Description

Die Erfindung betrifft eine Wasserzapfarmatur, insbesondere für Wasch- und/oder Spültische, mit einem an das Versorgungsleitungsnetz anschließbaren Gehäuse und einem als herausziehbare Schlauchbrause ausgebildeten Wasserauslaß, wobei zur Verhinderung eines Rücksaugens von Brauchwasser über die Schlauchbrause in dem Armaturengehäuse eine Belüftungseinrichtung mit wenigstens einem Verschlußglied vorgesehen ist.
Derartige Einrichtungen sind aus den Druckschriften DE 36 03 503 Al und DE 38 05 462 Al bekannt. Bei diesen in einem Nebenkanal angeordneten Belüftungseinrichtungen ist es erforderlich, in den Zulaufleitungen oder der Mischwasserleitung besondere Drosseln oder Rückschlagventile vorzusehen, um eine Drosselung des Luftvolumenstroms beim Rücksaugvorgang zu erreichen.The invention relates to a water tap, in particular for wash basins and / or sinks, with a housing that can be connected to the supply line network and a water outlet designed as a pull-out hose shower, wherein a ventilation device with at least one closure member is provided in the fitting housing to prevent the suction of process water back through the hose shower is.
Such devices are known from the publications DE 36 03 503 Al and DE 38 05 462 Al. With these ventilation devices arranged in a secondary duct, it is necessary to provide special throttles or check valves in the feed lines or the mixed water line in order to throttle the air volume flow during the suction process.

Der Erfindung liegt die Aufgabe zugrunde, die im Oberbegriff des Anspruchs 1 angegebene Armatur zu verbessern.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Auslaßkanal über ein erstes Verschlußglied der Belüftungseinrichtung geführt ist, wobei das Verschlußglied axial bewegbar zwischen zwei, jeweils Durchtrittsöffnungen umschließenden Ventilsitzen angeordnet und vom ausfließenden Wasser axial angeströmt ist, während die Abströmung des Wassers radial zwischen den beiden Ventilsitzen aus der Belüftungseinrichtung erfolgt und über die untere Durchtrittsöffnung die Verbindung zur Atmosphäre herstellbar ist.
Weitere Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 5 angegeben.The invention has for its object to improve the valve specified in the preamble of claim 1.
This object is achieved in that the outlet channel is guided over a first closure member of the ventilation device, the closure member being axially movable between two valve seats, each enclosing through-openings and being axially flowed against by the outflowing water, while the outflow of water radially between the two valve seats from the ventilation device and the connection to the atmosphere can be established via the lower passage opening.
Further refinements of the invention are specified in claims 2 to 5.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die bei den vorbekannten Belüftungseinrichtungen erforderlichen zusätzlichen Drosseln oder Rückschlagventile zur Minderung des Luftstromvolumens beim Rücksaugen entfallen können, da eine derartige Drosselung mit der vorgeschlagenen Einrichtung zusätzlich erreicht wird.
Außerdem wird mit der erfindungsgemäßen Ausbildung erreicht, daß die Belüftungseinrichtung völlig verdeckt in der Wasserzapfarmatur angeordnet werden kann und somit für den Benutzer unsichtbar ist.The advantages that can be achieved with the invention are, in particular, that the additional throttles or check valves required to reduce the air flow volume when sucking back, which are required in the known ventilation devices, can be dispensed with, since such throttling is additionally achieved with the proposed device.
In addition, it is achieved with the design according to the invention that the ventilation device can be arranged completely concealed in the water tap fitting and is therefore invisible to the user.

An embodiment of the invention is shown in the drawing and will be described in more detail below. It shows
Figure 1
a single-hole sink mixer in longitudinal section;
Figure 2
a part of the sink mixer according to Figure 1 in longitudinal section in an enlarged view during the water tap process;
Figure 3

Die in Figur 1 gezeigte Auslaufarmatur in Form einer Spültischmischbatterie ist mit einem Armaturengehäuse 1 versehen, welches einen rohrförmigen Befestigungssockel 11 aufweist, mit dem sie durch eine Öffnung im Spültisch hindurchgeführt und mit Hilfe von Befestigungsmitteln 110 an dem Spültisch befestigt werden kann. An dem oberhalb des Spültisches verbliebenen Bereich des Armaturengehäuses 1 ist eine schwenkbare Brauseschlauchführung 14 angeordnet, während an der oberen Stirnseite eine Mischventilkartusche 6 befestigt ist, die mit einem in zwei Freiheitsgraden bewegbaren Betätigungsgriff 61 zur Einstellung der Wassertemperatur und zur Regelung der abgegebenen Mischwassermenge versehen ist. Die Zuführung von Kalt- und Warmwasser erfolgt über die Kaltwasserleitung 2 und die Warmwasserleitung 3, die durch den rohrförmigen Befestigungssockel 11 in das Armaturengehäuse 1 hineingeführt und über Kanäle der Mischventilkartusche 6 zugeleitet sind. Das erzeugte Mischwasser wird über eine Mischwasserabflußbohrung 13, einem Auslaßkanal 12 und einem Schlauch 41 einer Schlauchbrause 4 zugeführt, die einerseits als Stationärauslauf in die Brauseschlauchführung 14 eingesteckt und andererseits als herausziehbare Schlauchbrause benutzt werden kann.
In der gestuften Mischwasserabflußbohrung 13 des Armaturengehäuses 1 ist eine Belüftungseinrichtung 5, die in einem etwa zylindrischen Gehäuse 50 angeordnet ist, vorgesehen. Die in dem Gehäuse 50 zusammengefaßte Belüftungseinrichtung 5 kann somit als Baueinheit in die Mischwasserabflußbohrung 13 eingesetzt und entnommen werden. Zur Axialsicherung liegt die Belüftungseinrichtung 5 einerseits an der Schulter in der gestuften Mischwasserabflußbohrung 13 und andererseits - nach dem Aufsetzen - an der Mischventilkartusche 6 an.
Die Belüftungseinrichtung 5 besteht, wie es insbesondere aus den Figuren 2 und 3 zu entnehmen ist, aus zwei lotrecht übereinander angeordneten Verschlußgliedern 51,52, wobei das erste Verschlußglied 51 zwischen zwei Ventilsitzen 53,53a axial beweglich angeordnet ist. Die beiden Verschlußglieder 51,52 sind als Kugeln ausgebildet, wobei das zweite Verschlußglied 52 lediglich mit einem dritten Ventilsitz 53b zusammenwirkt und zur Verhinderung eines Austretens von Tropfwasser dient. Alle drei Ventilsitze umschließen Durchtrittsöffnungen 54, 54a,54b. Das erste kugelförmige Verschlußglied 51 wird durch die Schwerkraft auf den Ventilsitz 53a und das zweite kugelförmige Verschlußglied 52 durch die Schwerkraft auf den Ventilsitz 53b gedrückt. In dieser Position wird somit ein Belüftungskanal 56, der mit der Atmosphäre in Verbindung steht, durch beide Verschlußglieder 51,52 abgesperrt. Zwischen den beiden Ventilsitzen 53 und 53a sind in der Wandung des Gehäuses 50 Ablaufkanäle 55a ausgebildet, die mit dem Auslaßkanal 12 in dem Armaturengehäuse 1 verbunden sind. An dem Auslaßkanal 12 ist stromabwärts der Schlauch 41 für die Schlauchbrause 4 angeschlossen. Der Belüftungskanal 56 führt in das Innere des Armaturengehäuses 1 zu der Brauseschlauchführung 14 und dem rohrförmigen Befestigungssockel 11, wie es insbesondere aus Figur 1 zu entnehmen ist, so daß über die Brauseschlauchführung 14 und dem Befestigungssockel 11 die Verbindung zur Atmosphäre hergestellt ist.The outlet fitting shown in FIG. 1 in the form of a sink mixer is provided with a fitting housing 1 provided, which has a tubular mounting base 11 with which it can be passed through an opening in the sink and fastened to the sink with the aid of fastening means 110. A pivotable shower hose guide 14 is arranged on the area of the faucet housing 1 above the sink, while a mixing valve cartridge 6 is attached to the upper end face and is provided with an actuating handle 61 that can be moved in two degrees of freedom to adjust the water temperature and to regulate the amount of mixed water dispensed. The supply of cold and hot water takes place via the cold water line 2 and the hot water line 3, which are led through the tubular fastening base 11 into the fitting housing 1 and are fed to the mixing valve cartridge 6 via channels. The mixed water generated is fed via a mixed water drain hole 13, an outlet channel 12 and a hose 41 to a hose shower 4, which is inserted into the shower hose guide 14 as a stationary outlet on the one hand and can be used as a pull-out hose shower on the other hand.
A ventilation device 5, which is arranged in an approximately cylindrical housing 50, is provided in the stepped mixed water outflow bore 13 of the fitting housing 1. The ventilation device 5 combined in the housing 50 can thus be inserted and removed as a structural unit in the mixed water drain hole 13. For axial securing, the ventilation device 5 rests on the shoulder on the one hand in the stepped mixed water drain hole 13 and, on the other hand, after the attachment, on the mixing valve cartridge 6.
The ventilation device 5 consists, as can be seen in particular from FIGS. 2 and 3, of two closure members arranged vertically one above the other 51,52, wherein the first closure member 51 is arranged between two valve seats 53,53a axially movable. The two closure members 51, 52 are designed as balls, the second closure member 52 only interacting with a third valve seat 53b and serving to prevent dripping water from escaping. All three valve seats enclose through openings 54, 54a, 54b. The first spherical closure member 51 is pressed by gravity on the valve seat 53a and the second spherical closure member 52 by gravity on the valve seat 53b. In this position, a ventilation channel 56, which is connected to the atmosphere, is blocked by both closure members 51, 52. Between the two valve seats 53 and 53a, drain channels 55a are formed in the wall of the housing 50, which are connected to the outlet channel 12 in the valve body 1. The hose 41 for the hose shower 4 is connected downstream to the outlet channel 12. The ventilation duct 56 leads into the interior of the fitting housing 1 to the shower hose guide 14 and the tubular mounting base 11, as can be seen in particular in FIG. 1, so that the connection to the atmosphere is established via the shower hose guide 14 and the mounting base 11.

Die Einrichtung hat folgende Funktionsweise:
Das in der Mischventilkartusche 6 erzeugte Mischwasser wird über einen Zulaufkanal 55 durch die Durchtrittsöffnung 54 dem ersten Verschlußglied 51 zugeführt und drückt somit zusätzlich zur Schwerkraft das Verschlußglied 51 auf den Ventilsitz 53a. Das angeströmte Mischwasser gelangt danach radial über die Ablaufkanäle 55a in den Auslaßkanal 12 und von hier über den Brauseschlauch 41, der Schlauchbrause 4 mit einem Auslaßmundstück 42 ins Freie. Diese normale Betriebssituation ist in Figur 2 mit den Pfeilen angedeutet.
Tritt nun beim Wasserzapfvorgang, z.B. durch einen Defekt, im Versorgungsleitungsnetz ein Unterdruck bzw. ein Rücksaugen des Wassers auf, so werden die beiden kugelförmigen Verschlußglieder 51,52 durch Vacuum angehoben und es kann Luft über den Belüftungskanal 56 durch die Durchtrittsöffnungen 54b und 54a einströmen, so daß der Auslaßkanal 12 mit der Atmosphäre in Verbindung steht. Das kugelförmige Verschlußglied 51 legt sich hierbei an den oberen Ventilsitz 53 an und drosselt bzw. dichtet die Durchtrittsöffnung 54 ab. Es findet somit eine Trennung des Wasserweges von der Mischventilkartusche 6 zur Schlauchbrause 4 statt. Eventuell vorhandene Undichtigkeiten zum Zulaufkanal 55 werden durch den Lufteintritt über die Durchtrittsöffnung 54b abgebaut, so daß ein Rücksaugen über den Schlauch 41 von der Schlauchbrause 4, die möglicherweise in Brauch- oder Schmutzwasser liegt, ausgeschlossen wird. Die Trennung der Mischventilkartusche 6 von der Schlauchbrause 4 ist in der Figur 3 dargestellt, wobei die Pfeile die Strömungsrichtungen anzeigen.The facility works as follows:
The mixed water generated in the mixing valve cartridge 6 is fed via an inlet channel 55 through the passage opening 54 to the first closure member 51 and thus, in addition to gravity, presses the closure member 51 onto the valve seat 53a. The flow of mixed water then reaches the outlet channel 12 radially via the outlet channels 55a and from here via the shower hose 41, the hose shower 4 with an outlet mouthpiece 42 outdoors. This normal operating situation is indicated by the arrows in FIG. 2.
If a vacuum or suction of the water occurs in the supply line network during the water tap process, for example due to a defect, the two spherical closure members 51, 52 are raised by vacuum and air can flow in via the ventilation duct 56 through the through openings 54b and 54a, so that the outlet channel 12 communicates with the atmosphere. The spherical closure member 51 lies against the upper valve seat 53 and throttles or seals the passage opening 54. There is thus a separation of the water path from the mixing valve cartridge 6 to the hose shower 4. Any leaks to the inlet channel 55 are reduced by the air inlet through the passage opening 54b, so that sucking back through the hose 41 from the hose shower 4, which may be in service or dirty water, is excluded. The separation of the mixing valve cartridge 6 from the hose shower 4 is shown in FIG. 3, the arrows indicating the flow directions.
