Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Armatur für einen Durchlauf-Wassererhitzer nach dem Oberbegriff des ersten Patentanspruches.The invention relates to a fitting for a continuous water heater according to the preamble of the first claim.

Stand der TechnikState of the art

Derartige Armaturen für Durchlauf-Wassererhitzer gibt es in den verschiedensten Ausführungen. Sie dienen zur Steuerung des Gasdurchflusses zu einem Brenner eines Wärmetauschers in Abhängigkeit vom Wasserdurchlauf.Such fittings for continuous flow water heaters are available in various designs. They serve to control the gas flow to a burner of a heat exchanger depending on the water flow.

So ist in der deutschen Offenlegungsschrift DE 198 25 046 A1 eine Gasarmatur für einen brennerbeheizten Wasserheizer beschrieben, die zuströmseitig ein Hauptgasventil aufweist, das mit einem Durchflussmesser verbunden ist. Dem Hauptgasventil ist ein Wassermangelventil nachgeschaltet, das mit dem Durchflussmesser verbunden ist. Dem Wassermangelventil ist wiederum ein mit einer Auswerteschaltung verbundenes thermostatisch gesteuertes Ventil nachgeschaltet. Beim Betrieb des Wasserheizers kann mittels zweier Bedienelemente einerseits der Wasserdurchsatz und andererseits die Temperatur des abströmenden Warmwassers eingestellt werden.Such is in the German Offenlegungsschrift DE 198 25 046 A1 a gas fitting for a burner-heated water heater described on the upstream side has a main gas valve which is connected to a flow meter. The main gas valve is followed by a water shortage valve, which is connected to the flow meter. The water shortage valve is in turn connected downstream of a thermostatically controlled valve connected to an evaluation circuit. During operation of the water heater can be adjusted by means of two controls on the one hand, the water flow rate and on the other hand, the temperature of the outflowing hot water.

Aus der EP 1 170 549 A2 ist ein gasbeheizter Durchlauferhitzer mit einem von einem Brenner beheizten Wärmetauscher bekannt, dem ein Wasserventil in einem Wasserschalter vorgeschaltet ist und dem gasseitig Gasventile vorgeschaltet sind, von denen eines vom Wasserschalter und ein anderes von einem gasdruckgesteuerten Servoventil gesteuert ist. Während über eine erste Handhabe ein dem vom Servoventil vorgeschaltetem Gasventil nachgeschaltetes Justierventil betätigt wird, kann über eine zweite Handhabe das Wasserventil betätigt werden.From the EP 1 170 549 A2 is a gas-fired water heater with a burner heated by a heat exchanger known, which is preceded by a water valve in a water switch and the gas side gas valves are connected upstream, one of which is controlled by the water switch and another of a gas pressure controlled servo valve. While a downstream of the servo valve upstream gas adjustment valve is actuated via a first handle, the water valve can be actuated via a second handle.

Einen ähnlichen Aufbau weist ein in der Offenlegungsschrift DE 100 30 118 A1 beschriebener gasbeheizter Durchlaufwassererhitzer auf. Auch hier sind zwei Handhaben vorhanden, über welche die Bedienung des Durchlaufwassererhitzers erfolgt.A similar structure has a in the published patent application DE 100 30 118 A1 described gas-fired continuous water heater on. Again, there are two handles, via which the operation of the continuous flow water heater takes place.

Auch in der österreichischen Patentschrift AT 406 611 B wird ein Wasserheizer gezeigt, der zwei Bedienelemente, in dieser Ausführung ein Bedienknopf und ein Zündknopf, aufweist.Also in the Austrian patent AT 406 611 B a water heater is shown, the two controls, in this embodiment, a control knob and a firing button has.

Bei allen diesen Armaturen ist es von Nachteil, dass für die Ein-/Ausschaltung des Durchlauf-Wassererhitzers oder die Einstellung der gewünschten Betriebsparameter, wie Wassertemperatur und Wassermenge zwei separate Bedienelemente benötigt werden, für die entsprechende Durchbrüche in der Außenwand der Armatur vorhanden und damit selbstredend auch abgedichtet werden müssen. Desweiteren ist dadurch der Aufbau aufwendiger und die Bedienung durch den Anwender umständlicher.In all these fittings, it is disadvantageous that for the on / off of the continuous water heater or the setting of the desired operating parameters, such as water temperature and water volume two separate controls are needed for the corresponding openings in the outer wall of the valve available and thus of course also have to be sealed. Furthermore, this makes the structure more complex and the operation by the user cumbersome.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt das Problem zugrunde bei einer Armatur für einen Durchlauf-Wassererhitzer nach dem Oberbegriff des ersten Patentanspruches eine einfache und übersichtlichere manuelle Bedienung zu gewährleisten, indem nur ein Bedienelement betätigt werden muss. Auf Grund der Verringerung der Durchbrüche durch die Gehäusewandung der Armatur wird gleichzeitig die Gefahr des Auftretens von Undichtigkeiten herabgesetzt. Weiterhin soll der Herstellungsaufwand minimiert werden.The invention is based on the problem in a fitting for a continuous flow water heater according to the preamble of the first claim to ensure a simple and clearer manual operation by only one control element must be pressed. Due to the reduction in the openings through the housing wall of the valve at the same time the risk of the occurrence of leaks is reduced. Furthermore, the production cost should be minimized.

Erfindungsgemäß wird das Problem dadurch gelöst, dass auf der aus dem wasserführenden Gehäuse herausragenden Spindel zusätzlich zum Bedienelement ein Schaltelement drehbar gelagert ist, wobei eine Drehbewegung des Bedienelements über Mitnehmer auf das Schaltelement übertragbar ist. Dieses Schaltelement weist desweiteren eine Schaltkontur auf, über die ein fest angeordneter Mikroschalter betätigbar ist. Über diesen Mikroschalter ist eine elektronische Zünd- und Überwachungseinrichtung elektrisch ansteuerbar, über die mittels eines elektrisch ansteuerbaren Ventils der Gaszufluss zum Brenner absperrbar ist.According to the invention the problem is solved in that in addition to the operating element, a switching element is rotatably mounted on the protruding from the water-bearing spindle spindle, wherein a rotational movement of the control element via driver on the switching element is transferable. This switching element furthermore has a switching contour, via which a permanently arranged microswitch can be actuated. About this microswitch an electronic ignition and monitoring device is electrically controlled, via which by means of an electrically controllable valve, the gas flow to the burner can be shut off.

Damit wurde eine Lösung gefunden, mit der die weiter oben genannten Nachteile des Standes der Technik beseitigt wurden. Durch die manuelle Betätigung nur eines einzigen Bedienelementes ist eine manuelle Außer- / Inbetriebnahme des Durchlauf- Wassererhitzers sowie eine Einstellung des Wasserdurchflusses auf einen vorgegebenen Wert entsprechend den Versorgungsbedingungen bzw. eines manuellen Ausgleiches der Schwankungen der Kaltwassertemperatur möglich.Thus, a solution was found with which the above-mentioned disadvantages of the prior art have been eliminated. By manually operating only a single control element, a manual decommissioning / commissioning of the continuous flow water heater and an adjustment of the water flow to a predetermined value according to the supply conditions or a manual compensation for the fluctuations of the cold water temperature is possible.

Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments of the invention will become apparent from the dependent claims.

Um den Herstellungsaufwand noch weiter zu verringern erweist es sich als günstige Ausgestaltung der Armatur, wenn das zum Absperren des Gaszuflusses über das Bedienelement dienende Ventil durch das zur elektronischen Zünd- und Überwachungseinrichtung zugehörige Servoventil gebildet wird.In order to reduce the production cost even further, it proves to be a favorable embodiment of the valve when the serving to shut off the gas flow via the control valve is formed by the electronic ignition and monitoring device associated servo valve.

Eine einfache und sichere Möglichkeit, um die Drehbewegung des Bedienelements auf das Schaltelement zu übertragen lässt sich dadurch realisieren, dass der Mitnehmer durch ein oder mehrere am Bedienelement befindliche Rippen gebildet wird, die in am Schaltelement befindliche Schlitze hineinragen.A simple and secure way to transmit the rotational movement of the operating element to the switching element can be realized in that the driver is formed by one or more controls located on the ribs, which protrude into slots located on the switching element.

Um eine sichere Fixierung von Bedienelement und Schaltelement in Längsrichtung zu gewährleisten ist es vorteilhaft, wenn das Schaltelement über Rasthaken mit dem Bedienelement verbunden ist.In order to ensure a secure fixation of the control element and switching element in the longitudinal direction, it is advantageous if the switching element is connected via latching hooks with the operating element.

Die in den Figuren dargestellte beispielhafte erfindungsgemäße Armatur für einen Durchlauf-Wassererhitzer dient zur Steuerung des Gasdurchflusses zu einem Brenner eines nicht dargestellten Wärmetauschers in Abhängigkeit vom Wasserdurchlauf. Der Brenner besteht in diesem Ausführungsbeispiel aus einem nicht dargestellten Zündbrenner und einem ebenfalls nicht dargestellten Hauptbrenner. Die Armatur besteht aus:

  • einem den Wasserdurchlauf zum Wärmetauscher steuernden Wasserteil 1,
  • einem den Gasdurchlauf zum Brenner in Abhängigkeit vom Wasserdurchlauf steuernden Gasteil 2,
  • einer elektronischen Zünd- und Überwachungseinrichtung 3.
The exemplary fitting according to the invention for a continuous flow water heater shown in the figures serves to control the gas flow to a burner of a heat exchanger, not shown, depending on the water flow. The burner consists in this embodiment of a pilot burner, not shown, and a main burner, also not shown. The fitting consists of:
  • a water passage 1 controlling the water passage to the heat exchanger;
  • a gas passage 2 to the burner as a function of the water passage controlling
  • an electronic ignition and monitoring device 3.

Im Gasteil 2 sind neben anderen, dem Fachmann bekannten und daher hier nicht weiter erläuterten Bauteilen ein Stellventil und ein Hauptventil untergebracht. Das Hauptventil wird über eine dem Fachmann ebenfalls bekannte elektronische Zünd- und Überwachungseinrichtung 3, auch als sogenannter Feuerungsautomat bekannt, angesteuert, die mit dem Gasteil 2 verbunden ist.In the gas part 2, a control valve and a main valve are housed among other, known in the art and therefore not further explained components. The main valve is controlled by a well-known to those skilled electronic ignition and monitoring device 3, also known as a so-called automatic burner, which is connected to the gas part 2.

Das Stellventil wird über eine Übertragung 4 angesteuert, die die vom Wasserdurchlauf abhängige Bewegung einer im Wasserteil 1 befindlichen Wassermembran aus dem Innenraum des wasserführenden Gehäuses 5 an die Außenseite und sodann von dort in das gasführende Gehäuse 6 des Gasteiles 2 zum Stellventil überträgt.The control valve is controlled via a transmission 4, which transmits the water flow-dependent movement of a water in the water part 1 water membrane from the interior of the water-bearing housing 5 to the outside and then from there into the gas-carrying housing 6 of the gas part 2 to the control valve.

Im wasserführenden Gehäuse 6 befinden sich weiterhin, neben anderen dem Fachmann bekannten und daher ebenfalls nicht weiter erläuterten Bauteilen, eine Venturidüse und ein Voreinstellglied, das die Einstellung des Wasserdurchflusses auf einen vorgegebenen Wert entsprechend den Versorgungsbedingungen erlaubt. Dieses Voreinstellglied dient gleichzeitig als Temperaturkorrektor, d.h. es ermöglicht den manuellen Ausgleich der Schwankungen der Kaltwassertemperatur.In the water-bearing housing 6 are further, among other known in the art and therefore also not further explained components, a venturi and a presetting, which allows the adjustment of the water flow to a predetermined value according to the supply conditions. This presetting member also serves as a temperature corrector, i. It allows the manual compensation of fluctuations in the chilled water temperature.

Zur Ermöglichung der manuellen Betätigung ragt eine mit dem Voreinstellglied verbundene Spindel 7 aus dem wasserführenden Gehäuse 5 heraus, auf der ein Bedienelement 8 befestigt ist. Zusätzlich zum Bedienelement 8 ist auf der aus dem wasserführenden Gehäuse 5 herausragenden Spindel 7 ein Schaltelement 9 drehbar gelagert, wobei eine Drehbewegung des Bedienelements 8 über einen Mitnehmer auf das Schaltelement 9 übertragbar ist.To enable the manual operation, a spindle 7 connected to the presetting member projects out of the water-bearing housing 5, on which a control element 8 is mounted. In addition to the operating element 8, a switching element 9 is rotatably mounted on the protruding from the water-bearing housing 5 spindle 7, wherein a rotational movement of the control element 8 via a driver on the switching element 9 is transferable.

Der Mitnehmer wird in diesem Ausführungsbeispiel in günstiger Weise durch mehrere am Bedienelement 8 befindliche axiale Rippen 10 gebildet, die in ihnen zugeordnete am Schaltelement 9 befindliche axiale Schlitze 11 hineinragen. Um auch eine Lagefixierung des Schaltelements 9 in Längsrichtung der Spindel 7 zu gewährleisten, weisen Bedienelement 8 und Schaltelement 9 einander zugewandte Rasthaken 12 auf, die eine zuverlässige Verbindung gewährleisten.The driver is formed in this embodiment in a favorable manner by a plurality of the control element 8 located axial ribs 10 which project in them associated with the switching element 9 axial slots 11 protrude. In order to ensure a positional fixation of the switching element 9 in the longitudinal direction of the spindle 7, have control element 8 and switching element 9 facing latching hooks 12, which ensure a reliable connection.

Das Schaltelement 9 besitzt desweiteren eine Schaltkontur 13, über die ein in diesem Ausführungsbeispiel am gasführenden Gehäuse 6 fest angeordneter Mikroschalter 14 betätigbar ist. Der Mikroschalter 14 ist elektrisch mit der elektronischen Zünd- und Überwachungseinrichtung 3 verbunden.The switching element 9 further has a switching contour 13, via which a fixedly arranged in this embodiment, the gas-conducting housing 6 microswitch 14 can be actuated. The microswitch 14 is electrically connected to the electronic ignition and monitoring device 3.

Die Wirkungsweise der in den Figuren dargestellten Armatur für einen Durchlauf-Wassererhitzer ist wie folgt:The operation of the valve shown in the figures for a continuous flow water heater is as follows:

In den Figuren 1 und 2 ist eine Ausführung einer erfindungsgemäßen Armatur für einen Durchlauf-Wassererhitzer im ausgeschalteten Zustand gezeigt. Das Bedienelement 8 befindet sich in der Aus-Stellung. Dabei ist das Schaltelement 9 so weit gedreht, dass die Schaltkontur 13 den Taster 15 des Mikroschalters 14 freigegeben hat. Über die elektronische Zünd- und Überwachungseinrichtung 3 wird dadurch die Gaszufuhr zum Brenner abgesperrt und unabhängig von einer Wasserentnahme an einer dem Durchlauf-Wassererhitzer nachgeordneten Wasserzapfstelle bleibt dieser im ausgeschalteten Zustand.In the FIGS. 1 and 2 an embodiment of a valve according to the invention for a continuous flow water heater is shown in the off state. The operating element 8 is in the off position. In this case, the switching element 9 is rotated so far that the switching contour 13 has released the button 15 of the microswitch 14. Through the electronic ignition and monitoring device 3, the gas supply to the burner is thereby shut off and regardless of a water removal at a water heater downstream of the water tap this remains in the off state.

Um die Armatur einzuschalten muss das Bedienungselement 8 so weit gedreht werden, dass es sich im möglichen Stellbereich zur Verstellung des Wasserdurchflusses bzw. des manuellen Ausgleichs der Schwankungen der Kaltwassertemperatur befindet, so wie es beispielsweise in den Figuren 3 und 4 dargestellt ist.To turn on the valve, the control element 8 must be turned so far that it is in the possible adjustment range for adjusting the water flow or the manual compensation of the fluctuations of the cold water temperature, as it is for example in the Figures 3 and 4 is shown.

Sobald dann an einer nachgeordneten Zapfstelle eine Wasserentnahme erfolgt wird über die elektronische Zünd- und Überwachungseinrichtung 3 die Gaszufuhr zum Brenner des Wärmetauschers geöffnet und das Gas gezündet. Der Brenner bleibt in Betrieb, bis keine Wasserentnahme mehr erfolgt. Der Durchlauf-Wassererhitzer bleibt jedoch betriebsbereit und kann durch eine erneute Wasserentnahme wieder in Betrieb genommen werden.As soon as a water tap is then taken at a downstream tapping point, the gas supply to the burner of the heat exchanger is opened via the electronic ignition and monitoring device 3 and the gas is ignited. The burner remains in operation until no water is removed. However, the continuous water heater remains operational and can be put back into operation by renewed removal of water.

Um den Durchlauf-Wassererhitzer manuell auszuschalten wird das Bedienelement über den zur Einstellung des Wasserdurchflusses möglichen Stellbereich hinaus in die Aus-Stellung bewegt; wie in den Figuren 1 und 2 gezeigt. Wie bereits weiter oben erläutert, wird dadurch die Gaszufuhr zum Brenner unabhängig von einer auftretenden Wasserentnahme abgesperrt.In order to switch off the continuous water heater manually, the operating element is moved beyond the setting range possible for setting the water flow to the off position; like in the FIGS. 1 and 2 shown. As already explained above, thereby the gas supply to the burner is shut off regardless of an occurring water withdrawal.

Die erfindungsgemäße Armatur für einen Durchlauf-Wassererhitzer ist selbstredend nicht auf das dargestellte Ausführungsbeispiel beschränkt.The fitting according to the invention for a continuous flow water heater is of course not limited to the illustrated embodiment.

So kann es sich beispielsweise als günstig erweisen, wenn die Aus-Stellung erst durch Überwindung einer das Ende des Einstellbereiches signalisierenden, aber überdrehbaren Rastung erreicht wird, um bei einer gewünschten Verstellung des Wasserdurchflusses bzw. eines manuellen Ausgleiches der Schwankungen der Kaltwassertemperatur nicht versehentlich die Aus-Stellung einzustellen.For example, it may prove to be advantageous if the off position is reached only by overcoming a the end of the adjustment range signaling, but überdrehbaren detent to accidentally at a desired adjustment of the water flow or a manual compensation for the fluctuations of the cold water temperature off Position.
