Branching air supply device and refrigerator

Abstract

The invention provides a branching air supply device and a refrigerator. The branching air supply device comprises a shell, multiple baffles, multiple transmission assemblies and a driving device. Theshell is provided with a circumferential wall portion which is provided with multiple air supply ports, each baffle is rotationally installed on one air supply port, each transmission assembly is provided with a rotating part and a first transmission mechanism, each first transmission mechanism is arranged to transfer rotary motion of the corresponding rotating part to one baffle so as to enablethe baffle to be static or rotated, the driving device is provided with a driving source and a second transmission mechanism, and the second transmission mechanism is arranged to transfer one motion output by a driving source to the multiple rotating parts so as to enable each rotating part to be static or rotated. The flow path and quantity of cold air can be conveniently adjusted in a unified mode, cold air is reasonably allocated, the preservation performance and operation efficiency of the refrigerator are improved, control is easy, adjustment is convenient, the adjusting speed is high, and adjusting accuracy is high.

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...

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.
