Definitions
- FIG 1 shows an iron soleplate according to the invention comprising an ironing sole 1 provided with steam passage openings 2, on which is fixed by any suitable means a heating sole 3 metallic provided with a heating means 4 constituted by example of an armored resistor.
- the heated sole 3 internally defines in a manner known per se, a room spray 5 connected by at least one channel 6 to a series of perforations 7 in relation to the orifices of vaporization 2.
- the entire heating sole 3 is intended to be closed by a cap 8 attached to said heating sole 3.
- the vaporization chamber 5 is in relationship with the iron tank (not shown) in the figures) by means of a bore 9 arranged at through the cap 8 above said chamber spray 5.
- iron ironing board comprises a spray 5 provided with a coating 11 (FIGS. 2 and 3), extending at least in part on the bottom of said chamber to promote the vaporization of water.
- the coating 11 comprises at least one layer of a material having hydrophilic and / or wettability properties intended for favor respectively, the spreading of water on the surface of the coating 11, and its absorption in the thickness of said coating.
- the coating 11 has also bonding properties favoring its adhesion On the bottom of the vaporization chamber 5.
- the coating 11 will be chosen from the materials having good thermal insulation properties of so as to constitute a thermal brake allowing a relative lowering of the chamber temperature spraying 5 to promote spraying.
- the coating 11 thus forms a first layer which can be advantageously chosen from materials such as sodium silicate, calcium carbonate, paints or varnishes, cements (Fiber Frax), compounds based on silica, carbonates, metal oxides, enamels, or compounds capable of being deposited in the form of a deposit plasma.
- materials such as sodium silicate, calcium carbonate, paints or varnishes, cements (Fiber Frax), compounds based on silica, carbonates, metal oxides, enamels, or compounds capable of being deposited in the form of a deposit plasma.
- the spray 5 has a grid above the covering 11 15 of water distribution.
- the latter preferably extends over the entire bottom of the vaporization chamber 5 and is advantageously in direct contact with said bottom.
- the grid 15 can obviously be arranged at a distance above from the bottom of the vaporization chamber 5, and by example at 1 or 2 mm.
- the grid 15 is provided, at least at least right of drilling 9 of means 16 of deflection and distribution of water on the surface of the coating 11.
- the deflection and distribution means 16 consist of a series of strips 16 (a) projecting above of the lower extension plane P of grid 15.
- the grid 15 defines as shown for example in the Figure 1, a series of openings 17 forming the mesh of said grid 15.
- the strips 16a surround at least partially, and preferably the openings completely 17.
- the height of the strips 16a from the plane P is advantageously of an average value between 0.5 and 5 mm, and preferably between 1 and 3 mm.
- the cross section of the strips 16a is advantageously comparable to a rhombus, one of the vertices is oriented in such a way that it constitutes the point the highest of the strap height as it is shown in Figure 3.
- the two upper faces 16b of strips 16a thus constitute deflection surfaces and distribution of the water intended to be vaporized, and thus evenly distribute the volume of water in the openings 17, and consequently over the entire surface of the vaporization chamber 5.
- the surfaces 16b may well obviously be flat or curved, or even can be irregular and for example provided with notches or ridges.
- the shape of the openings 17 can be hexagonal, in nest bee, square and is preferably also assimilable to a rhombus.
- the grid 15 is produced in a expanded metal, preferably aluminum or alloy aluminum, or even any other stainless metal.
- the coating comprises in addition to the first layer coating 11, a second layer 20 consisting of a permeable, filamentary and / or fibrous material having hydrophilic and wettability properties.
- the second layer 20 preferably extends over the entire surface of the first coating layer 11, and is chosen from materials such as glass mat, felts or fibers aramids (NOMEX), mineral fibers, carbon, veranes (fiberglass), fabrics metallic, or expanded micro-metal fabrics.
- the second layer 20 can be made of a material having a shape mesh square or diamond for example, medium size lower than the mesh of the grid 15 in order to constitute a second level of bursting and channeling of the drops of water.
- the second layer 20 is made of a material including in its structure an element thermal conductor such as metallic paste aluminum or zinc. We thus jointly ensure at the second layer 20 both a distribution mechanical water drops across the thickness and at the surface of said layer 20, and a pre-vaporization of water by the additional thermal contribution provided by the dough metallic.
- the second layer 20 is advantageously made in a material with an average grammage between 30 and 500 grams per square meter and preferably between 100 and 150 grams per square meter.
- the grid 15 is held in abutment against the second layer 20 by any suitable means, for example using a plate 25 also ensuring the closure of the chamber vaporization 5.
- the grid 15 forms a cradle ( Figure 2), also extending against the walls side of the vaporization chamber 5, held in compression position by plate 25.
- the water from the tank is poured out through the piercing 9 in the vaporization chamber 5 and the drops of water undergo a first mechanical burst at the level of the grid 15 and advantageously strips 16a.
- This first mechanical effect ensures a first distribution of the drops in the vaporization chamber 5.
- the distribution of the drops of water is then accentuated during the passage of the drops to the level of the second layer 20 which undergo a spreading at level of the surface of said layer, then a diffusion and spreading in the thickness of said layer 20.
- the distribution of water drops can be considered optimal and complete at the level of the coating 11 thus forming the third level of distribution.
