PROBLEM TO BE SOLVED: To perform uniform cooling of the other storage chamber. SOLUTION: A part of cold air in a freezing chamber F is induced and supplied to a bottom 30 through operation of a preservation chamber fan 12 and by effecting reflux of it from a ceiling part 31 to the freezing chamber F side, a preservation chamber S is cooled. A pair of circulation ducts 26 are longitudinally arranged at a side wall 25 on the opposite side to a partition wall 2 of the preservation chamber S and on the this side and the deep side between which the preservation chamber fan 12 is nipped, and a circulation fan 29 is provided at an outlet 28 formed in an upper end. A part of cold air supplied to the bottom 30 of the preservation chamber S is sucked through inlets 27 of the two circulation ducts 26 and flows to above, and supplied through the outlet 28 and flows across the ceiling part 31 toward the partition wall 2 side. The cold air is caused to effect reflux through a cold air return port 11 to the freezing chamber F side togetherwith cold air rising between the two circulation ducts 26. Cold air spreads even to the ceiling part 31, in which cold air hardly spreads and which is situated on the opposite side to the partition wall 2, and the interior of the preservation chamber S is evenly cooled. |
