Description

Branch air supply device and refrigerator with the branch air supply device

technical field

The invention relates to a refrigeration device, in particular to a branch air supply device and a refrigerator with the branch air supply device.

Background technique

In recent years, with the improvement of people's living standards and the enhancement of environmental awareness, the requirements for refrigerators have shifted from satisfying low-temperature refrigeration to keeping food fresh. Therefore, air-cooled refrigerators are gradually favored by people. For air-cooled refrigerators, the freshness of food depends to a large extent on the air circulation in the storage room of air-cooled refrigerators and the temperature difference between various parts in the box. The air circulation in the box is reasonable, and the smaller the temperature difference, the better the freshness preservation performance of the refrigerator. The key component that determines whether the air circulation of the refrigerator is reasonable is the air duct, which controls the air direction and flow of the refrigerator, and directly determines the refrigeration and preservation effect of the refrigerator. In addition, 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. Therefore, the uncontrolled cold air directly enters the storage room from somewhere in the storage room, which will cause the problem of overcooling of some storage spaces and insufficient cooling capacity of some storage spaces.

In the current design of the air passage of air-cooled refrigerators on the market, some air-cooled refrigerators use the air from the freezer to directly pass it to the freezer. There is no air door between the freezer and the refrigerator in general air-cooled refrigerators, and the air passages on the air duct are all connected in series. The temperature has been in a state of cyclic fluctuations, that is, the temperature in the refrigerator has been changing, which greatly affects the freshness preservation performance of the refrigerator. There are also some air-cooled refrigerators that place the evaporator in a separate storage room, use a complex air duct system to connect the storage room of the evaporator with each storage room, and use the fan to transport the cold air generated by the evaporator to each storage room. A control device (such as an electric damper) is set in the air duct to open and close the air duct entering each storage compartment, or to adjust the air volume entering each storage compartment. However, this structure is more complicated and not convenient for unified control. And it is impossible to distribute and regulate the cold air entering each storage room according to the cooling demand of each storage space.
