Hair dryers normally have 2 controls, one to adjust how much air it blows, and another one to adjust how hot the jet is.
When they're off, they don't blow any air so it would make sense to me to decide that the button to turn them on is the one that controls how much air it blows. It goes from 0 to 1 to turn on, so you just learned that that button changes how much air comes out of it.
But no, most of them do the opposite. So, you turn them on with the temperature control. The action is: no air, yes air, air gets super-hot if you keep pushing the button.
I can't find any modern air dryers where they get this right.
- wodenokoto 3mo agoI imagine it’s similar to why a fan starts at max. Eg: 0->3->2->1 Something technical made it easier to implement.
- aliher1911 3mo agoPossibly a consumer air dryer problem, something-something safety. Check professional ones like Parlux, the one I checked has 2 dials: airflow and temperature. Turns on by air dial. They are also conveniently under the thumb so you can adjust without looking.
- marcosdumay 3mo agoYes it's safety related. Turning the heater on while the airflow if off is a sure way to start a fire. It could be fixed with a relay or a solid state switch on the heater, or with a multipolar toggle on the airspeed. But that's several cents more expensive than making it turn on at the heater switch.
- altern8 3mo agoI'm not following, that's exactly what I want, I want the fan control to also turn off/on, so fan at 0 = off, fan > 0 = on.
