Definitions

  • the invention relates to a cleaning device with a handle, a cleaning head and at least one rotatable cleaning roller and a suction channel, which can be subjected to negative pressure by means of a suction pump and through which liquid can be sucked off.
  • Cleaning devices that act as scrubbers/vacuums are known in the art. Such cleaning devices have a suction lip which, after wetting and mechanical processing, scrapes the cleaning liquid off the surface to be cleaned, so that the cleaning liquid can be sucked off.
  • the cleaning process requires that the sequence of the individual cleaning steps is observed. Cleaning fluid must first be supplied in the direction of travel of the cleaning device, then the surface to be cleaned must be mechanically cleaned, for example with the aid of brushes, and then the cleaning fluid and the dirt therein must be sucked off. This process-related order of the cleaning steps has the consequence that conventional cleaning devices, which are designed as scrubbing/vacuum machines, can only be operated in a single direction of movement.
  • the object of the invention is to propose a cleaning device which no longer requires unidirectional operation.
  • the cleaning device comprises a handle and a cleaning head which can be moved on a surface to be cleaned.
  • the cleaning head has at least one rotatable cleaning roller and a first lip element which is arranged adjacent to a first suction channel which can be subjected to negative pressure by means of a suction pump.
  • the cleaning head has a second lip element, which is arranged adjacent to a second suction channel, to which negative pressure can be applied by means of the suction pump.
  • the first lip member and the second lip member are each movable between a raised position and a lowered position.
  • the handle of the cleaning device is pivotable such that in a first position of the handle relative to the cleaning head the first lip element is in the lowered position and the second lip element is in the raised position, and in the second position of the handle relative to the cleaning head the first lip element is in is in the raised position and the second lip member is in the lowered position.
  • the cleaning device according to the invention can thus be operated in such a way that one lip element is lowered in a targeted manner by pivoting the handle, while the other Lip member is in a raised position.
  • the cleaning device according to the invention can be configured such that the lip element arranged at the rear in the direction of movement is in the lowered position, whereby the cleaning liquid can be wiped off the surface to be cleaned after the mechanical cleaning process with the aid of cleaning liquid. In this way, at the end of the cleaning process, the cleaning liquid can be sucked off behind the cleaning device in the direction of travel.
  • the cleaning device comprises a first lever element which is pivoted relative to the cleaning head and is suitable for moving the first lip element from the lowered position to the raised position, and a second lever element which is pivoted relative to the cleaning head and is adapted to move the second lip member from the lowered position to the raised position.
  • the use of levers which raise the lip elements respectively represents a simple technical solution.
  • the lip elements can be spring-loaded into the lowered position, for which only a small spring force is required, since this only has to support gravity.
  • the handle is attached to the cleaning head by means of an articulated lever, and in the first position of the handle the articulated lever is engaged with the second lever element, and in the second position of the handle the articulated lever is engaged with the first lever element.
  • the first lip member in the first position of the handle relative to the cleaning head the first lip member remains in the lowered position because in the first position the toggle of the handle only engages the second lever member which raises the second lip member.
  • the situation is reversed in the second position of the handle relative to the cleaning head.
  • the toggle lever is engaged with the first lever member resulting in the first lip member being in the raised position while the second lip member is in the lowered position since the toggle lever does not actuate the second lever member. In this way it is possible to switch back and forth between the two operating states simply by changing the position of the handle relative to the cleaning head.
  • the first position and the second position of the handle are to be defined in such a way that the lip element arranged at the rear in the direction of travel is automatically lowered and the lip element arranged at the front in the direction of travel is automatically lowered without further action by a user simply by normal operation of the handle when moving the cleaning device back and forth Lip element is raised.
  • the first suction channel is connected to a first suction channel and the second suction channel is connected to a second suction channel.
  • the first suction channel and the second suction channel open into a switching device that is connected to the suction pump.
  • the switching device comprises an actuating element which is designed to close the flow connection to the first suction channel or the second suction channel.
  • the provision of such a switching device has the advantage that the negative pressure can be directed to the first suction channel or the second suction channel.
  • the liquid that flows through the lip element must be sucked off collected, which is in the lowered position.
  • the application of negative pressure to the respective other suction channel adjacent to that lip element which is in the raised position does not make sense, since energy is used unnecessarily.
  • the provision of a switching device with an actuating element that is designed to specifically close the flow connection either to the first suction duct or to the second suction duct thus represents a useful addition to the possibility of using the cleaning device in both directions of travel realized according to the invention.
  • the actuating element In the first position of the handle, the actuating element preferably closes the flow connection to the second suction channel, and in the second position of the handle, the actuating element closes the flow connection to the first suction channel. In this way, suction is only carried out where the lip element is in the lowered position.
  • the first lip element forms a structural unit together with the first suction channel
  • the second lip element forms a second structural unit together with the second suction channel.
  • the lip elements are each moved together with the associated suction channel between the lowered position and the raised position.
  • the suction channels can be designed in such a way that they extend almost to the surface to be cleaned, as a result of which the cleaning liquid can be sucked off even at a lower negative pressure.
  • the design as a structural unit has the advantage that the lip element can delimit the suction channel on one side.
  • the handle is preferably in operative connection with the actuating element of the switching device and is Pivoting the handle movable between the first position and the second position.
  • the user thus operates the cleaning device in both directions of movement only via the handle that can be pivoted relative to the cleaning head, the operation differing with regard to the position of the handle relative to the cleaning head.
  • the lip element arranged at the rear in the direction of movement is brought into the lowered position
  • the lip element arranged at the front in the direction of movement is brought into the raised position
  • only the suction channel arranged at the rear in the direction of movement is subjected to negative pressure.
  • the operative connection between the handle and the actuating element of the switching device comprises an articulated lever, which converts pivoting of the handle into a rotary movement of the actuating element.
  • This operative connection represents a simple and maintenance-free possibility for coupling pivoting of the actuating element to pivoting of the handle relative to the cleaning head.
  • the cleaning device comprises two cleaning rollers parallel to one another between the first suction channel and the second suction channel. Both cleaning rollers can be driven during operation, or only one of the two cleaning rollers. It makes sense if the user can choose to run just one or both cleaning rollers. In the case of heavy soiling, it makes sense to use both cleaning rollers, which, however, means increased energy consumption. It is also possible to automatically actuate only one of the cleaning rollers, for example the cleaning roller arranged at the rear in the direction of travel. Included the first lever element and the second lever element can actuate an electrical contact which transmits the drive energy according to the position of the first lever element and the second lever element only to the drive device for the corresponding cleaning roller.
  • the cleaning rollers preferably include cleaning brushes, which have proven themselves for an intensive mechanical detachment of dirt on the surface to be cleaned.
  • the device preferably has a reservoir for cleaning liquid and nozzles for dispensing the cleaning liquid in the direction of the surface to be cleaned and/or in the direction of the at least one cleaning roller. This measure also serves to automate the cleaning process as far as possible. When the device is in operation, cleaning liquid is automatically dispensed with the aid of nozzles, and wetting the cleaning rollers has proven to be a very efficient method of effectively cleaning the surface to be cleaned.
  • the device also has an energy store for wireless operation of the cleaning device, wherein the suction pump can be driven via an electric motor for driving the at least one cleaning roller using energy in the energy store.
  • the cordless operation of the cleaning device has advantages in the efficient cleaning of larger areas, for example in the form of a large number of individual rooms, without the cleaning device having to be unplugged between the rooms and plugged in again in a different socket.
  • the use of an energy store for wireless operation of the cleaning device is particularly suitable in connection with the switching device, by means of which only the suction channel arranged at the rear in the direction of travel is subjected to negative pressure. In this way one can Suction pump are used with lower power consumption and the service life of the energy storage can be extended, whereby the weight of the energy storage and the suction pump can be reduced.
  • the cleaning device is described below as if it were in the operating position when cleaning a flat and horizontal surface to be cleaned.
  • the cleaning device 10 comprises a cleaning head 12 and a handle 14, which is articulated to the cleaning head 12 and has an actuating handle 15.
