ABSTRACT:
An ultrasonic iron comprises a metal ironing plate fixedly mounted therein, ultrasonic vibrators and amplitude amplifiers, and a power adjusting circuit provided on suitable inner side thereof, so that the power adjusting circuit is capable of driving the ultrasonic vibrator as to resonate the ironing plate with a high frequency as soon as the ultrasonic iron is switched on. Heat energy is thereby quickly and directly produced between the contact surface of the ironing plate and the clothes when the ultrasonic iron is moved on the clothes back and forth. The heat energy required for the pressing of clothes is available immediately upon the onset of operation of the iron.
