Description

Die Erfindung betrifft eine selbstreinigende Toilette, die eine an eine Spülvorrichtung angeschlossene Toilettenschüssel mit hochklappbarem Toilettendeckel und Sitzring umfasst.The invention relates to a self-cleaning toilet comprising a connected to a flushing toilet bowl with hinged toilet lid and seat ring.

Die bekannten, auch als Wasserklosett oder WC bezeichneten Toiletten mit Wasserspülung weisen eine aus Porzellan bestehende, als Flach- oder Tiefspüler ausgebildete Toilettenschüssel auf. Der obere Rand der Toilettenschüssel ist mit einem hochklappbaren Sitzring (Toilettenbrille) abgedeckt. Auf dem Sitzring ruht ein ebenfalls schwenkbar an der Toilettenschüssel angelenkter, das heißt hochklappbarer Toilettendeckel. Die bei der Benutzung in die Toilettenschüssel gelangenden menschlichen Ausscheidungen werden mit Hilfe der Wasserspülung über einen in der Toilettenschüssel ausgebildeten Siphon in die Kanalisation gespült. Das Spülwasser mündet am oberen Innenrand der Toilettenschüssel, um gleichzeitig die gegebenenfalls verschmutzten Innenflächen der Toilettenschüssel zu reinigen. Die Wasserzufuhr erfolgt über die Freigabe eines in einem Spülkasten bevorrateten Wasserreservoirs oder durch unmittelbaren Anschluss der Toilettenschüssel an ein Wasserleitungsnetz, wobei der Spülvorgang durch Betätigen eines Druckspülers eingeleitet wird. Mit dem an den Innenflächen der Toilettenschüssel ablaufendem Spülwasser gelingt es oftmals nicht, anhaftende Exkremente abzuspülen, und zwar auch nicht nach zwei- oder mehrfacher, mit einem hohen Wasserverbrauch verbundener Betätigung der Wasserspülung. In diesem Fall ist die aufwändige und für den Benutzer unangenehme Benutzung einer Toilettenbürste erforderlich, die zudem unhygienisch ist, da Fäkalienreste an der Toilettenbürste haften bleiben können.The well-known, also known as water closet or toilet toilets with water flush have a porcelain existing, designed as a flat or Tiefspüler toilet bowl. The upper edge of the toilet bowl is covered with a fold-up seat ring (toilet seat). On the seat ring rests also pivotally hinged on the toilet bowl, that is hinged toilet lid. The human waste discharged into the toilet bowl during use is flushed into the sewage system with the aid of water flushing via a siphon formed in the toilet bowl. The rinse water opens at the upper inner edge of the toilet bowl to simultaneously clean the possibly contaminated inner surfaces of the toilet bowl. The water is supplied via the release of a stocked in a cistern water reservoir or by directly connecting the toilet bowl to a water pipe network, the flushing process is initiated by pressing a flush valve. With the rinsing water running off the inner surfaces of the toilet bowl, it is often not possible to rinse off adhering excrements, even after two or more operations of the water rinse, which are associated with a high water consumption. In this case, the elaborate and unpleasant for the user use of a toilet brush is required, which is also unhygienic because fecal matter residues can adhere to the toilet brush.

Noch weitaus schwieriger gestaltet sich die Reinigung von für die Öffentlichkeit und einem unkontrollierten Personenkreis zugänglichen Toiletten, in denen extrem starke Verschmutzungen auftreten können und nach jeder Benutzung eine ordnungsgemäße manuelle Reinigung der Toilettenschüssel und der Sitzfläche dringend geboten ist. Der dazu erforderliche personelle und finanzielle Aufwand ist hoch und die entsprechenden Mittel stehen in der Regel nicht zur Verfügung.Even more difficult is the cleaning of accessible to the public and an uncontrolled group of people toilets in which extremely heavy soiling may occur and after each use Proper manual cleaning of the toilet bowl and seat is urgently required. The required personnel and financial expenditure is high and the corresponding funds are usually not available.

Gleichzeitig mit dem Reinigen der Toilettenschüssel 1 wird über die im zweiten Ringkanal 16 ausgebildeten Spray- und Luftdüsen 17 zunächst eine Reinigungsflüssigkeit auf die Oberfläche des Sitzrings 4 gesprüht. Mit einem anschließenden Warmluftstrahl wird der Sitzring 4 wieder getrocknet. Nachdem der Reinigungsdüsenkörper 10 wieder in seine Ausgangsposition innerhalb des Toilettendeckels 5 zurückgefahren ist, fährt der Toilettendeckel 5 in die hochgeklappte Position, der Zugang zum Toilettenraum wird freigegeben und die vollständig gereinigte Toilette kann erneut benutzt werden. Der gesamte Reinigungsvorgang läuft über eine dem zum Antrieb des Toilettendeckels und des Reinigungsdüsenkörpers dienenden Motor und den zum Zuführen der Reinigungsflüssigkeit vorgesehenen Pumpen sowie der Warmluftzufuhr, dem Spülmechanismus und der Türöffnung des Toilettenraums zugeordnete Steuerelektronik automatisch ab, und zwar mit geringem Zeitaufwand und niedrigem Wasserverbrauch.Simultaneously with the cleaning of the toilet bowl 1, a cleaning liquid is first sprayed onto the surface of the seat ring 4 via the spray and air nozzles 17 formed in the second annular channel 16. With a subsequent warm air jet, the seat ring 4 is dried again. After the cleaning nozzle body 10 is moved back to its original position within the toilet lid 5, the toilet lid 5 moves into the raised position, the access to the toilet room is released and the fully cleaned toilet can be used again. The entire cleaning process automatically proceeds via a motor serving for driving the toilet lid and the cleaning nozzle body and the pumps provided for supplying the cleaning liquid, the control electronics associated with the flushing mechanism and the door opening of the toilet room, with little expenditure of time and low water consumption.
