Abstract: An operable panel for an appliance includes a metallic outer wrapper having a perimetrical wrapper edge that partially defines a perimetrical breaker channel, an inner liner and a plurality of corner brackets disposed proximate the perimetrical wrapper edge. Each corner bracket cooperates with the perimetrical wrapper edge to fully define the perimetrical breaker channel. A trim breaker is adhered to the metallic outer wrapper and the corner brackets at the perimetrical breaker channel and having a liner channel that receives a portion of the inner liner. The trim breaker extends between the inner liner and the outer wrapper. An insulation material is disposed within an insulating cavity defined between the inner liner and the outer wrapper.

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.

Abstract: An insulation structure for an appliance includes a cabinet having an outer wrapper and an inner liner, with an insulating cavity defined therebetween. Insulating powder material is disposed substantially throughout the insulating cavity. An insulating gas is disposed within the insulating cavity, wherein the insulating powder material is combined with the insulating gas and cooperatively defines a suspended state and a precipitated state. The suspended state is defined by the insulating gas in motion and the insulating powder being in an aeolian suspension within the insulating gas while in motion. The precipitated state is defined by the insulating gas being in a deposition state and the insulating powder being precipitated from the insulating gas and deposited within the insulating cavity.

Abstract: A vacuum insulated refrigerator structure includes an outer wrapper having a first opening and a first edge extending around the first opening. A liner has a second opening and second edge extending around the second opening. The liner is disposed inside the wrapper with the first and second edges being spaced apart to form a gap therebetween. An insulating thermal bridge extends across the gap, and an airtight vacuum cavity is formed between the wrapper and the liner. The thermal bridge includes elongated first and second channels having sealant disposed therein, and the first and second edges are disposed in the first and second channels, respectively. Porous core material may be disposed in the vacuum cavity.

Abstract: An insulation system for an appliance includes a first vacuum insulated structure having a first set of sidewalls that define a first refrigerating compartment, a second vacuum insulated structure having a second set of sidewalls that define a second refrigerating compartment and a medial insulation structure having a rigid perimeter wall. The rigid perimeter wall includes a front portion that defines at least one hinge support adapted to support an appliance door. The rigid perimeter wall defines an insulating cavity that is filled with an insulating material. The first vacuum insulated structure engages a first edge of the perimeter wall and the second vacuum insulated structure engages a second edge of the perimeter wall.

Abstract: A vacuum insulated cabinet structure includes an exterior wrapper with a front edge extending around an opening thereof. At least one liner includes a front edge extending around an opening of the liner, wherein the liner is disposed inside of the wrapper with the front edge of the wrapper disposed around the front edge of the liner in assembly. A thermal bridge includes an outer coupling portion and an inner coupling portion. In assembly, the outer coupling portion is overmolded to a portion of the front edge of the wrapper, and the inner coupling portion is overmolded to a portion of the front edge of the liner to form a sealed vacuum cavity between the wrapper and the liner. The thermal bridge is formed in a mold in which the preformed wrapper and liner are partially disposed to form a unitary composite structure.
