Abstract

The aim of the invention is to ensure the disinfection of sink drainage, preventing the proliferation of microorganisms, the formation of biofilms, and the entry of microorganisms into the room. The device (1) according to present invention contains the following main components: at least one UV-A light-emitting diode (2), a printed circuit board (4), a radiator (6) for the heat transfer from the UV-A (2) and UV-C light-emitting diodes (38), a fan (8) for cooling the radiator (6), a transparent drainage pipe (20) whose inner surface is coated with a photocatalytic titanium dioxide coating (64), a contour nut (22), at least one UV-C light-emitting diode (38), a programmable controller with a motion sensor (50), as well as a membrane (58) for ensuring one-way movement of liquids and stopping gases from entering the room from the sewage system. The UV-A light-emitting diode (2) and UV-C light-emitting diode (38) provide illumination of the transparent drainage pipe (20) in a perpendicular direction from the outside of the drainage pipe (20) to the inside along its entire perimeter.
