Definitions
- a water fitting according to the preamble of claim 1 is known from EP-A-688.909. It is a water valve with electrical control.
- a nozzle has connections for cold and hot water.
- An adjustable mixing valve is installed in the nozzle. This is followed by a solenoid valve, the outlet of which opens into an arm with a water outlet mouthpiece.
- a presence detector is also installed in the nozzle, which automatically switches on the solenoid valve when one hand approaches. »
- the present invention has for its object to achieve a safe assembly and disassembly of the housing for maintenance. This object is achieved by the characterizing features of claim 1.
- FIG. 1 shows a longitudinal section through a water fitting
- FIG. 2 shows a perspective view of the sensor
- FIG. 3 shows a circuit diagram of the water fitting according to the invention.
- the water fitting u holds a cylindrical socket 1, which is attached to a sink 2, for example.
- the connector 1 has at least one water connection 3.
- the connection 3 is connected via a line 4 to the input of a solenoid diaphragm valve 5. Its outlet leads to an outlet duct 6.
- In Spigot 1 also contains a known electronic unit 8 with a proximity sensor 9 for automatically switching on the valve 5 when a hand approaches, which is battery-operated.
- the proximity sensor 9 is designed as a light barrier, with a transmitting diode 10 and a receiving diode 11.
- a tubular, curved housing 15 is plugged onto the connector 1 and secured with a screw 16.
- An outlet line 17 is arranged in the housing 15 and is connected to the channel 6 via a pluggable line 18.
- the free end 19 of the screw 16 protrudes into a connector 20 arranged between the diodes 10, 11 on the unit 8.
- the connector 20 has a longitudinal slot 21 on the connecting line between the diodes 10, 11, which slot is narrower than the diameter of the end 19
- the housing 15 has a window 22 made of a transparent pane.
- the receiving diode 11 measures not only the light reflected by the approaching hand, but also reflected light from the immediate vicinity of the diodes 10, 11.
- the unit 8 is tuned during operation in such a way that this stray light has no influence on the functioning of the valve Has.
- the unit 8 is now designed according to the invention in such a way that the valve 5 is automatically switched off when this state occurs.
- the unit 8 thus has not only a lower limit for the light intensity received by the receiving diode 11, when it is exceeded, the valve 5 turns on, but also an upper limit, when it is exceeded, the valve 5 is automatically turned off, regardless of whether a hand is near the sensor 9 or not. Both limit values can be set.
- the scanning can also be carried out with a special receiving diode (2 receiving diodes).
- the valve 5 closes with a delay in response to the closing signal. Because unscrewing the screw 13 takes a certain time, it is ensured that the valve is closed in time before the housing 17 can be pulled away from the connector 1.
- the configuration according to the invention ensures that when the housing 15 is removed for maintenance purposes, e.g. to change the battery, no water can leak out of the fitting.
- the design according to the invention is of course also suitable for fittings with a cold and hot water connection and an adjustable mixing valve which is upstream or downstream of the switching valve 5.
