Definitions

  • the invention relates to a device for securing a Gas burner against unburned gas one arranged in the gas supply line, by hand actuable valve and an additional one in the line arranged solenoid valve that when extinguished Flame closes, and one at the gas burning point arranged spark plug through which the gas is ignited and which indicates whether gas is escaping unburned.
  • thermocouple delivers burning gas flame a thermal current for magnet use and keeps the spring-loaded gas valve open as long as how the gas flame heats the thermocouple probe tip. If the gas flame on the burner goes out, that closes Gas valve of the solenoid insert the gas flow to the burner.
  • thermocouple which is a solenoid valve as long as the flame burns.
  • the Time from extinguishing the flame to closing the solenoid valve is relatively long.
  • JP 5615816 known per se, the gas supply quantity electronically Taxes. The flame is not monitored here intended.
  • the object of the invention is to protect against unburned escaping gas to a gas hob improve that with a no longer ignitable burner the unburned gas flow automatically and is interrupted as quickly as possible and at the same time Release of the gas flow via the gas valve Indentation time at the valve is drastically restricted.
  • This object is achieved in that the solenoid valve and the spark plug with one electronic control device are connected, the with unburned gas, the spark plug to Ignition brings and if the ignition is unsuccessful within one predetermined time or number of Ignition pulses the solenoid valve closes.
  • the liability of the spring-loaded solenoid valve by a single Push in the switching axis of the manually operable Valve can be generated. It is also an advantage if by the switching axis of the manually operable valve Switch, in particular a microswitch, can be actuated, which switches the control device on and off.
  • the device for securing a gas burning point, especially a gas hob against unburned outflowing gas has one in a gas valve arranged electromagnet 5 (magnet insert), its necessary holding current to open the gas valve 8 during the gas combustion on the burner 4 by a electronic control device 2, in particular a (externally stored) module box on the electromagnet is transmitted with one at the same time in the Device 2 existing electronically controlled Zündund Flame monitoring module, which has a Microswitch 12 a voltage on the spark plug 3 am Burner releases. With a flashover from the The spark plug to the burner is the gas flowing out on Burner ignited, at the same time the gas flame on Burner monitored by the spark plug.
  • Control device 2 By rotating the tap axis 7 from the The electronic position is closed Control device 2, in particular module box 2, activates and supplies current for the electromagnet (Magnet insert 5). The gas path is still so far closed, although the cock plug 8 clears the gas path. If the tap axis 7 is now pressed in once, it will the magnet insert by electricity from the module box kept open and the gas flows to burner 4. This pushing gives the module box 2 the command voltage to give the spark plug 3. When a spark strikes the burner becomes between the burner and the spark plug ignited.
  • the module box 2 interrupts the power supply to Magnet insert 5 and the gas valve is closed.
