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 using alternative construction methods 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. In alternative embodiments the bottom heating element comprises an induction heater including an induction coil capable of generating an electromagnetic field to generate heat for cooking and also a hot plate type heater including a concave/convex heating plate which resists heat deformation.
