Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, a freezer has a refrigeration compartment inside, which creates a refrigerated environment for storing goods.

[0003] Refrigeration equipment typically includes a cabinet and a door. The cabinet contains a storage compartment, and the door is rotatably connected to the cabinet to open or close the refrigeration compartment used for storing items.

[0004] Current door frames typically consist of a door shell, left and right end caps, an inner door liner, and a door seal. The end caps, located on the left and right sides of the door frame, provide structural support and are connected to the door shell and inner door liner via screws and clips, thus securing the internal components. However, the high cost of end caps increases the overall cost of the door frame. Furthermore, the need for sponges and tape to seal and secure the end caps after assembly further increases material costs and assembly complexity. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigeration device that reduces door costs while providing a good sealing effect through a new door structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; the housing having a refrigeration compartment; and a door covering the opening of the refrigeration compartment. The door includes: a door shell including a door panel disposed on the top surface of the door; door side panels extending from the side edge of the door panel toward the lower side of the door panel; a plurality of door side panels being provided, the plurality of door side panels being circumferentially spaced around the door panel; the door panel and the plurality of door side panels enclosing a foamed space; a notch area being formed between two adjacent door side panels; and a sealing element disposed within the foamed space, the sealing element being disposed at the notch. The inner side of the area is covered by the notch area; the outer wall of the seal is recessed with a snap-fit ​​cavity, which is isolated from the foaming space; a decorative piece is disposed on the outer side of the notch area and covers the notch area, the inner side of the decorative piece extends into the snap-fit ​​cavity through the notch area and snaps with the seal; wherein, the outer wall of the seal is provided with a first sealing wall and a second sealing wall, which are respectively disposed on opposite sides of the snap-fit ​​cavity; the first sealing wall is sealed and fitted with the inner wall of the door side panel on one side of the notch area, and the second sealing wall is sealed and fitted with the inner wall of the door side panel on the other side of the notch area.

[0008] The above technical solution has the following advantages or beneficial effects: The door body is formed by multiple door side panels that bend and extend from the edge of the door panel, and the door side panels and the door panel enclose a foamed space. The door side panels, which bend and extend from the side edge of the door panel toward the lower side of the door panel, replace the end cap structure. A sealing element is set inside the gap area formed between adjacent door side panels, and a first sealing wall and a second sealing wall are formed on the outer wall of the sealing element. The first sealing wall and the second sealing wall respectively seal and fit against the inner wall of the door side panel on both sides of the gap area, thereby forming a sealing interface between the door side panels on opposite sides. This can effectively prevent the foamed space inside the door shell from communicating with the gap area, thus improving the sealing performance of the door body at the gap. Furthermore, a snap-fit ​​cavity is formed on the side of the seal that is isolated from the foaming space. The decorative part is snapped into the snap-fit ​​cavity of the seal by insertion. This not only covers the outside of the notch area and enhances the appearance integrity of the door, but also forms a snap-fit ​​structure between the decorative part and the seal. This installation structure is simple and also helps to further reinforce the position of the seal in the notch area to prevent the seal from shifting. This effectively achieves the sealing effect of the seal on the notch area and effectively isolates the notch area from the foaming space.

[0009] In some embodiments of this application, a cooling device is provided, wherein the groove wall of the snap-fit ​​cavity is provided with snap-fit ​​ribs; the inner wall of the decorative part is provided with snap-fit ​​arms, the snap-fit ​​arms being able to extend into the snap-fit ​​cavity through the notch area and snap-fit ​​with the snap-fit ​​ribs.

[0010] Another technical solution described above has the following advantages or beneficial effects: By setting a snap-fit ​​rib on the groove wall of the snap-fit ​​cavity and a snap-fit ​​arm on the inner wall of the decorative part, the snap-fit ​​arm can elastically engage with the snap-fit ​​rib when inserted into the snap-fit ​​cavity. This creates a snap-fit ​​structure between the sealing element and the decorative part, providing elastic clamping to strengthen the connection. Furthermore, during assembly, the operator only needs to press the decorative part into the notch area for automatic snap-fit ​​positioning. The engaging structure of the snap-fit ​​rib and snap-fit ​​arm simplifies the assembly operation, eliminating the need for additional materials or processes such as screws, tape, and adhesives, thereby reducing assembly time and costs.

[0011] In some embodiments of this application, a cooling device is provided, wherein the snap-fit ​​arm extends from the inner wall of the decorative part toward the interior of the snap-fit ​​cavity, and the end of the snap-fit ​​arm near the inner wall of the decorative part is provided with a hollow hole, and the end of the snap-fit ​​arm away from the inner wall of the decorative part is snapped with the snap-fit ​​rib.

[0012] Another technical solution described above has the following advantages or beneficial effects: A perforated hole is provided at the end of the snap-fit ​​arm near the inner wall of the decorative part, i.e., at the root of the snap-fit ​​arm. This allows the snap-fit ​​arm to achieve a greater range of elastic deformation during insertion into the snap-fit ​​cavity, resulting in smoother deformation and less resistance during installation. This effectively reduces the insertion force required during assembly and avoids the problem of the decorative part being too tight to insert during assembly. Therefore, it improves the tolerance of the assembly between the decorative part and the sealing part, and helps to accommodate minor structural errors.

[0013] In some embodiments of this application, a cooling device is provided, wherein a first guide plate and a second guide plate extend from the inner sidewall of the decorative member toward the inner side of the notch area, and the first guide plate and the second guide plate are arranged at intervals; the first guide plate extends into the snap-fit ​​cavity along one side edge of the notch area, and the first guide plate is clearance-fitted with the corresponding side edge of the notch area; the second guide plate extends into the snap-fit ​​cavity along the other side edge of the notch area, and the second guide plate is clearance-fitted with the corresponding side edge of the notch area.

[0014] Another technical solution described above has the following advantages or beneficial effects: the first guide plate and the second guide plate correspond to the edges on both sides of the notch area, respectively. During the installation of the decorative parts, the first guide plate and the second guide plate can be used to guide the insertion path of the decorative parts, making it easier to align with the snap-fit ​​cavity and insert in the correct direction, thereby improving the convenience of assembling the fittings and seals. Furthermore, the guide plates and the edges of the notch area adopt a clearance fit rather than a tight fit. In this way, even if there are slight dimensional deviations or deformations in the assembly structure between door side panels, seals, or decorative parts, the first guide plate and the second guide plate can still provide a buffer space for assembly tolerances and manufacturing errors, avoiding snap-fit ​​difficulties or structural interference due to tolerance issues, and significantly improving the assembly adaptability and tolerance of the product structure.

[0015] In some embodiments of this application, a cooling device is provided, wherein a first extension wall and a second extension wall are provided on opposite sides of the decorative member; the first extension wall is provided on one side of the notch area and abuts against the outer side wall of the door side panel on one side of the notch area; the second extension wall is provided on the other side of the notch area and abuts against the outer side wall of the door side panel on the other side of the notch area.

[0016] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the first extension wall and the second extension wall form an abutment and limiting relationship with the outer wall of the door side panel on both sides of the notch area during the insertion of the decorative part. In this way, after the insertion is completed, it is beneficial for the decorative part to be more tightly embedded on the outside of the notch area, and it can also effectively limit the displacement of the decorative part and prevent it from sliding or shaking to the left or right, thereby improving the stability of the assembly structure of the decorative part and the door body.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein a first abutting rib is provided at one end of the first extended wall away from the notch area, the first abutting rib protruding toward the corresponding door side panel and abutting against the outer wall of the corresponding door side panel; a second abutting rib is provided at one end of the second extended wall away from the notch area, the second abutting rib protruding toward the corresponding door side panel and abutting against the outer wall of the corresponding door side panel.

[0018] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a first abutting rib on the first extension wall, the first extension wall abuts against the door side panel through the first abutting rib, and providing a second abutting rib on the second extension wall, the second extension wall abuts against the door side panel on the other side through the second abutting rib, the actual contact area between the first extension wall and the second extension wall and the door side panel can be reduced, thereby avoiding the warping stress that is easily caused by large-area fitting, making it easier for the extension wall to release its own stress deformation, thereby effectively suppressing the tendency of the decorative parts to fold outward or buckle outward on the door side panel, and significantly improving the flatness of the appearance and assembly stability of the decorative parts.

[0019] In some embodiments of this application, a cooling device is provided, wherein the door shell further includes a folded edge, the folded edge being bent from the side of the door side panel away from the door panel toward the inner side of the door body; a gap area is formed between adjacent folded edges, the gap area communicating with the notch area; a shielding wall is formed on the side of the sealing member away from the door panel, the shielding wall shielding the gap area, one end of the shielding wall being sealed and fitted with the inner wall of the folded edge on one side of the gap area, and the other end of the shielding wall being sealed and fitted with the inner wall of the folded edge on the other side of the gap area.

[0020] Another technical solution described above has the following advantages or beneficial effects: Since the gap formed between adjacent folded edges constitutes a potential gap and a weak sealing area in the lower structure of the door, a shielding wall is formed by extending from the sealing element, allowing the shielding wall to adhere to the inner wall of the folded edge, thereby directly covering and sealing the gap. Furthermore, one end of the shielding wall extends to the inner side of the folded edge on one side of the gap, sealingly adhering to the folded edge on one side of the gap. The other end of the shielding wall extends to the inner side of the folded edge on the other side of the gap, sealingly adhering to the folded edge on the other side of the gap. This effectively shields and seals the gap between the side edge of the gap and the sealing element, effectively blocking the gap formed between the folded edge and the sealing element, thereby improving the sealing performance of the foam space inside the door.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein the decorative element is provided with a flanged cover, the flanged cover is disposed on the outside of the partition area, the flanged cover is arranged to bend and extend from the side of the decorative element near the folded edge toward the inside of the door body, and the flanged cover is disposed on the outside of the folded edge.

[0022] Another technical solution described above has the following advantages or beneficial effects: After the decorative element and the sealing element are snapped together, the flange cover on the side of the decorative element away from the door panel covers the outside of the shielding wall. Thus, the shielding wall is located on the inside of the folded edge, and the decorative element is located on the outside of the folded edge, forming an inner and outer sandwich structure for the folded edge. The shielding wall seals the inside of the folded edge, and the decorative element, covering the outside of the folded edge, effectively shields the gap between the folded edges, preventing the gap from being exposed and avoiding gaps in the door shell structure or discontinuous outer surfaces that could affect the product's appearance and performance.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein the door shell is provided with a flange, the flange is bent and extended from the door shell toward the notch area, and the opposite ends of the flange are respectively connected to the door side panels on both sides of the notch area; a third extension wall is formed at one end of the decorative member near the door panel, the third extension wall is located outside the flange, and the inner wall of the third extension wall abuts against the outer wall of the flange.

[0024] Another technical solution mentioned above has the following advantages or beneficial effects: the flange reinforcement can form a reinforced structure for the door side panels on both sides of the notch area, thereby enhancing the local rigidity and load-bearing capacity of the door shell at the notch area. Furthermore, by providing a third extension wall at one end of the decorative element near the door panel, which abuts against the outer wall of the flange reinforcement, the decorative element is tightly fitted to the flange reinforcement through the third extension wall, thus providing support for the flange reinforcement. This further improves the structural strength of the notch area, reduces changes in the sealing gap caused by structural deformation, and enhances the overall structural stability of the door.

[0025] In some embodiments of this application, a refrigeration device is provided. The door body further includes a door insert, which covers the side of the door side panel away from the door panel. The peripheral edge of the door insert is connected to the side of the folded edge away from the door side panel. A door sealing groove extending into the foaming space is provided at the peripheral edge of the door insert, and the door sealing groove is located inside the folded edge. An isolation wall is provided on the side of the sealing member facing the foaming space, and a snap-fit ​​cavity is located on the side of the isolation wall away from the foaming space. A support plate is provided on the side of the isolation wall facing the foaming space, and the support plate is arranged opposite to the groove wall of the door sealing groove and has a clearance fit with the groove wall of the door sealing groove.

[0026] Another technical solution described above has the following advantages or beneficial effects: By providing an isolation wall on the seal, with one side of the isolation wall facing the foaming space and the other side having a snap-fit ​​cavity, the isolation wall isolates the foaming space from the gap area. When the seal is installed inside the door housing, leakage of the foaming material in the foaming space through the gap area can be effectively prevented. Moreover, due to the gap fit between the support plate and the door seal groove wall, a flow guide space is provided for the flow and filling of the foaming material, allowing the foaming material to quickly penetrate into the gap area between the door seal groove wall and the support plate. Furthermore, by utilizing the solidification characteristics of the foaming material after filling, the connection strength and stability between the support plate and the door seal groove can be enhanced, thereby effectively preventing the seal from loosening or falling off.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator or other refrigeration cabinet. The following uses a freezer as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0050] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application; Figure 2 for Figure 1 A schematic diagram of one state.

[0051] like Figure 1 and Figure 2 As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigerator. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0052] In some embodiments, multiple refrigeration compartments 101 can serve as independent storage spaces, such as freezers, refrigerators, and variable temperature compartments, to meet different refrigeration needs such as freezing, refrigeration, and variable temperature depending on the type of food, and to store items that require refrigeration or freezing. The multiple refrigeration compartments 101 can be arranged vertically or horizontally.

[0053] The refrigerator may include a refrigerator liner (not shown in the figure). The refrigerator liner may be located inside the refrigerator body 1. The refrigerator liner may contain a refrigeration compartment 101.

[0054] like Figure 2 As shown, in some embodiments, the refrigeration device includes a door 2. The door 2 is disposed above the housing 1 and covers the opening of the refrigeration compartment 101 for opening and closing the refrigeration compartment 101 with the upper opening.

[0055] It should be noted that multiple doors 2 can be installed. Each door 2 can be installed in a one-to-one correspondence with a refrigeration room 101. Multiple doors 2 can open and close a single refrigeration room 101 simultaneously. A single door 2 can also open and close multiple refrigeration rooms 101 simultaneously.

[0056] In some embodiments, the refrigeration system may include a compressor (not shown). The compressor, as the power source of the refrigeration cycle, draws in low-temperature, low-pressure refrigerant gas and compresses it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0057] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser receives refrigerant flowing from the compressor, cools the high-temperature, high-pressure refrigerant gas from the compressor, and converts it into a liquid state. The condenser transfers heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0058] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0059] In some embodiments, the refrigeration system may include an evaporator (not shown). A throttling device delivers a throttled and depressurized refrigerant into the evaporator. The evaporator is used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0060] In some embodiments, the compressor, condenser, throttling device, and evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0061] Figure 3 for Figure 1 A three-dimensional schematic diagram of the central gate; Figure 4 for Figure 3 A three-dimensional diagram from another perspective; Figure 5 for Figure 3 A three-dimensional schematic diagram of the middle door shell.

[0062] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the door body 2 may include a door shell 21. The door shell 21 serves as the main frame of the door body 2. A foamed space 201 may be formed within the door shell 21, and foamed material may be filled in the space. The foamed material has properties such as heat insulation and heat preservation, which can effectively prevent the cold air in the refrigeration chamber 101 from exchanging heat with the external environment, thereby maintaining a constant low temperature environment in the refrigeration chamber 101 and ensuring the refrigeration effect of the refrigeration device.

[0063] like Figure 2As shown, in some embodiments, the door housing 21 may include a door panel 211. The door panel 211 is disposed on the top surface of the door body 2, thereby covering the upper opening of the refrigeration compartment 101. It should be noted that in some other embodiments, the refrigeration compartment 101 may have a front opening, and the door body 2 may be disposed on the front side of the refrigeration compartment 101. Correspondingly, the door panel 211 may cover the front opening.

[0064] like Figure 3 and Figure 5 As shown, in some embodiments, the door housing 21 may include door side panels 212. The door side panels 212 extend from the side edge of the door panel 211 toward the lower side of the door panel 211. Multiple door side panels 212 are provided, and the multiple door side panels 212 are arranged circumferentially around the door panel 211. The door panel 211 and the multiple door side panels 212 enclose a foaming space 201.

[0065] In existing technologies, the door body 2 relies on end caps for structural support and to secure internal components, but these end caps are costly. In this application, the door shell 21 consists of a door panel 211 and multiple door side panels 212. The door side panels 212 extend from the side edges of the door panel 211 downwards, and the multiple door side panels 212 are arranged circumferentially around the door panel 211. This eliminates the need for the end caps used in existing door bodies 2, thereby reducing the production and manufacturing costs of the door body 2.

[0066] like Figure 3 As shown, in some embodiments, the door panel 211 may be rectangular. The four sides of the door panel 211 are bent and extended toward the lower side of the door panel 211 to form door side panels 212, and four door side panels 212 may be provided accordingly.

[0067] In some embodiments, the door shell 21 may be made of sheet metal and may be formed by stamping or other integral forming methods to make the door body 2 form a structure in which the door side panel 212 surrounds the periphery of the door shell 21.

[0068] like Figure 4 As shown, in some embodiments, the door shell 21 may include a door insert 24. The door insert 24 covers the side of the door side panel 212 away from the door panel 211, and the peripheral edge of the door insert 24 is connected to the door side panel 212. The door insert 24 is located on the side of the door panel 211 facing the refrigeration compartment 101, and the door insert 24 covers the bottom opening formed by the plurality of door side panels 212. Thus, the door insert 24, the door side panel 212, and the door panel 211 enclose a foaming space 201.

[0069] Figure 6 for Figure 4 An exploded image.

[0070] like Figure 5 and Figure 6 As shown, in some embodiments, a notch area 202 may be formed between two adjacent door side panels 212. The door body 2 may include a seal 22. The seal 22 is disposed within the foaming space 201, and is located inside the notch area 202 and covers the notch area 202. By providing a seal 22 inside the notch area 202 between the door side panels 212, the seal 22 serves to cover the notch area 202, preventing the foaming material in the foaming space 201 from leaking directly to the outside of the door body 2 through the notch area 202.

[0071] It should be noted that a door side panel 212 extends outward from the periphery of the door panel 211. The door side panel 212 extends toward one of the panels of the door panel 211 after being folded. Since there is usually a gap space of notch area 202 between adjacent door side panels 212 in the current processing method, the notch area 202 can be effectively blocked by setting the sealing element 22 on the inside of the notch area 202.

[0072] like Figure 4 and Figure 6 As shown, in some embodiments, multiple seals 22 may be provided, and the number of seals 22 may correspond to the number of notch areas 202, so that multiple seals 22 can respectively block the notch areas 202. Specifically, four seals 22 may be provided to correspond to the number of notch areas 202.

[0073] In some other embodiments, the seal 22 may be in the form of a frame structure. The frame-structured seal 22 may be nested inside the door side panel 212 and may accordingly cover the gap area 202 between adjacent door side panels 212.

[0074] like Figure 4 and Figure 6 As shown, in some embodiments, the door body 2 may include a decorative element 23, which may be disposed on the outside of the notch area 202 and snapped into the seal 22. The decorative element 23 is correspondingly located on the outside of the seal 22. By being disposed on the outside of the seal 22, the exposed portion of the notch area 202 can be covered, thus not only filling the notch area 202 but also beautifying the appearance of the door body 2.

[0075] Figure 7 for Figure 4 A cross-sectional view; Figure 8 for Figure 4 Another cross-sectional view; Figure 9 for Figure 6 A schematic diagram of the central sealing element.

[0076] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the outer wall of the seal 22 facing the notch area 202 may be recessed with a snap-fit ​​cavity 203, which communicates with the notch area 202 and is isolated from the foaming space 201. The decorative member 23 is disposed on the outside of the notch area 202 and covers the notch area 202. The inner side of the decorative member 23 extends into the snap-fit ​​cavity 203 through the notch area 202 and snaps into the seal 22.

[0077] Specifically, the outer wall of the seal 22 covers the notch area 202, and a snap-fit ​​cavity 203 is formed on the side facing away from the foam space 201. The seal 22 isolates the notch area 202 from the foam space 201. Moreover, the snap-fit ​​cavity 203 communicates with the notch area 202, allowing the decorative piece 23 to extend through the notch area 202 and snap into the snap-fit ​​cavity 203. Thus, a snap-fit ​​connection is formed between the decorative piece 23 and the seal 22. On the one hand, this fixes the decorative piece 23 and covers the notch area 202 to form a complete exterior edge for the door body 2, while also beautifying the appearance of the door body 2 and enhancing its visual consistency and aesthetics. On the other hand, it also fixes the seal 22 at the notch area 202 to prevent the seal 22 from shifting, thereby affecting its isolation effect on the notch area 202 and the foam space 201, as well as its covering effect on the notch area 202.

[0078] like Figure 8 and Figure 9 As shown, in some embodiments, a first sealing wall 221 and a second sealing wall 222 may be provided on the outer wall of the seal 22. The first sealing wall 221 and the second sealing wall 222 are respectively disposed on opposite sides of the snap-fit ​​cavity 203. The first sealing wall 221 is sealed and fitted with the inner wall of the door side panel 212 on one side of the notch area 202, and the second sealing wall 222 is sealed and fitted with the inner wall of the door side panel 212 on the other side of the notch area 202.

[0079] The resealing element 22 has a first sealing wall 221 and a second sealing wall 222 on its outer wall. The first sealing wall 221 is fitted to the inner wall of the door side panel 212 on one side of the notch area 202, and the second sealing wall 222 is fitted to the inner wall of the door side panel 212 on the other side of the notch area 202. This seals the inner walls of the door side panels 212 on both sides of the notch area 202, forming a sealing interface between the door side panels 212. This effectively prevents the foaming space 201 inside the door shell 21 from communicating with the notch area 202. Regarding the assembly structure of the sealing element 22 and the door shell 21, since the first sealing wall 221 and the second sealing wall 222 are respectively sealed to both sides of the notch area 202, the two sides of the sealing element 22 can form a clamping structure with the door side panel 212. This effectively restricts the displacement of the sealing element 22 during assembly with the door shell 21, further improving the assembly stability and positioning accuracy of the sealing element 22.

[0080] In existing technologies, the door body 2 of a refrigeration device typically includes components such as a door shell, left and right end caps, an inner liner, and a door seal. The end caps, serving as the left and right closures of the door body 2, function to secure the internal components and support the structure. However, this approach presents significant technical drawbacks: firstly, the end caps are usually independent components, resulting in higher manufacturing costs and increasing the overall cost of the door body 2; secondly, the connection between the end caps and the door shell and inner liner often requires screws, clips, and other methods, supplemented by sponge and tape for sealing and securing. This not only incurs additional material costs but also complicates the assembly process, reduces efficiency, and increases the difficulty of production operations.

[0081] In this application, the door body 2 is formed by bending and extending multiple door side panels 212 from the edge of the door panel 211. The door side panels 212 and the door panel 211 enclose a foaming space 201. The door side panels 212, which are bent and extended from the side edge of the door panel 211 toward the lower side of the door panel 211, replace the end cap structure, which can reduce the manufacturing cost of the door body 2. Furthermore, a sealing element 22 is provided inside the gap area 202 formed between adjacent door side panels 212, and a first sealing wall 221 and a second sealing wall 222 are formed on the outer wall of the sealing element 22. The first sealing wall 221 and the second sealing wall 222 are respectively sealed and fitted to the inner walls of the door side panels 212 on both sides of the gap area 202, thereby forming a sealing interface between the door side panels 212 on opposite sides. This can effectively prevent the foaming space 201 in the door shell 21 from communicating with the gap area 202, thereby improving the sealing performance of the door body 2 at the gap. Furthermore, the first sealing wall 221 and the second sealing wall 222 can serve as the boundary of the foaming space 201, playing a role in restricting and guiding the foaming material during the foaming and filling process of the door body 2. This prevents the foaming material from leaking into the gap area 202 through the seal 22, ensuring the cleanliness and integrity of the foaming molding and improving the structural filling quality of the refrigeration door body 2. In addition, since the first sealing wall 221 and the second sealing wall 222 are respectively sealed and attached to both sides of the gap area 202, the displacement of the seal 22 can be effectively restricted during the assembly structure with the door shell 21, thereby enabling the seal 22 to be stably positioned between the door side panels 212.

[0082] Furthermore, a snap-fit ​​cavity 203 is formed on the side of the seal 22 that is isolated from the foaming space 201. The decorative piece 23 is snapped into the snap-fit ​​cavity 203 of the seal 22 by insertion. This not only covers the outside of the notch area 202 and enhances the appearance integrity of the door 2, but also forms a snap-fit ​​structure between the decorative piece 23 and the seal 22. This installation structure is simple and also helps to further reinforce the position of the seal 22 in the notch area 202 to prevent the seal 22 from shifting. This effectively achieves the covering effect of the seal 22 on the notch area 202 and effectively isolates the notch area 202 from the foaming space 201.

[0083] In some embodiments, the seal 22 may be made of a flexible material, which can then be effectively attached to the door side panel 212.

[0084] like Figure 4 and Figure 6 As shown, in some embodiments, multiple decorative elements 23 may be provided. Multiple decorative elements 23 may be respectively provided on the outer side of the notch area 202. Specifically, four decorative elements 23 may be provided corresponding to the number of notch areas 202, so that each notch area 202 on the door body 2 can be provided with a decorative element 23 for covering and decoration.

[0085] like Figure 7 and Figure 9 As shown, in some embodiments, the groove wall of the snap-fit ​​cavity 203 is provided with snap-fit ​​ribs 223. The snap-fit ​​ribs 223 may be provided to protrude relative to the groove of the snap-fit ​​cavity 203.

[0086] The inner wall of the decorative part 23 may be provided with a snap-fit ​​arm 231. The snap-fit ​​arm 231 may extend from the inner wall of the decorative part 23 toward the sealing part 22 and has a certain length. The snap-fit ​​arm 231 may extend into the snap-fit ​​cavity 203 through the notch area 202 and snap-fit ​​with the snap-fit ​​rib 223.

[0087] Specifically, by providing a snap-fit ​​rib 223 on the groove wall of the snap-fit ​​cavity 203 and a snap-fit ​​arm 231 on the inner wall of the decorative part 23, the snap-fit ​​arm 231 can elastically engage with the snap-fit ​​rib 223 when inserted into the snap-fit ​​cavity 203. This creates a snap-fit ​​structure between the sealing part 22 and the decorative part 23, providing both structural limitation and elastic clamping to strengthen the connection. Furthermore, during assembly, the operator only needs to press the decorative part 23 into the notch area 202 for automatic snap-fit ​​positioning. The engagement structure of the snap-fit ​​rib 223 and the snap-fit ​​arm 231 simplifies the assembly operation, eliminating the need for additional materials or processes such as screws, tape, or adhesives, thereby reducing assembly time and costs.

[0088] Figure 10 for Figure 6 A schematic diagram of the decorative component.

[0089] like Figure 7 and Figure 10 As shown, in some embodiments, the snap-fit ​​arm 231 can extend from the inner wall of the decorative member 23 toward the interior of the snap-fit ​​cavity 203. One end of the snap-fit ​​arm 231 near the inner wall of the decorative member 23 has a perforated hole 204, and the other end of the snap-fit ​​arm 231 away from the inner wall of the decorative member 23 is snapped into the snap-fit ​​rib 223. The end of the snap-fit ​​arm 231 away from the decorative member 23 can be configured as a snap-fit ​​structure.

[0090] The snap-fit ​​arm 231 has a perforated hole 204 at its root near the inner wall of the decorative element 23. This allows the snap-fit ​​arm 231 to undergo greater elastic deformation during insertion into the snap-fit ​​cavity 203, resulting in smoother deformation, less resistance, and reduced insertion force. This avoids the problem of the decorative element 23 being too tight to insert during assembly. This improves the tolerance of the assembly between the decorative element 23 and the sealing element 22, and helps accommodate minor structural errors. Furthermore, the snap-fit ​​arm 231 rebounds quickly after insertion, enhancing the snap-fit ​​clamping force between the snap-fit ​​wall and the snap-fit ​​arm 231, thereby improving the connection strength and vibration resistance between the decorative element 23 and the door body 2.

[0091] like Figure 7 and Figure 10 As shown, in some embodiments, two snap-fit ​​ribs 223 may be provided, and the two ribs may be provided on opposite sides of the groove wall of the snap-fit ​​cavity 203. Correspondingly, two snap-fit ​​arms 231 may be provided. The two snap-fit ​​arms 231 may be provided on both sides of the decorative part 23 and are provided one-to-one with the snap-fit ​​ribs 223. In this way, a double snap-fit ​​fixing structure can be formed between the decorative part 23 and the sealing part 22, which can effectively improve the positioning stability of the decorative part 23 in multiple directions and greatly reduce the risk of the decorative part 23 loosening, shifting or falling off during external impact or long-term use.

[0092] In some embodiments, two snap-fit ​​arms 231 may be provided, one snap-fit ​​arm 231 having a perforation 204 and the other snap-fit ​​arm 231 not having a perforation 204. By setting the two snap-fit ​​arms 231 to different structural forms, the snap-fit ​​arm 231 with the perforation 204 has a higher elastic deformation capacity, while the snap-fit ​​arm 231 without the perforation 204 maintains relative rigidity and stability. In this way, one snap-fit ​​arm 231 can more easily pass over the snap-fit ​​rib 223 and automatically spring back and lock, while the other snap-fit ​​arm 231 acts as a load-bearing frame and anti-deformation function. This not only further improves the fault tolerance rate of the snap-fit ​​between the decorative part 23 and the door body 2, thus adapting to minor errors in the structural dimensions of the door body 2 and the sealing part 22, but also enhances the stability and firmness of the entire snap-fit ​​structure between the decorative part 23 and the sealing part 22.

[0093] like Figure 8 and Figure 10 As shown, in some embodiments, a first guide plate 232 and a second guide plate 233 extend from the inner sidewall of the decorative member 23 toward the inner side of the notch area 202. The first guide plate 232 and the second guide plate 233 can be arranged on the decorative member 2 at a relatively interval. The first guide plate 232 can extend into the snap-fit ​​cavity 203 along one side edge of the notch area 202, and the second guide plate 233 can extend into the snap-fit ​​cavity 203 along the other side edge of the notch area 202.

[0094] The first guide plate 232 and the second guide plate 233 correspond to the edges on both sides of the notch area 202, respectively. During the installation of the decorative part 23, the first guide plate 232 and the second guide plate 233 can be used to guide the insertion path of the decorative part 23, making it easier to align with the snap-fit ​​cavity 203 and insert it in the correct direction, thereby improving the convenience of assembling the fitting and the seal 22.

[0095] like Figure 8 As shown, in some embodiments, the first guide plate 232 is clearance-fitted with the side edge of the corresponding notch area 202. And the second guide plate 233 is clearance-fitted with the side edge of the corresponding notch area 202.

[0096] Furthermore, after the decorative part 23 is inserted into the snap-fit ​​cavity 203, the guide plate forms a clearance fit with the edge of the notch area 202, providing a certain limiting and positioning function without interfering with the decorative part 23 and the seal 22. More importantly, the guide plate uses a clearance fit rather than a tight fit with the edge of the notch area 202. This allows the first guide plate 232 and the second guide plate 233 to provide a buffer for assembly tolerances and manufacturing errors even if there are minor dimensional deviations or deformations in the assembly structure between the door side panels 212, the seal 22, or the decorative part 23. Specifically, even if there are minor dimensional deviations or deformations in the door body 2 or the decorative part 23, the first guide plate 232 and the second guide plate 233 can still smoothly guide the decorative part 23 into place, avoiding snap-fit ​​difficulties or structural interference due to tolerance issues, significantly improving the assembly adaptability and tolerance of the product structure.

[0097] In some embodiments, any one of the multiple decorative elements 23 can be snapped into each of the snap-fit ​​cavities 203. Because the first guide plate 232 and the corresponding notch area 202 have a clearance fit, and the second guide plate 233 and the corresponding notch area 202 also have a clearance fit, the multiple decorative elements 23 are interchangeable; that is, each decorative element 23 can reliably snap into any of the snap-fit ​​cavities 203, thereby effectively improving the versatility of the decorative elements 23. This simplifies installation and further improves installation efficiency.

[0098] like Figure 8 As shown, in some embodiments, the decorative element 23 may have a first extension wall 234 and a second extension wall 235 on opposite sides. The first extension wall 234 is located on one side of the notch area 202 and abuts against the outer wall of the door side panel 212 on one side of the notch area 202. The second extension wall 235 is located on the other side of the notch area 202 and abuts against the outer wall of the door side panel 212 on the other side of the notch area 202.

[0099] The decorative element 23 has a first extension wall 234 on one of its two sides, which can extend along the door side panel 212 on one side of the notch area 202. The decorative element 23 has a second extension wall 235 on the other side, which can extend along the door side panel 212 on the other side of the notch area 202.

[0100] During the insertion of the decorative piece 23, the first extension wall 234 and the second extension wall 235 respectively form an abutment and limiting relationship with the outer wall of the door side panel 212 on both sides of the notch area 202. In this way, after the insertion is completed, the decorative piece 23 is more tightly embedded on the outside of the notch area 202, and the displacement of the decorative piece 23 can be effectively restricted to prevent it from sliding or shaking to the left or right, thereby improving the assembly structure stability of the decorative piece 23 and the door body 2.

[0101] like Figure 8 and Figure 10 As shown, in some embodiments, the end of the first extension wall 234 away from the notch area 202 may be provided with a first abutment rib 236. The first abutment rib 236 protrudes towards the corresponding door side panel 212 and abuts against the outer wall of the corresponding door side panel 212. The end of the second extension wall 235 away from the notch area 202 is provided with a second abutment rib 237. The second abutment rib 237 protrudes towards the corresponding door side panel 212 and abuts against the outer wall of the corresponding door side panel 212.

[0102] During the engagement of the decorative piece 23 with the door side panel 212, the first extension wall 234 and the second extension wall 235 are prone to warping or outward turning along the outer surface of the door side panel 212 due to uneven stress transmission or slippage, which can lead to the dislocation or deformation of the decorative piece 23. In this embodiment, by providing a first abutting rib 236 on the first extension wall 234, the first extension wall 234 abuts against the door side panel 212 through the first abutting rib 236, and by providing a second abutting rib 237 on the second extension wall 235, the second extension wall 235 abuts against the door side panel 212 on the other side through the second abutting rib 237, the actual contact area between the first extension wall 234 and the second extension wall 235 and the door side panel 212 can be reduced. This avoids the warping stress that is easily caused by large-area fitting, and makes it easier for the extension wall to release its own stress deformation. This effectively suppresses the tendency of the decorative piece 23 to turn outward or buckle on the door side panel 212, and significantly improves the flatness and assembly stability of the appearance of the decorative piece 23.

[0103] like Figure 5 and Figure 7As shown, in some embodiments, the door shell 21 may include a folded edge 213. The folded edge 213 is bent inward from the side of the door side panel 212 away from the door panel 211 toward the inside of the door body 2. A gap area 205 is formed between adjacent folded edges 213, and the gap area 205 communicates with the notch area 202. A shielding wall 224 is formed on the side of the seal 22 away from the door panel 211, and the shielding wall 224 shields the gap area 205. One end of the shielding wall 224 is sealed and fitted to the inner wall of the folded edge 213 on one side of the gap area 205, and the other end of the shielding wall 224 is sealed and fitted to the inner wall of the folded edge 213 on the other side of the gap area 205.

[0104] Specifically, the folded edge 213 is directly bent from the side of the door side panel 212 away from the door panel 211 towards the inside of the door body 2, forming a connection and support structure for other structures of the door body 2. Since the gap area 205 formed between adjacent folded edges 213 constitutes a potential gap and weak sealing area in the lower structure of the door body 2, leakage of the foam space 201 inside the door body 2 is likely to occur. By extending the sealing element 22 to form a shielding wall 224, the shielding wall 224 is made to fit against the inner wall of the folded edge 213, thereby directly covering and sealing the gap area 205.

[0105] Furthermore, one end of the shielding wall 224 extends to the inner side of the folded edge 213 on one side of the partition area 205, and one end of the shielding wall 224 is sealed and fitted with the folded edge 213 on one side of the partition area 205. The other end of the shielding wall 224 extends to the inner side of the folded edge 213 on the other side of the partition area 205, and the other end of the shielding wall 224 is sealed and fitted with the folded edge 213 on the other side of the partition area 205. This effectively shields and seals the gap between the side edge of the partition area 205 and the seal 22, effectively blocking the gap formed between the folded edge 213 and the seal 22, thereby improving the sealing performance of the foam space 201 inside the door body 2.

[0106] like Figure 5 As shown, in some embodiments, multiple folded edges 213 may be provided. Each of the multiple folded edges 213 corresponds to a door side panel 212 folded together.

[0107] like Figure 4 and Figure 6 As shown, in some embodiments, the door insert 24 can be installed on the side of the door side panel 212 away from the door panel 211, and the peripheral edge of the door insert 24 is connected to the side of the folded edge 213 away from the door side panel 212. In this way, the folded edge 213 forms a structure that fixes the door shell 21 and the door insert 24 together, which can support the door insert 24 and connect it to the door shell 21.

[0108] like Figure 7 and Figure 10As shown, in some embodiments, the decorative element 23 may be provided with a flange cover 238. The flange cover 238 is provided on the outside of the partition area 205. The flange cover 238 is arranged by bending and extending from the side of the decorative element 23 near the folded edge 213 toward the inside of the door body 2. The flange cover 238 is provided on the outside of the folded edge 213.

[0109] When the decorative element 23 and the sealing element 22 are engaged, the flange cover 238 on the side of the decorative element 23 away from the door panel 211 covers the outside of the shielding wall 224. Specifically, the shielding wall 224 is located on the inside of the folded edge 213, and the decorative element 23 is located on the outside of the folded edge 213. In this way, an inner and outer sandwich structure can be formed for the folded edge 213. The shielding wall 224 abuts against the inside of the folded edge 213 to seal it, and the decorative element 23 covers the outside of the folded edge 213 to effectively shield the gap area 205 between the folded edges 213, so that the gap area 205 is no longer exposed to the outside, avoiding gaps in the door shell 21 structure or discontinuous outer surface that would affect the product's appearance and performance.

[0110] In some embodiments, the flange cover 238 can serve as a natural extension of the decorative part 23, and its molding can be achieved during the integral injection molding process of the decorative part 23 without the need for additional independent components, which helps to reduce production costs and complexity.

[0111] In some embodiments, the flap cover 238 may abut against the outer side of the folded edge 213, which may further cover the gap between the decorative piece 23 and the folded edge 213.

[0112] like Figure 7 and Figure 10 As shown, in some embodiments, the door shell 21 may be provided with a flange 214. The flange 214 is bent and extended from the side of the door shell 21 toward the notch area 202, and its two ends are respectively connected to the door side panels 212 on both sides of the notch area 202. By having a flange 214 bent and extended from the side of the door shell 21 toward the notch area 202, and its two ends being respectively connected to the door side panels 212 on both sides of the notch area 202, a reinforcement structure for the door side panels 212 on both sides of the notch area 202 can be formed, thereby enhancing the local rigidity and load-bearing capacity of the door shell 21 at the notch area 202, effectively preventing the notch area 202 from deforming, warping or being damaged due to stress concentration, and improving the overall structural stability and durability of the door body 2.

[0113] In some embodiments, a third extension wall 239 may be formed at one end of the decorative member 23 near the door panel 211. The third extension wall 239 is located on the outside of the flange 214, and the inner wall of the third extension wall 239 abuts against the outer wall of the flange 214.

[0114] Specifically, by providing a third extension wall 239 at one end of the decorative piece 23 near the door panel 211, the third extension wall 239 abuts against the outer wall of the flange 214, so that the decorative piece 23 fits tightly with the flange 214 through the third extension wall 239, thereby supporting the flange 214, which further improves the structural strength of the notch area 202, reduces the change in sealing gap caused by structural deformation, and improves the overall structural stability of the door body 2.

[0115] like Figure 4 and Figure 6 As shown, in some embodiments, the door 2 may include a door seal 25. The door seal 25 may be disposed at the peripheral edge of the door liner 24. When the door 2 is closed over the opening of the refrigeration chamber 101, the door seal 25 can seal the gap between the door 2 and the cabinet 1, preventing the cold air in the refrigeration chamber 101 from leaking through the gap between the door 2 and the cabinet 1, thereby improving the heat preservation performance of the refrigeration device.

[0116] In some embodiments, the door seal 25 may be a flexible frame structure, which is then arranged around the periphery of the door liner 24. When the door 2 covers the opening of the refrigeration compartment 101, the door seal 25 may flexibly abut against the door 2 and the cabinet 1.

[0117] like Figure 7 As shown, in some embodiments, a door sealing groove 206 extending into the foaming space 201 may be provided at the peripheral edge of the door insert 24. The door sealing groove 206 is located on the inner side of the folded edge 213. The door sealing groove 206 is adapted to the door seal, allowing the door seal to be nested within the door sealing groove 206, thereby connecting to the peripheral edge of the door insert 24.

[0118] A partition wall 225 may be provided on the side of the sealing element 22 facing the foaming space 201. The snap-fit ​​cavity 203 is located on the side of the partition wall 225 away from the foaming space 201. A support plate 226 is provided on the side of the partition wall 225 facing the foaming space 201. The support plate 226 is arranged opposite to the groove wall of the door sealing groove 206 and is in clearance fit with the groove wall of the door sealing groove 206.

[0119] Specifically, by providing an isolation wall 225 on the sealing element 22, with one side of the isolation wall 225 facing the foaming space 201 and the other side having a snap-fit ​​cavity 203, the isolation wall 225 isolates the foaming space 201 from the notch area 202. When the sealing element 22 is installed inside the door shell 21, it can effectively prevent the foaming material in the foaming space 201 from leaking through the notch area 202.

[0120] Furthermore, during the injection of the foaming material into the foaming space 201, the gap fit between the support plate 226 and the door seal groove 206 provides a guiding space for the flow and filling of the foaming material. This allows the foaming material to quickly penetrate into the gap area between the door seal groove 206 and the support plate 226 by relying on its own expansion force, forming an effective interface filling layer. Moreover, by utilizing the solidification characteristics of the foaming material after filling, the connection strength and stability between the support plate 226 and the door seal groove 206 can be enhanced, thereby effectively preventing the seal 22 from loosening or falling off.

[0121] In addition, since there are inevitably certain manufacturing tolerances between the various parts of the door body 2 in actual production, by setting a gap fit structure between the support plate 226 and the groove wall of the door sealing groove 206, foam material can be used to fill and form gaps caused by dimensional errors, thereby improving the fault tolerance rate of the door body 2 assembly structure.

[0122] Figure 11 for Figure 9 A schematic diagram of the seal from another perspective.

[0123] like Figure 7 and Figure 11 As shown, in some embodiments, the side wall of the door sealing groove 206 is opposite to the partition wall 225 and has a clearance fit.

[0124] Specifically, the bottom surface of the door sealing groove 206 is fitted with the support plate 226 with a clearance, and the side surface of the door sealing groove 206 is fitted with the isolation wall 225 with a clearance. The gaps between the two are connected, so when the foaming material is injected into the foaming space 201, the foaming material can be quickly filled through the gaps between the door sealing groove 206 and the support plate 226, and the gaps between the door sealing groove 206 and the isolation wall 225, effectively avoiding the problem of cavities or incomplete filling inside the door body 2, thereby improving the thermal insulation performance and structural stability of the entire door body 2.

[0125] like Figure 11 As shown, in some embodiments, two support plates 226 may be provided, and the two support plates 226 may be spaced apart on the side of the isolation wall 225 facing the foaming space 201. In this way, the installer does not need to distinguish the installation direction of the seal 22 during the installation of the door body 2, thus avoiding installation errors and improving installation efficiency.

[0126] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
