Abstract

A valve system in which a magnetic valve is in series with a manually-operated valve and contact with the handle of the manually-operated valve initiates flow via the electronic controller whereas, upon loss of contact, a proximity detector controls the magnetic valve when an object, such as a user's hand, is in range. The manual contact is superordinate and proximity detection is subordinate and the proximity detector remains permanently switched on during the operating duration.

Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 7 angegeben.Further embodiments of the invention are in the claims 2 to 7 specified.

Mit den vorgeschlagenen Maßnahmen kann die Wasserauslaufeinrichtung erheblich vereinfacht werden, da bei dem mechanisch von Hand stellbaren Ventil lediglich ein Berührungssensor erforderlich ist. Es hat sich darüber hinaus gezeigt, dass die Steuerelektronik mit der Detektionseinrichtung relativ kostengünstig auch im Dauerbetrieb eingesetzt werden kann.With the proposed measures, the water outlet device be significantly simplified because at the mechanically adjustable valve only one Touch sensor is required. It has about it also shown that the control electronics with the detection device relatively inexpensive even in continuous operation can be used.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung angegeben. In der einzigen Figur ist eine an einen Waschtisch anmontierte Wasserzapfarmatur in Form eines Eingriffmischventils schematisch dargestellt, wobei die Steuerelektronik und das von der Steuerelektronik geschaltete Ventil unterhalb des Waschtischs angeordnet sind.An embodiment of the invention is in the drawing specified. In the single figure there is one on one Basin-mounted water tap fitting in the form of a Engagement mixer valve shown schematically, the Control electronics and that switched by the control electronics Valve arranged below the washstand are.

Die in der Zeichnung dargestellte Wasserzapfarmatur wird von einem Armaturenkörper 2, einem als Mischventilkartusche ausgebildeten ersten Ventil 3 sowie einem Handgriff 1 gebildet. An einem Waschtisch 7 ist im Bereich einer Öffnung 70 der Armaturenkörper 2 in herkömmlicher Weise befestigt, wobei durch die Öffnung 70 ausserdem die beiden Anschlussleitungen 21,22 für Kalt- und Warmwasser hindurchgeführt sind. Die Anschlussleitungen 21,22 sind im Armaturenkörper 2 mit dem Ventil 3 verbunden. Das Ventil 3 ist über einen Stellhebel 30 mit dem Handgriff 1 verbunden, wobei mit einem Verschwenken um eine senkrecht zur Mittelachse 13 angeordneten Achse in Richtung des Pfeils 11 die Durchflussmenge pro Zeiteinheit in einem ersten Freiheitsgrad und in einem zweiten Freiheitsgrad mit einem Drehen um die Mittelachse 13 in Richtung des Pfeils 12 das Mischungsverhältnis von Kalt- und Warmwasser mit dem Handgriff 1 einstellbar ist. Das in dem Ventil 3 erzeugte Mischwasser wird über ein Wasserauslassmundstück 23 vom Armaturenkörper 1 als Freistrahl abgegeben.The water tap shown in the drawing is from a valve body 2, one as a mixing valve cartridge trained first valve 3 and one Handle 1 formed. At a vanity 7 is in the area an opening 70 of the valve body 2 in a conventional manner Way, through opening 70 also the two connection lines 21, 22 for cold and hot water are led through. The connecting lines 21, 22 are in the valve body 2 with the valve 3 connected. The valve 3 is via an adjusting lever 30 connected to the handle 1, with a pivoting arranged perpendicular to the central axis 13 Axis in the direction of arrow 11 is the flow rate per unit of time in a first degree of freedom and in a second degree of freedom with a turn around the Center axis 13 in the direction of arrow 12 the mixing ratio of cold and hot water with the handle 1 is adjustable. The mixed water generated in the valve 3 is via a water outlet mouthpiece 23 from the fitting body 1 given as a free jet.

Ausserdem ist in dem Armaturenkörper 2 im unteren Bereich eine Detektionseinrichtung 6 angeordnet, mit der festgestellt werden kann, ob ein Gegenstand, z. B. die Hand eines Benutzers, sich in einem bestimmten Erfassungsbereich befindet.
Schließlich ist am Griff 1 im Bereich des Griffarms 10 ein Sensor 100 an der Oberfläche ausgebildet, mit dem eine Berührung, insbesondere durch die Hand des Benutzers, feststellbar ist.
Der Sensor 100 ist mit einer Leitung 50 und die Detektionseinrichtung 6 mit einer Leitung 51 mit einer unterhalb des Waschtisches 7 angeordneten Steuerelektronik 5 verbunden.In addition, a detection device 6 is arranged in the valve body 2 in the lower region, with which it can be determined whether an object, for. B. the hand of a user, is in a certain detection range.
Finally, a sensor 100 is formed on the surface of the handle 1 in the region of the handle arm 10, with which a contact, in particular by the user's hand, can be determined.
The sensor 100 is connected to a line 50 and the detection device 6 to a line 51 with control electronics 5 arranged below the washstand 7.

Die Anschlussleitungen 21,22 sind jeweils an einem Eckventil 8 des Kaltwasser- und Warmwasserversorgungsleitungsnetzes angeschlossen (in der Zeichnung ist nur ein Eckventil gezeigt, das zweite Eckventil befindet sich hinter der Zeichnungsebene). Stromabwärts hinter dem Eckventil ist in jeder der beiden Leitungen jeweils ein Schmutzfangsieb 25 und ein Rückflussverhinderer 24 angeordnet, an dem sich das zweite Ventil 4 in Zwillingsbauweise mit separat je einem Durchgang für Kalt- und Warmwasser anschließt. Das Ventil 4 wird von einem elektromagnetisch betätigten Pilotventil 40 in Offen- oder Schließstellung geschaltet. Das Pilotventil 40 ist wiederum mit einer Leitung 52 mit der Steuerelektronik 5 verbunden.The connecting lines 21, 22 are each on a corner valve 8 of the cold water and hot water supply network connected (in the drawing there is only one Corner valve shown, the second corner valve is located behind the drawing level). Downstream behind the The corner valve is one in each of the two lines Dirt trap 25 and a non-return valve 24 are arranged, on which the second valve 4 in twin construction with a separate passage for cold and Hot water connects. The valve 4 is one electromagnetically operated pilot valve 40 in open or closed position switched. The pilot valve 40 is again with a line 52 to the control electronics 5 connected.

Die Steuerelektronik 5 ist hierbei so ausgelegt, dass sie im Dauerbetrieb arbeitet und dass ein durch eine Berührung des Sensors 100 erzeugtes Signal Vorrang vor einem von der Detektionseinrichtung 6 erzeugten Signal hat. Die elektrische Energieversorgung für die Steuerelektronik 5, die Detektionseinrichtung 6 sowie für das Pilotventil 40 erfolgt in dem Ausführungsbeispiel durch Anordnung einer oder mehrerer Batterien in der Steuerelektronik 5. Selbstverständlich kann die Steuerelektronik aber auch an ein elektrisches Versorgungsleitungsnetz angeschlossen sein.The control electronics 5 is designed so that it works in continuous operation and that one by one Touch of the sensor 100 generated signal takes precedence a signal generated by the detection device 6 Has. The electrical power supply for the control electronics 5, the detection device 6 and for that Pilot valve 40 takes place in the exemplary embodiment Arrangement of one or more batteries in the control electronics 5. Of course, the control electronics but also to an electrical supply line network be connected.

Die vorstehend beschriebene Wasserauslaufeinrichtung hat folgende Funktionsweise:
In der in der Zeichnung dargestellten Position des Handgriffs 1 befindet sich das erste Ventil 3 in seiner Schließstellung. Da auch der Sensor 100 vom Benutzer nicht berührt wird, wird von der Steuerelektronik 5 über das Pilotventil 40 das zweite Ventil 4 (Zwillingsventil) in Absperrstellung gehalten.
Berührt ein Benutzer den Sensor 100 am Handgriff 1, so wird von der Steuerelektronik 5 über das Pilotventil 40 veranlasst, dass das Ventil 4 (Zwillingsventil) in Offenstellung gebracht wird und so lange in Offenstellung verharrt, wie vom Benutzer der Sensor 100 berührt wird. In dieser Steuerstellung kann von dem Benutzer die Wasserauslaufeinrichtung als von Hand stellbares Eingriffmischventil benutzt werden. Durch ein Verschwenken des Handgriffs 1 in Pfeilrichtung 11 wird das Ventil 3 aus seiner Absperrposition zunehmend in die voll geöffnete Position bewegt, so dass über das Wasserauslassmundstück 23 zunehmend mehr Wasser als Freistrahl austritt. Durch ein Drehen des Handgriffs 1 in Richtung des Pfeils 12 kann das Mischungsverhältnis des zufließenden Kalt- und Warmwassers bzw. die Temperatur des über das Wasserauslassmundstück 23 abgegebene Mischwasser eingestellt werden.
Wird vom Benutzer die Berührung des Sensors 100 in einer Offenstellung des Ventils 3 unterbrochen, so wird danach von der Detektionseinrichtung 6 über die Steuereinrichtung 5 der Wasserausfluss gesteuert. Befindet sich hierbei im Erfassungsbereich der Detektionseinrichtung 6 ein Gegenstand, so veranlasst die Steuerelektronik 5 über das Pilotventil 40, dass das Ventil 4 (Zwillingsventil) in Offenstellung verharrt. Wird dagegen kein Gegenstand detektiert, so veranlasst die Steuerelektronik 5 über das Pilotventil 40, dass das Ventil 4 (Zwillingsventil) in die Absperrstellung gebracht wird. Wird zu einem späteren Zeitpunkt erneut ein Gegenstand in den Erfassungsbereich der Detektionseinrichtung 6 gebracht, so veranlasst die Steuerelektronik 5 über das Pilotventil 40 eine erneute Öffnung des Ventils 4 (Zwillingsventil) für die Zeitdauer in der von der Detektionseinrichtung 6 ein Gegenstand in dem Erfassungsbereich detektiert wird. Die Wasserauslaufeinrichtung arbeitet somit als berührungslose Wasserauslaufsteuerung.
Bei dem vorstehend beschriebenen Ausführungsbeispiel ist das zweite Ventil 4 als Zwillingsventil stromaufwärts vor dem ersten, von Hand gesteuerten Ventil 3 angeordnet. Hierbei kann auch das Zwillingsventil mit zwei Pilotventilen 40 versehen sein, so dass zwei räumlich getrennte Ventile 4 bestehen, die jeweils an einem Eckventil 8 für Kalt- oder Warmwasser anschließbar sind.
Selbstverständlich kann aber auch das von der Steuerelektronik stellbare zweite Ventil auch stromabwärts hinter dem von Hand stellbaren ersten Ventil angeordnet werden.
Auch kann die Steuerelektronik anstatt unterhalb des Waschtisches unmittelbar in dem Armaturenkörper der Wasserauslaufeinrichtung zusammen mit der Detektionseinrichtung integriert werden. Als Detektionseinrichtung kann beispielsweise ein Infrarotlicht aussendender und empfangender Annäherungsschalter vorgesehen werden. Schließlich kann die erfindungsgemäße Wasserauslaufeinrichtung auch bei einer Wasserzapfeinrichtung mit einem von Hand stellbaren Absperr- und Mengendosierventil eingesetzt werden.The water outlet device described above works as follows:
In the position of the handle 1 shown in the drawing, the first valve 3 is in its closed position. Since the sensor 100 is not touched by the user either, the control electronics 5 hold the second valve 4 (twin valve) in the shut-off position via the pilot valve 40.
If a user touches the sensor 100 on the handle 1, the control electronics 5 via the pilot valve 40 cause the valve 4 (twin valve) to be brought into the open position and remain in the open position as long as the user touches the sensor 100. In this control position, the water outlet device can be used by the user as a manually adjustable engagement mixer valve. By pivoting the handle 1 in the direction of the arrow 11, the valve 3 is increasingly moved from its shut-off position to the fully open position, so that more and more water emerges as a free jet via the water outlet mouthpiece 23. By turning the handle 1 in the direction of arrow 12, the mixing ratio of the incoming cold and hot water or the temperature of the mixed water discharged via the water outlet mouthpiece 23 can be set.
If the user stops touching the sensor 100 in an open position of the valve 3, the water outflow is then controlled by the detection device 6 via the control device 5. If there is an object in the detection range of the detection device 6, the control electronics 5, via the pilot valve 40, causes the valve 4 (twin valve) to remain in the open position. If, on the other hand, no object is detected, the control electronics 5 via the pilot valve 40 cause the valve 4 (twin valve) to be brought into the shut-off position. If an object is again brought into the detection area of the detection device 6 at a later time, the control electronics 5 causes the valve 4 (twin valve) to open again via the pilot valve 40 for the period of time in which an object is detected by the detection device 6 in the detection area . The water outlet device thus works as a contactless water outlet control.
In the exemplary embodiment described above, the second valve 4 is arranged as a twin valve upstream of the first, manually controlled valve 3. Here, the twin valve can also be provided with two pilot valves 40, so that there are two spatially separate valves 4, each of which can be connected to a corner valve 8 for cold or hot water.
Of course, the second valve that can be set by the control electronics can also be arranged downstream behind the manually adjustable first valve.
The control electronics can also be integrated directly in the fitting body of the water outlet device together with the detection device instead of underneath the washstand. For example, a proximity switch emitting and receiving infrared light can be provided as the detection device. Finally, the water outlet device according to the invention can also be used with a water dispensing device with a manually adjustable shut-off and quantity metering valve.
