APPARATUS FOR DETECTING STAGNANT WATER

Abstract

An apparatus for detecting stagnant drinking water includes a generator for producing electrical energy, an energy store for storing that energy, a control and analysis unit which detects the charge state of the energy store and a signal transmitter which emits a signal depending on the charge state of the energy store.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The invention will be described in more detail below with reference to the attached drawing in conjunction with the described exemplary embodiment. The drawing shows:

[0043] FIG. 1: a schematic view of the basic construction of a detection apparatus in accordance with the invention.

DETAILED DESCRIPTION

[0044] The apparatus in accordance with the invention includes a generator 1, which is arranged in a pipe section (not shown). The generator 1 is driven by a turbine located in the pipe section through which water flows and thus produces electrical energy. The energy is stored in an energy store 2, which can be constructed, for instance, in the form of a capacitor. Reference numeral 3 designates a signal transmitter, which produces, for example, an optical signal when fresh water is at the tap connection. The components 1, 2 and 3 can be accommodated in a unit 4, which is, for instance, an end member or an intermediate member 4 for a water outlet.
