Abstract: A method for manufacturing an insulation member for a vacuum insulated structure includes the steps of forming a bag that has an opening using a single layer porous fabric, filling the bag with insulation materials via the opening, sealing the opening of the bag, and vibrating the bag to evenly distribute, de-aerate, and densify the insulation material to form a pillow. The method further includes the steps of compressing the pillow within a mold to define a compressed insulation member, and evacuating the compressed insulation member within an insulated structure to define a vacuum insulated structure.

Abstract: A method of forming an insulated door panel includes folding side flanges of a metallic sheet to define side edges of a structural outer panel that extend from a front panel. A gap is defined between each set of adjacent side edges. Interior blocks are secured to an interior of the structural outer panel proximate each gap to define adhesive cavities. Exterior blocks are positioned at an exterior surface of the structural outer panel at each gap to further define the adhesive cavities. An adhesive is disposed within each adhesive cavity and is contained therein by the interior and exterior blocks. The adhesive is cured to a solid sealing member that adheres the interior blocks to the interior surface of the structural outer panel to form a sealed structural panel. The exterior blocks are removed and each solid sealing member defines a hermetic seal at each gap.

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: An outer wrapper that defines a top wall, a bottom wall, a rear wall, and first and second side walls and includes an inner liner. A trim breaker seals the outer wrapper to the inner liner to define an insulation space. A single vacuum port is disposed on each of the top wall, the bottom wall, and the first and second side walls. A plurality of vacuum ports is disposed on the rear wall. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed proximate each vacuum port such that air can be drawn from the insulation space past the filter media and through each vacuum port.

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 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.
