Heat-insulating cabinet and refrigerator including the heat-insulating cabinet

摘要

A heat insulating box (8) is provided with: an inner box (10); outer box (9); and vacuum heat insulating materials (1) and a foamed heat insulating material (11), which are filled into the space between the inner box (10) and the outer box (9). A portion of the lower part of the heat insulating box (8) is recessed inward to form a machine compartment (13) in which a compressor (31) is disposed. A single bent vacuum heat insulating material (1) is disposed so as to extend from the bottom (15) of the heat insulating box (8) to the upright wall (14) of the machine compartment (13), the upright wall (14) being raised from the bottom (15). A protrusion (16a) which protrudes to the inner box (10) side is formed on the outer box (9) in the area thereof which constitutes at least the upright wall (14). The vacuum heat insulating material (1) which is provided so as to extend from the bottom (15) to the upright wall (14) is provided so as to be in contact with the protrusion (16a) and is disposed within the upright wall (14) so as to be away a predetermined distance from the outer box (9) excluding the protrusion (16a).
