Definitions

  • a gas burner in which a centrally arranged gas inlet opening leads horizontally into a narrow, high annular gas space.
  • the annular gas space rises obliquely upward on its underside from the gas inlet opening to the opposite side.
  • the annular gas space is open at the top and is covered by an annular burner circuit.
  • the annular configuration of the gas space, a gas-free inner region (mounting area) is formed, which is completed by using an inner burner up to seal the gas burner against external influences.
  • a thermocouple and a spark plug are usually attached.
  • This gas burner has the disadvantage that the gas / air mixture flowing in through the gas inlet opening essentially hits the almost vertical side wall of the narrow gas space in a frontally direction. As a result, a part of the gas / air mixture is reflected back towards the gas inlet opening, resulting in a pressure drop and a poorer Primär Kunststoffansaugung.
  • a gas burner in which the gas inlet takes place through an eccentrically arranged gas inlet opening, which merges laterally directly into an annular gas space.
  • the gas / air mixture flows in a substantially straight line into the annular gas space, but results from the one-sided circulation an uneven gas distribution to the upward gas outlet.
  • a gas-free interior mounting area is formed to seal the gas burner against external influences and to include an internal burner, a thermocouple and a spark plug.
  • WO 2006/117815 A1 discloses a double burner for gas hobs with multiple concentric burners, comprising five Venturi mixing chambers, namely a central clamp with a vertical axis feeding a central burner and four evenly spaced oblique axis clamps feeding an outer annular burner.
  • WO 2005/073630 A1 discloses a gas burner comprising: a distribution means having at least one distribution chamber for distributing a gas / air mixture around the distribution chamber, the burner having a plurality of flame openings through which the gas / air mixture can pass and be ignited; at least one injector associated with the manifold arranged to inject gas directly into the manifold chamber through a vent formed as a vertically oriented channel, an orifice, and at least one venturi disposed adjacent to the manifold Opening adjoins. Also disclosed is a distributor for one.
  • a gas burner the manifold having a top wall and a bottom wall spaced by a sidewall to define a cavity therebetween, the manifold having means for securing at least one injector to a manifold with the gas / air Supply, and an inlet opening to allow connection with a Gasversargung, which can pressurize the cavity, wherein the upper wall and the lower wall are formed of relatively thin areas.
  • GB 2 223 302 A discloses a burner for a gas hob having an outer and optionally an inner burner assembly.
  • the outer burner assembly has a mixing tube feeding an annular chamber from which inner and outer annular outlets as well as inner and outer rings of holes extend.
  • the inner burner assembly has its own mixing tube and has both an annular outlet and a ring of holes.
  • the gas burner has a gas inlet opening leading into a gas inlet space, the gas inlet space rising at least partially obliquely from the gas inlet opening into a gas space with disk-shaped basic shape, wherein the gas space is intended to distribute gas penetrating through the gas inlet opening, and the gas space is upwardly opening, arcuate gas passage chimneys for discharging the gas has penetrated through the gas inlet opening and distributed in the gas space gas.
  • the gas flowing through the gas inlet opening is only slightly reflected at the gas space or gas inlet space, so that thereby no pressure drop occurs.
  • the gas space itself can be made comparatively flat with sufficient distribution of the gas / air mixture, since it no longer depends on the height or position of the gas inlet opening, the gas flow must not be performed circumferentially.
  • the gas space at least in supervision, has a disc-shaped basic shape, since then in the Compared to the annular gas space at the same volume a much flatter design is possible, and also the gas can spread over a large area in the gas space, which allows a more uniform gas distribution.
  • the gas space has a variable height, in particular if the gas space has a partial gas space which is curved upwards above the gas inlet space.
  • thermocouple and / or a guide for a spark plug possibly in the form of a common guide, are guided through the gas space, and not by a gas-free mounting space, there an adverse annular configuration of the gas space can be avoided.
  • the gas burner 1 has a gas inlet opening 2, which leads into a gas inlet space 3.
  • the gas inlet space 3 rises at least partially by means of an inclined bottom wall 4 into a gas space 5 arranged above the gas inlet space 3.
  • the gas space 5 is of disc-shaped basic shape.
  • an inner burner 6 and the receiving portion 7 are integrated for a thermocouple and a spark plug.
  • the gas space 5 opens up in the form of arcuate gas passage chimneys 8.
  • a burner ring (not shown) can be placed, which surrounds an inner combustion chamber with the inner burner 6 and at the outer periphery of a main flame is generated.
  • the gas space 5 may have a different height h. It is flat compared to the prior art, d. h., That its maximum diameter D is greater than its maximum height h.
  • the gas space 5 has a centric partial gas space 5a, which is curved upwards above the gas inlet space 3. Gas flowing from the gas inlet opening 2 into the gas inlet space 3 is conducted through the inclined surface 4 into the gas space 5 without significant pressure loss.
  • the gas flow from the gas passage chambers 8 is substantially evenly distributed, since the mecanicbrennerwandung 6a begins in the upper region of the sloping bottom wall 4 and the passage openings 10, the receiving area 7 and the central partial gas space 5a are arranged so that the gas flow without large pressure loss in the remaining gas space 5 distributed and from the Gas joshoffskaminen 8 can flow out. This deflection reduces the pressure loss of the gas stream, resulting in a higher flow rate of the gas stream and thus a higher primary air intake result, which in turn has better combustion properties result, see also FIG. 1 . 3 . 4 . 6 )
  • FIG. 2 shows the gas burner 1 from FIG. 1 from below with the gas inlet opening 2 for the main flame or the outer circle, the inclined bottom wall 4 of the gas inlet space and a further gas connection 9 for supplying the internal burner and through holes 10 for guiding the spark plug and thermocouple.
  • the sloping bottom wall 4 and thus the gas inlet space 3 widen at least partially laterally from the gas inlet opening 2 to the gas space.
  • FIG. 3 shows a plan view of the gas burner 1 from FIG. 1 along a section line A of FIG. 1 , Analogous to FIG. 2
  • the oblique bottom wall 4 and thus the gas inlet space 3 widens from the gas inlet opening 2 to the gas space 5.
  • the gas space 5 is of disk-shaped basic shape and diverges therefrom only on recesses 11 in the side wall 12 for the purpose of circumventing screw holes 13.
  • the accommodating portion 7 for the thermocouple and the spark plug have the respective through holes 10 and are integrally formed with the inner burner 6.
  • FIG. 4 shows a sectional view in side view analogous to FIG. 1 along the section line BB FIG. 3 , In this view, one of the through-holes 10 is shown in the accommodating portion 7 for the spark plug and the thermocouple, respectively.
  • FIG. 5 shows a sectional view in side view analogous to FIG. 1 along the section line CC off FIG. 3 , in which the disc shape of the gas space 5 is clearly visible.
  • FIG. 6 shows a view of the gas burner FIG. 1 along a section line DD FIG. 1 with the three Gas screen trecskaminen 8, the centrally disposed inner burner 6 and the through holes 10 for the spark plug and the thermocouple.
  • the invention is not limited to the embodiment shown. So flow baffles can be used, for. B. in case of deviations from the laterally central arrangement of the gas inlet opening. Also, the gas inlet space may be shaped differently, in particular the inclined bottom plate and / or the shape of the lateral expansion. Thermocouple and spark plug can also be performed outside the gas space.
