Definitions

  • the invention relates to an automatic window cleaning system, in particular for the windows of a tall structure such as a skyscraper.
  • the invention can also be used for the automatic cleaning of facade surfaces or the like.
  • Automatic window cleaning systems have been proposed for cleaning the windows of tall structures, which have a cable-suspended nacelle on which a cleaning head is attached, which is guided by a control device over the window surfaces.
  • the associated components of the cleaning system such as water tanks, energy generators, drive devices for the cleaning head, lines, etc., are located on the nacelle.
  • the nacelle for example, is suspended from a crane that can be moved on rails that are located on the roof of the housing. The crane moves the nacelle from window to window in order to carry out a cleaning process there.
  • the cleaning head is supplied with water from an associated water tank by means of a pump, which is sucked out of the cleaning head together with the dirt and sucked-in air removed from the pane after the cleaning process.
  • the dirty water / air mixture is taken up in a separate dirty water container and must be disposed of later.
  • a disadvantage of such a window cleaning system is that a large supply of clean water has to be provided on the nacelle and that the drained dirty water also requires a large container, so that the lift cage has considerable dimensions and a large weight.
  • the present invention has for its object to provide an automatic window cleaning system that works with lower water consumption.
  • the cleaning head of the window cleaning system contains at least one cleaning chamber, at least one suction chamber and at least one air supply chamber, and that these chambers are connected to a closed air and water circuit via lines, preferably in the form of hoses.
  • a closed air and water circuit via lines, preferably in the form of hoses.
  • a water tank is installed in the air and water circuit, which contains a dirty water chamber and a chamber for clean water, hereinafter referred to as pure water chamber.
  • a common container can be divided by a partition, which, however, preferably does not subdivide the interior into two completely separate chambers, but only extends up to the vicinity of the upper wall of the water container, so that an interconnected, common space over both chambers for the air that is sucked out of the cleaning head together with the dirty water.
  • two separate containers can be arranged for receiving the dirty water and the clean water.
  • the at least one suction chamber of the cleaning head is connected to the dirty water chamber of the water container via a line, for example a hose.
  • a line for example a hose.
  • the cleaning head can also have a plurality of separate suction chambers or a plurality of front suction regions which are separate from one another and which open into a common rear suction chamber of the cleaning head.
  • the dirty water chamber of the water container is expediently connected to the pure water chamber via a line in which a pump and a filter device are arranged, in which the polluted water is cleaned before it reaches the pure water chamber.
  • the pure water chamber is connected to the at least one cleaning chamber of the cleaning head via a line provided with a pump, which can also have a plurality of separate cleaning chambers into which the windshield washer water is introduced.
  • a pump which can also have a plurality of separate cleaning chambers into which the windshield washer water is introduced.
  • the dirt located on the disks is removed, for example by ultrasound, mechanically by rotating brushes or by water vapor, the dirt being mixed with the water or water vapor and then suctioned off together with it.
  • a suitable steam generating device is arranged in the line leading to the cleaning chamber.
  • the air and water cycle is completed by the fact that the upper air space of the water container is connected via a line to the at least one air supply chamber of the cleaning head, this line being provided with a blower device which continuously sucks the air out of the water container during operation of the window cleaning system and to the air supply chamber on the cleaning head.
  • This closed air circuit prevents water loss that would occur if the air drawn off with the dirty washing water were released into the environment. The reason for this is that the air drawn off with the dirty washing water is 100% saturated with water, while fresh air drawn in from the surroundings would have a considerably lower air humidity. Would the air sucked in with the wash water be constantly removed from the system and fresh air sucked into the water supply system through the cleaning head would result in a constant considerable water loss, which is avoided by the closed air circuit provided according to the invention.
  • the at least one air supply chamber encloses the cleaning head.
  • This air supply chamber can surround the cleaning head as an outer annular channel, to which a likewise annular suction space can adjoin radially on the inside.
  • the invention is not limited to this design; rather, suction areas distributed over the entire cleaning head can be provided.
  • the at least one air supply chamber surrounding the cleaning head is delimited by an outer wall which at least partially consists of a thin-walled, elastic material.
  • the thin-walled elastic material also makes it possible to clean the edge region of a pane, since the elastic outer wall of the air supply chamber can be deformed when the cleaning head is guided to the pane frame so that it lies against the outer wall of the suction chamber of the cleaning head. This does not affect the suction process, since sufficient air is still sucked into the suction chamber from the other peripheral areas of the cleaning head.
  • Either the entire outer wall of the air supply chamber can consist of the thin-walled elastic material or a wall strip, for example 30 mm deep, measured from the surface of the pane in the direction of the rear of the cleaning head.
  • the air supply chamber resumes its original shape due to the elastic material of its outer boundary wall.
  • the air / water circuit provided according to the invention makes it possible to supply the cleaning head of the automatic window cleaning system with a small amount of water with the water required for the cleaning process and to suction and clean the contaminated water again.
  • clean water is always supplied via hoses by means of a pump to the at least one cleaning chamber of the cleaning head, the cleaning effect being able to be increased if the panes are expected to become very dirty by installing an electrically heated instantaneous water heater between the pump and the at least one cleaning chamber to heat the water.
  • a suitable steam generator device is provided.
  • the dirt is removed from the disk with the aid of water or steam, e.g. detached by ultrasound.
  • the water enriched with dirt flows from the at least one cleaning chamber into the at least one suction chamber of the cleaning head and is fed to the dirty water chamber of a two-chamber container via hoses via a hose.
  • the airflow is generated by a blower that Sucks air out of the two-chamber container and feeds it through a further hose to the at least one air supply chamber on the cleaning head.
  • This closed air circuit prevents - as already explained in detail above - the constant removal of water vapor from the water supply circuit.
  • the cleaning head designated as a whole by the reference number 1, contains a cleaning chamber 2, a suction chamber 3 encircling the cleaning chamber 2 and an air supply chamber 4 encircling it in turn.
  • a two-chamber water tank 5 of the water supply device contains a chamber 6 for clean water and a dirty water chamber 8 divided by a partition 7 inside the water tank 5.
  • the partition 7 ends below the upper end wall 9 of the water tank 5, whereby above the water level 10 of the clean water and the water level 11 of the dirty water creates a common air space 12 in the water tank.
  • the pure water chamber 6 of the water tank 5 is connected to the cleaning chamber 2 of the cleaning head 1 via a line 13.
  • a pump 14 pumps clean water through a continuous-flow heater 15 into the cleaning chamber 2, which cleans the surface of a disk 16 facing it. This can be done for example by ultrasonic energy that is transferred from one to the bottom of the cleaning ⁇ supply chamber arranged ultrasonic generator with the result of the cleaning fluid that by cavitation occurring all dirt particles quickly and effectively from the Disks 16 are solved.
  • the cleaning can also be carried out, for example, by means of the excessively supplied water vapor, for which purpose the cleaning chamber on the front side expediently contains several steam cleaning chambers enclosed by webs and the water vapor between the front edges of the webs and flows through the disc surface into the suction chamber or a plurality of suction areas of a common suction chamber. This steam flow also reliably cleans the pane 16.
  • Rotating brushes for example, can also be arranged in the cleaning chamber, with which an effective cleaning process can take place.
  • the washing water which has meanwhile mixed with the detached dirt particles, is sucked into the suction chamber 3, together with air from the radially outer air supply chamber 4.
  • the air / water / dirt mixture is fed into the dirty water chamber 8 through a line 17 of the water tank 5 promoted, which can be done if necessary with a pump, which is not shown in the figure.
  • This suction process can also take place through the action of a blower 18, which is arranged with its motor 19 in a line 20, which connects the air space 12 of the water tank 5 with the air supply chamber 4 of the cleaning head 1.
  • the dirty water chamber 8 is connected via a further line 21 to the pure water chamber 6 of the water tank 5, a pump 22 with an associated motor 23 and a filter circuit 24 being arranged in the line 21.
  • this filter circuit 24 the water is freed from the pollution picked up by the cleaning process.
  • the air entering the suction chamber 3 from the air supply chamber 4 comes so intensely into contact with the water on its way into the air space 12 of the water tank 5 that it becomes 100% saturated with water.
  • This air, which is completely saturated with moisture, is fed back to the air supply chamber 4 according to the invention, whereby a closed water-air circuit is formed in which water loss is avoided, which would occur if saturated air were always released to the environment and fresh air was sucked into the water supply system.
  • the air supply chamber 4 is delimited by an outer wall 25, which consists of a thin-walled elastic material in the edge region adjacent to the pane 16.
