Abstract:
1. A method of operating a toilet freshener comprising a sensor unit, a control unit, a release element, and at least one container for storing at least one preparation, the release element and the container being connected together in communicating manner, the method comprising: flushing water flow through the toilet bowl within a flushing water period [t detecting, using the sensor unit, triggering of a flush water stream through the toilet bowl within the flushing water period [t sending a sensor signal, which represents triggering of the flush water stream, to the control unit; converting the sensor signal, using the control unit, into a control signal for the release element, in response thereto, to release preparation from the container into the interior of the toilet bowl, release of the preparation from the container by the release element taking place with a time delay Δt after detection of the flush stream by the sensor unit at the time t detecting an ending of flush water flow through the toilet bowl; sending a second sensor signal, which represents ending of flush water flow through the toilet, to the control unit; and converting the second sensor signal, using the control unit, into a second control signal in response thereto for terminating active substance release once flush water has stopped flowing through the toilet bowl, wherein no preparation is released if the sensor unit has detected the end of flush water flow.
