[0045] Further, such as Figure 2 to Figure 7 The figure shows a schematic diagram of the deceleration clutch and the clutch sleeve structure. The washing machine also includes a bearing support 9, in which a deceleration gear train and a brake assembly are installed. The brake assembly is installed inside the bearing support 9 through a bearing 10.

[0046] The reduction gear train includes an upper planetary gear and a lower planetary gear, thereby forming a double-set planetary reduction mechanism.

The upper planetary gear is movably mounted on the upper planetary carrier 7 connected to the impeller shaft 4, and an upper central gear 16 is provided on the top of the input shaft 1; the inner side of the upper planetary gear meshes with the upper central gear 16 on the top of the input shaft 1, and its outer side is separated from the internal gear 6, so as not to generate interaction. The lower planetary gear is movably mounted on the clutch shaft 3, that is, the clutch shaft 3 is the lower planetary carrier, and the lower central gear 15 is provided on the top of the intermediate shaft 2; the inner side of the lower planetary gear meshes with the lower central gear 15 on the top of the intermediate shaft, and its outer side meshes with the internal gear 6.

[0047] like Figure 3-Figure 9 As shown, a fixed sleeve 11 is fixedly installed at the lower end of the bearing support 9, and the fixed sleeve 11 is provided with a second meshing tooth B2', and the second meshing tooth B2' forms a slot. The lower ends of the input shaft 1, the intermediate shaft 2 and the clutch shaft 3 are all provided with spline teeth, and the spline teeth at the lower ends of the input shaft 1, the intermediate shaft 2 and the clutch shaft 3 are input shaft spline, first spline C1', and second spline D1' respectively. The lower end of the clutch shaft 3 is provided with a first meshing tooth A2' on the lower side of the first spline C1'. A movable sleeve 12 and a pulley 13 are also mounted on the input shaft spline at the lower end of the input shaft 1, and the pulley 13 is fixed to the input shaft 1 by a nut 14. The movable sleeve 12 is provided with a third meshing tooth A1'.

[0048] The intermediate shaft 2 and the clutch shaft 3 are provided with a clutch sleeve assembly 8, which can slide in the axial direction, so that the clutch sleeve assembly 8 is engaged or separated with the input shaft 1, the intermediate shaft 2 and the clutch shaft 3, so as to control the relative engagement relationship between the three shafts of the input shaft 1, the intermediate shaft 2 and the clutch shaft 3. The clutch sleeve assembly 8 includes an inner clutch sleeve 81 and an outer clutch sleeve 83 separated from each other, the inner clutch sleeve 81 is sleeved in the outer clutch sleeve 83, the inner sleeve can rotate freely in the circumferential direction, the inner side of the outer clutch sleeve 83 is provided with a first step surface in the circumferential direction, the outer side of the inner clutch sleeve 81 is provided with a second step surface in the circumferential direction, the second step surface is relatively independent of the first step surface, the second step surface on the inner clutch sleeve 81 is located on the first step surface of the outer clutch sleeve 83, so that the inner clutch sleeve 81 and the outer clutch sleeve 83 are engaged in the axial direction.

[0049] The inner side wall of the inner clutch sleeve 81 is provided with a third spline C1, the lower end is provided with a fourth meshing tooth A1, and the upper end is provided with a fifth meshing tooth A2. The inner side wall of the outer clutch sleeve 83 is provided with a fourth spline D1, the lower end is provided with a sixth meshing tooth B1, and the upper end is provided with a seventh meshing tooth B2. The inner clutch sleeve 81 and the outer clutch sleeve 83 are respectively covered with a small compression spring 82 and a large compression spring 84, and the small compression spring 82 and the large compression spring 84 are movably installed on the inner clutch sleeve 81 and the outer clutch sleeve 83. The outer clutch sleeve 83 can slide axially.

[0050] The meshing relationship of various types of teeth on the intermediate shaft 2, the clutch shaft 3, the outer clutch sleeve 83, and the inner clutch sleeve 81 is as follows:

[0051] The first spline C1' at the lower end of the intermediate shaft 2 is always meshed with the third spline C1 on the inner wall of the inner clutch sleeve 81;

[0052] The second spline D1' at the lower end of the clutch shaft 3 is always meshed with the fourth spline D1 on the inner wall of the outer clutch sleeve 83;

[0053] The second meshing tooth B2' at the lower end of the fixed sleeve 11 is meshed or disengaged with the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83;

[0054] The first meshing tooth A2' at the lower end of the clutch shaft 3 is meshed or disengaged with the fifth upper meshing tooth A2 at the upper end of the inner clutch sleeve 81;

[0055] The third meshing teeth A1 ′ on the movable sleeve 12 mesh with or disengage the fourth meshing teeth A1 at the lower end of the inner clutch sleeve 81 ; at the same time, the third meshing teeth A1 ′ on the movable sleeve 12 can also mesh with or disengage the sixth meshing teeth B1 of the outer clutch sleeve 83 .

[0056] like Figure 1 As shown, the washing machine is provided with a clutch finger 24, and the clutch finger 24 is connected to a double-stroke tractor. Under the action of the external clutch finger, the clutch sleeve assembly 8 can be fixed in three positions, namely, the upper position, the middle position, and the lower position, from the top to the bottom of the washing machine. Under the action of the tractor, the clutch finger adjusts the position of the clutch sleeve assembly 8, so that the outer clutch sleeve 83 and the inner clutch sleeve 81 are respectively in different positions, thereby controlling the relationship between the three axes of the input shaft 1, the intermediate shaft 2, and the clutch shaft 3, and finally realizing the control of the corresponding different working conditions of the washing machine. Among them, the outer clutch sleeve 83 can be fixed in three positions along the axial direction, and the inner clutch sleeve 81 can be fixed in two positions along the axial direction. The inner clutch sleeve 81 and the outer clutch sleeve 83 cooperate with each other under the control of the clutch finger to realize different working conditions of the washing machine.

[0057] like Figure 10-11When the washing machine is in normal washing condition, the traction device does not work, and under the action of the external clutch claw spring force, the clutch sleeve assembly 8 is in the upper state, and the clutch inner sleeve 81 and the outer clutch sleeve 83 are both in the uppermost position.

[0058] When the clutch sleeve assembly 8 is in the upper state, the second meshing tooth B2' at the lower end of the fixed sleeve 11 meshes with the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83; the first meshing tooth A2' at the lower end of the clutch shaft 3 meshes with the fifth meshing tooth A2 at the upper end of the inner clutch sleeve 81; the third meshing tooth A1' on the movable sleeve 12 is separated from the fourth meshing tooth A1 at the lower end of the inner clutch sleeve 81; at the same time, the third meshing tooth A1' on the movable sleeve 12 is separated from the sixth meshing tooth B1 of the outer clutch sleeve 83.

[0059] Since the fixed sleeve 11 is fixed, the second meshing teeth B2' at the lower end of the fixed sleeve 11 mesh with the seventh meshing teeth B2 at the upper end of the outer clutch sleeve 83, and the outer clutch sleeve 83 is fixed at this time; since the second spline D1' at the lower end of the clutch shaft 3 meshes with the fourth spline D1 on the inner side wall of the outer clutch sleeve 83, the clutch shaft 3 is fixed under the action of the outer clutch sleeve 83. Since the first meshing teeth A2' at the lower end of the clutch shaft 3 mesh with the fifth upper meshing teeth A2 at the upper end of the inner clutch sleeve 81, the inner clutch sleeve 81 is fixed at this time; since the first spline C1' at the lower end of the intermediate shaft 2 meshes with the third spline C1 on the inner side wall of the inner clutch sleeve 81, the intermediate shaft 2 is fixed under the action of the inner clutch sleeve 81. At the same time, since the third meshing tooth A1' on the movable sleeve 12 is separated from the four meshing teeth A1 at the lower end of the inner clutch sleeve 81; and the third meshing tooth A1' on the movable sleeve 12 is separated from the sixth meshing tooth B1 of the outer clutch sleeve 83, the inner clutch sleeve 81 and the outer clutch sleeve 83 remain relatively independent from the input shaft 1. That is, at this time, the clutch shaft 3 and the intermediate shaft 2 are fixed by the fixed sleeve 11 and remain relatively independent from the input shaft 1. The meshing relationship between the intermediate shaft 2 and the lower planetary gear causes the lower planetary gear to be braked, and finally the inner gear 6 is braked, and the dehydration shaft 5 connected to the inner gear 6 also remains stationary. When the input shaft 1 rotates, the input gear at the top of the input shaft 1 meshes with the upper planetary gear, thereby driving the upper planetary carrier 7 to rotate in the same direction as the input shaft 1, and finally the impeller shaft 4 rotates under the power of the input shaft 1. At this time, only the impeller in the washing machine is placed under the action of the input shaft 1, and it is a single power output.

[0060] like Figure 12-13 When the washing machine is in dual-power washing mode, the traction device executes the first stroke, the clutch finger rotates through a preset angle, and the inner clutch sleeve 81 and the outer clutch sleeve 83 of the clutch sleeve assembly 8 move downward by one stroke under the action of the small compression spring 82 and the large compression spring 84 respectively. At this time, the clutch sleeve assembly 8 is in a neutral state.

[0061] At this time, the second meshing tooth B2' at the lower end of the fixed sleeve 11 meshes with the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83; the first meshing tooth A2' at the lower end of the clutch shaft 3 is separated from the fifth upper meshing tooth A2 at the upper end of the inner clutch sleeve 81; the third meshing tooth A1' on the movable sleeve 12 meshes with the fourth meshing tooth A1 at the lower end of the inner clutch sleeve 81; the third meshing tooth A1' on the movable sleeve 12 is separated from the sixth meshing tooth B1 of the outer clutch sleeve 83.

[0062] The fixed sleeve 11 is fixed, and the outer clutch sleeve 83 is fixed at this time because the second meshing tooth B2' at the lower end of the fixed sleeve 11 meshes with the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83; the clutch shaft 3 is fixed under the action of the outer clutch sleeve 83 because the second spline D1' at the lower end of the clutch shaft 3 meshes with the fourth spline D1 on the inner wall of the outer clutch sleeve 83. The movable sleeve 12 is fixed to the input shaft 1, and the clutch shaft 3 and the input shaft 1 remain relatively independent because the third meshing tooth A1' on the movable sleeve 12 is separated from the sixth meshing tooth B1 of the outer clutch sleeve 83.

[0063] Since the first meshing tooth A2' at the lower end of the clutch shaft 3 is separated from the fifth meshing tooth A2 at the upper end of the inner clutch sleeve 81, the inner clutch sleeve 81 is relatively independent from the outer clutch sleeve 83. That is, the clutch shaft 3 and the intermediate shaft 2 remain relatively independent.

[0064] The movable sleeve 12 is fixed to the input shaft 1. Since the third meshing teeth A1' on the movable sleeve 12 mesh with the four meshing teeth A1 on the lower end of the inner clutch sleeve 81, the inner clutch sleeve 81 is fixed to the input shaft. Since the first spline C1' on the lower end of the intermediate shaft 2 meshes with the third spline C1 on the inner wall of the inner clutch sleeve 81, the intermediate shaft 2 is fixed to the input shaft 1 under the action of the inner clutch sleeve 81. That is, at this time, the clutch shaft 3 is fixed by the fixed sleeve 11, the intermediate shaft 2 and the input shaft 1 are fixed together, the clutch shaft 3 is independent of the intermediate shaft 2 and the input shaft 1 fixed together, the intermediate shaft 2 meshes with the input shaft 1 to rotate, and the clutch shaft 3 is fixed.

[0065] The lower central gear 15 at the top of the intermediate shaft 2 meshes with the lower planetary gears, thereby driving the internal gear 6 to rotate in the opposite direction to the intermediate shaft 2. Since the internal gear 6 is connected to the dehydration shaft 5, driven by the internal gear 6, the dehydration shaft 5 rotates in the opposite direction to the intermediate shaft 2, that is, the dehydration shaft 5 connected to the internal gear 6 rotates in the opposite direction to the input shaft 1 under the action of the reduction gear train. The upper central gear 16 at the top of the input shaft 1 meshes with the upper planetary gears, driving the upper planetary carrier 7 and the input shaft 1 to rotate in the same direction; since the pulsator shaft 4 is connected to the upper planetary carrier 7, driven by the rotation of the upper planetary carrier 7, the pulsator shaft 4 rotates in the same direction under the power of the input shaft 1, that is, the pulsator shaft 4 and the dehydration shaft 5 rotate in different directions, and the pulsator and the inner tub connected to them respectively rotate in the opposite direction. At this time, the washing condition is a double power output in different directions.

[0066] like Figures 14-15 As shown, when the washing machine is in the dehydration state or the centrifugal washing state, 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 81 remains consistent with the output in the above-mentioned dual-power washing mode. The outer clutch sleeve 83 moves down one position and is in the lower position.

[0067] At this time, the second meshing tooth B2' at the lower end of the fixed sleeve 11 is separated from the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83; the first meshing tooth A2' at the lower end of the clutch shaft 3 is separated from the fifth upper meshing tooth A2 at the upper end of the inner clutch sleeve 81; the third meshing tooth A1' on the movable sleeve 12 is meshed with the fourth meshing tooth A1 at the lower end of the inner clutch sleeve 81; at the same time, the third meshing tooth A1' on the movable sleeve 12 is meshed with the sixth meshing tooth B1 of the outer clutch sleeve 83.

[0068] Since the second meshing tooth B2' at the lower end of the fixed sleeve 11 is separated from the seventh meshing tooth B2 at the upper end of the outer clutch sleeve 83, the outer clutch sleeve 83 is relatively independent from the fixed sleeve 11, and the outer clutch sleeve 83 is not restricted by the fixed sleeve 11;

[0069] Since the first meshing tooth A2 ′ at the lower end of the clutch shaft 3 is separated from the fifth upper meshing tooth A2 at the upper end of the inner clutch sleeve 81 , the inner clutch sleeve 81 and the outer clutch sleeve 83 are relatively independent at this time.

[0070] The movable sleeve 12 is fixed to the input shaft 1 . Since the third meshing teeth A1 ′ on the movable sleeve 12 mesh with the sixth meshing teeth B1 of the outer clutch sleeve 83 , the outer clutch sleeve 83 is fixed to the input shaft 1 .

[0071] Since the second spline D1' at the lower end of the clutch shaft 3 is meshed with the fourth spline D1 on the inner wall of the outer clutch sleeve 83, the outer clutch sleeve 83 is fixed to the clutch shaft 3. That is, the clutch shaft 3 is fixed to the input shaft 1 through the outer clutch sleeve 83.

[0072] The movable sleeve 12 is fixed together with the input shaft 1. Since the third meshing tooth A1' on the movable sleeve 12 is meshed with the four meshing teeth A1 at the lower end of the inner clutch sleeve 81, the inner clutch sleeve 81 is fixed together with the input shaft 1. Since the first spline C1' at the lower end of the intermediate shaft 2 is meshed with the third spline C1 on the inner side wall of the inner clutch sleeve 81, under the action of the inner clutch sleeve 81, the intermediate shaft 2 is fixed together with the input shaft 1.

[0073] That is, at this time, the clutch shaft 3, the intermediate shaft 2, and the input shaft 1 are fixed together. At this time, the clutch shaft 3, the intermediate shaft 2, and the input shaft 1 rotate together, and the reduction gear train is engaged with the input shaft 1. When the input shaft 1 rotates, the dehydration shaft 5 connected to the internal gear 6 and the pulsator shaft 4 rotate in the same direction under the simultaneous action of the three shafts at the input end, which is the same speed output in the dehydration state.

[0074] In summary, the three basic working conditions of the washing machine of the present invention are as follows:

[0075] When the intermediate shaft 2 and the clutch shaft 3 are fixed at the same time, when the input shaft 1 rotates, the lower central gear 15 and the lower planetary carrier are fixed, so the internal gear 6 does not rotate, the dehydration shaft 5 does not rotate, and the impeller shaft 4 rotates, so that the impeller rotates alone.

[0076] When the clutch shaft 3 is fixed, the intermediate shaft 2 and the input shaft 1 are connected and rotated together, the lower central gear 15 rotates and the lower planetary carrier is fixed, so the internal gear 6 rotates, and at the same time the upper planetary gear system rotates the impeller shaft 4, so that the impeller and the washing tub rotate in opposite directions at the same time.

[0077] When the clutch shaft 3, the intermediate shaft 2 and the input shaft 1 rotate together, the two sets of gear trains and the brake wheel are integrated to achieve dehydration rotation.

[0078] This embodiment describes a clutch mechanism that can achieve three working conditions. Other commonly used clutch mechanisms can also be used to achieve control of the input shaft, the intermediate shaft and the clutch shaft, and ultimately achieve control of the working conditions.

[0079] The three working states of the washing machine in the present invention can be switched sequentially as in the embodiment, or can be set to be controlled separately, so as to switch between the three states as needed.

[0080] The product of the present invention provides a switching component on the deceleration clutch, and under the cooperation of the clutch component, the power output can be switched to obtain a multifunctional washing machine, which can reduce cost investment and space occupation.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
