Description

Die vorliegende Erfindung betrifft einen Einbauspülkasten gemäß dem Oberbegriff des Anspruchs 1. Derartige Einbauspülkästen sind im Stand der Technik in zahlreichen Varianten bekannt.The present invention relates to a built-in cistern according to the preamble of claim 1. Such built-in cisterns are known in the prior art in numerous variants.

So ist beispielsweise aus der EP 2 397 613 A1 ein Einbauspülkasten mit Feuchte- und Leckageschutz bekannt. Bei diesem Einbauspülkasten ist der Feuchte- und Leckageschutz als eine dem Einbauspülkasten und das Verbindungsrohr umgebende, flexible, wasserdichte Schutzhülle ausgebildet, wobei unterseitig an der Schutzhülle ein schlauchartiger Fortsatz mit mindestens einer unterseitigen Öffnung an dessen Ende ausgebildet ist. Nachteilig bei dieser Lösung ist jedoch, dass die relativ dünne Schutzhülle beim Einbau leicht beschädigt werden kann und solche Beschädigungen nicht leicht entdeckt werden können. Ein sicherer Leckageschutz ist somit nicht mit der wünschenswerten Zuverlässigkeit gewährleistet. Ein weiteres Beispiel findet sich in EP 1284327 .For example, from the EP 2 397 613 A1 a built-in cistern with moisture and leakage protection known. In this built-in cistern, the moisture and leakage protection is designed as a flexible, waterproof protective sheath surrounding the built-in cistern and the connecting pipe, a hose-like extension having at least one opening on the underside of its end being formed on the protective cover. A disadvantage of this solution, however, is that the relatively thin protective cover can easily be damaged during installation and such damage cannot be easily discovered. Safe leakage protection is therefore not guaranteed with the desirable reliability. Another example can be found in EP 1284327 ,

Aufgabe der Erfindung ist es daher, die sich aus dem Stand der Technik ergebenden Probleme zu lösen und insbesondere einen Einbauspülkasten mit einem besonders zuverlässigen Feuchte- und Leckageschutz bereitzustellen.The object of the invention is therefore to solve the problems arising from the prior art and in particular to provide a built-in cistern with particularly reliable protection against moisture and leakage.

Diese Aufgaben werden mit einem Einbauspülkasten gemäß den Merkmalen des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängig formulierten Patentansprüchen angegeben. Es ist darauf hinzuweisen, dass die in den abhängig formulierten Patentansprüchen aufgeführten Merkmale in beliebiger technologisch sinnvoller Weise miteinander kombiniert werden können und weitere Ausgestaltungen der Erfindung definieren. Darüber hinaus werden die in den Patentansprüchen angegebenen Merkmale in der Beschreibung näher präzisiert und erläutert, wobei weitere bevorzugte Ausführungsbeispiele der Erfindung dargestellt werden.These tasks are solved with a built-in cistern according to the features of claim 1. Further advantageous refinements of the invention are specified in the dependent claims. It should be pointed out that the features listed in the dependent claims can be combined with one another in any technologically meaningful manner and define further refinements of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, further preferred exemplary embodiments of the invention being illustrated.

Durch die erfindungsgemäße Verwendung einer formstabilen und wasserundurchlässigen Schale als Leckageschutzeinrichtung, welche den Einbauspülkasten zumindest teilweise umschließt, wird eine versehentliche Beschädigung der Leckageschutzeinrichtung bei der Montage wirksam verhindert. Während die im Stand der Technik bekannte Folie sehr leicht durch spitze Werkzeuge oder Schrauben beschädigt werden kann, ist dies bei einer formstabilen und beispielsweise aus Kunststoff gefertigten Schale nicht ohne weiteres möglich. Die Schale ist dazu so ausgebildet, dass sie den Einbauspülkasten an einer Rückseite zumindest teilweise umschließt. Gleiches gilt für innerhalb des Mauerwerks angeordnete Seitenbereiche und eine Unterseite des Einbauspülkastens, die ebenfalls zumindest teilweise von der Schale umschlossen sind. Lediglich die Vorderseite der Schale ist offen, wobei diese eine Vorkante aufweist die mindestens bis an eine Wandoberfläche hinreicht. Durch die so ausgebildete wasserundurchlässige Schale wird verhindert, dass Wasser an der Unterseiten, der Rückseite oder den Seitenbereichen des Einbauspülkastens austreten und in die Wand bzw. das Mauerwerk eintreten kann.The inventive use of a dimensionally stable and water-impermeable shell as a leakage protection device, which at least partially encloses the built-in cistern, effectively prevents accidental damage to the leakage protection device during assembly. While the film known in the prior art can easily be damaged by pointed tools or screws, this is not readily possible with a dimensionally stable shell made, for example, of plastic. The bowl is designed so that it at least partially surrounds the built-in cistern on the back. The same applies to side areas arranged within the masonry and an underside of the built-in cistern, which are likewise at least partially enclosed by the bowl. Only the front of the shell is open, which has a leading edge that extends at least to a wall surface. The water-impermeable bowl designed in this way prevents water from escaping from the underside, the rear or the side areas of the built-in cistern and from entering the wall or the masonry.

Vorteilhaft ist es dabei, wenn die Schale zusätzlich das zweite Leitungsmittel umschließt. Das zweite Leitungsmittel ist beispielsweise ein Wasserablaufrohr, welches den Einbauspülkasten mit einer Sanitäreinrichtung wie beispielsweise einer WC-Sitzkeramik verbindet.It is advantageous if the shell additionally encloses the second conduit. The second pipe means is, for example, a water drain pipe, which connects the built-in cistern to a sanitary facility, such as a toilet seat ceramic.

Besonders bewährt und kostengünstig ist es, wenn die Schale aus einem Polymerwerkstoff, wie beispielsweise einem Kunststoff aus der Gruppe der PP, PE, ABS, PS hergestellt ist. Hierzu bieten sich insbesondere tiefziehfähige Kunststoffe an, die in zahlreichen Farben und Ausführen verfügbar sind.It is particularly proven and cost-effective if the shell is made of a polymer material, such as a plastic from the group of PP, PE, ABS, PS. Thermoformable plastics are particularly suitable for this, and are available in numerous colors and designs.

Vorteilhafterweise beträgt eine Wandstärke der Schale zumindest im Bereich einer Wandoberfläche weniger als 60 mm, vorzugsweise weniger als 50 mm. Im Bereich der Wandoberfläche ist dazu eine Vorderkante vorgesehen, die zunächst eine Überlänge aufweist und über die Wandoberfläche hinausragt. In der fertigmontierten Einbauposition wird diese Vorderkante dann durch Zuschnitt auf die jeweilige Einbautiefe abgelängt und schließt danach bündig mit der Wandoberfläche ab. Der Zuschnitt wird durch die bevorzugten Wandstärken erleichtert, die gleichzeitig aber immer noch eine ausreichende Formstabilität der Schale sicherstellen.Advantageously, the wall thickness of the shell is less than 60 mm, preferably less than 50 mm, at least in the area of a wall surface. For this purpose, a front edge is provided in the area of the wall surface, which initially has an excess length and projects beyond the wall surface. In the fully assembled installation position, this front edge is then cut to size Installation depth cut to length and then flush with the wall surface. The cut is made easier by the preferred wall thicknesses, which at the same time still ensure adequate dimensional stability of the shell.

Bei einer ganz besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Schale wasserundurchlässige Durchtritte für Befestigungsmittel zur Befestigung des Einbauspülkastens aufweist. Hierdurch kann die Schale beispielsweise mit Schraubverbindungen an einem Wandausschnitt befestigt werden, um anschließend den Einbauspülkasten innerhalb der Schale anzuordnen. Führt man die Befestigungsmittel und die gegebenenfalls erforderlichen Durchtritte der Befestigungsmittel durch die Schale wasserundurchlässig aus, so ist die Funktionsfähigkeit der Leckageschutzeinrichtung bei gleichzeitiger Befestigungsmöglichkeit gewährleistet.In a very particularly preferred embodiment of the invention it is provided that the bowl has water-impermeable passages for fastening means for fastening the built-in cistern. As a result, the bowl can be fastened to a wall cutout, for example with screw connections, in order to subsequently arrange the built-in cistern within the bowl. If the fastening means and any necessary penetrations of the fastening means through the shell are made impermeable to water, the functionality of the leakage protection device is guaranteed with the possibility of fastening at the same time.

Eine andere bevorzugte Ausführungsform sieht vor, dass wenigstens der Einbauspülkasten und die Schale in einem Montagerahmen angeordnet sind. Ein solcher Montagerahmen kann beispielsweise aus Holz-, Metall- oder Kunststoffprofilen gefertigt sein und als mechanische Tragstruktur für den Einbauspülkasten und die Schale dienen. Der Einbauspülkasten kann hierbei mittels Schrauben, welche durch die Schale hindurch ragen am Montagerahmen befestigt sein. Der Montagerahmen selbst wiederum wird bei der Montage am Mauerwerk befestigt. Selbstverständlich sind auch hierbei die Durchtrittsstellen der Befestigungsmittel zur Verbindung von Einbauspülkasten, Schale und Montagerahmen wieder wasserundurchlässig ausgeführt.Another preferred embodiment provides that at least the built-in cistern and the bowl are arranged in a mounting frame. Such a mounting frame can for example be made of wood, metal or plastic profiles and serve as a mechanical support structure for the built-in cistern and the bowl. The built-in cistern can be attached to the mounting frame by means of screws that protrude through the bowl. The mounting frame itself is attached to the masonry during assembly. Of course, the passage points of the fasteners for connecting the built-in cistern, bowl and mounting frame are again made impermeable to water.

Vorzugsweise ist die Schale an einer Vorderseite offen ausgeführt. Im Rahmen der Erfindung ist hierdurch gewährleistet, dass im Falle einer Leckage Wasser an der Vorderseite aus der Schale austreten kann. Es ist dabei ferner möglich, die Vorderseite vollständig oder auch nur teilweise zu öffnen. Sieht man beispielsweise in einem unten liegenden Bereich der Schale eine teilweise Abdeckung der Vorderseite vor, kann so ein Reservoir vorgesehen werden, in dem sich eventuell austretendes Wasser sammelt. Ein Austreten des Wassers würde somit erst dann stattfinden, wenn eine Aufnahmekapazität des Reservoirs überschritten wird. Hierdurch kann ein Zeitgewinn erreicht werden, um eine mögliche Leckage zu erkennen, bevor Wasser aus der Schale austritt.The shell is preferably designed to be open on a front side. In the context of the invention, this ensures that water can escape from the front of the bowl in the event of a leak. It is also possible to open the front completely or only partially. If, for example, a partial covering of the front is provided in a region of the shell lying at the bottom, a reservoir can be provided in which any water that escapes collects. Only then would the water escape take place when a capacity of the reservoir is exceeded. This can save time in order to detect a possible leak before water emerges from the bowl.

Um nun zusätzlich zu gewährleisten, dass Wasser nicht in das Mauerwerk oder eine Wandkonstruktion eindringt, ist vorteilhafterweise vorgesehen, dass eine Einbautiefe der Schale so groß gewählt ist, dass diese im eingebauten Zustand mindestens bis an eine Wandöberfläche reicht. Hierbei kann die Einbautiefe der Schale ausreichend groß gewählt werden, so dass ein Überragen der Wandoberfläche in der Regel eintritt. Bei Bedarf kann dann die Einbautiefe der Schale im eingebauten Zustand exakt an die Kontur der Wandoberfläche angepasst werden. Dies ist beispielsweise durch ein einfaches Absägen des überstehenden Abschnitts der Schale zu erreichen.In order now to additionally ensure that water does not penetrate into the masonry or a wall construction, it is advantageously provided that the installation depth of the shell is selected to be so large that it extends at least to an upper wall surface in the installed state. Here, the installation depth of the shell can be chosen to be sufficiently large so that the wall surface usually projects above it. If necessary, the installation depth of the shell can then be adjusted exactly to the contour of the wall surface when installed. This can be achieved, for example, by simply sawing off the protruding section of the shell.

Besonders bewährt haben sich dabei Schalen, die eine Einbautiefe im Bereich von 100mm bis 350mm, vorzugsweise von 150mm bis 250mm aufweisen. So ausgebildete Schalen decken die allermeisten Anwendungsfälle ab.Shells that have an installation depth in the range from 100 mm to 350 mm, preferably from 150 mm to 250 mm, have proven particularly useful. Shells designed in this way cover the vast majority of applications.

Es ist zudem vorteilhaft, wenn die Schale an einer Unterseite wenigstens einen Sammelbereich für Leckagewasser aufweist, in dem sich austretendes Wasser zunächst sammelt. Hierzu kann es zunächst wahlweise in einem Reservoir gesammelt werden, um danach oder ohne vorherige Sammlung über eine Drainageleitung abgeleitet zu werden. Vorzugsweise ist zusätzlich eine Drainageleitung vorzusehen, welche die am Tiefpunkt gesammelte Leckageflüssigkeit ebenfalls zu einer Wandoberfläche ableitet. Im fertigmontierten Zustand kann somit eine Leckage des Einbauspülkastens unmittelbar durch das an der Wandoberfläche in den Raum austretende Leckagewasser erkannt werden.It is also advantageous if the shell has at least one collecting area for leakage water on an underside, in which escaping water initially collects. For this purpose, it can first be optionally collected in a reservoir, in order to then be discharged via a drainage line or without prior collection. In addition, a drainage line is preferably provided, which also drains the leakage liquid collected at the lowest point to a wall surface. In the fully assembled state, leakage from the built-in cistern can thus be recognized directly by the leakage water escaping into the room on the wall surface.

Die Erfindung sowie das technische Umfeld werden nachfolgend anhand der Figuren näher erläutert. Es ist darauf hinzuweisen, dass die Figuren besonders bevorzugte Ausführungsvarianten der Erfindung zeigen, auf die sie jedoch nicht beschränkt ist.The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the figures show particularly preferred embodiment variants of the invention, to which, however, it is not restricted.

In Figur 1 ist ein erfindungsgemäßer Einbauspülkasten 1 in einer Vorderansicht dargestellt. Der Einbauspülkasten 1 ist zusammen mit einer Sanitäreinrichtung 2 verbaut, die im vorliegenden Fall als hängende WC-Sitzkeramik ausgebildet ist. Eine Betätigungseinrichtung 3 ist ohne eine Betätigungsplatte dargestellt. Im unteren Bereich ist eine Mündung 4 eines Drainageschlauchs 5 dargestellt. Außerdem ist eine Vorderkante 6 einer Schale 7 dargestellt. Die Vorderkante 6 ist in einem nicht abgelängtemn Zustand dargestellt und ragt über eine Wandoberfläche 8 hinaus in Richtung einer Raummitte. Innerhalb der Schale 7 befindet sich noch eine Wandverkleidung 9, die nach erfolgter Montage in die Schale 7 eingesetzt und darin befestigt wird. Die Wandverkleidung 9 ist zur Wandoberfläche 8 planar ausgerichtet. Hierdurch können sowohl Wandverkleidung als auch Wandoberfläche nach dem Ablängen der Vorderkante 6 gemeinsam verkleidet werden, was beispielsweise durch das Verlegen von nicht dargestellten Fliesen erfolgen kann.In Figure 1 A built-in cistern 1 according to the invention is shown in a front view. The built-in cistern 1 is installed together with a sanitary device 2, which in the present case is designed as a hanging toilet seat ceramic. An actuator 3 is shown without an actuator plate. A mouth 4 of a drainage hose 5 is shown in the lower area. A front edge 6 of a shell 7 is also shown. The front edge 6 is shown in a non-cut state and protrudes beyond a wall surface 8 in the direction of a center of the room. Inside the shell 7 there is also a wall covering 9 which, after assembly, is inserted into the shell 7 and fastened therein. The wall covering 9 is aligned planar to the wall surface 8. As a result, both the wall cladding and the wall surface can be clad together after the front edge 6 has been cut to length, which can be done, for example, by laying tiles, not shown.

In Figur 2 ist der Einbauspülkasten nach Figur 1 in einer vertikalen Schnittansicht dargestellt. Der Einbauspülkasten 1 sitzt innerhalb der Schale 7 und wird von dieser sowohl an der Rückseite als auch der Oberseite, der Unterseite sowie der rechten und linken Seite vollständig umschlossen. Damit ist zusammengefasst der Einbauspülkasten 1 sowohl seitlich als auch an seiner Rückseite vollständig von der Schale 7 umschlossen. Die Rückseite 10 bildet dabei die Seite, welche der Wand beziehungsweise dem Mauerwerk zugewandt ist. Über ein erstes Leitungsmittel 11, das an einen Wasserzulaufanschluss 12 angeschlossen ist, wird der Einbauspülkasten 1 mit Wasser versorgt. Die Ableitung des Wassers erfolgt über ein zweites Leitungsmittel 13, welches über einen Wasserablaufanschluss 14 mit dem Einbauspülkasten verbunden ist und diesen mit der Sanitäreinrichtung 2 verbindet. Die Sanitäreinrichtung 2 ist ihrerseits an einem Montagerahmen 15 befestigt, der auch den Einbauspülkasten 1 und die Schale 7 aufnimmt.In Figure 2 is the built-in cistern after Figure 1 shown in a vertical sectional view. The built-in cistern 1 sits within the bowl 7 and is completely enclosed by this on the back as well as the top, the bottom and the right and left side. In summary, the built-in cistern 1 is completely enclosed by the bowl 7 both on the side and on its rear. The back 10 forms the side which faces the wall or the masonry. The built-in cistern 1 is supplied with water via a first line means 11, which is connected to a water inlet connection 12. The water is drained off via a second line means 13, which is connected to the built-in cistern via a water drain connection 14 and connects this to the sanitary device 2. The sanitary device 2 is in turn attached to a mounting frame 15 which also houses the built-in cistern 1 and the bowl 7.

In Figur 3 ist die Einzelheit A nach Figur 2 noch einmal vergrößert dargestellt. Das erste Leitungsmittel 11 leitet über einen verdeckt dargestellten Seitenbereich 16 Wasser über den Wasserzulaufanschluss 12 in den Einbauspülkasten 1. Gut erkennbar ist hier, dass die Schale 7 den Einbauspülkasten 1 sowohl an der Rückseite 10 als auch am Seitenbereich 16 dicht umschließt. Der Montagerahmen 15 ist über eine Befestigungseinrichtung 17 fest mit dem Gebäude verbunden und trägt sowohl die Wandverkleidung 9, die Schale 7 sowie den Einbauspülkasten 1 als auch die Sanitäreinrichtung 2.In Figure 3 is the detail A after Figure 2 shown enlarged again. The first conduit 11 conducts water through a concealed side region 16 into the built-in cistern 1 via the water inlet connection 12. It can be clearly seen here that the bowl 7 tightly encloses the built-in cistern 1 both on the rear side 10 and on the side region 16. The mounting frame 15 is firmly connected to the building via a fastening device 17 and carries both the wall cladding 9, the bowl 7 and the built-in cistern 1 and the sanitary device 2.

In Figur 4 ist die Einzelheit B nach Figur 2 dargestellt. In dem unteren Abschnitt des Einbauspülkastens 1 ist wiederum die Schale 7 erkennbar mit der Vorderkante 6. Innerhalb der Schale ist die Wandverkleidung 9 angeordnet. Im Bereich unterhalb des zweiten Leitungsmittels 13 ist gut erkennbar ein Sammelbereich bzw. Reservoir 18 angeordnet zur Ansammlung von Leckagewasser. An den Sammelbereich 18 ist eine Drainageleitung 19 angeschlossen. Die Drainageleitung 19 ist nur teilweise dargestellt und wird unter Bezugnahme auf Figur 6 noch näher erläutert. Der Sammelbereich 18 ist an einer Unterseite 20 des Einbauspülkastens angeordnet, um das Sammeln von Leckagewasser zu begünstigen.In Figure 4 is the detail B after Figure 2 shown. In the lower section of the built-in cistern 1, the bowl 7 can again be seen with the front edge 6. The wall cladding 9 is arranged within the bowl. A collection area or reservoir 18 for collecting leakage water is clearly visible in the area below the second line means 13. A drainage line 19 is connected to the collecting area 18. The drainage line 19 is only partially shown and is described with reference to FIG Figure 6 explained in more detail. The Collection area 18 is arranged on an underside 20 of the built-in cistern in order to promote the collection of leakage water.

Figur 5 zeigt den erfindungsgemäßen Einbauspülkasten 1 in einer Seitenansicht. Der Einbauspülkasten 1 ist von der Schale 7 vollständig umschlossen, wobei die Drainageleitung 19 im unteren Bereich 18 gut erkennbar ist. Der Montagerahmen 15 weist Befestigungsmittel 21 auf, durch die der Einbauspülkasten 1 und die Schale 7 mit dem Montagerahmen 15 verbunden sind. Im vorliegenden Fall handelt es sich dabei um Schrauben, die durch die Schale 7 hindurch treten. Die Durchtrittsstellen sind jeweils wasserdicht ausgeführt, so dass kein Leckagewasser durch die Durchtrittsstellen aus der Schale 7 austreten kann. Figure 5 shows the built-in cistern 1 according to the invention in a side view. The built-in cistern 1 is completely enclosed by the bowl 7, the drain line 19 being clearly visible in the lower region 18. The mounting frame 15 has fastening means 21 through which the built-in cistern 1 and the bowl 7 are connected to the mounting frame 15. In the present case, these are screws that pass through the shell 7. The passage points are each made watertight so that no leakage water can escape from the shell 7 through the passage points.

In Figur 6 ist eine Rückansicht des Montagerahmens 15 mit dem Einbauspülkasten 1 und der Schale 7 dargestellt. An der Unterseite 18 ist die Drainageleitung 19 gut erkennbar, die von der Unterseite 20 mit dem Sammelbereich 18 hin zur Mündung 4 des Drainageschlauchs 6 führt.In Figure 6 a rear view of the mounting frame 15 with the built-in cistern 1 and the bowl 7 is shown. On the underside 18, the drainage line 19 is clearly visible, which leads from the underside 20 with the collecting area 18 to the mouth 4 of the drainage hose 6.

In Figur 7 ist der Einbauspülkasten 1 nochmals in einer perspektivischen Darstellung gezeigt mit der Betätigungseinrichtung 3, der Wandoberfläche 8, wobei die Wandverkleidung 9 hierbei entnommen ist. Der Einbauspülkasten 1 ist vollständig von der Schale 7 umschlossen, deren Vorderkante 6 erkennbar nicht gekürzt ist und weist noch die volle Einbautiefe auf. Dies erfolgt erst im fertig montierten Zustand, bevor die endgültige Oberflächenverkleidung aufgebracht wird. Im rechten unteren Bereich ist noch der Drainageschlauch 5 erkennbar mit der Mündung 4. Gut erkennbar ist in dieser Darstellung, dass gegebenenfalls an der Unterseite 20 angesammeltes Leckagewasser ausschließlich in Richtung des Innenraums abgeleitet werden kann und somit Wasserschäden weitestgehend vermieden werden.In Figure 7 the built-in cistern 1 is again shown in a perspective view with the actuating device 3, the wall surface 8, the wall covering 9 being removed in this case. The built-in cistern 1 is completely enclosed by the bowl 7, the front edge 6 of which is clearly not shortened and still has the full installation depth. This takes place only in the fully assembled state before the final surface cladding is applied. In the lower right area, the drainage hose 5 with the mouth 4 can still be seen. It can be clearly seen in this illustration that any leakage water that has accumulated on the underside 20 can only be drained off in the direction of the interior and water damage can thus be largely avoided.
