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： 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.

摘要： An insulation system for an appliance includes a first vacuum insulated structure having a first set of sidewalls that define a first refrigerating compartment, a second vacuum insulated structure having a second set of sidewalls that define a second refrigerating compartment and a medial insulation structure having a rigid perimeter wall. The rigid perimeter wall includes a front portion that defines at least one hinge support adapted to support an appliance door. The rigid perimeter wall defines an insulating cavity that is filled with an insulating material. The first vacuum insulated structure engages a first edge of the perimeter wall and the second vacuum insulated structure engages a second edge of the perimeter wall.

摘要： 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.

摘要： 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.
