Gas burner, particularly for household cooking appliances, with an horizontal or vertical gas supply conduit (), a burner body with one more flame crowns, an horizontal or vertical Venturi (), a nozzle () to inject the gas flow from said gas conduit into said Venturi pipe and, means to provide the primary air flow which include a tubular conduit which is coaxial and placed outside said gas conduit, and an opening to allow the gas flow, placed between said nozzle and the inlet of the Venturi pipe. The coaxial conduit draws the respective air flow from a zone inside the body of said cooking appliance, and said opening allows the passage of the respective primary air flow sucked and coming from over the appliance top surface (). In order to stir the primary air flow passing through said coaxial conduit, a plurality of radial wings (A) is arranged, said wings being shaped either planar or helical, and being connected on the outer surface of said gas supply conduit.

Gas burner with improved primary air duct

A gas stove having an upper work plate with at least one integrated gas burner, said gas burner including a bowl-shaped base body, a burner crown, and an upper cap, with several flame ports provided to let out a gas-air mixture towards a recipient to be heated, and an annular mixing zone, whose cross section incrementally expands towards the flame ports, defined between the burner crown and the upper cap with the burner crown including a Venturi pipe which feeds the gas-air mixture into the mixing zone and is designed to suck primary air from above the upper work plate the flame ports are formed in the upper cap as through-holes, and the bottom side of the upper cap, which defines the upper side of the mixing zone, is at least partially inclined upwardly towards the flame ports to define the incrementally expanding cross section of the mixing zone.

Gas stove

Burner assembly

A gas burner with a plurality of concentric flame crowns including a burner body, a first central burner, and a second outer annular burner surrounding the first central burner, where the first central burner includes a first diffusion chamber and a first gas injector configured to inject a gas flow into a first Venturi pipe which is configured to convey the gas flow to the first diffusion chamber, and where the second outer annular burner includes two separate outer diffusion chambers and two distinct outer injectors each of which is configured to inject a gas flow into one of two outer Venturi pipes which are configured to convey the gas flows to the two separate outer diffusion chambers, and where the first gas injector, the first Venturi pipe, and the two outer Venturi pipes are substantially horizontally oriented.

Gas burner

Gas burner provided with a plurality of concentric flame crowns, and comprising a first central burner to supply a peripheral flame ring, a second annular burner surrounding the central burner at a defined distance and able of supplying at least a respective peripheral ring, a burner body apt to be mounted on the surface of a cooking hob, a first gas inlet in communication with the body, a first vertical gas injector, the central burner being provided with a first chamber for the diffusion of the air/gas mixture, a second gas inlet in communication with the body, wherein the second annular burner is provided with two separate chambers for the diffusion of the mixture, wherein the second gas inlet is in communication with the two separate chambers through suitable injection and conveying means, which comprise two distinct injectors in communication with the second gas inlet, and two respective horizontal Venturi pipes each of which being able of supplying with the air/gas mixture a respective of the two diffusion chambers; these are physically separate and not in communication to each other. The two horizontal and separate injectors are placed on the same end position of the second gas inlet.
