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 one temperature control chamber group; the temperature control chamber group comprises two adjacent temperature control chambers, and the two temperature control chambers are provided with a semiconductor refrigerating assembly in a penetrating manner; the semiconductor refrigerating assembly comprises a hot end and a cold end, the hot end faces one temperature control chamber, and the cold end faces the other temperature control chamber; each temperature control chamber comprises an air supply port and an air return port; and the rotating disc is provided with a communicating port capable of corresponding to the air return ports. The semiconductor refrigerating assembly can control the temperature of the cold end and the hot end according to the temperature requirements of the temperature control chambers, therefore, different temperature control can be carried out on the plurality of different temperature control chambers at the same time, the temperature change range of the temperature control chambers can be expanded, and wide-range temperature adjustment of the temperature control chambers is achieved.

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 adjusted by transferring the cooling capacity of the evaporator to the temperature-controlled compartment through the damper, and the range of temperature control is limited. 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 temperatu...
