Definitions

  • the invention relates to a cleaning device, comprising a base body, a suction device with a mammal opening and a suction channel and a brush assembly with a rotatable brush roller, wherein the mammal opening and the brush roller are arranged in the base body, that they face the floor to be cleaned, wherein the Mammal opening one of the front edge of the main body facing the first wall and one of
  • Brush roller facing the second wall, wherein the brush roller is adapted to solve soiling of the soil to be cleaned, further comprising means for wetting the floor to be cleaned with liquid, which is associated with the brush roller.
  • Such a cleaning device is known from CN 205126117 U.
  • the cleaning device allows a combined dry and damp cleaning.
  • the infant opening When moving the cleaning device in one direction, the infant opening initially comes into contact with the contaminants resting on the floor to be cleaned. Particulate and dusty dirt are conveyed through the mammal opening and the suction channel into a dirt container. At the same time, the floor to be cleaned is wetted by the device with a cleaning liquid which adheres to the floor
  • the mammal opening is bounded along the longitudinal edge by two lips which project in the direction of the floor to be cleaned.
  • the lips are required to maintain the necessary suction pressure to draw in particulate and liquid contaminants.
  • the cross-sectional width of the mammal opening is limited and thereby larger particles can not be absorbed by the mammal opening.
  • the sealing lip assigned to the front further pushes parts of the particulate contaminants, such as a plow blade of a snowplough, forward in the forward movement so that they do not enter the suction channel.
  • the sealing lip assigned to the brush roller can push a part of the liquid to be absorbed in front of it so that it can not enter the suction channel in the rearward movement either.
  • the invention has for its object to provide a cleaning device, which improves the uptake particulate and moister
  • a lip is pivotable
  • the alternate application of the lip to the first wall or the second wall is preferably carried out as a function of the direction of movement of the cleaning device. If the cleaning device in one direction, for example moved forward, the lip is applied to the brush roller facing the second wall, so that along the
  • Leading edge in the region of the first wall opens a gap through which dirt, in particular particulate contamination passes through the mammal opening into the suction channel.
  • the lip rests against the first wall, so that a gap opens in the region of the second wall, through which the dirt dissolved by the brush roller and the liquid applied by the device pass into the suction channel.
  • the fact that the lip is pivotally arranged in the base body, on the one hand in the region of the front edge, a larger cross section for the mammalian opening can be provided. This allows them to absorb larger particles.
  • the lip functions as a lancing lip and pushes the liquid in front of it so that it is picked up by the mammal opening.
  • the lip is preferably on the floor to be cleaned. This ensures that the lip can pivot depending on the direction of movement of the cleaning device. Furthermore, in particular the suction performance of the infant opening improves.
  • the lip may be shaped as a rocker arm and pivotable in the
  • the lip along a longitudinal edge may have a thickening, which is arranged in a congruent recess of the base body.
  • the recess may be associated with a V-shaped slot through which the lip protrudes. This forms an undercut, which fixes the lip in the body.
  • the V-shaped slot results in the
  • the lip is turned obliquely when the lip rests against the second wall and perpendicular to the to be cleaned
  • Floor is made when the lip rests against the first wall.
  • the lip is biased on the floor to be cleaned when the lip abuts the first wall. This increases the cleaning performance against liquids. If the lip is against the second wall, the preload is lower, so that the maneuvering of the cleaning device is simplified.
  • the lip can be provided with at least one opening.
  • the lip can be arranged in the suction channel so that it is arranged between the suction channel and the mammalian opening.
  • the opening may be shaped in the form of a slot or in the form of several round or square openings. If the lip is against the first wall, there is no air flow through the at least one opening.
  • the lip may have an elastic portion.
  • the elastic portion is preferably associated with the soil to be cleaned.
  • the lip comprises a rigid portion and an elastic portion.
  • the second gap which is delimited by the second wall and the floor to be cleaned, preferably has a smaller cross-section than that of the first wall and the one due to the smaller gap dimension
  • the resulting constriction of the flow cross-section in the region of the second gap increases the suction pressure, which improves the absorption of moist contaminants, which usually have a higher density.
  • the limited by the first wall and the floor to be cleaned first gap accordingly has a larger gap.
  • Gap can particulate pollutions, especially larger particles are better absorbed.
  • the lip may be made of injection moldable plastic, wherein the rigid and the elastic portion are produced in the two-component injection molding and the elastic portion consists of thermoplastic elastomer.
  • the rigid section consists of a dimensionally stable plastic and allows a defined function of the lip.
  • the lip may have at least one, preferably a plurality of spacers, along the edge associated with the floor to be cleaned.
  • Spacers are designed and arranged on the lip that they come in the forward movement of the cleaning device in contact with the soil to be cleaned and cause between the soil to be cleaned associated edge of the lip and the floor to be cleaned creates a narrow gap, on which the suction pressure acts.
  • the device for wetting the floor to be cleaned with liquid can be designed as a dripping device.
  • the device may be designed as a spray device.
  • the device is designed to apply cleaning liquid dripping or in the case of the spray device as a spray on the floor to be cleaned.
  • the device can be arranged between the brush roller and the infant opening. As a result, the cleaning fluid in the immediate vicinity of
  • the brush roller may have peripherally a soft pile formed, for example, microfibers. Alternatively, soft or hard bristles may be used.
  • the suction channel can be operatively connected to a suction fan.
  • Suction fan is preferably operatively connected to an electric motor. This can be supplied via a network connection or via an accumulator with electrical power.
