Definitions

  • the invention relates to a washing-suction or damp-wiping-suction cleaning brush with at least two bristle rings, at least one tube loop enclosed by a bristle ring with spray nozzles for spraying out the washing or cleaning liquid and at least one suction channel open at the bottom for suctioning off excess washing or Cleaning liquid, dirty liquid and possibly unhumidified dirt particles.
  • the known brushes of this type are pure washing-suction-cleaning brushes and are neither intended nor suitable for being usable either for the wet or for the dry cleaning of a variety of surface materials and structures. In particular, they are not a universally applicable cleaning instrument, for example for cleaning large-capacity vehicles for passenger transport, including their metal, plastic, wooden or carpeted floors, seat and wall coverings, wall and ceiling cladding, luggage racks and the like, and other facilities that need to be cleaned or routinely cleaned.
  • the possible uses of the known washing-suction-cleaning brushes are each limited to a narrow area of application and cannot be applied to a generally possible washing-suction or damp wiping-suction cleaning of many smooth or structured, hard or soft, flat, curved or angular surfaces extend.
  • a brush which essentially has a tapered housing with a terminal suction nozzle and on the underside of a spray tube loop bordered by two rows of bristles with very close-fitting bristles with vertically downwardly directed spray nozzles for the washing or cleaning liquid having.
  • the bristles of the two spray tube surrounding rows of bristles are comparatively short and converge downward in a V-shape, so that the bristles of both rows touch and the spray tube sprays against the lowest part of both rows of bristles.
  • the interior of these two rows of bristles defines a central suction channel that is open at the bottom; the outer of these two rows of bristles and a further, peripheral row of bristles enclose a peripheral suction ring channel which is also open at the bottom.
  • the tips of all bristles are in the same plane.
  • the nozzles of the spray tube spray the treatment liquid with a constant but adjustable delivery rate to the bottom of the V-space formed by the two rows of bristles surrounding the spray tube, whereupon the liquid with the brush resting on the cleaning surface and with the brush lifted off without dripping via the suction channels or - channels in the suction nozzle.
  • the different fluid flow is explained as follows.
  • the air suction flow is at a maximum and sufficient to suck the liquid sprayed against or into the V-standing rows of bristles laterally through these rows of bristles over their bristle front into the suction channels without liquid dripping downwards.
  • the air suction flow is lower because the dense bristle rings oppose the sucked-in false air and provide a flow resistance.
  • the suction flow conditions set themselves automatically when the spraying and suction power is matched to one another in such a way that when the brush is lying on top, i.e.
  • the brush for washing-suction operation only works optimally according to its capabilities if it is held parallel to the processing surface. In the case of an inclined support, the brush would only lie partially, so that undesirable suction conditions would occur.
  • this known brush allows processing of the documents to be cleaned only with the bristle tips, so that disadvantageous line patterns can remain on smooth surfaces in wet operation.
  • a device for the washing-suction cleaning of facades, walls, ceilings, escalators and floor coverings which is characterized by a rubber sleeve surrounding the washing-suction head and resting on the surface to be cleaned.
  • the cuff serves to limit the expansion or to hold the liquid that has reached the surface under the device head.
  • the washing-suction-cleaning brush according to DE-PS 16 28 468 permits the wet processing of curved surfaces, the area of application of the latter suction-cleaning head is limited to flat surfaces, which, however, can be corrugated like escalators.
  • the object of the invention is to have a washing-suction or damp-wiping-suction cleaning brush available, which can be used for flat, curved and also rastered cleaning surfaces made of any brushable material at all can be used dry and moist; whose bristles are not partially lifted from the base when the brush position is inclined; which either allows manipulation of the surface to be cleaned with only long, flexible bristles without manipulation of the brush, the surface with the long sides of the bristles, that is to say with a part of the total Bristle body is brushed off, or processing with long and short bristles is permitted, so that the cleaning surface is also treated with bristle tips; and in which the application of cleaning liquid to the items to be cleaned can be varied without regulating the set spraying power.
  • the washing-suction or damp-wiping-suction cleaning brush has: a peripheral bristle ring set with comparatively long bristles that widens downward in a funnel-like manner and is composed of at least two bristle rings lying one against the other, the bristle tips of which form bristle fronts, wherein the bristle length decreases from the innermost bristle ring to the outermost bristle ring, - Of two adjacent bristle rings, the bristle front of the outside bristle ring lies above the bristle front of the inside bristle ring and -
  • the bristles of all of the funnel-like widening bristle rings are coordinated with one another in terms of their rigidity so that when the funnel opening of the bristle rings is widened when the brush is pressed on and moved on a cleaning pad of two adjacent bristle rings, the outer bristle ring serves as a holder for the inner bristle ring and on
  • a cleaning brush according to the invention preferably, and as characterized in claim 2, also has a central bristle set with comparatively short bristles, the bristle fronts of the respective bristle arrangements being assigned to one another with respect to the unused brush in such a way that the bristle front at least of the innermost of the bristle rings of the peripheral bristle ring set lies below the bristle front of the central bristle set and the bristle front of the outer peripheral bristle ring, or in the case of more than two peripheral bristle rings, the bristle front of at least the outermost bristle ring does not lie below the bristle front of the central bristle set.
  • the central bristle set is permeable in such a way that a part of the suction stream can flow through it; furthermore, an annular space is formed between the central bristle set and the peripheral bristle ring set, through which the remaining part of the suction flow reaches the suction nozzle; finally there is a sprayer for spraying washing or cleaning liquid into the central bristle set.
  • the washing-suction or damp-wiping-suction cleaning brush 1 has a suction nozzle 2 which also serves as a brush head and to which a central bristle set 3 and a peripheral bristle ring set 4 which widens downwards in a funnel shape are connected.
  • the central bristle set 3 like the peripheral bristle ring set 4, can be circular in cross-section or preferably oval to elongated and are approximately oval in the example shown, the two ovals being symmetrical to one another.
  • the peripheral bristle ring set 4 consists of two bristle rings 5, 6.
  • the bristle tips or the bristle front 7 of the inner bristle ring 5 protrude beyond the bristle tips or the bristle front 8 of the central bristle set 3, while the bristle tips or bristle front 9 of the outer bristle ring 6 above the Bristle front 8 ends.
  • the brush 1 contained only a bristle ring 5 with regard to its peripheral bristles, it would not yet be suitable for the intended washing-suction or wet-wiping-suction operation, since the initially closed, funnel-shaped one moves back and forth on the cleaning surface Open the bristle wall of the tightly placed bristle ring 5 and would cause undesirable air intake or air flow conditions, as will be explained below.
  • the functional brush 1 does not suction liquid on the cleaning surface below the brush in such a way that this liquid is removed from the wet surface by the suction flow and immediately into the Suction nozzle 2 would be torn away, but on the way that the liquid with the sucked-in air flow rises at the peripheral bristles and is torn from its support at about the level of the annular gap 12 formed between the bristle ring 5 and the central bristle set 3 and entrained in the suction nozzle 2 .
  • FIG. 1 the line 13 symbolizes the cleaning pad and the liquid track 14 and the arrows assigned to this track the liquid flow and its direction.
  • a prerequisite for the above-mentioned liquid path is not only a sufficiently strong air flow rising on the inside of the bristle funnel, but also a distribution of the air flow as evenly as possible over the circumference of the inner wall of the bristle funnel. If the bristles of the peripheral bristle funnel are more or less uniformly dense and the bristle wall is closed, the flow conditions are optimal in the sense that the flow velocity of the sucked-in air entering through the peripheral bristle wall has its highest values along the inside of the bristle wall, no significant along the circumference Shows inhomogeneities and is comparatively low in the center at the bottom of the brush.
  • a brush 1 now which would consist solely of the bristle ring 5 with respect to the peripheral bristle funnel, would behave in such a way that the bristle wall 5 would behave in a straightforward or circular working motion when the contact pressure was already gentle when going back and forth on the base 13
  • the frictional resistance and the flexibility of the bristles with the formation of gaps or gaps in the A-shape that widen from top to bottom, it opens in several places, most notably on the respective movement front.
  • the outside air collapsing through these gaps then led to particularly strong air flows in the area to the side of the gaps and to an increased air flow in the center of the brush, whereas an air flow upwards at the gaps opposite areas of the bristle wall would be weak.
  • the one goal of the invention would not be achieved to operate the same brush either with only long bristles or additionally with short bristles, because for the central bristle set 3 to come down, the bristle ring 5 must necessarily be able to widen what a rubber sleeve is too inelastic or too inflexible edging would have to prevent.
  • the bristle ring 5 which has bristles on the outside of the bristle ring 5, serves as a triple advantage for the bristle ring 5, the bristles of which are shorter and stronger and thus stiffer than the bristles bordered by it.
  • the bristles of the bristle ring 6 enter between those of the bristle wall 5, so that the bristles of the rings 5 and 6 penetrate one another, the bristles of the ring 6 standing overall steeper than the bristles of the ring 5.
  • the A-gap formation in the peripheral bristle wall described above does not occur.
  • the second advantage associated with the bristle ring 6 is that when the brush 1 is pressed on violently, the tips of the bristles of the bristle ring 6 are brought to the cleaning surface and there an additional front 9 of bristle tips acts on the cleaning surface in addition to the bristle front 8 of the central bristle set 3.
  • the third advantage of the bristle ring 6 is that it compensates the wall thickness, which in absolute terms when the funnel of the bristle wall 5 expands under the operating contact pressure of the brush 1, is compensated for by the filling with its bristles, which is becoming increasingly weaker, so that otherwise unfavorable that may arise Air inflow conditions remain avoided.
  • a cleaning brush 1 provided as a light hand-held device has approximately the relative dimensions according to FIGS. 1 and 2, the opening funnel of the bristle ring 5, as shown in FIG. 1, measuring approximately 12 to 15 cm in its greatest width .
  • the bristles of the peripheral bristle ring 5 do not run in a straight line, but instead are bent over, with the bristle, more preferably, being designed as a double strand with a lower loop.
  • the continuity of the bristle wall 5 has been found to be particularly stable, which may not least be due to the fact that a tuft of bristles of the bristle ring 6 between a double strand of bristles of the bristle ring 5 doubles the double bristle in two Support directions against a deflection in the circumferential direction of the peripheral bristle funnel.
  • the bristle ends stand up in the form of an arc or a loop, less point-like contact is formed between the bristle and the cleaning surface, but desirably more a surface-like contact.
  • the peripheral bristle ring set can in principle also be composed of three or more bristle rings instead of two, in which case a bristle ring which is in each case adjacent to a bristle ring under consideration serves as the holder for the enclosed ring and these rings cooperate in the manner described for wreaths 5 and 6.
  • a bristle ring which is in each case adjacent to a bristle ring under consideration serves as the holder for the enclosed ring and these rings cooperate in the manner described for wreaths 5 and 6.
  • the bristle front of an outer peripheral bristle ring lies above the bristle front of the inner peripheral bristle ring, the bristle front of the outermost peripheral bristle ring should not lie below the bristle front of the central bristle set 3.
  • the peripheral spray pipeline 11 which, as in the example, deflects the bristles of the peripheral bristle ring 5 above into the funnel shape of the bristle ring 5 (which would then not have to be provided in the case of bristles which are already inserted at an angle), has in its lower region a multiplicity of spraying obliquely against the bristle ring 5 Nozzles 15 to spray the washing or cleaning liquid on.
  • the spray pipe 11 is designed as a ring line and is fed via the feed line 16 with a manual control valve 17.
  • the peripheral spray pipeline 11 and the central spray device 10, 10 ⁇ are jointly supplied by the feed line 16, the feed piece opening into the peripheral ring line 11 itself forming the spray pipe 10 and being part of the central spray device.
  • the central spraying device is completed by a spray pipe 10 ⁇ emerging blindly from the peripheral ring line 11.
  • the two spray gates 10, 10 ⁇ of the central spray device have a plurality of spray nozzles which spray obliquely downwards against the bristles of the central bristle set 3, the distance between the spray tubes 10 and 10 ⁇ from one another and their spray directions being dimensioned such that the application is as uniform as possible the bristles of the central bristle set 3 come about.
  • the bristle set 3 here consists of a bristle ring 18 and rows of bristles 19 positioned at an angle to the longitudinal or transverse axis of the brush 1.
  • a wet wipe suction or wash-suction cleaning brush 1 according to FIG.
  • the invention has two separate or separately controllable spray systems for moistening the central bristle set 3 and the peripheral bristle ring set 4, which makes it possible, for example, to operate only the peripheral spray device 11.
  • the advantage which can be achieved in this way is explained in the course of the following detailed explanation of the spray device 11 clearly.
  • both spray devices normally spray, the central spray device 10; 10 ⁇ , as described above, sprays against the bristles of the central bristle set 3 and the peripheral spray device 11 against the bristles of the inner or innermost peripheral bristle ring 5, the spray nozzles 15 of the peripheral ring line 11 being directed approximately towards the lower third of the height of the bristle ring 5 are (spray point 20 according to FIG. 1).
  • the brush 1 lies on the cleaning surface, be it with or without the central bristle set 3 standing up, as already explained above, there is a lower air intake and exhaust flow, which is lowest in the brush center and its highest flow rate on the inner wall of the peripheral Bristle ring 5 developed.
  • the liquid sprayed into the central bristle set 3 can reach the surface and act on it. Furthermore, it also reaches the bristles of the peripheral bristle ring 5 sprayed liquid to the base.
  • the liquid that has got onto the base is suctioned off in such a way that the brush 1 is used and handled not in static rest but in motion.
  • the brush 1 is moved over the cleaning surface, in particular with a circular working movement, circumferential compaction and thinning of the thickness of the bristle wall occur along the circumference of the peripheral bristle ring set 4 lying thereon. According to the approach, this is a similar effect as in the A-gap formation described above, without such gaps actually occurring because of the bristles of the bristle ring 6 lying on the outside between the bristles of the peripheral bristle ring 5.
  • the central spraying device 10, 10 ⁇ is not and only the peripheral spraying device 11 is in operation, it is possible to vary the degree of moistening or wetting of the brush 1 on the cleaning surface without manipulation of the metering device 17.
  • the spray device 11 sprays against the lower part of the peripheral bristle ring set 4.
  • the point of impact 20 of the spray liquid on the bristles of the peripheral bristle ring set 4 moves further and further downwards until it is lost in the limit case, after which the liquid immediately hits the base.
  • the effect occurs that the resulting air flow, which rises on the inner wall of the peripheral bristle ring set 4, becomes increasingly ineffective as the impact point 20 of the sprayed-out liquid falls progressively lower, so that the sprayed-out liquid is immediately sucked off again, so that the brush 1 depending on the degree of deflection of their peripheral bristles allows operating conditions between completely or almost dry to a more or less moderate wetting of the surface to be treated.
  • the completely dry operated or only moistened or very mildly spraying brush 1 according to the invention has its advantages, in particular in the dedusting of objects which do not have a continuous surface, but instead have grids, edges, webs, struts and the like, for example as in luggage racks in Shape of grids or nets.
  • the brush 1 allows suction.
  • the long and comparatively thin and resilient bristles of at least the inner (st) en peripheral bristle ring 5 act like a brush with which the dust lying thereon can be whirled up and sucked off synchronously.
  • the brush of the invention works here so to speak as a suction brush.
  • a brush 1 according to the invention can also be used reliably in a position inclined to the level of the cleaning surface. Accordingly, edges and even corners of objects can be well enclosed with a brush according to the invention and, in accordance with the liquid and air flow conditions described, can be subjected to a wiping and a more brushing cleaning treatment as well as flat or curved, continuous or surface-structured in accordance with the liquid and air flow conditions described Surfaces.
  • the central bristle set 3 can have any other bristle arrangement instead of, as shown and described for the example, it being possible to provide bristle rings 18 which are concentric with the bristle ring 18 instead of rows of bristles 19.
  • the invention also provides for the central bristle set 3 to be arranged as an exchangeable unit in the suction brush, which at the same time gives the possibility of using bristle sets 3 of different bristle length and hardness for more or less robust scrubbing of the surface to be cleaned.
  • peripheral bristle ring set 4 should be exchangeable for variation of the bristle work or for reasons of replacement, for which purpose a screw connection in the form of an internal thread of the bristle ring frame and an external thread of the suction connection 2 can be selected for bristle ring sets 4 and an oval cross section for bristle ring sets and adapted suction port 2 offers, for example, a clamp closure for the quick change of a peripheral bristle ring unit.
  • a washing-suction or damp-wiping-suction cleaning brush without a central bristle set 3 also fulfills the task, including a cleaning surface optionally with soft-wiping bristle bodies or additionally with harder attacking bristle tips to edit. If one assumes a brush according to FIG.
  • such a brush acts as a soft sweeping suction brush with a softer contact pressure due to the bristles of the bristle ring 5 which are still moderately bent outwards, while with a stronger contact pressure the between then, when the funnel opening of the inner bristle ring 5 widens further, the bristles of the inner bristle ring 5 engage the bristles of the bristle ring 6 with their bristle tips as far as the cleaning base.
  • the brush can also be used without a central set of bristles 3 without dripping, provided that no central spraying device is provided or such is out of action.
