Abstract

Eine Vorrichtung zur Bestimmung eines Füllgrades eines Staubsammelbehälters (1) für einen Staubsauger mit einem Fliehkraftabscheider (3), umfasst mindestens ein Resonatorelement (5), welches an einer Außenwand (4) des Staubsammelbehälters (1) gehaltert ist, ein Erregerelement (6; 6'), welches das Resonatorelement (5) zu mechanischen Schwingungen anregt, und eine Detektionseinheit (9; 9'), welche eine eine Dämpfung der mechanischen Schwingung charakterisierende Größe erfasst und welche abhängig von der ermittelten Größe den Füllgrad des Staubsammelbehälters (1) bestimmt.

Figure imgaf001
An apparatus for determining a degree of filling of a dust collecting container (1) for a vacuum cleaner with a centrifugal separator (3) comprises at least one resonator element (5) which is mounted on an outer wall (4) of the dust collecting container (1), an excitation element (6; '), which excites the resonator element (5) to mechanical vibrations, and a detection unit (9; 9'), which detects a characterizing a damping of the mechanical vibration quantity and which determines the degree of filling of the dust collection container (1) depending on the determined size.
