In some embodiments, the plurality of air outlet ducts are configured to cause airflow exiting the air duct assembly 200 to enter a plurality of storage compartments of the refrigerator, that is, each of the air outlet ducts is connected to one of the storage compartments. For example, the air supply port 311 of the branch air supply device 300 may be three, such as the first port, the second port, and the third port; the air outlet duct may be three; and the plurality of storage compartments include the first storage. a compartment, a second storage compartment, and a third storage compartment. When the first storage compartment requires cold air, and the second and third storage compartments do not require cold air, the second port and the third port of the split air supply device 300 may be in a closed state, the first port 1 Is open.

In other embodiments, the plurality of air outlet ducts may be configured to allow airflow exiting the air duct assembly 200 to enter the plurality of locations on the chamber wall of a storage compartment (eg, a refrigerating compartment) of the refrigerator, respectively. Storage room. For example, the air supply port 311 of the branch air supply device 300 may be three, such as the first port, the second port, and the third port; the air outlet air channel may be three, such as the first air channel that communicates with the first port. a second air passage communicating with the second port and a third air passage communicating with the third port. The first air passage may have two or four cold air outlets symmetrically disposed at an upper portion of the rear wall of the refrigerating chamber. The first air passage may have a cold air outlet disposed at a lower portion of the rear wall of the refrigerating chamber. The second air duct may be located between the first air duct and the second air duct, and has one or two cold air outlets disposed in the middle of the rear wall of the refrigerating chamber. Further, the two compartments can also be used to divide the refrigerating compartment into three small storage spaces, each of which is in communication with a small storage space. In this embodiment, the plurality of storage compartments may also include other storage compartments, such as a quick freezing compartment, a freezer compartment.

The split air supply device 300 in the refrigerator of the embodiment of the invention can realize the regulation of the air outlet air passage and the air volume, and the cold air outlet where the cold air is needed in the refrigerator can be turned off, and the cold air is not required to be closed, thereby controlling the refrigerator. The constant temperature provides the best storage environment for the food in the refrigerator, reduces the nutrient loss of the food, and can reduce the power consumption of the refrigerator and save energy.
