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 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 vacuum insulated appliance includes an outer wrapper and an inner liner. A ladder rack is coupled to the inner liner. The ladder rack includes first and second sidewalls coupled together by a connecting wall that defines a plurality of apertures. An adapter member includes a hook configured to extend through an aperture of the plurality of apertures when coupled to the ladder rack. The adapter member is coupled with a locking member that engages inner surface of first and second sidewalls of the ladder rack. A cantilever support is coupled to the adapter member and extends outward from the ladder rack. A rail assembly is coupled to an upper surface of the cantilever support. A spacer is coupled to an end of the cantilever support and abuts an inner liner surface. A storage feature is coupled to the rail assembly and is operable between stowed and deployed positions.

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: An appliance has an illuminated trim assembly that includes an appliance cabinet having first and second sidewalls and a top wall. The appliance cabinet defines a compartment. A trim breaker member extends along a forward edge of the first and second sidewalls and the top wall. A light housing is positioned rearward of the trim breaker member and defines a light source channel. The light source channel has an open end proximate the compartment. A lens extends between the trim breaker member and the light housing. The lens is positioned to separate the light source channel from the compartment. A light source is positioned within the light source channel and is configured to direct light through the lens into the compartment.

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 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.
