  • 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.
  • 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.
  • the split air supply device 400 and/or the in-line split air supply device in the refrigerator of the embodiment of the invention can realize the adjustment of the air outlet air passage and the air volume, and the cold air outlet where the cold air is needed in the refrigerator. It does not need cold air to close, thus controlling the constant temperature in the refrigerator, providing the best storage environment for the food in the refrigerator, reducing the nutrient loss of the food, and reducing the power consumption of the refrigerator and saving energy.
