[0034] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0035] In the embodiment of the present application, the orientation or position relationship of "upper", "lower", "top" and "bottom" is based on the attached Figure 1 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0036] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6 As shown, an embodiment of the present application provides a clothes processing device on one hand. The clothes processing device includes a box (not shown), a driving member (not shown) and a drum assembly 10 provided in any embodiment of the present application.

[0038] The type of the clothes processing device is not limited. For example, it can be a washing machine or a washer-dryer. Exemplarily, the clothes processing device is a drum washing machine.

[0039] The clothes treating device can perform at least one of the functions of washing and dehydrating clothes.

[0040] The box body can be understood as the appearance frame part of the clothes processing device, and at least part of the barrel assembly 10 is arranged in the box body. In other words, the box body can provide an installation base for the barrel assembly 10.

[0041] The type of the driving member is not limited. For example, it can be various types of motors. The driving member provides a driving force, thereby being able to drive the cylinder 12 to rotate around its axis.

[0042] like Figures 1 to 6 As shown, another aspect of the present application embodiment provides a cylinder assembly. The cylinder assembly 10 includes a cylinder 12 and a drainage member 13 .

[0043] The drum 12 has a laundry processing chamber 12a in which laundry can be placed and washed or dehydrated.

[0044] The specific structure of the drum body 12 is not limited. Exemplarily, the drum body 12 includes a drum body and a rear cover, and the rear cover is arranged at one end of the drum body, and the two define a clothes processing chamber 12a. It can be understood that in this embodiment, one side of the clothes processing chamber 12a is open.

[0045] Furthermore, in this embodiment, the drum 12 may also include a front cover, which is formed with a clothing loading port, and the front cover is arranged on the open side of the clothing processing chamber 12a. The user can put clothing into the clothing processing chamber 12a or take clothing out of the clothing processing chamber 12a through the clothing loading port.

[0046] Specifically, the driving member of the clothes processing device is drivingly connected to the drum 12 to drive the drum 12 to rotate. The driving member can provide driving force to the drum 12, and the drum 12 can rotate around its axis under the action of the driving force, thereby driving the clothes in the clothes processing chamber 12a to rotate accordingly, so that the effects of the washing and dehydration functions of the clothes processing device can be improved.

[0047] The drainage member 13 is used to drain the washing liquid in the laundry processing chamber 12a. That is, the drum assembly 10 of the embodiment of the present application is drained through the drainage member 13, that is, the drum 12 can hold water. When the laundry processing device is in the process of washing clothes, the washing liquid is contained in the drum 12, and the drum 12 can also be called a non-porous drum, which can avoid the problem of easy dirt and grime accumulation caused by holding water in an outer barrel in the prior art.

[0048] like Figure 1 and Figure 6 As shown, the drainage member 13 is provided with a water inlet 13a, a flow channel 13b and a water outlet 13c. The flow channel 13b extends radially along the cylinder 12. The cylinder 12 and the drainage member 13 rotate relative to each other so that the liquid in the clothing processing chamber 12a flows into the flow channel 13b through the water inlet 13a and is discharged from the cylinder 12 through the water outlet 13c.

[0049] During the drainage process, the drum 12 and the drainage member 13 rotate relative to each other. Specifically, the drum 12 rotates around its axis, the drainage member 13 is fixed, and the washing liquid in the laundry processing chamber 12a can flow into the flow channel 13b through the water inlet 13a. The washing liquid entering the flow channel 13b will naturally flow to the lower part of the flow channel 13b under the action of gravity, and will be discharged from the drum 12 through the water outlet 13c located at the lower part of the flow channel 13b.

[0050] The specific method of the washing liquid flowing into the flow channel 13b through the water inlet 13a is not limited. Figure 1 As shown, the water inlet 13a is located at the top of the clothing processing chamber 12a. During the washing process, the rotation speed of the drum 12 is relatively low, and most of the washing liquid is located at the bottom of the drum 12. Therefore, the washing liquid basically does not enter the flow channel 13b through the water inlet 13a. When the washing liquid needs to be discharged, the drum 12 can be rotated at a relatively high rotation speed so that the washing liquid is thrown to the top of the drum 12 under the action of centrifugal force, and then enters the flow channel 13b through the water inlet 13a. The washing liquid entering the flow channel 13b will naturally flow to the lower part of the flow channel 13b under the action of gravity, and be discharged from the drum 12 through the water outlet 13c located at the lower part of the flow channel 13b.

[0051] like Figure 1 and Figure 2 As shown, there is an installation gap 10a between the end of the drain member 13 away from the rotation axis of the cylinder 12 and the peripheral wall of the cylinder 12. In this way, the cylinder 12 will not interfere with the drain member 13 during the rotation process.

[0052] When the cylinder 12 and the drain member 13 rotate relative to each other, a part of the washing liquid will enter the installation gap 10a. The end surface of the drain member 13 away from the rotation axis of the cylinder 12 is provided with a water hole 13d, and the liquid in the installation gap 10a can flow into the flow channel 13b through the water hole 13d. In this way, the washing liquid in the installation gap 10a can enter the flow channel 13b through the water hole 13d, and be discharged from the cylinder 12 through the water outlet 13c located at the lower part of the flow channel 13b.

[0053] The number of water holes 13d is not limited, and can be one or more, for example.

[0054] It should be noted that, in the embodiments of the present application, a plurality refers to two or more.

[0055] When a plurality of water holes 13d are provided, the arrangement of the plurality of drainage holes on the end surface of the drainage member 13 at one end away from the rotation axis of the cylinder 12 is not limited.

[0056] For example, they may be distributed at intervals along the circumference of the cylinder 12 on the end surface of the drainage component 13 away from the rotation axis of the cylinder 12; they may also be distributed at intervals along the axial direction of the cylinder 12 on the end surface of the drainage component 13 away from the rotation axis of the cylinder 12; they may also be distributed in the form of an array on the end surface of the drainage component 13 away from the rotation axis of the cylinder 12; or they may be randomly distributed in an irregular form on the end surface of the drainage component 13 away from the rotation axis of the cylinder 12.

[0057] The drum assembly of the embodiment of the present application discharges the washing liquid in the laundry processing chamber 12a of the drum 12 through the drainage member 13, and there is no need to set a drainage hole on the drum 12, so the drum 12 can be designed without holes. An installation gap 10a is provided between the end of the drainage member 13 away from the rotation axis of the drum 12 and the peripheral wall of the drum 12, so that the drum 12 and the drainage member 13 can generate relative rotation. The drainage member 13 is provided with a water inlet 13a, a flow channel 13b and a water outlet 13c. The cylinder 12 and the drainage member 13 rotate relative to each other, so that most of the washing liquid in the clothing treatment chamber 12a can flow into the flow channel 13b through the water inlet 13a and be discharged from the cylinder 12 through the water outlet 13c. The end surface of the drainage member 13 away from the rotation axis of the cylinder 12 is provided with a water hole 13d, and a small part of the washing liquid entering the installation gap 10a can enter the flow channel 13b through the water hole 13d and be discharged from the cylinder 12 through the water outlet 13c. The water inlet 13a and the water hole 13d work together, so that the drainage performance of the drainage member 13 can be effectively improved, and the possibility of residual washing liquid in the clothing treatment chamber 12a is reduced, so that the cylinder 12 is convenient for the hole-free design.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, the water hole 13d faces the peripheral wall of the cylinder 12.

[0059] That is to say, the water hole 13d is generally extended from the installation gap 10a to the flow channel 13b. In this way, the washing liquid in the installation gap 10a encounters less resistance when flowing through the water port 13d to the flow channel 13b, which can improve the drainage efficiency of the water hole 13d.

[0060] like Figure 1 and Figure 2 As shown, in some embodiments, the size of the installation gap 10a is L1, and the range of L1 is 1 mm (millimeter) to 10 mm (millimeter).

[0061] For example, L1 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0062] By setting the range of L1 to 1mm~10mm, the size range of the installation gap 10a is between 1mm~10mm. In this way, relative rotation can be ensured between the cylinder 12 and the drainage component 13. At the same time, not too much washing liquid enters the installation gap 10a. More washing liquid still flows into the flow channel 13b through the water inlet 13a, thus ensuring the drainage efficiency of the drainage component 13.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the size of the installation gap 10a is L1, and the range of L1 is 2 mm (millimeter) to 3 mm (millimeter).

[0064] For example, L1 can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0065] By setting the range of L1 to 2mm to 3mm, the size range of the installation gap 10a is between 2mm and 3mm. The minimum size of the installation gap 10a is 2mm, that is, considering the processing tolerance that may occur in the cylinder 12 and the drainage member 13 during the processing, the size of the installation gap 10a is within this range, which can meet the processing technology requirements, thereby effectively reducing the problem of relative rotation between the cylinder 12 and the drainage member 13 after assembly due to the processing tolerance problem.

[0066] At the same time, the maximum size of the installation gap 10a is 3 mm. In this way, on the basis of meeting the process requirements, the size of the installation gap 10a is compressed as much as possible, so that the washing liquid can flow into the flow channel 13b through the water inlet 13a as much as possible, further improving the drainage efficiency of the drainage component 13.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the water hole 13d is D1, and the range of D1 is 2 mm (millimeter) to 8 mm (millimeter).

[0068] For example, D1 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc.

[0069] By setting the range of D1 to 2 mm to 8 mm, that is, the aperture of the water hole 13d is 2 mm to 8 mm, the washing liquid can enter the flow channel 13b through the water hole 13d, and at the same time, when the cylinder 12 and the drainage member 13 rotate relative to each other, a certain pressure difference can be generated between the installation gap 10a and the flow channel 13b, thereby forcing the washing liquid in the installation gap 10a to enter the flow channel 13b through the water hole 13d.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the water hole 13d is D1, and the range of D1 is 3 mm (millimeter) to 5 mm (millimeter).

[0071] For example, D1 can be 3mm, 3.2mm, 3.4mm, 3.6mm, 3.8mm, 4.0mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, etc.

[0072] By setting the range of D1 to 3 mm to 5 mm, that is, the aperture of the water hole 13d is 3 mm to 5 mm. The minimum aperture of the water hole 13d is 3 mm, that is, the tension of the washing liquid is taken into consideration, and the blocking effect of the water film formed by the washing liquid under the action of tension on the water hole 13d is reduced, that is, the permeability of the water hole 13d is guaranteed.

[0073] At the same time, the maximum aperture of the water hole 13d is 5 mm, so that the pressure difference effect formed between the installation gap 10a and the flow channel 13b is relatively good, so that the washing liquid in the installation gap 10a can better enter the flow channel 13b through the water hole 13d and be discharged through the water outlet 13c.

[0074] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, on a cross section parallel to the radial direction of the cylinder 12 , the cross section of one end of the drainage member 13 away from the rotation axis of the cylinder 12 is an arcuate surface 13e, and the arcuate surface 13e is adapted to the circumferential side wall of the cylinder 12.

[0075] Specifically, the center of the circle corresponding to the arc surface 13e falls on the rotation axis of the cylinder 12. That is, the end of the drainage member 13 away from the rotation axis of the cylinder 12 is the arc surface 13e, and the arc surface 13e is concentric with the inner wall of the cylinder 12.

[0076] It can be understood that, in this embodiment, the installation gap 10a is defined by the arc surface 13e and the peripheral wall of the cylinder 12, and the water hole 13d is set on the arc surface 13e. During the rotation of the cylinder 12, the size of the installation gap 10a remains consistent. In this way, during the rotation of the cylinder 12, the amount of washing liquid entering the installation gap 10a will not change substantially, and thus, the water hole 13d can more evenly guide the washing liquid into the flow channel 13b.

[0077] Of course, in other embodiments, the end of the drainage member 13 away from the rotation axis of the cylinder 12 may also be of other shapes. It is only necessary to maintain an installation gap 10a between the inner wall of the cylinder 12 and the drainage member 13 during the rotation of the cylinder 12, so that relative rotation can be generated between the cylinder 12 and the drainage member 13.

[0078] like Figure 1 and Figure 2 As shown, in some embodiments, the extension length of the end surface of the drainage member 13 away from the rotation axis of the cylinder 12 along the circumferential direction of the cylinder 12 is L2, and the range of L2 is 20 mm (millimeter) to 100 mm (millimeter).

[0079] For example, L2 can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, etc.

[0080] By setting the range of L2 to 20 mm to 100 mm, that is, the extension length of the end surface of the drain member 13 away from the rotation axis of the drum 12 along the circumference of the drum 12 is 20 mm to 100 mm, that is, the circumference of the arc surface 13e is 20 mm to 100 mm. In this way, the drain member 13 has a certain size in the circumference of the drum 12, which can ensure the drainage efficiency of the drain member 13. At the same time, the size of the drain member 13 will not be too large, thereby occupying too much volume in the laundry processing chamber 12a.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments, the extension length of the end surface of the drainage member 13 away from the rotation axis of the cylinder 12 along the circumferential direction of the cylinder 12 is L2, and the range of L2 is 40 mm (millimeter) to 60 mm (millimeter).

[0082] For example, L2 can be 40mm, 42mm, 44mm, 46mm, 48mm, 50mm, 52mm, 54mm, 56mm, 58mm, 60mm, etc.

[0083] By setting the range of L2 to 40 mm to 60 mm, that is, the extension length of the end surface of the drain member 13 away from the rotation axis of the cylinder 12 along the circumference of the cylinder 12 is 40 mm to 60 mm, that is, the circumference of the arc surface 13e is 40 mm to 60 mm. The minimum circumference of the arc surface 13e is 40 mm, which can ensure that the drain member 13 has a certain drainage efficiency. A sufficient number of water holes 13d can also be set on the arc surface 13e of 40 mm size, thereby meeting the discharge demand of the washing liquid in the installation gap 10a.

[0084] The maximum circumference of the arc surface 13e is 60 mm, that is, the size of the washing liquid in the flow channel 13b in the flow cross section will not be too large, and the length of the installation gap 10a in the circumferential direction of the cylinder 12 will not be too long. In this way, the amount of washing liquid entering the installation gap 10a is relatively small. At the same time, the flow rate of the washing liquid in the flow channel 13b can be increased while maintaining the same flow rate, thereby accelerating the discharge of the washing liquid from the water outlet 13c, and the drainage efficiency of the drainage component 13 can be improved.

[0085] like Figure 3 and Figure 4 As shown, in some embodiments, the laundry processing chamber 12 a includes a washing area 12 b and a drainage area 12 c arranged along the axial direction of the drum 12 .

[0086] For example, in some embodiments, the washing area 12b and the drainage area 12c are an integrated structure. Of course, in other embodiments, the washing area 12b and the drainage area 12c may also be a split structure.

[0087] For example, Figure 3 and Figure 4 As shown, in some embodiments, a partition 121 is disposed inside the drum 12 . The washing area 12 b and the drainage area 12 c are located on opposite sides of the partition 121 .

[0088] By arranging a partition 121 inside the drum 12, that is, the washing area 12b and the drainage area 12c are respectively located on the opposite sides of the partition 121, that is, the partition 121 can be used to separate the clothes and the drainage component 13 in the drainage area 12c, which can prevent the drainage component 13 arranged in the drainage area 12c from wearing the clothes or preventing the clothes from damaging the drainage component 13.

[0089] At least part of the drainage member 13 is disposed in the drainage area 12c. The drainage member 13 may be entirely disposed in the drainage area 12c, or part of the drainage member 13 may be disposed in the drainage area 12c.

[0090] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, the cylinder 12 has a drainage rotation direction, the water inlet 13 a is arranged opposite to the drainage rotation direction, and the water inlet 13 a is arranged at the upper part of the drainage member 13 .

[0091] The upper portion of the drainage member 13 is the portion of the drainage member 13 close to the peripheral wall of the cylinder 12 .

[0092] Under the action of external force, the cylinder 12 can rotate around its central axis. Figure 1As shown, the drainage rotation direction can be counterclockwise. Of course, the drainage rotation direction can also be clockwise.

[0093] During the drainage process, the washing liquid is located on the side close to the peripheral wall of the cylinder 12 under the action of centrifugal force, and rotates with the cylinder 12. The water inlet 13a is arranged opposite to the drainage rotation direction. In this way, during the drainage process of the cylinder 12, the washing liquid rotates with the cylinder 12 and rotates to the water inlet 13a. Then, the washing liquid can enter the flow channel 13b from the water inlet 13a and be discharged from the cylinder 12 through the water outlet 13c below the flow channel 13b.

[0094] like Figure 1 As shown, in some embodiments, the drainage member 13 is disposed on the upper portion of the cylinder 12 .

[0095] It should be noted that the upper portion of the cylinder 12 refers to a portion exceeding half of the height of the cylinder 12 .

[0096] By arranging the drainage member 13 at the upper part of the cylinder 12, the washing liquid flowing into the flow channel 13b can flow to the water outlet 13c under the action of gravity, and the collected water flow will not overflow, thereby improving the drainage efficiency.

[0097] like Figure 1 and Figure 2 As shown, in some embodiments, a plane perpendicular to the axis of the cylinder 12 is defined as a first plane, and on a cross section parallel to the first plane, a line connecting the midpoint of one end of the drainage member 13 away from the rotation center of the cylinder 12 and the rotation center of the cylinder 12 is Z1, wherein an angle between Z1 and the perpendicular bisector of the cylinder 12 is less than or equal to 60°.

[0098] It should be noted that the rotation center is the rotation point of the drainage member 13 around the rotation axis.

[0099] Exemplarily, one end of the drain member 13 is connected to the rotation center of the cylinder 12, and the other end extends radially outward. The line between the midpoint of the end of the drain member 13 away from the rotation center of the cylinder 12 and the rotation center of the cylinder 12 is Z1, that is, Z1 is equivalent to the central axis of the drain member 13 in the radial direction.

[0100] The center of the water outlet 13 c of the drainage member 13 is substantially coincident with or completely coincident with the rotation center of the cylinder 12 .

[0101] The perpendicular midline of the cylinder 12 refers to a vertical line passing through the central axis of the cylinder 12 , and the vertical line is perpendicular to both the horizontal plane and the central axis.

[0102] The included angle between Z1 and the perpendicular midline of the cylinder 12 is less than or equal to 60°, for example, 0°, 10°, 20°, 30°, 40°, 50° or 60°, etc.

[0103] By setting the included angle between Z1 and the perpendicular midline of the cylinder 12 to be less than or equal to 60°, it is more conducive to allowing the liquid flowing into the flow channel 13b to flow to the water outlet 13c under the action of gravity, and the collected water flow will not overflow, further improving the drainage efficiency.

[0104] For ease of understanding, Figure 1 As shown, from the perspective of the axial direction of the cylinder 12, the rotation direction of the cylinder 12 is counterclockwise for example. In this perspective, a coordinate system is established with the rotation center of the cylinder 12 as the center of the circle, the horizontal right direction as the X axis, and the vertical upward direction as the Y axis. The drain member 13 is located in the second quadrant, and one end of the drain member 13 is connected to the rotation center, and the angle between the line between the center of the other end and the rotation center and the Y axis is less than or equal to 60°.

[0105] like Figures 3 to 5 As shown, in some embodiments, the barrel assembly 10 includes a support unit 11 , a transmission member 15 and a flow guide member 14 , and the barrel 12 is rotatably supported on the support unit 11 through the transmission member 15 .

[0106] The barrel 12 is rotatably supported on the support unit 11. That is, the barrel 12 can rotate relative to the support unit 11.

[0107] The specific manner in which the cylinder 12 is rotatably supported on the support unit 11 by the transmission member 15 is not limited. Figures 3 to 5 As shown, the cylinder assembly 10 includes a first bearing 16, the inner ring of the first bearing 16 is sleeved on the transmission member 15, the support unit 11 has a connecting through hole 11a, the outer ring of the first bearing 16 is supported on the hole wall of the connecting through hole 11a, and the cylinder 12 is sleeved on one end of the transmission member 15. The transmission member 15 can rotate relative to the support unit 11 under the action of external force, and drive the cylinder 12 to rotate. At the same time, the support unit 11 can also support the cylinder 12 through the transmission member 15.

[0108] The transmission member 15 is provided with a first installation channel 15a along the axial direction, one end of the guide member 14 is connected to the drainage member 13, and the other end passes through the first installation channel 15a and is fixedly connected to the support unit 11, and the guide member 14 is provided with a guide channel 141a along its axial direction, and the two ends of the guide channel 141a are respectively connected to the water outlet 13c and the outside.

[0109] The flow guide member 14 can facilitate the arrangement of the drainage member 13 in the laundry processing chamber 12a on the one hand, and can discharge the washing liquid reaching the water outlet 13c to the outside on the other hand.

[0110] By setting the first installation channel 15a penetrating along the axial direction of the transmission member 15, the guide channel 141a can be arranged along the first installation channel 15a, and the guide member 14 does not need to bypass the outer peripheral wall of the cylinder 12 and the support unit 11 to achieve fixed connection with the support unit 11. In this way, the arrangement distance of the guide channel 141a can be shortened as much as possible, reducing the complexity of the guide channel 141a, making the structure of the cylinder assembly 10 simpler. At the same time, the first installation channel 15a provides a layout space for the guide member 14, which facilitates the layout of the guide member 14 and makes the structure of the cylinder assembly 10 more compact.

[0111] In addition, the guide channel 141a is arranged along the axial direction of the transmission member 15, so the guide channel 141a can be designed to be straighter, which can reduce the drainage resistance and shorten the drainage distance to a certain extent, and improve the drainage effect of the guide channel 141a.

[0112] The specific structure of the flow guide 14 is not limited. Figures 3 to 6 As shown, in some embodiments, the guide member 14 includes a water pipe 141 having a guide channel 141a and a hollow shaft 142 having a second installation channel 142a. The hollow shaft 142 is inserted into the first installation channel 15a and one end is connected to the drainage member 13, and the other end is fixedly engaged with the support unit 11. The transmission member 15 is rotatably supported on the hollow shaft 142, and the water pipe 141 is arranged in the second installation channel 142a. The two ends of the water pipe 141 are respectively connected to the drainage member 13 and the support unit 11.

[0113] The specific manner in which the transmission member 15 is rotatably supported on the hollow shaft 142 is not limited. Figures 3 to 5 As shown, the cylinder assembly 10 also includes a second bearing 17, the inner ring of the second bearing 17 is sleeved on the hollow shaft 142, and the outer ring of the second bearing 17 is supported on the peripheral wall of the first mounting channel 15a of the transmission member 15, so that the transmission member 15 can rotate around its axial direction, and the hollow shaft 142 can maintain a relatively static state. At the same time, the hollow shaft 142 and the transmission member 15 can form mutual support.

[0114] The number of the second bearings 17 is not limited. Figure 5 As shown, there are two second bearings 17, one of which is arranged at one end close to the cylinder 12, and the other is arranged at one end away from the cylinder 12. By arranging the second bearings 17 at both ends of the hollow shaft 142, the supporting effect of the hollow shaft 142 is better.

[0115] There is a certain gap between the peripheral wall of the hollow shaft 142 and the peripheral wall of the first installation channel 15a. The outer ring of the second bearing 17 rotates with the transmission member 15, and the inner ring of the second bearing 17 does not rotate, thereby being able to support the hollow shaft 142. In this way, mutual support between the rotating transmission member 15 and the non-rotating hollow shaft 142 is achieved.

[0116] The hollow shaft 142 is relatively stationary, so that the water conduit 141 can be directly placed in the second installation channel 142a.

[0117] It is understandable that impurities such as lint may be generated during the washing process of clothes. During the drainage process, these impurities may enter the guide channel 141a and block the guide channel 141a. The water pipe 141 can be relatively easily pulled out from the second installation channel 142a, making it easier to repair and handle the guide channel 141a when it is blocked.

[0118] like Figures 3 to 5 As shown, in some embodiments, the hollow shaft 142 is anti-rotationally matched with the support unit 11. The other end of the hollow shaft 142 is connected to the drain member 13, so that the risk of the drain member 13 rotating inside the laundry processing chamber 12a can be reduced, and the anti-rotation cooperation and the fixed connection work in coordination, which can further improve the connection stability of the drain member 13.

[0119] The specific structure of the hollow shaft 142 and the support unit 11 is not limited. Figure 4 and Figure 5 As shown, in some embodiments, an external spline 142b is provided on the hollow shaft 142, the support unit 11 has a connecting through hole 11a, an internal spline 112b is provided on the inner wall of the connecting through hole 11a, at least a portion of the hollow shaft 142 is provided in the connecting through hole 11a, and the external spline 142b is engaged with the internal spline 112b to prevent rotation.

[0120] It can be understood that at least a portion of the transmission member 15 is also arranged in the connecting through hole 11a, and one end of the transmission member 15 will not completely exceed the connecting through hole 11a, that is, there is an idle space in the connecting through hole 11a, one end of the hollow shaft 142 passes through the first installation channel 15a and enters this idle space, the internal spline 112b of the connecting through hole 11a is arranged on the peripheral wall of this idle space, and the part of the hollow shaft 142 passing through the first installation channel 15a is provided with an external spline 142b, and the tooth portion of the external spline 142b and the tooth portion of the internal spline 112b are engaged with each other, thereby limiting the rotation between the two.

[0121] In some other embodiments, protrusions and grooves may be respectively provided on the outer peripheral wall of the hollow shaft 142 and the hole wall of the connecting through hole 11a, and the protrusions may be inserted into the grooves, thereby also achieving anti-rotation fit.

[0122] like Figures 4 to 6 As shown, in a specific embodiment, the support unit 11 includes a support member 111 and a fixing member 112, the fixing member 112 is provided with a mounting hole 112a, an internal spline 112b is provided on the hole wall of the mounting hole 112a, and the mounting hole 112a is a part of the connecting through hole 11a.

[0123] In this embodiment, the transmission member 15 is rotatably supported on the support member 111, the cylinder 12 and the fixing member 112 are respectively located on opposite sides of the support member 111, the hollow shaft 142 passes through the support member 111 and is anti-rotationally engaged with the fixing member 112, and the water pipe 141 is fixedly connected to the side of the fixing member 112 away from the support member 111.

[0124] like Figures 3 to 5 As shown, one end of the water conduit 141 away from the drainage member 13 protrudes along the radial direction of the water conduit 141 to form a connecting portion 141 b, and the connecting portion 141 b is fixedly connected to the supporting unit 11.

[0125] That is to say, the hollow shaft 142 plays the role of supporting the water pipe 141 in the first installation channel 15a. The water pipe 141 is fixedly connected to the support unit 11. When the water pipe 141 needs to be pulled out from the second installation channel 142a of the hollow shaft 142, the connection between the connecting part 141b and the support unit 11 can be released, so that the water pipe 141 can be pulled out along the axial direction of the second installation channel 142a.

[0126] Specifically, when the supporting unit 11 includes the supporting member 111 and the fixing member 112 , the connecting portion 141 b is fixedly connected to the fixing member 112 .

[0127] like Figure 5 As shown, a connecting groove 13n is provided on the drainage member 13, one end of the hollow shaft 142 close to the drainage member 13 is provided in the connecting groove 13n, and the water outlet 13c is opened on the groove wall of the connecting groove 13n.

[0128] That is to say, the drain member 13 is connected to the hollow shaft 142. Since the hardness of the hollow shaft 142 is better than that of the water pipe 141, the drain member 13 is connected to the hollow shaft 142 and supported by the hollow shaft 142, so that the load-bearing effect of the drain member 13 is better.

[0129] The connecting groove 13n can provide an installation space for the hollow shaft 142 , thereby facilitating the connection relationship between the drain member 13 and the hollow shaft 142 .

[0130] Since the water pipe 141 is arranged inside the hollow shaft 142, the water pipe 141 will be located in the connecting groove 13n after passing through the hollow shaft 142. By opening the water outlet 13c on the groove wall of the connecting groove 13n, the connection relationship between the water outlet 13c and the guide channel 141a can be easily achieved.
