Definitions

  • This invention concerns an improved gas cooker burner with three concentric flames, and precisely of the type with flame dividing member in a single piece.
  • At least one of the burners intended to be used with the cooking containers of greater diameter, is preferably provided with multiple concentric flames, typically three, to improve the distribution of heat on the bottom of the container itself and thereby have a greater cooking efficiency.
  • This can be achieved with burners and relative flame dividers dismountable into several pieces, but presenting in such a case drawbacks caused by the poor maintenance practicality and the difficulty in obtaining a satisfying level of cleanliness of the pieces themselves.
  • burners have been used with three concentric flames or crowns obtained by two rings in a single piece, but with two separate gas deliveries on the inner ring and the outer ring, separately controlled by two different gastaps or even a single gastap which controls the gas feeding to the outer ring only from a certain level of opening of the delivery onwards, while for reduced supplies the gas flows only from one of the rings or crowns, usually from the innermost one.
  • gastaps which controls the gas feeding to the outer ring only from a certain level of opening of the delivery onwards
  • it proves to be particularly difficult to achieve an even distribution of the gas in the different members which give rise to the concentric flames, so as to have both an exact balancing of the pressures and an adequate flow of secondary air by the different flame areas, while assuring the propagation and preservation of the flame itself, without the presence of frequent flame separation phenomena.
  • the object of this invention is to provide a burner of the above-mentioned type which is free from the aforesaid faults and drawbacks, since it may be fed by a single gas delivery with a single control tap and therefore has a single spark-plug and a single safety thermocouple. In this way the flames spread immediately from the ignition point on the outer crown all the way to the innermost one and there remain, with no flame separation, even for reduced gas delivery, controlled by a single gastap quite similar to the conventional ones for single flame burners.
  • a burner comprising a basic distributing body, connected to a gas delivery tube of known type and having three radial gas passage areas and three intermediate secondary air inlet areas, with a flame dividing member, fit to be placed on said distributing body, comprising two concentric rings connected by three radial members fit to form the cover of the above-mentioned gas passages, with intermediate apertures for the secondary air, the inner ring having on its periphery two staggered rows of holes one on top of the other as well as are present on the surface confronting the latter on the inner periphery of the outer ring, whose outer periphery has other two series of holes one on top of the other and level with the latter a single spark-plug and a thermocouple connected to a known-type gas safety valve are provided.
  • the burner according to this invention fed by the outlet 10a of a gas delivery tube 10 of conventional type, is formed by a body 1 of the real burner upon which a flame dividing member 2 is placed, as it generally occurs in the known single flame burners.
  • the body of the burner 1 serves the purpose, particularly important in this case, of properly distributing the gas, or rather the mixture of gas and primary air fed by the tube 10, to the different flames of the member 2.
  • the body 1 has radial passages 3 communicating with a central hole 5 coaxial with 10a, and separated one from the other by the raised walls 7 defining the vertical passages 9, therefore perpendicular to the plane of the body 1, for the entry of the secondary air by the central flames.
  • the passages 3, as shown in fig.1, are preferably ,three, as well as the secondary air inlet areas 9.
  • the flame dividing member 2 in a single piece according to the invention, substantially includes an outer ring 4 and an inner disc 6.
  • the three flames rise from proper holes on the outer and inner periphery of the ring 4, as well as on the outer periphery of the disc 6.
  • the outer ring 4 and the inner disc 6 are connected by radial connecting members 8, coinciding in number and position with said passages 3 of which they define the upper wall or closing cover.
  • the holes on the flame divider 2 through which the gas comes out and by which the flame is formed, are shown in greater detail.
  • the holes on the inner crown 6 are indicated by 12 and those on the outer ring 4 by 14 and 16, on the inner and outer side respectively. All the holes are preferably oriented upwards and particularly those indicated by 12 and 14, on confronting surfaces, are directed one against the other so as to produce converging gas flows, thus meeting in an intermediate position, substantially along a circumference having its diameter included between that of the central crown 6 and the inner diameter of the ring 4.
  • all the holes 12, 14 and 16 are arranged as two series of holes one on top of the other, which are staggered by the two inner flames in order to make the reciprocal preservation of the flame easier, in that the lower row of holes, alternating with the upper ones, gives rise to the so called "pilot light” which ignites and supports the flame on the upper row of holes, or vice versa.
  • the gas flow is directed radially outwards, as already said before, while the flame spreads inwards starting from the external spark-plug 11.
  • the gas has a higher pressure, consequently their diameter will be smaller than that of the holes 14 and even smaller compared to the outer holes 16.
  • a projecting ledge 18 is provided, capable of reducing this pressure and the occurrence of this phenomenon.
  • each hole 16a is preferably vertically aligned with an upper hole 16 for which it acts as pilot light, as besides is known in prior art.
  • the secondary air for the outer flame reaches the holes 16 and 16a with no particular problems, but this is made easier by a preferred shape of the worktop 20, which forms a raised area 21 on which the burner body 1 is mounted, so that between the latter and the surrounding top remains a space of some millimeters, suitable to make the passage of the secondary air easier, especially in the inner part through the ducts 9.
  • thermocouple 13 is single too and controlled by the existence of the outer flame, which presupposes the presence of the two innermost flame crowns too.
