    The invention relates to an actuating device for a valve of a sanitary installation, in particular for a drain valve of a cistern, with a cover plate and with an operating element for triggering at least one valve function, in particular a flushing process, wherein the operating element is rotatably mounted relative to the cover plate.
    Actuating devices for valves of sanitary installations are known in various designs. These actuation devices include, in particular, actuation plates for toilets and / or urinals for triggering a flushing water flow and fittings for setting a water temperature and a water volume flow.
    Devices are also already known in the prior art which have a light source connected to a power source, which is used to illuminate the actuating device or the surroundings of the actuating device.
    From DE 20 2008 005 518 U1 an actuator plate for sanitary installations, in particular for a concealed cistern, is known which has light outlet openings and at least one lamp is arranged on the back. A power supply unit or a battery arranged on the rear of the actuating plate serves as the power source for the light source. To trigger a flow of flushing water, the actuating plate has at least one pushbutton. The light exit openings are formed in the actuating plate itself and / or in the push button.
    Furthermore, mechanical actuating devices for toilet cisterns are known which have a base plate which can be mounted as a cover on an inspection opening of the cistern and on which an actuating element in the form of a handle is rotatably mounted. Such an actuating device described in EP 1 353 013 A2 has two translationally movable transmission elements which act directly or by means of further interposed transmission elements on a drain valve of the cistern. For this purpose, the actuating device has an adapter which is designed in such a way that it converts the rotary movement of the handle into a translational movement and, depending on the direction of rotation of the handle, acts optionally on one of the two transmission elements which are used to trigger two different amounts of flush water. The structural design of this mechanical actuating device is relatively complex, the mechanics requiring a relatively large amount of space.
    Based on this, the present invention seeks to provide an actuating device of the type mentioned, which has a simple, relatively compact mechanism for triggering at least one valve function, is equally suitable for actuating various valves, in particular various drain valves, and is characterized by an easily recognizable control element.
    According to the invention, this object is achieved by an actuating device having the features specified in claim 1. Preferred and advantageous configurations of the actuating device according to the invention are given in the dependent claims.
    The actuating device according to the invention is characterized in that the rotatable control element has a contact element for electrically triggering the at least one valve function, wherein a light source is arranged in the control element, to which a light guide is assigned, the light emitted by the light source in the direction of the cover plate directs.
    As a result, a rotational movement of the operating element can be converted in a structurally favorable manner into an electrical signal for triggering the at least one valve function. The valve can be assigned an electrical actuator, e.g. an electric motor, an electromagnetic switch or the like, which is operated when the electrical signal is set or output and acts on the valve via at least one force transmission element, for example a Bowden cable.
    The actuating device is preferably an actuating plate for a toilet or a urinal. Due to the rotatable mounting of the operating element, the actuating device can be adapted to design specifications that exclude the use of conventional push buttons. Thanks to the conversion of the mechanical rotary movement into an electrical signal, an electrically operated actuator can be used to trigger the valve function. The actuator can be placed in many places, for example directly on the cover plate, but also directly on the housing of the valve or at another place on or within a toilet or urinal cistern. A rotatable operating element can thus be combined in a structurally simple manner with already existing trigger mechanisms for valves, in particular with various drain valves of sanitary cisterns.
    The lighting technology integrated in the control element of the actuating device according to the invention, by means of which light is directed from the control element in the direction of the cover plate, causes the control element to be clearly visible even when it is darkened or in the vicinity of the control element. The lighting is preferably designed as indirect lighting and / or in the manner of so-called ambient lighting. The lighting can thus in particular also act as a design element of the actuating device. Furthermore, the lighting of the device according to the invention can also be used as an orientation light when it gets dark in the relevant building space, e.g. a bathroom.
    The additional benefit of the actuator according to the invention comes into its own when a tired person uses a toilet or bathroom at night and does not want to turn on the main lighting of the bathroom, which is often perceived as annoying when tired. In addition, ambient lighting, especially if it is designed as indirect lighting, is often perceived by users or customers as being visually appealing.
    The lighting technology integrated in the actuating device according to the invention, in particular the light guide, is preferably designed such that the light emitted by the illuminant is distributed largely homogeneously on the cover plate.
    An advantageous embodiment of the actuating device according to the invention is characterized in that the contact element for triggering the at least one valve function is designed as a sliding contact, the cover plate being provided with an electrical circuit board which has at least one electrical contact surface assigned to the contact element. As a result, a rotary movement of the operating element can be converted into an electrical signal for triggering the at least one valve function in a structurally particularly simple and reliable manner. The printed circuit board preferably has at least two electrical contact surfaces assigned to the contact element, which are electrically insulated from one another, the contact element optionally being connectable to one of the contact surfaces in an electrically conductive manner by rotating the operating element. Thus, at least two different valve functions, for example a full flush and a partial flush in a drain valve of a sanitary cistern, can be triggered reliably and comfortably.
    The range of rotation of the control element is preferably limited by two stops, the circuit board having two electrical contact surfaces assigned to the contact element (sliding contact element), which are electrically isolated from one another, and the control element can be rotated so far in one of the two possible directions of rotation until one of the two stops blocks further rotation. Each of the two rotational positions of the operating element defined by the stops is assigned a different one of the two electrical contact surfaces, so that the contact element can optionally be connected to one of the two contact surfaces to form an electrical circuit.
    Another advantageous embodiment of the actuating device according to the invention is characterized in that the rotatable control element is provided with a return means which is designed such that the control element automatically returns to an initial position after manually rotating the same to trigger the at least one valve function and release the control element (Neutral position) is reset.
    A further advantageous embodiment of the invention provides that the lighting means is connected via sliding contacts to the circuit board or a circuit board attached to the cover plate. In this way, a permanent electrical connection between the lighting means and a voltage source can be ensured in a structurally simple and reliable manner. In particular, this configuration is favorable for the manufacture and assembly of the actuating device according to the invention. For example, the sliding contacts assigned to the lighting means can be constructed identically to the sliding contact for triggering the at least one valve function. Such a standardization of components (contact elements) can save manufacturing costs in particular.
    The or the above electrical contact elements (sliding contacts) preferably have a spring element and / or a resilient portion, so that the respective contact element is resiliently biased against the circuit board or the electrical contact surface assigned to the contact element. For example, the electrical contact elements are pin-shaped, each of the contact elements having a sleeve, at the ends of which contact pins protrude axially, which are slidably guided in the sleeve and are resiliently pretensioned in the direction of the respective sleeve end by at least one spring element arranged in the sleeve. At the sleeve ends, stops, e.g. ring caps, are preferably provided, which prevent the contact pins from accidentally falling out of the sleeve.
    The circuit board preferably has contact surfaces which each extend along a predetermined range of rotation (angle of rotation) of the operating element, are electrically isolated from one another and are assigned to the sliding contacts electrically connected to the lighting means. These contact surfaces, which are preferably in permanent contact with the sliding contacts assigned to them, are, for example, essentially arcuate. Such a configuration enables reliable permanent lighting of the actuating device to be implemented without a user having to activate the lighting means arranged in the operating element for this purpose. In particular, a permanent electrical connection between the contact elements (sliding contacts) and the associated contact surfaces can thus be ensured even when the operating element is rotated. Reliable lighting is thus ensured even while the operating element is being used.
    According to a further advantageous embodiment of the invention, the lighting means is assigned a reflector, by means of which light emitted by the lighting means is directed in the direction of the light guide. The light emitted by the illuminant can be deflected, shaped, scattered and / or concentrated by the reflector. In particular, the reflector enables greater degrees of freedom with regard to the arrangement of the illuminant or illuminants in the operating element relative to the light guide. For this purpose, the reflector is preferably designed to be essentially ring-shaped and / or conical. It can be connected to the control element in a rotationally fixed manner. An annular configuration of the reflector enables the electrical contact element or elements to be passed through the recess defined by the annular reflector. This configuration can advantageously contribute to a compact design of the operating element provided with integrated lighting technology components.
    A further advantageous embodiment of the device according to the invention is that the lighting means is formed from one or more light-emitting diodes (LEDs). Light-emitting diodes can be operated with a low voltage of, for example, less than / equal to 25 volts, preferably less than / equal to 12 volts, which is harmless to humans. In addition, light-emitting diodes are characterized by relatively small dimensions and low energy consumption.
    The lighting means arranged in the operating element is preferably formed from a plurality, for example from at least four, five, six or more LEDs. The use of a large number of light-emitting diodes simplifies largely homogeneous light distribution on the cover plate of the actuating device, in particular as ambient lighting for the operating element.
    According to a further embodiment of the invention, the brightness and / or the light color of the illuminant can be adjusted. For example, the lighting means can be formed from light-emitting diodes that can light up in different colors. The user of the actuating device according to the invention thus has the option of adapting the color of the light emitted by the illuminant of the device to his or her individual taste in color.
    A further advantageous embodiment of the invention provides that the color of the lighting of the actuating device according to the invention changes as a function of the direction of rotation or the rotary position of the operating element. For example, the lighting can have a red hue when the control element is rotated clockwise, while it has a yellow or other hue when the control element is rotated counterclockwise.
    With regard to inexpensive prefabrication and simple and quick assembly of the actuating device, it is advantageous if, according to a further embodiment of the invention, the light-emitting diodes are fastened on a common circuit board in the operating element. In this way, a high degree of prefabrication can be achieved, which simplifies the subsequent assembly and saves assembly time. A further advantageous embodiment of the invention is characterized in that the lighting means is assigned a twilight sensor which automatically switches the lighting means on in certain light conditions in the vicinity of the actuating device and switches it off again at a certain brightness. In this way, the power consumption, which is already relatively low when light-emitting diodes are preferably used as lighting means, can be further reduced.
    According to a preferred embodiment, the operating element of the actuating device according to the invention is knob-shaped. The operating element thus has, for example, a spherical or button-shaped grip section. The knob-shaped design of the control element makes it very easy to grasp manually, which optimizes the ease of use of the actuation device.
    Another embodiment of the actuating device according to the invention provides that the operating element is sealed off from the cover plate by an annular seal, for example an O-ring. In this way, the electrical contact elements arranged in the operating element and the integrated lighting technology can be protected against the ingress of moisture and / or dirt in a simple and reliable manner.
    The invention is explained in more detail below with the aid of a drawing showing an exemplary embodiment. 1 shows an actuating device according to the invention in the form of an actuating plate for a valve of a sanitary installation, in particular for a drain valve of a cistern, in a front view; FIG. 2 shows a section of the actuating plate from FIG. 1 in a top view as an exploded view; FIG. and FIG. 3 electrical contact elements and an associated electrical circuit board of the actuating plate according to FIG. 2 in a perspective detailed view.
    The actuating device 2 shown in the drawing is designed in the form of an actuating plate 3. It is used for the manual actuation of a valve in a sanitary installation, for example the actuation of a drain valve of a toilet cistern, in particular a concealed cistern. For this purpose, the actuating device 2 is provided with an operating element 6, which is preferably designed in the shape of a knob and, for example, has a knob-shaped grip section. The operating element 6 is rotatably mounted on a cover plate 4 which is mounted on an inspection opening of the cistern. The cover plate 4 is made of plastic, metal or glass, for example. The axis of rotation of the operating element 6 runs essentially perpendicular to the plate plane defined by the actuating plate 4 or cover plate.
    The drain valve (not shown) arranged in the cistern is preferably designed as a two-volume drain valve. It enables the optional delivery of a relatively large amount of flushing water or a relatively small amount of flushing water for full or partial flushing of a toilet bowl connected to the cistern.
    Depending on the direction of rotation, a partial flush or a full flush can be triggered with the operating element 6. Preferably, stops (not shown) are assigned to the rotatable operating element 6, which limit the range of rotation of the operating element 6 and haptically signal to a user of the operating device 2 that he has executed a rotary movement of the operating element 6 sufficient to trigger a flushing process.
    The control element 6 is preferably provided with a return means, for example a return spring (not shown), which automatically returns the control element 6 to a neutral or starting position after manual rotation of the same to trigger a full flush or partial flush and then release the control element 6.
    The knob-shaped operating element 6 is designed as a hollow body and contains lighting elements for illuminating the cover plate 4 or actuating plate 3. In FIG. 2 it can be seen that a circuit board 8 is arranged in the operating element 6. The circuit board 8 is equipped with lighting means 10, which preferably consist of LEDs. The lighting means or LEDs 10 are arranged on the side of the circuit board 8 facing the cover plate 4. The circuit board 8 with the lighting means 10 attached to it is connected or can be connected to the operating element 6 in a rotationally fixed manner.
    Furthermore, a reflector 12 is assigned to the lighting means 10, which reflector 12 is at least partially inserted into the knob-shaped operating element 6 in the fully assembled state of the actuating device 2. The reflector 12 is also connected or can be connected to the operating element 6 in a rotationally fixed manner. It is ring-shaped and has at least one recess (recess) in its central section for the passage or reception of electrical contact elements 16 (16a, 16b, 16c). In addition, the reflector 12 is conical. Its reflective outer surface increases starting from the lighting means 10 or from the interior of the operating element 6 in the direction of the cover plate 4. In the exemplary embodiment shown in FIG. 2, the reflective outer surface of the reflector 12 increases exponentially in the direction of the cover plate 4.
    The reflector 12 is combined with a light guide 14. The light guide 14 is also formed in the shape of a ring. The light generated by means of the lighting means 10 is directed into the light guide 14 via the reflector 12. The light guide 14 guides the light in the direction of the cover plate 4 and distributes it largely homogeneously as indirect lighting of the operating element 6 and as ambient lighting. The operating element 6 is preferably made of an opaque material or is at least partially coated with an opaque material.
    With the control element 6 and the circuit board 8 are connected to electrical contact elements 16, which are designed as sliding contacts in the illustrated embodiment. When the operating element 6 is rotated, the sliding contacts 16 are rotated at the same time.
    On the cover plate 4, a circuit board 18 is attached (see. Fig. 2 and 3), which is made of electrically non-conductive material, such as plastic, and on its side facing the operating element 6 with electrical contact surfaces 20, 22, 24 is provided. The electrical contact surfaces 20, 22, 24 are assigned the electrical contact elements 16 (16a, 16b, 16c, which are connected to the operating element 6 in a rotationally fixed manner. The contact surfaces 20, 22, 24 are made of highly conductive metal, e.g. copper.
    The two electrically isolated contact surfaces 20, 22, to which the electrical contact element 16a is assigned as a single sliding contact, allow the optional triggering of two different valve functions of a cistern drain valve, namely the triggering of a full flush and the alternative of a partial flush. For this purpose, an electrical actuator (not shown), for example a servomotor, an electromagnetic switch or the like, is connected to the contact surfaces 20, 22, so that a mechanical rotary movement of the operating element 6 is converted into electrical signals that enable the drain valve to be actuated by means of the electrical actuator cause.
    The lying between the contact surfaces 20, 22, electrically non-conductive area of the circuit board 18 defines the above-mentioned neutral or starting position in which the control element 6 after turning it to trigger a desired valve function and releasing it by the return means, for example a return spring, is automatically moved back.
    The two electrically isolated contact surfaces 24 are used to power the lighting means (LEDs) 10. The spaced apart contact surfaces 24 each have a length that corresponds at least to the distance between the opposite ends of the contact surfaces 20, 22. Each of the two contact surfaces 24 is assigned an electrical contact element 16b, 16c, which in turn is designed as a sliding contact. In contrast to the sliding contact 16a with the associated contact surfaces 20, 22 for triggering the valve function, the sliding contacts 16b, 16c electrically connected to the LEDs are in permanent contact with the contact surfaces 24 and thus ensure or enable permanent lighting.
    The contact surfaces 20, 22, 24 are preferably arranged on a common pitch circle. In this case, the contact surfaces 24 are preferably arcuate and each have an arc length which corresponds at least to the arcuate distance between the ends of the contact surfaces 20, 22 facing away from one another.
    The sliding contacts 16a, 16b, 16c preferably each have a spring element so that the respective sliding contact is resiliently biased against the circuit board 18 or the electrical contact surface 20, 22, 24 assigned to the sliding contact.
    The sliding contacts (contact elements) 16a, 16b, 16c are pin-shaped, each of the sliding contacts 16a, 16b, 16c having a sleeve 17, at the ends of which contact pins 16.1, 16.2 protrude axially, which are slidably guided in the sleeve 17 and are resiliently biased by at least one spring element arranged in the sleeve 17 in the direction of the respective sleeve end. Stops are provided at the sleeve ends which prevent the contact pins 16.1, 16.2 from accidentally falling out of the sleeve 17.
    The printed circuit board 18 is preferably designed in the shape of a ring. However, it can also be arcuate or have a different shape. To fasten the printed circuit board 18 to the cover plate 4, the printed circuit board has fastening holes 15 for receiving screws or other fastening means.
    Furthermore, an annular seal 19, for example an O-ring, is arranged between the operating element 6 and the cover plate 4. The seal 19 protects the lighting components arranged in the operating element 16 from moisture and contamination.
    On the front of the cover plate 4 accessible setting means 26, for example small pushbuttons, are provided with which the brightness and / or the light color of the LEDs 10 can be set manually.
    The embodiment of the invention is not limited to the embodiment shown in the drawing. Rather, numerous variants are conceivable which make use of the invention and its design specified in the appended claims even in the case of a design deviating from the exemplary embodiment. For example, the actuation device 2 can also have a twilight sensor assigned to the illuminant 10, which automatically switches the illuminant 10 on in certain light conditions in the vicinity of the actuation device 2 and switches it off again at a certain brightness.
