PROBLEM TO BE SOLVED: To enable a uniform cooling of the inside of a storing chamber without drying foods stored in the storing chamber. SOLUTION: A heat absorbing plate 13 is extended at a ceiling portion of a storing chamber S and a cold air passage 23 is defined above the heat absorbing plate 13, wherein cold air which is blown into the cold air passage 23 from a freezing chamber F is made to pass through the cold air passage 23 in an arrow direction. A plurality of heat absorbing fins 27 are mounted on a lower surface of the heat absorbing plate 13 in a spaced-apart manner along a flow direction of the cold air in a lower passage 24. These heat absorbing fins 27 gradually increase their heat absorbing areas in sequence corresponding to a distance from an inlet of the lower passage 24 toward an outlet of the lower passage 24. As the cold air passes through the cold air passage 23, the heat absorbing plate 13 and the heat absorbing fins 27 are cooled. Cold air is generated by a heat exchange with the heat absorbing plate 13 and the heat absorbing fins 27 and this cold air is gradually settled in the storing chamber S so as to cool the inside of the storing chamber S. Since foods receives no wind, a drying of foods can be restricted. Furthermore, since the heat absorbing fins 27 differ in their sizes, heat absorbing ability of the heat absorbing fins 27 can be equalized thus enabling a uniform cooling of the inside of the storing chamber S. |
