Definitions

  • the present invention relates to a gas burner for an apparatus for cooking, this invention being applicable in particular to tables of professional cooking.
  • gas burners "naked fire", essentially composed of a mixing tube, a body of burner and a burner cap.
  • the mixing tube ensures mixing air / gas necessary for combustion by "atmospheric induction”.
  • the body of the burner completes the mixing at the outlet of the mixing tube, ensuring the "relaxation” of the mixture before leaving.
  • the burner cap ensures the exit of the mixture and the diffusion of the flame, divided into a multiplicity of flame elements.
  • Gas burners of this kind are most often equipped also elements necessary for ignition and safety, plus particularly for flame presence monitoring. These elements are, in practice, a spark plug or pilot light and a thermocouple flame safety. These additional ignition and safety elements must of course be properly arranged, relative to the other components of the burner, so as to perform their functions, while being as far as possible protected, in particular with regard to defilements resulting from overflows from the contents of the containers placed on the burner. Indeed, these are sensitive elements that risk being out of balance or rendered inoperative by such defilement, and which in any case require, in the event of soiling, an awkward and risky cleaning itself to cause an adjustment, if it is accompanied by a dismantling of the elements concerned.
  • a first integration solution consists in carrying out burners in the shape of an annular pot, and to place the candle or pilot and / or the flame safety thermocouple in the recess center of this pot - see for example French patents 2,545,196, 2,570,804 and 2,594,214, as well as the English patents 1,348,245 and 1,543,618.
  • Japanese published patent application 61 119924 relates to also a gas burner of the latter type, in which a candle and a thermoelectric flame monitoring element are mounted on the same support block, positioned on the mixing tube.
  • the burner body has, at its periphery, notches in which are engaged respectively the spark plug and the element Thermoelectric. These elements are themselves covered by the hat of the burner.
  • such an embodiment only concerns a burner with direct ignition.
  • the French addition certificate 2 044 379 concerns, at contrary to the previous document, a gas burner with permanent pilot light, in which the same block carries a gas injector for the formation of a pilot flame, igniter and thermocouple for monitoring the pilot flame. These elements take place under the hat of burner.
  • the block is inserted into the burner body, which defines a clearance in which the igniter and the thermocouple take place, said block being fixed by screwing on a plate-shaped support.
  • the burner cap covers and protects the igniter and the thermocouple.
  • the burner configuration according to the certificate French addition 2 044 379 does not allow automatic burner shutdown, with the gas supply cut off, which poses a significant problem of security.
  • the present invention aims to remedy the drawbacks of various existing solutions, recalled above, providing a solution new applicable more particularly to burners with permanent pilot light, this solution integrating the ignition and safety functions in the head of the burner, in order to effectively protect all sensitive elements, facilitate cleaning of the assembly, and improve the reliability and safety of burner operation.
  • the invention essentially relates to a gas burner for a cooking appliance, the burner being a permanent pilot and being composed of a mixing tube, a burner body and a cap burner, and also fitted with a spark plug and a thermocouple flame safety, the spark plug and the safety thermocouple flame being mounted on a common support block, positioned on the tube mixer and under the burner body, this body having at its periphery at minus an opening in which is engaged, or through which appears part of said support block, which support block has on its face upper three through holes, namely a vertical axis orifice supply of gas mixture to form a pilot flame, an orifice constituting a housing covering the spark plug and an orifice constituting another housing, receiving the safety thermocouple of flame, which monitors the presence of the pilot flame, characterized in that the support block has a recess, hollowed out on its upper face and opening on the outside of this support block, in that the three orifices above of the support block are provided in the recess of this support
  • the invention is thus characterized by the addition of a component, can be designated as "safety ignition block” or “pilot block and safety”, which is positioned in the continuity of the mixing tube and under the burner body, and which has a particular configuration.
  • the external part of the support block considered, engaged in the peripheral opening of the burner body, is located in continuity with the outer edge of the burner body.
  • the support block being normally partially covered by the upper part of the burner body, the gas mixture leaving through the corresponding orifice will be "channeled" horizontally to the outside of the block, then will “go up” on the periphery of the body to lick the face lower edge of the burner cap, starting point of the flame diffused by the burner cap.
  • the gas burner shown as a whole in Figures 1 and 2, consists of a mixer tube 1, bent in shape, a body of burner 2 of frustoconical shape under which the mixing tube 1 terminates, a burner cap 3 of circular shape surmounting the body of burner 2, and an ignition and safety block 4, positioned on the mixer tube 1 and under the burner body 2.
  • the ignition and safety block 4 clearly visible in Figures 3 and 4, has a recess 5 hollowed out on its upper face, and opening out on the outer side of this block 4.
  • a recess 5 In the recess 5 are formed three through holes 6, 7 and 8, with vertical axes.
  • the first port 6 is in communication, by an internal channel (not shown) of block 4, with the mixing tube 1; it is used here for the supply of the gas mixture necessary to feed a pilot flame permed.
  • the second orifice 7 located a short distance from the previous one, serves housing for a spark plug 9 which is used to ignite the gas mixture leaving through the first orifice 6, in order to form the flame pilot.
  • the third port 8 located a short distance from the two previous, serves as a housing for a flame safety thermocouple 10, which monitors the presence of the pilot flame.
  • the burner body 2 has at its periphery an opening 11, shaped as a notch or notch, in which the part is engaged exterior 12 of block 4, i.e. its part furthest from the axis central burner. As shown in particular in Figure 1, this part outside 12 of block 4, engaged in opening 11 of burner body 2, is located in the continuity of the outer edge 13 of this burner body 2.
  • the annular upper part 14 of this body 2 overcomes block 4, in particular in the region of recess 5.
  • the flaming mixture exiting through the orifice 6 arrives under the part upper 13 of the burner body 2, and it is "channeled" to the horizontal towards the outside of block 4 before “going up” to the periphery body 2 to finally lick the base of the burner cap 3, starting point of the flame elements starting from this cap 3.
  • the block 4 is entirely uncovered. If the pilot flame is not extinguished beforehand by the user, this flame will come out vertically orifice 6, and will no longer lick the flame safety thermocouple 10. The latter will then cut off the gas supply to the burner, preventing thus the possible ignition of the gas mixture if a request for unfortunate heating occurred, even before the burner body 2 and the burner cap 3 are replaced.
  • the housing of the block 4 under the burner body 2 protects the spark plug 9 and flame safety thermocouple 10, carried by this block 4.
  • Figure 5 shows another embodiment of the burner to gas.
  • the opening 11 formed in the burner body 2 here has a reduced extent, and does not reach the outer edge 13 of the body 2.
  • the block ignition and safety 4 is practically not engaged in the opening 11, but it is flush with said opening, and remains visible through this opening 11.
  • block 4 is even better integrated and protected under the burner body 2, while ensuring its functions.
