[0034] In this embodiment, the first air port 111 is a return air port and the second air port 112 is an outlet. When the fan assembly 30 is working, the air in the inner liner 10 is extracted so that the air in the inner liner 10 enters the air duct assembly 20 through the first air port 111, i.e., the return air port, flows to the air duct assembly 20, and flows back to the inner liner 10 from the second air port 112, i.e., the outlet, to accelerate the circulation of air in the inner liner 10. The fan assembly 30 and the air duct assembly 20 are arranged on the same side of the inner liner 10, reducing the space occupied by the air duct assembly 20 or the fan assembly 30 on other surfaces of the inner liner 10.

[0035] Optionally, when the first air outlet 111 is an air outlet and the second air outlet 112 is an air return outlet, the fan assembly 30 can be arranged in the second air outlet 112. In this embodiment, the fan assembly 30 can be arranged in at least one of the first air outlet 111 and the second air outlet 112 according to the setting requirements and usage scenarios.

[0036] According to the refrigerator 100 of the embodiment of the utility model, the air duct assembly 20 and the fan assembly 30 are arranged on the same side of the inner tank 10, which can reduce the occupation of the air duct assembly 20 and the fan assembly 30 on the outer space of the inner tank 10. At the same time, the arrangement of the air duct assembly 20 and the fan assembly 30 can accelerate the circulation of air in the inner tank 10, so that the temperature inside the refrigerator 100 is more uniform, the performance of the refrigerator 100 is improved, and it is conducive to the miniaturized design of the refrigerator 100.

[0037] In some embodiments, Figure 1 As shown, the air duct assembly 20 is arranged at the side or top of the inner liner 10.
