Description

Die vorliegende Erfindung betrifft ein Dusch-WC, ein Verfahren zum Betreiben eines WC sowie die Verwendung eines Dusch-WC.The present invention relates to a shower toilet, a method for operating a toilet and the use of a shower toilet.

Wasserklosetts (WCs) mit einer Bidet-Funktion sind seit langer Zeit bekannt und im Einsatz. Hier ist ein WC zusätzlich mit zumindest einer Dusche zur Reinigung des Unterleibs eines Benutzers ausgestattet, die häufig kurz als Unterdusche bezeichnet wird. Beispielsweise kann ein motorisch-beweglicher Duscharm der Unterdusche auf eine Bedienungsoperation hin in die WC-Schüssel vorfahren und einen Duschwasserstrahl nach oben richten sowie nach Funktion zurückfahren. In vielen Fällen sind solche Duscheinrichtungen mit weiteren Einrichtungen ausgestattet, beispielsweise Warmwasserbereitern wie Boilern oder Durchlauferhitzern, Föhneinrichtungen, Duscharm-Reinigungseinrichtungen etc..Water closets (WCs) with a bidet function have been known and used for a long time. Here, a toilet is additionally equipped with at least one shower for cleaning the user's abdomen, which is often referred to as an under-shower for short. For example, a motorized, movable shower arm in the under-shower can move forward into the toilet bowl in response to an operating operation and direct a shower water jet upwards and move back according to function. In many cases, such shower facilities are equipped with other facilities, for example water heaters such as boilers or instantaneous water heaters, hair dryer facilities, shower arm cleaning facilities, etc.

Üblicherweise umfassen herkömmliche Duscharm-Reinigungseinrichtungen einen Spülwasserschlauch, mit dem im zurückgefahrenen Zustand des Duscharms Spülwasser tangential auf die Stirnfläche des Duscharms appliziert wird, um diesen zu reinigen. Eine solche herkömmliche Duscharm-Reinigungseinrichtung ist beispielweise in der DE 20 2012 001 170 U1 beschrieben.Conventional shower arm cleaning devices usually include a rinse water hose with which rinse water is applied tangentially to the end face of the shower arm when the shower arm is retracted in order to clean it. Such a conventional shower arm cleaning device is, for example, in DE 20 2012 001 170 U1 described.

  2. b. eine Sprühvorrichtung umfassend eine in dem Schüsselraum angeordnete Sprühdüse;
  • wobei die Sprühdüse zur Einnahme einer Ruheposition und einer Benutzungsposition angeordnet und ausgebildet ist, wobei vorzugsweise die Sprühdüse in der Benutzungsposition im Vergleich zu der Ruheposition weiter in den Schüsselraum hineinragt;
  • wobei die Sprühvorrichtung mit einer Wasserzufuhr und einer Desinfektionsmittelzufuhr versehen ist;
  • wobei während des Einnehmens der Ruheposition der Sprühdüse über die Desinfektionsmittelzufuhr ein Desinfektionsmittel förderbar ist.
A shower toilet, which contains toilet components, contributes to the fulfillment of at least one of the tasks according to the invention
  1. a. a toilet bowl surrounding a bowl space;
  2. b. a spray device comprising a spray nozzle arranged in the bowl space;
  • wherein the spray nozzle is arranged and designed to assume a rest position and a use position, the spray nozzle preferably protruding further into the bowl space in the use position compared to the rest position;
  • wherein the spray device is provided with a water supply and a disinfectant supply;
  • wherein a disinfectant can be conveyed via the disinfectant supply while the spray nozzle is in the rest position.

Das Erfindungsgemäße Dusch-WC zeichnet sich gegenüber den aus dem Stand der Technik bekannten Dusch-WCs mit einer Reinigungsfunktion des Duscharms dadurch aus, dass der Duscharm (Sprühdüse) in der Ruheposition nicht nur mit reinem Spülwasser, sondern zusätzlich auch mit einem Desinfektionsmittel besprüht und damit gereinigt wird. Aus diesem Grund umfasst die Sprühvorrichtung neben der aus dem Stand der Technik bekannten Wasserzufuhr zusätzlich eine Desinfektionsmittelzufuhr, wobei während des Einnehmens der Ruheposition der Sprühdüse über die Desinfektionsmittelzufuhr ein Desinfektionsmittel förderbar ist.The shower toilet according to the invention is distinguished from the shower toilets known from the prior art with a cleaning function of the shower arm in that the shower arm (spray nozzle) in the rest position is sprayed not only with pure rinse water, but also with a disinfectant and thus is cleaned. For this reason includes the spray device, in addition to the water supply known from the prior art, also has a disinfectant supply, with a disinfectant being able to be conveyed via the disinfectant supply while the spray nozzle is in the rest position.

Grundsätzlich können dabei das zur Reinigung der Sprühdüse vorgesehene Wasser und das Desinfektionsmittel getrennt voneinander über separate Auslässe auf die Stirnseite der Sprühdüse appliziert werden. In diesem Fall umfasst die Sprühvorrichtung einen separaten Wasserauslass und einen separaten Desinfektionsmittelauslass jeweils benachbart zur Stirnseite der Sprühdüse, über welche diese beiden Flüssigkeiten entweder zeitgleich oder nacheinander auf die Sprühdüse zum Zwecke der Reinigung bzw. Desinfektion aufgebracht werden. Bevorzugt ist es hingegen, dass das zur Reinigung der Sprühdüse vorgesehene Wasser und das Desinfektionsmittel nach vorherigem Vermischen auf die Stirnseite der Sprühdüse appliziert werden. In diesem Falle umfasst die Sprühvorrichtung einen Auslass benachbart zur Stirnseite der Sprühdüse, über den die Mischung aus Wasser und Desinfektionsmittel zum Zwecke der Reinigung bzw. Desinfektion aufgebracht wird.In principle, the water and the disinfectant intended for cleaning the spray nozzle can be applied separately from one another via separate outlets to the front side of the spray nozzle. In this case, the spray device comprises a separate water outlet and a separate disinfectant outlet, each adjacent to the front side of the spray nozzle, via which these two liquids are applied to the spray nozzle either simultaneously or one after the other for the purpose of cleaning or disinfection. However, it is preferred that the water intended for cleaning the spray nozzle and the disinfectant are applied to the front side of the spray nozzle after prior mixing. In this case, the spray device comprises an outlet adjacent to the front side of the spray nozzle, through which the mixture of water and disinfectant is applied for the purpose of cleaning or disinfection.

Erfindungsgemäß weist die Desinfektionsmittelzufuhr einen Desinfektionsmittelförderer auf, bei dem es sich um eine Pumpe handelt. Mittels einer solchen Pumpe ist es möglich, separat von der Wasserzufuhr das Desinfektionsmittel in die Sprühvorrichtung zu fördern und dann, vorteilhafterweise nach dem Vermischen mit dem zur Reinigung der Sprühdüse applizierten Wasser in einer separaten Mischvorrichtung, diese Komponenten in Form einer Mischung von außen auf die Stirnfläche der Sprühdüse zu applizieren. Es ist daher im Zusammenhang mit dieser besonderen Ausführungsform des erfindungsgemäßen Dusch-WC besonders bevorzugt, dass die Wasserzufuhr und die Desinfektionsmittelzufuhr über einen Mischer mit der Sprühdüse verbunden sind.According to the invention, the disinfectant supply has a disinfectant conveyor, which is a pump. By means of such a pump, it is possible to convey the disinfectant into the spray device separately from the water supply and then, advantageously after mixing with the water applied to clean the spray nozzle in a separate mixing device, to apply these components in the form of a mixture from the outside to the end face to apply using the spray nozzle. It is therefore particularly preferred in connection with this particular embodiment of the shower toilet according to the invention that the water supply and the disinfectant supply are connected to the spray nozzle via a mixer.

Neben dem Einsatz einer separaten Pumpe, mittels derer das Desinfektionsmittel in die Sprühvorrichtung gefördert wird, kann das Desinfektionsmittel auch durch Saugstrahl über die Wasserzufuhr in die Sprühvorrichtung gefördert werden, wobei in diesem Fall die Leitung, über welche das zur Reinigung der Sprühdüse applizierte Wasser zugeführt wird, als Saugstrahlpumpe fungiert.In addition to using a separate pump to pump the disinfectant into the spray device, the disinfectant can also be sprayed through the water supply using a suction jet are conveyed into the spray device, in which case the line through which the water applied to clean the spray nozzle is supplied acts as a suction jet pump.

Weiterhin ist es erfindungsgemäß, dass die Desinfektionsmittelzufuhr mit einem Desinfektionsmitteltank verbunden ist.Furthermore, it is according to the invention that the disinfectant supply is connected to a disinfectant tank.

Um das Desinfektionsmittel von außen auf die Sprühdüse zu applizieren, mündet die Desinfektionsmittelzufuhr in einem Desinfektionsmittelauslass, wobei der Desinfektionsmittelauslass vorzugsweise benachbart zur der Sprühdüse angeordnet ist. Werden zuvor, wie vorstehend beschrieben, das zur Reinigung der Sprühdüse vorgesehene Wasser und das Desinfektionsmittel als Mischung auf die Sprühdüse appliziert, so entspricht der Desinfektionsmittelauslass demjenigen Auslass, über den die Mischung aus Wasser und Desinfektionsmittel von außen auf die Sprühdüse appliziert wird.In order to apply the disinfectant to the spray nozzle from the outside, the disinfectant supply opens into a disinfectant outlet, the disinfectant outlet preferably being arranged adjacent to the spray nozzle. If, as described above, the water intended for cleaning the spray nozzle and the disinfectant are applied as a mixture to the spray nozzle, the disinfectant outlet corresponds to the outlet through which the mixture of water and disinfectant is applied to the spray nozzle from the outside.

Weiterhin ist es erfindungsgemäß bevorzugt, dass die die Wasserzufuhr oder die Desinfektionsmittelzufuhr oder beide einen Kunststoffschlauch aufweisen.Furthermore, according to the invention, it is preferred that the water supply or the disinfectant supply or both have a plastic tube.

Einen Beitrag zur Erfüllung mindestens einer der erfindungsgemäßen Aufgaben leistet auch ein Verfahren zum Betreiben eines WC, beinhaltend die Schritte

  1. A. Bereitstellen eines erfindungsgemäßen Dusch-WC;
  2. B. Betreiben des Dusch-WC in einem Gebäude.
A method for operating a toilet, including the steps, also contributes to the fulfillment of at least one of the tasks according to the invention
  1. A. Providing a shower toilet according to the invention;

Figur 1 zeigt das erfindungsgemäße Dusch-WC 1 mit Sprühdüse 5 in der Benutzungsposition 7 (Abbildung oben) und mit Sprühdüse 5 in der Ruheposition 6 (Abbildung unten). Das Dusch-WC umfasst eine WC-Schüssel 2 mit einem Schüsselraum 3, in den die Sprühdüse 5 in der Benutzungsposition 7 hineinragt (Abbildung oben in der Figur 1). In der Ruheposition 6 ist die Sprühdüse 5 nahezu vollständig in die WC-Schüssel 3 eingefahren (Abbildung unten in der Figur 1). Dieses Dusch-WC entspricht in seiner Grundanordnung denjenigen Dusch-WCs mit Reinigungsfunktion, die aus dem Stand der Technik bekannt sind. Figure 1 shows the shower toilet 1 according to the invention with spray nozzle 5 in the use position 7 (picture above) and with spray nozzle 5 in the rest position 6 (picture below). The shower toilet includes a toilet bowl 2 with a bowl space 3, into which the spray nozzle 5 protrudes in the use position 7 (illustration above in the Figure 1 ). In the rest position 6, the spray nozzle 5 is almost completely retracted into the toilet bowl 3 (illustration below in the Figure 1 ). This shower toilet corresponds in its basic arrangement to those shower toilets with a cleaning function that are known from the prior art.

Figur 2 zeigt nun eine Seitenansicht einer aus dem Dusch-WC ausgebauten Sprühvorrichtung 4 mit Reinigungsfunktion umfassend eine röhrenförmigen und verschiebbar angeordnete Sprühdüse 5 in der Ruheposition 7. Zu erkennen ist eine Wasserzufuhr 8, über die Wasser in die Sprühvorrichtung 4 einströmt, um in dieser die Sprühdüse 5 über einen Auslass 12 (siehe Figur 3) an der Stirnseite zu reinigen. Über eine Desinfektionsmittelzufuhr 9 wird aus einem Desinfektionsmitteltank 13 nun ein Desinfektionsmittel in die Sprühvorrichtung 4 eingebracht. Wie in der Figur 2 gezeigt, erfolgt das Einbringen des Desinfektionsmittels über die Leitung des Spülwassers, die als Saugstrahlpumpe fungiert. Die so erhaltene Mischung aus Wasser und Desinfektionsmittel wird nun über den Desinfektionsmittelauslass 12 (siehe Figur 3) auf die Stirnseite der Sprühdüse 5 appliziert, um diese von außen zu reinigen und insbesondere auch zu desinfizieren. Denkbar ist auch, das Desinfektionsmittel über eine separate Pumpe (in Figur 2 nicht gezeigt) zu fördern und gegebenenfalls über einen separaten weiteren Auslass (in Figur 2 ebenfalls nicht gezeigt) getrennt vom Wasser auf die Stirnseite der Sprühdüse 5 zu applizieren. Weiterhin kann an dem Ende der Sprühvorrichtung 4, die dem Schüsselraum 3 zugewandt ist, eine Abdeckung 14 vorgesehen sein. Die Abdeckung 14 ist verschlossen, d.h. sie schließt im Wesentlichen bündig mit dem Schüsselraum 3 ab, wenn die Sprühdüse 5 sich in Ruheposition befindet. Figure 2 now shows a side view of a spray device 4 removed from the shower toilet with a cleaning function, comprising a tubular and displaceably arranged spray nozzle 5 in the rest position 7. A water supply 8 can be seen, via which water flows into the spray device 4 in order to create the spray nozzle 5 in it via an outlet 12 (see Figure 3 ) to be cleaned on the front side. A disinfectant is now introduced into the spray device 4 from a disinfectant tank 13 via a disinfectant supply 9. Like in the Figure 2 shown, the disinfectant is introduced via the rinsing water line, which acts as a suction jet pump. The resulting mixture of water and disinfectant is now via the disinfectant outlet 12 (see Figure 3 ) is applied to the front side of the spray nozzle 5 in order to clean it from the outside and in particular to disinfect it. It is also conceivable to supply the disinfectant via a separate pump (in Figure 2 not shown) and, if necessary, via a separate additional outlet (in Figure 2 also not shown) to be applied separately from the water to the front side of the spray nozzle 5. Furthermore, a cover 14 can be provided at the end of the spray device 4, which faces the bowl space 3. The cover 14 is closed, ie it is essentially flush with the bowl space 3 when the spray nozzle 5 is in the rest position.

Figur 3 zeigt die Aufsicht auf den in Figur 2 mit einem fett gedruckten Pfeil mit der Abdeckung 14 verschlossenen Bereichs der Sprühvorrichtung 4. wenn die Abdeckung 14 verschlossen ist, bildet sich eine Spielkammer 15 die einen Düsenauslass 16 der Düse 5 sowie ein Desinfektionsmittelauslass 12 aufweist. Figure 3 shows the supervision on the in Figure 2 with a bold arrow with the cover 14 closed area of the spray device 4.
