Abstract: A door panel includes an outer panel having a generally planar body portion with inner and outer surfaces and a sidewall with a front edge. An inner panel includes a generally planar body portion with inner and outer surfaces and a sidewall with a front edge. A trim breaker interconnects the outer panel and the inner panel to form a vacuum cavity therebetween. The trim breaker includes first and second upright members interconnected by upper and lower cross members. The trim breaker further includes an inner channel and an outer channel spaced-apart from one another around the trim breaker. The outer channel is outwardly disposed around the inner channel. The front edge of the inner panel is received in the inner channel of the trim breaker, and the front edge of the outer panel is received in the outer channel of the trim breaker.

Abstract: An appliance includes an outer wrapper and an inner liner that form a structural cabinet having an insulating cavity defined between the inner liner and the outer wrapper. An elliptical insulation port is defined within the outer wrapper, wherein the elliptical insulation port is configured to allow passage of a cylindrical insulation conduit when the insulation conduit is positioned at an oblique angle relative to the structural cabinet. An insulation material is disposed within the insulating cavity. A sealing cap covers the elliptical insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity.

Abstract: An appliance includes a panel having a raised landing outwardly extending from a first surface of the panel. A vacuum port is disposed on the raised landing. A system of channels is disposed over the first surface of the panel and outwardly extends therefrom. The system of channels substantially covers the first surface of the panel. The first surface of the panel is covered with a filter member that covers the system of channels. The raised landing, and vacuum port thereof, is fluidically coupled to the system of channels at multiple connecting locations.

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 method of making a vacuum insulated refrigerator structure includes positioning a core of overlapping stacked sheets of fiberglass mat in an envelope of impermeable barrier material. The core is pressed into a predefined three dimensional shape by pressing first and second mold parts together. The core is evacuated, and the envelope is sealed to form a three dimensional core having an airtight envelope around the core. The three dimensional vacuum core is positioned between a wrapper and a liner, and the wrapper and the liner are interconnected to form a vacuum insulated refrigerator 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.
