Description

La présente invention concerne un fer à repasser électrique à vapeur perfectionné.The present invention relates to an improved electric steam iron.

Les fers à repasser à vapeur connus comprennent une semelle chauffante comportant une résistance électrique de chauffage, un réservoir d'eau, une chambre de vaporisation, et un dispositif d'alimentation en eau de la chambre de vaporisation. Cet ensemble est coiffé par une carrosserie de protection dans laquelle est généralement incorporée une poignée de préhension du fer.Known steam irons include a heating soleplate comprising an electrical heating resistor, a water tank, a vaporization chamber, and a device for supplying water to the vaporization chamber. This assembly is capped by a protective bodywork in which is generally incorporated a handle for gripping the iron.

Dans la demande de brevet français n° 89 07580 du 8 juin 1989 au nom de la demanderesse, cette dernière a présenté un fer à repasser du type ci-dessus qui, outre les organes précités, comporte une cartouche déminéralisante qui est placée dans le circuit d'eau qui relie le réservoir à la chambre de vaporisation.In French patent application No. 89 07580 of June 8, 1989 in the name of the plaintiff, the latter presented an iron of the above type which, in addition to the aforementioned organs, includes a demineralizing cartridge which is placed in the circuit of water which connects the tank to the vaporization chamber.

Cette cartouche est remplie d'une résine échangeuse d'ions qui a pour effet d'enlever de l'eau les éléments tels que le calcaire qui sont responsables de l'entartrage de la chambre de vaporisation et des ouvertures de sortie de la vapeur pratiquées dans la semelle du fer.This cartridge is filled with an ion exchange resin which has the effect of removing from the water the elements such as limestone which are responsible for the scaling of the vaporization chamber and the steam outlet openings made. in the soleplate of the iron.

D'autre part, le caractère amovible de cette cartouche pose un problème d'étanchéité entre le réservoir et le conduit communiquant avec le dispositif d'alimentation de la chambre de vaporisation.On the other hand, the removable nature of this cartridge poses a sealing problem between the reservoir and the conduit communicating with the device for supplying the vaporization chamber.

Le but de la présente invention est d'apporter des perfectionnements au fer à vapeur décrit dans la demande de brevet français précitée.The object of the present invention is to provide improvements to the steam iron described in the aforementioned French patent application.

L'invention vise ainsi un fer à repasser électrique à vapeur comprenant une semelle chauffante, une chambre de vaporisation, un réservoir d'eau, un dispositif d'alimentation en eau de la chambre de vaporisation, une cartouche déminéralisante placée dans le circuit d'eau qui relie le réservoir à la chambre de vaporisation, l'ensemble étant coiffé par une carrosserie de protection.The invention thus relates to an electric steam iron comprising a heating soleplate, a vaporization chamber, a water tank, a device for supplying water to the vaporization chamber, a demineralizing cartridge placed in the circuit of water which connects the tank to the vaporization chamber, the assembly being capped by a protective bodywork.

Suivant l'invention, ce fer à repasser est caractérisé en ce que la cartouche déminéralisante est disposée de façon amovible entre un réservoir primaire d'eau brute et un réservoir secondaire d'eau déminéralisée qui communique avec le dispositif d'alimentation d'eau, la cartouche communiquant avec le réservoir primaire et le réservoir secondaire au moyen de clapets évitant l'écoulement de l'eau, lorsque cette cartouche est retirée du fer.According to the invention, this iron is characterized in that the demineralizing cartridge is removably disposed between a primary tank of raw water and a secondary tank of demineralized water which communicates with the water supply device, the cartridge communicating with the primary reservoir and the secondary reservoir by means of valves preventing the flow of water, when this cartridge is removed from the iron.

Ainsi, la cartouche sépare physiquement deux réservoirs qui contiennent l'une de l'eau brute et l'autre de l'eau déminéralisée. Les clapets permettent d'enlever la cartouche pour son remplacement par une cartouche neuve, sans écoulement d'eau de l'un des réservoirs.Thus, the cartridge physically separates two reservoirs which contain one of raw water and the other of demineralized water. The valves allow the cartridge to be removed for replacement with a new cartridge, without water flowing from one of the tanks.

Selon une version avantageuse de l'invention, la partie arrière de la carrosserie du fer est prolongée au-delà du bord arrière de la semelle, la cartouche déminéralisante étant logée dans ladite partie arrière, et située à une distance suffisante de la semelle pour éviter tout échauffement de cette cartouche.According to an advantageous version of the invention, the rear part of the body of the iron is extended beyond the rear edge of the sole, the demineralizing cartridge being housed in said rear part, and located at a sufficient distance from the sole to avoid any heating of this cartridge.

La résine échangeuse d'ions contenue dans la cartouche déminéralisante ne supporte pas une température très élevée et notamment pas l'échauffement provoqué par la semelle chauffante et la paroi de la chambre de vaporisation.The ion exchange resin contained in the demineralizing cartridge does not withstand a very high temperature and in particular not the heating caused by the heating soleplate and the wall of the vaporization chamber.

Grâce à la disposition de la cartouche dans une partie arrière du fer située au-delà du bord arrière de la semelle, elle est suffisamment éloignée de celle-ci pour éviter tout échauffement susceptible de rendre la résine inactive.Thanks to the arrangement of the cartridge in a rear part of the iron situated beyond the rear edge of the soleplate, it is sufficiently distant from the latter to avoid any heating which could render the resin inactive.

Cette disposition n'était pas évidente à trouver dans le cas d'un fer à vapeur.This provision was not obvious to find in the case of a steam iron.

Selon une version avantageuse de l'invention, la cartouche déminéralisante est disposée de façon amovible dans un logement qui est relié au réservoir d'eau.According to an advantageous version of the invention, the demineralizing cartridge is arranged so removable in a housing which is connected to the water tank.

Cette liaison entre le logement de la cartouche et le réservoir implique une condition d'échange thermique entre le réservoir qui contient de l'eau froide (elle provient du robinet) et la cartouche, ce qui contribue au maintien à basse température de la résine contenue dans la cartouche.This connection between the cartridge housing and the reservoir implies a heat exchange condition between the reservoir which contains cold water (it comes from the tap) and the cartridge, which contributes to keeping the resin contained at low temperature. in the cartridge.

De préférence, le réservoir d'eau s'étend sensiblement parallèlement à la semelle chauffante et à une certaine distance au-dessus de celle-ci, le fond du logement de la cartouche étant situé sensiblement dans le prolongement de fond du réservoir.Preferably, the water tank extends substantially parallel to and at a certain distance above the heating soleplate, the bottom of the cartridge housing being located substantially in the bottom extension of the tank.

Ainsi, la disposition de la cartouche n'affecte pas l'encombrement en hauteur du fer à repasser.Thus, the arrangement of the cartridge does not affect the overall height of the iron.

Selon une version préférée de l'invention, la paroi supérieure du logement de la cartouche est adjacente à l'intérieur du réservoir d'eau.According to a preferred version of the invention, the upper wall of the cartridge housing is adjacent to the interior of the water tank.

Cette paroi du logement fait ainsi partie de la paroi du réservoir, de sorte que le logement est intégré au réservoir.This wall of the housing thus forms part of the wall of the tank, so that the housing is integrated into the tank.

De plus, cette paroi permet par échange thermique avec l'eau du réservoir, de maintenir la résine à basse température.In addition, this wall allows, by heat exchange with the water in the tank, to keep the resin at low temperature.

Selon une réalisation avantageuse de l'invention, ladite paroi supérieure est inclinée vers l'avant du fer, ladite paroi supérieure du logement étant raccordée au fond du réservoir d'eau par un pan incliné, le bord arrière du pan incliné étant relié à la paroi supérieure du logement par une cloison transversale formant avec cette paroi un réceptacle constituant une réserve d'eau.According to an advantageous embodiment of the invention, said upper wall is inclined towards the front of the iron, said upper wall of the housing being connected to the bottom of the water tank by an inclined panel, the rear edge of the inclined panel being connected to the upper wall of the housing by a transverse partition forming with this wall a receptacle constituting a water reserve.

Ce pan incliné permet une alimentation en eau de la cartouche par les "vagues" d'eau formées lors du déplacement en aller et retour du fer.This inclined pan allows a supply of water to the cartridge by the "waves" of water formed during the back and forth movement of the iron.

Les vagues ainsi formées se déversent dans le réceptacle formant réserve qui communique avec l'entrée de la cartouche.The waves thus formed flow into the receptacle forming a reserve which communicates with the inlet of the cartridge.

D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will appear in the description below.

Dans la réalisation des figures 1 à 3, le fer à repasser électrique à vapeur comprend une semelle chauffante 1 renfermant une résistance électrique 2, une chambre de vaporisation 3 fermée par une paroi métallique 4, un réservoir d'eau 5, un dispositif 6 d'alimentation en eau "goutte à goutte" de la chambre de vaporisation 3, et une cartouche déminéralisante 7 (voir figures 2, 3 et 4) placée dans le circuit d'eau qui relie le réservoir 5 à la chambre de vaporisation 3.In the embodiment of FIGS. 1 to 3, the electric steam iron comprises a heating sole 1 containing an electrical resistance 2, a vaporization chamber 3 closed by a metal wall 4, a water tank 5, a device 6 d water supply "drop by drop" to the vaporization chamber 3, and a demineralizing cartridge 7 (see FIGS. 2, 3 and 4) placed in the water circuit which connects the reservoir 5 to the vaporization chamber 3.

L'ensemble des organes précités est coiffé par une carrosserie de protection 8.All of the aforementioned organs are capped by a protective bodywork 8.

Le réservoir d'eau 5 s'étend horizontalement entre l'avant et l'arrière du fer, au-dessus de la chambre de vaporisation 3. Celle-ci est séparée de la paroi supérieure de la chambre de vaporisation par une paroi 9 en matière plastique relativement épaisse qui isole thermiquement le réservoir d'eau 5 de la partie inférieure chaude du fer.The water tank 5 extends horizontally between the front and the rear of the iron, above the vaporization chamber 3. The latter is separated from the upper wall of the vaporization chamber by a wall 9 in relatively thick plastic which thermally insulates the water tank 5 from the hot lower part of the iron.

La partie avant du fer comporte un volet 10 qui dégage une ouverture 11 permettant d'introduire de l'eau (généralement de l'eau du robinet) dans le réservoir 5.The front part of the iron has a flap 10 which releases an opening 11 allowing water (generally tap water) to be introduced into the tank 5.

D'autres détails apparaissent sur la figure 1. Ceux-ci sont bien connus de l'homme du métier de sorte qu'il est inutile de les détailler ici.Other details appear in FIG. 1. These are well known to those skilled in the art, so that it is unnecessary to detail them here.

La cartouche déminéralisante 7 est disposée de façon amovible dans un logement 12 situé entre un réservoir primaire d'eau brute 5 et un réservoir secondaire d'eau déminéralisée 25, qui communique avec le dispositif d'alimentation d'eau 6. Cette cartouche 7 communique avec le réservoir primaire 5 et le réservoir secondaire 25 au moyen de clapets 27a, 27b évitant l'écoulement de l'eau, lorsque cette cartouche est retirée du fer.The demineralizing cartridge 7 is removably disposed in a housing 12 located between a primary tank of raw water 5 and a secondary tank of demineralized water 25, which communicates with the water supply device 6. This cartridge 7 communicates with the primary reservoir 5 and the secondary reservoir 25 by means of valves 27a, 27b preventing the flow of water, when this cartridge is removed from the iron.

Dans la réalisation représentée, le réservoir secondaire 25 est disposé à l'intérieur du réservoir primaire 5. De plus, le réservoir secondaire 25 est constitué de deux capacités 25c et 25d situées respectivement à la sortie de la cartouche 7 et autour du dispositif d'alimentation 6 de la chambre de vaporisation.In the embodiment shown, the secondary tank 25 is disposed inside the primary tank 5. In addition, the secondary tank 25 consists of two capacities 25c and 25d located respectively at the outlet of the cartridge 7 and around the device. supply 6 to the vaporization chamber.

Par ailleurs, le volume du réservoir secondaire 25 permet d'alimenter le dispositif d'alimentation 6 de la chambre de vaporisation losque celui-ci est ouvert à son débit maximum, durant au moins 30 secondes.Furthermore, the volume of the secondary reservoir 25 makes it possible to supply the supply device 6 of the vaporization chamber when the latter is open at its maximum flow rate, for at least 30 seconds.

Par ailleurs, chacun des réservoirs 5 et 25 possède des moyens de mise à l'air afin d'éviter qu'une ou des dépressions ne se créent lors de l'écoulement vers la chambre de vaporisation. L'un de ces moyens consiste en une tubulure 26a placée dans l'environnement proche du dispositif d'alimentation 6 de la chambre de vaporisation.Furthermore, each of the reservoirs 5 and 25 has means for venting in order to prevent one or more depressions from being created during the flow towards the vaporization chamber. One of these means consists of a tube 26a placed in the environment close to the supply device 6 of the vaporization chamber.

De façon plus précise, le réservoir secondaire 25 est constitué (voir figures 5 et 6) :

  • d'une capacité 25c contenant le clapet de retenue 27 à la sortie de la cartouche 7 ;
  • d'un conduit 25a situé sur ou sous le fond du réservoir 5, intégré à celui-ci par au moins une de ces parois (comme représenté), ou constitué d'un tube souple reliant les deux capacités 25c et 25d. Elle peut également être constituée par l'espace compris entre le fond du réservoir 5 et une seconde paroi (interne ou externe) couvrant tout ou partie du fond, afin d'augmenter le volume d'eau déminéralisée, sans modifier la perte de charge.
  • d'une capacité 25d entourant le dispositif d'alimentation 6 de la chambre de vaporisation.
More precisely, the secondary reservoir 25 is made up (see FIGS. 5 and 6):
  • with a capacity 25c containing the check valve 27 at the outlet of the cartridge 7;
  • a conduit 25a located on or under the bottom of the reservoir 5, integrated into the latter by at least one of these walls (as shown), or consisting of a flexible tube connecting the two capacities 25c and 25d. It can also be constituted by the space between the bottom of the reservoir 5 and a second wall (internal or external) covering all or part of the bottom, in order to increase the volume of demineralized water, without modifying the pressure drop.
  • with a capacity 25d surrounding the supply device 6 of the vaporization chamber.

Le clapet 27 de retenue du réservoir secondaire peut être supprimé afin de réduire la perte de charge vers la capacité 25, si l'on prévoit, sur la notice d'emploi, que l'utilisatrice devra laisser le fer à plat sur sa semelle. Cette position ne laisse échapper que peu d'eau, compte tenu de la forme et des niveaux des deux capacités constituant le réservoir secondaire 25.The secondary tank retaining valve 27 can be omitted in order to reduce the pressure drop towards capacity 25, if it is provided, on the instructions for use, that the user will have to leave the iron flat on her sole. This position leaves little water to escape, taking into account the shape and the levels of the two capacities constituting the secondary tank 25.

On voit d'autre part sur la figure 1 que la paroi arrière 8a de la carrosserie 8 est prolongée au-delà du bord arrière la de la semelle 1 et que le logement 12 de la cartouche déminéralisante 7 est situé dans ladite partie arrière ; ce logement 12 est ainsi situé à une distance suffisante de la semelle 1 pour éviter tout échauffement de la résine contenue dans la cartouche.We see on the other hand in Figure 1 that the rear wall 8a of the body 8 is extended beyond the rear edge of the sole 1 and that the housing 12 of the demineralizing cartridge 7 is located in said rear part; this housing 12 is thus located at a sufficient distance from the sole 1 to avoid overheating of the resin contained in the cartridge.

La cartouche déminéralisante 7 est disposée de façon amovible dans le logement 12 qui est lui-même intégré à la partie arrière du réservoir d'eau 5.The demineralizing cartridge 7 is removably placed in the housing 12 which is itself integrated into the rear part of the water tank 5.

On voit d'autre part sur la figure 1, que le fond 13 du logement 12 de la cartouche 7 est situé sensiblement au même niveau que le fond 5a du réservoir 5.On the other hand, it can be seen in FIG. 1 that the bottom 13 of the housing 12 of the cartridge 7 is situated substantially at the same level as the bottom 5a of the reservoir 5.

Par ailleurs, la paroi supérieure 14 du logement 12 de la cartouche 7 est adjacente à l'intérieur du réservoir d'eau 5.Furthermore, the upper wall 14 of the housing 12 of the cartridge 7 is adjacent to the interior of the water tank 5.

De plus, cette paroi supérieure 14 est inclinée vers l'avant du fer et est raccordée au fond 5a du réservoir d'eau par un pan incliné 15. Le bord arrière 15a ou sommet de ce pan incliné 15 est relié à la paroi supérieure 14 du logement 12 par une cloison transversale 16 formant avec cette paroi 14 un réceptacle 17 constituant une réserve d'eau.In addition, this upper wall 14 is inclined towards the front of the iron and is connected to the bottom 5a of the water tank by an inclined panel 15. The rear edge 15a or top of this inclined panel 15 is connected to the upper wall 14 of the housing 12 by a transverse partition 16 forming with this wall 14 a receptacle 17 constituting a water reserve.

On voit sur la figure 5 que le logement 12 de la cartouche 7 est moulé d'une seule pièce avec le fond 5a du réservoir 5.It can be seen in FIG. 5 that the housing 12 of the cartridge 7 is molded in one piece with the bottom 5a of the reservoir 5.

Par ailleurs, cette figure montre que le pan incliné 15 s'étend sur une partie seulement de la largeur du réservoir d'eau et son bord présente une bordure verticale 18.Furthermore, this figure shows that the inclined face 15 extends over only part of the width of the water tank and its edge has a vertical border 18.

Comme montré par les figures 1 à 3, le logement 12 de la cartouche 7 comporte sur sa face opposée à sa face d'entrée 19 qui débouche vers l'extérieur, une ouverture d'entrée 20a et une ouverture de sortie 20b raccordées de façon amovible à un embout d'entrée 21a et sortie d'eau 21b de la cartouche 7 (voir figure 4). Cette cartouche 7 présente une cloison médiane 22. A l'arrière des embouts 21a et 21b s'étend une grille de filtration 24 qui retient les particules de résine 23.As shown in Figures 1 to 3, the housing 12 of the cartridge 7 has on its face opposite to its inlet face 19 which opens outwards, an inlet opening 20a and an outlet opening 20b connected so removable to an inlet nozzle 21a and water outlet 21b of the cartridge 7 (see Figure 4). This cartridge 7 has a central partition 22. At the rear of the end pieces 21a and 21b extends a filtration grid 24 which retains the resin particles 23.

L'ouverture de sortie 20b du logement 12 est reliée au dispositif d'alimentation en eau 6 de la chambre de vaporisation 3 par le conduit 25 qui s'étend à l'intérieur du réservoir d'eau 5.The outlet opening 20b of the housing 12 is connected to the water supply device 6 of the vaporization chamber 3 through the conduit 25 which extends inside the water tank 5.

Par ailleurs, l'ouverture d'entrée 20a d'eau dans la cartouche 7 débouche dans un compartiment 26 qui est séparé de l'ouverture de sortie 20b par une cloison 27. Ce compartiment 26 est alimenté par l'eau contenue dans le réceptacle 17 formant réserve et est alimenté directement par l'eau du réservoir 5 proprement dit seulement lorsque le fer est en position verticale, comme on l'expliquera plus en détail plus loin.Furthermore, the water inlet opening 20a in the cartridge 7 opens into a compartment 26 which is separated from the outlet opening 20b by a partition 27. This compartment 26 is supplied with the water contained in the receptacle 17 forming a reserve and is supplied directly with water from the reservoir 5 proper only when the iron is in the vertical position, as will be explained in more detail below.

La figure 5 montre d'autre part qu'une partie 25a du conduit 25 est moulée d'une seule pièce avec le fond 5a du réservoir. L'autre partie qui vient coiffer la partie 25a du conduit est désignée par la référence 25b sur la figure 5. Cette partie 25a comporte également à son extrémité opposée à la sortie 20b du logement 12, un conduit vertical 26a de mise à l'air libre.Figure 5 shows on the other hand that a part 25a of the conduit 25 is molded in one piece with the bottom 5a of the tank. The other part which covers the part 25a of the duct is designated by the reference 25b in FIG. 5. This part 25a also comprises at its end opposite to the outlet 20b of the housing 12, a vertical duct 26a for venting free.

En haut de la figure 5, on a représenté la partie supérieure 5b du réservoir qui s'assemble sur sa partie 5a formant le fond du réservoir 5.At the top of FIG. 5, the upper part 5b of the tank is shown, which assembles on its part 5a forming the bottom of the tank 5.

Le réservoir comporte d'autre part, en regard des entrée 21a et sortie 21b de la cartouche 7 des clapets 27a, 27b sollicités chacun par un ressort 28 tendant à repousser la cartouche 7 vers l'extérieur. Ces clapets 27a, 27b sont maintenus ouverts par contact avec des butées 29 ménagés aux embouts 21a et 21b de la cartouche lorsque celle-ci est engagée dans le logement 17. Ces clapets 27a, 27b obturent les entrée 20a et sortie 20b du logement, par l'action des ressorts 28 qui poussent ces clapets sur des joints souples 30 engagés sur les embouts 21a, 21b lorsque la cartouche 7 est enlevée du logement 12.The reservoir further comprises, opposite the inlet 21a and outlet 21b of the cartridge 7, valves 27a, 27b each urged by a spring 28 tending to push the cartridge 7 outwards. These valves 27a, 27b are kept open by contact with stops 29 formed at the end pieces 21a and 21b of the cartridge when the latter is engaged in the housing 17. These valves 27a, 27b close the inlet 20a and outlet 20b of the housing, by the action of the springs 28 which push these valves onto flexible seals 30 engaged on the end pieces 21a, 21b when the cartridge 7 is removed from the housing 12.

Par ailleurs, comme montré par la figure 2, des moyens sont prévus pour verrouiller et déverrouiller la cartouche relativement au logement 12. Ces moyens coopèrent par encliquetage pour assurer le verrouillage et comprennent un organe accessible à l'utilisateur pour commander le déverrouillage.Furthermore, as shown in Figure 2, means are provided for locking and unlocking the cartridge relative to the housing 12. These means cooperate by snap-fastening to ensure locking and include a member accessible to the user for controlling the unlocking.

Sur la figure 2, on voit que la face inférieure de la cartouche 7 comporte un bec 31 qui est retenu dans un évidement 32 faisant partie d'une languette élastique 33 solidaire d'un poussoir 34 qui est monté coulissant sous le logement 12. La languette 33 présente en avant de l'évidement 32 une rampe 34 qui provoque le dégagement vers le bas de la languette 33 lorsqu'on appuie sur le poussoir 34. Ce mouvement libère le bec 31 de la cartouche 7 et celle-ci est alors poussée vers l'extérieur par les ressorts 28. Le dégagement de la cartouche 7 met automatiquement les clapets 27a et 27b en position d'obturation, c'est-à-dire en appui sur les joints souples 30.In FIG. 2, it can be seen that the underside of the cartridge 7 has a spout 31 which is retained in a recess 32 forming part of an elastic tongue 33 secured to a pusher 34 which is slidably mounted under the housing 12. The tongue 33 has in front of the recess 32 a ramp 34 which causes the tongue 33 to be released downward when the push-button 34 is pressed. This movement releases the spout 31 of the cartridge 7 and the latter is then pushed outwardly by the springs 28. The release of the cartridge 7 automatically puts the valves 27a and 27b in the closed position, that is to say resting on the flexible seals 30.

On va maintenant décrire en référence aux schémas des figures 6 et 7 le fonctionnement de l'alimentation en eau de la chambre de vaporisation à partir du réservoir d'eau 5.We will now describe with reference to the diagrams of FIGS. 6 and 7 the operation of the water supply to the vaporization chamber from the water tank 5.

Sur la figure 6, dans un but de clarté, les différentes parties du circuit d'alimentation en eau ont été mises bout à bout. Sur cette figure 6, le niveau N de l'eau contenue dans le réservoir 5 est inférieur au sommet S de la rampe 15 située entre le fond 5a du réservoir 5 et le réceptacle 17 qui communique avec la cartouche 7.In FIG. 6, for the sake of clarity, the different parts of the water supply circuit have been placed end to end. In this FIG. 6, the level N of the water contained in the tank 5 is lower than the top S of the ramp 15 situated between the bottom 5a of the tank 5 and the receptacle 17 which communicates with the cartridge 7.

Par conséquent, lorsque le fer est immobile, seule l'eau contenue dans le réceptacle 17 alimente le dispositif de réglage de débit 6 qui déverse l'eau goutte à goutte dans la chambre de vaporisation. L'eau traversant la cartouche 7 est débarrassée de tout élément tel que les ions calcium susceptibles d'entartrer la chambre de vaporisation.Consequently, when the iron is stationary, only the water contained in the receptacle 17 feeds the flow control device 6 which pours the water drop by drop into the vaporization chamber. The water passing through the cartridge 7 is freed from any element such as calcium ions liable to scale the vaporization chamber.

Lors du repassage, le déplacement du fer engendre dans l'eau contenue dans le réservoir 5 des vagues telles que l'eau peut remonter sur le pan incliné 15 et se déverser successivement dans le réceptacle 17 et maintenir dans celui-ci un niveau d'eau sensiblement constant.When ironing, the movement of the iron generates waves in the water contained in the tank 5 such that the water can rise on the inclined face 15 and pour successively into the receptacle 17 and maintain therein a substantially constant water level.

Etant donné que ce niveau est maintenu constant, le débit d'eau par le dispositif d'alimentation 6 est régulier.Since this level is kept constant, the water flow through the supply device 6 is regular.

Dans la position verticale de repos du fer, telle que représentée sur la figure 7, l'eau du réservoir 5 remplit également le réceptacle 17, la cartouche 7 et le conduit 26.In the vertical resting position of the iron, as shown in FIG. 7, the water from the reservoir 5 also fills the receptacle 17, the cartridge 7 and the conduit 26.

Ainsi, lorsque l'utilisateur ramène le fer en position horizontale pour repasser, le réceptacle 17 formant réserve d'eau se trouve rempli d'eau, de sorte que le fer est prêt à fonctionner.Thus, when the user returns the iron to a horizontal position for ironing, the receptacle 17 forming a reserve of water is filled with water, so that the iron is ready to operate.

Pour changer la cartouche 7, il suffit d'appuyer sur le poussoir 34 pour le déverrouiller de son logement 12. Lors de l'enlèvement de la cartouche 12 les clapets 27a, 27b sollicités par les ressorts ferment automatiquement les entrée et sortie d'eau, de sorte que l'eau du réservoir 5 ne peut s'écouler à l'extérieur.To change the cartridge 7, simply press the pusher 34 to unlock it from its housing 12. When removing the cartridge 12 the valves 27a, 27b urged by the springs automatically close the water inlet and outlet , so that the water in tank 5 cannot flow outside.

Il suffit ensuite d'engager une cartouche neuve dans le logement 12. L'enfoncement de celle-ci dans ce logement 12 provoque automatiquement l'ouverture des clapets 27a, 27b.It then suffices to engage a new cartridge in the housing 12. The insertion of the latter into this housing 12 automatically causes the valves 27a, 27b to open.

La paroi extérieure de la cartouche 7 est de préférence en matière plastique transparente pour pouvoir examiner le changement de couleur du produit situé à l'intérieur, qui permet à l'utilisateur d'apprécier s'il y a lieu de remplacer la cartouche.The outer wall of the cartridge 7 is preferably made of transparent plastic in order to be able to examine the change in color of the product located inside, which allows the user to assess whether it is necessary to replace the cartridge.

A titre d'exemple, le volume du réservoir primaire 5 est de 220 cm³. Celui du réservoir secondaire est de 7 cm³, ce qui permet, dans l'hypothèse où la cartouche est inopinément obturée, d'assurer 30 secondes de production de vapeur, le debit maximum de ce fer étant de 15g de vapeur par minute. Le volume du réservoir secondaire peut être augmenté (en particulier en augmentant la section du conduit 25) mais sans conséquence pratique, puisque le débit de vapeut n'est pas essentiellement tributaire du débit d'eau, mais de la puissance électrique de la semelle.For example, the volume of the primary reservoir 5 is 220 cm³. That of the secondary tank is 7 cm³, which allows, in the event that the cartridge is unexpectedly blocked, to ensure 30 seconds of steam production, the maximum flow rate of this iron being 15g of steam per minute. The volume of the secondary tank can be increased (in particular by increasing the section of the conduit 25) but without practical consequence, since the flow of vapor is not essentially dependent on the flow of water, but on the electrical power of the sole.

Pour que les réservoirs primaire et secondaire puissent se vider librement, ou, lorsque le fer est sur le talon, s'équilibrer librement, il faut que chacun d'eux soit en communication avec la pression atmosphérique (par la tubulure 26a et par le goulot d'entrée). Cette double mise à l'air est nécessaire par la présence de la résine échangeuse d'ions contenue dans la cartouche 7 qui présente une forte perte de charge. Cette masse, difficile à franchir par le courant d'eau, produirait une dépression dans le réservoir secondaire lors de son vidage dans la chambre de vaporisation, si la tubulure 26a n'existait pas, réduisant considérablement l'écoulement.So that the primary and secondary tanks can be emptied freely, or, when the iron is on the heel, to balance freely, each of them must be in communication with the atmospheric pressure (by the tubing 26a and by the neck entry). This double venting is necessary by the presence of the ion exchange resin contained in the cartridge 7 which has a high pressure drop. This mass, difficult to cross by the stream of water, would produce a vacuum in the secondary tank when it is emptied into the vaporization chamber, if the tubing 26a did not exist, considerably reducing the flow.

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.
