Definitions

  • US-A-5 323 759 discloses a cooking hob according to the preamble of claim 1.
  • the gas burners of this known cooking hob are placed entirely on the superposed structures defining the cooking hob.
  • the usual burners comprise an injector carrier arranged between (substantially flat) superposed structures defining the cooking hob.
  • the injector carrier is fixed to at least one of these structures by screws.
  • the injector carrier also supports the usual spark plug or similar ignition means for generating the flame by triggering combustion of the gas leaving a usual diffuser secured upperly to the injector carrier and provided on the upper structure of the cooking hob.
  • said injector carrier is connected to a usual feed conduit for the gas to reach said diffuser.
  • US-A-4 354 478 discloses a cooking hob in which, for each gas burner, it is necessary to use a pair of bolts fixing the burner to the base wall of a box casing.
  • the injector carrier is secured to the superposed structures of the cooking hob. This is achieved by fixing elements which fix the injector carrier to the lower structure of said hob and at least one screw for fixing the injector carrier to the upper structure of said hob. Because of the shape of said burner part and of the described structures, the said fixing is difficult to achieve on mounting the cooking hob.
  • known injector carriers do not allow easy, reliable and fast connection to the gas feed conduits connected to it.
  • An object of the present invention is to provide a burner which represents an improvement over known burners.
  • a particular object of the invention is to provide a burner of the stated type, the injector carrier of which can be quickly and securely fixed to the cooking hob structure, which can be safely fixed to the gas feed conduit, and which supports the corresponding spark plug in such a manner as to protect it and its connection to the high voltage generator in the case of electricity discharge in the absence of the flame diffuser.
  • a burner comprises an injector carrier 1 with a substantially cup-shaped body 2 flanged along its edge 3. Laterally, the body 2 comprises a tubular cylindrical projection 4 for connecting the injector carrier to a conduit 5 for feeding gas to an injector (not shown) to be positioned in a seat 7 provided in the centre of the body 2.
  • the tubular projection projects partially from a lower wall 10 of the base 11 of the body 2 in which, within this latter, there is provided said seat 7.
  • a further projection 23 having a height (from said wall) equal to the height of the projection 4.
  • the fixing means 14 and the projections 20 have heights (from the wall 10) greater than the heights of the projections 4 and 23.
  • the element 21 is arranged to cooperate with a corresponding recess (not shown) provided in the structure 15.
  • Each fixing means 14 and that projection 20 which follows said fixing means in the anticlockwise direction along said ideal circumference are arranged to cooperate with an arched recess or slot 30 having a widened end 31.
  • the slots 30 allow simple connection of the injector carrier 1 to the structure 15.
  • the fixing means 14 are arranged in the ends 31 of the slots 3 ( Figure 4).
  • the body 2 is then rotated in the direction of the arrow F of Figure 2 (ie in the clockwise direction in the illustrated embodiment) so that in each slot 30 the corresponding fixing means 14 are brought to the other end 33 of the slot, distant from the end 31 ( Figure 6).
  • the raised part 20A of that projection 20 which follows the means 14 penetrates into the end 31 to lock the rotation of the body in the opposite direction to the arrow F.
  • the injector carrier 1 hence remains fixed to the lower structure 15 of the cooking hob.
  • the body 2 also comprises a seat 40 for a screw 41 which fixes the upper structure 16 of the cooking hob.
  • This seat is formed in a portion 42 of the body 2 which projects from its edge 3 towards the injector seat 7.
  • the injector carrier 1 also comprises a seat 45 for a spark plug 46.
  • This seat is formed in the flange 3A of the edge 3 and comprises a frusto-conical portion 47 projecting upwards from this latter and open at 48 on one of its sides.
  • the usual electric cable 49 connecting the spark plug 46 to a usual high voltage generator (not shown) passes through this opening.
  • the spark plug is then locked in said seat 45 by a substantially U-shaped elastic element inserted into a seat 51 lying in a plane perpendicular to the axis W of the seat 45.
  • the portion 47 protects a large part of the spark plug body 46A and can receive any electrical discharge emitted by the spark plug in the absence of the usual flame diffuser. In this manner, said discharge or spark is discharged to earth (via a connection between the body 2 and earth, not shown) without it damaging said high voltage generator.
  • the projection 4 on the body 2 receives by simple insertion the end 5A of the conduit 5, about which there is positioned an O-ring 55 inserted in a seat 56 in said projection.
  • the conduit 5 is simply inserted into the projection 4 and is retained therein by the shape of the conduit 5 itself.
  • this latter comprises two parallel portions (5A and 5B), the first connected to the body 2 and the second fixed to a known gas feed source in which there is located a usual valve 57 controlled by a known knob or tap 58.
  • the burner with an injector carrier as described is advantageous for use on a cooking hob and provides considerable safety in use against electrical discharges generated by the spark plug if the flame diffuser has been removed from the injector carrier.
  • the burner is easy to connect to the gas feed conduit.
