Definitions

  • the present invention relates to a suction siphon for a flush-mounted installation according to the preamble of claim 1, which is particularly useful for toilet urinals and the like ..
  • Siphonic siphons for drainage installations are mainly known for urinal drainage.
  • the EP 1 416 098 A1 a Absaugsiphon ago, which has a flow channel with a circular cross section for hydraulic optimization and also consists of two shell-shaped halves, so that it is relatively inexpensive to produce.
  • the purge volume required with this siphon is in the range of 0.8 to 1.5 liters, which is still a relatively high value.
  • the object of the present invention is thus to provide a suction siphon, which manages with less than 0.8 liters of flushing and in which nevertheless a sufficient suction effect is provided.
  • the should inventive Absaugsiphon be compact designed for flush-mounted installations and inexpensive to produce.
  • the inventors have recognized that the required flushing amount can be reduced by a substantially laminar flow is achieved by generously dimensioning the radius of the winding section serving as an odor trap, the less rinse water to achieve the suction effect required.
  • the turn portion extends substantially around a turn point, the turn portion having a flow passage outside and a flow passage inside with respect to the turn point.
  • the distance of the flow channel inside the Windungsabitess to Windungstician should then according to the invention at least 10% of the distance between the flow channel outside and flow channel inside in the winding section.
  • This ratio is at least 15%, and more preferably at least 25%.
  • larger ratios could be used, but this would then be at the expense of the compactness of the Absaugsiphons, so that such Absaugsiphons could be used only poorly in flush-mounted installations due to limited in some types of urine installation space.
  • This sudden reversal of the flow by 180 ° creates a highly turbulent flow, which requires the relatively high flushing water requirement.
  • the siphoning siphon of DE 2 447 695 A1 Although has a serving as an odor trap winding portion in which the winding point does not extend within the flow channel inside, but here is a ratio in relation to the distance between the flow channel outside and flow channel inside of at most 5% before, which is not sufficient to such a laminar To achieve flow, which leads to a significant saving of rinse water.
  • the Absaugsiphon invention for a drain installation, in particular a toilet urinal or the like. Comprising an inlet and an outlet port and a preferably arranged in a housing flow channel for liquid to be derived, the flow channel input to the inlet port and the flow channel exit are connected to the outlet port the flow channel is at least partially wound around the inlet connection and the turn of the flow channel is at least partially formed as a helical winding formed in a plane, wherein at least one winding section of the flow channel serves as an odor trap, wherein the winding section substantially around a Windungsddling around and wherein the winding section has, with respect to the winding point, a flow channel outside and a flow channel inside, wherein inlet connection and / or outlet at End is preferably formed as a nozzle, and is characterized in that the distance of the flow channel inside the Windungsabêts to Windungsddling is at least 10% of the distance between the flow channel outside and flow channel inside in the winding section, preferably at least 15%,
  • the flow duct in a preferred embodiment, provision is made for the flow duct to have a first rectilinear flow duct section in relation to the flow direction upstream of the turn section formed as an odor trap, which has a gradient that is different from the vertical with respect to the installation position of the suction siphon and / or that follows as an odor trap trained Windungsabêt in the flow direction is another turn section and then a second rectilinear flow channel section, which has a different from the vertical difference in relation to the mounting position of Absaugsiphons.
  • the flow channel inlet and the flow channel outlet advantageously run parallel to one another.
  • the flow channel has at least two rectilinear portions which are not parallel and not perpendicular to each other. This also makes the Absaugsiphon very compact, because the inclined to each other extending sections take up less space.
  • the compactness can be further increased if the flow channel has at least one flattening on at least one lateral boundary of the suction siphon with respect to the tubular course of the flow channel.
  • This lateral boundary may be provided on any side of the suction siphon, but preferably on the sides, which extend vertically with respect to the installation position tangential to the helical course. If an inclination of the winding portion of the Absaugsiphons is provided, then flattening can be provided on both sides, so that in contrast to a unilateral flattening results in a lower fluidic effect, since the cross-section must be flattened about half as strong to the required dimensions of, for example, currently to comply with the usual 100 mm.
  • the plane of the spiral-shaped turn of the flow channel is arranged in an area + 45 ° to -45 ° inclined to the vertical, preferably in a range + 20 ° to -20 ° inclined to the vertical, in particular vertically aligned.
  • the flow channel is at least partially tubular and advantageously at least partially, preferably completely has a hexagonal, octagonal and decagonal cross section, on which in particular a capacitive sensor is arranged.
  • this design is favorable in terms of flow, but on the other hand makes it possible to easily integrate sensors for actuation. While in round pipe sections either the sensor would have to be bent or formed on the pipe material thickening is to attach a planar sensor, this is no longer necessary. As a result, the production is cheaper and the sensor performance is better, since by such material thickening in capacitive sensors, one plate is a sensor plate and the other plate is formed by the flowing behind the pipe water, the detection accuracy of the sensor is reduced.
  • the flow channel is formed at least in the region of the turn, with the exception of possibly provided flattenings having a constant cross section.
  • the flow channel has a portion which extends at an angle, in particular a right angle from the plane of the winding of the tortuous portion of the flow channel extends with a smaller cross section over a first length into the outlet port, which has a larger cross section. It is expedient if this section is the flow channel exit, because the Absaugsiphon can then be kept very compact, but can also be provided that this section is arranged between the flow channel exit and the tortuous area. It is preferably provided that the plane of the winding of the tortuous region extends vertically and the flow channel exit is arranged at a right angle thereto.
  • the outlet connection is therefore formed with a larger cross section, because it is the connection to standard sanitary pipes.
  • the flow channel has a smaller cross section in order to reduce the flushing water requirement.
  • the outlet connection preferably encompasses the flow channel at a distance along a second length, thereby forming a free space around the flow channel communicates with the outlet port.
  • the plane of the winding of the tortuous region extends vertically and the flow channel exit is arranged at a right angle thereto.
  • the first length is at least 10 mm, preferably at least 20 mm, in particular at least 30 mm. Then whirlpools are particularly well prevented. It is also advantageous if the first length is equal to the second length, if both alternatives are realized at the same time, because then a very large annular space is available. Furthermore, it is advantageous if the section extends perpendicular to the helically wound region of the flow channel. Through all these measures, the flow can be further influenced advantageous, which additionally reduces the Spülwasser pocket.
  • the cross section of the flow channel is at least 10%, preferably at least 20%, in particular at least 30% smaller than the cross section of the outlet connection.
  • the cross section of the flow channel in the transition between the flow channel and the outlet connection essentially corresponds to the cross section of the tortuous region of the flow channel.
  • Fig. 1 shows a perspective top view
  • Fig. 2 a top view from the front
  • Fig. 3 a side sectional view
  • the suction siphon 1 has an inlet connection 2 with a lamellae receptacle 2 a for a urinal (not shown) and an outlet connection 3 as well as a flow channel 4.
  • the Absaugsiphon 1 a housing 5, which is formed from two shell-shaped elements 6, 7, which consist of an injection-molded plastic and, for example, welded or glued together.
  • the flow channel 4 has a first turn section 8, which serves as an odor trap 9, and the flow channel 4 winds helically around the entry connection, wherein beside the first turn section 8 a second turn section 10 and a third turn section 11 are provided and additionally in front of the first turn section 8, a first rectilinear flow channel section 12, between the first coil section 8 and the second coil section 10, a second rectilinear flow channel section 13 and between the second coil section 10 and the third coil section 11, a third rectilinear flow channel section 14. It can be seen that the first rectilinear flow channel section 12 and the third rectilinear flow channel section 14 parallel to each other. The second rectilinear flow channel section 13 is inclined thereto, i. neither parallel nor vertical.
  • the flow channel 4 as best of Fig. 3 to recognize an octagonal cross section.
  • a laminar flow is favored, wherein alternatively also hexagonal or decagonal cross-sections can be provided, and in addition a capacitive sensor can be particularly easily provided on the Install flow channel, which is provided for example as a simple metal plate on the back of the housing 5 and for automatically detecting a use event and the subsequent triggering of a purge.
  • the hexagonal, octagonal or decagonal cross-section offers better stability compared to approximately circular cross-sections, the sensor is easier to attach to those in this Cross sections present straight wall sections 15 and has a better performance.
  • the first winding section 8 of the flow channel 4 which forms the odor trap 9, there is a uniform bending radius, which refers to the winding point 16.
  • the first winding section has a flow channel inside 17 and opposite a flow channel outside 18.
  • the distance between Windungstician 16 and flow channel inner side 17 (which is assumed to measure of the flow on the inner surface of the flow channel inner side 17) is relative to the light shaft between flow channel inner side 17 and flow channel outer side 18 about 27%, This creates a very laminar flow in the first turn section when operating the flush, whereby only a small amount of rinse water is needed.
  • the flow channel 4 In addition to the helically wound around the inlet port 2 around area 19 of the flow channel 4, the flow channel 4 also has a perpendicular thereto extending flow channel region 20, which forms the flow channel exit 20.
  • This second flow channel region 20 extends over a length L within the outlet connection 3 and has a smaller cross section with respect to the cross section of the outlet connection 3.
  • the stabilization in the flow is further assisted by the fact that the outlet connection 3 surrounds the second flow channel region 20 at a distance, so that a free space 21 is formed between the second flow channel region 20 and the outlet connection 3, which communicates with the outlet connection 3. This effectively prevents the entry of bioslurry into the flow channel (4, 20).
  • the first length L is equal to the second length.
  • the length L of the second flow channel region 20 is approximately 170% of the difference between the cross sections of the outlet port 3 and the second flow channel region 20 and is greater than 30 mm.
  • the cross section of the second flow channel region 20 is approximately 35% smaller than the cross section of the outlet port 3.
  • the present invention provides a siphoning siphon 1, which requires less than 0.8 liters of flushing, in particular at most 0.5 liters of flushing and still provides a sufficient suction effect is provided.
  • the Absaugsiphons invention is compact and thus suitable for all types of urine in flush-mounted installations and also inexpensive to produce.
