Refrigerator comprising vacuum space

A home appliance or a vacuum wall, comprising:

• an inner case;
• an outer case spaced apart from the inner case, wherein the inner case and the outer case define a vacuum space disposed between the outer case and the inner case and configured to insulate the outer case from the inner case;
• a reinforcing member provided to at least one of a surface of the inner case or a surface of the outer case and configured to prevent the inner case and the outer case from being distorted by an external impact or being deformed during an evacuation process to form the vacuum space;
• and
• a getter provided to the vacuum space and configured to collect gas liable to present in the vacuum space, thereby preventing heat transfer caused by the gas liable to form by a chemical reaction of the outer case or the inner case,
• wherein the reinforcing member is projected from at least one of the surface of the inner case or the surface of the outer case.
