The chassis is defined with a through hole. A bottom of the mounting bracket is mounted on the chassis and a top of the mounting bracket is mounted on the cover. The ceramic plate is defined with air holes and provided on the mounting bracket. The ceramic plate is enclosed with the mounting bracket. The chassis and the cover to form a combustion space. The hollow air column is defined with air holes and passes through the through hole to extend into the combustion space. A bottom of the strengthening net is connected with the chassis and a top of the strengthening net is connected with the cover, and the strengthening net is provided outside the ceramic plate.

An infrared temperature equalizing device and a grill thereof having a first vertical plate, a first folded plate, a second vertical plate, and a second folded plate. The first folded plate is connected with the second folded plate to form a cover. The first vertical plate and the second vertical plate form a wall. The wall and the cover form a heat aggregation chamber for hot air aggregation and circulation, which has a closed top and a bottom opening with a longitudinal depth. The temperature equalizing device achieves heat aggregation, temperature rising, and temperature equalizing. Through infrared and convection heating, the grill can heat food evenly and roast the food quickly.

A combustion device includes a first cover, a second cover, an infrared generating mesh, and a gas burner assembly, wherein the first cover has a plurality of through holes. A first half portion of the second cover has at least one hollow portion. A second half portion of the second cover is closed. The infrared generating mesh is disposed between the first cover and the second cover. A flame outlet of the gas burner assembly is located within a projection area of the second half portion. In this way, the intensity of the infrared rays generated by the combustion device could be increased and could be uniform.

The disclosure relates to a gas-heated infrared radiation emitter comprising at least one radiating screen, which is for example made of ceramic and/or metal, in the form of at least one plate comprising a lower main surface and an upper main surface that are distant from each other, and a plurality of through-prisms, which are preferably hollow, extending from the lower main surface to the upper main surface, each prism being defined by a polygonal base and by an axis. The prisms may be juxtaposed with one another so that their polygonal bases form a tiling of at least one portion of the lower and upper main surfaces of said plate.
