Patent number: 9909758Abstract: Gas burner, particularly for household cooking appliances, with an horizontal or vertical gas supply conduit (1), a burner body with one more flame crowns, an horizontal or vertical Venturi (4), a nozzle (5) 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 (12). In order to stir the primary air flow passing through said coaxial conduit, a plurality of radial wings (10A) is arranged, said wings being shaped either planar or helical, and being connected on the outer surface of said gas supply conduit.Type: GrantFiled: December 4, 2008Date of Patent: March 6, 2018Assignee: Electrolux Home Products Corporation N.V.Inventors: Nico Biagioli, Piero Armanni, Marco Starnini
