Abstract (en)
[origin: WO2011153637A1] The toilet ventilation device is used for drawing air from inside a toilet bowl of a toilet having a toilet tank and having an overflow pipe located inside the toilet tank. The device includes an adaptor fitting over an opened top end of the overflow pipe. The adaptor forms a first bottom- opened chamber and a second bottom-opened chamber that are in fluid communication with one another through a restricted flow passage. At least one among the first and the second chamber is configured and disposed to surround the top end of the overflow pipe and creates an oversized hood extending substantially parallel to an outer wall surface of the overflow pipe. The open bottom of the first and of the second chamber is located below a filled water level. The device also includes an air conduit network extending between the outlet of the adaptor to outside the toilet.
