Background
The air-cooled refrigerator has the main advantages of no frost, higher freezing speed, more uniform refrigeration and better food fresh-keeping property. The existing air-cooled refrigerator mostly adopts unilateral air supply and air return, and the position of an air supply port is often near the edge of a cabinet opening at the upper part of a freezing chamber, so that the air return at the bottom of the upper air supply is theoretically wanted to be realized, and an air flow circulation is formed along the inner wall in the freezing chamber. However, when the space in the freezer compartment is occupied by the frozen articles, the circulation of air flow in the freezer compartment is affected, resulting in a deterioration of the uniform freezing effect of the whole freezer compartment (particularly, the center portion of the freezer compartment). The reason for this is that the air supply and the air return are all on the same side wall, the circulation of the air flow is single, and the phenomenon that the frozen articles block the circulation path of the air flow due to the random placement of food in personal habit when a user uses the air conditioner cannot be avoided.
