Abstract

The present invention relates to a method for solving an unbalance generated during dehydration of a washing machine, in which laundry is dehydrated to improve the dewatering performance by eliminating unbalance caused by one-sided washing in the washing tank during dehydration of the washing machine. .

If unbalance is generated during the dehydration of the conventional washing machine, the amount of washing water used for washing is watered, so the consumption is increased by about 20% based on four rinsing cycles. There is a problem.

The present invention is to solve the problem without de-supply in the case of unbalance in the washing tank during the dehydration process, it is possible to reduce the washing water used for washing, and to reduce the power consumption by shortening the washing time .

Description

THE UNBALANCE DISSOLVED SYSTEM TO OCCURED DURING A DRY

The present invention relates to a method for solving an unbalance generated during dehydration of a washing machine, which is capable of eliminating unbalance caused by washing of laundry to one side in a washing tank during dehydration of the washing machine.

A general washing machine configuration will be described with reference to FIG. 1, the outer tub 2 supported by the snubber bar 1A and the damper 2A of the outer case 1, and the high speed rotation at the time of dehydration and the laundry 7 ) Dehydration tank (3), a motor (5) which is a power source located on one side of the lower end of the outer tank (2), a clutch (6) for switching the washing and dehydration, and a lower end of the dehydration tank (3). A pulsator (4) which is located at the center and stirs left / right stirring during washing, an unbalance sensor (8) for detecting the bias of the laundry (7) in the dehydration tank (3), and a water level sensor for detecting the water level of the washing water It is composed of (9), reference numeral 3A is a dehydration tank wall, 10 is a water supply valve.

Referring to the operation during the dehydration of the general washing machine configured as described above, first, the power according to the rotation of the motor 5 rotates the laundry 7 together with the dehydration tank 3 at a high speed through the clutch 6.

The high speed rotation of the dehydration tank (3) causes a phenomenon in which the laundry (7) contained therein occurs, and due to the deflection of the laundry (7), the outer tank (2) located on the outside of the dehydration tank (7) is hit. As a result, the outer tub 2 vibrates.

Due to the severe vibration of the outer tub 2, the vibration is detected by the unbalance sensor 8 located above the outer case 1.

Referring to FIG. 1 and FIG. 2, the unbalance elimination step that occurs during dehydration of a conventional washing machine is described as follows.

If unbalance occurs during dehydration, after dehydration is stopped, the water supply valve 10 is re-watered up to the level set in the dehydration tank 3 in which the laundry 7 is contained, and to the water level set after the first step. After the water supply is completed, the second step of evenly dispersing the laundry 7 by rotating the motor 5 in a mode for evenly dispersing the laundry 7, and evenly dispersing the laundry 7 of the second step The third step and the fourth step of starting the rehydration after the drainage of the third step.

Referring to FIGS. 1 and 2 of the conventional washing machine configured as described above with reference to FIG. 1 and FIG. 2, when the dewatering process dewaters, the unsealing tank 2 is severely hit by the deflection of the laundry 7 in the dewatering tank 3. When the balance phenomenon is detected by the unbalance sensor 8, the dehydration is stopped and then re-watered to the dehydration tank 3 through the water supply valve 10 as shown in FIG.

When rewatering is completed to a certain level in the dehydration tank 2, the water supply is stopped and the motor 5 is rotated in a mode for evenly dispersing the laundry 7.

Rotation of the motor 5 allows the laundry 7 in the dehydration tank 3 to be evenly dispersed, and when the laundry 7 in the dehydration tank 3 is evenly dispersed, drainage begins. Dehydration will begin.

In the conventional washing machine, when unbalance occurs when the laundry in the dehydration tank is biased to one side, the washing machine in the dehydration tank is re-watered, rotates a motor to evenly disperse the laundry, and then starts dehydration after draining.

However, as described above, water consumption due to rewatering during dehydration is increased by about 20%, and there is a problem that power consumption also increases as the washing time becomes longer.

The present invention does not re-water when the unbalance in the washing tank during the dehydration in order to solve the problems described above, by repeatedly rotating and stopping the washing tank and the pulsator containing the laundry to solve the unbalance, washing used during washing It can reduce the number of customers, reduce the washing time and power consumption, so as to solve the complaints of consumers.

Referring to FIG. 3 and FIG. 4 with the same reference numerals as for the same parts as in the prior art when the unbalance occurs in the washing machine.

If the laundry 7 agglomerates to one side in the dehydration tank 3 during the dehydration process, the first step of suddenly stopping by simultaneously rotating the pearlsetter 4 and the dehydration tank 3, and the agglomeration after the first step The laundry 7 is rotated by changing the rotational direction of the dehydration tank 3 and then suddenly stopped, and the first and second steps are repeated a predetermined number of times. A third step of evenly dispersing, and a fourth step of dispersing the laundry 7 entirely by rotating only the pulsator 4 when the laundry 7 is evenly dispersed after the third step, and the washing tank after the fourth step. When the laundry 7 in (3) is distributed evenly, it consists of a 5th step of dehydration.

Referring to Figures 3 and 4 with respect to the step of eliminating the unbalance when the washing machine of the present invention configured as described above is as follows.

First, if an unbalance phenomenon that severely hits the outer tank 2 due to the bias of the laundry 7 during dehydration occurs, the dehydration tank 3 and the pulsator 4 containing the laundry 7 are rotated at the same time after stopping dehydration. And suddenly stop.

As described above, when the laundry 7 is rotated and stopped, the laundry 7 has inertia that is continuously rotated, and the agglomeration between the laundry 7 is weak because the friction according to the position between the laundry 7 is different. The bias is reduced.

At this time, if the laundry 7 is weakened to rotate the dehydration tank (3) by changing the direction of rotation and suddenly stopped, the aggregate of the laundry (7) is weakened, the bias is reduced.

Then, if the dehydration tank 3 containing the laundry 7 is rotated and stopped about 4 times in each direction as described above, the laundry 7 is evenly distributed to one side as shown in FIG. do.

When the laundry 7 is dispersed to one side, only the pulsator 4 is rotated so as to disperse the laundry 7 as shown in FIG. 4 and evenly wash the laundry 7 in the dehydration tank 3. If dehydration is performed after dispersion, unbalance due to the laundry 7 will not occur.

The present invention is to reduce the number of wash water in accordance with the conventional re-supply by eliminating the unbalance of the laundry by repeatedly rotating and stopping while changing the rotation direction of the washing tank in the unbalance of the laundry generated during the dehydration of the washing machine as described above In addition, the power consumption due to the washing time is reduced, so that the user can reduce the dissatisfaction caused by the washing time.
