Method for adjusting the power of a vacuum cleaner fan, regulating device for implementing the method and vacuum cleaner with such a regulating device

The method involves tapping off a signal through a vacuum switch (24) with a single switching point. The tapped off signal is low-pass filtered to obtain a resulting signal. A measure is determined for vacuum pressure generated by a vacuum cleaner fan of a vacuum cleaner. Power of the vacuum cleaner...

Zusammenfassung:	The method involves tapping off a signal through a vacuum switch (24) with a single switching point. The tapped off signal is low-pass filtered to obtain a resulting signal. A measure is determined for vacuum pressure generated by a vacuum cleaner fan of a vacuum cleaner. Power of the vacuum cleaner fan is adjusted by using an electronic control system by a manipulated variable as a controlled variable depending on the pressure generated by the fan. The resulting signal is used as a actual value for the pressure and as the controlled variable for adjustment the fan power. Independent claims are also included for the following: (1) an electronic control system for a vacuum cleaner (2) a vacuum cleaner.
