Description

Die Erfindung bezieht sich auf einen Klosettkörper gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a toilet body according to the preamble of patent claim 1.

Es gibt zahlreiche bekannte Dusch-WCs, welche eine Unterduschvorrichtung mit einem Duscharm und einem Boiler umfassen. Das im Boiler erhitzte Wasser wird dem Duscharm zugefügt und über die Düse abgegeben. Zum Entkalken von solchen Vorrichtungen wird dem Boiler Entkalkungsmittel zugefügt, wobei beim Entkalkungsvorgang das Entkalkungsmittel enthaltende Wasser vom Boiler durch das gesamte System (Ventile, Schläuche etc.) bis zur Düsenöffnung geführt wird, so dass die gesamte Vorrichtung entkalkt werden kann.There are numerous known shower toilets which include an under-shower device with a shower arm and a boiler. The water heated in the boiler is added to the shower arm and released through the nozzle. To descale such devices, descaling agent is added to the boiler. During the descaling process, the water containing the descaling agent is led from the boiler through the entire system (valves, hoses, etc.) to the nozzle opening, so that the entire device can be descaled.

Aus der WO 2015/143571 TREMP ist eine ein Entkalkungsmittel enthaltende Kapsel bekannt, welche am vorderen Ende des Duscharms montiert werden kann, so dass beim Entkalkungsvorgang Entkalkungsmittel enthaltendes Wasser vom Duscharm über das gesamtes System (Duscharm, Ventile, Pumpe, Boiler etc.) fliesst und anschliessend über den Duscharm in den Klosettkörper abgegeben wird. Allerdings benötigt diese Art der Entkalkung eine speziell dafür vorgesehene Kapsel, welche mit dem Duscharm kompatibel sein muss. Nachteilig bei der Entkalkung mittels der Kapsel ist das aufwändige Handling. Der Duscharm muss ausgefahren werden, dann muss die Duschdüse abgenommen und die Kapsel aufgesetzt werden. Nach dem Entkalkungsprogramm (ca. 45 min) muss der Vorgang in der umgekehrten Reihenfolge wiederholt werden. Die weiteren Nachteile sind darin zu sehen, das bei diesem Handling der Benutzer in die Schmutzzone greifen muss und das Gerät für die Entkalkungsfunktion mit einer Rückführleitung ausgestattet sein muss, welche einen gewissen Platz benötigt, mehrere Schnittstellen aufweist, die auch einmal undicht werden können und ziemlich kostspielig ist.From the WO 2015/143571 TREMP is a capsule containing a descaling agent, which can be mounted at the front end of the shower arm, so that during the descaling process, water containing descaling agent flows from the shower arm over the entire system (shower arm, valves, pump, boiler, etc.) and then over the shower arm the toilet body is released. However, this type of descaling requires a specially designed capsule, which must be compatible with the shower arm. The disadvantage of descaling using the capsule is that it is difficult to handle. The shower arm must be extended, then the shower nozzle must be removed and the capsule must be put on. After the descaling program (approx. 45 minutes), the process must be repeated in the reverse order. The further disadvantages are that with this handling the user has to reach into the dirty zone and the device for the descaling function must be equipped with a return line, which requires a certain amount of space, has several interfaces that can sometimes leak and quite a bit is costly.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, einen Klosettkörper zu schaffen, welcher ein vereinfachtes Einfüllen eines Entkalkungsmittels in einen Boiler des WC's ermöglicht ohne dass der Benutzer in die Schmutzzone greifen muss und ohne dass das Ende des Entkalkungsprogramm abgewartet werden muss.The invention aims to provide a remedy here. The invention is based on the object of creating a toilet body which enables a simplified filling of a descaling agent into a boiler of the toilet without the user having to go into it The dirt zone must be accessed and without having to wait for the end of the descaling program.

Die Erfindung löst die gestellte Aufgabe mit einem Klosettkörper, welcher die Merkmale gemäss Anspruch 1 aufweist, sowie einem Verfahren, welches die Merkmale des Anspruchs 9 aufweist.The invention solves the problem with a toilet body which has the features according to claim 1 and a method which has the features of claim 9.

Die durch die Erfindung erreichten Vorteile sind im Wesentlichen darin zu sehen, dass beim erfindungsgemässen Klosettkörper dank seiner Öffnung, welche sich durch die Aussenfläche hindurch in die Kavität erstreckt, das Entkalkungsmittel direkt in den Boiler für das Dusch-WC befördert werden kann. Somit ist es möglich die Dimensionen des Dusch-WCs klein zu halten und auf zusätzliche Funktionen (Rückführleitung) zu verzichten.The advantages achieved by the invention can essentially be seen in the fact that in the toilet body according to the invention, thanks to its opening, which extends through the outer surface into the cavity, the descaling agent can be transported directly into the boiler for the shower toilet. This makes it possible to keep the dimensions of the shower toilet small and forego additional functions (return line).

Weitere vorteilhafte Ausgestaltungen der Erfindung können wie folgt kommentiert werden:
In einer speziellen Form verläuft der Kanal im Wesentlichen parallel zur Oberseite. Der Vorteil des parallel zur Oberseite verlaufenden Kanals gegenüber einem senkrecht zur Oberseite verlaufenden Kanal ist im Wesentlichen darin zu sehen, dass die Oberfläche eines Klosetts öfters durch Urin und Schmutzwasser verunreinigt wird, wobei die seitliche Öffnung ausserhalb des Urin- und Schmutzwassersbereich liegt. Da eine seitliche Öffnung weniger sichtbar als die in der Oberseite liegende ist, bietet eine solche Ausführungsform auch einen ästhetischen Vorteil.Further advantageous embodiments of the invention can be commented on as follows:
In a special shape, the channel runs essentially parallel to the top. The advantage of the channel running parallel to the top compared to a channel running perpendicular to the top is essentially that the surface of a toilet is often contaminated by urine and dirty water, with the side opening being outside the urine and dirty water area. Since a side opening is less visible than the one in the top, such an embodiment also offers an aesthetic advantage.

In einer weiteren Ausführungsform ist der Kanal reversibel verschliessbar. Dadurch wird die Verunreinigung des Wassers im Boiler vermieden und die Reinigung der Aussenfläche des Klosettkörpers vereinfacht.In a further embodiment, the channel can be reversibly closed. This prevents contamination of the water in the boiler and simplifies the cleaning of the outer surface of the toilet body.

In einer besonderen Variante weist der der Kanal eine runde Querschnittsfläche auf.In a special variant, the channel has a round cross-sectional area.

In einer speziellen Variante weist der Kanal einen Einsatz mit einer schlitzförmigen Öffnung auf. Die Fläche des Querschnitts der schlitzförmigen, vorzugsweise rechteckigen, Öffnung liegt zweckmässigerweise im Bereich von 3 bis 5 cm2.In a special variant, the channel has an insert with a slot-shaped opening. The area of the cross section of the slot-shaped, preferably rectangular, opening is expediently in the range of 3 to 5 cm 2 .

In einer Variante weist der Kanal über seine Gesamtlänge eine Minimalquerschnittfläche auf, welche mindestens 4 cm2, vorzugsweise mindestens 12 cm2 beträgt.In one variant, the channel has a minimum cross-sectional area over its entire length, which is at least 4 cm 2 , preferably at least 12 cm 2 .

In einer zusätzlichen Variante weist der Kanal über seine Gesamtlänge eine Maximalquerschnittfläche auf, welche maximal 20 cm2, vorzugsweise maximal 15 cm2 beträgt.In an additional variant, the channel has a maximum cross-sectional area over its entire length, which is a maximum of 20 cm 2 , preferably a maximum of 15 cm 2 .

In einer weiteren Variante weist der Kanal über seine Gesamtlänge einen minimalen Durchmesser auf, welcher mindestens 2 cm, vorzugsweise mindestens 3 cm, typischerweise 4 cm beträgt.In a further variant, the channel has a minimum diameter over its entire length, which is at least 2 cm, preferably at least 3 cm, typically 4 cm.

In einer weiteren Variante weist der Kanal über seine Gesamtlänge einen maximalen Durchmesser auf, welcher maximal 6 cm, vorzugsweise maximal 5 cm beträgt.In a further variant, the channel has a maximum diameter over its entire length, which is a maximum of 6 cm, preferably a maximum of 5 cm.

In einer besonderen Ausführungsform weist der Kanal über seine Gesamtlänge eine konstante Querschnittfläche auf.In a special embodiment, the channel has a constant cross-sectional area over its entire length.

In einer weiteren Ausführungsform weist der Kanal über seine Gesamtlänge einen konstanten Durchmesser auf.In a further embodiment, the channel has a constant diameter over its entire length.

In einer speziellen Ausführungsform ist der Boiler mindestens teilweise in der Kavität positioniert.In a special embodiment, the boiler is at least partially positioned in the cavity.

In einer weiteren Ausführungsform umfasst der Boiler eine Frischwasserzufuhröffnung und eine Austrittsöffnung.In a further embodiment, the boiler comprises a fresh water supply opening and an outlet opening.

In einer weiteren Ausführungsform ist die Entkalkungsmittelaufnahmeöffnung gegen die Oberseite hin offen.In a further embodiment, the descaling agent receiving opening is open towards the top.

Ein erfindungsgemässes Verfahren zum Entkalken eines Boilers des erfindungsgemässen Klosettkörpers umfasst die Schritte gemäss Anspruch 9.A method according to the invention for descaling a boiler of the toilet body according to the invention comprises the steps according to claim 9.

In einer weiteren Ausführungsform umfasst das Verfahren das Öffnen des verschlossenen Kanals vor dem Befördern des Entkalkungsmittels.In a further embodiment, the method includes opening the closed channel before conveying the descaling agent.

In einer besonderen Ausführungsform des Verfahrens erfolgt die Aktivierung des Entkalkungsvorgangs anhand der Leitfähigkeit des Wassers im Boiler. Dabei wird anhand der Messung der Leitfähigkeit des Wassers festgestellt, ob sich das Entkalkungsmittel im Wasser des Boilers befindet.In a special embodiment of the method, the descaling process is activated based on the conductivity of the water in the boiler. By measuring the conductivity of the water, it is determined whether the descaling agent is in the water in the boiler.

In einer weiteren Ausführungsform des Verfahrens erfolgt die Aktivierung des Entkalkungsvorgangs manuell durch den Benutzer. Dabei kann der Benutzer den Entkalkungsvorgang über eine Taste oder eine Fernsteuerung, z.B. eine App auf einem Smartphone auslösen.In a further embodiment of the method, the descaling process is activated manually by the user. The user can trigger the descaling process using a button or a remote control, e.g. an app on a smartphone.

In einer anderen Ausführungsform erfolgt die Aktivierung des Entkalkungsvorgangs mittels eines Sensors. Der Sensor kann aus einer Lichtschranke oder einem Schalter bestehen, der die Einführung des Entkalkungsmittels in den Kanal erkennt.In another embodiment, the descaling process is activated using a sensor. The sensor can consist of a light barrier or a switch that detects the introduction of the descaling agent into the channel.

In einer weiteren Ausführungsform befindet sich der Sensor sich im Boiler. Dank dem im Boiler angeordneten Sensor wird anhand der veränderten Leitfähigkeit des im Boiler vorhandenen, mit dem Entkalkungsmittel versetzten Wassers festgestellt, dass das Entkalkungsmittel dem Wasser im Boiler zugefügt wurde, so dass der Entkalkungsvorgang aktiviert werden kann.In a further embodiment, the sensor is located in the boiler. Thanks to the sensor arranged in the boiler, the changed conductivity of the water in the boiler containing the descaling agent is used to determine that the descaling agent has been added to the water in the boiler, so that the descaling process can be activated.

In einer anderen Ausführungsform befindet sich der Sensor im Kanal. Durch diese Ausführungsform ist es möglich auf dem Weg, welcher vom Entkalkungsmittel (z.B. Tab) zurückgelegt wird, mittels des Sensors (Schalter, Lichtschranke) das erfolgte Befördern des Entkalkungsmittels in den Boiler festzuhalten, so dass das Entkalkungsvorgang aktiviert werden kann.In another embodiment, the sensor is located in the channel. This embodiment makes it possible to record the transport of the descaling agent into the boiler using the sensor (switch, light barrier) on the path traveled by the descaling agent (e.g. tab), so that the descaling process can be activated.

Durch die Aktivierung des Entkalkungsvorgangs wird das entkalkungsmittelhaltige Wasser aus dem Boiler in den Schüsselhohlraum befördert. Das Befördern des entkalkungsmittelhaltigen Wasser erfolgt auf dem gleichen Weg mittels der gleichen Elemente, die auch für das normale Duschen benötigt werden (Pumpe / Duscharm). Im Gegensatz zum normalen Duschvorgang wird bei dem Entkalkungsvorgang der Duscharm nicht ausgefahren, so dass die Flüssigkeit zwischen der Blende und der Düse des Duscharms herausströmt.By activating the descaling process, the water containing descaling agent is transported from the boiler into the bowl cavity. The water containing descaling agent is conveyed in the same way using the same elements that are required for normal showering (pump/shower arm). In contrast to the normal showering process, the shower arm is not extended during the descaling process, so that the liquid flows out between the cover and the shower arm nozzle.

In einer weiteren Ausführungsform des Verfahrens liegt das Entkalkungsmittel in tablettierter Form vor. Die tablettierte Form des Entkalkungsmittels garantiert eine sicherere Handhabung im Vergleich zu flüssigen oder pulverförmigen Mitteln. Ein pulverförmiges Mittel würde einen schrägen Kanal oder einen Einschiebemechanismus benötigen. Flüssige Mittel haben sich als zu wenig konzentriert erweisen, so dass die erforderliche Menge deutlich zu hoch wäre, zudem besteht die Gefahr, dass das flüssige Mittel in unkontrollierter Weise wegfliesst.In a further embodiment of the method, the descaling agent is in tablet form. The tableted form of the descaling agent guarantees safer handling compared to liquid or powdered agents. A powdered agent would require a slanted channel or push-in mechanism. Liquid funds have proven to be insufficiently concentrated, so that the required amount would be significantly too high, and there is also the risk that the liquid funds will flow away in an uncontrolled manner.
