Description

Die vorliegende Erfindung betrifft eine Teichpumpe mit einem Gehäuse, mit einem Ansauganschluß, dem ein mit Durchgangsschlitzen ausgebildeter Ansaugbereich einer Gehäuseschale zugeordnet ist, mit einem Druckanschluß, der über eine in dem Gehäuse angeordneten Pumpeinrichtung mit dem Ansauganschluß in Fluidkommunikation steht, mit einem Motor zum Antreiben der Pumpeinrichtung und mit einer Steuereinrichtung zum Steuern der Pumpeinrichtung und des Motors.The present invention relates to a pond pump with a housing, with a suction port, which is associated with a through-slots suction portion of a housing shell, with a pressure port which is in fluid communication via a pump disposed in the housing means with the suction port, with a motor for driving the Pumping device and with a control device for controlling the pumping device and the motor.

Solche Teichpumpen sind im Stand der Technik allgemein bekannt wie z.B. aus DE-A-100 43 668 . Sie werden am Boden eines Teiches oder Beckens positioniert. Das Gehäuse der Teichpumpe ist als Grobfilter ausgebildet und weist Schlitze auf, durch die Wasser in das Gehäuse eindringen kann, nicht aber Blätter, kleine Zweige und andere gröbere Teilchen. Das Wasser wird durch eine im Gehäuse angeordnete Pumpenrichtung in einen hinter der Grobfilterschale liegenden Ansauganschluß gesaugt und über einen Druckanschluß in eine Druckleitung gedrückt, die das Wasser an einem freien Ende abgibt. In solchen Teichpumpen wird zur regelmäßigen Reinigung ausschließlich Wasser aus dem Bodenbereich des Teiches oder Beckens angesaugt. Mit einer solchen Pumpe ist es nicht möglich, auch Wasser von der Teichoberfläche anzusaugen, um auch diese zu reinigen.Such pond pumps are well known in the art such as out DE-A-100 43 668 , They are positioned at the bottom of a pond or basin. The housing of the pond pump is designed as a coarse filter and has slots through which water can penetrate into the housing, but not leaves, small branches and other coarse particles. The water is sucked by a pump disposed in the direction of the pump into a behind the coarse filter shell suction port and pressed via a pressure connection in a pressure line, which emits the water at a free end. In such pond pumps for regular cleaning only water from the bottom of the pond or basin is sucked. With such a pump, it is not possible to suck in water from the pond surface to clean these too.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Teichpumpe zu schaffen, mit der Wasser bei gegebenem Ansaugvolumen wahlfrei vom Bodenbereich eines Teiches oder Beckens und/oder von der Wasseroberfläche desselben angesaugt werden kann.The object of the present invention is therefore to provide a pond pump, with the water at a given intake volume can be optionally sucked from the bottom of a pond or pool and / or from the water surface thereof.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Ansauganschluß zusätzlich ein Ansaugstutzen zugeordnet ist, der in Bezug zu dem Ansauganschluß verstellbar angeordnet ist, derart, dass ein Ansaugvolumen des Ansauganschlusses auf den Ansaugstutzen und den Ansaugbereich aufteilbar ist.The object is achieved in that the intake port is additionally associated with an intake manifold, which is arranged adjustable in relation to the intake port, such that a suction volume of the intake port to the intake manifold and the intake is divisible.

Mit der erfindungsgemäßen Teichpumpe kann nunmehr über den Ansaugstutzen eine Ansaugleitung an der Teichpumpe angebracht werden, die im oberen Bereich eines Wasserstandes endet, so dass aus diesem Bereich Wasser angesaugt werden kann, wobei das Ansaugvolumen des Ansauganschlusses bedarfsweise auf den Bodenbereich des Teiches und die Wasseroberfläche verteilt werden kann.With the pond pump according to the invention can now be placed on the intake manifold on the pond pump, which ends in the upper part of a water level, so that water can be sucked from this area, wherein the intake volume of the intake port, if necessary, distributed to the bottom portion of the pond and the water surface can be.

Ein weiterer Vorteil der vorliegenden Erfindung ist, dass der Ansaugstutzen zwischen einer ersten Endposition und einer zweiten Endposition verstellbar ist, wobei in der ersten Endposition der Anteil des Ansaugvolumens am Ansaugstutzen 100% und am Ansaugbereich 0% beträgt und in der zweiten Endposition der Anteil des Ansaugvolumens am Ansaugstutzen 0% und am Ansaugbereich 100% beträgt.Another advantage of the present invention is that the intake manifold between a first end position and a second end position is adjustable, wherein in the first end position, the proportion of the intake volume at the intake 100% and 0% at the intake and in the second end position, the proportion of the intake volume at the intake port 0% and at the intake is 100%.

Durch diese Einstellbarkeit des Ansaugvolumens ist es möglich, Wasser entweder nur von der Wasseroberfläche oder nur vom Bodenbereich anzusaugen oder aber das Ansaugvolumen zwischen diesen Extremstellungen aufzuteilen.Due to this adjustability of the intake volume, it is possible to suck in water either only from the water surface or only from the bottom area or to divide the intake volume between these extreme positions.

Ein weiterer Vorteil besteht darin, dass der Ansaugstutzen und der Ansauganschluß mit einer Längsachse in einer Ebene angeordnet sind und der Ansaugstutzen um eine senkrecht zu der Längsachse stehende Drehachse zwischen der ersten Endposition und der zweiten Endpositon drehbar ist.Another advantage is that the intake manifold and the intake port are arranged with a longitudinal axis in a plane and the intake manifold is rotatable about a rotational axis perpendicular to the longitudinal axis between the first end position and the second Endpositon.

Durch diese Maßnahme kann die Teichpumpe in einer sehr kompakten Weise gebaut werden. Durch die Verdrehung des Ansaugstutzens läßt sich die Einstellung des Ansaugvolumens auch von außen optisch erkennen.By this measure, the pond pump can be built in a very compact manner. Due to the rotation of the intake, the setting of the intake volume can also be visually recognized from the outside.

In diesem Zusammenhang ist ein weiterer Vorteil, dass die Längsachsen des Ansauganschlusses und des Ansaugstutzens in der ersten Endposition zusammenfallen und in jeder anderen Position zwischen der ersten Endposition und der zweiten Endposition einen Winkel einschließen.In this context, another advantage is that the longitudinal axes of the suction port and the intake manifold coincide in the first end position and enclose an angle in any other position between the first end position and the second end position.

Wenn der Druckanschluß ebenfalls einen Druckstutzen zum Anschließen einer Druckleitung aufweist, was regelmäßig der Fall ist, verändert sich auch die Winkelposition zwischen dem Druckstutzen und dem Ansaugstutzen um den Verstellwinkel. So dass die Einstellung auch aus der Entfernung optisch wahrnehmbar ist.If the pressure connection also has a pressure port for connecting a pressure line, which is the case regularly, the angular position between the pressure port and the intake manifold also changes by the adjustment angle. So that the setting is visually noticeable even from a distance.

Weitere Vorteile ergeben sich aus den Merkmalen der weiteren Unteransprüche.Further advantages emerge from the features of the further subclaims.

In Fig. 1 ist schematisch eine Teichpumpe 1 dargestellt. Die Teichpumpe 1 weist ein Gehäuse 3 auf, dessen obere Gehäuseschale als Filterdeckel 3.1 ausgebildet ist. Der Filterdeckel 3.1 weist kleine Öffnungen oder Schlitze 3.2 auf, die als Grobfilter dienen. Aus dem Umfang des Gehäuses 3 stehen ein Druckstutzen 5 und ein Ansaugstutzen 7 vor.In Fig. 1 schematically a pond pump 1 is shown. The pond pump 1 has a housing 3, the upper housing shell is designed as a filter cover 3.1. The filter cover 3.1 has small openings or slots 3.2, which serve as a coarse filter. From the periphery of the housing 3 are a discharge nozzle 5 and an intake 7 before.

In Fig. 2 ist die Teichpumpe aus Fig. 1 ohne Filterdeckel 3.1 dargestellt. Im Inneren des Gehäuses 3 ist eine Pumpeinrichtung 9 angeordnet, die von üblicher Bauart ist und hier nicht weiter beschrieben wird. Im hinteren Teil der unteren Hälfte des Gehäuses 3, der sogenannten Unterschall, sind ebenfalls kleine Öffnungen oder Schlitze 3.2 als Grobfilter ausgebildet. Durch diese Öffnungen oder kleinen Schlitze 3.2 kann auch Wasser aus einem Teich angesaugt werden, so dass diese Öffnungen und kleinen Schlitze 3.2 an dem Gehäuse 3 einen Ansaugbereich bilden, der im Folgenden als Synonym auch das Bezugszeichen 3.2 zugewiesen bekommt. Hinter der Pumpeinrichtung 9 ist ein Elektromotor 11 wasserdicht angeordnet.In Fig. 2 is the pond pump off Fig. 1 shown without filter cover 3.1. Inside the housing 3, a pumping device 9 is arranged, which is of conventional design and will not be described further here. In the rear part of the lower half of the housing 3, the so-called subsonic, also small openings or slots 3.2 are formed as a coarse filter. Through these openings or small slots 3.2 and water can be sucked from a pond, so that these openings and small slots 3.2 on the housing 3 form a suction, which also gets the reference number 3.2 assigned as synonymous below. Behind the pumping device 9, an electric motor 11 is arranged waterproof.

In Fig. 3 ist schematisch eine Draufsicht der Teichpumpe 1 ohne Filterdeckel 3.1 dargestellt. In dem Gehäuse 3 ist in Fluidkommunikation mit der Pumpeinrichtung 9 ein Ansauganschluß 17 ausgebildet. In einem Winkel zu dem Ansauganschluß 17, vorzugsweise senkrecht zu dem Ansauganschluß 17, ist ein Druckanschluß 15 mit dem Druckstutzen 5 ausgebildet. Der Ansauganschluß 17 und der Druckanschluß 15 weisen jeweils eine Längsachse auf, die in der vorliegenden Ausführungsform in einer gemeinsamen Ebene liegen. In einer Betriebsposition der Teichpumpe 1 ist diese gemeinsame Ebene vorzugsweise eine horizontale Ebene. In anderen Ausführungsformen kann diese Ebene aber auch eine in Betriebsposition vertikale Ebene oder eine Ebene zwischen einer horizontalen und einer vertikalen Ebene sein. Es ist auch denkbar, dass die beiden Längsachsen des Ansauganschlusses 17 und des Druckanschlusses 15 nicht in einer gemeinsamen Ebene liegen.In Fig. 3 schematically a plan view of the pond pump 1 without filter cover 3.1 is shown. In the housing 3, a suction port 17 is formed in fluid communication with the pumping device 9. At an angle to the suction port 17, preferably perpendicular to the suction port 17, a pressure port 15 is formed with the discharge port 5. The suction port 17 and the pressure port 15 each have a longitudinal axis, which lie in the present embodiment in a common plane. In an operating position of the pond pump 1, this common plane is preferably a horizontal plane. In other embodiments, however, this plane may also be an operating plane vertical plane or a plane between a horizontal and a vertical plane. It is also conceivable that the two longitudinal axes of the suction port 17 and the pressure port 15 are not in a common plane.

Der Ansaugstutzen 7 ist in Bezug zu dem Ansauganschluß 17 verstellbar in dem Gehäuse 3 angeordnet. In Fig. 3 befindet sich der Ansaugstutzen 7 in einer zweiten Endposition, welche den Ansaugstutzen 7 aus einer Fluidkommunikation mit dem Ansauganschluß 17 bringt. Es besteht also keine Fluidverbindung zwischen dem Ansaugstutzen 7 und dem Anschluß 17. In dieser Position saugt der Ansauganschluß 17 100% seines Ansaugvolumens durch den Ansaugbereich bzw. die Schlitze 3.2 des Filterdeckels 3.1 bzw. der Unterschale an. Der Ansaugstutzen 7 kann stufenlos oder über Zwischenstellungen in die in Fig. 4 dargestellte Endposition gebracht werden. In der in Fig. 4 dargestellten Endposition saugt die Pumpeinrichtung 9 100% des Ansaugvolumens über den Ansauganschluß 17 und den Druckstutzen 7 an. In dieser ersten Endposition in Fig. 4 wird kein Wasser durch den Ansaugbereich 3.2 angesaugt.The intake manifold 7 is adjustably arranged in the housing 3 with respect to the intake port 17. In Fig. 3 is the intake manifold 7 in a second end position, which brings the intake manifold 7 from a fluid communication with the suction port 17. Thus, there is no fluid connection between the intake 7 and the port 17. In this position, the suction port 17 sucks 100% of its intake through the intake or the slots 3.2 of the filter cover 3.1 and the lower shell. The intake 7 can be stepless or via intermediate positions in the in Fig. 4 shown end position are brought. In the in Fig. 4 illustrated end position sucks the pumping device 9 100% of the intake volume via the suction port 17 and the discharge port 7. In this first end position in Fig. 4 no water is sucked through the intake area 3.2.

In Fig. 3 und Fig. 4 ist dargestellt, daß der Ansaugstutzen 7 auf einer Kreisbahn um eine Drehachse drehbar ist, die senkrecht auf der Längsachse des Ansaugstutzen 7 steht. Mit der Verstellung des Ansaugstutzen 7 in eine wahlfreie Zwischenstellung zwischen der ersten Endposition in Fig. 4 und der zweiten Endposition in Fig. 3 kann das Ansaugvolumen der Pumpeinrichtung 9 auf den Ansaugstutzen 7 und auf die Schlitze 3.2 des Filterdeckels 3.1 verteilt werden.In FIG. 3 and FIG. 4 It is shown that the intake manifold 7 is rotatable on a circular path about an axis of rotation which is perpendicular to the longitudinal axis of the intake manifold 7. With the adjustment of the intake manifold 7 in an optional intermediate position between the first end position in Fig. 4 and the second end position in Fig. 3 the suction volume of the pumping device 9 can be distributed to the intake manifold 7 and to the slots 3.2 of the filter cover 3.1.

Durch die wahlfreie Positionierung des Ansaugstutzens 7 in Bezug zum Ansauganschuß 17 kann das Ansaugvolumen der Pumpeinrichtung 9 über den Ansaugstutzen zwischen 0% und 100% eingestellt werden. Die jeweilige Differenz des Ansaugvolumens auf 100% wird dann über den Ansaugbereich 3.2 geliefert.By the optional positioning of the intake manifold 7 with respect to the Ansauganschuß 17, the intake volume of the pumping device 9 can be adjusted via the intake between 0% and 100%. The respective difference of the intake volume to 100% is then supplied via the intake area 3.2.

In Fig. 5 ist die erfindungsgemäße Teichpumpe schematisch und perspektivisch von der Seite aus zu sehen. Auf der rechten Seite in Fig. 5 sind die Ansaugschlitze 3.2 bzw. der von diesen gebildete Ansaugbereich 3.2 dargestellt.In Fig. 5 the pond pump according to the invention is to be seen schematically and in perspective from the side. On the right in Fig. 5 the intake slots 3.2 and the intake area 3.2 formed by these are shown.

In Fig. 6 ist eine Draufsicht der Teichpumpe 1 aus Fig. 5 dargestellt Die Draufsicht aus Fig. 6 ist etwas detaillierter als die Draufsichten aus Fig. 3 und Fig. 4. Der Ansaugstutzen 7 kann auch stufenweise verstellbar sein. Dafür sind in Fig. 6 Rastpunkte 19 ausgebildet, an denen der Ansaugstutzen 7 positioniert werden kann. Der Ansaugstutzen 7 weist ein Gewinde 21, vorzugsweise ein Außengewinde, auf, an dem eine Saugleitung angeschlossen werden kann. Die Pumpeinrichtung kann mit einer Frostschutzeinrichtung (nicht dargestellt) versehen sein, die sie vor einem Einfrieren schützt.

An dem Ansaugstutzen 7 ist eine Ansaugleitung 37 angebracht, die zu einem Skimmer 47 im Bereich der Wasseroberfläche des Teiches führt. Je nach Positionierung des Ansaugstutzens 7 in Bezug zum Ansauganschluß 17 kann die Ansaugung von Bodenschmutz wahlweise zwischen 0 und 100% der gesamten Pumpenleistung variiert werden. Entsprechend kann die Ansaugung von Oberflächenschmutz wahlweise zwischen 0 und 100% variiert werden. So ist es z.B. möglich, über eine Zwischenpositionierung des Ansaugstutzens 7 in Bezug zum Anschluß 17 70% der gesamten Pumpenleistung auf den Ansaugbereich 3.2 zu richten und entsprechend Bodenschmutz anzusaugen und 30% der gesamten Pumpenleistung auf den Ansaugstutzen 7 zu richten und entsprechend Oberflächenschmutz anzusaugen.In Fig. 7 a system sketch is shown that shows a pond cross section. At the bottom of the illustrated pond, the pond pump 1 according to the invention is positioned. At the discharge nozzle 5, a pressure line 35 is attached, which leads to a pond filter outside the pond. At the intake manifold 7, a suction pipe 37 is attached, which leads to a skimmer 47 in the region of the water surface of the pond. Depending on the positioning of the intake manifold 7 with respect to the intake port 17, the intake of soil dirt can optionally be varied between 0 and 100% of the total pump power. Accordingly, the suction of surface dirt can be optionally varied between 0 and 100%. Thus, it is possible, for example, to direct an intermediate positioning of the intake 7 with respect to the terminal 17 70% of the total pump power to the intake 3.2 and suck in accordance soil pollution and to direct 30% of the total pump power to the intake 7 and suck in accordance with surface dirt.
