Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a cabinet assembly and a freezer. Background Art

[0002] A freezer is a refrigerator that stores food or other items by keeping them in a constant, cold state. Typically, a freezer includes a cabinet body and a door. The cabinet body has a storage space and a cabinet opening connected to the storage space. The door is mounted on the cabinet opening and can be opened and closed reciprocally relative to the cabinet opening, thereby opening or closing the storage space of the cabinet body.

[0003] In the related art, a seal (such as a door seal) is typically installed between the door and the opening of a freezer. This seal seals the gap between the door and the opening by squeezing the door and the opening against it, thereby reducing cold leakage from the freezer. However, during use, the door seal typically moves with the door, and the frequent opening and closing of the door relative to the opening exerts a significant closing force on the opening, which can easily damage the freezer and compromise its sealing, affecting its insulation performance. Utility Model Content

[0004] In view of this, the present application provides a cabinet assembly and a freezer, which can have both a buffering effect and a sealing effect, so as to improve the sealing performance of the connection between the cabinet door and the cabinet body and improve the heat preservation effect of the freezer.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0006] According to a first aspect of an embodiment of the present disclosure, a cabinet assembly is provided, comprising a cabinet and a sealing member. The cabinet comprises a housing cavity and a cabinet opening communicating with the housing cavity. The sealing member comprises a sealing groove for sealingly engaging with a cabinet door and an airbag disposed within the sealing groove. The outer wall of the sealing groove is connected to the inner wall of the cabinet opening, and the airbag protrudes from the bottom wall of the sealing groove along the depth direction of the sealing groove.

[0007] The cabinet assembly provided by this application has the following beneficial effects:

[0008] When the cabinet assembly provided by the present application is in use, the sealing groove can be used to cooperate with the cabinet door that moves back and forth relative to the cabinet. The depth direction of the sealing groove is set along the direction in which the cabinet door is inserted into the sealing groove. Among them, the airbag is set on the bottom wall of the sealing groove, so that in the process of inserting the cabinet door into the sealing groove, the cabinet door can be squeezed with the airbag, causing the airbag to undergo elastic deformation, and the side wall of the cabinet door opposite to the bottom wall of the sealing groove is fitted and sealed with the airbag to reduce the plug-in gap between the cabinet door and the sealing groove, forming a sealed fit. At the same time, the elastic deformation of the airbag can also play a buffering role, absorbing the impact force of the cabinet door on the cabinet along the direction of movement of the cabinet door, and forming a flexible closure between the cabinet door and the cabinet. This can not only reduce the noise of closing the door, but also prevent the cabinet door, cabinet or seal from being damaged by impact. Therefore, the cabinet assembly provided by the present application has both buffering and sealing effects.

[0009] According to a second aspect of an embodiment of the present disclosure, a refrigerator is provided, comprising a cabinet door and the cabinet body assembly described above. The cabinet door is configured to reciprocate relative to the cabinet body to open and close a storage cavity. When the cabinet door closes the storage cavity, it inserts into a sealing groove and compresses an airbag, whereupon the cabinet door seals against the cabinet body via a sealing member. When the cabinet door opens the storage cavity, the cabinet door separates from the airbag and moves out of the sealing groove.

[0010] The freezer provided by this application has the following beneficial effects:

[0011] When the freezer door is closed, the door gradually enters the sealing groove and squeezes the airbag, causing the airbag to elastically deform and seal against the door. This arrangement not only improves the sealing effect between the door and the cabinet opening, but also uses the airbag to absorb the impact of the door closing, preventing damage to the freezer and reducing cold leakage.

[0012] In addition, it should be noted that the cabinet assembly provided in this application is not limited to use in freezers. The cabinet assembly provided in this application can also be applied to other furniture, home appliances or equipment, such as wardrobes, storage cabinets or other equipment housings, etc., and this application does not impose any restrictions.

[0027] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships, movement, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of the present application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0029] With the development of society and the improvement of people's living standards, refrigeration equipment (such as refrigerators and freezers) has become an indispensable household appliance in people's daily lives. However, with a wide variety of types and brands of refrigeration equipment, consumers are overwhelmed with choices. How to win consumer favor and improve product competitiveness has become an increasingly important issue for refrigeration equipment manufacturers.

[0030] Freezers, as refrigeration equipment, have doors that allow light to pass through, making it easier for people to see the items stored inside. They are widely used in commercial settings such as supermarkets, convenience stores, and shopping malls. Typically, a freezer consists of a cabinet body and a door. The cabinet body has a storage space and an opening that connects to the storage space. The door is mounted on the opening and reciprocates relative to the opening, thereby opening and closing the cabinet storage space.

[0031] In the related art, a seal (such as a door seal) is typically installed between the door and the opening of a freezer. This seal seals the gap between the door and the opening 113 by squeezing the door and the opening against the seal, thereby reducing cold leakage from the freezer. However, the door seals in the related art are typically mounted on the door and move with the door as it opens and closes. Furthermore, the door frequently opens and closes relative to the opening 113, exerting a significant closing force on the opening 113. This can easily damage the door, cabinet, or seal, leading to poor sealing and frosting in the freezer, impacting the user experience.

[0032] Therefore, the present application provides a freezer 10, which can buffer the closing impact of the cabinet door 120 on the cabinet body 110, and prevent the seal 130 between the cabinet door 120 and the cabinet body 110 from falling off, and further improve the sealing effect between the cabinet door 120 and the cabinet body 110, thereby improving the heat preservation effect of the freezer 10, avoiding frosting in the freezer 10, and improving the user experience.

[0033] The freezer 10 provided in this application will be described below with reference to the accompanying drawings.

[0034] See also Figures 1 to 3The present application provides a refrigerator 10, comprising a cabinet assembly 100 and a cabinet door 120. The cabinet assembly 100 comprises a cabinet 110 and a sealing member 130. The cabinet 110 has a receiving cavity 111 and a cabinet opening 113 communicating with the receiving cavity 111. The sealing member 130 is fixed to the inner side wall of the cabinet opening 113. The cabinet door 120 is disposed at the cabinet opening 113 and is configured to reciprocate relative to the cabinet 110 to open or close the receiving cavity 111. When the cabinet door 120 closes the receiving cavity 111, the cabinet door 120 and the sealing member 130 are squeezed to form a sealed fit.

[0035] It should be noted that the cabinet body 110 of the freezer 10 can be made by enclosing and splicing a plurality of side panels. The accommodating cavity 111 of the cabinet body 110 can be used to form a refrigerator or freezer for users to store items. The opening of the accommodating cavity 111 of the freezer 10 can be opened along the Y direction in the figure, and the depth direction of the accommodating cavity 111 is correspondingly set in the opposite direction of Y. The cabinet door 120 can be connected to the cabinet opening 113 of the cabinet body 110 by sliding or rotating, so that the user can move the cabinet door 120 by sliding, pushing, or rotating to open and close the accommodating cavity 111 of the freezer 10 and store and retrieve items.

[0036] Taking the sliding connection between the cabinet door 120 and the cabinet body 110 as an example, the seal 130 can be arranged on the inner side wall extending along the depth direction of the accommodating cavity 111. When the cabinet door 120 slides closed relative to the cabinet body 110, the side wall of the cabinet door 120 can be squeezed with the seal 130 on the side wall of the cabinet body 110 to form a sealed fit, thereby sealing the closed gap between the cabinet door 120 and the cabinet opening 113, preventing cold air from leaking out of the accommodating cavity 111 of the freezer 10, and achieving heat preservation of the freezer 10.

[0037] In this way, during the reciprocating movement of the cabinet door 120 relative to the cabinet body 110, the seal 130 is always fixed to the inner wall of the cabinet door 120 and does not move with the cabinet door 120, thereby avoiding frequent movement of the seal 130 and reducing the risk of the seal 130 falling off, so that the seal 130 can be firmly installed on the inner side of the cabinet body 110, and then an effective closed seal can be formed between the cabinet door 120 and the cabinet body 110, reducing the cold leakage of the freezer 10, and avoiding frost on the freezer 10, thereby improving the user's use effect.

[0038] See also Figure 3 and Figure 4In some embodiments, in order to further cushion the closing impact of the cabinet door 120 on the cabinet body 110 and improve the connection stability between the cabinet door 120 and the cabinet body 110, the present application also provides a cabinet assembly 100. The cabinet assembly 100 includes a cabinet body 110 and a seal 130. The cabinet body 110 is provided with a accommodating cavity 111 and a cabinet opening 113 connected to the accommodating cavity 111. The seal 130 is provided with a sealing groove 150 for sealing with the cabinet door 120, and the outer wall of the sealing groove 150 is connected to the inner wall of the cabinet opening 113. The seal 130 includes an airbag arranged in the sealing groove 150. In the depth direction of the sealing groove 150, the airbag 160 protrudes from the bottom wall of the sealing groove 150.

[0039] It should be noted that the sealing member 130 can be configured in any shape, such as a strip or block, and this application does not impose any limitation. For example, with the thickness of the sealing member 130 oriented in the X-direction as shown in the figure, a portion of the sidewall of the sealing member 130 can be recessed in the X-direction to form a sealing groove 150. The depth of the sealing groove 150 is oriented in the X-direction, and the cabinet door 120 is inserted into the sealing groove 150 along the depth direction of the sealing groove 150.

[0040] The outer wall of the sealing groove 150 is used to form a connecting side 133 for mounting the sealing member 130 on the cabinet body 110. The inner wall of the sealing groove 150 is used to form a sealing side 132 for plugging and sealing with the cabinet door 120. To facilitate the formation of the sealing groove 150, the sealing member 130 may be elastic, and the connecting side 133 of the sealing member 130 may be bent toward the sealing side 132 to form the sealing groove 150. At the same time, the outer wall of the sealing groove 150 may also form a bent surface at the connecting side 133, and a mounting groove 114 may be provided on the inner side wall of the cabinet body 110, and the sealing member 130 may be entirely embedded in the mounting groove 114 of the cabinet body 110 to improve the sealing effect between the sealing member 130 and the cabinet opening 113. At the same time, in the depth direction of the accommodating cavity 111, the lower side wall of the mounting groove 114 can be used as a bearing surface 114b for supporting the seal 130, and the upper side wall of the mounting groove 114 can be used as a limiting surface 114a for the installation of the seal 130. In this way, when the cabinet door 120 is inserted into the sealing groove 150, a sealing fit is formed between the cabinet door 120 and the cabinet body 110 through the seal 130 to close the accommodating cavity 111. In addition, the seal 130 can also be fixed in the mounting groove 114 by gluing. This double fit of adhesive fixation and interlocking installation can further improve the sealing effect and connection reliability of the seal 130 and the cabinet body 110. The sealing groove 150 can be set as an L-shaped groove or a U-shaped groove, etc., and this application does not impose any restrictions. In addition, the mounting groove 114 can also be used to hide and protect the seal 130 to prevent the seal 130 from being damaged by foreign objects or falling off due to impact.

[0041] The airbag 160 is elastic and can be squeezed by the cabinet door 120 to produce elastic deformation, thereby sealing the insertion gap between the cabinet door 120 and the sealing groove 150. At the same time, the elastic deformation of the airbag 160 can also buffer the impact force of the cabinet door 120 on the cabinet body 110 when entering the sealing groove 150. Specifically, during the insertion process of the cabinet door 120 and the sealing groove 150, the cabinet door 120 enters the sealing groove along the X direction, and the airbag 160 is arranged on the bottom wall of the sealing groove and protrudes from the bottom wall along the opposite direction of X. With this arrangement, the airbag 160 can be used to form a gap between the cabinet door 120 and the cabinet body 110, preventing the cabinet door 120 from directly impacting the seal 130 or the cabinet body 110 along the X direction, thereby buffering the impact force of the cabinet door 120 and preventing damage to the refrigerator components such as the cabinet door 120, the seal 130 or the cabinet body 110. At the same time, during the closing process of the cabinet door 120, the side walls of the cabinet door 120 set along the Y direction are squeezed by the airbag 160, and the airbag 160 undergoes elastic deformation to fit tightly with the side walls of the cabinet door 120, so that the cabinet door 120 forms a sealed fit with the sealing groove 115.

[0042] In other embodiments, the airbag 160 may also be disposed on other side inner walls of the sealing groove 150 , or may cover all inner walls of the sealing groove 150 , which is not limited in this application.

[0043] Therefore, the seal 130 provided in this application can not only use the airbag 160 to buffer the impact force of the cabinet door 120 on the cabinet body 110, but also squeeze the airbag 160 and the cabinet door 120 to form a sealed fit to seal the plug-in gap between the cabinet door 120 and the sealing groove 150, thereby improving the sealing effect between the cabinet door 120 and the cabinet body 110.

[0044] See also Figure 3 and Figure 4 In some embodiments, to enhance the cushioning effect of the cabinet assembly 100, the airbag 160 includes a deformable portion 161 in an arcuate shape. The two ends of the deformable portion 161 are connected to the inner wall of the sealing groove 150. The curved portion of the deformable portion 161 protrudes toward the opening of the sealing groove 150 to form a bladder cavity 162 in cooperation with the inner wall of the sealing groove 150.

[0045] In this way, the arc-shaped deformation portion 161 can cooperate with the inner wall of the sealing groove 150 to form a cavity 162, and the cavity 162 further increases the elastic deformation range of the airbag 160 to improve the absorption effect of the impact force of the cabinet door 120. In addition, the cavity 162 is filled with gas, and the impact noise of the cabinet door 120 can also be absorbed by the cavity 162. For example, when the cabinet door 120 is closed relative to the cabinet body 110, the cavity 162 of the airbag 160 can absorb the impact force of the cabinet door 120 closing, thereby preventing the seal 130 from falling off, and the cavity 162 can also absorb the noise of the cabinet door 120 closing to achieve silent closing. Among them, the deformation portion 161 can be set to a circular arc or semicircular shape, etc., which is not limited in this application.

[0046] See also Figure 4 In some embodiments, to further enhance the cushioning effect of the deformable portion 161, the elastic force of the deformable portion 161 gradually decreases along the protruding direction of the deformable portion 161. Thus, when the cabinet door 120 is inserted into the sealing groove 150, it first comes into contact with the portion of the deformable portion 161 with greater elastic force. This absorbs part of the impact force of the cabinet door 120 through greater elastic deformation, allowing the cabinet door 120 to be partially embedded in the wrapping of the deformable portion 161, preventing the cabinet door 120 from bouncing back out of the sealing groove 150 and creating a gap. The portion of the deformable portion 161 with less elastic force then acts to brake the cabinet door 120, preventing the cabinet door 120 from continuing to impact the inner wall of the sealing groove 150 and damaging or causing the seal 130 to fall off due to the impact.

[0047] See also Figure 4 In some embodiments, to prevent the deformation portion 161 from failing, the airbag 160 further includes a support portion 163 , which is disposed in the airbag cavity 162 and connected between the inner wall of the sealing groove 150 and the deformation portion 161 .

[0048] It should be noted that when the deformable portion 161 is squeezed, the support portion 163 can elastically deform along with the deformable portion 161 to jointly absorb the impact force of the cabinet door 120, thereby preventing the deformable portion 161 from failing. In addition, the support portion 163 supports the deformable portion 161 within the cavity 162 and assists the deformable portion 161 in restoring its elastic deformation when the cabinet door 120 moves out of the sealing groove 150, thereby absorbing the impact force the next time the cabinet door 120 enters the sealing groove 150. The support portion 163 can be configured in any shape, such as a straight line, an arc, or a wave, and this application does not impose any restrictions.

[0049] See also Figure 4In some embodiments, the seal 130 may also be elastic and adapted to form a squeeze seal with the cabinet door 120. To prevent the airbag 160 from excessively squeezing the sealing groove 150 during deformation, causing the sealing groove 150 to deform and fail to form a seal with the cabinet door 120, the airbag 160 may be positioned on one sidewall of the sealing groove 150 and spaced apart from the other sidewalls.

[0050] As an example, seal 130 includes a first sealing portion 134 and a second sealing portion 135 connected to first sealing portion 134. First sealing portion 134 and second sealing portion 135 extend along the length of seal 130 and cooperate to form sealing groove 150. Airbag 160 is connected to first sealing portion 134 and spaced apart from second sealing portion 135. This creates a gap between airbag 160 and second sealing portion 135, allowing for deformation during airbag 160's deformation process. This prevents compression and deformation of sealing groove 150, which could create a gap between sealing groove 150 and cabinet door 120 and affect the sealing effect.

[0051] See also Figures 4 to 6 In some embodiments, in order to further improve the sealing effect of the cabinet assembly 100, the cabinet assembly 100 further includes a sealing fin, which is connected to the inner wall of the sealing groove and one of the airbags.

[0052] As an example, the sealing fin includes a first fin 170, the root of which is connected to the airbag 160. With this arrangement, when the cabinet door enters the sealing groove, the door and the airbag are squeezed, and the elastic deformation of the airbag can form a seal with the side wall of the cabinet door. Simultaneously, the elastic deformation of the airbag 160 can drive the first fin 170 into the interior of the sealing groove 150, thereby narrowing the opening of the sealing groove 150 and causing the first fin 170 to press against the lower surface of the cabinet door 120, forming a seal. This creates a double seal between the cabinet door and the sealing groove, enhancing the sealing effect of the seal 130.

[0053] Of course, the sealing fins may not be connected to the airbag, but may be arranged on the inner wall of the sealing groove separately from the airbag. When the cabinet door is inserted into the sealing groove, the cabinet door, the airbag and the sealing fins are squeezed to form a double seal, which is not elaborated in this application.

[0054] In some embodiments, to further improve the sealing effect, as an example, two sealing fins are provided, namely a first fin 170 and a second fin 180. The airbag 160 is provided in the first sealing portion 134, and the first fin 170 is connected to the airbag 160. The second fin 180 is connected to the second sealing portion 135, and the first fin 170 and the second fin 180 are staggered with each other. For example, the first fin 170 and the second fin 180 are staggered along the X direction. In this way, when the cabinet door 120 is inserted into the sealing groove 150 along the X direction, the cabinet door 120 first touches the top second fin 180, causing the second fin 180 to move to fit between the sealing groove 150 and the upper surface of the cabinet door 120, forming a seal. As the cabinet door 120 continues to be inserted into the sealing groove 150, the cabinet door 120 squeezes the airbag 160, causing the airbag 160 to deform, thereby driving the first fin 170 to move into the sealing groove 150, forming a double-layer seal between the lower surface of the cabinet door 120 and the sealing groove 150, thereby improving the sealing effect between the cabinet door 120 and the sealing groove 150. At the same time, the deformation of the airbag 160 can also cause the airbag 160 to be tightly pressed against the side wall of the cabinet door 120, forming a three-layer seal. It is understandable that the upper and lower surfaces of the cabinet door 120 can be arranged with relative spacing along the Y direction in the figure, and the side wall of the cabinet door 120 can be arranged facing the airbag 160 along the X direction.

[0055] Furthermore, to facilitate the insertion and exit of the cabinet door 120 into and out of the sealing groove 150, the first fin 170 and the second fin 180 can be tilted in different directions. Specifically, the top of the first fin 170 can be tilted toward the outside of the sealing groove 150 relative to the root of the first fin 170, while the top of the second fin 180 can be tilted toward the inside of the sealing groove 150 relative to the root of the second fin 180. For example, the tilt direction of the first fin 170 from the root to the top can be set at an obtuse angle of no more than 180 degrees with the direction in which the cabinet door 120 is inserted into the sealing groove 150 (e.g., the X-direction). The tilt direction of the second fin 180 from the root to the top can be set at an acute angle with the direction in which the cabinet door 120 is inserted into the sealing groove 150 (e.g., the X-direction).

[0056] Thus, during the insertion of the cabinet door 120 into the sealing groove 150, the second fin 180 can move clockwise to approach the inner wall of the sealing groove 150, thereby reducing the friction between the cabinet door 120 and the cabinet door 120, allowing the cabinet door 120 to continue to be inserted into the sealing groove 150, thereby driving the first fin 170 to move by squeezing the airbag 160. At the same time, the first fin 170 extends outward from the sealing groove 150 to avoid blocking the opening of the sealing groove 150, allowing the cabinet door 120 to enter the sealing groove 150 smoothly.

[0057] During the process of the cabinet door 120 moving out of the sealing groove 150, the cabinet door 120 separates from the airbag 160, allowing the airbag 160 to recover its deformation, thereby driving the first fin 170 to recover its deformation and open the opening of the sealing groove 150, providing space for the cabinet door 120 to move out. At the same time, the removal space provided by the first fin 170 can also be used to prevent the second fin 180 from moving counterclockwise and interfering with the cabinet door 120 when the cabinet door 120 moves relative to the second fin 180, thereby allowing the cabinet door 120 to move out of the sealing groove 150 smoothly. In addition, by avoiding the movement interference caused by the cabinet door 120 moving out of the sealing groove 150, it is also possible to prevent the cabinet door 120 from driving the seal 130 away when moving out of the sealing groove 150, thereby preventing the seal 130 from falling off during the movement of the cabinet door 120.

[0058] See 4 to Figure 6 In some embodiments, in order to improve the connection stability between the seal 130 and the cabinet door 120, the inner wall of the cabinet body 110 is provided with a plug-in portion 112, and the outer wall of the sealing groove 150 is provided with a plug-in fitting portion 131. Through the plug-in fitting of the plug-in portion 112 and the plug-in fitting portion 131, the seal 130 is plugged and fixed to the cabinet body 110 to increase the connection area between the seal 130 and the cabinet body 110, thereby preventing the cabinet door 120 from driving the seal 130 off the cabinet body 110 when moving out of the sealing groove 150. Among them, one of the plug-in portion 112 and the plug-in fitting portion 131 is set as a concave portion, and the other is set as a convex portion that cooperates with the concave portion, and this application does not limit this. For example, the plug-in portion 112 can be a convex structure, a groove structure, or a zigzag structure combining concave and convex, and the plug-in fitting portion 131 is adaptively adjusted according to the shape of the plug-in portion 112, and this application does not limit this. By connecting in such a plug-in manner, the engagement area between the sealing member 130 and the cabinet body 110 can be increased, thereby improving the connection stability and preventing the sealing member 130 from falling off.

[0059] See also Figure 4 In some embodiments, in order to further prevent the seal 130 from being driven off by the cabinet door 120, the seal 130 further includes an anti-slip portion 140. The anti-slip portion 140 can be fixed to either the plug-in portion 112 or the plug-in fitting portion 131, and this application does not impose any restrictions. The anti-slip portion 140 can be set as a component such as a bump or a rib, so that during the plug-in fit between the cabinet body 110 and the seal 130, the anti-slip portion 140 can be squeezed between the plug-in portion 112 and the plug-in fitting portion 131, further providing an extrusion force for the connection between the plug-in portion 112 and the plug-in fitting portion 131, so that the plug-in portion 112 and the plug-in fitting portion 131 are better fixed to each other, thereby reducing the loosening and falling off of the seal 130 due to external forces during use, and improving the connection reliability between the cabinet body 110 and the seal 130.

[0060] See also Figures 7 to 9, the anti-slip portion 140 can also be set as an anti-slip fin. As an example, the anti-slip fin can be elastic, and the extension length of the anti-slip fin along the root to the top is not less than the installation gap between the plug-in fitting portion 131 and the plug-in portion 112. Among them, the root 141 of the anti-slip fin can be connected to the plug-in fitting portion 131, so that during the plug-in connection process of the plug-in fitting portion 131, the top 142 of the anti-slip fin is squeezed by the plug-in portion 112 to undergo elastic deformation, so as to fit with the plug-in portion 112 to form surface contact, thereby increasing the friction between the top 142 of the anti-slip fin and the plug-in portion 112, thereby further preventing the seal 130 from falling out.

[0061] In order to facilitate the surface contact between the anti-slip fin and the plug-in portion 112, the cross-sectional area of the root portion 141 of the anti-slip fin can be set to be larger than the cross-sectional area of the top portion 142 of the anti-slip fin, so that when the anti-slip fin is squeezed, the elastic deformation of the top portion of the anti-slip fin is greater than the elastic deformation of the root portion of the anti-slip fin, thereby facilitating the surface contact between the anti-slip fin and the plug-in portion 112. At the same time, when the surface contact is formed, the root portion 141 of the anti-slip fin can also support the top portion 142 of the anti-slip fin, so that the anti-slip fin maintains a certain squeezing force between the plug-in portion 112 and the plug-in fitting portion 131, thereby preventing the seal 130 from falling out.

[0062] In some embodiments, a plurality of anti-detachment fins may be provided to form multiple barriers during the detachment process of the sealing member 130 , thereby preventing the sealing member 130 from detaching.

[0063] like Figures 7 to 9 As shown, in some embodiments, to facilitate plugging and assembling the seal 130 to the inner side wall of the cabinet opening 113, the anti-drop fins can be arranged at an angle relative to the plug-fitting portion 131. For example, the anti-drop fins are arranged at an acute angle from the direction from the root to the top and from the direction from the connecting side 133 to the sealing side 132.

[0064] In this way, when installing the plug-in fitting portion 131 and the plug-in portion 112, the anti-slip fin can be rotated clockwise, so that the overall outer diameter of the anti-slip fin and the plug-in fitting portion 131 shows a gradually decreasing trend, thereby reducing the friction between the top 142 of the anti-slip fin and the plug-in fitting portion 112, so that the plug-in fitting portion 131 can be smoothly plugged into the plug-in fitting portion 112, thereby completing the installation of the seal 130 and the cabinet 110. At the same time, when the plug-in fitting portion 131 is disengaged from the plug-in fitting portion 112, the anti-slip fin can be rotated counterclockwise, so that the overall outer diameter of the anti-slip fin and the plug-in fitting portion 131 shows a continuously increasing trend, thereby increasing the extrusion force between the plug-in fitting portion 131 and the plug-in fitting portion 112, thereby preventing the plug-in fitting portion 131 from disengaging from the plug-in fitting portion 112 and preventing the seal 130 from falling off from the cabinet 110. Therefore, the anti-detachment fins provided in this way can not only facilitate the installation and fixation of the seal 130 and the cabinet 110, but also prevent the seal 130 from falling off the cabinet 110, so that the seal 130 and the cabinet 110 have good connection reliability.

[0065] In other examples, such as Figure 10 As shown, the anti-slip fins can also be set on the plug-in part 112 of the cabinet body 110. At this time, the anti-slip fins are set at an obtuse angle along the inclined direction from the root to the top and the direction from the connecting side 133 to the sealing side 132. This can also achieve easy installation and anti-slip effects between the seal 130 and the cabinet body 110, which will not be elaborated in this application.

[0066] In some embodiments, the seal 130 can be configured in a variety of shapes to accommodate the connection requirements of doors 120 or cabinet bodies 110 of varying shapes. For example, if the cabinet door 120 is curved, the seal 130 can be configured in a curved shape that matches the cabinet door 120, and the sealing groove 150 extending along the length of the seal 130 can also be configured in a curved shape to facilitate installation between the cabinet body 110 and the door 120 of the refrigerator 10. Furthermore, the seal 130 can also be configured in a variety of shapes, such as a straight bar or a combination of a straight bar and a curved bar, without limitation in this application.
