Abstract: A vacuum insulated appliance structure, comprising: a first layer of a first polymer material. A second layer of a second polymer material is molded to (e.g. over) at least a portion of the first layer, and a third layer of a third polymer material is molded to (e.g. over) at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. One or more additional components are secured to the first component to form a vacuum cavity. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum.

Abstract: A method for manufacturing an insulation member for a vacuum insulated structure includes the steps of forming a bag that has an opening using a single layer porous fabric, filling the bag with insulation materials via the opening, sealing the opening of the bag, and vibrating the bag to evenly distribute, de-aerate, and densify the insulation material to form a pillow. The method further includes the steps of compressing the pillow within a mold to define a compressed insulation member, and evacuating the compressed insulation member within an insulated structure to define a vacuum insulated structure.

Abstract: An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.

Abstract: A method for manufacturing a vacuum insulated structure includes adhering a trim breaker to a wrapper and a liner via an adhesive to define an insulated structure. The insulated structure is positioned within an evacuation chamber proximate to a first heater and a second heater. The insulated structure and the evacuation chamber are heated via the first heater and the second heater. The evacuation chamber is evacuated via a first vacuum pump, and the insulated structure is evacuated via a second vacuum pump.

Abstract: An appliance includes an outer wrapper having a plurality of joined walls that define a plurality of vertices and edges. An inner liner is sealed with the outer wrapper to define an insulation space. A vacuum port is disposed on an external surface of the outer wrapper. A channel is in fluid communication with the vacuum port and extends along at least one edge defined by first and second walls of the outer wrapper. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed along the channel such that air can be drawn from the insulation space past the filter media, into the channel, and through each vacuum port.

Abstract: An outer wrapper that defines a top wall, a bottom wall, a rear wall, and first and second side walls and includes an inner liner. A trim breaker seals the outer wrapper to the inner liner to define an insulation space. A single vacuum port is disposed on each of the top wall, the bottom wall, and the first and second side walls. A plurality of vacuum ports is disposed on the rear wall. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed proximate each vacuum port such that air can be drawn from the insulation space past the filter media and through each vacuum port.
