FER A VAPEUR AVEC DISPOSITIF ANTI-GOUTTE STEAM IRON WITH ANTI-DRIP DEVICE
DOMAINE TECHNIQUE La présente invention se rapporte au domaine technique général des appareils conçus pour assurer la mise en forme d'un article textile tel qu'un vêtement, en le soumettant à l'action combinée d'un traitement thermique, d'un traitement mécanique et d'un traitement à la vapeur.TECHNICAL FIELD The present invention relates to the general technical field of apparatuses designed to ensure the shaping of a textile article such as a garment, by subjecting it to the combined action of a heat treatment, of a mechanical treatment. and steam treatment.
La présente invention concerne un fer à repasser électrique comprenant une semelle comportant des trous de sortie de vapeur reliés à une chambre de vaporisation mise en température par l'intermédiaire d'un circuit de chauffe en relation thermique avec un dispositif de régulation ou de contrôle de la température, ladite chambre communiquant avec un réservoir d'eau par un orifice susceptible d'être obturé par un boisseau, ledit boisseau permettant de contrôler l'admission de l'eau du réservoir dans la chambre de vaporisation.The present invention relates to an electric iron comprising a soleplate comprising steam outlet holes connected to a vaporization chamber brought to temperature by means of a heating circuit in thermal relation with a device for regulating or controlling the temperature, said chamber communicating with a water tank through an orifice capable of being closed by a plug, said plug making it possible to control the admission of water from the tank into the vaporization chamber.
TECHNIQUE ANTERIEUREPRIOR ART
Il est connu de réaliser un fer à repasser comportant un boisseau extractible. Cette disposition offre l'avantage de pouvoir nettoyer aisément le boisseau, et ainsi de lutter contre l'entartrage. Il est également connu de réaliser un fer à repasser dans lequel le boisseau peut être manœuvré par l'intermédiaire d'un organe de commande pour occuper au moins une position de vaporisation, dans laquelle le boisseau libère au moins partiellement l'orifice reliant le réservoir à la chambre de vaporisation, et une position à sec, dans laquelle le boisseau obture l'orifice reliant le réservoir à la chambre de vaporisation. Un fer comportant plusieurs positions de vaporisation se différenciant par le débit d'eau admis dans la chambre de vaporisation offre l'avantage de permettre à l'utilisateur de régler la quantité de vapeur émise, pour l'adapter par exemple à l'état froissé ou peu froissé de l'article ou à la nature du tissu à repasser. Une telle disposition présente cependant l'inconvénient de laisser s'écouler de l'eau à travers les trous de la semelle lorsque la température de la chambre de vaporisation est insuffisante pour vaporiser toute l'eau admise dans ladite chambre, par exemple lors du repassage d'un article délicat demandant des températures de semelle peu élevées, et pour lequel le thermostat de l'appareil a été réglé à une température de consigne basse. Une telle disposition présente également l'inconvénient de d'obliger l'utilisateur à régler en fonction de la nature du tissu à repasser à la fois le thermostat de l'appareil et la quantité d'eau admise dans la chambre de vaporisation, pour éviter que des gouttes d'eau non vaporisée sortent par les trous de la semelle.It is known to produce an iron comprising an extractable plug. This arrangement offers the advantage of being able to easily clean the plug, and thus to fight against scaling. It is also known to produce an iron in which the plug can be operated by means of a control member to occupy at least one spraying position, in which the plug at least partially frees the orifice connecting the reservoir. to the vaporization chamber, and a dry position, in which the plug plugs the orifice connecting the reservoir to the vaporization chamber. An iron with several vaporization positions differentiated by the flow of water admitted into the vaporization chamber offers the advantage of allowing the user to adjust the quantity of vapor emitted, to adapt it for example to the crumpled state or slightly wrinkled of the article or the nature of the fabric to be ironed. However, such an arrangement has the disadvantage of allowing water to flow through the holes in the soleplate. when the temperature of the vaporization chamber is insufficient to vaporize all the water admitted into said chamber, for example when ironing a delicate article requiring low soleplate temperatures, and for which the thermostat of the appliance has been set to a low set temperature. Such an arrangement also has the disadvantage of forcing the user to adjust according to the nature of the fabric to be ironed both the thermostat of the device and the amount of water admitted into the vaporization chamber, to avoid that drops of unvaporized water come out of the holes in the soleplate.

Le corps 18 disposé dans le logement 22 est susceptible d'occuper une première position dans laquelle l'orifice 16 est obturé par la tige 5 et une deuxième position dans laquelle le bimétal 1 est susceptible de déplacer en fonction de sa température la tige 5 par l'intermédiaire du support 3.The body 18 disposed in the housing 22 is capable of occupying a first position in which the orifice 16 is closed by the rod 5 and a second position in which the bimetal 1 is capable of displacing the rod 5 as a function of its temperature. through the support 3.
Les figures 5 et 6 représentent un fer dans lequel le corps 18 occupe une première position, dite position de vaporisation. La figure 5 représente un fer dans lequel la chambre de vaporisation 14 est à basse température et n'est pas susceptible de vaporiser l'eau qui serait admise dans ladite chambre. Le bilame 1 occupe une position dans laquelle la tige 5 repose sur le support 3 et obstrue l'orifice au droit du joint d'ajutage 7. Ainsi lorsque le fer est en position de vaporisation l'eau n'est pas admise dans la chambre de vaporisation 14 lorsque celle-ci est trop froide pour vaporiser l'eau, et ne risque pas de goutter à travers les trous 12. La figure 6 représente un fer dans lequel la chambre de vaporisation 14 a atteint la température de travail pour laquelle toute l'eau admise dans ladite chambre est vaporisée. Le bilame 1 occupe une position dans laquelle la tige 5 repose sur le support 3 et la gorge 6 se trouve au droit du joint d'ajutage 7, permettant l'admission de l'eau dans la chambre de vaporisation 14. Ainsi lorsque le fer est en position de vaporisation l'eau admise dans la chambre de vaporisation 14 est entièrement vaporisée et ne goutte pas à travers les trous 12. La tige 5 mobile par rapport au corps 18 suit le déplacement du support 3 actionné par le bilame 1.Figures 5 and 6 show an iron in which the body 18 occupies a first position, called the vaporization position. FIG. 5 represents an iron in which the vaporization chamber 14 is at low temperature and is not not likely to vaporize the water which would be admitted in said room. The bimetallic strip 1 occupies a position in which the rod 5 rests on the support 3 and obstructs the orifice to the right of the nozzle joint 7. Thus when the iron is in the vaporization position water is not admitted into the chamber vaporization 14 when it is too cold to vaporize the water, and is not likely to drip through the holes 12. Figure 6 shows an iron in which the vaporization chamber 14 has reached the working temperature for which all the water admitted to said chamber is vaporized. The bimetallic strip 1 occupies a position in which the rod 5 rests on the support 3 and the groove 6 is located in line with the nozzle joint 7, allowing the admission of water into the vaporization chamber 14. Thus when the iron is in the vaporization position the water admitted into the vaporization chamber 14 is entirely vaporized and does not drip through the holes 12. The rod 5 movable relative to the body 18 follows the movement of the support 3 actuated by the bimetallic strip 1.
Les figures 7 et 8 représentent un fer dans lequel le corps 18 occupe une deuxième position, dite position à sec. Dans cette position la tige 5 obture l'orifice au droit du joint d'ajutage 7. La figure 7 représente un fer dans lequel la chambre de vaporisation 14 est à basse température et la figure 8 représente un fer dans lequel la chambre de vaporisation 14 a atteint la température de travail. Quelle que soit la température régnant dans la chambre de vaporisation 14, entre la température ambiante et la température maximale atteinte par le fer en usage normal, le déplacement éventuel du support 3 par le bilame 1 laisse toujours une partie 36 de la tige 5 au droit du joint d'ajutage 7. Tel que représenté aux figures, le support 3 est maintenu en place par la tige 5, par exemple par un léger serrage. Selon une variante de réalisation, non représentée aux figures, le support 3 repose sur le bilame 1. Selon l'exemple de réalisation montré à la figure 8 la tige 5 est maintenue par des moyens de butée tels que l'ergot 25 en appui sur l'extrémité de la lumière 23, sous l'action du ressort de rappel 26. Le fer comporte des moyens 40 permettant de manœuvrer le corps 18 de la position à sec à la position de vaporisation et vice-versa, et aussi d'extraire le boisseau 17. L'utilisateur dispose ainsi d'un appareil perfectionné permettant de choisir entre un repassage à sec et un repassage avec de la vapeur, en ayant de plus la garantie que de l'eau ne s'écoule pas des trous 12 lors d'un repassage en position de vaporisation. Le fer à vapeur ainsi réalisé dispose d'un dispositif anti-goutte, compatible avec l'extraction du boisseau.Figures 7 and 8 show an iron in which the body 18 occupies a second position, called the dry position. In this position, the rod 5 closes the orifice to the right of the nozzle joint 7. FIG. 7 represents an iron in which the vaporization chamber 14 is at low temperature and FIG. 8 represents an iron in which the vaporization chamber 14 has reached working temperature. Whatever the temperature prevailing in the vaporization chamber 14, between ambient temperature and the maximum temperature reached by the iron in normal use, the possible displacement of the support 3 by the bimetallic strip 1 always leaves part 36 of the rod 5 at right of the nozzle joint 7. As shown in the figures, the support 3 is held in place by the rod 5, for example by slight tightening. According to an alternative embodiment, not shown in the figures, the support 3 rests on the bimetal strip 1. According to the exemplary embodiment shown in FIG. 8 the rod 5 is held by stop means such as the lug 25 resting on the end of the light 23, under the action of the return spring 26. The iron comprises means 40 making it possible to maneuver the body 18 from the dry position to the spraying position and vice-versa, and also to extract the plug 17. The user thus has an improved device making it possible to choose between dry ironing and ironing with steam, further ensuring that water does not flow from the holes 12 during ironing in the spray position. The steam iron thus produced has an anti-drip device, compatible with extracting the plug.
Selon une version avantageuse de l'invention, représentée à la figure 9, la section de la gorge 6 augmente avec la distance à l'extrémité libre 21 de la tige 5. La déflexion du bilame 1 augmentant avec la température, la section de la gorge 6 disposée en regard du joint d'ajutage 7 augmente avec la température. Ainsi plus la température régnant dans la chambre de vaporisation 14 est élevée, plus le débit d'eau issu du réservoir 15 est important, et plus le débit de vapeur sortant par les trous 12 est important. Cette disposition est intéressante car les articles les plus délicats sont repassés à faible température et ne nécessitent pas un débit important de vapeur alors que les articles plus épais et plus résistants, repassés à plus haute température, nécessitent un débit important de vapeur. Cette disposition permet de réaliser un fer à vapeur avec un dispositif anti-goutte dont le débit de vapeur varie avec la température de la chambre de vaporisation.According to an advantageous version of the invention, represented in FIG. 9, the section of the groove 6 increases with the distance from the free end 21 of the rod 5. The deflection of the bimetallic strip 1 increases with temperature, the section of the groove 6 disposed opposite the nozzle joint 7 increases with temperature. Thus, the higher the temperature prevailing in the vaporization chamber 14, the greater the flow of water from the reservoir 15, and the greater the flow of steam exiting through the holes 12. This arrangement is advantageous because the most delicate articles are ironed at low temperature and do not require a large flow of steam while the thicker and more resistant articles, ironed at higher temperature, require a large flow of steam. This arrangement makes it possible to produce a steam iron with an anti-drip device whose vapor flow rate varies with the temperature of the vaporization chamber.
Selon une version encore plus avantageuse de l'invention, le corps 18 est susceptible d'occuper plusieurs positions dans lesquelles le bimétal 1 est susceptible de déplacer en fonction de sa température la tige 5 par l'intermédiaire du support 3. La figure 10 présente un fer selon l'invention dans lequel le corps 18 occupe une position intermédiaire entre la position à sec et la position de vaporisation. Dans une position telle que cette position intermédiaire, la température de la chambre de vaporisation 14 à partir de laquelle le bilame 1 déplace le support 3 de manière à amener la gorge 6 de la tige 5 en regard du joint d'ajutage 7 est supérieure à la température de la chambre de vaporisation pour laquelle cette disposition intervient lorsque le corps occupe la position de vaporisation. Lorsque la section de la gorge 6 augmente avec la distance à l'extrémité libre 21 de la tige 5, la quantité d'eau admise à température de la chambre de vaporisation identique est plus grande dans la position de vaporisation que dans la position intermédiaire. Cette disposition permet de réaliser un fer à vapeur avec un dispositif anti-goutte et plusieurs débits de vapeur.According to an even more advantageous version of the invention, the body 18 is capable of occupying several positions in which the bimetal 1 is capable of displacing, as a function of its temperature, the rod 5 via the support 3. FIG. 10 shows an iron according to the invention in which the body 18 occupies an intermediate position between the dry position and the spraying position. In a position such as this intermediate position, the temperature of the vaporization chamber 14 from which the bimetallic strip 1 moves the support 3 so as to bring the groove 6 of the rod 5 opposite the nozzle joint 7 is greater than the temperature of the vaporization chamber for which this arrangement occurs when the body occupies the vaporization position. When the section of the groove 6 increases with the distance from the free end 21 of the rod 5, the quantity of water admitted at the same temperature of the vaporization chamber is greater in the vaporization position than in the intermediate position. This arrangement makes it possible to produce a steam iron with an anti-drip device and several steam flow rates.
L'invention s'applique également à des fers à repasser comportant plusieurs moyens de chauffe, par exemple un moyen de chauffe prévu pour chauffer préfèrentiellement la semelle 11 , et un moyen de chauffe prévu pour chauffer préfèrentiellement la chambre de vaporisation 14.The invention also applies to irons comprising several heating means, for example a heating means provided for heating preferably the sole 11, and a heating means provided for heating preferably the vaporization chamber 14.
POSSIBILITE D'APPLICATION INDUSTRIELLE L'invention trouve son application dans le domaine technique des fers à repasser électriques à vapeur. POSSIBILITY OF INDUSTRIAL APPLICATION The invention finds its application in the technical field of electric steam irons.
