Abstract:
A vacuum insulated door structure includes a first wall having a first edge and a barrier layer, a second wall having a second barrier layer and a second edge coupled to the first wall member proximate the first perimetrical edge. The second wall includes at least four inner side walls and a back wall that defines a second wall offset. At least one tubular member extends between the first wall member and the second wall offset, wherein an inner conduit surface of the tubular member provides fluid communication between the first wall outer facing surface and the second wall outer facing surface. A cavity insulation material is disposed within a cavity volume defined between the first and second walls, wherein the cavity volume is hermetically sealed, and wherein the cavity volume includes an at least partial vacuum.
Abstract:
A method of forming a vacuum insulated refrigerator cabinet, the method comprising providing first and second sheets of material. The first sheet of material is thermoformed over a first forming tool forming a first intermediate structure. The first intermediate structure is then thermoformed over a second forming mold to create a second intermediate structure. The second sheet of material is then sealing connected with the second intermediate structure forming an annular space. A vacuum is created in the annular space creating a vacuum insulated cabinet.
Abstract:
An evaporator system that includes: a first evaporator coil at a first evaporator temperature and pressure; a second evaporator coil at a second evaporator temperature and pressure that is less than the first evaporator temperature and pressure where the first evaporator and second evaporator are configured to be thermally disjointed; and a plurality of thermally conductive spaced apart evaporator fins having a plurality of spaced apart thermal break portions positioned between the first evaporator coil and the second evaporator coil that thermally disjoin the first evaporator and the second evaporator.

Abstract:
A vacuum insulated cabinet structure for refrigerators and the like includes a plurality of vacuum insulated panels. The cabinet structure may include an “O” or “U” structure that is formed by folding a large panel assembly. The panels may comprise side walls that are heat-sealed together around the perimeters of the panels to form air-tight spaces having a vacuum.
Abstract:
A vacuum insulated door structure includes a first wall having a first edge and a barrier layer, a second wall having a second barrier layer and a second edge coupled to the first wall member proximate the first perimetrical edge. The second wall includes at least four inner side walls and a back wall that defines a second wall offset. At least one tubular member extends between the first wall member and the second wall offset, wherein an inner conduit surface of the tubular member provides fluid communication between the first wall outer facing surface and the second wall outer facing surface. A cavity insulation material is disposed within a cavity volume defined between the first and second walls, wherein the cavity volume is hermetically sealed, and wherein the cavity volume includes an at least partial vacuum.
Abstract:
A vacuum insulated cabinet structure includes panels having sheet metal outer side walls and polymer inner side walls. The polymer inner side walls are heat-sealed to a layer of polymer material laminated to a flat sheet metal blank to form vacuum cavities. The blank is then bent along fold lines to form a cabinet structure.
Abstract:
An appliance employing a coolant system that includes a compressor having a housing, a cooling capacity, and operably connected to typically two evaporators for regulating a temperature of the first compartment and a temperature of the second compartment; a shared coolant fluid connection system; a coolant fluid spaced within the shared coolant fluid connection system; and a switching mechanism operably connected to a first fluid conduit that provides shared coolant fluid to the compressor at a first pressure level and a second fluid conduit that provides shared coolant fluid to the compressor at a second pressure level where the second pressure level is less than the first pressure level wherein the switching mechanism is capable of regulating and switching shared coolant flow to the compressor from the first fluid conduit and the second fluid conduit.
