Negative Air Toilet

Toilet with built-in negative air pressure
  [vote for,

(First, Why is there a Product: Toilet Paper category and no Product: Toilet?)

For those wondering: No, This idea does NOT include STRONG negative air pressure.

Many bathrooms have negative air pressure fans built in to suck out the smelliness and some have suggested that we increase the negative pressure strength but i've been in a bathroom with too much of this, and it sucks the smell back up the floor drain and it didn't help. The problem with these systems is that they suck the smell right past out noses. If the smell is coming from the toilet, THAT is where you should have the negative pressure.

Toilets should come with a hole inside the bowl that hooks up to a hose that provides the negative pressure. This way, you get rid of the smell at the source. It will activate when the toilet seat gets sat on and a button gets pressed. While the person is on the crapper air rushes by his bum as the stench is carried away. When a flush is detected, it will suck air as well. When it is not being used, it will still suck, even if just a little, because you can't be assured that it went down and stayed down.

Advantages: Cleaner air, as the stench is not sucked past our noses. Less suction needed, or more effective suction use.

Disadvantages: Suction might suck up water if toilet overflows (must include overflow valve). Possible problems with cleaning the toilets and keeping cleaning products out of the air hole (the same hole (s) used to flush can be used to suck air, possibly providing a solution to this problem).

Fresher air, Can be applied to urinals as well.

       I think it's probably a good idea, but one thing bothers me. In operating theatres, there is positive pressure over the table to push microbes away from the patient. If there was negative pressure in the toilet, might this not attract bacteria? That might not be a bad thing, as there are all sorts of them, but i wonder what the effect of having all of them in the pan together would be.   

       Vacuum cleaners fill up with filth all the time of course, and that's not sanitary.
nineteenthly, Dec 07 2006

       On the operating theatre the positive air is most likely filtered, and this is understandable. Keep in mind that with conventional negative pressure mounted in the walls and ceilings, the bacteria is being sucked past out noses to get to the vent. The toilet vent assures that the air going past your nose is cleaner air, less bacteria.   

       Yes vacuum cleaners fill up with filth, and I feel bad for anybody who lives in a vacuum cleaner, but I feel better for anybody living outside of vacuum cleaners.

       Aircraft toilets have a similar idea.
Ling, Dec 08 2006

       Aircraft toilets use negative pressure to pull EVERYTHING down that drain, it is not just a ventilation solution. My solution is more down to earth. No HuMangous pressures needed.

       + (I waited long enough for someone to say it couldn't be done, so bun.)
Zimmy, Dec 08 2006

       twitch, my comment doesn't read so well: I meant aircraft toilets use a similar (not the same!) idea, and it works well.
Mmmm, that doesn't sound much better. Oh, well.
Ling, Dec 08 2006

       How about a toilet which, when you flush it, it releases a singularity which not only removes faeces, urine and toilet paper, but the contents of the bathroom, the bathroom door, the furniture and causes the house, the street and maybe the whole city to collapse through suction, along with any people who may happen to be around at the time? It would need to be operated by remote control in a concrete bunker some thirty-seven miles away and contravenes local strategic arms limitation treaties.

       [nineteenthly], it better be made out of gold, so we can sell it to some evil dictator if what you said was possible.
twitch, Dec 08 2006

       A non-execrable toilet idea!
ldischler, Dec 08 2006

       The negative air pressure unit in most bathrooms (which I affectionately refer to as the "Fart Fan") was originally designed to remove moisture from the air. It was never intended for removing offensive odors. I have seen instances where such a fan was also mounted beside the toilet for the purpose of evacuating the smell and quite frankly, it worked well.

       [twitch], that's not a bug, that's a feature! An overflow-proof toilet!
SledDog, Dec 09 2006

       oh, wow.! you're right. All's needed is an emergency drain before the neg air tube reaches the air filter (if you even need one, but I don't think so), so that would be great, just like sinks have overflow holes, why not toilets? Or are manufacturers just trying to give us some more crap.
twitch, Dec 09 2006

       Bun for nineteenthly's anno.   

       [edit] although you'd need a lot of singularities over the lifespan of the toilet... wait, no you wouldn't, one would suffice. You'd need a lot of toilets over the lifespan of the user... wait, no, still just one. No repeat customers though. I'm not sure that obliterating the next eight city blocks is what the poster has in mind here.

       No, not interested in TMD's (toilets of mass destruction).
twitch, Dec 10 2006

       After reading Chuck Palahniuk's "Haunted", I've been wary of anything involving negative pressure.   

       What about explosive diarrhoea? Surely that would hit the fan (giggle).   

       In case of a power surge: clench.
Abusementpark, Dec 10 2006

       I was going to post this idea and thought "surely someone must have thought of this before". And wadayaknow? Bun, of course.

       Plus: guess where I'm at while I write this...
PauloSargaco, Dec 02 2012

       This is not to be used on a cold day - a porcelain seat is bad enough without a cooling fan.   

       //Plus: guess where I'm at while I write this...//   

       I'll go first then: Bog-nor Regis? Craponne-sur-Arzon?
TomP, Dec 03 2012

       Had a suggestion of a very basic prototype version requiring a manual pump built into the seat it self. The sound could be a potential source of embarrassment but the subsequent lack of smelliness may be seen as a socially decent squeak. [+]
