The known waterless urinals have the disadvantage that in use deposits by sparingly soluble substances, for example

Uric acid compounds and phosphates, which can clog the process. Also, the problem arises that objects such as cigarette remains, chewing gum and broken glass are thrown into the urinal, can be deposited there and lead to a blockage of the urinals. Such a blockage usually can not be remedied without dismantling at least part of the drain. This entails the danger that, when replacing the siphons, blast gases which have formed during operation of the toilets due to organic degradation products and accumulate in the region of the process can escape.

All previously known solutions to this problem, such as replaceable siphon cartridges, interchangeable valves, are expensive and require additional tools.

Object of the present invention is to overcome the disadvantages of the prior art and provide waterless urinals, from which fallen solids and deposits can be easily removed without, as in disposable siphons or rubber membranes a

 Replacement or disassembly must be done and when replacing

Can escape channel gases. To achieve the object, the invention provides that the sequence is configured with a partition.

The solution according to the invention is achieved by providing the outlet of a urinal, which is designed as an S-shaped siphon tube, with a dividing wall. This ensures that a removal of solids or solids, such as objects, a waterless urinal

have fallen into it or a cleaning of deposits that can accumulate successively in the operation of a urinal in the drain can be done without disassembly of the entire siphon, since the solids or deposits by manual or mechanical removal, suction, etc. only up to the area of the partition in get the flow of the S-shaped siphon tube and can be removed from there.

The solids clogging the drain preferably always collect at the lowest point of the drain. As a rule, the lowest point of an outflow is the curved area of an S- or U-shaped siphon tube. The fallen into the urinal solids such as coins, cigarette residues, glass, etc. are deposited as well as deposits, caused for example by uric acid compounds by the inventive solution preferably before or on the partition and can not be substantially behind by the arrangement of the partition the

S-shaped curvature region of the siphon out into the drain direction channel. The partition prevents insofar that the entire

S-shaped siphon pipe can be clogged by solid or deposits or solids and deposits close the S-shaped siphon pipe throughout the drainage area. The S-shaped siphon tube according to the invention is usually arranged with the partition so that the partition wall in the vicinity of the apex of the curvature region of the S-shaped siphon tube, that is in the vicinity of the lowest point of

Curvature region of the S-shaped siphon tube is located. In this case, the partition generally projects halfway into the siphon tube, whereby a sufficient liquid passage to the channel is ensured. The embodiment of the subject invention with a partition wall is all the more important in waterless urinals, as no frequent, stronger movement of the liquids in the process, as is the case with rinsing water-operated urinals and the fallen solid or deposits not by a pressure movement again can be flushed out of the siphon. In waterless operated urinals can be a conventional cleaning of the process such as with the help of a

Spiral brush or coil spring cause deposits and

Objects are pushed deeper into the process, without the possibility to carry them with the help of a rinsing process again out of the expiration out.

The subject invention, including the S-shaped siphon tube, may be made of any suitable material resistant to water and urine, such as plastic, ceramic, metal or glass, and is constructed such that the partition is both a one-part and a multi-part component of the S-shaped siphon can be configured. The partition wall and the S-shaped siphon tube are so far produced in one piece without an additional fastener is required or that the partition and the S-shaped siphon tube are connected via an additional fastener with each other.

A one-piece design has the advantage that when using materials such as plastic, metal, ceramic or glass, the S-shaped

Siphon tube in one operation, that is, a pressing, a casting can be made and no attachment of the partition with the

S-shaped siphon tube is required. There are so far no additional operations such as drilling, milling, etc. required for the production of the partition. The partition is thus as one piece or one piece

Part of the S-shaped siphon tube ausgestaltbar. Furthermore, it is also possible that the S-shaped siphon tube is constructed in several parts with the partition, that is, that the partition wall is connected via fastening elements with the S-shaped siphon tube. In this context, fastening elements are to be understood as connections of the partition wall with the S-shaped siphon tube, as they are

For example, by hinges or by tongue and groove fasteners can be done. Although this has the disadvantage that, in contrast to a one-piece design several operations such as holes, fittings, milling and fitting are required to ensure the conditions for attachment of the partition on the S-shaped siphon pipe. However, a multi-part design of the S-shaped siphon pipe with partition has the advantage that the partition is interchangeable in case of damage and insofar disassembly or a complete replacement of the S-shaped siphon pipe can be avoided with the partition in case of damage or destruction.

The multi-part invention solution is designed so that the

Partition is at least partially movable attached to the S-shaped siphon tube. The mobility can, for example, by a cylindrical

Tongue-spring attachment or a hinge can be ensured, whereby at least partially an axial rotational movement of the partition wall in the direction of the inlet or outlet of the S-shaped siphon tube is made possible. The cylindrical tongue and groove connection or the hinge can do so

be formed that up to a certain angle, either in the direction of the inlet or the outlet of the S-shaped siphon tube, a movement can take place, but from a certain angle of rotation, the movement is locked. When removing solids that are in the drain of the

S-siphons have come into contact with them or when cleaning the drain of deposits, fingers, hands or removal or cleaning devices must be introduced into the drain and mechanical movements performed. In this case, shocks can act on the S-shaped Siphonrohrwandung and the partition and cause damage to the S-shaped siphon tube and / or the partition. Mobility of the partition is advantageous in that that it yields when touched and the risk of damage to the S-shaped siphon tube and / or the partition wall is reduced. To

Contact and rotation of the partition wall further deeper penetration of solids or deposits during subsequent operation of the subject invention is prevented by the partition after returning touch returns to its original position or can assume their original position again. The starting position is usually a right-angled position relative to the S-shaped siphon tube. Another inventive feature is the flexible design of the partition. This is ensured by the fact that the partition consists of a flexible material, including in particular plastic counts. Due to the flexible design, the partition may have sufficient elasticity even without fasteners to a deeper penetration of

To prevent solids and deposits in the direction of the channel in the S-shaped siphon tube and at the same time allow yielding on contact, to prevent unwanted damage to the S-shaped trap and / or the partition. The material of the partition can thereby

For example, made of plastic such as polypropylene, polyethylene, polyvinyl chloride, polyethylene terephthalate, wherein the use of other

 Plastics possible and the list is not exhaustive. In multi-part design of the S-shaped trap and the partition, the

Partition wall and the S-shaped siphon tube made of the same material or be made of different materials. Thus, the S-shaped siphon of materials such as metal, glass or ceramic and the partition wall made of plastic and vice versa.

In addition, the flexible design of the partition has the advantage that in multi-part embodiment of the invention solution also

Fasteners can be used which have no

Allow rotation of the partition. Thus, a simple spring-groove connection without cylindrical configuration, ie by an elongated, angular recess with angled spring as a mounting connection serve between the partition and the S-shaped siphon tube. The flexible design of the partition ensures mobility and thus a sufficient elasticity in contact, as they can take place of solids and in the cleaning of deposits.

The partition is in a particular embodiment of the

Subject of the invention in the area of a belly-like extension of the

S-shaped siphon pipe arranged. The bulbous extension can occupy an area from the beginning to the end of the S-shaped curvature region of the S-shaped siphon tube. Under bulbous extension is to be understood in this context, an increase in the diameter of the S-shaped siphon tube in the curvature region. The increase in diameter may be concentric or eccentric. The increase in the diameter of the S-shaped siphon tube in the region of the curvature has the advantage that solid or deposits at the lowest point of the

 S-shaped siphon tube can deposit, but without a closure of the S-shaped siphon tube takes place. Due to the arrangement of the partition in the

Area of the belly-like expansion prevents solid or debris from being removed or cleaned into an area of the abdomen

S-shaped siphon tube, which lies beyond the bulbous extension in the direction of the channel, so that the flow to the channel can not clog and a sufficient liquid passage is ensured. The S-shaped siphon tube generally goes down vertically from the sump, is then returned upwardly through a lower bend, and is then connected via another bend to the drain to the channel. The shape of the S-shaped siphon tube in cross section is generally round. It can, however, take on all sorts of shapes, such as oval, quadrangular or polygonal forms. In the context of the present invention, in the waterless urinal, the S-shaped siphon connects the drain of the collecting basin with the outflow to the canal. In the present invention, the adjustment tube is inserted in a liquid-tight manner in the S-shaped siphon and has a smaller diameter than the S-shaped siphon tube. The outer diameter of the adjustment tube corresponds to the inner diameter of the siphon tube. The individual parts are connected with union fittings and gaskets.

In a particular embodiment of the present invention, the drain from the catch basin into the upper part of the S-shaped trap at an angle in the range of about 30 ° to 70 ° obliquely guided in a bulbous extended lower part of the siphon, wherein the oblique inlet through a vertical partition, which projects into the belly-like part of the siphon, is divided, and wherein the siphon from the belly-like part led back up and connected via a further bend with the drain to the channel. Blocking liquids for the urinals according to the invention are known per se. Preferred barrier fluids are poorly miscible with the effluent and have a density less than the density of the effluent.

For example, vegetative and biodegradable oils are mentioned as particularly preferred barrier fluids. In the context of the present invention, 0.3 to 0.8 liters of barrier liquid are generally used, based on a filling. The barrier liquid is generally added at the first

Commissioning and then added to each cleaning process. The cleaning agents are primarily suitable commercial

Cleaning agent in question. With about 10 to 20 liters of water, which is then poured into the catch basin of the urinal according to the invention, the deposits are washed away. This will be the entire contents of the urinal including the barrier fluid removed without opening the siphon. The barrier liquid must be replenished after the cleaning process.

In particularly stubborn cases, for example, when solids have entered the urinal, the siphon can be easily unscrew and

if necessary, clean mechanically.

Compared to known waterless urinals, the

Siphons according to the invention have a similar structure, as is usual in siphons for urinals with water flushing. The usual odor problems when cleaning waterless urinals can be determined by the selected

Completely remedy the design and type of cleaning of the urinals according to the invention. The waterless urinals according to the invention can be used for urinal formations for men and / or women WCs.
