Definitions

  • the invention relates to a device capable of reducing the number of microswitches usually used for the spark ignition of the gas burners of household cooking equipment.
  • this circuit there may be a special ignition button which comes into contact with the microswitches in series with the ignition plugs: this is located on the panel of the cooking equipment, independently of the knobs for the cocks, and the ignition is achieved by this being pushed down while the burner cock is opened at the same time.
  • cocks equipped with a microswitch are connected in parallel in the single electrical circuit which supplies all the igniter plugs.
  • the knob of the cock for the burner needed to be ignited is pressed, the relative solenoid valve to the burner opens while the microswitch, necessarily closes and, as in the case of a single button separate from the cocks, produces a spark from all the igniter plugs.
  • the microswitch is a separate element which can be mounted on the cock adapted to receive it.
  • the present invention in the case of household cooking equipment fitted with at least two gas burners supplied by means of corresponding cocks mounted next to each other and fitted with a spark ignition activated by means of microswitches attached to the said cocks, aims to allow the removal of one microswitch from each pair of adjacent cocks.
  • a further aim of the present invention is to achieve this objective by simply applying an additional mechanical element to the standard cocks manufactured according to the commonly-known technique.
  • aims are achieved through a device according to the present invention in which the ignition spark is produced, for at least one cock because the said cock is equipped with a striking element which comes into contact with the microswitch mounted either on a second cock or close to this latter or positioned between the two and, however, in such a way that the said microswitch can be activated by both the first and the second cock, each one independently of the other.
  • Figure 1 shows a frontal view, according to an embodiment of the present invention, of two adjacent cocks, both manufactured according to the commonly-known technique with the only difference that, on the first cock there is a spark ignition microswitch manufactured, mounted and activated according to the commonly-known technique, while the second cock does not have a microswitch but an additional mechanical element which can activate the microswitch of the first cock.
  • Figure 2 shows a further frontal view, substantially the same elements of the previous figure with only one variation relating to the additional mechanical element according to the present invention.
  • Figure 3 shows a top view of the same elements of figure 1 as well as the so-called 'ramp', i.e. the tubing which supplies the gas cocks: the ramp is omitted in the previous figures for the sake of clarity.
  • n o 1 denotes the gas ramp
  • n o 2 denotes the body of a standard gas cock designed according to the commonly-known technique
  • n o 2.b denotes a standard gas cock which can even be identical to the cock 2 except that it is fitted with an additional element according to the invention
  • n o 3 denotes the cylindrical flange by means of which either gas cock 2 or 2 .b can be coupled to the ramp 1
  • n o 4 denotes any of the knobs for gas cocks 2 or 2.b
  • n o 5 denotes the shaft of a knob 4
  • n o 6 denotes the body of a solenoid valve
  • n o 6.1 denotes the feeler pin of the solenoid valve 6 whose pressure enables the opening of the solenoid valve 6 itself
  • n o 7 denotes a microswitch mounted on a cock 2
  • n o 7.1 denotes the feel
  • the microswitch 7 is non incorporated in the cock 2 but simply mounted on this latter. If the knob 4 is pressed, the shaft 5 moves downwards and the striking element 8, mounted on to the shaft 5, crushes both the feeler pin 6.1 of the solenoid valve, opening it, and also the feeler pin 7.1 of the microswitch 7, if present.
  • the said striking element 9 makes it possible not to mount a microswitch 7 on either of the cocks 2.b adjacent to a cock 2.
  • the striking element 9 can be manufactured using any commonly-known material and technology and so it is not necessary to describe them.
  • a preferred embodiment envisages moulded plastic, of a suitable mechanical and thermal resistance, fitted with hooking teeth 9.1 with which the striking element 8 can be locked in place.
  • the said striking element 9 has a seating for coupling with the striking element 8 formed in such a way as to ensure the correct positioning of the first element with the second element, as the non-symmetrical positions of the teeth 9.1 show in the example in Fig. 3.
  • a striking element 9.a is envisaged comprising the striking element 8 with the end 9.2 added.
  • the material used will be the same as the material currently used to manufacture the striking elements 8. It could be advantageous, for production simplicity, to fit all the cocks 2 and 2.b., whether they are fitted with the microswitch 7 or not, with the same striking element 9 whose end 9.2, at the most, will not be used.
  • the present invention has been described applied to gas cocks designed to be installed in cooking equipment fitted with a horizontal panel, but it is clear that, with elements and mechanical means equivalent to those described, this could also be applied to many other household gas cooking equipment in which optional ignition microswitches are mounted on the cocks and they are accessible, for activation, from the outside of the body of the said cocks.
  • the said microswitch 7 mounted on a cock 2 cannot be accessed easily, because of its shape or position, by the striking elements 9 or 9.a mounted on a cock 2 .b, then the said microswitch 7 can be positioned between the two cocks 2.b, each one fitted with a striking element 9 or 9.a with the ends 9.2. in the appropriate positions, which can be identical if necessary.
