Definitions

  • the present invention relates to a gas burner, concretely of the type of those which are fed with a liquefied gas and which, normally, are installed on a bottle containing the liquefied gas, or by intercalation of a pressure reducer to obtain a low pressure of the gas domestic application, either directly on the same bottle.
  • the burners of the exposed type which are intended to heat what is known under the name of paella stoves, that is to say, the iron containers as a stove, shallow and with two handles, used to make the paella, are constituted by a special arrangement constituted by a tubular torus, single or double, which is provided with flame orifices on its upper zone and a radial connection tube, through a flexible pipe, to a bottle of liquefied gas.
  • the solution has been adopted to realize a large diameter and light weight burner allowing direct insertion into the regulator valve coupled to the bottle valve and providing adequate heat to the surface of the paella pan.
  • the construction of the burner was established by means of shaped pieces of sheet metal.
  • the gas burner object of the invention was developed, intended to be fed with a liquefied gas and suitable for being installed on a bottle containing the liquefied gas, characterized in that it consists of a single piece upper laminar shaped structure which is arranged integrally on another lower part, also of shaped laminar structure and of diameter equivalent to that of said upper part, the two upper and lower parts jointly forming a mixing chamber of the fuel gas with the oxidizing gas , so that, in its conformation, said upper piece has, on the one hand, a channel-shaped perimeter collar forming a concavity opposite said mixing chamber and which has its peripheral wall provided with outlet orifices fuel and seat mixture of the flames produced by the ignition thereof and, t, said upper piece has an upper central protrusion at reduced height disposed with its concavity oriented towards said lower piece, which lower piece has a lower central protuberance which is arranged with its convexity oriented towards the concavity of said upper central protuberance and which is
  • said upper and lower parts which are axially superimposed and which jointly configure said mixing chamber, are in perimetrically connected relation by said perimetral collar in the form of a channel of the upper part, and said tubular element is formed by a frustoconical socket with through which said gas burner is directly connected to the liquefied gas cylinder, said frustoconical socket having its smallest mouth within said mixing chamber so that said smaller mouth is at a very small distance from the concave face of the upper central protuberance.
  • said lower part has a substantially truncated conical configuration of reduced height, which, by its concave face, has in the center said lower central protuberance, which is frustoconical and of reduced height, and whose smaller base is configured in the form of annular, said lower part adopting on its periphery a mixed straight-curved-straight configuration, in which its rectilinear part configures a reduced cylindrical perimetric zone which extends in a collar, said collar serving as a seat and grip for said part higher.
  • said upper piece has a configuration in the form of a cylindrical wall cup of reduced height which, peripherally, extends in a dichromic collar which is differentiated into a first co-planar part with the base of said bowl and a second frustoconical portion which is provided with means for sitting and fixing on said collar of the lower part, said second frustoconical portion having on its surface said outlet orifices of the fuel mixture and seat flames.
  • said fuel mixture and fire seat outlet orifices have a unitary caliber globally balanced and they are evenly distributed in two rows on the surface of said second frustoconical portion of said dichromic collar of the upper part.
  • said lower piece punctually has eccentric protuberances for supporting the reverse of said upper piece.
  • the gas burner 1 is constituted by an upper piece 2 of shaped laminar structure which has a diameter greater than that which is usual in conventional burners of a domestic kitchen and which is arranged integrally on another lower part 3, also of shaped laminar structure, which has a diameter equivalent to that of said upper part 2.
  • the two upper and lower parts 2 and 3 jointly configure a chamber 7 for mixing the fuel gas with the oxidizing gas.
  • the upper piece 2 has, on the one hand, a perimetral collar 4 in the form of a channel which forms a concavity opposite the mixing chamber 7 and which has its peripheral wall provided with outlet orifices 5 of the fuel mixture and seat of the flames produced by the ignition of said combustible mixture and, on the other hand, said upper part 2 has an upper central protuberance 6 of reduced height arranged with its concavity oriented towards the lower part 3, which, at in turn, has a lower central protrusion 10 which is disposed with its convexity oriented towards the concavity of the upper central protuberance 6.
  • the gas burner 1 consists of a mixing chamber 7 configured between the two upper and lower parts 2 which are essentially discoidal and which are superposed axially and in relation perimetrically by the perimetral collar 4 in the form of a channel, of reduced height, of the upper part 2.
  • the perimetral collar 4 in the form of a channel, of reduced height, of the upper part 2.
  • the outlet orifices 5 of the fuel mixture arranged on the peripheral wall of said perimetral collar 4 in the form of a channel, it occurs the ignition of said combustible mixture in the form of a ring of flames.
  • the lower piece 3 has a central orifice 8 in which is fixed a frustoconical socket 9 in which occurs the suction of the air necessary for the fuel mixture by the action of the depression created by the gas emitted at pressure by an injector.
  • the burner 1 is connected directly with a bottle of liquefied gas, through said frustoconical socket 9 and a valve provided with a pressure reducer.
  • the smallest mouth of said frustoconical socket 9 is disposed inside the mixing chamber 7 so that said smaller mouth is at a very small distance from the concave face 6A of the upper central protuberance 6.
  • the lower part 3 has a substantially inverted frustoconical configuration of reduced height, which, by its concave face 3A, has in the center said lower central protuberance 10, which is frustoconical and of reduced height, and whose smallest base is configured in annular form 10A.
  • the periphery of said lower piece 3 adopts a configuration 3B of mixed straight section (curved-rectilinear), in which its rectilinear portion configures a reduced cylindrical perimetric zone which extends in a collar 11 serving as a seat and grip to the upper piece 2.
  • the upper part 2 has a configuration essentially in the form of a bowl which has a cylindrical wall 2A of reduced height which, peripherally, extends in a dichromic collar which is differentiated in a first co-planar portion 2B with the base 2C of said bowl and a second frustoconical 2D portion which is provided with seating and fixing means 12 on the collar 11 of the lower part 3 and which has on its surface the outlets 5 of the fuel mixture and seat of the flame of a fire crown.
  • Said outlet orifices 5 of the fuel mixture and flame seat have a unitary caliber globally balanced and are distributed regularly in two rows on the surface of said second frustoconical 2D portion of the collar of the upper part 2, the orifices 5 of the upper file being of larger diameter than the orifices 5 of the lower file.
  • the frustoconical socket 9 has openings 13 for sucking in the combustion air, and the lower part 3 has punctually eccentric protuberances 14 for supporting the cuff 2E of the upper part 2.
