Abstract

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Bestimmung des Füllgrades eines in einem Staubsauger (1) mit einem Antriebsmotor (4) angeordneten Staubabscheide- und Sammelorgans sowie auf einen Staubsauger (1) mit einem Antriebsmotor (4), einem Staubabscheide- und Sammelorgan und einer Vorrichtung zur Erfassung des Füllgrades des Staubabscheide- und Sammelorgans.The present invention relates to a method for determining the degree of filling of a vacuum cleaner in a (1) with a drive motor (4) Staubabscheide- and collecting organ and on a vacuum cleaner (1) with a drive motor (4), a Staubabscheide- and collecting organ and a device for detecting the degree of filling of Staubabscheide- and collecting organ.

Um den Füllgrad des Staubabscheide- und Sammelorgans messen zu können, wird für das Verfahren vorgeschlagen, dass eine Auswerteelektronik beim Betrieb des Staubsaugers (1) die absolute und/oder relative Drehzahl des Antriebsmotors (4) als Ist-Wert ermittelt, mit einem Referenzwert für die Drehzahl vergleicht und aus dem Vergleich einen Indikatorwert für den Füllgrad ableitet. Für den Staubsauger wird vorgeschlagen, dass die Vorrichtung eine Auswerteelektronik aufweist, von der mit einer geeigneten softwaregesteuerten Schaltung
• eine aktuelle Drehzahl des Antriebsmotors (4) als relativer und/oder absoluter Ist-Wert ermittelbar,
• ein Referenzwert zugreifbar,
• eine Differenz und/oder ein Quotient zwischen dem Ist-Wert und dem Referenzwert bestimmbar und
• aus der bestimmten Differenz und/oder dem bestimmten Quotienten ein Wert für den Füllgrad des Feinstaubfilters (3) ableitbar ist.

Figure imgaf001
In order to be able to measure the degree of filling of the dust collecting and collecting element, it is proposed for the method that an evaluation electronics determines the absolute and / or relative speed of the drive motor (4) as the actual value during operation of the vacuum cleaner (1), with a reference value for compares the speed and derives from the comparison an indicator value for the degree of filling. For the vacuum cleaner, it is proposed that the device has a transmitter, of which with a suitable software-controlled circuit
A current speed of the drive motor (4) can be determined as a relative and / or absolute actual value,
• a reference value accessible,
• a difference and / or a quotient between the actual value and the reference value can be determined and
• From the determined difference and / or the specific quotient a value for the degree of filling of the fine dust filter (3) can be derived.
