Abstract

The present invention comprises the steps of detecting unbalance as a dehydration progress control method of the washing machine, and if the detected unbalance amount is within a certain range, the dehydration proceeds after the intermittent dehydration corresponding to the quantity detection amount.

Description

Dehydration progress control method of washing machine

1 is a flow chart of a dehydration progress control method of a conventional washing machine.

2 is a pattern diagram of a dehydration rotation speed according to a dehydration progress control method of a conventional washing machine.

3 is a flow chart of the dehydration progress control method of the washing machine of the present invention.

4 is a pattern diagram of the dehydration rotation speed according to the dehydration progress control method of the washing machine of the present invention.

The present invention relates to a dehydration progress control method of a washing machine, and more particularly, to a dehydration progress control method of a washing machine to prevent abnormal vibration of the initial stage of the dehydration by controlling the intermittent dehydration time in accordance with the amount of detection of the amount of water.

In the general automatic settler, when the washing stroke is completed, the drain valve is turned on to drain the water, and when the draining is completed, the washing motor is restarted to rotate the dehydration tank to drain the water through the drain valve. Dehydrate

When the dehydration stroke as described above in more detail, when the drainage is completed after the completion of the washing stroke, the drain stroke is completed, first, by turning on the motor for a predetermined time to slowly rotate the dehydration tank to less than 100rpm to detect the unbalance. At this time, the on-balance of the safety switch, which is an unbalance detecting means, is set to zero and an unbalance is detected. If the on-count of the switch generated during the unbalance is more than a predetermined number of times, it is determined that the unbalance error stops dehydration.

That is, as shown in FIGS. 1 and 2, when the unbalance detection frequency is 1-7 and the unbalance amount is less than 500g, the fast dewatering stroke is performed at a high speed. When the unbalance amount is 500g or more, the unbalance is continuously detected. Is 8-10, if the unbalance amount is less than 500g, the high speed dewatering stroke is performed. If the unbalance amount is less than 500g and less than 1350g, the standard dewatering process is performed at about 650rpm. It will be judged as an error.

By the way, in the progress of the dehydration administration as described above, there is a problem that can not prevent the difference caused by the amount of laundry cloth, that is, abnormal vibration caused during the transition period of the initial startup, especially when dehydrating laundry with a large residual ratio There was a problem that can not prevent the abnormal vibration in the process of fast dehydration without falling out.

The present invention is to solve the problems of the prior art, it is an object of the present invention to provide a dehydration progress control method of the washing machine that can prevent abnormal vibration of the initial stage of the dehydration by controlling the intermittent dehydration time according to the amount of detection of the amount.

In order to achieve the above object, the dehydration progress control method of the washing machine of the present invention, the step of detecting the amount of unbalance, and if the detected unbalance amount is within a certain range after the intermittent dehydration corresponding to the quantity detection amount is dehydrated Characterized by having a step to proceed.

Hereinafter, the dehydration progress control method of the washing machine of the present invention will be described in detail with reference to the accompanying drawings.

Dehydration progress control method of the washing machine of the present invention, as shown in Figure 3, the step of detecting the amount of unbalance, and if the detected unbalance amount is within a certain range after the intermittent dehydration corresponding to the quantity detection amount Dehydration takes place.

On the other hand, the degree of the intermittent dehydration is to increase the time of the intermittent dehydration in proportion to the large, medium and small of the quantity detection amount.

That is, as shown in FIGS. 1 and 2, when the drainage is completed after the washing stroke is completed, the drainage stroke is completed. First, the motor is turned on for a predetermined time to slowly rotate the dehydration tank to less than 100 rpm to detect unbalance. do. At this time, the unbalance detection means detects the unbalance by setting the on number of the safety switches to zero, and if the number of times of the switch generated during the unbalance is more than a predetermined number of times, the debalance error is determined to stop dehydration.

That is, if the unbalance detection frequency is 1-7 and the unbalance amount is less than 500g, or the unbalance amount is more than 500g, it continues to detect the unbalance and the unbalance detection frequency is 8-10 and the unbalance amount is less than 500g or the unbalance amount is less than 500g or less than 1350g, If the detected amount is small, intermittent dehydration is performed for 20 seconds. If the quantity is detected, intermittent dehydration is performed for 30 seconds. If the amount is detected, intermittent dehydration is performed for 40 seconds.

On the other hand, if the number of unbalance detection times is 10, and the unbalance amount is 1350g or more, dehydration is stopped by determining an unbalance error.

As described above, according to the present invention, when the unbalance is detected, intermittent dehydration corresponding to the quantity detection amount can be prevented, thereby making it possible to prevent the difference caused by the washing amount of the laundry somewhat, that is, the abnormal vibration occurring during the transient period of initial startup. .

Claims (2)

And detecting the unbalance, and performing the dehydration after the intermittent dehydration corresponding to the quantity detection amount if the detected unbalance amount is within a predetermined range. The method of claim 1, The dehydration progress control method of the washing machine, characterized in that to increase the time of intermittent dehydration in proportion to the amount of detected amount.
