[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Please refer to Figure 1 to Figure 6 An embodiment of the present application provides a clothing processing device, which includes a housing and a drum assembly according to any one embodiment of the present application.

[0041] It should be noted that the clothing processing device may be a washing machine, or a washing-drying machine, etc., which is not limited here. Specifically, in the embodiment of the present application, a drum washing machine is used as an example.

[0042] The box body can be understood as the external supporting structure of the clothes processing device, and its specific shape is not limited. For example, the box body is roughly a cubic structure, and the box body is placed on the ground, and its stability is relatively better.

[0043] The cylinder assembly is disposed inside the cabinet. That is to say, the cabinet can provide an installation base for the cylinder assembly.

[0044] Please also refer to Figures 1 to 6 , an embodiment of the present application further provides a cylinder assembly. The cylinder assembly is used for a laundry treatment device and includes a drum 10, a door body 20, and a door seal 30.

[0045] The drum 10 is configured to perform functions such as washing, dehydrating, or drying clothes. The drum 10 has a laundry treatment chamber 10a and a laundry loading opening 10b communicating with the laundry treatment chamber 10a. The clothes are washed and cared for in the laundry treatment chamber 10a, and the user can take in and out the clothes through the laundry loading opening 10b.

[0046] It should be noted that the drum 10 in the embodiment of the present application is a perforation-free drum, that is, the drum 10 can hold water. When the laundry treatment device is washing clothes, the washing liquid is contained in the drum 10. Due to this structure of the drum 10, since it can hold the washing liquid by itself, an outer cylinder does not need to be sleeved outside the drum 10. During the process of washing clothes, after closing the laundry loading opening 10b, the washing liquid can be effectively prevented from leaking out.

[0047] The door body 20 has an open state and a closed state.

[0048] In the open state, the laundry loading opening 10b communicates with the outside. Thus, the user can take in and out the clothes through the laundry loading opening 10b.

[0049] In the closed state, the door body 20 cuts off the communication path between the laundry loading opening 10b and the outside. Thus, the washing liquid in the laundry treatment chamber 10a can be effectively prevented from leaking out.

[0050] The door body 20 includes a frame 21 and a protruding structure 22. The frame 21 is disposed on the drum 10. The frame 21 includes an inner frame 211 and an outer frame 212. A part of the protruding structure 22 is clamped between the inner frame 211 and the outer frame 212. Thus, the protruding structure 22 has higher stability and reliability in mounting on the frame 21.

[0051] The inner frame 211 and the outer frame 212 can be an integrally formed structure; of course, the two can also be a split structure, and the split inner frame 211 and outer frame 212 are formed into the frame 21 through assembly.

[0052] The protruding structure 22 protrudes from a side of the frame 21 close to the laundry loading opening 10b. When the door body 20 is in the closed state, the protruding structure 22 can extend into the laundry loading opening 10b. Thus, it is beneficial to improve the sealing effect of the door body 20.

[0053] There is no limitation on the connection method between the frame 21 and the drum 10. Exemplarily, the cylinder assembly further includes a door hinge, and the frame 21 is mounted on the drum 10 through the door hinge. Thus, it is convenient for the door body 20 to switch between the open state and the closed state.

[0054] It can be understood that since the frame 21 is provided on the drum 10, the door body 20 can rotate or stop following the drum 10.

[0055] There is no limitation on the specific type of the protruding structure 22. Exemplarily, the protruding structure 22 is a glass product.

[0056] The protruding structure 22 protrudes from the side of the frame 21 close to the clothing inlet 10b. That is to say, the protruding structure 22 extends beyond the surface of the frame 21 on the side close to the clothing inlet 10b.

[0057] There is no limitation on the specific structure of the frame 21. Exemplarily, as Figure 1 and Figure 2 shown, the frame 21 is annular. For example, it is a circular ring. That is, the frame 21 is provided with an opening penetrating through both axial sides thereof, and the protruding structure 22 is arranged at the opening. Thus, when the protruding structure 22 is a glass product, the user's line of sight can pass through the protruding structure 22 and see the inside of the clothing treatment cavity 10a.

[0058] The door seal 30 is arranged on the door body 20. That is to say, the door body 20 provides an installation basis for the door seal 30, and during the process of the door body 20 switching between the open state and the closed state, the door seal 30 moves following the door body 20. It can be understood that after the door body 20 switches to the open state, the door seal 30 is separated from the clothing inlet 10b.

[0059] In the closed state, the door body 20 covers the drum 10, the protruding structure 22 extends into the clothing inlet 10b, and at least part of the door seal 30 is hermetically clamped between the side wall of the protruding structure 22 and the side wall of the clothing inlet 10b. That is to say, most of the area of the clothing inlet 10b is blocked by the protruding structure 22, and the gap between the side wall of the protruding structure 22 and the side wall of the clothing inlet 10b is sealed by the door seal 30.

[0060] When the door body 20 is in the closed state, the protruding structure 22 extends into the clothing inlet 10b. Thus, the sealing effect of the clothing inlet 10b can be improved.

[0061] Since both the protruding structure 22 and the drum 10 are made of hard materials, in order to prevent interference between the protruding structure 22 and the side wall of the clothing inlet 10b when the door body 20 switches between the open state and the closed state, the size of the protruding structure 22 needs to be designed to be smaller than that of the clothing inlet 10b. Therefore, when the door body 20 is in the closed state, there must be a gap between the protruding structure 22 and the clothing inlet 10b, and this gap is sealed by the door seal 30. Thus, it is beneficial to further improve the sealing effect of the clothing inlet 10b.

[0062] The door seal 30 can be made of various flexible materials, such as rubber, silicone, etc. When the door body 20 is in the closed state, the door seal 30 undergoes a certain elastic deformation and achieves an interference fit with the side wall of the clothing inlet 10b and the side wall of the protruding structure 22 respectively, which is beneficial to improving the sealing effect of the clothing inlet 10b.

[0063] In the related art, a clothing treatment device includes a drum and a door body. To prevent washing liquid from leaking out during the operation of the drum washing machine, a door seal is required to seal between the drum and the door body. Generally, a part of the door body is made of glass and another part is made of a frame. When the door seal is also installed on the door body, it is equivalent to completing the assembly of the glass, the frame, and the door seal, resulting in a relatively complex assembly structure and poor stability.

[0064] For the cylinder assembly of the embodiment of the present application, the frame 21 includes an inner frame 211 and an outer frame 212, and a part of the protruding structure 22 is clamped between the inner frame 211 and the outer frame 212. Thus, the assembly structure of the frame 21, the protruding structure 22, and the door seal 30 is relatively simple; at the same time, when a part of the door body 20 needs to use a glass product, the protruding structure 22 can be used as the glass product, and the protruding structure 22 is clamped by the inner frame 211 and the outer frame 212, making the installation of the protruding structure 22 on the frame 21 more stable.

[0065] In the related art, the cylinder assembly of a clothing treatment device includes a drum and an outer cylinder. The drum is a perforated drum, and the outer cylinder is sleeved outside the drum. The washing liquid is contained in the outer cylinder. Based on this structure of the cylinder assembly, since the outer cylinder contains the washing liquid, in order to prevent the washing liquid from leaking out during the operation of the clothing treatment device and at the same time ensure that the clothes in the drum are not thrown out, the door body needs to seal both the opening of the outer cylinder and the clothing inlet of the drum. In order to enable the door body to achieve the effect of sealing both the opening of the outer cylinder and the clothing inlet of the drum, generally, the door body is connected to the cabinet, the door seal is installed at the opening of the outer cylinder, and the design of the door seal also needs to prevent the washing liquid from flowing out through the clothing inlet. Therefore, the structure of the door seal is relatively complex. For example, it needs to be designed as a corrugated special-shaped structure, resulting in the problem that dirt and grime are easily hidden between the folds of the door seal.

[0066] In the cylinder assembly of the embodiment of the present application, the drum 10 is designed as a non-porous drum, and the washing liquid is directly contained in the laundry treatment chamber 10a. In this structure, the door seal 30 only needs to seal the gap between the drum 10 and the door body 20 (for example, the gap between the protruding structure 22 and the laundry inlet 10b) to effectively improve the problem of the leakage of the washing liquid. The design of the special-shaped structure of the traditional door seal in a corrugated shape can be simplified, which is beneficial to improving the problem of dirt accumulation in the door seal 30. Moreover, since the door seal 30 can seal the gap between the protruding structure 22 and the laundry inlet 10b, it is beneficial to reduce the probability of the washing liquid penetrating between the door seal 30 and the protruding structure 22 or between the door seal 30 and the laundry inlet 10b. That is, it is beneficial to reduce the contact area between the washing liquid and the door seal 30, and the door seal 30 does not necessarily need to be designed as a special-shaped structure in a corrugated shape, which is beneficial to improving the problem of dirt accumulation in the door seal 30.

[0067] Further, in the laundry treatment equipment in the related art, the door body is installed on the box body, and relative rotation will occur between the drum and the door body. The door seal is installed on the drum, and the door seal is in interference fit with the door body when the door body is in the closed state. When the drum rotates, there is a large frictional force between the door seal and the door body, which will affect the rotation of the drum; and when the door seal is installed on the door body and the door seal is in interference fit with the side wall of the laundry inlet when the door body is in the closed state, when the drum rotates, there is also a large frictional force between the door seal and the side wall of the laundry inlet, which will also affect the rotation of the drum. That is to say, on the premise that the cylinder assembly needs to facilitate the rotation of the drum, it is impossible to take into account the better sealing effect of the laundry inlet.

[0068] In the cylinder assembly of the embodiment of the present application, the door body 20 can be arranged on the drum 10 and rotate or stop rotating following the drum 10. During the operation of the laundry treatment equipment, there is no need for relative rotation between the door body 20 and the drum 10, and the gap between the protruding structure 22 and the side wall of the laundry inlet 10b can be hermetically sealed by the door seal 30. When the door body 20 is in the closed state, the sealing performance of the laundry inlet 10b is better. That is, the interference sealing fit of the door seal 30 will not affect the rotation of the drum 10. Therefore, the cylinder assembly of the embodiment of the present application can also take into account the better sealing effect of the laundry inlet 10b on the premise of facilitating the rotation of the drum 10.

[0069] Please refer to Figures 3 to 6 , in one embodiment, the door seal 30 includes a first connecting section 31 and a sealing portion 34. The first connecting section 31 is sleeved on the protruding structure 22. The sealing portion 34 has a connecting end 34a and a free end 34b. The connecting end 34a is connected to the first connecting section 31, and the free end 34b extends radially outward along the door body 20. When in the closed state, the side wall of the laundry inlet 10b is in sealing cooperation with the free end 34b.

[0070] The first connecting section 31 and the sealing portion 34 may be of an integral structure.

[0071] The door seal 30 is relatively stably mounted on the protruding structure 22 through the first connecting section 31. The first connecting section 31 extends along the circumferential direction of the clothing inlet 10b and presents a ring shape, such as a circular ring shape.

[0072] The sealing portion 34 is located outside the first connecting section 31 along the radial direction of the clothing inlet 10b and also extends along the circumferential direction of the clothing inlet 10b. The sealing portion 34 also presents a ring shape, such as a circular ring shape. The sealing portion 34 is used to seal the gap between the protruding structure 22 and the clothing inlet 10b. It can be understood that in the axial section of the cylindrical body assembly, the cross-section of the sealing portion 34 is strip-shaped, and the connecting end 34a and the free end 34b are respectively the opposite ends of the strip-shaped cross-section. From the overall perspective of the sealing portion 34, the free end 34b is the outer ring end face of the sealing portion 34 along the radial direction of the clothing inlet 10b, and the connecting end 34a is the inner ring end face of the sealing end along the radial direction of the clothing inlet 10b.

[0073] In this embodiment, the free end 34b is sealed with the side wall of the clothing inlet 10b. Specifically, an interference sealing fit can be achieved between the free end 34b and the side wall of the clothing inlet 10b. On the one hand, the sealing of the clothing inlet 10b can be better achieved; on the other hand, the washing liquid will basically only contact the sealing portion 34, which is beneficial to improving the problem of dirt accumulation on the door seal 30.

[0074] The specific number of the sealing portions 34 is not limited. Exemplarily, please refer to Figure 4 and Figure 6 The number of the sealing portions 34 is two, that is, the sealing portion 34 includes a first sealing portion 35 and a second sealing portion 36. Here, it means that the two sealing portions 34 are respectively the first sealing portion 35 and the second sealing portion 36, rather than saying that the first sealing portion 35 or the second sealing portion 36 is a certain component of the sealing portion 34.

[0075] The free ends 34b of the first sealing portion 35 and the second sealing portion 36 are arranged at intervals along the axial direction of the door body 20. The relative positional relationship between the free ends 34b of the first sealing portion 35 and the second sealing portion 36 is not limited. Exemplarily, as Figure 4 and Figure 6As shown, the free end 34b of the first sealing portion 35 is closer to the clothing treatment chamber 10a than the free end 34b of the second sealing portion 36. A seal is formed between the free end 34b of the first sealing portion 35 and the side wall of the clothing inlet 10b, and another seal is formed between the free end 34b of the second sealing portion 36 and the side wall of the clothing inlet 10b. Thus, multiple seals are formed between the door seal 30 and the side wall of the clothing inlet 10b, which is conducive to further improving the sealing effect of the clothing inlet 10b.

[0076] In other embodiments, the number of the sealing portions 34 can be even more, such as three, four, six, etc. The specific number of the sealing portions 34 can be set according to the size of the clothing inlet 10b, the standard of the sealing effect, etc.

[0077] It should be noted that the connecting ends 34a of the first sealing portion 35 and the second sealing portion 36 can be shared, that is, the first sealing portion 35 and the second sealing portion 36 have the same connecting end 34a. Specifically, as Figure 4 and Figure 6 shown, in this embodiment, the first sealing portion 35 and the second sealing portion 36 are generally in a "Y" - shaped structure as a whole; of course, the first sealing portion 35 and the second sealing portion 36 can also have their own connecting ends 34a respectively, that is, the first sealing portion 35 and the second sealing portion 36 are respectively connected to the first connecting section 31.

[0078] Please refer to Figure 4 and Figure 6 . In one embodiment, during the process of the door body 20 switching from the open state to the closed state, the protruding structure 22 and the side wall of the clothing inlet 10b act together to squeeze the free end 34b, and the free end 34b deflects relative to the connecting end 34a under the action of the squeezing force.

[0079] Taking the sealing portion 34 including the first sealing portion 35 and the second sealing portion 36 as an example. As Figure 6 shown, C shows the position of the first sealing portion 35 when the door body 20 is in the open state, and C' shows the position of the first sealing portion 35 when the door body 20 is in the closed state; D shows the position of the second sealing portion 36 when the door body 20 is in the open state, and D' shows the position of the second sealing portion 36 when the door body 20 is in the closed state.

[0080] During the process of the door body 20 switching from the open state to the closed state, when the free end 34b of the second sealing portion 36 contacts the side wall of the clothing inlet 10b, the door body 20 continues to move in the direction of switching to the closed state, and the free end 34b of the second sealing portion 36 is always in contact with the side wall of the clothing inlet 10b. That is to say, in the closed state of the door body 20, the free end 34b of the second sealing portion 36 abuts against the side wall of the clothing inlet 10b.

[0081] When the door body 20 is switched from the open state to the closed state, during the process that the protruding structure 22 rotates until the free end 34b of the sealing part 34 contacts the side wall of the clothing delivery opening 10b, the door body 20 continues to move in the direction of being switched to the closed state, the gap between the protruding structure 22 and the side wall of the clothing delivery opening 10b gradually decreases, and the sealing part 34 is squeezed, so that the free end 34b of the sealing part 34 deflects (i.e., elastically deforms) relative to the connecting end 34a of the sealing part 34, thereby effectively reducing the closing resistance during the process of switching the door body 20 to the closed state. At the same time, after the door body 20 is switched to the closed state, a good sealing effect is formed between the free end 34b and the protruding structure 22.

[0082] Please refer to Figure 3 and Figure 4 , in an embodiment, the free end 34b of the first sealing part 35 is closer to the clothing treatment cavity 10a than the free end 34b of the second sealing part 36. Taking the direction that enters the clothing treatment cavity 10a through the clothing delivery opening 10b and is parallel to the axial direction of the clothing delivery opening 10b as the reference direction, the extension direction of the first sealing part 35 forms an angle less than 90° with the reference direction, and the extension direction of the second sealing part 36 forms an angle greater than 90° with the reference direction.

[0083] It should be noted that here, the reference direction, the extension direction of the first sealing part 35, and the extension direction of the second sealing part 36 are all vector directions.

[0084] When the door body 20 is switched from the open state to the closed state, during Figure 6From the perspective shown, the second sealing portion 36 first contacts the side wall of the laundry inlet 10b. During the process of the door body 20 advancing towards the laundry inlet 10b, the second sealing portion 36 generates a clockwise deflection, thereby driving the first sealing portion 35 to generate a clockwise deflection. After the first sealing portion 35 touches the side wall of the laundry inlet, it continues to deflect. The first sealing portion 35 generates an elastic force towards the side wall of the laundry inlet 10b, causing the first sealing portion 35 to abut against the side wall of the laundry inlet 10b. The first sealing portion 35 is driven by the second sealing portion 36 to deflect, so that both the first sealing portion 35 and the second sealing portion 36 are sealed with the side wall of the laundry inlet 10b, thereby effectively reducing the closing resistance during the process of switching the door body 20 to the closed state. At the same time, when the door body 20 is in the closed state, the included angle between the side of the first sealing portion 35 facing the laundry treatment chamber 10a and the side wall of the laundry inlet 10b is an obtuse angle. Even if the washing liquid impacts the first sealing portion 35 and applies a force to the first sealing portion 35, this force is opposite to the reference direction. Under the action of this force, the free end 34b of the first sealing portion 35 will squeeze the side wall of the laundry inlet 10b. That is to say, the included angle between the extending direction of the first sealing portion 35 and the reference direction is less than 90°. Even if the washing liquid impacts the first sealing portion 35, the sealing effect between the free end 34b of the first sealing portion 35 and the side wall of the laundry inlet 10b will even be better.

[0085] In addition, the included angle between the extending direction of the second sealing portion 36 and the reference direction is greater than 90°. When the door body 20 is in the closed state, a triangular structure is formed among the first sealing portion 35, the second sealing portion 36 and the side wall of the laundry inlet 10b, and the two included angles formed with the side wall of the laundry inlet 10b are acute angles, with better stability, which is conducive to improving the sealing effect of the door seal 30 on the laundry inlet 10b.

[0086] Please refer to Figure 4 and Figure 6 In one embodiment, the free end 34b of the first sealing portion 35 is closer to the laundry treatment chamber 10a than the free end 34b of the second sealing portion 36. The dimension of the end wall of the free end 34b of the second sealing portion 36 along the axial direction of the door body 20 is greater than the dimension of the end wall of the free end 34b of the first sealing portion 35 along the axial direction of the door body 20. Or rather, in the closed state, the contact area between the free end 34b of the second sealing portion 36 and the side wall of the laundry inlet 10b is greater than the contact area between the free end 34b of the first sealing portion 35 and the side wall of the laundry inlet 10b.

[0087] In this embodiment, at least double seals are adopted between the door seal 30 and the side wall of the clothing inlet 10b. A first sealing structure is formed between the free end 34b of the first sealing portion 35 and the side wall of the clothing inlet 10b. The contact area between the free end 34b of the first sealing portion 35 and the side wall of the clothing inlet 10b is small, so that it is convenient for the free end 34b of the first sealing portion 35 to deflect relative to the connecting end 34a, that is, the closing resistance during the process of switching the door body 20 to the closed state can be reduced; and a second sealing structure is formed between the free end 34b of the second sealing portion 36 and the side wall of the clothing inlet 10b. Even if the washing liquid passes through the free end 34b of the first sealing portion 35, due to the large contact area between the free end 34b of the second sealing portion 36 and the side wall of the clothing inlet 10b, the washing liquid can be better blocked. That is to say, in this embodiment, on the premise of reducing the closing resistance during the process of switching the door body 20 to the closed state, the sealing effect of the clothing inlet 10b can be better improved.

[0088] In one embodiment, please refer to Figures 4 to 6 , in the axial section of the cylinder assembly, the sealing surface formed by the free end 34b of the first sealing portion 35 and the side wall of the clothing inlet 10b is the first sealing surface, and the sealing surface formed by the free end 34b of the second sealing portion 36 and the side wall of the clothing inlet 10b is the second sealing surface. The first sealing surface and the second sealing surface are in the same plane.

[0089] That is to say, in the axial section of the cylinder assembly, the side wall of the clothing inlet 10b for sealing cooperation with the first sealing portion 35 and the side wall for sealing cooperation with the second sealing portion 36 are in the same plane.

[0090] During the process of the door body 20 switching from the open state to the closed state, the first sealing portion 35 and the second sealing portion 36 can simultaneously achieve sealing cooperation with the side wall of the clothing inlet 10b.

[0091] In addition, since the first sealing surface and the second sealing surface are in the same plane, during the process of the door body 20 switching to the closed state, both the first sealing portion 35 and the second sealing portion 36 approach the side wall of the clothing inlet 10b along the same direction, and the side wall of the clothing inlet 10b does not need to form a corner. That is, during the process of the door body 20 switching to the closed state, it is beneficial to reduce the probability of interference between the first sealing portion 35 or the second sealing portion 36 and the side wall of the clothing inlet 10b, so that it is convenient to switch the door body 20 to the closed state, and it is also beneficial to improve the sealing stability of the clothing inlet 10b.

[0092] The specific structure of the first connecting section 31 is not limited. Exemplarily, please refer to Figure 3 and Figure 4, the first connecting section 31 includes a connecting body 311 and a sealing body 312 connected to the connecting body 311. The connecting body 311 is sleeved on the side wall of the protruding structure 22, and the sealing body 312 is hermetically clamped between the connecting body 311 and the protruding structure 22.

[0093] The connecting body 311 and the sealing body 312 may be an integral structure. Both the connecting body 311 and the sealing body 312 are in a ring structure, and the sealing body 312 is located inside the connecting body 311 in the radial direction.

[0094] In this embodiment, an interference sealing fit is achieved between the sealing body 312 and the protruding structure 22, which is beneficial to enhancing the stability and reliability of the connection between the door seal 30 and the door body 20.

[0095] Please refer to Figure 4 and Figure 6 , in one embodiment, the number of the sealing bodies 312 is multiple, and the sealing bodies 312 are arranged at intervals along the axial direction of the door body 20.

[0096] It should be noted that the multiple in the embodiments of the present application refers to any number of two or more. Exemplarily, as Figure 6 shown, the number of the sealing bodies 312 is three.

[0097] Please refer to Figure 3 and Figure 4 , the protruding structure 22 includes a protruding portion 222 and a disc body 221 surrounding the protruding portion 222. The disc body 221 is arranged between the outer frame 212 and the inner frame 211. The protruding portion 222 protrudes from the disc body 221 along the axial direction of the door body 20. The inner frame 211 further includes a stop structure 2111. The stop structure 2111 is located on the side of the disc body 221 close to the clothing delivery port 10b along the axial direction of the door body 20. A part of the door seal 30 is sleeved on the protruding portion 222, and the other part is clamped between the stop structure 2111 and the disc body 221.

[0098] The protruding portion 222 and the disc body 221 may be an integral structure.

[0099] Please refer to Figure 4 and Figure 6 , when the door body 20 is in the closed state, the protruding portion 222 extends into the clothing delivery port 10b, and the disc body 221 is located outside the clothing delivery port 10b.

[0100] Both the disc body 221 and the stop structure 2111 are generally in a ring shape.

[0101] In this embodiment, through the cooperation of the disc body 221 and the stop structure 2111, it is beneficial to improve the stability and reliability of the installation of the protruding structure 22 on the frame 21. At the same time, the stability and reliability of the installation of the door seal 30 on the door body 20 are also improved.

[0102] Please refer to Figure 3 and Figure 4 In one embodiment, a part of the door seal 30 is clamped between the frame 21 and the protruding structure 22. Specifically, a part of the door seal 30 is clamped between the disc body 221 and the stop structure 2111. After the door seal 30 is installed on the door body 20, in the axial direction of the door body 20, the door seal 30 is restricted by the disc body 221 and the stop structure 2111. Therefore, it is beneficial to improve the installation stability and reliability of the door seal 30 on the door body 20.

[0103] There is also a part of the door seal 30 clamped between the protruding part 222 and the stop structure 2111. Therefore, it is also beneficial to improve the installation stability and reliability of the door seal 30 in the radial direction of the door body 20.

[0104] In addition, since the protruding part 222 is provided on the disc body 221 and partially protrudes from the disc body 221. That is, an included angle is formed at the connection between the disc body 221 and the protruding part 222, and the door seal 30 also needs to form an included angle. Specifically, the door seal 30 includes a first connection section 31 and a second connection section 32, the first connection section 31 and the second connection section 32 are arranged at an included angle, the first connection section 31 is sleeved on the protruding part 222, the second connection part is clamped between the disc body 221 and the stop structure 2111, the first connection section 31 is restricted by the protruding part 222 in the radial direction of the door body 20, one end of the first connection section 31 close to the second connection section 32 is clamped between the protruding part 222 and the stop structure 2111, and is restricted by the protruding part 222 and the stop structure 2111 in the radial direction, while the second connection section 32 is restricted by the disc body 221 and the stop structure 2111 in the axial direction of the door body 20. Therefore, the installation stability and reliability of the door seal 30 on the door body 20 are better.

[0105] Please refer to Figure 3 and Figure 4 In one embodiment, the door seal 30 includes a first connection section 31, a second connection section 32 and a third connection section 33. The first connection section 31 is sleeved on the protruding part 222, the second connection section 32 and the third connection section 33 are both arranged on the first connection section 31, and the two are arranged at intervals along the axial direction of the door body 20. The second connection section 32 is clamped between the stop structure 2111 and the disc body 221, and the stop structure 2111 is clamped between the second connection section 32 and the third connection section 33.

[0106] The first connection section 31, the second connection section 32 and the third connection section 33 can be an integral structure.

[0107] The first connection section 31, the second connection section 32 and the third connection section 33 can all be annular structures, and the second connection section 32 and the third connection section 33 are both located on the outer side of the first connection section 31 in the radial direction.

[0108] A circular groove is formed between the second connecting section 32 and the third connecting section 33, and the stop structure 2111 is clamped between the side walls of the circular groove.

[0109] In this embodiment, the door seal 30 and the door body 20 are clamped with each other, so as to further improve the reliability and stability of the installation of the door seal 30 on the door body 20, and reduce the probability that the door seal 30 falls off the door body 20 during the process of the door body 20 switching between the open state and the closed state. Therefore, it is beneficial to improve the user experience.

[0110] Please refer to Figure 4 and Figure 6 In one embodiment, in the closed state, the third connecting section 33 is in sealing contact with the end wall of the clothing delivery port 10b away from the end of the clothing treatment cavity 10a.

[0111] Even if the washing liquid passes through the sealing portion 34, the third connecting section 33 can still block the washing liquid, thereby preventing the washing liquid from leaking out through the clothing delivery port 10b. That is to say, in this embodiment, on the premise of improving the reliability of the installation of the door seal 30 on the door body 20, the third connecting section 33 can also improve the sealing effect of the clothing delivery port 10b.

[0112] Please refer to Figure 3 and Figure 4 In one of the stop structure 2111 and the door seal 30, a limit protrusion 2111a is provided, and a limit groove 30a is provided on the other. At least a part of the limit protrusion 2111a is arranged in the limit groove 30a. Exemplarily, as Figure 4 shown, the door seal 30 is provided with a limit groove 30a, and the stop structure 2111 is provided with a limit protrusion 2111a.

[0113] When the limit groove 30a is provided on the door seal 30, the specific position of the limit groove 30a is not limited. Exemplarily, as Figure 4 shown, the limit groove 30a can be formed at the included angle between the first connecting section 31 and the second connecting section 32; of course, the limit groove 30a can also be formed on the first connecting section 31 or the second connecting section 32.

[0114] After the door seal 30 is installed on the door body 20, the limit protrusion 2111a is snapped into the limit groove 30a. Therefore, it is beneficial to improve the reliability and stability of the installation of the door seal 30 on the door body 20.

[0115] Please refer to Figure 3 and Figure 4 In one embodiment, both the limit protrusion 2111a and the limit groove 30a extend along the axial direction of the door body 20.

[0116] It should be noted that the limiting groove 30a is integrally annular. In the axial section of the cylinder assembly, the cross-section of the limiting groove 30a is U-shaped, and the direction from the notch to the bottom of the limiting groove 30a is substantially parallel to the axial direction of the door body 20.

[0117] It can be understood that during the installation or disassembly of the door seal 30, displacement along the axial direction of the door body 20 is required. In this embodiment, since both the limiting protrusion 2111a and the limiting groove 30a extend along the axial direction of the door body 20, taking the installation of the door seal 30 as an example, when the door seal 30 displaces along the axial direction of the door body 20, the limiting protrusion 2111a can directly snap into the limiting groove 30a, that is, it is not necessary to adjust the door seal 30 in other directions to make the limiting protrusion 2111a snap into the limiting groove 30a. Thus, the installation or disassembly operation of the door seal 30 is more convenient and simple, which is conducive to improving the installation efficiency of the door seal 30.

[0118] In addition, during the process of the user replacing the door seal 30 by themselves, the replacement operation is relatively convenient and simple, which is easy for the user to implement. That is, on the premise that the operation experience of replacing the door seal 30 is better, the door seal 30 can be installed on the door body 20 more stably and reliably.
