Die in Fig. 1 gezeigte berührungslos gesteuerte Wasserauslaufarmatur wird von einem Armaturenkörper 1 gebildet, an dem einerseits stirnseitig an Wassereinlaßöffnungen Zuflußleitungen 10 angeschlossen sind, und an dem am anderen Endbereich eine Auslaßöffnung 11 für die Abgabe eines Wasserstrahls angeordnet ist. Im Bereich der Zuflußleitungen 10 ist außerdem stirnseitig eine Befestigungseinrichtung 14 in bekannter Weise angeordnet, die zur Halterung der Wasserarmatur an einem in der Zeichnung nicht dargestellten Wasch- oder Spültisch dient.
Im Armaturenkörper 1 ist ein Aufnahmeraum 12 ausgebildet, in dem eine Steuerung 2, die in einem starren Gehäuse 20 angeordnet ist, vorgesehen ist. Die Steuerung 2 enthält hierbei einen Annäherungsschalter, mit dem ein bestimmter Detektionsbereich überwacht wird. Gelangt ein Benutzer in den Detektionsbereich, so wird von der Steuerung 2 ein im Armaturenkörper 1 vorgesehenes Elektromagnetventil (in der Zeichnung nicht dargestellt) geöffnet, und ein Wasserstrahl kann durch die Auslaßöffnung 11 austreten. In dem Gehäuse 20 der Steuerung 2 sind daher zwei axial zueinander versetzt angeordnete radial vorstehende Fenster 22 ausgebildet, wobei beispielsweise durch ein erstes Fenster 22 Infrarotlichtstrahlen ausgesandt und von einem zweiten Fenster 22 die vom Benutzer reflektierten Infrarotlichtstrahlen aufgenommen werden, wonach dann in der Steuerung 2 entsprechende Steuervorgänge erfolgen.The contactlessly controlled water outlet fitting shown in FIG. 1 is formed by a fitting body 1, to which on the one hand inlet lines 10 are connected at the front to water inlet openings, and on which an outlet opening 11 for dispensing a water jet is arranged at the other end region. In the area of the inflow lines 10, a fastening device 14 is also arranged on the end in a known manner, which is used to hold the water fitting on a washstand or sink, not shown in the drawing.
In the valve body 1, a receiving space 12 is formed, in which a controller 2, which is arranged in a rigid housing 20, is provided. The controller 2 in this case contains a proximity switch with which a specific detection range is monitored. If a user comes into the detection area, the control 2 opens an electromagnetic valve (not shown in the drawing) provided in the valve body 1, and a water jet can exit through the outlet opening 11. In the housing 20 of the controller 2, therefore, two radially projecting windows 22, which are arranged axially offset from one another, are formed, with infrared light rays being emitted, for example, through a first window 22 and the infrared light rays reflected by the user being received by a second window 22, after which the controller 2 then corresponds Tax operations take place.

Der Aufnahmeraum 12 ist, wie es insbesondere aus Fig. 4 ersichtlich ist, im Querschnitt etwa kreissegmentförmig ausgebildet. Entsprechend kreissegmentförmig im Querschnitt ist auch das Gehäuse 20 der Steuerung 2 ausgebildet, wie es insbesondere aus Fig. 5 zu entnehmen ist. Außerdem ist im Bereich der zylindrischen Wandung des Gehäuses 20 eine elastische Zwischenlage 4 aus Flachmaterial angeordnet und mit Abstand um die Fenster 22 angeordnet. Der Abstand zu den Fenstern 22 wird jeweils von einem ringförmigen erhabenen Bereich 23 bestimmt, wobei die Zwischenlage 4 mit ihren Öffnungen am Außenrand der Bereiche 23 anliegt. Die Bereiche 23 bilden mit ihrer Stirnseite die Anlagefläche des Gehäuses 20 an der Wandung des Aufnahmeraums 12, wobei die Fenster 22 radial in Öffnungen 13 am Armaturenkörper 1 hineinfassen. Die Dicke der Zwischenlage 4 ist im entspannten Zustand größer als die Dicke der Bereiche 23.The receiving space 12 is, as is particularly the case in FIG. 4 can be seen, approximately in the form of a segment of a circle in cross section educated. Correspondingly in the form of a circular segment in cross section the housing 20 of the controller 2 is also formed, as can be seen in particular from FIG. 5 is. It is also in the area of the cylindrical wall of the housing 20 from an elastic intermediate layer 4 Flat material arranged and spaced around the windows 22 arranged. The distance to the windows 22 is in each case determined by an annular raised area 23, the intermediate layer 4 with its openings on The outer edge of the areas 23 abuts. Form the areas 23 with its end face the contact surface of the housing 20 on the wall of the receiving space 12, the windows 22 radially in openings 13 on the valve body 1 reach inside. The thickness of the intermediate layer 4 is relaxed State greater than the thickness of the areas 23.

Die Steuerung 2 ist in der Stecklage von einem Keilelement 3 in dem Aufnahmeraum 12 verspannt. Das Keilelement 3 wird dabei von zwei parallel zueinander angeordneten Keilschienen 30 gebildet, die über einen Quersteg 32 einstückig miteinander verbunden sind, wie es insbesondere aus Fig. 6 der Zeichnung zu entnehmen ist. Die Keilschienen 30 weisen hierbei einen Keilwinkel 31 von 1° bis 5°, vorzugsweise 2°, auf. An der einen Stirnseite der Keilschienen 30 ist jeweils eine Verzahnung 33 ausgebildet. Die Verzahnung 33 ist sägezahnartig ausgebildet, wie es insbesondere aus Fig. 3 zu entnehmen ist und sowohl an der einen Stirnseite der Keilschienen 30 als auch am Gehäuse 20 ausgebildet. Die einzelnen Zähne der Verzahnung 33 weisen eine Zahnhöhe von etwa 0,2 mm und einen Zahnabstand von etwa 1 mm auf, wobei das Zahnprofil etwa ein rechtwinkliges Dreieck bildet. Das Gehäuse 20 der Steuerung 2 und das Keilelement 3 sind im Spritzgießverfahren aus Kunststoff hergestellt. Die elastische Zwischenlage 4 ist aus einem Elastomer gebildet.
Die Einmontage der Steuerung 2 in den Armaturenkörper 1 kann in folgender Weise erfolgen:
Zunächst wird an der in Fig. 5 gezeigten Steuerung 2, die gekapselt in dem Gehäuse 20 angeordnet ist, die Zwischenlage 4 über die Bereiche 23 übergestreift. Sodann wird die komplette Baueinheit axial in den an der unteren Stirnseite des Armaturenkörpers 1 geöffnet ausgebildeten Aufnahmeraum 12 eingeschoben und danach radial mit den Fenstern 22 in die Öffnungen 13 im Armaturenkörper 1 eingesteckt. Hierbei gelangt die Zwischenlage 4 an der Wandung des Aufnahmeraums 12 zur Anlage. Mit dem Einfassen der Fenster 22 in die Öffnungen 13 ist das Gehäuse 20 in dem Aufnahmeraum 12 axial gehalten. Nunmehr kann das Keilelement 3 axial in den Aufnahmeraum 12 eingeschoben werden. Hierbei liegen die glatten Stirnseiten der Keilschienen 30 an Seitenwänden 120 des Aufnahmeraums auf. Die mit der Verzahnung 33 versehenen Stirnseiten der Keilschienen 30 fassen andererseits in Nuten 21 des Gehäuses 20 ein, die entsprechend dem Keilelement 3 geneigt zur Stirnfläche der Bereiche 23 ausgebildet sind und eine entsprechende Verzahnung 33 aufweisen. Die Keilschienen 30 sind hierbei so bemessen, daß das Keilelement 3 völlig in den Aufnahmeraum 12 eingetrieben werden kann, wobei in der Eintriebstellung das Gehäuse 20 mit den Stirnflächen der ringförmigen Bereiche 23 an der Wandung des Armaturenkörpers 1 anliegt. Die elastische Zwischenlage 4 ist hierbei entsprechend zusammengedrückt und bildet eine zuverlässige Abdichtung im Bereich der Fenster. Die Verzahnung 33 ist hierbei so ausgebildet bzw. die Zahnflanken der einzelnen Zähne so angeordnet, daß nach einem Einfügen der Steuerung 2 mit dem Keilelement 3 das Keilelement nur mit einer Zerstörung desselben aus dem Aufnahmeraum 12 wieder entfernt werden kann.The controller 2 is clamped in the plug-in position by a wedge element 3 in the receiving space 12. The wedge element 3 is formed by two wedge rails 30 arranged parallel to one another, which are integrally connected to one another via a transverse web 32, as can be seen in particular from FIG. 6 of the drawing. The wedge rails 30 here have a wedge angle 31 of 1 ° to 5 °, preferably 2 °. A toothing 33 is formed on one end of the wedge rails 30. The toothing 33 is sawtooth-like, as can be seen in particular from FIG. 3, and is formed both on one end face of the wedge rails 30 and on the housing 20. The individual teeth of the toothing 33 have a tooth height of approximately 0.2 mm and a tooth spacing of approximately 1 mm, the tooth profile forming approximately a right-angled triangle. The housing 20 of the controller 2 and the wedge element 3 are made of plastic by injection molding. The elastic intermediate layer 4 is formed from an elastomer.
The control 2 can be installed in the valve body 1 in the following way:
First, on the controller 2 shown in FIG. 5, which is encapsulated in the housing 20, the intermediate layer 4 is slipped over the areas 23. The complete assembly is then inserted axially into the receiving space 12, which is open on the lower end face of the valve body 1, and then inserted radially with the windows 22 into the openings 13 in the valve body 1. Here, the intermediate layer 4 comes to rest against the wall of the receiving space 12. With the bordering of the windows 22 in the openings 13, the housing 20 is held axially in the receiving space 12. Now the wedge element 3 can be inserted axially into the receiving space 12. Here, the smooth end faces of the wedge rails 30 rest on side walls 120 of the receiving space. The end faces of the wedge rails 30 provided with the toothing 33, on the other hand, engage in grooves 21 of the housing 20, which are designed to be inclined to the end face of the regions 23 in accordance with the wedge element 3 and have a corresponding toothing 33. The wedge rails 30 are dimensioned so that the wedge element 3 can be driven completely into the receiving space 12, the housing 20 with the end faces of the annular regions 23 abutting the wall of the valve body 1 in the drive-in position. The elastic intermediate layer 4 is compressed accordingly and forms a reliable seal in the area of the windows. The toothing 33 is designed in this case or the tooth flanks of the individual teeth are arranged in such a way that, after inserting the control 2 with the wedge element 3, the wedge element can only be removed from the receiving space 12 once the latter has been destroyed.

Alternativ kann die Verzahnung 33 so ausgebildet werden, daß die Zahnflanken auch ein zerstörungsfreies Lösen des Keilelements 3 aus seiner Stecklage ermöglichen. Hierbei kann die Verzahnung vorteilhaft so ausgebildet sein, daß für die Lösung des Keilelements eine erhöhte Krafteinlenkung erforderlich ist. Auch kann die Verzahnung insgesamt wellenförmig verrundet, beispielsweise in der Form einer flachen Sinuskurve, ausgebildet sein, wobei aber auch mit einer derartigen Verzahnung sichergestellt sein muß, daß einerseits ein Eintreiben und Lösen des Keilelements erfolgen kann, andererseits aber eine sichere Verrastung in der Stecklage gewährleistet ist.Alternatively, the toothing 33 can be designed that the tooth flanks also a non-destructive loosening enable the wedge element 3 from its inserted position. The toothing can advantageously be designed in this way be that for the solution of the wedge element increased force is required. It can also Teeth rounded in a wave shape, for example in the form of a flat sine curve be, but also with such a toothing it must be ensured that, on the one hand, a collection and releasing the wedge element can take place, on the other hand but ensures a secure locking in the mated position is.
