PROBLEM TO BE SOLVED: To provide a heat insulation cabinet capable of dispensing with bending of a vacuum heat insulation panel in a bent portion of a peripheral wall section, ensuring the high reliability of a heat insulation performance, and avoiding a cost increase.SOLUTION: A heat insulation cabinet 1 for heat insulation by providing vacuum heat insulation panels (6, 10, 13) in peripheral wall portions (1a, 1b, 1e), respectively, is configured such that a foam heat insulation material 7 is filled in each of bent portions 14 and 24 of the wall portions (1a, 1b, 1e). With this configuration, it is unnecessary to provide the vacuum heat insulation panels (6, 10) to be bent in the bent portions 14, 24, and a problem of breaking of the vacuum heat insulation panels (6, 10) due to the bending can be avoided, so that it is possible to obtain the high reliability of a heat insulation performance by the vacuum heat insulation panels (6, 10). Furthermore, the number of man-hours does not increase due to the bending of the vacuum heat insulation panels (6, 10) and a cost increase can be avoided.SELECTED DRAWING: Figure 1 |
