Abstract

The machine has, in succession in the main direction of movement, a fluid applicator, a massaging device such as a brush roller and a discharge device. A switching device is used to set either the fluid applicator into operation with the massage device or the massage device into operation with the discharge device. The fluid applicator is an atomizer with a wide slit nozzle extending across the main direction of movement or with several spray nozzles arranged side by side. A time delay of a minute can be set between applying the fluid and removing same.

Description

Die Erfindung betrifft ein Bodenpflegegerät gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a floor care device according to the preamble of the first claim.

Bei einem bekannten Bodenpflegegerät dieser Art (DE-GM 76 36 603), das zur Teppichpflege bestimmt ist, befindet sich an der dem zu reinigenden Fußbodenbelag zugewandten Bodenwand des Gerätegehäuses eine Fluidaufbringvorrichtung, der in der Hauptbewegungsrichtung des Gerätes eine Massiereinrichtung für das Einmassieren von Feuchtigkeit in den Teppich nachgeordnet ist, wobei hinter dieser Massiereinrichtung eine Abführeinrichtung vorgesehen ist, durch die ein möglichst großer Anteil der auf den Fußboden aufgebrachten Flüssigkeit abgeführt wird. In der Hauptbewegungsrichtung liegt somit die Fluidaufbringvorrichtung an vorderster Stelle, welcher zunächst die Massiereinrichtung und dahinter die Abführeinrichtung nachfolgt. Im praktischen Betrieb dieses Bodenpflegegerätes wird eine Reinigungsflüssigkeit aus einem Querkanal der Fluidaufbringvorrichtung über eine kammartig ausgebildete Gummizunge auf den Teppich aufgebracht. Eine starre Schrägscheibenwalze der nachfolgenden Massiereinrichtung arbeitet die eingebrachte Reinigungsflüssigkeit in den Teppich ein, während die nachgeordnete Abführeinrichtung die mit Schmutzpartikeln versetzten freien Anteile dieser Reinigungsflüssigkeit wieder aufnimmt. Die drei Einrichtungen sind hierbei gleichzeitig wirksam.In a known floor care device of this type (DE-GM 76 36 603), which is intended for carpet care, there is a fluid application device on the floor wall of the device housing facing the floor covering to be cleaned, which has a massaging device for massaging moisture in the main direction of movement of the device is arranged downstream of the carpet, a discharge device being provided behind this massaging device, through which the largest possible proportion of the liquid applied to the floor is discharged. In the main direction of movement, the fluid application device is at the foremost position, which is followed first by the massaging device and then by the discharge device. In practical operation of this floor care device, a cleaning fluid is applied to the carpet from a transverse channel of the fluid application device via a comb-shaped rubber tongue. A rigid swashplate roller of the subsequent massaging device works the introduced cleaning liquid into the carpet, while the downstream discharge device removes the free portions of this cleaning liquid mixed with dirt particles resumes. The three institutions are effective at the same time.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Bodenpflegegerät gemäß dem Oberbegriff des ersten Anspruchs Maßnahmen zu treffen, durch welche ein erhöhter Wirkungsgrad bei der Schmutzaufnahme erzielt wird.The invention has for its object to take measures in a floor care device according to the preamble of the first claim, by means of which an increased efficiency in dirt absorption is achieved.

Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.This object is achieved according to the invention by the characterizing features of the first claim.

Vorteilhafte Ausgestaltungen der Erfindung und ein Verfahren zum Betreiben dieses Bodenpflegegerätes sind den weiteren Ansprüchen zu entnehmen.Advantageous embodiments of the invention and a method for operating this floor care device can be found in the further claims.

Bei einem Aufbau eines Bodenpflegegerätes gemäß der Erfindung werden zunächst nur die Fluidaufbringvorrichtung und die Massiereinrichtung aktiviert. In dieser Betriebseinstellung wird das für die Reinigung des betreffenden Fußbodenbelages, der neben einem Teppich auch durch einen Fliesenbelag oder andere glatte Böden gebildet sein kann, erforderliche Reinigungsfluid aufgetragen, wobei gleichzeitig durch die unmittelbar benachbarte Massiereinrichtung, die vorzugsweise für die Bearbeitung harter Fußbodenbeläge als Bürstenwalze ausgebildet ist, das Reinigungsmittel in die Tiefe des Teppichs eingearbeitet oder auf den glatten Bodenbelag aufgebürstet wird. Mit dieser Betriebseinstellung wird zunächst ein Teil oder auch die gesamte Fläche des zu reinigen Fußbodenbelages bearbeitet. Das Reinigungsmittel kann dadurch entsprechend lange, z. B. mindestens eine Minute auf die Schmutzpartikel des Bodenbelages einwirken und dieselben lösen und ggf. an sich binden. Infolge der sich daraus ergebenden verlängerten Einwirkungszeit wird das Reinigungsmittel effektiver genutzt und braucht daher nur in einer wesentlich verminderten Menge aufgetragen zu werden, als sie sonst bei sofortiger Absaugung erforderlich wäre. Es wird somit eine schädliche Durchnässung insbesondere von Teppichen vermieden und ein beachtlicher Teil des Reinigungsmittels eingespart. Erst nach dem Auftragen und Einarbeiten des Reinigungsmittels wird in einem zweiten Arbeitsgang nur die Massiereinrichtung und die Abführeinrichtung gemeinsam betrieben, so daß neben einer mechanischen Bearbeitung des mit Reinigungsmittel versetzten Fußbodenbelages und der dadurch erfolgenden nochmaligen Lockerung und Ablösung von Schmutzpartikeln diese Schmutzpartikel zusammen mit wenigstens einem großen Teil des aufgebrachten Reinigungsfluids aktiv abgesaugt werden. Das Aufbringen des Reinigungsmittels erfolgt dabei vorzugsweise durch Zerstäuben mit einer Flüssigkeitszerstäubungsvorrichtung die beispielsweise eine sich quer zur Hauptbewegungsrichtung erstreckende. Breitschlitzdüse oder mehrere nebeneinander angeordnete Sprühdüsen aufweist.When constructing a floor care device according to the invention, only the fluid application device and the massaging device are initially activated. In this operating setting, the cleaning fluid required for cleaning the floor covering in question, which in addition to a carpet can also be formed by a tile covering or other smooth floors, is applied, at the same time being formed by the immediately adjacent massaging device, which is preferably designed as a brush roller for processing hard floor coverings the detergent is worked into the depth of the carpet or brushed onto the smooth floor covering. With this operating setting, part or all of the surface of the floor covering to be cleaned is first processed. The detergent can be long, z. B. act for at least one minute on the dirt particles of the floor covering and loosen them and bind to them if necessary. As a result of the resulting longer exposure time, the cleaning agent is used more effectively and therefore only needs one to be applied in a significantly reduced amount than would otherwise be required with immediate suction. Harmful drenching, especially of carpets, is avoided and a considerable part of the cleaning agent is saved. Only after the application and incorporation of the cleaning agent, only the massaging device and the discharge device are operated together in a second operation, so that in addition to mechanical processing of the flooring mixed with cleaning agent and the subsequent loosening and detachment of dirt particles, these dirt particles together with at least one large one Part of the applied cleaning fluid can be actively suctioned off. The cleaning agent is preferably applied by atomization with a liquid atomization device, for example one that extends transversely to the main direction of movement. Has wide slot nozzle or several spray nozzles arranged side by side.

Das Bodenpflegegerät kann dabei als eigenständiges Reinigungsgerät mit allen für das Aufbringen des Reinigungsmittels, dem Antrieb der Massiereinrichtung und der Abführeinrichtung notwendigen Betriebseinrichtungen aufweisen, also insbesondere auch ein Sauggebläse besitzen, es kann jedoch auch als Vorsatzgerät zu einem Staubsauger ausgebildet sein, der zumindest das Sauggebläse aufnimmt und ggf. auch ein Bereitstellungsbehältnis für das Reinigungsfluid aufweist. Die Verbindung zwischen diesem Vorsatzgerät erfolgt dann über geeignete flexible Leitungsverbindungen sowohl für die Abführung der angesaugten Luft, -Wasser und Schmutz-Mischung bzw. zur Zuführung des Reinigungsfluids zur Sprüheinrichtung und ggf. elektrische Leitungen für den Antriebsmotor der Massiereinrichtung.The floor care device can have as an independent cleaning device with all the operating devices necessary for applying the cleaning agent, the drive of the massaging device and the discharge device, i.e. in particular it can also have a suction fan, but it can also be designed as a front device for a vacuum cleaner that at least receives the suction fan and possibly also has a supply container for the cleaning fluid. The connection between this attachment then takes place via suitable flexible line connections both for the removal of the sucked-in air, water and dirt mixture or for supplying the cleaning fluid to the spraying device and, if necessary, electrical lines for the drive motor of the massaging device.
