Definitions

  • This invention relates to a gas burner with several flame sectors.
  • Gas burner for food cooking are known.
  • double ring or triple ring burners and double burners are also available. These latter comprise two flame rings controllable separately by one or two gas feed taps.
  • FR-A-2.650.369 discloses a gas burner fixed to the hob surface of a cooker, the gas burner comprising two concentric flame sectors and two separate gas nozzles, each gas nozzle feeding a flame sector. Primary combustion air for the two gas nozzles and secondary combustion air for both flame sectors is drawn from the exterior of the cooker.
  • EP-A-0 485 645 shows a gas burner with two concentric flame sectors, each fed by a separate gas nozzle, wherein primary combustion air for the two nozzles is drawn from the interior of the cooker and secondary combustion air for both sectors is drawn from the exterior of the cooker
  • EP-A-0 525 299 shows a gas burner wherein primary air for the inner flame sector originates from the cooker interior and primary air for the outer flame sector originates from the cooker exterior. Secondary combustion air for both sectors is drawn from the exterior of the cooker.
  • An object of the invention is to provide a multi flame-ring gas burner having the advantages of known cup burners, while at the same time eliminating their drawbacks.
  • the gas burner of the invention comprises substantially a cup 2 and a body 4 external to the hob surface.
  • the cup 2 comprises a collar 6 provided with appendices 8 for the support and fixing of the sheet metal 10 which forms the cooker or hob.
  • the cup 2 is divided by a horizontal baffle 12 defining a chamber 13 which is lowerly provided with an aperture 14 closed by a removable cover 16.
  • the lower part of the cup 2 below the baffle 12 houses a gas feed conduit 18 provided with a nozzle 20 positioned horizontally and hence parallel to the sheet metal 10.
  • a primary air-gas mixing device consisting of a Venturi tube 22 divided downstream into two conduits 24 which then bend through 90° in a vertical direction to form two columns 26 positioned diametrically about the cup axis.
  • the chamber 13 of the cup 2 houses a second gas feed conduit 28 provided with a nozzle 30 of vertical axis.
  • the body 4 which rests on the cup 2 is connected to a discoidal element 31 provided centrally with a Venturi tube 34 facing the top of the nozzle 30 and supporting a substantially cylindrical flame divider 36 with lateral holes 38.
  • the body 4 is provided with pegs 41 inserted into the discoidal element 31 to form passage channels 35 for secondary air.
  • a flame divider 40 rests on the body 4 to define an annular chamber 44 provided with holes 42.
  • Two vertical conduits 32 cooperating with the cup columns 26 terminate in said chamber 44.
  • the gas burner of the invention operates in the following manner, reference being made to a single gas tap with two exit paths, it being however apparent that the burner can also be fed via two gas taps, one for each flame sector to be formed.
  • the gas quantity entering via the conduits 18 and 28 progressively decreases to hence reduce the flame power and dimensions.
  • This operation is at no stage affected by the streaming effect due to the opening or closure of a furniture or oven door located below the hob, which could cause air movement such as to interrupt the normal flow of primary air to the Venturi tube 22 and consequently cause the flames to separate from the holes 40 of the flame divider to the extent of extinguishing them.
  • the flame divider 36 at all stages remains fed because the primary air-gas mixture which feeds it is formed by the primary air 46 originating from above the metal sheeting 10, with the result that the flames leaving the holes 38 immediately re-ignite the mixture leaving the holes 42.
  • the effect of adjusting the burner to minimum flow has the effect of interrupting gas feed through the conduit 18, with consequent extinguishing of the flames leaving the holes 42.
  • the flame divider 36 is of small dimensions it enables a very low minimum flow to be maintained as the small gas quantity is distributed over a very small diameter.
  • the gas tap is again turned to allow the gas to enter through the conduit 18, with formation of a mixture which, as stated, emerges from the holes 42 an ignites by contacts with the flames leaving the holes 38.
