Description

Die Erfindung bezieht sich auf ein Reinigungsgerät, insbesondere für die Reinigung von Schwimmbecken, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cleaning device, in particular for the cleaning of swimming pools, according to the preamble of patent claim 1.

Schwimmbad-Reinigungsroboter werden im professionellen Bereich eingesetzt, insbesondere in olympischen Schwimmbecken oder grossen Hotelpoolanlagen. Die bisherigen Roboter können selbständig vom Beckenrand aus ins Wasser fahren, sich selber absenken, das elektrische Kabel hinter sich her ziehen und über unterschiedliche Navigationssysteme, je nach Ausstattung, den ganzen Schwimmbeckenboden systematisch abfahren und zuletzt wieder an den Ort zurückkehren und auftauchen, wo der Roboter die Arbeit begonnen hat. Die Bedienungsperson muss dann nur noch mit ein paar Handgriffen die Filter reinigen. Der Roboter ist mit Bürsten sowie mit groben und feinen Filtern ausgestattet. Bei der Reinigung wird lediglich der Schmutz, welcher sich am Boden des Schwimmbeckens angesammelt hat, losgelöst und mittels einer elektrischen Umwälzpumpe in den Filtern aufgefangen.Pool cleaning robots are used in the professional field, especially in Olympic swimming pools or large hotel pool facilities. The previous robots can drive independently from the edge of the pool into the water, lower themselves, pull the electrical cable behind him and systematically shut down the entire pool floor using different navigation systems, depending on the equipment, and finally return to the place and emerge, where the robot the work has started. The operator then only has to clean the filters in a few simple steps. The robot is equipped with brushes as well as coarse and fine filters. When cleaning only the dirt that has accumulated at the bottom of the pool, detached and collected by means of an electric circulation pump in the filters.

Professionelle Schwimmbäder sind typischerweise mit externen, sehr leistungsfähigen Umwälzpumpen ausgestattet, um das Wasser chemisch aufzubereiten und zu filtern. Oft sind auch UV-Behandlungen des aufzubereitenden Wassers vorgesehen. Das Wasser ist somit meist optisch sauber und die chemischen Zusätze verhindern die Algenbildung.Professional swimming pools are typically equipped with external, high-performance circulating pumps to chemically treat and filter the water. Often, UV treatments of the water to be treated are provided. The water is therefore usually optically clean and the chemical additives prevent the formation of algae.

Freibäder sind meistens im Winter geschlossen, aber aus baustatischen Gründen bleibt das Wasser bei der Überwinterung im Becken, so dass dann sehr viel Schmutz anfällt und sich unterschiedliche Algen bilden. Manche Algen können nur schlecht an den Wänden anhaften, die eine glatte Oberfläche aufweisen. Vielfach sind die Wände mit Folien beschichtet, welche mit chemischen Substanzen behandelt sind, um den Algenwuchs zu verhindern. Bei Platten können sich die Algen allerdings vor allem an den Fugen einnisten. Manche Algen, insbesondere Schwarzalgen, haften fast unlösbar speziell am Boden.Outdoor pools are mostly closed in winter, but for structural reasons, the water remains in the hibernation in the pool, so that then accumulates much dirt and form different algae. Some algae can only badly adhere to the walls, which have a smooth surface. In many cases, the walls are coated with films which are treated with chemical substances in order to prevent algae growth. In the case of slabs, however, the algae are able to nest on the joints, above all. Some algae, especially black algae, adhere almost indissolubly, especially on the ground.

Der Einsatz von den üblichen Unterwasserrobotern genügt aber bei weitem nicht, um die vollständige Reinigung bei der Wiederinbetriebnahme eines solchen Schwimmbeckens zu bewirken. Vor Inbetriebnahme wird deshalb das Schwimmbadwasser vollständig abgelassen oder ausgepumpt und gleich mehrere Arbeiter müssen in mühsamster Hand- und Fussarbeit das Schwimmbad reinigen. Dabei kommen typischerweise Chemikalien und unterschiedlich harte Bürsten zum Einsatz. Es müssen ferner spezielle Schuhe getragen werden, um genügend Bodenhaftung zu erzeugen. Auch werden Bürsten an den Schuhen befestigt, um mit dem Körpergewicht einen erhöhten Druck auf die Bürste zu erreichen. Dies ist jedes Jahr ein teures und aufwendiges Unterfangen. Alternativ können Hochdruckreiniger eingesetzt werden, um insbesondere den Algenbefall und Biofilm zu beseitigen.However, the use of the usual underwater robots is far from sufficient to effect complete cleaning when recommending such a swimming pool. Before startup, therefore, the swimming pool water is completely drained or pumped out and several workers have to clean the swimming pool in the most laborious manual and footwork. Typically, chemicals and brushes of different hardness are used. Special shoes must also be worn to provide sufficient traction. Also brushes are attached to the shoes to achieve an increased pressure on the brush with the body weight. This is an expensive and expensive undertaking every year. Alternatively, high-pressure cleaners can be used, in particular to eliminate algae infestation and biofilm.

In letzter Zeit werden vermehrt sogenannte Naturbäder bzw. Freibäder mit biologischer Wasseraufbereitung gebaut, bei welchen das Wasser auch umgewälzt, aber über eine natürliche Wasseraufbereitung gereinigt wird. So wird das Wasser beispielsweise durch einen natürlichen Teich oder Weiherboden gefiltert, der auch Pflanzen enthält. Das Ziel dieser Naturbäder bzw. Freibäder mit biologischer Wasseraufbereitung ist, mit möglichst wenig Frischwasser und ohne chemische Zusätze auszukommen. Die Wände und Böden dieser Naturbäder bzw. Freibäder mit biologischer Wasseraufbereitung sind in der Regel mit natürlichen Steinen gebaut, die üblicherweise eine rauhere Oberfläche aufweisen als bei herkömmlichen Schwimmbadbecken. Die Reinigung von solchen Naturbädern bzw. Freibädern mit biologischer Wasseraufbereitung lässt sich wegen des stärkeren Algenbefalls durch die herkömmlichen Schwimmbadreinigungsroboter kaum bewerkstelligen.Recently, more and more so-called natural pools and outdoor pools are built with biological water treatment, in which the water is also circulated, but purified by a natural water treatment. For example, the water is filtered through a natural pond or pond, which also contains plants. The aim of these natural baths or outdoor pools with biological water treatment is to get along with as little fresh water and without chemical additives. The walls and floors of these natural baths or outdoor pools with biological water treatment are usually built with natural stones, which usually have a rougher surface than in conventional Swimming pool. The cleaning of such natural baths or outdoor pools with biological water treatment can hardly accomplish because of the stronger algae infestation by the conventional pool cleaning robot.

Um solche Naturbäder bzw. Freibäder mit biologischer Wasseraufbereitung zu reinigen, werden deshalb rollende Bürsten eingesetzt, welche längere Borsten haben und mit abrasivem Material überzogen sind. Die Bürsten müssen dann regelmässig ausgetauscht werden, was erhöhte Kosten mit sich führt, und die Reinigungsleistung ist trotzdem unbefriedigend. Deshalb wird eine andere Lösung gewählt, indem zusätzliches Personal vom Beckenrand aus mit Handbürsten oder mit Hochdruckreinigern die Naturbäder bzw. Freibäder mit biologischer Wasseraufbereitung reinigt.To clean such natural baths or outdoor pools with biological water treatment, rolling brushes are therefore used, which have longer bristles and are coated with abrasive material. The brushes must then be replaced regularly, which entails increased costs, and the cleaning performance is still unsatisfactory. Therefore, another solution is chosen by additional staff cleans the poolside with hand brushes or high-pressure cleaners or natural baths or pools with biological water treatment.

In EP-A-1 551 571 ist eine Reinigungsvorrichtung mit Hochdruckreinigungsstrahlen beschrieben, welche mittels gekröpften Rohren in einem flachen Winkel von etwa 5° bis 10° auf die Oberfläche des zu reinigenden Schwimmbeckens gerichtet sind. Die Reinigung mit den Hochdruckstrahlen findet somit in einem relativ schmalen Streifen statt, so dass der Reinigungsroboter mindestens die dreifache Wegstrecke zurücklegen muss als üblich, um den gesamten Boden des Schwimmbeckens abzudecken. Ferner ist eine Reinigung mit den Hochdruckstrahlen an den Randbereichen des Schwimmbeckens nicht möglich. Weitere bekannte Reinigungsgeräte werden in EP 1 997 567 A1 und JP 2001 276754 A beschrieben.In EP-A-1 551 571 is a cleaning device described with high-pressure cleaning jets, which are directed by means of cranked pipes at a shallow angle of about 5 ° to 10 ° on the surface of the swimming pool to be cleaned. The cleaning with the high-pressure jets thus takes place in a relatively narrow strip, so that the cleaning robot must travel at least three times the distance than usual to cover the entire bottom of the pool. Furthermore, cleaning with the high-pressure jets at the edge areas of the swimming pool is not possible. Other well-known cleaning devices are in EP 1 997 567 A1 and JP 2001 276754 A described.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, die genannten Nachteile zu vermeiden, und ein Schwimmbad-Reinigungsgerät anzugeben, das eine effiziente und kostengünstigere Reinigung von professionellen Schwimmbädern und auch von Naturbädern bzw. Freibädern mit biologischer Wasseraufbereitung und auch von Zierbecken ermöglicht.The present invention is based on the object to avoid the disadvantages mentioned, and to provide a swimming pool cleaning device that allows efficient and cost-effective cleaning of professional swimming pools and natural pools or outdoor pools with biological water treatment and also ornamental pool.

Diese Aufgabe wird gelöst durch ein Schwimmbad-Reinigungsgerät mit den Merkmalen des Patentanspruchs 1.This object is achieved by a swimming pool cleaning device having the features of patent claim 1.

Das erfindungsgemässe Reinigungsgerät hat den grossen Vorteil, dass nunmehr mit bedeutend weniger Aufwand und wesentlich schneller ein Schwimmbeckenboden gereinigt werden kann, wobei stark anhaftender Schmutz gelöst und entfernt werden soll.The inventive cleaning device has the great advantage that now with significantly less effort and much faster a pool floor can be cleaned, with strongly adhering dirt to be removed and removed.

In den Figuren sind jeweils für dieselben Elemente dieselben Bezugszeichen verwendet, wenn nichts anderes erwähnt ist.In the figures, the same reference numerals are used for the same elements, unless otherwise stated.

Figur 1 zeigt ein Reinigungsgerät 1 für die Reinigung von Schwimmbecken in perspektivischer Darstellung und von unten gesehen, welches seitlich zwei Raupen 2 und 3 mit einer Innenverzahnung aufweist, die jeweils zwischen zwei von einem (nicht ersichtlichen) Elektromotor angetriebenen Zahnrädern 4 und 5 eingespannt sind. Vorne und hinten sind Bürstenrollen 6 und 7 vorgesehen, welche ebenfalls über einen Zahnriemen 8 (siehe Figur 2) von den Zahnrädern 4 und 5 angetrieben werden. Zwischen den vorderen Zahnrädern 4 ist eine vordere Achse 10 und zwischen den hinteren Zahnrädern 5 ist eine hintere Achse 11 angeordnet. Ferner ist ein (nicht ersichtliches) Gehäuse mit einer Gehäusebasis 13 vorgesehen, welche hinten zwei nebeneinander angeordnete, trapezförmige Ansaugöffnungen 14 und 15 und vorne zwei kreisringförmige, nebeneinander angeordnete Ausschnitte 16 und 17 aufweist, welche durch eine mittige Kreisplatte 18 und mit der Gehäusebasis 13 verbundenen Stege 19 gebildet sind. FIG. 1 shows a cleaning device 1 for the cleaning of swimming pools in a perspective view and seen from below, which laterally has two beads 2 and 3 with an internal toothing, which are each clamped between two of a (not shown) electric motor driven gears 4 and 5. Front and rear brush rollers 6 and 7 are provided, which also has a toothed belt 8 (see FIG. 2 ) are driven by the gears 4 and 5. Between the front gears 4, a front axle 10 and between the rear gears 5, a rear axle 11 is arranged. Further, a (not apparent) housing is provided with a housing base 13, which rear two adjacent trapezoidal suction 14 and 15 and front two annular, juxtaposed cutouts 16 and 17 which through a central circular plate 18 and connected to the housing base 13 Webs 19 are formed.

Wie aus Figur 2 ersichtlich, ist oberhalb der Ansaugöffnung 14 eine Absaugpumpe 20 und oberhalb der Ansaugöffnung 15 eine Absaugpumpe 21 vorgesehen. Ferner ist rein schematisch ein Filtergehäuse 22 für die (nicht-dargestellten) Reinigungsfilter vorgesehen.How out FIG. 2 can be seen, above the suction port 14, a suction pump 20 and above the suction port 15, a suction pump 21 is provided. Furthermore, a filter housing 22 for the (not shown) cleaning filter is provided purely schematically.

In den Figuren 3 und 4 sind nun auf der Unterseite des Reinigungsgerätes 1 knapp oberhalb der Gehäusebasis 13 zwei Rotoren 25 mit einem Rotorarm 26 drehbar an einer Druckwasserleitung befestigt, dessen Enden mit je einer Düse 27 versehen sind. Die Austrittsöffnungen der Düsen 27 sind in einem Winkel von 10° bis 25° zur Senkrechten zur Gehäusebasis 13 ausgerichtet, so dass der austretende Hochdruck-Wasserstrahl in einem Winkel von 10° bis 25° auf die zu reinigende Fläche auftritt. Damit wird der Rotor 25 automatisch vom Hochdruck-Wasserstrahl in Rotation versetzt. Je nach Druck des Wasserstrahls und Durchmesser der Austrittöffnung der Düsen 27 wird eine schnellere oder weniger schnellere Rotation erreicht. Eine Rotationsgeschwindigkeit von 100 bis 600 Umdrehungen in der Minute hat sich für die Reinigung der von Schwarzalgen befallenen Bodenfläche als äusserst wirksam erwiesen. Der Abstand der Düsen 27 zum Boden beträgt in etwa 3 bis 4 cm. Die Rotation der Rotoren 25 kann zusätzlich durch den Antrieb der Zahnrädern 4 und 5 oder durch einen separaten Motor erfolgen. Die Kreis- oder Abdeckplatte 18 verhindert, dass der Rotor 25 nicht durch gröberen Schmutz wie kleine Äste in der Drehbewegung behindert werden kann.In the FIGS. 3 and 4 are now on the underside of the cleaning device 1 just above the housing base 13, two rotors 25 rotatably mounted with a rotor arm 26 to a pressurized water line, the ends are each provided with a nozzle 27. The outlet openings of the nozzles 27 are aligned at an angle of 10 ° to 25 ° to the perpendicular to the housing base 13, so that the exiting high-pressure water jet occurs at an angle of 10 ° to 25 ° on the surface to be cleaned. Thus, the rotor 25 is automatically rotated by the high-pressure water jet in rotation. Depending on the pressure of the water jet and the diameter of the outlet opening of the nozzles 27, a faster or less rapid rotation is achieved. A rotational speed of 100 to 600 revolutions per minute has proven to be extremely effective in cleaning the soil affected by black algae. The distance of the nozzle 27 to the ground is approximately 3 to 4 cm. The rotation of the rotors 25 may additionally by the drive of the gears 4 and 5 or by a separate motor. The circular or cover plate 18 prevents the rotor 25 can not be hindered by coarser dirt such as small branches in the rotational movement.

Die (nicht dargestellte) Hochdruckwasserpumpe für den Hochdruck-Wasserstrahl wird ausserhalb des Schwimmbeckens aufgestellt und über einen armierten Schlauch zur Druckwasserleitung des Reinigungsgeräts 1 geführt. Dieser Schlauch kann mit dem Gerätestromversorgungskabel für die Absaugpumpen 20 und 21, für den elektrischen Antriebsmotor und für die elektrische Steuerung verbunden sein. Zusätzlich kann dieses mit dem Schlauch verbundene Kabel mit Auftriebskörper oder Schwimmer versehen sein, so dass der Schlauch auf dem Wasser schwimmt und so bei der Hin- und Herbewegung über den Schwimmbadboden das Reinigungsgerät 1 nicht behindert.The (not shown) high-pressure water pump for the high-pressure water jet is placed outside the pool and passed over a reinforced hose to the pressurized water line of the cleaning device 1. This hose can be connected to the device power supply cable for the suction pumps 20 and 21, for the electric drive motor and for the electrical control. In addition, this cable connected to the hose may be provided with buoyancy or float, so that the hose floats on the water and so does not hinder the cleaning device 1 when reciprocating over the pool floor.

Das Wasser, welches der Hochdruckwasserpumpe zugeführt wird, kann direkt aus dem Schwimmbecken entnommen werden. Die Hochdruckwasserpumpe erzeugt einen Wasserdruck von 100 bis 300 bar. Die normale Reinigungspumpenleistung des Reinigungsgeräts 1 beträgt etwa 5 bis 15 Liter pro Sekunde und durch das Ansaugen dieser Wassermenge durch die grossen Ansaugöffnungen 14 und 15 saugt das Reinigungsgerät 1 sich gleichsam am Beckenboden an. Diese Saugwirkung bewirkt auch, das Reinigungsgerät 1 trotz des Hochdruck-Wasserstrahls auf dem Boden zu halten, weil der Saugdruck bedeutend grösser ist als die entgegengesetzte Kraft, welche durch den aus den Düsenaustritte ausströmenden Wasserstrahl erfolgt. Mit dem rotierenden Wasserstrahl wird der am Schwimmbecken anhaftende Schmutz gelöst und über die Ansaugöffnungen 14 und 15 von den Pumpen 20 und 21 abgesaugt.The water supplied to the high-pressure water pump can be taken directly from the swimming pool. The high-pressure water pump generates a water pressure of 100 to 300 bar. The normal cleaning pump power of the cleaning device 1 is about 5 to 15 liters per second and by sucking this amount of water through the large intake ports 14 and 15 sucks the cleaning device 1, as it were at the bottom of the pool. This suction also causes the cleaning device 1 to keep on the ground despite the high-pressure water jet, because the suction pressure is significantly greater than the opposite force, which is effected by the water jet flowing out of the nozzle exits. With the rotating jet of water adhering to the pool dirt is released and sucked through the suction ports 14 and 15 of the pumps 20 and 21.

Das Reinigungsgerät 1 kann auch ohne Bürstenrollen ausgebildet, einfach mit Laufrädern oder Laufrollen bestückt sein, um als Anhänger an einem bestehenden Reinigungsroboter angehängt zu werden. Dies erlaubt eine einfache und kostengünstige Nachrüstung von bestehenden Reinigungssystemen.The cleaning device 1 can also be designed without brush rollers, simply be equipped with wheels or rollers to be attached as a trailer to an existing cleaning robot. This allows a simple and cost-effective retrofitting of existing cleaning systems.
