Because of the increased cross-sectional thickness of the polyurethane inner frame 32 in certain portions, the conduits 370 are typically disposed within the support portions 160 and the outwardly expanding framing members of the polyurethane inner frame 32. In this manner, the conduits 370 provide a path of travel through the vacuum panel cabinet structure 30 while minimizing the loss of insulative properties of the vacuum panel cabinet structure 30 due to the loss of material as a result of the conduits 370.
  • the typical cross-sectional thickness of the vacuum panel cabinet structure 30 constructed, as described above can be approximately 15 mm measured from the outward surface 74 of the outer enclosure 70 to the liner inner facing surface 108.
  • a step 402 of this method 400 includes providing the polyurethane inner frame 32 having the at least four side framing members 34 that define the inner frame opening 36, where the polyurethane inner frame 32 also includes the plurality of framing edges 38, the back framing member 40 coupled to at least one of the plurality of framing edges 38, the at least one outwardly expanding framing member is disposed proximate at least one of the plurality of framing edges 38, the inner facing surface 44, and the outer facing surface 46.
  • the at least four side frame members and the back framing member 40 define the plurality of panel receptacles 48.
  • Another step 404 in the method 400 includes providing the plurality of vacuum insulated panels 50 configured for reception in the plurality of panel receptacles 48.
  • the method 400 also includes the step 406 of providing the outer enclosure 70 and disposing the at least one outwardly contoured hinge 80 onto the outer enclosure 70 proximate one of the outwardly expanding framing members, wherein the outwardly contoured hinge 80 includes an extension arm 256 that extends around the outwardly expanding framing member.
  • the outwardly contoured hinge 80 can include the hinge body 250, the reinforcing portion 252, and the connection members 254 that couples the hinge body 250 to the reinforcing portion 252 and disposes the outwardly contoured hinge 80 to the outer enclosure 70.
  • Another step 408 in the method 400 includes providing the liner 100 having a perimeter flange 112 that extends from a liner opening 104 to a liner perimetrical edge 114.
  • Another step 410 in the method 400 includes disposing the vacuum insulated panels 50 within the plurality of panel receptacles 48.
  • the method 400 also includes the step 412 of disposing the barrier film 52 comprising a hermetic barrier film and a heat sealing layer onto at least a portion of the vacuum insulated panel 50 and at least a portion of the polyurethane inner frame 32.
  • Another step 414 in the method 400 includes disposing the polyurethane inner frame 32 with the vacuum insulated panels 50 and the barrier film 52 disposed thereon into the structure receptacle 84 of the outer enclosure 70. In this manner, the inward surface 82 of the outer enclosure 70 engages at least a portion of the outer facing surface 46 of the polyurethane inner frame 32.
  • Yet another step 416 in the method 400 includes disposing the liner 100 within the inner structure opening, such that the liner outer facing surface 110 is disposed proximate the inner facing surface 44 of the polyurethane inner frame 32.
  • the liner perimetrical flange 112 of the liner 100 is then disposed to the enclosure rim 74 of the outer enclosure 70 to define the vacuum panel cabinet structure 30.
  • Yet another step 418 in the method 400 includes hermetically sealing the liner 100 to the outer enclosure 70 such that the perimetrical edge 114 of the liner 100 is disposed proximate the enclosure rim 76 of the outer enclosure70.
  • This step 418 can also include providing at least one infrastructure notch 130 defined by the vacuum panel cabinet structure 30, such that the at least one infrastructure notch 130 is disposed proximate the liner perimetrical flange 112.
  • a filler material is disposed within the infrastructure notch 130 to hermetically seal the infrastructure notch 130.
  • This step also includes selectively disposing a gasket 134 on at least a portion of the liner perimetrical flange 112 such that, when the gasket 134 selectively engages the liner perimetrical flange 112, the gasket 134 further seals the infrastructure notch 130.
  • the term "coupled” in all of its forms, couple, coupling, coupled, etc. generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated.
  • elements shown as integrally formed may be constructed of multiple parts or elements shown as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connector or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied.
  • the elements and/or assemblies of the system may be constructed from any of a wide variety of materials that provide sufficient strength or durability, in any of a wide variety of colors, textures, and combinations. Accordingly, all such modifications are intended to be included within the scope of the invention as defined by the claims. Other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangement of the desired and other exemplary embodiments without departing from the scope of the invention as defined by the claims.
