The washing device 20 further comprises a casing 21 and an adjusting device 25, the casing 21 has an accommodating space 213, an opening 215 communicated with the accommodating space 213 is opened at one side of the casing 21 close to the inner barrel 11, the cleaning assembly 23 is accommodated in the accommodating space 213, and at least part of the cleaning assembly 23 can extend out of the casing 21 along the opening 215; an adjustment device 25 is mounted to the housing 21 and connected to the cleaning assembly 23, and the adjustment device 25 can control the cleaning assembly 23 to move toward or away from the opening 215 so as to extend the cleaning assembly 23 out of the housing 21 along the opening 215 or retract the cleaning assembly 23 along the opening 215.

Further, in the present embodiment, the cleaning assembly 23 includes a fixing plate 231 and a fixing brush, the cleaning brush 232 is fixed on a side of the fixing plate 231 away from the adjusting device 25 and extends toward a side close to the opening 215, and the cleaning brush 232 can extend along the opening 215 and contact an inner wall of the outer tub 12 to clean the outer tub 12.

A limiting sleeve 2131 is further arranged in the accommodating space 213, the limiting sleeve 2131 is positioned on one side of the fixing plate 231, which is far 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, the limiting structure 253 is fixed on the rotating shaft 251, the rotating shaft 251 can move along the axial direction of the rotating shaft 251 to abut the limiting structure 253 against different positions of the non-limiting sleeve 2131, so that the fixing plate 231 is pushed by the rotating shaft 251 to move towards the direction close to the opening 215, that is, the cleaning assembly 23 is driven by the rotating shaft 251 to move along the axial direction of the rotating shaft 251, and the limiting structure 253 is matched with the limiting sleeve 2131 on the housing 21 to limit the cleaning assembly 23 at different positions.

Further, in the embodiment, the cleaning device 20 further includes a spring 27, the spring 27 is located in the accommodating space 213, and one end of the spring 27 is fixed to the housing 21, and the other end abuts against one side of the fixing plate 231 close to the cleaning brush 232. As shown in fig. 5 to 8, 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 abutted against the housing 21, and the position of the cleaning assembly 23 is fixed and prevented from being displaced. 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.

Referring to fig. 13 and 14 in conjunction with fig. 5 to 12, fig. 13 is a schematic structural diagram of a first portion and an adjusting device in a cleaning device according to an embodiment of the present disclosure; fig. 14 is a schematic structural view of an adjusting device in the cleaning device shown in fig. 13. The limiting sleeve 2131 is provided with a limiting groove 2132, the spring 27 has an initial state and a compressed state, as shown in fig. 5 to 8, when the limiting structure 253 is located in the limiting groove 2132, the spring 27 is in the initial state, the cleaning assembly 23 is located in the accommodating space 213, i.e., the cleaning assembly 23 is not in contact with the inner wall of the outer tub 12, at this time, the washing machine is started, the cleaning assembly 23 is not in contact with the outer tub 12, and does not generate friction with the outer tub 12 or interfere the rotation of the outer tub 12; as shown in fig. 9 to 12, when the position-limiting structure 253 abuts against the side of the position-limiting sleeve 2131 close to the opening 215, that is, the position-limiting structure 253 moves towards the side close to the opening 215 and drives the cleaning assembly 23 to extend out of the opening 215, the position-limiting structure 253 is located between the position-limiting sleeve 2131 and the fixing plate 231, so that the fixing plate 231 compresses the spring 27, the spring 27 is in a compressed state, and a force in a direction away from the opening 215 is applied to the fixing plate 231, so that the position-limiting structure 253 abuts against the side of the position-limiting sleeve 2131 close to the opening 215.

Since the cleaning assembly 23 is still inevitably worn after long-term use and dirt is easily deposited in the housing 21, in the embodiment, the housing 21 includes the first portion 211 and the second portion 212, the first portion 211 and the second portion 212 are enclosed to form the accommodating space 213, and the first portion 211 and the second portion 212 are detachably connected.

Specifically, referring to fig. 5 and 9, the first portion 211 and the second portion 212 may be connected to each other by a connection member 2115, that is, the connection member 2115 penetrates the first portion 211 to connect with the second portion 212, or the connection member 2115 penetrates the second portion 212 to connect with the first portion 211, so that the first portion 211 and the second portion 212 are connected, and the first portion 211 and the second portion 212 may be separated by detaching the connection member 2115.

Since the case 21 is mounted to the inner wall of the inner tub 11, not between the inner tub 11 and the outer tub 12, the case 21 is easily disassembled. When it is desired to replace the cleaning assembly 23 or clean the interior of the housing 21, the connection 2115 is simply removed to separate the first portion 211 and the second portion 212 to open the housing 21 for replacing the cleaning assembly 23 or cleaning the interior of the housing 21.

It can be understood that the first portion 211 and the second portion 212 can also be clamped with each other by the clamping portion 227, for example, a protrusion is disposed on the first portion 211, a slot is correspondingly disposed on the second portion 212, so that the protrusion is clamped in the slot, so that the first portion 211 and the second portion 212 are clamped, and a limiting component can be added in the protrusion or the slot to increase the connection stability of the first portion 211 and the second portion 212.

Further, referring to fig. 5 to 12, in the present embodiment, the first portion 211 is provided with a groove 2111, the rotating shaft 251 is inserted into the housing 21 along the groove 2111, an adjusting disc 257 is disposed at an end of the rotating shaft 251 away from the fixing plate 231, the adjusting disc 257 is located in the groove 2111, the adjusting disc 257 can rotate along an axis of the rotating shaft 251 and can move along an axial direction of the rotating shaft 251 to drive the rotating shaft 251 to rotate or move along the axis, so as to drive the limiting structure 253 to move, so that the limiting structure 253 can abut against different positions of the limiting sleeve 2131.

Specifically, in order to distinguish the rotation angle of the adjustment dial 257, the adjustment dial 257 has a diamond shape, and the user can determine the position of the cleaning assembly 23 according to the angular orientation of the rotation rear edge of the adjustment dial 257. It is understood that the adjustment plate 257 may have other shapes, so that the user can easily recognize the rotation angle of the adjustment plate 257.

When it is required to wash the outer tub 12, the user may press the adjusting plate 257 to push the rotating shaft 251 to move toward a 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, and at the same time, the rotating shaft 251 pushes the fixing plate 231 to move toward a side close to the opening 215, the cleaning brush 232 protrudes 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 253 on the rotating shaft 251 to rotate, when the limiting structure 253 rotates to a certain distance away from the limiting groove 2132, the adjusting plate 257 is loosened, the spring 27 pushes the fixing plate 231 towards one side away from the opening 215, so that the fixing plate 231 and the rotating shaft 251 move towards one side away from the opening 215 through the elastic force generated by the compression of the spring 27, and the limiting structure 253 on the rotating shaft 251 abuts against one end of the limiting sleeve 2131 away from the first portion 211 through the elastic force provided by the spring 27, so that the cleaning assembly 23 is fixed at the extending position.

It will be appreciated that a notch 2111 is provided in the first portion 211, and the adjustment dial 257 is positioned within the notch 2111 regardless of whether the cleaning assembly 23 protrudes out of the opening 215, thereby preventing the adjustment dial 257 from interfering with the laundry or the laundry from being entangled around the adjustment dial 257 while the laundry is being washed.

Referring to fig. 6 and 10, in the present embodiment, a position-limiting portion 2123 is disposed in the accommodating space 213, the position-limiting portion 2123 is disposed on a side of the second portion 212 of the housing 21 facing the first portion 211, and the position-limiting portion 2123 can limit a moving position of the fixing plate 231, that is, a length of the whole cleaning assembly 23 extending out of the opening 215. When the cleaning assembly 23 moves toward a side close to the outer tub 12 and contacts the inner wall of the outer tub 12, the fixing plate 231 abuts against the stopper 2123 to prevent the cleaning assembly 23 from extending out of the opening 215 for 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 extending distance of the cleaning assembly 23 may be too long, the cleaning brush 232 excessively contacts the inner wall of the outer barrel 12, and the cleaning brush 232 is branched and bent, which is not beneficial to cleaning.

Referring to fig. 5 to 9, when the cleaning assembly 23 is retracted into the housing 21, the limiting structure 253 is located in the limiting groove 2132, and the fixing plate 231 can abut against a side of the limiting sleeve 2131 close to the second portion 212 to limit the movement of the fixing plate 231. Referring to fig. 6 and 10, a stopper 2113 is further disposed on a side of the first portion 211 facing the second portion 212, and the stopper 2113 may have any shape. When the fixing plate 231 abuts against the limiting sleeve 2131, the limiting block 2113 also abuts against one 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 opening 215, and the stopper 2113 can support the fixing plate 231, so as to prevent the fixing plate 231 from being deformed due to the fixing plate 231 being bent by the spring 27, and the cleaning brush 232 from being difficult to contact with the outer tub 12.

For example, referring to fig. 2, fig. 3, fig. 6 and fig. 7, in the present embodiment, the inner tub 11 is provided with a fastening hole 113, the shell 21 is provided with a fastening portion 227, the fastening portion 227 is located on a side of the second portion 212 far away from the first portion 211, and the fastening portion 227 can be fastened with the fastening hole 113, so that the cleaning device 20 is fixedly connected with the inner tub 11. The casing 21 is fastened to the inner tub 11 to be easily removed by a user, and the user may detach the washing device 20 from the inner tub 11, separate the first part 211 and the second part 212 of the casing 21, and replace the cleaning assembly 23 or wash dirt inside the casing 21.

It is understood that the fastening portion 227 can be a hook structure, and the hook structure can extend along the fastening hole 113 and abut against the outer wall of the inner barrel 11 through the hook structure to limit the movement of the cleaning device 20. The clamping part 227 can also be fixedly connected with the inner barrel 11 through screws, and has better connection stability. The engaging portion 227 may have other structures, and only the casing 21 and the inner tub 11 need to be fixedly connected.

Since the casing 21 is disposed on the inner wall of the inner tub 11, when washing the laundry, the inner tub 11 rotates, and on the one hand, a portion of the laundry close to the casing 21 rubs against a relatively moving portion to generate a rubbing action; on the other hand, the casing 21 can drive the clothes to rotate together, the clothes are lifted out of the liquid level and conveyed to a certain height, and fall into the laundry detergent again under the action of gravity, and impact with the laundry detergent to generate a bar beating and falling effect, so that the washing effect is improved. The embodiment can rub the casing 21 of the washing device 20 with the clothes to drive the clothes to move so as to improve the washing effect, and does not need to separately provide structures such as lifting ribs to realize the washing effect.

It can be understood that the washing device 20 may be provided in plurality along the inner wall of the inner tub 11 to enhance the washing effect.

The present embodiment also provides a washing machine including the drum assembly 100 of any one of the above embodiments. It is understood that the drum assembly 100 may be applied to a drum washing machine or a pulsator washing machine.
