- the invention has for its object to provide a toilet equipment with the annoying odors can be suppressed very effective and reliable, the risk of ingress of rinse water is avoided in the deodorizing.
- Usual toilet bowls have at the upper edge of a hidden annular channel with outlet openings for the rinse water.
- the annular channel may also have a complete or partially open flushing channel instead of the pierced outlet openings to have.
- This channel opens at the rear end of the toilet bowl a Spülwasserstutzen, in which the flushing pipe is inserted with a sealing sleeve.
- the suction channels are attached in this embodiment of the invention to the annular channel. The air is sucked out of the interior of the toilet bowl and passed through the DOM via the annular channel and the two outgoing exhaust ducts, which are connected to the suction pipe of the DOM.
- suction channels are suitably formed in the ceramic of the toilet bowl and have at its rear end on the top openings for connection to the suction pipe of the deodorizing device.
- this connection is made via a flexible hose piece.
- the Spülwasserstutzen has constrictions at the points where the Spippowasserstutzen is connected to the annular channel.
- the constrictions are dimensioned such that the pressure drop of the flushing water flow substantially takes place in them and the flushing water is distributed after the constrictions substantially without pressure in the annular channel and exits through the openings in the toilet bowl.
- the suction channels branch off after the constrictions of the annular channel, so that the rinse water is not pressed into the suction channels.
- the deodorizing apparatus generally has a fan means for sucking the air from the inside of the toilet bowl and a deodorizing means for removing odor molecules.
- the fan draws in air via the intake pipe and delivers it to the deodorizing device, which may be an activated carbon filter or an ionizing device.
- the deodorizing device further includes a switching device by which the fan device is turned on when using the toilet. Electricity is thereby only consumed while using the toilet.
- the switching device may be a switch which is arranged under the seat board and closes a circuit when depressing the seat board.
- known devices such as capacitive sensors or infrared sensors can be used to detect the presence of a person and thus the use of the toilet.
- the switching means may also be a piezoelectric pressure transducer integrated with a washer disposed between the stationary hinge part of the seat board and the top of the WC bowl. As the user sits down on the seat board, pressure is applied to the piezoelectric transducer to change its resistance, and that is reduced. The current flowing therethrough is received as a use signal from the controller.
- Another possibility is to store one of the two fastening screws of the stationary hinge part of the seat board displaceable in the opening provided for the attachment of this screw opening in the top of the toilet bowl and support it by a spring element.
- the fixing screw is pressed down slightly against the resilient support when a person sits down on the seat board. This displacement of the fastening screw is then used to actuate a switch mounted on the underside of the edge of the toilet bowl, which constitutes the switching device.
- This embodiment can be realized in that the fastening screw is secured in an inner sleeve, which in turn is mounted vertically displaceable in an outer sleeve. Both sleeves have at their upper end a disc-shaped flange and between the two flanges an elastic ring is inserted.
- the inner sleeve protrudes at the lower end over the outer sleeve, and at its lower end an actuating arm is fixed, which presses in the normal state from below against a micro-switch, which at the lower end of the outer sleeve is fixed.
- the microswitch is designed to close a circuit thereby activating the control of the deodorizing device.
- the deodorizing device preferably further comprises an odor sensor which provides an output signal depending on existing oxidizable odor molecules or certain gas molecules.
- VOC Volatile Organic Compound
- a semiconductor tin oxide sensor which detects oxidizable gas components in the air.
- sensors are well known and are available, for example, from FIS Inc., 2-5-26, Hachizuka, Ikeda, Osaka, 563-0024 Japan. It is suitable, e.g. the FIS gas sensor SB-AQ1A.
- H 2 sensor is also suitable.
- hydrogen is an odorless gas, it can be used as a guide gas, since it is always formed in human digestion, while the other gas constituents, such as methane or H 2 S depending on the ingested food to a greater or lesser extent or not formed .
- hydrogen has the advantage that it is not used in perfumes and similar cosmetics, so that a false response of the sensor to such cosmetics is prevented.
- An H 2 sensor thus has the advantage that it responds on the one hand safely, if any odor molecules or air components are present, which are due to human digestion, and on the other hand, a false response to eg cosmetics is avoided.
- Suitable H 2 sensors are also available from FIS Inc. (see Products Review, Sensors and Systems Technology, revised June, 1998, version 4.2 of Vis Inc.), eg Model SB 19.
- the deodorizing device preferably has a controller which responds to the output signal of the sensor and controls the fan device. Once the controller is activated, the fan is turned on and the odor sensor is put into operation. In order to keep the power consumption as low as possible, the fan device is initially only switched to a standby state in which a relatively small air flow is generated. Only when the sensor indicates the presence of odor molecules, the fan device is switched to full power (operating state).
- the fan device operates in the standby state, that is, when the sensor detects no odor molecules, such as half power, while it is switched to full power when the sensor detects the presence of odor molecules.
- the fan device may include one or more fans. If the fan device contains two fans, they can have different powers, with the controller then only switching on the low-power fan in the standby state and then both fans or the fan with the higher power in the operating state.
- the fan device has only a single fan, then it is operated in the standby state at a relatively low speed, while it is operated in the operating state at full speed.
- the fan device has only a single fan, but this is to be understood that also several fans may be present, which are controlled in the manner described.
- the fan can be of any type, eg radial fan, cross-flow fan, tangential fan. Preferably, it is a Axial fan. A maximum output of about 60 liters per minute is generally sufficient.
- the power consumption of the device according to the invention is composed of that of the fan with about 1500 mW, the control of a few mW and that of the sensor of about 120 mW.
- the power consumption of the sensor is relatively high because it is connected to a small heating element.
- the sensitivity of the sensor requires that it be heated to at least about 30 ° C. Added to this is the power consumption of the switching device, if it works by means of a piezoelectric pressure transducer. This power consumption is about 2 ⁇ W.
- the toilet is used 8 times a day for defecation, with the ventilator then running for 1 minute and 10 times for urinating only, whereby the ventilator then runs at half power for one minute only ,
- the specified frequency of use will result in an annual power consumption of 13 Wh and possibly for a piezoelectric pressure transducer of 0.0173 Wh.
- This energy requirement of A total of about 130 Wh can be covered by four nickel-iron batteries of type D (mono-cells).
- the deodorizing device may be an activated carbon filter or an ionizing device.
- the deodorizing device is an activated carbon filter, it is preferably provided with a basic or acid prefilter.
- the activated carbon filter is preferably provided with an antibacterial agent, e.g. Silver, doped.
- Suitable activated carbon filters are available from CAMFIL (Sweden).
- the deodorizing device When the deodorizing device is an ionizing device, it is controlled similarly to the fan depending on the odor signal of the sensor. It is turned on, when the sensor indicates the presence of oxidizable odor molecules.
- the power of the ionization device can be controlled in dependence on the amplitude of the odor signal of the sensor. This ensures that the amount of air ions and ozone produced by the ionization device is just about as large as is necessary for the oxidation of the odor molecules. The generation of a substantial amount of excess air ions and excess ozone and the associated pungent odor are avoided.
- the ionizing tube may be a glass hollow cylinder having an outer diameter of 20 mm, a cylinder height of 50 mm and a wall thickness of 0.8 mm. On the inside and outside of the glass cylinder, flat, grid-shaped electrodes are attached. The ends of the cylindrical tube may be open or closed.
- the high voltage unit of the ionization device generates a voltage of 1 to 1.8 kV with a frequency of 8 to 13 kHz, in the previously described ionization tube preferably an AC voltage of 1.5 kV at a frequency of 10 kHz.
- the alternating voltage is applied in the form of rectangular pulses with a frequency, for example in the range of 50 Hz, to the electrodes of the ionization tube.
- the control of the ionization power, ie the amount of generated air ions and ozone molecules, is controlled by changing the duration of the square pulses and their spacing (duty cycle). There is either no voltage at the ionization tube or a certain set high voltage, eg 1.5 kV.
- the activated carbon filter can be regenerated, for example by heating.
- the sensor may be arranged in front of, behind or beside the ionization device in the direction of the airflow generated by the fan. It is only important that the sensor is located within the air flow generated by the fan before this air flow exits back into the room. If the sensor is arranged behind the ionization device, it must be taken into account when determining the control curve that some of the oxidizable odor molecules have already been oxidized before they could reach the sensor. The dependence of the power of the ionization device on the sensor signal then has at least partially the character of a control.
- the sensor then has a total of three functions: firstly, the ionization device is switched on as soon as the sensor detects oxidizable odor molecules, secondly the sensor controls the performance of the ionization device depending on the concentration of the detected odor molecules and thirdly the performance of the fan is increased as soon as the sensor detects oxidizable odor molecules.
- the controller When using a VOC sensor, the controller preferably operates so that the odor signal that controls the fan is not derived from the absolute level of the signal from the VOC sensor, but from the first derivative of that signal, ie, the odor signal from an increase of the output signal of the VOC sensor is generated. It has been shown that this improves the response reliability, since the VOC sensor responds, for example, to the vapors of cleaning agents or perfumes, the concentration changes in such "odor molecules", however, are much slower.
- the threshold of the increase, ie the first one Deriving the curve representing the time course of the concentration of oxidizable odor molecules at which the odor signal is generated to start the fan can be determined experimentally.
- a timer Upon reaching the threshold value, a timer is triggered, which switches the fan to full power for a certain time, eg 1 minute. If the threshold is reached again within this period, the timer is triggered again. The fan is then switched to full power as soon as the threshold is reached and remains at full power until the end of the specified time period, eg 1 minute, after falling below the threshold value.
- the thus derived odor or control signal for the fan does not indicate the absolute concentration of the odor molecules, and therefore the signal is not suitable for controlling the performance of an ionizer.
- an activated carbon filter is used as a deodorizing device, or by the controller is additionally output the signal representing the absolute concentration of the odor molecules. And this signal is used to control the performance of the ionizer.
- the power consumption of the deodorizing device can be kept so low that a battery is sufficient as a power source, and at a normal frequency of use once a year, the batteries must be replaced.
- the deodorizing device is suitably formed as a compact module (deodorizing module DOM) containing the fan device, the sensor, the deodorizing device (activated carbon filter or ionizing device with ionizing tube and high voltage unit), the controller and the power supply for these components.
- Power can be supplied via the mains using a power supply with a mains transformer. As mentioned, however, the power supply preferably takes place via a battery.
- the DOM is suitably waterproof and made of a material that is resistant to the common household cleaners with citric acid.
- the control of the deodorizing device can be designed so that it can be operated both with batteries as power source as well as by means of a power supply via the mains and that it behaves differently depending on the power source. If a mains connection is used as the power source, economical power consumption is less important and the controller can be operated continuously and the sensor can also work continuously. About the switching device then only the fan is switched. In a battery as a power source, however, a low power consumption is particularly important, so that then the controller and thus the odor sensor are switched by means of the switching device.
- the control can e.g. be connected via a five-core cable to the power source, with different wires for power supply from a battery and a power supply are used.
- the deodorizing module can be placed in the rear of the toilet bowl, for example below the drainpipe or trap, where there is generally enough space available. At a possibly existing cistern and at the connections of the cistern and the drain no changes are necessary.
- the deodorizing module can also be installed in the cistern, e.g. be arranged in the lower region, wherein the intake pipe is passed via a separate connection or via a branch from the flushing pipe to the deodorizing module.
- the DOM will be suspended as a compact unit at the lower end of the mounting bolt of the stationary hinge part of the seat board.
- Many toilet bowls are waisted at this point, so that there is room for the DOM on one side of the toilet bowl, while on the opposite side in the corresponding room, the batteries for the power supply can be installed. These are also attached to the bottom projecting end of the outer sleeve.
- This arrangement of the DOM is particularly useful in the above-mentioned integration of the switching device in the attachment of the stationary hinge part, in which this hinge part is fixed to an inner sleeve which slides in an outer sleeve and is supported by a spring element and its displacement Switching device operated.
- the DOM can be suspended by means of a snap ring at the lower end of the outer sleeve.
- the fan can also be used as a separate unit on the back of the toilet bowl, e.g. be arranged above or below the drain neck. This arrangement is particularly recommended if a particularly strong fan is to be used, which requires more space, or if two fans are used. The strong fan can then be placed on the back of the toilet bowl and the weaker fan in the DOM.

Der Erfindung liegt die Aufgabe zugrunde, eine Toilettenausstattung zu schaffen, mit der lästige Gerüche sehr wirksam und zuverlässig unterdrückt werden können, wobei die Gefahr eines Eintritts von Spülwasser in die Deodorisierungsvorrichtung vermieden wird.The invention has for its object to provide a toilet equipment with the annoying odors can be suppressed very effective and reliable, the risk of ingress of rinse water is avoided in the deodorizing.
Diese Aufgabe wird bei einer Toilettenausstattung der eingangs beschriebenen Art dadurch gelöst, dass der Spülwasserstutzen Verengungen an den Stellen aufweist, an denen der Spülwasserstutzen in den ringförmigen Kanal mündet und dass der mindestens eine Absaugkanal in Strömungsrichtung des Spülwassers nach den Verengungen von dem ringförmigen Kanal abzweigt.This object is achieved in a toilet equipment of the type described above in that the Spülwasserstutzen has constrictions at the points at which the Spülwasserstutzen opens into the annular channel and that the at least one suction channel branches off in the flow direction of the rinsing water after the constrictions of the annular channel.
Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Preferred embodiments of the invention are the subject of the dependent claims.
Übliche WC-Becken haben am oberen Rand einen verdeckten ringförmigen Kanal mit Austrittsöffnungen für das Spülwasser. Der ringförmige Kanal kann auch einen vollständigen oder teilweise offenen Spülkanal statt der gestochenen Austrittsöffnungen haben. In diesen Kanal mündet am rückwärtigen Ende des WC-Beckens ein Spülwasserstutzen, in den das Spülrohr mit einer Dichtungsmanschette eingeschoben wird. Die Absaugkanäle sind bei dieser Ausgestaltung der Erfindung an den ringförmigen Kanal angesetzt. Über den ringförmigen Kanal und die beiden davon abgehenden Absaugkanäle, die mit dem Ansaugrohr des DOM verbunden sind, wird die Luft aus dem Inneren des WC-Beckens abgesaugt und durch das DOM geleitet.Usual toilet bowls have at the upper edge of a hidden annular channel with outlet openings for the rinse water. The annular channel may also have a complete or partially open flushing channel instead of the pierced outlet openings to have. In this channel opens at the rear end of the toilet bowl a Spülwasserstutzen, in which the flushing pipe is inserted with a sealing sleeve. The suction channels are attached in this embodiment of the invention to the annular channel. The air is sucked out of the interior of the toilet bowl and passed through the DOM via the annular channel and the two outgoing exhaust ducts, which are connected to the suction pipe of the DOM.
Diese Absaugkanäle sind zweckmäßig in der Keramik des WC-Beckens ausgebildet und haben an ihrem hinteren Ende auf der Oberseite Öffnungen zur Verbindung mit dem Ansaugrohr der Deodorisierungsvorrichtung. Zweckmäßig erfolgt diese Verbindung über ein flexibles Schlauchstück.These suction channels are suitably formed in the ceramic of the toilet bowl and have at its rear end on the top openings for connection to the suction pipe of the deodorizing device. Appropriately, this connection is made via a flexible hose piece.
Der Spülwasserstutzen weist Verengungen an den Stellen auf, an denen der Spülwasserstutzen mit dem ringförmigen Kanal verbunden ist. Die Verengungen sind so bemessen, dass der Druckabfall der Spülwasserströmung im Wesentlichen in ihnen stattfindet und sich das Spülwasser nach den Verengungen im Wesentlichen drucklos in dem ringförmigen Kanal verteilt und durch die Öffnungen in das WC-Becken austritt. Die Absaugkanäle zweigen dabei nach den Verengungen von dem ringförmigen Kanal ab, so dass das Spülwasser nicht in die Absaugkanäle gedrückt wird.The Spülwasserstutzen has constrictions at the points where the Spülwasserstutzen is connected to the annular channel. The constrictions are dimensioned such that the pressure drop of the flushing water flow substantially takes place in them and the flushing water is distributed after the constrictions substantially without pressure in the annular channel and exits through the openings in the toilet bowl. The suction channels branch off after the constrictions of the annular channel, so that the rinse water is not pressed into the suction channels.
Die Deodorisierungsvorrichtung weist im Allgemeinen eine Lüftereinrichtung zum Absaugen der Luft aus dem Innenbereich des WC-Beckens und eine Deodorisierungseinrichtung zum Beseitigen von Geruchsmolekülen auf. Der Lüfter saugt über das Ansaugrohr Luft an und fördert sie zu der Deodorisierungseinrichtung, die ein Aktivkohlefilter oder eine Ionisierungseinrichtung sein kann.The deodorizing apparatus generally has a fan means for sucking the air from the inside of the toilet bowl and a deodorizing means for removing odor molecules. The fan draws in air via the intake pipe and delivers it to the deodorizing device, which may be an activated carbon filter or an ionizing device.
Vorzugsweise enthält die Deodorisierungsvorrichtung ferner eine Schalteinrichtung, durch die die Lüftereinrichtung bei Benutzung der Toilette eingeschaltet wird. Strom wird dadurch nur während der Benutzung der Toilette verbraucht. Die Schalteinrichtung kann ein Schalter sein, der unter dem Sitzbrett angeordnet ist und beim Niederdrücken des Sitzbrettes einen Stromkreis schließt. Es können aber auch bekannte Einrichtungen wie kapazitive Sensoren oder Infrarotsensoren verwendet werden, um die Gegenwart einer Person und damit die Benutzung der Toilette festzustellen.Preferably, the deodorizing device further includes a switching device by which the fan device is turned on when using the toilet. Electricity is thereby only consumed while using the toilet. The switching device may be a switch which is arranged under the seat board and closes a circuit when depressing the seat board. However, known devices such as capacitive sensors or infrared sensors can be used to detect the presence of a person and thus the use of the toilet.
Die Schalteinrichtung kann auch ein piezoelektrischer Druckwandler sein, der in eine Unterlegscheibe integriert ist, die zwischen dem stationären Scharnierteil des Sitzbrettes und der Oberseite des WC-Beckens angeordnet ist. Wenn sich der Benutzer auf das Sitzbrett setzt, so wird auf den piezoelektrischen Wandler Druck ausgeübt, so dass er seinen Widerstandswert ändert, und zwar verringert. Der dadurch fließende Strom wird als Benutzungssignal von der Steuerung aufgenommen.The switching means may also be a piezoelectric pressure transducer integrated with a washer disposed between the stationary hinge part of the seat board and the top of the WC bowl. As the user sits down on the seat board, pressure is applied to the piezoelectric transducer to change its resistance, and that is reduced. The current flowing therethrough is received as a use signal from the controller.
Eine weitere Möglichkeit besteht darin, eine der beiden Befestigungsschrauben des stationären Scharnierteils des Sitzbrettes verschiebbar in der zu der Befestigung dieser Schraube vorgesehenen Öffnung in der Oberseite des WC-Beckens zu lagern und durch ein Federelement abzustützen. Die Befestigungsschraube wird gegen die federnde Abstützung etwas nach unten gedrückt, wenn sich eine Person auf das Sitzbrett setzt. Diese Verlagerung der Befestigungsschraube wird dann dazu verwendet, um einen auf der Unterseite des Randes des WC-Beckens angebrachten Schalter zu betätigen, der die Schalteinrichtung darstellt.Another possibility is to store one of the two fastening screws of the stationary hinge part of the seat board displaceable in the opening provided for the attachment of this screw opening in the top of the toilet bowl and support it by a spring element. The fixing screw is pressed down slightly against the resilient support when a person sits down on the seat board. This displacement of the fastening screw is then used to actuate a switch mounted on the underside of the edge of the toilet bowl, which constitutes the switching device.
Diese Ausführungsform kann dadurch realisiert werden, dass die Befestigungsschraube in einer inneren Hülse befestigt ist, die wiederum in einer äußeren Hülse vertikal verschiebbar gelagert ist. Beide Hülsen haben an ihrem oberen Ende einen scheibenförmigen Flansch und zwischen beiden Flanschen ist ein elastischer Ring eingefügt. Die innere Hülse steht am unteren Ende über die äußere Hülse hervor, und an ihrem unteren Ende ist ein Betätigungsarm befestigt, der im Normalzustand von unten gegen einen Mikroschalter drückt, der am unteren Ende der äußeren Hülse festgelegt ist. Wenn sich der Benutzer der Toilette auf das Sitzbrett setzt, so wird die innere Hülse gegen die elastische Kraft des Ringes nach unten gedrückt, so dass der Mikroschalter freigegeben wird. Der Mikroschalter ist so ausgelegt, dass er dadurch einen Stromkreis schließt, wodurch die Steuerung der Deodorisierungsvorrichtung aktiviert wird.This embodiment can be realized in that the fastening screw is secured in an inner sleeve, which in turn is mounted vertically displaceable in an outer sleeve. Both sleeves have at their upper end a disc-shaped flange and between the two flanges an elastic ring is inserted. The inner sleeve protrudes at the lower end over the outer sleeve, and at its lower end an actuating arm is fixed, which presses in the normal state from below against a micro-switch, which at the lower end of the outer sleeve is fixed. When the user of the toilet sits down on the seat board, the inner sleeve is pressed down against the elastic force of the ring so that the microswitch is released. The microswitch is designed to close a circuit thereby activating the control of the deodorizing device.
Die Deodorisierungsvorrichtung weist vorzugsweise ferner einen Geruchssensor auf, der ein Ausgangssignal in Abhängigkeit von vorhandenen oxidierbaren Geruchsmolekülen oder bestimmten Gasmolekülen liefert.The deodorizing device preferably further comprises an odor sensor which provides an output signal depending on existing oxidizable odor molecules or certain gas molecules.
Geeignet ist insbesondere ein VOC(Volatile Organic Compound - flüchtige organische Verbindung)-Sensor, vorzugsweise ein Halbleiter-Zinnoxid-Sensor, der oxidierbare Gasbestandteile in der Luft feststellt. Derartige Sensoren sind allgemein bekannt und zum Beispiel von der Firma FIS Inc., 2-5-26, Hachizuka, Ikeda, Osaka, 563-0024 Japan, erhältlich. Geeignet ist z.B. der FIS Gassensor SB-AQ1A.Particularly suitable is a VOC (Volatile Organic Compound) sensor, preferably a semiconductor tin oxide sensor, which detects oxidizable gas components in the air. Such sensors are well known and are available, for example, from FIS Inc., 2-5-26, Hachizuka, Ikeda, Osaka, 563-0024 Japan. It is suitable, e.g. the FIS gas sensor SB-AQ1A.
Geeignet ist auch ein H2-Sensor. Wasserstoff ist zwar ein geruchloses Gas, kann jedoch als Leitgas verwendet werden, da es immer bei der menschlichen Verdauung gebildet wird, während die anderen Gasbestandteile z.B. Methan oder H2S in Abhängigkeit von der aufgenommenen Nahrung im größeren oder kleineren Umfang oder überhaupt nicht gebildet werden. Gleichzeitig hat Wasserstoff den Vorteil, dass es nicht in Parfums und ähnlichen Kosmetika verwendet wird, so dass ein fälschliches Ansprechen des Sensors auf derartige Kosmetika verhindert wird. Ein H2-Sensor hat damit den Vorteil, dass er einerseits sicher anspricht, wenn irgendwelche Geruchsmoleküle oder Luftbestandteile vorhanden sind, die von der menschlichen Verdauung herrühren, und andererseits ein fälschliches Ansprechen auf z.B. Kosmetika vermieden wird. Geeignete H2-Sensoren sind ebenfalls von der Firma FIS Inc. erhältlich (siehe Products Review, Sensors and Systems Technology, revised June, 1998, Version 4.2 der Firma Vis Inc.), z.B. das Modell SB 19.Also suitable is an H 2 sensor. Although hydrogen is an odorless gas, it can be used as a guide gas, since it is always formed in human digestion, while the other gas constituents, such as methane or H 2 S depending on the ingested food to a greater or lesser extent or not formed , At the same time, hydrogen has the advantage that it is not used in perfumes and similar cosmetics, so that a false response of the sensor to such cosmetics is prevented. An H 2 sensor thus has the advantage that it responds on the one hand safely, if any odor molecules or air components are present, which are due to human digestion, and on the other hand, a false response to eg cosmetics is avoided. Suitable H 2 sensors are also available from FIS Inc. (see Products Review, Sensors and Systems Technology, revised June, 1998, version 4.2 of Vis Inc.), eg Model SB 19.
Ferner weist die Deodorisierungsvorrichtung vorzugsweise eine Steuerung auf, die auf das Ausgangssignal des Sensors anspricht und die Lüftereinrichtung steuert. Sobald die Steuerung aktiviert ist, wird die Lüftereinrichtung eingeschaltet und der Geruchssensor in Betrieb gesetzt. Um den Stromverbrauch möglichst niedrig zu halten, wird die Lüftereinrichtung zunächst nur in einen Bereitschaftszustand geschaltet, in dem ein relativ geringer Luftstrom erzeugt wird. Erst wenn der Sensor das Vorhandensein von Geruchsmolekülen anzeigt, wird die Lüftereinrichtung auf volle Leistung geschaltet (Betriebszustand).Furthermore, the deodorizing device preferably has a controller which responds to the output signal of the sensor and controls the fan device. Once the controller is activated, the fan is turned on and the odor sensor is put into operation. In order to keep the power consumption as low as possible, the fan device is initially only switched to a standby state in which a relatively small air flow is generated. Only when the sensor indicates the presence of odor molecules, the fan device is switched to full power (operating state).
Vorzugsweise arbeitet die Lüftereinrichtung im Bereitschaftszustand, d.h., wenn der Sensor keine Geruchsmoleküle feststellt, etwa mit halber Leistung, während sie dann, wenn der Sensor das Vorhandensein von Geruchsmolekülen feststellt, auf volle Leistung umgeschaltet wird.Preferably, the fan device operates in the standby state, that is, when the sensor detects no odor molecules, such as half power, while it is switched to full power when the sensor detects the presence of odor molecules.
Die Lüftereinrichtung kann einen oder mehrere Lüfter aufweisen. Enthält die Lüftereinrichtung zwei Lüfter, so können diese unterschiedliche Leistungen haben, wobei die Steuerung dann im Bereitschaftszustand nur den Lüfter mit der niedrigen Leistung einschaltet und im Betriebszustand dann beide Lüfter oder den Lüfter mit der höheren Leistung.The fan device may include one or more fans. If the fan device contains two fans, they can have different powers, with the controller then only switching on the low-power fan in the standby state and then both fans or the fan with the higher power in the operating state.
Hat die Lüftereinrichtung nur einen einzigen Lüfter, so wird dieser im Bereitschaftszustand mit einer relativ kleinen Drehzahl betrieben, während er im Betriebszustand mit voller Drehzahl betrieben wird.If the fan device has only a single fan, then it is operated in the standby state at a relatively low speed, while it is operated in the operating state at full speed.
Der Einfachheit halber wird nachfolgend davon ausgegangen, dass die Lüftereinrichtung nur einen einzigen Lüfter aufweist, wobei dies jedoch so zu verstehen ist, dass auch mehrere Lüfter vorhanden sein können, die in der beschriebenen Weise gesteuert werden.For simplicity, it is assumed below that the fan device has only a single fan, but this is to be understood that also several fans may be present, which are controlled in the manner described.
Der Lüfter kann von jeder Bauart sein, z.B. Radiallüfter, Querstromlüfter, Tangentiallüfter. Vorzugsweise ist er ein Axiallüfter. Eine maximale Leistung von etwa 60 Liter pro Minute ist im Allgemeinen ausreichend.The fan can be of any type, eg radial fan, cross-flow fan, tangential fan. Preferably, it is a Axial fan. A maximum output of about 60 liters per minute is generally sufficient.
Der Stromverbrauch der erfindungsgemäßen Vorrichtung setzt sich zusammen aus dem des Lüfters mit etwa 1500 mW, dem der Steuerung von einigen wenigen mW und dem des Sensors von etwa 120 mW. Der Stromverbrauch des Sensors ist relativ hoch, da er mit einem kleinen Heizelement verbunden ist. Die Empfindlichkeit des Sensors erfordert, dass dieser auf mindestens etwa 30 °C erwärmt wird. Hinzukommt noch der Stromverbrauch der Schalteinrichtung, falls diese mittels eines piezoelektrischen Druckwandlers arbeitet. Dieser Stromverbrauch beträgt etwa 2 µW. Es wird für die Abschätzung des Stromverbrauchs davon ausgegangen, dass die Toilette 8 Mal pro Tag für Stuhlgang verwendet wird, wobei der Lüfter dann jeweils 1 Minute läuft, sowie 10 Mal nur zum Urinieren, wobei der Lüfter dann für eine Minute nur mit halber Leistung läuft. Der jährliche Stromverbrauch des Lüfters ist dann (72 Wh + 45 Wh =) 117 Wh. Für den Sensor fällt bei der angegebenen Benutzungsfrequenz ein jährlicher Stromverbrauch von 13 Wh an und gegebenenfalls für einen piezoelektrischen Druckwandler ein solcher von 0,0173 Wh. Dieser Energiebedarf von insgesamt etwa 130 Wh lässt sich durch vier Nickeleisenbatterien des Typs D (Mono-Zellen) decken.The power consumption of the device according to the invention is composed of that of the fan with about 1500 mW, the control of a few mW and that of the sensor of about 120 mW. The power consumption of the sensor is relatively high because it is connected to a small heating element. The sensitivity of the sensor requires that it be heated to at least about 30 ° C. Added to this is the power consumption of the switching device, if it works by means of a piezoelectric pressure transducer. This power consumption is about 2 μW. It is assumed that the toilet is used 8 times a day for defecation, with the ventilator then running for 1 minute and 10 times for urinating only, whereby the ventilator then runs at half power for one minute only , The annual power consumption of the fan is then (72 Wh + 45 Wh =) 117 Wh. For the sensor, the specified frequency of use will result in an annual power consumption of 13 Wh and possibly for a piezoelectric pressure transducer of 0.0173 Wh. This energy requirement of A total of about 130 Wh can be covered by four nickel-iron batteries of type D (mono-cells).
Die Deodorisierungseinrichtung kann ein Aktivkohlefilter oder eine Ionisierungseinrichtung sein.The deodorizing device may be an activated carbon filter or an ionizing device.
Wenn die Deodorisierungseinrichtung ein Aktivkohlefilter ist, so ist dieser vorzugsweise mit einem basischen oder sauren Vorfilter versehen. Zur Unterdrückung von Keimen ist der Aktivkohlefilter vorzugsweise mit einem antibakteriellen Mittel, z.B. Silber, dotiert. Geeignete Aktivkohlefilter sind von der Firma CAMFIL (Schweden) erhältlich.If the deodorizing device is an activated carbon filter, it is preferably provided with a basic or acid prefilter. For the suppression of germs, the activated carbon filter is preferably provided with an antibacterial agent, e.g. Silver, doped. Suitable activated carbon filters are available from CAMFIL (Sweden).
Wenn die Deodorisierungseinrichtung eine Ionisierungseinrichtung ist, so wird sie ähnlich wie der Lüfter in Abhängigkeit von dem Geruchssignal des Sensors gesteuert. Sie wird eingeschaltet, wenn der Sensor das Vorhandensein oxidierbarer Geruchsmoleküle anzeigt. Außerdem kann die Leistung der Ionisierungseinrichtung in Abhängigkeit von der Amplitude des Geruchssignals des Sensors gesteuert werden. Dadurch wird erreicht, dass die von der Ionisierungseinrichtung produzierte Menge an Luftionen und Ozon gerade etwa so groß ist, wie es zur Oxidation der Geruchsmoleküle notwendig ist. Die Erzeugung einer wesentlichen Menge überschüssiger Luftionen und überschüssigen Ozons und der damit verbundene beißende Geruch werden vermieden.When the deodorizing device is an ionizing device, it is controlled similarly to the fan depending on the odor signal of the sensor. It is turned on, when the sensor indicates the presence of oxidizable odor molecules. In addition, the power of the ionization device can be controlled in dependence on the amplitude of the odor signal of the sensor. This ensures that the amount of air ions and ozone produced by the ionization device is just about as large as is necessary for the oxidation of the odor molecules. The generation of a substantial amount of excess air ions and excess ozone and the associated pungent odor are avoided.
Die Ionisierungsröhre kann ein Glas-Hohlzylinder mit einem Außendurchmesser von 20 mm, einer Zylinderhöhe von 50 mm und einer Wandstärke von 0,8 mm sein. Auf der Innen- und Außenseite des Glaszylinders sind flächige, gitterförmige Elektroden angebracht. Die Enden der zylinderförmigen Röhre können offen oder verschlossen sein.The ionizing tube may be a glass hollow cylinder having an outer diameter of 20 mm, a cylinder height of 50 mm and a wall thickness of 0.8 mm. On the inside and outside of the glass cylinder, flat, grid-shaped electrodes are attached. The ends of the cylindrical tube may be open or closed.
Die Hochspannungseinheit der Ionisierungseinrichtung erzeugt eine Spannung von 1 bis 1,8 kV mit einer Frequenz von 8 bis 13 kHz, bei der vorausgehend beschriebenen Ionisierungsröhre vorzugsweise eine Wechselspannung von 1,5 kV bei einer Frequenz von 10 kHz. Die Wechselspannung wird in Form von Rechteckimpulsen mit einer Frequenz z.B. im Bereich von 50 Hz an die Elektroden der Ionisationsröhre angelegt. Die Steuerung der Ionisationsleistung, d.h. der Menge der erzeugten Luftionen und der Ozonmoleküle, wird dadurch gesteuert, dass die Dauer der Rechteckimpulse und deren Abstand verändert wird (Tastverhältnis). An der Ionisationsröhre liegt damit entweder keine Spannung an oder eine bestimmte fest eingestellte Hochspannung, z.B. 1,5 kV. Wenn Ionisation stattfindet, dann erfolgt sie dadurch mit der einmal gefundenen optimalen Spannung, bei der die Menge der erzeugten Luftionen und der Ozonmoleküle pro Zeiteinheit weitgehend konstant ist. Es kann sich bisweilen das Problem ergeben, dass die Luft nach dem Durchgang durch die Ionisierungseinrichtung noch einen geringen Anteil an Ozon enthält. In diesen Fällen kann es vorteilhaft sein, der Ionisierungseinrichtung am Auslassende noch ein Aktivkohlefilter nachzuschalten. Da der größte Anteil der oxidierbaren Gase und des Ozons bereits vor dem Aktivkohlefilter miteinander reagieren, wird das Aktivkohlefilter wenig belastet, so dass es eine sehr hohe Standzeit hat. In bekannter Weise kann das Aktivkohlefilter z.B. durch Erhitzen regeneriert werden.The high voltage unit of the ionization device generates a voltage of 1 to 1.8 kV with a frequency of 8 to 13 kHz, in the previously described ionization tube preferably an AC voltage of 1.5 kV at a frequency of 10 kHz. The alternating voltage is applied in the form of rectangular pulses with a frequency, for example in the range of 50 Hz, to the electrodes of the ionization tube. The control of the ionization power, ie the amount of generated air ions and ozone molecules, is controlled by changing the duration of the square pulses and their spacing (duty cycle). There is either no voltage at the ionization tube or a certain set high voltage, eg 1.5 kV. If ionization takes place, then it is done with the optimum voltage once found, in which the amount of air ions generated and the ozone molecules per unit time is largely constant. It can sometimes be the problem that the air after passing through the ionizer still contains a small amount of ozone. In these cases, it may be advantageous to still insert the ionization device at the outlet end Downstream activated carbon filter. Since most of the oxidizable gases and ozone react with each other before the activated carbon filter, the activated carbon filter is little loaded, so that it has a very long life. In known manner, the activated carbon filter can be regenerated, for example by heating.
Der Sensor kann in Richtung der von dem Lüfter erzeugten Luftströmung vor, hinter oder neben der Ionisierungseinrichtung angeordnet sein. Wichtig ist nur, dass der Sensor innerhalb des von dem Lüfter erzeugten Luftstroms angeordnet ist, bevor dieser Luftstrom wieder in den Raum austritt. Wenn der Sensor hinter der Ionisierungseinrichtung angeordnet ist, so ist bei der Festlegung der Steuerungskurve zu berücksichtigen, dass ein Teil der oxidierbaren Geruchsmoleküle bereits aufoxidiert ist, bevor sie den Sensor erreichen konnten. Die Abhängigkeit der Leistung der Ionisierungseinrichtung von dem Sensorsignal hat dann zumindest zum Teil den Charakter einer Regelung.The sensor may be arranged in front of, behind or beside the ionization device in the direction of the airflow generated by the fan. It is only important that the sensor is located within the air flow generated by the fan before this air flow exits back into the room. If the sensor is arranged behind the ionization device, it must be taken into account when determining the control curve that some of the oxidizable odor molecules have already been oxidized before they could reach the sensor. The dependence of the power of the ionization device on the sensor signal then has at least partially the character of a control.
Der Sensor hat dann insgesamt eine dreifache Funktion: Erstens wird die Ionisierungseinrichtung eingeschaltet, sobald der Sensor oxidierbare Geruchsmoleküle feststellt, zweitens steuert der Sensor in Abhängigkeit von der Konzentration der festgestellten Geruchsmoleküle die Leistung der Ionisierungseinrichtung und drittens wird die Leistung des Lüfters erhöht, sobald der Sensor oxidierbare Geruchsmoleküle feststellt.The sensor then has a total of three functions: firstly, the ionization device is switched on as soon as the sensor detects oxidizable odor molecules, secondly the sensor controls the performance of the ionization device depending on the concentration of the detected odor molecules and thirdly the performance of the fan is increased as soon as the sensor detects oxidizable odor molecules.
Bei der Verwendung eines VOC-Sensors arbeitet die Steuerung vorzugsweise so, dass das Geruchssignal, das den Lüfter steuert, nicht aus der absoluten Höhe des Signals des VOC-Sensors abgeleitet wird, sondern aus der ersten Ableitung dieses Signals, d.h., dass das Geruchssignal von einem Ansteigen des Ausgangssignals des VOC-Sensors erzeugt wird. Es hat sich gezeigt, dass dadurch die Ansprechsicherheit verbessert wird, da der VOC-Sensor zwar z.B. auch auf die Dämpfe von Reinigungsmitteln oder Parfüms anspricht, die Konzentrationsänderungen bei derartigen "Geruchsmolekülen" jedoch wesentlich langsamer sind. Der Schwellwert des Anstiegs, d.h. der ersten Ableitung der Kurve, die den zeitlichen Verlauf der Konzentration der oxidierbaren Geruchsmoleküle wiedergibt, bei dem das Geruchssignal zum Hochfahren des Lüfters erzeugt wird, kann experimentell ermittelt werden. Beim Erreichen des Schwellwertes wird ein Zeitgeber getriggert, der den Lüfter für eine bestimmte Zeit, z.B. 1 Minute, auf volle Leistung schaltet. Wenn der Schwellwert innerhalb dieser Zeitspanne nochmals erreicht wird, so wird der Zeitgeber nochmals getriggert. Der Lüfter wird damit auf volle Leistung geschaltet, sobald der Schwellwert erreicht wird und bleibt auf voller Leistung bis zum Ende der vorgegebenen Zeitspanne, z.B. 1 Minute, nach dem Unterschreiten des Schwellwertes.When using a VOC sensor, the controller preferably operates so that the odor signal that controls the fan is not derived from the absolute level of the signal from the VOC sensor, but from the first derivative of that signal, ie, the odor signal from an increase of the output signal of the VOC sensor is generated. It has been shown that this improves the response reliability, since the VOC sensor responds, for example, to the vapors of cleaning agents or perfumes, the concentration changes in such "odor molecules", however, are much slower. The threshold of the increase, ie the first one Deriving the curve representing the time course of the concentration of oxidizable odor molecules at which the odor signal is generated to start the fan can be determined experimentally. Upon reaching the threshold value, a timer is triggered, which switches the fan to full power for a certain time, eg 1 minute. If the threshold is reached again within this period, the timer is triggered again. The fan is then switched to full power as soon as the threshold is reached and remains at full power until the end of the specified time period, eg 1 minute, after falling below the threshold value.
Das auf diese Weise abgeleitete Geruchs- oder Steuerungssignal für den Lüfter gibt nicht die absolute Konzentration der Geruchsmoleküle an, und das Signal ist daher nicht zur Steuerung der Leistung einer Ionisierungseinrichtung geeignet. Zweckmäßig wird daher bei dieser Ableitung des Steuerungssignals ein Aktivkohlefilter als Deodorisierungseinrichtung verwendet, oder von der Steuerung wird zusätzlich das Signal ausgegeben, das die absolute Konzentration der Geruchsmoleküle wiedergibt. Und dieses Signal wird zur Steuerung der Leistung der Ionisierungseinrichtung verwendet.The thus derived odor or control signal for the fan does not indicate the absolute concentration of the odor molecules, and therefore the signal is not suitable for controlling the performance of an ionizer. Appropriately, therefore, in this derivation of the control signal, an activated carbon filter is used as a deodorizing device, or by the controller is additionally output the signal representing the absolute concentration of the odor molecules. And this signal is used to control the performance of the ionizer.
Bei Verwendung eines H2-Sensors als Geruchssensor besteht, wie erwähnt, der Vorteil, dass er nicht auf "Geruchsmoleküle" anspricht, die von Reinigungsmitteln oder Parfüms stammen. Auch wird der Lüfter nicht auf volle Leistung geschaltet und wird die Ionisierungseinrichtung nicht eingeschaltet, wenn der Benutzer nur uriniert. Dabei wird nämlich kein H2-Gas gebildet.When using an H 2 sensor as an odor sensor, as mentioned, there is the advantage that it does not respond to "odor molecules" derived from detergents or perfumes. Also, the fan will not switch to full power and the ionizer will not be turned on if the user just urinates. Namely, no H 2 gas is formed.
Durch alle vorausgehend beschriebenen Maßnahmen wird es schließlich erreicht, dass der Stromverbrauch der Deodorisierungsvorrichtung so niedrig gehalten werden kann, dass eine Batterie als Stromquelle ausreicht, und bei einer normalen Benutzungsfrequenz einmal pro Jahr die Batterien gewechselt werden müssen.By all measures described above, it is finally achieved that the power consumption of the deodorizing device can be kept so low that a battery is sufficient as a power source, and at a normal frequency of use once a year, the batteries must be replaced.
Die Deodorisierungsvorrichtung ist zweckmäßig als ein kompaktes Modul (Deodorisierungsmodul-DOM) ausgebildet, das die Lüftereinrichtung, den Sensor, die Deodorisierungseinrichtung (Aktivkohlefilter oder Ionisierungseinrichtung mit Ionisierungsröhre und Hochspannungseinheit), die Steuerung und die Stromversorgung für diese Komponenten enthält. Die Stromversorgung kann über das Stromnetz mittels eines Netzteils mit einem Netztrafo erfolgen. Wie erwähnt, erfolgt die Stromversorgung jedoch vorzugsweise über eine Batterie. Das DOM ist zweckmäßig wasserdicht ausgebildet und aus einem Material hergestellt, das gegenüber den haushaltsüblichen Reinigungsmitteln mit Zitronensäure widerstandsfähig ist.The deodorizing device is suitably formed as a compact module (deodorizing module DOM) containing the fan device, the sensor, the deodorizing device (activated carbon filter or ionizing device with ionizing tube and high voltage unit), the controller and the power supply for these components. Power can be supplied via the mains using a power supply with a mains transformer. As mentioned, however, the power supply preferably takes place via a battery. The DOM is suitably waterproof and made of a material that is resistant to the common household cleaners with citric acid.
Die Steuerung der Deodorisierungsvorrichtung kann so ausgelegt werden, dass sie sowohl mit Batterien als Stromquelle als auch mittels eines Netzteils über das Stromnetz betrieben werden kann und dass sie sich in Abhängigkeit von der Stromquelle unterschiedlich verhält. Dient als Stromquelle ein Netzanschluss, so ist ein sparsamer Stromverbrauch weniger wichtig und kann die Steuerung kontinuierlich betrieben werden und auch der Sensor kontinuierlich arbeiten. Über die Schalteinrichtung wird dann nur der Lüfter geschaltet. Bei einer Batterie als Stromquelle ist dagegen ein niedriger Stromverbrauch besonders wichtig, so dass dann auch die Steuerung und damit der Geruchssensor mittels der Schalteinrichtung geschaltet werden. Die Steuerung kann z.B. über ein fünfadriges Kabel mit der Stromquelle verbunden werden, wobei unterschiedliche Adern für die Stromzuführung von einer Batterie und von einem Netzteil dienen.The control of the deodorizing device can be designed so that it can be operated both with batteries as power source as well as by means of a power supply via the mains and that it behaves differently depending on the power source. If a mains connection is used as the power source, economical power consumption is less important and the controller can be operated continuously and the sensor can also work continuously. About the switching device then only the fan is switched. In a battery as a power source, however, a low power consumption is particularly important, so that then the controller and thus the odor sensor are switched by means of the switching device. The control can e.g. be connected via a five-core cable to the power source, with different wires for power supply from a battery and a power supply are used.
Das Deodorisierungsmodul (DOM) kann im hinteren Bereich des WC-Beckens angeordnet werden, bspw. unterhalb des Abflussrohrs oder Geruchsverschlusses, wo im Allgemeinen ausreichend Platz zur Verfügung steht. An einem eventuell vorhandenen Spülkasten und an den Anschlüssen des Spülkastens und des Abflusses sind dabei keine Veränderungen notwendig.The deodorizing module (DOM) can be placed in the rear of the toilet bowl, for example below the drainpipe or trap, where there is generally enough space available. At a possibly existing cistern and at the connections of the cistern and the drain no changes are necessary.
Das Deodorisierungsmodul kann auch im Spülkasten, z.B. in dessen unterem Bereich, angeordnet werden, wobei das Ansaugrohr über einen eigenen Anschluss oder über eine Abzweigung aus dem Spülrohr zum Deodorisierungsmodul geleitet wird.The deodorizing module can also be installed in the cistern, e.g. be arranged in the lower region, wherein the intake pipe is passed via a separate connection or via a branch from the flushing pipe to the deodorizing module.
Vorzugsweise wird das DOM als kompakte Einheit am unteren Ende der Befestigungsschraube des stationären Scharnierteils des Sitzbrettes abgehängt werden. Viele WC-Becken sind an dieser Stelle tailliert, so dass auf der einen Seite des WC-Beckens Raum für die Anordnung des DOM vorhanden ist, während auf der gegenüberliegenden Seite in dem entsprechenden Raum die Batterien für die Stromversorgung angebracht werden können. Diese werden ebenfalls an dem unten vorstehenden Ende der äußeren Hülse angehängt. Diese Anordnung des DOM bietet sich insbesondere bei der oben erwähnten Integration der Schalteinrichtung in die Befestigung des stationären Scharnierteils an, bei der dieses Scharnierteil an einer inneren Hülse befestigt ist, die in einer äußeren Hülse gleitet und durch ein Federelement abgestützt ist und bei ihrer Verschiebung die Schalteinrichtung betätigt. Das DOM kann hierbei mittels eines Sprengrings am unteren Ende der äußeren Hülse abgehängt werden.Preferably, the DOM will be suspended as a compact unit at the lower end of the mounting bolt of the stationary hinge part of the seat board. Many toilet bowls are waisted at this point, so that there is room for the DOM on one side of the toilet bowl, while on the opposite side in the corresponding room, the batteries for the power supply can be installed. These are also attached to the bottom projecting end of the outer sleeve. This arrangement of the DOM is particularly useful in the above-mentioned integration of the switching device in the attachment of the stationary hinge part, in which this hinge part is fixed to an inner sleeve which slides in an outer sleeve and is supported by a spring element and its displacement Switching device operated. The DOM can be suspended by means of a snap ring at the lower end of the outer sleeve.
Der Lüfter kann auch als separate Baueinheit auf der Rückseite des WC-Beckens z.B. über oder unter dem Abflussstutzen angeordnet werden. Diese Anordnung empfiehlt sich insbesondere dann, wenn ein besonders starker Lüfter eingesetzt werden soll, der mehr Platz benötigt, oder wenn zwei Lüfter eingesetzt werden. Der starke Lüfter kann dann auf der Rückseite des WC-Beckens und der schwächere Lüfter in dem DOM angeordnet werden.The fan can also be used as a separate unit on the back of the toilet bowl, e.g. be arranged above or below the drain neck. This arrangement is particularly recommended if a particularly strong fan is to be used, which requires more space, or if two fans are used. The strong fan can then be placed on the back of the toilet bowl and the weaker fan in the DOM.

Die
In
Die Oberseite des WC-Beckens 10 hat im hinteren Bereich etwa gleichbleibende Breite, und in der Oberseite sind zwei Öffnungen 36 zur Befestigung des stationären Scharnierteils 38 des Sitzbrettes 40 vorgesehen. Unter der Oberseite ist das WC-Becken 10 im hinteren Bereich seitlich tailliert, und die Öffnungen 36 für die Sitzbrettmontage befinden sich über diesem taillierten Bereich. Auf der einen Seite des taillierten Bereiches befindet sich das DOM 30 und auf der anderen Seite ein Batteriegehäuse 42 (
Die Halterungsplatte 54 ist ein Teil des Gehäuses 66 des DOM 30. In
Über eine nicht dargestellte Öffnung in der Wand des WC-Beckens 10 ist das Ansaugrohr 28 mittels eines flexiblen Schlauches 82 mit den Absaugkanälen 22 verbunden. Das Batteriegehäuse ist auf ähnliche Weise an der anderen Seite des WC-Beckens 10 befestigt, und mittels der in
Das DOM 30 kann eine Deodorisierungseinrichtung in Form einer Ionisierungseinrichtung 86 oder eines Aktivkohlefilters 76 oder einer Kombination beider Einrichtungen aufweisen. Der Sensor 70 kann dabei jeweils ein VOC-Sensor oder ein H2-Sensor sein.The
Der Sensor 70 ist typischerweise ein Halbleiter-Zinnoxid-Sensor, der oxidierbare Gasbestandteile in der Luft feststellt. Der elektrische Widerstand des Sensors 70 ändert sich in Abhängigkeit von der Konzentration der oxidierbaren Luftbestandteile, die sich in der Luft befinden, die an den frei liegenden Oberflächen des Sensors 70 vorbei strömt.The
Die Ionisationsröhre 87 besteht aus einem Glas- oder Keramikzylinder mit zwei Elektroden auf der Innenseite und der Außenseite. Die Hochspannungseinheit 92 erzeugt eine elektrische Wechselspannung von 1,5 kV und 10 kHz, und diese Wechselspannung wird an die beiden Elektroden angelegt, wodurch Luftionen und aktiver Sauerstoff nach dem Prinzip der stillen oder dielektrisch behinderten Entladung erzeugt werden. Die Ionisierungseinrichtung arbeitet im Impulsbetrieb, d.h. die Hochspannungseinheit 92 erzeugt eine Hochspannung in Form einer Folge von Rechteck-Hochspannungsimpulsen. Dadurch wird erreicht, dass die Ionisierungseinrichtung 86 immer mit der optimalen Spannung betrieben wird, bei der stabil und reproduzierbar überwiegend Luftionen und nur ein geringer Anteil an aktiven Sauerstoffatomen erzeugt werden.The
Die Steuereinheit 94 steuert das DOM 30 in der Weise, dass im Bereitschaftszustand, d.h., wenn der Sensor 70 kein Signal abgibt, das auf das Vorhandensein von oxidierbaren Luftbestandteilen hinweist, der Lüfter 72 etwa mit seiner halben Nennleistung läuft und die Ionisierungseinrichtung 86 stromlos ist. Sobald der Sensor 70 meldet, dass oxidierbare Luftbestandteile in der angesaugten Luft vorhanden sind, wird der Lüfter 72 auf volle Leistung geschaltet und wird die Ionisierungseinrichtung 86 eingeschaltet, wobei die Leistung der Ionisierungseinrichtung 86 in Abhängigkeit von der Menge der oxidierbaren Luftbestandteile gesteuert wird. Die Steuereinheit 94 steuert die Leistung der Ionisierungseinrichtung 86 durch Verändern der Impulsdauer und/oder der Impulsabstände, wobei die Maximal-Spannung jedes Impulses im Wesentlichen konstant bei etwa 1,5 kV liegt. Die Steuerung der Ionisationsleistung erfolgt in Abhängigkeit von dem Widerstandswert des Sensors 70 mit dem Ziel, gerade die Menge an Luftionen und Sauerstoffatomen zu erzeugen, die notwendig ist, um die oxidierbaren Luftbestandteile zu oxidieren und damit zu zerstören. Die Sauerstoffatome führen zur Bildung von Ozon. Überschüssige Sauerstoffatome würden als beißender Ozongeruch wahrgenommen.The
Die Luft wird über den flexiblen Schlauch 82 angesaugt, der die Öffnungen 26 auf der Oberseite der Hörner 24 mit dem DOM 30 verbindet. Handelsübliche WC-Becken 10 haben im hinteren Bereich über oder unter dem Abflussstutzen 32 einen geeigneten Hohlraum für die Unterbringung des DOM 30. Der Anschluss des WC-Beckens 10 an den Spülkasten 102 und das Abflussrohr 108 erfolgt mittels üblicher Verbindungsteile und Manschetten.The air is drawn in via the
