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 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: 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.
