    摘要： The present invention generally refers to a flame gas burner diffuser to be used in stove-type cooking equipments, more preferably in household stoves, comprising technical and functional features capable of improving the efficiency of exchanging heat with the bottom of cooking utensils. More particularly, said diffuser, according to the present invention, comprises a cup (1 ) provided with a surface (4) comprising an opening (2) at which a cooking equipment is accommodated, wherein over said surface (4) there is a series of barriers (3) duly arranged and positioned so as to form passage pathways and/or extended channels for allowing the hot gas flow generated by the burner flame to pass.

    摘要： A gas lighting device (1) including: a body (3) formed by an electrically insulating material carrying a plurality of high-voltage outputs (4) for the connection of spark generating means; a transformer (10) accommodated in the body and including a primary winding (11) wound around and carried by a ferromagnetic material core (12), a carrying element (14) formed by an electrically insulating material and designed to contain the primary winding (11) therein, and a secondary winding (15) consisting of a plurality of coils (16) externally carried by the carrying element (14), electrically insulated from the primary winding and essentially coaxial with the latter; the core (12) is ring-shaped on a plane parallel to an axis (A) of the windings (11; 15) and consists of two half rings (20,21) reciprocally coupled and arranged facing and closely adjacent to each other in the direction of the axis of the windings; a first circumferential portion (22) of the ring-shaped core, formed by one or both of the half rings, is accommodated inside the carrying element (14) so as to be surrounded by the windings (11;15), while a second circumferential portion (24) of the core is formed parallel to the first and radially on the outside of the windings so as not to be surrounded by the same.

    摘要： A gas heater has a burner, a porous body including two porous body blocks, an air supply/discharge fan, and an exhaust pipe opening/closing valve for selectively opening and closing an intermediary exhaust pipe which provides communication between one of the two porous body blocks, and an exhaust passage. When a capacity selector switch is shifted to a "high capacity" position, a controller opens the exhaust pipe opening/closing valve to heat both the porous body blocks with combustion exhaust gases from the burner, providing an effective heating area of a larger diameter on the upper panel. When the capacity selector switch is shifted to a "low capacity" position, the controller closes the exhaust pipe opening/closing valve to heat the other of the porous body blocks with combustion exhaust gases from the burner, providing an effective heating area of a smaller diameter on the upper panel.

    摘要： A gas heater has a burner including burner blocks disposed in confronting relation to an upper panel of glass, an air supply/discharge fan for supplying combustion air to the burner and discharging combustion exhaust gases from the burner through a porous body, and a branch air supply pipe opening/closing valve for selectively supplying and stopping supplying a mixture of a fuel gas and air to one of the burner blocks. When a capacity selector switch is shifted to a "high capacity" position, a controller opens a main gas valve and the branch air supply pipe opening/closing valve to burn the fuel gas on both the burner blocks, providing an effective heating area of a larger diameter on the upper panel. When the capacity selector switch is shifted to a "low capacity" position, the controller opens the main gas valve and closes the branch air supply pipe opening/closing valve to burn the fuel gas on one of the burner blocks only, providing an effective heating area of a smaller diameter on the upper panel.

    摘要： A gas heater has a burner disposed in confronting relation to an upper panel of glass and an air supply/discharge fan for supplying combustion air to the burner and discharging combustion exhaust gases from the burner through a porous body. The burner combusts a fuel gas at a predetermined air-fuel ratio which is determined to provide a good combustion efficiency of the burner to provide an effective heating area on the upper panel which is located within a circle having a larger diameter L10. Alternatively, the burner combusts the fuel gas at an air-fuel ratio representing richer air than the predetermined air-fuel ratio, lifting combustion flames off the burner. The lifted combustion flames are absorbed by the porous body to provide a smaller effective heating area on the upper panel which is located within a circle having a smaller diameter L20.
