  • Publication number: 20250091280
    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.

  • Patent number: 12188710
    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 appliance includes an outer wrapper and an inner liner that form a structural cabinet having an insulating cavity defined between the inner liner and the outer wrapper. An elliptical insulation port is defined within the outer wrapper, wherein the elliptical insulation port is configured to allow passage of a cylindrical insulation conduit when the insulation conduit is positioned at an oblique angle relative to the structural cabinet. An insulation material is disposed within the insulating cavity. A sealing cap covers the elliptical insulation port, wherein the sealing cap includes a protrusion that extends at least partially into the insulating cavity.

  • Publication number: 20240369290
    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.
