  • the construction is intended to be easy to assemble during manufacture and disassembly enable in the event of service, it being particularly important that the The device must be assembled without "overhead installation” and in the case of service without disassembly of the cooking appliance can be serviced from the worktop. This part of the task is particularly useful for economic considerations such solutions very important because of a simple assembly from above on the one hand, the production costs can be reduced considerably, and on the other others, the times for maintenance in the event of service are significantly reduced can.
  • Another object of the invention is also torches with different geometries, as they are available on the market, with glass ceramic, glass or ceramic cooking surfaces to be able to use.
  • the part of the construction which overlaps the shaped body as a collar in the form of a ring disk or frame from above and forms an abutment for the gas burner is detachably connected, in particular screwed, to the burner.
  • the connection is made via a flange-like projection which is formed on the burner, this projection having a smaller diameter than the opening in the molded body, but a larger diameter than the diameter of the inner region of the sleeve of the part of the construction which extends above.
  • the resilient is attached metallic element of the part of the construction that forms the molded body engages between the one with the flange-like projection of the burner connected cuff.
  • the resilient metallic element is attached to a crossbar which is positively connected to the frame of the hob, the crossbar being hung in tabs which are provided in the hob.
  • the burner has a Another resilient element and / or via guide bolts that are on the floor Support the hob and from below against the cuff of the part of the Construction that overlaps the molded body from above, positioned and is pressed.
  • Figure 1 is the arrangement of a gas burner 9, here in the special form a so-called pot burner in a glass or glass ceramic cooktop 1 shown.
  • the burner 9 and the sleeve 6 are a screw as a connecting element 10 screwed against each other.
  • Burner 9 and cuff 6 causes the burner 9 attached to the underside Spring 4 a force F in the opposite direction to the glass or Glass ceramic hob 1.
  • the burner 9 with the mounted sealing washer 5 to the glass or glass ceramic cooktop 1 pressed.
  • the gas burner / glass ceramic cooktop system is therefore mechanically different from that Hob 3 decoupled.
  • a blow to the glass ceramic cooktop 1 or on the gas burner 9 consequently no leverage can arise, which are caused by rigidly mounted components of the hob 3, the rest on the underside of the glass ceramic hob 1 or in very little Distance. These forces can be exceeded when the maximum Resilience of material lead to breakage.
  • FIGS. 2, 3 and 4 show the arrangement of another, further gas burner 9 shown on the glass ceramic cooktop 1.
  • Central component of this arrangement is the traverse 8, which is in tabs 2 in the frame of the cooking device 12 is mounted.
  • a bracket 11 On this cross member 8 is a bracket 11 the cuff 6 attached.
  • Traverse 8, mounting bracket 11 and sleeve 6 are releasably connected to one another via screw connections 10.
