Abstract:
1. An oven comprising: an outer cabinet having interior surfaces; a liner positioned within the outer cabinet and including an outside surface to define an oven cavity that is configured to operate at temperatures of at least 500° F.; an inner layer of fibrous insulation material that engages the outside surface of the liner, the inner layer of fibrous insulation material having a first density and configured to reduce convective heat transfer without having a substantial effect on radiant heat transfer, wherein the inner layer is made from glass fibers, mineral wool, or rock wool; a thermal energy metallic foil reflective layer that engages the inner layer of fibrous insulation material, wherein the thermal energy reflective layer is configured to reflect radiant heat transfer; an outer layer of fibrous insulation material disposed around the thermal energy reflective layer, the outer layer of fibrous insulation material having a second density that is greater than the first density of the inner layer of fibrous insulation material, wherein the outer layer is made from glass fibers, mineral wool, or rock wool; and an air gap provided between the outer layer of fibrous insulation material and the outer cabinet wherein the inner layer of fibrous insulation material, the thermal energy metallic foil reflective layer and the outer layer of fibrous insulation material prevent a temperature of the outer cabinet from exceeding 172° F.
