Definitions

  • the invention relates to a floor nozzle for vacuum cleaners an air duct, at the rear end of which a roller is connected, a rotating / tilting joint consisting of a connecting piece which can be pivoted into the air duct and an angled tube which is held in the connecting piece so that it can rotate, a suction head with a suction mouth on the bottom, delimited by thread lifters and suction mouth edges, which extends transversely to the suction direction essentially over the entire length of the suction head, wherein either the suction head is movably connected to the air duct by a further tilt joint or a suction mouthpiece is arranged in the suction head so as to be tiltable and wherein the suction mouth has a central section delimited by the thread lifters with a suction opening adjoining the air duct and on each side of the central section a suction channel delimited by the edges of the suction mouth.
  • a floor nozzle of the construction described is from DE-U 298 12 377 known.
  • the suction head by means of a tilt joint on the air duct connected.
  • the suction head contains one vertically movable and operated by a foot switch Bristle holder with bristle strips through the bottom Openings in a base plate of the suction head can be moved in and out are.
  • a foot switch Bristle holder with bristle strips through the bottom Openings in a base plate of the suction head can be moved in and out are.
  • the tiltable on the suction head connected to the air duct adapts Bumps and is independent of the orientation of the suction tube connected to the winding tube always aligned plane-parallel to the floor to be cleaned.
  • a floor nozzle which without Switching mechanism suitable for all floors both for vacuuming Carpet coverings can also be used to vacuum smooth floors is.
  • the suction head is guided on rollers and points a tilting suction mouthpiece that is plane-parallel aligns with the floor covering to be cleaned.
  • the suction mouthpiece consists of a narrow base plate with tub-like molded channel and is pivotable in the Suction head stored. In the direction of suction behind the suction nozzle is always arranged on the floor sealing strip.
  • the suction mouth fits in the described versions uneven floors and is independent of posture and alignment of the suction tube connected to the winding tube aligned parallel to the floor. This allows basically an effective cleaning of the floor surface. on the other hand exists especially with deep-pile carpets there is a risk that the suction mouth will stick to the floor and the pushing force applied during the suction movements must increase sharply. In extreme cases the suction of the floor nozzle leads to unpleasant hopping effects, when they occur, effective cleaning is not is more possible.
  • EP-A 0 302 515 describes a nozzle for vacuuming bedding and Woolen blankets described. It shows one as narrow Slit-shaped suction mouth, being in front and behind roller-shaped hold-down devices are arranged on the suction mouth, the surfaces of which are formed with cylindrical projections are.
  • the publication contains the note that a small slot width of the suction mouth favorably on the Pushing force applied when handling the nozzle must become.
  • a floor nozzle with balanced usage properties must meet numerous, different requirements.
  • the Suction head should be sufficient (transverse to the direction of suction) Have length so that a large floor area with as much as possible little work movements can be cleaned.
  • the suction mouth must also be designed so that fibers and small parts, e.g. Paper clips, shredded paper and the like are added become. In this respect, at least in some areas wide suction opening is useful.
  • the floor nozzle must also have a good dust absorption capacity, that from the center not get worse towards the outer edges of the suction head may. By designing and dimensioning the suction mouth it must be ensured that the entire suction mouth sets the pressure distribution as evenly as possible.
  • the floor nozzle must be designed so that they are moved with little pushing force when vacuuming can and even with deep-pile carpet coverings, where proper operation is no longer possible is excluded.
  • the suction mouth consists of a straight, bottom open channel with parallel to each other arranged suction edges, the distance between them on average about 20 mm is.
  • the width of the Suction mouth from the center of the suction head to the outside, and from about 25 mm to about 10 mm.
  • the suction mouth in the area of its middle section is wider and has a recess which has the rear suction mouth edges in the suction direction interrupts in the area of a suction opening and on the back is bounded by a bridge, to which one with the rear thread lifter equipped with a pocket.
  • the inflow cross-section of the suction mouth on the bottom takes with this configuration considerably.
  • the known floor nozzles are in terms of fiber and Dust absorption largely optimized. Still they are Suction properties are not always balanced as the measures to improve dust and fiber absorption by a greater pushing force can be bought.
  • the invention has for its object a floor nozzle to further develop the structure described at the beginning, that they still have good fiber and dust absorption can also be moved easily on textile floor coverings can and does not even with deep-pile carpets can suck up.
  • the object is achieved according to the invention in that the suction mouth is wider in the area of the central section than in the narrow suction channels adjoining on both sides, and in that the inflow section on the bottom side of the suction mouth, which has a circumference of more than 530 mm, is smaller than 5000 mm 2 . If the limit value according to the invention is adhered to, it is impossible for the floor nozzle connected to a commercial floor vacuum cleaner to get stuck on textile floor coverings. The floor nozzle can be moved with little pushing force.
  • the suction mouth is in the range of the middle section to be significantly wider than in of the sections adjoining on both sides. Surprised dust pickup is not adversely affected if the branches of the suction mouth adjacent to the central section very narrow, so with a very small distance between the suction mouth edges are formed. Also for them The length of the suction head (transverse to the direction of suction) results no restrictions. To comply with the specified on the suction cross-section is correspondingly narrower if the suction head has a long length.
  • the distance between the suction mouth edges less than 16 mm, preferably less than 14 mm.
  • pressure distribution in the suction mouth enhances cross-sectional expansion exhibit. The air flowing into the suction mouth can within the suction mouth with little flow pressure loss derived in the correspondingly wide suction channels become.
  • Suction mouth wider in the area of its central section and has a recess which the in Suction direction rear suction mouth edges in the area of Intake opening interrupts and on the back by a web is limited to the one with the rear thread lifter equipped receiving pocket connects.
  • the two sides the middle section adjoining sections of the suction mouth are accordingly narrow to the limit value according to the invention for the inflow cross section observed.
  • Floor nozzle include an air duct 1, at the a roller 2 is connected to the rear end Swivel / tilt joint 3, which can be swiveled into the Air duct used connector and one in the Spigot angular tube held rotatably, as well a suction head 4 with a bottom-side thread lifter 5 and Saugmundkanten 6 limited suction mouth 7, which is transverse to the direction of suction essentially over the entire length of the Suction head 4 extends.
  • the suction head 4 is by a Another tilt joint 8 movable on the air duct 1 connected and depends on the Alignment of one connected to the rotary / tilt joint 3 Suction pipe always parallel to the one to be cleaned Floor area.
  • the suction mouth 7 is one of the Thread lifters 5 limited middle section 9 with a Air duct connecting intake 10 and on either side of the middle section 9 each one of the Has suction mouth edges 6 limited narrow suction channel 11.
  • the suction mouth 7 is in the region of its central section 9 broader and e.g. a recess 12, which the suction mouth edges at the rear in the suction direction Area of the intake opening interrupts and on the back of a web 13 is limited to which one with the rear Thread lifter 5 equipped receiving pocket connects.
  • the front and rear suction mouth edges 6 in the suction direction are arranged in parallel, the distance between the suction mouth edges being less than 16 mm.
  • the channel-shaped section 11 of the suction mouth 7 can, as shown in FIG. 3, have a substantially rectangular cross section.
  • the aim is an even pressure distribution in the Suction channel.
  • Fig. 4 have the adjoining on both sides of the central section Suction channels 11 of the suction mouth 7 above the suction mouth edges 6 a cross-sectional widening which promotes the pressure distribution in the suction mouth on.
  • the distance between the Saugmundkanten 6 is smaller than that above the Suction mouth edges measured width of the incoming air laxative channel.
  • the design enables a very uniform pressure distribution along the suction mouth edges 6.
  • the area of the inflow cross-section succeeds to keep small what is favorable to the Pushing force of the suction head affects.
  • Pressure difference and air flow are in the floor nozzle measured.
  • Canister vacuum cleaners become even more effective Air performance used, the inflow cross section of the Suction mouth can be reduced.
  • the appropriate value is based on fewer attempts can be determined.
