Abstract

The connector part has an end-sided connection face for a water tap. A water outlet bore extends from the connection face, and contains a ventilation unit (2) in the form of a multiport valve (20). The outflowing water impacts axially on the valve. The valve has two ring-shaped seats (201,202) and a valve closure member (21) movable between the seats. Water outlet is radial between the valve seats. The end section of the bore behind the downstream valve seat is connected to the atmosphere. The bore is a horizontal dead end bore, and its end cuts across a transverse bore. This forms the connection to the atmosphere. The bore also contains a water drip discharge channel.

Description

Die Erfindung betrifft ein Unterputz-Anschlußstück für wenigstens ein Wasserventil, insbesondere Wassermischventil und/oder Wasserverteilventil, mit wenigstens einer Zuflußöffnung und wenigstens einer Abflußöffnung, wobei stirnseitig eine Anschlußfläche für ein Wasserventil ausgebildet ist.The invention relates to a flush-mounted connector for at least one water valve, in particular water mixing valve and / or water distribution valve, with at least one Inflow opening and at least one outflow opening, with a connection surface for a water valve is trained.

Ein derartiges Unterputz-Anschlußstück ist durch offenkundige Vorbenutzung bekanntgeworden. Hierbei ist an der Anschlußfläche eine Mischventilkartusche mit Spannschrauben gedichtet befestigt, wobei die Anschlußfläche parallel zur Gebäudewandoberfläche angeordnet ist. In etwa waagerechter Ebene ist auf jeder Seite jeweils ein Anschluß für das zufließende Kalt- und Warmwasser und etwa vertikal übereinanderliegend je ein Anschluß für die Abgabe von Mischwasser vorgesehen. Zwischen den beiden Anschlüssen für die Abgabe von Mischwasser ist dem Unterputz-Anschlußstück ein Wasserverteilventil in einer separaten Bohrung angeordnet, mit dem das in der Mischventilkartusche erzeugte Mischwasser wahlweise dem oberen oder dem unteren Anschluß zugeführt werden kann, wobei das Wasserverteilventil so ausgebildet ist, daß es nach dem Absperren des ausfließenden Mischwassers in eine bevorzugte Auslaufstellung selbsttätig zurückkehrt. Wenn bei diesen Unterputz-Anschlußstücken eine Handbrause mit einem Schlauch und/oder der Mischwasserauslauf in einer Badewanne angeordnet ist, ist es erforderlich, separate Rohrbelüftereinrichtungen vorzusehen, die verhindern, daß bei einem Unterdruck im Versorgungsleitungsnetz Schmutzwasser in das Leitungsnetz zurückgesaugt wird. Die Installation der einzelnen Rohrbelüftungseinrichtungen in den Auslaufleitungen ist relativ aufwendig.Such a flush-mounted connector is by obvious Prior use became known. Here is on a mixing valve cartridge with clamping screws sealed attached, the pad is arranged parallel to the building wall surface. In approximately horizontal level is one on each side Connection for the incoming cold and warm water and approximately vertically one above the other a connection for the supply of mixed water is provided. Between both connections for the discharge of mixed water is the flush-mounted connector a water distribution valve in a separate hole with which the in the Mixing valve cartridge optionally produces mixed water upper or lower connection can be fed wherein the water distribution valve is designed so that it after shutting off the outflowing mixed water a preferred outlet position returns automatically. If with these flush-mounted fittings Hand shower with a hose and / or the mixed water outlet is placed in a bathtub, it is necessary to provide separate pipe aerators, which prevent a negative pressure in the supply network Dirty water in the mains is sucked back. The installation of each Pipe ventilation devices in the outlet pipes relatively complex.

Der Erfindung liegt die Aufgabe zugrunde, bei dem im Oberbegriff des Anspruchs 1 angegebenen Unterputz-Anschlußstück die Installation der Rohrbelüfter zu vereinfachen, und die Rohrbelüfter kostengünstiger auszubilden.The invention is based, in which Preamble of claim 1 specified flush-mounted connector to simplify the installation of the pipe aerator, and to train the pipe aerators more cost-effectively.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß von der Anschlußfläche ausgehend eine Bohrung für den Abfluß ausgebildet ist, in der eine Belüftungseinrichtung in Form eines Mehrwegeventils angeordnet ist, welches axial vom ausfließenden Wasser angeströmt ist, wobei das Ventil mit zwei ringförmigen Ventilsitzen versehen ist, zwischen denen ein Ventilverschlußglied beweglich angeordnet ist, und der Abfluß radial zwischen den beiden Ventilsitzen in der Wandung erfolgt, während der Endbereich der Bohrung hinter dem stromabwärts gelegenen Ventilsitz mit der Atmosphäre verbunden ist.
Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 10 angegeben.This object is achieved in that, starting from the connection surface, a bore is formed for the drain, in which a ventilation device is arranged in the form of a multi-way valve, which is axially flowed by the outflowing water, the valve being provided with two annular valve seats between which a valve closure member is movably arranged, and the discharge takes place radially between the two valve seats in the wall, while the end region of the bore is connected to the atmosphere behind the downstream valve seat.
Further refinements of the invention are specified in claims 2 to 10.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß eine besondere Installation von Rohrbelüftern nicht mehr erforderlich ist. Darüber hinaus ist ein besonderes Rohrbelüftergehäuse für die einzelnen Rohrbelüfter nicht mehr erforderlich, da die Belüftungseinrichtung in dem Unterputz-Anschlußstück integriert ist.
Vorteilhaft kann die Belüftungsvorrichtung als Baueinheit ausgebildet werden, die als Einheit in die Bohrung des Unterputz-Anschlußstücks einsetzbar ist. Hierbei kann zweckmäßig das Mehrwegeventil mit einem weiteren zweiten Ventil hintereinander angeordnet werden. Die Belüftungseinrichtung kann vorteilhaft in einer waagerecht angeordneten Bohrung in dem Unterputz-Anschlußstück angeordnet werden, wobei die Verschlußglieder beider Ventile zweckmäßig als Kugeln ausgebildet sind.
Selbstverständlich kann die Belüftungseinrichtung auch in einer anderen, beliebigen Einbaulage angeordnet werden. Wenn die Belüftungseinrichtung jedoch eine mehr lotrechte Einbaulage einnimmt, dann sollten die Ventilverschlußglieder aus einem im Wasser schwimmbaren Werkstoff hergestellt und/oder wenigstens das stromabwärts gelegene Ventilverschlußglied mit einer Feder in Schließrichtung gedrückt sein.The advantages which can be achieved with the invention consist in particular in the fact that a special installation of tube aerators is no longer necessary. In addition, a special pipe aerator housing is no longer required for the individual pipe aerators, since the ventilation device is integrated in the flush-mounted connector.
The ventilation device can advantageously be designed as a structural unit which can be used as a unit in the bore of the flush-mounted connecting piece. In this case, the multi-way valve can advantageously be arranged one behind the other with a further second valve. The ventilation device can advantageously be arranged in a horizontally arranged bore in the flush-mounted connection piece, the closure members of both valves advantageously being designed as balls.
Of course, the ventilation device can also be arranged in any other desired installation position. However, if the ventilation device assumes a more vertical installation position, then the valve closure members should be made of a material that is floatable in the water and / or at least the valve closure member located downstream should be pressed in the closing direction with a spring.

In weiterer Ausgestaltung der Erfindung kann zur sicheren Halterung der Belüftungseinrichtung in der Stecklage in der Bohrung ein Sprengring vorgesehen oder an der Anschlußfläche des Unterputz-Anschlußstücks eine Platte mit Schrauben und Rundschnurringen gedichtet befestigt werden. An der Platte können außerdem Gewindebohrungen vorgesehen werden, in die Spannschrauben für die Befestigung einer Mischventilkartusche einschraubbar sind, so daß eine sichere und dichte Befestigung der Mischventilkartusche gewährleistet ist. Nach der Demontage der Kartusche ist somit die Belüftungseinrichtung für Wartungszwecke einfach zugänglich. Durch die Anordnung der Belüftungseinrichtung stromaufwärts vor einem Wasserverteilventil wird außerdem sichergestellt, daß beide Mischwasseranschlüsse von einer Belüftungseinrichtung abgesichert werden.
Schließlich kann vorteilhaft in dem Unterputz-Anschlußstück ein Tropfwasserabflußkanal ausgebildet werden, der in eine Tropfwasserleitung mündet. Eine seitlich aus dem Unterputz-Anschlußstück herausgeführte Querbohrung ist hierbei jeweils von der Bohrung zur Aufnahme der Belüftungseinrichtung steigend angeordnet, so daß, wenn beim Betrieb der Armatur Leckagen an der Belüftungseinrichtung auftreten, diese zwangsläufig von dem Tropfwasser-Abflußkanal aufgenommen werden. Hiernach gelangt das Leckwasser über die Tropfwasserleitung aus der Gebäudewand heraus zur Rückseite der Abdeckrosette. In a further embodiment of the invention, a snap ring can be provided for securely holding the ventilation device in the plug-in position in the bore or a plate can be fastened in a sealed manner to the connection surface of the flush-mounted connection piece with screws and round cord rings. In addition, threaded holes can be provided on the plate, into which clamping screws can be screwed for fastening a mixing valve cartridge, so that a secure and tight attachment of the mixing valve cartridge is ensured. After the cartridge has been dismantled, the ventilation device is easily accessible for maintenance purposes. The arrangement of the ventilation device upstream in front of a water distribution valve also ensures that both mixed water connections are secured by one ventilation device.
Finally, a drip water drain channel can advantageously be formed in the flush-mounted connector, which opens into a drip water pipe. A transverse bore led out laterally from the flush-mounted connecting piece is arranged so as to rise from the bore for receiving the ventilation device, so that if there are leaks in the ventilation device during operation of the fitting, these are inevitably taken up by the drip water drainage channel. The leakage water then flows through the drip water pipe out of the building wall to the rear of the cover rosette.

Von hier kann das Leckwasser durch eine vorgesehene Öffnung an der Unterkante der Rosette abfließen.From here, the leakage water can be provided by a Drain the opening at the bottom edge of the rosette.

Das in Fig. 1 bis 3 dargestellte Unterputz-Anschlußstück 1 weist zwei diametral gegenüberliegende waagerechte Anschlüsse 14,15 für das zufließende Kalt- und Warmwasser auf. Die Anschlüsse 14,15 sind jeweils mit einem Anschlußkanal für Kalt- und Warmwasser 133,134 in einer Platte 13 verbunden. An der Platte 13 ist Stirnseitig eine Mischventilkartusche 3 mit Spannschrauben 31, die in Gewindebohrungen 311 einschraubbar sind, befestigbar, wie es insbesondere aus Fig. 1 und 2 der Zeichnung zu entnehmen ist. Das in der Mischventilkartusche 3 erzeugte Mischwasser wird über einen Mischwasseranschlußkanal 135 in der Platte 13 dem Unterputz-Anschlußstück 1 wieder zugeführt, und über die vertikal übereinander angeordneten Mischwasseranschlüsse 16 verschiedenen Verbrauchern zugeleitet.
Die Platte 13 ist mit Schrauben 130 und Dichtringen 131 an einer parallel zur Gebäudewand 100 ausgebildeten Anschlußfläche 10 des Unterputz-Anschlußstücks 1 befestigt, wobei der Mischwasseranschlußkanal 135 in eine von der Anschlußfläche 10 ausgehende Bohrung 11 mündet, in der eine als Baueinheit ausgebildete Belüftungseinrichtung 2 angeordnet ist, wie es insbesondere aus Fig. 2 zu entnehmen ist. Die Bohrung 11 ist hierbei waagerecht in dem Unterputz-Anschlußstück 1 ausgebildet und mündet in einer stromabwärts angeordneten Querbohrung 110, die - von der Schnittstelle ausgehend - ansteigend zu beiden Seiten aus dem Unterputz-Anschlußstück 1 herausgeführt ist und somit den stromabwärts gelegenen Bereich der Bohrung 11 mit der Atmosphäre verbindet. An der am tiefsten gelegenen Stelle der Querbohrung 110 ist ein Tropfwasserabflußkanal 12 in dem Unterputzanschlußstück 1 ausgebildet, der in eine ebenfalls mit Gefälle angeordnete Tropfwasserleitung 121 mündet.The flush-mounted connector 1 shown in FIGS. 1 to 3 has two diametrically opposed horizontal connections 14, 15 for the incoming cold and hot water. The connections 14, 15 are each connected to a connection channel for cold and hot water 133, 134 in a plate 13. A mixing valve cartridge 3 with clamping screws 31, which can be screwed into threaded bores 311, can be fastened to the face of the plate 13, as can be seen in particular from FIGS. 1 and 2 of the drawing. The mixed water generated in the mixing valve cartridge 3 is fed back to the flush-mounted connection piece 1 via a mixed water connection channel 135 in the plate 13, and fed to different consumers via the mixed water connections arranged vertically one above the other.
The plate 13 is fastened with screws 130 and sealing rings 131 to a connection surface 10 of the flush-mounted connection piece 1 which is formed parallel to the building wall 100, the mixed water connection channel 135 opening into a bore 11 starting from the connection surface 10, in which a ventilation device 2 designed as a structural unit is arranged is, as can be seen in particular from FIG. 2. The bore 11 is formed horizontally in the flush-mounted connection piece 1 and opens into a downstream transverse bore 110 which, starting from the interface, leads out of the flush-mounted connection piece 1 in an increasing manner on both sides and thus the downstream region of the bore 11 connects with the atmosphere. At the lowest point of the transverse bore 110, a drip water drainage channel 12 is formed in the flush-mounted connection piece 1, which opens into a drip water line 121 which is also arranged at a slope.

Die Belüftungseinrichtung 2 ist dabei in einem zylindrischen Gehäuse 23 angeordnet, wie es aus Fig. 2 und insbesondere aus Fig. 4 zu entnehmen ist. In dem Gehäuse 23 sind in Ringnuten am Außenmantel O-Ringe 230 angeordnet, mit denen das Gehäuse 23 in der Stecklage in der Bohrung 11 gedichtet ist. Das von der Mischventilkartusche 3 erzeugte Mischwasser gelangt hierbei durch die Zuströmöffnung 203 und den ringförmigen Ventilsitz 201 in das Gehäuse 23 eines Mehrwegeventils 20. Hierbei ist zwischen den beiden Ventilsitzen 201 und 202 ein kugelförmiges Ventilverschlußglied 21 axial beweglich angeordnet. Radial in der Wandung des Gehäuses 23 sind hierbei zwischen den Ventilsitzen 201 und 202 Abströmöffnungen 204 ausgebildet.

Das Mischwasser strömt hierbei axial durch die Zuströmöffnung 203 in das Gehäuse 23 und drückt das kugelförmige Ventilverschlußglied 21 gegen den Ventilsitz 202 und strömt durch die Abströmöffnungen 204 in den Ringraum 1111 und von hier durch den Abflußkanal 111 in die Aufnahmebohrung 118. Je nach Stellung des Wasserverteilventils 4 wird es entweder dem oberen Mischwasseranschluß 16, z. B. zu einer Schlauchbrause, oder über den Verbindungskanal 112 dem unteren Mischwasserauslaß 16, z. B. zu einem Badewanneneinlauf, zugeführt. Tritt nun während eines Wasserzapfvorgangs Unterdruck in den Versorgungsleitungen auf, so wird das kugelförmige Ventilverschlußglied 21 in dem Mehrwegeventil 20 vom Ventilsitz 202 und das kugelförmige Ventilverschlußglied 21 in dem stromabwärts gelegenen Ventil 25 vom Ventilsitz 22 abgehoben und somit eine Verbindung über die Querbohrung 110 mit der Atmosphäre hergestellt. Tritt ein stärkerer Unterdruck in dem Versorgungsleitungsnetz auf, so wird das Ventilverschlußglied 21 im Mehrwegeventil 20 gegen den Ventilsitz 201 gedrückt und verschließt somit den Zugang zu dem Kalt- oder Warmwasserleitungsnetz, so daß ein Rücksaugen von Schmutzwasser ausgeschlossen wird. The cold and Hot water enters through the connection channels 133, 134 in the mixing valve cartridge in the with the help of the operating lever 30 set mixing and quantity setting Mixed water is generated and via the mixed water connection channel 135 in the bore 11 of the flush-mounted connector 1 is delivered. The mixed water flows axially through the inflow opening 203 into the housing 23 and presses the spherical valve closure member 21 against the valve seat 202 and flows through the outflow openings 204 in the annular space 1111 and from here through the drain channel 111 in the mounting hole 118. Depending on the position of the water distribution valve 4, it will either upper mixed water connection 16, z. B. to a hose shower, or via the connecting channel 112 to the lower one Mixed water outlet 16, e.g. B. to a bathtub spout, fed. Now occurs during a water tap Vacuum in the supply lines, so it will spherical valve closure member 21 in the multi-way valve 20 from the valve seat 202 and the spherical valve closure member 21 in the downstream valve 25 lifted off the valve seat 22 and thus a connection via the cross bore 110 with the atmosphere produced. A stronger negative pressure occurs in the supply network on, so the valve closure member 21 in the multi-way valve 20 against the valve seat 201 pressed and thus closes access to the cold or Hot water supply network, so that a suck back of Dirty water is excluded.

Sollte nach einem längeren Betrieb die Belüftungseinrichtung 2 undicht werden oder durch Unterdruckstöße Tropfwasser aus der Belüftungseinrichtung 2 austreten, so gelangt in beiden Fällen das Tropfwasser in den unteren Bereich der Querbohrung 110 und wird von hier unschädlich durch den Tropfwasserabflußkanal 12 und die Tropfwasserleitung 121 aus der Gebäudewand 100 herausgeführt und gelangt unterhalb der Rosette 5 zum Austritt.After a long period of operation, the ventilation device 2 leak or due to vacuum surges Leak drip water from the ventilation device 2, in both cases the dripping water gets into the lower one Area of the transverse bore 110 and becomes harmless from here through the drip water drainage channel 12 and Drip water pipe 121 led out of the building wall 100 and arrives at the outlet below the rosette 5.
