Definitions

  • the invention relates generally to the field of gas burners called "internal flame", that is to say whose flames converge at a point of heat concentration.
  • the invention relates to a gas burner internal flame, comprising a gas injector, a vacuum tube, or venturi, ensuring induction primary air, a pot, and a cap, the cap styling the pot and delimiting jointly with the pot an annular chamber for distributing a mixture air and gas fuel, the chamber having a internal edge that surrounds the center of this room and which is pierced with flame outlets, and the vacuum tube with an open air inlet atmospheric, first and second sections longitudinal profiles respectively converge and diverge, and an outlet leading into the annular chamber, the first section taking birth at the entrance of the tube, the second section succeeding the first section and ending at the outlet of the tube, and the injector being relatively more closer to the inlet of the vacuum tube than the exit from this tube.
  • Gas burners such as those fitted traditionally cooktops and professional stoves are designed so that the combustible mixture is allowed in the room annular by an upward movement, and belong the type of burners called "external flame", in which the flames diverge radially towards outside.
  • Burners of this type inherently have interesting properties in terms of power modulation dynamics, energy efficiency, and loss reduction calorific, the modulation dynamics being represented by the ratio of the greatest flow likely to be achieved while retaining a hygienic combustion and a flame stuck to the orifice outlet, at the lowest flow rate likely to be reached without flashback in this orifice exit.
  • the invention aims to provide a self-designed internal flame burner by compared to internal flame burners, and therefore free limitations attributable to these.
  • the gas burner of the invention by elsewhere conforms to the generic definition given by it the preamble above, is essentially characterized in that the vacuum tube extends longitudinally along a substantially inscribed axis in a median plane of the annular chamber, and in this that this tube has a length at most equal to double the greatest distance from the edge internal chamber of the center of this chamber.
  • the burner of the invention despite its very small footprint, has excellent performance.
  • the internal edge of the annular chamber is for example circular, the length of the tube then being at most equal to the diameter of the internal edge of the chamber, or even at most equal to the radius of this internal edge.
  • the tube opens into the chamber in a direction radial with respect to the internal edge thereof, and this room is equipped with a distribution baffle of the combustible mixture, shaped in an arc of a circle and interposed between the outlet of the tube and some at least flame exit ports arranged opposite this exit.
  • This chicane advantageously occupies part only from the height of the room, and is arranged closer to the hat than the pot.
  • the outlet of the tube has respectively, in the midplane and perpendicular to the median plane, a width and a height, the height being less than the width.
  • the second section of the tube present, perpendicularly in the median plane, a substantially constant height up to the exit of the tube.
  • the second section of the tube and the chamber can then present, perpendicular to the median plane, substantially equal heights.
  • the gas burner of the invention can also include a device for holding the injector, itself including a gas inlet pipe, a plate, and a bracket, the injector being mounted at a free end of the gas inlet pipe, the plate being integral with the vacuum tube and having a opening opposite the entry of this tube, and the stirrup being integral with the plate and supporting the conduit gas inlet remote from the opening of the platinum.
  • a device for holding the injector itself including a gas inlet pipe, a plate, and a bracket, the injector being mounted at a free end of the gas inlet pipe, the plate being integral with the vacuum tube and having a opening opposite the entry of this tube, and the stirrup being integral with the plate and supporting the conduit gas inlet remote from the opening of the platinum.
  • the injector preferably opens into the first section of the vacuum tube.
  • the vacuum tube can be formed of two substantially symmetrical parts of each other by relation to the median plane of the annular chamber.
  • the invention relates to a internal flame gas burner.
  • such a burner comprises a gas injector 1, a vacuum tube 2, a pot 3, and a cap 4.
  • the vacuum tube 2 also called “venturi” has for role of ensuring a primary air induction of combustion, this induction of air, or aspiration, resulting from the depression caused in tube 2 by the gas leaving the injector 1, and accompanied by turbulence by which the primary air mixes gas.
  • the cap 4 covers the pot 3 and delimits, jointly with this pot 3, an annular chamber 5 whose edge internal 51 surrounds the center 50 of this chamber, and has 510 flame outlet ports.
  • the vacuum tube 2 has an inlet 20 open to atmospheric air, a first longitudinal section 21, a second longitudinal section 22, and an outlet 23 opening into the annular chamber 5.
  • the first section 21 starts at entry 20 of the tube 2 and has a converging profile.
  • the second section 22 succeeds the first section 21, has a divergent profile, and ends at the exit 23 of the tube.
  • the injector 1 is arranged at a larger near the inlet 20 of the vacuum tube 2 than the outlet 23 of this tube.
  • the vacuum tube 2 extends longitudinally along an X axis which is substantially contained in the median plane P of the annular chamber 5.
  • this tube 2 has a length L2 which is at most twice the greatest distance R separating the internal edge 51 of chamber 5 from the center 50 from this room.
  • the length L2 of the tube 2 is therefore at most equal to twice the radius R of this edge internal 51, i.e. the diameter of this same edge 51.
  • the tube vacuum 2 opens into chamber 5 along a radial direction with respect to the internal edge 51 of this room.
  • the bedroom 5 is equipped with a baffle 6, shaped as an arc of circle and interposed between the outlet 23 of the tube 2 and those of the flame exit ports 510 which are arranged opposite this outlet 23.
  • the baffle 6 is for example fixed to the cap 4 (figure 4) and in any case preferably arranged closer to the hat 4 as pot 3, this chicane occupying only one only part of the height H5 of the room.
  • the width L23 of the outlet 23 of the tube 2 that is to say the dimension presented by this output 23 in the median plane P of chamber 5, is greater than the height H2 of this outlet 23, that is to say at the dimension of outlet 23 of tube 2 perpendicular to the median plane P of chamber 5.
  • the width L23 of the outlet 23 of the tube 2 is almost twice the height H2 of this exit.
  • the second section 22 of the vacuum tube 2 can have, perpendicularly at the median plane P, a substantially constant height up to the outlet 23 of the tube, and therefore equal to the height H2 of this outlet 23.
  • the height H2 of the second section 22 of the tube 2 ( Figure 4) is advantageously equal to the height H5 of bedroom 5.
  • the internal flame gas burner of the invention further includes a device 7 for maintaining injector 1, this device itself including a gas inlet duct 71, a plate 72, and a stirrup 73.
  • the injector is mounted at the free end 710 of the gas inlet pipe 71, this pipe being maintained by stirrup 73.
  • the plate 72 is integral with the vacuum tube 2 and presents, opposite the inlet 20 of this tube 2, a 720 opening which promotes air circulation primary in tube 2.
  • the stirrup 73 which is integral with the plate 72, supports the gas inlet pipe 71 away from the opening of the plate 72, thus releasing this opening to further promote air circulation.
  • the injector 1 opens into the first section 21 of the tube depression 2, very close to the connection area of first and second sections.
  • the vacuum tube 2 is advantageously formed of a stack of two parts 2A and 2B, these two parts can therefore be substantially symmetrical one of the other with respect to the median plane P of the room ring finger 5.
