ABSTRACT:
A leakage current preventing means for a drier includes a power circuit connected to an AC source, a touch control circuit connected to the power circuit and having a touch control IC and a touch control terminal capable of actuating the touch control IC, an output circuit connected to the touch control circuit and having a control medium which can be triggered into conduction by a pulse output from the IC and controls two junctions of the fire and ground wires from the AC source for being power supplied, and a leakage current detecting circuit connected to the touch control circuit and including a sensor for detecting an impedance change in the drier and an actuating medium capable of being energized into conduction in response to the impedance change to enable that the IC has no voltage output which results in non-conduction of the control medium which in turn results in no possible leakage current between the two junctions.
