Shunt air-supplying device and refrigerator

Abstract

The invention provides a shunt air-supplying device and a refrigerator. The shunt air-supplying device comprises a shell provided with a plurality of air-supplying openings, a plurality of baffles, aplurality of transmission assemblies and a driving device. Each baffle is provided with a first position and a second position. Each transmission assembly is provided with a rotating piece, a bevel gear, a clutch mechanism and a reset device. One side of each rotating piece is a discontinuous bevel gear structure matched with the corresponding bevel gear. The bevel gears are connected with the baffles through the clutch mechanisms. The clutch mechanisms are configured not to stop rotation of the bevel gears and the rotating pieces when the baffles are stationary. The reset devices are mountedto the baffles to prompt the baffles to return to the first positions. Each rotating piece is provided with a tooth meshing with another rotating piece to transmit rotation of one rotating piece to the multiple rotating pieces. A flow path and the flow quantity of cold air can be conveniently and uniformly adjusted, the cold air is reasonably distributed, and the fresh keeping property and the running efficiency of the refrigerator are enhanced; and control is simple, adjusting is convenient, the adjusting speed is high, and the adjusting accuracy rate 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.
