Definitions
- the invention relates to a method for igniting a gas stream and a circuit arrangement for carrying out this method, as they can be used in particular for gas control valves for a gas heating furnace.
- Possibilities for igniting a gas stream are available in a variety of designs.
- the ignition device comprises a solenoid which actuates a gas valve, an igniter for electrically igniting the gas flow and a remote control, which is connected via a low-voltage line to the solenoid and the ignition on.
- the remote control includes a power supply and a timer for the timely provision of low voltage.
- a valve device for controlling the ignition of a gas burner is known.
- An actuating spindle is moved by hand to the ignition position, the ignition safety valve is opened.
- the actuating spindle need only be kept in this position for a short time, since during the movement of the actuating spindle, a micro switch is turned on. This causes a power supply to provide a voltage to hold the magnetic insert. Ignition is via a piezoelectric spark ignition.
- the power supply is switched off when the thermo-current supplied by a thermocouple is sufficient to hold the pilot-operated safety valve in the open position.
- thermoelectric fuse for gas burners of heating systems described.
- This multi-function valve uses the existing mains power supply of a room for its operation.
- a solenoid valve is energized via a pushbutton, whereby the ignition safety valve is opened.
- the ignition of the gas flow A thermocouple located in the area of the ignited gas flame is heated and brings about the resulting thermo-current a magnetic insert in the excited state.
- the magnet holds an anchor and thus also connected to the armature ignition safety valve in the open position. Now the push button can be released and the solenoid valve de-energized.
- the invention is based on the problem to develop a method for fully automatic ignition of a gas stream and a circuit arrangement for carrying out this method, which have such a low power consumption that an integrable voltage source can be used while ensuring a sufficient life. Furthermore, the structure should be as simple and inexpensive as possible.
- the problem is solved in terms of the method by activating a transverter which generates a higher voltage from a DC voltage provided by a voltage source with which a storage capacitor and a starting capacitor serving to provide the ignition voltage are charged.
- a per se known Zünd Anlagensmagnet is activated with a holding current provided by the voltage source, at the same time an existing between the Zünd Anlagensmagneten and one influenced by the gas flame thermocouple circuit is interrupted via a relay.
- the storage capacitor is then discharged suddenly, with a surge is generated, which serves for short-term excitation of an electromagnet to open a per se known Zündtechnischsventil while applying the armature of the Zündtechnischsmagneten.
- the armature Due to the activated by the holding current Zünd Anlagensmagneten the armature is held after its successful installation in this position and one with the ignition capacitor via an ignition transformer connected ignition electrode in a known manner generates a spark for igniting the outflowing gas. Subsequently, further ignition processes are initiated by the ignition capacitor recharged and after charging a renewed spark is generated. After a predetermined time, the ignition is stopped. The current flowing from the voltage source to the Zünd Anlagensmagneten holding current is interrupted and closed between the Zündtechnischsmagneten and the thermocouple existing circuit via the relay again.
- thermoelectric voltage when the presence of a thermoelectric voltage is measured, wherein in the absence of thermoelectric voltage further ignition processes, as described above, are initiated. If there is a detectable thermoelectric voltage, however, the ignition is terminated. Once the from the measured thermoelectric voltage electronically calculated thermo-current is sufficient to hold the armature on the Zünd Anlagensmagneten, the current flowing from the voltage source to the Zünd Anlagensmagneten holding current is interrupted and closes the existing between the Zündtechnischsmagneten and the thermocouple circuit via the relay again.
- the storage capacitor and the ignition capacitor are relatively easily charged via a respective associated transverter to different voltages.
- the method if from the voltage source provided by the DC voltage higher AC voltage is generated by a power oscillator instead of the transverter is used and the storage capacitor until the initiation of the ignition to a power oscillator downstream first stage of a multiple cascade is switched, after which the storage capacitor and the electrically connected to the second stage of the multiple cascade ignition capacitor are charged by the higher AC voltage through the cascade to predetermined higher DC voltages. After reaching the predetermined higher DC voltages of the power oscillator is turned off and turned on when initiating further ignitions again.
- the holding current provided by the voltage source for holding the armature simultaneously via the Zündêtsmagneten and the relay flow, wherein at the time of closing the between Zündtechnischsmagnet and thermocouple existing circuit briefly an additional current is generated to reliably prevent the armature during Switching the relay due to the momentary power interruption at intermediate position the switching contacts of the relay drops.
- the voltage of the holding current provided by the voltage source it is also conceivable for the voltage of the holding current provided by the voltage source to be provided to the ignition fuse magnet to be converted into the millivolt range via an additional transverter.
- thermoelectric voltage is measured by means of an analogue amplifier
- a method step which interrupts the excitation of the Zünd Anlagensmagneten via the voltage source in addition by one or more independent series-connected and timed safety shutdown after a defined period of time.
- the period between the first ignition and the following ignition is kept as short as possible, it is favorable for energy saving reasons, if the storage capacitor is switched off from the cascade before further cyclic charging of the ignition capacitor.
- a gas control valve for carrying out the method for igniting a gas stream is used in a gas control valve.
- This gas control valve is a switching and control device, which is preferably intended for installation in a gas-fired stove or the like. It enables the operation and monitoring of a burner by controlling the amount of gas flowing to the burner.
- the gas control valve has a pilot burner 1 and an ignition valve 2. The structure and function of the pilot burner 1 and the Zündschsventils 2 are familiar to the expert and are therefore not explained here.
- microcomputer module which is in this embodiment, together with a voltage source 10 in a separate location-independent housing also not shown the receiver part of a remote control.
- voltage source 10 serves as voltage source 10, as shown in the drawing, commercially available batteries, in this case the size R6.
- a power oscillator 11 described in more detail below which can be controlled by the microcomputer module via a port J, is connected to the voltage source 10. It is followed by a cascade 12/13 which serves to control and supply a downstream storage capacitor C1 and to control and supply a downstream ignition capacitor C2. Since the voltage required to charge the storage capacitor C1 is significantly less than the voltage required to charge the ignition capacitor C2, the cascade circuit 12/13 is implemented as a multiple cascade connection.
- the first stage of the cascade 12 is used to control and supply the downstream storage capacitor C1.
- an electromagnet 5 which, as shown schematically in the illustration, for actuating a known Zünd Anlagensventils 2 is used. Due to the only short-term load in this case a thermally undersized so-called pulse magnet 5 is sufficient.
- the second stage of the cascade 13 serves to control and supply the downstream ignition capacitor C2, which is part of a known per se, and therefore not explained in more detail here ignition device. Via a port C, the ignition capacitor C2 can be controlled by the microcomputer module for ignition. Furthermore, the second stage of the cascade 13 is connected to a voltage monitoring element 14. At the same time, the element 14 serves to limit the occurring maximum voltage in order to prevent the destruction of components. In this case, an additional voltage monitoring for the storage capacitor C1 can be dispensed with since, after the ignition capacitor C2 has been charged, it can also be assumed that the storage capacitor C1 has been charged up. For feedback to the microcomputer module is the Port D.
- the power oscillator 11 consists of a CMOS circuit 15, which is known per se to a person skilled in the art, with at least four gates. These gates can be NOR gates, NAND gates, simple inverters or similar. Subordinate to them is a complementary field effect power stage 16, which is followed by an LC series resonant circuit consisting of coil L1 and HF capacitor C3. For feedback and phase adjustment serves as a so-called phase shifter 19, an RC element.
- an ignition fuse 6 associated Zünd Anlagensmagnet 6 is connected to a thermocouple 4.
- the opener of a monostable relay 17 is additionally arranged, whereas in the energized state this circuit is open and the ignition safety magnet 6 is energized by the voltage source 10 formed by the batteries.
- a switching element in this case a transistor T1, which can be controlled by the microcomputer module via port G, is connected on the one hand to the voltage source 10 and on the other hand to the relay 17.
- a resistor R1 is additionally arranged, since the holding current required for the Zündtechnischsmagneten 6 is higher than the current flowing through the relay 17 current.
- there are two series-connected timed safety shutdowns 18 in this circuit which are connected via the ports H and M in terms of control with the microcomputer module.
- a transistor T2 and a transistor T3 are connected to this circuit. While the transistor T2, which is preceded by a resistor R3, connected to the negative terminal of the voltage source 10 and can be controlled via the port F from the microcomputer module, the transistor T3 is connected to the positive terminal of the voltage source 10 and can via the port E from the microcomputer module be controlled.
- an analog amplifier 20 is connected in parallel with the thermocouple 4.
- This analog amplifier 20 has the task of measuring and amplifying a DC voltage of the thermocouple 4 which occurs in the millivolt range and to convert it into a variable that can be processed for the microcomputer module. Since the DC amplifiers otherwise customary for such cases require, on the one hand, an additional auxiliary voltage lying above the operating voltage and, on the other hand, drift deviations, for example due to temperature influences, the analog amplifier 20 is designed as an AC amplifier.
- the reference potential is formed by the positive voltage in order to eliminate fluctuations in the on-board voltage.
- the repeater V2 the reference potential is formed by mass.
- Both amplifiers V1 / V2 and a trigger TR are put into operation via the port K of the microcomputer module, since they are put out of operation as a power saving measure when not in use.
- the trigger TR located behind the postamplifier V2 is in turn connected to the microcomputer module via port 1.
- the command for igniting is given to the microcomputer module via the remote control.
- the activated via port K analog amplifier 20 is checked whether the thermocouple 4 is applied a thermoelectric voltage and given the appropriate information via port I to the microcomputer module. While in the presence of a thermoelectric voltage, which is synonymous with a burning pilot flame, the ignition process is stopped, the voltage divider of the analog amplifier 20 is controlled by the microcomputer module via port L in the absence of a thermal voltage. By a single circuit of the voltage divider, the present at the thermocouple 4 DC voltage is converted into an AC voltage pulse. Via the coupling capacitor C4, the pulse reaches the preamplifier V1.
- the signal coming from the preamplifier V1 is coupled via the coupling capacitor C5 to the post-amplifier V2 and amplified again.
- This analogue signal coming from the postamplifier V2 is triggered by the trigger TR at fixed trigger points, as in the Fig. 3 associated diagram, digitized.
- the curve of the voltage U over the time t is plotted.
- the trigger TR is in a predetermined voltage level SE at the Initiation of the pulse signal IS at the time TL, a first trigger point TR1 and the fall of the voltage of the pulse signal IS set a second trigger point TR2, which is assigned a time TE.
- the time interval between the two times TL and TE is a measurement signal MS.
- the measurement signal MS thus obtained from the existing thermal voltage passes through the port I to the microcomputer module for evaluation.
- the length of the measuring signal MS is directly proportional to the thermoelectric voltage present on the thermocouple 4.
- the resonant circuit By activating the power oscillator 11, the resonant circuit begins to oscillate via the feedback member, i. the resonant circuit is the self-oscillating and frequency-determining power oscillator 11.
- the resonant circuit is the self-oscillating and frequency-determining power oscillator 11.
- the storage capacitor C1 and the ignition capacitor C2 are charged with the aid of the two cascade stages 12/13 of the multiple cascade until the voltage monitoring and limiting of the maximum voltage occurring element 14 responds and sends a signal to the microcomputer module via the port D, which then via the port J the power oscillator 11 turns off.
- the time-controlled safety shutdown 18 are activated via the port M and supplied via the port T G driven transistor T1 of the Zündtechnischsmagnet 6 with a coming from the voltage source 10 holding current by the relay 17 is energized and so the circuit between the Zündtechnischsmagneten 6 and the thermocouple 4 is opened.
- the port B the storage capacitor C1 is discharged suddenly.
- the storage capacitor C1 is disconnected from the cascade stage 12 via port A.
- the pulse magnet 5 is briefly energized by this surge and a plunger 7 is moved against the force of a closing spring 8 until the armature 3 comes to rest on the Zündtechnischsmagneten 6. Due to the flowing holding current of the armature 3 is held in this position and thus the Zündtechnischsventil 2 in the open position.
- the gas can flow through the gas control valve to the pilot burner 1.
- the energization of the Zündtechnischsmagneten 6 via the voltage source 10 is additionally interrupted by one or more independent series-connected and timed safety shutdown 18 after a defined period of time and the Zündtechnischsventil 2 does not remain in the open position, but is closed by the closing spring 8 again.
- Via port C is activated by the microcomputer module, the ignition device, the ignition capacitor C2 discharges and it comes to the ignition electrode 9 to skip the spark, causing the outflowing gas is ignited.
- the analog amplifier 20 is activated via the ports K and L and it is checked whether the thermocouple 4 due to the incipient heating by the burning pilot flame already a detectable voltage, i. at least approx. 1 mV.
- thermocouple 4 In the presence of the minimum voltage, of course, no further ignition operations are initiated, but the existing no-load voltage of the thermocouple 4 is further checked until the size of the electronically calculated therefrom current is sufficient as holding current for the Zünd Anlagensmagneten 6. Thereafter, the analog amplifier 20 is deactivated via port K and interrupted via port G of the current flowing from the voltage source 10 to the Zünd Anlagensmagneten 6 current. The relay 17 is de-energized and the switching contacts of the relay 17 close the circuit between the thermocouple 4 and Zündtechnischsmagneten 6. The armature 3 is now held by the thermo-current.
- the transistor T2 is activated for a short time at the time of switching over the port F and an additional one is also present for a short time via the resistor R3 Electricity generated, the above Fall of the anchor prevented with certainty.
- the command for switching off is given to the microcomputer module via the remote control.
- the switching contacts thus briefly lift off.
- the holding current flowing between the thermocouple 4 and Zünd Anlagenungsmagneten 6 is interrupted.
- the armature 3 is no longer held by the Zündtechnischsmagneten 6 and under the action of the closing spring 8 closes the Zündtechnischsventil 2.
- the gas supply to the pilot burner 1 and of course to the main burner, not shown, is interrupted and the gas flame goes out.
