Definitions

  • the invention relates to a cleaning device, comprising a base body with a roller device and a suction device, the roller device defining a line of movement of the cleaning device, the suction device opening into a suction opening which is arranged on the side of the base body facing the floor to be cleaned
  • the suction opening is delimited by a first wall and a second wall, the first wall and the second wall running transversely to the line of movement, the suction opening being assigned an elastically formed lip which rests on the floor to be cleaned during the intended use of the cleaning device, wherein the lip rests against the first wall during the movement of the cleaning device in a first direction along the line of movement and rests against the second wall in a second direction during the movement of the cleaning device along the line of movement.
  • Such a cleaning device is known from DE 102018 105461 A1.
  • the cleaning device known from the prior art also comprises a roller brush to loosen dirt from the floor to be cleaned and a device for wetting the floor to be cleaned with liquid speed.
  • the device is assigned to the brush roller.
  • the cleaning device enables a combined dry and wet cleaning.
  • the suction opening When moving the cleaning device in the first direction, the suction opening first comes into contact with the dirt lying on the floor to be cleaned. Particulate and dusty dirt is transported through the suction opening and the suction channel into a dirt container. At the same time the floor to be cleaned is wetted by means of the device with a cleaning liquid which dissolves dirt adhering to the floor. This dirt is then removed from the floor to be cleaned by the roller brush.
  • the first direction of movement corresponds to the forward movement of the cleaning device. In the first direction of movement, the lip rests against the first wall so that a gap opens along the front edge in the area of the second wall, through which dirt, in particular particulate pollution, enters the suction channel via the suction opening.
  • the invention is based on the object of further developing the cleaning device in such a way that an improved cleaning performance is made possible.
  • the lip is designed in such a way that the lip rests sealingly against the floor to be cleaned when moving in the second direction of movement and is liquid-permeable when moving in the first direction of movement.
  • the lip when the cleaning device moves forwards, the lip rests on the floor to be cleaned in such a way that particulate contamination can get into the suction opening and that the suction device can have a high suction power, but a liquid lying on the floor is not pushed in front of the lip that when changing the direction of movement, a linear liquid film remains on the floor to be cleaned.
  • the lip rests against the floor to be cleaned in such a way that a film of liquid can be drawn off the floor to be cleaned and finally fed to the suction opening. This enables quick and streak-free drying of the floor to be cleaned.
  • Sealing in the context of the invention does not mean that no liquid is allowed to pass between the lip and the base. Even when moving in the second direction of movement, a film of liquid remains behind the lip on the floor to be cleaned. But this one contains less liquid than the one Liquid film that remains behind the lip when moving in the first direction of movement.
  • a particularly good cleaning result can be achieved because the lip limits the suction opening during the movement in the first direction of movement so that particulate dirt can be well absorbed by the suction device, but a liquid film on the floor does not penetrate too much the lip is peeled off.
  • the lip rests on the floor to be cleaned in such a way that a liquid film lying on the floor is pushed in front of the lip and finally conveyed into the suction opening by means of the suction device. The remaining liquid on the floor to be cleaned dries off by itself.
  • the first direction of movement and the second direction of movement are different from one another.
  • the first direction of movement and the second direction of movement are opposite to one another. It can therefore be a forward movement and a backward movement of the cleaning device.
  • the lip can have a support body and a sealing body, the support body being pivotably arranged in the suction opening and the sealing body being arranged on the edge of the support body facing the floor to be cleaned.
  • the lip has an elastic and a relatively rigid section, the rigid section allowing a defined articulation and the elastic section allowing a good sealing effect.
  • the edge of the sealing body assigned to the floor to be cleaned can be rounded off. This enables a better, linear contact of the lip in the direction of the floor to be cleaned, even if the lip is at least is partially bent.
  • the edge associated with the floor to be cleaned is designed as a quarter circle when viewed in cross section.
  • the lip can be arranged in such a way that the rounding of the quarter circle points in the direction of the first edge.
  • the tip of the quarter-circle contour of the lip comes into contact with the floor to be cleaned.
  • This leads to a high pressure gradient which in turn is associated with a high sealing effect.
  • the lip moves in the first direction of movement, however, the rounded section comes into contact with the floor to be cleaned. This leads to a lower pressure gradient because a liquid film can build up in the gap resulting from the quarter circle section and the floor to be cleaned, which ultimately leads to the lip being lifted off the floor to be cleaned.
  • the lip can have a thickening on the edge associated with the floor to be cleaned.
  • the thickening can be essentially circular. The thickening enables the lip to rest in a line even when the lip is folded down.
  • the support body and the sealing body can be designed in strip form, the sealing body being angled to the support body.
  • the free end of the lip preferably protrudes in the direction of the first wall. Due to the angled sealing body, when moving in the first direction of movement, a film of liquid can in turn build up in a gap between the lip and the floor to be cleaned, which leads to the sealing lip lifting off. If the lip rests against the second wall and the cleaning device moves in the second direction of movement, however, there is a large pressure gradient so that the lip is impermeable to liquid in this direction of movement and pushes a film of liquid in front of it and feeds it to the suction opening.
  • the sealing body can have a recess running at least partially in the longitudinal direction on at least one side.
  • the recess is preferably made on the side of the lip, which is assigned to the first wall.
  • the recess results in a material weakening which increases the elasticity of the lip.
  • the lip is particularly soft in the first direction of movement, so that the liquid film can lift the lip off the floor to be cleaned.
  • the sealing body can be made of elastic plastic and the support body of dimensionally stable plastic.
  • the lip can be designed as a two-component injection-molded element. Such a lip is inexpensive to manufacture.
