Definitions

  • the present invention relates to a dual gas burner, in particular of the type supplied with a liquefied gas and suitable for being installed on the tank containing the liquefied gas, making it possible, by virtue of its dual burner condition, to supply heat to containers, ranging from small diameter containers, such as pots and coffee makers, to larger diameter containers, such as casseroles and paella pans, with simultaneous use of both burners for larger diameter containers .
  • Kitchen appliances of the type that mate directly to the mouth of a liquefied gas cylinder normally have a single burner which, generally, is reduced diameter.
  • one of the burners of the latter comprises two or more crowns of fire, usually simultaneous, although in some cases they may be independent.
  • burners are made of metal cast iron and, in general, they have a high weight that makes them unfit to be incorporated into the hobs or cookers of the type that are located directly on the mouth of the liquefied gas cylinder.
  • a double gas burner of the type indicated at the beginning has been developed, characterized in that it is constituted by the combination of an upper laminar body of circular plane and a lower laminar body, also of circular plane. , which conform between them a central chamber and a tubular peripheral ring which have flame orifices located on their peripheral walls and in the centrifugal direction, laite central speaker and said tubular peripheral ring receiving the gas supply of the can, once the pressure-conditioned gas by means of a pressure reducer, through a distribution valve which is provided with an on-off valve, said distribution valve selectively and / or simultaneously sending gas to said central chamber, through a frustoconical sleeve with a Venturi effect provided with orifices for the intake of oxidant, and with said tubular peripheral ring, through a conductive bent radial elbow provided with oxidant inlet ports.
  • the assembly formed by said upper and lower laminar bodies is supported on said dispensing valve through a bucket having its convexity directed towards said dispensing valve to form a seat thereon, said bucket extending perimetrically by a seat collar for said assembly, the center of said bucket having an orifice for positioning said frustoconical socket and a series of orifices for the passage of air to the surface said assembly through openings provided between said central chamber and said tubular peripheral ring.
  • said peripheral walls of the central chamber and the tubular peripheral ring are configured according to frustoconical surfaces.
  • said dispensing valve is constituted by a body which, by a lower part, has means for coupling it to the mouth of a liquefied gas cylinder and an inlet pipe for the fuel gas at the pressure of the canister, said duct being controlled by said on-off valve which allows access of the gas to said expander, so that once packaged at reduced pressure in said expander, the gas is contained in a pressure gas chamber conditioned from which two outlet pipes lead to two corresponding passage valves which in turn control the passage of the flow rate of the pressurized gas to the central burner constituted by said central chamber and to the peripheral burner constituted by said tubular peripheral ring , the corresponding injectors or nozzles being arranged in the outlet pipes to said burners.
  • said on-off valve is constituted by a shutter which fits snugly into the cylindrical inside of a tubular appendix of the body of said dispensing valve, said shutter being urged by a spring which applies it stably against a seat of the gas inlet pipe to said on-off valve, the latter pipe being located at the bottom of said tubular appendix and in communication with the outlet mouth of the canister, means being arranged to overcome the spring and locate the shutter in a stable opening position, and said shutter seat being accompanied in said bottom by the gas outlet port to said expander.
  • a preferred embodiment of the dual gas burner which is the subject of the present invention is that represented, in its external aspect, on the Figures 1 and 2 .
  • the double gas burner 1 is constituted by the combination of an upper laminar body 2 of circular plane with a lower laminar body 3, also of circular plane, which conform between the two a central chamber 4 and a tubular peripheral ring 5, which have flame orifices 6 which are located, respectively, on the peripheral walls 7 and 8 of said central chamber 4 of said tubular peripheral ring 5 and in the centrifugal direction.
  • Said central chamber 4 and said tubular peripheral ring 5, as shown in FIGS. Figures 3 and 4 receive the gas supply of the canister, once the pressure is conditioned by means of a pressure reducer 9, through a distribution valve 10 which is provided with an on-off valve 11 and which selectively sends and / or simultaneously the gas to the central chamber 4, through a frustoconical socket 12 with Venturi effect with orifices 13 for the combustionant inlet, and to the tubular peripheral ring 5, through a bent radial duct 14 provided with orifices 15 of oxidizer inlet.
  • the Figure 5 shows the arrangement of the components of the double burner, in which the assembly formed by the upper and lower laminar bodies 2 is supported on the dispensing valve 10 through a cup 16 having its convexity directed towards the dispensing valve 10 to constitute a seat on it.
  • the bucket 16 extends perimetrically by a seat collar 17 for said set of upper laminar bodies 2 and 3 of circular plane.
  • the bucket 16 has in its center an orifice 18 for the positioning of a frustoconical sleeve 12 and a series of orifices 19 for air passage to the upper surface of said assembly, through an annular opening 20 provided between the central chamber 4 and the tubular peripheral ring 5 of said assembly.
  • the dispensing valve 10 consists of a body which at a lower part has means 21 for coupling to the mouth of a tank of liquefied gas and a pipe 22 for entering the combustible gas. the pressure of the tank.
  • the pipe 22 is controlled by the on-off valve 11 which allows access of the pressurized gas to the pressure reducer 9.
  • the gas is contained in a gas chamber 23 with a pressurized pressure from which two outlet pipes 24 and 25 leave. to two corresponding passage valves 26 and 27 which in turn control the passage of the conditioned gas flow to the central burner constituted by the central chamber 4 and to the peripheral burner constituted by the tubular peripheral ring 5.
  • outlet pipes 28 and 29 to the burners are arranged the corresponding injectors 30 and 31.
  • the on-off valve 11 is constituted by a shutter 32 which passes neatly into the cylindrical interior of a tubular appendage 33 of the body of the dispensing valve 10, said shutter 32 being urged by a spring which stably applies against a seat of the gas inlet pipe 22 to said valve from the cylinder.
  • the pipe 22 is located at the bottom 34 of said tubular appendix 33 and is in communication with the outlet mouth of the canister.
  • Lever means 35 are provided to overcome the spring and locate the shutter 32 in a stable open position.
  • the closure seat is accompanied by the outlet port 36 of the gas to the expander 9.
  • the Figure 5 also illustrates that the peripheral walls 7 and 8, respectively, of the central chamber 4 and the tubular peripheral ring 5 are configured in frustoconical surfaces.
  • the double gas burner 1 has a support grid 37 for the containers to be heated.
