Drain optionally with or without odor trap

The innovation concerns a drain for the floor, ceiling, roof or the like. with a transition immediately adjacent to the housing

-pipe area to the horizontal or inclined outlet nozzle in the optional odor trap that can be inserted on the inlet side, can be used as a separate component.

Processes for the applications mentioned at the beginning are in each case according to the installation location and depending on whether there is odor nuisance are to be feared or there is a risk of freezing, with or without odor traps are required.

The previously commercially available processes are either with an odor trap equipped, or they have no odor trap. This means that for each application it must be specified beforehand which drain should be installed. If it turns out later that the decision made was wrong, one can Changes can only be made by replacing the entire process, with the resulting circumstances and costs.

For example, there may be cases in which the drains are to be installed in places that are not protected from frost, but the processes would have to be equipped with odor traps. Here then only heated processes come into question, or it must be done without odor traps, if the disadvantages are accepted.

It is true that processes are already known in which the odor trap is subsequently installed as a separate component for manufacturing reasons or is inserted removable for cleaning purposes. However, because of their different design, these processes are not optional can be used with or without odor trap, since a considerable amount, in particular because of the overall height and the arrangement of the outlet pipe sockets

-hood
Residual amount of drainage liquid remains in the drain ■■ body. Also, because of the great height, these processes are usually not suitable for installation in ceilings or roofs.

With the DT-OS 2.618.199 a sequence has been proposed that with an extremely low construction with a removable water seal insert is equipped, whereby the drain can be used either as a simple drain or as a drain with odor trap can. The water trap insert (odor trap) consists of at least 2 curved walls, which are connected by a web are connected to each other. One wall forms the baffle and the other forms the overflow wall. The walls are at their peripheral edges to Provide grooves for the sealing rings. On the outlet side, the drain body initially goes into an area with a larger diameter over. This is followed by the outlet pipe socket after a stepped shoulder. In the area with the larger diameter is the water seal insert is used. The upper peripheral edge of the baffle is on the upper inner wall and the lower peripheral edge the overflow wall on the lower inner wall of this area. By planting the lower peripheral edge of the overflow wall on the paragraph to The outlet pipe socket is supported by the water seal insert on the outlet side away. In a variant of this process, without a shoulder to the outlet pipe socket, are arranged to support the water seal insert on this and in the outlet pipe socket cooperating coupling parts.

However, this known procedure has various disadvantages. So is e.g. the flow cross-section on the outlet side through the step-shaped Paragraph to the outlet pipe socket or narrowed by the coupling parts arranged there. This results in optional use the drain without odor trap to the fact that a residual amount of liquid and dirt is retained by the paragraph and the dirt can accumulate on the paragraph, or that hair and other fibrous substances build up on the coupling parts, what can lead to complete blockage of the drain. Even if the water seal insert is installed, there is a risk of clogging because the flow cross-section here through the connecting web between the Walls is narrowed and fibrous materials also build up on this. Furthermore, a proper seal between the relative narrow edges with correspondingly thin sealing rings and the inner wall very questionable; especially because of this Sealing rings can easily jump out of the grooves when inserting the water seal insert.

The task of the innovation was to find a process and a suitable one To find odor trap, which can be used optionally with or without odor trap and in which the deficiency described cannot occur.

This task is achieved by the characterizing features of the claim 1 and solved by the further embodiment of the innovation according to the features of the subclaims.

The process according to the innovation can be used in an advantageous manner for cases of need find use both with and without odor trap. When used with an odor trap, this can be used if there is a risk of frost can be expanded in a few simple steps, with the process itself remains effective. The odor trap can also be used for cleaning purposes can be easily and quickly removed and installed. Here it is of particular advantage that you can use. a pry tool, the a Cams on the bottom of the case serve as an abutment, can attack the odor trap on one eye. The odor lock will with its that Transition area of the process adapted formed middle part pushed into the transition area or pulled out, with a rolling ring serves as a seal.

The transition area and the central part have a certain longitudinal extent on, over which the, on the closed perimeter of the central part adjacent, rolling ring unrolls and is thus inevitably moved into a sealing position. The sealing ring has come off impossible here. The splash around the odor trap works by contacting the inlet-side edge on the upper part of the circumference of the Transition area as the end limit of the built-in odor trap.

Due to the fact that both the transition area of the drain to the outlet pipe socket, as well as the odor trap, have no shoulders, fixtures or ribs, is in every installation case of the drain, regardless of whether with or without odor trap, there is a constant flow cross-section and therefore always full puncture capability of the process guaranteed.

Finally, the compact, simple design of the odor trap inexpensive production from materials suitable for this purpose to. A mechanical processing of the seat surfaces in the housing and on the odor trap is not necessary.

On the basis of the drawing, which shows the process in vertical section, is the innovation explained in more detail.

The drain housing 1 has an inlet area 2 which is covered with a grate (not shown). A transition area 5 a * ¹ *, which merges into the outlet pipe socket 4, adjoins the inlet area 2. The lower apex line of the transition area 5 forms a plane with the bottom 5 of the drain housing 1 and the outlet pipe socket 4-. The odor trap 6 has a central part 7 which is designed to be adapted to the transition area 3. With the middle part J , the odor trap 6 is pushed sealingly into the transition area 3 with a rolling ring 8 in between. Here, the flange 9 acts as an end delimitation of the inserted odor trap by resting against the edge 10. The odor trap 6 is a one-piece component and consists of the central part 7, to which, on both sides, oppositely angled approximately quarter-spherical sections adjoin as a dip wall 11 and as an overflow wall 12.

An eye 13 is arranged on the odor trap and a cam 14 is arranged on the bottom 5. With a lever tool 15 ' which the cam 14 serves as an abutment, the odor trap 6 can be pushed in or pulled out by engaging the eye 1J'.
