Abstract: A combustion chamber has an inner wall defining an inner chamber. The inner wall is perforated to admit combustion air into the inner chamber. The combustion chamber has an outer wall defining an outer chamber. The outer wall is perforated to admit combustion air from a pressurized air plenum to the inner wall. The inner and outer wall are spaced apart such that air may flow between the inner and outer walls.

Abstract: An enclosure for use in a cooking grill. The enclosure has a lower portion defining an opening that receives combustion gases from a combustion source via a bottom opening, and an upper portion interposing the lower portion and the cooking grate and having a floor with an opening that receives the lower portion and combustion gases therefrom and directs them to the cooking grate. The floor slopes to a grease drain.

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 system includes a smoker having a cooking chamber and a firebox in fluid communication with the cooking chamber. The system includes a cooking grate within the cooking chamber, a first exhaust opening in the cooking chamber proximate the firebox, and a plurality of generally horizontal baffles below the cooking grate. At least one of these is situated near the firebox to direct smoke away from the firebox before it rises above a level of the cooking grate.

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 floor and an upright sidewall formed from two vertically coaxial components, each component having a floor baffle with a plurality of floor openings defined therein, each floor retained within a respective upright sidewall with a plurality of sidewall openings defined therein. The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.

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: A combustion chamber has an inner wall defining an inner chamber. The inner wall is perforated to admit combustion air into the inner chamber. The combustion chamber has an outer wall defining an outer chamber. The outer wall is perforated to admit combustion air from a pressurized air plenum to the inner wall. The inner and outer wall are spaced apart such that air may flow between the inner and outer walls.

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 device has a cooking chamber and a firebox affixed to a bottom of the cooking chamber and in fluid communication with the cooking chamber.

Abstract: A burner system for use in a gas cooking grill has a primary burner in a firebox providing heat to a cooking surface above the primary burner and a secondary burner in the firebox selectively providing heat to a cooking grate such that ignition of the secondary burner provides an additional degree of heat to the cooking surface above the primary burner.

Abstract: A cooking grill has a firepot configured to burn pelletized fuel fed from an auger, a cooking grate above the firepot, and a double walled enclosure interposing the firepot and the cooking grate and containing and directing flow of combustion gases from the firepot up to the cooking grate.

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: A control system for a pellet fueled cooking device includes at least two adjustable smokestacks selectively allowing combustion gases to escape from a cooking chamber, and an air adjustment mechanism being adjustable between a first position where air flow into a firepot is substantially blocked and a second position where airflow into the firepot is allowed.

Abstract: A floor and an upright sidewall formed from two vertically coaxial components, each component having a floor baffle with a plurality of floor openings defined therein, each floor retained within a respective upright sidewall with a plurality of sidewall openings defined therein. The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.
