Description

FER A VAPEUR A RECHARGE D'EAU CHAUDE SOUS PRESSION STEAM IRON WITH PRESSURE HOT WATER UNDER PRESSURE
La présente invention concerne les fers à repasser électriques à vapeur permettant de repasser sans devoir être reliés par un cordon d'alimentation électrique.The present invention relates to electric steam irons for ironing without having to be connected by an electric power cord.
De tels fers à repasser, ci-après dits cordless, sont associés généralement à un socle qui lui est relié au secteur par un cordon d'alimentation, et sur lequel l'utilisateur vient déposer régulièrement le fer. Des moyens de connexion électrique sont prévus pour raccorder la partie arrière du fer au cordon d'alimentation électrique relié au socle, de façon que le fer, notamment sa semelle, puisse chauffer lorsqu'il est posé sur le socle. Ainsi, lorsque le fer est suffisamment chaud, l'utilisateur peut l'enlever du socle et procéder au repassage sans être gêné par le cordon d'alimentation.Such irons, hereinafter called cordless, are generally associated with a base which is connected to it by the mains by a power cord, and on which the user regularly deposits the iron. Electrical connection means are provided for connecting the rear part of the iron to the electrical supply cord connected to the base, so that the iron, in particular its soleplate, can heat up when it is placed on the base. Thus, when the iron is hot enough, the user can remove it from the base and proceed to ironing without being hindered by the power cord.
Pendant les temps de pause du repassage, la semelle emmagasine l'énergie nécessaire au repassage et à la vaporisation de l'eau. L'énergie nécessaire à la vaporisation pendant le temps de repassage est très supérieure à celle qui serait nécessaire à un simple repassage à sec. La puissance de chauffe et la capacité thermique de la semelle doivent être adaptées.During the ironing break times, the soleplate stores the energy necessary for ironing and spraying water. The energy required for vaporization during the ironing time is much higher than that which would be required for a simple dry ironing. The heating power and the thermal capacity of the soleplate must be adapted.
La capacité thermique de la semelle doit être suffisante pour que la température ne chute pas trop pendant le repassage. Mais satisfaire complètement à cette exigence conduit à des semelles épaisses et lourdes dont le coût est prohibitif. Des tentatives ont été faites pour utiliser la chaleur latente de fusion de corps complexes inclus dans la semelle, mais ces corps peuvent devenir dangereux en cas de fuite.The thermal capacity of the soleplate must be sufficient so that the temperature does not drop too much during ironing. But completely satisfying this requirement leads to thick and heavy soles, the cost of which is prohibitive. Attempts have been made to use the latent heat of fusion of complex bodies included in the sole, but these bodies can become dangerous if leaked.
La puissance du socle doit être élevée pour fournir pendant le seul temps de pause l'énergie nécessaire. Cependant on est limité par la puissance souscrite ou disponible de l'installation des usagers. Par ailleurs les fers ont un réservoir d'eau de vaporisation de capacité relativement faible, conduisant à des remplissages manuels fréquents, pendant lesquels il n'est pas recommandé de mettre le fer sous tension à cause des risques de débordement.The power of the base must be high to provide the necessary energy during the only pause time. However, we are limited by the subscribed or available power of the users' installation. In addition, the irons have a relatively low capacity vaporizing water tank, leading to frequent manual filling, during which it is not recommended to switch on the iron because of the risk of overflow.
Le brevet WO97/21866 décrit un fer cordless dans lequel le temps de recharge en énergie de chauffage est quelque peu diminué. Dans le socle, l'énergie est produite et accumulée dans un liquide chauffé qui est ensuite rapidement transféré dans le fer au niveau de la semelle pendant les temps de pause du repassage, ce liquide chauffé étant échangé avec le liquide refroidi de la séquence précédente. Mais ce dispositif de chauffage de semelle nécessite une très importante circulation de liquide chaud qui ne peut s'obtenir qu'avec une pompe spéciale ou par un délicat équilibrage de pression de plusieurs réservoirs, et deux raccords hydrauliques du fer au socle, ce qui augmente le risque de pannes. Par ailleurs le dispositif ne comporte pas d'alimentation du fer en eau de vaporisation ou en vapeur.WO97 / 21866 describes a cordless iron in which the heating energy recharge time is somewhat reduced. In the base, energy is produced and accumulated in a heated liquid which is then quickly transferred into the iron at the level of the soleplate during the ironing pause times, this heated liquid being exchanged with the cooled liquid of the previous sequence. But this sole heating device requires a very large circulation of hot liquid which can only be obtained with a special pump or by a delicate pressure balancing of several tanks, and two hydraulic connections from the iron to the base, which increases the risk of breakdowns. Furthermore, the device does not include supplying the iron with vaporizing water or steam.
Le brevet DE3538544 décrit l'accumulation d'énergie thermique dans le socle, cette énergie étant transférée au fer par conduction pendant les temps de pause du repassage. Mais ce dispositif nécessite un socle chaud qui peut être dangereux à l'usage.Patent DE3538544 describes the accumulation of thermal energy in the base, this energy being transferred to the iron by conduction during the ironing pause times. But this device requires a hot base which can be dangerous to use.
Le brevet US5315773 décrit un fer cordless dans lequel la recharge en eau de vaporisation s'effectue automatiquement quand le fer est sur son socle. Mais ce dispositif ne résout pas les problèmes de rapidité de transfert d'énergie du socle au fer à repasser.US Pat. No. 5,315,773 describes a cordless iron in which the recharging of vaporizing water takes place automatically when the iron is on its base. But this device does not solve the problems of speed of energy transfer from the base to the iron.
Par ailleurs on connaît les fers à repasser à vapeur dont le générateur de vapeur intégré est thermiquement indépendant de la semelle, mais ces appareils ne permettent pas le repassage sans cordon d'alimentation.Furthermore, steam irons are known, the integrated steam generator of which is thermally independent of the soleplate, but these devices do not allow ironing without a power cord.
L'invention ci-après a pour but un fer à repasser à vapeur cordless dont l'autonomie de la phase active de repassage est augmentée par rapport aux fers cordless classiques, avec une recharge automatique en eau de vaporisation pour ne pas nécessiter l'intervention de l'utilisateur. La conception d'un tel fer doit en outre être relativement simple pour assurer sa fiabilité.The aim of the invention below is to provide a cordless steam iron, the autonomy of the active ironing phase of which is increased compared to conventional cordless irons, with automatic recharging of steam water so as not to require intervention. of the user. The design of such an iron must also be relatively simple to ensure its reliability.
Le but de l'invention est atteint par un dispositif de repassage comportant un socle générateur d'eau chaude sous pression, des moyens de connexion rapide hydraulique et électrique d'un fer cordless au socle quand le fer est posé sur le socle, remarquable en ce que le fer cordless comporte une semelle et un générateur de vapeur interne thermiquement indépendants l'un de l'autre et respectivement munis de leurs propres moyens de chauffe et de régulation.The object of the invention is achieved by an ironing device comprising a base for generating hot water under pressure, means for rapid hydraulic and electrical connection of a cordless iron to the base when the iron is placed. on the base, remarkable in that the cordless iron comprises a soleplate and an internal steam generator thermally independent of each other and respectively provided with their own heating and regulation means.
Cette disposition permet le repassage à une température de semelle qui peut être ajustée à la demande, la vapeur n'étant pas produite par la chaleur emmagasinée par la semelle. D'une part la semelle emmagasine suffisamment d'énergie pour un repassage à sec sans cordon et ne se refroidit pas plus quand le fer vaporise car d'autre part le générateur interne au fer cordless se comporte indépendamment en tant qu'accumulateur, emmagasine et restitue une autre énergie suffisante pour produire la vaporisation de l'eau pendant le repassage.This arrangement allows ironing at a sole temperature which can be adjusted on demand, the steam not being produced by the heat stored by the sole. On the one hand the sole stores enough energy for a dry ironing without cord and does not cool more when the iron vaporizes because on the other hand the generator internal to the cordless iron behaves independently as an accumulator, stores and returns another energy sufficient to produce the vaporization of the water during ironing.
Par rapport à un fer cordless classique, toute l'énergie emmagasinée par la semelle est utilisée pour le repassage hors énergie de vaporisation, ce qui permet soit d'alléger la semelle pour qu'elle soit plus économique, soit pour un même coût d'avoir de préférence une autonomie sensiblement augmentée.Compared to a classic cordless iron, all the energy stored by the soleplate is used for ironing without vaporization energy, which makes it possible either to lighten the soleplate so that it is more economical, or at the same cost preferably have a significantly increased autonomy.
De préférence, le générateur interne du fer est un bouilleur composé d'un réservoir résistant à la pression relié aux moyens hydrauliques de connexion rapide du fer avec le socle, équipé d'un élément chauffant électrique et d'une vanne de sortie de vapeur. De préférence, le fer étant sur son socle, le générateur de vapeur interne est rempli d'eau chaude pressurisée préalablement produite et stockée dans le générateur du socle.Preferably, the internal generator of the iron is a boiler consisting of a pressure-resistant tank connected to the hydraulic means for rapid connection of the iron with the base, equipped with an electric heating element and a steam outlet valve. Preferably, the iron being on its base, the internal steam generator is filled with pressurized hot water previously produced and stored in the base generator.
Le remplissage du bouilleur se fait par équilibrage des pressions entre le générateur du socle et celui du fer. Le fer étant froid ou ayant perdu de la chaleur pendant le repassage, la pression du bouilleur du fer est faible tandis que celle du générateur du socle est maintenue élevée en permanence. L'eau contenue dans le socle s'écoule rapidement du socle vers le bouilleur du fer à travers les moyens de connexion hydrauliques et remplit le bouilleur complètement sauf au premier cycle où il reste un peu d'air. Cet air est entraîné par la vapeur aux prochains cycles de repassage.The filling of the boiler is done by balancing the pressures between the base generator and that of the iron. The iron being cold or having lost heat during ironing, the pressure of the iron boiler is low while that of the base generator is kept permanently high. The water contained in the base quickly flows from the base to the boiler of the iron through the hydraulic connection means and fills the boiler completely except in the first cycle where a little air remains. This air is entrained by steam during the next ironing cycles.
L'eau de remplissage se mélange avec l'eau résiduelle du bouilleur en apportant rapidement une grande quantité de chaleur et en la réchauffant. En faisant chuter la pression on pourrait provoquer l'évaporation d'une partie de cette eau et obtenir de la vapeur.The filling water mixes with the residual water from the boiler quickly bringing in a large amount of heat and warming it up. By lowering the pressure we could cause some of this water to evaporate and get steam.
De préférence, pendant que le fer est sur son socle, le chauffage du générateur de vapeur interne au fer est en marche et réchauffe l'eau, produisant de la vapeur, augmentant la pression au delà de celle du générateur du socle, cette pression refoulant dans le socle une partie de l'eau du bouilleur jusqu'à l'embouchure d'un conduit d'admission d'eau dans le bouilleur.Preferably, while the iron is on its base, the heating of the steam generator internal to the iron is on and heats the water, producing steam, increasing the pressure beyond that of the base generator, this pressure releasing in the base part of the water from the boiler to the mouth of a water inlet pipe into the boiler.
Grâce à cette caractéristique, on assure que le mélange résultant est à une température convenable pour assurer une évaporation de l'eau en quantité suffisante pendant tout le repassage actif. En outre on assure que la vanne de sortie de vapeur est hors d'eau, pour permettre l'évacuation de la vapeur.Thanks to this characteristic, it is ensured that the resulting mixture is at a suitable temperature to ensure sufficient evaporation of the water during all the active ironing. In addition, it is ensured that the steam outlet valve is out of water, to allow the evacuation of the steam.
La vanne de sortie de vapeur se trouve alors toujours dégagée. Un volume de vapeur est disponible et, le fer étant sorti du socle en position de repassage, on peut agir sur la vanne de sortie pour obtenir de la vapeur. La pression de l'eau et celle de la vapeur s'équilibrent, faisant que l'eau se met à bouillir, même n'étant pas chauffée, et se refroidit lentement.The steam outlet valve is then always free. A volume of steam is available and, the iron having left the base in the ironing position, one can act on the outlet valve to obtain steam. The pressure of the water and that of the steam equilibrate, causing the water to boil, even when not heated, and cool slowly.
Dans cette opération l'essentiel de l'énergie de vaporisation a donc été fourni au moment du remplissage rapide du bouilleur pendant le temps de pause du repassage, avec un complément d'énergie fourni par l'élément chauffant du bouilleur interne au fer cordless. Dans le même temps la semelle nécessitant bien moins d'énergie a été réchauffée indépendamment.In this operation, most of the vaporization energy was therefore supplied at the time of rapid filling of the boiler during the ironing pause time, with additional energy supplied by the heating element of the internal boiler to the cordless iron. At the same time the sole requiring much less energy has been heated independently.
De plus, à chaque cycle de remplissage, pendant la pause, le niveau d'eau est ajusté toujours à la hauteur de l'embouchure du conduit d'admission de l'eau chaude dans le bouilleur de sorte que le niveau de remplissage du fer en eau de vaporisation est maintenu automatiquement et ne nécessite aucune intervention de l'utilisateur.In addition, during each filling cycle, during the pause, the water level is always adjusted to the height of the mouth of the hot water inlet duct to the boiler so that the filling level of the iron water vaporization is maintained automatically and requires no user intervention.
Avantageusement, les moyens de connexion rapide appartenant au fer sont situés sur le talon du fer et le niveau d'admission de l'eau chaude dans le bouilleur sur son socle est défini par l'extrémité d'une canule dont l'autre extrémité est reliée aux moyens de connexion hydraulique. Utilement, la canule est interne au bouilleur.Advantageously, the quick connection means belonging to the iron are located on the heel of the iron and the level of admission of hot water into the boiler on its base is defined by the end of a cannula, the other end of which is connected to the hydraulic connection means. Usefully, the cannula is internal to the boiler.
Cette disposition constructive permet un réglage facile du niveau de remplissage et un gain de place en logeant facilement la tuyauterie constituée par la canule. Utilement l'élément chauffant du générateur interne au fer chauffe le bouilleur sur une paroi ou une partie de paroi qui se trouve en dessous de l'embouchure du conduit d'admission d'eau lorsque le fer est sur son socle.This constructive arrangement allows easy adjustment of the filling level and saves space by easily accommodating the piping formed by the cannula. Usefully, the heating element of the internal iron generator heats the boiler on a wall or part of a wall which is located below the mouth of the water intake duct when the iron is on its base.
La paroi chauffée est ainsi constamment en contact avec l'eau et aucune surchauffe de l'élément chauffant ne peut survenir. Avantageusement, la vanne de sortie de vapeur est aussi une vanne s'ouvrant en cas de surpression anormale dans le bouilleur.The heated wall is thus constantly in contact with water and no overheating of the heating element can occur. Advantageously, the steam outlet valve is also a valve opening in the event of abnormal overpressure in the boiler.
Si le refoulement de l'eau dans le bouilleur ne pouvait avoir lieu on dispose ainsi d'une sécurité.If the backflow of water into the boiler could not take place, this provides security.
De préférence, le générateur d'eau chaude contenu dans le socle comporte une cuve de chauffage contenant de la vapeur saturée surmontant l'eau chaude maintenue à niveau sensiblement constant.Preferably, the hot water generator contained in the base comprises a heating tank containing saturated steam overcoming the hot water maintained at substantially constant level.
Le volume de vapeur est d'une part compressible et d'autre part condensable sous une pression supérieure à la pression de vapeur saturante. La présence de ce volume de vapeur permet le refoulement de l'eau du fer vers cette cuve, le volume refoulé étant inférieur au volume de vapeur contenu dans la cuve.The volume of vapor is on the one hand compressible and on the other hand condensable under a pressure greater than the saturated vapor pressure. The presence of this volume of steam allows the water to flow back from the iron to this tank, the volume delivered being less than the volume of steam contained in the tank.
Dans une version préférentielle le générateur d'eau chaude du socle comprend un réservoir d'eau à pression ambiante et une pompe de remplissage de la cuve à partir de ce réservoir.In a preferred version the hot water generator of the base comprises a water tank at ambient pressure and a pump for filling the tank from this tank.
Le remplissage en eau du système de repassage peut se faire à tout moment. L'invention sera mieux comprise au vu de l'exemple décrit ci après et des dessins annexés.The ironing system can be filled with water at any time. The invention will be better understood on the basis of the example described below and the attached drawings.
La figure 1 est une section schématique par un plan vertical longitudinal d'un dispositif de repassage selon l'invention, le fer étant sur son socle.Figure 1 is a schematic section through a longitudinal vertical plane of an ironing device according to the invention, the iron being on its base.
La figure 2 est une section schématique par un plan vertical longitudinal d'un fer selon l'invention dans une position de repassage sur un plan horizontal.Figure 2 is a schematic section through a longitudinal vertical plane of an iron according to the invention in an ironing position on a plane horizontal.
Dans une version préférentielle représentée en figure 1 le dispositif de repassage comporte un fer 1 et un socle 2.In a preferred version shown in FIG. 1, the ironing device comprises an iron 1 and a base 2.
Le socle 2 relié au secteur électrique par des moyens non représentés contient un générateur d'eau chaude sous une pression relative de l'ordre de 2,5 bars et une partie des moyens de raccordement hydraulique 3 et électrique prévus pour alimenter le fer 1 en eau chaude et en électricité. Le générateur comprend un réservoir d'eau à température ambiante 201 avec un orifice de remplissage 202, une pompe électrique 203 de préférence électromagnétique vibrante susceptible de compléter le niveau d'eau 205 dans une cuve 204 de chauffage de l'eau, à partir du réservoir d'eau 201. La pompe 203 comporte un clapet anti retour de l'eau. La cuve 204 est chauffée par un élément chauffant électrique 206 noyé dans une plaque 207. Des capteurs 208 permettent la régulation du niveau 205 et de la température de l'eau dans la cuve 204. Une conduite 209 relie la base de la cuve 204 aux moyens de raccordement 3 afin de permettre les prélèvements d'eau chaude. La régulation de la cuve 204 est telle qu'il reste en permanence un volume de vapeur saturante 210 au dessus du niveau d'eau 205.The base 2 connected to the electrical sector by means not shown contains a generator of hot water under a relative pressure of the order of 2.5 bars and part of the hydraulic 3 and electrical connection means provided for supplying the iron 1 with hot water and electricity. The generator comprises a room temperature water tank 201 with a filling orifice 202, an electric pump 203 preferably electromagnetic vibrating capable of supplementing the water level 205 in a tank 204 for heating the water, from the water tank 201. The pump 203 includes a non-return valve for water. The tank 204 is heated by an electric heating element 206 embedded in a plate 207. Sensors 208 allow the regulation of the level 205 and the temperature of the water in the tank 204. A pipe 209 connects the base of the tank 204 to the connection means 3 to allow the withdrawal of hot water. The regulation of the tank 204 is such that a volume of saturated vapor 210 remains permanently above the water level 205.
Le fer 1 est posé sur une face 211 du socle dans une position angulaire qui se rapproche de la verticale. Ce fer est connecté par le talon au socle via les moyens de raccordement hydraulique 3 et électrique. La position inclinée du fer facilite la connexion au socle. La structure du fer est mieux détaillée en figure 2 où il est représenté en position de repassage horizontal.The iron 1 is placed on one face 211 of the base in an angular position which approaches the vertical. This iron is connected by the heel to the base via the hydraulic and electrical connection means 3. The inclined position of the iron facilitates connection to the base. The structure of the iron is better detailed in Figure 2 where it is shown in the horizontal ironing position.
La semelle 101 du fer 1 est en liaison thermique avec un corps chauffant 102, constituant une masse d'accumulation thermique, muni d'un élément chauffant électrique 103. La régulation propre à la semelle n'est pas représentée. Des trous 104 permettent le passage de la vapeur sur le linge. Une chambre et/ou des canaux de distribution 105 permettent de répartir la vapeur vers les trous 104. Le fer 1 comporte un générateur de vapeur interne qui est un bouilleur constitué par un réservoir 110, d'environ 220 centimètres cube dans cet exemple, équipé d'un élément chauffant 111 permettant le chauffage et la vaporisation de l'eau quand le fer est sur son socle. La température du bouilleur est régulée par un thermostat 112. Une vanne 113 permet la vaporisation sur le linge en libérant sur commande la vapeur du bouilleur 110 vers la chambre 105. Un bouton 114 muni d'un ressort de rappel 115 permet la commande de la vanne 113. Avantageusement le ressort de rappel 115 est taré pour laisser la vanne 113 s'ouvrir en cas de surpression dans le bouilleur 110. Le bouilleur 110 comporte une embouchure de remplissage 117 constituée par l'extrémité d'une canule 116 reliée à son autre extrémité à la partie 31 propre au fer des moyens de raccordement hydraulique 3. De façon connue les moyens de raccordement hydraulique 3 établissent la continuité du circuit entre la canule 116 et la conduite 209 quand le fer est sur son socle et ferment les extrémités correspondantes quand le fer est enlevé de son socle. Dans la partie 31 des moyens 3 un clapet 32 est rappelé contre son siège par un ressort et par la pression du bouilleur 110 lorsque la connexion n'est pas réalisée, alors que ce même clapet 32 est ouvert mécaniquement dans l'autre cas. Un dispositif similaire se trouve sur la partie des moyens 3 appartenant au socle.The sole 101 of the iron 1 is in thermal connection with a heating body 102, constituting a mass of thermal accumulation, provided with an electric heating element 103. The regulation specific to the sole is not shown. Holes 104 allow the passage of steam over the laundry. A chamber and / or distribution channels 105 make it possible to distribute the steam towards the holes 104. The iron 1 comprises an internal steam generator which is a boiler constituted by a tank 110, of approximately 220 cubic centimeters in this example, equipped a heating element 111 allowing the heating and the vaporization of water when the iron is on its base. The temperature of the boiler is regulated by a thermostat 112. A valve 113 allows the vaporization on the linen by releasing on command the steam from the boiler 110 towards the chamber 105. A button 114 provided with a return spring 115 allows the control of the valve 113. Advantageously the return spring 115 is calibrated to let the valve 113 open in the event of overpressure in the boiler 110. The boiler 110 has a filling mouth 117 formed by the end of a cannula 116 connected to its other end to the part 31 specific to the iron of the hydraulic connection means 3. In known manner the hydraulic connection means 3 establish the continuity of the circuit between the cannula 116 and the line 209 when the iron is on its base and close the corresponding ends when the iron is removed from its base. In the part 31 of the means 3, a valve 32 is urged against its seat by a spring and by the pressure of the boiler 110 when the connection is not made, while this same valve 32 is opened mechanically in the other case. A similar device is located on the part of the means 3 belonging to the base.
Pour utiliser le dispositif, l'utilisateur remplit d'eau le réservoir 201 par l'orifice 202, pose le fer 1 sur le socle contre la face 211 et effectue de ce fait la connexion par le talon du fer sur le socle. Elle branche le socle au secteur électrique. La pompe établit le niveau 205 dans la cuve 204 et les éléments chauffants 207, 103, 111 sont en chauffe sous contrôle des différentes régulations. La semelle 101 et la masse thermique 102 s'échauffent à la température de consigne réglée par l'utilisateur. La pression augmentant dans la cuve 204 jusqu'à environ 2,5 bars, l'eau s'écoule via les moyens 3 dans le bouilleur 110 qu'elle remplit presque complètement à l'exception d'un volume d'air résiduel 118 maintenant un niveau haut 119. L'élément chauffant 111 fait alors monter la pression dans le bouilleur du fer 1 un peu au delà de la pression de la cuve 204. Cette surpression refoule l'eau via les moyens 3 dans la cuve 204. Quand le niveau d'eau dans le bouilleur 110 atteint l'embouchure de remplissage 117 à l'extrémité de la canule 116, la surpression de vapeur produite dans le bouilleur 110 s'échappe et arrête de refouler l'eau. La position de l'embouchure 117 est telle qu'il reste une quantité importante d'eau dans le réservoir 110 tout en dégageant la vanne 113 dans un espace suffisant pour qu'elle n'entraîne pas de gouttes d'eau pouvant engendrer des crachements du fer. A cette dernière fin des déflecteurs 120 situés dans l'environnement de la vanne 113 peuvent avantageusement compléter le dispositif. Dans cet exemple il reste alors environ 150 grammes d'eau dans le bouilleur 110. Elle a accumulé un maximum d'énergie, de la vapeur libre est disponible, la vanne 113 est hors d'eau, le fer est alors prêt à être utilisé dans les meilleures conditions. L'eau refoulée retourne dans le bouilleur 204 en le comprimant, ce qui provoque la condensation d'une partie du volume de vapeur saturante 210 situé au dessus du niveau 205 et laisse de la place à l'eau refoulée.To use the device, the user fills the reservoir 201 with water through the orifice 202, places the iron 1 on the base against the face 211 and therefore makes the connection by the heel of the iron on the base. It connects the base to the electrical sector. The pump establishes the level 205 in the tank 204 and the heating elements 207, 103, 111 are heating under control of the various regulations. The sole 101 and the thermal mass 102 heat up to the set temperature set by the user. The pressure increasing in the tank 204 up to approximately 2.5 bars, the water flows via the means 3 into the boiler 110 which it fills almost completely except for a volume of residual air 118 now a high level 119. The heating element 111 then increases the pressure in the boiler of the iron 1 a little beyond the pressure of the tank 204. This overpressure discharges the water via the means 3 into the tank 204. When the water level in the boiler 110 reaches the filling mouth 117 at the end of the cannula 116, the overpressure of vapor produced in the boiler 110 escapes and stops pumping the water. The position of the mouthpiece 117 is such that a large amount of water remains in the tank 110 while releasing the valve 113 in a space sufficient for it to not cause drops of water which can cause spitting. iron. For this latter end, the deflectors 120 situated in the environment of the valve 113 can advantageously complete the device. In this example there is then approximately 150 grams of water in the boiler 110. It has accumulated a maximum of energy, free steam is available, the valve 113 is out of water, the iron is then ready to be used in the best conditions. The pumped water returns to the boiler 204 by compressing it, which causes the condensation of part of the volume of saturated vapor 210 located above the level 205 and leaves room for the pumped water.
L'utilisateur se saisit du fer 1 et peut repasser. La semelle 101 et la masse 102 étant chaudes, elle peut repasser à sec, ce qui consomme relativement peu d'énergie fournie par la chaleur sensible de la semelle 101 et de la masse 102. Quand elle appuie sur le bouton 114 la vapeur contenue dans le bouilleur 110 s'échappe avec l'air résiduel vers les trous de vapeur 104. La pression chute dans le bouilleur, et l'eau bout de façon à rétablir l'équilibre de pression liquide vapeur, bien que l'élément chauffant 111 soit déconnecté de toute source d'électricité. La vapeur est donc produite grâce à l'enthalpie de l'eau du réservoir 110 sans consommer la chaleur de la semelle. La température et la pression baissent lentement dans le bouilleur avec la quantité de vapeur produite jusqu'à ce que l'utilisateur pose à nouveau le fer sur son socle. A titre d'exemple d'un cas typique d'utilisation, l'utilisateur aura vaporisé son linge pendant 20 secondes à un débit moyen de l'ordre de 50 g/min tandis que la pression dans le bouilleur aura chuté de 2,6 à 1bar.The user picks up iron 1 and can iron. The sole 101 and the mass 102 being hot, it can iron dry, which consumes relatively little energy supplied by the sensible heat of the sole 101 and the mass 102. When it presses the button 114 the vapor contained in the boiler 110 escapes with the residual air towards the steam holes 104. The pressure drops in the boiler, and the water boils so as to restore the liquid vapor pressure balance, although the heating element 111 is disconnected from any source of electricity. The vapor is therefore produced by the enthalpy of the water in the reservoir 110 without consuming the heat of the sole. The temperature and pressure drop slowly in the boiler with the amount of steam produced until the user puts the iron back on its base. As an example of a typical use case, the user will have sprayed his laundry for 20 seconds at an average flow rate of around 50 g / min while the pressure in the boiler will have dropped by 2.6 at 1bar.
A ce moment le fer étant refroidi la pression est relativement faible dans le bouilleur qui se remplit complètement puisque l'air résiduel s'est échappé, l'eau chaude se mélange à l'eau résiduelle en la réchauffant, puis un nouveau refoulement se produit grâce au réchauffement additionnel par l'élément chauffant 111. De nombreux essais ont montré que le temps de réchauffage complémentaire n'excède pas 15 secondes. Les niveaux d'eau et de température sont rétablis et de nouveaux cycles de repassage peuvent alors reprendre. At this time the iron being cooled the pressure is relatively low in the boiler which fills completely since the residual air has escaped, the hot water mixes with the residual water by heating it, then a new delivery occurs thanks to the additional heating by the heating element 111. Numerous tests have shown that the additional heating time does not exceed 15 seconds. Water and temperature are restored and new ironing cycles can resume.
