Definitions

  • the invention relates to a vacuum cleaner with a suction fan for the working air, a drive motor for the Suction fan, a cooling fan for the drive motor, with separate air channels for cooling air and working air.
  • the cooling air is through the motor pulled and tears out small particles, mostly the carbon abrasion of the commutator brushes of the electric motor With. These particles are released into the ambient air with the cooling air submitted.
  • the working air is generally before entering the Filtered suction fan, so that the coarse sucked up Dirt remains in the dirt container or in the filter bag.
  • the first filter device generally leaves finest dirt particles enter the air turbine, so that this then with the working air at the working air outlet be released into the environment again.
  • the object and the aim of the present invention exist in a vacuum cleaner of the type described above to find, where the delivery of coal abrasion of the drive motor from the cooling air flow into the ambient air and from finest dirt particles from the working air flow into the Ambient air prevented in a simple and inexpensive way becomes.
  • This is the beginning of a vacuum cleaner described type achieved in that the outlet of the Cooling air duct from the housing next to the outlet of the Working air duct from the housing is arranged that downstream immediately in front of the air outlet ducts Filter cartridge is provided which has a filter area for the cooling air and a filter area for the working air has, the filter areas within the filter cartridge are separated from each other in terms of flow.
  • a particularly advantageous construction results from that the filter areas inside the cassette are separated by a Partition are separated.
  • both filter areas are advantageously included Filter materials equipped with different degrees of separation.
  • the particles that flow with the cooling air Cases are carried out, mostly have a coarser Grain as the particles that are carried away with the flow of working air become.
  • the particle fraction of the cooling air flow can be determined very precisely from experience, so that for the area of the cooling air the filter material is very precisely selected and matched to the desired degree of separation can be. In this way, the filter material with the lowest possible degree of separation for the cooling air area to be selected.
  • a significant cost saving is possible if the filter material a lower degree of separation in the cooling air area has than the filter material in the working air area the filter cassette.
  • the finest particles in the working air area can cause allergenic reactions in humans and should therefore by the filter according to the invention will be held back, therefore advantageously Filter material in the working air area of the cassette 1 - 2 Filter classes according to DIN EN1822-1 higher than that Filter material in the cooling air area of the filter cassette.
  • the lifespan of the filter is determined by the amount of air or the size of the filter area.
  • the filter cassette according to the invention with the different Filter materials can be used optimally, if the filter area in the cooling air area of the filter cassette is smaller is the filter area in the working air area Filter cartridge.
  • the lifespan of the two filter materials can be adjusted so that both Filter materials lose their effect at the same time and need to be replaced.
  • Figures 1-4 are different sections through the shown upper part of a vacuum cleaner. This upper one Part is sealed on a not shown Dirt container attached.
  • the dirt container, not shown contains an inflow opening for connecting the Vacuum cleaner suction tool.
  • the working air flow is shown by arrows.
  • the working air flow comes from the dirt container through the suction opening 2 in the housing 3 of the vacuum cleaner in the suction fan 1. Upstream of the passage opening 2 is a main filter device for the sucked-in, dirty air flow.
  • the pre-filtered air flow is through the suction fan 1 and through the working air duct 4 to the outlet 5 of the Working air duct 4 out.
  • the drive motor is a Electric motor with rotating rotor and fixed stator, with carbon brushes attached to the stator 8.
  • a filter cassette 12 Downstream immediately in front of the outlet openings 10, 5 a filter cassette 12 is provided in the housing 3, which a filter area 13 for the cooling air and a filter area 14 for the working air.
  • the filter areas 13, 14 are inside the filter cartridge 12 through an intermediate wall 15 fluidically separated from each other.
  • the two filter areas 13, 14 are different Filter materials 16, 17 equipped.
  • the filter material 16 in the working air area is around 1 - 2 filter classes according to DIN EN1822-1 higher than the filter material 17 in the cooling air area of the filter cassette.
