Abstract

Water which is in a water tap and emerges out of a water outlet (14) of a water tap (10, 10') is to be irradiated with the aid of a lamp (16, 32). In order not to have to provide the energy required for this externally and not to have to wire up the water tap for this purpose, a generator (20, 20') is provided internally in the water tap, said generator being driven by the water flowing through it and generating the electric current for the lamp. The generator can be designed as a turbine which is arranged directly at the water outlet (14) of the water tap (10').

Wasserhahn und Bestrahlungsverfahren für Wasser in einem WasserhahnFaucet and irradiation process for water in a faucet
Technisches GebietTechnical area
Die Erfindung betrifft einen Wasserhahn, bei dem von einem Wasserleitungsanschluss zu einem Wasseraustritt ein Fließweg für Wasser bereitgestellt ist, und der eine Lampe umfasst, die an den Wasserhahn durchfließendes Wasser elektromagnetische Strahlung abgibt. Die Erfindung betrifft auch ein Verfahren zum Bestrahlen von einen Wasserhahn durchfließendem und aus ihm austretendem Wasser mit elektromagnetischer Strahlung.The invention relates to a faucet in which a flow path for water is provided by a water pipe connection to a water outlet, and comprising a lamp which emits electromagnetic radiation to the water flowing through the faucet. The invention also relates to a method for irradiating electromagnetic radiation flowing through and out of a faucet.
Stand der TechnikState of the art
Aus der US 6,774,584 B2 ist es bekannt, in einem Wasserhahn eine Leuchtdiode anzuordnen, die das aus dem Wasserhahn austretende Wasser mit sichtbarem Licht bestrahlt. Es können auch mehrere Leuchtdioden bereitgestellt sein, die zusammen so angesteuert werden, dass sie eine Färbung erzeugen, die von einer von einem Sensor ermittelten Temperatur des Wassers abhängig ist.From US 6,774,584 B2 it is known to arrange a light-emitting diode in a faucet, which irradiates the water leaving the faucet with visible light. It is also possible to provide a plurality of light-emitting diodes which are actuated together in such a way that they produce a color which is dependent on a temperature of the water determined by a sensor.
Die Leuchtelektroden müssen extern mit Strom versorgt werden. Der hierbei zu betreibende Aufwand ist sehr hoch, denn es muss Betriebssicherheit gewährleistet sein und insbesondere verhindert werden, dass eine Person, die dem Wasserhahn Wasser entnimmt, keine elektrischen Stromschläge erhält. Darstellung der ErfindungThe light-emitting electrodes must be externally supplied with power. The effort to be made in this case is very high, because it must be guaranteed operational safety and in particular to prevent a person who takes the tap water, no electric shocks receives. Presentation of the invention
Es ist Aufgabe der Erfindung, die oben erwähnten Nachteile des Standes der Technik zu überwinden und insbesondere einen Wasserhahn und ein Verfahren der eingangs genannten Art derart weiterzubilden, dass eine erhöhte Betriebssi- cherheit bei gleichzeitiger Einfachheit des Aufbaus gewährleistet ist.It is an object of the invention to overcome the above-mentioned disadvantages of the prior art and in particular a faucet and a method of the type mentioned in such a way that an increased reliability while ensuring ease of construction is guaranteed.
Diese Aufgabe wird durch einen Wasserhahn mit den Merkmalen gemäß Patentanspruch 1 und ein Verfahren mit den Merkmalen gemäß Patentanspruch 9 gelöst.This object is achieved by a faucet having the features according to claim 1 and a method having the features according to claim 9.
Erfindungsgemäß ist im Fließweg des Wasserhahns ein Generator angeordnet, der durch durchfließendes Wasser angetrieben wird. Der Generator ist mit der Lampe verbunden und versorgt diese somit mit für das Abstrahlen elektromagnetischer Strahlung verwendbarer elektrischer Energie.According to the invention, a generator is arranged in the flow path of the faucet, which is driven by flowing water. The generator is connected to the lamp and thus supplies it with usable for the emission of electromagnetic radiation electrical energy.
Durch das interne Bereitstellen der Energiequelle für das Betreiben der Lampe im Wasserhahn entfallen die Nachteile, die im Stand der Technik mit der externen Stromversorgung einhergingen. Die Lösung bleibt kostengünstig, denn ein Generator nach Art eines Fahrraddynamos, der im erfindungsgemäßen Wasserhahn verwendbar ist, kann einfach gebaut sein.The internal provision of the power source for operating the lamp in the tap eliminates the disadvantages associated with the external power supply in the prior art. The solution remains cost-effective, because a generator in the manner of a bicycle dynamo, which can be used in the faucet according to the invention, can be easily constructed.
Bei einer Ausführungsform der Erfindung ist die Lampe eine Ultraviolettlampe. Mit Hilfe einer solchen Ultraviolettlampe, die beispielsweise unter dem Markennamen Xera- dex® von Osram angeboten wird, kann das Wasser im Wasserhahn desinfiziert werden, denn die Ultraviolettstrahlung tötet Bakterien ab. Bei dieser Ausführungsform ist die Lampe innerhalb des Wasserhahns angeordnet, um keine schädliche Ultraviolettstrahlung aus dem Wasserhahn austreten zu lassen.In one embodiment of the invention, the lamp is an ultraviolet lamp. With the help that is offered, for example, under the brand name Xera- dex ® Osram such ultraviolet lamp, the water in the faucet can be disinfected, because the ultraviolet radiation kills bacteria. In this embodiment, the lamp is disposed within the faucet to no to release harmful ultraviolet radiation from the faucet.
Bei einer anderen Ausführungsform gibt die Lampe sichtbares Licht ab, damit das aus dem Wasserhahn fließende Was- ser beleuchtet wird und gegebenenfalls gefärbt wirkt. Naturgemäß gibt die Lampe das sichtbare Licht in Richtung des austretenden Wassers, also in einen aus dem Wasseraustritt austretenden Strahl, ab.In another embodiment, the lamp emits visible light, so that the water flowing from the tap is illuminated and possibly colored. Naturally, the lamp emits the visible light in the direction of the exiting water, that is to say into a jet emerging from the water outlet.
Die Lampe kann eine Leuchtdiode (LED) sein. Mehrere Lam- pen können kombiniert verwendet werden, um unterschiedliche Farbeffekte zu erzeugen. Hierzu müssen die Lampen von einer Steuereinrichtung angesteuert werden.The lamp can be a light emitting diode (LED). Several lamps can be used in combination to create different color effects. For this purpose, the lamps must be controlled by a control device.
Beispielsweise ist die Steuereinleitung bevorzugt dazu ausgelegt, die erzeugte Strommenge zu erfassen und die Lampen abwechselnd oder gleichzeitig so anzusteuern, dass die Färbung des Lichts in dem aus dem Wasseraustritt austretenden Strahl mit der vom Generator erzeugten Strommenge variiert. Die vom Generator erzeugte Strommenge steht in einer eindeutigen Beziehung zur Fließgeschwin- digkeit des Wassers durch den Wasserhahn. Die Färbung kann beispielsweise zwischen dunkelgelb für langsam fließendes Wasser und hellweiß für schnellfließendes Wasser variieren .For example, the control introduction is preferably designed to detect the amount of electricity generated and to control the lamps alternately or simultaneously so that the coloration of the light in the emerging from the water outlet beam varies with the amount of electricity generated by the generator. The amount of electricity generated by the generator is clearly related to the rate of flow of water through the faucet. For example, the color may vary between dark yellow for slowly flowing water and light white for fast flowing water.
Alternativ zu der Variation entsprechend der Fließge- schwindigkeit kann auch die Temperatur berücksichtigt werden. Es wird dann ein Temperatursensor im Fließweg des Wassers bereitgestellt, und die Steuereinrichtung empfängt die Signale des Temperatursensors und steuert die Lampen entsprechend abwechselnd oder gleichzeitig so an, dass die Färbung des Lichts in dem aus dem Wasseraustritt austretenden Strahl mit der Temperatur des Wassers variiert. Außer von Fließgeschwindigkeit und Temperatur kann die Farbvariation von einer beliebigen Messgröße abhängig sein .As an alternative to the variation according to the flow rate, the temperature can also be taken into account. A temperature sensor is then provided in the flow path of the water, and the controller receives the signals from the temperature sensor and controls the lamps alternately or simultaneously so that the color of the light in the water exit leaking jet varies with the temperature of the water. Apart from flow velocity and temperature, the color variation can be dependent on any measured variable.
Im einfachsten Fall der Ausführungsform der Erfindung um- fasst der Generator eine (kleine) Turbine. Diese kann im Innern des Wasserhahns bereitgestellt sein. Bevorzugt ist die Turbine unmittelbar am Wasseraustritt angeordnet. Dadurch kann auf einen sonst üblichen Perlator® verzichtet werden.In the simplest case of the embodiment of the invention, the generator comprises a (small) turbine. This can be provided inside the faucet. Preferably, the turbine is arranged directly on the water outlet. This eliminates the need for a conventional Perlator ® .
Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass durch das durch den Wasserhahn fließende Wasser ein Generator angetrieben wird, der (den) elektrischen Strom für alle Lampen erzeugt.The inventive method is characterized in that the water flowing through the faucet, a generator is driven, which generates (the) electric current for all lamps.
Der Sonderfall, dass mehrere Lampen bereitgestellt werden, ist insbesondere dann sinnvoll, wenn die elektromagnetische Strahlung sichtbares Licht umfasst. Dann kann dessen Färbung durch die abwechselnde oder gleichzeitige Verwendung mehrerer Lampen variabel festgelegt werden, z. B. in Abhängigkeit von der vom Generator erzeugten Strommenge (und damit typischerweise der Fließgeschwindigkeit des Wassers durch den Wasserhahn) , oder auch von der Temperatur des Wassers.The special case that several lamps are provided is particularly useful when the electromagnetic radiation comprises visible light. Then its color can be variably determined by the alternate or simultaneous use of multiple lamps, z. B. depending on the amount of electricity generated by the generator (and thus typically the flow rate of water through the faucet), or from the temperature of the water.
Kurze Beschreibung der Zeichnung (en)Short description of the drawing (s)
Nachfolgend werden bevorzugte Ausführungsformen der Er- findung unter Bezug auf die Zeichnung beschrieben, wobeiHereinafter, preferred embodiments of the invention will be described with reference to the drawings, wherein
Fig. 1 eine erste Ausführungsform der Erfindung und Fig. 2 eine zweite Ausführungsform der Erfindung veranschaulicht .Fig. 1 shows a first embodiment of the invention and Fig. 2 illustrates a second embodiment of the invention.
Bevorzugte Ausführung der ErfindungPreferred embodiment of the invention
Ein in Fig. 1 gezeigter, im Ganzen mit 10 bezeichneter Wasserhahn gemäß einer erfindungsgemäßen Ausführungsform umfasst wie jeder Wasserhahn einen Wasserleitungsan- schluss 12 und einen Wasseraustritt 14. Im Bereich des Wasseraustritts 14 ist eine Lichtquelle 16 angeordnet, welche sichtbares Licht abstrahlt, und zwar in einen aus dem Wasserhahn 10, insbesondere aus dem Wasseraustritt 14, austretenden Wasserstrahl 18. Der Lichtquelle 16 muss nun ständig elektrische Energie zugeführt werden. Anstatt außerhalb des Wasserhahns Stromquellen bereitzustellen, wird die Frage der Energieversorgung der Lichtquelle 16 intern innerhalb des Wasserhahns 10 gelöst: Im Fließweg des Wassers zwischen dem Wasserleitungsanschluss 12 und dem Wasseraustritt 14 ist ein Generator 20 angeordnet, der beispielsweise eine herkömmliche Turbine (in Fig. 1 nicht gezeigt) umfasst. Der Generator 20 ist über eine Leitung 22 mit der Lichtquelle 16 verbunden.A faucet according to an embodiment of the invention shown in FIG. 1, generally designated 10, comprises, like each faucet, a water pipe connection 12 and a water outlet 14. In the region of the water outlet 14, a light source 16 is arranged which emits visible light, namely one from the faucet 10, in particular from the water outlet 14, exiting water jet 18. The light source 16 must now be constantly supplied with electrical energy. Instead of providing power sources outside the faucet, the issue of powering the light source 16 internally within the faucet 10 is solved: In the flow path of the water between the water conduit connection 12 and the water outlet 14, there is arranged a generator 20, for example a conventional turbine (shown in FIG not shown). The generator 20 is connected via a line 22 to the light source 16.
In vorteilhafter Weise ist im Bereich der Lichtquelle 16 auch eine Steuereinrichtung 24 angeordnet, die die Stromzufuhr zur Lichtquelle 16 steuert. So kann vorgesehen sein, dass die Lichtquelle 16 immer die gleiche Menge an Strom erhält, und zwar ab einer Mindestfließgeschwindig- keit des Wassers im Wasserhahn 10. Es kann auch vorgesehen sein, dass bei erhöhter Fließgeschwindigkeit die Lichtquelle 16 mehr Strom erhält und dadurch gegebenenfalls heller leuchtet. Die Lichtquelle 16 kann mehrere kleine Lampen umfassen (nicht gezeigt) , und es kann vor- gesehen sein, dass bei Erhöhung der durch den Generator 20 erzeugten Strommenge die Zahl der leuchtenden Lampen erhöht wird. Schließlich können die einzelnen Lampen auch unterschiedliche Farbspektren aufweisen. Die Steuer- einrichtung übernimmt dann die Aufgabe der Ansteuerung der einzelnen Lampen, um die Farbspektren mit bestimmter Gewichtung zu mischen, die unterschiedlichen Lampen abwechselnd anzusteuern etc. So kann bewirkt werden, dass bei Variationen der vom Generator 20 erzeugten Strommenge auch die Farbe des abgegebenen Lichts geändert wird. Die Strommenge variiert insbesondere mit der Fließgeschwindigkeit des Wassers. Insbesondere kann vorgesehen sein, dass bei kleinen Fließgeschwindigkeiten eher als dunkel empfundene Farben wie violett und blau abgegeben werden, bei höheren Fließgeschwindigkeiten dann Farben wie rot und grün und bei sehr hohen Fließgeschwindigkeiten als hell empfundene Farben wie gelb oder weiß abgegeben werden .Advantageously, a control device 24 is arranged in the region of the light source 16, which controls the power supply to the light source 16. It can thus be provided that the light source 16 always receives the same amount of current, starting from a minimum flow velocity of the water in the tap 10. It can also be provided that the light source 16 receives more current at an increased flow rate and thus possibly brighter shines. The light source 16 may comprise a plurality of small lamps (not shown), and it may be be seen that increases the amount of electricity generated by the generator 20, the number of luminous lamps is increased. Finally, the individual lamps can also have different color spectrums. The control device then takes on the task of driving the individual lamps to mix the color spectra with a certain weighting, to control the different lamps alternately, etc. Thus, it can be effected that with variations of the amount of electricity generated by the generator 20 and the color of the emitted light will be changed. The amount of electricity varies in particular with the flow rate of the water. In particular, it can be provided that at low flow velocities rather than dark perceived colors such as violet and blue are discharged, at higher flow rates then colors such as red and green and delivered at very high flow velocities as bright perceived colors such as yellow or white.
Fig. 2 zeigt einen im Ganzen mit 10' bezeichneten Wasser- hahn gemäß einer zweiten Ausführungsform der Erfindung. Im Unterschied zu der Ausführungsform gemäß Fig. 1 ist ein Generator 20' nicht im Innern des Wasserhahns 10' vorgesehen, sondern direkt am Wasseraustritt 14 des Wasserhahns 10' . In der Vergrößerung, welche Fig. 2 gleich- zeitig mit der Grunddarstellung zeigt, ist zu sehen, dass der Generator 20' im Wesentlichen aus einer Turbine mit Turbinenblättern 26 besteht. Die Turbinenblätter 26 sind an einem Turbinenrad 27 angeordnet, das sich um eine Drehachse 28 dreht. An der Außenseite des Turbinenrades 27 ist eine Platine 30 angeordnet, welche elektronische Steuereinheiten trägt. Die Platine 30 übernimmt bei dem Wasserhahn 10' die Funktion der Steuereinrichtung 24, die der Wasserhahn 10 aus Fig. 1 hat. Mittig auf der Platine 30, und somit im Durchstoßpunkt der Achse 28 durch die Platine 30, ist eine Leuchtdiode 32 angeordnet.FIG. 2 shows a tap, generally designated 10 ', according to a second embodiment of the invention. In contrast to the embodiment according to FIG. 1, a generator 20 'is not provided inside the faucet 10' but directly at the water outlet 14 of the faucet 10 '. In the enlargement, which shows FIG. 2 simultaneously with the basic illustration, it can be seen that the generator 20 'consists essentially of a turbine with turbine blades 26. The turbine blades 26 are arranged on a turbine wheel 27, which rotates about a rotation axis 28. On the outside of the turbine wheel 27, a circuit board 30 is arranged, which carries electronic control units. The board 30 takes over in the Faucet 10 ', the function of the control device 24, the tap 10 of FIG. 1 has. Centered on the board 30, and thus in the puncture point of the axis 28 through the board 30, a light-emitting diode 32 is arranged.
Bei der Ausführungsform aus Fig. 2 entfällt eine durch den Wasserhahn geführte elektrische Leitung nach Art der elektrischen Leitung 22 im Wasserhahn 10 beim Wasserhahn 10' völlig. Das Anordnen der Turbine unmittelbar an dem Wasseraustritt 14 hat auch den Vorteil, dass ein sonst an dieser Stelle üblicher Perlator® überflüssig wird. Eine sich drehende Turbine hat nämlich einen fast identischen Effekt wie ein Perlator®. Bevorzugt wird die gesamte Anordnung in Form eines handelsüblichen Perlators® hergestellt, um eine einfache Austauschmöglichkeit zu gewähr- leisten. Die Leuchtdiode 32 beleuchtet den Wasserstrahl 18 beim Wasserhahn 10', genauso wie die Lichtquelle 16 den Wasserstrahl 18 beim Wasserhahn 10.In the embodiment of Fig. 2 eliminates a run through the faucet electric line in the manner of the electrical line 22 in the tap 10 at the tap 10 'completely. Arranging the turbine directly to the water outlet 14 has the advantage that an otherwise becomes unnecessary at this point conventional aerator ® also the advantage. A rotating turbine has almost the same effect as a Perlator ® . Preferably, the entire assembly is made in the form of a commercial Perlator ® , in order to ensure a simple exchange possibility. The LED 32 illuminates the water jet 18 at the tap 10 ', as well as the light source 16, the water jet 18 at the tap 10th
Die Idee, einen aus einem Wasserhahn austretenden Wasserstrahl zu beleuchten, wird vorliegend dadurch erst wirk- lieh praktikabel, dass die Frage der Energiezufuhr elegant durch das Bereitstellen des Generators 20 bzw. 20' im Wasserhahn 10 bzw. 10' gelöst wird. The idea of illuminating a jet of water emanating from a tap is in this case only really practicable, that the question of energy supply elegantly by the provision of the generator 20 or 20 'in the tap 10 or 10' is solved.
