Definitions

  • the invention relates to gas radiation burners according to the preamble of claim 1.
  • Radiant gas burners are used in particular on glass ceramic cooktops with several cooking zones. Under each cooking zone there is a burner plate corresponding to its size, below which there is a gas-air mixing chamber. The combustion gases are discharged laterally between the glass ceramic cooktop and the burner plate.
  • gas radiation burners are described in DE 195 45 842 CI and DE 196 37 666 AI and EP 0 638 771 Bl.
  • the burners have mixing chambers and mixing tubes of different sizes.
  • the mixing chambers are formed by sheet metal pots, which are manufactured with tools by pressing, pressing or deep drawing. Accordingly, for the required torch sizes can be provided for each own tool, which increases tool costs and complicates logistics and assembly.
  • the burner plate consists of a high-temperature-resistant, highly porous material, on the surface of which burns a flame carpet that heats up the burning surface so high that it radiates and radiates the radiant heat to the cooking zone.
  • the burner plate can consist of a perforated ceramic material. Such a burner plate I described, for example, in DE 198 47 042 AI.
  • the object of the invention is to simplify the structure of gas radiation burners of the type mentioned at the outset in such a way that an adapted mixing chamber size is not necessary for each burner plate size.
  • the structure described is compact, which facilitates the adaptation to different desired cooking zone designs of the glass ceramic cooking surface.
  • the size of the base burner is preferably adapted to the smallest burner plate provided.
  • the gas-air mixture outlet from the mixing chamber takes up an approximately circular area on.
  • Adaptation collar is an adaptation of the gas-air mixture flow to a larger or smaller or differently shaped, for example oval or angular, burner plate. In the room at the bottom of that
  • Gas-air mixture outlet and is limited at the top by the burner plate and laterally by the adapter collar, the gas-air mixture is distributed over the burner plate.
  • the gas-air mixture outlet and the burner plate do not have to be concentric with one another. If an eccentric structure is desired for structural reasons, a largely uniform gas / air mixture can nevertheless be applied to the burner plate by means of an appropriately shaped adjustment collar.
  • the burner can also be used in applications that are not in the cooking area, for example in boilers, fireplace inserts, ceiling spotlights, process heating ovens, etc.
  • FIG. 1 shows a gas radiation burner in supervision
  • FIG. 2 shows the gas radiation burner in a side view
  • 3a shows the base burner of the gas radiation burner in side view
  • FIG. 3b its bottom view
  • Figure 5 is a plan view of three differently sized gas radiation burners under a hotplate.
  • a gas radiation burner 1 has a base burner 2, an adaptation collar 3, a burner plate 5 held on a base plate 4 and an exhaust gas duct 6.
  • the base burner 2 consists of a mixing tube 7 which opens into a mixing chamber 8. Fuel gas is introduced into the mixing tube 7 via a nozzle 9, which draws in ambient air via an air adjustment element 10. The gas-air mixture leaves the mixing chamber 8 at an essentially circular gas-air mixture outlet 11 and is guided by means of a spiral guide plate 25, the disturbance being evened out and slowed down.
  • the mixing chamber is covered by a perforated distribution plate 12. At a distance a from (see FIGS. 3a, 4) the distribution plate 12, the flat burner plate 5 is arranged approximately parallel to the latter. The clearance between the distribution plate 12 and the burner plate 5 is closed laterally by the adjustment collar 3.
  • the adjustment collar 3 and the base plate 4 consist of a metal plate.
  • the mixing chamber 8 and the distribution plate 12 are individual parts.
  • the burner plate 5 lies at its edge on a step 13 of the base plate 4 and is held thereon by means of a retaining ring 14 or other holding elements.
  • the retaining ring 14 or the other element can be part of the
  • the burner plate 5 consists of a highly porous, temperature-resistant material.
  • it is a perforated ceramic plate or a ceramic fiber mat, as is known on the market under the Schott Ceramat brand.
  • a ceramic fiber mat consists of a self-supporting, coated, perforated fleece made of ceramic fibers.
  • the burner plate 5, when embodied as a ceramic fiber mat, has, for example, a perforation with a hole diameter of approximately 1.4 mm and a hole spacing of 2.8 mm in approximately 60 staggered rows.
  • the burner plate 5 can be circular, oval or angular.
  • a component 15 which forms the exhaust gas duct 6 and which partially surrounds the burner plate 5 and is open to the exhaust duct 6 is seated on the base plate 4.
  • the component 15 consists of a microporous thermal insulation material, for example of vermiculite or a mixture of vermiculite and ceramic fiber material, or generally of ceramic fiber material.
  • the upper edge 16 of the component 15 facing away from the burner plate 5 is intended for attachment or pressing under a glass ceramic hotplate 17.
  • a sealing cord can be provided between the upper edge 16 of the component 15 and the glass ceramic hotplate 17.
  • An integrated component 18 is provided for electrical ignition, ignition protection, temperature limitation and as residual heat contact, which combines these functions.
  • the component 18 consists of a commercially available protective temperature limiter, on which an ignition head is attached. The flame is monitored by means of an ionization electrode 18 'of the component 18, which is formed by the core of the safety temperature limiter.
  • the component 18 is screwed to the base plate 4 in an electrically insulated manner by means of a holding plate 19.
  • the ionization signal is taken from the holding plate 12.
  • the component 18 is inserted through an opening 20 in the component 15 into the space between the burner plate 5 and the glass ceramic hotplate 17. Several openings 20 are for different positions of the component 18 is provided. The openings 20 that are not required are closed by means of plugs (see FIG. 1), or are not drilled at all.
  • the collar 3 is integrally formed on the base plate 4 itself. It is therefore not necessary to have a separate component for the design of the adjustment collar 3.
  • An edge 21 in which the mixing chamber 8 with its distribution plate 12 can be inserted can be angled on the adaptation collar 3.
  • the adaptation collar 3 passes from the circumference of the gas-air mixture outlet 11 or the distribution plate 12 into the circumference of the burner plate 5, the gas-air mixture flow leaving the distribution plate 12 expanding to the burner plate 5 largely uniformly (cf. arrows G) and thus the burner plate 5 is largely uniformly applied over its essential surface, so that a largely uniform carpet of flame is formed on its side facing away from the distribution plate 12.
  • the adapter collar 3 is connected to the mixing chamber 8 in a gas-tight manner, for example by brazing, welding or gluing.
  • a sealing material can also be provided on the joint between the adaptation collar 3 and the mixing chamber 8, wherein the adaptation collar 3 can be connected to the mixing chamber 8 by screws.
  • the base plate 4 is the supporting component of the gas radiation burner 1. The base burner 2 hangs on it.
  • the adaptation collar 3 can be formed in one piece with the mixing chamber 8 or the distribution plate 12. The conically widening adjustment collar 3 is then cut off depending on the diameter of the respective burner plate 5. With different burner plate diameters, there are different distances a due to the geometry.
  • the burner plate 5 of the gas radiation burner 1 ' has a smallest diameter Dl of approximately 145 mm, corresponding to the cooking zone of the glass ceramic hotplate 17 assigned to it and not flared as in Figure 4.
  • the burner plate 5 has the diameter D2, for example 180 mm, corresponding to the assigned cooking zone of the glass ceramic hotplate 17.
  • the burner plate 5 of the gas radiant burner l 1, 1 ' accordingly has its associated cooking zone of the glass ceramic cooking plate 17 the diameter D3, where Dl ⁇ D2 ⁇ D3.
  • the diameter D3 is approximately 210 mm.
  • the base burner 2 of the gas radiation burner 1 ′′ and 11 ′ are the same size as the base burner 2 of the gas radiation burner 1 ′.
  • the diameters of their distribution plates 12 are therefore the same.
  • the respective adjustment collar serves 3.
  • the adjustment collar 3 of the gas radiant burner l to adapt to the diameters D2 and D3 1 ' accordingly has a smaller angle of taper than the adjustment collar 3 of the gas radiant burner 1''' when the same spacing a in the radiant gas burners 1 '' and l 1 ' 1 is desired. If the same distance a is not important, the adjustment collar 3 can be used for both
  • Gas radiation burners 1 ′′ and 11 ′ have the same conical angle, the distance a then changing accordingly.
  • the gas radiation burner l 1 ,! 11 ,! 111 are arranged at different points under the glass ceramic hotplate 17 and the exhaust gas guide channels 6 are to be designed in a similar manner, extension elements 23, 24 are provided with which the exhaust gases from the exhaust gas guide channels 6 can be conducted into the exhaust gas guide shaft 22.

Abstract

Les brûleurs à rayonnement gazeux qui s'utilisent notamment dans des plaques de cuisson en vitrocéramique présentent dans chaque cas un tube mélangeur et une chambre de mélange, ainsi qu'une plaque de brûleur maintenue sur une tôle de base, les plaques de brûleur étant de dimensions différentes. Afin d'éviter d'avoir une dimension adaptée de la chambre de mélange pour chaque dimension de brûleurs à rayonnement gazeux, les brûleurs à rayonnement gazeux (1) présentent des brûleurs de base (2) de conception identique. Les plaques de brûleur (5) de différentes dimensions sont soutenues par une tôle de base (4) à une distance a. Un rebord d'adaptation (3) s'étend entre la chambre de mélange (8) et chaque tôle de base (4).
