An infrared radiation heater includes: a combustion chamber having a combustion space that is open on one side; a combustion device provided in the combustion chamber to combust air-fuel mixture made by mixing fuel with air; and a radiator configured to be heated by heat generated from the combustion device and including a radiation plane configured to emit infrared radiation. The combustion device includes: a nozzle provided in a flow path of the air to inject the fuel; a tubular body including a side surface that faces a direction with a predetermined angle with respect to the radiation plane, and a plurality of voids being formed on the side surface; and an ignition device provided outside of the tubular body and configured to ignite the air-fuel mixture. The air-fuel mixture flows into the tubular body, and the tubular body releases the air-fuel mixture from the voids into the combustion chamber.

A radiant heating assembly including a burner for heating a heat exchanger and a reflector generally disposed about the heat exchanger. The reflector comprising a base defining a first air chamber. The reflector may also comprise one or more wings removably coupled to the base. The wings may be configured to define a second air chamber. The radiant heating assembly may also comprise an air circulation pump configured to draw air through the air chamber of the base and/or wing and provide the air to the burner to improve the efficiency of the combustion process.

Devices and methods for reflecting at least a portion of the heat output of a space heater are described. A supplementary reflector is positioned to reflect a portion of the heat generated by the space heater. The supplementary reflector can be angled relative to the vertical axis to direct reflected heat downwards, while also providing adjustable side panels that provide focus and further direction of the reflected heat.

A kamado-style grill assembly includes a vessel, a fire bowl, and a unit extending through an opening of the vessel for positioning below an opening of the fire bowl. The unit may include a gas burner configured to radiate heat into the fire bowl. In such examples, the grill assembly may further include a heat spreader removably coupled to the unit The heat spreader is formed at least partially of a thermally conductive material to absorb heat radiated from the gas burner and spread heat away from the gas burner. In other examples, the grill assembly may additionally and/or alternatively include a support bracket removably coupled to the fire bowl. The support bracket extends across at least a portion of an opening of the fire bowl for supporting a structure. Other example kamado-style grill assemblies and methods of installing components of kamado-style grills are also disclosed.

A combination type cooker may include a top plate with a surface, a case that is configured to define a space shielded by the top plate, a gas burner that is provided inside the case, and in which a heat plate is heated by combustion of a fuel gas, an induction burner that is provided inside the case, and that is configured to heat a cooking container by induction, and a barrier that is provided between the gas burner and the induction burner, and that is configured to partition an inside of the case into a first space where the gas burner housed, and a second space where the induction burner is housed.

A plaque for a radiant heating system can include a main body defining an outer surface and a plurality of pores defined within the main body, wherein at least some of the plurality of pores are disposed in a non-parallel relationship with at least some others of the plurality of pores, or wherein at least some of the pores are parallel with each other. A burner assembly including a plurality of adjacently arranged plaques reduces the ignition time and delay for adjacent plaques after the central plaque has been ignited.

An oven appliance defines a vertical direction, a lateral direction and a transverse direction. The vertical, lateral and transverse directions are mutually perpendicular. The oven appliance includes a cabinet extending between a first side portion and a second side portion along the lateral direction. The cabinet also extends between a top portion and a bottom portion along the vertical direction. The cabinet defines an upper cooking chamber positioned adjacent the top portion of the cabinet and a lower cooking chamber positioned adjacent the lower portion of the cabinet. The oven appliance also includes a single heat source in thermal communication with an ambient environment around the oven appliance by natural convection and a fan operable to provide direct thermal communication from the single heat to one or both of the upper cooking chamber and the lower cooking chamber by forced convection.

Provided is a cooking device. The cooking device includes a frame to form a cooking chamber; a burner to heat the cooking chamber; a gas valve to control a flow of a gas which will be supplied to the burner; an ignition unit to ignite a mixed gas of the gas and air which is supplied to the burner; a fan to enable the air heated by the burner to flow; a fan motor to rotate the fan; and a control unit to control the fan motor, wherein, when the fan motor is normally operated, the control unit turns on the gas valve and operates the ignition unit.

A grill including an upper shell and a lower shell is provided. The lower shell defines an opening there-through, and the upper shell and the lower shell together define a cooking chamber. A pellet burner is adapted to fit in the opening in the lower shell. The pellet burner includes an air duct having a first end and a second end. The first end is positioned outside of the lower shell and the second end is positioned inside of the lower shell when the pellet burner is fitted in the opening in the lower shell. The pellet burner includes a fan positioned to blow air through the air duct and through the second end of the air duct, and a pellet box configured to hold a plurality of pellets. An auger moves the pellets to a position adjacent the second end of the air duct that contains a hot rod.

A kiln includes a stove, a combustion device, and an exhaust pipe, wherein the stove includes a cavity, an entry, and an air outlet. The cavity includes a front section and a rear section, and a top wall surface of the front section is tilt. The air outlet is disposed between a top of the front section of the cavity and the entry. The combustion device is disposed in the rear section. The combustion device includes at least one burner, a supporting assembly, and an infrared ray generation assembly. The supporting assembly includes a cover plate having a hollow portion. The infrared ray generation assembly is mounted to the supporting assembly and located above the cover plate. The infrared ray generation assembly could be heated by the flames of the burner to generate infrared ray which passes through the hollow portion. The exhaust pipe communicates with the air outlet.
