Definitions

  • the invention relates to a surface cleaning machine, comprising a cleaning roller holder, at least one cleaning roller which is arranged on the cleaning roller holder, a drive device for rotationally driving the at least one cleaning roller, and a sweeping element which is assigned to the at least one cleaning roller and Cleaning roller feeds sweepings.
  • a cleaning device for cleaning a surface which comprises a rotatable brush.
  • a rubber wiper element is also provided, which is spaced apart from the brush and is attached to an underside of a nozzle housing.
  • a cleaning device with a rotatable brush and a single rubber wiper element is also known.
  • a device for fluid distribution on a brush is known.
  • a method for cleaning or cleaning a preferably smooth surface is known, in which the surface to be cleaned is wiped with a substantially cloth-like wiping element while the dirt is being wiped by the wiping element and then the soiled wiping element is moistened and then the dirt is sucked off the wiping element becomes.
  • the invention has for its object to provide a surface cleaning machine of the type mentioned, with which optimal cleaning results on a surface to be cleaned and in particular a hard surface to be cleaned.
  • the sweeping element is immersed, at least in one cleaning operation, with a front area in a trim of the at least one cleaning roller, a front end of the sweeping element being arranged on the front area.
  • the front end of the sweeping element is then immersed in the trim of the at least one cleaning roller in the cleaning operation.
  • Coarse dirt is fed to the at least one cleaning roller through the sweeping element. This is then carried along by the at least one cleaning roller and can be suctioned off via at least one suction mouth.
  • a sweeping element which is immersed with a front area in the trim of the at least one cleaning roller, a constant adjustment of the sweeping element to a surface to be cleaned is possible. It is thereby ensured that a sweeping edge (as the line of contact of the sweeping element on the surface to be cleaned) can form in the cleaning operation in order to be able to supply coarse dirt to the at least one cleaning roller.
  • a pile depth of the trim is actively used to a certain extent, in order to enable constant adaptation to the surface to be cleaned.
  • the front area is designed to be elastic in such a way that it is immersed in the trim due to the weight of the surface cleaning machine when the surface cleaning machine is set up on a surface to be cleaned with the at least one cleaning roller.
  • the weight of the surface cleaning machine causes an elastic deformation (in particular bending) on the sweeping element and thus immersion in the trim.
  • a safe immersion can thereby be achieved, whereby immersion can also be ensured if the angle of the surface cleaning machine varies with the surface to be cleaned.
  • the front end is at a distance from an outside of the trim in a range between 5 percent and 80 percent based on a thickness of the trim.
  • the sweeping element is formed at least in two parts with a first part and a second part, the second part having a higher elasticity than the first part and the front region being arranged or formed on the second part.
  • a functional separation on the sweeping element can be achieved by a two-part design.
  • the second part can be designed with greater elasticity in order to ensure that the front area is immersed in the trim of the at least one cleaning roller at least in one cleaning operation.
  • the first part is used to hold and position the second part.
  • the first part also serves to guide the flow of fluid to one or more suction mouths.
  • the first part has no elasticity that is functional for the sweeping element.
  • the first part can have an inherent elasticity that is so low that the first part cannot deflect elastically in a normal operating mode.
  • the first part is made of a glass fiber reinforced plastic.
  • the second part has, in particular, a Shore hardness in the range between 70 and 90 in order to enable elastic evasion.
  • the second part is made of an elastomer, for example.
  • the sweeping element is designed such that a sweeping edge is always on the second part in the cleaning operation.
  • the sweeping edge is the contact line with which the sweeping element on the cleansing surface.
  • the design mentioned ensures that the sweeping edge lies against the elastic part of the sweeping element in the cleaning operation.
  • the front area of the sweeping element which in turn forms or is formed on the second part, is immersed in the trim of the at least one cleaning roller. It is thereby achieved that an elastic evasion is possible, and thereby an optimized sweeping effect and entrainment effect of "swept up" coarse dirt by the at least one cleaning roller is possible. This good sweeping effect and entrainment effect is guaranteed for all angular positions of the surface cleaning machine relative to the surface to be cleaned, if this is set up on the surface to be cleaned via the at least one cleaning roller.
  • the second part follows the first part in a circumferential direction and in particular the second part is connected to the first part. This allows a one-piece (but multi-part) sweeping element to be provided, which enables an optimized sweeping result.
  • the first part facing the cleaning roller has a cylindrical outer surface.
  • This cylindrical lateral surface forms a "smooth" flow guiding surface, along which a fluid flow can be passed for suction.
  • the sweeping element is produced by a multi-component injection molding process and in particular a two-component injection molding process.
  • This makes it possible to produce a sweeping element that is multi-part in terms of its functionality, but is designed in one piece.
  • This one-piece sweeping element can be easily fixed to the cleaning roller holder and clipped on there, for example.
  • different material properties can easily be set for the first part and the second part. In particular, different elastic properties can be set.
  • a thickness of the sweeping element tapers towards the front end.
  • the front area is designed such that, at least in one cleaning operation, a distance of an outside of the front area facing the at least one cleaning roller to an axis of rotation of the cleaning roller decreases in at least one section towards the front end. This ensures that the front area of the sweeping element is immersed in the trimmings of the at least one cleaning roller with the advantages described above.
  • the sweeping element has a first area and a second area, which follow one another along an axis of rotation of the sweeping element of the at least one cleaning roller, at least one continuous recess being arranged between the first area and the second area.
  • a shaft of the at least one cleaning roller can, for example, be coupled to a corresponding drive device through the continuous recess. This makes it possible to implement a central drive for the at least one cleaning roller. This in turn provides a high level of edge cleaning capability on both sides for the corresponding surface cleaning machine.
  • the at least one cleaning roller is formed at least in two parts, with a first part which is assigned to the first region of the sweeping element and a second part which is assigned to the second region of the sweeping element, one or more Coupling elements of the drive device, which couple the drive device to the at least one cleaning roller, through which at least one continuous recess is immersed.
  • a surface cleaning machine with a central drive of the at least one cleaning roller can thereby be realized. Then it is not, for example more necessary to store the at least one cleaning roller on the outside. This in turn gives high cleaning performance on both sides, even at edge areas.
  • first region and the second region of the sweeping element are connected via a web.
  • the sweeping element can thereby be formed as one part.
  • a sliding surface can be formed on the web, an associated counter-sliding surface in particular being free of trimmings.
  • the associated counter-sliding surface is arranged, for example, on the at least one cleaning roller or a shaft for the at least one cleaning roller.
  • the front end face is immersed in the trim of the at least one cleaning roller and is not in contact with the surface to be cleaned, and in particular that a sweeping edge, which abuts the surface to be cleaned, is spaced apart from the front end.
  • the sweeping element is fixedly arranged on the cleaning roller holder and in particular is arranged on the cleaning roller holder in a non-displaceable and non-rotatable manner. It is possible for the sweeping element and in particular a portion of the sweeping element to move relative to the cleaning roller holder via an elastic design or elastic partial design of the sweeping element.
  • the sweeping element is arranged to be movable and in particular rotatable on the cleaning roller holder. Due to a rotatable arrangement, the sweeping element as a whole is movable relative to the cleaning roller holder and thus also to the at least one cleaning roller. As a result, a constant distance between the rotating cleaning roller and the sweeping edge can also be achieved regardless of the angular position of the surface cleaning machine relative to the surface to be cleaned, if the at least one cleaning roller is placed on it.
  • the rotatable mobility of the sweeping element allows a corresponding adjustment. It is also advantageous here if a front area of the sweeping element is immersed in the trim of the at least one cleaning roller.
  • the sweeping element facing away from the forward direction covers the at least one cleaning roller to the rear and on the surface to be cleaned over at least a length of at least a cleaning roller is applied.
  • the sweeping edge lies in particular on an elastic region of the sweeping element.
  • a moistening device is provided for the cleaning roller. This allows the rotating cleaning roller to be moistened directly or indirectly.
  • cleaning liquid is applied directly to the at least one cleaning roller.
  • indirect moistening cleaning liquid is applied to the surface to be cleaned and the at least one cleaning roller absorbs liquid from there.
  • the cleaning liquid provided by the moistening device makes it easier to loosen and take away dirt on the surface to be cleaned.
