<p>PROBLEM TO BE SOLVED: To provide a refrigerator with improved heat insulation property by increasing coverage of a vacuum heat insulation material while maintaining bending quality of a heat radiation pipe.SOLUTION: The refrigerator comprises a heat radiation pipe side 18S arranged inside an outer case of a heat insulation box, and a vacuum heat insulation material 21 arranged on an interior side of the heat radiation pipe side. The vacuum heat insulation material has a recess groove, is provided with a local groove 22e formed at least from an end face of the vacuum heat insulation material and not crossing with the vacuum heat insulation material, and is constituted so that a bride-bending part 18S-2 of the heat radiation pipe inserted into the local groove. Thereby, the bridge-bending part of the heat radiation pipe is covered to improve coverage of the vacuum heat insulation material. Also, bridge-bending of the heat radiation pipe from a side face of the heat insulation box to the other face, for example a ceiling face can be done without problems, so as to increase coverage of the vacuum heat insulation material and improve heat insulation property while maintaining bending quality of the heat radiation pipe.</p> |
