Abstract: 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.

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 method of forming a vacuum insulated structure includes providing a structural envelope an insulating cavity defined within the structural envelope. An expanding device is attached to opposing outer walls of the structural envelope and the interior cavity is expanded by pulling the opposing outer walls away from one another to define an expanded state. An insulating material is disposed within the insulating cavity to occupy substantially all of the insulating cavity in the expanded state. Gas is expressed from the insulating cavity to collapse the structural envelope to a final state and a final interior volume that is less than the expanded interior volume. The final state of the structural envelope defines a densified state of the insulating material within the insulating cavity. The vacuum port is then closed to hermetically seal the insulating cavity.

Abstract: A refrigeration unit includes a cabinet, a door coupled to the cabinet, at least one gasket coupled to the door, and a heat loop conduit. The cabinet includes a front perimeter that surrounds an opening to a storage compartment within the cabinet. The door is operable between an open position to provide access to the storage compartment and a closed position to conceal the opening to the storage compartment. The at least one gasket is configured to be compressed between the door and the front perimeter of the cabinet in the closed position of the door. The heat loop conduit has a first conduit portion that extends around a majority of the opening along the front perimeter of the cabinet and a second conduit portion that extends around the majority of the opening along the front perimeter of the cabinet.

Abstract: A method of fabricating a vacuum insulated refrigerator structure includes positioning a first barrier film in a female mold cavity. Porous filler material is positioned on the barrier film, and a second barrier film is positioned over the porous filler material. A male mold is brought into contact with the second barrier film to deform and compress the porous filler material into a 3D shape. A vacuum is formed between the first and second barrier films, and the first and second peripheral edge portions are sealed together to form a vacuum insulated core. The vacuum insulated core may be positioned between a liner and a wrapper to form an insulated refrigerator cabinet, door, or other vacuum insulated component.

Abstract: A refrigerating appliance includes a cabinet assembly that defines an access opening for storing food goods. The cabinet assembly defines an insulating cavity that receives insulation. A mullion assembly extends across the access opening and a trim breaker extends about the access opening. The trim breaker includes a body portion that covers the insulating cavity. First and second connecting flanges extend outwardly from the body portion in a first direction and operably coupled to an inside wall and an outside wall of the cabinet assembly, such that the trim breaker seals the insulating cavity. A forward spacing flange extends outwardly from the body portion of the trim breaker in a second direction that is opposed to the first direction of the first and second connecting flanges. The forward spacing flange contacts the mullion assembly and at least partially defines a receiving space between the mullion assembly and the trim breaker.
