Definitions

  • the invention relates to a siphon for sanitary facilities, comprising an S-shaped tube formed from a number of pipe sections, sleeves and sealing elements, wherein at least one of the pipe pieces has a U-shaped form.
  • Outlets of sanitary facilities are known in different designs for different applications.
  • siphon As drains for sinks and sinks, for baths and shower trays, various spouts and toilets and even gullies has established itself over the years, the so-called siphon. To whom the invention of the siphon can be attributed is not clearly assignable.
  • the Englishman Cummings used a patented device on a water boiler to operate a lever system via a handle protruding from the seat plate, which opened and closed a slide above the waste pipe and the water inlet tap for the flushing. Even the Englishman John Gaillait 1782 is attributed to a precursor of the modern siphon.
  • Siphons serve to trap odors between drain inlet and sewer connection, whereby the principle of operation of a siphon based on a so-called water castle.
  • the water lock consists of a barrier fluid such. As water in a mostly U-shaped piece of pipe between the inlet opening and the outflow opening is kept and the drainage thereby airtight, so that no smell from the channel to which the outlet opening is connected, can penetrate into the room. When using the sanitary device new water is introduced as a barrier liquid in the siphon and thus exchanged the barrier liquid of the water castle.
  • Siphons are used in all domestic areas, but also in hygienically even more sensitive environments such as in hospitals and similar facilities. Even in otherwise sensitive areas that should be kept odorless and germ-free, such. As in pharmacies, pharmaceutical production and chemical laboratories, siphons are used as odor traps in processes.
  • the invention is therefore based on the object to provide a siphon of the type mentioned above, which closes odor-tight and / or germ-tight at partially and / or completely missing barrier liquid.
  • a guide sleeve with a float sealing element is mounted in such a way in the bend of the U-shaped piece of pipe that the float sealing element, the U-shaped piece of pipe at too low liquid level in the pipe section with the liquid or in the absence of liquid this alone hermetically seals.
  • the invention is based on the consideration that the siphon should be closed even if too low and / or completely missing barrier liquid so that no malodors can penetrate into the room. Furthermore, the function of the drain should not be affected, so that it can be used at any time, without causing overflow of the sanitary facility.
  • the closing and opening can be controlled by a kind of closure element, which closes depending on the Sperrierikeitsstand and automatically opens again in use.
  • a closure element should be arranged as possible floatable on the liquid and be regulated by the liquid level in the pipe section in their opening and closing behavior. This is achieved by such a flap is designed as a float sealing element and this is mounted in a guide sleeve on the bend of the U-shaped pipe section of the siphon.
  • the float sealing element at its lower end region on the inlet side facing a rounding, so that in The siphon introduced wastewater can thereby open the float-sealing element. Due to the sewage pressure acting on the rounding, the float sealing element is raised and pressed into its associated guide sleeve. Thus, the siphon is open and the wastewater can flow through unhindered.
  • the float-sealing element is expediently provided with a notch in the end region on the inlet side facing.
  • This notch has the advantage that when closed or partially closed float sealing element in the pipe section and suddenly occurring large amount of wastewater this wastewater can flow into the notch and presses by means of the buoyancy forces acting then the float-sealing element in its guide sleeve so that the siphon is fully opened ,
  • the notch is introduced in addition to the above rounding on the float sealing element.
  • the lower end of the float-sealing element In order to achieve the best possible airtight closure of the siphon in the complete absence of the barrier liquid, it is advantageous to produce the lower end of the float-sealing element with a contour corresponding to the inner tube. This prevents penetration of malodor, germs and vermin through the siphon into the room. Even with only partially existing barrier liquid, the float-sealing element with its thus formed lower end can still dip a small piece in the still existing barrier liquid, so that the siphon is hermetically sealed.
  • a guide rail is expediently attached to the float sealing element.
  • This guide rail engages in an integrally formed on the guide sleeve guide slot.
  • a removable closure is attached to the guide sleeve in such a way that the float-sealing element can be easily removed for maintenance without dismantling the whole siphon.
  • this closure is attached to the opposite end of the bend of the U-shaped blank end of the guide sleeve.
  • the closure may be a commercially available screw cap closure with seal or the like for sanitary purposes.
  • a connecting element is expediently mounted between the closure and the upper end of the float sealing element.
  • the connecting element is attached to the inside of the closure.
  • the float sealing element can be taken out of the guide sleeve in a simple manner by opening the closure.
  • One possible embodiment of the connector is as a thread and / or rope. The advantage of this embodiment is that the tensile forces can be transferred in a simple but effective manner when removing the float sealing element. Furthermore, a thread and / or rope in the use of the siphon does not hinder the float sealing element in its movement in the guide sleeve.
  • the connecting element can also be a helical spring with a spring constant adapted to the intended use.
  • the coil spring has the advantage to press the float sealing element with a predetermined pressure steadily with its lower end against the barrier liquid. This ensures that the float sealing element with partially missing barrier liquid with the remaining The rest of sealing liquid together closes the siphon airtight.
  • the coil spring ensures that the siphon is sealed by the float sealing element in the absence of sealing liquid. If wastewater is returned to the siphon, the float sealing element opens it and compresses the spiral spring in the guide sleeve.
  • the coil spring can also serve to dismantle the float sealing element by being attached at one end to the upper end of the float sealing element and at its opposite end to the closure.
  • the connecting element is the combination of spiral spring and thread and / or rope.
  • the coil spring is loosely inserted between the upper end of the float sealing element and the closure in the guide sleeve and exerts only compressive force and the thread and / or the rope is, as mentioned above, installed between the float sealing element and closure and exercises the Traction during removal from.
  • the coil spring is advantageously protected against overstretching during removal.
  • a siphon with float sealing element in sanitary facilities that require a duct connection.
  • this sink, sinks, bathtubs, shower trays, toilets, bidets and / or urinals should be mentioned, as they are largely installed in closed spaces. Especially in such closed rooms, such. As bathrooms, washrooms, toilet facilities and / or laboratories, you want to prevent bad odors through the sewer system and penetration of germs.
  • a siphon with float sealing element is a particularly good odor trap drains for sanitary facilities, especially with only partially and / or completely missing barrier liquid.
  • the float sealing element closes the siphon against germ and / or vermin intrusion from the sewer out into the room tight.
  • such a siphon with float sealing element is easy to install and / or easy to retrofit existing outlets. Furthermore, no maintenance costs, such. As electric power or complex control techniques to.
  • a conventional siphon is a trap used primarily in sewer connections.
  • the principle of operation of an S-shaped piece of pipe, the lower bend of which always remains filled with sealing water and thus prevents the escape of gases from the sewage system into the building, is found above all in sinks, toilets, sinks and drains.
  • the bottle odor trap is due to its small depth to the wall, mostly for aesthetic reasons, often used for designer bathrooms.
  • Another name for the trap is Traps, from English "trap", the trap, so smell trap.
  • B. in rainwater drains the damming height of 100 mm, in waste water drains with 50 mm, given.
  • a siphon 2 according to FIG. 1 comprises a plurality of pipe sections 4, 6, in which a pipe section 4 has a U-shaped form.
  • the sewer pipe section 6 has a 90 ° bend 8 for connection to an in-house sewer system, which is usually laid within the masonry
  • the bend 8 of the sewer pipe section 6 may vary in its angle depending on the duct connection and is commercially available in various forms.
  • a commercially available threaded sleeve 10 with a seal 12 is provided.
  • the sewer pipe section 6 is inserted with a slightly tapered end 14 about 2 cm to 3 cm to its circumferential outwardly shaped stopper 16 in the channel-facing end 18 of the U-shaped pipe section 4.
  • a screw thread 20 is attached, with which a sleeve ring 22 is screwed with sealing ring 12.
  • the threaded sleeve 10 is thus tight and sealed and the end 14 can not slip out of the channel-side end 18, since the sleeve ring 22 presses with its inner edge region 24 on the stop 16.
  • no screw thread 20 ' is attached to the inlet side end 26, but an outwardly formed circumferential stop in the manner of the stop 16 and the inlet side end 26 is of a kind attached to an outlet port of the sanitary device attached.
  • a guide sleeve 30 is mounted, in which a float-sealing element 32 is mounted.
  • the guide sleeve 30 is open at its opposite end 28 of the bend 34 and by a screw cap 36 with a sealing element 38 in conjunction with a screw thread 40 firmly closed.
  • a guide slot 42 is at the Inside the guide sleeve 30 is mounted and serves to receive a guide rail 44 which is integrally formed on the float sealing element 32.
  • the float sealing element 32 has formed the guide rail 44 over its entire length so that the float sealing element 32 can not rotate in the guide sleeve 30, but can only perform a movement in the longitudinal direction for opening and closing the siphon 2. Furthermore, at the lower end region 46 of the float sealing element 32 of the side 48 facing the inlet 48, a rounding 52 is formed. In addition to the rounding 52, a notch 54 is introduced on the side 48 facing the inlet 48. The rounding 52 and the notch 54 serve, controlled by the buoyancy forces of the waste water, to open the float-sealing element 32 with incoming wastewater. The combination of rounding 52 and especially the notch 54 safely open the float sealing element 32, even in the case of rapidly inflowing and large amounts of waste water, without any backflow of the wastewater occurring. Thus, there is a kind of quick-opening mechanism.
  • a lower end 56 of the float seal member 32 is made according to the contour of the inner tube of the U-shaped pipe section 4.
  • the float-sealing element 32 as in FIG. 3 shown, absent and / or slight remainder of a barrier liquid 58 the siphon air and / or odor-tight seal.
  • a thread 62 is mounted between its upper end 60 and the screw cap 36. At this thread 62, the float-sealing element 32 can be pulled to remove from the guide sleeve 30. Furthermore, a spiral spring 64 is inserted between the upper end 60 and the screw cap 36. This presses the float sealing element 32 at partially or completely missing barrier liquid 58 in the bend 28 of the U-shaped pipe section 4, so that the siphon 2 at any time, either with the still partially existing barrier liquid 58 together or alone, odor-tight.
  • the coil spring 64 reaches its maximum deflection in this state and pushes the float-sealing element 32 with its lower end 56 against the contour of the inner tube and thus the siphon is closed air and / or odor-tight. It can also be clearly seen that a sufficiently large portion of the guide rail 44 remains in the guide slot 42, so that the float sealing element 32 can not be rotated in the guide sleeve 30 when wastewater flows in.
  • FIG. 2 A filled with sufficiently high level of barrier liquid 58 siphon 2 is in FIG. 2 shown.
  • the float sealing element 32 is here completely pressed by the barrier liquid 58 in its guide sleeve 30 and thus the siphon 2 is opened and the odor trap now forms only the barrier liquid 58.
  • the coil spring is by the pressure, the barrier liquid 58 to the float sealing element 32 exercises, completely compressed in the remaining space between the upper end 60 and the screw 34. Also in this space is now also the folded thread 62nd
  • siphon 2 with corresponding float sealing element 32 is only one embodiment and may show other siphon shapes.
  • the siphon 2 made of different materials, such. B. made of plastics, copper, brass and / or other materials used for sanitary purposes and suitable materials.
