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: 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.

Abstract: A method for forming a vacuum insulated structure using a prepared core material includes preparing a powder insulation material defining a bulk density, pre-densifying the powder insulation material to form a pre-densified insulation base, crushing the pre-densified insulation base into granular core insulation to define a core density of the granular core insulation, disposing the granular core insulation having the core density into an insulating cavity defined within an insulating structure and expressing gas from the interior cavity of the insulating structure to further densify the granular core insulation to define a target density. The granular core insulation defines the target density disposed within the insulating structure defines the vacuum insulation structure, wherein the target density defines a density in the range of from approximately 80 grams per liter to approximately 350 grams per liter.

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.
