Definitions

  • the invention relates to a floor cleaning machine, in particular a scrubber-drier, with a housing consisting of a lower part and a hood-like upper part which can be opened in relation thereto, with a plurality of wheels attached to the underside of the lower part, with a brush unit mounted on the lower part by means of a height-adjustable carrier and operated by one arranged on the lower part of the brush drive motor can be driven via a brush gear, with a strip-shaped suction nozzle which is connected to a suction pump, with a tank having two chambers and with several batteries and / or other power supply units.
  • the lower part generally consists of a frame construction welded together from a plurality of steel profiles, which carries a cladding made of sheet metal or plastic on the outside.
  • the brush drive motor, the suction pump, the support for the brush unit, etc. are arranged in the lower part of this frame construction.
  • the brush drive motor which is mounted directly on the brush unit in many other designs. Since at least the brush gear, but in many cases also the brush drive motor, is connected to the brush unit, the brush unit cannot simply be exchanged for another brush unit, for example with a different working width, or for a new one.
  • the one for that Bottom part provided frame construction including cladding is relatively expensive to manufacture and also difficult.
  • the tank is also arranged in the lower part. The batteries are parked on the upper side of the lower part. Cleaning the tank is therefore very difficult and only possible after the batteries have been removed.
  • a relatively low-lying tank has the disadvantage that the tank contents cannot be easily emptied into a spout which is arranged at a distance from the floor. An additional drain pump is therefore usually required.
  • the invention has for its object to provide a floor cleaning machine, in particular scrubber drier, of the type mentioned, which is simpler in construction, in which most components are optimally protected and yet are easily accessible when needed and which is also easy to clean.
  • the lower part is designed as a self-supporting trough which is open at the top and essentially closed at the bottom, the vertical side walls of which extend at least over a third of the total height of the housing and in which at least the brush drive motor, the brush gear, a Lift motor for the carrier, essential parts of the same and the batteries are arranged, and that the upper part contains the tank.
  • the self-supporting tub is of major importance. It replaces the previous frame construction and its cladding.
  • the tub is inexpensive to manufacture, it forms a supporting structure and also a cladding in one.
  • it also provides effective protection against contamination of the most important machine components, since it is essentially closed not only to the side but also at the bottom.
  • the most important machine components are optimally protected inside the tub. This applies not only to the brush motor, the brush gear, the lifting motor and essential parts of the carrier, but also to the batteries and in particular also the electronic control of the machine, which can advantageously be mounted in the tub. After opening the upper part containing the tank, all components contained in the tub are freely and conveniently accessible for service and repair purposes.
  • the new machine Since essential parts of the brush drive, in particular the brush drive motor and the brush gear, are accommodated in the tub in the new machine, the new machine also has the advantage that the motorless brush units can be easily replaced if necessary.
  • the arrangement of the tank in the upper part has the advantage that the tank is relatively high and therefore its contents can be emptied into a spout without a drain pump.
  • the upper part is designed as a self-supporting tank.
  • the upper part can suitably consist of glass fiber reinforced plastic.
  • the design of the upper part as a self-supporting tank simplifies the construction and thus also reduces the production costs and the weight.
  • a further, particularly advantageous embodiment consists in that an operating panel with the essential operating and display elements is arranged on the guide handle, and that the guide handle can optionally be connected to one or the other end of the machine, in particular the tub.
  • the scrubber-drier shown in the drawing has a housing 1, consisting of a lower part 2 and an upper part 3 that can be opened against it.
  • the lower part 2 is designed as a self-supporting, open top and essentially closed bottom tub and is therefore also referred to below as tub 2 designated.
  • the trough 2 and the upper part 3 have an essentially rectangular plan, as can be seen in FIG. 4.
  • the vertical side walls 2a and 2b of the tub should extend over at least one third of the total height of the housing 1, on the one hand in order to be able to accommodate the essential components of the machine in a protected manner and on the other hand to give the tub an appropriate stability so that the The tub also forms a stable lower part without an additional frame construction.
  • the height of the tub 2 depends essentially on the height of the components to be accommodated therein, which will be described in more detail below.
  • the travel drive 4 which drives the main wheels 5, is screwed on and protected from contamination by a hood. Furthermore, the castors 6 are attached to the floor 2c.
  • the tub 2 is suitably made of sheet metal, especially stainless steel.
  • the brush drive motor 7, the brush gear 8 as a support for the brush unit 9 serving support column 10, a lifting motor 11 for the support column, a fresh water pump 12, possibly a recycling pump 13, the batteries 14 and above all the control electronics in a clean and protected environment and easy to maintain.
  • the upper part 3 After opening the upper part 3, as shown in FIGS. 4 and 6, all of the aforementioned parts are easily accessible for maintenance purposes and, if necessary, for repair or replacement. However, if the upper part 3 is folded down, as shown in FIGS. 1-5, then the upper part 3 completely covers the tub 2, which is open at the top, so that the components accommodated in the tub 2 are protected against dirt and also against splash water.
  • the lower edge 3d of the upper part 3 encompasses the upper edge 2d of the tub 2 from the outside, as is shown in FIG.
  • the tub 2 can also be expediently provided with a transverse wall 16 which separates the battery compartment from the rest of the interior of the tub and also serves to stiffen the tub 2.
  • the upper part 3 is expediently designed as a self-supporting tank 17.
  • the tank 17 has a fresh water chamber 17a and a dirty water chamber 17b, which are separated from one another either by a rigid partition wall 18 or by a movable membrane (not shown).
  • the upper part 3 expediently consists of glass fiber reinforced plastic, in particular glass fiber reinforced polyester.
  • the upper part 3 has a large cover at the top, not shown in the drawings.
  • the suction pump (suction turbine) 20 is expediently accommodated in a central cavity 19 of the upper part 3.
  • the cavity 19 is surrounded on all sides by tank sections 17a, 17b, which are completely or partially filled with water.
  • the suction pump 20 is connected via a suction hose 21 to a strip-shaped suction nozzle 22 of a known type.
  • the suction hose 22 and further ventilation hoses 23 serving for cooling purposes of the suction pump 20 are expediently guided along the underside of the tank bottom 17c.
  • the ventilation hoses 23 are only shown in FIG. 3.
  • An exhaust pipe 24 leads downward from the suction pump 20.
  • the upper part 3 When the upper part 3 is closed, it is aligned with the upper end 25a of an exhaust pipe 22 arranged in the tub 2, the lower end of which opens out into the open at the bottom 2c of the tub 2.
  • the connection between the exhaust pipes 24, 25 is automatically sealed when the upper part 3 is closed.
  • a vertically displaceable support column 10 is expediently provided as a carrier for the brush unit 9. As can be seen from FIG. 7, this support column 10 has a square or possibly also rectangular cross section. It stretches through a recess 26 in the bottom 2c of the tub down. However, the greater part of the support column 10 is arranged inside the tub 2, as is its guidance, which can be formed by a plurality of guide rollers 27. The guide rollers 27 are of course mounted in corresponding holders, not shown, which are connected to the bottom 2c of the tub. A seal, not shown, can also be arranged between the recess 26 and the support column 10.
  • the support column 10 With the upper end 10a of the support column 10, an arm 28 is connected, on which the lifting motor 11 engages. With the lifting motor 11, the support column 10 can not only be moved up and down in the vertical direction V, but also the contact pressure of the plate brushes 29 or pad disks on the floor can be regulated by the lifting motor 11.
  • a support plate 30 is connected, which on the one hand carries the brush drive 8 designed as a belt drive and on the other hand also the brush drive motor 7.
  • the latter and the brush gear 8 can thus be raised and lowered together with the entire support column 10.
  • the drive shaft 31 driven by the brush gear 8 is mounted in the interior of the support column 10.
  • one half 32 of a claw coupling or the like is arranged, the other half 33 of which can be plugged together with an output shaft 35 mounted in the brush housing 34.
  • the disk brushes 29 accommodated in the brush housing 34 are driven in a known manner by the output shaft 35 via a distribution gear (not shown).
  • two support straps 36 are fastened to the brush housing 34 on two opposite sides of the support column 10, each of which has a transverse bore 37.
  • two transverse bores 38 are also provided on the opposite sides mentioned, which are aligned with one another in the connected position of support column 10 and brush housing 34, as shown in FIG.
  • the connecting bolts 39 can be inserted into these transverse bores 37, 38 and can be locked by means of the bolts 40 pivotably arranged on the tabs 36.
  • a brush unit 9 is moved downwards by means of the lifting motor 11 until the plate brushes 29 are supported on the floor.
  • the bolts 40 are unlocked and the connecting bolts 39 can then be easily pulled out of the transverse bores 37, 38.
  • the support column 10 can then be moved upwards a bit and the entire brush unit can be pulled out from under the tub 2 to the side or to the front. Another brush unit can then be inserted under the machine. In the opposite way, the support column 10 is then lowered and brought back between the tabs 36 of the new brush unit.
  • the connecting bolts 39 can be inserted into both cross bores 36, 37 and secured by means of the latch 40.
  • the two halves 32, 33 of the claw coupling automatically come into engagement with one another again, as a result of which the drive connection between Drive shaft 31 and output shaft 35 is produced.
  • the brush unit can also be easily removed for cleaning and maintenance purposes and then cleaned, maintained or repaired at a comfortable working height on a work table.
  • the axis A of the connecting bolts 39 serves as a pendulum axis for the brush housing 34 29 better adapt to the floor geometry.
  • a guide handle 41 is also provided, which is expediently designed as an essentially U-shaped bracket.
  • the closed end 41a of this bracket removed from the machine is angled upward.
  • This part 41a which is angled upward, expediently, as can be seen from FIG. 2, encloses an operating console 42 which has the essential operating elements 43 and display elements 44.
  • the bracket 41 is not only ergonomically shaped in this way, but the controls 43 are also easily accessible without having to let go of the bracket part 41a.
  • the control panel 42 is expediently attached to a cross strut 45 of the bracket 41.
  • control panel 42 with all essential operating and Display elements 43, 44 on the bracket 41 is also essential if the scrubber drier is to be converted so that the brush unit 9 should not be arranged at the rear of the machine, as shown in FIGS. 1-6, but at the front, as it is shown in Figure 9. This is described in more detail below.
  • the U-shaped bracket 41 provided as a guide handle has two legs 41b directed towards the machine. These two legs 41b are mounted on the bearing pieces 46 so that they can be pivoted and locked about a horizontal axis B running transversely to the machine longitudinal direction L-L.

  • the bracket 41 By pivoting the bracket 41 about the axis B, the bracket 41 can not only be adjusted in height but also the distance of the bracket part 41a from the narrow side of the machine can be changed. In this way, the bracket 41 can be easily brought into the ergonomically correct working position.
  • one half 48a of a Hirth toothing is fastened to the latter.
  • the other half 48b is attached to one leg 41b.
  • the locking lever 50 provided with a cam 49 normally holds the two halves 48a, 48b of the Hirth tooth system in engagement, as a result of which the bracket 41 is held in the set height position.
  • the locking lever 50 To change this height position, the locking lever 50 is pivoted in the direction C.
  • the spring force of the bracket 41 forces the two halves 48a, 48b apart, so that the bracket 41 then swings up or down leaves.
  • the re-locking takes place in the reverse manner in that the locking lever 50 is moved in the opposite direction of the arrow C.
  • the two bearing pieces 46 advantageously also serve to support the pivot axis of the upper part 3, which in this case coincides with the axis B.
  • a bearing bush 51 is rotatably mounted on the two bearing pieces 46.
  • the two swivel arms 52 are firmly connected on the one hand to this bearing bush 51 and on the other hand to the upper part 3.
  • the upper part 3 can be folded up about the axis B, which is arranged on a narrow side 2a of the tub 2, as shown in FIG. The components contained in the tub 2 are then easily accessible.
