[0020] FIG. 1 illustrates a schematic structural diagram of an air duct assembly according to an embodiment of the present invention and FIG. 10 illustrates a schematic exploded structural diagram of an air duct member according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 10, the air duct assembly includes an air duct member 20, an air supply pipe member 60 and an air return pipe member 70. The air duct member 20 is provided inside a compartment of a cabinet liner body 10, an interior of the air duct member 20 is provided with an accommodation cavity 25, an evaporator member 40 is provided inside the accommodation cavity 25 and the air duct member 20 is provided with a first air return port 57 and a first air supply port (not shown) communicating with the accommodation cavity 25. The air supply pipe member 60 communicates with the first air supply port; and the air return pipe member 70 communicates with the first air return port 57.

[0021] According to the air duct assembly of the embodiment of the present invention, an invalid space inside the air duct member 20 is effectively utilized, and a volume ratio of the refrigeration apparatus is improved by providing the evaporator member 40 inside the air duct member 20. An air duct system consisting of the air duct member 20 and the air supply pipe member 60 shortens an air circulation path to the maximum extent and improves the refrigeration efficiency. During a final assembly stage, the air duct member 20 only needs to be provided inside the compartment of the cabinet liner body 10, without mounting the evaporator separately, which simplifies the mount steps of the air duct member 20 and improves production efficiency.

[0022] It may be understood that, as shown in FIG. 7, a side of the cabinet liner body 10 is provided with a first opening communicating with the compartment, the first air return port 57 is provided at a side of a top of the air duct member 20 close to the first opening, and the first air supply port is provided at a side of the top of the air duct member 20 away from the first opening. The first opening is an article removal port of the refrigeration apparatus, and the first opening is located at a side of the refrigeration apparatus close to a door body.

[0023] It may be understood that FIG. 2 illustrates a schematic structural diagram of an air supply pipe member and an air return pipe member according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, both the air supply pipe member 60 and the air return pipe 70 are located outside a top of the cabinet liner body 10. By providing both the air supply pipe member 60 and the air return pipe 70 outside the top of the cabinet liner body 10, a distance between the air supply pipe member 60, the air return pipe 70 and a refrigerator compartment is decreased to shorten the circulation path of the air duct system, and improve the refrigeration efficiency.

[0024] The top of the cabinet liner body 10 is provided with a plurality of through holes. The air supply pipe member 60 is provided at a side of the top of the air duct member 20 away from the first opening and the air supply pipe member 60 penetrates through a corresponding through hole to communicate with a corresponding compartment and the first air supply port. The air return pipe member 70 is provided at a side of the top of the air duct member 20 close to the first opening and the air return pipe member 70 penetrates through a corresponding through hole to communicate with a corresponding compartment and the first air return port 57. A foaming material may completely isolate the air supply pipe member 60 from the air return pipe member 70 to avoid the risk of frost caused by alternating hot and cold during the foaming process since the air supply pipe member 60 and air return pipe member 70 are two independently provided members.

[0025] It may be understood that, as shown in FIG. 1 and FIG. 2, a position pin is provided at a side of the air supply pipe member 60 close to the air return pipe member 70, and a position hole 53 is provided at a side of the air return pipe member 70 close to the air supply pipe member 60. The position pin is inserted into the corresponding position hole 53 to achieve the connection between the air supply pipe member 60 and air return pipe member 70. The air supply pipe member 60 and the air return pipe member 70 may be assembled offline and then assembled with the air duct member 20, or they may be assembled separately and independently with the air duct member 20.

[0026] It may be understood that a cabinet liner assembly includes two cabinet liner bodies 10 distributed upward and downward, a compartment is provided inside each cabinet liner body 10, two compartments are distributed upward and downward, and the air duct member 20 is provided inside the compartment of a lower cabinet liner body 10. An upper compartment is a refrigerator compartment, and the refrigerator compartment and a lower compartment are two independent compartments. The air duct member 20 divides the lower compartment into a freezer compartment and a variable temperature compartment. In order to meet the different needs of users, a chill compartment may also be set in the refrigerator compartment.

[0027] It may be understood that FIG. 3 illustrates a schematic structural diagram in bottom view of an air return pipe member according to an embodiment of the present invention and FIG. 4 illustrates a schematic exploded structural diagram of an air return pipe member according to an embodiment of the present invention. As shown in FIG. 3 and FIG. 4, the air return pipe member 70 includes an air return pipe, and an upper part of the air return pipe is provided with a first refrigerator air return port 71, and the first refrigerator air return port 71 is suitable for communicating with an air return port of the upper refrigerator compartment. A lower part of the air return pipe is provided with a first variable temperature air return port 72, a second variable temperature air return port 73 and a second refrigerator air return port 74. The first refrigerator air return port 71 communicates with the second refrigerator air return port 74, and the first variable temperature air return port 72 communicates with the second variable temperature air return port 73; and both the first variable temperature air return port 72 and the second refrigerator air return port 74 communicate with the first air return port 57. The second variable temperature air return port 73 is suitable for communicating with a variable temperature compartment. The integrated design simplifies the structure of the air return pipe, reduces the production cost, and improves the reliability of the air return pipe since the refrigerator compartment and the variable temperature compartment share an air return pipe. The air return pipe member 70 is located in a foaming layer between the lower compartment and the upper compartment. The distance between the air return pipe member 70 and the refrigerator compartment or a variable temperature compartment is the shortest, which effectively decreases a length of the air return pipe path.

[0028] It may also be understood that a plurality of air guide sheets are provided at intervals at the second variable temperature air return port 73 and inclined toward the first variable temperature air return port 72. Air in the variable temperature compartment directly flows to the first variable temperature air return port 72 under the action of the air guide sheets after entering the second variable temperature air return port 73, which reduces an air flow path and wind resistance to further improve the refrigeration efficiency.

[0029] It may be understood that, as shown in FIG. 3 and FIG. 4, the air return pipe includes an air return pipe upper housing 75 and an air return pipe lower housing 76. The first refrigerator air return port 71 is provided at the upper part of the air return pipe upper housing 75, and is a rectangular air port. The first variable temperature air return port 72 and the second refrigerator air return port 74 are provided at the lower part of the air return pipe upper housing 75, and both the first variable temperature air return port 72 and the second refrigerator air return port 74 are rectangular air ports, and the first variable temperature air return port 72 is suitable for conveying the air in the variable temperature compartment to the first air return port 57. The air inside the refrigerator compartment first enters the first refrigerator air return port 71, and then is conveyed to the first air return port 57 through the second refrigerator air return port 74. The air inside the refrigerator compartment and the air inside the variable temperature compartment finally enter the accommodation cavity 25 through the first air return port 57 to exchange heat with the evaporator member.

[0030] The air return pipe lower housing 76 is provided below the air return pipe upper housing 75, and the second variable temperature air return port 73 is provided at the lower part of the air return pipe lower housing 76, and the second variable temperature air return port 73 is located above the variable temperature compartment. The air return pipe lower housing 76 and the air return pipe upper housing 75 enclose a second flow passage, and the second flow passage communicates with the first variable temperature air return port 72 and the second variable temperature air return port 73 respectively. A communication method of the first variable temperature air return port 72 and the second variable temperature air return port 73 is not limited to this, and the first variable temperature air return port 72 may also communicate directly with the second variable temperature air return port 73. The air return pipe lower housing 76 is connected to the lower part of the air return pipe upper housing 75 by a buckle to facilitate the mounting and disassemble of the air return pipe. A connection method of the air return pipe lower housing 76 and the air return pipe upper housing 75 is not limited to this, and a bolt or an integrally formed connection method may also be used.

[0031] It may be understood that FIG. 13 illustrates a schematic structural diagram in front view of a cabinet liner body according to an embodiment of the present invention; FIG. 14 is a schematic cross-sectional structural diagram of a section line A-A in FIG. 13; FIG. 15 is a schematic cross-sectional structural diagram of a section line C-C in FIG. 13; and FIG. 16 is a schematic cross-sectional structural diagram of a section line B-B in FIG. 13. As shown in FIG. 13 to FIG. 16, the air supply pipe member 60 communicates with a freezer compartment air supply port 68, a refrigerator compartment air supply port, a chill compartment air supply port, and a variable temperature compartment air supply port 69 respectively. Such an integrated design simplifies the structure of an air supply pipeline and reduces the production cost since pipelines for conveying cold air to each compartment are integrated into the air supply duct.

[0032] It may be understood that FIG. 5 illustrates a schematic structural diagram of an air supply pipe member according to an embodiment of the present invention and FIG. 6 illustrates a schematic exploded structural diagram of an air supply pipe member according to an embodiment of the present invention. As shown in FIG. 5 and FIG. 6, the air supply pipe member 60 includes an air supply pipe, a first air damper 64 and a second air damper 65. An interior of the air supply pipe is provided with a first flow passage, and the air supply pipe is provided with an air inlet, a second air supply port 61, a third air supply port 62 and a fourth air supply port communicating with the first flow passage, where the air inlet communicates with the first air supply port, and temperature-reduced cold air enters the first flow passage through the first air supply port and the air inlet in turn, and then the cold air is conveyed into a corresponding compartment through the second air supply port 61, the third air supply port 62 and the fourth air supply port. The first air damper 64 is provided at the second air supply port 61, and an air inlet port of the first air damper 64 communicates with the second air supply port 61. The second air damper 65 is provided at the third air supply port 62, and an air inlet port of the second air damper 65 communicates with the third air supply port 62.

[0033] The first air damper 64 is a double air damper, a first air outlet port of the first air damper 64 communicates with an air outlet of the refrigerator compartment, the second air outlet port of the first air damper 64 communicates with an air supply port of the chill compartment, and the first air damper 64 is suitable for controlling cooling capacity entering the refrigerator compartment and the chill compartment respectively. The second air damper 65 is a single air damper, and an air outlet of the second air damper 65 communicates with the variable temperature compartment air supply port 69. The second air damper 65 is suitable for controlling cooling capability entering the variable temperature compartment. The fourth air supply port communicates with the freezer compartment air supply port 68. The type of the first air damper 64 is not limited thereto, and it may also be a single air damper or a triple air damper, which is specifically determined according to the temperature zone setting requirements of the refrigerator compartment.

[0034] It may be understood that the air supply pipe includes a first air supply pipe housing 66 and a second air supply pipe housing 67. The first air supply pipe housing 66 and the second air supply pipe housing 67 enclose the first flow passage, and the first air supply pipe housing 66 is connected to the second air supply pipe housing 67 by a buckle to facilitate the mounting and disassemble of the air supply pipe. The second air supply port 61 is formed by splicing an opening of the first air supply pipe housing 66 and an opening of the second air supply pipe housing 67. The second air supply port 61 may also be separately provided at the first air supply pipe housing 66 or the second air supply pipe housing 67. Similarly, the air inlet, the third air supply port 62 and the fourth air supply port may be spliced by an opening of the first air supply pipe housing 66 and an opening of the second air supply pipe housing 67, or the first air supply pipe housing 66 or the second air supply pipe housing 67 may be separately provided.

[0035] A working principle of the air duct assembly is as follows.

[0036] As shown in FIG. 1 to FIG. 6, during the air circulation process, air inside the refrigerator compartment first enters the first refrigerator air return port 71, and then enters the first air return port 57 through the second refrigerator air return port 74. Air inside the variable temperature compartment enters the first air return port 57 through the second variable temperature air return port 73 and the first variable temperature air return port 72 in turn. The air inside the refrigerator compartment and the air in the variable temperature compartment finally enter the accommodation cavity 25 through the first air return port 57 to exchange heat with the evaporator member. After the heat exchange, the temperature of the air is further reduced and the air becomes cold air. As shown in FIG. 5, the cold air (shown in filled wide arrow) enters the first flow passage through the first air supply port under the action of the fan 31. At this time, the cold air is divided into four paths in which a first path of cold air (shown in hollow wide arrow in a dashed line) enters the freezer compartment through the fourth air supply port for cooling; the second path of cold air (shown in narrow arrow in a dotted line) enters the first air damper 64, and finally enters the refrigerator compartment through the first air outlet port of the first air damper 64 for cooling; a third path of cold air (shown in narrow arrow in a solid line) enters the first air damper 64, and finally enters the chill compartment through the second air outlet port of the first air damper 64 for cooling; and a fourth path of cold air (shown in hollow wide arrow in a solid line) enters the second air damper 65 and finally enters the variable temperature compartment for cooling.

[0037] FIG. 7 illustrates a schematic diagram showing an assemble relationship between a cabinet liner body and an air duct member according to an embodiment of the present invention. As shown in FIG. 7 and FIG. 10, in the air duct member 20 according to the embodiment of the present invention, by providing the evaporator member 40 inside the air duct member 20, in the final assembly stage, it is only necessary to provide the air duct member 20 inside the compartment of the cabinet liner body 10, and then weld a pipeline of the evaporator member 40 with a pipeline of the refrigeration system, without providing a position for the evaporator mounting step separately, which reduces the labor cost, simplifies the mounting step of the air duct member, and improves the production efficiency.

[0038] It may be understood that the air duct member 20 is provided inside the compartment inside the cabinet liner body 10, and the air duct member 20 divides the compartment into a first compartment 14 and a second compartment 15. The air duct member 20 includes at least two detachably connected cover plates, an accommodation cavity 25 is formed inside the air duct member 20 and the evaporator member 40 is provided inside the accommodation cavity 25.

[0039] According to the air duct member 20 of the embodiment of the present invention, only the cover plate needs to be removed to disassemble the evaporator member 40 when the evaporator member 40 is disassembled by providing the evaporator member 40 inside the accommodation cavity 25, which simplifies the disassembly steps of the evaporator member 40 and facilitates the maintenance of the evaporator member 40.

[0040] It may be understood that the air duct member 20 is provided inside the compartment of the cabinet liner body 10, an adhesive accommodation groove 26 is provided at a side of the air duct member 20 facing an inner wall of the cabinet liner body 10, and the inner wall of the cabinet liner body 10 is provided with a through hole 16 communicating with the adhesive accommodation groove 26, and the adhesive accommodation groove 26 is filled with a foaming material connected to the inner wall and the side of the air duct member 20 respectively.

[0041] It may be understood that, as shown in FIG. 10, the air duct member 20 includes a first cover plate 21, a second cover plate 22, a vacuum heat-insulation panel 23 and a vacuum heat-insulation panel cover plate 24. The second cover plate 22 is provided opposite to the first cover plate 21, and the vacuum heat-insulation panel 23 is provided between the second cover plate 22 and the first cover plate 21. The vacuum heat-insulation panel cover plate 24 is provided at a side of the vacuum heat-insulation panel 23 away from the second cover 22. The vacuum heat-insulation panel cover plate 24 has a shape matching the shape of the first cover plate 21 and the shape of the second cover plate 22. Both an area of the vacuum heat-insulation panel cover plate 24 and an area of the second cover plate 22 are larger than an area of the vacuum heat-insulation panel 23 to ensure that the vacuum heat-insulation panel 23 may be completely wrapped when the vacuum heat-insulation panel 23 is sandwiched between the vacuum heat-insulation panel cover plate 24 and the second cover plate 22. The accommodation cavity 25 is formed between the vacuum heat-insulation panel cover plate 24 and the first cover plate 21, that is, the accommodation cavity 25 is enclosed by the vacuum heat-insulation panel cover plate 24 and the first cover plate 21, and the accommodation cavity 25 is used to mount a fan member, the evaporator member 40 and the fan mount cover plate 33. The vacuum heat-insulation panel cover plate 24 is connected to the first cover plate 21 and the second cover plate 22 respectively by screws, and may also be connected by buckles, or by other detachable connection methods. The adhesive accommodation groove 26 is formed on a rear side 27 and a lower side 28 of the vacuum heat-insulation panel cover plate 24, and the position of the adhesive accommodation groove 26 corresponds to the position of the position groove 13. The first air return port 57 and the first air supply port are provided at the top of the vacuum heat-insulation panel cover plate 24.

[0042] In the related art, the evaporator member 40 is located at a rear side of the freezer air duct assembly. When the evaporator member 40 is disassembled, it is necessary to first remove the freezer drawers on both sides, then remove screws of a middle partition plate in a freezer cabinet liner, then remove the middle partition plate, then remove the screws of the freezer air duct assembly, then remove the freezer air duct assembly, and finally remove the evaporator member. It is largely difficult to maintain the evaporator since disassembly steps of the evaporator are cumbersome.

[0043] Not only the mounting steps of the refrigeration apparatus are simplified, but also the disassembly steps of the evaporator member 40 are simplified by providing the evaporator member 40 inside the accommodation cavity 25. When the evaporator member 40 is disassembled, the freezer drawer at a side of the freezer air duct is first removed, the screws of the first cover plate 21 or the second cover plate 22 are then removed, the first cover plate 21 or the second cover plate 22 is then removed, and the evaporator member 40 is finally removed. Compared with the disassembly method of the evaporator in the above-mentioned related art, the evaporator member 40 is provided inside the accommodation cavity 25, which not only increases the capacity of the refrigeration apparatus, simplifies the mount steps of the refrigeration apparatus, but also simplifies the mount steps of the evaporator member 40.

[0044] It may be understood that the air duct member 20 is vertically provided inside the compartment, the first cover plate 21 is located at a side of the air duct member 20 facing the first compartment 14, and the second cover plate 22 is located at a side of the air duct member 20 away from the first compartment 14.
