REFRIGERATOR WITH SWITCHING DEVICE FOR COLD AIR DISCHARGE PORT

PROBLEM TO BE SOLVED: To prevent the cooling efficiency of a refrigerator from decreasing by driving a switching member that is provided at a duct member for discharging a cold air from the cold air discharge port and where a number of ventilation holes that are provided at a duct member for discharging a cold air from the cold air discharge port so that the cold air discharge port can be closed when the defrosting of a heater is started and/or a door is opened. SOLUTION: A duct member 3 that is provided on the rear surface of a refrigeration room 1 and forms a cold air duct supplies a cold air that is ventilated through a number of cold air discharge ports 3a into the refrigeration room. A switching device including a switching member 6 for switching the cold air discharge ports 3a, a cam 7, and a drive motor 9 is installed in this kind of duct member 3. Also, the switching member 6 is arranged adhesively at the duct member 3, and a number of ventilation holes 5 corresponding to the cold air discharge port 3a are formed. When the switching member 6 rises due to the elevation motion caused by the rotation of the cam 7 driven by a driving motor 9, the cold air discharge port 3a is released. On the other hand, when the switching member 6 is lowered, the cold air discharge port 3a is closed. Then, the switching member 6 is closed when a refrigeration room performs a defrosting operation and the door is opened.
