Definitions

  • the invention relates to an odor trap element or a pouring spout, in particular for waterless urinals, according to the preamble of patent claims 1 and 4.
  • Odor traps for waste water connections have been used for a long time.
  • the simplest form of an odor trap element is a household siphon.
  • U-shaped pipes that are usually used, this requires a lot of space.
  • rinsing with odorless fresh water is necessary because the water in the pipes serves as an odor trap. This is why household siphons are not suitable for various applications.
  • waterless urinals offer little space for an odor trap element and no flushing is provided.
  • Waterless urinals have several advantages. On the one hand, water and running water costs can be saved by using such urinals. On the other hand, no fresh water connection is required for their installation, so that their location can be chosen very flexibly. Due to the lack of fresh water flushing, systems of waterless urinals often have to deal with odor nuisance and, due to the longer standing time of the wastewater, with constipation due to deposits.
  • Membrane technologies are known on the one hand. They enable easy cleaning, but there is an inevitable odor nuisance when changing or if the membrane is damaged.
  • Systems which provide a barrier layer with a barrier liquid, in particular an oil layer, as an odor barrier. When cleaning the system, there is again an unpleasant smell.
  • Known odor trap elements are, for example, in the WO 2007/149379 A2 and the EP 1 335 076 A1 described.
  • the object of the invention is therefore to provide an odor trap element, in particular for waterless urinals, which requires little maintenance, in particular cleaning without odor nuisance should be made possible and maintenance at longer intervals should be sufficient to block or clog the drain to prevent.
  • the invention solves this problem by an odor trap element with the characterizing features of claim 1. Deposits can be avoided to the extent that mechanical cleaning, which may be associated with odor nuisance, is hardly necessary due to the structure according to the invention. Dry cleaning is sufficient for maintenance.
  • the overflow edge lies on a liquid level and that the end region of the wall on which the overflow edge is formed and the liquid level are at an angle ⁇ 'to each other between 30 ° and 55 °, in particular at an angle ⁇ ' between 35 ° and 50 ° .
  • the collecting container and the first pipe section together form a siphon. This means that if there is liquid in the collecting container and in the first pipe section, there is an odor barrier between the inflow opening and the second pipe section. If the odor trap element is therefore installed in a spout, there is an odor trap between the surroundings of the odor trap element and the waste water connection. This can be achieved by arranging the inflow opening above the outlet opening and arranging the overflow edge at a height between the inflow opening and the outlet opening. The first pipe section therefore runs from the bottom of the collecting container in the direction of the inflow opening, that is to say from the bottom up.
  • the overflow edge determines the maximum liquid level in the odor trap element.
  • the maximum liquid level can be easily determined by pouring liquid into the odor trap element.
  • the liquid level is in a horizontal plane. This level represents the Liquid level level. Liquid therefore runs evenly over the entire overflow edge during the transition from the first pipe section to the second pipe section.
  • the second pipe section runs from the direction of the inflow opening in the direction of the outflow opening, ie from top to bottom.
  • the apex of the angle ⁇ ' lies at the intersection between the liquid level and the end region of the wall at which the overflow edge is formed, that is to say at the overflow edge.
  • the liquid level plane runs parallel to the cross-sectional area of the inflow opening.
  • the odor trap element can be installed or sealed particularly easily in a spout.
  • the overflow edge then lies in a parallel plane to the cross-sectional area of the inflow opening.
  • the first tube section is at an angle ⁇ 'between 30 ° and 55 °, in particular at an angle ⁇ ' between 35 ° and 50 ° to the liquid level, over its entire length.
  • a further wall in particular the first pipe section and the collecting container, is provided between the collecting container and the first pipe section, on the end region of which delimits the outlet opening a flow edge is formed, which is arranged in particular on a parallel plane to the liquid level , and wherein the flow edge is straight or convex as seen from the collecting container.
  • Both the collecting container and the first pipe section are advantageously delimited by the further wall. This means that the first pipe section lies against the collecting container. This gives a particularly space-saving embodiment.
  • the further wall terminates with the flow edge at its lower end region, that is to say at the end region facing the bottom of the collecting container.
  • the flow edge also forms the upper end of the outlet opening.
  • the flow edge lies on a plane which is in particular arranged horizontally.
  • liquid therefore flows evenly over the entire length of the flow edge. This creates advantageous turbulence during operation, which prevents deposits from accumulating in the area of the outlet opening. Especially deposits are effectively reduced if the flow edge is convex as seen from the collecting container.
  • a particularly good flow pattern and consequently only a few deposits can be achieved by the end region of the further wall on which the flow edge is formed and a parallel to the liquid level plane through the flow edge to one another at an angle ⁇ 'of between 30 ° and 55 °, in particular at an angle ⁇ 'are between 35 ° and 50 °.
  • the object of the invention is further to provide a spout, in particular a waterless urinal, which requires little maintenance, in particular cleaning without odor nuisance should be made possible and maintenance at longer intervals should be sufficient to prevent the drain from being blocked.
  • the invention solves this problem by a spout with the characterizing features of claim 4. Deposits can be avoided by the structure according to the invention to such an extent that mechanical cleaning, which may be associated with an odor nuisance, is hardly necessary. Dry cleaning is sufficient for maintenance.
  • the spout To operate the spout, it is mounted on a wall and connected to a waste water connection. A fresh water connection is not required. Due to the fact that the inflow opening is arranged above the outlet opening and below the overflow edge, an odor trap is created according to the invention between the waste water connection and the area around the spout.
  • the first pipe section runs from bottom to top, the second pipe section from top to bottom. Due to the horizontally or horizontally arranged overflow edge, liquid can flow evenly over the entire overflow edge from the first pipe section to the second pipe section. Any deposits are entrained so that the urinal is not blocked.
  • the apex of the angle ⁇ is at the intersection of the vertical the end region of the wall delimited by the overflow edge, that is to say on the overflow edge.
  • the first pipe section is at an angle ⁇ between 35 ° and 60 °, in particular at an angle ⁇ between 40 ° and 55 °, to the vertical over its entire length.
  • a horizontal flow edge is formed which is straight or from the collecting container ( 10) is convex as seen.
  • Both the collecting container and the first pipe section are advantageously delimited by the further wall.
  • the first pipe section then lies against the collecting container.
  • the further wall ends at its lower end with the flow edge.
  • the flow edge also forms the upper end of the outlet opening.
  • the flow edge is arranged horizontally. In operation, liquid therefore flows evenly over the entire length of the flow edge. This creates advantageous turbulence during operation, which prevents deposits from accumulating in the area of the outlet opening. Deposits are particularly effectively reduced if the flow edge is convex as seen from the collecting container.
  • the flow pattern in the pouring spout can be improved by the end region of the further wall on which the flow edge is formed being at an angle ⁇ between 35 ° and 60 °, in particular at an angle ⁇ between 40 ° and 55 ° to the vertical.
  • a one-piece base body, in which the odor trap element is sealed, can be provided.
  • the base body can be designed such that it has a bowl-shaped area for collecting the waste water, which opens into a drain. An odor trap element can then be sealed into the drain so that the Odor trap element can be covered by the base body and is no longer visible when the spout is mounted on a wall.
  • the overflow edge is straight or convex as seen from the first pipe section. This can further reduce the formation of deposits that could lead to closure. If the overflow edge is convex, the spatial arrangement of the odor trap element is determined by the fact that the overflow edge lies in a horizontal plane that determines the liquid level.
  • the wall is plate-shaped and flat or convex as seen from the first tube section. Deposits in the first pipe section can thereby be reduced.
  • the length of the wall corresponds to its length in the direction of flow.
  • the width is the extent parallel to the wall and perpendicular to the length, i.e. the extent transverse to the flow. It is particularly advantageous if the height of the first pipe section is smaller than the height of the second pipe section, in particular in a ratio of at least 1: 1.25.
  • the second pipe section connects below the overflow edge and / or Incline .
  • Liquid that enters the second pipe section thus covers a free fall. This favors the breaking off of possible deposits.
  • Another aspect of the invention provides that the second pipe section runs at least partially in contact with the first pipe section, the two pipe sections in particular being parallel to one another. This means that the side of the wall facing the collecting container delimits the first pipe section and the side of the wall facing away from the collecting container delimits the second pipe section. This allows a particularly space-saving embodiment.
  • a particularly advantageous flow profile is achieved in the area of the second pipe section immediately following the overflow edge. If the wall is flat, the width of the first and second pipe sections is the same.
  • first and second pipe sections have a common outer body, the common outer body being divided by the wall and the wall separating the pipe section from one another. This can further reduce the space requirement.
  • the wall does not divide the common outer body over the entire length, but only up to the overflow edge.
  • the first and second pipe sections are connected above the overflow edge.
  • the common outer body is connected to the outlet opening through an opening and can be connected to a waste water connection via the drain opening.
  • the wall and the further wall run parallel to one another.
  • This arrangement of wall and further wall enables a particularly advantageous flow pattern to be achieved and the formation of deposits to be reduced. At the same time, this arrangement is particularly space-saving.
  • the volume of the collecting container is at least twice as large as the volume of the first pipe section and / or the second pipe section. This ensures that a large volume is available for holding the waste water and possibly the sealing liquid, while at the same time requiring little space. The flow can also be improved.
  • the collecting container is designed in such a way that in the bottom of the collecting container opposite the inflow opening Side wall of the collecting container, the outlet opening is arranged. This enables an improved flow through the odor trap element and reduces the formation of deposits.
  • the collecting container has a height m which corresponds to the distance between the bottom of the collecting container and the inflow opening and that the outlet opening from the bottom of the collecting container to a height k of 10% to 30% of the height m of the Collection container is sufficient, in particular up to a height k of 15% to 25% of the height m of the collection container.
  • This enables a particularly advantageous flow rate to be achieved, while at the same time a closure by deposits can be avoided even in the case of longer periods of non-use.
  • the height of the outlet opening can be determined by the distance between the bottom of the collecting container and the flow edge. The outlet opening is therefore vertical in the operating orientation.
  • the inner wall of the collecting container is rounded, in particular free of edges, or that at least in the area of the outlet opening the area of the inner wall of the collecting container and / or of the first pipe section opposite the flow edge is rounded, in particular free of edges. This can reduce the formation of deposits, especially in the area of the outlet opening. Closure due to deposits can thus be avoided.
  • the inflow opening has a larger cross-sectional area than the outflow opening. This enables a particularly advantageous flow pattern and an efficient flow to be achieved.
  • the pressure with the, e.g. wastewater caught by the pouring spout into the odor trap element is reduced. Because of this and through the smaller drain opening, the flow in the odor trap element is largely determined by the structure of the odor trap element. Deposits can be avoided particularly well.
  • waste water and a sealing liquid are arranged in the collecting container, the sealing liquid being immiscible with water and having a lower density than water, in particular floating on water.
  • the wastewater forms a barrier between the wastewater connection and the area around the spout.
  • the barrier liquid between the waste water in the odor trap element and the area around the spout also acts as an odor trap. This can prevent odors from wastewater in the collecting tank.
  • An oil layer for example, is suitable as the barrier liquid. Due to the construction according to the invention, hardly any sealing liquid is lost when used. Refilling sealing liquid is only extremely rarely necessary.

  • the odor trap element 1 is designed in such a way that deposits caused by waste water 14 in the odor trap element 1 are entrained when effluent water 14 is used. As a result, the frequency of the necessary cleaning of the odor trap element 1 is considerably reduced. Since mechanical cleaning is usually not necessary, there is no complete removal of the barrier liquid 15 and the associated odor nuisance. For regular maintenance of the odor trap element 1, it is only necessary to replenish the barrier liquid 15 that has been lost. In addition, if necessary, cleaning can be carried out using chemical cleaning agents which do not impair the function of the barrier liquid 15. This can be necessary, for example, if there is no use for a longer period of time.
  • the embodiment shown is also particularly advantageous because it is particularly space-saving and can therefore be easily installed in common urinals.
  • Fig. 4 shows an exemplary embodiment of a spout according to the invention.
  • the spout is designed as a urinal 4.
  • the spout is mounted on a wall 40.
  • the inflow opening 11 of an odor trap element 1 is connected to the drain 42 of the pouring spout or the odor trap element 1 is sealed into the drain 42.
  • the odor trap element 1 is oriented such that the overflow edge 22 lies in a horizontal plane.
  • the drain opening 31 of the odor trap element 1 is connected to a waste water connection 43. Since a direct connection of the odor trap element 1 to a waste water connection 43 may not be possible in some cases, the connection can also be made via a connecting pipe 44, as in the illustrated embodiment.
  • wastewater 14 which is collected by the spout, via the outlet 42 into the odor trap element 1 and on to the wastewater connection 43.
  • the odor trap element 1 corresponds to that in 1 - 3 shown odor trap element 1.
  • the urinal 4 is designed such that it has a one-piece base body 41 which completely covers the odor trap element 1.
