PURPOSE:To enable a refrigerator effective inner volume to be widely utilized, realize a small-sized refrigerator and improve an efficiency in operation of the refrigerator by a method wherein sensor means for sensing a position of a rotor is provided, each of rotors for a cold air inlet port and a cold air outlet port is stopped and then both inlet and outlet ports can be opened or closed by a seal part. CONSTITUTION:A cold air inlet port 4 communicated with a cold air inlet port and two outlet ports 5, 6 communicating with the cold air inlet port are disposed on the same circumference spaced apart by 90 deg.. It has a rotatable rotor 1.2 and a seal 1.5 for opening or closing the inlet port 4 and outlet ports 5, 6, and a lead switch 18 for sensing a position of the rotor. Stopping of the rotor 12 at each of the inlet port and outlet port can be carried out by a control circuit. Accordingly, it is satisfactory that a single motor is applied for performing a control of temperature in the two rooms. This device is thin in its size, has a simple structure and becomes a simple damper opening or closing device. |
