Dewater control method of washing machine

Abstract

The invention provides a dehydration control method for washing machine capable of making an automatic operation effective by not perfectly stopping dehydration operation immediately when an impact value is small even if an unbalance detection switch is operated to judge an unbalance state in dehydration process. The washing machine for automatically progressing washing, rinsing and dehydration processes provided with an abnormal vibration detecting means for detecting an abnormal vibration generated by the large gathering to one side of clothes within a washing and spinning tub in dehydration process, is further provided with a detection frequency measuring means for measuring the detection frequency of abnormal vibration and a rotating speed detecting means for detecting the spinning rotating speed for dehydration. The value of detecting frequency of abnormal vibration is set on the basis of the value of the spinning rotating speed, and when the detection frequency of abnormal vibration reaches the set value thereof, the dehydration operation is stopped.

Description

technical field [0001] The invention relates to a dehydration control method of a washing machine. Background technique [0002] For example known fully automatic washing machine also as figure 2 As shown, in the outer tub 1, the water tub 4 is freely swayably suspended by the suspension rod 2 and the anti-vibration part 3. In the water tub 4, a washing and dehydrating tub 5 having a rotating wing at the bottom is rotatably arranged. The drive device 7 using a motor etc. is arrange|positioned below 4. [0003] This fully automatic washing machine automatically performs water supply, laundry, washing, and dehydration procedures. When the dehydration operation is performed when the washing and dehydrating bucket is rotated at a high level, if the laundry in the washing and dehydrating bucket 5 deviates in one direction, the washing The shaking and noise transmission of the dehydration bucket 5 and the water bucket 4 will cause the water bucket 4 to vibrate and cause the whol...

[0003] This fully automatic washing machine automatically performs water supply, laundry, washing, and dehydration procedures. When the dehydration operation is performed when the washing and dehydrating bucket is rotated at a high level, if the laundry in the washing and dehydrating bucket 5 deviates in one direction, the washing The shaking of the dehydration bucket 5 and the noise transmission to the bucket 4 should cause the vibration of the water bucket 4 to cause abnormal vibration of the whole washing machine through contact with the outer shell of the washing machine, so that the dehydration operation cannot be carried out, and in the worst case, the washing machine may even fall down.
