摘要： A method of forming a vacuum insulated refrigerator cabinet structure includes providing a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer structural layers. The barrier material and the first and second outer layers comprise thermoplastic polymers. The multi-layer sheet of material is thermoformed to form a non-planar first component having a central portion and four sidewalls extending transversely from the central portion. The method further includes securing a second component having a central portion and four sidewalls extending transversely from the central portion to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space. The first and second components are sealed together to form a vacuum insulated refrigerator cabinet structure.

摘要： A method of forming a vacuum insulated structure includes providing a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers. The multi-layer sheet of material is thermoformed to form a non-planar first component. The first component is at least partially coated utilizing a plasma polymerization process or a physical vapor deposition process to improve the barrier properties of the first component. The method further includes securing a second component to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space.

摘要： 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.

摘要： A vacuum insulated structure includes a multi-layer sheet of material comprising at least one layer of barrier material that is disposed between first and second outer layers. The barrier material and the first and second outer layers comprise thermoplastic polymers or elastomeric or hybrid material systems. The multi-layer sheet of material is thermoformed or vacuum formed to form a non-planar first component having a central portion and four sidewalls extending transversely from the central portion. A second component having a central portion and four sidewalls extending transversely from the central portion is secured to the first component to form an interior space therebetween. Porous filler material is positioned in the interior space, and a vacuum is formed in the interior space by removing gasses and moisture (water vapor). The first and second components are sealed together to form a vacuum insulated structure.

摘要： A method of fabricating a vacuum insulated refrigerator structure includes injection molding a first layer of a first polymer material. A second layer of a second polymer material is injection molded over at least a portion of the first layer, and a third layer of a third polymer material is injection molded over at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. A second component is secured to the first component to form a vacuum cavity therebetween. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum. At least one of the first and third layers includes a structural reinforcement such as a rib or screw boss of increased thickness that is formed during the injection molding process.

摘要： A vacuum insulated appliance structure, comprising: a first layer of a first polymer material. A second layer of a second polymer material is molded to (e.g. over) at least a portion of the first layer, and a third layer of a third polymer material is molded to (e.g. over) at least a portion of the second layer to form a first component. At least one of the layers is impervious to one or more gasses. One or more additional components are secured to the first component to form a vacuum cavity. The vacuum cavity is filled with a porous material, and the vacuum cavity is evacuated to form a vacuum.
