Definitions

  • the present invention relates to an ignition and monitoring device according to the preamble of the main claim.
  • thermoelectric ignition fuses both for fuel-heated heat sources working with and without mains voltage, in particular gas-heated water heaters (see, for example, FR-A-2 125 856 and DE-A-1 551 966). It is assumed that regardless of the support with mains voltage, the pilot burner's pilot flame burns regularly during the main burner's pauses.
  • the present invention is therefore based on the object of providing an ignition and monitoring device with the support of a supply voltage source which can also be used manually independently of the operation of the supply voltage source.
  • the technical progress that can be achieved in this way is that the user can use the heat source even if the mains voltage fails, while there is no impairment of usability when the supply voltage source is present.
  • a fuel-heated heat source not shown, whether it is a gas or oil-fired boiler, circulating water heater or continuous water heater, has a main burner 1, which is controlled by a main fuel valve 2, the actuating rod 3 of which is actuated by a heat demand switch 4 controlled by a consumer of the heat source.
  • the heat demand switch can either be a room thermostat, i.e. the actuator of a room temperature sensor, or a water switch which is acted upon by the water flowing through in a continuous-flow heater after the start of the tap or in a circulating water heater after a pump has responded.
  • An extension of the rod 3 leads to a changeover switch 5.
  • the main fuel valve 2 is located in the course of a fuel line 6, which is controlled by an ignition safety valve 8 in the area of the input 7 of the heat source and from which a pilot fuel line 9 branches off, which splits into a line branch 10 and 11, which are jointly connected to a pilot burner 12 .
  • a solenoid valve 13 is provided which can be actuated by a solenoid coil 14, which can be supplied with voltage via a line 15. The solenoid valve 13 is closed when the excitation coil 14 is de-energized.
  • a manual valve 17 which can be actuated by a handle 16 is provided, with the valve or the handle being assigned a normally closed contact 18 which is provided in the course of a line 19 which leads to the pole R of a mains supply voltage source with the other pole Mp.
  • thermocouple 20 which is connected via lines 21 and 22 to an electromagnet 23 of the thermoelectric ignition fuse.
  • thermoelectric ignition fuse also has an armature 24 which is connected to an actuating rod 25 to which the valve body of the valve 8 is also articulated.
  • a handle 26 or a normally closed contact 27 is connected to the rod 25 and is provided in the course of the line 19, in series with the normally closed contact 18.
  • the ignition safety valve 8 is, as usual, under tension so that the valve 8 is closed in the idle state.
  • the ignition valve 17 can be opened as well as closed in the idle state.
  • the line 19 continues behind the contact 27 and leads to the changeover switch 5.
  • the changeover switch has two contacts, one of which is connected to a line 28 in the idle state and to another line 29 in the working state.
  • An excitation coil 31 of a relay 32 provided with two changeover contacts and a further excitation coil 33 of a relay 34 are connected to the line 28 via a line 30, the latter relay having a normally open contact 35, the release time of which is delayed.
  • Another line 36 leads to the make contact of the one switch of the relay 32.
  • the base of the make contact 35 is connected via a line 37 to the base of the changeover contact 38 of the relay 32.
  • the line 37 is connected via the normally open contact 38 to a line 39 which leads to the primary side of an ignition transformer 40.
  • the secondary side of the ignition transformer leads via line 41 to an ignition electrode 42, which is assigned to the pilot burner 12.
  • a line 43 branches off from the line 39 and is connected to the normally closed contact 44 of the relay 32, in the idle state of the relay 32 the line 43 is connected to a line 45 which leads to a thermosimulation voltage element 46. From the thermal simulation element 46 lead two lines 47 and 48 to the ignition fuse, line 47 is connected to line 22, line 48 to line 21.
  • the other pole Mp of the supply voltage source is grounded, accordingly the excitation coil 14 in the ignition gas path, the thermal voltage simulation element 46, the excitation coil 31 and 33 and the ignition transformer are also grounded on one side.
  • the circuit just described has the following function: starting from the idle state shown in the circuit, that is to say when there is no current, the normally closed contact 18 is closed, but the normally open contact 27 of the ignition fuse is open. The supply voltage source is thus disconnected from the changeover switch 5. All relays are de-energized. The main fuel valve 2 and both pilot gas valves are closed. If the handle 16 is actuated in this state, the ignition gas valve 17 opens, but its opening remains ineffective because of the closed state of the ignition safety valve 8.
  • the relay coil 31 Since the line 28 is now dead, the relay coil 31 is switched off, so that the changeover contact 44 and the working con. Clock 38 go into the rest position without delay, but the normally open contact 35 is still subject to the dropout delay of the relay 34.
  • the supply voltage is connected to the ignition transformer 40 via the lines 29, 37 and 39, so that the fuel escaping from the pilot burner 12 via the Ignition electrode 42 is ignited.
  • the thermocouple 20 is heated and takes over the supply of the electromagnet 23. Its supply ends after the end of the drop-out delay of the relay 34, since with the switching back of the contact 35 the line 45 is no longer under supply voltage and thus the thermocurrent simulation element 46 is no longer supplied with voltage. If the ignition of the pilot burner 12 does not succeed, the ignition safety valve 8 closes when the delay in decay of the relay 34 expires.
  • thermocouple 20 is interrupted after the cooling time has elapsed, and the thermocouple is simulated again via contacts 35 and 44 is taken over.
  • the variant of the invention according to the figure two is that the branching of the pilot fuel line 9 is omitted, rather the handle 16 works directly on the valve body of the solenoid valve 13. Operating the handle 16 causes the pilot gas solenoid valve 13 to lock in the open position, so that the same function as in the embodiment according to FIG. 1 results. There is an advantage in terms of cost, since the branching in the pilot fuel path and the manually operated valve 17 are saved.
