Description

The invention relates to a odor remover on drains, drainage pipes or the like. _P with an overflow that retains a water seal and a baffle immersed in the water seal.

A Geruohverschluß can only fulfill its task, if a water seal is always retained »with normal inflow and outflow ratios of drains or the like» this is the case, as incoming water always remains in the water reservoir up to the level of the overflow and only that which rises above the overflow Water can run off. In certain cases, however, it may

come that apart from the pressure on the inlet side of the incoming Water, a suction force also acts on the drain side, e.g. through a suction or flushing pump connected downstream of the drain, such as the basement drain known from DE-OS 2% 07 24O. This suction force, which usually only acts for a short time, can be so strong that with the sucked off liquid also the The amount of air present between the baffle and the overflow wall is entrained and then the entire amount contained in the water seal The amount of water is also sucked off or flows off due to the siphon effect. The water reserve is then missing until it is below It takes a long time to find it again by adding a new water supply is refilled, and there is no odor trap for that long.

The object of the invention is to provide a scaffold seal that is secure against emptying.

The object is achieved according to the invention in that in the inlet direction seen in front of the baffle a part of the water reservoir separating partition with at least one narrow passage opening is arranged.

This ensures that a short-term on the drain side Occurring suction can only suck off the undivided part of the water reserve, while the divided part through the The throttling effect of the narrow passage opening is prevented from

The drain shown consists of a drain housing 1, which is covered at the top by an inlet grate 2 and has a drain connection J on the underside. Bas drain body 1 can be a partitioned chamber of a larger housing 4, in which e.g. a (not shown) evacuation or lifting pump is housed can be to raise the draining wastewater to a higher level.

A standpipe 5 is inserted into the outlet connection 3 , which is locked in place by means of a flap 6 and sealed by means of a seal 7. The standpipe 5 forms an overflow so that the water flowing through the grate 2 into the drain housing 1 is retained up to the level 8 in the housing 1 as a water reserve. The standpipe 5 is overlapped at the top by a bell 9, which is connected to the standpipe 5 by ribs 10 and the bottom edge 11 of which is a certain height difference lower than the liquid level 8, so that a sufficient smell is guaranteed.

Standpipe 5 and bell 9 are surrounded by a ring Partition wall 12, the upper edge of which 1? is significantly higher than the top edge I4 of the Ötandrohres 5. In the partition wall 13 are at intervals Slits 15 attached, the lower end of which is lower than the overflow edge I4 of the standpipe 5 and the one decreasing downwards Have width so that they are only in their lower part
