Definitions

  • the invention relates to a mobile floor cleaning machine with integrated fresh and dirty liquid compartments, with a cleaning rotor to be supplied from the fresh liquid compartment and exchanged without tools on a rotor receptacle, and with a suction nozzle conveying into the dirty liquid compartment, with a pair of castors between the cleaning rotor and suction nozzle, and with a handlebar receiving control elements.
  • a cleaning machine of this type already used in practice has on its underside a rotor holder which can be coupled to an accessory, in particular a brush or a drive plate with a pad, by placing the accessory on the floor and moving the device over the accessory and on top of it is put on. All that is required to snap the accessory into place is a brief tap on the motor assigned to the rotor.
  • cleaning liquid mixed with cleaning concentrate is sprayed from the separate fresh water tank onto the floor to be treated via the rotor.
  • the rotor is used to scrub.
  • a beam-like water suction nozzle following the rotor when the machine is pushed forward serves to soak up the dirty water still remaining after scrubbing, so that the floor can be scrubbed thoroughly in one operation and at the same time wiped dry, that is, vacuumed.
  • the known automatic cleaning machine has drives to be connected directly to the mains via a mains cable. In long corridors or large rooms, the power cord must therefore be plugged in frequently. In the case of the machine there are completely separate tanks for fresh and used liquid, so the entire tank volume can be used up to half on average; this also limits the radius of action of the known machine.
  • To operate the cleaning rotor of the known machine a relatively large amount of fresh liquid or industrial water is required, since the bottom surface processed by the rotor is completely unrestricted, so that the liquid can run away on all sides. Relatively much energy is therefore required to suck up the liquid with the aid of the suction nozzle. If you wanted to supply such an automatic cleaning machine from a battery, regardless of the network, the reduction in action would be almost as limited by the high energy consumption as by a power cord.
  • the invention is based on the object of improving the cleaning machine mentioned at the outset in such a way that it can be supplied with electricity from an entrained battery with an increased radius of action compared to cable operation. In particular, it will also do this be favorable to know and / or register the fill level of the fresh and / or dirty liquid compartments at any time and to facilitate the refilling of the fresh liquid compartment with the required detergent concentration.
  • the solution according to the invention is primarily characterized by an adjustable machine frame to be adapted to the diameter of the cleaning rotor with a hanging protective curtain on a peripheral region of the rotor facing away from the suction nozzle.
  • the use of the protective curtain on the side of the cleaning rotor facing away from the suction nozzle ensures that the liquid sprayed or flowing into the area of the rotor essentially remains in the rotor working area of the floor - i.e. where it is used for scrubbing - and that at the same time the
  • the suction power of the water suction nozzle is improved by shielding the rotor side opposite the nozzle except for a generally very narrow gap between the curtain and the floor. In this way, it is possible to create a battery-operated cleaning machine with suction nozzle performance that is significantly reduced compared to the possibilities of a mains drive, which can also process very large areas without constant recharging.
  • the adjustable machine frame assigned to the cleaning rotor is produced from at least two frame parts which are to be pushed apart or into one another approximately radially with respect to the rotor.
  • the frame parts can be connected to each other telescopically, for example.
  • the adjustment itself can be carried out with the help of a motor. In this way, it is possible to largely limit the space enclosed by the machine frame with the protective curtain attached to it to the volume occupied by the cleaning rotor.
  • This adjustment of the volume of the cleaning room is not only advantageous in connection with the power consumption of the suction nozzle, but also makes it possible to reach the edge of the surface to be cleaned with the cleaning agent regardless of the rotor diameter.
  • centering means are to be provided on the adjustable machine frame for centering a cleaning rotor pushed under the device with respect to the rotor holder. Despite the heavy weight of the machine, it is then easily possible to engage or disengage a rotor by raising or lowering the rotor holder of the device and simply pushing the rotor under the device with your foot.
  • a container consisting of a single total space is provided according to another invention, which is divided into a fresh water and a dirty water compartment by an intermediate wall is.
  • a fixed partition wall possibly with the expected final quantitative ratio of fresh water and dirty water corresponding position within the entire space, can be provided, or the partition wall can be designed flexibly as a dense membrane or water bag.
  • the space available overall for the fresh water and dirty water can be gradually converted from a fresh water compartment into a dirty water compartment during operation by moving the partition or partition.
  • This has the further advantage that, after the fresh water has been used up, simply by connecting the fresh water side to a water pipe in order to fill the entire space with fresh water, the dirty water can be automatically expelled from the device (into a drain).
  • the fresh water side and the dirty water side of the container can also be equipped in this case with an inflow or outflow hose or the like.
  • the intermediate wall from filter material or to provide it with filter candles.
  • part of the dirty water always flows back through the filters into the fresh water compartment; This double use also significantly increases the usable water volume.
  • the fresh liquid compartment with a lid that can be swiveled by approximately 90 ° and has an integrated dosing container (for the cleaning concentrate).
  • the dosing container should be designed and preferably equipped with such a scale that the container, when the lid is open, measurably receives the concentrate in the desired amount and empties itself into the fresh water compartment when the lid is closed.
  • FIG. 1 to 3 show a mobile floor cleaning machine in three different views, projections or cuts.
  • the machine consists of a total of 1 car with casters 2 and support rollers 3 and handlebars 4 with control panel.
  • a large part of the interior of the carriage 1 is occupied by a liquid tank designated 5 in total.
  • This has a lid 6 with a metering container 7 attached to it, which has a scale.
  • the scale should correspond to the mixing ratio of fresh water to cleaning concentration.
  • the metering container 7 can be filled according to the predetermined mixing ratio. By closing the lid 6 in the closing direction 8, the contents 9 of the metering container 7 are emptied into the liquid tank 5.
  • the liquid tank 5 consists of a fresh water compartment 10 and a dirty water compartment 11.
  • a plurality of probes 12 are provided in the fresh water compartment 10 for indicating the fill level.
  • the probes can be supplied with an alternating voltage (to prevent galvanic removal of the probes, direct current is not used).
  • the IC switches through as soon as and as long as the probes are covered by a liquid.
  • the fill level can be indicated by LEDs, pointer instruments, warning lights or the like.
  • the fresh water compartment 10 and the dirty water compartment 11 are separated from one another by an intermediate wall 13.
  • the partition can be a fixed partition between the two compartments 10 and 11 as in Fig. 2 or 3 represent. It can also be arranged laterally displaceable or adjustable to separate the compartments 10 and 11 in order to adapt to the respective quantity ratio. 4 and 5, a fixed partition 13 with filter candles 14 inserted therein is shown schematically. 6 and 7, a flexible partition 15 for separating the fresh water compartment 10 from the waste water compartment 11 can be used instead of a fixed partition 13.
  • an adjustable machine frame 16 is attached to the underside of the carriage 1, which consists of at least two approximately radially with respect to that on the underside 17 of the carriage 1 consists in a receptacle 18 coupled cleaning rotor 19 apart or to be pushed frame parts 20, 21.
  • the frame parts 20, 21 are therefore radially displaceable in the direction of the arrows 22 and 23 shown in FIG. 2 in the direction of the receptacle 18.
  • a suction nozzle 25 is shown in FIGS. 1 and 2 see that can have the shape of a squeegee.
  • a curtain 26 is attached to the machine frame 16 according to FIGS. 1 and 4. It is thereby achieved that after the sides shielded by the machine frame 16 or curtain 26, water can practically not run off — at least on a level floor.
  • FIGS. 8 and 9 An embodiment of the rotor changing system is described with reference to FIGS. 8 and 9.
  • a driver star 27 (with a motor 28) provided as a clutch is first raised in the direction of the arrow 29.
  • the rotor 19 is then pushed under the machine until it hits the centering pin 30 shown in FIG. 9 for pre-centering.
  • the motor 28 is lowered in the direction of the arrow 29 such that the driving star 27 enters the driving receptacle 31 of the rotor 19 and engages there.
  • the motor 28 is raised in the direction of arrow 29, switched on briefly, in such a way that the rotor 19 falls off the driving star 27. After the machine has moved away from the side, the rotor 19 can be removed and - if desired - replaced by another accessory.
  • the mobile floor cleaning machine can, according to the exemplary embodiment, either from a battery or directly be operated directly from the network.
  • a battery pack 32 is inserted into the battery compartment (see also FIG. 1) of the machine in a fully wired manner and connected to the machine network.
  • mains operation (220 V, alternating current)
  • the battery compartment 33 is inserted into a power supply unit 34 containing a transformer and a rectifier and is connected to the machine network.
  • the power supply 34 has a connection line 35 to the next socket.
  • the same power supply unit 34 can also be used outside the machine as a charger 36 of a battery pack 32 located in the battery compartment 33 of the machine.
