Definitions

  • the present invention relates to steam irons where vaporization occurs from almost instantly. These devices have a lifetime limited by scaling of the vaporization chamber.
  • Patent FR2757364 describes an embodiment of such a device where the diffusion of highly soluble sodium hexametaphosphate (HMPS) is controlled by a silicone matrix placed in the water circuit.
  • HMPS highly soluble sodium hexametaphosphate
  • the particles could be retained in the vaporization chamber by a metal screen as suggested in patent DE3006783 or the patent JP60160999. Sifting can also occur in a version of the patent FR2696197 where a grid intended to improve the vaporization has its edges raised in the shape of a basin.
  • a screening screen alone eventually causes blockage of the vaporization chamber with very large scale hard that does not drain.
  • the invention below relates to an anti-tartar device extending the duration of life of a steam iron by allowing regular evacuation of scale under a powder form invisible to the user, and avoiding blockage of the chamber as well as iron vaporization channels.
  • a steam iron having a circuit of water at least one compartment of which contains an anti-scale agent obtained by crosslinking or curing in an silicone elastomer of an organo system water vapor permeable silica comprising a hydrophilic active material and a polyorganosiloxane composition, the iron further comprising, near of the vaporization zone of a chamber formed in a heating body metallic, a grid, metallic in nature different from that of the body of heating, crossed by the steam flow.
  • hydrophilic active material is chosen from metaphosphates sodium or potassium.
  • the grid is mounted clamped between two walls of the vaporization of the iron.
  • the grid is coated with a layer of gold.
  • This layer protects the grid by making it stainless. We also see that it generates a large potential difference with a heating body in aluminum.
  • the grid is made of stainless steel.
  • the grid is protected from oxidation phenomena and creates a difference potential with an aluminum heating body.
  • the grid is made of expanded metal.
  • This arrangement helps break up the scale that comes to settle on or against the grid.
  • the anti-scale agent is contained in a tube and releases its material activated by at least one open end of the tube.
  • the silicone matrix can be molded into the tube without requiring any other mold.
  • the active material is released with kinetics of order one by a progressive front of cracks in the matrix which corresponds to the section of the tube and which is therefore perfectly controlled.
  • the tube containing the anti-scale agent is placed in the tank iron water.
  • the anti-scale agent may be in sufficient quantity to ensure good operation during the life of the iron, or can be interchangeable.
  • the disposal in the tank constitutes a simplification made possible by the molding in a tube.
  • Figure 1 is a simplified longitudinal section of an iron according to the invention.
  • Figure 2 is a simplified top view of the soleplate of an iron according to the invention.
  • the iron shown in Figure 1 comprises a sole 1 having a vaporization chamber 2, a reservoir 3 of water to vaporize, a drip system 4 allowing the supply of water from the vaporization chamber 2 from the reservoir 3, and an envelope 5 comprising an iron handling handle.
  • the reservoir 3 formed of two parts 300 and 301 assembled has an orifice filling 302 closed by a sliding cover 303. Inside this tank is arranged a tubular element 304 of constant section in which is molded a silicone elastomeric matrix 305 containing sodium hexametaphosphate (HMPS) in solid dispersion. This tube whose ends are open and reveal the silicone matrix 305 is placed so as to be wetted by the water contained in the tank.
  • HMPS sodium hexametaphosphate
  • the sole 1 has an aluminum heating body 100 which forms the walls from the vaporization chamber 2, a resistive tubular heating element 101, a closure plate 102 of the vaporization chamber 2, a cover 103 at thermal contact with the heating body 100 and intended to be in contact with the linen ironed on its outside with the iron.
  • the vaporization chamber 2 has a zone 200 more visible in FIG. 2 where the drop of the water drops.
  • the spray area widens on the dish of the sole in a region 201.
  • This vaporization zone is closed by ribs 202 and by a grid 203 preferably made of plated expanded metal of a thin layer of gold.
  • the grid 203 is mounted clamped between the plate closure 102 and the bottom of the vaporization chamber 2, so that the contact electric is provided between the plate 102, the grid 203 and the heating body 100. A potential difference is established between the grid 203 and the heating body 100, as a result of different metallic natures.
  • the grid has a mesh width of between 0.3 and 3 millimeters, the section of the mesh son preferably being angular, namely triangular, square or rectangular.
  • the grid is made of a metallic material different from that the vaporization chamber, in particular stainless steel, if desired covered with a layer of gold between 10 ⁇ and 100 ⁇ thick.
  • the bottom of the vaporization chamber 2 is covered by a anti-heat coating.
  • the steam produced can escape through passages 206 and channels 204 to vaporization holes such as 205 which lead to the ironed linen directly or via other channels of distribution located under the soleplate.
  • the silicone matrix 305 diffuses only very little hexametaphosphate by its free ends, even if the silicone matrix 305 is wet.
  • the user fills the water tank 3 with the orifice 302, the opening of which it closes with the cover 303.
  • the iron being hot, the tank rises to a moderate temperature but sufficient to accelerate strongly the diffusion of HMPS in water, the vapor diffusing towards the grains of highly hydrophilic HMPS which take up water, swell and break the network silicone.
  • the diffusion front of HMPS progresses slowly in the matrix in the axis of the tube along its constant section, and the diffusion is well controlled.
  • the length and the section of the tube are provided to ensure the diffusion of anti-scale product during the lifetime of the iron.
  • the tube and its silicone matrix are interchangeable.
  • the large scale left by the vaporization of water is in the form pulverulent thanks to the action of the HMPS and is partially evacuated by the steam.
  • HMPS is replaced by another phosphorus product hydrophilic.
  • the tartar is evacuated regularly invisibly and without disadvantage for the user.
  • the life of the iron is increased by the anti-scaling hydrophilic product, without this product causing such disadvantages only stains marking the ironed laundry.
