PURPOSE:To make a clean cabinet which has no gas exhausting port in a back plate, by providing the gas exhausting port at the inner box side of a refrigerator, also providing the gas exhausting port and a groove at the central part of an inner foamed layer and filling the groove with a porous material. CONSTITUTION:When the cabinet body of a refrigerator is filled with a heat insulation material, it can be used for partitioning a kitchen by providing the exhausting port which evacuates the gas generated in time of forming the heat insulation material in an inner box side. In that case the gas exhausting port 10 and a groove 8 are provided at the central part of the inner layer 1 of a foam layer and the groove 8 is filled with a porous material 9. Accordingly, the exhausted gas of a bad efficiency is selectively and efficiently adsorbed by the direct contact of the inner box and the inner layer 1, the voidless formation of the heat insulation material is devised, the dent, etc. of the inner box at a low temperature is solved and the clean inner box which is free from an unevenness can be manufactured at the same time. |
