Definitions

  • the present invention relates to a waste fitting according to the preamble of claim 1.
  • Drain fittings for triggering flushes from a cistern are known from the prior art.
  • drain fittings have become known for selectively triggering a full flush or partial flush.
  • a weight body is arranged, which can optionally be switched on the valve body.
  • a drain fitting for a cistern comprises a valve body with a valve seat cooperating sealing element and a float, wherein the valve body is movable with the sealing element from the valve seat along a central axis from a rest position to a scavenge and from the scavenge to the rest position, and a float chamber having an opening through which the valve body extends therethrough Float within the float chamber along the central axis is movable and cooperates hydraulically with the float chamber.
  • the float chamber includes at least one control passage through which, as soon as a flushing water level surrounding the drain assembly has dropped to the level of the control passage, air from areas outside the float chamber may enter the float chamber such that the pressure ratios between the float chamber and the areas outside the float chamber can be compensated, wherein the float is movable in balancing the pressure conditions of the scavenge in the rest position.
  • a central axis extends centrally through the float chamber.
  • the valve body is laterally offset from the float chamber arranged such that the central axis is located with a transverse offset to the central axis of the float chamber.
  • the outer shape of the waste set can be optimized.
  • a space region is created in which further functional elements for controlling the flushing quantity can be arranged.
  • the flexibility for adjusting the purge amount is increased because of space for the arrangement of the functional elements is created.
  • valve seat is also arranged laterally offset from the float chamber.
  • the valve seat is particularly preferably arranged with the same offset as the valve body to the float chamber. In this way, a symmetrical arrangement between the valve seat and the valve body can be achieved, wherein the float chamber is laterally offset from the valve seat and valve body.
  • said central axis and said central axis are parallel to each other. In installation position, the central axis and the central axis are in the vertical.
  • the central axis preferably runs centrally through the valve body.
  • the smallest distance transverse to the central axis or to the central axis between the chamber wall of the float chamber and the valve body is less than 2 millimeters, in particular less than 1 or 0.5 millimeters. This means that the valve body is arranged very close to the chamber wall of the float chamber.
  • the smallest distance is preferably always such that there is always a small clearance between the chamber wall and the valve body.
  • the float chamber extends eccentrically around the valve body as seen from the location of the smallest distance.
  • the float chamber down towards a partition, which lies above the sealing element.
  • the partition closes the float chamber downwards or provides a limitation of the float chamber.
  • the partition wall has an opening through which the valve body extends.
  • the opening and the valve body are preferably dimensioned to each other such that there is clearance between the valve body and the opening. Through this game, water can enter the float chamber when the cistern is filled.
  • the valve body may have a recess which is arranged such that the indentation comes to lie at the level of the partition when the valve body is in the rest position.
  • the cross section of the float chamber is seen in the direction of the central axis, substantially constant over the entire height. This allows a uniform and continuous movement of the valve body can be achieved over the entire height of movement.
  • the float chamber thus preferably has a circular cylindrical cross section, wherein the valve body arranged eccentrically to this circular cylindrical cross section is.
  • a reservoir is present above the float chamber, which leads to a breakthrough in the float chamber, such that when lowering water level in the cistern from the reservoir water runs after the water in the float chamber.
  • running water a possible loss of water in the float chamber downwards, in particular along the valve body, can be compensated.
  • the breakthrough has a diameter of a few millimeters.
  • the breakthrough is at an altitude that is well above the highest position of the float.
  • the control passage for the initiation of a first purge is formed with a first purge quantity.
  • the drain fitting comprises a control unit for controlling a second flushing quantity. Upon reaching a water level intended for the second flushing quantity, the control unit provides a closing force on the valve body with a closing weight, wherein the closing force can be switched by the control unit onto the valve body via a switching element.
  • control unit is arranged substantially in the spatial region resulting from the transverse offset laterally to the float chamber.
  • control unit is located laterally in the area in which the distance between the float chamber and the valve body is minimal. That is, the control unit is in the space area created by the above-described offset.
  • the control unit represents in the present case said functional element.
  • control unit is preferably located with respect to the float chamber substantially on the opposite side of the maximum extent of the float chamber.
  • control unit is located with respect to a transverse direction to the central axis or to the central axis completely in a circular geometric cylinder which extends around the central axis and extends through the maximum extent of the float chamber therethrough.
  • the closing weight of the control unit is arranged transversely to the central axis with respect to the float chamber and can move up and down in addition to the float chamber.
  • the closing weight is thus preferably in said space area, in particular in the geometric circular cylinder.
  • the switching element When the control unit is raised, the switching element preferably automatically engages with the valve body in a latching connection.
  • control unit further comprises a bearing rod.
  • the switching element is arranged at a lower end of the bearing rod.
  • the closing weight is fixedly mounted on the bearing rod or relative to the bearing rod.
  • the height position of the closing weight is adjustable over an adjustment range. This means that the closing weight can be moved over the setting range. At a higher level, less water is removed during the flushing process than at a lower level.
  • the first purge is a full rate purge and the second purge is a partial purge. This means that when 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 purge is a partial purge and the second purge is a full-flush. This means that when the closing weight is activated, a full flush is triggered and when the control passes through the water level, a partial flush is triggered.
  • the drain fitting further comprises at least one closure element with which one of the control passages are releasable and the other of the control passages are closed.
  • the closure element is preferably a slide, which is movably mounted on the outside of the drain fitting.
  • the adjustment range of the closing weight extends in height at least to below the uppermost control passage.

  • the float chamber 6 comprises at least one control passage 7 through which, as soon as a flushing water level S surrounding the waste set 1 has sunk at the level of the control passage 7, air can enter the float chamber 6 from areas 8 outside the float chamber 6, such that the pressure conditions between the float chamber 6 and areas 8 outside the float chamber 6 are compensated. In this compensation, the float 5 is movable from the scavenge to the rest position.
  • the float chamber 6 is designed to be circular cylindrical around a central axis Z here.
  • the central axis Z extends centrally through the float chamber 6 therethrough.
  • the valve body extends substantially along a central axis M and is designed to be movable in the direction of this central axis M.
  • the valve body 2 is arranged laterally offset to the float chamber 6 such that the central axis M is at a transverse offset to the central axis Z of the float chamber 6.
  • the transverse offset is denoted by the reference Q.
  • a spatial region arises in the region of the reference symbol R in which a control unit 12 can be arranged in the embodiment shown.

  • the control unit 12 is arranged substantially laterally relative to the float chamber in the space region R resulting from the transverse offset, or the control unit 12 lies substantially on the opposite side of the maximum expansion Amax of the float chamber 6 with respect to the float chamber 6.
  • valve seat 3 is also arranged laterally offset to the float chamber 6.
  • the valve seat 3 is here below the valve body. 2
  • the smallest distance A transverse to the central axis M or to the central axis Z between the chamber wall 9 of the float chamber 6 and the valve body 2 is preferably less than 2 millimeters, in particular less than 1 or 0.5 millimeters. That is, the distance is very small, which is for the greetings of the space R advantage. However, the distance is preferably such that a contact between the chamber wall 9 and the valve body 2 takes place. This means that there is always a clearance between the chamber wall 9 and the valve body 2.
  • control unit 12 is located completely in a geometric circular cylinder with respect to a transverse direction to the central axis or to the central axis, which extends around the central axis M and extends through the maximum extent of the float chamber.
  • the maximum extent in the transverse direction is in the FIG. 4 can be seen where this is marked with a dash K.
  • the line K thus forms the diameter of the circular cylinder about the central axis.
  • a dash K ' is shown, which shows the other side boundary of the circular cylinder.
  • the float chamber 6 has a partition wall 10, which above the sealing member 4 is located, wherein the partition wall 10 has an opening 25 through which the valve body 2 extends therethrough.

  • the sealing element 4 rests on the valve seat 3.
  • the float 5 Upon initiation of a first flush, the float 5 is raised via an actuating portion 22. Due to the Cooperation between the float 5 and the float chamber 6 remains the float 5 in its scavenge. The float 5 remains in its flushing until the rinse water level on the in the FIG. 2 marked level is lowered. Upon reaching this level, air can enter through the control passage 7 in the float chamber 6 and the hydraulic balance between the float 5 and the float chamber 6 is disturbed, causing the float 5 is lowered in the direction of valve seat 3 from the scavenge to the rest position.
