Abstract
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.
