Background

The washing machine, as a household appliance, is gradually becoming an indispensable part of people's life, and the full-automatic pulsator washing machine, as a main type of washing machine, has an increasingly wide application range. The prior full-automatic impeller washing machine generally has the working mode that during washing and rinsing, a driving device drives an impeller of the washing machine to rotate forward and backward through a speed reduction clutch device, and during dehydration, the driving device drives the impeller of the washing machine and a washing barrel to synchronously rotate at high speed through the speed reduction clutch device.

However, with the rapid development of science and technology, the existing full-automatic pulsator washing machine has a more limited improvement of the washing effect of the clothes by simply using a washing mode of pulsator stirring water flow, and therefore, how to increase the washing diversity of the full-automatic pulsator washing machine becomes a technical problem which needs to be solved urgently to improve the washing effect.

Several patents have been proposed to solve this problem, such as the following: 02804912.8 entitled Transmission mechanism for generating bidirectional rotation, washing machine and method for generating bidirectional washing, and related inner tub and agitator, which discloses a transmission mechanism suitable for use in a washing machine for generating bidirectional drive, comprising a power input and two power outputs, one of which is connected to an agitator shaft (10) and rotates the agitator shaft in a first direction; and the other power output end thereof is connected with an inner barrel shaft (11) and rotates the inner barrel shaft in a second direction opposite to the first direction. A washing machine for generating bi-directional washing and a washing method capable of generating bi-directional washing in the washing machine. A pulsator and an inner tub for a washing machine. The patent discloses a transmission mechanism capable of driving a washing machine bidirectionally, and simultaneously discloses a specific structure of the transmission mechanism in the specification, and the content of the specification and the attached drawings shows that the patent solves the problem of single power driving mode of the existing full-automatic pulsator washing machine during washing to a certain extent, but the disclosed transmission mechanism has the problems of complex structure, high manufacturing and assembling difficulty, high manufacturing cost and the like.

For another example, application No.: 201310408108.X, with the name: the invention discloses a full-automatic washing machine, which comprises an outer barrel, an inner barrel, a wave wheel and a driving device, wherein the driving device comprises at least two rotors and at least one stator, one of the rotors is connected with the inner barrel shaft, and the other rotor is connected with the wave wheel shaft; the driving device is a variable frequency direct drive motor, the rotor, the stator, the inner barrel shaft and the impeller shaft are coaxially arranged, the inner barrel shaft is hollow, and the impeller shaft is arranged in the inner barrel shaft; when the washing machine washes, the wave wheel and the inner barrel rotate in the same direction, or rotate in opposite directions, or one of the wave wheel and the inner barrel rotates, and when the washing machine dehydrates, the wave wheel and the inner barrel rotate in the same direction and at the same speed. The washing machine is connected with the inner barrel shaft and the impeller shaft through the two rotors respectively, and the inner barrel and the impeller are driven to rotate through the double rotors respectively, so that the structure reduces the weight, the volume and the cost of a driving system to a great extent, and improves the transmission efficiency and the stability.

From the two published patent applications mentioned above, there are two main concepts to solve the water flow diversity of washing machines: the method comprises the following steps that firstly, a speed reduction clutch device capable of outputting bidirectional power is designed to realize bidirectional washing in the washing process of the washing machine, and the water flow effect is enhanced; and the second mode is to design a driving motor with bidirectional power output, and respectively drive the impeller and the inner barrel to realize bidirectional washing in the washing process of the washing machine, so that the water flow effect is enhanced. The first mode has the defects of complex structure, difficult installation and complex control method of the speed reduction clutch device, and the second mode has the defect of high cost of the driving motor with bidirectional power output.

In addition, the mode that the multiple washing modes of the washing machine are switched by adopting the speed reduction clutch device is adopted, and the clutch mechanisms of the speed reduction clutch device are required to be respectively kept in the meshing states corresponding to the multiple washing modes, so that the meshing states corresponding to the multiple washing modes are switched by adopting the multi-stroke motor to drive the clutch mechanisms, but the clutch mechanisms cannot be locked by the multi-stroke motor, and the meshing stability of the clutch mechanisms is poor.
