Definitions

  • the present invention relates to an electric steam iron of the kind comprising an injection device for letting a certain flow of water flow into a vaporization chamber from which the vapor formed escapes through openings formed under the sole.
  • the present invention aims to achieve a steam iron which allows to obtain a momentary surplus of steam with total and almost instantaneous vaporization, and without significant scaling.
  • the electric steam iron comprises a heating element overmolded in a boss of a soleplate, a main injection device linked to a water tank for injecting water into an adjacent vaporization chamber. to said boss, and an auxiliary injection device for injecting an additional flow of water in order to obtain a momentary surplus of steam.
  • This auxiliary injection device opens into the vaporization chamber above the boss containing the heating element, and the iron is characterized in that, in the zone where the auxiliary injection opens, the metal of the boss is thinned so bringing the heating element closer to the metal surface.
  • the temperature of the metal at the drop point of the secondary injection is very high, which provides rapid vaporization.
  • the thinned area of the boss is substantially planar and has a downward slope towards the vaporization chamber.
  • the flat and thinned zone has a widening situated to the right of the auxiliary injection point.
  • a soleplate 1 of steam iron comprises an armored electrical resistance 2 forming a heating element, arranged in a U and molded in a boss 3 integral with the soleplate.
  • the steam iron comprises, in known manner, a main water injection device (not shown), designed to drop water drop by drop into a vaporization chamber 4 located between the branches of the U of the heating element 2.
  • the drop point of this main injection is located in the region of the base of the U, in the vicinity of point 5.
  • the iron according to the invention also comprises, in known manner, an auxiliary injection device (not shown) which can be operated independently of the main device, in order to temporarily obtain an excess of steam.
  • This auxiliary device is placed so that the injection takes place above a point 6 located on the boss 3.
  • this thinned area 7 is flat. It is in relation to the chamber 4 and extends over a certain length of the boss. It has a downward slope towards the vaporization chamber 4.
  • the thinned zone 7 has, around the injection point 6, an enlargement 8 towards the vaporization chamber.
  • the main injection pale falls in the region of point 5 and partly vaporizes there.
  • the non-vaporized water flows into chamber 4 and finishes vaporizing there. Due to the large dimensions of this chamber, scaling is distributed over a large area, therefore in a very small thickness.
  • the auxiliary device is actuated which causes the water to fall on zone 7 in the vicinity of point 6. Due to the thinning of the metal of the boss, the surface of zone 7 is at a temperature very high, which causes almost instant vaporization of most of the water.
  • the non-vaporized water partially rebounds to fall as rain over the whole of zone 7 where it vaporizes, leaving a fairly thin distributed deposit of tartar. Due to the inclination of the zone 7, the rebound and the fallout tend moreover to take place preferentially towards the vaporization chamber 4.
  • the inclination also allows the non-vaporized water which wets the zone 7 to flow towards the chamber 4.
  • the enlargement 8 allows the water fall to still be in the interior area.
  • the invention makes it possible to obtain a total vaporization of the auxiliary injection, possibly terminated in the vaporization chamber 4, and almost instantaneous.
