Split air supply device and refrigerator

Abstract

The invention provides a branch air supply device and a refrigerator. Wherein, the branch air supply device includes: a housing, which has a plurality of air supply ports; a plurality of baffle plates, each baffle plate is installed at one air supply port; a plurality of transmission assemblies, each transmission assembly has a second rotating member and The second transmission mechanism; the first transmission mechanism is configured to transmit the rotational motion of the corresponding second rotating member to the baffle; the driving device has a driving source and a first transmission mechanism, and the first transmission mechanism is configured as one of the output of the driving source The movement is transmitted to a plurality of second rotating members; and the first transmission mechanism has a first rotating member; and a gear position sensing device configured to detect the position when the first rotating member stops rotating, so as to Determine the air outlet status of each air outlet. The cold air can be reasonably distributed to enhance the freshness preservation performance and operating efficiency of the refrigerator; and the control is simple, the adjustment is convenient, the adjustment speed is fast, 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.
