Definitions

  • the present invention relates to a method for operating a sanitary fitting and a sanitary fitting.
  • the sanitary fitting can be used in particular to provide a liquid as required at a washbasin, sink, shower and/or bathtub.
  • Sanitary fittings can have electrical loads that can be used, for example, to provide additional functions and/or convenience functions. Batteries are often used to supply energy to the electrical loads. To prolong battery life, it is desirable to turn on electrical loads only when water is being dispensed through the plumbing fixtures. Mechanical solutions are typically used for this, but they can often be susceptible to dirt (such as in the case of float switches) or only respond at higher flow rates of the water (such as in the case of turbines).
  • the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to specify a method with which the energy requirement of a sanitary fitting can be reduced without using dirt-prone means.
  • a sanitary fitting is to be specified whose energy requirement can be reduced without using dirt-prone means.
  • Steps a) and b) and steps a) and c) can be carried out at least partially with a time overlap. Steps b) and c) can be carried out consecutively.

If the valve is at least partially opened, the liquid line fills with liquid, so that the pressure in the liquid line increases. In particular, the liquid (along a flow path of the Dam up liquid in the liquid line) upstream of the mousseur, so that a dynamic pressure is created that adds to the air pressure around the sanitary fitting.

  • “Deactivating” can be understood here in particular as switching off the electrical load and/or resetting the electrical load to the stand-by mode. Furthermore, the deactivation can include interrupting the supply of electrical energy to the electrical consumer and/or disconnecting the electrical consumer from the energy supply. After deactivation, the electrical consumer can be in a non-operational state. Furthermore, the electrical load consumes no electrical energy or at least less electrical energy in the deactivated state than in the activated state. This reduces the energy consumption of the sanitary fitting.
  • the digital barometer is insensitive to contamination that can be carried along in the liquid, for example.
  • the digital barometer in step c), can be put into an idle state or stand-by mode, as a result of which the energy consumption can be further reduced. For example, in the quiescent state, the digital barometer may require approximately 10 ⁇ A (microamps) at 3 volts.
  • the digital barometer continues to regularly measure the pressure in the liquid line. If the pressure in the liquid line rises above the threshold value again, step b) is repeated. If the pressure in the liquid line then drops below the threshold value again, step c) is repeated, etc.
  • the digital barometer can measure pressure at a frequency greater than 1 Hz (Hertz). In particular, the digital barometer can measure pressure at a frequency of at least 2 Hz. In particular, this can mean that the digital barometer measures the pressure in the liquid line in step b) and/or in step c), in particular continuously, several times per second.
  • 1 Hz Hertz
  • the digital barometer can measure pressure at a frequency of at least 2 Hz. In particular, this can mean that the digital barometer measures the pressure in the liquid line in step b) and/or in step c), in particular continuously, several times per second.

  • the threshold value can preferably be 1080 hPa to 1260 hPa, particularly preferably (approximately) 1100 hPa.
