Drainage device with multi-stage siphon odor barrier

Abstract

The invention provides a drainage. The drainage comprises the following components: an inlet side drain pot (3.6); a drain line (12) connected to the drain pot and a multistage syphon odor seal (3, 6-11), wherein the multistage syphon odor seal is provided with an internal air area; the drainage is characterized in that an air passage (13,14) is provided between the internal air area and a peripheral air field in the drainage on an inlet side and / or outlet side of the drainage.

Description

technical field [0001] The invention relates to a drainage device, for example for sanitary areas, such as floor drains for showers. Background technique [0002] Such drainage devices, in particular floor drains for showers, have been known per se for a long time. In addition to their main function of draining water from surfaces such as shower trays or floors and distributing it into the waste water network, drainage devices in most cases have the task of deodorizing. It is conceivable that unpleasant odors can escape from the waste water network, which can be blocked by so-called siphons, ie drain bends in correspondingly curved line guides. The anti-odor function requires a certain safety margin for the expected evaporation from the siphon and pressure fluctuations in the pipe network. The gas is forced through the siphon into the space in which the drain is installed. There are therefore different regulations and standards, such as EN1253, which maintain the odor bar...
