Description

Die Erfindung betrifft eine Vorrichtung zur Reinigung von glatten Oberflächen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for cleaning smooth surfaces according to the preamble of patent claim 1.

STAND DER TECHNIKSTATE OF THE ART

Das Reinigen von glatten Flächen wie Fenstern und Wänden im Innenraum mit einer Arbeitshöhe oberhalb von etwa 2 Metern erfolgt heutzutage meistens von einer Person auf einer Leiter, einem Gerüst oder einer Hebebühne mit einem Eimer Wasser, einem Schwamm und einem Wischer. Es wurde auch schon in DE-U-80 19 169 vorgeschlagen, eine Halterung mit einem Schwamm und einem Gummistreifen am Eingang einer an sich bekannten Saugdüse eines Sprüh-Extraktionsgerätes zu befestigen, damit das Sprüh-Extraktionsgerät auch zum Reinigen von Fensterscheiben verwendet werden kann. Auch wenn ein TeleskopRohr für die bekannte Saugdüse eingesetzt werden kann, ist bei der gegebenen Anordnung des bekannten Sprüh-Extraktionsgerätes für Teppichböden eine Reinigung von Fenstern in grosser Höhe nicht möglich. Ausserdem lassen sich Fenster auch kaum schlierenfrei mit der bekannten Saugdüse und Aufsatz reinigen. Die Halterung aus DE-U-80 19 169 ist denn auch nicht auf dem Markt erhältlich.The cleaning of smooth surfaces such as windows and walls in the interior with a working height above about 2 meters is nowadays usually done by a person on a ladder, a scaffold or a lift with a bucket of water, a sponge and a wiper. It was already in DE-U-80 19 169 proposed to attach a holder with a sponge and a rubber strip at the entrance of a known suction nozzle of a spray extraction device, so that the spray extraction device can also be used for cleaning window panes. Even if a telescopic tube can be used for the known suction nozzle, in the given arrangement of the known spray extraction device for carpets, a cleaning of windows in high altitude is not possible. In addition, windows can hardly be cleaned streak-free with the known suction nozzle and attachment. The holder off DE-U-80 19 169 is not available on the market.

In US-A-2004/0221420 ist ein Gerät für die Reinigung von verschmutzten Oberflächen eines Flugzeuges bekannt, welches am Ende eines Saugrohres einen Schrubber und einen Absauger aufweist. Der Absauger besteht aus einem ersten gezackten Abstreifer, einer Saugöffnung und einem zweiten Abstreifer und liegt dem Schrubber diametral gegenüber. In der Einleitung dieser Schrift wird betont, dass die herkömmlichen Reinigungsgeräte für Fenster oder Böden nicht geeignet sind für die Reinigung der durch Schrauben und Nieten unebenen Oberflächen von Flugzeugen. Demzufolge ist dieses Gerät nicht für die Reinigung von glatten Oberflächen wie Fenstern oder Wänden vorgesehen und auch nicht dazu geeignet.In US-A-2004/0221420 a device for the cleaning of soiled surfaces of an aircraft is known, which has at the end of a suction pipe a scrubber and an aspirator. The aspirator consists of a first serrated scraper, a suction port and a second scraper and is diametrically opposed to the scrubber. In the introduction of this document, it is emphasized that the conventional cleaning devices for windows or floors are not suitable for cleaning the uneven surfaces of aircraft due to screwing and riveting. Consequently, this device is not intended for the cleaning of smooth surfaces such as windows or walls and also not suitable.

AUFGABE DER ERFINDUNGOBJECT OF THE INVENTION

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung zur Reinigung von glatten Oberflächen, insbesondere für Fenster, anzugeben, die einfach handhabbar ist und die Reinigung von glatten Oberflächen in grosser Höhe ohne weitere Hilfsmittel ermöglicht.The present invention is an object of the invention to provide a device for cleaning smooth surfaces, especially for windows, which is easy to handle and allows the cleaning of smooth surfaces at high altitude without further aids.

GEGENSTAND DER ERFINDUNGSCOPE OF THE INVENTION

Diese Aufgabe wird durch eine Reinigungsvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a cleaning device having the features of patent claim 1.

Die erfindungsgemässe Reinigungsvorrichtung hat den grossen Vorteil, dass die Benetzung und die Trocknung der Fensterscheiben in zwei aufeinanderfolgenden Arbeitsabläufen vorgenommen werden kann, so dass eine einwandfreie und schlierenfreie Reinigung erreicht wird.The inventive cleaning device has the great advantage that the wetting and drying of the windows can be made in two successive operations, so that a perfect and streak-free cleaning is achieved.

BESCHREIBUNG EINES AUSFÜHRUNGSBEISPIELES DER ERFINDUNGDESCRIPTION OF AN EMBODIMENT OF THE INVENTION

Fig. 1
a cleaning device in side view,
Fig. 2

the cleaning device of FIG. 2 in a larger view.

In Figur 1 ist eine Reinigungsvorrichtung 1 gezeigt, die einen Kopfteil 2 mit einem Saugteil 3 und einem Reinigungsteil 4 aufweist. Der Saugteil 3 besteht aus einem gewinkelten Rohrstück 5 und einem flachen Saugkopf 6, welcher Aussparungen bzw. Saugöffnungen 7 und einen als Gummilippe ausgebildeten Abstreifer 8 aufweist. Der Reinigungsteil 4 besteht aus einer Sprühdüse 10 mit einem Druckregler 11 und einem an einem Stab 12 befestigten Waschkopf 13, welcher einen länglichen Schwamm 14 besitzt. Der Stab 12 ist mit einem Befestigungsteil 15 versehen, welcher mittels einer Schraube 16 an einem Ausleger 17 des Kopfteiles 2 befestigt ist. Ferner ist die Sprühdüse 10 mit einer Verbindungsstange 18 an dem Befestigungsteil 15 angebracht. Somit kann der Winkel α zwischen dem Saugteil 3 und dem Reinigungsteil 4 eingestellt werden, welcher in der Regel etwa 90° ist. Am Kopfteil 2 ist ein Rohr 20 angeschlossen, welches am unteren Ende über einen Saugschlauch 21 mit einem Wassersauger 22 (siehe Figur 2) verbunden ist. Ferner ist an der Sprühdüse 10 eine Wasserzufuhrleitung 25 angeschlossen, welche an einem handelsüblichen Druckbehälter 27 oder mit einer Schlauchrolle an einem Wasserhahn im Haus angeschlossen ist. Die Wasserzufuhr in der Wasserzufuhrleitung 25 wird durch ein drehbares Ventil 26 geregelt, d.h. sie kann geöffnet oder geschlossen werden. Das Saugrohr 20 besteht aus einem geeigneten Kunststoff wie einem Faser-Kunststoff-Verbundwerkstoff, insbesondere einem kohlefaserverstärkten Verbundwerkstoff (CFK), oder aus einem Metallmatrix-Verbundwerkstoff (MMC) mit Aluminium, Magnesium, Kupfer oder dergleichen. Das Saugrohr 20 kann als Teleskoprohr ausgebildet sein oder auch aus mehreren zusammengesteckten Rohren bestehen, um die Reinigungsvorrichtung 1 auf die richtige Höhe anzupassen. Das Saugrohr 20 hat einen Innendurchmesser von 38 mm und eine Wandstärke von 2 mm. Durch die leichte Bauweise hat das Rohr 20 die nötige mechanische Stabilität und kann trotzdem von einer Bedienungsperson mit einem weiten Abstand zu einer Reinigungsfläche wie einem Fenster mit dem nötigen Druck gehandhabt werden.In FIG. 1 a cleaning device 1 is shown, which has a head part 2 with a suction part 3 and a cleaning part 4. The suction part 3 consists of an angled pipe section 5 and a flat suction head 6, which recesses or suction openings 7 and designed as a rubber lip scraper 8 has. The cleaning part 4 consists of a spray nozzle 10 with a pressure regulator 11 and attached to a rod 12 washing head 13, which has an elongated sponge 14. The rod 12 is provided with a fastening part 15, which is fastened by means of a screw 16 to a boom 17 of the head part 2. Further, the spray nozzle 10 is attached to the attachment part 15 with a connecting rod 18. Thus, the angle α between the suction part 3 and the cleaning part 4 can be adjusted, which is usually about 90 °. At the head part 2, a tube 20 is connected, which at the lower end via a suction hose 21 with a water suction device 22 (see FIG. 2 ) connected is. Further, a water supply line 25 is connected to the spray nozzle 10, which is connected to a commercial pressure vessel 27 or with a hose reel to a faucet in the house. The water supply in the water supply line 25 is controlled by a rotatable valve 26, that is, it can be opened or closed. The suction tube 20 is made of a suitable plastic such as a fiber-plastic composite material, in particular a carbon fiber reinforced composite (CFRP), or of a metal matrix composite material (MMC) with aluminum, magnesium, copper or the like. The suction tube 20 may be formed as a telescopic tube or consist of several mated tubes to adjust the cleaning device 1 to the correct height. The suction tube 20 has an inner diameter of 38 mm and a wall thickness of 2 mm. Due to the lightweight construction, the tube 20 has the necessary mechanical stability and can still be handled by an operator with a far distance to a cleaning surface such as a window with the necessary pressure.

Die Reinigung der glatten Fläche geschieht nun in zwei Schritten:

  1. 1. Die zu reinigende Fläche wird mit der Sprühdüse 10 leicht benetzt, indem das Wasserventil 26 geöffnet und ein feiner Sprühnebel auf die Fläche verteilt wird. Durch eine Auf- und Abbewegung des Waschkopfes 13 wird der Schmutz auf der Fläche gelöst.
  2. 2. Sodann wird das Wasserventil 26 geschlossen und das Rohr 20 um 180° um die Längsrichtung gedreht, so dass der Saugkopf 6 an der zu reinigenden Fläche anliegt. Mit diesem Saugkopf 6 wird nun der Schmutzwasserfilm in einer durchgehenden Abwärtsbewegung abgesaugt und gleichzeitig durch den Abstreifer 8 vollständig abgezogen bzw. abgetrocknet. Das Schmutzwasser vom Abstreifer 8 wird gleichzeitig durch den Saugkopf 6 abgesaugt, so dass kein Restwasser mehr am Fensterrahmen verbleibt.
Cleaning the smooth surface is now done in two steps:
  1. 1. The surface to be cleaned is slightly wetted with the spray nozzle 10 by the water valve 26 is opened and a fine spray is distributed to the surface. By an up and down movement of the washing head 13, the dirt is dissolved on the surface.
  2. 2. Then the water valve 26 is closed and the tube 20 is rotated by 180 ° about the longitudinal direction, so that the suction head 6 on the surface to be cleaned is applied. With this suction head 6, the dirty water film is now sucked off in a continuous downward movement and at the same time completely removed or dried off by the scraper 8. The dirty water from the scraper 8 is simultaneously sucked through the suction head 6, so that no residual water remains on the window frame.

Mit der Reinigungsvorrichtung 1 kann man nun in grossen Höhen mit sehr wenig Wasser eine grosse glatte Fläche reinigen. Lediglich feine Tröpfchen vom Sprühnebel können auf den Boden gelangen, die jedoch mit einem Tuch aufgenommen werden können. Die leichte Bauweise der Reinigungsvorrichtung 1 mit dem Saugrohr 20 ermöglicht ein Arbeiten bis hoch hinauf, so dass problemlos Fenster von grossen Hallen gereinigt werden können.With the cleaning device 1 you can now clean at high altitudes with very little water a large smooth surface. Only fine droplets from the spray can reach the floor, but they can be picked up with a cloth. The lightweight design of the cleaning device 1 with the suction tube 20 allows working up high, so that windows can be cleaned easily from large halls.
