Definitions

  • the present invention relates to a floor cleaning machine.
  • a machine suitable for wet cleaning comprising suction means for drawing up cleaning liquid applied to the floor surface.
  • Cleaning apparatuses are known which are also capable of cleaning closely along a wall of a space, using a rotating brush and cleaning liquid. Manual cleaning work is hereby avoided as far as possible.
  • suction means usually in the form of so-called squeegees, for drawing up the cleaning liquid applied to the ground extend on at least one side of the apparatus further to the outside than a rotating brush.
  • suction means are arranged both in front of and behind a brush so that such a small apparatus can be used in both forward and rearward direction.
  • Both respective suction means must extend further outward than a rotating brush for collecting all cleaning liquid used for cleaning a floor surface.
  • brushing of a floor surface along a wall is a problem with these known cleaning apparatuses which can be used in two directions.
  • GB-A-486,499 relates to a floor treating machine, comprising a frame, a rotatable brush, drive means for driving the brush and a suction nozzle for removing used cleaning liquid from the treated surface, whereby the suction nozzle is movably mounted so that its position is variable angularly in a horizontal direction in relation to the brush.
  • WO-A-92/13480 discloses a floor treating machine with at least two floor treating bodies of which at least one is suspended so as to be alterable in position such that the working width of the machine can be changed.
  • US-A-4,817,233 refers to a floor scrubbing machine having a scrub brush, a suction squeegee behind the scrub brush and another one in front of the brush.
  • US-A-4,173,056 discloses a floor scrubbing machine having 2 brushes and a vacuum squeegee water pick-up system, the position of which is controlled by a steering arm. The vacuum squeegee is also connected to the frame by another arm which is not disposed parallel to the steering arm.
  • the object of the present invention is to provide a compact apparatus which is easily manoeuvrable and can operate in two directions.
  • the present invention provides an apparatus for cleaning a ground, comprising:
  • the suction means present in the apparatus of the invention preferably comprise a first suction member in front of the brushing means and a second suction member behind the brushing means. These suction members are preferably likewise arranged on a common housing.
  • the housing can be easily urged, for instance counter to spring action, out of a slightly sideways position into a position in which the housing and the suction members arranged thereon hardly protrude relative to the brushing means. As a result, the floor surface can be brushed clean precisely along an edge.
  • An manually-operated floor scrubbing apparatus (figure 1) comprises a frame or chassis (2) to which tanks (3) and (4) respectively are arranged, for instance provided respectively with drawn up liquid and with cleaning liquid for applying to the ground surface (G).
  • Push bars (43), (44) extend from chassis (2) to a position close to a transverse hand-grip, which extends transversely of the bars and in which are arranged switches (5a), (5b), (9a), (9b), and (9c) for actuating the different functions of apparatus (1), such as ON/OFF-suction, brushing etc.
  • the tank (4) is connected to a housing (5) in which is situated a brush (6) which can be driven rotatably on a horizontal axis using a drive motor (7) and transmission means (8).
  • the brushing operation is preferably performed by brush (6) while fresh cleaning liquid from tank (3) is supplied thereto.
  • squeegees (10) and (11) extend substantially parallel to brush (6) and are connected to the other tank for drawing up the applied cleaning liquid.
  • Apparatus (1) can be used in forward direction, wherein squeegee (11) provides the suction, as well as in rearward direction, wherein squeegee (10) provides the suction.
  • the brush (6) is fixedly connected to chassis or frame (2).
  • the housing is connected to the chassis by means of two support arms (12) and (13) which extend substantially parallel and which are preferably provided on both ends with ball joints.
  • a stabilizer rod (14) is arranged on the upper side of housing (5), which rod is preferably connected with a ball joint (15) to the chassis or frame.
  • the apparatus (1) Adjacently of the rear wheels, of which rear wheel (20) is shown in figure 1, the apparatus (1) is provided with a running wheel (21), which provides further support when the size of brush (6) is minimal, for instance due to wear thereof.
  • the position of running wheel (21) can be adjusted using an adjusting mechanism (22).
  • the apparatus (1) when it approaches a wall W, can be pressed thereagainst with contact wheels (30) and (31), whereby the housing (5) is urged sideways out of the rest position, which in the shown embodiment is situated slightly to the right-hand side of brush (6) and rear wheel (20).
  • the brush (6) can thus rotate directly along the wall W and there provide the required cleaning action.
  • the sideways movement is brought about counter to the action of a coil spring (33), so that on leaving the cleaned area along the wall W the housing (5) with squeegees (10) and (11) is urged back to the position on the right-hand side as in figure 2A, wherein in order to properly draw up the liquid the squeegees (10) and (11) extend slightly further outward on the right-hand side of brush (6) than in the position shown in figure 2B.
  • the transverse distance of the housing (5) between the positions shown in figures 2A and 2B preferably amounts to about 20-50 mm, more preferably about 32 mm, this being sufficient to clean the edges along a wall adequately.
  • housing (5) with squeegees (10) and (11) is possible in both the forward and rearward direction of travel of apparatus (1), whereby the edges along all walls of a space can be cleaned with the shown preferred embodiment.
