Definitions

  • the invention relates to a device for protecting the edges of openings in moldings made of glass ceramic, glass or ceramic, in particular from Openings for the passage of atmospheric gas burners in cooking hobs, against mechanical damage and to avoid contamination and Damage to arrangements lying under the molded body due to the openings in the molded body penetrating liquids, one over the Edge of the respective opening on the molded body overlapping metallic Cap is attached and between the molded body and the metallic A sealing and heat-resistant material is introduced.
  • the gas burners are fixed in the support frame or housing.
  • A, in particular, toughened glass plate covering the surrounding surface of the gas burner is provided with a much larger opening than would actually be required for the respective gas burner.
  • the wide annular gap thus formed between the gas burner and the lead-through edge is covered with a simple annular collar made of sheet metal. This ensures mechanical separation of the gas burner from the glass plate, but this method of mounting the gas burner inside the glass plate has a disadvantageous effect in practical use, particularly with regard to the cleaning behavior.
  • overcooked food can penetrate into the joint between the tempered glass plate and the sheet metal collar. Cleaning these devices is difficult and often even requires at least partial disassembly.
  • DE 41 33 409 C2 shows a burner arrangement, for example for cooking hobs, in which at least one gas burner is mounted in a support frame and the surrounding surface of the gas burner by means of a shaped body made of glass, Glass ceramic or ceramic, is covered, with each gas burner a passage in the molded body extends over the top thereof and a permanently elastic connection between the molded body and each gas burner and sealing device with a solid and liquid-tight the edge area of the passage and at least one formed by the gas burner Connection surface engaging connecting and sealing element attached is, wherein the gas burner is carried by the shaped body and Safety and holding devices between the gas burner and the support frame are attached, in the event of breakage of the molded body and thus elimination its load bearing capacity with limited mobility Restraint and torsion protection for each of the gas burners are effective.
  • GB-A-2 149 089 describes a device for protecting the edges of Openings in shaped bodies made of glass ceramic, glass or ceramic, in particular of openings for the passage of atmospheric gas burners in cooking hobs, against mechanical damage and to avoid contamination and damage to arrangements under the molded body liquids penetrating through the openings in the molded body, whereby one over the edge of the respective opening onto the molded body metallic cap as a comprehensive collar part of the burner itself is appropriate.
  • the object of the invention is therefore the above in a burner arrangement described type a fully effective for practical use, sealing and / or heat-insulating protective device between the gas burner and to provide the molded body consisting of glass ceramic, glass or ceramic, which is also easy to clean and breaks due to tension to exclude.
  • the assembly of the protective device should be simple, without gluing and with little time, material and costs be feasible.
  • the invention has for its object atmospheric gas burners sure to pass through the molded body in a suitable manner and position and provide edge protection for the edge of the hole.
  • the metallic cap has a shaft that has a smaller diameter than the opening in the molded body, and an associated, from bend the shaft axis by at least 90 ° and be flush with the molded body final collar at one end of the shaft, the other end of the shaft at least three, especially eight or more bendable Forms tabs that extend towards the level of the molded body are bendable that the throw formed by means of of its tabs which can be bent at least 90 ° out of the shaft axis and which the overlap one side of the molded body and the other by means of the collar, which lies flush on the other side of the molded body, clamping is stable on the molded body.
  • the metallic cap in addition to the bending tabs which overlap an edge region of the opening in the molded body on one side, has further tabs which protrude into the interior of the opening and thus serve as abutments for a surface formed by the gas burner. Or the tabs projecting into the interior of the opening even form two parallel planes, between which a surface formed by the gas burner is held. This considerably simplifies the positioning and centering of the burner.
  • the metallic cap can be made in one piece and the tabs as bending tabs be trained. Sometimes it is also advantageous to use the metallic one To form the cover in several parts and the parts forming the cover by press fitting, soldering, gluing, screwing or by one To connect bayonet lock, with this variant preferably in addition also tabs are designed as bending tabs.
  • the metallic cap as a collar ring formed with a cylindrical shaft
  • the collar ring in preferred embodiment also open, as a prestressed spring element can be formed that itself at the edge of the opening in the molded body presses.
  • All embodiments of the protective device according to the invention have in common that expediently between the molded body and the metallic Throw a sealing and / or insulating material, in particular a graphite-containing temperature-resistant material and / or a ceramic fiber material is introduced.
  • the seal On the top side, the seal has the task of being liquid-tight Barrier between cap and glass ceramic, glass or ceramic z. B. against Overcooked goods and / or cleaning agents form on the underside the seal protects the molded body from mechanical scratches and damage through the metal.
  • the collar of the metallic cap in particular Openings for air supply in the vicinity of the shaft Have supply to the gas burner, the openings for the air supply positioned or covered to protect against moisture.
  • FIGS. 1a and 1b show a one-piece, metallic coupling ring (1) with one overlapping on the top of the glass ceramic plate (3) Collar (2) and with a shaft (4) of a smaller diameter than the hole (5) has.
  • Tabs (6) are formed at the end of the shaft (4) (at least 3 pieces, preferably 8 pieces), which simply by 90 ° bent outwards over the glass ceramic plate (3) and the ring (1) so clamp on the edge of the opening (5) of the glass ceramic plate (7).
  • FIG. 2c shows a particularly simple preform of a metallic one Take the throw over, one on the top of the glass ceramic plate (3) overlapping collar (2), a shaft (4) with bending tabs (6) and also additionally in the interior of the opening (5) in the molded body (3) reaching part (2 ').
  • FIG 3 a one-piece collar ring (1) is shown, one of the Overlaps (2) / (2 ') on the top of the molded body (3) also simultaneously is led into the interior of the bore (5) and there as a replacement for the burner (8).
  • the tabs (6) / (6 ') at the end of the Shafts (4) are mutually facing both outwards over the glass ceramic (3) and bent in the other direction over the burner (8).
  • Figure 4 shows a two-part metallic coupling ring (1).
  • Two Rings one ring for the top (1 ') and one ring for the bottom (1 "), with circumferential overlaps (2) / (6) and matched to each other Shaft diameters (4) / (4 ') are inserted into each other from below and above and protect the drilling edge (7) in this way. Adjusting the shaft diameter must be such that the ring pairing (1 ') / (1 ") is not can solve independently. This can e.g. B. by an interference fit of the two Parts done. Another option is the two rings (1 ') / (1' ') to be soldered or glued together.
  • Figures 5a, b and c show three possible variants of a two-part Embodiment of the protective device according to the invention overlapping Collar (2) / (2 ') on the top of the molded body (3) at the same time is guided into the interior of the opening (5) and there as an abutment for the burner (not shown).
