Abstract
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 an inflow opening and at least one outflow opening, with a connection surface for a Water valve is formed.
Ein derartiges Unterputz-Anschlußstück ist durch offenkundige
Vorbenutzung
und aus der Druckschrift DE-A-4 040 667
bekanntgeworden. Hierbei ist
an der Anschlußfläche eine Mischventilkartusche mit
Spannschrauben gedichtet befestigbar, wobei die
Anschlußfläche parallel zur Gebäudewandoberfläche angeordnet
ist. In etwa waagerechter Ebene ist auf jeder
Seite jeweils ein Anschluß für das zufließende Kaltund
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.
Außerdem ist aus der EP-A-0 495 372 eine an einen
Wasch- und/oder Spültisch befestigbare Wasserzapfarmatur
bekannt, bei der im Armaturengehäuse zur Verhinderung
eines Rücksaugens von Brauchwasser eine in einem
zylindrischen Gehäuse angeordnete Belüftungseinrichtung
vorgesehen ist. Die Belüftungseinrichtung ist dabei
über einen Belüftungskanal, der in einer Brauseschlauchführung
und einem rohrförmigen Befestigungsschlauch
mündet, mit der Atmosphäre verbunden.
Ferner ist aus der EP-A-0 392 176 eine Anschlussvorrichtung
bekannt, bei der an einem Anschlussstück eine
Zapfarmatur mit einem am Zapfarmaturengehäuse ausgebildeten
Flansch anschließbar ist.Such a flush-mounted connector has become known through prior public use and from document DE-A-4 040 667. Here, a mixing valve cartridge can be fastened in a sealed manner with clamping screws, the connecting surface being arranged parallel to the surface of the building wall. A connection for the incoming cold and hot water and a connection vertically one above the other for the discharge of mixed water is provided on each side in an approximately horizontal plane. Between the two connections for the discharge of mixed water, the concealed connection piece 'a water distribution valve is arranged in a separate bore, with which the mixed water generated in the mixing valve cartridge can be supplied either to the upper or the lower connection, the water distribution valve being designed such that it automatically returns to a preferred outlet position after the outflowing mixed water has been shut off. If a hand shower with a hose and / or the mixed water outlet is arranged in a bathtub in these flush-mounted fittings, it is necessary to provide separate pipe aerators which prevent dirty water from being sucked back into the supply network in the event of a negative pressure in the supply supply network. The installation of the individual pipe ventilation devices in the outlet lines is relatively complex.
In addition, EP-A-0 495 372 discloses a water tap fitting which can be fastened to a wash basin and / or sink, in which a ventilation device arranged in a cylindrical housing is provided in the fitting housing to prevent the sucking back of used water. The ventilation device is connected to the atmosphere via a ventilation channel, which opens into a shower hose guide and a tubular fastening hose.
Furthermore, a connecting device is known from EP-A-0 392 176, in which a tap fitting with a flange formed on the tap fitting housing can be connected to a connecting piece.
Der Erfindung liegt die Aufgabe zugrunde, bei dem eingangs angegebenen Unterputz-Anschlußstück die Installation der Rohrbelüfter zu vereinfachen, und die Rohrbelüfter kostengünstiger auszubilden.The invention has for its object at the outset specified flush-mounted connector the installation to simplify the tube aerator, and the tube aerator to train more cost-effectively.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen
des Anspruchs 1 gelöst.This object is achieved with the features
of
Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen
2 bis 8 angegeben.Further embodiments of the invention are in the
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. 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 von einem Tropfwasser-Abflußkanal
aufgenommen werden können.
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 Verschlußglieder beider Ventile der Belüftungseinrichtung
werden zweckmäßig als Kugeln ausgebildet. The advantages that can be achieved with the invention are, in particular, that a special installation of tube aerators is no longer required. 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. 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 leaks occur in the ventilation device during operation of the fitting, these can be taken up by a drip water drainage channel.
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 closure members of both valves of the ventilation device are expediently designed as balls.
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 einer Abnahme der Mischventilkartusche 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
der Tropfwasserabflußkanal so ausgebildet
werden, dass er in einer Tropfwasserleitung mündet.
Das Leckwasser kann dann über die Tropfwasserleitung
aus der Gebäudewand heraus zur Rückseite der Abdeckrosette
abgeleitet werden. In a further embodiment of the invention, a snap ring can be provided in the plug-in position in the bore for securely holding the ventilation device 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 removal of the mixing valve cartridge, the ventilation device is easily accessible for maintenance purposes. The arrangement of the ventilation device upstream of a water distribution valve also ensures that both mixed water connections are protected by one ventilation device.
Finally, the drip water drainage channel can advantageously be formed in the flush-mounted connector so that it opens into a drip water pipe. The leakage water can then be drained out of the building wall to the back of the cover rosette via the drip water line.
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.

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

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. In dem Gehäuse 23 ist stromabwärts
hinter dem Mehrwegeventil 20 ein weiteres Ventil
25 angeordnet, dessen kugelförmiges Verschlußglied
21 mit einem ebenfalls ringförmig ausgebildeten Ventilsitz
22 zusammenwirkt. Axial ist das Gehäuse 23 einerseits
von einer Ringschulter in der Bohrung 11 und andererseits
von der Platte 13 gesichert.
Im Bereich der radial ausgebildeten Abströmöffnungen
204 ist in der Bohrung 11 ein Ringraum 1111 ausgebildet,
der über einen Abflußkanal 111 mit einer Aufnahmebohrung
118 für ein Wasserverteilventil 4 verbunden
