Definitions

  • the present invention relates to a filling valve for filling a cistern according to claim 1, an arrangement according to claim 14 and an assembly method according to claim 16.
  • the WO 2017/219306 discloses a filling valve which is adjustable in height so that it can be used for different cisterns.
  • the height adjustment is according to the WO 2017/219306 released via a telescopic mechanism in the water inlet pipe.
  • the latter is constructed in two parts with two tube parts and the two tube parts can be telescopically displaced relative to one another.
  • the problem here is that the annular gap between the two pipe parts has to be sealed with a sealing element, so that there is no uncontrolled escape of flushing water from the annular gap.
  • This sealing element is also disadvantageous in that the height adjustment is made difficult due to the friction of the seal.
  • the object according to claim 1 solves this problem Filling valve for filling a flushing cistern, a water duct with an inlet and an outlet, an inflow valve arranged in the water duct, a control element for actuating the inflow valve, a housing on which the inflow valve and the outlet are arranged, and a support element which supports the housing in its installed position stored in the cistern.
  • the support element and the housing are connected to one another via a longitudinal guide in such a way that the position of the housing can be adjusted relative to the support element. This means that the housing can be displaced relative to the support element and that the position of the housing relative to the support element can be adjusted via this displaceability.
  • the water duct is partially formed with a hose.
  • the water supply channel consists of a hose in sections.
  • the hose is attached to the support element via a first attachment point and to the housing via a second attachment point.
  • the hose lies between the first attachment point and the second attachment point in such a way that a change in length of the water duct caused by the relative displacement between the housing and the support element can be compensated for by a change in the position of the hose.
  • a hose is understood to mean a tubular element that is flexible with respect to its central axis or its hose axis.
  • the hose axis and thus also the hose can have one or more curved sections.
  • the hose is deformed with respect to its central axis.
  • the housing and the support element are closer together than in a second position. If the housing and the support element are in the first position, the hose runs with curved sections, in particular with curved sections with small radii. The excess length of hose results in said curved portions. If the housing and the support element are in the second position, the hose runs in a straight line or with a curved section with large radii.
  • the entrance of the water duct is arranged on the support element.
  • the water duct Seen from the entrance, the water duct extends through the support element, through the hose and then through the housing to the exit.
  • the inflow valve can be moved from a closed position to an open position, flushing water then flowing from the inlet through the water-guiding channel to the outlet. In the closed position, the inflow valve is closed.
  • the hose preferably has a compensation loop.
  • a compensation loop With a compensation loop, the deformation of the hose for length compensation when adjusting the height can be achieved very easily.
  • the compensation loop extends at least partially around a reference axis lying transversely to the hose axis. In a second variant, the compensation loop extends at least once completely around a reference axis lying transversely to the hose axis.
  • the hose is preferably firmly connected with its ends to the respective attachment points.
  • each of the attachment points has an opening, with the ends of the tube protruding into the respective attachment point. Said opening is then followed by the water duct in the support element or in the housing.
  • the hose is preferably connected to the respective fastening point by means of a material-locking and/or form-locking connection.
  • the hose is preferably arranged in front of the inflow valve, viewed in the flow direction of the water.
  • the inflow valve is preferably located in the housing.
  • the arrangement of the hose in front of the inflow valve has fluidic advantages on the one hand and on the other hand it allows the inflow valve to be above the water line, which results from the water level when the tank is full, when installed in the cistern.
  • the support member has a support portion, a mounting portion extending from one side of the support portion, and a sidewall extending from another side of the support portion.
  • Said entrance preferably extends through the attachment portion.
  • the attachment section preferably has an external thread which is guided through an opening in the cistern.
  • the filling valve can be connected via the external thread cistern to be attached.
  • the housing has a side wall, the side wall of the housing and the side wall of the support element comprising said longitudinal guide.
  • the side walls are designed in such a way that one side wall protrudes into the interior space which is formed by the other side wall.
  • the side walls In the area of the longitudinal guide, the side walls essentially have the same cross-sectional shape.
  • the side walls are preferably designed in such a way that the housing cannot be pivoted with respect to the support element and that the housing can be displaced along a rectilinear movement with respect to the support element.
  • the side wall of the housing and/or the side wall of the support member define an interior space, the hose preferably lying entirely within said interior space.
  • the side walls protect the hose and further prevent the hose from lying in an uncontrolled position in the cistern. In an uncontrolled position, it could collide with other elements in the cistern, such as a flush valve.
  • the outlet of the water-guiding channel preferably has at least one outlet opening which is arranged in such a way that the flushing water can leave the water-guiding channel in a free jet.
  • a plurality of outlet openings are particularly preferably arranged, so that the water jet emerges with less noise.
  • the housing preferably has an opening, with the outlet opening being oriented in the direction of said opening such that escaping water can flow into the housing, the housing having at least one outflow opening through which the flushing water can escape from the housing.
  • the opening of the housing is followed by a guide element, which diverts the washing water entering the housing to the inside of the side wall.
  • the side wall of the support element has at least one Outflow opening through which the flushing water can escape through the side wall.
  • the flushing water flows from the housing into the spatial area delimited by the side wall of the support element.
  • the hose is preferably designed as a hose lying freely in the cistern. This means that the hose is not held within the side walls, as mentioned above, but rather the hose lies freely in the cistern.
  • the longitudinal guide is next to the hose. This design has the advantage that the structure of the support element and the housing can be made somewhat simpler.
  • the control element is preferably a float which acts on the inflow valve, the float preferably being arranged in a float chamber in the housing.
  • the arrangement of the float in a float chamber lying on the housing results in the advantage that the float always comes to rest at the correct altitude when the altitude is adjusted.
  • One arrangement comprises a filling valve as described above and a cistern, the housing with the inflow valve and the outlet lying above the waterline at the maximum filling level in the cistern.
  • the water line is defined by the maximum filling level of the flushing water in the cistern.
  • the cistern also has a fastening opening, the filling valve being fastened to the fastening opening via the inlet and the fastening opening being preferably arranged at the bottom of the cistern.
  • a method for installing a filling valve according to the above description in a cistern is characterized in that the height of the filling valve is adjusted in one assembly step by moving the housing relative to the support element, with the change in length of the water-guiding channel caused by the relative displacement between the housing and the support element being a change in the position of the hose is compensated.
  • FIG. 1 to 6 an embodiment of a filling valve 1 for filling a cistern is shown.
  • the filling valve 1 comprises a water duct 2 with an inlet 3 and an outlet 4 . Between the inlet 3 and the outlet 4 an inflow valve 5 is arranged in the water duct 2 .
  • the inflow valve 5 is moved from a closed position to an open position. In the open position, flushing water can flow from the input 3 through the water duct 2 to the output 4 and the cistern is filled accordingly. In the closed position, the water supply channel 2 is blocked.
  • the filling valve 1 also includes a control element 6 for controlling the inflow valve 5.
  • the control element 6 has the form of a float here.
  • the float weight becomes effective and opens the inflow valve 5.
  • the float weight becomes ineffective and the inflow valve 5 is closed again.
  • the float is mounted on the housing 7 in a float chamber 23 .
  • the filling valve 1 further comprises a housing 7 on which the inflow valve 5 and the outlet 4 are arranged, and a housing 7 which is connected to it Support element 8.
  • the support element 8 supports the housing 7 in the cistern.
  • the support element 8 and the housing 7 are connected to one another via a longitudinal guide 9 .
  • the longitudinal guide 9 is designed in such a way that the position of the housing 7 relative to the support element 8 can be adjusted. Accordingly, the position of the housing 7 in the cistern is adjustable. This means that the filling valve 1 can be used in cisterns with different dimensions, with the filling valve 1 being able to be adapted to the respective cistern size.
  • the longitudinal guide preferably allows a displacement path between the housing 7 and the support element 8 in the range from 0 to 20 centimeters. That is, the length L according to the figure 4 can be increased by 0 to 20 centimeters to the length Lv according to the figure 6 to be changed.
  • the water duct 2 is formed with a hose 10 in sections.
  • the hose 10 is attached to the support element 8 via a first attachment point 11 .
  • the hose 10 is attached to the housing 7 via a second attachment point 12 .
  • the hose 10 lies between the first attachment point 11 and the second attachment point 12 in such a way that a change in length of the water duct 2 caused by the relative displacement between the housing 7 and the support element 8 can be compensated for by a change in the position of the hose 10 .
  • the figures 1 , 3 and 4 show the filling valve 1 in a first position.
  • the figures 2 , 5 and 6 show the filling valve 1 in a second position.
  • the housing 7 is closer to the support element 8 than in the second position.
  • the filling valve 1 is used in the first position in a cistern and can then be adjusted in height. This means that when it is inserted, the filling valve 1 has a low height, which is advantageous because of the tight space conditions in a cistern.
  • the tube 10 has a compensation loop 13 .
  • the compensation loop 13 extends around a reference axis R lying transversely to the axis S of the hose.
  • the central axis of the tube 10, that is to say the tube axis S, extends around the reference axis R around.
  • the tube 10 extends around the reference axis R once.
  • the hose 10 can also be arranged in other ways.
  • compensation loops 13 which do not extend completely, ie at least partially, around said reference axis R.
  • These are corresponding curved sections of the hose 10.
  • the hose tends to be stretched in the second layer and tends to be compressed in the first layer.
  • the hose 10 is firmly connected with its ends to the respective fastening points 11, 12.
  • the attachment points 11, 12 are each designed as cylindrical openings.
  • the free ends of the tube 10 extend into these cylindrical openings.
  • the free ends of the hose 10 are preferably attached to the cylindrical openings by means of a material connection and/or a non-positive connection.
  • the water duct 2 extends from the inlet 3 through the support element 8, through the hose 10 and then through the housing 7 to the outlet 4.
  • the water duct 2 is closed by corresponding side walls in the support element 8 or limited in the housing 7.
  • the inflow valve 5 is arranged in the section of the water supply house 2 which extends through the housing 7 .
  • the hose 4 is therefore arranged in front of the inflow valve 5 as seen in the flow direction of the water.
  • the support element 8 has a support section 14 .
  • a mounting portion 15 extends from one side of the support portion 14 .
  • the attachment section 15 is used to attach the support element 8 to a cistern.
  • the fastening section 15 has an external thread 24 on the outside.
  • the water supply channel 2 extends through the attachment section 15 and runs parallel to the external thread 24.
  • the external thread 24 and the attachment section 15 can be guided through an opening in the cistern from the inside to the outside.
  • the support element 8 can then be attached to the cistern with a nut which is screwed onto the external thread 24 .
  • a side wall 16 extends away from another side, which is opposite to the side from which the fastening section 15 projects away from the support element 8 .
  • the side wall 16 further forms part of the said longitudinal guide between the support element 8 and the housing 7.
  • the housing 7 also has a side wall 17 .
  • the side wall 17 extends on the outside over the side wall 16 of the support element 8.
  • the side walls have grooves or elevations which provide the said longitudinal guide 9. In other words, the housing 7 and the support element 8 can be moved together via the side walls 16, 17 due to their mounting.
  • the longitudinal guide 9 preferably has a large number of locking cams which are distributed evenly over the length of the longitudinal guide 9 . A resistance to the displacement of the housing 7 relative to the support element 8 can be achieved via these locking cams. Furthermore, the longitudinal guide 9 can include a locking element with which the housing 7 can be locked to the support element 8 .
  • the two side walls 16, 17 define an interior space 18.
  • the hose 10 is arranged in such a way that it lies essentially completely in the interior space 18. As a result, the hose 10 is guided accordingly through the side walls 16, 17 and is not uncontrolled in the cistern.
  • the output 4 of the water duct 2 is in the sectional views of Figures 3 and 5 shown.
  • the outlet 4 has at least one outlet opening 19 .
  • the outlet opening 19 is directed downwards when viewed in the installed position.
  • the outlet opening 19 is arranged in such a way that the flushing water can leave the water duct 2 in a free jet.
  • the outlet opening 19 is at a certain distance above the water line WL, which is defined by the water surface when the cistern is completely full.
  • the inflow valve 5 is also above the waterline WL. This means that the parts of the housing 7 with the inflow valve 5 and the outlet 4 are above the water line WL when the cistern is at its maximum level.
  • the housing 7 has an opening 20 .
  • the opening 20 and the outlet opening 19 are positioned relative to one another in such a way that the free jet from the outlet opening 19 opens into the opening 20 .
  • the escaping water therefore enters the housing 7, here in the interior 18.
  • the housing 7 and also the support element 8 have corresponding outflow openings 21, through which the flushing water can leave the interior 18 and can flow into the cistern.
  • This indirect introduction of the flushing water has the advantage that the cistern can be filled with little noise.
  • the opening 20 is closed by a guiding element 22 which directs the flushing water which enters the housing 7 to the inside of the side wall.
  • a method for assembling a filling valve 1 in a cistern is characterized in that in one assembly step the height of the filling valve is adjusted by moving the housing 7 relative to the support element 8, the change in length resulting from the relative displacement between the housing 7 and the support element 8 of the water duct 2 is compensated by changing the position of the hose 10 .
