Description

Die Erfindung betrifft ein Gaskochfeld sowie ein Anzeigeverfahren für ein Gaskochfeld mit zumindest einem ersten und einem zweiten Gasbrenner mit jeweils einem zugeordneten Flammenüberwachungssensor, der bei einem Erlöschen einer Flamme von zumindest dem ersten Gasbrenner ein Hauptventil schließt, das in einer Hauptgasleitung angeordnet ist, die sich in zu den Gasbrennern führenden Teilgasleitungen teilt, in denen jeweils ein Einstellelement zur Einstellung eines Gasmengenstromes angeordnet ist, und mit einer Anzeigeeinrichtung, die nach dem Schließen des Hauptventils den ersten Gasbrenner anzeigt.The invention relates to a gas hob as well as a display method for a gas hob with at least a first and a second gas burner, each with an associated flame monitoring sensor which closes when a flame goes out of at least the first gas burner, a main valve which is arranged in a main gas line, located in to the gas burners leading partial gas lines, in each of which a setting element for adjusting a gas flow rate is arranged, and with a display device, which indicates the first gas burner after closing the main valve.

Aus EP 0 727 616 A1 ist ein gattungsgemäßes Gaskochfeld mit vier Gasbrennern bekannt. Jedem der Gasbrenner ist ein Flammenüberwachungssensor zugeordnet, der bei einem Erlöschen einer Flamme während eines Brennerbetriebs ein Hauptventil schließt, das in einer Hauptgasleitung angeordnet ist, die sich in zu den Gasbrennern führenden Teilgasleitungen teilt, in denen jeweils ein Gashahn zur Einstellung eines Gasmengenstromes angeordnet ist.Out EP 0 727 616 A1 is a generic gas hob with four gas burners known. Associated with each of the gas burners is a flame monitoring sensor which, when a flame extinguishes during a burner operation, closes a main valve located in a main gas line which divides into partial gas ducts leading to the gas burners, in each of which a gas tap for adjusting a gas flow rate is arranged.

US-A-6,164,958 zeigt die Merkmale des Oberbegriffs der Ansprüche 1 und 4. Zusätzlich ist eine Vielzahl anderen Sensoren, beispielsweise ein Rauchsensor, vorgesehen. Erfasst einer der Sensoren eine Anormalität, wie beispielsweise Rauch usw., zeigt ein Warnfeld eine Warnanzeige an. US-A-6,164,958 shows the features of the preamble of claims 1 and 4. In addition, a variety of other sensors, such as a smoke sensor, is provided. If one of the sensors detects an abnormality such as smoke, etc., a warning field displays a warning indication.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein Gaskochfeld mit Gasbrennern sowie ein Verfahren zur Anzeige in einem Gaskochfeld bereitzustellen, bei dem das Gaskochfeld auch bei einem fehlerhaften Erlöschen einer Flamme an einem Gasbrenner in sicherer Weise bedienbar ist.The object of the present invention is to provide a gas hob with gas burners and a method for display in a gas hob, in which the gas hob is reliably operated even with a faulty extinction of a flame on a gas burner.

Die Aufgabe der Erfindung ist durch ein Gaskochfeld bzw. durch ein Verfahren mit den Merkmalen des Anspruches 1 bzw. den Merkmalen des Anspruches 4 gelöst. Gemäß dem kennzeichnendem Teil des Anspruches 1 zeigt sinngemäß eine Anzeigeeinrichtung des Gaskochfeldes nach dem Schließen des Hauptventils nicht nur den Gasbrenner, dessen Flamme erloschen ist ist, sondern auch alle weiteren Gasbrenner, deren Einstellelemente sich in einer Offenstellung befinden. Durch die Anzeigeeinrichtung erhält ein Benutzer den Hinweis, welche Gasbrenner bis zum Erlöschen der Flamme in Betrieb waren. Deren Einstellelemente kann der Benutzer zunächst in eine Schließposition bringen, um zuverlässig einen unerwünschten Gasaustritt aus den Gasbrennern zu vermeiden. Anschließend kann in sicherer Weise ein darauffolgender Gaskochfeldbetrieb stattfinden.The object of the invention is achieved by a gas hob or by a method having the features of claim 1 and the features of claim 4. According to the characterizing part of claim 1 shows an analog display device of the gas hob after closing the main valve not only the gas burner whose flame is extinguished, but also all other gas burner whose Adjustment elements are in an open position. By the display device, a user receives the indication which gas burners were in operation until the flame went out. Their adjustment elements, the user can first bring into a closed position to reliably avoid unwanted gas leakage from the gas burners. Subsequently, a subsequent gas hob operation can safely take place.

Sicherheitstechnisch bevorzugt ist es, wenn die Anzeigeeinrichtung jeden Gasbrenner, dessen Einstellelement sich in der Offenstellung befindet, solange anzeigt, bis dessen Einstellelement wieder in der Schließstellung ist.From a safety point of view, it is preferred if the display device displays each gas burner, whose adjusting element is in the open position, until its adjusting element is in the closed position again.

Vorteilig kann die Anzeigeeinrichtung nach dem Zurückstellen der Einstellelemente aller im Betrieb befindlichen Gasbrenner nur noch den Gasbrenner anzeigen, dessen Flamme erlöscht ist. Somit erhält der Benutzer den Hinweis auf den defekten Gasbrenner erst, nachdem alle in der Offenstellung befindlichen Einstellelemente der Gasbrenner wieder in der Schließstellung sind.Advantageously, after resetting the adjusting elements of all the gas burners in operation, the display device can only display the gas burner whose flame has extinguished. Thus, the user receives the reference to the defective gas burner only after all adjusting elements of the gas burners in the open position are in the closed position again.

Nachfolgend wird ein Ausführungsbeispiel der erfindungsgemäßen Gaskochstelle anhand der beigefügten Figuren beschrieben. Es zeigen:

Hereinafter, an embodiment of the gas hob according to the invention will be described with reference to the accompanying figures. Show it:
FIG. 1
in a perspective view of a gas hob;
FIG. 2
a block diagram for a gas burner of the gas hob; and
FIGS. 3a to 3c
in a view from above a section of a control bar of the gas hob in the display and actuating elements of the gas hob are shown.

Das in der Figur 1 gezeigte Gaskochfeld weist vier schematisch angedeutete Gasbrenner 1, 3, 5, 7 auf, die durch eine Abdeckplatte 9 des Gaskochfelds geführt sind. Frontseitig weist das Gaskochfeld eine Bedienleiste 11 auf. In dieser ist für jeden der Gasbrenner jeweils ein Bedienknebel 13, 15, 17, 19 angeordnet. Weiterhin ist jedem der Gasbrenner eine Anzeige 21, 23, 25, 27 zugeordnet, die jeweils als LED ausgebildet ist. Nicht dargestellt sind der Figur 1 den Gasbrenner zugeordnete Topfträger für ein Abstellen von Gargutbehältnissen über den Gasbrennern.That in the FIG. 1 shown gas hob has four schematically indicated gas burner 1, 3, 5, 7, which are guided by a cover plate 9 of the gas hob. On the front side, the gas hob has a control bar 11. In each of these a gas knob 13, 15, 17, 19 is arranged for each of the gas burners. Furthermore, each of the gas burners is associated with a display 21, 23, 25, 27, which is in each case designed as an LED. Not shown are the FIG. 1 the gas burner associated pot carrier for parking Gargutbehältnissen on the gas burners.

Die Funktionsweise des Gaskochfeldes ist anhand des Blockschaltbilds der Figur 2 beschrieben. Aus Gründen der Übersichtlichkeit ist das Blockschaltbild der Figur 2 auf den Gasbrenner 1 mit dem zugeordneten Bedienknebel 13 sowie der Störanzeige 21 beschränkt. Die weiteren Gasbrenner 3, 5, 7 sind in entsprechender Weise in dem Gaskochfeld verschaltet. Für eine Flammenüberwachung ist dem Gasbrenner 1 gemäß der Figur 2 eine Ionisationselektrode 29 zugeordnet, mit der ein Vorhandensein einer Flamme des Brenners 1 erfasst wird. Mittels der Flamme kann ein Spalt zwischen der Flammenionisationselektrode 29 und dem Gasbrenner 1 elektrisch überbrückt werden, wodurch ein entsprechendes Signal von der Ionisationselektrode 29 über eine Signalleitung 31 zu einer elektronischen Steuereinrichtung 33 geleitet wird. Die elektrische Steuereinrichtung 33 ist über eine weitere Signalleitung 35 mit einem Hauptventil 37 in Verbindung. Das Hauptventil 37 ist in einer Hauptgasleitung 39 angeordnet, die an ein Gasversorgungsnetz gekoppelt ist. Ausgangsseitig ist das Hauptventil 37 mit einem Verteilerrohr 41 verbunden, von dem Teilgasleitungen 42 jeweils zu den Gasbrennern 1, 3, 5, 7 führen.The operation of the gas hob is based on the block diagram of the FIG. 2 described. For clarity, the block diagram is the FIG. 2 limited to the gas burner 1 with the associated control knob 13 and the fault indicator 21. The other gas burner 3, 5, 7 are in a corresponding manner in the Gas hob interconnected. For flame monitoring is the gas burner 1 according to the FIG. 2 associated with an ionization electrode 29, with the presence of a flame of the burner 1 is detected. By means of the flame, a gap between the flame ionization electrode 29 and the gas burner 1 can be electrically bridged, whereby a corresponding signal is passed from the ionization electrode 29 via a signal line 31 to an electronic control device 33. The electrical control device 33 is connected via a further signal line 35 with a main valve 37 in connection. The main valve 37 is arranged in a main gas line 39, which is coupled to a gas supply network. On the output side, the main valve 37 is connected to a distributor pipe 41, from which partial gas lines 42 each lead to the gas burners 1, 3, 5, 7.

In der Figur 2 ist lediglich der Gasweg zu dem Gasbrenner 1 vollständig dargestellt. In der zu dem Gasbrenner 1 führenden Teilgasleitung 42 ist ein Gashahn 45 angeordnet, mit dem ein Gasmengenstrom zum Gasbrenner 1 eingestellt wird. Dessen Schaltwelle 47 ist über ein Schaltgestänge 49 mit dem Drehknebel 13 verbunden. Zwischen dem Schaltgestänge 49 und dem Drehknebel 13 ist ein Signalgeber 51 geschaltet. Der Signalgeber 51 erfasst eine Drehposition des Drehknebels 13 und gibt diese über eine Leitung 53 an die elektronische Steuereinrichtung 33. In entsprechender Weise werden die Drehpositionen der weiteren Bedienknebel 15, 17, 19 über die mit gestrichelter Linie angedeuteten Signalleitungen zur elektronischen Steuereinrichtung 33 geleitet. Über die elektronische Steuereinrichtung 33 ist die Störanzeige 21 des Gasbrenners 1 ansteuerbar.In the FIG. 2 only the gas path to the gas burner 1 is shown completely. In the leading to the gas burner 1 partial gas line 42, a gas cock 45 is arranged, with which a gas flow rate to the gas burner 1 is set. Its switching shaft 47 is connected via a shift linkage 49 with the rotary knob 13. Between the shift linkage 49 and the rotary knob 13, a signal generator 51 is connected. The signal generator 51 detects a rotational position of the rotary knob 13 and outputs it via a line 53 to the electronic control device 33. In a corresponding manner, the rotational positions of the further control knob 15, 17, 19 directed via the indicated by dashed lines signal lines to the electronic control device 33. About the electronic control device 33, the fault indicator 21 of the gas burner 1 is controlled.

Zum Start eines Brennerbetriebs wird gemäß der Figur 2 der Bedienknebel 13 zunächst aus seiner Nullstellung gedreht, in der sich der Gashahn 45 in einer Schließstellung befindet. Diese Anfangsdrehung wird durch den Signalgeber 51 erfasst, der ein entsprechendes Signal an die elektronische Steuereinrichtung 33 leitet. Daraufhin öffnet die elektronische Steuereinrichtung 33 das normalerweise geschlossene Hauptventil 37, so dass über die Hauptgasleitung 39 und die Teilgasleitung 42 ein Gasmengenstrom dem Gasbrenner 1 zugeführt wird. Gleichzeitig steuert die elektronische Steuereinrichtung 33 die Ionisationselektrode 29 an, um den Gasbrenner 1 zu zünden. Eine Einstellung des Gasmengenstroms zum Gasbrenner 1 erfolgt mittels des Gashahns 45. Dessen Strömungsquerschnitt kann über den Bedienknebel 13 entsprechend verändert werden.To start a burner operation is in accordance with the FIG. 2 the control knob 13 is first rotated from its zero position, in which the gas tap 45 is in a closed position. This initial rotation is detected by the signal generator 51, which passes a corresponding signal to the electronic control device 33. Subsequently, the electronic control device 33 opens the normally closed main valve 37, so that via the main gas line 39 and the partial gas line 42, a gas flow rate is supplied to the gas burner 1. At the same time, the electronic controller 33 controls the ionization electrode 29 to ignite the gas burner 1. An adjustment of the gas flow rate to the gas burner 1 by means of the gas tap 45. Its flow cross section can be changed accordingly via the control knob 13.

Während des Betriebes des Gasbrenners 1 ist die LED-Anzeige 21 dauerhaft eingeschaltet.During operation of the gas burner 1, the LED display 21 is permanently switched on.

In den Figuren 3a bis 3c ist die Bedienleiste 11 mit den Bedienknebeln 13 bis 19 sowie den Anzeigen 21 bis 27 dargestellt. Gemäß der Figur 3a sind die drei Gasbrenner 1, 3, 5 in Betrieb. Demgemäß sind die zugeordneten Bedienknebel 13, 15, 17 aus ihrer Nullstellung gedreht. Die zugeordneten LED-Anzeigen 21 sind dauerhaft erleuchtet, so dass für dem Benutzer klar ersichtlich ist, dass die Gasbrenner 1, 3, 5 in Betrieb sind. Der Bedienknebel 19 des Gasbrenners 7 ist dagegen in seiner Nullstellung und seine zugeordnete LED-Anzeige 21 ist ausgeschaltet. D.h., dass für den Benutzer klar ersichtlich ist, dass der Gasbrenner 7 außer Betrieb ist.In the FIGS. 3a to 3c is the control bar 11 with the control knobs 13 to 19 and the displays 21 to 27 shown. According to the FIG. 3a are the three gas burners 1, 3, 5 in operation. Accordingly, the associated control knob 13, 15, 17 are rotated from its zero position. The associated LED displays 21 are permanently lit, so that it is clear to the user that the gas burners 1, 3, 5 are in operation. The control knob 19 of the gas burner 7, however, is in its zero position and its associated LED display 21 is turned off. That is, it is clear to the user that the gas burner 7 is out of operation.

In den Figuren 3b und 3c wird von dem Fall ausgegangen, dass die Flamme am Gasbrenner 1 fehlerhaft während des Brennerbetriebs erlischt. Ein solches Erlöschen der Flamme erfolgt bspw. aufgrund von Garflüssigkeit, die auf den Brenner 1 tropft. Ein solches Erlöschen der Flamme wird durch zugeordnete Flammenionisationselektrode 29 erfasst, so dass ein entsprechendes Signal an die elektronische Steuereinrichtung 33 geleitet wird. Die elektronische Steuereinrichtung 33 steuert die Flammenionisationselektrode 29 an, damit der Gasbrenner 1 für ein wiederentzündet wird. Sofern eine solche Wiederentzündung des Gasbrenners 1 erfolglos bleibt, schließt die elektronische Steuereinrichtung 33 das Hauptventil 37. Dadurch ist die Gaszufuhr zu allen Gasbrennern der Gaskochstelle unterbrochen. Gleichzeitig steuert die elektronische Steuereinrichtung 33 die LED-Anzeigen aller Gasbrenner 1, 3, 5 an, deren Gashähne 45 sich nach dem Schließen des Hauptventils 37 noch in einer Offenstellung befinden. Vorliegend steuert die Steuereinrichtung 33 die LED-Anzeigen 21, 23, 25 an. Die LED-Anzeigen 21, 23, 25 beginnen daher zu blinken, wie in der Figur 3b angedeutet sein soll. Dadurch erhält der Benutzer einen Hinweis darauf, welche Gasbrenner bis zum Erlöschen der Flamme des Gasbrenners 1 in Betrieb gewesen sind bzw. die Gashähne 45 welcher Gasbrenner noch offen sind.In the FIGS. 3b and 3c it is assumed that the flame on the gas burner 1 goes off incorrectly during burner operation. Such extinction of the flame takes place, for example, due to cooking liquid dripping onto the burner 1. Such extinction of the flame is detected by associated flame ionization electrode 29, so that a corresponding signal is sent to the electronic control device 33. The electronic controller 33 controls the flame ionization electrode 29 to cause the gas burner 1 to be re-ignited. If such a reignition of the gas burner 1 is unsuccessful, the electronic control device 33 closes the main valve 37. As a result, the gas supply to all gas burners of the gas hob is interrupted. At the same time, the electronic control device 33 controls the LED displays of all gas burners 1, 3, 5, whose gas taps 45 are still in an open position after closing the main valve 37. In the present case, the control device 33 activates the LED displays 21, 23, 25. The LED displays 21, 23, 25 therefore start to flash, as in FIG FIG. 3b should be indicated. This gives the user an indication of which gas burners have been in operation until the flame of the gas burner 1 extinguished or the gas taps 45 which gas burners are still open.

Damit der Benutzer das Gaskochfeld erneut in Betrieb setzen kann, müssen wegen Sicherheitsgründen zunächst die noch offenen Gashähne 45 in ihre Schließstellung zurückgestellt werden. Solange dies nicht der Fall ist, blinken die den Gasbrennern 1, 3, 5 zugeordneten LED-Anzeigen 21 bis 25 weiter. Nachdem alle Gashähne 45 mittels der Bedienknebel 13, 15, 17 in ihre Schließstellung gebracht sind, blinkt nur noch die LED-Anzeige 21, die dem Gasbrenner 1 zugeordnet ist, wie es in der Figur 3c dargestellt ist. Hierdurch erhält der Benutzer einen Hinweis darauf, dass am Gasbrenner 1 die Flamme ein fehlerhaft erlöscht ist.So that the user can put the gas hob back into operation, for safety reasons, the still open gas taps 45 must first be returned to their closed position. As long as this is not the case, the gas burners 1, 3, 5 associated LED displays 21 to 25 continue to flash. After all gas taps 45 by means of Control knob 13, 15, 17 are brought into their closed position, only flashes the LED display 21, which is associated with the gas burner 1, as shown in the Figure 3c is shown. This gives the user an indication that the flame on the gas burner 1 is defective.

Wenn alle Gashähne 45 wieder in ihrer Schließstellung sind, wie in der Figur 3c der Fall ist, können die verbleibenden funktionsfähigen Gasbrenner 1, 5, 7 des Gaskochfeldes erneut in Betrieb genommen werden. Das in der Figur 3c dargestellte Blinken der LED-Anzeige 23 des Gasbrenners 3 kann zeitlich begrenzt sein.When all gas taps 45 are in their closed position again, as in the Figure 3c If this is the case, the remaining functioning gas burners 1, 5, 7 of the gas hob can be put into operation again. That in the Figure 3c shown flashing of the LED display 23 of the gas burner 3 may be limited in time.
