  • the weight of the hob can be further reduced by the common component 9 for the hotplate burner 1 and the warming zone 7 (FIG. 1) being made from foamed aluminum silicate material with a binder. If this material is open-pore, an additional seal in the gas mixing chamber area of the component 9 is required. As shown in FIG. 7, this seal can be achieved by inserting a gas mixing chamber 3 into the component 9 as a tin pot 3a, in the seat 17a of which the nozzle plate 6 is glued.

  • the burner 24 is ignited by the exhaust duct 5 via a pilot burner in the cooktop center, which together is provided there for all the burners of the hob (see also FIG. 1). Only one ignition tube 10b of this pilot burner is shown in FIG. If the hotplate burner is ignited and monitored individually, 24 ignition electrodes 101 and monitoring thermocouples 111 are attached to the respective burner in a known manner instead of the common pilot burner. These parts are indicated by dashed lines in FIG. 8.
  • thermocouple The operational safety of the cooktops with gas radiant burners is significantly improved if a gas safety switch is arranged in front of the solenoid valves, which are required for controlling the heat requirement of the hotplate, which is secured in a known manner with a thermocouple. It is advantageous that the monitoring circuit of the thermocouple and gas safety switch works without auxiliary energy and completely independently of the control circuit with the solenoid valves and offers additional safety if the solenoid valve fails. As is shown schematically in FIG. 1, a common pilot burner 10 with monitoring thermocouple 11 is expediently and inexpensively provided, which actuates a common gas safety switch for all burning points 1, which is connected to the main gas line of the hob.
  • FIG. 9 shows a suitable pilot burner, for example for the ignition and monitoring of three burning points.

  • the gas-air mixture flows into the burner, it exits at the fine bores 10h and 10e as well as at the pilot flame nozzle 10i and the end nozzles 10f of the ignition tubes.
  • a flame seam is formed both around the burner head 10a and along the ignition tube 10b, which ignites the gas-air mixture at the nozzles 10f. This allows pilot lights to burn into the combustion chambers of the hotplate burners, or a gas / air mixture flowing out from there is ignited.
  • FIG. 10 A modification of the pilot burner according to FIG. 9 is shown in FIG. 10.
  • the pilot tubes 10b (FIG. 9) are omitted and the pilot lights burn directly on the pilot burner head 10a.

  • openings are provided such that the pilot burner 29, which forms a unit with the ignition electrode 28, projects onto the edge of the combustion chamber 2, so that the pilot flame can heat the monitoring thermocouple 11. It is advantageous in this arrangement that the pilot flame of the burner 29 burns just above the burner nozzle plate 6, as a result of which the gas-air mixture of the main burner is ignited immediately after the hob switch has been actuated.
  • FIG. 12 shows a hotplate burner 1 with the combustion chamber 2 and the exhaust gas duct 5, both of which are molded into the component 9 made of refractory material, with the gas mixing chamber 3 and gas inlet 54.

  • the nozzle plate 6 and the housing of the gas mixing chamber 3 have an opening 38a in the vicinity of the exhaust gas duct for the pilot flame 41 of the pilot burner 110 arranged under the opening 38a. So that no gas-air mixture from the hotplate burner 1 reaches the combustion chamber 2 from its mixing chamber 3, a ceramic tube 38 is glued gas-tight in the opening 38a to the nozzle plate 6 and the housing of the gas mixing chamber 3.
  • the pilot flame 41 now burns perpendicularly to the exhaust gas flow from the hotplate burner 1 and is no longer adversely affected by it - even during ignition and extinguishing processes. In particular, the extinguishing of the pilot flame 41 by pressure surges in the combustion chamber 2 is avoided with this pilot burner arrangement.
  • an incandescent body 43 is installed below the cooking surface 14 above the opening 38a, which prevents the tip of the pilot flame 41 from locally overheating the cooking surface 14.

  • a switch 49a is connected to the control circuit of the thermocouples 45 and is coupled to the corresponding energy regulator 49. With the aid of an electrically heated bimetal switch, the energy regulators 49 generate a timing of the supply current of the control valves 50 and thus control the hotplate temperature in a known manner via the selectable operating time of the hotplate burner 1. The required direct current for the control valves 50 is generated with the rectifiers 52.
  • the changeover switch 47a switches off the high-voltage device 48 and thus the ignition sparks.
  • the power supply of the energy regulators 49 is switched on again with this switch and the control valve 50 of the previously switched on hotplate burner 1 is opened.
  • the associated gas safety switch 46 remains open because the thermocouple circuit is closed with the switch 49a and the valve plate of the gas safety switch is thus held in the "open" position by its current coil.
  • the pilot burner 110 of the hotplate which is not switched on is released when the manual button 47 is released because its thermocouple circuit is interrupted by the switch 49a in the energy regulator 49 of this hotplate burner.
  • the pilot burner 110 of the switched-on hotplate remains in operation regardless of the operation of the associated energy controller 49 and rod temperature limit switch until the hotplate on the energy controller 49 is switched off. If this is the case, then both the control valve 50 and the current coil of the gas safety switch 46 are de-energized and both valves close.
  • the gas safety switch closes after a safety period and blocks the gas supply to both the pilot burner 110 and the hotplate burner 1.
  • the hotplate can then only be operated in the manner described above by actuating the manual button 47 can be switched on again. If one of the two burner burners 1 is already switched on and the second burner burner is to be switched on, the described ignition process is repeated accordingly. In this case, the hotplate burner 1 that is already switched on goes out for the duration of the ignition process, while its pilot burner remains switched on. When the hand button 47 is released, the second pilot burner now remains switched on and both hotplate burners ignite via the corresponding pilot lights.
