Powerful Bathroom Ventilation

Explosive decompression of bathroom atmosphere
  [vote for,

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?   

       I like this.

       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.

       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.

       Vacuum Toilet Systems   

       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.   

aadean, Apr 27 2003

       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.
bristolz, Apr 27 2003

       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."
bristolz, Apr 27 2003

       Ah, you know what I meant.
FloridaManatee, Apr 28 2003

       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.
FloridaManatee, Apr 28 2003

       No, it was Heathrow.
FloridaManatee, Apr 28 2003

       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.
Worldgineer, Jan 24 2004

       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
