Electric steam iron

Claim 1

In an electric steam iron comprising a water reservoir fitted with a device for injecting water into a vaporization chamber formed in a sole-plate which is heated by a U-shaped electric resistor, the arms of the U being disposed along the two sides of the iron which have the greatest length and the point of injection being located in the vicinity of the base of the U and said vaporization chamber being adapted to occupy at least part of the space located between the resistor arms and to communicate with a distribution chamber through a partition-wall, said distribution chamber being in communication with the exterior through discharge holes having outlets on the underface of the sole-plate; the improvement wherein the vaporization chamber occupies substantially the entire space formed between the arms of the resistor and extends to the rear edge of the sole-plate, a communication between the two chambers being established by means of recesses formed in the partition-wall and located in the rear portion of the iron, the vaporization chamber having a substantially constant cross-section in planes at right angles to the normal direction of forward displacement of the iron and terminates at the rear end of the iron in a pluggable orifice which has substantially the same cross-sectional area.
