Abstract

1. Swimming-pool cleaner for filtering the swimming-pool water and for cleaning the swimming-pool bottom with an electric-motor-driven pump which draws in swimming-pool water through a suction device (15), leads said water through a filter (10) and then pumps it back again into the swimming-pool whereby the suction device, the filter, the motor (1, 2) and the pump are combined to form a unit whose displacement is so great that in normal operation the cleaner, when immersed in the swimming-pool water, projects out of the water only with a part of the suction device so that floating dirt particles are drawn in, wherein the motor (1, 2) is in the form of an induction motor with two-phase low-voltage winding (31, 34) having two coil sets whereby the first winding (31) is supplied with low voltage by a first transformer (30) and the second winding (34) is supplied by a second transformer (32) which in turn is supplied from the mains through the intermediary of a capacitor (33).

Description

Die Erfindung betrifft ein Gerät zum Filtern des Schwimmbadwassers und zum Reinigen des Bodens des Schwimmbades.The invention relates to a device for filtering the swimming pool water and for cleaning the bottom of the swimming pool.

Zur Beseitigung von Feststoff-Verschmutzungen im Schwimmbadwasser wird der Schwimmbadinhalt durch Filter geleitet. Da die Filteraufstellung vom Schwimmbadniveau unabhängig sein soll, ergeben sich vielfältige Schwierigkeiten. Befindet sich das Filter oberhalb des Wasserniveaus, so muss das Filtergefäss vakuumdicht sein und die Umwälzpumpe Selbstsaugereigenschaften haben. Befindet sich das Filter unterhalb des Schwimmbadniveaus, so lässt sich das Filter nicht zum Zwecke des Reinigens öffnen, bevor die Verbindungsleitungen zum Schwimmbad abgesperrt werden. Schliesslich erfordern die Filter im Ansaugbereich Skimmer-Geräte, durch die der Wasserstrom von der Oberfläche abgesaugt wird, wodurch auch schwimmende Schmutzteile in den Filterkreislauf gezogen werden. Diese Skimmer erfordern mechanische Einrichtungen zur Anpassung des Einlaufniveaus an das jeweilige Schwimmbadniveau. Da diese Filtergeräte nicht in der Lage sind, die Schwim bad böden sauberzuhalten, sind in der Regel mit dem Ansaugbereich des Schwimmbadfilters Reinigungsschläuche verbunden, an die Saugbürsten angeschlossen werden können, die von Hand über den Beckenboden geführt werden müssen. Der gesamte mechanische Aufwand von Schwimmbadfiltern ist so gross, dass beispielsweise bei Plastikschwimmbädern die Kosten für die Filteranlage und die Bodenreinigungseinrichtung häufig höher liegen als die für die Schwimmbecken selbst.The pool contents are passed through filters to remove solid contamination in the swimming pool water. Since the filter installation should be independent of the swimming pool level, there are various difficulties. If the filter is above the water level, the filter vessel must be vacuum-tight and the circulation pump must have self-suction properties. If the filter is below the swimming pool level, the filter cannot be opened for cleaning before the connecting lines to the swimming pool are shut off. Finally, the filters in the suction area require skimmer devices, through which the water flow is sucked off the surface, which means that even floating dirt particles are drawn into the filter circuit. These skimmers require mechanical devices to adapt the inlet level to the respective swimming pool level. Since these filter devices are not able to keep the swimming pool floor clean, cleaning hoses are usually connected to the suction area of the swimming pool filter, to which suction brushes can be connected, which have to be moved over the pool floor by hand. The total mechanical complexity of swimming pool filters is so great that, for example in plastic swimming pools, the costs for the filter system and the floor cleaning device are often higher than those for the swimming pools themselves.

Ein weiterer Nachteil aller Filtereinrichtungen besteht darin, dass die Reinigungsgeräte über Schläuche mit dem Becken verbunden werden. Es hat sich gezeigt, dass die Reibungswiderstände der Schläuche und Armaturen wesentlich grösser sind als der Filterdurchlasswiderstand. Dementsprechend werden unverhältnismässig grosse Antriebsleig:ungen erforderlich, was zu hohem Energieverbrauch führt, insbesondere wenn das Filter ganzjährig betrieben wird. Es sind auch schwimmende Filtergeräte bekannt geworden, bei denen die Pumpe im Schwimmbad angeordnet ist, die das Wasser unmittelbar ansaugt und das gefilterte Wasser durch Schlauchleitungen über die Fläche des Beckenbodens verteilt austreten lässt. Bei diesen Geräten kann jedoch kein Oberflächenwasser in das Filter eintreten. Die Einbeziehung des Oberflächenwassers in den Filterkreislauf ist deshalb nicht gelöst. Ausserdem lässt sich mit diesen Geräten der Schwimmbadboden nicht reinigen, sieht man von der aufwirbelnden Wirkung der aus den am Boden liegenden Schläuchen austretenden Wasserstrahlen ab, mit denen loser Staub, nicht jedoch Veralgung beseitigt werden kann.Another disadvantage of all filter devices is that the cleaning devices are connected to the basin via hoses. It has been shown that the frictional resistance of the hoses and fittings is significantly greater than the filter passage resistance. Accordingly, disproportionately large drives are required, which leads to high energy consumption, especially if the filter is operated all year round. Floating filter devices have also become known, in which the pump is arranged in the swimming pool, which draws in the water directly and lets the filtered water escape through hose lines over the surface of the pool floor. With these devices, however, no surface water can enter the filter. The inclusion of surface water in the filter circuit is therefore not resolved. In addition, the pool floor cannot be cleaned with these devices, apart from the swirling effect of the water jets emerging from the hoses lying on the floor, with which loose dust, but not algae, can be removed.

Die Erfindung beseitigt all diese Nachteile. Gemäss der Erfindung besteht das Filtergerät aus einer Pumpe, die keine selbstsaugenden Eigenschaften zu besitzen braucht, aus einer Filtereinheit und einer Ansaugeinrichtung, die Oberflächenwasser absaugt. Die erfindungsgemässen Filtergeräte werden vorzugsweise röhrenförmig aufgebaut, so dass sie auch als Sauggerät zur Absaugung des Beckenbodens eingesetzt werden können.The invention overcomes all of these disadvantages. According to the invention, the filter device consists of a pump that does not need to have self-priming properties, a filter unit and a suction device that sucks off surface water. The filter devices according to the invention are preferably constructed in tubular form, so that they can also be used as suction devices for suctioning off the pelvic floor.

Um den Motor herum ist das Filterelement angeordnet. Oberhalb des Filters ist ein Verdrängerkörper vorgesehen, der das Motorgewicht kompensiert, so dass das ganze Gerät schwimmt, wobei die Ansaugvorrichtung in der Wasseroberfläche liegt. Am Fuss kann eine Austrittsdüse angeordnet sein, die einen Strahl zur Aufwirbelung von beweglichen Schmutzteilchen am Beckenboden erzeugt.The filter element is arranged around the motor. A displacer is provided above the filter, which compensates for the motor weight so that the entire device floats, the suction device being in the water surface. An outlet nozzle can be arranged at the foot, which generates a jet for whirling up movable dirt particles on the pool floor.

Das so aufgebaute Gerät eignet sich auch als von Hand geführte Saugbürste zur Reinigung des Schwimmbadbodens. Durch teilweises Befüllen eines verschliessbaren Raumes mit Wasser lässt sich die Eintauchtiefe des Eintrittsbereichs relativ zur Wasseroberfläche so einstellen, dass nur eine dünne Schicht von Oberflächenwasser in das Filter eingesaugt wird. Das Gerät wird bevorzugt unter Zwischenschaltung eines ausserhalb des Schwimmbades angeordneten Schutzspannungstransformators an das Netz angeschlossen. Als Pumpe sieht die Erfindung bevorzugt eine Anordnung vor, bei der der Motor über eine magnetische Übertragungsvorrichtung durch eine hermetisch dichtende Wandung hindurch das Pumpenschaufelrad antreibt. Hierdurch ist sichergestellt, dass trotz betriebsmässig sich ändernder Wasserdrücke, die auf das Motorgehäuse wirken, kein Wasser in das Innere des Motors eindringen kann, wie dies beim Einsatz von Wellendichtungen grundsätzlich möglich ist.The device constructed in this way is also suitable as a hand-operated suction brush for cleaning the pool floor. By partially filling a closable space with water, the immersion depth of the entry area relative to the water surface can be adjusted so that only a thin layer of surface water is sucked into the filter. The device is preferably connected to the network with the interposition of a protective voltage transformer arranged outside the swimming pool. As a pump, the invention preferably provides an arrangement in which the motor drives the pump impeller via a magnetic transmission device through a hermetically sealing wall. This ensures that, despite operationally changing water pressures that act on the motor housing, no water can penetrate into the interior of the motor, as is fundamentally possible when using shaft seals.

Die Erfindung soll anhand von Figuren beschrieben werden.

  • Figur 1 zeigt das erfindungsgemässe Gerät als schwimmendes Filtergerät.
  • Figur 2 zeigt das gleiche Gerät als Bodenabsauggerät.
  • Figur 3 zeigt den mechanischen Aufbau des Gerätes und des Motors.
The invention will be described with reference to figures.
  • Figure 1 shows the device according to the invention as a floating filter device.
  • Figure 2 shows the same device as a floor suction device.
  • Figure 3 shows the mechanical structure of the device and the motor.

Figur 1 zeigt einen Querschnitt durch das erfindungsgemässe Gerät. Im unteren Teil des Gerätes befindet sich der Motor. Stator 1 und Rotor 2 sind in einem hermetisch abgedichteten Gehäuse 3 ängeordnet, welches vom Pumpenraum durch eine sphärische Trennwand 4 getrennt ist. Ein konkaver umlaufender Magnet 5 bewirkt die Mitnahme und Stabilisierung des konvexen umlaufenden Magneten 6, der mit dem Schaufelrad 7 eine Einheit bildet. Die Wasseransaugung erfolgt durch den Ansaugstutzen 8. Das austretende Wasser tritt in den Pumpenraum 9 ein und durchströmt dann den aus gefaltetem Filterpapier gebildeten Hohlzylinder 10 und sammelt sich im Ringbereich 11, um durch die Düsen 12 auszutreten. Dem Ansaugbereich 8 ist der Grobfilter 13 vorgeschaltet, so dass sich Blätter und andere Grobschmutzteile im Raum 14 sammeln. Der Schwimmkörper 15 weist Durchbrüche 16 auf, durch die das Oberflächenwasser in den Raum 14 eintritt. Durch Öffnungen 17 lässt sich Wasser in den Hohlraum 18 einführen. Hierdurch ist eine einmalige Justierung der Eintauchtiefe möglich. Durch das Rohr 19 gelangt durch die Öffnungen 16 eintretende Luft in den Ansaugbereich des Schaufelrades 7 und wird in den Raum 9 gefördert. Alsdann durchdringt die Luft das Filter 10 und tritt durch die Öffnungen 20 wieder aus. Durch ein Belüftungsventil 21 kann die Luft in einstellbarer Rate angesaugt werden, was zur erwünschten Sauerstoffanreicherung des Schwimmbadwassers führt. Die Mutter 22 hält den Schwimmkörper 15 auf dem Gewindebolzen 23. Durch Lösen dieser Schraube wird der Schwimmkörper 15 vom Zylindergehäuse 24 getrennt. Das Grobfilter 13 ist nunmehr zugänglich. Nach Abnehmen des kegeligen Gehäuses 26 kann der Filterzylinder 10 ausgetauscht werden. Unterhalb des Motors ist eine Leuchte 25 angeordnet, die zur abendlichen Ausleuchtung des Schwimmbades dient.Figure 1 shows a cross section through the inventive device. The motor is located in the lower part of the device. Stator 1 and rotor 2 are arranged in a hermetically sealed housing 3, which is separated from the pump chamber by a spherical partition 4. A concave rotating magnet 5 causes entrainment and stabilization of the convex rotating magnet 6, which forms a unit with the paddle wheel 7. The water is sucked in through the suction port 8. The escaping water enters the pump chamber 9 and through then flows the hollow cylinder 10 formed from folded filter paper and collects in the ring region 11 to emerge through the nozzles 12. The coarse filter 13 is connected upstream of the suction area 8, so that leaves and other coarse dirt particles collect in the space 14. The floating body 15 has openings 16 through which the surface water enters the space 14. Water can be introduced into the cavity 18 through openings 17. This makes it possible to adjust the immersion depth once. Air entering through the openings 19 enters the suction area of the impeller 7 through the openings 16 and is conveyed into the space 9. The air then passes through the filter 10 and exits through the openings 20. The air can be sucked in at an adjustable rate through a ventilation valve 21, which leads to the desired oxygenation of the swimming pool water. The nut 22 holds the floating body 15 on the threaded bolt 23. By loosening this screw, the floating body 15 is separated from the cylinder housing 24. The coarse filter 13 is now accessible. After removing the conical housing 26, the filter cylinder 10 can be replaced. A lamp 25 is arranged below the motor and is used for the evening illumination of the swimming pool.

Es hat sich als vorteilhaft erwiesen, Halogenlampen, die eine thermisch extrem hoch belastete Oberfläche aufweisen, einzusetzen. Da diesen Lampen grosse Lufträume zugeordnet sein müssen, würden sie zu einem unerwünschten Auftrieb führen. Die Erfindung sieht für diese Lampen und Unterwasserlampen im allgemeinen die Füllung des Lampeninneren mit einer thermostabilen Flüssigkeit, z.B. Silikonöl, vor. Durch diese Massnahme kann der Lampeninnenraum auf wenige Kubikzentimeter reduziert werden.It has proven to be advantageous to use halogen lamps which have a thermally extremely highly stressed surface. Since large air spaces must be assigned to these lamps, they would lead to an undesirable buoyancy. The invention generally provides for these lamps and underwater lamps to fill the inside of the lamp with a thermostable liquid, e.g. Silicone oil, before. This measure allows the lamp interior to be reduced to a few cubic centimeters.

Figur 2 zeigt das gleiche Gerät in umgekehrter Stellung, wobei ein Bürstenring 27, der über einen Stiel 28 am Boden geführt werden kann, mittels Spannring 29 mit dem Ansaugkörper 15 des Gerätes leicht lösbar verbunden ist. Zur Verminderung des Auftriebs können die Verdrängerräume 18 (Fig.1) geflutet werden.Figure 2 shows the same device in the reverse position, with a brush ring 27, which is guided by a handle 28 on the floor can be easily detachably connected to the suction body 15 of the device by means of a clamping ring 29. To reduce the buoyancy, the displacement spaces 18 (FIG. 1) can be flooded.

Figur 3 zeigt das Schaltbild des Netzanschlussgerätes und der Beleuchtung. Ein erster Trafo 30 versorgt die Hauptwicklung 31 des Motors mit Niederspannung, ein zweiter Trafo 32, der über den Kondensator 33 gespeist wird, liefert phasenverschobene Niederspannung für die Hilfsphasenwicklung 34 des Motors. Durch die Umschaltung des Schalters 35 können die Leuchten 36 und 37 mit den Transformatoren verbunden werden. Der Motor ist dann abgeschaltet.Figure 3 shows the circuit diagram of the power supply unit and the lighting. A first transformer 30 supplies the main winding 31 of the motor with low voltage, a second transformer 32, which is fed via the capacitor 33, supplies phase-shifted low voltage for the auxiliary phase winding 34 of the motor. By switching the switch 35, the lights 36 and 37 can be connected to the transformers. The engine is then switched off.
