An insulation compaction device includes an insulating structure of an appliance and has an insulating media disposed within an insulating cavity. An operable piston selectively engages the insulating structure and operates to define a selected cavity volume of the insulating cavity and a selected insulation density of the insulating media. A valve is attached to the insulating structure and in a passive state releases gas from the insulating cavity to the exterior during operation of the operable piston. Selective operation of a pump mechanism places the valve in an active state to extract gas from the insulating cavity and define a cavity pressure of the insulating cavity that is less than an equalized pressure. The operable piston and the pump mechanism are at least one of sequentially and simultaneously operable to define a selected piston chamber environment defined by the selected cavity volume and the cavity pressure.

Insulation compaction device and method for forming an insulated structure for an appliance

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.

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.

Method for forming a vacuum insulated structure

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.

An operable panel for an appliance includes a metallic outer wrapper having a perimetrical wrapper edge that partially defines a perimetrical breaker channel, an inner liner and a plurality of corner brackets disposed proximate the perimetrical wrapper edge. Each corner bracket cooperates with the perimetrical wrapper edge to fully define the perimetrical breaker channel. A trim breaker is adhered to the metallic outer wrapper and the corner brackets at the perimetrical breaker channel and having a liner channel that receives a portion of the inner liner. The trim breaker extends between the inner liner and the outer wrapper. An insulation material is disposed within an insulating cavity defined between the inner liner and the outer wrapper.

Structural panel for an appliance having stamped components and method therefor

A vacuum insulated cabinet structure includes first and second cover members having pre-deformed portions and perimeter portions. The perimeter portions of the first and second cover members are disposed along first and second planar levels and the pre-deformed portions of the first and second cover members include portions thereof extending outwardly relative to the first and second planar levels. A thermal bridge interconnects 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. The pre-deformed portions of the first and second cover members move inwardly towards the first and second planar levels under a force of the vacuum within the insulating cavity.

An insulated structural cabinet for an appliance includes outer walls that are attached together to define a structural envelope that is operable from an expanded state that includes an expanded interior volume of the interior cavity, to a final state that includes a contracted interior volume of the interior cavity, wherein the contracted interior volume is less than the expanded interior volume. An insulating material disposed throughout the interior cavity in the expanded state. Operation of the structural envelope to the final state densifies the insulating material. Operation of the structural envelope to the final state is performed by a vacuum pump that expresses air from the interior cavity. The structural envelope is also operable from a performed state to the expanded state via an expanding device, and subsequently operable from the expanded state to the final state.

Insulated structural cabinet for an appliance

An appliance is provided herein. The appliance includes a cabinet having a wrapper, a liner, and a trim breaker. The wrapper, the liner, and the trim breaker define an insulating cavity therebetween. An insulating material is disposed within the insulating cavity. A frame includes an upper frame portion, a vertical frame portion, and a lower frame portion. The lower portion includes a top section, a bottom section, an inner section, and a front section. A door is rotationally mounted to the cabinet via an upper hinge and a lower hinge mounted to the frame.
