And you’re forgetting that water needs huge amounts of heat to evaporate. The heat capacity of plastic is rather small in comparison, so a machine capable of quickly vaporizing water also has the power to melt crappy thin plastic.
Modern dryers usually have a safety thermostat, but lint buildup is still a big fire hazard, so there are obviously temperatures in significant excess of boiling here.
