Abstract
In the initial stage of the dehydrating operation (spin cycle) in a washing machine, operations of rotating the dehydrating tank at a low speed for a predetermined period of time or of stopping the driving motor temporarily when the speed of rotation of the dehydrating tank reaches a predetermined low value are repeated a plurality of times. During this operation, the water contained in the clothes in the dehydrating tank is partly removed and the weight of the load decreased as much. Therefore, in a dehydrating operation in which the tank is rotated at a high speed, the clothes do not have a strong tendency to shift to one side, with the result that little vibration and noise are produced.
