Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a dishwasher. Background Technology

[0002] As a practical kitchen appliance, a dishwasher can automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks.

[0003] The dishwasher includes an inner tub and a door that is rotatably installed at the opening of the inner tub. A sealing strip is installed on the inner tub near the opening, and a sealing flange is provided on the door. When the door is closed, the sealing flange compresses the sealing strip to achieve a seal between the door and the inner tub, preventing water or steam from spraying out between the door and the inner tub during the dishwasher's washing process.

[0004] However, at the corner of the door liner, the sealing flange cannot fully fit tightly with the sealing strip, and steam in the inner liner can easily leak out from the corner of the door liner and the inner liner. Utility Model Content

[0005] Based on this, this application provides a dishwasher to solve the problem in the related art where steam in the inner tub easily overflows from the corner of the door lining and between the inner tub and the inner tub.

[0006] This application provides a dishwasher, including:

[0007] The inner liner has an open opening;

[0008] The first sealing strip includes an installation section and a first extension section. The installation section is connected to the inner wall of the inner liner, and the first extension section is located below the installation section and extends downward. The first extension section gradually approaches the opening from top to bottom.

[0009] The door body is rotatably mounted on the inner liner to open or close the opening. A sealing flange is provided on the door body. The sealing flange includes a first sealing section and a second sealing section that are connected to each other. The second sealing section is located on the side of the first sealing section facing the rotation axis of the door body.

[0010] The inner liner includes a chassis, and protrusions are provided on opposite sides of the chassis towards the inside of the inner liner. A first support surface is provided on the side of the protrusion facing the opening, and the first support surface abuts against the side of the first extension section away from the opening.

[0011] The distance between the first support surface and the opening is less than the distance between the side of the installation section facing away from the opening and the opening; when the door closes the opening, the first sealing section presses against the side of the installation section facing the opening, and the second sealing section presses against the side of the first extension section facing the opening.

[0012] In one possible implementation, when the door is closed, the first support surface is parallel to the side of the second sealing section facing the first extension section.

[0013] In one possible implementation, the opposite side walls of the chassis are respectively provided with slides protruding into the inner liner, with a gap between the end of the slide facing the opening and the opening, and the protrusion is located at the bottom of the slide facing the opening.

[0014] In one possible implementation, a water collection trough and a reinforcing structure are provided on the bottom surface of the chassis. The water collection trough is located in the middle of the chassis and extends downward, one end of the reinforcing structure extends to the bulge, and the other end of the reinforcing structure extends to the edge of the water collection trough.

[0015] In one possible implementation, the reinforcement structure is a stepped section formed on the chassis.

[0016] In one possible implementation, the convex hull is provided with a groove extending in a direction away from the opening, the groove is adjacent to the sidewall of the chassis, the first extension is located inside the groove, and the first support surface is the side of the groove facing the opening.

[0017] In one possible implementation, the groove has a first side surface disposed opposite to the side wall of the chassis, the end of the first side surface extending toward the opening of the groove, and the distance between the first side surface and the side wall of the chassis gradually decreasing in the direction away from the opening.

[0018] In one possible implementation, there is a first gap between the convex hull and the opening;

[0019] The first sealing strip also includes a second extension, the first end of which is connected to the bottom end of the first extension, the second end of which extends toward the opening, and the bottom surface of the second extension abuts against the bottom surface of the chassis at the first interval position.

[0020] When the door closes its opening, the end of the second sealing section away from the first sealing section presses against the top surface of the second extension section.

[0021] In one possible implementation, a second sealing strip is installed on the door.

[0022] When the door is closed, the middle part of the second sealing strip presses against the bottom surface of the chassis, and the end of the second sealing strip presses against the top surface of the second extension section.

[0023] In one possible implementation, a sealing frame is installed on the inner wall of the inner liner, and an installation groove is defined between the sealing frame and the inner wall of the inner liner.

[0024] The convex hull is located below the sealing frame;

[0025] The mounting section is embedded in the mounting groove, and the side of the mounting section away from the opening abuts against the bottom of the mounting groove.

[0026] The first extension section extends out of the mounting slot;

[0027] The distance between the first support surface and the opening is less than the distance between the bottom of the mounting groove and the opening.

[0028] The dishwasher provided in this application embodiment includes an inner tub, a first sealing strip, and a door. The first sealing strip includes an mounting section and a first extension section. A sealing flange protrudes from the door, including a first sealing section and a second sealing section connected to each other. The second sealing section is located on the side of the first sealing section facing the rotation axis of the door. The inner tub includes a chassis, with protrusions on opposite sides of the chassis facing the interior of the inner tub. A first support surface is provided on the side of the protrusion facing the opening, and the first support surface abuts against the side of the first extension section opposite to the opening. The distance between the first support surface and the opening is less than the distance between the mounting section opposite to the opening and the opening. By providing protrusions on the chassis of the inner tub, the protrusions can reduce the space between the second sealing section and the inner tub. The first support surface of the protrusion supports the second sealing section, causing the first extension section to gradually approach the opening from top to bottom. In this way, when the door is closed, the height of the second sealing section gradually decreases in the direction away from the first sealing section, which can ensure that the first extension section fits tightly with the inner liner and the door body respectively, thereby reducing the risk of steam in the inner liner overflowing from the corner of the door base and the inner liner.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0055] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0056] In existing technology, dishwashers include an inner tub and a door that is rotatably installed at the opening of the inner tub. A sealing strip is installed on the inner tub near the opening, and a sealing flange is provided on the door. When the door closes, the sealing flange compresses the sealing strip to achieve a seal between the door and the inner tub, preventing water or steam from spraying out between the door and the inner tub during the dishwasher's washing process. However, the sealing flange is generally set on the door lining using a sheet metal stretching process. Due to the limitations of the sheet metal stretching process, the height of the bottom part of the sealing flange gradually decreases. At the corner of the bottom of the door lining, where the height of the sealing flange changes, it cannot completely and tightly fit with the sealing strip. Steam in the inner tub can easily escape from the corner of the bottom of the door lining between the inner tub and the sealing strip. The overflowing steam forms condensation around the door, causing dripping water, which affects the user experience of the dishwasher and can also cause wooden cabinets to absorb water and deform.

[0057] After repeated consideration and verification, the inventors discovered that by providing a protruding portion at the bottom of the inner tub, the space between the inner tub and the bottom of the sealing flange can be reduced. This protruding portion supports the bottom of the sealing strip on the inner tub, causing the bottom of the sealing strip to gradually approach the opening of the inner tub from top to bottom. When the dishwasher door closes, the bottom of the sealing flange of the door can reliably press against the bottom of the sealing strip on the inner tub, reducing the risk of steam escaping from the corner of the door lining between the inner tub and the door itself.

[0058] In view of this, the inventors designed a dishwasher that reduces the space between the second sealing section of the sealing flange on the door and the inner tub by providing a protrusion on the base of the inner tub. The first support surface of the protrusion supports the bottom portion of the sealing strip on the inner tub, causing the bottom portion of the sealing strip to gradually approach the opening of the inner tub from top to bottom. When the door closes, the second sealing section of the sealing flange on the door compresses the bottom portion of the sealing strip. This reduces the risk of steam in the inner tub escaping between the door base and the inner tub.

[0059] The technical solution of the dishwasher provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] Reference Figures 1 to 11As shown in the embodiment of this application, the dishwasher includes an inner tub 100, a first sealing strip 200, and a door 300. The inner tub 100 has an opening 110, through which a user can place tableware into the inner tub 100 for washing.

[0061] The first sealing strip 200 includes an mounting section 210 and a first extension section 220. The mounting section 210 is connected to the inner wall of the inner liner 100. The first extension section 220 is located below the mounting section 210 and extends downwards, gradually approaching the opening 110 from top to bottom. The first sealing strip 200 is installed on the inner liner 100 near the opening 110. The first sealing strip 200 can be an extruded rubber part with a certain degree of plasticity. After being installed on the inner liner 100, it forms the mounting section 210 and the first extension section 220. The mounting section 210 has an approximate "U" shape, with the opening of the "U" shape facing downwards. The bottom edge of the "U" shape is connected to the inner top wall of the inner liner 100, and the two sides of the "U" shape are respectively connected to the two opposite inner sidewalls of the inner liner 100. There are two first extension sections 220, each connected to one end of the mounting section 210. The mounting section 210 and the two first extension sections 220 can be integrally formed into a single piece. For example, the first extension segment 220 extends gradually forward from top to bottom.

[0062] The door body 300 is rotatably mounted on the inner liner 100 to open or close the opening 110. Schematic, a support assembly 150 can be riveted to the opening 110 of the inner liner 100. Fixing plates are provided on both sides of the bottom of the support assembly 150, and pivots can be mounted on the fixing plates. The door body 300 includes components such as a door liner 301, a hinge 330, a display panel box, a left support, a right support, a distributor, and a latch. The hinge 330 has fixing holes that can connect to the pivots on the fixing plates, allowing the door body 300 to rotate 0°-90° around the axis of the pivot to open or close the opening 110. When the door body 300 closes the opening 110, the door liner 301 of the door body 300 faces inwards towards the inner liner 100.

[0063] A sealing flange 310 protrudes from the door body 300. The sealing flange 310 includes a first sealing section 311 and a second sealing section 312 connected to each other. The second sealing section 312 is located on the side of the first sealing section 311 facing the rotation axis of the door body 300. The sealing flange 310 can be formed by stretching and shaping onto the door liner 301 of the door body 300. The first sealing section 311 is also approximately U-shaped, with its opening facing the rotation axis of the door body 300. The sealing flange 310 can cooperate with the first sealing strip 200 to achieve a seal between the inner liner 100 and the door body 300. There are two second sealing sections 312, located at opposite ends of the first sealing section 311. Notably, to facilitate the stretching and shaping of the sealing flange 310, the height of the second sealing section 312 gradually decreases from the first sealing section 311 towards the rotation axis of the door body 300, and the end of the second sealing section 312 away from the first sealing section 311 has a smooth transition.

[0064] The inner liner 100 includes a chassis 120, and protrusions 121 are respectively provided on opposite sides of the chassis 120 protruding into the inner liner 100. For example... Figure 6 and Figure 7 As shown, the inner liner 100 also includes a top plate 130 and a U-shaped plate 140. The top of the U-shaped plate 140 can be fixed to the top plate 130 by interlocking, and the bottom of the U-shaped plate 140 can be fixed to the chassis 120 by interlocking. For example, protrusions 121 can be formed on opposite sides of the chassis 120 by stretch forming. The protrusions 121 are arranged near the opening 110 of the inner liner 100.

[0065] A first support surface 1211 is provided on the side of the convex bulge 121 facing the opening 110, and the first support surface 1211 abuts against the side of the first extension 220 opposite to the opening 110. The side of the first extension 220 away from the opening 110 is the second mounting base surface 221, and the first support surface 1211 abuts against the second mounting base surface 221. (Illustrative example, as shown...) Figure 8 and Figure 9 As shown, the convex bulge 121 also includes an upper surface 1215 and a second support surface 1214. The upper surface 1215 is located at the top of the convex bulge 121, and the second support surface 1214 is located on the side of the convex bulge 121 away from the side wall of the inner liner 100. The upper surface 1215 and the first support surface 1211 are transitioned by a first transition surface 1216, the first support surface 1211 and the second support surface 1214 are transitioned by a third transition surface 1218, and the upper surface 1215 and the second support surface 1214 are transitioned by a second transition surface 1217.

[0066] The distance between the first support surface 1211 and the opening 110 is less than the distance between the side of the mounting section 210 facing away from the opening 110 and the opening 110. That is, the first support surface 1211 is closer to the opening 110 than the side of the mounting section 210 facing away from the opening 110. Those skilled in the art will understand that the convex bulge 121 reduces the space between the bottom portion of the inner liner 100 and the door body 300. This embodiment does not limit the specific size of the distance between the first support surface 1211 and the opening 110; those skilled in the art can set it as needed.

[0067] When the door 300 closes the opening 110, the first sealing section 311 presses against the side of the mounting section 210 facing the opening 110, and the second sealing section 312 presses against the side of the first extension section 220 facing the opening 110. The first sealing section 311 has a first contact surface, and the second sealing section 312 has a second contact surface. When the door 300 closes the opening 110, both the first and second contact surfaces face the interior of the inner liner 100. Here, the surface of the first sealing strip 200 that mates with the door 300 is defined as the sealing surface 240. When the door 300 closes the opening 110, the first contact surface adheres to the sealing surface 240 at the position of the mounting section 210, and the second contact surface adheres to the sealing surface 240 at the position of the first extension section 220. It is worth noting that the first sealing strip 200 has a certain degree of elasticity; it can undergo elastic deformation when subjected to external force, sealing the gap between the inner liner 100 and the door 300 through the elastic deformation of the first sealing strip 200.

[0068] The dishwasher provided in this embodiment reduces the space between the second sealing section 312 and the inner tub 100 by providing a protrusion 121 on the chassis 120 of the inner tub 100. The first support surface 1211 of the protrusion 121 supports the second sealing section 312, causing the first extension section 220 to gradually approach the opening 110 from top to bottom. In this way, when the door 300 closes the opening 110, the height of the second sealing section 312 gradually decreases in the direction away from the first sealing section 311, ensuring that the first extension section 220 fits tightly with both the inner tub 100 and the door 300, thereby reducing the risk of steam in the inner tub 100 escaping from the corner at the bottom of the door liner 301 between the inner tub 100 and the door 300.

[0069] In one embodiment, when the door 300 closes the opening 110, the first support surface 1211 is parallel to the side of the second sealing section 312 facing the first extension section 220.

[0070] Specifically, when the door 300 closes the opening 110, the distance between the first support surface 1211 and the second contact surface is equal everywhere. Understandably, when the door 300 closes the opening 110, the deformation of the first extension section 220 is relatively uniform, and the compression of the first sealing strip 200 is controllable, which helps ensure the reliability of the seal between the bottom corner of the door liner 301 and the inner liner 100.

[0071] In other embodiments, the first support surface 1211 and the side of the second sealing section 312 facing the first extension section 220 are nearly parallel, for example, the angle between the first support surface 1211 and the side of the second sealing section 312 facing the first extension section 220 does not exceed 5°.

[0072] In one embodiment, such as Figure 1 and Figures 5-9 As shown, the opposite side walls of the chassis 120 are respectively provided with slides 122 protruding into the inner liner 100. There is a gap between the end of the slide 122 facing the opening 110 and the opening 110, and the protrusion 121 is located at the bottom of the side of the slide 122 facing the opening 110.

[0073] Schematic illustration: the slide rails 122 can be extended to opposite sides of the chassis 120. Those skilled in the art will understand that each slide rail 122 extends in the front-to-back direction, facilitating the pulling of the dishwasher's lower shelf relative to the inner tub 100. For example... Figure 9 As shown, the convex bulge 121 is located in the gap between the slide 122 and the opening 110. One side of the first support surface 1211 of the convex bulge 121 overlaps the side wall of the inner liner 100 and forms a certain angle with the extension direction of the slide 122. One side of the upper surface 1215 overlaps the side wall of the inner liner 100 and the other side overlaps the area below the slide 122.

[0074] In this embodiment, the convex 121 is located on the front side of the slide 122. After the door body 300 closes the opening 110, the convex 121 can reliably reduce the space between the inner liner 100 and the second sealing section 312 in the front-back direction, so that the first extension section 220 at the bottom of the first sealing strip 200 is reliably compressed, ensuring the reliability of the seal between the corner at the bottom of the door liner 301 and the inner liner 100.

[0075] In one embodiment, such as Figure 12 and Figure 13 As shown, a water collection trough 123 and a reinforcing structure 124 are provided on the bottom surface of the chassis 120. The water collection trough 123 is located in the middle of the chassis 120 and extends downward. One end of the reinforcing structure 124 extends to the protrusion 121, and the other end of the reinforcing structure 124 extends to the edge of the water collection trough 123.

[0076] The water collection tank 123 can be installed in the middle of the chassis 120 by stretching. The cross-section of the water collection tank 123 can be square or circular or other suitable shapes. The depth of the water collection tank 123 can be set as needed. It can be understood that the water collection tank 123 is at the lowest point of the chassis 120. During the dishwasher washing process, the washing liquid can flow back to the water collection tank 123 for reuse. Figure 12 and Figure 13 As shown, the reinforcing structure 124 extends from the chassis 120 near the corner to the water collection tank 123.

[0077] Those skilled in the art will understand that the reinforcing structure 124 makes the sidewalls, slides 122, protrusions 121, and water collection tank 123 of the chassis 120 form a connected whole, thereby strengthening the structural strength of the chassis 120. The lower spray arm of the dishwasher is rotatably connected to the chassis 120 of the inner tub 100. The high structural strength of the chassis 120 can increase the stability of the lower spray arm during washing, which is beneficial to improving the washing effect of the dishwasher.

[0078] In one specific implementation, such as Figure 12 and Figure 13 As shown, the reinforcing structure 124 is a stepped section formed on the chassis 120.

[0079] The stepped portion can be formed on the chassis 120 by stretching. The height of the stepped portion can be set as needed and is not limited here.

[0080] In this embodiment, the stepped portion can be easily set on the chassis 120. In addition, the stepped portion extends from the edge of the chassis 120 to the water collection tank 123, which can facilitate the rapid return of the washing liquid during the washing process. This improves the utilization efficiency of the washing liquid, enhances the washing effect, or reduces the overall amount of washing liquid used.

[0081] In other embodiments, the reinforcing structure 124 can be a reinforcing rib protruding from the chassis 120 toward the inner liner 100, thereby strengthening the structural strength of the chassis 120.

[0082] In one embodiment, such as Figure 1 and Figures 14-17 As shown, the convex bulge 121 is provided with a groove 1212 extending in a direction away from the opening 110. The groove 1212 is adjacent to the side wall of the chassis 120. The first extension section 220 is located inside the groove 1212. The first support surface 1211 is the side of the groove 1212 facing the opening 110.

[0083] The opening of the groove 1212 faces the opening 110, and the width of the groove 1212 is not less than the width of the first extension 220. During the assembly process, the first extension 220 can extend from the opening of the groove 1212 into the bottom of the groove 1212.

[0084] In this embodiment, the groove 1212 of the protrusion 121 can accommodate the first extension 220 of the first sealing strip 200. The first extension 220 can be limited by the side wall of the chassis 120 and the side wall of the groove 1212 opposite to the chassis 120, thereby restricting the lateral movement of the first extension 220 relative to the inner liner 100, ensuring that the first extension 220 can reliably abut against the second sealing section 312 of the sealing flange 310 on the door body 300, and ensuring the sealing effect between the corner of the bottom of the door liner 301 and the inner liner 100.

[0085] In one possible implementation, the recess 1212 has a first side surface 1213. The first side surface 1213 is disposed opposite to the side wall of the chassis 120, and one end of the first side surface 1213 extending toward the opening 110 extends to the opening of the recess 1212. The distance between the first side surface 1213 and the side wall of the chassis 120 gradually decreases in the direction away from the opening 110.

[0086] Understandably, when the first extension 220 of the first sealing strip 200 is placed in the groove 1212, the first side 1213 of the groove 1212 and the side wall of the chassis 120 can limit the first extension 220. Understandably, the width of the groove 1212 gradually decreases in the direction away from the opening 110.

[0087] With the above configuration, the first side 1213 of the groove 1212 can guide the first extension 220 of the first sealing strip 200, making it easier for workers to put the first extension 220 into the groove 1212, which helps to improve the assembly efficiency of the dishwasher.

[0088] In one embodiment, such as Figure 1 , Figures 5-7 , Figure 10 and Figure 11 As shown, there is a first gap between the convex bulge 121 and the opening 110. The first sealing strip 200 also includes a second extension 230, the first end of which is connected to the bottom end of the first extension 220, and the second end of which extends toward the opening 110. The bottom surface of the second extension 230 abuts against the bottom surface of the chassis 120 at the first gap position. The bottom surface of the second extension 230 is a third mounting surface 231, which abuts against the bottom surface of the chassis 120. When the door 300 closes the opening 110, the end of the second sealing section 312 away from the first sealing section 311 presses against the top surface of the second extension 230.

[0089] The first interval provides installation space for the second extension segment 230. Each of the two first extension segments 220 is connected to a second extension segment 230 at its end furthest from the mounting segment 210. The mounting segment 210, the first extension segments 220, and the second extension segments 230 can be formed into a single piece using an integral molding process. The second extension segment 230 can extend in the front-rear direction, with its front end facing the opening 110 and its rear end connected to the bottom end of the first extension segment 220.

[0090] Here, the end of the second sealing section 312 furthest from the first sealing section 311 is defined as the lower edge 313 of the second sealing section 312. During the process of closing the opening 110 of the door body 300, the lower edge 313 of the second sealing section 312 gradually presses downward against the second extension section 230. When the door body 300 closes the opening 110, the second extension section 230 is located between the lower edge 313 of the second sealing section 312 and the bottom wall of the chassis 120.

[0091] This structure further improves the sealing effect between the bottom corner of the door liner 301 and the inner liner 100 by pressing the top surface of the second extension section 230 with the end of the second sealing section 312 away from the first sealing section 311.

[0092] like Figure 1 , Figure 3 , Figure 4 and Figure 10 As shown, a second sealing strip 320 is installed on the door body 300. The second sealing strip 320 is located on the side of the sealing flange 310 facing the rotation axis of the door body 300. Schematic, both ends of the second sealing strip 320 may extend beyond the sealing flange 310.

[0093] When the door 300 closes the opening 110, the middle of the second sealing strip 320 presses against the bottom surface of the chassis 120, and the end of the second sealing strip 320 presses against the top surface of the second extension 230. It is worth noting that after the door 300 closes the opening 110, the first sealing strip 200 and the second sealing strip 320 define an annular structure, which surrounds the inner wall of the inner liner 100. The first sealing strip 200 and the second sealing strip 320 together seal the gap between the door 300 and the inner liner 100. During the process of closing the opening 110, the end of the second sealing strip 320 gradually presses against the first sealing strip 200 from top to bottom.

[0094] The cooperation between the second sealing strip 320 and the first sealing strip 200 further improves the sealing effect between the corner at the bottom of the door liner 301 and the inner liner 100.

[0095] In one specific implementation, such as Figures 4-7 and Figure 12As shown, a sealing frame 160 is installed on the inner wall of the inner liner 100, and a mounting groove 170 is defined between the sealing frame 160 and the inner wall of the inner liner 100. A protrusion 121 is located below the sealing frame 160. A mounting section 210 is embedded in the mounting groove 170, and the side of the mounting section 210 facing away from the opening 110 abuts against the bottom of the mounting groove 170. The sealing frame 160 can be fixed to the inner liner 100 by riveting. Schematably, the sealing frame 160 includes a first limiting wall and a second limiting wall, which, together with the side wall of the inner liner 100, define the mounting groove 170. The cross-sectional shape of the mounting groove 170 can be U-shaped, with the opening of the U-shape facing the opening 110, allowing a portion of the mounting section 210 to be inserted into the mounting groove 170 through the opening. The sidewall of the mounting groove 170 can exert a compressive force on the portion of the mounting section 210 located in the mounting groove 170, preventing the portion of the mounting section 210 from coming out of the mounting groove 170. The side of the mounting section 210 away from the opening 110 is the first mounting bottom surface 211. The bottom wall of the mounting groove 170 can abut against the first mounting bottom surface 211 to restrict the movement of the mounting section 210 away from the opening 110, ensuring that the mounting section 210 can reliably cooperate with the first sealing section 311 to seal the gap between the inner liner 100 and the door body 300.

[0096] The first extension section 220 extends out of the mounting groove 170. The distance between the first support surface 1211 and the opening 110 is less than the distance between the bottom of the mounting groove 170 and the opening 110. Slides 122 protrude from opposite sides of the chassis 120 toward the interior of the inner liner 100. Restricted by the slides 122, the bottom wall of the mounting groove 170 cannot extend below the slides 122. After the first extension section 220 extends out of the mounting groove 170, the first support surface 1211 of the protrusion 121 can restrict the first extension section 220 from moving away from the opening 110. That is, the first support surface 1211 can extend the bottom wall of the mounting groove 170. The distance between the first support surface 1211 and the opening 110 being less than the distance between the bottom of the mounting groove 170 and the opening 110 ensures that the protrusion 121 of the chassis 120 can reliably reduce the space between the second sealing section 312 and the inner liner 100. In this embodiment, there are no restrictions on the specific size of the distance between the first support surface 1211 and the opening 110, or the distance between the bottom of the mounting groove 170 and the opening 110. Those skilled in the art can set these dimensions according to actual needs.

[0097] The above-mentioned arrangement can reliably fix the mounting section 210 of the first sealing strip 200 to the inner liner 100, and ensure that the protrusion 121 can reliably reduce the space between the bottom corner of the door liner 301 and the inner liner 100, and ensure that the second sealing section 312 of the sealing flange 310 on the door body 300 can reliably press the first extension section 220 of the first sealing strip 200, so as to ensure the sealing effect between the bottom corner of the door liner 301 and the inner liner 100.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
