the metal clad covering 320 defines a cabinet receptacle 328 for receiving the exterior
surface 326 of the vacuum panel cabinet structure 30. In various other alternate embodiments,
the exterior surface 326 of the vacuum panel cabinet structure 30 can include the
finished outer surface 322. In such an embodiment, the metallic finishes described
above, or various indicia, patterns, or colors can be disposed on the exterior surface
326 of the vacuum panel cabinet structure 30.
[0034] Referring now to the embodiment as illustrated in FIGS. 17-19, the infrastructure
notch 130 of the vacuum insulated cabinet structure is disposed proximate the liner
perimetrical flange 112 and includes the filler member 132 that hermetically seals
the infrastructure notch 130. The infrastructure notch 130 is configured to receive
and provide a path of travel for at least a portion of the cooling loop 14 that supports
the mechanical aspects of the refrigerator 10 disposed in the cavity recess 300. The
cooling loop 14 is configured to pass through the infrastructure notch 130 and into
the interior 12 of the refrigerator 10 to additional mechanical aspects that can include,
but are not limited to, evaporators, specialty cooling modules, and other mechanical
aspects of a refrigerator 10. Where the cooling loop 14 passes through the infrastructure
notch 130, the filler material provides a hermetic seal within the infrastructure
notch 130 and around the portion of the cooling loop 14 disposed within the infrastructure
notch 130. In various embodiments, the gasket 134 can be disposed on at least a portion
of the liner perimetrical flange 112 proximate the infrastructure notch 130 to further
seal the infrastructure notch 130. It should be understood that the location and number
of infrastructure notches 130 can vary depending upon the cooling features and other
mechanical features included within the refrigerator 10. In this manner, the use of
the infrastructure notches 130 substantially limits the need to provide conduits 370
or other openings through the vacuum panel cabinet structure 30. The number and size
of openings in the vacuum panel cabinet structure 30 that need to be installed within
the vacuum panel cabinet structure 30 are thereby limited, while also providing for
the mechanical functions of the refrigerator 10.
[0035] As illustrated in FIGS. 20-21, in various embodiments, a magnetic gasket 330 is included
on the vacuum panel cabinet structure 30 proximate the liner perimetrical flange 112
and a mullion edge 218 of the mullion member 210 at a cabinet rim 336 to provide a
seal between the at least one door 262 and the vacuum panel cabinet structure 30.
The magnetic gasket 330 substantially seals the interior 12 of the refrigerator 10
and substantially limits the amount of cooling that escapes the interior 12 of the
refrigerator 10 when the at least one door 262 is in the closed position. The magnetic
gasket 330 includes a gasket channel 338 that is configured to engage the cabinet
rim 336 and extend around at least a portion of an interior surface 340 of the vacuum
panel cabinet structure 30. A tubular extruded portion 342 is disposed proximate the
gasket channel 338, wherein the tubular extruded portion 342 includes at least one
elongated magnet member 344. The elongated magnet member 344 is configured to engage
a magnetic portion 332 disposed on at least a portion of the at least one door 262
of the refrigerator 10. In various embodiments, the magnetic portion 332 can include,
but is not limited to, the outer enclosure 70 or the metal clad covering 320.
[0036] As illustrated in FIGS. 20-21, the elongated magnet member 344 selectively cooperates
with the magnetic portion 332 disposed on the at least one door 262 to bias the at
least one door 262 toward the cabinet rim 336 when the at least one door 262 is disposed
in or substantially near the closed position. As the door 262 moves to the closed
position, the elongated magnet member 344 is pulled toward the magnetic material,
thereby extending the tubular extruded portion 342 such that the elongated magnet
member 344 can outwardly extend toward and engage the magnetic portion 332 of the
door 262. The tubular extruded portion 342 includes a compression limiting channel
334 that is configured to substantially prevent the tubular extruded portion 342 from
fully compressing, thereby substantially limiting damage that may occur when the at
least one door 262 is closed in a rapid or forceful manner.
[0037] As illustrated in FIGS. 20-21, the magnetic gasket 330 includes at least one flared
tubular member 346 disposed proximate the tubular extruded portion 342 and the at
least one elongated magnet member 344. At least one extruded flange 348 is disposed
proximate the at least one flared tubular member 346, wherein the at least one flared
tubular member 346 and the at least one extruded flange 348 are configured to further
engage at least a portion of a perimeter recess 350 of the at least one door 262.
In this manner, when the at least one door 262 is placed in the closed position, the
at least one flared tubular member 346 and the at least one extruded flange 348 are
compressed against the perimeter recess 350 of the at least one door 262 to create
a seal between the at least one door 262 and the cabinet rim 336 of the vacuum panel
cabinet structure 30.
[0038] Referring now to FIGS. 7-8, the vacuum panel cabinet structure 30 can include one
or more conduits 370 disposed within the polyurethane inner frame 32 to provide a
path of travel for mechanical and electrical aspects of the refrigerator 10 through
the vacuum panel cabinet structure 30 and the refrigerator 10 in general. 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.
[0039] In various embodiments, 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. Portions of the vacuum panel cabinet structure 30, which can include, but are
not limited to, the support portions 160 and the outwardly expanded framing members
42, typically have a greater thickness. It should be understood that the vacuum panel
cabinet structure 30 can be configured to have a variety of minimum cross-sectional
thicknesses that can be greater than 15 mm.
[0040] Another aspect of the vacuum panel cabinet structure 30, as illustrated in FIG. 22,
includes a method 400 for creating the vacuum panel cabinet structure 30. 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] Another step 410 in the method 400 includes disposing the vacuum insulated panels
50 within the plurality of panel receptacles 48.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
