The upper end of the blowing foam 400 can abut against the lower side wall of the refrigerating chamber 200, and the lower end of the blowing foam 400 can abut against the upper side wall of the freezing chamber 300. A connecting air duct 410 is defined in the blowing foam 400 to communicate with the refrigerating communication port 211 and the freezing communication port.

[0047] Refer to Figure 5 and Figures 8 to 10 Figures 8 to 10 , in this embodiment, on the end wall of the blowing foam 400 facing the refrigerating chamber 200, an installation groove 413 may be recessed at the position of the connecting air duct 410. The installation groove 413 extends towards the refrigerating chamber 200 to penetrate through one end of the connecting air duct 410 facing the refrigerating chamber 200, so as to facilitate the installation and disassembly of the air door assembly 500. The inner peripheral wall of the installation groove 413 can be in sealing abutment with the air door assembly 500, thereby ensuring the sealing performance between the blowing foam 400 and the air door assembly 500.

[0048] In some embodiments, a sealing groove 414 may be recessed in the inner peripheral wall of the installation groove 413.

A second air duct portion 412 is defined in the second foam 422, and the second air duct portion 412 can communicate with the first air duct portion 411 to form the connecting air duct 410 in combination.

[0050] The air door assembly 500 may be disposed on the side of the first foam 421 facing the refrigerating chamber 200. The first foam 421 itself may be injection molded, and its overall structural strength is high, so as to prevent the air door assembly 500 from spreading the first foam 421 during installation, thereby reducing the leakage of materials and cold.

[0051] In some embodiments, an angle may be provided between the axis of the first air duct portion 411 and the axis of the second air duct portion 412, so that an arc transition is formed between the first air duct portion 411 and the second air duct portion 412. The air supply foam 400 is divided into a first foam 421 and a second foam 422, which facilitates the demolding of the first foam 421 and the second foam 422 during the injection molding of the air supply foam 400, improves the production efficiency of the air supply foam 400, and ensures the molding quality of the air supply foam 400.

[0052] In some other embodiments, a first air duct portion 411 is formed in the first foam 421.

[0066] The damper 560 may be provided with a flexible sealing plate 561, which can abut against the sealing ridge 540 to seal the damper vent 511. When the damper 560 is covered on the sealing ridge 540, the flexible sealing plate 561 can be recessed to fit the sealing ridge 540, thereby improving the airtightness between the damper 560 and the sealing ridge 540.

[0067] In some embodiments, the flexible sealing plate 561 may be a sponge plate. In other embodiments, the flexible sealing plate 561 may also be a rubber plate or a silicone plate.

[0068] In some embodiments, in the direction away from the cold storage chamber 200, the cross-sectional area of ​​the sealing flange 540 gradually decreases from top to bottom to reduce the elastic force exerted by the flexible sealing plate 561 on the sealing flange 540, thereby facilitating the sealing flange 540 to abut against the flexible sealing plate 561, increasing the size of the sealing flange 540 sunk into the flexible sealing plate 561, and improving the airtightness between the sealing flange 540 and the damper 560.

[0069] See also Figures 8 to 12 In this embodiment, the damper assembly 500 may further include a limiting flange 550.

[0073] In other embodiments, a motor mounting housing 571 may be provided on the damper mounting plate 510. A motor mounting cavity is formed in the motor mounting housing 571 for accommodating the driving motor. The motor mounting housing 571 is located on one side of the damper mounting plate 510 in the circumferential direction. The mounting flange 520 extends along the circumferential direction of the damper mounting plate 510, and both ends of the mounting flange 520 can be connected to the motor mounting housing 571, so that the mounting flange 520 and the motor mounting housing 571 enclose a cuboid structure.

[0074] One end of the motor mounting housing 571 away from the refrigerating chamber 200 can abut against the bottom wall of the mounting groove 413, and the circumferential side wall of the motor mounting housing 571 can abut against the inner circumferential wall of the mounting groove 413, so as to increase the contact area between the damper assembly 500 and the inner wall of the mounting groove 413 and improve the connection strength between the damper assembly 500 and the blowing foam 400.

[0077] In some embodiments, the first seal 530 can also be wrapped around the outer side wall of the motor mounting housing 571 to improve the sealing performance between the motor mounting housing 571 and the inner wall of the mounting groove 413.

[0078] Refer to Figures 1 to 3 、 Figure 6 and Figure 7 , in the present embodiment, the refrigerator may further include a refrigerating air duct cover plate 220. The refrigerating air duct cover plate 220 is detachably covered in the refrigerating chamber 200. A refrigerating air duct 221 may be provided in the refrigerating air duct cover plate 220. The refrigerating air duct 221 can be connected to the connecting air duct 410 through a refrigerating communication port 211. The damper assembly 500 can open and close the connecting air duct 410 to control whether the air in the freezing chamber 300 is input into the refrigerating chamber 200.

[0079] On one side of the refrigerating air duct cover plate 220 facing the air supply foam 400, there may be a protruding abutting block 222 provided. The abutting block 222 may be provided on the peripheral side of the refrigerating air duct 221. The abutting block 222 can abut against one side of the air door assembly 500 facing the refrigerating chamber 200, so as to press the air door assembly into the installation groove 413, prevent the air door assembly 500 from jumping out of the installation groove 413 during the transportation of the refrigerator, and improve the structural strength of the refrigerator.

[0080] In some embodiments, the abutting block 222 may be annularly provided on the outer periphery of the refrigerating air duct 221. The inner peripheral wall of the abutting block 222 can abut against the outer peripheral wall of the limiting convex edge 550. On the one hand, it can improve the limiting strength between the refrigerating air duct cover plate 220 and the air door assembly 500. On the other hand, it is convenient to guide the air flow in the connecting air duct 410 to be input into the refrigerating air duct 221, and improve the flow efficiency of the cold air.

[0081] In some embodiments, the refrigerating air duct cover plate 220 is detachably installed on the rear side wall of the refrigerating chamber 200. The lower end of the refrigerating air duct cover plate 220 can be pressed and attached to the lower side wall of the refrigerating chamber 200 to ensure the sealing performance between the refrigerating air duct cover plate 220 and the lower side wall of the refrigerating chamber 200.

[0082] In other embodiments, a second sealing member 230 may be provided in the refrigerating chamber 200. The second sealing member 230 may be provided around the periphery of the refrigerating communication port 211. The second sealing member 230 can abut against the lower part of the refrigerating air duct cover plate 220 to seal the gap between the refrigerating air duct cover plate 220 and the refrigerating chamber 200, and ensure the sealing performance between the refrigerating air duct cover plate 220 and the lower side wall of the refrigerating chamber 200.

[0083] Refer to Figures 1 to 12 , in the present utility model, during the assembly process of the refrigerator, the foaming layer is foamed and formed to press and limit the air supply foam 400 between the refrigerating chamber 200 and the freezing chamber 300. Then, the air door assembly 500 is put into the installation groove 413 through the refrigerating communication port 211, so that the installation convex edge 520 is accommodated and limited in the installation groove 413, and the first sealing member 530 is accommodated and limited in the sealing groove 414, thereby simplifying the installation steps of the air door assembly 500 and improving the installation efficiency of the air door assembly 500. After that, the refrigerating air duct cover plate 220 is installed in the refrigerating chamber 200, so that the refrigerating air duct cover plate 220 presses on the air door mounting plate 510, thereby preventing the air door assembly 500 from jumping and ensuring the structural stability of the refrigerator.

[0084] After the air supply foam 400 is limited in the air supply foam 400, the user can control the rotation of the air door 560, thereby regulating the on-off of the connecting air duct 410 to control whether the cold air in the freezing chamber 300 flows into the refrigerating chamber 200.

[0085] When the air door assembly 500 is damaged, by removing the refrigerating air duct cover plate 220 and then moving the air door assembly 500 from the installation groove 413 to the refrigerating chamber 200 through the refrigerating communication port 211, the air door assembly 500 can be disassembled quickly and simply, improving the disassembly efficiency, maintenance efficiency and replacement efficiency of the air door assembly 500.

[0086] After the air door assembly 500 is repaired or replaced, the air door assembly 500 is then moved into the installation groove 413 through the refrigerating communication port 211, so as to install the air door assembly 500 in the air supply foam 400. The air door assembly 500 is quickly installed in the air supply foam 400, thus facilitating the disassembly and maintenance of the air door assembly 500. Moreover, the air door assembly 500 is installed in the air supply foam 400 through the refrigerating communication port 211, without the need to disassemble the air supply foam 400 and the refrigerating air duct cover plate 220, effectively preventing air leakage and cold gaps from occurring during the disassembly and assembly processes of the air supply foam 400 and the refrigerating air duct cover plate 220, and ensuring the overall air supply quality of the refrigerator.
