Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of clothes processing equipment, in particular to an inner drum assembly and clothes processing equipment. BACKGROUND

[0002] The washing tub of the traditional drum washing machine is composed of an outer drum and an inner drum, and a series of holes are opened on the inner drum for water inlet and drainage. The clothes are tumbled and washed in the inner drum, but the water for washing not only exists in the inner drum, but also a large part exists in the outer drum, and the water inside and outside the inner drum can flow freely through the small holes on the inner drum.

[0003] After the washing machine is used for a long time, part of the dirt may not completely flow away with the drainage system, but remains between the outer drum and the inner drum. Since the drum washing machine is difficult to disassemble, the dirt between the inner and outer drums cannot be disassembled and cleaned by non-professionals, so that the dirt in the outer drum gradually accumulates. Since the washing water can freely enter and exit the inner drum, the dirt in the outer drum repeatedly contaminates the clothes in the subsequent washing, causing cross contamination between the front and the back.

[0004] At the same time, in the traditional washing machine, the water between the outer drum and the inner drum does not actually participate in the washing, and the water needs to fill the bottom of the outer drum before reaching the inner drum to participate in the washing, which causes double waste of water and detergent.

[0095] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the technical solutions provided by the present application. However, it will be apparent to one of ordinary skill in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0096] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise. In addition, it should be understood that when the terms "comprise" and / or "include" are used in the specification, it means that the stated features, integers, steps, operations, elements, and / or components exist, but not excluding the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0097] Exemplary embodiments according to the present application will now be described in greater detail below with reference to the accompanying drawings. These exemplary embodiments may, however, be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that the exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0098] As shown in Figures 1 to 4 A first aspect according to an embodiment of the present application provides an inner drum assembly 100, comprising: an inner drum body 110, the inner drum body 110 comprising a drum wall 111, the drum wall 111 forming a draining area and an isolation area along a length direction; and a plurality of draining holes 120, the plurality of draining holes 120 being arranged on the inner drum body 110 and only arranged in the draining area.

[0099] The inner drum assembly 100 provided by the embodiment of the present application comprises the inner drum body 110 and the plurality of draining holes 120, and the inner drum body 110 comprises the drum wall 111, the drum wall 111 forming the draining area and the isolation area along the length direction, and the plurality of draining holes 120 are only arranged in the draining area, that is, the isolation area is not arranged with the plurality of draining holes 120. Based on this, in the use process of the inner drum assembly 100, the drum wall 111 encloses to form a containing space, the containing space is used for containing clothes to be treated, and the inner drum body 110 can have a sealed relationship with an outer drum assembly 210 of a clothes treatment device. Based on this, the outer drum assembly 210 and the draining area of the inner drum assembly 100 can enclose to form a draining space 290, and the isolation area of the outer drum assembly 210 and the inner drum assembly 100 can enclose to form a liquid-free space 280. Based on this, when the clothes are treated by the inner drum assembly 100, due to the formation of the draining area and the isolation area, only part of the liquid is stored in the draining space 290 through the plurality of draining holes 120, and the isolation area is not arranged with the plurality of draining holes 120. Therefore, the liquid in the inner drum assembly 100 will not enter the liquid-free space. Based on this, in the first aspect, only the water in the draining space 290 needs to be drained, so as to avoid the backflow of sewage into the inner drum body 110, reduce the probability that the dirty in the outer drum assembly 210 contaminates the clothes in the washing process, reduce or eliminate cross infection, and ensure the hygiene of the clothes treatment. On the other hand, during the washing process, the washing liquid will not enter the liquid-free space 280, and therefore the liquid-free space 280 needs to be filled with the washing liquid. Only the draining space 290 needs to be filled with the washing liquid, so as to treat the clothes by the inner drum body 110, which can reduce the amount of water and detergent, and is more energy-saving and environmentally friendly.

[0100] It can be understood that, by the inner drum assembly 100 provided by the embodiments of the present application, when the treatment of the clothes is completed and the liquid is discharged, the liquid can be discharged out of the inner drum body 110 under the action of the centrifugal force through the rotation of the inner drum body 110. When the inner drum assembly 100 is applied to the clothes treatment device, under the action of the rotation of the inner drum assembly 100, the liquid in the inner drum assembly 100 can be discharged into the liquid discharge area between the inner drum assembly 100 and the outer drum assembly 210 through the liquid discharge hole 120, and then be discharged.

[0101] It can be understood that, in order to further reduce the probability of the residual liquid between the outer drum assembly 210 and the inner drum assembly 100 flowing back into the inner drum body 110, the number of the liquid discharge holes 120 can be reduced as much as possible under the premise of ensuring the liquid discharge efficiency. For example, the inner drum assembly 100 can be in a cylindrical shape, and the liquid discharge holes 120 can be arranged in a single row or multiple rows along the outer periphery of the cylindrical shape. The number of the rows of the liquid discharge holes 120 can be reduced as much as possible under the premise of ensuring the liquid discharge efficiency.

[0102] As shown in FIG. 1, in a possible implementation, the length of the liquid discharge area along the length direction of the drum wall 111 is 1 cm to 20 cm. Figure 4

[0103] In the technical solution, the specific parameters of the liquid discharge area are further provided. The length of the liquid discharge area can be 1 cm to 20 cm, that is, the liquid discharge holes 120 are arranged in the length direction of the drum wall 111 within 1 cm to 20 cm. The other areas of the drum wall 111 are the isolation areas, and the liquid discharge holes 120 do not need to be arranged in the other areas. Most of the area of the inner drum body 110 can be the isolation area. When the inner drum assembly 100 is applied to the clothes treatment device, most of the area between the inner drum assembly 100 and the outer drum assembly 210 is the liquid-free space 280. The residual amount of the liquid between the inner drum assembly 100 and the outer drum assembly 210 can be further reduced, the amount of the liquid used can be further reduced, and the clothes treatment can be more hygienic and water-saving.

[0104] As shown in FIG. 1, in a possible implementation, the liquid discharge area and the isolation area are arranged adjacent to each other. The ratio of the length of the liquid discharge area to the length of the isolation area along the length direction of the drum wall 111 is 0.1 to 0.4. Figure 4

[0105] ​​In the technical solution, the relationship between the drainage area and the isolation area is further provided, and the ratio of the length of the drainage area to the length of the isolation area along the length direction of the cylinder wall 111 is 0.1 to 0.4, that is, most of the area of the inner cylinder body 110 is the isolation area, and a small part of the area is the drainage area. When the inner cylinder assembly 100 is applied to the laundry treatment device, most of the area between the inner cylinder assembly 100 and the outer cylinder assembly 210 is the liquid-free space 280, which can further reduce the amount of liquid remaining in the inner cylinder assembly 100 and the outer cylinder assembly 210, further reduce the amount of liquid used, and make the laundry treatment more sanitary and water-saving.

[0106] As shown in Figures 1 to 2 In a possible implementation, the inner cylinder assembly 100 further comprises a partition 130 connected to the inner cylinder body 110 and arranged at the connection between the drainage area and the isolation area and covering at least part of the drainage area.

[0107] In the technical solution, the structure of the inner cylinder assembly 100 is further provided. The inner cylinder assembly 100 can comprise a partition 130 connected to the inner cylinder body 110 and arranged at the connection between the drainage area and the isolation area, that is, the partition 130 can separate the cylinder wall 111 of the inner cylinder body 110 into the drainage area and the isolation area. Based on this, during use of the inner cylinder assembly 100, the partition 130 can abut and seal with the outer cylinder assembly 210 of the laundry treatment device or the components above the outer cylinder assembly 210. During rotation of the inner cylinder assembly 100, the partition 130 plays a supporting and sealing role. In this way, in the first aspect, the inner cylinder assembly 100 and the outer cylinder assembly 210 are conveniently enclosed to form the liquid-free space 280 and the drainage space 290, which can reduce the amount of liquid remaining. In the second aspect, the main friction force point of the inner cylinder assembly 100 is established on the partition 130, which reduces the wear of the inner cylinder body 110 and reduces the probability of deformation of the inner cylinder assembly 100, thereby ensuring the service life of the inner cylinder assembly 100.

[0108] In the technical solution, considering that the partition 130 needs to have a certain width to have a more excellent sealing effect, and the mechanical strength of the drainage area is slightly lower than that of the isolation area due to the drainage hole 120, the partition 130 can cover part of the drainage area, which can improve the sealing effect and further reduce the probability of deformation of the inner cylinder body 110. Further, generally, in order to facilitate the preparation and assembly of the inner cylinder assembly 100, the drainage area is usually formed at the end of the inner cylinder body 110. Covering part of the drainage area by the partition 130 also facilitates the assembly of the partition 130.

[0109] As shown in Figures 1 to 2As shown in the figure, in a possible implementation, the partition 130 comprises: a first sealing member 131, the first sealing member 131 is sleeved on the inner cylinder body 110; and an avoiding opening 132, the avoiding opening 132 is arranged on the first sealing member 131 to avoid the liquid discharge hole 120.

[0110] In the technical scheme, the structure of the partition 130 is further provided, the partition 130 can comprise the first sealing member 131 and the avoiding opening 132, the first sealing member 131 is sleeved on the inner cylinder body 110, and the first sealing member 131 is abutted against the outer cylinder assembly 210 or the component above the outer cylinder assembly 210, so that the liquid-free space 280 and the liquid discharge space 290 are enclosed between the inner cylinder assembly 100 and the outer cylinder assembly 210, and the rotation of the inner cylinder assembly 100 relative to the outer cylinder assembly 210 is facilitated.

[0111] In the technical scheme, the avoiding opening 132 is arranged on the first sealing member 131, the avoiding opening 132 can avoid the liquid discharge hole 120, liquid in the inner cylinder body 110 is discharged through the liquid discharge hole 120, and especially, the laundry in the inner cylinder assembly 100 is facilitated to be treated by the spin-drying.

[0112] As shown in the figure, Figures 1 to 2 In a possible implementation, the liquid discharge area further comprises a mounting portion, and the first sealing member 131 is connected to the inner cylinder body 110 through the mounting portion.

[0113] In the technical scheme, in order to facilitate the assembly of the first sealing member 131, the liquid discharge area further comprises a mounting portion, and the first sealing member 131 is connected to the inner cylinder body 110 through the mounting portion, so that the fixing strength of the first sealing member 131 is improved, and the assembly of the first sealing member 131 is facilitated.

[0114] In some examples, the mounting portion can comprise a threaded hole formed on the liquid discharge area.

[0115] In some examples, in order to guarantee the sealing effect of the first sealing member 131, one side of the first sealing member 131 towards the inner cylinder body 110 can be provided with a sealing layer 1311, and the sealing layer 1311 can be made of rubber material.

[0116] As shown in the figure, Figure 3 In a possible implementation, the inner cylinder body 110 further comprises: a cylinder bottom 112, the cylinder wall 111 is connected to the cylinder bottom 112, and the liquid discharge hole 120 is arranged close to the cylinder bottom 112.

[0117] In the technical solution, the inner cylinder body 110 can further include a cylinder bottom 112 connected with the cylinder wall 111, and the cylinder bottom 112 and the cylinder wall 111 can enclose a containing space for containing clothes.

[0118] In the technical solution, the liquid discharge hole 120 is arranged close to the cylinder bottom 112. In this way, on the one hand, the mechanical strength of the inner cylinder body 110 close to one end of the cylinder bottom 112 is higher, and the liquid discharge hole 120 can be conveniently arranged on the end of the cylinder wall 111 close to the cylinder bottom 112, which can guarantee the mechanical strength of the inner cylinder body 110 and facilitate the arrangement of the liquid discharge hole 120; on the other hand, when the clothes in the inner cylinder assembly 100 are dehydrated, the liquid in the inner cylinder assembly 100 can be conveniently collected towards the liquid discharge hole 120 when the inner cylinder assembly 100 rotates, which can improve the liquid discharge efficiency; and on the third hand, the liquid discharge area is arranged on the end of the cylinder wall 111 close to the cylinder bottom 112, so that the liquid discharge space 290 enclosed between the inner cylinder assembly 100 and the outer cylinder assembly 210 is also close to the end of the inner cylinder assembly 100 or the clothes treatment device, which facilitates the discharge of the liquid through the clothes treatment device.

[0119] As shown in Figure 3 In a possible implementation, the inner cylinder assembly 100 further includes a gas discharge hole 140 arranged on the cylinder bottom 112, and the gas discharge hole 140 is arranged in a middle region of the cylinder bottom 112.

[0120] In the technical solution, considering some use scenarios and requirements, the clothes can be dried by the clothes treatment device, and the gas discharge hole 140 is arranged to facilitate the discharge of water vapor.

[0121] It can be understood that the gas discharge hole 140 is arranged in the middle region of the cylinder bottom 112, that is, the height of the arrangement position of the gas discharge hole 140 can be higher than the preset height of the liquid level in the inner cylinder body 110. Based on this, when the clothes are treated by the inner cylinder assembly 100, the liquid will not overflow through the gas discharge hole 140, which improves the user experience.

[0122] In a possible implementation, the inner cylinder body 110 is in a cylindrical shape. In this way, the production and processing of the inner cylinder body 110 are facilitated, and the cost can be reduced.

[0123] In a possible implementation, the inner cylinder body 110 is in a circular truncated cone shape, and the liquid discharge hole 120 is arranged at the flared end of the circular truncated cone-shaped inner cylinder body 110. In this way, by designing the inner cylinder body 110 as a circular truncated cone shape, more liquid can be collected in the liquid discharge area of the inner cylinder body 110 when the clothes in the inner cylinder body 110 are dehydrated, which facilitates rapid and thorough dehydration of the clothes.

[0124] As shown inFigure 2 As shown, in one feasible embodiment, the inner cylinder assembly 100 further includes a retainer 150, which is connected to the cylinder wall 111 and arranged at the end of the inner cylinder body 110.

[0125] In this technical solution, the inner cylinder assembly 100 may also include a retainer 150, which is connected to the cylinder wall 111 of the inner cylinder body 110. The retainer 150 can serve to form the inner cylinder body 110 and reduce the probability of deformation of the inner cylinder body 110.

[0126] like Figure 1 As shown, in one possible embodiment, the inner cylinder assembly 100 further includes a second seal 160 disposed between the retainer 150 and the cylinder wall 111.

[0127] In this technical solution, in order to ensure the sealing effect, a second sealing element 160 can be provided between the retainer 150 and the cylinder wall 111.

[0130] In this technical solution, a further arrangement of the retainer 150 is provided, in which a groove 113 is formed at the open end of the inner cylinder body 110, and the retainer 150 is recessed in the groove 113. Based on this, the retainer 150 and the inner cylinder body 110 can have three contact surfaces, which can improve the support effect of the retainer 150 on the inner cylinder body 110.

[0131] In the technical solution, the inner cylinder assembly 100 further comprises a first fastener 180, which is connected to the retainer 150 through the first wall surface 114, so that the fixation of the retainer 150 is more reliable.

[0132] In the technical solution, the second sealing member 160 is arranged between the second wall surface 115 and the retainer 150, so that the sealing relationship between the second wall surface 115 and the retainer 150 is guaranteed, and the probability of liquid overflow is reduced.

[0133] In the technical solution, the retainer 150 is formed with a finished surface 151 on the side facing the groove bottom of the sink 113, so that the wear of the retainer 150 and the inner cylinder body 110 is reduced.

[0134] As shown in Figures 1 to 13 According to the second aspect of the embodiments of the present application, a laundry treating apparatus is provided, which comprises the inner cylinder assembly 100 according to any one of the above technical solutions.

[0135] The laundry treating apparatus provided by the embodiments of the present application comprises the inner cylinder assembly 100 according to any one of the above technical solutions, so that the laundry treating apparatus has all the beneficial effects of the inner cylinder assembly 100 according to the above technical solutions, which will not be described herein.

[0136] As shown in Figures 5 to 8 As shown in Figure 8 The area formed by the large squares is the liquid discharge space 290, and the area formed by the small squares is the liquid-free space 280. In an available embodiment, the laundry treating apparatus further comprises an outer cylinder assembly 210, and the inner cylinder assembly 100 is arranged in the outer cylinder assembly 210; and a partition assembly 220, which is connected to the outer cylinder assembly 210; wherein the partition assembly 220, the inner wall of the outer cylinder assembly 210, and the isolation area of the inner cylinder assembly 100 enclose the liquid-free space 280; and wherein the partition assembly 220, the inner wall of the outer cylinder assembly 210, and the liquid discharge area of the inner cylinder assembly 100 enclose the liquid discharge space 290.

[0137] In the technical solution, the structure of the laundry treating apparatus is further provided. The laundry treating apparatus comprises the outer cylinder assembly 210 and the partition assembly 220. Based on this, the inner cylinder assembly 100 is arranged in the outer cylinder assembly 210, and the partition assembly 220 is connected to the outer cylinder assembly 210, which also supports the inner cylinder assembly 100. When the laundry treating apparatus is used to treat the laundry, the laundry is arranged in the containing space in the inner cylinder body 110, and then water and detergent are injected into the inner cylinder body 110, so that the laundry is cleaned by the movement of the inner cylinder body 110.

[0138] In the technical solution, when the inner cylinder assembly 100 is assembled into the outer cylinder assembly 210, the isolation assembly 220 is in contact and sealed with the inner cylinder body 110, and based on this, the isolation assembly 220, the inner cylinder assembly 100 and the outer cylinder assembly 210 can enclose two spaces, wherein the space enclosed by the liquid discharge area of the cylinder wall 111 is the liquid discharge space 290, and the space enclosed by the isolation area of the cylinder wall 111 is the liquid-free space 280. The liquid discharge hole 120 opened in the liquid discharge area is communicated to the liquid discharge space 290, and when the laundry is washed by the laundry treatment equipment, only a small amount of water is needed to fill the liquid discharge space 290 due to the formation of the liquid-free space 280, so that the laundry can be washed, and the laundry treatment equipment can be more water-saving. When the laundry treatment equipment is dehydrated, the inner cylinder body 110 can be controlled to rotate, and the liquid in the inner cylinder body 110 can enter the liquid discharge space 290 through the liquid discharge hole 120 under the action of centrifugal force, and then be discharged outside the laundry treatment equipment. Due to the formation of the liquid-free space 280, the amount of residual liquid is reduced, and the laundry treatment equipment is more hygienic when washing the laundry.

[0139] As shown in Figure 5 and Figure 9 in an available embodiment, the isolation assembly 220 includes a third sealing member 221 connected to the outer cylinder assembly 210, and the third sealing member 221 is used to abut and seal with the partition 130 of the inner cylinder assembly 100.

[0140] In the technical solution, the structure of the isolation assembly 220 is further provided, and the isolation assembly 220 can include a third sealing member 221, which abuts and seals with the partition 130, so that the space enclosed between the inner cylinder assembly 100 and the outer cylinder assembly 210 is divided into the liquid-free space 280 and the liquid discharge space 290. The liquid only needs to fill the liquid discharge space 290 to be washed, which is more water-saving, and at the same time, when the laundry treatment equipment is dehydrated, the laundry treatment equipment can drain water more completely and reduce the amount of residual liquid.

[0141] As shown in Figure 11 in some examples, a limiting member 2121 can be further formed on the second cylinder body 212, and the third sealing member 221 is connected to the limiting member 2121, which can inhibit the movement of the third sealing member 221, so that the fixing of the third sealing member 221 is more reliable.

[0142] As shown in Figure 5 , Figure 9 and Figure 11As shown in the figure, in a feasible implementation, the insulation assembly 220 comprises a door seal assembly 222 connected to the outer drum assembly 210, and the door seal assembly 222 is used for abutting sealing with the retainer 150 of the inner drum assembly 100.

[0143] In the technical solution, the structure of the insulation assembly 220 is further provided, and the insulation assembly 220 can further comprise the door seal assembly 222, which is mainly used for sealing the opening end side of the inner drum body 110. The abutting sealing of the door seal assembly 222 with the retainer 150 can prevent the liquid from entering the gap between the inner drum assembly 100 and the outer drum assembly 210 through the opening end of the inner drum assembly 100, and can further reduce the residual amount of liquid between the inner drum assembly 100 and the outer drum assembly 210.

[0144] As shown in the figure, Figure 5 , Figure 9 and Figure 12 in a feasible implementation, the door seal assembly 222 comprises a door seal body 2221 connected to the end of the outer drum assembly 210, a liquid injection port provided on the door seal body 2221 and leading to the containing space in the inner drum assembly 100, and a reinforcing ring 2223 arranged in the door seal body 2221 and sleeved on the inner drum assembly 100.

[0145] In the technical solution, the structure of the door seal assembly 222 is further provided, and the door seal assembly 222 can comprise the door seal body 2221, the liquid injection port, and the reinforcing ring 2223. The door seal body 2221 is connected to the outer drum assembly 210. The liquid injection port is provided to facilitate the injection of water and detergent for washing clothes into the inner drum assembly 100, and the use of the clothes treatment device is more convenient.

[0146] In some examples, a drying duct air outlet 2222 can be further formed on the door seal assembly 222 and lead to the inner drum body. The liquid injection port is formed on the door seal assembly 222 to avoid the upper region of the drying duct air outlet 2222. Such arrangement facilitates the sealing of the liquid injection port. The specific style of the liquid injection port can comprise a water inlet or a nozzle.

[0147] In the technical solution, the door seal assembly 222 is located on one side of the opening end of the inner drum assembly 100, and the mechanical strength of the inner drum assembly 100 at this position is weak. Therefore, the reinforcing ring 2223 can be arranged in the door seal assembly 222, and the door seal assembly 222 is sleeved on the inner drum assembly 100, which can reduce the probability of deformation of the door seal assembly 222, and further can include the inner drum assembly 100, especially reduce the probability of deformation of the inner drum body 110.

[0148] As shown in the figure, Figure 5As shown, in one feasible embodiment, the garment processing device further includes: a housing 230, with an outer cylinder assembly 210 disposed within the housing 230; a first drain pipe 240, which connects to a drain space 290; wherein, the door seal assembly 222 further includes: a drain channel 2224 and a second drain pipe 2225, the drain channel 2224 being formed at the bottom of the door seal body 2221 and connecting to the accommodating space within the inner cylinder assembly 100, one end of the second drain pipe 2225 being connected to the drain channel 2224 and the other end being connected to the first drain pipe 240.

[0149] In this technical solution, the garment processing equipment may also include a housing 230 and a first drain pipe 240.

The liquid in the drain space 290 can be discharged simply by opening the first drain pipe 240, which facilitates the dehydration process of the garment processing equipment and can further reduce the amount of liquid remaining in the garment processing equipment.

[0150] In this technical solution, considering that the cleaning liquid and detergent can be injected into the inner drum assembly 100 through the door seal assembly 222, the liquid will accumulate in the door seal assembly 222 and the inner drum assembly 100. Based on this, a drain channel 2224 can be formed on the door seal body 2221, and the drain channel 2224 and the first drain pipe 240 can be connected through the second drain pipe 2225 to drain the liquid accumulated in the door seal assembly 222, thereby further reducing the amount of liquid remaining in the clothing processing equipment.

[0151] like Figure 5 , Figure 9 and Figure 12 As shown, in some examples, the door seal assembly 222 may also include a plug pipe 2226, one end of which is connected to the drain channel 2224 and the other end is connected to the second drain pipe 2225. This arrangement facilitates the assembly of the second drain pipe 2225.

[0152] In one feasible implementation, the outer cylinder assembly 210 includes: a first cylinder 211 and a second cylinder 212, wherein the first cylinder 211 is connected to the second cylinder 212; wherein, the outer surface of the first cylinder 211 is formed with a mounting surface 2111, and the door seal body 2221 of the insulating assembly 220 is fitted onto the first cylinder 211 through the mounting surface 2111.

[0153] In the technical solution, the structure of the outer cylinder assembly 210 is further provided, and the outer cylinder assembly 210 can include a first cylinder body 211 and a second cylinder body 212. In this way, the inner cylinder assembly 100 can be arranged in the outer cylinder assembly 210. For example, during assembly, the inner cylinder assembly 100 is arranged in one of the first cylinder body 211 or the second cylinder body 212, and then the first cylinder body 211 and the second cylinder body 212 are connected, so that the inner cylinder assembly 100 is encapsulated in the outer cylinder assembly 210, facilitating the assembly of the clothes processing device.

[0154] In the technical solution, the outer surface of the first cylinder body 211 is formed with an assembly surface 2111, and the door sealing body 2221 of the insulation assembly 220 is sleeved on the first cylinder body 211 through the assembly surface 2111. In this way, the connection between the insulation assembly 220 and the first cylinder body 211 is more reliable, and the probability of loosening of the insulation assembly 220 is reduced.

[0155] In some examples, the assembly surface 2111 can include a rough surface formed on the first cylinder body 211 or a clamping groove formed on the first cylinder body 211, or other structures that can increase the fixing strength of the insulation assembly 220.

[0156] As shown in FIG. 1, Figure 5 In a feasible implementation, the clothes processing device further includes a door body 250 connected to the outer cylinder assembly 210, and a driving assembly 260 connected to the inner cylinder assembly 100 and configured to drive the inner cylinder assembly 100 to rotate.

[0157] In the technical solution, the clothes processing device can further include the door body 250, which facilitates sealing of the clothes processing device.

[0158] In the technical solution, the clothes processing device can further include the driving assembly 260, which is connected to the inner cylinder assembly 100 and facilitates driving the inner cylinder assembly 100 to rotate. By controlling the rotation speed of the inner cylinder assembly 100, the clothes processing device can control the cleaning or dehydration of clothes.

[0159] As shown in FIG. 1, Figure 5 and Figure 6 In a feasible implementation, the driving assembly 260 includes a driving member 261, and a flange plate 262 connected to the output end of the driving member 261 and connected to the inner cylinder assembly 100. The second fastener 270 passes through the cylinder wall 111 and the partition 130 of the inner cylinder assembly 100 and is connected to the flange plate 262.

[0160] In the technical solution, the structure of the driving assembly 260 is further provided, and the driving assembly 260 can include a driving member 261 and a flange plate 262. The flange plate 262 is connected to the inner drum assembly 100. The opening driving member 261 drives the flange plate 262 to rotate, and the flange plate 262 drives the inner drum assembly 100 to rotate.

[0161] In the technical solution, the connection mode of the flange plate 262 is further provided. The second fastener 270 passes through the drum wall 111 and the partition 130 and is connected to the flange plate 262. The flange plate 262 is connected between the partitions, so that the flange plate 262, the inner drum body 110 and the partitions can rotate synchronously, and the probability of misalignment of the partitions can be reduced, thereby ensuring the reliability of the clothes treatment equipment.

[0162] As shown in Figure 13 In an available implementation, the clothes treatment equipment further includes a rotating shaft 2110 arranged above the inner drum body 110, and a sealing band 2120 sleeved on the rotating shaft 2110 and the inner drum body 110, the sealing band 2120 being configured to cover the liquid discharge hole 120 below the inner drum body 110.

[0163] In the technical solution, the style of the isolation assembly 220 is further provided. The isolation assembly 220 can include the rotating shaft 2110 and the sealing band 2120. The sealing band 2120 is sleeved on the inner drum body 110. When the inner drum body 110 rotates, the sealing band 2120 rotates synchronously with the inner drum body 110. Through the arrangement of the sealing band 2120, the sealing band 2120 can always cover the liquid discharge hole 120 at the bottom of the inner drum body 110. Based on this, even if a part of liquid remains between the inner drum body 110 and the outer drum assembly 210, the liquid cannot enter the inner drum body 110 through the liquid discharge hole 120, so that the clothes treatment equipment can treat clothes more hygienically. Meanwhile, when the clothes are washed by the clothes treatment equipment, liquid is injected into the inner drum assembly 100. Since the liquid discharge hole 120 at the bottom of the inner drum body 110 is covered, the liquid injected into the inner drum body 110 will not flow into the gap between the outer drum assembly 210 and the inner drum assembly 100. Only the liquid level requirement of the inner drum body 110 needs to be met to perform washing, which is more water-saving.

[0164] It can be understood that when the isolation assembly 220 includes the sealing band 2120 and the rotating shaft 2110, the inner drum body 110 can be driven to rotate by the driving assembly when the clothes need to be dehydrated. The liquid in the inner drum body 110 can be discharged out of the inner drum assembly 100 through the liquid discharge hole 120 at the top of the inner drum body 110 under the action of centrifugal force.

[0165] The laundry processing device provided by the embodiment of the present application, when the driving member 261 is turned on, the driving member 261 drives the flange plate 262 to rotate, the flange plate 262 drives the inner drum main body 110, the partition piece 130, the retainer 150 and the second sealing piece 160 to rotate, the laundry is arranged in the inner drum main body 110, water and detergent for cleaning are injected into the inner drum assembly 100 through the door seal assembly 222, and the laundry is cleaned through rotation of the inner drum main body 110. The inner drum assembly 100 and the outer drum assembly 210 form a first set of sealing structures through the partition piece 130 and the third sealing piece 221, and form a second set of sealing structures through the door seal assembly 222 and the second sealing piece 160, based on which the drainage space 290 can be enclosed and formed in the drainage area of the outer drum assembly 210 and the inner drum assembly 100, and the liquid-free space 280 can be enclosed and formed between the isolation area of the outer drum assembly 210 and the inner drum assembly 100. Due to the formation of the drainage area and the isolation area, only part of the liquid is stored in the drainage space 290 through the drainage hole 120, and no drainage hole 120 is arranged on the isolation area, so that the liquid in the inner drum assembly 100 cannot enter the liquid-free space. Based on this, on the one hand, the water in the drainage space 290 can be emptied to avoid backflow of sewage into the inner drum main body 110, reduce the probability of contamination of the laundry in the outer drum assembly during washing, and reduce or eliminate cross infection, thereby ensuring the hygiene of the laundry processing; on the other hand, during washing, the liquid for washing cannot enter the liquid-free space 280, so it is also necessary to fill the liquid-free space 280 with washing liquid, and only the liquid for washing is needed to fill the drainage space 290, so that the laundry can be processed by the inner drum main body 110, thereby reducing the amount of water and detergent, and being more energy-saving and environmentally friendly.

[0166] The laundry processing device provided by the embodiment of the present application, during the specific dehydration process, the inner drum main body 110 can be driven to rotate by the driving member 261, under the action of centrifugal force, the liquid in the inner drum main body 110 is discharged to the drainage space 290 through the drainage port, and then discharged to the outside of the laundry processing device through the first drainage pipe 240, and the liquid near the door seal assembly 222 on the open end side of the inner drum assembly 100 can be discharged to the first drainage pipe 240 through the drainage channel 2224 and the second drainage pipe 2225, based on which the laundry can be dehydrated.
