Since alot of splash comes from breaking surface tension in
the water like when you splunk a rock or what ever the
equivilent in your country is, the rock plunges though the
surface and creates a "hole" in the surface of the water,
when the water rushes back to fill this gap is when the large
secondary splash occurs. This is the one that gets you when
your sitting on the toilet. In a diving contest the surface
tension of the water is broken already using spraying jets of
water or bubbles comming up from the bottom of the pool,
what this does is break the surface tension of the water
already so like a wave when it is onshore the hole created in
the surface will "crumble" back into itself, this creates less of
a splash as the sides of the hole in the water do not slap
together. even though thats not the aim of the water or
bubbles it could be applied in a toilet so that the "splash
factor" is greatly reduced. By pumping bubbles though the
bottom of the toilet and or creating a current that constantly
swirls the toilet water the "splash factor" could be nearly
eliminated, those of us in cold cliamtes know how bad the
"splash factor" can be in winter when you have just got out of
a warm bed. The more agitated the water the less splashing
will occour.

It was hardly that bad. The Japanese would love this unless/if they have the plop-on-the-shelf, bother-to-clean-up loos. |
|
| |
I hate those loos with the little shelf - they have them a lot in Europe, especially Germany, and I think they're gross ..... |
|
| |
Come on UnaBubba, thats a waste of resources. Besides, that only catches the first stool. |
|
| |
I think splashback is the premier problem facing toilet designers today. |
|
| |
What exactly would the action be? Vortex, blend or jauzzi? |
|
| |
I was toying with the idea of a spinning blade just above
the waterline but this would be too noisy and messy, I
think a circular current with air bubbles being pumped
into it from the bottom and sides this would need to be
at a fast enough rate to agitate the water enough to
prevent the splash back and allow the water to crumble
when hit like white water. The whirl pool would stop side
splash although this isn't as big as the secondary
splashback it contributes to the secondary splash by
slapping back into meet in the middle. Priliminary
research is underway. |

This "toilet spa" will be turned on and off from the light
switch like the bathroom fan and heater. It might even
make a good foot spa after a long day on your feet.
[joking] The roar of the rolling rapid that you speak of
unabubba will also drown out the embarresing splashing
noises that are the subject of the "silent toilet" idea. |
|
| |
Oooooh, a whitewater toilet. That's interesting. You could set the rapids at different difficulty levels for the "rafts" in the water... |
|
| |
People pay actual dollars for recordings of bubbling brooks and ocean waves to fall asleep to. Now, they just have to set their toilet on bubbly mode. |
|
| |
Shelf on loos? What kid of "shelf" are you taking about? Do I want to know? |
|
| |
I believe he was referring to a little projection from the side of the toilet that sticks out to catch whatever foulies may fall. Then when you flush, the water washes them off the shelf and down the drain. |
|
| |
I expect you didn't want to know that. Neither did I. |
|
| |
I've done some reasearch today with a small fishtank pump
and a bubble stone and some bits of appropriately shaped
wood if anybody is interested. It seems like it works I
havent been able to make the amount of bubbles I would
have liked though. |
|
| |
Gultherme: How about one of those 12V car tyre inflators ? They have quite a high output when they're not pumping against a high back pressure. That might gibe you enough bubbles. You might need more stones to handle the flow, or a perforated pipe or gauze. |
|
| |
But fizzing up the water would eliminate the whole point of going to the loo, namely, spinning round and marvelling at what you just done. This is the thinking behind the shelf feature. |
|
| |
.... mayhap a little like reviewing one's own halfbakery postings ? |

Its also the best way to check for the early signs of colon cancer... |

Good in concept, yet some tings are not taken into account. Such a toilet would, in the process of making bubbles, send tiny water particles into the air. That means that any contaminants in the toilet, i.e. urine, feces, bacteria, would be sent into the air. A serious health hazard. Some contaminated particles of water are sent into the air already using a conventional flush toilet, and it eludes me as to why no one has came up with a way to eliminate this. But if a toilet were built around this idea it would pose a very large health risk. Sorry, but fishbone for you :( . |

|
| |
What about peeing at your own turds, is that ok? |
|
| |
one advantage of standing-water in toilet bowl is to seal the odor from wandering up your nose. the white-water toilet better have some powerful deodorant mixed in! |
|
| |
I was considering using sound waves or some other vibrations to break the surface tension. The smell would still be contained as long as the turd sinks. |
