The deceleration clutch device comprises a clutch housing, an outer rotor motor consisting of a rotor and a stator, and an input shaft fixedly connected to the rotor and mounted on the housing. An input sleeve is disposed on the outer side of the input shaft and is rotatable about its axis. A clutch sleeve is mounted on the input sleeve and slides up and down. The clutch sleeve is connected to the traction motor via a control mechanism. When the clutch sleeve is in a first position, the input sleeve engages with the housing via the clutch sleeve. When the clutch sleeve is in a second position, the input sleeve engages with the rotor via the clutch sleeve. A control mechanism consisting of a connecting arm, a shift fork, and a clutch spring transmits the controllable traction force of the traction motor to the clutch sleeve, enabling the clutch sleeve to slide up and down. However, this solution requires the installation of a lower housing and control mechanism at the bottom of the inner tub.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] like Figures 1 to 7 As shown, the washing machine 8 of the present invention includes an inner barrel 81, an outer barrel 82, a washing shaft 1 and a dehydration shaft 2 sleeved on the washing shaft 1, one end of the dehydration shaft 2 is connected to the inner barrel 81, and further includes:

[0045] A clutch assembly is slidably mounted on the washing shaft 1 between the inner tub 81 and the outer tub 82;

[0046] The driving module 5 is detachably connected to the clutch assembly and is used to drive the clutch assembly to connect to / disconnect from the dehydration shaft 2, so that the dehydration shaft 2 and the washing shaft 1 rotate together / independently.

[0047] The washing shaft 1 is arranged in the inner tub 81 and the outer tub 82. The washing machine 8 of the present invention is a drum washing machine or a pulsator washing machine. This embodiment is specifically described by taking a pulsator washing machine as an example.

[0048] The present invention arranges the clutch assembly between the inner drum 81 and the outer drum 82, and drives the clutch assembly to connect / disconnect with the dehydration shaft 2 through the driving module 5, so that the washing shaft 1 and the dehydration shaft 2 can rotate integrally or non-integratedly, thereby controlling the washing machine 8 to dehydrate or wash. The clutch assembly has a simple structure and is arranged between the inner and outer drums 82, occupying a small space, saving the internal space of the washing machine and reducing the size of the washing machine. Under the condition that the size of the washing machine remains unchanged, the washing space of the washing machine can be increased, thereby realizing the washing capacity expansion of the washing machine.

[0049] Specifically, the drive module 5 is used to drive the clutch assembly to engage or disengage with the dehydration shaft 2, causing the dehydration shaft 2 and the washing shaft 1 to rotate together or independently. When the clutch assembly is engaged with the dehydration shaft 2, the dehydration shaft 2 and the washing shaft 1 rotate together; when the clutch assembly is disengaged from the dehydration shaft 2, the dehydration shaft 2 does not rotate with the rotation of the washing shaft 1, and the dehydration shaft 2 rotates independently instead of being rotated together.

[0050] There is a distance between the other end of the dehydration shaft 2 and the bottom of the outer barrel 82, which at least constitutes a range of motion for the clutch assembly to slide away from the dehydration shaft 2. The clutch assembly is sleeved on the washing shaft 1 and is located below the dehydration shaft 2 so as to slide up and down.

[0051] like Figures 3 to 7 As shown, the clutch assembly includes a clutch ring 3, and the clutch ring 3 has a first connecting member for being integrally rotatably connected to the washing shaft 1; and a second connecting member for being meshedly connected to the dehydration shaft 2.

[0052] In a preferred embodiment, the first connecting member is a spline provided on the inner circumferential wall of the clutch ring 3, the second connecting member is a spline provided on the outer circumferential wall of the clutch ring 3, and the inner circumferential wall of the other end of the dehydration shaft 2 is provided with a spline that matches and engages with the second connecting member. Preferably, the clutch ring 3 is a circular ring that rotates integrally with the washing shaft 1.

[0053] The spline on the outer wall of the clutch ring 3 has a guiding bevel (not shown in the figure) at one end close to the dehydration shaft 2, and / or the spline on the inner wall of the dehydration shaft 2 has a guiding bevel at one end close to the clutch ring 3, which is used to guide the clutch ring 3 into the dehydration shaft 2.

[0054] Another preferred solution (not shown in the figure) is that the clutch ring 3 is a circular ring, the first connecting member is a spline provided on the inner wall of the clutch ring 3, and the second connecting member is a clutch tooth provided on the end face of the clutch ring 3 facing the dehydration shaft 2, and the end face of the other end of the dehydration shaft 2 is provided with end face teeth that match and engage with the second connecting member.

[0055] Furthermore, a flange 22 is provided at the upper end of the dehydration shaft 2, and the flange 22 is connected to the inner barrel 81. The flange 22 has a connecting hole 221 arranged along the axial direction.

[0056] Specifically, the dehydration shaft 2 is connected to the outer side of the bottom of the inner barrel 81, and the flange 22 of the dehydration shaft 2 is connected to the outer side of the bottom of the inner barrel 81. The outer side of the bottom of the inner barrel 81 is also provided with a hole, and the connecting hole 221 of the flange 22 and the hole of the inner barrel 81 are connected by bolts or screws.

[0057] The washing machine 8 further includes a pulsator 83 and a variable frequency motor 84. The variable frequency motor 84 is disposed on the outer tub 82. One end of the washing shaft 1 is connected to the pulsator 83, and the other end is in transmission connection with the variable frequency motor 84. The variable frequency motor 84 is disposed on the outer side of the bottom of the outer tub 82. The washing shaft 1 is inserted into the outer tub 82 and in transmission connection with the variable frequency motor 84.

[0058] The washing machine 8 of the present invention is not provided with a deceleration device. By arranging a frequency conversion motor 84 outside the outer barrel 82 of the washing machine, the frequency conversion motor 84 controls and adjusts the rotation speed of the impeller 83 and / or the inner barrel 81 for washing, which simplifies the internal structure of the washing machine, saves space inside the washing machine, reduces the height of the washing machine, and is conducive to the capacity expansion of the washing machine. The washing machine of the present invention has a simple structure, is easy to install, and reduces costs.

[0059] The clutch assembly further comprises a bracket 4, which is slidably sleeved on the washing shaft 1 and is located between the clutch ring 3 and the outer barrel 82. The upper end of the bracket 4 can abut against the lower end surface of the clutch ring 3.

[0060] Preferably, the washing shaft 1 includes a first shaft segment 11, a second shaft segment 12 and a third shaft segment 13 connected in sequence from top to bottom, the diameter of the second shaft segment 12 is larger than the diameters of the first shaft segment 11 and the third shaft segment 13, and the outer peripheral wall of the upper end of the second shaft segment 12 is provided with a spline that can engage with the clutch ring 3. When the bracket 4 is pressed down, it is sleeved on the smooth outer peripheral wall of the lower end of the second shaft segment 12.

[0061] The dehydration shaft 2 is sleeved on the washing shaft 1 and includes a coaxially arranged stepped hole, which includes a first hole segment 23, a second hole segment 24, and a third hole segment 25 connected in sequence at the upper and lower ends. The aperture of the second hole segment 24 is smaller than that of the first hole segment 23 and the third hole segment 25. The first hole segment 23, the second hole segment 24, and the third hole segment 25 are straight through holes.

[0062] The inner wall of the dehydration shaft 2 is provided with ribs 21 along the circumferential direction. The dehydration shaft 2 is located above the connection between the first shaft section 11 and the second shaft section 12 through the ribs 21, which can prevent the washing shaft 1 from passing through the dehydration shaft 2.

[0063] One end of the dehydration shaft 2, having the first hole section 23, is connected to the inner barrel 81. A rib 21 is provided on the inner wall of the lower end of the first hole section 23. The third hole section 25 is provided with a spline that matches the clutch ring 3. Under the action of an external force, the clutch ring 3 enters the third hole section 25 at the lower end of the dehydration shaft 2 and connects with the spline in the third hole section 25.

[0064] The washing machine 8 also includes a pulsator 83 and a variable frequency motor 84. Specifically, the first shaft section 11 is connected to the pulsator 83, and the third shaft section 13 is transmission-connected to the variable frequency motor 84. The washing shaft 1 drives the pulsator 83 to rotate, and the speed of the washing shaft 1 is controlled by the variable frequency motor 84. The dehydration shaft 2 can rotate integrally with the washing shaft 1.

[0065] A sealing structure 7 is provided at the connection between the upper end of the dehydration shaft 2 and the washing shaft 1 , which can cooperate with the inner barrel 81 to prevent water in the barrel from flowing out of the inner barrel 81 .

[0066] The sealing structure 7 is sleeved on the washing shaft 1 and installed above the rib 21. Preferably, the rib 21 is a circular rib.

[0067] The center of the bracket 4 has a through hole 42 for the washing shaft 1 to pass through. The two ends of the bracket 4 extend from the through hole 42 toward the periphery. The diameter of the through hole 42 is smaller than the outer diameter of the clutch ring 3. Preferably, the bracket 4 is a sheet metal member having a length.

[0068] Preferably, the bracket 4 is a centrally symmetrical structure. Preferably, the bracket 4 is a support plate or a support rod. The bracket 4 is a rectangular plate or a long rod or a special-shaped plate. The length of the bracket 4 matches the diameter of the outer barrel 82.

[0069] The bracket 4 is provided with connecting portions at both ends in the longitudinal direction for detachable connection with the driving module 5. Preferably, the connecting portion is a notch 41 provided on one side of the bracket 4 in the width direction, and the notches 41 near both ends of the bracket 4 are oriented in the same circumferential direction.

[0070] Preferably, the notches 41 near both ends of the bracket 4 are arranged symmetrically with respect to the through hole 42 .

[0071] A clutch spring 6 is provided between the bracket 4 and the bottom of the outer barrel 82 . The clutch spring 6 is sleeved on the washing shaft 1 . Both ends of the clutch spring 6 are in contact with the bracket 4 and the outer barrel 82 , respectively.

[0072] When the washing machine 8 is dehydrating, the clutch spring 6 presses the bracket 4 upward, so that the clutch ring 3 is engaged with the dehydration shaft 2.

[0073] The driving module 5 is installed on the outside of the bottom of the outer barrel 82. The driving module 5 includes a telescopic rod 51 (see Figure 2 ) and drive member 53 (see Figure 2), one end of the telescopic rod 51 is connected to the driving component 53 on the outside of the bottom of the outer barrel 82, and the other end is telescopically arranged in the outer barrel 82 and is detachably connected to the notch 41. The end of the other end of the telescopic rod 51 is provided with a stop 52 for preventing the telescopic rod 51 from detaching from the notch 41 in the telescopic direction.

[0074] The location of the telescopic rod 51 matches the notch 41, and the diameter of the telescopic rod 51 is smaller than the diameter of the notch 41. Preferably, the driving module 5 includes two sets of driving components 53 and telescopic rods 51 that are connected.

[0075] The distance between the telescopic rod 51 and the washing axis 1 is the same as the distance between the notch 41 and the washing axis 1. The driving component 53 is disposed on the outside of the bottom of the outer tub 82, opposite to the two ends of the bracket 4. The location of the telescopic rod 51 corresponds to the notch 41.

[0076] When the bracket 4 rotates in a certain direction (such as clockwise), the notch 41 clamps the telescopic rod 51; when the bracket 4 rotates in the opposite direction (such as counterclockwise), the notch 41 rotates away from the telescopic rod 51, and the telescopic rod 51 is separated from the bracket 4.

[0077] The stopper 52 engages the upper end of the bracket 4 and is used to drive the bracket 4 downward when the telescopic rod 51 moves downward, causing the clutch ring 3 to fall and disengage from the dehydration shaft 2. Preferably, the stopper 52 is a circular disk. The telescopic rod 51 is positioned along the path of the notch 41 of the bracket 4 as it rotates around the through hole 42.

[0078] The driving module 5 has two working states:

[0079] In the first working state, the telescopic rod 51 of the driving module 5 drives the bracket 4 to move downward, pressing the clutch spring 6 downward to disengage the clutch assembly from the dehydration shaft 2;

[0080] The second working state is that the telescopic rod 51 of the driving module 5 moves upward, and the clutch assembly is bounced up by the clutch spring 6 and engages with the dehydration shaft 2.

[0081] Specifically, the bottom wall of the baffle 52 abuts against the top wall of the bracket 4. When the driving component 53 drives the telescopic rod 51 to move downward, the baffle 52 drives the bracket 4 to move downward, away from the clutch ring 3. The clutch ring 3 falls under the action of gravity and separates from the dehydration shaft 2, so that the washing shaft 1 and the dehydration shaft 2 do not rotate as a whole.

[0082] When the driving structure drives the telescopic rod 51 to move upward, the bracket 4 is no longer subjected to downward force, and the clutch spring 6 recovers its deformation, providing an upward force to the bracket 4, driving the clutch ring 3 to move upward, so that the clutch ring 3 engages with the dehydration shaft 2, and the washing shaft 1 and the dehydration shaft 2 rotate as a whole.

[0083] In the washing machine 8 described in the present invention, the driving module 5 does not need to be set at the bottom of the inner barrel 81 of the washing machine, but can be set on the outside of the outer barrel 82 of the washing machine, saving the internal space between the inner barrel and the outer barrel of the washing machine, making the volume of the washing machine smaller, and increasing the washing space of the inner barrel, thereby realizing the washing capacity expansion of the washing machine.

[0084] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above-mentioned embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
