Definitions
- This invention relates to a gas burner with several flame sectors.
- Gas burner for food cooking are known.
- so-called “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.
- An object of the invention is to obviate these drawbacks by providing a multi flame-ring gas burner having the advantages of known cup burners, while at the same time eliminating their drawbacks.
- Figure 1 is a plan view of the burner cup
- Figure 2 is an axial section through the burner on the line ll-ll of Figure 1
- Figure 3 is an axial section therethrough on the line Ill-Ill of Figure 1.
- 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 It is also apparent that in the illustrated example the gas flow through the conduit 18 is greater than the gas flow through the conduit 28
- the gas tap When the gas tap is in its maximum open position corresponding to maximum gas burner power, the gas enters through the conduits 18 and 28, and in particular - the gas which enters through the conduit 18 and leaves from the nozzle 20 enters the Venturi tube 22 to draw in a large quantity of primary air 50 from below the metal sheeting, to consequently achieve good mixing and hence high power with good combustion
- the primary air-gas mixture advances along the conduits 24 and columns 26 to enter the annular chamber 40 via the conduits 32 From this chamber the primary air-gas mixture emerges through the holes 42 to burn using secondary air originating from above the cooker for its combustion,
- the gas which enters through the conduit 28 and leaves from the nozzle 30 enters the Venturi tube 34 to draw in primary air 46 from the top of the metal sheeting 10
- the primary air-gas mixture hence reaches the holes 38, from which it emerges to burn using the secondary air 48 originating from above the metal sheeting 10 and passing through the channels 35
- 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.
- the nozzle 20 can be easily and quickly changed because of the access offered to the chamber 13 by the removability of cover 16, which is fixed to the wall 12 by a screw 48,
