Definitions
- the main subject of the present invention is a improved gas burner to equip a table cooker, stove, or the like.
- Cooktops or stoves are the most often equipped with several open flame burners.
- Each burner generally includes a head connectable to a gas inlet pipe and consisting essentially of two removable parts, know a base covered by a hat for define a room from which the gas at the periphery of the head to provide a so-called main flame, capable of heating a container placed above the burner head.
- pilot flame is produced under the main flame to ensure good combustion stabilization for all distributed gases, good flexibility in adjusting the power and good ignition of the main flame.
- pilot flame gas burners currently known present a number disadvantages in the pilot flame.
- the flow of flame gas supply driver is most often defective due to gas leaks occurring at the interface of the parts stacked forming the burner head.
- This flow of uncontrolled gas in the supply of the pilot flame therefore has the effect of disturbing the combustion at the level of the main flame which located above the pilot flame.
- the flame pilot is therefore disturbed and, by way of Consequently, the main flame also.
- the object of the present invention is in particular to solve this problem by proposing a gas burner improved in that the flow of gas supplying the pilot flame will always be controlled and will confer so at this flame an optimal regularity and therefore likely to provide good stabilization at the main flame.
- the invention relates to a gas burner perfect for hob, stove or analogous, and of the type comprising a head which is composed a base comprising a central part constituting the entry of the air-gas mixture in the head, from a hat and a spacer interposed between the base and the hat on the one hand define with the hat a first chamber from which gas can escape orifices formed at the periphery of the head between the spacer and the cap, to produce a flame main, and on the other hand define with the base a second bedroom communicating with the first chamber and from which gas can escape through a peripheral slot formed between the free edge of the spacer and the base to give birth to a pilot flame under the main flame, characterized in that said spacer comprises a center opening with dropped edge which is mounted at sliding on the central part of the base and which just fits into the bottom of an annular groove formed in the base around said central part so as to create the peripheral slit producing the pilot flame.
- the spacer extends in its plane beyond the edge fallen above to form a crown supported on the central part of the base.
- spacer and / or the base are provided with bosses or the like opposite the aforementioned peripheral slot.
- the spacer is also provided with centering pins of the hat on said spacer.
- the base, the spacer and the cap constituting the head of the burner may have a circular shape or else a star shape with at least three branches.
- Figure 1 is a half view in axial section of a head gas burner according to the prior art.
- Figure 2 is an axial sectional view of a burner to gas in accordance with the principles according to this invention.
- Figure 3 is an exploded view and partially in section of the burner head shown in the figure 2.
- Figure 4 is a half view in axial section of another embodiment of the burner according to this invention.
- FIG. 5 is a schematic perspective view of another form of burner head using the principles of the invention.
- a known gas burner head which consists of a base 1 closed by a cap 2 and comprising a part control unit 3 in the form of a portion of duct capable of to communicate with an entry (not shown) of the air-gas mixture to supply the defined chamber 4 by the base 1 and the cap 2.
- the gas in chamber 4 will exit through orifices 5 formed in the periphery of the cap 2 which has generally a circular shape and this so give birth to an illustrated main flame schematically in 6. Hat 2, below the orifices 5, still has a plurality of other smaller orifices 7 through which the gas will pass for give birth to a pilot flame shown schematically at 8, and this after passing through a baffle 9 formed between the base 1 and the cap 2.
- the present invention in particular overcomes these disadvantages in planning, as seen on Figures 2 and 3 a substantially flat spacer and circular 10 interposed between the base 1 and the cap 2.
- This spacer 10 defines with the cap 2 a first bedroom, namely bedroom 4, capable of give birth to the main flame 6 as we will describe in detail later.
- the spacer 10 also defines with the base 1, of the other side, a second chamber 11 for distributing the gas communicating with the first chamber 4 thanks to a plurality of calibrated orifices 12 formed in said spacer.
- This chamber 11 will allow a gas flow controlled likely to give rise to flame pilot 8, as will be described in detail later.
- This peripheral slot 13 results from mounting by sliding and interlocking of the spacer 10 on the central part 3 of the base 1 which, as seen well on figure 2, is connected to a system venturi 14 upstream of which is provided a gas 15, so as to supply the chamber 4, and also the chamber 11 via calibrated orifices 12, with a suitable air-gas mixture.
- the spacer 10 has in its center a opening 16 with dropped edge 17.
- This fallen edge 17 can be slidably mounted on the central part 3 of the base which has a shape of revolution ensuring the centering of the spacer 10, as can be seen in FIG. 2.
- the dropped edge 17 is housed in an annular groove 18 provided in the base 1 and externally concentric with the central part 3.
- the fallen edge 17 of the central opening 16 in the spacer 10 will come to fit at the bottom of the groove 18, so as to create the peripheral slot 13 producing the pilot flame 8.
- the base 1 may include at its periphery, and opposite the spacer 10, a extra thickness 19 on which will be supported bosses or the like 20 provided on the underside of the spacer 10, as seen in Figures 2 and 3.
- calibrated orifices 12 have a diameter greater than 2 mm so that allow their realization other than by recovery mechanical.
- hat 2 As for hat 2, it has on the underside, and as known per se, a crown of slots 22 of so as to form, by pressing on the spacer 10, as much orifices for the passage of the air-gas mixture producing the main flame 6.
- cap 2 can perfectly, without departing from the scope of the invention, to be whether or not integral with the spacer 10.
- the crown of slots 22 could be provided on the periphery of the upper face of spacer 10, instead of being provided on the underside hat 2 as seen in Figure 3.
- the embodiment of the burner illustrated by the Figure 4 differs from that described above, only in that the spacer 10 extends next its plan, and in the direction of opening 16, beyond the fallen edge 17.
- the projecting annular part of the spacer 10 will somehow form a crown 23 able to bear on the annular face upper 3a of the central part 3 of the base 1.
- the base 1, the spacer 10 and the cap 2 constituting the head of burner have a substantially circular shape, but, as we can see in figure 5, we could perfectly apply the invention to a head of three star burner branches 24. This means that each of the above elements constituting the burner head would have the form of a three-pointed star.
