Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0061] This application provides a sealing component 10 and a clothing processing device 100, wherein the clothing processing device 100 can be a device for drying clothing. It is understood that the clothing processing device 100 can be a clothing processing device directly placed on the ground or a display surface, or it can be a wall-mounted or countertop clothing processing device 100. The clothing processing device 100 has a clothing processing main unit, a housing of the clothing processing main unit, and a rotating drum 30 for holding clothing inside the housing. The housing also has a clothing loading / unloading port for convenient user access. The clothing processing device 100 also has a movable door, which is located outside the clothing processing main unit and can move relative to the clothing loading / unloading port to open or close the loading / unloading port.

[0062] On the side of the garment handling device 100 opposite to the garment loading / unloading port, the garment handling device 100 also includes a back panel 20, which is part of the outer casing. The rotating drum 30 can rotate relative to the back panel 20 to facilitate the handling of garments located inside the rotating drum 30. Therefore, in order to prevent the drying hot air from leaking out from the gap between the rotating drum 30 and the back panel 20 during the conveying process, an axial sealing structure is generally required here.

[0063] Traditional axial sealing structures utilize the flexibility and elasticity of materials such as felt, foam, and rubber to seal the gap between the rotating cylinder 30 and the back plate 20. However, experience has shown that these elastic materials have poor sealing performance and exhibit wear and aging after prolonged use, gradually reducing their sealing effectiveness. Furthermore, these materials are prone to wrinkling during installation, resulting in poor surface flatness and further affecting the sealing performance.

[0064] To at least partially improve the above-mentioned problems, this application provides a sealing component 10.

[0065] Figure 1 This is a schematic diagram of the sealing assembly provided in an embodiment of this application. Figure 2 This is a cross-sectional view of the sealing assembly provided in an embodiment of this application. Figure 3 for Figure 2 Enlarged view of the structure of region A in the middle.

[0066] The sealing assembly 10 described above is used in a garment processing device 100 with a drying function, and the garment processing device 100 has a rotating drum 30. The sealing assembly 10 is arranged between the back panel 20 and the rotating drum 30.

[0067] Please see Figure 1 The sealing assembly 10 includes a sealing bracket 1 and an elastic element 2, wherein the sealing bracket 1 can be fixed to the side of the back plate 20 facing the rotating cylinder 30; the elastic element 2 is provided on the side of the sealing bracket 1 facing the rotating cylinder 30.

[0068] Specifically, the orthographic projection of the sealing bracket 1 onto the rotating cylinder 30 along the axis is a closed shape.

[0069] The axial direction of the sealing bracket 1 is parallel to the axial direction of the rotating cylinder 30. The orthographic projection of the sealing bracket 1 in the axial direction of the rotating cylinder 30 is consistent with the orthographic projection of the sealing bracket 1 in the axial direction. The orthographic projection of the elastic element 2 in the axial direction of the sealing bracket 1 is also a closed shape, and the orthographic projection of the elastic element 2 in the axial direction of the sealing bracket 1 at least partially coincides with the orthographic projection of the sealing bracket 1 in its axial direction, and the overlapping part is also a closed shape.

[0070] The projection is a closed shape, which can prevent airflow and heat from leaking along the periphery of the sealing bracket 1 and the elastic element 2.

[0071] With the above-mentioned structural constraints, it can be ensured that when the sealing bracket 1 is installed on the back plate 20 and the elastic member 2 is rotatably abutting against the side of the rotating cylinder 30 near the sealing bracket 1, a closed space can be formed between the rotating cylinder 30 and the back plate 20, ensuring that the airflow can enter the rotating cylinder 30 along a set path.

[0072] When the sealing assembly 10 is assembled onto the garment processing equipment 100, the end of the rotating drum 30 that is axially close to the sealing bracket 1 can abut against the elastic element 2. At this time, the sealing bracket 1 can generate a recoverable elastic deformation under the squeezing force generated when the rotating drum 30 abuts against the elastic element 2, so as to improve the adaptability to the jumping and eccentric actions generated during the operation of the rotating drum 30, improve the sealing effect of the sealing assembly 10, and improve the reliability and stability of the sealing assembly 10 between the back panel 20 and the rotating drum 30.

[0073] In addition, the aforementioned sealing bracket 1 can also compensate for the wear caused by the mutual rotation between the rotating cylinder 30 and the elastic element 2, thereby forming a stable and well-sealed axial sealing structure.

[0074] Specifically, the elastic element 2 can be made of stacked felt, rubber, and foam. In this embodiment, taking the elastic element 2 as being made of felt as an example, the structure and assembly process of the elastic element 2 will be specifically described. Felt has a dense fiber structure, which can effectively fill gaps and block gas passage. It also has good wear resistance and thermal stability, can withstand long-term friction, and is not easily damaged. The sealing bracket 1 can provide good elastic deformation, so that the felt can closely fit the moving parts during dynamic sealing, making up for the possible sealing deficiencies of the felt. The combination of the two can effectively improve the sealing effect, reduce the leakage of hot air during drying, improve drying efficiency, and also prevent impurities such as lint from entering the garment processing equipment 100.

[0075] The elastic element 2 described above can be fixed to the sealing bracket 1 by adhesive bonding. In this case, the elastic element 2 is a felt with adhesive backing. In other embodiments, the elastic element 2 can also be a sponge or rubber component with adhesive backing, etc.

[0076] In addition, the aforementioned sealing assembly 10 separates the elastic element 2 from the rear panel 20 structure. Compared with direct installation on the rear panel 20, installing the elastic element 2 on the sealing bracket 1 can effectively reduce the installation difficulty of the elastic element 2 and improve the defects of the elastic element 2 being prone to wrinkling and uneven surface during installation to a certain extent.

[0077] For operators, the limited operating space when installing the elastic element 2 on the back panel 20 makes it difficult to ensure a perfect fit between the elastic element 2 and the back panel 20, easily leading to wrinkles and affecting the flatness and sealing effect of the elastic element 2 surface. Furthermore, if there are deviations in the adhesive placement or unevenness when fixing the elastic element 2 to the back panel 20, it is difficult for operators to adjust it. However, when adhesiveing ​​the elastic element 2 to the sealing bracket 1, the smaller size of the sealing bracket 1 compared to the back panel and the unrestricted operating environment allow for greater operating space. This facilitates adjustments to the installation position and surface shape of the elastic element 2, resulting in a smoother adhesive finish. Additionally, the smoother surface of the sealing bracket 1 compared to the back panel 20 provides a better mounting surface for the elastic element 2, preventing wrinkles and deformation caused by the mounting surface.

[0078] Please see Figure 1 In this embodiment, the sealing bracket 1 is a ring structure, and the elastic element 2 is a ring structure fixed to one axial side surface of the sealing bracket 1. Of course, in other embodiments, the sealing bracket 1 can also be set as a rectangle, ellipse, or other conventional closed graphic structure as needed, and the shape and size of the elastic element 2 can be adjusted accordingly.

[0079] The sealing component 10 provided in this application embodiment can also be found in [the following text is missing from the original] Figure 2 and Figure 3 As can be seen, the sealing bracket 1 includes a connected sealing element 11 and a positioning element 12. The positioning element 12 is located on one side of the sealing element 11 in the width direction and extends toward the side opposite to the elastic element 2. The positioning element 12 is used to fix it to the back plate 20.

[0080] The sealing element 11 and the positioning element 12 are connected to form an L-shaped cantilever beam structure. When the sealing bracket 1 is squeezed or pushed by an external force from the direction of the elastic element 2, the sealing bracket 1 with the cantilever beam structure can bend under the action of the external force. This bending deformation allows the sealing element 11 and the positioning element 12 in the sealing bracket 1 to bear and disperse the extrusion force as a whole, avoiding damage to the sealing bracket 1 under the action of the external force. When the external force is removed, the sealing bracket 1 can return to its original shape through its own elastic restoring force, so that the sealing assembly 10 can maintain a relatively reliable and stable sealing performance.

[0081] In the axial section of the sealing bracket 1, the positioning element 12 is connected to the sealing element 11 and remains perpendicular or approximately perpendicular.

[0082] Specifically, the aforementioned positioning element 12 can be disposed radially on the outer or inner side of the seal 11. Please refer to... Figure 3The positioning element 12 is connected to the outer side of the sealing element 11 in the radial direction to form an integral sealing bracket 1 structure. In the thickness direction of the sealing element 11, the positioning element 12 and the elastic element 2 are located on opposite sides of the sealing element 11.

[0083] Please see Figure 3 The sealing assembly 10 also includes a sealing ring 3, which is located on the side of the sealing bracket 1 facing the rear back plate 20. That is, the sealing ring 3 is located on the side of the positioning member 12 away from the sealing member 11. The sealing ring 3 has a structure that matches the shape of the sealing bracket 1; when the sealing bracket 1 is annular, the sealing ring 3 is also annular.

[0084] The sealing bracket 1 is fixed to the back plate 20. The sealing ring 3 has opposite sides that contact the sealing bracket 1 and the back plate 20, respectively. Under pressure, the sealing ring 3 undergoes elastic deformation, resulting in a tight fit between the sealing ring 3 and the opposite surfaces of the sealing bracket 1 and the back plate, forming a well-sealed annular sealing band. This further improves the sealing effect of the sealing assembly 10 and reduces the possibility of airflow and heat loss through the assembly gap between the sealing bracket 1 and the back plate 20. For the garment processing equipment 100, this sealing assembly 10 can further improve the drying performance of the garment processing equipment 100.

[0085] The aforementioned sealing bracket 1 is connected to the rear back plate 20 via a positioning member 12. The positioning member 12 has a recessed groove 121 on the side facing away from the sealing member 11 for accommodating the aforementioned sealing ring 3. When the sealing bracket 1 is fixedly installed on the rear back plate 20, the sealing ring 3 abuts against the rear back plate 20.

[0086] When the sealing ring 3 is installed in the slot 121, it will be compressed to a certain extent, resulting in elastic deformation. When the sealing bracket 1 is installed on the back plate 20, it will further compress the sealing ring 3 and cause the sealing ring 3 to elastically deform and keep it tightly fitted to the back plate 20, so as to prevent airflow and heat in the enclosed space from leaking out from the gap between the sealing bracket 1 and the back plate 20.

[0087] Please see Figure 3 The aforementioned sealing bracket 1 is also provided with mounting holes 122 for installing fasteners, and the back plate 20 is provided with fixing holes that mate with the mounting holes 122. The sealing bracket 1 can be fixedly installed on the back plate 20 by fasteners passing through the mounting holes 122 and the fixing holes. Figure 3 In the drawing, neither the fasteners nor the fixing holes are shown.

[0088] Fasteners can be screws or other fastening structures with similar fastening functions.

[0089] Specifically, the mounting hole 122 is formed on the positioning member 12 and is provided along the extending direction of the positioning member 12. The positioning member 12 protrudes on the side near the seal member 11 and forms a columnar connecting post, on which the mounting hole 122 is provided. One end of the connecting post is connected to the seal member 11.

[0090] The aforementioned connecting posts with mounting holes 122 are multiple and spaced apart along the extension direction of the sealing bracket 1, thereby ensuring that each position of the sealing bracket 1 can be firmly connected and fixed to the back plate 20. Furthermore, this ensures that each position of the sealing bracket 1 provides uniform compressive force to the sealing ring 3, guaranteeing that the sealing ring 3 fits tightly against the back plate 20 across the entire contact surface.

[0091] Figure 4 This is a schematic diagram of the structure of the sealing bracket in the sealing assembly provided in the embodiments of this application. Figure 5 for Figure 4 Enlarged view of the structure of region B in the middle.

[0092] Please see Figure 4 and Figure 5 The sealing bracket 1 includes a sealing element 11 and a positioning element 12 that are fixedly connected. The side of the sealing element 11 facing away from the positioning element 12 forms an annular assembly surface for mounting the elastic element 2 (the annular assembly surface faces the rotating cylinder 30). The elastic element 2 can be fixed to the annular assembly surface by adhesive.

[0093] In order to further reinforce and limit the elastic element 2 and prevent the elastic element 2 from being displaced or detached from the designed installation position as the rotating drum 30 rotates, in some embodiments, the sealing element 11 is provided with a first limiting element 111 and a second limiting element 112 that are spaced apart on the side facing the rotating drum 30, and an installation groove 113 for installing the elastic element 2 is defined between the first limiting element 111 and the second limiting element 112.

[0094] Specifically, when the sealing bracket 1 has an annular structure, the first limiting member 111 and the second limiting member 112 are arranged radially spaced apart along the sealing bracket 1, with the second limiting member 112 located radially outside the first limiting member 111. A portion of the inner wall of the mounting groove 113 is formed on the surface of the first limiting member 111 facing the second limiting member 112, and a portion of the inner wall of the mounting groove 113 is formed on the surface of the second limiting member 112 facing the first limiting member 111. The mating surface between the first limiting member 111 and the second limiting member 112 forms a portion of the bottom wall of the mounting groove 113. The two opposing inner walls and the bottom wall are connected to form the mounting groove 113.

[0095] In some embodiments, the first limiting member 111 and the second limiting member 112 are both annular structures and nested together to form an annular mounting groove 113. In other similar embodiments, one of the first limiting member 111 and the second limiting member 112 is an annular structure, and the other is composed of a plurality of arc-shaped sidewalls or block-shaped sidewalls arranged in annular intervals.

[0096] Please see Figure 4 and Figure 5 In the figure, the first limiting member 111 is a ring structure, and the second limiting member 112 is a block structure arranged in a ring at intervals.

[0097] When the sealing bracket 1 is a non-annular structure, the shape of the first limiting member 111 will also be adjusted accordingly, but its orthogonal projection in the axial direction will always remain a closed shape.

[0098] In other similar embodiments, the second limiting member 112 may also be a closed ring or other similar shape. In this case, the orthogonal projection of the second limiting member 112 in the axial direction may also be a closed shape.

[0099] In order to further improve the elastic deformation and recovery ability of the sealing bracket 1, in addition to improving the material and selecting a material with a higher elastic modulus to make the sealing bracket 1, the structure of the sealing bracket 1 can also be optimized.

[0100] Specifically, a groove-shaped cross section can be added to the sealing element 11 of the sealing bracket 1.

[0101] Please see Figure 4 and Figure 5 The sealing element 11 is provided with through grooves 114 that penetrate both sides of the sealing element 11 in the thickness direction. There are multiple through grooves 114, which are evenly spaced along the circumference of the sealing bracket 1.

[0102] When the seal 11 is an annular structure and the positioning member 12 is located on the radially outer side of the seal 11, the through groove 114 penetrates the radially inner side of the seal 11 and is arranged at intervals with the positioning member 12 in the radial direction of the seal 11. Multiple through grooves 114 are arranged in an array on the seal 11 in an annular pattern.

[0103] In other similar embodiments, when the positioning member 12 is located radially inside the seal member 11, the through groove 114 penetrates the outer radial direction of the seal member 11 and is arranged radially spaced from the positioning member 12 in the seal member 11.

[0104] Specifically, in the radial direction of the seal 11, the length of the groove 114 is substantially the same as half the width of the seal 11. In other similar embodiments, the length of the groove 114 is slightly less than half the width of the seal 11.

[0105] Please see Figure 5 The portion of the aforementioned through groove 114 that penetrates the mounting groove 113.

[0106] The positioning member 12 of the sealing bracket 1 is also provided with a reinforcing rib 123, which is located on the side of the positioning member 12 facing away from the sealing member 11. The reinforcing rib 123 is used to enhance the strength of the positioning member 12.

[0107] Figure 6 This is a structural schematic diagram of the sealing bracket in the sealing assembly provided in this application embodiment from another angle. Figure 7 for Figure 6 Enlarged view of the structure of region C.

[0108] The aforementioned sealing element 11 also has a protruding contact element 13 on the side facing the rear back plate 20, spaced apart from the positioning element 12. When the sealing bracket 1 is installed on the rear back plate 20, there is a gap between the contact element 13 and the rear back plate 20. This gap is a reserved space for the ultimate deformation of the sealing bracket 1. The contact element 13 can act as a limit for the ultimate deformation of the sealing bracket 1, preventing the sealing bracket 1 from undergoing excessive deformation and affecting the sealing performance of the sealing assembly 10.

[0109] Along the axial direction of the rotating drum 30 or the circumferential direction of the sealing bracket 1, the length of the contact member 13 is less than the length of the positioning member 12, and the difference between the two is the aforementioned gap.

[0110] On the annular sealing bracket 1, the contact element 13 is disposed radially inward of the seal element 11. See also... Figure 5 and Figure 7 On the radial orthographic projection of the sealing bracket 1, the projection of the contact 13 overlaps with the projection of the through groove 114. The through groove 114 is provided through the contact 13 and divides the contact 13 into multiple arc-shaped plate structures.

[0111] The number of contact elements 13 is the same as the number of through slots 114. Any two adjacent through slots 114 separate an independent arc-shaped contact element 13. The side of any contact element 13 closest to the through slot 114 is folded inward or outward toward the seal 11 to form a reinforcing structure. This reinforcing structure helps to enhance the strength of the contact element 13.

[0112] In the axial direction of the sealing bracket 1, the orthographic projection of the contact 13 is located inside the orthographic projection of the positioning member 12.

[0113] Of course, in other similar embodiments, when the positioning member 12 is connected to the radial inner wall of the sealing member 11, the contact member 13 is located outside the axial orthogonal projection of the positioning member 12 on the sealing bracket 1.

[0114] It is understood that the sealing component 10 provided in this application embodiment reduces the installation difficulty by adjusting the structure; at the same time, since the sealing bracket 1 can provide a certain axial elastic deformation compensation for the rotating cylinder 30, a stable and well-sealed axial sealing structure can be formed to improve the sealing performance of the sealing component 10 located at the back plate 20 and reduce the possibility of sealing failure.

[0115] This application also provides a garment processing device 100, which includes the sealing component 10 described in any of the above claims.

[0116] Figure 8 This is a partially exploded view of the clothing processing equipment provided in the embodiments of this application. Figure 9 This is a partial structural cross-sectional view of the garment processing equipment provided in the embodiments of this application. Figure 10 for Figure 9 Enlarged view of the structure of region D in the middle. Figure 11 This is a structural schematic diagram of the garment processing device provided in an embodiment of this application from another angle. Figure 12 for Figure 11 Enlarged view of the structure of region E in the middle.

[0117] Please see Figure 8 and Figure 9 The garment processing device 100 includes a housing and a rotating drum 30, wherein the other structural components of the housing, except for the back panel 20, are not shown in the diagram. The back panels 20 of the rotating drum 30 are located on opposite sides of the aforementioned sealing assembly 10 in the axial direction.

[0118] The hot airflow within the garment processing equipment 100 is typically generated in the base portion of the equipment. A fan is installed on the area of ​​the back panel 20 opposite to the base, and an exhaust port 22 is provided on the area opposite the rotating drum 30. One end of the fan is connected to the internal space of the base, and the other end is connected to the exhaust port 22. An air inlet 312 is provided on the end of the rotating drum 30 pointing towards the back panel 20. When the fan is running, it can transport the airflow drawn from the base to the exhaust port 22. The airflow located at the exhaust port 22 can be further transported to the rotating drum 30 through the air inlet 312, thereby achieving drying, reversing, and other treatments of the garments inside the rotating drum 30.

[0119] During the airflow from the exhaust port 22 to the inlet 312, to prevent airflow from leaking out along the gap between the back panel 20 and the rotating drum 30 and affecting the processing efficiency of the garment processing equipment 100, an axial sealing structure, namely the sealing assembly 10 mentioned above, needs to be provided between the back panel 20 and the rotating drum 30, which has the exhaust port 22 and the inlet 312. The sealing bracket 1 is arranged around the inlet 312 and the exhaust port 22 to ensure that the periphery of the inlet 312 and the exhaust port 22 is a closed space, preventing airflow leakage through the inlet 312 and the exhaust port 22.

[0120] In addition, the aforementioned sealing component 10 can also prevent lint, vapor, etc. formed inside the rotating drum 30 or carried by the airflow from leaking into the interior of the garment processing equipment 100, which helps to ensure the electrical safety inside the garment processing equipment 100 and the durability of the garment processing equipment 100.

[0121] The rotating drum 30, rotatably disposed within the housing, is configured to hold clothing to be processed. The rear end face 31 of the rotating drum 30 facing the back panel 20 has a flange 311 extending circumferentially and protruding toward the back panel 20. The rotating drum 30 can be matched with the elastic member 2 via the flange 311 protruding on the back panel 20, so that the rotating drum 30 abuts against the sealing assembly 10 via the flange 311.

[0122] When the elastic element 2 and the rotating cylinder 30 abut against each other, the surface of the elastic element 2 facing the rotating cylinder 30 is provided with a recessed abutment groove. Please refer to [link to relevant documentation]. Figure 10 The flange 311 of the rotating cylinder 30 contacts the elastic element 2 through the abutment groove.

[0123] The aforementioned abutment groove can increase the contact area between the flange 311 and the elastic element 2, which helps to enhance the sealing effect between the rotating cylinder 30 and the sealing assembly 10.

[0124] Specifically, the flange 311 can be formed by a recess in the rear end face 31 of the rotating cylinder 30 toward the back plate 20.

[0125] In some embodiments, the flange 311 is an annular structure. The annular flange 311 structure can, to some extent, avoid assembly errors and ensure that the sealing between the rotating cylinder 30 and the sealing assembly 10 remains uniform.

[0126] To reduce the assembly difficulty of the sealing bracket 1 and the back panel 20, please refer to... Figure 7 The aforementioned sealing bracket 1 has multiple positioning protrusions 4 on the side that contacts the rear panel 20. Correspondingly, the rear panel 20 has multiple positioning through holes 21 that mate with the positioning protrusions 4. Please refer to [link / reference]. Figure 11 and Figure 12 The sealing bracket 1 can be quickly assembled and positioned with the back plate 20 through the positioning protrusion 4 and positioning through hole 21. Then, the sealing bracket 1 can be firmly fixed on the back plate 20 with fasteners to achieve quick installation and fixation of the sealing bracket 1.

[0127] The garment processing device 100 with the above-mentioned sealing component 10 has better dynamic sealing performance, which helps to improve the drying effect of the garment processing device 100.

[0128] The garment processing device 100 provided in this application embodiment includes the beneficial effects of any one or more of the sealing components 10 described above, which will not be repeated here.

[0129] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0130] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
