Abstract (en)
[origin: EP3179000A2] A damp-proof venting device comprising a proximity sensor switch, fan blower, two solenoid valves and a control unit, powered by an external power supply, vents toilet bowl malodour directly into the toilet's sewerage drain, bypassing the toilet's primary water trap via an independent pressure-driven air passage sealed by a secondary independent water trap. Said control unit regulates the operation of venting unit's air blower and two solenoid valves, thus ensuring directionality of displaced air during the venting stage as well as sealing the venting passage after use under all possible circumstances, all in synchronicity with the toilet's engagement by user. A slight variation of said device allows for retrofitting onto geometry and space-accommodating market-available toilet models.
