Abstract

The invention relates to a method and a circuit for igniting a gas flow in a fully automatic manner. The aim of the invention is to maintain the necessary current consumption so low that an integratable voltage source can be used. To this end, once an electronic control unit has been activated, a thermoelectric safety pilot valve (2) is opened by an electromagnet which is temporarily excited by a rush of current, is maintained in the open position by a safety pilot magnet (6) by means of a holding current provided by a voltage source (10), and the escaping gas is ignited. Once a thermoelectric couple (4) is provided for the necessary holding current, the voltage source (10) is switched off. In the event of damage, the method is automatically interrupted.

Description

METHOD AND CIRCUIT FOR IGNITING A GAS FLOW}

The present invention relates to a gas stream ignition method and a circuit arrangement for carrying out the method, which can be used in gas heating stoves with gas conditioning components.

Equipment for gas heating stoves or the like is available in a number of constructions.

In addition, an ignition device for igniting gas is described in US Pat. No. 5,722,823 A. The ignition device has a magnetic coil for actuating the gas valve, an igniter for electrically igniting the gas stream, and a remote control connected to the magnet coil and the igniter by a low voltage line. The remote control includes a time switch for adjusting the time to provide the energy supply and the low voltage.

This design requires a lot of energy to ignite the gas stream. Thus three relay coils are provided, which means a relatively high power input. The solenoid valve is energized continuously during the ignition process, thus consuming high power. The only means of energy supply selection is therefore the main supply. Another disadvantage is that defects occurring within the switch can be a safety concern.

The valve arrangement for controlling the ignition of the gas burner is familiar from GB 2 351 341 A. When the operating spindle is moved to the ignition position by hand, the ignition lock valve opens. The working spindle needs to be fixed very briefly in this position because the microswitch is engaged when the working spindle is moved. This makes the voltage available from the power source and couples with the magnet. Ignition is generated by piezoelectric spark ignition. The power source is switched off when there is enough thermoelectric current provided by the thermocouple to keep the ignition lock valve open.

With this solution, using a power supply is a disadvantage. There is also a need for additional effort to perform piezoelectric spark ignition. Since the time between the opening of the ignition lock valve and the ignition is relatively short, there is a problem that in a special case where there is a fairly large conductive gap between the ignition lock valve and the burner hole, there can be no gas mixture that can ignite in the burner hole.

In addition, DE 93 07 895 U describes a multi-function valve with a thermoelectric lock for the gas burner of the heating device. This multifunction valve is operated using existing power sources in the room. To ignite the gas flow, the magnetic valve is energized by a push button to open the ignition lock valve. The gas stream is ignited at the same time. The thermocouple in the ignited gas flame zone is heated and causes the magnet insert to enter the energized state by thermoelectric current. The magnet holds the anchor firmly so that the ignition lock valve is connected to the anchor in the open position. The push button can now be released and the magnetic valve will be energized.

The disadvantage here is that the pressure valve must be kept long enough until the thermoelectric current can hold the ignition lock valve in the open position. It is also disadvantageous that the power consumption is relatively high in view of the fact that the magnet valve must continue to receive voltage during that time through the power source.

In addition, both GB 2 351 341 A and DE 93 07 895 U have the disadvantage that they cannot be fully automatic and require manual operation.

The method and circuit arrangement according to the invention for igniting a gas stream is described in more detail in the examples below. Each representation is as follows:

1 is a schematic diagram of a circuit arrangement;

2 is a detailed view of a power oscillator.

3 is a detailed view of an analog amplifier.

The present invention is based on the problem of developing a method for igniting a gas stream and an apparatus for performing the method to facilitate ignition by remote control. Furthermore, the required power consumption is kept low enough so that the entire power source is used. The structure should also be as simple as possible.

According to the present invention, a procedure problem is solved by operating a transverter, which generates a higher voltage from the direct current provided by the power supply, and a storage capacitor and an ignition capacitor are used to provide an ignition voltage. Filled with power. In essence, the familiar ignition lock magnet is operated by a holding current provided by the power supply, while at the same time an electrical circuit existing between the thermocouple and the ignition magnet which is affected by the gas flame is interrupted by the relay. The storage capacitor is now suddenly discharged by the circuit element, creating a sudden change in current and temporarily applying a voltage to the electromagnet, opening the inherently familiar locking valve, and at the same time anchoring the ignition locking magnet. Because of the ignition lock magnets activated by the holding current, the anchors are created in this state through the ignition electrodes connected to the ignition capacitors by the ignition transformer in a familiar manner to produce a gas which is released and outflowed. Thereafter, an additional ignition procedure is initiated to recharge the ignition capacitor and to generate new pilot light after charging has occurred. The ignition is terminated after a period of time for a predetermined period. The holding current flowing from the power supply to the ignition lock magnet is interrupted and the circuit between the ignition lock magnet and the thermocouple is closed via a relay.

This has found a solution, which heals the disadvantages of the prior art mentioned above. Temporary operation of the electronic control facilitates ignition of the gas stream. Taking into account the unique pulsed operation of the electromagnet, this will require very low power, no matter how long the control is operated. It is also possible to access the power source to generate pilot light, so there is no need to pay extra for the piezo ignition device.

Advantageous embodiments of the invention can be derived from other claims.

It has proven helpful to have a check to determine whether a gas flame burns after the electronic control has been activated to ignite the gas stream. If the information is positive, the ignition procedure is canceled; if negative, the steps of the aforementioned procedure are performed.

There is also an advantageous embodiment of the procedure if it is determined that there is a thermal electromagnetic force, while the ignition procedure is initiated if there is no thermal electromagnetic force. However, if there are signs of thermal electromagnetic force, the ignition is terminated. As soon as the measurement of the thermal electromagnetic force indicates that the electronically calculated thermoelectric current is sufficient to hold the anchor in the ignition lock magnet, the holding current flowing from the power source to the ignition lock magnet is interrupted and the electrical circuit between the ignition lock magnet and the thermocouple is again Closed via a relay.

It is also feasible to charge the storage capacitor and the ignition capacitor relatively easily via transverters, each assigned a different voltage.

Also, there is an embodiment of the preferred method if higher alternating current is generated from the direct current supplied by the power source, so that the power oscillator is used instead of the transverter and the storage capacitor is only switched to the first stage of the multiple cascade at the start of the ignition procedure, As a result, the ignition capacitor and the storage capacitor connected by electrical conduction with the second stage of the multiple cascades are charged to a predetermined higher voltage by higher alternating current through the cascade circuit. After the predetermined higher DC voltage is reached, the power oscillator is switched off and switched on again when another ignition procedure is initiated.

In order to further reduce the power requirements, this is very important when the power source is a battery, and the dimensions of the battery can be very small so that it can be located with the electronic control unit in the housing of the receiver section of the remote control. So that the holding current supplied by the power supply can simultaneously flow through the ignition lock magnet and the relay, and as the electrical circuit between the ignition lock magnet and the thermocouple closes, additional current is generated temporarily, which is a temporary current when the switching contact of the relay is involved. This prevents the anchor from falling off when the relay is rearranged due to interference. On the other hand, it is possible for the voltage of the holding current supplied from the power supply to the ignition lock magnet to be converted to the range of millivolts through an additional transverter.

It would also be advantageous if the presence of thermal transfer force was measured using an analog amplifier.

The safety of the method is enhanced by procedural steps, such as when a failure occurs, and the voltage of the ignition lock magnet from the power source is provided by one or more independent safety disconnects connected in series after a limited period of time and activated after a period of time. It also interferes with the application.

In order to keep the time between the first ignition procedure and the subsequent ignition procedure as compact as possible, it is desirable to save energy by disconnecting the storage capacitor from the cascade prior to further periodic charging of the ignition capacitor.

As far as the circuit arrangement is concerned, this problem is solved according to the invention by the features described in claim 12. Advantageous embodiments and further developments are set out in the relevant subclaims.

The circuit arrangement of the invention illustrated in FIG. 1 for carrying out a method of igniting a gas stream is used in a gas control valve. This gas regulating valve is preferably a switched regulating device which is installed in a gas heating chimney stove or the like. This helps to operate and monitor the burner, which regulates the amount of gas flowing into the burner. In addition to assemblies not critical to the present invention and thus not described in this embodiment, the gas control valve also has an ignition burner 1 and an ignition lock valve 2. The structure and function of the ignition burner 1 and the ignition lock valve 2 are familiar to the expert and thus will not be described in detail.

It is started by an undescribed microcomputer module which functions as an electronic control device, in which the electronic control device in this embodiment is located in the housing, also independently described, of the receiver part of the remote control together with the power supply 10. It is. The power supply 10 consists of a typical commercial battery, as shown in the figure, in this case a battery of size R6.

The power oscillator 11, described in more detail below, which can be started from the microcomputer module via port J, is connected to a power source 10. In this connection, this is a cascade circuit 12, 13 which serves to initiate and supply the downstream storage capacitor C1 and also to initiate and supply the downstream ignition capacitor C2. Since the voltage required to charge storage capacitor C1 is much lower than the voltage required to charge ignition capacitor C2, cascade circuits 12 and 13 are designed as multiple cascade circuits.

Here, the first step of the cascade 12 serves to initiate and supply the downstream storage capacitor C1. As schematically shown in the figure, in turn, the electromagnet 5 flows downstream and serves to actuate the ignition lock valve 2 inherently familiar. In view of the short charging, a low heat capacity, so-called pulse magnet 5, is sufficient.

The second stage of the cascade 13 serves to initiate and supply the downstream ignition capacitor C2, which is essentially part of the ignition device which is familiar and no longer described. The second stage of the cascade 13 is connected with the element 14 to monitor the voltage. At the same time element 14 serves to limit the maximum voltage that can occur to prevent the element from breaking. Since it can be assumed that the storage capacitor C1 is also charged after the ignition capacitor C2 is charged, the additional voltage monitor for the storage capacitor C1 can be omitted. Port D serves to send a check-back signal to the microcomputer module.

2 shows in detail the circuit of the power oscillator 11 being used. The power oscillator 11 consists of a CMOS electrical circuit 15 having at least four gates that are familiar to the expert. These gates may be NOT gates, NAND gates, simple negative devices, or the like. The supplemental field effect power stage 16 is downstream from this gate, to which the LS series oscillator circuit consisting of coil L1 and HF capacitor C3 is connected. The RC link acts as a so-called phase shifter for feedback and phase correction.

Further, as shown in FIG. 1, the ignition lock magnet 6 constituting a part of the ignition lock valve 2 is connected to the thermocouple 4. The normally closed contact of the monostable relay 17 is also located in this circuit, while the circuit is open with voltage applied and the ignition lock magnet 6 from the power supply 10 supplied by the battery. Accepts the current In addition, a circuit element, in this case a transistor T1, which can be started by the microcomputer module via port G, is connected on the one hand to the power supply 10 and to the relay 17 on the other. The resistor R1 is also located parallel to the relay 17, and the holding current required for the ignition lock magnet 6 is much higher than the current flowing through the relay 17. The circuit also has two consecutively connected and timed safety interrupts 18, which are connected for control purposes to the microcomputer module via ports H and M.

Two additional circuit elements, transistor T2 and transistor T3, are tied to this circuit between the relay 17 and the safety interrupter 18. Transistor T2, with resistor R3 upstream of the transistor, is connected to the negative terminal of power source 10 and can be started by a microcomputer module through port F, while transistor T3 is power source 10. It is connected to the positive terminal of and can be started by the microcomputer module through the port (E).

Furthermore, the analog amplifier 20 is connected in parallel to the thermocouple 4. The analog amplifier 20 has a task of measuring, amplifying, and converting a direct current in the thermocouple 4 generated in the millivolt range into a range in which the microcomputer module can process. In this case the analogue amplifier 20 is designed as a direct current amplifier, since the conventional DC amplifier requires an auxiliary supply on the one hand over the operating voltage and on the other hand suffers a drift deviation due to, for example, the influence of temperature. .

The analog amplifier depicted in FIG. 3 is also described as follows:

Field effect transistor T4, initiated by the microcomputer module via port L and resistor R2, forms a controllable voltage divider. The preamp and booster amplifiers are downstream from the voltage divider, and blocking capacitors C4 and C5 are assigned to each of them.

With preamplifier V1, the reference potential is formed by a positive voltage to eliminate unstable fluctuations in the built-in voltage. On the other hand, in the case of the booster amplifier V2, the reference voltage is formed by mass. Since they do not operate when there is no need to save electricity, both the amplifiers (V1, V2) and the trigger (TR) are operated through the port (K) by the microcomputer module. The trigger TR behind the booster amplifier V2 is connected to the microcomputer module by port I as far as this is concerned.

To carry out this method, an ignition command is sent to the microcomputer module via the remote control. The analog amplifier 20 actuated by the port K checks whether the thermal electromagnetic force can withstand the thermocouple 4 and relevant information is provided to the microcomputer module via the port I. If there is an existing thermal electromagnetic force corresponding to the burning pilot light, the ignition procedure is canceled, but if there is no thermal electromagnetic force, the voltage divider of the analog amplifier 20 is initiated by the microcomputer module via port L. Switching the voltage divider once converts the direct current in the current thermocouple 4 into a pulse of alternating current. This pulse reaches the preamplifier V1 by the blocking capacitor C4. The signal from preamplifier V1 is connected to booster amplifier V2 via blocking capacitor C5 and further amplified. This analog signal from booster amplifier V2 is digitized by trigger TR at a fixed trigger point, which is shown in the diagram with reference to FIG.

This diagram plots the course of voltage U over time t. The trigger TR sets the initial trigger point TR1 when the pulse signal IS is introduced at time TL at the defined voltage level SE and the second trigger to which time TE is assigned at the voltage release of the pulse signal IS. Set the point TR2. The elapsed time between two points of time TL and TE is the measurement signal MS.

The measurement signal MS obtained from the existing thermal electromagnetic force reaches the microcomputer module via the port 1. The length of the measurement signal MS is directly proportional to the thermal electromagnetic force in the thermocouple 4.

If there is any thermal transfer force, that is, if the pilot light is already burning, the ignition procedure is canceled, while on the other hand if there is no thermal electromagnetic force the power oscillator 11 will be operated by the microcomputer module via port J. The storage capacitor C1 will be switched to the first stage 12 of the multiple cascade via port A.

Operating the power oscillator 11 begins to oscillate the resonant circuit across the feedback element. That is, the resonant circuit becomes the power oscillator 11 which vibrates by itself and determines the frequency. This means that at the output from the power oscillator 11 there is several times higher alternating current compared to the low direct current supplied by the battery at the input.

This alternating current is assisted by two cascade steps 12 and 13 until the element 14, which serves to monitor the voltage and limit the maximum voltage generated, reacts and sends a signal through the port D to the microcomputer module. Charge the storage capacitor C1 and the ignition capacitor C2, and then switch off the power oscillator 11 through the port J.

Thereafter, the periodic safety interrupter 18 is activated through the port M and the ignition lock magnet 6 is supplied with a holding current from the power supply 10 by the transistor T1 started through the port G and A voltage is applied to the relay 17 to open the circuit between the ignition lock magnet 6 and the thermocouple 4. The resonant circuit C1 is suddenly discharged by the subsequent trigger of the port B. Shortly thereafter, the resonant circuit C1 is separated in cascade step 12 via port A. The pulse magnet 5 is immediately energized by a sudden change in this power supply and the tappet 7 moves far enough against the force of the recoil spring 8 so that the anchor 3 is attached to the ignition lock magnet 6. do. Because of the flowing holding current, the anchor 3 is fixed and the ignition lock valve 2 is opened. The gas can flow through the gas control valve to the ignition burner 1.

After a period of time has elapsed, if a breakdown occurs due to a failure or the like of an element, the voltage application of the ignition lock magnet 6 via the power supply 10 may also be connected in series with one or more independent safety shut-offs 18. Will be impeded, and the ignition lock valve will not remain open and will be closed again by the recoil spring 8.

The microcomputer module operates the ignition device through port C, discharges the ignition capacitor C2 and pilot light flashes over the ignition electrode 9 to ignite the outflowing gas. After a predetermined period of time, approximately one second has elapsed in this embodiment, the analog amplifier 20 is activated through ports K and L, and the voltage can be sensed since heating is initiated as a result of combustion pilot light. This, ie at least approximately 1 mV, is checked to determine whether or not the thermocouple 4 has already been applied.

If this is not the case, an additional ignition procedure will be introduced, and as already explained above, the power oscillator 11 will be activated, while the ignition capacitor C2 will be charged and discharged again when new pilot light is generated. will be. With this next ignition procedure, the storage capacitor C1 is disconnected from the cascade step 12 to save power since it is no longer necessary to charge the storage capacitor C1. If the ignition of the gas does not occur for a certain period of time, the microcomputer module will cancel the ignition procedure.

If there is a minimum voltage, of course the further ignition procedure will no longer be started, but the available open circuit voltage of the thermocouple 4 is not until the amount of electrically calculated current is sufficient as the holding current for the ignition lock magnet 6. Will be checked again. Here, the analog amplifier 20 is stopped through the port K, and the current flowing from the power supply 10 to the ignition lock magnet 6 is disturbed by the port G. The relay 17 is not energized and the open and close contact of the relay 17 closes the circuit between the thermocouple 4 and the ignition lock magnet 6. The anchor 3 is now held by the thermocouple current.

In order to prevent the anchor 3 from dropping out due to the necessary brief interruption of the holding current when the retractable contact of the relay 17 is switched, the transistor T2 is switched through the port F simultaneously with the switching. Operating for a while, additional current is similarly generated by resistor R3 for a short time, safely preventing the anchor from dropping off as mentioned above.

When the gas control valve is switched off, a switch-off command is sent to the microcomputer module via the remote control. By briefly operating the ports G and E while bypassing the safety shut-off 18 and the ignition lock magnet 6, a sudden change in power is sent through the relay 17, the closing contact of which is consequently It is lifted up for a while. This prevents the holding current from flowing between the thermocouple 4 and the ignition lock magnet 6. The anchor is no longer held by the ignition lock magnet 6 and the ignition lock valve 2 is closed under the influence of the recoil spring 8. The gas flow towards the ignition burner 1 and the main burner (not shown) is disturbed and the gas flame is turned off.

The circuit device for carrying out the method and method, which is the subject of the present invention, is of course not limited to the described embodiments. Modifications or adaptations and combinations thereof are possible without departing from the scope of the invention.

It is clear that the transmission of the control signal can be by cable, infrared, radio waves, ultrasonic waves, etc. as is generally known. It is also possible that the remote control is not used and it is also possible that all the necessary components are at or within the gas control valve. There may also be only a main burner which is directly ignited. In addition, a small plug-in ignition supply may be used as the power source 10 instead of an easily pluggable battery.
