This patent discloses a transmission mechanism that can make the washing machine drive in both directions, and at the same time, the specific structure of the transmission mechanism is disclosed in the description. It can be seen from the content of the description and the drawings that this patent solves the existing problems to some extent. The automatic pulsator washing machine has the problem of a single power driving mode during washing, but the disclosed transmission mechanism has the problems of complex structure, high manufacturing and assembly difficulty, and high manufacturing cost.

Another example is the application number: CN201310408108.X, the name is: Chinese invention patent application for automatic washing machine, the invention discloses a fully automatic washing machine, including an outer tub, an inner tub, a pulsator and a driving device, and the driving device includes At least two rotors and at least one stator, one of which is connected to the inner barrel shaft, and the other is connected to the pulsator shaft; the drive device is a variable frequency direct drive motor, and the rotor, stator, inner barrel shaft and pulsator shaft are coaxial set, the inner barrel shaft is hollow, and the pulsator shaft is arranged in the inner barrel shaft; the pulsator and the inner barrel rotate in the same direction when the washing machine is washed, or rotate in the opposite direction of each other, or one of the pulsator and the inner barrel rotates, and the pulsator and the inner barrel rotate during dehydration.

At this time, the drain motor does not open, and neither the brake lever nor the drain valve operates (no drain).

The brake wheel of the existing fully automatic washing machine is in a braking state when washing, and the deceleration clutch device can only drive the pulsator to rotate. During dehydration, although the brake wheel can rotate, it can only maintain one direction under the limitation of the one-way bearing. Rotation, which greatly restricts the inner tub from rotating during the washing process, or even if it rotates, the rotation mode is relatively simple, which is not conducive to the formation of a variety of washing methods.

The braking wheel of the deceleration clutch device in this embodiment can rotate in both directions, thereby driving the inner tub to have more rotation modes, and theoretically, it can provide more washing modes: by controlling the clutch drive device, the clutch sleeve is driven to engage with the fixed sleeve, and the input shaft is engaged and fixed. The sleeve 13 is locked, and the brake wheel is also locked at the same time, the washing method of decelerating the clutch device to drive the rotation of the pulsator; by controlling the clutch drive device to drive the clutch sleeve to separate from the fixed sleeve and not engage and fix with the torque transmission sleeve, the input sleeve 13 Unlocking, the brake wheel can rotate freely in both directions, the deceleration clutch device single-drives the pulsator to rotate, and the inner barrel rotates freely.

Therefore, the deceleration clutch device of this embodiment can provide various washing functions: the previous fully automatic washing method can be adopted, and the hand rubbing washing method can also be adopted. That is, when washing: it can provide a washing method in which the pulsator rotates and the inner barrel does not rotate, or a washing method in which the pulsator rotates and the inner barrel rotates freely. During the entire washing process of the washing machine, a variety of combined washing methods, multiple water flows, and cyclic cross washing modes can be used to run the washing method, which makes the washing more sufficient, the clothes are cleaner, and the clothes are not entangled, and the user experience is improved.
