Abstract: An appliance includes an outer wrapper, an inner liner, a trim breaker having a wrapper channel that receives a wrapper edge of the outer wrapper and a liner channel that receives a liner edge of the inner liner, and an insulation material disposed within an insulating cavity defined therebetween. A multi-component thermal encapsulation material defines pre-mix, application and sealing states. The pre-mix state is defined by the distinct components of the thermal encapsulation material being separated from one another, the application state defined by the distinct components combined together into an uncured state of the thermal encapsulation material, and the sealing state defined by the thermal encapsulation material disposed within the wrapper and liner channels and surrounding the wrapper and liner edges, respectively, in the sealing state that defines a hermetic seal between the trim breaker and the outer wrapper and the inner liner.

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 making a cabinet for refrigerators and the like. The method includes forming a liner and a wrapper. The method further includes providing a vacuum insulated core that includes a filler material disposed inside a substantially impermeable envelope that is evacuated to form a vacuum inside of the envelope. The vacuum insulated core includes a first wall and a second wall extending transversely relative to the first wall. The core is adhesively secured to the wrapper, and the liner is adhesively secured to the core. The wrapper and the liner are sealed together at the peripheries thereof.

Abstract: A method of routing utility lines in a vacuum insulated refrigerator structure includes forming a shell and an elongated umbilical comprising an elongated impervious sleeve and a core structure defining at least two elongated internal passageways extending lengthwise along the umbilical. The method includes sealingly connecting a first end of the sleeve to the shell at a first opening, and sealingly connecting a second end of the sleeve to the shell at a second opening. A vacuum is formed in an internal cavity of the shell. Utility lines are routed through at least one of the elongated internal passageways whereby portions of the utility lines are disposed inside the umbilical, and opposite ends of the utility lines extend out of the opposite ends of the umbilical.

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 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.
