Definitions

  • the invention relates to a drain valve for a cistern, especially toilet cistern, with one on the cistern floor to be attached housing in which a float with an air chamber open at the bottom, which Float on a locking device that is lifted in the housing is attached and an upper ceiling wall and a Has side wall.
  • a drain valve is known from DE-U-93 11 189.
  • Drain valves of this type have been known for a long time. With these is the buoyancy of the float after a flush has been triggered by the existing in an air chamber of the swimmer Air guaranteed. Such drain valves can be designed in this way be that an early interruption of the flushing is possible. Drain valves are also known allow a so-called two-stage rinse. When actuated the cistern is then automatically complete with a button emptied. When you press another key is also automatically only a part of the in the cistern existing flushing water volume, for example 6 liters. Practice has shown that such a two-stage rinse with precisely set amounts of rinse water from User to consider rinsing interruption to be determined is. With two-stage flushing, there is an optimal saving of rinse water possible if the small amount of rinse water is always exactly the same for small flushes.
  • the inventor has now determined through extensive investigations that with small flushes when using generic Drain valves escape from the air float and thereby get water into the float from below can. As a result, the buoyancy of the swimmer and thereby changing the flushing water quantity in an uncontrolled manner. The consequence of it is that with the small rinses either too much or too little water is released.
  • the inventor has now set the task of a drain valve of the above Genre to create that more precisely with small flushing works and yet not much more complex and is more expensive to manufacture.
  • the task is therefore in a generic drain valve solved that the side wall of the air chamber in one distance from the ceiling wall determined by the volume of air has at least one ventilation opening in such a way that when the cistern is full there is a layer of water below the ventilation opening which prevents air from being sucked out of the float during a small flush.
  • the solution is surprisingly simple, yet reliable.
  • the drain valve according to the invention after each Flush the float from the bottom to the vent filled with water.
  • the level of the in the swimmer existing water and thus the volume of the air chamber is always exactly determined.
  • the buoyancy is corresponding always the same for the swimmer.
  • the vent can be realized, for example, through a small hole which does not cause any significant costs.
  • the in Float existing water layer below the vent prevents from running out with a little rinse air can escape from the swimmer.
  • the drain valve 5 shown is in a known manner in one Cistern 1 over a drain opening 3 on the cistern floor 2 releasably attached.
  • a valve tube is in a valve housing 6 4 with a float 7 firmly attached to it stored liftable.
  • the opening is in the idle state shown 3 closed by a valve plate 13 of the valve tube 4. If the valve tube 4 by means of a known Actuator 14 raised, the Drain opening 3 opened and rinsing water 17 can through the window 19 of the housing 6 through the opening 3 in one here Drain the toilet bowl, not shown.
  • the valve tube 4 is caused by the buoyancy of an air chamber 16 in the housing 6 kept floating until the desired amount of rinse water is dispensed is.
  • a closing weight 15 is arranged on the valve tube 4, that loads the valve tube 4 with a small flush and brings it into the closed position prematurely. With one small rinse, the water level A of the completely filled Cistern lowered to level B. In the cistern after a small rinse there is a residual amount of water of, for example, 3 liters. With a large flush the valve tube 4 is not by the closing weight 15 charged and this remains until the complete Emptying the cistern 1 raised.
  • the float 7 has the shape of an inverted cup and has a top wall 8 and an approximately cylindrical one Side wall 9. In the lower area of the side wall 9 are at a certain distance from the ceiling 8 or more ventilation openings 10 attached.
  • This Openings 10 are comparatively small and preferably have a diameter of a few millimeters, for example 2 mm.
  • the openings 10 can also be narrow Be slots or have other shapes.
  • the float 7 has below the ventilation openings 10 a likewise cylindrical apron 11. This extends to the lower edge 12, which is the lower Opening of the float 7 defined.
  • the ventilation openings 10 are dimensioned such that this when closing briefly during a small one Flushing no air can escape. This is with a hole with a diameter of, for example, 2 to 5 mm guaranteed.
  • the ventilation openings 10 must at least be so big that after a big rinse Air in the area of the apron 11 through these openings 10 can escape and thus the water 18 in the float 7th can penetrate from below.
