Description

The The invention relates to a siphon for sanitary facilities, one from a number of pipe sections, Muffs and sealing elements formed S-shaped tube, in which at least one of the pieces of pipe a U-shaped Form has.

Outflows from sanitary Facilities are available in different designs for different Applications known. As drains for washing and sinks, for bathing and shower trays, various spouts As well as toilets and even gullies has over the years the so-called siphon established. On whom the invention of the siphon to be led back can, is not clearly assignable. At least the Englishman has Cummings in 1775 a patented device was used on a water boiler, with him over a protruding from the seat plate handle a lever system which has a slide over the waste pipe and the Water inlet tap for the rinse opened and also closed again. Also the Englishman John Gaillait becomes 1782 attributed to a precursor of the modern siphon. Not to mention may be the patented in 1778, downwardly opening hinge valve, which with rinse water was cleaned. This invention is the Englishman and versatile inventor Joseph Bramah (1749-1814) attributed to the year 1797 about 6000 "odor-damping plants" produced first patent for "one not smelling seat "with The today known basic form of the siphon finally became the Frenchwoman Benoist was granted in Paris on 19 June 1823 and has been further developed ever since.

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, which is kept in a mostly U-shaped piece of pipe between the inlet opening and the outflow opening and thereby airtight closes the drain, so that no smell from the channel to which the outlet 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. Such a siphon according to the preamble of claim 1 is for example from the US 1,593,083 A known.

siphons be in all domestic Areas, but also in hygienically even more sensitive environments like for example in hospitals and similar Facilities used. Also in otherwise sensitive areas, should be kept odorless and germ-free, such. In Pharmacies, pharmaceutical production and chemical laboratories, come Siphons as odor traps in processes for use.

Not often used spouts and / or processes above sanitary Facilities with a built-in siphon as odor trap can dehydrate quickly. The barrier fluid, mostly water, the water castle in the siphon evaporated and thus the drain is no longer hermetically sealed and smells bad channel smell as well as germs can to enter the room. Furthermore, in the extreme case of use the conventional one traps an elevated one Risk that pests in the sewage, such. B. cockroaches and cockroaches, the odor trap, so the conventional Siphon, wander through with partial and / or complete dehydration can.

The Risk of dehydration of the siphon when not in use is included higher Room temperatures, especially in summer or in southern countries, are often given. Furthermore, at Drying out and / or prolonged Standing the barrier liquid also biological conversion and / or degradation processes occur, the moreover evil odors and release germs.

moreover there is also a risk of negative pressure formation in the duct system, especially in high-rise buildings such as B. at large Hotel facilities and / or hospitals as well as big ones Apartment blocks, so that the barrier liquid the water castle is sucked through this into the channel and thus the drain for smells, Germs and / or vermin are open to enter the room.

Of the Invention is therefore based on the object, a siphon of the above specify the type mentioned, the partially and / or completely missing barrier liquid odor-tight and / or germ-proof closes.

These The object is achieved according to the invention by in the bend of the U-shaped pipe section a guide sleeve with a float sealing element is mounted such that the float sealing element the U-shaped Pipe piece at too low fluid level in the pipe section with the liquid together or in the absence of fluid 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 Ver closing and opening can be controlled by a kind of closure element, which closes depending on Sperrflüssigkeitsstand and automatically opens again in use. In order to take this issue into account, such 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.

advantageous Embodiments of the invention are the subject of the dependent claims.

advantageously, has the float sealing element at its lower end on the the inlet side facing a rounding, so that in the Siphon introduced wastewater can thereby open the float sealing element. By the sewage pressure acting on the rounding becomes the float sealing element raised and in its associated Guide sleeve pressed. Consequently the siphon is open and the sewage can flow through unhindered.

ever according to the diameter of the siphon and the flow through the waste water volume It makes sense to use the float sealing element with a type of quick-release mechanism to provide. For this purpose, the float-sealing element is expediently with a notch in the end area on the inlet facing Side provided. This notch has the advantage that when closed or partially closed float sealing element in the pipe section and suddenly occurring large amount of waste water this wastewater can flow into the notch and then by means of the acting buoyancy forces the float sealing element presses into its guide sleeve so that the siphon is fully open. The notch is additional introduced to the above rounding on the float sealing element.

Around one possible airtight closure of the siphon in the complete absence of the barrier liquid To reach it, it is beneficial to the lower end of the float sealing element to produce a contour corresponding to the inner tube. Thereby becomes a penetration of evil Odor, germs and vermin prevented by the siphon into the room. Even with only partially existing barrier liquid, the float sealing element with his so formed lower end still a little piece in the immerse remaining barrier liquid, so that the siphon is hermetically sealed.

In order to the float sealing element is not affected by the sewage flow in the Guide sleeve twisted can and / or otherwise slip, is expediently on the float sealing element a guide rail appropriate. This guide rail engages in an integrally formed on the guide sleeve guide slot one. As a result, a constant alignment of the float sealing element for Wastewater flow out and in addition given a good and consistent motion control in the guide sleeve. In addition, this system with guide rail and associated guide slot the correct insertion of the float sealing element in the Guide sleeve in the Installation given.

advantageously, is on the guide sleeve removable closure attached in the manner that the float sealing element in a simple way for Maintenance work can be expanded without the whole siphon too disassemble. Conveniently, this closure is at the opposite end of the bend of the U-shaped blank the guide sleeve attached. The closure can be a for sanitary Equipment commercial screw cap with gasket or similar be.

For the purpose of easy disassembly and access to the float sealing element, z. B. for cleaning and / or maintenance purposes, is expediently between the closure and the upper end of the float sealing element Connecting element attached. The connecting element is at the Fixed inside of the closure. This allows the float sealing element when opened the closure in a simple manner using the connector the guide sleeve out be taken. A possible Embodiment of the connector is as a thread and / or Rope. Advantage of this embodiment is that the tensile forces at Removal of the float sealing element in a simple but effective Transmit manner can be. Furthermore hinders a thread and / or rope in use the siphon the float sealing element not in its movement in the guide sleeve.

However, 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. Thus, it is ensured that the float sealing element with partially missing barrier liquid with the remaining remainder of sealing liquid together closes the siphon airtight. In addition, the coil spring ensures that the siphon is closed by the float sealing element in the absence of sealing liquid is. If wastewater is returned to the siphon, the float sealing element opens it and compresses the spiral spring in the guide sleeve. In addition, 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.

A more possible Form of the connecting element is the combination of spiral spring and Thread and / or rope. The coil spring loosely between the upper end of the float sealing element and the closure in the Guide sleeve inserted and practice only compressive force and the thread and / or the rope is how mentioned in the foregoing, between float sealing element and Lock installed and exercises the tensile force during removal from. In this combination is advantageously the spiral spring opposite an overstretching protected during removal.

Advantageous is the use of a siphon with float sealing element at sanitary Devices that require a duct connection. In particular, this is Washbasin, sink, bathtubs, Shower trays, toilets, bidets and / or urinals to name as these largely in closed rooms are attached. Especially in such closed rooms, as z. B. Bathrooms, Washrooms, Toilet facilities and / or laboratories you are evil odors through the sewerage and prevent penetration of germs.

The particular advantages of the invention are that a siphon with float sealing element a particularly good odor trap of drains for sanitary facilities, especially with only partially and / or completely missing barrier liquid, is. In addition, closes the float sealing element the siphon also against germ and / or plague intrusion from the sewerage into the room tightly off. Furthermore Such a siphon with float sealing element is easy to install and / or existing drains easy to retrofit. Furthermore, no maintenance costs, such. B. electrical Electricity or complex control techniques.

One embodiment The invention will be explained in more detail with reference to a drawing. Show:

1 a siphon on average,

2 the siphon with sufficiently high barrier fluid level in the section, and

3 the siphon with closed float sealing element in section.

Same Parts are provided with the same reference numerals in all figures.

at a conventional one Siphon is one used mainly in sewer connections Trap. The operating principle of an S-shaped pipe section whose lower bend always remains filled with sealing water and thus the outlet of gases from the sewage system into the building prevented finds itself especially with sinks, toilets, sinks and drains. There are basically four Types: the tube odor trap, the bottle odor trap, the diving wall odor trap and the bell odor trap. The bottle odor trap will due to its small depth to the wall, mostly of optical Establish, like for designer bathrooms used. Another name for the trap is Traps, from English "trap", the trap, so smell trap Dimensioning and, above all, professional training the accumulation heights and the sealing water level, such as B. in rainwater drains is the damming height with 100 mm, with waste water drains with 50 mm, given.

A siphon 2 according to 1 comprises a plurality of pipe pieces 4 . 6 in which a piece of pipe 4 has a U-shaped form. The sewer pipe section 6 has a 90 ° bend 8th For connection to an in-house sewer system, which is usually installed inside the masonry. The bend 8th of the sewer pipe section 6 can vary in its angle depending on the duct connection and is commercially available in various forms.

For connecting the individual pipe sections 4 . 6 is a commercially available screw socket 10 with a seal 12 intended. The sewer pipe section 6 comes with a slightly rejuvenated ending 14 Approximately 2 cm to 3 cm to its circumferential outward shaped stop 16 in the end facing the channel 18 of the U-shaped pipe section 4 inserted. At the canal end 18 is a screw thread 20 attached, with a sleeve ring 22 with sealing ring 12 is screwed. The screw sleeve 10 is thus tight and sealed and the end 14 can not leave the channel end 18 slip out, as the sleeve ring 22 with its inner edge area 24 on the stop 16 suppressed.

A connection to a sanitary device, such as a sink, takes place in principle according to the above-mentioned socket construction, by a straight extension pipe piece by means of a screw sleeve 10 ' at the inlet end 26 of the U-shaped pipe section 4 with the help of a screw thread 20 ' is screwed on. In the event that no Extension pipe is needed is at the inlet end 26 no screw thread 20 ' attached, but an outwardly shaped circumferential stop in the manner of the stop 16 and the inlet end 26 is attached with a kind of flange sleeve to an outflow opening of the sanitary facility.

At a bend 28 of the U-shaped pipe section 4 is a guide sleeve 30 attached, in which a float sealing element 32 is stored. The guide sleeve 30 is at her bend 28 opposite end 34 open and through a screw cap 36 with a sealing element 38 in interaction with a screw thread 40 firmly lockable. A guide slot 42 is on the inside of the guide sleeve 30 attached and serves to receive a guide rail 44 attached to the float sealing element 32 is formed.

The float sealing element 32 has the guide rail 44 formed over its entire length, so that the float sealing element 32 not in the guide sleeve 30 can twist, but only a longitudinal movement to open and close the siphon 2 can perform. Furthermore, at the lower end 46 of the float sealing element 32 to the inlet 48 facing side 50 a rounding off 52 formed. In addition to the rounding off 52 is on the to the inlet 48 facing side 50 a notch 54 brought in. The rounding off 52 and the notch 54 serve, controlled by the buoyancy forces of the wastewater, to the opening of the float sealing element 32 with inflowing wastewater. The combination of rounding 52 and especially the notch 54 open the float sealing element 32 Even with fast inflowing and large amounts of wastewater safely, without any backflow of wastewater occurs. Thus, there is a kind of quick-opening mechanism.

A lower end 56 of the float sealing element 32 is according to the contour of the inner tube of the U-shaped pipe section 4 manufactured. This allows the float sealing element 32 , as in 3 shown, with missing and / or slight remainder of a barrier liquid 58 Close the siphon in an air-tight and / or odor-proof way.

To remove the float sealing element 32 ease of maintenance is between its upper end 60 and the screw cap 36 a thread 62 appropriate. At this thread 62 can the float sealing element 32 for removal from the guide sleeve 30 to be pulled. Furthermore, between the upper end 60 and the screw cap 36 a coil spring 64 plugged in. This presses the float sealing element 32 with partially or completely missing barrier liquid 58 in the bend 28 of the U-shaped pipe section 4 into it, so that the siphon 2 at any time, either with the still partially existing barrier fluid 58 together or alone, odor-tight.

One except for a small amount of barrier fluid 58 dried siphon 2 with closed float sealing element 32 is in 3 shown. The spiral spring 64 reached in this state, their maximum deflection 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. Good to see is that a sufficiently large portion of the guide rail 44 in the guide slot 42 remains so that the float sealing element 32 not with inflowing wastewater in the guide sleeve 30 can be twisted.

One with a sufficiently high level of barrier fluid 58 filled siphon 2 is in 2 shown. The float sealing element 32 Here is completely from the barrier fluid 58 in his guide sleeve 30 pressed and thus is the siphon 2 opened and the odor trap now forms only the barrier liquid 58 , The spiral spring is due to the pressure that the barrier fluid 58 on the float sealing element 32 exercises completely in the remaining space between the upper end 60 and the screw cap 34 bawled. Also in this open space is now also the folded thread 62 ,

The in the 1 to 3 shown siphon 2 with corresponding float sealing element 32 is only one embodiment and may show other siphon shapes. Likewise, 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.
