Definitions

  • the invention relates to a surface cleaning head having the features of the preamble of claim 1.
  • Such surface cleaning heads can be connected to a source of pressurized cleaning liquid, for example to a high pressure cleaning device.
  • a surface cleaning head according to the preamble of claim 1 is known.
  • the circular loading of the surface to be cleaned leads to surface overlapping of the liquid jets when the surface cleaning head is moved along a working direction. This in turn has a non-uniform cleaning effect.
  • Object of the present invention is to develop a surface cleaning head of the type mentioned in such a way that a surface with glechSystemer cleaning effect can be cleaned in corner and edge areas.
  • the nozzle rotating around the rotation axis only faces the liquid discharge opening along a partial region of its circulating movement. In the remaining area of its circulating movement, the nozzle faces away from the liquid discharge opening. It therefore sweeps over the liquid discharge opening during its orbital motion and can act on the surfaces to be cleaned in strip form with a cleaning liquid jet through them.
  • This has the advantage that the surface is cleaned strip-shaped when the surface cleaning head is moved along a working direction. The distance of the nozzle to be cleaned surface can be kept very low, so that an intense cleaning fluid jet can be directed to the surface.
  • the embodiment of the invention also has the advantage that by means of the surface cleaning head, a large working width can be achieved at a small distance of the nozzle to the surface to be cleaned.
  • Surface overlaps of the cleaning liquid jet, as in the from the DE 102 06 013 C1 known design can not be avoided, in the inventive Design can be avoided.
  • the surface to be cleaned can be uniformly cleaned, with the strongest cleaning effect results in a central region of the surface cleaning head, while in the from the DE 102 06 013 C1 known construction the strongest cleaning effect occurs in an edge region of the surface cleaning head.
  • Another advantage of the surface cleaning head according to the invention is that it can be designed very flat. This is particularly for cleaning edge and corner areas of a surface, for example, for cleaning stairs, a great advantage.
  • the nozzle held on the spray arm is designed as a spot jet nozzle, because this can produce an intensive jet of cleaning liquid which covers the surface to be cleaned in the manner of a strip.
  • the nozzle is non-uniformly acted upon during its rotation about the axis of rotation with cleaning liquid, wherein the largest markets protestkeitsbeetzschlagung takes place in alignment of the nozzle in the direction of the liquid discharge opening.
  • the nozzle is aligned along a partial region of its circulation movement in the direction of the liquid discharge opening, while it faces away in the remaining region of the circulation movement of the liquid discharge opening. It is advantageous if the nozzle can be acted upon with cleaning liquid practically only during its part of the circulation movement facing the liquid discharge opening is while undergoes virtually no cleaning liquid in their remaining orbital motion.
  • the nozzle can be acted upon by a first, the liquid discharge opening facing portion of its orbital motion with a maximum amount of cleaning liquid, while it is acted upon by a second, the liquid discharge opening facing away portion of its orbital motion with a minimum amount of cleaning liquid.
  • it can be provided that it is not at all acted upon with cleaning liquid during its second partial area, that is to say that a cleaning liquid feed to the nozzle is interrupted during the second partial area of the circulating movement.
  • the surface cleaning head has a plurality of spray arms distributed in the circumferential direction, on each of which a nozzle is held, wherein the nozzles are each acted upon in their circulation movement with more cleaning liquid when they face the liquid discharge opening than when it faces away from the liquid discharge opening are.
  • the nozzles rotating together around the rotation axis are always supplied with a larger amount of cleaning liquid when they face the liquid discharge opening.
  • a cleaning liquid supply to the nozzles is sequentially supplied by each of the nozzle with a larger amount of cleaning liquid, which is currently facing the liquid discharge opening, while the liquid discharge opening at this moment facing away from nozzles are supplied with a smaller amount of cleaning liquid, in particular can the latter nozzles the cleaning liquid supply to be completely interrupted.
  • the surface cleaning head has three spray arms with a nozzle distributed uniformly in the circumferential direction, wherein the nozzles can be acted upon with more cleaning liquid over a partial area of at least 120 ° of their circulation movement than over the remaining area of their circulation movement.
  • the nozzles can be acted upon by more cleaning liquid in each case over a partial region of their circulating movement of approximately 130 ° to approximately 150 °, in particular approximately 140 °, than over the remaining region of their circulating movement.
  • Such a configuration has the consequence that the cleaning liquid supply to the rotating nozzles in an overlap region of about 10 ° to about 30 °, in particular about 20 °, simultaneously to two nozzles. This is the case when a first nozzle just leaves its part of the circulation movement facing the liquid discharge opening, while a second nozzle following in the direction of rotation enters this partial area.
  • the at least one spray arm is rotatably supported on a hollow shaft, wherein the hollow shaft has an axial bore which can be brought into fluid communication with a through-bore of the spray arm via a connecting groove extending in the circumferential direction of the hollow shaft only over a partial region. If the spray arm is arranged in the region of the connecting groove of the hollow shaft, then there is a flow connection between the axial bore of the hollow shaft and the through hole of the spray arm. However, the connecting groove extends in the circumferential direction only over a portion of the hollow shaft, so that the flow connection between the axial bore and the through hole is interrupted when the spray arm assumes a position outside of the connecting groove.
  • the circulating around the hollow shaft spray arm is thus supplied unevenly with a circulating motion with cleaning liquid, namely whenever there is a flow connection between the axial bore and the through hole on the connecting groove. Consequently, the nozzle arranged on the spray arm is supplied with cleaning fluid unevenly during its circulation movement.
  • the spray arm is fixed to a bearing element surrounding the hollow shaft.
  • the bearing element can form a sleeve bearing against the hollow shaft, wherein at least its sliding surface can be made for example of plastic, in particular based on a PEEK (polyetheretherketone) material.
  • PEEK polyetheretherketone
  • the bearing element is held by means of ball or roller bearings on the hollow shaft.
  • the hollow shaft is preferably made of brass, bronze or stainless steel.
  • the surface cleaning head of this is connected to a source of pressurized cleaning fluid, for example, to a supply line of a pressurized water supply system or to a pump, in particular a high-pressure pump, and with under Supplied pressurized cleaning fluid.
  • the latter is led to the nozzle via the spray arm.
  • a pressure field builds up, which presses the bearing element in this area from the hollow shaft, wherein at the same time the bearing element is pressed against the hollow shaft on the diametrically opposite side.
  • the hollow shaft is axially offset from the connecting groove surrounded by at least one annular groove.
  • the annular groove allows in the circumferential direction of the hollow shaft pressure equalization and serves at the same time the axial boundary of the unilaterally acting pressure field.
  • the annular groove may be arranged at a small distance from the connecting groove, preferably at a distance less than about 3 mm, in particular at a distance of about 0.5 mm to about 3 mm.
  • an annular groove is arranged in the axial direction on both sides of the connecting groove. It has been found that a particularly stable circulating movement of the spray arm can be achieved by such a configuration.
  • the hollow shaft is axially offset from the connecting groove in the circumferential direction surrounded by a sealing element, preferably of a piston ring.
  • the hollow shaft is surrounded on both sides of the connecting groove by a piston ring.
  • the at least one piston ring is made in a preferred embodiment of a plastic based on a PEEK material, because this allows a particularly smooth rotation of the bearing element.
  • the nozzle of the surface cleaning head according to the invention is oriented obliquely to the spray arm, so that a return pulse is exerted on the nozzle and the spray arm of the dispensed cleaning liquid, due to which the spray arm is rotated together with the nozzle in rotation.
  • the speeds are in a range of about 1,500 revolutions per minute to about 3,000 revolutions per minute.
  • a brake wing is arranged, which increases the air friction of the spray arm and thereby slows down the orbital motion of the spray arm.
  • At least one air supply opening is arranged adjacent to the housing of the brake wing.
  • an "air cushion effect” can be achieved, which facilitates the guidance of the surface cleaning head along the surface to be cleaned by air flows into the housing via the air supply opening and through the liquid discharge opening in the direction of to be cleaned surface emerges from the housing.
  • the braking effect of the brake vanes can be strengthened.
  • the at least one air supply opening is selectively releasable and closable.
  • the air supply opening is infinitely releasable, so that the speed of the spray arm and the buoyancy of the surface cleaning head achieved by the "air cushion effect" can be changed continuously by the user.
  • the surface cleaning head comprises a mechanical cleaning element revolving around the at least one spray arm and penetrating the liquid discharge opening.
  • the mechanical cleaning element By means of the mechanical cleaning element, the surface to be cleaned can be mechanically cleaned.
  • the liquid discharge opening can be used by cross-cleaning bristles. It has been found that the combined use of a cleaning liquid jet and a mechanical cleaning element allows a particularly good cleaning of a surface, in particular a hard surface.
  • the mechanical cleaning element is preferably held on at least one spray arm.
  • a mechanical cleaning element is rotatably mounted axially offset from the spray arm on the hollow shaft.

  • a splash guard is preferably a liquid dispensing opening surrounding bristle strip or a rubber lip used.
  • the use of a flexible splash guard also has the advantage that with its help a mechanical cleaning of the surface is possible.
