摘要： A refrigerator includes a lowermost storage liner, an evaporator, an air supply duct, and at least one air supply fan. A storage compartment and a cooling chamber positioned under the storage compartment are defined in the storage liner. The evaporator is disposed in the cooling chamber and is configured to cool air passing through the evaporator so as to form cooling air supplied to the storage compartment. The air supply duct is disposed in a space defined by the storage liner and is configured to convey the cooling air cooled by the evaporator to the storage compartment. The air supply fan is disposed in the air supply duct and is configured to promote air circulation between the cooling chamber and the storage compartment.

摘要： A refrigerator includes a top cover which separates a storage liner on a bottommost portion into a storage space located on an upper portion and a cooling space located on a lower portion. At least one return air hood is arranged at a front end of the top cover, the cooling space is jointly defined by the return air hood, the top cover and a bottom wall of the storage liner, and an evaporator is arranged in the cooling space. The return air hood includes a return air frame located on a front side and a return air rear cover inserted into the return air frame from an open rear end of the return air frame. The return air rear cover is arranged to separate a first opening formed in a front wall face of the return air frame into a first front return air inlet located on an upper portion and a second front return air inlet located on a lower portion, so that the visual attractiveness is achieved, and the fingers of children or foreign matter can be effectively prevented from entering the cooling space. In addition, due to two return air areas distributed vertically, return air can flow through the evaporator more evenly after entering the cooling space, the problem that a front end face of the evaporator is prone to frosting can be avoided to a certain degree, the heat exchange efficiency can be improved, the defrosting period can be prolonged, and energy conservation and high efficiency are achieved.

At least one first return air inlet communicated with the cooling chamber (150) is formed in a left sidewall of the first storage compartment such that a return airflow of the first storage compartment enters the cooling chamber (150) to be cooled via the first return air inlet. At least one second return air inlet communicated with the cooling chamber (150) is formed in a right sidewall of the second storage compartment such that a return airflow of the second storage compartment enters the cooling chamber (150) to be cooled via the second return air inlet. The available compartment volume of the refrigerator is increased, and the return air inlets communicated with the cooling chamber (150) are formed in left and right sidewalls of the cabinet respectively.
