[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] Currently, most washing machines are of an inner-outer-drum structure, with a closed space between the inner and outer drums. The washing water circulates back and forth between the inner and outer drums, and a large amount of dirt will accumulate on the drum wall over time.

[0044] In order to remove dirt on the barrel wall, existing washing machines generally have a cleaning brush between the inner and outer barrels. When the washing machine is running, the inner and outer barrels rotate relative to each other, so that the cleaning brush rubs against the inner wall of the outer barrel to clean the dirt. However, due to the structure of the inner and outer barrels, it is difficult to disassemble the cleaning brush, so it is difficult to remove the cleaning brush from between the inner and outer barrels. When the washing machine is running, the cleaning brush will continue to rub against the barrel wall and interfere with the rotation of the inner barrel, and the durability of the cleaning brush is relatively fast.

[0045] Therefore, the embodiment of the present application provides a drum assembly and a washing machine to solve the problem that the cleaning brush continuously interferes with the rotation of the inner drum and the cleaning brush wears out quickly during the operation of the washing machine.

[0046] See also Figures 1 to 4 , Figure 1 A schematic diagram of the first structure of the drum assembly provided in an embodiment of the present application; Figure 2 A second structural schematic diagram of a drum assembly provided in an embodiment of the present application; Figure 3 A third structural schematic diagram of the drum assembly provided in an embodiment of the present application; Figure 4 The fourth structural schematic diagram of the drum assembly provided in the embodiment of the present application. The drum assembly of the embodiment of the present application is suitable for a washing machine, wherein the drum assembly includes an inner barrel 11, an outer barrel 12 and a cleaning device 20, the inner barrel 11 is provided with a through hole 111, the outer barrel 12 is sleeved on the outer side of the inner barrel 11 and is spaced from the inner barrel 11, and there is a gap between the inner barrel 11 and the outer barrel 12 so that the inner barrel 11 and the outer barrel 12 can rotate relative to avoid interference; the cleaning device 20 is fixedly installed on the inner wall of the inner barrel 11, and the cleaning device 20 includes a cleaning component 23, and the cleaning component 23 can extend along the through hole 111 so that the cleaning component 23 abuts against the inner wall of the outer barrel 12, and when the inner barrel 11 and the outer barrel 12 rotate relative to each other, the cleaning brush 232 rubs against the outer barrel 12 and cleans the inner wall of the outer barrel 12.

[0047] The embodiment of the present application can control the cleaning component 23 to extend or retract along the through hole 111. When it is necessary to clean the inner wall of the outer barrel 12, the cleaning component 23 is extended from the through hole 111 and contacts the inner wall of the outer barrel 12, and the inner wall of the outer barrel 12 is cleaned by relative rotation of the inner and outer barrels 12. When it is not necessary to clean the inner wall of the outer barrel 12, the cleaning component 23 can be moved along the through hole 111 toward the side away from the outer barrel 12 to retract the cleaning component 23, so that it does not contact the inner wall of the outer barrel 12, thereby not interfering with the rotation of the inner barrel 11, reducing the rotational resistance between the inner barrel 11 and the outer barrel 12, and reducing the durable wear of the cleaning component 23.

[0048] For example, see Figures 5 to 12 , Figure 5 A schematic diagram of the first structure of the cleaning device provided in the embodiment of the present application; Figure 6 for Figure 5 A schematic cross-sectional view of the cleaning device shown along the AA direction;

[0049] Figure 7 for Figure 5 A schematic cross-sectional view of the cleaning device shown along the BB direction; Figure 8 for Figure 5 Another structural schematic diagram of the cleaning device shown; Fig. 9 A second structural schematic diagram of the cleaning device provided in an embodiment of the present application; Fig.10 for Fig. 9 A schematic cross-sectional view of the cleaning device along the CC direction shown; Fig.11 for Fig. 9 A schematic cross-sectional view of the cleaning device shown along the DD direction; Fig.12 for Fig. 9 Another structural schematic diagram of the cleaning device shown. The cleaning device 20 also includes a housing 21 and an adjusting device 25. The housing 21 has a receiving space 213. An opening 215 communicating with the receiving space 213 is provided on one side of the housing 21 close to the inner barrel 11. The cleaning component 23 is received in the receiving space 213, and at least a portion of the cleaning component 23 can extend out of the housing 21 along the opening 215. The adjusting device 25 is mounted on the housing 21 and connected to the cleaning component 23. The adjusting device 25 can control the cleaning component 23 to move toward or away from the opening 215, so that the cleaning component 23 extends out of the housing 21 along the opening 215 or is retracted along the opening 215.

[0050] Furthermore, in this embodiment, the cleaning assembly 23 includes a fixed plate 231 and a fixed brush. The cleaning brush 232 is fixed to the side of the fixed plate 231 away from the adjusting device 25 and extends toward the side close to the opening 215. The cleaning brush 232 can extend along the opening 215 and contact the inner wall of the outer barrel 12 to clean the outer barrel 12.

[0051] A limiting sleeve 2131 is also provided in the accommodating space 213. The limiting sleeve 2131 is located on a side of the fixing plate 231 away from the opening 215, and the limiting sleeve 2131 is fixed on the shell 21; the adjusting device 25 includes a rotating shaft 251 and a limiting structure 253. One end of the rotating shaft 251 is connected to the fixing plate 231, and the limiting structure 253 is fixed on the rotating shaft 251. The rotating shaft 251 can be moved axially along the rotating shaft 251 to make the limiting structure 253 abut against different positions without the limiting sleeve 2131, so as to push the fixing plate 231 toward the direction close to the opening 215 through the rotating shaft 251, that is, the cleaning component 23 is driven to move axially along the rotating shaft 251 through the rotating shaft 251, and the limiting structure 253 cooperates with the limiting sleeve 2131 on the shell 21 to limit the cleaning component 23 at different positions.

[0052] Furthermore, in this embodiment, the cleaning device 20 further includes a spring 27, which is located in the accommodating space 213, and one end of the spring 27 is fixed to the housing 21, and the other end of the spring 27 abuts against a side of the fixing plate 231 close to the cleaning brush 232. Figures 5 to 8 As shown, when the cleaning assembly 23 extends out of the opening 215, the spring 27 is compressed and applies a force to the fixing plate 231 in a direction away from the opening 215, so that the fixing plate 231 is placed against the housing 21, so that the position of the cleaning assembly 23 is fixed and displacement is avoided. In addition, when the cleaning assembly 23 needs to be retracted, since the cleaning assembly 23 is not connected to the rotating shaft 251, the spring 27 can provide a force to the fixing plate 231 in a direction away from the opening 215, so that the cleaning assembly 23 can be retracted into the accommodating space 213.

[0053] Please combine Figures 5 to 12 , see Fig.13 and Fig.14 , Fig.13 A schematic diagram of the structure of the first part and the regulating device in the cleaning device provided in an embodiment of the present application; Fig.14 for Fig.13 The limiting sleeve 2131 is provided with a limiting groove 2132, and the spring 27 includes an initial state and a compressed state. Figures 5 to 8 As shown, when the limiting structure 253 is located in the limiting groove 2132, the spring 27 is in the initial state, and the cleaning component 23 is located in the accommodating space 213, that is, the cleaning component 23 does not contact the inner wall of the outer tub 12. At this time, when the washing machine is started, the cleaning component 23 does not contact the outer tub 12, and will not generate friction with the outer tub 12 or interfere with the rotation of the outer tub 12; Figures 9 to 12As shown, when the limiting structure 253 abuts against the side of the limiting sleeve 2131 close to the opening 215, that is, the limiting structure 253 is moved toward the side close to the opening 215, and at the same time, the cleaning component 23 is driven to extend out of the opening 215, at this time, the limiting structure 253 is located between the limiting sleeve 2131 and the fixing plate 231, so that the fixing plate 231 compresses the spring 27, so that the spring 27 is in a compressed state, and a force is applied to the fixing plate 231 in a direction away from the opening 215, so that the limiting structure 253 abuts against the side of the limiting sleeve 2131 close to the opening 215.

[0054] After long-term use, the cleaning component 23 will inevitably be worn out, and dirt is easily deposited in the shell 21. Therefore, in this embodiment, the shell 21 includes a first part 211 and a second part 212, and the first part 211 and the second part 212 are surrounded by a receiving space 213, and the first part 211 and the second part 212 are detachably connected.

[0055] Specifically, see Figure 5 and Fig. 9 The first part 211 and the second part 212 can be connected to each other through the connecting piece 2115, that is, the connecting piece 2115 passes through the first part 211 and is connected to the second part 212, or the connecting piece 2115 passes through the second part 212 and is connected to the first part 211, so that the first part 211 and the second part 212 are connected, and the first part 211 and the second part 212 can be separated by disassembling the connecting piece 2115.

[0056] Since the shell 21 is installed on the inner wall of the inner tub 11, rather than between the inner tub 11 and the outer tub 12, it is convenient to disassemble the shell 21. When it is necessary to replace the cleaning component 23 or clean the dirt inside the shell 21, it is only necessary to remove the connector 2115 to separate the first part 211 and the second part 212, so as to open the shell 21, replace the cleaning component 23 or clean the dirt inside the shell 21.

[0057] It can be understood that the first part 211 and the second part 212 can also be clamped to each other through the clamping part 227. For example, a protrusion is set on the first part 211, and a corresponding clamping groove is set on the second part 212, so that the protrusion is clamped in the clamping groove to clamp the first part 211 and the second part 212. A limiting component can be added to the protrusion or the clamping groove to increase the connection stability of the first part 211 and the second part 212.

[0058] For further information, see Figures 5 to 12In this embodiment, the first part 211 is provided with a groove 2111, and the rotating shaft 251 is inserted into the shell 21 along the groove 2111. An adjusting disk 257 is provided at the end of the rotating shaft 251 away from the fixing plate 231. The adjusting disk 257 is located in the groove 2111. The adjusting disk 257 can rotate along the axis of the rotating shaft 251 and can move along the axial direction of the rotating shaft 251 to drive the rotating shaft 251 to rotate or move along the axis, thereby driving the limiting structure 253 to move, so that the limiting structure 253 can abut against different positions of the limiting sleeve 2131.

[0059] Specifically, in order to distinguish the rotation angle of the adjustment disk 257, the adjustment disk 257 is diamond-shaped, and the user can determine the position of the cleaning component 23 according to the direction of the corner after the adjustment disk 257 is rotated. It is understandable that the adjustment disk 257 can also be other shapes, so that the user can easily distinguish the rotation angle of the adjustment disk 257.

[0060] When the outer barrel 12 needs to be cleaned, the user can press the adjusting plate 257 to push the rotating shaft 251 to move toward the side close to the opening 215, so that the limiting structure 253 on the rotating shaft 251 is away from the limiting groove 2132 on the limiting sleeve 2131. At the same time, the rotating shaft 251 pushes the fixing plate 231 to move toward the side close to the opening 215, and the cleaning brush 232 extends out of the opening 215 and the spring 27 is compressed; after the limiting structure 253 is separated from the limiting groove 2132, the adjusting plate 257 is rotated to drive the limiting structure on the rotating shaft 251 to move toward the side close to the opening 215. 253 rotates. When the limiting structure 253 rotates to a certain distance from the limiting groove 2132, the adjusting disk 257 is loosened, and the spring 27 pushes the fixing plate 231 toward the side away from the opening 215, so that the fixing plate 231 and the rotating shaft 251 are moved toward the side away from the opening 215 by the elastic force generated by the compression of the spring 27, and the limiting structure 253 on the rotating shaft 251 is pressed against the end of the limiting sleeve 2131 away from the first part 211 by the elastic force provided by the spring 27, so that the cleaning component 23 is fixed in the extended position.

[0061] It can be understood that a groove 2111 is provided on the first portion 211, and the adjusting disk 257 is located in the groove 2111 regardless of whether the cleaning assembly 23 extends out of the opening 215, so as to avoid the adjusting disk 257 interfering with the clothes or the clothes being entangled on the adjusting disk 257 when washing clothes.

[0062] For example, see Figure 6 and Fig.10In this embodiment, a limiting portion 2123 is provided in the accommodating space 213. The limiting portion 2123 is provided on the side of the second portion 212 of the housing 21 facing the first portion 211. The limiting portion 2123 can limit the moving position of the fixing plate 231, that is, the length of the entire cleaning assembly 23 extending out of the opening 215. When the cleaning assembly 23 moves toward the side close to the outer barrel 12 and contacts the inner wall of the outer barrel 12, the fixing plate 231 abuts against the limiting portion 2123 to prevent the cleaning assembly 23 from extending out of the opening 215 too long. It can be understood that if the limiting portion 2123 is not provided, since the user cannot see between the inner barrel 11 and the outer barrel 12, when the cleaning brush 232 extends out of the opening 215, the cleaning assembly 23 may extend too long, and the cleaning brush 232 may excessively contact the inner wall of the outer barrel 12, causing the cleaning brush 232 to be forked or bent, which is not conducive to cleaning.

[0063] See also Figures 5 to 9 When the cleaning assembly 23 is retracted inside the housing 21, the limiting structure 253 is located in the limiting groove 2132, and the fixing plate 231 can abut against the side of the limiting sleeve 2131 close to the second portion 212 to limit the movement of the fixing plate 231. Figure 6 and Fig.10 A limiting block 2113 is also provided on the side of the first part 211 facing the second part 212. The limiting block 2113 can be of any shape. When the fixing plate 231 abuts against the limiting sleeve 2131, the limiting block 2113 also abuts against the side of the fixing plate 231 close to the first part 211. The spring 27 applies a force to the fixing plate 231 away from the side of the opening 215. The limiting block 2113 can provide support for the fixing plate 231, which can prevent the spring 27 from bending the fixing plate 231 and causing the fixing plate 231 to deform, making it difficult for the cleaning brush 232 to contact the outer barrel 12.

[0064] For example, see Figure 2 , Figure 3 , Figure 6 and Figure 7 In this embodiment, the inner barrel 11 is provided with a clamping hole 113, and the shell 21 is provided with a clamping portion 227. The clamping portion 227 is located on the side of the second portion 212 away from the first portion 211. The clamping portion 227 can be clamped with the clamping hole 113 to fix the cleaning device 20 with the inner barrel 11. The clamping of the shell 21 and the inner barrel 11 can facilitate the user's disassembly. The user can remove the cleaning device 20 from the inner barrel 11, and then separate the first portion 211 and the second portion 212 of the shell 21 to replace the cleaning component 23 or clean the dirt inside the shell 21.

[0065] It can be understood that the clamping portion 227 can be a hook structure, which can extend along the clamping hole 113 and abut against the outer wall of the inner barrel 11 through the hook to limit the movement of the cleaning device 20. The clamping portion 227 can also be fixedly connected to the inner barrel 11 by screws, which has good connection stability. The clamping portion 227 can also be other structures, and it only needs to fix the shell 21 and the inner barrel 11.

[0066] Since the shell 21 is arranged on the inner wall of the inner barrel 11, when washing clothes, the inner barrel 11 rotates. On the one hand, the part of the clothes close to the shell 21 and the relatively moving part rub against each other to produce a kneading effect; on the other hand, the shell 21 can drive the clothes to rotate together, and the clothes are lifted out of the liquid surface and sent to a certain height. Due to the effect of gravity, they fall back into the laundry liquid and collide with the laundry liquid to produce a beating and falling effect, thereby improving the washing effect. In this embodiment, the shell 21 of the cleaning device 20 can rub against the clothes and drive the clothes to move to improve the washing effect, without the need to separately set up lifting ribs and other structures to achieve this effect.

[0067] It can be understood that a plurality of cleaning devices 20 can be arranged along the inner wall of the inner tub 11 to enhance the washing effect.

[0068] This embodiment also provides a washing machine, which includes the drum assembly 100 in any of the above embodiments. It can be understood that the drum assembly 100 can be applicable to a drum washing machine or a pulsator washing machine.

[0069] The drum assembly and washing machine provided in the embodiment of the present application include an inner barrel, an outer barrel and a cleaning device, wherein a through hole is provided on the inner barrel, the outer barrel is sleeved on the outer side of the inner barrel and is spaced from the inner barrel, and there is a gap between the inner barrel and the outer barrel so that the inner barrel and the outer barrel can rotate relative to each other to avoid interference; the cleaning device is fixedly installed on the inner wall of the inner barrel, and the cleaning device includes a cleaning component, which can be extended along the through hole so that the cleaning component abuts against the inner wall of the outer barrel, and when the inner barrel and the outer barrel rotate relative to each other, the cleaning brush rubs against the outer barrel and cleans the inner wall of the outer barrel. The cleaning component can be extended or retracted along the through hole, and when it is necessary to clean the inner wall of the outer barrel, the cleaning component is extended from the through hole and contacts the inner wall of the outer barrel, and the inner wall of the outer barrel is cleaned by the relative rotation of the inner and outer barrels; when it is not necessary to clean the inner wall of the outer barrel, the cleaning component can be moved along the through hole toward the side away from the outer barrel to retract the cleaning component, so that it does not contact the inner wall of the outer barrel, thereby not interfering with the rotation of the inner barrel, reducing the rotation resistance between the inner barrel and the outer barrel, and reducing the durable loss of the cleaning component. The cleaning device also includes a shell and an adjusting device. The shell has a accommodating space. An opening connected to the accommodating space is provided on a side of the shell close to the inner barrel, and the cleaning component is accommodated in the accommodating space. At least part of the cleaning component can extend out of the shell along the opening. The adjusting device is installed on the shell and connected to the cleaning component. The adjusting device can move the cleaning component in a direction close to or away from the opening so that the cleaning component can be extended or retracted along the opening.
