Definitions

  • the invention relates to a wet filter for a floor cleaning device, in particular a vacuum cleaner comprising a closed one Housing with one air inlet opening and one Air vent, with a liquid reservoir for intake a liquid bath and one leading to it, at the Air supply opening connecting air supply part.
  • wet filters are not special well, because after blowing the air into the water bath forming air bubbles collect dust particles and the liquid bath can go through without being wetted.
  • the exhaust vent contains air still a considerable proportion of particles, which again in the device the environment is released.
  • the invention is therefore based on the problem of a wet filter to indicate the improved cleaning and filtration enables.
  • the special advantage of the downstream of the air outlet opening Air duct part is that due to at least partially curved air guiding surface that meets it Air is redirected, generating centrifugal forces, which cause the heavier dust particles in Walk in the direction of the air duct surface. Because preferred because of that blowing in the suction completely under water Air this whirls up a considerable amount of water and with takes and thus a full coverage of the air duct surface causes the centrifugal force to deflect Dust particles on a wetting the air duct surface Water film and are bound there. This ensures that the dust particles are in contact with the this binding liquid, as well as such dust particles, immediately after blowing into the liquid reservoir have accumulated in a larger air bubble. This makes the cleaning and filtration effect remarkable improved, the escaping air is almost completely particle-free.
  • the air duct surface in the Is essentially directed towards the air outlet opening and is designed such that the air essentially in the direction is deflected to the air outlet opening. So the air will redirected towards the air outlet opening, resulting in remarkably high forces during this redirection process act on the dust particles.
  • the air duct which is arranged on the bottom side according to the invention, wherein the air duct surface is flat or also curved Has section on which the curved deflecting Sub-section connects, is substantially U-shaped.
  • the air outlet opening itself is according to the invention also provided close to the ground, so that on the one hand a complete Air is blown in below the liquid level, on the other hand, you can work with relatively little liquid become.
  • the from the area of the air duct towards the air vent contains flowing, cleaned and filtered air due to the design of the wet filter according to the invention a relatively high proportion of liquid.
  • Air duct part downstream further air duct part for Deflection of the air coming from the first air guide part is provided his. At this further air duct part takes place again a redirection of the air, with centrifugal forces are generated on the liquid carried by the air act and cause them to adhere to the air duct surface of the further air duct part, what leads to separation.
  • the further air duct part can be curved Air guiding surface, preferably with an essentially S-shaped one Have cross-section. Equally useful can also a plane, but at an angle to the direction of flow of the air guiding surface standing thereon is useful his.
  • the other air duct part differs the liquid contained in the air. Since the further air duct part the first air duct not only functionally, but can also be spatially downstream, collects in this case the liquid separated on it a housing area located behind the first air duct part. Provided that the first air duct part completely penetrates and separates it into two chambers, it has proven to be advantageous if near the ground of the first air guide part arranged at the bottom an opening to allow liquid to pass through from the area behind the air duct of the liquid reservoir provided in the front part is. The separated liquid can therefore flow back the liquid level in the reservoir fluctuates only slightly.
  • the wet filter itself can consist of plastic and executed in the form of a simple molded plastic part his.
  • additional separating web may be provided between the first and the further air duct part.
  • the flow velocity can be designed using this separating web influence and direction of the medium so that achieved an additional improvement in droplet separation can be.
  • the invention further relates to a Floor cleaning device, in particular a vacuum cleaner, comprising a wet filter of the type described above.
  • a wet filter 1 is shown, consisting of a housing 2 with side walls 3, a bottom 4 and a cover 5.
  • the housing 2 has an air supply opening 6, to which a tubular air supply part 7 connects in the example shown.
  • the air supply opening 6 is, for example, with the Suction hose of a vacuum cleaner, in which the wet filter shown 1 is integrated in connection.
  • the one loaded with dust particles Air is released due to the effect of a fan, not shown, which is connected downstream of the air outlet opening 21 of the housing 2 and to a negative pressure inside the housing 2 leads, sucked.
  • the tubular air supply part 7 leads into Liquid reservoir 8, in which washing liquid 9, in the Usually water is located.
  • the liquid level is so high or the air outlet opening 10 of the air supply part 7 so close to the ground arranged that the air escaping from it essentially blown in completely below the liquid level becomes.
  • a first air guiding part is connected downstream of the air outlet opening 10 11, which is attached to the bottom and one in Has a substantially U-shaped cross section.
  • the air duct 11 extends into the interior of the housing 2 and has a first in the example shown essentially flat Section 12, on which there is a curved section 13 connects.
  • the mode of operation is now such that the air entering below the liquid level hits the air guiding part 11. Due to the introduction of the air into the liquid, the air also takes liquid with it, which leads to the air guide surface 14 of the air guide part being wetted by the liquid carried along by the air flowing along it. The air is deflected at the curved section 13. Due to the centrifugal force acting thereby, which acts on the dust particles in the air, these are deflected in the direction of the air guide surface 14 and hit the liquid film wetting the air guide surface 14, ie they come into contact with it and are bound there. At the free-standing end 15 of the first air guiding part 11, the liquid film is heavily atomized and rains down into the liquid bath.
  • an air duct 16 which among other things from another air duct part 17, which in the case shown game has a substantially S-shaped cross section, limited becomes.
  • the cross section of the air duct 16 is sufficient large dimensions, so that there is a low flow rate sets.
  • the jet of air within this channel strikes the further air duct part 17, which arrives in this way the cover 5 is arranged so that the air is redirected again becomes.
  • the air is separated from the liquid.
  • the cleaned and liquid-free air passes over the Air outlet opening 21 and can be released to the environment become.
  • the escaping air another deflection, which leads to another Improves the separation effect.
