Topenair The Patented Odour Free Toilet By Jack Swan Topen

Since Thomas Crapper’s first water closet marketed in the 1820’s, there has been little or no progression to the humble toilet.

Our lifestyles have been transformed, we live in a virtual world, we have the internet, mobile phones and huge advancements in technology, yet still the toilet remains unimproved.

We enjoy all these advancements, yet put up with a toilet still basically the same as it was in the mid 1800’s We can flush away the waste but the foul odour is still very much with us!

We have learnt to put up with the odour and learnt to mask it with air fresheners but still it remains socially un-acceptable. Air fresheners are harmful to both ourselves and the environment.

I have spent the last ten years working on this problem. During this time, I have developed and patented a device which completely removes bad odours from the toilet bowl before they can contaminate the bathroom.

The Topenair toilet complies with all British Standards requirements.

The two main areas are; 1) The Extractor fan : This is traditionally used to remove condensation. The Topenair toilet’s extractor fan is uses a to remove both condensation and foul odours.

2) The Water Seal. British standards requires any appliance connected to the soil pipe to be fitted with a water seal. The Topenair toilet allows foul odours from the toilet bowl to be directed through its patented water seal out to the soil pipe.

How it works? Condensation is removed from ceiling height through the fan. Instead of exiting outside through expensive trunking, the condensation is carried down through a pipe to the patented water seal and out through the soil pipe. Foul air is also drawn through the rim of a standard toilet bowl and is directed through the patented water seal to the soil pipe. You will see that all pipe work is installed behind the cavity wall.

Please note! There are two ways that the Topenair toilet’s foul air system can be put into production. 1)The foul air can be removed through the rim of a toilet bowl. Although this would only need one small hole in the back of the toilet, it would need the involvement of a toilet manufacturer. 2)Through any back to wall toilet unit. This option is described later in this presentation and would not need any toilet manufacturers input.

Topenair prototype All parts and pipe work are are standard plumbing fittings and would be fitted within the wall cavity. The fan would normally be fitted at ceiling height, this image shows the fan foreshortened for ease of prototype transportation.

By following the direction of the red arrows, the root of the foul air can be traced from the toilet bowl to the water seal and hence to the soil pipe.

Patented water seal specialized parts. Please note these components are made from UPVC plastic. The same as all solvent weld plumbing fittings!

Why the Topenair toilet ? Costs: Installing a Topenair toilet is significantly cheaper than installing a toilet and an expel air fan, trunking etc Environment: The Topenair toilet eradicates the need for air fresheners which are damaging to the environment( children and expectant mothers). Germs: “Aerosolization” of germs from the toilet is eradicated. (smells are germs!), Embarrassment: Imagine the feeling of never being bothered with toilet odours again. 21st century: People are looking for a more and more sophisticated standard of living. People want the latest that technology can produce. Its about time a huge advancement is made to the humble toilet.

This is a very simple low tech solution to the very real problem of foul toilet odours. Thank you for watching.
