BACKGROUND OF THE INVENTION A conventional washing machine has a structure consisting of an inner tub, an outer tub, an agitator, a transmission system, a control system, and The casing and the like. During washing, the inner bucket does not rotate, and the agitator rotates in the forward and reverse directions, which drives the water and clothes in the bucket to rotate for washing. The washing method has been tested in practice and found some defects: 1. The washing method is single, and the washing ratio is difficult to improve; 2. The strength of the water flow is weak, and the clothes are prone to entanglement. In order to overcome the above-mentioned shortcomings, some washing machine manufacturing companies have designed a "rotating bucket" washing machine. The method is that when washing, the inner bucket is in a free state. The agitator rotates in the reverse direction to achieve the purpose of "washing clothes". However, this method still has shortcomings. Because the inner bucket has no power, the rotation force of the inner bucket is small, and the stirrer is only reversed on the bottom surface of the bucket. The effect of "washing" is not large, and the washing effect is not obvious, and it is still not very good. Solve the problem of clothing entanglement. How to overcome these shortcomings as soon as possible is an urgent problem.
