Definitions

  • the present invention relates to a flushing system according to claim 1.
  • the WO 2016/016471 discloses a flushing system in which flushing water is brought from the cistern into the toilet bowl or urinal using a Venturi nozzle. Disadvantageous to the WO 2016/016471 is that the volume flow of the rinsing water is in some cases too small for efficient rinsing of the siphon due to the design of the Venturi nozzle.
  • the invention is based on the object of providing a flushing system which overcomes the disadvantages of the prior art.
  • a flushing system comprises a cistern with a first tank space and a second tank space, a filling valve for filling the cistern with flushing water, a first flushing valve arranged in the first tank space, a second flushing valve arranged in the second tank space, and a sanitary article with a receiving space, a first flushing opening, which can be supplied with flushing water via the first flushing valve, a second flushing opening, which can be supplied with flushing water via the second flushing valve, as well as a siphon section adjoining the receiving space and a drain section adjoining the siphon section.
  • the filling valve is directed into the first tank space, such that the first tank space is filled by the filling valve, and the first tank space has an overflow edge over which the flushing water flows from the first tank space when the first tank space is filled and the first tank space is filled further or continuously can be guided into the second tank room.
  • both tank spaces can be filled with a single filling valve, which makes filling the cistern more efficient.
  • the second flushing opening of the sanitary article when viewed in the installed position, is located below the overflow edge, the height of the second flushing opening defining an overflow height, which overflow height is above a nominal water level in the second tank space.
  • the overflow edge is located in such a way that the flushing water flows over the overflow edge, that is to say, flows out over the overflow edge above the overflow edge.
  • the nominal water level in the first tank space is above the nominal water level in the second tank space.
  • the first tank space lies entirely in the second tank space. That is, the The second tank room surrounds the first tank room on its outside. This has the advantage that the length of the overflow edge can be made as large as possible, which allows the second tank space to be filled efficiently.
  • the volume of the first tank space is smaller than the volume of the second tank space.
  • the first flushing valve and the first flushing opening are designed such that the flushing water can be introduced into the drain section and the second flushing valve and the second flushing opening are designed such that the flushing water can be introduced into the receiving space.
  • a surge-like flushing can be provided into the drain section via the gravity flushing valve, which creates a suction effect on the siphon section and can support the flushing of the siphon.
  • the surfaces of the receiving space can be flushed using the pressure flushing valve.
  • the first flushing valve is preferably opened after the second flushing valve and/or the first flushing valve is closed before the second flushing valve.
  • the surge-like flushing through the gravity flushing valve therefore takes place over a shorter period of time than flushing via the pressure flushing valve.
  • the first flushing valve has an actuation float, wherein the actuation float floats on the flushing water in the second tank space, such that the first flushing valve can be actuated based on the water level in the second tank space. This makes it very easy to coordinate the flushing sequence.
  • the first flushing opening is arranged at the bottom of the first tank space and the first flushing valve has a valve body which can be raised from a closed position to a flushing position by a valve seat surrounding the flushing opening.
  • the first flushing opening opens into the drain section after the siphon section.
  • the second flushing valve has an inlet which is connected to a Building-side line network can be connected, such that the second flushing valve is supplied with flushing water under line pressure, the flushing valve being connected to a first section of a flushing line with a jet pump, the jet pump having a Venturi nozzle with a suction opening open towards the cistern, wherein at With an open flushing valve, water can be fed into the Venturi nozzle under line pressure, such that with the Venturi nozzle, water can be fed from the second water tank into a second section of the flushing line leading to the sanitary item via the suction opening.
  • the flushing line preferably has a pipe breaker for class separation of drinking water and flushing water.
  • the pipe interrupter When viewed in the installed position, the pipe interrupter is preferably located above the overflow edge, so that the pipe interrupter does not come into contact with the flushing water in the cistern.
  • the cistern When viewed in the installed position, the cistern is preferably located below an upper edge which closes off the sanitary item at the top.
  • the figures show a preferred embodiment of a flushing system 1 according to the present invention.
  • the flushing system 1 comprises a cistern 2 with a first tank space 3 and a second tank space 4, a filling valve 5 for filling the cistern 2 with flushing water, a first flushing valve 6 arranged in the first tank space 3, a second flushing valve 7 arranged in the second tank space 4 and a Sanitary items 8.
  • Rinsing water can be supplied to the sanitary items 8 via the flushing valves 6, 7.
  • the rinse water is preferably supplied to the sanitary article 8 at different locations.
  • the filling valve 5 is directed into the first tank space 3.
  • the filling valve 5 therefore fills the first tank space 3 with rinse water.
  • the first tank space 3 has an overflow edge 14, over which the flushing water flows from the first tank space 3 into the second tank space 4 when the first tank space 3 is filled and when the first tank space 3 is further filled.
  • the flushing system 1 is designed without an overflow edge 14.
  • the two tank spaces 3, 4 are filled in a different way using the filling valve 5.
  • the flushing valves can be provided differently.
  • the second flushing valve 7 has an inlet 18, which can be connected to a building-side pipe network, such that the second flushing valve 7 is supplied with flushing water under line pressure.
  • the flushing valve 7 is connected to a first section 19 of a flushing line with a jet pump 20, the jet pump 20 having a Venturi nozzle 21 with a suction opening 22 that is open towards the cistern 2.
  • the flushing valve 7 When the flushing valve 7 is open, water can be fed into the Venturi nozzle 21 under line pressure, such that with the Venturi nozzle 21, water from the second water tank 4 can be fed into a second section 23 of the flushing line leading to the sanitary article 8 via the suction opening 22.
  • a pipe interrupter 24 is also arranged in the flushing line.
  • the overflow edge 14 lies above the second flushing opening 11, which leads into the receiving space 9. If the filling valve is defective, water can flow into the receiving space 9 via the flushing opening 10. Above the overflow edge 14, said pipe interrupter 24 is arranged.
  • the nominal water level in the first tank room 3 is higher than the nominal water level in the second tank room 4.
  • the nominal water level in the second tank room 3 is below the second flushing opening 11.
