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 return air temperature control mechanism comprises an evaporator, an evaporator air duct and a refrigeration fan, and the refrigeration fan and the evaporator are arranged in the evaporator air duct; the portion, in front of the evaporator in the air supply direction of the refrigeration fan, of the evaporator air duct is a first air duct, the portion, behind the evaporator in the air supply direction of the refrigeration fan, of the evaporator air duct is a second air duct, and the refrigeration fan is arranged in the second air duct; the return air temperature control mechanism further comprises at least two temperature control chambers, a rotating disc and a driving device; the temperature control chambers comprise air supply ports and air return ports; the rotating disc comprises a communicating port corresponding to the air return ports; and the driving device controls the rotating disc to rotate according to the temperature requirements of the temperature control chambers to enable the communicating port to communicate with the air return port of the temperature control chamber corresponding to the temperature control request. Opening and closing of the air return ports of the multiple temperature control chambers are controlled through the rotating disc, the temperature control requests of multiple temperature areas can be met, and the temperature adjusting efficiency of the temperature control chambers can be improved.

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] As user technology upgrades bring temperature zone subdivision and users can purchase more and more food materials, multiple refined storage spaces are needed, and the demand for refrigerators with multiple temperature zones to achieve different functions is imminent. At present, most of the methods for realizing multi-temperature zones are implemented by flipping electric dampers combined with air ducts. Especially when realizing temperature control of multiple compartments, multiple dampers need to be installed. This structural design takes up too much space and is expensive. The temperature regulation of the temperature-controlled compartment is less efficient. Contents of the invention [0003] The present inven...
