Claims6
A system encouraging users to cleanse their hands after use of a tankless toilet having a flush valve controlling the flow of water through a conduit into the toilet bowl, comprising:
- a sensor detecting the temperature of the conduit wall;
- means for interrogating said sensor at selected intervals;
- means for comparing the conduit wall temperature at the beginning of an interval with that at a succeeding interval;
- means detecting the rate of change of the conduit wall temperature;
- and
- means triggering a recorded announcement urging the toilet user to wash his or her hands upon detection of a preselected rate of change of the conduit wall temperature.

- detecting the rate of change of said temperature between said intervals;
- and
- triggering a recorded announcement urging the user to wash his or her hands when the detected rate of change of said temperature is greater than a preselected value.
