Return air temperature control mechanism, return air temperature control method, operation control device and refrigerator

Abstract

The invention discloses a return air temperature control mechanism, a return air temperature control method, an operation control device and a refrigerator. The refrigerator is provided with a refrigeration evaporator and a refrigeration area air inlet, the return air temperature control mechanism comprises at least two temperature control chambers, a heating device and a refrigeration evaporator air duct, and each temperature control chamber comprises an air supply port and an air return port. The air return ports, the air supply ports and the refrigeration area air inlet are sequentially arranged in the air supply direction of the refrigeration evaporator air duct, the heating device is arranged in the refrigeration evaporator air duct, the refrigeration evaporator is located between the air supply ports and the air return ports, and the heating device is located in front of the air supply ports in the direction from the air supply ports to the refrigeration area air inlet. When the temperature of the temperature control chambers is reduced, the temperature of the airflow entering the refrigeration area is increased by the heating device, the temperature of the refrigeration area cannot be too low even if the temperature reduction amplitude of the temperature control chambers is larger, the temperature change range of the temperature control chambers can be effectively expanded, wide-range temperature adjustment of the temperature control chambers is achieved, and different storage requirements are met.

Description

technical field [0001] The invention relates to the field of refrigerators, more specifically, to a return air temperature control mechanism, a return air temperature control method, an operation control device and a refrigerator. Background technique [0002] With the subdivision of temperature zones brought about by technology upgrades and the increasing abundance of food materials that users can purchase, multiple refined storage spaces are needed, and the demand for refrigerators with multiple temperature zones to achieve different functions is imminent. Existing refrigerators are generally provided with a refrigerated area and a compartment, and the refrigerated area and the compartment are arranged in the refrigerated compartment. When the compartment needs to be cooled, the refrigerated area will also be cooled accordingly. , the temperature of the temperature-controlled compartment can vary in a small range, which cannot meet different storage requirements.
