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 insulated door for an appliance includes an outer wrapper that defines an evacuation port. An inner liner is coupled to the outer wrapper defining an insulating cavity therebetween. A base is coupled to the outer wrapper adjacent to the evacuation port. A servicing tube has a connecting end and a servicing end. The servicing tube is in fluid communication with the insulating cavity via the evacuation port. The connecting end is coupled to the base. A handle has first and second ends coupled to the outer wrapper and a center portion therebetween spaced-apart from the outer wrapper. The first end is coupled to the outer wrapper proximate the evacuation port. The servicing tube extends along an inner surface of the handle.

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 vacuum insulated structure including a first cover member of a stamped unitary sheet defining a perimeter portion positioned at a first planar level and first rib formed in the unitary sheet extending to a second planar level spaced axially outward and disposed radially inward of the perimeter portion, a second cover member, and 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 rib defines a first portion of a path for air flow out of the sealed cavity during a vacuum draw process.
