Refrigerator and branch air supply device for refrigerator

Abstract

The invention relates to a refrigerator and a branch air supply device for a refrigerator, wherein the branch air supply device comprises: a housing that has an air inlet, a first air outlet and a plurality of second air outlets; a retaining board that is rotatably mounted at the first air outlet; an adjusting member that is rotatably disposed inside the housing to fully or partially cover or fully expose all second air outlets from different rotation positions, thereby adjusting the air outlet area of each second air outlet; and a linkage that is configured to transmit rotational motion of the adjusting member to the retaining board, thereby moving the retaining board to open or close the first air outlet; in addition, the invention also provides a refrigerator having the branch air supply device. The refrigerator and the branch air supply device for the refrigerator may allow the opening and closing of the first air outlet and the multiple second air outlets to be controlled in the same time, thereby reducing the control complexity of the refrigerator.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a refrigerator and a branch air supply device for the refrigerator. Background technique [0002] Generally speaking, an air-cooled refrigerator generates cold air through a built-in evaporator, and the cold air circulates through an 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...

Problems solved by technology

However, most refrigerators with dual-system refrigerators are equipped with a drying room in addition to multi-layer shelves, and the drying room needs to control the air supply separately, usually by setting a control device (such as an electric damper) in the air duct to control the drying. The opening and closing of the air supply duct in the room requires the control of the electric damper and the branch air supply device, which significantly increases the complexity of the control of the refrigerator, and also increases the power consumption of the refrigerator.
