Abstract

A stream iron includes a support base, a handle, a reservoir portion which has an elbow-like water entry tube for preventing water stored inside the reservoir portion from spilling out when the steam iron is tilted forward, and an ironing plate having a bi-metallic plate. A related arrangement prevents water from flowing out of the ironing plate and getting clothes being ironed wet after the steam button has been pressed if the temperature of the ironing plate is lower than a certain minimum value.
