A drainage actuator, a cylinder assembly and a washing device

Abstract

The present application provides a drainage actuator, a cylinder assembly and a washing device. The drainage actuator includes a mounting body, a lever assembly, a motor and a transmission mechanism. The lever assembly is slidably connected to the mounting body, and the lever assembly has an extended position and a retracted position. The transmission mechanism includes a power input wheel and a power output wheel that rotate independently of each other. The power input wheel is arranged on the power output shaft of the motor. The power output wheel rotates under the action of the power input wheel and converts its own rotation into the translational motion of the lever assembly to drive the lever assembly to switch between the extended position and the retracted position. Since the power output shaft rotates forward and backward to drive the lever assembly to switch positions, the movement position and stroke of the lever assembly are completely determined by the rotation angle of the power output shaft. The transmission method is reliable, making the movement stroke of the lever assembly reliable and preventing problems such as drainage function failure caused by the failure of components such as springs in the related art, thereby improving the reliability and service life of the drainage actuator.

[0054] The following further describes in detail the embodiments of the present application in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0055] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0056] The embodiment of the present application provides a washing device, including a cylinder assembly 100 and a box body.

[0057] It should be noted that the washing device can be a washing machine, a washing and drying integrated machine, etc., and is not limited herein.

[0058] The cylinder assembly 100 is disposed in the box body. The box body serves as the exterior part of the washing device.

[0059] Please refer to Figure 9 and Figure 10 , the cylinder assembly 100 includes an inner cylinder 10, an outer tub 20, a drain valve assembly 30, and a drain actuator 50.

[0060] The inner cylinder 10 is rotatably disposed in the outer tub 20, and the outer tub 20 provides rotational support for the inner cylinder 10.

[0061] Please refer to Figure 9 and Figure 10 , the outer tub 20 includes a tub body 21 and a rear end cover 22. The front side of the tub body 21 is open, and the rear end cover 22 closes the rear side of the tub body 21.

[0062] It can be understood that the rear end cover 22 can be integrally formed with the rear half of the tub body 21.

[0063] The drain actuator 50 is disposed on the outer tub 20, and exemplarily, is disposed outside the outer tub 20.

[0064] The inner cylinder 10 can hold water and is formed with drain holes. During the process of washing clothes, the washing water is contained in the inner cylinder 10. The inner cylinder 10 can also be referred to as a non-porous inner cylinder, which can avoid the problem of dirt and scale accumulation between the outer tub 20 and the inner cylinder 10 that is prone to occur in the prior art when the outer tub 20 is used to hold water.

[0065] Please refer to Figure 10 and Figure 11 , the drain valve assembly 30 is arranged on the inner cylinder 10, and the inner cylinder 10 rotates together with the drain valve assembly 30. Exemplarily, lifting ribs 40 are arranged in the inner cylinder 10, and the drain valve assembly 30 is arranged in the space within the lifting ribs 40 to prevent clothes from contacting the drain valve assembly 30.

[0066] Please refer to Figure 10 and Figure 11 , the drain valve assembly 30 includes a valve core 31 and a drive rod mechanism 32. The drive rod mechanism 32 has a rotation center line L2. While the drive rod mechanism 32 rotates around the rotation center line L2 by itself, it also revolves around the rotation axis L1 of the inner cylinder 10.

[0067] One end of the drive rod mechanism 32 is drivingly connected to the valve core 31, and the end of the drive rod mechanism 32 away from the valve core 31 is located in the axial gap between the inner cylinder 10 and the outer tub 20 to receive the driving force of the drain pusher 50.

[0068] The valve core 31 is used to seal the drain holes. Specifically, the valve core 31 has a drain position for opening the drain holes and a sealing position for sealing the drain holes. The drive rod mechanism 32 drives the valve core 31 to move between the sealing position for sealing the drain holes (refer to Figure 11 ) and the drain position for opening the drain holes.

[0069] Among them, the movement mode of the valve core 31 can be flipping around the rotation center line L2 of the drive rod mechanism 32, or translating in a direction substantially perpendicular to the rotation center line L2.

[0070] During the washing process, or in other cases where drainage is not required, please refer to Figure 10 and Figure 11 , the valve core 31 is in the sealing position, the valve core 31 seals the drain holes, and the water in the inner cylinder 10 will not be drained, and the inner cylinder 10 acts as a water storage bucket. When drainage or dehydration is required, the drive rod mechanism 32 receives the driving force of the drain pusher 50 and rotates to drive the valve core 31 to switch from the sealing position to the drain position, the drain holes are opened, and the water in the inner cylinder 10 is drained out of the inner cylinder 10 through the drain holes.

[0071] Exemplarily, the water drained from the drain holes enters the outer tub 20, and the outer tub 20 centrally drains the water out of the washing device.

[0072] In one embodiment, please refer to Figure 2 , the rotation axis L1 of the inner cylinder 10 is substantially horizontal. During the rotation of the inner cylinder 10, the drain holes can cyclically pass through the lowest point of the rotation trajectory of the inner cylinder 10, and the water in the inner cylinder 10 can be emptied without dead angles.

[0073] Please refer to Figure 1 , Figure 2 and Figure 3 , the drain diverter 50 includes a mounting body 51, a lever assembly 54, a motor 52 and a transmission mechanism 53.

[0074] The lever assembly 54 is slidably connected to the mounting body 51, that is, the lever assembly 54 can slide relative to the mounting body 51, and the mounting body 51 provides a mounting space and sliding support for the lever assembly 54.

[0075] The lever assembly 54 has an extended position for deflecting the drain valve assembly 30 (please refer to Figure 1 and Figure 11 ) and a retracted position for avoiding the drain valve assembly 30.

[0076] Please refer to Figure 11 , a through hole 22a is provided at the rear side of the outer tub 20, and the movement direction of the lever assembly 54 is substantially parallel to the rotation axis L1 of the inner cylinder 10. The lever assembly 54 can extend into the outer tub 20 through the through hole 22a to interfere with the movement trajectory of the driving rod mechanism 32. Among them, Figure 11 , the lever assembly 54 has just switched to the extended position but has not yet deflected the driving rod assembly 32 to rotate, and the valve core 31 is still in the sealed position.

[0077] During the rotation of the inner cylinder 10 driving the driving rod mechanism 32, when the driving rod mechanism 32 moves to a position where it interferes with the lever assembly 54 (position 11 shown in the figure), since the lever assembly 54 is stationary, under the interference of the lever assembly 54, the driving rod mechanism 32 rotates around its own rotation center line L2, thereby driving the valve core 31 to switch positions.

[0078] As the inner cylinder 10 continues to rotate, the driving rod mechanism 32 disengages from the lever assembly 54, that is, when the driving rod mechanism 32 revolves around the rotation axis L1 to a position where it does not interfere with the lever assembly 54, the valve core 31 still remains in the current position.

[0079] For example, in some embodiments, when the drive rod mechanism 32 revolves around the rotation axis L1 to a position where it does not interfere with the lever component 54, the drive rod mechanism 32 remains in its current position after self-rotation unchanged, and the valve core 31 remains in its current position. In other embodiments, when the drive rod mechanism 32 revolves around the rotation axis L1 to a position where it does not interfere with the lever component 54, the drive rod mechanism 32 rotates idly and resets to its initial position. That is to say, during the idle rotation of the drive rod mechanism 32, it does not drive the valve core 31 to move. Therefore, the valve core 31 can still remain in its current position.

[0080] When the lever component 54 is in the retracted position, the lever component 54 will not interfere with the drive rod mechanism 32 in any case, the drive rod mechanism 32 will not rotate self, and the valve core 31 will not change its position.

[0081] It can be understood that when it is not necessary to move the drive rod mechanism 32, the lever component 54 is in the retracted position.

[0082] The transmission mechanism 53 is used to transmit the power of the power output shaft 521 to the lever component 54.

[0083] Please refer to Figure 2 、 Figure 3 and Figure 6 , the transmission mechanism 53 includes a power input wheel 531 and a power output wheel 532 that rotate independently of each other. That is to say, the power input wheel 531 and the power output wheel 532 do not move as a rigid body, and there is relative movement between the two.

[0084] The power input wheel 531 is arranged on the power output shaft 521 of the motor 52, and the power output shaft 521 drives the power input wheel 531 to rotate synchronously.

[0085] The connection relationship between the power input wheel 531 and the power output shaft 521 is not limited, as long as the torque of the power output shaft 521 can be transmitted to the power input wheel 531. For example, anti-rotation fit can be carried out by means of keys and keyways, or connection can be carried out by means of screws, etc.

[0086] The power output wheel 532 is located at the end of the power transmission path of the transmission mechanism 53. The power output wheel 532 rotates under the action of the power input wheel 531, and converts its own rotation into the translational motion of the lever component 54 to drive the lever component 54 to switch between the extended position and the retracted position.

[0087] Among them, translational motion refers to the motion in which the straight line connecting any two points on the moving object always remains parallel throughout the motion process.

[0088] The power output shaft 521 can rotate forward or reverse selectively to enable the lever component 54 to switch between the extended position and the retracted position.

[0089] It should be noted that the forward rotation and reverse rotation are only used to distinguish the opposite rotation directions of the two, rather than specifying a specific direction.

[0090] The steering of the power output shaft 521 corresponds one-to-one with the position of the shift lever assembly 54. For example, when the power output shaft 521 rotates forward, the motor 52 drives the shift lever assembly 54 from the retracted position to the extended position through the transmission mechanism 53; when the power output shaft 521 rotates in reverse, the motor 52 drives the shift lever assembly 54 from the extended position to the retracted position through the transmission mechanism 53.

[0091] It should be noted that power can be transmitted directly or indirectly between the power output wheel 532 and the power input wheel 531.

[0092] It should be noted that when the shift lever assembly 54 is in the extended position, the inner cylinder 10 can rotate forward to cooperate with the shift lever assembly 54 to open the drain hole, or it can rotate in reverse to cooperate with the shift lever assembly 54 to open the drain hole.

[0093] During the process of the washing equipment washing clothes, the washing water is contained in the inner cylinder 10. During the washing process, or in other occasions where drainage is not required, the valve core 31 seals the drain hole to prevent the water in the inner cylinder 10 from flowing out of the inner cylinder 10. During this process, the shift lever assembly 54 is always in the retracted position, and the rotation direction of the inner cylinder 10 can always rotate forward, or always rotate in reverse, or rotate forward and reverse alternately.

[0094] When the inner cylinder 10 needs to drain water (or dehydrate), the inner cylinder 10 rotates forward, the power output shaft 521 rotates forward, driving the shift lever assembly 54 to move from the retracted position to the extended position. The shift lever assembly 54 forces the driving rod mechanism 32 to rotate forward, driving the valve core 31 to switch from the sealed position to the drain position, and the drain hole is opened. The water in the inner cylinder 10 is discharged from the inner cylinder 10 through the drain hole. Subsequently, the power output shaft 521 rotates in reverse, driving the shift lever assembly 54 to reset from the extended position to the retracted position, and the valve core 31 stably remains in the drain position.

[0095] It should be noted that the shift lever assembly 54 can retract immediately after the inner cylinder 10 rotates one circle, or it can retract after the inner cylinder 10 rotates multiple circles.

[0096] When it is necessary to close the drain hole after drainage, the power output shaft 521 rotates forward, so that the shift lever assembly 54 moves from the retracted position to the extended position again. The inner cylinder 10 rotates in reverse, and the shift lever assembly 54 forces the driving rod mechanism 32 to rotate in reverse, thereby driving the valve core 31 to switch from the drain position to the sealed position. Subsequently, the power output shaft 521 rotates in reverse, driving the shift lever assembly 54 back to the retracted position, and the valve core 31 stably remains in the sealed position.

[0097] In the washing device according to the embodiment of the present application, regardless of the rotation speed of the inner drum 10, as long as the lever assembly 54 extends, the lever assembly 54 forces the drive rod mechanism 32 to rotate, so that the valve core 31 can be switched between the sealing position and the drainage position. The structure is simple, facilitating the drainage of the inner drum 10, and has relatively high reliability.

[0098] It should be noted that the washing device drains water through the drain hole during the washing process or after the washing is completed, and the washing device can also drain water through the drain hole during the dehydration process.

[0099] The drainage toggler 50 according to the embodiment of the present application can be pre-assembled into a pre-assembled whole. On the assembly line of the washing device, the drainage toggler 50 can be directly assembled on the washing device. In this way, the assembly time of the assembly line can be saved, the assembly efficiency can be improved, and the production cost can be reduced.

[0100] In the drainage toggler 50 according to the embodiment of the present application, since the power output shaft 521 does not need linear motion and only needs to rotate, the space and size occupied by the motor 52 are both small; since the movement mode of the lever assembly 54 is translational motion, the space required by the lever assembly 54 is small, and the transmission mechanism 53 only needs to convert the torque into linear displacement and can be compactly arranged between the motor 52 and the lever assembly 54, making the structural arrangement of the drainage toggler 50 relatively compact and facilitating assembly.

[0101] In the related art, the drainage toggler drives the transmission member to move by the traction rope of the tractor. The traction rope and the lever are connected to the opposite ends of the transmission member. The transmission member drives the lever to move under the action of the traction rope, and the moving displacement of the traction rope is the same as the moving displacement of the lever. During the reset or extension process of the lever, the forces on the opposite ends of the transmission member are uneven, which is likely to form a bending moment and cause the transmission member or the lever to get stuck, resulting in a drainage failure of the washing device; in addition, since space needs to be reserved for the movement of the traction rope, the overall size of the drainage toggler is very large, the layout of parts is difficult, and it is difficult to achieve mass production of products; furthermore, the traction rope is a vulnerable part, and after long-term use, problems such as rope breakage and winding failure are likely to occur, resulting in relatively poor overall reliability of the drainage toggler.

[0102] For the drainage toggler 50 according to the embodiment of the present application, the forward and reverse rotations of the power output shaft 521 drive the lever assembly 54 to perform position switching. The movement position and stroke of the lever assembly 54 are completely determined by the rotation angle of the power output shaft 521. The transmission method is reliable, which can ensure the reliable movement stroke of the lever assembly 54 and will not have problems such as the drainage function failure caused by the failure of components such as springs in the related art, improving the reliability and service life of the drainage toggler 50.

[0103] The type of the motor 52 is not limited. It can be a DC motor, an AC motor, or other types of motors.

[0104] Exemplarily, in some embodiments, the motor 52 is a DC motor, and the speed ratio of the power input wheel 531 to the power output wheel 532 is greater than 1. That is to say, the overall transmission ratio of the transmission mechanism 53 is greater than 1.

[0105] In this embodiment, since the transmission ratio is greater than 1, for the same torque output by the power output wheel 532, the power output shaft 521 can output a larger torque of the power output wheel 532 with a smaller torque output. Therefore, the motor 52 can adopt a DC motor with a smaller power and a smaller volume, realizing the miniaturization and compactness of the drainage diverter 50.

[0106] It should be noted that the power input wheel 531 and the power output wheel 532 can directly transmit power or indirectly transmit power.

[0107] Exemplarily, please refer to Figure 2 、 Figure 3 and Figure 6 , the transmission mechanism 53 includes an intermediate transmission wheel member 533. The intermediate transmission wheel member 533 includes a first wheel body 5331 and a second wheel body 5332 that are connected to each other and coaxially arranged. That is to say, the intermediate transmission wheel member 533 forms a rigid whole, and the movement of the intermediate transmission wheel member 533 is a rigid body movement.

[0108] The power input wheel 531 and the power output wheel 532 are located on the same side of the intermediate transmission wheel member 533. The first wheel body 5331 is used to transmit torque to the power input wheel 531, and the second wheel body 5332 is used to transmit torque to the power output wheel 532.

[0109] In this embodiment, since the power input wheel 531 and the power output wheel 532 are located on the same side of the intermediate transmission wheel member 533, the space can be fully utilized, making the structure of the transmission mechanism 53 compact; in addition, secondary transmission is achieved through the intermediate transmission wheel member 533, so that a larger transmission ratio can be obtained while taking into account the compact structure.

[0110] It can be understood that the outer diameter of the first wheel body 5331 is greater than the outer diameter of the second wheel body 5332, the outer diameter of the power input wheel 531 is less than the outer diameter of the first wheel body 5331, and the outer diameter of the second wheel body 5332 is less than the outer diameter of the power output wheel 532, which is beneficial to realizing that the speed ratio of the power input wheel 531 to the power output wheel 532 is greater than 1.

[0111] The transmission method of the transmission mechanism 53 is not limited. For example, a chain transmission method, a gear transmission method, a belt transmission method, etc. can be adopted.

[0112] Exemplarily, in an embodiment using a belt drive, both the power input wheel 531 and the power output wheel 532 are pulleys, and the power input wheel 531 and the power output wheel 532 can be directly driven by a belt, and this transmission method is a single-stage transmission; other intermediate pulleys can also be set on the power transmission path between the power input wheel 531 and the power output wheel 532 to achieve multi-stage transmission.

[0113] Exemplarily, in an embodiment using a chain transmission, both the power input wheel 531 and the power output wheel 532 are sprockets, and the power input wheel 531 and the power output wheel 532 can be directly transmitted by the chain, and this transmission method is a single-stage transmission; other intermediate sprockets can also be set on the power transmission path between the power input wheel 531 and the power output wheel 532 to achieve multi-stage transmission.

[0114] For example, in the embodiment of the present application, the transmission mechanism 53 adopts gear transmission to transmit power as an example, the power input wheel 531 and the power output wheel 532 are both gears, and the power input wheel 531 and the power output wheel 532 are directly or indirectly gear-engaged, that is, the power input wheel 531 and the power output wheel 532 can be directly meshed, which is a primary transmission; the power input wheel 531 and the power output wheel 532 can also be indirectly transmitted through other gears, which is a multi-stage transmission. In this embodiment, the gear transmission is stable, reliable, efficient, long-life, and compact.

[0115] Exemplarily, the axis of the power output shaft 521 is perpendicular to the movement direction of the lever assembly 54. The movement direction of the lever assembly 54 is parallel to the rotation centerline L2 of the driving rod mechanism 32. For example, the power output shaft 521 is arranged along the radial direction of the inner cylinder 10, and the lever assembly 54 moves along the axial direction of the inner cylinder 10. In this way, the installation space required for the drainage toggle 50 can be reduced, and the motor 52 can be arranged along the radial direction of the rear end, making full use of the space between the rear end cover and the box body.

[0116] The specific structure of the lever assembly 54 is not limited.

[0117] For example, see Figure 5 The lever assembly 54 includes a lever 541 and a sliding seat 542 which are connected to each other.

[0118] See also Figure 2 and Figure 6 The sliding seat 542 is provided with a sliding groove 542a, and an eccentric boss 5321 is provided on the side of the power output wheel 532 facing the sliding seat 542. The eccentric boss 5321 extends into the sliding groove 542a and drives the sliding seat 542 to swing linearly during its rotation around the center of the power output wheel 532.

[0119] The structural form of the lever 541 and the sliding seat 542 allows the lever 541 to be thinner and the sliding seat 542 to be larger, which facilitates the design of the slide groove 542a.

[0120] The rotation trajectory of the eccentric boss 5321 is an arc around the center of the power output wheel 532, and the rotation trajectory of the eccentric boss 5321 has a displacement change in the linear motion direction of the lever assembly 54. Therefore, through the cooperation between the eccentric boss 5321 and the slide groove 542a, the rotation of the eccentric boss 5321 is converted into the linear motion of the lever assembly 54, and the rotation angle of the eccentric boss 5321 around the axis of the power output shaft 521 corresponds one-to-one to the position of the lever assembly 54.

[0121] The lever 541 and the sliding seat 542 may be made of the same material or different materials.

[0122] For example, the lever 541 is made of metal material, so that the lever 541 has sufficient structural strength and rigidity to withstand the torque when the driving rod mechanism 32 is moved. The sliding seat 542 is made of plastic material to reduce the cost.

[0123] The specific connection method of the sliding seat 542 and the lever 541 is not limited, as long as the two can form a rigid body and move together, for example, by screw connection, clamping connection, etc.

[0124] For some examples, see Figure 5 A rib 5411 is provided on the circumferential surface of the lever 541, and a groove 542b is provided on the sliding seat 542, and the rib 5411 is embedded in the groove 542b. In this way, the rib 5411 can bear part of the shear force to prevent the lever 541 from rotating.

[0125] For example, see Figure 2 , Figure 3 and Figure 5 , one of the mounting body 51 and the lever assembly 54 is provided with a guide rail 54a extending along the movement direction of the lever assembly 54, see Figure 4 The other one is provided with a guide groove 511b extending along the movement direction of the lever assembly 54, and the guide rail 54a and the guide groove 511b are slidably matched. In this way, the linear reciprocating motion of the lever assembly 54 can be well guided, and the risk of the lever assembly 54 being stuck can be reduced.

[0126] The number of guide rails 54a is not limited, and may be one or more. The number of guide grooves 511b is not limited, and may be one or more.

[0127] It should be noted that in the embodiment where the guide rail 54a is provided on the lever assembly 54 and the guide groove 511b is provided on the mounting body 51, all the guide rails 54a can be provided on the lever 541; or all the guide rails 54a can also be provided on the sliding seat 542; or a part of the guide rails 54a can be provided on the lever 541 and the other part of the guide rails 54a can be provided on the sliding seat 542.

[0128] Exemplarily, the mounting body 51 has a packaging cavity 51a (refer to Figure 8 ) and a mounting port 511a (refer to Figure 1 and Figure 8 ). The sliding seat 542, the motor 52 and the transmission mechanism 53 are all arranged in the packaging cavity 51a, and the lever 541 extends out from the mounting port 511a. In this embodiment, the mounting body 51 surrounds the sliding seat 542, the motor 52 and the transmission mechanism 53, and the drainage diverter 50 can be transported and assembled as an independent component. The mounting body 51 prevents other components from rubbing against the components inside, improving reliability.

[0129] It should be noted that the packaging cavity 51a means surrounding in terms of space, not specifically referring to gas tightness. That is to say, the air flow in the packaging cavity 51a can exchange air flow with the outside or not.

[0130] Exemplarily, please refer to Figure 1 , Figure 2 and Figure 3 , the mounting body 51 includes a bottom shell 511 and a cover body 512. The bottom shell 511 is open on the first side along the moving direction of the lever assembly 54, and the cover body 512 is covered on the open part of the bottom shell 511 to jointly define the packaging cavity 51a. The side wall of the second side of the bottom shell 511 along the moving direction of the lever assembly 54 is provided with a mounting port 511a, and the lever 541 extends out from the mounting port 511a.

[0131] During assembly, the moving seat, the motor 52 and the transmission mechanism 53 are placed into the bottom shell 511 from the open part of the bottom shell 511, and then the cover body 512 is installed.

[0132] The connection method between the cover body 512 and the bottom shell 511 is not limited.

[0133] In some embodiments, the cover body 512 and the bottom shell 511 adopt a non-detachable connection method, such as welding, fusion welding, etc. In other embodiments, the cover body 512 and the bottom shell 511 adopt a detachable connection method, such as screw connection, snap connection, etc., which is convenient for after-sales maintenance.

[0134] Exemplarily, please refer to Figure 1 , Figure 2 and Figure 3, multiple elastic hooks 5121 are provided on the cover body 512, and a convex buckle 5111 is provided on the outer surface of the bottom shell 511. The elastic hooks 5121 are buckled on the convex buckle 5111. In this way, no special tool is required during the assembly process, which facilitates quick assembly and saves assembly time.

[0135] Exemplarily, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 , the installation main body 51 includes a support plate 513 disposed between the transmission mechanism 53 and the sliding seat 542. Please refer to Figure 4 , the bottom shell 511 is provided with a limit slot 511d and a first notch. The support plate 513 is inserted from the open part of the bottom shell 511 and constrained in the limit slot 511d. The limit slot 511d can prevent the support plate 513 from twisting and prevent the support plate 513 from moving around in the bottom shell 511.

[0136] Please refer to Figure 2 , the support plate 513 is provided with a shaft hole 513a. The axial first end of the power output wheel 532 is inserted into the shaft hole 513a. The first notch opens towards the cover body 512 side. The axial second end of the power output wheel 532 is snapped into the first notch along the extending direction of the lever assembly 54.

[0137] During the assembly process, the first end of the power output wheel 532 can be axially inserted into the shaft hole 513a first, and then the support plate 513 and the power output wheel 532 are placed into the bottom shell 511 together. During the placement process, the axial second end of the power output wheel 532 is inserted into the first notch. In this way, axial two-way support for the power output wheel 532 can be achieved.

[0138] After the cover body 512 is assembled on the bottom shell 511, the inner part of the cover body 512 abuts against the support plate 513 to position the support plate 513. In addition, the inner part of the cover body 512 can also be inserted into the first notch to position the axial first end of the power output wheel 532.

[0139] It can be understood that in the embodiment provided with the intermediate transmission wheel member 533, the number of the shaft holes 513a is two. The axial second end of the power output wheel 532 is inserted into one of the shaft holes 513a, and the axial second end of the intermediate transmission wheel member 533 is inserted into the other shaft hole 513a; the bottom shell 511 is further provided with a second notch, and the second notch opens towards the cover body 512 side. The axial first end of the intermediate transmission wheel member 533 is snapped into the second notch along the extending direction of the lever assembly 54.

[0140] Exemplarily, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7, the drain actuator 50 includes an electrical plug 55 which is configured with a plurality of pins 551 for electrically connecting with an external power cord to achieve electrical signal transmission.

[0141] It can be understood that the motor 52 and other electrically-powered components on the drain actuator 50 obtain power through the electrical plug 55 and transmit electrical signals outward.

[0142] Please refer to Figure 4 , on the side wall of the bottom shell 511 away from the motor 52, there is a through groove 511h; each pin 551 extends along the axial direction of the power output shaft 521 and passes through the through groove 511h.

[0143] Exemplarily, the drain actuator 50 includes a position detection device for detecting the position of the lever assembly 54. The position detection device is electrically connected to the above-mentioned electrical plug 55 and feeds back displacement signals outward through the pins 551.

[0144] The electrical plug 55 is arranged adjacent to the position detection device, facilitating cable layout.

[0145] The specific type of the position detection device is not limited. For example, it can be a travel switch.

[0146] Exemplarily, the drain actuator 50 is installed on the rear side of the rear end cover 22. Please refer to Figure 9 , in the plane projection perpendicular to the rotation axis of the inner cylinder 10, the projection of the drain actuator 50 is located within the projection of the outer tub 20. In this way, the drain actuator 50 does not affect the radial dimension of the outer tub 20 and does not affect the assembly of the components between the outer tub 20 and the cabinet.

[0147] For the convenience of installing the drain actuator 50 and the rear end cover 22, exemplarily, please refer to Figure 1 、 Figure 3 , a plurality of ear plates 5112 are arranged around the outside of the bottom shell 511. The plate surfaces of the ear plates 5112 face the rear end cover 22, and screws pass through the ear plates 5112 from the rear to the front and are screwed into the rear end cover 22.

[0148] The washing device includes a control device and a driving motor 52.

[0149] The driving motor 52 is used to drive the inner cylinder 10 to rotate forward or backward selectively. It can be understood that the driving motor 52 can directly drive the inner cylinder 10 to rotate or indirectly drive the inner cylinder 10 to rotate through transmission parts such as belts.

[0150] The control device communicates with the driving motor 52 and the motor 52 to control the rotation timing and rotation direction of the motor 52 and the driving motor 52. In this way, the drainage control of the inner cylinder 10 is achieved through the combined cooperation of the rotation direction of the inner cylinder 10 and the expansion and contraction of the lever assembly 54.
