  • An object of the present invention is to achieve the highest possible energy efficiency in the operation of vacuum cleaners. That is, to ensure the highest possible dust and / or dirt intake at the lowest possible power consumption.
  • an apparatus for controlling automatic cleaning of a filter unit for an electric vacuum cleaner having a suction nozzle, a dust collecting unit and a motor / blower unit comprises: means for determining a first value of a suction air flow of the vacuum cleaner and means for adjusting a second value of the motor / blower unit of the vacuum cleaner in dependence on the determined first value of the suction air flow.
  • the device is set up to activate an automatic cleaning of the filter unit when a predetermined limit value of the motor / blower unit of the vacuum cleaner is exceeded by the second value and a predetermined limit value of the suction air flow of the vacuum cleaner from the first value of the suction air flow is exceeded ,
  • a cleaning of the filter unit can be initiated, which significantly improves the energy efficiency of the vacuum cleaner.
  • low power motor / blower units for vacuum cleaners can be provided.
  • first value is a value that more closely determines a suction airflow
  • second value is a value that more closely determines the engine / blower unit.
  • Another aspect of the invention relates to a method for controlling automatic cleaning of a filter unit for an electric vacuum cleaner having a suction nozzle and a motor / blower unit, comprising the steps of: determining a first value of a suction air flow and adjusting a second value of the power of the motor - / blower unit of the vacuum cleaner in dependence of the determined first value of the suction air flow.
  • the automatic cleaning of the filter unit is activated when a predetermined limit value of the motor / blower unit of the vacuum cleaner is exceeded by the second value and a predetermined limit value of the suction air flow from the first value is exceeded.
  • the method can be used particularly effectively with the previously described device for increasing the energy efficiency of the vacuum cleaner.
  • Yet another aspect of the invention relates to a computer program product for implementing the method in an apparatus for controlling an automatic cleaning of a filter unit for an electric vacuum cleaner with a suction nozzle and a motor / blower unit comprising program parts which, when loaded in a computer, designed to carry out the above method.

  • the first value of the suction air flow of the vacuum cleaner is proportional to a volume flow value of the vacuum cleaner and the second value of the motor / blower unit is proportional to a power value of the vacuum cleaner.
  • a measurement equivalent to the volume flow value can be particularly expedient via a pressure measurement or a pressure difference measurement of the suction air flow, a rotational speed determination, calculation of a recording power or current and / or voltage determination at the motor / fan unit respectively. Analogously, equivalent measurements can also be made to determine and adapt the motor / fan unit.
  • Deviations of a suction power can be compensated by, for example, the power value of the motor / fan unit of the vacuum cleaner is adjusted with decreasing volume flow value of the suction air flow upwards. However, this adjustment is made only until a certain power limit of the motor / fan unit of the vacuum cleaner is reached. If the power value is no longer sufficient or if the power limit of the motor / blower unit has been exceeded, the device automatically triggers the cleaning of the filter unit. Subsequently, the volume flow value of the suction air can be adjusted again by means of the power value of the motor / blower unit of the vacuum cleaner. In this way, the first value, the volume flow value, can be kept substantially constant.
  • the device is set to set the limit value of the motor / blower unit of the vacuum cleaner and / or the limit value of the suction air flow depending on a particular floor covering.
  • control of the motor / blower unit of the vacuum cleaner allows to achieve a higher energy efficiency by the suction power is adjusted depending on the detected surface, for example, hard floor or carpet accordingly.
  • a vacuum switch can be used.
  • it can be prevented that a force required for moving the suction nozzle, which is referred to as a pushing force hereinafter increases, and thus a use of the vacuum cleaner is difficult.
  • a physical difference to be detected for example, a pressure difference is selected such that in a change of the floor covering, for example, from hard floor to carpet and the associated negative pressure change in a dust chamber of the vacuum cleaner essentially nothing changes.
  • the detected physical difference size should thus be mainly independent of the floor covering to be suctioned off and instead primarily dependent on a filling level of the dust separation unit.
  • a power adaptation of the motor / blower unit which is essentially dependent on the fill level of the dust removal unit, can take place.
  • the detected physical difference quantity is preferably proportional to a volume or weight of a dust amount received by the dust collecting unit.
  • the device is arranged to determine the first value of the suction air flow, wherein a first air pressure value is detected upstream of the suction air flow, a second air pressure value is detected downstream of the suction air flow, and a differential pressure between the first and the second air pressure value is determined.

  • the first value of the suction air flow is determined by detecting a first air pressure value upstream of the suction air flow; a second air pressure value becomes downstream of the suction airflow is detected and a differential pressure between the first and the second air pressure value is determined.
  • the first air pressure value upstream of the suction air flow upstream of the filter unit of the vacuum cleaner is detected, and the second air pressure value downstream of the suction air flow downstream of the filter unit of the vacuum cleaner.
  • the first air pressure value upstream of the suction air flow is detected before a Staubabscheideiki the vacuum cleaner and detects the second air pressure value downstream of the suction air flow to the Staubabscheideisme the vacuum cleaner.
  • This procedure is particularly suitable for vacuum cleaners with filter bags, which usually have a further downstream of the Staubabscheidetician filter. Thus, even more factors can be taken into account, which can be responsible for a resistance of the suction air flow.
  • the first value of the suction air flow is determined as a function of a degree of filling of the dust separation unit.
