摘要

The invention relates to a method for the operation of a dust collection chamber (3) for an electrically driven vacuum cleaner (1), such as household vacuum cleaners or automatically movable suction device, wherein the dust collection chamber (3) has an inlet opening (10) and has an outlet opening (12), further including the outlet opening (12) is a filter element (14) is associated with. For further improvement in particular with regard to the emptying of the dust collection chamber, it is proposed that in the case of introduction of an emptying of the dust collection chamber (3), in addition to a suction device by means of a discharge outlet (4), which is also the inlet opening (10), and, if appropriate, a sucking in of air through the outlet opening (12), a sucking in of air through a further, in the dust collection chamber (3) and opening (17) is carried out. Furthermore, the invention relates to such a dust collection chamber (3), wherein further in the flow direction (b) in the case of conventional operation of the vacuum cleaner (1) in front of the filter element (14) is a dust discharge opening (4) is arranged. For further improvement in particular with regard to a favorable up to complete emptying of the dust collection chamber, it is proposed that a further, in the dust collection chamber (3) and opening (17) is provided, which in any case in a emptying operation the drawing of air into the dust collection chamber (3) allows.
