PURPOSE:To prevent uneven temperature of a freezer chamber from occurring by providing an exhaust fan in a partition wall as opposed to a cooling unit to supply a stable cool air to a cold storage chamber while preventing diffusion of the return cool air into a freezing chamber. CONSTITUTION:A cool air heat exchanged with a cooler 6 is blown off at a discharge port 9 with a freezing fan 7 and circulated forcibly through a freezing chamber 3 to cool the freezing chamber 3. The cool air from the freezing chamber 3 passes through a suction duct 14 at a cool air introduction port 12 of a partition wall 2 and supplied to the cold storage chamber 4 at a discharge port 13. The return cool air of the cold storage chamber 4 flows out at an inlet opening via a return duct and is mixed with a return cool air of the freezing chamber 7 near a suction port 10 to be sucked from the suction port 10 without being diffused into the freezing chamber 3. Again, the air is heat exchanged with the cooler 6 to repeat a cool air circulating operation. |
