Description

How to Rinse and Rinse the Washing Machine

The present invention relates to a dehydration rinsing method of a washing machine, and in particular, when dewatering after washing or rinsing, the dehydration rinsing while releasing the laundry adhered to the wall surface of the washing tank by supplying the laundry adhered to the wall surface of the washing tank by the rotary centrifugal force of the washing tank. The present invention relates to a dehydration rinsing method of a washing machine in which the water to be supplied is dewatered while being evenly sprayed to the laundry of the washing tank.

In general, dehydration rinsing during the administration of the washing machine is the washing and rinsing is made while the kink between the laundry due to the washing water flow friction during washing or rinsing.

In this way, when dehydration after washing or rinsing is completed while the laundry is twisted, the laundry in which the twist occurs is dewatered by being biased to one side of the washing tank, and is dehydrated while being closely adhered to the wall of the washing tank by the rotary centrifugal force. When the washing tank is unbalanced (eccentric) is generated not only causes vibration noise by this unbalance, but also has a problem that even damage the washing machine.

Therefore, in the related art, in order to release unbalance due to twisting of laundry during washing or rinsing during dehydration, the washing tank is dehydrated while rotating at a predetermined rotation speed and watered to release the water from the washing water to close or twist the wall of the washing tank. However, since the washing water supplied to release the laundry is dehydrated while controlling the speed by intermittently operating the washing tank during the dehydration, the washing tank is dehydrated while moving up and down around the reference speed. Changes in dehydration rotation occurs so that it is not evenly sprayed on the laundry of the washing tank and is intensively sprayed only on a specific part, which causes a problem of dehydration rinse.

An object of the present invention is to dehydrate while supplying to the laundry close to the wall of the washing tank by the centrifugal force of the washing tank when the dehydration rinsing after washing or rinsing completion, so that the washing water is evenly sprayed to the laundry close to the wall of the washing tank during the dehydration rinsing It is intended to be able to improve the degree of dehydration rinsing.

In order to realize the above object, the present invention is to set the rotating washing tank at predetermined intervals when washing and rinsing is completed during a series of washing operations, and the rotational speed is measured for each section of the divided washing tank. In the section in which the measured rotational speed of each section is slower than the predetermined rotational speed, the water supply amount is reduced.

On the other hand, if the rotational speed of each section (AD) is less than the preset rotational speed, retrospective water supply step 36 for retroactively supplying the water supply, and the retrospective Dehydration is completed in the dehydration completion step 37 to determine whether the dehydration is completed while the dehydration is completed while the water supply to the retrograde water in the water stage 36 is completed.

Referring to the operation of the present invention made as described above are as follows.

First, the power is supplied to the washing machine, and the laundry to be washed is put in the washing tank 2 equipped with the permanent magnet 6 in the section partitioned at a predetermined interval on the outer wall, and the operation signal input unit (A) When the washing stroke of the user is set and inputted to the microcomputer (b), the microcomputer (b) controls the driving signal input from the driving signal input unit (a) by the predetermined program according to the predetermined program. When the driving signal for a series of washing administrations is input from the driving signal input unit (A), the microcomputer (b) goes to the washing step 30 and the washing amount is input. Determine the water level for, and if the water level is determined to control the water supply driving unit (c) to supply water to the water level determined in the washing tank (2), the water level is water level detection unit ( (D) When water is supplied through the sensing and the water supply is completed, the microcomputer (b) performs the washing while controlling the motor 5 through the motor driving part (e) while rotating the pulsator 3 forward and backward.

While the washing proceeds as described above, the microcomputer (b) proceeds to the laundry while frequently determining whether the washing is completed, and when the washing administration is completed, go to the rinsing step 31 and supply water to the determined water level in the washing tank 2. The motor 5 is controlled through the motor driving part e to rinse the pulsator 3 while the pulsator 3 is rotated forward and backward, but the rinsing is performed a predetermined number of times.

As the rinsing proceeds as described above, when the rinsing is completed, the microcomputer (b) goes to the dehydration step 32 to control the motor 5 through the motor driving part e to rotate the washing tub 2 in one direction to proceed with dehydration. In addition, the microcomputer (b) is to go to the water supply step 33 to release the laundry adsorbed on the wall of the washing tank (2) when dewatering to control the water supply and drain drive (C) to supply water to the washing tank (2). .

As the water supply proceeds as described above, the microcomputer (b) goes to the rotational speed detection step 34 for each section and controls the rotational speed detection unit (bar) for each section of the washing tank 2 through the hall sensor 7 ( The rotating speed is detected with respect to the permanent magnet 6 that is mounted on the section partitioned by AD), and the detected rotational speed for each section AD is input to the microcomputer (b).

Therefore, the microcomputer (b) goes to the step of determining the rotational speed of each section 35 and determines whether it is slower than the predetermined rotational speed with respect to the detected rotational speed of each section (AD), but the first section (AB) (BC) (CD) (DA) in turn determines whether it is slower than the predetermined predetermined rotation speed, go to the retrospective water supply step (36) for the section with a slow rotation speed for each section, The control proceeds to dehydration while reducing the amount of the wash water being supplied to the water supply, and then proceeds to the dehydration completion determination step 37 to determine whether the ongoing dehydration is completed from the dehydration step 32 until dehydration is completed. When the dehydration rinsing is performed repeatedly to wash water in the laundry in the washing tank (2) evenly.

As described above, according to the present invention, when washing and rinsing are completed in a series of washing strokes, the rotating washing tub is partitioned at predetermined intervals during dehydration, and the rotational speed is measured for each section of the set washing tub. In the section where the rotational speed of each section is slower than the predetermined rotational speed, the water supply is made less by supplying water, so that the washing water is evenly sprayed on the laundry closely adhered to the wall of the washing tank during the dehydration rinsing, thereby improving the dehydration rinsing degree. It will provide an effect.
