Description

Technical Field

[0001] This invention belongs to the field of washing machines, specifically, it relates to a dual traction device with dual-stroke operation and single-stroke operation, a reduction clutch, and a washing machine. Background Technology

[0002] The washing machine's dual-power reduction clutch enables the spin-dry shaft and the inner tub connected to it to rotate in the opposite direction to the pulsator shaft. In practical applications, the pulsator and the inner tub rotate simultaneously, but in opposite directions, creating bidirectional power.

[0003] During the washing cycle, the conventional dual-power reduction clutch brake wheel relies on the brake band to hold the machine in place when braking clockwise, and on the one-way bearing to lock it in place when braking counterclockwise. The motor drives the spin-dry shaft and the impeller shaft to rotate simultaneously in both directions through the dual planetary gear reduction mechanism, generating bidirectional counter-current water flow. However, when the motor power is too high or the direction is changed rapidly, the brake band cannot hold the brake wheel tightly, and the brake wheel rotates clockwise at a large angle. This results in a weak or even no counterclockwise rotation angle for the spin-dry shaft and the inner spin-dry tub connected to it, thus losing the function and effect of the dual-power reducer and affecting the user experience.

[0004] Chinese patent application number CN202010699552.1 discloses a deceleration clutch device for a washing machine and a washing machine, but it cannot achieve the washing effect of locking the brake wheel when the inner tub and the impeller rotate in opposite directions at the same time.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dual-stroke traction device, a deceleration clutch and a washing machine that cooperates with a single stroke, which can ensure that the brake wheel does not rotate during washing and improve the washing effect.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A dual-traction device for a washing machine, combining a dual-stroke and a single-stroke mechanism, includes a first traction device and a second traction device.

[0009] The first traction device is a single-stroke traction device that controls the braking mechanism of the washing machine.

[0010] The second traction device is a double-stroke traction device that controls the movement of the washing machine's deceleration clutch fork.

[0011] Furthermore, the first and second traction devices are installed at the bottom of the outer tub of the washing machine, and the installation positions of the two traction devices are symmetrical or nearly symmetrical.

[0012] A washing machine deceleration clutch has a second bidirectional rotary bearing at the first connection port of the brake wheel, the brake wheel is connected to the outer ring of the second bidirectional rotary bearing, and the spin-drying shaft is connected to the inner ring of the second bidirectional rotary bearing.

[0013] Furthermore, a first bidirectional rotary bearing is provided between the input shaft sleeve and the lower end inner wall of the housing of the reduction clutch.

[0014] Furthermore, it includes a clutch sleeve with two working positions. In the two working positions, it engages with the washing gear and the torque shaft sleeve respectively. When the clutch sleeve engages with the washing gear, the spin-dry shaft and the impeller shaft rotate in opposite directions simultaneously, and the brake wheel is locked in place. When the clutch sleeve engages with the torque shaft sleeve, the spin-dry shaft and the impeller shaft rotate in the same direction.

[0015] A washing machine, including the dual-stroke cooperating single-stroke dual traction device as described in any one of the above, and the washing machine reduction clutch as described in any one of the above.

[0016] Furthermore, during the washing cycle, the brake wheel of the washing machine's deceleration clutch is locked and does not rotate.

[0017] Furthermore, before entering the washing mode, the brake arm of the brake device is opened by the first traction device, and then the shift fork is driven by the second traction device to move the clutch sleeve to engage with the washing gear and lock the input shaft sleeve, thereby locking the brake wheel.

[0018] Furthermore, before entering the dehydration state, the brake arm of the brake device is opened by the first traction device, and then the shift fork is reset by the second traction device. Under the elastic force of the clutch pressure spring, the clutch sleeve engages with the torque shaft sleeve.

[0019] Furthermore, the second actuator does not reset when the washing machine is powered off.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0021] This invention relates to a dual-stroke traction device, a reduction clutch, and a washing machine that works in conjunction with a single-stroke traction device. Through this dual-stroke traction device and a suitable reduction clutch, the brake wheel is locked and does not rotate during the washing process. The inner tub and pulsator of the washing machine can rotate simultaneously in both directions, generating bidirectional counter-current water flow. Even when the pulsator is large, the motor power is excessive, or there is a rapid reversal, the inner tub can still rotate well to generate a strong counter-current water flow, thereby improving the washing machine's cleaning effect, reducing abnormal noise from the brake wheel, and extending the lifespan of the braking system and other related components.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] To address the problem that in existing conventional dual-power reduction clutches, when the motor power is too high or the direction changes rapidly during the washing process, the brake band cannot effectively engage the brake wheel, causing the brake wheel to rotate as well. This results in a weak reverse rotation angle of the spin-dry shaft and the inner spin-dry tub connected to it, or even an inability to rotate counterclockwise. This invention proposes a dual-traction device for a washing machine with dual strokes and a single stroke, a washing machine reduction clutch, and a washing machine.

[0037] Example 1

[0038] In this embodiment, the washing machine uses a dual-stroke actuator in conjunction with a single-stroke actuator, wherein the first actuator 23 is a single-stroke actuator and the second actuator 24 is a dual-stroke actuator. When the two actuators are installed at the bottom of the outer tub of the washing machine, the installation positions of the first actuator 23 and the second actuator 24 are symmetrical or nearly symmetrical.

[0039] The first traction device 23 is connected to the brake arm 7 of the washing machine via a pull rope, controlling the washing machine's braking device. The braking device includes a brake arm and a brake band. The first traction device 23 pulls the brake arm via the pull rope, which in turn pulls the brake band and engages the brake wheel. When the washing machine needs to stop rotating, the first traction device 23 is activated, pulling the brake arm to engage the brake band and engage the brake wheel, thus stopping its rotation.

[0040] The second traction device 24 drives the shift fork assembly 6, thereby controlling the washing machine's deceleration clutch to lock the brake wheel during the washing program and unlock the brake wheel to put it in an active state during the spin-drying program.

[0041] Example 2

[0042] The present invention also provides a washing machine deceleration clutch, which includes a deceleration mechanism, a clutch mechanism and a locking mechanism.

[0043] The reduction mechanism includes a brake wheel 19 that can rotate in both directions, as well as an input shaft 1, a dehydration shaft 9, an input shaft sleeve 3, and a double planetary gear reduction mechanism. The input shaft 1 is coaxially installed inside the input shaft sleeve 3.

[0044] The clutch mechanism includes a clutch sleeve 16 that is sleeved on the input shaft sleeve 3 and can reciprocate along its axial direction.

[0045] The locking mechanism is used to lock the input shaft sleeve 3 and thus lock the brake wheel 19.

[0046] The locking mechanism includes a washing gear 12 fixedly sleeved outside the input shaft sleeve 3, such as... Figure 4 As shown, the washing gear 12 and the input shaft sleeve 3 are coaxially arranged, but they do not contact each other. The washing gear 12 is fixed to the housing of the reduction clutch. To achieve the fixed arrangement of the washing gear 12, the reduction clutch in this embodiment also includes a housing with an internal cavity. The housing includes an upper end shell 11 and a lower end shell 13, which are connected to form the internal cavity. The brake wheel 19 is disposed in the internal cavity of the housing. The housing has a housing inlet for the input shaft sleeve 3 to pass through. The washing gear 12 is fixed to the housing and located outside the inlet of the lower end shell 13.

[0047] The input shaft sleeve 3 has axially extending external teeth on its outer circumference, such as... Figure 6 As shown, the inner ring of the clutch sleeve 16 is provided with internal teeth extending along the axial direction, and the external teeth of the input shaft sleeve 3 mesh with the internal teeth of the clutch sleeve 16.

[0048] like Figure 4 As shown, since the clutch sleeve 16 and the washing gear 12 are coaxially sleeved outside the input shaft sleeve 3 and arranged vertically along the axial direction of the input shaft sleeve 3, with the washing gear 12 on top and the clutch sleeve 16 on the bottom, assuming the washing machine's reduction clutch is installed on the washing machine, the clutch sleeve 16 is positioned above the washing machine. Figure 4 , 5As shown in Figure 6, the washing gear 12 includes an annular body. A washing engagement tooth is provided at one end of the annular body near the clutch bushing 16, and an upper engagement tooth is provided at one end of the clutch bushing 16 near the washing gear 12. When the upper engagement tooth of the clutch bushing 16 engages with the washing engagement tooth of the washing gear 12, the washing gear 12 is fixed to the housing of the reduction clutch and will not rotate. Meanwhile, the inner teeth of the clutch bushing 16 engage with the outer teeth of the input bushing 3, thereby locking the input bushing 3. Since the input bushing 3 is fixedly connected to the brake wheel 19, the brake wheel 19 is also braked at the same time.

[0049] When the clutch sleeve 16 moves along the axial direction of the input shaft sleeve 3, when the clutch sleeve 16 approaches the washing gear 12, the two come into contact and engage through the meshing teeth; when the clutch sleeve 16 moves away from the washing gear 12, the two separate and disengage.

[0050] During the washing process, the deceleration clutch drives the impeller shaft and the spin-drying shaft to rotate in opposite directions simultaneously through its internal double planetary gear reduction mechanism. The input shaft sleeve 3 is locked by the locking mechanism, and the brake wheel 19 is also locked to prevent the brake wheel from rotating during the washing process. The specific application effect is as follows: during the washing process, the impeller connected to the impeller shaft rotates, the inner tub connected to the spin-drying shaft rotates, and the impeller and the inner tub rotate in opposite directions at the same time, while the brake wheel does not rotate.

[0051] The brake wheel 19 has a first connection port and a second connection port at both ends. A receiving cavity is formed inside the brake wheel 19 between the first connection port and the second connection port, and a double planetary gear reduction mechanism is installed inside the receiving cavity. Figure 4 (Not shown in the image), the spin-drying shaft 9 is a sleeve of a certain length. A second bidirectional rotary bearing 25 is provided at the first connection port of the brake wheel 19. The brake wheel 19 is connected to the outer ring of the second bidirectional rotary bearing 25, and the spin-drying shaft 9 is connected to the inner ring of the second bidirectional rotary bearing 25. The second bidirectional rotary bearing 25 only functions during the washing process, supporting the spin-drying shaft 9 to rotate in the opposite direction to the impeller shaft 10 during washing, thereby causing the inner tub and the impeller to rotate in opposite directions simultaneously.

[0052] A third bidirectional rotary bearing 5 is provided between the spin-drying shaft 9 and the upper end shell 11 to support the rotation of the spin-drying shaft 9. The third bidirectional rotary bearing 5 functions in both the spin-drying and washing processes to support the rotation of the spin-drying shaft 9.

[0053] The second bidirectional rotary bearing 25 and the third bidirectional rotary bearing 5 are arranged axially along the dehydration shaft 9. The two bidirectional bearings support the dehydration shaft 9, making the dehydration shaft 9 more stable and more stable during rotation.

[0054] The input bushing 3 includes a sleeve and a sleeve disc fixed to one end of the sleeve. The sleeve disc covers and is fixedly connected to the second connection port, that is, the input bushing 3 is fixedly connected to the second connection port. A first bidirectional rotary bearing 21 is provided between the input bushing 3 and the inner wall of the lower end shell 13 of the deceleration clutch housing, so that the brake wheel 19 can rotate in both directions.

[0055] The motor transmits power to the impeller shaft 10 and the dehydration shaft 9 through the input shaft 1 and the double planetary gear reduction mechanism.

[0056] The clutch mechanism also includes a shift fork assembly that actuates the clutch sleeve 16 in reciprocating motion and a torque sleeve 17 that is sleeved on the input shaft 1 and rotates together with the input shaft 1.

[0057] The shift fork assembly is mounted on the outside of the lower end housing 13. (Combined) Figure 1-4 As shown, the shift fork assembly 6 includes a shift fork, a shift fork seat 14, and a shift fork shaft 20. The shift fork seat 14 is fixedly mounted on the lower end shell 13 of the deceleration clutch housing. One end of the shift fork is limited on the outer periphery of the clutch sleeve 16, causing it to move axially along the input shaft sleeve 3. The middle part of the shift fork is rotatably mounted on the shift fork seat 14 through the shift fork shaft 20 to form a lever structure. The other end of the shift fork is driven by a double-stroke clutch to make the shift fork rotate around the shift fork shaft 20, thereby providing power for the shift fork to move the clutch sleeve 16.

[0058] In this embodiment, as Figure 3 As shown, the second traction device 24 is a double-stroke traction device, specifically a vertical push rod type traction device. The push rod in the second traction device can lift or lower the end of the shift fork that contacts the second traction device 24. By utilizing the lever structure of the shift fork, the clutch sleeve is moved through the other end of the shift fork.

[0059] An external spline is provided on the outer circumference of input shaft 1, such as... Figure 7 As shown, the torque sleeve 17 has an internal spline, which engages with the external spline of the input shaft 1. The torque sleeve 17 rotates synchronously with the input shaft 1. Figure 6 , Figure 7 As shown, clutch sleeve meshing teeth are provided on one end of clutch sleeve 16 near torque shaft sleeve 17, and torque shaft sleeve meshing teeth are correspondingly provided on one end of torque shaft sleeve 17 near clutch sleeve 16.

[0060] A clutch spring 15 is fitted onto the input shaft sleeve 3 for elastic reset engagement of the clutch sleeve 16. The clutch spring 15 is located between the clutch sleeve 16 and the bottom end face of the lower end shell 13. Alternatively, a limit shaft is provided radially along the input shaft sleeve 3 below the first bidirectional rotary bearing 21, with the clutch sleeve 16 located below the limit pin, and the clutch spring 15 located between the clutch sleeve 16 and the limit pin. This embodiment adopts the second method.

[0061] The clutch sleeve 16 has evenly distributed meshing teeth around its bottom circumference, with helical teeth at the lower edge and an angle of 0–15 degrees. In the installed state, the helical teeth face upwards from the dehydration direction. The torque sleeve 17 has evenly distributed meshing teeth around its circumference, with helical teeth at the upper edge. Corresponding to the clutch sleeve meshing teeth, the helical teeth angle of the torque sleeve meshing teeth is 0–15 degrees. In the installed state, the helical teeth face downwards from the dehydration direction.

[0062] A motor locking nut 2 is fitted on the input shaft 1 to fix the input shaft 1 to the motor 4, and a buffer pad 18 is provided on the end face of the torque shaft sleeve near the motor 4.

[0063] The second traction device 24 drives the shift fork assembly 6 to move, thereby actuating the clutch sleeve 16. In conjunction with the clutch spring 15, the clutch sleeve 16 reciprocates between the washing gear 12 and the torque sleeve 17. In one state, the shift fork engages the clutch sleeve 16 with the washing gear 12, locking the input sleeve 3 and thus locking the brake wheel 19. In another state, the second traction device 24 drives the shift fork to reset, and the clutch sleeve 16 moves along the axis of the input sleeve 3 to the torque sleeve 17 under the elastic force of the clutch spring 15. The clutch sleeve 16 separates from the washing gear 12, and the clutch sleeve engagement teeth of the clutch sleeve 16 engage with the torque sleeve engagement teeth of the torque sleeve 17. The input sleeve 3 and the input shaft 1 rotate synchronously.

[0064] In other embodiments, regardless of the changes in the structure and form of the dual-stroke traction device, the switching between engagement of the clutch sleeve in the deceleration clutch and engagement with the wash gear in the shift fork assembly is within the scope of protection of this invention.

[0065] Example 3

[0066] In this embodiment, the washing machine uses the dual-stroke combined with single-stroke dual traction device in Embodiment 1 and the deceleration clutch in Embodiment 2.

[0067] The washing machine includes an inner tub and a pulsator disposed inside the inner tub. The reduction mechanism includes a pulsator shaft 10, which is fixedly connected to the pulsator, and a spin-drying shaft 9 is fixedly connected to the inner tub.

[0068] The washing machine in this embodiment also includes an outer tub 22, a first traction device 23, and a brake arm 7 of the washing machine connected by a pull rope to control the braking device of the washing machine.

[0069] The first traction device 23 is connected to the brake arm 7 of the brake device, and the brake arm 7 is connected to the brake band 8. One end of the brake band 8 is fixed to the housing of the reduction clutch with screws, and the other end is fixed to one end of the brake arm 7. The brake band wraps around the outside of the brake wheel 19, and can tighten the brake wheel to stop its rotation when braking is required.

[0070] The second traction device 24 drives the shift fork assembly 6, thereby controlling the washing machine's deceleration clutch.

[0071] The first traction device 23 and the second traction device 24 are installed symmetrically or nearly symmetrically. This installation method can make more effective use of the washing machine space and maintain the balance of the washing machine.

[0072] Before entering the washing mode, the brake arm 7 is first opened by the single-stroke traction device (first traction device 23), causing the brake band 8 to loosen and not grip the brake wheel 19. Then, the shift fork is driven by the double-stroke traction device (second traction device 24), which moves the clutch sleeve 16 along the axis of the input shaft sleeve 3 to the washing gear 12. The clutch sleeve 16 engages with the washing gear 12 to lock the input shaft sleeve 3, thereby locking the brake wheel 19. Since a second bidirectional rotary bearing 25 is provided between the brake wheel 19 and the spin-dry shaft 9, the spin-dry shaft can still rotate clockwise or counterclockwise. Thus, the motor 4 transmits power to the impeller shaft 10 and the spin-dry shaft respectively through the input shaft 1 and the double planetary gear reduction mechanism. At 9 o'clock, the impeller shaft 10 and the spin-drying shaft 9 rotate in opposite directions. Since the impeller shaft 10 is connected to the impeller and the spin-drying shaft 9 is connected to the inner tub, the impeller and the inner tub can rotate in opposite directions simultaneously during the washing process to form dual power. Since the brake wheel 19 is locked at this time, the brake wheel 19 can neither rotate in the opposite direction nor in the reverse direction, so the rotation of the inner tub is not affected. The impeller and the inner tub can generate absolute dual power bidirectional washing water flow with the same bidirectional rotation angle and force. Compared with existing dual-power washing machines, even with a larger impeller, stronger motor power, and extremely fast reversal rotation, the rotation of the inner tub is still very good, providing a better dual-power washing condition.

[0073] Before entering the spin-drying state, the brake arm 7 is first opened by the single-stroke traction device, i.e., the first traction device 23, so that the brake band 8 is released and does not grip the brake wheel 19. Then, the shift fork is driven to reset by the double-stroke traction device, i.e., the second traction device 24. At this time, the clutch sleeve 16 moves along the axis of the input shaft sleeve 3 to the torque shaft sleeve 17 under the elastic force of the clutch pressure spring 15. The clutch sleeve 16 and the torque shaft sleeve 17 are engaged, and the clutch mechanism is in the engaged state. The input shaft 1, the torque shaft sleeve 17, the clutch sleeve 16, the input shaft sleeve 3 and the brake wheel 19 are connected into a whole. The input shaft sleeve 3 rotates synchronously with the input shaft 1, and the washing machine impeller and the inner tub rotate at the same speed and in the same direction, and the washing machine performs the spin-drying action.

[0074] When the washing machine is powered off, the second traction device 24 does not reset, ensuring that the clutch sleeve 16 remains in place and preventing gear damage.

[0075] When it is necessary to stop rotation, the first traction device 23 pulls the brake arm 7 of the brake device, the brake arm 7 pulls the brake band 8, and then clamps the brake wheel 19 to stop its rotation. Since the brake wheel 19 is connected to the input shaft sleeve 3, the input shaft sleeve 3 is engaged with the clutch sleeve 16, the clutch sleeve 16 is engaged with the torque shaft sleeve 17, and the torque shaft sleeve 17 is engaged with the input shaft 1, the input shaft 1 can be stopped at the same time as the motor 4 is de-energized to make the input shaft 1 lose power, thereby stopping the impeller and the inner drum from rotating.

[0076] This invention relates to a dual-stroke traction device, a reduction clutch, and a washing machine that works in conjunction with a single-stroke traction device. Through this dual-stroke traction device and a suitable reduction clutch, the brake wheel is locked and does not rotate during the washing process. The inner tub and pulsator of the washing machine can rotate simultaneously in both directions, generating bidirectional counter-current water flow. Even when the pulsator is large, the motor power is excessive, or there is a rapid reversal, the inner tub can still rotate well to generate a strong counter-current water flow, thereby improving the washing machine's cleaning effect, reducing abnormal noise from the brake wheel, and extending the lifespan of the braking system and other related components.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
