Description

Die vorliegende Erfindung bezieht sich auf eine Teichpumpe. Derartige Teichpumpen weisen üblicherweise ein Gehäuse auf, wobei innerhalb des Gehäuses eine Pumpeneinrichtung vorgesehen ist, die Flüssigkeit von einem Ansaugbereich zu einem Druckanschluss transportiert. Derartige Teichpumpen werden am Boden eines Teiches oder Beckens positioniert. Das Gehäuse dieser Pumpen wirkt dabei als Grobfilter und besitzt Öffnungen, beispielsweise in Form von Schlitzen oder Löchern, durch die zwar Wasser in das Gehäuseinnere eindringen kann, nicht jedoch gröbere Verunreinigungen wie Blätter oder größere Teilchen.The present invention relates to a pond pump. Such pond pumps usually have a housing, wherein within the housing, a pump device is provided which transports liquid from a suction to a pressure port. Such pond pumps are positioned at the bottom of a pond or basin. The housing of these pumps acts as a coarse filter and has openings, for example in the form of slots or holes through which water can penetrate into the housing interior, but not coarser impurities such as leaves or larger particles.

Das durch die Gehäusewandung in das Innere des Gehäuses gelangende Wasser wird über die Pumpeneinrichtung, d. h. einen Ansauganschluss, angesaugt und über einen Druckanschluss ausgegeben. Damit gelangen jedoch kleinere Verunreinigungen durch die Öffnungen in das Gehäuseinnere und damit in den eigentlichen Pumpenkreislauf. Daher ist es in regelmäßigen Abständen erforderlich, die Pumpeneinrichtung selbst zu reinigen. Daneben ist ein weiterer Ansauganschluß vorgesehen, um Verunreinigungen von der Oberfläche des Teiches abzusaugen, wobei die Flüssigkeit nicht durch die Gehäusewandung tritt.The passing through the housing into the interior of the housing water is pumped through the pump means, d. H. a suction port, sucked and output via a pressure port. This, however, get smaller impurities through the openings in the housing interior and thus in the actual pump cycle. Therefore, it is necessary at regular intervals to clean the pump device itself. In addition, a further suction port is provided to suck contaminants from the surface of the pond, wherein the liquid does not pass through the housing wall.

Die DE 100 43 668 A1 beschreibt eine Tauchpumpe. Diese Tauchpumpe weist dabei ein erstes gesteuertes Pumpenelement und ein zweites gesteuertes Pumpenelement auf, wobei innerhalb eines Pumpengehäuses ein mit dem ersten Pumpenelement verbundener Sauganschluss ausgebildet ist, der im Betrieb Wasser aus der Umgebung der Pumpe durch einen Rundumfilter ansaugt. Daneben ist an dem Pumpengehäuse ein Sauganschluss ausgebildet, der mit dem zweiten Pumpenelement verbunden ist. Durch gezielte Ansteuerung der beiden Pumpenelemente ist es möglich, dass die Tauchpumpe in einem Arbeitsgang z.B. die Wasseroberfläche absaugen kann. Dabei weist die Pumpe einen Drucksammler und eine darin angeordnete Umschaltklappe auf, mit der die Strömungsmenge aus einem Ausgang des ersten oder zweiten Pumpenelements regelbar ist.The DE 100 43 668 A1 describes a submersible pump. This submersible pump has a first controlled pump element and a second controlled pump element, wherein within a pump housing connected to the first pump element suction port is formed, which sucks in operation water from the environment of the pump through an all-round filter. In addition, a suction port is formed on the pump housing, which is connected to the second pump element. By targeted control of the two pump elements, it is possible that the submersible pump can suck in a single operation, for example, the water surface. In this case, the pump has a pressure accumulator and a switching flap arranged therein, with which the flow rate from an output of the first or second pump element can be regulated.

Aus der DE 203 13 360 U1 ist eine Teichpumpe bekannt, die einen gegenüber dem Gehäuse beweglichen Ansaugstutzen aufweist, wobei durch die Bewegung bzw. die Stellung des Ansaugstutzens gegenüber dem Gehäuse geregelt werden kann, welcher Anteil an Wasser von der Wasseroberfläche eingesaugt wird und welcher Anteil über das Gehäuse angesaugt wird. Diese Pumpe erlaubt damit eine Einstellung der jeweiligen Strömungsverhältnisse durch eine Bewegung eines Ansaugstutzens gegenüber dem Gehäuse. Allerdings muss dabei bei der aus der DE 203 13 260 U1 bekannten Vorrichtung dafür Sorge getragen werden, dass der Verschiebebereich beziehungsweise Verschiebeschlitz, in dem der Ansaugstutzen verschoben wird, genügend abgedeckt wird, damit nicht auch grobe Verunreinigungen in das Innere des Gehäuses gelangen. Daneben ergeben sich durch die verstellbare Anordnung des Ansaugstutzens gegenüber dem Gehäuse Nachteile, da die Teichpumpe in Ihrer Gesamtheit stabiler ausgeführt werden kann.From the DE 203 13 360 U1 a pond pump is known, which has a suction port movable relative to the housing, wherein the movement or the position of the intake nozzle relative to the housing can be controlled, which proportion of water is sucked in from the water surface and which portion is sucked in via the housing becomes. This pump thus allows adjustment of the respective flow conditions by a movement of a suction nozzle relative to the housing. However, it must be in the case of the DE 203 13 260 U1 known device to ensure that the displacement or sliding slot in which the intake manifold is moved, is sufficiently covered, so that not get rough impurities in the interior of the housing. In addition, resulting from the adjustable arrangement of the intake manifold relative to the housing disadvantages, since the pond pump can be made more stable in its entirety.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Teichpumpe zur Verfügung zu stellen, mit der einerseits Wasser sowohl vom Bodenbereich eines Teiches als auch von der Wasseroberfläche angesaugt werden kann, andererseits jedoch die Stabilität der gesamten Teichpumpe erhöht wird. Genauer soll insbesondere zur Erreichung der höheren Stabilität auf schwenkbare Ansaugstutzen, die die Gesamtstabilität beeinträchtigen können, verzichtet werden.The present invention is therefore an object of the invention to provide a pond pump available, with the one hand water can be sucked both from the bottom of a pond and from the water surface, on the other hand, however, the stability of the entire pond pump is increased. In particular, to achieve the higher stability on pivoting intake manifold, which can affect the overall stability, should be dispensed with.

Dies wird erfindungsgemäß durch eine Teichpumpe durch Anspruch 1 erreicht. Vorteilhafte Ausführungsformen und Weiterbildungen sind Gegenstand der Unteransprüche.This is inventively achieved by a pond pump by claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

Die erfindungsgemäße Teichpumpe weißt ein Gehäuse sowie eine innerhalb des Gehäuses angeordnete Pumpeneinrichtung auf. Weiterhin ist ein Ansauganschluss vorgesehen und ein Druckausgang, wobei der Ansauganschluss und der Druckausgang miteinander in Fluidverbindung stehen und wobei der Ansauganschluss in wenigstens zwei im Wesentlichen voneinander getrennte Ansaugkanäle mündet. Dabei ist der erste Ansaugkanal zum Ansaugen von Flüssigkeit durch die Gehäusewand hindurch geeignet und der zweite Ansaugkanal zum Ansaugen außerhalb des Gehäuses befindlicher Flüssigkeit.The pond pump according to the invention has a housing and a pump device arranged within the housing. Furthermore, a suction port is provided and a pressure outlet, wherein the suction port and the pressure outlet are in fluid communication with each other and wherein the suction port opens into at least two substantially separate suction channels. In this case, the first intake passage for sucking liquid through the housing wall is suitable and the second intake passage for sucking liquid located outside the housing.

Erfindungsgemäß ist wenigstens der zweite Ansaugkanal fest gegenüber dem Gehäuse angeordnet und eine Strömungsverteilungseinrichtung vorgesehen, welche ein Ansaugvolumen des Ansauganschlusses auf die Ansaugkanäle aufteilt.According to the invention, at least the second intake passage is arranged fixedly in relation to the housing and a flow distribution device is provided, which divides an intake volume of the intake port into the intake passages.

Im Gegensatz zu dem oben erwähnten Stand der Technik ist damit der Ansaugkanal fest gegenüber dem Gehäuse wodurch die Stabilität erhöht wird. Vorzugsweise sind beide Ansaugkanäle fest gegenüber dem Gehäuse. Die Pumpeneinrichtung ist vorteilhaft mit einem Motor sowie einer Steuerungseinrichtung versehen. Der erste Ansaugkanal endet bevorzugt im Inneren des Gehäuses und damit wird durch diesen Ansaugkanal Flüssigkeit durch das Gehäuse bzw. die Gehäusewand hindurch angesaugt.In contrast to the above-mentioned prior art, so that the intake passage fixed to the housing whereby the stability is increased. Preferably, both intake ports are fixed relative to the housing. The pump device is advantageously provided with a motor and a control device. The first intake passage preferably ends in the interior of the housing and thus liquid is sucked through the housing or the housing wall through this intake passage.

Unter einer Strömungsverbindung zwischen dem Ansauganschluss und dem Druckausgang wird verstanden, dass ein Fluid und insbesondere Wasser zwischen dem Ansauganschluss und dem Druckausgang fließen kann.A flow connection between the suction port and the pressure outlet means that a fluid and in particular water can flow between the suction port and the pressure outlet.

In einer weiteren bevorzugten Ausführungsform ist der zweite Ansaugkanal ein Ansaugstutzen, der sich wenigstens abschnittsweise durch das Gehäuse hindurch erstreckt. Auf diese Weise wird gewährleistet, dass der zweite Kanal ausschließlich Flüssigkeit von außerhalb des Gehäuses ansaugt. Weiterhin wäre es möglich, in dem zweiten Ansaugkanal Filterelemente wie Feinfilter vorzusehen.In a further preferred embodiment, the second intake passage is an intake port which extends through the housing at least in sections. In this way, it is ensured that the second channel only sucks in liquid from outside the housing. Furthermore, it would be possible to provide filter elements such as fine filters in the second intake channel.

Es wäre jedoch auch möglich, dass der zweite Ansaugkanal zwar noch im Inneren des Gehäuses endet, aber eine Kupplung oder dergleichen aufweist, an welche ein Schlauch aufgesteckt werden kann, der seinerseits bezüglich des Gehäuses nach außen ragt.However, it would also be possible for the second intake duct to still end inside the housing, but to have a coupling or the like, to which a hose can be plugged, which in turn projects outward with respect to the housing.

Auch wären Ansaugkanäle denkbar, die mit bzw. in der Gehäusewandung enden. Der Ansauganschluss ist bevorzugt direkt an der Pumpeneinrichtung angeordnet.Also, intake ducts would be conceivable that end with or in the housing wall. The suction port is preferably arranged directly on the pump device.

In einer weiteren bevorzugten Ausführungsform ist die Strömungsverteilungseinrichtung zwischen dem Ansauganschluss und den Ansaugkanälen vorgesehen. Diese Strömungsverteilungseinrichtung verteilt damit das Strömungsvolumen auf die hier vorgesehenen beiden Ansaugkanäle. Damit ist nur die Strömungseinrichtung bzw. Teile der Strömungsverteilungseinrichtung bewegbar, nicht jedoch die Ansaugkanäle selbst.In a further preferred embodiment, the flow distribution device is provided between the suction port and the intake ports. This flow distribution device thus distributes the flow volume to the two intake channels provided here. Thus, only the flow device or parts of the flow distribution device is movable, but not the intake channels themselves.

Vorzugsweise sind die Ansaugkanäle im wesentlichen senkrecht zueinander angeordnet. Aus diese Weise kann eine besonders günstige Strömungsverteilung zwischen den Ansaugkanälen erreicht werden.Preferably, the intake passages are arranged substantially perpendicular to each other. In this way, a particularly favorable flow distribution between the intake ports can be achieved.

Vorteilhaft weist das Gehäuse Öffnungen auf, durch welche hindurch Flüssigkeit in das Gehäuseinnere eintreten kann. Durch diese Öffnungen gelangt die Flüssigkeit zu dem ersten Ansaugkanal.Advantageously, the housing has openings through which liquid can enter the interior of the housing. Through these openings, the liquid passes to the first intake passage.

Besonders bevorzugt sind in demjenigen Bereich des Gehäuses, in dem der erste Ansaugkanal angeordnet ist, keine Öffnungen vorgesehen. Auf diese Weise kann erreicht werden, dass die Flüssigkeit innerhalb des Gehäuses einen gewissen Weg zurücklegen muss, um bis zu dem ersten Ansaugkanal zu gelangen. Aber auf diese Weise können gewisse grobe Verunreinigungen, die noch durch die Öffnungen hindurchgetreten sind, von einem Eintritt in den zweiten Ansaugkanal abgehalten werden. Weiterhin werden durch diese Ausführungsform die Strömungsverhältnisse verbessert, da die Flüssigkeit über das gesamte Gehäuse gleichmäßiger angesaugt wird.Particularly preferably, no openings are provided in the region of the housing in which the first intake passage is arranged. In this way it can be achieved that the liquid within the housing has to travel a certain distance in order to reach the first intake channel. But in this way certain coarse contaminants which have still passed through the openings can be prevented from entering the second intake channel. Furthermore, the flow conditions are improved by this embodiment, since the liquid is sucked uniformly over the entire housing.

In einer weiteren bevorzugten Ausführungsform weist die Strömungsverteilungseinrichtung einen außerhalb des Gehäuses angeordneten Betätigungsmechanismus auf, mit dem die Aufteilung des Ansaugvolumens auf die Ansaugkanäle gesteuert werden kann. Dabei kann es sich beispielsweise um einen Drehknopf oder dergleichen handeln, der einen Ventilkörper zwischen zwei Endpositionen hin- und herbewegen kann. Es wäre jedoch auch möglich, die Strömungsverteilungseinrichtung durch einen zusätzlichen Bewegungsmotor beispielsweise im Inneren des Gehäuses zu steuern. Auf diese Weise wäre in einer besonders komfortablen Ausführungsform eine Fernsteuerung der Strömungsverteilungseinrichtung möglich. Daneben könnte auch ein Ventilkörper vorgesehen sein, der beispielsweise mittels einer Gewindestange verschiebbar ist.In a further preferred embodiment, the flow distribution device has an actuating mechanism arranged outside the housing with which the distribution of the intake volume onto the intake passages can be controlled. This may be, for example, a knob or the like, which can reciprocate a valve body between two end positions. However, it would also be possible to control the flow distribution device by an additional motor, for example, inside the housing. In this way, in a particularly convenient embodiment, a remote control of the flow distribution device would be possible. In addition, a valve body could be provided which is displaceable, for example by means of a threaded rod.

Bei einer bevorzugten Ausführungsform weist die Strömungsverteilungseinrichtung einen drehbaren Ventilkörper auf, mit dem die Aufteilung des Ansaugvolumens auf die Ansaugkanäle gesteuert werden kann. Dabei steht besonders bevorzugt die Strömungsverteilungseinrichtung in Verbindung mit dem Betätigungsmechanismus und ist damit manuell verstellbar. Dieser Ventilkörper ist dabei bevorzugt in dem Bereich angeordnet, in dem der Ansauganschluss in die beiden Ansaugkanäle übergeht. Vorzugsweise ist der drehbare Ventilkörper um eine Längsachse des Ansauganschlusses drehbar. Auf diese Weise kann der Strömungsfluss ausgehend vom Ansauganschluss auf die beiden Ansaugkanäle verteilt werden.In a preferred embodiment, the flow distribution device has a rotatable valve body with which the distribution of the intake volume to the intake ports can be controlled. It is particularly preferred that the flow distribution device in connection with the actuating mechanism and is thus manually adjustable. This valve body is preferably arranged in the region in which the intake port merges into the two intake passages. Preferably, the rotatable valve body is rotatable about a longitudinal axis of the suction port. In this way, the flow flow can be distributed from the intake port to the two intake ports.

In einer weiteren vorteilhaften Ausführungsform ist die Strömungsverteilungseinrichtung zwischen zwei Endpositionen verstellbar, wobei in der einen Endposition das Ansaugvolumen vollständig über den ersten Ansaugkanal angesaugt wird und in der anderen Endposition das Ansaugvolumen vollständig über den zweiten Ansaugkanal angesaugt wird. Vorteilhafter Weise ist die Strömungsverteilungseinrichtung zwischen diesen beiden Endpositionen stufenlos verstellbar. Es wäre jedoch auch möglich, dass der Strömungsverteilungseinrichtung gestuft zwischen diesen beiden Endpositionen verstellbar ist.In a further advantageous embodiment, the flow distribution device is adjustable between two end positions, wherein in one end position, the intake volume is completely sucked in via the first intake passage and in the other end position the intake volume is completely sucked in via the second intake passage.
