The cabinet defines a storage compartment, which can include a refrigeration compartment, a freezing compartment, or a variable temperature compartment.

[0064] As shown in Figure 1 , Figure 12 and Figure 23 , the storage device provided by the application includes a cabinet 1, a door body 4, a refrigeration unit 2, and an air duct structure; the cabinet 1 defines a storage compartment 14; the door body 4 is pivotally mounted on the cabinet 1 and used for closing the storage compartment 14; the refrigeration unit 2 is arranged in the storage compartment 14 and separates the storage compartment 14 into multiple cavities; the air duct structure is mounted on the cabinet 1 and has an air inlet 341 and multiple air outlet groups, the air inlet 341 is in communication with the refrigeration unit 2, and the multiple air outlet groups are in one-to-one correspondence with the multiple cavities and are selectively in communication with the multiple cavities.

[0065] The door body 4 can be connected to the side wall of the cabinet 1 in a pivot structure, and the door body 4 can be opened or closed relative to the cabinet 1 to close or open the storage compartment 14.

[0066] The storage compartment 14 can be separated by the refrigeration unit 2 into two or more cavities, and the multiple cavities are isolated so that different cavities have different temperatures to meet the storage requirements of items with different temperature requirements.

[0067] The refrigeration unit 2 can include multiple refrigeration sub-units, the multiple refrigeration sub-units can separate the storage compartment 14 into three or more cavities, and the multiple refrigeration sub-units can share a set of refrigeration components 23; or the refrigeration unit 2 is an integral whole, and the refrigeration unit 2 can separate the storage compartment 14 into a first compartment 141 and a second compartment 142.

[0068] The refrigeration unit 2 is used for generating cold air to maintain the low temperature of the storage compartment 14, the refrigeration unit 2 includes an evaporator 231 and a fan and the like refrigeration components 23, the refrigeration unit 2 has an air supply port 211 and an air return port 212, and the air supply port 211 and the air return port 212 are in communication with at least two cavities to realize the circulation of cold air in the storage compartment 14.

[0069] The refrigeration unit 2 can be put into 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.

[0070] The plurality of cavities are independent of each other, and the plurality of cavities can all be refrigeration compartments, or all be freezing compartments, or part of the plurality of cavities are refrigeration compartments and the other part are freezing compartments.

[0071] The air duct structure is used for connecting the refrigeration unit 2 and the plurality of cavities, and an air duct cavity 34 is formed in the air duct structure. The air duct cavity 34 is connected with the refrigeration unit 2 through an air inlet 341, and the air duct cavity 34 is selectively connected with the cavities through a plurality of air outlets.

[0072] The air inlet 341 and the plurality of air outlet groups form a plurality of ventilation paths in parallel, and the plurality of ventilation paths are connected with the plurality of cavities in one-to-one correspondence. A fluid valve is arranged in the ventilation path, and the fluid valve can be a ball valve or a damper structure. The fluid valve is used for controlling the connection or disconnection of the ventilation path, and can also control the cross-sectional area of the ventilation path to control the fluid flow.

[0073] In the embodiment, each cavity is connected with the refrigeration unit 2 through one of the plurality of air outlet groups. The amount of cold air entering the cavity can be controlled by controlling the connection and disconnection of the air outlet group and the corresponding cavity, so as to realize the individual control of the temperature of the cavity.

[0074] The air duct structure can be a structural member with an air duct cover plate and an air duct pre-embedded cavity, and the air duct structure can have at least the following installation positions:

[0075] Firstly, the air duct structure is installed outside the cabinet 1, for example, is installed at the open end of the cabinet 1. The air duct structure is arranged around the circumference of the cabinet 1, and the air duct structure and the cabinet 1 jointly define the storage compartment 14, thereby increasing the volume of the storage compartment 14.

[0076] Secondly, the air duct structure is installed between the inner container 12 and the outer shell 11 of the cabinet 1, that is, the air duct structure is located outside the storage compartment 14, thereby reducing the occupation of the volume of the storage compartment 14.

[0077] Thirdly, the air duct structure is installed on the inner wall of the cabinet 1, and the air duct structure is located in the storage compartment 14. The installation of the air duct structure can be performed after the assembly of the cabinet 1 is completed, and the installation process is simple.

[0078] In the related art, most horizontal air-cooled freezers are single-temperature-zone products. In order to reduce the occupation of the storage compartment, the refrigeration unit is usually installed on one side of the cabinet, and the air supply port of the refrigeration unit is directly communicated with the storage compartment or communicated with the storage compartment through an air duct structure. The user can control the temperature of the storage compartment by controlling the refrigerating capacity of the refrigeration unit. The freezer provided with multiple temperature zones usually has multiple evaporators and capillary tubes, forming multiple refrigerant circulation systems, so as to realize temperature adjustment of multiple temperature zones.

[0079] However, in the case of a certain cabinet volume, the circulation system increased for realizing multi-temperature-zone control will inevitably occupy the effective volume of the cabinet.

[0080] According to the storage equipment provided in the embodiments of the present application, the refrigeration unit 2 can separate the storage compartment 14 into multiple cavities, and the multiple cavities are not communicated with each other. The air duct structure can communicate the multiple cavities with the refrigeration unit 2 respectively. By controlling the communication relationship between each air outlet group in the air duct structure and the corresponding cavity, the amount of cold air entering each cavity can be controlled, so as to realize individual temperature control of each cavity. In other words, one set of circulation system can be used to realize individual temperature control of multiple cavities, without the need to increase refrigeration devices such as evaporators and capillary tubes, which can realize individual temperature control of multiple cavities and reduce the occupation of the effective volume of the cabinet 1.

[0081] In some embodiments, as shown in Figure 23 The air inlet 341 and the multiple air outlet groups form multiple ventilation paths. The storage equipment further includes multiple dampers 5, which are rotatably arranged in the multiple ventilation paths and are configured to be individually controlled.

[0082] The damper 5 can include a door leaf and a driving member. The driving member can rotate the door leaf in the ventilation path. In the case that the normal line of the door leaf intersects the flow direction of the cold air in the ventilation path, the ventilation path is unobstructed and the cold air can flow through the ventilation path. In the case that the normal line of the door leaf is perpendicular to the flow direction of the cold air in the ventilation path, the flow of the cold air in the ventilation path is the largest. In the case that the normal line of the door leaf is parallel to the flow direction of the cold air in the ventilation path, the ventilation path is blocked and the cold air cannot flow into the cavity connected to the ventilation path through the ventilation path.

[0083] In the present embodiment, the damper 5 is arranged in each ventilation path. The state of the damper 5 can be controlled to control the communication, disconnection or flow area of each ventilation path, so as to individually control the amount of cold air entering each cavity, and further realize individual temperature control of multiple cavities, which is simple in structure and easy to implement.

[0084] In some embodiments, as shown in Figure 24As shown, the plurality of cavities include a first chamber 141 and a second chamber 142, which are located on both sides of the refrigeration unit 2.

[0085] The refrigeration unit 2 divides the storage chamber 14 into the first chamber 141 and the second chamber 142, which can both be refrigeration chambers, both be freezing chambers, or one be a refrigeration chamber and the other be a freezing chamber.

[0086] The air duct structure includes a first portion 343 and a second portion 344, the first portion 343 has a first air outlet group in communication with the first chamber 141, and the second portion 344 has a second air outlet group in communication with the second chamber 142; the air door 5 includes a first door 51 and a second door 52, the air inlet 341 is located between the first door 51 and the second door 52, the first door 51 is configured to control the communication and disconnection of the air inlet 341 with the first air outlet group, and the second door 52 is configured to control the communication and disconnection of the air inlet 341 with the second air outlet group.

[0087] The sizes of the first portion 343 and the second portion 344 can be determined according to the placement position of the refrigeration unit 2.

[0088] When the air duct structure is located at the end of the cabinet 1 and extends around the circumference of the cabinet 1, and the refrigeration unit 2 is located in the middle of the storage chamber 14, the first portion 343 and the second portion 344 are the same; when the refrigeration unit 2 is placed on one side of the storage chamber 14, the first portion 343 is larger or smaller than the second portion 344.

[0089] The first air outlet group can have at least one air outlet 342, for example, 3, 4 or more, which can be determined according to the volume of the first chamber 141. A ventilation path is formed between the first air outlet group and the air inlet 341, the first door 51 is located in the ventilation path between the first air outlet group and the air inlet 341, and the first door 51 is used to control the amount of cold air entering the first chamber 141.

[0090] The second air outlet group can have at least one air outlet 342, for example, 3, 4 or more, which can be determined according to the volume of the second chamber 142. Another ventilation path is formed between the second air outlet group and the air inlet 341, the second door 52 is located in the ventilation path between the second air outlet group and the air inlet 341, and the second door 52 is used to control the amount of cold air entering the second chamber 142.

[0091] The air inlet 341 is located between the first door 51 and the second door 52, and the first door 51 and the second door 52 can be controlled separately, for example, the first door 51 and the second door 52 can both be in an open state to communicate the ventilation path, or the first door 51 and the second door 52 can both be in a closed state to disconnect the ventilation path, or the first door 51 and the second door 52 can be in an open state and a closed state respectively.

[0092] For example, the first door 51 and the second door 52 are arranged on both sides of the air inlet 341, and in the case that the temperature of the first chamber 141 needs to be reduced, the first door 51 can be controlled to rotate to communicate the air inlet 341 with the first air outlet group; in the case that the temperature of the first chamber 141 reaches a set value and does not need to be reduced, the first door 51 can be controlled to rotate in the opposite direction to disconnect the air inlet 341 from the first air outlet group.

[0093] In some embodiments, as shown in Figure 25 and Figure 26 The door body 4 can be split, and the door body 4 includes a plurality of sub-doors which are pivotally arranged at the open ends of the cavities one by one, so as to reduce the temperature interference between the cavities when the door body 4 is opened; or the door body 4 can be a whole, and the inner wall of the door body 4 is provided with a plurality of abutting portions which are arranged one by one with the sub-doors, and in the case that the door body 4 covers the cabinet 1, the abutting portion abuts against the end of the cavity to close the open end of the cavity, so that the plurality of cavities can be opened at one time, and the taking of objects is facilitated.

[0094] In some embodiments, the air duct structure is the cabinet opening 3, and the air duct structure is integrated with the cabinet opening 3, and the air duct cavity 34 is arranged in the cabinet opening 3.

[0095] The cabinet opening 3 is used to connect the cabinet 1 and the door body 4, and the cabinet opening 3 is arranged at the open end of the cabinet 1 around the circumference of the cabinet 1, and the air duct cavity 34 is located in the cabinet opening 3, so that the integration of the air duct structure and the cabinet opening 3 is realized, and the conventional air duct cover plate and the air duct cavity 34 embedded part are cancelled, and the structure design is simple, the process is simple, and the overall cost is reduced.

[0096] The cabinet opening 3 can be integrally injection molded or formed by sheet metal stamping and bending. The cabinet opening 3 can be connected to the cabinet 1 by one or more of plug-in connection, buckle connection and screw connection.

[0097] The cabinet opening 3 is connected with the open end of the cabinet body 1 and extends around the circumference of the cabinet body 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 air outlets. In the case of multiple air outlets 342, the multiple air outlets 342 are arranged at intervals along the extension direction of the air duct cavity 34, that is, the multiple air outlets 342 are arranged around the circumference of the storage compartment 14. The multiple air outlets 342 can realize cold air output, and the four-side air cooling can improve the refrigeration efficiency and the uniformity of the temperature in the storage equipment.

[0098] In the related art, the air-cooled refrigerator has high cost in the air duct structure. The air duct structure mainly includes an air duct cover plate and an air duct pre-embedded cavity, which increases the number of parts of the storage equipment and prolongs the production cycle.

[0099] 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. The air duct cavity 34 can be connected with the refrigeration unit 2 and multiple cavities, which realizes the integration of the air duct structure and the cabinet opening 3, cancels the conventional air duct cover plate and the air duct cavity 34 pre-embedded part, and has simple structure design, simple process and low overall cost, which reduces the production cycle and improves the production efficiency.

[0100] In some embodiments, as shown in Figure 1 The cabinet body 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.

[0101] The cabinet opening 3 has an open end. The open end of the cabinet opening 3 is connected with the end of the inner container 12. 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. Compared with producing a closed air duct cavity 34 on the cabinet opening 3, producing an air duct cavity 34 with part of the wall surface 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.

[0102] The air duct cavity 34 is defined by the inner container 12 and the cabinet opening 3. The cabinet opening 3 with the open end simplifies the production difficulty and reduces the cost compared with the cabinet opening 3 with the closed air duct cavity 34.

[0103] 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 connected in sequence and relatively bent. The cabinet opening 3 includes a first wall 31, a top wall, and a second wall 33 connected in sequence. The first wall 31 is located on the inner side of the second wall 33 and is spaced apart from the second wall 33. The first wall 31 and the second wall 33 are 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.

[0104] The end face of the open end of the inner container 12 forms at least two bending sections, which can be continuously bent towards the inner side of the storage compartment 14 or continuously bent away from the storage compartment 14. The first wall 31, the top wall, the second wall 33 and part of the at least two bending sections jointly define an air duct cavity 34, that is, the inner container 12 and the cabinet opening 3 jointly define the air duct cavity 34.

[0105] In the embodiment, the at least two bending sections connected in sequence and bent relative to each other can be integrally formed. By arranging the first wall 31 and the second wall 33 to be connected to different sections of the at least two bending sections, multi-point connection is achieved, which can increase the stability of the connection between the cabinet opening 3 and the cabinet 1, and at the same time, the air duct cavity 34 can be formed.

[0106] The inner container 12 can be made of at least the following two materials:

[0107] First, the inner container 12 can be a plastic part, and the material of the plastic part can be a PS or ABS plate. The inner container 12 can be integrally formed by adsorption.

[0108] In the embodiment, as shown in Figure 20 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 outward relative to the side wall of the inner container 12. The second section 1222 is bent upward relative to the first section 1221. The third section 1223 is bent outward relative to the second section 1222. The fourth section 1224 is bent upward 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. The fourth section 1224 is connected to the second wall 33.

[0109] 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 of the recess and the side wall facing the storage compartment 14 are open. At least part of the first wall 31 is located in the recess. 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.

[0110] The bottom wall of the first wall 31 can abut or be connected to the first section 1221. The first section 1221 supports the first wall 31, which increases the stability of the connection between the cabinet opening 3 and the cabinet 1.

[0111] 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, which increases the stability of the connection between the cabinet opening 3 and the cabinet 1.

[0112] When the fourth section 1224 is connected to the inner wall of the second wall 33 , the third section 1223 as a whole forms the bottom wall of the air duct cavity 34 , which can reduce the encroachment of the second wall 33 on the air duct cavity 34 and improve the ventilation efficiency of the air duct cavity 34 .

[0113] When 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 , thereby increasing the stability of the connection between the cabinet opening 3 and the box body 1 .

[0114] In some embodiments, as Figure 20 and Figure 21 As shown, 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 snap-fitted; 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 snap-fitted.

[0116] In this embodiment, the first wall 31 and the second wall 33 are respectively engaged with the inner container 12 , thereby increasing the stability of the connection between the cabinet opening 3 and the inner container 12 and achieving a quick connection.

[0117] The connection structure between the first connection structure 1231 and the second connection structure 1232 and the connection structure between the third connection structure 1233 and the fourth connection structure 1235 may be the same as or different from each other.

[0118] In some embodiments, one of the first connection structure 1231 and the second connection structure 1231 is a slot structure or a hole structure, and the other of the first connection structure 1231 and the second connection structure 1231 is a slider. The open end of the slot structure faces the storage compartment 14, and the slider has a connecting surface and a guide surface, and the guide surface is arranged at an acute angle with the connecting surface.

[0119] For example, Figure 21As shown, the first connecting structure 1231 is a groove structure or a hole structure, and the second connecting structure 1232 is a sliding block having a connecting clamping surface and a guiding surface. The guiding surface is arranged at an acute angle with the first wall 31 to facilitate the sliding of the second connecting structure 1232 into the groove structure or the hole structure. 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 off from the first connecting structure 1231.

[0120] 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 having a connecting clamping surface and a guiding surface. The guiding surface is arranged at an obtuse angle with the second section 1222 to facilitate the sliding of the first connecting structure 1231 into the groove structure or the hole structure. 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 off from the second connecting structure 1232.

[0121] 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.

[0122] In the embodiment, as shown in Figure 16 and Figure 17 , the at least two bending sections include a fifth section 1225 and a sixth section 1226. The fifth section 1225 is bent outward relative to the side wall of the inner container 12, and the sixth section 1226 is bent upward relative to the fifth section 1225. The fifth section 1225 forms part of the wall surface of the air duct cavity 34, and the fifth section 1225 is connected with the first wall 31.

Part of the fifth section 1225 forms part of the wall surface of the air duct cavity 34.

[0124] It should be noted that fewer bending sections are arranged on the sheet metal part, which can reduce the damage to the structural strength and reduce the number of stamping of the sheet metal, thereby reducing the production cost and difficulty.

[0125] In some embodiments, as shown in Figure 14 and Figure 15 , the inner container 12 further includes a corner sealing member 129. The corner sealing member 129 is arranged at a gap 1227 at the corner of the adjacent two walls of the open end of the inner container 12. The corner sealing member 129 is connected with the cabinet opening 3 and the inner container 12, respectively. Part of the wall surface of the corner sealing member 129 is used to form part of the wall surface of the air duct cavity 34.

[0126] It can be understood that the end of the inner container 12 is formed with a gap 1227 at the corner of the adjacent two walls during the stamping and bending process, and the corner seal 129 is used to connect the adjacent two walls to fill the gap 1227, and the corner seal 129, the inner container 12 and the cabinet opening 3 jointly define the air duct cavity 34.

[0127] The corner seal 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 the specific installation can be carried out according to the actual structure.

[0128] The projection of the corner seal 129 has a coinciding part with the projection of the open end of the inner container 12 in the first direction as the projection direction, and the corner seal 129 is connected with the cabinet opening 3 and the inner container 12 respectively to increase the stability of the connection of the three.

[0129] In some embodiments, as shown in Figure 15 The corner seal 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 segment 1225, and the third face 1293 is connected with the sixth segment 1226.

[0130] As shown in Figure 15 and Figure 16 The second face 1292 and the fifth segment 1225 are provided with a first through hole 1294, the first wall 31 is provided with a connecting part 311, the connecting part 311 is inserted into the first through hole 1294; or, the third face 1293 and the sixth segment 1226 are provided with a second through hole 1295, the second wall 33 is provided with a fifth connecting structure 1236, the fifth connecting structure 1236 is clamped with the second through hole 1295; or, the second face 1292 and the fifth segment 1225 are provided with a first through hole 1294, the first wall 31 is provided with a connecting part 311, the connecting part 311 is inserted into the first through hole 1294, and the third face 1293 and the sixth segment 1226 are provided with a second through hole 1295, and the fifth connecting structure 1236 is clamped with the second through hole 1295.

[0131] The fifth connecting structure 1236 is a sliding block, the sliding block has a clamping face and a guide face connected with each other, the guide face is arranged at an obtuse angle with the second wall 33 to make the fifth connecting structure 1236 smoothly slide into the second through hole 1295, and the clamping face is arranged at a right angle or an acute angle with the second wall 33, the clamping face is clamped with the second through hole 1295 to reduce the risk of the fifth connecting structure 1236 falling off from the second through hole 1295.

[0132] In some embodiments, as shown in Figure 16 and Figure 18As shown, the first wall 31 is arranged in the storage compartment 14 and is provided with a plurality of air outlets 342, each of which is in communication with at least two cavities, and the second wall 33 is arranged outside the storage compartment 14 and is provided with a reinforcing rib 331.

[0133] As shown, the second wall 33 is provided with a reinforcing rib 331, which can increase the structural strength of the cabinet opening 3; and the plurality of air outlets 342 are arranged along the extension direction of the first wall 31 to achieve four-way air supply of the storage compartment 14, thereby improving the refrigeration effect and efficiency and improving the temperature uniformity. Figure 20

[0134] 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.

[0135] In some embodiments, the cabinet 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.

[0136] 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 by 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 by plug-in connection and clamping connection.

[0137] It should be noted that the production line of the storage equipment 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 equipment, and the assembly of multiple refrigeration components with the cabinet 1 is changed to 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 equipment, 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, thereby improving the production efficiency and saving the production rhythm and personnel.

[0138] ​In the related art, the production line of the storage device is a production line in which all parts of the storage device are sequentially assembled, each part has a respective station, and multiple parts need to be sequentially assembled by machines or personnel according to an installation rhythm to complete the production of a storage device. When the production line of the storage device is at a certain installation rhythm, the machines or personnel of other numerous installation stations are idle, causing waste of machines, personnel, and rhythm.

[0139] 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 part in the refrigeration unit 2 is separated from the production line of the storage device, and the multiple rhythms of assembling multiple refrigeration parts with the cabinet 1 become the assembly of two assemblies of the refrigeration unit 2 assembly and the cabinet 1, thereby improving the production efficiency and saving the production rhythm and personnel.

[0140] In some embodiments, as shown in Figure 2 The cabinet 1 includes an outer shell 11, an inner container 12, and a thermal insulation layer 15 located between the outer shell 11 and the inner container 12. The cabinet 1 is configured to form the thermal insulation layer 15 between the outer shell 11 and the inner container 12 after the refrigeration unit 2 is installed in the inner container 12.

[0141] In the production line of the cabinet 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 cabinet 1, and the refrigeration unit 2 is assembled with the cabinet 1. After the refrigeration unit 2 is assembled with the inner container 12, the rhythm of forming the thermal insulation layer 15 between the outer shell 11 and the inner container 12 is performed.

[0142] In the present embodiment, since the gas return 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 thermal insulation material is filled between the outer shell 11 and the inner container 12. This can allow part of the gas return pipe group 233 to be located in the thermal insulation layer 15. The thermal insulation layer 15 can protect and fix part of the gas return pipe group 233 located therein, and reduce the occupation of the storage compartment 14, while simplifying the assembly process of the cabinet 1 and the refrigeration unit 2.

[0143] In some embodiments, as shown in Figure 2 , Figure 11 and Figure 14 The cabinet 1 includes an outer shell 11, an inner container 12, and a thermal insulation 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 includes a gas return pipe group 233, one end of the gas return pipe group 233 being used to pass through the through hole 121 and the thermal insulation layer 15 to communicate with the compressor.

[0144] The return air pipe group 233 is used to communicate the evaporator 231 and the compressor, and 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 refrigeration unit 2 is assembled with the cabinet 1, the gap between the outer shell 11 and the inner container 12 is filled with thermal insulation material to form a thermal insulation layer 15. Part of the return air pipe group 233 between the outer shell 11 and the inner container 12 is embedded in the thermal insulation layer 15. The thermal insulation layer 15 can protect and fix part of the return air pipe group 233 located therein.

[0145] In some embodiments, as shown in Figure 4 and Figure 13 The first mounting structure 13 and the second mounting structure 24 extend along a first direction, which is the normal direction of the opening surface of the storage compartment 14.

[0146] The first mounting structure 13 and the second mounting structure 24 extend along a direction perpendicular to the opening surface of the storage compartment 14.

[0147] In the present 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. The first mounting structure 13 and the second mounting structure 24 extending along the first direction can reduce the interference with the movement of the refrigeration unit 2, facilitate assembly, extend 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 cabinet 1.

[0148] The first mounting structure 13 and the second mounting structure 24 at least include the following three structures:

[0149] First, 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.

[0150] The first mounting structure 13 includes the sliding groove 241, and the second mounting structure 24 includes the sliding rail; or the second mounting structure 24 includes the sliding groove 241, and the first mounting structure 13 includes the sliding rail.

[0151] The sliding groove 241 extends to the end of the device, that is, one end of the sliding groove 241 is open, so that the sliding rail is inserted from the open end of the sliding groove 241, and the assembly convenience of the refrigeration unit 2 and the storage compartment 14 is improved.

[0152] The first mounting structure 13 and the second mounting structure 24 are connected in a sliding groove 241 sliding rail matching mode, 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 a first direction.

[0153] Secondly, the first mounting structure 13 is arranged on the inner bottom wall of the cabinet 1, the second mounting structure 24 is arranged on the bottom wall of the refrigeration unit 2, one of the first mounting structure 13 and the second mounting structure 24 comprises a sliding groove, and the other of the first mounting structure 13 and the second mounting structure 24 comprises a sliding rail matched with the sliding groove 241, in the process of inserting the refrigeration unit 2 into the storage compartment 14, the sliding rail extends into the sliding groove, and the sliding groove is clamped with the sliding rail.

[0154] Thirdly, the above two connection modes are combined.

[0155] In some embodiments, the refrigeration unit 2 comprises a box body 21, a support assembly arranged in the box body 21, and a refrigeration assembly 23; the second mounting structure 24 comprises 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; and the first mounting structure 13 comprises a sliding rail.

[0156] Among them, the refrigeration unit 2 integrates a plurality of components including the box body 21, the support assembly and the refrigeration assembly 23. The box body 21 can be used to accommodate and protect the internal components; the support assembly can be used to support the refrigeration assembly 23 to reduce the extrusion force of the refrigeration assembly 23 caused by the deformation of the inner container 12 in the process of forming the heat preservation layer 15 of the cabinet 1, and to protect and fix the refrigeration assembly 23; and the refrigeration assembly 23 is used to generate cold air.

[0157] The second mounting structure 24 comprises a sliding groove 241 arranged on the support assembly and an avoiding opening 242 arranged on the box body 21, and the sliding rail can be clamped with the sliding groove 241 of the support assembly through the avoiding opening 242, which can realize the connection and positioning of the box body 21 and the support assembly, and realize the connection and positioning of the box body 21, the support assembly and the inner container 12.

[0158] In some embodiments, when the inner container 12 is formed by stamping a sheet metal part, as shown in Figure 14 The first mounting structure 13 comprises a mounting opening 131 and a plug-in part 132, the plug-in part 132 penetrates the mounting opening 131 and protrudes from the inner wall of the cabinet 1 to form a sliding rail, and the sliding rail penetrates the avoiding opening 242 and extends into the sliding groove 241.

[0159] Among them, the mounting opening 131 is arranged on the inner container 12, and after the production of the inner container 12 is completed, the plug-in part 132 is inserted into the mounting opening 131 to form the sliding rail, thereby reducing the production difficulty and cost.

[0160] In some embodiments, as shown in FIG. 1, the inner container 12 is integrally formed with the box 1, and the slide rail is integrally formed with the inner wall of the box 1 and protrudes from the inner wall of the box 1. In this case, the side wall of the inner container 12 is deformed by suction to form the slide rail that protrudes from the inner wall of the inner container 12. This reduces the difficulty and cost of production. Figure 19

[0161] In this embodiment, the first mounting structure 13 is formed of different materials to have different structures, which reduces the difficulty and cost of production.

[0162] In some embodiments, as shown in FIG. 1, the side wall of the box 1 is provided with a plurality of first mounting structures 13 that are spaced apart along the distribution direction of the plurality of cavities. The refrigeration unit 2 is provided with a second mounting structure 24 that is configured to be connected to the first mounting structure 13. The second mounting structure 24 is selectively connected to at least one of the plurality of first mounting structures 13. Figure 22

[0163] In this case, 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. Thus, the storage compartment 14 can be divided into a plurality of cavities with different capacities according to the needs.

[0164] In this embodiment, the plurality of first mounting structures 13 are spaced apart along the distribution direction of the plurality of cavities, so that the refrigeration unit 2 can be moved along the distribution direction of the plurality of cavities to adjust the capacity of each cavity, thereby increasing the practicability.

[0165] In some embodiments, as shown in FIG. 1, the refrigeration unit 2 includes a box body 21, a support assembly, and a refrigeration assembly 23. The support assembly is arranged in the box body 21, and the refrigeration assembly 23 is mounted on the support assembly. The outer side wall of the support assembly abuts against the inner side wall of the box body 21. Figure 2 Figure 3 It can be understood that, in the process of forming the thermal insulation layer 15 of the box 1, the foaming material expands, and the inner container 12 inevitably deforms towards the inside of the storage compartment 14. The outer side wall of the support assembly abuts against the inner side wall of the box body 21. In the process of deforming the inner container 12, the support assembly generates a force that resists the deforming force of the inner container 12, thereby reducing the deformation amount of the box body 21 and protecting and fixing the refrigeration assembly 23.

[0166] In some embodiments, as shown in FIG. 1, the refrigeration unit 2 includes a box body 21, a support assembly, and a refrigeration assembly 23. The support assembly is arranged in the box body 21, and the refrigeration assembly 23 is mounted on the support assembly. The outer side wall of the support assembly abuts against the inner side wall of the box body 21.

Figure 7 Figure 8 Figure 9 ​​​​​As shown, the support assembly includes a heat insulation member 221, a support body 222, and an air guide shell 223. The heat insulation member 221 and the air guide shell 223 are arranged on two 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.

[0168] The second direction is the direction in which the plurality of cavities are distributed, and the third direction is the direction intersecting the distribution direction of the plurality of cavities.

[0169] In this embodiment, at least two cavities are distributed along the second direction, and the refrigeration unit 2 is located between the adjacent two cavities. The heat insulation member 221, the support body 222, and the air guide shell 223 are distributed in the upper, lower, left, right, front, and rear directions of the refrigeration assembly 23 to further protect the refrigeration assembly 23 during the formation of the heat preservation layer 15 of the cabinet 1.

[0170] The heat insulation member 221 plays a role of heat insulation and heat preservation. In the case of isolating the plurality of cavities for individual temperature control, the heat insulation member 221 can isolate the temperature of the adjacent two cavities and reduce the temperature interference between the adjacent two cavities.

[0173] In some embodiments, the heat insulation member 221 is arranged between the refrigeration assembly 23 and the box body 21. The heat insulation member 221 is provided with a first air avoiding opening and a second air avoiding opening. The return air opening 212 of the refrigeration unit 2 communicates the first air avoiding opening with the storage compartment 14, and the supply air opening 211 of the refrigeration unit 2 communicates the second air avoiding opening with the storage compartment 14.

[0174] The first air avoiding opening is arranged in position with the return air opening 212 of the refrigeration unit 2 to enable the hot air in the cavity to enter 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 to enable the cold air generated by the refrigeration assembly 23 to enter the cavity through the supply air opening 211 to maintain the low temperature in the cavity.

[0175] In some embodiments, asFigure 6 As shown, the support body 222 includes a connecting piece 2221 and two support pieces 2222 located on both sides of the connecting piece 2221 along the third direction, the two support pieces 2222 are located on both sides of the refrigeration assembly 23 along the third direction, and the connecting piece 2221 is arranged at the end of the refrigeration unit 2 along the first direction; the support piece 2222 is connected with the inner side wall of the box body 21.

[0176] Among them, the chute 241 is arranged on the opposite side walls of the two support pieces 2222 along the third direction.

[0177] In this 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 heat preservation layer 15 of the cabinet 1, the connecting piece 2221 can limit the relative movement of the two support pieces 2222, thereby protecting the refrigeration assembly 23.

[0178] The support piece 2222 and the air guide shell 223 cooperate, and during the process of forming the heat preservation layer 15 of the cabinet 1, the damage of the refrigeration assembly 23 caused by extrusion in the first direction can be reduced.

[0179] 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 pipes of the evaporator 231 can be clamped in the pipe fixing holes in a concave-convex matching mode to fix the evaporator 231.

[0180] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 8 , the refrigeration assembly 23 further includes an evaporative fan 232; the air guide shell 223 is arranged on the side of the refrigeration assembly 23 away from the heat insulation piece 221 along the second direction, and the air guide shell 223 and the heat insulation piece 221 define a mounting position, and the evaporative fan 232 is mounted in the mounting position; the side of the air guide shell 223 facing the evaporative fan 232 is provided with a volute tongue 2231.
