[0044] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided in this application. However, it will be apparent to those skilled in the art that the technical solutions provided in this application can be implemented without one or more of these details.

[0045] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0046] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may 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 these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0047] In related technologies, clothes are tumbled and washed inside the inner drum. However, the washing water exists not only in the inner drum but also a significant portion in the outer drum. Water flows freely between the inner and outer drums through small holes in the inner drum. After prolonged use, some dirt may not be completely flushed away by the drainage system and remains between the outer and inner drums. Because the washing section of a front-loading washing machine is difficult to disassemble, this dirt cannot be cleaned without professional assistance, leading to a gradual accumulation of grime in the outer drum. Since washing water can freely enter and exit the inner drum, dirt from the outer drum repeatedly contaminates the clothes during subsequent washes, causing cross-contamination. Furthermore, in traditional washing machines, the water between the outer and inner drums does not actually participate in the washing process; the water must first fill the bottom of the outer drum before reaching the inner drum, resulting in a double waste of water and detergent.

[0048] As shown in Figures 1 to 4, a first aspect of the present application provides an inner cylinder assembly 100, comprising: an inner cylinder body 110, the inner cylinder body 110 including a cylinder wall 111, the cylinder wall 111 forming a drainage area and an isolation area along the length direction of the cylinder wall 111; and a plurality of drainage holes 120, the plurality of drainage holes 120 being formed on the inner cylinder body 110 and arranged only in the drainage area.

[0049] The inner cylinder assembly 100 provided in this application embodiment includes an inner cylinder body 110 and a plurality of drain holes 120. The inner cylinder body 110 includes a cylinder wall 111, and the cylinder wall 111 forms a drain area and an isolation area along the length direction. The drain holes 120 are only arranged in the drain area, that is, the isolation area is not arranged with drain holes 120. Based on this, during the use of the inner drum assembly 100, a receiving space is formed within the drum wall 111 to hold the clothes to be processed. The inner drum body 110 and the outer drum assembly 210 of the clothing processing equipment can be sealed. Furthermore, the drainage area of ​​the outer drum assembly 210 and the inner drum assembly 100 can enclose a drainage space 290, while a liquid-free space 280 can be formed between the outer drum assembly 210 and the inner drum assembly 100. Therefore, when processing clothes through the inner drum assembly 100, due to the formation of the drainage area and the isolation area, only a portion of the liquid accumulates in the drainage space 290 through the drainage hole 120. No drainage hole 120 is provided in the isolation area. Therefore, the liquid inside the inner drum assembly 100 will not enter the liquid-free space. Based on this, firstly, by simply draining the water from the drain space 290, sewage can be prevented from flowing back into the inner drum body 110, reducing the probability of dirt in the outer drum assembly 210 contaminating the clothes being washed, reducing or eliminating cross-contamination, and ensuring the hygienic condition of the clothes. Secondly, during the washing process, the washing liquid will not enter the liquid-free space 280, so the liquid-free space 280 also needs to be filled with washing liquid. Only the washing liquid needs to fill the drain space 290, and the clothes can be treated through the inner drum body 110, which can reduce the amount of water and detergent used, making it more energy-efficient and environmentally friendly.

[0050] It is understood that, through the inner drum assembly 100 provided in this application embodiment, when the clothing is processed and liquid is drained, the liquid will be discharged outside the inner drum body 110 through the drain hole 120 under the action of centrifugal force due to the rotation of the inner drum body 110. When the inner drum assembly 100 is applied to a clothing processing device, under the action of the rotation of the inner drum assembly 100, the liquid inside the inner drum assembly 100 will be discharged through the drain hole 120 into the drain area between the inner drum assembly 100 and the outer drum assembly 210, and then discharged.

[0051] Understandably, in order to further reduce the probability of residual liquid flowing back into the inner cylinder body 110 between the outer cylinder assembly 210 and the inner cylinder assembly 100, the number of drainage holes 120 can be minimized while ensuring drainage efficiency. In some embodiments, the inner cylinder assembly 100 can be cylindrical, and the drainage holes 120 can be arranged in a single row or multiple rows along the outer periphery of the cylinder, minimizing the number of rows of drainage holes 120 while ensuring drainage efficiency.

[0052] As shown in Figure 4, in one embodiment, the length of the drainage zone along the length direction of the cylinder wall 111 is 1cm to 20cm.

[0053] In this technical solution, specific parameters of the drainage zone are further provided. The length of the drainage zone can be from 1cm to 20cm. That is, drainage holes 120 are arranged within 1cm to 20cm along the length of the cylinder wall 111. The other areas of the cylinder wall 111 are the isolation zone. Drainage holes 120 do not need to be arranged in other areas, so that most of the inner cylinder body 110 is an isolation zone. When the inner cylinder assembly 100 is applied to the clothing processing equipment, most of the area between the inner cylinder assembly 100 and the outer cylinder assembly 210 is a 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 clothing processing more hygienic and water-saving.

[0054] As shown in Figure 4, in one embodiment, the drainage zone and the isolation zone are arranged adjacent to each other, and the ratio of the length of the drainage zone to the length of the isolation zone along the length direction of the cylinder wall 111 is 0.1 to 0.4.

[0055] In this technical solution, the relationship between the drainage zone and the isolation zone is further provided. The ratio of the length of the drainage zone to the length of the isolation zone along the length of the cylinder wall 111 is 0.1 to 0.4. That is to say, most of the area of ​​the inner cylinder body 110 is the isolation zone, and a smaller part of the area is the drainage zone. When the inner cylinder assembly 100 is applied to the clothing processing equipment, most of the area between the inner cylinder assembly 100 and the outer cylinder assembly 210 is a 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 clothing processing more hygienic and water-saving.

[0056] As shown in Figures 1 and 2, in one embodiment, the inner cylinder assembly 100 further includes a separator 130, which is connected to the inner cylinder body 110, arranged at the junction of the drainage area and the isolation area, and at least covers a portion of the drainage area.

[0057] In this technical solution, the structural composition of the inner cylinder assembly 100 is further provided. The inner cylinder assembly 100 may include a separator 130, which is connected to the inner cylinder body 110 and arranged at the connection between the drainage area and the isolation area. That is, the separator 130 can divide the cylinder wall 111 of the inner cylinder body 110 to form a drainage area and an isolation area. Based on this, during the use of the inner cylinder assembly 100, the separator 130 can make close contact with the outer cylinder assembly 210 of the garment processing equipment or the components on the outer cylinder assembly 210. During the rotation of the inner cylinder assembly 100, the partition 130 serves to support and seal the space. This arrangement serves two purposes: firstly, it facilitates the formation of a liquid-free space 280 and a drainage space 290 between the inner cylinder assembly 100 and the outer cylinder assembly 210, thereby reducing the amount of liquid residue; secondly, it places the main friction points of the inner cylinder assembly 100 on the partition 130, reducing the wear of the inner cylinder body 110, lowering the probability of deformation of the inner cylinder assembly 100, and ensuring the service life of the inner cylinder assembly 100.

[0058] In this technical solution, considering that the partition 130 needs to have a certain width to achieve a better sealing effect, and that the drainage area, due to the drainage hole 120, has a slightly lower mechanical strength than the isolation area, the partition 130 can cover part of the drainage area, thereby improving the sealing effect and further reducing the probability of deformation of the inner cylinder body 110. Furthermore, typically, to facilitate the fabrication 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 with the partition 130 also facilitates the assembly of the partition 130.

[0059] As shown in Figures 1 and 2, in one embodiment, the separator 130 includes: a first sealing member 131, which is sleeved on the inner cylinder body 110; and a clearance opening 132, which is formed on the first sealing member 131 to avoid the drain hole 120.

[0060] In this technical solution, the structural composition of the separator 130 is further provided. The separator 130 may include a first sealing member 131 and a relief opening 132. The first sealing member 131 is sleeved on the inner cylinder body 110 and abuts against the outer cylinder assembly 210 or a component on the outer cylinder assembly 210. This can form a liquid-free space 280 and a liquid drainage space 290 between the inner cylinder assembly 100 and the outer cylinder assembly 210, while facilitating the rotation of the inner cylinder assembly 100 relative to the outer cylinder assembly 210.

[0061] In this technical solution, by opening a clearance opening 132 on the first sealing member 131, the clearance opening 132 can make way for the drain hole 120, so that the liquid in the inner drum body 110 can be discharged through the drain hole 120, which is especially convenient for the clothes in the inner drum assembly 100 to be spun dry.

[0062] As shown in Figures 1 and 2, in one embodiment, an installation part is also formed on the drainage area, and the first sealing member 131 is connected to the inner cylinder body 110 through the installation part.

[0063] In this technical solution, in order to facilitate the assembly of the first sealing element 131, an installation part can also be formed on the drainage area. The first sealing element 131 is connected to the inner cylinder body 110 through the installation part, which can improve the fixing strength of the first sealing element 131 and facilitate the assembly of the first sealing element 131.

[0064] In some examples, the mounting section may include a screw hole formed above the drainage area.

[0065] In some examples, in order to ensure the sealing effect of the first seal 131, a sealing layer 1311 may be formed on the side of the first seal 131 facing the inner cylinder body 110, and the sealing layer 1311 may be made of rubber material.

[0066] As shown in Figure 3, in one embodiment, the inner cylinder body 110 further includes: a cylinder bottom 112, a cylinder wall 111 connected to the cylinder bottom 112, and a drain hole 120 disposed near the cylinder bottom 112.

[0067] In this technical solution, the inner tube body 110 may also include a tube bottom 112, which is connected to the tube wall 111. The tube bottom 112 and the tube wall 111 can enclose and form a receiving space, which can be used to store clothing.

[0068] In this technical solution, the drain hole 120 is located near the bottom 112 of the cylinder. This arrangement has several advantages: First, the end of the inner cylinder body 110 closest to the bottom 112 has higher mechanical strength. The drain hole 120, located at the end of the cylinder wall 111 closest to the bottom 112, ensures the mechanical strength of the inner cylinder body 110 and facilitates the opening of the drain hole 120. Second, when the clothes inside the inner cylinder assembly 100 are being dehydrated, the rotation of the inner cylinder assembly 100 facilitates the collection of liquid towards the drain hole 120, improving drainage efficiency. Third, the drain area formed at the end of the cylinder wall 111 closest to the bottom 112 allows the drain space 290 formed between the inner cylinder assembly 100 and the outer cylinder assembly 210 to be located near the end of the inner cylinder assembly 100 or the clothes processing device, facilitating the drainage of liquid through the clothes processing device.

[0069] As shown in Figure 3, in one embodiment, the inner cylinder assembly 100 further includes an exhaust port 140, which is formed on the bottom of the cylinder 112; wherein the exhaust port 140 is formed in the middle region of the bottom of the cylinder 112.

[0070] In this technical solution, considering some usage scenarios and needs, it may involve drying clothes through clothing processing equipment, and the setting of exhaust port 140 facilitates the discharge of water vapor.

[0071] It is understandable that the vent 140 is located in the middle area of ​​the bottom 112 of the tub. In other words, the height of the vent 140 can be higher than the preset height of the liquid level inside the inner tub body 110. Based on this, when clothes are processed through the inner tub assembly 100, the liquid will not overflow through the vent 140, thus improving the user experience.

[0072] In one embodiment, the inner cylinder body 110 is cylindrical. This design facilitates the manufacturing and processing of the inner cylinder body 110 and reduces costs.

[0073] In one embodiment, the inner drum body 110 is frustoconical in shape, and the drain hole 120 is located at the flared end of the frustoconical inner drum body 110. This design, by making the inner drum body 110 frustoconical, allows more liquid to collect in the drain area of ​​the inner drum body 110 during the dehydration of clothes inside, facilitating quick and thorough dehydration of the clothes.

[0074] As shown in Figure 2, in one 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.

[0075] 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.

[0076] As shown in Figure 1, in one embodiment, the inner cylinder assembly 100 further includes a second seal 160, which is disposed between the retainer 150 and the cylinder wall 111.

[0077] 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. This arrangement can reduce or eliminate the probability of liquid overflowing through the gap between the inner cylinder assembly 100 and the retainer 150.

[0078] As shown in Figure 1, in one embodiment, the inner tube assembly 100 further includes a lifting rib 170, which is arranged on the inner wall of the inner tube body 110. The lifting rib 170 improves the cleaning effect of garment processing.

[0079] As shown in Figure 1, in one embodiment, the inner cylinder assembly 100 further includes: a first fastener 180; a recessed groove 113 is formed at the open end of the inner cylinder body 110, so that a first wall surface 114 and a second wall surface 115 are formed at the open end of the inner cylinder body 110 along the direction from the outer wall to the inner wall of the inner cylinder assembly 100; wherein, a retainer 150 is recessed in the recessed groove 113, the first fastener 180 passes through the first wall surface 114 and is connected to the retainer 150, and a second seal 160 is arranged between the second wall surface 115 and the retainer 150; wherein, a finished surface 151 is formed on the side of the retainer 150 facing the bottom of the recessed groove 113.

[0080] 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.

[0081] In this technical solution, the inner cylinder assembly 100 may also include a first fastener 180, which passes through the first wall surface 114 and is connected to the retainer 150, thereby making the fixation of the retainer 150 more reliable.

[0082] In this technical solution, the second seal 160 is arranged between the second wall surface 115 and the retainer 150, which can ensure the sealing relationship between the second wall surface 115 and the retainer 150 and reduce the probability of liquid leakage.

[0083] In this technical solution, the retainer 150 has a finished surface 151 on the side facing the bottom of the sink 113. This arrangement can reduce the wear of the retainer 150 and the inner cylinder body 110.

[0084] As shown in Figures 1 to 13, a garment processing device is provided according to a second aspect of the embodiments of this application, including: an inner tube assembly 100 as described in any of the above technical solutions.

[0085] The garment processing device provided in this application includes the inner tube assembly 100 of any of the above-described technical solutions. Therefore, the garment processing device has all the beneficial effects of the inner tube assembly 100 of the above-described technical solutions, which will not be elaborated here.

[0086] As shown in Figures 5 to 8, in Figure 8, the area formed by the large squares is the drainage space 290, and the area formed by the small squares is the liquid-free space 280. In one embodiment, the garment processing device further includes: an outer cylinder assembly 210, with an inner cylinder assembly 100 arranged inside the outer cylinder assembly 210; and an isolation component 220 connected to the outer cylinder assembly 210. The isolation component 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. The isolation component 220, the inner wall of the outer cylinder assembly 210, and the drainage area of ​​the inner cylinder assembly 100 enclose the drainage space 290.

[0087] In this technical solution, the structure of the garment processing equipment is further provided. The garment processing equipment includes an outer drum assembly 210 and an insulating assembly 220. Based on this, the inner drum assembly 100 is disposed inside the outer drum assembly 210. The insulating assembly 220 is connected to the outer drum assembly 210 and also serves to support the inner drum assembly 100. When the garment is processed by the garment processing equipment, the garment is placed in the receiving space inside the inner drum body 110. Then, water and detergent are injected into the inner drum body 110. With the movement of the inner drum body 110, the garment can be cleaned.

[0088] In this technical solution, when the inner drum assembly 100 is assembled into the outer drum assembly 210, the insulating component 220 contacts and seals with the inner drum body 110. Based on this, two spaces can be formed between the insulating component 220, the inner drum assembly 100, and the outer drum assembly 210. The space enclosed by the drain area of ​​the drum wall 111 is the drain space 290, and the space enclosed by the isolation area of ​​the drum wall 111 is the liquid-free space 280. The drain hole 120 opened in the drain area leads to the drain space 290. When washing clothes through the clothes processing equipment, due to the formation of the liquid-free space 280, only a small amount of water is needed to fill the drain space 290 to wash the clothes, which makes the clothes processing equipment more water-saving. When the garment processing equipment is dehydrating, the inner drum body 110 can be rotated by controlling the inner drum body 110. Under the action of centrifugal force, the liquid inside the inner drum body 110 can enter the drain space 290 through the drain hole 120 and then be discharged outside the garment processing equipment. Similarly, due to the formation of the liquid-free space 280, the amount of liquid residue will be reduced, making the garment processing equipment more hygienic when washing clothes.

[0089] As shown in Figures 5 and 9, in one embodiment, the isolation component 220 includes a third seal 221, which is connected to the outer cylinder component 210 and is used to abut and seal with the separator 130 of the inner cylinder component 100.

[0090] In this technical solution, the structure of the isolation component 220 is further provided. The isolation component 220 may include a third seal 221. By abutting and sealing the third seal 221 with the separator 130, the space enclosed between the inner drum assembly 100 and the outer drum assembly 210 can be divided into a liquid-free space 280 and a drain space 290. The liquid only needs to fill the drain space 290 for washing, which saves more water. At the same time, when the garment processing equipment is dehydrating, it can make the garment processing equipment drain more thoroughly and reduce the amount of liquid residue.

[0091] As shown in Figure 11, in some examples, a limiting member 2121 can also be formed on the second cylinder 212, and the third seal 221 is connected to the limiting member 2121. The limiting member 2121 can suppress the movement of the third seal 221, making the fixation of the third seal 221 more reliable.

[0092] As shown in Figures 5, 9 and 11, in one embodiment, the insulating assembly 220 includes a door seal assembly 222, which is connected to the outer cylinder assembly 210 and is used to abut and seal against the retainer 150 of the inner cylinder assembly 100.

[0093] In this technical solution, the structure of the isolation component 220 is further provided. The isolation component 220 may also include a door seal component 222. The door seal component 222 is mainly used to seal the open end of the inner cylinder body 110. By abutting and sealing the retainer 150 through the door seal component 222, liquid will not enter the gap between the inner cylinder assembly 100 and the outer cylinder assembly 210 through the open end of the inner cylinder assembly 100, which can further reduce the amount of liquid residue between the inner cylinder assembly 100 and the outer cylinder assembly 210.

[0094] As shown in Figures 5, 9 and 12, in one embodiment, the door seal assembly 222 includes: a door seal body 2221, which is connected to the end of the outer cylinder assembly 210; an injection port, which is opened on the door seal body 2221 and leads to the receiving space inside the inner cylinder assembly 100; and a reinforcing ring 2223, which is disposed inside the door seal body 2221 and sleeved on the inner cylinder assembly 100.

[0095] In this technical solution, the structural composition of the door seal assembly 222 is further provided. The door seal assembly 222 may include a door seal body 2221, a liquid injection port and a reinforcing ring 2223. The door seal body 2221 is also connected to the outer drum assembly 210. The liquid injection port facilitates the injection of water and detergent for washing clothes into the inner drum assembly 100, making the use of the clothes processing equipment more convenient.

[0096] In some examples, a drying duct vent 2222 may also be formed on the door seal assembly 222, which leads to the inner cylinder body. The liquid injection port is formed in the upper area of ​​the door seal assembly 222, avoiding the drying duct vent 2222. This arrangement facilitates sealing of the liquid injection port. The specific style of the liquid injection port may include a water inlet or a nozzle.

[0097] In this technical solution, since the door seal assembly 222 is located on one side of the open end of the inner cylinder assembly 100, the mechanical strength of the inner cylinder assembly 100 is relatively weak at this position. Therefore, a reinforcing ring 2223 can be set inside the door seal assembly 222. When the door seal assembly 222 is fitted onto the inner cylinder assembly 100, the probability of deformation of the door seal assembly 222 can be reduced, thereby including the inner cylinder assembly 100, and especially reducing the probability of deformation of the inner cylinder body 110.

[0098] As shown in Figure 5, in one 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.

[0099] In this technical solution, the garment processing equipment may also include a housing 230 and a first drain pipe 240. The outer cylinder assembly 210 is disposed inside the housing 230 and is connected to the drain space 290 through the 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.

[0100] 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.

[0101] As shown in Figures 5, 9 and 12, 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.

[0102] In one embodiment, 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 sleeved on the first cylinder 211 through the mounting surface 2111.

[0103] In this technical solution, the structure of the outer cylinder assembly 210 is further provided. The outer cylinder assembly 210 may include a first cylinder 211 and a second cylinder 212. This arrangement facilitates the placement of the inner cylinder assembly 100 inside the outer cylinder assembly 210. For example, during the assembly process, the inner cylinder assembly 100 can be placed inside one of the first cylinder 211 or the second cylinder 212, and then the first cylinder 211 and the second cylinder 212 can be connected to encapsulate the inner cylinder assembly 100 inside the outer cylinder assembly 210, which facilitates the assembly of the garment processing equipment.

[0104] In this technical solution, an assembly surface 2111 is formed on the outer surface of the first cylinder 211. The door seal body 2221 of the isolation component 220 is fitted onto the first cylinder 211 through the assembly surface 2111. This arrangement makes the connection between the isolation component 220 and the first cylinder 211 more reliable and reduces the probability of the isolation component 220 becoming loose.

[0105] In some examples, the mounting surface 2111 may include a rough surface formed on the first cylinder 211 or a groove formed on the first cylinder 211, or other structures that can increase the fixing strength of the insulating component 220.

[0106] As shown in Figure 5, in one embodiment, the garment processing device further includes: a door 250 connected to the outer tube assembly 210; and a drive assembly 260, with a drive component 261 connected to the inner tube assembly 100 for driving the inner tube assembly 100 to rotate.

[0107] In this technical solution, the garment processing equipment may also include a door 250, which facilitates sealing of the garment processing equipment.

[0108] In this technical solution, the garment processing equipment may also include a drive component 260, which is connected to the inner drum assembly 100 to facilitate the rotation of the inner drum assembly 100. By controlling the rotation speed of the inner drum assembly 100, the garment processing equipment can be controlled to clean or dehydrate the garments.

[0109] As shown in Figures 5 and 6, in one embodiment, the drive assembly 260 includes: a drive member 261; a flange 262, the output end of the drive member 261 is connected to the flange 262, and the flange 262 is connected to the inner cylinder assembly 100; wherein, a second fastener 270 passes through the cylinder wall 111 and the separator 130 of the inner cylinder assembly 100 and is connected to the flange 262.

[0110] In this technical solution, the structural composition of the drive assembly 260 is further provided. The drive assembly 260 may include a drive element 261 and a flange 262. The flange 262 is connected to the inner cylinder assembly 100. When the drive element 261 is turned on, the drive element 261 drives the flange 262 to rotate, and the flange 262 can drive the inner cylinder assembly 100 to rotate.

[0111] In this technical solution, a connection method for the flange 262 is further provided. The second fastener 270 passes through the cylinder wall 111 and the separator 130 and is then connected to the flange 262, so that the flange 262 and the separator have a connection relationship. This allows the flange 262, the inner cylinder body 110 and the separator to rotate synchronously, which can reduce the probability of the separator being misaligned and ensure the reliability of the garment processing equipment.

[0112] As shown in Figure 13, in one embodiment, the garment processing device further includes: a rotating shaft 2110, which is arranged above the inner drum body 110; and a sealing strip 2120, which is sleeved on the rotating shaft 2110 and the inner drum body 110, and is used to cover the drain hole 120 located below the inner drum body 110.

[0113] In this technical solution, a design for the isolation component 220 is further provided. The isolation component 220 may include a rotating shaft 2110 and a sealing strip 2120. The sealing strip 2120 is fitted onto the inner cylinder body 110. When the inner cylinder body 110 rotates, the sealing strip 2120 rotates synchronously with the inner cylinder body 110. Through the setting of the sealing strip 2120, the sealing strip 2120 can always cover the drain hole 120 at the bottom of the inner cylinder body 110. Based on this, even if some liquid remains between the inner cylinder body 110 and the outer cylinder assembly 210, this liquid cannot enter the inner cylinder body 110 through the drain hole 120, making the clothing processing equipment more hygienic in processing clothing. Meanwhile, when washing clothes through the garment processing equipment, liquid is injected into the inner drum assembly 100. Since the drain 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. It is only necessary to meet the liquid level requirements of the inner drum body 110 to carry out washing, which saves more water.

[0114] It is understandable that when the insulating component 220 includes the sealing strip 2120 and the rotating shaft 2110, when it is necessary to dehydrate the clothes, the inner drum body 110 can also be rotated by the driving component. Under the action of centrifugal force, the liquid in the inner drum body 110 can be discharged outside the inner drum assembly 100 through the drain hole 120 at the top of the inner drum body 110.

[0115] The clothing processing device provided in this application embodiment, when the drive component 261 is turned on, the drive component 261 drives the flange 262 to rotate, and the flange 262 drives the inner drum body 110, the separator 130, the retainer 150 and the second seal 160 to rotate. The clothing is placed inside the inner drum body 110, and cleaning water and detergent are injected into the inner drum assembly 100 through the door seal assembly 222. The clothing is cleaned by rotating the inner drum body 110. The inner cylinder assembly 100 and the outer cylinder assembly 210 form a first sealing structure through the separator 130 and the third sealing element 221, and a second sealing structure through the door seal assembly 222 and the second sealing element 160. Based on this, the drainage areas of the outer cylinder assembly 210 and the inner cylinder assembly 100 can enclose a drainage space 290, while a liquid-free space 280 can be enclosed between the isolation areas of the outer cylinder assembly 210 and the inner cylinder assembly 100. Due to the formation of the drainage area and the isolation area, only a portion of the liquid accumulates in the drainage space 290 through the drainage hole 120. Since no drainage hole 120 is provided in the isolation area, liquid from the inner cylinder assembly 100 will not enter. By draining the water into the liquid-free space, firstly, simply emptying the water in the drain space 290 prevents wastewater from flowing back into the inner drum body 110, reducing the probability of dirt from the outer drum assembly contaminating the clothes being washed, reducing or eliminating cross-contamination, and ensuring the hygienic condition of the clothes being processed; secondly, during the washing process, the washing liquid does not enter the liquid-free space 280, so the liquid-free space 280 also needs to be filled with washing liquid. Only the washing liquid needs to fill the drain space 290, and the clothes can be processed through the inner drum body 110, which can reduce the amount of water and detergent used, making it more energy-efficient and environmentally friendly.

[0116] In the specific dehydration process, the clothing processing equipment provided in this application embodiment can drive the inner drum body 110 to rotate through the drive component 261. Under the action of centrifugal force, the liquid in the inner drum body 110 is discharged into the drain space 290 through the drain port, and then discharged outside the clothing processing equipment through the first drain pipe 240. At the same time, the liquid located at the opening end of the inner drum assembly 100, near the door seal assembly 222, can be discharged into the first drain pipe 240 through the drain channel 2224 and the second drain pipe 2225. Based on this, the clothing can be dehydrated.

[0117] Compared with the prior art, this application has at least the following beneficial effects:

[0118] The inner cylinder assembly provided in this application embodiment includes an inner cylinder body and multiple drainage holes. The inner cylinder body includes a cylinder wall, which forms a drainage area and an isolation area along its length. The drainage holes are only arranged in the drainage area; that is, no drainage holes are arranged in the isolation area. Therefore, during use of the inner cylinder assembly, the inner wall encloses a receiving space to hold the clothing to be processed. The inner cylinder body and the outer cylinder assembly of the clothing processing device can have a sealed relationship. Since the drainage areas of the outer cylinder assembly and the inner cylinder assembly can enclose a drainage space, and the isolation area between the outer cylinder assembly and the inner cylinder assembly can enclose a liquid-free space, when processing clothing with the inner cylinder assembly, due to the formation of the drainage area and the isolation area, only a portion of the liquid accumulates in the drainage space through the drainage holes. Since no drainage holes are provided in the isolation area, the liquid inside the inner cylinder assembly... Since the liquid will not enter the liquid-free space, firstly, by simply draining the water from the drain space, wastewater can be prevented from flowing back into the inner drum body, reducing the probability of dirt from the outer drum components contaminating the clothes during washing, reducing or eliminating cross-contamination, and ensuring the hygienic condition of the clothes. Secondly, during the washing process, the washing liquid will not enter the liquid-free space, so it is also necessary to fill the liquid-free space with washing liquid. Only the washing liquid needs to fill the drain space, and the clothes can be treated through the inner drum body, which can reduce the amount of water and detergent used, making it more energy-efficient and environmentally friendly.
