Description

Bodendüse für Hartböden Floor nozzle for hard floors
Die vorliegende Erfindung betrifft eine neuartige Bodendüse für Hartböden.The present invention relates to a novel floor nozzle for hard floors.
Aus der EP 447 627 A1 ist ein an einen Staubsauger anschließbares Zusatzgerät bekannt das aus einem Saugrohr, einem mit diesem verbindbaren Mundstück und einem am Saugrohr angeordneten Behälter für Reinigungsflüssigkeit besteht, bei welchem Zusatzgerät im Mundstückgehäuse eine flüssigkeitsleitend mit dem Behälter verbundene Verteilerleiste und ein dieser zugeordneter, bewegbar gelagerter Auftragskörper vorgesehen ist. Auf Grund der Anordnung des Behälters für Reinigungsflüssigkeit an dem Saugrohr des Staubsaugers ist das Arbeiten umständlich und bei einem Wechsel der Staubsaugerdüse zu einer reinen Saugdüse muss der gesonderte Behälter für Reinigungsflüssigkeit extra entfernt werden.From EP 447 627 A1 an attachable to a vacuum cleaner attachment is known which consists of a suction tube, a connectable with this mouthpiece and a suction tube arranged on the container for cleaning liquid, which accessory in Mundstückgehäuse a liquid-conducting connected to the container distribution strip and one of these , movably mounted applicator body is provided. Due to the arrangement of the container for cleaning liquid to the suction pipe of the vacuum cleaner working is cumbersome and when changing the vacuum cleaner nozzle to a clean suction nozzle, the separate container for cleaning fluid must be extra removed.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein gegen- über dem Stand der Technik verbesserte Anordnung für einen Behälter für Reinigungsflüssigkeit bereitzustellen.On this basis, the object of the present invention is to provide an arrangement, which is improved in comparison with the prior art, for a container for cleaning liquid.
Diese Aufgabe wird erfindungsgemäß durch eine Bodendüse für Hartböden gelöst, bei welche der Flüssigkeitstank an der Bodendüse angeordnet ist. Durch die Anordnung des Flüssigkeitstanks unmittelbar an der Bodendüse kann eine Feuchtreinigung durch die Bodendüse unabhängig von einem jeweiligen angeschlossenen Gerät durchgeführt werden. Eine Feuchtreinigung ist mit einer erfindungsgemäßen Bodendüse sogar selbst dann gewährleistet, wenn lediglich ein Führungsstiel eines Wischmops angeschlossen ist. Daneben ergibt sich der weitere Vorteil, dass keine gesonderten Verbindungsleitungen zwischen Bodendüse und einem externen Flüssigkeitstank erforderlich sind und somit der Betrieb der Bodendüse in einfacher Weise möglich ist, ohne dass Verbindungsleitungen an- oder abgesteckt werden müssen oder während der Benutzung störend herumhängen.This object is achieved by a floor nozzle for hard floors, in which the liquid tank is arranged on the floor nozzle. By arranging the liquid tank directly on the floor nozzle, a wet cleaning by the floor nozzle can be performed independently of a respective connected device. A wet cleaning is guaranteed even with a floor nozzle according to the invention even if only one guide stem of a mop is connected. In addition, there is the further advantage that no separate connection lines between the floor nozzle and an external liquid tank are required and thus the operation of the floor nozzle is possible in a simple manner without connecting cables must be connected or disconnected or hanging around disturbing during use.
Vorzugsweise ist der Flüssigkeitstank in die Bodendüse, insbesondere in eine Aufnahme- nische der Bodendüse integriert. Eine Aufnahme des Flüssigkeitstanks in eine Aufnahmenische hat den Vorteil, dass der Flüssigkeitstank nicht über die Kontur der Bodendüse heraussteht. Durch eine vollständige Integration des Flüssigkeitstanks in die Bodendüse wird über einen langen Zeitraum hinweg ausreichend Flüssigkeit zur Feuchthaltung des Wischmittels zur Verfügung gestellt. Dabei ist der Flüssigkeitstank platzsparend in der Bodendüse aufgenommen und die Bodendüse kann ohne Einbußen an Beweglichkeit benutzt werden.The liquid tank is preferably integrated in the floor nozzle, in particular in a receiving recess of the floor nozzle. A reception of the liquid tank in a receiving tables has the advantage that the liquid tank does not protrude beyond the contour of the floor nozzle. By a complete integration of the liquid tank into the floor nozzle For a long period of time sufficient liquid for moisturization of the wiper agent is provided. The liquid tank is added to save space in the floor nozzle and the floor nozzle can be used without sacrificing mobility.
In einer bevorzugten Ausgestaltung der Erfindung ist der Flüssigkeitstank an der Bodendüse abnehmbar gehalten. Zum Wiederauffüllen eines leeren Flüssigkeitstanks ist es sinnvoll den Flüssigkeitstank an der Bodendüse abnehmbar zu befestigen. Dies hat den Vorteil, dass ein leerer Flüssigkeitstank von der Bodendüse getrennt werden kann und als leichtes und kleines separates Teil beispielsweise zu einem Wasserhahn in einer Küche oder einem Bad eines Wohnbereichs gebracht werden kann, um den Flüssigkeitstank mit Wasser zu befüllen. Die Lösbarkeit des Flüssigkeitstanks erleichtert somit das Wiederbe- füllen für einen Benutzer.In a preferred embodiment of the invention, the liquid tank is detachably held on the floor nozzle. For refilling an empty liquid tank, it is useful to detachably attach the liquid tank to the floor nozzle. This has the advantage that an empty liquid tank can be separated from the floor nozzle and brought as a light and small separate part, for example to a faucet in a kitchen or a bathroom of a living area to fill the liquid tank with water. The solubility of the liquid tank thus facilitates refilling for a user.
Der Flüssigkeitstank kann einen Tragegriff aufweisen. Um einen entnommenen Flüssig- keitstank in bequemer Weise tragen zu können, kann ein Tragegriff an dem Flüssigkeitstank vorgesehen sein. Der Tragegriff kann als gesondertes Bauteil an dem Flüssigkeitstank befestigt sein. Optional kann der gesonderte Tragegriff schwenkbar an dem Flüssigkeitstank gelagert sein, so dass der Tragegriff für ein bequemes Tragen herausgeklappt werden kann und in einer in die Bodendüse eingesetzten Betriebsposition platzsparend an den Flüssigkeitstank angelegt werden kann. Alternativ zu einem Tragegriff als gesondertes Bauteil kann, wie in den folgenden Figuren dargestellt, der Tragegriff durch einen Griffabschnitt einer Wand des Flüssigkeitstanks gebildet werden. Der Griffabschnitt kann auch muldenförmig in eine Seitenwand des Flüssigkeitstanks integriert sein. Ist der Flüssigkeitstank als Teil einer Designblende ausgebildet, so kann der Tragegriff durch einen Abschnitt der Designblende gebildet werden.The liquid tank may have a carrying handle. In order to comfortably carry a withdrawn liquid tank, a carrying handle may be provided on the liquid tank. The carrying handle can be attached as a separate component to the liquid tank. Optionally, the separate carrying handle can be pivotally mounted on the liquid tank, so that the carrying handle can be folded out for convenient carrying and can be placed in a space used in the floor nozzle operating position to save space on the liquid tank. As an alternative to a carrying handle as a separate component, as shown in the following figures, the carrying handle can be formed by a grip portion of a wall of the liquid tank. The handle portion may also be trough-shaped integrated into a side wall of the liquid tank. If the liquid tank is formed as part of a design panel, then the carrying handle can be formed by a portion of the design panel.
Bevorzugt weist der Flüssigkeitstank ein aus transparentem Material hergestelltes Sichtfenster auf. Ist der Flüssigkeitstank mit einem Sichtfenster ausgestattet, so kann jederzeit durch optische Wahrnehmung der Füllstand des Flüssigkeitstanks festgestellt werden. Eine optische Wahrnehmbarkeit des Füllstandes hat den Vorteil, dass zu Beginn des gewünschten Reinigungsvorgangs festgestellt werden kann, ob noch ausreichend Flüssigkeit für die zu erfolgende Feuchtreinigung vorhanden ist, oder ob schon vor Beginn der Reinigung Flüssigkeit nachgefüllt werden muss. Dies hat den Vorteil, dass ein einmal be- gonnener Reinigungsvorgang nicht wegen eines leeren Flüssigkeitstanks unterbrochen werden muss. Folglich ist ein angenehmes Arbeiten in kurzer Zeit ermöglicht.The liquid tank preferably has a viewing window made of transparent material. If the liquid tank is equipped with a viewing window, the level of the liquid tank can be determined at any time by optical perception. An optical perceptibility of the filling level has the advantage that it can be determined at the beginning of the desired cleaning process whether there is still sufficient liquid for the wet cleaning to be carried out, or whether liquid must be refilled before the start of the cleaning. This has the advantage that once a gonnener cleaning process must not be interrupted because of an empty liquid tank. Consequently, a comfortable work in a short time is possible.
Alternativ oder ergänzend kann das Gehäuse des Flüssigkeitstanks aus transparentem Material hergestellt sein. Statt eines eingesetzten Fensters ist es alternativ auch möglich gleich den gesamten Flüssigkeitstank transparent auszubilden. Dies hat den Vorteil, dass eine optische Überprüfung von allen Seiten des Flüssigkeitstanks durchgeführt werden kann. Wird statt reinem Wasser eine andere Reinigungsflüssigkeit verwendet, so kann beispielsweise aufgrund eines farblichen Unterschiedes der Reinigungsflüssigkeit nicht nur der Füllstand, sondern auch die Art der derzeit vorhandenen Reinigungsflüssigkeit überprüft werden. Damit erhält der Benutzer eine noch bessere Kontrollmöglichkeit über den Zustand der Reinigungsvorrichtung.Alternatively or additionally, the housing of the liquid tank can be made of transparent material. Instead of an inserted window, it is alternatively also possible to make the entire liquid tank transparent. This has the advantage that a visual check can be performed from all sides of the liquid tank. If another cleaning liquid is used instead of pure water, it is possible, for example because of a difference in color of the cleaning liquid, to check not only the fill level but also the type of cleaning liquid currently present. This gives the user even better control over the condition of the cleaning device.
In allen Varianten kann der Flüssigkeitstank eine von einem Deckel verschließbare Einfüllöffnung aufweisen. Damit Flüssigkeit in den Flüssigkeitstank gefüllt werden kann ist eine Einfüllöffnung erforderlich. Damit während des Wischens aufgrund der Hin- und Herbewegungen keine Flüssigkeit über die Einfüllöffnung ungewollt austreten kann, ist die Einfüllöffnung durch einen Deckel verschließbar. Der Deckel kann ein einfacher Schraub- verschluss mit Gewinde sein. In einer bevorzugten Ausgestaltung ist der Deckel als gesondertes Bauteil, das stopfenartig auf die Einfüllöffnung aufgesetzt wird ausgebildet. Da- bei weist der Deckel eine Oberflächenkontur auf, die der Kontur der Bodendüse ange- passt ist.In all variants, the liquid tank may have a closure opening closable by a lid. So that liquid can be filled in the liquid tank a filling opening is required. So that no liquid can escape unintentionally via the filling opening during wiping due to the reciprocating movements, the filling opening can be closed by a lid. The cover can be a simple threaded screw cap. In a preferred embodiment, the lid is designed as a separate component, which is placed like a plug on the filling opening. The lid has a surface contour that matches the contour of the floor nozzle.
Vorzugsweise ist der Deckel mittels einer Rastverbindung oder eines Scharniers in einer die Einfüllöffnung verschließenden Position am Flüssigkeitstank gehalten. Wenn der De- ekel mittels eines Scharniers an dem Flüssigkeitstank gehalten ist, so kann der Deckel nicht verloren gehen. Eine Rastverbindung stellt sicher, dass der Deckel in seiner Schließposition festgehalten ist und keine Flüssigkeit aus dem Flüssigkeitstank ungewollt austreten kann.Preferably, the lid is held by means of a latching connection or a hinge in a position closing the filling opening on the liquid tank. When the lid is held by a hinge on the liquid tank, the lid can not be lost. A latching connection ensures that the lid is held in its closed position and no liquid can escape from the liquid tank unintentionally.
In einer vorteilhaften Ausgestaltung ist der Flüssigkeitstank mit einer abnehmbaren Designblende der Bodendüse einteilig ausgebildet.

Erfindungsgemäß ist der Flüssigkeitstank an oder in der Düse integriert und entnehmbar. Das Wasser zur Befeuchtung des Wischmittels wird in einem Tankbehälter, der an der Düse befestigt ist, bevorratet. Der Behälter ist vorzugsweise im Design der Düse integriert. Er kann aus einem transparenten Material, oder aus einem eingefärbten Material mit Sichtfenster, gebildet sein. Der Behälter kann zum Befüllen von der Düse entnommen werden. Am Behälter ist ein Griff zum leichten Transport integriert.According to the invention, the liquid tank is integrated on or in the nozzle and can be removed. The water for moistening the wiper is stored in a tank container attached to the nozzle. The container is preferably integrated in the design of the nozzle. It can be made of a transparent material or of a colored material with a viewing window. The container can be removed from the nozzle for filling. The container has a handle integrated for easy transport.
Der Wassertank wird mit einem Schraubverschluss oder mit einem Klappverschluss verschlossen.

Fig. 2 zeigt die Bodendüse nach Fig. 1 bei abgenommenen Flüssigkeitstank 1 1. In die Gehäuseschale 1 der Bodendüse ist eine Aufnahmenische 49 für den Flüssigkeitstank 1 1 vorgesehen. Die Aufnahmenische 49 ist in die Gehäuseschale 1 der Bodendüse einteilig eingeformt. Eine in die Bodendüse integrierte Flüssigkeitsversorgungseinrichtung 50 weist eine Anschlussverbindung 51 auf, die an eine Förderleitung 52 angeschlossen ist. Die Anschlussverbindung 51 weist einen hohlzylindrischen Dom 53 auf, an dessen oberen Ende ein Hohlnadelventil 54 angeordnet ist. Über eine am freien Ende des Hohlnadelventils 54 vorgesehene Öffnung wird aus dem Flüssigkeitstank 1 1 (Fig.3) Flüssigkeit eingesaugt, die durch den hohlzylindrischen Dom 53 in die Förderleitung 52 fließt. Der Unter- druck für das Ansaugen von Flüssigkeit aus dem Flüssigkeitstank 1 1 wird von einer Pumpe 100 erzeugt, die an die Förderleitung 52 angeschlossen ist.Fig. 2 shows the floor nozzle of Fig. 1 with removed liquid tank 1 1. In the housing shell 1 of the floor nozzle a receiving recess 49 for the liquid tank 1 1 is provided. The receiving recess 49 is integrally formed in the housing shell 1 of the floor nozzle. A liquid supply device 50 integrated into the floor nozzle has a connection connection 51, which is connected to a delivery line 52. The connection connection 51 has a hollow cylindrical dome 53, at the upper end of which a hollow needle valve 54 is arranged. Via an opening provided at the free end of the hollow needle valve 54, liquid is sucked from the liquid tank 11 (FIG. 3), which liquid flows through the hollow cylindrical dome 53 into the delivery line 52. The negative pressure for the suction of liquid from the liquid tank 1 1 is generated by a pump 100 which is connected to the delivery line 52.
Die Pumpe 100 ist als Membranpumpe ausgebildet und in einen Pumpenraum 55 in die Bodendüse eingesetzt. Der Pumpenraum 55 ist einteilig mit der Gehäuseschale 1 ausge- bildet. Die Pumpe 100 weist eine auslenkbare Membran 101 auf, die von einer in der Bodendüse beweglich gelagerten Kugel 102 aktivierbar ist. Auf Grund einer Auslenkung der Membran 101 wird eine definierte Menge an Flüssigkeit durch die Pumpe 100 gefördert. Die Kugel 102 liegt in eine Richtung frei rollend in einer Rinne 103 der Bodendüse. Die Rinne 103 ist einteilig an der Gehäuseschale 1 der Bodendüse angeformt. Die Krümmung der Rinne 103 ist an den Durchmesser der Kugel 102 angepasst, so dass die Kugel 102 in der Rinne 103 geführt ist und ein seitliches Ausweichen der Kugel 102 eingeschränkt ist. Die Rinne 103 erstreckt sich im wesentlichen in Schieberichtung der Bodendüse, so dass die Kugel 102 auf einer Bahn geführt ist, auf der sich die Kugel 102 in Schiebe- und Zugrichtung der Bodendüse innerhalb einer Strecke frei bewegen kann. Die Bewegung der Kugel 102 entlang der Strecke der Rinne 103 wird bei einer Vorwärts- bzw. Rückwärtsbewegung der Bodendüse in Schieberichtung bzw. Zugrichtung auf Grund der Massenträgheit der Kugel 102 induziert. Bei einer Rückwärtsbewegung der Bodendüse schlägt die Kugel 102 am vorderen Ende der Strecke der Rinne 103 an der Membran 101 der Pumpe 100 an, so dass die Membran 101 in Bewegung versetzt wird und aufgrund ihrer Auslenkbewegung eine definierte Menge Flüssigkeit aus der Förderleitung 52 zu einer Feuchtigkeitsübertragungseinrichtung 150 transportiert wird. Bei einer Vorwärtsbewegung der Bodendüse entfernt sich die Kugel 102 von der Membran 101 der Pumpe 100 und die Membran 101 kann in ihre Ausgangslage zurückkehren. Bei ihrer Bewegung in die Ausgangslage zurück wird in einer Pumpenkammer 1 14 der Pumpe 100 ein Unterdruck erzeugt, der eine Menge an Flüssigkeit aus einer Zuleitung 104 ansaugt.The pump 100 is designed as a diaphragm pump and inserted into a pump chamber 55 in the floor nozzle. The pump chamber 55 is formed in one piece with the housing shell 1. The pump 100 has a deflectable membrane 101 which can be activated by a ball 102 movably mounted in the floor nozzle. Due to a deflection of the membrane 101, a defined amount of liquid is pumped by the pump 100. The ball 102 is in a direction free rolling in a groove 103 of the floor nozzle. The channel 103 is integrally formed on the housing shell 1 of the floor nozzle. The curvature of the channel 103 is adapted to the diameter of the ball 102, so that the ball 102 is guided in the channel 103 and a lateral deflection of the ball 102 is limited. The channel 103 extends substantially in the sliding direction of the floor nozzle, so that the ball 102 is guided on a track on which the ball 102 in sliding and Pull direction of the floor nozzle can move freely within a stretch. The movement of the ball 102 along the distance of the channel 103 is induced in a forward or backward movement of the floor nozzle in the sliding direction or pulling direction due to the inertia of the ball 102. In a backward movement of the floor nozzle, the ball 102 at the front end of the distance of the channel 103 to the membrane 101 of the pump 100 so that the membrane 101 is set in motion and due to their deflection movement a defined amount of liquid from the feed line 52 to a moisture transfer device 150 is transported. With a forward movement of the floor nozzle, the ball 102 moves away from the diaphragm 101 of the pump 100 and the membrane 101 can return to its original position. During its movement back to the initial position, a negative pressure is generated in a pump chamber 14 of the pump 100, which draws in a quantity of liquid from a supply line 104.
In Figur 3 ist der Flüssigkeitstank 1 1 dargestellt. Der Flüssigkeitstank 1 1 weist eine Kammer 26 zum Speichern von Flüssigkeit auf. Die Kammer 26 ist im wesentliche quaderför- mig gestaltet und besitzt eine obere Deckenwand 27, eine untere Bodenwand 28 und vier Seitenwände 29. in der Deckenwand 27 ist die Einfüllöffnung 14 eingebracht. Die Einfüllöffnung 14 ist von dem Deckel 15 verschlossen. Zwischen Einfüllöffnung 14 und Deckel 15 ist eine Verschlussdichtung 30 zwischengefügt. Die Verschlussdichtung 30 ist beispielsweise am Deckel 15 befestigt. Der Deckel 15 ist mittels einer Rastfeder 12 an dem Flüssigkeitstank 1 1 lösbar befestigt. Ein Lösen des Deckels 15 von dem Flüssigkeitstank 1 1 erfolgt durch Schwenken der Rastfeder 12 seitlich nach außen von dem Deckel 15 weg. Ein manuelles Schwenken der Rastfeder 12 wird durch den Griffabschnitt 13 erleichtert, der an der Rastfeder 12 angeformt ist, so dass sich ein Betätigen des Griffabschnitts 13 auf die Rastfeder 12 überträgt und diese verschwenkt werden kann, um die Rastver- bindung zum Deckel 15 zu lösen.In Figure 3, the liquid tank 1 1 is shown. The liquid tank 1 1 has a chamber 26 for storing liquid. The chamber 26 is substantially parallelepiped-shaped and has an upper ceiling wall 27, a lower bottom wall 28 and four side walls 29 in the ceiling wall 27, the filling opening 14 is introduced. The filling opening 14 is closed by the lid 15. Between filling opening 14 and lid 15, a sealing seal 30 is interposed. The closure seal 30 is attached to the lid 15, for example. The lid 15 is releasably secured by means of a detent spring 12 to the liquid tank 1 1. A release of the lid 15 from the liquid tank 1 1 takes place by pivoting the detent spring 12 laterally outwardly from the lid 15. A manual pivoting of the detent spring 12 is facilitated by the handle portion 13 which is integrally formed on the detent spring 12, so that an actuation of the handle portion 13 transmits to the detent spring 12 and this can be pivoted to release the detent connection to the cover 15 ,

Das Dichtungsventil 34 verschießt die Abflussöffnung 33 bei aus der Bodendüse entnommenem Flüssigkeitstank 1 1. In der in die Bodendüse eingesetzten Position des Flüssigkeitstanks 1 1 dringt das Hohlnadelventil 54 der Gehäuseschale 1 in das Dichtungsventil 34 der Abflussöffnung 33 am Auslauf 32 ein, so dass der Auslauf 32 geöffnet ist und Flüssigkeit aus dem Flüssigkeitstank 1 1 über den Auslauf 32 und der Anschlussverbindung 51 an der Gehäuseschale 1 in die Förderlei- tung 52 der Flüssigkeitsversorgungseinrichtung 50 herausgefördert werden kann. Die Abflussöffnung 33 befindet sich nahe am oberen Ende der Höhe des Flüssigkeitstanks 1 1 , so dass bei entnommenem Flüssigkeitstanks 1 1 keine oder nur eine geringe Flüssigkeitssäule an der geschlossenen Abflussöffnung 33 ansteht. Damit während des Betriebs der Bodendüse möglichst der gesamte Flüssigkeitsinhalt aus dem Flüssigkeitstanks 1 1 abge- pumpt werden kann, ist die Abflussöffnung 33 mit einer Saugleitung 35 verbunden, deren freie Ansaugöffnung 36 nahe an die untere Bodenwand 28 des Flüssigkeitstanks 1 1 reicht.In the lower bottom wall 28 of the chamber 26, a bush-shaped recess 31 is formed, which is adapted in shape and size to the dome 53 of the liquid supply device 50 in the housing shell 1 such that the sleeve-shaped recess 31 in the installed position of the liquid tank. 1 1 in the floor nozzle precisely over the dome 53 inverts. A spout 32 corresponding to the hollow needle valve 54 of the housing shell 1 is equipped with a discharge opening 33. At the discharge opening 33, a sealing valve 34 is attached. The sealing valve 34 shoots the In the inserted into the floor nozzle position of the liquid tank 1 1 penetrates the hollow needle valve 54 of the housing shell 1 in the seal valve 34 of the discharge opening 33 at the outlet 32, so that the outlet 32 is open and liquid from the liquid tank 1 1 via the outlet 32 and the connection connection 51 on the housing shell 1 in the conveying line 52 of the liquid supply device 50 can be conveyed out. The drain opening 33 is located near the upper end of the height of the liquid tank 1 1, so that when removed liquid tank 1 1 no or only a small liquid column is present at the closed drain opening 33. So that the entire liquid content can be pumped out of the liquid tank 1 1 during operation of the floor nozzle, the discharge opening 33 is connected to a suction line 35 whose free suction opening 36 extends close to the lower bottom wall 28 of the liquid tank 11.
Der Flüssigkeitstank 1 1 ist in eine Designblende 37 der Bodendüse integriert. Die Design- blende 37 ist schalenartig gestaltet und in Form und Größe an die Gestalt der Bodendüse angepasst. Die Designblende 37 erstreckt sich dabei über annähernd die gesamte Breite der Bodendüse.
