Refrigeration apparatus enclosure structure

Claim 2

In a refrigeration apparatus enclosure having an outer cabinet, an improved corner construction comprising: inner laminate wall means within said outer cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said inner laminate wall means defining a corner portion conforming to a corner contour of said outer cabinet, said corner portion defining a continuous liner corner portion and a void outwardly of said corner liner portion; and foamed-in-place insulation means filling said void and bonded to all surfaces confronting said void including those of said outer cabinet, said liner, corner portion, and said outer insulation.

Claim 3

The refrigeration apparatus enclosure of claim 1 wherein said inner laminate wall means includes an inner laminate wall having said inner liner folded to form at least one of said corner portions and said insulation cut through outwardly of said folded corner portion to define said void at said one corner portion.

Claim 4

A refrigeration apparatus enclosure comprising: an outer cabinet defining a back, side, top and bottom walls; a first U-shaped inner laminate wall element within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said inner liner of the first element having folded continuous corner portions to conform said first element to the contours of a portion of said outer cabinet walls, said insulation being slit through outwardly from said folded portions to define voids; a second U-shaped inner laminate wall element within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said inner liner of the second element having folded continuous corner portions to conform said second element to the contours of another portion of said outer cabinet walls, said insulation being slit through outwardly from said folded portions to define voids; foamed-in-place insulation filling said voids; and an inner laminate wall portion within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said cabinet back wall cooperating with said first and second laminate wall elements To insulatively line the interior of the cabinet.

Claim 5

A refrigeration apparatus enclosure comprising: an outer cabinet defining a back, side, top and bottom walls; a first U-shaped inner laminate wall element within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said inner liner of the first element having folded continuous corner portions to conform said first element to the contours of a portion of said outer cabinet walls, said insulation being slit through outwardly from said folded portions to define voids; a second U-shaped inner laminate wall element within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said inner liner of the second element having folded continuous corner portions to conform said second element to the contours of another portion of said outer cabinet walls, said insulation being slit through outwardly from said folded portions to define voids; foamed-in-place insulation filling said voids; and an inner laminate wall portion within said cabinet defined by an inner sheet liner and outer insulation extending between said inner sheet liner and said cabinet back wall cooperating with said first and second laminate wall elements To insulatively line the interior of the cabinet.

Claim 6

The refrigeration apparatus enclosure of claim 3 wherein said first and second U-shaped laminate wall elements are positioned in confronting relationship.

Claim 7

The refrigeration apparatus enclosure of claim 4 including divider wall means extending across the interior of the cabinet for dividing the interior into a plurality of compartments.

Claim 8

The refrigeration apparatus enclosure of claim 5 wherein said first and second U-shaped wall elements are spaced apart adjacent said divider wall means.

Claim 9

The refrigeration apparatus enclosure of claim 5 wherein said first and second U-shaped wall elements are spaced apart adjacent said divider wall means and said divider wall means covers the gap therebetween.

Claim 10

The refrigeration apparatus enclosure of claim 5 wherein said divider wall comprises an insulated wall, and bracket means mounting said insulated wall to said first and second laminate wall elements.

Claim 11

The refrigeration apparatus enclosure of claim 4 wherein said cabinet portion defines a lower portion of said outer cabinet including said bottom wall and said first laminate wall defines an upwardly opening U-shaped wall conforming to the contours of said lower portion; and said other cabinet portion defines an upper portion of said outer cabinet including said top wall, and said second laminate wall defines a downwardly opening U-shaped wall conforming to the contours of said upper portion.

Claim 12

The refrigeration apparatus enclosure of claim 3 including adhesive means for securing said laminate wall elements to said cabinet.

Claim 13

The refrigeration apparatus enclosure of claim 3 including means for securing said laminate wall portion to said cabinet back wall in spaced relationship to said cabinet walls, and insulation means disposed between the periphery of said third inner laminate wall and said cabinet walls.

Claim 14

The refrigeration apparatus enclosure of claim 3 including means for securing said laminate wall portion to said cabinet back wall in spaced relationship to said cabinet walls, and foamed-in-place insulation means disposed between the periphery of said laminate wall portion and said cabinet walls.

Claim 15

The refrigeration apparatus enclosure of claim 3 wherein said laminate insulation includes an outer vapor barrier portion.

Claim 16

The refrigeration apparatus enclosure of claim 3 including sealant means for sealing said sheet liner of said first and second laminate wall elements to said sheet liner of said laminate wall portion.

Claim 17

The refrigeration apparatus enclosure of claim 3 including said first and second U-shaped wall elements spaced apart to define another void, and foamed-in-place insulation filling said other void.
