Description

Washing machine deceleration clutch and washing machine TECHNICAL FIELD

[0001] The present application belongs to the field of washing machines, and in particular relates to a washing machine deceleration clutch and a washing machine. BACKGROUND

[0002] The washing machine double-power deceleration clutch can realize that the rotation direction of the dehydration shaft and the inner barrel connected thereto is opposite to the rotation direction of the impeller shaft, and the actual application effect is that the impeller and the inner barrel rotate at the same time, but the rotation directions of the two are opposite, forming double-direction power.

[0003] When the washing machine is in a washing working condition, the conventional double-power deceleration clutch brake wheel is braked clockwise by relying on the brake belt to hold tightly, and is braked counterclockwise by relying on the one-way bearing to lock, the motor drives the dehydration shaft and the impeller shaft to rotate bidirectionally at the same time through the double-planetary gear deceleration mechanism, and bidirectional counter-flow is generated; however, when the motor power is too large or fast commutation, the brake wheel follows the rotation at a large angle clockwise because the brake belt cannot hold the brake wheel tightly, the dehydration shaft and the dehydration inner barrel connected thereto rotate counterclockwise reversely at a weak angle, or even cannot rotate counterclockwise reversely, and then the function and effect of the double-power decelerator are lost, and the user experience is affected.

[0004] A Chinese patent with the application number CN202010699552.1 discloses a washing machine deceleration clutch device and a washing machine, but it cannot realize the washing effect of locking the brake wheel when the inner barrel and the impeller rotate reversely at the same time.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a washing machine deceleration clutch which can ensure that the brake wheel does not follow the rotation under the washing working condition, and improve the washing effect.

[0007] The present application also provides a washing machine which can improve the washing effect and reduce the noise.

[0008] To solve the above technical problems, the basic idea of the technical solution of the present application is as follows:

[0009] A washing machine deceleration clutch, a first connecting port of a brake wheel is provided with a second bidirectional rotation bearing, the brake wheel is connected with the outer ring of the second bidirectional rotation bearing, and a dehydration shaft is connected with the inner ring of the second bidirectional rotation bearing.

[0010] Further, a first bidirectional rotation bearing is arranged between the input shaft sleeve and the lower end shell inner wall of the shell of the deceleration clutch.

[0011] Further, the clutch sleeve has two working positions, and is engaged with the washing gear and the torque sleeve respectively in the two working positions; when the clutch sleeve is engaged with the washing gear, the dehydration shaft and the pulsator shaft rotate reversely at the same time, and the brake wheel is locked; when the clutch sleeve is engaged with the torque sleeve, the dehydration shaft and the pulsator shaft rotate in the same direction.

[0012] The washing machine comprises the double-travel single-travel double-puller and the washing machine speed reduction clutch.

[0013] The first puller is a single-travel puller and controls the brake device of the washing machine.

[0014] The second puller is a double-travel puller and controls the action of the yoke of the washing machine speed reduction clutch.

[0015] Further, the first puller and the second puller are installed at the bottom of the outer tub of the washing machine, and the installation positions of the two pullers are symmetrical or close to symmetrical.

[0016] Further, in the washing process, the brake wheel of the washing machine speed reduction clutch is locked and does not rotate.

[0017] Further, before entering the washing working condition, the brake arm of the brake device is opened through the first puller, and then the yoke is driven to act through the second puller, so that the clutch sleeve is engaged with the washing gear to lock the input sleeve, and thus the brake wheel is locked.

[0018] Further, before entering the dehydration working condition, the brake arm of the brake device is opened through the first puller, and then the yoke is driven to reset through the second puller, so that the clutch sleeve is engaged with the torque sleeve under the elastic force of the clutch spring.

[0019] Further, when the washing machine is powered off, the second puller is not reset.

[0020] Compared with the prior art, the washing machine speed reduction clutch and the washing machine have the following beneficial effects.

[0021] In the washing process, the brake wheel of the washing machine speed reduction clutch is locked and does not rotate, the inner tub and the pulsator of the washing machine can rotate in two directions at the same time to generate bidirectional water flow, even when the pulsator is large, the motor power is too large or the direction is quickly changed, the inner tub can still rotate well to generate relatively strong water flow, so that the washing effect of the washing machine is improved, the follow-up noise of the brake wheel of the washing machine is reduced, and the service life of the brake system and other related components is improved.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In order to solve the problem that in the existing conventional double-power deceleration clutch, when the motor power is too large or quickly reversed during the washing process, the brake band cannot effectively brake the brake wheel, resulting in the brake wheel following rotation, and further resulting in the weak reverse rotation angle of the dewatering shaft and the dewatering inner drum connected thereto, or even the inability to rotate counterclockwise, the present application proposes a washing machine double-stroke matching single-stroke double-puller, a washing machine deceleration clutch and a washing machine.

[0037] Embodiment one

[0038] In this embodiment, the washing machine double-stroke matching single-stroke double-puller, wherein the first puller 23 is a single-stroke puller, and the second puller 24 is a double-stroke puller. When the two pullers are installed at the bottom of the outer drum of the washing machine, the first puller 23 and the second puller 24 are installed symmetrically or close to symmetrically.

[0039] The first puller 23 is connected to the brake arm 7 of the washing machine through a pull rope to control the brake device of the washing machine. As shown in FIG. 3, the brake device includes the brake arm 7 and the brake belt 8, and the first puller 23 pulls the brake arm 7 through the pull rope, and the brake arm 7 pulls the brake belt 8 to brake the brake wheel. When the washing machine needs to stop rotating, the first puller 23 acts by pulling the brake arm 7 to make the brake belt 8 act to tightly hold the brake wheel to stop rotating.

[0040] The second puller 24 drives the fork assembly 6 to control the washing machine deceleration clutch, so as to lock the brake wheel in the washing program, and unlock the brake wheel to make it active in the dewatering program.

[0041] Embodiment two

[0042] The application further provides a washing machine deceleration clutch, which comprises a deceleration mechanism, a clutch mechanism and a locking mechanism.

[0043] The deceleration mechanism comprises a brake wheel 19 capable of rotating in two directions, an input shaft 1, a dehydration shaft 9, an input shaft sleeve 3 and a double planetary gear deceleration mechanism, and the input shaft 1 is coaxially arranged in the input shaft sleeve 3.

[0044] The clutch mechanism comprises a clutch sleeve 16 coaxially arranged on the input shaft sleeve 3 and capable of reciprocating along the axial direction of the input shaft sleeve 3.

[0045] The locking mechanism is used for locking the input shaft sleeve 3 and further locking the brake wheel 19.

[0046] The locking mechanism comprises a washing tooth rack 12 fixedly arranged outside the input shaft sleeve 3, as shown in FIG. 4, the washing tooth rack 12 and the input shaft sleeve 3 are coaxially arranged, but the washing tooth rack 12 and the input shaft sleeve 3 do not contact each other, and the washing tooth rack 12 is fixed on the shell of the deceleration clutch. In order to realize the fixed arrangement of the washing tooth rack 12, the deceleration clutch of the embodiment further comprises a shell with an internal cavity, which comprises an upper end shell 11 and a lower end shell 13, and the two shells are connected to form the internal cavity. The brake wheel 19 is arranged in the internal cavity of the shell, the shell has a shell inlet for the input shaft sleeve 3 to pass through, and the washing tooth rack 12 is fixed on the shell and located outside the inlet of the lower end shell 13 of the shell.

[0047] The outer periphery of the input shaft sleeve 3 is provided with axially extending outer teeth, as shown in FIG. 6, the inner periphery of the clutch sleeve 16 is provided with axially extending inner teeth, and the outer teeth of the input shaft sleeve 3 and the inner teeth of the clutch sleeve 16 are meshed.

[0048] As shown in FIG. 4, the clutch sleeve 16 and the washing tooth rack 12 are coaxially arranged outside the input shaft sleeve 3 and arranged in the axial direction of the input shaft sleeve 3, and in the state that the washing machine deceleration clutch is installed on the washing machine, the washing tooth rack 12 is above and the clutch sleeve 16 is below. As shown in FIGS. 4, 5 and 6, the washing tooth rack 12 comprises an annular body, a washing meshing tooth is arranged at one end of the annular body close to the clutch sleeve 16, and an upper meshing tooth is arranged at one end of the clutch sleeve 16 close to the washing tooth rack 12. When the upper meshing tooth of the clutch sleeve 16 is meshed with the washing meshing tooth of the washing tooth rack 12, the washing tooth rack 12 cannot rotate because it is fixed on the shell of the deceleration clutch, the inner teeth of the clutch sleeve 16 and the outer teeth of the input shaft sleeve 3 are meshed, and the input shaft sleeve 3 is locked, and at the same time, the brake wheel 19 is also braked because the input shaft sleeve 3 is fixedly connected with the brake wheel 19.

[0049] When the clutch sleeve 16 moves along the axial direction of the input shaft sleeve 3, when the clutch sleeve 16 is close to the washing tooth rack 12, the two are in contact and meshed through the meshing teeth, and when the clutch sleeve 16 is away from the washing tooth rack 12, the two are separated and the meshing is removed.

[0050] In the washing process, the deceleration clutch drives the simultaneous opposite rotation of the pulsator shaft and the dehydration shaft through the double planetary gear deceleration mechanism inside it, and the input shaft sleeve 3 is locked through 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 that in the washing process, the pulsator connected with the pulsator shaft rotates, the inner barrel connected with the dehydration shaft rotates, and the pulsator and the inner barrel rotate simultaneously and oppositely, and the brake wheel does not rotate.

[0051] The brake wheel 19 has a first connecting port and a second connecting port at both ends, and an accommodating cavity is formed inside the brake wheel 19 between the first connecting port and the second connecting port. A double planetary gear deceleration mechanism (not shown in FIG. 4) is arranged in the accommodating cavity. The dehydration shaft 9 is a sleeve with a certain length. The first connecting port of the brake wheel 19 is provided with a second double-direction rotating bearing 25. The outer ring of the second double-direction rotating bearing 25 is connected with the brake wheel 19, and the inner ring of the second double-direction rotating bearing 25 is connected with the dehydration shaft 9. The second double-direction rotating bearing 25 only functions during the washing process, and is used to support the opposite rotation of the dehydration shaft 9 relative to the pulsator shaft 10, so that the inner barrel and the pulsator rotate simultaneously and oppositely.

[0052] A third double-direction rotating bearing 5 is arranged between the dehydration shaft 9 and the upper end shell 11, and is used to support the rotation of the dehydration shaft 9. The third double-direction rotating bearing 5 functions in the dehydration process and the washing process, and supports the rotation of the dehydration shaft 9.

[0053] The second double-direction rotating bearing 25 and the third double-direction rotating bearing 5 are arranged axially along the dehydration shaft 9. The two double-direction bearings support the dehydration shaft 9, so that the dehydration shaft 9 is more stable in rotation.

[0054] The input shaft sleeve 3 includes a sleeve and a sleeve disc fixed at one end of the sleeve. The sleeve disc covers and is fixedly connected with the second connecting port, that is, the input shaft sleeve 3 is fixedly connected with the second connecting port. A first double-direction rotating bearing 21 is arranged between the input shaft sleeve 3 and the inner wall of the lower end shell 13 of the shell of the deceleration clutch, so that the brake wheel 19 can rotate in two directions.

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

[0056] The clutch mechanism further includes a shift fork assembly reciprocating with the shift clutch sleeve 16 and a torque sleeve 17 sleeved on the input shaft 1 and rotating with the input shaft 1.

[0057] The shift fork assembly is mounted outside the lower end shell 13. As shown in Figs. 1-4, the shift fork assembly 6 comprises a shift fork, a shift fork seat 14 fixedly mounted on the lower end shell 13 of the housing of the reduction clutch, and a shift fork pivot 20. One end of the shift fork is positioned on the outer periphery of the clutch sleeve 16 to shift it along the input shaft sleeve 3, the middle part of the shift fork is rotatably mounted on the shift fork seat 14 to form a lever structure, and the other end of the shift fork is provided with a driving force by a double-throw clutch to rotate the shift fork around the shift fork pivot 20, thereby providing power for the shift fork to shift the clutch sleeve 16.

[0058] In this embodiment, as shown in Fig. 3, the second puller 24 is a double-throw puller, specifically an up-and-down top rod movement type puller. The top rod in the second puller can be raised or lowered to lift or lower the end of the shift fork in contact with the second puller 24, and the lever structure of the shift fork is utilized to shift the clutch sleeve by the other end of the shift fork.

[0059] The outer periphery of the input shaft 1 is provided with external splines, as shown in Fig. 7, the torque shaft sleeve 17 has internal splines, the internal splines of the torque shaft sleeve 17 are engaged with the external splines of the input shaft 1, and the torque shaft sleeve 17 rotates synchronously with the input shaft 1. As shown in Figs. 6 and 7, the end of the clutch sleeve 16 close to the torque shaft sleeve 17 is provided with clutch sleeve engaging teeth, and the end of the torque shaft sleeve 17 close to the clutch sleeve 16 is correspondingly provided with torque shaft sleeve engaging teeth.

[0060] The input shaft sleeve 3 is sleeved with a clutch compression spring 15 for elastic reset engagement of the clutch sleeve 16. The clutch compression spring 15 is arranged between the clutch sleeve 16 and the bottom end face of the lower end shell 13, or a limiting pin is arranged radially along the input shaft sleeve 3 below the first double-throw bearing 21, the clutch sleeve 16 is located below the limiting pin, and the clutch compression spring 15 is arranged between the clutch sleeve 16 and the limiting pin. The second mode is adopted in this embodiment.

[0061] The clutch sleeve engaging teeth of the clutch sleeve 16 are uniformly distributed along the bottom end periphery of the clutch sleeve 16, the lower edge of the teeth is an inclined tooth with an angle of 0-15 degrees. In the installed state, the direction of the inclined tooth is from low to high in the direction of dehydration. The torque shaft sleeve engaging teeth of the torque shaft sleeve 17 are uniformly distributed around the periphery, the upper edge of the teeth is an inclined tooth corresponding to the clutch sleeve engaging teeth, and the angle of the inclined tooth of the torque shaft sleeve engaging teeth is 0-15 degrees. In the installed state, the direction of the inclined tooth is from high to low in the direction of dehydration.

[0062] The input shaft 1 is sleeved with a motor locking nut 2 for fixed connection of the input shaft 1 and the motor 4, and a buffer pad 18 is arranged on the end face of the torque shaft sleeve close to the motor 4.

[0063] The driving fork assembly 6 is driven by the second traction device 24 to actuate the clutch sleeve 16, and the clutch spring 15 is engaged to make the clutch sleeve 16 reciprocate between the washing tooth rack 12 and the torque sleeve 17: in one state, the driving fork actuates the clutch sleeve 16 to engage with the washing tooth rack 12 to lock the input sleeve 3, thereby locking the brake wheel 19; in another state, the second traction device 24 drives the driving fork to reset, and the clutch sleeve 16 moves along the axis of the input sleeve 3 under the elastic force of the clutch spring 15 to the torque sleeve 17, the clutch sleeve 16 is separated from the washing tooth rack 12, and the clutch sleeve engagement teeth of the clutch sleeve 16 are engaged with the torque sleeve engagement teeth of the torque sleeve 17, so that the input sleeve 3 rotates synchronously with the input shaft 1.

[0064] In other embodiments, regardless of the transformation of the double-stroke traction device structure and form, the driving fork assembly actuates the clutch sleeve in the speed reduction clutch to switch between engagement with the torque sleeve and engagement with the washing tooth rack, which is within the scope of the present application.

[0065] Embodiment Three

[0066] In this embodiment, the washing machine uses the double-stroke and single-stroke double traction device in Embodiment One and the speed reduction clutch in Embodiment Two.

[0067] The washing machine comprises an inner tub and a pulsator arranged in the inner tub, and the speed reduction mechanism comprises a pulsator shaft 10 fixedly connected with the pulsator and a dehydration shaft 9 fixedly connected with the inner tub.

[0068] The washing machine of the present embodiment further comprises an outer tub 22, a first traction device 23 connected with a brake arm 7 of the washing machine through a pull rope to control a brake device of the washing machine.

[0069] The first traction device 23 is connected with the brake arm 7 of the brake device, and the brake arm 7 is connected with a brake belt 8. One end of the brake belt 8 is fixed to the housing of the speed reduction clutch by a screw, and the other end is fixed to one end of the brake arm 7. The brake belt is wrapped outside the brake wheel 19 and can tightly hold the brake wheel to stop its rotation when braking is needed.

[0070] The second traction device 24 drives the driving fork assembly 6 to control the speed reduction clutch of the washing machine.

[0071] The first traction device 23 and the second traction device 24 are symmetrically or nearly symmetrically installed, which can more effectively utilize the space of the washing machine and maintain the balance of the washing machine.

[0072] Before entering the washing condition, the brake arm 7 is first opened by the single-stroke tractor, i.e., the first tractor 23, so that the brake band 8 is loosened and does not tightly hold the brake wheel 19. Then the double-stroke tractor, i.e., the second tractor 24, is used to drive the shift fork to move the clutch sleeve 16 along the axis of the input shaft sleeve 3 to the washing gear rack 12. The clutch sleeve 16 is locked with the washing gear rack 12, and the input shaft sleeve 3 is locked with the brake wheel 19. Since the second double-direction rotating bearing 25 is arranged between the brake wheel 19 and the dewatering shaft 9, the dewatering shaft can still rotate clockwise or counterclockwise. Therefore, when the motor 4 transmits power to the pulsator shaft 10 and the dewatering shaft 9 through the input shaft 1 and the double-planetary-gear deceleration mechanism, the pulsator shaft 10 and the dewatering shaft 9 rotate in opposite directions. Since the pulsator shaft 10 is connected with the pulsator and the dewatering shaft 9 is connected with the inner drum, the pulsator and the inner drum rotate in opposite directions to form double power in the washing condition. Since the brake wheel 19 is locked, it cannot rotate in the opposite direction, so the rotation of the inner drum is not affected, and the pulsator and the inner drum can generate absolute double-power bidirectional washing water flow. The bidirectional rotation angle is the same, and the force is also the same. Compared with the existing double-power washing machine, even in the case of a large pulsator, strong motor power, and extremely fast reverse rotation, the rotation of the inner drum is still very good, and a good double-power washing condition can be provided.

[0073] Before entering the dewatering condition, the brake arm 7 is first opened by the single-stroke tractor, i.e., the first tractor 23, so that the brake band 8 is loosened and does not tightly hold the brake wheel 19. Then the double-stroke tractor, i.e., the second tractor 24, is used to drive the shift fork to reset. 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 compression spring 15. The clutch sleeve 16 is engaged with the torque shaft sleeve 17, 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 as a whole. The input shaft sleeve 3 rotates synchronously with the input shaft 1, and the washing machine pulsator and the inner drum rotate at the same speed in the same direction. The washing machine performs the dewatering action.

[0074] When the washing machine is powered off, the second tractor 24 is not reset, ensuring that the position of the clutch sleeve 16 does not move, and avoiding gear teeth.

[0075] When it is necessary to stop rotating, the first tractor 23 is used to act on the brake arm 7 of the brake device to pull the brake band 8, which in turn tightly holds the brake wheel 19 to stop its rotation. Since the brake wheel 19 is connected with the input shaft sleeve 3, the input shaft sleeve 3 is tooth-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 when the motor 4 is powered off and loses power, so that the pulsator and the inner drum stop rotating.

[0076] In other embodiments, the washing machine includes the double-puller of double-stroke matching single-stroke in the first embodiment, which can be used in the washing machine with the existing speed-reducing clutch.

[0077] In other embodiments, the washing machine includes the speed-reducing clutch in the second embodiment, which can be used in the washing machine with the existing puller.

[0078] The washing machine speed-reducing clutch and the washing machine of the present application, by the double-puller of double-stroke matching single-stroke and the matched speed-reducing clutch, the brake wheel is locked in the washing process, the inner barrel and the pulsator can rotate in both directions to generate double-directional water flow, even when the pulsator is large, the motor power is too large or the fast commutation, the inner barrel can still rotate well to generate strong water flow, thereby improving the washing effect of the washing machine, reducing the follow-up noise of the brake wheel, and improving the service life of the brake system and other related components.

[0079] The above description is only the preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with the preferred embodiment, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and the equivalent embodiments of the equivalent changes can be obtained.
