Description

Die Erfindung betrifft eine Sanitärarmatur zur Temperatur- und/oder Mengeneinstellung von Mischwasser und zur Mengeneinstellung von Heißwassser.The invention relates to a sanitary fitting for setting the temperature and / or amount of mixed water and for setting the amount of hot water.

In einer Sanitärarmatur kann zur Temperatur- und/oder Mengeneinstellung von Mischwasser eine Mischbatterie, insbesondere eine Einhebel-Mischbatterie, eingebaut sein, mit deren Betätigungshebel die Temperatur und/oder die Menge des Mischwassers einstellbar ist. Hierzu ist die Mischbatterie eingangsseitig mit einer an das Wasserversorgungsnetz angeschlossenen Kaltwasserleitung sowie einer Warmwasserleitung verbunden. Ausgangsseitig ist die Mischbatterie über eine Mischwasserleitung zum Wasserauslauf der Sanitärarmatur geführt.A mixer tap, in particular a single-lever mixer tap, can be installed in a sanitary fitting to adjust the temperature and / or quantity of mixed water, with the actuating lever of which the temperature and / or the quantity of the mixed water can be adjusted. For this purpose, the mixer tap is connected on the input side to a cold water pipe connected to the water supply network and a hot water pipe. On the output side, the mixer tap is led to the water outlet of the sanitary fitting via a mixed water pipe.

Zur Erhöhung der Funktionalität kann eine gattungsgemäße Sanitärarmatur zusätzlich zum Mischwasser kochend heißes Wasser bereitstellen, das von einem Boiler über eine separate Heißwasser-Leitung zum Wasserauslauf der Sanitärarmatur geführt ist. Zur Mengeneinstellung des Heißwassers weist die Sanitärarmatur ein manuell bedienbares, zweites Betätigungselement auf, etwa einen an der Sanitärarmatur drehgelagerten Bedienknebel. Dieser ist vom Nutzer in eine Heißwasser-Position drehbetätigbar, um den Strömungsweg des Heißwassers zum Wasserauslauf der Sanitärarmatur freizugeben. Hierzu ist in der Sanitärarmatur ein Sperrventil eingebaut, das mit dem zweiten Betätigungselement mechanisch geöffnet und/oder geschlossen werden kann.To increase the functionality, a generic sanitary fitting can provide boiling hot water in addition to the mixed water, which is led from a boiler via a separate hot water line to the water outlet of the sanitary fitting. To adjust the amount of hot water, the sanitary fitting has a manually operable, second actuating element, for example an operating knob rotatably mounted on the sanitary fitting. This can be rotated by the user into a hot water position in order to release the flow path of the hot water to the water outlet of the sanitary fitting. For this purpose, a shut-off valve is installed in the sanitary fitting, which can be opened and / or closed mechanically with the second actuating element.

Zur weiteren Steigerung der Funktionalität kann über die Sanitärarmatur Wasser abgezapft werden, das in einer Kühler-, Karbonator- und/oder Filtereinheit vorbehandelt worden ist.To further increase functionality, water that has been pretreated in a cooler, carbonator and / or filter unit can be tapped off via the sanitary fitting.

Derartige Sanitärarmaturen sind beispielsweise in der WO 2009/035319 A1 , der WO 94/20784 A1 , der DE 10 2008 006255 A1 oder der EP 2 472 150 A1 beschrieben.Such sanitary fittings are for example in the WO 2009/035319 A1 , of the WO 94/20784 A1 , of the DE 10 2008 006255 A1 or the EP 2 472 150 A1 described.

Aus der EP 2 672 027 A1 , die jedoch nach dem Prioritätstag der vorliegenden Anmeldung veröffentlicht wurde, ist ebenfalls eine solche Sanitärarmatur bekannt.From the EP 2 672 027 A1 However, which was published after the priority date of the present application, such a sanitary fitting is also known.

Die oben erwähnten Zusatzfunktionen der Sanitärarmatur sind mit einem erhöhten Bauraumaufwand in der Sanitärarmatur verbunden. Die Sanitärarmatur ist daher entsprechend groß zu dimensionieren, was einer gegebenenfalls kompakteren Gestaltung der Sanitärarmatur entgegensteht.The above-mentioned additional functions of the sanitary fitting are associated with an increased amount of installation space in the sanitary fitting. The sanitary fitting is therefore to be dimensioned correspondingly large, which opposes a possibly more compact design of the sanitary fitting.

Die Aufgabe der Erfindung besteht darin, eine Sanitärarmatur bereitzustellen, bei der die Sanitärarmatur trotz erhöhter Funktionalität kompakt gestaltet ist.The object of the invention is to provide a sanitary fitting in which the sanitary fitting is designed to be compact despite increased functionality.

Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen offenbart.The object is achieved by the features of claim 1. Preferred developments of the invention are disclosed in the dependent claims.

Die Erfindung beruht auf dem Sachverhalt, dass die Bereitstellung von Heißwasser und/oder die Bereitstellung von Mischwasser mechanisch durch eine Mischbatterie und/oder einem Heißwasser-Sperrventil erfolgt, die manuell vom Nutzer bedienbar sind sowie unmittelbar in der Sanitärarmatur eingebaut sind. Die Sanitärarmatur muss daher einen entsprechend groß bemessenen Bauraum für die Mischbatterie und für das Sperrventil vorsehen. Vor diesem Hintergrund erfolgt erfindungsgemäß die Mengeneinstellung von Heißwasser nicht mehr über ein manuell bedienbares Sperrventil, sondern vielmehr durch ein Ventilelement, insbesondere ein Magnetventil, das vom zweiten Betätigungselement elektrisch ansteuerbar ist.The invention is based on the fact that the provision of hot water and / or the provision of mixed water takes place mechanically by a mixer tap and / or a hot water shut-off valve, which can be operated manually by the user and are installed directly in the sanitary fitting. The sanitary fitting must therefore be dimensioned accordingly large Provide space for the mixer tap and for the shut-off valve. Against this background, according to the invention, the amount of hot water is no longer adjusted via a manually operated shut-off valve, but rather via a valve element, in particular a solenoid valve, which can be electrically controlled by the second actuating element.

Dabei ist dem zweiten Betätigungselement ein Sensorelement zugeordnet, das zum Beispiel die Position des Betätigungselementes elektrisch erfassen kann. Das Sensorelement ist über eine Signalleitung mit dem Heißwasser-Ventilelement signaltechnisch verbunden. Bei einer Stellbewegung des zweiten Betätigungselementes generiert das Sensorelement ein Stellsignal, mit dem das Heißwasser-Ventilelement ansteuerbar ist. Das zweite Betätigungselement kann zwischen einer Ruheposition, in der das Heißwasser-Ventilelement geschlossen ist, und einer Heißwasser-Position gedreht werden. In der Heißwasser-Position ist das Heißwasser-Ventilelement geöffnet.A sensor element is assigned to the second actuating element, which can, for example, electrically detect the position of the actuating element. The sensor element is signal-connected to the hot water valve element via a signal line. When the second actuating element is actuated, the sensor element generates an actuating signal with which the hot water valve element can be controlled. The second actuating element can be rotated between a rest position in which the hot water valve element is closed and a hot water position. In the hot water position, the hot water valve element is open.

Zur Vermeidung von Fehlbedienungen sowie zum Schutz vor Verletzungen sind zusätzliche Sicherheitsmaßnahmen, die eine unbeabsichtigte Betätigung des Heißwasser-Ventilelementes vermeiden, von Vorteil. Dazu wird das zweite Betätigungselement unter Aufbau einer Rückstellkraft von der Ruheposition in die Heißwasser-Position manuell gedreht. Beim Loslassen wird daher das zweite Betätigungselement selbsttätig wieder in seine Ruheposition zurückgestellt.To avoid incorrect operation and to protect against injuries, additional safety measures that prevent unintentional actuation of the hot water valve element are advantageous. For this purpose, the second actuating element is manually rotated from the rest position to the hot water position while building up a restoring force. At the If you let go, the second actuating element is therefore automatically returned to its rest position.

Das zweite Betätigungselement ist nach wie vor an der Sanitärarmatur angeordnet, wohingegen das elektrisch ansteuerbare Heißwasser-Ventilelernerit gegebenenfalls davon beabstandet, das heißt zum Beispiel auch außerhalb der Sanitärarmatur angeordnet sein kann. Beispielhaft kann das Ventilelement in der Strömungsrichtung stromauf der Sanitärarmatur in einer Heißwasser-Leitung angeordnet sein.The second actuating element is still arranged on the sanitary fitting, whereas the electrically controllable hot water valve element may optionally be at a distance from it, that is to say, for example, can also be arranged outside the sanitary fitting. For example, the valve element can be arranged in the flow direction upstream of the sanitary fitting in a hot water line.

Alternativ und/oder zusätzlich dazu kann dem zweiten Betätigungselement ein Sicherungselement zugeordnet sein, etwa ein im zweiten Betätigungselement verstellbar angeordneter Schieber. Bevorzugt kann die Stellbewegung des zweiten Betätigungselementes erst nach erfolgter Betätigung des Sicherungselementes freigegeben werden.Alternatively and / or in addition to this, a securing element can be assigned to the second actuating element, for example a slide which is adjustably arranged in the second actuating element. The adjusting movement of the second actuating element can preferably only be released after the securing element has been actuated.

Als weitere Sicherungsmaßnahme kann dem Heißwasser-Ventilelement ein Zeitglied zugeordnet sein. Mit Hilfe des Zeitgliedes kann nach Ablauf einer zum Beispiel werksseitig oder benutzerseitig vorgebbaren Zeitdauer das vom zweiten Betätigungselement geöffnete Heißwasser-Ventilelement selbsttätig wieder geschlossen werden. Nach Ablauf dieser Zeitdauer wird daher die Heißwasser-Leitung unterbrochen, und zwar auch dann, wenn das zweite Betätigungselement noch in seiner Heißwasser-Position ist.A timer can be assigned to the hot water valve element as a further safety measure. With the aid of the timer, the hot water valve element opened by the second actuating element can be automatically closed again after a period of time that can be preset at the factory or by the user, for example. After this period of time has elapsed, the hot water line is therefore interrupted, even if the second actuating element is still in its hot water position.

Zur weiteren Steigerung der Funktionalität kann der Sanitärarmatur eine Kühler-, Karbonator- und/oder Filtereinheit zugeordnet sein. Diese Einheit kann über eine separate Zuleitung in Strömungsverbindung mit der Sanitärarmatur sein. Damit das von der Einheit durch Filtrierung, Karbonisierung und/oder Kühlung vorbehandelte Wasser abgezapft werden kann, ist bevorzugt das zweite Betätigungselement zu bedienen. Das zweite Betätigungselement kann über entsprechende Signalleitungen die Einheit bevorzugt elektronisch ansteuern. Auf diese Weise kann das zweite Betätigungselement in Doppelfunktion sowohl eine Heißwasser-Mengeneinstellung als auch die Einstellung des vorbehandelten Wassers ausführen.To further increase the functionality, the sanitary fitting can be assigned a cooler, carbonator and / or filter unit. This unit can be in flow connection with the sanitary fitting via a separate feed line. The second actuating element should preferably be operated so that the water that has been pretreated by filtration, carbonation and / or cooling can be tapped off by the unit. The second The actuating element can preferably control the unit electronically via corresponding signal lines. In this way, the second actuating element can perform both a hot water volume setting and the setting of the pretreated water in a dual function.

Vor diesem Hintergrund ist das zweite Betätigungselement nicht nur zwischen der Ruheposition und der Heißwasser-Position, sondern zusätzlich auch in zumindest eine weitere Stellposition verstellbar. Das zweite Betätigungselement kann in dieser Stellposition den Strömungsweg von der oben erwähnten Behandlungseinheit bis zum Wasserauslauf der Sanitärarmatur freigeben. Bevorzugt ist in einer ersten Stellposition des zweiten Betätigungselements speziell gekühltes sowie gefiltertes Wasser bereitstellbar, während in seinen weiteren Stellpositionen das gekühlte Wasser zusätzlich mit jeweils unterschiedlichem Kohlensäuregehalt abgezapft werden kann.Against this background, the second actuating element can be adjusted not only between the rest position and the hot water position, but also in at least one further setting position. In this setting position, the second actuating element can clear the flow path from the above-mentioned treatment unit to the water outlet of the sanitary fitting. In a first setting position of the second actuating element, specially cooled and filtered water can preferably be provided, while in its further setting positions the cooled water can additionally be tapped with a different carbonic acid content in each case.

Aus Sicherheitsgründen ist es von großer Bedeutung, ein unbeabsichtigtes Abzapfen von Heißwasser zu vermeiden. Von daher ist es von Vorteil, wenn die Stellbewegung des zweiten Betätigungselementes von der Ruheposition in die Heißwasser-Position und dessen Stellbewegung von der Ruheposition in die zumindest eine weitere Stellposition zueinander gegenläufig gestaltet sind. Das zweite Betätigungselement ist ein an der Sanitärarmatur drehgelagerter Bedienknebel, der in zueinander gegenläufigen Drehrichtungen jeweils in die Heißwasser-Position oder in die weitere Stellposition verdrehbar ist. Die oben erwähnten Sicherungsmaßnahmen gelten dabei bevorzugt lediglich für eine Stellbewegung des zweiten Betätigungselementes in die Heißwasser-Position, nicht jedoch für eine gegenläufige Stellbewegung in die weitere Stellposition.For safety reasons, it is very important to avoid unintentional tapping of hot water. It is therefore advantageous if the adjusting movement of the second actuating element from the rest position into the hot water position and its adjusting movement from the rest position into the at least one further adjusting position are designed in opposite directions to one another. The second actuating element is a control knob which is rotatably mounted on the sanitary fitting and which can be rotated in mutually opposite directions of rotation into the hot water position or into the further setting position. The above-mentioned safety measures preferably apply only to an adjusting movement of the second actuating element into the hot water position, but not to an opposing adjusting movement into the further adjusting position.

Wie oben erwähnt, ist das Heißwasser-Ventilelement nicht mechanisch einstellbar, sondern elektrisch ansteuerbar. Im Unterschied dazu kann die Temperatur- und/oder Mengeneinstellung des Mischwasser mechanisch über eine Mischbatterie, insbesondere eine Einhebel-Mischbatterie erfolgen, die in die Sanitärarmatur eingesetzt ist. In diesem Fall dient der Hebel der Mischbatterie als oben erwähntes erstes Betätigungselement und der vorgenannte Bedienknebel als zweites Betätigungselement. Die Mischbatterie kann bevorzugt eingangsseitig mit einer am Versorgungsnetz angeschlossenen Kaltwasserleitung sowie einer Warmwasserleitung verbunden sein. Ausgangsseitig kann die Mischbatterie mit einer zum Wasserauslauf der Sanitärarmatur geführten Mischwasserleitung verbunden sein.As mentioned above, the hot water valve element is not mechanically adjustable, but can be controlled electrically. In contrast to this, the temperature and / or quantity of the mixed water can be set mechanically via a mixer tap, in particular a single-lever mixer tap, which is inserted into the sanitary fitting. In this case, the lever of the mixer tap serves as the first operating element mentioned above and the aforementioned control knob as the second operating element. The mixer tap can preferably be connected on the input side to a cold water line connected to the supply network and to a hot water line. On the output side, the mixer tap can be connected to a mixed water line leading to the water outlet of the sanitary fitting.

Bevorzugt ist eingangsseitig am Wasserauslauf der Sanitärarmatur ein Anschlussstück vorgesehen, das eine erste Anschlussöffnung für die Heißwasser-Leitung, eine zweite Anschlussöffnung für die Mischwasser-Leitung und/oder eine dritte Anschlussöffnung für die Zuleitung von der Kühler-, Karbonator- und/oder Filtereinheit aufweist.A connection piece is preferably provided on the inlet side at the water outlet of the sanitary fitting which has a first connection opening for the hot water line, a second connection opening for the mixed water line and / or a third connection opening for the supply line from the cooler, carbonator and / or filter unit .

Die Erfindung und ihre vorteilhaften Aus- und Weiterbildungen sowie deren Vorteile sind nachfolgend anhand von Zeichnungen näher erläutert.The invention and its advantageous designs and developments as well as their advantages are explained in more detail below with reference to drawings.

Das Anschlussstück 23 ist in der Fig. 1 in einem vertikal nach oben offenen Montagestutzen 19 des Armaturenkörpers 1 angedeutet, und zwar an der Eingangsseite des Wasserauslaufes 3.The mixed water line 15 connected to the mixer 9 is in a plug-in connection with a first reject opening 27 provided in a connection piece 23. The connection piece 23 is in the Fig. 1 indicated in a vertically upwardly open mounting socket 19 of the fitting body 1, specifically on the inlet side of the water outlet 3.

Zudem ist separat von der Mischwasserleitung 15 eine Heißwasser-Leitung 29 vorgesehen. Die Heißwasser-Leitung 29 ist in einer zweiten Anschlussöffnung 31 des Anschlussstückes 23 eingesteckt und bis zu einem unterhalb der Küchenarbeitsplatte vorgesehenen Boiler 33 geführt. Zusätzlich zum Boiler 33 ist eine Kühler-, Karbonator- und/oder Filtereinheit 34 vorgesehen, in der Frischwasser gefiltert, gekühlt und/oder mit Kohlensäure versetzt werden kann. Die Einheit 34 ist über eine Zuleitung 35 strömungstechnisch mit der Sanitärarmatur verbunden und mit seinem oberen Ende in Steckverbindung mit einer dritten Anschlussöffnung 37 des Anschlussstückes 23.In addition, a hot water line 29 is provided separately from the mixed water line 15. The hot water line 29 is inserted into a second connection opening 31 of the connection piece 23 and led to a boiler 33 provided below the kitchen worktop. In addition to the boiler 33, a cooler, carbonator and / or filter unit 34 is provided in which fresh water can be filtered, cooled and / or carbonated. The unit 34 is fluidically connected to the sanitary fitting via a feed line 35 and, at its upper end, is plugged into a third connection opening 37 of the connection piece 23.

Wie aus der Fig. 1 weiter hervorgeht, ist im Montagestutzen 25 ein Sensorelement 39 zur Drehwinkelerfassung des Bedienknebels 21 vorgesehen. Das Sensorelement 39 ist über eine Signalleitung 41 in Signalverbindung mit einem Elektromagnetventil 43. Das Elektromagnetventil 43 ist außerhalb der Sanitärarmatur, das heißt in der Strömungsrichtung mit Abstand vor der Sanitärarmatur angeordnet.As from the Fig. 1 It can also be seen that a sensor element 39 for detecting the angle of rotation of the control knob 21 is provided in the mounting socket 25. The sensor element 39 is in signal connection with an electromagnetic valve 43 via a signal line 41. The electromagnetic valve 43 is arranged outside the sanitary fitting, that is to say at a distance in front of the sanitary fitting in the direction of flow.

Zudem ist dem Elektromagnetventil 43 ein Zeitglied 45 signaltechnisch vorgeschaltet. Mit Hilfe des Zeitgliedes 45 kann nach Ablauf einer zum Beispiel werksseitig oder benutzerseitig vorgebbaren Zeitdauer Δt das mit dem Bedienknebel 21 geöffnete Elektromagnetventil 43 selbsttätig wieder geschlossen werden. Nach Ablauf dieser Zeitdauer Δt wird die Heißwasser-Leitung 29 geschlossen, und zwar auch dann, wenn der Bedienknebel 21 noch in seiner Heißwasser-Position H ist.In addition, a timing element 45 is connected upstream of the solenoid valve 43 for signaling purposes. With the aid of the timing element 45, after a period of time Δt which can be preset at the factory or by the user, for example, the solenoid valve 43 opened with the control knob 21 can be automatically closed again. After this period of time Δt has elapsed, the hot water line 29 is closed, even if the control knob 21 is still in its hot water position H.

Die Spannungsversorgung der oben genannten elektrischen Komponenten kann beispielhaft durch die Einheit 34 erfolgen. Das Sensorelement 39 ist über eine weitere Signalleitung 47 an der Einheit 34 angeschlossen. Die beiden Signalleitungen 41, 47 verlaufen in der Fig. 1 aus Gründen der Übersichtlichkeit außerhalb der Sanitärarmatur. In der tatsächlichen Einbausituation sind die Signalleitungen 41, 47 dagegen innerhalb der Sanitärarmatur verlegt.The power supply to the above-mentioned electrical components can be provided by the unit 34, for example. The sensor element 39 is connected to the unit 34 via a further signal line 47. The two signal lines 41, 47 run in the Fig. 1 for reasons of clarity outside of the sanitary fitting. In the actual installation situation, however, the signal lines 41, 47 are laid within the sanitary fitting.

Wie in der Fig.3 gezeigt ist, kann der Bedienknebel 217 in einer ersten Stellbewegung S1 im Uhrzeigersinn von seiner Ruhelage R in eine Heißwasser-Position H verstellt werden. Aus Sicherheitsgründen ist im Bedienknebel 21 ein Schieber 36 gelagert. Für eine Freigabe der obigen Stellbewegung S1 des Bedienknebels 21 muss zunächst der Schieber 36 betätigt werden. Die Stellbewegung S1 erfolgt unter Aufbau einer Rückstellkraft FR, etwa mit Hilfe einer nicht dargestellten Feder. Dadurch ist gewährleistet, dass der Bedienknebel 217 beim Loslassen selbsttätig in seine Ruheposition R zurückgestellt wird.Like in the Fig. 3 is shown, the control knob 217 can be adjusted in a first adjusting movement S 1 clockwise from its rest position R to a hot water position H. For safety reasons, a slide 36 is mounted in the control knob 21. To release the above adjusting movement S 1 of the control knob 21, the slide 36 must first be actuated. The adjusting movement S 1 takes place with the build-up of a restoring force F R , for example with the aid of a spring (not shown). This ensures that the control knob 217 is automatically returned to its rest position R when it is released.

Durch die in der Fig. 3 angedeutete Stellbewegung S1 des Bedienknebels 21 in seine Heißwasser-Position H generiert das Sensorelement 39 ein Signal S, mit dem das Magnetventil 43 aufgesteuert wird. Gleichzeitig wird mit dem Generieren des Signales S das Zeitglied 45 aktiviert. Das Zeitglied 45 schließt nach Ablauf einer vorgegebenen Zeitdauer Δt das Magnetventil. Dies erfolgt auch für den Fall, dass sich der Bedienknebel 217 noch in seiner Heißwasser-Position befindet.Through the in the Fig. 3 indicated adjusting movement S 1 of the control knob 21 in its hot water position H, the sensor element 39 generates a signal S with which the solenoid valve 43 is opened. Simultaneously with the generation of the signal S, the timing element 45 is activated. The timer 45 closes the solenoid valve after a predetermined period of time Δt has elapsed. This also takes place in the event that the control knob 217 is still in its hot water position.

In einer zur ersten Stellbewegung S1 gegenläufigen Stellbewegung S2 entgegen dem Uhrzeigersinn kann der Bedienknebel 217 in weitere Stellposition I bis IV verbracht werden, wie es in der Fig. 4 angedeutet ist. In der Stellposition I kann beispielhaft gekühltes sowie gefiltertes Wasser von der Einheit 34 über die Sanitärarmatur abgezapft werden. In den weiteren Stellposition II bis IV kann dagegen gefiltertes/gekühltes Wasser mit jeweils unterschiedlichem Kohlensäuregehalt abgezapft werden.In a counterclockwise setting movement S 2 opposite to the first setting movement S 1 , the control knob 217 can be moved into further setting positions I to IV, as shown in FIG Fig. 4 is indicated. In the setting position I, for example, cooled and filtered water can be tapped from the unit 34 via the sanitary fitting. In the other setting positions II to IV, on the other hand, filtered / chilled water, each with a different carbon dioxide content, can be tapped.
