Branched air supply device and refrigerator

Abstract

The invention provides a branched air supply device and a refrigerator. The branched air supply device comprises a shell, multiple baffle plates, multiple transmission modules and a driving device, wherein the shell is provided with multiple air supply ports; each baffle plate is rotationally mounted in one air supply port, and is rotated in different rotating positions to adjust exhaust areas ofcorresponding air supply ports; each transmission module is provided with a rotating piece and a first transmission mechanism; each first transmission mechanism is configured to transfer a rotating motion of the corresponding rotating piece to a baffle plate so as to stop or rotate the baffle plate; the driving device is provided with a driving source and a second transmission mechanism; and the second transmission mechanism is configured to transfer a motion output by the driving source to the multiple rotating pieces so as to stop or rotate each rotating piece. The branched air supply deviceis convenient for unified adjustment of a flowing way and a flow of cold air, reasonably distributes the cold air, improves the preservation performance and the operation efficiency of the refrigerator, and is simple in control, convenient to adjust, high in adjustment speed and high in adjustment accuracy.

Description

technical field [0001] The invention relates to the field of refrigerator storage, in particular to a branch air supply device and a refrigerator. Background technique [0002] At present, the air-cooled refrigerator generates cold air through a built-in evaporator, and the cold air circulates through the air duct to each storage compartment of the refrigerator to achieve cooling. For air-cooled refrigerators, the freshness of food largely depends on whether the air circulation in the storage room is reasonable. If the cold air flows randomly through the air duct, it is easy to cause too much or insufficient air volume entering the storage rooms, making the temperature distribution in the storage rooms unbalanced, and the operating efficiency of the refrigerator will also be reduced. Therefore, it is necessary to accurately distribute and control the flow of cold air entering each storage compartment. Similarly, in order to optimize the storage space, a single storage room...

AI Technical Summary

Problems solved by technology

Similarly, in order to optimize the storage space, a single storage room is generally divided into multiple detailed storage spaces by storage devices such as shelves or drawers. The cooling capacity is also different. Therefore, if the cold air directly enters the storage room from somewhere in the storage room without control, it will cause some storage spaces to be overcooled and some storage spaces to have insufficient cooling capacity.
