[0026] During dehydration operation: the dehydration shaft is in a free state, the clutch shaft is stuck, and the input shaft 1 is stuck.

[0027] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] Below, combined with the attached Figure 1 , specifically describe the operating status of each working condition.

[0029] Combined with Figure 1 A clutch device (not shown) is provided at the clutch position of the clutch shaft input end 201. The clutch device can slide up and down at three positions: upper, middle and lower on the surface of the clutch shaft input end 201 under the control of the washing machine computer board program.

[0030] During the washing operation, the clutch device is in the upper gear position. At this time, the clutch shaft input end 201 and the dehydration shaft input end 301 are engaged with the housing of the washing machine clutch under the action of the clutch device and remain stationary. The input shaft 1 is completely separated from the clutch device and is in a free state. It rotates in both directions under the action of the input power and is output to the washing shaft 4 through the deceleration transmission power component to wash the clothes. This is the connection state of the clutch device during the washing operation.

[0031] When the clutch device moves downward to the mid-range position under the action of external force, the dehydration shaft input end 301 is still engaged with the housing of the washing machine clutch and remains stationary. The input shaft 1 and the clutch shaft input end 201 are both in a free state and can rotate freely. The power at the input shaft 1 end drives the clutch shaft output end 202 to rotate an angle under the action of the gear train, opening the drain valve to drain water. This is the connection state during the drainage condition.

[0032] When the clutch device is acted upon by external force and slides downward to the lower position, the clutch device completely meshes the clutch shaft input end 201 with the input shaft 1 as a whole. At this time, the dehydration shaft input end 301 is completely separated from the shell and is also in a free state. The input power connects the dehydration shaft 301, the clutch shaft input end 201 and the input shaft 1 as a whole. This is the connection state of the clutch device during the dehydration condition.

[0033] When dehydration is finished, the clutch device returns to the middle position under the action of external force, and the clutch device engages the dehydration shaft input end 301 with the shell to keep it stationary. The clutch shaft input end 201 and the input shaft 1 are in a free state and can rotate relative to each other. Under the action of the computer board program, the input shaft 1 and the clutch shaft input end 201 rotate in the opposite direction by an angle, and under the action of the gear train, the washing shaft 4 and the clutch shaft output end 202 are driven to rotate in the opposite direction by an angle, and the drain valve is closed. At this time, it is the connection state when the drain hole is closed.

[0034] When the clutch device returns to the initial position under the action of external force, the clutch device drives the dehydration shaft input end 301 and the clutch shaft input end 201 to fully engage with the shell and remain stationary, completely disengaging from the input shaft 1 and returning to the connection state during the washing condition.

[0035] As some embodiments of the present invention, the clutch device can slide axially to three positions: upper, middle and lower under the action of an external pusher claw. The external pusher claw controls the axial movement of the pusher claw to three positions: upper, middle and lower through a lever fulcrum. An external traction motor pulls one end of the pusher claw, and the pusher claw at the other end of the fulcrum is connected to the clutch device.

[0036] The above is a detailed introduction to the three-axis input and three-axis output washing machine deceleration clutch provided by the present invention.
