Abstract: A refrigerator includes a vacuum-insulated cabinet structure enclosing an insulating cavity and including an outer wrapper having a first side wall defining a perimeter, an outer frame portion defined radially inward of the perimeter, and an inner area surrounded and supported by the outer frame portion. The inner area initially defines a first planar level with at least a portion of the outer frame portion extending to a second planar level parallel to and spaced apart from the first planar level in an axially outward direction. The insulating cavity is sealed and has a vacuum drawn therefrom with the outer frame portion deformed such that the inner area is moved axially inward away from the second planar level under a force of the vacuum within the insulating cavity with at least the portion of the outer frame portion remaining at the second planar level.

Abstract: A refrigerator including an inner case, an outer case, and a vacuum space provided between the inner case and the outer case to insulate the inner case from the outer case. The inner case defines an exterior appearance of a storage space, with a communication hole formed therein. The outer case is spaced apart a predetermined distance from the inner case, and a communication is formed at a position corresponding to the communication hole of the inner case. A connection pipe passes through the vacuum space to connect the communication hole of the inner case and the communication hole of the outer case with each other.

Abstract: A refrigerator includes an inner case, an outer case, a vacuum space, and a liquid-gas interchanger. The inner case defines an exterior appearance of a storage space. The outer case is spaced apart a predetermined distance from the inner case. The vacuum space is provided between the inner case and the outer case, and maintains a vacuum to insulate the inner case from the outer case. The liquid-gas interchanger is arranged in the vacuum space to generate heat exchange between a refrigerant after it is exhausted from an evaporator and a refrigerant before it is drawn into an evaporator.

Abstract: A method for forming a super-insulating material for a vacuum insulated structure for an appliance includes disposing hollow glass spheres within a rotating drum, wherein a plurality of interstitial spaces are defined between the hollow glass spheres. An anchor material is disposed within the rotating drum. The hollow glass spheres and the anchor material are rotated within the rotating drum, wherein the anchor material is mixed with the hollow glass spheres to partially occupy the interstitial spaces. A silica-based material is disposed within the rotating drum. The silica-based material is mixed with the anchor material and the hollow glass spheres to define a super-insulating material, wherein the silica-based material attaches to the anchor material and is entrapped within the interstitial spaces. The silica-based material and the anchor material occupy substantially all of an interstitial volume defined by the interstitial spaces.
