Definitions

  • the invention relates to a floor cleaning device with a floor nozzle head having a spray nozzle and adjoining it a suction nozzle, wherein a cleaning liquid is to be applied from the spray nozzle in an area with approximately the working width of the suction opening of the suction nozzle and is to be taken up again with the suction nozzle.
  • a cleaning liquid is sprayed onto the floor via a spray nozzle directly in front of the suction nozzle (when pushing the device).
  • the floor nozzle head which is connected to a hand pipe, pressure hose and suction hose, is pulled or pushed in straight lines with constant suction over the surface to be cleaned.
  • the cleaning liquid that gets onto the floor dissolves the dirt and is drawn off together with the dirt via the suction nozzle and a hand tube suction hose into a dirty liquor container.
  • the action of the cleaning liquor is usually short by simply moving the surface to be cleaned, but the time can be increased by spraying and then vacuuming off separately.
  • Stubborn soiling in textile coverings can often not be achieved simply by spraying and vacuuming the cleaning liquid but can only be removed by mechanical support.
  • Corresponding scouring or rubbing devices are not attached to the floor nozzle head because this head should slide easily to make work easier.
  • the sliding surfaces of conventional floor nozzle heads are therefore usually made of solid, smooth, sliding material, such as. B. metal or plastic. Since it is difficult to produce the friction required to increase the cleaning effect with this relatively smooth floor nozzle head, so-called attachments or auxiliary devices with electromotive brush rollers are used in practice. Due to their design, these pre- and additional devices usually weigh several kilograms, so they are - at least from an application technology point of view - difficult to describe. They are unwieldy, have little access to the edges and are actually only suitable for large, uncovered areas. In addition, the purchase cost is relatively high.
  • the invention has for its object to design a conventional, simple floor nozzle head without complex preliminary or additional devices so that it retains the smoothness required for facilitating the work and still offers the possibility of merely moving back and forth, that is to say by advancing and Withdrawal to provide the mechanical floor treatment required to enhance the cleaning effect.
  • the solution according to the invention is characterized for a floor cleaning device of the type mentioned at the outset with a floor nozzle head having a spray nozzle and immediately adjacent to it with a suction opening, by a bristle strip which is pivotable about an axis running parallel to the suction opening and is mounted directly on the suction opening and extends over the entire width of the floor nozzle head a stop limiting the swivel angle of the bristle strip when pulling the floor nozzle head.
  • a brush or bristle strip is thus movably attached to the floor nozzle head in such a way that it tilts backwards under the experience of the large forces required for pushing the device and does not significantly increase the normal sliding resistance of the floor nozzle head.
  • the bristle strip according to the invention should stand up and be held in a position effective for the additional mechanical treatment by a stop. Since the required forces for pulling a suction nozzle can be better compensated ergonomically than the forces for pushing the nozzle and due to the bristle strip according to the invention, significant additional forces only occur when pulling, both the resistances established during pushing and pulling due to the brush mechanism can be significantly reduced the physical strain on the workforce going beyond the previous level can be overcome.
  • the bristle strip is assigned a stop restricting its swiveling movement even when the floor nozzle head is pushed.
  • This attachment should be such that the bristle strip in the inactive position only tilts so far away that it automatically tilts back into the position effectively set up for mechanical cleaning during the transition to pulling.
  • the bristle strip is thus held in an inactive position when pushed so that when the direction changes, that is, during the transition from pushing to pulling the floor nozzle head, it swings automatically into the active brush cleaning position. Accordingly, while the tips of the bristles of the bristle strip in the inactive position, i.e.
  • the bristle strip preferably has a mounting rail which is pivotally mounted at its longitudinal ends in side walls of the floor nozzle head. To attach the bristle strip, it is then only necessary to make bearing holes in the side walls which are approximately at right angles to the longitudinal axis of the mounting rail.
  • a rail made of metal or plastic with a U-shaped cross-section with bristles made of natural fiber or plastic attached to the U-legs in a force-fitting or material-locking manner is advantageously provided as the mounting rail.
  • Such a U-shaped mounting rail ensures sufficient stability for the operation of the floor cleaning device, despite the low manufacturing effort.
  • the assembly of the bristle strip as a whole is facilitated if the mounting rail in the side walls is assigned receiving holes with a clear width exceeding the largest rail diameter. Under these circumstances, if the bristles fold over when they pass through the holes and then straighten up again, the bristle strip can simply be pushed through the receiving holes for locking.
  • the pivoting movement of the bristle strip becomes particularly smooth and, in addition, an undesired slipping out of the bristle strip from its storage is avoided if the bristle strip has a bristle gap in the longitudinal sections provided for storage in the receiving holes. If small tufts of bristles then protrude from the longitudinal ends of the bristle strip penetrating through the side walls, an unwanted slipping out of the bristle strip is practically excluded.
  • the bristle strip could also be secured by threads and screws or the like. Simple plugging in and automatic securing, for example through the bristle gaps, are much more practical.
  • the active and inactive swivel position of the bristle strip Limiting stops are created according to a further invention without any significant additional effort if the receiving holes of the side walls are shaped as segment recesses approximately in the manner of a quarter-circle cutout opening into a smaller full circle and if the circular cutout radii of the segment recesses are designed as stops for limiting the pivoting movement of the bristle strip and For the storage of the back of the mounting rail with a possibly U-shaped cross-section, a smaller full circle is expediently provided at the top of the quarter-circle cut-out.
  • the receiving hole then has approximately the shape of a conventional keyhole with an excessively spread beard slot.
  • the floor nozzle head 1 and 2 has a floor nozzle head, not designated as a whole, with a spray nozzle 2 and this associated spray chamber 3 with an umbrella-shaped cover 4 and side walls 5.
  • the floor nozzle head 1 also includes a suction nozzle 6 with a nozzle which reduces the sliding resistance of the device Suction opening 8 with slide rail 7.
  • the spray nozzle 2 is supplied with cleaning fluid via a hose 9 with a pump connected to it.
  • the cleaning liquid is sprayed from the spray nozzle 2 - approximately in the working width of the suction opening 8 - onto the floor to be cleaned.
  • previously applied cleaning liquid is drawn off together with already loosened dirt via the suction nozzle 6 in the direction of the arrow 10 into a dirty liquor container.
  • the mounting rail 12 of a brush or bristle strip is pivotally fastened in mounting holes 11 of the side walls 5 serving as a bearing, such that it is inactive as shown in FIG. 2 when the floor nozzle head 1 is pushed in the direction of the arrow 14 (FIG. 2) Position 15 folds away (almost) without a floor, but when pulled in the direction of arrow 16 folds into an active position 17 against an impact, for example against a wall of the suction opening 8. Even in the inactive position 15, a stop 18 can be provided for the bristle strip 13, which ensures that the Bristle strip 13 is not kept completely but almost free of soil and is therefore automatically folded into the active position 17 when the movement is reversed - from pushing to pulling.
  • gaps 20 are shown in the region of the receiving holes 11 of the bristle strip 13 within its bristles 19 and 5 additional tufts of bristles 21 outside the side walls.
  • the gaps 20 and the tufts of bristles 21 ensure simple assembly of the bristle strip 13 and, at the same time, secure storage in the receiving holes 11.
  • the receiving holes 11 according to FIG. 3 are designed as segment recesses approximately in the form of a quarter-circle section which preferably merges into a smaller full circle.
  • the radii of the segment cutout, designated as a whole by 22 can at the same time be designed as a bellows 23 for fixing the bristle strip 13 when pulling the floor nozzle head 1 in the direction of arrow 16 and as a stop 24 when pushing in the direction of arrow 14.
  • the U-shaped mounting rail 12 is in the segment cutouts 22 of the receiving holes 11 when pivoting back and forth essentially at three points, namely at the tips 25 of the U-legs 26 and on the approximately circular bottom 27 of the U- Kept in shape.
