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 drive device. The shell is provided with a peripheral wall portion, and multiple air supply openings are formed in the peripheral wall portion. Each baffle is rotationally mounted at one corresponding air supply opening. Each transmission assembly is provided with a rotating gear and a first transmission mechanism. Each first transmission mechanism is configured to transmit rotating motion of the corresponding rotating gear to the corresponding baffle. One rotating gear is engaged with another rotating gear so that rotation of the corresponding rotating gear can be transmitted to the multiple rotating gears. Theconnecting lines of the projections of the rotating axes of the multiple rotating gears in the reference plane perpendicular to the rotating axes form a polygon. The drive device is provided with a drive gear, and the drive gear is engaged with one rotating gear. Cold air can be conveniently distributed reasonably, and the freshness keeping performance and operation efficiency of the refrigeratorcan be enhanced; and control is simple, 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.
