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: An appliance includes a metallic outer wrapper having sidewalls, a wrapper backwall and a machine wall. At least one metallic inner liner has liner walls and a liner backwall, wherein the metallic outer wrapper and the at least one metallic inner liner are coupled together at a trim breaker to define a structural cabinet having a hermetically sealed interior cavity defined between the metallic outer wrapper and the at least one metallic inner liner. The trim breaker defines a front face of the structural cabinet. At least one trim breaker conduit extends through the wrapper and liner backwalls wherein the trim breaker conduit defines a conduit through the structural cabinet, and wherein the structural cabinet is hermetically sealed at the trim breaker conduit.
