Definitions
- the present invention relates to a surface cleaning device with at least one blowing nozzle to which the cleaning agent is supplied via a pressure line and with at least one suction nozzle which is connected to a suction line.
- the invention aims to provide a surface cleaning device that can be used practically for all types of surfaces.
- the cleaning device according to the invention is characterized by the features of the characterizing part of patent claim 1.
- the main advantage of this device is that despite e.g. liquid detergent works almost dry because the detergent cannot flow out of the casing but is immediately absorbed again.
- 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.
- a blow nozzle actuating lever 3 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.
- brushes with pig bristles for cleaning windows and brushes with brass bristles or with hard polypropylene bristles for facade cleaning There are, for example, brushes with pig bristles for cleaning windows and brushes with brass bristles or with hard polypropylene bristles for facade cleaning.
- 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 lying on the surface to be cleaned. Natural rubber is particularly suitable as the rubber-elastic material.
- 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 remain at least one centimeter from the end 8 of the jacket 7.
- the suction power of the suction nozzle 4 corresponds to a water column of 2.8 m, ie it corresponds to 2800 mm water column.
- 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.
- lamella 10 for example made of neoprene, between the mouth of the suction nozzle 4 and the inner wall of the jacket 7.
- This semi-solid to solid lamella 10 has the purpose of supporting the soft jacket 7.
- 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 the grooves of the escalator surface, the suction area of the suction nozzle 4 to the front of the device is almost airtight, which increases the suction power of the suction nozzle in the grooves and enables proper cleaning.
- FIG. 3 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. It goes without saying that interchangeable comb-like lamella.
- 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.
- the jacket 7 can be reinforced, for example by overlapping.
- the described surface cleaning device for facade cleaning means that scaffolding is no longer necessary; a ladder that complies with safety regulations is sufficient.

Abstract
Description
- Die vorliegende Erfindung betrifft ein Flächen-Reinigungsgerät mit mindestens einer Blasdüse der das Reinigungsmittel über eine Druckleitung zugeführt wird und mit mindestens einer Saugdüse die mit einer Saugleitung verbunden ist.
- Es sind zwar Flächen-Reinigungsgeräte bekannt, die sich aber hauptsächlich nur für Teppiche und Fussböden eignen. Für Wände, Decken, Glasflächen, Fassaden usw. sind die bekannten Geräte nicht verwendbar, weil das Reinigungsmittel herunterläuft oder heruntertropft bevor es vom Gerät wieder aufgesaugt werden kann.
- Die Erfindung bezweckt ein Flächen-Reinigungsgerät zu schaffen, das praktisch für alle Arten von Flächen verwendbar ist.
- Gekennzeichnet ist das erfindungsgemässe Reinigungsgerät durch die Merkmale des kennzeichnenden Teils vom Patentanspruch 1.
- 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.
- Nachfolgend wird anhand der Zeichnung ein Ausführungsbeispiel des erfindungsgemässen Flächen-Reinigungsgerätes beschrieben.
- Figur 1 zeigt das Reinigungsgerät von unten gesehen,
- Figur 2 zeigt das Reinigungsgerät von der Seite mit Teilschnitt,
- Figur 3 zeigt eine kammartige Lamelle, anwendbar beim Reinigen von Rolltreppen.
- 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. 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.
- 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 einer Wassersäule von 2,8 m, d.h. sie entspricht 2800 mm WS. 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 und ein richtiges Reinigen erst ermöglicht. 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.
- 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.
