Definitions

  • the invention relates to an odor trap for a Sanitärwasserabhne according to the preamble of claim 1.
  • EP 1 076 739 A1 is an odor trap for a urinal known.
  • This includes a replaceable pot for insertion into the urinal, a lid for covering the pot, the lid having an opening for introducing urine into the pot.
  • a baffle to retain channel odor from drain lines.
  • the pot for collecting urine floats an odor barrier, which closes the opening in the lid.
  • a disadvantage of the described odor trap is that the float is pressed by its buoyancy in the urine to the lid. For this purpose, a certain amount of urine must be steadily retained, which ensures the buoyancy. Prolonged inactivity causes urine to evaporate, causing the float to sink and release the opening.
  • the check valve has an inlet section in the form of a self-supporting trough-shaped section. Connected to the inlet portion is an outlet portion of a flexible, resilient material.
  • the outlet section has a flat, flexible, compliant strip with a high inherent degree of flexibility.
  • the outlet portion further includes a separate component from the strip which provides a complementary surface against which the lower end of the flexible strip is capable of sealing.
  • this check valve has the disadvantage that the discharge amount of the used water is limited by the long and narrow outlet section. There is also the risk that solids will stick to or in the elongated outlet section and thus a gas-tight closure of the valve prevent.
  • the present invention is therefore based on the object to provide an improved odor trap for a Sanitärwasserabpound, which is simple and inexpensive, reliable and has a compact height.
  • the sanitary tap trap particularly for a urinal, includes an inlet having at least one opening to a drain, short drain, for sanitary water and a tubular drain which connects to the inlet with an upper end, the tubular drain enclosing the inlet.
  • the sanitary water flows through the drain and exits from a lower end of the drain.
  • a umbrella-shaped sealing body is arranged and attached to the inlet side.
  • the sealing body is at least partially disposed in the tubular drain, wherein the sealing body fills the cross section of the drain and circumferentially in a contact area at the tubular drain in wesenttichen and forms inflow of urine or rinse water wrinkles through which the liquid expires. Due to the concern or almost concern of the sealing body on the inner wall of the drain is prevented in a first state that unpleasant odors from a sewer system can pass the trap.
  • the sealing body closes by its shape the entire cross section of the tubular drain.
  • the sealing body forms by its shape, which is adapted to the inner cross section of the drain, a drain cross section spanning sealing zone.
  • the sealing zone can be sealed by an interfacial tension in the contact area with the drain.
  • Adhesion forces between the sealing body, the inner wall and the sanitary residual water can also support a gas-tight seal of the odor trap.
  • the sealing zone is not dependent on a liquid film. Since drying out of the sealing zone does not have to be prevented or delayed, a short sealing zone and thus a more compact construction of the odor trap are possible.
  • the sealing body When entering sanitary water, e.g. Urine, in the odor trap from the inlet side, in a second state, the sealing body is displaced or radially deformed by the sanitary water in such a way that a drainage cross-section is created for the sanitary water and the sanitary water can flow out through the odor trap.
  • the deformability of the sealing body allows that even very small amounts of sanitary water or even individual drops can pass through the trap.
  • the release of the outflow takes place in a larger or smaller area.
  • the sealing body is only just so much displaced by the effluent sanitary water that no sewerage odors can pass the trap. Since the size of the discharge cross-section released by the sealing body is regulated by the sanitary water itself, a simple, reliable and cost-effective construction of the odor trap is possible.
  • the low force, which is exerted by the sanitary water pressure on the sealing body, causes a sufficiently large change in the free flow cross-section.
  • the sealing body with the peripheral contact region is dense or gap-forming linear or band-shaped on the inner wall or at the lower end of the drain and forms the sealing zone.
  • a line-shaped contact area of the sealing body is sufficient to form a gastight odor trap. Due to the low contact area, gluing of the sealing body with the drain and thus the probability of failure are additionally reduced. A wider contact area results in an even better and more reliable seal, which can still seal gas-tight, for example, even in the case of slight contamination of the contact area.
  • the sealing body has cuts in the contact region or parts in the contact region of the sealing body are in the shape of a scale one above the other.
  • a circumferential rib is arranged on the sealing body.
  • the rib increases the dimensional stability of the sealing body, whereby it rests evenly on the sealing zone of the tubular drain.
  • the sealing body has a shape which is adapted to the inner contour or to the lower edge of the drain.
  • the sealing body may have the shape of a ball, a cap, a cone, an ellipsoid or a drop.
  • the sealing body may consist of a half-body, the previously described body, where it may also be formed as a hollow body.
  • the shape of the sealing body should connect to the tubular drain. For example, in a circular cross-section of the drain used previously described forms become. For the reliable drainage of sanitary water, 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.
  • 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.
  • 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 has one of the previously described forms and ends preferably at the point with the largest circumference of the sealing body with a circumferential edge, which forms a flat surface on the underside of the half-body.
  • a sealing body lying in the tubular drainage is inflated by the pressurized sewage odors, similar to a parachute, and forced against the tubular drainage, whereby an additional sealing effect against sewerage gases is achieved.
  • the sealing body is made at least in the contact region of an elastic and / or thin-walled material and / or the drain comprises at least in the region of the lower end of an elastic element.
  • elastic, thin-walled materials a rich concern of the sealing body is made possible to the tubular drain. This results in a gas-tight closure of the drain.
  • an elastic, thin-walled material can easily be displaced radially outward by outflowing sanitary water.
  • sanitary water e.g.
  • made of elastic, thin-walled material sealing body is particularly strong folded together by sanitary water and thus represents a very low flow resistance in the tubular drain. The sealing body obstructs the water flow hardly.
  • the sealing body is made of a urine and detergent-resistant plastic, in particular of silicone and / or of a thermoplastic elastomer (TPE), such as Santoprene ® Exxon Mobil, or ethylene-propylene-diem rubber (EPDM) and / or fine polyethylenes (HDPE).
  • TPE thermoplastic elastomer
  • EPDM ethylene-propylene-diem rubber
  • HDPE fine polyethylenes
  • Silicone has the advantage that it can be made very thin-walled and is very elastic. Furthermore, silicone is very resistant to mechanical stress. Silicone, however, can respond to common cleaning and disinfecting agents by rolling and / or swelling, whereas from an ethylene-propylene-Diem rubber (EPDM) and / or of fine polyethylenes (HDPE) existing sealing body better resistance to cleaning and disinfecting agents having.
  • EPDM ethylene-propylene-Diem rubber
  • HDPE fine polyethylenes
  • the material of the sealing body must be as resistant to cleaning agents used in the sanitary area, otherwise it may lead to the dissolution or deformation of the sealing body. As a result, it no longer connects to the tubular drain in a gas-tight manner and must be repaired or replaced. It has been shown in practice that advice on cleaning or the prohibition of certain cleaning agents are often disregarded.
  • the axial length of the drain is equal to or less than the diameter of the drain.
  • the axial length of the drain is preferably 10mm to 50mm, more preferably 20mm to 35mm, and the diameter of the drain is preferably 10mm to 50mm, more preferably 20mm to 35mm. 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 Gerüchsver Why can be used in sink, creating less space below the sink for the drain.
  • the diameter of the sealing body is greater than or equal to the diameter of the drain. Due to the at least equal diameter of the sealing body opposite the drain, a gastight closure of the odor trap against sewerage odors is made possible even in the dry state. If the sealing body protrudes from the lower end or the lower edge of the drain, a sealing body is used which has a larger diameter than the tubular drain and thus covers the entire tubular drain.
  • the sealing body is axially connected by a first coupling element with the inlet.
  • a first coupling element By an axial elastic connection, an axial movement of the sealing body can occur during the inflow of sanitary water into the odor trap, as a result of which impurities in the sealing zone are mechanically removed.
