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 has an illuminated trim assembly that includes an appliance cabinet having first and second sidewalls and a top wall. The appliance cabinet defines a compartment. A trim breaker member extends along a forward edge of the first and second sidewalls and the top wall. A light housing is positioned rearward of the trim breaker member and defines a light source channel. The light source channel has an open end proximate the compartment. A lens extends between the trim breaker member and the light housing. The lens is positioned to separate the light source channel from the compartment. A light source is positioned within the light source channel and is configured to direct light through the lens into the compartment.

Abstract: A refrigerating appliance includes a cabinet having an inner liner, an outer wrapper and a plastic trim breaker extending therebetween. A door panel is operable relative to the cabinet between open and closed positions. The door panel has a seal that magnetically engages a contact surface of the cabinet to define the closed position of the door panel. A ferromagnetic plate extends over a portion of the plastic trim breaker to define the contact surface. A heat loop is disposed between the trim breaker and the ferromagnetic plate, in thermal communication with the contact surface. The heat loop extends from the trim breaker to a machine compartment of the cabinet. The ferromagnetic plate includes a looped edge that defines a heating chase. The heat loop is positioned within the heating chase and extends to the machine compartment.

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 refrigerator includes a wrapper having an opening with a front edge. A liner includes an opening and a front edge. A thermal bridge interconnects the wrapper and the liner to form a vacuum insulated cavity therebetween. The thermal bridge includes an outwardly opening channel and first and second inwardly opening channels. The front edge of wrapper is received in the first inwardly opening channel, and the front edge of the liner is received in the second inwardly opening channel. The second inwardly opening channel is inset relative to the first inwardly opening channel on the thermal bridge. A conduit is disposed within the outwardly opening channel and is configured to circulate a heated medium. The wrapper and liner are contemplated to be comprised of conductive materials, such sheet metal, while the thermal bridge is comprised of a thermally resistant material, such as a polymeric material.

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.
