Description

La présente invention concerne un procédé de fabrication d'une platine fonctionnelle pour fer à repasser à vapeur, portant les organes d'admission d'eau, de réglage du débit d'eau, les organes de réglage de la température, les organes de connexion électrique et les organes de fixation de la platine au fer à repasser.The present invention relates to a method of manufacturing a functional plate for a steam iron, carrying the water intake members, for adjusting the water flow rate, the temperature adjustment members, the connection members electric and the fixing elements of the plate to the iron.

L'invention vise également la platine fonctionnelle pour fer à repasser, obtenue notamment par le procédé précité.The invention also relates to the functional plate for an iron, obtained in particular by the aforementioned method.

L'invention concerne en outre un fer à repasser à vapeur comportant une telle platine fonctionnelle.The invention further relates to a steam iron comprising such a functional plate.

Une telle platine fonctionnelle a été décrite dans la demande de brevet français n° 2 664 916 au nom de la demanderesse.Such a functional plate has been described in French patent application No. 2,664,916 in the name of the applicant.

Cette platine porte la majeure partie des organes d'admission et de réglage du débit d'eau ainsi qu'une partie des organes de réglage de la température.This plate carries the major part of the admission and water flow regulating organs as well as a part of the temperature regulating organs.

Une telle platine simplifie considérablement le montage d'un fer à repasser à vapeur, puisqu'elle constitue un module préfabriqué et préréglé, prêt à être monté dans le fer à repasser, moyennant un minimum d'opérations de fixation mécanique et de raccordements électriques.Such a plate considerably simplifies the assembly of a steam iron, since it constitutes a prefabricated and preset module, ready to be mounted in the iron, with a minimum of mechanical fixing operations and electrical connections.

La platine fonctionnelle décrite dans la demande de brevet précitée ainsi que les organes qu'elle porte sont entièrement moulés en matière plastique.The functional plate described in the aforementioned patent application as well as the members which it carries are entirely molded in plastic material.

Cette platine en matière plastique constitue ainsi un support mécanique des organes et un support isolant permettant d'isoler entre eux les différentes connexions électriques ainsi que les organes électriques de réglage de la température et de sécurité contre la surchauffe.This plastic plate thus constitutes a mechanical support for the members and an insulating support making it possible to isolate therebetween the various electrical connections as well as the electrical members for adjusting the temperature and safety against overheating.

Après le moulage des parties en matière plastique, il était nécessaire de monter sur la platine des conducteurs électriques pour établir les connexions avec la résistance chauffante de la semelle du fer et avec les organes électriques de réglage de la température et de sécurité contre la surchauffe.After the molding of the plastic parts, it was necessary to mount on the plate of the electrical conductors to establish the connections with the heating resistor of the soleplate of the iron and with the electrical organs for adjusting the temperature and safety against overheating.

Le but de la présente invention est de fournir un procédé de fabrication d'une platine fonctionnelle pour fer à repasser à vapeur qui permette d'abaisser encore davantage les coûts de fabrication et de montage.The object of the present invention is to provide a method of manufacturing a functional plate for a steam iron which makes it possible to lower still further the manufacturing and assembly costs.

L'invention vise ainsi un procédé de fabrication d'une platine fonctionnelle pour fer à repasser à vapeur, portant les organes d'admission d'eau, de réglage du débit d'eau, les organes de réglage de la température, les organes de connexion électrique et les organes de fixation de la platine au fer à repasser.The invention thus relates to a method of manufacturing a functional plate for a steam iron, carrying the water intake organs, regulating the water flow, the temperature regulating organs, the organs of electrical connection and fixing elements of the plate to the iron.

Suivant l'invention, ce procédé est caractérisé par les étapes suivantes:

  • a) on réalise par découpage une plaque métallique comportant des ouvertures, des trous et des bandes métalliques reliées les unes aux autres et avec la partie principale de la plaque;
  • b) on surmoule, en une seule opération, sur lesdites ouvertures, trous et bandes métalliques les éléments en matière plastique nécessaires pour constituer les organes d'admission et de réglage du débit d'eau, les organes de réglage de la température et les organes destinés à isoler électriquement les connexions électriques;
  • c) on découpe certaines parties métalliques reliant les bandes métalliques entre elles et avec la partie principale de la plaque, pour constituer des connexions électriques isolées électriquement.
According to the invention, this process is characterized by the following stages:
  • a) a metal plate is produced by cutting comprising openings, holes and metal strips connected to each other and with the main part of the plate;
  • b) the plastic elements necessary to constitute the admission and water flow control members, the temperature control members and the members are overmolded, in a single operation, on said openings, holes and metal strips. intended to electrically isolate electrical connections;
  • c) cutting certain metal parts connecting the metal strips together and with the main part of the plate, to form electrically isolated electrical connections.

La platine ainsi obtenue est constituée d'une part par un métal et d'autre part par des pièces moulées en matière plastique. Etant donné que la majeure partie de cette platine est un métal embouti et découpé, le coût de fabrication de la platine est très réduit.The plate thus obtained is formed on the one hand by a metal and on the other hand by molded plastic parts. Since the major part of this plate is a stamped and cut metal, the manufacturing cost of the plate is very reduced.

De plus, l'utilisation d'une plaque en métal permet de réaliser dans celle-ci lors de l'opération de découpage, des bandes conductrices permettant d'établir les connexions électriques, étant entendu que les isolations électriques nécessaires peuvent être réalisées aisément lors du surmoulage de la matière plastique.In addition, the use of a metal plate makes it possible to produce therein during the cutting operation, conductive strips making it possible to establish the electrical connections, it being understood that the necessary electrical insulations can be easily carried out during plastic overmolding.

On obtient ainsi une platine fonctionnelle prête à être fixée dans le fer à repasser.A functional plate is thus obtained ready to be fixed in the iron.

Selon une version préférée de l'invention, les extrémités desdites bandes sont conformées pour être aptes à recevoir par emboîtement des cosses de connexion électrique et sont repliées sensiblement à angle droit par rapport au reste de la bande.According to a preferred version of the invention, the ends of said strips are shaped to be able to receive by interlocking electrical connection lugs and are folded substantially at right angles to the rest of the strip.

L'invention vise également une platine fonctionnelle pourfer à repasser à vapeur, portant les organes d'admission d'eau, de réglage du débit d'eau, les organes de réglage de la température, les organes de connexion électrique et les organes de fixation de la platine au fer à repasser.The invention also relates to a functional plate for steam ironing, carrying the water intake organs, regulating the water flow rate, the temperature regulating organs, the electrical connection members and the fixing members. from platinum to iron.

Suivant l'invention, cette platine comprend une plaque métallique emboutie et découpée comportant des ouvertures, des trous et des bandes métalliques découpées dans ladite plaque, sur lesdites ouvertures, trous et bandes, sont surmoulés des éléments en matière plastique constituant au moins une partie des organes d'admission et de réglage du débit d'eau, au moins une partie des organes de réglage de la température de chauffage du fer, et au moins une partie des organes d'isolation des connexions électriques.According to the invention, this plate comprises a stamped and cut metal plate having openings, holes and metal strips cut from said plate, on said openings, holes and strips, are overmolded plastic elements constituting at least part of the water flow intake and adjustment members, at least part of the iron heating temperature adjustment members, and at least part of the electrical connection insulation members.

La plaque peut être en un métal bon marché tel que de l'acier revêtu de zinc.The plate can be of an inexpensive metal such as zinc coated steel.

Les figures 1 à 5 illustrent les étapes successives du procédé de fabrication d'une platine fonctionnelle 1 pour fer à repasser à vapeur. Cette platine 1 (voir figure 5) porte les organes 2 d'admission d'eau et de réglage du débit d'eau, les organes 3 de réglage de la température, les organes 4 de connexion électrique et les organes 5, 6, 7 de fixation de la platine 1 au fer à repasser.Figures 1 to 5 illustrate the successive stages of the manufacturing process of a functional plate 1 for a steam iron. This plate 1 (see FIG. 5) carries the bodies 2 for water admission and for adjusting the water flow, the bodies 3 for adjusting the temperature, the bodies 4 for electrical connection and the bodies 5, 6, 7 fixing plate 1 to the iron.

Dans une première étape, on réalise (voir figure 1), par emboutissage et découpage, une plaque métallique 8 comportant des ouvertures telles que 9, 10, 11, des trous tels que 12 et bandes métalliques 13,14, 15, 16 reliées les unes aux autres par des ponts tels que 16a et avec la partie principale de la plaque 8.In a first step, a metal plate 8 is formed (see FIG. 1), by stamping and cutting, having openings such as 9, 10, 11, holes such as 12 and metal strips 13, 14, 15, 16 connected together. to each other by bridges such as 16a and with the main part of the plate 8.

Dans une deuxième opération (voir figures 2 et 3), on surmoule, en une seule opération, sur lesdites ouvertures 9, 10, 11, trous et bandes métalliques 13, 14, 15, 16, les éléments en matière plastique nécessaires tels que 17, 18, 19, 20, 21, 22 pour constituer les organes d'admission et de réglage du débit d'eau, les organes de réglage de la température et les organes destinés à isoler électriquement les connexions électriques 13, 14, 15.In a second operation (see FIGS. 2 and 3), the necessary plastic elements such as 17 are overmolded, in a single operation, on said openings 9, 10, 11, holes and metal strips 13, 14, 15, 16 , 18, 19, 20, 21, 22 to constitute the intake and adjustment members of the water flow, the temperature adjustment members and the members intended to electrically isolate the electrical connections 13, 14, 15.

Dans une troisième étape (voir figure 3), on découpe certaines parties métalliques telles que 23, 24, 25 reliant les bandes métalliques 13, 14, 15, 16 entre elles et avec la partie principale de la plaque 8, pour constituer des connexions électriques isolées électriquement.In a third step (see Figure 3), certain metal parts are cut such as 23, 24, 25 connecting the metal strips 13, 14, 15, 16 to each other and to the main part of the plate 8, to form electrical connections electrically isolated.

Dans l'exemple représenté sur les figures, l'une 16 des bandes métalliques est reliée à un côté 8a de la plaque 8, différent du côté 8b auquel sont reliées les autres bandes 13, 14, 15. Dans cet exemple, après l'opération de découpage des parties 24, 25, la bande 16 est séparée de la plaque 8 pour être placée à un autre endroit.In the example shown in the figures, one 16 of the metal strips is connected to one side 8a of the plate 8, different from the side 8b to which the other strips 13, 14, 15 are connected. In this example, after the cutting operation of the parts 24, 25, the strip 16 is separated from the plate 8 to be placed in another place.

Les figures 2 et 3, montrent par ailleurs que les organes tels que 17,18,19,20,21,22 sont surmoulés sur la plaque 8 de façon à être fixés à celle-ci autour des bords des ouvertures ou trous tels que 9, 10, 11, 11 a découpés dans la plaque 8. Les organes surmoulés sont ainsi parfaitement fixés à la plaque 8.Figures 2 and 3 also show that the members such as 17,18,19,20,21,22 are molded onto the plate 8 so as to be fixed thereto around the edges of the openings or holes such as 9 , 10, 11, 11 a cut from the plate 8. The overmolded members are thus perfectly fixed to the plate 8.

On voit d'autre part sur la figure 5, que les extrémités 13a, 14a, 15a, 17a des bandes 13, 14, 15, 16 sont conformées pour être aptes à recevoir par em- boitement des cosses de connexion électrique et sont repliées sensiblement à angle droit par rapport au reste de la bande.On the other hand, it can be seen in FIG. 5 that the ends 13a, 14a, 15a, 17a of the bands 13, 14, 15, 16 are shaped to be able to receive by socket electrical connection lugs and are folded substantially at right angles to the rest of the strip.

On va maintenant décrire en détail, en référence à la figure 5, la platine fonctionnelle obtenue par le procédé selon l'invention. Cette platine 1 porte les organes 2 d'admission d'eau et de réglage du débit d'eau, les organes 3 de réglage de la température, les organes 4 de connexion électrique et les organes 5, 6, 7 de fixation de la platine 1 à la semelle d'un fer à repasser.We will now describe in detail, with reference to FIG. 5, the functional plate obtained by the method according to the invention. This plate 1 carries the organs 2 for water admission and for adjusting the water flow, the organs 3 for adjusting the temperature, the organs 4 for electrical connection and the organs 5, 6, 7 for fixing the plate. 1 with the sole of an iron.

Conformément à l'invention, la platine 1 comprend une plaque métallique 8 emboutie et découpée comportant (voir figure 1) des ouvertures 9, 10, 11, des trous 12 et des bandes métalliques 13, 14, 15, 16 découpées dans ladite plaque 8.According to the invention, the plate 1 comprises a stamped and cut metal plate 8 comprising (see FIG. 1) openings 9, 10, 11, holes 12 and metal strips 13, 14, 15, 16 cut out from said plate 8 .

Sur lesdites ouvertures, trous et bandes sont surmoulés des éléments 17, 18, 19, 20, 21, 22 en matière plastique constituant au moins une partie des organes 17 d'admission et de réglage du débit d'eau, au moins une partie des organes 3 de réglage de la température de chauffage du fer, et au moins une partie des organes d'isolation des connexions électriques 4.On said openings, holes and strips are overmolded elements 17, 18, 19, 20, 21, 22 of plastic material constituting at least a part of the organs 17 for admission and adjustment of the water flow, at least a part of the organs 3 for adjusting the heating temperature of the iron, and at least a part of the organs for isolating the electrical connections 4.

La plaque 8 peut être réalisée par exemple en tôle d'acier revêtu de zinc, d'épaisseur égale à 0,5 mm environ.The plate 8 can be made for example from sheet steel coated with zinc, of thickness equal to approximately 0.5 mm.

Dans l'exemple représenté, sur l'une 9 des ouvertures découpées dans la plaque est surmoulé le manchon 17 recevant le boisseau 30 du dispositif d'admission et de réglage du débit d'eau. A ce manchon 17 sont associés un joint supérieur 31 et un joint inférieur 32 pour réaliser l'étanchéité avec l'ouverture d'admission 33 (voir figure 6) de l'eau dans la chambre de vaporisation de la semelle du fer.In the example shown, on one of the openings cut in the plate 9 is overmolded the sleeve 17 receiving the plug 30 of the intake device and adjusting the water flow. To this sleeve 17 are associated an upper seal 31 and a lower seal 32 for sealing with the inlet opening 33 (see FIG. 6) of the water in the vaporization chamber of the soleplate of the iron.

Comme indiqué sur la figure 1, la plaque 8 comporte deux fentes 10, 11 parallèles s'étendant vers l'ouverture 9 portant le manchon 17. Dans chaque fente 10, 11 est surmoulée (voir figures 3 ou 5) une glissière 18, 19. Ces deux glissières 18, 19 servent à guider un tiroir 36 coopérant avec le boisseau 30 et avec le dispositif de réglage de la température 3 pour asservir le débit d'eau avec la température. Une description plus détaillée de cet asservissement est donnée dans la demande de brevet français n° 2 664 916 au nom de la demanderesse.As shown in Figure 1, the plate 8 has two slots 10, 11 parallel extending towards the opening 9 carrying the sleeve 17. In each slot 10, 11 is molded (see Figures 3 or 5) a slide 18, 19 These two slides 18, 19 serve to guide a slide 36 cooperating with the plug 30 and with the temperature adjustment device 3 to control the flow of water with the temperature. A more detailed description of this control is given in French patent application No. 2,664,916 in the name of the applicant.

A côté de la fente 11 est ménagé un trou 37 dans lequel est surmoulé un palier recevant l'axe 38a d'un pignon 38 rotatif pouvant s'engrener avec une crémaillère 39 ménagée sur le tiroir 36. Cet axe 38a du pignon 38 peut coopérer avec le dispositif 3 de réglage de la température. Ainsi lorsque l'utilisateur déplace le tiroir 36, il fait tourner le pignon 38 et modifie le réglage du dispositif 3 de réglage de la température. Le déplacement du tiroir 36 dont l'extrémité 40 s'engage dans une ouverture 41 du manchon 17, détermine la position du boisseau 30 qui règle le débit d'admission d'eau dans la chambre de vaporisation. Le boisseau 30 coopère avec une came 42 qui est engagée sur un doigt 43 fixe par rapport au manchon surmoulé 17 et reliée à un doigt 44 du boisseau 30.Next to the slot 11 is formed a hole 37 in which is molded a bearing receiving the axis 38a of a rotary pinion 38 which can mesh with a rack 39 formed on the drawer 36. This axis 38a of the pinion 38 can cooperate with the device 3 for adjusting the temperature. Thus when the user moves the drawer 36, he rotates the pinion 38 and modifies the setting of the device 3 for adjusting the temperature. The displacement of the drawer 36, the end 40 of which engages in an opening 41 of the sleeve 17, determines the position of the plug 30 which regulates the flow of water admission into the vaporization chamber. The plug 30 cooperates with a cam 42 which is engaged on a finger 43 fixed relative to the molded sleeve 17 and connected to a finger 44 of the plug 30.

Par ailleurs, la plaque porte sur son côté 8b, trois bandes métalliques 13, 14, 15 dont les extrémités 13a, 14a, 15a opposées à la plaque 8 sont repliées et conformées pour recevoir une cosse de connexion électrique. Ces trois bandes métalliques 13, 14, 15 sont reliées les unes aux autres par une barrette 22 en matière plastique surmoulée sur ces bandes et les isolant électriquement les unes par rapport aux autres.Furthermore, the plate carries on its side 8b, three metal strips 13, 14, 15 whose ends 13a, 14a, 15a opposite the plate 8 are folded and shaped to receive an electrical connection terminal. These three metal strips 13, 14, 15 are connected to each other by a bar 22 of plastic material overmolded on these strips and electrically insulating them from each other.

La platine comporte également une quatrième bande métallique 16 libre par rapport aux trois autres dont l'une des extrémités 17a est également repliée et conformée pour recevoir une cosse de connexion électrique.The plate also includes a fourth metal strip 16 which is free relative to the other three, one of the ends 17a of which is also folded back and shaped to receive an electrical connection terminal.

L'autre extrémité de cette bande 16 comporte un trou 45 dans lequel est surmoulée une rondelle isolante 46 permettant sa fixation au thermostat de réglage de la température du fer.The other end of this strip 16 has a hole 45 in which an insulating washer 46 is overmolded allowing it to be fixed to the thermostat for adjusting the temperature of the iron.

La plaque 8 comporte sur sa périphérie des pattes 5, 6, 7 repliées pourvues chacune d'un trou 12 permettant le passage d'un moyen de fixation.The plate 8 has on its periphery folded tabs 5, 6, 7 each provided with a hole 12 allowing the passage of a fixing means.

La figure 6 représente une semelle chauffante 50 du fer à repasser sur le dessus de laquelle la platine 1 peut être fixée grâce aux pattes 5, 6, 7 et trous de fixation de ceux-ci.FIG. 6 represents a heating soleplate 50 of the iron on top of which the plate 1 can be fixed by means of the tabs 5, 6, 7 and fixing holes thereof.

Les bandes métalliques de connexion 13, 14, 15 font saillie sur le côté 8b de la platine 8 adjacent à la partie arrière 51 de la semelle 50 où sortent les extrémités 52 de la résistance électrique de chauffage. Les bandes métalliques de connexion 13 et 15 sont reliées électriquement (voir pointillées 53, 54) auxdites extrémités de la résistance électrique.The metal connection strips 13, 14, 15 protrude on the side 8b of the plate 8 adjacent to the rear part 51 of the sole 50 where the ends 52 of the electrical heating resistance come out. The metallic connection strips 13 and 15 are electrically connected (see dotted lines 53, 54) to said ends of the electrical resistance.

Les principaux avantages de la platine fonctionnelle que l'on vient de décrire sont les suivants:

  • Le fait que cette platine soit réalisée à partir d'une feuille d'acier découpée et par surmoulage d'éléments en matière plastique permet d'obtenir une platine à faible coût.
The main advantages of the functional stage which have just been described are the following:
  • The fact that this plate is produced from a cut steel sheet and by overmolding of plastic elements makes it possible to obtain a plate at low cost.

La base métallique de cette platine confère à celle-ci une bonne résistance mécanique et une bonne tenue à la température, compte tenu de la proximité de la résistance chauffante de la semelle.The metal base of this plate gives it good mechanical resistance and good temperature resistance, given the proximity of the heating resistance of the sole.

D'autre part, l'utilisation d'une base métallique permet de réaliser directement dans celle-ci, par découpage et pliage, des bandes conductrices permettant les connexions électriques.On the other hand, the use of a metal base makes it possible to produce directly in the latter, by cutting and folding, conductive strips allowing the electrical connections.

Les isolations électriques nécessaires à cet effet peuvent être effectuées sans difficulté et en même temps que le surmoulage des autres éléments fonctionnels de la platine.The electrical insulations necessary for this purpose can be carried out without difficulty and at the same time as the overmolding of the other functional elements of the plate.

Ces isolations électriques participent à la rigidité de l'ensemble de la platine et permettent ainsi d'obtenir un ensemble pratiquement d'une seule pièce pouvant être fixé directement sur le dessus de la semelle au moyen de quelques vis par exemple.These electrical insulations participate in the rigidity of the whole of the plate and thus make it possible to obtain an assembly practically in one piece which can be fixed directly on the top of the sole by means of a few screws for example.

Une fois que la platine est fixée sur la semelle, il suffit d'établir quelques connexions électriques.Once the plate is fixed on the sole, it is enough to establish some electrical connections.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and many modifications can be made to it without departing from the scope of the invention.
