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 burner for use in cooktops including a lower body, a top cap closing said lower body on top, two coaxial flame rings having the same diameter, but extending at two different heights, a single gas injector, a single Venturi tube, and a single expansion chamber for the gas issuing from said single Venturi tube, said chamber being adapted to supply said two flame rings of the burner. The burner further including a first cylindrically-shaped hollow annular member adapted to be applied vertically upon said lower body, and a second substantially planar hollow annular member adapted to be applied upon said first annular member and support said cap. The lower flame ring is supplied with gas from said expansion chamber via a plurality of ducts arranged within said first cylindrically-shaped annular member. Said two flame rings are provided with gas outlet ports having same or similar cross-section areas.

Cooking top with improved gas top burner

The invention provides a gas burner () with a high power burner unit and a low power burner unit.

Gas burner

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 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.

The present invention concerns a burner assembly that includes a burner body having a combustible gas chamber from which a combustible gas is distributed to a plurality of burner ports at which the combustible gas can be combusted and a stability chamber in gas-flow communication with the combustible gas chamber for maintaining the combustion of the combustible gas in the stability chamber whenever the combustion of the combustible gas at the plurality of burner ports is disturbed, whereby the combustion of the combustible gas at the plurality of the burner ports may be resumed upon the cessation of the disturbance. The burner assembly can also include a burner cap for closing off the top of the burner body so as to substantially preclude the escape of the combustible gas from the combustible gas chamber, the stability gas chamber and the burner ports at the top of the burner body.

Burner with flame stability

The present invention refers to a double burner for gas cookers, of the type provided with multiple concentric flame crowns (FE, FC), which comprises two gas inlet () that reach the centre of the body () at a slightly different height, so that communication can be provided between the gas inlets, if necessary, by simply drilling a hole () with vertical axis from the upper inlet () to the lower inlet ().

Double burner for gas cookers, of the type provided with multiple concentric flame crowns

The present invention refers to a gas burner crown for kitchen hob, of the type with a radial series of notches, composed of shallower notches alternated with deeper notches, which act as small burner nozzles, from which small radial flames originate; the crown is characterised by the presence of eight regularly spaced angular sectors with shallower radial notches.

Gas burner crown for kitchen hobs

An oven door includes a peripheral frame, an internal transparent pane adhesively secured to the frame and an external transparent pane releasably mounted on the frame. The frame has lower and upper rims formed with openings for the circulation of air through an interspace between the two panes. A profile member is secured to the upper rim of the frame and has a central handle. The profile member has an internal cavity communicating with the openings of the upper rim and with the interior of the oven chamber. First deflector elements within the internal cavity direct a flow of air from the interior of the oven into the interspace. Second deflector elements within the cavity define venturi-type passages for facilitating the escape of air from the interspace.
