Abstract

A portable humidifier is provided which includes an induction heating system. The system includes an inductor coil and a metal target which functions as a heating element. The metal target is positioned within a tray beneath the inductor coil. The tray is adapted for holding water. The target is coupled to a float, which allows it to move towards or away from the inductor coil depending upon the water level in the tray.
