[0045] It should be noted that, without conflict, different features in the embodiments of the present invention can be combined with each other.

[0046] With the rapid development of the refrigeration equipment industry, its internal lighting system has also undergone technological innovation: from the initial non-lighting design, to the application of traditional bulbs, to the popularization of LED light sources, and until now the mainstream large-area light source technology. This not only reflects the progress of lighting technology but also reflects the improvement of users' refined requirements for the refrigeration equipment experience. With its characteristics close to natural light and soft and uniform lighting effects, the large-area light source has now become a standard configuration for mid- to high-end refrigeration equipment.

[0047] However, the assembly process of the large-area light source is quite difficult. Through research by the inventor, it is found that compared with traditional light sources, the relatively large size of the large-area light source makes the conventional method of fixing the light source have limitations: the snap design is prone to light source detachment due to insufficient structural strength. In addition, the common assembly method of the top inner tank slot matching the snap in the existing technical solutions has high requirements for the mold accuracy, and the slot tolerance needs to be strictly controlled, otherwise quality problems such as looseness or abnormal noise are likely to occur; when using the screw fixing scheme, due to the large size of the surface light source, the screw fixing reduces the production efficiency and increases the labor cost because a large number of fastening points are required, which affects the installation efficiency of the refrigeration equipment in the assembly line operation.

[0048] In view of this, the present invention provides a refrigeration device, including the following structures.

[0049] A refrigeration device 10, please refer to Figure 1 and Figure 2 , including a box body 100, an inner container 200 having an opening in the horizontal direction, and an air duct assembly 300; the inner container 200 is located inside the box body 100, and the air duct assembly 300 is located on one side of the inner container 200 away from the opening.

[0050] In the refrigeration device 10, the box body 100 also has an opening, and the opening of the box body 100 faces the same side as the opening of the inner container 200. The opening is used to install the door body of the refrigeration device 10. In addition, the opening edge of the inner container 200 is usually designed with a flanging structure to increase rigidity and the bonding force with the box body 100. Correspondingly, the opening part of the box body 100 matches the flanging of the inner container 200, so as to form a stable support structure to prevent the refrigeration device 10 from deforming or cracking.

[0051] It should be noted that the inner container 200 of the refrigeration device 10 is usually pre-placed in the foaming mold inside the box body 100. After the foaming material is injected, it expands and cures on the side of the inner container 200 close to the box body 100, forming a foaming layer that tightly wraps the inner container 200. The foaming layer not only provides heat insulation, but also can enhance the overall rigidity of the refrigeration device 10, and the inner container 200 serves as a clean layer in direct contact with the storage space.

[0052] Please refer to Figure 1 and Figure 2 , the refrigeration device 10 further includes a surface light source assembly 400, and the surface light source assembly 400 includes a connecting portion 410, a decorative portion 420, and a surface light source board 430. Please refer to Figure 3 , the surface light source board 430 includes opposite first side edges 4301 and second side edges 4302. The first side edge 4301 of the surface light source board 430 is connected to the top of the air duct assembly 300 through the connecting portion 410. The surface light source board 430 is connected to the side of the top wall of the inner container 200 away from the box body 100, and the decorative portion 420 is connected to the second side edge 4302 of the surface light source board 430.

[0053] In the refrigeration device 10 of the present application, the air duct assembly 300 is located inside the inner container 200 and is close to the side of the inner container 200 away from the opening of the inner container 200. The top of the air duct assembly 300 is close to the top wall of the inner container 200. Therefore, in this embodiment, the first side 4301 of the surface light source board 430 is connected to the top of the air duct assembly 300 through the connecting portion 410, and then the surface light source board 430 is fixed to the top wall of the inner container 200 with fewer connecting pieces. At the same time, the second side 4302 of the surface light source board 430 is matched with the corresponding decoration portion 420, so that the surface light source board 430 can be accurately positioned and firmly fixed during the assembly process, and the operator can save time and effort during the assembly process; at the same time, this structure enables the surface light source board 430 to be perfectly embedded in the top wall of the inner container 200 of the refrigeration device 10, and the decoration portion 420 decorates and hides the second side 4302 of the surface light source board 430, making the overall surface light source board 430 look more beautiful and generous, meeting the aesthetic requirements of current users.

[0054] Wherein, the plane where the surface light source board 430 is located is parallel to the plane where the top wall of the inner container 200 is located.

[0055] In this embodiment, in order to ensure the lighting effect of the surface light source board 430 of the refrigeration device 10, it is necessary to embed the surface light source board 430 into the top wall of the inner container 200, make the light-emitting side face the inside of the inner container 200, and be parallel to the top wall of the inner container 200 at the same time. Therefore, the connecting portion 410 should have a structure capable of fixedly connecting the mutually perpendicular surface light source board 430 and the top of the air duct assembly 300.

[0056] In a possible implementation manner, please refer to Figure 4 , the connecting portion 410 includes a first support plate 411 and a second support plate 412 arranged parallel to the top wall of the inner container 200, and a third support plate 413 located on the same side of the first support plate 411 and the second support plate 412.

[0057] Wherein the third support plate 413 is perpendicular to the first support plate 411.

[0058] The first support plate 411, the second support plate 412 and the third support plate 413 form a groove for accommodating the first side 4301 of the surface light source board 430.

[0059] In this embodiment, the first support plate 411 of the connecting portion 410 can function to connect the first side 4301 of the surface light source plate 430. Meanwhile, the second support plate 412 designed parallel to it can play a role in secondarily supporting the first side 4301. The groove formed by the first support plate 411, the second support plate 412, and the third support plate 413 can accommodate the first side 4301 of the surface light source plate 430, improving the stability of the connection structure 435 between the surface light source plate 430 and the connecting portion 410.

[0060] Specifically, the width of the first support plate 411 in the direction close to the opening is 50 millimeters.

[0061] The width of the second support plate 412 in the direction close to the opening is 20 millimeters.

[0062] It should be noted that in other implementation manners of this embodiment, the widths of the first support plate 411 and the second support plate 412 in the direction close to the opening can be flexibly adjusted according to the sizes of the refrigeration device 10 and the surface light source plate 430, and no specific limitation is made here.

[0063] In a possible implementation manner, please refer to Figure 3 , the first side 4301 of the surface light source plate 430 includes a connection structure 435 extending towards the connecting portion 410. The connection structure 435 is respectively provided with a first bending portion 431 and a second bending portion 432 that are bent towards the top wall of the inner container 200 on the third side 4351 and the fourth side 4352 perpendicular to the first side 4301; the first bending portion 431 and the second bending portion 432 are respectively provided with a third bending portion 433 and a fourth bending portion 434 that are towards the center of the surface light source plate 430 and parallel to the surface light source plate 430.

[0064] The third side 4351, the first bending portion 431, and the third bending portion 433 form a groove, and the fourth side 4352, the second bending portion 432, and the fourth bending portion 434 form a groove for jointly inserting the first support plate 411.

[0065] In this way, a U-shaped structure that can be hung on the first support plate 411 is formed at the first side 4301 of the surface light source plate 430. The first support plate 411 is inserted into the U-shaped structure of the surface light source plate 430. Meanwhile, the first side 4301 of the surface light source plate 430 is inserted into the groove formed by the first support plate 411, the second support plate 412, and the third support plate 413. The structure is simple and has double guarantees, improving the stability of the connection structure 435 between the surface light source plate 430 and the connecting portion 410.

[0066] In a possible implementation manner, please refer to Figure 3, a recess may be provided on the surface of the first side 4301 of the surface light source plate 430 close to the second support plate 412 of the connecting portion 410, and the shape of the recess matches the shape of the second support plate 412 and the width in the direction close to the opening. In this way, not only can the structural stability of the connecting portion 410 and the surface light source plate 430 be improved, but also the aesthetics and safety of the refrigeration device 10 can be enhanced.

[0067] In a possible implementation manner, the length of the first bending portion 431 in the direction perpendicular to the top wall of the inner container 200 is greater than the thickness of the first support plate 411 in the direction close to the top wall of the inner container 200. In this way, it can be ensured that the first support plate 411 can be inserted into the U-shaped structure of the surface light source plate 430 and be stably supported by the U-shaped structure of the surface light source plate 430.

[0068] In a possible implementation manner, the length of the third support plate 413 in the direction perpendicular to the top wall of the inner container 200 is greater than the thickness of the surface light source plate 430 in the direction close to the top wall of the inner container 200. In this way, it can be ensured that the first side 4301 of the surface light source plate 430 can be inserted into the groove formed by the first support plate 411, the second support plate 412 and the third support plate 413 and be stably supported by the groove.

[0069] In a possible implementation manner, please refer to Figure 5 , the top of the air duct assembly 300 includes at least two first through holes 301; wherein, the central axis of the first through hole 301 is perpendicular to the top wall of the inner container 200.

[0070] Please refer to Figure 6 , the connecting portion 410 includes at least two second through holes 414, and the first through hole 301 and the second through hole 414 are coaxially arranged.

[0071] The refrigeration device 10 includes a first connecting member 510, and the first connecting member 510 fixes the connecting portion 410 to the top end of the air duct assembly 300 through the first through hole 301 and the second through hole 414.

[0072] Specifically, the connecting portion 410 can be designed in a strip shape to match the top of the air duct assembly 300; the top of the air duct assembly 300 can include 4 first through holes 301, and 4 corresponding second through holes 414 are designed at the corresponding assembly positions of the connecting portion 410, and the connecting portion 410 is fixed to the air duct assembly 300 through the first connecting member 510.

[0073] In this embodiment, the number and positions of the first through-hole 301 and the second through-hole 414 can be flexibly adjusted to adapt to refrigeration devices 10 of different sizes. For example, during the drilling process, the first through-hole 301 and the second through-hole 414 can be evenly distributed on the top of the air duct assembly 300 and the connecting portion 410 respectively to improve the connection stability. Or the first through-hole 301 and the second through-hole 414 can be distributed at the edges of the top of the air duct assembly 300 and the connecting portion 410 respectively, reducing the number of the first through-hole 301, the second through-hole 414 and the first connecting member 510 without affecting the structural stability. In addition, during the drilling process, it is also necessary to achieve a balance between the connection stability and the rigidity of the air duct assembly 300 and the connecting portion 410, and the structural strength of the top of the air duct assembly 300 and the connecting portion 410 should not be affected due to excessive drilling.

[0074] Optionally, the first connecting member 510 includes a screw, which can achieve a fastening connection between the connecting assembly and the top of the air duct assembly 300, and has a simple installation and relatively low cost.

[0075] In addition, in other embodiments of the present application, other types of first connecting members can also be selected, which are not specifically limited herein.

[0076] It should be noted that, in addition to the foregoing structure, please refer to Figure 4 and Figure 6 , the connecting portion 410 can also be designed with a groove for accommodating the shape of the top of the air duct assembly 300 to position the connecting portion 410 during the assembly of the refrigeration device 10 provided in the present application, and at the same time improve the connection stability between the top of the air duct assembly 300 and the connecting portion 410.

[0077] In a possible implementation manner, please refer to Figure 3 , the second side 4302 of the surface light source board 430 includes a third through-hole 436.

[0078] The refrigeration device 10 includes a second connecting member 520, and the second connecting member 520 fixes the surface light source board 430 on the top wall of the inner container 200 through the third through-hole 436.

[0079] In this embodiment, the number and positions of the third through-holes 436 at the second side 4302 can be flexibly adjusted to adapt to refrigeration devices 10 of different sizes. For example, during the drilling process, the third through-holes 436 can be evenly distributed at the second side 4302 of the surface light source plate 430 to improve the connection stability. Or the third through-holes 436 can be distributed at the edge of the second side 4302, reducing the number of the third through-holes 436 and the second connectors 520 without affecting the structural stability between the surface light source plate 430 and the top wall of the inner container 200. In addition, during the drilling process, it is also necessary to balance the connection stability and the rigidity between the surface light source plate 430 and the top wall of the inner container 200, and excessive drilling should not affect the structural strength of the surface light source plate 430 and the top wall of the inner container 200.

[0080] Optionally, the second connection assembly includes screws, which can achieve the fastening connection between the surface light source plate 430 and the top wall of the inner container 200, and the installation is simple and the cost is relatively low.

[0081] In a possible implementation manner, please refer to Figure 3 , at least one positioning post 437 is further included at the second side 4302 of the surface light source plate 430.

[0082] The top wall of the inner container 200 includes at least one positioning groove.

[0083] The positioning groove matches the shape of the positioning post 437.

[0084] During the assembly process of the refrigeration device 10 in this embodiment, in order to make the step of installing the surface light source plate 430 on the top wall of the inner container 200 more convenient, at least one positioning post 437 can be provided on the side of the second side 4302 of the surface light source plate 430 close to the inner wall of the inner container 200, and at the same time, a positioning groove corresponding to the positioning post 437 is provided on the top wall of the inner container 200. In this way, when assembling the surface light source plate 430, it can be easily positioned on the top wall of the inner container 200, thereby saving time and effort for the operator during the assembly process.

[0085] In a possible implementation manner, please refer to Figure 7 , at least one connecting groove 438 is included at the second side 4302 of the surface light source plate 430.

[0086] Please refer to Figure 8 , the decorative part 420 includes at least one connecting protrusion 421.

[0087] The connecting groove 438 matches the shape of the connecting protrusion 421.

[0088] Specifically, the decoration part 420 can be designed in a strip shape to match the second side 4302 of the surface light source panel 430; five groups of connecting grooves 438 are designed at the second side 4302 of the surface light source panel 430 to adapt to five groups of corresponding connecting protrusions 421, so that the decorative strip is snap-fitted onto the surface light source panel 430.

[0089] It should be noted that the decoration part 420 uses a material with a relatively low density, such as plastic, etc., with the aim of improving the stability of the surface light source panel 430 on the inner container 200.

[0090] Specifically, during the assembly process of the refrigeration device 10 of the present application, the operator first assembles the connecting part 410 and the air duct assembly 300 together using the first connecting piece 510 through the first through hole 301 and the second through hole 414, transports them to the assembly line, and then fixes the entire air duct assembly 300 in the box body 100. The first side 4301 of the surface light source panel 430 is inserted into the connecting part 410, and the second side 4302 is pressed into the top wall of the inner container 200. The entire surface light source panel 430 is installed on the inner container 200 and the box body 100 through the second connecting piece 520 via the third through hole 436. Finally, the connecting protrusions 421 of the decoration part 420 are snapped together with the connecting grooves 438 of the surface light source panel 430, so that the entire decoration part 420 is also embedded on the inner container 200 of the refrigeration device 10, while hiding the second connecting piece 520 and the third through hole 436.
