Definitions
- the present invention relates to a sanitary fitting.
- Such sanitary fittings serve to provide a liquid as needed, for example in showers, bathtubs, sinks or wash basins.
- Sanitary fittings with at least one shower head are known, with which a liquid, in particular water, can be dispensed in different jet types, for example normal jet, full jet, massage jet, rain jet, etc., for example from US 2015/0238984 A1 and WO 2011/037115 A1 .
- shower heads usually have different jet formers.
- the liquid must be directed from an inlet of the shower head via a pipe system of the shower head to one of the jet formers of the shower head.
- valves are arranged in the pipe system.
- complex mechanics are usually required in the shower heads.
- the different jet types can only be adjusted by a user directly on the shower head. Changing the jet types can therefore be complex if accessibility to the shower head is limited. This can be the case, for example, if the shower head is attached at a great height in a shower.
- valves are designed in the manner of diaphragm valves.
- diaphragm valves can be operated by control valves or so-called pilot valves, which can be arranged in areas that are easily accessible to the user. Pilot valves are made, for example, of WO91/16848 A1 known.
- the control valves are arranged in control channels that connect the counter pressure chambers of the individual diaphragm valves with a drain of the shower head, bypassing the diaphragm valves.
- the control channels lead from the counter pressure chambers in the shower head to the control valves and from the control valves back into the shower head. This means that two
- the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a sanitary fitting whose control channels have a reduced number of interfaces to the shower head.
- a sanitary fitting which has at least the features of independent claim 1 contributes to this.
- the sanitary fitting has a shower head and is used to provide a liquid, in particular water, as required, for example in showers, bathtubs, sinks or wash basins.
- the shower head can be designed, for example, in the manner of a hand shower and/or in the manner of a shower head.
- the sanitary fitting also comprises at least one inlet, via which the liquid can be supplied to a plurality of diaphragm valves of the shower head.
- the at least one inlet can be designed at least partially as a pipe, (flexible) hose and/or as a liquid guide in the shower head.
- the shower head can also be connected to a liquid source via the at least one inlet.
- a plurality of outlets of the shower head or the plurality of diaphragm valves can be closed or opened by the plurality of diaphragm valves.
- the various outlets each lead to a jet generator for a specific jet type.
- a specific jet type of the shower can thus be activated by opening one of the diaphragm valves.
- the diaphragm valves each comprise a diaphragm and a counterpressure chamber connected to at least one inlet.
- the diaphragm valves can be controlled by a (common and/or single) control.
- the control is particularly designed to control the operation of the diaphragm valves jointly or separately.
- the control is particularly designed to activate and/or deactivate and/or maintain (for a predeterminable period of time) one or more valve positions for (each) diaphragm valve.
- the control comprises a plurality of control channels with a plurality of control valves. The control channels connect the counterpressure chamber of the diaphragm valves to the at least one inlet, bypassing the diaphragm valves' diaphragms.
- the liquid can flow from an inlet channel and/or an inlet chamber of the respective diaphragm valve via a compensating bore in the diaphragm valves' diaphragms and/or other components of the shower head into the counterpressure chamber of the diaphragm valves, so that the liquid has the same liquid pressure on both sides of the diaphragms. Since the diaphragms delimit the counterpressure chambers with a larger area than the inlet channels and/or inlet chambers of the diaphragm valves, the force on the membranes resulting from the fluid pressure of the fluid in the back pressure chambers is greater than the force resulting from the fluid pressure of the fluid in the inlet channels and/or inlet chambers.
- a control channel leads from the back pressure chambers (in each case) to one of the control valves.
- the control valves can be, for example, electrically operated valves, solenoid valves or manually operated valves.
- the control valves can be arranged in the shower head or outside the shower head, for example in a wall. If the control valves are located outside the shower head, the control channels can be at least partially designed as (flexible) hose lines. By opening the control valves, the fluid can flow out of the back pressure chambers via the control channels, so that the fluid pressure in the back pressure chambers drops. This lifts the membranes off the membrane seat, so that the membrane valves open.
- the liquid pressure in the back pressure chamber should drop sufficiently due to the stationary state that occurs between the liquid flowing in via the compensation opening and the liquid flowing out of the back pressure chamber via the control channels.
- the majority of control channels can be larger or have a larger diameter than the compensation holes.
- the control channels can be connected to a suction device of the at least one inlet.
- the suction device By means of the suction device, the liquid is in particular removed from the control channels or the back pressure chambers of the diaphragm valves when the corresponding control valves are open.
- the suction device can comprise a vortex chamber.
- the vortex chamber can in particular be cylindrical, with the inlet opening tangentially into the vortex chamber, so that the liquid flowing into the vortex chamber forms a vortex in the vortex chamber.
- the liquid exits the vortex chamber through an outlet opening on a first end face of the (cylindrical) vortex chamber.
- the control channels can be connected to the vortex chamber via an inlet opening on a second end face of the vortex chamber.
- the inlet opening in particular has a diameter that is smaller than a diameter of the outlet opening on the opposite first end face of the vortex chamber.
- the liquid from the control channels is sucked into the vortex chamber through the inlet opening and leaves the vortex chamber with the liquid from the inlet through the outlet opening.
- the inlet extends from the outlet opening to the shower head.
- the suction device can comprise a Venturi nozzle.
- the Venturi nozzle can in particular be designed in the manner of a water jet pump.
- a cross-section of the at least one inlet can in particular narrow in the area of the suction device, with the control channels opening into the area with the reduced cross-section.
- the speed of the liquid flowing through the suction device increases in the area with the reduced cross-section, whereby the (static) pressure in the control channels drops, so that the liquid is sucked from the control channels into the suction device.
- the suction device can be arranged outside the shower head.
- the suction device can be arranged, for example, in a wall to which the sanitary fitting and/or the shower head are attached.
- the majority of diaphragm valves are arranged in the shower head.
- the majority of diaphragm valves are arranged in particular within a housing of the shower head and/or formed using components of the shower head.
- the control valves can be arranged outside the shower head.
- the control valves can be arranged in a wall to which the sanitary fitting and/or the shower head are attached.
- the control valves can also be arranged in an area in which they can be easily operated by the user of the sanitary fitting.
- the plurality of control channels can open into a common return channel. In this case, the control channels open into the at least one inlet via the common return channel.
- the outlets can each be connected to a jet former on the shower head.
- fluid channels can be formed in the shower head that connect the outlets of the individual diaphragm valves with the respective jet formers.
- the Fig.1 shows a sanitary fitting 1 with a shower head 2, which can be an overhead shower, for example.
- a first membrane valve 4 a second diaphragm valve 5 and a third diaphragm valve 6 are arranged.
- a liquid can be supplied to the diaphragm valves 4, 5, 6 via an inlet 3.
- the diaphragm valves 4, 5, 6 are designed identically here. The functioning of the diaphragm valves 4, 5, 6 is therefore only described below using the first diaphragm valve 4.
- the liquid flows from the inlet 3 first into an inlet chamber 24 of the first diaphragm valve 4, which is designed in a ring shape here.
- the liquid then flows from the first inlet chamber 4 through a compensating bore 25 in a membrane 7 into a back pressure chamber 11.
- the back pressure chamber 11 is located on a side of the membrane 7 opposite the inlet chamber 24.
- the membrane 7 is shown here in a closed state. When the membrane 7 is closed, the same liquid pressure prevails in the inlet chamber 24 and the back pressure chamber 11. Since the membrane 7 delimits the back pressure chamber 11 with a larger area than the inlet chamber 24, the force on the membrane 7 resulting from the liquid pressure of the liquid in the back pressure chamber 11 is greater than the force resulting from the liquid pressure of the liquid in the inlet chamber 24. This presses the membrane 7 onto an annular valve seat 26.
- the valve seat 26 is formed on a longitudinal end of a first outlet 8.
- the diaphragm valves 4, 5, 6 can be controlled by a control 12.
- the control 12 comprises a first control channel 13 with a first control valve 16, a second control channel 14 with a second control valve 17 and a third control channel 15 with a third control valve 18.
- the control channels 13, 14, 15 each have only a single interface 27 to the shower head 2 and open into a common return channel 20.
- the first control valve 16 is open, the liquid flows from the counterpressure chamber 11 via the first control channel 16 and the return channel 20 to a suction device 19 which is arranged in the inlet 3.
- the suction device 19 sucks the liquid from the counterpressure chamber 11 back into the inlet 3, via which the liquid can be fed back to the diaphragm valves 4, 5, 6.
- a second outlet 9 of the second diaphragm valve 5 is connected to a second jet former 22 of the shower head 2 and a third outlet 10 of the third diaphragm valve 6 is connected to a third jet former 23 of the shower head 2.
- the liquid can thus be fed to the jet formers 21, 22, 23 in a targeted manner by means of the control 12 and the diaphragm valves 4, 5, 6 depending on the desired type of jet.
- the Fig.2 shows schematically a vortex chamber 28 of the suction device 19.
- the vortex chamber 28 is cylindrical, with the inlet 3 opening tangentially into the vortex chamber 28, so that the liquid flowing into the vortex chamber 28 forms a vortex in the vortex chamber 28.
- the liquid exits the vortex chamber 28 through an outlet opening 29 on a first end face 30 of the vortex chamber 28.
- the Fig.1 shown control channels 13, 14, 15 or the return channel 20 are connected to the vortex chamber 28 via an inlet opening 32 on a second end face 31 of the vortex chamber 28.
- the inlet opening 31 has a diameter that is smaller than a diameter of the outlet opening 29 on the opposite first end face 30 of the vortex chamber 28.
- the liquid from the control channels 13, 14, 15 or the return channel 20 is sucked through the inlet opening 32 into the vortex chamber 28 and leaves the vortex chamber 28 with the liquid from the inlet 3 through the outlet opening 29.
- the inlet 3 extends from the outlet opening 29 further to the Fig.1 shower head shown 2.
- control channels have a reduced number of interfaces to the shower head, which reduces the assembly effort and the manufacturing costs of the sanitary fitting.

Aufgabe der Erfindung ist es daher, die mit Bezug auf den Stand der Technik geschilderten Probleme zumindest teilweise zu lösen und insbesondere eine Sanitärarmatur anzugeben, deren Steuerkanäle eine reduzierte Anzahl von Schnittstellen zum Brausekopf aufweisen.The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to provide a sanitary fitting whose control channels have a reduced number of interfaces to the shower head.
Diese Aufgabe wird gelöst mit einer Sanitärarmatur gemäß den Merkmalen des unabhängigen Patentanspruchs. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.This object is achieved with a sanitary fitting according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent patent claims.
Darüber hinaus werden die in den Patentansprüchen angegebenen Merkmale in der Beschreibung näher präzisiert und erläutert, wobei weitere bevorzugte Ausgestaltungen der Erfindung dargestellt werden.Furthermore, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.
Hierzu trägt eine Sanitärarmatur bei, die zumindest die Merkmale des unabhängigen Anspruchs 1 aufweist.A sanitary fitting which has at least the features of independent claim 1 contributes to this.
Die Sanitärarmatur weist einen Brausekopf auf und dient der bedarfsgerechten Bereitstellung einer Flüssigkeit, insbesondere Wasser, an beispielsweise Duschen, Badewannen, Spülbecken oder Waschbecken. Der Brausekopf kann beispielsweise nach Art einer Handbrause und/oder nach Art eines Duschkopfs ausgebildet sein. Weiterhin umfasst die Sanitärarmatur zumindest einen Zulauf, über den die Flüssigkeit einer Mehrzahl von Membranventilen des Brausekopfs zuführbar ist. Der zumindest eine Zulauf kann zumindest teilweise als Rohr, (flexibler) Schlauch und/oder als Flüssigkeitsführung in dem Brausekopf ausgebildet sein. Weiterhin ist über den zumindest einen Zulauf der Brausekopf mit einer Flüssigkeitsquelle verbindbar. Durch die Mehrzahl von Membranventilen sind eine Mehrzahl von Abläufen des Brausekopfs bzw. der Mehrzahl von Membranventilen verschließbar oder öffenbar. Die verschiedenen Abläufe führen jeweils zu einem Strahlbildner für eine spezifische Strahlart. Somit ist durch Öffnen eines der Membranventile eine bestimmte Strahlart der Brause aktivierbar. Die Membranventile umfassen jeweils eine Membran und jeweils eine mit dem zumindest einen Zulauf verbundene Gegendruckkammer.The sanitary fitting has a shower head and is used to provide a liquid, in particular water, as required, for example in showers, bathtubs, sinks or wash basins. The shower head can be designed, for example, in the manner of a hand shower and/or in the manner of a shower head. The sanitary fitting also comprises at least one inlet, via which the liquid can be supplied to a plurality of diaphragm valves of the shower head. The at least one inlet can be designed at least partially as a pipe, (flexible) hose and/or as a liquid guide in the shower head. The shower head can also be connected to a liquid source via the at least one inlet. A plurality of outlets of the shower head or the plurality of diaphragm valves can be closed or opened by the plurality of diaphragm valves. The various outlets each lead to a jet generator for a specific jet type. A specific jet type of the shower can thus be activated by opening one of the diaphragm valves. The diaphragm valves each comprise a diaphragm and a counterpressure chamber connected to at least one inlet.
Weiterhin sind die Membranventile durch eine (gemeinsame und/oder einzige) Steuerung steuerbar. Die Steuerung ist insbesondere eingerichtet, den Betrieb der Membranventile gemeinsam oder separat zu steuern. Die Steuerung ist insbesondere dazu eingerichtet, eine oder mehrere Ventilstellung(en) bei einem (jeden) Membranventil zu aktivieren und/oder zu deaktivieren und/oder (für einen vorgebaren Zeitraum) zu halten. Die Steuerung umfasst eine Mehrzahl von Steuerkanälen mit einer Mehrzahl von Steuerventilen. Die Steuerkanäle verbinden die Gegendruckkammer der Membranventile unter Umgehung der Membranen der Membranventile mit dem zumindest einen Zulauf. Die Flüssigkeit kann aus einem Zulaufkanal und/oder einer Zulaufkammer des jeweiligen Membranventils über eine Ausgleichsbohrung in den Membranen der Membranventile und/oder sonstigen Komponenten des Brausekopfs in die Gegendrucckammer der Membranventile fließen, sodass die Flüssigkeit auf beiden Seiten der Membranen den gleichen Flüssigkeitsdruck aufweist. Da die Membranen die Gegendruckkammern mit einer größeren Fläche begrenzen als die Zulaufkanäle und/oder Zulaufkammern der Membranventile, ist die aus dem Flüssigkeitsdruck der Flüssigkeit in den Gegendruckkammern resultierende Kraft auf die Membranen größer als die aus dem Flüssigkeitsdruck der Flüssigkeit in den Zulaufkanälen und/oder Zulaufkammern resultierende Kraft. Hierdurch werden die Membrane auf einen Ventilsitz gedrückt, sodass die Membranventile geschlossen sind. Von den Gegendruckkammern führt (jeweils) ein Steuerkanal zu einem der Steuerventile. Bei den Steuerventilen kann es sich beispielsweise um elektrisch betätigbare Ventile, Magnetventile oder manuell betätigbare Ventile handeln. Die Steuerventile können in dem Brausekopf oder außerhalb des Brausekopfs, beispielsweise in einer Wand, angeordnet sein. Befinden sich die Steuerventile außerhalb des Brausekopfs, können die Steuerkanäle zumindest teilweise als (flexible) Schlauchleitungen ausgebildet sein. Durch Öffnen der Steuerventile kann die Flüssigkeit über die Steuerkanäle aus den Gegendruckkammern abfließen, sodass der Flüssigkeitsdruck in den Gegendruckkammern sinkt. Hierdurch werden die Membrane von dem Membransitz abgehoben, sodass sich die Membranventile öffnen. Damit das Membranventil öffnet, sollte der Flüssigkeitsdruck in der Gegendruckkammer durch den stationären Zustand, der sich zwischen der über die Ausgleichsöffnung nachfließenden Flüssigkeit und der über die Steuerkanäle aus der Gegendruckkammer abfließenden Flüssigkeit einstellt, stark genug abfallen. Hierzu kann die Mehrzahl von Steuerkanälen größer bzw. mit einem größeren Durchmesser ausgeführt sein als die Ausgleichsbohrungen. Durch die Verwendung einer Mehrzahl von Membranventilen können daher verschiedene Strahlarten ohne aufwendige Mechanik eingestellt werden. Zudem kann die Steuerung zur Einstellung der verschiedenen Strahlarten entfernt von dem Brausekopf an einem Ort angeordnet werden, an dem diese durch einen Benutzer leicht zugänglich ist. Die einzelnen Steuerkanäle führen stromabwärts der Steuerventile nicht zurück in den Brausekopf, sondern münden stromaufwärts des Brausekopfs in den zumindest einen Zulauf. Hierdurch sind an dem Brausekopf entsprechend wenigere Schnittstellen zur Rückführung der Flüssigkeit erforderlich, weil die Flüssigkeit über den zumindest einen Zulauf zum Brausekopf rückführbar ist.Furthermore, the diaphragm valves can be controlled by a (common and/or single) control. The control is particularly designed to control the operation of the diaphragm valves jointly or separately. The control is particularly designed to activate and/or deactivate and/or maintain (for a predeterminable period of time) one or more valve positions for (each) diaphragm valve. The control comprises a plurality of control channels with a plurality of control valves. The control channels connect the counterpressure chamber of the diaphragm valves to the at least one inlet, bypassing the diaphragm valves' diaphragms. The liquid can flow from an inlet channel and/or an inlet chamber of the respective diaphragm valve via a compensating bore in the diaphragm valves' diaphragms and/or other components of the shower head into the counterpressure chamber of the diaphragm valves, so that the liquid has the same liquid pressure on both sides of the diaphragms. Since the diaphragms delimit the counterpressure chambers with a larger area than the inlet channels and/or inlet chambers of the diaphragm valves, the force on the membranes resulting from the fluid pressure of the fluid in the back pressure chambers is greater than the force resulting from the fluid pressure of the fluid in the inlet channels and/or inlet chambers. This presses the membranes onto a valve seat, so that the membrane valves are closed. A control channel leads from the back pressure chambers (in each case) to one of the control valves. The control valves can be, for example, electrically operated valves, solenoid valves or manually operated valves. The control valves can be arranged in the shower head or outside the shower head, for example in a wall. If the control valves are located outside the shower head, the control channels can be at least partially designed as (flexible) hose lines. By opening the control valves, the fluid can flow out of the back pressure chambers via the control channels, so that the fluid pressure in the back pressure chambers drops. This lifts the membranes off the membrane seat, so that the membrane valves open. In order for the diaphragm valve to open, the liquid pressure in the back pressure chamber should drop sufficiently due to the stationary state that occurs between the liquid flowing in via the compensation opening and the liquid flowing out of the back pressure chamber via the control channels. For this purpose, the majority of control channels can be larger or have a larger diameter than the compensation holes. By using a plurality of diaphragm valves, different jet types can be set without complex mechanics. In addition, the control for setting the different jet types can be arranged away from the shower head in a location where it is easily accessible by a user. The individual control channels do not lead back into the shower head downstream of the control valves, but open into at least one inlet upstream of the shower head. This means that fewer interfaces for returning the liquid are required on the shower head because the liquid can be returned to the shower head via at least one inlet.
Die Steuerkanäle können mit einer Ansaugvorrichtung des zumindest einen Zulaufs verbunden sein. Mittels der Ansaugvorrichtung ist die Flüssigkeit insbesondere aus den Steuerkanälen bzw. den Gegendruckkammern der Membranventile ansaugbar, wenn die entsprechenden Steuerventile geöffnet sind.The control channels can be connected to a suction device of the at least one inlet. By means of the suction device, the liquid is in particular removed from the control channels or the back pressure chambers of the diaphragm valves when the corresponding control valves are open.
Die Ansaugvorrichtung kann eine Wirbelkammer umfassen. Die Wirbelkammer kann insbesondere zylinderförmig ausgebildet sein, wobei der Zulauf tangential in die Wirbelkammer mündet, sodass die in die Wirbelkammer einströmende Flüssigkeit in der Wirbelkammer einen Wirbel bildet. Die Flüssigkeit tritt aus der Wirbelkammer durch eine Austrittsöffnung an einer ersten Stirnfläche der (zylinderförmigen) Wirbelkammer aus. Die Steuerkanäle können über eine Eintrittsöffnung an einer zweiten Stirnfläche der Wirbelkammer mit der Wirbelkammer verbunden sein. Die Eintrittsöffnung weist insbesondere einen Durchmesser auf, der kleiner ist als ein Durchmesser der Austrittsöffnung an der gegenüberliegenden ersten Stirnfläche der Wirbelkammer. Durch den Unterdruck im Zentrum des Wirbels wird die Flüssigkeit aus den Steuerkanälen durch die Eintrittsöffnung in die Wirbelkammer angesaugt und verlässt die Wirbelkammer mit der Flüssigkeit aus dem Zulauf durch die Austrittsöffnung. Der Zulauf erstreckt sich von der Austrittsöffnung weiter bis zu dem Brausekopf.The suction device can comprise a vortex chamber. The vortex chamber can in particular be cylindrical, with the inlet opening tangentially into the vortex chamber, so that the liquid flowing into the vortex chamber forms a vortex in the vortex chamber. The liquid exits the vortex chamber through an outlet opening on a first end face of the (cylindrical) vortex chamber. The control channels can be connected to the vortex chamber via an inlet opening on a second end face of the vortex chamber. The inlet opening in particular has a diameter that is smaller than a diameter of the outlet opening on the opposite first end face of the vortex chamber. Due to the negative pressure in the center of the vortex, the liquid from the control channels is sucked into the vortex chamber through the inlet opening and leaves the vortex chamber with the liquid from the inlet through the outlet opening. The inlet extends from the outlet opening to the shower head.
Die Ansaugvorrichtung kann eine Venturi-Düse umfassen. Die Venturi-Düse kann insbesondere nach Art einer Wasserstrahlpumpe ausgebildet sein. Hierzu kann sich insbesondere ein Querschnitt des zumindest einen Zulaufs im Bereich der Ansaugvorrichtung verengen, wobei die Steuerkanäle in den Bereich mit verminderten Querschnitt münden. Die Geschwindigkeit der durch die Ansaugvorrichtung strömenden Flüssigkeit steigt in dem Bereich mit dem verminderten Querschnitt an, wodurch der (statische) Druck in den Steuerkanälen sinkt, sodass die Flüssigkeit aus den Steuerkanälen in die Ansaugvorrichtung gesaugt wird.The suction device can comprise a Venturi nozzle. The Venturi nozzle can in particular be designed in the manner of a water jet pump. For this purpose, a cross-section of the at least one inlet can in particular narrow in the area of the suction device, with the control channels opening into the area with the reduced cross-section. The speed of the liquid flowing through the suction device increases in the area with the reduced cross-section, whereby the (static) pressure in the control channels drops, so that the liquid is sucked from the control channels into the suction device.
Die Ansaugvorrichtung kann außerhalb des Brausekopfs angeordnet sein. Insbesondere kann die Ansaugvorrichtung beispielsweise in einer Wand angeordnet sein, an der die Sanitärarmatur und/oder der Brausekopf befestigt sind.The suction device can be arranged outside the shower head. In particular, the suction device can be arranged, for example, in a wall to which the sanitary fitting and/or the shower head are attached.
Die Mehrzahl von Membranventilen sind in dem Brausekopf angeordnet. Hierzu ist die Mehrzahl von Membranventile insbesondere innerhalb eines Gehäuses des Brausekopfs angeordnet und/oder mithilfe von Komponenten des Brausekopfs ausgebildet.The majority of diaphragm valves are arranged in the shower head. For this purpose, the majority of diaphragm valves are arranged in particular within a housing of the shower head and/or formed using components of the shower head.
Die Steuerventile können außerhalb des Brausekopfs angeordnet sein. Insbesondere können die Steuerventile in einer Wand angeordnet sein, an der die Sanitärarmatur und/oder der Brausekopf befestigt sind. Die Steuerventile können zudem insbesondere in einem Bereich angeordnet sein, in dem diese durch den Benutzer der Sanitärarmatur komfortabel betätigbar sind. Die Mehrzahl von Steuerkanäle können in einem gemeinsamen Rückführkanal münden. In diesem Fall münden die Steuerkanäle über den gemeinsamen Rückführkanal in den zumindest einen Zulauf.The control valves can be arranged outside the shower head. In particular, the control valves can be arranged in a wall to which the sanitary fitting and/or the shower head are attached. The control valves can also be arranged in an area in which they can be easily operated by the user of the sanitary fitting. The plurality of control channels can open into a common return channel. In this case, the control channels open into the at least one inlet via the common return channel.
Die Abläufe können jeweils mit einem Strahlbildner des Brausekopfs verbunden sein. Hierzu können in dem Brausekopf Flüssigkeitskanäle ausgebildet sein, die die Abläufe der einzelnen Membranventile mit den jeweiligen Strahlbildnern verbinden.The outlets can each be connected to a jet former on the shower head. For this purpose, fluid channels can be formed in the shower head that connect the outlets of the individual diaphragm valves with the respective jet formers.

Die Flüssigkeit strömt anschließend von der ersten Zulaufkammer 4 durch eine Ausgleichsbohrung 25 in einer Membran 7 in eine Gegendruckkammer 11. Die Gegendruckkammer 11 befindet sich auf einer der Zulaufkammer 24 gegenüberliegenden Seite der Membran 7. Die Membran 7 ist hier in einem geschlossenen Zustand gezeigt. Im geschlossenen Zustand der Membran 7 herrscht in der Zulaufkammer 24 und der Gegendruckkammer 11 der gleiche Flüssigkeitsdruck. Da die Membran 7 die Gegendruckkammer 11 mit einer größeren Fläche begrenzt als die Zulaufkammer 24, ist die aus dem Flüssigkeitsdruck der Flüssigkeit in der Gegendruckkammer 11 resultierende Kraft auf die Membran 7 größer als die aus dem Flüssigkeitsdruck der Flüssigkeit in der Zulaufkammer 24 resultierende Kraft. Hierdurch wird die Membran 7 auf einen ringförmigen Ventilsitz 26 gedrückt. Der Ventilsitz 26 ist an einem längsseitigen Ende eines ersten Ablaufs 8 ausgebildet.The liquid then flows from the
Die Membranventile 4, 5, 6 sind durch eine Steuerung 12 steuerbar. Die Steuerung 12 umfasst einen ersten Steuerkanal 13 mit einem ersten Steuerventil 16, einem zweiten Steuerkanal 14 mit einem zweiten Steuerventil 17 und einem dritten Steuerkanal 15 mit einem dritten Steuerventil 18. Die Steuerkanäle 13, 14, 15 weisen jeweils nur eine einzige Schnittstelle 27 zum Brausekopf 2 auf und münden in einem gemeinsamen Rückführkanal 20. Im geöffneten Zustand des ersten Steuerventils 16 fließt die Flüssigkeit aus der Gegendruckkammer 11 über den ersten Steuerkanal 16 und den Rückführkanal 20 zu einer Ansaugvorrichtung 19, die in dem Zulauf 3 angeordnet ist. Die Ansaugvorrichtung 19 saugt die Flüssigkeit aus der Gegendruckkammer 11 zurück in den Zulauf 3, über den die Flüssigkeit den Membranventilen 4, 5, 6 wieder zuführbar ist. Durch das Abfließen der Flüssigkeit aus der Gegendruckkammer 11 sinkt der Flüssigkeitsdruck in der Gegendruckkammer 11, sodass die Membran 7 von dem Ventilsitz 26 abgehoben wird. D. h. die Membran 7 bewegt sich in der
