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
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, a suction pipe can now be attached to the pond pump, which ends in the upper part of a water level, so that water can be sucked in from this area, wherein the intake volume of the suction as needed distributed to the bottom area 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 the intake is 0% 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.

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.
