Definitions

  • thermocouple known from DE 82 10 282 U1 and the ignition electrode of a pilot burner are the gas nozzle and the thermocouple in tubular approaches of a common carrier body used and with this screwed, while for the optional attachment of an ignition electrode in essential U-shaped spring clip, the two legs of which each have a recess for inserting the ignition electrode and at the ends of the legs into parts of the carrier body have engaging locking means.
  • One punched out of the center bar of the spring clip The tongue engages with its free end in a circumferential groove of the ignition electrode and secures them against falling out.
  • the invention is intended to hold the gas nozzle, flame baffle, thermocouple and Ignition electrode on a common carrier further simplified and the assembly of these components to be made a pilot burner.
  • This is achieved through the Claim 1 marked invention.
  • the Spring action of the tongues ensures that the individual components also Vibrations of the burner keep their position and do not loosen.
  • the simple assembly of the pilot burner is advantageous, in which the individual Components only through the corresponding receiving openings of the two leg plates need to be put through and the spring force of the one leg plate forming tongues are held resiliently.
  • thermocouple instead of a thermocouple, another flame monitoring sensor, for example a flame rod at the location of the thermocouple on the common support be attached.
  • a flame rod at the location of the thermocouple on the common support be attached.
  • the thermocouple or the flame rod can be omitted and the ignition electrode then serves at the same time as a flame rod.
  • Holding device can be used.
  • the common carrier for thermocouple 1, ignition electrode 2 and gas nozzle 3 with Flame baffle 4 consists of a substantially U-shaped angled one Spring plate. Its central web 6 has two fastening holes 7 with which the carrier 5 attached to a device or device frame, for example on a main gas burner can be.
  • the upper leg plate 8 (based on FIG. 1) there are three Push-through openings 9, 10 and 11 for the thermocouple 1, the ignition electrode 2 and the Gas nozzle 3 provided. You can, as shown in Figure 2b, either laterally offset from each other or, as shown in Figure 2d, in a row next to each other be arranged.
  • the lower leg plate 12 of the carrier 5 is in a plurality of tongues 13, 14 and 15 divided.
  • This lower leg plate 12 and its individual tongues also have Push-through openings 16, 17 and 18 through which the thermocouple 1, the Ignition electrode 2 or the gas nozzle 3 with their corresponding holding parts are pushed through.
  • the holding part 19 of the thermocouple 1 and the holding part 20 of the The ignition electrode 2 has a round cross section, while the holding part 21 of the gas nozzle 3 is designed as a hexagon. Other cross-sectional shapes of these components are also possible.
  • Each of these holding parts is provided with a circumferential stop collar 22, 23 and 24, on the underside of the upper leg plate 8 on the edge of the relevant Push-through opening 9, 10 or 11 abuts and is supported there.
  • thermocouple 1 and the ignition electrode 2 In the case of the thermocouple 1 and the ignition electrode 2, the force with which Holding parts 19 and 20 are held in the insertion position by the tongues 13 and 14 generated. They lie with the edge of their push-through openings 16 and 17 at the Holding parts 19 and 20 in frictional contact.
  • thermocouple 1 and Ignition electrode 2 For mounting thermocouple 1 and Ignition electrode 2 through the through openings 9 and 10 or 16 and 17 to inserted through to the stop collar 22 or 23. With their spring force, they tense Tongues 13 and 14 hold the holding parts 19 and 20 firmly in the push-through openings 16 and 17.
  • the gas nozzle 3 is attached in a different way.
  • the nozzle 3 near its upper edge a circumferential groove or collar 27 against which locking tongues 28 bent outward from the holding projection 25 of the flame guide plate lay.
  • the spring force of the locking tongues 28 presses the collar 27 off the upper leg plate 8 away and thus the stop collar 24 of the gas nozzle 3 against the underside of the upper Thigh plate 8.
  • the gas nozzle 3 is so with this top 25 to the upper Leg plate 8 locked.
  • the retaining lug 25 of the flame guide plate 4 is on its edge facing the upper leg plate 8 towards this leg plate open recess 29, in which one from the upper leg plate 8 in the direction of Flame baffle 4 engages spring tongue 30 pressed out and the retaining projection 25 and thus also secures the flame baffle against twisting.
  • Backlash 25 free of play To be able to put on the cylindrical part 26 of the gas nozzle 3, the holding approach is provided an axial slot 31.
  • the central web 6 is stiffened by two beads 32.
  • the carrier is made made of a single spring plate, which in the developed, that is flat form after punching, but before bending in Figure 2b or Figure 2d is shown.
  • the difference between these two representations is that in Figure 2d the Push-through openings 9 to 11 lie on a common center line 33, in the The tongue 30 also extends in the direction, while in Figure 2b the middle Push-through opening 10 for the ignition electrode opposite the common center line Push-through openings 9 and 11 are arranged offset and the spring tongue 30 opposite the center line 33 is arranged slightly rotated at an angle, so that the Flame baffle by the same angle with respect to the common center line 33 is twisted.
  • This angular offset can of course also in the opposite direction, i.e. in a clockwise direction, with the center of the push-through opening 10 then also is offset downwards with respect to the center line 33 (based on FIG. 2b).
  • thermocouple instead of a thermocouple, another, the Flame monitoring serving sensors, for example a resistance sensor or a Flame rod, are used in the carrier 5.
  • ignition and Flame monitoring uses the same element, namely an ignition electrode 2, which at flame monitoring also serves as a flame rod.
  • Shape and size of each Components determine the dimensions of the carrier 5 and its angled Leg plates as well as the shape and size of the through openings.
  • the lower Leg plate can, if only two components are to be fastened, in only two tongues be divided.
  • these tongues can all be in the same plane and not as in Figure 1 shown to be offset in height from each other.
  • FIG Figures 3 to 3c A possible embodiment of the flame baffle 4 and its retaining projection 25 is shown in FIG Figures 3 to 3c reproduced.
  • the lower part 25 of the hollow cylindrical Holding approach and its upper part 34 the actual, not shown in the drawing, but only forms a broken-off flame baffle.
  • the shape of the Flame baffle 34 since known per se, is not explained in detail here and cannot be arbitrary.
  • the tongues 28 are formed by punching out the sheet metal part 25.
  • the recess 29 is produced in that a tab 35 on punched out the lower edge 37 of the part 25 and, as shown in FIG. 3a, bends upwards.
  • the entire sheet 4 becomes one around the center line 36 Hollow cylinder bent until it takes the round shape shown in Figure 3.
  • the bent part 34 is angled obliquely to an obliquely in a known manner to form top-facing or horizontal-facing flame guide channel.
  • the gas nozzle 3 with the help of your cylindrical fastening part 26 and the collar 27 via the retaining projection 25 of the Flame baffle 4 and the spring tongue 30 braced with the upper leg plate 8.
  • the retaining lug 25 of the flame guide plate with the cylindrical Fastening part 26 of the gas nozzle 3 are welded.
  • the spring tongue 30 compared to the embodiment shown a little longer, so that it does not, as shown, push the retaining projection 25 away from the upper leg plate 8, but its end edge rests on the fastening part 26 with frictional force.
  • the gas nozzle 3 is when mounting from below with its fastener 26 through the opening 11 of the pushed the upper leg plate until its stop collar 24 on this leg plate 8 is present.
  • the spring tongue 30 engaging the fastening part 26 holds the gas nozzle in the inserted position so that it can no longer be pulled down.
  • the circumferential depression or groove 27 on the fastening part 26 is not required here.
