PURPOSE:To devise to change the capacity rate between a freezing and a refrigerating chamber and to strengthen a partition wall by equipping a partition duct plate in a cold air blowoff part to a freezing chamber and a switching damper in a pressure chamber and shaping a damper frame and the partition wall in one body. CONSTITUTION:When a switching damper 30 is operated to connect a passage 28 with a pressure chamber 25, cold air is mostly blown off to a freezing chamber 5, and the remainder is conducted through a passage 26, the pressure chamber 25, and the passage 28 to be returned to a cooler 11. The cold air in the freezing chamber 5 is sucked into a passage 21 through a suction port 20, and distributed by a damper thermostat 23; on one way it is conducted through a passage 22 to cool a freezing-refrigerating chamber 6, and returned to the cooler 11 through a suction port 29, and on another way, it is respectively returned to the cooler 11 through the pressure chamber 25 and the passage 28, making the switching chamber 6 a refrigerating chamber. In this construction, a partition wall is shaped in one body with a damper frame, and the sliding part of the damper is kept higher than the bottom of the partition wall for strengthening the partition wall and preventing the sliding part of the damper from freezing. |
