Definitions

  • the invention relates to a flushing device according to the preamble of claim 1.
  • Flushing devices of the type mentioned have long been known and are also referred to as Druck Fashionkasten.
  • the water present in the tank for flushing is at rest under the pressure of an existing pressure chamber above the water.
  • the pressure chamber contains air that can not leave the container and has an overpressure.
  • the overpressure is generated when refilling the cistern.
  • a rinsing trigger the closure body of the drain fitting is raised and the rinse water present in the container is discharged while relaxing the air of the pressure chamber in a toilet bowl.
  • the rinse water thus leaves the container not only due to its own weight, but also under the effect of the pressure chamber.
  • the pressure in the container causes the rinse water to be released at an increased rate in a rinse.
  • An example of such a flushing device is from the US 6,343,387 B1 known.
  • the advantage of such flushing devices is in particular that it can be flushed with comparatively little water or high energy.
  • a flushing device in which a spiral spring is provided with which flushing water is kept under pressure in a chamber. at a rinse, the rinse water is ejected under relaxation of the rinsing spring.
  • the US 1,645,264 discloses a flushing device with a pressurized chamber.
  • an outlet valve with a valve body is arranged, which is connected via a rod with a lever.
  • the valve body By pivoting the lever, the valve body can be raised and thus a flushing triggered.
  • a spring is tensioned.
  • the lever When the lever is released, the valve body is moved down onto the valve seat and the lever is pivoted to the starting position.
  • Each purge quantity is dependent on the time during which the valve is kept open. This practically never rinses with the optimum amount of water.
  • the water consumption is regularly too high in such flushing devices or it is flushed with too little water, which is disadvantageous for hygienic reasons.
  • the DE 31 30 452 A discloses a flushing device having a cistern and in the inlet to the cistern a flush valve. Optionally, it can be rinsed with the cistern or with the flush valve.
  • the generic GB 497 765 A discloses a cistern in which the closure body of the outlet valve with a two-armed lever can be raised to different heights, so that the outlet valve closes within different time periods and different amounts of flushing water are discharged.
  • the WO 02/077377 A constitutes prior art under Article 54 (3) EPC and discloses a pressurized cistern with at least one pressure vessel. This has a locked spring-loaded Pressure piston, which is releasably locked. For rinsing the pressure piston is unlocked and thus ejected the water present in the pressure vessel.
  • the invention has for its object to provide a flushing device of the type mentioned, which allows a further saving of flushing water.
  • the object is achieved in a generic flushing device according to claim 1.
  • the flushing device has means for flushing with a subset of the flushing water.
  • the flushing process can be interrupted. This makes it possible to carry out either a full or partial flush. It is therefore not necessary in all cases to rinse with the entire amount of flushing water present in the container. It can also be rinsed with a subset of the water present where such a subset is sufficient for rinsing. In practice, this is possible in many cases, so that a great deal of water, and in particular fresh water, can be saved with the flushing device according to the invention, which is a considerable advance from an economic and ecological point of view.
  • the interruption of the flushing can be set arbitrarily or fixed. With a fixed setting, the flushing amount is determined for a subset and is for example 3 l.
  • the triggering can be mechanical or non-contact.
  • the flushing device is also particularly suitable for an automatic toilet system, in which, for example, sensors automatically trigger a full or partial flush.
  • the flushing device have a force-loaded part which moves the valve body downwards onto the valve seat during a flushing interruption. This allows for comparatively simple Means a quick break during different phases of flushing.
  • the force-loaded part is slidably mounted according to a development of the invention in the drain fitting. This allows a particularly compact design and has the particular advantage that the installation of the flushing device is not more complex than before.
  • the part is permanently integrated in the drain fitting and is installed during assembly of this valve without any further assembly steps.
  • the force-loaded part is spring-loaded.
  • This part is held, for example, with a locking device in the tensioned state. After releasing the locking device of the part acts under the force of the spring on the closure body and forces it into the closed position.
  • the force-loaded part is mounted in said piston.
  • a compression spring is tensioned.
  • the compression spring can in this case be replaced by another force means, for example a weight or a magnet.
  • the rinsing device 1 shown in Figure 1 comprises a container 2, which is a pressure vessel and consists for example of two interconnected bowl-shaped halves 2a and 2b.
  • the container 2 is designed, for example, for an internal pressure of 2 bar.
  • a bottom 40 of the container 2 is an outlet opening 38 which leads into a nozzle 3, which is connected via a rinsing sheet not shown here with a toilet bowl, also not shown here.
  • a drain fitting 6 is arranged, which has a closure body 7, which is displaceable in a guide tube 9 is mounted and having a sealing ring 41 in a lower end, which rests with a closed drain fitting 6 on a valve seat 5.
  • the container 2 is filled according to Figure 1 in the rest position with rinse water 14.
  • a pressure chamber 15 containing air.
  • the air has an overpressure which acts on the surface 42 of the rinse water 14.
  • the pressure is for example 3 bar.
  • a vent line 18 which is open at an upper end 18a to the environment and in which a vent valve 19, for example, a ball valve, is arranged.
  • the vent line 19 also serves to refill the container 2 and has below the vent valve 19 according to Figure 3, a passage 43 in an interior 44 of a connecting device 39.
  • the pressure chamber 15 includes only a partial volume of the container 2, which is arranged in the upper region of the container 2 ,
  • the vent line 18 dives with a lower open end 18 b in the rinse water 14th
  • the connection device 39 serves for the connection of a pressurized water line 24 in which there is, for example, a continuous water pressure of about 3 bar.
  • the connecting device 39 has a pressure regulating valve 45, which connects the pressurized water line 24 with the interior 44 and in a valve chamber 20 has a valve ball 21 which cooperates with a valve piston 22 which is tensioned by a tension spring 23 against the valve ball 21. In the figure 1, the pressure regulating valve 45 is closed.
  • the closure body 7 has at its upper end a piston 16 with an interior 17 which is open at the top. This interior 17 is above a flow gap 46 with the interior 44 connected. The interior 17 is thus filled with water, which has the same pressure in Figure 1 as the water in the interior 44 and the rinse water 14 in the container 2.
  • the piston 16 is sealed with a circumferential lip seal 10 against the inside of the bottom open guide tube 9.
  • the interior 17 is provided at its lower end with a safety pressure relief valve 8, which has a pressure spring 8a. If a maximum permissible pressure is exceeded in the interior 17, then the safety overpressure valve 8 opens and discharges water via the outlet opening 38 to the outside.
  • the closure body 7 is pressed against the valve seat 5 with a force due to a pressure difference between pressurizing surfaces. At two bar internal pressure in the container 2, this force is for example seven kp.
  • the interior 17 is connected via a vent valve 11 with a vent line 13, which leads according to Figure 1 at a lower end 13a via the nozzle.
  • the vent valve 11 has a valve slide 11 a, which is connected to close or open the valve 11 via a control device 55 with keys A and B of an actuator 56.
  • the vent valve 11 is closed.
  • the vent valve 11 can be opened.
  • the interior 17 is then connected to the ambient air. With key A, a full flush is triggered and with key B a partial flush.
  • the drain fitting 6 has a further guide tube 34, which is likewise open at the bottom and in which a piston-shaped part 50 is displaceably mounted and sealed with a lip seal 30 against the guide tube 34.
  • FIG. 1 shows the piston-shaped part 50 in an upper position, in which a arranged in this part 50 coil spring 49 is stretched.
  • the part 50 has a downwardly projecting portion 35 and at an upper end a locking element 31.
  • the piston-shaped part 50 is preferably formed in one piece and, for example, an injection molded part made of plastic.
  • the locking element 31 forms with a slider 32 a locking device 48.
  • a spring 33 holds the locking slide 32 in the locking position shown in Figure 1. By moving the slider 32 in the direction of the arrow 51, the piston-shaped part 50 can be unlocked, so that it is moved under the pressure of the spring 49 down.
  • the flushing device according to FIG. 1 is in the rest position and is ready for flushing.
  • the air in the pressure chamber 15 is stretched at a pressure of for example 2 bar.
  • the pressure regulating valve 39 and also the venting valve 19 and the venting valve 11 are closed.
  • the drain fitting 6 To trigger a full flush, the vent valve 11 is opened by pressing the A key.
  • the interior 17 is thereby connected via the vent line 13 with the ambient air.
  • the pressure in the interior 17 drops and the closure body 7 moves according to Figure 2 in the direction of the arrow 25 upwards.
  • the drain fitting 6 is thereby opened and the rinse water 14 is discharged under the weight and under the pressure of the pressure chamber 15 through the opening 38, as indicated in Figure 2.
  • vent valve 19 opens so that all water 14 can be dispensed from reservoir 2.
  • the closure body 7 moves downwards until the drain fitting 6 is closed.
  • the pressure regulating valve 45 is still open, so that even with the drain set 6 water flows into the container 2 and fills it. Since the vent valve 11 is now closed, the air in the pressure chamber 15 can not escape and is compressed by the rising water. If the water surface 42 is at the level according to FIG. 1, then the pressure in the rinsing water 14 is so great that the venting valve 19 closes. The supply of water into the container 2 is thus terminated. Due to the increase in pressure in the interior 14 now also closes the pressure regulating valve 45. The flushing device 1 has thus again reached the rest position according to Figure 1 and is ready for another flushing.
  • the rinsing explained with reference to FIG. 1 is a full rinse, that is, substantially all of it is present in the container 2 Water 14 used for rinsing. Excluded here is the water in the interior 44 and in the interior 17 of the piston 16. If only a portion of the present rinse water 14 is required for a rinse, the button B is actuated, thus triggering a partial rinse. As explained above, the slide 11a is moved via the control device 55, thus triggering a flush. According to FIG. 1, the closure body 7 is prematurely brought into the closed position with the aid of a level sensor 57 via the control device 55. For this purpose, the locking slide 32 according to FIG.
  • FIG. 3 is displaced in the direction of the arrow 51 by the control device 55 on the basis of a signal of the level sensor 57.
  • the button B can also be connected via a mechanical control device with the locking slide or trigger the unlocking via a pressure control.
  • the piston-shaped part 50 is unlocked. This part 50 rests with the downwardly projecting portion 35 with the drain fitting 6 open at an upper wall 52 of the valve body 7, as FIG. 2 shows.
  • the closure body 7 After unlocking the piston-shaped part 50 is moved under the action of the tensioned spring 49 down. Due to the force of the spring 49, the closure body 7 simultaneously moves downwards. The force of the spring 49 is now designed so that the frictional force of the lip seal 30 on the guide tube 34 can be overcome.
  • the closure body 7 is moved by the piston-shaped part 50 according to Figure 3 in the direction of the arrow 58 down until the drain fitting is closed.
  • FIG. 1 shows the closure body 7 in the lower position, in which the drain fitting 6 is closed. The flushing process is over.
  • FIG. 4 shows a toilet installation 100 with a flushing device 101 and a toilet bowl 109.
