  • the invention has as its object to provide a floor cleaning device that can achieve an advantageous and in particular hygienic handling with the simplest possible structure.
  • a floor cleaning device of the type in question in addition to cleaning robots and attachments for conventional household vacuum cleaner includes.
  • the closure means automatically act in response to an operating condition of the device in action.
  • a floor cleaning device which has a shutter mechanism for recording which, in the cleaning operation, opens the way to the receptacle, but closes tightly during standstill or during transport, if appropriate in addition to a discharge opening. This ensures that once recorded dirt does not come into contact with the ambient air and can not fall out of the device.
  • the opening and closing of the recording corresponds to the operating conditions.
  • closure means there is a usual operating state in which the closure means are held in an open position from the fact that the floor cleaning appliance stands with the brush running on the floor to be cleaned or is moved over it.
  • the closure means can be actuated automatically depending on an operating state of the device, so actively on locking mechanisms in the closed position or be shifted out of this into the open position.
  • an actuation takes place by lifting the device.
  • this embodiment of the invention is a leakage of collected in the receptacle dirt, for example, counteracted during transport of the floor cleaning device. It is also conceivable that an extendable in the course of lifting suspension causes a lever-operated closing the opening.
  • a counter-torque of an electric drive motor can be used for actuating the closure means, wherein preferably the counter-torque of the drive motor of the brush and / or of the travel movement serving is used.
  • This can also be combined in response to a lifting of the device, this lift is recognized by known abyss sensors, after which the drive motor stops, consequently the counter torque is eliminated and a coupled to the engine mechanism displaces the closure means in the closed position.
  • the general stopping of the drive motor for the brush and / or for the driving movement leads to the same reaction by closing the preferably spring-biased or by Gravity moved shutter.
  • a separate actuating means acting on the closure means wherein more preferably the separate actuating means is an electric motor or a differently formed actuator.
  • the receptacle is mounted vertically movable in the device and due to its own weight when lifting the device displaced vertically downwards, wherein in the course of this displacement, the opening moves relative to a closure means in the closed position.
  • the closure means is preferably a device housing-side wall or the like, which closes the receptacle against the opening when the device is lifted.
  • the receptacle is associated with a separate fan, wherein a trajectory of the fan blades coincides with the opening and a fan blade at a standstill closes the opening.
  • a floor cleaning device 1 in the form of a cleaning robot with a chassis 2, which the underside, the floor to be cared 10, driven by electric motor Verfahrer 3 and beyond the lower edge of the chassis bottom 4 protruding, also driven by electric motor brush 5 carries.
  • the chassis 2 is covered by a device hood 6, wherein the floor cleaning device 1 has a circular plan.
  • the Verfahrer 3 are downstream of the brush 5 in the usual direction of travel r of the floor cleaning device 1, wherein further the brush 5 downstream a keying plate-like dirt ramp 7 is provided, via which the brushed dirt is dropped into a container-like receptacle 8.
  • the slip is in this case determined by a comparison between the traveled distance of the floor cleaning appliance 1 and the revolutions of the driven wheel 3 driven via the electric motor 11 and / or the brush 5 driven by the electric motor 12.
  • the rotation determination can preferably take place directly on the traversing wheel 3 or on the brush 5 or alternatively on the traversing wheel 3 and on the brush 5 ,
  • the ground detection can also be carried out by determining the driving resistance, including at a slip-free translation, for example via a toothed belt between the drive motor and driven means, the current consumption of the electric motor 11 of the Verfahrrads 3 and / or the current consumption of the motor 12 of Brush 5 is detected.
  • the front wheel 9 is arranged to detect the distance traveled and has a sensor 13, the values of which are detected by a processor 14 integrated in the floor cleaning device 1.
  • the determined rotational speeds of the traversing wheel 3 and / or the brush 5 as well as alternatively or also collectively the values of the power consumption of the traversing electric motor 11 and / or the brush electric motor 12 are transmitted to the latter.
  • an electronic memory 15 is furthermore provided, in which comparison values for slip and / or driving resistance of various floor coverings are stored.
  • the processor compares the measured values such as slip and / or travel resistance of the travel wheel 3 or the travel wheel electric motor 11 and / or the brush 5 and the brush electric motor 12 with the values stored in the memory 15 and derives a signal therefrom for controlling the floor cleaning device 1 from.
  • the distance traveled is taken up by the follower wheel 9, which measured distance is set in relation to the elapsed time since the last measurement. From this, a clear statement about the speed of the floor cleaning device 1 can be achieved. Since the running resistance and the slippage relative to the floor 10 on carpet is greater than on hard floor, the speed of the floor cleaning appliance 1 is lower on carpet. In addition, due to the greater resistance, the current of the electric motor 11 of the traversing wheel 3 increases. This also applies to the brush 5 of the floor cleaning device 1, the mechanical resistance increases to carpets, which has an increase in power consumption. Likewise, the rotational speed of the brush 5 also decreases.
  • the values detected by the processor 14 are compared with the stored reference values for a reference bottom.
  • the signal derived therefrom can serve, for example, for the navigation of the floor cleaning appliance 1, in particular for floor cleaning appliances 1, in particular cleaning robots, which should not drive on certain floor coverings.
  • the drive power of the brush 5 and the Verfahrmann 3 can be adjusted according to the determined flooring.
  • a signal for adjusting the brush 5, in particular the board position of the brush 5 can be derived via the chassis bottom 4, so that, for example, for gentler brushing of carpets, the brush 5 is raised via a known rocker arrangement.
  • the in the 4 and 5 in an embodiment schematically illustrated receptacle 8 is closed in response to an operating condition of the floor cleaning device 1. It is thus provided that the receptacle 8 is closed when the floor cleaning appliance 1 is raised from the floor 10 to be maintained and / or when the floor cleaning appliance 1 is switched off, in particular switching off the electric motors 11 and / or 12 of the traveling wheels 3 and / or the brush 5 , so that even in the recording 8 collected dust or dirt can not escape from this uncontrolled again.
  • the receptacle 8 can have an activatable closure means 16 in the form of a closure flap 17, which in any case closes an entry opening 18 of the receptacle 8 due to the operating state.
  • closure flap 17 is articulated on the upper side of an entry opening 18.
  • the free end of the closure flap 17 is connected via a side of the receptacle 8 extending lever 19 with an axis of a Verfahrrades 3, which is part of an extendable chassis 20, in connection.
  • the chassis 2 of the floor cleaning appliance 1 which is not shown here, is supported on the chassis 19, for example in the region of an axis 21, by means of a shell-like support surface 20, for example.
  • the latter is loaded by a tension spring 22 in the direction of the support shell 20.
  • the already mentioned dirt ramp 7 is articulated in the lower edge of the entry port 18, d. H. articulated in the region opposite the articulation region of the closure flap 17.
  • FIG. 5 A like in Fig. 5 schematically illustrated lifting the floor cleaning device 1 leads to a rebound of the chassis 19, via which latter and via the lever 23, the displacement of the shutter 17 is effected in the entry opening-closing position.
  • a further alternative embodiment for the automatic closing of the receptacle-entry opening 18 show the 6 and 7 ,
  • the receptacle is floating in the floor cleaning device 1 and stored in the chassis 2, so that the floor cleaning device 1 to the receptacle 8 in the vertical direction is relatively movable.
  • the chassis 2 In the usual operating position (shown Fig. 6 ), the chassis 2 is supported on the receptacle 8, to which further the chassis 2 has a pocket-like cavity 25 for the receptacle 8.
  • the receptacle 8 In the process of the floor cleaning device 8 is hereby the receptacle 8 for collecting the swept up or sucked Dirt entrained, which recording 8 slides on skid-like spacers 33 on the floor 10.
  • handling technology advantageous is an embodiment in which the relative vertical displaceability of the floor cleaning device 1 and the chassis 2 relative to the receptacle 8 is stop-limited, so that a further lifting of the in Fig. 7 shown position the entrainment of the receptacle 8 causes.
  • the closure of the receiving port 18 may be coupled to the operating state of the brush 5 driven via the electric motor 12 and / or the traction wheels driven by the electric motor 11.
  • a mechanical closing of the entry opening 18 can be achieved via a sensor system for detection of the abyss during lifting of the floor cleaning appliance 1.
  • the 8 and 9 show an embodiment of this.
  • the closure means 16 is formed as a hinged in the upper edge region of the entry port 18 closure flap 17.
  • this flap 17 is coupled to the engine - in the illustrations of the electric motor 12 for the brush 5 - via a toggle mechanism 27, wherein in the region of the knee joint 28 a chassis negligence fixed tension spring 29 biases the mechanism 27 in a closed position of the flap 17.
  • the Fig. 8 shows the operating situation with the electric motor 12 for the brush 5, in which situation by the engine counter torque of the toggle mechanism 27 against the spring force of the tension spring 29 is acted upon so that the shutter 17 is held in the open position via this mechanism.
  • the counter-torque decreases, so that the toggle mechanism 27 due to the spring force of the spring 29 back into his Fig. 9 is spent in the basic position shown, which causes about the mechanism pivoting the shutter 17 in the entry port closure position.
