Definitions

  • the present invention relates to a light alloy gas burner, of the pipe burner type, for domestic cooking appliance, of reduced dimensions allowing its use for example in an extra-flat hob whose height of the built-in part does not exceed 30 mm (thickness of the worktop for standard kitchen furniture).
  • the pipe burners currently existing are generally made of cast iron or pressed sheet metal to resist the ignition of fire, but the imprecision in the realization of the venturi neck in one or the other of these manufacturing techniques does not allow to obtain an excellent centering, which limits the power of the burner to maintain an acceptable combustion hygiene.
  • the object of the invention is to remedy these drawbacks by producing a light alloy die-cast burner in which the temperature of the pipe is maintained at a value below the melting temperature in the event of ignition of the injector, ensuring good thermal conductivity of the connection between the pipe on the one hand and the hob box and the hearth plate on the other.
  • the subject of the invention is a low height gas burner in particular for an ultra-flat table comprising a housing of low height, such as a built-in hob, comprising a head connected to a pipe containing a venturi, characterized in that the pipe consists essentially of a tube arranged horizontally and terminated at a end by a curved wall intended to divert the gas flow towards an upper opening of the pipe on which the burner head is applied so that this opening is located inside the head, the pipe being in thermal contact with at least a wall of the burner housing which thus participates in the cooling of the burner pipe.
  • the burner comprises a pipe 1 consisting essentially of a tube arranged horizontally in a box 2.
  • the pipe ends in a curved wall 3 deflecting the gas mixture towards an upper opening 4 in communication with the head of the burner.
  • a collar 5 of low height (fig. 2) allows the fixing of the pipe on a hearth plate 6 closing the box 2 at its upper part, by means of screws penetrating into tapped holes 7 with interposition of an annular seal sealant 8 based on asbestos-rubber ensuring the tightness of the box so as to avoid on the one hand in case of overflow the flow of liquids in the box and on the other hand in the event of a door being closed oven possibly placed under the table, extinguishing the burner.
  • the horizontal tube of the pipe has two flats 10 (FIG. 3B) allowing a gain in the thickness of the box 2, leaving only a small space between the pipe and the upper and lower walls of the box.
  • the pipe 1 supports a burner head 9 delimiting the mixing chamber and a cap 11 pierced with the gas outlet orifices.
  • the burner head is placed directly on the upper opening of the pipe.
  • Each pipe is made integral with the box 2, for example by self-tapping screws using holes 12 in the ears 13 coming from molding with the pipe, the screw heads being housed in stampings 14 in the bottom of the box 2.
  • the horizontal end of the pipe has a bore 17 in which slides a tube 18 also made of light alloy and constituting the venturi.
  • This tube is provided with primary air inlet holes 19 and a groove 21 receiving an O-ring seal 22.
  • This seal is made of a material capable of withstanding a high temperature in the event of a fire (about 400 ° C.), for example made of silicone or fluorinated elastomer or other similar product resistant to the attack of combustible gases commonly used.
  • the dissociation of the venturi and the pipe is carried out in order to allow the change of the injector 23 screwed into a support 24 fixed to the casing 2 by means of a lug 25 and a nut 26 without dismantling the pipe.
  • FIGS. 3A and 3B represent respectively by an elevation view and a sectional view of a pipe comprising 6 fins 27 molded with the pipe.
  • FIG. 4 shows a perspective view of a pipe provided with a sole 28 molded from the pipe and made up of two elements connected to each of the two ears 13.
  • a hole 29 with notch 30 is used to house a spark plug (not shown) the notch allowing the passage of a supply wire without obligation to put it on all its length.
  • a threaded hole 31 formed at the end of the collar 5 is used for fixing a possible safety thermocouple.
  • the angular arrangement of the holes 29 and 31 is variable depending on the orientation of the burner pipe with respect to the axes of symmetry of the hob.
  • This type of burner can be used in all common gases with air adjustment by ring partially closing the orifices 19 or preferably by using injectors of geometry suitable for each gas according to a known process.
  • the curvature of the wall 3 of the pipe is chosen so as to avoid braking of the gas mixture.
  • a wall with a large radius of curvature is preferably used.
  • a horizontal pipe burner is obtained in which the burner head is placed directly on the horizontal body of the pipe, which makes it possible to produce a burner of minimum height.
