[0044] The washing machine is provided with a clutch claw, and the clutch claw is connected to the double-stroke tractor. The lower clutch device 10 can be fixed in three positions, namely, upper position, middle position and lower position, from the top to the bottom of the washing machine under the action of the external clutch claw. Fig. 9 The clutch finger adjusts the position of the lower clutch device 10 under the action of the traction device, so that the outer clutch sleeve 1003 and the inner clutch sleeve 1001 are respectively in different positions, thereby controlling the relationship between the input shaft 11, the intermediate shaft 13 and the clutch shaft 12. The position relationship between the upper clutch sleeve 10 and the clutch wheel 5 is adjusted by the control system to achieve the engagement or separation of the dehydration shaft 3 and the drainage shaft 2, and finally achieve the control of different working conditions of the corresponding washing machine. Among them, the outer clutch sleeve 1003 can be fixed at three positions along the axial direction, and the inner clutch sleeve 1001 can be fixed at two positions along the axial direction. The inner clutch sleeve 1001 and the outer clutch sleeve 1003 cooperate with each other under the control of the clutch finger to form the following Fig. 9 In the three position structures shown in FIG. 1 , FIG. 2 , and FIG. 3 , the upper clutch sleeve 10 and the clutch wheel 5 are in the upper and lower positions under the action of the control system or the clutch finger, and different working conditions of the washing machine are realized according to the action of the increased clutch. Fig. 9 The a and b mentioned in the figure represent the tooth root horizontal line and the tooth top horizontal line of the second meshing tooth on the fixed sleeve; c and d represent the tooth top horizontal line and the tooth root horizontal line of the third meshing tooth of the movable sleeve.

[0045] like Fig. 9As shown, when the lower clutch device 10 is in the first position, the traction device does not work, and under the action of the external clutch pawl spring force, the lower clutch device 10 is in the upper state, and the inner clutch sleeve 1001 and the outer clutch sleeve 1003 are both in the uppermost position. At this time, the second meshing tooth at the lower end of the fixed sleeve is meshed with the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 1003; the first meshing tooth at the lower end of the clutch shaft 12 is meshed with the fifth meshing tooth A2 at the upper end of the inner clutch sleeve 1001; the third meshing tooth on the movable sleeve 17 is separated from the fourth meshing tooth A1 at the lower end of the inner clutch sleeve 1001; at the same time, the third meshing tooth on the movable sleeve 17 is separated from the sixth meshing tooth B1 of the outer clutch sleeve 1003.

[0046] Since the fixed sleeve is stationary, the second meshing teeth at the lower end of the fixed sleeve mesh with the seventh meshing teeth B2 at the upper end of the outer clutch sleeve 1003, and the outer clutch sleeve 1003 is fixed at this time; since the second spline at the lower end of the clutch shaft 12 meshes with the fourth spline D1 on the inner side wall of the outer clutch sleeve 1003, the clutch shaft 12 is fixed under the action of the outer clutch sleeve 1003. Since the first meshing teeth at the lower end of the clutch shaft 12 mesh with the fifth upper meshing teeth A2 at the upper end of the inner clutch sleeve 1001, the inner clutch sleeve 1001 is fixed at this time; since the first spline at the lower end of the intermediate shaft 13 meshes with the third spline C1 on the inner side wall of the inner clutch sleeve 1001, the intermediate shaft 13 is fixed under the action of the inner clutch sleeve 1001.

That is, at this time, the clutch shaft 12 and the intermediate shaft 13 are fixed by the fixed sleeve and remain relatively independent from the input shaft 11. The clutch shaft 12 is fixedly connected to the brake wheel 3, and finally the brake wheel 3 is braked, and the dehydration shaft 3 connected to the brake wheel 3 also remains stationary.

[0050] Since the first meshing teeth at the lower end of the clutch shaft 12 are separated from the fifth meshing teeth A2 at the upper end of the inner clutch sleeve 1001, the inner clutch sleeve 1001 is relatively independent from the outer clutch sleeve 1003. That is, the clutch shaft 12 and the intermediate shaft 13 remain relatively independent.

[0051] The movable sleeve is fixed to the input shaft 11. Since the third meshing teeth on the movable sleeve are meshed with the four meshing teeth A1 at the lower end of the inner clutch sleeve 1001, the inner clutch sleeve 1001 is fixed to the input shaft 11.

That is, at this time, the clutch shaft 12 is fixed by the fixed sleeve, the intermediate shaft 13 is fixed to the input shaft 11, and the clutch shaft 12 and the intermediate shaft 13 fixed together and the input shaft 11 are relatively independent. The intermediate shaft 13 is meshed with the input shaft 11 and rotates, and the clutch shaft 12 is fixed. This is the second position of the lower clutch device 10.

[0052] When the lower clutch device 10 is in position II and moves toward position III, the double-stroke traction device performs the second action, the clutch finger rotates the preset angle again, and the position of the inner clutch sleeve 1001 is consistent with the above-mentioned opposite-direction dual power output. The outer clutch sleeve 1003 moves down one position and is in the lower state.

[0053] At this time, the second meshing tooth at the lower end of the fixed sleeve is separated from the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 1003; the first meshing tooth at the lower end of the clutch shaft 12 is separated from the fifth upper meshing tooth A2 at the upper end of the inner clutch sleeve 1001; the third meshing tooth on the movable sleeve is meshed with the fourth meshing tooth A1 at the lower end of the inner clutch sleeve 1001; at the same time, the third meshing tooth on the movable sleeve is meshed with the sixth meshing tooth B1 of the outer clutch sleeve 1003.
