  • the cleaning unit is brought into the cleaning position in which it is arranged directly above or on the surface to be cleaned. If the floor cleaning machine is moved without the cleaned surface to be cleaned, then the cleaning unit with the lifting device in the rest position raised. In the rest position, the cleaning unit is spaced from the surface to be cleaned or run over and does not come into contact with it.
  • liquid to the cleaning unit In various types of floor cleaning machines, it is desirable to supply liquid to the cleaning unit during cleaning.
  • a cleaning liquid is applied to the surface to be cleaned via the cleaning unit.
  • an outlet is provided in the cleaning unit, such as a rotating brush head, which is connected to a liquid supply.
  • the liquid supply may for example be a tank with a cleaning liquid.
  • An alternative form of liquid supply is provided in sweeping machines, which generally have a suction mouth connected to a fan which generates in the suction mouth an air flow with which debris and other coarse dirt can be absorbed by the surface to be cleaned, previously have been promoted with the help of possibly driven brooms in front of the suction mouth.
  • liquid is introduced into the air flow.
  • the liquid should preferably not hit the surface to be cleaned, but only moisten the air flow above the suction mouth and, for example, in a dirt collecting container.
  • a valve is provided which is arranged between the liquid supply and the outlet of the liquid supply device and which interrupts the connection between the outlet and the liquid supply when it is closed.
  • the valve must be manually opened and closed by an operator of the floor cleaning machine by operating a switch. If, after cleaning, it is forgotten to close the valve, liquid from the outlet may leak to and contaminate the surface to be cleaned. Conversely, it must also be remembered to open the valve before cleaning operation. Without scrubbing liquid, the scrubber-drier can not achieve a satisfactory result and the sweeper is subject to increased dust generation.
  • a floor cleaning machine with a cleaning unit in which a valve between a liquid supply and an outlet is arranged on the cleaning unit.
  • a pedal on the machine frame of the floor cleaning machine can be configured as an actuating device, so that when the pedal is pressed down, the cleaning unit can be moved to the cleaning position and the valve can be opened somewhat later.
  • the EP 0 162 769 A1 describes a cleaning unit for cleaning a bottom surface, which is connected via a liquid supply device with a liquid supply.
  • the cleaning unit is designed as a suction device with a suction line. By means of two nozzles, the cleaning liquid from the liquid supply device is applied to the floor surface to be cleaned under pressure and sucked through the suction line.

  • the floor cleaning machine may, for example, be a scrubber-drier or a sweeper, driven either by an operator sitting on the machine or is guided as a hand-held machine by an operator behind the machine.
  • the floor cleaning machine has a chassis, with which it can be moved over a surface to be cleaned.
  • the chassis may have both driven and non-driven wheels.
  • the floor cleaning machine comprises a cleaning unit for cleaning the surface to be cleaned.
  • the cleaning unit may be, for example, a suction mouth for sucking debris or coarse dirt from a surface to be cleaned or a brush head.
  • Common to these cleaning units that they are height-adjustable mounted on the chassis. By means of a lifting device they can move between a raised resting position, i. a position in which the cleaning unit is spaced from the surface to be cleaned, and a lowered cleaning position. In the cleaning position, the cleaning unit is regularly at least partially on the surface to be cleaned on or on the surface to be cleaned.
  • a lifting device In order to move the cleaning unit between the rest and the cleaning position, a lifting device is provided.

  • the valve may be a mechanically actuated valve but also an electromagnetically actuated valve.
  • the floor cleaning machine has an actuating device coupled to the lifting device.
  • the actuator opens the valve when the cleaning unit is in the cleaning position and closes the valve when the cleaning unit is moved from the cleaning position to the rest position so that the valve is closed when the cleaning unit is not in the cleaning position.
  • the actuating device can be a sensor which detects the height of the cleaning unit and, when the cleaning unit is lowered into the cleaning position, opens the valve electrically or mechanically. On the other hand, if the sensor detects that the cleaning unit is lifted out of the cleaning position, it can also close the valve electrically or mechanically.
  • the present invention offers the advantage that the liquid supply to the outlet is automatically closed when the cleaning unit is not in the cleaning position.
  • the automatic operating device avoids an additional work step and the floor cleaning machine is more user-friendly.
  • liquid from the liquid supply device is prevented from leaking to the bottom when the floor cleaning machine is not used for cleaning. This prevents in particular that when the floor cleaning machine is turned off, the liquid tank runs empty and no liquid is available when it is to be cleaned.
  • the valve is automatically opened whenever the cleaning unit is in the lowered cleaning position and thus liquid escapes from the outlet when it is needed. It is thus ensured that cleaning liquid is applied to the soil or circulating water is discharged into the suction device.
  • the actuator mechanically couples the lift to the valve.
  • the mechanical coupling of the actuator has the advantage over the electrical coupling that it is more robust. Cleaning units of floor cleaning machines are permanently exposed to dirt and moisture, which can easily lead to malfunction of electrical components.

  • the lifting element is shortened and the cleaning unit is raised so that it comes out of contact with the surface to be cleaned, the part of the weighting force of the cleaning unit previously carried by the surface is transferred to the lifting element via the actuating device.
  • the actuating device is designed such that it closes the valve simultaneously with the lifting, preferably the entire weight force or a part of the weight force of the cleaning unit can be available as a closing force for the valve. There are no additional actuators or motors necessary in this preferred embodiment to close the valve.

  • the lever is pivotable, preferably one parallel to the to be cleaned Surface extending axis, supported on the cleaning unit.
  • the lever is biased by a spring element that pivots the lever such that the valve opens when the lifting element does not lift the cleaning unit. This will ensure that the valve opens when the cleaning unit is in the lowered cleaning position.
  • a manual actuator is provided by means of which the lever can be pivoted to close the valve, e.g. when the cleaning unit is in the lowered cleaning position.
  • the valve can be closed by an operator of a floor cleaning machine, for example, if it is to be parked with the cleaning unit lowered.

Is the cleaning unit 9 in the cleaning position ( FIGS. 4a and 5a ), the lifting cylinder 23 must be shortened to lift the cleaning unit 9. The cleaning unit 9 then pivots against the direction of travel 7 on the struts 19 away from the surface 5 to be cleaned. Conversely, the cleaning unit 9 from the rest position ( FIGS. 4b and 5b ) are lowered by extending the Aushebezylinders 23 on the surface 5 to be cleaned.
