Refrigerator with vacuum space

A refrigerator comprising:

• an inner case that defines a storage space and that is made of metal, an inside surface of the inner case being exposed to the storage space;
• an outer case that houses the inner case, that is made of metal, and that defines a predetermined gap between an inside surface of the outer case and an outer surface of the inner case, wherein the inner case and the outer case define a vacuum space that is disposed between the inner case and the outer case and that is configured to insulate the outer case from the inner case;
• a supporting portion disposed in the vacuum space and configured to space the outer case from the inner case, the supporting portion being disposed between the inside surface of the outer case and the outside surface of the inner case and extending 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 cover member disposed on the outer case;
• and
• a heat spreading plate on the inside surface of the outer case and configured to control a temperature of the outer case, the heat spreading plate being located adjacent to the supporting portion to reduce dew forming at the outer case by suppressing a surface temperature drop of the outer case caused by heat conduction from the inner case to the outer case through the supporting portion,
• wherein the heat spreading plate is arranged adjacent to a place at which the supporting portion is mounted, and is configured to spread cold from a contact point of the supporting portion of the outer case to a place adjacent to the contact point after the cold is transmitted to the outer case from the inner case through the supporting portion,
• wherein the refrigerator further comprises:
• a plurality of supporting portions that are each disposed between 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 being one of the plurality of supporting portions,
• wherein the supporting portions are configured to conduct heat between the inner case and the outer case through the vacuum space, and
• wherein the cover member is located on the heat spreading plate that covers the supporting portion, an area of the heating spreading plate being larger than a sectional area of the supporting portion.

• wherein each of the supporting portions has a shape corresponding to a boss or a column that protrudes from the outside surface of the inner case to the inside surface of the outer case or that protrudes from the inside surface of the outer case to the outside surface of the inner case,
• wherein the supporting portions do not laterally contact with each other,
• wherein the supporting portions are configured to conduct heat between the inner case and the outer case through the vacuum space, and
• wherein the heat spreading plate covers a part of the outer case, the area of the heating spreading plate being smaller than an area of the outer case.
