ABSTRACT:
The plumbing fixture, which can be actuated without physical contact, has a water line that is connected to a source of water and has a water outlet. A shut-off valve is disposed in the water line downstream of a mixer valve. A control unit controls the shut-off valve as a function of control signals from a proximity-sensitive sensor. A turbine is disposed in the water line for supplying electrical energy to the control unit. Permanent magnets are distributed equidistantly about an outer periphery of a wheel of the turbine. At the level of the permanent magnets, at least two magnet coils are provided in a tubular section of the water line. The coils cooperate with the permanent magnets to form a generator.
