In den.Fig. ist rein prinzipiell und vom Aufbau jeweils die gleiche Toilettenschüssel 10 bestimmt für eine Toiletten-Vakuumanlage dargestellt. Die Toilettenschüssel 10 besteht aus einem doppelwandigen Körper 11 und weist in ihrem Tiefstpunkt, also im Bodenbereich 12, einen Anschluss zu einer Vakuum-Leitung 14 auf, in der sich ein Absperrventil 16 befindet, das in gewohnter Weise dann eine Verbindung zu der Toilettenschüssel 10, also deren Innenbereich 18, herstellt, wenn angesammelte Flüssigkeit und Feststoffe abgesaugt werden sollen. Insoweit wird auf hinlänglich bekannte und der Vakuum-Technik zu entnehmende Steuereinrichtungen verwiesen. Im Bereich des oberen Randes 20 der Toilettenschüssel 10 beabstandet zu diesem sind Düsen 22, 23 angeordnet, um die Innenfläche 24 der Toilettenschüssel 10 ausspülen zu können.In the.Fig. is purely in principle and the construction of the
Um sicherzustellen, dass dann, wenn das Absperrventil 16 nicht öffnet oder bei geöffnetem Absperrventil 16 die Toilettenschüssel 10 über die Absaugleitung 14 nicht entleert werden kann, in der Schüssel, also in dem Innenbereich 18 sich ansammelnde Flüssigkeiten nicht bis zu den Spüldüsen 22, 23 ansteigen kann, so dass diese nicht mit Schmutzwasser in Berührung gelangen können, ist im rückseitigen Bereich 26 der Schüssel 10 ein Überlauf 28 vorgesehen, der durch einen kammer- bzw. kanalförmigen Abschnitt bzw. eine Aussparung 30 gebildet wird, der seitlich in Taschen wie Befestigungstaschen 32, 34 übergeht, über die Flüssigkeit zwangsgeführt in den Sanitärraum läuft, in dem sich die Toilettenschüssel 10 befindet. Dabei weist der Überlauf 28 eine Öffnung 36 auf, deren oberer Rand 38 im Abstand H unterhalb der Düsen 22, 23 verläuft. Der Abstand H beläuft sich vorzugsweise auf in etwa 20 mm.To ensure that when the shut-off valve 16 does not open or when the shut-off valve 16 is open, the
Der kanal- bzw. kammerförmige Abschnitt 30 der Toilettenschüssel weist einen von der Öffnung 36 ausgehenden ansteigenden rinnenförmigen Boden 40 auf, wodurch sichergestellt wird, dass dann, wenn unbeabsichtigt Flüssigkeit in den Abschnitt 30 strömt, diese in den Bereich 18 der Toilettenschüssel 10 zurückströmen kann. Hierdurch erfolgt eine Art Selbstreinigung. Ferner sind die zu den seitlichen Taschen 30, 32 führenden Öffnungen der Aussparung 30 querschnittsmäßig derart ausgebildet, dass eine Reinigung des Kanals bzw. der Kammer, d. h. des Überlaufs 28 von Hand erfolgen kann. Die im Ausführungsbeispiel zu den Befestigungstaschen 32, 34 führenden Auslässe erstrecken sich dabei oberhalb des rinnenförmig ausgebildeten Bodens 40.The channel-shaped
Oberhalb der Öffnung 36 des Überlaufs 28 ist die Toilettenwandung 42 im Vergleich zu dem unterhalb der Öffnung 36 verlaufenden Bereich 44 vorspringend ausgebildet, wie insbesondere die Ansicht A in Fig. 3 verdeutlicht.Above the
Wie sich insbesondere aus den Fig. 6, 8 ergibt, ist durch die Geometrie und Höhenanordnung des Überlaufs 28 sichergestellt, dass dann, wenn die Toilettenschüssel 10 unzulässig mit Flüssigkeit gefüllt sein sollte, diese gezielt aus der Toilettenschüssel über den Überlauf 28 zu den Befestigungstaschen 32, 34 zum Bodenbereich des Sanitärraums geführt wird, in dem die Toilettenschüssel 10 angeordnet ist. Somit ist sichergestellt, dass die Düsen 22, 23 nicht mit dem Abwasser in Berührung kommen können.As is apparent in particular from FIGS. 6, 8, it is ensured by the geometry and height arrangement of the
Durch die Zwangsführung des überlaufenden Wassers in den Sanitärraum hinein kann keine Flüssigkeit hinter eine Vorwandinstallation oder in einen Hohlraum der Toilettenschüssel 10 bzw. deren Körpers gelangen, so dass nach erfolgtem Überlauf und Säuberung des Sanitärraums eine Geruchsbelästigung ausgeschlossen ist.Due to the forced operation of the overflowing water into the sanitary room, no liquid can reach behind a wall installation or into a cavity of the
Wie insbesondere aus der Ansicht A in Fig. 3 erkennbar ist, sind im oberen Randbereich des Toilettenkörpers 11 allein zwei Düsen 22, 23 vorgesehen, um über diese Reinigungsflüssigkeit zum Säubern der Innenfläche 24 der Toilettenschüssel 10, d.h. deren Körpers 11 zu versprühen. Dabei sind die Düsen 22, 23 diametral gegenüber und etwa mittig jeweils in jeder Längsseite angeordnet.As can be seen in particular from the view A in Fig. 3, two
Ungeachtet dessen ist jedoch sichergestellt, dass die Innenfläche 24 nahezu vollständig besprüht und damit gereinigt werden kann. Hierzu sind folgende Maßnahmen vorgesehen. Jede Düse 22, 23 besteht aus einem pilzförmigen Körper, der sich aus einem sich entlang der Innenfläche 24 im oberen Rand 20 der Toilettenschüssel 10 erstreckenden ersten Abschnitt 44 und einem zweiten sich in den Körper 11 hinein erstreckenden Abschnitt 46 zusammensetzt. Der zweite Abschnitt 46 wird von einem zentralen Kanal 48 durchsetzt, über den Spülflüssigkeit zuleitbar ist. Von dem Kanal 48 geht ein einen bogenförmigen Verlauf aufweisenden Schlitz 50 aus, der im Umfangsrand 52 des ersten Abschnitts 44 mündet. Dabei erstreckt sich der Austrittsschlitz 50 über einen Bogen, der vorzugsweise im Bereich von 160° bis 165° liegt und dem Bodenbereich der Schüssel 10 zugewandt ist. Die Erstreckung erfolgt dabei symmetrisch zur Vertikalachse 54, die senkrecht oder in etwa senkrecht zu einer Ebene verläuft, die von den Düsen 22, 23 aufgespannt wird und parallel zum oberen Rand 20 der Toilettenschüssel 10 verläuft.Regardless, however, it is ensured that the
Der Schlitz 50 geht in seinem jeweiligen Ende in eine Bohrung 56, 58 über, deren Durchmesser D größer als der Schlitz 50 in seiner Breite S ist. Dabei beträgt der Durchmesser in etwa das 1.8fache der Breite S des Schlitzes 50.The
Die Bohrungen 56, 58 gehen - wie der Austrittsschlitz 50 - von dem Kanal 48 aus, über den die Reinigungsflüssigkeit den Düsen 22, 23 zugeführt wird.The
Da die Bohrungen 56, 58 den Austrittsschlitz 52 in seiner jeweiligen radialen Begrenzung durchsetzen, schließen die Bohrungen 56, 58 einen Winkel α von in etwa 160 bis 165° ein.Since the
Der Schlitz 50 spannt eine Ebene auf, die geneigt zur Außen- bzw. Innenfläche 60, 62 des ersten Abschnitts 44 der Düse 22, 23 verläuft. Dabei wird ein Winkel β von in etwa 6° bis 7° eingeschlossen, wodurch sich der Schlitz 50 bei eingebauter Düse 22, 23 in Richtung der Innenfläche 24 der Toilettenschüssel 10 erstreckt.The
Die Bohrungen 56, 58 werden vorzugsweise durch Bohren ausgebildet, wobei der Schlitz 50 bis zu den Querbohrungen 56, 58 gefräst wird.The
Dadurch, dass der Schlitz 50 zu der Fläche 60 geneigt verläuft, tritt ersterer sehr nah an der inneren Begrenzungsfläche 60 aus, die ihrerseits zumindest abschnittsweise flächig an der Innenfläche 24 der Toilettenschüssel 10 anliegt. Hierdurch und durch die Bohrungen 56, 58 ergibt sich ein gutes Spülverhalten, das sicherstellt, dass die Toilettenschüssel 10 bzw. deren Innenfläche 24 im gewünschten Umfang gereinigt wird, also auch im erforderlichen Umfang am Randbereich zwischen den Düsen 22, 23.Characterized in that the
Aus der Darstellung nach Fig. 10 wird des Weiteren ersichtlich, dass die Bohrungen 56, 58 nicht mittig von dem Kanal 48 ausgehen, sondern in etwa von dessen dem Schlitz 50 fernliegenden Randbereich 64.From the illustration according to FIG. 10, it can further be seen that the
