Definitions

  • the invention relates to a mobile wet cleaning machine with a first tank for cleaning liquid, which is directed from this tank into the effective range of at least one drivable cleaning tool for the floor surface to be cleaned, and with a second tank, which is provided with a filter device, into which one of the Suction foot of cleaning liquid absorbed from the bottom surface is introduced via a suction pipe and can be brought out of the cleaning liquid into the first tank.
  • the liquid consisting of dirty water is sucked from the bottom into the second tank, which consists of two subunits.
  • the one subunit that receives the dirty water there is a filter through which the water reaches the second subunit, from which it is sucked into the first tank by means of a pump.
  • the inlet opening to the pump line is closed by an additional filter.
  • This known wet cleaning machine which is of relatively large design, allows the cleaning liquid to be used again and thus a relatively long operating time before all of the cleaning liquid has been used up and therefore refilling is necessary.
  • it is relatively complicated and complex, particularly since it requires a pump for the transport of liquid from the second tank into the first tank, for which additional drive energy is required.
  • This known wet cleaning machine has a compact design and can also be designed as a small unit.
  • it has the disadvantage that the volume of the amount of cleaning liquid to be used during a cycle is limited by the volume of the pure water bag, since the dirty water drawn off from the floor cannot be reused.
  • a wet cleaning machine of the type mentioned at the outset is designed according to the invention in such a way that the two tanks are communicatively connected to one another.
  • a particularly compact design of the wet cleaning machine according to the invention is obtained when the two tanks are separated from one another by a common wall.
  • the communicating connection of the two tanks can take place by means of a pipeline, which can preferably be shut off in order to be able to interrupt the connection between the two tanks if it is not intended to use the absorbed cleaning liquid again.
  • the lower wall of the common wall can there may be an opening forming an outlet opening for the second tank, which opening may be closable.
  • the two tanks are connected through the opening in the common wall.
  • the wall common to both tanks can also be in the form of a fine filter, so that absorbed cleaning liquid can pass through this fine filter from the second tank into the first tank, while dirt particles are retained by the fine filter.
  • the wall common to the two tanks can also be removable in order to obtain a particularly large liquid container in this way.
  • connection between the second tank and the first tank takes place via an outlet opening, this can be covered by a fine filter.
  • the second tank in the first tank, so that the maximum dimensions of the liquid receiving space are given by the first tank, the cleaning liquid taken up from the second tank entering the first tank, for example in that at least the bottom wall of the second Tanks contains a fine filter or consists of a fine filter.
  • a closable outlet connection can be provided in the bottom of the first tank, and in the first tank, in the absence of the second tank, a third tank which holds the cleaning liquid can be inserted, the bottom opening of which can be connected to the outlet connection. In such a case, the outlet end of the suction pipe is then directed into the first tank.
  • the filter device can have a filter basket suspended at the top in the second tank, to which the outlet end of the suction pipe is aligned.
  • the wet cleaning machine shown in FIG. 1 is a machine to be guided by the user on the operating handle 10, which runs on wheels 2, 3 and has a plate-shaped cleaning brush 7 which is driven in the direction of the arrow during operation.
  • the wet cleaning machine is advanced in a known manner by slightly inclining the cleaning brush 7, so that the portion of the cleaning brush 7 which is in engagement with the floor exerts a propulsive effect.
  • the cleaning brush 7 is fed via a hose 6 from a first tank 4 housed in the housing 1 of the cleaning machine, which supports the cleaning process and which is sucked up behind the housing 1 of the cleaning machine in a known manner by the suction base 8 and via a hose 9 into a second Tank 5 is performed.
  • the user pivots the handle 10 'in the direction of the operating handle 10, as a result of which the motor (not shown in FIG. 1) rotates the cleaning brush 7.
  • the water supply and suction process is carried out in a known manner.
  • the operation of the wet cleaning machine is interrupted.
  • the wet cleaning machine shown in FIG. 2 has the same basic structure as the wet cleaning machine from FIG. 1, and the same parts are identified by the same reference numerals.
  • the cleaning brush 7 is driven by an electric motor 21, which is usually fed by a battery, not shown.
  • hose 6, which can also be in the form of a rigid pipeline there is a valve 22 which, when the wet cleaning machine is at rest, prevents cleaning liquid from flowing out of the first tank 14.
  • This tank 14 corresponds essentially to the tank 4 from FIG. 1, while the tank 15 arranged next to the tank 14 corresponds to the tank 5 from FIG. It can be seen that the tanks 14 and 15 are separated from one another by a common wall 17 and are closed by means of a cover 16 hinged to the housing 1.
  • a pump 19 housed in the housing 1 generates a negative pressure in the space above the tank 15 via a pipeline 20, with the aid of which the used cleaning liquid, usually water, is sucked up from the suction base 8 and conveyed into the tank 15 via the hose 9 .
  • the two tanks 14 and 15 are connected by a pipe 23, the ends of which are led through the bottom of the respective tank.
  • a slide 24 to be actuated by hand.
  • the end of the pipeline opening into the tank 15 is covered by a cup-shaped fine filter 25, which can consist of metal or plastic mesh.
  • a peg-shaped coarse filter 18 is suspended in the tank 15, which can have the shape of a metal or plastic sieve and into which the outlet end of the hose 9 opens.
  • the tanks 14 and 15 are communicatively connected to one another.
  • cleaning liquid flows from the tank 14 through the pipeline 6 to the cleaning brush 7 driven by the motor 21, and the wet cleaning machine is moved over the floor in the manner explained in connection with FIG.
  • the cleaning liquid remaining on the floor is sucked up by the suction foot 8 and conveyed via the hose 9 into the tank 15, larger dirt particles being retained in the coarse filter 18.
  • cleaning liquid passes from the tank 15 via the pipeline 23 into the tank 14 and is returned to the cleaning brush 7.
  • the fine filter 25 retains dirt particles that have passed through the coarse filter 18 in the tank 15, so that there is always practically completely cleaned cleaning liquid in the tank 14.
  • the slide 24 is closed.
  • the cleaning liquid from the tank 14 is then used for the cleaning process and used cleaning liquid is taken up from the bottom by the suction base 8 and conveyed into the tank 15 via the hose 9. If the cleaning liquid in the tank 14 has been used up, liquid must be topped up, in which case the used cleaning liquid can also be removed from the tank 15.
  • the wet cleaning machine according to FIG. 3 differs from the wet cleaning machine according to FIG. 2 essentially only in that the communicating connection of the tanks 14 'and 15' is not formed by a pipe, but by an opening 23 'in the common partition 17'.
  • the opening 23 ' is covered on the side facing the tank 15' with a fine filter 25 ', for example made of metal or plastic mesh, and can be closed by means of a schematically indicated slide element 24'.
  • this slide element is raised somewhat from the position according to FIG. 3 and is clamped in front of the opening 23 '.
  • the coarse filter 18 ' has essentially the shape of a flat frame which is suspended in the upper part of the tank 15', so that the water from the hose 9 'is directed onto this filter from above.
  • the intermediate wall 17 'can also consist of a fine filter held in a frame and / or can be inserted removably. The latter also applies to the partition 17 from FIG. 2.
  • the wet cleaning machine shown in FIG. 4 is constructed somewhat differently from the wet cleaning machines according to FIGS. 2 and 3. Identical or corresponding parts are designated by reference numerals increased by 100 compared to the reference symbols from FIG. 2.
  • the wet cleaning machine has a housing 101, wheels 102, 103, a plate-shaped cleaning brush 107, which is supplied with cleaning fluid via a pipeline 106, and a suction foot 108, from which the absorbed cleaning fluid via the hose or the pipeline 109 is passed into the tank 115.
  • a vacuum is generated in the usual way by means of the pump 119 via the line 120 in the space created by the tank 114 and the cover 116 attached.
  • the motor for driving the machine is not shown, but there is a schematically indicated battery 100 in the front part of the machine, which supplies the electrical energy for the operation of the drive motor and the pump 119, not shown.
  • the tank 115 is suspended in the significantly larger tank 114.
  • the hose or the pipe 109 opens into the tank 115, so that the cleaning liquid absorbed by the suction foot 108 is conveyed into the tank 115.
  • a coarse filter can be provided in the upper part of the tank 115 in the manner indicated in FIG. 2 or FIG. 3.
  • the entire tank 115 as shown schematically, consists of a fine filter, for example of metal or plastic mesh.
  • the tank 114 serves to hold the cleaning liquid, which can reach the pipeline 105 and thus the cleaning brush 107 via a closable, schematically indicated outlet connection 130.
  • cleaning liquid consumed during operation is absorbed by the suction foot 108 and conveyed into the tank 115 via the pipeline 109, this cleaning liquid can pass directly into the tank 114, while dirt particles are retained by the possibly present, not shown coarse filter or by the wall of the tank 115 forming a fine filter.
  • the wet cleaning machine according to FIG. 4 can also be used in a conventional manner, as shown in FIG. 5.
  • the suspended tank 115 ′ serves as a container for the cleaning liquid, and its bottom is connected directly to the outlet connection 130 via a pipe connection.
  • the cleaning liquid absorbed by the squeegee 108 is pumped from the squeegee 108 via the hose or the pipe 109 into the tank 114, for which purpose the outlet end of the hose or the pipe 109 has of course been pivoted accordingly in relation to the position from FIG.
