The existing full-automatic pulsator washing machine generally works in a mode that when washing and rinsing are carried out, the driving device drives the pulsator of the washing machine to rotate positively and negatively through the decelerating clutch device, and when dewatering is carried out, the driving device drives the pulsator of the washing machine and the washing barrel to rotate synchronously at high speed through the decelerating clutch device.

However, with the high-speed development of technology, the improvement of the washing effect of the existing full-automatic pulsator washing machine is more limited by simply relying on the washing mode of pulsator stirring water flow, so that how to increase the washing diversity of the full-automatic pulsator washing machine to improve the washing effect becomes a technical problem to be solved urgently.

Several patents have proposed solutions to this problem, for example, application number: 02804912.8, a chinese patent of the invention, entitled a transmission mechanism for producing bi-directional rotation, a washing machine and method for producing bi-directional washing, and related inner tub and agitator, discloses a transmission mechanism for producing bi-directional drive suitable for use in a washing machine, 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 of the power output end is connected with an inner barrel shaft (11) and enables the inner barrel shaft to rotate in a second direction opposite to the first direction. A washing machine for producing bidirectional washing and a washing method capable of producing bidirectional washing in the washing machine. A pulsator and an inner tub for a washing machine. The patent discloses a transmission mechanism capable of enabling a washing machine to generate bidirectional driving, and meanwhile 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 that the power driving mode is single when the existing full-automatic pulsator washing machine washes, but the disclosed transmission mechanism is complex in structure, high in manufacturing and assembling difficulty, high in manufacturing cost and the like.
