Gasgeräte mit elektronischer Temperaturregelung haben neben höheren Kosten den entscheidenden Nachteil, dass sie bei Stromausfall nicht benutzt werden können. Für kostengünstigere und stromunabhängige Gasgeräte werden Gasregelgeräte mit flüssigkeitsgefülltem Temperaturfühler verwendet. off. For gas appliances, this display is only available for devices that use an electronic temperature control. In addition to higher costs, gas appliances with electronic temperature control have the distinct disadvantage that they can not be used in the event of a power failure. For more cost-effective and independent gas appliances, gas controllers with liquid-filled temperature sensors are used.
Im Gegensatz zu den Gasregelgeräten mit elektronischer Temperaturregelung ist es bei Gasregelgeräten mit flüssigkeitsgefülltem Temperaturfühler nicht ohne weiteres möglich, die IST-Temperatur mit dem eingestellten Sollwert zu In contrast to gas controllers with electronic temperature control, it is not easily possible for gas controllers with liquid-filled temperature sensors to set the actual temperature with the set setpoint

Erfindungsgemäß wird das Problem dadurch gelöst, dass die an einem Ausgang des Gasregelgerätes zum Gasbrenner verbundene Einrichtung aus einem According to the invention the problem is solved in that the connected to an output of the gas control device to the gas burner means of a
Gehäuse besteht, die mindestens zwei miteinander verbundene Kammern aufweist, die durch eine einseitig mit einem elektrisch leitenden Bauteil Housing consists, which has at least two interconnected chambers, by a one-sided with an electrically conductive component
verbundenen Membran gasdicht getrennt sind, wobei die Kammer A mit dem Gasausgang des Gasregelgerätes verbunden ist, die Membran durch eine connected membrane gas-tight, wherein the chamber A is connected to the gas outlet of the gas control device, the membrane by a
Öffnung in der Kammer A bei geöffnetem Gasventil mit dem Gasdruck des Gasbrenners beaufschlagt einen Hub erzeugt, die Kammer B, in der die Seite der Membran mit dem verbundenen elektrisch leitenden Bauteil positioniert ist, durch den Hub über nach außen geführte Kontaktelemente einen Stromkreis schließt und den Betriebsstatus in geeigneter Weise anzeigt. Opening in the chamber A when the gas valve is open with the gas pressure of the gas burner applied produces a stroke, the chamber B, in which the side of the diaphragm is positioned with the connected electrically conductive member, closes a circuit through the hub via outwardly guided contact elements and the Operating status displays in a suitable manner.
Bei geschlossenem Gasventil geht der Hub der Membran mit der ihr eigenen Federsteifigkeit in die Ausgangstage zurück. Der Stromkreis öffnet und es wird kein Betriebsstatus mehr anzeigt. When the gas valve is closed, the stroke of the diaphragm with its own spring stiffness returns to the starting days. The circuit opens and no operating status is displayed.
Damit wurde eine Lösung gefunden, mit der die weiter oben genannten Nachteile des Standes der Technik beseitigt werden. Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor. Thus, a solution was found with which the above-mentioned disadvantages of the prior art are eliminated. Advantageous embodiments of the invention will become apparent from the dependent claims.
So erweist es sich als günstige Ausgestaltung der Einrichtung, dass die Kammer A des Gehäuses abweichend mit zwei Verbindungsstellen ausgeführt ist, um angeschlossen an den Zündgasausgang in der Zuführungsleitung zwischen Gasregelgerät und Zündgasbrenner als Statusanzeige des Zündgases zu dienen. Thus, it proves to be a favorable embodiment of the device that the chamber A of the housing is designed differently with two connection points to serve connected to the Zündgasausgang in the supply line between the gas regulator and Zündgasbrenner as a status indicator of the ignition gas.
Eine weitere günstige Ausgestaltung der Einrichtung ist, wenn die Kammer A des Gehäuses, die mit zwei Verbindungsstellen ausgeführt ist, als Fitting in der Zuführungsleitung zwischen Gasregelgerät und Gasbrenner angeordnet ist. Another advantageous embodiment of the device is when the chamber A of the housing, which is designed with two connection points, is arranged as a fitting in the supply line between the gas regulator and gas burner.
Eine andere mögliche Ausgestaltung besteht darin, wenn statt Anschluss einer Statusanzeige ein Relais an der Kontaktierung angeschlossen wird, das wiederum externe Komponenten abhängig schalten kann. Another possible embodiment is when instead of connecting a status display, a relay is connected to the contact, which in turn can switch external components dependent.
Aufgrund das die Membran eine Federsteifigkeit aufweist, die bei ausreichendem Hub den Einsatz einer separaten Rückstellfeder zum öffnen des Stromkreises beim Schließen des Gasventils des Gasregelgerätes erübrigt, führt zu einer weiteren günstigen Ausgestaltung. Due to the fact that the membrane has a spring stiffness, which does not require the use of a separate return spring for opening the circuit when closing the gas valve of the gas control device with sufficient stroke, leads to a further advantageous embodiment.
Der einfache Aufbau und die Funktionsweise der Einrichtung bedingen, dass eine an die Einbausituation angepasste Druckeinstellung der Einrichtung nicht notwendig ist. The simple structure and operation of the device require that adapted to the installation situation pressure adjustment of the device is not necessary.

Modified inventive device 1a, shown in Fig. 5, is installed in the Zündgaszuführungsleitung 13. Their electrical contact elements 10 are electrically connected to the voltage source 11 and the LED 12a.
Wie in Fig. 2 dargestellt, besteht die erfindungsgemäße Einrichtung 1 aus einem Gehäuse 14 mit zwei miteinander verbundenen Kammern, der Kammer A 17 und der Kammer B 19. Die Kammer A 17 aus sicherheitstechnischen Gründen aus metallischem Werkstoff, ist mit dem Gasausgang 7a des Gasregelgerätes 4 verbunden, in diesem Ausführungsbeispiel durch eine im Gewinde dichtende Verschraubung 25. Als Alternative Verbindung zur Gasregeleinrichtung kann mittels modifizierter Kammer A 17a eine Verschraubung mit zylindrischem As shown in Fig. 2, the device 1 of the invention consists of a housing 14 with two interconnected chambers, the chamber A 17 and the chamber B 19. The chamber A 17 for safety reasons of metallic material is connected to the gas outlet 7a of the gas control device 4 connected, in this embodiment, by a thread-sealing screw 25. As an alternative connection to the gas control device can by means of modified chamber A 17a a screw with cylindrical
Gewinde 27 und einem Dichtelement 26, wie in Fig. 4 dargestellt, dienen. Beide Kammern sind durch eine Membran 16 voneinander abgedichtet. Die äußere umlaufende Wulst der Membran dient hierbei als formschlüssiges Dichtelement. Beide Kammern sind in diesem Ausführungsbeispiel über eine Verschraubung (30) miteinander verbunden. An die Membran 16 ist einseitig eine elektrisch leitende, zentrisch gelochte Scheibe 15 durch eine Schnappverbindung angebaut. Die Membran mit der angebauten Scheibe ist in Richtung der Kammer B 19 positioniert. Die Kammer B 19 aus nicht elektrisch leitendem Material, Thread 27 and a sealing element 26, as shown in Fig. 4, serve. Both chambers are sealed by a membrane 16 from each other. The outer circumferential bead of the membrane serves as a positive sealing element. Both chambers are connected to each other in this embodiment via a screw (30). On the membrane 16, an electrically conductive, centrally perforated disc 15 is attached on one side by a snap connection. The diaphragm with the attached disc is positioned in the direction of the chamber B 19. The chamber B 19 made of non-electrically conductive material,
vorzugsweise Kunststoff bestehend, nimmt zwei voneinander isolierte preferably plastic, takes two isolated from each other
Kontaktelemente 10 auf. Diese Kontaktelemente 10 sind durch Schlitze in der Kammer B 19 in das Innere eingefügt und durch elektrisch leitende Befestigungen 10a positioniert und in geeigneter Weise fest verbunden, in diesem Beispiel durch Umformen der Befestigungen.

The invention shown in Fig. 2
Einrichtung zeigt die Offenstellung, das heißt die Membran befindet sich, weil kein Brennerdruck anliegt, am unteren Anschlag 21. Der Stromkreis 20 ist offen, es erfolgt keine Statusanzeige. Liegt durch öffnen des Hauptventils im Gasregelgerät Druck am Gasbrenner 2 an, wird der Druck durch die Öffnung 18 in das Innere der erfindungsgemäßen Einrichtung 1 auf die untere Seite der Membran 16 Device shows the open position, that is, the membrane is because no burner pressure is applied to the lower stop 21. The circuit 20 is open, there is no status display. If pressure is applied to the gas burner 2 by opening the main valve in the gas regulating device, the pressure through the opening 18 into the interior of the device 1 according to the invention is applied to the lower side of the membrane 16
übertragen. Von Vorteil ist dabei, dass die Größe der Öffnung 18 so bemessen ist, das bei Zerstörung der Membran 16 im Havariefall keine zündfähige, unzulässig hohe Gasmenge austreten kann. Weiterhin ermöglicht diese Auslegung, dass die Kammer B 19 kostengünstig aus Kunststoff gefertigt werden kann. Unter dem anliegenden Druck bewegt sich die Membran 16 bis zum oberen Anschlag, der durch beide elektrisch leitenden Befestigungen 10a gebildet wird. Die Endlage der Membran 16 unter anliegendem Druck wird in Fig.3 dargestellt. Mit dem Erreichen der Endlage der Membran 16 werden durch die Scheibe 15 beide Befestigungen 10a elektrisch verbunden, der Stromkreis 20 ist geschlossen und die transfer. The advantage here is that the size of the opening 18 is sized so that no destructive, impermissibly high amount of gas can escape in case of destruction of the membrane 16 in the event of an accident. Furthermore, this design allows the chamber B 19 can be inexpensively made of plastic. Under the applied pressure, the membrane 16 moves to the upper stop, which is formed by both electrically conductive fasteners 10 a. The end position of the membrane 16 under applied pressure is shown in Fig.3. With the achievement of the end position of the diaphragm 16 are both attachments 10 a electrically connected through the disc 15, the circuit 20 is closed and the

Die in Fig. 1 dargestellte zweite, erfindungsgemäße Einrichtung 1a, im Detail als Schnitt in Fig. 5 dargestellt, weist eine baulich modifizierte Kammer A 17b auf. Diese Kammer A weist zum Einbau in eine Zuführungsleitung, in diesem Beispiel die Zuführungsleitung 13 zum Zündbrenner 3, zwei Verbindungstellen als Eingang 22 und Ausgang 23 auf, hier vorzugsweise ausgelegt als metallisch dichtende Doppelkegelringverschraubung. Der Aufbau und die Funktionsweise der The illustrated in Fig. 1 second, inventive device 1a, shown in detail as a section in Fig. 5, has a structurally modified chamber A 17b. This chamber A has for installation in a supply line, in this example, the supply line 13 to the pilot burner 3, two connection points as input 22 and output 23, here preferably designed as a metallic sealing Doppelkegelringverschraubung. The structure and functioning of the
Statusanzeige entspricht auch bei diesem Beispiel der erfindungsgemäßen Status display also corresponds to the invention in this example
Einrichtung 1. Device 1.
Im Unterschied dazu erfolgt hier die Statusanzeige über eine zweite LED 12a in Abhängigkeit des Drucks am Zündgasbrenner 3. Mit Betätigung der Inbetriebnahme 24 des Gasregelgerätes 4 wird ein nicht dargestelltes Zündsicherungsventil geöffnet, Zündgas zum Zündbrenner freigegeben und gezündet. Da die Einrichtung 1a direkt in die Zuführungsleitung 13 eingebaut ist führt hier der Druck am Zündbrenner zur Hubbewegung der Membran 16. Das Schließen des Stromkreises 20 über die Befestigungen 10a und In contrast to this, the status is displayed here via a second LED 12a as a function of the pressure at the ignition gas burner 3. With actuation of the Commissioning 24 of the gas control unit 4, an unillustrated Zündsicherungsventil is opened, released ignition gas to the pilot burner and ignited. Since the device 1a is installed directly in the supply line 13 leads here the pressure at the pilot burner for lifting movement of the membrane 16. The closing of the circuit 20 via the fasteners 10a and
Kontaktelemente 10 erfolgt in gleicher weise wie im vorangegangenen Beispiel. Wird das Gasregelgerät außer Betrieb gesetzt geht der Zündgasdruck auf null. Die Membran 16 bewegt sich bis zum unteren Anschlag 21 zurück, der Stromkreis 20 wird geöffnet und die Statusanzeige, LED 12a, verlischt. Contact elements 10 takes place in the same way as in the previous example. If the gas control unit is put out of operation, the ignition gas pressure goes to zero. The membrane 16 moves back to the lower stop 21, the circuit 20 is opened and the status indicator, LED 12a, goes out.
Steht für die erfindungsgemäße Einrichtung 1 kein direkter Anschluss an einen Gasausgang der Gasregeleinrichtung 4 zur Verfügung kann wie in Fig. 6 gezeigt über eine modifizierte Kammer A 17c ein Fitting angebaut werden, der den direkten Einbau in die Zuführungsleitung zum Gasbrenner erlaubt. In diesem Beispiel werden als Eingang 22 und Ausgang 23 im Gewinde dichtende If there is no direct connection to a gas outlet of the gas control device 4 for the device 1 according to the invention, as shown in FIG. 6, a fitting can be installed via a modified chamber A 17c which permits direct installation in the supply line to the gas burner. In this example, as input 22 and output 23 in the thread sealing
Verschraubungen verwendet. Mit dieser Ausführung kann die erfindungsgemäße Einrichtung 1 universell als Statusanzeige für einen Gasbrenner genutzt werden und / oder nachträglich in vorhandene Gasgeräte eingebaut werden. Used glands. With this embodiment, the device 1 according to the invention can be used universally as a status indicator for a gas burner and / or be retrofitted in existing gas appliances.
Die erfindungsgemäße Einrichtung ist selbstredend nicht auf die dargestellten Ausführungsbeispiele beschränkt. Vielmehr sind Änderungen, Abwandlungen und Kombinationen möglich, ohne den Rahmen der Erfindung zu verlassen. The device according to the invention is of course not limited to the illustrated embodiments. Rather, changes, modifications and combinations are possible without departing from the scope of the invention.
So lässt sich ein erweiterter Anwendungsbereich erschließen, wenn anstelle des vorher beschriebenen Stromkreises zur Statusanzeige ein Relais angeschlossen wird. Über dieses Relais können in Abhängigkeit vom herrschenden Druck am Brenner Komponenten, wie zum Beispiel ein Gebläse, ein- und ausgeschaltet werden. Aufstellung der Bezuaszeichen This opens up a wider field of application if a relay is connected instead of the status display circuit described above. Depending on the prevailing pressure on the burner, components such as a blower can be switched on and off via this relay. Set up the Bezuaszeichen
