Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0033] See also Figures 1 to 3 , an embodiment of the utility model provides an air duct assembly comprising:

[0034] The air duct front cover and the air duct rear cover cover each other and define a main air cavity 12, a first air cavity 13, a second air cavity 14, a main air supply duct 16, a first air supply duct and a second air supply duct. The first air cavity 13, the second air cavity 14 and the main air supply duct 16 are respectively connected to the main air cavity 12. A fan is arranged in the main air cavity 12 for supplying air to the first air cavity 13, the second air cavity 14 and the main air supply duct 16. The first air supply duct is connected to the first air cavity 13 and is located downstream of the first air cavity 13. The second air supply duct is connected to the second air cavity 14 and is located downstream of the second air cavity 14.

[0035] It can be understood that a fan is provided in the main air cavity 12, which is the source of cold air.

In order to efficiently utilize the cold air in the main air cavity 12, the main air cavity 12 can be directly located in the area with the highest cold air.

[0036] It can be understood that when the main air cavity 12 supplies air to the first air cavity 13 and the second air cavity 14, the main air cavity 12 can be directly connected with the first air cavity 13 and the second air cavity 14 to supply air, or the main air cavity 12 can indirectly supply air to the first air cavity 13 and the second air cavity 14 via other intermediate components. When the main air cavity 12 directly supplies air to the first air cavity 13 and the second air cavity 14, the air supply efficiency is the highest.

[0037] It can be understood that when the first air cavity 13 and the second air cavity 14 supply air to the first air supply duct and the second air supply duct, the first air cavity 13 and the second air cavity 14 can be directly connected with the first air supply duct and the second air supply duct respectively to supply air, or the first air cavity 13 and the second air cavity 14 can be indirectly connected to the first air supply duct and the second air supply duct through other intermediate components. When in use, considering the space problem during installation, it is not convenient to directly connect the first air cavity 13 and the second air cavity 14 with the first air supply duct and the second air supply duct, and an intermediate component can be used as a connection.

[0038] In one embodiment, the main air supply duct 16 includes a plurality of sub-air supply ducts arranged around the main air cavity 12 , and a main air outlet 17 is provided on a side of each sub-air supply duct away from the main air cavity 12 .

[0039] It can be understood that the shape of the main air cavity 12 can be set to be circular, the sub-air supply ducts can be evenly arranged around the main air cavity 12, and 4 sub-air supply ducts can be set, which can make the air delivered by the sub-air supply ducts more uniform and have a better cooling effect.

[0040] In one embodiment, the first air cavity 13 is disposed adjacent to the main air cavity 12; and / or

[0041] The second air cavity 14 is disposed on a side of the first air cavity 13 away from the main air cavity 12 .

[0042] It can be understood that the first air cavity 13 is arranged adjacent to the main air cavity 12, that is, the cold air of the main air cavity 12 can be directly sent to the first air cavity 13, and the air of the first air cavity 13 can be sent to a relatively weaker area in need of cold air when in use. The second air cavity 14 is arranged on a side of the first air cavity 13 away from the main air cavity 12, that is, the second air cavity 14 is relatively farther from the main air cavity 12 than the first air cavity 13, and the air of the second air cavity 14 can be sent to a relatively weaker area in need of cold air when in use.

[0043] In one embodiment, the duct front cover includes a first duct front cover 10 and a second duct front cover 30, and the duct rear cover includes a first duct rear cover 11 and a second duct rear cover 31, the first duct front cover 10 and the first duct rear cover 11 cover each other and define the main air cavity 12, the first air cavity 13, the second air cavity 14, and the main air supply duct 16, the second duct front cover 30 is connected to the first duct front cover 10, the second duct rear cover 31 is connected to the first duct rear cover 11, and the second duct front cover 30 and the second duct rear cover 31 cover each other and define the first air supply duct and the second air supply duct.

[0044] It can be understood that when installing the air duct front cover and the air duct rear cover, it is necessary to consider the coordination with each air-requiring area. Splitting the air duct front cover and the air duct rear cover into different parts can be more convenient for operation during installation and production. At the same time, since the first air duct front cover 10 and the first air duct rear cover 11 define the main air cavity 12, the first air cavity 13, the second air cavity 14 and the main air supply duct 16, and the fan is arranged in the main air cavity 12, the space required is relatively large. Splitting the air duct front cover and the air duct rear cover into different parts can also fully consider the space size of different parts, thereby better saving space. The first air duct front cover 10 and the first air duct rear cover 11, the second air duct front cover 30 and the second air duct rear cover 31 can be arranged as one piece or separately. The one-piece arrangement is convenient for installation and has better sealing.

The temperature-changing room and the refrigerating room are generally arranged above the freezer compartment, and the second air duct front cover 30 and the second air duct rear cover 31 can be arranged above the first air duct front cover 10 and the first air duct rear cover 11 accordingly.

[0048] The first air duct front cover 10 of the air duct front cover and the first air duct rear cover 11 of the air duct rear cover are disposed in the freezing chamber shell 20 .

[0049] It is understandable that the first air duct rear cover 11 can be provided integrally with the freezing chamber housing 20 or can be provided separately. The shapes of the first air duct front cover 10 and the first air duct rear cover 11 match the freezing chamber housing 20.

[0050] In one embodiment, a through hole 15 is disposed on the first air duct rear cover 11 , and the fan is disposed on the freezing chamber shell 20 via the through hole 15 .

Separate arrangement can facilitate the separate arrangement of the third air cavity. The second air outlet 22 can be set at the top of the freezing chamber shell 20, so that the first air cavity 13 and the second air cavity 14 can supply air to the first air supply duct and the second air supply duct above.

[0054] In one embodiment, the freezer chamber shell 20 and the temperature changing chamber shell are stacked in the outer shell, a third air supply duct is defined between the freezer chamber shell 20, the temperature changing chamber shell and the outer shell, the first air outlet 21 is connected to the temperature changing chamber via the third air supply duct, and a solenoid valve is arranged in the third air supply duct.
