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 with at least one suction nozzle conveying into the dirty liquid compartment, the fresh and dirty liquid compartment having a fixed passage that allows liquid to pass from the dirty into the fresh liquid compartment Partition are separated.
  • Such a mobile floor cleaning machine is known from DE-OS 37 08 087 by the applicant.
  • cleaning liquid mixed with cleaning concentrate is sprayed from the separate fresh liquid compartment 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 suck 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 to a certain extent, ie can be vacuumed off.
  • the known cleaning machine has its own drive with its own energy supply, i.e. with an on-board battery so that it can be operated independently of mains connections.
  • the radius of action of the known automatic cleaning machine is limited by the size of the fresh liquid compartment.
  • the intermediate wall between the fresh and dirty liquid compartment be made of filter material, so that the sucked-back dirty liquid can pass through the intermediate wall into the fresh liquid compartment, whereby the fresh liquid compartment is constantly refilled.
  • this solution is unsatisfactory, since the intermediate wall designed as a filter clogs up very quickly due to the dirt particles, so that not enough dirty liquid gets through the filter into the fresh liquid compartment.
  • EP-A-224 055 discloses an automatic floor cleaning machine which has a fixed partition which has a compensation opening in its lower region.
  • the two compartments of the floor cleaning machine are connected by an overflow pipe, the ends of which are led through the bottom of the respective compartment.
  • EP-A-185 310 discloses a floor cleaning machine whose fixed partition is provided only with a pressure equalization opening in its upper area.
  • the object of the invention is therefore to improve the cleaning machines mentioned at the outset so that they are environmentally compatible Way has a significantly increased radius of action.
  • a mobile floor cleaning machine of the type described in the introduction in that a pressure equalization opening is provided in the upper region of the intermediate wall, and in that an overflow pipe penetrating the intermediate wall is arranged between the fresh and dirty liquid compartment, the inlet opening of which above the floor area in the dirty liquid compartment and whose outlet opening is arranged in the area of the bottom surface of the fresh liquid compartment.
  • the dirty water returned to the dirty liquid compartment initially sediments there, i.e. the solid dirt particles settle on the bottom surface of the dirty liquid compartment, while the dirty water, which is cloudy but not loaded with dirt particles, enters the fresh liquid compartment through the overflow inlet opening arranged at a sufficient height, if the corresponding fill levels both compartments.
  • the liquid flow from the dirt into the fresh liquid compartment depends only on the two fill levels, but not on the pressure prevailing in the container, because of the pressure equalization opening is the same pressure in both compartments. Almost no water is lost during the cleaning process, so that the floor cleaning machine has a very large operating radius.
  • a separating plate separating two regions is arranged in the dirty liquid compartment, the dirty water inlet opening being arranged in one region and the overflow inlet opening being arranged in the other region.
  • the partition plate is arranged approximately diagonally in the dirty liquid compartment and / or if the partition plate has a rough surface. As a result of these measures, the sucked-back dirty water first reaches one area of the dirty liquid compartment, the dirt already sedimenting on the separating plate, in particular due to the rough surface thereof, and there is also no mixing with the already sedimented dirty water in the other area of the dirty liquid compartment.
  • a filter is arranged at the fresh liquid outlet of the fresh liquid compartment. This has the advantage that any dirt particles that have nevertheless entered the fresh liquid compartment cannot escape from it and impair the cleaning process.
  • the filter is designed as a filter cylinder with an exchangeably arranged filter sock.
  • This filter cylinder has openings in the jacket which are covered by the filter sock.
  • the filter is arranged so that it is always below the liquid surface. Due to the movement of the cleaning machine and the associated movement of the water in the fresh liquid compartment, the filter cylinder is flushed again and again by the sloshing movement of the water, so that a blockage is largely avoided.
  • a vacuum monitor is arranged between the filter and the pump connected to the fresh liquid outlet line. Then occurs due If the filter becomes clogged with no or too little liquid through the filter, a corresponding negative pressure is established behind the filter, which is sensed by the negative pressure monitor. This vacuum monitor is then connected to a corresponding display (optically and / or acoustically) so that the operating personnel can change or clean the filter sock accordingly.
  • the mobile floor cleaning machine shown in FIG. 1 has a carriage, generally designated 1, with castors 2 and a handlebar 3 with an operating device (not shown). A large part of the interior of the carriage 1 is occupied by a liquid tank, generally designated 4, which can be closed with a cover 5.
  • the liquid tank 4 consists of a fresh water compartment 6 and a dirty water compartment 7, the two compartments being separated from one another by a fixed partition 8.
  • a cleaning rotor 9 On the underside of the carriage 1, a cleaning rotor 9 is shown, which can be driven by an invisible drive.
  • a plurality of suction nozzles 10 are provided, which are arranged on a suction bar 11.
  • a suction hose 12 with a connector 13 is connected to the suction bar 11 and opens into the dirty liquid compartment 7 of the liquid tank 4.
  • a pressure equalization opening 14 is provided in the intermediate wall 8 between the fresh and dirty liquid compartment 6, 7 in the upper region of the tank 4 (FIG. 2), which, when the naturally aspirated engine is not shown, is switched on Suction of the dirty water through the suction nozzles 10 ensures a uniform vacuum in the liquid tank 4.
  • the dirty liquid compartment 7 is divided into two areas by a diagonally arranged partition plate 15.
  • the partition plate 15 is only hinted at the other parts still recognizable in the tank.
  • the dirty water inlet opening (socket 13) is arranged in the upper area 16 of the wetting liquid compartment 7, so that the dirty water first enters the upper area 16. 2, a float 17 and a filter screen 18 are also shown in the upper region 16 of the dirty liquid compartment 7.
  • an intermediate wall 8 penetrating overflow pipe 19 which extends substantially parallel to the intermediate wall 8 and comprises two 90 o angled orifice nozzle, an inlet opening 20 and an outlet opening 21.
  • the inlet opening 20 is in the soiled liquid compartment 7 arranged above the bottom surface of the same, but below the diagonal separating plate 15 in the lower region 22 of the dirty liquid compartment 7.
  • the outlet opening 21, on the other hand, is arranged in the region of the bottom surface of the fresh liquid compartment 6.
  • a floating suction funnel 24 is arranged in the fresh liquid compartment 6 in the fresh liquid compartment 6 .
  • This suction funnel 24 is provided with a filter which is designed as a filter cylinder 25.
  • This filter cylinder 25 has a closed cover and bottom, but in the latter there is an outlet spout 26.
  • the jacket 27 of the filter cylinder 25 is heavily perforated, which is not shown in the drawing.
  • a filtering stocking 28 is drawn over the cylinder 25 and is preferably made of synthetic fabric with a corresponding mesh size (30 to 1000 ⁇ m).
  • a vacuum monitor 30 is connected via a T-piece, which is also only in principle in FIG. 3 is shown.
  • the liquid tank 4 When the automatic cleaning machine is started up, the liquid tank 4 is completely filled, ie both liquid compartments 6, 7. In the example, the tank 4 has a volume of approximately 60 l. If the naturally aspirated engine (not shown) is put into operation, a uniform negative pressure builds up in both liquid compartments 6, 7 due to the pressure compensation opening 14. The dirty water returned through the suction nozzles 10 passes through the suction hose 12 and the nozzle 13 or dirty water inlet into the upper region 16 of the dirty liquid compartment 7. The dirty liquor is now initially in the upper region 16 and does not yet come into contact with the one below the separating plate 15 liquid, so that there is no mixing with this partially clarified solution. The one in Solid dirt contained in dirty water can settle on the surface of the separating plate 15, which is preferably ribbed.
  • the liquor must pass through in order to reach the other area 22 of the dirty liquid compartment 7.
  • a sedimentation process takes place, i.e. the solid dirt particles settle on the bottom of the liquid compartment 7.
  • the partially clarified liquid which is no longer loaded with solids, passes through the inlet opening 20 of the overflow pipe 19, which is located approximately at the 40 l mark. This liquid enters the fresh water compartment 6 through the overflow pipe in the bottom area thereof, so that the pre-clarified liquor from the dirty water compartment 7 is directed opposite to the filter cylinder 25 to the bottom of the fresh water compartment 6.
  • the pre-clarified liquor which has entered the fresh liquid compartment 6 is discharged by the drain pump 29 via the filter cylinder 25 sucked in and pumped via the cleaning rotor 9 onto the cleaning surface.
  • the filter cylinder 25 is arranged so that it is constantly washed around in the liquid compartment 6. Due to the slight sloshing movements while driving, the filtering stocking 28 is flushed out again and again so that it does not clog up so quickly.
