Definitions

  • the invention relates to a mobile floor cleaning machine with the features the preamble of claim 1.
  • Floor cleaning machines are, for example, as mobile sweeping machines or mobile scrubbers known.
  • a sweeper can as Cleaning tool are used a sweeping roller, which on the zu sweeping floor surface can be placed and lifted from this.
  • the sweeper has at least a second cleaning tool in the form a laterally beyond the outer contour of a chassis protruding disc brush on.
  • a drive motor is used for locomotion the sweeper.
  • the sweeper can in different modes operated, wherein in a first mode, only a locomotion takes place, the sweeping roller and possibly also the disc brush but are arranged at a distance to the bottom surface.
  • the broom In a second mode only the broom can be lowered and activated, but the Disc brush remains in its off position, and in a third Operating mode, in addition to the sweeping roller and the plate brush on the zu sweeping ground surface are lowered and rotated. additionally can be provided that the sweeper has a suction unit, with where the floor surface to be swept can be sucked off.
  • Scrubber driers usually come with at least one scrubbing brush used for scrubbing or polishing on the to be cleaned Floor surface placed and can be lifted off this.
  • Cleaning liquid are sprayed onto the floor surface for Scrubbing the same, or else the dry floor surface is scrubbed by the scrub brush only polished.
  • the scrubber-dryer has in many cases in addition a suction unit for sucking the bottom surface, wherein also a Operating mode may be provided, in which the bottom surface only with cleaning fluid sprayed and then sucked off again, without the scrubbing brush is used.
  • Controls such as buttons, rocker switch and / or joysticks use.
  • Object of the present invention is a mobile floor cleaning device of the type mentioned in such a way that it is a simplified Handling has.
  • a mobile floor cleaning machine of the generic type Art solved in that the controls a main switch for switching the floor cleaning machine on and off, designed as a rotary switch mode selector switch for Selecting a specific operating mode and at least one control for controlling the direction of travel of the floor cleaning machine, wherein the mode selector switch has a plurality of operating positions, the each correspond to a particular mode.
  • the use of a designed as a rotary switch mode selector switch allows the handling of the floor cleaning machine considerably simplify, because their operation, it is only necessary that the User first actuates the main switch and with the help of Steuereiementes the direction of travel, then he can by means of the mode selector switch select the desired mode of operation.
  • the total Operation of the floor cleaning machine can therefore be done with one hand and is very clearly arranged for the user. Based on the desired Operating position recognizes the user readily in which mode the floor cleaning machine is currently operated.
  • the main switch is designed in a preferred embodiment as a key switch.
  • the main switch forms an ignition lock for switching on and off a drive motor of the drive unit.
  • the mode selector switch comprises a knob that is positionable in the operating positions, each operating position being assigned a display field with a display symbol is that corresponding to the selected operating position mode symbolizes, and wherein the knob comprises a display element that in each Operating position points to the respective display symbol.

  • the knob is one by the user grippable knob on which a pointer is formed.
  • a pointer is formed.
  • the Rotary knob allows easy handling of the mode selector, and by means of the molded-on pointer, the user can access the in the relevant operating position relevant indicator symbol are pointed.
  • the pointer and the rotary knob is the position of the mode selector switch haptically detectable by the user, it is therefore not necessary that the user while driving on the control panel of the floor cleaning machine looks. The operation of the floor cleaning machine requires therefore less attention and concentration from the user.
  • This operating position corresponds to a pure driving operation of the floor cleaning machine, for example, to move them from a repository to the place of use, without using a cleaning tool is used.
  • the floor cleaning machine has at least two operating modes Cleaning a floor surface, namely a first mode in which only a first cleaning tool or a plurality of first cleaning tools can be activated, and a second mode, in addition to the at least a first cleaning tool at least one further cleaning tool is activatable.
  • a particularly simple handling is in an advantageous embodiment achieved in that in a first operating position only at least a drive motor of the drive unit can be activated that in a second Operating position, which is located immediately adjacent to the first operating position is, in addition to the drive motor, only at least a first cleaning tool is activated, and that in a third operating position, the the second operating position is arranged immediately adjacent, in addition to the drive motor and the at least one first cleaning tool at least one further cleaning tool can be activated.
  • Such Arrangement has the advantage that the user by turning the mode selector switch from one operating position to another operating position in each case another cleaning tool or another group functional can activate identical cleaning tools.
  • the user can assign a desired by him operating mode can. This gives the user the opportunity to the mode most frequently chosen by him, immediately to arrange next to a mode in which only the at least one Drive motor of the floor cleaning machine is put into operation. Furthermore the user can specify desired cleaning processes by him, by assigning operating modes to each other, in each case for cleaning a particular floor surface or a certain floor area required cleaning tool in addition switched on or off. It can thus be a specific one Cleaning cycle are performed, the mode selector switch gradually during the cleaning process from a first operating position is transferred to a final operating position, so that the rotation of the mode selector switch corresponds to a particular cleaning sequence.
  • operating parameters of Floor cleaning machine manufacturer-side and / or programmable by the user wherein the operating parameters assignable to at least one operating mode are.
  • Such a configuration allows the manufacturer and / or the user to program operating parameters for a particular mode of operation, For example, the distance of the axis of rotation of a sweeping roller of the surface to be cleaned or the contact pressure of a scrubbing brush. It can be provided that the operating modes by the position of the Operating mode selector are fixed, while the individual operating parameters, which are relevant for the respective operating mode, by the user are programmable.
  • the floor cleaning machine has an input device,
  • a keyboard has for input of operating parameters below Assignment of the operating mode selected by the operating mode selector switch.
  • authoritative operating parameters can be such a configuration entered by the user in a simple manner by first selecting the mode selector switch in the operating position positioned, which corresponds to the desired mode of operation, and then can by means of the input device to this mode the favored operating parameters are entered.
  • the floor cleaning machine can be designed as a mobile sweeper be with a first cleaning tool in the form of a on the bottom surface lowered and raised by the floor surface sweeping roller, which is around a Rotary axis aligned parallel to the bottom surface is rotatable.
  • the sweeping roller can be positioned in a rest position, in the it is arranged at a distance to the bottom surface, while a drive motor of the Sweeper for locomotion thereof is activated.
  • the sweeping roller lowered to the floor surface to be cleaned be, while the drive motor remains activated, so that the sweeper to sweep the floor surface along it can.
  • the sweeper at least a second cleaning tool has in the form of an over the outer contour of a chassis of the Sweeper protruding disc brush, which is around a substantially vertical to the bottom surface aligned rotation axis is rotatable.
