Abstract: A gas cavity burner, wherein the present invention discloses a burner applied to ovens, more specifically, the present invention discloses a tubular burner composed by two half-shells disposed superposed conforming an inner mixture and diffusion chamber the receives a comburent and a combustible in order to generate a pilot and primary flames, said two half-shells comprising substantially symmetrical perimetral surfaces wherein one said shell comprises a corrugated perimeter surface while the other comprises a flat perimeter surface, the burner of the present invention also presenting a spacer between both half-shells, in that said spacer reduces deformation issues caused by the heating, while it also brings more control to the pilot flame and aggregates a reduction of material thickness in the manufacturing of the burner.

Abstract: A method of operating a cooking zone (2) of a cooking appliance (1). The method includes determining an actual temperature value representative of an actual temperature of an item (6) to be heated; determining a power level (I) set on a user control device (3); and calculating a rectified power level (II) based on the actual temperature value, the actual power level (I) and a preset setpoint temperature. The rectified power level (II) is configured to remove differences between the actual temperature value and setpoint temperature and the rectified power level (II) is indicated on a user display (9, 4).

Abstract: A method of operating a domestic cooking hob (1, 3), wherein the cooking hob (1, 3) includes a user control interface (4) adapted to inputting user control information for controlling operation of the cooking hob (1, 3). The cooking hob (1, 3) is operable in a safety locked operational mode. In the safety locked mode, the cooking hob (1, 3) triggers a safety action in case that a person tries to operate the control interface (4) without unlocking the cooking hob (1, 3) or a person comes closer to the cooking hob (1, 3) than a preset distance without unlocking the cooking hob (1, 3).

Abstract: 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.

Abstract: Gas burner provided with a plurality of concentric circular flame crowns, with a burner body apt to be mounted on the surface of a cooking plate, a burner body apt to be mounted on the surface of a cooking plate and provided with a first chamber for the diffusion of the air/gas mixture, and whose top is closed by a first cover, a second outer annular burner surrounding said central burner, a first gas inlet in communication with said body, a first gas injector able of injecting a gas flow into a respective Venturi pipe to said first central burner, a second gas inlet in communication with said body, wherein said second annular burner is provided with two separate diffusion chambers, and whose top is closed by a second cover, wherein said second gas inlet is in communication with said two separate chambers which are not in communication to each other, two distinct injectors connected with said second gas inlet and placed on the same end position of said second gas inlet, two respective horizontally oriented Ve
