Description

Technical Field

[0001] This application relates to a deceleration clutch structure in the field of household appliances, and more particularly to a clothing processing device equipped with the aforementioned deceleration clutch structure, as well as a control method for the aforementioned clothing processing device. Background Technology

[0002] In top-loading and front-loading washing machines, the drain motor opens the drain valve during drainage, allowing water in the tank to flow out of the washing machine through the drain pipe. Traditional drain valves in laundry equipment are single-stroke. After the drain motor completes its stroke, it applies traction to the valve core via a pull rope, causing the valve core to open synchronously, and water begins to flow out of the tank.

[0003] However, the drain motor of clothing processing equipment, especially the pulsator washing machine, is not only used to open the valve core of the drain valve, but also needs to open the clutch arm of the deceleration clutch structure so that the washing tub can run at high speed during the spin-drying process.

[0004] To achieve the above functions, existing garment processing equipment generally uses a dual-stroke drain motor, with the two strokes acting on the valve core of the drain valve and the clutch arm of the reduction clutch structure, respectively. However, this results in a longer stroke for the clutch arm, which can cause interference between the clutch arm and other components, especially with the stator of the drive motor.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] This application discloses a clothing processing device for washing clothing. The clothing processing device can be any existing washing machine, washer-dryer combo, dryer, etc. The clothing processing device generally includes: a water tank 300 for holding the washing water; and an agitation structure installed in the water tank 300 to agitate the incoming washing water, such as a washing tub, impeller, stirring column, etc.

[0046] In this embodiment of the application, for ease of description, a pulsator washing machine is used as an example for discussion:

[0047] like Figures 1 to 5As shown, the water tank 300 adopts an outer tank with a vertically extending shaft. The top is open with a tank opening, and the bottom is closed and connected to a drain pipe. A drain valve 204 is installed on the drain pipe to control its opening and closing, thus enabling water to be stored in the water tank 300 or discharged outwards. Simultaneously, a washing tub is coaxially installed inside the water tank 300. The washing tub has an upward-facing opening and a closed bottom, used to hold clothes to be washed. Dehydration holes are arranged on the tub wall and bottom, connecting the inside and outside of the washing tub, allowing the washing water in the water tank 300 to flow inside and outside the washing tub, achieving the effect of washing, dehydrating, and draining clothes by creating a water flow within the washing tub. In addition, the washing tub is equipped with a pulsator, which is located above the bottom of the tub and is rotatably installed inside. The upper surface of the pulsator has agitator ribs with a concave-convex structure. The rotation of the pulsator causes the agitator ribs to stir the washing water in the water tank 300, forming a washing water flow. Of course, in order to drive the washing tub and / or pulsator to rotate, the washing machine also includes a drive motor 5. The drive motor 5 is connected to the pulsator and / or washing tub via a reduction clutch structure 100. The reduction clutch structure 100, which can switch the transmission mode, allows the drive motor 5 to drive the pulsator and / or washing tub to rotate around an axis, thereby changing the working state of the clothes handling equipment and creating different water flow patterns in the water tank 300 to achieve the effects of washing and dehydrating the clothes in the washing tub.

[0048] Of course, in this embodiment of the application, in order to control the opening and closing of the drain valve 204 and the drain pipe, a drain motor 201 is also provided on the garment processing equipment. The drain motor 201 is connected to the valve core 243 of the drain valve 204, so that after the drain motor 201 works and generates a stroke, it can pull the valve core 243 of the drain valve 204 to move, thereby causing the valve core 243 to move and open the drain valve 204. Alternatively, when the drain motor 201 does not work and does not generate a stroke, it can cause the valve core 243 of the drain valve 204 to move back to its original position, so that the valve core 243 returns to its original position and closes the drain valve 204.

[0049] In order to switch the drive mode of the impeller and / or the washing tub, the reduction clutch structure 100 needs to apply a clutch action to change the transmission mode of the reduction clutch structure 100. To achieve the above effect, the following can be adopted:

[0050] like Figures 1 to 5As shown, the deceleration clutch structure 100 includes a deceleration structure 2, which constitutes a deceleration transmission structure. Generally, the deceleration structure 2 is set as a transmission wheel system that drives the input shaft and the output shaft. The rotor 501 of the drive motor 5 meshes with the input end of the deceleration structure 2, and the output end of the deceleration structure 2 meshes with the impeller and / or the washing tub, so that the rotor 501 drives the impeller and / or the washing tub to rotate through the deceleration structure 2 during rotation. Meanwhile, the reduction clutch structure 100 also includes a clutch structure 1, which includes a clutch arm 12 and a clutch tooth 11. The clutch tooth 11 is disposed on any transmission component of the reduction structure 2. The clutch arm 12 is movably mounted on the mounting shell of the reduction clutch structure 100. The clutch arm 12 and the clutch tooth 11 can be controllably separated or engaged to change the transmission mode of the reduction structure 2. After the clutch arm 12 and the clutch tooth 11 are engaged, the washing tub and the water tank 300 are relatively fixed, and the washing tub can no longer be driven to rotate by the drive motor 5. After the clutch arm 12 and the clutch tooth 11 are separated, the washing tub is connected to the drive motor 5 through the reduction structure 2, so that the drive motor 5 drives the washing tub and the impeller to rotate simultaneously through the reduction structure 2, thereby achieving the effect of the washing tub and the impeller rotating together. In addition, the deceleration clutch structure 100 also includes a housing, which is generally composed of a mounting plate 4 and a housing 3. The deceleration structure 2 is set inside the housing, and the clutch arm 1 of the clutch structure is movable on the housing 3. At the same time, the housing 3 is mounted on the mounting plate 4, and the mounting plate 4 is fixed below the bottom of the water tank 300 to achieve coaxial installation of the deceleration clutch structure 100 and the water tank 300.

[0051] In this embodiment of the application, in order to drive the movement of the clutch arm 12, the following can be used:

[0052] The clutch arm 12 is rotatably mounted on the housing 3 of the reduction clutch structure 100. The housing 3 is mounted on a mounting plate 4 fixedly mounted below the bottom of the water tank 300, so that the housing 3 of the reduction clutch structure 100 is fixedly mounted on the mounting plate 4. The middle part of the clutch arm 12 is rotatably mounted on the housing 3 via a vertically extending shaft. The second end of the clutch arm 12 is a plug-in connection part 17 facing the outer periphery of the water tank 300. The plug-in connection part 17 is connected to the driven component formed by the drain motor 201, so that the clutch arm 12 can rotate around the shaft. The clutch arm 12 is mounted on the housing 3. The first end of the clutch arm 12 is a clutch end facing the center of the water tank 300, and is provided with a clutch pawl 16. The deceleration structure 2 of the deceleration clutch structure 100 is provided with a clutch gear, and the outer periphery of the clutch gear is provided with clutch teeth 11. The clutch pawl 16 and the clutch teeth 11 can be separated or engaged. The housing 3 of the deceleration structure 2 is mounted on the lower side of the mounting plate 4. The clutch arm 12 is mounted on the housing 3 and can be rotated around the axis by the return spring 18. The return spring 18 provides the clutch arm 12 with a reset movement to or maintains the initial position of engaging the clutch teeth 11.

[0053] In order to realize the movement of the clutch arm 12, the clutch arm 12 is generally connected to the drain motor 201 of the drain valve structure 200. The drain motor 201 is used as the driven component. The stroke of the drain motor 201 synchronously pulls the clutch arm 12 to generate rotation around the axis, so as to realize the clutch arm 12's clutch action and achieve the effect of controlling the clutch pawl 16 of the clutch arm 12 to engage or disengage with the clutch teeth 11 of the reduction structure 2.

[0054] In this embodiment of the application, in order to achieve the drive connection between the clutch arm 12 and the drainage motor 201, the following structure can be adopted:

[0055] like Figures 1 to 5 As shown, the output end of the drain motor 201 is connected to the valve core 243 of the drain valve 204 via a pull rope 202. The pull rope 202 is provided with a connector 203, which is connected to the plug-in connection part 17 at the second end of the clutch arm 12. After the drain motor 201 generates a stroke action, it pulls the valve core 243 via the pull rope to move, so that the valve core 243 opens the drain pipe accordingly. During the process of pulling the pull rope 202, the clutch arm 12 is pulled synchronously, causing the clutch arm 12 to rotate around the axis to form a clutch action. This causes the clutch claw part 16 and the clutch tooth 11 at the first end of the clutch arm 12 to engage or disengage, thereby changing the working state of the reduction structure 2 of the reduction clutch structure 100, so that the drive motor 5 can switch to drive the impeller and / or the washing tub to rotate via the reduction structure 2.

[0056] In this embodiment of the application, in order to reduce the space occupied by the deceleration clutch structure 100, the deceleration clutch structure 100 is generally configured as follows: the deceleration clutch structure 100 includes a drive motor 5, a deceleration structure 2, a clutch structure 1 and a mounting plate 4; the drive motor 5 includes a rotor 501 and a stator 502, and after being powered on, the rotor 501 can be driven to rotate around the axis by electromagnetic driving force. The rotor 501 is rotatably connected to the deceleration structure 2 around the axis, and the stator 502 is fixedly mounted on the mounting plate 4. The clutch arm 12 of the clutch structure 1 passes through the stator 502, which is ring-shaped. The ring-shaped stator 502 has a notch 503 for the clutch arm 12 to pass through. The clutch arm 12 is horizontally rotatable and mounted on the mounting plate 4. The first end of the clutch arm 12 extends into the hollow portion of the ring-shaped stator 502, and the clutch pawl 16 at the first end engages or disengages with the clutch teeth 11 of the reduction structure 2. The second end of the clutch arm 12 is located outside the ring-shaped stator 502, and the second end is inserted... The connecting part 17 is inserted into the insertion hole 231 on the connector 203. The connector 203 extends in the horizontal direction of the pull rope 202. The connector 203 is provided with a insertion hole 231 that is hollowed out in the radial direction perpendicular to the pulling direction of the pull rope 202. The insertion connecting part 17 at the second end of the clutch arm 12 is inserted into the insertion hole 231, so that when the connector 203 moves synchronously with the pull rope 202, it can drive the clutch arm 12 to produce a clutch action that rotates around the axis. In particular, to prevent separation or jamming at the insertion point of the second end of the clutch arm 12 and the insertion hole 231 of the connector 203 during the rotational clutch action, the insertion hole 231 is generally set as an elongated hole with a certain length along the pulling direction, and the size of the insertion hole 231 is larger than the size of the second end of the clutch arm 12 in the pulling direction. This allows the clutch arm 12 to slide relative to the insertion hole 231 during the pulling process, so that the clutch arm 12 can generate a smooth synchronous rotational clutch action when pulled by the connector 203.

[0057] In this embodiment, to achieve the goal of using the drain motor 201 to pull the drain valve 204 and the reduction clutch structure 100 respectively, the drain motor 201 needs to be configured with two strokes, so that the two strokes correspond to the clutch arm 12 of the reduction clutch structure 100 to produce a clutch action, and to the valve core 243 of the drain valve 204 to produce an action to open the drain pipe. To achieve the above-mentioned dual-stroke motor drive, the following solution is generally adopted:

[0058] The drainage motor 201 has two strokes that are executed sequentially: a first stroke and a second stroke.

[0059] After the drain motor 201 performs its first stroke, it pulls the connector 203 via the pull rope 202, and the connector 203 pulls the valve core 243 of the drain valve 204 to produce the first action. After the valve core 243 produces the first action, it will not open the drain pipe. At the same time, the connector 203 drives the clutch arm 12 to produce a clutch action. The clutch claw 16 at the first end of the clutch arm 12 separates from the clutch teeth 11 on the reduction structure 2. The drive motor 5 drives the washing tub and the impeller to rotate simultaneously via the reduction structure 2.

[0060] After the drain motor 201 performs its first stroke, it operates again to generate a second stroke. The drain motor 201 pulls the connector 203 via the pull rope 202, and the connector 203 pulls the valve core 243 of the drain valve 204 to generate a second action. After the valve core 243 generates a second action, it opens the drain pipe. At the same time, the connector 203 drives the clutch arm 12 to generate another action. The clutch pawl 16 at the first end of the clutch arm 12 remains separated from the clutch teeth 11 on the reduction structure 2. The drive motor 5 drives the washing tub and the impeller to rotate simultaneously via the reduction structure 2.

[0061] However, in the above process, since the clutch arm 12 is installed by passing through the notch 503 of the stator 502 of the drive motor 5, the space for the clutch arm 12 to engage and disengage is limited. During the second stroke, the clutch arm 12 will interfere with the stator 502. In order to avoid the above problem, the following settings are made in this embodiment:

[0062] A buffer unit 13 is provided at the clutch arm 12 of the deceleration clutch structure 100. The buffer unit 13 is used to counteract the pulling displacement of the clutch arm 12 by the second stroke of the drainage motor 201, so that the clutch arm 12 itself generates elastic deformation, and avoids the clutch arm 12 from having excessive displacement due to the second stroke.

[0063] To achieve the aforementioned elastic deformation, the buffer unit 13 can be constructed using any structure in the prior art, such as any or a combination of elastic telescopic joint structures, elastic rotary joint structures, etc., so that the clutch arm 12 itself can generate elastic telescopic deformation and / or rotational deformation. When the second stroke of the drainage motor 201 pulls the clutch arm 12 to move, the elastic deformation reduces the activity space, thereby achieving significant technical progress in reducing the size of the notch 503 on the drive motor 5 and preventing interference between the clutch arm 12 and the drive motor 5.

[0064] In this embodiment, the clutch arm 12 is provided with, and / or a buffer unit 13 is provided at the connection point between the clutch arm 12 and the reduction clutch structure 100. The buffer unit 13 provides elastic buffering for the clutch action of the clutch arm 12, thereby counteracting the pulling action generated by the second stroke of the drainage motor 201. Through the above arrangement, the clutch arm can generate elastic deformation with the help of the elastic buffer unit, so as to ensure that the clutch arm meets the effect of secondary traction of the drainage motor without increasing the circumferential dimension of the stator notch.

[0065] In this embodiment, the following configuration is used: a buffer unit 13 is provided on the clutch arm 12 of the deceleration clutch structure 100 to counteract the displacement of the clutch arm 12 caused by the pull of the drainage motor 201 during the second stroke.

[0066] In this embodiment, the clutch arm 12 has a first clutch support arm 121 and a second clutch support arm 122; the first clutch support arm 121 and the second clutch support arm 122 are connected by a buffer unit 13; the end of the first clutch support arm 121 has a clutch pawl portion 16 that engages or disengages with the clutch teeth 11 of the deceleration clutch structure 100; the second clutch support arm 122 is rotatably connected to the housing 3 of the deceleration clutch structure 100; the end of the second clutch support arm 122 is provided with a plug-in connection portion 17, which is connected to the drain valve structure 200 and is used to drive the clutch arm 12 to move by the stroke of the drain motor 201.

[0067] In this embodiment, the buffer unit 13 includes an elastic pivoting unit 14. The first clutch arm 121 and the second clutch arm 122 are pivotally connected relative to each other via the pivoting shaft 141 of the elastic pivoting unit 14. An elastic element 142 is provided at the pivoting shaft 141 of the elastic pivoting unit 14 to provide a restoring force for the pivoting action between the first clutch arm 121 and the second clutch arm 122. The pivoting shaft 141 of the elastic pivoting unit 14 and the rotation axis between the second clutch arm 122 and the housing 3 are both set to extend vertically. The elastic element 142 is a torsion spring, which is sleeved on the pivoting shaft 141. The two ends of the torsion spring are respectively connected to the first clutch arm 121 and the second clutch arm 122 to provide a restoring force to keep the two clutch arms in their initial positions.

[0068] In this embodiment of the application, the buffer unit 13 further includes a one-way limiting unit 15; the one-way limiting unit 15 is used to cooperate with the elastic member 142 to limit the first clutch support arm 121 and the second clutch support arm 122 to remain in and / or return to the reset position.

[0069] In this embodiment, the limiting unit 15 is disposed on the side of the first clutch support arm 121 facing the disengagement clutch tooth 12, and is used to limit the excessive reset movement of the first clutch support arm 121 and the second clutch support arm 122 under the action of the elastic member 142. Optionally, the limiting unit 15 includes a limiting part 151, which is disposed on the second clutch support arm 122. The limiting part 151 is located on the side of the pivot shaft 141 facing the direction of the disengagement clutch tooth 12 of the first clutch support arm 121. At least a portion of the limiting part 151 is disposed at the same height as the first clutch support arm 121, so that the first clutch support arm 121 reset to the initial position under the action of the elastic member 142 can be limited to contact with the limiting part 151, thereby limiting the first clutch support arm 121 and the second clutch support arm 122 pushed by the elastic member 142 from abutting each other, thereby achieving the effect of keeping the first clutch support arm 121 and the second clutch support arm 122 in the initial position.

[0070] like Figure 4 As shown, after the drainage motor 201 performs the first stroke and pulls the plug-in connection part 17 of the second clutch support arm 122 to produce a clutch action, the second clutch support arm 122 drives the first clutch support arm 121 to rotate together, so that the clutch pawl part 16 on the first clutch support arm 121 separates from the clutch tooth 11.

[0071] like Figure 5 As shown, after the drainage motor performs the second stroke and pulls the plug-in connection 17 of the second clutch support arm to generate a secondary action, the second clutch support arm 122 rotates independently. Due to the limitation of the stator 502 of the drive motor 5, the first clutch support arm 121 deforms and rotates around the pivot axis, so that the first clutch support arm 121 remains in the position separated from the clutch teeth 11. Thus, the clutch arm 12 is guaranteed to meet the secondary traction stroke without increasing the circumferential size of the notch 503.

[0072] In this embodiment of the application, in order to achieve the effect of deforming the clutch arm 12 and shortening the clutch stroke, the elastic pivoting unit 14 needs to be set near the outer periphery of the notch 503 of the stator 502 of the drive motor or set on the periphery of the stator, so that after the second clutch support arm 122 is abutted by the side wall of the notch 503 of the stator 502, a relative pivoting deformation occurs between the second clutch support arm 122 and the first clutch support arm 121, so as to achieve the effect of shortening the secondary stroke space after the clutch arm 12 is deformed.

[0073] In this embodiment, the drain valve structure 200 includes a drain motor 201 and a drain valve 204; the drain valve 204 has a drain channel 242 in its valve housing 241, and a valve core 243 corresponding to opening or closing the drain channel 242 is provided on the valve housing 241; the valve core 243 includes a sealing part 244 and an elastic part 245; the sealing part 244 corresponding to closing or opening the drain channel 242, one end of the elastic part 245 is connected to the sealing part 244, and the other end of the elastic part is connected to the output end of the drain valve 204 via a connecting rope 202; the drain motor 201 has two actions The stroke is achieved by pulling the valve core 243 twice via the pull rope 202. After the drain motor 201 performs the first stroke and pulls the valve core 243 to produce one extension and retraction action, the elastic part 245 independently produces an elastic compression or extension action, while the sealing part 244 does not move and remains closed to the drain channel 242. After the drain motor 201 performs the second stroke and pulls the valve core 243 to produce a second action, the elastic element 142 can no longer produce an elastic compression or extension action, so that the elastic part 245, which has been elastically compressed or extended to its limit, drives the sealing part 244 to open the drain channel 242.

[0074] The specific configuration of the aforementioned drain valve structure 200 can be as follows:

[0075] The drain valve 204 includes a valve housing 241, the interior of which is hollow, forming a drain channel 242. The drain channel 242 is connected in series with the drain pipe of the garment processing equipment, allowing for the controlled discharge of washing water from the water tank 300 of the garment processing equipment. A valve core 243 is mounted on the valve housing 241 of the drain valve 204. The valve core 243 is retractable within the drain channel 242. The valve core 243 is cylindrical and includes a sealing part 244 and an elastic part 245. The sealing part 244 is constructed using a bellows tube, with the telescopic end of the bellows closed and the other opposite end fixedly connected to the inner wall of the valve housing 241, allowing the sealing part 244 to utilize its own corrugations and telescopic movement. The valve core 243 is installed in the drainage channel 242. The elastic part 245 is composed of a spring coaxially disposed in the bellows. One end of the spring is connected to the sealing end of the sealing part 244, and the other end of the spring is connected to the drainage motor 201. The spring is used to slow down the first stroke of the drainage motor 201, so that after the drainage motor 201 generates the first stroke, it only pulls the valve core 243 to move, and the elastic part 245 is stretched by its own elasticity, but it does not drive the sealing part 244 to move, keeping the drainage valve 204 closed. After the drainage motor 201 generates the second stroke, it pulls the valve core 243 to move again, and the stretched elastic part 245 is pulled a second time, driving the sealing part 244 to fold and retract, so as to open the drainage valve 204.

[0076] Furthermore, to ensure the sealing part 244 effectively blocks the drainage channel 242, a return spring 246 can be installed inside the valve housing 241. The return spring 246 is coaxially sleeved on the inner circumference of the sealing part 244, with its two ends abutting against the sealing end of the sealing part 244 and the valve housing 241, respectively, to maintain or drive the sealing part 244 to its initial position of closing the drainage channel 242. Simultaneously, to improve the sealing effect of the sealing part 244, at least one outwardly protruding sealing protrusion is provided at the sealing end of the sealing part 244. This sealing protrusion seals against the inner wall of the valve housing 241, thereby improving sealing performance. In addition, the sealing part 244 is constructed of a material such as rubber that can undergo elastic deformation to further enhance the sealing effect.

[0077] Furthermore, to prevent the spring formed by the elastic part 245 from deflecting, a coaxially arranged limiting sleeve is provided inside the sealing part. The extended end of the limiting sleeve is fixedly connected to the sealing end of the sealing part, and the other end of the limiting sleeve extends out of the valve body and is freely disposed. The limiting sleeve is made of rigid plastic or similar materials. At the same time, the spring forming the elastic part 245 is coaxially disposed in the limiting sleeve, so that the limiting sleeve provides anti-deflection and anti-bending deformation for the spring of the elastic part 245, effectively achieving the control effect of the valve core's stretching and opening / closing action. In addition, the aforementioned return spring 246 can be coaxially sleeved on the outer periphery of the limiting sleeve, and the limiting sleeve can also provide anti-deflection and anti-bending deformation for the return spring 246.

[0078] In this embodiment, one end of the elastic part 245 located outside the valve housing 241 is connected in sequence via a connector 203, a pull rope 202, and a drain motor 201; the connector is connected to the second end of the clutch arm 12, which is pivotally mounted on the housing 3 of the clutch structure 1; the first end of the clutch arm 12 forms a clutch pawl 16 that engages or disengages with the clutch teeth 11 of the deceleration clutch structure 100; a buffer unit 13 is provided on the clutch arm 12 itself or between the clutch arm 12 and the housing 3 of the deceleration clutch structure 100; the specific arrangement can be as follows:

[0079] The clutch arm 12 has a first clutch support arm 121 and a second clutch support arm 122; the first clutch support arm 121 and the second clutch support arm 122 are connected by an elastic pivoting unit 14; the end of the first clutch support arm 121 has a clutch pawl portion 16 that engages or disengages with the clutch teeth 11 of the reduction clutch structure 100; the second clutch support arm 122 is rotatably connected to the mounting plate 4 of the reduction clutch structure 100; the end of the second clutch support arm 122 is provided with a plug-in connection portion 17, which is plugged into and connected to the connector 203. The stroke generated by the drainage motor 201 drives the connector 203 to move, so as to utilize the connector 203 to drive The clutch arm 12 generates a clutch action by rotating around its axis. After the second clutch support arm 122 comes into contact with the stator 502 of the drive motor 5, the elastic pivoting unit 14 is used to make the first clutch support arm 121 rotate around the pivot axis 141 relative to the second clutch support arm 122. This allows the second clutch support arm 122 of the clutch arm 12 to continue to be pulled and rotated by the drainage motor 201. However, the first clutch support arm 121 can overcome the elastic force of the elastic element 142 and rotate around the pivot axis 141, causing the clutch arm 12 to deform. This overcomes the problem that the space at the notch 503 of the stator 502 of the drive motor 5 is insufficient and cannot meet the requirements for the clutch arm 12 to perform a secondary clutch action.

[0080] In this embodiment, the buffer unit 13 includes an elastic pivoting unit 14; the first clutch arm 121 and the second clutch arm 122 are connected via the elastic pivoting unit 14. An elastic element 142 is provided at the pivoting unit to provide a restoring force for the pivoting action between the first clutch arm 121 and the second clutch arm 122. The elastic element 142 can be a torsion spring arranged around the pivoting shaft 141. The torsion spring is fitted around the outer periphery of the pivoting shaft 141, and its two ends are respectively connected to the first clutch arm 121 and the second clutch arm 122. During the relative pivoting process of the first clutch arm 121 and the second clutch arm 122, the torsion spring provides elastic force and a restoring force for the clutch arm 12, ensuring that the clutch arm 12 can be reset to its initial state when the external force is removed, thereby driving the clutch arm 12 to remain in the initial position engaged with the clutch teeth 11.

[0081] In this embodiment, to ensure the effective control of the clutch arm 12 and valve core 243 by the drain motor 201, a certain buffer margin can be set for the stroke of the drain motor 201. That is, the sum of the buffer margins added to the originally designed basic stroke length is used as the corresponding stroke distance of the drain motor 201. Optionally, the buffer margin a1 is added to the basic stroke length L1 for the first stroke, where the length of a1 can be selected as 4mm, and L1+a1 is used as the first stroke length; and the buffer margin a2 is added to the basic stroke length L2 for the second stroke, where the length of a2 can be selected as 1mm, and L2+a2 is used as the second stroke length. Meanwhile, in order to prevent the clutch arm 12 from accidentally opening the drain valve 204 after the first stroke is too long, it is also necessary to ensure that the length of the first stroke L1+a1 is less than the basic stroke length L2 of the second stroke. Preferably, in order to prevent the valve core 243 from being accidentally opened after the first stroke drives the clutch arm 12 to move, the difference between L1+a1 and L2 needs to meet the error gap requirements. The difference needs to be greater than the error gap setting value b1, and the length of b1 can be selected as 2mm.

[0082] This application embodiment also introduces a clothing processing device, which includes: a water tank 300, the water tank 300 being connected to a drain pipe; it also includes the aforementioned clothing processing device with a deceleration clutch drain structure, a drain valve structure 200 being installed on the drain pipe for opening and closing control of the drain pipe; the deceleration clutch structure 100 connects the drive motor 5 to the washing tub and / or impeller in the water tank 300 for disengaging and engaging the drive impeller and / or washing tub to rotate.

[0083] In this embodiment, the garment processing equipment includes washing, drum washing, drainage, and spin-drying modes, etc.; specifically as follows:

[0085] When the tub is being washed, the drain motor 201 is in the first stroke state, the valve core 243 of the drain valve 204 closes the drain pipe, the clutch arm 12 separates from the clutch tooth 11, and the drive motor 5 drives the impeller and the washing tub to rotate together.

[0086] In the drainage mode, the corresponding drain motor 201 is in the second stroke state, the valve core 243 of the drain valve 204 opens the drain pipe, the clutch arm 12 and the clutch tooth 11 are separated, the drive motor does not work, and the impeller and washing tub do not rotate.

[0088] In this embodiment of the application, during the process of the drain motor 201 of the clothing processing equipment switching from the first stroke to the second stroke, the buffer unit 13 of the clutch arm 12 generates a buffering action, which drives the clutch arm 12 to perform a buffering action. The buffering action is used to counteract the pulling action generated by the second stroke of the drain motor 201, so as to avoid excessive movement of the clutch arm 12.

[0089] In this embodiment, during the washing drum operation of the garment processing equipment, the drive motor 5 engages with the impeller and the washing drum via the reduction clutch structure 100, causing the impeller and the washing drum to rotate at the same or different speeds. When the garment processing equipment is in the washing drum operation, the clutch arm 12 and the stator 502 of the drive motor 5 of the reduction clutch structure 100 are in a non-contact or only contact state. At this time, the elastic element 142 of the buffer unit 13 does not undergo elastic deformation and remains in its initial state. Optionally, when the garment processing equipment is in the washing drum operation, the washing drum and the impeller are connected to the rotor 501 of the drive motor 5 via the reduction structure 2, causing the washing drum and the impeller to rotate at the same speed. The rotating impeller and washing drum drive the washing water in the water tank 300, forming a washing drum water flow. This water flow is used to rinse and clean the space between the washing drum and the water tank 300, especially the outer wall of the washing drum and the inner wall of the water tank 300.

[0090] In this embodiment, during the drum-brushing operation of the garment processing equipment, the drive motor engages with the impeller and the washing tub via a reduction clutch structure, causing the impeller and the washing tub to rotate at the same or different speeds. When the garment processing equipment is in the drum-brushing operation, the clutch arm and the stator of the drive motor in the reduction clutch structure are in a non-contact or only contact state. At this time, the elastic element of the buffer unit does not undergo elastic deformation and remains in its initial state. Optionally, when the garment processing equipment is in the drum-brushing operation, the washing tub and the impeller are connected to the rotor of the drive motor via a reduction structure, causing the washing tub and the impeller to rotate at the same speed. The rotating impeller and washing tub drive the washing water in the water tank, forming a drum-brushing water flow. This flow is used to rinse and clean the space between the washing tub and the water tank, especially the outer wall of the washing tub and the inner wall of the water tank.
