The present invention relates to a semi-drying method of a washing machine, and more particularly, to a semi-drying method of a washing machine for dehydrating laundry by step centrifugal force and simultaneously releasing the tangling of the laundry to dry the laundry to 55 to 70%.

In general, a washing machine includes a cabinet 2 forming an exterior as illustrated in FIG. 1, an outer tub 4 installed as hanging on an inside of the cabinet 2, and the wash water is fresh, and the outer tub 4. It is rotatably installed inside to wash the laundry and laundry contained in the inner tank (6), and the pulsator is rotatably installed on the bottom surface of the inner tank (6) to form a rotating water flow inside the inner tank (6) And a motor 10 installed below the outer tub 4 to be connected to the inner tub 6 and the pulsator 8 to rotate the inner tub 6 or the pulsator 8. It is composed.

Of course, the water supply valve assembly 12 and the detergent box assembly 14 including a water supply valve (not shown) for supplying the washing water together with the detergent to the outer tank 4 and the inner tank 6 on the cabinet 2. Is installed, the lower one side of the outer tank 4 is installed so that the drain valve assembly 16 including a drain valve (not shown) for draining the outer tank 4 and the wash water of the inner tank.

Looking at the washing method of the washing machine according to the prior art configured as described above are as follows.

First, when the laundry is loaded on the inner tank 6 and the washing machine starts to be driven after the washing pattern is set, the inner tank 6 is stirred and rotated at a low speed by a motor 10 to detect the quantity of the laundry. The water supply level and the detergent amount are set according to the quantity of water.

Thereafter, washing and rinsing, and a dehydration stroke are performed according to the set washing pattern, thereby washing the laundry.

That is, after washing water is supplied to the inner tank 6 together with a detergent during washing administration, the inner tank 6 and the pulsator 8 are rotated at a medium speed by the motor 10, and the laundry is washed in the inner tank 6. Washed by friction and rotational water flow, and only wash water is supplied to the inner tank 6 during the rinsing stroke, and the laundry is rinsed while the inner tank 6 and the pulsator 8 are rotated at a medium speed.

In addition, while the inner tank 6 is rotated at a high speed at 1000 to 3000 rpm for 3 to 5 minutes during the dehydration stroke, the laundry is dehydrated by centrifugal force.

However, in the washing machine according to the prior art, since the inner tank 6 is rotated at a high speed so that the laundry is dehydrated by centrifugal force during the dehydration operation, the laundry is entangled with each other after the dehydration and the laundry is entangled with each other. As it is stuck, the process of taking out the laundry and untangling the laundry is not only difficult to hang on the drying rack, but also to dry the laundry for a long time outside, which is subject to weather and time constraints. There is a necessary problem.

The present invention has been made to solve the above problems of the prior art, it is an object of the present invention to provide a semi-drying method of a washing machine to minimize the wrinkles of laundry after dehydration and to increase the dryness of the laundry.

Semi-drying method of the washing machine according to the present invention for solving the above problems is the first step after the laundry is loaded in the washing tank, the washing tank is stirred as the power of the motor is turned on / off; In the first step, if the amount is less than the set value, the washing tank is stirred while the tangling of the laundry is released, and after the stirring process, the laundry tank is rotated at a lower speed than the set dehydration speed and the simple dehydration process in which the laundry is first dewatered; And a second step of performing a main dehydration process in which the laundry is secondly dehydrated while the washing tank is rotated at the dehydration speed after the simple dehydration process. The second step includes a third step in which the cycle is performed a plurality of times.

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

The semi-drying method of the washing machine according to the present invention increases the speed of the washing tank step by step while releasing the tangling of the laundry by stirring the washing tank in the middle, thereby minimizing the wrinkles of the washing and drying the laundry during general dehydration. Increase the dryness to 50% or more, that is, 55 to 70%.

That is, in the first step (S10), after the laundry is deposited in the washing tank, as the power of the motor is turned on / off, the washing tank is agitated and the quantity of water is sensed.

At this time, when the laundry is a wet cloth, a large load is placed on the motor due to the high moisture content of the laundry, and the vibration of the washing tank is likely to be excessive, so that the duty value is the ratio of the on / off time (t1 / t2) of the motor. It is preferable to stir the said washing tank shortly by making do small.

On the other hand, if the amount is too large, the laundry is severely tangled and the washing tank is rotated at high speed, so the vibration of the washing machine is large, it is necessary to limit the amount to 20% to 40% of the washing capacity.

Therefore, the first step S10 includes a step S12 of generating an alarm sound to warn the user of the excess amount without proceeding to the next step if the detected amount exceeds the set value.

In the second step (S20), if the quantity is less than the set value in the first step (S10), as the power of the motor is turned on / off, the washing tank is stirred while the tangling of the laundry is released (S22) and the stirring process (S22) After the washing tank is rotated at a lower speed (V1) than the set dehydration speed (Vo), the simple dehydration process (S24) that the laundry is first dehydrated, and the dehydration process (S24) after the simple dehydration process (S24) Rotation is made to Vo) is the dehydration process (S26) that the laundry is dewatered secondary.

Here, in the stirring process (S22), the laundry may be deposited on one side or attached to the wall surface of the washing tank so that the laundry is evenly deposited by dropping the washing tank and falling off from the wall surface of the washing tank.

At this time, since the laundry is accumulated evenly to some extent in the first step (S10), the duty value d1 of the motor so that the laundry is evenly deposited and dehydrated by centrifugal force in the stirring process (S22). It is preferable to increase the power-on time to be greater than the duty value do of the motor in the first step (S10).

In the simple dehydration process (S26), the heavier the laundry, the greater the centrifugal force acting on the laundry, and thus the laundry is compressed on the wall of the washing tank. Thus, when the washing tank is rotated, the laundry is dehydrated while being pushed to the wall surface of the washing tank by the centrifugal force. The rotation speed (V1) of the washing tank is set to medium speed, that is, 600 ~ 900rpm so that the laundry is not caught in the hand of the washing tank.

 The dehydration process (S26) is because the laundry is dewatered in the primary dehydration process (S24) is relatively light, so even if the dehydration rate (Vo) is higher than the simple dehydration process (S24), that is, 800 ~ 1200rpm laundry centrifugal force It is attached to the wall of the washing tank by the dehydration, but is not caught in the hand of the washing tank, the laundry can be dried to a slightly less dry state with almost no wrinkles.

In the third step (S30, S40), the stirring step (S22), the simple dehydration step (S24), and the present dehydration step (S26) of the second step (S20) forms one cycle, which cycle is 3 to 5 By carrying out a plurality of times, the laundry is dehydrated in stages so that the dryness of the laundry is about 55% to 70%.

At this time, the moisture content of the laundry is much reduced compared to the stirring step (S22) of the second step, the duty values d2, d3 of the motor in the third step (S30, S40) is the stirring step (S22) of the second step Is set larger by increasing the power-on time t1 of the motor.

In addition, since the water content of the laundry gradually decreases as the cycle is performed a plurality of times in the third step (S30, S40), the duty values d2, d3 of the motor are also gradually increased.

In addition, since the water content of the laundry gradually decreases as the cycle is performed a plurality of times during the simple dehydration process (S34, S44) in the third step (S30, S40), the rotational speed (V2, V3) of the washing tank is also gradually increased. It is desirable to.

Semi-drying method of the washing machine according to the present invention constituted as described above is carried out a plurality of cycles of agitation process loosening the laundry, simple dewatering process of the first dewatering of the laundry, and this dewatering process of the second dehydration of the laundry As the laundry is dewatered step by step, it is possible to improve the dryness of the laundry, there is an advantage that can minimize the wrinkle of the laundry.

In addition, the present invention, when the washing tank is stirred, by increasing the duty value of the motor as the step proceeds, the laundry is entangled and the dehydration is also progressed by centrifugal force to further improve the dryness of the laundry have.
