Description

La présente invention se rapporte à un appareil de repassage comportant un fer à repasser sans fil et une base de recharge sur laquelle le fer à repasser sans fil est disposé lors des phases inactives de repassage pour permettre un échange d'énergie entre la base de recharge et le fer à repasser, et se rapporte plus particulièrement à un appareil de repassage comportant un fer à repasser comprenant un réservoir d'eau, un corps chauffant muni d'une chambre de vaporisation pour la production de vapeur et un circuit pour la distribution de vapeur vers le linge à repasser.The present invention relates to an ironing apparatus comprising a cordless iron and a charging base on which the cordless iron is arranged during the inactive ironing phases to allow an exchange of energy between the charging base and the iron, and relates more particularly to an ironing apparatus comprising an iron comprising a water tank, a heating body provided with a vaporization chamber for the production of steam and a circuit for the distribution of steam. steam to the clothes to iron.

Il est connu, de la demande de brevet GB 2 179 961 , un appareil de repassage comportant un fer à repasser sans fil et une base de recharge comprenant un socle sur lequel le fer à repasser sans fil peut être disposé pour permettre le chauffage de la semelle par un échange d'énergie entre la base de recharge reliée au réseau électrique et le fer sans fil. Dans ce document, le fer à repasser permet le repassage à la vapeur, cependant il est nécessaire d'utiliser le fer à repasser dans un mode connecté, avec le fer relié à un réseau électrique par un cordon, lorsque l'utilisateur souhaite repasser avec un débit de vapeur relativement important.It is known from the patent application GB 2 179 961 , an ironing apparatus comprising a cordless iron and a charging base comprising a base on which the cordless iron can be arranged to allow heating of the soleplate by an exchange of energy between the connected charging base to the electrical network and the wireless iron. In this document, the iron is steam ironing, however it is necessary to use the iron in a connected mode, with the iron connected to an electrical network by a cord, when the user wishes to iron with a relatively large steam flow.

Une telle solution n'est pas satisfaisante pour l'utilisateur qui souhaite repasser avec un bon débit de vapeur étant donné que le fer à repasser ne présente plus alors les avantages d'un fer à repasser sans fil.Such a solution is not satisfactory for the user who wishes to iron with a good flow of steam since the iron then no longer has the advantages of a cordless iron.

Il est également connu, de la demande de brevet WO 02 101 138 , un appareil de repassage comportant un fer à repasser sans fil et une base de recharge dans lequel le fer à repasser peut fonctionner avec un plus grand débit de vapeur lorsqu'il est utilisé en mode connecté que lorsqu'il est utilisé en mode sans fil. Toutefois, cet appareil ne permet pas d'avoir des performances de repassage satisfaisante le débit de vapeur et l'autonomie en mode sans fil étant trop limitée.It is also known from the patent application WO 02 101 138 , an ironing machine with a cordless iron and a charging base in which the iron can operate with a greater flow of steam when used in connected mode than when it is used in wireless mode . However, this device does not allow to have satisfactory ironing performance steam flow and autonomy in wireless mode is too limited.

Aussi, un but de la présente invention est de proposer un appareil de repassage équipé d'un fer à repasser sans fil muni d'une chambre de vaporisation pour la production de vapeur qui procure une excellente qualité de repassage, grâce notamment à l'obtention d'un bon débit de vapeur et à une bonne autonomie lors des phases actives de repassage.It is therefore an object of the present invention to provide a ironing equipped with a cordless iron with a vaporization chamber for the production of steam which provides an excellent ironing quality, thanks in particular to obtaining a good flow of steam and a good autonomy during the active ironing phases.

A cet effet, l'invention a pour objet un appareil de repassage comportant un fer à repasser sans fil et une base de recharge sur laquelle le fer à repasser est disposé lors des phases inactives de repassage pour permettre un échange d'énergie entre la base de recharge et le fer à repasser, le fer à repasser comportant un réservoir d'eau et un corps chauffant muni d'une chambre de vaporisation pour la production de vapeur, le réservoir communiquant avec la chambre de vaporisation au moyen d'un circuit d'alimentation, caractérisé en ce que le circuit d'alimentation comporte des moyens obturateurs mobiles entre une position fermée, dans laquelle les moyens obturateurs interrompent la circulation d'eau au travers du circuit d'alimentation, et une position ouverte dans laquelle les moyens obturateurs laissent passer l'eau au travers du circuit d'alimentation, et en ce que les moyens obturateurs sont amenés en position ouverte en actionnant un bouton de commande de la vapeur porté par le fer à repasser et sont ramenés automatiquement en position fermée par des moyens de rappel lorsque l'utilisateur relâche le bouton de commande de la vapeur.For this purpose, the subject of the invention is an ironing apparatus comprising a cordless iron and a charging base on which the iron is placed during the inactive ironing phases to allow an exchange. between the charging base and the iron, the iron comprising a water tank and a heating body provided with a vaporization chamber for the production of steam, the tank communicating with the vaporization chamber at means of a supply circuit, characterized in that the supply circuit comprises shutter means movable between a closed position, wherein the shutter means interrupt the flow of water through the supply circuit, and a position open in which the shutter means pass water through the supply circuit, and in that the shutter means are brought into the open position by actuating a control button of the steam carried by the iron and are returned automatically in the closed position by return means when the user releases the steam control button.

Une telle caractéristique a pour effet d'augmenter l'autonomie du fer lors des phases actives de repassage, c'est-à-dire à augmenter la capacité du fer à conserver une température de fonctionnement suffisante pour l'obtention d'une bonne qualité de repassage. En effet, la présence du bouton de commande de la vapeur permet d'éviter une production de vapeur inutile lors de la phase de mise en place du fer sur la base de recharge ainsi que lors des phases de manipulation rapide du linge alors que le fer à repasser reste immobile à plat sur la table. On constate en moyenne, grâce à la présence du bouton de commande de la vapeur, une économie d'énergie de l'ordre de 15% par rapport à un fer à repasser sans fil produisant de la vapeur en continu.Such a characteristic has the effect of increasing the autonomy of the iron during the active ironing phases, that is to say to increase the capacity of the iron to maintain a sufficient operating temperature to obtain a good quality ironing. In fact, the presence of the steam control button makes it possible to avoid unnecessary steam production during the setting up phase of the iron on the charging base as well as during the rapid handling phases of the laundry while the iron to iron remains still on the table. On average, thanks to the presence of the steam control button, an energy saving of about 15% is observed compared to a cordless iron producing continuous steam.

Selon une autre caractéristique de l'invention, les moyens obturateurs sont constitués par un clapet obturateur ramené par un ressort de rappel dans la position de repos dans laquelle le clapet obturateur interrompt l'alimentation en eau de la chambre de vaporisation, l'actionnement dudit bouton de commande de la vapeur provoquant le déplacement dudit clapet obturateur vers la position ouverte dans laquelle l'eau en provenance du réservoir peut s'écouler vers la chambre de vaporisation.According to another characteristic of the invention, the shutter means are constituted by a shutter valve brought back by a return spring in the rest position in which the shutter valve interrupts the supply of water to the vaporization chamber, the actuation of said steam control button causing said shutter valve to move to the open position in which water from the reservoir can flow to the vaporization chamber.

De manière préférentielle, le circuit d'alimentation comporte également une vanne anti-goutte 7, visible sur la figure 8, disposée dans le fond du réservoir 13 au départ du circuit d'alimentation, la vanne anti-goutte 7 étant ramenée par un ressort de rappel 70 dans une position fermée, illustrée sur la figure 8, dans laquelle l'extrémité supérieure de la vanne anti-goutte 7 ferme un orifice de passage 13A et empêche l'écoulement de l'eau du réservoir 13 vers une première portion 13B du circuit d'alimentation s'étendant entre le réservoir 13 et le clapet obturateur 6.Preferably, the supply circuit also comprises an anti-drip valve 7, visible on the figure 8 disposed in the bottom of the tank 13 at the start of the supply circuit, the anti-drip valve 7 being returned by a return spring 70 in a closed position, illustrated in FIG. figure 8 , wherein the upper end of the drip valve 7 closes a through hole 13A and prevents the flow of water from the tank 13 to a first portion 13B of the supply circuit extending between the tank 13 and the shutter valve 6.

Conformément à la figure 9, la vanne anti-goutte 7 peut être déplacée vers une position ouverte par un pion 71 disposé sous la vanne anti-goutte 7, le pion 71 étant monté coulissant au travers d'un écran thermique 17 séparant le corps chauffant 3 du réservoir 13 et étant lui-même déplacé par un élément thermiquement déformable constitué par un bilame 72 porté par le corps chauffant 3, le bilame 72 étant dimensionné pour se déformer et assurer l'ouverture de la vanne anti-goutte 7 lorsque la température de la chambre de vaporisation 32 est suffisante pour produire de la vapeur, c'est-à-dire est supérieure à 100°C.In accordance with the figure 9 , the anti-drip valve 7 can be moved to an open position by a pin 71 placed under the anti-drip valve 7, the pin 71 being slidably mounted through a heat shield 17 separating the heating body 3 from the tank 13 and being itself displaced by a thermally deformable element constituted by a bimetallic strip 72 carried by the heating body 3, the bimetallic strip 72 being dimensioned to deform and to ensure the opening of the anti-drip valve 7 when the temperature of the vaporization chamber 32 is sufficient to produce steam, that is to say is greater than 100 ° C.

De manière préférentielle, la première portion 13B du circuit d'alimentation comporte une bifurcation 13C dans laquelle vient puiser une première pompe 8 manuelle permettant la génération d'un surplus de vapeur, la première portion 13B du circuit d'alimentation étant mise à l'air par un évent afin de faciliter le pompage, l'évent étant avantageusement constitué par les différents jeux existants au niveau des organes assurant le guidage en translation de la tige d'actionnement 62 dans le boîtier 10.Preferably, the first portion 13B of the feed circuit comprises a bifurcation 13C in which is drawn a first manual pump 8 for generating a surplus of steam, the first portion 13B of the feed circuit being set to air through a vent to facilitate pumping, the vent being advantageously constituted by the different existing games at the level of the members ensuring the translational guidance of the actuating rod 62 in the housing 10.

La première pompe 8 peut être actionnée au moyen d'un premier bouton 80 disposé sur la partie supérieure avant de la poignée de préhension 11 et permet d'envoyer de l'eau dans une canalisation 81, visible en partie sur les figures 5 et 6, qui débouche dans une chambre de vaporisation secondaire 33 intégrée dans le corps chauffant 3 à proximité immédiate de la résistance électrique 31, la chambre de vaporisation secondaire 33 communiquant, de manière connue en soi, avec un nombre restreint de trous 20 de sortie de vapeur disposés à l'avant de la semelle.The first pump 8 can be actuated by means of a first button 80 disposed on the upper front portion of the handle 11 and allows water to be sent into a pipe 81, visible in part on the figures 5 and 6 , which opens into a secondary vaporization chamber 33 integrated in the heating body 3 in the immediate vicinity of the electrical resistance 31, the secondary vaporization chamber 33 communicating, in a manner known per se, with a small number of steam outlet holes 20 arranged at the front of the sole.

Le fer à repasser comporte également une deuxième pompe manuelle 9 comportant un conduit d'admission 91, visible sur la figure 9, débouchant directement dans le réservoir 13, cette deuxième pompe 9 pouvant être actionnée au moyen d'un second bouton 90 disposé à côté du premier bouton 80 et étant reliée par une canalisation, non visible sur les figures, à une buse de pulvérisation 92, visible sur les figures 5 et 6, disposée sur la face avant du fer à repasser 1.The iron also comprises a second manual pump 9 comprising an intake duct 91, visible on the figure 9 , opening directly into the reservoir 13, this second pump 9 being actuatable by means of a second button 90 disposed next to the first button 80 and being connected by a pipe, not visible in the figures, to a spray nozzle 92, visible on figures 5 and 6 , arranged on the front face of the iron 1.

Le fonctionnement de l'appareil de repassage ainsi réalisé va maintenant être décrit.The operation of the ironing apparatus thus produced will now be described.

Lorsque l'utilisateur souhaite effectuer une séance de repassage, il remplit le réservoir 13 d'eau et branche le cordon d'alimentation 101 de la base de recharge 100 sur le réseau électrique domestique en laissant le fer à repasser 1 connecté à la base de recharge 100. La résistance 31 du corps chauffant 3 est alors alimentée électriquement par le connecteur électrique de la base de recharge 100 et le corps chauffant 3 monte rapidement en température grâce à la puissance importante de la résistance électrique 31. Lorsque la température de la semelle 2 atteint la température de consigne sélectionnée au moyen du bouton de réglage 40, le thermostat 4 s'ouvre et un voyant lumineux s'allume sur le fer à repasser pour indiquer à l'utilisateur que la semelle 2 est à la température de consigne et que le fer à repasser 1 est prêt à être utilisé.When the user wishes to perform an ironing session, he fills the reservoir 13 with water and connects the power cord 101 of the charging base 100 to the domestic electrical network, leaving the iron 1 connected to the base of the The resistor 31 of the heating body 3 is then electrically powered by the electrical connector of the base of recharge 100 and the heating body 3 rises rapidly in temperature due to the high power of the electrical resistance 31. When the temperature of the sole 2 reaches the set temperature selected by means of the adjustment knob 40, the thermostat 4 opens and an indicator light on the iron to indicate to the user that the sole 2 is at the set temperature and that the iron 1 is ready to use.

Si l'utilisateur souhaite repasser avec de la vapeur, il lui suffit de presser sur la gâchette 60 de manière à déplacer le clapet obturateur 6 vers la position ouverte, illustrée sur la figure 7, de manière à ce que l'eau en provenance du réservoir 13 se trouvant dans la première portion 13B du circuit d'alimentation puisse s'écouler dans une deuxième portion 13D du circuit d'alimentation s'étendant entre le clapet obturateur 6 et le boisseau goutte-à-goutte 5, l'eau de la deuxième portion 13D s'écoulant dans la chambre de vaporisation 32 avec un débit défini par la position du boisseau goutte-à-goutte 5, c'est-à-dire déterminé automatiquement par la position du bouton de réglage 40 du thermostat 4 afin d'être en adéquation avec la température de consigne de la semelle 2.If the user wishes to iron with steam, it suffices to press the trigger 60 so as to move the shutter valve 6 to the open position, illustrated on the figure 7 , so that the water coming from the tank 13 in the first portion 13B of the supply circuit can flow into a second portion 13D of the supply circuit extending between the shutter valve 6 and the drip plug 5, the water of the second portion 13D flowing into the vaporization chamber 32 with a flow rate defined by the position of the drip plug 5, that is to say automatically determined by the position of the adjustment knob 40 of the thermostat 4 in order to be in adequacy with the temperature set point of the soleplate 2.

Lorsque l'utilisateur relâche la gâchette 60, par exemple pour repositionner le linge ou lorsque le fer à repasser 1 est disposé sur sa base de recharge 100, la gâchette 60 et le clapet obturateur 6 retournent automatiquement en position fermée sous l'effet combiné des ressorts de rappel 61, 64 de la gâchette 60 et de la tige d'actionnement 62 de sorte que l'eau ne peut plus s'écouler au travers de l'orifice de passage 15A, la deuxième portion 13D du circuit d'alimentation n'étant alors plus alimentée en eau par le réservoir 13. Il s'ensuit une interruption de la production de vapeur par la chambre de vaporisation 32, cette dernière n'étant plus alimentée en eau par le circuit d'alimentation.When the user releases the trigger 60, for example to reposition the laundry or when the iron 1 is disposed on its charging base 100, the trigger 60 and the shutter valve 6 automatically return to the closed position under the combined effect of return springs 61, 64 of the trigger 60 and the actuating rod 62 so that water can no longer flow through the passage opening 15A, the second portion 13D of the supply circuit it is then more supplied with water by the tank 13. It follows an interruption of the production of steam by the vaporization chamber 32, the latter being no longer supplied with water by the supply circuit.

Afin d'obtenir une interruption de la vapeur qui soit sensiblement simultanée avec le relâchement de la gâchette 60, la deuxième portion 13D du circuit d'alimentation de la chambre de vaporisation 32 est préférentiellement rendue étanche à l'air en disposant un joint d'étanchéité 54 entre la tige 50 du boisseau goutte-à-goutte et le manchon de guidage 12 de manière à ce que l'écoulement de l'eau stockée dans la deuxième portion 13D du circuit d'alimentation s'interrompt immédiatement à la fermeture du clapet obturateur 6.In order to obtain an interruption of the steam that is substantially simultaneous with the release of the trigger 60, the second portion 13D of the supply circuit of the vaporization chamber 32 is preferably made airtight by having a seal of sealing 54 between the rod 50 of the drip and the guide sleeve 12 so that the flow of water stored in the second portion 13D of the supply circuit stops immediately upon closure of the shutter valve 6.

Si l'utilisateur souhaite obtenir un surplus de vapeur momentané, par exemple pour la réalisation de travaux difficiles, il lui suffit d'actionner la première pompe 8 en appuyant sur le bouton 80 de manière à ce qu'une quantité d'eau prédéterminée, de l'ordre de quelques millilitres, soit envoyée dans la chambre de vaporisation secondaire 33 afin d'obtenir une émission de vapeur supplémentaire, cette vapeur se diffusant au travers d'un nombre restreint de trous 20 de sortie de vapeur situés à l'avant de la semelle 2. Un spray d'eau est également à la disposition de l'utilisateur pour humidifier le linge, ce spray pouvant être obtenu à tout moment au travers de la buse 92 en actionnant manuellement la deuxième pompe 9 en pressant sur le bouton 90.If the user wishes to obtain a momentary surplus of steam, for example to carry out difficult work, it suffices to actuate the first pump 8 by pressing the button 80 so that a predetermined amount of water, of the order of a few milliliters, is sent to the secondary vaporization chamber 33 to obtain an additional vapor emission, this vapor diffusing through a small number of steam outlet holes 20 located at the front the sole 2. A spray of water is also available to the user to moisten the laundry, this spray can be obtained at any time through the nozzle 92 by manually operating the second pump 9 by pressing the button 90.

Lorsque l'utilisateur effectue une séance de repassage relativement longue, supérieure à une minute, avec un fort débit de vapeur sans reposer le fer à repasser 1 sur sa base de recharge 100, la température du corps chauffant 3 va progressivement chuter jusqu'à ce que la température de la chambre de vaporisation 32 ne permette plus la production de vapeur.When the user performs a relatively long ironing session, greater than one minute, with a high flow of steam without resting the iron 1 on its charging base 100, the temperature of the heating body 3 will gradually drop until that the temperature of the vaporization chamber 32 no longer allows the production of steam.

Dans ce cas, peu de temps avant d'atteindre cette température limite ne permettant plus la vaporisation, le bilame 72 va se déformer et entraîner la fermeture de la vanne anti-goutte 7, ainsi que cela est illustré sur la figure 8, de sorte que seule la faible quantité d'eau présente dans les première portion 13B et seconde portion 13D du circuit d'alimentation pourra s'écouler dans la chambre de vaporisation 32 empêchant ainsi que des gouttes d'eau ne s'écoulent par les trous 20 de sortie de la semelle. De plus, la fermeture de la vanne anti-goutte 7 empêche également qu'une importante quantité d'eau ne soit envoyée vers la chambre de vaporisation secondaire 33 pour la production de survapeur si l'utilisateur actionne plusieurs fois le bouton 80 étant donné que seule la faible quantité d'eau éventuellement présente dans la première portion 13B du circuit d'alimentation peut être pompée.In this case, shortly before reaching this limit temperature no longer allowing the vaporization, the bimetallic strip 72 will deform and cause the closing of the anti-drip valve 7, as is illustrated in FIG. figure 8 , so that only the small amount of water present in the first portion 13B and second portion 13D of the feed circuit can flow into the vaporization chamber 32 thus preventing water drops from flowing through them. holes 20 out of the sole. In addition, the closing of the anti-drip valve 7 also prevents a large quantity of water is sent to the secondary vaporization chamber 33 for the production of a steamer if the user actuates the button 80 several times since only the small amount of water possibly present in the first portion 13B of the feed circuit can be pumped.

Bien entendu, le fer à repasser pourra également comporter, en complément des solutions mécaniques décrites ci-dessus, des indicateurs visuels ou sonores, tels par exemple un voyant clignotant, qui seront activés afin d'alerter l'utilisateur sur la nécessité de reposer le fer à repasser 1 sur sa base de recharge 100 lorsque la température du corps chauffant 3 devient insuffisante pour effectuer efficacement les travaux de repassage.Of course, the iron may also include, in addition to the mechanical solutions described above, visual indicators or sound, such as a flashing light, which will be activated to alert the user to the need to rest the iron 1 on its base recharge 100 when the temperature of the heating body 3 becomes insufficient to effectively perform the ironing work.

L'appareil de repassage ainsi réalisé présente l'avantage de posséder un fer à repasser à vapeur sans fil pouvant produire un fort débit de vapeur, supérieur à 30 g/mn, tout en conservant une bonne autonomie d'utilisation entre les phases de recharge sur la base grâce à la présence de la gâchette qui permet d'augmenter l'autonomie et à la présence d'une masse importante d'aluminium embarquée dans le fer qui permet de stocker une grande quantité d'énergie lors des phases inactives de repassage pendant lesquelles le fer à repasser est disposé sur le socle de la base de recharge. De plus, le fait que le fer à repasser comporte une extrémité arrière arrondie sur laquelle il ne peut reposer verticalement présente l'avantage d'inciter l'utilisateur à reposer le fer à repasser sur sa base de recharge lors de phases inactives de repassage.The ironing apparatus thus produced has the advantage of having a cordless steam iron which can produce a high steam flow, greater than 30 g / min, while maintaining a good autonomy of use between the charging phases. on the base thanks to the presence of the trigger that increases the autonomy and the presence of a large mass of aluminum embedded in the iron that can store a large amount of energy during inactive phases of ironing during which the iron is placed on the base of the charging base. In addition, the fact that the iron has a rounded rear end on which it can not stand vertically has the advantage of encouraging the user to rest the iron on its charging base during inactive ironing phases.

Enfin, l'appareil de repassage ainsi réalisé présente l'avantage de posséder une bonne ergonomie d'utilisation limitant la fatigue lors des séances de repassage, malgré le poids important du fer à repasser, grâce à la possibilité d'engager et de sortir le fer à repasser sur le socle sans avoir à soulever le fer mais en le faisant simplement glisser de la table à repasser vers l'une quelconque des rampes d'accès du socle par un simple effort de traction sur la poignée, la présence de rampes d'accès suivant différentes directions permettant d'offrir une grande liberté de mouvement lors de l'accostage du fer sur la base de recharge et offrant un grand choix dans l'orientation de la base de recharge sur la planche à repasser.Finally, the ironing apparatus thus produced has the advantage of having good ergonomics of use limiting fatigue during ironing sessions, despite the significant weight of the iron, thanks to the ability to engage and release the iron on the base without having to lift the iron but simply by sliding it from the ironing board to any of the access ramps of the base by a simple pulling force on the handle, the presence of ramps access in different directions to provide great freedom of movement when docking the iron on the charging base and offering a wide choice in the orientation of the charging base on the ironing board.

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

Ainsi, dans une variante de réalisation de l'invention, la fonderie du corps chauffant pourra être réalisée en magnésium ou dans un alliage comportant de l'aluminium, du cuivre et du magnésium.Thus, in an alternative embodiment of the invention, the foundry of the heating body may be made of magnesium or an alloy comprising aluminum, copper and magnesium.
