In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0047] Combine the following Figures 1 to 4 The utility model describes a refrigerator cabinet assembly and a refrigerator.

[0048] The first embodiment of the utility model provides a refrigerator box assembly, such as Figures 1 to 3 As shown, the cabinet assembly of the refrigerator includes a first plate body 100 and a second plate body 200, one of the first plate body 100 and the second plate body 200 is a back plate, and the other of the first plate body 100 and the second plate body 200 is a side plate; a protrusion 110 is provided at the edge of the first plate body 100, and a groove 210 cooperating with the protrusion 110 is provided at the edge of the second plate body 200, and the protrusion 110 and the groove 210 are interference fit.

[0049] The embodiment of the utility model completes the connection between the back plate and the side plate through the interference fit between the protrusion and the groove 210 to realize the assembly of the box assembly, which can reduce the assembly time of the box assembly and prevent the foam material inside the box from being exposed. The protrusion 110 and the groove 210 have an interference fit, so that the back plate and the side plate are tightly connected, have good anti-loosening performance, and can provide higher precision and rigidity.

[0050] The back and side panels of traditional box assemblies are connected by welding. The high temperature generated during the welding process can cause deformation of the plate. The quality of welding depends on the skill level of the operator, and it is difficult to guarantee the welding quality. Once the welding fails, the box assembly will be scrapped, resulting in waste.

[0051] In contrast, the interference fit between the protrusion 110 and the groove 210 does not generate high temperature during the assembly process, which can avoid deformation, residual stress and other problems caused by high temperature; the assembly is simple, and the operator can quickly get started without the need for training in professional skills such as welding; the protrusion 110 and the groove 210 can be separated relatively easily, which facilitates subsequent maintenance, disassembly or replacement, and is also conducive to the secondary use of the plate.

[0052] like Figures 2 to 3 As shown, one of the first plate body 100 and the second plate body 200 is a back plate, and the other of the first plate body 100 and the second plate body 200 is a side plate, that is, a protrusion 110 can be set at the edge of the back plate, and a groove 210 matching the protrusion 110 can be set at the edge of the side plate, or a protrusion 110 can be set at the edge of the side plate, and a groove 210 matching the protrusion 110 can be set at the edge of the back plate. Figure 1 The first plate body 100 is a back plate, and the second plate body 200 is a side plate. Of course, the first plate body 100 can also be a side plate, and the second plate body 200 is a back plate.

[0053] Generally, there are three side panels of the refrigerator assembly, corresponding to the three side edges connected to the back panel. The two sides of the back panel form the first side edge, and the top of the back panel forms the second side edge; the two side panels connected to the first side edge are the first side panels, and the side panels connected to the second side edge are the second side panels. When the refrigerator is in working state, the first side panels are located on both sides of the refrigerator, and the second side panels are located on the top of the refrigerator. Since the back panel is a rectangle with inconsistent length and width, the first side panel and the second side panel are inconsistent in size, therefore, a protrusion 110 can be provided on the first side panel and the second side panel, respectively, and a groove 210 can be provided on the second side panel and the first side panel, respectively; by providing a protrusion 110 on the first side panel and a groove 210 on the second side panel, different side panels can be distinguished, and assembly efficiency can be improved. Of course, in other embodiments, the groove 210 can also be provided on the first side panel and the second side panel, respectively, and the protrusion 110 can be provided on the second side panel and the first side panel, respectively, and the embodiment of the utility model does not impose any special restrictions on this.

[0054] In one embodiment, Figure 3 As shown, a protrusion 110 is provided on the first side of the first plate body 100, and a stopper 120 is provided on the second side of the first plate body 100, the first side and the second side are opposite; the stopper 120 abuts against the open end of the groove 210. The stopper 120 serves as a limiter for the groove 210. During installation, the protrusion 110 is inserted into the groove 210. When the open end of the groove 210 abuts against the stopper 120, the protrusion 110 cannot continue to be inserted into the groove 210. The protrusion 110 and the stopper 120 are respectively provided on opposite sides, so that the size of the stopper 120 protruding from the first plate body 100 can be reduced, thereby saving materials.

[0055] In one embodiment, at least one of the stopper 120 and the protrusion 110 is formed by bending.

[0056] It is understandable that the stopper 120 or the protrusion 110 is formed by bending the first plate 100, or the stopper 120 and the protrusion 110 are formed by bending the first plate 100. Since the back plate and the side plate of the refrigerator are generally made of metal material, the surface of the metal material is not easy to be processed into a convex block compared with the plastic material. Therefore, the protrusion 110 and the stopper 120 are formed by bending to improve the processing efficiency of the first plate 100.

[0057] In one embodiment, the edge of the second plate body 200 is bent to form a groove 210, and at least one of the side walls of the groove 210 includes two laminated plates 220. It can be understood that at least one of the side walls of the groove 210 includes two laminated plates 220, and it can be that one of the side walls of the groove 210 includes two laminated plates 220, or both side plates include two laminated plates 220. The embodiment of the utility model does not particularly limit the specific structure of the side wall of the groove 210.

[0058] It is understandable that since the back plate and side plates of the refrigerator are generally made of metal materials, it is not easy to process the groove 210 on the surface of the metal plate body. The groove 210 is formed on the second plate body 200 using a bending process, and the groove 210 can be quickly formed on the second plate body 200. At least one of the side walls of the groove 210 includes two stacked plates 220, and the two stacked plates 220 are stacked to form the side walls of the groove 210. The two stacked plates 220 can support each other, thereby improving the strength and bearing capacity of the groove 210 and reducing deformation.

[0059] In addition, by utilizing the protrusion 110 and the groove 210 formed by bending, the first plate body 100 and the second plate body 200 can be directly connected through the interference fit of the protrusion 110 and the groove 210 without any auxiliary tools, without providing an additional connecting structure on the first plate body 100 and the second plate body 200, thereby simplifying the structure of the first plate body 100 and the second plate body 200.

[0060] In one embodiment, the edge of the first plate 100 can be bent to form at least two protrusions 110, and multiple protrusions 110 are arranged on the edge of the first plate 100. The provision of multiple protrusions 110 can increase the friction between the protrusions 110 and the inner wall of the groove 210; at the same time, when the overall size of the protrusions 110 of the first plate 100 remains unchanged, the more protrusions 110 there are, the greater the degree of bending of a single protrusion 110, and therefore, the greater the strength of the protrusion 110. Of course, in other embodiments, one, two, three or four protrusions 110 can be provided, and the embodiment of the utility model does not particularly limit the number of protrusions 110.

[0061] In one embodiment, Figure 3As shown, the two stacked plates 220 are transitionally connected by an arc plate 230, and the distance between the two stacked plates 220 gradually increases from the bottom plate 500 of the groove 210 toward the opening of the groove 210 to form a closed concave space in the groove 210.

[0062] It can be understood that the arc plate 230 serves to connect the two stacked plates 220, and the arc shape can avoid scratching the staff; on the other hand, the arc plate 230 can isolate the two stacked plates 220 to prevent the two stacked plates 220 from being close to each other, so that the distance between the two stacked plates 220 gradually increases from the bottom plate 500 of the groove 210 toward the opening of the groove 210, so that the two stacked plates 220 apply a pressure to the edge of the first plate body 100 at the opening position of the groove 210 to prevent the protrusion 110 from sliding out of the groove 210; the closing of the recessed space can further limit the protrusion 110 from sliding out.

[0063] In one embodiment, Figure 3 As shown, the first side wall of the groove 210 includes two stacking plates 220, and the groove 210 also includes a second side wall opposite to the first side wall, and the second side wall is formed with a guide surface at the notch position of the groove 210, and the guide surface is inclined toward the outside of the groove 210. The two stacking plates 220 improve the bearing capacity of the groove 210, and the guide surface is formed at the notch position of the groove 210, and the guide surface is used to guide the protrusion 110 to be inserted into the groove 210, thereby improving the assembly efficiency.

[0064] Specifically, the second side wall of the groove 210 is a single plate, and the second side wall is bent at the notch position corresponding to the groove 210 to form a guide surface. The single plate is easy to bend and process, reducing the difficulty of processing; during assembly, the single plate is easy to bend, which is convenient for assembly.

[0065] In one embodiment, the stack 220 includes a first stack 221 parallel to the second side wall, and a second stack 222 at an angle to the first side wall. The second stack 222 is located on the side of the first stack 221 facing the recessed space, so that a closed end is formed at the opening of the recessed space to lock the protrusion 110.

[0066] It can be understood that the first stack of plates 221 is parallel to the second side wall, and the first stack of plates 221 is located on the side away from the recessed space, that is, the first stack of plates 221 is located on the outside of the groove 210, so as to avoid the first stack of plates 221 protruding from the surface of the first plate body 100 after the first plate body 100 and the second plate body 200 are assembled, thereby affecting the flatness of the appearance of the refrigerator assembly.

[0067] In one embodiment, after the edge of the second plate 200 is bent to form the groove 210 , the middle of the second plate 200 is in close contact with the bottom plate of the groove 210 to support the groove 210 and improve the bearing capacity of the groove 210 .

[0068] In one embodiment, the first plate body 100 is provided with a stopper 120, and the arc plate 230 abuts against the stopper 120. Since the arc plate 230 is a transition plate between the first stack of plates 221 and the second stack of plates 222, the arc plate 230 is provided corresponding to the stopper 120, so that after the assembly is completed, the arc plate 230 abuts against the stopper 120 to limit the protrusion from further inserting into the groove 210, and at this time, the first stack of plates 221 and the second stack of plates 222 play the role of supporting the arc plate 230.

[0069] Specifically, both sides of the stopper 120 have arc surfaces to transitionally connect the stopper to the first plate 100 , and the arc surfaces and the side walls of the stopper 120 form abutment depressions against the arc plate 230 to fit tightly against the arc plate 230 .

[0070] In one embodiment, the protrusion 110 may pass through the side of the first plate 100 or the groove 210 may pass through the side of the second plate 200, or the protrusion 110 may pass through the side of the first plate 100 and the groove 210 may pass through the side of the second plate 200. The protrusion 110 passes through the side of the first plate 100 and the groove 210 passes through the side of the second plate 200, which can prevent the foam material inside the box assembly from leaking out. Since the protrusion 110 passing through the side of the first plate 100 and the groove 210 passing through the side of the second plate 200 are interference fit, the sealing effect of the box assembly can be improved, eliminating the sponge tape sealing process.

[0071] In one embodiment, a compartment 300 of the refrigerator is formed between the back plate and the side plates; the protrusion 110 and the groove 210 are located inside the compartment 300 to maintain the flatness of the appearance of the box assembly.

[0072] like Figure 4 As shown, the embodiment of the utility model further includes a panel 400 and a bottom plate 500; the panel 400 forms a compressor compartment for placing the compressor, and the panel 400 is provided with a pipe outlet hole 410, and the pipe outlet hole 410 can be passed through by a condenser outlet pipe or a drain pipe of a refrigerator. Among them, the condenser outlet pipe includes a condenser water inlet pipe and a condenser water outlet pipe. At least two pipe outlet holes 410 are provided on the panel 400, and the condenser water inlet pipe and the condenser water outlet pipe are connected to the compressor after penetrating two pipe outlet holes 410 one by one.

[0073] Specifically, the enclosure 400 has a side close to the press chamber and a side away from the press chamber, and the bottom plate 500 is located on the side of the enclosure 400 away from the press chamber. The enclosure 400 can be an arc-shaped plate, and one end of the arc-shaped enclosure 400 is connected to the bottom plate 500 in the arc direction. Alternatively, the enclosure 400 is a folding plate, and the folding enclosure 400 includes a top plate 420 and a connecting plate 430 that are connected to each other, and the top plate 420 and the connecting plate 430 are connected and arranged at an angle. For example, the top plate 420 and the connecting plate 430 are connected to form an "L"-shaped plate structure. Optionally, a chamfer is formed between the top plate 420 and the connecting plate 430. Among them, the enclosure 400 or the bottom plate 500 can be formed by pressurization, bending, injection molding or vacuum molding processes.

[0074] As a specific example, the connecting plate 430 is a vertical plate, the top plate 420 is connected to the upper end of the vertical plate, the bottom plate 500 is connected to the lower end of the vertical plate, and the top plate 420 and the bottom plate 500 are respectively located on both sides of the connecting plate 430. When the refrigerator is in use, the bottom plate 500 is horizontally arranged, and the connecting plate 430 is vertically arranged or tilted at a certain angle relative to the vertical plane in a direction away from the bottom plate 500. The top plate 420 is flat or tilted at a certain angle relative to the horizontal plane in a direction away from the bottom plate 500. Optionally, the pipe outlet hole 410 is arranged on the top plate 420.

[0075] In one embodiment, Figure 4 As shown, the enclosure 400 includes a top plate 420, a connecting plate 430 and two end plates 440, the top plate 420 and the bottom plate 500 are respectively connected to the two ends of the end plate 440 and are respectively located on both sides of the connecting plate 430. The two end plates 440 are respectively connected to the other two ends of the connecting plate 430 and are located on the same side of the end plate 440 as the top plate 420, and the end plates 440 are connected to the top plate 420. The top plate 420, the connecting plate 430 and the two end plates 440 are integrally formed.

[0076] Specifically, the connecting plate 430 has a first end and a second end facing each other and a third end and a fourth end facing each other. The bottom plate 500 is connected to the first end of the connecting plate 430, and the top plate 420 is connected to the second end of the connecting plate 430. One of the end plates 440 is connected to the third end of the connecting plate 430, and the other end plate 440 is connected to the fourth end of the connecting plate 430. Optionally, the connecting plate 430 and the top plate 420 are connected in an arc transition.

[0077] The enclosure 400 is provided with a wire hole 450 through which wires can pass; the wire hole 450 can be provided on the top plate 420 or the connecting plate 430 , or on the chamfer between the top plate 420 and the connecting plate 430 .

[0078] The back plate is connected to the bottom plate 500 through the enclosure 400. Specifically, the back plate is connected to one end of the top plate 420 away from the connecting plate 430, and the bottom plate 500 is connected to one end of the connecting plate 430 away from the top plate 420. The back plate and the bottom plate 500 are perpendicular to each other. When the refrigerator is in use, the bottom plate 500 is horizontally arranged, and the back plate is vertically arranged, and the back plate is located above the bottom plate 500 and the enclosure 400. Among them, the bottom plate 500, the enclosure 400 and the back plate are all PVC sheets. The bottom plate 500, the enclosure 400 and the back plate can be integrally formed by processes such as vacuum forming, injection molding, and stamping.

[0079] In one embodiment, the enclosure 400 and the bottom plate 500 are provided with ventilation holes. The ventilation holes can be provided on the connecting plate 430 and the bottom plate 500. The ventilation holes are provided on the connecting plate 430, the bottom plate 500, the top plate 420 and / or the end plate 440. Since the side of the enclosure 400 and the bottom plate 500 facing away from the foaming cavity is a non-appearance surface, even if the bubble leaks, it does not affect the appearance. Alternatively, a breathable tape is pasted on the side of the enclosure 400 and the bottom plate 500 facing away from the foaming cavity. Among them, the ventilation holes can be formed by mechanical punching after the enclosure 400 and the bottom plate 500 are vacuum-formed.

[0080] Furthermore, the back plate is provided with a foaming agent injection hole 130, and the injection hole 130 is located at one end of the back plate away from the enclosure 400. That is, the injection hole 130 is located at the upper end of the back plate.
