[0056] Reference is made below to Figures 1-22A storage device according to embodiments of the present application is described.

[0057] It should be noted that the storage device in the present embodiment can be understood as a general refrigeration storage device, including but not limited to a refrigerator, a freezer, a display cabinet, a beverage cabinet, a wine cabinet, a cold fresh cabinet, and a refrigeration vending machine, etc. The storage device has various structural forms and a wide range of applications.

[0060] As shown in Figure 1 , Figure 2 and Figure 12 , the storage device according to embodiments of the present application includes a cabinet 1, a cabinet opening 3, a door body 4, and a refrigeration unit 2.

[0061] The cabinet 1 defines a storage compartment 14 with an open end. The cabinet opening 3 is installed at the open end of the cabinet 1 and is provided with an air duct cavity 34 having an air inlet 341 and an air outlet 342. The door body 4 is pivotally installed on the cabinet opening 3 and is used to close the storage compartment 14. The refrigeration unit 2 is arranged in the storage compartment 14 and divides the storage compartment 14 into at least two cavities. The air inlet 341 is in communication with the refrigeration unit 2, and the air outlet 342 is in communication with the at least two cavities.

[0062] The door body 4 can be connected to the side wall of the cabinet 1 by a pivot structure. The door body 4 can be opened or closed relative to the cabinet 1 to close or open the storage compartment 14.

[0063] The storage compartment 14 can be divided into two or more cavities by the refrigeration unit 2. The multiple cavities can be in communication with each other for the classified storage of articles, facilitating the quick access of users. Alternatively, the multiple cavities can be isolated, so that different cavities have different temperature controls to meet the storage needs of articles with different temperature requirements.

[0064] The refrigeration unit 2 can include multiple refrigeration sub-units, which can divide the storage compartment 14 into three or more cavities. The multiple refrigeration sub-units can share a set of refrigeration components 23. Alternatively, the refrigeration unit 2 is a whole, which can divide the storage compartment 14 into a first compartment 141 and a second compartment 142.

[0065] The refrigeration unit 2 is used to generate cold air to maintain the low temperature of the storage compartment 14, and the refrigeration unit 2 includes a refrigeration component 23 such as an evaporator 231 and a fan, and has an air supply port 211 and an air return port 212, both of which are in communication with at least two cavities to achieve the circulation of cold air in the storage compartment 14.

[0066] The refrigeration unit 2 can be placed in the storage compartment 14 from the open end of the cabinet 1 and connected with the cabinet 1, and the refrigeration unit 2 can be connected with the cabinet 1 through at least one of plug-in connection, clamping and the like.

[0067] The cabinet opening 3 is used to connect the cabinet 1 and the door body 4, and is arranged around the circumference of the cabinet 1 at the open end of the cabinet 1. The air duct cavity 34 is located in the cabinet opening 3, which can realize the integration of the air duct structure and the cabinet opening 3, and cancels the conventional air duct cover plate and the air duct cavity 34 embedded parts, so that the structure design is simple, the process is simple, and the overall cost is reduced.

[0068] The cabinet opening 3 can be integrally injection molded or formed by sheet metal stamping and bending. The cabinet opening 3 can be connected with the cabinet 1 through one or more of plug-in connection, buckle connection and screw connection.

[0069] The cabinet opening 3 is connected with the open end of the cabinet 1 and extends around the circumference of the cabinet 1. The air duct cavity 34 extends along the extension direction of the cabinet opening 3. The air outlet 342 can be provided with one or more. In the case of providing multiple air outlets 342, the multiple air outlets 342 are arranged at intervals along the extension direction of the air duct cavity 34, i.e. the storage compartment 14 is arranged with multiple air outlets 342 around the circumference, which can realize multiple air outlets 342 to blow cold air, four-side air outlet, high refrigeration efficiency, and improve the uniformity of the temperature in the storage equipment.

[0070] In the related art, the air-cooled refrigerator has high cost in the air duct structure, and the air duct structure is mainly composed of an air duct cover plate and an air duct embedded cavity, which increases the number of parts of the storage equipment and prolongs the production cycle.

[0071] According to the storage equipment provided in the embodiments of the present application, the cabinet opening 3 is provided with the air duct cavity 34, which can communicate the refrigeration unit 2 and the multiple cavities, realize the integration of the air duct structure and the cabinet opening 3, cancel the conventional air duct cover plate and the air duct cavity 34 embedded parts, and the structure design is simple, the process is simple, and the overall cost is reduced, the production cycle is reduced, and the production efficiency is improved.

[0072] In some embodiments, as shown in Figure 1 The cabinet 1 includes an outer shell 11, an inner container 12 and a heat preservation layer 15 between the outer shell 11 and the inner container 12. Part of the wall surface of the inner container 12 is used to form part of the wall surface of the air duct cavity 34.

[0073] The cabinet opening 3 has an open end, and the open end of the cabinet opening 3 is connected with an end of the inner container 12, and part of the wall surface of the end of the inner container 12 is used to form part of the wall surface of the air duct cavity 34. In comparison with producing a closed air duct cavity 34 on the cabinet opening 3, producing a part of the wall surface of the air duct cavity 34 that is open can increase the cross-sectional area of the air duct cavity 34, increase the flow capacity, and facilitate the processing and production of the cabinet opening 3.

[0074] The air duct cavity 34 is jointly defined by the inner container 12 and the cabinet opening 3. In comparison with the cabinet opening 3 having a closed air duct cavity 34, the cabinet opening 3 having an open end simplifies the production difficulty and reduces the cost.

[0075] In some embodiments, as shown in Figure 16 and Figure 20 The open end of the inner container 12 includes at least two bending sections that are sequentially connected and relatively bent. The cabinet opening 3 includes a first wall 31, a top wall, and a second wall 33 that are sequentially connected. The first wall 31 is located inside the second wall 33 and is spaced apart from the second wall 33. The first wall 31 and the second wall 33 are both connected with different sections of the at least two bending sections to form the air duct cavity 34 between the cabinet opening 3 and the inner container 12.

[0076] The end surface of the open end of the inner container 12 forms the at least two bending sections. The at least two bending sections can be continuously bent towards the inside of the storage compartment 14 or continuously bent towards the side away from the storage compartment 14. The first wall 31, the top wall, and the second wall 33 jointly define the air duct cavity 34 with part of the at least two bending sections, that is, the inner container 12 and the cabinet opening 3 jointly define the air duct cavity 34.

[0077] In the present embodiment, the at least two bending sections that are sequentially connected and relatively bent can be integrally formed. By arranging the first wall 31 and the second wall 33 to be connected with different sections of the at least two bending sections, multi-point connection is achieved, the stability of the connection between the two can be increased, and the air duct cavity 34 can be formed.

[0078] The inner container 12 can be made of at least the following two materials:

[0079] First, the inner container 12 can be a plastic part. The material of the plastic part can be a PS or ABS plate. The inner container 12 can be integrally formed by adsorption of the plastic part.

[0080] In the present embodiment, as shown in Figure 20As shown, the at least two bending sections include a first section 1221, a second section 1222, a third section 1223 and a fourth section 1224 connected in sequence, the first section 1221 is bent outwardly relative to the side wall of the inner container 12, the second section 1222 is bent upwardly relative to the first section 1221, the third section 1223 is bent outwardly relative to the second section 1222, and the fourth section 1224 is bent upwardly relative to the third section 1223; the second section 1222 is connected to the outer side of the first wall 31, the third section 1223 forms part of the wall surface of the air duct cavity 34, and the fourth section 1224 is connected to the second wall 33.

[0081] In the embodiment, the first section 1221 and the second section 1222 form a recess relative to the side wall of the inner container 12, the top wall and the side wall facing the storage compartment 14 of the recess are open, at least part of the first wall 31 is located in the recess, and the side of the first wall 31 facing the storage compartment 14 is flush with the inner side of the inner container 12, recessed relative to the inner side of the inner container 12, or slightly convex relative to the inner side of the inner container 12, which can reduce the occupation of the first wall 31 to the volume of the storage compartment 14. The first wall 31 is connected to the second section 1222, and the connection mode can be clamping or plug-in connection.

[0082] The bottom wall of the first wall 31 can be abutted or connected to the first section 1221, and the first section 1221 supports the first wall 31 to increase the stability of the connection between the cabinet opening 3 and the cabinet 1.

[0083] The fourth section 1224 is connected to the inner wall or the outer wall of the second wall 33, and the connection mode can be clamping or plug-in connection to increase the stability of the connection between the cabinet opening 3 and the cabinet 1.

[0084] In the case where the fourth section 1224 is connected to the inner wall of the second wall 33, the third section 1223 integrally forms the bottom wall of the air duct cavity 34, which can reduce the occupation of the second wall 33 to the air duct cavity 34 and improve the ventilation efficiency of the air duct cavity 34.

[0085] In the case where the fourth section 1224 is connected to the outer wall of the second wall 33, part of the third section 1223 forms the bottom wall of the air duct cavity 34, which increases the stability of the connection between the cabinet opening 3 and the cabinet 1.

[0086] In some embodiments, as shown in Figure 20 and Figure 21 The second section 1222 is provided with a first connecting structure 1231, the first wall 31 is provided with a second connecting structure 1232, and the first connecting structure 1231 and the second connecting structure 1232 are clamped; or, the fourth section 1224 is provided with a third connecting structure 1233, the second wall 33 is provided with a fourth connecting structure 1235, and the third connecting structure 1233 and the fourth connecting structure 1235 are clamped.

[0088] In the present embodiment, by clamping the first wall 31 and the second wall 33 with the inner container 12 respectively, the stability of the connection between the cabinet opening 3 and the inner container 12 can be increased, and fast connection can be realized at the same time.

[0089] Among them, the connecting structure between the first connecting structure 1231 and the second connecting structure 1232 can be the same as or different from the connecting structure of the third connecting structure 1233 and the fourth connecting structure 1235.

[0090] In some embodiments, one of the first connecting structure 1231 and the first connecting structure 1231 is a groove structure or a hole structure, and the other of the first connecting structure 1231 and the first connecting structure 1231 is a sliding block. The open end of the groove structure faces the storage compartment 14, and the sliding block has a clamping surface and a guide surface connected thereto, and the guide surface is arranged at an acute angle with the clamping surface.

[0091] For example, as shown in Figure 21 , the first connecting structure 1231 is a groove structure or a hole structure, the second connecting structure 1232 is a sliding block, the sliding block has a clamping surface and a guide surface connected thereto, and the guide surface is arranged at an acute angle with the first wall 31 to make the second connecting structure 1232 smoothly slide into the groove structure or the hole structure, and the clamping surface is arranged at a right angle or an obtuse angle with the first wall 31, and the clamping surface is clamped with the groove structure or the hole structure to reduce the risk of the second connecting structure 1232 falling out of the first connecting structure 1231.

[0092] For example, the second connecting structure 1232 is a groove structure or a hole structure, and the first connecting structure 1231 is a sliding block, the sliding block has a clamping surface and a guide surface connected thereto, and the guide surface is arranged at an obtuse angle with the second section 1222 to make the first connecting structure 1231 smoothly slide into the groove structure or the hole structure, and the clamping surface is arranged at a right angle or an acute angle with the second section 1222, and the clamping surface is clamped with the groove structure or the hole structure to reduce the risk of the first connecting structure 1231 falling out of the second connecting structure 1232.

[0093] Secondly, the inner container 12 can be a sheet metal part, and the sheet metal part can be made of an aluminum plate, a PCM plate or a stainless steel plate. The inner container 12 can be formed by stamping the sheet metal part.

[0094] In the present embodiment, as shown in Figure 16 and Figure 17As shown, the at least two bending sections include a fifth section 1225 and a sixth section 1226, the fifth section 1225 is bent outwardly relative to the side wall of the inner container 12, and the sixth section 1226 is bent upwardly relative to the fifth section 1225; the fifth section 1225 forms part of the wall of the air duct cavity 34, and the fifth section 1225 is connected with the first wall 31, and the sixth section 1226 is connected with the second wall 33.

[0095] The fifth section 1225 and the first wall 31 can be connected by at least one of plug-in connection and clamping connection, and the sixth section 1226 and the second wall 33 can be connected by at least one of plug-in connection and clamping connection, and part of the fifth section 1225 forms part of the wall of the air duct cavity 34.

[0096] It should be noted that the fewer bending sections provided on the sheet metal part can reduce the damage to the structural strength, and at the same time can reduce the number of sheet metal stamping, thereby reducing the production cost and production difficulty.

[0097] In some embodiments, as shown in Figure 14 and Figure 15 The inner container 12 further includes an angle sealing piece 129, the inner container 12 has a gap 1227 at the corner of the two adjacent walls of the open end, and the angle sealing piece 129 is arranged at the gap 1227, the angle sealing piece 129 is connected with the cabinet opening 3 and the inner container 12 respectively, and part of the wall of the angle sealing piece 129 is used to form part of the wall of the air duct cavity 34.

[0098] It can be understood that the end of the inner container 12 forms a gap 1227 at the corner of the two adjacent walls during the stamping and bending process, and the angle sealing piece 129 is used to connect the two adjacent walls to fill the gap 1227, and the angle sealing piece 129, the inner container 12 and the cabinet opening 3 jointly define the air duct cavity 34.

[0099] The angle sealing piece 129 can be connected with the outer side wall of the inner container 12, or can be connected with the inner side wall of the inner container 12, and can be installed according to the actual structure.

[0100] The projection of the angle sealing piece 129 and the projection of the open end of the inner container 12 have a coinciding part in the first direction as the projection direction, and the angle sealing piece 129 is connected with the cabinet opening 3 and the inner container 12 respectively to increase the stability of the connection of the three.

[0101] In some embodiments, as shown in Figure 15 The angle sealing piece 129 includes a first face 1291, a second face 1292 and a third face 1293, the first face 1291 is connected with the outer side wall of the inner container 12, the second face 1292 is connected with the fifth section 1225, and the third face 1293 is connected with the sixth section 1226.

[0102] As shown in Figure 15 and Figure 16As shown in

[0103] The fifth connecting structure 1236 is a sliding block, which has a connecting surface and a guiding surface. The guiding surface is arranged at an obtuse angle with the second wall 33 to facilitate the sliding of the fifth connecting structure 1236 into the second through hole 1295. The connecting surface is arranged at a right angle or an acute angle with the second wall 33, and is clamped with the second through hole 1295 to reduce the risk of the fifth connecting structure 1236 falling out of the second through hole 1295.

[0104] In some embodiments, as shown in Figure 16 and Figure 18 The first wall 31 is arranged in the storage compartment 14 and is provided with a plurality of air outlets 342, which are all in communication with the at least two cavities. The second wall 33 is arranged outside the storage compartment 14 and is provided with a reinforcing rib 331.

[0105] As shown in Figure 20 The second wall 33 is provided with a reinforcing rib 331, which can increase the structural strength of the cabinet opening 3. The plurality of air outlets 342 are arranged along the extension direction of the first wall 31 to achieve air supply on four sides of the storage compartment 14, improve the refrigeration effect and efficiency, and improve the uniformity of the temperature.

[0106] The reinforcing rib 331 can be provided with a plurality of reinforcing ribs, which can be arranged at intervals along the extension direction of the second wall 33 to further increase the structural strength of the cabinet opening 3.

[0107] In some embodiments, the box body 1 is provided with a first mounting structure 13, and the refrigeration unit 2 is provided with a second mounting structure 24 for connecting with the first mounting structure 13.

[0108] The first mounting structure 13 is arranged on the side wall of the cabinet 1, and the second mounting structure 24 is correspondingly arranged on the side wall of the refrigeration unit 2, and the second mounting structure 24 and the first mounting structure 13 can be clamped; or the first mounting structure 13 is arranged on the bottom wall of the cabinet 1, and the second mounting structure 24 is correspondingly arranged on the bottom wall of the refrigeration unit 2, and the second mounting structure 24 and the first mounting structure 13 can be connected through plug-in connection; or the first mounting structure 13 is arranged on the side wall and the bottom wall of the cabinet 1, and the second mounting structure 24 is correspondingly arranged on the side wall and the bottom wall of the refrigeration unit 2, and the second mounting structure 24 and the first mounting structure 13 can be connected through the connection mode of plug-in connection and clamping.

[0109] It should be noted that the production line of the storage device includes two parallel sub-production lines that can produce simultaneously, one of which produces the refrigeration unit 2 and the other produces the cabinet 1. After the refrigeration unit 2 is produced and assembled, the refrigeration unit 2 production line intersects with the cabinet 1 production line, and the refrigeration unit 2 and the cabinet 1 are assembled. That is, the assembly of each refrigeration component in the refrigeration unit 2 is separated from the production line of the storage device, and the multiple beats of assembling multiple refrigeration components with the cabinet 1 become the assembly of two assemblies of the refrigeration unit 2 and the cabinet 1. Therefore, compared with a production line in which multiple components are sequentially assembled into a storage device, the two sub-production lines of the refrigeration unit 2 and the cabinet 1 are parallel and simultaneously produced, and the assembly of the two assemblies is improved, saving production beats and personnel.

[0110] In related technologies, the production line of the storage device is a production line in which all components in the storage device are sequentially assembled. Each component has its own station, and multiple components need to be sequentially assembled by machines or personnel according to the installation beat to complete the production of one storage device. When the production line of the storage device is at a certain installation beat, the machines or personnel of other large number of installation stations are idle, causing waste of machines, personnel and beats.

[0111] According to the storage device provided in the embodiments of the present application, the refrigeration unit 2 can be assembled with the first mounting structure 13 of the cabinet 1 through the second mounting structure 24. The assembly of each refrigeration component in the refrigeration unit 2 is separated from the production line of the storage device, and the multiple beats of assembling multiple refrigeration components with the cabinet 1 become the assembly of two assemblies of the refrigeration unit 2 and the cabinet 1, improving the production efficiency and saving the production beats and personnel.

[0112] In some embodiments, as shown in Figure 2 The cabinet 1 includes an outer shell 11, an inner container 12, and a heat preservation layer 15 between the outer shell 11 and the inner container 12. The cabinet 1 is configured to form the heat preservation layer 15 between the outer shell 11 and the inner container 12 after the refrigeration unit 2 is installed in the inner container 12.

[0113] In the production line of the box body 1, after the outer shell 11 and the inner container 12 are assembled, the production line of the refrigeration unit 2 intersects with the production line of the box body 1, the refrigeration unit 2 is assembled with the box body 1, and after the refrigeration unit 2 is assembled with the inner container 12, the beat of forming the heat preservation layer 15 between the outer shell 11 and the inner container 12 is performed.

[0114] In the embodiment, since the return air pipe group 233 in the refrigeration unit 2 needs to communicate with the compressor outside the inner container 12, the refrigeration unit 2 is assembled with the inner container 12 before the outer shell 11 and the inner container 12 are filled with the heat preservation material, so that part of the return air pipe group 233 is located in the heat preservation layer 15, the heat preservation layer 15 can protect and fix part of the return air pipe group 233 located therein, reduce the occupation of the storage compartment 14, and simplify the assembly process of the box body 1 and the refrigeration unit 2.

[0115] In some embodiments, as shown in Figure 2 , Figure 11 and Figure 14 , the box body 1 comprises an outer shell 11, an inner container 12, and a heat preservation layer 15 located between the outer shell 11 and the inner container 12, the inner container 12 is provided with a through hole 121; the refrigeration unit 2 comprises a return air pipe group 233, one end of the return air pipe group 233 is used to pass through the through hole 121 and the heat preservation layer 15 and communicate with the compressor.

[0116] Among them, the return air pipe group 233 is used to communicate the evaporator 231 and the compressor, one end of the return air pipe group 233 extends out of the through hole 121 and communicates with the compressor through the gap between the outer shell 11 and the inner container 12, after the assembly of the refrigeration unit 2 and the box body 1 is completed, the gap between the outer shell 11 and the inner container 12 is filled with the heat preservation material to form the heat preservation layer 15, part of the return air pipe group 233 between the outer shell 11 and the inner container 12 is embedded in the heat preservation layer 15, and the heat preservation layer 15 can protect and fix part of the return air pipe group 233 located therein.

[0117] In some embodiments, as shown in Figure 4 and Figure 13 , the first mounting structure 13 and the second mounting structure 24 extend along the first direction, and the first direction is the normal direction of the opening surface of the storage compartment 14.

[0118] The first mounting structure 13 and the second mounting structure 24 extend along the direction perpendicular to the opening surface of the storage compartment 14.

[0119] In the embodiment, the refrigeration unit 2 is inserted into the storage compartment 14 from the opening surface of the storage compartment 14, that is, the refrigeration unit 2 moves along the first direction, and the extension of the first mounting structure 13 and the second mounting structure 24 along the first direction can reduce the interference with the movement of the refrigeration unit 2, facilitate assembly, prolong the connection length of the first mounting structure 13 and the second mounting structure 24, and increase the stability of the connection between the refrigeration unit 2 and the box body 1.

[0120] The first mounting structure 13 and the second mounting structure 24 at least include the following three structures:

[0121] Firstly, the first mounting structure 13 is arranged on the side wall of the cabinet 1, the second mounting structure 24 is arranged on the side wall of the refrigeration unit 2, one of the first mounting structure 13 and the second mounting structure 24 includes a sliding groove 241, the other of the first mounting structure 13 and the second mounting structure 24 includes a sliding rail matched with the sliding groove 241, and the sliding groove 241 extends to the end of the device.

[0123] The sliding groove 241 extends to the end of the device, that is, one end of the sliding groove 241 is open, so as to facilitate the insertion of the sliding rail from the open end of the sliding groove 241, and improve the convenience of assembling the refrigeration unit 2 and the storage compartment 14.

[0124] The first mounting structure 13 and the second mounting structure 24 are connected in a concave-convex matching mode of the sliding groove 241 and the sliding rail, and the first mounting structure 13 and the second mounting structure 24 have a guiding effect on each other, so that the refrigeration unit 2 can be inserted into the storage compartment 14 along the first direction.

[0126] Thirdly, the above two connection modes are combined.

[0127] In some embodiments, the refrigeration unit 2 includes a box body 21, a support assembly and a refrigeration assembly 23 arranged in the box body 21; the second mounting structure 24 includes a sliding groove 241 arranged on the support assembly and a avoiding opening 242 arranged on the box body 21, the avoiding opening 242 is used for avoiding the sliding groove 241, the sliding groove 241 extends to the end of the support assembly, and the avoiding opening 242 extends to the end of the box body 21; the first mounting structure 13 includes a sliding rail.

[0128] The refrigeration unit 2 integrates multiple components, including a housing 21, a support assembly, and a refrigeration assembly 23. The housing 21 can be used to house and protect the internal components; the support assembly may be used to support the refrigeration assembly 23 to reduce the pressure on the refrigeration assembly 23 caused by the deformation of the inner liner 12 during the formation of the insulation layer 15 of the box body 1, thereby protecting and fixing the refrigeration assembly 23; the refrigeration assembly 23 is used to generate cold air.

[0129] The second mounting structure 24 includes a slide groove 241 provided on the support assembly and an avoidance opening 242 provided on the box body 21. The slide rail can pass through the avoidance opening 242 and be engaged with the slide groove 241 of the support assembly. On the one hand, it can realize the connection and positioning of the box body 21 and the support assembly, and at the same time realize the connection and positioning of the box body 21 and the support assembly with the inner liner 12.

[0130] In some embodiments, when the liner 12 is formed by stamping a sheet metal part, as shown in FIG. Figure 14 As shown, the first mounting structure 13 includes a mounting opening 131 and a connector 132 . The connector 132 passes through the mounting opening 131 and protrudes from the inner wall of the box 1 to form a slide rail. The slide rail passes through the avoidance opening 242 and extends into the slide groove 241 .

[0131] The mounting opening 131 is provided on the inner liner 12 . After the inner liner 12 is produced, the connector 132 is inserted into the mounting opening 131 to form a slide rail, thereby reducing production difficulty and production cost.

[0132] In some embodiments, when the inner liner 12 is formed as a plastic piece by absorption, Figure 19 As shown, the slide rail is formed as one piece with the inner wall of the box body 1 and protrudes from the inner wall of the box body 1, wherein the side wall of the inner liner 12 is adsorbed and deformed to form a guide rail protruding from the inner wall of the box body 1. The guide rail protrudes from the inner wall of the inner liner 12, reducing production difficulty and production cost.

[0133] In this embodiment, the first mounting structures 13 with different structures are formed using different materials, thereby reducing the production difficulty and production cost.

[0134] In some embodiments, as Figure 22 As shown, the side wall of the box body 1 is provided with a plurality of first mounting structures 13 spaced apart along the distribution direction of the plurality of cavities, and the refrigeration unit 2 is provided with a second mounting structure 24 for connecting to the first mounting structure 13, and the second mounting structure 24 can be selectively connected to at least one of the plurality of first mounting structures 13.

[0135] The second mounting structure 24 is connected to different first mounting structures 13 so that the refrigeration unit 2 can be located at different positions in the storage compartment 14 , thereby dividing the storage compartment 14 into multiple cavities of different capacities as needed.

[0136] In the embodiment, the first mounting structure 13 is arranged along the distribution direction of the plurality of cavities, so that the refrigeration unit 2 can move along the distribution direction of the plurality of cavities to adjust the capacity of each cavity, thereby increasing the practicability.

[0137] In some embodiments, the box body 21 comprises a front cover plate and a rear cover plate, which define a mounting cabin in which the support assembly and the refrigeration assembly 23 are located, and the front cover plate and the rear cover plate are detachably connected to facilitate the installation and disassembly of the support assembly and the refrigeration assembly 23.

[0139] It can be understood that in the process of forming the heat preservation layer 15 of the cabinet 1, the foaming material expands, and the inner container 12 inevitably deforms towards the inside of the storage compartment 14, and the outer side wall of the support assembly abuts against the inner side wall of the box body 21. In the deformation process of the inner container 12, the support assembly generates a force resisting the deformation force of the inner container 12, which can reduce the deformation amount of the box body 21 and protect and fix the refrigeration assembly 23.

[0140] In some embodiments, as shown in Figure 7 , Figure 8 and Figure 9 , the support assembly comprises a heat insulation piece 221, a support body 222 and an air guide shell 223, the heat insulation piece 221 and the air guide shell 223 are arranged on both sides of the refrigeration assembly 23 along the second direction, and the support body 222 is arranged on the circumferential side of the refrigeration assembly 23 along the first direction and the third direction; the first direction is the normal direction of the opening surface of the storage compartment 14, and the third direction, the first direction and the second direction are perpendicular to each other.

[0145] The first air avoiding opening is arranged in position with the return air opening 212 of the refrigeration unit 2, so that the hot air in the cavity enters the box body 21 through the return air opening 212 to exchange heat with the refrigeration assembly 23; the second air avoiding opening is arranged in position with the supply air opening 211 of the refrigeration unit 2, so that the cold air generated by the refrigeration assembly 23 enters the cavity through the supply air opening 211 to maintain the low temperature in the cavity.

[0147] The sliding groove 241 is arranged on the side walls of the two support pieces 2222 away from each other along the third direction.

[0148] In the present embodiment, the two ends of the connecting piece 2221 abut against the opposite side walls of the two support pieces 2222, and during the process of forming the thermal insulation layer 15 of the box body 1, the connecting piece 2221 can limit the relative movement of the two support pieces 2222, thereby protecting the refrigeration assembly 23.

[0149] The support piece 2222 and the air guide shell 223 cooperate, and during the process of forming the thermal insulation layer 15 of the box body 1, the damage of the refrigeration assembly 23 caused by extrusion in the first direction can be reduced.

[0150] In some embodiments, as shown in Figure 6 , the two support pieces 2222 are designed with pipe fixing holes of the evaporator 231, and the pipe of the evaporator 231 can be clamped in the pipe fixing holes in a concave-convex matching mode to fix the evaporator 231.

[0152] As shown, the guide shell 223 and the refrigeration assembly 23 are located on both sides of the evaporative fan 232 along the second direction, which plays a role in protecting and positioning the evaporative fan 232, and the volute tongue 2231 arranged on the side of the guide shell 223 facing the evaporative fan 232 can play a role in guiding and accelerating the airflow, so as to increase the refrigeration efficiency.

[0153] In some embodiments, the air supply port 211 of the refrigeration unit 2 and the air return port 212 of the refrigeration unit 2 are arranged on different wall surfaces of the box body 21, so as to prolong the circulation path of the cold air sent out from the air supply port 211 and improve the uniformity of the temperature in the cavity.

[0158] In some embodiments, as shown, Figure 9 As shown, the air supply port 211 comprises a plurality of air supply ports 211, and each of the plurality of air supply ports 211 is in communication with the at least two cavities.

[0159] In this embodiment, by providing a plurality of air outlets 211 , the number of air outlets 211 in each cavity is increased, which can increase the speed at which the cold air generated by the refrigeration assembly 23 is discharged into each cavity, thereby increasing the refrigeration efficiency.

[0160] In some embodiments, there are two air outlets 211 , which are respectively arranged on the side walls of the box body 21 opposite to each other along the third direction and close to the top of the box body 21 . Each air outlet 211 is connected to at least two cavities.

[0161] Among them, the two air supply ports 211 are respectively arranged on the side walls of the box body 21 which are arranged opposite to each other along the third direction, and the cold air can be discharged into each cavity from different directions. The air supply ports 211 are close to the top of the box body 21, so that the cold air discharged from the air supply ports 211 can naturally drop in the cavity, which can improve the temperature uniformity and cooling efficiency in each cavity and reduce energy consumption.

[0162] In some embodiments, the storage device further includes a controller and multiple temperature sensors, the multiple temperature sensors are connected to the controller, at least one temperature sensor is provided in each cavity, and the controller is connected to the refrigeration unit 2.

After the production and assembly of the refrigeration component 23 assembly is completed, the refrigeration component 23 assembly production line intersects with the box body 1 production line, the refrigeration component 23 assembly is assembled with the box body 1, and then the return air pipe group 233 and the rear cover of the box body 21 are sequentially installed into the box body 1, that is, the assembly of the refrigeration component 23 assembly is separated from the production line of the storage equipment, and the multiple beats of assembling multiple refrigeration components with the box body 1 are changed into the assembly of four assemblies of the refrigeration component 23 assembly, the return air pipe group 233, the rear cover of the box body 21 and the box body 1. Therefore, compared with a production line in which multiple components are assembled in sequence into a storage device, the two sub-production lines of the refrigeration component 23 assembly and the box body 1 are produced in parallel and simultaneously, and then the assembly plan of the four assemblies is carried out, which improves production efficiency and saves production beats and personnel.
