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, display cases have refrigerated compartments inside, creating a refrigerated environment for storing items.

[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] The door body includes a door shell, a door frame set inside the door shell, and reinforcing iron set inside the door frame. Currently, the design of forming a door handle by recessing the door frame can effectively prevent stress concentration at the connection between the handle and the door frame caused by split handles. However, after the door handle is formed by recessing the door frame, the fit between the reinforcing iron and the door frame is not good, which can easily affect the overall strength and sealing performance of the door. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigeration device that can improve the structural strength of the door frame and the reinforcing iron, thereby helping to prevent the door from deforming during foaming or daily use.

[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; a door covering the opening of the refrigeration compartment; the door including: a door panel disposed on the front side of the door; a door frame disposed on the back side of the door panel, the door frame including: a door side panel disposed on the peripheral edge of the back side of the door panel, the door side panel having a recessed handle groove facing the inside of the door; a first connecting plate extending from the side of the door side panel near the door panel toward the inside of the door, the first connecting plate being affixed to the back of the door panel; a reinforcing member disposed on the inner wall of the door side panel, the reinforcing member including: a reinforcing plate affixed to the inner side wall of the door side panel opposite to the handle groove; a support plate extending from the reinforcing plate toward the door panel, the side of the support plate near the door panel abutting against the back of the first connecting plate.

[0008] The above technical solution has the following advantages or beneficial effects: By setting a reinforcing member on the inner wall of the door side panel, the reinforcing member includes a reinforcing plate and a supporting plate. The reinforcing plate is attached to the inner side wall of the door side panel opposite to the handle groove, which directly enhances the structural strength of the handle groove and improves its resistance to deformation. The supporting plate extends from the reinforcing plate toward the door panel, and the side of the supporting plate near the door panel abuts against the back of the first connecting plate. This means that the reinforcing member provides support not only in the thickness direction of the door side panel but also forms a supporting structure in the front-rear direction of the door. Specifically, when the door is subjected to external force, the force on the handle groove side wall can be transmitted to the supporting plate through the reinforcing plate. Since the supporting plate can abut against the first connecting plate, the external force can be dispersed and transmitted to other parts of the door, avoiding excessive local stress and effectively improving the overall strength of the door.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein the reinforcing member includes a first supporting rib, the first supporting rib being disposed on the side of the supporting plate near the first connecting plate, and the first supporting rib being attached to and supported on the back of the first connecting plate.

[0010] The above technical solution has the following advantages or beneficial effects: By providing a first supporting rib on the side of the support plate near the first connecting plate, the first supporting rib can provide support and reinforcement for the entire reinforcing member. Specifically, the first supporting rib is fitted against the back of the first connecting plate, thereby increasing the contact area between the reinforcing member and the first connecting plate. When one side of the handle groove is subjected to force, the force on the side wall of the handle groove can be transferred to the support plate through the reinforcing plate, and the stress can be further dispersed through the first supporting rib. This can more effectively avoid excessive local stress and provide better support for the door side panel, thereby improving the overall structural strength of the door.

[0011] In some embodiments of this application, a refrigeration device is provided. The door frame includes a second connecting plate disposed on the side of the door side panel away from the first connecting plate, and the second connecting plates are spaced apart on the back side of the first connecting plate. The door body also includes a door insert, which covers the side of the door frame away from the door panel, and the peripheral edge of the door insert is connected to the back side of the second connecting plate. A reinforcing member is disposed between the first connecting plate and the second connecting plate, and the side of the support plate away from the reinforcing plate abuts against the rear wall of the first connecting plate, and the side of the reinforcing plate away from the support plate abuts against the front wall of the second connecting plate.

[0012] The above technical solution has the following advantages or beneficial effects: By placing the reinforcing member between the first connecting plate and the second connecting plate, the front end of the reinforcing member abuts against the first connecting plate via a support plate, and the rear end of the reinforcing member abuts against the second connecting plate via a reinforcing plate, a multi-point support structure for the door side panel is formed. When the user pulls or pushes the handle groove, the external force will first act on the handle groove area of ​​the door side panel. At this time, the reinforcing plate is in contact with the inner wall of the door side panel and can directly share part of the load. Furthermore, the support plate extends the force path to the first connecting plate, and the reinforcing plate guides the force to the second connecting plate. Moreover, since the support plate and the first connecting plate, and the reinforcing plate and the second connecting plate all form a surface contact abutment relationship, it can effectively prevent the door side panel from deforming inward or outward when subjected to force, thereby enhancing the stability of the door side panel in the thickness direction, that is, the front and rear of the door body, and can play a stable supporting role for the entire door side panel.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the reinforcing member includes a second supporting rib, the second supporting rib being disposed on the side of the reinforcing plate away from the supporting plate, and the second supporting rib being attached to and supported on the front wall of the second connecting plate.

[0014] The above technical solution has the following advantages or beneficial effects: By providing a second supporting rib on the side of the reinforcing plate away from the supporting plate, the second supporting rib can be a raised rib structure, which provides support and reinforcement for the entire reinforcing member. Specifically, the second supporting rib is fitted to the back of the second connecting plate, thereby increasing the contact area between the reinforcing member and the second connecting plate. When one side of the handle groove is subjected to force, the force on the side wall of the handle groove can be transmitted to the second supporting rib through the reinforcing plate, and the stress can be further dispersed by the second supporting rib. This can more effectively avoid excessive local stress, and at the same time, it can provide better support for the door side panel, thereby improving the overall structural strength of the door.

[0015] In some embodiments of this application, a refrigeration device is provided. The door side panel includes a first handle plate, one side of which is connected to the outer side of a first connecting plate, and the other side of which extends obliquely toward the inner side of the door body. A second handle plate is disposed on the side of the first handle plate away from the door panel, one side of which is bent and connected to the inner side of the first handle plate, and the other side of which extends obliquely toward the outer side of the door body. A handle groove is formed between the outer sidewall of the second handle plate and the first handle plate. A reinforcing plate is attached to the inner sidewall of the second handle plate.

[0016] The above technical solution has the following advantages or beneficial effects: By attaching a reinforcing plate to the inner wall of the second handle plate, and since the reinforcing plate is attached to the back of the second handle plate, a composite structural layer can be formed with the second handle plate. This effectively alleviates and disperses stress concentration, preventing localized dents or other door deformations in the handle groove area due to uneven stress.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein the door side panel further includes an extension plate, which is bent and extended rearward from the outer side of the first connecting plate, and the extension plate is connected between the first connecting plate and the first handle plate; the door frame further includes a reinforcing rib, which is disposed on the inner side wall of the extension plate, and the front and rear sides of the reinforcing rib are respectively connected to the first connecting plate and the first handle plate.

[0018] The above technical solution has the following advantages or beneficial effects: Reinforcing ribs are provided on the inner wall of the extension plate, arranged along the length of the extension plate. The front end of the reinforcing rib connects to the first connecting plate, and the rear end connects to the first handle plate, allowing the reinforcing ribs to simultaneously support both the extension plate and the first handle plate. Specifically, when the door is subjected to repeated tension or impact during opening or closing, the external force can be transmitted from the first handle plate to the first connecting plate. The reinforcing ribs, as an intermediate support structure, can share some of the transmitted load, reducing the risk of deformation caused by direct stress on the first connecting plate and the first handle plate. Furthermore, the reinforcing ribs also help improve the surface stability of the extension plate itself, preventing warping or bulging deformations under stress.

[0019] In some embodiments of this application, a cooling device is provided, wherein at least a portion of the support plate abuts against the side of the reinforcing rib away from the extension plate.

[0020] The above technical solution has the following advantages or beneficial effects: by abutting at least a portion of the support plate against the side of the reinforcing rib away from the extension plate, the supporting effect of the reinforcing member on the door side panel is strengthened. Specifically, when the handle groove area is pulled by the user or impacted by other external forces, the force is transmitted to the reinforcing member through the door side panel, and the support plate in the reinforcing member will bear and transmit part of the load. Since the support plate abuts against the reinforcing rib, a stable supporting structure for the first handle plate can be formed, effectively limiting the deformation of the support plate under force, thereby improving the overall stability and torsional rigidity of the door structure.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein the support plate is provided with an insertion hole; the door frame further includes a snap fastener, which is disposed on the inner wall of the door side panel and between the first handle plate and the second handle plate; the snap fastener is arranged opposite to the insertion hole, and the snap fastener can be inserted into the insertion hole and engaged with the peripheral edge of the insertion hole, so that the reinforcing member is fixed on the inner wall of the door side panel.

[0022] The above technical solution has the following advantages or beneficial effects: by setting insertion holes on the support plate and setting spring buckles on the inner wall of the door side panel at the position corresponding to the position between the first handle plate and the second handle plate, a quick snap-fit ​​structure between the reinforcing member and the door side panel is formed, realizing reliable fixing and convenient installation of the reinforcing member.

[0023] In some embodiments of this application, a cooling device is provided, wherein a flange is provided on the peripheral edge of the socket near the door panel, and the flange extends toward the inner side of the door body; the snap fastener includes an extension arm, which is protrudingly provided on the inner wall of the door side panel and disposed between the first handle plate and the second handle plate; the extension arm extends toward the inside of the door body, the extension arm passes through the socket, and the extension arm is attached to and abuts against the back of the flange; a hook is provided at one end of the extension arm near the inside of the door body, and the hook engages with one end of the flange away from the door side panel.

[0024] The above technical solution has the following advantages or beneficial effects: The extension arm protrudes from the inner wall of the door side panel toward the inner side of the door, passes through the insertion hole and abuts against the back of the flange, thereby clamping the reinforcing support plate between the door side panel and the spring clip. Thus, the section of the extension arm away from the inner wall of the door side panel forms a suspended end, and the hook is correspondingly set on the suspended end, allowing the spring clip to have a certain elastic deformation capability. This not only improves the smoothness of installation during the alignment and engagement process of the spring clip and the reinforcing plate, but also allows the spring clip to apply a greater engaging force to the reinforcing member after it is installed on the inner wall of the door side panel, enabling the irregularly shaped reinforcing member to be more stably and reliably fixed to the inner side of the door side panel.

[0025] In some embodiments of this application, a refrigeration device is provided, wherein the door frame further includes a support arm, the support arm is disposed on the inner side of the first connecting plate and extends from the first connecting plate toward the inner side of the door body; the support arm is attached to the back of the door panel; the support arm is located on the side of the first support rib away from the door side panel.

[0026] The above technical solution has the following advantages or beneficial effects: By arranging a support arm extending from the first connecting plate toward the inside of the door, the support arm can be a rib-like structure formed by the protrusion of the support plate surface, which is attached to the back of the first connecting plate. When the reinforcing member is inserted into the door body at an inclined angle, the side of the reinforcing member facing the door panel first contacts or abuts against the support arm. In this way, even if the reinforcing member shakes or misaligns slightly during the insertion of the reinforcing member into the inner wall of the door side panel or during the straightening process, the support arm can support the side of the reinforcing member close to the door panel, thereby preventing direct contact between the reinforcing member and the door panel and thus preventing scratches and indentations on the back of the door panel.

[0047] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0048] Figure 1This is a schematic diagram of a refrigeration device according to an embodiment of this application; Figure 2 for Figure 1 A partial schematic diagram. It should be noted that... Figure 2 for Figure 1 A diagram showing the hidden upper door.

[0049] like Figure 1 As shown, the refrigerator provided in this embodiment of the present invention includes a cabinet 1. The cabinet 1 can adopt a hollow structure such as a cuboid. The cabinet 1 forms the outer shell of the refrigerator. It should be noted that the cabinet 1 can also adopt a hollow shell structure of other shapes.

[0050] like Figure 2 As shown, in some embodiments, the interior of the housing 1 forms a refrigeration chamber 101 with a front opening. Multiple refrigeration chambers 101 may be provided.

[0051] 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.

[0052] like Figure 2 As shown, in some embodiments, the refrigerator may include shelves 11. Multiple shelves 11 may be provided, and multiple shelves 11 are provided in the refrigeration compartment 101, thereby dividing the interior of the refrigeration compartment 101 into multiple storage spaces. The top surface of the shelves 11 can provide a support surface for items to be refrigerated.

[0053] In some embodiments, the refrigerator may include a refrigerator liner (not shown in the figure). The refrigerator liner may be disposed inside the refrigerator body 1. A refrigeration compartment 101 may be provided inside the refrigerator liner.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the refrigerator includes a door 2. The door 2 is disposed on the front side of the cabinet 1 and covers the opening of the refrigeration compartment 101 for opening and closing the refrigeration compartment 101.

[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] The refrigerator includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the refrigerator body 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 101.

[0057] In some embodiments, the refrigeration system includes 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.

[0058] In some embodiments, the refrigeration system includes a condenser (not shown). The condenser can be used to receive refrigerant flowing out of the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0059] In some embodiments, the refrigeration system includes a throttling device (not shown). The condenser can deliver the 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.

[0060] In some embodiments, the refrigeration system includes an evaporator (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator. The evaporator can be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0061] 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.

[0062] Figure 3 for Figure 1 A schematic diagram of the back of the central door; Figure 4 for Figure 3 An exploded image.

[0063] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the door 2 may include a door panel 21. The door panel 21 is located on the front side of the door 2, thereby blocking the opening of the refrigeration compartment 101.

[0064] like Figure 3 and Figure 4 As shown, in some embodiments, the door body 2 may include a door frame 22. The door frame 22 is located on the back side of the door panel 21. The door frame 22 may be arranged along the peripheral edge of the back side of the door panel 21. It should be noted that when the door body 2 is closed in the opening of the refrigeration compartment 101, the side of the door panel 21 away from the refrigeration compartment 101 is the front side of the door panel 21, and the side of the door panel 21 facing the refrigeration compartment 101 is also the front side of the door panel 21. The door frame 22 can serve as a supporting structure for the door body 2, forming the overall frame of the door body 2 together with the door panel 21, thereby improving the stability and reliability of the door body 2 structure.

[0065] like Figure 4 As shown, in some embodiments, the door frame 22 can be a U-shaped structure. One side of the door frame 22 can be hinged to the housing 1, so that the door 2 can be hinged to the housing 1, and the refrigeration compartment 101 can be opened or closed by rotating the door 2.

[0066] Figure 5 for Figure 3 A schematic diagram of the middle door frame; Figure 6 for Figure 5 A schematic diagram from another perspective.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments, the door frame 22 may include a door side panel 221. The door side panel 221 is disposed on the side of the door frame 22 away from its hinge to the housing. The door side panel 221 is disposed on the peripheral edge of the back side of the door panel 21. The door side panel 221 is recessed inward toward the door body 2 with a handle groove 201. The handle groove 201 is disposed opposite to the side of the door frame that is hinged to the housing.

[0068] The door side panel 221, as part of the door frame 22, is located on the back edge of the door panel 21, providing support and fixation for the door panel 21. The handle groove 201 recessed on the inner side of the door side panel 221 facing the door body 2 provides a convenient handle structure for users and avoids the stress concentration problem at the connection between the handle and the door frame 22 caused by traditional separate handles, thus improving the structural strength and durability of the door body 2.

[0069] In some embodiments, the door frame 22 may include a first connecting plate 222. The first connecting plate 222 extends from the side of the door side panel 221 near the door panel 21 toward the inside of the door body 2. The first connecting plate 222 is attached to the back of the door panel 21. The first connecting plate 222 is tightly attached to the back of the door panel 21, which can enhance the connection strength between the door panel 21 and the door side panel 221, making the door body 2 structure more stable.

[0070] like Figure 4 As shown, in some embodiments, the door body 2 may include a reinforcing member 23. The reinforcing member 23 is disposed on the inner wall of the door side panel 221. By providing the reinforcing member 23, the strength of the inner side of the door frame 22 can be enhanced, compensating for the structural strength reduction problem that may be caused by the recess of the door side panel 221 forming the handle groove 201.

[0071] Figure 7 for Figure 3 A cross-sectional view; Figure 8 for Figure 7 A magnified view of part A; Figure 9 for Figure 3 A schematic diagram of the central reinforcement component.

[0072] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the reinforcing member 23 may include a reinforcing plate 231. The reinforcing plate 231 is attached to the inner sidewall of the door side panel 221 opposite to the handle groove 201. That is, the reinforcing member 23 is attached to the inner sidewall of the handle groove 201. Since the reinforcing plate 231 acts directly on the relatively weak area of ​​the door side panel 221 due to the recessed handle groove 201, it can enhance the strength of the door side panel 221 in the area of ​​the handle groove 201, making the door side panel 221 less prone to deformation when subjected to external forces, thus ensuring the integrity and stability of the door body 2 structure.

[0073] like Figure 8 and Figure 9 As shown, in some embodiments, the reinforcing member 23 may include a support plate 232. The support plate 232 extends from the reinforcing plate 231 toward the door panel 21. The side of the support plate 232 near the door panel 21 abuts against the back of the first connecting plate 222. Thus, when the door body 2 is subjected to external force, the force on the side wall of the handle groove 201 can be transmitted to the support plate 232 through the reinforcing plate 231, and the stress can be dispersed to other parts of the door body 2, such as the first connecting plate 222 and the door panel 21, through the support plate 232. This can avoid excessive local stress and further improve the overall strength and deformation resistance of the door body 2. Moreover, since the support plate 232 abuts against the first connecting plate 222, it can avoid directly acting on the inner side of the door panel 21, thereby preventing friction and scratches on the inner side of the door panel 21 and affecting the appearance of the door body 2.

[0074] Currently, the design of recessing the door handle on the door frame 22 can effectively prevent stress concentration at the connection between the handle and the door frame 22 caused by the split handle. However, after the door handle is formed by recessing the door frame 22, the recessed area of ​​the door frame 22 is relatively weak compared to other areas. Its structural strength is insufficient and it is easy to cause stress concentration, which in turn causes deformation during the foaming and molding of the door body 2, affecting the sealing performance. In addition, in daily use, the insufficient structural strength of the recessed area of ​​the door frame 22 is also prone to deformation.

[0075] In this application, a reinforcing member 23 is provided on the inner wall of the door side panel 221. The reinforcing member 23 includes a reinforcing plate 231 and a supporting plate 232. The reinforcing plate 231 is attached to the inner wall of the door side panel 221 opposite to the handle groove 201, which can directly enhance the structural strength of the handle groove 201 of the door side panel 221 and improve the deformation resistance of the handle groove 201 of the door side panel 221. The supporting plate 232 extends from the reinforcing plate 231 toward the door panel 21, and the side of the supporting plate 232 near the door panel 21 abuts against the back of the first connecting plate 222. This means that the reinforcing member 23 not only provides support in the thickness direction of the door side panel 221, but also forms a support structure in the front-rear direction of the door body 2. Specifically, when the door body 2 is subjected to external force, the force on the side wall of the handle groove 201 can be transmitted to the support plate 232 through the reinforcing plate 231. Since the support plate 232 can abut against the first connecting plate 222, the external force can be distributed to other parts of the door body 2, avoiding excessive local stress and effectively improving the overall strength of the door body 2.

[0076] like Figure 8 and Figure 9 As shown, in some embodiments, the reinforcing member 23 may include a first support rib 233. The first support rib 233 is disposed on the side of the support plate 232 near the first connecting plate 222. The first support rib 233 is attached to and supported on the back of the first connecting plate 222.

[0077] Specifically, a first supporting rib 233 is provided on the side of the support plate 232 near the first connecting plate 222. The first supporting rib 233 can be a raised rib structure, which provides support and reinforcement for the entire reinforcing member 23. Specifically, the first supporting rib 233 is attached to the back of the first connecting plate 222, thereby increasing the contact area between the reinforcing member 23 and the first connecting plate 222. When one side of the handle groove 201 is subjected to force, the force on the side wall of the handle groove 201 can be transmitted to the support plate 232 through the reinforcing plate 231, and the stress can be further dispersed by the first supporting rib 233. This can more effectively avoid excessive local stress, and at the same time, it can provide better support for the door side panel 221, thereby improving the overall structural strength of the door body 2.

[0078] Specifically, the first support rib 233 can extend along the length of the support plate 232 and be attached to the back of the first connecting plate 222.

[0079] like Figure 9 As shown, in some embodiments, the first support rib 233 may extend from the support plate 232 toward the inner side of the door body 2. It should be noted that in other embodiments, the first support rib 233 may extend from the support plate 232 toward the door side panel 221.

[0080] like Figure 7 and Figure 8 As shown, in some embodiments, the door body 2 may include a door insert 24. The door insert 24 is disposed on the side of the door frame 22 away from the door panel 21. The door insert 24 may be disposed at intervals on the back side of the door panel 21. The door insert 24, the door panel 21, and the door frame 22 can enclose and form a foaming space in the door body 2. When the foaming material is filled in this space, it can effectively provide insulation for the cooling chamber 101.

[0081] like Figure 7 and Figure 8 As shown, in some embodiments, the door frame 22 may include a second connecting plate 223. The second connecting plate 223 is disposed on the side of the door side panel 221 away from the first connecting plate 222. The second connecting plates 223 are arranged at intervals on the back side of the first connecting plate 222. The peripheral edge of the door liner 24 is connected to the back side of the second connecting plate 223.

[0082] The reinforcing member 23 is disposed between the first connecting plate 222 and the second connecting plate 223. The side of the supporting plate 232 away from the reinforcing plate 231 abuts against the rear wall of the first connecting plate 222. The side of the reinforcing plate 231 away from the supporting plate 232 abuts against the front wall of the second connecting plate 223.

[0083] In this design, the reinforcing member 23 is positioned between the first connecting plate 222 and the second connecting plate 223. The front end of the reinforcing member 23 abuts against the first connecting plate 222 via a support plate 232, and the rear end of the reinforcing member 23 abuts against the second connecting plate 223 via a reinforcing plate 231, thus forming a multi-point support structure for the door side panel 221. This not only allows the reinforcing member 23 to bear and distribute the force on the door panel 21 and the handle area, but also provides direct and effective support to the door side panel 221 itself.

[0084] Specifically, the door side panel 221 is in a relatively weak position in the door body 2 structure. Especially during the operation of the handle, the door side panel 221 around the handle groove 201 is easily subjected to concentrated stress, which may lead to deformation or even cracking. The setting of the reinforcing member 23 can make the space between the first connecting plate 222 and the second connecting plate 223 have a higher resistance to deformation. When the user pulls or pushes the handle groove 201, the external force will first act on the handle groove 201 area of ​​the door side panel 221. At this time, the reinforcing plate 231 is in contact with the inner wall of the door side panel 221 and can directly share part of the load. Furthermore, the support plate 232 extends the force path to the first connecting plate 222, and the reinforcing plate 231 guides the force to the second connecting plate 223. Furthermore, since the support plate 232 and the first connecting plate 222, and the reinforcing plate 231 and the second connecting plate 223, are in surface contact with each other, the door side panel 221 can be effectively prevented from deforming inward or outward under force, thereby enhancing the stability of the door side panel 221 in the thickness direction, that is, in the front and rear direction of the door body 2. The reinforcing member 23, in conjunction with the structural arrangement of the door side panel 221, can provide stable support for the entire door side panel 221.

[0085] like Figure 8 and Figure 9 As shown, in some embodiments, the reinforcing member 23 may include a second support rib 234. The second support rib 234 is disposed on the side of the reinforcing plate 231 away from the supporting plate 232. The second support rib 234 is attached to and supported on the front wall of the second connecting plate 223.

[0086] Specifically, a second supporting rib 234 is provided on the side of the reinforcing plate 231 away from the supporting plate 232. The second supporting rib 234 can be a raised rib structure, which provides support and reinforcement for the reinforcing member 23 as a whole. Specifically, the second supporting rib 234 is attached to the back of the second connecting plate 223, thereby increasing the contact area between the reinforcing member 23 and the second connecting plate 223. When one side of the handle groove 201 is subjected to force, the force on the side wall of the handle groove 201 can also be transmitted to the second supporting rib 234 through the reinforcing plate 231, and the stress can be further dispersed by the second supporting rib 234. This can more effectively avoid excessive local stress, and at the same time, it can provide better support for the door side panel 221, thereby improving the overall structural strength of the door body 2.

[0087] Specifically, the second support rib 234 can extend along the length of the support plate 232 and be attached to the back of the second connecting plate 223.

[0088] like Figure 9 As shown, in some embodiments, the first support rib 233 and the second support rib 234 can both extend toward the door side of the door body 2.

[0089] In some embodiments, the door side panel 221 may include a first handle plate 2211 and a second handle plate 2212. One side of the first handle plate 2211 is connected to the outer side of the first connecting plate 222. The other side of the first handle plate 2211 extends obliquely toward the inner side of the door body 2. The second handle plate 2212 is disposed on the side of the first handle plate 2211 away from the door panel 21. One side of the second handle plate 2212 is bent and connected to the inner side of the first handle plate 2211. The other side of the second handle plate 2212 extends obliquely toward the outer side of the door body 2. A handle groove 201 is formed between the outer sidewall of the second handle plate 2212 and the first handle plate 2211. A reinforcing plate 231 is attached to the inner sidewall of the second handle plate 2212.

[0090] The door side panel 221 is formed by the first handle plate 2211 and the second handle plate 2212 to form a handle groove 201. By extending the inner side of the first handle plate 2211 towards the inner side of the door body 2 and extending the second handle plate 2212 towards the outer side of the door body 2 from the inner side of the first handle plate 2211, a handle shape with smooth lines is formed, thereby providing a force point for the user to pull the door body 2.

[0091] Furthermore, a reinforcing plate 231 is attached to the inner wall of the second handle plate 2212. Since the reinforcing plate 231 is attached to the back of the second handle plate 2212, it can form a composite structural layer with the second handle plate 2212. Specifically, during use, when the pulling force applied by the user's hand is transmitted to the outer wall of the second handle plate 2212, the external force can be transmitted along the plate to its inner wall and distributed to the entire reinforcing member 23 and other parts of the door body 2 through the reinforcing plate 231. This provides direct load-bearing support for the second handle plate 2212 and enhances the bending stiffness and compressive strength of the entire handle groove 201 area. In this way, stress concentration can be effectively alleviated and dispersed, avoiding problems such as local dents or other door body 2 deformations in the handle groove 201 area due to uneven stress.

[0092] like Figure 9 As shown, in some embodiments, the support plate 232 can extend along the front-rear direction of the door body 2. The side of the support plate 232 away from the door panel 21 is bent towards the outside of the door body 2 to form a reinforcing plate 231, and the reinforcing plate 231 extends obliquely on the side away from the door panel 21. In this way, the reinforcing plate 231 can be arranged parallel to and opposite to the second handle plate 2212 to fit against the inner wall of the second handle plate 2212.

[0093] In some other embodiments, the reinforcing plate 231 may be attached to the first handle plate 2211.

[0094] like Figure 9As shown, in some embodiments, the door side panel 221 may include an extension plate 2213. The extension plate 2213 extends rearward from the outer side of the first connecting plate 222. The extension plate 2213 connects the first connecting plate 222 and the first handle plate 2211. The extension direction of the extension plate 2213 may be along the thickness direction of the door frame 22, that is, the front-rear direction of the refrigeration device.

[0095] An extension plate 2213 is provided between the first connecting plate 222 and the first handle plate 2211 on the door side panel 221, forming a connecting transition structure between the two. In this way, the handle groove 201 can have a certain extension distance on the side closer to the door panel 21, making it convenient for the user to apply force to the handle groove 201 and use it.

[0096] like Figure 6 and Figure 9 As shown, the door frame 22 may include a reinforcing rib 224. The reinforcing rib 224 is disposed on the inner side wall of the extension plate 2213. The front and rear sides of the reinforcing rib 224 are respectively connected to the first connecting plate 222 and the first handle plate 2211.

[0097] Reinforcing ribs 224 are provided on the inner wall of the extension plate 2213. These ribs are arranged along the length of the extension plate 2213, with their front ends connected to the first connecting plate 222 and their rear ends connected to the first handle plate 2211. This allows the reinforcing ribs 224 to simultaneously support both the extension plate 2213 and the first handle plate 2211. Specifically, when the door 2 is subjected to repeated tension or impact during opening or closing, the external force can be transmitted from the first handle plate 2211 to the first connecting plate 222. The reinforcing ribs 224, as an intermediate support structure, can share some of the transmitted load, reducing the risk of deformation caused by direct stress on the first connecting plate 222 and the first handle plate 2211. Furthermore, the reinforcing ribs 224 also help improve the surface stability of the extension plate 2213 itself, preventing warping or bulging under stress.

[0098] like Figure 6 As shown, in some embodiments, multiple reinforcing ribs 224 may be provided, and the multiple reinforcing ribs 224 may be arranged at intervals along the length direction of the extension plate 2213.

[0099] In some embodiments, the first connecting plate 222, the extension plate 2213, the first handle plate 2211, the second handle plate 2212 and the second connecting plate 223 in the door side panel 221 can be integrally stamped.

[0100] like Figure 6 and Figure 8 As shown, in some embodiments, at least a portion of the support plate 232 may abut against the side of the reinforcing rib 224 away from the extension plate 2213.

[0101] The reinforcing rib 224, on the side away from the extension plate 2213, can extend towards the inside of the door body 2. When the reinforcing member 23 is located inside the door side panel 221, at least a portion of the supporting plate 232 abuts against the side of the reinforcing rib 224 away from the extension plate 2213, thereby strengthening the supporting effect of the reinforcing member 23 on the door side panel 221. Specifically, when the handle groove 201 area is pulled by the user or impacted by other external forces, the force will be transmitted to the reinforcing member 23 through the door side panel 221, and the supporting plate 232 in the reinforcing member 23 will bear and transmit part of the load. Since the supporting plate 232 abuts against the reinforcing rib 224, a stable supporting structure for the first handle plate 2211 can be formed, effectively limiting the deformation of the supporting plate 232 under force, thereby improving the overall stability and torsional resistance of the door body 2 structure.

[0102] Figure 10 for Figure 6 A cross-sectional schematic diagram.

[0103] like Figure 9 and Figure 10 As shown, in some embodiments, the support plate 232 may be provided with an insertion hole 202. The door frame 22 may include a spring clip 25. The spring clip 25 is provided on the inner wall of the door side plate 221 and is located between the first handle plate 2211 and the second handle plate 2212. The spring clip 25 is arranged opposite to the insertion hole 202, and the spring clip 25 can be inserted into the insertion hole 202 and engage with the peripheral edge of the insertion hole 202, so that the reinforcing member 23 is fixed to the inner wall of the door side plate 221.

[0104] In this embodiment, by providing an insertion hole 202 on the support plate 232 and a snap-fit ​​25 on the inner wall of the door side plate 221 at the position between the first handle plate 2211 and the second handle plate 2212, a quick-connect structure between the reinforcing member 23 and the door side plate 221 is formed, thereby achieving reliable fixation and convenient installation of the reinforcing member 23.

[0105] Specifically, the spring clip 25 is a snap-fit ​​structure with a certain elastic deformation capability, which naturally protrudes outward or is positioned at the corresponding position of the insertion hole 202 when not under force. When the reinforcing member 23 is assembled on the inner wall of the door side panel 221, the insertion hole 202 on the support plate 232 is aligned with the position of the spring clip 25. When a slight pressure is applied towards the door side panel 221, the spring clip 25 can elastically insert into the insertion hole 202 and form a snap-fit ​​with its surrounding structure, thereby firmly positioning the reinforcing member 23 in the inner wall area of ​​the door side panel 221.

[0106] like Figure 6As shown, in some embodiments, multiple spring clips 25 may be provided. Multiple spring clips 25 may be spaced apart along the length of the door side panel 221. Correspondingly, the support plate 232 is provided with multiple insertion holes 202 arranged opposite to the spring clips 25. This further improves the connection strength between the reinforcing member 23 and the inner wall of the door side panel 221, allowing the reinforcing member 23 to be stably supported on the inner wall of the handle groove 201.

[0107] like Figure 8 and Figure 9 As shown, in some embodiments, the peripheral edge of the socket 202 near the door panel 21 may be provided with a flange 235. The flange 235 extends toward the inside of the door body 2.

[0108] Specifically, the flange 235 serves as a protruding sidewall extending from the edge of the insertion hole 202 toward the door side of the door body 2. Thus, the flange 235 can extend toward the inside of the door body 2 to form a stepped limiting structure. In some specific embodiments, the flange 235 can be stamped from the reinforcing member 23.

[0109] The snap-on latch 25 may include an extension arm 251 and a hook 252. The extension arm 251 is protruding from the inner wall of the door side panel 221. The extension arm 251 is located between the first handle plate 2211 and the second handle plate 2212. The extension arm 251 extends inward toward the door body 2 and passes through the insertion hole 202. The extension arm 251 is attached to and abuts against the back of the flange 235; the hook 252 is located at the end of the extension arm 251 near the inner side of the door body 2, and the hook 252 engages with the end of the flange 235 away from the door side panel 221.

[0110] The extension arm 251 protrudes from the inner wall of the door side panel 221 toward the inner side of the door body 2, passes through the insertion hole 202, and rests against the back of the flange 235, thereby clamping the reinforcing member 23 support plate 232 between the door side panel 221 and the spring buckle 25. In this way, the section of the extension arm 251 away from the inner wall of the door side panel 221 forms a suspended end, and the hook 252 is correspondingly set on the suspended end, so that the spring buckle 25 can have a certain elastic deformation capability. This not only helps to improve the smoothness of the installation process during the alignment and snapping process of the spring buckle 25 and the reinforcing plate 231, but also allows the spring buckle 25 to apply a greater snapping force to the reinforcing member 23 after it is installed on the inner wall of the door side panel 221, so that the irregularly shaped reinforcing member 23 can be more stably and reliably fixed to the inner side of the door side panel 221.

[0111] Furthermore, the front side of the flange 235 faces the back of the first connecting plate 222, and the back of the flange 235 faces the second connecting plate 223. When the reinforcing member 23 is snapped onto the door side panel 221, the extension arm 251 of the snap fastener 25 is attached to the back of the flange 235. Moreover, since the extension arm 251 is located between the first handle plate 2211 and the second handle plate 2212, it is equivalent to clamping the support plate 232 of the reinforcing member 23 between the door side panel 221 and the snap fastener 25. The contact between the door side panel 221 and the back of the flange 235 can increase the contact area between the snap fastener 25 and the flange 235, which not only plays a limiting role, but also enhances the reliability and stability of the snapping between the inner side of the door side panel 221 and the reinforcing member 23. The extension arm 251 has a hook 252 structure at its end, which engages with the end of the flange 235 away from the door side panel 221 after being inserted into the insertion hole 202, thereby achieving the final locking of the reinforcing member 23.

[0112] like Figure 6 and Figure 9 As shown, in some embodiments, the door frame 22 may include a guide post 27. The guide post 27 may be disposed on the inner wall of the door side panel 221. Correspondingly, the reinforcing member 23 may be provided with a guide hole 203, which is arranged opposite to the guide post 27. When the reinforcing member 23 is installed on the inner wall of the door side panel 221, the guide hole 203 on the reinforcing member 23 can be aligned and engaged with the guide post 27 first, thereby pre-positioning the position of the reinforcing member 23, and then the reinforcing member 23 can be engaged with the spring buckle 25 by adjusting the angle of the reinforcing member 23, etc.

[0113] like Figure 6 and Figure 10 As shown, in some embodiments, the door frame 22 may include a support arm 26. The support arm 26 is disposed on the inner side of the first connecting plate 222 and extends from the first connecting plate 222 toward the inner side of the door body 2. The support arm 26 may be attached to the back of the door panel 21. The support arm 26 is located on the side of the first support rib 233 away from the door side panel 221.

[0114] Because the space for installing the reinforcing member 23 on the door side panel 221 is limited, during actual installation, the reinforcing member 23 needs to be inserted into the limited space between the door side panel 221 and the door panel 21 at a certain angle, and then rotated to a fitted state to achieve accurate positioning and fixation. In this process, the reinforcing member 23 may come into contact with and rub against the door panel 21, posing a risk of scratches or indentations. In particular, when the door panel 21 is made of a transparent material such as glass, scratches on the back of the door panel 21 will seriously affect the appearance of the refrigeration unit.

[0115] In this embodiment, a support arm 26 is arranged extending from the first connecting plate 222 toward the inside of the door body 2. The support arm 26 can be a rib-like structure formed by the protrusion of the support plate 232, which is attached to the back of the first connecting plate 222. When the reinforcing member 23 is inserted into the door body 2 at an inclined angle, the side of the reinforcing member 23 facing the door panel 21 first contacts or abuts against the support arm 26. In this way, even if the reinforcing member 23 shakes or misaligns slightly during the insertion into the inner wall of the door side panel 221 or during the alignment process, the support arm 26 can support the side of the reinforcing member 23 near the door panel 21, thereby preventing the reinforcing member 23 from directly contacting the door panel 21 and causing scratches or indentations on the back of the door panel 21.

[0116] like Figure 6 As shown, in some embodiments, multiple support arms 26 may be provided. Multiple support arms 26 may be arranged at intervals along the length direction of the first connecting plate 222.

[0117] In some other embodiments, the first connecting plate 222 extends toward the inside of the door body 2 with a raised edge, which is located on the side of the first support rib 233 away from the door side plate 221. Specifically, the raised edge can be a raised edge that is continuously arranged along the length of the first connecting plate 222, which can also protect the back of the door panel 21 to prevent the reinforcement 23 from scratching the back of the door panel 21 during installation.

[0118] 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.
