Split air supply device and refrigerator

Abstract

Disclosed are a branch air supply device and a refrigerator. The branch air supply device (400) comprises: a housing (410) with a plurality of air supply outlets (411); a plurality of baffles (420), each baffle (420) rotatably mounted at one air supply outlet (411) with a first position and a second position; a plurality of transmission assemblies, each transmission assembly having a rotational member (430), a bevel gear (434), an engaging and disengaging mechanism (433) and a reset device (432), wherein one side of the rotational member (430) is a discontinuous bevel gear structure cooperating with the bevel gear (434), the bevel gear (434) is connected to the corresponding baffle (420) via the engaging and disengaging mechanism (433), the engaging and disengaging mechanism (433) is configured to not prevent the rotation of the bevel gear (434) and the rotational member (430) when the corresponding baffle (420) is stationary, and the reset device (432) is mounted on the baffle (420) and configured to urge the corresponding baffle (420) to return to the first position when the bevel gear (434) and the rotational member (430) are disengaged; and a driving device. By means of the invention, it is convenient to uniformly adjust a flow path and flow rate of cold air, and rationally distribute the cold air to enhance the fresh-keeping performance and operating efficiency of the refrigerator; the invention is also easy to control and convenient to adjust, and has a fast adjusting speed and a high adjusting 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...

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.
