    STEAM IRON SOLE WITH STEAM
    Field
    The present application relates to a soleplate of steam iron.
    Presentation of the prior art
    Since antiquity it has been known that a fabric can be ironed by combining heat with a mechanical action of traction on its fibers. Over time, ironing tools have evolved from smooth heated stones or pebbles, which were moved on clothes to dry irons. The observation had shown that the fibers were much easier to flatten or shape if they were moistened, and that the preservation of these states was related to the temperature and the speed of drying.
    This was the reign of the method of ironing the "wet tab" consisting of interposing a wet cloth between the sole of the iron and the fabric, which allowed to obtain a quality still considered today as being the best possible.
    With the appearance of electricity, it was created irons, first dry then steam, which allowed to remove the use of the "paw wet". Despite results in gaining time and practicality undeniable, they were lower than those obtained with the latter.
    The soles of these irons were manufactured in aluminum foundry and polished to obtain a state of surface and flatness compatible with the desired use. Their defect was a rapid fouling due to the carbonization of tissue particles embedded in the microporosities created by polishing.
    To solve this problem, soles were created composed of a heating part of aluminum foundry on which was reported a rolled aluminum cap, patent FR2593837 object describing a method of fixing between the two parts. The new material used supporting, without alteration, higher temperatures than foundry aluminum, allowed the application of various coatings or surface treatments as described in US4822686 patent describing the application of enamel coating in to improve the ease of maintenance and gliding irons.
    The distribution of the vapor below the surface of the sole was improved by an increase in the number of exit holes and / or the development of shapes dug under the sole. It is known, non-exhaustively, forms of water drops, blades or channels of multiple shapes. In use, it was noticed that the steam cushion fomé at the interface iron / fabric did not evacuate in all, especially under the central part, from where, locally, a non-negligible residual moisture in the ironed linen requiring a wait before storage.
    Several solutions were proposed. Patent DE452559 for example, relating to a sole comprising, in the front, a vaporization zone and, at the rear, a drying zone by distribution of superheated air. However, the speed of passage to the areas to be dried being incompatible with efficient drying, especially as the temperature of this air is insufficient, this solution has proved ineffective.
    Document US5532455 discloses a steam iron soleplate having, on its front part, lateral orifices and central steam outlet orifices fed by two distinct chambers, which constitutes a first vaporization range, followed by a first drying range devourwe outlet steam, going transversely from one edge to the other of the sole. This arrangement is repeated a second time extending to the rear of the sole. According to the holder, this alternation of spraying and drying ranges makes it possible to perform a double action that is supposed to ensure better smoothing. In reality, the ratio between the vaporization and drying surfaces is not sufficient to ensure total drying. In fact, remoistens a remaining area impregnated with the first humidification and concentrated steam under the center of the sole does not evacuate completely. The permanence of the folds is not assured. The fine analysis of the phenomenon showed that the steam was trapped under the central part of the sole, the explanation being that if the quantity of vapor emitted by the holes could, half, be exhausted in the open air along the edges, the other half had no way out, remained concentrated in the center by the shape given to the belt of holes on the periphery, or to the shapes of the distribution channels.
    The only part that was cleared was the back of the sole, it was necessary, in order to promote the flow of steam towards this zone during the ironing action, to create arrangements of the surface of the soles, hence the appearance of grooves. of all shapes and configurations, favoring this evacuation towards the rear and / or the sides.
    An improvement solution appeared with the creation of two-part soles with a heating part dressed with a cap. US 6189245 discloses a cap having separate vaporization and drying zones with about 30% allocated for vaporization; the rest, assigned to drying, having a coating consisting of a multitude of small pads between which the steam can escape in all directions. This provision, despite significant results in terms of performance, makes it possible to achieve the desired result only partially. summary

    The same elements have been designated with the same references in the various figures. For the sake of clarity, only the elements that are useful for understanding the described embodiments have been shown and are detailed. In particular, the internal components of a steam iron are well known to those skilled in the art and will not be described in detail.
    In the following description, when reference is made to absolute position qualifiers, such as "before", "backward", "up", "down", "left", "right", etc., or relative, such as the terms "above", "below", "upper", "lower", etc., or with qualifiers for orientation, such as the terms "horizontal", "vertical", etc., it refers to the orientation of figures or an iron in a normal position of use. Unless otherwise specified, the terms "approximately", "substantially", and "of the order of" mean within 10%, preferably within 5%.
    Figures 1 and 2 show a bottom view and a partial side view of a sole 5 of an iron. The sole 5 comprises two components: the first component is the cap and the second component is the heating subassembly, the cap covering the heating subassembly. In the remainder of the description, two embodiments will be described. In one embodiment, the sole 5 comprises a thick cap which is designated by the reference 10. The cap 10 may be an aluminum cap having a thickness for example between 1.5 mm and 2.5 mm. According to another embodiment, the sole comprises a thin cap which is designated by the reference 11. The cap 11 may be a cap made of stainless steel sheet or other material having a thickness for example between 0.2 mm and 0 , 6 mm. The heating subassembly, not visible in FIGS. 1 and 2, is specific to each type of cap and is designated by the reference 12 for the embodiment corresponding to the cap 10 and by the reference 13 for the corresponding embodiment. at the cap 11. Figures 1 and 2 are identical for the caps 10 and 11.
    The modifications made to the caps 10 or 11 with respect to conventional caps are distributed as follows: on the one hand modifications relating to the surface of the caps 10 or 11 in contact with the laundry which may be identical in all respects regardless of the material of the cap / and secondly modifications that are related to the attachment of the caps on their respective heating sub-assembly, specific to each type of cap, depending on their material.
    In Figures 1 and 2, which show the outer part of the cap 10 or 11 in contact with the laundry and which are common to both types of caps 10 and 11, there is a convex shape constituting a relief 15, also called curved portion, defined with respect to a reference surface, substantially flat, corresponding to the largest flat portion of the cap 10 or 11 in permanent contact with the laundry. According to one embodiment, it is in about one-third of the surface 16 for the vaporization, that open spray holes 20.
    The volume of the relief 15 is defined by a substantially flat surface 17 in the axis of the cap. The surface 17 is elevated with respect to the surface 16 and is located in a plane parallel thereto. A height h between 0.3 mm and 2 mm separates the two surfaces 16 and 17. The surface 17 occupies a portion of the total surface of the cap 10 or 11 in contact with the laundry which is between 10% and 40% .
    A line L1, shown in phantom in FIG. 1, represents the limits of the surface 17. The line L1 is defined by: on each side, portions of curves c1 and c2 substantially parallel to their respective capping edge 19 for cl and 21 for c2 and at a distance dl which can be between 25 mm and 45 mm, for example equal to about 35 mm; at the rear, a straight portion pl parallel to the cap heel 22 at a distance d2 which can be between 25 mm and 40 mm, for example equal to about 30 mm; and at the front, a circular portion r 1 tangent to the curves c 1 and c 2 having a radius which may be between 5 mm and 15 mm, for example equal to approximately 8 mm.
    The volume of the relief 15 is further defined by a connecting surface 18 between the surface 16 and the surface 17.
    A line L2, in solid lines, represents the limits of the surface 18. The line L2 is defined by a constant distance d3 between the lines L1 and L2, which can be between 10 mm and 25 mm, for example equal to about 17 mm. . This results in the line L2 by a curve portion c3 parallel to the curve portion C1, a curve portion c4 parallel to the curve portion c2, a circular portion r2 parallel to the circular portion rl, a right portion p2 parallel to the portion of line p1 and by two new circular portions: a circular portion r3 of center ol located at the point of intersection of the curve portion c1 with the right portion p1, and a circular portion r4 of center o2 located at crossing point of the curve portion c2 with the right portion p2.
    The junction surface 18 between the two lines L1 and L2 may be generated by the displacement of a straight line segment between the two lines, but it is preferentially defined by the circulation of a radius R of center situated on a perpendicular to the surface 17 in line with the line L1, defined as the location of the points of tangency between the radius R and the surface 17. The line L2 is defined as the location of the intersecting points between the radius R and the surface 16.
    FIG. 3 is a view similar to FIG. 1 of the cap 10 or 11 and FIGS. 4 and 5 are wes in section of FIG. 3 respectively along lines AA and BB in the case of a thick cap. FIG. 3 is a dashed line of hidden elements specific to the cap 10 and visible in FIGS. 4 and 5.
    In these figures, in addition to the modifications common to the cap 11, there are the following specific modifications of the cap 10: tubular shapes which are intended, among other things, to serve as hollow rivets 23 to ensure the connection between the rear part of the cap the cover 10, assigned to drying, and the heating subassembly 12. Their number, their distribution, and their manner of use are determined according to the chosen use. The tubular shapes 23 are positioned outside the surface occupied by the vaporization chamber.
    FIGS. 6 and 7 are sectional views of FIG. 3 respectively along the lines CC and DD in the case where the sole comprises the cap 10 and FIGS. 8 and 9 are sectional views of FIG. 3 respectively along the lines CC and DD in the case where the sole includes the cap 11.
    As shown in these figures, the heating sub-assemblies 12 and 13, in aluminum casting overmoulding a tubular heating element and comprising the vaporization chamber, are modified with respect to conventional heating subassemblies as follows: their common part ensuring contact with the inner part of the caps 10 and 11: the surface of their foundry, initially flat, is modified (FIG. 6), to reproduce the relief 15 which is positioned with reference to the vaporization holes present on each foundry and each headdress; for the rear part, reserved for drying, specific to the cap 10 of aluminum, orifices 24 are provided opposite each hollow rivet 23 (FIG. 7), in addition to those intended for rivets resulting from the manufacture of the spray holes. 20, and a chamfer 25 is created at the inlet of each orifice 24; for the rear part, intended for drying, specific to the cover 11 made of sheet steel or other material, the type of shape conventionally given to the edges of the subassembly 13 around its periphery (FIG. crimping.
    FIG. 10 illustrates an embodiment of a method making it possible to obtain the structure represented in FIG. 7. In this embodiment, the hollow rivets 23 are obtained by extrusion spinning, the ductility of the aluminum of the cap permitting to apply this method by which a movable punch under high pressure 30 is blocking the material while a cylindrical punch 31, sinking, flutes it to forge a rivet chimney of the desired height. For example, to form the hollow rivets 23 of internal diameter θ equal to 3 mm from a material thickness of 2 mm, and the penetration of the punch 31 being 1.5 mm, it is possible to obtain a stack of a height H of about 4.5 mm.
    According to one embodiment, the assembly between the cap 10 and the subassembly 12 can be made in the following way: for the front part, the extruded tubes of the steam outlet holes 20 are used, crimping being ensured for example according to the known techniques described in the patent FR2593837 / for the rear part, the hollow rivets 23 are used, proceeding by limited crushing of their end (visible in FIG. 7), the deformation generated, by driving the material into the chamfer 25 provided for this purpose ensures clamping between the two parts.
    According to one embodiment, the assembly between the cap 11 and the subassembly 13 can be achieved by preserving the conventional methods, by the use of the vaporization holes 26 and the crimping of the cap 11 on the periphery of the sub-assembly. together 13.
    Before positioning the parts against each other, care is taken to coat all the surfaces that are to be in contact with a thermally conductive grease that will prevent the formation of an insulating air gap between them.
    FIG. 11 is a sectional view of FIG. 3 along the line FF of another embodiment in which temperature sensors Ct are installed on the cap 10 inside certain hollow rivets 23 chosen as representative of the temperature of the cap.
    As can be seen in FIG. 9, reserves 27 can be provided in the heating subassembly 13 to allow access to the cap 11, each of these reserves 27 is crowned with a hollow cone 28, made from a foundry, of thickness for example between 1 mm and 2 mm, exceeding a height hl for example between 2 mm and 6 mm on the inside of the subassembly 13.
    FIG. 12 is a sectional view of FIG. 3 along the line FF of another embodiment in which temperature sensors Ct are installed in the reserves 27, arranged at points representative of the sole temperature to enable a access to the headdress 11.
    The retention of these sensors will be ensured by the deformation, either of the head of the rivets 23 as shown in FIG. 10 for the cap 10, or of the top of the hollow cone 28 as represented in FIG. 11 for the cap 11 and by the establishment of an elastic setting 29 ensuring the immobilization of the sensor.
    The collected information transmitted to a calculator and translated may be able to display, for example on a liquid crystal screen visible to a user, the nature of the fabric that can be ironed.
    Figure 13 is a sectional view of Figure 3 along the line G-G illustrating the operation of the iron. During ironing, at the surface 17 of the relief 15, the pressing pressure is concentrated because the contact surface with the laundry 32 is reduced. The residual moisture, trapped in the laundry 32 beneath this surface, subjected to heat and increased pressure, has the possibility of evacuating laterally, first in the space of height h formed between the surfaces 16 and 17 and then outward, as illustrated by the arrow V in Figure 13, under the effect of the displacement of the surface 18 which creates an open wedge shape towards the lateral edges of the sole. In addition to overall drying of better quality linen, the possibility of obtaining marked and persistent folds is real.
    The outer surface of each of the caps remains compatible with the application of known coatings, but the thermal conductivity can be improved by flash projection of boron nitride, for example, on the surface of the enamel slip before baking.
    It is furthermore desirable to obtain the disappearance of the folds of the fabric during its ironing.
    For this purpose, a lot of research was carried out which resulted in solutions, all oriented towards the improvement of iron / linen surface relationships: better wear resistance, better sliding, better evacuation of residual moisture or even better thermal transmittance. .
    Ironing performance can be defined as the best compromise between the factors: speed / quality / less arduous / less wear of the linen, it was remarkable to note that most of these actions were for the sole purpose of optimizing the relations aroused. It neglected the importance of the first action to which the fibers of a fabric are subjected during ironing, which is a mechanical action of tensioning the fabric through the edge of the sole, an observable phenomenon because any movement of the iron causes the appearance of a moving undulation, parallel to this edge. With the inserts with caps reported, this traction on the fibers is reduced because of, on the one hand, the radius of curvature of their edge due to their manufacture, on the other hand to the decrease of their coefficient of friction on the laundry. Improvements in these areas have, in fact, impeded the speed of fiber shaping because at equivalent humidification conditions, obtaining straight fibers by stretching the fabric is more efficient and faster than pressing it. on them to straighten them up. There is therefore a possibility of improving the ironing speed.
    An object of an embodiment is to substantially increase the ironing efficiency by improving the tension of the fibers from the first movement of the sole on the laundry.
    Figure 14 is a bottom view of a sole 105 of an iron. As described above, the sole 105 comprises two components: the first component is the cap and the second component is the heating subassembly, the cap covering the heating subassembly. In the remainder of the description, two embodiments will be described. In one embodiment, the soleplate 105 comprises a thick cap which is designated by the reference 110. The cap 110 may be an aluminum cap having a thickness for example between 1.5 mm and 2.5 mm. According to another embodiment, the sole comprises a thin cap which is designated by the reference 111. The cap 111 may be a cap made of stainless steel sheet or other material having a thickness for example between 0.2 mm and 0 , 6 mm. The heating sub-assembly, not visible in FIG. 14, is specific to each type of cap and is designated by the reference 112 for the embodiment corresponding to the cap 110 and by reference 113 for the embodiment corresponding to the cap 111. Figure 14 is the same for the caps 110 and 111.
    Figure 15 is a sectional view of the cap 110 or 111 along the line a-a. Figure 16 is an enlarged view of a portion of Figure 15 in the case of a thick cap 110 and Figure 17 is an enlarged view of a portion of Figure 16 in the case of a thick cap 110.
    As can be seen in FIGS. 14 to 16, the cap 110 made of aluminum and the cap 111 made of steel sheet or other material that is the subject of the invention comprise: a reference surface 113, for example substantially flat, corresponding to the part of the cap in permanent contact with the laundry; a surface 114 and a surface 115, for example substantially flat, substantially parallel to each other and to the edge of the cap, widths m between 0.7 mm and 1.5 mm, the surfaces 114 and 115 around the cap 110 or 111 / a surface 116, for example substantially flat, whose limits L are substantially parallel to each other and to the edge of the cap. The axis of symmetry of this surface 116, of width for example between 7 mm and 16 mm is located at a distance for example between 12 mm and 24 mm from the edge of the cap. Spray holes 120 open on this surface 116 and define its length which will be adapted according to their number; and a surface 117, for example substantially flat, substantially parallel to the limits L of the surface 116 of width for example between 0.7 mm and 1.5 mm.
    In FIG. 14, two possible arrangements of the surface 116 are shown. In the right-hand portion of FIG. 14, there is shown a surface 116 that extends from the front of the cap to the cuff heel while in the left part of Figure 14, the surface 116 extends from the front of the cap to half of the cap. Preferably, the surface 16 is distributed in the same way along two lateral edges of the cap.
    The surfaces 114, 115, 116 and 117 represent the basic modifications of the cap 110 and 111, but it may be added, if necessary, other surfaces of different shapes but similar characterizations such as surfaces 118 and 119.
    The surfaces 114 to 119 are in depression relative to the reference surface 113. They are obtained by creating recesses (visible in particular in Figure 17), height h for example between 0.15 mm and 0.4 mm. Each height h of recess generates a leading edge 121 and 122 for those in contact with the reference surface 113, a leading edge 123 for the one in contact with the surface 114, a leading edge 124 for the edge intersection between the edge of the cap and the surface 115, and a leading edge 125 for the one in contact with the surface 117. Consequently, the surfaces 114 and 117 are on the same plane, as well as the surfaces 115 and 116.
    According to one embodiment, to avoid an effect of wear of the laundry, each leading edge has a same radius r, for example between 0.2 mm and 0.3 mm, which is for example developed by stamping and / or semi-cutting to ensure its dimensional regularity and a clean and smudge-free surface.
    For the manufacture of the caps 110 and 111, the quality and the dimensional guarantees of the leading edges are obtained by implementing different processes according to the material of the caps.
    FIG. 18 illustrates an embodiment of a method of manufacturing the cap 110. For the preparation of the surfaces 114, 115, 116 and 117 as well as, if necessary, surfaces 118 and 119, the process is carried out by stamping, playing on the ductility of aluminum to move the material from its initial form, indicated by the dotted line Ei, to its definitive form Fd. The cap is introduced into the tool after the edge-lifting operation and then positioned on the docking plane Pa of the dies 125 and 126 comprising, in hollow, the shapes of the attacking edges 121, 122, 123 , 124 and 125 of radius r. The cap is held pressed against the plane Pa by a blank greenhouse 127. A punch 128 is then penetrated whose shape and depth of penetration have been studied to move the quantity of aluminum just needed so that all the empty spaces are filled. .
    Figure 19 illustrates an embodiment of a method of manufacturing the cap 111. It is carried out by semi-shearing. Once the cap is positioned and held in place by a blank holder 129 on the dies 130 and 131, the cutting punch 132 is lowered to these dies, into which it is penetrated by the height h.
    FIG. 20 is a detailed view of FIG. 19. The radius r of the leading edges ba is obtained by playing on the clearance j between the cutting punch 132 and the dies 130 and 131. It is this game j which adjusts the cutting output radius until the desired radius r is reached.
    According to one embodiment, the heating subassembly 112, consisting of an aluminum casting overmolding a tubular heating element and comprising the vaporization chamber, is modified in the following manner which applies equally to the aluminum caps 110 that for 111 caps made of steel or other material.
    The manufacture of the depressions of the surfaces 116 and 117 generates inversely and in relief with respect to the inner face of the cap of the projections 133 and 134, as can be seen in FIG. 16. The foundry of the subassembly 112 will be modified accordingly to house the protrusions 133 and 134 at most just.
    One embodiment of a method of assembly between the caps 110 or 111 and the heating subassembly 112 will now be described.
    Figure 21 is a sectional view of the sole shown in Figure 14 along the line d-d. For the caps 110 and if the option to create steam holes to the back of the sole was chosen as shown in Figure 14 for the left side of the sole 105, the crimping technique is used. using the steam holes described in the patent FR2593837.
    FIG. 22 illustrates an embodiment of a method of assembly between the cap 110 and the heating subassembly 112.
    If the option chosen is that of a sole with separate vaporization and drying zones, in particular as described in US Pat. No. 6,189,245, crimping is carried out using the steam holes in the vaporization zone, and for the zone drying in the rear part as shown in Figure 14 for the right part of the sole 105, devoid of fastening means, locally created notches of width R, for example between 2 mm and 4 mm by pressing a blade 135 , of corresponding width, to form a chip 136 with a thickness greater than half a thickness of the cap sheet, the latter by falling back on the edge of the heater assembly 112 will locally clamp between the two parts. There will be as many crimping points, according to this method, as necessary to ensure perfect contact between the inner surface of the cap 110 or 111 and that of the heating subassembly 112.
    For the caps 111, whatever the chosen option, the current known fastening methods are retained.
    Before positioning the parts against each other, all the surfaces that are to be in contact with a thermally conductive grease will be coated, which will prevent the formation of an insulating air gap between them.
    Figure 23 is a sectional view of Figure 14 along the line c-c illustrating the operation of the iron. During ironing, at the level of the fabric 137 to be ironed, the repetition of the traction (zone T) exerted by the movement of the iron (arrow D) on the laundry by the plurality of leading edges improves the speed of its setting. flat or fold formation.
    Various embodiments with various variants have been described above. It is noted that one skilled in the art can combine various elements of these various embodiments and variants without being creative. By way of example, the surfaces 114 and 115 of the soleplate 105 described with reference to FIGS. 14 to 23 may be implemented with the soleplate 5 described in relation with FIGS. 1 to 13.
