Description
Die Erfindung betrifft eine Reinigungsvorrichtung, insbesondere für Glas- und Fassadenflächen, mit einem Reinigungskopf mit wenigstens einer Reinigungskammer, der aus einem Behälter Reinigungsflüssigkeit zugeführt wird, die von einer Unterdruckeinrichtung wieder abgesaugt wird.The invention relates to a cleaning device, in particular for glass and facade surfaces, with a cleaning head with at least one cleaning chamber, the cleaning liquid from a container is supplied by a vacuum device is suctioned off again.
Die Reinigungsvorrichtung kann vollautomatisch ausgebildet sein und z.B. zur Reinigung der Fenster- und Fassadenflächen von Hochhäusern verwendet werden. In diesem Falle kann der Reinigungskopf beispielsweise an einer an Seilen hängenden Gondel befestigt sein und durch eine Steuereinrichtung über die zu reinigenden Flächen geführt werden. Auf der Gondel befinden sich dann auch die zugehörigen Bestandteile der Reinigungsanlage wie Wassertanks, Energieerzeuger, Antriebseinrichtung für den Reinigungskopf, Leitungen etc. Die Gondel kann an einem Kran aufgehängt sein, der auf Schienen verfahrbar ist, die sich auf dem Dach des Gehäuses befindet, wobei die Gondel von dem Kran von Fenster zu Fenster verfahren werden kann, um dort jeweils einen Reinigungsvorgang auszuführen. The cleaning device can be designed fully automatically and e.g. for cleaning the window and facade surfaces of Skyscrapers are used. In this case, the cleaning head for example on a gondola hanging on ropes be attached and by a control device on the cleaning surfaces. Are on the gondola then the associated components of the cleaning system such as Water tanks, energy generator, drive device for the cleaning head, Lines etc. The nacelle can be hung on a crane be movable on rails that are on the Roof of the housing is located, the nacelle being lifted by the crane Window to window can be moved to one at a time Carry out cleaning process.

Die Reinigungsvorrichtung muß aber nicht vollautomatisch ausgebildet sein, sondern es kann sich hierbei auch um eine halbautomatische Vorrichtung handeln, bei der z.B. der Reinigungskopf von einer Bedienungsperson über die zu reinigenden Flächen geführt wird, während die Reinigungsfunktion des Reinigungskopfes automatisch abläuft. Dies bedeutet, daß dem Reinigungskopf von einer Pumpe die Reinigungsflüssigkeit zugeführt wird und daß die in dem Reinigungskopf vorgesehenen Reinigungsmittel selbsttätig arbeiten, wobei es sich bei diesen Reinigungsmitteln beispielsweise um an der zu reinigenden Fläche anliegende rotierende Mittel handeln kann, die von einem Motor angetrieben werden. Als Reinigungsmittel können beispielsweise aber auch Düsen vorgesehen sein, aus denen die Reinigungsflüssigkeit mit hohem Druck auf die zu reinigende Fläche gerichtet wird, oder ein Ultraschallimpulsgeber, der auf die den Reinigungskopf vollständig füllende Reinigungsflüssigkeit Ultraschallschwingungen überträgt, durch die Schmutzpartikel schnell und gründlich von der zu reinigenden Fläche abgelöst werden. Die Erfindung ist auf keine bestimmten Reinigungsmittel in dem Reinigungskopf beschränkt, sondern ganz allgemein auf beliebige Reinigungsköpfe anwendbar.The cleaning device does not have to be fully automatic , but it can also be a semi-automatic Act device in which e.g. the cleaning head by an operator on the surfaces to be cleaned is performed while the cleaning function of the cleaning head expires automatically. This means that the cleaning head the cleaning liquid is supplied by a pump and that the cleaning agents provided in the cleaning head work independently, these cleaning agents for example in order to rotate against the surface to be cleaned Can act means that are driven by a motor. However, nozzles can also be used as cleaning agents be provided, from which the cleaning liquid with high Pressure is applied to the surface to be cleaned, or an ultrasonic pulse generator, the on the cleaning head completely filling cleaning liquid transmits ultrasonic vibrations, through the dirt particles quickly and thoroughly from the surface to be cleaned. The invention is on no particular detergents restricted in the cleaning head, but in general on any cleaning heads applicable.
Die Reinigungsvorrichtung kann auch ein verhältnismäßig kleines Handgerät sein, bei der sich der Reinigungskopf an einem langen Rohr oder dergleichen befindet, mit dessen Hilfe der Reinigungskopf von einer Bedienungsperson beispielsweise über hochgelegene, ansonsten schlecht erreichbare Fensterflächen oder über das Dach eines Wintergartens geführt wird. The cleaning device can also be a relatively small one Be a handheld device with the cleaning head on a long Pipe or the like, with the help of the cleaning head by an operator, for example via high, otherwise difficult to reach window areas or is led over the roof of a winter garden.
Die zu reinigenden Flächen können grundsätzlich vertikal, schräg oder auch horizontal liegen, wobei die Reinigungsvorrichtung beispielsweise auch dazu einsetzbar ist, die Unterseite eines Glasdachs von Schmutz zu befreien.The surfaces to be cleaned can basically be vertical, sloping or also lie horizontally, with the cleaning device also for example can be used to remove dirt from the underside of a glass roof.
Aus der DE 195 45 517 A1 ist ein Dampfreinigungskopf bekannt, bei dem Dampf mehreren stirnseitig offenen Dampfdruckkammern zugeführt wird. Der Dampf löst den Schmtz von einer zu reinigenden Scheibe und strömt über Begrenzungsstege hinweg in Absaugbereich des Reinigungskopfes, von wo das Dampf/Wasser/Schmutzgemisch abgesaugt wird.From DE 195 45 517 A1 a steam cleaning head is known in which steam is supplied to several vapor pressure chambers open at the end. The steam dissolves the Schmtz from a pane to be cleaned and flows over boundary webs away in the suction area of the cleaning head, from where that Steam / water / dirt mixture is extracted.
Die DE-A-2 121 500 offenbart eine Reiniungsvorrichtung mit einem Reinigungskopf mit zwei Reinigungskammern, denen Reinigungsflüssigkeit zugeführt wird, die unter einem rahmenförmigen Gleitschuh hinweg in einen Unterdruckbereich gelangt, von wo sie abgesaugt wird.DE-A-2 121 500 discloses a cleaning device with a cleaning head with two cleaning chambers, to which cleaning liquid is supplied, which is under a frame-shaped slide shoe gets into a vacuum area, from where it is sucked off.
Die DE-A-18 17 917 offenbart einen Reinigungskopf mit mehreren Auflagefüßen, aus denen Flüssigkeit austritt, auf der der Reinigungskopf bei der Bewegung über die zu reinigende Fläche gleitet. Die dem Reinigungskopf zugeführte Reinigungsflüssigkeit tritt z.T. aus Austrittöffnungen am Boden einer sogenannten Glocke aus und gelangt außerdem durch Zweigleitungen zu den einzelnen Auflagefüßen, die hydrostatische Lageeinrichtungen bilden. Dies hat zur Folge, daß die Flüssigkeit aus den Lagerfüßen stets mit dem selben Betriebsdruck der Reinigungsflüssigkeit austritt.DE-A-18 17 917 discloses a cleaning head with several support feet, from which liquid emerges on which the cleaning head moves when moving over the surface to be cleaned slides. The fed to the cleaning head Cleaning liquid sometimes from outlet openings at the bottom of a so-called Bell off and also reaches the individual through branch lines Support feet that form hydrostatic position devices. This has the consequence that the liquid from the bearing feet always with the same operating pressure Cleaning liquid escapes.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Reinigungsvorrichtung der betrachteten Art anzugeben, bei der eine glatte Bewegung des Reinigungskopfes über die zu reinigende Fläche mit einem verhältnismäßig kleinen Kraftaufwand ermöglicht ist. The present invention has for its object a cleaning device of the type under consideration, in which a smooth movement of the Cleaning head over the surface to be cleaned with a relatively small Force is allowed.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention by the features of patent claim 1 solved.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are in the subclaims characterized.
Gemäß der vorliegenden Erfindung enthält der Reinigungskopf mehrere hydrostatische Lagereinrichtungen, aus denen Flüssigkeit austritt, auf der der Reinigungskopf bei der Bewegung über die zu reinigende Fläche gleitet. Die Flüssigkeit bildet dabei zwischen Stirnflächen des Reinigungskopfes und der zu reinigenden Fläche einen Flüssigkeitsfilm, der verhindert, daß der Reinigungskopf in direkten Kontakt mit der zu reinigenden Fläche gerät. Das Gleiten auf dem Flüssigkeitsfilm erfolgt praktisch reibungslos, so daß zum Führen des Reinigungskopfes über die zu reinigende Fläche nur ein sehr geringer Kraftaufwand erforderlich ist. Außerdem ist erfindungsgemäß vorgesehen, daß in der zu den hydrostatischen Lagern führenden Sammelleitung ein einstellbares Drosselventil angeordnet ist oder daß in den zu den hydrostatischen Lagern führenden Leitungen einstellbare Drosselventile angeordnet sind, mit dem bzw. denen der Druck der zugeführten Flüssigkeit veränderbar ist. Damit kann die Dicke des Flüssigkeitsfilms an den jeweiligen Anwendungsfall angepaßt werden. Es dürfte zweckmäßig sein, im Falle einer besonders rauhen oder unebenen Fläche die Dicke der Flüssigkeitsschicht entsprechend zu erhöhen.According to the present invention, the cleaning head contains several hydrostatic bearing devices from which liquid emerges on which the cleaning head glides over the surface to be cleaned when moving. The liquid forms between the end faces of the cleaning head and the one to be cleaned Surface a liquid film that prevents the cleaning head from being in direct Comes into contact with the surface to be cleaned. The sliding on the liquid film takes place practically smoothly, so that to guide the cleaning head over cleaning surface requires only very little effort. Besides, is According to the invention provided that leading to the hydrostatic bearings An adjustable throttle valve is arranged in the manifold or in that to the adjustable throttle valves arranged in hydrostatic bearings with which the pressure of the supplied liquid can be changed. So that the thickness of the liquid film can be adapted to the respective application be adjusted. It should be useful in the case of a particularly rough or uneven surface to increase the thickness of the liquid layer accordingly.
Durch die hydrostatischen Lagereinrichtungen ist außerdem erreicht, daß die zu reinigende Fläche vor Beschädigung durch den Reinigungskopf, beispielsweise vor einem Zerkratzen, geschützt ist und daß der Reinigungskopf wegen des Abstandes von der Fläche glatt über die Verunreinigungen auf der Fläche gleiten kann. The hydrostatic bearing devices also ensure that the cleaning surface before damage by the cleaning head, for example before a scratch, is protected and that the cleaning head because of the distance can slide smoothly from the surface over the contaminants on the surface.
Die hydrostatischen Lager sind bevorzugt mit dem Reinigungsflüssigkeitsbehälter verbunden, aus dem mittels einer Pumpe die Reinigungsflüssigkeit dem Reinigungskopf zugeführt wird. Hierbei handelt es sich um Wasser, dem geeignete Reinigungszusätze beigefügt sein können.The hydrostatic bearings are preferred with the cleaning liquid container connected, from which by means of a pump Cleaning liquid is fed to the cleaning head. in this connection it is water, the suitable cleaning additives can be attached.
Es kann aber auch vorgesehen sein, daß für die hydrostatischen Lager ein gesonderter Flüssigkeitsbehälter vorgesehen ist, so daß diese dann zweckmäßigerweise auch durch eine eigene Pumpeneinrichtung die Flüssigkeit zur Ausbildung des Flüssigkeitsfilm erhalten.But it can also be provided that for the hydrostatic Bearing a separate liquid container is provided, so that this then expediently also by its own pump device the liquid to form the liquid film receive.
In beiden Fällen wird die Reinigungsflüssigkeit der Reinigungskammer und die Flüssigkeit der hydrostatischen Lagereinrichtungen durch eine Unterdruckeinrichtung, beispielsweise einem Sauggebläse, in den Reinigungsflüssigkeitsbehälter abgesaugt, aus dem die Reinigungsflüssigkeit bevorzugt in einem geschlossenen Kreislauf wieder der Reinigungskammer zugeführt wird. Zuvor wird das Schmutzwasser durch eine an geeigneter Stelle vorgesehene Filtereinrichtung gereinigt.In both cases, the cleaning liquid becomes the cleaning chamber and the liquid of the hydrostatic bearing devices by a vacuum device, for example a Suction fan, sucked into the cleaning liquid container, from which the cleaning liquid is preferably in a closed Circuit is returned to the cleaning chamber. before the dirty water is provided by a suitable place Filter device cleaned.
Mit großem Vorteil wird dabei vorgeschlagen, daß die wenigstens eine Reinigungskammer und die hydrostatischen Lagereinrichtungen von einem umlaufenden Absaugkanal umgeben sind, der durch einen umlaufenden Steg von der Reinigungskammer getrennt sein kann. Bei dieser Ausgestaltung der Erfindung enthält der Reinigungskopf keinen Abstreifer in Form einer Dichtlippe oder dergleichen, sondern die gesamte Flüssigkeit wird in den Ringkanal eingesaugt, ohne daß Flüssigkeit über diesen hinaus nach außen austritt. Ohne Abstreifer ist der Reinigungskopf in jeder Richtung frei beweglich, wobei -wie oben erwähnt- das Gleiten auf einer dünnen Wasserschicht im Bereich der hydrostatischen Lagereinrichtungen glatt und praktisch ohne Reibungswiderstand vonstatten geht. Dies trifft auch auf den Fall zu, daß die zu reinigende Fläche nicht glatt, sondern rauh ist. It is proposed with great advantage that the least a cleaning chamber and the hydrostatic storage facilities are surrounded by a circumferential suction channel, which by a circumferential web can be separated from the cleaning chamber. In this embodiment of the invention, the cleaning head contains no wiper in the form of a sealing lip or the like, but all the liquid is in the ring channel sucked in without liquid beyond this to the outside exit. Without a scraper, the cleaning head is in every direction freely movable, whereby - as mentioned above - the sliding on a thin layer of water in the area of the hydrostatic storage facilities smooth and practically without frictional resistance goes. This also applies to the case that the cleaning surface is not smooth, but is rough.
Wenn -wie dies bevorzugt ist- den hydrostatischen Lagern die Flüssigkeit durch die Pumpe zugeführt wird, die auch die Reinigungskammer mit Flüssigkeit versorgt, ist vorzugsweise eine Einrichtung zur Reduzierung des Drucks vorgesehen, wobei der Wasserdruck an den hydrostatischen Lagern anders sein kann als der Druck des in die Reinigungskammer eingeführten Waschwassers.If - as is preferred - the liquid through the hydrostatic bearings Pump is supplied, which also supplies the cleaning chamber with liquid preferably a device for reducing the pressure is provided, the Water pressure at the hydrostatic bearings can be different than the pressure of the the washing chamber introduced washing water.
Die hydrostatischen Lager sind zweckmäßigerweise so ausgebildet, daß stirnseitige Wandabschnitte des Reinigungskopfes Öffnungen zum Austritt der Flüssigkeit aufweisen. Hierbei kann es sich um kreisrunde Löcher handeln, die sich zur Austrittsebene hin konisch oder beispielsweise in einer flachen Wannenform erweitern. Die Flüssigkeit fließt aus den Löchern bzw. Einsenkungen über die Stirnwandabschnitte in die Reinigungskammer und teilweise direkt in den umlaufenden Absaugkanal.The hydrostatic bearings are expediently designed so that the front Wall sections of the cleaning head openings for the liquid to exit exhibit. These can be circular holes that form the Extend the exit level conically or, for example, in a flat trough shape. The liquid flows out of the holes or depressions over the end wall sections into the cleaning chamber and partly directly into the rotating one Suction.
Zweckmäßigerweise sind entlang des Randes der Reinigungskammer mehrere voneinander beabstandete hydrostatische Lager angeordnet. Wenn der Reinigungskopf eine Rechteckform hat -worauf die Erfindung allerdings nicht beschränkt ist- sollten zumindest in den Eckbereichen der Reinigungskammer jeweils ein hydrostatisches Lager angeordnet sein, wobei auch zusätzliche hydrostatische Lager, beispielsweise in der Mitte der Längsseiten, vorgesehen sein können.Expediently there are several along the edge of the cleaning chamber spaced apart hydrostatic bearings. If the Cleaning head has a rectangular shape - but the invention does not is restricted - at least in the corner areas of the cleaning chamber one hydrostatic each Bearings may be arranged, with additional hydrostatic Bearings, for example in the middle of the long sides, can be provided.
Bei der erfindungsgemäßen Reinigungsvorrichtung wird fortlaufend Reinigungsflüssigkeit dem Reinigungskopf und den hydrostatischen Lagereinrichtungen zugeführt, die gleichzeitig bevorzugt aus einem außen umlaufenden Ringkanal wieder abgesaugt, aufbereitet und wieder zugeführt wird. Dabei zirkulieren verhältnismäßig große Wassermengen, die eine wirkungsvolle Reinigung von Glas-, Fassaden- und sonstigen Flächen ermöglichen, wobei dennoch ohne Anordnung umlaufender Dichtlippen gewährleistet ist, daß praktisch kein Wasser aus dem Bereich des Reinigungskopfs auf umliegende Flächen austritt und wobei der Reinigungskopf mit einem äußerst geringen Kraftaufwand über die Reinigungsfläche geführt werden kann.In the cleaning device according to the invention is ongoing Cleaning fluid to the cleaning head and hydrostatic Storage facilities fed, which preferably from at the same time suctioned off an externally circulating ring channel, processed and fed again. Circulate proportionately large amounts of water that effectively clean glass, Facades and other surfaces allow, but without Arrangement of circumferential sealing lips ensures that practical no water from the area of the cleaning head to surrounding areas Surfaces emerges and the cleaning head with a extremely little effort is passed over the cleaning surface can be.
