An air-cooled refrigerator comprises a bottom liner, a fan bottom shell, an air duct cover plate, and fan blades. A cooling chamber and a storage space are defined in the bottom liner. The fan bottom shell is arranged at a rear portion of the cooling chamber. The air duct cover plate comprises a back plate portion and a fan upper cover. The back plate portion is disposed in front of a rear wall of the bottom liner. The fan upper cover obliquely extends downward from a lower end of the back plate portion into the cooling chamber, covers the fan bottom shell and is fastened thereto. The back plate portion and the fan upper cover are integrally formed. The fan blades are arranged in a fan cavity, and enable formation of a refrigeration airflow discharged from the cooling chamber to an air supply duct.

Air-cooled refrigerator

Provided is an air-cooled refrigerator with an evaporator at the bottom of a cabinet thereof. The air-cooled refrigerator includes: a cabinet with a bottom liner; a partition cover plate transversely arranged in the bottom liner to divide the bottom liner into a storage space and a cooling chamber below the storage space; a return air cover arranged at the front of the cooling chamber and provided with at least one front return air inlet; and an evaporator, which is in a flat cuboid shape and is mounted in the cooling chamber in a manner of inclining upwards from front to back, where a front portion of a top surface of the evaporator, the partition cover plate and the return air cover define a frost-accommodating space, such that some of the air that enters from the front return air inlet enters the evaporator from the frost-accommodating space.
