Aufgabe der vorliegenden Erfindung ist es daher, eine Umschaltvorrichtung für eine Sanitärarmatur anzugeben, die auf einem anderen Betätigungsmechanismus beruht.Object of the present invention is therefore to provide a switching device for a sanitary fitting, which is based on a different actuation mechanism.

Gelöst wird die Aufgabe durch eine Umschaltvorrichtung mit den Merkmalen des unabhängigen Anspruchs sowie durch eine Brause mit einer erfindungsgemäßen Umschaltvorrichtung. Vorteilhafte Weiterbildungen der Umschaltvorrichtung sind in den abhängigen Ansprüchen und in der Beschreibung angegeben, wobei einzelne Merkmale der vorteilhaften Weiterbildungen in technologisch sinnvoller Weise beliebig miteinander kombinierbar sind.The object is achieved by a switching device with the features of the independent claim and by a shower with a switching device according to the invention. Advantageous developments of the switching device are specified in the dependent claims and in the description, wherein individual features of the advantageous developments in a technologically meaningful way can be combined with each other.

Gelöst wird die Aufgabe insbesondere durch eine Umschaltvorrichtung für eine Sanitärarmatur, mit einem Einlass und mindestens zwei jeweils in Fluidverbindung mit dem Einlass bringbaren Auslässen, wobei die Umschaltvorrichtung ein Schaltelement und für jeden Auslass jeweils ein Schließelement umfasst, wobei jedes Schließelement

  • in seiner Schließstellung die Fluidverbindung zu dem zugeordneten Auslass blockiert und in seiner Offenstellung die Fluidverbindung zu dem Auslass freigibt,
  • zwischen seiner Schließstellung und seiner Offenstellung in einer Schließrichtung linear beweglich gelagert ist,
  • in Richtung der Schließstellung oder der Offenstellung vorgespannt ist und
  • einen Fortsatz aufweist, welcher in Richtung des Schaltelements vorsteht, und wobei das Schaltelement
  • in einer quer zu der Schließrichtung der Schließelemente ausgerichteten Ebene beweglich gelagert ist,
  • in wenigstens zwei unterschiedliche Schaltstellungen in der Ebene bewegbar ist und
  • mindestens eine in Richtung der Schließelemente vorspringende Erhebung aufweist,
so dass jedes Schließelement jeweils in zumindest einer Schaltstellung des Schaltelements mit seinem Fortsatz außer Anlage mit einer Erhebung des Schaltelements ist und während der Bewegung des Schaltelements in zumindest eine andere Schaltstellung mit seinem Fortsatz in Kontakt mit einer Erhebung des Schaltelements kommt, wodurch das Schließelement durch Überführen des Schaltelements aus der einen Schaltstellung in die andere Schaltstellung gegen seine Vorspannung zwischen seiner Offenstellung und seiner Schließstellung bewegbar ist.The object is achieved, in particular, by a switching device for a sanitary fitting, having an inlet and at least two outlets which can be brought into fluid connection with the inlet, the switching device comprising a switching element and, for each outlet, a closing element, each closing element
  • blocked in its closed position the fluid connection to the associated outlet and releases the fluid connection to the outlet in its open position,
  • is mounted linearly movable between its closed position and its open position in a closing direction,
  • is biased in the direction of the closed position or the open position and
  • a projection which projects in the direction of the switching element, and wherein the switching element
  • is movably mounted in a plane aligned transversely to the closing direction of the closing elements,
  • is movable in at least two different switching positions in the plane and
  • has at least one protruding in the direction of the closing elements survey,
so that each closing element is in each case in at least one switching position of the switching element with its extension out of engagement with a collection of the switching element and comes during the movement of the switching element in at least one other switching position with its extension in contact with a collection of the switching element, whereby the closing element by transferring of the switching element from the one switching position to the other switching position is movable against its bias between its open position and its closed position.

Die Erfindung sieht in ihrem Grundgedanken also insbesondere vor, dass die linear beweglich gelagerten Schließelemente jeweils dadurch zwischen ihrer Schließstellung und Offenstellung bewegt werden können, dass eine Erhebung des Schaltelements das jeweilige Schließelement gegen seine Vorspannung bewegt. Durch die Anordnung der Erhebung an dem Schaltelement und durch die Anordnung des Schaltelements an der Umschaltvorrichtung kann also vorgegeben werden, in welchen Schaltstellungen bestimmte Auslässe mit dem Einlass verbunden werden und in welchen nicht. In jeder Schaltstellung können also ein Auslass oder mehrere Auslässe mit dem Einlass verbunden sein.The invention thus provides in its basic idea in particular that the linearly movably mounted closing elements can each be moved between their closed position and open position, that a survey of the switching element moves the respective closing element against its bias. Due to the arrangement of the survey on the switching element and by the arrangement of the switching element on the switching device can therefore be specified in which switching positions certain outlets are connected to the inlet and in which not. In each switching position, therefore, one or more outlets can be connected to the inlet.

Bevorzugt weist die Umschaltvorrichtung mehr als zwei Auslässe auf. Bevorzugt weist die Umschaltvorrichtung genau drei oder vier Auslässe auf.Preferably, the switching device has more than two outlets. Preferably, the switching device has exactly three or four outlets.

Bevorzugt befinden sich die Schließelemente in ihren Schließstellungen, wenn sie sich in ihrer vorgespannten Stellung und außer Anlage mit einer Erhebung befinden. Es kann aber auch vorgesehen sein, dass sich mindestens ein Schließelement bei Anlage mit einer Erhebung und in einer gegen die Vorspannung verschobenen Stellung in der Schließstellung befindet.Preferably, the closure elements are in their closed positions when they are in their biased position and out of engagement with a survey. But it can also be provided that at least one closing element is in contact with a survey and in a shifted against the bias position in the closed position.

Die Schließelemente weisen insbesondere einen Schließbereich auf, welcher in der Schließstellung eine Strömungsöffnung zwischen dem Einlass und dem entsprechenden Auslass blockiert. Von diesem Schließbereich steht der Fortsatz vor, welcher in zumindest einer Schaltstellung des Schaltelements in Anlage mit einer Erhebung ist.In particular, the closing elements have a closing region which, in the closed position, blocks a flow opening between the inlet and the corresponding outlet. From this closing area is the extension, which is in at least one switching position of the switching element in contact with a survey.

Die Schließelemente sind bevorzugt alle parallel zueinander jeweils linear beweglich gelagert. Die Schließelemente weisen also alle die gleiche Schließrichtung auf.The closing elements are preferably all mounted parallel to each other linearly movable. The closing elements thus all have the same closing direction.

In einer quer zu der Schließrichtung der Schließelemente ausgerichteten Ebene ist das insbesondere genau eine Schaltelement bevorzugt drehbar, schwenkbar oder linear beweglich gelagert. In dieser Ebene kann das Schaltelement insbesondere in eine solche Anzahl von unterschiedlichen Schaltstellungen gebracht werden, die der Anzahl der Auslässe entspricht, sodass bevorzugt in jeder Schaltstellung die Fluidverbindung von dem Einlass zu genau einem Auslass freigegeben ist. Darüber hinaus können weitere Schaltstellungen vorgesehen sein, sodass in zumindest einer dieser weiteren Schaltstellungen die Fluidverbindung zu zwei oder mehr Auslässen freigegeben ist.In a plane aligned transversely to the closing direction of the closing elements, in particular, exactly one switching element is preferably rotatable, pivotable or linearly movable. In this plane, the switching element can be brought in particular in such a number of different switching positions, which corresponds to the number of outlets, so that preferably in each switching position, the fluid connection is released from the inlet to exactly one outlet. In addition, further switching positions may be provided, so that in at least one of these other switching positions, the fluid connection is released to two or more outlets.

Für die Realisierung der Erfindung wäre es ausreichend, wenn das Schaltelement genau eine vorspringende Erhebung aufweist. Es kann aber auch vorgesehen sein, dass eine der Anzahl der Auslässe entsprechende Anzahl von Erhebungen an dem Schaltelement ausgebildet ist.For the realization of the invention, it would be sufficient if the switching element has exactly one projecting survey. However, it can also be provided that a number of outlets corresponding number of elevations is formed on the switching element.

In einer bevorzugten Ausführungsform sind Öffnungen der Auslässe in einer Auslassebene angeordnet und alle Schließelemente linear beweglich in einer Schließebene angeordnet, wobei die Auslassebene und die Schließebene parallel zueinander versetzt angeordnet sind. Dies bedeutet also, dass die Schließelemente quer zu einer Strömungsrichtung angeordnet sind, in welcher das Fluid durch die Öffnungen der Auslässe austritt. Auf diese Weise kann eine besonders flache Bauform der Umschaltvorrichtung erreicht werden.In a preferred embodiment, openings of the outlets are arranged in an outlet plane and all closing elements are arranged to be linearly movable in a closing plane, wherein the outlet plane and the closing plane are arranged offset parallel to one another. This means that the closing elements are arranged transversely to a flow direction in which the fluid exits through the openings of the outlets. In this way, a particularly flat design of the switching device can be achieved.

In einer weiteren Ausführungsform führt von einer dem Einlass zugeordneten Einlasskammer jeweils ein Auslasskanal zu jedem Auslass, wobei ein jeweils im Übergangsbereich von Einlasskammer und Auslasskanal ausgebildeter Schließelementsitz von dem jeweiligen Schließelement in seiner Schließstellung verschlossen wird. In diesem Zusammenhang ist insbesondere bevorzugt, wenn die Schließelemente jeweils mit ihren Fortsätzen durch den jeweiligen Auslasskanal hindurchgeführt sind und in einer Abdichtung am Ende des Auslasskanals aus dem Auslasskanal hinausgeführt sind. Von der gemeinsamen Einlasskammer gehen also mehrere Auslasskanäle zu den Auslässen, wobei in der Öffnungsstellung des jeweiligen Schließelements der Schließelementsitz freigegeben ist. Der Schließelementsitz begrenzt also eine Strömung in den Auslasskanal seitlich. In der Schließstellung wird ein Schließbereich des Schließelements auf den Schließelementsitz so gedrückt, dass der von dem Schließelementsitz begrenzte Strömungsquerschnitt verschlossen ist.In a further embodiment, an inlet channel assigned to the inlet leads in each case to an outlet channel to each outlet, wherein one each formed in the transition region of the inlet chamber and the outlet channel Closing element seat is closed by the respective closing element in its closed position. In this context, it is particularly preferred if the closing elements are respectively guided with their extensions through the respective outlet channel and are led out of the outlet channel in a seal at the end of the outlet channel. From the common inlet chamber so go a plurality of outlet channels to the outlets, being released in the open position of the respective closing element of the closing element seat. The closing element seat thus limits a flow in the outlet channel laterally. In the closed position, a closing region of the closing element is pressed onto the closing element seat in such a way that the flow cross section bounded by the closing element seat is closed.

Soweit eine Vorspannung mit geeigneten Mitteln erzeugt werden kann, ist es bevorzugt, dass die Vorspannung mittels einer Feder erzeugt wird, die das Schließelement in Richtung des Schließelementsitzes vorspannt.As far as a bias voltage can be generated by suitable means, it is preferred that the bias voltage is generated by means of a spring which biases the closing element in the direction of the closing element seat.

Bevorzugt sind die Einlasskammer und die Auslasskanäle in einem einteiligen Gehäusegrundkörper ausgebildet, der einerseits von einem Gehäusedeckel verschlossen ist, der somit insbesondere die Einlasskammer oder die Auslasskanäle begrenzt, und an dem andererseits das Schaltelement bewegbar gelagert ist. In diesem Zusammenhang ist insbesondere bevorzugt, dass sich die Federn an dem Gehäusedeckel abstützen.Preferably, the inlet chamber and the outlet channels are formed in a one-piece housing base body, which is closed on the one hand by a housing cover, which thus limits in particular the inlet chamber or the outlet channels, and on the other hand, the switching element is movably mounted. In this context, it is particularly preferred that the springs are supported on the housing cover.

Gelöst wird die eingangs formulierte Aufgabe auch durch eine Brause mit einem Brausekopf und einer Strahlscheibe, die mindestens zwei getrennt ansteuerbare Gruppen von Austrittsöffnungen aufweist, sowie mit einer erfindungsgemäßen Umschaltvorrichtung zum Umschalten zwischen den beiden Gruppen von Austrittsöffnungen, wobei jedem Auslass der Umschaltvorrichtung eine Gruppe der Austrittsöffnungen zugeordnet ist. Insbesondere führen also in der Strahlscheibe oder einem weiteren Element der Brause ausgebildete Verbindungskanäle jeweils zu einer Gruppe von Austrittsöffnungen, wobei ein Auslass der Umschaltvorrichtung jeweils einem Verbindungskanal zugeordnet ist.The object formulated at the outset is also achieved by a shower head with a shower head and a jet disc, which has at least two separately controllable groups of outlet openings, and with a switching device according to the invention for switching between the two groups of outlet openings, wherein each outlet of the switching device has a group of the outlet openings assigned. In particular, therefore, trained in the jet disk or another element of the shower Connecting channels in each case to a group of outlet openings, wherein an outlet of the switching device is assigned in each case a connecting channel.

As in particular from the sectional view of FIG. 4 it can be seen, 15 three outlet channels 11 are formed in the housing base body, each to an outlet 3 lead. In addition, the housing base body 15 defines together with the housing cover 16 an inlet chamber 10, wherein in the transition region from the inlet chamber 10 into each outlet channel 11, a closing element seat 12 is formed.

Die Umschaltvorrichtung 1 umfasst zudem für jeden Auslass 3 ein Schließelement 5. Wie insbesondere aus der Schnittdarstellung der Figur 4 hervorgeht, ist jedes Schließelement 5 linear beweglich in der Umschaltvorrichtung 1 gelagert. Jedes Schließelement 5 weist einen Schließbereich 21 und einen sich von dem Schließbereich 21 durch jeweils einen Durchlasskanal 11 hindurch erstreckenden Fortsatz 7 auf. Der Fortsatz 7 tritt am Ende des Auslasskanals 11 durch eine Abdichtung 13 durch den Gehäusegrundkörper 15 in Richtung des Schaltelements 4 hinaus. Jedes Schließelement 5 ist zudem in dem Gehäusedeckel 16 linear geführt und gegenüber dem Deckel 16 mittels einer Feder 14 vorgespannt. Die Schließelemente 5 sind also in einer Schließrichtung 6 linear beweglich gelagert.The switching device 1 also includes for each outlet 3, a closing element 5. As in particular from the sectional view of FIG. 4 shows, each closing element 5 is mounted linearly movable in the switching device 1. Each closing element 5 has a closing region 21 and an extension 7 extending from the closing region 21 through a respective passage 11. The extension 7 occurs at the end of the outlet channel 11 through a seal 13 through the housing base body 15 in the direction of the switching element 4 addition. Each closing element 5 is also linearly guided in the housing cover 16 and biased relative to the cover 16 by means of a spring 14. The closing elements 5 are thus mounted linearly movable in a closing direction 6.

Die Schließelemente 5 sind mittels der Federn 14 jeweils in ihre Schließstellung vorgespannt. Die in Figur 4 links und rechts angeordneten Schließelemente 5 befinden sich in ihrer Schließstellung, in welcher der Schließbereich 21 das Dichtelement 22 auf den jeweiligen Schließelementsitz 12 drückt. In dieser Schließstellung ist die Fluidverbindung von dem Einlass 2 zu dem jeweiligen Auslass 3 blockiert. Es ist zu erkennen, dass die links und rechts angeordneten Schließelemente 5 in der in Figur 4 dargestellten Schaltstellung mit ihren Fortsätzen 7 nicht in Anlage mit einer der Erhebungen 8 des Schaltelementes 4 sind.The closing elements 5 are each biased by the springs 14 in their closed position. In the FIG. 4 Left and right arranged closing elements 5 are in their closed position, in which the closing portion 21, the sealing element 22 presses on the respective closing element seat 12. In this closed position, the fluid connection from the inlet 2 to the respective outlet 3 is blocked. It can be seen that the left and right arranged closing elements 5 in the in FIG. 4 shown switching position with their extensions 7 are not in contact with one of the elevations 8 of the switching element 4.

Das in der Figur 4 in der Mitte angeordnete Schließelement 5 ist hingegen mit seinem Fortsatz 7 in Anlage mit der Erhebung 8a des Schaltelements 4. Hierdurch ist das mittlere Schließelement 5 entgegen seiner Vorspannung bewegt und somit ist der Schließbereich 21 von dem Schließelementsitz 12 abgehoben, sodass eine Fluidverbindung von dem Einlass 2 zu dem mittleren Auslass 3 freigegeben ist.That in the FIG. 4 in the middle arranged closing element 5, however, with its extension 7 in abutment with the elevation 8a of the switching element 4. As a result, the middle closing element 5 is moved counter to its bias and thus, the closing portion 21 is lifted from the closing member seat 12 so that fluid communication from the inlet 2 to the middle outlet 3 is released.

Würde nun das Schaltelement 4 von der in Figur 4 dargestellten Stellung linear nach links verschoben, so würde sich der Fortsatz 7 des mittleren Schließelements 5 nicht mehr in Anlage mit der Erhebung 8a des Schaltelements 4 befinden. Gleichzeitig würde jedoch das rechte Schließelement 5 mit seinem Fortsatz 7 in Anlage mit der Erhebung 8b des Schaltelements 4 gelangen, wodurch das rechte Schließelement 5 entgegen der Federvorspannung aus seiner Schließstellung 21 in seine Offenstellung bewegt würde.Would now the switching element 4 of the in FIG. 4 Position shown shifted linearly to the left, the extension 7 of the central closing element 5 would no longer be in contact with the elevation 8 a of the switching element 4. At the same time, however, the right-hand closing element 5 with its extension 7 would come into contact with the elevation 8b of the switching element 4, whereby the right-hand closing element 5 would be moved out of its closed position 21 into its open position against the spring preload.

Die Umschaltvorrichtung 1 wird insbesondere in einer Brause 17 eingesetzt, welche in Figur 5 dargestellt ist. Die Brause 17 weist eine Strahlscheibe 20 mit mehreren Gruppen von Austrittsöffnungen 19 auf. Jede Gruppe von Austrittsöffnungen 19 ist über jeweils einen Verbindungskanal 18 mit einem Auslass 3 der Umschaltvorrichtung 1 verbunden. Je nach Schaltstellung wird also eine Gruppe der Austrittsöffnungen 19 mit der an den Einlass 2 der Umschaltvorrichtung 1 angeschlossenen Wasserversorgung in Fluidverbindung gebracht.The switching device 1 is used in particular in a shower 17, which in FIG. 5 is shown. The showerhead 17 has a jet disk 20 with a plurality of groups of outlet openings 19. Each group of outlet openings 19 is connected in each case via a connecting channel 18 to an outlet 3 of the switching device 1. Depending on the switching position, therefore, a group of the outlet openings 19 is brought into fluid communication with the water supply connected to the inlet 2 of the switching device 1.
