Description

Semi-drying method of washing machine {Method of semi-dry for washer}

The present invention relates to a drying method of a washing machine, and in particular, to dry laundry, dehydration of the laundry by centrifugal force through a high-speed rotation of the washing tank, not by the hot air of the heater, and by drying by heat by removing a large part of the remaining moisture. It relates to a semi-drying method of the washing machine to compensate for the problem.

In general, a washing machine is a machine that removes stains on clothes due to friction of rotating water generated by mechanical action along with chemical action of detergent dissolved in wash water. Perform.

In recent years, a washing machine for mounting a heater and a blower fan inside a washing machine to blow heat generated by the heater after washing a dehydration stroke into a laundry to evaporate the remaining water in the laundry to be dried quickly is widely used.

1 is a schematic view showing the configuration of a general dry combined drum washing machine.

Drying drum washing machine as shown in Figure 1, the tub 6 for storing the wash water that is supported by the damper (2) and the hook member (4) in the main body 1 and the water supplied during washing and rinsing, and The tub 6 is rotatably installed and includes a washing tank 8 for washing, rinsing and dehydrating laundry.

In addition, a blower duct 10 communicating with the washing tub 8 is provided at an outside position of the tub 6, and a blower fan 12 for forced circulation of air on the path of the blower duct 10 and the blower air. The front surface of the fan 12 is provided with a drying heater 14 for heating the air supplied to the washing tank (8).

When the laundry is put into the washing tank 8, the washing water is then supplied and the washing tank 8 rotates to perform the washing stroke.

After that, the rinsing process is completed until the dehydration stroke.

When the dehydration operation is completed as described above, the laundry tub 8 is rotated at low speed, and the laundry is mixed evenly. In this state, the drying heater 14 is driven to generate heat at a high temperature and simultaneously drive the blower fan 12. By supplying the high temperature air by the heat generated by the drying heater 14 into the washing tank (8).

The hot air dries the laundry, becomes hot and humid air, flows into the blowing duct 10, and condenses by supplying cold water while circulating inside the blowing duct 10.

At this time, the generated condensate is drained through an appropriate duct and the dry air is repeatedly circulated to dry the laundry by repeating the above process.

However, in the case of a combined-use drum washing machine using the hot air of the drying heater 14, there is a problem in that the device is complicated because a separate device for generating hot air or blowing and circulating it must be provided.

In addition, the power consumption is increased in the process of operating the drying heater 14, when washing the clothing that is weak to heat may damage the cloth.

The present invention has been made to solve the above-mentioned problems of the prior art, and provides a semi-drying method of a washing machine having a separate device in the washing machine or allowing a drying of a predetermined level or more without carrying a large amount of power loss. Its purpose is to.

In the semi-drying method of the washing machine according to the present invention for solving the above problems, the washing tank is rotated at a high speed to dehydrate the laundry, and after the dehydration of the first step, the washing tank is stirred at predetermined time intervals to wash the laundry. The second step of being inflated, and after the laundry is inflated in the second step, the washing tank is rotated to remove the water of the laundry, characterized in that consisting of a third step.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a block diagram showing a general automatic washing machine, Figure 3 is a flow chart illustrating a semi-drying method of the washing machine according to the present invention.

As shown in FIG. 2, the general automatic washing machine is rotatable to allow washing and dehydration of laundry in the tub 26 and the tub 26 to store washing water necessary for washing inside the main body 22. A washing tank 28 is installed, and a pulsator 30 is formed on the bottom surface of the washing tank 28 to form a rotating water flow in the washing water and transmit mechanical agitation force to the laundry. A motor 34 is connected to the washing tub 28 and the pulsator 30 to rotate the washing tub 28 or the pulsator 30.

In addition, a water supply valve 40 is installed above the main body 22 to supply washing water or rinsing water to the tub 26 and the washing tank 28, and the tub 26 is disposed at one lower side of the tub 26. ) And a drain valve 50 for draining the washing water or the rinsing water of the washing tank 28.

An embodiment of a semi-drying method of a washing machine according to the present invention will be described with reference to FIGS. 2 and 3.

First, when the washing and rinsing process of the laundry is completed, the drain valve 50 is opened to drain the washing water in the washing tank 28, and when the washing water is completely drained in the washing tank 28, As the motor 34 repeatedly turns on / off, intermittent dehydration proceeds by rotating the washing tank 28 intermittently to dehydrate the laundry. (See S1, S2, and S3.)

At this time, since the laundry in the washing tank 28 includes a large amount of washing water, the rotation speed of the motor 34 has a relatively low rotation speed, such as 600 rpm, so that the laundry is washed by the centrifugal force of the washing tank 28. While not being caught in the washing water discharge hole (not shown) formed at 28, a certain amount of washing water included in the laundry is dehydrated.

Of course, during the intermittent dehydration in the washing tank 28, the drain valve 50 is in an open state to discharge the wash water contained in the laundry.

On the other hand, when the motor 34 is intermittently rotated, the rotation speed of the washing tub 28 is increased and decreased speed is gradually increased according to whether the motor 34 is driven.

In the second step, after the intermittent dehydration of the first step proceeds for a predetermined time, the motor 34 is always turned on and driven so that the washing tank 28 is rotated at a high speed at a constant speed of 700 rpm or more to dehydrate the residual water contained in the laundry. This dehydration proceeds (see S4).

In the third step, since the laundry may be eccentric to one side in the washing tank 28 while the washing tank 28 is rotated at a high speed, the washing tank 28 is repeatedly stirred at predetermined time intervals. The eccentricity of the washing tub 28 is corrected while inflating the laundry. (See S5.)

At this time, the washing tank 28 is provided with an eccentric detection unit (not shown), by detecting the eccentricity of the washing tank 28 while the washing tank 28 is stirred, to continuously determine whether the eccentricity is below the set value. It is judged as (see S6).

That is, since the eccentricity gradually decreases in the process of inflating the eccentric laundry while the washing tank 28 rotates at a high speed in the second step, it is determined whether to proceed with the next step.

In the fourth step, when it is determined in the third step that the eccentricity of the washing tank 28 is less than or equal to the set value, the control unit determines that the lapping of the laundry in the washing tank 28 is more than a predetermined level. The stirring is stopped, and again, the washing tank 28 is intermittently rotated to remove the residual water of the laundry which has not been dehydrated in the second dehydration of the second step.

Here, removing the residual water of the laundry is a kind of preliminary step for drying the laundry to a predetermined level or more in the fifth step to be described later in order to obtain a higher degree of dehydration in the second dehydration step of the second step.

On the other hand, when the eccentricity sensed in the third step is determined to be greater than the set value, it is determined that the foaming of the laundry in the washing tank 28 is not sufficient, and the washing tank 28 is stirred and at the same time the washing tank ( 28, the third step of detecting the eccentricity is continued (see S5 and S6).

The fifth step is to rotate the washing tank 28 at a high speed of 700rpm or more to dry the already dehydrated laundry to a predetermined value or more (see S8, S9).

At this time, since the laundry is already dehydrated, even if the washing tank 28 is rotated at a high speed, since the weight is not large, the laundry is less likely to receive centrifugal force so that the laundry is not caught in the washing water discharge hole formed in the washing tank 28. Therefore, the washing tank 28 can be rotated at a higher rotational speed in the present dehydration step, and thus the laundry can be dried to a certain level.

On the other hand, the step of rotating the washing tub 28 in the fifth step at high speed can be repeated several times by increasing the rotation speed of the washing tub 28 according to the user's selection.

Accordingly, in the above embodiment, after the washing tank 28 is rotated at 700 rpm or more, the drying rate of the laundry can be further increased by rotating the washing tank 28 again at 800 rpm or more.

In the semi-drying method of the washing machine according to the present invention configured as described above, when the laundry is dehydrated, the washing tank is rotated at a high speed without a separate heater driving to dry the laundry after the laundry is dewatered, and the washing water contained in the laundry is fixed. By drying as described above, it is possible to reduce the use of electric power according to the driving of the heater, and there is no fear of damage to the cloth due to drying by heat, and since the laundry contains predetermined moisture even after drying, the cloth does not wrinkle.
