REFRIGERATOR

PROBLEM TO BE SOLVED: To solve problems on degradation of heat insulating efficiency found in a case when defrosting water leaks without flowing down into a dew receiving pan by some reason that as the inner box shape receiving the dew receiving pan is the flat face not having a draining route, ice is attached as the defrosting water is diffused on the flat face and cooled, or the defrosting water impregnates into a foam insulation from a gap between the inner box and the dew receiving pan, and further from a gap with the inner box in which a drain pipe is penetrated. SOLUTION: This refrigerator has side drainage channels 50 at both wall sides of the inner box 33 receiving the dew receiving pan 40, and further the flat face 47 around a through hole 45 of the inner box 33 and its outer step 48 have difference in height, so that the defrosting water leaking to the dew receiving pan 40 does not intrude into the through hole 45, a foam insulation side is prevented from being impregnated with water, and the degradation of heat insulating efficiency can be prevented.
