REFRIGERATOR
Document Type and Number:
Japanese Patent JP2016053472
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator which secures a heat insulation property and strength.SOLUTION: A refrigerator includes: a protrusion part 450 which is formed at a corner part of an inner box 750 of an inside surface of a side wall 790 and a back wall 730, and which is provided so as to protrude to a further front surface side than the inside surface of the back wall 730; a flat plate-like vacuum heat insulation material 400 which is provided between the inside surface and an outside surface of the back wall 730, and which is arranged so that one part overlaps with the protrusion part 450 in a width direction; a first interposition member which is filled or sealed in the protrusion part 450, and which adheres, fastens or fixes the inner box 750 and the vacuum heat insulation material 400; a second interposition member which adheres, fastens or fixes the vacuum heat insulation material 400 and an outer box 710; and injection ports 703, 704 which are provided on the back wall 730 and which inject an undiluted solution of the first interposition member. The injection ports 703, 704 are provided in a range in which the protrusion part 450 is provided. The vacuum heat insulation material 400 is arranged so as not to block at least one part of the injection ports 703, 704, and it is formed integrally with the inner box and the outer box in the protrusion part 450.SELECTED DRAWING: Figure 4
