Abstract: A coil system for inductive heating of a cooking surface including at least one coil having a continuous winding from a center region to an outer region. A spacing within adjacent wires in the winding varies between a center of the winding and an outer portion of the winding.

Abstract: An outdoor cooking grill has a cooking surface and at least one induction coil below the cooking surface. A power supply provides current to the at least one induction coil heating the cooking surface.

Abstract: A cooking system including a cooking chamber with a cooking surface therein, at least one resistive heating element providing heat to the cooking surface, an alternating current connection for powering the resistive heating element, and a direct current source.

Abstract: A cooking grill utilizes at least one resistive heating element below a cooking grate and radiating heat to the cooking grate when a voltage is applied thereto. A first power source provides an alternating current, and a second power source provides a direct current. First and second power sources provide voltage to the at least one resistive heating element individually or simultaneously.

Abstract: An electric cooking grill includes a firebox having a first and second heating elements, first and second cooking surfaces positioned over the first and second heating elements respectively, a household power connection, and a power dividing circuit that apportions power from the household power connection to one or both of the first and second heating elements. At least of the first and second heating elements receives up to 100% of the power from the household power connection.
