PROBLEM TO BE SOLVED: To provide a portable dryer with a multi-setting function.SOLUTION: A dryer circuit including a main circuit and a connection controller is provided. The main circuit includes a power-source unit, a first heating unit, a second heating unit, a first switch, a second switch, a fan motor, a resistance, a first diode and a second diode. The first and second heating units are connected to a ground terminal via the first and second switches respectively. The resistance is connected between the first heating unit and the fan motor. The first diode is connected between the second heating unit and the fan motor. The second diode is connected to the resistance in series, and connected between the first heating unit and the fan motor. The connection controller adjusts the power to be provided for the first and second heating units and the fan motor by controlling the first and second switches. |
