Description

La présente invention concerne un dispositif de repassage à vapeur, comportant :

  • un fer à repasser électrique comprenant une semelle chauffante et une chambre de vaporisation pratiquée dans la semelle, fermée par un couvercle métallique et communiquant avec l'extérieur au moyen d'orifices de sortie de vapeur ménagés dans la semelle ;
  • un générateur de vapeur indépendant ; et
  • un tuyau souple d'amenée de vapeur dont une extrémité est branchée en sortie du générateur de vapeur et dont l'autre extrémité est reliée à la chambre de vaporisation du fer à repasser par un conduit de vapeur logé dans ledit fer.
The present invention relates to a steam ironing device, comprising:
  • an electric iron comprising a heated soleplate and a vaporization chamber formed in the soleplate, closed by a metal cover and communicating with the outside by means of steam outlet orifices provided in the soleplate;
  • an independent steam generator; and
  • a flexible steam supply pipe, one end of which is connected to the outlet of the steam generator and the other end of which is connected to the steam chamber of the iron by a steam pipe housed in said iron.

On connaît déjà différents types classiques de fers à repasser électriques à vapeur, à usage domestique, comportant notamment une semelle métallique chauffante fermée par un couvercle, une calotte chapeautant la semelle et isolant thermiquement celle-ci de la carrosserie du fer, un réservoir d'eau et une chambre de vaporisation pratiquée dans la semelle et dans laquelle est produite une certaine quantité de vapeur d'eau sous pression projetée à travers des orifices de sortie ménagés dans la semelle du fer à repasser. L'eau, contenue dans le réservoir, est dirigée par un dispositif d'injection soumis à actionnement, vers la chambre de vaporisation chauffée par une résistance électrique noyée dans la semelle du fer. Au contact du métal chauffé, l'eau est transformée en vapeur et s'échappe par les orifices de sortie ménagés à cet effet.Various conventional types of electric steam irons are already known for domestic use, comprising in particular a heated metal soleplate closed by a cover, a cap covering the soleplate and thermally insulating the latter from the body of the iron, a reservoir for water and a vaporization chamber formed in the soleplate and in which a certain quantity of pressurized steam is produced projected through outlet orifices provided in the soleplate of the iron. The water, contained in the tank, is directed by an injection device subjected to actuation, towards the vaporization chamber heated by an electrical resistance embedded in the soleplate of the iron. On contact with the heated metal, the water is transformed into vapor and escapes through the outlet ports provided for this purpose.

Ce type de fer à repasser à vapeur fonctionnant de manière autonome donne entière satisfaction.This type of steam iron operating independently gives complete satisfaction.

Cependant, actuellement, on utilise de plus en plus pour une production importante de vapeur sous pression, un générateur de vapeur d'eau qui est structurellement indépendant d'un fer à repasser, et qui est relié à l'arrière du fer à repasser par un tuyau souple d'amenée de vapeur.However, today, more and more is used for a large production of pressurized steam, a steam generator which is structurally independent of an iron, and which is connected to the rear of the iron by a flexible steam supply pipe.

Dans ce type d'installation de repassage, il est souhaitable d'utiliser un fer à repasser qui existe déjà sur le marché, tel que celui décrit précédemment et pour lequel le dispositif d'injection d'eau est bien entendu hors service. On a alors proposé de relier le tuyau souple à la chambre de vaporisation du fer à repasser au moyen d'un conduit de vapeur souple et isolant, en faisant passer ce dernier soit au-dessous de la calotte d'isolation thermique dudit fer en le raccordant au tuyau souple par des pièces intermédiaires isolantes, d'où une certaine complexité de raccordement, et en le branchant directement à la chambre de vaporisation du fer à repasser, d'où un montage relativement difficile du conduit en raison de sa souplesse, soit au-dessus de la calotte d'isolation thermique ce qui nécessite inévitablement de profondes modifications du fer à repasser en question, voire une nouvelle conception spécifique du fer à repasser.In this type of ironing installation, it is desirable to use an iron which already exists on the market, such as that described above and for which the water injection device is of course out of service. It has then been proposed to connect the flexible pipe to the vaporization chamber of the iron by means of a flexible and insulating steam conduit, by passing the latter either below the thermal insulation cap of said iron by connecting to the flexible pipe by insulating intermediate parts, hence a certain complexity of connection, and by connecting it directly to the steam chamber of the iron, hence a relatively difficult assembly of the duct due to its flexibility, or above the thermal insulation cap, which inevitably necessitates major modifications to the iron in question, or even a new specific design of the iron.

De plus, le conduit de vapeur utilisé est en général réalisé en un silicone qui est relativement sujet à une déformation avec l'usage du fer à repasser, un tel conduit risquant par ailleurs de se débrancher, notamment au niveau de la chambre de vaporisation du fer, sous l'action de la pression de la vapeur véhiculée.In addition, the vapor conduit used is generally made of a silicone which is relatively subject to deformation with the use of the iron, such a conduit also running the risk of being disconnected, in particular at the level of the vaporization chamber of the iron, under the action of the pressure of the conveyed vapor.

L'invention a pour but de pallier ces inconvénients et de réaliser un dispositif de repassage à vapeur, du type exposé ci-dessus, mettant en oeuvre une liaison entre le tuyau souple d'amenée de vapeur et la chambre de vaporisation d'un fer à repasser, qui soit simple, fiable, économique et facile à établir, et qui puisse aisément s'adapter sur un fer à repasser de constitution classique connue, c'est-à-dire conçu pour fonctionner en autonomie.The object of the invention is to overcome these drawbacks and to produce a steam ironing device, of the type described above, using a connection between the flexible steam supply pipe and the vaporization chamber of an iron, which is simple, reliable, economical and easy to set up, and which can easily be adapted to an iron of known conventional constitution , that is to say designed to operate independently.

Selon l'invention, le conduit de vapeur assurant la liaison entre le tuyau souple d'amenée de vapeur et la chambre de vaporisation du fer à repasser est un tube métallique rigide dont une extrémité dite arrière est directement raccordée au tuyau souple et dont l'autre extrémité dite avant débouche dans la chambre de vaporisation du fer à repasser en étant encastrée de façon étanche dans une ouverture percée dans le couvercle de la chambre de vaporisation dudit fer.According to the invention, the steam conduit ensuring the connection between the flexible steam supply pipe and the steam chamber of the iron is a rigid metal tube, one so-called rear end is directly connected to the flexible pipe and the another so-called front end opens into the steam chamber of the iron, being sealed in an opening pierced in the cover of the steam chamber of said iron.

Ainsi, on obtient une liaison tuyau souple - chambre de vaporisation du fer à repasser, qui est à la fois simple à réaliser et fiable dans le temps puisqu'elle ne fait intervenir qu'un seul tube métallique rigide de conduite de vapeur. Une telle simplicité de montage est bien adaptée à une fabrication automatique en grande série.Thus, one obtains a flexible pipe - steam chamber connection of the iron, which is both simple to perform and reliable over time since it only involves a single rigid metal tube for conducting the steam. Such simplicity of assembly is well suited to automatic mass production.

D'autres caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre d'un mode particulier de réalisation pris à titre d'exemple non limitatif illustré aux dessins annexés dans lesquels :

  • la figure 4 est une vue schématique de dessus de l'ensemble semelle-tube du fer à repasser de la figure 1, avec représentation des liaisons électriques du fer.
Other characteristics and advantages of the invention will emerge from the description which follows of a particular embodiment taken by way of nonlimiting example illustrated in the appended drawings in which:
  • Figure 1 is a schematic partial sectional view of the steam ironing device according to the invention;
  • Figure 2 is an exploded perspective view of certain components, shown in cross section, of the lower part of the iron illustrated in Figure 1;
  • Figure 3 is a cross-sectional view of the components of Figure 2 once assembled; and
  • Figure 4 is a schematic top view of the sole-tube assembly of the iron of Figure 1, with representation of the electrical connections of the iron.

En référence à la figure 1, un dispositif de repassage à vapeur comporte un fer à repasser 1, un générateur de vapeur indépendant 2 et un tuyau souple 3 d'amenée de vapeur, reliant le générateur de vapeur au fer à repasser.With reference to FIG. 1, a steam ironing device comprises an iron 1, an independent steam generator 2 and a flexible pipe 3 for supplying steam, connecting the steam generator to the iron.

Le générateur de vapeur 2, destiné à produire une grande quantité de vapeur d'eau sous pression, est d'une structure connue en soi. A titre purement indicatif, ce générateur de vapeur est par exemple du type comportant :

  • soit un réservoir prévu pour contenir une quantité déterminée d'eau et de vapeur produite à partir de cette eau, et une résistance plongeante pour chauffer l'eau et engendrer cette vapeur,
  • soit une chaudière alimentée en eau contenue dans un réservoir séparé via une micropompe.
The steam generator 2, intended to produce a large quantity of pressurized water vapor, is of a structure known per se. For purely indicative purposes, this steam generator is for example of the type comprising:
  • either a tank intended to contain a determined quantity of water and of steam produced from this water, and a plunging resistance to heat the water and generate this steam,
  • or a boiler supplied with water contained in a separate tank via a micropump.

En regard des figures 1 et 2, le fer à repasser 1 (figure 1) comporte un sous-ensemble (semelle) désigné par le repère général 4 sur la figure 2 et comprenant une semelle métallique moulée 5, par exemple en aluminium, dans laquelle est pratiquée une chambre de vaporisation 6 qui communique avec l'extérieur au moyen d'orifices de sortie 7 ménagés dans la face inférieure de la semelle 5.With reference to FIGS. 1 and 2, the iron 1 (FIG. 1) comprises a sub-assembly (sole) designated by the general reference 4 in FIG. 2 and comprising a molded metal sole 5, for example made of aluminum, in which a vaporization chamber 6 is formed which communicates with the outside by means of outlet orifices 7 formed in the underside of the sole 5.

La chambre de vaporisation 6 est fermée par un couvercle 8 en tôle emboutie. A cet effet, le couvercle 8 présente un bord périphérique courbé 9 qui est encastré dans une rainure complémentaire 10 pratiquée dans la face supérieure de la semelle 5. Le couvercle 8 est de plus maintenu sur la semelle 5 au moyen d'éléments de serrage (non figurés).The vaporization chamber 6 is closed by a cover 8 of pressed sheet metal. For this purpose, the cover 8 has a curved peripheral edge 9 which is embedded in a complementary groove 10 formed in the upper face of the sole 5. The cover 8 is moreover held on the sole 5 by means of clamping elements (not shown).

Dans la semelle 5 est noyée une résistance électrique blindée 12 en forme de U dont seules les deux extrémités 12a, 12b sont visibles sur la figure 4.In the sole 5 is embedded a shielded electrical resistance 12 in the shape of a U of which only the two ends 12a, 12b are visible in FIG. 4.

Le sous-ensemble 4, figure 2, comprend également une plaque 13 en tôle, de section droite en forme de Z, qui est disposée fixement sur la face supérieure de la semelle 5, en surplomb relativement à l'extrémité arrière de cette dernière, et qui supporte de façon solidaire un conducteur de terre 14 coudé verticalement vers le haut.The sub-assembly 4, FIG. 2, also includes a sheet metal plate 13, of Z-shaped cross section, which is fixedly disposed on the upper face of the sole 5, overhanging relative to the rear end of the latter, and which integrally supports an earth conductor 14 bent vertically upwards.

Conformément à l'invention, le tuyau souple 3, figure 1, branché en sortie du générateur de vapeur 2 et entrant dans la partie arrière 15 du fer à repasser 1, est relié à la chambre de vaporisation 6 dudit fer par un seul tube métallique rigide 16 de conduite de vapeur, réalisé par exemple en aluminium, dont une extrémité dite arrière 17 est directement raccordée au tuyau souple 3 et dont l'autre extrémité dite avant 18 débouche dans la chambre de vaporisation 6 du fer en étant encastrée de façon étanche dans une ouverture 19 percée dans le couvercle 8 de la chambre de vaporisation 6 du fer à repasser.According to the invention, the flexible pipe 3, FIG. 1, connected at the outlet of the steam generator 2 and entering the rear part 15 of the iron 1, is connected to the vaporization chamber 6 of said iron by a single metal tube rigid steam pipe 16, made for example of aluminum, one end of which is said to be rear 17 is directly connected to the flexible pipe 3 and the other end of which is known as front 18 opens into the vaporization chamber 6 of the iron, being sealed in an opening 19 pierced in the cover 8 of the vaporization chamber 6 of the iron.

Dans l'exemple de réalisation illustré à la figure 1, l'extrémité arrière 17 du tube 16 comporte un bourrelet annulaire 20 sur lequel est emmanché à force le tuyau 3, l'ensemble étant fermement maintenu en place par exemple au moyen d'un ruban de cerclage approprié 21.In the embodiment illustrated in FIG. 1, the rear end 17 of the tube 16 comprises an annular bead 20 on which the tube 3 is force fitted, the assembly being firmly held in place for example by means of a suitable strapping tape 21.

Dans cet exemple, figure 1, l'extrémité avant 18 du tube 16 est emmanchée à force dans un joint tubulaire souple d'étanchéité 22 réalisé en un élastomère, de préférence un silicone, et monté sans jeu dans l'ouverture 19 d'entrée dans la chambre de vaporisation 6 du fer à repasser 1 afin d'empêcher toute fuite de vapeur.In this example, FIG. 1, the front end 18 of the tube 16 is force fitted into a flexible tubular sealing joint 22 made of an elastomer, preferably a silicone, and mounted without play in the inlet opening 19 in the vaporization chamber 6 of the iron 1 in order to prevent any vapor leakage.

On notera qu'une fois le joint souple 22 inséré dans l'ouverture 19, l'emmanchement à force de l'extrémité avant du tube 16 dans ledit joint provoque une expansion radiale de ce dernier, assurant ainsi un parfait serrage du joint dans l'ouverture 19 et partant, une excellente étanchéité.It will be noted that once the flexible seal 22 is inserted into the opening 19, the force fitting of the front end of the tube 16 into said seal causes the latter to expand radially, thus ensuring perfect tightening of the seal in the opening 19 and therefore an excellent seal.

En regard des figures 1 et 2, le joint tubulaire d'étanchéité 22 est constitué présentement par une collerette cylindrique 23, à entrée conique (voir figure 2), qui est appliquée à plat contre le couvercle 8 et qui se prolonge axialement par une queue ou embout cylindrique 24 faisant saillie dans la chambre de vaporisation 6 et pourvu d'un bourrelet 25 se clipsant derrière un soyé cylindrique 26 (figure 2) pratiqué dans l'ouverture 19 du couvercle 8 et venu d'emboutissage.With reference to FIGS. 1 and 2, the tubular seal 22 is presently constituted by a cylindrical flange 23, with a conical inlet (see FIG. 2), which is applied flat against the cover 8 and which is extended axially by a shank. or cylindrical end piece 24 projecting into the vaporization chamber 6 and provided with a bead 25 clipping behind a cylindrical groove 26 (FIG. 2) formed in the opening 19 of the cover 8 and coming from stamping.

Le tube métallique 16 est de préférence préformé et présente une partie avant 16a en forme de col de cygne dont la partie antérieure 28 (figure 2) s'étend verticalement dans le joint 22 sur toute la hauteur de ce dernier, et dont la partie postérieure 29 (figure 2) a un tronçon d'extrémité 30, opposé au coude 27 du col de cygne, qui est en appui contre le couvercle 8 de la chambre de vaporisation 6, comme bien visible aux figures 1 et 3. Ce tronçon d'extrémité 30 de la partie postérieure 29 du col de cygne est éventuellement maintenu en appui contre le couvercle 8 au moyen d'un élément de serrage, tel que par exemple un ruban adhésif (non figuré).The metal tube 16 is preferably preformed and has a front part 16a in the form of a swan neck, the front part 28 (FIG. 2) of which extends vertically in the joint 22 over the entire height of the latter, and the rear part of which 29 (Figure 2) has an end section 30, opposite the bend 27 of the swan neck, which is supported against the cover 8 of the vaporization chamber 6, as clearly visible in Figures 1 and 3. This section of end 30 of the rear part 29 of the swan neck is optionally held in abutment against the cover 8 by means of a clamping element, such as for example an adhesive tape (not shown).

On indiquera que le fait de conformer la partie avant 16a du tube 16 en un col de cygne permet, grâce à son tronçon d'extrémité 30 en appui contre le couvercle 8, de limiter la hauteur d'emmanchement du tube dans le joint en garantissant une distance déterminée d entre le débouché de l'extrémité avant 18 du tube et le fond de la chambre de vaporisation 6 du fer à repasser, voir figures 1 et 3.It will be indicated that the fact of conforming the front part 16a of the tube 16 into a swan neck makes it possible, thanks to its end section 30 bearing against the cover 8, to limit the height of fitting of the tube in the joint while guaranteeing a determined distance d between the outlet of the front end 18 of the tube and the bottom of the steam chamber 6 of the iron, see FIGS. 1 and 3.

A partir de la partie postérieure 29 de sa conformation en col de cygne, le tube 16 présente une partie intermédiaire 16b dirigée vers l'arrière du fer à repasser et disposée partiellement en appui, sur une première portion, contre le couvercle 8 de la chambre de vaporisation 6, et sur une seconde portion, contre la plaque 13 de la semelle 5 (voir figure 4), ainsi qu'une partie arrière 16c prolongeant la partie intermédiaire 16b, coudée verticalement vers le haut et raccordée au tuyau souple 3, comme on le voit sur la figure 1.From the rear part 29 of its swan neck conformation, the tube 16 has an intermediate part 16b directed towards the rear of the iron and disposed partially in abutment, on a first portion, against the cover 8 of the chamber spray 6, and on a second portion, against the plate 13 of the sole 5 (see FIG. 4), as well as a rear part 16c extending the intermediate part 16b, bent vertically upwards and connected to the flexible pipe 3, as seen in Figure 1.

Il convient de noter que le tube 16, en contact avec le couvercle 8 solidaire de la semelle 5, est lui-même chauffé par la résistance électrique 12 et partant, contribue à éliminer d'éventuelles gouttes d'eau qui sont entraînées par la vapeur produite par le générateur 2 et qui sont susceptibles de pénétrer dans la chambre de vaporisation 6 du fer à repasser où elles sont définitivement vaporisées, la vapeur s'échappant alors par les orifices de sortie 7. La présence de ces gouttes d'eau entraînées par la vapeur est notamment due à une condensation de la vapeur dans le tuyau souple de liaison 3. Leur élimination par chauffage du tube 16 est d'autant plus efficace que le tube 16 est de grande longueur, de petite section et possède des chicanes.It should be noted that the tube 16, in contact with the cover 8 secured to the sole 5, is itself heated by the electrical resistance 12 and therefore contributes to eliminating any drops of water which are entrained by the steam. produced by the generator 2 and which are capable of entering the vaporization chamber 6 of the iron where they are definitively vaporized, the vapor then escaping through the outlet orifices 7. The presence of these drops of water entrained by the vapor is notably due to a condensation of the vapor in the flexible connecting pipe 3. Their elimination by heating the tube 16 is all the more effective as the tube 16 is of great length, of small section and has baffles.

Il convient également de signaler ici que le fer à repasser 1 n'est jamais soumis au problème connu d'entartrage car le calcaire se dépose entièrement dans le générateur 2, de sorte que les éventuelles gouttes d'eau entraînées dans le tuyau 3 et le tube 16 par la vapeur produite par le générateur 2 sont des gouttes d'eau déminéralisée.It should also be noted here that the iron 1 is never subject to the known problem of scaling because the lime deposits entirely in the generator 2, so that any drops of water entrained in the pipe 3 and the tube 16 by the steam produced by the generator 2 are drops of demineralized water.

En regard des figures 1 et 2, le fer à repasser 1 (figure 1) comporte également une calotte d'isolation thermique 32 réalisée par moulage en une matière isolante et destinée à venir se fixer sur la semelle 5 du fer à repasser par exemple au moyen de vis telles qu'illustrées en 33 sur la figure 1. Cette calotte 32 présente un orifice de guidage 34 qui est traversé par la partie arrière verticale coudée 16c du tube 16 et qui possède une nervure interne verticale 35, venue de moulage, et appliquée contre cette partie arrière coudée 16c du tube, sensiblement au niveau du coude de celle-ci, de manière à maintenir en place la partie arrière 16c du tube 16 contre la plaque 13 solidaire de la semelle 5.With reference to FIGS. 1 and 2, the iron 1 (FIG. 1) also includes a thermal insulation cap 32 produced by molding in an insulating material and intended to be fixed on the sole plate 5 of the iron, for example at means of screws as illustrated at 33 in FIG. 1. This cap 32 has a guide orifice 34 which is traversed by the bent vertical rear part 16c of the tube 16 and which has a vertical internal rib 35, coming from molding, and applied against this bent rear part 16c of the tube, substantially at the elbow thereof, so as to hold in place the rear part 16c of the tube 16 against the plate 13 secured to the sole 5.

La calotte 32 présente également une ouverture 36 au travers de laquelle passe le conducteur de terre coudé 14. Le tube 16, au niveau de sa partie arrière 16c, est de préférence relié électriquement au conducteur de terre 14.The cap 32 also has an opening 36 through which the bent earth conductor 14 passes. The tube 16, at its rear part 16c, is preferably electrically connected to the earth conductor 14.

Comme on le voit sur la figure 1, le tube 16 est donc en quasi-totalité agencé en dessous de la calotte d'isolation thermique 32, moyennant un léger jeu j au niveau de sa partie avant 16a en col de cygne.As seen in Figure 1, the tube 16 is therefore almost entirely arranged below the thermal insulation cap 32, with a slight clearance j at its front part 16a swan neck.

En regard de la figure 2, après réalisation du sous-ensemble 4 (semelle) du fer à repasser, le joint d'étanchéité 22 est alors monté serré dans l'ouverture 19 du couvercle 8, puis la partie avant 16a en col de cygne du tube 16 est emmanchée à force dans le joint 22 et la calotte 32 est rapportée sur le sous-ensemble 4 avec passage en saillie, d'une part, de la partie arrière coudée 16c du tube 16 au travers de l'orifice 34 et, d'autre part, du conducteur de terre 14 au travers de l'ouverture 36.With reference to FIG. 2, after completion of the sub-assembly 4 (sole) of the iron, the seal 22 is then mounted tightly in the opening 19 of the cover 8, then the front part 16a in the swan neck of the tube 16 is force fitted into the seal 22 and the cap 32 is attached to the sub-assembly 4 with projecting passage, on the one hand, from the rear part bent 16c of the tube 16 through the orifice 34 and, on the other hand, of the earth conductor 14 through the opening 36.

La figure 3 montre un tel assemblage ou montage qui est donc aisé et rapide à exécuter, sans risque d'erreurs, et ce de façon manuelle ou de préférence automatisée. Après ce montage, le tuyau souple 3 (représenté en traits interrompus sur la figure 3) est directement raccordé sur l'extrémité arrière 17 du tube 16.FIG. 3 shows such an assembly or mounting which is therefore easy and quick to execute, without risk of errors, and this in a manual or preferably automated manner. After this assembly, the flexible hose 3 (shown in broken lines in FIG. 3) is directly connected to the rear end 17 of the tube 16.

On a désigné par 37 sur la figure 1 un câble ou cordon électrique destiné à assurer l'alimentation électrique du fer à repasser 1 et entrant, comme le tuyau souple 3, dans la partie arrière 15 du fer à repasser.There is designated by 37 in Figure 1 an electric cable or cord intended to ensure the electrical supply of the iron 1 and entering, like the flexible pipe 3, in the rear part 15 of the iron.

Les fils électriques (non figurés) du cordon 37 sont reliés respectivement à des conducteurs électriques désignés en 38 sur la figure 4. Comme on le voit sur cette figure 4, le tube 16 s'étend à distance appropriée de ces conducteurs électriques 38.The electrical wires (not shown) of the cord 37 are respectively connected to electrical conductors designated at 38 in FIG. 4. As can be seen in this FIG. 4, the tube 16 extends at an appropriate distance from these electrical conductors 38.

Selon la figure 1, le fer à repasser 1 comporte un capot de protection 39 formant corps avec une poignée creuse 40 et rapporté sur la calotte d'isolation thermique 32.According to FIG. 1, the iron 1 comprises a protective cover 39 forming a body with a hollow handle 40 and attached to the thermal insulation cap 32.

De plus, le fer à repasser utilisé 1 (figure 1) est conçu de façon classique pour fonctionner en autonomie, donc sans générateur de vapeur indépendant, et fait intervenir à cet égard :

  • une réserve à eau 41 délimitée par la calotte 32 et une partie du capot 39 ;
  • un dispositif commandé d'injection d'eau 42 adapté pour alimenter en eau la chambre de vaporisation 6 au travers d'une ouverture 43 pratiquée dans le couvercle 8 et rendue étanche au moyen d'un joint 44, l'eau étant vaporisée dans la chambre 6 grâce à la chaleur de la résistance électrique 12 et la vapeur ainsi produite sortant par les orifices 7 ;
  • un dispositif commandé de pulvérisation d'eau 45 agencé en saillie hors du capot 39 ;
  • un dispositif 46 de commande de thermorégulateur.
In addition, the iron used 1 (FIG. 1) is conventionally designed to operate independently, therefore without an independent steam generator, and involves in this regard:
  • a water reserve 41 delimited by the cap 32 and part of the cover 39;
  • a controlled water injection device 42 suitable for supplying water to the vaporization chamber 6 through an opening 43 formed in the cover 8 and sealed by means of a seal 44, the water being vaporized in the chamber 6 thanks to the heat of the electrical resistance 12 and the steam thus produced leaving through the orifices 7;
  • a controlled device for spraying water 45 arranged projecting from the cover 39;
  • a thermoregulator control device 46.

Evidemment, un tel fer à repasser 1, lorsqu'il est utilisé avec le générateur de vapeur extérieur 2, est adapté de manière à ce que son dispositif d'injection 42 soit mis hors service.Obviously, such an iron 1, when used with the external steam generator 2, is adapted so that its injection device 42 is put out of service.

On indiquera, comme le montre d'ailleurs la figure 4, que l'ouverture 19 est de préférence décalée par rapport à l'ouverture 43 qui est pratiquée sur l'axe longitudinal XX de la semelle 5 du fer à repasser.It will be indicated, as also shown in Figure 4, that the opening 19 is preferably offset from the opening 43 which is formed on the longitudinal axis XX of the sole 5 of the iron.

Ainsi, suivant l'invention, on a réalisé une adaptation simple mais efficace d'un fer à repasser à vapeur de type classique dans le but de pouvoir l'utiliser avec un générateur de vapeur indépendant, ce qui entre autres est particulièrement intéressant sur le plan du coût de fabrication de l'ensemble.Thus, according to the invention, a simple but effective adaptation has been made of a conventional type steam iron in order to be able to use it with an independent steam generator, which among other things is particularly advantageous in plan of the manufacturing cost of the assembly.
