Abstract

A smooth-running floor cleaning device based on the spray extraction method, with a spray nozzle (2) for dispensing a cleaning liquid on a floor and a suction nozzle (6) for aspirating said cleaning liquid, can also be used as a device for mechanically treating said floor. This can be achieved in a technically simple manner and without practically adding any weight to said device by means of a row of bristles (13), pivoting around an axis parallel to the suction opening (8) of the suction nozzle (6), which extends along the whole width of said nozzle.

Description

Die Erfindung betrifft ein Fußbodenreinigungsgerät mit einem eine Sprühdüse und daran angrenzend eine Saugdüse aufweisenden Bodendü­senkopf, wobei aus der Sprühdüse eine Reinigungsflüssigkeit in einem Bereich mit etwa der Arbeitsbreite der Saugöffnung der Saugdüse aus­zubringen und mit der Saugdüse wieder aufzunehmen ist.The invention relates to a floor cleaning device with a floor nozzle head having a spray nozzle and adjoining it a suction nozzle, wherein a cleaning liquid is to be applied from the spray nozzle in an area with approximately the working width of the suction opening of the suction nozzle and is to be taken up again with the suction nozzle.

Mit derartigen Sprühextraktionsgeräten wird eine Reinigungsflüs­sigkeit über eine Sprühdüse unmittelbar vor die Saugdüse (beim Schieben des Geräts) auf den Boden gesprüht. Zugleich wird der mit einem Handrohr, Druck- und Saugschlauch verbundene Bodendüsenkopf in geraden Bahnen bei ständigem Saugen über die zu reinigende Fläche gezogen oder geschoben. Die auf den Boden gelangende Reini­gungsflüssigkeit löst den Schmutz an und wird zusammen mit dem Schmutz über die Saugdüse und einen Handrohrsaugschlauch in einen Schmutzflottenbehälter abgezogen. Die Einwirkzeit der Reinigungs­flotte ist in der Regel beim einfachen Abfahren der zu reinigenden Fläche gering, die Zeit kann jedoch durch separates Einsprühen und späteres Absaugen gesteigert werden.With such spray extraction devices, a cleaning liquid is sprayed onto the floor via a spray nozzle directly in front of the suction nozzle (when pushing the device). At the same time, the floor nozzle head, which is connected to a hand pipe, pressure hose and suction hose, is pulled or pushed in straight lines with constant suction over the surface to be cleaned. The cleaning liquid that gets onto the floor dissolves the dirt and is drawn off together with the dirt via the suction nozzle and a hand tube suction hose into a dirty liquor container. The action of the cleaning liquor is usually short by simply moving the surface to be cleaned, but the time can be increased by spraying and then vacuuming off separately.

Hartnäckige Verschmutzungen in textilen Belägen können oft nicht allein durch Einsprühen und Absaugen der Reinigungsflüssigkeit sondern nur durch mechanische Unterstützung entfernt werden. Ent­sprechende Scheuer- oder Reibgeräte werden am Bodendüsenkopf nicht angebracht, weil dieser Kopf zum Erleichtern der Arbeit leicht glei­ten soll . Die Gleitflächen üblicher Bodendüsenköpfe sind daher in der Regel aus festem, glattem, das Gleiten unterstützendem Material, wie z. B. Metall oder Kunststoff, gefertigt. Da es schwierig ist, mit diesem relativ glattem Bodendüsenkopf durch Hin- und Herbewegung die zur Steigerung des Reinigungseffekts erforderliche Reibung zu erzeugen, werden in der Praxis sogenannte Vorsatz- oder Zusatzgeräte mit elektromotorisch betriebenen Bürstwalzen verwendet. Diese Vor- bzw. Zusatzgeräte wiegen konstruktionsbedingt meist mehrer Kilo­gramm, sie sind also - zumindest aus anwendungstechnischer Sicht - als schwer zu bezeichnen. Sie sind unhandlich, haben geringe Rand­gängigkeit und eignen sich eigentlich nur für große, nicht über­stellte Flächen. Außerdem ist der Anschaffungsaufwand relativ hoch.Stubborn soiling in textile coverings can often not be achieved simply by spraying and vacuuming the cleaning liquid but can only be removed by mechanical support. Corresponding scouring or rubbing devices are not attached to the floor nozzle head because this head should slide easily to make work easier. The sliding surfaces of conventional floor nozzle heads are therefore usually made of solid, smooth, sliding material, such as. B. metal or plastic. Since it is difficult to produce the friction required to increase the cleaning effect with this relatively smooth floor nozzle head, so-called attachments or auxiliary devices with electromotive brush rollers are used in practice. Due to their design, these pre- and additional devices usually weigh several kilograms, so they are - at least from an application technology point of view - difficult to describe. They are unwieldy, have little access to the edges and are actually only suitable for large, uncovered areas. In addition, the purchase cost is relatively high.

Der Erfindung liegt die Aufgabe zugrunde, einen üblichen, einfachen Bodendüsenkopf ohne aufwendige Vor- oder Zusatzgeräte so auszuge­stalten, daß er die für die Erleichterung der Arbeit erforderliche Leichtgängigkeit behält und trotzdem die Möglichkeit bietet, ledig­lich durch Hin- und Herbewegungen, das heißt durch Vorschieben und Zurückziehen, die zum Steigern des Reinigungseffektes erforderliche mechanische Bodenbehandlung zu liefern. Die erfindungsgemäße Lösung ist für ein Fußbodenreinigungsgerät eingangs genannter Art mit einem eine Sprühdüse und unmittelbar daran angrenzend eine Saugöffnung aufweisenden Bodendüsenkopf gekennzeichnet durch einen schwenkbar um eine parallel zur Saugöffnung verlaufende Achse, unmittelbar an der Saugöffnung gelagerten, sich über die ganze Breite des Bodendüsen­kopfes erstreckenden Borststreifen und einen beim Ziehen des Bodendüsen­kopfes den Schwenkwinkel des Borststreifens beschränkenden An­schlag.The invention has for its object to design a conventional, simple floor nozzle head without complex preliminary or additional devices so that it retains the smoothness required for facilitating the work and still offers the possibility of merely moving back and forth, that is to say by advancing and Withdrawal to provide the mechanical floor treatment required to enhance the cleaning effect. The solution according to the invention is characterized for a floor cleaning device of the type mentioned at the outset with a floor nozzle head having a spray nozzle and immediately adjacent to it with a suction opening, by a bristle strip which is pivotable about an axis running parallel to the suction opening and is mounted directly on the suction opening and extends over the entire width of the floor nozzle head a stop limiting the swivel angle of the bristle strip when pulling the floor nozzle head.

Erfindungsgemäß wird also am Bodendüsenkopf ein Bürst- oder Borst­streifen derart beweglich befestigt, daß er bei den erfahrungsgemäß großen Kräften, die zum Schieben des Geräts erforderlich sind, nach hinten umkippt und den normalen Gleitwiderstand des Bodendüsenkopfes nicht nennenswert erhöht. Bei ziehender Bewegung des Bodendüsen­kopfes über den Boden soll sich der erfindungsgemäße Borststreifen jedoch aufrichten und durch einen Anschlag in einer für die mecha­nische Zusatzbehandlung wirksamen Stellung gehalten werden. Da die erfordlichen Kräfte zum Ziehen einer Saugdüse ergonomisch besser zu kompensieren sind als die Kräfte zum Schieben der Düse und durch den erfindungsgemäßen Borststreifen wesentliche Zusatzkräfte nur beim Ziehen auftreten, können sowohl die beim Schieben als auch die beim Ziehen durch die Bürstmechanik begründeten Widerstände ohne nennenswert über das bisherige Maß hinausgehende körperliche Belastung des Arbeitspersonals überwunden werden.According to the invention, a brush or bristle strip is thus movably attached to the floor nozzle head in such a way that it tilts backwards under the experience of the large forces required for pushing the device and does not significantly increase the normal sliding resistance of the floor nozzle head. When the floor nozzle head moves across the floor, however, the bristle strip according to the invention should stand up and be held in a position effective for the additional mechanical treatment by a stop. Since the required forces for pulling a suction nozzle can be better compensated ergonomically than the forces for pushing the nozzle and due to the bristle strip according to the invention, significant additional forces only occur when pulling, both the resistances established during pushing and pulling due to the brush mechanism can be significantly reduced the physical strain on the workforce going beyond the previous level can be overcome.

Gemäß weiterer Erfindung wird dem Borststreifen ein dessen Schwenk­bewegung auch beim Schieben des Bodendüsenkopfes beschränkender An­schlag zugeordnet. Dieser Anschalg soll so liegen, daß der Borst­streifen in der inaktiven Stellung nur so weit wegkippt, daß er beim Übergang zum Ziehen selbsttätig in die für die mechanische Reinigung wirksam aufgerichtete Stellung zurückkippt. Der Borststreifen wird also beim Schieben in einer inaktiven Stellung so gehalten, daß er bei Richtungsänderung, das heißt, beim Übergang vom Schieben zum Ziehen des Bodendüsenkopfes sofort von selbst in die aktive Bürst-Reinigungs-Stellung umschwenkt. Während demgemäß die Spitzen der Borsten des Borststreifens in der inaktiven Stellung, also beim Schieben des Bodendüsenkopfes, fast bodenfrei weggeklappt sein sol­len, werden sie bei ziehender Bewegung des Bodendüsenkopfes bis zu ihrem Anschlag so weit nach vorne geklappt, daß sie in diesem aufge­richteten Zustand um einige Millimeter über eine die Saugöffnung der Saugdüse begrenzende bzw. definierende Gleitschiene hinausragen.According to a further invention, the bristle strip is assigned a stop restricting its swiveling movement even when the floor nozzle head is pushed. This attachment should be such that the bristle strip in the inactive position only tilts so far away that it automatically tilts back into the position effectively set up for mechanical cleaning during the transition to pulling. The bristle strip is thus held in an inactive position when pushed so that when the direction changes, that is, during the transition from pushing to pulling the floor nozzle head, it swings automatically into the active brush cleaning position. Accordingly, while the tips of the bristles of the bristle strip in the inactive position, i.e. when pushing the floor nozzle head, are to be folded away almost without a floor, when the floor nozzle head is pulled, they are folded forward as far as possible until they stop, so that in this erect state they are raised by a few Extend millimeters beyond a slide rail that defines or defines the suction opening of the suction nozzle.

Vorzugsweise weist der Borststreifen eine Tragschiene auf, die an ihren Längsenden in Seitenwänden des Bodendüsenkopfes schwenkbar ge­lagert ist. Zum Befestigen des Borststreifens sind dann lediglich in den ungefähr im rechten Winkel zur Längsachse der Tragschiene ste­henden Seitenwänden anzubringende Lagerlöcher erforderlich. Vorteil­haft wird als Tragschiene eine einen U-förmigen Querschnitt aufwei­sende Schiene aus Metall oder Kunststoff mit zwischen den U-Schen­keln kraft- oder stoffschlüssig befestigten Borsten aus Naturfaser oder Kunststoff vorgesehen. Eine solche U-förmige Tragschiene ge­währleistet trotz geringen Herstellungsaufwands, eine für den Be­trieb des Fußbodenreinigungsgeräts ausreichende Stabilität.The bristle strip preferably has a mounting rail which is pivotally mounted at its longitudinal ends in side walls of the floor nozzle head. To attach the bristle strip, it is then only necessary to make bearing holes in the side walls which are approximately at right angles to the longitudinal axis of the mounting rail. A rail made of metal or plastic with a U-shaped cross-section with bristles made of natural fiber or plastic attached to the U-legs in a force-fitting or material-locking manner is advantageously provided as the mounting rail. Such a U-shaped mounting rail ensures sufficient stability for the operation of the floor cleaning device, despite the low manufacturing effort.

Die Montage des Borststreifens insgesamt wird erleichtert, wenn der Tragschiene in den Seitenwänden Aufnahmelöcher mit einer den größten Schienendurchmesser übersteigenden lichten Weite zugeordnet werden. Wenn sich die Borsten beim Passieren der Löcher umlegen und sich dann wieder aufrichten, kann unter diesen Umständen der Borststreifen zum Arretieren einfach durch die Aufnahmelöcher hin­durchgeschoben werden. Die Schwenkbewegung des Borststreifens wird besonders leichtgängig, und außerdem wird ein ungewolltes Heraus­rutschen des Borststreifens aus seiner Lagerung vermieden, wenn der Borststreifen in den für die Lagerung in den Aufnahmelöchern vorge­sehenen Längsabschnitten je eine Borstenlücke aufweist. Wenn dann an den durch die Seitenwände durchstoßenden Längsenden des Borststrei­fens kleine Borstenbüschel hervorragen, wird ein ungewolltes Heraus­rutschen des Borststreifens praktisch ausgeschlossen. Natürlich könnte der Borststreifen auch durch aufgesetzte Gewinde und Schrauben oder dergleichen gesichert werden. Ein einfaches Ein­stecken und eine selbsttätige Sicherung, beispielsweise durch die Borstenlücken, sind aber wesentlich praxisnäher.The assembly of the bristle strip as a whole is facilitated if the mounting rail in the side walls is assigned receiving holes with a clear width exceeding the largest rail diameter. Under these circumstances, if the bristles fold over when they pass through the holes and then straighten up again, the bristle strip can simply be pushed through the receiving holes for locking. The pivoting movement of the bristle strip becomes particularly smooth and, in addition, an undesired slipping out of the bristle strip from its storage is avoided if the bristle strip has a bristle gap in the longitudinal sections provided for storage in the receiving holes. If small tufts of bristles then protrude from the longitudinal ends of the bristle strip penetrating through the side walls, an unwanted slipping out of the bristle strip is practically excluded. Of course, the bristle strip could also be secured by threads and screws or the like. Simple plugging in and automatic securing, for example through the bristle gaps, are much more practical.

Die die aktive und die inaktive Schwenkstellung des Borststreifens begrenzenden Anschläge werden gemäß weiterer Erfindung ohne nennens­werten zusätzlichen Aufwand geschaffen, wenn die Aufnahmelöcher der Seitenwände als Segmentaussparungen etwa nach Art eines in einen kleineren Vollkreis mündenden Viertel-Kreis-Ausschnitts geformt und wenn die Kreisausschnittradien der Segmentaussparungen als Anschläge zum Begrenzen der Schwenkbewegung des Borstenstreifens ausgebildet und ausgerichtet werden.Für die Lagerung des Rückens der Tragschiene mit gegebenenfalls U-förmigem Querschnitt wird zweckmäßig ein klei­nerer Vollkreis an der Spitze des Viertel-Kreisauschnitts vorgese­hen. Das Aufnahmeloch hat dann in etwa die Form eines herkömmlichen Schlüssellochs mit übermäßig aufgespreiztem Bartschlitz. Durch Aus­bildung der Aufnahmelöcher als Segmentaussparungen der angegebenen Art und durch eine angepaßte Form der Tragschiene werden zugleich die Anschläge für das Feststellen des Borststreifens in der aktiven Stellung als auch für das Begrenzen der Wegkipp-Stellung (beim Schieben) geschaffen.The active and inactive swivel position of the bristle strip Limiting stops are created according to a further invention without any significant additional effort if the receiving holes of the side walls are shaped as segment recesses approximately in the manner of a quarter-circle cutout opening into a smaller full circle and if the circular cutout radii of the segment recesses are designed as stops for limiting the pivoting movement of the bristle strip and For the storage of the back of the mounting rail with a possibly U-shaped cross-section, a smaller full circle is expediently provided at the top of the quarter-circle cut-out. The receiving hole then has approximately the shape of a conventional keyhole with an excessively spread beard slot. By designing the receiving holes as segment recesses of the specified type and by adapting the shape of the mounting rail, the stops for locking the bristle strip in the active position and for limiting the tilting position (when pushing) are created at the same time.

Das Fußbodenreinigungsgerät nach Fig. 1 und 2 besitzt einen insge­samt nicht 1 bezeichneten Bodendüsenkopf mit einer Sprühdüse 2 und dieser zugeordneter Sprühkammer 3 mit schirmförmiger Abdeckung 4 und Seitenwänden 5. Zu dem Bodendüsenkopf 1 gehört außerdem eine Saugdü­se 6 mit einer durch eine den Gleitwiderstand des Geräts herabset­zenden Gleitschiene 7 aufweisenden Saugöffnung 8. Die Sprühdüse 2 wird über einen Schlauch 9 mit daran angeschlossener Pumpe mit Rei­nigungsflüssigkeit versorgt. Die Reinigungsflüssigkeit wir aus der Sprühdüse 2 - verteilt in etwa auf die Arbeitsbreite der Saugöffnung 8 - auf den zu reinigenden Boden gesprüht. Im allgemeinen wird zu­gleich mit dem Sprühen vorher aufgebrachte Reinigungsflüssigkeit zu­sammen mit bereits angelöstem Schmutz über die Saugdüse 6 in Pfeil­richtung 10 in einen Schmutzflottenbehälter abgezogen.1 and 2 has a floor nozzle head, not designated as a whole, with a spray nozzle 2 and this associated spray chamber 3 with an umbrella-shaped cover 4 and side walls 5. The floor nozzle head 1 also includes a suction nozzle 6 with a nozzle which reduces the sliding resistance of the device Suction opening 8 with slide rail 7. The spray nozzle 2 is supplied with cleaning fluid via a hose 9 with a pump connected to it. The cleaning liquid is sprayed from the spray nozzle 2 - approximately in the working width of the suction opening 8 - onto the floor to be cleaned. In general, at the same time as the spraying, previously applied cleaning liquid is drawn off together with already loosened dirt via the suction nozzle 6 in the direction of the arrow 10 into a dirty liquor container.

Erfindungsgemäß wird in als Lager dienenden Aufnahmelöchern 11 der Seitenwände 5 die Tragschiene 12 eines insgesamt mit 13 bezeichneten Bürst- oder Borststreifens schwenkbar so befestigt, daß er wie in Fig. 2 beim Schieben des Bodendüsenkopfes 1 in Pfeilrichtung 14 (Fig. 2) in eine inaktive Stellung 15 (fast) bodenfrei wegklappt, aber beim Ziehen in Pfeilrichtung 16 in eine aktive Stellung 17 ge­gen einen Anschalg, beispielsweise gegen eine Wand der Saugöffnung 8 umklappt. Auch in der inaktiven Stellung 15 kann ein Anschlag 18 für den Borststreifen 13 vorgesehen werden, der gewährleistet, daß der Borststreifen 13 nicht vollständig sondern fast bodenfrei gehalten und daher bei Umkehrung der Bewegung - vom Schieben zum Ziehen - selbsttätig in die aktive Stellung 17 umgeklappt wird.According to the invention, the mounting rail 12 of a brush or bristle strip, generally designated as 13, is pivotally fastened in mounting holes 11 of the side walls 5 serving as a bearing, such that it is inactive as shown in FIG. 2 when the floor nozzle head 1 is pushed in the direction of the arrow 14 (FIG. 2) Position 15 folds away (almost) without a floor, but when pulled in the direction of arrow 16 folds into an active position 17 against an impact, for example against a wall of the suction opening 8. Even in the inactive position 15, a stop 18 can be provided for the bristle strip 13, which ensures that the Bristle strip 13 is not kept completely but almost free of soil and is therefore automatically folded into the active position 17 when the movement is reversed - from pushing to pulling.

Im Ausführungsbeispiel nach Fig. 1 werden im Bereich der Aufnahme­löcher 11 des Borststreifens 13 innerhalb von dessen Borsten 19 Lücken 20 und außerhalb der Seitenwände 5 weitere Borstenbüschel 21 dargestellt. Durch die Lücken 20 und die Borstenbüschel 21 werden eine einfache Montage des Borststreifens 13 und zugleich eine siche­re Lagerung in den Aufnahmelöchern 11 gewährleistet.In the exemplary embodiment according to FIG. 1, gaps 20 are shown in the region of the receiving holes 11 of the bristle strip 13 within its bristles 19 and 5 additional tufts of bristles 21 outside the side walls. The gaps 20 and the tufts of bristles 21 ensure simple assembly of the bristle strip 13 and, at the same time, secure storage in the receiving holes 11.

Besonders vorteilhaft ist es, wenn die Aufnahmelöcher 11 nach Fig. 3 als Segmentaussparungen in etwa in Form eines bevorzugt in einen kleineren Vollkreis übergehenden Viertel-Kreis-Ausschnitts ausgebildet werden. In diesem Fall können die Radien des insgesamt mit 22 bezeichneten Segmentauschnitts zugleich als Anschalg 23 für das Feststellen des Borststreifens 13 beim Ziehen des Bodendüsen­kopfes 1 in Pfeilrichtung 16 und als Anschlag 24 beim Schieben in Pfeilrichtung 14 ausgebildet werden. Nach Fig. 3 wird die U-förmige Tragschiene 12 in den Segmentausschnitten 22 der Aufnahmelöcher 11 beim Hin- und Herschwenken ständig im wesentlichen an drei Punkten, nämlich an den Spitzen 25 der U-Schenkel 26 und an dem annähernd kreisförmigen Boden 27 der U-Form gehalten.It is particularly advantageous if the receiving holes 11 according to FIG. 3 are designed as segment recesses approximately in the form of a quarter-circle section which preferably merges into a smaller full circle. In this case, the radii of the segment cutout, designated as a whole by 22, can at the same time be designed as a bellows 23 for fixing the bristle strip 13 when pulling the floor nozzle head 1 in the direction of arrow 16 and as a stop 24 when pushing in the direction of arrow 14. 3, the U-shaped mounting rail 12 is in the segment cutouts 22 of the receiving holes 11 when pivoting back and forth essentially at three points, namely at the tips 25 of the U-legs 26 and on the approximately circular bottom 27 of the U- Kept in shape.
