Abstract

The present invention relates to a method for removing unbalance that occurs when a washing machine is dewatered to remove unbalance caused by unbalance of laundry in a washing tank during dehydration of a washing machine, .

When the unbalance of the conventional washing machine is generated during the dehydration process, the amount of washing water used for washing is increased. Therefore, the amount of consumption is increased by about 20% based on four times of rinsing and the washing time is increased. .

In order to solve such a problem, the present invention solves this problem without re-supplying water when unbalance occurs in the washing tub during dewatering, thereby reducing washing water used for washing and also reducing power consumption by shortening washing time .

Description

Unbalance elimination method in dehydration of washing machine THE UNBALANCE DISSOLVED SYSTEM TO OCCURED DURING A DRY

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for removing unbalance that occurs when a washing machine is dewatered, and in particular, an unbalance caused by a bias of laundry in a washing tub is removed during dehydration of the washing machine.

1 is a perspective view of a washing machine according to a first embodiment of the present invention; FIG. 2 is a perspective view of a washing machine according to a first embodiment of the present invention; A motor 5 as a power source located at a lower end of the outer tub 2; a clutch 6 for switching the washing and dewatering; a lower end of the dehydrating tub 3; An unbalance sensor 8 for detecting a bias of the laundry 7 in the dewatering tank 3 and a water level sensor 8 for sensing the level of the washing water, (9), reference numeral 3A denotes a dehydrating tank wall surface, and reference numeral 10 denotes a water supply valve.

The operation of the general washing machine constructed as described above will be described below. First, the power generated by the rotation of the motor 5 causes the laundry 7 to rotate at a high speed together with the dewatering tank 3 through the clutch 6.

The washing water 7 contained in the washing tub 7 may be deflected by the high speed rotation of the dewatering tank 3 to cause the outer tub 2 located outside the dewatering tank 7 to hit the washing tub 7, So that the outer tub 2 vibrates.

The vibration is sensed by the unbalance sensor 8 located at the upper end of the outer case 1 due to the severe vibration of the outer tank 2. [

The unbalance elimination step that occurs when the washing machine is dehydrated in the conventional washing machine will be described with reference to FIGS. 1 and 2.

A first step of stopping dewatering when unbalanced during dehydration occurs and then re-supplying the dehydrated water through the water supply valve (10) to a level set in the dehydrating tank (3) containing the laundry (7) A second step of uniformly dispersing the laundry 7 by rotating the motor 5 in a mode for evenly dispersing the laundry 7 when the water supply is completed; and a second step of uniformly dispersing the laundry 7 in the second step, And a fourth step of starting rehydration when the drainage of the third stage is completed.

1 and 2 illustrate the steps of eliminating the unbalance of the conventional washing machine constructed as described above. Referring to FIGS. 1 and 2, when the washing water 7 in the dewatering tank 3 is deflected by the high- When the balance phenomenon is detected by the unbalance sensor 8, the dewatering is stopped, and then the water is re-supplied to the dewatering tank 3 through the water supply valve 10 as shown in FIG.

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

The washing water 7 in the dewatering tank 3 is uniformly dispersed by the rotation of the motor 5. When the laundry 7 in the dewatering tank 3 is uniformly dispersed, drainage is started, Dehydration begins.

In the conventional washing machine, when unbalance occurs in the dehydrating tank in the dehydrating tank, the washing water in the dehydrating tank is rehydrated, the motor is rotated to uniformly disperse the laundry, and then the dehydrating starts after draining.

However, as described above, the water consumption due to the re-supply of water during the dehydration is increased by about 20%, and the longer the washing time, the more the power consumption is increased.

In order to solve the above-described problems, the present invention provides a laundry washing machine and a pulsator that repeatedly rotate and stop the laundry without containing water during rehydration when the unbalance occurs in the washing tub during dewatering, It is possible to reduce the number of water, the washing time and the power consumption, so that it can solve the complaint of the consumer.

The steps of eliminating unbalance in the washing machine according to the present invention will be described with reference to FIGS.

A first step of suddenly stopping the pear cleater 4 and the dehydrating tank 3 by simultaneously rotating the laundry 7 when the dehydrating laundry 7 is accumulated on one side of the dehydrating tank 3, A second step of suddenly stopping the weakened laundry 7 by turning the spinning direction of the dewatering tank 3 in a reversed direction and repeating the steps of the first and second steps a predetermined number of times, A fourth step of uniformly dispersing the laundry 7 by rotating only the pulsator 4 when the laundry 7 is evenly dispersed after the third step; And a fifth step of performing dehydration if the laundry 7 in the tub 3 is uniformly dispersed.

The steps of eliminating unbalance in the thus configured washing machine of the present invention will be described with reference to FIGS. 3 and 4.

When the unbalanced phenomenon occurs in which the outer tub 2 is severely hit by the deflection of the laundry 7 during dehydration, the dehydration tank 3 and the pulsator 4 containing the laundry 7 are simultaneously rotated And then suddenly stop.

As described above, when the laundry 7 is rotated and then stopped, the laundry 7 continues to rotate with inertia and the friction between the laundry 7 is different according to the position of the laundry 7, And the bias is reduced.

At this time, when the washing water 7 having a reduced bunching is changed in the rotating direction and the spinning water tank 3 is suddenly stopped after the spinning water tank 3 is rotated, the bunching of the laundry 7 is weakened and the unevenness is reduced.

When the dewatering vessel 3 containing the laundry 7 is repeatedly rotated and stopped about four times in each direction by the above process, the laundry 7 is uniformly dispersed to one side as shown in FIG. 3 do.

When the laundry 7 is dispersed to one side, only the pulsator 4 is rotated to disperse the laundry 7 as shown in FIG. 4, and the laundry 7 in the dewatering vessel 3 If dehydration is performed after dispersing, unbalance due to the laundry 7 will not occur.

As described above, according to the present invention, the unbalance of the laundry occurring when dewatering the washing machine is repeatedly rotated and stopped while changing the rotating direction of the washing tub, thereby reducing the unbalance of the laundry, And the power consumption due to the washing time is reduced, so that the user can reduce complaints caused by the washing time.
