Embodiment Construction

[0026] First refer to figure 1 A vacuum cleaner 1 is explained and illustrated, in particular a household vacuum cleaner designed as a manually guided handle unit. The hand-held device firstly has a base unit 2 with a motor, not shown, for the suction / blowing unit. A filter bag chamber 3 designed to accommodate sucked-up dust is provided on the basic device 2 . The chamber contains a filter bag 4 .

[0027] The electric motor integrated in the base unit 2 is supplied via the cable 5 .

[0028]Furthermore, the basic device 2 has a gooseneck-like projection which extends over the area of ​​the filter bag chamber 3 . A socket for the handle 6 of the vacuum cleaner 1 is molded into the protrusion in the region of the free end. An actuating grip 7 is arranged in the region of the free end of the handle 6 . The operating handle has a thumb-operable control unit in the form of a slide switch, via which control unit the power of the electric motor accommodated in the base unit 2 ...

Abstract

The bag (4) has a retaining plate (9), where a portion (13) of the bag rests at the plate in an unloaded condition. The portion (13) is provided with a lever section (14) for installing the bag in a filter bag chamber in the unloaded condition. The section is linked at the plate and has a portion provided at an angle of 10 degrees and pivoted by the plate. The section is prestressed in an installation position. A spring (18) is effectively arranged between the plate and the section for prestressing. The portion (13) of the bag is spaced at a distance from the plate.

Description

technical field [0001] The invention relates to a filter bag with a support plate, wherein at least a partial region of the filter bag bears against the support plate in the unloaded state. Background technique [0002] Filter bags of this type are known and are used in particular in vacuum cleaners, more particularly in household vacuum cleaners, for filtering the suction air containing dust and dirt during operation of the vacuum cleaner. In the unloaded state, that is to say without the filter bag being loaded with suction air, it is possible, in particular depending on the degree of filling of the filter bag, to place a partial region of the filter bag against the support plate in such a way that the inflow of the support plate The holes are at least partially covered. This situation also exists after inserting a new bag which has not been used and which is still at least partially folded. This can cause the device containing the filter bag, such as a vacuum cleaner, t...
