Definitions

  • the present invention relates to a drain fitting according to the preamble of claim 1.
  • Drain fittings for triggering flushes from a cistern are known from the prior art.
  • drain fittings for the optional triggering of a full flush or partial flush have become known.
  • the EP 0 722 020 such a flushing device.
  • a weight body is arranged for partial flushing, which can optionally be connected to the valve body.
  • a drain fitting for a cistern comprises a valve body with a sealing element cooperating with a valve seat and a float, the valve body with the sealing element moving from the valve seat along a central axis from a rest position to a flushing position and from the flushing position is movable into the rest position, and a float chamber with an opening through which the valve body extends and is movably mounted therein, wherein the float is movable within the float chamber along the central axis and cooperates hydraulically with the float chamber.
  • the float chamber comprises at least one control passage through which, as soon as a flushing water level surrounding the drain fitting has sunk to the level of the control passage, air from areas outside the float chamber can enter the float chamber, so that the pressure conditions between the float chamber and the areas outside the float chamber can be equalized
  • the float can be moved from the flushing position to the rest position when the pressure conditions are equalized.
  • the float chamber has a base section extending completely around the central axis and a snorkel section adjoining the base section.
  • the cross section of the snorkel section seen transversely to the central axis is smaller than the cross section of the base section.
  • the float extends with a column section into the snorkel section.
  • the control passage is designed to trigger a first flush with a first flush quantity.
  • the drain fitting also includes a control unit for controlling a second flush volume.
  • the control unit When a water level intended for the second flush volume is reached, the control unit provides a closing force on the valve body with a closing weight, the closing force being switchable to the valve body via a switching element from the control unit.
  • Extending the swimmer into the snorkel section has the advantage that, with the increased volume of the swimmer, the proportion of water that presses on the swimmer in the swimmer chamber can be reduced, so that the noise generated during the closing process can be reduced.
  • the volume of the float chamber can be increased without the structural size of the drain fitting or its function being adversely affected. This has the advantage that a simplified optimization of the closing process is made possible due to the increased volume.
  • the float preferably has a lower section, the lower section being essentially circular-cylindrical and in the flushing position preferably filling or essentially filling the base section of the float chamber.
  • the column section is preferably designed as a float.
  • the column section like the lower section, is particularly preferably designed essentially as a cavity filled with air.
  • kel section is understood to mean a section which supplements the base section towards the top in the installed position.
  • the base section is preferably designed as a circular cylinder.
  • the snorkel section preferably lies within the maximum diameter of the base section as viewed in the direction of the central axis.
  • the external shape of the float with the lower section and the column section and the internal shape of the float chamber with the base section and the snorkel section are such that the float can be moved in the float chamber.
  • the two shapes are designed to essentially match one another, possibly with play to one another.
  • the column section preferably fills the cross section of the snorkel section essentially completely or at least 55%, in particular at least 75%, when viewed in cross section transversely to the central axis. This means that the column section extends essentially completely or almost completely over a large part of the cross section of the snorkel section when viewed transversely to the central axis.
  • the column section preferably fills the volume of the snorkel section essentially completely or to at least 55% or at least 75% when the swimmer is in the flushing position.
  • “essentially completely” means that the column section and snorkel section are relative to one another in such a way that a residual amount of water is always present between the column section and snorkel section.
  • the aforementioned designs have the advantage that the proportion of water which presses on the float when the float moves from the flushing position to the rest position can be kept small.
  • the column section and the snorkel section are laterally offset from said central axis to the central axis. That is, the snorkel section is arranged eccentrically to the lower section and the column section is arranged eccentrically to the base section.
  • the float chamber that is to say the snorkel section and the base section, apart from the at least one control passage, is preferably designed to be completely closed with a side wall up to an end wall.
  • the float chamber is open at the bottom.
  • the bearing opening, in which the valve body is movably supported, is preferably present in the end wall.
  • At least one of the outer sides of the column section preferably runs at an angle to the central axis.
  • the inclination is such that the cross section of the column section becomes smaller with increasing distance from the base section or the lower section.
  • the snorkel section and the column section preferably have the cross section of a ring segment, each with an inner radius and an outer radius.
  • the opening angle of the ring segment is preferably a maximum of 180 °, in particular a maximum of 145 °, particularly preferably a maximum of 90 °.
  • the radii are chosen such that the column section can protrude into the snorkel section.
  • the outer radius of the base section is preferably equal to the outer radius of the snorkel section. This means that the snorkel section does not extend further out than the base section with respect to the transverse direction to the central axis.
  • the snorkel section viewed from the upper end of the float chamber, preferably has a height which is greater than the height of the base section. In this way, a compact design of the base section or the drain fitting can be achieved.
  • the snorkel section apart from the at least one control passage and the transition to the base section, is preferably designed to be closed on the reverse side.
  • the switching element When the control unit is raised, the switching element preferably automatically engages in a latching connection with the valve body.
  • the height of the closing weight is preferably designed to be adjustable over an adjustment range. This means that the closing weight can be moved over the setting range. In a higher position, less water is removed during the rinsing process than in a lower position.
  • the first flush is a full flush and the second flush is a partial flush.
  • the closing weight is activated, a partial flush is triggered and when the control passage through the water level is reached, a full flush is triggered.
  • the first flush is a partial flush and the second flush is a full flush. This means that when the closing weight is activated, a full flush is triggered and when the control passage through the water level is reached, a partial flush is triggered.
  • a plurality of control passages are preferably arranged at different heights, the drain fitting further comprising at least one closure element with which one of the control passages can be released and the other of the control passages can be closed.
  • the closure element is preferably a slide which is movably mounted on the outside of the drain fitting.
  • At least one of the control passages is preferably arranged in the snorkel section, the other of the control passages, if any, being arranged in the snorkel section and / or in the base section.
  • the height of the adjustment range of the closing weight preferably extends at least to below the uppermost control passage. In this way, the heights between the control unit and the control passage can be superimposed, which increases the flexibility of setting the water extraction.
  • the control unit is preferably arranged opposite the snorkel section and can move up and down next to the snorkel section.
  • the snorkel section preferably comprises a ventilation element for ventilation when the float chamber is filled.
  • a drain fitting 1 for a cistern is shown.
  • the drain fitting 1 comprises a valve body 2 with a sealing element 4, which works together with a valve seat, and a float 5.
  • the valve body 2 is with the sealing element 4 from the valve seat 3 along a central axis M from a rest position to a flushing position and from the flushing position to the Movable rest position. In the flushing layer, water can flow off through the gap between the valve seat 3 and the sealing element 4.

  • the float chamber 6 has an opening 28 through which the valve body 2 extends.
  • the valve body 2 is movably supported in the opening 28.
  • the float 5 can be moved essentially within the float chamber 6 along the central axis M and works hydraulically with the float chamber 6.
  • the float chamber 6 comprises at least one control passage 7 through which, as soon as a flushing water level S surrounding the drain fitting 1 has dropped to the level of the control passage 7, air from areas 8 outside the float chamber 6 can enter the float chamber 6, such that the Pressure conditions between the float chamber 6 and areas 8 outside the float chamber 6 can be compensated. With this compensation, the float 5 or the valve body 2 can be moved from the flushing position into the rest position.
  • the float chamber 6, apart from the at least one control passage 7, is designed to be completely closed laterally up to an end wall 19 with a side wall 31.
  • the control passages 7 penetrate the side wall 31.
  • the side wall 31 delimits the base section 9 and the snorkel section 10 to the outside.
  • the opening 28 is located in the end wall 19.
  • the float chamber 6 is open at the bottom.
  • the float chamber 6 comprises a circular cylindrical base section 9 extending completely around the center axis M and a snorkel section 10 adjoining the base section 9.
  • the snorkel section 10 adjoins the base section 9. In the installed position, the base section 9 lies below the snorkel section 10 and the snorkel section 10 above the base section 9. It can also be said that the snorkel section 10 extends the float chamber 6 from the base section 9 upwards.
  • the snorkel section 10 is delimited at the top by the end wall 19.
  • the cross section of the snorkel section 10 seen transversely to the central axis M is smaller than the cross section of the base section 9.
  • the volume of the snorkel section 10 is preferably smaller than that of the base section 9.
  • the float 5 extends with a column section 11 into the snorkel section 10.
  • the volumes relevant for the lift and the lowering are optimally used and the movement of the valve body 2 can be optimized.
  • the float preferably has a lower section 29 which can be moved up and down in the base section 9.
  • the lower section 29 is designed essentially as a circular cylinder.
  • Both the lower section 29 and the column section 11 are each designed as a cavity in the embodiments shown, so that they one in the water Experience a boost.
  • the cavity provided by the two sections can be filled with air.
  • the cavity is open at the bottom. It can also be designed as a closed cavity
  • the column section 11 seen in cross section transversely to the central axis M, essentially fills the cross section of the snorkel section 10.
  • the degree of filling is preferably at least 55% when the column section 11 is in the flushing position with the float 5.
  • the column section 11 can also fill the snorkel section 10 to at least 75% or substantially completely.

This means that the inner shape is the same or similar to the outer shape. As mentioned herein, it is advantageous if there is play between the inner shape and the outer shape.
  • the lower section 29 of the float extends concentrically around the central axis M, while the column section 11 of the float 5 is arranged offset from the central axis M. It can also be said that the column portion 11 is arranged eccentrically to the lower portion.
  • the lower section 29 is penetrated here by an overflow pipe 30 along the central axis M.
  • the column section 11 is arranged laterally offset from the overflow pipe 30.
  • the float 5 is in the rest position.
  • the sealing element 4 rests on the valve seat 3.
  • the float 5 with the valve tube 2 is raised via an actuating section 22. Due to the interaction between the float 5 and the float chamber 6, the float 5 remains in its flushing position.
  • the float 5 remains in its flushing position until the flushing water level S reaches that in the Figure 5 drawn level is lowered.
  • air can enter the float chamber 6 through the control passage 7 and the hydraulic equilibrium between float 5 and float chamber 6 is disturbed, whereby the float 5 lowers in the direction of the valve seat 3 from the flushing position to the rest position.
  • the column section 11 is designed such that when the valve body 2 is in the flushing position, its upper end 18 is spaced apart from the end wall 19 of the snorkel section 10. Because of this distance, there is then a certain amount of residual water in the float chamber 6. However, the distance must not be too great, otherwise the closing noises increase.
  • Both the snorkel section 10 and the column section 11 have in FIG embodiment shown on the cross section of a ring segment.
  • the ring segment has an inner radius Ri10, Ri11 and an outer radius Ra10, Ra11.
  • the opening angle of the ring segment is preferably a maximum of 180 °. A maximum of 140 ° or 90 ° is particularly preferred.
  • the formation of the snorkel section 10 and the column section 11 with the corresponding opening angle has the advantage that parts of the control unit 12, in particular the closing weight 13, can extend downward next to the snorkel section 10. This means that parts of the control unit 12 can move up and down next to the snorkel section 10.
  • the snorkel section 10 has a height H10 as seen from the upper end of the float chamber 6.
  • the height H10 is greater than the height H9 of the base section 9. As a result, the movement path of the control unit 12 can be increased further.

  • the first flush amount is preferably a full flush amount and the second flush amount is preferably a partial flush amount.
  • control passages 7 are arranged.
  • the control passages 7 are at different heights.
  • a first control passage 7 lies in the area of the upper end of the snorkel section 10.
  • Further control passages 7 are arranged in the snorkel section 10 and in the base section 9. In other words, in the embodiment shown, the height of the control passages 7 is distributed over the base section 9 and the snorkel section 10.
  • the drain fitting 1 further comprises at least one closure element 16, with which one of the control passages 7 can be released and the other of the control passages 7 can be closed. This means that an installer can use the closure element to define which of the control passages 7 is to be the active control passage. The other control passages 7 are then appropriately sealed watertight or airtight.
  • At least one of the control passages 7 is therefore arranged in the snorkel section 10.
  • the other control passages 7 are arranged either in the snorkel section 10 or in the base section 9.
  • the closing weight 13 can be adjusted via an adjustment range 15. That is, the closing weight 13 can be adjusted in height. This allows the corresponding amount of flushing water to be defined.
  • the height of the adjustment area 15 preferably extends at least as far as below the uppermost control passage 7. This allows the amounts of flushing water to be superimposed.
  • the snorkel section 10 furthermore has a ventilation element 17. This allows air to flow out into the cistern when the cistern is filled.
  • control unit 12 furthermore comprises a bearing rod 24, the closing weight 13 being mounted on the bearing rod so as to be adjustable relative to the bearing rod 24.
  • the switching element 14 is switched on via a correspondingly designed control surface 25, which is arranged here on the housing in the area of the float chamber 6.
