When the preset water volume is reached, the washing machine starts to enter the washing state. Since the upper clutch sleeve and the clutch sleeve are in a fixed state, the power of the input shaft passes through the planetary The deceleration of the gear train is transmitted to the pulsator shaft and the pulsator to realize the washing state.

At the end of washing, the traction motor drives the lower fork lever downward to move the lower clutch sleeve down, disengages from the lower fixed sleeve, and engages with the lower movable sleeve, so that the input shaft, the lower shaft sleeve, the brake wheel, and the middle shaft sleeve Connect with the sealing water tray again, at this moment, the upper clutch sleeve, the outer shaft sleeve, the washing bucket, etc. are still in a fixed state. The frequency conversion motor drives the input shaft, the lower bushing, the brake wheel, the middle bushing and the sealing water pan to rotate clockwise for an angle, controlled by the position sensor, so that the drain hole of the sealing water pan is facing the drain hole of the flange for drainage.

When the drainage is finished, the traction motor pulls the upper shift fork lever to rotate, so that the upper clutch sleeve is separated from the upper fixed sleeve and meshes with the upper movable sleeve. , to drive the pulsator, water sealing plate, and the washing bucket and flange to rotate together to achieve the dehydration state.

There are three states in the whole washing process.

The first state is that the upper clutch sleeve is engaged with the upper fixed sleeve, and the lower clutch sleeve is engaged with the lower fixed sleeve. Then, the lower shaft sleeve, the brake wheel, the middle shaft sleeve, and the outer shaft sleeve are all in a fixed state, which is also a washing bucket. , the flange and the sealing water plate do not move, and when the motor drives the input shaft to rotate, the planetary gear train drives the pulsator shaft and the pulsator to rotate at reduced speed. In the washing state.

In the second state, the upper clutch sleeve is engaged with the upper movable sleeve, and the lower clutch sleeve is engaged with the lower movable sleeve, and furthermore, the input shaft, the lower shaft sleeve, the brake wheel, the middle shaft sleeve, the outer shaft sleeve and the pulsator shaft are all as one.
