PURPOSE:To reduce condensation and freezing of a rotor by mounting a cold air inlet part of a housing of a cold air flow rate control device so as to be located downward of a cold air outlet part. CONSTITUTION:A cold air inlet part 14 and one or two cold air outlet parts 15a, 15b are provided at a cold air flow inlet 5 in the same housing 10. Further, a rotor 19 for opening and closing the cold air inlet part 14 and the cold air outlet parts 15a, 15b is rotatably provided in the housing 10. Thereupon, the cold air inlet part 14 is mounted downwardly of the cold air outlet parts 15a, 15b. As a result, cold air from the cold air inlet part 14 once goes downward to the cold air inlet part 14 and rises passing through the inside of the housing 10, and is further discharged from outlet parts 15a, 15b. Thus, hot air in the refrigerator when the inlet part 14 is closed fills the upper part of the housing 10 without directly making contact with the cold air, preventing condensation and freezing from being produced. |
