An apparatus for temperature control of a barbecue oven, in accordance with an exemplary embodiment of the present disclosure. A vent from a firebox feeds heated air with smoke to a cook box. A variable speed motor connected to a blower wheel draws air out of the cook box into a plenum, and also pressurizes the plenum to force air back onto the cook box through one or more vents between the plenum and the cook box, as well as out of the stack. A variable frequency drive is coupled to the variable speed motor and a proportional-integral-derivative (PID) controller, which is coupled to a temperature sensor. When the temperature falls below a set point, the PID controller causes the variable frequency drive to actuate the variable speed motor and draw heated air into the cook box from the firebox. The blower wheel and vents circulate the heated air in the cook box, and the air exhaust through the stack allows heated air to be drawn into the cook box.

This invention provides a portable combustion device that provides a cleaner combustion, provides a more efficient overall combustion through the use of a fan that directs a predetermined volume of airflow over the combustible fuel—typically wood or similar cellulose-based biological solids and provides a cooking surface that is a grill top. The combustion device has a combustion chamber into which the fuel source is placed for combustion. Mounted to the side of the combustion chamber is a housing that encloses the TEG, which generates an electrical output, based on a difference in temperature on opposing sides. Mounted onto the TEG housing and protruding into the combustion chamber through a small passageway is a heat-conducting probe and heat-conducting probe base unit.

The motorized charcoal grill is a commercial grade transportable charcoal grill that is suitable for cooking large quantities of food. The motorized charcoal grill dedicates specific areas for automatic rotisseries, roasting racks, a side grill for quickly cooking small quantities and one or more ovens. The motorized charcoal grill is mounted on heavy duty casters so it can be moved easily. The motorized charcoal grill comprises a master pit, a side pit, a one or more ovens, a frame and a drive.

The invention relates to a grill system for grilling food. The grill system includes a grill surface, a first side surface, a second side surface and a rear surface. The grill surface has four sides and is generally horizontal and surrounded on multiple sides by vertical walls to form an enclosure below the grill surface. The first side surface is adjacent to a first side of the grill surface and the second side surface is adjacent to a second side of the grill surface. The second side surface is on an opposite side of the grill surface from the first side surface. The rear surface is positioned adjacent to a third side of the grill surface and extends between the first side surface and the second side surface. The first side surface, the second side surface and the rear surface are foldable between a first generally horizontal orientation that is generally planar with the grill surface and a second generally vertical orientation that is generally perpendicular to the grill surface.

A combustion powered electricity generating assembly for grilling and generating electricity includes a grill housing, which defines an interior space. A front opening positioned in a front face of the grill housing allows for positioning of combustible materials into the interior space. A front door is hingedly engaged to the grill housing and is positioned to selectively close the front opening. A thermoelectric generator engaged to a back face of the housing generates an electrical current due to a temperature differential between the grill housing and the ambient environment. A power storage module is operationally engaged to the thermoelectric generator so that the power storage module is charged by the electrical current. The power storage module can be engaged an electrical device to power the electrical device.

A firebox for a grill is provided. The firebox has a shell, an insulation layer, and a firebrick layer. The firebrick layer comprising a plurality of firebricks that form an inner peripheral surface of the firebox. The insulation layer formed between the firebrick layer and the shell or the insulation layer forming the outermost layer of the firebox. The shell preventing the collapse and/or unwanted airflow into the internal cavity of the firebox if a fracture is formed in the firebrick layer.

A solid-fuel grilling device comprises a direct-current power source. A direct-current sensor is in communication with the direct-current power source. The direct-current sensor is configured to gather power characteristic data in relation to the direct-current power source. A solid-fuel grilling component is in communication with the direct-power source. The direct-power source provides power to the solid-fuel grilling component. A processor, in communication with the direct-current sensor, is configured to analyze the power characteristic data and determine operational health of solid-fuel grill components.

The invention relates to a solid-fuel combustion device, comprising a fuel reservoir for a solid fuel in the form of fuel pieces and a combustion chamber having at least one first opening for the feeding of air and having at least one second opening for the escape of heat and exhaust gases produced when the solid fuel is burned. During proper use, the fuel reservoir is arranged in such a way that the fuel pieces can enter the combustion chamber under the force gravity and can burn there. The fuel reservoir is closed air-tight at least in such a way that no or at least no significant burning can occur in the fuel reservoir during proper use. During proper use, the first opening is arranged below the combustion chamber and the second opening is arranged to the side of the combustion chamber.

Disclosed is an air circulation device for an outdoor cooking appliance such as a grill. The device helps circulate air more consistently and efficiently by providing slats that direct rising air in a cyclonic arrangement. By providing this cyclonic effect, the air circulation device can distribute heat and smoke more evenly to the food being cooked and improve smoke penetration, heat efficiency, and the evenness of cooking.

A grill system having a housing, a frame, movably imbedded inside the housing through a top of the housing, a grate covering a top of the frame, a wheel adjacent to a side of the housing, connected to a wheel shaft, parallel to the grate and connected to the frame, a lock securing the wheel in set positions, and a heat source inside the frame below the grate and above the wheel shaft. The wheel and wheel shaft being rotatable such that the frame and the grate are raised or lowered out of or into the housing as the wheel and wheel shaft rotate. The heat source is movable independent from the wheel, wheel shaft, frame, and grate, and the grate cannot be lowered below the heat source.
