Definitions

  • the invention relates to a brush cleaning device, in particular for carpets, according to the preamble of claim 1 (see EP-A-0 315 068).
  • Such brush cleaning devices are known. This are used especially for cleaning carpets, the driven brushes rotating in the Intervene in the pile of the carpet to be maintained and loosen dirt particles.
  • the brush drive is preferably done electrically.
  • they are also devices known in which the brushes have a mechanical Implementation through the movement of the brush cleaning device are driven.
  • the one in the brush cleaner stored brushes are vertically movable, in the known versions rocker constructions be used. The latter serve to balance the Bristle wear of the brushes and for pile height adjustment.
  • Brush cleaning devices are also known which also contain drivable brushes, for Massage or evenly distribute detergents, especially cleaning granules. Hereby should prefer heavily soiled carpets be refreshed.
  • these drivable Brush on their bristles deeper into the carpet pile intervention. A higher one is also preferred here Support weight for improved massaging of the cleaning agents.
  • the object of the present invention is a generic Training brush cleaning device more convenient.
  • the brush cleaning device prevents the area of the brushes.
  • a foot switch or the like which when actuated, a rocker construction of the drivable Brushes in a vertically lowest position and at the same time the suction in a contact switch Prevents the area of the brushes.
  • a preferred one Configuration brushes are provided, wherein these have a smaller diameter than that first brushes.
  • stored brushes are worn in a known manner or replaceable defect. It is suggested for treating carpets with a cleaning agent replace these brushes with exchange brushes. The latter have a smaller diameter than that first brushes, which when fixed in a vertical lowest position of the brushes now relatively further down with respect to a bottom of the brush cleaner protrude.
  • the Bristles of the replacement brushes deeper into the pile of intervene carpets to be treated, which improved Massage the detergent into effect.
  • the replacement brushes When the replacement brushes are inserted, they become automatic set in a vertically lowest position.
  • the replacement brushes have a radial collar that has a suction opening of the brush cleaning device closes.
  • the replacement brushes or the brush body is conceivable from a different, a heavier material to manufacture than the first brushes. This will be a higher total weight of the brushes, resulting in a desired higher contact weight when massaging of the cleaning agent.
  • the replacement brushes with a closure part are designed for the suction channel of the device.
  • the closure part the suction channel transformed to an outer face of the brushes.
  • the suction is therefore not switched off, but rather a redirection of the suction channel from Area of the brushes away to an outer face the brushes.
  • the brush cleaning devices known on the market for the treatment of carpets with a Cleaning agents work in the area of the brushes a lower speed than usual care of carpets, especially for vacuuming the latter. This is desirable because when rubbing in the detergent thereby achieving an improved effect becomes.
  • This advantage also in the case of the invention Taking advantage of brush cleaning device is further provided that the replacement brushes with a reduction gear work together. The latter causes one Reduction of the motor speed of the brush cleaning device on the replacement brushes.
  • the replacement brushes at a lower speed than the first, for the usual treatment of carpets suitable brushes, resulting in the advantage already mentioned leads.
  • the reduction gear Planetary gears are.
  • the latter can be in the brush body each replacement brush can be provided. Due to this configuration it is achieved that the The speed of the replacement brushes is preferably about a third up to a quarter of the speed of the first brushes corresponds. In a further embodiment, that the replacement brushes with about double the number of bristles compared to the first brushes. This leads to an improved massage in Detergent in the carpet to be treated.
  • the reduction gear arranged on an outer end face of the replacement brushes are. This has the particular advantage that the brush body of the replacement brush is not basic different from those of the first brushes.
  • the drive power is driven by a drive shaft rotating at engine speed on the reduction gear, preferably a Planetary gear, transmitted, it being provided here that the drive power by means of an inner hollow shaft the replacement brush is transferred.
  • the hollow shaft works in the case of a planetary gear, directly on the one arranged there Sun gear. It is also proposed that the hollow shaft with an output-side planet gear Planetary gear cooperates. With one at the same time fixed ring gear of the planetary gear causes this arrangement a corresponding reduction, preferred 3: 1 to 4: 1, with the same transmission of the Direction of rotation on the replacement brush or on the hollow shaft on the planet gear.
  • On the planet gear is the bristle holder of the replacement brush visible from the outside attached.
  • the replacement brush recorded in a half-shell-shaped sleeve is.
  • the brush cleaning device for treatment of carpets with a detergent the usual treatment, especially for suction of carpets used against the brushes in the half-shell shaped exchange brushes replaced.
  • This is particularly true of the Hygiene is a great advantage because after massaging one Detergent in a carpet and the following Exchange the exchange brushes for the first brushes do not touch the replacement brushes directly is required. Rather, it is the case that the replacement brushes together with the sleeve represent a structural unit, only the sleeve is contacted for replacement becomes.
  • the Sleeve on a freely accessible outside face with a handle, for example in the form of a tab or a bracket.
  • the sleeve also has still advantages in that with an onset an outer surface of the sleeve a partial wall of the suction channel. This will make the one already mentioned Conversion of the suction channel to an outer face achieved by brushing.
  • the suction flow is thus from Area of the brushes kept away, with a simultaneous Vacuuming off the detergent while massaging is counteracted.
  • the end slope of the sleeve causes with another insertion due to the support vertical against an inner surface of the housing Lowering the sleeve together with the replacement brush into one lowest position.
  • the one engaging in the replacement brush Due to the rocker construction, the drive shaft can understand this shift.
  • Through the vertical Moving to the lowest position is a room between the outer surface of the sleeve and the inner surface of the housing created, which only the suction channel represents.
  • the original suction channel which at use of the usual treatment, in particular brushes suitable for vacuuming carpets Including brush room is transformed in this way.
  • the brush room is when using the replacement brushes provided sleeves opposite the suction channel locked. It will also be an embodiment preferred, in the case of two replacement brushes with one each Sleeve are provided and in the installed state lie face to face.
  • the after towards the bottom of the brush cleaning device covered - open sleeve has a passage opening for the replacement brushes, which so is dimensioned so that the width of the opening is smaller than however, the overall diameter of the replacement brush is larger than the diameter of the brush body, or the Bristle-bearing bristle carrier.
  • the exchange brush can thus be removed from the brush cleaning device Do not drop the sleeve out of the latter. For removal the replacement brush must be out of the will Sleeve are removed, the yielding bristles allow removal.
  • Another backup of the Exchange brush inside the sleeve is given by that the replacement brush by engaging a radial Projection in a corresponding recess of the brush body is axially secured in the sleeve.
