Description

Die Erfindung betrifft ein selbstfahrendes Reinigungsgerät, insbesondere für Schwimmbecken, mit einem Grundgehäuse, in welchem ein Antrieb für das Reinigungsgerät integriert und zumindest eine Reinigungsbürste sowie ein Ansaugkanal vorgesehen ist, über den zu reinigende Flüssigkeit mittels einer Pumpe in einen Filterraum förderbar ist.The invention relates to a self-propelled cleaning device, in particular for swimming pools, with a basic housing in which a drive for the cleaning device is integrated and at least one cleaning brush and an intake duct is provided, via which liquid to be cleaned can be conveyed into a filter space by means of a pump.

Zur Reinigung von Wasserbecken, insbesondere Schwimmbecken, ist es bekannt, Reinigungsgeräte einzusetzen, mit denen die Reinigung des Beckenbodens und ggfs. der Beckenwände durchgeführt werden kann, wobei die Gerätebedienung ausserhalb des Wasserbeckens erfolgt. Beispielsweise zeigt die EP-A 0 099 489 ein derartiges Reinigungsgerät, in welchem beidseits eines Grundgehäuses rotierende Reinigungsbürsten vorgesehen sind, wobei die zu reinigende Flüssigkeit angesaugt und in einen Filter transportiert wird, der dem Grundgehäuse aufsitzt.For the cleaning of water pools, in particular swimming pools, it is known to use cleaning devices with which the cleaning of the pool floor and possibly the pool walls can be carried out, the device being operated outside the pool. For example, EP-A 0 099 489 shows a cleaning device of this type, in which rotating cleaning brushes are provided on both sides of a basic housing, the liquid to be cleaned being sucked in and transported into a filter which is seated on the basic housing.

Über entsprechende Fühler wird bei einem Anstossen an eine Beckenwand der Antrieb umgeschaltet und ggfs. die Fahrtrichtung des Reinigungsgerätes geändert.The drive is switched over and the driving direction of the cleaning device changed, if necessary, by means of appropriate sensors.

Dieses Reinigungsgerät arbeitet vorzüglich, besitzt jedoch infolge seines hohen Filteraufbaus einen grossen Strömungswiderstand.This cleaning device works excellently, but has a large flow resistance due to its high filter structure.

Aufgabe der vorliegenden Erfindung ist es, ein Reinigungsgerät der oben genannten Art zu entwickeln, welches kompakt und strömungstechnisch verbessert gebaut ist und bei welchem eine verbesserte Ansaugung und Filterung der zu reinigenden Flüssigkeit gewährleistet wird.The object of the present invention is to develop a cleaning device of the type mentioned above, which is of compact construction and improved in terms of flow technology and in which an improved suction and filtering of the liquid to be cleaned is ensured.

Zur Lösung dieser Aufgabe führt, dass sich der Filterraum über fast die ganze Oberseite des Grundgehäuses erstreckt und von einem Gehäusedeckel abgedeckt ist.To solve this problem, the filter space extends over almost the entire top of the basic housing and is covered by a housing cover.

Bei diesem Reinigungsgerät entfällt ein hoher Filteraufbau, so dass der Strömungswiderstand vermindert und damit Energie beim Betrieb des Reinigungsgerätes eingespart wird. Ebenfalls ist die ästhetische Formgestaltung verbessert.This cleaning device does not have a high filter structure, so that the flow resistance is reduced and energy is saved when operating the cleaning device. The aesthetic design is also improved.

Der Gehäusedeckel ist über ein Scharnier mit dem Grundgehäuse verbunden. Wird dieser Gehäusedeckel abgehoben, so ist der Filterraum und insbesondere eine in diesem Filterraum liegende Filtermatte frei zugänglich. Diese Filtermatte kann leicht gereinigt oder ausgetauscht werden.The housing cover is connected to the basic housing via a hinge. If this housing cover is lifted off, the filter space and in particular a filter mat located in this filter space is freely accessible. This filter mat can be easily cleaned or replaced.

Bevorzugt liegt die Filtermatte im Filterraum Keilrinnen auf, welche dem Grundgehäuse eingeformt sind. Diese Keilrinnen können quer oder parallel zur Gehäuselängsachse verlaufen und ermöglichen eine grossflächige Dränage des gefilterten Wassers.The filter mat preferably lies in the filter space in wedge channels which are molded into the basic housing. These V-shaped channels can run transversely or parallel to the longitudinal axis of the housing and enable large-scale drainage of the filtered water.

In den Filterraum mündet ein Anschlussstutzen ein, der mit einer Zentralkammer in Verbindung steht. In dieser Zentralkammer ist die Pumpe angeordnet. Bevorzugt handelt es sich bei der Pumpe um eine Wirbelradpumpe, welche kraftschlüssig mit dem Gehäuseantrieb, d.h. mit dem Motor oder einem Getriebeteil, verbunden ist. Die Pumpe muss in beiden Drehrichtungen, d.h. sowohl bei Vor- wie auch Rückwärtsfahrt, fördern können.A connection piece opens into the filter chamber and is connected to a central chamber. The pump is arranged in this central chamber. The pump is preferably a vortex pump, which is non-positively connected to the housing drive, i.e. is connected to the engine or a gear part. The pump must rotate in both directions, i.e. can promote both forwards and backwards.

Von der Zentralkammer führen Kanäle zu entsprechenden Ansaugöffnungen, welche der Reinigungsbürste zugeordnet sind. Bevorzugt verlaufen diese Kanäle in einem Winkel zur Gehäuselängsachse, wodurch eine hohe Querströmung von beiden Seiten zu den Ansaugöffnungen stattfindet.Channels lead from the central chamber to corresponding suction openings which are assigned to the cleaning brush. These channels preferably run at an angle to the longitudinal axis of the housing, as a result of which there is a high cross flow from both sides to the suction openings.

In einer verbesserten Ausführungsform der vorliegenden Erfindung ist die Reinigungsbürste über ein Hebelgelenk mit dem Grundgehäuse verbunden. Dieses Hebelgelenk kann mittig angeordnet und kardanisch ausgebildet sein. Das Hebelgelenk ist ferner so ausgebildet, dass sich die Reinigungsbürste Unebenheiten des Beckenbodens angleichen kann. Hierzu dient auch, dass die Reinigungsbürste bevorzugt aus zwei jeweils seitlich des Hebelgelenks angeordneten Bürstenwalzen besteht, welche getrennt bewegbar sind.In an improved embodiment of the present invention, the cleaning brush is connected to the basic housing via a lever joint. This lever joint can be arranged in the center and be designed as a cardan. The lever joint is also designed so that the cleaning brush can adjust unevenness in the pelvic floor. It is also used for this that the cleaning brush preferably consists of two brush rollers which are each arranged to the side of the lever joint and which can be moved separately.

Hierdurch wird auch kleineren Unebenheiten Rechnung getragen.This also takes smaller unevenness into account.

Die Reinigungsbürste sollte bevorzugt mit dem Antrieb des Reinigungsgerätes selbst, beispielsweise mit entsprechenden angetriebenen Rädern, verbunden sein. Dies kann über Zahnriemen geschehen.The cleaning brush should preferably be connected to the drive of the cleaning device itself, for example to correspondingly driven wheels. This can be done using timing belts.

Vorzugsweise schliesst in Fahrtrichtung nach hinten noch eine zusätzliche Querbürste zusammen mit der Reinigungsbürste einen Ansaugraum ein. Hierdurch wird ebenfalls die entsprechende Ansaugströmung verbessert.Preferably, an additional cross brush together with the cleaning brush encloses a suction space in the direction of travel to the rear. This also improves the corresponding intake flow.

Ein erfindungsgemässes Reinigungsgerät R für Schwimmbecken weist ein Grundgehäuse 1 auf, welches fahrbar ausgestaltet ist. Das Fahren geschieht auf entsprechenden, ggfs. profilierten, beidseits des Grundgehäuses 1 angeordneten Fahrbändern 2, welche endlos ausgestaltet und über zwei beabstandete Räder 3 und 4 oder Umlenkrollen gelegt sind. Zwischen beiden Rädern 3 und 4 ist zum Fahrgrund 5 hin eine Bandführung 6 vorgesehen.A cleaning device R according to the invention for swimming pools has a basic housing 1 which is designed to be mobile. Driving takes place on corresponding, possibly profiled, conveyor belts 2 arranged on both sides of the basic housing 1, which are endless and are placed over two spaced wheels 3 and 4 or deflection rollers. A band guide 6 is provided between the two wheels 3 and 4 towards the driving surface 5.

Andererseits dieser Bandführung 6 drückt eine Spannrolle 7 auf das Fahrband 2. Die beidseitig angeordneten Fahrbänder 2 sind im übrigen bevorzugt raupenförmig ausgebildet.On the other hand, this belt guide 6 presses a tensioning roller 7 onto the conveyor belt 2. The conveyor belts 2 arranged on both sides are preferably caterpillar-shaped.

Im vorliegenden Ausführungsbeispiel soll bevorzugt eine Achse 8 der Hinterräder 3 angetrieben sein. Für diesen Antrieb 9, der in Figur 1 nur schematisch dargestellt ist, ist ein Motor vorgesehen. Der Motor kann über ein Getriebe 10 mit der Achse 8 verbunden sein. Für den Motor ist ferner noch ein Leistungsteil sowie eine Steuerlogik vorgesehen. Ein Schwimmkabel wird über einen nicht näher gezeigten Stecker trennbar mit einem in Figur 3 angedeuteten Anschluss 17 verbunden.In the present exemplary embodiment, an axle 8 of the rear wheels 3 should preferably be driven. A motor is provided for this drive 9, which is only shown schematically in FIG. 1. The motor can be connected to the axis 8 via a gear 10. A power unit and control logic are also provided for the motor. A floating cable is connected to a connector 17 indicated in FIG.

Frontwärtig ist an das Grundgehäuse 1 eine Kontaktleiste 18 angesetzt, welche beispielsweise eine Berührung mit einer Wand des Schwimmbeckens an die Steuerlogik meldet. Ferner befindet sich an der Rückwand 19 des Gehäuses 1 eine Umschaltleiste 20, welche ebenfalls ein Umschalten des Antriebs 9 auf Vorwärts- oder Rückwärtsfahrt bewirken kann. Dies ist aber nur beispielhaft genannt und nicht Gegenstand der vorliegenden Erfindung.At the front, a contact strip 18 is attached to the basic housing 1, which, for example, reports a contact with a wall of the swimming pool to the control logic. Furthermore, there is a switch bar 20 on the rear wall 19 of the housing 1, which can likewise cause the drive 9 to switch to forward or reverse travel. However, this is only mentioned as an example and is not the subject of the present invention.

Ferner befindet sich frontwärtig an dem Grundgehäuse 1 eine Reinigungsbürste 21. Diese Reinigungsbürste 21 ist, wie in Figur 2 gezeigt, durch ein etwa mittig angeordnetes Hebelgelenk 22 mit dem Grundgehäuse 1 verbunden. Dabei handelt es sich um eine kardanische Aufhängung der links und rechts des Hebelgelenks 22 angeordneten Bürstenwalzen 23 und 24, wobei nicht nur eine Vertikalbewegung der Reinigungsbürste 21 in Richtung x, sondern auch ein Pendeln jeder Bürstenwalze 23 bzw. 24 möglich ist, wie dies durch den Doppelpfeil 25 sowie die strichpunktierte Linie 26 angedeutet wird. Durch diese Aufhängung kann die Reinigungsbürste 21 bzw. die Bürstenwalze 23 und 24 sich Unebenheiten des Beckenbodens anpassen.Furthermore, there is a cleaning brush 21 on the front of the basic housing 1. As shown in FIG. 2, this cleaning brush 21 is connected to the basic housing 1 by a lever joint 22 arranged approximately in the center. This is a cardanic suspension of the brush rollers 23 and 24 arranged on the left and right of the lever joint 22, not just one Vertical movement of the cleaning brush 21 in the direction x, but also an oscillation of each brush roller 23 or 24 is possible, as is indicated by the double arrow 25 and the dash-dotted line 26. This suspension allows the cleaning brush 21 or the brush roller 23 and 24 to adapt to unevenness in the pelvic floor.

Jede Bürstenwalze 23 bzw. 24 wird noch von Zahnriemen 27 durchschnitten, welche für ein Rotieren der Reinigungsbürste 21 sorgen. Dabei sind diese Zahnriemen 27 nicht näher gezeigt mit den vorderen Rädern 4 des Antriebs der Fahrbänder 2 verbunden.Each brush roller 23 or 24 is also cut by toothed belts 27, which ensure that the cleaning brush 21 rotates. These toothed belts 27 are not shown in more detail connected to the front wheels 4 of the drive of the conveyor belts 2.

Seitlich ragen von der Reinigungsbürste 21 noch weitere Reinigungsborsten 28 ab.Additional cleaning bristles 28 protrude laterally from the cleaning brush 21.

Hinter der Reinigungsbürste 21 ist im Gehäuse 1 ein Ansaugkanal 29 vorgesehen, dessen erster Teil in den Figuren 4 und 5 näher dargestellt ist.Behind the cleaning brush 21, an intake duct 29 is provided in the housing 1, the first part of which is shown in more detail in FIGS. 4 and 5.

Nahe der Reinigungsbürste 21 mündet der Ansaugkanal 29 über Ansaugöffnungen 31 in einer Bodenplatte 30 des Grundgehäuses 1 aus. Im vorliegenden Ausführungsbeispiel sind zwei solcher Ansaugöffnungen 31 gezeigt. Dies soll nur beispielhaft sein. Von den Ansaugöffnungen 31 führen schräge Kanäle 32 zu einer Zentralkammer 33 (siehe Figur 1). Diese Kanäle 32 verlaufen in einem Winkel zur Längsachse A des Grundgehäuses 1, wodurch die Ansaugströmung wesentlich verbessert ist. Die Ansaugströmung selbst ist durch Pfeile gekennzeichnet.In the vicinity of the cleaning brush 21, the suction channel 29 opens out via suction openings 31 in a base plate 30 of the basic housing 1. In the present exemplary embodiment, two such suction openings 31 are shown. This is only meant to be an example. Inclined channels 32 lead from the suction openings 31 to a central chamber 33 (see FIG. 1). These channels 32 run at an angle to the longitudinal axis A of the basic housing 1, as a result of which the intake flow is substantially improved. The intake flow itself is indicated by arrows.

Von der Zentralkammer 33 führt ein Anschlussstutzen 34 in einen Filterraum 35, der sich beinahe über das gesamte Grundgehäuse erstreckt. Durch die Bezugszahl 35' ist angedeutet, dass sich dieser Filterraum 35 auch frontwärtig fortsetzt und zwar auch beidseitig des Anschlussstutzens 34.A connecting piece 34 leads from the central chamber 33 into a filter space 35 which extends almost over the entire basic housing. The reference number 35 ′ indicates that this filter space 35 also continues from the front and also on both sides of the connecting piece 34.

Im Filterraum 35 liegt dem Grundgehäuse 1 eine Filtermatte 37 auf, wobei sich ein Teil 37' der Filtermatte 37 auch in dem Filterraumteil 35' befindet. Zum Grundgehäuse 1 hin stützt sich die Filtermatte 37 auf Keilrinnen 39 ab, in welchen die gefilterte Flüssigkeit seitlich aus dem Filterraum 35 abgeführt werden kann. Die Keilrinnen 39 können selbstverständlich auch parallel zur Längsachse A verlaufen.A filter mat 37 lies on the base housing 1 in the filter chamber 35, a part 37 'of the filter mat 37 also being located in the filter chamber part 35'. Towards the basic housing 1, the filter mat 37 is supported on wedge channels 39, in which the filtered liquid can be removed laterally from the filter chamber 35. The V-grooves 39 can of course also run parallel to the longitudinal axis A.

Über eine Pumpe, welche vorzugsweise als Wirbelradpumpe 40 ausgebildet und mit dem Antrieb 9 oder einem entsprechenden Getriebeteil des Antriebs 9 gekoppelt ist, wird die zu filternde Flüssigkeit durch die Ansaugöffnungen 31 und die Kanäle 32 in die Zentralkammer 33 angesaugt und in den Filterraum 35 gedrückt. Sofern der Pumpenantrieb, was wünschenswert ist, mit dem Geräteantrieb 9 kraftschlüssig verbunden ist, muss die Pumpe in beiden Drehrichtungen (Vor- bzw. Rückwärtsfahrt) fördern können. Zudem soll sie in der Lage sein, die anfallenden Schmutzstoffe ohne Vorfiltern in den nachgeschalteten Filterraum 35 fördern zu können. Diese Möglichkeit bietet eine Wirbelradpumpe 40 mit konzentrisch angeordnetem Ringgehäuse.The liquid to be filtered is sucked through the suction openings 31 and the channels 32 into the central chamber 33 and pressed into the filter chamber 35 via a pump, which is preferably designed as a vortex wheel pump 40 and is coupled to the drive 9 or a corresponding gear part of the drive 9. If the pump drive, which is desirable, is non-positively connected to the device drive 9, the pump must be able to deliver in both directions of rotation (forwards or backwards). In addition, it should be able to convey the resulting contaminants into the downstream filter space 35 without prefilters. This possibility is provided by a vortex pump 40 with a concentrically arranged ring housing.

Der Filterraum 35 wird im übrigen von einem Gehäusedeckel 41 abgedeckt, wobei dieser Gehäusedeckel 41 über Scharniere 42 mit dem Grundgehäuse 1 verbunden ist. Dadurch, dass der Filterraum 35 in das Reinigungsgerät R selbst integriert ist, können die Aussenabmessungen des Reinigungsgerätes R extrem gering gehalten werden, was vorteilhafte Auswirkungen auf den Strömungswiderstand des Reinigungsgerätes und die ästhetische Formgestaltung hat. Wesentlich ist dabei, dass der verwendete Kunststoff genügende Formfestigkeit besitzt.The filter chamber 35 is otherwise covered by a housing cover 41, this housing cover 41 being connected to the basic housing 1 via hinges 42. Because the filter space 35 is integrated into the cleaning device R itself, the external dimensions of the cleaning device R can be kept extremely small, which has advantageous effects on the flow resistance of the cleaning device and the aesthetic design. It is essential that the plastic used has sufficient dimensional stability.

Die verwendete Filtermatte 37 wird zwischen dem aufklappbaren Gehäusedeckel 41 in einem nicht näher gezeigten Falz eingespannt. Ggfs. kann hierzu noch ein separater aufklappbarer Filterdeckel vorgesehen sein.The filter mat 37 used is clamped between the hinged housing cover 41 in a not shown fold. If necessary. a separate hinged filter cover can be provided for this purpose.

Die Flüssigkeit strömt über den Anschlussstutzen 34 und deren mit der Filtermatte 37 deckungsgleichen Öffnung in den Filterraum 35. Das filtrierte Wasser tritt auf der Unterseite der Filtermatte 37 aus, wobei die Keilrinnen 39 für eine grossflächige Dränage des gefilterten Wassers sorgen. Die Abflussbedingungen sind so definiert, dass über die ganze Filtermatte 37 gleichmässige Abströmverhältnisse eintreten.The liquid flows through the connecting piece 34 and its opening, which is congruent with the filter mat 37, into the filter space 35. The filtered water emerges on the underside of the filter mat 37, the wedge channels 39 ensuring a large-area drainage of the filtered water. The outflow conditions are defined in such a way that uniform outflow conditions occur over the entire filter mat 37.

Die Keilrinnen 39 können auch beispielsweise durch einen entsprechenden Stützkörper, wie ein perforiertes Blech, gebildet sein. Ferner ist als Variante eine Abströmung direkt oder über kalibrierte Bohrungen auf die Geräteunterseite möglich.The wedge channels 39 can also be formed, for example, by a corresponding support body, such as a perforated sheet. Furthermore, an outflow is possible directly or via calibrated holes on the underside of the device.

In Figur 5 sind noch beidseits Gehäuseabdeckungen 58 erkennbar, welche insbesondere den Antrieb 9 bzw. die Fahrbänder 2 schützen. Des weiteren ist in Fahrtrichtung nach den Ansaugöffnungen 31 eine Querbürste 59 vorgesehen, welche zusammen mit der Reinigungsbürste 21 einen Ansaugraum 60 ausbildet. Zusammen mit der geometrischen Ausgestaltung der Kanäle 32 findet in dem Ansaugraum 60 eine hohe Querströmung von beiden Seiten vzu den Ansaugöffnungen 31 statt. Der dadurch erzielte Strömungseffekt saugt die von der Reinigungsbürste 21 gelösten Verunreinigungen wie auch den in Fugen abgesetzten Schlamm und Sand optimal ab.In FIG. 5, housing covers 58 can also be seen on both sides, which in particular protect the drive 9 or the traveling belts 2. Furthermore, a transverse brush 59 is provided in the direction of travel after the suction openings 31, which together with the cleaning brush 21 forms a suction space 60. Together with the geometrical configuration of the channels 32, a high cross-flow from both sides to the suction openings 31 takes place in the suction space 60. The resulting flow effect optimally sucks off the contaminants loosened by the cleaning brush 21 as well as the sludge and sand deposited in joints.
