DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0038] With the acceleration of modern life pace, laundry treatment devices have become indispensable equipment in both home and commercial environments. It not only greatly improves the efficiency of clothes cleaning, but also saves labor and time costs. The laundry treatment device includes a barrel assembly, and during long-term use, dirt and bacteria will inevitably accumulate on the barrel wall of the barrel assembly, which not only affects the cleaning effect, but also may pose a threat to the health of users. The traditional cleaning method usually requires disassembling the inner barrel, which not only takes time and effort, but also may cause damage to the equipment during disassembly and reinstallation.

[0039] Please refer to Figure 1 , the present embodiment provides a laundry treatment device 100, the laundry treatment device 100 includes a barrel assembly 10, a cover structure 20 and a cleaning piece 30, the barrel assembly 10 includes an outer barrel 11 and an inner barrel 12 rotatably arranged in the outer barrel 11, the inner barrel 12 is the part directly contacted by clothes, the inner barrel 12 has a clothes treatment cavity, responsible for containing clothes and water during the washing process, and the user puts the clothes to be treated into the clothes treatment cavity through the clothes feeding port, while the outer barrel 11 plays a role of protecting and supporting the inner barrel 12. Further, the outer barrel 11 and the inner barrel 12 define a gap cavity 10a, which can be understood that the gap cavity 10a is formed by the outer peripheral wall of the inner barrel 12 and the inner peripheral wall of the outer barrel 11.

[0040] As Figure 1 and Figure 2As shown, further, the gap cavity 10a is provided with an opening 10b on one side thereof, the opening 10b is located at the top end of the bucket assembly 10 when the bucket assembly 10 is axially along the up-down direction, the opening 10b is located at the front end of the bucket assembly 10 when the bucket assembly 10 is axially along the horizontal direction or the inclined direction at an acute angle with the horizontal direction, the cover structure 20 is annular, connected with the bucket assembly 10 and located at the opening 10b, and the cover structure 20 has a mounting area 20a, and the cleaning piece 30 includes a support structure 31 and a cleaning brush 32 connected to the support structure 31.

[0041] Specifically, the cleaning piece 30 has a dimension of the cleaning brush 32 in the first direction AA greater than a dimension in the second direction BB, and the first direction AA and the second direction BB are arranged at an angle, wherein the first direction AA can be one of the radial directions of the bucket assembly 10, i.e. the width direction of the cleaning piece 30 towards the center of the bucket assembly 10, and the second direction BB is substantially perpendicular to the radial direction, i.e. the thickness direction of the cleaning piece 30 towards the circumferential direction of the bucket assembly 10.

[0042] The cleaning piece 30 can rotate relative to the cover structure 20 to switch between the first position and the second position, so that the cleaning brush 32 is in clearance fit with the mounting area 20a in the first position. Understandably, in the first position, the cleaning piece 30 is easier to pass through the mounting area 20a, and the scratching between the cleaning brush 32 and the mounting area 20a is reduced, unnecessary wear of the cleaning brush 32 is reduced, and the service life of the cleaning brush 32 is improved. And in the first position, the cleaning brush 32 does not contact the cavity wall of the gap cavity 10a.

[0043] In the second position of the cleaning piece 30, at least part of the cleaning brush 32 contacts the cavity wall of the gap cavity 10a, which can be that all the free ends of the cleaning brush 32 abut on the cavity wall of the gap cavity 10a, or part of the free ends of the cleaning brush 32 abut on the cavity wall of the gap cavity 10a, which can effectively clean the cavity wall of the gap cavity 10a. Understandably, the more free ends of the cleaning brush 32 abut on the cavity wall of the gap cavity 10a, the better the cleaning effect is, and the support structure 31 is limited and fixed with the mounting area 20a to ensure that the cleaning piece 30 does not deviate from its position during cleaning, maintain the contact between the cleaning brush 32 and the cavity wall of the gap cavity 10a, and provide stable cleaning effect. And the larger dimension of the cleaning brush 32 in the first direction AA means that the cleaning brush 32 can better contact the cavity wall of the gap cavity 10a in the second position, ensuring that during the rotation of the bucket assembly 10, the cleaning dead angle of the cleaning brush 32 is reduced.

[0044] As Figure 2 and Figure 3As shown, in some embodiments, the support structure 31 comprises a brush rod 311 and a brush handle 312, the brush rod 311 is connected with the cleaning brush 32 at a part of the outer circumferential surface, the cleaning brush 32 is arranged to extend along the first direction AA, and the brush rod 311 can drive the cleaning brush 32 to rotate in the gap cavity 10a, and the brush handle 312 is connected with the brush rod 311, and the brush handle 312 is detachably connected with the mounting area 20a, that is, when the brush handle 312 is not limitedly matched with the mounting area 20a, the cleaning piece 30 can be adjusted to an angle at which the cleaning brush 32 has a better contact effect with the cavity wall of the gap cavity 10a, and after being adjusted to a suitable angle, the brush handle 312 is connected with the mounting area 20a so that the cleaning piece 30 can be kept at the better position, thereby avoiding incomplete cleaning caused by instability of the cleaning piece 30 during cleaning.

[0045] The connection mode of the brush handle 312 and the mounting area 20a includes at least one of clamping, insertion, screwing, bonding and magnetic attraction. Different connection modes provide multiple choices, and these connection modes are generally simple to operate, and users can easily connect and separate the brush handle 312 and the mounting area 20a, thereby improving the convenience of use. The application does not limit the connection mode of the brush handle 312 and the mounting area 20a.

[0046] As shown in Figure 4 and Figure 5 Specifically, the mounting area 20a comprises a limiting part 20a2, and the brush handle 312 is provided with a limiting matching part 3121, the limiting part 20a2 and the limiting matching part 3121 cooperate to limit the cleaning piece 30, the cooperation of the limiting part 20a2 and the limiting matching part 3121 can improve the accurate positioning of the cleaning piece 30 in the mounting area 20a, improve the cooperation precision between the cleaning brush 32 and the bucket assembly 10, and thereby enhance the stability of the cleaning piece 30 during cleaning.

[0047] Exemplarily, the limiting matching part 3121 is a limiting protrusion, and the limiting part 20a2 is a limiting hole, the limiting protrusion and the limiting hole are inserted, the design of the limiting protrusion and the limiting hole ensures the accurate alignment between the brush handle 312 and the mounting area 20a, the user only needs to insert the limiting protrusion into the limiting hole to complete the connection, the operation is simple, and there is no need for a complex alignment process, and after the limiting protrusion is inserted into the limiting hole, a stable connection is provided, and the relative movement between the brush handle 312 and the mounting area 20a caused by vibration during cleaning is reduced.

[0048] In one arrangement, the limiting holes are provided in plurality, and the plurality of limiting holes are divided into two groups, and each group of limiting holes can be two, three, etc. The two groups of limiting holes are respectively located on the two sides of the installation hole 20a1 along the radial direction of the inner barrel 12. Understandably, when the brush rod 311 is inserted into the installation hole 20a1, the limiting protrusion of the brush handle 312 is not aligned with the limiting hole at this time, that is, the limiting protrusion and the limiting hole have a foolproof effect, and the limiting protrusion abuts on the end face of the installation area 20a. Therefore, even if the user cannot see the abutting condition of the cleaning brush 32 in the gap cavity 10a, the position of the cleaning brush 32 can also be determined through the connection state of the brush handle 312. The user rotates the brush handle 312 to insert the limiting protrusion into the limiting hole. During this process, the cleaning brush 32 is synchronously abutted on the cavity wall of the gap cavity 10a, which ensures the synchronization of the cleaning action and the consistency of the cleaning effect.

[0049] Further, the installation area 20a further comprises an installation hole 20a1 which is spaced apart from the limiting portion 20a2, and the installation hole 20a1 is in communication with the gap cavity 10a, and the brush rod 311 can pass through the installation hole 20a1. Understandably, the brush rod 311 is located at the end of the brush rod 311, and the user can hold the brush handle 312 to pass the brush rod 311 into the installation hole 20a1, and the brush rod 311 is connected to the brush handle 312 and extends along the axial direction of the barrel assembly 10. The cleaning brush 32 does not need to fully cover the outer peripheral wall of the brush rod 311, for example, the cleaning brush 32 can cover the single-side outer peripheral wall of the brush rod 311 from top to bottom, which reduces the use of materials and reduces the manufacturing cost.

[0050] The installation hole 20a1 extends along the second direction BB, that is, along the circumferential direction of the end cover assembly, and is provided in an overall narrow and long manner. Since the installation hole 20a1 is provided in a narrow and long manner and extends along the circumferential direction of the end cover assembly, it can avoid opening a hole with a large radial size on the barrel cover 21, reduce the weakening of the radial strength of the end cover structure, and reduce the risk of cracking of the end cover structure. Specifically, the installation hole 20a1 can be a rectangular hole, and the long side of the rectangular hole is arranged at an angle with the radial direction of the barrel assembly 10.

[0051] As Figure 6 and Figure 7It is shown that the cleaning piece 30 has a first position and a second position, and the specific steps of the laundry treatment device 100 in the embodiment for cleaning the cavity wall of the gap cavity 10a using the cleaning piece 30 are as follows: the user inserts the cleaning brush 32 part of the cleaning piece 30 into the mounting hole 20a1, and during the insertion, the free end of the cleaning brush 32 is in the same direction as the extension direction of the mounting hole 20a1. Since the part of the cleaning piece 30 where the cleaning brush 32 is arranged is in clearance fit with the mounting hole 20a1, the brush rod 311 and the cleaning brush 32 easily and smoothly pass through the mounting hole 20a1. At this time, the cleaning brush 32 is not in contact with the cavity wall of the gap cavity 10a. After the insertion is completed, the user rotates the brush handle 312 or the brush rod 311 to drive the cleaning brush 32 to abut against the cavity wall of the gap cavity 10a. After reaching the abutting position, the brush handle 312 can be connected with the mounting area 20a to position the cleaning piece 30 at the position where the cleaning brush 32 is in contact with the cavity wall of the gap cavity 10a, i.e., the second position.

[0052] To reduce the possibility of scratching the hole wall when the cleaning brush 32 passes through the mounting hole 20a1, during the process of the cleaning brush 32 passing through the mounting hole 20a1, the free end of the cleaning brush 32 away from the brush rod 311 has a gap with the hole wall of the mounting hole 20a1. The existence of the gap reduces the contact between the cleaning brush 32 and the hole wall when the cleaning brush 32 passes through the mounting hole 20a1, reduces the friction between the cleaning brush 32 and the hole wall, and maintains the overall shape and cleaning effect of the cleaning brush 32.

[0053] In the first position, the cleaning piece 30 is not inserted into the mounting hole 20a1 in a state that the cleaning brush 32 directly abuts against the cavity wall of the gap cavity 10a after the insertion, but is abutted against the inner tub 12 by rotating in the gap cavity 10a. This reduces the contact and scratching between the cleaning brush 32 and the hole wall of the mounting hole 20a1, protects the integrity of the cleaning brush 32, and prolongs the service life.

[0054] In one arrangement, the extension direction of the free end of the cleaning brush 32 is substantially 90° to the radial direction of the tub assembly 10. Therefore, after the insertion is completed, the cleaning brush 32 can be rotated by 90° toward the cavity wall of the gap cavity 10a to make the cleaning brush 32 abut against the cavity wall of the gap cavity 10a.

[0055] After the cleaning process is completed, the user can stop the rotation of the inner tub 12, then remove the connection relationship between the limiting fit part 3121 of the brush handle 312 and the limiting part 20a2 of the mounting area 20a, take out the cleaning piece 30 from the mounting hole 20a1, and complete the cleaning work of the gap cavity 10a. The cavity wall cleaning scheme of the gap cavity 10a provided in the embodiment can clean without disassembling the inner tub 12, which greatly improves the use convenience of the laundry treatment device 100. In the running state of the device, the inner tub 12 can rotate relative to the cleaning brush 32 to effectively remove the dirt on the cavity wall of the gap cavity 10a, and ensure the hygiene of the laundry cleaning.

[0056] In some embodiments, the cleaning brush 32 is connected to both sides of the brush rod 311 away from the first direction AA, and in the state that the brush handle 312 is connected to the mounting area 20a, the cleaning brush 32 on either side can contact the cavity wall of the gap cavity 10a. Since the cleaning brush 32 needs to be rotated after being inserted into the mounting hole 20a1 to contact the cavity wall of the gap cavity 10a, if the cleaning brush 32 is arranged on both sides of the brush rod 311, the user can rotate clockwise or counterclockwise after inserting the brush rod 311 into the mounting hole 20a1, so that the cleaning brush 32 can quickly and tightly abut against the cavity wall of the gap cavity 10a, thereby improving the flexibility of operation.

[0057] Specifically, the cleaning brush 32 includes a plurality of brush tufts arranged in a rectangular array, and the brush tufts are arranged through the brush rod 311 and extend from both sides of the brush rod 311 away from each other. The brush tufts can be plastic hard bristles, nylon bristles, or metal wire bristles.

[0058] In some embodiments, the transverse cross section of the brush rod 311 is quadrangular, and the cleaning brush 32 is connected to both sides of the brush rod 311 away from the first direction AA. The quadrangular transverse cross section design makes the brush rod 311 more stable when rotating, thereby improving the contact efficiency of the cleaning brush 32 with the cavity wall of the gap cavity 10a, enhancing the cleaning effect, and improving the flexibility of operation. After the brush rod 311 is inserted into the second mounting hole 20a1, the user can rotate clockwise or counterclockwise, so that the cleaning brush 32 can quickly and tightly abut against the outer peripheral wall of the inner tub 12.

[0059] In other embodiments, the brush rod 311 can be circular, semicircular, triangular, pentagonal, or any other polygonal shape, including but not limited to square, rectangular, hexagonal, heptagonal, etc. In addition, the cross section of the brush rod 311 can also be irregular, which is not limited in the present application.

[0060] Please continue to refer to Figure 6 and Figure 7 In some embodiments, the portion of the brush rod 311 between the cleaning brush 32 and the brush handle 312 is formed as a clearance section 3111, and the clearance section 3111 is located in the mounting hole 20a1. When the cleaning member 30 is assembled to the clearance section 3111 located in the mounting hole 20a1, the rotation operation can be performed, the contact and scratching of the cleaning brush 32 with the hole wall of the mounting hole 20a1 during installation and operation are reduced, thereby protecting the integrity of the cleaning brush 32 and prolonging the service life thereof.

[0061] And, the two surfaces of the brush rod 311 along the radial direction of the inner barrel 12 are in clearance fit with the two hole walls of the mounting hole 20a1 along the radial direction of the inner barrel 12. Since the mounting hole 20a1 is long and narrow, that is, the mounting hole 20a1 has a first aspect and a width direction, the width direction can be in the same direction as a certain radial direction of the inner barrel 12, and the width direction of the mounting hole 20a1 is slightly larger than the two surfaces of the brush rod 311, so that the brush rod 311 can rotate smoothly in the mounting hole 20a1. The smooth rotation of the brush rod 311 and the precise fit improve the cleaning efficiency, so that the cleaning brush 32 can be adjusted to the appropriate position faster, and the cleaning preparation time is reduced.

[0062] To further improve the efficiency of the cleaning member 30 in cleaning the cavity wall of the gap cavity 10a, the mounting area 20a can be provided in plurality, and the plurality of mounting areas 20a are uniformly arranged on the end cover assembly. The plurality of cleaning members 30 are connected to the mounting areas 20a one by one, and the plurality of cleaning members 30 work simultaneously, which can shorten the time of single cleaning and improve the efficiency of cleaning the cavity wall of the gap cavity 10a.

[0063] The cleaning member 30 provided by the embodiment can not only clean the outer peripheral wall of the inner barrel 12, but also clean the inner peripheral wall of the outer barrel 11. The specific implementation can be referred to the following embodiments.

[0064] In an embodiment, the cover structure 20 includes a barrel cover 21, which is annular, arranged on the outer barrel 11, specifically on the opening of the outer barrel 11, and has a mounting area 20a. The mounting hole 20a1 is arranged along the second direction BB, that is, the circumferential direction of the barrel cover 21, which can avoid opening a hole with a large radial size on the barrel cover 21, reduce the weakening of the radial strength of the barrel cover 21, and reduce the risk of cracking of the barrel cover 21.

[0065] In the first position, the brush rod 311 of the cleaning member 30 is inserted into the mounting hole 20a1. When inserted, the free end of the cleaning brush 32 is in the same direction as the extension direction of the mounting hole 20a1, so that the brush rod 311 and the cleaning brush 32 easily and smoothly pass through the mounting hole 20a1. After being inserted, the user rotates the brush handle 312 or the brush rod 311 to drive the cleaning brush 32 to abut against the outer peripheral wall of the inner barrel 12. When the cleaning brush 32 reaches the cleaning state, the brush handle 312 can be connected with the mounting area 20a of the barrel cover 21 to position the cleaning member 30 at the position where the cleaning brush 32 contacts the outer peripheral wall of the inner barrel 12. During the cleaning process, the user can start the rotation of the inner barrel 12 relative to the outer barrel 11. Since the cleaning member 30 is positioned on the barrel cover 21, the inner barrel 12 rotates relative to the cleaning member 30. During the rotation, the cleaning brush 32 brushes the outer peripheral wall of the inner barrel 12.

[0066] In an embodiment, the cover structure 20 comprises a balance ring (not shown) arranged on the inner tub 12 and having a mounting area 20a, the balance ring having a mounting hole 20a1 communicating with the gap cavity 10a, the mounting hole 20a1 being used for inserting the cleaning member 30, the mounting hole 20a1 being long and extending along the circumference of the balance ring, which can avoid opening a large radial hole on the balance ring, reduce the weakening of the radial strength of the balance ring, and reduce the risk of cracking of the balance ring.

[0067] For the specific cooperation between the cleaning member 30 and the mounting area 20a of the balance ring, reference can be made to the cooperation between the cleaning member 30 and the mounting area 20a of the tub cover 21, which will not be described here again. In the second position, the brush handle 312 is connected to the balance ring to position the cleaning member 30 at a position where the cleaning brush 32 contacts the inner circumferential wall of the outer tub 11. The user can rotate the inner tub 12 relative to the outer tub 11 by starting, and since the cleaning member 30 is positioned on the balance ring, the balance ring will rotate with the inner tub 12, and in the process of rotation, the inner circumferential wall of the outer tub 11 is brushed.

[0068] In an embodiment, the mounting area 20a comprises a first mounting area 20a and a second mounting area 20a, the tub cover 21 has the first mounting area 20a, and the balance ring has the second mounting area 20a, wherein the cleaning member 30 can be selectively connected to the first mounting area 20a or the second mounting area 20a. Understandably, in the case of only one cleaning member 30, the user can adjust the position of the cleaning member 30 to clean the outer circumferential wall of the inner tub 12 or the inner circumferential wall of the outer tub 11. It should be noted that the length of the brush rod 311 away from the two cleaning brushes 32 can not be the same, which corresponds to the appropriate length for cleaning the outer circumferential wall of the inner tub 12 and the inner circumferential wall of the outer tub 11, respectively. The appropriate length of the cleaning brush 32 can be marked on the end surface of the brush handle 312 away from the brush rod 311, so that the user can rotate the cleaning brush 32 of the appropriate length to abut the outer tub 11 or the inner tub 12 according to the needs.

[0069] In a second aspect, the application also provides a cleaning control device of a laundry treatment apparatus 100, which is applied to the laundry treatment apparatus 100 in any of the above embodiments. The cleaning control device comprises a receiving module and a control module arranged in the laundry treatment apparatus 100. The receiving module is used to obtain a cleaning instruction and transmit a cleaning start signal to the control module. Specifically, after the cleaning member 30 is arranged in place, the user can click the cleaning tub program on the panel of the laundry treatment apparatus 100 to trigger the cleaning instruction.

[0070] After the cleaning tub program is started, the one-way valve arranged on the drain pipe of the laundry treatment apparatus 100 is closed, and the control module is used to control the water inlet pipe of the laundry treatment apparatus 100 to inlet water. In response to the water level reaching the full water level, the control module controls the water inlet pipe to stop inletting water. After the water inlet pipe inlets water to the full water level, the inner tub will be soaked for 15 minutes to soften and loosen the dirt on the tub wall.

[0071] Further, the control module controls the inner tub 12 to rotate at a cleaning rotation speed, which can be intermittent rotation, i.e., the inner tub 12 rotates for 2 seconds and then stops for 2 seconds, and the cycle is repeated for slow cleaning. The inner tub 12 stops rotating in response to a first time length, which can be 15 minutes. After the inner tub 12 stops rotating, it is soaked again for 10 minutes to further decompose and remove residual dirt. After the soaking time length is reached, the control module controls the inner tub 12 to again repeat the above stages, i.e., to rotate at the cleaning rotation speed, and the first time length for the second rotation of the inner tub 12 can be 20 minutes.

[0072] Finally, the drain of the clothes treatment apparatus 100 is controlled, specifically, a one-way valve on the drain is opened to communicate with the outside, and in response to completion of the draining, the inner tub 12 is controlled to spin at a target rotation speed, which is a high-speed rotation speed of the inner tub 12 in a spin program, and the inner tub 12 is controlled to stop rotating in response to a second time length, which can be 5 minutes. The water after cleaning the tub wall is drained through the drain, achieving the purpose of simple and fast tub cleaning, and ensuring drying of the tub assembly 10 to prevent bacterial growth.

[0073] It should be noted that the above cleaning rotation speed, soaking time length, first time length, and second time length can be set according to the user's own preferences.
