Detailed Description of the Embodiment

[0036] The present application will be described in detail below with reference to the specific embodiments shown in the drawings.

[0037] In each drawing of the present application, for the convenience of illustration, the dimensions of some structures or parts are enlarged relative to other structures or parts. Therefore, it is only used to illustrate the basic structure of the subject matter of the present application.

[0038] It should be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, structures or parameters, the objects described by these terms should not be limited by these terms. These terms are only used to distinguish these described objects from each other.

[0039] Referring Figures 1 to 3 as shown in FIG. Figures 1 to 3 , an embodiment of the present application provides a refrigeration equipment 100, including a box body 1, a door body 2 and a refrigeration unit. The box body 1 has a storage compartment 3, and the storage compartment 3 has an opening. The door body 2 is used to open or close the opening of the storage compartment 3.

[0040] The refrigeration device 100 in this embodiment is a direct-cooling refrigeration device, that is, it uses the direct-cooling method to supply cold to the items stored in the storage compartment 3. The refrigeration device 100 can be specifically set as a refrigerator, a freezer, a wine cabinet, etc., especially a refrigeration device with a large volume. In this embodiment, the refrigeration device 100 is taken as a horizontal freezer as an example for description.

[0041] Specifically, the refrigeration unit includes a compressor, a condenser, a throttling device, and an evaporator connected in sequence.

[0042] Combined with Figures 4 to 5 , the box body 1 includes an inner container 11 and a box shell 12 arranged outside the inner container 11. The inner container 11 defines the storage compartment 3. The evaporator includes an evaporation pipe 4 wound around the outer periphery of the inner container 11. The evaporation pipe 4 transfers the cold quantity to the inside of the storage compartment 3 through the inner container 11 by means of natural radiation, so as to refrigerate the items stored in the storage compartment 3.

[0043] In this natural radiation refrigeration method where the evaporation pipe 4 is wound around the outer periphery of the inner container 11, the cold quantity is transferred from the inner container 11 to the middle area of the storage compartment 3. However, the space in the storage compartment 3 is usually large, which will cause a large temperature difference in each area of the storage compartment 3 and poor temperature uniformity. Moreover, the storage compartment 3 has an opening. Especially when the door body 2 is opened, a large amount of cold quantity at the opening of the storage compartment 3 is dissipated outward, which will cause the temperature in the area near the opening of the storage compartment 3 to be significantly higher than that in the area near the inner container 11, further exacerbating the uneven temperature in the storage compartment 3.

[0044] Refer to Figure 2 and Figure 4 , the refrigeration device 100 further includes an air duct assembly 5. The air duct assembly 5 is arranged in the storage compartment 3 and is connected to the inner container 11, so that the cold quantity generated by the evaporation pipe 4 can be conveyed to the area in the storage compartment 3 far from the inner container 11 through the air duct assembly 5, thereby improving the temperature uniformity in the storage compartment 3.

[0045] Refer to Figures 6 to 14 , the air duct assembly 5 includes a housing 51 and a mounting structure. The mounting structure is used to mount the air duct assembly 5 on the inner container 11. The housing 51 has an air duct, and through the air duct, the cold quantity generated by the evaporation pipe 4 can be conveyed to the area in the storage compartment 3 far from the inner container 11.

[0046] Refer to Figures 9 to 12 , the mounting structure includes a mounting seat 52, a mating part 53, and a mating hole 54 penetrating through the housing 51.

[0047] The mounting base 52 is provided outside the housing 51, and a mating groove 521 is provided on the mounting base 52 corresponding to the mating hole 54. The mating member 53 has a mating portion 531. The mating member 53 has a first position and a second position, and the mating member 53 is movable between the first position and the second position. When the mating member 53 is in the first position, the mating portion 531 is located inside the housing 51. When the mating member 53 is in the second position, the mating portion 531 extends out of the mating hole 54 and mates with the mating groove 521.

[0048] Through the mounting structure, the housing 51 can be assembled with the inner container 11 through the mounting base 52. In this way, when the mating member 53 is in the first position, the housing 51 can be separated from the mounting base 52, so that the housing 51 can be disassembled and replaced. When the mating member 53 is in the second position, the mating portion 531 passes through the mating hole 54 on the housing 51 and mates with the mating groove 521 of the mounting base 52, thereby restricting the relative movement of the housing 51 with respect to the mounting base 52. During installation, when the mating member 53 is in the first position, the housing 51 can be placed at a preset installation position, and then the mating member 53 is moved to the second position, so that the housing 51 and the mounting base 52 can be relatively fixed. When disassembling the housing 51, the mating member 53 is moved from the second position to the first position, and the housing 51 can be disassembled. In this way, the installation and fixation of the housing 51 and the non-destructive disassembly and replacement can be realized, and the operation is simple.

[0049] See Figures 10 to 14 , wherein, the mounting base 52 includes an air duct connecting plate 522 and an inner container connecting plate 523. The mating groove 521 is provided on the air duct connecting plate 522, and the air duct connecting plate 522 and the inner container connecting plate 523 are arranged at an angle. The inner container connecting plate 523 is connected to the inner container 11. In this way, when the housing 51 is mated with the mounting base 52, the connection between the housing 51 and the inner container 11 is realized.

[0050] See Figure 2 and Figure 4, the refrigeration device 100 further includes a return air member 6, and the air duct assembly 5 is connected to the inner container 11 through the return air member 6. The return air member 6 is connected to the inner container 11, and a heat exchange channel is formed between the return air member 6 and the inner container 11. The heat exchange channel, the air duct, and the storage compartment 3 are sequentially connected and form a circulating air path. Since the air outlet 511 of the air duct is provided at the opening of the housing 51 close to the storage compartment 3, the cold generated by the evaporation pipe 4 can be transmitted through the heat exchange channel in the return air member 6 and the air duct in the air duct assembly 5 to the area close to the opening of the storage compartment 3 in the storage compartment 3, and the cold can flow from the area close to the opening in the storage compartment 3 to the return air member 6, thereby improving the uniformity of the cold distribution in the storage compartment.

[0051] See Figures 9 to 14 , the adapter 53 further has a handle 532, the handle 532 is connected to the adapter portion 531, the housing 51 is further provided with a chute 512, and the handle 532 is located in the chute 512 and can move along the chute 512;

[0052] See Figures 9 to 10 , when the adapter 53 is in the first position, the handle 532 is located at the end of the chute 512 away from the mounting base 52; See Figures 11 to 12 , when the adapter 53 is in the second position, the handle 532 is located at the end of the chute 512 close to the mounting base 52.

[0053] In this way, by controlling the movement of the handle 532 in the chute 512, the movement of the adapter 53 between the first position and the second position can be realized.

[0054] Wherein, the part of the handle 532 connected to the adapter portion 531 is located inside the housing 51, so as to avoid interference between the adapter 53 and the mounting base 52 when the housing 51 is disassembled.

[0055] Preferably, at least part of the handle 532 extends out of the chute 512, so as to facilitate controlling the movement of the handle 532 in the chute 512.

[0056] See Figures 9 to 12 , the air duct assembly 5 further includes an elastic member 55, the elastic member 55 is arranged inside the housing 51, the mounting structures are arranged in pairs, the elastic member 55 connects a pair of the mounting structures, and when the adapters 53 of a pair of the mounting structures, that is, a pair of the adapters 53, are respectively in their second positions, the elastic member 55 has a first compression deformation amount x 1 .

[0057] In this way, when a pair of the mating members 53 are respectively located at their respective second positions, under the action of its own elastic restoring force, the elastic member 55 applies a thrust force to a pair of the mating members 53 respectively, so that the mating members 53 have a tendency to move towards the mating grooves 521 corresponding to them, that is, a tendency to move away from each other, so that the mating portions 531 can abut against the mating grooves 521, and further improve the mating strength between the mating portions 531 and the mounting base 52, so as to prevent the housing 51 from disengaging from the mounting base 52 during use, resulting in insecure installation and affecting the cooling capacity transmission effect.

[0058] In addition, the installation structure is provided in pairs. On the one hand, the assembly strength between the housing 51 and the mounting base 52 is improved. On the other hand, it is beneficial for the user to make a pair of the mating members 53 move towards each other, that is, move towards their respective first positions, when disassembling by simultaneously holding a pair of the mating members 53, which can save effort and is convenient for operation.

[0059] When a pair of the mating members 53 are respectively at their respective first positions, the elastic member 55 has a second compression deformation amount x 2 , the second compression deformation amount x 2 > the first compression deformation amount x 1 .

[0060] In this way, when installing the housing 51, after the housing 51 is placed at the preset position and the external force is removed, a pair of the mating members 53 can move from their respective first positions to the second positions under the action of the elastic restoring force of the elastic member 55 itself, achieving the effect of saving effort.

[0061] Refer to Figures 11 to 12 , in an embodiment, the elastic member 55 includes a spring 551 and a limiting member 552. The limiting member 552 connects a pair of the mating members 53, and the spring 551 is sleeved on the outer periphery of the limiting member 552. The spring 551 can provide a thrust force for the mating members 53 to make the mating members 53 move from the first position to the second position, and the limiting member 552 can limit and fix the spring 551 to prevent the spring 551 from falling off and losing its effect.

[0062] In other embodiments, the elastic member 55 can also adopt other elastic members such as rubber parts, as long as it can drive the mating members 53 to move from the first position to the second position under the action of its own elastic restoring force.

[0063] In a specific embodiment, the limiting member 552 includes a pair of limiting posts 5521 arranged at intervals, the pair of limiting posts 5521 are respectively arranged on a pair of the matching members 53, and the two ends of the spring 551 are respectively sleeved outside the pair of limiting posts 5521. In this way, the assembly and replacement of the elastic member 55 are facilitated to increase the service life of the air duct assembly 5.

[0064] Preferably, the limiting member 552 is connected to the matching portions 531 of a pair of the matching members 53, and specifically, the pair of limiting posts 5521 are respectively connected to the matching portions 531 of a pair of the matching members 53. In this way, the force of the elastic member 55 on the matching portions 531 can be increased, so as to prevent the matching member 53 from tilting and deviating from its preset motion trajectory during the movement from the first position to the second position, thereby preventing the matching portion 531 from being unable to pass through the matching hole 54 and be matched in the matching groove 521.

[0065] See also Figures 9 to 14 The housing 51 includes a top cover 513 and a pair of side panels 514 arranged opposite to each other, the top cover 513 is connected to the pair of side panels 514, the top cover 513 is located at one end of the housing 51 facing the opening, the matching hole 54 is provided on the side panel 514, and the slide slot 512 is provided on the top cover 513. This makes it easy to operate the handle 532 and also makes it easy to connect the mounting seat 52 with the inner container 11.

[0066] Among them, the matching holes 54 of each of the pair of mounting structures are correspondingly arranged on the pair of side panels 514, the mounting seats 52 of each of the pair of mounting structures are respectively arranged on the side of the pair of side panels 514 away from each other, and the slide grooves 512 of each of the pair of mounting structures are spaced apart on the top cover 513.

[0067] The mounting structure is disposed in a region of the housing 51 close to the inner container 11 .

[0068] The inner tank 11 includes a pair of side walls 111 arranged opposite to each other, the air return member 6 is arranged on the side walls 111, and the air duct assembly 5 is connected to the pair of side walls 111. Specifically, the inner tank connecting plate 523 of the mounting seat 52 is connected to the side walls 111.

[0069] Preferably, two pairs of the mounting structures are provided, and the two pairs of the mounting structures are respectively provided at opposite ends of the housing 51. That is, the two pairs of the mounting structures are respectively provided at opposite ends of the housing 51 close to the inner liner 11, so that the two ends of the housing 51 can be respectively connected to the inner liner 11, thereby improving the connection strength of the inner liner 11.

[0070] In summary, for the air duct assembly 5 of the present application and the refrigeration device 100 having the same, through the installation structure, the installation seat 52 can be assembled with the inner tank 11. In this way, when the mating part 53 is in the first position, the housing 51 can be disengaged from the installation seat 52, so that the housing 51 can be disassembled and replaced; when the mating part 53 is in the second position, the mating portion 531 passes through the mating hole 54 on the housing 51 and is mated with the mating groove 521 of the installation seat 52, thereby restricting the movement of the housing 51 relative to the installation seat 52. During installation, when the mating part 53 is in the first position, the housing 51 can be placed at a preset installation position, and then the mating part 53 is moved to the second position, so that the housing 51 and the installation seat 52 can be relatively fixed; when disassembling the housing 51, the mating part 53 is moved from the second position to the first position, and the housing 51 can be disassembled; in this way, the installation and fixation of the housing 51 and the non-destructive disassembly and replacement can be realized, and the operation is simple and convenient.
