  • the first vaporization chamber 41 is provided in the central part of the heating body. It is bordered in its rear part by the peripheral wall 40 and is delimited in its front part by a dividing wall 45 which extends vertically from the bottom wall to the cover 5 and runs laterally between the two lateral parts 40A of the peripheral wall 40 following a V-shaped path substantially matching the shape of the contour of the heating body 4.
  • the first vaporization chamber 41 is supplied with water from the reservoir via an injection orifice 50 provided in the closing cover 5, facing of an evaporation surface arranged in a central zone of the first vaporization chamber 41, located between the branches of the first electrical resistance 7.
  • This central zone is bordered in its front and side part by an internal wall 44 which projects vertically from the bottom wall and extends to the cover 5, the internal wall 44 extending parallel to the partition wall 45 and delimiting with it a corridor 46 for the flow of the V-shaped steam flow which runs substantially above the first electrical resistance 7.
  • the steam flow can only escape from the central zone through a rear opening provided between the two ends of the internal wall 44, the bottom wall comprising in the vicinity of this opening rear a mounting stud 47 intended to receive a thermostat, not shown in the figures.
  • This thermostat is intended to regulate the electrical supply of the first 7 and second 8 heating resistors in order to maintain the first vaporization chamber 41 around a set temperature, possibly adjustable by the user, of the order of 150°C .
  • the second vaporization chamber 42 has the shape of a V-shaped cavity which is provided between the peripheral wall 40 and the partition wall 45 and which extends substantially above the first electrical resistance 7.
  • This second vaporization chamber 42 communicates with a steam distribution circuit 9, provided on a lower face of the heating body 4, by a through opening 48 provided at the front end of the second vaporization chamber 42.
  • the steam distribution circuit is formed by a cavity 9, visible on the Figure 5 , advantageously provided between the heating body 4 and the sole 2, this cavity 9 making it possible to supply steam to the steam outlet holes 20 of the sole 2.
  • the first vaporization chamber 41 is connected to the second vaporization chamber 42 by two connecting tubes 43 which are preferably embedded in the aluminum foundry of the heating body 4, the two connecting tubes 43 being advantageously arranged symmetrically with respect to the longitudinal axis of the heating body 4.

  • the operation of the iron 1 will now be described.
  • water is injected by the pump through the injection orifice 50 and is projected into the central zone of the first vaporization chamber 41.

  • the steam flow corridor 46 extending between the first electrical resistance 7 and the second electrical resistance 8, the temperature prevailing there is very high, which makes it possible to quickly heat the water droplets transported by the steam flow. steam.
  • the water droplets transported by the steam flow are then projected against the V-shaped end of the partition wall 45 where they are largely vaporized. Any drops of water passing through the connecting tubes 43 are then mainly vaporized in the latter, due to the routing of the connecting tubes 43 in areas of the bottom wall overheated by the first 7 and second 8 electrical resistances .
  • the steam flow from the connecting tubes 43 then flows into the second vaporization chamber 42 which extends above the first electrical resistance 7 so that any droplets still present in the steam flow are permanently located vaporized before the steam flow can escape, through the through opening 48, towards the steam distribution circuit 9 and the steam outlet holes 20 of the soleplate 2.
  • the iron 1 thus produced therefore has the advantage of having great compactness while allowing a significant steam flow while strongly limiting the risk of spitting water droplets whatever the orientation of the soleplate 2.
  • the fact of inserting tubes into the heating body 4 to establish the connection between the first vaporization chamber 41 and the second vaporization chamber 42 allows both to increase the path of the steam in the heating body 4 and to force the flow of steam to return towards the center of the heating body 4, in a zone where its temperature is the highest.
  • FIG. 9 illustrates a second alternative embodiment of the heating body according to the invention in which the connecting tubes 43 are not embedded in the foundry of the heating body 4 but run inside the first vaporization chamber 41, in the vicinity of the bottom of the latter along the first electrical resistance 7 and/or the second electrical resistance 8.
  • the first vaporization chamber and the second vaporization chamber can be connected by a single connecting tube.
  • the iron as previously described can be connected by a cord for transporting steam to a steam generating base.
  • the steam coming from the base and traveling through the cord will be sent into the iron through the injection port provided in the closing cover of the heating body.
  • the use of such a heating body in association with a separate steam generating base has the advantage of eliminating the risk of projection of water droplets, linked to the formation of condensate in the cord, through the outlet orifices of steam.
  • the first vaporization chamber can be supplied with water by means of a drip plug placed at the level of the injection orifice and the iron housing includes a reservoir of water ensuring the gravity feed of the drip bushel.
  • the closing cover may include several water and/or steam injection orifices opening the first vaporization chamber.
