Definitions

  • the cleaning device is designed for dry cleaning.
  • the cleaning device with the cleaning cloth attached to it is guided over a floor to be cleaned, with the cleaning cloth picking up dust and smaller particles from the floor to be cleaned.
  • Dust-like soiling can be absorbed into the matrix of the cleaning cloth, with the absorption capacity for such soiling being particularly good if the material of the cleaning cloth is porous, as is the case with nonwoven fabric, for example.
  • One problem with this is that cleaning cloth cannot absorb any coarser particles and these remain on the floor to be cleaned.
  • the reservoir makes it possible to take up larger dirt particles which do not adhere to the cleaning cloth or which cannot be taken up by the cleaning cloth.
  • the cleaning cloth picks up finer dirt such as dust or smaller particles during the cleaning process. Larger particles, on the other hand, are pushed in front of the cleaning cloth during the cleaning process and can be collected as a result.
  • the larger particles can be added to the reservoir.
  • the receiving opening can preferably be embodied as an opening in the wiping plate and/or as an opening which is embodied between the wiping plate and a further element, such as in particular the sweeping device described below.
  • the receiving opening is connected to the reservoir by a channel, for example, so that particles can be conveyed through the receiving opening into the reservoir.
  • the wiping plate is preferably of rectangular design, with the receiving opening being assigned to a narrow side of the wiping plate.
  • the wiping process is preferably carried out over one of the two longitudinal sides, so that during a wiping process a wider strip can be cleaned. Because the receiving opening is assigned to a narrow side, this does not interfere with the wiping process.
  • the receiving opening is only used when larger dirt particles are to be picked up.
  • the cleaning cloth can be looped around the two long sides in this embodiment, which enables the cleaning cloth to be attached in a particularly simple manner and, moreover, a particularly effective cleaning work.
  • fastening means for the cleaning cloth can be provided on the second main side.
  • the fastening means are designed as soft clips. These preferably comprise an elastic material placed over a cavity in which an incision is formed. By pressing the cleaning cloth into the incision, the cleaning cloth can be detachably attached in a simple manner.
  • a sweeping device can be assigned to the receiving opening.
  • the sweeping device facilitates the transport of dirt particles into the reservoir.
  • the sweeping device can have a cleaning lip, a bristle arrangement or the like.
  • the sweeping device may include a slidable body that is slid when the sweeping device is moved between the sweeping position and the rest position is moved.
  • the displaceable body is preferably designed as a movable carriage.
  • the second section can be arranged on the side of the first section facing the narrow side of the wiper plate.
  • the link guide can be designed in such a way that the sweeping device is retracted into the mop plate in the rest position. This can be achieved in that the link guide has a third section of the guide groove, in which the guide groove runs transversely to the plane of the wiper plate.
  • the third section can be arranged on the side of the first section facing away from the narrow side of the mop plate. The third section makes it possible to move the sweeping device towards the wiping plate, so that in the rest position it is partially accommodated in a recess formed in the wiping plate.
  • the sweeping device can have a rotatably mounted sweeping element which, in the sweeping position, makes contact with the floor to be cleaned.
  • the sweeping element can be designed in particular as a rotatable sweeping roller.
  • the sweeping element In the rest position, the sweeping element can be drawn in at least partially into the wiping plate.
  • the sweeping element is arranged in the wiping plate in a particularly space-saving manner, so that the wiping plate can also be moved into areas that are difficult to reach and the wiping plate can also be guided under pieces of furniture, for example.
  • the cleaning cloth can be formed from a textile fabric. Such cleaning cloths are inexpensive and easy to produce. Depending on the design, the cleaning cloth can be designed for single use or for reuse. If the cleaning cloth is designed to be reused, it is advantageously set up so that it can be machine washed. Different materials can be used for the cleaning cloth.
  • the cleaning cloth can contain fibers to absorb dirt well.
  • the cleaning cloth can have a woven or a non-woven structure.
  • the cleaning cloth is preferably made of non-woven fabric. A nonwoven fabric is made up of fibers that are not woven. In this configuration, the cleaning cloth is designed in particular as a single-use cloth and is disposed of after use together with the dirt that has been picked up.
  • FIG. 4 shows the cleaning device from FIG. 3 in a section through the sweeping element
  • FIG. 13 shows a sectional illustration through the sweeping element suspension of the cleaning device from FIG. 1 ; 14 shows a sectional view through the drive wheel suspension of the cleaning device from FIG.
  • a reservoir 6 for receiving dirt particles is assigned to the wiping plate 2 .
  • a recess 12 is made in the wiping plate 2 , the recess 12 opening towards the first main side 3 .
  • the cleaning cloth 5 forms a boundary wall 7 of the reservoir 6 . Because the cleaning cloth 5 is arranged below the wiping plate 2 during the intended use, dirt particles taken up in the reservoir 6 accumulate on the cleaning cloth 5 . After the cleaning cloth 5 has been removed, the dirt particles can be disposed of without loss, for example by folding the cleaning cloth 5 together.
  • a receiving opening 8 is formed in the reservoir 6 , which is arranged in one on the narrow side 10 Edge 9 of the wiper plate 2 opens.
  • the receiving opening 8 is arranged in the area of the edge 9 between the wiping plate 2 and the sweeping device 11 .
  • the sweeping device 11 is also provided with a receiving bevel 26 which opens into a cleaning lip 27 . This allows impurities to be picked up particularly effectively and fed to the reservoir 6 .
  • the cleaning lip 27 faces the floor to be cleaned.
  • the receiving slope 26 and the sweeping element 16 are at least partially congruent, and between sweeping element 16 and receiving slope 26 there is only a narrow gap. The gap finally opens into the receiving opening 8 of the reservoir 6.
  • the sweeping element 16 In the rest position 15, the sweeping element 16 is spaced from the floor to be cleaned. The sweeping element 16 is partially drawn into the mop plate 2 in the rest position 15 .
  • a cover 28 which covers the sweeping device 11 , is arranged on the second main side 4 of the wiping plate 2 .
  • FIG. 2 shows the cleaning device 1 in a perspective view.
  • the sweeping device 11 of the cleaning device 1 is in the rest position 15 and is partially retracted into the wiping plate 2 . If the sweeping device 11 is in the rest position, the cleaning device 1 can be wiped out over the floor to be cleaned.
  • FIGS. 4 and 5 show the cleaning device 1 according to FIG. 3 in section.
  • the section in FIG. 4 is chosen so that the sweeping element 16 can be seen, while in FIG. 5 the section runs through the drive wheel.
  • the pedal 18 is connected via a strut 52 to a holding body 53 which is linearly displaceable in a guide 54 attached to the wiping plate 2 .
  • the guide 54 includes two grooves formed in the wiping plate on either side of the holder body 53 . In this way, the pivoting movement of the pedal 18 is translated into a translational movement of the holding body 53, which can be moved back and forth in the guide 54 by the pedal.
  • the strut 52 is connected to the lever 18 so that it can move about the axis of rotation 55 .
  • On the holding body 53 and one end of the spring element 19 is attached to after Releasing the lock 50 to move the lever 18 away from the mop plate 2 and to bring the sweeping device 11 into the sweeping position 15.
  • the other end of the spring element 19 is attached to the wiping plate 2 .
  • FIG. 6 shows the cleaning device 1 according to FIG. Furthermore, the sweeping element 16 is spaced from the floor to be cleaned.
  • the pedal 18 of the actuating device 17 rests flat against the wiping plate 2 , a recess which is configured congruently with the pedal 18 and into which the pedal 18 is sunk in the rest position 15 being made in the wiping plate 2 .
  • Sweeping device 11 associated with a link guide 61, which is arranged on the mop plate 2.
  • the link guide 61 comprises guide elements 62 arranged on both sides of the displaceable body 60, each with a guide groove 63.
  • Guide cams 64 which are arranged on both sides on the displaceable body 60, engage in the guide grooves 63 (cf. FIG. 8).
  • the link guide 61 is designed in such a way that it enables the sweeping device 11 to be displaced along the wiping plate 2 . This is achieved on the one hand that the
  • the sweeping device 11 has a drive wheel suspension 71 which is arranged on the mop plate 2 so that it can move about a first pivot axis 72 .
  • the sweeping device 11 also includes a sweeping element suspension 73 which is arranged on the wiping plate 2 so as to be movable about a second pivot axis 74 .
  • the first and the second pivot axis 72, 74 are arranged coaxially.
  • the drive wheel suspension 71 includes a spring 75 which biases the drive wheel 24 towards the surface to be cleaned.
  • the sweeping element suspension 73 comprises a spring 76 which biases the sweeping roller 16 towards the surface to be cleaned.
  • the drive wheel suspension 71 and the sweeping element suspension 73 are independent of one another, so that the sweeping element 16 and drive wheel 24 can be pivoted independently of one another about the first or second pivot axis 72, 74.
  • the second sprocket 83 meshes with the sweeping member sprocket 85 provided on the sweeping member 16 .
  • the gear stage 25 achieves a transmission ratio such that the rotational speed of the rotatable sweeping element 16 differs from the rotational speed of the drive wheel 24 .
