Definitions
- the invention relates to a blow-out filter on Housing of floor care devices, in particular Vacuum cleaner, one via a suction channel
- Motor upstream dust collection unit such as a Filter bag and if necessary a motor protection filter are arranged and the exhaust air via air outlets is guided outside in the housing.
- the aim is Blow-out duct and the exit point in the area of the To make the vacuum cleaner housing as large as possible, to have a low blowout resistance cause. Contrary to these requirements but also a reduction in noise emissions required by a relatively large Flow resistance could be achieved. This conflicting demands so far cannot be solved in a satisfactory manner.
- EP 0 706 774 B discloses the exit cross section corresponding covered openings in the form of Housing slots in the side walls of the housing to increase as a protective bandage.
- the object of the invention is to easily Outflow area further increase and small Allow flow velocities and a To ensure sound insulation.
- the low flow rate in the filter area also has the advantage that a high The degree of separation of suspended matter is achieved.
- By the relatively large filter volume is still a very large one long filter life guaranteed.
- a simple training is created in that the tubular filter material on both End faces with fasteners to the housing releasably used sealing and in the engine compartment facing area passages are formed.
- Filter material is designed in microfilter quality.
- the external filter material through a elastic support body is held.
- a housing 1 arranged with a suction channel 2 as a hose is provided and in the housing 1 in a load Filter bag 3 opens and one below the Filter bag 3 arranged engine 4 in an engine compartment 5th having.
- the motor 4 is in a known manner Motor protection filter 6 upstream.
- the housing 1 is in its cylindrical region wrapped like a hose by a filter material 7.
- the Filter material 7 is on fasteners 8, 9 on Housing 1 releasably connected and opposite Sealed outside.
