Description

Die vorliegende Erfindung betrifft eine Umschaltvorrichtung für eine Sanitärarmatur, mit einem Einlass und mindestens zwei jeweils in Fluidverbindung mit dem Einlass bringbaren Auslässen, sowie eine Brause, die eine solche Umschaltvorrichtung umfasst.The present invention relates to a switching device for a sanitary fitting, with an inlet and at least two outlets that can each be brought into fluid connection with the inlet, as well as a shower which comprises such a switching device.

Eine Brause mit einer Umschaltvorrichtung ist beispielsweise aus CN 204544502 U bekannt, wobei die Umschaltvorrichtung ein drehbar gelagertes Ventilelement umfasst, welches in unterschiedlichen Drehstellungen eine Fluidverbindung zwischen einem Einlass und jeweils einer Gruppe von Austrittsöffnungen freigibt und die Fluidverbindung zu anderen Austrittsöffnungen blockiert. Bei dieser Brause muss eine Bedienung eines Betätigungselements also in eine Drehbewegung des Ventilelements umgesetzt werden.A shower with a switching device is off, for example CN 204 544 502 U known, wherein the switching device comprises a rotatably mounted valve element which, in different rotational positions, releases a fluid connection between an inlet and a respective group of outlet openings and blocks the fluid connection to other outlet openings. In this shower, operation of an actuating element must therefore be converted into a rotary movement of the valve element.

Aufgabe der vorliegenden Erfindung ist es daher, eine Umschaltvorrichtung für eine Sanitärarmatur anzugeben, die auf einem anderen Betätigungsmechanismus beruht.The object of the present invention is therefore to specify a switching device for a sanitary fitting which is based on a different actuating 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 given in the dependent claims and in the description, individual features of the advantageous developments can be combined with one another in a technologically sensible manner.

Gelöst wird die Aufgabe insbesondere durch eine Umschaltvorrichtung für eine Sanitärarmatur nach den Ansprüchen 1 und 2.The object is achieved in particular by a switching device for a sanitary fitting according to Claims 1 and 2.

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. Bevorzugt weist die Umschaltvorrichtung mehr als zwei Auslässe auf. Bevorzugt weist die Umschaltvorrichtung genau drei oder vier Auslässe auf. 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.In its basic concept, the invention thus provides in particular that the linearly movably mounted closing elements can each be moved between their closed position and open position in that an elevation of the switching element moves the respective closing element against its bias. The arrangement of the elevation on the switching element and the arrangement of the switching element on the switching device can therefore specify in which switching positions certain outlets are connected to the inlet and in which they are not. In each switching position, one outlet or several outlets can be connected to the inlet. The switching device preferably has more than two outlets. The switching device preferably has exactly three or four outlets. The closing elements are preferably in their closed positions when they are in their pretensioned position and out of contact with an elevation. However, it can also be provided that at least one closing element is in the closed position when it is in contact with an elevation and in a position displaced against the bias.

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.The closing elements in particular have a closing area which, in the closed position, blocks a flow opening between the inlet and the corresponding outlet. The extension protrudes from this closing area and is in contact with an elevation in at least one switching position of the switching element.

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 in a linearly movable manner parallel to one another. The closing elements therefore 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 oriented transversely to the closing direction of the closing elements, the in particular precisely one switching element is preferably rotatably, pivotably or linearly movably supported. In this level, the switching element can in particular be brought into such a number of different switching positions that corresponds to the number of outlets, so that the fluid connection from the inlet to precisely one outlet is preferably released in each switching position. In addition, further switching positions can be provided so that the fluid connection to two or more outlets is released in at least one of these further switching positions.

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 implementation of the invention it would be sufficient if the switching element has exactly one protruding elevation. However, it can also be provided that a number of elevations corresponding to the number of outlets is formed on the switching element.

Erfindungsgemäß sind Offnungen 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.According to the invention, openings of the outlets are arranged in an outlet plane and all closing elements are arranged so as to be linearly movable in a closing plane, the outlet plane and the closing plane being 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, one outlet channel leads from an inlet chamber assigned to the inlet to each outlet, one being formed in the transition area between inlet chamber and 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 closure elements are each passed 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, therefore, several outlet channels go to the outlets, the closing element seat being released in the open position of the respective closing element. The closing element seat thus laterally limits a flow into the outlet channel. In the closed position, a closing area of the closing element is pressed onto the closing element seat in such a way that the flow cross section delimited 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.If a preload can be generated with suitable means, it is preferred that the preload is generated by means of a spring which preloads 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.The inlet chamber and the outlet channels are preferably formed in a one-piece housing body which is closed on the one hand by a housing cover, which thus in particular delimits the inlet chamber or the outlet channels, and on which the switching element is movably mounted on the other hand. 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 beginning is also achieved by a shower with a shower head and a jet disk, which has at least two separately controllable groups of outlet openings, as well as with a switching device according to the invention for switching between the two groups of outlet openings, with each outlet of the switching device having a group of outlet openings assigned. In particular, result in the spray disc or a further element of the shower head Connection channels each to a group of outlet openings, one outlet of the switching device being assigned to a connection channel.

Die in den Figuren 1 bis 4 dargestellte Umschaltvorrichtung 1 umfasst einen Gehäusegrundkörper 15 sowie einen in den Figuren 1 und 2 nicht gezeigten Gehäusedeckel 16.The ones in the Figures 1 to 4 Switching device 1 shown comprises a housing base body 15 and one in the Figures 1 and 2 Housing cover 16, not shown.

An dem Gehäusegrundkörper 15 ist ein Schaltelement 4 linear verschieblich gelagert. Wie aus Figur 4 hervorgeht, weist das Schaltelement 4 drei in Richtung des Gehäusegrundkörpers 15 vorspringende Erhebungen 8 auf.A switching element 4 is mounted so as to be linearly displaceable on the housing base body 15. How out Figure 4 As can be seen, the switching element 4 has three elevations 8 projecting in the direction of the housing base body 15.

Der Gehäusegrundkörper 15 weist einen Einlass 2 und drei Auslässe 3 auf, wobei die Öffnungen 9 der Auslässe 3 in einer Ebene angeordnet sind, die zu einer Ebene der Einlassöffnung des Einlasses 2 orthogonal ist. Wie insbesondere aus der Schnittdarstellung der Figur 4 hervorgeht, sind in dem Gehäusegrundkörper 15 drei Auslasskanäle 11 ausgebildet, die jeweils zu einem Auslass 3 führen. Zudem begrenzt der Gehäusegrundkörper 15 gemeinsam mit dem Gehäusedeckel 16 eine Einlasskammer 10, wobei in dem Übergangsbereich von der Einlasskammer 10 in jeden Auslasskanal 11 ein Schließelementsitz 12 ausgebildet ist.The housing base body 15 has an inlet 2 and three outlets 3, the openings 9 of the outlets 3 being arranged in a plane which is orthogonal to a plane of the inlet opening of the inlet 2. As in particular from the sectional view of Figure 4 As can be seen, three outlet channels 11 are formed in the housing base body 15, each of which leads to an outlet 3 lead. In addition, the housing base body 15, together with the housing cover 16, delimits an inlet chamber 10, a closing element seat 12 being formed in the transition region from the inlet chamber 10 into each outlet channel 11.

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 comprises a closing element 5 for each outlet 3. As can be seen in particular from the sectional illustration of FIG Figure 4 As can be seen, each closing element 5 is mounted in the switching device 1 so as to be linearly movable. Each closing element 5 has a closing area 21 and an extension 7 extending from the closing area 21 through a respective passage channel 11. The extension 7 emerges 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. Each closing element 5 is also linearly guided in the housing cover 16 and is pretensioned with respect to the cover 16 by means of a spring 14. The closing elements 5 are therefore mounted so as to be 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 into their closed position by means of the springs 14. In the Figure 4 Closing elements 5 arranged on the left and right are in their closed position, in which the closing area 21 presses the sealing element 22 onto 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 closing elements 5 arranged on the left and right in the FIG Figure 4 The switching position shown with its 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 Figure 4 In contrast, the closing element 5 arranged in the center is with its extension 7 in contact with the elevation 8a of the switching element 4. As a result, the middle closing element 5 is moved against its bias and thus the closing area 21 is lifted from the closing element seat 12 so that a fluid connection from the inlet 2 to the central 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.If the switching element 4 would now be from the in Figure 4 If the position shown is shifted linearly to the left, the extension 7 of the central closing element 5 would no longer be in contact with the elevation 8a of the switching element 4. At the same time, however, the right closing element 5 with its extension 7 would come into contact with the elevation 8b of the switching element 4, whereby the right closing element 5 would be moved from its closed position 21 into its open position against the spring bias.

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 is shown in FIG Figure 5 is shown. The shower 17 has a jet disk 20 with several groups of outlet openings 19. Each group of outlet openings 19 is connected to an outlet 3 of the switching device 1 via a respective connecting channel 18. Depending on the switching position, a group of the outlet openings 19 is brought into fluid connection with the water supply connected to the inlet 2 of the switching device 1.
