Abstract:
1. A refrigerator comprising: a body having a storage space for storing a predetermined storage object, wherein the body includes; an inner case having the storage space, the inner case formed from metal, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, the outer case formed from metal, a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, a supporting portion provided to contact with the outside surface of the inner case and the inside surface of the outer case to maintain a spaced state of the vacuum space, the supporting portion formed from metal, wherein the supporting portion extends, through the vacuum space, from the outside surface of the inner case to the inside surface of the outer case or from the inside surface of the outer case to the outside surface of the inner case; a reinforcing rib provided to the outside surface of the inner case or the inside surface of the outer case for reinforcing strength thereof, the reinforcing rib being different than the supporting portion and being spaced apart from the supporting portion such that the reinforcing rib does not overlap with the supporting portion; a dewing preventive unit adjacent to the supporting portion for preventing dewing from taking place at the outer case by suppressing surface temperature drop of the outer case, which is caused by cold conducted from the inner case to the outer case through the supporting portion, the dewing preventive unit being located on the outside surface of the outer case at a location that is opposite to a portion of the inside surface of the outer case that the supporting portion contacts; a plurality of supporting portions that are each provided to contact with the outside surface of the inner case and the inside surface of the outer case to maintain the spaced state of the vacuum space, the supporting portion being one of the plurality of supporting portions; and a plurality of reinforcing ribs that are each provided to the outside surface of the inner case or the inside surface of the outer case for reinforcing strength thereof, the reinforcing rib being one of the plurality of reinforcing ribs, wherein the plurality of supporting portions and the plurality of reinforcing ribs are arranged spaced apart from each other such that the plurality of supporting portions and the plurality of reinforcing ribs do not overlap with each other, and wherein each of the plurality of supporting portions are located entirely within the vacuum space, each of the plurality of reinforcing ribs are located entirely within the vacuum space, and each of the plurality of reinforcing ribs have a length that is less than a width of the vacuum space such that each of the plurality of reinforcing ribs contacts one of the outside surface of the inner case and the inside surface of the outer case, but does not contact the other of the outside surface of the inner case and the inside surface of the outer case.
