Triggering of a cleaning, ventilating, and/or disinfecting process

摘要

A method for triggering a cleaning, ventilating, disinfecting and/or deodorising operation in washrooms and/or toilet rooms, by means of an acoustic sensor arranged in close proximity to a flushing and/or inflow operation of a liquid and having an adjustable signal amplifier and filter, characterised in that a frequency band filter is connected upstream of the signal amplifier and is tuned to the characteristic spectral range of the triggering operation in which the sound frequencies with the maximum energy lie.
