in the step movement, and the mechanical force of the step movement can be applied to a small amount of clothing effectively. The motor 140 can be braked with phase inversion in the movement by step using a torque generated in a reverse direction in relation to a direction of rotation of the motor. One phase of a current supplied to the motor can be inverted to generate reverse torque in a reverse direction of rotation of the motor and reverse phase braking allows the sudden stop to be applied.

10/124

The reverse phase brake can be used to apply a strong shock to clothing.

Thus, after applying torque to turn the drum clockwise, the torque is applied to turn the drum counterclockwise and the drum is stopped suddenly. After that, a torque is applied to the drum to rotate clockwise and the movement per step is incorporated. The step movement can be used to wash the laundry using the friction between the water extracted through the through hole 131 formed in the drum and the laundry using the shock generated by the laundry falling when the laundry reaches the highest point of the drum. This step-by-step movement can generate a wash-type effect.

Fig. 3A (d) is a diagram of an oscillating movement. In the oscillating movement, the motor 140 rotates the drum 130 clockwise and counterclockwise, and alternatively the laundry falls in a position of less than 90 ° with respect to the direction of rotation of the drum. That is, since motor 140 spins drum 130 at a speed that is less than the reference rotational speed (rotating rotational speed), for example, at about 40 RPM counterclockwise, the laundry located at the lowest point of the drum 130 it is raised to a predetermined height along the counterclockwise direction. Before the laundry reaches the position at about 90 ° with respect to the counterclockwise direction of the drum, the motor stops the rotation of the drum and the laundry is dropped to the lowest point of the drum in the position at about less than 90 ° with respect counterclockwise of the drum.

Thus, motor 140 rotates drum 130 at a speed that is less than the reference rotational speed (rotating speed of rotation), for example, at about 40 RPM clockwise to raise the laundry to a predetermined height clockwise along the direction of rotation of the drum. Before the laundry reaches the position at about 90 ° with respect to the counterclockwise direction of the drum, the motor stops the rotation of the drum and the laundry is dropped to the lowest point of the drum in the position at less than 90 ° with respect to the clockwise direction of the drum.

Thus, the oscillating movement is a movement in which the rotation and stop with respect to a first direction, and the rotation and stop with respect to a second (opposite) direction can be repeated. Visually, clothing that is lifted until a part of the second quadrant from the third quadrant of the drum falls smoothly, and is re-lifted to a part of the first quadrant from a fourth quadrant of the drum and falls gently, several times.

10/13

In certain embodiments, motor 140 can use dynamic braking and a load applied to motor 140 so that mechanical wear on motor 140 can be reduced, and the shock applied to clothing can be adjusted. Using rheostatic braking, if a current applied to the motor is switched off, the motor functions as a generator because of the rotation inertia, and a direction of a current flowing in a motor coil will be turned in a reverse direction before the energy is turned off. off and a force (Fleming's right hand rule) is applied along a direction that interferes with the engine rotation, to brake the engine. Unlike reverse phase braking, rheostatic braking does not generate sudden braking, but changes the direction of rotation of the drum smoothly. As a result, the laundry can be moved in the shape of 8 along the third and fourth quadrants of the drum in the oscillating motion. The oscillating movement can generate washing of the oscillating type.

Fig. 3A (e) is a diagram of a rubbing motion. In the rubbing motion, the motor 140 rotates the drum 130 in both clockwise and counterclockwise alternatively and the laundry can be dropped from a position of about 90 ° with respect to the direction of rotation of the drum.

That is, since motor 140 spins drum 130 at a speed that is greater than the reference rotational speed (rotating rotational speed), for example, at about 60 RPM or more counterclockwise, the laundry located at the lowest point of drum 130 is raised to a predetermined height counterclockwise. After the laundry passes through a position at approximately 90 ° with respect to the counterclockwise direction of the drum, the motor provides the drum with an inverse torque to temporarily stop the drum and the laundry located on the inner circumferential surface of the drum can be dropped quickly. In particular, the laundry located on the inner circumferential surface of the drum is moved to the lowest point of the drum at a position of 90 or more with respect to the clockwise direction of the drum. Thus, the laundry can be dropped quickly from the pre-determined height, in the rubbing motion. Motor 140 can use reverse phase braking to brake the drum.

In the rubbing movement, the direction of rotation of the drum is changed quickly and the laundry may not be removed from the inner circumferential surface of the drum for a large amount of time. Therefore, a strong scrubbing wash effect maximizing the friction between the laundry and the drum can

14/104 be achieved in the scrubbing movement. In the scrubbing motion, clothing that has moved to a part of the second quadrant through the third quadrant is dropped quickly and is re-dropped after being transferred again to a part of the first quadrant through the fourth quadrant. As a result, visually in the rubbing motion, the raised laundry falls along the inner circumferential surface of the drum repeatedly.

FIG. 3 (f) is a diagram of the filtering movement. In the filtering movement, the motor 140 rotates the drum 130 so that the laundry to be washed is not dropped from the inner circumferential surface of the drum, and the washing water is sprayed onto the drum. That is, in the filtering movement, the laundry to be washed is distributed and maintains close contact with the inner circumferential surface of the drum as the washing water is sprayed on the drum. Water is discharged from the bowl through through holes 131 of the drum by centrifugal force. Since the filtering movement spreads / widens a surface area of the laundry to be washed and allows water to pass through the laundry to be washed, the washing water can be supplied to the laundry to be washed evenly.

FIG. 3 (g) is a diagram of the compression movement. In the compression movement, the motor 140 rotates the drum 130 so that the laundry to be washed sticks to / is not dropped from the inner circumferential surface of the drum using centrifugal force, and then the motor reduces the rotation speed of the drum 130 to temporarily separate the laundry to be washed from the inner circumferential surface of the drum. This process is repeated and the water is sprayed onto the drum during drum rotation. That is, the drum is rotated continuously at a speed that is high enough not to drop the laundry to be washed from the inner circumferential surface of the drum in the filtering movement. In contrast, in the compression movement, the rotation speed of the drum is changed to repeat the process of the laundry to be washed by sticking to and separating from the inner circumferential surface of the drum 130.

The launching of washing water into drum 130 in the filtration movement and the compression movement can be implemented, for example, by a circulation route and a pump. The pump can communicate with the bottom surface of the tub 120, with one end of the circulation path connected to the pump in such a way that the wash water is released from the tub into the drum through the other end of the circulation path.

In alternative modalities, washing water can be sprayed to

15/104 inside the drum through a supply path connected with an external water supply located outside the cabinet. That is, one end of the supply route is connected to the external power supply and the other end of it is related to the tank. If a nozzle is provided to deliver washing water to the drum, the washing water can be sprayed onto the drum in either or both of the filtration and compression movements.

Fig. 4 is a diagram of the movement per step in detail.

First of all, the laundry is moved from a lower point to a higher point of the drum 130, as shown in FIG. 4 (a) - (c). As described in relation to the bowl 120 being vertical beside the drum 130, the laundry received in the drum 130 is moved from a position adjacent to the lowest point of the bowl 120 to the highest point of the bowl 120. For such movement of the laundry, the motor 140 applies a rotating force, that is, torque to the drum in a predetermined direction, which is clockwise, as shown in the drawings, and drum 130 is rotated along the predetermined direction together with the clothes, to lift the clothes.

The laundry can be rotated together with the drum, in close contact with an internal surface of the drum 130 by a frictional force with lifters and the circumferential inner surface of the drum 130. The laundry is raised to the highest point of the drum 130, without being separated from drum 130 by rotating drum 130 at approximately 60 RPM or more, as this rotation speed generates a predetermined centrifugal force sufficient to prevent the laundry from separating from drum 130 to the highest point of drum 130 .

The rotation speed of the drum can be changed so that the generated centrifugal force is greater than gravity, allowing the laundry to be rotated together with the drum at the lowest point of the 130 drum, which is a predetermined point on the surface the drum next to the lowest point of the bowl 120 to the highest point of the bowl20. The laundry is removed from the highest point of the drum 130 to the lowest point of the drum 130 when the drum 130 is suddenly braked, either during or just before the laundry reaches the highest point of the drum 130.

Specifically, to suddenly brake drum 130, motor 140 supplies drum 130 with reverse torque. The reverse torque is generated by the braking phase inversion configured to provide inverted phase currents for the

16/104 motor 140, as described with reference to FIG. 3A (c). Reverse phase braking is a type of motor braking using torque generated in a reverse direction relative to a direction of rotation of the motor. One phase of a current supplied to the motor can be reversed to generate reverse torque in a reverse direction of rotation of the motor and reverse phase braking allows the brake to be applied suddenly to the motor. For example, as shown in the drawing, a chain is applied to the motor to turn the drum clockwise, and then a chain is applied to the motor to turn the drum counterclockwise suddenly.

The time point of reverse phase braking with respect to the motor 140 may be closely related to the location of the laundry inside the drum 130. Because of this, a device used to determine or predict the location of the laundry can be provided and a device such as a Hall effect sensor configured to determine a rotor rotation angle, can be examples of such a device. The control piece can determine the rotation angle of the drum, using the motor detection and control device 140 for reverse phase brake when or just before the drum has a 180 ° rotation angle. As a result, the rotation of the drum clockwise is stopped quickly in response to torque counterclockwise. The centrifugal force applied to the garment is removed and the garment is then dropped at the lowest point.

Thus, as shown in FIG. 4 (d), drum 130 is continuously rotated clockwise and the rotation / drop of the laundry is repeated. Although FIG. 4 show that the drum is rotated clockwise, the drum can be rotated counterclockwise to implement step movement. The movement per step generates a relatively large load on the motor 140 and a net rate of activation of the movement per step can be reduced.

The net start rate is a ratio of an engine start time to a total driving time and engine stop time value 140. If the net start rate is 1, it means that the engine starts without a stop time. The movement per step can be implemented in approximately 70% of the net activation rate, considering the motor load. For example, the engine can be stopped for 3 seconds after running for 10 seconds. Other operating / stopping times and reasons may also be appropriate.

Before the clothes that fall reach the lowest point of the drum, that is,

17/104 while the garment is dropped, drum 130 begins its rotation to implement the next step movement. In this case, the drum 130 is rotated at a predetermined angle and after that the laundry reaches the lowest point of the drum 130. From this point, the laundry and the drum can be rotated together. Although the drum is rotated 180 ° as defined, the laundry cannot be rotated 180 °, that is, the highest point of drum 130 and cannot be dropped from the highest point to gain a. desired washing capacity.

Therefore, drum 130 is controlled to be rotated again as shown in FIG. 4 (d) after the laundry reaches the lowest point of the drum. That is, the drum remains in a stationary position until the laundry reaches the lowest point of the drum. More specifically, the moment the laundry actually starts to be dropped, the drum stop 130 is generated. From the point of falling time to the point where the laundry reaches the lowest point of the drum, the drum remains stationary and does not turn. The downtime can be longer than the time needed for the laundry to be dropped to the lowest point (point 1) from the highest point on the drum. As a result, the drum can remain stationary for, for example, 0.4 seconds, or in certain embodiments, 0.6 seconds, to ensure sufficient time in the stopped state. This allows the movement by step to be implemented more precisely to generate maximum shock and the desired washing capacity can be achieved accordingly.

Fig. 5 is a diagram of the rubbing movement in detail.

First, the laundry is moved from the lowest point of the drum 130 to the position reached after rotating 90 ° or more in the clockwise direction of the drum 130, as shown in Figs. 5 (a) - (c). As described in relation to the bowl 120 remaining vertical to the drum 130, the laundry inside the drum 130 is moved from the predetermined point of the inner surface of the drum adjacent to the lowest point of the bowl 120 to the point of the rotated inner drum surface 90 ° or more along the clockwise direction of drum 120. To generate such movement of the laundry, the motor applies a rotating force, that is, torque to drum 130 in a predetermined direction, which is clockwise , and drum 130 is rotated along the predetermined direction in conjunction with the laundry to lift the laundry.

The laundry is rotated together with the drum, in close contact with an internal circumferential surface of the drum 130 by the lifter and the frictional force with the circumferential internal surface of the drum, and is not separated from the drum

10/184

130. To do this, the drum is rotated at about 60 rpm or more to generate sufficient centrifugal force so that the laundry is not separated from the drum 130. The rotation speed of the drum can be configured to generate a centrifugal force greater than that gravity, taking the size of the drum, as well as an internal diameter, into account. As a result, the laundry is rotated together with the drum from the lowest point of the drum to the position of 90 ° or more of rotation with respect to the lowest point of the drum.

The laundry is then removed from the position at 90 ° or more of rotation to the lowest point. For this laundry fall, the drum 130 is braked suddenly, when the laundry reaches the position of 90 ° or more of rotation of the drum. Motor 140 provides drum 130 with reverse torque to apply sudden drum braking. As mentioned above, with reference to FIG. 3A (e) the reverse torque is generated by the braking phase inversion configured to supply inverted phase currents for the motor 140.

The control piece can determine a drum rotation angle, using a sensor device, as described above. Since the drum rotation angle is 90 ° or more, the control piece can control the motor 140 to be in the inverted phase braking. As a result, drum 130 rotating clockwise is provided with torque counterclockwise to momentarily stop rotation and remove the centrifugal force applied to the garment. As shown in FIG. 5 (c), the laundry cannot be dropped perpendicularly by counterclockwise torque, but falls to the lowest point of the drum obliquely towards the circumferential inner surface of the drum. Because of the sloping fall, the laundry can have a relatively large amount of friction with the inner surface of the drum in the middle of the fall and the simultaneous friction between the laundry items and between the laundry and the washing water can be relatively large.

Thus, as shown in FIG. 5 (d), the drum is rotated 130 counterclockwise and rotating continuously and the rotation / dropping of the aforementioned laundry can be repeated. FIG. 5 shows that the drum is rotated clockwise earlier, but counterclockwise rotation can be implemented earlier. The scrubbing motion generates a relatively large load applied to the motor 140, such as the step motion, and the net drive rate can be reduced, for example, stopping for 3 seconds after the scrubbing motion can be repeated and the net rate of The wiping movement can be controlled to be 70%. Other modalities also

19/104 may be appropriate.

Before the falling clothing reaches the lowest point of the drum, that is, while the clothing is dropped, the drum 130 begins its rotation in the reverse phase to implement the next step movement. In this case, the drum 130 and 5 rotated at a predetermined angle and after that the laundry reaches the lowest point of the drum 130. From this point, the laundry and the drum can be rotated together. Although the drum is rotated 90 ° as defined, the laundry cannot be turned by 90 ", that is, the highest point of drum 130 and cannot be dropped from the highest point to gain the desired washing capacity.

_{10 by} J are _O, the drum 130 is controlled to be further rotated as shown in FIG. 5 (d) after the laundry reaches the lowest point on the drum. In other words, the drum is controlled to remain in a stopped position until the laundry reaches the lowest point of the drum. More specifically, the moment the laundry actually begins to be dropped, the drum stop 130 is generated. From the point of drop in the time the laundry falls to the point where the laundry reaches the lowest point of the drum, the drum remains in a stopped state and does not rotate. The downtime can be longer than the time needed for the laundry to be dropped to the lowest point on the drum. As a result, the idle state maintained by the drum can be defined as, for example, 0.2 seconds, which is less than the idle state of the drum in step motion.

As such, the stopped state maintained by the drum is defined, the movement per step can be implemented more precisely, in order to generate the maximum friction between the inner surface of the drum and the laundry, maximum friction between the 25 items to be washings and maximum friction between the laundry and the washing water and the desired washing capacity can be obtained accordingly.

Fig 6 is a graph that compares the washing capacity and vibration level of each movement shown in FIG. 3A. A horizontal axis has the capacity to wash clothes, with easier separation of 30 contaminants contained in the clothes moving to the left. A vertical axis shows the level of vibration or noise, with higher levels moving upwards, with washing time for the same laundry being reduced.

The movement per step and the scrubbing movement are suitable for washing courses implemented to reduce the washing time, when the laundry has serious contaminants. Step motion and scrubbing motion have a high level of vibration / noise and are not normally used

20/104 for washing sensitive fabrics and / or to minimize noise and vibration.

The rolling motion has a good washing capacity and a low level of vibration, with minimized damage to clothes and low engine load. As a result, the scrolling motion can be used in all washing strokes, especially to facilitate the dissolution of detergent in an initial wash phase and to wet clothes.

The rotating movement has a washing capacity less than the rubbing movement and a medium level of vibration compared to the rubbing movement and the rolling movement. The rolling motion has a lower vibration level, but has a longer washing time than the rotating motion. Because of this, the rotating motion can be applied to all wash strokes and can be effective on one wash streak to distribute laundry evenly.

The compression grip has a washing capacity similar to the rotating motion and a higher vibration level than the rotating motion. The compression movement repeats the process of placing the laundry towards and separating the circumferential inner surface of the drum. In this process, the washing water is discharged out of the drum after passing through the laundry. Thus, the compression movement can be applied to washing.

The filtration movement has a lower washing capacity than the compression movement and a noise level similar to the scroll movement. In the filtration movement, water passes through the laundry and is discharged out of the drum, with the laundry in contact with the circumferential inner surface of the drum. As a result, the filtration movement can be applied to a stroke to wet the laundry.

The oscillating movement has the lowest vibration level and the ability to wash and can be applied in progress with a low noise level and a low vibration wash stroke and a stroke to wash sensitive or delicate items.

As mentioned above, each drum drive movement has its own advantages and it is preferable that the various driving movements of the drums are used to maximize the advantages. Each drum driving movement can also have advantages and disadvantages in relation to the amount of laundry. Even in the case of the same stroke and cycle, the various driving movements can be applied differently depending on the relationship with the amount of clothing.

10/214

An interior of the drum in the drum-type washing machine can be visible from the outside through the door. The various driving movements of the drum can be implemented in a washing course that will be described later. As a result, the user can view the various drum driving movements implemented inside the drum. That is, a type of wash with gentle strokes (rotating movement), a type of strong stroke wash (movement by step), type of gentle scrubbing washing (rolling motion) and a type of strong scrubbing washing (movement of step) rubbing) can be visibly identified. Because of this, the user can perceive that the washing is well applied, which can generate greater user satisfaction, in addition to the substantially improved efficiency of washing clothes.

III. WASHING MACHINE COURSES

Different control methods, that is, several washing machine courses that are well-known and widely described here, will now be discussed.

A. COURSE A (STANDARD COURSE)

Course A will be described with reference to FIG. 7. Course A is a standard course that can be used to wash normal clothes without any auxiliary options. Course A includes a wash cycle, a rinse cycle and a spin cycle. The user can select the normal stroke from a selection piece 117 (S710).

A.1 washing cycle (S730):

The wash cycle includes a water supply step (S733) that supplies washing water and detergent to a tub 120 or a drum 130 to dissolve the detergent in the wash water, and a wash step (S742) configured to trigger the drum for washing clothes. In the water supply step, water is supplied from an external water supply source to the washing machine, along with the detergent. By improving the efficiency of the water supply step in preparation for the washing step, the efficiency of the washing cycle, including washing efficiency and reduced washing time can also be achieved.

A.1.1 Determining the amount of clothing (S731):

As mentioned above, the water supply step is done in preparation for the main wash step. As a result, dissolving detergent, wetting clothes and the like can be implemented quickly and completely. However, considering the capacity of the drum and the amount of washing water supplied to the drum, a driving motion

22/104 drum can be controlled according to the amount of laundry in the drum in the water supply stage. That is, a drum driving motion capable of dissolving the detergent and wetting the laundry more efficiently can be selected based on the amount of dirty laundry in the drum.

The step of determining the amount of laundry configured to determine the amount of laundry accommodated in the drum can be implemented prior to the water supply step. Based on the determined amount of laundry, the drum driving movement can be differentiated in the water supply stage.

The amount of laundry can be determined by measuring the electrical currents used to drive the drum. For example, the currents used to implement a rotating movement can be measured. To implement the rotating movement, the control part controls the drum to be rotated at a certain RPM, for example, 46 RPM. A current value required to drive the drum where the RPM can be different, depending on the amount of laundry in the drum. Thus, the amount of laundry can be determined based on the amount of current needed to drive a particular drum at a given RPM in a particular movement.

If the amount of laundry is relatively large, sufficient washing water can be provided for the laundry at an early stage of the water supply step and laundry washing efficiency can be improved. The driving motion of the drum can be differentiated according to the amount of laundry in the water supply step and the parameters of the water supply step can be appropriately determined.

A.1.2 Water Supply (S733):

A.1.2.1 Determination of Detergent Type (S734):

In the initial phase of the water supply step, a detergent type determination step can be implemented to determine whether the detergent provided during the initial phase of the water supply step is a type of liquid or type of powder. This step is implemented to determine a drum driving movement or the number of rinses in the rinsing cycle, which will be implemented after the washing cycle. Information regarding the wash cycle and the rinse cycle can be made available to the user via a display piece 119 in an initial operation of the washing machine. Because of this, the detergent type determination step can be implemented in the initial phase of the

23/104 water, specifically, before a detergent dissolution step.

A. 1.2.2 Detergent Dissolution Promotion (S735):

As the washing water and detergent are supplied in the water supply step, the detergent dissolution step can be implemented. To improve the efficiency of the washing cycle, the detergent can be dissolved more completely and effectively in the initial phase of the water supply step. As a result, promoting detergent dissolution can be implemented in the water supply step to promote detergent dissolution.

A movement, that is, the driving motion of the drum to move the laundry inside the drum to promote detergent dissolution can be a movement configured to provide a mechanical force for the washing water and the laundry. For example, a step motion configured to repeatedly lift the laundry along the rotating drum and to drop the laundry from a circumferential inner surface of the drum according to a brake applied to the drum can be implemented in the dissolution promotion step. Alternatively, a rubbing motion configured to lift the laundry along the rotating drum and loosen the laundry according to the brake and reverse the rotation of the drum to lift the laundry can be implemented instead of the stepwise movement. The step movement and the rubbing movement are movements configured to apply a sudden brake to the rotating drum, suddenly changing the direction of movement of the clothing and giving a strong shock to the clothing. In addition, the step movement and the rubbing movement are configured to also apply a strong shock to the wash water. As a result, strong mechanical strength is provided at the initial stage of the water supply step to promote detergent dissolution and to improve the efficiency of the wash cycle accordingly.

In alternative modalities, the step of promoting the dissolution of the detergent can be implemented by repeating the sequential combination of the movement per step and the rubbing movement. In this case, two types of drum driving movements are combined several times and the washing water flow patterns can be further diversified to improve the efficiency of the washing cycle.

In a typical water supply step, the drum would be driven in a rotating motion that continuously rotates the drum in a predetermined direction at a predetermined speed to lift and release the laundry. At the

24/104 However, it turns out that the time required to dissolve the detergent in washing water in the rotating motion of the can be longer than in any step or rubbing movements, or a combination of these. For example, the time to dissolve the detergent in the rotating motion in an exemplary washer can be about 15 minutes, while the time required to dissolve the detergent in the washing water in the step motion or scrubbing motion using the same washing machine it can be 9-10 minutes. Thus, the movement by step or scrubbing can dissolve the detergent in the washing water faster, and the corresponding time of the specific washing stroke can be reduced.

In the step and scrubbing movements, the laundry is dropped and the shock of falling is applied to the laundry, while the rotation and stopping of the drum can generate a strong vortex in the washing water.

In addition, a circulation step configured to circulate the washing water carried out in the tub and to replenish the washing water to the drum can be implemented in the step of promoting detergent dissolution. In the circulation stage, the washing water kept below the drum is fed into the drum, continuing to promote the dissolution of detergent and wet the laundry.

In certain embodiments, the detergent dissolution promotion step can be implemented for, for example, about 2 minutes, or another amount of time as appropriate, until the water supply is complete. The water supply can be completed in the detergent dissolving step or water can be provided additionally because a water level can be decreased in a next step of wetting the laundry. The detergent dissolution promotion step can be implemented for a relatively short time, so as not to significantly harm the fabric with the impact on the clothes. As a result, a movement of driving the drum in the step of promoting detergent dissolution of each stroke above can be the movement of rubbing, depending on the amount of laundry in the drum.

That is, the step of promoting detergent dissolution can be implemented if the determined amount of laundry is a predetermined level or less, depending on the drum driving movements configured to provide strong mechanical strength can be more effective with small amounts of clothes and because small amounts of clothes can maintain sufficient contact with the washing water. Specifically, the small

25/104 amount of laundry indicates that a surface area of the laundry that has to come into contact with the washing water is small and that the dissolution of the detergent and wetting of the laundry can be implemented by the mechanical force applied to turn the laundry into one relatively short time. As a result, stepping or scrubbing motion allows washing efficiency to be improved and washing time time is reduced accordingly.

In contrast, if the determined quantity of laundry, in the laundry quantity determination step is a predetermined or higher level, the detergent dissolution promotion step can be ignored. That is, if the amount of clothing is relatively large, the mechanical force is not sufficient for the clothing to make sufficient contact with the washing water, because the washing water cannot be supplied / absorbed by the bundled clothing in a sufficient amount.

As a result, if the laundry amount is a predetermined level or higher, the step of promoting detergent dissolution is omitted and the wetting step starts immediately. If the amount of laundry is the predetermined level or higher, the laundry can make better contact with the washing water to promote detergent dissolution using the circulation step in the water supply step.

A.1.2.3 Wetting of clothing (S736):

A step of wetting the clothes sufficiently with the washing water can be implemented in the water supply step, together with the dissolution of the detergent. In the case of a drum-type washing machine, the laundry is not necessarily fully submerged in the washing water, and thus wetting the laundry can be implemented quickly at an early stage of the washing cycle. After the detergent dissolution step, a wetting step can be implemented to promote wetting of the laundry. This step can be implemented after the water supply step is implemented to a predetermined degree or until the water supply step is completed to ensure that the garment is sufficiently saturated. Alternatively, the detergent dissolution step can be implemented after the water supply is complete. The water level is decreased at the wetting stage and additional water supply can be implemented.

The wetting step can be partially implemented in the wetting step

26/104 detergent dissolution mentioned above and a water level can be increased enough to allow the wash water to be collected inside the drum. Because of this, the step of promoting the wetting of clothes can be implemented after the step of promoting the dissolution of detergent. A movement of driving the drum of the wetting step can be controlled differently compared to the step of promoting the dissolution of the detergent. For example, the drum driving motion of the wetting promotion step may include a rolling motion and / or a filtering motion. In certain embodiments, the filtration movement and the scroll movement can be implemented sequentially.

The filtration movement is a movement in which the clothing is widely distributed to enlarge the surface area of the clothing, and so the filtration movement can be used to wet the clothing evenly. The rolling movement is a movement in which the laundry is repeatedly turned to make the washing water kept under the laundry contact drum evenly, and the rolling movement can also be applied to wet the laundry. To use these effects as much as possible, different drum driving movements, that is, the repeated / sequential application of filtering and rolling movements in a predetermined order can maximize the effect of the wetting step.

If the amount of laundry is a predetermined level or higher, the drum driving movement of the laundry promotion step may include the filtration movement. That is, in the filtration movement, the surface of the laundry is enlarged and the washing water is supplied in the filtration movement, and the laundry is distributed evenly, without being tangled up and the washing water is provided in the laundry in an even manner. Alternatively, or in addition to the filtration movement, the rotating movement can also be implemented.

If the amount of laundry is less than the pre-determined level, the movement of filtration and / or dropping can be used during the promotion step of wetting the laundry.

The user can select a level of contamination of the laundry from the selection option part 118 and a net motor starting rate can be differentiated according to this selection. However, the net performance rate in the water supply stage may not be differentiated according to the level of contamination selected, because the net performance rate in the water supply stage

27/104 water supply is pre-defined to optimize the dissolution of detergent and wet the clothes, and because the concern of unnecessary damage to the clothes cannot be ignored. If the net performance rate is decreased, detergent dissolution and wetting of the laundry cannot be sufficiently implemented.

The water supply step in the standard course may include the detergent type determining step, detergent dissolving promotion step and wetting promotion step described above. In alternative modalities, the detergent type determining step, the detergent dissolving step or the wetting step can be provided independently of the water supply step. In this case, the determinant step of the detergent, the step to promote the dissolution of detergent or the step to wet clothes can be implemented after the water supply is completed.

A. 1.3 Heating (S740):

The wash cycle includes the wash step. To prepare for washing, a heating step can be implemented between the washing and water supply steps.

The heating step can be configured to heat the washing water, using the heater provided in the tub or to increase the temperature of the washing water or the drum by means of steam supplied into the drum. Because of this, the heating step can be implemented or omitted, if necessary. That is, if you are using cold air or water to treat clothing, the heating step cannot be implemented. However, if the wash water temperature is pre-set to be higher than the cold water temperature because of a standard temperature associated with a selected stroke, or if the wash water temperature is selected to be higher than that the cold water temperature from option selection piece 118, the heating step can be implemented.

The driving motion of the drum in the heating step can be differentiated according to the amount of laundry. A rotating movement can be implemented in the heating step, regardless of the amount of laundry. However, as mentioned above, if the laundry amount is the predetermined or lower level, the rolling movement can be implemented in the warm-up step. That is, in case the laundry is relatively small, the repeated turning of the laundry at the bottom of the drum can be more effective in heating and washing than in the laundry distribution. Alternatively,

28/104 with a small amount of clothing in the warm-up step, a combination of the falling and rolling movements can be used, and with a large amount of clothing, the rotating movement can be used.

The heating step can include a heating preparation step configured to prepare for heating after the water supply step. This means that the water supply step is completed after the wetting of the laundry is complete. As a result, it is possible to determine the amount of laundry, more precisely after the water supply step, because wet laundry cannot be distinguished from dry laundry items based on the amount of laundry before wetting the laundry. For example, the amount of wet clothes can be determined greater than the actual amount, before the clothes get wet. As a result, in certain embodiments, a more accurate determination of the amount of laundry can be implemented in the heating step, before washing. If the heating step is omitted, a step corresponding to the heating preparation step can be implemented to determine the exact amount of clothing. That is, if the heating step is omitted, the step of determining the exact amount of laundry can be implemented before the washing step after the water supply step is completed.

A. 1.4 Washing (S742):

Once the water supply step and the heating step described above are completed, the washing step configured to wash the laundry can be implemented. A drum driving movement in the washing step can be a sequential combination of movements per step and / or rotation and / or rolling to apply mechanical force and move the laundry in different patterns to improve washing efficiency.

Alternatively, drum driving movement in the washing step can be a sequential combination of the filtration movement and the rotating movement to continuously provide washing water for the laundry to improve the washing efficiency generated by the detergent as well as the washing efficiency generated by the mechanical force applied to clothing.

As a result, the driving motion of the drum in the washing step can be differentiated according to the amount of laundry, because the driving motion of the drum capable of generating an ideal washing effect can be different depending on the amount of laundry. The amount of laundry can be the amount of laundry determined before the supply step

29/104 water or in the heating step. In the washing step, the drum driving movement can be differentiated according to the amount of laundry determined after the water supply step.

If the amount of laundry is at a predetermined level or higher, the driving motion of the drum may include the filtering movement and / or the rotating movement. If the machine is not equipped to circulate the washing water, only the rotating movement can be implemented. In the case of a large amount of laundry, washing water can be supplied to the laundry evenly and mechanical force can be applied to the laundry simultaneously to improve washing efficiency.

If the amount of laundry is a predetermined or lower level, the driving motion of the drum may include a stepping motion and / or a rolling motion to improve washing efficiency, the laundry is moved in various patterns with the mechanical force applied to clothing. In certain embodiments, the rotating movement can also be implemented with the step movement and / or the rolling movement.

As mentioned above, in the normal course, the drum driving movement in the water supply step, the heating step and the washing step can be diversified and the efficiency of the washing cycle can be improved accordingly. In addition, the driving motion of the drum at each stage can be differentiated according to the amount of laundry in the drum and the optimized washing cycle can be implemented accordingly.

If the user selects a level of contamination of the laundry from option selection piece 118, the net actuation rate of the heating step and the washing step can be differentiated. If the net performance rate is unnecessarily high in a case where the level of contamination is relatively low, the laundry would be unnecessarily damaged.

A.2 Rinsing cycle (S750):

A method of controlling a rinse cycle in Course A will be described with reference to FIG. 7. According to this modality, the wash cycle can be implemented as part of a single course, together with the wash cycle described above, or it can be implemented independently. Simply to facilitate the discussion, a method of controlling the wash cycle implemented after the wash cycle mentioned in the standard course will be described below.

10/30

A.2.1. First rinse (S751):

Once the rinse cycle is completed, a first wash step configured for water supply and to drive the drum to implement the wash can be performed.

One or more turning steps can be implemented in the course in each pattern of the washing cycle, the rinse cycle and the turning cycle. For example, spinning spinning after the washing cycle and spinning in the washing cycle can be implemented. These turning steps can be referred to as intermediate turning to be distinguished from the turning cycle which is the last cycle of the standard stroke.

A turn level can be determined based on the drum RPM. Typically, intermediate turns can be applied at about 200-400 RPM, and, for example, at approximately 400 RPM on a Sensitive Stroke, about 600 RPM on a weak stroke, about 800 RPM on a medium stroke, and about 1000 RPM in a strong stroke. The drum RPM for intermediate gyros can be selected based on a low resonance frequency and a high resonance frequency during operation according to the current operating parameters.

The resonance frequency is a value of the washing machine and the vibration of the washing machine is drastically increased close to the resonance frequency. If the drum is turned close to the resonant frequency and the laundry does not distribute evenly, the vibration of the washing machine will be increased very suddenly. As a result, if the spin is implemented at a predetermined RPM greater than the resonance frequency, a step of untangling clothing would normally be implemented to evenly distribute the clothing within the drum and vibration is felt. If the vibration felt is less than a predetermined value, an accelerated step can be implemented to be outside a resonant frequency range.

As water supply and rinsing are repeated more often in the washing cycle, the time required by the intermediate rotation implemented in the middle of the rinses would be longer. To address concerns about residual detergent remaining after the wash is complete, the wash steps can be implemented at least three times or more in the wash cycle. The intermediate run implemented at this time can add a significant amount of time to the wash cycle, resulting in an excessively long rinse cycle. According to this modality, the RPM in the turnover

10/31 intermediate implemented in the middle of the water supply and rinse can be differentiated. That is, the drum can be rotated at a predetermined RPM lower than the low resonance frequency at a predetermined specific intermediate speed and at a predetermined RPM greater than the high resonance frequency at another predetermined specific intermediate rotation.

When the specific intermediate swing is implemented at a lower RPM than the low resonance frequency, the time required for an auxiliary detangling step, the vibration amount sensing step and the acceleration step may be unnecessary, potentially reducing the time necessary for the wash cycle. The RPM of this intermediate spin can be set to be approximately 100-110. In contrast, if the specific intermediate run is implemented at RPM less than the low resonance frequency, the time required for the wash cycle may be reduced, but the wash water, including detergent, may not be completely discharged.

Most contaminants and detergent residues can be found in the wash water after the wash cycle. Because of this, washing water can be discharged from laundry as exhaustively as possible after the wash cycle.

A high speed spin (S752) can be implemented in the first phase of the first washing step, after the washing cycle in the normal course. Rotating at high speed, the drum can be rotated at a higher RPM than the high resonance frequency such that a maximum amount of wash water can be discharged from the laundry. For example, the RPM can be adjusted to about 1000 rpm. The high-speed turning step can continuously rotate the drum at high speed, that is, about 1000 RPM, regardless of the user's selection, so that detergent remnants can be discharged as thoroughly as possible before rinsing.

Once the high spin speed is completed, a first step of driving the drum (S753) can be implemented to drive the drum after water supply to rinse the laundry. A wash water level can be a relatively high level allowing the water level to be visible through the door, so that the laundry is submerged in the wash water. Thus, a significant amount of washing water can be provided to rinse the laundry at an early stage of the washing cycle.

A drum driving motion in the first drum driving stage can be a rubbing and / or swinging motion to move the maximum amount of laundry submerged in the washing water to improve the washing performance. These wiping and oscillating movements correspond to a process of continuous hand rubbing of the laundry with the washing water after submerging the laundry in the washing water. The rotating and step movements correspond to a process of repeated movements of the laundry in and out of the washing water. As a result, the first step of driving the drum can control the drum to be driven in the rubbing and / or oscillating motion, with a high water level, allowing the user to visually recognize that sufficient rinsing is implemented. In alternative modalities, the circulation step configured to circulate the washing water kept in the tub inside the drum can be implemented in the first stage of driving the drum. Washing water is poured into the drum to rinse the laundry. This process can be referred to as jet rinsing. This also shows a user, as can be seen through the door, that sufficient rinsing is implemented.

Once the first stage of driving the drum is completed, a first stage of drainage and intermediate turning (S754) can be implemented. During the drainage of water, the drum can be driven in step and / or rotating motion. The laundry is lifted and dropped to improve washing efficiency and bubbles are generated to improve washing efficiency. The drum driving movement can be differentiated according to the amount of laundry. In the case of a small amount of laundry, the drum is activated in the movement per step to generate the maximum distance between lifting and falling. In the case of a large amount of laundry, the drum can be driven in the rotating motion.

The intermediate turn can be applied at about 100-110 RPM in the initial drain and intermediate turn. Then, the untangling step, the vibration detection step and the acceleration step can be omitted and the time required can be significantly reduced.

In alternative modalities, in the first stage of drainage and intermediate rotation in a standard course, the intermediate rotation can be implemented at approximately 400 RPM more than the low resonance frequency. In this case, the step and / or rotating movement can be implemented when the water is drained and the laundry is sufficiently distributed. Due to this,

33/104 the unwinding step of clothing can be omitted. Even at a rotation speed greater than the low resonance frequency, the intermediate rotation can be implemented for a short time, with the vibration sensitization stage and the single acceleration stage. Such an intermediate turn can be implemented in a relatively high ROM to release detergent remnants and contaminants that cannot be released through the high speed turn step. However, in a case where the amount of vibration measured in the vibration sensitization step is outside the allowed variation, the vibration sensitization step can be repeated to fail to enter the acceleration step, and the rinse time can disadvantageously increased. Because of this. Because of this, the vibration sensitization step can be implemented at a drum speed of approximately 100 to 110 RPM and in case the acceleration step fails to start at predetermined times of vibration step implementations, the first step of drainage and intermediate turning can be completed.

A.2.2 Second Rinse (S756) and Final Rinse (S760):

A second rinsing step (S756) can follow the first rinsing step. The second rinsing step can include a second drum drive step (S757) and a second drain and intermediate turn step (S758). The second drum drive step can be essentially the same as the first motor drive step described above. In addition, the second stage of drainage and intermediate swing can be essentially the same as the first stage of drainage and intermediate swing. However, the intermediate swing is implemented at approximately 100 to 110 RPM in the second drainage stage and intermediate swing to reduce the rinsing time, since the detergent remains have already been released in the high-speed swing stage and in the first drainage and intermediate turning.

The rinse cycle can use the result of determining the detergent type determination step.

If the detergent is of the liquid type, relatively little detergent will remain and the second rinsing step can be omitted to reduce the time required by the rinse cycle. If the detergent is a powder type, the first rinsing step and the second rinsing step can be performed by default.

If the detergent is a liquid type, a third rinsing step (S760) can serve as a final rinsing step after the first rinsing step. If the detergent is of the powder type, a third rinsing step may

34/104 serve as a final rinse step after the second rinse step. However, when the bubbles are felt in the third rinse step (in the case of a powder type detergent), a fourth rinse step as the final rinse step can be implemented.

A water level in the final rinse step (S760) can be a relatively low level. In the case of an inclined drum washing machine having an inclined drum at a predetermined angle, a water level may be a predetermined level sufficient to supply water only to a predetermined posterior portion of the inclined drum. That is, the water level can be so that it is not felt, or visible, outside the washing machine. However, such a water level is predetermined so as not to generate more bubbles in the laundry. Even if bubbles are generated, they are generated in the vat, not in the drum, to prevent excess accumulation. As a result, the user can visually identify that no bubbles are generated in the final rinse step and the satisfaction of the rinse performance can be improved.

A third drainage step (S762) can be implemented after the third drum drive step (S761) in the final rinse step, to implement the turning cycle. The drum can be operated in the step and / or moved by friction to distribute the laundry to be washed evenly in the third drainage step.

A.3 Turn Cycle (S770):

A method of controlling the turning cycle in the standard stroke will be described with reference to FIG. 7. The spin cycle can be implemented as part of the standard stroke, along with the wash cycle and the rinse cycle, or independently as a single stroke. Simply to facilitate the discussion, a method of controlling the spin cycle implemented after the wash cycle and the rinse cycle composing the standard stroke will be described.

A.3.1 Unwrapping Laundry (S771):

The spinning cycle may include a step of unwinding laundry to be configured to unwind the laundry by operating the drum to distribute the laundry evenly. The spin cycle is provided to minimize the vibration generated when the drum is spun at high speed. If the drum is driven in the friction step and / or movement in the drainage step just before the turning cycle, the laundry will probably be unwound to a degree pre-determining by the friction step and / or movement and the time required by the step of unwinding laundry to wash can be significantly

35/104 reduced.

A.3.2 Eccentricity Measurement (S773):

After the laundry unwinding step, the amount of eccentricity with drum rotation at a predetermined RPM below the low resonance frequency for a predetermined period of time, can be measured by accelerating the drum and determining whether the laundry to washing is evenly distributed in the drum.

A step of measuring the eccentricity of a spin cycle in a standard stroke according to another modality can be implemented before a step of unwinding laundry. A significant amount of unwinding of laundry to be carried out may have been implemented by driving the drum of the rinsing cycle. As a result, the turning cycle can be started with the eccentricity measurement step to reduce the turning cycle time. If the measured eccentricity compared to a reference value is determined to be satisfactory, the acceleration, which will be described later, can be implemented. If the measured eccentricity is not satisfactory compared to the reference value, the step of unwinding laundry can be implemented. The drum can be operated in the step movement of the laundry unwinding step to promote the laundry unwinding and the eccentricity measurement step can be restarted after the laundry unwinding step.

A.3.3 Acceleration and Normal Turn (S775):

After the eccentricity measurement step, a step of accelerating the drum rotation to normal turning RPM (acceleration step) can be implemented. After that, a normal spin stage configured to spin the drum at normal spin RPM can be implemented to complete the spin cycle. The rotation speed of the normal swing drum can be standardized to be approximately 1000 RPM. That is, the amount of moisture contained in the laundry can be reduced as much as possible to minimize detergent residue. The RPM of the normal spin can be changeable according to the user's selection, since the RPM of the normal spin is related to a level of residual moisture and wrinkle level of the clothing after the conclusion of the spin cycle. As a result, the user can select RPM of the normal spin stage, relating to a wrinkle level moisture level of the laundry to wash.

10/36

B. COURSE B (HEAVY CONTAMINANT COURSE):

A course B of heavy contaminants in which heavy dirt must be removed from laundry items will be described with reference to FIG. 8. The course of heavy contaminants can be selected in the course selection part 117 (S810).

B.1 Washing Cycle (S830):

B.1.1. Determining the Amount of Laundry to Wash (S831):

Once the course of heavy contaminants is selected, a step of determining the amount of laundry to be washed can be implemented to determine the amount of laundry to be placed in the drum. The method for determining the amount of laundry to be washed can be similar to that described above with respect to the standard course, so a repeated description of it will therefore be omitted. The step of determining the amount of laundry to be washed could be implemented before the course selection step.

The control piece compares the amount of laundry to be determined in the step of determining the amount of laundry to be washed with a reference value and controls the drum drive movements of a water supply step and a wash step, which will be described later, based on the comparison result. Essentially, a given amount of laundry to be greater than a reference value can be considered with a large load, and an amount of laundry to be washed less than the reference value can be considered a small load. The drum drive movements for each stage according to the amount of laundry to be determined will be described.

B.1.2 Water supply (S833):

In a water supply step, the control part controls the water supply device (eg the water supply path and the water supply valve) connected to the water supply source and the tub to supply the water from tub wash. If the amount of laundry to be measured in the step of determining the amount of laundry to be washed is less than a reference value, the control piece can control the drum driven in the rotating movement and / or in the step movement and / or movement rubbing and / or filtering and / or rolling motion.

First, if the washing clothes placed on the drum were unrolled, the eccentric rotation of the drum would be generated, and the control piece could

37/104 control the drum to be activated in the rotating movement in the water supply step to unroll the laundry. In the rotating motion, the drum is rotated in a predetermined direction and the laundry to be washed is thrown at the lowest point of the drum from a position of approximately 90 ° or more with respect to the direction of rotation of the drum, so that the laundry to wash rolled can be rolled out and distributed evenly.

The control piece controls the drum to be rotated in the step movement and / or scrubbing movement so that a drop shock is applied to the washing clothes placed in the drum. The step and friction movement can be applied to gently remove insoluble contaminants. As a result, once the drum is activated in the step movement and / or scrubbing movement, insoluble contaminants can be removed in the water supply step, and the washing time is reduced and improved washing efficiency can be achieved. .

The water supply step provides washing water for the tub and wets the washing clothes placed in the drum, as mentioned above. Because of this, the control piece can drive the drum in the filtration movement after the step movement and / or rubbing movement to wet the laundry to be washed.

In addition, the control piece can drive the drum in the rolling motion to dissolve detergent in the washing water in the water supply step, in addition to the movement and rolling, to wet the laundry to be washed in the washing water, before the completion of the water supply stage.

If the amount of laundry to be washed is greater than a reference value, the control piece can control the drum to be activated in the rotating and / or filtering movement, in the water supply stage. If the amount of laundry to be washed is relatively large, specifically, greater than the reference value, the drum movement configured to apply a sudden brake to the drum such as the step movement and / or rubbing movement may apply a lot of load on the engine. By extension, the original effect of the step movement and / or friction that is the application of the fall shock cannot be achieved. Thus, the step movement and / or friction is not implemented if a large amount of laundry is placed on the drum. In addition, if a large amount of laundry to be placed on the drum, the wetting effect of laundry to be generated by the scrolling movement having the rotation speed relatively

38/104 low cannot be effectively achieved, and instead the rotating movement can be implemented to wet clothes for washing. Eventually, if the amount of laundry to be washed is greater than the reference value, the drum may be activated in the rotating and / or filtering motion so that the effects of the laundry distribution, the removal of insoluble contaminants, the wetting washing and detergent dissolution mentioned above can be achieved.

B.1.3 Washing (S835):

After the water supply step is completed, the step of washing the heavy contaminants course can begin. The step of washing the heavy contaminants course may include an immersion step, a contaminant removal step and a remaining contaminant removal step. In this case, the washing water having different temperatures can be supplied at each stage and each stage can therefore be implemented.

B.1.3.1 Immersion (S836):

The immersion step is a process of immersing the laundry to be washed in cold water to loosen the heavy contaminants contained in the laundry. Relatively cold water having a temperature of, for example, approximately 15 C is used in the immersion step, to loosen protein components contained in the heavy contaminants attached to the laundry to wash for a long time. If these protein components come into contact with heated water, these heavy contaminants tend to be solidly solidified in the laundry and it is difficult to separate them from the laundry. Because of this, the immersion step can be implemented using cold water, to prevent heavy contaminants having the protein components from being attached to the laundry.

If the amount of laundry to be washed is less than a predetermined value, the motor can drive the drum in the step movement. Rotating motion and / or rolling motion can be added after the step motion. Since the step movement has excellent washing capacity and reduced washing time, heavy contaminants attached to the laundry can be immersed and a shock applied to the laundry. As a result, the step movement has an effect of inducing separation of heavy contaminants from the laundry.

If the amount of laundry to be washed is greater than the reference value, the drum can be operated in the rotating and / or rolling motion

39/104 in the immersion stage. That is, if the amount of laundry to be measured is greater than a predetermined reference value, the step movement cannot be implemented due to the excessive load that would be applied to the engine. As noted above, the step movement applies a drop shock to the laundry to be washed inside the drum to improve washing efficiency. However, if the amount of laundry to be washed is large, the step movement may not be implemented. When the amount of laundry to be washed is greater than a reference value, the step movement is also not implemented in the steps of removing contaminants and removing remaining contaminants that will be described later.

B.1.3.2 Removal of Contaminants (S837):

After the immersion step, a contaminant removal step configured to heat wash water in the range of 35 ° C to 40 ° C to remove heavy contaminants can begin. The temperature of the washing water used in the contaminant removal step is set at 35 ° C to 40 ° C because the oil components contained in the heavy contaminants can be removed more easily at a temperature that is similar to a human body temperature. The heater provided on the bottom surface of the tub or the moisture supply device configured to deliver heated moisture such as steam to the tub can be used to increase the temperature of the wash water to the predetermined range.

In the contaminant removal step, the control piece can control the motor to drive the drum in the rotating and / or rolling motion if the amount of laundry to be washed is the reference value or less. Rotating and / or rolling motion can apply low load on the engine and reduce the washing time, with high washing efficiency. Because of this, the reduction of washing time can be achieved.

If the amount of laundry to be washed is greater than the reference value, the control piece can control the drum to be operated in the rotating motion. In the case of a large amount of laundry to be washed, the rolling motion configured to spin the drum at a relatively low speed may not be effective in removing contaminants, and thus the rotating motion may be applied.

B.1.3.3 Removal of Remaining Contaminants (S838):

The control piece can implement a remaining contaminant removal step configured to heat the wash water to

40/104 have a temperature of approximately 60 ° C and to sterilize and bleach the laundry to wash, after the contaminant removal step. The wash water temperature can be approximately 60 ° C or more in the step of removing remaining contaminants to sterilize and bleach the laundry.

In the step of removing remaining contaminants, the control piece can control the drum to be triggered in the step movement or in the order of the step movement and / or rotating movement and / or rolling movement, if the amount of laundry to be washed is below the reference value.

If the amount of laundry to be washed is greater than the reference value, the control piece can control the drum to be driven in the filtration movement and / or in the rotating movement in the step of removing remaining contaminants.

B.2 Rinse cycle (S850):

The rinse cycle for the heavy contaminants course can be similar to the rinse cycle for the standard course described above and rinse cycles for the other courses that will be described later. Thus, repeated description of the rinse cycle will be omitted.

B. 3. Turning Cycle (S870):

The turning cycle of the course of heavy contaminants can be similar to the turning cycle of the standard stroke described above and cycles and turning of the other courses that will be described later. Thus, the repeated description of the turn cycle will be omitted.

C. COURSE C (QUICK BOILING COURSE):

Course C will be described with reference to FIG. 9. Stroke C may be called a “rapid boiling stroke” configured to heat the washing water to a predetermined temperature for a relatively short time to achieve a sanitary boiling effect of laundry to be washed, such as in a washing cycle. sanitization.

Generally, when sterilizing and bleaching the laundry, the washing water contained in the tub is heated to a pre-established temperature and then washing is carried out. Since the washing time is relatively long and the electrical energy is quite consumed to heat the washing water only, a lot of time and electrical energy is spent to heat the washing water contained in the tub to the pre-established temperature. In the course of rapid boiling, laundry can be sterilized and bleached while also reducing overall washing time and energy consumption. The rapid boiling stroke

41/104 heats the wash water supplied to the tub for a pre-set period of time, regardless of the wash water temperature, instead of heating the wash water until the wash water reaches the pre-set temperature. To take the washing capacity into account, a time compensation step 5 of a washing step provided in the rapid boiling stroke according to the wash water temperature can be included in this washing stroke, as will be described in reference to FIG. 9.

First, the user can select the rapid boiling stroke from the selection and stroke part 117 (S910). Then, the control piece implements a time setting step of the washing step of the rapid boiling stroke. This step of setting the wash time allows the control piece to determine the time required by the wash step of the rapid boiling stroke, which is stored in a storage device, such as a memory. This step can be implemented simultaneously with the course selection step or a water supply step.

C.1 Wash cycle (S930):

C.1.1 Determining the Quantity of Laundry to Wash and Setting the Wash Time (S931):

Once the user selects the rapid boiling stroke, the control piece can implement a wash quantity determination step to measure the amount of laundry to be washed and a wash time setting step configured to establish the time required for a wash step of the rapid boiling stroke based on the predetermined amount of laundry to wash. The control piece can use the time taken to spin the drum to a predetermined position to determine the amount of laundry to be washed, as described above, or the residual rotation time after spinning the drum for a predetermined time.

In the wash time setting step, the control piece can select a wash time corresponding to the amount of laundry to be measured from the appropriate times stored in memory. The variety of time required by the rapid boiling stroke washing step is stored in the storage device, such as memory, so that when the rapid boiling stroke is selected, an appropriate time stored in memory can be selected by the control.

³⁵ C-1 -2 Water Supply (S933):

The wash cycle of the rapid boiling stroke may include a

42/104 water supply configured to supply wash water to the vat. In the water supply step, the control part controls the water supply device (e.g. via water supply and water supply valve) connected to the water supply source and the tub to supply water to the tub. In addition, the control part controls the drum to be driven in a drum drive movement similar to the drum drive movement of the water supply step, for example, the heavy contaminant stroke described above, and thus further detailed description will be omitted.

C.1.3 Water Temperature / Compensation Measurement Step (S935):

As soon as water is supplied to the tub, the control piece measures the temperature of the washing water using a temperature sensor on the washing machine and compares the measured temperature with a reference temperature to adjust the time of the washing step.

For example, the control piece can compare the measured wash water temperature to a reference temperature, for example, greater than approximately 50 ° C. If the measured temperature is higher than the reference temperature, for example, if the heated water is supplied to the tank, the control piece can implement the washing step immediately. However, if the measured temperature is below the reference temperature, the control piece can implement a compensation step configured to adjust the wash step time.

As mentioned above, the washing step can be implemented after heating the washing water for the period of time predetermined in this course, regardless of the water temperature. Because of this, the temperature of the water maintained in the vat may be different, depending on the temperature of the water supplied to the vat after the completion of a heating step, and there would be a difference in the washing capacity due to the difference in the water temperature. As a result, the compensation step is provided to minimize the difference in washing capacity caused by the washing water having different temperatures after the heating step. If the wash water temperature is below the reference temperature, the wash step time is increased to compensate for the wash capacity at the lower temperature.

The number of reference temperatures used to define a temperature variation can be adjusted accordingly. For example, in a

43/104 modality, a single reference temperature can be provided, and in alternative embodiments, a plurality of reference temperatures can be provided. When the wash water temperature is higher than the first reference temperature (eg 50 ° C) and there are three reference temperatures, ie 5, first, second and third temperature are provided, the control piece can implement the wash step immediately. When the measured wash water temperature is below the first reference temperature and above the second reference temperature, the second reference temperature (e.g., 40 ° C), being lower than the first reference temperature (e.g.

50 C), and when the measured temperature is below the second reference temperature and above the third reference temperature, the third reference temperature (e.g. 30 ° C) being less than the second reference temperature (e.g.

C), and when the measured temperature is lower than the third reference temperature, the compensation step configured to compensate for the time of the washing step preconfigured in the washing time setting step is performed.

When the wash step time is compensated, the wash step time is compensated, the control piece can control the compensated time to be different depending on the wash water temperature. The washing capacity is substantially proportional to the temperature of the washing water. Because of this, the lower the measured wash water temperature, the longer the compensated time. The reference temperature and time variation added in the compensation step can be pre-configured based on the capacity of the washing machine and other factors.

²⁵ C.1.4 Heating (S937):

Once the pre-established washing step time is compensated in the compensation step, a heating step configured to remove contaminants contained in the laundry to be washed by moving the drum and to heat the washing water simultaneously can be 30 implemented for a predetermined period of time. The heating step can be implemented as an independent step or as a part of a washing step to be described later. Simply to facilitate the discussion, in this course description, the heating step will be described as part of the washing step.

C. 1.5 Washing (S939):

A drum drive motor from the

44/104 rapid boiling may include step motion and / or rotating motion and / or rolling motion.

The step movement has excellent washing capacity and applies shock to the laundry so that contaminants attached to the laundry can be separated and the washing time can be reduced. As a result, the control piece can rotate the drum in the step movement at an early stage of the washing step. In this case, the heating step can be implemented after the step movement of the washing step.

In the step movement, the drum is spun at a predetermined speed allowing the laundry to wash does not fall off the inner circumferential surface of the drum due to centrifugal force. When laundry is located near the highest point of the drum, reverse torque is applied to the drum. Once the liquid actuation ratio of the step movement is adjusted, the load applied to the motor is greater in the step movement than in the other movements. Because of this, if the heating step configured to heat the washing water is continued during the step movement, the energy consumption would be increased and a safety problem could occur due to the increase in the amount of current. As a result, the heating step can be implemented for a predetermined time after the completion of the step movement.

The heating step is configured so that the heater is not activated for a pre-established heating time period, and not necessarily until the wash water temperature reaches the pre-established value. This allows the time and electricity required by the washing step to be precisely predicted and the user to be notified of the predicted data. In addition, the washing step can be implemented only for essentially the same pre-established time, regardless of the temperature of the washing water provided in the washing step, so that energy consumption and washing time can be reduced.

Therefore, the control piece can control the rotating motion and / or the rolling motion to be implemented. In this case, the rotating movement and / or rolling movement can be implemented simultaneously with the start of the heating step. The rotating and rolling motion apply a low load to the engine and have good washing capacity, with reduced washing time. As a result, the rotating motion and the rolling motion can achieve an effect of reducing the washing time required by the

45/104 washing step and an effect of an appropriate washing capacity even with the washing step implemented using the washing water having different temperatures.

C.2 Rinse cycle (S950):

A rinse cycle of the rapid boiling stroke may be similar to the rinse cycles of the strokes described above and rinse cycles of other strokes to be described later. Thus, additional detailed description of it will be omitted.

C. 3 Turn Cycle (S970):

A turn cycle of the rapid boiling stroke can be similar to the turn cycles of the strokes described above and turn cycles of the other strokes that will be described later. Thus, additional detailed description of it will be omitted.

D. COURSE D (COLD WASHING COURSE):

A Cold Wash Course D will be described with reference to FIG. 10. The Cold Wash Course D is configured to wash clothes without heating the wash water, providing energy savings without degrading a desired washing capacity. As a result, this stroke measures the temperature of the washing water supplied to the tub, the measured temperature is compared to a pre-established temperature and the operating parameters are adjusted accordingly, allowing the washing capacity to be maintained. For example, if the wash water temperature does not reach a reference temperature based on the result of the comparison, the wash time is compensated enough to provide a target wash capacity in the cold wash course.

First, the user can select the cold wash stroke from the stroke selection part 117 (S1010). Once the user selects the cold wash stroke, the control piece can implement a wash cycle, a rinse cycle and / or a spin cycle sequentially or selectively.

D.1 Washing Cycle (First Mode) (S1030):

D.1. Laundry Quantity Determination / Wash Time Setting (S1031):

Once the user selects the cold wash course, the control piece can implement a wash quantity determination step configured to measure the amount of laundry to be washed and a wash time configuration step configured to establish the time

46/104 required by a wash step of the cold wash course based on the measured amount of laundry to wash. In the step of determining the amount of laundry to wash, the control piece can use the time taken to spin the drum to a predetermined position or the residual drum rotation time to measure the amount of laundry to be washed, as described above. In the washing time setting step, the control piece can select a washing time corresponding to the amount of laundry to be measured from the appropriate times stored in memory according to the amount of laundry to be washed.

D.1.2 Water supply (S1033):

The wash cycle of the cold wash stroke may include a water supply step configured to supply water to the tub. In the water supply step, the control part controls the water supply device (e.g. via water supply and water supply valve) connected to the water supply source and the tub to supply water to the tub. In addition, the control piece controls the drum to be driven in a drum drive movement similar to the drum drive movement of the water supply step of the heavy contaminants or rapid boiling stroke described above. Thus, additional detailed description of it will be omitted.

D.1.3 Water Temperature Measurement / Wash Time Compensation (S1035):

Once the washing water is supplied to the tub, the control piece will be able to measure the temperature of the washing water using a temperature measuring device provided in the washing machine. The control piece can compare the measured temperature with a reference temperature (e.g. 15 ° C). If the measured temperature of the washing water is the reference temperature or higher, the control piece can implement the washing step without compensating the washing time according to the amount of laundry to be washed. If the measured temperature is below the reference temperature, the control piece can implement the washing time compensation step. In this example, the temperature of “15C” is presented as an example of a critical temperature capable of ensuring a washability in cold wash and a reference temperature of a washability test using cold water. As a result, if the measured wash water temperature is below the reference temperature, the control piece can adjust the time

47/104 of the wash step established in the wash time setting step. For example, if the measured temperature is below the reference temperature, the control piece can add a predetermined time to the wash step time to prevent deterioration of the wash capacity due to the use of cold wash water having a lower temperature reference value. For example, if the measured wash water temperature is less than approximately 10 ° C, 10 minutes can be added to the wash step time in the wash time compensation step. If, for example, the measured temperature is above 10 ° C and below 15 ° C, 5 minutes can be added to the time of the washing step.

D.1.4 Washing (S1037):

Once the washing step time has been compensated, the amount of laundry to be measured in the washing amount determination step mentioned above is compared to a reference laundry amount value and a washing step including different drum drive movements different implemented according to the amount of laundry to be implemented. The reference amount of laundry load can be pre-established based on an amount of laundry load that allows the step movement to be carried out, taking into account the size of the drum and the motor output. For example, the reference amount of laundry to be washed may be half the value of the washing capacity of the washing machine (approximately 5 ~ 6 kg in a washing machine having a capacity of 11 kg). A case in which the measured laundry quantity value is less than the reference laundry quantity value will be described first, and then a case in which the measured value is the reference value or more will be described.

When the measured laundry load value is less than the reference laundry load value, the control piece controls the step movement and / or the rotating movement and / or the rolling movement to be implemented in the step washing. The step movement applies the drop shock to the laundry to be placed in the drum and contaminants contained in the laundry to be washed can be removed easily, even if cold water is used. If the laundry is rolled up during the washing step, eccentric rotation of the drum may be generated. Thus, the control part drives the drum in the rotating and / or rolling motion to unwind and distribute the

48/104 rolled laundry.

When the measured laundry quantity value is the reference value or higher, the control piece controls the filtration movement and / or the rotating movement to be implemented in the washing step. If the amount of laundry to be washed is the reference value or higher, the large load quantity makes it difficult to achieve the effect of shocking the laundry to wash in the step movement and the rolling effect of the laundry to wash along the surface internal circumferential shape of the drum in the scrolling motion. Because of this, the filtering movement and the rotating movement can be implemented, individually or sequentially, to achieve the effect of ensuring the washing capacity and the distribution effect of the laundry to be washed.

D. Washing Cycle (Second Mode) (S1130):

FIG. 11 is a diagram of a cold wash course according to a second embodiment as widely described in the present document.

In comparison to the cold wash stroke according to the first mode, the cold wash stroke according to the second mode omits a wash time setting step and a compensation step and instead heats the wash water using the heater if the wash water temperature is below 15 ° C. That is, in a washing cycle according to the second mode, the amount of laundry to be washed is determined (S1131) and a water supply step (S1133) can be implemented immediately without establishing the washing time. After that, the wash water temperature is measured (S1135) to implement the wash step (S1137). A drum drive movement of the drum can be differentiated according to the amount of laundry to be washed in the washing step according to the second embodiment, which is similar to the first embodiment described above. The washing step according to the second embodiment can also include a heating step based on the measured temperature of the washing water.

A case in which the amount of laundry to be measured in the washing step is less than the reference value will be described, in which the drum drive movement includes the step movement and / or rotating movement and / or rolling movement.

When the measured wash water temperature is below the reference value, the step movement is implemented after the start of the wash step. After the step movement, a configured heating step

49/104 to heat the wash water using a heater or a moisture supply device provided in the tub can be implemented. The heating step starts after the step movement because the step movement applies increased load to the motor, as mentioned above. Thus, a safety problem as well as deterioration of washing capacity can occur if the heating step and the step movement are implemented simultaneously. In addition, if the heating step is implemented before the step movement to avoid the above problems, the washing time will increase disadvantageously. Thus, in this mode, the heating step starts after the completion of the step movement.

At the time of the start of the heating step, the control piece can implement the rotating and rolling motion sequentially. Rotating and rolling movements are not related to the deterioration of the washing capacity and safety and can reduce the washing time, even if they are implemented together with the heating step simultaneously.

The temperature of the washing water is measured again after the heating step and it is determined whether the temperature measured again reaches the reference temperature. When the wash water temperature reaches the reference temperature, the heating step can be completed. However, if the wash water temperature cannot reach the reference temperature, the heating step can be continued during the wash step. That is, even if the temperature of the washing water heated in the heating step does not reach the reference temperature, if the washing step is finished, the heating step will also be.

If the measured temperature is the reference temperature or higher, the control part activates the drum in the step movement and / or the rotating movement and / or the rolling movement essentially as the description of the movement of the drum according to the first modality, and thus, additional description of it will be omitted.

If the amount of laundry to be washed is the reference value or more in the washing step, the control piece can drive the drum in the filtering and / or rotating motion. At this time, the heating step can be provided if the measured wash water temperature is below the reference temperature. As described above, the drum is not driven on

50/104 step movement during the heating step.

D. 1’’Wash Cycle (Third Mode) (S1230):

FIG. 12 is a diagram of a cold wash course according to a third embodiment as widely described in the present document.

In comparison to the cold wash stroke according to the first embodiment described above, the cold wash stroke according to the third embodiment supplies hot water to the tub if the temperature of the wash water supplied in a water supply step is less than approximately 15 ° C. That is, after determining the amount of laundry to wash (S1231), the control piece can implement a water supply step (S1233) configured to supply washing water to the tub based on the determined amount of laundry to be washed, omitting a washing time setting time and a clearing step.

When implementing the water supply step, the control part supplies cold water to the tank (1234) and can also implement a water temperature measurement step (S1235) and the cold water supply simultaneously. In this case, when the measured wash water temperature is 15 ° C or more, a wash step (S1240) can be implemented according to the amount of laundry to be placed in the drum. If the measured temperature is below 15 ° C, a hot water supply step (S1236) can be implemented.

The water supply step can be continued until the amount of cold water and the amount of hot water supplied in the water supply step reaches the amount of wash water determined according to the amount of laundry to be washed. Once the water supply step is completed, a washing step implemented according to the amount of laundry to be washed can be started. The movement of the drum drive can be differentiated according to the amount of laundry to be washed in the washing step, similar to the first modality described above, so an additional detailed description will be omitted.

D.2 Rinse cycle (S1050, S1150, S1250):

A rinse cycle of the cold wash stroke can be similar to the rinse cycles of the strokes described above and rinse cycles of the other strokes to be described later. As a result, further detailed description of the same will be omitted.

D.3 Turn Cycle (S1070, S1170, S1270):

51/104

A cold wash stroke turning cycle can be similar to the turning cycles of the strokes described above and turning cycles of the other strokes that will be described later. As a result, further detailed description of the same will be omitted.

E. COURSE E (COLOR ITEMS COURSE):

Course E will be described with reference to FIG. 13. Course E can be referred to as a “Color Items Course” configured to wash colored clothing items more effectively. When washing colored items of clothing, a problem of color migration, which can generate a mixture of colors between colored items, fading, and a problem of formation of "balls" can occur. The color migration above is likely to be generated as the static friction between the drum and the laundry increases. This course may include a temperature control step configured to prevent color migration by controlling the temperature of the wash water, a step of washing colored items configured to drive the drum to prevent the formation of "balls", and a rinse step. In the following, the steps will be described in detail.

E.1 Washing Cycle (First Mode) (S1330):

E.1.1 Water supply (S1331):

In a water supply stage, the control part controls the cold water to be supplied to the tank. Color migration is more likely to occur in higher temperature wash water. In the water supply stage, the control part can control the motor to drive the drum in the turning movement or in the filtration movement or a combination of these. The water supply step can be provided to provide the washing water needed to wash the laundry in the tub and to wet the laundry placed in the drum in the washing water. As a result, the drum is activated in the filtration movement in the water supply step so that the wetting of the laundry can be implemented effectively. In addition, the drum can be operated in the turning movement in the water supply step, instead of in the filtration movement. The turning movement can minimize the movement of the clothes inside the drum, in comparison to other movements, to minimize the formation of “balls” that can be generated by the frictional force between the items of clothing.

E.1.2 Heating / Water Temperature Measurement Stage (S1333): Once the water supply stage is completed, the control piece can measure the temperature of the washing water supplied to the tub.

52/104

When the temperature measured is a reference temperature or higher (e.g. 30 C or 40 C), the control area can start the washing step immediately. When the measured temperature is below the reference temperature (e.g. cold water because the wash water supplied in the water supply step is cold water), the control piece can start a heating step configured to heat the wash water. In certain embodiments, the temperature (reference temperature) of the washing water that allows the start of the washing step can be set at 30 ° C or 40 ° C, since the temperature of the washing water capable of maximizing washing capacity, while minimizing color migration is in the range of 30 ° C to 40 ° C.

The heating step heats the wash water supplied to the vat using a heater provided on the bottom surface of the vat or a steam generating device configured to supply steam to the vat.

E.1.3 Washing (S1335):

When the heating step allows the wash water temperature to reach the reference temperature (30 ° C or 40 ° C), the control piece can start a wash step. In the washing step, the control piece can control the drum to be driven in a drum drive movement that can minimize the mechanical frictional force to prevent "ball" formation and to achieve the desired washing capacity. For example, the control part can control the drum to be driven in the turning movement and / or step movement, in the washing step of this stroke. Such a step movement and the turning movement can be implemented sequentially and the sequential implementation can be repeated.

The pivoting motion turns the drum in both opposite directions and causes the laundry to fall from a position of approximately 90 ° or less with respect to the direction of rotation of the drum. The turning movement applies rheostatic brake to the motor, since the physical friction applied to the laundry can be reduced as much as possible, while maintaining a predetermined level of washing efficiency. As a result, the possibility of formation of “balls”, which can be generated by friction between items of clothing or between clothes and the drum, can be minimized.

As mentioned above, the step movement rotates the drum at a predetermined speed allowing the laundry to wash does not fall off the inner circumferential surface of the drum by centrifugal force and then applies the sudden brake to the drum to maximize the shock applied to the clothes.

53/104

Because of this, the step movement has excellent washing capacity, sufficient to compensate for insufficient washing capacity of the turning movement. The amount of time in which the step movement is carried out may be shorter than the amount of time in which the turning movement is carried out to minimize the possibility of formation of "balls".

E.1'Wash Cycle (Second Mode) (S1430):

FIG. 14 is a diagram of a course of color items according to a second modality. Unlike the above course according to the first modality, the course of color items according to the second modality allows a water temperature measurement step and a heating step to be implemented in a wash step (S1433) after a water supply step (S1431). If the water temperature measurement step and the heating step were implemented before the washing step, the washing time would increase disadvantageously. As a result, this modality features a course of color items capable of reducing the washing time in comparison to the modality above.

After the water supply step (S1431), the control part can control the drum to be driven in the step movement and / or spin movement in the washing step and it can be determined whether the temperature of the washing water is a temperature (eg 30 ° C or 40 ° C) or more simultaneously. When the wash water temperature is the reference temperature or higher based on the result of the determination, the control part controls the drum to be driven continuously according to the wash step. When the wash water temperature is below the reference temperature, the control part can start a heating step configured to heat the wash water.

The control part can control the drum so as not to be triggered in the step movement in the heating step. That is, in the heating step, the control part drives the drum in the turning movement, not in the step movement. The reason why the heating step is not implemented together with the step movement simultaneously is described in the above courses, so additional detailed explanation will be omitted.

E.2 Rinse cycle (S1450):

The control piece can start a rinse cycle after the wash cycle is complete. The control part can control the drum to be operated in the filtration movement during the rinse cycle. The filtration movement rotates

54/104 the drum at the predetermined speed making sure that the clothes do not fall off the inner circumferential surface of the drum by centrifugal force and then spray washing water on the drum so that the filtration movement can be applied to wet or rinse the clothes. In addition, the filtration movement can generate little friction between the items of clothing and between the clothes and the drum. Because of this, the filtration movement allows the clothes to be rinsed in a relatively short time. The control part can implement the rotating movement in the rinse cycle to supplement the rinsing capacity of the filtration movement.

E. 3 Turn Cycle (S1470):

Upon completion of the rinse cycle, a rinse cycle configured to remove washing water from clothing can begin. The turning cycle of the course of color items can be similar to the turning cycles of the courses described above and turning cycles of the other courses to be described later, thus additional detailed description of the same will be omitted.

F. COURSE F (FUNCTIONAL CLOTHING COURSE)

Course F will be described with reference to FIG. 15. Course F may be called “functional clothing course” configured to wash functional clothing, including clothing for outdoor activities such as climbing clothes and other clothing intended for playing sports, effectively, without damaging the fabrics. Functional clothing is manufactured to be suitable for outdoor activities such as climbing, swimming, cycling and the like. Functional clothing absorbs sweat quickly and releases absorbed moisture, as well as helping to keep your body warm. However, these functional clothes are made of thin synthetic fabric and are more fragile than other types of fabrics. A washing course for functional clothing can be optimized to be suitable for functional clothing.

First, the user can select the functional clothing course from the course selection part 117 (S1510). As soon as the user selects the functional clothing course, the control piece can start a washing cycle, a rinse cycle and / or a spin cycle sequentially or selectively.

F. 1 Washing Cycle (S1530):

F.1.1 Water supply (S1531):

The control part implements a water supply step of a wash cycle. The water supply step provides the washing water needed to wash clothes. In addition, the water supply step

55/104 dissolves detergent in the washing water provided and wets the clothes placed in the drum.

F.1.1.1 First Water Supply (S1533):

The water supply stage includes a first water supply stage implemented for a predetermined period of time. In the first stage of water supply, the drum can be operated in the turning movement. As mentioned above, the turning motion rotates the drum in a predetermined direction and in a reverse direction alternatively. After being rotated 90 ° or less from the lowest point of the drum in the predetermined direction and in the reverse direction, the clothes may fall. As a result, alternating clockwise / counterclockwise rotation generates a vortex in the washing water and detergent dissolution can be promoted. At the same time, clothes rotated 90 ° or less fall off and a big shock is not applied to the clothes. Because of this, the turning movement in the first water supply step allows the detergent to be dissolved in the washing water and a big shock is not applied to the functional clothes. The turning movement can be repeated for a predetermined period of time, several times.

F.1.1.2 Second Water Supply (S1535):

Once the first water supply has been completed, a second water supply can be implemented for a predetermined period of time. In the second water supply, the washing water is continuously supplied and the filtering movement and turning movement are sequentially implemented. The first and second stages of water supply can be classified according to a pre-established time. The time for each step can be adjusted according to the amount of clothes and other parameters as appropriate. To do this, a laundry quantity determination step configured to determine the laundry quantity can be provided prior to the water supply stage.

As mentioned above, the filtration movement rotates the drum at high speed to generate the centrifugal force and the clothes are in close contact with the internal circumferential surface of the drum due to the centrifugal force. In addition, the washing water passes through the clothes and through the holes in the drum by centrifugal force and is released into the tub. As a result, the clothes are wetted by the washing water in the filtration movement to be washed. In addition, washing water passes through clothing simply and functional clothing may not be damaged by being soaked in

56/104 wash. After the filtering movement is implemented for a predetermined period of time, the turning movement can be implemented. As mentioned above, the detergent can be continuously dissolved without damage to functional clothing. The clothes can be effectively wetted in the washing water by the generated vortex and by extension, the turning movement generates the drum rotation repeated clockwise / counterclockwise. Because of this, rolled clothes can be unrolled before being washed. In addition, the pivoting motion causes the clothes to fall from a relatively low position and damage to the clothing fabrics can be minimized by unrolling the clothes. As a result, the combination of filtration and spin movements can minimize damage to functional clothing and allow wetting of clothing, dissolving detergent and unwinding of clothing to be achieved effectively. Such a sequential combination of the filtering and turning movements can be repeated several times over a predetermined period of time.

F.1.2 Washing (S1540):

Once the wash water is supplied at a predetermined water level, the water supply step is completed and then a wash step can begin. Since functional clothing is relatively light and thin, essentially the same washing step can be implemented, regardless of the amount of clothing in the drum.

F.1.2.1. First Wash (S1541):

The washing step can include a first washing step for a predetermined period of time, with the drum driven in the step movement. As mentioned above, the step movement causes the clothes to fall from the highest position. As a result, the step movement in the first washing step mixes the items of clothing evenly and the washing water preliminarily. In addition, the step movement immerses contaminants from the clothes and shock the clothes to separate the contaminants from the clothes using high rotation / rotation of the clothes.

F.1.2.2. Second Wash (S1543):

After the first washing step, a second washing step can be implemented for a predetermined period of time. In the second washing step, the washing water is heated for washing and removing contaminants more effectively. First, the wash water can be heated by a heater provided on a lower surface of the tub or a steam generating device configured to supply steam to the tub. Substantially, the

57/104 wash water can be heated to approximately 25 ° C to 30 ° C, preferably approximately 27 ° C in the second wash step. Functional clothing is made of fine synthetic fabric texture and can be damaged if the temperature of the heated wash water is too high. As a result, the washing water having an appropriate temperature used in the second washing step can improve the washing efficiency and can prevent damage to the fabrics.

Simultaneously with the heating of the washing water, the drum can be activated in the turning movement in the second washing step. The turning movement 10 uses the falling of the clothes from the relatively low position and the alternative rotation of the drum. Because of this, the clothes can be turned smoothly enough moved in the washing water. The washing water in the turning motion can be heated evenly in a relatively short time and the heat can be transmitted to the clothes sufficiently. In addition, the turning movement 15 can generate shock by the friction between the washing water and the clothes and the shock of falling can remove contaminants effectively without damaging the fabrics.

F.1.2.3. Third Wash (S1545):

After the second washing step, a third washing step can be implemented for a predetermined period of time. In the third washing step, any remaining contaminants can be removed and a combination of turning and step movements can be implemented. Although the spinning motion can remove contaminants without damaging the fabric as mentioned above, the washing capacity is relatively low compared to other movements. As a result, the step movement capable of delivering the strongest shock is added and the washing capacity of the mainly configured washing step from the turning movement to functional clothing can be improved. In addition, the strong shock of the step movement can prevent “balls” from being attached to the clothes. As a result, the third washing step can minimize damage to functional clothing and separate contaminants from clothing completely and effectively.

F.2. Rinse cycle (S1550):

A rinse cycle for the functional clothing course may be similar to the rinse cycle for the courses including the standard course mentioned above and 35 rinse cycles for the other courses to be described later, and therefore further detailed description will be omitted.

58/104

To reinforce the general rinse capacity, the rinse cycle can be repeated more frequently than the rinse cycle of the standard stroke. For example, the rinse cycle can be implemented at least three times or more. This is because the drum is spun at a lower RPM in a spin cycle of the functional clothing stroke than in the standard stroke thus providing weaker rinsing capacity. That is, the spin cycle separates the washing water from the clothes using centrifugal force generated by the high speed rotation of the drum and can provide a rinsing function configured to separate detergent and contaminants together with the washing water of the clothes simultaneously. A normal spinning step of the spinning cycle of the functional clothing stroke uses relatively low RPM of drum rotation and the final rinse capacity may be weakened. Thus, the rinsing step of the rinsing cycle of the functional clothing course can be implemented three times or more.

F. 3 Turn Cycle (S1570):

A turning cycle for the functional clothing stroke may be similar to the turning cycles of the courses including the standard stroke mentioned above and the turning cycles of the other courses to be described later. A normal turning step of the turning cycle can rotate the drum with a lower RPM than the normal turning step of the standard stroke, to prevent damage to clothing.

G. COURSE G (SPEED WASHING COURSE):

A Speed Wash Course G, called “speed wash course capable of washing clothes in a relatively short time, compared to other courses, will be described with reference to FIG. 7B. A small amount of clothing usually requires a substantially short time compared to a large amount of clothing. In the case of a small amount of clothing, an unnecessarily long amount of time can be spent implementing the general wash. Because of this, a course used to wash a small amount of clothing in a short amount of time can be provided. The speed wash stroke is based on the standard stroke described above with respect to FIG. 7, and each cycle or operating conditions for each step in the standard course can be optimized, or a predetermined number of steps can be omitted as appropriate.

First, the user can select the speed wash stroke from the stroke selection part 117 (S710B) and the control part can implement a wash cycle (S730B), a Rinse Cycle (S750B), and

59/104 a Turn Cycle (S770) composing the washing stroke by speed.

G.1 Wash cycle:

G.1.1 Clothes Quantity Determination:

The control piece can start a laundry quantity determination step to determine the laundry quantity (S731B). The laundry quantity determination step can be implemented before a water supply step starts after the user selects the speed wash course. The quantity of laundry measured in the laundry quantity determination step of the standard course as described above can be classified into two categories, namely, a large quantity and a small quantity, to determine the next cycle or drum movement of each stage and other operating conditions. In the speed wash course, the amount of laundry measured can be used to determine the total wash time, that is, the total time taken to complete the wash, rinse and spin cycles. In this case, the amount of laundry can be specified in more categories, for example, three or more categories in the speed wash course. If the amount of laundry is classified into more categories, a different overall washing time (ie the total time spent to complete the wash, rinse and spin cycles) can be established for each of the laundry quantity categories. As a result, the overall washing time can be controlled by matching the amount of laundry. Because of this, a relatively short time can be properly applied to a small amount of laundry without impairing the actual washing capacity.

For example, the amount of laundry to be measured can be classified into three categories including first, second and third categories, or it can be classified into more than three categories. For example, the first category corresponds to a load of less than approximately 1.5 kg and an appropriate washing time of the first category can be established for approximately 25 to 30 minutes, and specifically, 29 minutes. The second category can correspond to a load of approximately 1.5 to 4.0 kg and an appropriate washing time of the second category can be established in approximately 35 to 40 minutes, specifically, 39 minutes. Finally, the third category can correspond to a load of more than approximately 4.0 kg and an adequate washing time for the third category can be 45 to 50 minutes, specifically 49 minutes. Such categories and times can be

60/104 stored in the memory of the control piece as table data.

Since the quantity of clothes is determined in the step of determining the quantity of clothes, the control piece determines which category corresponds to the measured clothes, in reference to the stored categories table. After that, the control piece can establish the washing time given to the category corresponding to the amount of laundry measured as an actual washing time.

G.1.2. Water Supply / Heating / Washing:

After the series of steps above, the control part can sequentially implement a water supply step (S733B), a heating step (S740B) and a wash step (S742B) of the wash cycle (S730B). The water supply step, the heating step and the wash step of the speed wash stroke cycle are similar to those of the standard stroke wash cycle shown in FIG. 7, therefore, an additional detailed description will be omitted.

As mentioned above in the standard course shown in FIG. 7, a heating preparation step configured to promote heating of the washing water can be implemented before a heating step. However, the heating preparation step can be a preliminary step and a drum movement of a predetermined time period can increase the overall washing time. As a result, preliminary steps such as the heating preparation step before the heating step may not be implemented in the speed wash course. After the water supply course, the heating step has yet to start.

G.2 Rinse cycle:

Once the wash cycle is complete, a rinse cycle (S750B) configured to remove detergent remnants and contaminants remaining on clothing can be implemented. The rinse cycle (S750B) is similar to the rinse cycle (S750) of the standard stroke shown in FIG. 7, therefore, an additional detailed description of the rinse cycle will be omitted.

The first rinse step implemented in the initial stage of the standard stroke rinse cycle can include the first step of driving the drum using the time-consuming filtration movement. In contrast, the drum movements implemented in the rinsing steps (S751B, S756B, S760B) require a relatively short time, while still providing the clothes with sufficient rinsing. As a result, the filtration movement of the first

61/104 rinse step provided in the rinse cycle of the speed wash course can be omitted to reduce the overall wash time.

G.3 Turn Cycle:

As soon as the rinse cycle is completed, the control part can start a turning cycle (S770B). The spin cycle of the speed wash stroke is similar to the spin cycle of the standard stroke shown in FIG. 7, therefore, additional detailed description will be omitted.

The unrolling step of the clothes implemented in the initial stage of the spin cycle of the standard course implements a drum movement capable of unrolling the clothes. However, such a drum movement may not affect the turning capacity substantially. Because of this, the unrolling step may not be implemented in the spin cycle of the speed wash course to reduce the overall wash time.

Although the drum in the normal spin stage of the standard stroke can be rotated at approximately 1000 RPM, the drum in a normal spin stage of the speed wash stroke can be rotated at approximately 800 RPM. As the drum rotation speed increases, the drum vibration and noise can become more serious and the preparation steps implemented for the drum to reach target RPM just as the eccentricity measurement step can be repeated to require a relatively long operating time long. As a result, the target rotation speed of the speed wash stroke decreases compared to that of the standard stroke and the accelerating speed time can be prevented from increasing.

As mentioned above, the speed wash course can classify the laundry quantities in specific categories and can establish the appropriate general washing time for each category, so that the general washing time of the large amount of laundry as well as the small amount clothing can be reduced accordingly. In addition, compared to the standard stroke, unnecessary steps can be omitted from the cycles to reduce the overall washing time. However, most drum movements applied to standard stroke cycles are adapted to the speed wash stroke and the wash capacity can be achieved. As a result, the speed wash course can wash a small amount of laundry in a short time, while maintaining washing capacity.

H. COURSE H (SILENT COURSE):

62/104

Course Η will be described with reference to FIG. 16. Stroke H can be referred to as a “silent stroke” capable of reducing noise during washing.

In certain circumstances, less noise from the washing machine may be required by the user. For example, if washing is done at night and / or a baby or child is sleeping, it is preferable that the washing machine operates with less noise. Reduced operating noise can be achieved in several ways. Optimizing a washing control method can effectively reduce noise without increasing production costs. The washing control method configured to reduce such noise can be incorporated by a single stroke, namely, a silent stroke presented by optimization of operating conditions. The silent stroke is based on the standard stroke and is incorporated by optimizing or omitting certain operating conditions for certain cycles or stages of the standard stroke. FIG. 16 is a flow chart of different stages of the silent stroke from the steps of the standard stroke. First, the user can select the silent stroke from the stroke selection part 117 (S1610) and the control part can implement the following series of operations.

H.1 Wash cycle (S1630):

H.1.1 Determination of the Quantity of Clothes (S1631):

The control piece can start a laundry quantity determination step to determine the laundry quantity. The step of determining the amount of laundry was described above and, therefore, a further detailed description of the laundry will be omitted. An object of the silent stroke is to reduce noise and / or vibration while also maintaining washing capacity. A drum drive movement for each stage can be differentiated according to the amount of laundry.

H.1.1. Water Supply (S1633):

As soon as the user selects the silent stroke, the water supply step can begin. The water supply stage supplies washing water to the vat. In addition, the water supply step dissolves detergent mixed with the washing water and wets the laundry placed in the drum. In the water supply stage of the silent stroke, the control piece can supply a larger amount of wash water to the tub, compared to the water supply stage of the standard stroke. The reason why more washing water is provided will be described in a next washing step.

H.1.1.1 First Water Supply (S1635):

63/104

In the water supply step, the control part can implement a first water supply step, together with the wash water supply. In the first stage of water supply, the control part controls the drum to be driven in the rolling motion.

As mentioned above, the rolling motion rotates the drum in a predetermined direction continuously and the laundry is separated from the drum after being rotated to a position of 90 ° or less with respect to the direction of rotation of the drum from the lowest point of the drum. drum. In the rolling motion, the drum is spun at a relatively low speed and the separate laundry is moved by rolling over the inner surface of the drum to the lowest point of the drum, without falling to the lowest point. Because of this, the rotation of the drum and the rolling motion of the laundry can generate a predetermined vortex in the washing water and detergent dissolution can be promoted in the washing water. At the same time, the rolling movement induces the rolling movement of the laundry along the inner surface of the drum and the drum may not have any noise from the shock generated by the sudden falling of the laundry. As a result, the scrolling motion in the first water supply step can allow the detergent to be sufficiently dissolved in the water while also reducing noise. In the first water supply step, the scrolling motion can be repeated for a predetermined period of time a number of times.

H.1.1.2 Second Water Supply (S1637):

As soon as the water supply step is completed, the control piece can start a second water supply step. In the second stage of water supply, the control part can control the drum to be activated in the filtration movement and in the rolling movement sequentially, with washing water supply to the tank continuously. The first and second stages of water supply can be distinguished from each other according to the respective pre-established time and the time of each stage can be adjusted according to the amount of laundry.

As mentioned above, the filtration movement rotates the drum at high speed to generate a centrifugal force and the generated centrifugal force keeps the laundry in close contact with the inner circumferential surface of the drum. In addition, the washing water passes through the laundry and holes in the drum by centrifugal force to be released into the tub. As a result, the laundry is wetted by the washing water in the filtration movement. In addition

64/104 washing water simply passes through the laundry and the laundry may not be damaged while being soaked in the washing water. After the filtering movement has been implemented for a predetermined period of time, the scrolling movement can be implemented. As mentioned above, the scrolling motion in the first water supply step can allow the detergent to be sufficiently dissolved in the wash water while also reducing noise. In addition, a wider surface area of the laundry comes into contact with the washing water, moved by rolling along the inner surface of the drum, so that the laundry can be wetted in the washing water more effectively and evenly. As a result, the combination of filtering and rolling movements can minimize noise and allow wetting of clothes, dissolving detergent and unwinding of clothes to be achieved effectively. Such a sequential combination of filtering and scrolling movements can be repeated several times over a predetermined period of time.

H.1.2 Washing (S1635):

As soon as the wash water is supplied at a predetermined water level, the water supply step is completed and then a wash step can be started.

H.1.2.1 Heating / First Wash Stage (S1640):

As soon as the water supply step is completed, the control part starts a first washing step. The first washing step can include a heating step configured to heat the washing water to a predetermined temperature. Unlike the heating step and the standard stroke wash step, the first silent stroke wash step may include only the scrolling motion. The rolling motion allows the laundry to move by rolling along the inner surface of the drum without suddenly falling. As a result, such a rolling motion can maximize the friction between the laundry and the washing water and between the laundry and the drum and the washing step can remove contaminants from the laundry effectively, with minimized noise.

As mentioned above, the control part in the water supply step can supply a larger amount of wash water, compared to the water supply step of the standard stroke. For example, the control piece can control the amount of wash water supplied in the silent stroke wash step, being 1.2 times the amount of wash water

65/104 wash supplied to the same amount of laundry. The increase in the amount of washing water results in an increase in the water level inside the drum. When the laundry is moved by rolling in the drum with the water level elevated by the rolling motion, the friction between the washing water and the laundry can still increase and the washing capacity can still be improved. Eventually, the scrolling movement adapted in the washing step can provide adequate washing capacity while also suppressing noise generation.

As soon as the predetermined quantity or more of the laundry is placed in the drum, the low speed rotation of the drum cannot easily spin the laundry along with the drum. Even if rotated with the drum, the large amount of laundry may have difficulty being moved by rolling over the inner surface of the drum due to the volume. As a result, since the rolling motion spins the drum at relatively low speed, the large amount of laundry fails to roll as intended and thus does not reach the desired washing capacity. Because of this, if you wash a large amount of laundry, the washing step may adapt a drum movement different from the rolling movement described above.

That is, when the amount of laundry measured in the laundry quantity determination step is greater than a pre-established reference value, the rotating movement may be implemented in the washing step, instead of the rolling movement. The rotating motion rotates the drum in the predetermined direction continuously, similar to the rolling motion, and the speed of rotation of the drum in the rotating motion is greater than that of the drum in the rolling motion. As a result, the laundry is separated from the drum after being rotated 90 ° or more with respect to the direction of rotation of the drum from the lowest point of the drum. As soon as the drum is rotated at a relatively high speed in the rotating motion, the separate laundry falls to the lowest point on the drum and this is different from the rolling motion. As a result, the laundry can be washed with the shock generated by the friction between the laundry and the washing water and the fall. Although the rotating motion generates more noise than the rolling motion, the noise generated may be less than the noise generated in other drum movements such as the step movement and the scrubbing movement which have a strong washing capacity. Because of this, the rotating movement can wash large amounts of laundry effectively, while suppressing noise generation as much as possible. When the quantity of laundry measured is less than the reference value, the movement of

66/104 scrolling can be implemented as mentioned above.

To promote the heating of the wash water, a heating preparation step can be implemented before a heating step. However, the heating preparation step may include a drum movement and the drum movement may generate noise. As a result, the preliminary steps such as the heating preparation step before the first washing step may not be implemented in the washing step of this course and the washing water can be heated to a predetermined temperature in the first washing step. The washing water can be heated by the heater or by the steam generating device installed in the tank.

H. 1.2.2 Second Wash (S1642):

The control piece can start a second washing step after the first washing step. Contaminants can be removed more completely in the second washing step. Like the first washing step, the second washing step of the silent stroke can include only the scrolling motion. Noise generation can be minimized in the rolling motion and contaminants from clothing can be removed effectively in the rolling motion, as described above. In addition, a greater amount of wash water is provided in the scroll movement, compared to the amount of wash water provided in the standard stroke. Because of this, adapting the scrolling motion can ensure sufficient washing capacity while also suppressing noise generation.

If the amount of laundry is large, the drum is driven in the rotating motion. If the amount of laundry is small, the drum is activated in the rolling motion, similar to the first washing step described above.

H.2 Rinsing Cycle (1650):

Once the wash cycle is complete, a rinse cycle configured to remove detergent and contaminant residues from the laundry can start. The rinse cycle is similar to the rinse cycles of the standard stroke described above, so an additional detailed description will be omitted.

The first rinsing step implemented in the initial rinsing cycle of the standard stroke includes the first step of driving the drum using the filtration movement, which can generate a lot of noise. As a result, the filtration movement is not implemented in the rinse cycle of the silent stroke. Although the rinse cycle steps of the standard stroke can

67/104 adopt several drum movements, the silent stroke can apply only the rolling movement to the rinsing cycle steps to reduce noise as in the washing step.

To reinforce the general rinsing capacity, the rinsing steps are repeated more often in the silent stroke than in the standard stroke. For example, the rinse cycle can be implemented four times or more. This is because the drum is rotated with a lower RPM in the silent stroke rotation than in the standard stroke rotation cycle, thus deteriorating the rinsing capacity. That is, in the spin cycle, the washing water is typically separated from the laundry by the centrifugal force generated by the high speed rotation of the drum and the detergent and contaminants are separated from the laundry together with the washing water simultaneously. However, in the normal turning step of the turning stroke of the silent stroke, the drum is turned at a lower RPM and thus the final rinsing capacity may be impaired. As a result, the rinsing steps can be implemented four times or more in the rinse cycle of the silent stroke.

H. 3 Turn Cycle (S1670):

As soon as the rinse cycle is completed, the control piece can start a turning cycle. The turning cycle is similar to the turning cycle of the standard stroke, therefore, an additional detailed description will be omitted.

In a normal turning step of the silent stroke, the drum can be turned at a lower RPM than in the normal turning step of the standard stroke to reduce noise. For example, the drum can be rotated at a predetermined RPM which is 50% of the RPM of the normal running cycle of the standard stroke. That is, the drum can be rotated at approximately 400 RPM.

I. COURSE I (COTTON MIXTURES, SYNTHETIC COURSES)

Like the functional clothing course described above, courses corresponding to the types of clothing items and the types of fabrics in the laundry to be washed can be provided. For example, a cotton course configured to wash cotton fabric such as towels, tablecloths, shirts and the like, a synthetic course or easy care course for washing synthetic fabric, and a mixing course configured to wash one can be provided. mixture of fabric types such as cotton and synthetic fabrics. The synthetic material can include, for example, polyamide, acrylic, polyester and other fabrics.

Cotton fabric and synthetic fabric have different characteristics. That is, the cotton fabric is more resistant to friction and shock, with less concern about deformity, than synthetic fabric. In addition, the

68/104 cotton fabric can absorb more washing water than synthetic fabric and is less prone to wrinkles than synthetic fabric. However, it is not easy to separate cotton fabric clothing items from synthetic fabric clothing items and implement corresponding washing courses to wash them separately all the time. This is because the user usually wears clothes made from cotton and synthetic fabric together, and does not want to wash separate partial loads of cotton and synthetic clothing. As a result, a washing course that combines the merits of the cotton course and the synthetic course, ie a mixing course, can be provided.

The mixing stroke can be useful for many reasons. For example, if the user separates cotton fabric clothing items and synthetic fabric clothing items to wash them separately, washing can be disadvantageously delayed until a predetermined amount of clothing is put on, and thus contaminated clothing can be neglected for a long time. Obviously, if a small amount of laundry is washed separately, energy can be wasted. Because of this, the mixing course capable of washing conventional types of fabric clothing items together can prevent the problem of neglecting clothing and expending energy.

In the wash course provided corresponding to such fabric mixtures shown in FIG. 17, a wash cycle, a rinse cycle and a spin cycle can be differentiated according to the characteristics of the specific type of fabric. As follows, the cotton stroke, synthetic stroke and mixing stroke having operating conditions for each step adjusted based on the type of fabric will be described with reference to the cycles and standard stroke steps described above. In comparison to the standard course, repeated detailed description will be omitted as appropriate and the difference will be described in detail.

As soon as the user selects the cotton thread, the synthetic thread or the mixing thread (S1710) according to the type of clothing fabric, the control piece can implement a washing cycle (S1730), a rinse cycle ( S1750), and a turning cycle (S1770) and steps according to the selected stroke.

1.1 Wash cycle:

1.1.1 Clothes Quantity Determination Stage (S1734):

The control piece can determine the amount of laundry in a wash cycle and a method of determining laundry amount in this course is similar to the above methods and repeated description will be omitted. The amount of clothing measured can be used in a next step properly, which

69/104 will be described in detail.

1.1.2. Water Supply Stage (S1733):

The control piece can implement a water supply step configured to supply water and detergent to the tub or drum and to dissolve the detergent in the wash water. That is, the washing water is supplied from an external water supply source, along with the detergent. To supply the water and detergent to the laundry initially, the washing water and detergent are supplied to the laundry inside the drum directly. That is, a water supply for the washing water can be located in an upper front portion of the drum towards the drum, not in a lower portion of the tank. When the detergent is of the powder type, the dissolution of the detergent fails to be sufficiently implemented and a drum triggering step of the water supply step, which will be described later, can dissolve the detergent sufficiently. As a result, washing water and detergent are supplied to the laundry at the initial stage of the washing cycle and the time required by the washing cycle can be reduced to improve washing efficiency.

1.1.2.1 Promotion of Detergent Dissolution (S1735):

In a detergent dissolution promotion step, a drum drive movement can be differentiated according to the type of clothing fabric. For example, the scrubbing movement can be implemented for cotton fabric clothing items and the step movement can be implemented for synthetic fabric clothing items. In alternative modalities, the rubbing movement and / or step movement can be implemented.

The rubbing movement bends / stretches and rubs the clothing, dropping it, to generate friction. Because of this, a rubbing effect similar to human hands can be expected in the initial stage of the wash cycle. However, this rubbing movement can be implemented for fabrics that are somehow resistant to friction and the drum drive movement can be the rubbing movement in the detergent dissolution step of the cotton course.

According to the characteristics of the synthetic fabric, synthetic clothing items are lighter than cotton clothing items and synthetic clothing items have a lower percentage of water than cotton clothing items. In addition, synthetic clothing items

70/104

In addition, synthetic clothing items are more concerned with friction damage than cotton clothing items. Because of this, the step movement can be implemented in the detergent dissolution promotion step to promote detergent dissolution and prevent tissue damage. In other words, a drum drive movement in a step to promote detergent dissolution for the synthetic fabric can be the step movement. The step movement applies the maximum drop shock to the synthetic fabric to promote detergent dissolution and the effect of the washing effect similar to the human touch can be expected in the initial stage of the washing cycle.

A drum drive movement of a detergent dissolving promotion step in the mixing stroke can be the combination of the step movement and the scrubbing movement. That is, the step movement and the scrubbing movement, which are ideal for cotton fabric and synthetic fabric, can be combined so that detergent dissolution can be promoted and the washing effect can be expected in the initial stage. the wash cycle. In this case, the drum drive movements are combined and because of this the patterns of movement of clothes and patterns of movement of washing water can be diverse enough to improve the effectiveness of the washing cycle.

1.1.2.2 Clothes Wetting (S1736):

In the wetting step of the standard stroke, the drum can be rotated in the rolling motion. The rolling motion generates less friction applied to the laundry than the scrubbing motion and the rolling motion is implemented in a period with the wetting of the laundry implemented. As a result, although friction is applied between items of wet clothing, there will be little concern about damage to clothing and the wetting step of the clothing implemented in the scrolling movement can be implemented similarly, regardless of the types of clothing fabric.

Regardless of whether the fabric is cotton or synthetic, the scrolling movement can be implemented in the wetting of the clothes. Even when the user selects any of the cotton strokes, mixing strokes or synthetic strokes, the scrolling movement can be implemented in the laundry wetting step after the detergent dissolution promotion step.

The laundry wetting step can include two steps including first and second laundry wetting steps which are implemented separately.

71/104

For example, when the wetting step is implemented for 10 minutes, the first wetting step for the laundry can be implemented for 5 minutes and the second wetting step for the laundry can be implemented for 5 minutes. Specifically, the additional water supply can be implemented in the first wetting step and the second wetting step can be implemented once the additional water supply is completed.

The drum drive movements of the first and second clothes wetting stages can be differentiated to look more effectively at the clothes and to provide both detergent and washing water to the clothes evenly. For example, the drum drive movement of the first laundry wetting step may be the rolling movement and the drum driving movement of the second laundry wetting step may be a combination of the rolling movement and the filtration movement. In other words, the rolling movement can be implemented in a predetermined net performance ratio in the first stage of wetting the laundry. In the second stage of wetting the laundry, after the filtration movement is implemented once, the rolling movement is implemented four times and this makes up a single cycle. The cycle can be repeated.

The rolling motion continuously reverses the laundry on the bottom of the drum to increase the connection time between the washing water and the detergent. The filtration movement spreads the laundry widely and allows washing water and detergent to be supplied to the laundry evenly, so that effective wetting of the laundry can be possible. It can take approximately 13 minutes to complete the wetting of the laundry in the rotating motion, while the wetting of the laundry may take approximately 10 minutes according to this modality.

The actuation movement of the first wetting step can be differentiated according to the amount of laundry. The drum drive movement of the first laundry wetting stage can be differentiated according to the laundry quantity determined in the laundry quantity determination step. For example, if the amount of laundry determined is a predetermined level or more, the drum is driven in the rolling motion as mentioned above. If the amount of clothing determined is less than the predetermined level, the drum can be operated in a combination of step and roll movements.

72/104

The step movement suddenly drops the clothes after lifting. If the amount of clothing is large, the distance from which the clothing can fall can be reduced. Thus, the step movement is suitable for a small amount of clothing. Such step movement can cause damage to the clothing. As a result, in the cotton course, when the amount of laundry is less than the predetermined level, the combination of step movement and rolling movement can be implemented in the first step of wetting the laundry. When the amount of laundry is the predetermined level or more, the rolling movement can be implemented in the first wetting step. In the synthetic cotton course and in the mixing course with the concern for damage to the clothes, the scrolling movement can be implemented in the first step of wetting the clothes, regardless of the amount of clothes.

In alternative modalities, a circulation stage can be implemented in the water supply stage, in relation to the movement of the drum. In other words, the circulation step can be synchronized with the motor drive configured to drive the drum. The washing water circulated when the laundry is moved by the drum drive can be supplied to the laundry and the object of the water supply step can be raised more effectively.

The detergent dissolution promotion step and the laundry wetting step are included in the water supply step according to this modality. However, the detergent dissolution promotion step and the laundry wetting step could be provided independently of the water supply step. In this case, after the water supply, the detergent dissolution promotion step or the laundry wetting step can be implemented.

1.1.3. Heating (S1741):

A heating step can be differentiated according to the operating course selected in this course. For example, the wash water temperature used in the heating step can be set differently depending on the type of fabric of the garment.

The fabric is cotton is somehow tolerant to heat. As the temperature of the washing water increases, the more detergent is dissolved in the washing water the more activation of the detergent is promoted. As a result, when the cotton stroke is selected, the wash water temperature can be set at approximately 60 ° C in the heating step. Such washing water temperature can be selected from a range that

73/104 extends from cold water to water at approximately 95 ° C through option selection piece 118. As the wash water temperature increases, detergent activation can be further promoted and washing capacity improved, further improving a sterilizing / bleaching effect, if appropriate.

Synthetic fabric may be more subject to less heat tolerance and thus the synthetic course or course of objective mixing will prevent heat from damaging clothing. When the synthetic or mixing stroke is selected, the wash water temperature can be set at approximately 40 ° C in the heating step. In the synthetic course or mixture of courses, the user can prevent the selection of the wash water temperature from exceeding 60 ° C, to avoid damage to the clothes. For example, when the synthetic stroke or the mixing stroke is selected, the temperature of the washing water in the heating step may have the upper limit of 60 ° C.

A driving movement of the drum of the heating step can be the rotating movement, regardless of the selected stroke. This is because the rotating movement can separate the clothing, reducing damage to the clothing. As a result, the rotating motion can allow steam or heated wash water to be sufficiently transmitted to the laundry.

In alternative modalities, a circulation step can be implemented in the heating step. The circulation step can be synchronized with the driving of the drum. As the circulation step is implemented after the initial heating is implemented to a predetermined degree, the circulation step can be synchronized with the conduction of the drum at a predetermined time after the initial conduction of the drum begins.

1.1.4 Washing (S1742):

A driving movement of the drum of a washing step can be a sequential combination of the rolling motion and / or rotating motion and / or oscillating motion. The driving movement of the drum in the washing step can be differentiated according to the selected stroke, because both the protective effect of the fabric and the effect of the improved washing capacity must be achieved.

That is, in the case of washing cotton fabrics, a driving movement of the drum configured to wash clothes using a great mechanical force can be implemented. In the case of washing synthetic fabric, a movement

74/104 drum drive configured to wash clothes using relatively low mechanical strength can be implemented. The washing step can include one of the washing cycle steps, which requires more time. As a result, the washing step can be controlled to implement the washing more efficiently. Since the time required for the washing step is long, it is likely that most of the damage to the clothes will be generated in the washing step.

Whereas the drum can be driven in combination with the rolling movement and the rotating movement in the washing step when the cotton stroke is selected. The combination of the two different movements applies various patterns of strong mechanical strength to the laundry and the washing efficiency can be improved. That is, according to the characteristics of the cotton fabric, there is little concern for damage to the fabric. Because of this, strong mechanical force is applied to washing clothes and the washing effect can be improved. When the cotton stroke is selected, a combination of the filtering movement and the rotating movement can be implemented in a washing step, with the circulation step synchronized with the drum driving. Since the cotton fabric offers little concern for damage to clothes, the filtration movement can provide washing water and laundry detergent continuously and effectively.

In contrast, when the synthetic stroke is selected, the drum can be rotated in a combination of oscillating and rotating motion in the washing step. The combination of the two different movements can improve the washing effect. The oscillating movement gently sways the laundry in the washing water and therefore the damage caused by friction can be minimized. In addition, the time that the laundry stays in contact with the washing water can be increased enough to improve the washing effect.

As the mixing stroke is provided to wash the cotton garments and synthetic garments together effectively, the washing effect must be improved and the damage to the garments must be reduced as much as possible, regardless of the type of fabric. clothes. To satisfy this aspect, the driving movement of the drum of the washing step, when the mixing stroke is selected, can be a combination of the rotating motion and / or oscillating motion and / or rolling motion. That is, the oscillating movement configured to prevent wear of the fabric can be provided and the rolling movement configured to improve the washing capacity

75/104 can be provided.

In the synthetic and mixing courses, a circulation step can be synchronized with the drum conduction to allow washing water and detergent to be supplied to the laundry continuously.

As mentioned above, although one of the cotton stroke, synthetic stroke, or mixing stroke is selected, the driving movements of the washing step drum can be controlled by a combination of two different movements. This is done to generate various patterns of mechanical strength and movement of clothing and to improve user satisfaction visually.

When a level of contaminant in the laundry is selected from option selection piece 118, the net action ratio of the engine can be adjusted according to the level of contaminant selected. However, increasing the net action ratio also increases the time that mechanical force is applied to clothing. Considering that the ratio of net action of the washing cycle can be differentiated according to the stroke selected by the user. That is, the net action ratio of the course to cotton may be greater than that of the course to synthetics and the course of mixing.

1.1.2 Rinse cycle (S1750):

Once the wash cycle is completed, a rinse cycle can begin. In the rinse cycle, rinse steps configured to drain the wash water after the laundry is rinsed using the wash water provided can be repeated. The rinse step of the rinse cycle in this course can be repeated three times or more.

The wash water can be supplied at a water level in the rinse cycle to be greater than a water level in the wash cycle. That is, the washing water can be supplied at a predetermined level of water that is visible from the outside to improve the rinsing effect using sufficient washing water.

A driving motion of the rinse cycle drum may be the rotating motion. The rotating motion submerges / removes the laundry in / from the wash water and this can be repeated. The high water level in conjunction with the rotating movement visually notifies the user of sufficient rinsing. The rotating movement of the rinse cycle can prevent the engine from overheating, as well as improving washing efficiency. That is, the water level of the rinse cycle can be higher than that of the wash cycle and the load applied to the

76/104 drum can be increased by washing water accordingly. The stepwise movement, the frictional movement and the oscillating movement repeat the centrifugation and the motor brake. As a result, this brake can generate an excessive load on the engine. In addition, if the water level is high, the load generated by the washing water can be increased. In the rinsing cycle with a high water level, the driving motion of the drum does not have a sudden brake to prevent the engine from overheating. Thus, the rotating movement configured to rotate the drum in the predetermined direction may be preferable in the rinse cycle.

A circulation step can be implemented in the rinse cycle to circulate the washing water kept in the tub inside the drum. This can generate a visual notification effect for the user of sufficient rinsing.

I. 3. Rotation Cycle (S1770):

Once the wash cycle and the rinse cycle are completed, a spin cycle configured to remove washing water from clothing as much as possible can be implemented. In a normal stage of the centrifugation cycle, the drum RPM can be differentiated according to the stroke selected by the user, considering the percentage of residual water content and wrinkling according to the type of fabric.

The cotton fabric has a high percentage of water content or absorption, with less worry of wrinkles. Even if there are wrinkles generated in the cotton fabric, it is easy to remove. In contrast, synthetic fabric has a low percentage of water content or absorption, with great concern for wrinkles. As a result, in the cotton course, a pre-defined RPM can be higher than in the synthetic and blending course, and the pre-defined RPM can be, for example, 1,000 RPM or more. Here, the centrifuge RPM can be changeable through the user option selection part.

The pre-set RPM of the synthetic and mixing strokes can be set to be 400 to 600 RPM. Even when spinning synthetic garments at a low RPM, washing water can be removed from synthetic garments sufficiently and wrinkles can be prevented. In this case, the centrifuge RPM can be changeable through the option selection part by the user. In certain embodiments, the spin RPM is set to a maximum of 800 RPM.

J. COURSE J (WOOL COURSE):

A washing course provided according to a type of fabric of the garment can also include a course for wool instead of the course for cotton, course for

77/104 synthetic and mixing stroke. The wool course is applied to clothes with less contaminants and a great concern with the wear of the fabrics. That is, the wool course can be provided to wash woolen clothing items that are hand washable. If washed using strong mechanical force, woolen garments are liable to be damaged. As a result, in the wool course the drum is driven in a predetermined movement having a weak mechanical force, for example, the oscillating movement. Considering the characteristics of the woolen fabric, drum driving movements, washing cycle, rinse cycle and centrifugation cycle of the wool stroke, they can be different from the drum movement of the normal stroke.

J.1. Wash cycle:

In the wool course, it is important to prevent damage to the fabric and the drum can be driven in the oscillating motion configured to move the laundry right and left in a lower portion of the drum gently, in a course wash cycle for wool. In this case, a water level may be high enough to allow a water level inside the drum to be visible from the outside. Because of this, the friction between the inner circumferential surface of the drum and the laundry can be minimized and the touch of the laundry can be repeated, by rotating the laundry submerged in the washing water, and this prevents damage to the laundry and allows washing or washing. rinsing are implemented smoothly. This oscillating movement can minimize damage to the clothes and increase the time of contact with the washing water and the detergent with the clothes to improve the washing effect.

The course for wool is shown in FIG. 18. A stroke wash cycle for wool is selected (S1810). In an initial stage of the washing cycle (S1830), washing water and detergent can be supplied to the tub or drum, that is, a water supply stage (S1833) can be implemented. The water supply step can include a detergent dissolving step (S1835) and a wetting step (S1836). The detergent dissolution step is configured to promote the detergent dissolution implemented in an initial phase of the water supply step and the wetting step is configured to wet the laundry enough to prepare a washing step after supplying water to be completed. The wetting step can be implemented after, or before, the water supply is completed.

The detergent used in the wool course can be neutral detergent and,

78/104 normally, a liquid type that may not require much time to dissolve in the wash water, like a powder type. Considering that the detergent is supplied to the clothes in the initial stage of the water supply, together with the washing water. Once the water supply begins, the washing water is supplied to the liquid detergent kept in a detergent box. Washing water and liquid detergent are supplied together to the tub or drum. To provide the washing water and liquid laundry detergent faster, the washing water and liquid detergent mixed with each other can be sprayed on the laundry located in the drum. For a more effective dissolution of the detergent, a circulation step configured to supply the washing water kept in the tub to the top of the drum can be implemented.

The drum can be driven in an oscillating motion and then a light swirl is generated in the washing water in such a way that the dissolution of the detergent can be promoted and, at the same time, prevent damage to the laundry. Once the water supply is complete, the oscillating movement and the circulation step can be implemented together to prepare for the washing step. This can be considered a type of wetting step.

Once the detergent dissolution step and the wetting step are complete, a heating step (S1841) configured to heat the wash water can be implemented, if necessary. However, the temperature of the washing water in the heating step can be controlled not to exceed 40 ° C. The heat generated if the wash water temperature is too high will deform the laundry and damage the woolen fabric. The temperature of 40 ° C does not generate any thermal deformity and promotes the activation of the detergent and the absorption of washing water in the laundry.

A driving movement of the washing step drum (S1842) can be the oscillating movement. The washing step requires more time outside the washing cycle steps and, in order to avoid damage to the clothes in the washing step, the rotation movement is used in the washing step. If the application and stop of mechanical force are applied to woolen fabric clothes repeatedly, wear and tear on the fabrics can be generated. This mechanical repetition causes contraction of the woolen fabric. To avoid contraction, the oscillating movement can be implemented in the washing step continuously.

As mentioned above, the oscillating motion drives the drum using dynamic braking and cannot apply too much load to the engine. In addition, the

79/104 oscillating movement can have the drum conduction configured to switch between right and left below 90 ° C. As a result, a large load is not required to lift the laundry. If the drum was to be driven in the frictional motion and in the continuous step motion, excessive load may be applied to the engine. In the rotating movement, a lower load can be applied to the motor than in the friction movement and in the step movement, but the suit is lifted and released to damage the fabric. Considering this, the oscillating movement is implemented in the washing step.

J.2 Rinsing cycle (S1850):

Once the wash cycle is completed, a rinse cycle can be implemented. First, a medium spin can be implemented. After the medium turn, the washing water is supplied to start the rinse and the rinse cycle is implemented several times, if necessary. That is, after water supply and rinsing, water drainage can be repeated. Normally, the average rotation is implemented in the middle of the water supply, after draining the water.

The average spin untangles the laundry at a relatively low rotation speed. The average spin includes an intermediate spin configured to untangle the laundry at a relatively low rotation speed while feeling the vibration, and a main spin configured to spin the laundry at a relatively high spin speed for a predetermined time. The intermediate swing can be applied at approximately 100 RPM and the main swing can be applied at approximately 200 RPM (low resonance frequency) or more.

However, when the wool course is selected, the average spin can be omitted. The average spin is a process of removing the washing water from the laundry by centrifugal force and a tractive force can be generated in the laundry inevitably. Because of this, woolen clothing that is subject to external force may be subject to damage in the spin cycle. To minimize such concern, the average turn can be omitted. For example, the main turn of the middle turn is omitted and only the intermediate turn can be implemented. If the entire process of removing the washing water by centrifugal force is omitted, the rinsing capacity can be noticeably deteriorated. Considering the rinsing capacity and the damage to the clothes, only the intermediate swing can be implemented and the main swing can be omitted.

80/104

The rinse step series, including water supply and withdrawal, can be implemented three times or more, because the detergent remains must be completely removed from the laundry. The rinse water level can be higher than the water level of the wash step and a circulation step can be implemented in the rinse. When liquid detergent is used, it is usually possible to remove the detergent remnants sufficiently, because the washing step is implemented twice and due to the average spin. However, in the case of this stroke, the main turning of the middle turning is omitted to avoid damage to the laundry and the rinsing step can be implemented three times to achieve the desired rinsing effect.

Driving the drum of the washing step can be the oscillating motion to prevent damage to the laundry. The oscillating movement slightly sways the laundry in the washing water and allows the detergent residues absorbed in the laundry to be removed into the washing water, so that the rinsing efficiency can be increased.

J. 3 Spin cycle (S1870):

Once the rinse cycle is completed, a spin cycle can begin. The spin cycle is similar to the standard stroke spin cycle described above. The drum RPM of the normal spin stage can be set to be 800 RPM or less, to protect the woolen fabric of the garment.

K. COURSE K (DELICATE COURSE):

A washing stroke provided according to the type of fabric of the garment may include a delicate stroke, as shown in FIG. 19 for washing items made of delicate fabric, such as silk, plastic fabric, items with metal accessories and other delicate items. A drum movement with a relatively weak mechanical force, for example, the oscillating movement, can be implemented to wash delicate clothing gently in the delicate stroke, similar to the wool stroke. As a result, taking the characteristics of the delicate fabric into consideration, the drum driving movements of a washing cycle, a rinse cycle and a delicate stroke centrifuge cycle can be different from the drum driving movements of the standard stroke.

K.1 Wash cycle (S1930):

Similar to the wool stroke, the delicate stroke is selected (S1910) and the drum is driven in an oscillating motion in a washing cycle (S1930) of the

81/104 delicate stroke and wash water is provided (S1933) at a relatively high water level. In addition, a detergent dissolving step (S1935) can be similar to the detergent dissolving step of the wool course, because liquid type detergent is generally used to wash delicate fabric garments in the delicate course, as in the course for there. However, after the detergent dissolution step, a wetting step (S1936) can be different from the wetting step of the wool course. Wool fabric has relatively good water absorption capacity compared to delicate fabric, and delicate fabric is more prone to heat damage compared to wool fabric. Because of this, the temperature of the washing water used to wash the delicate fabric can be set to approximately 30 ° C. Although cold water can be selected, a temperature above 40 ° C is generally not selected.

The wetting step can be implemented effectively using the filtration movement in the wetting step. A circulation step can also be implemented. After the drum has been rotated and the laundry is evenly distributed inside the drum to increase the surface area of the laundry, the circulation step circulates the washing water kept in the laundry tub. In addition, the oscillating movement is implemented to submerge the laundry in the washing water and to generate smooth laundry movement to wet the laundry. The filtering movement and the oscillating movement are repeated in various patterns to wet the laundry. However, the driving motion of the drum of the wetting step may be only the oscillating motion.

Once the wetting of the laundry is completed, a washing step can begin (S1942). A movement of the drum of the washing step can be the oscillating movement. Delicate fabric can be more resistant to external shock compared to wool fabric. To achieve greater washing efficiency, the drum movement of the washing step can be a combination of the oscillating and the rotating movement, with a relatively high level of washing water.

Alternatively, only the rotating movement can be implemented in the washing step. In this case, the falling clothing is bumped against the surface of the washing water, not the bottom inner surface of the drum, because of the high water level. This means that the fall distance is reduced. While the shock applied to clothing is reduced by the high water level, a whirlwind is generated

82/104 in the washing water to improve the washing effect. Since such clothing has relatively low contamination, the washing step time can be configured to be relatively short and the liquid action ratio can be configured to be relatively low. Although only the rotating movement is implemented, it is possible to avoid damage to the clothes. A circulation step can also be implemented in the washing step.

K.2 Rinsing cycle (S1950):

Once the wash cycle is completed, a rinse cycle can begin. As mentioned above, the liquid type detergent can be used in the delicate stroke and detergent remnants can be removed sufficiently by the rinsing step implemented twice. Like the wool stroke, a medium spin can be omitted in the delicate stroke. For example, an intermediate spin is not omitted and only a main spin can be omitted. A movement of the rinse cycle drum can be just the rotating movement. This rotating movement has the effect of distributing the laundry. In other words, the rotating movement allows the surface area of the clothing to come into uniform contact with the washing water and remove detergent remnants. In this case, a wash water level can be relatively high. The oscillating motion can be added to the rotating motion in the rinse cycle.

K. 3 Spin cycle (S1970):

Once the rinse cycle is complete, a spin cycle can begin. The centrifugation cycle of this stroke can be similar to that of the wool stroke. The drum RPM of a normal spin stage can be set to not exceed 800 RPM. The delicate fabric has a low percentage of water / absorption content and the washing water can be removed sufficiently even when the drum is turned at a relatively low RPM in the normal step. In addition, normal spin can be implemented at a relatively low RPM to prevent tissue damage generated by centrifugation.

L. COURSE L (COURSE FOR SPORTS CLOTHING):

A course for sportswear shown in FIG. 2D can be provided in the washing course classified based on the type of fabric of the laundry will now be described. The course for sports clothing can be provided to wash clothes made of functional fabric with good air permeability and good perspiration absorption, such as mountaineering, running and sports clothing in general. Like the wool stroke or the delicate stroke, a drum movement with a

83/104 weak mechanical strength, for example, oscillating movement, can be implemented in the course for sportswear. Because of this, considering the characteristics of the sports fabric, washing drum movements, rinsing and spinning cycles provided in the sportswear course may differ from the drum movements of the standard course. Once the sportswear course is selected (S2010), the wash cycle (S2030), the rinse cycle (S2050) and the spin cycle (S2070) can be implemented as the wool course and the delicate course. However, due to the characteristics of sportswear, the wash cycle for the sportswear course may differ from the wash cycle for the other courses described above.

L.1 Wash cycle (S2030):

Sportswear has hydrophobic characteristics that prevent moisture from penetrating the fabric easily. As a result, compared to other types of fabrics, the sports fabric has a low percentage of water content / absorption and therefore water can be supplied to the sports fabric sufficiently and continuously in the wash cycle. For this purpose, a driving movement of the washing cycle drum (S2030), especially a water supply step (S2033) provided in the washing cycle, may be different from the movement of the washing cycle drum in the other strokes.

First, in this course, a driving motion of the drum of a detergent dissolving step (S2035) can be the friction movement and / or the step movement. Sports fabric generates little concern for fabric damage compared to wool or delicate fabric, so the course for sports clothing can use the driving motion of the drum capable of applying a stronger mechanical force than the oscillating movement.

A wetting step (S2036) of the sportswear course may differ from the woolen course and the delicate course. Although it can prevent damage to clothing, the oscillating movement does not provide enough washing water to a folded part of clothing, due to the hydrophobic characteristics of the sports fabric. Considering this, the filtration movement (including a circulation step) can be implemented at the wetting stage of the course for sportswear. The filtration movement distributes the laundry inside the drum evenly and supplies the washing water to the laundry evenly. Along with the filtration movement, the rolling movement configured to turn the laundry continuously can be implemented.

L.2 Rinsing cycle (S2050):

84/104

A rinse cycle for this stroke can be similar to the rinse cycles for the standard stroke, wool stroke and delicate stroke, so the detailed description of the stroke will be omitted.

L. 3 Spin cycle (S2070):

A centrifugation cycle for this stroke can be similar to the rinsing cycles for the standard stroke, wool stroke and delicate stroke, and thus its detailed description will be omitted.

M. COURSE M:

In the washing machine according to the second embodiment described above with respect to FIG. 2, the bowl is directly attached to the cabinet and the drum is provided in the bowl. According to the second mode, the bowl is fixed and only the drum vibrates. As a result, it is important to prevent the drum from coming into contact with the bowl when the drum is turned and the distance between the bowl and the drum may be greater than the distance in the washing machine, according to the first modality shown in FIG . 1.

When the distance between the bowl and the drum is large, the laundry loaded in the drum cannot be sufficiently wetted by the washing water provided inside the bowl. Because of this, when water is supplied to the washing machine according to the second mode, a circulation pump is put into operation to efficiently wet the laundry and the washing water supplied to the tub can be circulated. For example, the circulation pump can be driven continuously or at a predetermined interval, with the water supply valve being opened.

In the washing machine according to the second mode, the drum is connected to the back of the bowl 230. However, the back of the bowl 230 is supported by the suspension unit through the bearing 400, not the bowl. Because of this, compared to the washing machine according to the first mode, which includes the back of the tub directly connected to the tub to support the drum load, the degree of freedom of the drum provided in the washing machine according to the The first mode can be relatively large and the front part of the drum can have a greater degree of freedom.

However, when water is supplied to the tub, a water supply line and a circulation line are used to supply the wash water from the front of the tub. As a result, the laundry located on the front of the drum would be wet first and the load on the front of the drum is greater than the load on the rear. This can cause the

85/104 front of the drum move down. If the front of the drum moves downward, noise and vibration may increase during drum rotation and may cause the drum to come into contact with the inner surface of the bowl. As a result, in the washing machine according to the second mode, the laundry located on the front and rear of the drum must be evenly wetted when water is supplied to the laundry. Stroke M is referred to as a washing stroke applicable to the washing machine according to the second modality, that is, a standard washing machine stroke according to the second modality. This course will be described with reference to Fig. 21.

M.1 Wash cycle (S2130):

FIG. 21 is a flowchart of Course M. When the user selects this from the course selector part (S2110), the control part can implement the following series of processes.

The washing cycle can include a step determining the amount of laundry (S2131), a water supply step (S2133), a wetting step (S2135), a heating step (S2137) and a washing step ( S2139). In the following description, the wetting step is described as an independent step, separate from the water supply step. However, the wetting step can be included in the water supply step.

M.1.1 Water supply (S2133):

After detecting the amount of laundry in the wash cycle, a water supply step can begin. A clothing-determining step of the water supply step is described in detail in the courses above and therefore the detailed description will be omitted.

The control part supplies washing water to the inside of the bowl at the water supply stage. Specifically, the control part opens the water supply valve to supply wash water to the tub via the water supply line and the detergent box. In the following way, when the washing water is supplied to the clothes in the washing machine according to the second mode, modalities of water supply methods capable of wetting the clothes located in the front and rear of the drum will be described uniformly.

According to a water supply method according to a first modality, when the water supply step provides water, the

86/104 circulation pump is put into operation to circulate the washing water and the drum is put into operation simultaneously. The control part can drive the drum in the frictional movement of the drum movements described above.

In the washing machine according to the second mode, the distance between the drum and the bowl is greater than the distance between the bowl and the drum in the first mode. Thus, in the second mode, if the drum is activated in the rotating movement (as in the first mode) during the water supply stage, the laundry located at the rear of the drum does not get wet evenly. That is, as the gap between the drum and the bowl is larger, the washing water between the drum and the bowl is not raised by the rotation of the drum in the rotating motion and, mainly, the laundry located at the rear of the drum does not get wet .

As a result, in the water supply stage of this course, the friction movement is implemented, instead of the rotating movement. As mentioned above, the friction movement rotates the drum at a higher RPM (compared to the rotating movement) and the washing water located between the drum and the bowl can be lifted by rotating the drum and then poured over the laundry.

In particular, if the rear of the drum and the tub are tilted downwards in the washing machine according to the second mode, the washing water located at the rear of the tub can be supplied to the surface area of the laundry by the friction movement . The frictional movement turns the drum clockwise / counterclockwise, suddenly reversing the direction of rotation. As a result, the sudden reversal of drum rotation causes a swirl in the washing water and the laundry located on the front and rear of the drum can be evenly wetted.

When the water supply valve is open to supply the washing water, the drum is driven and rotated and the laundry is moved inside the drum according to the drum's conduction. In this case, the washing water supplied through the water supply line connected to the front of the drum can be supplied mainly for laundry moved on the front of the drum. The clothes located on the front of the drum are wet beforehand, compared to the clothes located on the back of the drum. As a result, according to the second mode of the water supply method, the drum cannot be driven until a predetermined time has passed.

87/104 after the water supply valve is opened to supply water, or until the water level reaches a predetermined level. When the drum is not driven for the predetermined time, or until the washing water reaches the predetermined level, the washing water supplied through the water supply line can be kept at the bottom of the bowl. The predetermined water level can be determined taking into account the difference between the bowl and the drum and the predetermined time can be determined according to the capacity of the bowl and the drum and the amount of laundry.

In particular, if the rear of the tub supplied in the washing machine according to the second mode is tilted downwards, the washing water can be collected at the rear of the tub. Thus, after passing a predetermined time, the drum is activated and rotated and the washing water kept at the rear of the tub can wet the laundry located at the rear of the drum evenly. When the drum is operated in the washing machine according to the second mode, a movement of the drum can be the rotating or the frictional movement.

When the water supply valve is open for the water supply according to the second mode, without operating the drum, the on / off action of the water supply valve can be controlled. That is, when the water supply valve is open to supply the water, the wash water may have a predetermined pressure, because of the pressure from an external water supply source, such as a tap and then the tap water. washing provided along the water supply line can be supplied to the front of the drum by water pressure, such that the laundry located on the front of the drum can be wetted first.

As a result, during water supply in the second mode, the water supply valve is controlled several times to be switched on and off, not open continuously, and then the wash water supplied can be controlled to be switched on and off to have a predetermined water pressure sufficient not to be supplied directly to the drum. Sufficient pressure not to be supplied directly to the drum means a water pressure that allows the water supplied through the water supply line to fall along the drum, tub or door to be collected at the bottom of the tub, not sprayed on the drum directly . The water that falls along the drum, vat or door can be collected at the rear of the vat and the description of the wash water collected in the vat is similar to the second mode, such that the

88/104 repeated description can be omitted.

When the laundry inside the drum is stuck during the water supply step, the laundry may be partially wet. In particular, clothing located in the center of a piece of tangled clothing cannot be wet and only clothing located in a surface area of the piece can be wet. If only a few clothes are wet, washing cannot be implemented in the washing cycle and the washing capacity may be impaired. As a result, the control piece can drive the drum in the filtration movement to wet the laundry evenly if the laundry is stuck.

That is, the control part opens the water supply valve for the water supply and drives the circulation pump to circulate the washing water simultaneously. In addition, the control part rotates the drum at a predetermined RPM. The predetermined RPM is determined to be an RPM that allows the garment not to be dropped by gravity, but to remain in close contact with the inner surface of the drum during drum rotation. As a result, the predetermined RPM can be adjusted for the centrifugal force generated by the rotation of the drum to be greater than the acceleration of gravity when the drum is rotated. In addition, the predetermined RPM can be adjusted to be less than an area of excessive speed (about 200 RPM to 35 RPM) that generates resonance in the washing machine. If the drum is rotated at an RPM greater than the area of excessive speed, noise and vibration can increase considerably by resonance. As a result, the predetermined RPM can be adjusted to be approximately 100 RPM to 170 RPM in this control method.

As a result, once the control part rotates the drum at the predetermined RPM, the laundry may be in close contact with the inner surface of the drum, due to the centrifugal force. The washing water supplied through the circulation line and the water supply line can be distributed along the rotation of the drum. The distributed washing water can be supplied to the drum and the laundry in close contact with the inner surface of the drum, so that the laundry can be evenly wetted.

M.1.2 Wet clothing (S2135):

After the water supply step, the control piece can start a wetting step. In the wetting stage, the control piece turns off the water supply valve. The control part drives the drum and water

89/104 washing is circulated while driving the circulation pump. Although the action of wetting the laundry is implemented in the water supply step, the water supply valve is turned off in the wetting step and the wetting action can be implemented by driving the drum.

In the wetting stage of this course, the control piece activates the drum to implement the wetting action. In this case, the control piece can drive the drum in the rolling motion. As the rolling motion moves the laundry inside the drum together with the rotation of the drum, the washing water comes in contact with the laundry frequently and the action of wetting the laundry can be applied without problems.

When implementing the wetting step, the control part classifies the wetting step in the first and second wetting steps. The first and second stages of wetting the laundry can be conducted according to drum movements, that is, the control piece can control the drum movements of the first stage and the second wetting stage to be different from each other. . The operation of the circulation pump is as follows.

Specifically, in the first step of wetting the laundry, the control part can drive the drum in one of the rolling and / or step movements. The selection of driving movements of the drum can be determined according to the amount of laundry. That is, if the amount of laundry inside the drum is less than a predetermined reference value, for example, if the amount of laundry is small, the control piece can drive the drum according to the stepped movement. If the amount of laundry is the reference value or more, the control piece can drive the drum according to the rolling motion.

As mentioned above, if the amount of clothing is small, the effect of falling clothing from the step movement can be improved. As a result, if the amount of laundry is small in the first step of wetting the laundry, the stepping motion drops the laundry with the maximum fall distance to allow water to be absorbed into the laundry. In the meantime, if the amount of laundry is large in the first step of wetting the laundry, the rolling motion is implemented. This is because the falling distance of the clothing from the step movement is not relatively large in the case of large amounts of clothing.

Thus, in the second step of wetting the laundry, the control piece can

90/104 drive the drum to a pre-determined RPM that allows the laundry to be in close contact with the inner surface of the drum, not dropped by gravity, that is, according to the filtration movement. Eventually, the drum is spun at the predetermined RPM and the clothing may be in close contact with the inner surface of the drum due to the centrifugal force. The washing water supplied by the circulation pump is supplied to the laundry attached to the inner surface of the drum evenly and therefore the laundry can be wetted evenly.

In the second step of wetting the laundry, the control piece can implement another driving movement of the drum after the filtration movement. For example, the control part can implement the rolling movement after the filtration movement. In this case, the filtering movement distributes the laundry to supply the washing water to the laundry and the rolling movement moves the laundry to wet the laundry in the washing water evenly.

M. 1.3 Heating (S2137):

After that, the control part starts a heating step. Specifically, the control part drives the drum according to one of the rotating and / or rolling and / or oscillating movements in the heating step, with the heater provided in the tub to heat the washing water carried out in the tub.

In the washing machine of the second mode, the gap between the drum and the bowl is larger than the gap in the first mode. Because of this, when the wash water is heated by activating the heater, the drum is rotated and only the wash water kept in the tub is heated, not the wash water kept in the drum. As a result, compared to the heated wash water, contaminants from the laundry may not be removed in the washing step, which will be described later, because of the relatively low temperature of the laundry.

Because of this, the control method applied to the washing machine according to the second mode activates the circulation pump in the heating step, to circulate the washing water. The heated wash water kept in the tub is re-supplied to the upper part of the tub by the circulation pump in such a way that the laundry can be heated. However, in the heating step, the circulation pump can be driven intermittently at a predetermined interval, and not driven continuously. In particular, in the heating step, the circulation pump can be controlled so that the

91/104 circulation pump idle time is greater than the on time. If the circulation pump is driven continuously in the heating step or if the circulation pump on time is longer than the idle time, the washing water not heated to the predetermined temperature would be circulated and the washing water cannot be heated to the desired temperature.

If the heater is provided in the tub, it is important to start the heater when it is not exposed to the surface of the water. If the heater is activated when exposed, too much load is applied to the engine and the heater may malfunction. As a result, if the heater is activated in the heating step, a predetermined water level away from the heater (reference water level) can be maintained in the heating step. That is, when the water level is below a reference level in the heating step, the control part turns the heater off. When the water level rises to the predetermined level or more by re-supplying water, the control part turns the heater on again (off).

However, if the heating step uses the washing machine shutdown method according to the second mode, a lot of load can be applied to the heater and a variety of circuits and washing machine usage can be reduced.

In other words, the heating step of the washing machine according to the second mode starts and heats the heater while simultaneously driving the circulation pump, as mentioned above. As a result, the water level inside the tub cannot be maintained regularly by driving the circulation pump, but it can vary to a predetermined degree continuously. In this case, the water level inside the tank is varied enough to be reduced below the reference water level. Especially, if the water level inside the tank varies beyond the reference level, the heater can be activated if the water level is beyond the reference level and switched off if the water level is below the reference value, so that the engine start / stop action can be repeated continuously. The action of turning the heater on / off can put a lot of load on the heater and the variety of circuits, and this can shorten the useful life.

As a result, if the water level inside the tub is lowered to reach the reference level while driving the engine in the washing machine heating step according to the second mode, water replenishment can be implemented to avoid the repeated on / off action of the

92/104 heater. Specifically, when the water level inside the tank is reduced below the reference level in the heating step, the control part interrupts the conduction of the drum and turns off the circulation pump. At this time, in addition, the water supply valve is opened to implement the water re-supply. Specifically, when the water level inside the tank is reduced below the reference level in the heating step, the control part interrupts the conduction of the drum and turns off the circulation pump. At this time, in addition, the water supply valve is opened to implement the water supply. However, water replenishment can be implemented for a predetermined time, or until the water supply is implemented for the water level to reach the reference level, or beyond the reference level by detecting the water level. A specific water level of the water supply can be differentiated according to the type of course selected in the initial heating phase.

M.1.3 Washing (S2139):

After the heating step, the control part can implement a washing step configured to drive the circulation pump while driving the drum. In the washing step, a driving movement of the drum can be properly selected from among the drum movements according to the stroke selected by the user. For example, a driving motion of the drum of the washing step can be determined, similar to one of the washing steps provided in the courses above. The circulation pump can be driven at a predetermined interval to circulate the washing water kept in the tub.

M.2 Rinsing cycle (S2150):

Once the wash cycle is completed after the above steps, the control piece can start a rinse cycle. The general rinse cycle can include a rinse-centrifugation step, a water supply step, a drum drive step and a water drain step. First, the control piece starts rinsing-spinning, rotating the drum at a second rotation speed (RPM 2) (S2151), in the rinsing-centrifugation step, to remove moisture and detergent remnants on the laundry, by turning the drum at approximately 500 RPM to 700 RPM. The control piece stops the drum and opens the water supply valve to supply washing water to the tank. The rinse water level can be programmed according to the course selected by the user, or according to manual adjustment of the

93/104 user.

After the water supply, the control part drives the drum at a first rotation speed (RPM 1) at a predetermined interval. In the drum driving stage, the control piece controls a driving motion of the drum and removes detergent from the laundry. The control part of this step can control the drum to be one of the rotating and / or step and / or friction and / or rolling and / or oscillating motion, described above.

Thus, the control piece interrupts the conduction of the drum and activates the water drain pump to drain the washing water kept in the tub to the outside (S2153).

The centrifugation cycle, the water supply step, the drum driving step and the drainage step described above can make up a single cycle of the rinse cycle. The control part can implement the cycle once or several times, depending on the selected stroke or the user's selection. However, the single cycle of the rinse cycle can include the rinse-centrifugation step. The second rotation speed of the rinse-centrifugation step can correspond to about 500 RPM to 700 RPM, as mentioned above, and the rotation speed of this rinse-centrifuge can correspond to the area of excessive speed (about 200 RPM to 350 RPM), which generates resonance from the washing machine.

As a result, if the laundry located on the drum is not evenly distributed, a laundry distribution step, configured to distribute the laundry, can be implemented and, after that, the drum speed can be accelerated for rinsing-centrifuging. The laundry distribution step repeatedly rotates the drum at the predetermined RPM clockwise and / or counterclockwise. After the laundry distribution step, an eccentricity level of the drum is identified. If the eccentricity level of the drum is below a predetermined value, rinsing-centrifugation can be implemented. If the level of eccentricity is the predetermined value or more, the laundry distribution step can be repeated. As the laundry distribution step is implemented before the rinse-centrifugation step, the rinse cycle time can be increased. In particular, as the laundry distribution step is repeated, the rinse cycle time can be visibly increased and the time consumed by the rinse cycle cannot be predicted accurately.

As a result, to solve the problem above, a rinse cycle control method capable of reducing the total time consumed by the rinse cycle.

94/104 rinse will be described.

As shown in Fig. 21, the washing machine rinsing cycle according to the second mode can include a water supply step, a drum driving step (S2151) and a water drain plug (S2153). In comparison with the first mode, the rinse cycle according to the second mode omits a rinse-centrifugation step. As the rinse cycle of the spin cycle is omitted, the rinse cycle time can be reduced as much as the rinse cycle time and the laundry distribution step may not be necessary, thus significantly avoiding the increase in the rinse cycle caused by repetition of the clothes distribution step. Although omitting the rinsing step will reduce the rinsing cycle time, the rinsing step set to remove detergent remnants by rotating the laundry at a relatively high speed is omitted, so it would be difficult to remove detergent remnants sufficiently.

As a result, in the rinse cycle control method according to the second mode, the drum is rotated at a second rotation speed (RPM 2) for about 1 to 3 minutes, and is not interrupted in the water drainage step. . The second speed of rotation is determined to be a predetermined speed that allows the laundry to be attached to the inner surface of the drum due to gravity, and does not fall off, during the rotation of the drum. The second speed of rotation can be set for the centrifugal force generated by the rotation of the drum to be greater than the acceleration of gravity. In addition, the second rotation speed can be set to be less than the excess speed area of the washing machine. If the drum is rotated over the area of excessive speed, the resonance can increase noise and vibration noticeably. As a result, the second speed of rotation can be configured to be approximately 100 to 170 RPM.

Eventually, the drainage step rotates the drum at a predetermined speed and therefore the laundry may be in close contact with the inner surface of the drum due to the centrifugal force, in order to remove detergent remnants from the laundry. Compensating for the rinse-centrifugation step, the drainage step rotates the drum at the second speed of rotation to prevent deterioration of the rinsing capacity.

In the step of rotating the drum with the second speed of rotation (the predetermined speed that allows the laundry to be in close contact

95/104 with the inner surface of the drum), if the water retained in the tub is drained, all drainage steps can be implemented before the rinse cycle. That is, even if the water is drained in the wash cycle, the step of turning the drum at the predetermined RPM can be implemented.

M. 3 Spin cycle (S2170);

A spin cycle for this stroke can be similar to the spin cycles of other strokes, for example, the spin cycle for Stroke A. Thus, the more detailed description of it will be omitted.

Course M described above can be applied to the washing machine according to the second mode. However, Course M can also be applied to the washing machine according to the first modality. That is, Course M can be applied to any washing machine according to the first and second modes.

N. TIME MANAGEMENT OPTION:

A time management option will now be described. Generally, when a specific course is selected, an operation of the selected course begins based on a predefined algorithm and the operation ends in a predetermined amount of time. The operating time required to implement the course can be for the total time required by the individual cycles that make up the course. This total run time can be displayed on display part 119.

Under certain circumstances, the operating time can be very long. For example, if the user has to leave in 1 hour and the scheduled operating time is 1 hour and 20 minutes, the operating time is 20 minutes longer than the user desires. In contrast, severe contamination can make the washing operation implemented for 1 hour and 20 minutes not sufficient to wash the laundry. To solve the problem, a washing machine and control method capable of managing time are provided.

The washing machines described above may include a time management option provided to manage time. That is, the operating time for a specific stroke can be increased or decreased through the option part. Specifically, the user can select a time-saving option from the time management option. Alternatively, the user can select an intensive option through the option of managing time. If none of these options are selected, the operation can be implemented according to the predefined course. This time, the selection of

96/104 manage can be implemented before the wash cycle begins and after selecting the operating course.

For example, when the user selects the option to save time, if the running time of the cotton course is 120 minutes, the required operating time can be reduced to, for example, 100 minutes. When the user selects the intensive option, the operating time can be increased to 140 minutes, to ensure sufficient cleaning of heavily contaminated clothing. There may be a predetermined difference between the predefined time and the time actually needed.

The time required for the wash cycle and / or the rinse cycle can be changed according to the selection of the time saving option. That is, the cycle whose required operating time is changed / adjusted may be different, depending on the selected stroke. For example, in the case of the cotton course, the synthetic course and the mixing course, it is important to improve the washing capacity. Because of this, the time required for the normal wash cycle cannot be changeable, even if the time saving option is selected. Thus, the time required for one of the components of the rinse cycle can be considered for adjustment.

The rinse cycle repeats the water supply, water drainage and centrifugation. The rinse can be implemented twice, three times, or four times. Centrifugation can be implemented in the same order as the centrifugation cycle, with the RPM and main spin time less than that of the centrifugation cycle. As a result, when the time-saving option is selected, the main turn of the rinse cycle can be omitted.

When the option to save time is selected, the step determining the amount of clothing can be omitted, depending on the selected course. For example, when the course for wool, delicate clothing or sport is selected, the quantity of this special fabric is relatively small. If these pieces of fabric become contaminated, the user tends to wash them immediately. As a result, it is rare to wash a large amount of these types of clothing in a single stroke operation. Considering that the determinant step of the amount of clothes can be omitted when the course for wool, delicate clothes or sport is selected.

In contrast, when the intensive option is selected, the number of rinse implementations in the rinse cycle or the required wash cycle time can be increased, or both can be increased.

97/104

This time management option satisfies the purpose of the specific course and allows the user to manage time conveniently.

IV. DRIVE DRIVE MOTION ACCORDING TO THE COURSE AND COURSE STEP

A driving movement of the drum according to each cycle of each stroke will now be described. As mentioned above, the driving motion of the drum includes a combination of the direction of rotation of the drum and the speed of rotation of the drum, and differentiates the direction of fall and the point of fall of the laundry located on the drum to compose the different movements of the drum. These driving movements of the drum can be implemented under engine control.

As the laundry is lifted by the elevator provided on the inner circumferential surface of the drum during drum rotation, the rotation speed and direction of rotation of the drum are controlled to differentiate the shock applied to the laundry. That is, the mechanical force, including the friction between the garments, the friction between the clothes and the washing water and the shock of falling can be differentiated. In other words, a beat or friction level of the laundry can be differentiated to wash the laundry, and a laundry distribution level or a laundry turnover level can be differentiated.

As a result, a driving motion of the drum can be differentiated according to each cycle that makes up several washing strokes and each specific step that makes up each cycle, so that the laundry can be treated by an optimized mechanical force. Because of this, the washing efficiency can be improved. In addition, driving motion of the single fixed drum can result in excessive washing time. A driving motion of the drum for each cycle will now be described.

Wash cycle:

A washing cycle includes a step determining the amount of clothes, the water supply step and a washing step. The water supply step includes a detergent dissolving step configured to dissolve detergent and a wetting step. The detergent dissolving step and the laundry wetting step can be provided independently, separate from the water supply step. The heating step can also be provided according to each stroke.

1.1. Determination of the Quantity of Clothes:

The electrical currents used to spin the drum are measured to

98/104 implement the step determining the amount of clothing. In this case, when the drum is rotated in a predetermined direction, the consumed currents are measured and the drum can be driven according to a single rotation movement, for example, the rotating movement, in the stage determining the amount of laundry.

1.2 Water supply:

In the water supply step, the washing water is supplied together with detergent and a detergent dissolution step can be implemented. To improve the efficiency of the wash cycle, the detergent dissolution can be completed effectively in an initial step of the water supply step. To dissolve the detergent in the wash water quickly, a movement configured to apply mechanical force can be effective. That is, a great mechanical force is applied to the washing water to dissolve the detergent in the washing water more effectively. As a result, in the detergent dissolution step the drum is rotated according to the step movement and / or the friction movement. As mentioned above, step motion and friction motion rotate the drum at a relatively high speed, applying a sudden brake to the drum to change direction, and great mechanical force can be provided. A combination of step motion and friction motion may be possible at this step.

At the wetting stage it is important to soak the laundry in the washing water mixed with the detergent. In this case, a driving movement of the drum may be the filtration movement. Alternatively, the filtering movement and the rolling movement can be implemented sequentially. The rolling motion continuously turns the laundry so that the washing water kept at the bottom of the drum comes into contact with the laundry evenly and is suitable for wetting the laundry. The filtration movement expands the laundry during the rotation of the drum to bring the laundry in contact with the inner circumferential surface of the drum while spraying the washing water in the drum simultaneously, such that the washing water can be discharged from the tub through the clothes and drum holes due to centrifugal force. As a result, the filtration movement expands the surface area of the laundry and allows washing water to pass through the laundry. Therefore, an effect of providing washing water to the clothes evenly can be achieved. In addition, to use this effect, two different driving movements of the drum, that is, the filtration movement and the

99/104 rolling motion, are repeated sequentially in the wetting step. If the amount of laundry is a predetermined value or greater, the effect of wetting the laundry can be impaired in the rolling motion with a relatively low speed of rotation of the drum and thus the rotating motion with a relatively high speed of rotation of the drum can be implemented instead of the rolling motion.

However, the detergent dissolution step or the laundry wetting step of the water supply step can be classified according to the driving motion of the drum when the washing water is continuously supplied. As a result, it is difficult for the user to distinguish the above steps in the water supply stage. From the user's point of view, it appears that the drum is driven according to one of the rolling and / or rotating and / or frictional movements in the water supply stage, or a combination of two or more of the movements.

Depending on the type of clothing fabric, there may be strokes configured to prevent damage to the clothing fabric. In addition, according to the course, there may be courses configured to suppress noise generation when laundry is washed based on the courses. When the drum is driven according to the movement capable of applying a mechanical force in the water supply stage, damage to the clothing fabric or noise generation can be difficult to avoid, in general. As a result, in the water supply stage, movements capable of reducing noise generation as much as possible or preventing damage to the fabric are provided. In these courses, the detergent dissolving effect and the laundry wetting effect are achieved so that, in these courses, the drum can be driven in the oscillating movement or the time of the rolling movement can be increased.

The oscillating movement can minimize the movement of the laundry inside the drum, compared to other movements, and can minimize the damage to the fabric generated by the friction of the garments and the friction between the laundry and the drum. In addition, the rolling motion induces the movement of the laundry along the inner surface of the drum and does not generate shock caused by the sudden drop of the laundry.

If the dissolution of the detergent and the action of wetting the laundry are implemented in a water supply step, a circulation step configured to circulate the washing water can be provided in at least one predetermined step. This circulation step can be implemented

100/104 through the water supply step, or at a predetermined stage of the water supply step.

1.3 Heating:

In a heating step, a driving motion of the drum configured to transmit the heat generated while the heater supplied in the tub heats the washing water for the laundry can be provided. In the heating step, the drum is driven according to the rotating movement configured to rotate the drum in the predetermined direction continuously. If the direction of rotation of the drum is changed, a swirl is generated in the washing water and the efficiency of heat transmission can be deteriorated. If the amount of laundry is less than a predetermined amount of laundry, the drum is driven in the rolling motion. If the laundry quantity is the predetermined or greater quantity level, the drum is driven in the rotating motion. The rolling movement can warm up the laundry sufficiently if the amount of laundry is less than the predetermined level. If the amount of laundry is the predetermined level or greater, the rotating motion configured to rotate the drum at a relatively high speed may be appropriate.

1.4 Washing:

A wash step can be the longest in the wash cycle. In the washing step, contaminants from the laundry can be substantially removed and a driving motion of the drum from the washing step can be a movement capable of moving the laundry in various patterns. For example, the driving movement of the drum of the washing step can be one of, or a combination of, the movement by step and / or the rotating movement and / or the rolling movement. This combination of movements can apply mechanical force to the clothing. Especially, in the case of a small amount of clothing, a combination of these movements can be effective.

The driving movement of the drum of the washing step can be a combination of the filtering movement and the rotating movement. As a driving motion of the drum can continuously provide washing water for the laundry to improve washing efficiency and can apply mechanical force to the laundry evenly to improve the washing efficiency, this combination can be effective with a large amount of laundry.

A heating step is provided before the washing step and the washing water can be heated in the washing step to improve the

101/104 washing efficiency. If the washing water is heated, driving movements of the drum can be combined. For example, if the heater supplied in the tub is activated to heat the washing water, the drum can be driven according to a driving motion of the drum without any sudden brakes.

As mentioned above, in strokes configured to prevent damage to the fabric and to suppress noise generation, a movement capable of applying relatively weak mechanical force to the laundry can be provided in the washing step. For example, in the washing steps of the courses above, the oscillating movement can be implemented to reduce the generation of noise and prevent damage to the fabric. As a result, the operating time of the oscillating movement may be longer than that of other movements in the course. If the washing step is carried out only by the oscillating movement, the washing efficiency can be deteriorated and a movement having a great mechanical force can be additionally provided. The operating time of the movement having great mechanical force can be configured to be shorter than the movement having little mechanical force.

2. Rinse cycle:

In the rinse cycle, the water supply, drum driving and drainage steps are repeated to rinse contaminants associated with laundry or detergent remnants. As a result, a driving movement of the rinsing cycle drum may be a movement capable of generating an effect similar to that of friction. For example, the motive movement of the drum of the rinsing cycle may be the frictional movement and / or the oscillating movement. Both the frictional movement and the oscillating movement have the effect of rubbing and swinging the laundry in the washing water continuously, to improve the rinsing capacity.

When the drum is driven in the rinse cycle, a circulation step configured to circulate the washing water kept in the tub inside the drum and the filtration movement can be implemented together. That is, the washing water is sprayed into the drum and the laundry is washed by the flowing water. The filtration movement generates a great centrifugal force and can separate the detergent and contaminants from the laundry, together with the washing water.

In the rinse cycle, the washing water can be drained along with the bubbles by using the mechanical force applied to the laundry during drainage and / or intermediate centrifugation. As a result, the drum is driven in step or rotating motion. Dropping the raised clothes, the efficiency

102/104 washing can be improved and the bubbles can be removed without problems. The driving movement of the drum can be differentiated according to the amount of laundry. That is, in the case of a small amount of clothing, the step movement is implemented to generate a maximum fall distance. In the case of a large amount of clothing, the rotating movement is implemented.

As mentioned above, in the courses selected to prevent damage to the fabric or to suppress noise generation, the movement capable of applying a relatively weak mechanical force to the laundry can be provided in the rinse cycle. For example, oscillating motion can be provided in the rinsing cycles of strokes. In the course selected to reduce the washing time, it is possible to reduce the rinse cycle time. For example, the filtration movement consumes a relatively large amount of time and, thus, the filtration movement can be omitted in the drum driving step of the rinse cycle in the case of a selected stroke to reduce the overall washing time.

3. Spin cycle:

In a spin cycle the drum is rotated at a predetermined speed or higher to remove moisture contained in the laundry and the spin cycle can include a laundry step to untangle the laundry and an eccentricity measurement step to accelerate the rotation speed drum at a predetermined RPM. A suitable driving movement of the drum can be selected according to the object of each stage. For example, it is advantageous at the stage of untangling the clothing, applying relatively large mechanical force to the clothing. If a movement capable of applying a large mechanical force is provided in the previous rinse cycle, even a movement having a weak mechanical force is sufficient. In addition, to accurately measure the eccentricity, a driving motion of the drum configured to rotate the drum in a single direction continuously may be appropriate in the eccentricity measurement step.

V. NEW COURSES

In describing the various strokes, each stroke includes a wash cycle, a rinse cycle and a spin cycle. However, it is possible to omit a single cycle from each course according to the user's selection. That is, it is possible to omit the washing cycle of Course A (Normal Course) or to omit the rinsing cycle of Course B (Course for Heavy Contaminants) or to omit the cycle of washing

103/104 centrifugation of Course C (Rapid Boiling Course). By extension, one of the cycles provided in each course can be defined as an auxiliary course. For example, the washing cycle of Course F (Course for Functional Clothing) can be defined as a new single course. In this case, it can be referred to as washing functional clothing. Instead of the wash cycle, the rinse cycle or the spin cycle provided in each stroke can be defined as a new stroke.

Despite the wash cycle, the rinse cycle and the spin cycle are described in a specific order to explain each of the courses, such cycles of one course can be combined with cycles of another course to establish the new course. For example, the rinse cycle and the centrifuge cycle of Course A (Normal Course) can be combined with the washing cycle of Course B (Course for Heavy Contaminants) and defined as a new course. Alternatively, each cycle can be taken from the other courses. For example, the rinse cycle of Course A (Normal Course) and the spin cycle of Course M can be combined with the wash cycle of Course B (Course for Heavy Contaminants) and defined as a new course. In this case, steps configured to connect the cycles can be adjusted or changed as appropriate.

In addition, the new course can be taken based on the efforts and conditions of the suit. Figures 22 to 25 illustrate the steps, effects and conditions used to determine movements for the normal course, strong movement course (course for heavy contaminants, rapid boiling stroke and cold wash stroke) and weak movement stroke (color, delicate, or course for wool). Based on the desired effects and conditions, drum movements can be selected interchangeably between normal stroke, strong stroke and weak stroke to create new programs. The disclosure and the present resources can also be applied to the movement of the drum of a dryer, which, for example, are disclosed in Patent Publications No. US 2009/0126222, 2010/0005680 and 2010/0162586, whose entire disclosure is incorporated herein by reference.
