  • Patent number: 7490423
    Abstract: This invention relates to a kind of electric iron for eliminating wrinkles from clothes and other materials. The electric iron has an ironing seat, which is composed of a soleplate, an ironing surface on the soleplate, and a heater that heats the soleplate. There are heater-shaped dented portions on the ironing surface where the heater is installed. This invention, with this structure, reduces a contacting area between the ironing surface close to the heater and clothes or other materials to be ironed, thus changing an uneven distribution of temperature on the ironing surface. Further, for a steam electric iron, steam sprayed out of steam outlets in a soleplate spreads to areas away from a heater through dented portions, thereby resulting in an effect of wrinkle elimination.
