(B) Prior Art When this type of washing machine is used at a coin laundry or the like by inserting a coin, it is often done so that abnormal vibrations during the spin-drying process are not detected. That is, even if abnormal vibration occurs, the operation continues without abnormality, and this is because various troubles will occur if the operation is stopped due to the abnormality. This caused dents in the machine frame and loud noises.

One method for eliminating abnormal vibrations and obtaining a dehydrating effect is to automatically return to the rinsing process once abnormal vibrations are detected to eliminate unevenness of the laundry, and then restart dehydration. However, this method takes a long time and uses a large amount of water, making it difficult to adopt from a business standpoint.

However, in this case, although the dents and the like are eliminated, there is almost no dehydration effect, and when the laundry is finally taken out, the water contained therein sometimes drips onto the feet.

(E) Effect: In other words, the motor (washing and spin-drying tank), which is continuously operating for centrifugal dehydration during the dehydration process, is intermittently rotated to increase the actual number of revolutions in response to the arrival of multiple abnormal vibration detection signals. Drop it to reduce the impact force.
Then, dehydration is performed little by little during intermittent rotation,
If an abnormal vibration detection signal does not arrive within a predetermined period of time, continuous rotation is resumed to increase the dehydration effect. Here, if the detection signal arrives again, the intermittent rotation will naturally be resumed.

In this way, fully automatic operation starts with water supply and washing,
During the process, there is drainage, intermediate dehydration, rinsing, and then drainage and final dehydration, and the process is complete. Here, the drainage and dewatering steps will be explained. When the washing and rinsing time is over, the microcomputer 22 stops the motor 7, opens the drain electromagnetic valve 10, and operates the clutch 26. When the water level in the tank drops to a considerably low level and the water level detection switch 13 is reset, the microcomputer 22 continues to operate until the vibration detection switch 17 is activated by abnormal vibration or the lid switch 20 is activated by opening the top lid 19. The motor 7 is rotated clockwise at a high periodic speed (approximately 800 rpm) by the circuit 25, and the dehydration tank 4 and the rotary blade 6 are rotated at high speed in one direction to perform so-called centrifugal dehydration.

If the outer tub 3 vibrates abnormally during spin-drying, especially at the beginning of rotation, due to unevenness of the laundry, etc., the vibration detection switch 17 detects this and outputs a detection signal.
This switch 17 is of an automatic return type and outputs a detection signal any number of times each time abnormal vibration occurs.

On the other hand, the microcomputer 22 counts the number of detection signals that have arrived, and determines that an abnormal vibration state is present when, for example, five detection signals are input. Therefore, you can leave it as it is or use the motor 7.
After stopping the , try the trigger from 1 to
The rotation is performed every 2 Hz, and by intermittent rotation of the motor 7, the actual rotational speed is set to about 300 rpm.
This rotational speed is such that the outer tank 3 hardly hits the machine frame 1.

For example, during intermittent rotation such as energization for 3 seconds and de-energization for 3 seconds, the dehydration tank 3 rotates slowly and drains the laundry little by little, but the microcomputer 22 is configured so that vibration detection signals can continue to be input. There is. Then, the microcomputer 22 measures time T using a counter when switching to intermittent rotation, and checks whether a detection signal arrives within this time T. This time T
When even one detection signal is input, the counter is cleared and the time measurement and signal arrival are repeatedly checked.
Continue intermittent rotation. On the other hand, when the detection signal does not arrive within time T, intermittent rotation is stopped and switched to continuous rotation. Then, the above operation is repeated.

(g) Effects of the invention According to the invention, when abnormal vibration is detected during the dehydration process, instead of completely stopping dehydration, it is possible to dehydrate the machine frame little by little without damaging the machine frame. When abnormal vibrations no longer occur due to a reduction in the water load, continuous dehydration can be performed again to increase the dehydration effect. Therefore, it is possible to provide an extremely practical washing machine, which eliminates the problem of water dripping from the laundry at the end of washing, which is difficult to dispose of.
