PURPOSE:To avoid a prohibition of circulation of cold air caused by ice blocks or damage to a supply fan by a method wherein the rear surface of a bottom plate disposed at an interface between a bottom region of a cold air passage and a storing chamber is provided with a slant surface inclined downward toward a water drain port and the lowest part is positioned ahead of the supply fan. CONSTITUTION:A slant plate 17 is disposed forwardly and downwardly at a rear surface of a bottom plate 4B with a spacing acting as a thermal insulation space being present thereat. The lowest part 19 of a slant surface 18 at the rear surface exposed to the cold air is formed at a front end positioned more forwardly than a drain port 16. Accordingly, in the event that frost T is adhered to the slant surface 18, the frost is guided to the lowest part 19 along a slant gradient, dripped onto the bottom wall 2B at the position spaced apart from a supply fan 7. The frost T on the bottom wall 2B is discharged out of the water drain port 16. |
