A heater assembly includes a mounting structure, a securement structure, an insulator support structure, a conducting structure having a first portion and a second portion, a terminal structure, and a thermostat structure. The securement structure cooperates with the insulator support structure and the mounting structure to releasably and fixedly secure the insulator support structure to the mounting structure. The terminal structure is coupled to the first portion of the conducting structure, and is used to deliver power to the conducting structure. The thermostat structure is coupled to the second portion of the conducting structure. The insulator support structure is configured to cooperate with both the terminal structure and the thermostat structure to fixedly support the terminal structure or the thermostat structure in position.

The deep well cooker of claim 2 wherein said mica insulation board 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 deep well cooker of claim 3 wherein said heating wire is alternately traversed across said mica insulation board 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 mica insulation board. 5. The deep well cooker of claim 3 wherein said mica insulation board is constructed in the form of an elongated belt. 6. The deep well cooker of claim 5 wherein said heating wire is wrapped in continuous revolutions about said mica insulation board between diagonally opposed pairs of said notches to produce said repeating pattern. 7. The deep well cooker of claim 3 wherein said heater wire is tightly intertwined at the terminal ends thereof with a bundle of nickel lead wires to form a heat sink to insulate said temperature controlling means from said heating elements. 8. The deep well cooker of claim 7 wherein said twisted bundle of heater wire and said nickel lead wires is covered with a fiberglass insulation sleeve and at least one ceramic sleeve to form a lead wire assembly. 9. The deep well cooker of claim 1 wherein said housing and said deep well member are rectangular in configuration. 10. The deep well cooker of claim 1 wherein said housing and said deep well member are oval in configuration. 11. The deep well cooker of claim 1 wherein said bottom heating element comprises an induction heater including an induction coil capable of generating a high frequency magnetic field for generating heat within said deep well member for cooking. 12. The deep well cooker of claim 1 wherein said bottom heating comprises a hot plate type heater including a heating plate. 13. The deep well cooker of claim 12 wherein said heating plate is constructed in a concave/convex configuration with the concave surface thereof disposed upwardly adjacent said bottom surface of said deep well member to resist heat deformation. 14. The deep well cooker of claim 12 wherein said heating plate is constructed in a convex/concave configuration with the convex surface thereof disposed upwardly adjacent said bottom surface of said deep well member to resist heat deformation. 15. An improved deep well cooker having an outer housing, a deep well member residing within said housing having a bottom surface with integrally formed side walls and an open top defining a cooking pot, a bottom heating element disposed adjacent said bottom surface intermediate said housing and said deep well member, and a temperature control switch electrically interconnected to said bottom heating element wherein the improvement comprises: a wrap-around heating element radially disposed about said side walls and intermediate said deep well member and said housing and electrically interconnected to said temperature control switch; and a multi-function control switch electrically interconnected to said temperature control switch, said bottom heating element, and said wrap-around heating element enabling each of said heating elements to be selectively energized to provide variable cooking modes for said cooker. 16. The improved deep well cooker of claim 15 wherein said bottom heating element comprises an induction heater including an induction coil capable of producing a high frequency electromagnetic field for generating heat within said deep well member for cooking. 17. The improved deep well cooker of claim 15 wherein said bottom heating element comprises a hot plate type heater including a heating plate. 18. The improved deep well cooker of claim 17 wherein said heating plate is constructed in a concave/convex configurat ion with the concave surface thereof disposed upwardly adjacent said bottom surface of said deep well member to resist heat deformation. 19. The improved deep well cooker of claim 12 wherein said heating plate is constructed in a convex/concave configuration with the convex surface thereof disposed upwardly adjacent said bottom surface of said deep well member to resist heat deformation. 66 711, EP; 1 122 248, EP; 1 138 387, EP; 1 221 442, EP; 2166636, JP; WO 00/17178, JP; WO97/047613, WO; WO97/047614, WO; WO99/001445, WO; WO99/007690, WO; WO99/011639, WO; WO 00/07695, WO
