Branch air supply device and refrigerator

Abstract

The invention provides a branch air supply device and a refrigerator. The branch air supply device comprises a shell, a plurality of baffles, a plurality of transmission components, a driving device and a gear position sensing device. The shell comprises a plurality of air supply outlets; each baffle is installed at one air supply outlet; each transmission component is provided with a second transmission member and a second transmission mechanism; a first drive mechanism is configured to transfer the rotary motion of the corresponding second transmission member to the baffles; the driving device comprises a drive source and the first drive mechanism, the first drive mechanism is configured to transfer a motion output from the drive source to the second transmission member, and the first drive mechanism is provided with a first transmission member; and the gear position sensing device is configured to detect the position of the first transmission member when the rotation stops so as todetermine the air outlet status of each air supply outlet according to the position of the first transmission member when the rotation stops. Cool air can be reasonably distributed to enhance the fresh-keeping performance and operating efficiency of the refrigerator; and the control is simple, the adjustment is convenient, the adjustment speed is high, and the adjustment 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.
