Description

Die Erfindung bezieht sich auf Aufputz-Gehäuse für Spülarmaturen, nämlich elektronisch gesteuerte Urinalarmaturen, bestehend aus einem kastenartigen Formteil mit Abdeckhaube.The invention relates to surface-mounted housings for flushing fittings, namely electronically controlled urinal fittings, consisting of a box-like molded part with a cover.

Derartige Armaturen sind bereits bekannt (GB-A-2158475 und DE-OS 3414510). Dort werden Vorrichtungen zur elektronischen berührungslosen Steuerung einer Armatur, ganz allgemein solcher für den sanitären Bereich beschrieben, wie sie etwa für Waschtische, Urinale oder dergleichen benötigt werden, bei der mittels einer Sender-/Empfängereinrichtung die Öffnungs- und/oder Schließvorgänge für die Armatur durch die Betätigung beispielsweise eines Magnetventils von einer sich im Sende-/Empfangsbereich bewegenden Person ausgelöst wird. Es ist seit langem Wunsch und Ziel, bei entsprechend hohen Ansprüchen sanitäte Armaturen berührungsfrei betätigen zu können, wofür es zunächst von untergeordneter Bedeutung ist, ob zur Auslösung optoelektronische Sensoren oder geeignete andere Fühlorgane, die beispielsweise im Mikrowellenbereich arbeiten können, Anwendung finden. Letztlich dient jede der eingesetzten Sensortechniken der Betätigung eines Magnetventils zum Öffnen und Schließen des Wasserzulaufes zu der Armatur anstelle der manuell auszulösenden Selbstschlußarmaturen.Such fittings are already known (GB-A-2158475 and DE-OS 3414510). There devices for electronic contactless control of a fitting, generally described for the sanitary area, such as are required for washstands, urinals or the like, in which the opening and / or closing processes for the fitting are carried out by means of a transmitter / receiver device the actuation of a solenoid valve, for example, is triggered by a person moving in the transmission / reception area. It has long been a wish and goal, with correspondingly high demands on sanitary fittings To be able to operate without contact, for which it is of secondary importance whether optoelectronic sensors or suitable other sensing elements, which can work, for example, in the microwave range, are used for triggering. Ultimately, each of the sensor technologies used is used to actuate a solenoid valve to open and close the water supply to the fitting instead of the self-closing fittings to be triggered manually.

Der durch eine elektrische und/oder elektronische Steuerung zu betätigende Auslösemechanismus hatte jedoch bisher den Nachteil der Netzabhängigkeit, d.h. der Zuführung eines elektrischen Stromes über Netzanschlußleitungen zu der Steuereinheit.However, the trigger mechanism to be actuated by an electrical and / or electronic control has so far had the disadvantage of network dependency, i.e. the supply of an electrical current to the control unit via power cables.

Die grundlegende Idee, derartige Armaturen netzunabhängig durch Batteriebetrieb zu betätigen, ist in der DE-C-99973 beschrieben.The basic idea of operating such fittings independently of the mains by battery operation is described in DE-C-99973.

Erhöhte Anforderungen an die Hygiene und Auflagen im Gesundheitsbereich haben in letzter Zeit berührungslos betätigbare Armaturen erneut in den Vordergrund gerückt, wobei in einer Vielzahl von Anwendungsfällen die Notwendigkeit besteht, die bisher manuell betätigten Wasserarmaturen durch solche, die nur berührungslos ausgelöst werden können, zu ersetzen. Derartige Armaturen bieten darüber hinaus den großen Vorteil, daß ihre Steuerung praktisch für beliebige Programme vorgebbar ist, so unter anderem insbesondere für die Öffnungszeit des Magnetventils und damit die Dauer des Wasserlaufes.In recent times, increased demands on hygiene and requirements in the health sector have again brought to the fore faucets, although in a number of applications there is a need to replace the previously manually operated faucets with those that can only be triggered without contact. Such fittings also have the great advantage that their control can be practically specified for any program, in particular for the opening time of the solenoid valve and thus the duration of the water flow.

Neben der bereits erwähnten Schwierigkeit, elektrisch bzw. elektronisch gesteuerte Wasserarmaturen mit einer externen Stromversorgung verbinden zu müssen, besteht noch ein Nachteil darin, daß die gesamte Auslöse- und Steuereinheit in einem Kasten untergebracht werden muß, der, falls er nicht unter Putz installiert werden kann, über Putz zumindest den optischen Gesamteindruck der Einrichtung erheblich beeinträchtigt. Insbesondere Steuerungen für Urinalbecken wurden bisher oberhalb desselben bei Überputzanlagen als störend empfunden, da ihre Wartung, Anfälligkeit gegen äußere Störfaktoren und ähnliches zu unerfreulichen Begleiterscheinungen geführt hat und insofern derartige "Kästen" mehr als Fremdkörper als als homogene Ausrüstungsteile der Gesamtanlage empfunden wurden.In addition to the already mentioned difficulty of having to connect electrically or electronically controlled water fittings to an external power supply, there is also a disadvantage that the entire triggering and control unit has to be housed in a box which, if it cannot be installed under the plaster , at least the overall visual impression of the device is significantly impaired by plaster. Controls for urinal basins in particular have so far been perceived as annoying above plaster systems, since their maintenance, susceptibility to external interference factors and the like have led to unpleasant side effects and, in this respect, such "boxes" were perceived more as foreign bodies than as homogeneous equipment parts of the overall system.

Aus der US-A-1359892 ist eine Spülrohrverkleidung zwischen einem Wasserzufluß zum Spülbecken und einer Toilette bekannt, wobei das Spülbecken mittels einer das zur Toilette geführte Spülrohr abdeckenden Spülrohrverkleidung verlängert ist. Da diese Verkleidung teleskopartig ausgeführt ist, wird mit dieser Verkleidung unabhängig von gegebenen Installationsmaßen eine optische Einheit zwischen Spülbecken und Toilette ausgebildet.From US-A-1359892 a flush pipe cladding between a water inflow to the sink and a toilet is known, the sink being extended by means of a flush pipe cladding covering the flush pipe leading to the toilet. Since this cladding is telescopic, this cladding forms an optical unit between the sink and toilet regardless of the installation dimensions.

Hier setzt die vorliegende Erfindung ein, der die Aufgabe zugrunde liegt, eine elektronisch gesteuerte Urinalspülarmatur der eingangs genannten Art unter Verzicht auf jegliche Fremdstromversorgung so auszubilden, daß sie eine technisch und optisch in sich geschlossene Einheit bei den erhöhten Anforderungen an die Hygiene vorzugeben in der Lage ist, bei optimierter Installationsmöglichkeit.This is where the present invention begins, which is based on the object of designing an electronically controlled urinal flush valve of the type mentioned at the outset, without any external power supply, in such a way that it has a technically and optically self-contained unit with the increased demands on hygiene is able to specify, with optimized installation options.

Die Lösung dieser Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs erreicht.This object is achieved according to the invention by the characterizing features of the patent claim.

Dadurch, daß sich an eine Abdeckhaube eine Spülrohrverkleidung anschließt, die den gesamten Spülrohrbereich zwischen Urinal und elektronischer Steuereinheit bei in gewissen Grenzen frei vorgebbarer Abstandswahl vollständig übergreift, ergibt sich letztlich eine einzige Verkleidung, die mit dem Urinal selbst ein hygienisches Ganzes bildet, wobei sowohl die Installation der Gesamteinheit über eine an der Wand montierbare Platine als auch der Betriebsservice gegenüber bisher bekannter vergleichbarer Anlagen erheblich verbessert und erleichtert werden kann. Die Verschiebbarkeit der Spülrohrverkleidung in bezug auf die Abdeckhaube, das teleskopartige Ineinanderstecken einer oder mehrerer solcher Spülrohrverkleidungsteile optimiert die Montagemöglichkeiten auch unter schwierigsten Bedingungen, wobei die Arretierung einer einzigen Rohrschelle genügt, um das System in Stellung zu bringen. Für den Fall, daß man die Spülrohrverkleidung aus einem thermoplastischen Kunststoff herstellt und entlang der nicht sichtbaren Innenseite etwa rasterförmit Sollschnittstellen vorgibt, vereinfacht sich die Montage noch weiter und verbessert sich die jeweilige Anpaßmöglichkeit optimal.The fact that a flushing pipe cladding connects to a cover, which completely overlaps the entire flushing pipe area between the urinal and the electronic control unit with a freely selectable distance selection within certain limits, ultimately results in a single cladding that forms a hygienic whole with the urinal itself, both of which Installation of the entire unit via a wall-mountable board as well as the operational service compared to previously known comparable systems can be significantly improved and simplified. The displaceability of the flushing pipe cladding with respect to the cover, the telescopic insertion of one or more such flushing pipe cladding parts optimizes the installation options even under the most difficult conditions, the locking of a single pipe clamp being sufficient to bring the system into position. In the event that the rinsing pipe cladding is made of a thermoplastic and is provided along the invisible inner side, for example with grid-shaped target interfaces, the assembly is further simplified and the respective adaptability is optimally improved.

Die Fig. 1 zeigt das elektronische Wassersteuergerät mit optoelektronischem Sensor für eine Urinalarmatur im Längsschnitt. Die Armatur ist mit ihren einzelnen Steuerelementen im wesentlichen auf eine Wandplatine 10 aufgebracht, die vom einem Wasser-Anschlußstutzen 7 durchgriffen wird, wobei die Wandplatine 10 auf Putz einer nicht dargestellten Wand befestigt werden kann bzw. in den meisten Fällen der hier interessierenden sanitären Einrichtungen auf die Wandfliesen derselben aufgeschraubt wird. Wie dargestellt, umfaßt die elektronisch gesteuerte Urinalarmatur im wesentlichen ein dem Wasseranschlußstutzen 7 nachgeschaltetes und mit diesem über eine absperrbare Mengenregulierung 17 verbundenes Magnetventil 6, welches von der Elektronikeinheit 8 gesteuert wird, die ihrerseits ihre Energieversorgung von einer Batterie 9 erhält. Die Leistungsaufnahme der Elektronik 8 ist hierbei so ausgelegt, daß die innere Energieversorgung für einen normalen Dauerbetrieb von beispielsweise zwei Jahren ausreicht. Infolge der sehr geringen Leistungsaufnahme ist es selbstverständlich auch möglich, als innere Energieversorgung anstelle einer Batterie Solarzellen oder dergleichen Energiequellen für die Aufrechterhaltung des Armaturbetriebes in Anwendung zu bringen. Die Steuerelektronik ist im Ausführungsbeispiel so ausgelegt, daß zwei verschiedene über einen Wahlschalter einstellbare Wasser-Fliesprogramme eingestellt werden können, wobei jedoch eine beliebige Erweiterung der Programmzahl durchaus denkbar ist.Fig. 1 shows the electronic water control device with an optoelectronic sensor for a urinal fitting in longitudinal section. The valve is applied with its individual control elements essentially to a wall board 10, which is penetrated by a water connection piece 7, the wall board 10 can be attached to the plaster of a wall, not shown, or in most cases of the sanitary facilities of interest here the wall tiles of the same is screwed on. As shown, the electronically controlled urinal fitting essentially comprises a solenoid valve 6 connected downstream of the water connection stub 7 and connected to it via a lockable quantity control 17, which is controlled by the electronic unit 8, which in turn receives its energy supply from a battery 9. The power consumption of the electronics 8 is designed so that the internal energy supply is sufficient for normal continuous operation, for example two years. As a result of the very low power consumption, it is of course also possible to use solar cells or similar energy sources instead of a battery as internal energy supply for maintaining the valve operation. In the exemplary embodiment, the control electronics are designed so that two different water flow programs which can be set via a selector switch can be set, although any expansion of the number of programs is conceivable.

Die von der Batterie 9 über die Leitung 20 versorgte Elektronikeinheit 8 öffnet und schließt den Wasserzufluß für den Anschlußstutzen 7 über das Magnetventil 6 zu einem Winkelverbinder 19, der das Wasser zu dem Spülrohr 4 freigibt, welches seinerseits direkt in das nicht eingestellte Urinalbecken einmündet. Das wie die Wandplatine 10 direkt auf den Fliesen bzw. in einem genormten Abstand von diesen montierte Spülrohr 4 ist mit dem Winkelverbinder 19 über eine Überwurfmutter 18 lösbar befestigt.The electronics unit 8 supplied by the battery 9 via the line 20 opens and closes the water supply for the connecting piece 7 via the solenoid valve 6 to an angle connector 19, which releases the water to the flushing pipe 4, which in turn opens directly into the urinal basin not set. The flush pipe 4, which is mounted directly on the tiles or at a standardized distance from them, like the wall plate 10, is detachably fastened to the angle connector 19 by means of a union nut 18.

Die Gesamtheit der aufgezählten Einzelteile bis hin zum Spülrohransatz wird von einer Abdeckhaube 1 übergriffen, die aus einem Blechstanzteil, Metalldruckgußteil oder aus einem Kunststoffteil hergestellt sein kann, welches an der Wandplatine 10 über die oberen und unteren Zentrierstifte 12 und die Arretierschraube 13 lösbar angeschraubt ist. Bei der Montage ist eine exakt fluchtende Ausrichtung zwischen Anschlußstutzen 7 und dem Urinalbecken bzw. dem Einlauf des Spülrohrs 4 einmal über Verstellung des Winkelverbinders 19 selbst möglich, zum anderen aber auch über die Gewindeverbindung zwischen der Rohrschelle 3 und dem Gewindestutzen 5.The entirety of the items listed down to the rinsing pipe attachment is overlapped by a cover 1, which can be made from a stamped sheet metal part, a die-cast metal part or from a plastic part which is detachably screwed onto the wall plate 10 via the upper and lower centering pins 12 and the locking screw 13. When assembling is an exactly aligned Alignment between the connecting piece 7 and the urinal basin or the inlet of the flushing pipe 4 is possible once by adjusting the angle connector 19 itself, but also via the threaded connection between the pipe clamp 3 and the threaded connector 5.

Eine Öffnung 14 innerhalb der Abdeckhaube 1 gibt den optoelektronischen Sensor frei, der auf die Anwesenheit eines Benutzers in einem vorgegebenen Winkelbereich reagiert, jedoch erst nach einer eingestellten Sperrzeit aktivierbar ist. In Ruhestellung arbeitet die Einrichtung im sogenannten Standbybetrieb, also bei minimalem Energieverbrauch, und erst die Anwesenheit eines Benutzers schaltet auf Betriebsstellung um und bringt nach Verlassen des Einflußbereiches des optoelektronischen Reflexionssensors die Spülung zur Auslösung. Wird das Urinalbecken längere Zeit nicht benutzt, wodurch die Gefahr besteht, daß das Sperrwasser des Geruchsverschlusses austrocknen könnte, erfolgt über die Elektroniksteuerung eine automatische Zwangsauslösung des Wasserflusses, was beispielsweise alle 24 Stunden oder aber auch in einem anderen Zeitabschnitt sinnvoll sein kann. Bei Verwendung einer Batterie, wie im Ausführungsbeispiel dargestellt, wird nach Absinken des Batteriestromes unter einem voreingestellten Minimallevel das Magnetventil in die Schließstellung gebracht und die Einrichtung abgeschaltet.An opening 14 within the cover 1 releases the optoelectronic sensor, which reacts to the presence of a user in a predetermined angular range, but can only be activated after a set blocking time. In the idle position, the device operates in what is known as standby mode, that is to say with minimal energy consumption, and only when a user is present switches to the operating position and, after leaving the area of influence of the optoelectronic reflection sensor, triggers the purging. If the urinal basin is not used for a long time, which creates the risk that the sealing water of the odor trap could dry out, the electronic control automatically triggers the water flow, which can be useful, for example, every 24 hours or in another time period. When using a battery, as shown in the exemplary embodiment, the solenoid valve is brought into the closed position and the device is switched off after the battery current has dropped below a preset minimum level.

Bei der gezeigten Ausführungsform wird die Steuereinrichtung, die von der Abdeckhaube 1 übergriffen ist, oberhalb des Urinalbeckens befestigt, während das Urinalbecken selbst im Abstand hierzu senkrecht unterhalb der Abdeckhaube an der Fliesenwand festgemacht wird. Eine solche Einheit kann beispielsweise ein manuell betätigbares Selbstschlußventil leicht ersetzen bzw. an dessen Stelle montiert werden. Der optoelektronische Sensor innerhalb der Öffnung 14 der Abdeckhaube 1 läßt sich über die Schraubbefestigung 11 an der Abdeckhaube 1 befestigen und in geeigneter Weise einstellen. Zur Verkleidung des Spülrohres 4 zwischen der Abdeckhaube 1 und dem nicht dargestellten Urinalbecken dient die Spülrohrverkleidung 2, die in die Unterseite der Abdeckhaube 1 teleskopartig eingeschoben ist und sich hier im vollständig eingeschobenen Zustand vorzugsweise bis über die Hälfte der Höhenausdehnung der Abdeckhaube 1 in diese hinein erstreckt. Die Führung 21 dient der oberen Fixierung der Spülrohrverkleidung 2, während diese im unteren Bereich, d.h. unmittelbar am bzw. über den oberen Abschluß des Urinalbeckens mittels einer Rohrschelle 3, die das Spülrohr 4 übergreift, und einer Gewindestutzen/Schraubanordnung 5 fixiert wird. Eine Rutscheinlage 15 aus einem geeigneten Schaumstoff oder Dichtungsmaterial dient nicht nur dem sauberen Abschluß des Innenraumes der Abdeckhaube 1 gegenüber der Umgebung sondern gleichzeitig als eine Art Rutschsicherung bei der Montage, d.h. der jeweils erforderlichen Längeneinstellung der Spülrohrverkleidung 2 in bezug auf die Abdeckhaube 1. Auch über die Rohrschellenbefestigung kann eine mögliche Achsversetzung zwischen Spülrohr 4 und der Spülrohrverkleidung 2 auf einfache Weise bei der Montage ausgeglichen werden. Je nach Abstand zwischen Wasseranschluß und Oberkante des Urinalbeckens läßt sich auf diese Weise die Spülrohrverkleidung 2 mit Hilfe der Rohrschelle 3 auf dem Spülrohr 4 verschieben, wobei der obere Teil der Spülrohrverkleidung in der gezeigten teleskopartigen Form mehr oder weniger in die Abdeckhaube 1 hineinragt. Denkbar ist auch, daß die Spülrohrverkleidung 2 nicht nur aus einem einzigen Teilrohrstück besteht sondern aus mehreren wiederum in sich teleskopartig ineinandergeschobenen Einzelstücken. Darüber hinaus ist auch denkbar, daß die Gesamtheit der Vorrichtung so ausgelegt ist, daß die Spülrohrverkleidung 2 nicht von unten in die Abdeckhaube 1 geführt ist sondern beispielsweise seitlich, was zwar grundsätzlich möglich wäre, jedoch zu einer unerwünschten Einzelteilvielfalt führen müßte.In the embodiment shown, the control device is overlapped by the cover 1 is attached above the urinal basin, while the urinal basin itself is fastened vertically below the cover to the tiled wall. Such a unit can easily replace a manually operated self-closing valve, for example, or be installed in its place. The optoelectronic sensor within the opening 14 of the cover 1 can be fastened to the cover 1 via the screw fastening 11 and set in a suitable manner. To cover the flushing pipe 4 between the cover 1 and the urinal basin (not shown), the flushing pipe cover 2 is used, which is telescopically inserted into the underside of the cover 1 and here, when fully inserted, preferably extends up to over half the height of the cover 1 into it . The guide 21 serves for the upper fixing of the flushing pipe cladding 2, while this is fixed in the lower region, ie directly on or above the upper end of the urinal basin, by means of a pipe clamp 3 which overlaps the flushing pipe 4 and a threaded connector / screw arrangement 5. A slide insert 15 made of a suitable foam or sealing material not only serves to cleanly close the interior of the cover 1 from the environment, but at the same time serves as a kind of anti-slip device during assembly, ie the length adjustment of the flushing pipe cladding 2 required in relation to the cover 1. Also via the pipe clamp attachment can easily offset the axis between the flushing pipe 4 and the flushing pipe cladding 2 Be balanced during assembly. Depending on the distance between the water connection and the upper edge of the urinal basin, the flushing pipe cladding 2 can be moved in this way with the aid of the pipe clamp 3 on the flushing pipe 4, the upper part of the flushing pipe cladding projecting more or less into the cover 1 in the telescopic shape shown. It is also conceivable that the rinsing pipe cladding 2 does not only consist of a single partial pipe piece but also of several individual pieces which are telescopically pushed one inside the other. In addition, it is also conceivable that the entirety of the device is designed so that the rinsing pipe cladding 2 is not guided from below into the cover 1, but for example laterally, which would be possible in principle, but should lead to an undesirable variety of individual parts.

Zumindest die Fertigung der Spülrohrverkleidung aus einem geeigneten thermoplastischen Kunststoff kann insofern vorteilhaft sein, als hierdurch in die Innenwandung dieser Verkleidung Sollbruchstellen hineingebracht werden könnten, die bei unterschiedlichen Urinalbeckenwölbungen eine besonders optimale Anpassung des stirnseitigen Endbereiches der Spülrohrverkleidung an diese Form vereinfachen könnten, was gleichermaßen für Metalldruckguß gilt.At least the manufacture of the flushing pipe cladding from a suitable thermoplastic can be advantageous in that predetermined breaking points could be introduced into the inner wall of this cladding, which could simplify a particularly optimal adaptation of the front end area of the flushing pipe cladding to this shape in the case of different urinal pool curvatures, which is equally true for die-cast metal applies.

Die Fig. 2 und 3 zeigen die Zweiteiligkeit der Vorrichtung mit der Abdeckhaube 1 und ihren gerundeten Kantenführungen in Verbindung mit der hiergegen verschiebbaren Spülrohrverkleidung 2. Es wird auch deutlich, daß die Vorrichtung, die sich vorteilhaft für Umrüstzwecke, also für den Ersatz von bisher benutzten manuell zu betätigenden Selbstschlußventilen durch die elektronisch bewährungsfrei betätigbare Spüleinrichtung verwendet läßt, besonders vorteilhafte Möglichkeiten für die verschiedenen Montagemaße und die daran gestellten Anpassungserfordernisse vorgibt. Haube und Spülrohrverkleidung sind, wie aus den Fig. 2 und 3 verdeutlicht wird, so gestaltet, daß sie zusammen mit dem nicht dargestellten Urinalbecken ein einheitliches Ganzes bilden und sich in Form und Ausgestaltung zu einer auch optisch harmonischen Gesamtheit zusammenfügen. Es verbleiben ausschließlich spaltfreie problemlos zu reinigende glatte Flächen mit gerundeten Kantenführungen.2 and 3 show the two-part design of the device with the cover 1 and its rounded edge guides in connection with the flushing pipe cladding 2, which can be moved against it. It is also clear that the device, which can be used advantageously for retrofitting purposes, that is to say for the replacement of previously used manually operated self-closing valves by the flushing device which can be operated electronically without a prescription, specifies particularly advantageous possibilities for the various assembly dimensions and the adaptation requirements imposed thereon. The hood and flushing pipe cladding are, as is clear from FIGS. 2 and 3, designed in such a way that, together with the urinal basin (not shown), they form a unitary whole and form and form a harmonious whole. Only gap-free smooth surfaces with rounded edge guides that can be easily cleaned remain.
