Abstract:
To provide a refrigerator while paying attention to a fact that there is a section where a foam heat insulation material is not required to be provided even on a top surface of a box body if a section where an influence of a foam heat insulation material on the strength is small is specified.SOLUTION: A refrigerator includes a box body having a vacuum heat insulation material and a foam heat insulation material put by in-place foaming between an outer box and an inner box. The foam heat insulation material is not positioned on part of the underside of the vacuum heat insulation material on a top surface of the box body. The foam heat insulation material is put between an inside lamp and/or a cord disposed on the top surface and located below the vacuum heat insulation material and the vacuum heat insulation material. Thereby, a refrigerator with a reduced filling amount of the foam heat insulation material can be achieved while the strength of the box body is secured.SELECTED DRAWING: Figure 6
