Description

The invention relates to a drain pot for wastewater.

Drain pots (but not for gutters), which have an inspection device which comprise closable with a closure element openings are widely known. It is exemplary here on the DE 36 146 . DE 10 2006 053 751 A1 . DE 44 11 492 C2 . DE 24 34 895 A1 . DE 1 854 390 U . DE 1 826 194 U . DE 1 825 087 U . DE 1 854 795 U or DE 1 816 291 U as well as on the GB 211 358 A . EP 2 206 841 A2 . EP 2 216 449 A1 and the DE 21 14 379 A1 directed. The GB 211 358 A discloses an effluent drainage pot having an inlet box having a baffle wall terminating above a reservoir bottom to form an opening and having barriers protruding upwardly from the reservoir bottom and one of which defines a retention level forming a maximum liquid level to form an odor trap reservoir can be present in the inlet box and with an outlet box and a drain pipe socket, the outlet box receives over the barriers overflowing wastewater and passes into the drain pipe socket and further with an inspection device which includes a closable with a closure element opening through which the drain pipe socket is accessible the opening is lower than the barrier, ie below the retention level.

In the known drain pots the problem arises that on the one hand the inspection devices are not opened after some time, so the closure elements can not be removed, on the other hand, a complete cleaning of the drain pots is difficult.

The invention is based on the object, a drain pot of the type mentioned in such a way that its usability, especially with regard to a complete cleaning is ensured in a simple manner.

This object is achieved by a drain pot according to claim 1.

By this measure, it is first ensured that atmospheric oxygen is kept away from the opening and the closure element. This ensures increased durability. In addition, the water in the odor-trap reservoir can be easily removed by this construction, so accumulated particles are thus dissipated.

Preferably, the inspection device is arranged within the inlet box. This ensures easy accessibility.

The inspection device of the present invention further comprises a pipe stub which stands on the reservoir bottom and is open at the top and at one side to the outlet box and the pipe stub. This simple construction ensures easy manufacturability and good usability.

The outlet box preferably has a sloping towards the pipe socket bottom. This ensures that incoming dirt particles are supplied to the drain pipe socket with relatively high flow rate, so can not get stuck.

The submerged walls extend over several, in particular over two sides of the inlet box. This ensures that even suddenly occurring large amounts of water can be dissipated without interference.

The barriers preferably bound the reservoir on several sides, especially on two sides. This also leads to an improved removal of larger water flows.

Preferably, the emptying device additionally comprises a U-shaped bent hose. This can be used and then sucks off the liquid contained in the odor trap, whereby even larger dirt particles can be removed.

The closure element is preferably designed such that it can be inserted without tools into the opening, this can be inserted and removed from it. Since the opening is below the retention level, minor leaks, which would be large enough to emit malodorous gases, are readily accepted. These leaks are namely sufficiently sealed by the liquid level, with a flow of water and emptying the odor trap reservoir is still not done.

Preferably, the inlet box is formed on its upper side in a flange region so that a drainage channel can be connected. This ensures easy assembly with a simple construction.

In the following description, the same reference numerals are used for the same and like parts.

As in the Fig. 1 to 3 shown, an inlet box 10 is provided, which has on its two sides baffle walls 11 and 12, which end above a reservoir bottom 17 and thus form slot-shaped openings 13, 14.

Further outward, in the direction of the outer walls 23, 24 of the inlet box 10 out, protrude from the reservoir bottom 17 barriers 15, 16 upwards, which define the maximum liquid level, which may be present in the inlet box 10.

If the liquid level rises, the barrier 15, 16 flows over the liquid, which then flows into an outlet box 20. This outlet box 20 is formed by the outer walls 23, 24, floors 21, 22, a front wall 25 and a rear wall 26.

The bottoms 21, 22 of the outlet box 20 are arranged sloping in the direction of a drain pipe socket 30, so that the barriers 15, 16 overflowing water flows at a high flow rate in the direction of the drain pipe socket 30 the outlet box 20 along.

In the inlet box 10 or from the reservoir bottom 17 upwardly projecting an inspection device 40 is provided which comprises a pipe socket 43 which has an opening 42 at its top. On one side 44 of the pipe socket 43, an inspection opening 45 is provided, so that the interior of the pipe socket 30 via the opening 42 and the inspection opening 45 is substantially freely accessible. To close the opening 42, a closure element 41 is provided, which is preferably designed as a stopper, with its conical side surfaces tight in the opening 42 by hand, so without assistance a tool is used. This closure element 41 is preferably elastically deformable.

When the drain pot shown here is to be cleaned, a draining device 35 can be used, which comprises a substantially U-shaped tube which ends when inserted into the opening 42 with a free end in the vicinity of the reservoir bottom 17 and the other end in Direction to the drain pipe 30 opens. With a rapid insertion of the emptying device 35 in the opening 42, the liquid level is high enough so that liquid flows through the interior of the U-shaped tube and then the well-known suction effect occurs. If this is not the case, then by supplying liquid, the liquid level can be raised so far that a filling of the U-shaped tube is secured. Then the emptying process takes place without further ado.

Finally, the inlet box 10 on its upper side outwardly projecting flanges 18, 19 and a channel-shaped inlet region, so that a correspondingly shaped gutter can be connected directly.

The details described above are described in particular with reference to Fig. 7 to 14 Again, it is expressly made to the disclosure of these figures including the dimensions there.
