Thermostat faucet
Uses bimetallic elements to keep your shower the temperature you want | |
I was thinking a while ago about ways to make the whole water temperature experience better, and thought about using a complicated electronic system to measure the temperature of the water downstream and mix the hot and cold upstream to keep the temperature constant.
Then the other day I realized
that a lot of the problems this would have with robustness, power use, etc. could be solved by making a completely passive, purely mechanical device that uses bimetallic elements to close and open valves.
Like those rotary thermostats that you turn, and a switch closes when the bimetallic strip pushes past wherever you turned it.
Instead, you could use bimetallic springs or something to close valves, so that the temperature always stays at the value you set it. So the faucet/shower control wouldn't be a "mix this much cold with this much hot" control; it would become a "aim for this temperature" control.

So, to understand, your invention idea centers upon the specific method of regulating water temperature at the tap rather than the idea of a faucet capable of maintaining a set temperature? The reason I ask is that such faucets exist but are usually electro-mechanical. |

...So, you might not any water out, or just a trickle, but you wouldn't get freezing (or boiling) water in abundance? Hmm..a large sticky one. |

Correct. The idea is to be completely passive and mechanical instead of electro-anything. |
