Abstract
PURPOSE: To improve a space efficiency by controlling a cam installed between two flaps for opening/closing the flaps to an arbitrary rotating position, thereby temperature controlling two cold storage chambers by one damper opening/ closing apparatus. CONSTITUTION: A driver 18 rotates a cam 16 via a shaft 18a according to temperatures of first and second cold storage chambers 20, 21 to oscillate first and second flaps 14, 15. Thus, discharge ports 13a, 13b of a case 13 are opened or closed and whether cold gas introduced into the damper opening/closing apparatus 22 from a refrigerating chamber 19 via a passage 23 is fed to first and second passages 24, 25 or not is controlled. If the rotating position of the cam 16 is A, the flaps 14, 15 and the ports 13a, 13b of the case 13 are opened, while if it is B, the flap 14 and the port 13a are opened, but the flap 15 and the port 13b are closed. In the case of C, the flaps 14, 15 and the ports 13a, 13b are closed. In the case of D, the flap 14 and the port 13a are closed, and the flap 15 and the port 13b are closed.
