Abstract: A vacuum insulated structure includes a first cover member of a stamped unitary sheet defining a perimeter portion positioned at a first planar level and a reinforcing member formed in the interior sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion. The vacuum insulated structure also includes a second cover member and a thermal bridge interconnecting the first cover member and the second cover member at the perimeter portions thereof to define an insulating cavity therebetween. The insulating cavity is a sealed cavity having a vacuum drawn therefrom, and the first reinforcing member is configured to reduce deformation of the first cover member in at least an area adjacent the reinforcing member and to define a portion of a path for air flow out of the sealed cavity during a vacuum draw process.

Abstract: A vacuum insulated structure includes a first panel having an inner surface defining an area. The first panel includes a vacuum port. A trim breaker interconnects the first panel with a second panel in an air-tight manner to define a vacuum cavity therebetween. A first filter member is disposed on and substantially covers the area of the inner surface of the first panel and the vacuum port of the first panel. A second filter member substantially covers the first filter member to define a channel therebetween. The channel includes an area commensurate with the area of the inner surface of the first panel. The first panel may also include a mesh member covered by a filter member to define a channel therebetween to improve evacuation time using the channel to evacuate the vacuum cavity.

Abstract: A method for assembling a vacuum insulation assembly for an appliance is provided. The method includes steps of defining a plurality of spaces on a guide and positioning the guide flush with an inner surface of a panel. The method further includes a step of determining positions of a plurality of clips using the plurality of spaces of the guide. Another step of the method includes coupling the plurality of clips with the inner surface of the panel. The method also includes separating the guide from the panel and coupling permeable tubing with the plurality of clips.

Abstract: A vacuum insulated structure includes a first panel and a second panel, wherein the second panel is operably coupled to the first panel to define an insulating space therebetween. An airway system is disposed within the insulating space and includes portions of porous tubing configured to draw air along lengths of the porous tubing from the insulating space during an evacuation procedure. A plurality of connectors interconnect the portions of porous tubing of the airway system to inner walls of the insulating space. The connectors may include support members that extend between the panels within the insulating space to support the vacuum insulated structure under vacuum pressure. Further, first and second panels can include rigidifying structural configurations to combat vacuum bowing during the evacuation procedure.

Abstract: A vacuum insulation assembly is provided. The vacuum insulation assembly includes a panel assembly. The panel assembly includes a front panel and a rear panel. The front panel and the rear panel define a cavity. An aperture is defined by the rear panel. A vacuum port is positioned within the aperture and is selectively couplable with a vacuum device. A plurality of clips are operably coupled with an inner surface of the rear panel. Each of the plurality of clips defines a channel. Tubing is positioned within the channel of each of the plurality of clips. The tubing has a first end and a second end. The first and second ends are coupled with the vacuum port.

Abstract: A vacuum insulated refrigerator structure includes a shell having a liner and a wrapper where the shell defines an internal vacuum cavity, and a refrigerator and/or freezer compartment. The vacuum insulated refrigerator structure additionally includes an elongated pass-through defining an elongated internal space having a central portion disposed in the internal vacuum cavity. The elongated pass-through has opposite end portions that are sealingly connected to the shell, each opposite end portion having an opening that permits access to the elongated internal space from the outside of the shell. The vacuum insulated refrigerator structure also includes a vacuum core material fill positioned in the internal vacuum cavity and one or more utility lines disposed in one or more elongated internal passageways extending out of the openings at the opposite end portions of the elongated pass-through.
