The invention provides a washing
machine speed reduction clutch device, a washing
machine and a control method thereof.The washing
machine speed reduction clutch device comprises a
clutch mechanism, the clutch mechanism comprises a clutch sleeve and a shifting fork
assembly, the clutch sleeve can reciprocate to conduct clutch switching, the shifting fork
assembly drives the clutch sleeve to move, and the shifting fork
assembly comprises a shifting fork and a shifting fork driving device; one end of the shifting fork is connected to the clutch sleeve in a forked mode, the shifting fork driving device comprises a
power component and a gear and rack transmission mechanism, and the rotating output end of the
power component is in transmission connection with the other end of the shifting fork through the gear and rack transmission mechanism. And the power part drives the shifting fork to shift the clutch sleeve to do
reciprocating motion through the gear and rack transmission mechanism to perform clutch switching. The rotation output of the power part of the washing machine
speed reduction clutch device is converted into
reciprocating motion in the vertical direction through the gear and rack transmission mechanism to drive the shifting fork to stir the clutch sleeve to do
reciprocating motion for clutch switching, and the stability of the washing machine speed reduction clutch device in the working process is improved.
