Abstract

See full text

The present invention provides a refrigerator with improved refrigerator box strength and high heat insulating performance, which is configured such that external deformation due to entry of air into a vacuum heat insulating material, the entry of air being caused by aging degradation, is prevented. The present invention includes: a heat-insulated box including an inner casing and an outer casing, in which space between the inner casing and the outer casing is filled with a foamed heat insulating material; and a vacuum heat insulating material disposed in at least a side wall of the heat-insulated box together with the foamed heat insulating material, the vacuum heat insulating material including an outer skin material, the outer skin material including at least a core material and being decompression-sealed. The vacuum heat insulating material includes a gas adsorbent. Since the vacuum heat insulating material including the gas adsorbent is included in the side wall, which tends to be greatly distorted among the heat insulating walls of the refrigerator, the rigidity of the side wall is improved and aging degradation of the vacuum heat insulating material is suppressed. As a result, the rigidity of the heat-insulated box can be maintained for a long term, and external deformation of the outer casing of the body can be prevented.
