Definitions

  • the present invention relates to the burner sector for built-in tables, for kitchens and for heating appliances. It relates in particular to burners for ceramic hobs and for radiant heating.
  • Burners are already known for continuous cooktops, which consist of a chamber provided with a ceramic plate pierced with multiple holes; the combustible gas and the combustion air are introduced into such a chamber in which they mix and pass through the glass ceramic plate where combustion takes place. The significant heat produced is radiated to the ceramic cooking surface overhanging the perforated ceramic plate. The gases resulting from the combustion exit through a suitable conduit.
  • the first type of burner consists of a single mixing chamber, generally circular, in which there is a mixer-diffuser element in front of the gas and air inlet. This type of burner provides an almost unique amount of heat or between two relatively similar temperatures, obtained by regulating, within certain limits, the volume of gas introduced.
  • the second type of burner is made up of two concentric mixture, namely a circular and an annular provided with a single part or at least two parts of platinum in perforated ceramic.
  • This type of burner is provided with two separate nozzles and two venturi tubes which introduce the gas into the two chambers, thereby obtaining three levels of heat, namely minimum, average or maximum heat, depending on whether they operate the central burner, the ring burner or the two burners together.
  • This second type of burner is preferred to the first type because it gives the possibility of regulating the heat produced as required.
  • Two-zone burners more easily have drawbacks linked to a correct development of the combustion.
  • Such a new burner consists of two concentric circular chambers with a superimposed perforated ceramic plate.
  • the central chamber by means of an elbow connector.
  • a mixing and diffusing element Inside the chamber is a mixing and diffusing element; this element consists of a flat disc arranged parallel to the multi-hole plate, in front of the gas inlet.
  • the annular outer chamber has a part of its bottom having the shape of a small well placed opposite the associated venturi tube for supplying the gas.
  • a mixer-diffuser element constituted by a plate in the shape of a half-moon, of circular sector or the like, provided with holes of suitable shape.
  • Such an annular chamber is also provided with a venturi tube opening into the zone in the form of a small well.
  • the venturi tube can be connected to the small well-shaped area of the annular chamber by means of an elbow connection, as in the case of the central chamber, or alternatively it can be connected directly to a side wall of the small well shaped area. In the second case, the small well-shaped area is deeper.
  • the ignition and gas regulation are carried out by means of valves, thermostats, taps and suitable ignition electrodes, already well known.
  • the configuration of the external annular chamber, with the deeper small well and a horizontal inlet of the venturi tube makes it possible to significantly reduce the total height of the burner, which facilitates its installation on all types of kitchens and built-in tables.
  • Figure 1 In Figure 1 is shown a horizontal section (A-A) of the new burner while in Figure 2 is shown a vertical section (B-B).
  • the burner is composed of two mixing chambers, namely a central chamber 1 and an annular external chamber 2, chambers above which the ceramic plate 3 with multiple holes is disposed.
  • a tube forming a venturi 5 for the arrival of gas and air is connected, by means of an elbow connector 4, a tube forming a venturi 5 for the arrival of gas and air.
  • a mixing-distribution element 6 constituted by a small metal disc.
  • the annular chamber 2 has, on its bottom, a protrusion extending downward and similar to a small well 7. To this small well 7 is connected horizontally the tube forming a venturi 8 of gas and air inlet in the annular chamber 2.
  • the mixer-diffuser element 9 of the annular chamber 2, placed opposite the gas inlet, has a shape particularly studied for mixing and distributing the gas, in a uniform manner, over the entire annular chamber 2.
  • the element 9 can be provided with holes of variable size and variously distributed.
  • venturi tube 8 of the annular chamber 2 can also be provided with an elbow connection for vertically introducing the gas into the small well 7.
  • this small well 7 can have a shallower depth.
