Definitions

  • the present invention relates to a cleaning device according to the preamble of claim 1 and a method for cleaning according to the preamble of claim 11.
  • Cleaning devices are known for numerous applications. Particular attention is paid to floor cleaning facilities, which are of different types. These include hand-operated household cleaning devices, such as in the EP 2 387 932 A1 or the DE 20 2009 013 434 U1 shown, and large area cleaning devices, such as in FIG EP 2 343 003 A1 shown.
  • cleaning devices use roller-shaped brushes which are arranged with their axis of rotation parallel to the surface to be cleaned.
  • brush arrangements are also known, especially in connection with large-area cleaning devices, in which plate-shaped brushes are used, the axis of rotation of which is arranged perpendicular to the surface to be cleaned, such as the example DE 12 49 395 A1 , EP 0 367 732 A1 and EP 0 705 558 A1 demonstrate.
  • a cleaning device which has an endless belt and at least one brush body. Two brush bodies rotating in opposite directions work together and create a suction effect that removes dirt and moisture from the surface to be cleaned.
  • the endless belt is intended to remove dirt and moisture, which results in a high cleaning performance overall, but also has a relatively complex structure.
  • the DE 698 03 552 T2 shows a cleaning device in which the endless belt interacts directly with a brush body, so that the brush body loosens or removes dirt and liquid from the endless belt.
  • the dirt and liquid are discharged by a low-pressure suction source, which, however, requires additional energy in addition to driving the endless belt and brush body.
  • the liquid substances are not sufficiently removed from the endless belt.
  • the U.S. 2,601,690 A discloses a cleaning device having a revolving belt and a tank through which the belt runs. Brushes are provided to clean the belt.
  • the US 2003/159223 A1 shows a mop device in which there is a rollable tape and a rotatable brush body.
  • the object of the present invention is to provide a cleaning device which has a simple structure with only low energy consumption, the cleaning performance in particular nevertheless being high.
  • the cleaning device should in particular have a compact design.
  • the inventors have recognized that the set object can be achieved particularly easily if there are means for squeezing liquid out of the endless belt, because a suction device can then be dispensed with, but the liquid is discharged from the endless belt by means of these squeezing out means and if necessary can be dispensed into a collecting container.
  • the cleaning device according to the invention with a housing, at least one endless belt and at least one brush body, the at least one brush body acting on at least one contact against the endless belt to loosen and / or remove dirt from the at least one endless belt, is therefore characterized by means for Expressing liquid from the at least one endless belt.
  • the brush body acting against the endless belt is advantageously set in such a way that, in addition to brushing out dirt, there is also at least partial brushing out of liquid that is present on or in the endless belt. This improves the cleaning and drying of the endless belt. In addition, this can reduce the pressure force of the means to squeeze out, reducing the energy requirement of the Cleaning device can be reduced. As a result, the operating time of the cleaning device can be increased overall for a given battery charge. On the other hand, cable operation can also be provided, for which the energy requirement would then be reduced.
  • the brush body can be adjusted, for example, by adjusting the pressure against the endless belt and / or by using bristles that engage in the endless belt.
  • the speed of the brush body at the contact between the brush body and the endless belt is advantageously higher than the speed of the endless belt at the contact, since dirt and possibly also liquid are then optimally brushed out.
  • the direction of rotation of the at least one endless belt at the contact between the brush body and the endless belt points away from the surface to be cleaned.
  • the pressing-out means preferably have two roller bodies, between which the at least one endless belt is pressed.
  • the extrusion means can then be implemented particularly easily in terms of design.
  • the at least one endless belt and the at least one brush body in the operating state each at least partially rest on the surface to be cleaned, then in contrast to DE 20 2014 001 491 U1 no second brush body is required and the cleaning device has a particularly simple structure.
  • An adjustment option for the endless belt can also be provided such that the angle of inclination of the endless belt with respect to the surface to be cleaned can be adjusted. In this way, on the one hand, the contact pressure on the surface to be cleaned can be set and, on the other hand, also the surface with which the endless belt rests simultaneously on the surface to be cleaned.
  • the pressing-out means are arranged behind the at least one contact between the brush body and the endless belt with respect to the direction of rotation of the at least one endless belt. This ensures that dirt is first removed from the endless belt and not worked into the endless belt by the pressing means, whereby the cleaning performance can be kept very high.
  • the squeezing means are adapted to provide a selectively selectable contact pressure in order to set the humidity of the surface to be cleaned.
  • the squeezing-out means can also be set in such a way that there is no contact pressure in order not to cause any liquid to be squeezed out in certain operating states.
  • the pressing-out means can be designed to be spaced apart from the endless belt.
  • the contact pressure between the endless belt and the brush body can be selectively adjusted, the brush body also being designed to be spaced apart from the endless belt here.
  • means are provided for diverting the pressed liquid away from the at least one endless belt and / or means for diverting the removed dirt away from the at least one endless belt.
  • the dirt or the liquid can then be discharged into a corresponding receptacle in a particularly simple manner, this preferably being designed uniformly as a dirty water collecting container. If the liquid drainage means and the dirt drainage means are designed, in particular, as a unitary component, the cleaning device has a particularly simple construction.
  • These discharge means support the brush body, which may already be transporting liquid and dirt into the receptacle itself.
  • liquid drainage means and / or the dirt drainage means have sealing means opposite the endless belt. This can prevent liquid or contamination from flowing over.
  • the liquid drainage means and / or that the dirt drainage means are designed with at least one drainage surface, the liquid drainage means and / or the dirt drainage means being designed as a diverting plate.
  • the cleaning device is particularly simple in construction.
  • the liquid drainage means and / or the dirt drainage means are arranged between the contact between the brush body and the endless belt and the pressing-out means and / or that the liquid drainage means and / or the dirt drainage means are arranged at a distance from the at least one endless belt.
  • the dirt discharge means have at least partially a contour that is designed to correspond to the contour of the brush body. Then a particularly uniform transport and discharge of contamination is guaranteed.
  • the dirt drainage means are spaced from the outer contour of the brush body in the operating state in the range of 0 mm to 5 mm, in particular in such a way that the dirt drainage means have a self-cleaning effect. Then the maintenance effort is significantly reduced.
  • means are provided for setting the tension of the at least one endless belt, the tension setting means preferably having at least one roller body, the tension setting means including in particular the pressing means. Then can always be a optimal tension maintained or, if necessary, adjusted automatically.
  • the position of the squeezing-out means is changed, the position of the discharge means can also be changed at the same time, in order to ensure optimal positioning of the discharge means with respect to the endless belt.
  • a guide means for example a guide roller, could adjust the endless belt tension so as to be displaceable independently of the extrusion means.
  • a splash guard is arranged above the extrusion means, which preferably rests against the endless belt with sealing means. In this way, splashes of liquid can be prevented when squeezing out. In addition, no dirt particles can be thrown forward out of the cleaning device.
  • a dirt collecting container is provided with a receiving edge which, viewed vertically, is arranged at the level or below the outer contour of the brush body in the operating state. Then the contamination entry is optimized.
  • suction for the dirt and the liquid can also be provided.
  • the cleaning device has a storage area in order to place the cleaning device thereon on a surface, the storage surface being arranged such that the endless belt and the brush body do not touch the surface for the cleaning device placed thereon.
  • the cleaning device can then be stored in a particularly space-saving manner, with optimal drying of the endless belt and brush being ensured at the same time, so that germ contamination is effectively prevented. In this position of the cleaning device, the endless belt and the brush body can also be changed very easily.
  • the endless belt has a drivable base on which a cleaning part rests releasably, wherein the coupling between the base and cleaning part can be produced by bracing the base, whereby the cleaning part is pressed onto the base.
  • the base is advantageously a rubber band.
  • the base preferably has guide means for the drive means of the cleaning device, which run in the drive direction.
  • a cleaning device comprising a housing, at least one endless belt and at least one brush body, with dirt being loosened by the action of the at least one brush body on at least one contact against the endless belt of the at least one endless belt and / or removed, which is characterized in that liquid is pressed out of the at least one endless belt by means for pressing out liquid.

  • the endless belt 16 absorbs this cleaning liquid R and dirt from the surface to be cleaned. So that this works optimally, the endless belt 16 has a special microfiber trim and transports the substances picked up in transport direction A towards the brush body 18.
  • suitable materials such as textiles, brushes, nylon pads or the like, or a combination thereof can be used .
  • the brush body 18 also picks up dirt and liquid and transports them upwards in the direction of rotation B.
  • the opposite direction of rotation A, B of the endless belt 16 and the brush body 18 creates a suction effect S, which supports the removal of dirt and liquid upwards beyond the contact 42.
  • the brush material of the brush body 18 acts against the endless belt 16 and loosens or removes dirt and partly also liquid that has been taken up in the endless belt 16.
  • brush material bristles made of natural or plastic, as well as textile materials in general, microfibre and nylon are very suitable.
  • the speed of rotation of the brush body 18 is preferably set in such a way that the endless belt 16 is overtaken at the contact 42 and this results in a spinning wheel effect.
  • the speed of rotation of the brush body 18 in the contact 42 is thus higher than the transport speed of the endless belt 16.
  • the dirt-liquid mixture D released from the endless belt 16 is conveyed upwards in the direction of the deflector plate 22 by the centrifugal wheel effect, the centrifugal wheel effect being additionally supported by the suction effect S, which causes an upward air flow.
  • This air flow is intensified by a chimney effect which is formed between the endless belt section 44 and the side wall 46 of the dirty water tank 20. Since the air flow wants to relax, it guides the pollution-liquid mixture D into the dirty water container 20.
  • the deflector plate 22 supports this through its inclination towards the dirty water tank 20, so that the dirt-liquid mixture D hitting the deflector plate 22 is diverted into the dirty water tank 20.
  • the deflection plate 22 is arranged without forming a gap and without touching the endless belt 16 in the operating state, so that the contamination-liquid mixture D is largely excluded from the space above the deflection plate 22. This prevents contamination from still being in the endless belt 16 above the deflector plate 22 in the direction of rotation A of the endless belt 16.
  • the liquid F remaining in the endless belt 16 is pressed out of the endless belt 16 and runs over the deflector plate 22 into the dirty water tank 22.

  • the overall operating time of the cleaning device 10 for a given battery charge can be increased. In the case of network operation, this reduces energy consumption.
  • the endless belt section 28 resting on the floor 30 and the brush body 18 provide sufficient guidance for the cleaning device 10 so that additional support wheels or the like can be dispensed with. This allows lanes are largely prevented on the floor 30.
  • the opposite direction of rotation of the brush body 18 compensates for the movement of the endless belt 16 so that the cleaning device 10 can be moved easily.
  • the endless belt 16 is designed as a replaceable element, i. it can be removed from the guide rollers 24, 26, 34.
  • the pressure roller 36 is removed from the guide roller 34 and the guide roller 24 is displaced in the direction of the guide roller 26. If a multi-part endless belt 16 with a base 40 is used, it is also possible to remove only the cleaning part of the endless belt 16.

It is brought close to the endless belt 106, the dirt discharge surface 170 and the liquid discharge surface 172 each acting against the endless belt 106 through sealing elements in the form of flexible sealing lips 174, 176.
  • the sealing element 174 prevents dirt loosened with the brush body 108 from passing over in the direction of the press-out means 126 and water, and the sealing element 176 prevents liquid from flowing past the discharge body 112 parallel to the endless belt 106.
  • the protective deflection surface 170 has a section 178 shaped to correspond to the brush body 108, which is brought so close to the brush body 108 that ideally at least some bristles brush against it, which results in a self-cleaning effect for the dirt deflection surface 170.
  • the dirt and the liquid brushed out of the endless belt 106 by means of the brush body 108 is transferred through the brush body 118 between the receiving edge 166 and discharge body 112 into the dirty water container 110, ie thrown in (see arrow D).
  • excellent conduction takes place by means of the channel formed between dirt discharge surface 170 and brush body 108, which at the same time also transmits the suction effect S, whereby dirt and liquid are carried away. This dirt and the liquid are further transferred into the dirty water tank 110.
  • a splash guard 180 is provided, which extends around the pressure roller 128 above, with a sealing element 182 in the form of a flexible sealing lip likewise located between the splash guard 180 and the endless belt 106.
  • the splash guard 180 prevents the pressure roller 128 from distributing a spray mist in an uncontrolled manner due to its rotation when large amounts of liquid are taken up by the endless belt 106, so that all the liquid that is pressed out is captured via the diverting body 112.
  • the splash guard 180 in connection with the sealing element 182 ensures that no dirt particles are thrown forward out of the cleaning device 100.
  • the cleaning device 100 in contrast to the cleaning device 10, only rests in the area of the front guide roller 114 with the endless belt 106 on the surface 124 to be cleaned.
  • the weight of the cleaning device 100 is distributed in such a way that the brush body 108 bears about 60% of the total weight, while the front guide roller 114 bears about 40% of the total weight.
  • the brush body 108 can optimally provide for a travel direction compensation with respect to the counter-rotating endless belt 106 and moreover achieve very good cleaning results even in joints, in particular with a tiled floor. Due to the high ground pressure by means of the front guide roller 114, the endless belt 106 achieves very good absorption of dirt and liquid.
  • Means are not shown for adjusting the orientation of the endless belt 106 with respect to the surface 124 to be cleaned.
  • the contact surface of the endless belt 106 on the surface 124 to be cleaned and thus the contact pressure on the surface 124 to be cleaned can thus be set in a targeted manner.
  • Such means for adjusting the alignment can include, for example, the rear guide roller 116, which is then designed to be displaceable towards the surface 124 to be cleaned or away from it.
  • the front guide roller 114 could in turn serve to adjust the tension of the endless belt 106.
  • the following cleaning mode can of course also be used for this cleaning device 100 for the cleaning device 10 with light to moderately heavy soiling:
  • the cleaning device 100 is moved forward, the nozzle 130 spraying washing liquor onto the surface 124 to be cleaned.
  • the endless belt 106 wipes over it and picks up dirt and liquid from the surface 124 to be cleaned and transports everything to the brush body 108, the liquid being stored in the endless belt 106.
  • the brush body 108 brushes the dirt out of the endless belt 106 and also the part of the liquid near the surface and transports it into the dirty water container 110 (arrow D).
  • the remaining liquid is squeezed out of the endless belt 106 by means of the squeezing out means 126 and also transferred to the dirty water container 110.
  • the surface 124 to be cleaned is wiped dry with the endless belt 106 by moving backwards and, if necessary, forwards again, and any drops of liquid or traces of the brush body 108 on the surface 124 to be cleaned are removed.
  • This cleaning process can be repeated as required by spraying on the washing liquor again.
  • the liquid When driving forwards and backwards without adding liquid via the nozzle 130, the liquid is absorbed particularly well or the previously wetted is dried Surfaces. When working dry without the addition of liquid, the surfaces are polished, which can be optimized both via the speed of rotation of the brush body 118 and the endless belt 106 and via the choice of material for the endless belt 106 and the brush body 118.
  • a nozzle control in the form of an automatic coupling of the direction of travel and nozzle 130 could advantageously also be provided in such a way that the nozzle 130 is activated when driving forwards, but deactivated when driving backwards, whereby wetting with liquid and simultaneous cleaning occurs when driving forwards and when reversing drive a drying.
  • the present invention provides a cleaning device 10 which is of very simple construction and which can be easily dismantled and assembled for maintenance purposes. Maintenance is improved above all if an endless belt with a base and a cleaning part that can be removed therefrom is used.
  • the cleaning device 10 has a particularly high cleaning performance with only low energy consumption. The consumption of water and cleaning agents is also reduced.
