Abstract: A cooking grill has a cooking chamber containing a cooking grate, a solid fuel fire pit beneath the cooking chamber, an ignitor in the fire pit, a fire chimney interposing the fire pit and the cooking chamber, a fuel hopper attached to a fuel chute directing solid fuel from the hopper into the fire pit by gravity, and a fan directing combustion air into the fire pit.

Abstract: The invention relates to a cooking system utilizing a single-zone or multi-zone induction-based griddle that provides uniform heat across a cooking surface. The system provides a larger cooking surface, a shorter warmup time, and a more targeted heating with a more uniform temperature distribution. A multi-layer cooking surface may converting a magnetic field into a thermal field by employing ferritic stainless steels, e.g., in an upper and lower layer. A middle layer(s) enhances heat transfer towards the entire cooking surface and stores a proper amount of heat inertia in the system. The middle layer, e.g., of aluminum, copper, or carbon-based materials may be separated into zones separated by cavities filled with insulation materials. The system may be utilized for indoor or outdoor grills.

Abstract: An electric grill includes a firebox divided into a plurality of zones. Each zones has an electric heating element, and a temperature probe. A controller having operative control to detect temperatures using the temperature probes adjusts power to the electric heating element for each of the plurality of zones.

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 cold smoke system having a smoke chamber member mounted to a frame. The chamber member defines a receptacle for receiving a combustible fuel source for producing smoke. An ignitor ignites the fuel source. A fan moves air and smoke through the receptacle and into, e.g., a grill cooking chamber. A floor of the chamber member defines an ignitor slot for receiving the ignitor and defines ash openings for allowing to fall out of the receptacle into a tray. The smoke chamber member may be rotationally mounted to the frame. The receptacle has an increasing cross-sectional area in a direction of air flow through the receptacle. A fuel container containing the fuel source is received in the receptacle of the chamber member. The fuel container may have a shape that corresponds to the shape of the receptacle and may be constructed of the same material as the fuel source.

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.
