  • the sealing body, the sealing function against malodorous gases from the at the drain no longer meet the subsequent sewage pipe. In this case, it comes to an odor nuisance.
  • the WO 2015/026207 A1 discloses an odor trap for a drain for sanitary liquid comprising an inlet containing at least one opening for a drain for plumbing liquid, a tubular drain connecting with an upper end to the inlet, a lower end of the tubular drain for the discharge of sanitary liquid and a sealing body in Form of barrier liquid, which is at least partially disposed in the tubular drain.
  • the present invention is therefore based on the object to provide an improved odor trap for a Sanitär thoroughlykeitsabpound, which allows a reliable seal against odors and permanently allows the outflow of large quantities of sanitary liquid with minimal drainage diameter.
  • the odor trap for a sanitary liquid drain in particular for a urinal, contains an inlet with at least one opening to a drain pipe, which allows the drainage of the sanitary liquid.
  • the drain pipe forms a tubular drain, which connects with an upper end to the inlet.
  • the sanitary fluid flows through the tubular drain and exits from a lower end of the tubular drain.
  • the sanitary liquid contains at least one of the components from the group urine, water or cleaning fluids. Underwater is understood as any form of used water, rinse water but also drinking water. In particular, all components of the sanitary liquid can be supplied to a sewage system in order to be treated in a sewage treatment plant.
  • the sanitary liquid drain trap includes an inlet containing at least one sanitary liquid drain port, a tubular drain connecting with an upper end to the inlet. A lower end of the tubular drain allows the sanitary liquid to exit.

  • the sealing body has a jacket which has an outer surface whose cross-section widens to a maximum cross-section in a series of sectional planes which are defined by the inlet-side fastener to an opposite end normal to the longitudinal axis of the outlet through the jacket.
  • the distance of the outer surface of the shell of the sealing element from the inner wall of the tubular drain at the location of the maximum cross section is at least 0.005 mm and at most 1 mm. In this area, due to the small distance between the sealing body and drain can hold an amount of liquid that leads to a gas-tight seal the odor trap.
  • the distance of the shell at the location of the maximum cross section may be 0.01 to 0.5 mm.
  • a shield-shaped sealing body is arranged according to one embodiment.
  • the umbrella-shaped sealing body extends from the inlet-side fastening element in the direction of the lower end of the tubular drain.
  • the sealing body is at least partially disposed in the tubular drain, wherein the sealing body fills a part of the cross section of the drain.
  • the flow cross-section can be increased by the casing of the sealing body forming wrinkles, so that a flow cross-section adapted to the feed quantity is released.
  • the jacket can have a variable wall thickness at least in the region of the maximum cross-section transverse to the main flow direction, whereby such wrinkling can be promoted.
  • the wall thickness of the sealing body can be variable along the circumference of the sealing body.

  • the sealing body in cooperation with the liquid which fills the gap between the outer surface of the sealing body and the inner wall of the tubular outflow, at least in the area of the maximum cross section, forms the sealing zone spanning the outflow cross section.
  • the sealing zone is maintained by the interfacial tension and by adhesion forces between the sealing body, the inner wall and the sanitary residual water, so that a gas-tight seal of the odor trap is possible.
  • the sealing body When entering sanitary liquid, eg urine, into the odor trap from the inlet side, the sealing body is displaced or radially deformed by the sanitary liquid in such a way that a drainage cross-section is created for the sanitary liquid and the sanitary liquid can flow out through the odor trap.
  • the deformability of the sealing body allows that even very small amounts of sanitary liquid or even individual drops can pass through the trap.
  • the sealing body is only just so much displaced by the effluent sanitary liquid that no sewerage odors can pass the trap.
  • the gap additionally reduces sticking of the sealing body to the drain and thus the probability of failure.
  • a band-shaped section can allow an even better and more reliable sealing, since a wider liquid column can be formed in the gap, which can still seal the tubular drain in a gastight manner, for example even in the event of slight contamination in the region of the gap.
  • the sealing body has a cut or slot or a plurality of cuts or slots in the shell at the end or in the band-shaped section.
  • the end may comprise at least one end element from the group of flap-shaped projections, the serrated, teardrop-shaped, wave-shaped or trapezoidal jacket elements. At least a part of the end elements can be arranged in a scale shape one above the other.
  • the subdivision of the sealing area by cuts in smaller sections prevents interference, for example. By sticking in an area that the entire odor trap fails. If the closure elements are adjacent to each other or one above the other, the individual sub-elements are moved radially inwardly when flowing through with sanitary liquid. This movement can cause a mechanical friction between the individual sub-elements, whereby a self-cleaning of the sealing body and the inner wall of the tubular drain takes place.

  • the cross section can increase continuously up to the maximum cross section.
  • the jacket of the sealing body may have the shape of a ball, a dome, a cone, an ellipsoid or a drop.
  • the sealing body may be formed as a hollow body. The The shape of the sealing body essentially corresponds to the shape of the tubular outflow, so that a gap with an essentially constant gap width remains between the outer surface and the inner wall of the tubular outflow.
  • the sealing body contains at least at the end or in the region of the band-shaped portion an elastic material.
  • the elasticity or dimensional stability of the sealing body is decisive.
  • the elasticity of the sealing body is determined by the material used and its shape.
  • the sealing body may contain a urine and detergent-resistant plastic from the group of silicones, thermoplastic elastomers (TPE), ethylene-propylene-diem rubbers (EPDM), polyethylenes (HDPE).
  • a sealing body which projects beyond the lower end or the lower edge of the drain
  • a sealing body with a spherical, spherical, conical, ellipsoidal or teardrop shape can be used.
  • the use of a shield-like half body prevents gases rising from the sewage system from displacing the sealing body and passing the odor trap.
  • a half-body in an upper part preferably one of the previously described forms and has one end preferably at the point with the largest circumference of the sealing body with a circumferential edge on the underside of the half body, that is, the end spans a flat surface ,
  • a sealing body lying in the tubular outflow of the exhaust gases rising from below with pressure from the drainage pipe, which may in particular contain sewage odors is inflated similarly to a parachute and forced against the tubular outflow, whereby an additional sealing effect against a passage of exhaust gases is achieved.
  • the sealing body is made in the region of the end or band-shaped section of an elastic and / or thin-walled material and / or the drain comprises an elastic element at least in the region of the lower end.
  • elastic, thin-walled materials becomes one allows full fit of the sealing body to the tubular drain when the trap is exposed to a gas pressure. This results in a gas-tight closure of the outflow against gas pressure from the outlet side of the tubular drain, which is usually formed by a drain pipe with siphon.
  • an elastic, thin-walled material can easily be displaced radially outward by flowing sanitary liquid. With inflow of sanitary liquid, therefore, the flow area is increased.

  • the diameter of the sealing body at the location of the maximum cross section is smaller than the diameter of the tubular outflow.
  • the axial length of the drain is preferably 10 mm to 50 mm, more preferably 20 mm to 35 mm and the diameter of the drain is preferably 10 mm to 50 mm, particularly preferably 20 mm to 35 mm. Due to the low height of the odor trap this can be used to save space in different sanitary facilities. It is also possible, for example, to equip tubless shower cubicles in buildings or sanitary facilities on ships with corresponding stench traps. Also, such odor traps in sink be used, which means there is less space below the sink for the drain.
  • the sealing body is connectable by a fastening element with the inlet.
  • the fastening element may be formed as part of the sealing body.
  • the sealing body may have a wall thickness which reduces towards the end, wherein the wall thickness at the end of 0.01 mm to 1 mm, preferably 0.1 mm to 0.5 mm.

  • an inlet element merging of residual amounts of water is favored, whereby the sanitary liquid can pass the odor trap faster and more reliable, because radially inwardly directed wrinkles form.
  • deposits on the sealing body and the odor in the odor trap are reduced and it can flow both small, as well as large quantities of sanitary liquid through the tubular drain. Due to the inlet element, wrinkling can take place when liquid flows in, so that the jacket of the sealing body has a wave shape.
  • the inlet element can be formed by reducing the thickness of the jacket on the sealing body, whereby wrinkling can be promoted with increased liquid volume.
  • the inlet element can direct smallest amounts of liquid into the sealing zone.
  • the sealing zone can remain permanently through the formation of condensate.
  • the formation of the condensate takes place by temperature differences between the inlet side and the outlet side of the odor trap. Due to these temperature differences, the moisture content of the air varies, which favors condensation on the sealing body. Inside the drainpipe downstream of the sealing body, it is usually very humid and warm. If it is colder on the inlet side, a condensation takes place on the sealing body, which promotes the maintenance of the sealing zone.
  • a higher pressure is applied to the sealing body in the interior of the drain pipe than on the inlet side of the sealing body. This higher pressure assists in maintaining a gas-tight seal of the tubular drain, so that it can be safely avoided that bad odors from the drain pipe can reach the inlet side of the sealing body to spread in the space in which the odor trap is located.
  • a fastening system in the form of a rotary, point or bayonet closure is provided at the upper end, with which the odor trap can be fastened in a sanitary liquid drain.
  • the fastening system knows fasteners such as knobs, beads or grooves, which engage in a corresponding counterpart of the sanitary liquid drainage. Due to the optional design of the fastening system at the upper end of the tubular drain, a precise positioning of the odor trap within the Sanitärillonkeitsabhnes and thereby a gas-tight closure be guaranteed.

  • the sealing body at the end 54 on a closing element 70 which is formed as a band-shaped portion 55 having a plurality of notches 71.
  • the length of the individual closure elements 72, 73 may differ from each other.
  • the end elements 72, 73 have a substantially rectangular surface.
  • the end 54 may comprise at least one end element 70 from the group of flap-shaped extensions 74, the serrated notches 75, teardrop-shaped, wave-shaped shell elements 76.
  • the serrated notches 75 extend in a peak.
  • the teardrop-shaped or wave-shaped jacket elements 76 can also have a semicircular shape.
  • the terminating elements 70 according to each of the preceding embodiments can be arranged directly adjacent to one another or subsequently or at a distance from one another. End elements of any shape can be arranged side by side. At least a part of the end elements can be arranged in a scale shape one above the other.
  • a plurality of end elements 70 may be provided rotationally symmetrically on the band-shaped portion 55.
  • a closing element 70 is preferably attached at a distance of 1 mm to 5 mm.
  • the sealing body 5 may also be formed as a hollow body.
  • the mantle can be designed hemispherical or schellipsoid.
  • the sealing body may have a wall thickness which decreases between the base element 62 and the end 54. In the region of the first base element 62, the wall thickness is 0.5 mm to 15 mm, preferably 2 mm to 5 mm. Towards the end 54, the wall thickness of the sealing body 5 decreases and can be 0.01 mm to 1 mm, preferably 0.1 mm to 0.5 mm, at the end 54 and / or on the band-shaped section 55. The wall thickness depends on the material used and the geometry of the sealing body 5.
  • an elastic material such as silicone is used for the sealing body 5.
  • Other possible materials for the sealing body are thermoplastic elastomers (TPE), such as, for example, Santoprene® or further ethylene-propylene-diem rubber (EPDM) or fine polyethylenes (HDPE).
  • TPE thermoplastic elastomers
  • EPDM ethylene-propylene-diem rubber
  • HDPE fine polyethylenes
  • the materials have the advantage that they can be designed particularly thin-walled and are very elastic.
  • a material can be used, which still has a high mechanical strength even at low wall thicknesses. Due to the decreasing wall thickness of the sealing body towards the contact area, the elasticity of the sealing body is increased, whereby on the one hand improves the gas-tight seal and on the other hand, the flow of sanitary liquid is promoted by displacement of the sealing body. With large volumes of sanitary liquid, a discharge cross section can thus be achieved which corresponds approximately to the cross section of the tubular outflow. This is particularly advantageous in a so-called hybrid urinal applicable, which is operated in general as a waterless urinal, but in addition, for example, rinsed periodically with water via time-controlled water rinse. Even in applications in sinks or sinks or shower or bathtubs, it is advantageous if a large amount of sanitary liquid can drain. The small wall thickness of the sealing body at the end favors a gas-tight concern to the drain.
  • the jacket 52 has on its outer surface 53 at least one, in particular a plurality of directed in the direction of the end 54 inlet elements 60, which are formed as groove-shaped indentations 58.
  • the channel-shaped indentations may have a U-shaped cross section.
  • the channel-shaped recesses 58 may also be formed as notches. In particular, these notches may have a V-shaped cross-section.
  • the channel-shaped indentations 58 can initially extend on the sealing body 5 in the radial direction from the base element 62 to the end 54 or to the band-shaped section 55. According to the present exemplary embodiment, the channel-shaped indentations terminate upstream of the band-shaped section 55.
  • the channel-shaped indentations can be arranged rotationally symmetrically on the outer surface 53 of the jacket 5 of the sealing body 5.
  • the channel-shaped indentations and elevations can be arranged on the sealing body 5.
  • the sealing body 5 is wavy in a sectional plane which is normal to the longitudinal axis 31.
  • the wall thickness in the region of the channel-shaped indentations or elevations may be the same as in the environment of the same. It It has been shown that between four and twelve indentations or elevations combine the sanitary liquid optimally and favor a rapid outflow.
