The washing process of the present washing machine is generally divided into four sections of a washing stage, an intermediate dehydration stage, a rinsing stage and a final dehydration stage. For the washing program of the current washing machine, the dehydration link is a link with larger power consumption in the washing machine process. However, at present, the dewatering time and the dewatering speed are constant for a specific washing program. The inventors of the present invention have studied and found that the moisture content of some clothes made of materials having a low water absorption rate or the amount of the clothes is small, and the requirement of the moisture content can be met in a short dehydration time. Therefore, under appropriate conditions, the dewatering time is shortened, the washing time can be saved, and the power consumption can be reduced.
