Description

Die Erfindung betrifft einen Unterputzspülkasten nach dem Oberbegriff des Anspruchs 1.The invention relates to a concealed cistern according to the preamble of claim 1.

Unterputzspülkästen der genannten Art sind zum Spülen von Toiletten oder Urinalen gut bekannt. Sie werden vor einer Gebäudewand an einem Gestell, oder in einer Nische einer Gebäudewand montiert. Nach dem Verputzen sind solche Spülkästen mit Ausnahme einer Betätigungsvorrichtung, beispielsweise einer Betätigungsplatte nicht mehr sichtbar. An solchen Spülkästen und an der angrenzenden Gebäudewand kann Schwitzwasser entstehen, wenn die Wandtemperatur des Spülkastens so weit absinkt, dass die in der Raumluft enthaltene Feuchtigkeit kondensiert. Wasser kondensiert am Spülkasten bzw. an der angrenzenden Gebäudewand, wenn die Wandtemperatur den Taupunkt der Luft unterschreitet. Ob es zu einer Kondensation kommt, hängt einerseits von der Wandtemperatur und andererseits von der Luftfeuchtigkeit ab. Die Luftfeuchtigkeit kann als gegeben angesehen werden. Deshalb muss zur Verringerung einer Schwitzwasserbildung vermieden werden, dass die Wandtemperatur des Spülkastens unterhalb des Taupunktes absinkt.Concealed cisterns of the type mentioned are well known for flushing toilets or urinals. They are mounted in front of a building wall on a rack, or in a niche of a building wall. After plastering such cisterns with the exception of an actuator, such as an actuator plate are no longer visible. In such cisterns and on the adjacent building wall condensation may occur when the wall temperature of the cistern drops so low that condenses the moisture contained in the room air. Water condenses on the cistern or on the adjacent building wall when the wall temperature falls below the dew point of the air. Whether condensation occurs depends on the one hand on the wall temperature and on the other hand on the humidity. The humidity can be considered as given. Therefore, to reduce the formation of condensation, it must be avoided that the wall temperature of the cistern falls below the dew point.

Insbesondere bei engen Raumverhältnissen besteht seit langem der Bedarf nach einer raumsparenden Montage von Unterputzspülkästen.Especially in tight spaces has long been the need for a space-saving installation of concealed cisterns.

Der bisher übliche Einbau von Isolationsschichten aus Polystyrol in den Kastenkörper wirkt dem entgegen.The usual installation of insulating layers of polystyrene in the box body counteracts this.

Die EP-A-1 172 490 offenbart einen Wandeinbau-Spülkasten, der einen Kastenkörper besitzt, bei dem auf der Rückwand als auch auf der Vorderwand im Wasserbereich eine aussenseitige und versenkt angeordnete Isolationsschicht zur Schwitzwasserisolation aufgebracht ist.The EP-A-1 172 490 discloses a wall-mounted cistern, which has a box body, in which on the rear wall and on the front wall in the water area an outer side and recessed insulation layer is arranged for condensation insulation.

Der Erfindung liegt die Aufgabe zugrunde, einen Unterputzspülkasten zu schaffen, der einerseits wirksam gegen Schwitzwasser isoliert ist und andererseits raumsparend montiert werden kann.The invention has for its object to provide a concealed cistern, on the one hand effectively insulated against condensation and on the other hand can be mounted to save space.

Die Aufgabe ist bei einem gattungsgemässen Unterputzspülkasten gemäss Anspruch 1 gelöst.The object is achieved in a generic flush-mounted cistern according to claim 1.

Der erfindungsgemässe Unterputzspülkasten kann ähnlich einem Baustein in eine Gebäudewand eingesetzt werden. Der Unterputzspülkasten erfordert deshalb keinen zusätzlichen Raum und kann in einfacher Weise mit einem Verputz überdeckt werden, wobei selbstverständlich die Revisionsöffnung für den Anbau einer Betätigungsvorrichtung und der Spülwasserauslass frei bleiben. Durch die versenkte Anordnung der Isolationsschicht ist eine sehr geringe Tiefe des Unterputzspülkastens von 8 cm oder kleiner möglich. Trotzdem ist eine Dicke der Isolationsschicht möglich, die eine wirksame Schwitzwasserisolation auch unter Verwendung von kostengünstigem Material ermöglicht.The inventive concealed cistern can be used similar to a block in a building wall. The concealed cistern therefore requires no additional space and can be covered in a simple manner with a plaster, of course, the inspection opening for the cultivation of an actuator and the Spülwasserauslass remain free. Due to the recessed arrangement of the insulation layer is a very small depth of the concealed cistern of 8 cm or smaller possible. Nevertheless, a thickness of the insulating layer is possible, which allows an effective condensation water insulation also using inexpensive material.

Versuche haben gezeigt, dass ein Wärmedurchgangskoeffizient der Isolation im k-Wertbereich von 7-10 (W/m2K) optimal ist. Zusammen mit dem Spülkasten ergibt sich ein k-Wertbereich von 4,5 bis 6 (W/m2K).Experiments have shown that a heat transfer coefficient of the insulation in the k-value range of 7-10 (W / m2K) is optimal. Together with the cistern results in a k-value range of 4.5 to 6 (W / m2K).

Nach der Erfindung ist vorgesehen, dass das Spülrohr und die auf diesem aufgebrachte Isolationsschicht im zusammengesetzten Zustand ablängbar ist. Dadurch ist eine einfache Anpassung an unterschiedliche Anschlusshöhen möglich.According to the invention, it is provided that the flushing pipe and the insulation layer applied thereto can be cut to length in the assembled state. This allows easy adaptation to different connection heights.

Eine besonders kostengünstige Ausführung bei optimaler Schwitzwasserisolation ergibt sich nach einer Weiterbildung der Erfindung dann, wenn die Dicke der Isolationsschicht etwa 4 mm beträgt und aus EPS hergestellt ist.A particularly cost-effective design with optimal condensation insulation is obtained according to a development of the invention, when the thickness of the insulating layer is about 4 mm and is made of EPS.

Nach der Erfindung ist zudem das Spülrohr aussenseitig mit einer Isolationsschicht umgeben. Die Tiefe dieser Isolationsschicht kann ebenfalls etwa gleich oder kleiner als 8 cm sein.According to the invention, the flushing pipe is also surrounded on the outside with an insulating layer. The depth of this insulating layer may also be about equal to or less than 8 cm.

Eine besonders einfache Installation ergibt sich dann, wenn das Spülrohr an einem Spülkastenstutzen aufsteckbar ist.A particularly simple installation results when the flushing pipe can be attached to a Spülkastenstutzen.

Die Installation wird weiter vereinfacht, wenn gemäss der Erfindung vorgesehen ist, dass der Spülkastenkörper am Boden einen Anschlag für die Isolationsschicht des Spülrohrs aufweist. Alternativ kann die Isolationsschicht des Spülkastenkörpers einen Anschlag für die Isolationsschicht des Spülrohrs aufweisen. Vorzugsweise wird dieser Anschlag durch einen ringförmigen Ansatz der Isolationsschicht des Kastenkörpers gebildet.The installation is further simplified if it is provided according to the invention that the Spülkastenkörper has a stop for the insulating layer of the flushing pipe at the bottom. Alternatively, the insulating layer of the Spülkastenkörpers have a stop for the insulating layer of the flushing pipe. Preferably, this stop is formed by an annular projection of the insulating layer of the box body.

Eine genaue Anpassung an unterschiedliche Installationshöhen ist gemäss der Erfindung einfach, wenn das Spülrohr in seiner Isolationsschicht nach der Installation höhenverstellbar ist. Die Verstellung erfolgt vorzugsweise durch Verschieben des Spülrohrs in der Isolationsschicht.Accurate adaptation to different installation heights is simple according to the invention if the flushing pipe in its insulating layer is height-adjustable after installation. The adjustment is preferably carried out by moving the flushing pipe in the insulation layer.

Weitere vorteilhaft Merkmale ergeben sich aus dem abhängigen Patentanspruch, der nachfolgenden Beschreibung sowie der Zeichnung.Other advantageous features emerge from the dependent claim, the following description and the drawings.

Der in Figur 1 gezeigte Unterputzspülkasten 1 weist einen Kastenkörper 2 auf, der aus einem geeigneten Kunststoff, beispielsweise durch Blasformen hergestellt ist. Im oberen Bereich einer Vorderwand 2a ist mittig eine rechteckige Öffnung 6 angebracht, welche zum Anbau einer Betätigungsvorrichtung, beispielsweise einer Betätigungsplatte vorgesehen ist. Durch diese Revisionsöffnung 6 greift ein hier nicht gezeigter Betätigungshebel in den Innenraum 29 ein, mit dem ein Verschlusskörper 15 eines Ablaufventils 14 zur Spülauslösung anhebbar ist. Der Verschlusskörper 15 weist gemäss Figur 2 einen gummielastischen Ventilkörper 18 auf, der bei geschlossenem Ablaufventil auf einem kreiszylindrischen Körper 17 aufliegt, der mit einem von unten in den Kastenkörper 2 eingesetztem Anschlussstutzen 9 verbunden ist. Der Körper 17 bildet einen Ventilsitz für den Verschlusskörper 15. Zwischen dem Körper 17 und dem Anschlussstutzen 9 ist ein Dichtungsring 16 eingesetzt, welcher den Körper 17 gegenüber dem Anschlussstutzen 9 abdichtet. Der separat hergestellte Anschlussstutzen 9 ermöglicht einen Einbau der Ablaufgarnitur 14 von unten. Dies ist bei einem schmalen Spülkasten besonders vorteilhaft. Nach dem Aufsetzen des Anschlussstutzens 9 auf den Kastenkörper 2 wird ein nach oben gerichteter umlaufender Rand 9a mit dem Kastenkörper 2 verschweisst. Der Anschlussstutzen 9 ist dicht mit dem Kastenkörper 2 verbunden und bildet eine untere Auslauföffnung 30, durch welche bei einer Spülung Spülwasser W in einen Auslauf 4 gelangt.The in FIG. 1 shown flushing cistern 1 has a box body 2, which is made of a suitable plastic, for example by blow molding. In the upper area of a front wall 2a, a rectangular opening 6 is centrally mounted, which is provided for mounting an actuating device, for example an actuating plate. Through this access opening 6, an actuating lever, not shown here engages in the interior 29, with which a closure body 15 of a drain valve 14 for flushing release can be raised. The closure body 15 has according to FIG. 2 a rubber-elastic valve body 18 which rests on a circular cylindrical body 17 with the drain valve closed, which is connected to an inserted from below into the box body 2 connecting piece 9. The body 17 forms a valve seat for the closure body 15. Between the body 17 and the connecting piece 9, a sealing ring 16 is inserted, which seals the body 17 relative to the connecting piece 9. The separately produced connection piece 9 allows installation of the drain fitting 14 from below. This is particularly advantageous in a narrow cistern. After placing the connecting piece 9 on the box body 2, an upwardly directed peripheral edge 9a is welded to the box body 2. The connecting piece 9 is tightly connected to the box body 2 and forms a lower outlet opening 30 through which rinse water W enters a spout 4 at a rinse.

Zur Schwitzwasserisolation ist der Kastenkörper 2 im Wasserbereich aussenseitig mit einer Isolationsschicht 3 verbunden. Diese Isolationsschicht 3 besteht beispielsweise aus EPS (Expandiertes Polystyrol) und besitzt eine Dicke von vorzugsweise etwa 4 mm. Die Isolationsschicht 3 erstreckt sich über eine Vorderseite 3a, eine Rückseite 3b sowie über die hier nicht gezeigten Schmalseiten. Zudem überdeckt die Isolationsschicht 3 den Bodenbereich des Kastenkörpers 2 und besitzt mittig einen zylindrischen Ansatz 3c, welcher einen Teilbereich des Anschlussstutzens 9 umgreift, wie insbesondere die Figur 2 deutlich zeigt. Die Isolationsschicht 3 ist bezüglich eines hinteren Wandbereichs 3d und eines vorderen Wandbereichs 3e versetzt angeordnet. Die Rückseite 8 der Isolation 3b ist damit bündig mit der Aussenseite 26 des Bereichs 3d. Auch auf den hier nicht gezeigten Schmalseiten des Kastenkörpers 2 ist die Isolationsschicht 3 vorzugsweise bündig nach innen versetzt. Entsprechend ist die Aussenseite 7 des Isolationsbereichs 3a bündig mit der Aussenseite des Bereichs 3e. Dadurch kann der Unterputzspülkasten 1 besonders kompakt und mit einer vergleichsweise geringen Tiefe A hergestellt werden. Diese Tiefe A beträgt etwa 8 cm oder weniger. Durch diese geringe Bautiefe ist es möglich, den Unterputzspülkasten 1 ähnlich einem Baustein in eine Gebäudewand 19 einzubauen, wie dies in den Figuren 3 bis 5 schematisch dargestellt ist. Die in Figur 3 gezeigte Gebäudewand 19 ist aus einzelnen hier nicht gezeigten Bausteinen mit einer Bausteinbreite B von etwa 8 cm hergestellt. Da die Tiefe A des Unterputzspülkastens 1 ebenfalls etwa 8 cm oder weniger beträgt, kann der Unterputzspülkasten 1 in einen Durchbruch 27 eingebaut und beim Verputzen abgedeckt werden. Lediglich die Revisionsöffnung 6 und eine vorstehende Mündung 13 des Spülrohrs 10 sind hierbei frei bleibend. Die Befestigung des Unterputzspülkastens 1 erfolgt mit einer Verstrebung 21 oder 22, wie dies in den Figuren 4 und 5 gezeigt ist.For condensation insulation, the box body 2 in the water area is connected on the outside to an insulation layer 3. This insulating layer 3 consists for example of EPS (expanded polystyrene) and has a thickness of preferably about 4 mm. The insulating layer 3 extends over a front side 3a, a back side 3b and over the narrow sides not shown here. In addition, the insulating layer 3 covers the bottom portion of the box body 2 and has a cylindrical center 3c, which surrounds a portion of the connecting piece 9, in particular the center FIG. 2 clearly shows. The insulating layer 3 is staggered with respect to a rear wall portion 3d and a front wall portion 3e. The back 8 of the insulation 3b is thus flush with the outside 26 of the area 3d. Also on the narrow sides of the box body 2, not shown here, the insulating layer 3 is preferably offset flush inside. Accordingly, the outside 7 of the insulation area 3a is flush with the outside of the area 3e. As a result, the concealed cistern 1 can be made particularly compact and with a comparatively small depth A. This depth A is about 8 cm or less. Due to this small construction depth, it is possible to install the concealed cistern 1 similar to a building block in a building wall 19, as shown in the FIGS. 3 to 5 is shown schematically. In the FIG. 3 shown building wall 19 is made of individual components not shown here with a module width B of about 8 cm. Since the depth A of the concealed cistern 1 is also about 8 cm or less, the concealed cistern 1 can be installed in an opening 27 and covered during plastering. Only the inspection opening 6 and a protruding mouth 13 of the flushing pipe 10 are hereby free. The attachment of the concealed cistern 1 is carried out with a strut 21 or 22, as shown in the FIGS. 4 and 5 is shown.

Das Spülrohr 10 des Auslaufs 4 ist gemäss Figur 2 auf den Anschlussstutzen 9 aufgesetzt und gegenüber diesem mit einem Dichtungsring 28 abgedichtet. Auf dem Stutzen 9 ist das Spülrohr 10 in Längsrichtung verschiebbar. Das Spülrohr 10 ist von einer Isolation 11 umgeben, die beispielsweise ebenfalls aus EPS hergestellt ist. In dieser Isolation 11 ist das Spülrohr 10 begrenzt höhenverschiebbar. Der Bereich der Verschiebbarkeit ergibt sich durch eine untere Öffnung 12, durch welche das Spülrohr 10 horizontal mit einer Mündung 13 vorragt. Die Öffnung 12 ist wie ersichtlich grösser als der Durchmesser der Mündung 13. Mittels eines Klotzes 5 aus EPS kann die Mündung 13 als Bauschutzmassnahme abgedeckt werden. Dieser Klotz 5 ragt mit einem oberen Ansatz 5a in die Öffnung 12. Nach dem Entfernen des Klotzes 5 kann das Spülrohr 10 nach oben in der Isolation 11 bis zu einem oberen Anschlag verschoben werden. Die Isolation 11 liegt an einem oberen Rand 11a am Ansatz 3c an. Das Spülrohr 10 wird beim genannten Verschieben nach oben in diesen Ansatz 3c hineingeschoben. Die Isolation des Spülrohrs 10 bleibt hierbei erhalten. Vor dem Aufsetzen des Spülrohrs 10 kann dieses zusammen mit der Isolation 11 am oberen Rand 11a abgelängt werden. Ein zu langes Spülrohr 10 kann somit zusammen mit der Isolation 11 verkürzt werden, falls dies aufgrund der Einbausituation erforderlich sein sollte. Durch ein Verschieben des Spülrohrs 10 kann dann die genaue Position der Mündung 13 fein eingestellt werden.The flushing pipe 10 of the outlet 4 is according to FIG. 2 placed on the connecting piece 9 and sealed with respect to this with a sealing ring 28. On the nozzle 9, the purge pipe 10 is displaceable in the longitudinal direction. The flushing pipe 10 is surrounded by an insulation 11, which is also made of EPS, for example. In this isolation 11, the flushing pipe 10 is limited in height. The range of the displaceability results from a lower opening 12, through which the flushing pipe 10 projects horizontally with an orifice 13. As can be seen, the opening 12 is larger than the diameter of the mouth 13. By means of a block 5 of EPS, the mouth 13 can be covered as a construction protection measure. This block 5 protrudes with an upper projection 5a in the opening 12. After removal of the pad 5, the flushing pipe 10 can be moved upwards in the insulation 11 to an upper stop. The insulation 11 abuts an upper edge 11a on the neck 3c. The flushing pipe 10 is pushed into said approach 3c during said shifting upwards. The isolation of the flushing pipe 10 is retained in this case. Before placing the flushing pipe 10, this can be cut to length along with the insulation 11 at the upper edge 11a. A too long flush pipe 10 can thus be shortened together with the insulation 11, if this should be necessary due to the installation situation. By moving the flushing pipe 10, the exact position of the mouth 13 can then be finely adjusted.

Die Figur 7 zeigt einen Anschlussstutzen 9' gemäss einer Variante. Bei diesem Anschlussstutzen 9' ist ein nach unten ragender rohrförmiger Teil 9b' angeformt, der wie ersichtlich als Anschlag für die Isolation 11 dient. Auch in diesem Fall kann das Spülrohr 10 in der Isolation 11 nach oben verschoben werden. Die Mündung 13 kann dadurch genau auf die Höhe von Rohrstücken 13 und 24 zu einer Abdeckkappe 25 der Spülwasserleitung angepasst werden.The FIG. 7 shows a connecting piece 9 'according to a variant. In this connection piece 9 'a downwardly projecting tubular part 9b' is formed, which serves as a stop for the insulation 11 as can be seen. Also in this case, the flushing pipe 10 can be moved in the insulation 11 upwards. The mouth 13 can be adjusted exactly to the height of pipe sections 13 and 24 to a cap 25 of the flushing water pipe.
