Description

La présente demande de brevet revendique la priorité de la demande de brevet français FR16/53145 qui sera considérée comme faisant partie intégrante de la présente description.The present patent application claims priority over the French patent application FR16 / 53145 which will be considered as an integral part of this description.

DomaineField

La présente demande concerne une semelle de fer à repasser à vapeur.The present application relates to a soleplate of a steam iron.

Exposé de l'art antérieurPresentation of the prior art

Depuis l'antiquité il est connu qu'un tissu peut être repassé en combinant de la chaleur avec une action mécanique de traction sur ses fibres. Au fil du temps les outils de repassage ont évolué pour passer des pierres ou galets lisses chauffés, qu'on déplaçait sur le linge, aux fers à repasser à sec.Since antiquity it is known that a fabric can be ironed by combining heat with a mechanical pulling action on its fibers. Over time, the ironing tools have evolved from passing smooth heated stones or pebbles, which were moved on the linen, to dry irons.

L'observation avait permis de constater que les fibres étaient beaucoup plus faciles à aplanir ou à mettre en forme si elles étaient humidifiées, et, aussi que la conservation de ces états était liée à la température et la vitesse du séchage.The observation had shown that the fibers were much easier to flatten or shape if they were moistened, and also that the conservation of these states was linked to the temperature and the speed of drying.

Ce fut le règne de la méthode de repassage à la "patte mouille" consistant à interposer un linge humide entre la semelle du fer et le tissu, ce qui permettait d'obtenir une qualité encore considérée aujourd'hui comme étant la meilleure possible.This was the reign of the "wet paw" ironing method consisting in interposing a damp cloth between the soleplate of the iron and the fabric, which made it possible to obtain a quality still considered today as being the best possible.

Avec l'apparition de l'électricité, il fut créé des fers à repasser, d'abord à sec puis à vapeur, qui permirent de supprimer l'usage de la "patte mouille". Malgré des résultats en gain de temps et de praticité indéniables, ceux-ci étaient inférieurs à ceux obtenus avec cette dernière.With the appearance of electricity, irons were created, first dry and then steam, which made it possible to remove the use of the "wet paw". Despite undeniable time and practical results, these were lower than those obtained with the latter.

Les semelles de ces fers étaient fabriquées en fonderie d'aluminium et polies pour obtenir un état de surface et une planéité compatibles avec l'usage souhaité. Leur défaut était un encrassement rapide dû à la carbonisation de particules de tissus venues s'encastrer dans les microporosités créées par le polissage.The soles of these irons were made of aluminum foundry and polished to obtain a surface condition and flatness compatible with the desired use. Their defect was a rapid fouling due to the charring of tissue particles embedded in the microporosities created by polishing.

Pour résoudre ce problème, il fut créé des semelles composées d'une partie chauffante en aluminium de fonderie sur laquelle était rapportée une coiffe en aluminium laminé, objet du brevet FR2593837 décrivant une méthode de fixation entre les deux parties. Le nouveau matériau utilisé supportant, sans altération, des températures plus élevées que l'aluminium de fonderie, permit l'application de divers revêtements ou traitements de surface tels que décrits dans le brevet US4822686 décrivant l'application d'un revêtement d'émail en vue d'améliorer la facilité d'entretien et la glisse des fers.To solve this problem, soles were created composed of a heating part in foundry aluminum to which a laminated aluminum cap, object of the patent FR2593837 describing a method of attachment between the two parties. The new material used withstands, without alteration, higher temperatures than foundry aluminum, allows the application of various coatings or surface treatments as described in the patent US4822686 describing the application of an enamel coating to improve the ease of maintenance and the sliding of the irons.

La répartition de la vapeur sous la surface de la semelle fut améliorée par une augmentation du nombre de trous de sortie et/ou par l'aménagement de formes creusées sous la semelle. Il est connu, de façon non exhaustive, des formes de gouttes d'eau, de larmes ou de canaux de formes multiples.The distribution of the vapor under the surface of the sole was improved by an increase in the number of outlet holes and / or by the provision of hollowed out shapes under the sole. It is known, in a non-exhaustive manner, forms of drops of water, tears or channels of multiple forms.

A l'usage, il fut remarqué que le coussin de vapeur formé à l'interface fer/tissu ne s'évacuait pas en totalité, surtout sous la partie centrale, d'où, localement, une humidité résiduelle non négligeable dans le linge repassé nécessitant une attente avant le rangement.In use, it was noticed that the vapor cushion formed at the iron / fabric interface did not completely escape, especially under the central part, where, locally, a significant residual moisture in the ironed linen requiring a wait before storage.

Plusieurs solutions furent proposées. Le brevet DE452559 par exemple, relatif à une semelle comprenant à l'avant une zone de vaporisation et à l'arrière une zone de séchage par distribution d'un air surchauffé. Toutefois, la vitesse de passage sur les zones à sécher étant incompatible avec un séchage efficace, d'autant plus que la température de cet air est insuffisante, cette solution s'est révélée inefficace.Several solutions were proposed. The patent DE452559 for example, relating to a sole comprising at the front a spraying zone and at the rear a drying zone by distributing superheated air. However, the speed of passage over the areas to be dried being incompatible with drying effective, especially since the temperature of this air is insufficient, this solution has proved ineffective.

Le document US5532455 divulgue une semelle de fer à repasser à vapeur comportant, sur sa partie avant, des orifices latéraux et des orifices centraux de sortie de vapeur alimentés par deux chambres distinctes, ce qui constitue une première plage de vaporisation, suivie d'une première plage de séchage dépourvue de sortie vapeur, allant transversalement d'un bord à l'autre de la semelle. Cette disposition est répétée une deuxième fois en s'étendant jusqu'à l'arrière de la semelle. Selon le titulaire, cette alternance de plages de vaporisation et de séchage permet d'effectuer une double action censée assurer un meilleur défroissage. Dans la réalité, le rapport entre les surfaces de vaporisation et de séchage n'est pas suffisant pour assurer un séchage total. En fait, on réhumidifie une zone restant imprégnée de la première humidification et la vapeur concentrée sous le centre de la semelle ne s'évacue pas totalement. La permanence des plis n'est donc pas assurée.The document US5532455 discloses a soleplate of steam iron comprising, on its front part, lateral orifices and central orifices for steam outlet supplied by two separate chambers, which constitutes a first vaporization range, followed by a first drying range without steam outlet, running 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 supposed to ensure better smoothing. In reality, the ratio between the spraying and drying surfaces is not sufficient to ensure total drying. In fact, an area remaining impregnated with the first humidification is rewetted and the vapor concentrated under the center of the soleplate is not completely evacuated. The permanence of the folds is therefore not guaranteed.

L'analyse fine du phénomène montra que la vapeur était emprisonnée sous la partie centrale de la semelle, l'explication étant que si la quantité de vapeur émise par les trous pouvait, pour moitié, s'évacuer à l'air libre le long des bords, l'autre moitié n'avait aucune issue, restait concentrée au centre par la forme donnée à la ceinture de trous en périphérie, ou aux formes des canaux de distribution.The detailed analysis of the phenomenon showed that the vapor was trapped under the central part of the sole, the explanation being that if the quantity of vapor emitted by the holes could, for half, be evacuated 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.

La seule partie dégagée étant l'arrière de la semelle, il fallut, pour favoriser l'écoulement de la vapeur vers cette zone pendant l'action de repassage, créer des aménagements de la surface des semelles, d'où l'apparition de rainures de toutes formes et configurations, favorisant cette évacuation vers l'arrière et/ou les côtés.The only exposed part being the back of the sole, it was necessary, to favor 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.

Une solution d'amélioration apparut avec la création de semelles en deux parties avec une partie chauffante habillée d'une coiffe. Le brevet US6189245 décrit une coiffe comportant des zones distinctes de vaporisation et de séchage avec environ 30 % affecté à la vaporisation ; le reste, affecté au séchage, comportant un revêtement constitué par une multitude de petits plots entre lesquels la vapeur peut s'évacuer dans toutes les directions. Cette disposition, malgré des résultats sensibles en matière de performance ne permet d'atteindre le résultat souhaité que partiellement.An improvement solution appeared with the creation of soles in two parts with a heating part dressed in a cap. The patent US6189245 describes a cap with separate spray and drying zones with approximately 30% affected vaporization; the rest, assigned to drying, comprising a coating constituted by a multitude of small studs between which the steam can be evacuated in all directions. This provision, despite significant performance results, only partially achieves the desired result.

Selon un mode de réalisation, des capteurs de température sont installés à l'intérieur de rivets creux prévus dans la coiffe ou dans des réserves prévues dans le sous-ensemble.According to one embodiment, temperature sensors are installed inside hollow rivets provided in the cap or in reserves provided in the sub-assembly.

Selon un mode de réalisation, la semelle comprend des cinquièmes surfaces en dépression par rapport à la première surface, sensiblement parallèles entre elles et au pourtour de la coiffe et formant des troisièmes décrochements, de largeur comprise entre 8 mm et 14 mm, et situés à une distance comprise entre 12 mm et 24 mm du bord de la coiffe.According to one embodiment, the sole comprises fifth surfaces in depression relative to the first surface, substantially parallel to each other and to the periphery of the cap and forming third recesses, of width between 8 mm and 14 mm, and located at a distance between 12 mm and 24 mm from the edge of the cap.

Selon un mode de réalisation, les trous de sortie de vapeur débouchent sur l'une des cinquièmes surfaces.According to one embodiment, the steam outlet holes open onto one of the fifth surfaces.

Selon un mode de réalisation, les deuxièmes décrochements sont chacun de largeur comprise entre 0,7 mm et 1,5 mm, et de hauteur comprise entre 0,15 mm et 0,4 mm et les deuxièmes décrochements forment des bords d'attaque.According to one embodiment, the second recesses are each of width between 0.7 mm and 1.5 mm, and of height between 0.15 mm and 0.4 mm and the second recesses form leading edges.

Selon un mode de réalisation, la forme des bords d'attaque comprend un rayon compris entre 0,2 mm et 0,3 mm.According to one embodiment, the shape of the leading edges comprises a radius of between 0.2 mm and 0.3 mm.

Un autre mode de réalisation prévoit un procédé de fabrication d'une semelle de fer à repasser telle que définie précédemment, dont l'assemblage entre la coiffe et le sous-ensemble est réalisé :

Description détailléedetailed description

De mêmes éléments ont été désignés par de mêmes références aux différentes figures. Par souci de clarté, seuls les éléments qui sont utiles à la compréhension des modes de réalisation décrits ont été représentés et sont détaillés. En particulier, les composants internes d'un fer à repasser à vapeur sont bien connus de l'homme du métier et ne seront pas décrits en détail.The same elements have been designated by the same references in the different figures. For the sake of clarity, only the elements which are useful for understanding the embodiments described 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.

Dans la description qui suit, lorsque l'on fait référence à des qualificatifs de position absolue, tels que les termes "avant", "arrière", "haut", "bas", "gauche", "droite", etc., ou relative, tels que les termes "dessus", "dessous", "supérieur", "inférieur", etc., ou à des qualificatifs d'orientation, tels que les termes "horizontal", "vertical", etc., il est fait référence à l'orientation des figures ou à un fer à repasser dans une position normale d'utilisation. Sauf précision contraire, les expressions "approximativement", "sensiblement", et "de l'ordre de" signifient à 10 % près, de préférence à 5 % près.In the following description, when reference is made to qualifiers for absolute position, such as "front", "back", "up", "down", "left", "right", etc., or relative, such as "above", "below", "upper", "lower", etc., or to orientation qualifiers, such as "horizontal", "vertical", etc., there reference is made to the orientation of the figures or to an iron in a normal position of use. Unless otherwise specified on the contrary, the expressions "approximately", "substantially", and "of the order of" mean to the nearest 10%, preferably to the nearest 5%.

Selon un mode de réalisation, la semelle du fer à repasser à vapeur comporte au moins un décrochement destiné à créer une surface parallèle à une surface de base servant de base d'appui du fer sur le linge.According to one embodiment, the soleplate of the steam iron comprises at least one step intended to create a surface parallel to a base surface serving as a support base for the iron on the laundry.

Selon un mode de réalisation, la surface créée par le décrochement est en relief par rapport à la surface de base. La surface en relief est de préférence située dans la partie centrale de la zone de séchage du fer à repasser. La surface en relief est exempte de trous de vaporisation et est en appui permanent sur le linge en même temps que la surface de base. La surface en relief est reliée à la surface de base par une surface intermédiaire entourant la surface en relief et rejoignant la surface de base. La surface intermédiaire peut être plane ou bombée pour permettre, lors des déplacements du fer à repasser sur le linge et quelles que soient les directions de ces déplacements, de chasser la vapeur résiduelle présente dans le linge vers l'extérieur.According to one embodiment, the surface created by the step is in relief relative to the base surface. The raised surface is preferably located in the central part of the drying area of the iron. The raised surface is free from spray holes and is in permanent contact with the laundry at the same time as the base surface. The raised surface is connected to the base surface by an intermediate surface surrounding the raised surface and joining the base surface. The intermediate surface can be flat or curved to allow, during the movements of the iron on the laundry and regardless of the directions of these movements, to expel the residual vapor present in the laundry to the outside.

Selon un mode de réalisation, la surface créée par le décrochement est en dépression par rapport à la surface de base. Ceci permet de créer, sur les pourtours de la surface en dépression, des bords d'attaque améliorant la qualité et la rapidité du repassage.According to one embodiment, the surface created by the step is in depression relative to the base surface. This makes it possible to create leading edges on the edges of the depressed surface improving the quality and speed of ironing.

Les figures 1 et 2 représentent une vue de dessous et une vue partielle de côté d'une semelle 5 d'un fer à repasser. La semelle 5 comprend deux composants : le premier composant est la coiffe et le deuxième composant est le sous-ensemble chauffant, la coiffe recouvrant le sous-ensemble chauffant. Dans la suite de la description, deux modes de réalisation vont être décrits. Dans un mode de réalisation, la semelle 5 comprend une coiffe épaisse qui est désignée par la référence 10. La coiffe 10 peut être une coiffe en aluminium ayant une épaisseur par exemple comprise entre 1,5 mm et 2,5 mm. Selon un autre mode de réalisation, la semelle comprend une coiffe fine qui est désignée par la référence 11. La coiffe 11 peut être une coiffe en tôle d'acier inoxydable ou autre matière ayant une épaisseur par exemple comprise entre 0,2 mm et 0,6 mm. Le sous-ensemble chauffant, non visible sur les figures 1 et 2, est spécifique à chaque type de coiffe et est désigné par la référence 12 pour le mode de réalisation correspondant à la coiffe 10 et par la référence 13 pour le mode de réalisation correspondant à la coiffe 11. Les figures 1 et 2 sont identiques pour les coiffes 10 et 11.The Figures 1 and 2 represent 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 sub-assembly, the cap covering the heating sub-assembly. In the following 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 can be an aluminum cap having a thickness for example between 1.5 mm and 2.5 mm. According to another embodiment, the sole includes a thin cap which is designated by the reference 11. The cap 11 can 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 on the Figures 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 embodiment corresponding to the cap 11. The Figures 1 and 2 are identical for caps 10 and 11.

Les modifications apportées aux coiffes 10 ou 11 par rapport à des coiffes classiques se répartissent ainsi :

  • d'une part des modifications qui concernent la surface des coiffes 10 ou 11 en contact avec le linge qui peuvent être identiques en tous points quelle que soit la matière de la coiffe ; et
  • d'autre part des modifications qui sont en relation avec la fixation des coiffes sur leur sous-ensemble chauffant respectif, spécifique à chaque type de coiffe, en fonction de leur matériau.
The modifications made to the caps 10 or 11 compared to conventional caps are distributed as follows:
  • on the one hand, modifications which relate to the surface of the caps 10 or 11 in contact with the linen which may be identical in all respects whatever the material of the cap; and
  • on the other hand, modifications which are related to the fixing of the caps on their respective heating sub-assembly, specific to each type of cap, depending on their material.

Sur les figures 1 et 2, qui représentent la partie extérieure de la coiffe 10 ou 11 au contact du linge et qui sont communes aux deux types de coiffes 10 et 11, on distingue un décrochement correspondant à une forme convexe constituant un relief 15, également appelé portion bombée ou portion en relief, défini par rapport à une surface 16 de référence, sensiblement plane, correspondant à la plus grande partie plane de la coiffe 10 ou 11 en contact permanent avec le linge. Selon un mode de réalisation, c'est dans environ la moitié avant, de préférence le tiers avant, de la surface 16 destinée à la vaporisation, que débouchent des trous de vaporisation 20.On the Figures 1 and 2 , which represent the outer part of the cap 10 or 11 in contact with the laundry and which are common to the two types of caps 10 and 11, there is a recess corresponding to a convex shape constituting a relief 15, also called convex portion or portion in relief, defined with respect to a reference surface 16, substantially planar, corresponding to the largest planar part of the cover 10 or 11 in permanent contact with the linen. According to one embodiment, it is in approximately the front half, preferably the front third, of the surface 16 intended for vaporization, that vaporization holes 20 open.

Le volume du relief 15 est défini par une surface 17 sensiblement plane dans l'axe de la coiffe. La surface 17 est surélevée par rapport à la surface 16 et est située dans un plan parallèle à celle-ci. Une hauteur h comprise entre 0,3 mm et 2 mm sépare les deux surfaces 16 et 17. La surface 17 occupe une portion de la surface totale de la coiffe 10 ou 11 en contact avec le linge qui est comprise entre 10 % et 40 %.The volume of the relief 15 is defined by a substantially flat surface 17 in the axis of the cap. The surface 17 is raised relative to the surface 16 and is located in a plane parallel to the latter. A height h of 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 linen which is between 10% and 40%.

Une ligne L1, représentée en traits mixtes en figure 1, représente les limites de la surface 17. La ligne L1 est définie par :

  • de chaque côté, des portions de courbes c1 et c2 sensiblement parallèles à leur bord de coiffe respectif 19 pour c1 et 21 pour c2 et à une distance d1 pouvant être comprise entre 25 mm et 45 mm, par exemple égale à environ 35 mm ;
  • à l'arrière, une portion de droite p1 parallèle au talon de coiffe 22 à une distance d2 pouvant être comprise entre 25 mm et 40 mm, par exemple égal à environ 30 mm ; et
  • à l'avant, une portion circulaire r1 tangente aux courbes c1 et c2 ayant un rayon pouvant être compris entre 5 mm et 15 mm, par exemple égal à environ 8 mm.
A line L1, shown in phantom in figure 1 , represents the limits of surface 17. Line L1 is defined by:
  • on each side, portions of curves c1 and c2 substantially parallel to their respective cap edge 19 for c1 and 21 for c2 and at a distance d1 which may be between 25 mm and 45 mm, for example equal to about 35 mm;
  • at the rear, a straight portion p1 parallel to the heel cap 22 at a distance d2 which may be between 25 mm and 40 mm, for example equal to about 30 mm; and
  • at the front, a circular portion r1 tangent to the curves c1 and c2 having a radius which may be between 5 mm and 15 mm, for example equal to about 8 mm.

Le volume du relief 15 est en outre défini par une surface 18 de liaison entre la surface 16 et la surface 17.The volume of the relief 15 is further defined by a surface 18 of connection between the surface 16 and the surface 17.

Une ligne L2, en trait continu, représente les limites de la surface 18. La ligne L2 est définie par une distance d3 constante entre les lignes L1 et L2, pouvant être comprise entre 10 mm et 25 mm, par exemple égale à environ 17 mm. Ceci se traduit sur la ligne L2 par une portion de courbe c3 parallèle à la portion de courbe c1, une portion de courbe c4 parallèle à la portion de courbe c2, une portion circulaire r2 parallèle à la portion circulaire r1, une portion de droite p2 parallèle à la portion de droite p1, et par deux nouvelles portions circulaires : une portion circulaire r3 de centre o1 situé au point de croisement de la portion de courbe c1 avec la portion de droite p1, et une portion circulaire r4 de centre o2 situé au point de croisement de la portion de courbe c2 avec la portion de droite p2.A line L2, in solid line, 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 is reflected on line L2 by a portion of curve c3 parallel to the portion of curve c1, a portion of curve c4 parallel to the portion of curve c2, a circular portion r2 parallel to the circular portion r1, a portion of straight line p2 parallel to the right-hand portion p1, and by two new circular portions: a circular portion r3 of center o1 located at the point of intersection of the portion of curve c1 with the straight portion p1, and a circular portion r4 of center o2 located at point of intersection of the portion of curve c2 with the portion of line p2.

La surface 18 de jonction entre les deux lignes L1 et L2 peut être engendrée par le déplacement d'un segment de ligne droite entre les deux lignes, mais elle est préférentiellement définie par la circulation d'un rayon R de centre situé sur une perpendiculaire à la surface 17 à l'aplomb de la ligne L1, définie comme le lieu des points de tangence entre le rayon R et la surface 17. La ligne L2 est, elle, définie comme le lieu des points sécants entre le rayon R et la surface 16.The surface 18 of junction between the two lines L1 and L2 can be generated by the displacement of a straight line segment between the two lines, but it is preferably defined by the circulation of a radius R of center located on a perpendicular to surface 17 plumb with line L1, defined as the locus of the tangent points between the radius R and the surface 17. The line L2 is defined as the locus of the secant points between the radius R and the surface 16.

La figure 3 est une vue analogue à la figure 1 de la coiffe 10 ou 11 et les figures 4 et 5 sont des vues en coupe de la figure 3 respectivement selon les lignes A-A et B-B dans le cas d'une coiffe épaisse 10. En figure 3, on a représenté en traits pointillés des éléments cachés propres à la coiffe 10 et visibles sur les figures 4 et 5.The figure 3 is a view analogous to the figure 1 of cap 10 or 11 and the Figures 4 and 5 are sectional views of the figure 3 respectively along lines AA and BB in the case of a thick cap 10. In figure 3 , there are shown in dotted lines hidden elements specific to the cap 10 and visible on the Figures 4 and 5 .

Sur ces figures, on distingue, outre les modifications communes avec la coiffe 11, les modifications spécifiques suivantes de la coiffe 10 :
des formes tubulaires qui sont destinées, entre autres, à servir de rivets creux 23 pour assurer la liaison entre la partie arrière de la coiffe 10, affectée au séchage, et le sous-ensemble chauffant 12. Leur nombre, leur répartition, et leur mode d'emploi sont déterminés en fonction de l'usage choisi. Les formes tubulaires 23 sont positionnées en dehors de la surface occupée par la chambre de vaporisation.In these figures, apart from the modifications common with the cap 11, the following specific modifications to the cap 10 are distinguished:
tubular shapes which are intended, inter alia, to serve as hollow rivets 23 to ensure the connection between the rear part of the cover 10, used for drying, and the heating sub-assembly 12. Their number, their distribution, and their mode are determined according to the chosen use. The tubular forms 23 are positioned outside the surface occupied by the vaporization chamber.

Les figures 6 et 7 sont des vues en coupe de la figure 3 respectivement selon les lignes C-C et D-D dans le cas où la semelle comprend la coiffe 10 et les figures 8 et 9 sont des vues en coupe de la figure 3 respectivement selon les lignes C-C et D-D dans le cas où la semelle comprend la coiffe 11.The Figures 6 and 7 are sectional views of the figure 3 respectively along lines CC and DD in the case where the sole includes the cap 10 and the Figures 8 and 9 are sectional views of the figure 3 respectively along lines CC and DD in the case where the sole includes the cap 11.

Comme cela apparaît sur ces figures, les sous-ensembles chauffants 12 et 13, en fonderie d'aluminium surmoulant un élément chauffant tubulaire et comportant la chambre de vaporisation, sont modifiés par rapport à des sous-ensembles chauffants classiques de la façon suivante :

  • pour leur partie commune assurant le contact avec la partie intérieure des coiffes 10 et 11 : la surface de leur fonderie, initialement plate, est modifiée (figure 6), pour reproduire le relief 15 qui est positionné avec pour référence les trous de vaporisation présents sur chaque fonderie et chaque coiffe ;
  • pour la partie arrière, réservée au séchage, spécifique à la coiffe 10 en aluminium, des orifices 24 sont prévus, en face de chaque rivet creux 23 (figure 7), en plus de ceux destinés aux rivets issus de la fabrication des trous de vaporisation 20, et un chanfrein 25 est créé à l'entrée de chaque orifice 24 ;
  • pour la partie arrière, destinée au séchage, spécifique à la coiffe 11 en tôle d'acier ou autre matière, on conserve le type de forme donnée de façon classique aux bords du sous-ensemble 13 sur son pourtour (figure 8), pour assurer un sertissage.
As shown in these figures, the heating sub-assemblies 12 and 13, in aluminum foundry overmolding a tubular heating element and comprising the vaporization chamber, are modified with respect to conventional heating sub-assemblies as follows:
  • for their common part ensuring contact with the inner part of the caps 10 and 11: the surface of their foundry, initially flat, is modified ( figure 6 ), to reproduce the relief 15 which is positioned with reference to the spray holes present on each foundry and each cap;
  • for the rear part, reserved for drying, specific to the aluminum cap 10, holes 24 are provided, opposite each hollow rivet 23 ( figure 7 ), in addition to those intended for the rivets resulting from the manufacture of the vaporization holes 20, and a chamfer 25 is created at the entrance of each orifice 24;
  • for the rear part, intended for drying, specific to the cover 11 made of steel sheet or other material, the type of shape given conventionally is kept at the edges of the sub-assembly 13 around its periphery ( figure 8 ), to ensure crimping.

La figure 10 illustre un mode de réalisation d'un procédé permettant d'obtenir la structure représentée en figure 7. Dans ce mode de réalisation, les rivets creux 23 sont obtenus par extrusion filage, la ductilité de l'aluminium de la coiffe permettant d'appliquer ce procédé par lequel un poinçon mobile sous forte pression 30 vient bloquer la matière alors qu'un poinçon cylindrique 31, en s'enfonçant, la fait fluer jusqu'à former une cheminée de rivet de la hauteur voulue. A titre d'exemple, pour former les rivets creux 23 de diamètre intérieur Ø égal à 3 mm à partir d'une épaisseur de matière de 2 mm, et la pénétration du poinçon 31 étant de 1,5 mm, on peut obtenir une cheminée d'une hauteur H d'environ 4,5 mm.The figure 10 illustrates an embodiment of a method making it possible to obtain the structure represented in figure 7 . In this embodiment, the hollow rivets 23 are obtained by extrusion spinning, the ductility of the aluminum of the cap making it possible to apply this process by which a movable punch under high pressure 30 comes to block the material while a cylindrical punch 31, by sinking, causes it to creep until it forms a rivet chimney of the desired height. For example, to form the hollow rivets 23 of internal diameter Ø equal to 3 mm from a material thickness of 2 mm, and the penetration of the punch 31 being 1.5 mm, one can obtain a chimney with a height H of approximately 4.5 mm.

Selon un mode de réalisation, l'assemblage entre la coiffe 10 et le sous-ensemble 12 peut être réalisé de la manière suivante :

  • pour la partie avant, on utilise les tubes extrudés des trous de sortie vapeur 20, le sertissage étant assuré par exemple selon les techniques connues décrites dans le brevet FR2593837 ;
  • pour la partie arrière, on utilise les rivets creux 23, en procédant par écrasement limité de leur extrémité (visible sur la figure 7), la déformation engendrée, en refoulant la matière dans le chanfrein 25 prévu à cet effet assure le serrage entre les deux parties.
According to one embodiment, the assembly between the cover 10 and the sub-assembly 12 can be carried out as follows:
  • for the front part, the tubes extruded from 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, hollow rivets 23 are used, proceeding by limited crushing of their ends (visible on the figure 7 ), the deformation generated, by pushing the material into the chamfer 25 provided for this purpose ensures the clamping between the two parts.

Selon un mode de réalisation, l'assemblage entre la coiffe 11 et le sous-ensemble 13 peut être réalisé en conservant les procédés classiques, par l'utilisation des trous de vaporisation 20 et le sertissage de la coiffe 11 sur le pourtour du sous-ensemble 13.According to one embodiment, the assembly between the cap 11 and the sub-assembly 13 can be carried out while preserving the conventional methods, by the use of the holes of vaporization 20 and crimping of the cap 11 around the periphery of the sub-assembly 13.

Avant de positionner les pièces l'une contre l'autre, on prend la précaution d'enduire toutes les surfaces appelées à être en contact d'une graisse thermiquement conductrice qui viendra empêcher la formation d'une lame d'air isolante entre elles.Before positioning the parts against each other, we take the precaution of coating all the surfaces called to be in contact with a thermally conductive grease which will prevent the formation of an insulating air gap between them.

La figure 11 est une vue en coupe de la figure 3 selon la ligne F-F d'un autre mode de réalisation dans lequel des capteurs de température Ct sont installés sur la coiffe 10 à l'intérieur de certains rivets creux 23 choisis comme représentatifs de la température de la coiffe.The figure 11 is a sectional view of the figure 3 according to line FF of another embodiment in which temperature sensors Ct are installed on the cover 10 inside certain hollow rivets 23 chosen as representative of the temperature of the cover.

Comme cela apparaît en figure 9, des réserves 27 peuvent être prévues dans le sous-ensemble chauffant 13 pour permettre un accès à la coiffe 11, chacune de ces réserves 27 est couronnée d'un cône creux 28, issu de fonderie, d'épaisseur comprise par exemple entre 1 mm et 2 mm, dépassant d'une hauteur h1 comprise par exemple entre 2 mm et 6 mm côté intérieur du sous-ensemble 13.As it appears in figure 9 , reserves 27 can be provided in the heating sub-assembly 13 to allow access to the cap 11, each of these reserves 27 is crowned with a hollow cone 28, from foundry, of thickness for example between 1 mm and 2 mm, protruding by a height h1 of for example between 2 mm and 6 mm on the inside of the sub-assembly 13.

La figure 12 est une vue en coupe de la figure 3 selon la ligne F-F d'un autre mode de réalisation dans lequel des capteurs de températures Ct sont installés dans les réserves 27, aménagées en des points représentatifs de la température de semelle pour permettre un accès à la coiffe 11.The figure 12 is a sectional view of the figure 3 according to 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 allow access to the cover 11.

Le maintien en place de ces capteurs sera assuré par la déformation, soit de la tête des rivets 23 comme cela est représenté en figure 10 pour la coiffe 10, soit du sommet du cône creux 28 comme cela est représenté en figure 11 pour la coiffe 11 et par la mise en place d'un calage élastique 29 assurant l'immobilisation du capteur.The retention in place of these sensors will be ensured by the deformation, either of the head of the rivets 23 as shown in figure 10 for the cap 10, either from the top of the hollow cone 28 as shown in figure 11 for the cap 11 and by the establishment of an elastic wedging 29 ensuring the immobilization of the sensor.

Les informations collectées transmises à un calculateur et traduites peuvent permettre d'afficher, par exemple sur un écran à cristaux liquides visible d'un utilisateur, la nature du tissu pouvant être repassé.The collected information transmitted to a computer and translated can make it possible to display, for example on a liquid crystal screen visible to a user, the nature of the fabric that can be ironed.

La figure 13 est une vue en coupe de la figure 3 selon la ligne G-G illustrant le fonctionnement du fer à repasser. En cours de repassage, au niveau de la surface 17 du relief 15, la pression d'appui est concentrée car la surface de contact avec le linge 32 est réduite. L'humidité résiduelle, emprisonnée dans le linge 32 sous cette surface, soumise à la chaleur et à une pression accentuée, a la possibilité de s'évacuer latéralement, d'abord dans l'espace de hauteur h ménagé entre les surfaces 16 et 17, puis vers l'extérieur, comme cela est illustré par la flèche V en figure 13, sous l'effet du déplacement de la surface 18 qui crée une forme de coin ouvert vers les bords latéraux de la semelle. Outre un séchage global du linge de meilleure qualité, la possibilité d'obtenir des plis marqués et persistants est réelle.The figure 13 is a sectional view of the figure 3 according to line GG 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 linen 32 is reduced. The residual humidity, trapped in the linen 32 under this surface, subjected to heat and to an increased pressure, has the possibility of being discharged laterally, first in the space of height h formed between the surfaces 16 and 17 , then outwards, 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. Besides an overall drying of the best quality linen, the possibility of obtaining marked and persistent folds is real.

La surface extérieure de chacune des coiffes reste compatible avec l'application des revêtements connus, mais on peut en améliorer la conductivité thermique par une projection flash de nitrure de bore, par exemple, en surface de la barbotine d'émail avant sa cuisson.The outer surface of each cap remains compatible with the application of known coatings, but the thermal conductivity can be improved by a flash projection of boron nitride, for example, on the surface of the enamel slip before baking.

Il est, en outre, souhaitable d'obtenir la disparition des plis du tissu lors de son repassage.It is, moreover, desirable to obtain the disappearance of the folds of the fabric during its ironing.

Dans ce but, de nombreuses recherches furent menées qui aboutirent à des solutions, toutes orientées vers l'amélioration des relations de surface fer/linge : meilleure résistance à l'usure, meilleure glisse, meilleure évacuation d'humidité résiduelle ou encore meilleure transmission thermique.To this end, a great deal of research was carried out which led to solutions, all of which were aimed at improving iron / linen surface relationships: better resistance to wear, better sliding, better evacuation of residual moisture or even better thermal transmission. .

Le rendement en repassage pouvant se définir comme le meilleur compromis entre les facteurs : vitesse / qualité / moindre pénibilité / moindre usure du linge, il était remarquable d'observer que la plupart de ces actions avaient pour seul but l'optimisation des relations suscitées.Since ironing performance can be defined as the best compromise between factors: speed / quality / less arduous work / less wear and tear on the laundry, it was remarkable to observe that most of these actions had the sole aim of optimizing the relationships created.

C'était négliger l'importance de la première action auxquelles les fibres d'un tissu sont soumises en cours de repassage, qui est une action mécanique de mise en tension du tissu par l'intermédiaire du bord de la semelle, phénomène observable, car, tout déplacement du fer engendre l'apparition d'une ondulation mobile, parallèle à ce bord. Avec les semelles à coiffes rapportées, cette traction sur les fibres est diminuée à cause, d'une part, du rayon de courbure de leur bord dû à leur fabrication, d'autre part à la diminution de leur coefficient de frottement sur le linge. Les améliorations apportées dans ces domaines ont, de fait, nuit à la rapidité de la mise en forme des fibres car à conditions d'humidification équivalentes, obtenir des fibres droites en tendant le tissu est plus efficace et plus rapide que de le faire en appuyant sur elles pour les redresser. Il y a donc là une possibilité d'amélioration de la vitesse de repassage.It was to neglect 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 displacement of the iron generates the appearance of a mobile undulation, parallel to this edge. With the insoles with added caps, this traction on the fibers is reduced due, on the one hand, to the radius of curvature of their edge due to their manufacture, on the other hand to the reduction in their coefficient of friction on the linen. The improvements made in these areas have, in fact, adversely affected the speed of the shaping of the fibers since, at equivalent humidification conditions, obtaining straight fibers by stretching the fabric is more efficient and faster than doing so by pressing on them to straighten them. There is therefore a possibility of improving the ironing speed.

Un objet d'un mode de réalisation est d'augmenter sensiblement le rendement en repassage en améliorant la tension des fibres dès le premier mouvement de la semelle sur le linge.An object of an embodiment is to significantly increase the ironing yield by improving the tension of the fibers from the first movement of the sole on the laundry.

La figure 14 est une vue de dessous d'une semelle 105 d'un fer à repasser. Comme cela a été décrit précédemment, la semelle 105 comprend deux composants : le premier composant est la coiffe et le deuxième composant est le sous-ensemble chauffant, la coiffe recouvrant le sous-ensemble chauffant. Dans la suite de la description, deux modes de réalisation vont être décrits. Dans un mode de réalisation, la semelle 105 comprend une coiffe épaisse qui est désignée par la référence 110. La coiffe 110 peut être une coiffe en aluminium ayant une épaisseur par exemple comprise entre 1,5 mm et 2,5 mm. Selon un autre mode de réalisation, la semelle comprend une coiffe fine qui est désignée par la référence 111. La coiffe 111 peut être une coiffe en tôle d'acier inoxydable ou autre matière ayant une épaisseur par exemple comprise entre 0,2 mm et 0,6 mm. Le sous-ensemble chauffant, non visible sur la figure 14, est spécifique à chaque type de coiffe et est désigné par la référence 112 pour le mode de réalisation correspondant à la coiffe 110 et par la référence 113 pour le mode de réalisation correspondant à la coiffe 111. La figure 14 est la même pour les coiffes 110 et 111.The 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 sub-assembly, the cap covering the heating sub-assembly. In the following description, two embodiments will be described. In one embodiment, the sole 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 includes a thin cap which is designated by the reference 111. The cap 111 can 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 on the figure 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 the reference 113 for the embodiment corresponding to the cap 111. The figure 14 is the same for caps 110 and 111.

La figure 15 est une vue en coupe de la coiffe 110 ou 111 selon la ligne a-a. La figure 16 est une vue agrandie d'une partie de la figure 15 dans le cas d'une coiffe épaisse 110 et la figure 17 est une vue agrandie d'une partie de la figure 16 dans le cas d'une coiffe épaisse 110.The figure 15 is a sectional view of the cap 110 or 111 along the line aa. The figure 16 is an enlarged view of a part of the figure 15 in the case of a thick cap 110 and the figure 17 is an enlarged view of part of the figure 16 in the case of a thick cap 110.

Comme cela apparaît sur les figures 14 à 16, la coiffe 110 en aluminium et la coiffe 111 en tôle d'acier ou autre matière objets de l'invention comportent :

  • une surface 113 de référence, par exemple sensiblement plane, correspondant à la partie de la coiffe en contact permanent avec le linge ;
  • une surface 114 et une surface 115, par exemple sensiblement planes, sensiblement parallèles entre elles et au bord de la coiffe, de largeurs m comprises entre 0,7 mm et 1,5 mm, les surfaces 114 et 115 faisant le tour de la coiffe 110 ou 111 ;
  • une surface 116, par exemple sensiblement plane, dont les limites L sont sensiblement parallèles entre elles et au bord de la coiffe. L'axe de symétrie de cette surface 116, de largeur par exemple comprise entre 7 mm et 16 mm est situé à une distance par exemple comprise entre 12 mm et 24 mm du bord de la coiffe. Des trous de vaporisation 120 débouchent sur cette surface 116 et délimitent sa longueur qui sera adaptée en fonction de leur nombre ; et
  • une surface 117, par exemple sensiblement plane, sensiblement parallèle aux limites L de la surface 116 de largeur par exemple comprise entre 0,7 mm et 1,5 mm.
As it appears on the figures 14 to 16 , the cap 110 of aluminum and the cap 111 of sheet steel or other material which is the subject of the invention comprises:
  • a reference surface 113, for example substantially planar, corresponding to the part of the cap in permanent contact with the linen;
  • a surface 114 and a surface 115, for example substantially planar, substantially parallel to each other and to the edge of the cap, of widths m comprised between 0.7 mm and 1.5 mm, the surfaces 114 and 115 going around the cap 110 or 111;
  • a surface 116, for example substantially planar, the limits L of which 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 onto this surface 116 and define its length which will be adapted according to their number; and
  • a surface 117, for example substantially planar, substantially parallel to the limits L of the surface 116 of width for example between 0.7 mm and 1.5 mm.

Sur la figure 14, on a représenté deux agencements possibles de la surface 116. En partie droite de la figure 14, on a représenté une surface 116 qui s'étend de l'avant de la coiffe jusqu'au talon de coiffe tandis qu'en partie gauche de la figure 14, la surface 116 s'étend de l'avant de la coiffe jusqu'à la moitié de la coiffe. De préférence, la surface 16 est répartie de la même façon le long de deux bords latéraux de la coiffe.On the figure 14 , two possible arrangements of the surface 116 have been shown. In the right part of the figure 14 , there is shown a surface 116 which extends from the front of the cap to the cap heel while in the left part of the 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.

Les surfaces 114, 115, 116 et 117 représentent les modifications de base de la coiffe 110 et 111, mais il peut être ajouté, selon besoin, d'autres surfaces de formes différentes mais de caractérisations semblables comme par exemple les surfaces 118 et 119.The surfaces 114, 115, 116 and 117 represent the basic modifications of the cap 110 and 111, but it can be added, if necessary, other surfaces of different shapes but of similar characterizations such as for example surfaces 118 and 119.

Les surfaces 114 à 119 sont en dépression par rapport à la surface de référence 113. Elles sont obtenues en créant des décrochements (visibles notamment en figure 17), de hauteur h par exemple comprise entre 0,15 mm et 0,4 mm. Chaque hauteur h de décrochement engendre un bord d'attaque 121 et 122 pour ceux au contact de la surface 113 de référence, un bord d'attaque 123 pour celui au contact de la surface 114, un bord d'attaque 124 pour celui à l'intersection entre le bord de la coiffe et la surface 115, ainsi qu'un bord d'attaque 125 pour celui au contact de la surface 117. En conséquence, les surfaces 114 et 117 sont sur un même plan, ainsi que les surfaces 115 et 116.The surfaces 114 to 119 are in depression relative to the reference surface 113. They are obtained by creating notches (visible in particular in figure 17 ), of height h for example between 0.15 mm and 0.4 mm. Each drop height h generates a leading edge 121 and 122 for those in contact with the reference surface 113, a leading edge 123 for that in contact with the surface 114, a leading edge 124 for the one at l intersection between the edge of the cap and the surface 115, as well as a leading edge 125 for that 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.

Selon un mode de réalisation, pour éviter un effet d'usure du linge, chaque bord d'attaque a un même rayon r, par exemple compris entre 0,2 mm et 0,3 mm, qui est par exemple élaboré par matriçage et/ou semi-découpage pour garantir sa régularité dimensionnelle et un état de surface propre et sans bavure.According to one embodiment, to avoid a wear effect of the linen, each leading edge has the same radius r, for example between 0.2 mm and 0.3 mm, which is for example produced by stamping and / or semi-cutting to guarantee its dimensional regularity and a clean and burr-free surface finish.

Pour la fabrication des coiffes 110 et 111, la qualité et les garanties dimensionnelles des bords d'attaque sont obtenues en mettant en oeuvre des procédés différents selon la matière des coiffes.For the manufacture of caps 110 and 111, the quality and dimensional guarantees of the leading edges are obtained by implementing different methods depending on the material of the caps.

La figure 18 illustre un mode de réalisation d'un procédé de fabrication de la coiffe 110. Pour l'élaboration des surfaces 114, 115, 116 et 117 ainsi que, si besoin est des surfaces 118 et 119, on procède par matriçage, en jouant sur la ductilité de l'aluminium pour déplacer la matière de sa forme initiale, indiquée par la ligne en traits pointillés Fi, vers sa forme définitive Fd. La coiffe est introduite dans l'outil après l'opération d'emboutissage relevage des bords, puis positionnée sur le plan d'accostage Pa des matrices 125 et 126 comportant, en creux, les formes des bords d'attaques 121, 122, 123, 124 et 125 de rayon r. La coiffe est maintenue plaquée contre le plan Pa par un serre flan 127. On fait alors pénétrer un poinçon 128 dont la forme et la profondeur de pénétration ont été étudiées pour déplacer la quantité d'aluminium juste nécessaire pour que tous les espaces vides soient remplis.The figure 18 illustrates an embodiment of a method of manufacturing the cap 110. For the development of the surfaces 114, 115, 116 and 117 as well as, if necessary is the surfaces 118 and 119, one proceeds by stamping, by playing on the aluminum ductility to move the material from its initial shape, indicated by the dashed line Fi, to its final shape Fd. The cap is introduced into the tool after the drawing operation, raising of the edges, then positioned on the docking plane Pa of the dies 125 and 126 comprising, in hollow, the shapes of the leading edges 121, 122, 123 , 124 and 125 of radius r. The cap is held pressed against the plane Pa by a blank holder 127. A punch 128 is then made to penetrate, the shape and depth of penetration have been studied to move the quantity of aluminum just necessary so that all the empty spaces are filled.

La figure 19 illustre un mode de réalisation d'un procédé de fabrication de la coiffe 111. On procède par semi-cisaillage. La coiffe une fois positionnée et maintenue en place par un serre flan 129 sur les matrices 130 et 131, on descend le poinçon de découpe 132 vers ces matrices, dans lesquelles on le fait pénétrer de la hauteur h.The figure 19 illustrates an embodiment of a method for manufacturing the cap 111. This is done 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 towards these dies, into which it is made to penetrate from height h.

La figure 20 est une vue de détail de la figure 19. Le rayon r des bords d'attaque ba est obtenu en jouant sur le jeu j entre le poinçon de découpe 132 et les matrices 130 et 131. C'est ce jeu j qui permet de régler le rayon de sortie de découpe, jusqu'à obtenir le rayon r souhaité.The figure 20 is a detail view of the figure 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 clearance j which makes it possible to adjust the cutting outlet radius, up to get the desired radius r.

Selon un mode de réalisation, le sous-ensemble chauffant 112, constitué d'une fonderie d'aluminium surmoulant un élément chauffant tubulaire et comportant la chambre de vaporisation, est modifié de la façon suivante qui vaut aussi bien pour les coiffes en aluminium 110 que pour les coiffes 111 en acier ou autre matière.According to one embodiment, the heating sub-assembly 112, consisting of an aluminum foundry overmolding a tubular heating element and comprising the vaporization chamber, is modified in the following manner which is valid for both the aluminum caps 110 and for 111 caps in steel or other material.

La fabrication des dépressions des surfaces 116 et 117 engendre à l'inverse et en relief par rapport à la face interne de la coiffe des saillies 133 et 134, comme cela est visible sur la figure 16. La fonderie du sous-ensemble 112 sera modifiée en conséquence pour loger les saillies 133 et 134 au plus juste.The manufacturing of the depressions on the surfaces 116 and 117 generates inversely and in relief with respect to the internal face of the cap of the projections 133 and 134, as is visible on the figure 16 . The foundry of the sub-assembly 112 will be modified accordingly to accommodate the projections 133 and 134 as closely as possible.

Un mode de réalisation d'un procédé d'assemblage entre les coiffes 110 ou 111 et le sous-ensemble chauffant 112 va maintenant être décrit.An embodiment of an assembly method between the caps 110 or 111 and the heating sub-assembly 112 will now be described.

La figure 21 est une vue en coupe de la semelle représentée en figure 14 selon la ligne d-d. Pour les coiffes 110 et si l'option de créer des trous vapeur jusqu'à l'arrière de la semelle a été choisie comme cela est représenté en figure 14 pour la partie gauche de la semelle 105, on utilise la technique de sertissage à l'aide des trous vapeur décrite dans le brevet FR2593837 .The figure 21 is a sectional view of the sole shown in figure 14 along line dd. For 110 caps and if the option of creating steam holes up to the back of the soleplate has been chosen as shown in figure 14 for the left part of the sole 105, the crimping technique using the steam holes described in the patent is used FR2593837 .

La figure 22 illustre un mode de réalisation d'un procédé d'assemblage entre la coiffe 110 et le sous-ensemble chauffant 112.The figure 22 illustrates an embodiment of an assembly process between the cap 110 and the heating sub-assembly 112.

Si l'option choisie est celle d'une semelle à zones de vaporisation et de séchage séparées, notamment telle que décrit selon le brevet US6189245 , on procède par sertissage à l'aide des trous vapeur dans la zone de vaporisation, et, pour la zone de séchage en partie arrière comme cela est représenté en figure 14 pour la partie droite de la semelle 105, dépourvue de moyen de fixation, on crée localement des encochages de largeur R, par exemple comprise entre 2 mm et 4 mm en enfonçant une lame 135, de largeur correspondante, pour former un copeau 136 d'épaisseur supérieure à une demi épaisseur de la tôle de coiffe, celui-ci en se rabattant sur le bord de l'ensemble chauffant 112 assurera localement le serrage entre les deux parties. Il y aura autant de points de sertissage, selon cette méthode, que nécessaire pour assurer un contact parfait entre la surface interne de la coiffe 110 ou 111 et celle du sous-ensemble chauffant 112.If the option chosen is that of a soleplate with separate spraying and drying zones, in particular as described according to patent US6189245 , we proceed by crimping using steam holes in the vaporization zone, and, for the drying zone in the rear part as shown in figure 14 for the right part of the sole 105, devoid of fastening means, notches of width R are created locally, for example between 2 mm and 4 mm by driving in a blade 135, of corresponding width, to form a chip 136 of thickness greater than half the thickness of the cover plate, this being folded over the edge of the heating assembly 112 will locally tighten between the two parts. There will be as many crimp points, according to this method, as necessary to ensure perfect contact between the internal surface of the cap 110 or 111 and that of the heating sub-assembly 112.

Pour les coiffes 111, quelle que soit l'option choisie, on conserve les méthodes de fixation connues actuelles.For the caps 111, whatever the option chosen, the current known fixing methods are retained.

Avant de positionner les pièces l'une contre l'autre, on enduira toutes les surfaces appelées à être en contact d'une graisse thermiquement conductrice qui viendra empêcher la formation d'une lame d'air isolante entre elles.Before positioning the parts against each other, we will coat all surfaces called to be in contact with a thermally conductive grease which will prevent the formation of an insulating air gap between them.

La figure 23 est une vue en coupe de la figure 14 selon la ligne c-c illustrant le fonctionnement du fer à repasser. En cours de repassage, au niveau du tissu 137 à repasser, la répétition de la traction (zone T) exercée par le mouvement du fer (flèche D) sur le linge par la pluralité de bords d'attaque améliore la rapidité de sa mise à plat ou de la formation de plis.The figure 23 is a sectional view of the figure 14 according to line cc illustrating the functioning 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 linen by the plurality of leading edges improves the speed of its setting. flat or fold formation.

Divers modes de réalisation avec diverses variantes ont été décrits ci-dessus. On note que l'homme de l'art peut combiner divers éléments de ces divers modes de réalisation et variantes sans faire preuve d'activité inventive. A titre d'exemple, les surfaces 114 et 115 de la semelle 105 décrite en relation avec les figures 14 à 23 peuvent être mises en oeuvre avec la semelle 5 décrite en relation avec les figures 1 à 13.Various embodiments with various variants have been described above.
