Okay this is a shitpost, but ffs don't try this. That's a small electric fan-forced oven. There's a nonzero chance the airflow will splash water all over the inside, which is absolutely not liquid proof. Water + electricity == bad.
I've got a small, cheap air dryer. I think it was maybe $25 when I got it? It's just got two settings - a knob to set the temperature and another knob to set a timer (analog timer that makes a ding noise when it's done)
Inside it's just a heating element like the ones you'd see on an old-school stove top, and a big fan to blow the hot air downwards. I doubt there's any electronics in it - it's probably just basic electrics. I don't think the heating element would like being splashed with a liquid.
