Die Steuervorrichtung 35 besitzt ferner auch mindestens ein Bedienungselement, beispielsweise ein Sensorschalter 36, mit welchem der nachfolgend beschriebene Spülvorgang manuell ausgelöst werden kann.Finally, the water closet 1 still has one one block shown electronic control device 35 on, by the pivoting in and out of bowl 7 and Glasses 8 as well as the procedure described below Cleaning process fully or partially controlled automatically can be. A control circuit belongs to this control device 35 with electrical and / or electronic components for measuring, controlling and regulating. The control circuit is thereby with electrical not shown in the figures Lines with the swivel device and devices 20 and 31 and all other drivable and controllable parts of the water closet 1 connected. The individual electrical or Electronically controllable parts or elements are expedient also locked against each other depending on time and controllable. The control device 35 also has at least an operating element, for example a sensor switch 36, with which the rinsing process described below can be triggered manually.

Nachdem ein Ausführungsbeispiel der Erfindung im Detail beschrieben wurde, soll nun der zur Reinigung von Schüssel 7 und Brille 8 dienende Reinigungsvorgang näher erläutert werden.Having an embodiment of the invention in detail for cleaning bowl 7 and glasses 8 serving cleaning process will be explained in more detail.

Das in den Figuren 1 bis 4 dargestellte Wasserklosett 1 präsentiert sich seinem Benutzer in der Regel in der Gebrauchsstellung. Nach Gebrauch des Wasserklosetts 1 durch den Benutzer werden Schüssel 7 und Brille 8 automatisch oder durch Betätigung des Sensorschalters 36 in die Spülstellung verschwenkt, worauf mindestens ein Teil des Schüsselinhaltes in den Ablauf 10 hinein entleert und der eigentliche Reinigungsvorgang ausgelöst wird. Zur Reinigung wird die Reinigungsvorrichtung 20 mit Ihrer Haube 21 auf die Schüssel 7 bzw. Brille 8 gesetzt, so wie das in der Figur 2 dargestellt ist. Dabei wird der Reinigungsraum 31 so abgedichtet, dass das in diesen einzuleitende Spülwasser entlang der Dichtkante d abfliesst und in den Ablauf 10 gelangt oder gegebenenfalls vom Auffangbecken 21a der Haube 21 aufgenommen wird.The water closet 1 shown in FIGS. 1 to 4 usually presents itself to its user in the use position. After using the water closet 1 by the Users will bowl 7 and glasses 8 automatically or by actuating the sensor switch 36 into the rinsing position pivoted, whereupon at least part of the bowl contents emptied into the drain 10 and the actual cleaning process is triggered. The cleaning device is used for cleaning 20 with your hood 21 on the bowl 7 or glasses 8 set, as shown in Figure 2 is. The cleaning space 31 is sealed in such a way that the rinse water to be introduced into this along the sealing edge d flows off and reaches the drain 10 or, if necessary the hood 21 is received by the catch basin 21a.

Anschliessend werden die Brille 8 und die Innenwand der Schüssel 7 während einer ersten Reinigungsphase mit durch die Sprühdüsen 24, 25 und 26 hindurchgeleitetem Druckwasser abgespritzt und gereinigt, und zwar mit einem Druck von beispielsweise 1000 bis 3000 kPa und einem Düsenabstand von etwa 3 bis 10 cm. Während dieser Reinigungsphase wird die Reinigungsanlage 23 um die Achse 22 gedreht und der restliche Inhalt der Schüssel 7 in den Ablauf 10 hinein gespült.Then the glasses 8 and the inner wall of the Bowl 7 during the first cleaning phase Spray nozzles 24, 25 and 26 sprayed through pressurized water and cleaned, with a pressure of, for example 1000 to 3000 kPa and a nozzle spacing of about 3 to 10 cm. During this cleaning phase, the cleaning system 23 rotated about the axis 22 and the rest of the contents the bowl 7 flushed into the drain 10.

Während der sich über eine Zeitdauer von beispielsweise 5 bis 30 Sekunden erstreckenden ersten Reinigungsphase werden selbst hartnäckig an Brillenoberfläche oder Schüsselinnenwand haftende Verunreinigungen und Schmutzpartikel gelöst und eventuell zusammen mit anderen Grobteilen wie beispielsweise Klosettpapier in den Ablauf 10 geschwemmt. Gleichzeitig oder etwas später kann mit den Ventilatormitteln heisse Luft in den durch die Haube 21 und die Schüssel 7 begrenzten Reinigungsraum 31 geblasen werden, beispielsweise in den Mündungsstrahl der Düsen 24, 25 und 26, so dass sich mit dem so erwärmten oder erhitzten Druckwasser hartnäckig haftender Schmutz leichter von der Brille 8 oder von der Innenwand der Schüssel 7 lösen lässt. Hierbei können die Ventilatormittel auch so gesteuert werden, dass die Brillenoberfläche kurzzeitig, beispielsweise für 2 bis 30 Sekunden, auf eine über 100°C, vorzugsweise 150 - 200°C betragende Temperatur erhitzt wird, wodurch praktisch alle an der Brillenoberfläche vorhandenen Mikroorganismen zerstört werden.During the period of 5 up to 30 seconds first cleaning phase even stubborn on the surface of the glasses or inside the bowl adhering impurities and dirt particles and possibly together with other coarse parts such as Toilet paper washed into the drain 10. At the same time or a little later, hot air can get in with the fan means the cleaning space delimited by the hood 21 and the bowl 7 31 are blown, for example into the muzzle jet of the nozzles 24, 25 and 26, so that with the so heated or heated pressurized water stubbornly adherent Dirt more easily from the glasses 8 or from the inner wall of the Let bowl 7 loosen. Here, the fan means can also be controlled so that the surface of the glasses is briefly for example for 2 to 30 seconds, to an over 100 ° C, preferably 150-200 ° C temperature heated which means that practically everything on the surface of the glasses Microorganisms are destroyed.

Im Anschluss an die erste Reinigungsphase wird der Wasserzufluss abgebrochen und die Brille 8 sowie die Schüssel 7 in einer zweiten Reinigungsphase mit den Ventilatormitteln - trocken geblasen, und zwar mit kalter oder gegebenenfalls heisser Luft, so dass einem nachfolgenden Benutzer eine trokkene sanitäre Einrichtung zur Verfügung gestellt wird.After the first cleaning phase, the water inflow canceled and glasses 8 and bowl 7 in a second cleaning phase with the fan means - blown dry, with cold or if necessary hot air, so that a subsequent user a dry sanitary facility is provided.

Für den vorgängig beschriebenen Reinigungsvorgang benötigt der erfindungsgemässe Reinigungsmechanismus lediglich etwa 0,5 bis 3 Liter Wasser, also eine verhältnismässig kleine Wassermenge. Die zur Reinigung und Trocknung von Schüssel 7 und Brille 8 benötigte Zeit beträgt beispielsweise 0,5 bis 2 Minuten.Required for the cleaning process described above the cleaning mechanism according to the invention only about 0.5 to 3 liters of water, so a proportionate small amount of water. The for cleaning and drying of Bowl 7 and glasses 8 required time is for example 0.5 to 2 minutes.

Wie aus der Figur 2 ersichtlich ist, kommt das Auffangbecken 21a der Haube 21 während des Reinigungsvorganges unter das Wasserniveau n zu liegen. Es ist daher ein Wasserabfuhr-Mechanismus notwendig, der beim Herausschwenken der Schüssel 7 das Spülwasser vom Auffangbecken 21a in den Abfluss 10 fliessen lässt. Dies wird erfindungsgemäss durch den Abfluss-Schlauch 14 ermöglicht, der mit seinem einen Ende im Auffangbecken 21a sitzt und mit seinem anderen Ende in die Schüssel 7 mündet, wobei beim Herausschwenken der Schüssel 7 in die Gebrauchsstellung das Spülwasser zuerst nach oben transportiert wird, von wo es dann durch den Abfluss-Schlauch 14 in den Abfluss 10 fliessen kann.As can be seen from FIG. 2, the collecting basin comes 21a of the hood 21 during the cleaning process the water level n to be. It is therefore a water drainage mechanism necessary when swinging out the bowl 7 the rinsing water from the collecting basin 21a into the drain 10 lets flow. According to the invention, this is made possible by the drain hose 14 allows one end in the catch basin 21a sits and with its other end in the bowl 7 opens out, when the bowl 7 is swung out into the In the use position, the flushing water is first transported upwards from where it is then through the drain hose 14 in the drain 10 can flow.

Beim Verschwenken der Schüssel 7 in das Gehäuse 2 wird der vordere Teil des Schüsselrandes 7a nach oben und der hintere Teil des Schüsselrandes 7a nach unten bewegt, so dass die Schüssel 7 in der Spülstellung eine geneigte Lage einnimmt. Zum Verschwenken der Schüssel 7 dient - wie bereits erwähnt - eine Schwenkvorrichtung, beispielsweise eine Vorrichtung der in der Figur 5 dargestellten Art.When the bowl 7 is pivoted into the housing 2 the front part of the bowl rim 7a upwards and the rear Part of the bowl rim 7a is moved downward, so that the bowl 7 assumes an inclined position in the rinsing position. For pivoting the bowl 7 is used - as already mentioned - a swivel device, for example a device of the type shown in Figure 5.

Die in der Figur 5 nur schematisch dargestellte Schwenkvorrichtung 40 besitzt einen Elektromotor 41 mit einem Antriebsrad 42 und einem dazugehörigen Hebelarm 43. Letzterer ist mit seinen beiden Enden gelenkig mit dem Antriebsrad 42 und der Anlenkung 13 des Schüsselgehäuses 12 verbunden. Die Konstruktion der gelenkigen Verbindung ist nun derart gewählt, dass sich die Schüssel 7 durch die Drehung des Antriebsrades in Pfeilrichtung 44 von der Gebrauchsstellung in die Spülstellung und zurück verschwenken lässt. Durch diesen Schwenkmechanismus kann insbesondere auf eine Änderung der Drehrichtung der Antriebswelle vor jedem Ein- oder Ausschwenken verzichtet werden, was schliesslich eine sanfte und nahezu geräuschlose Schwenkbewegung zur Folge hat.The swivel device shown only schematically in FIG. 5 40 has an electric motor 41 with a drive wheel 42 and an associated lever arm 43. The latter is articulated with the drive wheel 42 at both ends and the linkage 13 of the bowl housing 12 connected. The Construction of the articulated connection is now chosen in such a way that the bowl 7 by the rotation of the drive wheel in the direction of arrow 44 from the position of use in swings the rinsing position and back. Through this Swivel mechanism can in particular to a change in Direction of rotation of the drive shaft before each swiveling in or out be dispensed with, which is ultimately a gentle and almost noiseless swiveling movement.

Das in der Figur 6 nur in der Gebrauchsstellung dargestellte und als ganzes mit 101 bezeichnete Wasserklosett ist im wesentlich gleich ausgebildet wie das anhand der Figuren 1 bis 4 beschriebene Wasserklosett 1, besitzt also ein Gehäuse 102, in welchem eine Schüssel 107 mit einer auf der Schüssel 107 angeordneten Brille 108 verschwenkbar eingesetzt ist.That shown in Figure 6 only in the use position and as a whole is a water closet designated 101 designed essentially the same as that based on FIGS to 4 described water closet 1, so has a housing 102, in which a bowl 107 with one on the bowl 107 arranged glasses 108 is pivotally inserted.
