The second evaporator pan 420 includes a transverse plate body and a vertical plate body that enclose the side walls and steps of the liner to define the second evaporator pan 400. The structure of the second evaporator bin 400 can be simplified by adopting the arrangement form, so that the cost of the refrigerator can be reduced. The second evaporator cover 420 is provided with a second air return opening, and specifically, the second air return opening is provided with a vertically arranged cover plate of the second evaporator cover 420. On the one hand, the second air return opening is not easy to be blocked by the refrigerated object; on the other hand, the second air return opening formed in the second evaporator cover 420 can improve the air circulation effect near the second evaporator bin 400, and further improve the temperature uniformity of the refrigerating space.

Optionally, the bottom plate of the liner is configured with a plurality of grooves 251 and a plurality of ribs 252 that are arranged at intervals, and the bottom of the second evaporator cover 420 abuts against the upper surfaces of the plurality of ribs 252 so that the storage space is communicated with the second evaporator bin 400 through the plurality of grooves 251.

The bottom plate of the liner is constructed with a plurality of grooves 251 and a plurality of ribs 252, i.e., corrugated. The length direction of the plurality of grooves 251 and the plurality of ribs 252 is along the length direction of the refrigerator. This can improve the structural strength of the bottom plate 250 of the liner.

The bottom ends of the vertical plate bodies of the second evaporator cover 420 are abutted against the upper surfaces of the plurality of ribs 252, so that the refrigerating space is communicated with the second evaporator bin 400 through the plurality of grooves 251. This forms a plurality of return air channels in the bottom of the second evaporator bin 400. The refrigerator includes a first fan 330 and a second fan 430, the first fan 330 being disposed in the first evaporator bin 300, and the second fan 430 being disposed in the second evaporator bin 400. When the second fan 430 drives air to flow to the refrigerating space through the second air supply duct, due to the existence of air inertia, the air output of the second air supply duct close to the air outlet of the second evaporator bin 400 is smaller, the air output of the air outlet in the middle is larger, and then the air output to the far end is gradually reduced. Therefore, the circulation effect of the air is poor at a position close to the second evaporator bin 400. Similarly, the air circulation effect is poor in the vicinity of the first evaporator bin 300. Thus, a plurality of return air passages are formed through the bottom plate 250 of the liner to return air to the second evaporator bin 400 through the plurality of grooves 251 of the bottom plate 250 of the liner. This may enhance the circulation effect of the air in the vicinity of the first and second evaporator pans 300 and 400.
