Aus dem Stand der Technik sind Klosettspülvorrichtungen bekannt geworden. Beispielsweise offenbart die
Die in der
Durch die zunehmende Verbreitung von spülrandlosen Sanitärartikeln, wie Klosettschüsseln oder Urinalen, ist die Problematik eines unkontrollierten Überschiessens des Spülwasser in den Fokus der Benutzer gekommen. In diesem Zusammenhang ist auch das Drosseln des Spülstroms sehr wichtig geworden.Due to the increasing use of rimless sanitary articles, such as lavatory bowls or urinals, the problem of an uncontrolled overshoot of the rinse water has come into the focus of the user. In this context, the throttling of the purge flow has become very important.
Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine Spülvorrichtung anzugeben, welche die Nachteile des Standes der Technik überwindet. Insbesondere ist es eine Aufgabe der vorliegenden Erfindung, eine Spülvorrichtung anzugeben, welche eine verbesserte Drosselung des Spülstroms erlaubt, so dass die Strömung kontrollierter einem Sanitärartikel zugeleitet werden kann.Starting from this prior art, it is an object of the present invention to provide a flushing device which overcomes the disadvantages of the prior art. In particular, it is an object of the present invention to provide a flushing device which allows an improved throttling of the flushing flow so that the flow can be directed to a sanitary article in a controlled manner.
Diese Aufgabe wird durch den Gegenstand vom Anspruch 1 gelöst. Demgemäss umfasst eine Spülvorrichtung einen Spülkasten, ein vom Spülkasten abgehendes Spülrohr mit einem sich dem Spülkasten anschliessenden und entlang einer ersten Mittelachse verlaufendem ersten Rohrabschnitt, einem sich dem ersten Rohrabschnitt anschliessenden Rohrbogen sowie einem sich dem Rohrbogen anschliessenden und entlang einer zweiten Mittelachse verlaufenden zweiten Rohrabschnitt mit einem Rohraustritt, und ein im Spülrohr angeordnetes Drosselelement zur Drosselung des Spülstroms im Spülrohr. Der zweite Rohrabschnitt ist derart ausgebildet, dass dieser in ein Verbindungsrohr mündet, welches zu einem Sanitärartikel geführt wird, wobei über das Verbindungsrohr das Spülwasser dem Sanitärartikel zugeführt wird. Das Drosselelement ist in einem kurzen Abstand zum geometrischen Rohrbogenende des Rohrbogens angeordnet. In einer besonders bevorzugten Ausführungsform ist das Drosselelement direkt, das heisst unmittelbar, beim geometrischen Rohrbogenende im zweiten Rohrabschnitt angeordnet.This object is solved by the subject matter of
Durch die Anordnung des Drosselelementes im besagten Abstand bzw. direkt nach dem Rohrbogen ergeht der Vorteil, dass das durch das Spülrohr hindurchfliessende Spülwasser, welches im vertikalen Rohrteil durch die Gravitation beschleunigt wird, zuerst durch die Drossel nach dem Rohrbogen abgebremst wird; und anschliessend nach dem Rohrbogen ein typischerweise geradlinig im Wesentlichen in der Horizontalen verlaufendes Verbindungsrohr in den Sanitärartikel folgt, was die Strömung des Spülwassers vor dem Einschiessen in den Sanitärartikel wieder beruhigt. Hierdurch kann die Strömung kontrollierter in den Sanitärartikel geführt werden, was für die Verteilung des Spülwassers im Sanitärartikel von Vorteil ist, weil beispielsweise Spritzer und/oder ein Überschiessen aus dem Sanitärartikel vermieden werden können.The arrangement of the throttle element at said distance or directly after the pipe bend has the advantage that the flushing water flowing through the flushing pipe, which is accelerated in the vertical pipe part by gravity, is first braked by the throttle after the pipe bend; and then followed by the pipe bend a typically straight substantially horizontally extending connecting pipe in the sanitary article, which calms the flow of rinse water before shooting into the sanitary article again. In this way, the flow can be performed in a controlled manner in the sanitary article, which is advantageous for the distribution of the rinse water in the sanitary article, for example, because splashes and / or overshoot can be avoided from the sanitary article.
Mit anderen Worten gesagt ist das Drosselelement an der tiefsten Stelle im Spülkastenströmungssystem und möglichst weit von der Mündung in den Sanitärartikel entfernt angeordnet. Nach dem Drosselement kann sich das Spülwasser also nicht weiter beschleunigen und die durch das Drosselelement verursachte Geschwindigkeitserhöhung kann sich bis zum Eintritt in den Sanitärartikel aufgrund der weit entfernten Anordnung wieder normalisieren.In other words, the throttle element is located at the lowest point in the Spülkastenströmungssystem and as far away from the mouth in the sanitary article. After the throttle element, the rinse water can therefore not accelerate further and caused by the throttle element speed increase can normalize until it enters the sanitary article due to the distant arrangement again.

Durch die drehfeste Lagerung wird erreicht, dass das Drosselelement lagerichtig eingesetzt wird, was je nach Ausbildung des Drosselelementes für dessen Drosselwirkung wichtig sein kann.Preferably, the second pipe section has a bearing for the throttle element, wherein the throttle element is insertable into the bearing and wherein the throttle element is preferably rotatably mounted in the bearing. Due to the non-rotatable mounting is achieved that the throttle element is used in the correct position, which may be important depending on the design of the throttle element for the throttle effect.
Die Lagerstelle liegt vorzugsweise vor der Aufnahme zwischen der Aufnahme und dem Rohrbogen.The bearing is preferably before recording between the recording and the pipe bend.
Vorzugsweise weist die Lagerstelle einen Anschlag auf, an welchem das Drosselelement ansteht. Weiter ist durch das in die Aufnahme einzusetzende Verbindungsrohr ein Anschlag für das Drosselelement bereitstellbar, derart, dass das Drosselelement zwischen dem Anschlag der Aufnahme und dem Verbindungsrohr geklemmt ist. Das Verbindungsrohr kann beim Einbau abgelängt werden.Preferably, the bearing has a stop on which the throttle element is present. Furthermore, a stop for the throttle element can be provided by the connecting tube to be inserted into the receptacle, such that the throttle element is clamped between the stop of the receptacle and the connecting tube. The connecting pipe can be cut to length during installation.
Anstelle des oben beschriebenen einsetzbaren Drosselelements kann das Drosselelement in einer alternativen Variante auch integral am Rohrbogen bzw. dem zweiten Rohrabschnitt angeformt sein.Instead of the above-described usable throttle element, the throttle element may be integrally formed on the pipe bend or the second pipe section in an alternative variant.
Bezüglich der Radien der Rohrbogen ist eine bevorzugte Variante dadurch charakterisiert, dass der Aussenradius des Rohrbogens im Wesentlichen konstant ist und/oder dass der Innenradius des Rohrbogens im Wesentlichen konstant ist.With respect to the radii of the pipe bend, a preferred variant is characterized in that the outer radius of the pipe bend is substantially constant and / or that the Inner radius of the pipe bend is substantially constant.
Eine weitere bevorzugte Variante ist dadurch charakterisiert, dass der Aussenradius des Rohrbogens sich vom geometrischen Rohrbogenbeginn über die Krümmung des Rohrbogens verändert, derart, dass der Aussenradius des Rohrbogens zum geometrischen Rohrbogenende hin kleiner oder grösser wird, und dass der Innenradius des Rohrbogens vorzugsweise im Wesentlichen konstant ist. Hierdurch kann die Strömung im Bereich des Rohrbogens weiter optimiert werden. Die Ausbildung des Aussenradius kann dabei ein optimales Einleiten der Strömung zum Drosselelement ermöglichen.A further preferred variant is characterized in that the outer radius of the pipe bend changes from the geometrical beginning of the pipe bend over the curvature of the pipe bend such that the outer radius of the pipe bend becomes smaller or larger towards the geometric pipe bend end, and that the inner radius of the pipe bend is preferably substantially constant is. As a result, the flow in the region of the pipe bend can be further optimized. The formation of the outer radius can thereby allow an optimal introduction of the flow to the throttle element.
Der Innenradius wie auch der Aussenradius können in anderen Ausführungsformen auch anders ausgebildet sein. Insbesondere kann der Aussenradius auch konstant sein.The inner radius as well as the outer radius may be formed differently in other embodiments. In particular, the outer radius can also be constant.
Vorzugsweise stellt das Drosselelement eine Querschnittsverengung des zweiten Rohrabschnitts bereit, wobei die Querschnittsverengung den Querschnitt des zweiten Rohrabschnittes um 5% bis 30% oder um 10% bis 25% verkleinert.Preferably, the throttle element provides a cross-sectional constriction of the second pipe section, wherein the cross-sectional constriction reduces the cross section of the second pipe section by 5% to 30% or by 10% to 25%.
In einer besonders bevorzugten Ausführungsform weist das Drosselelement mehrere Drosselstege auf, welche sich radial von der zweiten Mittelachse des zweiten Rohrabschnittes nach aussen erstrecken. Hierdurch werden mehrere kuchenstückartige Segmente gebildet, durch welche das Wasser hindurchtreten kann. Durch diese Art von Drosselelement ergeht der Vorteil, dass die Strömung in mehrere Segmente aufgeteilt wird und so gleichmässig gedrosselt wird.In a particularly preferred embodiment, the throttle element has a plurality of throttle webs, which extend radially outward from the second center axis of the second pipe section. As a result, several cake-piece-like segments are formed, through which the water can pass. This type of throttle element has the advantage that the flow is divided into several segments and thus throttled uniformly.
Vorzugsweise sind die Drosselstege im Bereich der zweiten Mittelachse miteinander verbunden und am gegenüberliegenden Ende stehen die Drosselstege mit einem zylindrischen Ring miteinander in Verbindung. Der zylindrische Ring kommt dann vorzugsweise in Kontakt mit der besagten Lagerstelle, in welcher die Drossel gelagert ist.Preferably, the throttle webs are connected to each other in the region of the second central axis and at the opposite end of the throttle webs are connected to each other with a cylindrical ring. The cylindrical ring is then preferably in contact with said bearing point, in which the throttle is mounted.
Vorzugsweise weist das Drosselelement in einem in Einbaulage unten liegenden Bereich eine Sperrwand aufweist, welche dem Spülstrom entgegensteht. Die Sperrwand bildet einen geschlossenen Querschnitt und stellt dem Spülwasser einen entsprechenden Widerstand entgegen. Die Sperrwand hat insbesondere den Vorteil, dass bei Auslösen des Spülstroms heranschiessendes Wasser aus dem Spülkasten nach der Umlenkung im Rohrbogen bis auf die Höhe der Sperrwand gestaut wird und erst dann weiterfliessen kann. Der ersten Volumenstromspitze nach dem Auslösen einer Spülung wird durch die Sperrwand ein erhöhter Widerstand entgegengestellt, wodurch es zu einer leichten Stauung vor dem Drosselelement kommt. Durch diese Stauung kann eine Art Vollfüllung des Querschnittes des Rohrs im Bereich des Drosselelementes erreicht werden, wobei dies für die Strömung, nach erfolgter Drosselung, von grossem Vorteil ist. Es kommt zu einer Harmonisierung der Strömung.Preferably, the throttle element has a blocking wall in a region lying below in the installation position, which barrier wall opposes the flushing flow. The barrier wall forms a closed cross-section and provides the flushing water with a corresponding resistance. The barrier wall has the particular advantage that when the trigger Rinsing flow of incoming water from the cistern after the deflection in the pipe bend is dammed up to the height of the barrier wall and only then can continue to flow. The first volume flow peak after the triggering of a purge is provided by the barrier wall, an increased resistance, resulting in a slight stagnation in front of the throttle element. By this stowage, a kind of full filling of the cross section of the tube in the region of the throttle element can be achieved, and this is for the flow, after throttling, of great advantage. It comes to a harmonization of the flow.
Vorzugsweise ragt die Sperrwand im Wesentlichen bis maximal bis in die Mitte des zweiten Rohrabschnittes ein. Das heisst, die Sperrwand erstreckt sich von der Innenwand des zweiten Rohrabschnittes im Wesentlichen bis maximal auf die Mittelachse des zweiten Rohrabschnittes.Preferably, the barrier wall protrudes substantially to a maximum of up to the middle of the second pipe section. That is, the barrier wall extends from the inner wall of the second pipe section substantially to at most on the central axis of the second pipe section.
Die Sperrwand kann unterschiedliche Formen aufweisen. Vorzugsweise erstreckt sich die Sperrwand von der zweiten Mittelachse radial mit zwei Seitenkanten nach aussen, wobei sich die Sperrwand über die Fläche zwischen den Seitenkanten erstreckt. Der Winkel zwischen den Seitenkanten liegt zwischen 60° bis 120°, insbesondere bei 90°. Die beiden Seitenkanten stehen in Einbaulage derart, dass der Winkel zwischen der ersten Seitenkante und einer in der Vertikalen durch die Mittelachse sich erstreckende Achse und der Winkel zwischen der zweiten Seitenkante und der besagten Achse gleich ist.The barrier wall can have different shapes. Preferably, the barrier wall extends radially outwardly from the second center axis with two side edges, the barrier wall extending over the surface between the side edges. The angle between the side edges is between 60 ° to 120 °, in particular at 90 °. The two side edges are in the installed position such that the angle between the first side edge and a vertical axis extending through the central axis and the angle between the second side edge and the said axis is equal.
Alternativ erstreckt sich die Sperrwand besonders bevorzugt über ein Kreissegment ausgehend von der zweiten Mittelachse, wobei das Kreissegment einen Öffnungswinkel im Bereich von 60° bis 120°, insbesondere bei 90°, aufweist.Alternatively, the barrier wall particularly preferably extends over a circle segment starting from the second central axis, wherein the circular segment has an opening angle in the range of 60 ° to 120 °, in particular at 90 °.
Vorzugsweise erstreckt sich beim Drosselelement mit den Drosselstegen ein Segment der Sperrwand jeweils über den Zwischenraum zwischen zwei benachbarten Drosselstegen. Die Drosselwand kann aus einem oder mehreren Segmenten bestehen.Preferably, in the case of the throttle element with the throttle webs, a segment of the barrier wall extends in each case over the intermediate space between two adjacent throttle webs. The throttle wall may consist of one or more segments.
Eine Sanitärartikelanordnung umfasst eine Spülvorrichtung nach obiger Beschreibung und einen Sanitärartikel, insbesondere ein Urinal oder eine Klosettschüssel, wobei der zweite Rohrabschnitt direkt oder indirekt über ein Verbindungsrohr in den Sanitärartikel mündet.A sanitary article arrangement comprises a flushing device as described above and a sanitary article, in particular a urinal or a lavatory bowl, wherein the second pipe section opens directly or indirectly via a connecting pipe in the sanitary article.
Aufgrund der Anordnung des Drosselelementes im Bereich des Rohrbogens bzw. in einem kleinen Abstand zum Rohrbogen, ist das Drosselelement im zweiten Rohrabschnitt möglichst weit entfernt von der mindestens einen Austrittsöffnung in den Sanitärartikel angeordnet ist. Dies hat den Vorteil, dass sich die Strömung im Verbindungsrohr nach erfolgter Drosselung normalisieren kann und somit kontrollierter aus den Austrittsöffnung austreten kann.Due to the arrangement of the throttle element in the region of the pipe bend or at a small distance from the pipe bend, the throttle element in the second pipe section is located as far away from the at least one outlet opening in the sanitary article. This has the advantage that the flow in the connecting pipe can be normalized after throttling and thus can emerge more controlled from the outlet opening.
Vorzugsweise schliesst sich dem Verbindungsrohr ein Strömungsverteiler an, der den Spülstrom an die gewünschten Stellen im Sanitärartikel leitet.Preferably, a flow distributor connects to the connecting pipe, which directs the purge flow to the desired locations in the sanitary article.

Das Spülrohr 3 umfasst im Wesentlichen einen ersten Rohrabschnitt 4, einen sich dem ersten Rohrabschnitt 4 anschliessenden Rohrbogen 5 und einen sich dem Rohrbogen 5 anschliessenden zweiten Rohrabschnitt 6 mit einem Rohraustritt 7. Der erste Rohrabschnitt 5 schliesst sich dem Spülkasten 2 an und verläuft entlang einer ersten Mittelachse M1. In Einbaulage verläuft die erste Mittelachse M1 in der Vertikalen, also in Richtung der Schwerkraft. Der Rohrbogen 5 lenkt das Spülrohr 3 im Wesentlichen rechtwinklig um. Der zweite Rohrabschnitt 6 erstreckt sich entlang einer zweiten Mittelachse M2, welche in Einbaulage gesehen im Wesentlichen in der Horizontalen, also im Wesentlichen rechtwinklig zur Schwerkraft, verläuft. Die erste Mittelachse M1 steht im Wesentlichen rechtwinklig zur zweiten Mittelachse M2.The
Der zweite Rohrabschnitt 6 ist derart ausgebildet, dass dieser in ein Verbindungsrohr 22 mündet. Das Verbindungsrohr 22 wird zum Sanitärartikel 18 geführt. Das Verbindungsrohr 22 erstreckt sich entlang der zweiten Mittelachse M2 und liegt im Wesentlichen in der Horizontalen.The
Das Drosselelement 8 ist, wie bereits erwähnt, im Spühlrohr 3 angeordnet. Das Drosselelement 8 liegt im zweiten Rohrabschnitt 6. Das Drosselelement 8 ist in einem kurzen Abstand A zum geometrischen Rohrbogenende 9 des Rohrbogens 5 angeordnet. Das heisst, das Drosselelement 8 steht nahe zum geometrischen Rohrbogenende 9 des Rohrbogens 5. Besonders bevorzugt ist das Drosselelement 8 unmittelbar beim geometrischen Rohrbogenende 9 angeordnet. Die Anordnung des Drosselelementes 8 im kurzen Abstand A zum geometrischen Rohrbogenende 9 des Rohrbogens 5 wird in den
Dem Rohrbogen 5 schliesst sich direkt der zweite Rohrabschnitt 6 an. Aufgrund von dieser direkten Fortsetzung handelt es sich beim Ende des Rohrbogens 9 nicht um eine physisch vorhandenes Ende, weshalb das Rohrbogenende 9 als geometrisches Rohrbogenende 9 bezeichnet wird.The
Das geometrische Rohrbogenende 9 liegt in einer Referenzebene RE. Die Referenzebene RE ist rechtwinklig zur zweiten Mittelachse M2 orientiert und erstreckt sich durch den Endpunkt einer mittig durch den Rohrbogen 5 verlaufenden Bogenlinie. Die mittig durch den Rohrbogen 5 verlaufende Bogenlinie bildet dabei die Mittelachse durch den Rohrbogen 5 hindurch. Der Endpunkt der Bogenlinie liegt dabei am Ende des Rohrbogens 5. Der Endpunkt der Bogenlinie ist mit dem Bezugszeichen B versehen. Die Bogenlinie selbst trägt das Bezugszeichen L. Mit anderen Worten gesagt liegt das geometrische Rohrbogenende 9 dort, wo sich der zweite Rohrabschnitt 6 dem Rohrbogen 5 anschliesst.The geometrical
Der Abstand A kann verschiedenartig definiert sein. Wichtig ist, dass der Abstand A zwischen dem geometrischen Rohrbogenende 9 des Rohrbogens 5 und dem Drosselelement 8 möglichst klein ist. Das heisst, das Drosselelement 8 soll möglichst nah zum Rohrbogen 5 stehen. In einer Ausführungsform entspricht der Abstand A maximal dem Durchmesser des zweiten Rohrabschnittes 6. In einer bevorzugten anderen Ausführungsform entspricht der Abstand A maximal 50% des Durchmessers des zweiten Rohrabschnittes 6. In einer dritten Ausführungsform ist Abstand A maximal 25% des Durchmessers des zweiten Rohrabschnittes 6. Bezüglich einer physischen Grösse kann gesagt werden, dass der Abstand A im Bereich von 0 - 40mm liegt.The distance A can be defined in various ways. It is important that the distance A between the geometrical

Das heisst, beim Drosselelement 8 handelt es sich vorzugsweise um ein vom Spülrohr 3 separat ausgebildetes Element, das in den zweiten Rohrabschnitt 6 des Spülrohrs 3 einsetzbar ist. Hierfür weist der zweite Rohrabschnitt 6 eine Lagerstelle 11 für das Drosselelement 8 auf. Das Drosselelement 8 ist vorzugsweise drehfest in der Lagerstelle 11 gelagert. Hierzu weist das Drosselelement 8 und die Lagerstelle 11 in der gezeigten Ausführungsform eine Nut- und Kammverbindung 29 auf. Andere Ausführungen sind auch denkbar.

Der in Radius RI des Rohrbogens ist in der gezeigten Ausführungsform im Wesentlichen konstant. Durch die Veränderung des Aussenradius RA des Rohrbogens 5 kann die Strömung durch den Rohrbogen 5 ebenfalls weiter positiv beeinflusst bzw. optimiert werden. Andere Ausbildungen sind auch denkbar.In the embodiment shown, the outer radius RA of the
Das Drosselelement 8 stellt eine Querschnittsverengung des zweiten Rohrabschnittes 6 bereit. Die Querschnittsverengung des Durchmessers D des zweiten Rohrabschnittes 6 ist im Bereich von 5% bis 30%, insbesondere im Bereich von 10% bis 25%, das heisst, der Querschnitt wird um den entsprechenden Prozentbereich verkleinert.The
