Definitions

  • the invention describes a toilet cistern, with a wall forming a water tank and an inlet guided through the wall, with which the water tank can be filled, a shut-off valve being arranged in the inlet which cooperates with a shut-off device when a shut-off level is reached in the water tank .
  • Such toilet cisterns are generally known in the prior art and in various designs. There are, for example, cisterns for mounting on a wall, in a pre-wall, or those that stand up on a toilet. There are also pre-wall elements that contain a toilet cistern.
  • the object of the invention is to create a simpler and more cost-effective solution here.
  • the cistern according to the invention is accordingly characterized in that an injector is arranged in the water tank in an installation space above the shut-off level and that an outflow-side exit of the injector from the Water tank is led out.
  • This outlet can serve as an additional water connection.
  • the injector inside the toilet cistern ensures the water supply to the outlet.
  • a backflow from the outlet into the fresh water inlet is prevented. Returning water or water flowing in at the exit simply flows into the cistern. In this way, it can also be prevented that in the event of a negative pressure in a connection line carrying drinking water at the inlet, for example when venting, industrial water is sucked back into the connection line.
  • Another advantage of the injector is that it provides almost the same water pressure as the inlet at the outlet. This means that applications that require water pressure are also possible at the exit.
  • the toilet cistern according to the invention provides an additional water connection without the need for a complex and expensive sanitary installation.
  • An additional advantage is that by replacing or retrofitting an existing toilet cistern, such an additional water connection can be installed without subsequent sanitary installation.
  • the injector can be characterized by a horizontal installation position, in particular its free jet section. This enables a low overall height. In addition, the required standard distance between service water and flushing water in the basin is reduced, which enables a more compact overall height.
  • an overflow pipe is arranged in an outlet of the water container, which protrudes into an interior space of the water container in order to define a maximum fill level, and the injector is arranged above the maximum fill level.
  • the overflow pipe prevents the toilet cistern from being filled above the defined maximum fill level. This prevents the injector arranged above the maximum fill level from filling up with water or being submerged in the water, for example if the previously described shutdown device should be defective. It is thus possible to prevent domestic water from being sucked back from the water tank when there is a negative pressure in a connection line carrying drinking water at the inlet.
  • the injector has a free jet section. This free jet section ensures the separation and thus the return flow of the outlet from the inlet.
  • the free jet section is preferably aligned horizontally and is open down into the water tank. This ensures that any backflowing water can get into the toilet cistern unhindered and not in any way into the inlet.
  • An advantageous embodiment is characterized in that the injector has a collecting opening at an outflow-side end of a free jet section, which is formed on a projection protruding counter to a jet direction given by the free jet section.
  • the protrusion can act like a funnel and ensure that as much water as possible reaches the outlet.
  • the projection can prevent water from area in the vicinity of the collecting opening from creeping or flowing into the collecting opening.
  • the injector can be switched off on the inflow side with a valve.
  • the output can already be deactivated on an inflow side. In this way, it can be prevented in a simple manner that water can be removed at the outlet. This can be necessary or advantageous, for example, in the event of a defect in the output line.
  • the valve can be designed, for example, as a ball valve or as a screw valve.
  • a mechanical actuating device for example, can be present to actuate the valve.
  • This actuating device can for example have a lever or a rotary wheel.
  • valve can be actuated electrically.
  • the actuating device can be a switch or button. This makes it possible to actuate a valve which is arranged in a difficult-to-access location, in particular over large distances and / or where space is limited.
  • a contactlessly controllable actuating device of the valve can include, for example, a solenoid valve or a valve driven by an electric motor.
  • a mains connection and / or batteries can be provided for the power supply.
  • the actuating device is fed from an electrical energy store. This can include a battery, for example.
  • One embodiment of the invention has a generator which is arranged in the inlet and for charging the Energy storage is set up.
  • a self-sufficient toilet cistern can thus be provided, in particular without an energy supply connection.
  • This generator can, for example, have a water wheel that is driven by the water flow in the inlet. In this way, electrical energy for switching the valve can be obtained in a simple manner.
  • the injector can be connected to the inlet with which the water tank can be filled, so that only one external water connection is necessary for the toilet cistern.
  • a feed line for the injector can be routed separately from the feed line into the water tank.
  • the outlet of the injector opens into a backflow-protected water connection.
  • the water connection can have a thread for connecting accessories.
  • a cleaning unit in particular a shower that can be switched off, preferably a Shattaf shower, is connected or can be connected to the injector, in particular to the backflow-protected water connection.
  • a backflow prevention is desirable or prescribed because it cannot be ruled out that the connection device is immersed in a water container while a negative pressure is created in the water pipe.
  • the invention also includes the use of an injector in a toilet cistern to provide a backflow-proof water connection to the toilet cistern.
  • the use of an injector has the advantage that - because of the horizontal installation position of the injector - a low overall height can be maintained.
  • a cleaning unit in particular a shower that can be switched off, preferably a Shattaf shower, is connected to the backflow-protected water connection.
  • the Fig. 1 shows a toilet cistern 1 according to the invention with a wall 2 which, in the example, forms an essentially cuboid water container 3.
  • water tanks are implemented with other basic geometric shapes.
  • an inlet 5 is guided on a narrow side 4, with which the water container 3 can be filled with water 6.
  • a shut-off valve 7, which interacts with a shut-off device 8, is arranged in the inlet 5.
  • This switch-off device 8 can, for example, have a float 9 which floats on the water 6 in the water container 3 or floats in the water 6.
  • the float 9 triggers the shut-off valve 7, so that no more water 6 flows in through the inlet 5.
  • the inlet 5 is connected to a water connection 10, for example via a line 11.
  • the water connection 10 has a shut-off valve 12 with which the water supply to the inlet 5 can be interrupted from the outside.
  • an injector 15 is arranged horizontally in an installation space 13 above the shutdown level 14.
  • the outlet 16 of the injector 15 on the outflow side is led out of the water container 3 through a water outlet 17.
  • the water outlet 17 lies above the shutdown level 14 and has an external thread 18 in the example.
  • a hose line 19 is connected to the water outlet 17, to the free end 20 of which a Shattaf shower 21 is connected.
  • other devices can also be connected to the hose line 19 or the water outlet 17.
  • the water outlet 17 is arranged on the side 22 of the wall 2 opposite the inlet 5.
  • the water outlet 17 can also be arranged at another point on the wall 2.
  • the inlet 23 of the injector 15 is connected via an internal line 24 to a valve 25 arranged outside the toilet cistern 1.
  • the valve 25 is connected to the water connection 10 and has an actuating device 26 with which the valve 25 can be opened or closed. In this way, the flow to the injector 15 can be prevented.
  • the valve 25 is designed as a ball valve and the actuating device 26 as a lever.
  • the injector 15 has a free jet section 27 which essentially prevents the return flow from the outlet 16 to the inlet 23.
  • the free jet section 27 is aligned horizontally and is open down into the water tank 3. Water flowing back through the outlet 16 thus flows through this opening 43 into the water container 3 and cannot get into the inlet 23 of the injector.
  • the injector 15 thus provides a backflow protection for the water outlet 17.
  • the free jet section 27 in the example also has a collecting opening 28 which is formed on a projection 29 protruding against a beam direction given by the free jet section 27.
  • an overflow pipe 31 is arranged, which protrudes into an interior of the water container 3 in order to define a maximum fill level 32.
  • the injector 15 is preferably also arranged above the maximum fill level 32 in order to prevent the injector 15 from being filled with water 6 and thus no longer separating the inlet 23 and outlet 16.
  • the toilet cistern 1 has a drain 33 for the flushing water and an actuator 34 ( Fig. 6 ) to trigger the flushing process, which are known per se and are therefore not explained in more detail here.
  • FIG. 3 shows a toilet cistern 1 which is essentially the same as the toilet cistern 1 of FIG Fig. 1 is equivalent to.
  • the remarks on Fig. 1 can thus be traced back to the exemplary embodiment Fig. 2 read.
  • the reference numerals were analogous to Fig. 1 forgive.
  • the outlet 16 of the injector 15 is led out of the water tank 3 via a closed line 35.
  • Fig. 2 shows that the outlet 16 is led out through the lower wall of the water container 3.
  • the line 35 can be guided to any other position.
  • the water outlet 17 can be placed in a position adapted to the installation location.
  • FIG. 3 shows an alternative embodiment of a toilet cistern 1 according to the invention. Again, the same reference numerals are used so that the explanations relating to FIGS Fig. 1 and 2 on Fig. 3 let read.
  • this embodiment has an electrically operated valve 36 in FIG Line 24 to the injector 15, which is arranged within the installation space 13 above the maximum fill level 32.
  • a generator 38 for generating electrical energy is arranged in the supply line 37.
  • This generator 38 converts flow energy of the water into electrical energy.
  • the generator 38 can have a water wheel that is driven by the water flow. The water wheel can be connected to a dynamo.
  • the inlet 5 for filling the water container 3 is arranged after this generator 38. In this way, electrical energy is generated with each flushing process, that is, with each filling process.
  • the toilet cistern 1 can have an energy store, for example a rechargeable battery, in which excess electrical energy is stored. In further exemplary embodiments, the energy store can be charged in a different way, for example by energy harvesting.
  • a switch or button can be arranged on the toilet cistern 1.
  • the electric valve 36 has a contactlessly controllable actuating device 39.
  • a remote control 40 which has a release button 41, is provided for this purpose.
  • This remote control 40 can be connected to the actuating device 39 by radio or infrared light.
  • the valve 36 can be switched on and off via the trigger button 41. However, it can also have a time control so that the valve 36 is automatically closed after an adjustable time after opening.
  • the one in the Fig. 4 The embodiment shown is a combination of the embodiments of Fig. 1 and 3 . It has an electric valve 36 according to FIG Fig. 3 and a water outlet 17 according to FIG Fig. 1 on.
  • Fig. 5 is a variant of the execution of the Fig. 3 , whereby the inlet 5 takes place here via an internal water connection 10.
  • the toilet cisterns of the Figs. 1 to 5 are each designed as independent units that can be mounted hanging on a wall or standing on a toilet.
  • the Fig. 6 finally shows a conventional front wall element 42 in which a toilet cistern 1 according to FIG Fig. 5 is arranged.
  • the pre-wall element 42 is used for installation in a pre-wall installation.
  • Such pre-wall elements are known per se, so that the further features of this pre-wall element 42 will not be discussed in more detail.
  • the invention thus proposes a toilet cistern 1 with a wall 2 which forms an essentially cuboid water container 3.
  • An inlet 5, with which the water tank 3 can be filled, is guided through the wall 2.
  • a shut-off valve 7 is arranged in the inlet 5, which works together with a shut-off device 8, which triggers the shut-off valve 7 when a shut-off fill level 14 is reached in the water tank 3.
  • an injector 15 is arranged in an installation space 13 above the shutdown level 14. The outlet 16 of the injector 15 on the outflow side is led out of the water tank 3.
