Abstract

The invention provides a branching air supply device. The branching air supply device comprises a shell, an adjusting piece, a driving device and a pre-tensioning force exerting device, wherein the shell is provided with at least one air inlet and a plurality of air outlets, the adjusting piece is provided with at least one shielding portion, at least one of the shielding portions is rotationally arranged inside the shell to be configured for shielding the air outlets in a controllable mode, and the air outlet area of each air outlet can be adjusted; the driving device is configured to be capable of driving the adjusting piece to rotate; the pre-tensioning force exerting device is installed between the adjusting piece and the shell, and the pre-tensioning force exerting device is configured to be capable of exerting pre-tensioning force opposite to the rotating direction on the adjusting piece at least when the adjusting piece rotates in one rotating direction. The branching air supply device and a refrigerator are capable of conducting reasonable allocation on cool air according to the cooling capacity requirements of different storage rooms or the cooling capacity requirements of different storage space of the same storage room, so that the freshness retaining performance and the operating efficiency of the refrigerator are improved, and the stability can be kept in the adjusting process.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a branch air supply device for a 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. [0003] Similarly, in order to optimize the storage space, a single storage ...
