Patent ID: 7968160

Claim:
A refrigerator in combination with vacuum thermal insulation with inflatable load carrying structure comprising: two outer layers defining an evacuated space there between; at least one bulged layer including a plurality of inflatable cores arranged between the two outer layers to create an inflatable load carrying structure, wherein all of inflatable cores in the load carrying structure are spaced from each other, wherein all of the inflatable cores in the at least one bulged layer are substantially the same shape and size uniformly spaced from each other; a first valve for inserting pressurized air into the plurality of inflatable cores in the bulged layer; a second valve for evacuating an air from a space between the inflatable cores in the bulged layers to form a vacuum chamber; and wherein the second valve is openable to remove the air from the inflatable cores of the bulged layer to deflate the inflatable cores to enable a user to fold and transport the insulation; and the second valve being a vacuum valve for removing air remaining in the vacuum chamber, and wherein the vacuum thermal insulation has a mechanical strength safety factor of 1.3.
