A heater includes an enclosure, a first baffle plate, and a second baffle plate. The enclosure includes a first wall, a second wall opposite the first wall, and a top plate extending between the first wall and the second wall and cooperating with the first wall and the second wall to at least partially define an interior. The heating module is coupled with the enclosure and is disposed beneath the first baffle plate and the second baffle plate. The heater can additionally or alternatively include an air quality monitoring system and an isolation transformer. The air quality monitoring system includes an air quality controller, at least one air quality sensor, and a power input. The isolation transformer is configured to deliver power from the air quality monitoring system to a fuel system controller of the heating module to facilitate powering thereof.

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 domestic cooking appliance for heating a food item includes a main housing; a cooking compartment in the main housing, the cooking compartment being configured to receive the food item to be heated; a shelf located in the cooking compartment and configured to support the food item to be heated; a gas burner configured to provide heat to the cooking compartment; and a perforated panel located between the gas burner and the shelf, the perforated panel having a plurality of openings.

A stove includes a stage, a stove, a housing, and an exhaust pipe is disclosed. Wherein, the stove is disposed on the stage and includes a chamber made of metal and a thermal insulation structure. The chamber includes a cavity, an entry, and an air outlet. The thermal insulation structure covers an exterior of the chamber. The housing is disposed outside of the stove and joined to the stage. An isolation space is formed between the housing and the stove. The exhaust pipe passes through the housing and communicates with the air outlet and the exterior of the housing. The heat source is adapted to heat the cavity. Whereby, a compact size kiln is realized.

Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.

A combustion device includes at least one burner, a supporting assembly, and an infrared ray generation assembly. The at least one burner includes a flame outlet and is adapted to burn gas. The supporting assembly includes a cover plate which has an opening and a plurality of holes, wherein the opening is corresponding to the flame outlet. The infrared ray generation assembly is disposed on the supporting assembly. The infrared ray generation assembly includes an infrared ray generation mesh which includes an emission surface which is adapted to emit infrared ray and corresponding to the plurality of holes. The heating efficiency of the combustion device can be effectively increased by generating an open fire and infrared rays as well as uniform heating.
