[0036] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Please refer to Figures 1 to 6 together. An embodiment of the present application provides a laundry treatment device, which includes a cabinet and a drum assembly according to any one of the embodiments of the present application.

[0038] It should be noted that the laundry treatment device can be a washing machine, a washing and drying integrated machine, etc., which is not limited herein. Specifically, in the embodiment of the present application, a drum washing machine is taken as an example for illustration.

[0039] The cabinet can be understood as the external support structure of the laundry treatment device, and its specific shape is not limited. Exemplarily, the cabinet is generally a cube structure, and the cabinet is placed on the ground, and its stability is relatively better.

[0040] The drum assembly is disposed in the cabinet. That is to say, the cabinet can provide an installation basis for the drum assembly.

[0041] Please refer to Figures 1 to 6 together. An embodiment of the present application also provides a drum assembly, which is used for a laundry treatment device. The drum assembly includes a drum 10, a door body 20 and a door seal 30.

[0042] The drum 10 is used to perform functions such as washing, dehydrating or drying clothes on the clothes. The drum 10 has a laundry treatment cavity 11a and a laundry inlet 12a communicating with the laundry treatment cavity 11a. The clothes are washed and cared for in the laundry treatment cavity 11a, and the user can take and place the clothes through the laundry inlet 12a.

[0043] 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. Based on the drum 10 with such a structure, since it can hold the washing liquid by itself, therefore, an outer tub does not need to be sleeved outside the drum 10. During the process of washing clothes, after closing the laundry inlet 12a, it can effectively prevent the washing liquid from leaking out.

[0044] The door body 20 has an open state and a closed state.

[0045] In the open state, the laundry inlet 12a communicates with the outside. Thus, the user can take and place the clothes through the laundry inlet 12a.

[0046] In the closed state, the door body 20 cuts off the communication path between the laundry inlet 12a and the outside. Thus, it can effectively prevent the washing liquid in the laundry treatment cavity 11a from leaking out.

[0047] The door body 20 is connected to the drum 10. The door body 20 includes a protruding structure 22 and a frame 21 surrounding the protruding structure 22. The frame 21 is provided on the drum 10, and at least part of the protruding structure 22 protrudes from the side of the frame 21 close to the clothing inlet 12a.

[0048] There is no limitation on the connection manner between the frame 21 and the drum 10. Exemplarily, the cylinder assembly further includes a door hinge, and the frame 21 is installed 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.

[0049] 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.

[0050] There is no limitation on the specific type of the protruding structure 22. Exemplarily, the protruding structure 22 is a glass product.

[0051] At least part of the protruding structure 22 protrudes from the side of the frame 21 close to the clothing inlet 12a. That is to say, the protruding structure 22 extends beyond the surface of the frame 21 on the side close to the clothing inlet 12a.

[0052] 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, there are openings penetrating both axial sides of the frame 21, and the protruding structure 22 is arranged at the openings. 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 11a.

[0053] The door seal 30 is arranged at the clothing inlet 12a. That is to say, the drum 10 provides an installation base 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 will not separate from the clothing inlet 12a.

[0054] In the closed state, the door body 20 covers the drum 10, the protruding structure 22 extends into the clothing inlet 12a, 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 12a. That is to say, most of the area of the clothing inlet 12a 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 12a is sealed by the door seal 30.

[0055] When the door body 20 is in the closed state, the protruding structure 22 extends into the clothing inlet 12a. Thus, the sealing effect of the clothing inlet 10b can be improved.

[0056] 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 laundry 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 laundry 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 laundry inlet 10b, and this gap is sealed by the door seal 30. Thus, it is beneficial to further improve the sealing effect of the laundry inlet 12a.

[0057] The door seal 30 can be made of various flexible materials, such as rubber, silica gel, 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 laundry inlet 12a and the side wall of the protruding structure 22 respectively, which is beneficial to improving the sealing effect of the laundry inlet 12a.

[0058] In the related art, the laundry treatment device includes a drum and a door body. In order to prevent the washing liquid from leaking out during the operation of the drum washing machine, a door seal is required between the drum and the door body. Generally, a part of the door body is made of glass products, and the door body covers the laundry inlet through the glass products. The door seal is generally connected to the glass products. However, since it is not convenient to install other components on the glass products, the installation of the door seal is also relatively complex.

[0059] In the cylinder assembly of the embodiment of the present application, the door seal 30 is provided at the laundry inlet 12a, that is, the door seal 30 is connected to the drum 10. The door seal 30 does not need to be installed on the door body 20, and thus does not need to be connected to the glass products (such as the protruding structure 22) on the door body 20. The structure of the drum 10 for forming the laundry inlet 12a generally does not use glass products. Thus, it is beneficial to reduce the installation difficulty of the door seal 30.

[0060] In the related art, the cylinder assembly of the laundry 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 laundry treatment device and 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 laundry inlet of the drum at the same time. In order to make the door body meet the effect of sealing both the opening of the outer cylinder and the laundry inlet of the drum at the same time, 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 ensure that the washing liquid cannot flow out from the laundry 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.

[0061] 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 cavity 11a. 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 12a) to effectively improve the problem of leakage of the washing liquid. The design of the irregular structure of the traditional door seal in the form of folds can be simplified, which is beneficial to improving the problem of dirt and scale 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 12a, it is beneficial to reduce the probability of the washing liquid leaking into the gap between the door seal 30 and the protruding structure 22 or between the door seal 30 and the laundry inlet 12a. 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 an irregular structure in the form of folds, which is beneficial to improving the problem of dirt and scale accumulation in the door seal 30.

[0062] Further, in the laundry treatment equipment in the related art, the door body is installed on the cabinet, 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.

[0063] 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 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 12a 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 12a 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 12a on the premise of facilitating the rotation of the drum 10.

[0064] Please refer to Figure 3 、 Figure 4 and Figure 6 In one embodiment, the door seal 30 includes a connecting portion 31 and a sealing portion 32. At least part of the connecting portion 31 is arranged on the side wall of the laundry inlet 12a, and the sealing portion 32 is located inside the laundry inlet 12a. In the closed state, the protruding structure 22 is in sealing cooperation with the sealing portion 32.

[0065] The connecting portion 31 and the sealing portion 32 can be an integral structure.

[0066] The door seal 30 is relatively stably mounted on the drum 10 through the connecting portion 31. The connecting portion 31 extends along the circumferential direction of the laundry inlet 12a and is presented as a ring shape, such as a circular ring shape.

[0067] The sealing portion 32 is located on the inner side of the connecting portion 31 along the radial direction of the laundry inlet 12a and also extends along the circumferential direction of the laundry inlet 12a. The sealing portion 32 is also presented as a ring shape, such as a circular ring shape. The sealing portion 32 is used to seal the gap between the protruding structure 22 and the laundry inlet 12a.

[0068] In this embodiment, the sealing portion 32 and the protruding structure 22 achieve the first - stage sealing. The sealing portion 32 can achieve an interference sealing fit with the side wall of the protruding structure 22. On the one hand, it can better seal the laundry inlet 12a; on the other hand, the washing liquid will basically only contact the sealing portion 32, which is beneficial to improving the problem of dirt accumulation of the door seal 30.

[0069] Please refer to Figure 3 and Figure 4 , in one embodiment, the sealing portion 32 has a connecting end 32a and a free end 32b. The sealing portion 32 is connected to the connecting portion 31 through the connecting end 32a. The free end 32b extends radially inward along the laundry inlet 12a, and the protruding structure 22 and the free end 32b are in sealing fit.

[0070] It can be understood that in the axial section of the cylinder assembly, the cross - section of the sealing portion 32 is strip - shaped, and the connecting end 32a and the free end 32b are respectively the opposite ends of the strip - shaped cross - section.

[0071] From the overall perspective of the sealing portion 32, the free end 32b is the inner - ring end face of the sealing portion 32 along the radial direction of the laundry inlet 12a, and the connecting end 32a is the outer - ring end face of the sealing end along the radial direction of the laundry inlet 12a.

[0072] In this embodiment, the sealing portion 32 is generally in a ring shape, that is, the dimension of the sealing portion 32 along the axial direction of the laundry inlet 12a is relatively small, so that it can relatively easily generate elastic deformation. Thus, it is convenient to achieve the interference sealing fit between the free end 32b and the protruding structure 22.

[0073] Please refer to in combination with Figures 3 to 6 , in one embodiment,

[0074] During the process of the door body 20 switching from the open state to the closed state, the protruding structure 22 applies a force to the free end 32b and can drive the free end 32b to deflect relative to the connecting end 32a.

[0075] Please refer to Figure 6, C’ shows the position of the sealing part 32 when the door body 20 is in the open state, and C shows the position of the sealing part 32 when the door body 20 is in the closed state.

[0076] During the process of the door body 20 switching from the open state to the closed state, after the protruding structure 22 rotates to contact the free end 32b, the door body 20 continues to move in the direction of switching to the closed state. The acting force exerted by the protruding structure 22 on the free end 32b is towards the inside of the clothing treatment cavity 11a. Therefore, it is convenient for the free end 32b to deflect away from one end of the frame 21 relative to the connecting end 32a under the action of this acting force. At the same time, the free end 32b also always remains in contact with the protruding structure 22. That is to say, during the process of the door body 20 switching from the open state to the closed state, by the free end 32b generating a deflection deformation relative to the connecting end 32a, it can not only effectively reduce the closing resistance during the process of switching the door body 20 to the closed state, but also enable a good sealing effect to be formed between the free end 32b and the protruding structure 22 after the door body 20 is switched to the closed state.

[0077] Along the axial direction of the clothing inlet 12a, the connecting end 32a is closer to the frame 21 than the free end 32b. The included angle between the extending direction of the sealing part 32 and the axial direction of the clothing inlet 12a is not limited. As long as the protruding structure 22 can achieve a sealing fit with the free end 32b when the door body 20 is in the closed state.

[0078] It should be noted that this included angle can be an acute angle, a right angle or an obtuse angle. Preferably, the range of this included angle is 60° to 120°. For example, it can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, etc. More preferably, this included angle is 90°.

[0079] Taking the side of the sealing part 32 close to the clothing treatment cavity 11a as a reference, on this side, if the included angle between the sealing part 32 and the axial direction of the clothing inlet 12a is an obtuse angle that is too large, when the door body 20 is switched to the closed state, the extrusion force received by the door body 20 may be relatively large, which is not convenient for the user to operate and close the door body 20; if the included angle between the sealing part 32 and the axial direction of the clothing inlet 12a is an acute angle that is too small, it may cause the sealing part 32 and the protruding structure 22 not to achieve a tight fit, resulting in poor sealing performance.

[0080] In this embodiment, the included angle between the extending direction of the sealing part 32 and the axial direction of the clothing inlet 12a is limited to between 60° and 120°, and even more preferably limited to 90°, so as to be beneficial to taking into account the labor-saving when switching the door body 20 to the closed state and the sealing effect of the sealing part 32 on the gap between the protruding structure 22 and the side wall of the clothing inlet 12a.

[0081] In some embodiments, please refer to Figure 4 , on the side of the sealing portion 32 facing the laundry treatment cavity 11a, the plane is perpendicular to the axis of the laundry inlet 12a, and along the radial direction of the laundry treatment opening 12a inward, the side of the sealing portion 32 facing away from the laundry treatment cavity 11a gradually approaches the laundry treatment cavity 11a. That is to say, the dimension of the connecting end 32a along the axis of the laundry inlet 12a is greater than the dimension of the free end 32b along the axis of the laundry inlet 12a, that is, the thickness dimension of the connecting end 32a is larger than the thickness dimension of the free end 32b. Thus, the deflection of the sealing portion 32 is more stable.

[0082] In addition, an obtuse angle is formed between the side of the sealing portion 32 facing away from the laundry treatment cavity 11a and the connecting portion 31 (the second connecting section 312). After the protruding structure 22 presses against the free end 32b, the sealing portion 32 is more likely to generate elastic deformation and deflection, and the protruding structure 22 is more likely to be pushed into the laundry inlet 12a.

[0083] Please refer to Figure 3 and Figure 4 , in one embodiment, the drum 10 includes a drum body 11 and a cylinder 12 provided on the drum body 11. The drum body 11 encloses to form a laundry treatment cavity 11a, and the cylinder 12 encloses to form a laundry inlet 12a.

[0084] The cylinder 12 and the drum body 11 can be an integral structure. Of course, the two can also be a split structure.

[0085] It can be understood that the drum body 11 has a connection position, and the cylinder 12 is connected to the connection position. That is, the surface of the cylinder 12 protrudes relative to the surface of the drum body 11 at the connection position.

[0086] The door seal 30 is sleeved on the cylinder 12, and the connecting portion 31 elastically abuts against both the inner side wall and the outer side wall of the cylinder 12. Thus, the connecting portion 31 is equivalent to being wrapped around the cylinder 12, thereby improving the installation stability of the door seal 30 on the cylinder 12.

[0087] It should be noted that the area of the elastic abutment between the connecting portion 31 and the inner side wall of the cylinder 12 or the outer side wall of the cylinder 12 is not limited. A larger area of elastic abutment has a relatively better clamping effect, but during the installation of the door seal 30, the frictional resistance between the connecting portion 31 and the cylinder 12 is also relatively large, that is, the door seal 30 is relatively difficult to install; a smaller area of elastic abutment has a relatively poor clamping effect, but the door seal 30 is relatively simple to install during the installation process.

[0088] Please refer to Figure 3 and Figure 4, in one embodiment, the connecting portion 31 has an annular groove 31a, and one end of the column 12 away from the laundry treatment cavity 11a is disposed in the annular groove 31a. That is to say, a part of the connecting portion 31 is located inside the column 12 in the radial direction of the laundry inlet 12a, and a part is located outside the column 12 in the radial direction of the laundry inlet 12a.

[0089] The connecting portion 31 can be understood as covering the side wall of the column 12. In this embodiment, since the surface of the column 12 protrudes relative to the cylinder body 11 at the connection position, it is convenient to install the connecting portion 31.

[0090] Please refer to Figure 5 and Figure 6 , in one embodiment, in the closed state, the frame and the connecting portion 31 are in sealing fit. That is to say, in the closed state, the connecting portion 31 is sealingly clamped between one end of the column 12 away from the laundry treatment cavity 11a and the frame 21.

[0091] In the open state, the frame 21 can be separated from the connecting portion 31.

[0092] Specifically, as Figure 4 and Figure 6 shown, the sealing portion 32 and the protruding structure 22 achieve the first seal, and the connecting portion 31 and the frame 21 achieve the second seal. Through at least two sealing structures, the sealing effect of the laundry inlet 12a is further improved, and thus the washing liquid is prevented from leaking out from the laundry inlet 12a.

[0093] Please refer to Figure 3 and Figure 4 , in one embodiment, one end of the column 12 away from the laundry treatment cavity 11a forms a limiting portion 12b, and the limiting portion 12b is located in the annular groove 31a.

[0094] Specifically, the annular groove 31a has a variable diameter section. Taking the direction from the laundry inlet 12a to the laundry treatment cavity 11a and parallel to the axial direction of the laundry inlet 11a as the reference direction, along the reference direction, the dimension of the variable diameter section in the radial direction of the laundry inlet 12a gradually decreases, and the limiting portion 12b is located in the variable diameter section.

[0095] One end of the column 12 close to the laundry treatment cavity 11a is a transition fit end 12c, and the column 12 is connected to the cylinder body 11 through the transition fit end 12c.

[0096] It can be understood that if the door seal 30 falls off from the column 12, a displacement from the transition fit end 12c to the limiting portion 12b direction is required.

[0097] The dimension of the limiting portion 12b in the radial direction of the clothing inlet 12a is greater than the dimension of the transition fitting end 12c in the radial direction of the clothing inlet 12a, and the connecting portion 31 elastically abuts against the outer side wall of the transition fitting end 12c.

[0098] The limiting portion 12b is arranged in the annular groove 31a and is in snap-fit with the stepped diameter section.

[0099] That is to say, if the door seal 30 is to fall off from the column 12, the connecting portion 31 needs to first release the elastic abutment against the outer side wall of the transition fitting end 12c. And because the limiting portion 12b is also in snap-fit with the stepped diameter section of the annular groove 31a, during the process of the door seal 30 falling off from the column 12, the connecting portion 31 also needs to generate a certain deformation to satisfy the separation of the limiting portion 12b from the stepped diameter section of the annular groove 31a. Thus, in this embodiment, the door seal 30 needs to be subjected to a relatively large external force to possibly fall off from the column 12, that is, the door seal 30 has better installation stability and higher reliability on the column 12.

[0100] It should be noted that there is no limitation on the way of forming the limiting portion 12b on the column 12. In some embodiments, please refer to Figure 3 and Figure 4 , one end of the column 12 away from the clothing treatment cavity 11a is wound outward to form the limiting portion 12b. That is to say, the limiting portion 12b is directly formed when the column 12 is molded. During the production process, a bending machine can be used to make one end of the column 12 produce a winding effect to form the limiting portion 12b. Thus, the way of forming the limiting portion 12b is relatively simple and easy to implement.

[0101] It can be understood that the wall thickness of the limiting portion 12b in this embodiment can be the same as the wall thickness of the rest of the column 12.

[0102] In other embodiments, it can also be that the outer side wall of one end of the column 12 away from the clothing treatment cavity 11a protrudes outward in the radial direction of the clothing inlet 12a to form the limiting portion 12b. With the limiting portion 12b having such a structure, the column 12 can be produced by an injection molding method.

[0103] Please refer to Figure 3 and Figure 4 , in one embodiment, taking the direction along the clothing inlet 12a into the clothing treatment cavity 11a and parallel to the axial direction of the clothing inlet 11a as the reference direction, along the reference direction, the radial dimension of the inner wall of the connecting portion 31 gradually decreases. Specifically, the radial dimension of the inner wall of the second connecting section 312 gradually decreases.

[0104] It should be noted that the second connecting section 312 is generally annular. That is to say, along the reference direction, the inner diameter of the second connecting section 312 gradually decreases. In the axial section of the cylinder assembly, the extending direction of the section of the second connecting section 312 is inclined relative to the axial direction of the clothing inlet 12a. Thus, during the process of the door body 20 switching to the closed state, it is convenient for the protruding structure 22 of the door body 20 to extend into the clothing inlet 12a and achieve a sealing fit with the door seal 30.

[0105] Please refer to Figure 3 and Figure 4 , in one embodiment, along the radial direction of the clothing inlet 12a, the size of the annular groove 31a at the end far from the clothing treatment cavity 11a is larger than the size of the annular groove 31a at the end close to the object treatment cavity.

[0106] It should be noted that here it refers to the state where the door seal 30 is not installed on the column 12, and the annular groove 31a already has this feature.

[0107] It can be understood that the presence of the limiting portion 12b ensures the stability and reliability of the door seal 30 after it is installed on the column 12. However, during the installation of the door seal 30 on the column 12, the limiting portion 12b will generate a certain resistance to the installation of the column 12, increasing the installation difficulty of the door seal 30.

[0108] In this embodiment, when the door seal 30 is not installed on the column 12, the size of the annular groove 31a at the end far from the clothing treatment cavity 11a will be larger than the size of the annular groove 31a at the end close to the object treatment cavity, thereby improving the adaptability of the annular groove 31a to the limiting portion 12b and facilitating the reduction of the installation difficulty of the door seal 30.

[0109] In other embodiments, when the door seal 30 is not installed on the column 12, along the axial direction of the door seal 30, the size of the annular groove 31a in the radial direction of the clothing inlet 12a can also remain consistent. That is, after the door seal 30 is installed on the column 12, one end of the annular groove 31a far from the clothing treatment cavity 11a is expanded under the action of the limiting portion 12b.

[0110] Please refer to Figure 3 and Figure 4 , in one embodiment, the connecting portion 31 includes a first connecting section 311, a second connecting section 312, and a transition connecting section 313. The first connecting section 311 is arranged on the outer side surface of the column 12, the second connecting section 312 is arranged on the inner side surface of the column 12, the transition connecting section 313 is wrapped around the limiting portion 12b, and both ends of the transition connecting section 313 are respectively connected to the first connecting section 311 and the second connecting section 312, and the three jointly define and form the annular groove 31a.

[0111] The first connecting section 311, the second connecting section 312, and the transition connecting section 313 can be of an integral structure.

[0112] Here, the connecting end 32a of the sealing portion 32 is connected to the second connecting section 312. When the door body 20 is in the closed state, the frame 21 is in sealing abutment with the transition connecting section 313.

[0113] In the axial section of the cylinder assembly, the cross-section of the transition connecting section 313 can be arc-shaped, so as to facilitate the design of the dimension of the end of the annular groove 31a far from the laundry treatment cavity 11a to be larger than the dimension of the end of the annular groove 31a close to the laundry treatment cavity. That is, it is convenient for the annular groove 31a to form a variable diameter section.

[0114] The cross-sections of the first connecting section 311 and the second connecting section 312 can both extend linearly. Thus, it is convenient for the first connecting section 311 to elastically abut against the outer side wall of the column 12, and it is convenient for the second connecting section 312 to elastically abut against the side wall of the laundry inlet 12a.

[0115] The cylinder assembly further includes a connecting ring 40, and the connecting ring 40 is sleeved on the outer periphery of the first connecting section 311.

[0116] The specific type of the connecting ring 40 is not limited. For example, it can be a clamp.

[0117] It can be understood that the first connecting section 311 is integrally in an annular structure. After the connecting ring 40 is sleeved on the outer side of the first connecting section 311, it is equivalent to pressing the first connecting section 311 against the column 12 along the radial direction of the laundry inlet 12a. Thus, it is beneficial to further improve the installation stability and reliability of the door seal 30 on the column 12.

[0118] Please refer to Figure 3 and Figure 4 , in one embodiment, the connecting portion 31 further includes a limiting section 314. One end of the limiting section 314 is arranged at the end of the first connecting section 311 close to the laundry treatment cavity 11a and is arranged at an angle with the first connecting section 311, and the connecting ring 40 is arranged at the connection of the first connecting section 311 and the limiting section 314.

[0119] The limiting section 314 and the first connecting section 311 can be an integrally formed structure.

[0120] The specific angle of the angle between the first connecting section 311 and the limiting section 314 is not limited. It can be understood that in the axial section of the cylinder assembly, the cross-section of the limiting section 314 can be strip-shaped, one end of the limiting section 314 is connected to the first connecting section 311, and the other end extends radially outward along the laundry inlet 12a.

[0121] A corner is formed at the connection between the first connecting section 311 and the limiting section 314. The connecting ring 40 is disposed at the corner. The corner has a certain limiting effect on the connecting ring 40, making the setting position of the connecting ring 40 on the connecting portion 31 more stable.

[0122] Please refer to Figure 3 and Figure 4 , in one embodiment, the included angle between the first connecting section 311 and the limiting section 314 is less than or equal to 90 degrees. For example, it can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, and so on.

[0123] The first connecting section 311 and the limiting section 314 can interact with each other, and both can have a certain clamping effect on the connecting ring 40. Thus, the installation and cooperation stability and reliability of the connecting ring 40 and the connecting portion 31 are further improved.
