    The invention relates to a method for controlling a heating device with a combustion chamber, as indicated in claim 1.
    Simple, rigid control concepts are known from the prior art, which after each opening and closing of the combustion chamber door of a heater assume that new fuel has been introduced into the combustion chamber. However, if this has not been the case, for example because a user of the heater has only briefly looked around without introducing new fuel into the combustion chamber, the control assumes a wrong situation in the combustion chamber and the combustion is deficient.
    Furthermore, EP 0 985 883 A2 discloses heaters which are suitable for at least two types of fuels, and wherein a first type of fuel can be introduced via the combustion chamber door and a second type of fuel can be introduced automatically into the combustion chamber of the heating device via a feed device.
    The present invention has for its object to provide a method for controlling a heater with a combustion chamber, which increases the efficiency of the combustion process, especially in the introduction of new fuel into the combustion chamber and thereby causes the least possible additional effort and / or an additional, practical Benefit to the operator of the heater offers.
    This object of the invention is achieved by a method according to claim 1.
    According to the invention, the control of the heating device during the operating phase with a first sensor continuously monitors the opening and closing of the combustion chamber door of the heating device. This continuous monitoring of the combustion chamber door is possible in a simple and reliable manner, in particular with a mechanical-electrical sensor, such a sensor having a long service life. By detecting the opening and closing operations of the combustion chamber door, the Re- Ν2011 / 0Θ500
    4V • · • ♦ · -2-gelung the heater, the potential times at which new fuel, especially logs, was introduced via the need to open the combustion chamber door into the combustion chamber, already strong. It is essential that it is determined after closing the combustion chamber door with at least one other sensor, if really new fuel was introduced into the combustion chamber. The assumption that new fuel is introduced into the combustion chamber each time the combustion chamber door is opened and closed is not always correct. Thus, assuming that new fuel is always present in the combustion chamber after opening and closing the combustion chamber door, and if the control settings of the heater are adjusted or changed, then in those cases where no new fuel is actually entering the combustion chamber was introduced, the control of the heater set incorrectly and there is a lack of combustion. If, however, it is determined with the at least one further sensor whether new fuel has been introduced into the combustion chamber, the control setting of the heating device can be reliably and correctly adapted to the respectively prevailing situation. In particular, the control of the heater can be set differently, depending on whether a new fuel has been introduced into the combustion chamber or not. This results in a more optimal combustion process in the different situations result, on the one hand, a higher energy yield and heat output at the same amount of fuel and on the other hand a lower pollutant or Ascheerrtwicklung is achieved during the firing process.
    The procedure according to the invention thus makes it possible in a simple manner to optimize or adapt the combustion process in a heating device, especially in the phases in which really new fuel is introduced into the combustion chamber and thus the combustion conditions in the combustion chamber are changed. Of advantage here are the measures according to claim 2, since in particular by an at least short-term increase in the air supply into the combustion chamber of the combustion process is accelerated when new fuel was introduced into the combustion chamber. Increasing the air supply optimizes the firing or ignition process for the newly attached fuel and at the same time ensures that the lowest possible amount of additional exhaust gases and soot particles is formed in this firing process. In addition to a reduction in the environmental impact of the operation of the heater is thereby also about a sooting of the combustion chamber, a possibly present, sealed with glass sight opening and / or the flue gas guide means inferred. If the combustion chamber door of the heating device is opened and closed, but no new fuel is introduced into the combustion chamber, this is done by the at least one further sensor detected and the Regeiungseinsteliun gene relating to the air supply into the combustion chamber are kept substantially the same. This prevents, for example, that accelerated burning of the fuel already present in the combustion chamber is triggered by the increased air supply, whereby the burning time of the fuel would be relatively greatly reduced, the heating device would be relatively highly heated and the combustion process would not proceed optimally.
    Of particular advantage are the measures according to claim 3, since the use of a temperature sensor is a very simple and cost-effective way to determine a successful introduction of new fuel into the combustion chamber. Such introduction of new fuel into the combustion chamber can be determined by means of a temperature sensor in particular by the fact that after closing the combustion chamber door, the temperature rises in the combustion chamber. The basically maintenance-free temperature sensor, which can also be based on many different, long-matured operating principles, also offers additional, practical benefits for the operation of the heater. For example, the temperature data of the sensor can also be used simultaneously for the exact determination of the actual heating power of the heating device. Likewise, these temperature data can be used as an input parameter for a control to optimize the combustion process, such as to optimize the air supply into the combustion chamber.
    The measures according to claim 4 are also advantageous, since a carbon monoxide sensor (CO sensor) quickly and reliably provides information as to whether new fuel has been introduced into the combustion chamber or not. This can be established in particular on the basis of the fact that after the introduction of new fuel into the combustion chamber and after closing the combustion chamber door, the CO content in the combustion chamber increases at least in the short term, since when igniting the newly added fuel partially incomplete combustion occurs. Based on the ideal CO content in the flue gases produced during combustion, which is approximately 30 ppm under optimum and stable combustion conditions, the CO content in the flue gas increases after the introduction of new fuel into the combustion chamber Sensor is detected. In addition, the use of a CO sensor for the operator of the heater provides an additional, practical benefit, since the reliability of the heater can be improved in a simple and reliable manner. In particular, the CO content in the flue gas N2011 / 06500 -4 can be monitored continuously with the CO sensor and, if a certain limit value is exceeded, countermeasures initiated in order to avert risks to the health and life of the user of the heating device. In addition, the measured value for the CO content in the flue gas can also be used as input parameter for a control for optimizing the combustion conditions in the heating device, whereby a very high degree of optimization of the combustion process can be achieved.
    Particularly advantageous is an embodiment according to claims 5 or 6, since thereby the efficiency of the combustion process is increased in heaters, soft at least a first fuel via a need to open the combustion chamber door into the combustion chamber of the heater is introduced and at least one further fuel with an automatic Feeding means is introduced into the combustion chamber. In particular, the efficiency of a heating device can be increased by the described measures, in which as the first, be supplied through the combustion chamber door fuel logs and as another, automatically supplied fuel Holzpetiets use. On the one hand, it is ensured that in pellet operation, in which new pellets are automatically introduced as required and caused by the regulation of the heating means by means of the Zufüh-medium in the combustion chamber, the introduction of firewood through the combustion chamber door in the combustion chamber, the control of the heater in the Log operation changes, the automatic supply of wood pellets in the combustion chamber ends at the latest after the successful firing of newly introduced firewood and adjusts the control settings, so that the ignition or, subsequently, the burning of newly introduced firewood runs under optimal conditions. This increases the efficiency of the combustion process in the heater. Furthermore, such an increase in efficiency in log operation of the heater is achieved because it is determined by the at least one other sensor on reliable way and catfish, whether actually new logs is introduced into the combustion chamber and thus remains in the log operation and the control setting of the heater to ensure optimum Inflammation process of the newly added log to be adjusted whether the control setting of the heater are kept substantially the same because no new firewood was introduced into the combustion chamber or whether the Scheltholzbetrieb in the pellet mode is changed after the heating power of the heater under a certain, in particular by the user Value has dropped. N2011 / 06500 * «· * • 4 * -5-
    The regulation of the heating device can therefore reliably and simply monitor any supply of fuel into the combustion chamber. This includes not only the automatic supply of the additional fuel via the Zuführmitte], which is indeed caused by the regulation of the heater itself, but also the introduction of a first fuel into the combustion chamber, as this is determined with the at least one other sensor. Thus, the combustion conditions in the combustion chamber of the control of the heater can be optimally adapted to the prevailing situation, depending on whether a new first fuel was introduced into the combustion chamber or not.
    Another advantage is the measures according to claim 7, since this ensures that no disturbing logs or ash residues remain in the pellet burner and could hinder the ignition or burning of HoJzpellets in pellet operation, whereby the efficiency of the combustion process in pellet operation would be impaired.
    In the measures according to claim 8 is advantageous that when changing from log-wood operation in the pellet operation of the tipping is only dumped when a large part of the possibly still present in the combustion chamber firewood is burned and thus no fuel is wasted.
    In the measures according to claim 9 is of advantage that on the one hand an efficient commissioning of the heater is ensured in the pellet and the operator of the heater at the same time a high degree of comfort is offered, and on the other in the following on the start phase of the heater operating phase efficient combustion process is ensured, as is changed reliably depending on the actual addition of firewood between pellet operation and firewood operation.
    Finally, the measures according to claim 10 are advantageous because an efficient combustion is ensured both during firing or ignition and during the burning of each introduced fuel and the control settings are really only changed when actually new fuel into the combustion chamber Heating device was introduced.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10. In Fig. 1, an embodiment of a heating device 1, which can be controlled according to the method according to the invention, illustrated by way of example The housing of the heater 1 is included not completely shown for reasons of clarity.
    According to the illustrated embodiment, the heating device 1 comprises a bottom element 2, on which a furnace element 3 is mounted, so that the heating device 1 aulweist a high stability. The furnace element 3 comprises a combustion chamber 4 open to the front, wherein the forwardly directed opening of the combustion chamber 4 is closed with a combustion chamber door 5 which can be opened as required. In particular, the combustion chamber door 5 can be provided with a glass pane 6 which provides a view into the combustion chamber 4 when closed Firing chamber door 5 releases and allows for improved space heating due to heat radiation. About the combustion chamber door 5, a new, in its dimensions relatively large first fuel, in particular firewood, in the combustion
    N2011 / O65QG ft ft. Ft. *· * ♦ * * * * * f 4 ft ft 1 are introduced. It should be explicitly stated at this point that "new fuel" always means the "fuel newly introduced into combustion chamber 4". Each opening and closing of the combustion chamber door 5 is registered by means of a first sensor 7 and reported to the control of the heating device 1. The first sensor 7 is designed in the present case as a mechanical-electrical end button, which is triggered by the lower portion 8 of the combustion chamber door 5.
    The introduced via the combustion chamber door 5 into the combustion chamber 4 logs is deposited on the grate support 9 and burned there. As best seen in the sectional view of the heater 1 in Fig. 2, in the central region of the grate support 9 a PeJ-10-burner trough 10 is formed, which in its depth extent starting from the grate support 9 extends down. The tipping grate 11 is provided on the one hand with small openings 12, so that the ashes obtained during combustion can continuously fall from the combustion chamber 4 into an ash tray arranged thereunder. In order to remove the ash tray from the furnace element 3 for emptying, the combustion chamber door 5 is equipped with a lower portion 8, via which the ash tray after opening the combustion chamber door 5 is accessible. Furthermore, the tipping grate 11 is rotatably mounted via a shaft 13, so that ash and other materials located in the pellet burner trough 10 can be tipped over a signal of the control of the heater 1 in the ash tray.
    In order to be able to automatically introduce a further fuel, which is relatively small in terms of its dimensions, into the combustion chamber 4 of the heating device 1, the heating device 1 is equipped with a supply means 14. The supply means 14 has, in particular, a screw conveyor 15 and a funnel 16, which are designed to convey wood pellets into the pellet burner 10 of the combustion chamber 4. The supply and the ignition of the wood pellets in the pellet burner 10 are controlled by the control of the heater 1. The wood pellets are stored in a reservoir, not shown, preferably formed above the hopper 16.
    In order to set the optimal combustion conditions, the heater 1 is equipped with a continuously variable ventilation device 17. The control of the heater 1 is via the ventilation device 17 according to the situation in the combustion chamber 4 and according to user specifications, the air supply into the combustion chamber 4 N2011 / 06500 -8- and in particular in the pellet burner 10 a. Oie primary air flows in particular from below into the pellet burner 10 and is preferably used in the ignition and burning of wood pellets and igniting logs. The secondary air flows downwards, in particular from above, on the inside of the combustion chamber door 5, thereby keeping the inside of a glass pane 6 which may be present free of soot deposits and the like. The secondary air is preferably used when firing logs.
    The resulting during combustion in the Brsnnraum 4 flue gas is passed through an opening 18 in the upper region of the combustion chamber 4 in flue gas guide means 19 and further discharged, for example, in the fireplace of a house. The removal of the flue gas is in the illustrated Ausführungsbeispie! supported by a suction device 20, so that the flue gas guiding means 19 can extend, for example, in the entire back region 21 of the furnace element 3.
    Since the described heating device 1 is usually used as a freestanding stove for heating a room via air convection or heat radiation, the furnace element 3 is equipped on its outside with heat exchanger elements 22, 23, whereby the efficiency of the heater 1 is increased.
    According to the exemplary visualization of the inventive method for controlling the heater 1, which is shown in Fig. 3, the heater 1 is automatically taken by the control in a start phase 24 by the ignition of wood pellets in the Peiletbrennmulde 10 in operation. This provides increased comfort for a user of the heater 1 and after successful completion of the starting phase 24, that is, after the wood pellets have been ignited in the Peiletbrennmulde 10, the control of the heater 1 changes to an operating phase, in which after addition of firewood between Peiletbetrieb 25th and log operation 27 is changed, in an alternative, not shown procedure, the user of the heater 1 can already decide at startup whether the heater 1 automatically and exclusively by the ignition of wood pellets or with the help of the user by the ignition of firewood put into operation is, in the latter case, but it is also appropriate to support the ignition of the billets by introducing at least a small amount of wood pellets in the Peiletbrennmulde 10. N2011 / 06500
    After the successful completion of the start phase 24 and the change to the normal operating phase of the heater 1 is in pellet mode 25 of the control of the heater 1 by means of the feeding means 14 wood pellets transported into the pellet burner 10 and burned. In accordance with the control settings and the user's specifications, the control of the heating device 1 controls the supply of wood pellets and air by means of the ventilation device 17 into the combustion chamber 4 in particular so that a certain room temperature is reached or maintained. If the heater is stopped by the user, no more wood pellets are fed into the combustion chamber 4 and after the burning of the wood pellets still in the combustion chamber 4, the heater 1 is taken out of service.
    If an opening and subsequent closing of the combustion chamber door 5, in particular also immediately after completion of the starting phase 24, is detected in the pellet operation by the first sensor 7 -see FIG. 1 -the measured values of the at least one further sensor 26 are evaluated. The further sensor 26 is shown in FIG. 2 and can be embodied, in particular, as a temperature sensor or as a CO sensor. Conveniently, the further sensor 26 is located in the middle or upper region of the combustion chamber 4, in particular on or in the rear wall of the Ofeneiements 3. However, it is also a Aus-guide form conceivable in which the further sensor 26 is located in the flue gas guide means 19. An advantage would be that the further sensor 26 would not be under the direct action of fire and would thus be exposed to less stress or less wear. If now the regulation of the heating device 1 via the weathered sensor 26 determines that no new firewood has been introduced into the combustion chamber 4 after closing the combustion chamber door 5, then the control settings of the heating device 1 are kept essentially the same. This relates in particular to the air supply into the combustion chamber 4 via the ventilation device 17, which air supply is not significantly changed in this case. A temperature sensor detects an opening and closing of the combustion chamber door 5 without introducing logs by the fact that after closing the combustion chamber door 5, the temperature does not rise higher than it was before opening the combustion chamber door 5. With a CO sensor, this circumstance can be determined by the fact that, after closing the combustion chamber door 5, the CO content in the combustion chamber 4 returns to the value which prevailed in the combustion chamber 4 before the combustion chamber door 5 was opened.
    If now the other case 26 detects the other case, namely that logs were introduced into the combustion chamber 4, then the regulation of the heating device 1 changes N2011 / 06500, t ····· * · * ······· · · SII · · · · ··· * * * * * * * * * * * * * * * * · · · < The introduction of firewood over the combustion chamber door 5 into the combustion chamber 4 can be fixed by the control in different ways depending on the embodiment of the further sensor 26. For a temperature sensor, the determination is based on the effect that after insertion of firewood and after the closing of the combustion chamber door 5, the temperature rises in particular over the value that had prevailed before opening the combustion chamber door 5 in the combustion chamber 4. In the case of a CO sensor, the detection takes place on the basis of the process that, after the introduction of firewood and after the closing of the combustion chamber door 5, the CO content increases, in particular at least in the short term, above the value prevailing in the combustion chamber before opening the combustion chamber door 5.
    After the change from pellet operation 25 in the log operation 27, the automatic pellet feed is stopped via the supply means 14 in the pellet burner 10 of the combustion chamber 4 at the latest after the successful ignition of newly introduced firewood, as long as the heater 1 reaches the particular desired by the user heating power. Furthermore, immediately after the change of the operating mode, the air supply into the combustion chamber 4 is increased via the ventilation device 17, in order to enable an optimal and rapid ignition of the newly introduced billet.
    It is particularly useful if, after the introduction of logs from the pellet plant 25 in the firewood operation 27 is changed and still pellets are fed into the combustion chamber 4 for a short time to allow a quick and comprehensive firing of the newly added firewood. This is especially necessary when the new log has not been optimally loaded into the combustion chamber 4, so that the fire from the pellet burner 10 can be difficult to propagate to the new log. This is particularly the case when the new log has not been positioned directly over the opening in the grate pad 9, which leads into the underlying pellet firing guide 10. After the newly introduced billet has been fully ignited and when sufficient logs have been introduced into the combustion chamber 4 to reach the user desired heating line, the automatic feed of pellets into the pellet burner 10 in log mode 27 is completely adjusted.
    According to a particularly advantageous embodiment, it is also determined in log firing operation 27 by means of the at least one further sensor 26 when opening and closing the combustion chamber door 5, whether new firewood has been introduced into the combustion chamber 4 or not. If it is determined that new billets have been introduced into the combustion chamber 4, then it is expedient to adapt at least the supply of air into the combustion chamber 4 in such a way that a reliable and rapid ignition of the newly introduced billet is made possible. It is also expedient, if necessary, to supply a small amount of pellets into the pellet burner trough 10 in order to accelerate or optimize the firing process of the newly introduced firewood.
    If it is determined in log operation 27 after opening and closing of the combustion chamber door 5 that no new firewood has been introduced into the combustion chamber 4, then the control settings of the heating device 1 and in particular the settings relating to the air supply into the combustion chamber 4 are substantially retained. If now at least a large part of the introduced into the combustion chamber 4 firewood burned in Scheft wood operation 27 or the heating power of the heater 1 below a certain, in particular by the user specified heat output and no new firewood was introduced, the control of the heater 1 changes from Log operation 27 back into the pellet operation 25 and wood pellets with the feed means 14 are automatically introduced into the pellet burner trough 10 and burned. According to an alternative, not shown embodiment of the control method can also be specified by the user that after the switch from firewood operation 27 back into the pellet 25 no automatic supply of wood pellets is performed more, but the heater is taken out of service or stopped.
    According to a particularly advantageous embodiment, the pellet burner 10 is equipped with a tilting 11, which is tilted when switching from Scheithotz 27 back into the pellet mode 25 so that disturbing logs or ash residues are removed from the pellet burner 10 before new wood pellets from the automatic feed means 14th be introduced into the Petletbrennmulde 10. Preferably, the tilting of the tilting crop 11 of the pellet burner 10 during the change from firewood operation 27 into the pellet cycle 25 is carried out only when the temperature falls below a temperature threshold and / or falls below a certain CO content in the combustion chamber 4 in order to completely burn off the fuel materials present in the pellet burner 10 to ensure. The determination of the Abkippzeitpunktes takes place in particular via the measured values of the at least one further sensor 25, which is preferably designed as a temperature sensor or a CO sensor. According to a particularly expedient, not shown embodiment, several such sensors 26 are integrated in the heating device 1, so that about the introduction of logs N2011 / 06500 Μ * · · · * · «« # · * · * * * * * »· In the combustion chamber 4, the instantaneous heat output of the heating device 1 and / or the tilting time of the tilting chop 11 can be determined even more accurately ,
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the heating device, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
