Definitions

  • the invention relates to a flushing device for a water closet, with a cistern, in which a pressure vessel is arranged, which has a supply line for water and an outlet valve and in which at least part of the flushing water can be pressurized and dispensed through the outlet valve for flushing.
  • Conventional cisterns have a float valve as an outlet valve, which is opened to trigger a flush, for example by pressing a button.
  • the cistern is arranged above the toilet bowl to be flushed and when the float valve is opened, the flushing water flows into the toilet bowl through a flushing pipe due to the gravitational force.
  • flushing devices are also known in which the flushing water is pressurized in the cistern. When flushing, the flushing water leaves the cistern with increased energy due to the increased pressure and the flushing action is accordingly greater.
  • WO 98/39522 shows a cistern with a pressure vessel that has a bottom with a flush valve.
  • Water is introduced into the spherical pressure vessel in preparation for rinsing from a supply line. Air is also supplied to the pressure vessel. This air is compressed when the water is introduced and builds up pressure in the container. If the flushing valve is opened, the water flows out of the pressure vessel due to the expanding air and due to the gravitational force through the opened flushing valve into the toilet. crisps bowl.
  • the disadvantage of this flushing device is that it has to be designed for a comparatively high pressure and that it is difficult to set the appropriate pressure in the container.
  • Applicant's WO 95/04196 discloses a flushing device which has a flushing cistern with two water outlets. Through the one spout, water is introduced into the toilet bowl as usual. The other outlet is connected to a nozzle which is arranged in a siphon in the toilet bowl and which is intended to accelerate the water of the siphon when flushing. The flushing water is not pressurized with this flushing device.
  • a flushing device with two outlets and a nozzle in the siphon is comparatively complex and is not suitable in all cases.
  • the invention has for its object to provide a flushing device of the type mentioned, which is quieter and which can be adapted to different toilet bowls.
  • the flushing device according to the invention is characterized by at least one pressure cylinder unit in which flushing water can be pressurized and can be dispensed for flushing with a spring-loaded pressure piston.
  • air is not compressed, but a spring is tensioned. This has the essential advantage that the flushing performance can be optimized in a simple manner by appropriate adjustment of the spring or by additional weights and can be adapted to special toilet bowls.
  • the pressure piston is locked in an initial position and can be unlocked for triggering a flushing. This results in an exact Defined flush volume and a defined pressure of the pressure piston on the flushing water during a flush.
  • the pressure piston can be unlocked mechanically, pneumatically or electrically.
  • the pressure cylinder unit absorbs essentially all of the rinsing water.
  • a pressure cylinder unit can be integrated into a box body to save space. It is preferably provided that the pressure cylinder unit is formed at least in regions by an outer wall of the cistern body. This enables a particularly space-saving and inexpensive production.
  • the outlet valve is a servo valve.
  • a valve can have a membrane that closes the valve under water pressure. This enables flushing essentially without closing noise.
  • flushing can be triggered by actuating this element.
  • triggering is comparatively simple and can take place mechanically, pneumatically or electrically.
  • the flushing device has two pressure cylinders which are arranged in the cistern, so-called dual flushing is possible. With a small flush, only one of the two pressure cylinder units is emptied. For a full flush, both pressure cylinder units are emptied at the same time. In both cases, the amount of rinse water is precisely defined.
  • the flushing water quantity of the two pressure cylinder units can be the same or different.
  • 1 is a three-dimensional view of a partially cut-away washing device
  • FIG. 5 shows a section according to FIG. 4, but after rinsing with a subset
  • 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.
  • a revision opening 10 is arranged at the front, but can also be arranged in the ceiling wall 2a.
  • the outlet nozzle 21 leads horizontally into 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 vertical in a pressure chamber 14 and 15, respectively displaceable and sealed with sealing rings 13 against a cylinder wall 41 or 42.
  • 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 a bellows 44 made of a flexible membrane as the closure body.
  • the bellows 44 works together with a valve seat 43 which is arranged on the outlet connection 21. As shown for example in FIG.
  • the bellows 44 is connected to a ventilation duct 33 which can be vented by means of a ventilation member 31.
  • a closure element 34 is raised against the retroactive force of a spring 35 by a valve seat 36 of the ventilation duct 33. 5 can be done with a cable 45.
  • another actuation mechanism is also conceivable.
  • the closure body 34 can be raised pneumatically or with an electric drive. Remote triggering is also conceivable.
  • the bellows 44 forms an interior 40 which is continuously connected to the space 20 via a passage 28.
  • the space 40 is connected via a water pipe 7 according to FIG. 7 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 in each case cooperates with a holder 24 for locking the pistons 11 and 12, respectively.
  • the brackets 24 each have a bearing 25 on which locking means 26 are attached.
  • This Ver ⁇ lock-out means 26, the pistons 11 and 12 may as shown in FIG. 4 shown upper starting position can be releasably locked.
  • the locking means 26 are designed such that the pistons 11 and 12 are automatically locked when the starting position is reached.
  • the locking is released by means of an unlocking device 30 which engages with the locking members 26. 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 on the bearings 25 and bears against a lower end of the piston 11 and 12, respectively. If the piston 11 or 12 is raised in the lower position shown on the left in FIG. 5, the corresponding spring 22 is tensioned. If the upper position is reached, the piston 11 or 12 is locked automatically.
  • Fig. 4 shows the cistern 1 in the starting position.
  • the two pressure chambers 14 and 15 are filled with rinsing water.
  • the springs 22 are tensioned and the pistons 11 and 12 are locked in an upper starting position.
  • the outlet valve 27 and the vent valve 31 are closed.
  • the inlet valve 6 is also closed.
  • the unlocking device 30 is activated by pressing the button 32a shown in FIG. 5 in such a way that the bolt 26a of the pressure cylinder unit 8 is displaced 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 becomes the Closure body 34 of the vent valve 31 is raised.
  • the pressure in the chamber 40 drops and, owing to the pressure difference from the chamber 20, the bellows 44 lifts off 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 space 20 If the space 20 is filled with water, it passes through the passage 16 to the piston 11 and moves it upward due to the water pressure against the retroactive force of the spring 22 until it bears against the bearing 25 and is locked. If a predetermined system pressure has been reached, the regulating valve 5 closes the filling valve 6 Piston 11 is thus back in the starting position and both pressure spaces 14 and 15 and space 20 are filled with water. As soon as the refilling process is initiated, the bellows 44 moves into the closing position due to the increasing pressure in the space 40 and is therefore in contact with the valve seat 43. If air present in space 20 is initially displaced, the vent valve 29 closes due to the buoyancy of a float ball 29a in the water.
  • the system pressure dm refilled cistern is, for example, and preferably about 0.2 bar.
  • the flushing device has the advantage that it can be optimized and adapted to special toilet bowls.
  • the springs 22 can, for example, be replaced by stronger or weaker springs.
  • annular weights 47 for example, can be placed on the pistons 11 and 12 according to FIG. 5. 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 faster and more quickly when flushing at a higher pressure.
  • the regulating valve 5 is adapted to this changed system pressure.
