Definitions

  • the invention relates to a cleaning device for wet cleaning of a surface with a housing, with a drive means having a drive axle and with a carrier element, the drive means being set up to move the carrier element relative to the housing.
  • the invention further relates to a method for wet cleaning a surface and a control device for a cleaning device for wet cleaning a surface.
  • Various devices are known for wet cleaning of a surface. These include, for example, attachments with a connecting piece that is intended for installation on a basic device with a main unit, for example for an upright vacuum cleaner, and mopping robots that drive autonomously over a floor surface.
  • the holding element can serve as a structural holder for a removable, possibly washable, cleaning element made of textile or fleece, and the cleaning element is preferably intended for moistening with a cleaning liquid.
  • a liquid source for example a water tank, is usually provided on the cleaning device for moistening.
  • the cleaning element can be moistened by hand. In general, the moistened cleaning element is rubbed against the surface to be cleaned by moving the oscillating plate, thus wiping the surface.
  • This configuration can be used for attachments as well as for mopping robots.
  • a drive means is provided, which often has at least one eccentric element.
  • the forces that are brought about by driving the support element can be used for a Attachment designed cleaning device acts against a direction of travel manually specified by a user on the basic device.
  • the movement of the carrier element is an oscillating movement, this can lead to a relatively strong, undesirable deflection from the predetermined direction of travel.
  • the cleaning device is designed as a wiping robot, the drive of the carrier element can lead to undesirable distractions from the actual direction of travel.
  • the cleaning device can alternatively be a module that can be coupled to a cleaning robot or to an attachment for a vacuum cleaner.
  • the present invention is based on the task of improving known cleaning devices and, in particular, increasing the user-friendliness and the quality of the cleaning results when wet cleaning.
  • a cleaning device for wet cleaning of a surface with a housing with a drive means having a drive axle and with a carrier element, the drive means being set up to move the carrier element relative to the housing, in that the drive axle is separated from a first, The angular position defined in relation to the housing can be moved into a further angular position that is inclined by an angle relative to the first angular position.
  • the mechanical force state of the cleaning device can be influenced by adjusting the angular position of the drive axis.
  • disruptive forces that act against a given direction of travel can be compensated for and thus also increase the user-friendliness of a cleaning device designed as an attachment.
  • the direction of travel for an autonomous cleaning device can be adjusted by adjusting the inclination of the drive axle.
  • the drive means can have an electric motor.
  • the drive axis corresponds to the main direction of extension of a connecting element between a motor of the drive means and the carrier element.
  • the drive means has an eccentric element which is connected to the carrier element via a connecting element, the connecting element corresponding to the drive axle.
  • the carrier element is preferably provided for a detachable connection to a holding element, the holding element being designed to accommodate a cleaning element intended for wet cleaning, for example in the form of a microfiber cloth or a mop.
  • a movement of the carrier element causes a movement of the holding element and the cleaning element.
  • the carrier element is, in an operating position of the cleaning device, preferably arranged between the housing of the cleaning device and a surface to be cleaned.
  • the carrier element viewed in plan view, can be covered by the housing and/or at least partially displaced laterally relative to the housing.
  • the carrier element can be provided as a plate which is moved, in particular swung, relative to the housing of the cleaning device by means of the drive means.
  • the movement of the carrier element takes place essentially parallel to a surface to be cleaned. This allows the surface to be cleaned to be wiped across the entire surface.
  • the drive axle By moving the drive axle from the first angular position to the further angular position, the drive axle is tilted. The tilting is even greater because the angular difference between the first angular position and the further angular position is large.
  • the first angular position is defined in relation to the housing.
  • the first angular position and the further angular position are of the drive axle is defined by values in a coordinate system that is fixed relative to the housing during a cleaning process.
  • a displacement of the drive axle from the first angular position into the further angular position is preferably effected by rotating the drive axle about a rotation axis aligned perpendicular to the main direction of extension of the drive axle.
  • At least one weight element is provided for balancing forces that are caused by a movement of the carrier element relative to the housing and which act on the housing, and the at least one weight element is designed such that the displacement of the drive axis of the first angular position causes the at least one weight element to be displaced into the further angular position by a corresponding angle.
  • the at least one weight element is preferably arranged in the housing.
  • the at least one weight element can be connected electronically and/or mechanically to the drive means in order to coordinate its displacement with the displacement of the drive axle.
  • At least one storage element is arranged between the carrier element and the housing and the at least one storage element is displaceable from a first angular position defined with respect to the housing into a further angular position inclined by an angle relative to the first angular position.
  • the angle between the first angular position and the further angular position of the at least one bearing element corresponds to the angle between the first angular position and the further angular position of the drive axle.
  • the at least one bearing element is preferably designed to connect the carrier element relative to the housing and at the same time to allow a movement caused by the drive means or not to counteract such a movement.
  • a control device is provided and the control device is set up to cause the drive shaft and/or the at least one storage element to be displaced from the respective first angular position to the respective further angular position, the angle being from a direction of travel in which the cleaning device is to be controlled depends on.
  • the movement of the cleaning device can be influenced in a targeted manner depending on information that the control device derives, for example from a preset timetable or from a detection of the environment around the cleaning device.
  • a driving direction specified by a user can be automatically supported, for example in the manner of power steering.
  • the carrier element is mounted with the drive axle in such a way that when the drive axle is moved an angle during a wet cleaning process, the carrier element remains essentially parallel to a surface to be cleaned.
  • the drive means can in particular have an electric motor and at least one eccentric, the eccentric being designed for connection to the carrier element via a connecting element designed as a bolt with a ball head.
  • the carrier element can have a receptacle for a ball connection to the bolt. This means that an oscillating movement of the support element can be achieved even when the drive axle is tilted.
  • the at least one eccentric can be rotated in a position that is inclined relative to the surface to be cleaned and/or relative to the housing of the cleaning device, which creates a force that drives the cleaning device over the surface to be cleaned or influences its movement.
  • the carrier element can remain essentially parallel to the surface to be cleaned despite tilting or tilting of the drive axle and a surface can be cleaned evenly.
  • the drive axle is preferably pivotally mounted with the carrier element.
  • the drive axle can be designed to be extendable along its main direction of extension, for example telescopic. An increase in the distance between the drive means and the carrier plate, which causes the drive axle to tilt, can thus be compensated for.
  • a connection piece for a connection to a basic device is provided on the housing.
  • the cleaning device can therefore be designed as an attachment with increased ease of use.
  • disruptive forces from an oscillating movement of the carrier element can be automatically compensated for and, if necessary, movement in a direction of travel specified manually on the basic device can be automatically supported.
  • the drive means is designed as the main drive means for autonomous driving of the cleaning device.
  • a so-called drift or the forces that arise from tilting the drive axle and act on the housing can be used to move the cleaning device designed as a cleaning robot.
  • an additional drive system such as an electric motor coupled to wheels, can therefore be dispensed with.
  • the cleaning device according to this embodiment can be designed without wheels or other aids for moving over a surface to be cleaned. Overall, lanes can be avoided with such an autonomous cleaning device.
  • the cleaning device can have at least two support elements, each of which is driven by a drive means with a tiltable or pivotable drive axle.
  • a drive means with a tiltable or pivotable drive axle.
  • a method for wet cleaning of a surface in which a cleaning device for wet cleaning with a housing, with a drive means having a drive axle and with a carrier element, in particular a cleaning device for autonomous wet cleaning according to one of the previous embodiments provided is, in which the carrier element is driven by the drive means, in which a movement of the cleaning device is influenced by displacing the drive axle from a first angular position defined with respect to the housing into a further angular position inclined by an angle relative to the first angular position.
  • This method has the same advantages as the cleaning device according to the invention.
  • this method can achieve an improved cleaning result and avoid lanes or heterogeneous cleaning zones.
  • the displacement of the drive axle from the first angular position to the further angular position is brought about by actively displacing at least one bearing element which is arranged between the carrier element and the housing.
  • the drive axle can thus be pivotally mounted and its displacement or tilting can be effected by tilting bearing elements.
  • the drive axle or the drive means can therefore be designed to be relatively simple.
  • a travel direction in which the cleaning device is to be moved is set by moving the drive axle and/or the at least one bearing element.
  • This embodiment is particularly advantageous for designing the cleaning device as a cleaning robot, because the cleaning device can then only be moved overall using the drive means already present for the movement of the at least one carrier element.
  • the direction of travel is preferably a preset direction or one determined by a control device in which the cleaning device should travel.
  • the direction of travel can be relative under the form of a direction in a coordinate system to the housing of the cleaning device or relative to the environment of the cleaning device.
