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.

Abstract: A refrigerator includes a wall covering assembly having a top wall spaced-apart from a top wall of a liner, and a rear wall spaced-apart from a rear wall of the liner. The wall covering assembly includes a pattern of ports for providing outwardly directed cooled air to the refrigerator cabinet from a duct assembly. The duct assembly is configured to deliver cooled air through the ventilated portion of the wall covering assembly and also deliver cooled air to a front portion of the refrigerator cabinet via a downwardly directed air curtain. The air curtain disrupts the outward flow of air from the ventilated portion of the wall covering assembly before the cooled air reaches a gasket assembly disposed around the refrigerator doors. Angled venting slots disposed on the wall covering assembly direct air towards inner surfaces of the doors without disruption from the air curtain.

Abstract: An insulated structure includes a wrapper that defines a first aperture. A liner defines a second aperture and is coupled to the wrapper. A negative pressure is maintained between the wrapper and the liner. A drainage assembly extends between the liner and the wrapper and is disposed within the first aperture and the second aperture. The drainage assembly includes a flexible body that has a plurality of flexures, first and second surfaces, and an opening that is defined between the first and second surfaces. The flexible body has at least one notch that is defined on the first surface that extends from a portion of the opening. A drainage tube extends through the opening that is defined by the flexible body and is operably coupled to the flexible body. The drainage tube includes at least one flange disposed within the at least one notch of the flexible body.

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 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.
