- the hard surface cleaning device has a suction nozzle on which at least one Abziehlfl is arranged, and can be moved in the manner of a manual Breabziehers along the hard surface, so that accumulates liquid in the region of the suction opening.
- the suction opening is in fluid communication with a suction unit, with the aid of which the suction opening can be acted upon by a suction flow, so that a mixture of liquid and air can be sucked from the suction opening.
- a deposition chamber is positioned between the suction nozzle and the suction unit.
- a separation device for separating liquid from the liquid-air mixture is arranged in the deposition chamber.
- the separated liquid passes from the deposition chamber into a dirty liquid tank which is releasably held in a tank receiving compartment of the hard surface cleaning apparatus is.
- the suction unit has a suction turbine, which is surrounded by a turbine housing.
- the turbine housing is connected via a Turbineneinlassteil with the deposition chamber, so that the suction turbine can suck air from the deposition chamber.
- Such Hartviditessetti are from the EP 2 237 711 B1 and the EP 2 230 980 B1 as well as from the EP 2 227 126 B1 known. They have proven themselves in practice. With their help windows in particular can be cleaned within a short time. The user can guide the portable hard surface cleaning device with the at least one Abziehlippe on the window pane and remove liquid located on the window pane.
- the operation of the known Hartviditesstechnik is associated with a certain operating noise. It is desirable to reduce the noise of such hard surface cleaning equipment.
- Object of the present invention is therefore to develop a hard surface cleaning device of the type mentioned in such a way that it has a lower noise.
- a hard surface cleaning device of the generic type according to the invention that the turbine housing is connected via a turbine outlet with the tank receiving compartment, wherein a wall of the tank receiving compartment and the dirty liquid tank limit an air outlet, in which opens the turbine outlet and via which sucked by the suction turbine Air can be discharged to the environment.
- the idea flows in that the noise of the hard surface cleaning device can be reduced in that the exhaust air of the suction turbine is not directly delivered to the environment of the hard surface cleaning device but first an air outlet space is supplied, which is between a wall of the tank receiving compartment and the in the tank receiving compartment used dirty fluid tank is located. outgoing From the suction turbine thus the exhaust air is first supplied to the air outlet space, and from the air outlet then the exhaust air can be discharged to the environment.
- the portable hard surface cleaning device according to the invention is characterized by a relatively low noise.
- the portable hard surface cleaning device according to the invention has the advantage that it can be produced more cheaply, because unlike known Hartviditess expertn molded into a housing of Hartviditess réelles vents omitted, rather, the exhaust air of the suction turbine can be delivered to an air outlet space extending between a wall the tank receiving compartment and the dirty liquid tank extends.
- the portable hard surface cleaning device has a base housing, in which the turbine housing is arranged.
- the basic housing forms the tank receiving compartment.
- the basic housing can advantageously be formed by two housing halves.
- the portable hard surface cleaning device has a separation unit, in which the deposition chamber is arranged.
- the separation unit is releasably connected to the suction nozzle.
- the separation unit is releasably connected to a housing of the hard surface cleaning device receiving the turbine housing.
- the dirty liquid tank inserted into the tank receiving compartment forms a deflecting element with the aid of which the exhaust air flowing into the air outlet space from the suction turbine via the turbine outlet part is deflected.
- the dirty liquid tank thus forces a deflection of the exhaust air, and this in turn leads to a further noise reduction.
- the air outlet space forms a flow labyrinth, which is bounded on the one hand by the wall of the tank receiving compartment and on the other hand by the dirty fluid tank.
- the provision of a flow labyrinth makes it possible to keep the noise of the portable hard surface cleaning device particularly low.
- the flow labyrinth may, for example, extend along a rear region of the contaminant tank as well as along longitudinal sides of the contaminant tank remote from one another. The exhaust air of the suction turbine thus undergoes several changes of direction on its way from the turbine outlet part to the surroundings of the hard surface cleaning device.
- the dirty liquid tank is made of an elastically deformable plastic material, because thereby the dirty liquid tank inserted into the tank receiving compartment forms an acoustic insulating element under the effect of which the noise development can be kept particularly low.

- the upper housing part of the turbine housing is bell-shaped and covers the suction turbine, wherein the turbine inlet line integrally connects to the upper housing part.
- Particularly low flow losses can be achieved in an advantageous embodiment of the invention in that the turbine inlet line is designed arcuate.
- This allows a fluidically optimized design, so that a high efficiency can be generated.
- the high efficiency has the advantage that even with the use of a suction unit with relatively low power an effective suction flow can be achieved, so that a mixture of liquid and air can be reliably sucked from the suction port.
- the lower power of the suction unit in turn makes it possible to use a relatively small drive motor. As a result, not only the noise development of the hard surface cleaning device according to the invention can be kept low but also its energy consumption.

- the motor housing can be formed in combination with the lower housing part of the turbine housing of two half-shells, to which the preferably integrally connected to the turbine inlet line housing upper part of the turbine housing can be placed.
- the housing upper part of the turbine housing together with the turbine inlet line forms a one-piece plastic molded part.
- the latter is in an advantageous embodiment with the two half-shells, which form the motor housing and the lower housing part of the turbine housing, detachably connectable, in particular latched or screwed.

The suction unit has a suction turbine, which is surrounded by a turbine housing. The turbine housing is connected via a Turbineneinlassteil with the deposition chamber, so that the suction turbine can suck air from the deposition chamber.

Aufgabe der vorliegenden Erfindung ist es deshalb, ein Hartflächenreinigungsgerät der eingangs genannten Art derart weiterzubilden, dass es eine geringere Geräuschentwicklung aufweist.Object of the present invention is therefore to develop a hard surface cleaning device of the type mentioned in such a way that it has a lower noise.
Diese Aufgabe wird bei einem Hartflächenreinigungsgerät der gattungsgemäßen Art erfindungsgemäß dadurch gelöst, dass das Turbinengehäuse über ein Turbinenauslassteil mit dem Tankaufnahmefach verbunden ist, wobei eine Wandung des Tankaufnahmefachs und der Schmutzflüssigkeitstank einen Luftauslassraum begrenzen, in den das Turbinenauslassteil einmündet und über den die von der Saugturbine angesaugte Luft an die Umgebung abgebbar ist.This object is achieved in a hard surface cleaning device of the generic type according to the invention that the turbine housing is connected via a turbine outlet with the tank receiving compartment, wherein a wall of the tank receiving compartment and the dirty liquid tank limit an air outlet, in which opens the turbine outlet and via which sucked by the suction turbine Air can be discharged to the environment.
In die Erfindung fließt der Gedanke mit ein, dass die Geräuschentwicklung des Hartflächenreinigungsgeräts dadurch reduziert werden kann, dass die Abluft der Saugturbine nicht unmittelbar an die Umgebung des Hartflächenreinigungsgeräts abgegeben wird sondern zunächst einem Luftauslassraum zugeführt wird, der sich zwischen einer Wandung des Tankaufnahmefachs und dem in das Tankaufnahmefach eingesetzten Schmutzflüssigkeitstank befindet. Ausgehend von der Saugturbine wird somit die Abluft zunächst dem Luftauslassraum zugeführt, und vom Luftauslassraum kann dann die Abluft an die Umgebung abgegeben werden.In the invention, the idea flows in that the noise of the hard surface cleaning device can be reduced in that the exhaust air of the suction turbine is not directly delivered to the environment of the hard surface cleaning device but first an air outlet space is supplied, which is between a wall of the tank receiving compartment and the in the tank receiving compartment used dirty fluid tank is located. outgoing From the suction turbine thus the exhaust air is first supplied to the air outlet space, and from the air outlet then the exhaust air can be discharged to the environment.
Das erfindungsgemäße tragbare Hartflächenreinigungsgerät zeichnet sich durch eine verhältnismäßig geringe Geräuschentwicklung aus. Darüber hinaus hat das erfindungsgemäße tragbare Hartflächenreinigungsgerät den Vorteil, dass es kostengünstiger hergestellt werden kann, denn im Unterschied zu bekannten Hartflächenreinigungsgeräten können in ein Gehäuse des Hartflächenreinigungsgeräts eingeformte Lüftungsschlitze entfallen, vielmehr kann die Abluft der Saugturbine an einen Luftauslassraum abgegeben werden, der sich zwischen einer Wandung des Tankaufnahmefaches und dem Schmutzflüssigkeitstank erstreckt.The portable hard surface cleaning device according to the invention is characterized by a relatively low noise. In addition, the portable hard surface cleaning device according to the invention has the advantage that it can be produced more cheaply, because unlike known Hartflächenreinigungsgeräten molded into a housing of Hartflächenreinigungsgeräts vents omitted, rather, the exhaust air of the suction turbine can be delivered to an air outlet space extending between a wall the tank receiving compartment and the dirty liquid tank extends.
Es kann vorgesehen sein, dass das tragbare Hartflächenreinigungsgerät ein Grundgehäuse aufweist, in dem das Turbinengehäuse angeordnet ist.It can be provided that the portable hard surface cleaning device has a base housing, in which the turbine housing is arranged.
Günstig ist es, wenn das Grundgehäuse das Tankaufnahmefach ausbildet.It is favorable if the basic housing forms the tank receiving compartment.
Das Grundgehäuse kann vorteilhafterweise von zwei Gehäusehalbschalen gebildet sein.The basic housing can advantageously be formed by two housing halves.
Bei einer vorteilhaften Ausführungsform weist das tragbare Hartflächenreinigungsgerät eine Abscheideeinheit auf, in der die Abscheidekammer angeordnet ist.In an advantageous embodiment, the portable hard surface cleaning device has a separation unit, in which the deposition chamber is arranged.
Von Vorteil ist es, wenn die Abscheideeinheit mit der Saugdüse lösbar verbunden ist.It is advantageous if the separation unit is releasably connected to the suction nozzle.
Besonders günstig ist es, wenn die Abscheideeinheit mit einem das Turbinengehäuse aufnehmenden Grundgehäuse des Hartflächenreinigungsgeräts lösbar verbunden ist.It is particularly advantageous if the separation unit is releasably connected to a housing of the hard surface cleaning device receiving the turbine housing.
Bevorzugt bildet der in das Tankaufnahmefach eingesetzte Schmutzflüssigkeitstank ein Umlenkelement aus, mit dessen Hilfe die von der Saugturbine über das Turbinenauslassteil in den Luftauslassraum einströmende Abluft umgelenkt wird. Der Schmutzflüssigkeitstank erzwingt somit eine Umlenkung der Abluft, und dies wiederum führt zu einer weiteren Geräuschreduzierung.Preferably, the dirty liquid tank inserted into the tank receiving compartment forms a deflecting element with the aid of which the exhaust air flowing into the air outlet space from the suction turbine via the turbine outlet part is deflected. The dirty liquid tank thus forces a deflection of the exhaust air, and this in turn leads to a further noise reduction.
Von Vorteil ist es, wenn der Luftauslassraum ein Strömungslabyrinth ausbildet, das einerseits von der Wandung des Tankaufnahmefachs und andererseits vom Schmutzflüssigkeitstank begrenzt wird. Die Bereitstellung eines Strömungslabyrinths ermöglicht es, die Geräuschentwicklung des tragbaren Hartflächenreinigungsgeräts besonders gering zu halten. Das Strömungslabyrinth kann sich beispielsweise entlang eines rückwärtigen Bereichs des Schmutzflüssigkeitstanks sowie entlang einander abgewandten Längsseiten des Schmutzflüssigkeitstanks erstrecken. Die Abluft der Saugturbine erfährt dadurch mehrere Richtungsänderungen auf ihrem Weg vom Turbinenauslassteil zur Umgebung des Hartflächenreinigungsgeräts.It is advantageous if the air outlet space forms a flow labyrinth, which is bounded on the one hand by the wall of the tank receiving compartment and on the other hand by the dirty fluid tank. The provision of a flow labyrinth makes it possible to keep the noise of the portable hard surface cleaning device particularly low. The flow labyrinth may, for example, extend along a rear region of the contaminant tank as well as along longitudinal sides of the contaminant tank remote from one another. The exhaust air of the suction turbine thus undergoes several changes of direction on its way from the turbine outlet part to the surroundings of the hard surface cleaning device.
Besonders günstig ist es, wenn der Schmutzflüssigkeitstank aus einem elastisch verformbaren Kunststoffmaterial hergestellt ist, denn dadurch bildet der in das Tankaufnahmefach eingesetzte Schmutzflüssigkeitstank ein akustisches Dämmelement aus, unter dessen Wirkung die Geräuschentwicklung besonders gering gehalten werden kann. Die Abluft der Saugturbine trifft innerhalb des Tankaufnahmefachs auf den Schmutzflüssigkeitstank, der sich unter der Wirkung der Abluft geringfügig verformen kann und dadurch der Abluft Strömungsenergie entnimmt und auf diese Weise die Geräuschentwicklung verringert.It is particularly favorable if the dirty liquid tank is made of an elastically deformable plastic material, because thereby the dirty liquid tank inserted into the tank receiving compartment forms an acoustic insulating element under the effect of which the noise development can be kept particularly low. The exhaust air from the suction turbine impinges within the tank receiving compartment on the dirty liquid tank, which can deform slightly under the action of the exhaust air and thereby the flow of exhaust air takes energy and thus reduces the noise.
Bei einer vorteilhaften Ausführungsform der Erfindung ist das Turbineneinlassteil als Turbineneinlassleitung ausgestaltet, die sich vom Turbinengehäuse bis zur Abscheidekammer erstreckt. Dies erlaubt es, den Strömungsweg der Luft zu optimieren und dadurch die Geräuschentwicklung zu verringern.In an advantageous embodiment of the invention, the turbine inlet part is configured as a turbine inlet line, which extends from the turbine housing to the deposition chamber. This makes it possible to optimize the flow path of the air and thereby reduce the noise.
Die Turbineneinlassleitung ist vorteilhafterweise einteilig ausgebildet, wobei sie unmittelbar in die Abscheidekammer einmündet und mit ihrem der Abscheidekammer abgewandten Ende unmittelbar an das Turbinengehäuse der Saugturbine angeschlossen ist.The turbine inlet line is advantageously formed in one piece, wherein it opens directly into the deposition chamber and is connected with its end facing away from the deposition chamber directly to the turbine housing of the suction turbine.
Die Turbineneinlassleitung kann beispielsweise in Form eines Schlauchstückes ausgebildet sein, das sich von der Abscheidekammer bis zum Turbinengehäuse erstreckt.For example, the turbine inlet conduit may be in the form of a length of tubing extending from the deposition chamber to the turbine housing.
Alternativ kann vorgesehen sein, dass die Turbineneinlassleitung als Rohrstück ausgebildet ist, das sich von der Abscheidekammer bis zum Turbinengehäuse erstreckt.Alternatively, it may be provided that the turbine inlet line is designed as a pipe section which extends from the separation chamber to the turbine housing.
Günstigerweise ist die Turbineneinlassleitung an das Turbinengehäuse angeformt. Dies ermöglicht es, die Turbineneinlassleitung zusammen mit dem Turbinengehäuse in kostengünstiger Weise herzustellen.Conveniently, the turbine inlet line is integrally formed on the turbine housing. This makes it possible to manufacture the turbine inlet pipe together with the turbine housing in a cost effective manner.
Es kann beispielsweise vorgesehen sein, dass das Turbinengehäuse ein Gehäuseoberteil und ein Gehäuseunterteil aufweist, die die Saugturbine umgeben, wobei das Gehäuseoberteil und die Turbineneinlassleitung ein einteiliges Kunststoffformteil ausbilden. Eine derartige Ausgestaltung ermöglicht eine kostengünstige Herstellung und eine einfache Montage des Hartflächenreinigungsgeräts.It can be provided, for example, that the turbine housing has an upper housing part and a lower housing part, which surround the suction turbine, wherein the upper housing part and the turbine inlet line form a one-piece plastic molded part. Such a configuration allows a cost-effective production and easy installation of the hard surface cleaning device.
Günstig ist es, wenn das Gehäuseoberteil des Turbinengehäuses mit dem Gehäuseunterteil des Turbinengehäuses werkzeuglos verbindbar ist.It is favorable if the upper housing part of the turbine housing can be connected without tools to the lower housing part of the turbine housing.
Insbesondere kann vorgesehen sein, dass das Gehäuseoberteil mit dem Gehäuseunterteil verrastbar ist.In particular, it can be provided that the upper housing part can be latched to the lower housing part.
Von besonderem Vorteil ist es, wenn sich das Gehäuseoberteil in Richtung der Turbineneinlassleitung kontinuierlich verjüngt. Dies ermöglicht es, Strömungsverluste der aus der Abscheidekammer über die Turbineneinlassleitung zur Saugturbine angesaugten Luft gering zu halten.It is particularly advantageous if the housing upper part continuously tapers in the direction of the turbine inlet line. This allows flow losses to keep the air sucked from the deposition chamber via the turbine inlet line to the suction turbine low.
Es kann beispielsweise vorgesehen sein, dass das Gehäuseoberteil des Turbinengehäuses glockenförmig ausgebildet ist und die Saugturbine überdeckt, wobei sich die Turbineneinlassleitung einstückig an das Gehäuseoberteil anschließt.It can be provided, for example, that the upper housing part of the turbine housing is bell-shaped and covers the suction turbine, wherein the turbine inlet line integrally connects to the upper housing part.
Besonders geringe Strömungsverluste können bei einer vorteilhaften Ausführungsform der Erfindung dadurch erzielt werden, dass die Turbineneinlassleitung bogenförmig ausgestaltet ist. Dies ermöglicht eine strömungstechnisch optimierte Bauform, so dass ein hoher Wirkungsgrad erzeugt werden kann. Der hohe Wirkungsgrad hat den Vorteil, dass selbst bei Einsatz eines Saugaggregates mit verhältnismäßig geringer Leistung eine wirkungsvolle Saugströmung erzielt werden kann, so dass ein Gemisch aus Flüssigkeit und Luft zuverlässig von der Saugöffnung abgesaugt werden kann. Die geringere Leistung des Saugaggregats wiederum ermöglicht es, einen verhältnismäßig kleinen Antriebsmotor zu verwenden. Dadurch kann nicht nur die Geräuschentwicklung des erfindungsgemäßen Hartflächenreinigungsgeräts gering gehalten werden sondern auch dessen Energieverbrauch.Particularly low flow losses can be achieved in an advantageous embodiment of the invention in that the turbine inlet line is designed arcuate. This allows a fluidically optimized design, so that a high efficiency can be generated. The high efficiency has the advantage that even with the use of a suction unit with relatively low power an effective suction flow can be achieved, so that a mixture of liquid and air can be reliably sucked from the suction port. The lower power of the suction unit in turn makes it possible to use a relatively small drive motor. As a result, not only the noise development of the hard surface cleaning device according to the invention can be kept low but also its energy consumption.
Von Vorteil ist es, wenn das tragbare Hartflächenreinigungsgerät wiederaufladbare Batterien umfasst. Dies ermöglicht es, das tragbare Haftflächenreinigungsgerät auch dann zum Einsatz zu bringen, wenn kein Netzanschluss zur Verfügung steht. Darüber hinaus kann bei Einsatz einer wiederaufladbaren Batterie ein Netzkabel entfallen, so dass es einfach ist, das tragbare Hartflächenreinigungsgerät an einer Hartfläche entlang zu führen.It is advantageous if the portable hard surface cleaning device comprises rechargeable batteries. This makes it possible to use the portable surface cleaning device even when no power supply is available. In addition, when using a rechargeable battery, a power cord can be omitted, so that it is easy to guide the portable hard surface cleaning device along a hard surface.
Die Laufzeit der mindestens einen wiederaufladbaren Batterie wird verlängert, sofern das Saugaggregat mit geringem Energieverbrauch betrieben werden kann. Dies wiederum wird ermöglicht durch die strömungsoptimierte Ausgestaltung insbesondere der Turbineneinlassleitung.The life of the at least one rechargeable battery is extended, provided that the suction unit can be operated with low energy consumption. This in turn is made possible by the flow-optimized design, in particular of the turbine inlet line.
Das Gehäuseunterteil des Turbinengehäuses ist bei einer vorteilhaften Ausgestaltung an ein Motorgehäuse angeformt, das einen Antriebsmotor der Saugturbine und mindestens eine wiederaufladbare Batterie und günstigerweise auch eine Batterieüberwachungselektronik umgibt.The lower housing part of the turbine housing is formed in an advantageous embodiment of a motor housing surrounding a drive motor of the suction turbine and at least one rechargeable battery and conveniently also a battery monitoring electronics.
Von Vorteil ist es, wenn im Motorgehäuse eine Steuereinrichtung des tragbaren Hartflächenreinigungsgeräts angeordnet ist.It is advantageous if a control device of the portable hard surface cleaning device is arranged in the motor housing.
Günstigerweise bildet das Turbinengehäuse in Kombination mit der Turbineneinlassleitung und dem Motorgehäuse eine vormontierbare Baueinheit aus, die mit Ausnahme einer Schalteinrichtung und einer die Schalteinrichtung mit der Steuereinrichtung elektrisch verbindenden Verbindungsleitung sämtliche elektrischen Bauteile des Hartflächenreinigungsgeräts aufnimmt und diese gegen Spritzwasser schützt.The turbine housing in combination with the turbine inlet line and the motor housing expediently forms a preassemblable structural unit which, with the exception of a switching device and a connecting line electrically connecting the switching device to the control device, receives all the electrical components of the hard surface cleaning device and protects them against spray water.
Das Motorgehäuse kann in Kombination mit dem unteren Gehäuseteil des Turbinengehäuses von zwei Halbschalen gebildet sein, auf die das bevorzugt einstückig mit der Turbineneinlassleitung verbundene Gehäuseoberteil des Turbinengehäuses aufsetzbar ist.The motor housing can be formed in combination with the lower housing part of the turbine housing of two half-shells, to which the preferably integrally connected to the turbine inlet line housing upper part of the turbine housing can be placed.
Wie bereits erwähnt, ist es von Vorteil, wenn das Gehäuseoberteil des Turbinengehäuses zusammen mit der Turbineneinlassleitung ein einteiliges Kunststoffformteil ausbildet. Letzteres ist bei einer vorteilhaften Ausführungsform mit den beiden Halbschalen, die das Motorgehäuse und das Gehäuseunterteil des Turbinengehäuses ausbilden, lösbar verbindbar, insbesondere verrastbar oder verschraubbar.As already mentioned, it is advantageous if the housing upper part of the turbine housing together with the turbine inlet line forms a one-piece plastic molded part. The latter is in an advantageous embodiment with the two half-shells, which form the motor housing and the lower housing part of the turbine housing, detachably connectable, in particular latched or screwed.
Die Turbineneinlassleitung durchgreift bei einer vorteilhaften Ausgestaltung der Erfindung einen Griff des Hartflächenreinigungsgeräts. Dies erlaubt eine besonders kompakte Bauform des Hartflächenreinigungsgeräts. Der Griff kann vom Benutzer umgriffen werden.In an advantageous embodiment of the invention, the turbine inlet line penetrates a handle of the hard surface cleaning device. This allows a particularly compact design of the hard surface cleaning device. The handle can be grasped by the user.
Bevorzugt bildet ein Grundgehäuse des Hartflächenreinigungsgeräts den Griff aus.Preferably, a base housing of the hard surface cleaning device forms the handle.
Wie bereits erwähnt, steht die Saugturbine über das Turbinenauslassteil mit dem Luftauslassraum in Strömungsverbindung. Günstig ist es, wenn das Turbinenauslassteil eine Turbinenauslassleitung ausbildet, die in den Luftauslassraum eintaucht.As already mentioned, the suction turbine is in fluid communication with the air outlet space via the turbine outlet part. It is favorable if the turbine outlet part forms a turbine outlet line which dips into the air outlet space.
Es kann beispielsweise vorgesehen sein, dass die Turbinenauslassleitung in Form eines Rohrstücks ausgebildet ist, das sich einstückig an das Turbinengehäuse der Saugturbine anschließt.It can be provided, for example, that the turbine outlet line is designed in the form of a tubular piece which integrally connects to the turbine housing of the suction turbine.
Der Schmutzflüssigkeitstank weist bei einer vorteilhaften Ausführungsform der Erfindung eine Tankwand auf, die gegenüber dem Mündungsbereich der Auslassleitung und im Abstand zu diesem angeordnet ist. Die Abluft der Saugturbine durchströmt somit die Turbinenauslassleitung und trifft dann auf die im Abstand zum Mündungsbereich der Turbinenauslassleitung angeordnete Tankwand, an der sie umgelenkt wird.In an advantageous embodiment of the invention, the dirty liquid tank has a tank wall, which is arranged opposite the mouth region of the outlet line and at a distance therefrom. The exhaust air from the suction turbine thus flows through the turbine outlet line and then strikes the tank wall arranged at a distance from the mouth region of the turbine outlet line, at which point it is deflected.
Vorzugsweise erfährt die Abluft an der Tankwand eine Umlenkung um mindestens 90°.Preferably, the exhaust air at the tank wall undergoes a deflection by at least 90 °.
Die Abluft der Saugturbine wird bei einer besonders bevorzugten Ausgestaltung der Erfindung am Schmutzflüssigkeitstank in mindestens zwei Teilströmungen aufgeteilt, die den Schmutzflüssigkeitstank auf einander abgewandten Seiten umströmen. Die Strömungsrate der aus dem Luftauslassraum herausströmenden Teilströmungen der Abluft kann dadurch verhältnismäßig gering gehalten werden. Dies hat eine weitere Verminderung der Geräuschentwicklung des Hartflächenreinigungsgeräts zur Folge.The exhaust air of the suction turbine is divided in a particularly preferred embodiment of the invention at the dirty liquid tank in at least two partial flows, which flow around the dirty liquid tank on sides facing away from each other. The flow rate of the flowing out of the Luftauslassraum partial flows of the exhaust air can be kept relatively low. This results in a further reduction of the noise of the hard surface cleaning device result.
Von besonderem Vorteil ist es, wenn der Luftauslassraum einen rückwärtigen Raumbereich aufweist, in den das Turbinenauslassteil einmündet und der hinter dem Schmutzflüssigkeitstank angeordnet ist, sowie zwei seitliche Raumbereiche, die sich an den rückwärtigen Raumbereich anschließen und sich spaltförmig auf zwei einander abgewandten Seiten des Schmutzflüssigkeitstanks erstrecken.It is particularly advantageous if the air outlet space has a rearward region in which the turbine outlet part opens and which is arranged behind the dirty liquid tank, and two lateral spatial regions, which adjoin the rear space area and extend in a gap shape on two opposite sides of the dirty fluid tank.
Der Schmutzflüssigkeitstank weist bei einer vorteilhaften Ausgestaltung der Erfindung einen unteren Tankabschnitt auf, der bei vertikaler Ausrichtung des Hartflächenreinigungsgeräts in vertikaler Richtung in einen den Schmutzflüssigkeitstank untergreifenden unteren Abschnitt des Tankaufnahmefachs einsetzbar ist. Dies erleichtert die Handhabung des Schmutzflüssigkeitstanks beim Einsetzen und beim Entnehmen aus dem Tankaufnahmefach.In an advantageous embodiment of the invention, the dirty liquid tank has a lower tank section which, in the vertical orientation of the hard surface cleaning device, can be inserted in a vertical direction into a lower section of the tank receiving compartment engaging under the dirty liquid tank. This facilitates the handling of the dirty fluid tank during insertion and removal from the tank receiving compartment.
Günstigerweise umfasst der Schmutzflüssigkeitstank einen oberen Tankabschnitt, der auf einander abgewandten Außenseiten Rastelemente aufweist, die mit korrespondierenden Rastelementen des Tankaufnahmefachs eine Rastverbindung ausbilden. Bei einer derartigen Ausgestaltung ist der Schmutzflüssigkeitstank mit dem Tankaufnahmefach lösbar verrastbar. Hierbei befinden sich an einander abgewandten Außenseiten des Schmutzflüssigkeitstanks erste Rastelemente, die mit korrespondierenden zweiten Rastelementen des Tankaufnahmefachs zusammenwirken.Conveniently, the dirty liquid tank comprises an upper tank section which has locking elements on opposite outer sides which form a latching connection with corresponding latching elements of the tank receiving compartment. In such an embodiment, the dirty liquid tank with the tank receiving compartment is releasably latched. Here are located on opposite outer sides of the dirty liquid tank first locking elements, which cooperate with corresponding second locking elements of the tank receiving compartment.
Günstigerweise sind die am Schmutzflüssigkeitstank angeordneten ersten Rastelemente von den zweiten Rastelementen des Tankaufnahmefachs hintergreifbar. Beispielsweise kann vorgesehen sein, dass der Schmutzflüssigkeitstank an einander abgewandten Seiten Rücksprünge aufweist, die von Rastvorsprüngen des Tankaufnahmefachs hintergreifbar sind. Die Rücksprünge bilden somit erste Rastelemente aus und die Vorsprünge bilden zweite Rastelemente aus, die mit den ersten Rastelementen eine lösbare Rastverbindung ausbilden.Conveniently, the first latching elements arranged on the dirty liquid tank can be engaged behind by the second latching elements of the tank receiving compartment. For example, it can be provided that the dirty liquid tank has recesses on opposite sides which can be engaged behind by latching projections of the tank receiving compartment. The recesses thus form first latching elements and the projections form second latching elements, which form a releasable latching connection with the first latching elements.
Zwischen dem oberen Tankabschnitt und dem unteren Tankabschnitt weist der Schmutzflüssigkeitstank bei einer bevorzugten Ausgestaltung des erfindungsgemäßen tragbaren Hartflächenreinigungsgeräts einen mittleren Tankabschnitt auf, der den Luftauslassraum tankseitig begrenzt. Bei einer derartigen Ausgestaltung erstreckt sich der Luftauslassraum über den mittleren Tankabschnitt des Schmutzflüssigkeitstanks.Between the upper tank section and the lower tank section, the dirty liquid tank in a preferred embodiment of the portable hard surface cleaning device according to the invention has a central tank section which delimits the air outlet space on the tank side. In such an embodiment the air outlet space extends over the middle tank section of the dirty fluid tank.
Zwischen dem mittleren Tankabschnitt und dem oberen Tankabschnitt bildet der Schmutzflüssigkeitstank bei einer vorteilhaften Ausgestaltung eine Strömungsbegrenzung aus, beispielsweise eine Rippe, die den mittleren Tankabschnitt auf seiner Oberseite begrenzt.Between the central tank section and the upper tank section of the dirty liquid tank forms in an advantageous embodiment of a flow restriction, for example, a rib which limits the central tank section on its upper side.
Die Begrenzung des mittleren Tankabschnitts auf seiner Unterseite wird bei einer bevorzugten Ausgestaltung der Erfindung dadurch erzielt, dass der Schmutzflüssigkeitstank zwischen dem mittleren Tankabschnitt und dem unteren Tankabschnitt eine Anlagefläche ausbildet, die an einer Stufe des Tankaufnahmefachs anliegt.The limitation of the central tank portion on its underside is achieved in a preferred embodiment of the invention in that the dirty liquid tank between the central tank portion and the lower tank portion forms a contact surface, which bears against a step of the tank receiving compartment.
Es kann auch vorgesehen sein, dass der Schmutzflüssigkeitstank zwischen dem mittleren Tankabschnitt und dem unteren Tankabschnitt eine Strömungsbegrenzung ausbildet, beispielsweise eine Rippe.It can also be provided that the dirty liquid tank forms a flow restriction between the central tank section and the lower tank section, for example a rib.
Das erfindungsgemäße Hartflächenreinigungsgerät bildet vorteilhafterweise ein tragbares Fensterputzgerät aus.The hard surface cleaning device according to the invention advantageously forms a portable window cleaning device.

Oberhalb der Prallwand 52 taucht in die Abscheidekammer 50 ein Aufnahmeschacht 54 der Abscheideeinheit 46 ein, und unterhalb der Prallwand 52 ist in der Abscheidekammer 50 ein Rohrstück 56 angeordnet, das von der Prallwand 52 überdeckt wird. Das Rohrstück 56 erstreckt sich bis zu einer Luftauslassöffnung 58 der Abscheidekammer 50. Im Abstand zur Luftauslassöffnung 58 weist die Abscheidekammer 50 eine Flüssigkeitsauslassöffnung 60 auf, die vom Entlüftungsrohr 36 der Befüllungseinrichtung 30 durchgriffen wird. Ein Endabschnitt des Entlüftungsrohrs 36 taucht in die Abscheidekammer 50 ein, und das Einfüllrohr 34 schließt sich an die Flüssigkeitsauslassöffnung 60 an.The

Mit einem der Abscheideeinheit 46 zugewandten Endabschnitt durchgreift der Saugkanal 64 den Aufnahmeschacht 54 und taucht in die Abscheidekammer 50 ein. Innerhalb der Abscheidekammer 50 bildet der Saugkanal 64 Haltestege 72 aus, an deren freien Ende eine Prallplatte 74 gehalten ist, die im Abstand zur Prallwand 52 innerhalb der Abscheidekammer 50 positioniert ist. Zwischen den Haltestegen 72 weist der Saugkanal 64 eine Vielzahl von Auslassöffnungen auf.

Die angesaugte Luft kann von der Saugturbine 18 über ein Turbinenauslassteil abgegeben werden, das in der dargestellten Ausführungsform als Turbinenauslassleitung 92 ausgebildet ist.

Der Übergang vom mittleren Tankabschnitt 122 zum oberen Tankabschnitt 124 erfolgt über eine horizontal ausgerichtete Rippe 128 des Schmutzflüssigkeitstanks 28.The transition from the
Innerhalb des oberen Tankabschnitts 124 bildet der Schmutzflüssigkeitstank 28 einen vorstehenden Bereich 130 aus, der von der ersten Durchbrechung 100 des Tankaufnahmefachs 26 aufgenommen wird. Oberhalb des vorstehenden Bereichs 130 weist der Schmutzflüssigkeitstank 28 auf einander abgewandten Außenseiten jeweils einen Rücksprung 132 auf. Wenn der Schmutzflüssigkeitstank 28 in das Tankaufnahmefach 26 eingesetzt wurde, werden die Rücksprünge 132 jeweils von einem Rastvorsprung 134 des Grundgehäuses 14 hintergriffen. Die Rastvorsprünge 134 werden von Halteflügeln 136, 138 gebildet, die oberhalb der Ausnehmung 100 an die freien Kanten 140, 142 der ersten Seitenwand 96 und der zweiten Seitenwand 98 angeformt sind. Die beiden Halteflügel 136, 138 nehmen somit den oberen Tankabschnitt 124 im Bereich der Rücksprünge 132 zwischen sich auf.Within the
Die Schrägfläche 102 der Bodenwand 94 des Tankaufnahmefachs 26 weist eine zweite Durchbrechung 144 auf, die von der Turbinenauslassleitung 92 durchgriffen wird.The
Wie insbesondere aus
Wie bereits erwähnt, kann das Hartflächenreinigungsgerät 10 nach Art eines manuellen Fensterabziehers zum Reinigen einer Hartfläche, insbesondere einer Fensterscheibe oder einer Glastür, an der Hartfläche entlanggeführt werden, wobei mittels der Abziehlippen 68 und 70 an der Hartfläche befindliche Flüssigkeit der Saugöffnung 66 zugeführt werden kann. Über den Saugkanal 64 kann die Flüssigkeit zusammen mit Luft von der Saugöffnung 66 abgesaugt und der Abscheidekammer 50 zugeführt werden. Die Abscheidekammer 50 kann hierzu vom Saugaggregat 16 über die Turbineneinlassleitung 78 mit Unterdruck beaufschlagt werden. Das Gemisch aus Flüssigkeit und Luft durchströmt den Saugkanal 64 und trifft innerhalb der Abscheidekammer 50 zunächst auf die Prallplatte 74, an der sich ein Teil der mitgeführten Flüssigkeit abscheidet. Anschließend trifft das Flüssigkeits-Luft-Gemisch auf die Prallwand 52, an der sich die restliche mitgeführte Flüssigkeit abscheidet, wohingegen die angesaugte Luft die Prallwand 52 umströmt und über das Rohrstück 56 und die Turbineneinlassleitung 68 zur Saugturbine 18 gelangt. Von der Saugturbine 18 wird die angesaugte Luft über die Turbinenauslassleitung 92 dem Luftauslassraum 146 zugeführt, wobei sie auf die Schrägfläche 152 des Schmutzflüssigkeitstanks 28 trifft und von dieser um 90° umgelenkt wird. Über die seitlichen Raumbereiche 150 des Luftauslassraums 146 kann dann die angesaugte Luft an die Umgebung des tragbaren Hartflächenreinigungsgeräts abgegeben werden.As already mentioned, the hard
Die in der Abscheidekammer 50 abgeschiedene Flüssigkeit kann über die Flüssigkeitsauslassöffnung 60 und das sich daran anschließende Einfüllrohr 34 in den Schmutzflüssigkeitstank 28 gelangen. Bei Bedarf kann der Schmutzflüssigkeitstank 28 entleert werden. Hierbei hat der Benutzer die Möglichkeit, den Stöpsel 40 aus der Ablauföffnung 38 herauszuziehen, so dass die im Schmutzflüssigkeitstank 28 befindliche Flüssigkeit über die Ablauflippe 38 ausgegossen werden kann. Der Stöpsel 40 ist mittels der Haltelasche 42 unverlierbar am Schmutzflüssigkeitstank 28 gehalten.The separated in the
Alternativ kann der Benutzer den Schmutzflüssigkeitstank 28 dem Tankaufnahmefach 26 entnehmen. Hierbei kann er den vorstehenden Bereich 130 des Schmutzflüssigkeitstanks 28 durch die erste Durchbrechung 100 der Bodenwand 94 nach vorne drücken, so dass die Rastvorsprünge 134 des Tankaufnahmefachs die korrespondierenden Rücksprünge 132 freigeben und der Schmutzflüssigkeitstank 28 anschließend dem Tankaufnahmefach 26 entnommen werden kann. Der Benutzer hat dann die Möglichkeit, die Befüllungseinrichtung 36 dem Schmutzflüssigkeitstank 28 zu entnehmen und den Schmutzflüssigkeitstank 28 zu entleeren. Anschließend kann der Benutzer die Befüllungseinrichtung 30 wieder in den Schmutzflüssigkeitstank 28 einsetzen und den Schmutzflüssigkeitstank 28 im Tankaufnahmefach 26 positionieren.Alternatively, the user may remove the
Das erfindungsgemäße tragbare Hartflächenreinigungsgerät zeichnet sich durch eine geringe Geräuschentwicklung aus. Dies wird vor allem dadurch erzielt, dass die von der Saugturbine 28 angesaugte Luft nicht unmittelbar an die Umgebung des Hartflächenreinigungsgeräts 10 abgegeben wird. Vielmehr durchströmt die von der Saugturbine 18 abgegebene Luft ein Strömungslabyrinth, das vom Luftauslassraum 146 gebildet wird.The portable hard surface cleaning device according to the invention is characterized by a low noise level. This is achieved above all by the fact that the air sucked in by the
Das Hartflächenreinigungsgerät 10 zeichnet sich darüber hinaus durch eine strömungsoptimierte Bauform aus. Die Strömungsoptimierung wird insbesondere durch die bogenförmige Ausgestaltung der Turbineneinlassleitung 78 und dem sich ausgehend von der Turbineneinlassleitung 78 kontinuierlich erweiternden Gehäuseoberteil 80 des Turbinengehäuses 82 erzielt. Die strömungsoptimierte Bauform hat zur Folge, dass das Saugaggregat 16 einen hohen Wirkungsgrad aufweist, so dass ein Antriebsmotor 20 mit verhältnismäßig geringer elektrischer Leistung zum Einsatz kommen kann. Dies wiederum hat eine weitere Verminderung der Geräuschentwicklung des Hartflächenreinigungsgeräts 10 zur Folge. Darüber hinaus hat der Einsatz eines Antriebsmotors 20 mit verhältnismäßig geringer elektrischer Leistung den Vorteil, dass das Hartflächenreinigungsgerät 10 einen geringen Energieverbrauch aufweist, so dass die wiederaufladbare Batterie 22 eine lange Lebensdauer hat.The hard
