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: An appliance includes a panel having a raised landing outwardly extending from a first surface of the panel. A vacuum port is disposed on the raised landing. A system of channels is disposed over the first surface of the panel and outwardly extends therefrom. The system of channels substantially covers the first surface of the panel. The first surface of the panel is covered with a filter member that covers the system of channels. The raised landing, and vacuum port thereof, is fluidically coupled to the system of channels at multiple connecting locations.

Abstract: A method of measuring pressure includes the steps of (1) providing a vacuum cabinet with a storage compartment and an insulating space, and three temperature sensors; (2) sensing a first temperature level of an interior wall of the storage compartment; (3) sensing an ambient temperature level within the storage compartment; (4) sensing a second temperature level of an exterior wall of the storage compartment; (5) calculating an overall heat transfer coefficient (Q) using the ambient temperature level, the first temperature level, and a convective heat transfer coefficient for the interior wall of the storage compartment; (6) calculating a temperature differential between the second and first temperature levels; (7) determining a conductivity level (K) using the temperature differential, the overall heat transfer coefficient (Q) and a thickness of the insulating space; and (8) determining a pressure level (P) within the insulating space using the conductivity level (K).

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 door assembly for an appliance includes a wrapper operably coupled with a liner to define an insulation cavity therebetween. An attachment assembly operably couples to the liner and defines a slot. A storage assembly couples with the attachment assembly. The storage assembly includes a bin. The storage assembly further includes a bracket operably coupling the bin to the attachment assembly via a retention feature. The bracket includes a support member defining a groove extending between ends of the bracket. The storage assembly further includes a rim extending from the bin and engaging the groove to secure the bin to the bracket.

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.
