Definitions

  • the present invention relates to an orifice unit for a burner, with an orifice and a support for the orifice, which has two side parts which carry the orifice and which are connected to one another by fastening means which serve to fasten the orifice unit in the burner.
  • CH-A-654900 shows an orifice unit which has an orifice formed as a circular plate with a central opening for the passage of air.
  • the cover with holder is provided with support legs that connect the cover with a socket that is used to fix the cover unit with a screw on the nozzle rod.
  • This aperture unit is not very stable.
  • the support legs are only connected to the front part of the socket, so that relatively small forces are sufficient to bend these support legs.
  • the need to attach the ignition electrodes to the screen also proves to be a disadvantage, since this makes it difficult to replace the ignition electrodes.
  • the known panel unit is relatively expensive to manufacture because the bushing is an expensive turned part and has to be connected to the support legs by a complex riveting operation.
  • an orifice unit in which the support legs are parts of a support which consists of two side parts which are connected to one another by two rings arranged at a distance from one another. The joints of the side parts with the cover and the rings are welded. A fastening plate is welded to one of the two parts of the step, which is used to fasten the ignition electrodes.
  • the panel unit When installing the burner, the panel unit is placed on the nozzle rod and clamped to it by a screw.
  • This panel unit consists of relatively cheap stamped parts.
  • the disadvantage is the relatively large production outlay.
  • the connections between the individual parts of the unit should be stable so that there is no risk of breakage. It would also be desirable if practically no follow-up inspection was practically necessary after production and the aperture unit could be manufactured largely automatically.
  • the fastening means are formed by a U-shaped bracket, the arms of which are arranged transversely to the longitudinal axis of the panel unit, and that one arm of the U-shaped bracket has at least one insertion opening on each side, in which a pin of the side part engages that each side part has at least one insertion opening into which a pin engages, which extends laterally outwards from the other arm of the U-shaped bracket, and that the cover is connected to the side parts. Since the arms of the bracket are arranged transversely to the longitudinal axis, the pins of the side parts engage practically parallel to the longitudinal axis in the insertion openings on one arm of the bracket.
  • the pins of the other arm of the bracket engage in the side parts transversely to the longitudinal axis of the diaphragm unit and thus prevent the pins of the side parts from being able to be moved out of the insertion openings of the first-mentioned arm.
  • the side parts are slanted slightly inclined outwards into the U-shaped bracket, then pivoted towards each other inwards so that the pins of the bracket engage in the insertion openings of the side parts, whereupon the resulting structure is fastened to the panel in a suitable manner.
  • This assembly can also be automated for large quantities. It is expedient if the side parts each have two pins which are arranged at a distance from one another and which engage in corresponding insertion openings on the arm. This results in a particularly stable arrangement.
  • the side parts of the panel unit according to the invention are not only with one arm but with both arms of the U-shaped bracket connected, which is used to attach the panel unit.
  • the side parts can therefore not be bent easily. There is therefore no risk that the orifice will be positioned eccentrically to the burner axis.
  • the U-shaped bracket can serve as a carrier for the ignition electrode. This makes it easier to replace them during service work.
  • the side parts advantageously have pins which can be inserted into the slot of the panel, with a fixation for example by twisting or riveting the pins.
  • the side parts can also be connected to the panel without welding.
  • the arms of the U-shaped bracket expediently each have an opening in the longitudinal axis of the burner, which serves to fasten the diaphragm unit in the burner.
  • the panel unit can be attached to the nozzle rod, the bearing for a rotating carburetor or a support.
  • the side parts expediently have a threaded hole into which a screw for fixing the panel unit can be screwed. The panel unit can be quickly and easily attached to the burner.
  • the side parts advantageously have angled wings. As a result, the side parts are deepened and, in addition, the dimensions of the panel support can be kept relatively small. There is also enough space to e.g. to attach the ignition electrodes to the carrier or to pass a fuel supply line past the carrier. It is expedient for the bracket to have a web with a threaded bore in order to fix the ignition electrodes. The screw with which the ignition electrode is attached is easily accessible, which makes it easier to replace the ignition electrodes during service work. In contrast to the known prior art, no additional holding plate has to be welded to one of the side parts.
  • Figures 1 to 5 show a panel unit 11 according to the invention, which consists of a panel 13 and a panel carrier 18 with two identical side parts 15 and a U-shaped bracket 17.
  • a U-shaped bracket 17 connects the side parts 15.
  • the bracket 17 has on one arm 19 insertion openings 23 into which the pins 27 of the side parts 15 can engage.
  • the other arm 21 of the bracket 17 has a pin 25 on the side edges, which engages in an insertion opening 29 on the side part 15.
  • the pins 27 are inserted into the insertion openings 23 and the side parts 15 are then pivoted against the bracket 17, so that the pins 25 also engage in the insertion openings 29.
  • the side parts 15 After the side parts 15 have been fixed to the panel 13, the side parts 15 are firmly connected to one another by means of the bracket 17 and thus form the panel carrier 18.
  • the side parts 15 have pins 33 (FIG. 2) which engage in insertion slots 35 on the panel 13. As can be seen from FIGS. 1, 3, 4b, c, the side parts 15 have angled wings 31. The pins 33, after they have been inserted into the insertion slots 35, are bent or twisted with pliers or a special tool fixed to the aperture 13. The panel unit can thus be assembled without adjustment, welding and inspection work.
  • the arms 19, 21 of the bracket 17 each have an opening 41, 41 ', which is used to fasten the diaphragm or baffle plate unit 11 in the burner.
  • the aperture unit 11 can be plugged into a nozzle rod or the like extending in the longitudinal axis of the burner by means of the openings 41, 41 'and then fixed by means of a screw which is screwed into a threaded bore 43 on the side part 15.
  • the web 37 of the bracket 17 connecting the two arms 19, 21 can be used to fix the supply lines necessary for the operation of the burner, e.g. the ignition electrodes.
  • the web 37 is designed as a fastening plate and has a threaded bore 39 for a screw (not shown).
  • the ignition electrodes which are surrounded by insulation, can be fixed directly to the panel unit using a holding plate.
