Abstract

This invention concerns a process for actuating a physical/technical process, particularly in toilette facilities, which employs a sound sensor (M) with signal analysis which is located in close proximity to a liquid inlet (8). In a device for automatic cleaning of toilette seats (4), the sensor (M) is built in next to the flushing water inlet. The flushing noises are selected using a signal analysis circuit and cleaning of the seat (4) and evacuation of odors (G) via a ventilator (15) is only triggered if the flushing process has been clearly detected.

Description

Auslösung eines Reinigungs-, Lüftungs- und/oder Desinfektionsvorganges Triggering a cleaning, ventilation and / or disinfection process
Die vorliegende Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Anspruchs 1, sowie auf eine Vorrichtung zur Durchführung des Verfahrens und auf Anwendungen des Verfahrens .The present invention relates to a method according to the preamble of claim 1, and to an apparatus for performing the method and to applications of the method.
Bekannt ist eine selbstreinigende Toilette der Firma CWS International AG, Baar, welche einen, sich nach der Betäti- gung der Wasserspülung drehenden Toilettensitz aufweist. Die Auslösung der Drehung erfolgt in einer Version durch einen elektrischen Kontakt (Mikroschalter ; IR-Sensor) , welcher mit dem Betätigungshebel des Spülkastens verbunden ist. In der zweiten Version treibt das einlaufende Spülwas- ser, bzw. das Wasserleitungsnetz eine Turbine an, welche über einen Generator die Antriebεmotoren für die Toilettensitz -Reinigung, und -Desinfektion in Bewegung setzen.Known is a self-cleaning toilet from CWS International AG, Baar, which has a toilet seat that rotates after the water flush is actuated. In one version, the rotation is triggered by an electrical contact (microswitch; IR sensor) which is connected to the actuating lever of the cistern. In the second version, the incoming rinsing water or the water supply network drives a turbine, which sets the drive motors for the toilet seat cleaning and disinfection in motion via a generator.
Die bekannten Anordnungen haben sich in praxi grundsätzlich bewährt. Es hat sich aber gezeigt, daεs bei der Installa- tion und bei der Wartung Verantwortlichkeits- und Kompetenzprobleme entstehen, da die Installation nicht vom ordentlichen Sanitärmonteur betreut werden kann. Zusätzlich hat eine Verbindung der Steuer- und Antriebseinheit der Vorrichtung mit dem Spülkasten, aufgrund der sehr spezifi- sehen Anordnung weitere Nachteile, wie die von ungewollten Inbetriebnahmen, sowie eine systembedingte Störanfälligkeit.The known arrangements have basically proven themselves in practice. However, it has been shown that responsibility and competence problems arise during installation and maintenance, since the installation cannot be supervised by the ordinary sanitary fitter. In addition, a connection of the control and drive unit of the device to the cistern, due to the very specific arrangement, has further disadvantages, such as that of unwanted start-ups, and a system-related susceptibility to failure.
Es ist daher Aufgabe der Erfindung, einen physikalisch/- technischen Vorgang nur dann auszulösen, wenn dieser vom Benutzer oder Betreiber der Anlage gewollt ist. Auslösungen durch unvollständige Spül- und/oder EinlaufVorgänge sind ebenfalls zu eliminieren; der auszulösende Vorgang muss betriebssicher erfolgen. Es müssen auch mehrere benachbarte Einlauf- und/oder Spülvorgänge möglich sein, ohne dass diese einander beeinflussen.It is therefore an object of the invention to trigger a physical / technical process only when this is desired by the user or operator of the system. Triggered by incomplete rinsing and / or running-in processes also to be eliminated; the process to be triggered must be reliable. Several adjacent running-in and / or rinsing processes must also be possible without these influencing one another.
Ausserde soll im übrigen Gerätebereich kein Eingriff notwendig sein; die Verantwortung des Installations- und Wartungspersonals muss klar geregelt werden können, ohne dass diesem branchenfremde Aufgaben zufallen.In addition, no intervention should be necessary in the rest of the device area; The responsibility of the installation and maintenance personnel must be clearly regulated without being assigned to tasks that are not related to the industry.
Der Erfindungsgegenstand soll weitere nassraumbezogene An- Wendungen erlauben, die über die direkte Toilettenbenutzung hinausgehen.The subject of the invention is intended to permit further wet room-related applications that go beyond the direct use of the toilet.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst .This object is solved by the features of claim 1.
Die im Patentanspruch erwähnte Zuordnung eines Schallsen- sors im Nahbereich des Einlaufs einer Flüssigkeit bewirkt eine erste, räumliche und selektive Differenzierung beim Vorhandensein mehrerer gleicher oder ähnlicher Schallquellen.The assignment of a sound sensor mentioned in the patent claim in the vicinity of the inlet of a liquid brings about a first, spatial and selective differentiation in the presence of several identical or similar sound sources.
In nachfolgenden abhängigen Ansprüchen sind vorteilhafte Weiterbildungen des Erfindungsgegenstandes charakterisiert.Advantageous developments of the subject matter of the invention are characterized in the following dependent claims.
Das Verfahren nach Anspruch 2 ergibt eine verbesserte Unterscheidung der auslösenden Schallquelle von eventuell vorhandenen Störquellen.The method according to claim 2 results in an improved differentiation of the triggering sound source from any interference sources present.
Gemäss Anspruch 3 lässt sich durch eine Spektralanalyse die Dimensionierung des Filters und damit das Verfahren optimieren.According to claim 3, the dimensioning of the filter and thus the method can be optimized by a spectral analysis.
Zur Eichung des spezifischen Vorganges eignet sich vorteilhafterweise das Verfahren nach Anspruch 4. Nach der Eichung lässt sich die Aktivierung des physikalisch/technischen Gerätes nach Anspruch 5 reproduzierbar realisieren; dies erlaubt insbesondere unvollständige Spül- und/oder EinlaufVorgänge zu erkennen. Ebenfalls werden bei der Benutzung entstehende, andere EinlaufVorgänge sicher als solche erkannt, bzw. eine ungewollte Aktivierung des Gerätes kann nicht erfolgen.The method according to claim 4 is advantageously suitable for calibrating the specific process. After the calibration, the activation of the physical / technical device can be realized reproducibly; in particular, this allows incomplete flushing and / or running-in processes to be recognized. Other infeed processes occurring during use are also reliably recognized as such, or an unwanted activation of the device cannot take place.
Eine Bandfilterung gemäss der Vorrichtung nach Anspruch 6 ist besonders geeignet zur Überwachung des Einlaufs der Spülung in eine Toilettenschüssel.A band filter according to the device according to claim 6 is particularly suitable for monitoring the inflow of the flushing into a toilet bowl.
Hervorragend und wirtschaftlich zu realisieren ist aktives Bandfilter nach Anspruch 7.Active band filter according to claim 7 can be realized excellently and economically.
Die Vorrichtung nach Anspruch 8, aufgebaut aus vier handelsüblichen Operationsverstärkern ist sehr effizient.The device according to claim 8, constructed from four commercially available operational amplifiers, is very efficient.
Besonders vorteilhaft ist das in Anspruch 9 erwähnte Elek- tret-Mikrofon, aufgrund seiner selektiven Empfangscharakteristik und seiner robusten Ausgestaltung.The electric microphone mentioned in claim 9 is particularly advantageous due to its selective reception characteristic and its robust design.
Eine Anwendung nach Anspruch 10 verhindert eine unzeitige Auslösung eines Reinigungsvorgangs an einem Toilettensitz. Zusätzlich entsteht der grosse praktische Vorteil, dass die Reinigung und Desinfektion völlig autonom zur übrigen Sanitärinstallation ist und somit bei der Montage und auch beim Unterhalt der Geräte eine klare fachgebietliche Trennung zwischen Sanitärinstallateur und Apparatelieferant bzw. Ap- paratetechniker gewährleistet ist.An application according to claim 10 prevents an untimely triggering of a cleaning process on a toilet seat. In addition, there is the great practical advantage that cleaning and disinfection is completely autonomous from the rest of the sanitary installation and thus a clear technical separation between the sanitary installer and the appliance supplier or appliance technician is guaranteed during assembly and maintenance of the devices.
Die Steuerung der Absaugvorrichtung in einer Toilette und/- oder im Toilettenraum nach Anspruch 11 lässt eine energetisch günstige Lüftung zu und verhindert unangenehme Zugerscheinungen. Ebenfalls können geruchsbindende Vorgänge ausgelöst werden, Anspruch 12, wenn diese nötig sind, d.h. unzweckmässige und materialverbrauchende, regelmässige Auslösungen im Zusammenhang mit den ordentlichen Türbetätigungen, können elimi- niert werden.The control of the suction device in a toilet and / or in the toilet room according to claim 11 allows energy-efficient ventilation and prevents unpleasant drafts. Odor-binding processes can also be triggered, claim 12, if these are necessary, ie inappropriate and material-consuming, regular triggering in connection with the normal door operations can be eliminated.
Anwendungen gemäss Anspruch 13 können zur Reduktion des Wasserverbrauchs genutzt werden; zudem erlauben sie den Einbezug weiterer Reinigungsvorgänge in Zusammenhang mit der Benutzung, beispielsweise einer öffentlichen Toilette.Applications according to claim 13 can be used to reduce water consumption; in addition, they allow the inclusion of further cleaning processes in connection with the use, for example a public toilet.
Nach Anspruch 14 lassen sich zusätzlich vorhandene Geräte sperren und/oder aktivieren, um beispielsweise deren Benutzung nur in Verbindung mit einer kontrollierten Toilettenbenutzung zu erlauben.According to claim 14, existing devices can also be blocked and / or activated, for example to allow their use only in connection with a controlled use of the toilet.
Anhand von Zeichnungen werden nachfolgend Ausführungsbei- spiele des Erfindungsgegenstandes näher beschrieben.Exemplary embodiments of the subject matter of the invention are described in more detail below with the aid of drawings.

Fig. 4 eine vereinfachte Darstellung einer Toilette mit Reinigungs- und Desinfiziervorrichtung und einer gezielten Absaugung von unangenehmen Gerüchen am Ort ihres entstehens. In Figur 1 ist ein handelsüblicher Vierfachverstärker mit A100 bezeichnet. Dieser besteht aus hintereinander geschalteten Operationsverstärkern AI bis A4, welche entsprechend ihrer Funktion in üblicher Weise geschaltet bzw. rückgekop- pelt sind.Fig. 4 is a simplified representation of a toilet with a cleaning and disinfecting device and a targeted suction of unpleasant smells at the place of their creation. A commercially available quadruple amplifier is designated A100 in FIG. This consists of operational amplifiers AI to A4 connected in series, which are switched or fed back in the usual way according to their function.
Die Verstärkerkette besteht somit aus einem einzigen vierstufigen Breitband-Operationsverstärker A100; bewährt hat sich ein Typ LM 837N (National Semiconductors, USA) .The amplifier chain thus consists of a single four-stage broadband operational amplifier A100; a type LM 837N (National Semiconductors, USA) has proven itself.
Diesem Operationsverstärker A100 wird ein Eingangssignal e, das frequenz-selektive Ausgangssignal eines Schallsensors, zugeführt; das verstärkte und demodulierte Steuersignal ist mit S bezeichnet. Die charakteristische Erdung des Verstärkers A100 ist aus elektrischen und sicherheitstechnischen Gründen notwendig.An input signal e, the frequency-selective output signal of a sound sensor, is fed to this operational amplifier A100; the amplified and demodulated control signal is denoted by S. The characteristic grounding of the A100 amplifier is necessary for electrical and safety reasons.
Wesentlich ist, dass die Charakteristik der spezifischen Schallquelle reproduzierbar gespeichert ist. Diesem Zweck dient ein Eichprogra , welches in Fig. 2 aufgezeichnet ist.It is essential that the characteristics of the specific sound source are stored reproducibly. A calibration program, which is recorded in FIG. 2, serves this purpose.
Ein Speicherwert ml ist in einem nichtflüchtigen Speicher (EEprom) als Initialwert vorgegeben und zu einem Entschei- dungsknoten Dl geführt und auf dessen Plausibilität geprüft. Am einen Ausgang des Entscheidungsknotens Dl befindet sich ein Grundwert-Speicher Ml, der den geprüften Wert ml als Initialwert speichert; am zweiten Ausgang von Dl ist ein Funktionselement Fl geschaltet, welches als Status-An- zeige (LED) ausgebildet ist. Nachgeschaltet ist ein weiterer Entscheidungsknoten D2 , welcher über eine Rückführung die Tastenstellung, den Einschaltzustand, überprüft. Der Ausgang von D2 ist zu einem Funktionselement F2 , einem Elektret-Mikrofon geführt, an dessen Ausgang ein weiterer Entscheidungsknoten D3 , die Höhe des Signalpegels überprüft und über F3 eine Verzögerungszeit vom 200 ms (Totzeit) schaltet. Nach diesen 200 ms tritt wiederum ein Funktionselement F4, das Elektret-Mikrofon in Funktion. Der nachge- schaltete Knoten D4 überprüft den Signalpegel erneut; ein Element F5 schaltet eine Verzögerungszeit von 500 ms. Mit einem Element F6 erfolgen anschliessend 10 Messungen, aus denen ein Mittelwert gebildet wird. Dieser wird einem Ele- ment F7 zugeführt und im Element F8 , der LED-Anzeige bestätigt .A storage value ml is specified in a non-volatile memory (EEprom) as the initial value and is led to a decision node D1 and checked for its plausibility. At an output of the decision node Dl there is a basic value memory Ml, which stores the checked value ml as the initial value; At the second output of DI, a functional element F1 is connected, which is designed as a status display (LED). A further decision node D2 is connected downstream, which checks the key position, the switch-on state, via feedback. The output of D2 leads to a functional element F2, an electret microphone, at the output of which another decision node D3 checks the level of the signal level and switches a delay time of 200 ms (dead time) via F3. After these 200 ms, a functional element F4, the electret microphone, comes into operation again. The follow-up switched node D4 checks the signal level again; an element F5 switches a delay time of 500 ms. An element F6 is then used for 10 measurements, from which an average is formed. This is fed to an element F7 and confirmed in element F8, the LED display.
Ein weiterer Entscheidungsknoten D5 prüft, ob der Vorgang genügend oft, im vorliegendem Fall ein Spülvorgang dreimal vollständig wiederholt wurde und zwischen den einzelnen Vorgängen eine Wartezeit von 20 s eingehalten wurde; Diese Zeitspanne entspricht der minimalen Füllzeit des Spülkastens. Die Prüfung erfolgt über das Element F9 , zusammen mit den Entscheidungsknoten D4 und D3. Verläuft die Prüfung positiv, so wird aus den drei vorherigen Vorgängen ein einziger Mittelwert gebildet, durch F10.Another decision node D5 checks whether the process has been repeated enough times, in the present case a rinsing process has been repeated three times, and whether a waiting time of 20 s has been observed between the individual processes; This time period corresponds to the minimum filling time of the cistern. The test is carried out via element F9, together with decision nodes D4 and D3. If the test is positive, F10 is used to form a single mean from the three previous processes.
Die nachfolgenden Funktionselemente Fll bis F13 haben die Aufgaben einen Sicherheitswert zu addieren, den resultierenden Wert zu speichern, wiederum im EEprom, und die Signalanzeige zu setzen.The following functional elements Fll to F13 have the tasks of adding a safety value, storing the resulting value, again in the EEprom, and setting the signal display.
Sämtliche resultierenden Werte sind Bestandteil der neuen Grundeinstellung M2.All resulting values are part of the new basic setting M2.
Die Auslösung eines Reinigungszyklus erfolgt nach Fig. 3 durch die dort dargestellte Mikrofon Signal-Analyse. Hier wird von einem an sich bekannten Steuerprogramm (Haupt- programm) das Signal el eingelesen; F14 schaltet das Mikrofon zu, D6 überprüft dessen Signalpegel anhand des vorgegebenen und durch den Eichvorgang ermittelten einzigen Mittelwertes, auf seinen Minimalpegel.A cleaning cycle is triggered according to FIG. 3 by the microphone signal analysis shown there. The signal el is read in here by a control program (main program) known per se; F14 switches on the microphone, D6 checks its signal level for its minimum level on the basis of the predetermined single mean value determined by the calibration process.
Beim unterschreiten des Minimalpegels, wird ein Signal e2 generiert, welches das ablaufende Programm wieder auf das Hauptprogramm zurücksetzt. Die nachgeschalteten Elemente F15 und F] 6 bewirken eine Verzögerung von 200 ms und ein erneutes Zuschalten des Mikrofons. Der Entscheidungsknoten D7 prüft zusammen mit D6 den zulässigen Pegelwert nochmals. Die anschliessenden Funktionselemente F17 und F18 üben eine Zählfunktion aus; sie dienen zusammen mit einem weiteren Verzögerungselement F20 welches auf 50 ms eingestellt ist, eine zeitliche Überprüfung des Signalflusses auf seine Kohärenz, wobei D8 das Nullsetzen der Zähler kontrolliert und ein entsprechendes Steuersignal S abgibt, wenn das Mikrofon, d.h. das Element F19 keine neue Signale liefert.If the minimum level is undershot, a signal e2 is generated which resets the running program back to the main program. The downstream elements F15 and F] 6 cause a delay of 200 ms and the microphone is switched on again. The decision node D7 checks together with D6 the permissible level value again. The subsequent function elements F17 and F18 perform a counting function; together with a further delay element F20, which is set to 50 ms, they serve to check the coherence of the signal flow over time, whereby D8 controls the zeroing of the counters and emits a corresponding control signal S if the microphone, ie element F19, does not deliver any new signals .
Das Steuersignal S startet das Funktionselement F100 mit seinem Aktuatoren wie Antriebsmotoren, Sprühventilen etc.The control signal S starts the functional element F100 with its actuators such as drive motors, spray valves etc.

Ein entsprechender Auslaufstutzen 10, ist in Teilschnittdarstellung zu sehen; daneben befindet sich eine Bohrung 9 , in welcher etwas zurückversetzt, ein Elektret-Mikrofon M angeordnet ist. Dieses liefert ein Ausgangsignal e das zu einer hier nicht näher dargestellten Klemme geführt ist.Inside the basin 6 there is a water inlet 8 for the notoriously known rinsing process. A corresponding outlet nozzle 10 can be seen in a partial sectional view; next to it there is a bore 9, in which an electret microphone M is arranged somewhat recessed. This provides an output signal e which is led to a terminal not shown here.
Der Stutzen 10 ist in üblicher Weise mit einem Wasserzu- fluss 11 verbunden, der zu einem Spülkasten - mit H20 bezeichnet - führt. Quer in den Wasserzufluss 11 führt ein Absaugrohr 12, welches durch einen Ventilator 15 Gase G zu einer Abluft-Düse 16 transportiert.The nozzle 10 is connected in the usual way to a water inflow 11, which leads to a cistern - designated H 2 0 -. Introduces transversely into the water inflow 11 Suction pipe 12, which transports gases G to an exhaust air nozzle 16 through a fan 15.
Ist das Mikrofon M entsprechend den Bedingungen nach dem Program der Fig. 3 mit Schall, durch den EinlaufVorgang der Spülung, beaufschlagt worden, so wird ein Steuersignal S generiert, welches eine Reinigungs- und Desinfektionsstation 14 ausfährt und gleichzeitig über hier nicht dargestellte Antriebsmotoren den Klosett-Sitz 4 in Pfeilrichtung r dreht .If the microphone M has been subjected to sound by the running-in process of the flushing in accordance with the conditions according to the program of FIG. 3, a control signal S is generated which extends a cleaning and disinfection station 14 and at the same time drives the toilet via drive motors (not shown here) - Seat 4 rotates in the direction of the arrow r.
Am oberen Teil des Deckels der Reinigungseinheit 2 befindet sich die LED-Statusanzeige 13. Zur Speisung dient ein üblicher Netzanschluss 17.The LED status display 13 is located on the upper part of the cover of the cleaning unit 2. A conventional mains connection 17 is used for the supply.
Sämtliche verwendeten Komponenten sind handelsüblich; die Programmierung des EEproms erfolgte ebenfalls konventio- nell, das verwendete Elektretmikrofon (Panasonic, JP; TypWM 56A103) weist eine untere Grenzfrequenz von 2 KHz auf, so dass wesentlich Umgebungsgeräusche gar nicht ausgewertet werden.All components used are commercially available; The EEprom was also programmed conventionally; the electret microphone used (Panasonic, JP; type WM 56A103) has a lower cut-off frequency of 2 KHz, so that ambient noise is not evaluated at all.
An Stelle der in Fig. 4 dargestellten Ansteuerung eines Ventilators 15, zur Absaugung von unangenehmen Gerüchen, hat sich auch eine direkte Zuschaltung eines Abluftventils (Danfoε, DK; Typen EVISIT) mit einer Einleitung in die Gebäudeentlüftung bewährt. Zur Vermeidung von störenden Zugerscheinungen und zur Energieeinsparung ist die Lüftungs- dauer, nach jeder Betätigung der Klosettspülung, auf 5 Min. begrenzt .Instead of the control of a fan 15 shown in FIG. 4 for the extraction of unpleasant smells, a direct connection of an exhaust air valve (Danfoε, DK; types EVISIT) with an introduction into the building ventilation has also proven itself. To avoid disruptive drafts and to save energy, the ventilation time is limited to 5 minutes after each flushing operation.
Der Erfindungsgegenstand eignet sich zur gezielten Aktivierung von zahlreichen Vorgängen, welche in Zusammenhang mit der Benutzung von Toiletten und Waschräumen zweckmässig sind. Denkbar ist u.a. auch die Auslösung von periodischen ReinigungsVorgängen, beispielsweise der Flutung von Toiletten nach einer gewissen Anzahl von Spülvorgängen, etc. The object of the invention is suitable for the targeted activation of numerous processes which are expedient in connection with the use of toilets and washrooms. It is conceivable also the triggering of periodic cleaning processes, e.g. the flooding of toilets after a certain number of flushing processes, etc.
