Definitions

  • the invention relates to a drain fitting for a toilet cistern according to the preamble of patent claim 1.
  • a drain fitting is in the document WO2006 / 012650A1 described.
  • a toilet cistern has a filling valve connected to the water supply network and a drain valve.
  • the toilet cistern can be filled with water to a specified level.
  • the drain valve is usually made up of a drain nozzle mounted on the bottom of the cistern and an overflow pipe that can be adjusted in stroke. In its closed position, the overflow pipe closes a flow passage through the drain connection.
  • the overflow pipe By pressing a pushbutton on the user side, the overflow pipe can be lifted into its open position, in which a quantity of flush water can flow out of the drain connection of the toilet cistern.
  • the push button is in operative connection with the overflow pipe via a mechanical linkage.
  • a generic drain fitting is also known in which the pushbutton is not connected to the overflow pipe via a mechanical linkage, but via a pneumatic system.
  • the pneumatic system has a first bellows positioned on the push button, which is connected via a pneumatic line to a second bellows positioned on the overflow pipe.
  • the push button is pressed, the first bellows is compressed and an overpressure is thus generated, which can be applied to the second bellows.
  • the overpressure is applied, the second bellows expands, whereby the overflow pipe is moved into its open position.
  • the above pneumatic system is both space-consuming and component-intensive. The implementation of the pneumatic system is therefore associated with high costs and is complex to carry out in terms of assembly.
  • the object of the invention is to provide a drain fitting for a toilet cistern which, compared to the prior art, can be implemented in a reduced space and in components.
  • a bellows is dispensed with in the pneumatic system, which adjusts the stroke of the overflow pipe when overpressure is applied.
  • the pneumatic system according to the invention has precisely one pneumatic actuator which can be subjected to a negative pressure to adjust the stroke of the overflow pipe.
  • the drain fitting also has a vacuum unit that is fluidically connected to the pneumatic actuator. When activated by the user, the negative pressure unit generates negative pressure acting on the pneumatic actuator in order to adjust the stroke of the overflow pipe.
  • the pneumatic system can be implemented as a bellows, a piston-cylinder unit or as a diaphragm lift system.
  • the membrane lifting system can, for example, have at least one working chamber which can be acted upon by negative pressure and which is delimited by a deformable membrane.
  • the deformable membrane can be connected to the overflow pipe.
  • the pneumatic actuator can be a bellows which contracts like an accordion when a negative pressure is applied and, when the negative pressure is released, pulls apart (that is, expands) like an accordion.
  • the negative pressure unit can be an electrically controllable vacuum pump or a water-carrying negative pressure unit, that is to say a vacuum nozzle or a water jet pump.
  • the vacuum nozzle / water jet pump can be connected to the pneumatic actuator via a vacuum line. If water flows through the vacuum nozzle / water jet pump, air is therefore sucked out of the pneumatic actuator, that is, a negative pressure is generated in the pneumatic actuator.
  • the above water-carrying negative pressure unit can have a throttle point with a flow cross-section constriction between its water inlet side and its water outlet side in the manner of a Venturi nozzle.
  • the vacuum line can preferably open into the flow channel of the vacuum unit at the throttle point.
  • the pneumatic actuator (that is, for example, the bellows) can be arranged in the vertical direction of the drain fitting, in particular in alignment above the overflow pipe.
  • the pneumatic actuator can preferably be connected to the overflow pipe via a rigid connecting element which, for example, coaxially extends the overflow pipe upwards.
  • the vacuum unit can be arranged in particular in alignment above the pneumatic actuator, whereby a particularly space-saving design of the pneumatic system is achieved.
  • the water-carrying negative pressure unit can be connected on its water inlet side to a control line which can be connected to the water supply network.
  • the control line can preferably branch off from a supply line leading to a filling valve of the toilet cistern.
  • the line pressure which is already present, is used to generate the negative pressure in the negative pressure unit without the need for additional external energy (for example, pressure actuation by the user or electrical energy).
  • the water-bearing The water outlet side of the vacuum unit can open directly into the interior of the toilet cistern.
  • the above variant is particularly advantageous for a toilet repair measure in which the water supply line to the toilet cistern is shut off at a corner valve in preparation.
  • the water supply to the toilet cistern and to the vacuum unit is interrupted.
  • the fitter In the case of a conventional toilet cistern, in which the push button is connected to the drain valve via a mechanical linkage, the fitter must empty the toilet cistern before starting the repair in order to prevent water from leaking out of the toilet cistern if the push button is unintentionally operated .
  • such a preventive emptying of the toilet cistern can be omitted for the following reason: Because of the angle valve shut-off, no water can be passed through the control line, so that the negative pressure unit cannot generate negative pressure. The drain valve thus remains reliably closed even if the push button is unintentionally actuated.
  • the vacuum unit can be activated by the user.
  • a control valve that can be operated by the user can be arranged for this purpose in the control line leading to the negative pressure unit, that is to say upstream of the water-carrying negative pressure unit.
  • the control valve can be a time-controlled actuation valve, for example a so-called self-closing valve.
  • the control valve can have a control piston which can be stroke-adjustable in a valve housing.
  • the control piston can be on the user side by means of at least one operated pushbutton can be adjusted.
  • the control piston In its non-actuated position, the control piston is spring-preloaded into a closed position in which a control piston valve plate is in sealing contact with a valve seat fixed to the housing and a flow path through the control valve is closed as a result.
  • the push button is pressed over a stroke of the key
  • the control piston is moved into its open position against the spring preload force.
  • the flow path through the control valve is released, so that water flows through the water-bearing negative pressure unit.
  • the control piston is returned to its closed position via a return stroke under the action of the spring preloading force.
  • the length of the above key stroke of the push button correlates with a reset time interval within which the control piston is returned to its closed position after the push button has been released.
  • the water-carrying negative pressure unit is traversed by the water volume flow and a negative pressure is generated which acts on the pneumatic actuator.
  • the length of the key stroke has a direct influence on the amount of flush water flowing out of the toilet cistern.
  • the user-operated push button can be assigned a stroke adjusting member that sets the maximum key stroke of the push button and thus also the reset time interval.
  • the drain fitting can have a first push button, when actuated a large amount of flush water flows out of the toilet cistern, and a second push button, when actuated a small amount of flush water flows out of the toilet cistern.
  • the user can determine the amount of flush water.
  • the two pushbuttons can be connected to the control piston in a force-transmitting manner, in particular for example with the interposition of a cross member, in such a way that the second pushbutton remains in its rest position when the first pushbutton is pressed.
  • the key stroke covered by one of the pushbuttons is thus identical to the piston stroke covered by the control piston.
  • each of the two pushbuttons is assigned a stroke adjustment member, with the aid of which the maximum possible stroke travel of the first and second pushbuttons can be set independently of one another. With such a control valve, different amounts of flushing water can be set variably.
  • FIG. 1 a waste set installed in a toilet cistern 1 with an associated pneumatic system 21 is shown.
  • the drain fitting has a drain connector 5 on the cistern floor, which is in flow connection with a toilet bowl in a manner not shown.
  • the drain connection 5 rests with a radially widened circumferential annular shoulder 7 on the opening edge region of an outlet opening on the bottom of the cistern floor.
  • the annular shoulder 7 of the drainage connection 5 is extended upwards with a circumferential housing wall 9 formed thereon, in which flow openings 11 are formed which are evenly distributed in the circumferential direction.
  • a stroke-adjustable overflow pipe 13 is arranged radially inside and coaxially to the housing wall 9 and rests with its radially outer valve disk 15 on a valve seat 17 formed on the annular shoulder 7 in a liquid-tight manner.
  • the circulating pipe 13 forms together with the drain connection 5 a drain valve 19, which can be actuated via the pneumatic system 21 of push buttons 23, 25, which in the Fig. 1 are delimited by a decorative plate 26 and installed in a building wall 28.
  • the pushbuttons 23, 25 When the pushbuttons 23, 25 are pressed, the circulation pipe 13 is moved by means of the pneumatic system 21 from one in the Figure 1 shown closed position into an open position ( Figures 6 and 7 ) stroke adjusted.
  • a filling valve is also installed in the toilet cistern 1 with which the toilet cistern 1 is filled with water up to a predetermined level.
  • the filling valve On the inlet side, the filling valve is connected to a supply line 29 leading to the water supply network.
  • the pneumatic system 21 has a bellows as the pneumatic actuator 31 and a vacuum nozzle 33 as the negative pressure unit.
  • the vacuum nozzle 33 is constructed in the manner of a Venturi nozzle and is connected on the inlet side to a control line 35 which branches off from the supply line 29.
  • a control valve 43 is arranged in the control line 35 and can be actuated via the pushbuttons 23, 25 which can be operated by the user.
  • a water flow path from the supply network to the vacuum nozzle 33 is opened in the control valve 43 and this is connected to a water volume flow ⁇ ( Fig. 3 or 6th ) flows through. In this way, a negative pressure is generated in the negative pressure line 37, with which the bellows 31 is drawn together.
  • the vacuum nozzle 33 opens into the interior of the toilet cistern 1.
  • the vacuum nozzle 33 has a throttle point with a flow cross-sectional constriction between its water inlet and water outlet side, at which a vacuum line 37 opens into the nozzle channel of the vacuum nozzle 33.
  • the vacuum nozzle 33 and the bellows 31 are to form a unit B ( Fig. 2 ) directly connected to each other.
  • the vacuum nozzle 33 in the Figure 2 a connection piece 39 through which the vacuum line 37 leads.
  • a pipe extension 41 of the bellows 31 is pushed onto the connecting piece 39 of the vacuum nozzle 33 and optionally fixed to it by means of a fastening clip, not shown.
  • the bellows 31 is in the Fig. 2 with its bellows base 45 facing away from the pipe extension 41 is coupled to a connecting rod 47 which in turn is fastened to the upper end of the overflow pipe 13.
  • control valve 43 shown together with a button housing 49 in which the two pushbuttons 23, 25 are arranged, also forms a structural unit.
  • the control valve 43 has a control piston 53 which can be lifted in a valve housing 51 on.
  • the control piston 53 is connected to the two pushbuttons 23, 25 in a force-transmitting manner with the interposition of a cross member 55.
  • the control piston 53 In the, in the Figure 3 In the non-use position shown, the control piston 53 is spring-preloaded into a closed position by means of a spiral spring 57.
  • the closed position shown is the control piston 53 with its valve plate 59 in sealing contact with a valve seat 61 fixed to the housing, whereby the flow path through the control valve 43 is closed.
  • the first and second pushbuttons 23, 25 can be adjusted into an open position over the maximum possible key travel h 1 , h 2 against the spring preload force generated by the spiral spring 57 ( Figure 4 or 5 ). In the open position, the flow path through the control valve 43 is released. When the pressure of the respective pressed pushbutton 23, 25 is released, the pushbutton 23, 25 is returned to its closed position under the action of the spring biasing force of the spiral spring 57.
  • the control valve 43 has two stroke adjusting members 63, 65 which are arranged in the key housing 49 so as to be adjustable in one stroke direction.
  • Each of the stroke adjustment members 63, 65 is assigned to one of the pushbuttons 23, 25.
  • the stroke adjustment members 63, 65 act as depth stops which limit the stroke path of the respective pushbutton 23, 25.
  • the control piston 53 When the pushbutton is released after the pushbutton has been actuated, the control piston 53 automatically returns to its closed position under the action of a spring force, specifically within a reset time interval. Within the reset time interval, the flow path through the control valve 43 remains open, so that a water volume flow ⁇ continues to be passed through the vacuum nozzle 33 and a negative pressure is thereby generated.
  • the length of the reset time interval correlates with a key travel length. This means that with a large key stroke length, the return of the push button 23, 25 is longer takes longer than with a shorter key travel length. Correspondingly, with a large key stroke length, a larger amount of flush water can flow out of the toilet cistern 1 than with a smaller key stroke length.
  • each of the pushbuttons 23, 25 can be assigned its own amount of flushing water flowing out of the toilet cistern 1. For example, when the first push button 23 is actuated, a small amount of flush water can flow out of the toilet cistern 1. In contrast, when the second pushbutton 25 is actuated, a larger amount of flush water can flow out of the toilet cistern 1.
  • the bellows 31 is positioned in the vertical direction of the drain fitting in alignment above the overflow pipe 31 according to the figures.
  • the vacuum nozzle 33 is also positioned approximately in alignment above the bellows 31.
  • FIG. 8 a further development of the pneumatic system 21 shown in the previous figures is shown.
  • the bellows guide 67 has a hollow cylindrical, pot-like bellows housing 69 which is designed to be rotationally symmetrical with respect to a housing axis G and which is attached to the vacuum nozzle 33 with its pot bottom 71.
  • guide channels 73 are formed, in which guide pins 75 are guided axially parallel to the housing axis G.
  • the guide pins 75 are fastened to the connecting rod 47 via transverse webs 77.
