The reeking stench of number two lingers too long in the washroom, particularly if ventilation is weak or non-existent.
It is my conclusion that 100% of all the world's bathroom ventilation systems are simply weak.
The ideal bathroom ventilation system should be powerful enough to create
explosive decompression, completely venting the bathroom atmosphere and the offending odor (like the vacuum of space).
However, this involves rebuilding your bathroom into a space-frame pressurized chamber with an airlock plug door.
The bathroom would normally be pressurized when the occupant is taking a dump. Flushing and leaving the toilet seat arms the decompression cycle and the occupant has 10 seconds to escape, notified by red strobe lights, alarms and countdown annunciators before the airlock plug door is automatically sealed.
The room is explosively decompressed, thouroughly re-ventilated and deodorized, then repressurized before the airlock is opened for the next user.
The entire cycle takes 20 seconds.
Warning: any breach of the chamber will result in explosive decompression of your house, causing severe damage or collapse.

I dunno, I'm a little apprehensive about this for some reason. I'm not so sure that vacuum-pumping a bathroom, and the resulting implosion, is an improvement over the wrath of shite. Exhaust fans are called for. |
|
| |
You might also try eating less roughage at lunchtime. |

//The bathroom would normally be pressurized when the occupant is taking a dump// You mean there's circumstances where the kids will be dropped off at the pool in a depressurized atmos? |
|

Surely you could have an outside activation panel, so you could decompress it manually outside the loo. To prevent any 'hilarious' jokes occuring whilst someone is on the loo, the system would only activate once its aware someone isn't in there. |
|
| |
Wow, exciting, fun, and practical. Ok, well 2 out of 3 ain't bad. Croissant. |

Welcome, [Kalamity], to the HalfBakery. |
|
| |
Or you could use a low-yield fuel-air device (non-stoic) to generate a bulk overpressure that vents through a duct, then sucks fresh air back in during the resulting cooldown. The flamewash would burn up the (organic) odour molecules, and sterilise all surfaces, too. |
|
| |
But, whatever - croissant. |
|
| |
Not explosive (could be though), but in the halfbakery tradition, I keep visualizing a giant piston in a cylinder situated above the building that is drawn upward by the action of a huge crankshaft to draw all of the air out of the bathroom. |
|
| |
a few unrolled squares of toilet paper and whoosh - the whole roll disappears up, up and away. |

Guys take a look at this toilet contraption from the UK www.airloo.com it was patented last year and has taken off in the UK very well. |
|
| |
The airloo sucks all the smells out of the bowl and either filters it or pushes it outside. |
|
| |
Uh, yeah, that's great if you want to stick your face in the bowl and have a big sniff. What about the rest of the room? |
|
| |
Great first idea, [Kalamity]. |
|
| |
Buy a spray-booth and use it as an outhouse. |
|
| |
IMO, the problem is not so much the power of the fan as the availability of inlet air. |
|
| |
When my bathroom door is opened, you can hear the increase in fan noise pitch as the elimination of the negative back-pressure in the small bathroom allows the fan to spin faster. |
|
| |
The problem is opening the door when you have guests is a sure way to end a party. |
|
| |
Ordinarily, I simply open the only window, just below the exhaust fan. It's sub-optimal, because it's too close, but the fan does a better job than with it closed. |
|
| |
In ventilation system engineering "inlet air" is generally known as "makeup air." |
|
| |
Ah, you know what I meant. |
|
| |
Hey, maybe they could use the system they have on airplanes. Attach a suction device so it works at sea level and increase the duration of the vacuum. |
|
| |
BTW, how do airplane toilets work? I lived under the approach path near an airport once, and lying on my sun-lounger, never once got rained on. |
|
| |
It would need plenty of fail-safe devices. One of the characters is killed off in a homicidal similarly-equipped bathroom in the novel 'Gridiron'. |
|
| |
Croissant just for the millions of entertaining possibilities of Darwin Awards on this one! |
|
| |
Better lock down the toilets as well. Otherwise you're looking at explosively decompressing the sewer system into your house. |
|

Interesting to see airloo.com put a
concept in the market I invented
24 years ago. Unfortunately the
airloo system looks rediculous. |
|
| |
Here's the "do it yourself" tip/
invention, free of charge - just tell
you heard it from me (note I
mentioned smell free toilets in my
profile years ago): |
|
| |
Suck the air out of the flush tank
with a fan (also seat-switch
activated) and either vent it away
via a tube (to the ceiling vent
which virtually every toilet-room
has) - or purify it like airloo does.
The trick is that you suck the foul
air from the bowl via the overflow
tube. You may need to seal the
tank-cover with some kit so it's
pretty much air tight. |
|
| |
For toilets where the tank is
connected to the bowl with a tube
- you can also suck the air away
from this tube via a T part. Make
sure the exit goes up - so no
water gets into the air-suck
branch of the tube. |
|
| |
Make yourself (or your family
members) happy, impress your
friends with your zero smell toilet! |
|
| |
Good luck, freshloo@avh.dds.nl |

I can't believe how well this picture I found goes with this idea, [link].
