Skimmer für ein SchwimmbeckenSkimmer for a swimming pool
Die Erfindung betrifft einen Skimmer (Oberflachenabsauger) , über den das in einem Schwimmbecken ablaufende oder abgesaugte Wasser abgeführt wird, wobei in einem Gehäuse ein Schwimmwehr über ein Scharnier schwenkbar angelenkt ist.The invention relates to a skimmer (surface suction), via which the water running off or drawn off in a swimming pool is discharged, a swimming weir being pivotally articulated via a hinge in a housing.
Skimmer haben die Aufgabe, verschmutztes, oberflächennahes Wasser einem Filter zuzuführen. Zu den Verschmutzungen können auch Feststoffpartikel, wie Laub, Staub oder ähnliche aufschwimmende Teile gehören. Das über das Skimmerwehr in das Skimmergehäuse eintretende Wasser wird zu diesem Zweck über einen Abfluß, in dem ggf. ein Haar- und Faserfangkorb angeordnet ist, einem Filter zur Wasserreinigung zugeführt. Hierbei werden häufig Pumpen als Absaugeinrichtungen verwendet. Etwaige im Schwimmbecken vorgesehene Überläufe sowie Bodenabläufe bzw. deren Anschlüsse sind zumeist über eine gemeinsame Leitung verbunden, so dass die gesamte Schwimmbeckensteuerung zur Absaugung der Wasseroberfläche bzw. des Boden über einen Flüssigkeitsstromregler gesteuert werden kann, so dass nur eine zum Flüssigkeitsfilter führende Leitung erforderlich ist.Skimmers have the task of feeding contaminated, near-surface water to a filter. Soiling can also include solid particles such as leaves, dust or similar floating parts. For this purpose, the water entering the skimmer housing via the skimmer weir is fed to a filter for water purification via a drain, in which a hair and fiber collecting basket may be arranged. Here pumps are often used as suction devices. Any overflows provided in the swimming pool and floor drains or their connections are usually connected via a common line, so that the entire pool control for suctioning the water surface or the floor can be controlled via a liquid flow controller, so that only one line leading to the liquid filter is required.

Ein einbetonierter oder aufgesetzter Skimmer wird von der Beckeninnenwandseite her ggf. durch eine rahmenförmige Blende abgeschlossen, um Plattierungsränder abzudecken. Nach dem Stand der Technik bekannte Schwimmbecken bestehen aus Stahl, Aluminium oder einem Kunststoff, insbesondere Polyester.Skimmers are built into the niches provided in the swimming pool wall at about the level of the water surface, or are placed on the pool edge in the case of retrofitting in concrete swimming pools or when replacing a non-identical skimmer. A concrete or attached skimmer is closed off from the inside of the pool by a frame-shaped cover, if necessary, to cover the edges of the plating. To Swimming pools known in the prior art consist of steel, aluminum or a plastic, in particular polyester.
Die bisher bekannten Schwimmwehre haben eine obere gerade Kante, so dass das ablaufende bzw. abgepumpte Wasser stets mit der gleichen Geschwindigkeit über diese Kante geführt wird. Das Schwimmwehr ist über ein Scharnier (Drehgelenk) zu befestigt, dass in Richtung des Wasserablaufes ablaufendes bzw. abgepumptes Wasser das Schwimmwehr aus der Vertikalen in eine geneigte Stellung kippt. Bei abgeschalteter Pumpe bzw. fehlendem Wasserdruck von der Schwimmbeckenseite auf das Schwimmwehr schwenkt dieses in eine mehr oder weniger vertikale Stellung zurück. Der hierzu notwendige Auftrieb bei der Pendelbewegung des Schwimmwehres kann beispielsweise durch Anbringen eines geschlossenporigen Schaumstoffes gewährleistet werden. Nachteilige ist bei den nach dem Stand der Technik verwendeten Scharnieren, dass diese nicht wartungsfrei sind, so dass bei ungünstigen Toleranzen der Lagerstellen bzw. durch Verunreinigungen durch Kalk oder Schmutz die Drehbewegung bis zum Verklemmen gehemmt werden kann und eine einwandfreie Funktion nicht mehr gewährleistet ist. Insbesondere dann, wenn das Schwimmwehr in einer Schräglage klemmend verharrt, besteht bei abgeschalteter Pumpe die Gefahr, dass bereits jenseits des Schwimmwehrs, z.B. im Fangkorb liegende Störstoffe (Blätter etc.) wieder aufgewirbelt werden und ins Schwimmbecken zurückgelangen.The previously known swimming weirs have an upper straight edge, so that the drained or pumped water is always guided over this edge at the same speed. The swimming weir is attached via a hinge (swivel joint) so that water running or pumped out in the direction of the water drain tilts the swimming weir from the vertical into an inclined position. When the pump is switched off or there is no water pressure from the swimming pool side onto the swimming weir, it swings back into a more or less vertical position. The necessary buoyancy during the pendulum movement of the swimming weir can be ensured, for example, by attaching a closed-cell foam. A disadvantage of the hinges used according to the prior art is that they are not maintenance-free, so that in the event of unfavorable tolerances of the bearing points or due to contamination by lime or dirt, the rotary movement can be inhibited until jamming and perfect functioning can no longer be guaranteed. In particular, if the lifeguard remains jammed in an inclined position, there is a risk with the pump switched off that already beyond the lifeguard, e.g. interfering substances (leaves etc.) in the collecting basket are whirled up again and returned to the swimming pool.
Es ist Aufgabe der vorliegenden Erfindung, einen Skimmer zu schaffen, dessen Schwimmwehr die vorgenannten Nachteile vermeidet . Diese Aufgabe wird durch einen Skimmer nach Anspruch 1 gelöst. Erfindungsgemäß ist das Scharnier zur Befestigung des Schwimmwehres als wiederholt lösbares Rastscharnier ausgebildet, wobei bei sperrendem Eingriff des Rastscharniers das Schwimmwehr in vertikaler Stellung gehalten wird. Vorzugsweise wird als Rastscharnier ein Filmscharnier verwendet.It is an object of the present invention to provide a skimmer, the swimming weir of which avoids the aforementioned disadvantages. This object is achieved by a skimmer according to claim 1. According to the invention, the hinge for fastening the swimming weir is designed as a repeatedly releasable locking hinge, the swimming weir being held in a vertical position when the locking hinge is locked. A film hinge is preferably used as the locking hinge.
Nach einer weiteren Ausgestaltung der Erfindung ist das Rastscharnier mit einer Saugeinrichtung (Pumpe) derart verbunden, dass beim Abschalten der Pumpe die Rastverbindung in sperrenden Eingriff geführt wird und beim Einschalten der Pumpe wieder gelöst wird. Durch diese Maßnahme wird wirksam verhindert, dass das Schwimmwehr bei Nichtabsaugung in vertikaler Stellung verbleibt. Neben dem Vorteil, dass im Bereich des Skimmers noch auf der Schwimmbeckenwasseroberfläche noch vorhandene Schmutzpartikel bei abgeschalteter Pumpe aus dem Skimmer nicht zurückgelangen können, hat diese Ausgestaltung den weiteren Vorteil, dass die Anbringung eines Filmscharniers kostengünstiger zu fertigen ist, da dieses Scharnier dann als fester Bestandteil des vorzugsweise aus Kunststoff gefertigten Schwimmwehres ist.According to a further embodiment of the invention, the locking hinge is connected to a suction device (pump) such that when the pump is switched off, the locking connection is guided into locking engagement and is released again when the pump is switched on. This measure effectively prevents the swimming weir from remaining in a vertical position when not suctioned. In addition to the advantage that dirt particles still present on the surface of the swimming pool in the area of the skimmer cannot return from the skimmer when the pump is switched off, this configuration has the further advantage that the attachment of a film hinge is less expensive to manufacture, since this hinge is then an integral part the preferably made of plastic swimming weir.
Nach einer weiteren Ausgestaltung der Erfindung weist die obere Kante des Schwimmwehres mindestens eine Einbuchtung auf, die vorzugsweise als einzige Einbuchtung vorgesehen ist, die im wesentlichen mittig angeordnet ist.According to a further embodiment of the invention, the upper edge of the swimming weir has at least one indentation which is preferably provided as the only indentation which is arranged essentially in the center.
Überraschenderweise hat sich herausgestellt, dass eine solche Einbuchtung eine (zusätzliche) Strömung unterhalb der unmittelbaren Wasseroberfläche erzeugt, durch die ein Synergieeffekt auf die an der Wasseroberfläche herrschende Strömung ausgeübt wird. Ein Skimmer hat, bezogen auf die zu reinigende Wasseroberfläche eines Schwimmbeckens einen verhältnismäßig kleinen Einlaß. Wird Wasser von der Oberfläche über den Skimmer mittels einer Pumpe abgesaugt, neigt sich das Schwimmwehr aus der Vertikalen in eine Schrägstellung, so dass die gesamte Schwimmwehroberkante unterhalb der Wasseroberfläche liegt. Durch die Einbuchtung wird die Sogwirkung und damit die Strömungsgeschwindigkeit des ablaufenden Wassers deutlich erhöht, so dass die im Einzugsbereich der Skimmeröffnung befindlichen Schmutzpartikel, die sich auf der Wasseroberfläche des Schwimmbeckens befinden, wirkungsvoll abgesaugt werden. Verunreinigungen, wie Blätter, Insekten, Staub etc., können somit in kürzester Zeit in den Skimmer-Auffangkorb geführt werden. Nach dem Abschalten der Pumpe, mittels der das abgesaugte Wasser zu einem Filter geführt wird, schwenkt das Schwimmwehr wieder in die im wesentlichen vertikale Lage zurück, so dass die komplette obere Kante einschließlich Einbuchtung oberhalb des Wasserspiegels steht. Hiermit wird verhindert, dass der Schmutz aus dem Auffangkorb wieder zurück in das Schwimmbecken gelangen kann.Surprisingly, it has been found that such an indentation generates an (additional) flow below the immediate water surface, through which a synergy effect is exerted on the current prevailing on the water surface. A skimmer has, based on the one to be cleaned Water surface of a swimming pool has a relatively small inlet. If water is drawn off from the surface via the skimmer by means of a pump, the swimming weir tilts vertically into an inclined position so that the entire upper edge of the swimming weir lies below the water surface. The indentation significantly increases the suction effect and thus the flow velocity of the water running off, so that the dirt particles located in the catchment area of the skimmer opening, which are located on the water surface of the swimming pool, are effectively extracted. Contaminants such as leaves, insects, dust etc. can thus be put into the skimmer collection basket in the shortest possible time. After the pump, by means of which the extracted water is led to a filter, is switched off, the swimming weir swings back into the essentially vertical position, so that the entire upper edge, including the indentation, is above the water level. This prevents the dirt from the collecting basket from getting back into the swimming pool.
Nach einer weiteren Ausgestaltung der Erfindung ist die vorgesehene Einbuchtung konkav und/oder mit einem konstanten Radius ausgebildet, womit sich weitgehend unerwünschte Turbulenzen an der Schwimmwehrkante vermeiden lassen. Die Einbuchtung erstreckt sich vorzugsweise über etwa 35 bis 45 %, insbesondere 40 %, der Gesamtbreite des Schwimmwehrs. Die Höhe der Einbuchtung, gemessen an deren tiefstem Punkt, beträgt 20 bis 30 mm.According to a further embodiment of the invention, the indentation provided is concave and / or has a constant radius, with which largely undesirable turbulence at the edge of the swimming weir can be avoided. The indentation preferably extends over approximately 35 to 45%, in particular 40%, of the overall width of the swimming weir. The height of the indentation, measured at its lowest point, is 20 to 30 mm.

Der in Fig. 1 bis 3 dargestellte Skimmer besteht aus einem Gehäuse 10, mit einem Skimmerhals 11 und einem schwenkbar angeordneten Skimmerwehr 12 sowie einem vor einem Wasserauslaß 27 eingehängten Haar- oder Faserfangkorb 13. Der Skimmerhals 11 ragt über die Schwimmbeckeninnenwandfläche 14 hinaus und weist einen Absatz 15 mit Bohrungen 16 auf, in denen Metallhülsen 17 mit einem Innengewinde eingelassen sind, die zur Befestigung von Schrauben 18 dienen. Zur Schwimmbeckeninnenseite hin wird der Skimmerhals 11 rundum durch einen gleichzeitig als Blende dienenden Flansch 19 abgedeckt, die selbst Bohrungen 20 aufweist, durch welche die Schrauben 18 hindurchgesteckt werden können. Entsprechend kongruent liegende Bohrungen sind in der Schwimmbeckenwand 21 vorgesehen, die aus Stahl, Aluminium, Polyester oder auch aus Holz mit einer Innenauskleidung bestehen kann. Für die radiale Abdichtung sorgen zwei Dichtungen 22, 23, welche zwischen dem Flansch 19 und der Schwimmbeckenwand 21 einerseits und zwischen der Schwimmbeckenwand 21 und dem Absatz 15 des Skimmer- halses 11 angeordnet sind. Durch die in den Zeichnungen dargestellte Konstruktion wird deutlich, dass das entlang der Skim- merhalsmantelinnenfläche 24 einströmende Wasser keine Dichtung und Ausschnitte passieren kann, die allmählich verrotten bzw. defektanfällig wären. Das in das Skimmergehäuse über das Schwimmwehr 12 einfließende Wasser gelangt über den Ausflußtrichter 25 und über den Haar- oder Faserfangkorb 13 zu dem Abfluß 27. Die mittlere Öffnung des Flansches 19 ist so groß ausgebildet, dass das vorderseitige schmalere Skimmerhals- teil 26 in der dargestellten Weise eingreifen kann. Hierdurch ist es möglich, den Flansch 19 mittels der Schrauben 18 mit dem entsprechenden Druck an die Dichtung 22 anzupressen bzw. einen entsprechenden Druck auch über die Schraubbefestigung auf die Dichtung 23 auszuüben.The skimmer shown in Fig. 1 to 3 consists of a housing 10, with a skimmer neck 11 and a pivotably arranged skimmer weir 12 and a hair or fiber basket 13 suspended in front of a water outlet 27. The skimmer neck 11 projects beyond the inner wall surface 14 of the pool and has one Paragraph 15 with holes 16, in which metal sleeves 17 are embedded with an internal thread, which are used to fasten screws 18. Towards the inside of the swimming pool, the skimmer neck 11 is covered all around by a flange 19 which also serves as an aperture and which itself has bores 20 through which the screws 18 can be inserted. Correspondingly congruent holes are provided in the swimming pool wall 21, which can consist of steel, aluminum, polyester or even wood with an inner lining. The radial seal is provided by two seals 22, 23, which are arranged between the flange 19 and the swimming pool wall 21 on the one hand and between the swimming pool wall 21 and the shoulder 15 of the skimmer neck 11. The construction shown in the drawings makes it clear that the water flowing in along the inner surface of the skimmer neck shell 24 cannot pass through a seal and cutouts which would gradually rot or be susceptible to defects. That in the skimmer housing over that Water entering the weir 12 passes through the outflow funnel 25 and the hair or fiber basket 13 to the drain 27. The central opening of the flange 19 is so large that the narrow skimmer neck part 26 on the front can engage in the manner shown. This makes it possible to press the flange 19 onto the seal 22 with the appropriate pressure by means of the screws 18 or to exert a corresponding pressure on the seal 23 via the screw fastening.
Erfindungsgemäß ist das Scharnier, mit dem das Schwimmwehr an dem Skimmergehäuse befestigt ist, als lösbares Rastscharnier 30 ausgebildet, wobei bei sperrendem Eingriff des Rast- scharnieres das Schwimmwehr 12 in vertikaler Stellung gehalten wird. Insbesondere ist das Rastscharnier als Filmscharnier 30 ausgebildet und derart mit einer Pumpe verbunden, dass beim Abschalten dieser Pumpe das Schwimmwehr aufgrund des Auftriebst in die senkrechte Stellung schwenkt und das Filmscharnier 30 sperrend einrastet. Wird die Pumpe wieder eingeschaltet, wird elektromechanisch die Rastverbindung dearretiert und damit das Schwimmwehr wieder freigegeben.According to the invention, the hinge with which the swimming weir is fastened to the skimmer housing is designed as a releasable locking hinge 30, the swimming weir 12 being held in a vertical position when the locking hinge interlocks. In particular, the locking hinge is designed as a film hinge 30 and is connected to a pump in such a way that when this pump is switched off, the lifeguard pivots into the vertical position due to the buoyancy and the film hinge 30 snaps into place in a locking manner. If the pump is switched on again, the snap-in connection is unlocked electromechanically and the lifeguard is released again.
Das Schwimmwehr 12 besitzt darüber hinaus eine obere Kante, die eine Einbuchtung 29 aufweist, die im wesentlichen mittig angeordnet ist. Die Einbuchtung 29 ist konkav und mit konstantem Radius ausgebildet und besitzt im vorliegenden Fall eine Breite von ca. 40 % der gesamten Breite des Schwimmwehres 12 sowie eine Höhe von etwa 25 mm. Das Schwimmwehr 12 besteht aus einem aufschwimmbaren Körper mit geschlossenen Hohlräumen, die vorzugsweise im Bereich der oberen Kante 28 bzw. im oberen Bereich der Seitenkanten liegen. Alternativ hierzu kann der erwünschte Auftrieb auch durch Anbringung eines geschlossenpo- rigen Schaumstoffes realisiert werden. Durch die Wellenbewegung, Wind oder das Abpumpen des Wassers, wird eine unruhige Wasseroberfläche erzeugt, wobei das Schwimmwehr die in Fig. 1 und 2 dargestellte Stellung einnimmt, in der ein Teil des Wassers über die geradlinigen seitlichen Kantenbereiche des Schwimmwehres 12 abfließt. Durch die Einbuchtung 29 ist ein erweiterter Ablaufbereich geschaffen, der in diesem Bereich die Wasserströmung in den Skimmer verstärkt. Schaltet man die Pumpe ab bzw. fehlt es an einer Druck- bzw. Sogwirkung, so richtet sich das Schwimmwehr 12 auftriebsbedingt in eine Vertikalstellung auf, in der es über das Filmscharnier 30 einrastet. Diese Rastverbindung besteht so lange bis die Pumpe wieder eingeschaltet wird. The swimming weir 12 also has an upper edge which has an indentation 29 which is arranged essentially in the center. The indentation 29 is concave and has a constant radius and in the present case has a width of approximately 40% of the entire width of the swimming weir 12 and a height of approximately 25 mm. The swimming weir 12 consists of a floatable body with closed cavities, which are preferably in the area of the upper edge 28 or in the upper area of the side edges. Alternatively, the desired buoyancy can also be achieved by attaching a closed foam can be realized. Due to the wave movement, wind or the pumping out of the water, a restless surface of the water is generated, with the swimming weir assuming the position shown in FIGS. 1 and 2, in which part of the water flows off over the straight lateral edge areas of the swimming weir 12. The indentation 29 creates an extended drainage area which increases the water flow into the skimmer in this area. If the pump is switched off or there is no pressure or suction effect, the swimming weir 12 is raised due to the buoyancy to a vertical position in which it engages via the film hinge 30. This latching connection continues until the pump is switched on again.
