[0002] Existing air-cooled refrigerators generally have an air duct back plate at the rear of the refrigerator liner, the front of the air duct back plate is the storage compartment, and the rear of the air duct back plate is the evaporator compartment. In addition, air supply ports and return ports are provided on the air duct back plate, so that the cold air in the evaporator compartment can flow into the storage compartment through the air supply ports, exchange heat with the storage in the storage compartment, and then flow back to the evaporator compartment through multiple return ports, thereby realizing air circulation.

[0003] However, this method prevents the airflow from the air supply port to the storage room from flowing completely to the front of the storage room, so that most of the airflow flows downward in the middle of the storage room, and then flows back to the evaporator chamber from the return air port, and cannot flow to the entire storage room. The circulation area is very small, making the cooling capacity of the entire storage room unevenly distributed, that is, the temperature in the middle and end of the storage room is not the same, which is not conducive to the storage of food. In addition, if food is placed near the air outlet, the air outlet is blocked, which may cause the cold air to fail to circulate normally, affecting the cooling effect, and then affecting the storage and preservation of food.
