DE102007059591A1 - Vacuum cleaner, has filter cleaning mechanism detachably or inseparably connected to filter base and axial centrically rotates and comprising rotary wings and bristles that are connected by bristles holders - Google Patents

Abstract

The cleaner (1) has a filter cleaning mechanism (24) made of plastic or metal and comprising rotary wings (9, 16) and bristles (10, 17) that are connected by bristles holders (11, 18). The holders are connected to a guide axis penetration (20) and rotatably driven by suction air flow guided completely or partially, tangentially to the rotary wing (9) around the penetration on a turn table (23) of closing elements (22) or directly or indirectly by a motor shaft. The filter cleaning mechanism is detachably or inseparably connected to a filter base (27) and axial centrically rotates.

Description

The The invention relates to a vacuum cleaner with automatic filter cleaning device.

vacuum cleaner These types are described in the prior art and are in different embodiments also in use, usually with a great deal of technical effort high production costs is connected.

outgoing From this prior art, the invention is based on the object to present a filter cleaning device whose mode of action with simple and safe mechanics favorable production costs and has a long life.

Different according to the invention the arrangement of the type mentioned above primarily from previous Technologies in that the mechanically stiff filter with horizontal or vertically extending folds of axially concentric running around it and in physically related bristles passing through Rotary wing, which are positively or positively connected to the bristles, and by opposite the container wall tangentially and cyclone-guided Suction air flow are driven, so that the bellows filter adhering fine dust is effectively detached.

Is solved This object is achieved by the characterizing features of claim 1. Advantageous developments of the invention are characterized by that of this Claim dependent claims characterized.

In The following is the invention with reference to a preferred embodiment described in conjunction with a drawing.

there shows:

1 a simplified longitudinal section of the vacuum cleaner ( 1 ) with bellows filter ( 9 ).

Vacuum cleaners that work with dust filters will lose their suction power after a relatively short period of time as the filters become clogged with fine dust. If the motor is also cooled with the suction air flow, the motor can be destroyed by overheating when the suction air flow decreases. To reduce this disadvantage, the invention proposes that the mechanically stiff filter cartridge ( 15 ) of at least two offset by 180 ° to each other rotary wing ( 9 . 16 ) whose bristle frames ( 11 . 18 ) frictionally or positively with the Borstenn ( 10 . 17 ) are connected and via the web-shaped or circular guide axis ( 14 ) with the guide axis penetration ( 20 ) about the axis of rotation ( 21 ) on the turntable ( 23 ) of the closure element ( 22 ), which is captive with the Fixierholm ( 4 ), turns. The rotary wing ( 9 . 16 ) through the via the Saugluftstromöffnung ( 13 ) tangentially and cyclone-like on the rotary blades ( 9 ... n) guided suction air flow direction ( 12 ) clockwise in the direction of the rotary vane direction of rotation ( 19 ) driven turbine-like without further energy input. The filter cleaning device ( 24 ) can just as usual on the filter cartridge ( 15 ) are pushed, wherein by means of the closure element ( 22 ) both the filter cartridge ( 15 ) as well as the filter cleaning device ( 24 ) can be securely fixed in one operation. Via the optical window ( 25 ), the function of the filter cleaning device ( 24 ) to be watched.
