Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof, and the refrigerator comprises a first storage chamber, a second storage chamber with the temperature higher than that of the first storage chamber, a compressor, an evaporator chamber, an evaporator, a first air return duct, a first air door and an air feeder, the first air return duct communicates a first air return port of the first storage chamber with a first air supply port of the second storage chamber and an air inlet of the evaporator chamber through a first air door, and the first air door is provided with a first position where the first air return port communicates with the first air supply port. The first air door is further provided with a second position for communicating the first return air inlet with the air inlet of the evaporator chamber; the first air return duct can introduce return air of the first storage chamber into the second storage chamber to supply cooling capacity to the second storage chamber, so that the cooling capacity is utilized to the maximum extent, cooling capacity waste is reduced, meanwhile, the air return path of the first storage chamber is adjusted through one air return duct and one air door, the design is simplified, and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of refrigeration and freezing storage, in particular to a refrigerator and a control method thereof. Background technique [0002] Refrigerators generally have multiple temperature zones, which can provide users with different food storage requirements. In existing refrigerators, the cold energy in the cooler temperature zone is directly returned to the evaporator, and there is a waste of cold energy, especially for those with deep cold space. The temperature of the cryogenic space can reach -40°C. If the cold energy is directly returned to the evaporator, the waste of cold energy will be more serious. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a refrigerator and a control method thereof that solve at least the above-mentioned problems. [0004] A further object of the present invention is to increase the probability that the first storage compartment and th...

Problems solved by technology

[0002] Refrigerators generally have multiple temperature zones, which can provide users with different storage requirements for food materials. In existing refrigerators, the cooling capacity in the colder temperature zone is directly returned to the evaporator, and there is a waste of cooling capacity, especially for those with cryogenic space. For refrigerators, the temperature in the cryogenic space can reach -40°C. If the cooling capacity is directly returned to the evaporator, the cooling capacity will be wasted more seriously.
