[0051] In some embodiments of the present application, multiple storage compartments 112 may be arranged in a left-and-right partitioned manner.

[0052] In some embodiments of the present application, the cabinet 1 may be provided with an inner liner 11. The inner liner 11 is disposed within the housing 12. The interior of the inner liner 11 is hollow. The storage compartment 112 is formed within the inner liner 11. A pick-up opening 111 is formed on the front side of the inner liner 11. Items can be placed into the corresponding storage compartment 112 through the pick-up opening 111. It can be understood that multiple inner liners 11 may be provided within the cabinet 1.

[0053] Please refer to Figure 1 , in some embodiments of the present application, the cabinet 1 may include a door 4. The door 4 is movably disposed on the front side of the cabinet 1. The door 4 is configured to be able to enclose the inner liner 11, so that the interior of the inner liner 11 is thermally insulated from the outside.

[0054] In some embodiments of the present application, the door 4 may be a rotary door structure. The door 4 is rotatably connected to one side of the cabinet 1 where the pick-up opening 111 is provided. At this time, the door 4 can be used as a common door structure, such as a refrigeration door, a freezing door, etc.

[0055] Specifically, the door 4 and the cabinet 1 may be connected by a hinge, so that the door 4 of the refrigerator can rotate around the axis of the hinge, realizing the opening and closing of the door 4 of the refrigerator, and further opening and closing the corresponding storage compartment 112.

[0056] In some embodiments of the present application, the door 4 may also be a push-pull door structure.

[0060] In some embodiments of the present application, the air duct assembly may include a fan (not shown in the figure). The fan is used to accelerate the air flow velocity between the entire air duct assembly and the inner box 11, thereby accelerating heat exchange and promoting the cooling efficiency.

Figure 5 It is a schematic connection structure diagram between the surface light source assembly and the shelf assembly provided by the present application.

[0062] As Figures 2 to 4 shown, in some embodiments of the present application, a shelf assembly 2 may be provided in the inner box 11 to form a shelf space for storing items.

[0063] The shelf assembly 2 may be detachably provided in the inner box 11.

[0064] In some embodiments of the present application, the shelf assembly 2 may include a shelf board 22. The shelf board 22 is used for storing items.

[0065] As Figure 5 shown, in some embodiments of the present application, the shelf assembly 2 may include a shelf board 22 sheath 21. The shelf board 22 sheath 21 is disposed on the outer periphery of the shelf assembly 2. The shelf board 22 sheath 21 is disposed on the outer periphery of the shelf board 22, which can prevent the shelf board 22 from being damaged by collision.

[0066] The shelf assembly 2 may include a mounting bracket 23. The mounting bracket 23 is fixed to the side wall of the inner box 11 away from the access opening 111 and extends towards the access opening 111. The left and right sides of the shelf board 22 are supported on the mounting bracket 23.

[0067] Figure 6 For Figure 3 The enlarged view of part C in Figure 7 For Figure 4 The enlarged view of part E in

[0068] As Figure 4 , Figure 6 And Figure 7As shown, in some embodiments of the present application, the mounting rack 23 may include a first mounting rack 231 and a second mounting rack 232. The first mounting rack 231 is fixed to the side wall of the box 11 away from the access port 111. A plurality of mounting holes 233 are provided on the first mounting rack 231. The plurality of mounting holes 233 are distributed along the height direction of the first mounting rack 231. The second mounting rack 232 is snapped into the mounting holes 233 of the first mounting rack 231. The second mounting rack 232 can be connected to the mounting holes 233 at different heights to change the distance between adjacently arranged layer boards 22, thereby changing the layer shelf space to accommodate the placement of items of different sizes.

[0069] like Figures 2 to 4 , Figure 6 As shown, in some embodiments of the present application, a surface light source assembly 3 may also be provided in the box 11. The surface light source assembly 3 can be used for lighting in the box 11 to improve the user experience of the refrigerator. The surface light source assembly 3 can be arranged in parallel with the shelf assembly 2. The surface light source assembly 3 is detachably arranged below the shelf assembly 2. The surface light source assembly 3 can provide uniform and soft light, reduce the intensity difference of the light, so that the light emitted by the surface light source assembly 3 can be more reliably and evenly irradiated to all parts of the shelf assembly 2, thereby improving the lighting effect in the box 11. The surface light source assembly 3 is a consumable, and its service life will be shorter than that of the refrigerator. The surface light source assembly 3 is detachably connected to the shelf assembly 2, which is more convenient for the maintenance and replacement of the surface light source assembly 3. In addition, no objects need to be placed on the surface light source assembly 3, so that the surface light source assembly 3 has a larger heat dissipation area, thereby improving the heat dissipation effect.

[0070] In some embodiments of the present application, the surface light source assembly 3 may be of a thin plate-like design, which is easy to install and does not occupy much shelf space.

[0071] It is understandable that the area of ​​the surface light source assembly 3 that can scatter light can be adjusted to meet different lighting brightness requirements.

[0072] In some embodiments of the present application, a gap may be provided between the surface light source assembly 3 and the shelf assembly 2 , so that the heat dissipation area of ​​the surface light source assembly 3 can be increased, thereby improving the heat dissipation effect of the surface light source assembly 3 .

[0073] like Figure 2As shown, in some embodiments of the present application, the laminate 22 can be configured to allow light to pass through. That is, the laminate 22 can be configured as a transparent plate. The laminate 22 can also be configured as a translucent plate. Further, the laminate 22 can be made of a glass plate, which has a high transparency and a certain hardness, and can meet the requirements for placing general items. The surface light source assembly 3 is a surface light source assembly 3 that emits light on both sides, and can emit light upward and downward. That is, the light generated by the surface light source assembly 3 can pass upward through the laminate 22 to illuminate the upper shelf space; and the light generated by the surface light source assembly 3 can illuminate the lower shelf space downward, improving the lighting effect of the surface light source assembly 3.

[0074] It can be understood that when multiple shelf assemblies 2 are provided in the box liner 11, the surface light source assembly 3 can be provided below one of the laminates 22; or the surface light source assemblies 3 can be respectively provided below multiple laminates 22 to improve the lighting effect in the box liner 11.

[0075] Figure 8 It is a schematic structural diagram of the surface light source assembly provided by the present application under the first visual angle; Figure 9 It is a schematic structural diagram of the support frame provided by the present application.

[0076] As Figure 8 and Figure 9 shown, in some embodiments of the present application, the surface light source assembly 3 can include a support frame 33. The support frame 33 can be made of aluminum alloy. The aluminum alloy has a light weight, which can reduce the weight of the surface light source assembly 3 to a certain extent, thereby improving its installation stability. At the same time, the support frame 33 made of aluminum alloy also has good oxidation resistance and is not easy to rust and be corroded in the humid environment inside the refrigerator. The support frame 33 made of aluminum alloy also has a high strength, which can effectively protect other parts of the surface light source assembly 3 supported by it from being damaged by external collisions. In addition, the support frame 33 made of aluminum alloy also has good heat dissipation performance, thereby improving the heat dissipation of the surface light source assembly 3.

[0077] In some embodiments of the present application, the support frame 33 is configured as a rectangular frame. It can be understood that in other embodiments, the support frame 33 can also be configured in other shapes. An installation groove 331 can be formed inside the support frame 33. The opening of the installation groove 331 faces the inside of the support frame 33.

[0078] Figure 10 It is a schematic structural diagram of the surface light source assembly provided by the present application under the second visual angle; Figure 11 is Figure 10 a cross-sectional view along the B-B direction; Figure 12 is Figure 11 an enlarged view of part F in Figure 13Schematic cross-sectional structure diagram of the surface light source assembly provided by another embodiment of the present application. Figure 14 Schematic cross-sectional structure diagram of the surface light source assembly provided by yet another embodiment of the present application.

[0079] As Figures 10 to 14 shown, in some embodiments of the present application, the surface light source assembly 3 may further include a light guide plate 34. The light guide plate 34 is disposed inside the support frame 33. It can be understood that mounting grooves 331 are provided on all four sides of the support frame 33, and the four peripheral edges of the light guide plate 34 are inserted into the mounting grooves 331. The light guide plate 34 is arranged in parallel with the shelf assembly 2. The light guide plate 34 is arranged in parallel with the shelf board 22. The light guide plate 34 can improve the uniformity of the light emitted by the light source, enhance the brightness and visual effect of the surface light source assembly 3, and avoid the situation of too high or too low local brightness in the shelf space.

[0080] In some embodiments of the present application, the support frame 33 may include support bars (not shown in the figure). There are four support bars configured. The four support bars are respectively disposed around the support frame 33 and enclose to form the support frame 33. That is, the four support bars are respectively located on the four sides of the rectangular frame. The inner side of the support bars forms the above-mentioned mounting grooves 331.

[0081] As Figures 12 to 14 shown, in some embodiments of the present application, the surface light source assembly 3 may include an LED light bar 35. The LED light bar 35 has a high brightness and can improve the lighting effect of the surface light source assembly 3; and the LED light bar 35 has a long service life and can reduce the frequency of replacement and repair of the surface light source assembly. The LED light bar 35 is disposed in the mounting groove 331. The LED light bar 35 can emit light toward the notch direction of the mounting groove 331. The light emitted by the LED light bar 35 passes through the light guide plate 34, and can transmit the light to the entire upper surface and lower surface of the surface light source assembly 3, so that the light can be evenly diffused into the shelf space.

[0082] In some embodiments of the present application, the surface light source assembly 3 may include a diffusion layer 37. The diffusion layer 37 may be disposed inside the support frame 33. The four sides of the diffusion layer 37 are respectively inserted into the mounting grooves 331. The diffusion layer 37 is respectively disposed above and below the light guide plate 34. The diffusion layer 37 can diffuse the light transmitted through the light guide plate 34, so that the light is more evenly distributed on the surface of the entire surface light source assembly 3, and avoid the situation of uneven light.

[0083] As Figure 14As shown, in some embodiments of the present application, the surface light source assembly 3 may further include a reflective layer 36. The reflective layer 36 is disposed above the light guide plate 34. The reflective layer 36 is disposed between the light guide plate 34 and the diffusion layer 37. The reflective layer 36 does not cover the entire surface of the light guide plate 34, so that light can irradiate from the light guide plate 34 into the diffusion layer 37. The reflective layer 36 can reflect the light emitted by the LED light bar 35 multiple times inside the surface light source, thereby improving the light efficiency and enhancing the lighting effect. It can be understood that, in some other embodiments, the reflective layer 36 may also be disposed below the light guide plate 34, between the light guide plate 34 and the diffusion layer 37. In some other embodiments, the reflective layer 36 may be disposed above and below the light guide plate 34, between the light guide plate 34 and the diffusion layer 37.

[0084] As Figure 12 and Figure 14 shown, in some embodiments of the present application, a protective layer 38 may be disposed outside the light guide plate 34. The protective layer 38 is made of a material that can transmit light. The outer surface of the protective layer 38 is flush with the surface of the support frame 33. The protective layer 38 can prevent the light guide plate 34 from being damaged by collision and can improve the moisture resistance of the surface light source assembly 3.

[0085] As Figure 10 shown, in some embodiments of the present application, the refrigerator may include a controller (not shown in the figure). The surface light source assembly 3 may include a wire 39, and the electrical connection between the LED light bar 35 and the controller is realized through the wire 39.

[0086] A through hole (not shown in the figure) may be provided on the support frame 33. The LED light bar 35 may include an LED light source and a PCB board. The LED light source is electrically connected to the PCB board. The wire 39 passes through the through hole and is connected to the PCB board to realize the electrical connection and signal conduction of the LED light source. The connection between the wire 39 and the through hole is sealed with UV glue to enhance the moisture resistance of the surface light source assembly 3 and prevent condensation.

[0087] As Figure 10 shown, in some embodiments of the present application, the surface light source assembly 3 may include a connector 310. The wire 39 is respectively connected to the LED light bar 35 and the connector 310, and the quick connection between the wire 39 and the controller is realized through the connector 310. The protection level of the connector 310 is not less than IP67. That is, the connector 310 can completely block dust from entering and can maintain normal operation under short-term immersion in water. The connection between the wire 39 and the connector 310 is sealed with UV glue to improve the waterproof performance and ensure the effectiveness of the connection between the surface light source assembly 3 and the controller.

[0088] As Figure 5As shown, in some embodiments of the present application, the surface light source assembly 3 may include a connecting member 31, and the surface light source assembly 3 is connected to the shelf assembly 2 through the connecting member 31. By loosening the connection between the connecting member 31 and the surface light source assembly 3, the surface light source assembly 3 can be disassembled to achieve the repair and replacement of the surface light source assembly 3.

[0089] In some embodiments of the present application, the surface light source assembly 3 may include a surface light source sheath 32. The surface light source sheaths 32 are respectively arranged on one side of the surface light source assembly 3 close to the pick-and-place opening 111 and on one side away from the pick-and-place opening 111, which can to a certain extent prevent the surface light source assembly 3 from being damaged by collision.

[0090] In some embodiments of the present application, a first connection hole (not shown in the figure) may be provided on the surface light source assembly 3. Multiple first connection holes may be provided. The multiple first connection holes may be arranged on opposite sides of the surface light source assembly 3. Or, the multiple first connection holes may be arranged around the surface light source assembly 3. The first connection holes are provided on the surface light source sheath 32, which can maintain the integrity and moisture resistance of the plate structure of the light-transmitting member, such as a light-transmitting plate, a diffusion plate, etc. The first connection hole may be provided as a through hole.

[0091] In some embodiments of the present application, a second connection hole (not shown in the figure) may be provided on the shelf assembly 2. The second connection hole is provided on the shelf 22 sheath 21. The second connection hole is arranged opposite to the first connection hole. The connecting member 31 passes through the first connection hole and the second connection hole to realize the connection between the shelf assembly 2 and the surface light source assembly 3.

[0092] The connecting member 31 may adopt a screw. The first connection hole may be provided with an internal thread. The connecting member 31 is threadedly connected to the first connection hole. The second connection hole may be provided with an internal thread. The connecting member 31 is threadedly connected to the second connection hole. The threaded connection method has a simple structure and high connection stability, which is convenient for the disassembly and assembly between the surface light source assembly 3 and the shelf assembly 2.

[0093] In some embodiments of the present application, the second connection hole may be provided as a blind hole. The opening of the second connection hole faces the surface light source assembly 3 side, so that the connecting member 31 can sequentially pass through the first connection hole and the second connection hole and will not protrude from the upper surface of the shelf 22, ensuring the flatness of the surface of the shelf 22.

[0094] It can be understood that in other embodiments, ribbing may be provided on two opposite inner sidewalls of the box liner 11. The ribbing protrudes from the surface of the box liner 11 to form a supporting space for carrying the surface light source assembly 3. The opposite side edges of the surface light source assembly 3 can be placed on the ribbing at the same height on the two opposite inner sidewalls to achieve the connection of the surface light source assembly 3.

[0095] In some other embodiments, grooves may be formed on two opposite inner walls of the inner container 11. The edge of the surface light source assembly 3 may be inserted into the grooves to achieve the connection of the surface light source assembly 3.

[0096] For the above two types of connections between the surface light source assembly 3 and the inner container 11, the surface light source assembly 3 is not fixed, making it more convenient to take and place.

[0097] In summary, in the present application, the surface light source assembly 3 is installed below the shelf assembly 2 through the connecting member 31, so that the surface light source assembly 3 is not easily dropped and can be disassembled and assembled as a whole, facilitating the maintenance, disassembly and assembly of the surface light source assembly 3. No items need to be placed on the surface of the surface light source assembly 3, and the surface light source assembly 3 adopts a thin plate-like structure, which expands the heat dissipation area of the surface light source assembly 3, thereby improving the heat dissipation effect of the surface light source assembly 3. A gap is left between the shelf assembly 2 and the surface light source assembly 3, further increasing the heat dissipation area and improving the heat dissipation effect.

[0098] In addition, the shelf assembly 2 is light-transmissive, enabling the light emitted by the surface light source assembly 3 to illuminate the entire shelf space upward and downward, improving the lighting effect of the surface light source assembly 3.

[0099] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the application concept of the present application, and all such changes or substitutions should fall within the protection scope of the claims attached to the present application.
