PROBLEM TO BE SOLVED: To solve a problem that cold air is hardly circulated to a refrigerating chamber due to a pressure loss incurring by a damper device, to suppress the increase of an electric charge required for defrosting, and to suppress the increase of the temperature of a refrigerating chamber after completion of defrosting as much as possible. SOLUTION: The outlet side of a common duct 31 where a cooler 30 is disposed in a partition wall 22 is branched. A first cold air circulation route is formed that one thereof connected to a blower 36 for cooling a refrigerating chamber forms a first cold air circulation route formed that cold air is supplied through air outlets 42 and 43 of a discharge duct 41 for refrigeration to an ice making chamber 7, a temperature change chamber 8, and a refrigerating chamber 9 and returned to the common duct 31 through an air inlet 44 formed in the under surface of the front of the partition wall 22. A second cold air circulation route is formed that the other thereof is connected to a blower 47 for cooling a refrigerating chamber disposed in a discharge duct 46 for refrigeration formed toward above along a vegetable chamber 6 and the back of a refrigerating chamber 5. Cold air is supplied in the refrigerating chamber 6 from above of a front through an air outlet 48 of the discharge duct 46, and returned to the common duct 31 through an air inlet 49 formed in the upper surface of the partition wall 22. |
