Abstract

An apparatus for cleaning surfaces has a cleaning head which is designed to bear against a surface being cleaned. The cleaning head includes a discharge nozzle which is connected with a source of flowable cleaning material and is arranged to discharge such material against the surface being cleaned. A pair of shields is disposed about the discharge nozzle. The cleaning head further includes a suction nozzle which is connected with a source of suction and serves to remove contaminated cleaning material from the surface being cleaned. A brush is disposed between the discharge nozzle and the suction nozzle and functions to scrub the surface after the cleaning material has been applied thereto. The discharge nozzle, suction nozzle and brush are surrounded by a tubular sleeve which inhibits the escape of contaminated cleaning material so that virtually all such material is recovered via the suction nozzle.

Description

Die vorliegende Erfindung betrifft ein Flächen- Reinigungsgerät mit mindestens einer Blasdüse, der ein Reinigungsmittel über eine Druckleitung zugeführt wird, mit mindestens einer Saugdüse, die mit einer Saugleitung verbunden ist, und mit mindestens einer Bürste, deren Borsten während der Arbeit auf die zu reinigende Fläche zu stehen kommen, wobei der Bereich der Blasdüse und der Bereich der Saugdüse gemeinsam derart mit einem Mantel ummantelt sind, dass das auf die zu reinigende Fläche zu liegen kommende gummielastische Ende des Mantels ganz offen ist.The present invention relates to a surface cleaning device with at least one blow nozzle, to which a cleaning agent is supplied via a pressure line, with at least one suction nozzle, which is connected to a suction line, and with at least one brush, the bristles of which are to be cleaned on the surface to be cleaned come to a standstill, the area of the blow nozzle and the area of the suction nozzle being encased together in such a way that the rubber-elastic end of the casing coming to lie on the surface to be cleaned is completely open.

Ein Flächen-Reinigungsgerät gemäß Oberbegriff des Patentanspruchs 1 ist aus der GB-A-845 991 bekannt. Flächenreinigungsgeräte der genannten Art sind für Wände, Decken, Glasflächen, Fassaden usw. nicht verwendbar, weil das Reinigungsmittel herunterläuft oder heruntertropft bevor es vom Gerät wieder aufgesaugt werden kann.A surface cleaning device according to the preamble of claim 1 is known from GB-A-845 991. Surface cleaning devices of the type mentioned cannot be used for walls, ceilings, glass surfaces, facades etc., because the cleaning agent runs down or drips down before the device can suck them up again.

Die Erfindung bezweckt ein Flächenreinigungsgerät der beschriebenen Art so zu verbessern, dass es praktisch für alle Arten von Flächen verwendbar ist.The invention aims to improve a surface cleaning device of the type described so that it can be used practically for all types of surfaces.

Diese Aufgabe wird durch das erfindungsgemässe Flächen-Reinigungsgerät gelöst, wie es im Patentanspruch 1 gekennzeichnet ist.This object is achieved by the surface cleaning device according to the invention, as characterized in claim 1.

Die auswechselbare Bürste ist zwischen der Blasdüse und der Saugdüse angeordnet, und zwischen der Saugdüse und dem schlauchartigen Mantel befindet sich eine Lamelle, die den weichen Mantel stützt.The interchangeable brush is located between the blow nozzle and the suction nozzle, and between the suction nozzle and the hose-like jacket there is a lamella which supports the soft jacket.

Nach Anspruch 2 ist diese Lamelle mit kammartigen Zähnen versehen, die dazu dienen beim Reinigen von Rolltreppen in die Rillen der Rolltreppenfläche einzudringen, was die Saugkraft der Saugdüse in den Rillen erhöht. Weiter ist das Flächenreinigungsgerät nach Anspruch 3 dadurch verbessert, dass seitlich der Blasdüse und mit Abstand davon zwei Schutzwände so V-förmig angeordnet sind, dass ihre freien Enden gegen die Enden der Bürste gerichtet sind.According to claim 2, this lamella is provided with comb-like teeth, which serve to penetrate the grooves of the escalator surface when cleaning escalators, which increases the suction force of the suction nozzle in the grooves. The surface cleaning device according to claim 3 is further improved in that two protective walls are arranged on the side of the blowing nozzle and at a distance from it so that their free ends are directed towards the ends of the brush.

Der Hauptvorteil dieses Gerätes ist, dass es trotz z. B. flüssigem Reinigungsmittel fast trocken arbeitet, weil das Reinigungsmittel nicht aus der Ummantelung fliessen kann, sondern sofort wieder aufgesaugt wird.The main advantage of this device is that despite z. B. liquid detergent works almost dry, because the detergent can not flow out of the jacket, but is immediately absorbed again.

Nachfolgend wird anhand der Zeichnung ein Ausführungsbeispiel des erfindungsgemässen Flächen-Reinigungsgerätes beschrieben.An exemplary embodiment of the surface cleaning device according to the invention is described below with reference to the drawing.

  • Figur 1 zeigt das Reinigungsgerät von unten gesehen,Figure 1 shows the cleaning device seen from below,
  • Figur 2 zeigt das Reinigungsgerät von der Seite mit Teilschnitt,Figure 2 shows the cleaning device from the side with partial section,
  • Figur 3 zeigt eine kammartige Lamelle, anwendbar beim Reinigen von Rolltreppen.Figure 3 shows a comb-like lamella, applicable when cleaning escalators.

Das Flächen-Reinigungsgerät ist mit mindestens einer Blasdüse 1 versehen, der das vorzugsweise flüssige Reinigungsmittel über eine Druckleitung 2 mit 4 atü Druck zugeführt wird. Mit einem Blasdüsen-Betätigungshebel 3 ist die Blasdüse 1 mittels Fingerdruck gegen den Druck einer Feder zu öffnen und durch Nachlassen des Fingerdrucks wieder zu schliessen. Eine quer zur Arbeitsrichtung des Gerätes angeordnete langgestreckte Saugdüse 4 ist mit einer Saugleitung 5 verbunden. Zwischen der Blasdüse 1 und der Saugdüse 4 befindet sich eine langgestreckte Bürste 6. Diese Bürste 6 ist je nach der zu tätigenden Arbeit entsprechend auswechselbar. Es gibt z. B. Bürsten mit Schweinsborsten zum Reinigen von Fenstern und Bürsten mit Messingborsten oder mit harten Polypropylenborsten für die Fassadenreinigung.The surface cleaning device is provided with at least one blowing nozzle 1, to which the preferably liquid cleaning agent is supplied via a pressure line 2 at 4 atm pressure. With a blow nozzle actuating lever 3, the blow nozzle 1 can be opened by finger pressure against the pressure of a spring and closed again by releasing the finger pressure. An elongate suction nozzle 4 arranged transversely to the working direction of the device is connected to a suction line 5. An elongated brush 6 is located between the blowing nozzle 1 and the suction nozzle 4. This brush 6 can be exchanged accordingly, depending on the work to be performed. There are e.g. B. Brushes with pig bristles for cleaning windows and brushes with brass bristles or with hard polypropylene bristles for facade cleaning.

Der Bereich der Blasdüse 1 und der Bereich der Saugdüse 4 sind gemeinsam derart mit einem schlauchstückartigen Mantel 7 ummantelt, dass das auf die zu reinigende Fläche zu liegen kommende Ende 8 des Mantels 7 ganz offen ist, während das gegenüberliegende Ende 9 mindestens teilweise offen ist. Der Mantel 7 besteht entweder ganz aus gummielastischem Material oder zumindest sein auf die zu reinigende Fläche zu liegen kommendes Ende 8. Als gummielastisches Material eignet sich besonders Naturgummi.The area of the blowing nozzle 1 and the area of the suction nozzle 4 are sheathed together in such a way with a tubular piece-like jacket 7 that the end 8 of the jacket 7 coming to lie on the surface to be cleaned is completely open, while the opposite end 9 is at least partially open. The jacket 7 either consists entirely of rubber-elastic material or at least its end 8 that lies on the surface to be cleaned. Natural rubber is particularly suitable as the rubber-elastic material.

Die Borsten der Bürste 6 sollen auf jeden Fall die zu reinigende Fläche berühren, das heisst sie sollen mit dem Ende 8 des Mantels 7 bündig sein oder aus dem Mantel-Ende 8 sogar etwas hervorstehen. Die Blasdüse 1 und die Saugdüse 4 hingegen bleiben wenigstens einen Zentimeter vom Ende 8 des Mantels 7 entfernt. Die Saugkraft der Saugdüse 4 entspricht 2 800 mm WS, d. h. sie entspricht 0,274 bar.The bristles of the brush 6 should in any case touch the surface to be cleaned, that is to say they should be flush with the end 8 of the jacket 7 or even protrude somewhat from the jacket end 8. The blowing nozzle 1 and the suction nozzle 4, however, remain at least one centimeter from the end 8 of the jacket 7. The suction force of the suction nozzle 4 corresponds to 2 800 mm WS, d. H. it corresponds to 0.274 bar.

Die Saugdüse 4 kann je nach Verwendungszweck des Reinigungsgeräts 3 cm bis 100 cm lang sein. Es können mindestens fünf auswechselbare Bürsten 6 mit verschiedenartigen Borsten vorhanden sein. Zwischen dem Mündungs-Aussenrand der Saugdüse 4 und der Innenwand des Mantels 7 befindet sich eine Lamelle 10, z. B. aus Neopren. Diese halbfeste bis feste Lamelle 10 hat den Zweck den weichen Mantel 7 zu stützen. Zum Reinigen von Rolltreppen kann diese Lamelle 10 kammartig ausgebildet sein. Die über den Mantel 7 vorstehenden Zähne 11 dienen dazu durch die Rillen der Rolltreppe gezogen zu werden. Dadurch dass die Zähne 11 in die Rillen der Rolltreppenfläche eindringen, wird der Ansaugbereich der Saugdüse 4 zur Stirnseite des Gerätes hin annähernd luftdicht abgeschlossen, was die Saugkraft der Saugdüse in den Rillen erhöht. Eine solche kammartige Lamelle ist in Fig. 3 dargestellt. Die kammartige Lamelle oder wenigstens ihre Zähne 11 bestehen zweckmässig aus gummielastischem Material. Selbstverständlich ist auch die kammartige Lamelle auswechselbar. Seitlich der Blasdüse 1 und mit Abstand davon sind zwei Schutzwände 12 so V-förmig angeordnet, dass ihre freien Enden annähernd gegen die Enden der Bürste 6 gerichtet sind. Die Bürste 6 könnte mittels eines Magnetmotors zum Vibrieren gebracht werden.Depending on the intended use of the cleaning device, the suction nozzle 4 can be 3 cm to 100 cm long. There may be at least five interchangeable brushes 6 with different types of bristles. Between the mouth of the suction nozzle 4 and the inner wall of the jacket 7 there is a lamella 10, for. B. made of neoprene. This semi-solid to solid lamella 10 has the purpose of supporting the soft jacket 7. For cleaning escalators, this slat 10 can be comb-shaped. The teeth 11 protruding over the jacket 7 serve to be pulled through the grooves of the escalator. Characterized in that the teeth 11 penetrate into the grooves of the escalator surface, the suction area of the suction nozzle 4 is almost airtight towards the front of the device, which increases the suction force of the suction nozzle in the grooves. Such a comb-like lamella is shown in FIG. 3. The comb-like lamella or at least its teeth 11 suitably consist of rubber-elastic material. Of course, the comb-like lamella can also be replaced. To the side of the blowing nozzle 1 and at a distance from it, two protective walls 12 are arranged in a V-shape so that their free ends are approximately directed towards the ends of the brush 6. The brush 6 could be made to vibrate by means of a magnetic motor.

Im Bereich der Lamelle 10 kann der Mantel 7 verstärkt sein, beispielsweise durch Überlappung. Bei Gebäuden bis zu 10 Metern Höhe ist mit dem beschriebenen Flächen-Reinigungsgerät zur Fassadenreinigung kein Gerüst mehr nötig, eine den Sicherheitsvorschriften entsprechende Leiter genügt.In the area of the lamella 10, the jacket 7 can be reinforced, for example by overlapping. In buildings up to 10 meters high, the described surface cleaning device for facade cleaning means that scaffolding is no longer necessary; a ladder that complies with safety regulations is sufficient.
