Definitions

  • the invention relates to a siphon for sanitary facilities, in particular for a washstand, with a downpipe connected to the sanitary facility, approximately vertically directed, a downpipe part adjoining the downpipe, forming a U-shaped interior, and a riser pipe adjoining the deflection pipe part an approximately horizontally directed drain connection opening into a drain pipe is connected.
  • a siphon of this type is known as a "tube siphon".
  • the downpipe and the riser pipe as well as the intermediate deflecting pipe part formed as a U-pipe and the drain pipe connecting horizontally to the riser pipe have approximately the same cross-section, which ensures very good drainage of the waste water and settling of impurities or of smaller solid bodies contained in the wastewater, such as sand or other small parts, is not possible.
  • the disadvantage here is that small, unintentionally discharged objects, e.g. Rings, earrings, etc., are irretrievably lost as soon as they get into the downpipe, since these objects are inevitably entrained in the drainage channel with the wastewater flow.
  • pear siphon In the case of a so-called "pear siphon", the entrainment of such objects which accidentally get into the wastewater is prevented, but a pear siphon has a fluidically unfavorable design, since a pear siphon has a high and relatively narrow annular gap between an immersion tube and a cylinder surrounding the immersion tube is that only in one place with the drain pipe in line Connection is established. As a result, large parts of the annular gap are insufficiently flowed through, and impurities are often deposited, so that the pear siphon is often clogged and has to be cleaned.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a siphon which, in terms of flow, corresponds approximately to a tube siphon and has a correspondingly low tendency to become blocked, but which prevents objects from accidentally getting into the waste water.
  • a further task is to be seen in the fact that such bodies or objects settling in the siphon can be removed from it in a simple manner and without requiring a specialist.
  • a particularly simple handling of the insert is achieved in that a plate forming the closure part is fastened to the end wall of the insert by means of a screw connection, an elastically deformable seal being provided between the end wall and the plate.
  • an immersion tube which can be displaced in relation to the latter in its axial direction opens into the drop tube.
  • a stop forming a shoulder for a dip tube to be inserted into the drop tube is advantageously provided at the lower end of the drop tube.
  • a particularly low overall height can be achieved in that the vertical pipe section protrudes into the horizontal part of the drain connector and forms an overflow edge in this drain connector.
  • the siphon has a vertically directed downpipe 1 which merges into an approximately horizontally directed deflecting tube part 3 via a curved part 2.
  • a vertically directed riser pipe 5 is attached to the upper lateral surface 4 of the deflection pipe part 3.
  • Down pipe 1, deflection pipe part 3 and riser pipe 5 are integrally formed.
  • the appropriately cylindrical deflecting tube part 3 has a somewhat larger diameter than the downpipe 1 and the riser tube 5.
  • the downpipe 1 projects into the deflecting tube part 3 up to approximately its horizontal plane through the central axis 6 and thus forms an inner deflecting edge for the flow with its lower edge 7, which projects freely into the inside of the deflecting tube part 3.
  • the riser 5 is provided on the outside with annular recesses 8, which serve to reduce the wall material of the riser 5.
  • One of these recesses 8 serves to receive an elastic ring seal 9 for sealing the cut-to-length drain pipe 11 placed over the riser pipe 5 with a vertical pipe section 10.
  • the pipe section 10 merges with a discharge bend 12 into a horizontal part of the drain pipe 11, the pipe section 10 in protrudes the interior of the horizontal part of the drain connector to reduce the height of the siphon and forms an approximately horizontal overflow edge 10 ⁇ there.
  • the drain pipe 11 protrudes into a wall in which the drain channel, not shown, is walled.
  • the drainage pipe 11 is covered opposite the wall by means of an elastic rosette 13, which enables good coverage even with an oblique connection.
  • the vertical pipe section 10 of the drain pipe 11 is on the riser 5 by means of a snap connection about its vertical axis rotatably attached.
  • the snap connection is formed by a radially inwardly projecting annular bead 14 of the vertical pipe section 10, which engages behind an undercut 15 of the riser pipe 5 on the outside.
  • a trough-like insert 16 is inserted in the deflecting tube part 3, the shape of which is adapted to the inner wall of the deflecting tube part 3.
  • This insert 16 has a cavity 17 which, on the one hand, is connected in line with the downpipe 1 and on the other hand with the riser pipe 5, so that the waste water is forced to flow through the cavity 17 of the insert 16.
  • the end portion 18 of the insert 16 lying under the downpipe 1 is formed in a spoon-like manner in accordance with the arcuate connection of the deflecting tube part 3 to the downpipe 1.
  • the insert 16 projects with its semi-cylindrical wall part 19 adjoining the spoon-like bent end part 18 approximately to the height of the free edge 7 of the downpipe 1 projecting into the deflection pipe part 3, so that the insert 16 is secured against rotation and when inserted into the deflection pipe part 3 is led.
  • the end of the insert 16 lying below the riser pipe 5 is formed by an end wall 20 which is adapted to the cross section of the deflecting pipe part 3 and whose lower, vertically directed section 21 merges into the semi-cylindrical wall part 19 with an inner edge 22, so that the end wall 20 is a baffle for the waste water forms.
  • the upper section 23 of the end wall 20 is inclined such that the end wall leads into the riser pipe 5 without a step.
  • On the outside of the end wall 20 there is an internal thread 24 into which an external thread 25 of an extension 26 of a plate 27 forming a closure part for the deflection tube part 3 can be screwed.
  • a device connection 41 opens, which is connected by a hose nozzle 42 by means of an union nut 43 is attachable to an oblique extension 44 of the immersion tube 35, and a non-return valve 45 used in this extension 44 is formed.
  • the non-return valve 45 is designed as a separate component which is sealingly inserted into the shoulder 44 and has an overflow edge 46 which is bevelled against the immersion tube 35 and is covered by a rubber flap 47.
  • an installation 48 which deflects this waste water downward is provided in the interior of the immersion pipe 35.
