Definitions
- the invention relates to a water outlet fitting with a pull-out shower head, with the features of the preamble of claim 1.
- Such a water outlet fitting is used in particular as a kitchen fitting that z. B. is arranged next to a sink.
- the mixed water line initially extends from a mixer unit in the basic fitting housing to below the assembly level. Below it, it continues as a hose that is led back to the basic fitting housing and extends through the basic fitting housing and a pivoting outlet pipe to the crockery shower, which is inserted into a holder at the end of the outlet pipe and can be removed from there.
- the pull-out shower head objects in the sink, or the sink itself, can be cleaned more easily than with a fixed water spout.
- the disadvantage of the known kitchen faucet is that it is cumbersome to assemble.
- the tap hole diameter in the worktop, in the sink, etc. is specified and therefore limited and possibly even further reduced by the assembly sleeve to be connected to the fitting.
- a hose that has the necessary compressive strength and kink resistance to last a long time To ensure safe operation of the valve without leaks, however, has a bending radius that is too large, so that the hose bend does not fit through the tap hole or the assembly sleeve. It is therefore necessary to first detach the hose from the fitting, insert it in one strand through the tap hole, and then anchor it again in the fitting body by hanging, screwing, etc. from below the mounting surface.
- a cold and a hot water inlet pipe must also be accommodated in the cross section available for the implementation. All this work for the production of the hose connections must be carried out in confined spaces, possibly in the interior of a kitchen cabinet.
- US 201808/0178935 A1 shows an arrangement in which a pull-out spray is provided, which is arranged separated from an outlet fitting and / or a mixing valve.
- the mixed water line coming from the mixing valve is divided at a Y-shaped flow divider element into one line that leads to the outlet fitting and another line that leads to the pull-out shower.
- the connection of the hoses must be made below the sink, so that assembly is not facilitated.
- the object of the invention is thus to improve a water outlet fitting with a pull-out shower head in such a way that assembly is facilitated.
- the mixed water line can be completely preassembled.
- it then consists of two hose sections lying next to one another, which are connected to an inner deflection channel via a deflection element.
- the size of the deflection element in Relationship to the size of the fitting and the tap hole. If you look at a cross-sectional plane of the tap hole, the projected outer circumferential surface of the deflecting element together with the hose sections attached to it must be smaller than the tap hole or as a mounting sleeve that is to be connected to the valve housing and which can be inserted into the tap hole.
- a cold water supply line and a hot water supply line there are preferably a cold water supply line and a hot water supply line.
- a hot water supply line there are then at least two lines and two hose sections that can be bundled, i.e. laid so closely together, that they can all be pushed through a common opening on the main body of the fitting, namely from the top, i.e. from the side of a sink or a worktop on which the mixer is placed.
- the deflecting element is either a rigid part, for example made of thermoplastic material, which can be inserted through the available opening without deformation, or it is easily deformable so that it fits through the opening in the deformed state, but the deformation in any case Must be reversible and must not lead to kinking of the inner flow channel.
- a tap hole with an outside diameter of 35 mm + 2 / -1 mm is usually provided, whereby in practice the outside diameter of 34 mm has priority. Accordingly, whenever the fitting is not simply placed onto the tap hole from above, but is mounted via a mounting sleeve with an external thread protruding through the tap hole, a generally circular mounting opening of less than 32 mm is available for the hose to be pushed through.
- the circumference of the deflecting element provided according to the invention together with the hoses attached to it must be correspondingly smaller.
- Hose bend including deflection element can be even smaller, namely so small that the remaining opening area available is sufficient to allow the hose to move. Put simply, the deflection element has such a width or takes up so little area in the plan that it can be pushed through the opening cross-section of the mounting sleeve or the tap hole without any problems.
- the valve can be completely pre-assembled, i.e. with the mixed water hose and both cold and hot water supply lines, and checked for leaks. Only the ends of the feed lines then still hang out, preferably vertically stepped, from the bottom of the mounting sleeve. Fitting, mounting sleeve and all water-carrying lines can be pushed through the tap hole as a unit. As soon as the two inlet lines are screwed to the angle valves, the fitting is fully assembled and ready for use.
- the deflecting element can have hose connection pieces which allow a connection that can be subsequently released. However, it can also be provided that the ends of the hose sections are permanently connected to the hose connector of the deflecting element, e.g. B. by gluing or welding.
- the mixed water line can be designed as a hybrid, in that a first part leading downward from the mixer unit is designed as a rigid tube, in particular a metal tube, which then continues in a hose section.
- the mixed water line can, however, also be formed almost entirely from a flexible hose which is only divided into two sections at the deflection point by the deflection element inserted there.
- the deflecting element is developed in such a way that a functional element can be inserted from the outside which is inserted into the Waterway intervenes.
- This can be a flow limiter, a backflow preventer, a strainer or a silencer. In principle, these elements could be inserted from one of the two hose connection pieces. So that a later exchange of the functional elements is possible without removing the hose sections, the deflecting element should, however, have an externally accessible opening which, for. B. can be closed by a screw plug. If this z. B. is arranged at the apex of the deflection element, no additional space is required within the opening cross-section of the mounting sleeve or the tap hole.
- Figure 1 shows a water outlet fitting 100 in a perspective view from the outside. It comprises a basic housing 10 with a hand lever 14 and an angled outlet pipe 11, at the end of which a dish shower 12 is inserted. The aforementioned parts form that part of the water outlet fitting 100 which is visible after this z. B. is mounted on a countertop or a sink.
- a mounting sleeve 13 is inserted into the basic fitting housing 10 from below. This is hollow on the inside and enables a total of at least four water-carrying pipe sections to be passed through. These are each a cold water and a hot water inlet, which are not shown here, as well as two subsections of a mixed water line.
- the mixed water line has a short section 20 leading from the water outlet fitting 100 to below the assembly level, which is designed as a tube and to which a long section 32 of the hose 30 connects, which leads to the dish shower 12.
- the lower area of the mixed water line with the two hose sections 31, 32 is flexible. As a result, the dish shower 12 can be pulled out of the outlet pipe 11, the shape and length of the mixed water line changing.
- the first part of the mixed water line is formed by a metal pipe 20.
- the metal pipe 20 has a smaller diameter than the hose 30 and thus requires less of the opening cross-section within the mounting sleeve 13.
- the metal pipe 20 is connected to the first hose section 31 of the hose 30 via a connecting element 21.
- a second tube section 32 runs parallel to this.
- the two tube sections 31, 32 are connected to one another via a deflection element 33.
- the deflecting element 33 is Y-shaped and has three hose connection pieces 33.1, 33.2, 33.3.
- Figure 2 shows the water outlet fitting 100 in a side view, the fitting base housing 10 and the mounting sleeve 13 being shown in section to show the course of the mixed water line. This begins in the form of the metal pipe 20 in a bore in the basic fitting housing 10, which is connected to a mixed water outlet of a temperature mixing unit 15, and then continues as a flexible hose.
- the hose section 32 which is passed through the interior of the basic fitting housing 10 and the outlet pipe 11, is pulled upwards, which in turn pulls up its lower end, which is connected to the deflection element 33 . Because the metal tube 20 forms a rigid fastening point with the connecting element 21, the section 31 of the hose 30 is deformed to form a loop, which is indicated by the dashed lines.
- the deflecting element 33 which in the illustrated embodiment is connected to an additional sinking weight 34, is deflected to the side.
- the hybrid design of the mixed water line, consisting of the metal pipe 20 and the adjoining flexible hose 30, make it possible to specify the direction in which the loop 31 'is formed.
- the loop 31 'of the first subsection 31 is formed in a plane parallel to the wall plane, for example in the rear area of a base unit, so that the mobility of the loop 31 'is not hindered by objects or fixtures placed further forward, such as a garbage can.
- Figure 3A shows a first assembly phase.
- the lower parts of the mixed water line in particular the hose sections 33.1, 33.2 with the deflection element 33, are located directly above the upper edge of the mounting sleeve 13.
- the mounting sleeve 13 is shown with the usual sealing rings, support elements and fastening nuts with which the water outlet fitting 100 is attached to the ground will.
- Figure 4 shows parts of a further embodiment of a water outlet fitting 100 'in a perspective view from the outside.
- the basic housing which is identical to the first embodiment, is not shown here, but the mounting sleeve 13, the mixer unit 15 with hand lever 14 and the crockery shower 12 are shown.
- the entire mixed water line which begins at the mixer unit 15, is formed by a hose 30 'which comprises a long and a short hose section 32', 31 'which run parallel at least in the lower area. They are about a U-shaped Deflection element 33 'is connected to two hose connectors 33.1', 33.2 '.
- the Figure 5A shows, the hose sections 33.1 ′, 33.2 ′ with the deflecting element 33 are located directly above the upper edge of the mounting sleeve 13.
- the juxtaposed hose sections 31 ', 32' can be pushed down through the mounting sleeve 13 without any problems, even if a cold water supply and a hot water supply are already in the opening cross-section of the mounting sleeve 13.
- the short hose section 31 'coming from the mixer unit then remains almost immobile in the feedthrough in the mounting sleeve, while the long hose section is moved when the dish shower is pulled in and out.
- the deflecting element is deflected laterally, and a movement similar to that in FIG Figure 2 indicated.
- hose sections 31 ", 32" are connected via a bendable deflection element 33 "which has a hinge axis so that the two hose sections 31", 32 "can be positioned at an acute angle to one another without the water flow being cut off in order to reach 180 °, several deflection elements 33 ′′ can be linked to one another. Or the ends of the tube sections are deformed in such a way that the tube sections can be led away parallel to one another when the joint is bent.
- Fig. 7 shows a possible internal structure of the foldable deflecting element 33 ′′ Figure 6 on average.
- a hose connector 33.1 is to be connected to the hose section 31". It contains an inner flow channel which opens into a transverse bore in a tapered end section 33.3 ".

- the hose connector 33.2 ends in a fork 33.4" in which the tapered end section 33.3 “of the hose connector 33.1” is received.
- the transverse bore in the end section 33.3 is aligned with two internal outlet openings of the flow channel on the fork 33.4". The transfer of the water between the hose connectors 33.1 “, 33.2” is made possible in this way regardless of how the hose connectors 33.1 “, 33.2” are positioned relative to one another by pivoting about an axis 33.5 ".

Description
Die Erfindung betrifft eine Wasserauslaufarmatur mit ausziehbarer Geschirrbrause, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a water outlet fitting with a pull-out shower head, with the features of the preamble of claim 1.
Eine solche Wasserauslaufarmatur wird insbesondere als Küchenarmatur verwendet, die z. B. neben einem Spülbecken angeordnet ist. Die Mischwasserleitung erstreckt sich dabei von einer Mischereinheit im Armaturengrundgehäuse zunächst bis unterhalb der Montageebene. Unterhalb davon setzt sie sich als Schlauch fort, der zum Armaturengrundgehäuse zurückgeführt ist und sich durch das Armaturengrundgehäuse und ein schwenkbares Auslaufrohr hindurch bis zu der Geschirrbrause erstreckt, der am Ende des Auslaufrohrs in eine Halterung eingesteckt ist und von dort entnommen werden kann. Mit der ausziehbaren Geschirrbrause können Gegenstände im Spülbecken, oder das Spülbecken selbst, leichter gereinigt werden als mit einem festen Wasserauslauf.Such a water outlet fitting is used in particular as a kitchen fitting that z. B. is arranged next to a sink. The mixed water line initially extends from a mixer unit in the basic fitting housing to below the assembly level. Below it, it continues as a hose that is led back to the basic fitting housing and extends through the basic fitting housing and a pivoting outlet pipe to the crockery shower, which is inserted into a holder at the end of the outlet pipe and can be removed from there. With the pull-out shower head, objects in the sink, or the sink itself, can be cleaned more easily than with a fixed water spout.
Der Nachteil der bekannten Küchenarmatur besteht in der beschwerlichen Montage. Der Hahnlochdurchmesser in der Arbeitsplatte, im Spülbecken etc. ist vorgegeben und daher begrenzt und ggf. sogar noch durch die mit der Armatur zu verbindende Montagehülse weiter reduziert. Ein Schlauch, der die notwendige Druck- und Knickfestigkeit besitzt, um einen langjährigen sicheren Betrieb der Armatur ohne Leckagen zu gewährleisten, besitzt allerdings einen zu großen Biegeradius, so dass der Schlauchbogen nicht durch das Hahnloch bzw. die Montagehülse passt. Daher ist es erforderlich, den Schlauch zunächst von der Armatur zu lösen, ihn in einem Strang durch das Hahnloch zu stecken, und anschließend von unterhalb der Montagefläche wieder im Armaturengrundkörper durch Einhängen, Einschrauben usw. zu verankern. Außerdem müssen in dem für die Durchführung zur Verfügung stehenden Querschnitt auch noch eine Kalt- und eine Warmwasserzulaufleitung untergebracht werden. All diese Arbeiten für das Herstellen der Schlauchanschlüsse müssen unter beengten Platzverhältnissen, unter Umständen im Innenraum eines Küchenunterschrankes, hergestellt werden.The disadvantage of the known kitchen faucet is that it is cumbersome to assemble. The tap hole diameter in the worktop, in the sink, etc. is specified and therefore limited and possibly even further reduced by the assembly sleeve to be connected to the fitting. A hose that has the necessary compressive strength and kink resistance to last a long time To ensure safe operation of the valve without leaks, however, has a bending radius that is too large, so that the hose bend does not fit through the tap hole or the assembly sleeve. It is therefore necessary to first detach the hose from the fitting, insert it in one strand through the tap hole, and then anchor it again in the fitting body by hanging, screwing, etc. from below the mounting surface. In addition, a cold and a hot water inlet pipe must also be accommodated in the cross section available for the implementation. All this work for the production of the hose connections must be carried out in confined spaces, possibly in the interior of a kitchen cabinet.
Die Aufgabe der Erfindung besteht somit darin, eine Wasserauslaufarmatur mit ausziehbarer Geschirrbrause so zu verbessern, dass die Montage erleichtert wird.The object of the invention is thus to improve a water outlet fitting with a pull-out shower head in such a way that assembly is facilitated.
Diese Aufgabe wird durch eine Wasserauslaufarmatur mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a water outlet fitting with the features of claim 1.
Indem nach der Erfindung in der Mischwasserleitung ein Schlauchbogen geschaffen wird, dessen Breite unabhängig vom Biegeradius des verwendeten Schlauchs ist, kann die Mischwasserleitung komplett vormontiert werden. Sie besteht dann für die Auszugsbrause aus zwei nebeneinander liegenden Schlauchabschnitten, die über ein Umlenkelement mit einem inneren Umlenckanal verbunden sind. Außerdem muss die Größe des Umlenkelements in Beziehung zur Größe der Armatur und zum Hahnloch gesetzt werden. Schaut man sich eine Querschnittsebene des Hahnlochs an, so muss die projizierte äußere Umfangsfläche des Umlenkelements mitsamt der daran angesetzten Schlauchabschnitten kleiner sein als das Hahnloch oder als eine Montagehülse, die mit dem Armaturengehäuse zu verbinden ist und die in das Hahnloch einsetzbar ist.By creating a hose bend in the mixed water line according to the invention, the width of which is independent of the bending radius of the hose used, the mixed water line can be completely preassembled. For the pull-out shower, it then consists of two hose sections lying next to one another, which are connected to an inner deflection channel via a deflection element. In addition, the size of the deflection element in Relationship to the size of the fitting and the tap hole. If you look at a cross-sectional plane of the tap hole, the projected outer circumferential surface of the deflecting element together with the hose sections attached to it must be smaller than the tap hole or as a mounting sleeve that is to be connected to the valve housing and which can be inserted into the tap hole.
Hinzu kommen vorzugsweise eine Kaltwasserzuleitung und eine Warmwasserzuleitung. Es gibt dann also mindestens zwei Leitungen und zwei Schlauchabschnitte, die sich so bündeln lassen, also so eng aneinanderlegen lassen, dass sie alle zusammen durch eine gemeinsame Öffnung am Armaturengrundkörper hindurch gesteckt werden können, und zwar von der Oberseite, also von der Seite einer Spüle oder eine Arbeitsplatte aus, auf der die Armatur aufgesetzt wird.In addition, there are preferably a cold water supply line and a hot water supply line. There are then at least two lines and two hose sections that can be bundled, i.e. laid so closely together, that they can all be pushed through a common opening on the main body of the fitting, namely from the top, i.e. from the side of a sink or a worktop on which the mixer is placed.
Das Umlenkelement ist entweder ein starres Teil, beispielsweise aus thermoplastischem Kunststoff, das ohne Verformung durch die zur Verfügung stehende Öffnung gesteckt werden kann, oder es ist leicht verformbar, so dass es im verformten Zustand durch die Öffnung passt, wobei aber die Verformung in jedem Fall reversibel sein muss und nicht zum Abknicken des inneren Fließkanals führen darf.The deflecting element is either a rigid part, for example made of thermoplastic material, which can be inserted through the available opening without deformation, or it is easily deformable so that it fits through the opening in the deformed state, but the deformation in any case Must be reversible and must not lead to kinking of the inner flow channel.
Im westeuropäischen Raum ist üblicherweise ein Hahnloch mit einem Außendurchmesser von 35 mm +2/-1 mm vorgesehen, wobei in der Praxis der Au-βendurchmesser 34 mm Priorität genießt. Entsprechend steht immer dann, wenn die Armatur nicht einfach von oben auf das Hahnloch aufgesetzt ist, sondern über eine durch das Hahnloch hindurch ragende Montagehülse mit Außengewinde montiert wird, eine im Allgemeinen kreisrunde Montageöffnung für das Durchschieben des Schlauchs von weniger als 32 mm zur Verfügung. Der Umkreis des nach der Erfindung vorgesehene Umlenkelements samt der daran angebrachten Schläuche muss entsprechend kleiner sein. Sofern innerhalb der Montagehülse bereits Platz für andere Komponenten beansprucht ist, muss die in die Hahnlochebene projizierte Fläche des Schlauchbogens samt Umlenkelement noch kleiner sein, nämlich so klein, dass die zur Verfügung stehende restliche Öffnungsfläche ausreichend ist, um die Schlauchbewegung zu ermöglichen. Vereinfacht gesagt, besitzt das Umlenkelement eine solche Breite bzw. nimmt so wenig Fläche im Grundriss ein, dass es problemlos durch den Öffnungsquerschnitt der Montagehülse oder des Hahnlochs hindurch geschoben werden kann.In Western Europe, a tap hole with an outside diameter of 35 mm + 2 / -1 mm is usually provided, whereby in practice the outside diameter of 34 mm has priority. Accordingly, whenever the fitting is not simply placed onto the tap hole from above, but is mounted via a mounting sleeve with an external thread protruding through the tap hole, a generally circular mounting opening of less than 32 mm is available for the hose to be pushed through. The circumference of the deflecting element provided according to the invention together with the hoses attached to it must be correspondingly smaller. If space is already required for other components within the mounting sleeve, the area of the projected into the tap hole level must be Hose bend including deflection element can be even smaller, namely so small that the remaining opening area available is sufficient to allow the hose to move. Put simply, the deflection element has such a width or takes up so little area in the plan that it can be pushed through the opening cross-section of the mounting sleeve or the tap hole without any problems.
Weil kein nachträglicher Anschluss des Endes der Mischwasserleitung am Armaturengrundgehäuse mehr hergestellt werden muss, kann die Armatur komplett, also mit dem Mischwasserschlauch und mit beiden Kalt- und Warmwasserzulaufleitungen vormontiert und auf Dichtigkeit geprüft werden. Nur die Enden der Zulaufleitungen hängen dann noch, vorzugsweise vertikal gestuft, unten aus der Montagehülse heraus. Armatur, Montagehülse und alle wasserführenden Leitungen können als Einheit durch das Hahnloch gesteckt werden. Sobald die beiden Zulaufleitungen mit den Eckventilen verschraubt sind, ist die Armatur fertig montiert und betriebsbereit.Because the end of the mixed water pipe no longer needs to be connected to the basic valve body, the valve can be completely pre-assembled, i.e. with the mixed water hose and both cold and hot water supply lines, and checked for leaks. Only the ends of the feed lines then still hang out, preferably vertically stepped, from the bottom of the mounting sleeve. Fitting, mounting sleeve and all water-carrying lines can be pushed through the tap hole as a unit. As soon as the two inlet lines are screwed to the angle valves, the fitting is fully assembled and ready for use.
Das Umlenkelement kann Schlauchanschlussstutzen aufweisen, die eine nachträglich lösbare Verbindung erlauben. Es kann aber auch vorgesehen sein, die Enden der Schlauchabschnitte mit den Schlauchanschlussstutzen des Umlenkelements dauerhaft zu verbinden, z. B. durch Verkleben oder Verschweißen.The deflecting element can have hose connection pieces which allow a connection that can be subsequently released. However, it can also be provided that the ends of the hose sections are permanently connected to the hose connector of the deflecting element, e.g. B. by gluing or welding.
Die Mischwasserleitung kann hybrid ausgebildet sein, indem ein erster, von der Mischereinheit nach untern führender Teil als starres Rohr, insbesondere Metallrohr, ausgebildet ist, das sich dann in einem Schlauchabschnitt fortsetzt.The mixed water line can be designed as a hybrid, in that a first part leading downward from the mixer unit is designed as a rigid tube, in particular a metal tube, which then continues in a hose section.
Die Mischwasserleitung kann aber auch nahezu vollständig aus einem flexiblen Schlauch gebildet sein, der lediglich an der Umlenkstelle durch das dort eingesetzte Umlenkelement in zwei Teilabschnitte geteilt ist.The mixed water line can, however, also be formed almost entirely from a flexible hose which is only divided into two sections at the deflection point by the deflection element inserted there.
Das Umlenkelement ist in einer bevorzugten Ausführungsform so weitergebildet, dass von außen ein Funktionselement einsetzbar ist, das in den Wasserweg eingreift. Hierbei kann es sich um einen Durchflussbegrenzer, einen Rückflussverhinderer, ein Sieb oder einen Schalldämpfer handeln. Grundsätzlich könnten diese Elemente von einem der beiden Schlauchanschlussstutzen aus eingesetzt werden. Damit ein späterer Austausch der Funktionselemente ohne Abnehmen der Schlauchabschnitte möglich ist, sollte das Umlenkelement jedoch eine von außen zugängliche Öffnung besitzen, die z. B. über einen Schraubstopfen verschließbar ist. Wenn diese z. B. am Scheitelpunkt des Umlenkelements angeordnet ist, wird kein zusätzliche Platz innerhalb des Öffnungsquerschnitts der Montagehülse bzw. des Hahnlochs beansprucht.In a preferred embodiment, the deflecting element is developed in such a way that a functional element can be inserted from the outside which is inserted into the Waterway intervenes. This can be a flow limiter, a backflow preventer, a strainer or a silencer. In principle, these elements could be inserted from one of the two hose connection pieces. So that a later exchange of the functional elements is possible without removing the hose sections, the deflecting element should, however, have an externally accessible opening which, for. B. can be closed by a screw plug. If this z. B. is arranged at the apex of the deflection element, no additional space is required within the opening cross-section of the mounting sleeve or the tap hole.

Von unten ist eine Montagehülse 13 in das Armaturengrundgehäuse 10 eingesetzt. Diese ist von innen hohl und ermöglicht die Durchführung von insgesamt mindestens vier wasserführenden Leitungsabschnitten. Dabei handelt es sich um jeweils einen Kaltwasser- und einen Warmwasserzulauf, welche hier nicht dargestellt sind, sowie um zwei Teilabschnitte einer Mischwasserleitung. Die Mischwasserleitung besitzt einen von der Wasserauslaufarmatur 100 bis unterhalb der Montageebene führenden, kurzen Teilabschnitt 20, der als Rohr ausgebildet ist und an den sich ein langer Teilabschnitt 32 des Schlauchs 30 anschließt, der zur Geschirrbrause 12 führt. Der untere Bereich der Mischwasserleitung mit den beiden Schlauchabschnitten 31, 32 ist flexibel. Dadurch kann die Geschirrbrause 12 aus dem Auslaufrohr 11 herausgezogen werden, wobei sich Form und Länge der Mischwasserleitung ändern.A mounting
In dem dargestellten Ausführungsbeispiel ist der erste Teil der Mischwasserleitung durch ein Metallrohr 20 gebildet. Das Metallrohr 20 besitzt einen kleineren Durchmesser als der Schlauch 30 und benötigt somit weniger Anteil am Öffnungsquerschnitt innerhalb der Montagehülse 13. Das Metallrohr 20 ist über ein Verbindungselement 21 mit dem ersten Schlauchabschnitt 31 des Schlauchs 30 verbunden. Parallel dazu verläuft ein zweiter Schlauchabschnitt 32. Die beiden Schlauchabschnitte 31, 32 sind über ein Umlenkelement 33 miteinander verbunden. Das Umlenkelement 33 ist Y-förmig und besitzt drei Schlauchanschlussstutzen 33.1, 33.2, 33.3.In the exemplary embodiment shown, the first part of the mixed water line is formed by a
Wird die Geschirrbrause 12 aus dem Auslaufrohr 11 herausgezogen, so wird der Schlauchabschnitt 32, welcher durch das Innere des Armaturengrundgehäuses 10 und des Auslaufrohrs 11 hindurchgeführt ist, nach oben gezogen, wodurch wiederum sein unteres Ende, welches mit dem Umlenkelement 33 verbunden ist, hochgezogen wird. Dadurch, dass das Metallrohr 20 mit dem Verbindungselement 21 einen starren Befestigungspunkt bildet, verformt sich der Teilabschnitt 31 des Schlauchs 30 zu einer Schlaufe, die durch die gestrichelten Linien angedeutet ist.If the
Das Umlenkelement 33, das bei dem dargestellten Ausführungsbeispiel mit einem zusätzlichen Senkgewicht 34 verbunden ist, wird zur Seite ausgelenkt. Die hybride Ausbildung der Mischwasserleitung, bestehend aus dem Metallrohr 20 und dem sich anschließenden flexiblen Schlauch 30 ermöglichen es, die Richtung vorzugeben, in welcher sich die Schlaufe 31' ausbildet. In einer üblichen Anordnung der Wasserauslaufarmatur 100, bei der die Mittelachse des Handhebels 14 parallel zur Wandfläche hinter der Spüle ausgerichtet ist, bildet sich die Schlaufe 31' des ersten Teilabschnitts 31 in einer Ebene parallel zur Wandebene aus, also beispielsweise im rückwärtigen Bereich eines Unterschranks, so dass die Beweglichkeit der Schlaufe 31' durch weiter vorn platzierte Gegenstände oder Einbauten wie einen Mülleimer nicht behindert wird.The deflecting
Erfindungswesentlich ist, dass beide Schlauchabschnitte 31, 32 und ggf. auch die Kopplungsstelle des ersten und des zweiten Teilabschnitts 31,32 über das Umlenkelement 33 einschließlich aller eventuell daran angebrachten Zusatzelemente wie dem Senkgewicht 34 nur eine geringe Breite benötigen, die kleiner als der lichte Öffnungsdurchmesser der Montagehülse 13 ist. Dadurch kann, wie in den folgenden

Bei dieser Ausführungsform ist die gesamte Mischwasserleitung, die ihren Anfang bei der Mischereinheit 15 hat, durch einen Schlauch 30' gebildet, der einen langen und einen kurzen Schlauchabschnitt 32', 31' umfasst, die zumindest im unteren Bereich parallel verlaufen. Sie sind über ein U-förmiges Umlenkelement 33' mit zwei Schlauchanschlussstutzen 33.1', 33.2' verbunden.In this embodiment, the entire mixed water line, which begins at the
