Abstract

PROBLEM TO BE SOLVED: To shorten a charging time, allow a control operation over a long time even with an ironing device disconnected, and reduce consumption power by connecting a plurality of capacitors of a power supply part in series to a control means at a charging process and in parallel thereto at a discharging process. SOLUTION: At the time of a charging process, commercial power supplied from an electrode part P3 is rectified with a diode 13 and the voltage thereof is lowered with a resistor 14. The power so processed is supplied to a capacitor 16, a Zener diode 17 and a control means 18 via a resistor 15, and to another Zener diode 27 via a resistor 19. Also, the power is supplied to capacitors of large capacity 28 and 29 connected in series via a transistor 22 for charging. When an ironing device is separated from a stand, the discharge current of the capacitor 28 flows from a diode 24 to the capacitor 16, the Zener diode 17 and the control means 18. On the other hand, the discharge current of the capacitor 29 turns on a switch 32, thereby connecting a circuit including the control means 18 to the capacitor 29 in parallel. According to this construction, quick charging and discharge time extension can be realized and consumption power can be reduced.

2 is supplied with power to the iron part 1 through the electrode parts P3 and P4, and when the iron part 1 is detached from the stand part 2, the iron part 1 is turned off, and even if the power supply parts P1 and P2 are touched, there is a risk of electric shock. It is configured so that there is no.

Next, the operation of the power supply section 12 will be described with reference to FIG. The voltage of the commercial power supply 5 connected through the power feeding part P1 provided in the stand part 2 and the electrode part P3 provided in the iron part 1 is rectified by the diode 13 and stepped down by the voltage drop resistor 14, and then the resistance is lowered.

Therefore, the cordless iron of the present invention solves the above problems by shortening the charging time of the capacitor and operating the control means for a long time even when the capacitor is detached.
The purpose is to reduce heat generation by reducing power consumption of resistors and transistors.
