SPULVORRICHTUNG EINER TOILETTENANLAGE MIT SPULARM ZUM AUSSPULEN EINER TOILETTEN SCHÜSSELSPOOL DEVICE OF A TOILET SYSTEM WITH SPOOL ARM FOR RINSING A TOILET BOWL
Die Erfindung betrifft eine Spülvorrichtung einer Toilettenanlage, mit einer Toilettenschüssel, die in einem unteren Bereich eine Öffnung aufweist, an die eine Entsorgungsleitung anzu- schliessen ist und mit Mitteln zum Ausspülen der Innenseite der Toilettenschüssel mit Wasser.The invention relates to a flushing device of a toilet system, with a toilet bowl which has an opening in a lower region to which a disposal line is to be connected and with means for rinsing the inside of the toilet bowl with water.
SpülVorrichtungen der genannten Art sind allgemein bekannt. Bei einer weit verbreiteten Ausführung weist die Spülvorrichtung im Rand der Toilettenschüssel einen Spülkanal auf, der an einen Spülkasten angeschlossen ist. Zur Spülung wird der Spülkasten betätigt und Spülwasser gelangt in den Spülkanal und von diesem durch Öffnungen auf die Innenseite der Klosettschüssel. Das Wasser rinnt entlang dieser Innenseite nach unten in die AblaufÖffnung. Hierbei wird die Klosettschüssel gereinigt. Verbesserungen beim Spülkasten als auch bei der Toilettenschüssel haben dazu geführt, dass mit vergleichsweise wenig Wasser gespült und die Toilettenschüssel gereinigt werden kann. Grundsätzlich besteht aber weiterhin das Bedürfnis, den Spülwasserverbrauch für Toilettenanlagen noch weiter zu verringern.Flushing devices of the type mentioned are generally known. In a widely used embodiment, the flushing device has a flushing channel in the edge of the toilet bowl, which is connected to a flushing cistern. The flushing cistern is actuated for flushing and flushing water enters the flushing channel and from there through openings to the inside of the toilet bowl. The water runs down this inside into the drain opening. Here, the toilet bowl is cleaned. Improvements in the cistern as well as in the toilet bowl have resulted in that relatively little water can be flushed and the toilet bowl can be cleaned. In principle, however, there is still a need to reduce the flushing water consumption for toilet facilities even further.
Der Erfindung liegt die Aufgabe zugrunde, eine SpülVorrichtung der genannten Art zu schaffen, die mit geringerem Wasserverbrauch dennoch eine effiziente Reinigung der Toilettenschüssel ermöglicht. Die Aufgabe ist gemass Anspruch 1 gelöst. Bei einer erfindungsgemässen SpülVorrichtung ist zur Reinigung der Toilettenschüssel ein ausfahrbarer Spülarm vorgesehen, mit dem die Innenseite der Toilettenschüssel mit Wasser ausspülbar ist. Mit dem Spülarm kann gezielt Wasser gegen die Innenseite der Toilettenschüssel gespritzt und damit diese gereinigt werden. Das Wasser kann gezielt gegen die kritischen Bereiche der Schüsselinnenseite gerichtet werden. Damit ist mit geringem Wasserverbrauch eine effiziente Reinigung der Toilettenschüssel -mög- lieh.The invention has for its object to provide a flushing device of the type mentioned, which nevertheless enables efficient cleaning of the toilet bowl with lower water consumption. The object is achieved in accordance with claim 1. In a flushing device according to the invention, an extendable flush arm is provided for cleaning the toilet bowl, with which the inside of the toilet bowl can be flushed out with water. With the rinse arm, water can be targeted against the inside of the Injected toilet bowl and cleaned them. The water can be directed against the critical areas of the inside of the bowl. Efficient cleaning of the toilet bowl is thus possible with low water consumption.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Spülarm bewegbar ist. Dadurch ist es möglich, den Spülarm noch gezielter gegen die zu reinigenden Stellen der Toilettenschüsse- linnenseite zu richten. Dadurch ist eine noch effizientere Reinigung bei geringem Wasserverbrauch möglich.According to a development of the invention, it is provided that the flushing arm can be moved. This makes it possible to direct the flush arm even more specifically against the areas of the inside of the toilet bowl to be cleaned. This enables even more efficient cleaning with low water consumption.
Die genannte Bewegbarkeit umfasst insbesondere eine Bewegung in Längsrichtung des Spülarmes, eine Drehung um die Längsrichtung des Spülarmes sowie eine Schwenk- oder Kreisbewegung. Denkbar sind auch Kombinationen der genannten Bewegungen. Dadurch kann insbesondere eine besondere Formgebung der Toilettenschüssel berücksichtigt werden.The mentioned mobility includes in particular a movement in the longitudinal direction of the washing arm, a rotation about the longitudinal direction of the washing arm and a swiveling or circular movement. Combinations of the movements mentioned are also conceivable. In this way, in particular a special shape of the toilet bowl can be taken into account.
Nach einer Weiterbildung der Erfindung ist der Spülarm in eine Unterdusche integriert oder zusätzlich zur ünterdusche vorgesehen. Dadurch ist es möglich, die Wasserzufuhr für die ünterdusche sowie die Steuerung gleichzeitig auch zur Reinigung der Toilettenschüssel zu verwenden.According to a further development of the invention, the flushing arm is integrated in an under-shower or provided in addition to the under-shower. This makes it possible to use the water supply for the sub-shower and the control unit to clean the toilet bowl at the same time.

Die Fig..1 bis 3 zeigen eine Toilettenanlage 1, die eine Schüssel 5 aufweist, die beispielsweise aus Stahlblech oder Keramik hergestellt ist. Eine in einem hinteren Bereich 7ä vergleichsweise steile Innenseite 7 ist an einem unteren Ende mit einem Absaugkänal 6 verbunden, an dem eine Absaugvorrichtung 25 angeschlossen ist. Die Absaugvorrichtung 25 weist hier nicht gezeigte Mittel, beispielsweise eine Pumpe auf, mit der im Saugkanal 6 ein Unterdruck erzeugt werden kann. Die Schüssel 5 ist in Draufsicht etwa pilzför ig ausgebildet und besitzt einen oberen Rand 5a, an dem als Sitzgelegenheit 2 Platten 8, sogenannte Pads, befestigt sind.1 to 3 show a toilet system 1 which has a bowl 5 which is made, for example, of sheet steel or ceramic. A comparatively steep inside 7a in a rear region 7a is connected at a lower end to a suction channel 6, to which a suction device 25 is connected. The suction device 25 has means not shown here, for example a pump, with which a negative pressure can be generated in the suction channel 6. The bowl 5 is approximately mushroom-shaped in plan view and has an upper edge 5a, to which 2 plates 8, so-called pads, are attached as seating.
Im oberen Bereich einer Rückwandung 5b der Schüssel 5 ist in einer Ausnehmung 5c der Schüssel 5 ein Spülarm 9 gelagert, der wie ersichtlich schräg nach vorne in die Schüssel 5 hineinragt. Der Spülarm 9 ist mit einem hier nicht näher gezeigten Antrieb 23 in den Richtungen des Doppelpfeils 17 als auch in den Richtungen des Doppelpfeils 18 bewegbar. Ferner ist der Spülarm 9 an eine Wasserleitung 24 angeschlossen. Der Spülarm 9 besitzt zwei Funktionen. Er dient einerseits als ünterdusche zur Körper einigung und weist hierzu an einem vorderen Kopf 9a nach oben gerichtete Düsen 19 auf, durch die ein nach oben gerichteter WasserstrahlIn the upper region of a rear wall 5b of the bowl 5, a flushing arm 9 is mounted in a recess 5c of the bowl 5 and, as can be seen, protrudes obliquely forward into the bowl 5. The rinsing arm 9 is equipped with a drive 23 not shown here the directions of the double arrow 17 and in the directions of the double arrow 18 movable. Furthermore, the rinsing arm 9 is connected to a water line 24. The flush arm 9 has two functions. It serves on the one hand as a sub-shower for body unification and has for this purpose on a front head 9a upwardly directed nozzles 19 through which an upward water jet
51 gebildet werden kann. Die Verwendung und Ausbildung eines Spülarmes 9 als Unterdusche ist an sich bekannt. Es wird hierzu auf die WO 02/22971 AI verwiesen. Der Spülarm 9 dient gleichzei- tig zur Reinigung der Innenfläche 7 der Klosettschüssel 5. Hierzu weist der Kopf 9a an seiner Unterseite nach unten gerichtete Düsen 29 auf, mit denen ein nach unten gerichteter Wasserstrahl51 can be formed. The use and design of a flush arm 9 as a shower is known per se. For this purpose, reference is made to WO 02/22971 AI. The rinsing arm 9 serves at the same time for cleaning the inner surface 7 of the toilet bowl 5. For this purpose, the head 9a has on its underside directed nozzles 29 with which a water jet directed downwards
52 erzeugbar ist. Der Spülarm 9 dient somit gleichzeitig zur Körperreinigung und zur Reinigung der Schüssel 5. Diese beiden Funktionen werden zeitlich nacheinander ausgeführt. In einem ersten Zyklus erfolgt die Kδrperreinigung mit dem Wasserstrahl Sl. In einem zweiten Zyklus wird die Schüssel 5 mit dem Wasserstrahl S2 gereinigt . In einem dritten Zyklus erfolgt in an sich bekannter Weise die Trocknung des Körpers mit Warmlust. Hier kann ebenfalls in an sich bekannter Weise der Spülarm 9 verwendet werden. Ebenfalls ist hier ein Trocknen der Schüssel 5 mittels Warmluft möglich. Geeignete Mittel zur Erzeugung von Warmluft sind dem Fachmann bekannt. Es wird hier zudem auf die genannte WO 02/22971 AI verwiesen. In diesem dritten Zyklus kann eben- falls ein hier nicht gezeigter Geruchsverschluss nachgefüllt werden. Dies erfolgt ebenfalls mit dem nach unten gerichteten Wasserstrahl S2. Die genannten Zyklen werden vorzugsweise mit einem automatischen Programm gesteuert; hierbei können Parameter, vorzugsweise die Spülseiten optimiert eingestellt werden.52 can be generated. The rinsing arm 9 is thus used for body cleaning and for cleaning the bowl 5 at the same time. These two functions are carried out in succession. In a first cycle, the body is cleaned with the water jet S1. In a second cycle, the bowl 5 is cleaned with the water jet S2. In a third cycle, the body dries with warmth in a manner known per se. The rinse arm 9 can also be used here in a manner known per se. Drying of the bowl 5 by means of warm air is also possible here. Suitable means for generating warm air are known to the person skilled in the art. Reference is also made here to the aforementioned WO 02/22971 AI. In this third cycle, an odor trap (not shown here) can also be refilled. This is also done with the water jet S2 directed downwards. The cycles mentioned are preferably controlled with an automatic program; here parameters, preferably the rinsing sides, can be set in an optimized manner.
Die Fig. 1 bis 3 zeigen den Spülarm 9 in einer Arbeitsstellung, in welcher er ausgefahren ist. In der Ruhestellung ist der Spülarm 9 im Wesentlichen vollständig in die Ausnehmung 5c eingefah- ren. Zur Reinigung des Beckens 5 ist der Spülarm 9 in der gezeigten ausgefahrenen Position in den Richtungen des , Doppelpfeils 18 um seine Längsachse bewegbar. Bei dieser Bewegung wird der Wasserstrahl S2 entsprechend verschwenkt. Hierbei wird die Innenseite 7 gründlich gewaschen und die abgespülten Rückstände werden in den Saugkanal 6 ' geschwemmt. Durch Erzeugen eines Unterdruckes im Saugkanal 6 können das Wasser und die weggespülten Bestandteile abgesogen werden. Dies kann gegebenenfalls mehrfach wiederholt werden. Der Wasserstrahl S2 ist ein Druckstrahl, wo- bei der Druck höher sein kann als derjenige des Wasserstrahls Sl. Zur Erhöhung der ReinigungsWirkung kann die Temperatur des Wasserstrahls S2 erhöht sein. Denkbar ist auch die Zugabe von Reinigungs- und/oder Duftmitteln.1 to 3 show the rinsing arm 9 in a working position in which it is extended. In the rest position, the flushing arm 9 is essentially completely retracted into the recess 5c. Ren. For cleaning the basin 5, the rinsing arm 9 is movable in the extended position shown in the directions of the double arrow 18 about its longitudinal axis. During this movement, the water jet S2 is pivoted accordingly. Here, the inside 7 is washed thoroughly and the rinsed-off residues are washed into the suction channel 6 '. By generating a negative pressure in the suction channel 6, the water and the components washed away can be drawn off. If necessary, this can be repeated several times. The water jet S2 is a pressure jet, whereby the pressure can be higher than that of the water jet S1. In order to increase the cleaning effect, the temperature of the water jet S2 can be increased. The addition of cleaning agents and / or fragrances is also conceivable.
Die Fig. 4 bis 6 zeigen eine Toilettenanlage 2, die sich von der Toilettenanlage 1 durch einen anderen Spülarm 10 unterscheidet. Dieser Spülarm 10 ist ebenfalls als Unterdusche verwendbar und besitzt einen Kopf 10a, mit dem ein nach oben gerichteter Wasserstrahl S3 erzeugbar ist. Zur Reinigung des Beckens 5 ist der Kopf 10a mit nach unten gerichteten Düsen 10b als auch mit nach vorne gerichteten Düsen 10c versehen. Mit den Düsen 10a und 10c ist ein Wasserstrahl S4 erzeugbar, der nach unten als auch nach vorne gerichtete Sprühstrahlen besitzt. Damit möglichst die gesamte Innenfläche 7 besprüht werden kann, ist der Spülarm .10 in den Richtungen des Doppelpfeils 21 hin und her schwenkbar.4 to 6 show a toilet system 2, which differs from the toilet system 1 by a different flush arm 10. This flushing arm 10 can also be used as a shower and has a head 10a with which an upward water jet S3 can be generated. To clean the basin 5, the head 10a is provided with downwardly directed nozzles 10b and with forwardly directed nozzles 10c. With the nozzles 10a and 10c, a water jet S4 can be generated, which has downward and forwardly directed spray jets. So that the entire inner surface 7 can be sprayed as far as possible, the flushing arm .10 can be pivoted back and forth in the directions of the double arrow 21.
Gleichzeitig ist der Spülarm 10 in den Richtungen des Doppel- pfeils 22 um seine Längsachse schwenkbar. Die Bewegungen gemass den Doppelpfeilen 21 und 22 sind gesteuert und so eingestellt, dass die Innenfläche 7 optimal besprüht wird. Der Reinigungs o - gang ist zeitlich gesteuert und kann wiederholt werden. Auch bei der Toilettenanlage 2 werden vorzugsweise die oben genannten drei Zyklen durchgeführt. Die in den Fig. 7 und 8 gezeigte Toilettenanlage 3 weist einen Duscharm 11 und zwei parallel zum Duscharm 11 verlaufende Spül- arme 12 auf. Der Duscharm 11 besitzt einen Kopf 11a mit ledig- lieh nach oben gerichteten Düsenöffnungen 30 auf, mit denen ein nach oben gerichteter Duschstrahl S5 erzeugbar ist. Die beiden seitlich neben dem Duscharm 11 angeordneten Spülarme 12 weisen jeweils einen Kopf 12a mit hier nicht gezeigten nach unten gerichteten Düsenöffnungen auf, mit denen jeweils ein nach unten gerichteter Wasserstrahl 36 erzeugbar ist. Die beiden Spülarme 12 sind jeweils um ihre Längsachse in den Richtungen des Doppelpfeils 26 verschwenkbar. Hierbei werden die beiden Wasserstrahlen S6 entsprechend verschwenkt und sprühen die Innenseite 7 des Beckens 5 ab. Die beiden Köpfe 12a können zudem nach vorne ge- richtete Düsenöffnungen aufweisen, wie dies beim Kopf 10a der Fall ist . Der Duscharm 11 und die beiden Spülarme 12 sind in den Fig. 7 und 8 in der Arbeitsstellung gezeigt. Zur Reinigung des Körpers wird zuerst der Duscharm 11 ausgefahren und mit diesem wird der Körper gereinigt und getrocknet. Zur Reinigung der in- nenseite 7 wird der Duscharm 11 in die Ruhestellung zurückgefahren und gleichzeitig werden die beiden Spülarme ausgefahren und zur Reinigung der Innenseite 7 wie erwähnt verschwenkt. Nach der Reinigung der Innenfläche 7a und gegebenenfalls nach dem Nachfüllen des hier nicht gezeigten Geruchsverschlusses werden die beiden Spülarme 12 wieder in die Ruhestellung zurückgefahren. Bei der Reinigung der Schüssel 5 ist der Duscharm 11 somit versenkt und kann nicht verschmutzt werden. Dies ist aus hygienischen Gründen sehr vorteilhaft.At the same time, the rinsing arm 10 can be pivoted about its longitudinal axis in the directions of the double arrow 22. The movements according to the double arrows 21 and 22 are controlled and adjusted so that the inner surface 7 is sprayed optimally. The cleaning process is timed and can be repeated. The above-mentioned three cycles are also preferably carried out in the toilet installation 2. The toilet system 3 shown in FIGS. 7 and 8 has a shower arm 11 and two washing arms 12 running parallel to the shower arm 11. The shower arm 11 has a head 11a with only borrowed upward nozzle openings 30, with which an upward directed shower jet S5 can be generated. The two rinsing arms 12 arranged laterally next to the shower arm 11 each have a head 12a with downwardly directed nozzle openings, not shown here, with which a downward water jet 36 can be generated in each case. The two rinsing arms 12 can each be pivoted about their longitudinal axis in the directions of the double arrow 26. Here, the two water jets S6 are pivoted accordingly and spray the inside 7 of the basin 5. The two heads 12a can also have forwardly directed nozzle openings, as is the case with head 10a. The shower arm 11 and the two rinsing arms 12 are shown in FIGS. 7 and 8 in the working position. To clean the body, the shower arm 11 is first extended and the body is cleaned and dried with it. To clean the inside 7, the shower arm 11 is moved back into the rest position and at the same time the two rinsing arms are extended and pivoted for cleaning the inside 7 as mentioned. After cleaning the inner surface 7a and, if necessary, after refilling the odor trap, which is not shown here, the two rinsing arms 12 are moved back into the rest position. When cleaning the bowl 5, the shower arm 11 is thus sunk and cannot be contaminated. This is very advantageous for hygienic reasons.
Die in den Fig. 9 bis 11 gezeigte Toilettenanlage 4 weist einen Spülarm 13 auf, der einen kugelförmigen Kopf 14 besitzt, der in den Richtungen der Doppelpfeile 16 um seinen Mittelpunkt rotierbar ist. Der Kopf 14 ist an seiner Mantelfläche mit einer Mehr- zahl von Düsenöffnungen 31 versehen, mit denen ein nach oben gerichteter Duschsträhl S7, ein nach vorne gerichteter Reinigungsstrahl S8 sowie ein nach unten gerichteter Reinigungsstrahl S9 erzeugbar- sind.' . Die genannte kugelkopfartigen Bewegungen des- Kopfes 14 werden vorzugsweise lediglich zur Reinigung. ' der Innenseite 7 ausgeführt. Zur Reinigung des Körpers wird der Kopf 14 vorzugsweise nicht bewegt. Grundsätzlich kann er hierbei jedoch auch eine geeignete Bewegung ausführen.The toilet system 4 shown in FIGS. 9 to 11 has a flush arm 13 which has a spherical head 14 which can be rotated about its center in the directions of the double arrows 16. The head 14 is provided with a multiple Number of nozzle openings 31 provided, with which an upward directed shower jet S7, a forwardly directed cleaning jet S8 and a downwardly directed cleaning jet S9 can be generated. ' . The mentioned head-like movements of the head 14 are preferably only for cleaning . ' the inside 7 executed. The head 14 is preferably not moved to clean the body. In principle, however, he can also perform a suitable movement.
Bei den oben beschriebenen Toilettenanlagen 1, 2, 3 und 4 ist jeweils eine Körperreinigung sowie eine Reinigung der Schüssel 5 vorgesehen. Grundsätzlich ist hier aber die Reinigung der Schüssel 5 in erster Linie wesentlich und die Körperreinigung kann grundsätzlich auch weggelassen werden. So kann beispielsweise bei der Toilettenanlage 3 der Duscharm 11 grundsätzlich auch weggelassen werden. Die Schüssel 5 ist vorzugsweise eine Klosettschüssel, grundsätzlich kann sie jedoch auch eine Schüssel für ein Urinal sein. Der bei üblichen Toilettenanlagen vorgesehene Spülkanal und auch einen Spülkasten sind bei den Toiletten- anlagen 1 bis 4 nicht erforderlich, jedoch grundsätzlich nicht ausgeschlossen. Anstelle des Absaugkanaies 6 kann grundsätzlich auch ein üblicher Siphon vorgesehen sein. Eine Absaugung mit Unterdruck ist hier jedoch aufgrund des geringen Wasserverbrauches bevorzugt . In the above-described toilet facilities 1, 2, 3 and 4, body cleaning and cleaning of the bowl 5 are provided. Basically, the cleaning of the bowl 5 is primarily essential here and the body cleaning can also be omitted in principle. For example, in the case of the toilet system 3, the shower arm 11 can in principle also be omitted. The bowl 5 is preferably a toilet bowl, but in principle it can also be a bowl for a urinal. The flushing channel provided in conventional toilet systems and also a cistern are not necessary for the toilet systems 1 to 4, but are in principle not excluded. Instead of the suction channel 6, a conventional siphon can in principle also be provided. Suction with negative pressure is preferred here due to the low water consumption.
