Definitions

  • the invention relates to an odor trap for tubs, basins and the like, which has an upper part which can be inserted into the drain opening from the inside of the basin and a lower part which projects beyond the underside of the basin.
  • odor traps are usually also referred to as siphons.
  • the siphon usually consists of 4 parts (FIGS. 1 and 2): the siphon lower part 4, the siphon upper part 3, the seal 31 and the screw 5.
  • a threaded insert 51 is provided, in which the screw 5 from the upper part 3 is screwed in to attach the siphon to the basin or the tub.
  • the assembly is very complex, in that the seal 31 is first inserted into the siphon lower part 4 in the groove provided and both parts are placed on the opening on the underside of the basin. From the top of the tub, the siphon top 3 is now inserted through the opening of the tub. With the screw 5 arranged centrally in the upper part 3, the lower and upper part of the siphon are connected to each other and the seal 31 between the lower part of the siphon 4 and the underside of the tub axially pressed. This ensures that the siphon is tightly connected to the tub and that no medium can escape from the gap.
  • the construction described requires that the lower siphon part 4 is to be provided with a threaded insert 51, which allows the lower siphon part to be screwed to the upper siphon part.
  • the manufacture of the siphon lower part 4 as a plastic injection-molded part is made more difficult because the threaded insert 51 has to be inserted into the mold manually or mechanically before the injection process. This measure not only requires complicated mechanical equipment, but also significantly increases the cycle time for the spraying process.
  • Another disadvantage of this construction is that individual parts have to be assembled and screwed on-site when installing the siphon.
  • the object of the invention is to avoid the disadvantages described and to create a siphon that is composed of a few parts that are easy to manufacture and assemble.
  • the siphon consists of only two parts, namely the upper and the lower part.
  • the upper and lower siphon parts are connected to each other by joining one another, additional parts are not necessary for this.
  • the screw and the threaded insert are eliminated.
  • the manufacture is also considerably simplified as a result.
  • a particular advantage is that the siphon is pre-assembled
  • the module or module can be added to the basin or the tub when it is shipped. This also ensures that there are no errors during on-site assembly by assembling individual parts in the wrong place or forgetting them during installation.
  • a siphon is connected to the distribution trough 1, with an upper part 6, a lower part 7, which opens into a drain line 71.
  • the siphon according to the invention consists of an upper part 6, which has a cylindrical extension 61, with which the upper part 6 is inserted into the lower part 7 by a press connection and is thereby connected to the lower part 7.
  • the cover 62 of the upper part 6 has an annular extension 63, which projects beyond the cylindrical extension 61 in diameter, so that it connects to the inside diameter of the drain opening 12 of the tub 1.
  • the lower part 7 has a catch 72 near its upper free end, which surrounds the lower part 7 in a ring shape with a bevel 73.
  • This catch can be a continuous ring, but it can also be interrupted.
  • an annular space is formed with this annular catch 72 with the annular extension 63 of the upper part 6 when the upper part 6 is inserted into the lower part 7.
  • This annular space serves to receive a seal 32, which is an O-ring seal in the embodiment shown.
  • the siphon is preassembled as a unit and can be packed with the delivery of the tub 1 in this state and finally inserted into the tub at the installation site.
  • a connection piece 11 is therefore formed on the outlet opening 12 of the tub 1, which has a groove 33 for receiving the seal 32 and an annular collar 13 which engages over the catch 72 on the circumference of the lower part 7 inserted into the outlet opening 12, so that the siphon is held down when installed.
  • the bevel 73 of the catch 72 plays a role, since it additionally pushes the seal 32 into the groove 33, but the catch 72 does not get past the seal 32 if the siphon is in the direction of the Inside the pelvis is loaded.
  • the siphon is secured against further downward movement by the collar 13 and the catch 72.
  • the seal 32 between the lower part 7 and the connecting piece 11 of the tub 1 seals the siphon so that the water flowing out of the tub 1 into the drain line 71 cannot escape at the connection point of the siphon.
  • the seal 32 thus has the task of sealing the siphon to the tub 1, on the other hand, however, it also has the function of fixing the siphon in the mounting geometry of the tub in the axial direction.
  • the seal 32 is elastically pressed in the radial direction by the appropriate choice of the diameter of the lower part 7 and the groove 33 when mounting the siphon on the tub 1. If the siphon reaches the collar 13 with the catch 72, then the seal 32 of the siphon relaxes again somewhat in the radial direction, since it can escape into the groove 33 on the connecting piece 11 of the tub 1. This ensures that the siphon is sealingly connected to the tub 1 and fixed in the axial direction.
  • the siphon thus remains fixed in the axial direction even when the drain pipe 71 is installed, even if an axial force is applied to the siphon from below.
  • the seal 32 effectively prevents loosening of the connection, as already described above.
  • the siphon itself consists only of two simple plastic parts, in the manufacture of which no slides or lost cores are required. This considerably cheapens the manufacturing process.
  • the siphon according to the invention can be used not only in simple tubs, shower and bath tubs and the like. are used, but can be used in the same way with advantage in basins or tubs with overflow. It is also not necessary that the upper part 6 must be inserted into the lower part 7. 5 shows, the lower part 8 can also be inserted into the cylindrical projection 91 of the upper part 9.
  • the Basin 20 has an integrally formed connecting piece 201 with an annular collar 203 and a groove 33 for receiving the seal 32.
  • an annular space 204 is provided which is connected to the overflow.
  • the siphon is connected to this annular space 204 through openings 94 in the lower part 9.
  • the drain opening 22 of the basin 20 is connected to the drain line 81 via the siphon.
  • the cover 92 of the upper part 9 has an annular extension 93, which connects to the drain opening 22 and is adapted in accordance with its bevel.
  • This siphon is also delivered as a preassembled module by pressing the upper part 9 and lower part 80 into one another and is inserted into the drain opening 22 with the inserted seal 32 during assembly on the basin.
  • the siphon is fixed in the axial direction by the annular catch 82, which is supported on the collar 203, and the bevel 83.
  • the seal 32 is under axial pressure to seal the siphon against the basin, the seal also permitting an axial upward movement only with great effort, as already described in the embodiment according to FIG. 4.
  • the siphon cannot be used as a preassembled unit from one side into the drain opening 22 of the basin 2, but here too the upper part 90 is inserted into the lower part 80 with a cylindrical projection 901 and thereby connected to it.
  • the siphon only consists of an upper and a lower part.
  • the basin 2 has a cylindrical connecting piece 21, in which an annular space 24 is formed, which is connected to the overflow 25.
  • the upper part 90 has a cover cap 902, on which an elastic ring extension 903 is provided, by means of which an axial clamping force can be generated. Furthermore, a groove 905 can be provided for receiving a seal 32 which is supported radially against the basin 2.
  • the cylindrical extension 901 has openings 904 so that the medium flowing out of the overflow 25 into the annular space 24 can flow off via the siphon.
  • a hook-like extension 906 is provided on the cylindrical extension 901, which engages in an annular groove 804 on the inner circumference of the lower part 80 when the upper part 90 is fitted into the lower part 80. Since the lower part 80 has an elastic ring shoulder 803, which is supported on the end face of the connecting piece 21, an axial tension is generated by the latching of the hook 904 in the annular groove 804, which presses the elastic ring extension 903 against the edge of the drain opening 22, whereby this contact pressure is absorbed by the elastic collar 803 on the lower part 80. In this way, an extremely stable fixation of the siphon on the basin 2 is achieved, which is able to absorb larger forces that occur during the assembly of the drain pipe.
  • a groove 833 is provided near the free end, which receives a seal 32 which is pressed against the inner diameter of the connecting piece 21 as soon as the lower part 80 is inserted with this seal into the drain opening 22 from below.
  • the hook-like extension 906 can be slotted as a ring or can also be provided with individual hooks which are resiliently movable in the radial direction in order to be able to snap into the groove 804.
  • connections e.g. clip connections
  • connections are also conceivable that can absorb an axial tension between the upper and lower part in order to fix the siphon in the drain opening of the basin.
  • the seal 32 between the upper part 80 and the basin may also be omitted.
  • a groove for receiving the seal 32 can also be provided in the connecting piece 21 of the basin 2, as already according to the embodiment.
  • Fig. 5 shown. 6 has the advantage, however, that it can be equipped with the siphon according to the invention without special measures on the basin itself.
