Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a refrigeration device. Background Technology

[0002] In related technologies, some refrigeration equipment uses a plug-in method to assemble the inner liner and the frame. Specifically, the four sides of the open side of the inner liner are directly inserted into the plug-in grooves on the back of the frame. However, in practical applications, this installation method has several drawbacks. First, the locking force provided by the simple plug-in connection is extremely limited. Under long-term impact and vibration from opening and closing the door, the inner liner and the frame are prone to relative misalignment, causing the door seal to fail directly. Some refrigeration equipment manufacturers have also attempted to fasten the inner liner and the frame by combining riveting or threaded connections. However, introducing riveting or threaded connections makes the assembly and disassembly processes of the inner liner and the frame more complex. Second, after the inner liner and the frame are plugged in, the frame protrudes inward relative to the compartment wall, forming a thick annular protrusion between the frame and the inner liner. The rear side of this annular protrusion becomes a cleaning dead zone, which accumulates dirt and grime over time, leading to bacterial growth and odor. This increases the difficulty of cleaning and seriously affects the user's experience. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a refrigeration device that enhances the bonding force between the frame and the inner liner, making the installation and disassembly of the frame relatively simple, reducing cleaning difficulty, and improving the user's experience.

[0051] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0052] This application discloses a refrigeration device 10.

[0053] It should be noted that the refrigeration equipment 10 in this embodiment includes, but is not limited to, refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines, etc. The refrigeration equipment 10 has a variety of structural forms and a wide range of applications.

[0054] The following is for reference. Figures 1-18 A refrigeration device 10 according to an embodiment of this application is described.

[0055] In some embodiments, refer to Figure 1 The refrigeration equipment 10 includes: an outer shell 11, an inner liner 12, an insulation layer, and a frame 13.

[0056] Reference Figures 1 to 3 The inner liner 12 is installed inside the outer shell 11, forming a compartment 121 open on one side. The opening of the inner liner 12 includes an assembly structure 1262, which forms a first snap-fit ​​portion 126a and an installation flare 126b facing the inside of the compartment 121. An insulation layer is formed between the outer shell 11 and the inner liner 12. A frame 13 is connected between the outer shell 11 and the inner liner 12. At least a portion of the inner side of the frame 13 is installed in the installation flare 126b. The back of the frame 13 is provided with a second snap-fit ​​portion 136 for snapping with the first snap-fit ​​portion 126a.

[0057] The inner liner 12 can be made of metal or plastic, and can be formed by processes such as stamping, extrusion or injection molding. This application embodiment does not limit this.

[0058] The mouth frame 13 is installed on the open side of the inner liner 12 via the assembly structure 1262. The mouth frame 13 can be an integral structure or a split structure, and this application does not limit it.

[0059] As an example, the frame 13 adopts a split design. Specifically, the frame 13 may include multiple inserts and multiple side beams that are welded together. Each insert is connected to two side beams, and the two ends of each side beam are connected to two inserts respectively. The multiple side beams are spliced ​​together end to end to form a frame shape.

[0060] The first snap-fit ​​part 126a may include, but is not limited to, a snap fastener, a snap tooth, a snap hook, a snap claw, a snap groove, or a through hole. Correspondingly, the second snap-fit ​​structure may include, but is not limited to, a snap fastener, a snap tooth, a snap hook, a snap claw, a snap groove, or a through hole that cooperates with the first snap-fit ​​structure. The embodiments of this application do not limit this.

[0061] In this embodiment, the dimensions of the inner circumference of the mouth frame 13 are designed to match the dimensions of the mounting flare 126b. During production, a second snap-fit ​​portion 136 is integrally formed on the back of the mouth frame 13 to match the first snap-fit ​​portion 126a of the inner liner 12. The manufactured mouth frame 13 is then installed between the outer shell 11 and the inner liner 12. Specifically, refer to... Figure 2 Align the opening frame 13 with the assembly structure 1262 at the opening of the inner liner 12, and press the opening frame 13 firmly to lock the second locking part 136 into the first locking part 126a. Simultaneously, most of the inner side of the opening frame 13 will be embedded into the mounting flare 126b. After installation, refer to... Figure 3 The inner side of the frame 13 is recessed into the mounting flare 126b, with only a slight bulge at the edge of the mounting flare 126b, forming a smoother transition arc surface. This avoids the thicker annular protrusion produced by traditional plug-in methods, greatly reducing the height difference between the inner wall of the frame 13 and the side wall of the compartment 121, thereby reducing cleaning dead corners. In addition, the snap-fit ​​area is hidden on the back of the frame 13, making the appearance of the refrigeration equipment 10 more flat and aesthetically pleasing, without obvious protrusions or depressions, improving the overall appearance quality of the product.

[0062] In other embodiments, the inner sidewall of the frame 13 can also be integrally embedded with the flared opening 126b; in other words, the inner sidewall of the frame 13 is flush with the sidewall of the compartment 121. In this case, it may be necessary to machine the edges where the flared opening 126b is installed and the ends of the inner sidewall of the frame 13 at right angles, or to use some sealing treatments to achieve seamlessness at the joint as much as possible.

[0063] The refrigeration device 10 provided in this application embodiment achieves a stable and reliable assembly between the door frame 13 and the inner liner 12 through the snap-fit ​​cooperation of the first snap-fit ​​part 126a and the second snap-fit ​​part 136. This enhances the bonding force between the door frame 13 and the inner liner 12, reduces the probability of loosening between the inner liner 12 and the door frame 13 under long-term use, thereby maintaining the long-term reliability of the door seal, reducing cold air leakage, and thus reducing the energy consumption of the refrigeration device 10. At the same time, it simplifies the installation and disassembly process of the door frame 13, eliminating the need for complex riveting or screwing. The textured connection operation not only improves processing efficiency but also reduces maintenance costs and increases maintenance efficiency. Combined with the structural design of at least part of the inner side of the frame 13 being recessed to install the flared opening 126b, the inner side wall of the frame 13 and the wall of the compartment 121 are made to transition as smoothly as possible, reducing cleaning dead corners and the risk of dirt and grime accumulating at the junction of the inner side of the frame 13 and the inner liner 12. This reduces the possibility of bacterial and odor growth, thereby reducing cleaning difficulty and helping to maintain the hygiene and cleanliness of the compartment 121, thus improving the user's sense of use and experience.

[0064] In some embodiments, refer to Figure 2 and Figure 3The assembly structure 1262 includes a first section 12621 to a third section 12623 that are bent and connected in sequence. The first section 12621 and the third section 12623 are located on both sides of the second section 12622, respectively. The first section 12621 and the second section 12622 form an installation flare 126b, and the angle between the third section 12623 and the second section 12622 is an acute angle to form a first snap-fit ​​portion 126a.

[0065] In actual implementation, taking the inner liner 12 as an example of being made of metal, the metal sheet is processed through sheet metal processes such as stamping and bending. The opening of the inner liner 12 is continuously bent three times according to the design requirements. During the bending process, the dimensions of each section and the included angle between adjacent sections are precisely controlled to meet the precision and quality requirements of the assembly structure 1262. Thus, the first section 12621 to the third section 12623, which are bent and connected in sequence, constitute the assembly structure 1262.

[0066] Among them, reference Figure 2 and Figure 3 The first segment 12621 folds outward relative to the main body of the inner liner 12, the second segment 12622 folds forward relative to the first segment 12621, and the third segment 12623 folds outward and backward relative to the second segment 12622. Thus, the first segment 12621 and the second segment 12622 together form an annular mounting flare 126b, while the second segment 12622 and the third segment 12623, which are connected at an acute angle, form a hook shape in cross-section to constitute the first snap-fit ​​portion 126a.

[0067] The refrigeration device 10 provided in this application embodiment, by designing the assembly structure 1262 as a structure in which the first segment 12621, the second segment 12622 and the third segment 12623 are sequentially bent and connected, and the third segment 12623 and the second segment 12622 form an acute angle as the first snap-fit ​​part 126a, so that the first snap-fit ​​part 126a has good guiding and self-locking properties. During installation, the acute angle structure of the first snap-fit ​​part 126a can guide the second snap-fit ​​part 136 to smoothly enter the snap-fit ​​position. After snap-fit, the wedge force generated by the acute angle structure can make the snap-fit ​​tighter, enhance the reliability and stability of the snap-fit, further improve the firmness of the connection between the inner liner 12 and the frame 13, and improve the overall structural strength of the refrigeration device 10. The structural design of the mounting flare 126b formed by combining the first segment 12621 and the second segment 12622 provides a stable and precise installation space for the inner side of the frame 13. This allows the frame 13 to maintain a good fit and consistency with the inner liner 12 after being embedded in the mounting flare 126b, thereby helping to reduce the shaking and loosening of the frame 13 during use. At the same time, the first snap-fit ​​part 126a and the mounting flare 126b are formed by only using a three-segment bending design, which improves the integration and compactness of the assembly structure 1262, thereby improving the volume utilization rate of the entire refrigeration equipment 10.

[0068] In some embodiments, refer to Figure 2 and Figure 3 The inner side of the frame 13 is press-fitted with the mounting flare 126b. The second snap-fit ​​part 136 includes a hook with the hook body facing the inner side of the frame. The end of the third segment 12623 that is away from the second segment 12622 snaps with the hook body of the second snap-fit ​​part 136.

[0069] In actual implementation, refer to Figure 2 and Figure 3During the assembly process of the frame 13 and the inner liner 12, in order to ensure that the inner side of the frame 13 can be stably embedded into the annular mounting flare 126b at the opening of the inner liner 12, the size of the inner side of the frame 13 needs to be slightly larger than the size of the mounting flare 126b in its natural state. Thus, when the inner side of the frame 13 is gradually inserted into the annular mounting flare 126b at the opening of the inner liner 12, a certain pressing force needs to be applied to the frame 13 to overcome the friction between the inner side of the frame 13 and the assembly structure 1262. The second segment 12622 is subjected to the pressure from the inner side of the frame 13... After being squeezed by the side, it deforms outward. The tail of the second segment 12622 rotates outward around the connection point between the first segment 12621 and the second segment 12622, thereby driving the third segment 12623 at the tail to press further against the hook of the second locking part 136. That is, it drives the end of the third segment 12623 away from the second segment 12622 to move further outward and backward. In this way, by utilizing the interference fit between the inner side of the frame 13 and the mounting flare 126b of the inner liner 12, the hook of the first locking part 126a and the hook of the second locking part 136 are driven to further engage and lock.

[0070] The refrigeration device 10 provided in this application embodiment, by setting the second snap-fit ​​part 136 as a snap hook with the hook body facing the inner side and cooperating with the end of the third segment 12623 away from the second segment 12622, during the assembly process, as the inner side of the frame 13 is inserted into the mounting flare 126b, the deformation of the second segment 12622 causes the third segment 12623 to actively press against the snap hook, driving the end of the third segment 12623 away from the second segment 12622 to further hook and lock with the hook body of the second snap-fit ​​part 136, thereby realizing the conversion of the interference between the inner side of the frame 13 and the mounting flare 126b into the retaining force of the snap-fit, so that the snap-fit ​​part can generate greater friction and self-locking force when subjected to external force, greatly improving the reliability and stability of the snap-fit, and thus enhancing the overall structural stability of the refrigeration device 10. In addition, the end of the third segment 12623 that is away from the second segment 12622 is pressed against the hook of the second snap-fit ​​part 136 to form a sealed fit, thereby reducing the risk of insulation material overflowing from the joint between the inner liner 12 and the mouth frame 13 during the foaming process.

[0071] In some embodiments, refer to Figure 2 and Figure 3 The connection between the first segment 12621 and the second segment 12622 forms a first chamfer 12624 with an arc angle of α1, and the inner side of the frame 13 forms a second chamfer 137 with an arc angle of α2 and opposite to the first chamfer 12624, wherein α1 < α2.

[0072] Understandably, referring to Figure 2 and Figure 3Both the first chamfer 12624 and the second chamfer 137 are radius (R-angle). Based on α1 < α2, in other words, the curvature of the first chamfer 12624 is greater than that of the second chamfer 137, meaning the curvature of the first chamfer 12624 is greater than that of the second chamfer 137. This design greatly improves assembly flexibility. In actual production, due to factors such as machining accuracy and assembly operations, certain errors inevitably exist between components. The larger α2 allows the frame 13 to have a higher tolerance for positional and angular errors when it mates with the flared end 126b of the inner liner 12. Even if the insertion direction of the frame 13 is slightly off, or the angle with the flared end 126b is not perfectly aligned, it can still be smoothly inserted thanks to the larger chamfer radius, without repeated adjustments or reassembly. This reduces assembly difficulty, improves assembly efficiency, and reduces scrap and rework caused by assembly difficulties, thereby lowering production costs.

[0073] When disassembling the frame 13, the first chamfer 12624 and the second chamfer 137 are spaced apart due to their different arc angles. While maintaining the necessary fit, this results in a relatively small contact area between the inner side of the frame 13 and the first segment 12621 and the second segment 12622. Consequently, the frictional constraint force is reduced, decreasing the probability of jamming due to excessive coupling between the corner areas of the inner side of the frame 13 and the corner areas of the flared opening 126b. This makes the disassembly process easier and more convenient. Maintenance personnel can quickly separate the frame 13 and the inner liner 12 without using complex tools or applying excessive force, shortening maintenance time, reducing maintenance difficulty, improving equipment maintainability, and reducing the risk of damage to components due to improper disassembly.

[0074] In some embodiments, refer to Figure 3 The refrigeration equipment 10 also includes: light strip 198.

[0075] The inner side of the frame 13 forms a receiving cavity 1381 for accommodating the light strip 198. The inner side of the frame 13 away from the chamber 121 is provided with an assembly opening 1382 that communicates with the receiving cavity 1381. The inner side of the frame 13 near the chamber 121 is provided with a light-transmitting window 1383 in the area opposite to the receiving cavity 1381.

[0076] Based on the internal space size and lighting requirements of the refrigeration equipment 10, a suitable light strip 198 of appropriate specifications and length, such as an LED light strip 198, may be selected. This application does not impose any restrictions on this.

[0077] The light-transmitting window 1383 can be made and installed using transparent materials such as glass or plastic. If glass is used, the glass plate needs to be cut into a suitable shape and size, the window needs to be opened at the corresponding position in the frame 13, and it needs to be installed at the window opening by means of adhesive bonding or clip fixing. If plastic is used, it can be directly integrated with the frame 13 through injection molding, which improves production efficiency and structural stability.

[0078] The light strip 198 can be set to one or more, where multiple means two or more.

[0079] As an example, the frame 13 is composed of multiple side beams spliced ​​together. Multiple light strips 198 can be independently assembled into the multiple side beams one by one. After the side beams are spliced ​​together, the multiple light strips 198 are distributed in a ring.

[0080] As an example, only one light strip 198 can be provided. After the frame 13 is assembled, the entire light strip 198 is inserted into the annular receiving cavity 1381 through the annular assembly port 1382, so that the entire light strip 198 is connected end to end to form a ring.

[0081] In actual implementation, refer to Figures 1 to 3 During the forming process of the frame 13, a receiving cavity 1381 for accommodating the light strip 198 is machined into the inner side of the frame 13. Simultaneously, an assembly opening 1382 communicating with the receiving cavity 1381 is opened on the inner side of the frame 13 away from the chamber 121. A light-transmitting window 1383 is provided on the side near the chamber 121 and opposite to the receiving cavity 1381. During processing, the dimensional accuracy of the receiving cavity 1381, assembly opening 1382, and light-transmitting window 1383 is strictly controlled to ensure that the light strip 198 can be installed smoothly and that light can effectively pass through. The pre-prepared light strip 198 is inserted into the receiving cavity 1381 through the assembly opening 1382, and the light strip 198 is arranged along the extension direction of the receiving cavity 1381 to ensure that the light strip 198 is securely housed within the receiving cavity 1381. Align the inner side of the frame 13, which carries the light strip 198, with the mounting flare 126b of the inner liner 12 and insert it. The frame 13 and the inner liner 12 are assembled by the engagement of the second snap-fit ​​part 136 with the first snap-fit ​​part 126a. The inner liner 12 with the assembled frame 13 is then inserted into the outer shell 11 to complete the basic assembly of the refrigeration equipment 10. Then, foaming can begin. The insulation material is injected between the outer shell 11 and the inner liner 12 by pouring. After the insulation material has cured, a continuous and dense insulation layer is formed.

[0082] The refrigeration device 10 provided in this application embodiment accommodates the light strip 198 by providing a receiving cavity 1381 inside the frame 13, and a light-transmitting window 1383 is provided on the side near the compartment 121, so that the light emitted by the light strip 198 can directly illuminate the interior of the refrigeration device 10, providing uniform and bright lighting for the compartment 121, so that users can view the items, improve the user experience and display effect. Combined with the setting of the assembly port 1382, a convenient channel is provided for the installation and disassembly of the light strip 198, without complicated operations and tools, reducing the difficulty of assembly and maintenance, speeding up production efficiency, and reducing the inconvenience and cost increase of equipment use caused by maintenance difficulties. In addition, the receiving cavity 1381 provides a relatively closed space for the light strip 198, which can reduce the interference and damage of the external environment to the light strip 198, play a protective role, and thus extend the service life of the light strip 198.

[0083] In some embodiments, refer to Figure 3 The second section 12622 abuts against the inner side of the frame 13 away from the side of the compartment 121 to seal the assembly opening 1382.

[0084] In this embodiment, refer to Figure 3 The first snap-fit ​​portion 126a and the second snap-fit ​​portion 136 circumferentially snap together to form a first sealing interface. The first segment 12621 and the second segment 12622 form an installation flare 126b, which is interference-fitted with the inner side of the frame 13, so that the inner wall of the second segment 12622 is tightly fitted with the outer wall of the inner side of the frame 13, thereby forming a second sealing interface. The insulation material must continuously pass through the first and second sealing interfaces to flow into the receiving cavity 1381. The above-mentioned double sealing interface effectively reduces the possibility of insulation material overflowing into the receiving cavity 1381 from the assembly port 1382 during the foaming process. This reduces the risk of insulation material blocking the light strip 198 or affecting the normal light emission of the light strip 198, maintains the lighting display effect of the light strip 198, and provides users with a clear and bright lighting environment for the room 121.

[0085] The refrigeration device 10 provided in this application embodiment, through the structural design of the second section 12622 abutting against the inner side of the frame 13 away from the chamber 121 to seal the assembly port 1382, further effectively prevents the insulation material from overflowing from the assembly port 1382 during the foaming process, based on the sealing of the first snap-fit ​​part 126a and the second snap-fit ​​part 136. This significantly alleviates the situation of insulation material contaminating the lamp strip 198 and the light transmission window 1383 caused by overflow, and also reduces the compression of the lamp strip 198 by the insulation material, so that the lamp strip 198 is always in a clean and safe working environment, maintains good lighting performance, and thus extends the service life of the lamp strip 198.

[0086] In some embodiments, refer to Figure 3 A receiving groove 1391 is formed between the second snap-fit ​​portion 136 and the inner side of the frame 13. The first snap-fit ​​portion 126a is located in the receiving groove 1391 and divides the receiving groove 1391 into a part that communicates with the insulation layer and a part that is adjacent to the assembly opening 1382. The part of the receiving groove 1391 adjacent to the assembly opening 1382 is separated from the assembly opening 1382 by the second segment 12622.

[0087] In actual operation, if a small amount of insulation material still overflows through the gap between the first snap-fit ​​part 126a and the second snap-fit ​​part 136 during the foaming process, the insulation material cannot directly enter the receiving cavity 1381 because the first snap-fit ​​part 126a divides the receiving groove 1391 into a part communicating with the insulation layer and a part adjacent to the assembly port 1382. Instead, it flows from the part of the receiving groove 1391 communicating with the insulation layer into the part adjacent to the assembly port 1382. Thus, the part of the receiving groove 1391 adjacent to the assembly port 1382 can be regarded as an overflow buffer cavity, which buffers and slows down the high-speed impact of the flowing insulation material. Even if the amount of insulation material flowing into the part of the receiving groove 1391 adjacent to the assembly port 1382 gradually increases, the insulation material will squeeze the third section 12623, thereby further increasing the clamping force between the second section 12622 and the inner side of the frame 13, further optimizing the sealing effect of the second section 12622 on the assembly port 1382, forming a dynamic sealing reinforcement mechanism.

[0088] The refrigeration device 10 provided in this application embodiment, through the setting of the aforementioned receiving groove 1391 and the separation design of the first snap-fit ​​part 126a, extends the overflow path between the aforementioned first sealing interface and the second sealing interface, so that the part adjacent to the receiving groove 1391 and the assembly port 1382 serves as an overflow buffer chamber, effectively buffering the high-speed impact of the insulation material, so as to dissipate the kinetic energy of the overflow as much as possible, thereby effectively limiting the continuous flow of the overflow. At the same time, the foaming pressure can be converted into the pressing force of the second section 12622 on the inner side of the frame 13 by extruding the third section 12623, further strengthening the sealing interface contact pressure between the second section 12622 and the inner side of the frame 13, thereby maximizing the protection of the performance of the lamp strip 198 and maintaining a good lighting effect.

[0089] In some embodiments, refer to Figure 3 and Figure 4 The front side of the mouth frame 13 has a first clearance groove 1392, a portion of the front side of the outer shell 11 is located in the first clearance groove 1392, and the outer shell 11 does not protrude forward from the mouth frame 13.

[0090] In this embodiment, refer to Figure 3 and Figure 4The front end of the outer shell 11 is bent twice to form an inwardly open jaw. The outer side of the jaw frame 13 extends into the jaw, and the jaw of the outer shell 11 can apply a stable clamping force to the outer side of the jaw frame 13. The outer side of the jaw frame 13 is recessed rearward relative to the other parts of the jaw frame 13 to form a first clearance groove 1392. In this way, a part of the jaw of the outer shell 11 can be embedded in the receiving groove 1391 of the jaw frame 13, so that the front side of the outer shell 11 and the front side of the jaw frame 13 will not form a step structure.

[0091] The refrigeration device 10 provided in this application embodiment, by setting a first clearance groove 1392 in the frame 13 and embedding the front part of the outer shell 11 into the first clearance groove 1392, achieves that the outer shell 11 does not protrude forward from the frame 13, avoiding uneven structures such as protrusions or steps on the front surface of the refrigeration device 10, making the front surface of the refrigeration device 10 smoother and with simple and smooth lines, significantly improving the overall aesthetics and texture of the refrigeration device 10, better meeting consumers' aesthetic requirements for product appearance, while alleviating potential safety hazards caused by uneven structures such as protrusions or steps, and reducing the space for dust and stains to hide, thereby improving the safety of use and the ease of cleaning of the refrigeration device 10.

[0092] In some embodiments, refer to Figures 3 to 6 The compartment 121 includes a freezer compartment 121a and a refrigerator compartment 121b. The outer shell 11 includes an outer shell body 111 and a central beam 112. The central beam 112 is installed on the front side of the outer shell body 111 and is located on the front side of the insulation layer between the freezer compartment 121a and the refrigerator compartment 121b. The opening frame 13 is connected to both the outer shell body 111 and the central beam 112, and the opening frame 13 is provided with a first clearance groove 1392 in the area connected to the outer shell body 111 and the central beam 112.

[0093] In this embodiment, refer to Figures 3 to 6The inner liner 12 forming the freezer compartment 121a and the inner liner 12 forming the refrigerator compartment 121b are separated by a central beam 112 and an insulation layer located between the freezer compartment 121a and the refrigerator compartment 121b. In order to achieve stable installation of the inner liner 12 forming the freezer compartment 121a and the inner liner 12 forming the refrigerator compartment 121b on the refrigeration equipment 10, the side of the frame 13 corresponding to the refrigerator compartment 121b that is close to the freezer compartment 121a is connected to the central beam 112, and the other sides are connected to the outer shell body 111. Similarly, the side of the frame 13 corresponding to the freezer compartment 121a that is close to the refrigerator compartment 121b is connected to the central beam 112, and the other sides are connected to the outer shell body 111. Each side of the frame 13 corresponding to the refrigeration compartment 121b is provided with a first clearance groove 1392, and each side of the frame 13 corresponding to the freezer compartment 121a is provided with a first clearance groove 1392, so that the front surface of the outer shell body 111 and the front surface of the middle beam 112 do not protrude from the front surface of the frame 13.

[0094] The refrigeration device 10 provided in this application embodiment, through the structural design of the aforementioned central beam 112 installed on the front side of the outer shell 111 and located in front of the insulation layer between the freezer compartment 121a and the refrigerator compartment 121b, provides additional structural support for the refrigeration device 10. When the refrigeration device 10 is subjected to external forces, the central beam 112 can share some of the stress, reduce the deformation of the outer shell 111 and the insulation layer, improve the overall structural stability of the refrigeration device 10, and extend the service life of the refrigeration device 10. On the other hand, the frame 13 is connected to both the outer shell 111 and the central beam 112. Furthermore, the design of the first clearance groove 1392 makes the front surface of the refrigeration equipment 10 smoother and more aesthetically pleasing, avoiding protrusions or steps caused by unevenness in the connection parts, thereby improving the aesthetics and texture of the refrigeration equipment 10. At the same time, it alleviates the potential safety hazards caused by uneven structures such as protrusions or steps, and reduces the space for dust and stains to hide, thereby improving the safety of use and the ease of cleaning of the refrigeration equipment 10. On the other hand, the design of the first clearance groove 1392 provides accurate positioning for the installation of the outer shell 111 and the central beam 112, making the installation process simpler and faster.

[0095] In some embodiments, refer to Figure 7 The front side of the outer shell 111 is bent to form a multi-layer plate structure 1111, and the end of the central beam 112 has an extension section 1121. The extension section 1121 is stacked and connected with the multi-layer plate structure 1111 on the front side of the outer shell 111.

[0096] Among them, "multi-layer" means two or more layers.

[0097] For example, refer to Figure 7The multi-layer plate structure 1111 on the front side of the outer shell body 111 is a two-layer plate structure.

[0098] The main structure of the central beam 112 forms part of the front surface of the refrigeration device 10. Both ends of the central beam 112 have extension sections 1121, and each of the two extension sections 1121 is stacked and connected to two multi-layer plate structures 1111 on the front side of the outer shell body 111. The stacking method of the central beam 112 and the multi-layer plate structures 1111 can include: first, the central beam 112 can be stacked in front of the multi-layer plate structures 1111; second, the central beam 112 can be stacked behind the multi-layer plate structures 1111; and third, the central beam 112 can be stacked between the multi-layer plate structures 1111.

[0099] For example, refer to Figure 7 The central beam 112 is stacked after the multi-layer board structure 1111. In other words, the extension 1121 of the foamed central beam 112 is embedded in the insulation layer.

[0100] By stacking the extension 1121 at the end of the middle beam 112 with the multi-layer plate structure 1111 of the outer shell 111, sufficient connection area is provided between the middle beam 112 and the outer shell 111, making the connection more robust and reliable, enhancing the structural strength of the front side of the refrigeration equipment 10, and improving the overall stability of the refrigeration equipment 10 structure.

[0101] The connection method between the multi-layer board structure 1111 and the extension section 1121 may include, but is not limited to, bolt connection, riveting or welding. The appropriate connection method shall be selected according to different usage scenarios and requirements. This application embodiment does not limit this.

[0102] Furthermore, referring to Figure 7 The extension is bent to form a second clearance groove 11211, and the multi-layer board structure 1111 is installed in the second clearance groove 11211 so that the front surface of the multi-layer board structure 1111 does not protrude from the front surface of the central beam 112. In this way, uneven structures such as protrusions or steps at the connection between the outer shell body 111 and the central beam 112 are avoided, which significantly improves the overall aesthetics and texture of the refrigeration equipment 10. At the same time, it alleviates the potential safety hazards caused by uneven structures such as protrusions or steps, and reduces the space for dust and stains to hide on the outer shell 11, thereby further improving the safety of use and the ease of cleaning of the refrigeration equipment 10.

[0103] In some embodiments, the inner liner 12 is adapted to have a metal plate as the wall surface connected to the mouth frame 13, the mouth frame 13 is made of plastic, and the outer surface of the mouth frame 13 is covered with a metallic color layer.

[0104] The metallic color layer can be, but is not limited to, a metal film, a metal plating, or a metal coating, etc., and the embodiments of this application do not limit this.

[0105] For example, the outer surface of the frame 13 may be covered with a metal film.

[0106] It should be noted that the inner liner of the refrigeration equipment 10 is generally made of plastic. Due to the low strength of plastic inner liners, they may become brittle or deform at low or high temperatures. Prolonged use can easily lead to cracking, discoloration, and yellowing. Furthermore, plastic inner liners may absorb food odors, making them difficult to clean after long-term use. Additionally, plastic inner liners lack adequate antibacterial properties, making cleaning challenging. Therefore, some refrigeration equipment 10s incorporate metal inner liner structures to address the issues of cracking and discoloration associated with plastic inner liners over time, optimize the overall antibacterial performance of the refrigeration equipment, and reduce cleaning difficulty.

[0107] However, the front frame of the inner liner needs to be tightly sealed to the door to prevent cold air leakage. Unlike other parts of the inner liner, it does not have a flat and regular shape. Metal stamping technology is greatly limited when forming complex curved surfaces or small features, making processing difficult, mold costs high, and production yield low. Furthermore, even if the corresponding shape is stamped, metal stamping technology is very prone to springback and wrinkling defects for sharp edges or deep drawing features. With long-term use, the lower frame cannot withstand the stress brought by opening and closing the door, and is very prone to deformation or cracking, causing the door to fail to seal. In addition, once the frame is damaged, the entire inner liner needs to be replaced, resulting in high maintenance costs.

[0108] Understandably, since the inner liner 12 is suitable for having a metal plate wall connected to the frame 13, in other words, the left, top, right, and bottom walls of the inner liner 12 are metal plates, and the back wall of the inner liner 12 can be a metal plate to achieve an all-metal structure, or the back wall of the inner liner 12 can be a plastic plate to achieve a partially metal structure. The frame 13 is made of plastic, and the required cross-sectional shape can be formed by extrusion during production and processing. This solves the problem that it is difficult to stamp irregular cross-sectional shapes from metal plates, reduces the processing difficulty of the inner liner 12 and the frame 13, thereby improving the production yield of the refrigeration equipment 10 and reducing mold costs. Especially for the use scenario of the metal inner liner 12, it significantly reduces the risk of deformation or cracking of the frame 13 under the stress impact of long-term opening and closing of the door, maintains a long-term stable seal between the door and the frame 13, and since the plastic frame 13 and the metal inner liner 12 are produced and processed independently, even if the frame 13 is damaged, it is not necessary to replace the entire inner liner 12, thereby reducing maintenance costs.

[0109] In addition, since the outer surface of the plastic frame 13 is wrapped with a metal film, the plastic frame 13 has a metallic texture in appearance without increasing the processing difficulty of the frame 13, which is consistent with the appearance of the metal inner liner 12, thereby optimizing the overall appearance of the refrigeration equipment 10.

[0110] In some embodiments, refer to Figures 8 to 10 The inner liner 12 includes: a first shell 12a and a second shell 12b.

[0111] The first shell 12a includes a first plate 12a1, a second plate 12a2, and a third plate 12a3 connected by bending in sequence, with the first plate 12a1 and the third plate 12a3 arranged opposite to each other; the second shell 12b is connected to the first shell 12a to form an open compartment 121, wherein the first shell 12a and the second shell 12b are both metal plates, the second shell 12b includes a fourth plate 12b1 and a fifth plate 12b2 connected by bending, the fourth plate 12b1 is arranged opposite to the open, and the fourth plate 12b1 is connected to the first plate 12a1 to the third plate 12a3, the fifth plate 12b2 is connected to the first plate 12a1 and the third plate 12a3, and the fifth plate 12b2 is arranged opposite to the second plate 12a2.

[0112] The compartment 121 defined by the inner liner 12 may include, but is not limited to, a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc., and the embodiments of this application do not limit this.

[0113] The metal sheet may include, but is not limited to, stainless steel sheet, aluminum alloy sheet or galvanized steel sheet, etc., and the embodiments of this application do not limit this.

[0114] The first shell 12a and the second shell 12b can be joined together to form a cube structure with one side open for user access. The first shell 12a can be a three-section structure formed by bending a single piece of metal twice. For example, refer to... Figure 8 and Figure 10 The first shell 12a can be generally U-shaped. Specifically, the main body of the first plate 12a1, the second plate 12a2 and the third plate 12a3 are all flat plate structures.

[0115] The first shell 12a can be formed by bending metal sheets through sheet metal processing, three-point bending process or in-mold bending process, and this application embodiment does not limit this.

[0116] The second shell 12b can be a structure consisting of at least two sections formed by bending a single piece of metal sheet at least once, for example, referring to... Figure 8 and Figure 9 The second shell 12b can be roughly L-shaped. Specifically, the main body of the fourth plate 12b1 and the fifth plate 12b2 are both flat plate structures.

[0117] For example, refer to Figure 10When the inner liner 12 forms a freezer compartment, the second shell 12b needs to undergo three bending processes because space for the compressor compartment needs to be reserved at the bottom of the back side of the freezer compartment. The second shell 12b can be roughly M-shaped. Specifically, the main body of the fourth plate 12b1 is a flat plate structure, and the main body of the fifth plate 12b2 is a Z-shaped bent plate structure.

[0118] The first shell 12a can be formed by bending metal sheets through sheet metal processing, three-point bending process or in-mold bending process, and this application embodiment does not limit this.

[0119] The assembly method between the first shell 12a and the second shell 12b may include, but is not limited to, welding, threaded connection, riveting, gluing, edge crimping, bending and snap-fit ​​connection, or a combination of two or more of the above. This application embodiment does not limit this.

[0120] In related technologies, some refrigeration equipment 10 uses a metal panel to cover the inner wall of the plastic inner liner to alleviate the above problems. However, in practical applications, the assembly of the metal panel and the plastic inner liner is extremely complex and cumbersome, which seriously affects production efficiency. On the other hand, the introduction of the metal panel also significantly increases the weight of the entire inner liner structure, which is not conducive to the lightweight design of the product, thereby increasing material costs, processing costs, and transportation costs. Furthermore, it is difficult to achieve a seamless connection between the metal panel and the plastic inner liner, which can easily lead to the accumulation of dirt and grime, seriously affecting the cleanliness and hygiene of the refrigeration equipment 10.

[0121] In actual implementation, after the first shell 12a and the second shell 12b are manufactured and processed separately, the first shell 12a and the second shell 12b can be assembled into a cubic structure with an open side to form the inner liner 12. The connection between the first shell 12a and the second shell 12b can be made seamless through grinding, polishing and other treatments. On the one hand, both the first shell 12a and the second shell 12b are made of metal. Compared with traditional plastic inner liner, the metal inner liner 12 described in this application can withstand a greater storage weight because the tensile strength and impact resistance of metal are significantly higher than those of plastic. This effectively alleviates low-temperature embrittlement and high-temperature deformation, reduces the risk of deformation and cracking under long-term use, and thus extends the service life of the inner liner 12. Furthermore, because metal is not prone to absorbing moisture or food odors, and its surface is smooth and easy to clean, the natural antibacterial properties of the metal inner liner 12, combined with surface antibacterial treatment, can reduce bacterial growth during long-term use, reduce cleaning difficulty, and maintain a clean and hygienic internal environment of the refrigeration equipment 10. This can better meet the high hygiene standards of the medical and food industries. In addition, the metal inner liner 12 also has good thermal conductivity, which can improve temperature control efficiency, facilitate rapid temperature uniformity of the compartment 121, and reduce the energy consumption of the refrigeration equipment 10.

[0122] On the other hand, compared to the solution of covering a metal panel with a plastic inner liner, the inner liner 12 described in this application adopts an all-metal shell assembly method. The first shell 12a and the second shell 12b can be directly connected, eliminating the need for a complex process of bonding the plastic inner liner to the metal panel, reducing assembly steps, and thus significantly improving production efficiency. Although metal is relatively heavier than plastic, by rationally designing the shape and connection method of the first shell 12a and the second shell 12b, the thickness and structure of the metal plates can be optimized while meeting strength requirements, thereby reducing the overall weight. Moreover, it eliminates the need for complex production lines involving dual material procurement, inventory management, and composite processing, simplifying the supply chain and reducing material costs, processing costs, and transportation costs. In addition, due to the integral metal structure, the first shell 12a and the second shell 12b can achieve better connection and sealing. Compared to the connection between the metal panel and the plastic inner liner, it is less likely to have obvious gaps, thus effectively alleviating the problem of dirt accumulation, reducing the frequency of cleaning for users, and reducing the difficulty of cleaning, thereby significantly improving the cleanliness of the refrigeration equipment 10.

[0123] It should be noted that while there are technical concepts for metal-jointed inner liners, most designs involve forming a ring-shaped enclosure by bending a long metal sheet through four bends. This enclosure forms the top, bottom, left, and right walls of the inner liner, which is then connected to a metal back panel. However, this method presents significant challenges in actual production: First, because it forms a closed-loop enclosure, it cannot be formed in one piece of sheet metal and requires four progressive bends, making the process complex. Second, the closed-loop enclosure typically meets on one side, creating a seam that easily accumulates dirt and becomes unhygienic. Eliminating this seam requires substantial manpower and resources, hindering cost control. Third, all four edges of the back panel must connect to the enclosure, demanding extremely high precision in both the enclosure and the back panel. During actual processing, misalignment on one side is highly likely, resulting in a significantly lower yield rate for the inner liner than expected.

[0124] In some proposed designs for metal-paneled inner liners, a paper-folding technique is used: first, an irregularly shaped metal sheet (T-shaped, cross-shaped, or L-shaped) is cut out; then, it is bent to form an open inner liner; finally, the joints between the surfaces are connected to form a cube that is not closed on one side. However, this method is also impractical for production: firstly, the material waste during the cutting of the irregularly shaped metal sheet before bending is extremely significant, leading to a sharp increase in material costs; secondly, the excessive number of bends on a single sheet greatly increases processing difficulty and can easily weaken the sheet's strength; thirdly, the joints between the surfaces are difficult to align, or there are obvious seams on large surfaces, which easily accumulate dirt and become unhygienic.

[0125] The refrigeration device 10 provided in this application embodiment improves the overall structural strength of the inner liner 12 through the all-metal splicing design of the first shell 12a and the second shell 12b, thereby extending the service life of the inner liner 12 and optimizing the antibacterial and deodorizing properties and thermal conductivity of the inner liner 12, thus reducing cleaning difficulty and condensation. Furthermore, by splitting the first shell 12a into bent first plates 12a1 to third plates 12a3, and the second shell 12b into bent fourth plates 12b1 and fifth plates 12b2, the inner liner is simplified. The 12-assembly process reduces the stringent requirements for processing precision in rigid splicing, thereby significantly reducing processing difficulty and greatly improving production yield and efficiency, thus reducing overall costs and facilitating large-scale mass production. Combined with the one-panel-one-side assembly approach, it effectively alleviates the problem of dirt accumulation, reduces the frequency of user cleaning, and lowers the difficulty of cleaning, thereby significantly improving the cleanliness of the refrigeration equipment 10. At the same time, it maximizes the concealment of seams, reduces the negative impact of seam filling on appearance, and thus optimizes the user's experience.

[0126] In some embodiments, the first plate 12a1, the second plate 12a2 and the third plate 12a3 are each provided with a connection structure for connecting to the plate body of the second shell 12b.

[0127] In other embodiments, both the fourth plate 12b1 and the fifth plate 12b2 are provided with a connection structure for connecting to the plate body of the first shell 12a.

[0128] The connection structure may include, but is not limited to, overlapping edges, welding bevels, tongues, snaps, slots, or serrated edges, etc., and the embodiments of this application do not limit this.

[0129] Taking the implementation of the welded connection structure as an example, although the welding bevel, boss and serrated edge of the first shell 12a are complex, only one set of molds is needed to form the first shell 12a. The second shell 12b only needs to be matched with a simple planar structure, which not only reduces the number of molds and greatly reduces the mold cost, but also only requires increasing the processing accuracy of the first shell 12a. The second shell 12b can be produced in a standardized manner, reducing the complexity of the mold.

[0130] The refrigeration device 10 provided in this application embodiment is designed with connection structures for connecting the first plate 12a1, the second plate 12a2, and the third plate 12a3 to the plate body of the second shell 12b. The complex connection structure is concentrated in the first shell 12a, which has more plates. During mold manufacturing, the first shell 12a can be designed and processed in a more complex but uniform way, while the mold structure of the second shell 12b can be relatively simplified. Since the first shell 12a undertakes most of the structural design and processing tasks related to the connection with the second shell 12b, the processing of the connection structure minimizes the weakening of the overall strength, while reducing the complexity and processing difficulty of the mold of the second shell 12b, thereby reducing the overall mold manufacturing cost.

[0131] In some embodiments, refer to Figures 11 to 13 The first plate 12a1, the second plate 12a2 and the third plate 12a3 each include a main plate 126 and a flange 127. The flange 127 is used to cover the edge of the second shell 12b. The main plate 126 and the second shell 12b form the wall of the chamber 121.

[0132] The flange 127 can be designed as a right-angle flange structure, a rounded-corner flange structure, a rolled-edge flange structure, or a Z-shaped flange structure, etc., and the embodiments of this application do not limit this.

[0133] In this embodiment, refer to Figures 11 to 13 The first plate 12a1, the second plate 12a2, and the third plate 12a3 all have flanges 127 at their connection points with the first shell 12a. This allows the first shell 12a to be sealed to the second shell 12b via its own flanges 127. Furthermore, the fourth plate 12b1 and the fifth plate 12b2 are integrally embedded within the frame structure enclosed by the flanges 127 of the first plate 12a1, the second plate 12a2, and the third plate 12a3, achieving complete enclosure of all edges of the second shell 12b by the first shell 12a, thereby minimizing seams directly connecting to the outside. When the first shell 12a and the second shell 12b are fully assembled, the flanges 127 are exposed and not contained within the compartment 121. The main body 126 of the first plate 12a1, the main body 126 of the second plate 12a2, the main body 126 of the third plate 12a3, and the second shell 12b form the wall of the compartment 121.

[0134] The refrigeration device 10 provided in this application embodiment, by setting the connection structure as a flange 127 covering the edge of the second shell 12b, allows the flange 127 and the second shell 12b to be nested together. This increases the contact area between the first shell 12a and the second shell 12b. Compared with a simple planar connection, this provides greater friction and connection strength, reducing the probability of loosening or separation at the connection point when subjected to external forces. This improves the overall stability and reliability of the inner liner 12 and extends the fatigue life of the inner liner 12. At the same time, the covering of the flange 127 effectively reduces the friction between the first shell 12a and the second shell 12b. The gap between b reduces the leakage of gas or liquid through the gap, improving the sealing performance of the inner liner 12 and thus improving the refrigeration efficiency of the refrigeration equipment 10. Compared with welded, threaded, and riveted connections that are prone to staining, the flange 127 design can achieve a smooth inner wall, with no exposed screws, rivets, or welds on the inner wall of the compartment 121, further alleviating the problem of dirt accumulation. In addition, the flange 127 plays a positioning and fault tolerance role for the edge of the second shell 12b, allowing for certain dimensional tolerances without the need for high-precision alignment, significantly simplifying the assembly and positioning process of the first shell 12a and the second shell 12b, and further accelerating production efficiency.

[0135] In some embodiments, refer to Figure 14 , Figure 16 and Figure 17 ,in, Figure 14 The middle flange 127 is still in an intermediate state where it does not completely cover the edge of the first shell 12a, that is, the current poses of the first flange 1271 and the second flange 1272 have not yet been processed to the final state. Figure 16 and Figure 17 This is an exploded view of the processing steps of the first folded edge 1271 and the second folded edge 1272 during the connection of the first shell 12a and the second shell 12b. The folded edge 127 includes the first folded edge 1271 and the second folded edge 1272. The main body 126, the first folded edge 1271 and the second folded edge 1272 are sequentially bent and connected. The edge of the second shell 12b is sandwiched between the first folded edge 1271 and the second folded edge 1272.

[0136] In this embodiment, the forming of the first folded edge 1271 and the second folded edge 1272 can be achieved through the following process: a metal plate is bent at least once to form the first shell 12a; another metal plate is bent twice, and the first folded edge 1271 and the second folded edge 1272 are stamped at the subsequent splicing position. The first folded edge 1271 is at a right angle or close to a right angle with the main body 126. Sufficient space is reserved between the first folded edge 1271 and the second folded edge 1272 so that the edge of the second shell 12b can be easily inserted. The included angle between the first folded edge 1271 and the second folded edge 1272 can be a set angle, such as 25°, 30°, or 45°. The edges of the second shell 12b are inserted into the flanges 127 of the first plate 12a1, the second plate 12a2, and the third plate 12a3. Specifically, refer to... Figure 16 One side surface of the edge of the second shell 12b is fitted with the first folded edge 1271. Since there is sufficient clearance between the first folded edge 1271 and the second folded edge 1272, the other side surface of the edge of the second shell 12b is separated from the second folded edge 1272. After confirming that the first shell 12a is embedded in place, the tooling is used to rotate the raised second folded edge 1272 around the connection point of the first folded edge 1271 and the second folded edge 1272 toward the other side surface of the edge of the second shell 12b, until the second folded edge 1272 presses against the other side surface of the edge of the second shell 12b. In this way, the first folded edge 1271 and the second folded edge 1272 tightly clamp the edge of the second shell 12b.

[0137] The refrigeration device 10 provided in this application embodiment, through the clamping design of the first folded edge 1271 and the second folded edge 1272 on the edge of the second shell 12b, on the one hand, provides stronger constraint force compared with single-layer flange connection, reduces the risk of displacement after assembly, thereby greatly improving the connection stability of the overall structure of the inner liner 12, and effectively maintaining the quality and consistency of the inner liner 12 assembly; on the other hand, the first folded edge 1271 and the second folded edge 1272 can form a tortuous labyrinth-like sealing path with the edge of the second shell 12b, without the need for additional sealing components, and can also effectively prevent liquid, gas and other media from leaking from the splicing position, further optimizing the sealing performance of the inner liner 12, thereby further improving the refrigeration efficiency of the refrigeration device 10; and on the other hand, during the assembly process, the edge of the second shell 12b can be easily inserted between the first folded edge 1271 and the second folded edge 1272, playing a good positioning role, and the operator can quickly and accurately assemble the first shell 12a and the second shell 12b, improving the assembly efficiency.

[0138] In some embodiments, refer to Figure 18 The edges of the main body 126, the first folded edge 1271, the second shell 12b, and the second folded edge 1272 are stacked sequentially.

[0139] In this embodiment, refer to Figures 16 to 18 , Figures 16 to 18 This is an exploded view of the processing steps of the first folded edge 1271 and the second folded edge 1272 during the connection of the first shell 12a and the second shell 12b. First, the edge of the second shell 12b is inserted between the initially bent first folded edge 1271 and the second folded edge 1272. After positioning, the second folded edge 1272 is further bent to press firmly against the edge of the second shell 12b. After confirming that each edge of the second shell 12b is clamped by the first folded edge 1271 and the second folded edge 1272 of each flange 127, a tooling is used to rotate the entire assembly consisting of the first folded edge 1271, the edge of the second shell 12b, and the second folded edge 1272 around the connection point between the first folded edge 1271 and the main body 126 toward the outer surface of the main body 126, until the side of the first folded edge 1271 facing away from the second folded edge 1272 presses firmly against the outer surface of the main body 126. (Refer to...) Figure 18 In the final state, the main body 126, the first folded edge 1271 and the second folded edge 1272 are generally S-shaped bends, and the clamping part of the second shell 12b and the unclamped part of the second shell 12b are generally L-shaped bends.

[0140] The refrigeration device 10 provided in this application embodiment is constructed by sequentially stacking the main body 126, the first folded edge 1271, the edges of the second shell 12b, and the second folded edge 1272. After the first folded edge 1271 and the second folded edge 1272 clamp the edge of the second shell 12b, the entire assembly consisting of the first folded edge 1271, the edges of the second shell 12b, and the second folded edge 1272 is further pushed flat towards the main body 126, reducing the volume of the inner liner 12 and minimizing its space occupation, thereby improving the space utilization rate of the entire refrigeration device 10. This creates an interlocking structure between the second shell 12b and the flange 127, further increasing the bonding force between the first shell 12a and the second shell 12b, and further reducing the risk of displacement after assembly. This maximizes the connection stability of the overall structure of the inner liner 12. In addition, the bending point between the main body 126 and the first flange 1271 is no longer exposed. During the foaming process, the stress weak points between the main body 126 and the first flange 1271 will not be subjected to foaming pressure and impact, thereby reducing the risk of fatigue fracture of the first shell 12a.

[0141] In other embodiments, the area in the second shell 12b that is not opposite to the first folded edge 1271, the second folded edge 1272, the edge of the second shell 12b, and the first folded edge 1271 are sequentially stacked.

[0142] In this embodiment, after confirming that each edge of the second shell 12b is clamped by the first folded edge 1271 and the second folded edge 1272 of each flange 127, the entire assembly consisting of the first folded edge 1271, the edge of the second shell 12b, and the second folded edge 1272 is rotated around the connection point between the first folded edge 1271 and the main body 126 toward the outer surface of the area in the second shell 12b that is not opposite to the first folded edge 1271, until the side surface of the second folded edge 1272 facing away from the first folded edge 1271 presses against the outer surface of the area in the second shell 12b that is not opposite to the first folded edge 1271. In the final state, the main body 126, the first folded edge 1271, and the second folded edge 1272 are generally q-shaped bends, and the clamping portion and the unclamped portion of the second shell 12b are generally J-shaped bends.

[0143] The refrigeration device 10 provided in this application embodiment is constructed by sequentially stacking the area of ​​the second shell 12b that is not opposite to the first folded edge 1271, the second folded edge 1272, the edge of the second shell 12b, and the first folded edge 1271. After the first folded edge 1271 and the second folded edge 1272 clamp the edge of the second shell 12b, the entire structure consisting of the first folded edge 1271, the edge of the second shell 12b, and the second folded edge 1272 is pushed flat towards the area of ​​the second shell 12b that is not opposite to the first folded edge 1271. This reduces the volume of the inner liner 12 and the space occupied by the inner liner 12, thereby improving the space utilization of the entire refrigeration device 10. At the same time, it forms an interlocking structure between the second shell 12b and the folded edge 127, further increasing the bonding force between the first shell 12a and the second shell 12b, further reducing the risk of displacement after assembly, and thus maximizing the connection stability of the overall structure of the inner liner 12.

[0144] In some embodiments, refer to Figure 8 and Figure 18 The area in the second shell 12b that is not opposite to the first folded edge 1271 is used to form part of the inner wall of the compartment 121.

[0145] Understandably, referring to Figure 8 and Figure 18Since the area in the second shell 12b that is not opposite to the first folded edge 1271 directly serves as part of the inner wall of the compartment 121, after assembly, the connection between the first shell 12a and the second shell 12b is cleverly hidden and weakened from the appearance. The clamping structure of the first folded edge 1271 and the second folded edge 1272 makes the connection neater, without obvious splicing marks or protrusions. It is difficult for users to directly observe the process seams during use. Even if there are some small seams, they will not have an obvious impact on the appearance and user experience of the product because they are covered by the structure of the first folded edge 1271 and the second folded edge 1272 or are in a position that is not easy to detect. This makes the appearance of the entire inner liner 12 smoother and more beautiful, thereby improving the overall quality of the refrigeration equipment 10. In addition, the area of ​​the second shell 12b that is not opposite to the first folded edge 1271 serves as part of the inner wall of the compartment 121, which together with the main body 126 of the first shell 12a forms the inner wall of the compartment 121, making the interior of the compartment 121 look more complete and unified. This integrated design reduces the sense of division and discontinuity inside the compartment 121. At the same time, the flat and continuous inner wall is easy to clean and maintain, reducing dead corners and bacterial growth, thereby improving the practicality and convenience of the refrigeration equipment 10.

[0146] In some embodiments, refer to Figures 9 to 13 and Figure 15 A first transition section 12b3 is provided between the fourth plate 12b1 and the fifth plate 12b2. The first folded edge 1271 on the first plate 12a1 and the third plate 12a3 at the end opposite to the second plate 12a2 forms a second transition section 1261 that cooperates with the first transition section 12b3. The first transition section 12b3 and the second transition section 1261 are sealed together.

[0147] In this embodiment, refer to Figures 9 to 13 and Figure 15 Since the second shell 12b is formed by bending a whole piece of metal sheet, the bending point of the fourth plate 12b1 and the fifth plate 12b2 will form an arc-shaped first transition section 12b3, i.e., the R-corner area. Correspondingly, in order to match the first transition section 12b3, the corresponding connection positions of the first plate 12a1 and the third plate 12a3 can be cut out with an arc-shaped second transition section 1261. The second transition section 1261 can be folded outward relative to the main body 126. The two ends of the second transition section 1261 can be connected to the flange 127. The second transition section 1261 of the first plate 12a1 and the second transition section 1261 of the third plate 12a3 are respectively sealed and fitted with the two end edges of the first transition section 12b3 of the first shell 12a.

[0148] The sealing method between the first transition section 12b3 and the second transition section 1261 may include, but is not limited to, heat sealing with a sealing film, bonding with sealant, applying sealing tape, hot melt sealing, sealing gasket sealing, or a combination of two or more of the above. This application embodiment does not limit this.

[0149] For example, in some embodiments, adhesive is applied to the mating surfaces between the first transition section 12b3 and the second transition section 1261 to achieve sealing. Furthermore, adhesive can also be applied to the mating surfaces between the flange 127 and the second shell 12b to further seal the surfaces.

[0150] For example, in other embodiments, a heat-sealing sealing film is used to achieve a seal between the mating surfaces of the first transition section 12b3 and the second transition section 1261.

[0151] For example, in some other embodiments, adhesive tape is applied to the outer surfaces of the first transition section 12b3 and the second transition section 1261 to seal the gap between the first transition section 12b3 and the second transition section 1261 and the outside world.

[0152] The refrigeration device 10 provided in this application embodiment, through the structural design of the sealing cooperation between the first transition section 12b3 and the second transition section 1261, takes into account that the complex shape of the bent part on the second shell 12b is different from the flat plate surface and it is difficult to achieve a connection and seal using the aforementioned flange 127. The second transition section 1261 matching the first transition section 12b3 is precisely machined on the first shell 12a, so that the shape of the first transition section 12b3 and the second transition section 1261 is completely matched. Combined with auxiliary sealing measures, reliable sealing of the first shell 12a and the second shell 12b in the non-flat area is achieved. This not only extends the sealing path between the first shell 12a and the second shell 12b, but also disperses the stress concentration of the first transition section 12b3, and optimizes the sealing performance of the entire inner liner 12 to the maximum extent, thereby improving the refrigeration efficiency of the refrigeration device 10.

[0153] In some embodiments, refer to Figure 15 The first fold 1271 is connected to the second fold 1272 in the area outside the second transition section 1261.

[0154] Understandably, referring to Figure 15 Since the first fold 1271 connects to the second fold 1272 in the area outside the second transition section 1261, no secondary bending will occur at the complex curved surface of the first transition section 12b3 and the second transition section 1261, when performing... Figure 17 and Figure 18When the edges of the first folded edge 1271, the second folded edge 1272, and the second shell 12b are flattened, the resistance to material deformation is greatly reduced, thereby reducing the difficulty of the flattening operation and further accelerating the production rate. At the same time, the second folded edge 1272 is not constrained by the first transition section 12b3, which reduces the risk of obvious wrinkles in the second folded edge 1272 due to the deformation and tearing force of the first transition section 12b3 during the flattening process. After flattening, there are relatively uniform wrinkles only at the first transition section 12b3 and the second transition section 1261, thereby maintaining a reliable connection and good sealing between the folded edge 127 and the edge of the second shell 12b, optimizing the flattening effect, and thus improving the production yield.

[0155] In some embodiments, refer to Figure 14 A corner opening 128 is formed between the corner of the fourth plate 12b1 and the crease of the first shell 12a, and the corner opening 128 is filled with structural adhesive.

[0156] In this embodiment, refer to Figure 14 After the two flanges 127 of the two adjacent plates of the first shell 12a are assembled with the two edges of the fourth plate 12b1, the junction of the two adjacent flanges 127 and the corner of the fourth plate 12b1 are difficult to fit completely, thus forming a corner opening 128. The corner opening 128 connects the compartment 121 to the outside when it is not sealed. In order to optimize the sealing performance of the inner liner 12, after the first shell 12a and the second shell 12b are assembled, structural adhesive is filled into the multiple corner openings 128 formed at the connection. After the structural adhesive cures, it forms a rigid filling layer, which is the sharp corner area of ​​the inner liner 12.

[0157] The structural adhesive may include, but is not limited to, epoxy resin structural adhesive, polyurethane structural adhesive, or silicone structural adhesive, etc., and the embodiments of this application do not limit it.

[0158] The refrigeration equipment 10 provided in this application embodiment, through the above-described design of filling the corner 128 with structural adhesive, effectively seals the dangerous leakage channel formed between the corner of the fourth plate 12b1 and the crease of the first shell 12a, reduces the leakage of internal cold air or condensate, and effectively solves the problem of excessive overflow of insulation material from the corner 128 during the foaming process. It achieves maximum sealing of the joint area between the first shell 12a and the second shell 12b, and maximizes the production yield of the inner liner 12. At the same time, the rigid filling layer formed after the structural adhesive cures reduces the propagation of microcracks at the corner 128, significantly extends the fatigue life of the inner liner 12, and the structural adhesive can also compensate for the assembly error at the corner 128, reduce the assembly accuracy requirements, thereby improving production efficiency. In addition, there is no need to design a complex mold structure to compensate for the corner 128, thereby reducing mold costs.

[0159] The embodiments of this application will be described in detail below from two different implementation perspectives.

[0160] I. In some embodiments, reference is made to Figure 8 The first plate 12a1 and the third plate 12a3 form the side wall of the compartment 121, the second plate 12a2 forms the top wall of the compartment 121, the fourth plate 12b1 forms the back wall of the compartment 121, and the fifth plate 12b2 forms the bottom wall of the compartment 121.

[0161] In this embodiment, refer to Figure 8 The continuously bent first plate 12a1, second plate 12a2, and third plate 12a3 form the left side wall, top wall, and right side wall of the compartment 121, respectively. The continuously bent fourth plate 12b1 and fifth plate 12b2 form the back wall and bottom wall of the compartment 121, respectively. The rear side of the first plate 12a1 is provided with a flange 127 for covering the left edge of the fourth plate 12b1, and the bottom of the first plate 12a1 is also provided with a flange 127 for covering the left edge of the fifth plate 12b2. The rear side of the second plate 12a2 is provided with a flange 127 for covering the top edge of the fourth plate 12b1, and the rear side of the third plate 12a3 is provided with a flange 127 for covering the right edge of the fourth plate 12b1. The bottom of the third plate 12a3 is also provided with a flange 127 for covering the right edge of the fifth plate 12b2.

[0162] 2. In some embodiments, the first plate 12a1 and the third plate 12a3 form the side walls of the compartment 121, the second plate 12a2 forms the bottom wall of the compartment 121, the fourth plate 12b1 forms the back wall of the compartment 121, and the fifth plate 12b2 forms the top wall of the compartment 121.

[0163] In this embodiment, the continuously bent first plate 12a1, second plate 12a2, and third plate 12a3 form the left side wall, bottom wall, and right side wall of the compartment 121, respectively, while the continuously bent fourth plate 12b1 and fifth plate 12b2 form the back wall and top wall of the compartment 121, respectively. The rear side of the first plate 12a1 is provided with a flange 127 for covering the left edge of the fourth plate 12b1, and the top of the first plate 12a1 is also provided with a flange 127 for covering the left edge of the fifth plate 12b2. The rear side of the second plate 12a2 is provided with a flange 127 for covering the bottom edge of the fourth plate 12b1, and the rear side of the third plate 12a3 is provided with a flange 127 for covering the right edge of the fourth plate 12b1. The top of the third plate 12a3 is also provided with a flange 127 for covering the right edge of the fifth plate 12b2.

[0164] The refrigeration equipment 10 provided in this application embodiment, through the spatial layout design of the first plate 12a1 to the fifth plate 12b2, provides multiple assembly schemes for selection. The appropriate assembly method can be selected according to actual storage needs and accessory integration requirements, thereby increasing the diversity and flexibility of the inner liner 12 structure. At the same time, the clear division of labor among the plates makes the structure of the inner liner 12 clearer, which facilitates planning and operation in the design and manufacturing process. Each part can be designed and processed in a targeted manner according to its functional requirements, improving production efficiency and product quality. In addition, the standardized plate layout also allows the inner liner 12 to better match the outer shell 11 of the refrigeration equipment 10, reducing installation gaps caused by irregular shapes and improving the overall space utilization efficiency.

[0165] In some embodiments, refer to Figures 8 to 10 and Figure 13 The inner liner 12 also includes: drainage component 197.

[0166] The bottom and back walls of the compartment 121 are provided with notches 1291. The drainage component 197 is connected to the bottom and back walls of the compartment 121 to seal the notches 1291, and the drainage component 197 is provided with a drain outlet 1971.

[0167] Drainage outlet 1971 can be set one or more, multiple means two or more.

[0168] The shape of the drain outlet 1971 may include, but is not limited to, a circle, a square, an ellipse, a polygon, or an irregular shape, and the embodiments of this application do not impose such limitations.

[0169] As an example, the edge of the drain element 197 can be sealed to the outer periphery of the notch 1291.

[0170] The sealing method between the edge of the drainage component 197 and the outer periphery of the notch 1291 may include, but is not limited to, elastic sealing ring sealing, sealing membrane heat sealing, liquid sealant bonding, sealing tape application, heat melt sealing or sealing gasket sealing, etc., and the embodiments of this application do not limit this.

[0171] The sealing material may include, but is not limited to, PE (Polyethylene) film, silicone rubber, or polyurethane elastomer, etc., and the embodiments of this application do not limit this.

[0172] The area of ​​the sealing interface between the edge of the drainage component 197 and the outer periphery of the notch 1291 can be customized according to actual needs, and this application embodiment does not limit this.

[0173] In this embodiment, refer to Figures 8 to 10 and Figure 13With the fourth plate 12b1 and the fifth plate 12b2 forming the back wall and bottom wall of the compartment respectively, the drain component 197 can be designed as an L-shape. The notch 1291 can be distributed at the bend between the fourth plate 12b1 and the fifth plate 12b2, i.e., the first transition section 12b3 between the fourth plate 12b1 and the fifth plate 12b2. This reduces the risk of condensate accumulation in the first transition section 12b3. Furthermore, the edge of the notch 1291 can extend beyond the first transition section 12b3 onto the fourth plate 12b1, thereby optimizing the sealing effect between the drain component 197 and the notch 1291. The size of the drain component 197 is larger than the size of the notch 1291, thus providing a structural basis for the seal. Before the insulation layer is formed in the refrigeration equipment 10, the drain component 197 can be pre-installed at the notch 1291 and the notch 1291 can be sealed from the outside to avoid the problem of cleaning dead zones caused by the stepped structure formed by internal assembly.

[0174] It should be noted that, in addition to fixing the drainage component 197 by pre-embedding the insulation layer, additional connecting structures such as adhesive, screws, rivets or clips can be added for further reinforcement, and this application embodiment does not limit this.

[0175] The refrigeration device 10 provided in this application embodiment provides a clear drainage channel for condensate through the aforementioned drainage component 197. When condensate is generated in the inner liner 12, it can naturally converge to the bottom wall of the compartment 121, and then flow into the drainage component 197 through the notch 1291, and finally be discharged from the drain outlet 1971. This reduces the long-term accumulation of condensate in the inner liner 12, reduces the risk of corrosion, bacterial growth, or odor caused by water accumulation in the inner liner 12, thereby improving the cleanliness of the compartment 121 of the inner liner 12 under long-term use, optimizing the user's experience, and extending the service life of the inner liner 12.

[0176] In some embodiments, refer to Figure 9 , Figure 10 and Figure 13 At least one of the bottom wall and back wall of the compartment 121 is provided with a first positioning structure 1292, and the drainage component 197 is provided with a second positioning component 1972, which is positioned and engaged with the first positioning structure 1292.

[0177] The first positioning structure 1292 may include, but is not limited to, protrusions, grooves or holes, and the second positioning element 1972 may include, but is not limited to, protrusions, grooves or holes that match the first positioning structure 1292. This application embodiment does not limit this.

[0178] For example, refer to Figure 9 , Figure 10 and Figure 13The first positioning structure 1292 may include a protrusion that is provided on the back wall of the compartment 121 and protrudes outward, and the second positioning member 1972 may include a groove provided at the corresponding position of the drain member 197.

[0179] The first positioning structure 1292 and the second positioning element 1972 can be set as one, or multiple can be set separately in a one-to-one correspondence, where multiple means two or more.

[0180] The refrigeration equipment 10 provided in this application embodiment, through the positioning cooperation of the first positioning structure 1292 and the second positioning member 1972, enables the drain member 197 to be quickly and accurately positioned at the notch 1291 on the bottom wall and back wall of the compartment 121 during the installation process. This effectively solves the problems of poor sealing and poor drainage caused by the deviation of the installation position of the drain member 197, improves the assembly accuracy and quality of the drain member 197, and when assembling the drain member 197, the drain member 197 can be initially positioned by the cooperation of the positioning member before being fixedly connected. Using this method of positioning first and then fixing makes the assembly process simpler and more efficient, thereby reducing assembly time and labor costs.
