Definitions

  • the invention relates to a urinal with a bowl, which forms a urinal basin, which has an outlet opening in its base, and with an odor trap connected to the outlet opening.
  • the odor trap In conventional urinals, the shell of which is mostly designed for wall mounting, the odor trap is located directly below the urinal basin, so that it is difficult to access during assembly and maintenance work.
  • waterless urinals are increasingly being used instead of urinals with water rinsing, in which in some embodiments a barrier liquid that is specifically lighter than water remains in the odor trap.
  • these waterless odor traps must be replaced from time to time or at least serviced, for example by replacing the sealing liquid, or losses due to evaporation must be replaced. Since the odor trap should therefore be easily accessible, it has been inserted directly into the floor of the urinal basin.
  • this has the disadvantage that the lid of the odor trap, which is usually made of plastic, is visible in the urinal basin and forms an unsightly and difficult-to-clean joint with the ceramic of the urinal basin.
  • the object of the invention is therefore to create a urinal in which the odor trap is concealed and is nevertheless arranged to be maintenance-friendly.
  • the shell forms an essentially vertical wall which separates the urinal basin from a chamber located behind it, and in that the odor trap is arranged in this chamber and is accessible from above.
  • the outlet opening runs obliquely from the bottom of the urinal basin through the vertical wall into the chamber which receives the odor trap.
  • the odor trap is therefore invisible behind the vertical wall. Nevertheless, the odor trap is easily accessible for maintenance work. All that is required to access the odor trap is an upper cover for the chamber behind the urinal basin to be removed so that the odor trap can be reached from above.
  • the odor trap itself can thus be of conventional design with the aid of a key which engages in the cover in a bayonet-like manner and is pulled out upwards.
  • the vertical wall separating the urinal basin from the chamber receiving the odor trap is preferably approximately semi-cylindrical, so that it bulges convexly into the urinal basin.
  • the chamber which can be either open or closed on the back facing the building wall, thus has the shape of an approximately semi-cylindrical vertical shaft and is preferably closed both at the upper end and at the lower end by a removable cover, which not only gives access to the odor trap, but also the wall mounting of the urinal basin is facilitated.
  • the convex shape of the vertical wall also has the advantage that the urine stream hitting the wall is better distributed and urine splashing back is minimized. Furthermore, this shape of the vertical wall allows a largely undercut-free design of the shell as a whole, so that the shell can also be injection molded from plastic materials and easily removed from the mold.
  • the invention also has the advantage that a forced ventilation valve can be arranged on the odor trap, which is then hidden behind the vertical wall and is therefore not visible when the urinal is in use and does not come into contact with urine either. Due to the forced ventilation of the trap, a significant disadvantage of conventional waterless urinals is avoided, which is that at a negative pressure in the pipe system, the barrier fluid "is removed by suction. The forced ventilation of the consumption is thus reduced to sealing liquid, and the barrier liquid need only be correspondingly greater intervals to be checked and / or supplemented.
  • a fragrance can also be added to the sealing liquid in the odor trap, so that conventional fragrance stones in the urinal basin can be dispensed with. Since the chamber receiving the odor trap is closed at the top, the fragrance can essentially only escape through the drain opening or openings in the bottom of the urinal basin, so that the release of the fragrance can be controlled and metered in a desirable manner.
  • the arrangement of the odor trap in the largely closed chamber also minimizes evaporation losses in the sealing liquid and any odor.
  • a larger storage container and an automatic metering system for sealing liquid and / or fragrance can also be arranged in the chamber behind the urinal basin.
  • the maintenance intervals are further extended by the automatic metering of the liquid.
  • Fig. 1 is a front view of the urinal;
  • Fig. 2 is a side view of the urinais;
  • Figure 3 shows the urinal of Figures 1 and 2 in plan view.
  • FIG. 4 shows a vertical section through the urinal mounted on a building wall
  • FIG. 5 shows an enlarged section through an odor trap of the urinais
  • 6 shows the odor trap according to FIG. 5 in a top view
  • 7 shows a vertical section through the urinal, analogous to FIG. 4, in a state during the removal of a cover of the odor trap.
  • the urinal shown in FIGS. 1 to 4 has a shell 10 designed for wall mounting, which is preferably made in one piece from plastic by the injection molding process.
  • the shell 10 forms a vertical, convexly curved wall 12 and a urinal basin 14 projecting from the convex front side of this wall 12.
  • the upper and lower openings of the chamber 18 are closed by removable covers 22, 24. As can be seen in FIG.
  • FIG. 4 also shows a drain pipe 28 laid in the building wall 16, which is connected to the odor trap 20.
  • the odor trap 20 is detachably suspended in an intermediate floor 30 arranged horizontally in the chamber 18 and integrally connected to the wall 12.
  • a pot 30a which receives the odor trap 20, is integrally formed on the intermediate floor 30.
  • a rear wall 31 protrudes from the intermediate floor 30, which extends higher than the "beak" of the urinal basin 14 and which forms a closed trough with the intermediate floor 30 of the arched wall 12. If the drain pipe 28 is blocked, the urine does not flow down into the chamber 18 on the building wall 16, but overflows forward from the urinal basin.
  • FIG. 5 shows the odor trap 20 inserted in the pot 30a in an enlarged section.
  • the pot 30a forms "at the bottom a terminal 30b for the drain pipe 28.
  • the water trap 20 is composed of three sonic by ultra- dense with interconnected plastics parts, namely a cup-shaped overflow vessel 32, a inserted into the overflow vessel 32 cylindrical insert 34 and a to the overflow vessel 32 has a lid 36 which is in the form of a flat funnel and has an open lower end of an overflow tube 38 which rises from the bottom of the overflow vessel 32 and is flush with the connection 30b has a dividing wall 40 running vertically in the upper area and slightly inclined in the lower area, which ends with its lower edge at a distance above the bottom of the overflow vessel 32 and runs diametrically through the cylindrical insert 34.
  • the cover 36 is inserted with a circumferential collar to fit into the upper opening of the overflow vessel 32 and closes the overflow vessel in a liquid-tight manner.
  • the cover 36 is also in liquid-tight engagement with the upper region of the partition 40 via two parallel flanges 42.
  • the overflow vessel 32 is suspended in the intermediate base 30 with a flange running around the upper edge in such a way that the funnel-shaped cover 36 is flush with the top of the intermediate base 30.
  • the cover 36 has a central bore 44 which is surrounded by three openings 46 arranged at uniform angular intervals, of which only one can be seen in FIG. 5 (cf. FIG. 6).
  • the outlet opening 26 of the urinal basin 14 opens directly above the top of the lid 36.
  • a boundary wall 48 which is U-shaped in plan and which surrounds the openings 46 and is connected with its parallel legs to the vertical wall 12 of the bowl 10 is formed on the lid , Outside the boundary wall 48, a plug-in coupling 50 for a forced ventilation valve 51 is arranged on the cover 36.
  • the forced ventilation valve 51 is mounted on a removable base 52 which rests on the boundary wall 48.
  • the urine flows through the outlet opening 26 via the cover 36 and its openings 46 into the overflow vessel 32 and fills it up to the level of the overflow pipe 38.
  • the dividing wall 40 separates the overflow pipe 38 from a barrier volume which contains a barrier liquid F which is specifically lighter than the urine.
  • the meniscus between the barrier fluid F and the urine is shown in broken lines in FIG. 5 and is (because of the weight of the barrier fluid) somewhat lower than the upper end of the overflow pipe 38 and the level of the urine there.
  • the urine freshly flowing in through the openings 46 sinks downward through the sealing liquid, so that, according to the principle of communicating tubes, the level of the urine in the area of the overflow pipe 38 also increases and the urine flows into the overflow pipe 38 and then into the drain pipe 28. flows.
  • the forced ventilation valve 51 opens and the space of the overflow vessel above the overflow pipe 38 is ventilated. This prevents urine and barrier fluid from being sucked out of the overflow vessel.
  • sealing liquid can evaporate through the openings 46. However, this evaporation largely comes to a standstill when the chamber 18 above the odor trap 20 is saturated with sealing liquid vapor. Only very small amounts of barrier liquid, to which a fragrance is preferably added, can evaporate through the outlet opening 26.
  • a reservoir 54 with sealing liquid and / or liquid fragrance is suspended in chamber 18 in the example shown, from which the liquid is gradually added to cover 36 via a hose 56 and a metering valve 58 - is trickled.
  • the cover 36 is sealed on the intermediate floor 30, it can also be permitted that, if the metering valve 58 is opened too far, the level 60 of the barrier liquid rises above the cover 36, as indicated by dashed lines in FIG. In this case, however, the evaporation rate increases, so that the liquid level stabilizes. At the same time, the desirable effect occurs that a larger amount of fragrance reaches the urinal basin 14 via the outlet opening 26. In this case, the delimitation wall 48 prevents the barrier liquid from flowing off via the intermediate floor 30.
  • a key 62 (FIG. 7) which is suitably adapted to the shape of the openings 46 is then inserted into the openings 46 from above and locked in a bayonet-like manner by slight twisting, so that the cover 36 and thus the entire odor trap are upward let the pot pull out 30a.
  • only the cover 32 of the odor trap can be removed. be acceptable.
  • FIG. 7 illustrates how the odor trap 20 is removed upwards using the key 62 mentioned.
  • the key 62 has a joint 64 and a lever 66 at the upper end. If the odor trap has become stuck in the opening of the intermediate floor 30 due to contamination and is therefore difficult to loosen, the lever 66 can be supported on the upper edge of the vertical wall 12 of the shell 10, so that the odor trap is levered out with increased force leaves.
