Abstract
A multifunctional cooking system including a deep well cooker that includes a bottom heating element and a wrap-around heating element which are disposed about the deep well member for heating the side walls thereof is disclosed. The heating elements are fabricated in alternative embodiments to provide one-sided or double-sided configurations for particular applications. Both the bottom heating element and the wrap-around heating element are electrically interconnected by a temperature controlling device for heat regulation and a multi-function controller for selectively energizing the heating elements individually or in combination for various cooking modes.
Claims19
A deep well cooker comprising:
- an outer housing having a lid member;
- a deep well member residing within said housing, said deep well member having a bottom surface with integrally formed sidewalls and an open top;
- heating means including a bottom heating element and a wrap-around heating element radially disposed about said deep well member and positioned intermediate said housing and said deep well member;
- 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 bottom heating element and said wrap-around heating element to be selectively energized to provide variable cooking modes.
An improved deep well cooker having an outer housing, a deep well member residing within said housing and also 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.
A method of fabricating a wrap-around heating element for a deep well cooker, said method comprising the steps of:
- producing an elongated sheet of supporting insulation board with preset dimensions;
- cutting a plurality of opposed notches into the lateral edges of said insulation board at predetermined intervals;
- providing an electrical heating wire having terminal ends;
- wrapping said electrical heating wire about said insulation board to engage said notches in a repeating pattern;
- layering said supporting insulation board with said heating wire wrapped thereon between interior and exterior sheets of insulation board;
- fastening said sheet of supporting insulation board to said interior and said exterior sheets of insulation board at predetermined locations to permanently capture said supporting insulation board therebetween;
- providing a bundle of nickel conductors;
- twisting said terminal ends of said heating wire with said nickel conductors using a predetermined tension;
- applying a fiberglass insulation sleeve to said twisted wire bundle;
- attaching at least one ceramic insulation sleeve over said fiberglass insulation sleeve;
- crimping a wire connector onto each end of said terminal ends to produce a lead wire assembly;
- and
- attaching said wrap-around heating element to an adjustable band clamp for installation about said deep well cooker.
