Description

La présente invention se rapporte à un fer à repasser à vapeur comprenant un corps chauffant comprenant une chambre de vaporisation et une surface de repassage en relation thermique avec le corps chauffant, la surface de repassage étant destinée à venir en contact avec le linge à repasser et étant avantageusement munie de trous de sortie de vapeur, et se rapporte plus particulièrement à un fer à repasser dans lequel la chaleur produite par le corps chauffant est transmise à la surface de repassage par conduction au travers d'au moins deux éléments du fer à repasser rapportés l'un contre l'autre lors de l'assemblage du fer à repasser.The present invention relates to a steam iron comprising a heating body comprising a vaporization chamber and an ironing surface in thermal relationship with the heating body, the ironing surface being intended to come into contact with the linen to be ironed and being advantageously provided with steam outlet holes, and relates more particularly to an iron in which the heat produced by the heating body is transmitted to the ironing surface by conduction through at least two elements of the iron placed against each other when assembling the iron.

Il est connu, de la demande de brevet FR 2 798 403 déposée par la demanderesse, un fer à repasser à vapeur comprenant une semelle comportant un corps chauffant comprenant une chambre de vaporisation pour la production de vapeur et une surface de repassage en relation thermique avec le corps chauffant, la surface de repassage étant destinée à venir en contact avec le linge à repasser et étant munie de trous de sortie de vapeur. Dans ce document, la surface de repassage est portée par une coiffe qui est rapportée sur le corps chauffant, la chaleur produite par le corps chauffant étant transmise à la surface de repassage par conduction au travers du corps chauffant puis au travers d'une coiffe, cette dernière étant au contact du corps chauffant au niveau de zones de contact constituées par des parois de canaux de distribution et par des plots de transfert thermique.It is known, from the patent application FR 2 798 403 filed by the applicant, a steam iron comprising a soleplate comprising a heating body comprising a vaporization chamber for the production of steam and an ironing surface in thermal relationship with the heating body, the ironing surface being intended to come into contact with the laundry to be ironed and being provided with steam outlet holes. In this document, the ironing surface is carried by a cover which is attached to the heating body, the heat produced by the heating body being transmitted to the ironing surface by conduction through the heating body then through a cover, the latter being in contact with the heating body at the level of contact zones constituted by the walls of distribution channels and by heat transfer studs.

Une telle construction de fer à repasser permet de limiter le flux thermique s'établissant vers la surface de repassage afin d'avoir une température du corps chauffant au voisinage de la chambre de vaporisation qui soit suffisante pour assurer la vaporisation de l'eau même quand la surface de repassage est à une température minimale autorisant le repassage de tissus délicats.Such an iron construction makes it possible to limit the thermal flow established towards the ironing surface in order to have a temperature of the heating body in the vicinity of the vaporization chamber which is sufficient to ensure the vaporization of the water even when the ironing surface is at a minimum temperature allowing the ironing of delicate fabrics.

Cependant, une telle construction présente l'inconvénient de faire appel à des plots portés par la fonderie qui sont relativement encombrants et qui assurent localement une forte conduction thermique. De tels plots génèrent donc des contraintes importantes pour le dessin de la fonderie et peuvent provoquer des points chauds importants sur la surface de repassage.However, such a construction has the disadvantage of using studs carried by the foundry which are relatively bulky and which ensure locally strong thermal conduction. Such studs therefore generate significant stresses for the design of the foundry and can cause significant hot spots on the ironing surface.

Aussi, un but de la présente invention est de proposer un fer à repasser à vapeur qui remédie à ces inconvénients et qui possède une structure qui soit simple et économique à réaliser. Les documents FR1424320 A , EP0380896 A1 et EP1772551 A1 divulguent des fers à repasser à vapeur.Also, an object of the present invention is to provide a steam iron which overcomes these drawbacks and which has a structure which is simple and economical to produce. The documents FR1424320A , EP0380896 A1 and EP1772551 A1 disclose steam irons.

A cet effet, l'invention a pour objet un fer à repasser à vapeur comprenant un corps chauffant comprenant une chambre de vaporisation et une surface de repassage en relation thermique avec le corps chauffant, la surface de repassage étant destinée à venir en contact avec le linge à repasser et étant avantageusement munie de trous de sortie de vapeur, la chaleur produite par le corps chauffant étant transmise à la surface de repassage par conduction au travers d'au moins deux éléments du fer à repasser rapportés l'un contre l'autre, caractérisé en ce que les deux éléments sont au contact direct l'un de l'autre au niveau d'au moins un point de contact présentant une surface de contact inférieure à 2 mm2 et de préférence inférieure à 1 mm2.To this end, the subject of the invention is a steam iron comprising a heating body comprising a vaporization chamber and an ironing surface in thermal relationship with the heating body, the ironing surface being intended to come into contact with the linen to be ironed and being advantageously provided with steam outlet holes, the heat produced by the heating body being transmitted to the ironing surface by conduction through at least two elements of the iron placed one against the other , characterized in that the two elements are in direct contact with each other at at least one point of contact having a contact surface of less than 2 mm 2 and preferably less than 1 mm 2 .

Par deux éléments du fer à repasser rapportés l'un contre l'autre on entend deux éléments constitutifs du fer à repasser qui ont été fabriqués indépendamment l'un de l'autre puis rapportés l'un contre l'autre lors de l'assemblage du fer à repasser. Une telle caractéristique permet d'établir localement un point de contact diffusant peu d'énergie par conduction thermique tout en assurant un lien mécanique entre les deux éléments.By two elements of the iron placed against each other is meant two constituent elements of the iron which have been manufactured independently of each other and then placed against each other during assembly iron. Such a characteristic makes it possible to locally establish a point of contact diffusing little energy by thermal conduction while ensuring a mechanical link between the two elements.

Selon une autre caractéristique de l'invention, les deux éléments sont au contact direct l'un de l'autre au niveau de plusieurs points de contact, tous les points de contact présentant une surface de contact inférieure à 2 mm2 et de préférence inférieure à 1 mm2.According to another characteristic of the invention, the two elements are in direct contact with each other at several contact points, all the contact points having a contact surface of less than 2 mm 2 and preferably less at 1 mm 2 .

Une telle caractéristique permet de répartir la diffusion thermique par conduction entre les deux éléments au niveau de plusieurs points de contact à faible diffusivité thermique pour une répartition plus homogène de la chaleur et une meilleur tenue mécanique entre les deux éléments.Such a characteristic makes it possible to distribute the thermal diffusion by conduction between the two elements at several contact points with low thermal diffusivity for a more homogeneous distribution of the heat and better mechanical strength between the two elements.

Selon encore une autre caractéristique de l'invention, le fer à repasser comporte au moins 3 points de contact et de préférence entre 10 et 30 points de contact entre les deux éléments.According to yet another characteristic of the invention, the iron comprises at least 3 contact points and preferably between 10 and 30 contact points between the two elements.

Selon une autre caractéristique de l'invention, les points de contact sont situés à l'extrémité de protubérances faisant saillies sur une surface d'au moins l'un des éléments.According to another characteristic of the invention, the contact points are located at the end of protuberances projecting from a surface of at least one of the elements.

Selon une autre caractéristique de l'invention, les protubérances sont obtenues par un procédé d'emboutissage.According to another characteristic of the invention, the protrusions are obtained by a stamping process.

Une telle caractéristique permet de profiter de l'espace ménagé entre les deux éléments pour faire circuler la vapeur et la répartir sur toute la surface des éléments.Such a feature makes it possible to take advantage of the space provided between the two elements to circulate the steam and distribute it over the entire surface of the elements.

Selon encore une autre caractéristique de l'invention, un joint d'étanchéité est disposé entre les deux éléments à la périphérie de la chambre de distribution.According to yet another characteristic of the invention, a seal is arranged between the two elements at the periphery of the distribution chamber.

Une telle caractéristique permet d'éviter que la vapeur ne s'échappe à la périphérie des deux éléments.Such a characteristic makes it possible to prevent the steam from escaping at the periphery of the two elements.

Selon une autre caractéristique de l'invention, la semelle comporte une plaque qui est rapportée contre le corps chauffant, le ou lesdits points de contact étant situés à l'interface entre le corps chauffant et la plaque.According to another characteristic of the invention, the sole comprises a plate which is fitted against the heating body, the said point(s) of contact being located at the interface between the heating body and the plate.

Ainsi, le corps chauffant et la plaque constituent les deux éléments du fer à repasser qui sont rapportés l'un contre l'autre et présentent des points de contact de faible superficie.Thus, the heating body and the plate constitute the two elements of the iron which are placed one against the other and have points of contact of small surface area.

Selon une autre caractéristique de l'invention, les points de contacts sont répartis le long de la périphérie de la surface de repassage.According to another characteristic of the invention, the contact points are distributed along the periphery of the ironing surface.

Selon une autre caractéristique de l'invention, la plaque est en aluminium.According to another characteristic of the invention, the plate is made of aluminum.

Une telle caractéristique permet d'assurer une forte conduction thermique dans l'épaisseur de la plaque.Such a characteristic makes it possible to ensure strong thermal conduction in the thickness of the plate.

Selon une autre caractéristique de l'invention, le fer à repasser comporte une coiffe, avantageusement en acier inox, qui est rapportée sur la plaque, la surface de repassage étant supportée par la coiffe.According to another characteristic of the invention, the iron comprises a cap, advantageously made of stainless steel, which is attached to the plate, the ironing surface being supported by the cap.

Une telle caractéristique permet de combiner à la fois une bonne homogénéité de température au niveau de la surface de repassage grâce à la bonne diffusion thermique s'effectuant au travers de la plaque en aluminium et une bonne résistance aux rayures de la surface de repassage lorsque la coiffe est réalisée dans un matériau résistant aux rayures tel que l'inox.Such a characteristic makes it possible to combine both good temperature homogeneity at the level of the ironing surface thanks to the good thermal diffusion taking place through the aluminum plate and good scratch resistance of the ironing surface when the cap is made of a scratch-resistant material such as stainless steel.

Selon une autre caractéristique de l'invention, la plaque est fixée sur le corps chauffant au moyen de vis, la coiffe étant fixée sur la plaque par rabat des bords de la coiffe sur les bords de la plaque.According to another characteristic of the invention, the plate is fixed to the heating body by means of screws, the cover being fixed to the plate by flapping the edges of the cover over the edges of the plate.

Selon une autre caractéristique de l'invention, le corps chauffant est une fonderie renfermant une résistance électrique.According to another characteristic of the invention, the heating body is a foundry containing an electrical resistor.

Selon une autre caractéristique de l'invention, la résistance électrique est le seul élément chauffant du fer à repasser.According to another characteristic of the invention, the electric resistor is the only heating element of the iron.

La figure 1 représente un fer à repasser comportant un boîtier 1 en matière plastique comportant une poignée et un talon sur lequel le fer peut reposer verticalement. Le boitier 1 renferme, de manière connue en soi, un réservoir muni d'un orifice de remplissage 10 et comporte un cordon 11 pour l'alimentation électrique du fer à l'aide d'un réseau domestique en 220V.The figure 1 represents an iron comprising a casing 1 made of plastic material comprising a handle and a heel on which the iron can rest vertically. The box 1 contains, in a manner known per se, a reservoir provided with a filling orifice 10 and comprises a cord 11 for the electrical supply of the iron using a 220V domestic network.

Conformément aux figures 2 à 6, le fer à repasser comporte une semelle 2 comprenant un corps chauffant 3 en aluminium moulé incluant une résistance électrique 30 tubulaire dont la puissance peut atteindre 2300 W et qui est le seul élément chauffant du fer à repasser. L'alimentation de cette résistance électrique 30 est régulée au moyen d'un thermostat, non représenté sur les figures, venant se fixer sur un logement 31 ménagé sur une face supérieure du corps chauffant 3, le thermostat étant avantageusement réglé autour d'une température de consigne de 165°C non modifiable par l'utilisateur.In accordance with figures 2 to 6 , the iron comprises a soleplate 2 comprising a heating body 3 made of molded aluminum including a tubular electric resistor 30 whose power can reach 2300 W and which is the only heating element of the iron. The power supply to this electrical resistor 30 is regulated by means of a thermostat, not shown in the figures, which is fixed on a housing 31 made on an upper face of the heating body 3, the thermostat being advantageously set around a temperature set point of 165°C not modifiable by the user.

Comme on peut le voir sur les figures 4 et 6, la face supérieure du corps chauffant 3 comprend des parois en saillie qui définissent une chambre de vaporisation 32 alimentée en eau du réservoir par une pompe ou un boisseau goutte-à-goutte, non représentés sur les figures, et des canaux 33 de distribution de vapeur s'étendant le long de la périphérie de la chambre de vaporisation 32, ces canaux 33 se rejoignant au niveau de l'extrémité avant du corps chauffant 3.As can be seen on the figure 4 and 6 , the upper face of the heating body 3 comprises projecting walls which define a vaporization chamber 32 supplied with water from the reservoir by a pump or a drip valve, not shown in the figures, and channels 33 for distributing vapor extending along the periphery of the vaporization chamber 32, these channels 33 meeting at the level of the front end of the heating body 3.

Les canaux 33 comportent des passages 33A traversant le corps chauffant 3 et débouchant dans une cavité ménagée sur la face inférieure du corps chauffant 3 formant une chambre de distribution 34 de vapeur.Channels 33 include passages 33A passing through heating body 3 and opening into a cavity provided on the underside of heating body 3 forming a steam distribution chamber 34 .

La semelle 2 comporte, sous le corps chauffant 3, une plaque 4 intermédiaire, avantageusement en aluminium, dont la face supérieure vient au contact du corps chauffant 3 et définie une paroi de délimitation de la chambre de distribution 34 de vapeur.The sole 2 comprises, under the heating body 3, an intermediate plate 4, advantageously made of aluminum, the upper face of which comes into contact with the heating body 3 and defines a wall for delimiting the distribution chamber 34 of steam.

La semelle 2 comporte également une coiffe 5 métallique, avantageusement en acier inoxydable, qui est rapportée contre la face inférieure de la plaque 4, la coiffe 5 métallique venant au contact direct de la plaque 4 et étant avantageusement fixée sur cette dernière en repliant le bord périphérique de la coiffe 5 autour du bord périphérique de la plaque 4.The sole 2 also comprises a metal cap 5, advantageously made of stainless steel, which is fitted against the underside of the plate 4, the metal cap 5 coming into direct contact with the plate 4 and being advantageously fixed to the latter by folding the edge peripheral of the cap 5 around the peripheral edge of the plate 4.

La coiffe 5 comprend, de manière connue en soi, une surface inférieure plane qui définie une surface de repassage 52 destinée à venir en contact avec le linge à repasser. Cette surface de repassage 52 est avantageusement munie de plus de deux cents trous 50 de sortie de vapeur présentant une section de passage inférieure à 4 mm2, ainsi que cela est décrit plus en détails dans la demande de brevet EP 1 772 551 déposée par la demanderesse. Les trous 50 de sortie de vapeur sont avantageusement répartis selon un premier et un second réseau de trous 50 de sortie de vapeur séparés l'un de l'autre par une zone médiane 51 démunie de trous de sortie de vapeur.The cap 5 comprises, in a manner known per se, a flat lower surface which defines an ironing surface 52 intended to come into contact with the laundry to be ironed. This ironing surface 52 is advantageously provided with more than two hundred steam outlet holes 50 having a passage section of less than 4 mm 2 , as described in more detail in the patent application EP 1 772 551 filed by the plaintiff. The steam outlet holes 50 are advantageously distributed according to a first and a second network of steam outlet holes 50 separated from each other by a middle zone 51 devoid of steam outlet holes.

Comme on peut le voir sur les figures 3A, 4 et 5, la plaque 4 comporte plusieurs bossages 40 en relief dont les extrémités supérieures forment des points de contact 40A entre la plaque 4 et le corps chauffant 3, le corps chauffant 3 comportant, en regard de chacun de ces bossages, une butée 35 munie d'une surface plane contre laquelle vient s'appuyer le bossage 40 lorsque la plaque 4 est assemblée contre le corps chauffant 3.As can be seen on the figure 3A , 4 and 5 , the plate 4 comprises several bosses 40 in relief, the upper ends of which form points of contact 40A between the plate 4 and the heating body 3, the heating body 3 comprising, opposite each of these bosses, a stop 35 provided with a flat surface against which the boss 40 comes to rest when the plate 4 is assembled against the heating body 3.

Ces bossages 40 sont préférentiellement réalisés par un procédé d'emboutissage de la plaque 4 et présentent une surface supérieure sensiblement sphérique.These bosses 40 are preferably produced by a process of stamping the plate 4 and have a substantially spherical upper surface.

Chaque bossage 40 fait avantageusement saillie sur une hauteur de l'ordre de 0,6 mm par rapport à la surface supérieure de la plaque 4. Un joint en silicone 6, illustré sur les figures 5 et 7, est interposé entre la plaque 4 et le corps chauffant 3 sur tout le pourtour de la chambre de distribution 34 pour assurer l'étanchéité à la vapeur, ce joint silicone 6 présentant également une épaisseur de 0,6 mm.Each boss 40 advantageously protrudes over a height of the order of 0.6 mm relative to the upper surface of the plate 4. A silicone seal 6, illustrated on the figure 5 and 7 , is interposed between the plate 4 and the heating body 3 over the entire periphery of the distribution chamber 34 to ensure the seal against steam, this silicone gasket 6 also having a thickness of 0.6 mm.

L'extrémité supérieure de chaque bossage 40 forme un point de contact 40A qui présente une surface de contact inférieure à 2 mm2 et de préférence inférieure à 1 mm2. Dans l'exemple particulier de réalisation illustré sur les figures, la plaque 4 présente une épaisseur de l'ordre de 2 mm et comporte dixsept bossages 40 répartis sur la périphérie de la plaque 4, les bossages 40 présentant une surface de contact avec les butées 35 constituée par une surface circulaire d'un diamètre de l'ordre de 1 mm.The upper end of each boss 40 forms a contact point 40A which has a contact surface of less than 2 mm 2 and preferably less than 1 mm 2 . In the particular embodiment illustrated in the figures, the plate 4 has a thickness of the order of 2 mm and comprises seventeen bosses 40 distributed over the periphery of the plate 4, the bosses 40 having a contact surface with the stops 35 consisting of a circular surface with a diameter of the order of 1 mm.

De manière préférentielle, les surfaces de contact des bossages 40 sont les seules zones où la plaque 4 est directement en contact avec le corps chauffant 3 de sorte que le transfert thermique par conduction entre le corps chauffant 3 et la plaque 4 s'effectue seulement par ces bossages 40.Preferably, the contact surfaces of the bosses 40 are the only zones where the plate 4 is directly in contact with the heating body 3 so that the heat transfer by conduction between the heating body 3 and the plate 4 takes place only by these bosses 40.

De manière avantageuse, la plaque 4 est fixée contre le corps chauffant 3 par trois vis 7, visibles sur la figure 5, une des vis 7 étant disposée à proximité d'une pointe avant de la semelle 2 et les deux autres vis étant disposées symétriquement en bordure de la plaque 4 dans la partie arrière de la semelle 2.Advantageously, the plate 4 is fixed against the heating body 3 by three screws 7, visible on the figure 5 , one of the screws 7 being placed close to a front point of the sole 2 and the two other screws being placed symmetrically on the edge of the plate 4 in the rear part of the sole 2.

Comme on peut le voir plus en détails sur la figure 3B, la plaque 4 n'est pas au contact direct du corps chauffant 3 au niveau des vis 7 afin de limiter le transfert thermique par conduction dans cette zone.As can be seen in more detail on the Figure 3B , the plate 4 is not in direct contact with the heating body 3 at the level of the screws 7 in order to limit the heat transfer by conduction in this zone.

Conformément à la figure 5, le corps chauffant 3 comporte également des nervures 36, 37 qui font saillie dans la chambre de distribution 34 de vapeur, ces nervures 36, 37 étant situées dans une zone médiane de la semelle 2 et venant en regard d'une zone médiane 41 de la plaque 4 démunie d'ouverture. La hauteur de ces nervures 36, 37 est adaptée pour qu'elles ne viennent pas au contact direct de la plaque 4 lorsque la plaque 4 est assemblée sur le corps chauffant 3 avec les bossages 40 en appui contre les butées 35, un joint en silicone, non représenté sur les figures, venant combler l'espace résultant entre les nervures 36, 37 et la plaque 4 pour assurer une liaison mécanique entre la plaque 4 sur le corps chauffant 3, en complément des vis de fixation.In accordance with the figure 5 , the heating body 3 also comprises ribs 36, 37 which protrude into the steam distribution chamber 34, these ribs 36, 37 being located in a middle zone of the soleplate 2 and coming opposite a middle zone 41 of the plate 4 devoid of opening. The height of these ribs 36, 37 is adapted so that they do not come into direct contact with the plate 4 when the plate 4 is assembled on the heating body 3 with the bosses 40 resting against the stops 35, a silicone seal , not shown in the figures, filling the resulting space between the ribs 36, 37 and the plate 4 to provide a mechanical connection between the plate 4 on the heating body 3, in addition to the fixing screws.

Dans l'exemple particulier de réalisation illustré, les nervures 36, 37 sont constituées par une première nervure 36 présentant une forme générale en U et par une deuxième nervure 37 présentant une forme générale en V, chacune de ces nervures 36, 37 présentant une gorge formant une cavité dans laquelle le joint silicone est injecté, ce joint recouvrant les nervures 36, 37 sur une hauteur de 0,5 mm pour venir au contact de la plaque 4 et contribuer à la fixation de cette dernière.In the particular embodiment illustrated, the ribs 36, 37 are constituted by a first rib 36 having a general U-shape and by a second rib 37 having a general V-shape, each of these ribs 36, 37 having a groove forming a cavity into which the silicone seal is injected, this seal covering the ribs 36, 37 over a height of 0.5 mm to come into contact with the plate 4 and contribute to the fixing of the latter.

La plaque 4 comporte, de part et d'autre de la zone médiane 41, des ouvertures 42, 43 permettant de diffuser la vapeur de la chambre de distribution 34 vers la coiffe 5, la coiffe 5 comprenant en regard de chaque ouverture 42, 43 au moins un trou 50 de sortie de vapeur.The plate 4 comprises, on either side of the central zone 41, openings 42, 43 allowing the vapor to be diffused from the distribution chamber 34 towards the cap 5, the cap 5 comprising, facing each opening 42, 43 at least one steam outlet hole 50 .

De manière avantageuse, la plupart des ouvertures 42 de la plaque 4 présentent un diamètre correspondant sensiblement au diamètre du trou 50 de sortie de vapeur de la coiffe 5 venant en vis-à-vis de manière à ce que la plaque 4 soit au contact direct de la coiffe 5 au voisinage des trous 50 de sortie de vapeur et puisse transmettre la chaleur par conduction dans cette zone.Advantageously, most of the openings 42 of the plate 4 have a diameter corresponding substantially to the diameter of the steam outlet hole 50 of the cap 5 coming opposite so that the plate 4 is in direct contact of the cap 5 in the vicinity of the steam outlet holes 50 and can transmit heat by conduction in this zone.

Certaines ouvertures 43 de la plaque 4 peuvent toutefois avoir une surface plus importante pour limiter localement le transfert thermique par conduction. Ainsi dans l'exemple illustré, la plaque 4 comporte trois ouvertures 43 plus importantes situées respectivement à proximité de la pointe avant, dans la zone centrale de la semelle 2 et à proximité de la partie arrière de la plaque 4, chacune de ces ouvertures alimentant plusieurs trous de sortie de vapeur de la coiffe 5.Certain openings 43 of plate 4 may however have a larger surface to locally limit heat transfer by conduction. Thus in the example illustrated, the plate 4 comprises three larger openings 43 located respectively close to the front tip, in the central zone of the sole 2 and close to the rear part of the plate 4, each of these openings supplying several steam outlet holes of the cap 5.

Le fer à repasser ainsi réalisé présente l'avantage de posséder une coiffe 5 munie d'une surface de repassage qui présente une température relativement homogène de l'ordre de 140°C lorsque la chambre de vaporisation 32 est à une température de l'ordre de 165°C permettant de produire un flux de vapeur en continu de l'ordre de 35 g/min.The iron thus produced has the advantage of having a cap 5 provided with an ironing surface which has a relatively homogeneous temperature of the order of 140° C. when the vaporization chamber 32 is at a temperature of the order 165°C to produce a continuous steam flow of the order of 35 g/min.

En effet, dans la construction de la semelle 2 ainsi réalisée, le transfert thermique par conduction entre le corps chauffant 3 et la plaque 4 est limité aux seuls points de contact 40A situés à l'extrémité des bossages 40, ces derniers présentant une surface très réduite, le reste du transfert thermique s'effectuant par radiation au travers de la chambre de distribution 34. Le nombre important de points de contact 40A et leur faible surface de contact permet d'avoir un excellent contrôle du flux thermique s'établissant par conduction entre le corps chauffant 3 et la plaque 4. De plus, le nombre important de points de contact 40A permet également d'obtenir une bonne maitrise de la distance séparant le fond de la cavité formant la chambre de distribution 34 et la plaque 4, ce qui permet d'avoir un excellent contrôle du flux thermique s'établissant par radiation entre le corps chauffant 3 et la plaque 4 .Indeed, in the construction of the sole 2 thus produced, the heat transfer by conduction between the heating body 3 and the plate 4 is limited only to the contact points 40A located at the end of the bosses 40, the latter having a very reduced, the rest of the heat transfer taking place by radiation through the distribution chamber 34. The large number of contact points 40A and their small contact surface makes it possible to have excellent control of the heat flow established by conduction between the body heater 3 and the plate 4. In addition, the large number of contact points 40A also makes it possible to obtain good control of the distance separating the bottom of the cavity forming the distribution chamber 34 and the plate 4, which makes it possible to to have an excellent control of the heat flow established by radiation between the heating body 3 and the plate 4 .

Enfin, de tels points de contact 40A, portés par des bossages 40 réalisés par emboutissage sur la plaque 4, présentent l'intérêt d'être très économiques à réaliser. Ils présentent de plus l'avantage d'être très peu encombrants, permettant d'obtenir une construction de semelle 2 très compacte.Finally, such contact points 40A, carried by bosses 40 produced by stamping on plate 4, have the advantage of being very economical to produce. They also have the advantage of being very compact, making it possible to obtain a very compact sole 2 construction.

Par ailleurs, la présence de la plaque 4 en aluminium, qui présente une forte conductivité thermique, permet également de contribuer à l'amélioration de l'homogénéité de la température au niveau de la surface de repassage. En effet, si un gradient de température apparait entre différents points de la plaque 4, celui-ci est rapidement atténué par le transfert thermique qui s'établit alors dans l'épaisseur de la plaque 4.Furthermore, the presence of the aluminum plate 4, which has a high thermal conductivity, also makes it possible to contribute to improving the uniformity of the temperature at the level of the ironing surface. Indeed, if a temperature gradient appears between different points of the plate 4, this is quickly attenuated by the heat transfer which is then established in the thickness of the plate 4.

On obtient ainsi un fer à repasser présentant une construction compacte et économique à mettre en œuvre et présentant une température au niveau de la surface de repassage sensiblement constante, autour de 140°C, pour repasser tous les types de textiles sans les détériorer. De plus, une telle construction permet de maintenir la température du corps chauffant au voisinage immédiat de la chambre de vaporisation autour de 165°C ce qui permet de produire un dépit de vapeur en continu de l'ordre de 35 g/min suffisant pour assurer une grande efficacité du repassage.An iron is thus obtained having a compact construction and economical to implement and having a temperature at the level of the ironing surface that is substantially constant, around 140° C., for ironing all types of textiles without damaging them. In addition, such a construction makes it possible to maintain the temperature of the heating body in the immediate vicinity of the vaporization chamber around 165° C. which makes it possible to produce a continuous steam despite of the order of 35 g/min sufficient to ensure high ironing efficiency.

Dans une variante de réalisation non représentée, les bossages en reliefs pourront être réalisés par moulage, ces derniers pouvant être réalisés sur le corps chauffant plutôt que sur la plaque.In a variant embodiment not shown, the bosses in relief could be made by molding, the latter being able to be made on the heating body rather than on the plate.

Dans une variante de réalisation non représentée, l'ensemble plaque en aluminium / coiffe en acier inox pourra être remplacé par une seule plaque en aluminium dont la face inférieure constitue directement la surface de repassage.In a variant embodiment not shown, the aluminum plate/stainless steel cap assembly may be replaced by a single aluminum plate, the underside of which directly constitutes the ironing surface.

Dans une variante de réalisation de l'invention, le fer à repasser pourra comporter un élément chauffant dont la puissance est limitée à 1600W lorsque la tension du réseau électrique domestique est de l'ordre de 120V.In a variant embodiment of the invention, the iron may comprise a heating element whose power is limited to 1600 W when the voltage of the domestic electrical network is of the order of 120 V.
