- the material chosen can be polytetrafluoroethylene (PTFE, also known under the registered trademark Teflon®) which has the advantage of having excellent non-stick properties while being very resistant to heat.
- PTFE polytetrafluoroethylene
- at least one internal wall of the injection pipe 74 is coated with PTFE, so that the injection pipe 74 is resistant to high temperatures, in particular above 300 ° C. and has an internal wall with a coefficient of friction very weak, which limits a deposit of scale on the internal wall of the injection pipe 74.
- the injection pipe 74 preferably has a large internal section to prevent premature blockage of the free end of the injection pipe 74 for example.
- the internal section can typically have a diameter greater than 3 mm. Preferably greater than 4 mm.
- the wall of the injection pipe 74 may advantageously have a thickness greater than 1 mm.
- a ring of internal section of 6 mm and external of 7 mm in PPS (phenylene polysulphide) can be added to the injection pipe 74, in order to limit the heat transfer to the internal wall of the injection pipe 74.
- a ratio between the height of the vaporization chamber 71 and the diameter of the internal section of the injection pipe 74 is between 0.55 and 0.75, typically, the ratio is approximately 0.6 for a height of 4.9 mm and a diameter internal 3 mm.
- these dimensions have been optimized in order to guarantee the best possible scaling resistance while containing the dimensions of the various components.
- the portion forming the free end of the injection pipe 74 can have a specific shape making it possible to concentrate the possible accumulation of tartar in a specific area while providing an area where the liquid continue to enter the vaporization chamber 71 without being hindered by the accumulation of scale.
- the injection pipe 74 is bevelled at the free end forming the injection point as illustrated in FIG. 4A.
- the injection pipe 74 may include an opening extending substantially along the injection pipe from the free end forming the injection point.
- the opening has a shape allowing the liquid coming from the reservoir to flow into the vaporization chamber 71 even in the event of accumulation and deposit of scale at the free end of the injection pipe 74.
- the opening of the injection pipe 74 is a cut on a half-section of the injection pipe 74, extending along an axis substantially parallel to the injection pipe 74.
- the injection pipe 74 is arranged in the vaporization chamber 71 so that the cutout is on the side opposite to the wall forming the bottom of the vaporization chamber 71.
- the vaporization chamber 71 is closed by a plate forming a cover, this means that the cut of the pipe 74 is then oriented towards the plate forming the cover.
- the injection pipe 74 is distinct from the vaporization chamber 71, that is to say that it is not the same part.
- the injection pipe 74 projects inside the spray chamber 71.
- the opening of the injection pipe 74 comprises at least one slot extending along an axis substantially parallel to the injection pipe 74.
- the opening can comprise two slots extending on either side of the injection pipe 74.
- the internal surface of the vaporization chamber 71 is covered at least in part by a hydrophobic layer 9 positioned under the injection point.
- the hydrophobic layer 9 is then distinct from the injection pipe 74.
- the hydrophobic layer 9 makes it possible not to generate evaporation under the injection point but to push the evaporation further into the evaporation chamber 71, in order to do not store scale deposits under the injection site. Indeed, the hydrophobic layer 9 is characterized by a high surface tension.
- the hydrophobic layer 9 comprises polytetrafluoroethylene (PTFE).
- PTFE is a material resistant to high temperatures (especially above 300 ° C) and has a very low coefficient of friction, which limits the deposit of tartar at the injection point since water cannot remain there.
- the hydrophobic layer 9 is positioned only under the injection point. By this is meant that only a surface under the injection point is covered by the hydrophobic layer 9, which therefore does not entirely cover the internal surface of the vaporization chamber 71.
- the hydrophobic layer 9 can cover a surface between 10mm 2 and 2000mm 2 , preferably between 100mm 2 and 1000mm 2 , and more preferably between 500mm 2 and 600mm 2 .
- the hydrophobic layer 9 can cover the internal surface forming a bottom of the vaporization chamber 71, over an area of approximately 552 mm 2 .
- the hydrophobic layer 9 may have a planar shape, preferably substantially rectangular or triangular. It can also take a three-dimensional shape defined for example by inclined planes, making it possible to improve the sliding of the liquid to move the evaporation point away from the free end of the injection pipe 74. Such a three-dimensional shape can also contribute to distribute the liquid well when it arrives in the vaporization chamber, breaking the large drops and distributing them in smaller drops over the entire internal surface of the vaporization chamber 71. Thus, the efficiency of the vaporization is improved while reducing the risk of scaling (blockage) of the device.
- the shape of the hydrophobic layer 9 can also be produced during the manufacture of the vaporization chamber 71, typically by integrating the shape into the molding.
- the hydrophobic layer 9 has for example a pyramid shape.
- the hydrophobic layer 9 can have the shape of a truncated pyramid.
- the hydrophobic layer 9, if any, is formed by applying a hydrophobic material to an internal surface of the vaporization chamber 71.
- the hydrophobic material can be applied in the manner of a paint or a coating or sprayed on the internal surface of the spraying chamber 71.
- the hydrophobic layer 9 is an insert in the vaporization chamber 71.
- the insert is held in position in the vaporization chamber 71 by an immobilization device comprising a centering element 710 of the element added relative to the injection point.
- the centering element 710 comprises a centering half-pin 710a formed in the vaporization chamber 71 and intended to cooperate with a notch 9a of complementary shape formed in the insert 9.
- the internal surface of the vaporization chamber 71 comprises a hydrophilic layer 10, that is to say a layer characterized by a low surface tension.
- the hydrophilic layer 10 extends over all or part of the internal surface of the vaporization chamber 71.
- the hydrophilic layer 10 can be positioned only under the injection point, in the sense that only one surface under the injection point is covered with the hydrophilic layer 10.
- the hydrophilic layer 10 extends over the entire internal surface of the vaporization chamber 71, so as to maximize diffusion of the liquid.
- the hydrophilic layer 10 comprises a woven material, for example a glass fabric, which makes it possible to remarkably limit the phenomenon of calefaction.
- the vaporization chamber 71 comprises a hydrophilic layer 10 covered at least in part by a hydrophobic layer 9.
- the liquid injected at the point injection drops as a drop on the hydrophobic layer 9, and remains in the form of a sphere due to the high surface tension of the hydrophobic material constituting the hydrophobic layer 9, this sphere then sliding towards the hydrophilic layer 10, at a distance from the injection place.
- the hydrophilic layer 10 having a low surface tension, the drop of water can evaporate instantly. This reduces the appearance of tartar which will in any event be deposited if necessary at a distance from the injection site.
- the liquid vaporization system 7 can also include a second vaporization chamber or secondary vaporization chamber 72, in fluid communication with the first chamber 71 and occupies a second separate volume.
- the first vaporization chamber 71 is then arranged upstream of the second vaporization chamber 72 in the direction of the passage of the vapor.
- the transformation of the liquid injected into the vaporization chamber 71 into vapor takes place in at least two separate vaporization chambers (71, 72). This effectively retains unwanted tartar and improves the lime resistance of the styling appliance 1 and therefore its duration of use.
- the second vaporization chamber or secondary vaporization chamber 72 comprises discontinuities or obstacles by the presence of baffles 73 to create a labyrinth type path for the vapor.
- baffle 73 is meant any obstacle or barrier placed in the chamber creating uneven movements of the vapor, in a zigzag pattern for example, reducing the speed of passage through the secondary vaporization chamber 72, and increasing contact with the surfaces of the different walls of chamber 72. This makes it possible to vaporize any drops of liquid, and thus to ensure total vaporization of the liquid, the heat exchange surface being increased by the presence of baffles 73.
- the baffles 73 can for example be distributed parallel to each other. This allows the passage of steam according to a regular geometry, therefore trapping tartar in a homogeneous manner in the second vaporization chamber 72.
- the first volume occupied by the first vaporization chamber 71 is greater than the second volume occupied by the second vaporization chamber 72, or even at least twice greater, so as to allow rapid vaporization in the first volume, and to not not reduce the compactness of the spray system 7.
- the possible distribution chamber 76 can be arranged laterally to the vaporization chamber 71 and to the secondary vaporization chamber 72, preferably over substantially the entire length of the vaporization system 7.
- FIGS. 6A, 6B and 8A, 8B Specific embodiments schematically representing the vaporization system 7 during operation are given in FIGS. 6A, 6B and 8A, 8B, in order to illustrate the advantages provided by the characteristics described above.
- the injection pipe 74 comprises an opening with a cutout on a half-section, and the internal surface of the vaporization chamber 71 is covered with a hydrophobic layer 9 covering all or part of the internal surface of the vaporization chamber 71.
- a first instant T1 typically during a first use of the styling device 1
- the liquid coming from the reservoir is injected into the vaporization chamber 71 through the injection pipe 74, at the free end forming an initial injection point 1 1.
- the injected water evaporates on contact with the hydrophobic layer 9, at a vaporization point distant from the initial injection point 11, by a rapid increase in temperature. Since the liquid water injected may contain minerals, a gradual accumulation of limestone or tartar takes place at the end forming the initial injection point 1 1. A progressive deposit of tartar can take place inside the pipe d injection, until the end is blocked.
- a scale plug 12 clogs the end of the injection pipe 74.
- the water then flows into the vaporization chamber 71 at another injection point 11 ', located upstream of the injection pipe 74 relative to the point of initial injection 1 1. Water may possibly flow on either side of the injection pipe 74, or over the scale plug 12.
- the injection point 11 ′ is progressively shifted along the cutout of the injection pipe 74 throughout the use of the styling device 1, as a function of the scale accumulation. .
- the moment when the injection point becomes blocked by scale is remarkably prolonged in time, since it is necessary to wait until the entire length of the cut of the injection pipe 74 is blocked by scale so that water injection can no longer occur.
- the resistance of the device to scaling is considerably improved.
- the injection pipe 74 includes an opening with a slot at the free end, and the internal surface of the vaporization chamber 71 is covered with a hydrophobic layer 9 covering all or part of the internal surface of the vaporization chamber 71.
