Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Fig. 1 and 2 show a preferred embodiment of an air-cooled refrigerator according to the present invention, as shown in the figure, the air-cooled refrigerator includes a box body, the box body includes a box liner 1, a refrigeration compartment (preferably, the refrigeration compartment is a refrigerating compartment, and one or more refrigeration compartments are communicated with an air duct) is provided in the box liner 1; an air duct 2 is arranged on the inner wall of the refrigerating chamber along the height direction, an air outlet 4 communicated with the air duct 2 is arranged at the top of the refrigerating chamber, an air return opening 5 communicated with the air duct 2 is arranged at the bottom of the refrigerating chamber, and an evaporator 3 is arranged at the air outlet 4. According to the air-cooled refrigerator provided by the invention, the air duct 2 along the height direction is arranged on the inner wall of the refrigerating chamber, the air outlet 4 is arranged at the top of the refrigerating chamber, the air return opening 5 is arranged at the bottom of the refrigerating chamber, the evaporator 3 is arranged at the air outlet 4, so that cold air subjected to heat exchange through the evaporator 3 flows into the refrigerating chamber through the air outlet 4, the cold air naturally convects from top to bottom, food is refrigerated in the refrigerating chamber and simultaneously becomes relatively hot air, then the cold air flows into the air duct 2 through the air return opening 5 at the bottom of the refrigerating chamber and returns to the evaporator 3 through the air duct 2, and a cycle is completed.
