  • Steam iron with scale deposit repression
    Patent number: 6163990
    Abstract: A steam iron of the present invention is aimed at spraying a stable steam by repressing deposit of scale when producing the steam, and at reducing the scale that adheres to clothes by miniaturizing the scale particles. The steam iron includes a scale deposit repressing device for repressing the deposit of scale by dissolving phosphatic compound into water in a water tank that stores the water for supply to a vaporization chamber.
