Definitions

  • the invention relates to a flushing device for a water closet according to the preamble of claim 1.
  • Conventional cisterns have a float valve as a drain valve, which is opened to trigger a flush, for example by pressing a button.
  • the cistern is located above the toilet bowl to be flushed, and when the float valve is opened, the flushing water flows through a flushing pipe into the toilet bowl due to the force of gravity.
  • flushing devices are known in which the rinse water is placed in the cistern under pressure. When rinsing the rinse water leaves the cistern with increased energy due to the increased pressure and accordingly the rinsing effect is greater.
  • the US-A-5,005,226 revealed in the FIGS. 1 to 6 a cistern of the type mentioned.
  • the outlet valve has a closure body, which can be raised to Spülauslect with a hydraulic actuator.
  • a piston which is sealed with a rolling diaphragm moves downward under the action of a spring and thus displaces the water present in the pressure cylinder unit.
  • the piston is raised to a stop by inflowing water and at the same time the said spring is tensioned.
  • the WO 98/39522 a cistern with a pressure vessel having a bottom with a purge valve.
  • Water is introduced into the spherical pressure vessel to prepare a flush from a supply line.
  • the pressure vessel air is supplied. This air is compressed when the water is introduced and builds up a pressure in the container. If the purge valve is opened, the water flows out of the pressure vessel due to the expanding air and due to the gravitational force through the open flush valve in the toilet bowl. Due to the increased rinsing effect can be rinsed with less water.
  • a disadvantage of this flushing device that it must be designed for a relatively high pressure and that it is difficult to adjust the appropriate pressure in the container.
  • the WO 95/04196 discloses a flushing device having a cistern with two water outlets. As usual, water is introduced into the toilet bowl through the one spout for rinsing. The other outlet is connected to a nozzle which is placed in a siphon of the toilet bowl and which, when rinsing, should accelerate the water of the siphon. The rinse water is not pressurized in this flushing device.
  • a flushing device with two outlets and a nozzle in the siphon is relatively expensive and is not suitable in all cases.
  • the invention has for its object to provide a flushing device of the type mentioned, in which the flushing amount and the pressure of the pressure piston on the rinse water at a flush are precisely defined.
  • the problem is solved according to claim 1.
  • the inventive flushing device is not compressed air, but a spring tensioned. This has the significant advantage that the flushing power can be easily optimized by appropriate adjustment of the spring or by additional weights and adapted to special toilet bowls.
  • the pressure piston is locked in a starting position and can be unlocked for a rinsing release. This results in a precise defined flushing volume and a defined pressure of the pressure piston on the rinse water at a rinse.
  • the pressure piston can be unlocked mechanically, pneumatically or electrically.
  • the pressure cylinder unit receives substantially all of the rinse water.
  • a pressure cylinder unit can be integrated very space-saving in a box body. It is preferably provided that the pressure cylinder unit is at least partially formed by an outer wall of the Spülkasten stressess. This allows a particularly space-saving and cost-effective production.
  • the outlet valve is a servo valve.
  • Such a can according to a development of the invention comprise a membrane which closes the valve under water pressure. This allows a flushing substantially without closing noise.
  • a flushing can be triggered by an actuation of this element.
  • a release is relatively simple and can be done mechanically, pneumatically or electrically.
  • the flushing device has two pressure cylinders which are arranged in the flushing cistern, so-called dual flushing is possible. In a small flush only one of the two pressure cylinder units is emptied. For a full flush both pressure cylinder units are emptied simultaneously. In both cases, the amount of rinse water is precisely defined.
  • the flushing water amount of the two pressure cylinder units may be the same or different.
  • the flushing device has a cistern 1, which has a box body 2 preferably made of plastic.
  • This box body 2 has a top wall 2a, a bottom wall 2b and a jacket 2c.
  • an inspection opening 10 is arranged, which, however, can also be arranged in the top wall 2a.
  • an outlet connection 21 which is connected to a toilet bowl, not shown here.
  • the spout 21 leads horizontally in the toilet bowl.
  • two pressure cylinder units 8 and 9 are arranged, each having a piston 11 and 12 respectively.
  • the pistons 11 and 12 are each vertical in a pressure chamber 14 and 15, respectively displaceable and sealed with sealing rings 13 against a cylinder wall 41 and 42, respectively.
  • These walls 41 and 42 each have a bottom 18 and 19, in which a passage 16 and 17 is arranged.
  • These passages 16 and 17 lead into a common space 20 in which an outlet valve 27 is arranged.
  • the outlet valve 27 is a servo valve and has as closure body a bellows 44 of a flexible membrane.
  • the bellows 44 cooperates with a valve seat 43, which is arranged on the outlet connection 21.
  • the bellows 44 is connected to a vent passage 33 which is vented by means of a vent member 31.
  • a closure element 34 is raised against the retroactive force of a spring 35 by a valve seat 36 of the ventilation channel 33. This can be done according to Fig. 5 done with a cable 45.
  • the closure body 34 can be lifted pneumatically or with an electric drive. Also conceivable is a remote release.
  • the bellows 44 forms an interior space 40 which is permanently connected to the space 20 via a passage 28.
  • the space 40 is via a water pipe 7 according to Fig. 7 connected to an inlet valve 6, which is preceded by a regulating valve 5.
  • This regulating valve 5 is connected to a supply line 4.
  • the inlet valve 6 is open, the interior 40 is connected to the supply line 4.
  • the pistons 11 and 12 are each provided on the upper side with a pin 23 which is directed vertically upwards and cooperates with a holder 24 for locking the piston 11 and 12, respectively.
  • the brackets 24 each have a bearing 25 on which locking means 26 are mounted. With this locking means 26, the pistons 11 and 12 in the in FIG. 4 shown upper starting position are releasably locked.
  • the locking means 26 are formed so that the pistons 11 and 12 are automatically locked upon reaching the starting position.
  • the release of the locking takes place by means of an unlocking device 30, which is in engagement with the locking members 26.
  • the unlocking takes place, for example, by a horizontal movement of a locking pin 26a against the retroactive force of a spring 26b.
  • a compression spring 22 is supported in each case, which abuts at a lower end on the piston 11 and 12 respectively. If the piston 11 or 12 in the in Fig. 5 raised lower position shown, the corresponding spring 22 is tensioned. When the upper position is reached, the piston 11 or 12 is automatically locked.
  • the Fig. 4 shows the cistern 1 in the starting position.
  • the two pressure chambers 14 and 15 are filled with rinse water.
  • the springs 22 are cocked and the pistons 11 and 12 are locked in an upper home position.
  • the outlet valve 27 and the vent valve 31 are closed. Closed is also the inlet valve. 6
  • the unlocking device 30 is activated so that the latch 26a of the pressure cylinder unit 8 is moved and thus the piston 11 is unlocked.
  • the piston 11 is thereby released and loaded by the force of the spring 22.
  • the cable 45 of the Shutter body 34 of the vent valve 31 is raised.
  • the pressure in the chamber 40 decreases and due to the pressure difference to the chamber 20, the bellows 44 lifts off from the valve seat 43.
  • the water in the chamber 20 can thus flow through the outlet nozzle 21 into the flushing pipe, not shown.
  • the flushing device has as explained the advantage that it can be optimized and adapted to special toilet bowls.
  • the springs 22 can be replaced by stronger or weaker springs.
  • the piston 11 and 12 according to Fig. 5 For example, annular weights 47 are placed. Such weights 47 increase the pressure of the water in the pressure chambers 14 and 15 and accordingly these pressure chambers 14 and 15 are emptied at a higher pressure flush and correspondingly faster.
  • the regulating valve 5 is adapted to this changed system pressure.
