Abstract
A refrigeration apparatus enclosure structure wherein an inner laminate wall portion of the enclosure defines the inner sheet liner and insulation disposed within an outer cabinet portion of the enclosure and is secured to a portion of the cabinet wall with the sheet liner portion maintained spaced from the cabinet wall to provide thermal insulation therebetween. The laminate wall is secured to the cabinet by insulative support means extending through openings in the insulation to the sheet liner and means are provided for securing the sheet liner to the inner end of the insulative supports. The insulating supports may further support other elements within the enclosure inwardly of the sheet liner.
Claims19
A refrigeration apparatus enclosure structure comprising:
- an outer cabinet;
- a preformed inner, laminate wall within said outer cabinet defined by unitary construction of an inner sheet liner having an outer surface bonded to outer insulation confronting said outer cabinet, said insulation having a plurality of preformed openings therethrough, said sheet liner comprising the inner wall element of the enclosure structure;
- insulative support means secured to said cabinet and extending forwardly therefrom to be received in said openings in said insulation and terminate at said outer surface of said sheet liner, the laminate wall being positioned in preselected relationship to said outer cabinet by the disposition of said support means in said preformed openings whereby the sheet liner is fully spaced from said outer cabinet;
- and securing means securing said sheet liner to said support means for securing said sheet liner in preselected positioned relationship of said laminate wall with said cabinet wall whereby said sheet liner is in thermally insulated relationship to said cabinet.
A refrigeration apparatus enclosure comprising:
- an outer cabinet having a rear wall, a top wall, and a bottom wall;
- support post means secured to said rear wall of said cabinet;
- a first and a second inner laminate wall within said outer cabinet each defined by a unitary construction of an inner sheet liner and outer insulation extending between said inner sheet liner and said outer cabinet, said first inner laminate wall positioned against a rear wall of said cabinet and defining openings fitted over said support post means, said first laminate wall inner sheet liner overlying the inner end of the support post means, said first inner wall including an upper portion positioned a preselected distance below said cabinet top wall as a result of the fitting of said rear wall over said support post means, said second laminate wall inner sheet liner having folded corner portions to conform the laminate to the contours of said outer cabinet, said second wall insulation being cut through at said folded portions to define voids outwardly of said folded sheet liner portions;
- and insulation means filling said voids.
