Abstract

The plumbing fixture, which can be actuated without physical contact, has a water line that is connected to a source of water and has a water outlet. A shut-off valve is disposed in the water line downstream of a mixer valve. A control unit controls the shut-off valve as a function of control signals from a proximity-sensitive sensor. A turbine is disposed in the water line for supplying electrical energy to the control unit. Permanent magnets are distributed equidistantly about an outer periphery of a wheel of the turbine. At the level of the permanent magnets, at least two magnet coils are provided in a tubular section of the water line. The coils cooperate with the permanent magnets to form a generator.

Description

Die Erfindung bezieht sich auf eine berührungslos betätigbare Sanitärarmatur mit einem an eine Wasserleitung angeschlossenen Wasserauslauf, einem in diese eingesetzten Mischventil und einem diesem vorgeschalteten, durch einen annäherungsempfindlichen Sensor steuerbaren Absperrventil, das mittels eines Steuergerätes in Abhängigkeit von den Steuersignalen des Sensors betätigbar ist, wobei zur Versorgung des Steuergerätes mit elektrischer Energie eine in die Wasserleitung eingesetzte Turbine und ein dieser zugeordneter, vorzugsweise an einen Energiespeicher angeschlossener Generator vorgesehen sind.The invention relates to a contactlessly operated sanitary fitting with a water outlet connected to a water outlet, a mixing valve inserted therein and a shut-off valve which can be controlled by a proximity sensor and which can be actuated by means of a control device as a function of the control signals of the sensor Supply of the control unit with electrical energy, a turbine inserted into the water line and an associated generator, preferably connected to an energy store, are provided.

Durch die DE-C1- 39 05 759 ist eine Sanitärarmatur dieser Art bekannt. Im Bereich der Turbine ist die Wasserleitung hierbei als Ringkanal ausgebildet, in den die Schaufeln der Turbine hineinragen. Und innerhalb des Ringkanals ist in einem gesonderten Gehäuse der Generator, die die Schaufeln der Turbine tragenden Welle sowie ein Übersetzungsgetriebe angeordnet.A sanitary fitting of this type is known from DE-C1- 39 05 759. In the area of the turbine, the water pipe is designed as an annular channel into which the blades protrude into the turbine. And within the ring channel, the generator, the shaft carrying the blades of the turbine and a transmission gear are arranged in a separate housing.

Diese ohne Anschluß an ein Stromnetz funktionsfähige Sanitärarmatur hat sich zwar bewährt, da jedoch der Generator mit in die Wasserleitung eingebaut ist, muß die elektrische Energie über Schleifkontakte von diesem abgenommen und aus der Wasserleitung herausgeführt werden. Bei der geringen durch das strömende Wasser umwandelbaren Energiemenge sind die dabei auftretenden Verluste erheblich, auch ist die Abdichtung des Generators oftmals mit Schwierigkeiten verbunden, so daß ein störungs- und wartungsfreier Betrieb über einen längeren Zeitraum nicht gegeben ist.This sanitary fitting, which is functional without connection to a power supply, has proven itself, but since the generator is built into the water pipe, the electrical energy must be removed from it via sliding contacts and led out of the water pipe. With the small amount of energy that can be converted by the flowing water, the losses that occur are considerable, and the sealing of the generator is often associated with difficulties, so that trouble-free and maintenance-free operation over a longer period of time is not possible.

Aufgabe der Erfindung ist es daher, eine berührungslos betätigbare Sanitärarmatur der eingangs genannten Gattung in der Weise auszugestalten, daß die von dem Generator abgegebene elektrische Energie problemlos und nahezu verlustfrei unmittelbar dem Steuergerät oder dem Energiespeicher zuzuführen ist und daß keine besonderen Abdichtungen des Generators oder sonstiger Bauteile vorzunehmen sind. Vor allem aber soll erreicht werden, daß der Generator mit hoher Drehzahl, ohne daß dazu ein mit Verlusten behaftetes Übersetzungsgetriebe erforderlich ist, arbeiten kann, so daß eine gute Ausnutzung der Strömungsenergie des Wassers und demnach ein hoher Wirkungsgrad gegeben ist. Der dazu erforderliche Fertigungsaufwand soll gering gehalten werden, auch sollen die in die Wasserleitung einzusetzenden Teile einfach in ihrer konstruktiven Ausgestaltung sein und klein bauen, damit ein störungs- und wartungsfreier Betrieb über einen langen Zeitraum gewährleistet ist und die Sanitärarmatur nahezu unbeschränkt eingesetzt und auch nachträglich eingebaut werden kann.The object of the invention is therefore to design a contactlessly operated sanitary fitting of the type mentioned in such a way that the electrical energy emitted by the generator can be fed directly to the control unit or the energy store without problems and almost without loss and that no special seals of the generator or other components are to be made. Above all, however, it should be achieved that the generator can work at high speed without the need for a lossy transmission gear, so that a good utilization of the flow energy of the water and therefore a high efficiency is given. The manufacturing effort required for this should be kept low, and the parts to be inserted into the water pipe should also be simple in their structural design and small in size, thus ensuring trouble-free and maintenance-free operation over a long period of time is guaranteed and the sanitary fitting can be used almost without restriction and can also be retrofitted.

Gemäß der Erfindung wird dies bei einer Sanitärarmatur der vorgenannten Art dadurch erreicht, daß das Laufrad der Turbine unmittelbar in dem Wasserführungskanal der Wasserleitung um eine sich in Strömungsrichtung erstrekkende Achse rotierend antreibbar gelagert und im äußeren Bereich mit mehreren über den Umfang gleichmäßig verteilt angeordneten Dauermagneten bestückt ist, und daß in die Wandung der Wasserleitung oder auf dieser in Höhe der Dauermagnete zwei oder mehrere in dessen Achsrichtung ausgerichtete Magnetspulen eingesetzt sind, die im Zusammenwirken mit den in dem Laufrad der Turbine angeordneten Dauermagneten den Generator bilden.According to the invention, this is achieved in a sanitary fitting of the aforementioned type in that the impeller of the turbine is mounted so as to be drivable directly in the water duct of the water pipe about an axis extending in the direction of flow and is equipped in the outer region with a plurality of permanent magnets arranged uniformly distributed over the circumference , and that in the wall of the water pipe or on this at the level of the permanent magnets two or more magnetic coils aligned in its axial direction are used, which form the generator in cooperation with the permanent magnets arranged in the impeller of the turbine.

Angebracht ist es hierbei, die Wasserleitung mit einer ersten und einer zweiten durchströmbaren Zwischenwand zu versehen, zwischen denen das Laufrad der Turbine angeordnet ist und dieses mittels Zentrierspitzen und Zentrierbohrungen drehbar in den Zwischenwänden abzustützen.It is appropriate here to provide the water pipe with a first and a second flow-through intermediate wall, between which the impeller of the turbine is arranged and which is rotatably supported in the intermediate walls by means of centering tips and centering holes.

Um auf einfache Weise eine hohe Turbinendrehzahl zu ermöglichen, sollten die dem Laufrad der Turbine vorgeschaltete erste Zwischenwand mit einer oder mehreren in deren äußeren Bereich in diese eingearbeiteten und vorzugsweise in Strömungsrichtung geneigt verlaufend angeordneten Düsenöffnungen und das Laufrad mit auf dem Durchmesserbereich der Düsenöffnungen der ersten Zwischenwand angeordneten vorzugsweise achssenkrecht zu diesen geneigt verlaufenden Leitschaufeln versehen sein, wobei die Anzahl der Leitschaufeln des Laufrades der Anzahl der in die erste Zwischenwand eingearbeiteten Düsenöffnungen entsprechen sollte.In order to enable a high turbine speed in a simple manner, the first intermediate wall upstream of the impeller of the turbine should have one or more nozzle openings incorporated into the outer region thereof and preferably arranged inclined in the direction of flow, and the impeller with the diameter region of the nozzle openings of the first intermediate wall arranged preferably axially perpendicular to these inclined guide vanes, the number of guide vanes of the impeller should correspond to the number of nozzle openings machined into the first intermediate wall.

Angezeigt ist es auch, das Laufrad der Turbine mit einem axial abstehenden Ansatz auszustatten, der in eine Freisparung der Wasserleitung eingreift und in dem die Dauermagnete des vorzugsweise als Synchrongenerator ausgebildeten Generators eingesetzt sind.It is also indicated to equip the impeller of the turbine with an axially protruding shoulder, which engages in a cutout in the water pipe and in which the permanent magnets of the generator, which is preferably designed as a synchronous generator, are inserted.

Nach einer andersartigen Ausgestaltung kann das Laufrad der Turbine mit radial innerhalb der Dauermagnete angeordneten von dem strömenden Medium beaufschlagbaren Leitschaufeln versehen sein.According to another design, the impeller of the turbine can be provided with guide vanes arranged radially inside the permanent magnets and capable of being acted upon by the flowing medium.

Zur Reduzierung der Strömungswiderstände können die beiden Zwischenwände auf den Außenseiten und/oder das Laufrad der Turbine auf der der ersten Zwischenwand abgekehrten Seite kegelförmig gestaltete strömungsgünstig geformte Ansatzstücke aufweisen.To reduce the flow resistances, the two intermediate walls on the outer sides and / or the impeller of the turbine on the side facing away from the first intermediate wall can have conically shaped, aerodynamically shaped extension pieces.

Die beiden Zwischenwände und das zwischen diesen eingesetzte Laufrad der Turbine können zweckmäßigerweise in einer kegelig in die Wasserleitung eingeformten Erweiterung angeordnet werden.The two partition walls and the turbine impeller inserted between them can be expediently arranged in a conical extension formed in the water pipe.

Aus ökologischen Gründen und um Bauraum einzusparen kann der Energiespeicher durch einen Kondensator gebildet sein.For ecological reasons and in order to save installation space, the energy store can be formed by a capacitor.

Wird eine Sanitärarmatur gemäß der Erfindung ausgebildet, so ist nicht nur eine kompakte Baueinheit gegeben, die nahezu überall und auch nachträglich einsetzbar ist und die einen störungsfreien Betrieb ohne Anschluß an ein Stromnetz ermöglicht, sondern die elektrische Energie kann auch problemlos und ohne größere Verluste von dem Generator zu der Steuereinheit bzw. dem Energiespeicher übergeführt werden. Schleifkontakte sind dazu nicht erforderlich, auch sind keine elektrischen Kabel in der Wasserleitung anzuordnen, die in diese eingesetzte Spulen sind vielmehr ortsfest und problemlos mit der Steuereinheit bzw. dem Energiespeicher elektrisch zu verbinden. Und da den Schaufeln des Turbinenlaufrades bei Entnahme von Wasser dieses aus Düsenöffnungen und somit mit hoher Geschwindigkeit zuströmt, sind auch hohe Drehzahlen erzielbar. Zum Betrieb der Sanitärarmatur steht demnach stets eine ausreichende Energiemenge zur Verfügung. Trotz des geringen Bauaufwandes sind somit ein hoher Ausnutzungsgrad der in dem Wasser enthaltenen Energie gegeben und ein störungs- und wartungsfreier Betrieb über einen langen Zeitraum gewährleistet, ohne daß Batterien auszuwechseln und zu entsorgen sind.If a sanitary fitting is designed according to the invention, there is not only a compact structural unit which can be used almost anywhere and also retrospectively and which enables trouble-free operation without connection to a power network, but the electrical energy can also be easily and without major losses from the Generator are transferred to the control unit or the energy store. Sliding contacts are not required for this, nor are there any electrical cables to be arranged in the water line, the coils inserted into them are rather stationary and can be electrically connected to the control unit or the energy store without any problems. And there the shovels of the Turbine impeller when water is withdrawn from the nozzle openings and thus flows at high speed, high speeds can also be achieved. A sufficient amount of energy is therefore always available to operate the sanitary fitting. Despite the low construction costs, a high degree of utilization of the energy contained in the water is provided and trouble-free and maintenance-free operation is ensured over a long period of time without batteries having to be replaced and disposed of.

Die in Figur 1 dargestellte Sanitärarmatur 1 weist ein Mischventil 6 sowie ein diesem nachgeschaltetes Absperrventil 8 auf, das mittels eines Sensors 10 steuerbar ist. Das aus einer Kaltwasserleitung 2 und einer Warmwasserleitung 3 über Zweigleitungen 4 und 5 dem Mischventil 6 zugeführte Wasser wird in diesem entsprechend der eingestellten Wasserverteilung gemischt und kann aus einem Wasserauslauf 9, dem das gemischte Wasser über eine Wasserleitung 7 zugeführt wird, ausströmen, sobald das Absperrventil 8 in Abhängigkeit von einem von dem Sensor 10 abgegebenen Impuls geöffnet wird.The sanitary fitting 1 shown in FIG. 1 has a mixing valve 6 and a shut-off valve 8 connected downstream thereof, which can be controlled by means of a sensor 10. That from a cold water pipe 2 and a hot water pipe 3 via branch pipes 4 and 5 to the mixing valve 6 supplied water is mixed in this in accordance with the set water distribution and can flow out of a water outlet 9, to which the mixed water is supplied via a water pipe 7, as soon as the shut-off valve 8 is opened as a function of a pulse emitted by the sensor 10.

Zur Erregung des mit einer Ankerwicklung ausgestatteten Absperrventils 8 in Abhängigkeit von den Impulsen des Sensors 10 dient ein Steuergerät 11, das über eine Signalleitung 12 mit dem Sensor 10 und eine weitere Signalleitung 13 mit dem Absperrventil 8 verbunden ist. Außerdem ist an das Steuergerät 11 zu dessen Versorgung mit elektrischer Energie sowie zur Versorgung der Ankerwicklung des Absperrventils 8 über eine Leitung 15 ein als aufladbarer Akkumulator oder als Kondensator ausgebildeter Energiespeicher 14 angeschlossen. Ein Betrieb ohne den Energiespeicher 14 ist aber auch möglich.A control unit 11, which is connected via a signal line 12 to the sensor 10 and a further signal line 13 to the shut-off valve 8, serves to excite the shut-off valve 8 equipped with an armature winding as a function of the pulses from the sensor 10. In addition, an energy store 14 designed as a rechargeable accumulator or as a capacitor is connected to the control unit 11 to supply it with electrical energy and to supply the armature winding of the shut-off valve 8 via a line 15. Operation without the energy store 14 is also possible.

Mittels des Steuergerätes 11 wird somit die Wasserzufuhr zu dem Wasserauslauf 9 gesteuert und diesem wird entsprechend der Einstellung des Mischventils 6 aus kaltem und warmem Wasser gemischtes Wasser, sobald durch den Sensor 10 das Steuergerät 11 aktiviert wird, zugeführt.By means of the control device 11, the water supply to the water outlet 9 is thus controlled and, according to the setting of the mixing valve 6, mixed water from cold and warm water is supplied as soon as the control device 11 is activated by the sensor 10.

Um den Energiespeicher 14 unabhängig von einem Stromnetz aufladen zu können, ist diesem ein Generator 31 zugeordnet, der über eine Stromleitung 34 an den Energiespeicher 14 angeschlossen ist. Der Generator 31 steht mit einer Turbine 21 in Triebverbindung, die um eine sich in Strömungsrichtung erstreckende Achse A durch das in der Wasserleitung 7 strömende Wasser rotierend antreibbar ist.In order to be able to charge the energy store 14 independently of a power grid, a generator 31 is assigned to it, which is connected to the energy store 14 via a power line 34. The generator 31 is in drive connection with a turbine 21, which can be driven in rotation about an axis A extending in the flow direction by the water flowing in the water line 7.

Die Turbine 21 sowie der Generator 31 sind, wie dies insbesondere der Figur 2 zu entnehmen ist, in einem als Stutzen ausgebildeten Rohrstück 16 eingebaut, das dazu eine kegelige Erweiterung 18 aufweist und mittels Gewinden 17 leicht in eine Leitung einzusetzen ist. Zur drehbaren Lagerung des Laufrades 22 der Turbine 21 ist das Rohrstück 16 mit einer ersten Zwischenwand 23 und einer zweiten Zwischenwand 24 ausgestattet, zwischen denen das Laufrad 22 zwischen Spitzen gelagert ist. Dazu ist in das Laufrad 22 ein Einsatzstück 41 eingesetzt, das auf der einen Seite mit einer Zentrierspitze 42 und auf der anderen Seite mit einer Zentrierbohrung 43 versehen ist, in die eine an der ersten Zwischenwand 23 angebrachte Zentrierspitze 44 eingreift. Und die Zentrierspitze 42 des Einsatzstückes 41 greift in eine Zentrierbohrung 46 eines in die zweite mit Strömungskanälen 24˝ versehene und somit gut durchströmbare Zwischenwand 24 eingesetzten Einsatzes 45 ein.The turbine 21 and the generator 31 are, as can be seen in particular in FIG. 2, installed in a pipe section 16 designed as a connection piece, which has a conical extension 18 for this purpose and by means of Thread 17 is easy to insert in a line. For the rotatable mounting of the impeller 22 of the turbine 21, the pipe section 16 is equipped with a first intermediate wall 23 and a second intermediate wall 24, between which the impeller 22 is mounted between tips. For this purpose, an insert 41 is inserted into the impeller 22, which is provided on one side with a centering tip 42 and on the other side with a centering hole 43 into which a centering tip 44 attached to the first intermediate wall 23 engages. And the centering tip 42 of the insert 41 engages in a centering bore 46 of an insert 45 which is inserted into the second intermediate wall 24 which is provided with flow channels 24˝ and can therefore be flowed through.

In die erste Zwischenwand 23 sind des weiteren im äusseren Durchmesserbereich mehrere Düsenöffnungen 25 eingearbeitet, und das Laufrad 22 der Turbine 21 ist mit diesen zugeordneten Leitschaufeln 26 bestückt, die somit bei einer Wasserentnahme von dem mit hoher Geschwindigkeit aus den Düsenöffnungen 25 austretenden Wasser beaufschlagt werden, so daß das Laufrad 22 der Turbine 21 mit hoher Drehzahl umläuft.A plurality of nozzle openings 25 are also incorporated into the first intermediate wall 23 in the outer diameter range, and the impeller 22 of the turbine 21 is equipped with these associated guide vanes 26, which are thus acted upon by the water emerging from the nozzle openings 25 at high speed when water is withdrawn. so that the impeller 22 of the turbine 21 rotates at high speed.

In einem axial abstehenden in eine Freisparung 20 des Rohrstückes 16 eingreifenden Ansatz 27 des Laufrades 22 sind ferner in axial gerichteten Nuten 28 Dauermagnete 32 eingesetzt, die mit in der Wandung 16′ des Rohrstückes 16 angeordnete Magnetspulen 33, die über die Stromleitung 34 mit dem Energiespeicher 14 verbunden sind, zusammenwirken, so daß bei Rotation des Laufrades 22 der Turbine 21 in den Magnetspulen 33 eine elektrische Leistung induziert wird. Die dem in der Wasserleitung 7 strömenden Wasser entnommene Energie wird somit ohne nennenswerte Verluste dem Energiespeicher 14 zugeführt.In an axially protruding recess 20 of the pipe section 16 engaging shoulder 27 of the impeller 22 permanent magnets 32 are also used in axially directed grooves 28, the magnet coils 33 arranged in the wall 16 'of the pipe section 16, which are connected via the power line 34 to the energy store 14 are connected, cooperate so that when the impeller 22 of the turbine 21 rotates, an electric power is induced in the magnetic coils 33. The energy taken from the water flowing in the water line 7 is thus supplied to the energy store 14 without any significant losses.

Die erste Zwischenwand 23 ist auf der angeströmten Seite mit einem strömungsgünstig geformten Ansatzstück 29 versehen, durch den somit ein Ringkanal 19 gebildet ist, über den das Wasser den Düsenöffnungen 25 zugeleitet wird. Und da auch das Laufrad 22 der Turbine 21 ein in Richtung der zweiten Zwischenwand 23 abstehendes Ansatzstück 30 aufweist, ist gewährleistet, daß die Strömungsverluste im Bereich der Turbine 21 und des Generators 31 gering gehalten werden.The first intermediate wall 23 is provided on the flow side with an aerodynamically shaped extension piece 29, through which an annular channel 19 is thus formed, via which the water is supplied to the nozzle openings 25. And since the impeller 22 of the turbine 21 also has an attachment piece 30 projecting in the direction of the second intermediate wall 23, it is ensured that the flow losses in the region of the turbine 21 and the generator 31 are kept low.

Bei dem Ausführungsbeispiel nach Figur 6 ist die Turbine 21′ radial innerhalb des Generators 31′ angeordnet. Dazu ist das mit Leitschaufeln 26′ bestückte Laufrad 22′ der Turbine 21′ zwischen zwei an den Zwischenwänden 23′ und 24′ angebrachten Zentrierspitzen 42′ und 44′ drehbar gehalten und trägt auf dem äußeren Umfang die Dauermagnete 32′ des Generators 31′, die bei Rotation des Laufrades 22′ mit den in die Wandung 16′ des Rohrstückes 16 eingesetzte Magnetspulen 33′ zusammenwirken, so daß in diesen wiederum elektrische Leistung induziert wird, die über die Stromleitung 34 dem Energiespeicher 14 oder unmittelbar dem Steuergerät 11 zuführbar ist.In the embodiment of Figure 6, the turbine 21 'is arranged radially within the generator 31'. For this purpose, the rotor 22 'equipped with guide vanes 22' of the turbine 21 'between two on the intermediate walls 23' and 24 'attached centering tips 42' and 44 'is rotatably supported and carries on the outer circumference the permanent magnets 32' of the generator 31 ', the with rotation of the impeller 22 'interact with the magnetic coils 33' inserted into the wall 16 'of the pipe section 16', so that in turn electrical power is induced in them, which can be fed via the power line 34 to the energy store 14 or directly to the control unit 11.
