Description

Technical Field

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

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

[0003] Since refrigerated display cases used in retail settings such as supermarkets and shopping malls require display and advertising functions, lightbox components are installed on the top of the display cases to achieve both lighting and advertising purposes. The lightbox components are primarily used to install LED lights and to provide sealed protection for the LED lights and surrounding wiring.

[0004] In existing technologies, lightbox assemblies are mainly made of sheet metal, resulting in thin-plate structures. During production and installation, burrs and sharp edges on the sheet metal parts are prone to forming, affecting the appearance of the freezer. Furthermore, sheet metal parts are susceptible to warping and deformation, requiring multiple screws to secure them to the freezer body, leading to low production and installation efficiency. On the other hand, the top of the lightbox assembly needs to withstand pressure during transportation and actual use, but the strength of sheet metal lightboxes is insufficient to meet user requirements. Summary of the Invention

[0005] Based on existing technologies, a cooling device is provided to improve the problems of low installation efficiency and insufficient structural strength between the light box and the cabinet.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a first extension and a second extension are respectively provided on the left and right sides above the top wall of the housing; a light box is disposed above the housing and between the first extension and the second extension; a lampshade is disposed on the front side of the light box, and a lamp assembly is disposed inside the lampshade; wherein, the light box includes a top plate disposed on the top wall of the refrigeration device; a peripheral side plate is provided extending downward from the peripheral side edge of the top plate, and the peripheral side plate is integrally injection molded with the top plate; the left and right side walls of the peripheral side plate are limited between the first extension and the second extension, and the bottom of the peripheral side plate is supported and fixed to the top wall of the housing.

[0007] The above technical solution has the following advantages or beneficial effects: By using an integral injection molding process to form the top and side panels of the lightbox, and molding it in one step with a high-precision mold, the finished lightbox has smooth and flat edges without any sharp edges or burrs, easily achieving aesthetically pleasing shapes such as rounded corners and curved surfaces. Moreover, the overall structure of the lightbox has no splicing gaps, and the integral injection-molded box-like structure formed by the top and side panels is a continuous whole. When the top wall of the refrigeration unit is under stress, the stress can be dispersed and transferred along this integral structure of the top and side panels, distributing the pressure to the top wall of the box, thus significantly improving the overall pressure resistance. Regarding the installation of the lightbox, it is embedded between the first extension and the second extension. During installation, simply insert the left and right sides of the lightbox's side panels from top to bottom along the first and second extensions, without manually adjusting the left and right position of the lightbox. Then, fix the lightbox to the top of the box. Compared to lightbox structures formed by sheet metal parts, it eliminates the need for multiple manual adjustments to align the holes between the sheet metal parts and the first and second extensions, reducing installation difficulty and effectively improving installation efficiency. Furthermore, the light box is embedded inside the first extension and the second extension, which extend upward from both sides of the box body, making the appearance of the refrigeration device more integrated and improving the overall aesthetics of the refrigeration device.

[0008] In some embodiments of this application, a cooling device is provided. The light box further includes a fixing plate, which extends from the bottom of the peripheral side plate toward the outside of the light box. The fixing plate and the peripheral side plate are integrally injection molded. The fixing plate is attached and fixed to the top wall of the box body.

[0009] Another technical solution mentioned above has the following advantages or beneficial effects: The fixing plate, serving as the connection structure between the lightbox and the cabinet, is attached to the top wall of the cabinet, increasing the contact area between them. Furthermore, by providing a fixing plate at the bottom of the side panels, operators can directly connect to the top of the cabinet via the fixing plate. Compared to the existing solution that uses multiple sheet metal parts to form the lightbox structure on the top of the cabinet, it eliminates the need for screws, bolts, and other connectors to be individually connected to the multiple connecting holes on the first and second extensions. This avoids the need for multiple manual adjustments to the connection position due to the cabinet's tendency to shrink and deform after foaming, which complicates installation and can cause appearance problems with the cooling device. The installation process of the lightbox is thus more convenient.

[0010] In some embodiments of this application, a refrigeration device is provided, wherein a clearance groove is formed on the outer side of the rear sidewall of the peripheral side plate, and the fixing plate is located at the bottom of the clearance groove.

[0011] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the fixing plate is set at the bottom of the clearance groove, which avoids the fixing plate extending outward to the top outside of the box and thus occupying too much horizontal space of the box. While ensuring the fixed area of ​​the fixing plate and the top of the box, it can also improve the utilization rate of the top space of the box, making the structure of the light box more compact.

[0012] In some embodiments of this application, a cooling device is provided, wherein the top plate and the peripheral side plate enclose a receiving cavity, the bottom of the peripheral side plate encloses a box opening communicating with the receiving cavity, and the top wall of the box closes the box opening; the receiving cavity is used to receive the electronic control part of the lamp assembly.

[0013] Another technical solution described above has the following advantages or beneficial effects: The cavity formed by the top plate and the side plates provides an integrated installation area for the electrical control components. The entire light box is placed on top of the enclosure, and the opening at the bottom of the side plates is sealed by the top wall of the enclosure, preventing the electrical control components of the light assembly from being installed separately or exposed to other environments, thus improving the protection of the electrical control components. Furthermore, the top plate and side plates of the light box provide a rigid protective shell for the electrical control components. When the top of the light box is subjected to pressure, the top plate and side plates can directly withstand the external force, preventing the electrical control components from being crushed or damaged.

[0014] In some embodiments of this application, a refrigeration device is provided. The first extension includes a first extension wall extending upward from the left side wall of the housing and protruding above the top wall of the housing; a second extension wall extending upward from the left side of the top wall of the housing; a first connecting wall connecting the tops of the first extension wall and the second extension wall; a first foaming cavity is provided in the first extension, which is formed between the first extension wall, the second extension wall and the first connecting wall; the second extension includes a third extension wall extending upward from the right side wall of the housing and protruding above the top wall of the housing; a fourth extension wall extending upward from the right side of the top wall of the housing; a second connecting wall connecting the tops of the third extension wall and the fourth extension wall; a second foaming cavity is provided in the second extension, which is formed between the third extension wall, the fourth extension wall and the second connecting wall.

[0015] Another technical solution described above has the following advantages or beneficial effects: By integrally extending the first extension and the second extension to the top of the housing, and by integrally foaming the first extension and the second extension with the housing, gaps can be avoided between the first extension and the housing, as well as between the second extension and the housing, thus improving the aesthetics of the refrigeration device. Furthermore, the tops of the first extension and the second extension can form the top wall of the refrigeration device with the top panel of the lightbox. When the top of the refrigeration device supports heavy objects or bears gravity during transportation, the integral foaming of the first extension and the housing can improve the structural strength of the top of the refrigeration device, meeting the user's need to place heavy objects on top.

[0016] In some embodiments of this application, a cooling device is provided, wherein the lampshade is a cover with an opening on the rear side; The cooling device also includes a reinforcing plate, which is located at the rear opening of the lampshade, and the front side of the reinforcing plate and the lampshade enclose a lamp cavity; the reinforcing plate is fixedly connected to the front side wall of the peripheral plate; the lamp assembly is located inside the lamp cavity and is fixedly connected to the reinforcing plate.

[0017] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by fixing the reinforcing plate to the front side wall of the peripheral side plate, a stable installation base can be provided for the lamp assembly. The lamp assembly is installed on the reinforcing plate, so that the lamp assembly can be firmly installed on the light box, avoiding problems such as unstable lighting or poor contact caused by the shaking of the lamp assembly, and improving the reliability and stability of the lamp assembly.

[0018] In some embodiments of this application, a refrigeration device is provided, wherein the front sidewall of the peripheral side plate is provided with a buckle; the reinforcing plate is provided with a slot corresponding to the buckle, and the buckle is aligned and engaged in the slot so that the front sidewall of the peripheral side plate is fixedly connected to the back of the reinforcing plate.

[0019] Another technical solution described above has the following advantages or beneficial effects: By setting a buckle on the front sidewall of the peripheral side plate and a corresponding slot on the reinforcing plate, the front sidewall of the peripheral side plate and the back of the reinforcing plate can be fixedly connected by the buckle being aligned and engaged in the slot. This snap-fit ​​connection method eliminates the need for additional fasteners such as screws, as well as complex tools and operating procedures, greatly simplifying the installation process and significantly improving production and installation efficiency.

[0020] In some embodiments of this application, a cooling device is provided, wherein the lampshade is a cover with a rear opening, and the rear edge of the lampshade is fixed to the front wall of the peripheral side plate; the interior of the lampshade and the front wall of the peripheral side plate enclose a lamp cavity; the lamp assembly is disposed in the lamp cavity and fixedly connected to the front wall of the peripheral side plate.

[0021] Another technical solution mentioned above has the following advantages or beneficial effects: To further improve installation efficiency and reduce installation difficulty, the lamp assembly can be directly fixed to the front wall of the peripheral side panel of the light box. Since the light box is integrally injection molded with the top plate and peripheral side panel, it has good structural strength. Thus, the light box can also integrate the structure and function of the reinforcing plate. The reinforcing plate, as an additional component, needs to be purchased and installed separately. Integrating the reinforcing plate into the light box reduces the number of components in the cooling unit, resulting in a simpler structure and reducing assembly errors that may result from too many components. Furthermore, operators do not need to install the reinforcing plate first and then connect the lamp assembly to the reinforcing plate, reducing installation steps and operational difficulty.

[0022] In some embodiments of this application, a cooling device is provided, wherein a connecting rib is provided on the front wall of the peripheral side plate, the connecting rib extends into the lamp cavity, and a slot is provided on the connecting rib; a buckle is provided on the rear edge of the lamp cover, and the buckle is correspondingly inserted into the slot.

[0023] Another technical solution described above has the following advantages or beneficial effects: the connecting rib extends into the lamp cavity, providing additional support for the connection between the lampshade and the surrounding side panel. Specifically, the slots on the connecting ribs correspond to the snap-fit ​​fasteners on the rear edge of the lampshade. During installation, the snap-fit ​​fasteners can be accurately inserted into the slots, forming a tight connection between the lampshade and the surrounding side panel, further improving the stability of the connection. Regarding ease of installation, the connection between the light box and the lampshade uses a snap-fit ​​and slot-fit method, eliminating the need for additional tools and complex operating procedures.

[0024] In some embodiments of this application, a cooling device is provided, wherein two limiting buckles are provided on the front wall of the peripheral side plate, and the two limiting buckles are arranged vertically opposite each other; the limiting buckles are integrally injection molded with the peripheral side plate; the upper and lower sides of the lamp assembly are respectively engaged with the limiting buckles; the lamp assembly is provided with limiting holes; positioning posts are provided on the front wall of the peripheral side plate, and the positioning posts are spaced apart on one side of the limiting buckles, and the positioning posts are correspondingly inserted into the limiting holes.

[0025] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the corresponding insertion of the positioning post and the limiting hole can not only play a role in pre-positioning the connection between the lamp assembly and the peripheral side plate, but also play a double fixing role in conjunction with the snap-fit ​​of the limiting buckle. Specifically, the limiting buckle snaps and fixes the lamp assembly from the vertical direction to prevent the lamp assembly from loosening or falling off in the vertical direction, while the insertion of the positioning post and the limiting hole positions and fixes the lamp assembly from the horizontal direction to prevent the lamp assembly from moving in the horizontal direction. This can greatly improve the stability of the lamp assembly installation. Attached Figure Description

[0032] 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.

[0033] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0034] like Figure 1As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0035] In some embodiments, the housing 1 includes a refrigeration compartment, which can serve as an independent storage space. The refrigeration compartment may have an opening, allowing users to store food within it. Multiple refrigeration compartments may be provided.

[0036] In some embodiments, multiple refrigeration chambers may be provided, which may include freezers, refrigerators, and variable temperature compartments, etc., to meet different refrigeration needs such as freezing, refrigeration, and variable temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigeration chambers may be arranged vertically or horizontally.

[0037] In some embodiments, the refrigeration device may include a liner (not shown in the figure). A refrigeration chamber may be formed inside the liner, and a foamed space may be formed between the liner and the housing 1. By filling the foamed space with foam material, a good heat preservation effect can be achieved for the refrigeration chamber.

[0038] like Figure 1 As shown, in some embodiments, the refrigeration device may include a door 13. The door 13 is movably mounted on the housing 1 and is used to open or close the refrigeration compartment.

[0039] Multiple doors 13 can be provided, and multiple doors 13 can be correspondingly provided on multiple refrigeration compartments. The doors can be movably provided on the cabinet 1 by means of rotation or sliding.

[0040] In some embodiments, the refrigeration system includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the cabinet 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.

[0041] In some embodiments, the refrigeration system includes a compressor (not shown). The compressor is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] Figure 2 for Figure 1 A schematic diagram from another perspective.

[0047] like Figure 2 As shown, in some embodiments, a first extension 11 and a second extension 12 can be respectively provided on the left and right sides above the top wall of the cabinet 1. The first extension 11 and the second extension 12 are arranged at intervals and form an installation space at the intervals. In this way, by arranging the first extension 11 and the second extension 12 extending upward from the top wall of the cabinet 1, the overall appearance of the refrigerator is better and more beautiful.

[0048] In some embodiments, the cooling device may include a light box 2, which is located above the housing 1 and between the first extension 11 and the second extension 12. The light box 2 is arranged in the installation space formed between the first extension 11 and the second extension 12.

[0049] The cooling device may include a lampshade 3, which is located on the front side of the light box 2, and a lamp assembly 4 is installed inside the lampshade 3. The side wall of the lampshade 3 may be provided with a light-transmitting part (not shown in the figure). By placing the lampshade 3 on the front side of the light box 2, when the lamp assembly 4 is working, the light source of the lamp assembly 4 can shine through the light-transmitting part to the outside of the lampshade 3, thereby playing the role of lighting and display advertising.

[0050] The light box 2 includes a top plate 21 and side plates 22. The top plate 21 can be installed on the top wall of the refrigeration unit. The side plates 22 can be installed below the top plate 21, extending downward from the peripheral edge of the top plate 21. The side plates 22 and the top plate 21 are integrally injection molded. The left and right side walls of the side plates 22 are limited between the first extension 11 and the second extension 12. The bottom of the side plates 22 is supported and fixed to the top wall of the box body 1.

[0051] Specifically, the top plate 21 and the side plates 22 of the light box 2 are integrally injection molded, rather than by cutting and splicing sheet metal parts. The injection molding of the light box 2 is completed in one step by a mold, resulting in smooth and flat edges on the finished product, avoiding the burrs and sharp edges commonly found after cutting sheet metal parts. Moreover, the top plate 21 and the side plates 22 of the light box 2 form an integral injection molded structure similar to a box or lid, creating a rigid support frame. The top plate 21 is located on the top wall of the refrigeration unit. When the top is subjected to gravity or other pressure, the pressure on the top plate 21 can be transmitted downwards and outwards through the side plates 22. The side plates 22, as a vertical support frame, distribute the pressure to the top wall of the box 1, thereby effectively improving the overall structural strength of the light box 2 and significantly enhancing its pressure resistance.

[0052] In related technologies, since the lightbox 2 is made of multiple sheet metal parts, these parts are processed through stamping and cutting, resulting in uneven burrs on the edges and gaps at the joints. Furthermore, during the integral foaming process of the first extension 11 and the second extension 12 extending upwards from the top of the box 1 with the internal foam layer of the box 1, the first extension 11 and the second extension 12 are prone to deformation. When connecting the sheet metal lightbox 2 to the first extension 11 and the second extension 12 on both sides using screws, misalignment of the connection holes can easily occur, increasing installation difficulty. Additionally, the joints between the sheet metal parts and the first extension 11 and the second extension 12 are weak, making them susceptible to warping and misalignment under slight external force. On the other hand, refrigeration units may be subjected to trampling weight during warehouse storage and transportation, and their tops are also used for placing heavy objects in the retail industry.

[0053] In the technical solution of this application, by integrally injection molding the top plate 21 and the peripheral side plate 22 of the light box 2, and molding it in one step with a high-precision mold, the finished edge of the light box 2 is smooth and flat without any sharp edges or burrs, and can easily achieve beautiful shapes such as rounded corners and curved surfaces. Moreover, the overall structure of the light box 2 has no splicing gaps. The integral injection molded box structure formed by the top plate 21 and the peripheral side plate 22 is a continuous whole. When the top wall of the refrigeration device is subjected to force, the stress can be dispersed and transmitted along the integral structure of the top plate 21 and the peripheral side plate 22, dispersing the pressure to the top wall of the box 1, and greatly improving the overall pressure resistance. Regarding the installation of the light box 2, it is embedded between the first extension 11 and the second extension 12. During installation, simply insert the left and right sides of the side panel 22 of the light box 2 from top to bottom along the first extension 11 and the second extension 12. There is no need to manually adjust the left and right position of the light box 2. Then, fix the light box 2 to the top of the housing 1. Compared with the light box 2 structure formed by sheet metal parts, it eliminates the need for multiple manual adjustments to align the holes between the sheet metal parts and the first extension 11 and the second extension 12, reducing installation difficulty and effectively improving installation efficiency. Furthermore, the light box 2 is embedded inside the first extension 11 and the second extension 12, which extend upwards from both sides of the housing 1, making the appearance of the refrigeration device more integrated and improving the overall aesthetics of the refrigeration device.

[0054] Figure 3 for Figure 2 A schematic diagram showing the integral connection between the middle box body and the first extension and the second extension.

[0055] like Figure 3 As shown, in some embodiments, the top plate 21 and the top walls of the first extension 11 and the second extension 12 can be flush, and the top of the top plate 21 and the top of the first extension 11 and the second extension 12 constitute the top wall of the refrigeration device. In this way, the integrated injection-molded light box 2 can be effectively supported on the top of the refrigeration device, improving the structural strength of the top of the refrigeration device and helping to distribute the weight of the top during use and transportation.

[0056] In some embodiments, the left and right opposite sides of the light box 2 are respectively fitted with the first extension 11 and the second extension 12 with clearance. Similarly, the opposite sides of the peripheral side plate 22 are respectively fitted with the first extension and the second extension 12 with clearance.

[0057] Since the first extension and the second extension 12 are integrally foamed with the housing 1, the foam material will naturally shrink during the curing process, causing the actual size of the first extension and the second extension 12 to deviate from the design size. By fitting the left and right opposite sides of the light box 2 with the first extension 11 and the second extension 12 respectively with a gap, the size deviation caused by the shrinkage of the foam material can be accommodated. At the same time, the limiting function of the first extension 11 and the second extension 12 on the light box 2 can be ensured, and the stability of the installation position of the light box 2 can be maintained.

[0058] like Figure 3 As shown, in some embodiments, the first extension 11 may include a first extension wall 111, a second extension wall 112, and a first connecting wall 113. The first extension wall 111 may extend upward from the left side wall of the housing 1 and protrude above the top wall of the housing 1. The second extension wall 112 may extend upward from the left side of the top wall of the housing 1. The first extension wall 111 and the second extension wall 112 may be arranged with relative spacing. The first connecting wall 113 may be connected to the top of the first extension wall 111 and the second extension wall 112. The first extension 11 is provided with a first foaming cavity 101, which is formed between the first extension wall 111, the second extension wall 112, and the first connecting wall 113. Thus, the first foaming cavity 101 can be integrally formed with the foaming layer of the housing 1.

[0059] By integrally extending a first extension 11 to the top of the housing 1, and foaming the first extension 11 integrally with the housing 1, gaps between the first extension 11 and the housing 1 can be avoided, improving the aesthetics of the refrigeration device. Furthermore, the top of the first extension 11 can form the top wall of the refrigeration device with the top plate 21 of the light box 2. When the top of the refrigeration device supports heavy objects or bears gravity during transportation, the integral foaming of the first extension 11 and the housing 1 can improve the structural strength of the top of the refrigeration device, meeting the user's need to place heavy objects on top.

[0060] In some embodiments, the first extension 11 may include a first front extension plate 114 and a first rear extension plate (not shown in the figures). The first front extension plate 114 may be connected between the front sides of the first extension wall 111 and the second extension wall 112, and the first rear extension plate may be connected between the rear sides of the first extension wall 111 and the second extension wall 112. A first foaming cavity 101 is formed between the first extension wall 111, the second extension wall 112, the first connecting wall 113, the first front extension plate 114, and the first rear extension plate.

[0061] The first connecting wall 113, which serves as the top wall of the first extension 11, can be connected by the portion of the top of the first extension wall 111 that bends toward the side of the second extension wall 112, and the portion of the top of the second extension wall 112 that bends toward the side of the first extension wall 111.

[0062] In some embodiments, the second extension 12 may include a third extension wall 121, a fourth extension wall 122, and a second connecting wall 123. The second extension 12 extends upward from the right side wall of the housing 1 and protrudes above the top wall of the housing 1. The fourth extension wall 122 extends upward from the right side of the top wall of the housing 1. The third extension wall 121 and the fourth extension wall 122 may be arranged with relative spacing. The second connecting wall 123 may be connected to the top of the third extension wall 121 and the fourth extension wall 122. The second extension 12 is provided with a second foaming cavity 102, which is formed between the third extension wall 121, the fourth extension wall 122, and the second connecting wall 123. Thus, the second foaming cavity 102 can be integrally formed with the foaming layer of the housing 1.

[0063] By integrally extending a second extension 12 to the top of the housing 1, and foaming the second extension 12 integrally with the housing 1, gaps between the second extension 12 and the housing 1 can be avoided, improving the aesthetics of the refrigeration device. Furthermore, the top of the second extension 12 can form the top wall of the refrigeration device with the top plate 21 of the light box 2, or the top of the first extension 11, the top plate 21 of the light box 2, and the top of the second extension 12 can form the top wall of the refrigeration device. When the top of the refrigeration device supports heavy objects or bears gravity during transportation, the integral foaming of the second extension 12 with the housing 1 can improve the structural strength of the top of the refrigeration device, meeting the user's need to place heavy objects on top.

[0064] In some embodiments, the second extension 12 may include a second front extension plate 124 and a second rear extension plate (not shown). The second front extension plate 124 may be connected between the front sides of the third extension wall 121 and the fourth extension wall 122, and the second rear extension plate may be connected between the rear sides of the third extension wall 121 and the fourth extension wall 122. A second foaming cavity 102 is formed between the third extension wall 121, the fourth extension wall 122, the second connecting wall 123, the second front extension plate 124, and the second rear extension plate.

[0065] The second connecting wall 123, which serves as the top wall of the second extension 12, can be connected to the portion of the top of the third extension wall 121 that bends toward the side of the fourth extension wall 122, and the portion of the top of the fourth extension wall 122 that bends toward the side of the third extension wall 121.

[0066] Figure 4 for Figure 1 A schematic diagram of the central lightbox; Figure 5 for Figure 4 A schematic diagram from another perspective.

[0067] like Figure 4 and Figure 5As shown, in some embodiments, the top plate 21 and the peripheral side plate 22 can be enclosed to form a receiving cavity 201. The bottom of the peripheral side plate 22 forms a box opening 202 communicating with the receiving cavity 201, and the top wall of the box body 1 can close the box opening 202. Specifically, when the light box 2 is installed between the first extension 11 and the second extension 12, the edge of the peripheral side plate 22 is fitted against the top wall of the box body 1, and the top wall of the box body 1 seals the box opening 202 of the light box 2, thereby forming a sealed receiving cavity 201. The receiving cavity 201 is used to accommodate the electrical control part of the lamp assembly 4.

[0068] Specifically, the cavity 201 formed by the top plate 21 and the peripheral side plates 22 provides an integrated installation area for the electrical control components. The electrical control components of the lamp assembly 4 may include electrical connection wires, control boxes, or power supply modules. Before installing the light box 2, the electrical control components of the lamp assembly 4 are pre-installed between the first extension 11 and the second extension 12. Then, the entire light box 2 is placed on top of the housing 1. The opening 202 at the bottom of the peripheral side plates 22 is sealed by the top wall of the housing 1, preventing the electrical control components of the lamp assembly 4 from being installed separately or exposed to other environments, thus improving the protection of the electrical control components. On the other hand, the top plate 21 and the peripheral side plates 22 of the light box 2 provide a rigid protective shell for the electrical control components. When the top of the light box 2 is subjected to pressure, the top plate 21 and the peripheral side plates 22 can directly withstand the external force, preventing the electrical control components from being crushed and damaged.

[0069] In some embodiments, the side wall of the lampshade 3 may be provided with a notch (not shown in the figure), and the electrical connection wire of the lamp assembly 4 can be arranged in the foam space of the housing 1 through the notch, and then pass through the top of the housing 1 and arranged between the first extension 11 and the second extension 12.

[0070] like Figure 5 As shown, in some embodiments, the light box 2 may include a reinforcing rib 24, which may be integrally connected to the top plate 21 or integrally connected to the peripheral side plate 22, or one end of the reinforcing rib 24 may be connected to the top plate 21 and the other end of the reinforcing rib may be connected to the peripheral side plate 22.

[0071] Multiple reinforcing ribs 24 can be provided, and multiple reinforcing ribs 24 can be arranged at intervals on the inner side wall of the light box 2, thereby improving the overall structural strength of the light box 2.

[0072] like Figure 2 and Figure 5 As shown, in some embodiments, the light box 2 may include a fixing plate 23. The fixing plate 23 is bent and extended from the bottom of the peripheral side plate 22 toward the outside of the light box 2. The fixing plate 23 can be attached and fixed to the top wall of the box body 1. The light box 2 can be fixedly connected to the outer wall of the box body 1 through the fixing plate 23.

[0073] The fixing plate 23 extends outward from the bottom of the peripheral side plate 22, forming a plate-like structure parallel to the top wall of the housing 1. The fixing plate 23 serves as the connection structure between the light box 2 and the housing 1. By attaching and fixing the fixing plate 23 to the top wall of the housing 1, the contact area between the fixing plate 23 and the top wall of the housing 1 can be increased. Specifically, the fixing plate 23 may be provided with fixing holes 205. During installation, the operator can insert the connector into the fixing holes 205 to fix the fixing plate 23 to the housing 1. When the light box 2 is subjected to force, the stress can be evenly transmitted to the housing 1 through the entire fixing plate 23.

[0074] On the other hand, by providing a fixing plate 23 at the bottom of the side plate 22, the operator can directly connect to the top of the box 1 through the fixing plate 23. Compared with the existing scheme of using multiple sheet metal parts to form the structure of the light box 2 on the top of the box 1, there is no need to use screws, bolts and other connecting parts to connect one by one with the multiple connecting holes on the first extension 11 and the second extension 12. This can avoid the need for manual adjustment of the connection position due to the shrinkage and deformation of the box 1 after foaming, which would make the installation complicated and cumbersome and could easily cause appearance problems of the refrigeration device. The installation process of the light box 2 is more convenient.

[0075] The fixing plate 23 can be disposed at the rear end of the peripheral side plate 22 and extend from the bottom of the rear end of the peripheral side plate 22 toward the rear side of the light box 2. It should be noted that in some other embodiments, the fixing plate 23 can be disposed at other positions of the peripheral side plate 22. For example, the fixing plate 23 can be arranged to extend outward from the bottom of the peripheral side plate 22 near the first extension 11, or the fixing plate 23 can be arranged to extend outward from the bottom of the peripheral side plate 22 near the second extension 12.

[0076] In some embodiments, the fixing plate 23 and the peripheral side plate 22 can be integrally injection molded.

[0077] Specifically, the fixing plate 23 and the peripheral side plate 22 are integrally injection molded, so that there are no welding or splicing gaps in the overall structure of the light box 2. The material continuity of the overall structure of the light box 2 is good, which can effectively avoid stress fracture at the fixing position of the light box 2 and the box body 1, and improve the structural strength and deformation resistance of the light box 2.

[0078] like Figure 2 and Figure 5 As shown, in some embodiments, a clearance groove 203 may be formed on the outer side of the rear sidewall of the peripheral side plate 22. The rear sidewall of the peripheral side plate 22 may be recessed towards the front, and a clearance groove 203 may be formed on the outer side of the rear sidewall. The clearance groove 203 may be formed between the first extension 11 and the second extension 12, thereby making full use of the top space of the refrigeration device. The fixing plate 23 is located at the bottom of the clearance groove 203.

[0079] Specifically, the fixing plate 23 is located at the bottom of the clearance groove 203 to prevent the fixing plate 23 from extending outward to the top outside of the box 1 and thus occupying too much horizontal space of the box 1. While ensuring the fixed area of ​​the fixing plate 23 and the top of the box 1, it can also improve the utilization rate of the top space of the box 1, making the structure of the light box 2 more compact.

[0080] In some embodiments, at least two clearance grooves 203 may be formed on the outer side of the rear sidewall of the peripheral side plate 22. The two clearance grooves 203 may be arranged at intervals along the left and right direction of the housing 1. Correspondingly, at least two fixing plates 23 are provided, and the fixing part is provided at the bottom of the clearance groove 203. In this way, when the light box 2 is subjected to force, its stress can be evenly transmitted to the top wall of the housing 1 through at least two fixing plates 23, avoiding the loosening of screws or deformation of the plate surface of a single fixing plate 23 due to long-term bearing of the full weight.

[0081] Figure 6 for Figure 1 A cross-sectional view; Figure 7 for Figure 6 A partial exploded view.

[0082] like Figure 6 and Figure 7 As shown, in some embodiments, the lampshade 3 is a cover with an opening at the rear. The cooling device may include a reinforcing plate 5, which is disposed at the rear opening of the lampshade 3. The reinforcing plate 5 may extend along the length of the lampshade 3, and the front side of the reinforcing plate 5 and the lampshade 3 enclose a lamp cavity 301. The reinforcing plate 5 may be fixedly connected to the front sidewall of the peripheral plate 22. The lamp assembly 4 is disposed within the lamp cavity 301 and fixedly connected to the reinforcing plate 5.

[0083] By fixing the reinforcing plate 5 to the front side wall of the peripheral side plate 22, a stable mounting base can be provided for the lamp assembly 4. The lamp assembly 4 is mounted on the reinforcing plate 5, which allows the lamp assembly 4 to be firmly installed on the light box 2, avoiding problems such as unstable lighting or poor contact caused by the shaking of the lamp assembly 4, and improving the reliability and stability of the lamp assembly 4. Moreover, by placing the reinforcing plate 5 at the rear opening of the lamp cover 3, the reinforcing plate 5 and the lamp cover 3 enclose the lamp cavity 301. During the transportation or use of the refrigeration unit, the top of the lamp cover 3 may be subjected to various external forces. By connecting the reinforcing plate 5 to the lamp cover 3, the reinforcing plate 5 can effectively disperse the external forces on the lamp cover 3 and transfer them to the light box 2, preventing the lamp cover 3 from deforming or being damaged. This is beneficial to the normal operation of the lamp assembly 4 and the overall appearance integrity of the refrigerator.

[0084] like Figure 7 As shown, in some embodiments, the cooling device may further include a connector 6, which may be inserted through the lamp assembly 4 and the reinforcing plate 5, thereby fixing the lamp assembly 4 to the reinforcing plate 5.

[0085] like Figure 6 As shown, in some embodiments, the reinforcing plate 5 is snapped and fixed to the light box 2.

[0086] In some embodiments, the front sidewall of the peripheral side plate 22 may be provided with a buckle 221, and the reinforcing plate 5 may be provided with a slot 501 corresponding to the buckle 221. The buckle 221 is aligned and engaged in the slot 501, so that the front sidewall of the peripheral side plate 22 is fixedly connected to the back of the reinforcing plate 5. It should be noted that in some other embodiments, the front sidewall of the peripheral side plate 22 may be provided with a slot 501, and the reinforcing plate 5 may be provided with a buckle 221 corresponding to the slot 501. The buckle 221 is aligned and engaged in the slot 501.

[0087] To further simplify the installation structure of the light box 2, a snap-fit ​​221 is provided on the front side wall of the peripheral side plate 22, and a corresponding slot 501 is provided on the reinforcing plate 5. The snap-fit ​​221 is aligned and snapped into the slot 501, thus achieving a fixed connection between the front side wall of the peripheral side plate 22 and the back of the reinforcing plate 5. This snap-fit ​​connection eliminates the need for screws or other additional fasteners, as well as complex tools and operating procedures, greatly simplifying the installation process and significantly improving production and installation efficiency. Correspondingly, the matching design of the snap-fit ​​221 and the slot 501 also makes the assembly and disassembly of the reinforcing plate 5 and the peripheral side plate 22 very convenient. When subsequent maintenance, replacement, or adjustment of the light box 2 components is required, operators can easily remove the reinforcing plate 5.

[0088] Figure 8 for Figure 1 Exploded view of another embodiment; Figure 9 for Figure 8 Another diagram illustrating an explosion; Figure 10 for Figure 8 A partial exploded view.

[0089] like Figure 8 , Figure 9 and Figure 10 As shown, in some other embodiments, the lampshade 3 can be a cover with a rear opening, and the rear edge of the lampshade 3 can be fixed to the front wall of the peripheral side plate 22; the interior of the lampshade 3 and the front wall of the peripheral side plate 22 enclose to form a lamp cavity 301. The lamp assembly 4 is disposed in the lamp cavity 301 and fixedly connected to the front wall of the peripheral side plate 22.

[0090] To further improve installation efficiency and reduce installation difficulty, the lamp assembly 4 can be directly fixed to the front wall of the peripheral side plate 22 of the light box 2. Since the light box 2 is integrally injection molded from the top plate 21 and the peripheral side plate 22, it has good structural strength. Thus, the structure and function of the reinforcing plate 5 can also be integrated into the light box 2. The reinforcing plate 5, as an additional component, needs to be purchased and installed separately. Integrating the reinforcing plate 5 into the light box 2 reduces the number of components in the cooling unit, resulting in a simpler structure and reducing assembly errors that might result from too many components. Furthermore, operators do not need to install the reinforcing plate 5 first and then connect the lamp assembly 4 to the reinforcing plate 5, reducing installation steps and operational difficulty.

[0091] Figure 11 for Figure 8 A schematic diagram of the central lightbox; Figure 12 for Figure 8 Partial cross-sectional view; Figure 13 for Figure 8 A partial schematic diagram.

[0092] like Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, a connecting rib 223 may be provided on the front wall of the peripheral side plate 22. The connecting rib 223 extends into the lamp cavity 301 and is provided with a slot 204. A buckle 31 is provided on the rear edge of the lamp cover 3, and the buckle 31 is inserted into the slot 204.

[0093] Specifically, the connecting rib 223 extends into the lamp cavity 301, providing additional support for the connection between the lampshade 3 and the peripheral side plate 22. The slot 204 on the connecting rib 223 corresponds to the snap fastener 31 on the rear edge of the lampshade 3. During installation, the snap fastener 31 can be accurately inserted into the slot 204, forming a tight connection between the lampshade 3 and the peripheral side plate 22, further improving the stability of the connection. Regarding ease of installation, the connection between the lamp box 2 and the lampshade 3 uses the snap fastener 31 and slot 204, eliminating the need for additional tools and complex procedures. Operators simply align the snap fastener 31 on the rear edge of the lampshade 3 with the slot 204 on the connecting rib 223 and insert it to complete the installation. This snap-fit ​​installation method significantly shortens installation time and improves production efficiency.

[0094] Furthermore, the insertion method of the buckle 31 and the slot 204 is more discreet in appearance, and will not leave obvious marks on the surface of the lampshade 3 like screws and other connection methods. This makes the connection between the lampshade 3 and the side panel 22 more natural and smooth, and the overall appearance is cleaner and more beautiful.

[0095] It should be noted that, in order to further improve the connection strength between the light box 2 and the lampshade 3, a screw connection can be added between the light box 2 and the lampshade 3.

[0096] like Figure 13 As shown, to facilitate the connection structure between the display light assembly and the side panel, Figure 11 This is a structural diagram showing the cooling device concealed behind a light box. In some embodiments, the peripheral side plate 22 and the light assembly 4 can be fixed together by snap-fit.

[0097] like Figure 11 and Figure 13 As shown, in some embodiments, a limiting buckle 222 may be provided on the front wall of the peripheral side plate 22. Two limiting buckles 222 may be provided, arranged vertically opposite each other. The upper and lower sides of the lamp assembly 4 are respectively engaged with the limiting buckles 222. By providing two vertically opposite limiting buckles 222, the upper and lower sides of the lamp assembly 4 are engaged with the limiting buckles 222, which can limit the height of the lamp assembly 4. This controls the position of the lamp assembly 4 in the vertical direction of the light box 2, ensuring that the lamp assembly 4 is at the correct vertical height after installation, avoiding problems such as poor lighting effect or interference with other components due to installation position deviations.

[0098] In some embodiments, the limiting buckle 222 and the peripheral side plate 22 are integrally injection molded. This integral injection molding of the limiting buckle 222 and the peripheral side plate 22 creates an integral structure, which improves the structural strength and stability of the limiting buckle 222, enabling it to withstand greater external forces and reducing the likelihood of breakage or deformation. Furthermore, the limiting buckle 222 is made of plastic, giving it excellent electrical insulation properties, effectively blocking current conduction between the lamp assembly 4 and external structures, thus meeting the electrical connection protection requirements of the lamp assembly 4.

[0099] like Figure 12 As shown, in some embodiments, the lamp assembly 4 may be provided with a limiting hole 401. The front wall of the peripheral side plate 22 may be provided with positioning posts 224, which are spaced apart on one side of the limiting buckle 222 and are correspondingly inserted into the limiting hole 401.

[0100] The corresponding insertion of the positioning post 224 and the limiting hole 401 not only serves as a pre-positioning mechanism for the connection between the lamp assembly 4 and the peripheral side plate 22, but also provides double fixation in conjunction with the snap-fit ​​of the limiting buckle 222. Specifically, the limiting buckle 222 snaps and fixes the lamp assembly 4 from the vertical direction to prevent the lamp assembly 4 from loosening or falling off in the vertical direction, while the insertion of the positioning post 224 and the limiting hole 401 positions and fixes the lamp assembly 4 from the horizontal direction to prevent the lamp assembly 4 from moving in the horizontal direction. This can greatly improve the stability of the lamp assembly 4 installation and is conducive to preventing the lamp assembly 4 from being displaced or damaged due to vibration, collision or other reasons during the transportation and use of the refrigerator.

[0101] In some embodiments, two positioning posts 224 may be provided, and the two positioning posts 224 may be provided on the left and right sides of the limiting buckle 222. During the installation process, the limiting hole 401 on the lamp assembly 4 may be inserted into the corresponding positioning post 224 first, and then the lamp assembly 4 may be snapped into the limiting buckle 222, thereby completing the installation process of the lamp assembly 4 and the lamp box 2.

[0102] 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.
