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 a rotating disc, a driving device for controlling the rotating disc to rotate and at least two temperature control chambers; each temperature control chamber comprises an air supply port and an air return port; the rotating disc is provided with a communicating port corresponding to the air return ports; and at least one temperature control chamber is provided with a heating device. When the temperature control chambers need to be heated, the heating devices can conduct heating according to the temperature requirements of the temperature control chambers, temperature control can be carried out on other temperature control chambers through the driving device and the rotating disc, therefore, different temperature control can be conducted on the different temperature control chambers at the same time, the temperature change range of the temperature control chambers can be effectively expanded, and wide-range temperature adjustment of the temperature control chambers is realized.

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 realized by flip-type electric dampers combined with air ducts. In this way, the temperature adjustment range of each temperature zone is relatively small. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a return air temperature control mechanis...
