摘要： An appliance includes an outer wrapper, an inner liner, a trim breaker having a wrapper channel that receives a wrapper edge of the outer wrapper and a liner channel that receives a liner edge of the inner liner, and an insulation material disposed within an insulating cavity defined therebetween. A multi-component thermal encapsulation material defines pre-mix, application and sealing states. The pre-mix state is defined by the distinct components of the thermal encapsulation material being separated from one another, the application state defined by the distinct components combined together into an uncured state of the thermal encapsulation material, and the sealing state defined by the thermal encapsulation material disposed within the wrapper and liner channels and surrounding the wrapper and liner edges, respectively, in the sealing state that defines a hermetic seal between the trim breaker and the outer wrapper and the inner liner.

摘要： A method for forming a super-insulating material for a vacuum insulated structure includes disposing glass spheres within a rotating drum. A plurality of interstitial spaces are defined between the glass spheres. A binder material is disposed within the rotating drum. The glass spheres and the at least one binder material are rotated within the rotating drum, wherein the binder material is mixed during a first mixing stage with the glass spheres. A first insulating material is disposed within the rotating drum. The binder material, the first insulating material and the glass spheres are mixed to define an insulating base. A second insulating material is disposed within the rotating drum. The secondary insulating material is mixed with the insulating base to define a homogenous form of the super-insulating material, wherein the first and second insulating materials occupy substantially all of the interstitial spaces.

摘要： 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.

摘要： 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.

摘要： An insulation system for an appliance includes a first vacuum insulated structure having a first set of sidewalls that define a first refrigerating compartment, a second vacuum insulated structure having a second set of sidewalls that define a second refrigerating compartment and a medial insulation structure having a rigid perimeter wall. The rigid perimeter wall includes a front portion that defines at least one hinge support adapted to support an appliance door. The rigid perimeter wall defines an insulating cavity that is filled with an insulating material. The first vacuum insulated structure engages a first edge of the perimeter wall and the second vacuum insulated structure engages a second edge of the perimeter wall.
