Definitions

• the invention relates to a contactlessly operated sanitary fitting with a water outlet, a mixing valve and a shut-off valve which is connected downstream thereof and is controlled by an proximity sensitive sensor and which is provided with an armature by a solenoid provided with an armature by means of a control device as a function of the control signals of the sensor can be actuated.
• shut-off valve inserted into the inlet pipe is designed as a magnetic valve and is connected to an electrical switching element as a control device, by means of which the magnetic valve is opened when a person approaches and water thus emerges from the outlet piece without manual contact.
• the electrical switching element and the solenoid valve can be supplied with electrical energy by connecting to the general power network.
• the object of the invention is therefore to design the sanitary fitting of the aforementioned type in such a way that it works almost maintenance-free and there are no operating costs and that deliberate damage by third parties is largely excluded. Above all, no connection to a power grid should be required, but reliable operation should nevertheless be ensured. In spite of the low construction effort, a risk of accident by electrical current should also be excluded.
• this is achieved by connecting the solenoid of the shut-off valve and the control unit directly or via an accumulator or a battery integrated in the sanitary fitting to one or more solar cells.
• the solar cells directly into the water outlet, for example a water tap, on one or more outer sides, preferably on the outer side thereof pointing vertically upwards
• the solar cells can also be arranged outside the sanitary fitting at a light-intensive point.
• the shut-off valve can be operated with a very weak current that can be generated by solar cells, it is appropriate to design it in such a way that it has a valve body inserted between its supply line and its discharge line, which can be acted upon on both sides by the inflowing water, for example in the form of a valve body has in the edge region clamped and provided with an air-flowable opening, the stroke movements of which can be triggered by a control element which acts in the manner of a seal and cooperates with a branch line which is passed through the valve body, preferably centrally, and which can be influenced by the armature of the solenoid , wherein in the magnetic coil of the shut-off valve a pole core interacting with a permanent magnet should be arranged in a fixed position, on which the armature is supported by a spring.
• control device it is also expedient to design the control device as an integrated circuit which can be intervened * by means of a switch built into the water outlet.
• a further advantage is that no electrical energy can be drawn from the power supply for operating the fitting, it rather supplies itself to a certain extent by converting light energy into electrical energy and storing it in the accumulator. Accordingly, there are no operating costs. And since the accumulator can be designed for the operating voltage of the solenoid of the shut-off valve, accidents caused by the given electrical voltage can be ruled out, even without improper handling, without special precautions, and furthermore a transformation of the electrical energy is possible not mandatory. A versatile, trouble-free use of the sanitary fitting designed according to the proposal is thus possible with little construction effort.

• an accumulator 17 designed as a rechargeable battery is connected via a line 18 to the control device 14 for supplying it with electrical energy and for supplying the magnetic coil 41.
• the water supply to the tap 7 is thus controlled by means of the control device 14 and this is supplied with mixed water from cold and warm water in accordance with the setting of the mixing valve 11.

• solar cells 23 can also be arranged at another light-intensive point and connected to the accumulator 17 via a line 24.
• the electrical energy converted by means of the solar cells 21 or 23 is stored in the accumulator 17 and, if necessary, fed via the line 18 to the control device 14 shown schematically in FIG.
• the sanitary fitting 1 is therefore always ready for operation regardless of a power supply and works almost maintenance-free.
• the shut-off valve 12 is installed in a housing 31 and consists of an adjustable valve body 35 in the form of a rolling membrane 36, which is located in its outer edge region with the aid of two clamping rings 33 and 33 ' this and a support 32 is clamped.

• shut-off valve 12 If the shut-off valve 12 is to be closed again because, for example, the sensor 13 signals that there is no longer any person in its area of influence, the solenoid 41 is only to be supplied with a reversed current surge via the control device 14. As a result, the magnetic force of the permanent magnet 51 is canceled and by the force of the spring 53, the control member 48 is pressed against the mouth 63 of the extension 61. As soon as the branch line 62 is thus closed, the same pressure builds up in the room B as in the room A.
