Description
Technical Field
The utility model belongs to the technical field of refrigeration equipment, and particularly provides an air-cooled refrigerator.
Background
The refrigerator mainly comprises a storage chamber, an evaporator, an evaporation fan and the like. The storage chamber is used for placing stored objects such as food and the like, the evaporator is used for cooling air around the evaporator, and the evaporation fan is used for conveying the air cooled by the evaporator to the storage chamber and blowing the air to the food in the storage chamber.
When freezing/refrigerating food materials, it is also often desirable for the food materials to be as fresh-kept as possible. The food materials are required to be cooled rapidly, so that the freezing/refrigerating effect of the food materials is realized; meanwhile, the moisture content of the food material needs to be reduced as little as possible so as to realize the fresh-keeping effect of the food material. However, when the food material is rapidly frozen/refrigerated, the flow rate of the cold air blowing to the food material is large, so that a large amount of water on the food material can be taken away, and the water content of the food material is reduced; in order to reduce the loss of moisture in the food material, the flow rate of air needs to be reduced, and the effect of quickly freezing the food material cannot be realized.
Therefore, a new refrigerator is urgently needed to ensure the freshness of the food materials so as to meet the daily requirements of freezing/refrigerating the food materials for users.

Further, the rotation speed of the first fan is lower than that of the second fan, so that the second fan is used for forcing the air in the air supply duct to enter the storage chamber from the side blowing outlet and preventing the air in the storage chamber from flowing back to the air supply duct from the direct blowing outlet.
Further, the fresh air inlet includes direct-blow fresh air inlet and side-blow fresh air inlet, first fan is installed direct-blow fresh air inlet department and runs through direct-blow fresh air inlet, in order to drive air in the air supply duct is followed direct-blow fresh air inlet gets into the apron wind channel, the second fan is installed side-blow fresh air inlet department and runs through the side-blow fresh air inlet, in order to drive air in the air supply duct is followed side-blow fresh air inlet gets into the apron wind channel.
Further, the cover plate air duct comprises a direct blowing air duct and a side blowing air duct, the direct blowing air duct communicates the direct blowing air inlet hole with the direct blowing air outlet, and the side blowing air duct communicates the side blowing air inlet hole with the side blowing air outlet.
