Definitions

  • the invention relates to a vacuum cleaner according to the preamble of claim 1.
  • Such a vacuum cleaner suitable for vacuuming dry, moist or wet dirt is known from DE-C-39 00 083.
  • a film bag consisting of impermeable material is held clamped with its opening edge between a peripheral edge provided on the wall of the dirt collecting space and a supporting part which can be placed on this peripheral edge.
  • the support part itself is designed as a stable molded part, on which a corresponding holder for an exchangeable, tubular filter part is provided.
  • the supporting part of this vacuum cleaner When disposing of a foil bag filled with dirt, the supporting part of this vacuum cleaner must be removed so that the foil bag is completely open.
  • a ring cord is provided in the area of the opening edge with which the film bag can be tied together, but tying is only possible after the support part has been removed. When tied together, dirt can escape from the film bag.
  • the replacement of the filter part is also relatively unsanitary, since the dirty filter part must be grasped and removed from the support part and then disposed of.
  • the invention has for its object to develop a vacuum cleaner of the generic type so that the change of a filled filter bag is possible in a hygienically perfect manner.
  • the problem is solved by the features specified in the characterizing part of claim 1.
  • the dirt suction device With such a design of the dirt suction device, the dirt is sucked into the filter bag from above, so that it is deposited in the lower region of the filter bag, particularly when it is moist or liquid.
  • the filter part therefore remains effective for all types of dirt. Since the support part is firmly connected to the bag and filter part, this remains covered by the support part even when the filter bag is changed, so that escape of dirt is prevented, in particular if the inlet opening of the support part is assigned a closure flap through which the Inlet opening when changing the filter is completely closable.
  • the relatively small inlet opening at the top largely prevents any escape of dirt or liquid anyway.
  • the filter part of the filter bag is designed to be moisture-proof.
  • the filter part of the filter bag is designed to be moisture-proof.
  • a weight reduction facilitating the removal of the cover part is achieved in a dirt vacuum cleaner designed according to the features of claim 6.
  • the filter bag 4 consists of a bag part 9 fastened with its opening edge 5 between two cardboard layers 6 and 7 of a rigid, plate-shaped support part 8 and a filter part 10, which with its peripheral edge 11 on the circumference of a passage opening 12 formed in the support part 8 also between the cardboard layers 6 and 7 is attached.
  • the bag part 9 is made of impermeable material, e.g. made of plastic film.
  • the supporting part 8 rests on a peripheral edge 13 formed on the inside of the dirt collecting space 3 and is held clamped between the latter and the peripheral edge 13 by a cover part 14 covering the dirt collecting space 3.
  • a float valve 18 is also connected to the cover part 14. This consists of a float 20 arranged in a cage 19 and a valve outlet opening 21. In terms of flow, an additional filter 22 is also installed in the cover part 14 behind the valve outlet opening 21.
  • the interior 23 of the cover part 14 is in suction connection with the blower 25 of the vacuum cleaner via a suction channel 24 formed in the housing 1 of the vacuum cleaner.
  • the suction air flow generated by the fan 25, indicated by arrows 26, passes through the suction opening 17, the pipe part 16 and the inlet opening 15 into the bag part 9 of the filter bag 8.
  • the dirt contained in the suction air flow is already largely deposited on the bottom of the bag part 9, in particular when the dirt is wet or even liquid suction material.
  • the dirt parts remaining in the suction air flow after flowing through the bag part are largely retained.
  • a further filtering is then carried out again by the additional filter 22, which can be made more fine-pored than the filter part 10.
  • a contraction of the bag part 9 as a result of the negative pressure generated during suction can be prevented in a simple manner by providing openings 27 in the support part 8 which open outside the bag part 9 fastened to the support part 8 into the dirt space 3.
  • the pressure prevailing in the interior 23 of the cover part in the dirt collecting space 3 is effective via these openings.
  • the pressure in the dirt collecting chamber 3 is lower than the pressure in the filter bag 4.
  • the bag part 9 of the filter bag 4 is accordingly inflated and optimally fills the dirt collecting chamber 3.
