Description

The The invention relates to an odor trap for general drainage devices.

These traps be in all domestic Areas, but also in hygienically even more sensitive environment like for example, hospitals and similar used.

Publications from research institutes dealing with hygiene issues and elimination resulting problems, especially in hospitals, but also in the private sector emphasize clearly that the odor trap is one of the biggest sources of infection that's it in those areas at all gives.

This results from the fact that the wastewater is open to these rooms and thus There is a latent risk of germ formation and infection.

Of Further, there is a use of the conventional odor traps increased Risk that in the sewage vermin, z. Cockroaches and cockroaches, wander through the odor trap.

There These disadvantages were known by the most varied Constructions tries to fix these disadvantages, however only sporadically succeeded.

So is from the OS 103 18 831 a backwater stopper known, in which a float is used to close the flow opening.

Another similar solution describes the utility model DE 203 08 922 which also uses a float.

From the EP 1 247 910 is an odor trap for a waterless urinal known. Here, the gas passage is stopped by means of a siphon.

The existing known disadvantages of the prior art, however not fully remedied by these means.

So All these known solutions have the Disadvantage on that they do not completely dehydration protection with reliable Stop odor and improve hygiene.

One Another disadvantage of these solutions according to the state The technique consists of noise in the siphon due to pressure fluctuations in the drainage system.

task the invention is to propose a solution which overcomes the aforementioned disadvantages of the prior art.

These The object is achieved by the solution described in claims 1 to 4.

The solution according to the invention is based on 1 and 2 shown, where 1 the odor trap according to the invention in the open and 2 shows the odor trap according to the invention in the closed state.

Of the inventive odor trap sets are composed of 2 basic assemblies.

The first assembly is formed from the siphon container 1 by means of a calming surface 2 Calmed water supply and integrated container ventilation 3 and a float housing 4 , This float housing 4 is so in the siphon container 1 arranged that one in this float housing 4 arranged float 6 in this case 4 up to a float stop 8th can swim up.

Another element of this assembly is the Sogregulierdüse 12 , which are in the drainage area of the siphon container 1 is arranged.

At the upper end of the siphon housing 1 is a conventional compression fitting 15 intended for integration into the process.

The second module forms the lifting valve 5 , with float arranged on it 6 , at the lower end of a bottom seal 14 is arranged for sealing the lower outlet opening of the closure. At the top of the lift valve 5 is a buoyancy bubble 9 arranged.

Another element of the second module is the condensate inlet 10 , which at the lower end of the lifting valve 5 arranged so that accumulating condensate 11 in the lifting valve 5 defined to lead is.

The seal of the float 6 with the siphon housing 1 in an empty state is by means of a bottom seal 14 , which is at the bottom of the float 6 is arranged, realized.

following the function of the odor trap according to the invention will be explained in more detail.

The inflow of the odor trap according to the invention is carried out from above and is attached by means of a commercial screw with flat gasket on the drain set (for washstands 1 1/4 "and rinse 1 1/2").

Underneath is the tank vent 3 for venting the interior of the siphon housing 1 arranged where by means of a hose or pipe section, the air can escape during filling to the outside.

The wastewater, which now in the siphon container 1 enters, is about a calming surface 2 passed, in the edge drain holes 13 to sit. These have the function of directing the water targeted to the container wall or in channels to the lower part of the lifting valve.

The even water distribution on the float 6 guarantees an exact function as well as a secure starting state of the system.

in this connection will also be a possible shock overflow of the entire lifting device counteracted.

The water, which is now under the float 6 causes a slight floating and the associated lifting of the bottom seal 14 , the water drains off the bottom valve.

Increases the water level due to larger flow rates in the siphon further, the following situation occurs:

This is also in the riser 5 Rising water located compresses the air therein in an air bubble arranged above 9 , This buoyancy causes the lift valve to raise 6 with bottom seal 14 and the drain device opens fully.

The flow rate of the sloping waste water in the container and the outflow velocity have a self-cleaning effect of the sealing surfaces of the bottom valve 14 result.

This is especially realized by the arrangement of the Sogregulierdüse 12 below the siphon outlet.

These has the task to ensure the operating state of the opening and him over to secure the entire emptying process.

With the help of the Sogregulierdüse 12 the so-called suction effect of the sequence is canceled with a back pressure.

It comes to the uniform emptying of existing wastewater.

The Emptying speed is the same in a normal odor trap identical.

The lowering of the water level causes a slow lowering of the lifting valve 5 with floating body 6 as well as the bottom seal 14 ,

Any residual water runs under the bottom seal 14 The odor trap is now emptied and tight.

By the lift tube 5 located rubber bubble 9 Suction and pressure fluctuations of the downstream drainage pipes are absorbed to prevent unnecessary movement of the floor seal.

In each drain line is a normal phenomenon to record a condensation. The at the lower end of the lift tube 5 attached condensate guide 10 does the job, located in the inside of the lift tube 5 forming condensate 11 to the bottom of the bottom seal 14 to lead and to keep the sealing surfaces moist and tight by means of a small water film. As a result, drying and leaking of the seal is avoided for a long time.

Of the Wastewater outlet of the odor trap according to the invention can be formed in a vertical or horizontal shape.

Also the embodiment of the invention Odor trap allows the installation of an odor trap integrated backflow flap, the before flooding the odor trap in backwater protect should.

• 1. er ist hygienisch akzeptabel, da kein Schmutzwasser zurück bleibt und kein Ungeziefer Leitungen durchwandern kann.
• 2. er ist frostsicher und damit auch im Außenbereich einsetzbar, beispielsweise für Dauercamping oder Boote sowie Dachentwässerung bei gemischter Kanalanbindung
• 3. er weist im Dichtungsbereich einen Austrocknungsschutz durch die integrierte Kondensatrückführungseinrichtung auf
• 4. es ist keine Geräuschbelästigungen durch Druck und Sogschwankung vorhanden, da in der Heberohrblase alle Druck und Sogschwankungen aufgefangen werden.

The functional principle of the odor trap according to the invention can be transferred to all types of odor trap. Floats and sealing elements can be used in a wide variety of shapes and materials and should be regarded as belonging to the inventive concept. The odor trap according to the invention has nothing in common with the system of a conventional odor trap - the advantages of the new odor trap are:

• 1. It is hygienically acceptable, since no dirty water remains behind and no vermin can walk through lines.
• 2. It is frost-proof and therefore also suitable for outdoor use, for example for permanent camping or boats and roof drainage with mixed duct connection
• 3. it has in the sealing area a drying protection by the integrated condensate recirculation device
• 4. There is no noise pollution due to pressure and suction fluctuation, because in the Lifting tube bladder all pressure and suction fluctuations are caught.

Farther There are no maintenance costs such as electricity or control technology as well as maintenance work.

One upgrade existing facilities in hospitals, Grocery stores or in the private living area is possible at no great cost.
