Description

Die Erfindung betrifft einen Reinigungskopf für ein Reinigungsgerät zur Nassreinigung von Bodenflächen mit einem Gehäuse, einem mit dem Gehäuse fest oder schwenkbeweglich verbundenen Saugstutzen zum Anschluss eines Saugaggregates, einer Einrichtung zur Abgabe eines Reinigungsmittels und mindestens einer an einer Unterseite des Gehäuses angeordneten schlitzförmigen Saugöffnung zum Absaugen des Reinigungsmittels von einer Bodenfläche. Der Saugstutzen mündet in einen Saugraum des Gehäuses ein, mit dem auch die Saugöffnung zum Absaugen des Reinigungsmittels verbunden ist.The invention relates to a cleaning head for a cleaning device for wet cleaning of floor surfaces with a housing, a fixed or pivotally connected to the housing suction nozzle for connecting a suction unit, a device for dispensing a cleaning agent and at least one arranged on a bottom of the housing slit-shaped suction opening for the suction of Detergent from a floor surface. The suction nozzle opens into a suction chamber of the housing, with which the suction opening for sucking the cleaning agent is connected.

Ein Reinigungskopf mit den vorstehend beschriebenen Merkmalen ist aus DE 100 03 883 C1 bekannt. Der bekannte Reinigungskopf weist an seiner Unterseite einen matten- oder vliesförmigen Reinigungsbelag auf, über den ein flüssiges Reinigungsmittel auf eine zu reinigende Bodenfläche aufgebracht wird. In Bewegungsrichtung vor und hinter dem Reinigungsbelag sind Saugöffnungen vorgesehen, um das Reinigungsmittel wieder von der Bodenfläche abzusaugen. Das Reinigungsverfahren wird als Sprühextraktionsverfahren bezeichnet und dient u.a. dazu, einen textilen Bodenbelag über viele Jahre in einem neuwertigen, ansehnlichen Zustand zu erhalten. Bei der Anwendung des Reinigungskopfes auf einem textilen Bodenbelag ist nachteilig, dass das Reinigungsmittel nur oberflächlich auf die Bodenfläche aufgetragen und nicht mechanisch in den textilen Belag eingearbeitet wird. Um eine ausreichende Reinigungswirkung zu erzielen, muss eine relativ große Menge an Reinigungsmittel eingesetzt werden. Nach dem Absaugen des Reinigungsmittels verbleibt eine hohe Restfeuchtigkeit auf dem Boden.A cleaning head with the features described above is out DE 100 03 883 C1 known. The known cleaning head has on its underside a mat or fleece-shaped cleaning pad, via which a liquid cleaning agent is applied to a floor surface to be cleaned. In the direction of movement in front of and behind the cleaning pad suction openings are provided to suck the cleaning agent again from the bottom surface. The cleaning process is referred to as a spray extraction process and is used, inter alia, to obtain a textile floor covering over many years in a new, respectable state. When using the cleaning head on a textile floor covering is disadvantageous that the detergent is applied only superficially on the floor surface and is not mechanically incorporated into the textile covering. In order to achieve a sufficient cleaning effect, a relatively large amount of detergent must be used. After aspirating the detergent, a high residual moisture remains on the floor.

Aus EP 2 064 979 A1 ist ein Reinigungskopf bekannt, der in einer Walzenkammer eine Reinigungswalze aufweist. Vor und hinter einer bodenseitigen Öffnung der Walzenkammer ist jeweils eine Dichtungslippe vorgesehen, welche eine Zuströmung von Luft begrenzt. Die in die bodenseitige Öffnung eintretende Saugluft wird durch ein Gehäuse des Reinigungskopfes zu einem rückwärtig angeschlossenen Saugstutzen geleitet. Um abhängig von dem Bodenbelag eine ausreichende Durchströmung und Reinigungswirkung zu erzielen, ist ein Bypass vorgesehen, der mit einer bodenseitigen Bypassöffnung hinter der bodenseitigen Öffnung der Reinigungswalze mündet.Out EP 2 064 979 A1 For example, a cleaning head is known which has a cleaning roller in a roller chamber. Before and behind a bottom-side opening of the roller chamber a sealing lip is provided in each case, which limits an inflow of air. The entering into the bottom opening suction air is passed through a housing of the cleaning head to a back-connected suction. In order to achieve a sufficient flow and cleaning effect depending on the floor covering, a bypass is provided, which opens with a bottom-side bypass opening behind the bottom opening of the cleaning roller.

Aus US 2006/0288517 A1 ist ein Reinigungskopf bekannt, welcher eine Nass-Reinigungsfunktion aufweist. In einer Walzenkammer ist eine Reinigungswalze angeordnet, wobei an der Vorderseite des Reinigungskopfes Düsen für die Abgabe einer Reinigungsflüssigkeit vorgesehen sind. Die Reinigungsflüssigkeit wird vor den Reinigungskopf gesprüht und kann dann in einem gewissen Maße mit der übrigen Saugluft über eine bodenseitige Öffnung der Walzenkammer aufgenommen werden, wobei vor und hinter der Walzenkammer jeweils eine Dichtungslippe vorgesehen ist. Die Aufnahme von Flüssigkeit über die vergleichsweise große bodenseitige Öffnung der Walzenkammer ist verbesserungsbedürftig.Out US 2006/0288517 A1 a cleaning head is known, which has a wet cleaning function. In a roll chamber, a cleaning roller is arranged, wherein nozzles are provided for the discharge of a cleaning liquid at the front of the cleaning head. The cleaning liquid is sprayed in front of the cleaning head and can then be taken up to a certain extent with the remaining suction air via a bottom-side opening of the roller chamber, wherein in each case a sealing lip is provided in front of and behind the roller chamber. The inclusion of liquid over the comparatively large bottom-side opening of the roller chamber is in need of improvement.

Aus der Praxis sind auch Elektrobürstgeräte zur Nassreinigung von Bodenflächen bekannt, die sowohl auf Glattböden als auch auf textilen Bodenbelägen eingesetzt werden und eine Anordnung aus gegensinnig angetriebenen Bürstwalzen aufweisen. Durch die Bürstwalzen wird die Bodenfläche intensiv gebürstet und das auf die Bodenfläche aufgebrachte Reinigungsmittel einem Auffangbehälter zugeführt. Es wird nicht gesaugt. Das Reinigungsmittel muss daher in einer geringeren Dosierung eingesetzt werden als bei einem Sprühextraktionsverfahren. Die Restfeuchte des Bodenbelages ist nach der Anwendung daher geringer.From practice electro brushing devices for wet cleaning of floor surfaces are known, which are used both on smooth floors and on textile floor coverings and have an arrangement of oppositely driven brushing rollers. By the brush rollers, the bottom surface is brushed intensively and applied to the bottom surface cleaning agent supplied to a collecting container. It is not sucked. The detergent must therefore be used in a lower dosage than in a spray extraction process. The residual moisture of the floor covering is therefore lower after use.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Reinigungskopf für ein Reinigungsgerät zur Nassreinigung von Bodenflächen anzugeben, das die mit einem Reinigungsmittel benetzte Bodenfläche bürstet und das Reinigungsmittel wieder wirksam aufnimmt. Der Reinigungskopf soll universell und einfach handhabbar sein.Against this background, the invention has for its object to provide a cleaning head for a cleaning device for wet cleaning of floor surfaces, which brushes the wetted with a detergent floor surface and the cleaning agent effectively resumes. The cleaning head should be universal and easy to handle.

Gegenstand der Erfindung und Lösung dieser Aufgabe ist ein Reinigungskopf nach Anspruch 1.The object of the invention and solution of this problem is a cleaning head according to claim 1.

Erfindungsgemäß umfasst der Saugraum des Reinigungskopfes eine Walzenkammer, in der mindestens eine rotierend angetriebene Reinigungswalze angeordnet ist. Die Walzenkammer weist bodenseitig eine vorzugsweise rechteckförmige Öffnung auf, in welche ein Umfangsabschnitt der Reinigungswalze eintaucht. Die Saugöffnung zum Absaugen des Reinigungsmittels erstreckt sich entlang der bodenseitigen Öffnung der Walzenkammer und ist an ihrer von der Öffnung der Walzenkammer abgewandten Längsseite von einer Dichtungslippe begrenzt.According to the invention, the suction chamber of the cleaning head comprises a roller chamber, in which at least one rotationally driven cleaning roller is arranged. The roller chamber has on the bottom side a preferably rectangular opening into which a peripheral portion of the cleaning roller dips. The suction opening for sucking off the cleaning agent extends along the base-side opening of the roller chamber and is bounded on its side remote from the opening of the roller chamber longitudinal side of a sealing lip.

Die Reinigungswalze sorgt für das Verteilen des Reinigungsmittels und für einen intensiven mechanischen Kontakt mit dem Boden, beispielsweise einem Teppichflor oder einem Glattboden. Infolge der mechanischen Wirkung der Reinigungswalze auf der Bodenfläche kann das Reinigungsmittel sparsam dosiert werden. Mit der Absaugung ist jedoch auch ein verstärkter Reinigungsmitteleinsatz zur verbesserten Reinigung unschädlich. Durch den in die bodenseitige Öffnung der Walzenkammer eintretenden Luftstrom können ferner Schmutzpartikel aufgenommen und transportiert werden. Bei der Reinigung textiler Bodenflächen durchströmt der in die bodenseitige Öffnung der Walzenkammer eintretende Luftstrom zunächst den Faserflor und leistet dadurch auch einen Beitrag zur Trocknung der Bodenfläche. Die Hauptmenge des Reinigungsmittels wird jedoch durch die Saugöffnung abgesaugt, die erfindungsgemäß zu der bodenseitigen Öffnung der Walzenkammer benachbart ist und an ihrer von der Öffnung der Walzenkammer abgewandten Längsseite von einer Dichtungslippe begrenzt ist. An der Dichtungslippe sammelt sich Flüssigkeit, die auf dem Boden haftet und dann als Flüssigkeitsansammlung wirksam durch die Saugöffnung abgesaugt werden kann. Für die Anwendung auf einer textilen Bodenfläche ist die Dichtungslippe vorzugsweise als Schabkante ausgebildet, die steif ist oder nur eine geringe Flexibilität aufweist. Bei der Anwendung auf Glattböden sind flexible Abstreiflippen vorteilhaft, die sich an die Bodenfläche linienförmig anlegen und eine Abstreiffunktion aufweisen. Bei einem Reinigungskopf, der universell sowohl auf textilen Bodenflächen als auch auf Glattböden zum Einsatz kommen soll, sind halbsteife Gummilippen ein entsprechender Kompromiss.The cleaning roller provides for the distribution of the cleaning agent and for an intensive mechanical contact with the ground, for example a carpet pile or a smooth floor. Due to the mechanical action of the cleaning roller on the bottom surface, the detergent can be dispensed sparingly. With the suction, however, an increased detergent use for improved cleaning is harmless. By entering into the bottom opening of the roller chamber air flow dirt particles can also be recorded and transported. When cleaning textile bottom surfaces flows through the entering into the bottom opening of the roller chamber air flow first the batt and thereby makes a contribution to the drying of the bottom surface. However, the main amount of the cleaning agent is sucked through the suction opening, which is according to the invention adjacent to the bottom-side opening of the roller chamber and is limited at its side facing away from the opening of the roller chamber longitudinal side of a sealing lip. At the sealing lip liquid collects, which adheres to the floor and can then be effectively sucked as liquid accumulation through the suction opening. For use on a textile bottom surface, the sealing lip is preferably designed as a scraping edge, which is stiff or has only a slight flexibility. When used on smooth floors flexible wiper lips are advantageous, which create a line on the floor surface and have a Abstreiffunktion. In a cleaning head, which is to be used universally both on textile floor surfaces and on smooth floors, semi-rigid rubber lips are a compromise.

Die Öffnung der Walzenkammer ist an der Gehäuseunterseite von Flächenabschnitten begrenzt, die unterseitig vorstehende Saugmundkanten bilden. Der Abstand der Saugmundkanten von der zu reinigenden Bodenfläche wirkt sich auf die Saugeigenschaften beim Absaugen von Schmutzpartikeln aus und beeinflusst auch die Trocknungswirkung des in die bodenseitige Öffnung der Walzenkammer eintretenden Luftstromes. Mit zunehmender Reduzierung des Abstandes zwischen der Saugmundkante und der zu reinigenden Bodenfläche erhöht sich die Strömungsgeschwindigkeit der die Saugmundkanten umströmenden Luftströmung. Mit zunehmender Strömungsgeschwindigkeit können sowohl Tropfen als auch Schmutzpartikel aufgenommen und transportiert werden. Das Gehäuse des Reinigungskopfes weist vorzugsweise Rollen zur bodenseitigen Abstützung auf. Hierdurch kann ein definierter Abstand zwischen den Saugmundkanten und der zu reinigenden Bodenfläche eingerichtet werden. Im Rahmen der Erfindung liegt es dabei auch, dass die Rollen oder Bodengleitelemente höhenverstellbar sind und der Abstand der Saugmundkanten von der Bodenfläche in Abhängigkeit der Beschaffenheit der zu reinigenden Bodenfläche verändert werden kann.The opening of the roller chamber is bounded on the underside of housing surface portions which form the underside projecting Saugmundkanten. The distance of the suction mouth edges from the floor surface to be cleaned has an effect on the suction properties during suction of dirt particles and also influences the drying effect of the air flow entering the bottom opening of the roll chamber. With increasing reduction of the distance between the suction mouth edge and the floor surface to be cleaned, the flow velocity of the airflow flowing around the suction mouth edges increases. With increasing flow velocity, both drops and dirt particles can be absorbed and transported. The housing of the cleaning head preferably has rollers for bottom support. This allows a defined distance between the Saugmundkanten and the floor surface to be cleaned are set up. It is also within the scope of the invention that the rollers or floor sliding elements are height-adjustable and the distance of the suction mouth edges from the floor surface can be changed depending on the nature of the floor surface to be cleaned.

Die Saugmundkanten können an ein Gehäuseunterteil des Gehäuses angeformt oder fest mit dem Gehäuseunterteil verbunden sein. Eine in funktionsmäßiger Hinsicht besonders vorteilhafte Ausgestaltung der Erfindung sieht vor, dass die Walzenkammer aus einem im Gehäuse schwenkbar gelagerten Einsatz besteht, der abgewinkelte Flächenabschnitte mit Saugmundkanten aufweist. Durch eine schwenkbewegliche Lagerung der Walzenkammer passen sich die Saugmundkanten bei einer Bewegung des Reinigungskopfes über eine Bodenfläche an die Bodenfläche an. Eine leichte Schrägstellung des Reinigungskopfes, wenn dieser beispielsweise über einen hochflorigen Teppichbelag bewegt wird, kann durch eine schwenkbewegliche Lagerung der Walzenkammer ausgeglichen werden.The Saugmundkanten can be integrally formed on a lower housing part of the housing or fixed to the lower housing part. A functionally advantageous embodiment of the invention provides that the roller chamber consists of a pivotally mounted in the housing insert having angled surface sections with Saugmundkanten. By a pivotable mounting of the roller chamber, the Saugmundkanten adjust during a movement of the cleaning head via a bottom surface to the bottom surface. A slight inclination of the cleaning head, if this is moved over a high-pile carpet, for example, can be compensated by a pivotable mounting of the roller chamber.

Die Saugöffnung zum Absaugen des Reinigungsmittels grenzt vorzugsweise an eine Saugmundkante an. Bei einer Bewegung des Reinigungskopfes über eine textile Bodenfläche liegt die Saugmundkante auf dem Teppichflor auf, wobei die resultierende mechanische Bewegung des Teppichflors den Saugeffekt an der benachbarten verstärkt.The suction opening for sucking off the cleaning agent preferably adjoins a suction mouth edge. Upon movement of the cleaning head over a textile bottom surface, the suction mouth edge rests on the carpet pile, the resulting mechanical movement of the carpet pile reinforcing the suction effect on the adjacent one.

Die Einrichtung zur Abgabe des Reinigungsmittels weist mindestens eine Düse oder Auslassöffnung auf, die in Bezug auf eine Vorwärtsbewegung des Reinigungskopfes vor der bodenseitigen Öffnung der Walzenkammer oder innerhalb der Walzenkammer angeordnet sein kann. Vorzugsweise sind mehrere in einer Reihe angeordnete Auslassöffnungen oder Düsen vorgesehen, wobei die Sprühstrahlen des austretenden Reinigungsmittels auf die zu reinigende Bodenfläche oder die Reinigungswalze gerichtet sind.
