Auch aus den Druckschriften
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbesserte Anordnung für einen Behälter für Reinigungsflüssigkeit bereitzustellen.On this basis, the present invention has the object to provide a comparison with the prior art improved arrangement 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.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.
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.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 Aufnahmenische 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 in the floor nozzle sufficient liquid for moisturizing the wiper is provided over a long period of time. 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 Wiederbefüllen 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 weist einen Tragegriff auf. Um einen entnommenen Flüssigkeitstank in bequemer Weise tragen zu können, ist ein Tragegriff an dem Flüssigkeitstank vorgesehen.The liquid tank has a carrying handle. In order to be able to comfortably carry a withdrawn liquid tank, a carrying handle is provided on the liquid tank.
Erfindungsgemäß ist der Flüssigkeitstank als Teil einer Designblende ausgebildet und der Tragegriff wird durch einen Abschnitt der Designblende gebildet.According to the invention, the liquid tank is formed as part of a design panel and the carrying handle is 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 begonnener 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 perception of the level has the advantage that at the beginning of the desired Cleaning process can be determined whether there is still sufficient liquid for the to be carried out wet cleaning, or whether liquid must be refilled before the start of cleaning. This has the advantage of being started once Cleaning process does not have to 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 Schraubverschluss mit Gewinde sein. In einer bevorzugten Ausgestaltung ist der Deckel als gesondertes Bauteil, das stopfenartig auf die Einfüllöffnung aufgesetzt wird ausgebildet. Dabei weist der Deckel eine Oberflächenkontur auf, die der Kontur der Bodendüse angepasst 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 lid 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. In this case, the lid has a surface contour which is adapted to 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 Deckel 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. If the lid is held by a hinge on the liquid tank, so 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. Idealer Weise kann das Gehäuse des Flüssigkeitstanks in seiner Form an die Kontur der Bodendüse angepasst sein. Dadurch integriert sich der Flüssigkeitstank in besonders vorteilhafter Weise in die Kontur der Bodendüse. Es entstehen keine Störkonturen, die den optischen Eindruck von Designmerkmalen stören könnten. Dies verleiht der Bodendüse zunächst für den Verkauf und später für die Benutzung ein ansprechendes Äußeres.In an advantageous embodiment, the liquid tank is formed integrally with a removable design panel of the floor nozzle. Ideally, the housing of the liquid tank can be adapted in its shape to the contour of the floor nozzle. As a result, the liquid tank is integrated in a particularly advantageous manner in the contour of the floor nozzle. There are no interference contours that could disturb the visual impression of design features. This gives the floor nozzle first for sale and later for use a pleasing appearance.
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. Der Anschluss zum Wasserkreislauf in der Düse ist im Behälter integriert und wird mit einem Ventil verschlossen, das bei der Montage des Behälters öffnet.The water tank is closed with a screw cap or with a snap closure. The connection to the water circuit in the nozzle is integrated in the container and is closed by a valve which opens when the container is mounted.
Die Vorteile eines solchen Tanks liegen in der Kundenfreundlichkeit des leichten Entnehmens und Befüllen des Wassertanks.The advantages of such a tank lie in the customer friendliness of the easy removal and filling of the water tank.
Die erfindungsgemäße Düse eignet sich insbesondere für handelsübliche Bodenstaubsauger. Sie kann jedoch auch ohne Bodenstaubsauger verwendet werden, da der Tank vorteilhaft in der Düse integriert ist.The nozzle according to the invention is particularly suitable for commercial vacuum cleaner. However, it can also be used without a vacuum cleaner, as the tank is advantageously integrated in the nozzle.

Die Schnapp-Rastverbindung 20 ist nicht starr, sondern weist einen Freiheitsgrad auf, so dass der Aufnahmestutzen 17 bezüglich der Gelenkskugel 19 um eine koaxial zum Aufnahmestutzen 17 verlaufende Rotationsachse 21 drehbar gelagert ist. Zur Realisierung dieser Drehbarkeit um die Rotationsachse 21 weist der Aufnahmestutzen 17 mehrere über seinen Umfang verteilte nach innen gerichtete Rasthaken 22 auf, die in eine nach außen gerichtete umlaufende Rastringnut 23 an einem Anschluss 24 der Gelenkskugel 19 eingreifen.The floor nozzle is connected via a connection joint 16 with a receiving
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 ausgebildet. 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 114 der Pumpe 100 ein Unterdruck erzeugt, der eine Menge an Flüssigkeit aus einer Zuleitung 104 ansaugt.The
In
In die untere Bodenwand 28 der Kammer 26 ist ein buchsenförmiger Rücksprung 31 eingeformt, der in Form und Größe an den Dom 53 der Flüssigkeitsversorgungseinrichtung 50 in der Gehäuseschale 1 derart angepasst ist, dass sich der buchsenförmiger Rücksprung 31 in der eingebauten Position des Flüssigkeitstanks 11 in der Bodendüse passgenau über den Dom 53 stülpt. Eine zum Hohlnadelventil 54 der Gehäuseschale 1 korrespondierender Auslauf 32 ist mit einer Abflussöffnung 33 ausgestattet. An der Abflussöffnung 33 ist ein Dichtungsventil 34 angebracht. Das Dichtungsventil 34 verschießt die Abflussöffnung 33 bei aus der Bodendüse entnommenem Flüssigkeitstank 11. In der in die Bodendüse eingesetzten Position des Flüssigkeitstanks 11 dringt das Hohinadelventil 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 11 über den Auslauf 32 und der Anschlussverbindung 51 an der Gehäuseschale 1 in die Förderleitung 52 der Flüssigkeitsversorgungseinrichtung 50 herausgefördert werden kann. Die Abflussöffnung 33 befindet sich nahe am oberen Ende der Höhe des Flüssigkeitstanks 11, so dass bei entnommenem Flüssigkeitstanks 11 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 11 abgepumpt werden kann, ist die Abflussöffnung 33 mit einer Saugleitung 35 verbunden, deren freie Ansaugöffnung 36 nahe an die untere Bodenwand 28 des Flüssigkeitstanks 11 reicht.In the
Der Flüssigkeitstank 11 ist in eine Designblende 37 der Bodendüse integriert. Die Designblende 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. Die Designblende 37 weist einen Kragenausschnitt 38 auf, der als einseitig offene Freisparung mit bogenförmiger Kontur aus der Designblende 37 ausgeschnitten ist. Über den Kragenausschnitt 38 kann in der abgedeckten Lage der Designblende 37 auf der Bodendüse die Kontur der Gelenkskugel 19 des Anschlussgelenks 16 aus der Düsenebene hervortreten. Über den Kragenausschnitt 38 mit einseitig offener Freisparung und bogenförmiger Kontur wird in der Designblende 37 eine taillierte Einschnürung geschaffen, die einen Tragegriff 39 für den Flüssigkeitstank 11 bildet. An einem dem Flüssigkeitstank 11 gegenüberliegenden Ende der Designblende 37 ist ein Fensterausschnitt 40 für ein Sichtfenster 41 eingebracht. Der Fensterausschnitt 40 ist als einseitig offene Freisparung in der Designblende 37 ausgeschnitten. Das eingesetzte Sichtfenster 41 ermöglicht in der eingebauten Lage der Designblende 37 in der Bodendüse einen Einblick auf die dahinterliegende Pumpe 100 bzw. die Kugel 102.The
