[0041] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] In the description of the embodiments of the present application, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the embodiments of the present application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0043] An embodiment of the present application provides a clothing processing device, including a drum device 100 and a box body.

[0044] It should be noted that the clothing processing device can be a washing machine, a washer-dryer, etc., and there is no limitation here.

[0045] The drum unit 100 is arranged in the box body. The box body serves as the appearance part of the clothes processing device.

[0046] See also Figure 1 and Figure 2 The cylinder assembly 100 includes an inner cylinder 10, an outer barrel 20, a drain valve assembly 30 and a drain driving device 50.

[0047] The inner barrel 10 is rotatably disposed in the outer barrel 20 , and the outer barrel 20 provides support for the inner barrel 10 .

[0048] See also Figures 1 to 4 The outer barrel 20 includes a barrel body 21 and a rear end cover 22 . The front side of the barrel body 21 is open, and the rear end cover 22 closes the rear side of the barrel body 21 .

[0049] The drainage driving device 50 is disposed on the outer tub 20 , illustratively, outside the outer tub 20 .

[0050] The inner drum 10 is capable of holding water and has drainage holes formed therein. During the laundry washing process, the washing water is held in the inner drum 10, which can also be referred to as a non-porous inner drum. This avoids the problem of prior art where water is held in an outer drum, which can easily trap dirt and grime between the outer and inner drums.

[0051] See also Figure 2 、 Figure 3 and Figure 4 The drain valve assembly 30 is arranged on the inner drum 10, and the inner drum 10 rotates with the drain valve assembly 30. For example, a lifting rib 40 is provided in the inner drum 10, and the drain valve assembly 30 is arranged in the space within the lifting rib 40 to prevent the clothes from contacting the drain valve assembly 30.

[0052] See also Figure 2 、 Figure 3 and Figure 4 The drain valve assembly 30 includes a valve core 31 and a transmission rod mechanism 32. The transmission rod mechanism 32 has a rotation center line L2. The transmission rod mechanism 32 rotates around the rotation center line L2 and also revolves around the rotation axis L1 of the inner cylinder 10.

[0053] One end of the transmission rod mechanism 32 is drivingly connected to the valve core 31, and the end of the transmission rod mechanism 32 away from the valve core 31 is located between the inner cylinder 10 and the outer barrel 20 to receive the driving force of the drainage driving device 50.

[0054] The valve core 31 is used to seal the drain hole. Specifically, the valve core 31 has a drain position for opening the drain hole and a sealing position for sealing the drain hole. The transmission rod mechanism 32 drives the valve core 31 to move between the sealing position for sealing the drain hole and the drain position for opening the drain hole.

[0055] The movement of the valve core 31 may be flipping around the rotation center line L2 of the transmission rod mechanism 32 , or may be moving in a translational manner in a direction substantially perpendicular to the rotation center line L2 .

[0056] During the washing process, or other situations where drainage is not required, refer to Figure 4 When the valve core 31 is in the sealing position, it seals the drain hole, preventing water from draining out of the inner drum 10, and the inner drum 10 functions as a water storage tub. When drainage or dehydration is required, the transmission rod mechanism 32 receives the driving force of the drainage drive device 50 and rotates, driving the valve core 31 from the sealing position to the drain position, opening the drain hole, and allowing the water in the inner drum 10 to drain out of the inner drum 10 through the drain hole.

[0057] Illustratively, the water discharged from the drainage hole enters the outer tub 20 , and the outer tub 20 collectively drains the water out of the clothes treating apparatus.

[0058] The drainage hole can be provided at any suitable position of the inner drum 10 , as long as the water in the inner drum 10 can be discharged through the drainage hole.

[0059] For example, the drainage holes are formed in the rotational circumference of the inner drum 10 so that the inner drum 10 can throw water out of the drainage holes by centrifugal force during the dehydration process.

[0060] In one embodiment of this application, please refer to Figure 2 The rotation axis of the inner drum 10 is roughly in the horizontal direction. During the rotation of the inner drum 10, the drainage hole can circulate through the lowest point of the rotation trajectory of the inner drum 10, and the water in the inner drum 10 can be drained without dead angles.

[0061] See also Figures 5 to 8 The drainage driving device 50 includes a mounting seat 51 , a lever assembly 54 , a motor assembly 52 and a reversing member 53 .

[0062] The lever assembly 54 is slidably connected to the mounting seat 51, that is, the lever assembly 54 can slide relative to the mounting seat 51. The lever assembly 54 has an extended position for shifting the drain valve assembly 30 (see Figure 3 、 Figure 5 and Figure 7 ) and avoid the retracted position of the drain valve assembly 30 (see Figure 4 and Figure 8 ).

[0063] See also Figure 3 The rear side of the outer tub 20 is provided with a through hole 22a, and the movement direction of the lever assembly 54 is substantially parallel to the rotation axis L1 of the inner tub 10. When the lever assembly 54 is extended, it can extend into the outer tub 20 through the through hole 22a, thereby interfering with the movement trajectory of the transmission rod mechanism 32.

[0064] During the process of the inner cylinder 10 driving the transmission rod mechanism 32 to rotate, when the transmission rod mechanism 32 moves to a position where it interferes with the shifting rod assembly 54 ( Figure 3 As shown in the position, since the lever assembly 54 is stationary, under the interference of the lever assembly 54, the transmission rod mechanism 32 rotates around its own rotation center line L2, thereby driving the valve core 31 to switch positions.

[0065] As the inner cylinder 10 continues to rotate, the transmission rod mechanism 32 is separated from the shifting rod assembly 54 , that is, when the transmission rod mechanism 32 orbits around the axis L1 to a position where it does not interfere with the shifting rod assembly 54 , the valve core 31 still maintains the current position.

[0066] For example, in some embodiments, when the transmission rod mechanism 32 orbits about the axis L1 to a position where it does not interfere with the shift lever assembly 54, the transmission rod mechanism 32 remains in its rotated position, and the valve core 31 remains in its current position. In other embodiments, when the transmission rod mechanism 32 orbits about the axis L1 to a position where it does not interfere with the shift lever assembly 54, the transmission rod mechanism 32 idles and returns to its initial position. In other words, during the idle rotation of the transmission rod mechanism 32, the valve core 31 does not move, and therefore the valve core 31 remains in its current position.

[0067] See also Figure 4 When the lever assembly 54 is in the retracted position, the lever assembly 54 will not interfere with the transmission rod mechanism 32 in any way, the transmission rod mechanism 32 will not rotate, and the valve core 31 will not change position.

[0068] The reversing member 53 is used to convert the rotation of the power output shaft 521 of the motor assembly 52 into the translation of the lever assembly 54, thereby at least driving the lever assembly 54 from the retracted position to the extended position. In other words, the lever assembly 54 is in the retracted position by default. When the power output shaft 521 rotates (for example, either forward or reverse), the power output shaft 521 drives the lever assembly 54 from the retracted position to the extended position.

[0069] Among them, translation means that the straight line connecting any two points on the moving object always maintains parallel motion during the entire movement process.

[0070] It should be noted that the internal structure of the motor assembly 52 is not limited. The motor assembly 52 can be purchased directly from the market as a whole, as long as its power output shaft 521 can output the corresponding torque. For example, the power output shaft 521 can be directly fixedly connected to the rotor of the motor assembly 52, or it can be in relative motion with the rotor and receive the rotor's torque through a gear transmission, etc., without limitation herein.

[0071] It is understandable that when the transmission rod mechanism 32 does not need to be moved, the lever assembly 54 is reset to the retracted position. It should be noted that the terms forward and reverse are only used to distinguish between opposite rotation directions, and do not refer to specific directions.

[0072] For example, when the power output shaft 521 rotates forward, the lever assembly 54 can be switched from the retracted position to the extended position. In other embodiments, when the power output shaft 521 rotates backward, the lever assembly 54 can be switched from the retracted position to the extended position. For ease of description, in the embodiments of the present application, the example of switching the lever assembly 54 from the retracted position to the extended position when the power output shaft 521 rotates forward is used for description. It should be noted that when the lever assembly 54 is in the extended position, the inner cylinder 10 can rotate forward to cooperate with the lever assembly 54 to open the drain hole, or it can rotate backward to cooperate with the lever assembly 54 to open the drain hole.

[0073] For the convenience of description, the inner drum 10 rotates forward to cooperate with the lever assembly 54 to open the drain hole.

[0074] During the laundry processing process, the washing water is contained in the inner drum 10. During the washing process, or in other situations where drainage is not required, the valve core 31 seals the drain port to prevent the water in the inner drum 10 from flowing out of the inner drum 10. During this process, the lever assembly 54 is always in the retracted position, and the rotation direction of the inner drum 10 can be always forward, always reverse, or alternately forward and reverse.

[0075] When the inner drum 10 needs to be drained (or dehydrated), the inner drum 10 rotates forward, and the power output shaft 521 rotates forward, driving the lever assembly 54 from the retracted position to the extended position. The lever assembly 54 forces the transmission rod mechanism 32 to rotate forward, driving the valve core 31 from the sealing position to the drain position, opening the drain port, and the water in the inner drum 10 is discharged from the inner drum 10 through the drain port. Subsequently, the lever assembly 54 returns from the extended position to the retracted position, and the valve core 31 is stably in the drain position.

[0076] It should be noted that the lever assembly 54 can be retracted immediately after the inner cylinder rotates one circle, or it can be retracted after the inner cylinder rotates multiple circles.

[0077] When the drain hole needs to be closed after draining, the power output shaft 521 rotates forward, causing the lever assembly 54 to move from the retracted position to the extended position again. The inner cylinder 10 rotates reversely, and the lever assembly 54 forces the transmission rod mechanism 32 to reverse, thereby driving the valve core 31 from the drain position to the sealing position. Subsequently, the lever assembly 54 returns to the retracted position, and the valve core 31 is stably in the sealing position.

[0078] In the clothing processing device of the embodiment of the present application, no matter what the rotation speed of the inner drum 10 is, as long as the lever assembly 54 is extended, the lever assembly 54 forces the transmission 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, the drainage of the inner drum 10 is convenient, and the reliability is high.

[0079] It should be noted that the clothes processing device drains water through the drain hole during the washing process or after washing, and the clothes processing device can also drain water through the drain hole during the dehydration process.

[0080] The drainage drive device 50 of the embodiment of the present application can be assembled into a pre-assembled whole in advance. On the assembly line of the clothing processing equipment, the drainage drive device 50 can be directly assembled on the clothing processing equipment. In this way, the assembly line time can be saved, the assembly efficiency can be improved, and the production cost can be reduced.

[0081] In the related art, a drainage drive device uses a traction rope from a traction device to move a transmission member. The traction rope and a lever are connected at opposite ends of the transmission member. The transmission member, under the action of the traction rope, drives the lever to move, and the displacement of the traction rope is similar to the movement of the lever. During the reset or extension of the lever, the opposite ends of the transmission member are subjected to uneven force, which can easily form a bending moment and cause the transmission member or the lever to become stuck, resulting in drainage failure in the clothing processing device. In addition, the need to reserve space for the traction rope makes the overall size of the drainage drive device large, making component layout difficult and hindering mass production. Furthermore, the traction rope is a consumable part and is prone to breakage and winding failure after long-term use, resulting in poor overall reliability of the drainage drive device.

[0082] In the drainage drive device 50 of the embodiment of the present application, the installation space required for the motor assembly 52 is relatively small. Since the movement mode of the lever assembly 54 is linear motion, the space required for the lever assembly 54 is also relatively small. The reversing member only needs to convert the torque into linear displacement and can be compactly arranged between the motor assembly 52 and the lever assembly 54, so that the structural arrangement of the drainage drive device 50 is relatively compact and easy to assemble. In addition, the transmission method between the power output shaft 521, the reversing member 53, and the lever assembly 54 is reliable, there is no soft connection such as a traction rope, and there are almost no wearing parts, which can extend the service life of the drainage drive device 50.

[0083] The power source for resetting the lever assembly 54 is not limited.

[0084] For example, in some embodiments, the lever assembly 54 can be reset to the retracted position under the action of an elastic reset member. In this embodiment, the power output shaft 521 only drives the lever assembly 54 to move linearly toward the transmission rod mechanism 32. That is, the power output shaft 521 only applies a force to the lever assembly 54 in the direction from the retracted position to the extended position, and does not apply a force in the opposite direction to the lever assembly 54. That is, when the power output shaft 521 is reversed, no driving force is applied to the lever assembly 54, and the lever assembly 54 is reset to the retracted position under the action of the elastic reset member.

[0085] In other embodiments, the power output shaft 521 drives the lever assembly 54 to move linearly back and forth via the reversing member 53, thereby switching the lever assembly 54 between the extended position and the retracted position. In this embodiment, the position of the lever assembly 54 at any moment is determined by the rotation angle of the power output shaft 521. In other words, the power output shaft 521 drives the lever assembly 54 from the retracted position to the extended position, and also drives the lever assembly 54 from the extended position to the retracted position.

[0086] In this embodiment, the movement position and stroke of the lever assembly 54 are completely determined by the rotation angle of the power output shaft 521, which can ensure that the movement stroke of the lever assembly 54 is reliable and will not cause the problem of drainage function failure due to failure of components such as springs in related technologies.

[0087] In some embodiments, the power output shaft 521 can be rotated in the same direction to switch the lever assembly 54 between the extended position and the retracted position. For example, a forward rotation of 180° switches the lever assembly 54 from the retracted position to the extended position, and another forward rotation of 180° switches the lever assembly 54 from the extended position to the retracted position.

[0088] In other embodiments, the power output shaft 521 can be rotated forward and reversely to switch the lever assembly 54 between the extended position and the retracted position. For example, the power output shaft 521 rotates forward by a certain angle to drive the lever assembly 54 from the retracted position to the extended position via the reversing member. Thereafter, the power output shaft 521 rotates backward by a certain angle to drive the lever assembly 54 from the extended position to the retracted position via the reversing member.

[0089] It should be noted that the motor assembly 52 is equipped with an angle detection function and automatically forms a closed-loop control. For example, when the power output shaft 521 rotates forward (or reverse) through a preset angle, such as 180°, the motor assembly 52 automatically stops the power output shaft 521, thereby enabling relatively accurate control of the position of the shift lever assembly 54.

[0090] For example, see Figure 3 and Figure 4 The axis L3 of the power output shaft 521 is perpendicular to the direction of movement of the lever assembly 54, wherein the direction of movement of the lever assembly 54 is parallel to the rotation centerline L2 of the transmission 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.

[0091] In this embodiment, since the power output shaft 521 does not need to move in a linear manner but only needs to rotate, the space and size occupied by the motor assembly 52 are relatively small, and the axial size of the lever assembly 54 only needs to meet the movement stroke of the lever assembly 54 itself. In this way, the installation space required for the drainage drive device 50 can be reduced.

[0092] For example, the commutator 53 is a rigid body. A rigid body means that during motion and after being subjected to force, the degree of deformation in shape and size is extremely small relative to the geometric dimensions of the commutator 53 itself, and the relative positions of various points within it remain essentially unchanged. This deformation can be ignored when studying the motion of the commutator 53.

[0093] In this embodiment, the reversing member 53 is a rigid body with only one component, which can effectively and reliably transmit the force, reduce assembly time and improve assembly efficiency; the number of components is small, which is easy to manufacture, reduces production costs, and is easy to promote and use.

[0094] The specific structure and shape of the reversing member 53 are not limited, as long as it can convert the rotation of the power output shaft 521 into the linear motion of the shifting lever assembly 54 .

[0095] For example, see Figure 7 and Figure 8 The reversing member 53 includes a rotating disk 531 and a cam 532 connected to each other. The rotating disk 531 is fixedly engaged with the power output shaft 521, that is, the power output shaft 521 transmits torque to the rotating disk 531. The rotating disk 531 and the power output shaft 521 are coaxially arranged, and the rotation center of the rotating disk 531 is located on the axis L3 of the power output shaft 521.

[0096] There is no limitation on the anti-rotation cooperation mode between the power output shaft 521 and the turntable 531. For example, torque transmission can be achieved through keyways and keys, or through screw connections to achieve fixed connection and transmit torque.

[0097] The protruding shaft 532 is eccentrically disposed on one axial side of the turntable 531 , specifically, on the side of the turntable 531 away from the motor assembly 52 , and the protruding shaft 532 is eccentrically disposed with respect to the axis of the power output shaft 521 .

[0098] See also Figure 7 and Figure 8The lever assembly 54 is provided with a slide groove 542a, in which the protruding shaft 532 is disposed and slidable. The extension direction of the slide groove 542a, the movement direction of the lever assembly 54, and the axis L3 of the power output shaft 521 are orthogonal to each other, forming a three-dimensional rectangular coordinate system. Specifically, the slide groove 542a extends generally in a straight line along the left-right direction of the laundry processing device, the lever assembly 54 moves generally in a straight line along the front-back direction of the laundry processing device, and the power output shaft 521 is arranged generally in the vertical direction of the laundry processing device.

[0099] The rotation trajectory of the convex shaft 532 is an arc around the axis L3, and the rotation trajectory of the convex shaft 532 has a displacement change in the linear motion direction of the shift lever assembly 54. Therefore, through the cooperation between the convex shaft 532 and the slide groove 542a, the rotation of the convex shaft 532 is converted into the linear motion of the shift lever assembly 54, and the rotation angle of the convex shaft 532 around the axis of the power output shaft 521 corresponds one-to-one to the position of the shift lever assembly 54.

[0100] In this embodiment, the structure of the switching member 53 is relatively simple, and the axial dimensions of the turntable 531 and the cam 532 are relatively small. Therefore, the switching member 53 does not need to have a large rigidity and structural strength. The switching member 53 is made of plastic material and can also meet the rigidity and structural strength requirements. In this way, the cost can be greatly reduced.

[0101] For example, the motor assembly 52 may be a common motor assembly 52 on the market without customization.

[0102] The specific structure of the lever assembly 54 is not limited.

[0103] For example, see Figure 7 and Figure 8 The lever assembly 54 includes a lever 541 and a base 542 connected to each other, and the rear end of the lever 541 is connected to the base 542.

[0104] The sliding groove 542 a is provided on the base 542 , and the protruding shaft 532 is inserted into the sliding groove 542 a from one side of the base 542 .

[0105] The structural form of the lever 541 and the base 542 allows the lever 541 to be thinner and the base 542 to be larger, which facilitates the design of the slide groove 542a.

[0106] The shift lever assembly 54 is slidably engaged with the mounting base 51 via the base 542 .

[0107] The lever 541 and the base 542 may be made of the same material or different materials.

[0108] For example, the lever 541 is made of metal so that the lever 541 has sufficient structural strength and rigidity to withstand the torque when the transmission rod mechanism 32 is moved. The base 542 is made of plastic to reduce costs.

[0109] For example, see Figure 7 and Figure 8 The mounting seat 51 is provided with a mounting space 51 a , and a mounting opening 51 b communicating with the mounting space 51 a is provided on the front side of the mounting seat 51 ; the shifting rod 541 can extend from the mounting opening 51 b .

[0110] The reversing member 53 and the base 542 are disposed in the installation space 51a. The mounting seat 51 slidably constrains the base 542 in the installation space 51a. In other words, the cooperation between the base 542 and the mounting seat 51 can better position the sliding of the shifting rod 541.

[0111] It should be noted that in some embodiments, when the lever assembly 54 is in the retracted position, the lever 541 can be completely accommodated in the installation space 51a. In other embodiments, regardless of whether the lever assembly 54 is in the extended or retracted position, the front end of the lever 541 always extends from the installation opening 51b to the outside of the installation space 51a.

[0112] Exemplarily, the mounting base 51 is an integrally formed structure, for example, an integrally injection-molded or vacuum-molded plastic part. In this way, the number of parts of the mounting base 51 can be reduced, and the assembly process can be reduced, saving assembly time.

[0113] The motor assembly 52 and the mounting seat 51 are arranged in the up-down direction. For example, the motor assembly 52 is located above the mounting seat 51 , or the mounting seat 51 is located above the motor assembly 52 .

[0114] For example, see Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the mounting base 51 is disposed below the motor assembly 52. ​​In this case, please refer to Figure 2 、 Figure 3 and Figure 4 , the motor housing 522 of the motor assembly 52 can be installed on the barrel body 21, the motor housing 522 and the barrel body 21 have at least one force connection point, and the barrel body bears the weight of the motor assembly 52. ​​The mounting base 51 is installed to the rear end cover 22, and the mounting base 51 and the rear end cover 22 have at least one force connection point. In this embodiment, the weight of the motor assembly 52 is borne by the barrel body 21, which can reduce the shear force on the connecting parts such as screws at the connection; in addition, even if the water in the outer barrel 20 seeps out through the through hole 22a, since the position of the motor assembly 52 is higher than that of the mounting base 51, the water will not flow down to the motor assembly, thereby improving the reliability of the drainage drive device.

[0115] The motor assembly 52 can be installed at any height of the circumference of the barrel body 21. For example, the motor assembly 52 is installed on the top of the barrel body 21 to avoid water leakage and affect the normal operation of the motor assembly 52.

[0116] For some examples, see Figure 5 The outer surface of the motor housing 522 is provided with an ear plate 5221, which is provided with a through hole 5221a. The barrel body 21 is provided with a screw column, and the screw passes through the through hole 5221a and is screwed into the screw column. In other embodiments, the motor housing 522 is provided with a buckle, and the barrel body 21 is provided with a buckle structure, and the buckle is buckled on the buckle structure.

[0117] For example, see Figure 5 and Figure 6 The mounting base 51 is provided with connecting ears 511 on the left and right opposite sides, and the connecting ears 511 have connecting holes 511a. The rear end cover 22 is provided with mounting columns, and screws pass through the connecting holes 511a and are screwed into the mounting holes 22a.

[0118] For example, see Figure 7 and Figure 8 In the embodiment where the mounting base 51 is positioned below the motor assembly 52, the top side of the mounting space 51a is open, and the motor assembly 52 covers the opening on the top side of the mounting space 51a. During assembly, the lever assembly 54 is assembled as a single unit and then mounted on the mounting base 51. The reversing member 53 can be pre-installed on the mounting base 51 or mounted on the power output shaft 521. The mounting base 51 is then assembled on the motor housing 522 from the bottom side of the motor assembly 52. ​​This reduces the weight of the mounting base 51 and simplifies its structure, while also facilitating assembly.

[0119] For example, in an embodiment where the mounting base 51 is disposed below the motor assembly 52 and the top side of the mounting space 51a is open, the commutator 53 is fixedly connected to the power output shaft 521 and suspended below the power output shaft 521. In other words, the weight of the commutator 53 is borne by the power output shaft 521, rather than by the mounting base 51. This reduces the chance of the cam 532 getting stuck and reduces the rotational resistance of the power output shaft 521. During assembly, the commutator 53 is first mounted on the power output shaft 521. The mounting base 51, equipped with the shift lever assembly 54, is then pushed from the bottom side toward the top side of the motor housing 522, ensuring that the cam 532 is inserted into the slot 542a. The mounting base 51 is then assembled on the motor housing 522.

[0120] For example, see Figure 7 and Figure 8The turntable 531 is provided with a through hole 53a, and the screw passes through the through hole 53a from bottom to top and is screwed into the power output shaft 521 from the shaft end surface of the power output shaft 521.

[0121] The connection method between the mounting base 51 and the motor housing 522 is not limited, for example, screw connection, welding, clamping, etc. It is understandable that the mounting base 51 can also be integrally formed with part of the structure of the motor housing 522 when the assembly requirements are met.

[0122] For example, see Figure 6 、 Figure 7 and Figure 8 The rear side of the mounting space 51a is open, and the base 542 and the reversing member 53 are exposed to the outside view of the mounting base 51. In this way, the lever assembly 54 can be installed into the mounting base 51 through the rear opening of the mounting base 51. In addition, the structure of the mounting base 51 can be further simplified, reducing production costs.

[0123] For example, see Figure 7 and Figure 8 One of the mounting base 51 and the base 542 is provided with a guide rail 542b extending in the direction of movement of the lever assembly 54, while the other is provided with a guide groove 51c extending in the direction of movement of the lever assembly 54. The guide rail 542b and the guide groove 51c are slidably engaged with each other. This effectively guides the linear reciprocating motion of the lever assembly 54 and reduces the risk of the lever assembly 54 getting stuck.

[0124] For example, see Figure 5 、 Figure 7 and Figure 8 The drainage drive device 50 includes a sealing ring 55. The sealing ring 55 surrounds the mounting hole 22a, and the lever 541 passes through the sealing ring 55 in a sealing manner. The sealing ring 55 is in sealing contact with the mounting hole 22a of the rear end cover 22, thereby preventing water in the outer tub from splashing out of the outer tub 20 through the mounting hole 22a.

[0125] The clothes processing device of the embodiment of the present application includes a control device and a driving motor.

[0126] The driving motor is used to drive the inner drum 10 to selectively rotate forward or reverse. It is understandable that the driving motor can directly drive the inner drum 10 to rotate, or can indirectly drive the inner drum 10 to rotate through a transmission member such as a belt.

[0127] The control device communicates with the drive motor and the motor assembly 52 to control the rotation sequence and rotation direction of the motor assembly 52 and the drive motor. In this way, the drainage control of the inner drum 10 is achieved through the rotation direction of the inner drum 10 and the extension and contraction of the lever assembly 54.
