Abstract
Description
Die Erfindung betrifft einen fahrbaren Bodenreinigungsautomaten mit integrierten Frisch- und Schmutzflüssigkeitsabteilen, mit einem reguliert aus dem Frischflüssigkeitsabteil zu versorgenden Reinigungsrotor sowie mit einer in das Schmutzflüssigkeitsabteil fördernden Saugdüse und mit einem Bedienungselemente aufnehmenden Lenker.The invention relates to a mobile floor cleaning machine with integrated fresh and dirty liquid compartments, with a cleaning rotor to be supplied from the fresh liquid compartment, as well as with a suction nozzle conveying into the dirty liquid compartment and with a handlebar receiving control elements.
Ein bereits in der Praxis angewendeter Reinigunsautomat dieser Art besitzt an seiner Unterseite eine Rotoraufnahme, die mit einem Zubehörteil, insbesondere einer Bürste oder einem Treibteller mit Pad, zu kuppeln ist, indem das Zubehörteil auf den Boden gelegt und das Gerät über das Zubehörteil gefahren sowie darauf aufgesetzt wird. Zum Einrasten des Zubehörteils ist dann lediglich ein kurzes Antippen des dem Rotor zugeordneten Motors erforderlich.A cleaning machine of this type already used in practice has on its underside a rotor holder which can be coupled to an accessory, in particular a brush or a drive plate with a pad, by placing the accessory on the floor and moving the device over and over the accessory is put on. All that is required to snap the accessory into place is a brief tap on the motor assigned to the rotor.
Bei Anwendung wird asu einem gesonderten Frischwassertank Reinigungsflüssigkeit über den Rotor auf den zu behandelnden Fußboden aufgespritzt. Zugleich wird mit dem Rotor gescheuert. Mit Hilfe einer beim Vorwärtsschieben des Automaten dem Rotor nachfolgenden balkenartigen Wassersaugdüse wird das nach dem Scheuern noch verbleibende Schmutzwasser wieder aufgesaugt, so daß der Boden in einem Arbeitsgang gründlich gescheuert und gleichzeitig gewissermaßen trockengewischt, das heißt abgesaugt, werden kann.When using, a separate fresh water tank is used to spray cleaning liquid onto the floor to be treated via the rotor. At the same time, the rotor is scrubbing. With the help of a bar-like water suction nozzle that follows the rotor when the machine is pushed forward, this is still possible after scrubbing Remaining dirty water is sucked up again, so that the floor can be scrubbed thoroughly in one operation and at the same time wiped dry to a certain extent, i.e. sucked off.
Das Maß der Frischflüssigkeitszufuhr zum Reinigungsrotor soll, z.B. in Abhängigkeit von der zu beseitigenden Verschmutzung, veränderbar sein. Bei im Gebrauch befindlichen Geräten wird die Flüssigkeitszufuhr zum Rotor mit einem Elektroventil geöffnet und anschließend mit Hilfe eines Handventils reguliert. Dieses Handventil muß natürlich immer im Bereich unterhalb des Flüssigkeitstanks, also in Bodennähe, montiert werden, Es ist daher nur mühsam zu bedienen. Ein weiteres Problem besteht darin, daß der Frischflüssigkeitsdruck von der Menge der Frischflüssigkeitsreserve abhängt. Diese Schwierigkeit wird besonders gravierend, wenn ein flexibler Flüssigkeitstank, bei dem beispielsweise die Zwischenwand zwischen Frisch- und Schmutzflüssigkeit als dichte Membran oder Wassersack ausgebildet ist, verwendet wird.The amount of fresh liquid supply to the cleaning rotor should, e.g. be changeable depending on the pollution to be removed. For devices in use, the liquid supply to the rotor is opened with an electro valve and then regulated with the help of a manual valve. This manual valve must of course always be installed in the area below the liquid tank, i.e. close to the ground. It is therefore difficult to use. Another problem is that the fresh liquid pressure depends on the amount of fresh liquid reserve. This difficulty becomes particularly serious when a flexible liquid tank, in which, for example, the partition between fresh and dirty liquid is designed as a tight membrane or water bag, is used.
Der Erfindung liegt die Aufgabe zugrunde, für den eingangs genannten Reinigungsautomaten eine bequem zu bedienende Mengenregulierung der Frischflüssigkeitszufuhr zu schaffen, die auch bei Verwendung eines flexiblen Tanks einzusetzen ist. Die erfindungsgemäße Lösung ist gekennzeichnet durch eine Wechselstrom-Schwingkolbenpumpe zum Regulieren der Frisch flüssigkeitszufuhr zum Reinigungsrotor. Vorzugsweise wird die Förderleistung durch eine der Schwingkolbenpumpe vorgeschaltete Elektronik bzw. einem Impulsgeber mit etwa zehn Stufen reguliert.The invention has for its object to provide a convenient to use quantity control of the fresh liquid supply for the cleaning machine mentioned above, which can also be used when using a flexible tank. The solution according to the invention is characterized by an AC oscillating piston pump for regulating the freshness liquid supply to the cleaning rotor. The delivery rate is preferably regulated by electronics upstream of the oscillating piston pump or a pulse generator with approximately ten stages.
Durch die Erfindung wird erreicht, daß die Steuermittel der Frischflüssigkeitszufuhr in den Lenker des Automaten bzw. in dessen Armaturenbrett zu verlegen ist. Die Bedienung kann also ohne körperliche Anstrengung und zugleich mit größerer Präzision, wegen der besseren Beobachtungsmöglichkeit des Fußodens erfolgen. Beispielsweise werden zum Regulieren der Frischflüssigkeitsmenge zwei Tasten, nämlich eine Plus- Taste und eine Minus-Taste, die im Lenker bzw. im Armaturenbrett des Automaten integriert sind, vorgesehen.It is achieved by the invention that the control means of the fresh liquid supply is to be laid in the handlebar of the machine or in its dashboard. The operation can therefore be carried out without physical effort and at the same time with greater precision because of the better observation of the foot. For example, two buttons, namely a plus button and a minus button, which are integrated in the handlebar or in the dashboard of the machine, are provided for regulating the amount of fresh liquid.
Natürlich ist es zum Betrieb des erfindungsgemäßen Automaten auch vorteilhaft, jeweils noch zur Verfügung stehende Frischflüssigkeitsmengen zu erkennen. Vorzugsweise werden hierzu im Frischflüssigkeitsabteil des Tanks Sonden zum Erfassen des augenblicklichen Füllstands vorgesehen. Insbesonders sollen diese Sonden über einen bei Eintauchen (der Sonden) in die Frischflüssigkeit durchschaltenden, integrierten Schaltkreis (IC) mit Wechselspannung versorgt werden. Der IC soll also durchschalten, wenn und solange die Sonde von der jeweiligen Flüssigkeit bedeckt ist. Auf diese Weise kann der Füllstand beispielsweise durch Leuchtdioden, Zeigerinstrumente, Warnlichter oder dergleichen angezeigt werden.Of course, it is also advantageous for the operation of the machine according to the invention to recognize fresh liquid quantities that are still available. For this purpose, probes are preferably provided in the fresh liquid compartment of the tank for detecting the current fill level. In particular, these probes are to be supplied with alternating voltage via an integrated circuit (IC) which switches through when the (probes) are immersed in the fresh liquid. The IC should switch through when and as long as the probe is covered by the respective liquid. In this way, the fill level can be displayed, for example, by light-emitting diodes, pointer instruments, warning lights or the like.
Unter dem Begriff "Frischflüssigkeit" wird im vorliegenden Zusammenhang eine Mischung von Frischwasser und Reinigungskonzentrat verstanden. "Schmutzflüssigkeit" ist vom Boden aufgesaugte Frischflüssigkeit. Der Einfachheit halber wird auch von Frischwasser bzw. Schmutzwasser gesprochen.In the present context, the term “fresh liquid” is understood to mean a mixture of fresh water and cleaning concentrate. "Dirty liquid" is fresh liquid drawn up from the floor. For the sake of simplicity, we also speak of fresh water or dirty water.

Die Fig. 1 bis 3 zeigen einen fahrbaren Bodenreinigungsautomaten in drei verschiedenen Ansichten, Projektionen bzw. Schnitten. Der Automat besteht aus einem insgesamt mit 1 bezeichneten Wagen mit Fahrrollen 2 und Stützrol len 3 sowie Lenker 4 mit Bedienungspult. Einen grossen Teil des Innern des Wagens 1 nimmt ein insgesamt mit 5 bezeichneter Flüssigkeitstank ein. Dieser besitzt einen Deckel 6 mit daran befestigtem, eine Skala aufweisenden Dosierbehälter 7. Die Skala soll dem gewünschten Mischungsverhältnis von Frischwasser zu Reinigungskonzentrat entsprechen. Bei geöffnetem Deckel 6 kann der Dosierbehälter 7 nach dem vorgegebenen Mischungsverhältnis gefüllt werden. Durch Schließen des Deckels 6 in Schließrichtung 8 entleert sich der Inhalt 9 des Dosierbehälters 7 in den Flüssigkeitstank 5.1 to 3 show a mobile floor cleaning machine in three different views, projections or sections. The machine consists of a total of 1 car with
Der Flüssigkeitstank 5 besteht aus einem Frischwasserabteil 10 und einem Schmutzwasserabteil 11. Im Ausführungsbeispiel werden im Frischwasserabteil 10 mehrere Sonden 12 zum Erfassen und Anzeigen des Füllstands vorgesehen. Mit einem integrierten Schaltkreis bzw. IC können die Sonden mit einer Wechselspannung (um ein galvanisches Abtragen der Sonden zu verhindern, wird Gleichstrom nicht verwendet) beaufschlagt. Der IC schaltet durch, sobald und solange die Sonden von einer Flüssigkeit bedeckt sind. Der Füllstand kann durch Leuchtdioden, Zeigerinstrumente, Warnlichter oder dergleichen angezeigt werden.The liquid tank 5 consists of a
Das Frischwasserabteil 10 und das Schmutzwasserabteil 11 werden durch eine Zwischenwand 13 voneinader getrennt. Die Zwischenwand kann wie in Fig. 2 oder 3 eine feste Trennwand zwischen den beiden Abteilen 10 und 11 darstellen. Sie kann zur Anpassung an das jeweilige Mengenverhältnis auch seitlich verschiebbar bzw. verstellbar zur Trennung der Abteile 10 und 11 angeordnet werden. In den Fig. 4 und 5 wird eine feste Zwischenwand 13 mit darin eingesetzten Filterkerzen 14 schematisch dargestellt. Anstelle einer festen Zwischenwand 13 kann nach Fig. 6 und 7 auch eine flexible Zwischenwand 15 zur Abrennung des Frischwasserabteils 10 vom Schmutzwasserabteil 11 verwendet werden.The
Nach Fig. 1 und 2 wird an der Unterseite des Wagens 1 ein verstellbarer Maschinenrahmen 16 befestigt, der aus mindestens zwei etwa radial in Bezug auf den auf der Unterseite 17 des Wagens 1 in einer Aufnahme 18 eingekuppelten Reinigungsrotor 19 auseinander bzw. ineinander zu schiebenden Rahmenteilen 20, 21 besteht. Die Rahmenteile 20, 21 sind also in den in Fig. 2 dargestellten Pfeilrichtungen 22 bzw. 23 in Richtung auf die Aufnahme 18 radial verschiebbar. Durch eine solche Verstellung des Maschinenrahmens 16 ist es möglich, einen Rotor 19 mit kleinerem Durchmesser durch einen Rotor 24 mit größerem Durchmesser zu ersetzen und den von dem Maschinenrahmen 16 zumindest teilweise umschlossenen Maschinenraum bzw. Waschraum in und unter dem Reinigunsrotor 19 bzw. 24 möglichst gut an dessen Durchmesser anzupassen.1 and 2, an
An der Rückseite des Automaten, das heißt auf der vom Reinigungsrotor 19 bzw. 24 abgewandten Seite der Fahrrollen 2 wird nach Fig. 1 und 2 eine Saugdüse 25 vor gesehen, die die Form eines Saugbalkens haben kann. Auf der Vorderseite des Automaten, als der Saugdüse 25 gegenüber sowie an den Seiten des Automaten, das heißt seitlich des Rotors, wird nach Fig. 1 und 4 ein am Maschinenrahmen 16 hängender Vorhang 26 angebracht. Dadurch wird erreicht, daß nach den von dem Maschinenrahmen 16 bzw. Vorhang 26 abgeschirmten Seiten Wasser praktisch nicht - jedenfalls bei ebenem Boden - abfließen kann.On the back of the machine, that is to say on the side of the
Anhand von Fig. 8 wird ein Ausführungsbeispiel des Rotorwechselsystems beschrieben. Zum Einkuppeln eines z.B. als Bürste ausgebildeten Reinigungsrotors 19 in die insegesamt mit 18 bezeichnete Aufnahme des Automaten wird zunächst ein als Kupplung vorgesehener Mitnehmerstern 27 (mit Motor 28) in Pfeilrichtung 29 angehoben. Daraufhin wird der Rotor 19 unter die Maschine geschoben, bis er zum Vorzentrieren an einen Zentrierzapfen anstößt. Schließlich wird der Motor 28 in Pfeilrichtung 29 abgesenkt, derart, daß der Mitnehmerstern 27 in eine Mitnehmer-Aufnahme des Rotors 19 eintritt und dort einrastet.An exemplary embodiment of the rotor changing system is described with reference to FIG. 8. For coupling a e.g.
Wichtig in diesem Zusammenhang ist die beispielsweise durch den Motor 28 hindurchgeführte Frischwasserzufuhr mit einer Verbindungsleitung 30 zwischen Frischwasserabteil 10 und Reinigungsrotor 19. Diese Verbindungsleitung 30 enthält eine Wechselstrom-Schwingkolbenpumpe 31 zum Regulieren der Frischwasserzufuhr zum Rotor 19. Zum Steuern der Schwingkolbenpumpe 31 dient eine Impulsgeber-Elektronik 32, die mit einer (nicht gezeichneten) Bedienungstastenanordnung im Armaturenbrett oder dergleichen einerseits und mit der Schwingkolbenpumpe 31 andererseits über eine Leitung 33 verbunden wird. Vorzugsweise kann die Elektronik 32 auch noch eine von den Sonden 12 nach Fig. 3 ausgehende Steuerverbindung sowie eine weitere ebenfalls nicht gezeichnete Steuerverbindung zum Motor 28 besitzen um bei Flüssigkeitsmangel im Abteil 10 ein Trockenlaufen des Reinigungsrotors 19 zu vermeiden.In this context, it is important to supply fresh water, for example through the
Der fahrbare Bodenreinigungsautomat kann wahlweise aus einer Batterie oder unmittelbar vom Netz betrieben werden. Bei Batteriebetrieb, z.B. mit 24 Volt, wird ein Batteriesatz in ein Batteriefach 34 nach Fig. 1 der Maschine fertig verkabelt eingeschoben und an das Maschinennetz angeschlossen. Bei Netzbetrieb ( 220 Volt, Wechselstrom) eines an sich für den Batteriebetrieb ausgelegten Automaten wird in das Batteriefach 34 ein einen Trafo und einen Gleichrichter enthaltendes Netzteil eingeschoben und mit dem Maschinennetz verbunden.The mobile floor cleaning machine can be operated either from a battery or directly from the mains. In the case of battery operation, for example with 24 volts, a battery set is inserted into a battery compartment 34 according to FIG. 1 of the machine in a fully wired manner and connected to the machine network. During mains operation (220 volts, alternating current) of an automatic machine designed for battery operation, a power pack containing a transformer and a rectifier is inserted into the battery compartment 34 and connected to the machine network.
