Dies kann allerdings im Laufe der Zeit zu einer Ermüdung der Bedienungsperson führen, da das Führen des Gerätes entlang der Fensterscheibe einen gewissen Kraftaufwand erfordert.Hard surface suction devices comprising a suction device with a suction nozzle, a separation unit and a suction unit, and further comprising a dirty liquid tank and a handle, the separation unit having a separation chamber in which at least one separation element is arranged and which comprises a suction inlet, a liquid outlet and an air outlet, wherein the suction inlet with the suction nozzle, the liquid outlet with the dirty liquid tank and the air outlet with the suction unit in flow connection are from the publications WO 2009/086891 A1 , WO 2009/086892 A1 and WO 2009/086893 A1 known. They have proven themselves in practice. With their help, window panes in particular can be cleaned effectively. To do this, the user guides the hard surface suction device along the window pane while holding the device by the handle. Over time, however, this can lead to fatigue for the operator, since guiding the device along the window pane requires a certain amount of force.

Ein Hartflächenabsauggerät mit den Merkmalen des Oberbegriffes von Patentanspruch 1 ist aus der Veröffentlichung WO 2008/065313 A2 bekannt.A hard surface suction device with the features of the preamble of claim 1 is from the publication WO 2008/065313 A2 known.

Aufgabe der vorliegenden Erfindung ist es, ein Hartflächenabsauggerät der eingangs genannten Art derart weiterzubilden, dass es eine einfache Handhabung aufweist, wobei es von einer Bedienungsperson mit geringerem Kraftaufwand an einer Hartfläche entlanggeführt werden kann.The object of the present invention is to further develop a hard surface suction device of the type mentioned at the outset in such a way that it is easy to handle, it being possible for an operator to move it along a hard surface with less effort.

Diese Aufgabe wird durch ein Hartflächenabsauggerät mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved by a hard surface suction device with the features of patent claim 1.

Wie bereits erwähnt, umfasst die Absaugeinrichtung die Saugdüse, die Abscheideeinheit und das Saugaggregat des Hartflächenabsauggerätes. Der Handgriff ist bezogen auf eine aufrechte Stellung des Hartflächenabsauggerätes unterhalb der Absaugeinrichtung angeordnet. Es hat sich gezeigt, dass dadurch der Kraftaufwand bei der Handhabung des Hartflächenabsauggerätes reduziert werden kann. Die Bedienungsperson kann das Hartflächenabsauggerät unterhalb der Absaugeinrichtung am Handgriff ergreifen. Mit ihrer Hand kann somit die Bedienungsperson die Absaugeinrichtung unmittelbar abstützen. Dadurch können beim Schwenken des Hartflächenabsauggerätes auftretende Kippmomente gering gehalten werden.As already mentioned, the suction device comprises the suction nozzle, the separation unit and the suction unit of the hard surface suction device. The handle is arranged below the suction device in relation to an upright position of the hard surface suction device. It has been shown that this can reduce the effort required to handle the hard surface suction device. The operator can use the hard surface suction device Take hold of the handle below the suction device. The operator can thus directly support the suction device with their hand. As a result, tilting moments that occur when the hard surface suction device is pivoted can be kept low.

Gemäß der Erfindung umgibt der Handgriff zumindest einen Teil des Schmutzflüssigkeitstanks. Der Schmutzflüssigkeitstank kann vollständig vom Handgriff umgeben sein. Es kann allerdings auch vorgesehen sein, dass der Schmutzflüssigkeitstank einen ersten Tankbereich aufweist, der vom Handgriff umgeben ist, sowie einen zweiten Tankbereich, der aus dem Handgriff herausragt. Hierbei ist es von Vorteil, wenn der aus dem Handgriff herausragende Bereich des Schmutzflüssigkeitstanks bezogen auf eine aufrechte Stellung des Hartflächenabsauggerätes unterhalb des Handgriffs angeordnet ist.According to the invention, the handle surrounds at least a part of the dirty liquid tank. The dirty liquid tank can be completely surrounded by the handle. It can, however, also be provided that the dirty liquid tank has a first tank area which is surrounded by the handle and a second tank area which protrudes from the handle. It is advantageous here if the area of the dirty liquid tank protruding from the handle is arranged below the handle in relation to an upright position of the hard surface suction device.

Bevorzugt ist ergänzend zum Handgriff auch der Schmutzflüssigkeitstank bezogen auf eine aufrechte Stellung des Hartflächenabsauggeräts unterhalb der Absaugeinrichtung angeordnet. Im Laufe des Betriebs füllt sich der Schmutzflüssigkeitstank zunehmend mit Flüssigkeit, die in der Abscheidekammer aus dem von der Hartfläche abgesaugten Flüssigkeits-Luftgemisch abgeschieden wurde und über den Flüssigkeitsauslass in den Schmutzflüssigkeitstank gelangt. Mit zunehmendem Füllstand des Schmutzflüssigkeitstanks erhöht sich dessen Gewicht, so dass sich der Schwerpunkt des Hartflächenabsauggerätes zunehmend verlagert. Durch die Positionierung sowohl des Schmutzflüssigkeitstanks als auch des Handgriffs unterhalb der Absaugeinrichtung kann auch bei zunehmender Schwerpunktsverlagerung das beim Entlangführen des Hartflächenabsauggerätes an der Hartfläche auftretende Kippmoment und damit der von der Bedienungsperson aufzuwendende Kraftaufwand gering gehalten werden.In addition to the handle, the dirty liquid tank is preferably also arranged below the suction device in relation to an upright position of the hard surface suction device. In the course of operation, the dirty liquid tank is increasingly filled with liquid which was separated in the separation chamber from the liquid-air mixture sucked off the hard surface and which reaches the dirty liquid tank via the liquid outlet. As the level of the dirty liquid tank increases, its weight increases, so that the focus of the hard surface suction device is increasingly shifted. By positioning both the dirty liquid tank and the handle below the suction device, the tilting moment that occurs when the hard surface suction device is moved along the hard surface and thus the effort required by the operator can be kept low, even with increasing shift in the center of gravity.

Der Schmutzflüssigkeitstank ist bevorzugt unmittelbar am Flüssigkeitsauslass der Abscheidekammer angeordnet.The dirty liquid tank is preferably arranged directly at the liquid outlet of the separation chamber.

Von Vorteil ist es, wenn die Absaugeinrichtung eine Anlagefläche aufweist, von der der Handgriff absteht. An die Anlagefläche kann die Bedienungsperson beim Ergreifen des Handgriffs Daumen und Zeigefinger und/oder einen Teil ihres Handrückens anlegen. Dadurch kann der zur Handhabung des Hartflächenabsauggerätes erforderliche Kraftaufwand weiter verringert werden.It is advantageous if the suction device has a contact surface from which the handle protrudes. When gripping the handle, the operator can place his thumb and forefinger and / or part of the back of his hand on the contact surface. As a result, the effort required to handle the hard surface suction device can be further reduced.

Das Saugaggregat weist eine Saugturbine auf, die von einem Elektromotor um eine Turbinenachse in Drehung versetzt werden kann, um eine Saugströmung auszubilden. Der Handgriff ist bevorzugt länglich ausgebildet und weist eine Längsachse auf. Von Vorteil ist es, wenn die Längsachse des Handgriffs in einem Winkel zur Turbinenachse ausgerichtet ist.The suction unit has a suction turbine which can be set in rotation by an electric motor about a turbine axis in order to form a suction flow. The handle is preferably elongated and has a longitudinal axis. It is advantageous if the longitudinal axis of the handle is oriented at an angle to the turbine axis.

Günstigerweise schneidet die Längsachse des Handgriffs die Turbinenachse im Bereich der Abscheideeinheit oder im Bereich des Saugaggregates.The longitudinal axis of the handle advantageously intersects the turbine axis in the area of the separation unit or in the area of the suction unit.

Bei einer bevorzugten Ausgestaltung des erfindungsgemäßen Hartflächenabsauggerätes ist der Handgriff bezogen auf eine aufrechte Stellung des Hartflächenabsauggerätes unterhalb des Saugaggregates angeordnet. Der Handgriff nimmt somit unmittelbar das Gewicht des Saugaggregates auf.In a preferred embodiment of the hard surface suction device according to the invention, the handle is arranged below the suction unit in relation to an upright position of the hard surface suction device. The handle thus directly absorbs the weight of the suction unit.

Alternativ kann vorgesehen sein, dass der Handgriff bezogen auf eine aufrechte Stellung des Hartflächenabsauggerätes unterhalb der Abscheideeinheit angeordnet ist.Alternatively, it can be provided that the handle is arranged below the separation unit in relation to an upright position of the hard surface suction device.

Es kann vorgesehen sein, dass das Saugaggregat von einer Bedienungsperson untergreifbar ist. Dies ermöglicht es der Bedienungsperson, das Saugaggregat unmittelbar mit der Hand abzustützen.It can be provided that the suction unit can be grasped from under by an operator. This enables the operator to directly support the suction unit by hand.

Günstig ist es, wenn das Hartflächenabsauggerät zumindest eine wiederaufladbare Batterie aufweist. Dadurch kann das Hartflächenabsauggerät unabhängig vom Zugang zu einer Steckdose betrieben werden. Dies erleichtert die Handhabung des Hartflächenabsauggerätes.It is favorable if the hard surface suction device has at least one rechargeable battery. This means that the hard surface suction device can be operated independently of access to a socket. This facilitates the handling of the hard surface suction device.

Von Vorteil ist es, wenn zumindest eine wiederaufladbare Batterie im Handgriff positioniert ist. Der Handgriff bildet bei einer derartigen Ausgestaltung einen Aufnahmeraum, in den mindestens eine wiederaufladbare Batterie eingesetzt werden kann. Günstigerweise ist die mindestens eine wiederaufladbare Batterie im Handgriff austauschbar gehalten.It is advantageous if at least one rechargeable battery is positioned in the handle. In such a configuration, the handle forms a receiving space in which at least one rechargeable battery can be inserted. The at least one rechargeable battery is expediently kept exchangeable in the handle.

Es kann vorgesehen sein, dass die mindestens eine wiederaufladbare Batterie mittels eines externen Ladegeräts geladen werden kann.It can be provided that the at least one rechargeable battery can be charged by means of an external charger.

Zusätzlich zu einer wiederaufladbaren Batterie weist das erfindungsgemäße Hartflächenabsauggerät bei einer bevorzugten Ausgestaltung der Erfindung eine Ladeelektronik auf zum Aufladen der wiederaufladbaren Batterie, wobei die Ladeelektronik an eine externe Spannungsversorgungseinrichtung anschließbar ist, beispielsweise an ein Ladegerät.In addition to a rechargeable battery, the hard surface suction device according to the invention in a preferred embodiment of the invention has charging electronics for charging the rechargeable battery, the charging electronics being connectable to an external power supply device, for example a charger.

Der Schmutzflüssigkeitstank definiert bei einer vorteilhaften Ausführungsform eine Stellfläche zum Abstellen des Hartflächenabsauggerätes auf einem Untergrund.In an advantageous embodiment, the dirty liquid tank defines a footprint for placing the hard surface suction device on a surface.

Günstig ist es, wenn das Saugaggregat einen Turbineneinlass aufweist, der am Luftauslass der Abscheidekammer angeordnet ist. Der Strömungsweg zwischen der Abscheidekammer und dem Saugaggregat kann dadurch besonders kurz ausgebildet sein. Dies erhöht den Wirkungsgrad des Hartflächenabsauggerätes und hat zur Folge, dass das Saugaggregat mit einem kleineren Elektromotor ausgestattet werden kann, so dass das Gewicht und der Energieverbrauch des Hartflächenabsauggerätes reduziert werden können. Das geringere Gewicht erleichtert die Handhabung des Hartflächenabsauggerätes.It is favorable if the suction unit has a turbine inlet which is arranged at the air outlet of the separation chamber. The flow path between the separation chamber and the suction unit can therefore be designed to be particularly short. This increases the efficiency of the hard surface suction device and has the consequence that the suction unit can be equipped with a smaller electric motor so that the weight and energy consumption of the hard surface suction device can be reduced. The lower weight facilitates the handling of the hard surface suction device.

Günstigerweise ist am Turbineneinlass ein Saugrohr angeordnet, das in die Abscheidekammer eintaucht. In Strömungsrichtung des in die Abscheidekammer einströmenden Flüssigkeits-Luftgemisches kann das freie Ende des Saugrohrs im Abstand zu einem Abscheideelement angeordnet sein, das in der Abscheidekammer positioniert ist. Die Gefahr, dass Flüssigkeit in das Saugaggregat eingesaugt wird, kann dadurch gering gehalten werden.Conveniently, a suction pipe is arranged at the turbine inlet, which dips into the separation chamber. In the flow direction of the liquid-air mixture flowing into the separation chamber, the free end of the suction pipe can be arranged at a distance from a separation element which is in the Separation chamber is positioned. The risk of liquid being sucked into the suction unit can thus be kept low.

Das mindestens eine Abscheideelement kann beispielsweise in Form einer Prallwand ausgebildet sein. Vorzugsweise ist die Prallwand in Richtung auf den Saugeinlass der Abscheidekammer konvex gekrümmt.The at least one separation element can be designed, for example, in the form of a baffle wall. The baffle wall is preferably curved convexly in the direction of the suction inlet of the separation chamber.

Bevorzugt ist die mindestens eine Prallwand einstückig mit einem Gehäuse der Abscheideeinheit verbunden. So kann beispielsweise vorgesehen sein, dass das Gehäuse der Abscheideeinheit und die mindestens eine Prallwand gemeinsam ein einteiliges Kunststoffformteil ausbilden.The at least one baffle wall is preferably connected in one piece to a housing of the separation unit. For example, it can be provided that the housing of the separation unit and the at least one baffle wall together form a one-piece plastic molded part.

Die Saugdüse, das Saugaggregat und der Schmutzflüssigkeitstank sind günstigerweise mit der Abscheideeinheit lösbar verbindbar. Insbesondere kann vorgesehen sein, dass die Saugdüse, das Saugaggregat und/oder der Schmutzflüssigkeitstank mit der Abscheideeinheit lösbar verrastbar sind. Dies gibt dem Benutzer die Möglichkeit, das Hartflächenabsauggerät zur Reinigung auf einfache Weise zu demontieren.The suction nozzle, the suction unit and the dirty liquid tank are advantageously releasably connectable to the separation unit. In particular, it can be provided that the suction nozzle, the suction unit and / or the dirty liquid tank can be releasably latched to the separation unit. This allows the user to easily dismantle the hard surface suction device for cleaning.

Bei einer vorteilhaften Weiterbildung der Erfindung weisen die Abscheideeinheit und das Saugaggregat ein gemeinsames Gehäuse auf, an dem der Schmutzflüssigkeitstank und/oder der Handgriff lösbar gehalten sind. Bei einer derartigen Ausgestaltung der Erfindung bilden die Abscheideeinheit und das Saugaggregat eine gemeinsame Baueinheit aus, an der der Schmutzflüssigkeitstank und/oder der Handgriff lösbar gehalten sind. Ergänzend kann vorgesehen sein, dass auch die Saugdüse an dem gemeinsamen Gehäuse von Abscheideeinheit und Saugaggregat lösbar gehalten ist.In an advantageous development of the invention, the separation unit and the suction unit have a common housing on which the dirty liquid tank and / or the handle are detachably held. In such an embodiment of the invention, the separation unit and the suction unit form a common structural unit on which the dirty liquid tank and / or the handle are detachably held. In addition, it can be provided that the suction nozzle is also detachably held on the common housing of the separation unit and suction unit.

Es kann auch vorgesehen sein, dass der Handgriff mit der Abscheideeinheit und/oder mit dem Saugaggregat lösbar verbindbar ist. Bei einer derartigen Ausgestaltung ist es von Vorteil, wenn auch die Abscheideeinheit und das Saugaggregat voneinander getrennt werden können.It can also be provided that the handle can be detachably connected to the separation unit and / or to the suction unit. In such a configuration, it is advantageous if the separation unit and the suction unit can also be separated from one another.

Günstig ist es, wenn das Saugaggregat zusammen mit mindestens einem Teil des Handgriffs eine mit der Abscheideeinheit lösbar verbindbare Baueinheit ausbildet. Eine derartige Ausgestaltung ist insbesondere dann von Vorteil, wenn der mit dem Saugaggregat eine gemeinsame Baueinheit ausbildende Teil des Handgriffs eine wiederaufladbare Batterie und/oder einen Schalter zum Ein- und Ausschalten des Hartflächenabsauggerätes umfasst, denn durch die Ausgestaltung in Form einer gemeinsamen Baueinheit kann eine lösbare elektrische Verbindung zwischen dem die wiederaufladbare Batterie und/oder den elektrischen Schalter aufnehmenden Teil des Handgriffs und dem Saugaggregat entfallen.It is advantageous if the suction unit, together with at least part of the handle, forms a structural unit that can be detachably connected to the separation unit. Such a design is particularly advantageous if the part of the handle that forms a common structural unit with the suction unit comprises a rechargeable battery and / or a switch for switching the hard surface suction device on and off, because the design in the form of a common structural unit means that a removable electrical connection between the part of the handle receiving the rechargeable battery and / or the electrical switch and the suction unit is not required.

Wie bereits erwähnt, wird vom Saugaggregat eine Saugströmung erzeugt, unter deren Wirkung ein Flüssigkeits-Luftgemisch in die Abscheidekammer eingesaugt werden kann. Vom Flüssigkeits-Luftgemisch abgeschiedene Flüssigkeit kann von der Abscheidekammer über den Flüssigkeitsauslass zum Schmutzflüssigkeitstank gelangen und die Luft kann über den Luftauslass in das Saugaggregat einströmen und von diesem in Form von Abluft von außen abgegeben werden. Hierbei ist es von Vorteil, wenn zumindest ein Teil der vom Saugaggregat abgegebenen Abluft durch den Handgriff hindurchführbar ist. Dies ermöglicht es beispielsweise, eine im Handgriff positionierte wiederaufladbare Batterie durch die Abluft des Saugaggregates zu kühlen.As already mentioned, a suction flow is generated by the suction unit, under the effect of which a liquid-air mixture can be sucked into the separation chamber. Liquid separated from the liquid-air mixture can get from the separation chamber via the liquid outlet to the dirty liquid tank and the air can flow into the suction unit via the air outlet and be discharged from the outside in the form of exhaust air. It is advantageous here if at least part of the exhaust air emitted by the suction unit can be passed through the handle. This makes it possible, for example, to cool a rechargeable battery positioned in the handle using the exhaust air from the suction unit.

Günstigerweise umfasst der Handgriff auf seiner der Absaugeinrichtung abgewandten Seite mindestens eine Öffnung zum Ausgeben von Abluft. Die Bedienungsperson kann den Handgriff umgreifen. Die Abluft wird durch den Handgriff hindurchgeführt und auf der der Absaugeinrichtung abgewandten Seite nach außen abgegeben. Eine Beeinträchtigung der Bedienungsperson durch die Abluft kann dadurch verhindert werden.The handle advantageously comprises at least one opening for discharging exhaust air on its side facing away from the suction device. The operator can grip the handle. The exhaust air is passed through the handle and released to the outside on the side facing away from the suction device. This prevents the operator from being impaired by the exhaust air.

Bei einer vorteilhaften Ausführungsform der Erfindung bildet die Abscheideeinheit in Kombination mit dem Handgriff eine Ausnehmung aus, in die das Saugaggregat einsetzbar ist. Bei einer derartigen Ausgestaltung kann das Saugaggregat einerseits an der Abscheideeinheit und andererseits am Handgriff festgelegt werden, beispielsweise mit Hilfe einer lösbaren Rastverbindung.In an advantageous embodiment of the invention, the separation unit, in combination with the handle, forms a recess into which the suction unit can be inserted. In such a configuration, the suction unit be fixed on the one hand to the separation unit and on the other hand to the handle, for example with the aid of a releasable locking connection.

Nimmt der Handgriff mindestens eine wiederaufladbare Batterie auf, so ist es von Vorteil, wenn im Bereich zwischen dem Handgriff und dem Saugaggregat lösbare elektrische Verbindungselemente angeordnet sind, über die die mindestens eine wiederaufladbare Batterie mit einem Elektromotor und/oder mit einer Steuereinrichtung des Elektromotors elektrisch verbindbar ist.If the handle takes at least one rechargeable battery, it is advantageous if releasable electrical connecting elements are arranged in the area between the handle and the suction unit, via which the at least one rechargeable battery can be electrically connected to an electric motor and / or to a control device of the electric motor is.

Eine besonders einfache Montage des Hartflächenabsauggerätes wird bei einer Weiterbildung der Erfindung dadurch erzielt, dass das Saugaggregat einseitig an der Abscheideeinheit gehalten ist.A particularly simple assembly of the hard surface suction device is achieved in a further development of the invention in that the suction unit is held on one side of the separation unit.

Die Abscheideeinheit und der Handgriff können als einteiliges Kunststoffformteil ausgebildet sein, an dem das Saugaggregat lösbar gehalten ist.The separation unit and the handle can be designed as a one-piece molded plastic part on which the suction unit is detachably held.

Das Saugaggregat 218 umfasst eine Saugturbine 244 sowie einen Elektromotor 246, der die Saugturbine 244 um eine Turbinenachse 248 in Drehung versetzt. Zur Steuerung des Elektromotors 246 weist das Saugaggregat 218 eine Steuereinrichtung 250 auf.A separation element in the form of a baffle wall 236, which is spherically curved, is arranged in the separation chamber 232 at a distance from the suction channel 224. On the side of the baffle wall 36 facing away from the suction nozzle 14, a pipe section 238 is arranged, which extends through an air outlet 240 of the separation chamber 32 and is fixed to a turbine inlet 242 of the suction unit 218.

Zusätzlich zum Saugeinlass 234 und zum Luftauslass 240 umfasst die Abscheidekammer 232 einen Flüssigkeitsauslass 252, der von einem Auslasstrichter 254 gebildet wird. Die Abscheidekammer 232 ist von einem Abscheidegehäuse 256 umgeben mit einer Stirnwand 258, die den Saugeinlass 234 aufweist, einer Rückwand 260, die den Luftauslass 240 aufweist, und mit einer Ringwand 270, über die die Rückwand 260 mit der Stirnwand 258 verbunden ist.In addition to the suction inlet 234 and the air outlet 240, the separation chamber 232 comprises a liquid outlet 252, which is formed by an outlet funnel 254.

For this purpose, the handle 222 forms a sleeve 261 which is connected in one piece to the rear wall 260 and to the annular wall 270 of the separator housing 256. The sleeve 261 defines a longitudinal axis 265 of the handle 222, which in the FIG Figure 1 illustrated upright position of the hard surface suction device 200 is aligned essentially vertically.

Das Saugaggregat 218 ist einseitig an der Rückwand 260 des Abscheidegehäuses 256 lösbar gehalten. Hierzu können beispielsweise Rastelemente zum Einsatz kommen, die dem Fachmann an sich bekannt und daher in Figur 1 zur Erzielung einer besseren Übersicht nicht dargestellt sind.The suction unit 218 is detachably held on one side on the rear wall 260 of the separator housing 256. For this purpose, latching elements, for example are used which are known per se to the person skilled in the art and are therefore in Figure 1 are not shown to achieve a better overview.

Beim Hartflächenabsauggerät 200 ist in dessen Saugaggregat 218 eine wiederaufladbare Batterie 267 integriert, die über elektrische Verbindungsleitungen mit der Steuereinrichtung 250 verbunden ist. Über eine Steuerleitung steht die Steuereinrichtung 250 mit einem Schalter 269 in elektrischer Verbindung, der an einer Unterseite 271 des Saugaggregates 218 in einer Vertiefung 273 angeordnet ist. Über eine an der Rückseite 275 des Saugaggregates 218 angeordnete Anschlussbuchse 277 kann die wiederaufladbare Batterie 267 mit einem externen Ladegerät verbunden werden.In the hard surface suction device 200, a rechargeable battery 267 is integrated in its suction unit 218 and is connected to the control device 250 via electrical connecting lines. The control device 250 is electrically connected via a control line to a switch 269, which is arranged in a recess 273 on an underside 271 of the suction unit 218. The rechargeable battery 267 can be connected to an external charger via a connection socket 277 arranged on the rear side 275 of the suction unit 218.

Die den Handgriff 222 ausbildende Hülse 261 ist an ihrem der Abscheideeinheit 216 abgewandten Ende offen ausgebildet. Die Hülse 261 nimmt einen ersten Tankbereich 279 des Schmutzflüssigkeitstanks 222 auf, an den sich außerhalb der Hülse 261 ein zweiter Tankbereich 281 mit deutlich vergrößertem Durchmesser anschließt. Mit seiner Unterseite bildet der Schmutzflüssigkeitstank 220 eine Stellfläche 283, mit der das Hartflächenabsauggerät 200 auf einem Untergrund abgestellt werden kann.The sleeve 261 forming the handle 222 is designed to be open at its end facing away from the separation unit 216. The sleeve 261 accommodates a first tank area 279 of the dirty liquid tank 222, which is adjoined outside the sleeve 261 by a second tank area 281 with a significantly larger diameter. With its underside, the dirty liquid tank 220 forms a floor space 283 with which the hard surface suction device 200 can be placed on a surface.

Der Schmutzflüssigkeitstank 220 des Hartflächenabsauggerätes 200 nimmt eine Befüllungseinrichtung 284 auf mit einem Einfüllkanal 286 und einem Belüftungskanal 288. Flüssigkeit, die in der Abscheidekammer 232 abgeschieden wird, kann über den Auslasstrichter 254 und den Einfüllkanal 286 in den Schmutzflüssigkeitstank 220 gelangen. Aus dem Schmutzflüssigkeitstank 220 kann über den Belüftungskanal 288 Luft in die Abscheidekammer 232 einströmen.The dirty liquid tank 220 of the hard surface suction device 200 accommodates a filling device 284 with a filling channel 286 and a ventilation channel 288. Liquid that is separated in the separation chamber 232 can enter the dirty liquid tank 220 via the outlet funnel 254 and the filling channel 286. Air can flow into the separation chamber 232 from the dirty liquid tank 220 via the ventilation duct 288.

Der Schmutzflüssigkeitstank 220 kann ebenso wie die Saugdüse 214 und das Saugaggregat 218 vom Abscheidegehäuse 256 getrennt werden, so dass der Schmutzflüssigkeitstank 220, die Saugdüse 214 und auch die Abscheidekammer 232 von einer Bedienungsperson bei Bedarf gereinigt werden können. Mittels der Saugturbine 244 kann eine Saugströmung erzeugt werden, so dass ein Flüssigkeits-Luftgemisch über die Saugdüse 214 in die Abscheidekammer 232 eingesaugt werden kann. Die eingesaugte Luft kann vom Saugaggregat über Luftauslassöffnungen 290 der Hülse 261 zugeführt werden. Der erste Tankbereich 279 des Schmutzflüssigkeitstanks 220 und die Hülse 261 definieren zwischen sich einen Luftauslasskanal 292, der sich entlang des ersten Tankbereichs 279 bis zum freien Ende der Hülse 261 erstreckt, so dass die Abluft des Saugaggregates im Bereich zwischen der Hülse 261 und dem aus der Hülse 261 herausragenden zweiten Tankbereich 281 nach außen abgegeben werden kann.The dirty liquid tank 220, like the suction nozzle 214 and the suction unit 218, can be separated from the separator housing 256 so that the dirty liquid tank 220, the suction nozzle 214 and also the separating chamber 232 can be cleaned by an operator if necessary. A suction flow can be generated by means of the suction turbine 244, so that a liquid-air mixture can be sucked into the separation chamber 232 via the suction nozzle 214. The sucked in air can be fed from the suction unit via air outlet openings 290 to the sleeve 261. The first tank area 279 of the dirty liquid tank 220 and the sleeve 261 define an air outlet channel 292 between them, which extends along the first tank area 279 to the free end of the sleeve 261, so that the exhaust air of the suction unit in the area between the sleeve 261 and the from the Sleeve 261 protruding second tank area 281 can be released to the outside.

Eine Bedienungsperson kann das Hartflächenabsauggerät 200 am hülsenförmigen Handgriff 222 unterhalb der Abscheideeinheit 216 umgreifen, wobei das Saugaggregat 218 mit seiner Unterseite 271 im Bereich zwischen Zeigefinger und Daumen auf dem Handrücken der Bedienungsperson aufliegt. Auftretende Kippmomente beim Führen des Hartflächenabsauggerätes 200 entlang einer Hartfläche können dadurch gering gehalten werden. Dies erleichtert die Handhabung des Hartflächenabsauggerätes 200.An operator can grip the hard surface suction device 200 on the sleeve-shaped handle 222 below the separation unit 216, the suction unit 218 resting with its underside 271 in the area between the index finger and thumb on the back of the operator's hand. Tilting moments that occur when guiding the hard surface suction device 200 along a hard surface can thereby be kept low. This facilitates the handling of the hard surface suction device 200.
