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.

First claim

The invention claimed is:

1. Apparatus for detecting stagnant drinking water, including
a generator for producing electrical energy,
an energy store for storing the electrical energy,
a control and analysis unit, which detects a charge state of the energy store, and including
a signal transmitter, which emits a signal depending on the charge state of the energy store, wherein the energy store is so selected that a discharge time of the energy store is shorter than a time period after which the drinking water is considered to be stagnant.

2. Apparatus as claimed in claim 1 , wherein the signal is an optical signal.

3. Apparatus as claimed in claim 1 , wherein the apparatus is constructed as an end member or an intermediate member for a water outlet.

4. Apparatus as claimed in claim 3 , wherein the water outlet comprises a water faucet.

5. Apparatus as claimed in claim 1 , wherein the energy store is constructed in the form of a capacitor.

6. Apparatus as claimed in claim 1 , further comprising an input device, by means of which the control and analysis unit can be supplied with a time period.

7. Apparatus as claimed in claim 1 , further including a temperature sensor.

8. An apparatus for detecting stagnant drinking water, including
a water system unit;
a generator for producing electrical energy;
an energy store for storing the electrical energy;
a control and analysis unit, which detects a charge state of the energy store, and including
a signal transmitter, which emits a signal depending on the charge state of the energy store, wherein the energy store is so selected that its discharge time is shorter than a time period after which the drinking water is considered to be stagnant; and,
wherein the generator, the energy store and the control and analysis unit are mounted to the water system unit.

9. The apparatus of claim 8 , wherein the signal is an optical signal.

10. The apparatus of claim 8 , wherein the water system unit comprises an end member or an intermediate member for a water outlet.

11. The apparatus of claim 10 , wherein the water outlet comprises a water faucet.

12. The apparatus of claim 8 , wherein the energy store comprises a capacitor.

13. The apparatus of claim 8 , further comprising an input device, by means of which the control and analysis unit can be supplied with a time period.

14. The apparatus of claim 8 , further comprising a temperature sensor.
