Definitions

  • the invention relates to a cleaning device for window surfaces, facade surfaces, etc., with a cleaning head with at least one cleaning chamber, to which a cleaning liquid is supplied, which is sucked back into a container from at least one suction area of the cleaning head.
  • the associated units such as water tank, energy generator, pump etc. are located on the frame.
  • the frame can be moved horizontally and vertically along the facade or a window surface by a control device without the invention being restricted to these directions. It can also be provided that the cleaning head is guided over the surface by an operator.
  • the frame is usually slidably mounted in one direction, for example the vertical direction, on a guide rail, while this guide rail is arranged, for example, by means of two slides, on two guide rails which run perpendicularly thereto, that is to say horizontally.
  • the cleaning head can have a fairly large range of motion, so that the suction line leading to the water container must be correspondingly long. So far, this suction line has been formed by hoses which, on the one hand, have a considerable weight, which must be moved when the cleaning head is moved, and, on the other hand, interfere spatially and optically due to their presence.
  • the present invention has for its object to provide a better solution to this problem.
  • the invention provides that the suction area of the cleaning head is connected via a line to a boat which is moved in accordance with the movement of the cleaning head and which slides along a perforated wall section of a suction channel device connected to the liquid container, with the spreading of sealing lips which slide the perforated wall section cover and seal the suction channel to the outside.
  • perforated includes all suitable wall openings such as an elongated slot.
  • a short line for example a short hose and the so-called boat
  • a boat sliding along the suction channel and introducing the extracted liquid / dirt particle / air mixture through the holes into the suction channel .
  • the suction channel can be held stationary, for example on a lift basket which also carries the liquid container with which the suction channel in Connection is established, or a section of the suction channel can also be moved together with the boat, as will be explained in more detail below.
  • the cleaning head is guided by at least one guide rail during its movement over a surface to be cleaned, for example a window surface, which, according to a further essential aspect of the invention, is designed as a tube which is a component of the suction channel.
  • the guide tube or preferably the guide tubes preferably have a rectangular cross section.
  • a preferably approximately roof-shaped perforated sheet device is attached to an outside of the guide tube or the guide tubes, which are components of the suction channel device, which is covered on both sides by rubber lips, the free end portions of which protrude beyond the perforated sheet and where that The boat is not in contact due to the negative pressure in the suction channel.
  • the perforated sheet device does not necessarily have to have a roof shape.
  • perforated plate includes a wall with many openings through which the sucked-in liquid / dirt particles / air mixture can pass in the area of the boat and in the other areas the negative pressure of the suction channel acts on the rubber lips above it so that it Attach the system to the perforated plate and seal it with its end sections.
  • the wall of the guide tube, which is fitted with the approximately roof-shaped or A-shaped perforated plate direction is also provided with numerous breakthroughs, so that the liquid dispensed by the boat reaches the inside of the guide tube and is transported there to the container.
  • the suction channel device thus consists of the guide tube, which guides the cleaning head or its frame by means of a guide device in the horizontal or vertical direction, of the riveted, essentially roof-shaped perforated plate arrangement, for example, and the sealing rubber lips, which are only opened where the boat is located .
  • the boat has a V-shaped cross-section which corresponds to the roof shape of the perforated plate device.
  • the boat can be a solid plastic body which is penetrated by one or two bores to which hoses connected to the suction area of the cleaning head can be attached, the bores opening into the V-shaped recess so that the liquid / dirt particles / air Mixture hits the perforated sheet device and passes through it.
  • the boat can be attached to the holder of the cleaning head, which also carries the guide device with which the holder (together with the cleaning head) is slidably seated on the guide rail. So that the boat can be moved smoothly, it is expediently held such that it is guided at a small distance from the perforated sheet device, and during its movement it opens the rubber lips which immediately close again behind the boat as a result of the negative pressure.
  • the shuttle has sinusoidal side contours in the longitudinal direction, which give the entire introduction area of the air / dirt particle / water mixture such a good homogeneity and consistency that Leaks can be practically ruled out.
  • the sealing lips lie perfectly close to the sinusoidal outer contours of the boat and close immediately in front of and behind the boat. This means that no water can escape from the suction channel.
  • the cleaning head (with its holder) is guided both in the horizontal direction and in the vertical direction on guide rails or, according to the invention, on guide tubes. If, for example, the cleaning head with its holder is slidably seated on a vertical guide tube, the extracted liquid / dirt particle / air mixture is introduced into the vertical guide tube via a boat attached to the holder, which is part of the suction channel.
  • the vertical guide tube When moving in the horizontal direction, the vertical guide tube is guided on two horizontal guide rails, for example by means of two slides. It is provided according to the invention that at least one of these guide rails is designed as a hollow guide tube, which in turn is part of the suction channel and is therefore provided on one long side with a roof-shaped perforated sheet device which is covered by the sealing lips mentioned above.
  • a shuttle in the area of the carriage, a shuttle is in turn connected to the vertical guide tube or suction channel via an associated line, wherein this shuttle can slide over the roof-shaped perforated plate device of the horizontal guide tube, under its sealing lips. In this way, a connection is created between the vertical section of the suction channel and the horizontal section of the suction channel.
  • the liquid / dirt particle / air mixture is converted from the horizontal suction channel in a suitable manner, ie for example via a connected hose. discharged into the liquid container, which for this purpose can be connected in its upper region to a suction fan, which creates the negative pressure in the entire suction channel.
  • the shape of the boat or boats according to the invention ensures that the rubber lips always close the suction channel so tightly that no liquid can escape from the suction channel during water suction. There is no need to carry long and bulky hoses, and the design effort for arranging the suction channel is relatively low, since in the cases in which the cleaning head or its holder or frame is guided on guide rails, these guide rails are used as the main component of the suction channel.
  • Figure 1 is a guide rail system for the cleaning head of an automatic cleaning device in a front view.
  • FIG. 2 shows the guide rail system according to FIG. 1 in a side view
  • FIG. 3 shows the connection area of a cleaning head to a suction channel

  • Figures 1 and 2 show in a largely schematic manner a frame 1 which hangs on ropes 2 on a building facade, not shown, the ropes 2 being attached to the frame 1 by means of adapters 3.
  • a frame, not shown, can be attached to the frame 1, from which water is supplied to a cleaning head 6, which is then sucked back into the water container.
  • the frame 1 is provided with rigid support legs 4, the ends 5 of which are guided in vertical guide rails which are fastened to the building facade or embedded therein.
  • the invention is not limited to such a guidance of the frame 1 on such a building facade.
  • the cleaning head 6 is fastened to a pneumatic piston / cylinder arrangement 7 with which the cleaning head 6 can be pushed forward along the Y axis in contact with a window pane to be cleaned.
  • the backward movement can take place due to the weight of the cleaning head.
  • a pneumatic piston / cylinder arrangement instead of a pneumatic piston / cylinder arrangement, another suitable drive device can also be provided.
  • the guide rail 9 is in turn held by two carriages 10 which are displaceably seated on two horizontally running guide rails 11, which are designated as the X axis in the figures.
  • deflection rollers At the ends of the guide rails 9 and 11 there are deflection rollers, not shown, over which a drive belt runs, the ends of which are fastened to the slide 8 and the slide 10, respectively.
  • the belts are driven by a drive motor 12 or a drive motor 13. As a result, the cleaning head 6 is moved in the vertical and horizontal directions over a window pane to be cleaned.
  • the guide rail 9 is a rectangular guide tube 14, the upper wall in Fig. 3 is connected to an inverted V-shaped or roof-shaped perforated plate 15.
  • the perforated plate 15 is covered by rubber or a rubber-like material, on both sides sealing lips 16, the end portions 17 projecting beyond the roof-shaped perforated plate 15 abutting one another in the regions in which there is not a so-called boat 18.
