Description

Die Erfindung betrifft einen fahrbaren Reinigungsautomaten mit mitgeführten Reinigungsmittel- und Schmutzbehältern, mit einer in einer eine eigene Fahrrolle aufweisenden Sprüh- und Saugdüsenanordnung angeordneten Sprühdüse zum Auftragen von Reinigungsmittel auf eine zu reinigende Fläche sowie mit einer Saugdüse zum Zurücksaugen des ausgebrachten Reinigungsmittels, wobei der Reinigungsmittelbehälter zusammen mit einer zugehörigen Druckpumpe zum Ausbringen des Reinigungsmittels in ein mit Hilfe einer Führungsdeichsel fahr- und lenkbares Chassis integriert ist und das Chassis eine Aufnahme für ein Saugaggregat mit integriertem Schmutzbehälter besitzt.The invention relates to a mobile cleaning machine with detergent and dirt containers carried along, with a spray nozzle arranged in a spray and suction nozzle arrangement which has its own castor for applying cleaning agent to a surface to be cleaned, and with a suction nozzle for sucking back the detergent applied, the detergent container together is integrated with an associated pressure pump for dispensing the cleaning agent into a chassis which can be driven and steered with the aid of a guide drawbar and the chassis has a receptacle for a suction unit with an integrated dirt container.

Ein derartiger Bodenreinigungsautomat ist aus der DE-A-2019646 bekannt. Dieses Gerät weist einen verfahrbaren Wagen mit einer getrennt dazu verfahrbaren Sprüh- und Saugdüsenanordnung auf, die über Schläuche mit dem verfahrbaren Wagen bzw. den darauf angeordneten Vorrichtungen verbunden ist.Such a floor cleaning machine is known from DE-A-2019646. This device has a movable carriage with a spray and suction nozzle arrangement which can be moved separately from it and which is connected by hoses to the movable carriage or the devices arranged thereon.

Ein weiterer Bodenreinigungsautomat ist in der DE-A-2328941 beschrieben. In diesem Gerät sind alle Funktionen und Behälter in einem einzigen zweirädrigen Wagen mit Deichsel integriert. Ein solcher Automat ist daher nur als Spezialgerät für bestimmte Reinigungsaufgaben ausgelegt. In der DE-A-2449021 wird ein tragbares Bodenreinigungsgerät ähnlicher Art beschrieben, das ebenfalls nur für den Spezialzweck, für den es jeweils konzipiert ist, einzusetzen ist. Die beiden bekannten Geräte besitzen nur ein einachsiges Fahrwerk, um es der Bedienungsperson zu ermöglichen, den Anstellwinkel von Sprühdüsen und Saugdüsen den individuellen Bedürfnissen anzupassen. Bei Bearbeitung großer Flächen, für die diese Spezialgeräte eigentlich ausgelegt sind, führt die ständige Anpassung des Anstellwinkels jedoch zu einer vorzeitigen Ermüdung.Another floor cleaning machine is described in DE-A-2328941. In this device, all functions and containers are integrated in a single two-wheel cart with a drawbar. Such a machine is therefore only designed as a special device for certain cleaning tasks. DE-A-2449021 describes a portable floor cleaning device of a similar type which is likewise only to be used for the special purpose for which it is designed. The two known devices only have one uniaxial chassis to allow the operator to adjust the angle of spray and suction nozzles to individual needs. When machining large areas for which these special devices are actually designed, however, the constant adjustment of the angle of attack leads to premature fatigue.

Ein weiterer Reinigungsautomat wird in der DE-A-3445200 beschrieben. Dieser als Sprühextraktionsgerät ausgebildete Automat soll im wesentlichen aus drei Baugruppen, nämlich einem Bedienungsteil, einem Saugbehälter und einem Sprühteil bestehen. Die Baugruppen sollen jeweils kastenförmig ausgebildet und in drei vertikal übereinanderliegenden, parallelen Ebenen voneinander lösbar angesetzt werden. Die einzelnen Baugruppen sollen zerlegbar und wieder zusammensetzbar sein, um es zu ermöglichen, das Gerät mit wenigen Handgriffen in einen kompakten, separaten Naß- und Trockensauger zu verwandeln. Ein wesentlicher Nachteil des bekannten Geräts besteht jedoch darin, daß wegen der getrennten Verwendbarkeit der Sprüh- und Saugeinrichtungen getrennte Sprühund Saugdüsen mit jeweils besonderen Zuleitungen vorgesehen werden müssen. Zu dem umständlichen Arbeiten mit zwei getrennten Düsen kommt hinzu, daß der die Saug- und Druckaggregate sowie die zugehörigen Behälter enthaltende Wagen von der Bedienungsperson hinterher gezogen werden muß.Another cleaning machine is described in DE-A-3445200. This machine, which is designed as a spray extraction device, should essentially consist of three subassemblies, namely an operating part, a suction container and a spray part. The modules should each be box-shaped and releasably attached to one another in three vertically superimposed, parallel planes. The individual assemblies should be able to be dismantled and reassembled to enable the device to be converted into a compact, separate wet and dry vacuum cleaner in just a few simple steps. A major disadvantage of the known device, however, is that because of the separate usability of the spray and suction devices, separate spray and suction nozzles, each with special feed lines, must be provided. In addition to the cumbersome work with two separate nozzles, the operator must pull the carriage containing the suction and pressure units and the associated containers.

Aus der US-A-4,616,378 ist ein verfahrbares Sauggerät bekannt, bei welchem die Saugdüse an einer am Chassis angeordneten Kupplung befestigt ist. Aus der US-A-3,981,596 ist schließlich ein verfahrbares Sprüh- und Poliergerät bekannt, bei welchem eine Sprühdüsenanordnung an dem Chassis des Gerätes angekuppelt ist.From US-A-4,616,378 a movable suction device is known, in which the suction nozzle is attached to a coupling arranged on the chassis. Finally, from US-A-3,981,596 a movable spraying and polishing device is known, in which a spray nozzle arrangement is coupled to the chassis of the device.

Der Erfindung liegt die Aufgabe zugrunde, einen fahrbaren Reinigungsautomaten so auszubilden, daß eine getrennte Verwendung des Saugaggregats zwar möglich ist, aber bei Verwendung des Sprühaggregats zusammen mit dem Saugaggregat ein ermüdungsfreies Arbeiten auch auf größeren Flächen lediglich durch Schieben eines einzigen Wagens mit stets gleichem, optimalem Anstellwinkel sowohl der Sprühdüsen als auch der Saugdüsen möglich ist. Auch wenn das Sprüh- und Saugdüsensystem mit dem die zugehörigen Aggregate und Behälter aufnehmenden Wagen fest verbunden wird, soll eine Reinigung des Fußbodens bis an die äußersten Kanten des Raums zu gewährleisten sein.The invention has for its object to design a mobile cleaning machine so that a separate use of the suction unit is possible, but when using the spray unit together with the suction unit fatigue-free work even on larger areas only by pushing a single trolley with the same, optimal Angle of attack of both the spray nozzles and the suction nozzles is possible. Even if the spray and suction nozzle system is firmly connected to the trolley that holds the associated units and containers, the floor should be cleaned to the very edges of the room.

Die erfindungsgemäße Lösung besteht für den fahrbaren Reinigungsautomaten eingangs genannter Art darin, daß eine Kupplung zum Befestigen der Sprüh- und Saugdüsenanordnung als Anschlagbügel an der Vorderseite des Chassis befestigt ist und die Sprüh- und Saugdüsenanordnung auf der Kupplung quer zur Fahrtrichtung des Automaten verschiebbar zu justieren ist.The solution according to the invention for the mobile cleaning machine of the type mentioned at the outset is that a coupling for fastening the spray and suction nozzle arrangement is attached as a stop bracket to the front of the chassis and the spray and suction nozzle arrangement on the coupling can be adjusted to be displaceable transversely to the direction of travel of the machine .

Durch die Erfindung wird ein Reinigungsautomat mit einem fahr- und lenkbaren Chassis zur integrierten Aufnahme eines Laugentanks und einer Druckpumpe geschaffen, der einen Platz zum losen Einsetzen eines Saugaggregats mit Schmutzwasserbehälter aufweist. Das Saugaggregat kann daher als getrennter Staub- oder Wassersauger verwendet werden. Es besitzt aber in der Kombination mit dem erf indungsgemäßen Reinigungsautomaten einen Anschluß zu einer gemeinsamen Sprüh- und Saugdüsenanordnung, die an einer Kupplung des fahrbaren Reinigungsautomaten zu befestigen ist und selbst mindestens eine Fahrrolle besitzt, so daß der ganze Automat wie ein drei- oder vierrädriger Wagen über den zu reinigenden Fußboden zu fahren ist. Da außerdem das die Sprüh- und Saugdüse enthaltende Aggregat auf einem Bügel quer zur Fahrtrichtung des Wagens justierbar an diesem zu arretieren sein soll, kann das Düsenaggregat jeweils an die eine oder andere Seite so weit verschoben werden, daß durch Schieben des Wagens an einer Wand entlang der Fußboden bis unmittelbar an die Wand heran gleichmäßig zu reinigen oder in sonstiger Weise zu behandeln ist.The invention provides an automatic cleaning machine with a drivable and steerable chassis for the integrated accommodation of an alkali tank and a pressure pump, which has a place for the loose insertion of a suction unit with a dirty water tank. The suction unit can therefore be used as a separate vacuum or water vacuum. However, in combination with the cleaning machine according to the invention, it has a connection to a common spray and suction nozzle arrangement which is to be attached to a coupling of the mobile cleaning machine and itself has at least one castor, so that the whole machine is like a three- or four-wheeled carriage is to be driven over the floor to be cleaned. Since also that containing the spray and suction nozzle Unit on a bracket transverse to the direction of travel of the car to be locked on this, the nozzle unit can be moved to one side or the other so far that by pushing the car on a wall along the floor up to the wall evenly is to be cleaned or otherwise treated.

Ein weiterer Vorteil der Erfindung besteht darin, daß die Düsenanordnung ein eigenes, einen stets gleichen, optimalen Anstellwinkel sowohl der Spritzdüsen als auch der Sauglippen gewährleistendes Fahrwerk besitzt. Je nach Art des zu behandelnden Fußbodens kann also ein besonderes Sprüh-Saug-Aggregat verwendet oder der optimale Anstellwinkel der Düsen usw. vor Aufnahme der Arbeit justiert werden.Another advantage of the invention is that the nozzle arrangement has its own chassis, which always ensures the same, optimal angle of attack of both the spray nozzles and the suction lips. Depending on the type of floor to be treated, a special spray-suction unit can be used or the optimal angle of attack of the nozzles etc. can be adjusted before starting work.

In Ausgestaltung sieht die Erfindung eine Führungsdeichsel mit einem integrierten Kabelhaken zum geordneten Aufbewahren des Netzkabels bei Nichtgebrauch bzw. als Aufhängevorrichtung für einen Tragekorb oder dergleichen vor. Wenn eine bügelförmige Deichsel zum Schieben des Reinigungsgeräts vorgesehen wird, ist es zweckmäßig, den Kabelhaken in beide Schenkel der bügelförmigen Deichsel zu integrieren.In an embodiment, the invention provides a guide drawbar with an integrated cable hook for orderly storing the mains cable when not in use or as a hanging device for a carrying basket or the like. If a bow-shaped drawbar is provided for pushing the cleaning device, it is expedient to integrate the cable hook in both legs of the bow-shaped drawbar.

Um zu erreichen, daß der Reinigungsmittelbehälter bzw. Laugentank direkt an einem Wasserhahn zu füllen ist, der umständliche Transport mit einem Wassereimer sich also erübrigt, wird der Reinigungsbehälter gemäß weiterer Ausgestaltung der Erfindung mit einem herausziehbaren Schlauch mit Einfülltülle, die an einen Wasserhahn unmittelbar anzuschließen ist, ausgestattet. Auf diese Weise wird auch eine Verstopfung oder Beschädigung der Druckpumpe durch mit einer Eimerbefüllung in den Behälter gelangende Verunreinigungen vermieden.In order to ensure that the detergent container or lye tank is to be filled directly at a tap, so that the cumbersome transport with a water bucket is unnecessary, the cleaning container is, according to a further embodiment of the invention, with a pull-out hose with a filler nozzle which is to be connected directly to a tap , fitted. In this way, clogging or damage to the pressure pump due to contamination from a bucket filling is avoided.

Schließlich ist es gemäß Weiterbildung der Erfindung vorteilhaft, in den Reinigungsmittelbehälter einen bis zum Behälterboden führenden Stutzen zum Absaugen der jeweiligen Restlauge einzubauen. Hierdurch erübrigen sich zusätzliche Entleerungsventile, die in der Praxis immer wieder zu Undichtheiten geführt haben.Finally, according to a further development of the invention, it is advantageous to install a nozzle leading to the bottom of the container for sucking off the respective residual liquor in the detergent container. This eliminates the need for additional drain valves, which have repeatedly led to leaks in practice.

Der Reinigungsautomat nach Fig. 1 und 2 besteht aus einem insgesamt mit 1 bezeichneten Chassis mit darin zusammen mit einer Druckpumpe 2 integriertem Reinigungsmittelbehälter 3. Das Chassis 1 besitzt im Ausführungsbeispiel ein Tragradpaar 4 und ein Lenkradpaar 5 sowie eine bügelförmige Deichsel 6 mit in die Oberseite der Deichselschenkel integrierter die Schenkel verbindender, hakenförmiger Kabelauflage 7. Letztere kann auch zum Anhängen eines Tragkorbs 8 mit entsprechendem Haken 9 dienen. Der Reinigungsmittelbehälter 3 besitzt einen herausziehbaren Schlauch mit Einfülltülle 10, die unmittelbar an einen Wasserhahn angeschlossen werden kann. Außerdem wird im Reinigungsmittelbehälter 3 ein zu dessen Boden 11 führender Stutzen 12 zum Absaugen von Restlauge vorgesehen.1 and 2 consists of a chassis designated as a whole with 1 with a detergent container 3 integrated therein together with a pressure pump 2. The chassis 1 in the exemplary embodiment has a pair of carrying wheels 4 and a pair of steering wheels 5 and a bow-shaped drawbar 6 with in the top of the Drawbar leg integrated the legs connecting, hook-shaped cable support 7. The latter can also be used to attach a support basket 8 with a corresponding hook 9. The detergent container 3 has a pull-out hose with filler nozzle 10, which can be connected directly to a tap. In addition, a nozzle 12 leading to the bottom 11 of the detergent container is provided for suctioning off residual liquor.

Ein wesentliches Merkmal des Chassis 1 ist eine Aufnahme 14 für ein insgesamt mit 15 bezeichnetes Saugaggregat mit integriertem Schmutzbehälter 16 und Saugpumpe 17 sowie eine im Ausführungsbeispiel als Anschlagbügel 18 ausgebildete Kupplung zum Befestigen einer eine eigene Fahrrolle 19 aufweisenden Sprüh- und Saugdüsenanordnung 20 nach Fig. 3. Das beispielsweise an einem Griff 21 aus seiner Position in der Aufnahme 14 des Chassis 1 herauszuhebende Saugaggregat 15 wird mit einem von seinem Saugstutzen 22 ausgehenden Saugschlauch 23 mit dem entsprechenden Sauganschluß 24 der Sprüh- und Saugdüsenanordnung 20 verbunden, wenn letztere an dem Anschlagbügel 18 befestigt ist. Zwischen dem Sprühund Saugdüsenaggregat 20 und dem Chassis 1 besteht eine weitere Verbindungsleitung, nämlich die Druckleitung 25 der Reinigungsmittel aus dem Behälter 3 fördernden Durckpumpe 2. Die Druckleitung 25 kann durch ein in der Deichsel 6 vorgesehenes Regelventil 26 geleitet werden, mit dem es möglich ist, die Menge des aufgesprühten Reinigungsmittels individuell zu regeln. Die Deichsel 6 kann außerdem ein Schaltpult 27 mit Stellknöpfen für die verschiedenen Aggregate enthalten.An essential feature of the chassis 1 is a receptacle 14 for a suction unit, generally designated 15, with an integrated dirt container 16 and suction pump 17, and a coupling, designed in the exemplary embodiment as a stop bracket 18, for fastening a spray and suction nozzle arrangement 20 according to FIG. 3, which has its own castor 19 The suction unit 15 to be lifted out of its position in the receptacle 14 of the chassis 1, for example by a handle 21, is connected to the corresponding suction connection 24 of the spray and suction nozzle arrangement 20 by a suction hose 23 starting from its suction nozzle 22, if the latter is attached to the stop bracket 18. Between the spray and suction nozzle assembly 20 and the chassis 1 there is a further connecting line, namely the pressure line 25 of the cleaning agent from the container 3-promoting pressure pump 2. The pressure line 25 can be passed through a control valve 26 provided in the drawbar 6, with which it is possible to regulate the amount of detergent sprayed individually. The drawbar 6 can also contain a control panel 27 with knobs for the various units.

Das eigentliche Sprüh- und Saugdüsenaggregat 20 wird in den Fig. 3 bis 6 näher dargestellt. Es besitzt eine Fahrrolle 19 bzw. ein Fahrrollenpaar, die zum definierten Vorgeben des Abstandes und des Anstellwinkels von Sprühdüse 28 und Sauglippen 29 vorgesehen ist. Grundsätzlich ist es möglich, das Chassis nur mit dem einen Tragradpaar 4 auszustatten, und die Fahrrolle 19 der Sprüh- und Saugdüsenanordnung 20 als einzige Lenkrolle des ganzen Reinigungsautomaten auszubilden.The actual spray and suction nozzle assembly 20 is shown in more detail in FIGS. 3 to 6. It has a roller 19 or a pair of rollers which is provided for the defined specification of the distance and the angle of attack of the spray nozzle 28 and suction lips 29. In principle, it is possible to equip the chassis with only one pair of carrying wheels 4 and to design the driving roller 19 of the spray and suction nozzle arrangement 20 as the only steering roller of the entire cleaning machine.

Das Sprüh- und Saugdüsenaggregat besitzt einen Ausläß, nämlich eine Sprühdüse 28, die bei Betrieb mit der Druckleitung 25 gekoppelt wird un einen Einlaß, nämlich eine Sauglippe 29, die bei Betrieb über ihren Sauganschlub 24 und dem Saugschlauch 23 mit dem Ansaugstutzen 22 des Saugaggregats 15 verbunden wird. Die im Ausführungsbeispiel eine Fahrrolle 19 aufweisende Rollendüse bzw. Sprüh- und Saugdüsenanordnung 20 wird mit einer die Düsen bzw. Sauglippen nach oben und nach den Seiten abschirmenden Haube 30 ausgestattet, die die Sprühstrahlen in jedem Falle auf den Fußboden lenkt.The spray and suction nozzle assembly has an outlet, namely a spray nozzle 28, which is coupled in operation to the pressure line 25 and an inlet, namely a suction lip 29, which in operation via its suction connection 24 and the suction hose 23 with the suction port 22 of the suction unit 15 is connected. The roller nozzle or spray and suction nozzle arrangement 20 which has a castor 19 in the exemplary embodiment is equipped with a hood 30 which shields the nozzles or suction lips upwards and to the sides and in each case directs the spray jets onto the floor.

Ein wesentliches Merkmal der erfindungsgemäßen Sprüh- und Saugdüsenanordnung an deren Verbindung zum Chassis 1 besteht in der seitlichen Verschiebbarkeit und Justierbarkeit des Düsenaggregats, derart, daß dieses nach rechts oder links in Bezug auf das Chassis zu versetzen ist und damit speziell auf die Kante zwischen Wand und Fußboden eines Raums zu richten ist.An essential feature of the spray and suction nozzle arrangement according to the invention at its connection to the chassis 1 is the lateral displaceability and adjustability of the nozzle assembly, in such a way that it can be displaced to the right or left in relation to the chassis and thus specifically to the edge between the wall and Floor of a room.

Nach dem Vorangehenden besitzt der Reinigungsautomat gemäß Fig. 1 bis 5 eine äußerst variable Einsatzmöglichkeit als Spühextraktionsgerät im eigentlichen, speziellen Sinne, als Staubsauger mit der Möglichkeit, ein Mikrofilter anzubringen, als Staub-Wassersauger und als Schaum-Reinigungsgerät zum Reinigen horizontaler Flächen. Der Automat ist wegen der Fahrrolle des Düsenaggegrats auch bei Bearbeitung größerer Flächen ermüdungsfrei zu bedienen, da er lediglich geschoben werden muß, da der für ein optimles Arbeisergebnis erforderliche Anstellwinkel der Spritzdüsen und Sauglippen voreinstellbar ist. Dabei zeichnet sich die Rollendüse aus durch ergonomisch leichten Lauf sowohl beim Sprüh- als auch beim Saugvorgang und durch die Möglichkeit beim Überschreiten von Schwellen oder an einer Fahrstuhlkante hoch geklappt und dadurch außer Betrieb gesetzt zu werden.After the foregoing, the cleaning machine has according to Fig. 1 to 5 an extremely variable application as a rinsing extraction device in the actual, special sense, as a vacuum cleaner with the possibility of attaching a microfilter, as a dust water cleaner and as a foam cleaning device for cleaning horizontal surfaces. The machine is fatigue-free to operate due to the roller of the nozzle aggregate, even when working on larger areas, since it only has to be pushed because the angle of attack of the spray nozzles and suction lips required for an optimal working result can be preset. The roller nozzle is characterized by ergonomically easy running both when spraying and when suctioning, and by the possibility of crossing thresholds or being folded up on an edge of the elevator and thus being put out of operation.

Wenn einmal nur das Saugaggregat benötigt wird, kann dieses am zugehörigen Griff einfach aus dem Chassis herausgehoben und ausgestattet mit einem Ansaugstutzen zum Aufsaugen von Schmutz und/oder Wasser verwendet werden. Der Reinigungserfolg kann in jedem Fall mit bloßem Auge überprüft werden, wenn der Schmutzbehälter wenigstens zum Teil mit einer durchsichtigen Wandung ausgestattet wird.If only the suction unit is needed, it can simply be lifted out of the chassis using the associated handle and equipped with an intake socket for sucking up dirt and / or water. The cleaning success can be checked with the naked eye if the dirt container is at least partially transparent Wall is equipped.
