Branching air feeding device and refrigerator

Abstract

The invention provides a branching air feeding device and a refrigerator. The branching air feeding device comprises a shell, a plurality of baffles, a plurality of transmission assembles and a driving device; the shell is provided with a peripheral wall part, and a plurality of air feeding openings are formed in the peripheral wall part; and each baffle is rotationally installed at one air feeding opening, each transmission assembly is provided with a rotating gear and a first transmission mechanism, each first transmission mechanism is allocated to transfer rotary motion of the correspondingrotating gear to the corresponding baffle, and therefore the baffle is static or rotates; and the driving device is provided with an inner gear ring, each rotating gear is installed in the inner gearring and is meshed with the inner gear ring, so that the multiple rotating gears can be driven to rotate while the inner gear ring rotates. In this way, the flowing way and the flow of cold air can be adjusted in a unified manner, the cold air is reasonably allocated, and the freshness keeping property and the running efficiency of the refrigerator are strengthened; and control is simple, adjustment is convenient, the adjusting speed is high, and the 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...

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.
