Claims
- 1. A roasting oven comprising:
an outer housing having a lid member; a heating well residing within said housing, said heating well having a bottom surface with integrally formed sidewalls and an open top; heating means including a top heating element disposed in said lid member and a wrap-around heating element radially disposed about said heating well and positioned intermediate said housing and said heating well; temperature controlling means electrically interconnected to said heating means for regulating the temperature of said heating elements; and function controlling means electrically interconnected to said temperature controlling means and to said heating elements enabling said top heating element and said wrap-around heating element to be selectively energized to provide variable cooking modes.
- 2. The roasting oven of claim 1 wherein said wrap-around heating element is formed by wrapping an electrical heating wire about an insulating material along the entire length thereof in a predetermined configuration.
- 3. The roasting oven of claim 2 wherein said insulating material includes a plurality of notches formed in the lateral edges thereof at periodic intervals such that said heating wire can be engaged within said notches in a repeating pattern.
- 4. The roasting oven of claim 3 wherein said heating wire is alternately traversed across said insulating material between diagonally opposed pairs of said notches and then interlaced between adjacent pairs of said notches in a predetermined pattern such that at least 75% of said heating wire is disposed on a first side of said insulating material.
- 5. The roasting oven of claim 3 wherein said insulating material is constructed in the form of an elongated belt.
- 6. The roasting oven of claim 5 wherein said heating wire is wrapped in continuous revolutions about said insulating material between diagonally opposed pairs of said notches to produce said repeating pattern.
- 7. The roasting oven of claim 6 wherein said insulating material including said heater wire is captured between interior and exterior sheets of heat insulating material to form a heating belt assembly.
- 8. The roasting oven of claim 7 wherein said heating belt assembly is riveted at periodic intervals along the length thereof to maintain alignment of said interior and exterior sheets of heat insulating material after installation of said assembly about said heating well.
- 9. The roasting oven of claim 7 wherein said heating belt assembly is enclosed within a protective metallic sheath.
- 10. The roasting oven of claim 8 wherein said heating belt assembly is secured to the external periphery of the side wall of said heating well by an adjustable band clamp.
- 11. The roasting oven of claim 3 wherein said heater wire is tightly intertwined at the terminal ends thereof with a bundle of wire conductors to form a heat sink to insulate said temperature controlling means from said heating element.
- 12. The roasting oven of claim 11 wherein said twisted bundle of heater wire and said wire conductors is covered with a fiberglass insulation sleeve and at least one ceramic sleeve to form a lead wire assembly.
- 13. The roasting oven of claim 3 wherein the terminal ends of said heater wire are encased by a plurality ceramic insulation sleeves disposed thereon to insulate said temperature controlling means from said heating elements.
- 14. The roasting oven of claim 1 wherein said wrap-around heating element is formed by positioning an electrical heating wire in a regular serpentine pattern intermediate opposed layers of insulating materials.
- 15. The roasting oven of claim 1 wherein said wrap-around heating element is formed by positioning at least one electrical heating wire within a metallic heating tube conforming to the external periphery of said heating well, said heating tube being captured within a metallic sheath.
- 16. A roasting oven comprising:
an outer housing having a lid member including electrically conductive supporting means for attaching said lid member to said housing; a heating well residing within said housing, said heating well having a bottom surface with integrally formed sidewalls and an open top; heating means including a top heating element disposed in said lid member, said top heating element being electrically connected to a power source via said electrically conductive supporting means, and a wrap-around heating element radially disposed about said heating well and positioned intermediate said housing and said heating well; temperature controlling means electrically interconnected to said heating means for regulating the temperature of said heating elements; and function controlling means electrically interconnected to said temperature controlling means and to said heating elements enabling said top heating element and said wrap-around heating element to be selectively energized to provide variable cooking modes.
- 17. The roasting oven of claim 16 wherein said electrically conductive supporting means comprises a hinge mechanism wherein an electrical circuit supplying said top heating element is formed in the body of said hinge mechanism.
- 18. The roasting oven of claim 17 wherein said top heating element is electrically connected to a power source by a pin connector attached by electrical wiring to an electrical plug assembly within said hinge mechanism wherein the electrical circuit is completed when said hinge mechanism is in a closed position.
- 19. The roasting oven of claim 18 wherein said lid member is detachable from said housing by disconnection of said electrical plug assembly for cleaning and storage purposes.
- 20. The roasting oven of claim 16 wherein said electrically conductive supporting means comprises a plug connector that engages an electrical receptacle having a permanent magnet integrated therein, said magnet retaining said plug connector at the interface thereof to maintain electrical contact with said top browning element and to secure said lid on said oven simultaneously.
- 21. The roasting oven of claim 16 wherein said housing is provided with handles being pivotable from a locked extended position to a downwardly folded position.
