Abstract: An insulated cabinet structure includes an inner liner having a plurality of walls defining a refrigerator compartment, and an external wrapper having a plurality of walls defining a refrigerator compartment receiving area. An insulation gap is formed between the walls of the inner liner and the walls of the external wrapper. A first insulation material is positioned on a wall of the external wrapper and extends outwardly into the insulation gap to partially fill the insulation gap. The first insulation material includes a renewable resource component having a particle size in a range from about 10 microns to about 25 microns. A second insulation material is disposed in the insulation gap, such that the first insulation material and the second insulation material together substantially fill the insulation gap.

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 vacuum insulated structure includes a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers or elastomeric or hybrid material systems. The multi-layer sheet of material is thermoformed or vacuum formed to form a non-planar first component having a central portion and four sidewalls extending transversely from the central portion. A second component having a central portion and four sidewalls extending transversely from the central portion is secured to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space by removing gasses and moisture (water vapor). The first and second components are sealed together to form a vacuum insulated structure.

Abstract: An insulation structure for an appliance includes a cabinet having an outer wrapper and an inner liner, with an insulating cavity defined therebetween. A plurality of hollow insulating organic/inorganic spheres is disposed within the insulating cavity, wherein a secondary insulating volume is defined between the plurality of hollow insulating organic/inorganic spheres and an interior surface of the cabinet. The interior surface of the cabinet defines the insulating cavity. An insulating fill material is disposed within the secondary insulating volume, wherein the insulating fill material and the plurality of hollow insulating organic/inorganic spheres define a substantially uniform insulating material.
