Definitions

  • the present invention relates to a pond pump with a housing, with a suction connection, to which a suction area of a housing shell formed with through slots is assigned, with a pressure connection, which is in fluid communication with the suction connection via a pump device arranged in the housing, with a motor for Driving the pump device and with a control device for controlling the pump device and the motor.
  • Such pond pumps are generally known in the prior art. They are positioned on 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 the housing, but not leaves, small branches and other coarse particles.
  • the water is sucked through a pump direction arranged in the housing into a suction connection lying behind the coarse filter bowl and is pressed via a pressure connection into a pressure line which releases the water at a free end.
  • pond pumps only water from the bottom area of the pond or basin is sucked in for regular cleaning. With such a pump it is not possible to draw water from the pond surface in order to clean it too.
  • the object of the present invention is to create a pond pump with which water can be freely selected from the floor area for a given suction volume. a pond or basin and / or from the surface of the water.
  • the object is achieved according to the invention by additionally assigning an intake port to the intake port, which is arranged so as to be adjustable with respect to the intake port, in such a way that an intake volume of the intake port can be divided between the intake port and the intake area.
  • the intake port is adjustable between a first end position and a second end position, the proportion of the intake volume in the intake port being 100% in the first end position and 0% in the intake area and the proportion of the intake volume in the second end position is 0% at the intake and 100% at the intake area.
  • This adjustability of the suction volume makes it possible to draw water either only from the water surface or only from the floor area or to divide the suction volume between these extreme positions.
  • the intake port and the intake port are arranged in one plane with a longitudinal axis and the intake port is rotatable about an axis of rotation perpendicular to the longitudinal axis between the first end position and the second end position.
  • the pond pump can be built in a very compact manner.
  • the setting of the intake volume can also be seen from the outside.
  • another advantage is that the longitudinal axes of the intake port and the intake port . collapse in the first end position and enclose an angle in any other position between the first end position and the second end position. If the pressure connection also has a pressure connection for connecting a pressure line, which is regularly the case, the angular position between the pressure support and the intake connection also changes by the adjustment angle. So that the setting can be seen from a distance.
  • Fig. 1 is a schematic, perspective view of a pond pump, in which an upper housing shell designed as a filter cover, a pressure port and an adjustable suction port according to the present invention is shown.
  • FIG. 2 shows a schematic, perspective view of the pond pump from FIG. 1 with the filter cover removed;
  • FIG. 3 shows a schematic top view of the pond pump from FIG. 2, with the filter cover removed, in a second end position, in which the suction nozzle is not in fluid communication with the suction connection and the suction takes place exclusively via a suction area of the housing;
  • FIG. 4 shows a schematic top view of the pond pump from FIG . 2, with the filter cover removed, in a first end position, in which the intake port is in full fluid communication with the intake port and the intake takes place exclusively via the intake port;
  • FIG. 5 shows a schematic, perspective side view of the pond pump according to the invention with the filter cover removed;
  • FIG. 6 shows a schematic top view of the pond pump from FIG. 5;
  • Fig. 7 is a schematic sectional view through a typical garden pond, with the pond pump according to the invention set up on the bottom, to show the two locally removed suction points on the pond bottom and on the water surface.
  • a pond pump 1 is shown schematically.
  • the pond pump 1 has a housing 3, the upper housing shell of which 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 circumference of the housing 3, a pressure port 5 and an intake port 7 protrude.
  • Fig. 2 the pond pump from Fig. 1 is shown without filter cover 3.1.
  • a pump device 9 is arranged, which is of conventional design and is not described further here.
  • small openings or slots 3.2 are also formed as coarse filters. Through these openings or small slots 3.2, water can also be sucked out of a pond, so that these openings and small slots 3.2 form a suction area on the housing 3, which in the following is also assigned the reference symbol 3.2 as a synonym.
  • An electric motor 11 is arranged watertight behind the pump device 9.
  • FIG. 3 a top view of the pond pump 1 without filter cover 3.1 is shown schematically.
  • An intake port 17 is formed in the housing 3 in fluid communication with the pump device 9.
  • a pressure connection 15 with the pressure connection 5 is formed at an angle to the suction connection 17, preferably perpendicular to the suction connection 17.
  • the suction connection 17 and the pressure connection 15 each have a longitudinal axis which lie in a common plane in the present embodiment. In an operating position of the pond pump 1, this common plane is preferably a horizontal plane. In other versions However, this level can also be a vertical level in the operating position or a level between a horizontal and a vertical level. It is also conceivable that the two longitudinal axes of the intake wrench 17 and the pressure connection 15 are not in a common plane.
  • the intake port 7 is arranged adjustable in the housing 3 with respect to the intake port 17.
  • the intake port 7 is in a second end position, which brings the intake port 7 out of fluid communication with the intake port 17. There is therefore no fluid connection between the suction nozzle 7 and the connection 17.
  • the suction connection 17 sucks 100% of its suction volume through the suction area or the slots 3.2 of the filter cover 3.1 or the lower shell.
  • the intake manifold 7 can be brought into the end position shown in FIG. 4 continuously or via intermediate positions.
  • the pump device 9 sucks 100% of the suction volume via the suction connection 17 and the pressure port 7.
  • no water is drawn in through the suction area 3.2.
  • 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.
  • the suction volume of the pump device 9 can be distributed over the suction nozzle 7 and over the slots 3.2 of the filter cover 3.1.
  • the intake volume of the pump device 9 can be set between 0% and 100% via the intake port.
  • the respective difference in the intake volume to 100% is then supplied via the intake area 3.2.
  • the pond pump according to the invention can be seen schematically and in perspective from the side. On the right side in FIG. 5, the suction slots 3.2 or the suction area 3.2 formed by them are shown.
