PURPOSE:To increase cooling capacity and to prevent the melting of frozen food by providing the suction part of the cold air introducing duct for introducing the cold air of a freezing chamber in the emitting over of the emitted cold air of the freezing chamber and providing the emitting part of a cold air return duct to the suction part of the cooling fan of the freezing chamber. CONSTITUTION:A freezing chamber 10 is cooled by the air cooled by a cooling fan 15 and an evaporator 14. A part of cold air is guided to a suction part 30 and a cold air introducing duct 28 corresponding to the controlled temp. of a cold-storage chamber 11 by a damper 17. At this time, since the pressure of the suction part 30 is same as that in the emitting cover 31 provided on the leeward side of the cooling fan 15, the pressure is raised by the dynamic pressure of the cooling fan 15 and the blow amount of cold air to the duct 28 increases. Further, since the damper 17 is provided on the leeward side of the stirring fan 21 in the cold-storage chamber 11, the suction amount of cold air is increased by negative pressure. By this constitution, a large amount of air is sent in the cold-storage chamber and the melting of the food in the freezing chamber is prevented. |
