Abstract: An appliance includes an outer wrapper having a plurality of joined walls that define a plurality of vertices and edges. An inner liner is sealed with the outer wrapper to define an insulation space. A vacuum port is disposed on an external surface of the outer wrapper. A channel is in fluid communication with the vacuum port and extends along at least one edge defined by first and second walls of the outer wrapper. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed along the channel such that air can be drawn from the insulation space past the filter media, into the channel, and through each vacuum port.

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: 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: 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.

Abstract: 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.

Abstract: A refrigerator comprising: a cabinet; a door operably connected to the cabinet, the door having a closed position relative to the cabinet and an opened position relative to the cabinet, and the door transitions from the closed position to the opened position in a non-circular path; a liquid outlet disposed at the cabinet; and a liquid receiver disposed at the door, the liquid receiver configured to receive liquid exiting the liquid outlet when the door is in the closed position but not in the opened position. The refrigerator can further include a gasket adjacent to the liquid receiver and a gasket adjacent to the liquid outlet. When the door is in the closed position, the gasket of the door can cooperate with the gasket of the cabinet to form a sealed channel to seal liquid transfer from the liquid outlet to the liquid receiver for use at the door.

Abstract: A method of forming a refrigerator cabinet includes a step where an external wrapper that defines a rear surface is provided. The rear surface of the external wrapper is deep-drawn to form a machine compartment that defines a top wall, a bottom wall, and an interior wall. An inner liner is positioned within the external wrapper such that a gap is defined between the inner liner and the interior wall of the machine compartment. A vacuum is drawn within the gap.
