Definitions

  • the invention relates to a wet cleaning device, in particular a wet wiping device, with a cleaning roller mounted rotatably about a roller axis and a roller cover which at least partially surrounds the cleaning roller in the circumferential direction and which has at least one displaceable cover element for optionally closing and / or releasing an opening area of the roller cover.
  • the invention relates to a method for operating a wet cleaning device, wherein a rotatable cleaning roller for a regeneration operation of the cleaning roller is shifted away from a surface to be cleaned and is at least partially surrounded by a roller cover.
  • the DE 102 29 611 B3 discloses, for example, a wet cleaning device with a wiper body which can be driven to rotate about an axis of rotation, in which a cleaning liquid is removed from a storage tank and sprayed onto the surface of the wiper body by means of spray nozzles arranged in the direction of the axis of rotation of the wiper body.
  • the wiping body thus moistened is guided over a surface to be cleaned during a wiping operation, the wiping body taking up dirt from the surface to be cleaned.
  • the wiping body is increasingly covered with dirt, so that regeneration is necessary.
  • the wiper body is lifted off the surface to be cleaned, surrounded with a housing and sprayed with unused cleaning fluid.
  • the wiper body rotates so that cleaning fluid and dirt are expelled from the wiper body, hit the inside of the housing and are transferred to a receiving tank.
  • the wiper body is lifted off the surface to be cleaned manually by a user of the wet cleaning device.
  • the housing is also manually guided around the wiper body. This is uncomfortable because the user of the wet cleaning device has to carry out at least two manual steps. It can happen that the user forgets to surround the wiper body with the housing, so that cleaning liquid can splash into the environment during regeneration operation of the wiper body.
  • the displaceable cover element of the roller cover is coupled to the cleaning roller via a gear, in particular a toothed gear, in such a way that the cleaning roller is moved by moving the cover element is displaceable or the cover element can be displaced by moving the cleaning roller.
  • the displacement of the cover element and the displacement of the cleaning roller are now coupled such that displacement of the cover element simultaneously causes displacement of the cleaning roller and that displacement of the cleaning roller simultaneously results in displacement of the cover element.
  • a user for example, will fail to move the cover element before a regeneration operation and that cleaning fluid will escape to the outside. It also prevents the cover element from bumping against the cleaning roller during displacement and / or forgetting to lift the cleaning roller off the surface.
  • the cover element when the cleaning roller is moved, the cover element is automatically moved, and vice versa. The user therefore has to either move only the cover element or only the cleaning roller, as a result of which the cleaning roller or the cover element is then automatically moved.
  • the displacement of the cover element or the cleaning roller is preferably triggered by actuating a corresponding switch on the wet cleaning device.
  • manual shifting of the cover element or the cleaning roller is alternatively also possible.
  • a gear is arranged in a mechanical operative connection between the cover element and the cleaning roller, which transmits a displacement movement of the covering element or the cleaning roller to the cleaning roller or the covering element.
  • the transmission can be particularly advantageously a toothed transmission with a plurality of toothed transmission elements, such as, for example, toothed wheels and / or toothed racks.
  • the gearbox can be single-stage or multi-stage. In particular, a transmission is conceivable when transferring energy from the cover element to the cleaning roller or vice versa, which reduces the force to be applied for the displacement.
  • the cover element is displaceable in the circumferential direction of the cleaning roller about a cover axis, in particular is rotatable about the roller axis.
  • the roller cover is formed in the circumferential direction of the cleaning roller and thereby covers at least a partial peripheral region of the cleaning roller.
  • the covering element can advantageously be displaced, in particular rotatable, about the covering axis to complete the roller covering, so that as the displacement progresses, an opening area of the roller covering is closed or opened. It is particularly advantageous if the cover axis is equal to the roller axis. In this case there is a common axis around which both the cleaning roller and the cover element rotate. This ensures that the rotational paths of the cover element and the cleaning roller do not cross and lead to a collision.
  • the roller axis be arranged on a pivot arm which is pivotably mounted about a pivot axis on a housing of the damp cleaning device.
  • the displacement of the roller axis that is to say the lifting of the cleaning roller, can in principle be carried out by means of a linear movement or by means of a pivoting movement, the pivoting of the roller axis along a curved path preferably being proposed here.
  • the wet cleaning device has a swivel arm which is mounted on a swivel axis on the housing of the wet cleaning device.
  • the swivel arm carries the roller axis, which is preferably oriented parallel to the swivel axis and which thus swivels the swivel arm is displaced along a circular path around the swivel axis of the swivel arm.
  • a lever can be varied which determines the force required for shifting the roller axis.
  • the transmission be at least partially arranged on the swivel arm.
  • the swivel arm thus carries, for example, one of several transmission elements of the transmission, so that a displacement of the swivel arm simultaneously leads to a drive of the transmission elements.
  • the displacement of the swivel arm can simultaneously cause the cleaning roller and the covering element to be displaced.
  • the cover element has a first gear element and the housing of the wet cleaning device has a second gear element.
  • One of the gear elements is preferably arranged to be movable and the other gear element is immovable.
  • the housing of the wet cleaning device can have a toothing in the manner of a toothed rack, and the cover element can have a corresponding partial area, which can be formed in the manner of a rotatable gearwheel, which leads to rotation of the cover element when it is displaced along the toothed rack. This rotation enables the opening area of the roller cover to be closed or opened.
  • At least the housing of the wet cleaning device always has a gear element which is immovable relative to the housing and which serves as a counter bearing for the other gear elements.
  • one of the movable gear elements it is also possible for one of the movable gear elements to be driven by means of a drive.
  • the first gear element engage in the second gear element, the swivel arm having a cover axis, in particular the roller axis, on which the cover element is rotatably mounted.
  • This variant describes a one-stage construction of the transmission, in which the torque is transmitted directly from the first transmission element to the second transmission element, or vice versa, without the interposition of further transmission elements.
  • an axis which is advantageously oriented parallel to the pivot axis of the pivot arm and which simultaneously represents the cover axis and the roller axis is formed on the pivot arm.
  • Swiveling the swivel arm causes the cover axis and the cover element to be displaced, the cover element carrying the first gear element interacting with the second gear element which is fixed on the housing of the damp cleaning device. This causes the cover element to shift into the opening area of the roller cover. Since the cover axis is preferably the roller axis at the same time, there is also a displacement of the roller axis and thus a lifting of the cleaning roller from the surface to be cleaned.
  • a third gear element in particular a gear
  • the gear furthermore have a fourth gear element, in particular a gear, connected to the third gear element in a force-transmitting manner , which engages in the first gear element.
  • This variant uses a multi-stage gear, with a total of four gear elements.
  • two of the gear elements, namely the third gear element and the fourth gear element can be designed as gear wheels and the first and second gear elements can be designed as toothed racks that are immovable relative to the cover element or the housing (for example, as partial areas of the cover element / housing).
  • the first and the second gear element thus do not mesh directly with one another, it is possible to achieve a translation or reduction under the choice of the other gear elements during the transmission of power from the first to the second gear element, or vice versa.
  • the third gear element can thus rotate relative to the second gear element of the housing, which at the same time causes the fourth gear element to rotate, which in turn displaces the cover element relative to the roller cover.
  • a drive is assigned to the swivel axis of the swivel arm or one of the gear elements.
  • the drive is preferably an electric motor, but can also be a drive operated manually by a user of the wet cleaning device or the like.
  • lifting magnets, compressed air-dependent air bellows and the like are also suitable.
  • at least one of the movable gear elements or the swivel arm can be driven, the movement being transmitted to the other gear elements via the gear.
  • the housing have a first guide link, in which an engagement element arranged on the cover element engages.
  • the displacement of the cover element relative to the housing of the wet cleaning device can be carried out in such a way that the cover element does not touch the surface to be cleaned when the cover element is moved into the opening region of the roller cover.
  • This configuration is particularly useful if the cover element is directly associated with an actively driven gear element.
  • the drive causes the cover element to rotate, the shape and position of the guide link on the housing causing the displacement of the cover element relative to the housing.
  • the guide link can thus predefine a displacement path of the cover element which does not lead to the cover element coming into contact, for example, with a surface to be cleaned.
  • the guide link is preferably designed in such a way that the cover element is held so far within the housing during the entire displacement movement that it cannot be pivoted beyond the circumference of the housing and / or over any spacing elements that may be present.
  • the cover element have a second guide link, in which an engagement element arranged on the housing engages.
  • a double link control for the displacements of the cover element and the cleaning roller can thus be formed.
  • dead points are overcome within the guiding backdrop, at which the internal forces which are to be applied for a relocation can go towards infinity and lead to a standstill of the relocation movement.
  • the second management backdrop dead spots are avoided by relocating the managers to the second management backdrop.
  • the roller cover has at least one air passage opening, advantageously one air passage opening each has at end regions lying opposite in the longitudinal extent of the roller cover, and particularly preferably in combination with a further air passage opening in a central region of the roller cover.
  • Such an arrangement directs an air flow at the end regions through the air passage openings into the roller cover along the longitudinal extent of the cleaning roller to the central air passage opening, where the air can finally leave the roller cover again.
  • a method for operating a wet cleaning device in particular such a previously explained wet cleaning device, is also proposed, wherein a rotatable cleaning roller for regeneration operation of the cleaning roller is shifted away from a surface to be cleaned and is at least partially surrounded by a roller cover, wherein the cleaning roller is displaced by displacing a cover element of the roller cover or the cover element is displaced by displacing the cleaning roller, in particular by means of a transmission providing an operative connection between the cover element and the cleaning roller.
  • a displacement of the cover element or the cleaning roller is either possible manually by the user or by means of a drive which the user actuates, for example, via a switch.
  • wet cleaning devices are to be understood as all those devices which can exclusively or, among other things, carry out wet cleaning. These include, on the one hand, the hand-held and automatically movable wet cleaning devices, in particular also cleaning robots, and, on the other hand, combined dry and wet cleaning devices, which can carry out both wet cleaning and dry cleaning. In addition to conventional floor cleaning devices for cleaning a floor, this also means wet cleaning devices for cleaning surface areas in the sense of the invention. These include, for example, devices for cleaning windows and the like.
  • FIG. 1 shows a wet cleaning device 1, which is designed here as a wet wiping device with a basic device 20 and an attachment device 21.
  • a handle 23 is arranged on the base device 20 with a handle 24, by means of which a user can guide the wet cleaning device 1 over a surface to be cleaned.

  • the user moves the wet cleaning device 1 back and forth across the surface to be cleaned, alternately pushing the wet cleaning device 1 away from him and pulling it towards himself.
  • the attachment 21 has a housing 10 in which a tank (not shown) for cleaning liquid is arranged. Cleaning liquid can be poured into the tank via a filler neck 22. Furthermore, a cleaning roller 2 is arranged in the housing 10 and can be rotated about a roller axis 3. The roller axis 3 is essentially perpendicular to a usual direction of movement of the wet cleaning device 1. The cleaning liquid can be dispensed from the tank onto the surface of the cleaning roller 2 in order to moisten it.
  • the cleaning roller 2 rotates about the roller axis 3, so that the peripheral surface of the cleaning roller 2 continuously rolls on the surface to be cleaned.
  • the cleaning roller 2 is usually wrapped with a cleaning covering, possibly with the interposition of an additional liquid-storing sponge body.
  • the cleaning surface here is, for example, a textile cleaning cloth.
  • dirt accumulates continuously on the cleaning roller 2, ie the cleaning covering. Therefore, a regeneration of the cleaning roller 2 may be necessary after a certain operating time, dirt and contaminated liquid being removed from the cleaning roller 2 during a regeneration operation.
  • the cleaning roller 2 is usually rotated at a speed which is higher than the speed of the cleaning roller 2 during a wiping operation. This causes dirt and liquid contaminated with dirt to be thrown off the cleaning roller 2.
  • the sprayed liquid can be collected and fed to a collection container.
  • Figure 2 shows a portion of the housing 10 of the attachment 21, in which the cleaning roller 2 is held rotatable about the roller axis 3.

  • the roller cover 4 has air passage openings 25, one of which is arranged in each case at end regions opposite the longitudinal extent of the roller cover 4, and one in a medium length region of the roller cover 4.
  • the air passage openings 25 serve for the entry and exit of ambient air into the roller cover 4.
  • a gear 7, which has a total of four gear elements 11, 12, 13, 14, is assigned to the end region of the pivot arm 15 opposite the pivot axis 9.

  • the gear elements 13 and 14 can be seen as gears.
  • the gear elements 11, 12, 13, 14, which are in operative connection with one another, have mutually corresponding toothing.
  • the pivot arm 15 is pivoted about the pivot axis 9, namely in one direction into the housing 10, ie with respect to a normal position of the wet cleaning device 1 on the surface to be cleaned from the surface to be cleaned away.
  • the swiveling movement of the swivel arm 15 can either be initiated manually by a user of the wet cleaning device 1, for example by pressing a button, or automatically by a control of the wet cleaning device 1, which automatically initiates a regeneration operation when the cleaning roller 2 is covered with dirt as determined by sensors.
  • An electric motor is preferably assigned to the swivel arm 15.
  • pivoting can also take place by manual intervention by the user, for example also by gripping and pivoting the swivel arm 15.

Then the cleaning roller 2 is greatly accelerated, possibly with the previous or simultaneous addition of liquid. Due to the high speed of the cleaning roller 2, which should be higher than during a wiping operation, the liquid including dirt is thrown out of the cleaning roller 2.
  • a stripping device can be provided which touches the surface of the cleaning roller 2 and additionally supports the regeneration.
  • the rotation of the cleaning roller 2 simultaneously causes a flow of the ambient air, as a result of which air flows into the roller cover 4 through the air passage openings 25 arranged at the end on the roller cover 4, propagates along the longitudinal extent of the cleaning roller 2 up to one in a central region of the longitudinal extent of the roller cover 4 arranged further air passage opening 25.
