In addition, the elastic deformation of the tongue makes it possible to exert a permanent force which applies the body of the fuse, and in particular the central part enclosing the fusible material, against the heating body.

Selon encore une autre caractéristique de l'invention, la bride de fixation comporte deux bras latéraux qui maintiennent en position les deux branches latérales du fusible.According to yet another characteristic of the invention, the fastening flange comprises two lateral arms which hold in position the two lateral branches of the fuse.

Le raccordement du conduit d'acheminement du fluide est donc réalisé en temps masqué, simultanément au montage de la platine, et ne nécessite donc pas une opération spécifique.Such a characteristic makes it possible to further simplify the assembly of the iron by allowing the automatic connection of the conduit for conveying the fluid with the distribution circuit formed in the heating body during the fixing of the plate on the heating body. The connection of the fluid flow conduit is thus made in masked time, simultaneously with mounting of the plate, and therefore does not require a specific operation.

Le corps chauffant 4 comporte une face inférieure plane, présentant une extrémité avant pointue et une extrémité arrière large et arrondie, sur laquelle est fixée la plaque de repassage 22 Le corps chauffant 4 présente une face supérieure comprenant une paroi périphérique 42 en saillie délimitant, de manière connue en soi, un circuit de distribution de vapeur fermé dans sa partie supérieure par une plaque de fermeture 43 comprenant une entrée de flux de vapeur 44 destinée à être mise en communication fluidique avec le conduit 30 d'acheminement de vapeur, le circuit de distribution débouchant sur des trous de sorties de vapeur 22A ménagés dans la plaque de repassage 22, visibles sur la figure 7.The heating body 4 comprises a planar lower face, having a pointed front end and a broad and rounded rear end, on which the ironing plate 22 is fixed. The heating body 4 has an upper surface comprising a peripheral wall 42 projecting from in a manner known per se, a steam distribution circuit closed in its upper part by a closure plate 43 comprising a steam flow inlet 44 intended to be placed in fluid communication with the steam transport duct 30, the steam circuit distribution leading to steam outlet holes 22A formed in the ironing plate 22, visible on the figure 7 .

De manière préférentielle, le circuit de distribution de vapeur comprend un dispositif de retenu des condensats, non représenté sur les figures, ménagé sous un dôme 43A qui fait saillie sur la plaque de fermeture 43, le dispositif de retenu étant configuré pour retenir des gouttelettes d'eau entraînées par le flux de vapeur s'écoulant dans le circuit de distribution de vapeur et les vaporiser, ce dispositif de retenu étant semblable à celui décrit plus en détails dans la demande de brevet déposée sous le numéro de demande FR 16 56546 par la demanderesse.Preferably, the steam distribution circuit comprises a condensate retention device, not shown in the figures, formed under a dome 43A which protrudes from the closure plate 43, the retaining device being configured to retain droplets of water. water entrained by the flow of vapor flowing in the vapor distribution circuit and vaporize, this retaining device being similar to that described in more detail in the patent application filed under the application number FR 16 56546 by the plaintiff.

La platine 5 s'étend au-dessus du corps chauffant 4 et forme ainsi un écran thermique entre le corps chauffant 4 et le boîtier 6, la platine 5 étant avantageusement réalisée dans un matériau thermoplastique de type PBT (Polytéréphtalate de butylène) et étant fixée sur le corps chauffant 4 au moyen d'une bride 51 disposée à l'avant du corps chauffant 4 et de deux vis 52 s'engageant dans des alésages taraudés pratiqués à l'arrière du corps chauffant 4.The plate 5 extends above the heating body 4 and thus forms a heat shield between the heating body 4 and the housing 6, the plate 5 being advantageously made of a thermoplastic material of the PBT (polybutylene terephthalate) type and being fixed on the heating body 4 by means of a flange 51 disposed at the front of the heating body 4 and two screws 52 engaging in tapped bores made at the rear of the heating body 4.

Conformément à la figure 5A, la résistance électrique 40 du corps chauffant 4 comporte une borne de connexion 40A à chacune de ses extrémités longitudinales, cette borne de connexion 40A présentant la forme d'un clou rigide, d'un diamètre de l'ordre de 2 mm et d'une longueur de l'ordre de 12 mm, qui débouche obliquement sur la face supérieure dans la partie arrière du corps chauffant 4. Ces deux bornes de connexion constituent des fiches mâles 40A destinées à être connectées automatiquement à deux connecteurs femelles 7 portés par la platine 5 lors de l'assemblage de la platine 5 sur le corps chauffant 4, les deux connecteurs femelles 7 étant reliés au circuit d'alimentation électrique du fer à repasser 2.In accordance with the Figure 5A the electrical resistance 40 of the heating body 4 comprises a connection terminal 40A at each of its longitudinal ends, this connection terminal 40A having the shape of a rigid nail, with a diameter of the order of 2 mm, and a length of the order of 12 mm, which opens obliquely on the upper face in the rear part of the heating body 4. These two connection terminals are male plugs 40A intended to be automatically connected to two female connectors 7 carried by the plate 5 during the assembly of the plate 5 on the heating body 4, the two female connectors 7 being connected to the power supply circuit of the iron 2.

Les deux connecteurs femelles 7 présentent avantageusement une construction identique, illustrée sur la figure 4, chaque connecteur femelle 7 comportant un corps élastiquement déformable réalisé dans un matériau conducteur d'électricité, le corps du connecteur femelle 7 étant avantageusement obtenu par un procédé de découpage puis pliage d'une tôle en acier inox, éventuellement nickelée ou d'une tôle de laiton nickelé ou d'acier nickelé.The two female connectors 7 advantageously have a construction identical, illustrated on the figure 4 , each female connector 7 comprising an elastically deformable body made of an electrically conductive material, the body of the female connector 7 being advantageously obtained by a cutting process then folding of a stainless steel sheet, optionally nickel-plated or sheet metal nickel-plated brass or nickel-plated steel.

Le corps du connecteur femelle 7 comprend avantageusement deux lames 70 de contact s'étendant en regard l'une de l'autre et sensiblement parallèlement l'une à l'autre. Les deux lames 70 s'étendent longitudinalement selon un axe vertical V entre une extrémité proximale, au niveau de laquelle les deux lames 70 sont reliées entre elles par un bras de liaison 71, et une extrémité distale où les lames 70 ménagent entre elles une ouverture de passage 72, l'extrémité distale des lames 70 se prolongeant avantageusement par une partie intermédiaire 73 repliée à 45° vers l'extérieur, puis par une partie terminale 74 plate s'étendant perpendiculairement aux lames 70 vers l'extérieur du connecteur femelle 7.The body of the female connector 7 advantageously comprises two contact blades 70 extending facing one another and substantially parallel to each other. The two blades 70 extend longitudinally along a vertical axis V between a proximal end, at which the two blades 70 are interconnected by a connecting arm 71, and a distal end where the blades 70 form between them an opening passage 72, the distal end of the blades 70 being advantageously extended by an intermediate portion 73 folded at 45 ° outwards, then by a flat end portion 74 extending perpendicularly to the blades 70 towards the outside of the female connector 7 .

Conformément aux figures 3 et 4, les parties intermédiaires 73 du connecteur femelle 7 forment des parois de guidage qui convergent vers l'ouverture de passage 72 et facilitent l'insertion de la fiche mâle 40A de la résistance électrique 40 entre les deux lames 70 du connecteur selon l'axe vertical V lorsque le connecteur femelle 7 est amené verticalement au-dessus de la fiche mâle 40A, les deux lames 70 s'écartant alors selon une direction transversale T tout en enserrant la fiche mâle 40A sous l'effet de la déformation élastique du corps du connecteur.In accordance with Figures 3 and 4 , the intermediate portions 73 of the female connector 7 form guide walls which converge towards the passage opening 72 and facilitate the insertion of the plug 40A of the electrical resistance 40 between the two blades 70 of the connector along the vertical axis V when the female connector 7 is brought vertically above the plug 40A, the two blades 70 then deviating in a transverse direction T while enclosing the plug 40A under the effect of the elastic deformation of the connector body .

De manière préférentielle, le corps du connecteur femelle 7 comporte également une partie latérale 75 plate supportant une borne 75A reliée à un fil électrique du circuit d'alimentation du fer à repasser 2, non représenté sur les figures, la partie latérale 75 plate étant reliée par une traverse 76 au bras de liaison 71 et comportant deux extrémités longitudinales qui débordent latéralement de la traverse 76.Preferably, the body of the female connector 7 also comprises a flat lateral portion 75 supporting a terminal 75A connected to an electric wire of the supply circuit of the iron 2, not shown in the figures, the flat lateral portion 75 being connected by a cross member 76 to the connecting arm 71 and having two longitudinal ends which project laterally from the cross member 76.

Comme on peut le voir sur les figures 2B, 2C et 7B, la platine 5 comporte, pour chacun des connecteurs femelles 7, un logement de réception 55 qui présente une forme sensiblement complémentaire de celle du connecteur femelle 7, les parties terminales 74 plates du connecteur femelle 7 venant prendre place dans des cavités 53 ménagées sur la face inférieure de la platine 5 en prenant appui sur le fond de ces cavités 53, tandis que la partie latérale 75 plate vient prendre appui sur une surface 54 de la face supérieure de la platine 5 disposée en bordure du logement de réception 55.As can be seen on the Figures 2B, 2C and 7B , the plate 5 comprises, for each of the female connectors 7, a receiving housing 55 which has a shape substantially complementary to that of the female connector 7, the flat end portions 74 of the female connector 7 to take place in cavities 53 formed on the lower face of the plate 5 by pressing on the bottom of these cavities 53, while the flat lateral portion 75 bears on a surface 54 of the upper face of the plate 5 disposed at the edge of the receiving housing 55.

Conformément à la figure 2B, la surface 54 comporte deux butées 54A qui viennent coopérer avec les extrémités de la partie latérale 75 plate pour immobiliser le connecteur femelle 7 selon l'axe longitudinal de la platine 5. Un espace 54B est ménagé entre les deux butées 54A pour le passage de la traverse 76, cet espace 54B étant largement supérieur à la largeur de la traverse 76 et les dimensions des cavités 53 étant largement supérieures aux parties terminales 74 plates du connecteur femelle 7 pour permettre un déplacement en translation du connecteur femelle 7 dans son logement de réception 55, selon la direction transversale T, sur plusieurs millimètres mais également un mouvement de rotation sur quelques degrés du connecteur femelle 7 autour de l'axe vertical V, perpendiculaire au plan de la platine 5.In accordance with the Figure 2B the surface 54 comprises two stops 54A which cooperate with the ends of the flat lateral portion 75 to immobilize the female connector 7 along the longitudinal axis of the plate 5. A space 54B is formed between the two stops 54A for the passage of the cross-member 76, this space 54B being much greater than the width of the cross-member 76 and the dimensions of the cavities 53 being much larger than the flat end portions 74 of the female connector 7 to allow a translational movement of the female connector 7 in its receiving housing 55, along the transverse direction T, over several millimeters but also a rotation movement over a few degrees of the female connector 7 about the vertical axis V, perpendicular to the plane of the plate 5.

De manière préférentielle, les lames 70 du connecteur femelle 7 comportent une zone de contact 70A qui présente la forme d'un bossage faisant saillie sur sensiblement toute la hauteur de la lame 70, ce bossage 70A permettant d'augmenter la capacité du connecteur femelle 7 à recevoir une fiche mâle 40A qui n'est pas parfaitement alignée avec l'axe longitudinal L du connecteur femelle 7.Preferably, the blades 70 of the female connector 7 comprise a contact zone 70A which has the shape of a boss protruding over substantially the entire height of the blade 70, this boss 70A for increasing the capacity of the female connector 7 to receive a plug 40A which is not perfectly aligned with the longitudinal axis L of the female connector 7.

A titre d'exemple, les lames 70 de contact présentent une largeur de l'ordre de 5 mm et une hauteur de l'ordre de 1 cm, le bossage 70A présentant la forme d'un grain de riz qui fait saillie sur une hauteur de l'ordre de 1 mm et présentant une largeur de l'ordre de 1 mm. Au repos, l'espace entre les deux lames 70 du connecteur femelle 7 est avantageusement inférieur à 0,7 mm afin d'assurer un serrage sous contrainte de la fiche mâle 40A.For example, the contact blades 70 have a width of the order of 5 mm and a height of about 1 cm, the boss 70A having the shape of a grain of rice that protrudes over a height of the order of 1 mm and having a width of the order of 1 mm. At rest, the space between the two blades 70 of the female connector 7 is advantageously less than 0.7 mm in order to ensure a constrained clamping of the plug 40A.

Plus particulièrement selon l'invention, et comme on peut le voir sur les figures 7 et 7A, la platine 5 supporte également un fusible 8 qui est destiné à couper le circuit d'alimentation du fer à repasser 2, et notamment l'alimentation de la résistance électrique 40, lorsque la température du corps chauffant 4 s'élève au-delà d'une température prédéterminée correspondant à la température du fusible 8.More particularly according to the invention, and as can be seen on the Figures 7 and 7A , the plate 5 also supports a fuse 8 which is intended to cut the supply circuit of the iron 2, and in particular the supply of the electrical resistance 40, when the temperature of the heating body 4 rises beyond a predetermined temperature corresponding to the temperature of the fuse 8.

De manière préférentielle, le fusible 8 est un fusible de type cartouche présentant un corps en forme de U et possédant les mêmes caractéristiques techniques que celui vendu sous la référence SF 184 par la société Nec Shott., ce fusible 8 étant disposé dans un logement 56 ménagé dans la partie arrière de la platine 5.Preferably, the fuse 8 is a cartridge-type fuse having a U-shaped body and having the same technical characteristics as that sold under the reference SF 184 by the company Nec Shott., this fuse 8 being disposed in a housing 56 formed in the rear part of the plate 5.

Le logement 56 présente la forme d'une ouverture traversante, visible sur la figure 10, et comporte deux pattes de maintien 56A s'étendant au niveau de la face inférieure de la platine 5 sur lesquelles les extrémités longitudinales du fusible 8 viennent reposer lorsque le fusible 8 est introduit dans le logement 56 par la face supérieure de la platine 5.The housing 56 has the shape of a through opening, visible on the figure 10 , and comprises two retaining lugs 56A extending at the lower face of the plate 5 on which the longitudinal ends of the fuse 8 come to rest when the fuse 8 is introduced into the housing 56 by the upper face of the plate 5.

Comme cela est illustré sur la figure 11, le fusible 8 est maintenu dans le logement 56 au moyen d'une bride de fixation 57, réalisée en tôle pliée, qui est rapportée sur la face supérieure de la platine 5 et qui est fixée sur un puits de fixation 46 du corps chauffant 4, visible sur la figure 5A, au moyen d'une vis 57A. La bride de fixation 57 est avantageusement surmontée d'un cache 58 en matière plastique qui sert de pièce de maintien et de guidage de différents fils électriques nécessaires au fonctionnement de l'appareil.As illustrated on the figure 11 , the fuse 8 is held in the housing 56 by means of a fastening flange 57, made of folded sheet metal, which is attached to the upper face of the plate 5 and which is fixed to a fixing shaft 46 of the heating body 4 , visible on the Figure 5A by means of a screw 57A. The fixing flange 57 is advantageously surmounted by a plastic cover 58 which serves as a holding and guiding part of various electrical wires necessary for the operation of the apparatus.

De manière préférentielle, la bride de fixation 57 présente une languette 57B élastiquement déformable qui vient prendre appui sur le dessus du fusible 8 lorsque ce dernier est disposé dans le logement 56 et comporte deux bras latéraux 57C qui viennent enserrer les branches latérales du fusible 8 en forme de U de manière à maintenir ces dernières orientées vers le haut.Preferably, the fixing flange 57 has a tongue elastically deformable 57B which bears on the top of the fuse 8 when the latter is disposed in the housing 56 and has two lateral arms 57C which clasp the lateral branches of the fuse 8 shape of U so as to keep the latter oriented upwards.

Conformément aux figures 5B et 6, le corps chauffant 4 comporte un socle 45 de réception du fusible 8 présentant la forme d'un demi cylindre, ouvert à son extrémité supérieure, porté par un plot 45A obtenu directement avec la fonderie en aluminium du corps chauffant 4, ce plot 45A faisant saillie à l'arrière de la paroi périphérique 42 délimitant le circuit de distribution de vapeur.In accordance with Figures 5B and 6 , the heating body 4 comprises a base 45 for receiving the fuse 8 having the shape of a half-cylinder, open at its upper end, carried by a pad 45A obtained directly with the aluminum foundry of the heating body 4, this pad 45A making protrusion at the rear of the peripheral wall 42 defining the steam distribution circuit.

Ainsi, lorsque la platine 5 est fixée sur le corps chauffant 4, le fusible 8 porté par la platine 5 vient se positionner automatiquement sur le socle 45 ménagé sur le corps chauffant 4, la longueur de languette 57B de la bride de fixation 57 étant dimensionnée pour se déformer élastiquement en contraignant le fusible 8 contre le socle 45 lorsque la vis 57A est serrée de manière à optimiser le transfert thermique entre le fusible 8 et le corps chauffant 4 malgré les dispersions de fabrication.Thus, when the plate 5 is fixed on the heating body 4, the fuse 8 carried by the plate 5 is automatically positioned on the base 45 formed on the heating body 4, the tongue length 57B of the fastening flange 57 being dimensioned to deform elastically by forcing the fuse 8 against the base 45 when the screw 57A is tightened so as to optimize the heat transfer between the fuse 8 and the heating body 4 despite the manufacturing dispersions.

De manière préférentielle, la platine 5 supporte également un connecteur fluidique 9 permettant de réaliser une liaison étanche entre le conduit 30 d'acheminement de vapeur, en provenance de la base 1, et l'entrée de flux de vapeur 44 ménagée sur la plaque de fermeture 43 du corps chauffant 4.Preferably, the plate 5 also supports a fluidic connector 9 making it possible to form a tight connection between the steam transport duct 30 coming from the base 1 and the steam flow inlet 44 formed on the heating plate. closure 43 of the heating body 4.

Comme on peut le voir sur les figures 5A et 7C à 10, l'entrée de flux de vapeur 44 est disposée au sommet d'un tube de raccordement 44A tronconique faisant saillie sur la plaque de fermeture 43 et le connecteur fluidique 9 comporte un corps comprenant une cavité 90 ouverte à son extrémité inférieure dans laquelle est engagé le tube de raccordement 44A, la cavité 90 comprenant une partie supérieure tronconique 90A communiquant avec un tube de raccordement 91 sur lequel est emmanché le conduit 30 d'acheminement de vapeur.As can be seen on the Figures 5A and 7C to 10 , the vapor flow inlet 44 is disposed at the top of a frustoconical connecting tube 44A projecting from the closing plate 43 and the fluidic connector 9 comprises a body comprising a cavity 90 open at its lower end in which is engaged the connecting tube 44A, the cavity 90 comprising a frustoconical upper portion 90A communicating with a connecting tube 91 on which is fitted the conduit 30 for the conveyance of steam.

La cavité 90 comprend, sous la partie supérieure tronconique 90A, une partie cylindrique 90B recevant un joint 94 annulaire, à lèvres, et comprenant une extrémité inférieure ouverte par laquelle vient s'engager le tube de raccordement 44A. La cavité 90 présente, à la jonction entre la partie supérieure tronconique 90A et la partie cylindrique 90B, un épaulement contre lequel le joint 94 est appliqué, le joint 94 étant immobilisé contre cet épaulement au moyen d'une bague 95, de type circlips, qui est fixée dans la cavité 90 sous le joint 94, la bague 95 présentant avantageusement un bord inférieur chanfreiné qui converge vers l'intérieur de la cavité 90.The cavity 90 comprises, under the frustoconical upper portion 90A, a cylindrical portion 90B receiving an annular seal 94, with lips, and comprising an open bottom end through which is engaged the connecting tube 44A. The cavity 90 has, at the junction between the frustoconical upper portion 90A and the cylindrical portion 90B, a shoulder against which the seal 94 is applied, the seal 94 being immobilized against this shoulder by means of a ring 95, circlip type, which is fixed in the cavity 90 under the seal 94, the ring 95 advantageously having a chamfered lower edge which converges towards the inside of the cavity 90.

De manière préférentielle, la bague 95 est fixée dans la cavité 90 au moyen de deux ergots 95A portés par la bague 95, ces ergots 95A s'engageant dans deux ouvertures ménagées symétriquement dans la cavité 90, ces ouvertures débouchant dans des rainures 96 réalisées sur la périphérie du corps du connecteur fluidique 9.Preferably, the ring 95 is fixed in the cavity 90 by means of two lugs 95A carried by the ring 95, these lugs 95A engaging in two openings formed symmetrically in the cavity 90, these openings opening into grooves 96 made on the periphery of the body of the fluidic connector 9.

Conformément aux figures 8 et 10, la partie externe du corps du connecteur fluidique 9 comporte, au voisinage du sommet de la partie cylindrique 90B de la cavité 90, une collerette 92 destinée à venir reposer en bordure d'une ouverture 59 circulaire ménagée dans la platine 5 et comprend deux oreilles 97 de verrouillage s'étendant radialement à la base du connecteur fluidique 9, destinées à s'engager dans deux encoches 59A ménagées en bordure de l'ouverture 59, puis à glisser sous la platine 5 par rotation du connecteur fluidique 9 sur un quart de tour pour réaliser une liaison de type baïonnette.In accordance with Figures 8 and 10 , the external part of the body of the fluidic connector 9 comprises, in the vicinity of the top of the cylindrical portion 90B of the cavity 90, a flange 92 intended to rest at the edge of a circular opening 59 formed in the plate 5 and comprises two ears 97 locking extending radially to the base of the fluid connector 9, intended to engage in two notches 59A formed at the edge of the opening 59, then slide under the plate 5 by rotation of the fluid connector 9 on a quarter of turn for make a bayonet type connection.

De manière préférentielle, le système de fixation du connecteur fluidique 9 est dimensionné pour autoriser un débattement radial du connecteur fluidique 9 d'au moins un millimètre dans le plan de la platine 5 afin de permettre un auto-centrage du connecteur sur le tube de raccordement 44A lors de l'assemblage de la platine 5 sur le corps chauffant 4.Preferably, the fastening system of the fluidic connector 9 is dimensioned to allow a radial clearance of the fluidic connector 9 of at least one millimeter in the plane of the plate 5 to allow a self-centering of the connector on the connecting tube 44A during the assembly of the plate 5 on the heating body 4.

A cet effet, la partie externe du connecteur fluidique 9, engagée dans l'ouverture 59 circulaire, présente un diamètre légèrement inférieur au diamètre de l'ouverture 59 circulaire. A titre d'exemple l'ouverture 59 circulaire pourra présenter un diamètre supérieur de l'ordre de 2 mm par rapport au diamètre du connecteur fluidique 9.For this purpose, the external part of the fluidic connector 9, engaged in the opening 59 circular, has a diameter slightly smaller than the diameter of the opening 59 circular. By way of example, the circular opening 59 may have a diameter greater than about 2 mm with respect to the diameter of the fluidic connector 9.

Le fer à repasser 2 ainsi réalisé présente l'avantage d'être équipé d'une platine 5 fonctionnelle formant un sous-ensemble qui supporte le circuit d'alimentation électrique de la résistance électrique 40 du corps chauffant 4, le fusible 8 de sécurité contre la surchauffe associée à ce circuit d'alimentation et le connecteur fluidique 9 permettant de relier le conduit 30 d'acheminement de la vapeur au circuit de distribution de vapeur ménagé dans le corps chauffant 4.The iron 2 thus produced has the advantage of being equipped with a functional plate 5 forming a subassembly which supports the electrical supply circuit of the electrical resistance 40 of the heating body 4, the safety fuse 8 against the superheating associated with this supply circuit and the fluidic connector 9 making it possible to connect the conduit 30 for conveying the steam to the steam distribution circuit formed in the heating body 4.

En particulier, cette platine 5 présente l'avantage de pouvoir être assemblée simplement sur le corps chauffant 4 en amenant cette dernière verticalement au-dessus du corps chauffant 4, par exemple de manière automatisée au moyen d'un robot, puis en rapprochant la platine 5 du corps chauffant 4 de manière à amener les fiches mâles 40A de la résistance électrique 40 en regard des connecteurs femelles 7 portées par la platine 5, le connecteur fluidique 9 en regard du tube de raccordement 44A et le fusible 8 en regard du socle 45 de réception.In particular, this plate 5 has the advantage of being simply assembled on the heating body 4 by bringing it vertically above the heating body 4, for example in an automated manner by means of a robot, then bringing the platinum closer 5 of the heating body 4 so as to bring the male plugs 40A of the electrical resistance 40 opposite the female connectors 7 carried by the plate 5, the fluid connector 9 facing the connecting tube 44A and the fuse 8 opposite the base 45 reception.

Lors de cet assemblage, l'accostage de la platine 5 sur le corps chauffant 4 peut être effectué sans qu'un positionnement précis des pièces 7, 8, 9 sur la platine 5 soit nécessaire.During this assembly, the docking of the plate 5 on the heating body 4 can be performed without precise positioning of the parts 7, 8, 9 on the plate 5 is necessary.

En effet, la forme du connecteur femelle 7 et sa fixation autorisent un débattement latéral du connecteur femelle 7 par rapport à l'axe longitudinal de la platine 5 qui va permettre un auto-centrage du connecteur femelle 7 sur la fiche mâle 40A même si cette dernière est décalée d'un peu plus d'un millimètre par rapport à la position idéalement requise. En particulier, du fait des tolérances de fabrication des corps chauffant 4, la position de la fiche mâle 40A des résistances électriques peut varier de plus ou moins 1 mm dans toutes les directions mais aussi angulairement.Indeed, the shape of the female connector 7 and its attachment allow a lateral clearance of the female connector 7 relative to the longitudinal axis of the plate 5 which will allow self-centering of the female connector 7 on the male plug 40A even if this The last is shifted a little more than a millimeter from the ideally required position. In particular, because of the manufacturing tolerances of the bodies heating 4, the position of the plug 40A of the electrical resistances can vary from plus or minus 1 mm in all directions but also angularly.

Ainsi, la présence des bossages sur les zones de contact et la faculté du connecteur femelle 7 à pivoter légèrement sur lui-même dans son logement de réception 55, autour de l'axe vertical V, va permettre de garantir une connexion fiable des connecteurs femelle 7 sur les fiches mâles 40A même si ces dernières ne sont pas disposées parfaitement parallèlement à l'axe longitudinal du corps chauffant 4.Thus, the presence of the bosses on the contact areas and the ability of the female connector 7 to rotate slightly on itself in its receiving housing 55 around the vertical axis V, will ensure a reliable connection of the female connectors 7 on the plugs 40A even if these are not arranged perfectly parallel to the longitudinal axis of the heating body 4.

De plus, le dispositif de maintien du fusible 8 sur la platine 5 permet également de simplifier l'assemblage du fer à repasser 2, le bon échange thermique entre le fusible 8 et le corps chauffant 4 étant garanti grâce à la mise sous contrainte du fusible 8 par la bride de fixation 57, un éventuel mauvais alignement du fusible 8 par rapport au socle 45 étant compensé par une déformation élastique de la bride de fixation 57, et notamment des deux bras latéraux 57C de cette dernière, qui contribue à augmenter encore la mise sous contrainte du fusible 8 sur le socle 45 et donc à optimiser le transfert thermique.In addition, the device for holding the fuse 8 on the plate 5 also makes it possible to simplify the assembly of the iron 2, the good heat exchange between the fuse 8 and the heating element 4 being guaranteed by the stressing of the fuse 8 by the fastening flange 57, a possible misalignment of the fuse 8 with respect to the base 45 being compensated by an elastic deformation of the fastening flange 57, and in particular of the two lateral arms 57C of the latter, which contributes to further increasing the stressing the fuse 8 on the base 45 and thus to optimize the heat transfer.

En particulier, la mise sous contrainte du fusible 8 par la bride de fixation 57 en métal présente l'avantage de garantir un bon contact thermique du fusible 8 contre le corps chauffant 4 même si la platine 5, réalisée en matériau plastique dans l'exemple particulier de réalisation décrit, se déforme sous l'effet de la chaleur.In particular, the stressing of the fuse 8 by the metal fixing flange 57 has the advantage of guaranteeing good thermal contact of the fuse 8 against the heating body 4 even if the plate 5, made of plastic material in the example particular embodiment described, is deformed under the effect of heat.

Enfin, le système de fixation du connecteur fluidique 9 sur la platine 5 présente l'avantage d'autoriser un débattement latéral du connecteur fluidique 9 sur plusieurs millimètres qui va permettre un auto-centrage du connecteur fluidique 9 sur le tube de raccordement 44A en cas de défaut d'alignement lors de l'accostage de la platine 5 sur le corps chauffant.Finally, the fixing system of the fluidic connector 9 on the plate 5 has the advantage of allowing a lateral displacement of the fluidic connector 9 over several millimeters which will allow self-centering of the fluidic connector 9 on the connecting tube 44A in case misalignment when docking the plate 5 on the heating body.

En particulier, la forme chanfreinée de la bague 95 et la forme tronconique du tube de raccordement 44A vont coopérer l'une avec l'autre pour réaliser le centrage automatique du connecteur fluidique 9 sur le tube de raccordement de manière à ce que le joint 94 assure une parfaite étanchéité de la liaison.In particular, the chamfered shape of the ring 95 and the frustoconical shape of the connecting tube 44A will cooperate with each other to achieve the automatic centering of the fluidic connector 9 on the connecting tube so that the seal 94 ensures a perfect seal of the connection.

L'étanchéité ainsi réalisée, au moyen d'un joint à lèvres interposé entre la surface interne de la cavité 90 et la surface externe du tube de raccordement 44A, présente l'avantage de garantir l'étanchéité de la liaison sans qu'il soit nécessaire d'avoir une compression importante du joint 94. Il n'est ainsi pas nécessaire d'appliquer la platine fonctionnelle 5 contre le corps chauffant 4 avec une forte contrainte de compression au niveau du connecteur fluidique 9. De plus, l'étanchéité ainsi réalisée présente l'avantage d'être fiable et d'être peu sujette à une perte d'étanchéité dans le cas de forte pression de vapeur.The sealing thus produced, by means of a lip seal interposed between the inner surface of the cavity 90 and the outer surface of the connecting tube 44A, has the advantage of ensuring the tightness of the connection without being necessary to have a significant compression of the seal 94. It is thus not necessary to apply the functional plate 5 against the heating body 4 with a high compressive stress at the fluid connector 9. In addition, the seal thus produced has the advantage to be reliable and to be less prone to loss of tightness in the case of high vapor pressure.

Le fer à repasser 2 ainsi réalisé permet d'optimiser le temps d'assemblage du fer à repasser en permettant l'assemblage du fusible 8 sur le corps chauffant 4 simultanément à la mise en place de la platine 5 sur le corps chauffant 4. Ainsi, l'assemblage du fusible 8 sur le corps chauffant 4 est effectué automatiquement lors de l'assemblage de la platine 5 de sorte qu'il n'est pas nécessaire de prévoir une opération d'assemblage spécifique pour la mise en place du fusible, ce qui permet un gain de temps et une réduction du cout de fabrication du fer à repasser.The iron 2 thus produced allows to optimize the assembly time of the iron by allowing the assembly of the fuse 8 on the heating body 4 simultaneously with the establishment of the plate 5 on the heating body 4. Thus , the assembly of the fuse 8 on the heating body 4 is performed automatically during the assembly of the plate 5 so that it is not necessary to provide a specific assembly operation for the establishment of the fuse, which saves time and reduces the cost of manufacturing the iron.

De plus, l'établissement simultané de la connexion électrique et de la connexion fluidique du corps chauffant 4 lors de la mise en place de la platine 5 fonctionnelle sur le corps chauffant 4 permet également de réduire le temps d'assemblage du fer à repasserIn addition, the simultaneous establishment of the electrical connection and the fluidic connection of the heating body 4 during the establishment of the functional plate 5 on the heating body 4 also reduces the assembly time of the iron.

Enfin, la platine 5 fonctionnelle présente également l'avantage de constituer un écran thermique qui limite l'élévation de la température du boîtier 6 surmontant le corps chauffant 4.Finally, the functional plate 5 also has the advantage of constituting a heat shield which limits the rise in the temperature of the housing 6 above the heating body 4.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi dans une variante de réalisation non représentée, l'ensemble de la vapeur diffusée au travers des trous de sortie de vapeur de la plaque de repassage pourra être produite dans une chambre de vaporisation ménagée dans le corps chauffant du fer à repasser, le connecteur fluidique porté par la platine fonctionnelle servant alors à raccorder hydrauliquement un orifice d'injection d'eau dans la chambre de vaporisation avec un conduit d'arrivée d'eau en provenance d'un réservoir porté par le boitier ou porté par une base séparée de ce dernier.Thus, in an embodiment variant not shown, all of the vapor diffused through the steam outlet holes of the ironing plate can be produced in a vaporization chamber formed in the heating body of the iron, the fluidic connector carried by the functional plate then serving to hydraulically connect a water injection orifice in the vaporization chamber with a water inlet pipe from a tank carried by the housing or carried by a separate base thereof latest.

Ainsi dans une variante de réalisation non représentée, la platine fonctionnelle pourra être réalisée à partir d'une feuille d'acier découpée et surmoulée de matière plastique, l'utilisation d'une base métallique permettant d'avoir une platine présentant une meilleure résistance à la chaleur et de réaliser des bandes conductrices pour établir des connexions électriques directement dans la platine.Thus, in an embodiment variant not shown, the functional plate may be made from a sheet of steel cut and overmoulded plastic material, the use of a metal base to have a platinum having a better resistance to heat and make conductive strips to make electrical connections directly into the board.
