Abstract: An appliance includes an outer wrapper and an inner liner placed within the outer wrapper and spaced apart from the outer wrapper to define an insulating space. A trim breaker extends between the inner liner and the outer wrapper to define a structural cabinet. The trim breaker defines a front face of the cabinet. The trim breaker defines a gas conduit disposed within a wall of the structural cabinet proximate the insulating space. The gas conduit is adapted to define selective communication between the insulating space and an exterior of the structural cabinet. An insulating material is disposed within the insulating space, wherein the gas conduit is substantially free of the insulating material.

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: An insulation delivery apparatus for forming an insulated appliance structure includes an insulated structure having a wrapper and a liner that define an interior cavity and a hopper having a storage bin and a delivery mechanism. The delivery mechanism delivers an insulating medium from the storage bin, through an insulation conduit and into the interior cavity. The delivery mechanism operates between idle and delivery states. A pressing mechanism is coupled with the insulation conduit and is in selective engagement with the insulated structure. The pressing mechanism operates between rest and compressing states. An inner support is in selective engagement with an outer surface of the inner liner and an operable outer support in selective engagement with the outer wrapper. The inner support and the operable outer support provide structural support to the insulated structure when the pressing mechanism is in the compressing state.

Abstract: A method of forming a refrigerator cabinet includes a step where an external wrapper that defines a rear surface is provided. The rear surface of the external wrapper is deep-drawn to form a machine compartment that defines a top wall, a bottom wall, and an interior wall. An inner liner is positioned within the external wrapper such that a gap is defined between the inner liner and the interior wall of the machine compartment. A vacuum is drawn within the gap.

Abstract: A method of forming a vacuum insulated structure includes providing a structural envelope an insulating cavity defined within the structural envelope. An expanding device is attached to opposing outer walls of the structural envelope and the interior cavity is expanded by pulling the opposing outer walls away from one another to define an expanded state. An insulating material is disposed within the insulating cavity to occupy substantially all of the insulating cavity in the expanded state. Gas is expressed from the insulating cavity to collapse the structural envelope to a final state and a final interior volume that is less than the expanded interior volume. The final state of the structural envelope defines a densified state of the insulating material within the insulating cavity. The vacuum port is then closed to hermetically seal the insulating cavity.

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.
