Description

Die vorliegende Erfindung betrifft einen Spülwasserverteiler für ein Toilettenbecken, insbesondere betrifft die vorliegende Erfindung einen Spülwasserverteiler für ein Toilettenbecken ohne Spülrand.The present invention relates to a Spülwasserverteiler for a toilet bowl, in particular, the present invention relates to a Spülwasserverteiler for a toilet bowl without flushing edge.

Stand der TechnikState of the art

Die Spülung eines Toilettenbeckens kann über einen Spülkasten oder ein Druckspülsystem erfolgen. In jedem Fall werden an die zu erfolgende Spülung des Toilettenbeckens gemäß europäischer Norm E-N 997 diverse Anforderungen gestellt. Unter anderem muss eine flächige Ausspülung der Innenschale gewährleistet sowie ein Austreten von Spritzern (Überspritzen) vermieden werden. Diese Forderungen führen insbesondere bei Toilettenbecken ohne Spülrand zu einer erhöhten Anforderung an die Präzision bestimmter Bauteile wie beispielsweise dem Spülwasserverteiler.The flushing of a toilet bowl can be done via a cistern or a Druckspülsystem. In any case, various requirements are placed on the flushing of the toilet bowl in accordance with European standard E-N 997. Among other things, a surface rinsing of the inner shell must be ensured and spillage (overspray) should be avoided. These requirements lead in particular in toilet bowl without flushing edge to increased demands on the precision of certain components such as the rinse water distributor.

Ein besonderes Problem besteht darin, dass Toilettenbecken beispielsweise im Falle einer Nachrüstung mit unterschiedlichen Spülkästen verwendet werden, die ihrerseits unterschiedliche Spülströme aufweisen. So weisen ältere Spülkästen regelmäßig Spülströme im Bereich von 3 Litern je Sekunde und neuere Spülkästen Spülströme von 2 bis 2,4 Litern je Sekunde auf. Es hat sich daher insbesondere bei WCs ohne Spülrand problematisch gezeigt, dass aufgrund der unterschiedlichen Spülströme ein Überspritzen besonders leicht auftreten kann, da der Spülrand höhere Spülströme besser abfangen kann. Um dies, insbesondere bei Toilettenbecken ohne Spülrand, zu vermeiden, ist es herkömmlicherweise bekannt, in das jeweilige Toilettenbecken einen an den Spülstrom des jeweiligen Spülkastens angepassten Spülwasserverteiler einzusetzen. Dies macht es jedoch nachteilhafterweise erforderlich, für ein entsprechendes (spülrandloses) Toilettenbecken eine Vielzahl unterschiedlicher Spülwasserverteiler am Markt vorzuhalten, damit der jeweils passende Spülwasserverteiler entsprechend des Spülstroms des Spülkastens zum Einbau gelangen kann, wodurch ein Überspritzen vermieden werden kann. Hierdurch steigen die Produktionskosten des Toilettenbeckens.A particular problem is that toilet bowls are used, for example, in the case of retrofitting with different cisterns, which in turn have different flushing currents. For example, older flushing cisterns regularly have flushing flows in the range of 3 liters per second, and newer flushing cisterns have flushing flows of 2 to 2.4 liters per second. It has therefore been particularly problematic in WCs without flushing edge that due to the different flushing currents overspray can occur particularly easily, since the flushing rim can better catch higher flushing currents. To avoid this, especially in toilet bowl without flushing rim, it is conventionally known to use in the respective toilet bowl adapted to the flushing flow of the respective cistern flushing water distributor. However, this disadvantageously makes it necessary to provide a large number of different rinsing water distributors on the market for a corresponding (rimless) toilet bowl so that the respectively appropriate rinsing water distributor can be installed in accordance with the rinsing flow of the cistern, whereby overspray can be avoided. This increases the production costs of the toilet bowl.

Es ist daher Aufgabe der vorliegenden Erfindung einen Spülwasserverteiler für ein Toilettenbecken, insbesondere einen Spülwasserverteiler für ein Toilettenbecken ohne Spülrand anzugeben, das die vorgenannten Nachteile des Standes der Technik überwindet.It is therefore an object of the present invention to provide a Spülwasserverteiler for a toilet bowl, in particular a Spülwasserverteiler for a toilet bowl without flushing edge, which overcomes the aforementioned disadvantages of the prior art.

Offenbarung der ErfindungDisclosure of the invention

Gemäß einem ersten Aspekt der Erfindung einen Spülwasserverteiler offenbart, der die Merkmale des Anspruchs 1 aufweist.According to a first aspect of the invention, there is disclosed a rinse water dispenser having the features of claim 1.

Es ist somit erfindungsgemäß möglich, eine dem Spülstrom des Spülkastens angepasste Spülstromdrossel in den Spülwasserverteiler einzusetzen, und diese Spülstromdrossel bei Bedarf (beispielsweise Wechsel des Spülkastens) gegen eine andere Spülstromdrossel auszutauschen. Mit anderen Worten ist es möglich, unterschiedliche Spülstromdrosseln (mit unterschiedlich starker Spülstromdrosselwirkung) im Spülwasserverteiler dauerhaft, jedoch lösbar zu fixieren bzw. zu verriegeln (bei Bedarf) und aus dem Spülwasserverteiler wieder zu entfernen, ohne den Spülwasserverteiler hierbei zu beschädigen. Gemäß einem Aspekt der Erfindung ist es sogar möglich, den Spülwasserverteiler in der bestimmungsgemäßen Position innerhalb des Toilettenbeckens zu belassen und die Spülstromdrossel in dieser bestimmungsgemäßen Position zu tauschen.It is thus possible according to the invention to use a rinsing flow throttle adapted to the flushing flow of the flushing cistern in the flushing water distributor, and to exchange this flushing flow restrictor if necessary (for example, change of the cistern) for another flushing flow restrictor. In other words, it is possible to permanently or detachably fix or lock different purge flow restrictors (with differently strong purge flow throttling effect) in the purge water manifold in the purge water manifold (if required) and remove them from the purge water manifold without damaging the purge water manifold. According to one aspect of the invention, it is even possible to leave the flushing water distributor in the intended position within the toilet bowl and to exchange the flushing flow restrictor in this intended position.

Das Fixierungsmittel des Spülwasserverteilers ist ausgebildet, die Spülstromdrossel lösbar, jedoch dauerhaft im Spülwasserverteiler zu fixieren bzw. zu verriegeln. In einer besonders bevorzugten Ausführungsvariante ist das Fixierungsmittel durch einen Rastmechanismus ausgebildet, wobei vorzugsweise ein Haken oder eine Nut der Spülstromdrossel formschlüssig (und/oder kraftschlüssig) in eine korrespondierende Ausnehmung im Spülwasserverteiler eingreift.The fixing means of the flushing water distributor is designed to releasably but permanently fix the flushing flow restrictor in the flushing water distributor or to lock. In a particularly preferred embodiment, the fixing means is formed by a latching mechanism, wherein preferably a hook or a groove of the flushing flow throttle positively (and / or non-positively) engages in a corresponding recess in the flushing water manifold.

Vorzugsweise ist das Toilettenbecken ein Toilettenbecken ohne Spülrand. Ein Toilettenbecken ohne Spülrand ist im Sinne der vorliegenden Erfindung ein Toilettenbecken, bei dem eine Auflage für einen Toilettensitz keinen über den gesamten Umfang verlaufenden Überstand oder Überhang (sogenannter Spülrand) aufweist, der den oberen Rand der Innenschale nach innen überragt. Es ist offensichtlich, dass das Spülwasser in einem bestimmten Bereich der Innenschale in das Toilettenbecken eingespeist werden muss, wobei dieser Bereich zur Vermeidung von Spritzern einen Überhang aufweisen kann. Jedoch beträgt ein solcher Überhang vorzugsweise kleiner als 30 %, besonders bevorzugt kleiner als 10 % des Umfangs der Auflage für den Toilettensitz.Preferably, the toilet bowl is a toilet bowl without flushing edge. A toilet bowl without flushing rim is in the context of the present invention, a toilet bowl, in which a support for a toilet seat over the entire circumference extending overhang or overhang (so-called flushing edge), which has the upper edge of the Inner shell protruding inwards. It is obvious that the rinse water must be fed into the toilet bowl in a certain area of the inner shell, whereby this area may have an overhang to avoid splashes. However, such an overhang is preferably less than 30%, more preferably less than 10%, of the circumference of the rest for the toilet seat.

Weiterhin ist es bevorzugt, dass der Spülwasserverteiler einen länglichen Grundkörper aufweist, wobei der Grundkörper durch einen offenen Hohlzylinder ausgebildet ist. Weiterhin weist der Grundkörper vorzugsweise ein ringförmiges Halteelement (auch Haltering genannt) auf, wobei der Außendurchmesser des hohlzylinderförmigen Grundkörpers und der Außendurchmesser des ringförmigen Halteelements gleich groß sind. In einer besonders bevorzugten Ausführungsvariante sind Grundkörper und Haltering einstückig (integriert) ausgebildet. Weiterhin ist es in einer bevorzugten Ausführungsvariante vorgesehen, dass die Ausnehmung im Bereich des Halterings angeordnet ist. In dieser Ausnehmung kann eine entsprechend dimensionierte Spülstromdrossel mittels eines Hakens dauerhaft, jedoch lösbar arretiert werden.Furthermore, it is preferred that the rinse water distributor has an elongated base body, wherein the base body is formed by an open hollow cylinder. Furthermore, the base body preferably has an annular retaining element (also called retaining ring), wherein the outer diameter of the hollow cylindrical base body and the outer diameter of the annular retaining element are the same size. In a particularly preferred embodiment, the base body and retaining ring are integrally formed (integrated). Furthermore, it is provided in a preferred embodiment that the recess is arranged in the region of the retaining ring. In this recess, a correspondingly dimensioned flushing flow throttle can be locked permanently but releasably by means of a hook.

In einer weiteren bevorzugten Ausführungsvariante ist es vorgesehen, dass das Halteelement eine Vielzahl von Ausnehmungen aufweist, die gleichmäßig über den Umfang des Halteelements (azimutal) verteilt sind. Die Mantelfläche des Grundkörpers erstreckt sich vorzugsweise über einen Winkel zwischen 120° und 240°, bevorzugt zwischen 160° und 200° und besonders bevorzugt über einen Winkel (azimutal) von 180°. Mit anderen Worten wird der Grundkörper in einer besonders bevorzugten Ausführungsvariante durch einen halben Hohlzylinder ausgebildet. Weiterhin ist es bevorzugt, dass der Spülwasserverteiler symmetrisch bezüglich seiner Längsachse ausgebildet ist. Die Symmetrieebene des Spülwasserverteilers verläuft vorzugsweise senkrecht zum Haltering, jedoch entlang des Normalenvektors einer durch den Haltering gebildeten Kreisfläche.In a further preferred embodiment, it is provided that the holding element has a plurality of recesses which are evenly distributed over the circumference of the holding element (azimuthally). The lateral surface of the main body preferably extends over an angle between 120 ° and 240 °, preferably between 160 ° and 200 ° and particularly preferably over an angle (azimuthal) of 180 °. In other words, the main body is formed in a particularly preferred embodiment by half a hollow cylinder. Furthermore, it is preferred that the rinse water distributor is formed symmetrically with respect to its longitudinal axis. The plane of symmetry of the rinse water distributor preferably runs perpendicular to the retaining ring, but along the normal vector of a circular surface formed by the retaining ring.

In einer weiteren bevorzugten Ausführungsvariante weist der Spülwasserverteiler im Inneren des (offenen) Hohlzylinders eine erste und eine zweite Innenwand auf, die sich nahezu über die gesamte Längserstreckung des Spülwasserverteilers und parallel zur Längsache desselben erstrecken. Vorzugsweise sind die erste und die zweite Innenwand im Bereich eines zweiten Endes abgewinkelt bzw. abgebogen, wobei sich die jeweiligen Abwinkelungen seitlich in jeweils gegenüberliegende Richtungen erstrecken. Vorzugsweise sind die erste Innenwand und die zweite Innenwand voneinander beabstandet, sodass sich zwischen erster Innenwand und zweiter Innenwand ein erster zentraler Spülwasserkanal innerhalb des Spülwasserverteilers ausbildet. Weiterhin bildet sich zwischen der Mantelfläche des Grundkörpers und der ersten Innenwand bzw. zwischen der Mantelfläche des Grundkörpers und der zweiten Innenwand jeweils ein zweiter und dritter Spülwasserkanal aus, wobei der zweite und dritte Spülwasserkanal jeweils seitliche Spülkanäle darstellen. Durch die abgewinkelten bzw. abgebogenen Bereiche erzeugen die seitlichen Spülwasserkanäle eine seitliche Flächenspülung im Toilettenbecken, wohingegen der zentrale Spülwasserkanal einen zentralen Bereich (bezogen auf den Ausfluss) spült.In a further preferred embodiment variant, the rinsing water distributor has a first and a second inner wall in the interior of the (open) hollow cylinder, which extend over almost the entire longitudinal extent of the rinsing water distributor and parallel to the longitudinal axis thereof. Preferably, the first and the second inner wall in the region of a second end are angled or bent, wherein the respective bends extend laterally in opposite directions. Preferably, the first inner wall and the second inner wall are spaced apart, so that between the first inner wall and the second inner wall, a first central Spülwasserkanal forms within the Spülwasserverteilers. Furthermore, it forms between the lateral surface of the Main body and the first inner wall or between the lateral surface of the base body and the second inner wall in each case a second and third Spülwasserkanal, wherein the second and third Spülwasserkanal each represent lateral Spülkanäle. Due to the angled or bent areas, the lateral flushing water channels generate a lateral surface flushing in the toilet bowl, whereas the central flushing water channel flushes a central area (based on the outflow).

Um eine besonders kompakte Integration des Spülwasserverteilers im (spülrandlosen) Toilettenbecken erreichen zu können, ist es vorgesehen, dass sich die abgebogenen bzw. abgewinkelten Bereiche der Innenwände nicht über den Umfang der Mantelfläche hinaus erstrecken. In einer weiteren bevorzugten Ausführungsvariante ist es vorgesehen, dass der Spülwasserverteiler zumindest teilweise aus einem nicht-keramischen Material, bevorzugt zumindest teilweise aus Kunststoff ausgebildet ist. Es ist besonders bevorzugt, dass der Spülwasserverteiler vollständig aus einem nicht-keramischen Material, bevorzugt vollständig aus Kunststoff ausgebildet ist. Weiterhin ist es bevorzugt, dass der Spülwasserverteiler einstückig ausgebildet wird. Insbesondere bei spülrandlosen WCs ist es herkömmlicherweise bekannt, keramische Spülwasserverteiler zu verwenden. Die entsprechenden Ausflussöffnungen der keramischen Spülwasserverteiler weisen material- und fertigungsbedingt hohe Toleranzen auf, wobei eine sehr geringe Uniformität bezüglich des Durchmessers der Ausflussöffnungen erreicht wird. Durch die Verwendung von Kunststoffen kann die Uniformität der Ausflusseigenschaften des Spülwasserverteilers vorteilhafterweise erhöht werden.In order to be able to achieve a particularly compact integration of the rinsing water distributor in the (rimless) toilet bowl, it is provided that the bent or angled regions of the inner walls do not extend beyond the circumference of the lateral surface. In a further preferred embodiment, it is provided that the rinse water distributor is at least partially made of a non-ceramic material, preferably at least partially made of plastic. It is particularly preferred that the rinse water manifold is made entirely of a non-ceramic material, preferably completely made of plastic. Furthermore, it is preferred that the rinse water distributor is formed in one piece. In particular, in the case of rimless WCs, it is conventionally known to use ceramic rinse water distributors. The corresponding outflow openings of the ceramic rinse water distributor have high material tolerances due to material and production, with very little uniformity with respect to the diameter of the outflow openings being achieved. The use of plastics can advantageously increase the uniformity of the outflow characteristics of the rinse water distributor.

Vorzugsweise ist der Kunststoff ein thermoplastischer Kunststoff. Besonders bevorzugt ist der Kunststoff Polystyrol.Preferably, the plastic is a thermoplastic. The plastic is particularly preferably polystyrene.

Alternativ ist es möglich, dass der Spülwasserverteiler zumindest teilweise (bevorzugt vollständig) aus anderen nicht-keramischen Materialien, beispielsweise aus Metall ausgebildet ist.Alternatively, it is possible for the rinse water distributor to be formed at least partially (preferably completely) from other non-ceramic materials, for example from metal.

Gemäß einem weiteren Aspekt der Erfindung wird ein spülrandloses Toilettenbecken offenbart, das einen Spülwasserverteiler aufweist, wobei der Spülwasserverteiler mindestens teilweise aus einem nicht-keramischen Material, bevorzugt zumindest teilweise Kunststoff ausgebildet ist. In einer besonders bevorzugten Variante ist der Spülwasserverteiler vollständig aus einem nicht-keramischen Material, bevorzugt vollständig Kunststoff ausgebildet. Vorzugsweise ist der Kunststoff ein thermoplastischer Kunststoff. Vorzugsweise ist der Kunststoff Polystyrol. Vorzugsweise ist der Spülwasserverteiler einstückig ausgebildet. Als spülrandloses Toilettenbecken wird im Sinne der vorliegenden Erfindung ein Toilettenbecken verstanden, dessen (obere) Auflagefläche (für einen Sitz) keine nach innen gerichtete Überragung (bzw. Überwölbung bzw. Überstand) aufweist bzw. eine solche Überragung lediglich in dem Bereich vorhanden ist, in dem sich der Spülwasserverteiler befindet. Das bedeutet, dass eine (obere) Auflagefläche (für einen Sitz) zumindest keine (vollständig) umlaufende nach innen gerichtete Überragung aufweist. Insbesondere ist es bevorzugt, dass eine ggf. (im Bereich eines Spülwasserverteilers) vorhandene nach innen gerichtete Überragung höchstens 50 %, bevorzugter höchstens in 20 % der Erstreckung des Umfangs der Innenschale vorhanden ist.According to a further aspect of the invention, a dishwashing toilet bowl is disclosed, which has a rinse water distributor, wherein the rinse water distributor is at least partially made of a non-ceramic material, preferably at least partially plastic. In a particularly preferred variant of the rinse water manifold is completely made of a non-ceramic material, preferably completely plastic. Preferably, the plastic is a thermoplastic. Preferably, the plastic is polystyrene. Preferably, the rinse water manifold is integrally formed. For the purposes of the present invention, a dishwashing toilet bowl is understood to mean a toilet bowl whose (upper) contact surface (for a seat) has no inwardly directed projection (or overhang or overhang) or such a projection is present only in the region the flushing water distributor is located. This means that an (upper) bearing surface (for a seat) has at least no (completely) circumferential inward-facing projection. In particular, it is preferred that an inwardly directed transfer (optionally in the region of a rinse water distributor) present at most 50%, more preferably at most 20%, of the extent of the circumference of the inner shell is present.

Gemäß einem weiteren Aspekt der Erfindung wird eine Spülstromdrossel für einen Spülwasserverteiler offenbart, wobei die Spülstromdrossel derart ausgebildet ist, dass sie in einen Spülwasserverteiler reversibel (lösbar), jedoch dauerhaft fixiert werden kann und somit ohne Beschädigung der Spülstromdrossel bzw. des Spülwasserverteilers zu einem späteren Zeitpunkt wieder aus dem Spülwasserverteiler herausgenommen werden kann. Dies hat insbesondere den Vorteil, dass bei einem Wechsel des Spülkastens nicht der gesamte Spülwasserverteiler, sondern lediglich die Spülstromdrossel getauscht werden muss. Die Spülstromdrossel weist daher Fixierungsmittel zur lösbaren Verriegelung bzw. reversiblen Fixierung in einem Spülwasserverteiler auf. Vorzugsweise weist die Spülstromdrossel einen ringförmigen Grundkörper mit einem Überstand aus, sodass der ringförmige Grundkörper in einen (offenen) hohlzylinderförmigen Spülwasserverteiler zu einem Anschlag (Überstand) eingeschoben werden kann.According to a further aspect of the invention, a flushing flow restrictor for a flushing water distributor is disclosed, wherein the flushing flow restrictor is designed such that it can be reversibly (detachably) but permanently fixed in a flushing water distributor and thus without damaging the flushing flow restrictor or the flushing water distributor at a later time can be taken out of the rinse water manifold again. This has the particular advantage that when changing the cistern not the entire Spülwasserverteiler, but only the Spülstromdrossel must be replaced. The flushing flow restrictor therefore has fixing means for releasably locking or reversible fixing in a flushing water distributor. The flushing flow throttle preferably has an annular base body with a projection, so that the annular base body can be pushed into an (open) hollow-cylindrical flushing water distributor to form a stop (projection).

Weiterhin ist es bevorzugt, dass die Spülstromdrossel im Bereich des ringförmigen Grundkörpers mindestens ein hakenförmiges Element aufweist, das in eine entsprechende Ausnehmung des Spülwasserverteilers eingreifen kann. Es ist besonders bevorzugt, dass die Ausnehmung des Spülwasserverteilers einen abgewinkelten Bereich aufweist, sodass die auf Anschlag in die Spülwasserverteiler eingeschobene Spülstromdrossel durch Drehung derselben dauerhaft, jedoch lösbar innerhalb des Spülwasserverteilers formschlüssig fixiert ist. Um diese dauerhafte, jedoch lösbare Fixierung einfach vornehmen zu können, ist es vorgesehen, dass die Spülstromdrossel vorzugsweise einen Griff aufweist.Furthermore, it is preferred that the flushing flow throttle has at least one hook-shaped element in the region of the annular base body, which can engage in a corresponding recess of the flushing water distributor. It is particularly preferred that the recess of the rinse water distributor has an angled region, so that the flushing flow restrictor inserted into the flushing water distributor in a fixed manner is fixed in a form-fitting manner by rotating the same permanently but releasably within the flushing water distributor. In order to make this permanent, but releasable fixation easy, it is provided that the purge flow throttle preferably has a handle.

Es sind innerhalb des ringförmigen Grundkörpers der Spülstromdrossel eine Vielzahl von Segmenten angeordnet, die einerseits eine Drosselung des Spülstroms hervorrufen und andererseits Verwirbelungen im Spülstrom eliminieren bzw. vermindern. In einer besonders bevorzugten Ausführungsvariante ist die Vielzahl von Segmenten umlaufend homogen (azimutal, uniform) angeordnet. Durch die entsprechenden Segmente (nachfolgend auch als Verwirbelungsminderungselemente bezeichnet) wird der Spülstrom homogenisiert und entsprechend vorhandene Verwirbelungen vermindert bzw. eliminiert. Es ist besonders bevorzugt, dass der Griff der Spülstromdrossel derart ausgebildet ist, dass er sich von (mindestens) einem Verwirbelungsverminderungselement über das ringförmige Grundelement in Flussrichtung hinaus erhebt, sich jedoch über das entsprechende Segment nicht in einer Richtung quer zur Flussrichtung des Spülwassers erstreckt, sodass durch den Griff keine Verwirbelungen verursacht werden. Vorzugsweise ist der Griff in einem zentralen Bereich der Spülstromdrossel angeordnet, da hierdurch eine besonders einfache Handhabung beim Einsetzen und Herausnehmen der Spülstromdrossel gewährleistet werden kann.There are a plurality of segments disposed within the annular body of the Spülstromdrossel, on the one hand cause a throttling of the purge stream and on the other hand eliminating or reducing turbulence in the purge stream. In a particularly preferred embodiment, the Variety of segments arranged circumferentially homogeneous (azimuthal, uniform). Through the corresponding segments (hereinafter also referred to as Verwirbelungsminderungselemente) of the purge stream is homogenized and correspondingly reduced or eliminated vortexes. It is particularly preferred that the handle of the Spülstromdrossel is formed so that it rises from (at least) a Verwirungsverminderungselement beyond the annular base in the flow direction, but does not extend over the corresponding segment in a direction transverse to the flow direction of the rinse water, so caused by the handle no turbulence. Preferably, the handle is arranged in a central region of the flushing flow restrictor, since in this way a particularly simple handling during insertion and removal of the flushing flow restrictor can be ensured.

Gemäß einem weiteren Aspekt der Erfindung wird ein Spülwasserverteiler für ein Toilettenbecken, insbesondere für ein spülrandloses Toilettenbecken offenbart, der bei Vermeidung von Spritzern eine besonders effiziente und gleichmäßige Ausspülung des Toilettenbeckens gewährleistet. Ein weiterer Vorteil des erfindungsgemäßen Spülwasserverteilers besteht darin, dass dieser besonders kompakt ausgebildet ist und somit effizient in ein spülrandloses Toilettenbecken eingesetzt werden kann, das über keinen bzw. einen sehr geringen Spülrandbereich verfügt, weshalb stark ausgedehnte Spülwasserverteiler optisch nachteilhaft wären. Der Spülwasserverteiler weist einen offenen hohlzylinderförmigen Grundkörper auf, wobei im inneren Bereich des Grundkörpers eine erste und eine zweite Innenwand angeordnet sind. Die beiden Innenwände verlaufen parallel zueinander und erstrecken sich in einer Höhe, die der Höhe des Mantels des Grundkörpers entspricht. Das bedeutet, dass die oberen Kanten der Innenwände vorzugsweise mit den Kanten der Mantelfläche des Grundkörpers in einer Ebene liegen. Der Spülwasserverteiler weist an einem seiner Enden jeweils abgewinkelte oder abgebogene Bereiche auf. Diese abgebogenen bzw. abgewinkelten Bereiche stellen Umlenkvorrichtungen für den Spülstrom dar. Durch die erste und zweite Innenwand werden innerhalb des Spülwasserverteilers drei Kanäle erzeugt, nämlich ein zentraler, erster Kanal zwischen erster und zweiter Innenwand, sowie zwei seitliche Kanäle zwischen erster Innenwand und Mantelfläche bzw. zweiter Innenwand und Mantelfläche. Die abgewinkelten bzw. abgebogenen Bereiche führen zu einer Umlenkung des Spülstroms der seitlichen Kanäle. Es ist vorgesehen, dass sich die abgebogenen bzw. abgewinkelten Bereiche nicht über die Ausdehnung der Mantelfläche hinaus erstrecken. Dadurch kann eine besonders effiziente und kompakte Bauweise des Spülwasserverteilers realisiert werden.According to a further aspect of the invention, a flushing water distributor for a toilet bowl, in particular for a bowl rimless toilet bowl is disclosed, which ensures a particularly efficient and uniform rinsing of the toilet bowl while avoiding splashing. Another advantage of the rinsing water distributor according to the invention is that it is particularly compact and thus can be used efficiently in a dishwashing toilet bowl, which has no or a very small Spülrandbereich, which would be visually disadvantageous stretched rinse water manifold. The rinse water distributor has an open hollow-cylindrical base body, wherein a first and a second inner wall are arranged in the inner region of the base body. The two inner walls are parallel to each other and extend at a height corresponding to the height of the shell of the body. This means that the upper edges of the inner walls are preferably in one plane with the edges of the lateral surface of the main body. The rinse water distributor has at each of its ends in each case angled or bent areas. These bent or angled areas represent deflection devices for the purge flow. Through the first and second inner wall, three channels are generated within the Spülwasserverteilers, namely a central, first channel between the first and second inner wall, and two lateral channels between the first inner wall and lateral surface or second inner wall and lateral surface. The angled or bent areas lead to a deflection of the purge flow of the lateral channels. It is envisaged that the bent or angled regions do not extend beyond the extent of the lateral surface. This allows a particularly efficient and compact design of Spülwasserverteilers be realized.

In einer weiteren bevorzugten Ausführungsvariante weist der Spülwasserverteiler auf der Außenseite der Mantelfläche im Bereich des Endes, an dem sich die abgebogenen Bereiche befinden, einen nach außen von der Mantelfläche abstehenden Haken (oder ein anderes Verbindungselement) auf, welches vorzugsweise die sichere Fixierung des Spülwasserverteilers innerhalb des Toilettenbeckens ermöglicht. Weiterhin ist es bevorzugt, dass der Spülwasserverteiler an einem den abgebogenen Bereichen gegenüberliegenden Ende des Grundkörpers einen Haltering aufweist, in den eine entsprechend ringförmig ausgebildete Spülstromdrossel lösbar fixiert werden kann. Insbesondere ist es bevorzugt, dass im Bereich des Halterings mindestens eine Ausnehmung vorgesehen ist, in die eine entsprechende Nut bzw. ein entsprechender Haken einer Spülstromdrossel eingerastet bzw. eingehakt werden kann. Besonders bevorzugt ist es, dass die Ausnehmung eine Abwinklung aufweist, sodass durch Verdrehen der Spülstromdrossel ein besonders sicherer Sitz der Spülstromdrossel im Spülwasserverteiler erreicht werden kann.In a further preferred embodiment, the rinsing water distributor on the outside of the lateral surface in the region of the end, where the bent portions are located on a protruding outwardly from the lateral surface hook (or other connection element), which preferably the secure fixation of the rinse water distributor within of the toilet bowl. Furthermore, it is preferred that the rinsing water distributor has a retaining ring at an end of the base body opposite the bent regions, into which a corresponding annularly designed flushing flow throttle can be detachably fixed. In particular, it is preferred that at least one recess is provided in the region of the retaining ring, into which a corresponding groove or a corresponding hook of a flushing flow throttle can be snapped or hooked. It is particularly preferred that the recess has an angled portion, so that a particularly secure fit of the flushing flow restrictor in the flushing water distributor can be achieved by turning the flushing flow restrictor.

Ausführliche Beschreibung der ZeichnungenDetailed description of the drawings

Die Figuren 1 und 2 zeigen jeweils eine schematisch geschnittene Darstellung eines Ausschnittes eines Toilettenbeckens 10 mit Spülwasserverteiler 14 und Spülstromdrossel 18. Während die Schnittebene in Figur 1 vertikal verläuft, verläuft die Schnittebene der Figur 2 horizontal. Das Toilettenbecken 10 weist eine Innenschale 30 und eine Außenschale 42 auf. Spülwasser wird über den Spülwasserzulauf 12 in den Spülwasserverteiler 14 geleitet und dort in drei unterschiedliche Kanäle unterteilt. Diese Kanäle werden durch die Mantelfläche des Grundkörpers 20 die erste Innenwand 26 und die zweite Innenwand 28 gebildet. Wie insbesondere aus Figur 2 ersichtlich, weisen die Innenwände 26, 28 in dem der Innenschale 30 zugewandten Bereich abgebogene Bereiche 44 und 46 auf, die zur Umlenkung des Spülwassers in seitliche Ausflussöffnungen 36 führen. Das im mittleren Kanal zwischen den Innenwänden 26, 28 geführte Spülwasser wird durch eine weitere Ausflussöffnung 36 (untere Ausflussöffnung), die insbesondere in Figur 1 ersichtlich ist, in einen unteren, zentralen Bereich der Innenschale 30 geleitet. Um den aus einem Kunststoff (Polystyrol) ausgebildeten Spülwasserverteiler 14 für einen Benutzer des Toilettenbeckens optisch nicht sichtbar werden zu lassen, weist das spülrandlose Toilettenbecken 10 eine Verblendung 60 auf. Das Toilettenbecken 10 ist ein spülrandloses Toilettenbecken, da die Verblendung 60, die die Auflagefläche 32 nach innen überragt, lediglich in dem Bereich angeordnet ist, in dem sich der Spülwasserverteiler 14 befindet. Mit anderen Worten ist die einen Spülrand ausbildende Verblendung 60 lediglich in einem sehr kleinen Bereich bezogen auf den Umfang der Innenschale 30 vorhanden. Insbesondere ist es bevorzugt, dass diese Verblendung 60 bzw. ein sonstiger Spülrand lediglich in höchstens 50 %, bevorzugter lediglich in höchstens 20 % der Erstreckung des Umfangs der Innenschale 30 im Bereich der Auflagefläche 32 vorhanden ist.The FIGS. 1 and 2 each show a schematic sectional view of a section of a toilet bowl 10 with Spülwasserverteiler 14 and Spülstromdrossel 18. While the cutting plane in FIG. 1 runs vertically, the cutting plane runs the FIG. 2 horizontal. The toilet bowl 10 has an inner shell 30 and an outer shell 42. Rinse water is passed through the Spülwasserzulauf 12 in the rinse water manifold 14 and divided there into three different channels. These channels are formed by the lateral surface of the base body 20, the first inner wall 26 and the second inner wall 28. As in particular from FIG. 2 can be seen, the inner walls 26, 28 in the inner shell 30 facing region bent portions 44 and 46, which lead to the deflection of the rinse water in lateral outflow openings 36. The rinsing water guided in the middle channel between the inner walls 26, 28 is conveyed through a further outflow opening 36 (lower outflow opening), which in particular flows in FIG. 1 can be seen, passed into a lower, central region of the inner shell 30. In order to make the made of a plastic (polystyrene) Spülwasserverteiler 14 optically invisible to a user of the toilet bowl, the rimless toilet bowl 10 has a veneer 60. The toilet bowl 10 is a bowl rimless toilet bowl, since the veneer 60, which projects beyond the support surface 32 inwardly, is arranged only in the region in which the rinse water distributor 14 is located. In other words, the veneering 60 forming a flushing rim is present only in a very small area relative to the circumference of the inner shell 30. In particular, it is preferred that this veneer 60 or another rinsing edge is present only in at most 50%, more preferably only in at most 20% of the extent of the circumference of the inner shell 30 in the region of the support surface 32.

Aufgrund der Geometrie des Spülwasserverteilers 14 wird das über den Spülwasserzufluss 12 eingespeiste Spülwasser in drei Kanäle unterteilt und über entsprechende drei Öffnungen 36 in die Innenschale 30 des Toilettenbeckens eingespült. Wie aus Figur 1 ersichtlich ist, weist das Toilettenbecken 10 eine Aufnahme 34 für den Spülwasserverteiler 14 auf. Diese Aufnahme 34 ist ein in den Dimensionen des Spülwasserverteilers 14 ausgebildeter Hohlraum in den der Spülwasserverteiler 14 eingeschoben wird. In einer bevorzugten Ausführungsvariante weist diese Aufnahme 34 eine zusätzliche Ausnehmung 38 auf, die dazu führt, dass diejenige Fläche, an der der Spülwasserverteiler 14 in der Aufnahme 34 (im oberen Bereich) anliegt, eine abgewinkelte Form aufweist. Erfindungsgemäß ist es vorgesehen, dass der Spülwasserverteiler einen Haken 40 aufweist, der beim Einschieben des Spülwasserverteilers 14 in die Aufnahme 34 in den abgewinkelten Bereich der Ausnehmung 38 einrastet, sodass der Spülwasserverteiler 14 sicher und fest, jedoch lösbar in der Aufnahme 34 fixiert werden kann. Weiterhin ist es erfindungsgemäß vorgesehen, dass der Spülwasserverteiler 14 ein Halteelement 22 aufweist, welches ringförmig ausgebildet ist. Es ist besonders bevorzugt, dass das Halteelement 22 des Spülwasserverteilers 14 mit den Dimensionen einer ebenfalls ringförmig ausgebildeten Spülstromdrossel 18 derart korrespondiert, dass die Spülstromdrossel 18 in das Halteelement 22 des Spülwasserverteilers eingeschoben werden kann. Erfindungsgemäß weisen der Spülwasserverteiler 14 und/oder die Spülstromdrossel 18 die Fixierungsmittel zur lösbaren Verriegelung der Spülstromdrossel 18 im Spülwasserverteiler 14 auf. In einer besonders bevorzugten Ausführungsvariante weist der Spülwasserverteiler 14 im Bereich des Halteelements 22 mindestens eine Ausnehmung 24 auf (siehe Figur 5d), in die eine entsprechende Nut bzw. ein entsprechender Haken 52 (siehe Figur 6d) der Spülstromdrossel 18 so eingehakt werden kann, dass die Spülstromdrossel 18 sicher, jedoch lösbar im Spülwasserverteiler 14 eingehakt werden kann. Daher ist es ebenfalls möglich, die Spülstromdrossel 18 im Falle eines Wechsels des Spülkastens wieder auszuhaken und eine entsprechend an den Spülstrom des neuen Spülkastens angepasste Spülstromdrossel (ebenfalls lösbar) in den Spülwasserverteiler 14 einzusetzen.Due to the geometry of the rinse water distributor 14, the rinse water fed in via the rinse water inflow 12 is subdivided into three channels and flushed into the inner shell 30 of the toilet bowl via corresponding three openings 36. How out FIG. 1 it can be seen, the toilet bowl 10 has a receptacle 34 for the rinse water manifold 14. This receptacle 34 is formed in the dimensions of the rinse water manifold 14 cavity into which the rinse water manifold 14 is inserted. In a preferred embodiment, this receptacle 34 has an additional recess 38, which results in that the surface on which the flushing water distributor 14 rests in the receptacle 34 (in the upper region) has an angled shape. According to the invention, it is provided that the rinse water distributor has a hook 40 which engages in the receptacle 34 in the angled portion of the recess 38 upon insertion of the rinse water manifold 14, so that the rinse water distributor 14 safe and strong, but solvable can be fixed in the receptacle 34. Furthermore, it is inventively provided that the rinse water distributor 14 has a holding element 22 which is annular. It is particularly preferred that the holding element 22 of the flushing water distributor 14 with the dimensions of a likewise annular design Spülstromdrossel 18 corresponds such that the Spülstromdrossel 18 can be inserted into the holding element 22 of the flushing water distributor. According to the invention, the flushing water distributor 14 and / or the flushing flow restrictor 18 have the fixing means for the releasable locking of the flushing flow restrictor 18 in the flushing water distributor 14. In a particularly preferred embodiment, the rinsing water distributor 14 has at least one recess 24 in the region of the holding element 22 (see FIG FIG. 5d ), in which a corresponding groove or a corresponding hook 52 (see FIG. 6d ) of the purge flow restrictor 18 can be hooked so that the purge flow restrictor 18 can be safely but releasably hooked into the rinse water manifold 14. Therefore, it is also possible to unhook the Spülstromdrossel 18 in the case of a change of the cistern again and a correspondingly adapted to the purge flow of the new cistern flushing flow restrictor (also releasably) in the flushing water manifold 14 to use.

Die Figuren 3 und 4 zeigen detaillierte perspektivische Ansichten des erfindungsgemäßen Spülwasserverteilers 14 sowie der Spülstromdrossel 18. Wie bereits erläutert, weist der Spülwasserverteiler 14 vorzugsweise einen im Wesentlichen hohlzylinderförmig ausgebildeten Grundkörper 20 auf. Der Querschnitt dieses Grundkörpers bildet einen Teilkreis aus, wobei der Spülwasserverteiler 14 ein ringförmiges Halteelement 22 aufweist, mit anderen Worten ist der Hohlzylinder im Bereich des Halteelements 22 geschlossen wobei er im sonstigen Bereich offen ist und einen azimutalen Winkel von vorzugsweise 180° und im Bereich des dem Halteelement 22 gegenüberliegenden Endes von weniger als 180° aufweist. Zur Erzeugung von vorzugsweise drei Spülwasserkanälen weist der Spülwasserverteiler 14 mindestens eine erste Innenwand 26 und eine zweite Innenwand 28 auf, die parallel zueinander verlaufen, sodass ein erster zentraler Kanal zwischen den Innenwänden 26 und 28 und seitliche Kanäle zwischen der Innenwand 26 und der Mantelfläche des Grundkörpers 20 bzw. der Innenwand 28 und der Mantelfläche des Grundkörpers 20 ausgebildet werden. Das durch das ringförmige Halteelement 22 einströmende Spülwasser wird dann, wie durch die Pfeile angedeutet, in die drei Kanäle unterteilt und in unterschiedliche Richtungen in das Toilettenbecken eingespült. Dazu weisen die Innenwände 26, 28 im Bereich ihrer Enden abgebogene Flächen 44, 46 auf. Zur kompakten Ausbildung des Spülwasserverteilers 14 ragen die abgebogenen Enden 44, 46 jedoch seitlich nicht über eine Projektion der Mantelfläche des Grundkörpers 20 entlang der Längsachse des Spülwasserverteilers 14 heraus. In einer besonders bevorzugten Ausführungsvariante schließen die abgebogenen Enden 44, 46 gerade mit der Projektion der Mantelfläche des Grundkörpers 20 ab. Um einen effizienten Ausfluss der seitlichen Kanäle zu gewährleisten, ist es vorgesehen, dass sich der hohlzylinderförmige Grundkörper 20 im Bereich der abgebogenen Enden 44, 46 über einen geringeren (azimutalen) Winkelbereich erstreckt als in einem (auf die Längsachse des Spülwasserverteilers 14 bezogenen) zentralen Bereich des Grundkörpers 20. Wie aus Figur 4 ersichtlich, weist der Spülwasserverteiler 14 auf der Rückseite einen nach außen ragenden Haken 40 auf, der eine sichere Fixierung des Spülwasserverteilers 14 in der Aufnahme 34 des Toilettenbeckens 10 gewährleistet. Es ist besonders bevorzugt, dass die Mantelfläche im Bereich des Hakens 40 eine weitere Ausnehmung aufweist, die zum Ausbau des Spülwasserverteilers 14 dienen kann.The Figures 3 and 4 show detailed perspective views of the rinse water distributor 14 and the Spülstromdrossel invention 18. As already explained, the rinse water distributor 14 preferably has a substantially hollow cylindrical body 20 formed. The cross section of this body forms a partial circle, wherein the rinse water distributor 14 has an annular retaining element 22, in other words, the hollow cylinder in the region of the holding member 22 is closed while it is open in the other area and an azimuthal angle of preferably 180 ° and in the region of Having the holding element 22 opposite end of less than 180 °. To generate preferably three rinse water channels, the rinse water distributor 14 has at least one first inner wall 26 and one second inner wall 28 which run parallel to each other, so that a first central channel between the inner walls 26 and 28 and lateral channels between the inner wall 26 and the outer surface of the base body 20 and the inner wall 28 and the lateral surface of the base body 20 are formed. The rinsing water flowing in through the annular retaining element 22 is then subdivided into the three channels, as indicated by the arrows, and flushed into the toilet bowl in different directions. For this purpose, the inner walls 26, 28 in the region of their ends bent surfaces 44, 46. For the compact design of the rinsing water distributor 14, however, the bent ends 44, 46 do not protrude laterally beyond a projection of the lateral surface of the main body 20 along the longitudinal axis of the rinsing water distributor 14. In a particularly preferred Embodiment close the bent ends 44, 46 straight with the projection of the lateral surface of the base body 20 from. In order to ensure an efficient outflow of the lateral channels, it is provided that the hollow cylindrical basic body 20 extends in the region of the bent ends 44, 46 over a smaller (azimuthal) angular range than in a central region (related to the longitudinal axis of the rinsing water distributor 14) of the main body 20. How out FIG. 4 can be seen, the Spülwasserverteiler 14 on the back of an outwardly projecting hook 40, which ensures a secure fixation of the rinse water distributor 14 in the receptacle 34 of the toilet bowl 10. It is particularly preferred that the lateral surface in the region of the hook 40 has a further recess, which can serve to dismantle the rinsing water distributor 14.

Wie aus den Figuren 3 und 4 ersichtlich, wird die Spülstromdrossel 18 in das Halteelement 22 des Spülwasserverteilers 14 eingesetzt. Die Spülstromdrossel 18 weist einen ringförmigen Grundkörper 50 auf, wobei der Außendurchmesser des ringförmigen Grundkörpers 50 dem Innendurchmesser des ringförmigen Halteelements 22 entspricht oder etwas kleiner als dieser ausgebildet ist, sodass die Spülstromdrossel 18, insbesondere der ringförmige Grundkörper 50 formschlüssig in das ringförmige Halteelement 22 des Spülwasserverteilers 14 eingeschoben werden kann. Weiterhin weist der Grundkörper 50 einen über dessen Radius ragenden Überstand 54 auf, sodass die Spülstromdrossel 18 mit dem Grundkörper 50 bis auf Anschlag (bis zum Überstand 54) in das ringförmige Halteelement 22 des Spülwasserverteilers 14 eingeschoben werden kann. In einer besonders bevorzugten Ausführungsvariante stimmt der Außendurchmesser des Überstands 54 mit dem Außendurchmesser des ringförmigen Halteelements 22 überein. Dadurch können potenziell entstehende Verwirbelungen im Spülstrom eliminiert bzw. reduziert werden. Um (weitere) Verwirbelungen effizient reduzieren zu können, ist es erfindungsgemäß vorgesehen, dass die Spülstromdrossel 18 in ihrem Querschnitt (bzgl. der Flussrichtung) eine Vielzahl von Segmenten 58 aufweist, die zu einer Harmonisierung bzw. Entwirbelung des Spülstroms führen. Es ist besonders bevorzugt, dass sämtliche Elemente 58 den gleichen Querschnitt bzgl. der Spülstromrichtung aufweisen und umlaufend uniform angeordnet sind, also die durch die einzelnen Segmente 58 eingeschlossenen Winkel im zentralen Bereich der Spülstromdrossel 18 gleich groß sind. Vorzugsweise beträgt die Anzahl der Segmente zwischen 2 und 20, besonders bevorzugt zwischen 5 und 10. Dies führt zu einer besonders effizienten Entwirbelung des Spülstroms.Like from the Figures 3 and 4 can be seen, the Spülstromdrossel 18 is inserted into the holding element 22 of the rinse water distributor 14. The Spülstromdrossel 18 has an annular base body 50, wherein the outer diameter of the annular base body 50 corresponds to the inner diameter of the annular support member 22 or slightly smaller than this is formed, so that the Spülstromdrossel 18, in particular the annular body 50 form-fitting manner in the annular support member 22 of Spülwasserverteilers 14 can be inserted. Furthermore, the main body 50 has a projecting beyond its radius projection 54, so that the purge flow restrictor 18 can be inserted with the main body 50 to stop (up to the supernatant 54) in the annular support member 22 of the rinse water manifold 14. In a particularly preferred embodiment variant, the outer diameter of the projection 54 coincides with the outer diameter of the annular retaining element 22. This can eliminate or reduce potential turbulence in the purge stream. In order to be able to reduce (further) turbulence efficiently, it is provided according to the invention that the purge flow throttle 18 has in its cross section (with respect to the flow direction) a plurality of segments 58 which lead to a harmonization or Entwirbelung the purge flow. It is particularly preferred that all elements 58 have the same cross-section with respect to the flushing flow direction and are uniformly arranged circumferentially, ie the angles enclosed by the individual segments 58 in the central region of the flushing flow restrictor 18 are the same. Preferably, the number of segments is between 2 and 20, more preferably between 5 and 10. This leads to a particularly efficient Entwirbelung the purge stream.

Die Figuren 5a bis 5d zeigen den erfindungsgemäßen Spülwasserverteiler aus den sechs Hauptperspektiven (seitliche Ansicht Figur 5a, Sicht von unten sowie von vorn und hinten Figur 5b, seitliche Ansicht der gegenüberliegenden Seite Figur 5c und Aufsicht von oben Figur 5d). Wie insbesondere aus den Figuren 5b und 5d erkennbar ist, weist der Spülwasserverteiler 14 im oberen Bereich, insbesondere im Bereich zwischen Haltelement 22 und Grundkörper 20 eine Ausnehmung 24 auf. Da der Grundkörper 20 und der Haltering 22 einstückig ausgebildet sind, ist die Ausnehmung 24 sowohl im Halteelement 22 als auch im Grundkörper 20 integriert. Die Ausnehmung 24 ist derart ausgebildet, dass sie im äußeren Bereich (also im Bereich des dem Spülwasserzulauf 12 zugewandten Endes) einen ersten Ausnehmungsbereich aufweist, der sich entlang der Längsachse des Spülwasserverteilers 14 erstreckt und einen zweiten, sich an den ersten anschließenden Bereich aufweist, der sich quer zur Längsrichtung des Spülwasserverteilers 14 (d. h. quer zur Spülwasserrichtung) erstreckt. Durch diese abgewinkelte Ausbildung der Ausnehmung 24 ist es möglich, ein entsprechendes Element der Spülstromdrossel 18 (z. B. Haken 52) zunächst ein Stück weit in die Ausnehmung 24 einzuschieben und dann durch Drehung der Spülstromdrossel 18 dieselbe fest im Spülwasserverteiler 14 zu arretieren. Somit bilden die Ausnehmung 24 sowie der korrespondierende Haken 52 der Spülstromdrossel 18 die entsprechenden Fixierungsmittel zur lösbaren Verriegelung der Spülstromdrossel 18 im Spülwasserverteiler 14 aus.The FIGS. 5a to 5d show the Spülwasserverteiler invention from the six main perspectives (side view FIG. 5a , View from below as well as from the front and back FIG. 5b , lateral view of the opposite side FIG. 5c and top view FIG. 5d ). As in particular from the FIGS. 5b and 5d can be seen, the rinse water distributor 14 has a recess 24 in the upper region, in particular in the region between the holding element 22 and the base body 20. Since the base body 20 and the retaining ring 22 are integrally formed, the recess 24 is integrated both in the retaining element 22 and in the base body 20. The recess 24 is designed such that in the outer region (ie in the region of the end facing the flushing water inlet 12) it has a first recess region which extends along the longitudinal axis of the flushing water distributor 14 and has a second region adjacent to the first flushing region extending transversely to the longitudinal direction of the rinse water manifold 14 (ie, transverse to the rinse water direction). As a result of this angled design of the recess 24, it is initially possible to insert a corresponding element of the flushing flow throttle 18 (eg hook 52) into the recess 24 a little way and then lock it in the flushing water distributor 14 by rotation of the flushing flow restrictor 18. Thus, the recess 24 and the corresponding hook 52 of the Spülstromdrossel 18 form the corresponding fixing means for releasably locking the Spülstromdrossel 18 in the flushing water manifold 14.

Eine entsprechende zum Spülwasserverteiler 14 der Figur 5 korrespondierende und mit diesem zusammenwirkende Spülstromdrossel 18 ist in Figur 6 in verschiedenen Perspektiven dargestellt (Figur 6a Aufsicht, Figur 6b seitliche, schematische Ansicht, Figur 6c seitliche schematische Ansicht um 90° gedreht und Figur 6d perspektivische Ansicht). Wie aus den Figuren 6a bis 6d ersichtlich wird, weist die Spülstromdrossel 18 mindestens einen, vorzugsweise drei Haken 52 auf, deren Abmessungen mit der Ausnehmung 24 (Figur 5d) des Spülwasserverteilers 14 derart korrespondieren, dass die Spülstromdrossel 18 bis zu ihrem Überstand 54 in das ringförmige Halteelement 22 des Spülwasserverteilers 14 eingeschoben werden kann und dann fest anliegt. Mindestens einer der Haken 52 der Spülstromdrossel 18 greift dabei in die Ausnehmung 24 des Spülwasserverteilers 14 ein. Nun kann die Spülstromdrossel 18 in einfacher Weise am Griff 56 im Uhrzeigersinn gedreht werden, wobei dieselbe dadurch fest, jedoch lösbar im Spülwasserverteiler 14 fixiert wird. In einer besonders bevorzugten Ausführungsvariante weist der Spülwasserverteiler 14 lediglich eine Ausnehmung 24, die Spülstromdrossel 18 jedoch drei im Winkel von jeweils 120° zueinander angeordnete Haken 52 auf. Die Haken 52 haben eine radiale Ausdehnung entsprechend dem Überstand 54 bzw. dem Haltelement 22. Obwohl nur eine Ausnehmung 24 vorgesehen ist, kann die Spülstromdrossel 18 leicht verkippt und dadurch mit ihren drei Haken 52 in das ringförmige Halteelement 22 (bis zum Überhang 54) eingeschoben werden. Nach einer Verdrehung fixiert der in der Ausnehmung 24 befindliche Haken 52 die Spülstromdrossel 18 formschlüssig, wobei sich die beiden anderen Haken 52 hinter dem ringförmigen Halteelement verhaken und somit einen sicheren Sitz der Spülstromdrossel 18 ermöglichen und insbesondere ein Verkippen derselben verhindern. Dies ermöglicht eine besonders einfache Verriegelung, da zum Einbringen der Spülstromdrossel 18 lediglich das räumliche Übereinstimmen eines Hakens 52 mit der Ausnehmung 24 erreicht werden muss, wobei die beiden anderen Haken 52 hinter das Haltelement 22 (bei leicht schräger Einführung der Spülstromdrossel 18) eingreifen.A corresponding to the rinse water distributor 14 of FIG. 5 Corresponding and cooperating with this Spülstromdrossel 18 is in FIG. 6 presented in different perspectives ( FIG. 6a At sight, FIG. 6b lateral, schematic view, FIG. 6c lateral schematic view rotated by 90 ° and FIG. 6d perspective view). Like from the FIGS. 6a to 6d it can be seen, the flushing flow throttle 18 has at least one, preferably three hooks 52, the dimensions of which with the recess 24 (FIG. FIG. 5d ) of the rinsing water distributor 14 correspond to one another such that the rinsing flow throttle 18 can be pushed into its upper projection 54 into the annular holding element 22 of the rinsing water distributor 14 and then bears tightly. At least one of the hooks 52 of the flushing flow throttle 18 engages in the recess 24 of the flushing water distributor 14. Now the Spülstromdrossel 18 can be rotated in a simple manner on the handle 56 in a clockwise direction, wherein the same is thereby firmly, but releasably fixed in the flushing water manifold 14. In a particularly preferred embodiment, the flushing water distributor 14 has only one recess 24, but the flushing flow throttle 18 has three hooks 52 arranged at an angle of 120 ° to one another. Although only one recess 24 is provided, the purge flow restrictor 18 is easily tilted and thereby inserted with its three hooks 52 into the annular retainer 22 (up to the overhang 54) become. After rotation, the hook 52 located in the recess 24 fixes the Spülstromdrossel 18 positively, wherein the two other hooks 52 catch behind the annular support member and thus allow a secure fit of Spülstromdrossel 18 and in particular prevent tilting of the same. This allows a particularly simple locking, since for the introduction of Spülstromdrossel 18 only the spatial matching of a hook 52 with the recess 24 must be achieved, the other two hooks 52 engage behind the support member 22 (with slightly oblique introduction of Spülstromdrossel 18).
