Unter der Ausdrucksweise "dass das Abdeckelement die Spülwasserdüse teilweise abdeckt" wird verstanden, dass das Abdeckelement im Wesentlichen der Verschalung der Spülwasserdüse ihrer Gebrauchslage dient. Die Verschalung ist derart ausgebildet, dass die der mindestens eine Düsenausgang Spülwasser an den Sanitärartikel ungehindert vom Abdeckelement abgeben kann. Weiter dient das Abdeckelement zudem als Betätigungselement zur Bewegung der Spülwasserdüse von der Gebrauchslage in die Wartungslage und zurück.The expression "that the covering element partially covers the flushing water nozzle" is understood to mean that the covering element essentially serves to cover the flushing water nozzle in its position of use. The casing is designed in such a way that the at least one nozzle outlet can release rinsing water from the cover element to the sanitary article without hindrance. Furthermore, the cover element also serves as an actuating element for moving the flushing water nozzle from the usage position to the maintenance position and back.
Durch die Verbindung zwischen dem Abdeckelement und der Spülwasserdüse ergeht der Vorteil, dass für die Manipulation der Spülwasserdüse kein zusätzliches Element vorhanden sein muss. Der Benutzer kann über das Abdeckelement die entsprechenden Manipulationen ausführen.The connection between the cover element and the flushing water nozzle results in the Advantage that there is no need for an additional element to manipulate the flushing water nozzle. The user can carry out the corresponding manipulations via the cover element.
Weiter weist die Spülwasserdüse mindestens eine Rastlasche auf, welche mit einer im Innenraum des Leitungsstücks angeordnete Rasterhebung einen Eingriff eingeht, wobei die Rasterhebung näher zum vorderen Ende des Leitungsstückes liegt, derart dass die Spülwasserdüse aus dem Leitungsstück zu einem gewissen Grad herausziehbar und dass vor der vollständigen Entfernung der Spülwasserdüse aus dem Leitungsstück ein Eingriff zwischen Rastlasche und Rasterhebung bereitgestellt wird. Hierdurch wird verhindert, dass der Benutzer die Spülwasserdüse unbeabsichtigt vollständig aus dem Leitungsstück herauszieht. Der Benutzer kann den Einsatz vorzugsweise dennoch vollständig aus dem Kanal herausziehen, wenn der Rasteingriff zwischen Rasterhebung und Rastlasche überwunden wird.The flushing water nozzle also has at least one latching tab, which engages with a notched projection arranged in the interior of the line piece, with the notched projection being closer to the front end of the line piece, such that the flushing water nozzle can be pulled out of the line piece to a certain extent and that before the complete Removal of the flushing water nozzle from the piece of line an engagement between the locking tab and grid elevation is provided. This prevents the user from unintentionally pulling the flushing water nozzle completely out of the line piece. The user can preferably still pull the insert completely out of the channel when the locking engagement between the detent projection and the locking tab is overcome.
Weiter hat die Verbindung zwischen dem Abdeckelement und der Spülwasserdüse sowie die Verriegelung des Abdeckelements zum Sanitärartikel, insbesondere zum Leitungsstück, den Vorteil, dass keine Verriegelungsstruktur zwischen der Spülwasserdüse und dem Leitungsstück vorzusehen ist, was die Struktur der Spülwasserdüsenanordnung insgesamt vereinfacht. Die Verriegelung wird über das Abdeckelement bereitgestellt.Furthermore, the connection between the cover element and the flushing water nozzle and the locking of the cover element to the sanitary article, in particular to the line piece, has the advantage that no locking structure has to be provided between the flushing water nozzle and the line piece, which simplifies the structure of the flushing water nozzle arrangement overall. Locking is provided via the cover member.
Die Ausdrucksweise "einen Verriegelungsabschnitt" ist so zu verstehen, dass auch mehrere Verriegelungsabschnitte vorhanden sein können.The expression "a locking section" is to be understood in such a way that there can also be several locking sections.
Das Leitungsstück ist vorzugsweise ein in den Sanitärartikel einsetzbares Leitungsstück. Das Leitungsstück kann aber auch direkt am Sanitärartikel angeformt sein bzw. durch den Sanitärartikel bereitgestellt werden.The line piece is preferably a line piece that can be inserted into the sanitary article. However, the line piece can also be formed directly on the sanitary article or be provided by the sanitary article.
Gegenüber dem vorderen Ende weist das Leitungsstück ein hinteres Ende auf, über welches Wasser in den Innenraum bzw. in den Düsenkanal einströmen kann. Das hintere Ende kann mit einem Spülrohr verbunden werden oder liegt, wie unten beschrieben, in einem Zwischenrohr.Opposite the front end, the line piece has a rear end through which water can flow into the interior or into the nozzle channel. The rear end can be connected to a flushing tube or is in an intermediate tube as described below.
Vorzugsweise liegen die beiden Verriegelungsabschnitte ausserhalb des Innenraums des Leitungsstückes.The two locking sections are preferably located outside the interior of the line piece.
