Definitions

  • the invention relates to a gas hotplate burner of the kind comprising a gas nozzle fitted into the bottom part of a burner body assembly, a supply passage for primary air, preferably taking the form of a circular slit, a mixing venturi, a crown structure defining a chamber, and a cap structure providing a lid for same.
  • Burners based on the principle of a cap covering a crown being a circular array of openings for the gas mixture burning on the outside of the crown are known as is the use of a short venturi which has the advantage that the mixing takes place in a short vertical distance as opposed to the traditional long venturi. This enables a low profile of a cooker arrangement, which is particularly suitable for fitting into existing cupboards without wasted space.
  • a larger amount of gas per time unit i.e. a larger diameter nozzle or injector for the same pressure, and this calls for more primary air in order to obtain the correct gas/air mixture. This is traditionally obtained by means of a larger supply passage for primary air.
  • a further advantageous embodiment is particular in that the crown and cap define a ring-shaped chamber as well as a central circular chamber, flame openings being available on the outside perimeter, on part of the inside perimeter, and on the outside of the central circular chamber.
  • the cap will be in two parts, one predominantly ring-shaped, the other a central disc. This construction allows increasing the performance of a burner of a given diameter by about 80%.
  • a further advantageous embodiment is particular in that an electric ignition device is fitted in a cut-out in the crown close to the outside perimeter, said cut-out having an outwards directed flame opening directed at an angle towards the ignition device which lights the outwards directed flames and an inwards directed flame opening which lights the inwards directed flames .

  • Fig. 6 shows the ignition system for a burner such as that shown in Figs . 4 and 5.
  • gas G is provided to an injector i which directs a jet of gas upwards and pulls in fresh air A from peripheral openings .
  • the gas is mixed in the venturi structure constituted by the vertical part Vv and a horizontal part Vh which an expanding cross section as the gas/air mixture travels outwards between the cap Ca and the conical surface of the crown Cr.
  • the gas/air mixture burns at the outside edge of the crown shown at FI and F2 as well as at the inside at F3.
  • the flames FI, F2 (which in reality is a complete circle of flames surrounding the crown Cr) use the surrounding air as the source of secondary air, and the flames F3 (which in reality form parts of a circle of flame) use air "scooped" up from the indraught of primary air by means of a scoop S .

  • Fig. 6 is shown how the ignition device E functions in the burner according to the invention.
  • the gas When the gas is turned on it creates a combustible gas/air mixture in the space M, and it flows out through all the flame openings, both outwards and inwards.
  • two particular flame openings are provided, II being directed towards the active part Ea of the ignition device which ignites the exiting gas, creating the ring of flames FI, F2.
  • the other particular flame opening 12 is directed towards the inside and the gas is ignited by the first flame at II, whereafter it ignites the inner ring F3 of flames which in their turn ignite the central ring F4.

Abstract

Traditionnellement la puissance d'un brûleur à gaz comprenant une couronne et un chapeau est en rapport avec son diamètre, c'est-à-dire sa circonférence. La présente invention concerne un brûleur comprenant non seulement des flammes périphériques mais également des flammes près centre. Cette caractéristique est obtenue grâce à une structure de couronne et chapeau spécifique et une alimentation d'air secondaire pour les flammes dirigées vers l'intérieur, cette alimentation étant réalisée à l'aide d'une plaque (S) de prise d'air qui prélève une partie du flux (A) d'air primaire alimentant le brûleur. On obtient ainsi un brûleur présentant une puissance sensiblement accrue par rapport aux brûleurs traditionnels de diamètre égal.
