Definitions

  • the invention relates to a nozzle arrangement for a gas burner that can be used in gas hobs, with a gas supply pipe, a mixing pipe, and a nozzle and a gas chamber.
  • the object of the invention is to maintain the advantages of the two systems, but to avoid their disadvantages.
  • the gas feed pipe which extends into the region of the gas burner carries in its end section an attached gas nozzle which in turn carries the mixing pipe upstream of the gas burner flame region.
  • the mixing tube has a mixing chamber which acts as an injector and is arranged upstream of the mixing tube towards the gas nozzle.
  • the mixing chamber of the mixing tube is placed on the gas nozzle; the mixing tube is connected to the gas burner feed tube designed as an expansion tube or is combined with the latter.
  • At least one air slot is arranged in the mixing chamber of the mixing tube, so that the gas emerging from the nozzle combines with the air stream flowing in through the air slot and mixes in the mixing chamber, this mixture then flowing into the burner capsule through an expansion tube that widens toward the gas burner .
  • the jacket of the gas supply pipe is sealed off from the gas nozzle. It is not necessary to seal the mixing chamber from the nozzle, since a vacuum is created when the gas escapes from the nozzle.
  • the mixing chamber of the mixing tube can be connected to the gas nozzle by means of known fastening elements.
  • the nozzle arrangement according to the invention is simple in its design and thus inexpensive to manufacture, and operational reliability is also guaranteed.
  • the gas nozzle 2 is located on the gas pipe 1.
  • the gas nozzle 2 has a narrow outlet channel 3.
  • the gas flows in the direction of the arrow 4, the gas entering a mixing chamber 5 and flowing upwards there. Air is sucked in through a fresh air opening 6 and mixes with the gas in the mixing tube 7.
  • the gas / air mixture now flows through the expansion tube 8 to the flame tube plate 9 and then through the flame tube nozzles 10 in the flame plate 11, and burns on ignition.
  • the expansion tube is expanded at 12 and thus forms a seat for the flame plate 9; instead of widening, a pin can also be provided.
  • the mixing chamber 5 snaps onto a collar 14 of the gas nozzle 2.
  • a pin 15 connects the mixing chamber 5 to the gas nozzle 2.
  • a seal 16 serves to seal the gas nozzle from the gas supply pipe 1. The pin 15 is guided closely through the gas nozzle 2, so that there is no fear of gas leakage. A negative pressure prevails in the mixing chamber as a result of the gas flowing through, so that fresh air is drawn in through the fresh air opening 6 and the risk of gas leakage in this area is eliminated.
  • the ends 19 of the pin 15 according to FIG. 2 are used as guide cams for a bayonet catch.
  • the mixing chamber 5 is here with a groove 20 Mistake.
  • the groove 20 is cut into the mixing chamber wall of the mixing chamber 5, the collar 14 of the nozzle 2 being designed as a key hexagon, in such a way that the mixing chamber 5 can be pulled onto the pipe 1 sufficiently tightly. Arrange hexagon on the mixing chamber 5.
  • the mixing chamber 5 can also be attached to the gas nozzle 2 in a different manner, as shown for example in FIGS. 4 and 5.
  • the gas supply pipe 1 is curved and has a bulge collar 18.
  • a bracket 17 formed from spring steel is inserted with its ends 17 'into bores of the mixing chamber 5 and the nozzle 2, an arcuate central section of the bracket 17 below the bulge collar 18 comprising the gas pipe 1 and connects this to the gas nozzle 2 in a form-fitting manner via the bulge collar 18.
  • Fig. 5 shows that instead of the pin 15 according to Figures 2 and 3, the bracket 17 in the region of its ends 17 'can be used as a bayonet fitting for fastening the mixing chamber 5 on the gas nozzle.
  • FIG. 6 shows an enlarged partial view of the sealing area circled in dash-dot lines in FIG. 4 with the pipe end 1 and the attached nozzle 2.
  • the seal 16 according to FIG. 4 is placed in the region of the bulge collar 18 in such a way that the nozzle is sealed off from the pipe 1.
