- the toilet also includes a flushing line connected to the toilet bowl, a user operation, and a flushing actuation coupled to the user's operation.
- Dual-flush toilets and toilets in which feces and / or urine can be flushed away with two or more than two different flush volumes are called multi-flush systems toilets in the context of the present invention.
- Toilets with dual flushing technology are widely used today in private households and public installations - especially in Central Europe.
- the user can adjust the water consumption to the effective flushing requirement when triggering the flushing process by choosing a large or small flush volume.
- a small one Flushing volume with low flushing results in a significantly lower water consumption, as in toilets with single-flushing, which are flushed in any case with the full (usually double) flushing.
- the water savings in such dual-flush systems is directly dependent on the behavior of the user: If the user does not select the flush volume according to the current flushing needs, but for example always uses the large flush volume, there is no water savings.
- Toilet flushing systems in which the flushing operation is not derived from a user's actuation by a directly mechanically coupled movement are also known.
- the actual flushing process (opening and closing a valve) is triggered by means of an electric, pneumatic, hydraulic or combined actuator.
- the operation of the user is usually recorded by a switch or sensor and transmitted as an electrical signal to the flushing system.
- the publication WO 2004/097123 Al discloses a system in which a use sensor in the toilet ceiling I is mounted, which detects the opening of the toilet lid and thus the presence of a person by means of radio waves or infrared rays. On the basis of a service life of, for example, more or less than one minute, the system concludes the presence of stool or urine in the toilet bowl and triggers a corresponding large or small conditioner.
- the publication US 2005/0028260 Al discloses the detection of a person present or using the toilet by means of an infrared measuring field. If the presence of a person extends to more than, for example, 10 seconds, an actual use is concluded and optionally a pre-purge is triggered. On the basis of the actual service life of, for example, more or Less than a minute is checked for the presence of stool or urine in the toilet bowl and a corresponding large or small flushing triggered.
