The present invention relates to a washing machine, and more particularly, to a washing machine scattering prevention structure of the washing machine that can prevent the washing water is scattered by the washing cloth during permeation washing and / or water supply to increase the reliability of the washing machine operation.

In general, a washing machine is a product that removes various contaminants attached to clothes, bedding, etc. by using the action of the emulsification of the detergent or the friction action of the water flow due to the rotation of the wash water or the impact of the pulsator applied to the laundry cloth. And, the washing method is performed by the washing machine, the process of detecting the amount and type of laundry cloth by the sensor to automatically set the washing method, the process of watering the washing water to the appropriate level according to the amount and type of laundry cloth, Washing, rinsing, and dehydration processes are performed by control.

The present invention is of major interest in a washing machine of the permeable washing method that performs permeation washing by spraying the pumped water stream into the rotating tank while rotating the rotating tank and / or pulsator at a high speed during washing.

The washing machine is a permeation washing machine to which the conventional permeation washing method is applied, the pulsator and the rotating tub are integrally formed, and the rotating tub and the pulsator are rotated at a high speed by a predetermined driving means. In addition, the wash water in the rotary tub penetrates the laundry cloth by the centrifugal force generated by the high speed rotation of the rotary tub, and the contaminants attached to the laundry cloth are separated from the laundry cloth. Subsequently, the wash water that has passed through the wash cloth moves to the tub through the through hole formed in the rotating tub, and the wash water introduced into the tub rises along the wall surface of the tub by centrifugal force. In addition, the washing water in which the traveling direction is bent in the upper portion of the tub is dropped into the rotating tub and re-introduced, and the washing is performed by tapping the washing cloth during the falling of the washing water.

In the case of such a washing machine, the washing water penetrates the washing cloth by centrifugal force, and the washing water is dropped from the upper end and taps the washing cloth. Therefore, the washing effect is improved compared to other conventional washing methods. good.

However, in the case of the permeable washing machine, the washing water to be re-introduced into the rotary bath during the permeation washing hits the floating laundry cloth and cannot be re-introduced into the rotary bath. This situation occurs mainly when the laundry cloth is made to protrude upward from the tub cover.

In detail, the case where the laundry cloth protrudes above the tub cover occurs when a large amount of laundry cloth is put into the rotary tub. That is, when a large-capacity duvet and a pillow and the like are put into the rotary tub, the corners of the blanket and the pillow may protrude to the upper side of the tub cover. In particular, in the case of the pillow for the bed has a strong characteristic that the pillow is floating in the water by the air contained in the pillow, washing water injected into the rotating tub by riding the tub during permeation washing is scattered to the outside by hitting the pillow. This phenomenon can lead to water splash.

When the leaked wash water falls between the tub and the case and falls on the bottom surface of the inside of the washing machine, the wash water contacts the electrical equipment provided at the lower portion of the tub, and may cause a problem such as a short in the electrical equipment, resulting in a fire or a safety accident.

In addition, in a country where a carpet culture is developed in which a washing machine is installed on a floor on which a carpet is placed, the carpet may be discarded by the leaked water. Due to the leakage of the wash water, a shortage of wash water occurs, and of course, the washing is not performed smoothly.                         

On the other hand, even when the laundry is not permeable, when the laundry cloth is placed below the water supply port, water supplied through the water supply port may collide with the laundry cloth and flow out between the tub and the case. The wash water spilled as described above causes various problems due to leakage as described above.

The present invention is proposed to solve the above problems, and an object of the present invention is to propose a water scattering prevention structure of a washing machine that can effectively prevent the wash water from scattering during water supply and permeation washing. In addition, an object of the present invention is to propose a water scattering prevention structure of the washing machine, which can improve the safety problem of the washing machine which may be generated due to outflow of the washing water.

In addition, by detecting a washing cloth that can cause water scattering by a predetermined sensing device, by allowing the washing machine to be controlled separately by the detected washing cloth, to prevent the scattering of the washing machine to more reliably prevent the washing water splashing The purpose is to propose a structure.

Water scattering prevention structure of the washing machine according to the present invention for achieving the above object is a case; A tub formed inside the case to accommodate washing water; A rotating tank for forming forced water flow by rotation; A tub cover formed at an upper end of the tub to guide water flow to the tub side; And it is installed on the bottom of the case includes a sensor for detecting the outflow of the wash water.                     

Water splashing prevention structure of the washing machine according to the present invention comprises the steps of washing water flowing between the tub and the case during operation of the washing machine; Washing water is collected on the lower side and sensed by the first electrode sensor; And when the electrode sensor is energized, the rotating tub rotates at a low speed or stops under the control of the controller.

Hereinafter, with reference to the drawings will be described a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily suggest other embodiments within the scope of the same idea.

1 is a cross-sectional view of a washing machine to which the idea of the present invention is applied.

Referring to FIG. 1, the transmission washing machine includes a case 1 forming an external appearance, a tub 2 disposed inside the case 1 to accommodate washing water, and a rotatable inside the tub 2. A plurality of rotating tub 3, the body of the rotating tub 3 is formed integrally with the through-hole 10 and the central part of the rotating tub 3 to allow the wash water to flow to the tub (2) A pulsator 4 rotated together with the rotary tub 3, a tub cover 5 fastened to the upper portion of the tub 5, a water supply valve 9 and a water supply port 8 so that the washing water is properly supplied. And a drain valve 7 and a drain port 6 for draining the wash water. In addition, one side of the inner circumference of the tub cover 5 includes a net 11 for preventing the laundry cloth from rising above the height of the tub cover 5. In addition, in the case where the wash water overflows to the outside of the tub 2 and leaks to the outside, the depression 14 formed by the bottom surface of the case 1 is embedded in order to collect the leaked wash water. The upright support bar 13 and the sensor 16 attached to the support bar 13 are included.

In detail, the tub 2 has an open cylindrical shape and serves to receive the wash water in the case 1. In addition, the rotating tub 3 is installed inside the tub 2 to be selectively rotated in the forward and reverse direction, the wash water accommodated in the rotating tub 3 through the tub 10 through the tub (10). You can exit to side (2). The through hole 10 may be dehydrated by the moisture that is wet to the laundry cloth during dewatering, and the wash water is circulated to the tub (2) through the rotating tub (3) during permeation washing.

In detail, the pulsator 4 is integrally installed at the lower portion of the rotary tub 3 to rotate together with the rotary tub 3. In addition, the tub cover 5 is fastened to the upper portion of the tub 2 and performs a function of guiding the water permeated during permeation back to the rotating tub 3, and extending into the tub cover 5. The net 11 is performed to suppress the rise of the laundry cloth.

In addition, the net 11 is not only serves to suppress the rise of the laundry cloth, is formed on the lower side of the water supply port 8, to suppress the water flowing from the water supply port 8 directly hit the laundry cloth. do. In other words, at least the laundry cloth cannot rise above the position where the net 11 is formed, so even when water flows into the water supply port 8 formed directly above the net 11, the wash water is immediately Since it does not collide with the laundry cloth, it will not leak beyond the tub cover.

In addition, when washing water comes into contact with the wash cloth and water splashes, and flows out between the tub 2 and the case 1, the washing water is sensed by a sensor 16 formed below the case 1. Transfer to the control unit of the washing machine. Then, the control unit of the washing machine to stop the leakage of the wash water by the process of controlling or stopping the drive unit of the washing machine.

In the washing machine according to the present invention, the washing water flow during permeation washing will be described in detail.

The pulsator 4 and the rotating tank 3 are integrally formed, and the rotating tank 3 and the pulsator 4 are rotated at high speed by the motor 13. In addition, the wash water in the rotary tub 3 separates the contaminants attached to the laundry pad from the laundry cloth while passing through the laundry cloth by the centrifugal force formed by the high-speed rotation of the rotary tub 3. Then, the wash water passing through the washing cloth is moved to the tub 2 through the through hole 10 formed in the rotary tub (3). In addition, the wash water introduced into the tub 2 rises along the inner surface of the tub 2 by centrifugal force. The water level of the washing water in the rotating tub 3 will be made of a (U) shape as shown by the centrifugal force.

In addition, a tub cover 5 is installed at the upper portion of the tub 2, so that the washed water is no longer raised and collides with the tub cover 5. In order for the wash water to contact the tub cover 5 and smoothly flow into the tub 2, the contact portion of the vertical and horizontal surfaces of the tub cover 5 may be gently curved. As such, the washing water that has collided with the tub cover 5 is re-introduced into the rotating tub 3, and the washing cloth is struck by a strong stream of water, thereby dropping the dirt stuck on the washing cloth.

In a series of processes as described, the washing water accommodated in the rotating tank 3 is the first washing process in which permeation is performed by centrifugal force, and washing is performed while hitting the laundry cloth by the drop of washing water. Washing is performed by a second washing process, which can be performed repeatedly as a series of cycles. In addition, washing may be performed by an operation in which the pulsator 4 and the laundry cloth collide with each other by the rotation operation of the pulsator 4.

On the other hand, even at the time of water supply, the laundry cloth cannot rise above the predetermined height by the net 11 at the straight bottom side of the water supply port 8. Therefore, the wash water supplied through the water inlet 8 may not flow over the tub cover 5 by colliding with the laundry cloth, but may flow into the tub 2 correctly. That is, when the permeation washing stroke is performed, the net 11 not only does not raise the laundry cloth more than a predetermined height, but also performs a function of preventing the washing water from overflowing even when water is supplied with the washing water.

Furthermore, when the laundry cloth is not completely blocked by the net 11, the washing water may flow out between the tub 2 and the case 1. At this time, the outflowing washing water is collected in the depression 14 of the bottom of the case 1, and the collected water is detected by the sensor 16. When the washing water flowing out by the sensor is sensed, by stopping the rotation of the rotating tank or lowering the rotation speed, the water splash of the laundry cloth can be stopped.

Hereinafter, the configuration of the sensor will be described in detail.

FIG. 2 is an enlarged view of a portion A of FIG. 1.

Referring to FIG. 2, the bottom surface of the case 1 is deformed and embedded in the recess 14, the support bar 13 perpendicular to the recess 14, and the support bar 13. A pair of sensors 16 is included.

In detail, the sensor 16 may be a (+) (-) pair of electrode sensors that determine the presence or absence of the wash water by energizing the current. The electrode sensor is a sensor in which a (+) pole and a (-) pole are formed, and when the (+) pole and the (−) pole come into contact with water collected in one space, current flows out and sends out a signal. In addition, the depression 14 may be formed by the case 1 is recessed, it may be formed on the lowest lower side of the bottom of the case 1 so that the wash water spilled into the depression 14 can be collected. . Furthermore, the recess 14 may be formed by being inserted into a predetermined position of the bottom surface of the case 1 as a separate structure rather than integrally with the case 1.

The operation of the sensor 16 described above will be described. Washing water that collides with the laundry cloth and flows out between the tub 2 and the case 1 flows down to the bottom surface of the case 1 by its own weight, and the washed water that flows down is collected in the depression 14. When the wash water collected is collected at a predetermined height, the electrode sensor 16 is energized. Then, the energization of the electrode sensor 16 is transmitted to the control unit of the washing machine, under the control of the control unit by the operation of the washing machine is rotated at a low speed or the rotation is stopped, it is possible to stop the outflow of the wash water.

3 shows another embodiment of the present invention.

Referring to FIG. 3, the present embodiment is the same as the original embodiment, except that two electrode sensors are formed. In detail, as in the prior art, the first electrode sensor 17 which detects the washing water flowing out due to the collision with the laundry cloth, and the upper side of the first electrode sensor 17 are formed to allow the washing water to flow out in large quantities (the number of days A second electrode sensor 18 is included.

Since the operation of the first electrode sensor 17 is as described through the first embodiment, a detailed description thereof will be omitted. In addition, the second electrode sensor 18 not only detects the washing water flowing out due to the collision with the laundry cloth, but also for some other reason, for example, other reasons such as breakage of the tub and tilting of the washing machine. The washing machine may be used to detect a large amount of washing water flowing out so that the operation of the washing machine is stopped quickly.

4 is a flowchart illustrating the operation of the water scattering prevention structure of the washing machine according to the present invention.

Referring to FIG. 4, operation of the washing machine is started (S 11), and since the washing water is not detected by the electrode sensor 17 in a state in which the washing machine is normally operated, the stroke of the washing machine continues. However, when the electrode sensor is energized (S 12), the wash water flows out so that the rotating tank rotates at a low speed (S 13). However, it may be possible to stop the rotation of the rotating tank does not stop at low speed rotation.

Then, when the washing machine is in progress, when it is detected that the current is energized by the second electrode sensor 18 (S 14), the washing machine is suddenly stopped as a large amount of washing water flows out, and the water supply valve is closed to wash. Inflow of water is blocked (S 15). In some cases, the drain valve may be opened so that the washing water contained in the tub 2 may be drained quickly.

According to the present invention, the washing cloth can be prevented from being raised above the height of the tub cover, and the washing water can be effectively suppressed from scattering during water supply and permeation washing. Furthermore, it is possible to improve a problem regarding the safety of the washing machine that may be generated due to the outflow of the washing water.

In addition, the rise of the washing cloth can be suppressed by the physical network, and the washing machine is automatically stopped or operated at a low speed when water scattering is generated by a predetermined sensing device. It can be operated stably.

In addition, when a large amount of water is leaked by quickly stopping the operation of the washing machine, there is an advantage that can prevent in advance the safety problems that may be caused by the leakage of the wash water.
