  • Patent number: 10612834
    Abstract: A vacuum insulated refrigerator structure being formed from a wrapper extending around a liner is provided. The liner is positioned inside of the wrapper to form a gap there between, and to form a cavity between the wrapper and the liner. An insulating thermal bridge is formed from molding one or more extruded rails to one or more corner pieces in an injection molding device. The insulating thermal bridge is coupled across the gap wherein the insulating thermal bridge includes elongated first and second channels wherein the first and second edges are inserted into the elongated first and second channels, respectively. A curable sealant is contacted to the elongated first and second channels and the cavity is at least partially filled with a porous material between the wrapper and the liner. A vacuum is formed in the cavity and the cavity is sealed to maintain the vacuum.

  • Publication number: 20190331398
    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.

  • Publication number: 20190293338
    Abstract: A method of fabricating a refrigerator cabinet or door includes forming a wrapper and an inner liner. The method further includes forming a vacuum insulated core comprising a permeable core material that is disposed inside an impermeable envelope. A sheet of prefabricated compressible foam material is positioned between the vacuum insulated core between the inner door liner and/or the door wrapper. The prefabricated compressible foam material may be cut from a sheet of foam having substantially uniform thickness prior to fabrication of the refrigerator door. The foam compresses to accommodate differences in spacing between the vacuum insulated core and the door wrapper and/or the door liner.

  • Patent number: 10365030
    Abstract: A three-dimensional (3D) vacuum insulation panel (VIP) and a folding approach to create the 3D VIP from a two-dimensional (2D) VIP of non-uniform thickness for a refrigerator, a refrigerator freezer or a non-appliance, are disclosed. The folding approach includes placing a VIP main panel and a plurality of VIP wall panels on an outer film, where one or more panels are of a greater thickness than other VIP panels; placing an inner film on top of the VIP main and wall panels and sealing the films together. The inner film is longer than the outer film and this allows the films and the VIP wall panels to be folded into a finished panel, wherein the longer inner film allows for folding without causing tears or micro-cracks in the film that would adversely affect the insulation properties of the three-dimensional (3D) VIP.
