Abstract

Die Erfindung betrifft ein Verfahren zur Füllstandsüberwachung bei einem Staubsauger (1), wobei im Betrieb Daten für einen vom Antriebsaggregat des Staubsaugers (1) erzeugten Unterdruck und Volumenstrom aufgenommen werden, wobei in einem Speicher (30) Daten (32) für volumenstromabhängige Kennlinien (20, 21) abgelegt sind, wobei zumindest anhand des tatsächlichen Volumenstroms ein Arbeitspunkt (26) auf einer Kennlinie (20,21) und ein mit dem Arbeitspunkt (26) auf der Kennlinie (20,21) verknüpfter Unterdruck ermittelt werden und mit dem tatsächlichen Unterdruck und dem Wert für den Unterdruck anhand der Kennlinie (20, 21) ein momentaner Füllstand des Staubsaugers (1) ermittelt wird und/oder wobei anhand des tatsächlichen Volumenstroms und Unterdrucks ein aktueller Arbeitspunkt (24) ermittelt und zu der oder den Kennlinien (20, 21) so in Beziehung gesetzt wird, dass aus der oder den Kennlinien (20, 21) zumindest eine zu diesem am besten passende ausgewählt wird und sich der momentane Füllstand des Staubsaugers (1) anhand der ausgewählten Kennlinie(n) (20, 21) und einer Füllstandssituation, für welche diese ursprünglich aufgenommen wurde, ergibt.

The invention relates to a method for level monitoring in a vacuum cleaner (1), wherein in operation data for one of the drive unit of the vacuum cleaner (1) generated negative pressure and flow rate, wherein in a memory (30) data (32) for volume flow-dependent characteristics (20 , 21), wherein at least on the basis of the actual volume flow, an operating point (26) on a characteristic curve (20, 21) and a negative pressure associated with the operating point (26) on the characteristic curve (20, 21) are determined and with the actual negative pressure and the value for the negative pressure on the basis of the characteristic curve (20, 21) a current level of the vacuum cleaner (1) is determined and / or wherein based on the actual volume flow and negative pressure a current operating point (24) and determined to the one or more characteristics (20, 21) is set in such a way that from the one or more characteristic curves (20, 21) at least one best matching is selected and the mo mentane filling level of the vacuum cleaner (1) based on the selected characteristic (s) (20, 21) and a level situation for which it was originally recorded results.
