Abstract: 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.

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: A method for forming a super-insulating material for a vacuum insulated structure includes disposing glass spheres within a rotating drum. A plurality of interstitial spaces are defined between the glass spheres. A binder material is disposed within the rotating drum. The glass spheres and the at least one binder material are rotated within the rotating drum, wherein the binder material is mixed during a first mixing stage with the glass spheres. A first insulating material is disposed within the rotating drum. The binder material, the first insulating material and the glass spheres are mixed to define an insulating base. A second insulating material is disposed within the rotating drum. The secondary insulating material is mixed with the insulating base to define a homogenous form of the super-insulating material, wherein the first and second insulating materials occupy substantially all of the interstitial spaces.

Abstract: A vacuum insulated refrigerator structure includes an outer wrapper having a first opening and a first edge extending around the first opening. A liner has a second opening and second edge extending around the second opening. The liner is disposed inside the wrapper with the first and second edges being spaced apart to form a gap therebetween. An insulating thermal bridge extends across the gap, and an airtight vacuum cavity is formed between the wrapper and the liner. The thermal bridge includes elongated first and second channels having sealant disposed therein, and the first and second edges are disposed in the first and second channels, respectively. Porous core material may be disposed in the vacuum cavity.
