Description

Die Erfindung betrifft eine Wasserspareinrichtung zur Spülung einer Toilette mittels leicht verschmutzten Grauwassers von Sanitäreinrichtungen, mit einem unter dem Niveau des Spülzulaufs der Toilette angeordneten, von einer oder mehreren Sanitäreinrichtungen gespeisten Grauwasserspeicher, einer Spülleitung, die den Grauwasserspeicher mit dem Spülzulauf der Toilette verbindet, sowie mit einer außerhalb des Grauwasserspeichers angeordneten Spülpumpe.The invention relates to a water-saving device for flushing a toilet with slightly dirty gray water from Sanitary facilities, with one below the level of the flushing inlet the toilet arranged by one or more Sanitary facilities fed gray water storage, one Flushing line that connects the gray water tank with the flushing inlet of the Toilet connects, as well as with an outside of the gray water storage arranged rinsing pump.

Bei einer herkömmlichen Toilettenspülung wird der Spülzulauf der Toilette aus einem Toilettenspülkasten über eine Fallrohrleitung mit Wasser gespeist. Dabei bewirkt der Gefälledruck des Wassers die Spülung der Toilette. Dies ist bei einer gattungsgemäßen Wasserspareinrichtung nach der DE-U-94 12 781 anders. Anstelle einer herkömmlichen Fallrohrleitung, die aus einem Toilettenspülkasten gespeist wird, sieht diese eine direkt von der Spülpumpe versorgte Spülleitung vor. Die Spülung erfolgt aufgrund des Spüldrucks der Spülpumpe.With a conventional toilet flush, the flushing inlet becomes the toilet from a toilet cistern via a downpipe fed with water. The gradient pressure causes flushing the toilet. This is one Generic water saving device according to DE-U-94 12 781 different. Instead of a conventional downpipe that comes from is fed to a toilet cistern, this sees one flushing line supplied directly by the flushing pump. The flush takes place due to the flushing pressure of the flushing pump.

Der Grauwasserspeicher der DE-U-94 12 781 weist wegen der schlechten Zugänglichkeit des Behälterinneren Reinigungs- und Hygieneprobleme auf. Der Grauwasserspeicher ist mit nur einer kleinen seitlichen Öffnung versehen, durch die der Behälterinnenraum erreichbar ist.The gray water reservoir of DE-U-94 12 781 has because of the poor accessibility of the inside of the container for cleaning and cleaning Hygiene problems. The gray water tank is with only one small side opening through which the container interior is achievable.

Darüber hinaus gestaltet sich dann, wenn eine Duschwanne vorhanden ist, die Nachrüstung des Grauwasserspeichers gemäß der DE-U-94 12 781 besonders schwierig. Die vorhandene Duschwanne muß zunächst demontiert werden, um den nachzurüstenden Grauwasserspeicher unter der Duschwanne anordnen zu können.In addition, if a shower tray is available is the retrofitting of the gray water tank according to the DE-U-94 12 781 is particularly difficult. The existing shower tray must first be dismantled in order to add the gray water tank to be retrofitted to be able to arrange under the shower tray.

Ferner ist aus der GB-A-2 266 233 eine Wasserspareinrichtung bekannt, die den Spüldruck auf herkömmliche Weise mittels Gefälledruck aus einem Toilettenspülkasten erzeugt. Dieser Gegenstand sieht keine Spülpumpe zur Erzeugung eines Spüldrucks vor. Eine Förderpumpe pumpt das Grauwasser über den Behälterrand des Toilettenspülkastens und befüllt diesen. Die Förderpumpe ist nicht dafür vorgesehen, einen Spüldruck zu erzeugen, der zur Spülung der Toilette ausreicht.Furthermore, GB-A-2 266 233 is a water saving device known, which uses the flushing pressure in a conventional manner Slope pressure generated from a toilet cistern. This The object does not see a flushing pump for generating a flushing pressure in front. A feed pump pumps the gray water over the Container rim of the toilet cistern and fills it. The The feed pump is not intended for flushing pressure generate enough to flush the toilet.

Eine weitere Wasserspareinrichtung ist aus der JP-A-05-184474 bekannt. Auch hierbei wird der Spüldruck für die Toilettenspülung auf herkömmliche Weise mittels Gefälledruck aus einem Toilettenspülkasten erzeugt.Another water saving device is from JP-A-05-184474 known. Here too the flushing pressure for flushing the toilet in a conventional manner using a gradient pressure from a Toilet cistern generated.

Der Erfindung liegt das technische Problem zugrunde, eine einfache und kostengünstige Wasserspareinrichtung zu schaffen, die mit minimalem Installationsaufwand in Betrieb genommen werden kann und deren Grauwasserspeicher zu Reinigungs- und Wartungszwecken gut zugänglich ist.The invention is based on the technical problem to create simple and inexpensive water-saving device, the put into operation with minimal installation effort can be and their gray water storage for cleaning and Is easily accessible for maintenance purposes.

Die Aufgabe wird dadurch gelöst, daß mit der Spülpumpe Festbestandteile enthaltendes Grauwasser förderbar ist, daß der Grauwasserspeicher als glattwandiges, über eine obenliegende Öffnung leicht zu reinigendes Gefäß ausgebildet und derart in eine auf dem Fußboden installierte Sanitäreinrichtung integriert ist, daß die Wanne einer Dusche den Grauwasserspeicher bildet, und daß die Duschwanne als Trittfläche für den Benutzer einen Einlegeboden mit wenigstens einer Abflußeinrichtung aufweist, über die das Grauwasser in den darunter liegenden Grauwasserspeicher fließen kann.The object is achieved in that fixed components with the flushing pump containing gray water is eligible that the Greywater storage tank as smooth-walled, over an overhead Opening easy-to-clean vessel formed and such in a sanitary facility installed on the floor is integrated is that the tub of a shower is the gray water tank forms, and that the shower tray as a step for the user a shelf with at least one drain device over which the gray water in the underlying Greywater storage can flow.

Die vorgeschlagene Wasserspareinrichtung ist sehr einfach aufgebaut. Ihre Anwendung ist vorzugsweise auf ein einzelnes Badezimmer beschränkt. Sie läßt sich daher kostengünstig herstellen und installieren. Bei der Insallation in einem vorhandenen Badezimmer kann das bestehende Rohrleitungssystem beibehalten werden.The proposed water saving device is very simple built up. Their application is preferably on a single one Bathroom limited. It can therefore be manufactured inexpensively and install. When installing in an existing one Bathrooms can keep the existing piping system become.

Der Grauwasserspeicher weist keine Fugen und Ecken auf, in denen sich Schmutz ansammeln kann. Das Grauwasser wird durch die besondere Spülpumpe mitsamt der Festbestandteile aus dem Grauwasserspeicher abgepumpt und zur Spülung der Toilette verwendet. Es findet somit ein schneller Austausch des kompletten Speicherinhalts des Grauwasserspeichers statt. Um die Verschmutzung des Grauwasserspeichers zu vermindern, kann dieser zu bestimmten Zeiten über einen Ablauf oder mittels der Spülpumpe rückstandslos entleert werden. Auf diese Weise wird das Sedimentieren der Festbestandteile des Grauwassers während der Nachtstunden verhindert. Es bildet sich kein Nährboden für Keime.The gray water tank has no joints and corners, in where dirt can accumulate. The gray water is through the special irrigation pump together with the solid components from the Gray water tank pumped out and for flushing the toilet used. This means that the entire system can be exchanged quickly Contents of the gray water storage instead. To the To reduce pollution of the gray water storage can this at certain times via a process or by means of Rinsing pump can be emptied without leaving any residue. That way the sedimentation of the solid components of the gray water during the night hours prevented. There is no breeding ground for Germs.

Da der Grauwasserspeicher in einer vorhandenen Sanitäreinrichtung, wie beispielsweise einer Dusch- oder Badewanne integriert ist, wird keine zusätzliche Aufstellfläche benötigt. Die erfindungsgemäße Wasserspareinrichtung kann in sehr kleinen Räumen untergebracht werden.Since the gray water tank in an existing sanitary facility, such as a shower or bathtub no additional footprint is required. The water saving device according to the invention can be very small Rooms.

Eine aufwendige Wartung der Wasserspareinrichtung ist nicht notwendig. Es reicht aus, den Grauwasserspeicher von Zeit zu Zeit zu öffnen und sauber zu wischen.Complicated maintenance of the water saving device is not necessary. It is enough to stop the gray water storage from time to time Time to open and wipe clean.

Eine Wasserspareinrichtung mit den vorgenannten Merkmalen ist deshalb sehr kostengünstig, weil es sich bei der Trittfläche um ein preisgünstiges Ergänzungsteil handelt, das einfach hergestellt und selbst von einem Laien angebracht werden kann. Erhebliche Kostenvorteile gegenüber dem Stand der Technik ergeben sich allein dadurch, daß die herkömmliche Duschwanne eines Badezimmers erhalten bleibt.A water saving device with the aforementioned features therefore very inexpensive, because it is the tread is an inexpensive accessory that is simple can be made and applied by a layperson. Significant cost advantages over the state of the art result solely from the fact that the conventional shower tray of a bathroom is preserved.

Die Wasserspareinrichtung kann mit minimalem Installationsaufwand in Betrieb genommen werden. Nach dem Duschen bleibt das Grauwasser einfach in der Duschwanne und wird nach und nach zur Spülung der Toilette verwendet. Sie eignet sich daher beispielsweise gut für einen Mieter, der in einem vorhandenen Badezimmer eine kostengünstige Wasserspareinrichtung betreiben möchte, ohne einen größeren Umbau durchzuführen. Die Oberseite der Duschwanne bildet eine obenliegende, großflächige Öffnung des Grauwasserspeichers, über die der Grauwasserspeicher zu Reinigungs- und Wartungszwecken sehr gut zugänglich ist.The water saving device can be installed with minimal installation effort be put into operation. That remains after showering Gray water simply in the shower tray and gradually becomes used to flush the toilet. It is therefore suitable For example, good for a tenant who lives in an existing one Bathroom operate an inexpensive water saving device would like to do without a major renovation. The top the shower tray forms a large, overhead opening of the gray water storage tank, via which the gray water storage tank is closed Cleaning and maintenance purposes is very accessible.

Besonders für die Verwendung der Wasserspareinrichtung in einem Mehrpersonenhaushalt ist es zweckmäßig, daß als Trittfläche für den Benutzer einen Einlegeboden mit wenigstens einer Abflußeinrichtung vorgesehen ist, über die das Grauwasser in den darunter liegenden, als Grauwasserspeicher fungierenden Teil der Duschwanne fließen kann. Auf diese Weise kommt ein Benutzer nicht mit dem gesammelten Grauwasser seines Vorgängers in Kontakt. Mit dieser Konstruktion können mehrere Personen nacheinander ihr Grauwasser in dem Grauwasserspeicher sammeln. Especially for the use of the water saving device in a multi-person household, it is appropriate that as a step for the user a shelf with at least a drainage device is provided, through which the gray water in the underlying, which act as gray water storage Part of the shower tray can flow. In this way a user does not come with the collected gray water of his Predecessor in contact. With this construction, several People consecutively their gray water in the gray water storage collect.

Um dem Benutzer durch das von anderen Personen verwendete und gesammelte Grauwasser kein unangenehmes Gefühl zu bereiten, versperrt die Abflußeinrichtung des Einlegebodens vorteilhafterweise die Sicht in den Grauwasserspeicher.To the user through that used and collected by other people Barred from making gray water uncomfortable the drain device of the shelf advantageously the View into the gray water reservoir.

Der Füllstand wird über den normalen Überlauf der Duschwanne begrenzt. Über diesen kann das Grauwasser abfließen, bevor es über den Rand der Duschwanne tritt.The fill level is above the normal overflow of the shower tray limited. The gray water can drain off over this before it steps over the edge of the shower tray.

Damit die Spülleitung nicht von der Oberseite der Duschwanne in den Grauwasserspeicher geführt werden muß, wodurch sie einen Schmutzfänger bilden würde und außerdem das Betreten der Duschwanne behindert, ist an dem Syphon der Duschwanne ein Syphonanschlußstück vorgesehen, an dem die Spülleitung angeschlossen ist. Das Syphonanschlußstück weist außerdem eine Abflußöffnung auf, die mit dem Abwassersystem des Gebäudes verbindbar ist. Über ein Überlaufrohr kann das Grauwasser, wenn es einen bestimmten Füllstand überschreitet, in das Abwassersystem des Gebäudes ablaufen.So that the flushing line does not come from the top of the shower tray must be led into the gray water storage, which makes them one Would form mud flaps and also entering the Shower tray is disabled, is on the siphon of the shower tray Siphon connector provided to which the flushing line is connected is. The siphon connector also has a Drain opening on that with the sewage system of the building is connectable. The gray water, if it exceeds a certain level, into the sewage system of the building.

In einer sich besonders für Neubauten eignenden Ausführung ist der Grauwasserspeicher als integrierter Speicher unterhalb der Duschwanne vorgesehen. Dieser besondere Grauwasserspeicher kann ein größeres Volumen als eine herkömmliche Duschwanne aufweisen. Es besteht die Möglichkeit, Grauwasserspeicher verschiedener Volumina herzustellen, die beispielsweise genau auf den Spülwasserbedarf einer Familie abgestimmt sind. Außerdem können Grauwasserspeicher bereits bei der Herstellung auf unterschiedliche bauliche Gegebenheiten abgestimmt werden.In a version that is particularly suitable for new buildings the gray water tank as an integrated tank below the Shower tray provided. This special gray water storage can have a larger volume than a conventional shower tray exhibit. There is a possibility of different gray water storage tanks Produce volumes that, for example, exactly the flushing water needs of a family are coordinated. Moreover can gray water storage tanks to different levels already during production structural conditions are coordinated.

Die Spülpumpe ist der Einfachheit halber in der Spülleitung zwischengeschaltet. Auf ihrer Saugseite ist die Spülpumpe mit dem Grauwasserspeicher und auf ihrer Druckseite mit dem Spülzulauf der Toilette verbunden.The rinsing pump is in the rinsing line for the sake of simplicity interposed. The rinsing pump is on its suction side the gray water tank and on its pressure side with the flushing inlet connected to the toilet.

Die Hygiene der Wasserspareinrichtung kann verbessert werden, wenn eine Desinfektionseinheit vorgesehen ist. In einer vorteilhaften Weiterbildung ist die Desinfektionseinheit dem Grauwasserspeicher vorgeschaltet, so daß der Grauwasserspeicher nur über die Desinfektionseinheit befüllbar ist. Auch wenn mehrere Sanitäreinrichtungen angeschlossen sind, die den Grauwasserspeicher speisen, reicht eine Desinfektionseinheit aus, um das gesamte zulaufende Grauwasser zu behandeln. Die Leistung der Desinfektionseinheit kann auf den individuellen Grauwasserdurchsatz einer Wasserspareinrichtung abgestimmt werden. Hierzu kann eine modular erweiterbare Desinfektionseinheit eingesetzt werden, die für den gewünschten Grauwasserdurchsatz ausgelegt wird. Alternativ kann die entsprechende Desinfektionseinheit aus einer Baureihe ausgewählt werden, deren Einheiten für unterschiedliche Grauwasserdurchsätze ausgelegt sind.The hygiene of the water saving device can be improved, if a disinfection unit is provided. In an advantageous Further training is the disinfection unit Gray water storage connected upstream, so that the gray water storage can only be filled via the disinfection unit. Also if several sanitary facilities are connected to the To feed the gray water tank, a disinfection unit is sufficient to treat all of the incoming gray water. The Performance of the disinfection unit can be based on the individual Gray water throughput of a water saving device coordinated become. A modularly expandable disinfection unit can be used for this are used for the desired gray water throughput is interpreted. Alternatively, the corresponding one Disinfection unit can be selected from a series, their units for different greywater throughputs are designed.

In einer alternativen Ausführungsform ist die Desinfektionseinheit dem Grauwasserspeicher nachgeschaltet. Das Grauwasser ist nur über die Desinfektionseinheit aus dem Grauwasserspeicher entnehmbar. Auf diese Weise wird das Grauwasser erst kurz bevor es zur Spülung der Toilette in den Spülzulauf der Toiletten gepumpt wird, entkeimt. Mit dieser Konstruktion kann man ausschließen, daß Keime, die sich während der Speicherung bilden in die Toilette gelangen.In an alternative embodiment, the disinfection unit downstream of the gray water tank. The gray water is only from the gray water tank via the disinfection unit removable. In this way, the gray water only becomes short before flushing the toilet in the flushing inlet of the toilets is pumped, sterilized. With this construction can one exclude that germs that are present during storage form get into the toilet.

Die beste Hygiene läßt sich erreichen, wenn sowohl eine vorgeschaltete als als auch eine nachgeschaltete Desinfektionseinheit vorgesehen ist.The best hygiene can be achieved if both upstream as well as a downstream disinfection unit is provided.

Vorzugsweise weist die Desinfektionseinheit eine Ultraviolettlampe auf, mit der durchströmendes Grauwasser entkeimbar ist. Selbstverständlich kann auch eine nach anderen Prinzipien arbeitende Desinfektionseinheit, wie beispielsweise eine Hochspannungsquelle, vorgesehen sein, um Keime abzutöten.The disinfection unit preferably has an ultraviolet lamp with which gray water flowing through can be sterilized. Of course, someone who works according to other principles can also Disinfection unit, such as a high voltage source, be provided to kill germs.
