Description

FER COMPORTANT DEUX MOYENS DE CHAUFFE AVEC UN MODE D'ASSERVISSEMENT EN TEMPERATURE PARTICULIER IRON COMPRISING TWO MEANS OF HEATING WITH A SPECIAL TEMPERATURE DELIVERY MODE
DOMAINE TECHNIQUETECHNICAL AREA
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 de repassage et d'un traitement à la vapeur.The present invention relates to the general technical field of devices designed to ensure the shaping of a textile article such as a garment, by subjecting it to the combined action of a heat treatment, a mechanical ironing treatment. and steam treatment.
La présente invention concerne un fer à repasser électrique comprenant une partie chaude constituée d'une semelle et d'une chambre de vaporisation pour lesquelles la mise en température est assurée par l'intermédiaire d'un circuit de chauffe en relation thermique avec un dispositif de régulation ou de contrôle de la température.The present invention relates to an electric iron comprising a hot part consisting of a soleplate and a vaporization chamber for which the temperature is ensured by means of a heating circuit in thermal relation with a device for temperature regulation or control.
La présente invention concerne également un procédé de régulation d'un fer électrique à vapeur.The present invention also relates to a method for regulating an electric steam iron.
TECHNIQUE ANTERIEUREPRIOR ART
Les fers à vapeurs connus de l'art antérieur comportent généralement un élément chauffant en relation thermique avec une chambre de vaporisation, par exemple un élément chauffant tubulaire moulé dans la fonderie de ladite chambre, ledit élément chauffant étant associé à des moyens de régulation, lesquels sont fixés le plus souvent sur la fonderie. Cette construction traditionnelle présente plusieurs inconvénients. Lorsque la température de consigne des moyens de régulation est fixée à une valeur peu élevée, afin d'obtenir une température de semelle basse, dans le but par exemple de repasser des articles en tissu délicat, ne supportant pas les températures élevées, la température régnant dans la chambre de vaporisation est insuffisante pour vaporiser l'eau introduite dans ladite chambre. Cette situation est gênante puisqu'elle ne permet pas de bénéficier d'une production de vapeur lors du repassage d'articles délicats. Lorsque la température de consigne des moyens de régulation est fixée à une valeur élevée, afin d'obtenir une température de semelle élevée et de préférence un débit de vapeur important, dans le but par exemple de repasser des articles résistants, il est connu et mis en évidence par des thermographies que la partie de la semelle se situant sous la chambre de vaporisation est sensiblement plus froide que le reste de la surface de la semelle, en particulier pendant l'opération de vaporisation. Cette situation est gênante puisqu'on souhaite en général que la surface de la semelle du fer atteigne sa température optimale au moment où la vapeur est émise.Steam irons known from the prior art generally comprise a heating element in thermal relation with a vaporization chamber, for example a tubular heating element molded in the foundry of said chamber, said heating element being associated with regulation means, which are most often attached to the foundry. This traditional construction has several drawbacks. When the setpoint temperature of the regulating means is fixed at a low value, in order to obtain a low soleplate temperature, with the aim for example of ironing delicate fabric articles, not tolerating high temperatures, the prevailing temperature in the vaporization chamber is insufficient to vaporize the water introduced into said chamber. This situation is troublesome since it does not allow the production of steam when ironing delicate items. When the setpoint temperature of the regulating means is fixed at a high value, in order to obtain a high soleplate temperature and preferably a high vapor flow rate, in order for example to iron resistant articles, it is known and put demonstrated by thermography that the part of the sole located under the vaporization chamber is significantly cooler than the rest of the surface of the sole, in particular during the vaporization operation. This situation is troublesome since it is generally desired that the surface of the soleplate of the iron reaches its optimum temperature at the time when the steam is emitted.
Il est connu du document US 3 110 975 de réaliser un fer à repasser à vapeur comprenant une partie chaude comportant une semelle et une chambre de vaporisation, la semelle et la chambre de vaporisation formant chacune une zone thermique dotée d'un élément chauffant associé à des moyens de régulation, la semelle et la chambre de vaporisation étant isolées thermiquement l'une par rapport à l'autre. Lors du repassage de textiles délicats il est ainsi possible d'obtenir dans la chambre de vaporisation une température suffisante pour la vaporisation de l'eau, tout en conservant une température de semelle suffisamment basse pour ne pas détériorer l'article à repasser.It is known from document US Pat. No. 3,110,975 to produce a steam iron comprising a hot part comprising a soleplate and a vaporization chamber, the soleplate and the vaporization chamber each forming a thermal zone provided with a heating element associated with regulating means, the soleplate and the vaporization chamber being thermally insulated from one another. When ironing delicate textiles, it is thus possible to obtain in the vaporization chamber a temperature sufficient for the vaporization of water, while keeping a soleplate temperature sufficiently low so as not to damage the article to be ironed.
Cette réalisation présente l'inconvénient de comporter deux moyens de chauffe distincts associés chacun à des moyens de régulation propres. Il en résulte que cette construction est onéreuse, et encombrante, puisqu'il y a deux moyens de régulation et que ceux-ci doivent être disposés aux endroits appropriés.This embodiment has the drawback of comprising two separate heating means each associated with its own regulation means. It follows that this construction is expensive, and bulky, since there are two means of regulation and that these must be arranged in the appropriate places.
Il est connu du document FR 2 727 439 de réaliser un fer à repasser à vapeur comprenant une partie chaude comportant une semelle et une chambre de vaporisation, la partie chaude étant divisée en au moins deux zones thermiques, chacune d'elles étant dotée d'un élément chauffant, une première zone comprenant au moins une surface correspondant sensiblement à la chambre de vaporisation, une seconde zone correspondant au moins une surface correspondant sensiblement à la portion de semelle située sous la chambre, l'élément chauffant de la première zone étant associé à un organe de régulation disposé dans ladite zone, l'élément chauffant de la seconde zone étant associé à un organe de régulation disposé dans ladite zone, la première zone et la seconde zone étant en relation thermique l'une par rapport à l'autre, l'élément chauffant associé à la première zone étant prévu pour assurer partiellement le chauffage de la seconde zone. Lors du repassage d'articles demandant de grandes quantités de vapeur, l'élément chauffant de la seconde zone permet de prévenir la formation d'une zone froide de la semelle sous la chambre de vaporisation. Le repassage est ainsi plus efficace.It is known from document FR 2 727 439 to produce a steam iron comprising a hot part comprising a soleplate and a vaporization chamber, the hot part being divided into at least two thermal zones, each of which is provided with a heating element, a first zone comprising at least one surface corresponding substantially to the vaporization chamber, a second zone corresponding to at least one surface corresponding substantially to the sole portion located under the chamber, the heating element of the first zone being associated with a regulating member disposed in said zone, the heating element of the second zone being associated with a regulating member disposed in said zone, the first zone and the second zone being in thermal relation to each other, the associated heating element the first zone being provided to partially heat the second zone. When ironing items requiring large amounts of steam, the heating element in the second zone prevents the formation of a cold zone in the soleplate under the vaporization chamber. Ironing is therefore more efficient.
Cette réalisation présente également l'inconvénient de comporter deux moyens de chauffe distincts associés chacun à des moyens de régulation propres. Cette réalisation est donc onéreuse. De plus, afin de limiter la température de la semelle en vue de repasser des textiles délicats, la maîtrise du transfert thermique entre la semelle et la fonderie de la chambre de vaporisation requiert une diminution de la surface d'échange entre la semelle et la fonderie, ce qui rend difficile l'étanchéité et la tenue mécanique de la semelle.This embodiment also has the drawback of comprising two separate heating means each associated with its own regulation means. This realization is therefore expensive. In addition, in order to limit the temperature of the soleplate in order to iron delicate textiles, controlling the heat transfer between the soleplate and the foundry of the vaporization chamber requires a reduction in the exchange surface between the soleplate and the foundry. , which makes sealing and mechanical resistance of the sole difficult.
Pour toutes les raisons précédemment exposées les réalisations précitées ne sont pas satisfaisantes.For all the reasons explained above, the above-mentioned embodiments are not satisfactory.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
Le but de l'invention est donc de réaliser un fer à repasser à vapeur permettant de repasser de manière efficace les tissus épais ou résistants demandant un débit de vapeur important, et permettant de repasser les tissus délicats en produisant de la vapeur sans risquer de les détériorer, tout en présentant une construction simple et économique. Bien entendu l'invention s'applique également aux fers à repasser comportant un réservoir intégré, comme aux fers à repasser comportant un réservoir extérieur séparé.The object of the invention is therefore to produce a steam iron which makes it possible to iron thick or resistant fabrics effectively requiring a high steam flow rate, and which makes it possible to iron delicate fabrics by producing steam without risking them. deteriorate, while presenting a simple and economical construction. Of course, the invention also applies to irons comprising an integrated reservoir, such as to irons comprising a separate external reservoir.
Les buts de l'invention sont atteints par un fer à repasser électrique à vapeur, comprenant une partie chaude comportant une semelle et une chambre de vaporisation, la partie chaude du fer étant divisée en deux zones thermiques, une première zone correspondant sensiblement à la chambre de vaporisation étant dotée de premiers moyens de chauffe, une seconde zone correspondant sensiblement à une portion de la semelle disposée sous la chambre de vaporisation étant dotée de seconds moyens de chauffe, les premiers moyens de chauffe étant associés à un organe de régulation disposé dans ladite première zone, les premiers moyens de chauffe étant prévus pour assurer partiellement le chauffage de la seconde zone, caractérisé en ce que les seconds moyens de chauffe sont associés à l'organe de régulation de la première zone.The objects of the invention are achieved by an electric steam iron, comprising a hot part comprising a soleplate and a vaporization chamber, the hot part of the iron being divided into two thermal zones, a first zone corresponding substantially to the chamber. vaporizer being provided with first heating means, a second zone corresponding substantially to a portion of the sole disposed under the vaporization chamber being provided with second heating means, the first heating means being associated with a regulating member disposed in said first zone, the first heating means being provided for partially heating the second zone, characterized in that the second heating means are associated with the regulating member of the first zone.
Le fer ainsi obtenu est d'une conception simplifiée puisqu'il ne comporte qu'un seul organe de régulation. La puissance des seconds moyens de chauffe doit bien entendue être choisie de manière à ne pas détériorer l'article à repasser. Pour des puissances des seconds moyens de chauffe choisies de manière à compenser plus que la chute de température de la semelle due à la vaporisation de l'eau dans la chambre de vaporisation, cette disposition permet d'obtenir des températures de semelle plus élevées lorsque de l'eau est introduite dans la chambre de vaporisation et ainsi de mieux assécher les articles difficiles à repasser demandant beaucoup de vapeur. Les articles délicats demandant des températures de repassage peu élevées ne nécessitant pas beaucoup de vapeur, la présente invention permet d'obtenir avec une construction peu onéreuse un asservissement des moyens de chauffe particulièrement adapté au repassage des différentes catégories d'articles.The iron thus obtained is of a simplified design since it comprises only one regulating member. The power of the second heating means must of course be chosen so as not to damage the article to be ironed. For powers of the second heating means chosen so as to compensate more than the drop in temperature of the soleplate due to the vaporization of the water in the vaporization chamber, this arrangement makes it possible to obtain higher soleplate temperatures when water is introduced into the vaporization chamber and thus better drying items that are difficult to iron requiring a lot of steam. Delicate articles requiring low ironing temperatures not requiring a lot of steam, the present invention makes it possible to obtain, with an inexpensive construction, a control of the heating means particularly suitable for ironing the various categories of articles.
Avantageusement les seconds moyens de chauffe sont formés par un élément chauffant plat. L'encombrement du fer est ainsi sensiblement réduit, grâce à la faible épaisseur de l'élément chauffant plat. De plus le chauffage de la semelle est plus homogène, l'élément chauffant plat procurant un chauffage sur une surface.Advantageously, the second heating means are formed by a flat heating element. The size of the iron is thus significantly reduced, thanks to the small thickness of the flat heating element. In addition, the heating of the sole is more homogeneous, the flat heating element providing heating on a surface.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION
Un exemple de réalisation d'un fer à repasser électrique à vapeur selon l'invention est représenté à la figure 1. Le fer selon l'invention comprend une partie chaude comportant une semelle 1 et une chambre de vaporisation 2. La partie chaude du fer est divisée en deux zones thermiques. La première zone thermique correspond sensiblement à la chambre de vaporisation 2, et est dotée de premiers moyens de chauffe 3. La seconde zone thermique correspond sensiblement à une portion de la semelle 1 disposée sous la chambre de vaporisation 2, et est dotée de seconds moyens de chauffe 4. Les premiers moyens de chauffe 3 sont associés à un organe de régulation 5 disposé dans ladite première zone et sont prévus pour assurer partiellement le chauffage de la seconde zone. Tel que représenté à la figure 1 la chambre de vaporisation comporte un corps métallique 22 en matériau bon conducteur de la chaleur, attenant à la semelle 1 , sur lequel est rapporté un couvercle 23. Le corps 22 est fixé de manière connue à la semelle 1 de manière à réaliser une bonne liaison thermique entre ladite semelle et ladite chambre. Tel que représenté à la figure 1 l'organe de régulation 5 est monté sur le couvercle 23.An embodiment of an electric steam iron according to the invention is shown in FIG. 1. The iron according to the invention comprises a hot part comprising a soleplate 1 and a vaporization chamber 2. The hot part of the iron is divided into two thermal zones. The first thermal zone corresponds substantially to the vaporization chamber 2, and is provided with first heating means 3. The second thermal zone corresponds substantially to a portion of the sole 1 disposed under the vaporization chamber 2, and is provided with second means 4. The first heating means 3 are associated with a regulating member 5 disposed in said first zone and are provided for partially heating the second zone. As shown in Figure 1 the vaporization chamber includes a metal body 22 of good heat conductive material, attached to the sole 1, on which is attached a cover 23. The body 22 is fixed in known manner to the sole 1 so as to achieve a good thermal connection between said sole and said chamber. As shown in FIG. 1, the regulating member 5 is mounted on the cover 23.
Selon l'invention les moyens de chauffe 4 de la seconde zone sont associés à l'organe de régulation 5 de la première zone. Cette disposition est rendue possible en choisissant des seconds moyens de chauffe 4 d'une puissance appropriée et avantageusement inférieure à celle des premiers moyens de chauffe 3. L'organe de régulation 5 ferme l'alimentation électrique des premiers moyens de chauffe 3 lorsque la température de la première zone thermique, correspondant sensiblement à la chambre de vaporisation 2, diminue. Cet état intervient peu fréquemment lorsque le fer est utilisé à sec. Il suffit d'ajuster la puissance des premier et deuxième moyens de chauffe 3 ; 4 et le calibrage de l'organe de régulation 5 pour que la température de la semelle 1 soit adaptée au tissu correspondant à une position donnée de l'organe de régulation.According to the invention, the heating means 4 of the second zone are associated with the regulating member 5 of the first zone. This arrangement is made possible by choosing second heating means 4 of an appropriate power and advantageously less than that of the first heating means 3. The regulator 5 closes the electrical supply to the first heating means 3 when the temperature of the first thermal zone, substantially corresponding to the vaporization chamber 2, decreases. This condition occurs infrequently when the iron is used dry. It suffices to adjust the power of the first and second heating means 3; 4 and the calibration of the regulating member 5 so that the temperature of the sole 1 is adapted to the tissue corresponding to a given position of the regulating member.
Lorsque le fer est utilisé en position vapeur, l'eau introduite dans la chambre de vaporisation 2 contribue à refroidir ladite chambre. L'implantation de seconds moyens de chauffe 4 sous la chambre de vaporisation 2 permet de lutter contre la chute de température précitée. Comme les seconds moyens de chauffe 4 sont alimentés lors de la chute de température précitée, le risque de brûler les tissus repassés est limité et même évité en choisissant une puissance appropriée pour lesdits seconds moyens de chauffe 4, par exemple de 70 à 200 W.When the iron is used in the steam position, the water introduced into the vaporization chamber 2 contributes to cooling the said chamber. The installation of second heating means 4 under the vaporization chamber 2 makes it possible to combat the aforementioned drop in temperature. As the second heating means 4 are supplied during the aforementioned drop in temperature, the risk of burning the ironed fabrics is limited and even avoided by choosing an appropriate power for said second heating means 4, for example from 70 to 200 W.
Lorsque l'utilisateur souhaite davantage de vapeur, il augmente l'admission de l'eau dans la chambre de vaporisation 2. L'organe de régulation 5 est sollicité par la diminution de température consécutive à l'admission de l'eau, et agit de façon attendue sur l'alimentation en énergie des premiers moyens de chauffe 3 associés à la chambre de vaporisation 2. La sollicitation de l'organe de régulation 5 agit de manière moins attendue sur les seconds moyens de chauffe 4 associés à la semelle 1. Les seconds moyens de chauffe 4 régulés par l'organe 5 sont en effet davantage alimentés en énergie lorsque de l'eau est admise dans la chambre de vaporisation 2. Il s'ensuit que si les seconds moyens de chauffe 4 ont une puissance suffisante, par exemple supérieure à 70 W, leur alimentation permet de compenser la chute de température intervenant sur la semelle, consécutive à l'admission de l'eau dans la chambre de vaporisation 2. Ainsi le mode d'asservissement en température particulier des moyens de chauffe permet d'obtenir des températures de semelle plus élevées que lors d'un fonctionnement à sec pour un même réglage de l'organe de régulation 5, lorsque de l'eau est admise dans la chambre de vaporisation 2, et d'autant plus élevées que beaucoup d'eau est admise dans ladite chambre. Cette disposition est intéressante car lorsqu'un article est difficile à repasser et demande beaucoup de vapeur, la température plus élevée de la semelle 1 va permettre de mieux assécher ledit article. Bien entendu la puissance des seconds moyens de chauffe 4 doit être choisie de manière à ne pas détériorer l'article à repasser. Une valeur de 200 W permet de rester dans une limite acceptable.When the user wants more steam, he increases the admission of water into the vaporization chamber 2. The regulating member 5 is stressed by the temperature decrease following the admission of water, and acts as expected on the power supply of the first heating means 3 associated with the vaporization chamber 2. The stress on the regulating member 5 acts less expected on the second heating means 4 associated with the sole 1. The second heating means 4 regulated by the member 5 are in fact more supplied with energy when water is admitted into the vaporization chamber 2. It follows that if the second heating means 4 have sufficient power, for example greater than 70 W, their power supply compensates for the drop in temperature occurring on the soleplate, following the admission of water into the vaporization chamber 2. Thus the temperature control mode p specific heating means makes it possible to obtain higher sole temperatures than during dry operation for the same adjustment of the regulating member 5, when water is admitted into the vaporization chamber 2, and all the higher that a lot of water is admitted into said room. This arrangement is advantageous because when an article is difficult to iron and requires a lot of steam, the higher temperature of the sole 1 will allow said article to be better dried. Of course, the power of the second heating means 4 must be chosen so as not to damage the article to be ironed. A value of 200 W makes it possible to stay within an acceptable limit.
Avantageusement les seconds moyens de chauffe 4 sont formés par un élément chauffant plat 6, tel que représenté aux figures 1 , 2a, 2b et 2c. Un tel élément chauffant présente une inertie thermique plus faible que les éléments chauffants tubulaires ou blindés. Cette caractéristique permet de simplifier la régulation car le pic de température dans la seconde zone est atteint peu après voire lors de la coupure de l'alimentation électrique par l'organe de régulation 5. De plus l'élément chauffant plat 6 chauffe une surface de manière sensiblement homogène, si une telle configuration est souhaitée, ou peut être dessiné aisément de manière à apporter les calories dans la zone la plus affectée par la chute de température. Cet élément occupe de préférence une surface relative de 1/6e à 2/5e de la surface totale de la semelle. Bien entendu plusieurs éléments chauffants plats 6 peuvent être connectés en ensemble en série ou en parallèle ou selon toute combinaison de ces deux modes de manière à réaliser la carte thermique souhaitée, sans pour autant sortir du cadre de l'invention.Advantageously, the second heating means 4 are formed by a flat heating element 6, as shown in Figures 1, 2a, 2b and 2c. Such a heating element has a lower thermal inertia than tubular or shielded heating elements. This characteristic makes it possible to simplify the regulation because the temperature peak in the second zone is reached soon after or even when the power supply is cut off by the regulating member 5. In addition, the flat heating element 6 heats a surface of substantially homogeneously, if such a configuration is desired, or can be easily drawn so as to bring the calories into the area most affected by the drop in temperature. This element preferably occupies a relative surface of 1/6 th to 2/5 th of the total surface of the sole. Of course, several flat heating elements 6 can be connected together in series or in parallel or according to any combination of these two modes so as to produce the desired thermal map, without going beyond the ambit of the invention.
Avantageusement les premiers moyens de chauffe 3 sont formés par un élément chauffant tubulaire 7, moulée dans la fonderie formant le corps 22 de la chambre de vaporisation 2, tel que représenté à la figure 1. La puissance de cet élément est de préférence comprise entre 1000 et 2000 W.Advantageously, the first heating means 3 are formed by a tubular heating element 7, molded in the foundry forming the body 22 of the vaporization chamber 2, as shown in FIG. 1. The power of this element is preferably between 1000 and 2000 W.
Selon une disposition avantageuse de la présente invention représentée à la figure 2a, l'élément chauffant tubulaire 7, formant les premiers moyens de chauffe 3, comporte deux branches 8, 9 sensiblement parallèles, raccordées par un coude 10, et entre lesquelles s'étend sensiblement l'élément chauffant plat 6. La géométrie de l'élément chauffant plat 6 n'est nullement limitée à la forme rectangulaire représentée à la figure 2a, mais peut prendre d'autres formes. La figure 2b montre un élément chauffant plat de géométrie suivant au moins en partie la forme des branches 8, 9 de l'élément chauffant tubulaire 7. La figure 2c montre un élément chauffant plat dont la géométrie suit au moins partiellement la forme du fond de la chambre de vaporisation.According to an advantageous arrangement of the present invention shown in Figure 2a, the tubular heating element 7, forming the first heating means 3, comprises two branches 8, 9 substantially parallel, connected by an elbow 10, and between which extends substantially the flat heating element 6. The geometry of the flat heating element 6 is in no way limited to the rectangular shape shown in FIG. 2a, but can take other forms. FIG. 2b shows a flat heating element of geometry following at least in part the shape of the branches 8, 9 of the tubular heating element 7. FIG. 2c shows a flat heating element whose geometry at least partially follows the shape of the bottom of the vaporization chamber.
La figure 2a montre les premiers moyens de chauffe 3 et les seconds moyens de chauffe 4 montés en parallèle et associés à l'organe de régulation 5 disposé dans la première zone thermique.FIG. 2a shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone.
La figure 2b montre également les premiers moyens de chauffe 3 et les seconds moyens de chauffe 4 montés en parallèle et associés à l'organe de régulation 5 disposé dans la première zone thermique. Des premiers moyens de commande 11 permettent de mettre hors circuit les seconds moyens de chauffe 4. Une telle disposition est intéressante notamment pour le repassage de textiles très délicats car elle permet de mieux maîtriser la température de la semelle.FIG. 2b also shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone. First control means 11 make it possible to deactivate the second heating means 4. Such an arrangement is advantageous in particular for ironing very delicate textiles because it allows better control of the temperature of the sole.
La figure 2c montre également les premiers moyens de chauffe 3 et les seconds moyens de chauffe 4 montés en parallèle et associés à l'organe de régulation 5 disposé dans la première zone thermique. Des seconds moyens de commande 12 permettent de court-circuiter l'organe de régulation 5 pour les seconds moyens de chauffe 4. Une connexion électrique 13 montée entre les seconds moyens de chauffe 4 et l'organe de régulation 5 permet la commande des seconds moyens de chauffe 4 par l'organe de régulation 5 lorsque les seconds moyens de commande ne sont pas en position active forçant l'alimentation des seconds moyens de chauffe 4.FIG. 2c also shows the first heating means 3 and the second heating means 4 mounted in parallel and associated with the regulating member 5 disposed in the first thermal zone. Second control means 12 make it possible to short-circuit the regulating member 5 for the second heating means 4. An electrical connection 13 mounted between the second heating means 4 and the regulating member 5 allows the control of the second means 4 by the regulating member 5 when the second control means are not in the active position forcing the supply of the second heating means 4.
A titre de variante, il est possible de prévoir les premiers moyens de commande 11 (non montrés à la figure 2c) sur la connexion électrique 13 ou sur une connexion électrique principale 15 reliant les seconds moyens de chauffe 4 à un point 16 sur lequel sont connectés la connexion 13 et les seconds moyens de commande 12. L'un ou l'autre de ces schémas électriques peuvent être utilisés dans le fer représenté à la figure 3. Les premiers moyens de chauffe 3 et les seconds moyens de chauffe 4 montrés aux figures 2a et 2b sont montés en parallèle. A titre de variante il est possible d'envisager un montage en série des premiers et seconds moyens de chauffe 3, 4. Le montage des moyens de commande 11 des seconds moyens de chauffe 4 doit dans ce cas être modifié pour court-circuiter lesdits moyens 4 au lieu de les mettre hors circuit.Alternatively, it is possible to provide the first control means 11 (not shown in FIG. 2c) on the electrical connection 13 or on a main electrical connection 15 connecting the second heating means 4 to a point 16 on which are connected connection 13 and second control means 12. Either of these electrical diagrams can be used in the iron shown in FIG. 3. The first heating means 3 and the second heating means 4 shown in Figures 2a and 2b are mounted in parallel. As a variant, it is possible to envisage a series connection of the first and second heating means 3, 4. The mounting of the control means 11 of the second heating means 4 must in this case be modified in order to short-circuit said means 4 instead of switching them off.
Les premiers moyens de commande 11 prévus pour mettre hors circuit les seconds moyens de chauffe 4 et les seconds moyens de commande 12 prévus pour forcer l'alimentation des seconds moyens de chauffe 4 peuvent être commandés par l'utilisateur directement ou indirectement.The first control means 11 provided for switching off the second heating means 4 and the second control means 12 provided for forcing the supply of the second heating means 4 can be controlled by the user directly or indirectly.
Le fer représenté de manière schématique à la figure 3 comporte une touche de vaporisation 22 prévue pour être actionnée par l'utilisateur. La touche de vaporisation 22 commande une tige 20 permettant d'ouvrir un orifice 19 prévu pour mettre en communication un réservoir d'eau 18 avec la chambre de vaporisation 2.The iron shown schematically in Figure 3 has a spray button 22 intended to be actuated by the user. The vaporization button 22 controls a rod 20 making it possible to open an orifice 19 provided for placing a water tank 18 in communication with the vaporization chamber 2.
Le fer représenté de manière schématique à la figure 3 comporte également un sélecteur de repassage 21 prévu pour être actionné par l'utilisateur et coopérant avec les premiers moyens de commande 11. Le sélecteur 21 est susceptible d'occuper une position de repassage à sec dans laquelle les premiers moyens de commande 11 désactivent les seconds moyens de chauffe 4, et au moins une position de repassage à la vapeur, dans laquelle les seconds moyens de chauffe 4 sont susceptibles d'être alimentés.The iron shown diagrammatically in FIG. 3 also includes an ironing selector 21 designed to be actuated by the user and cooperating with the first control means 11. The selector 21 is capable of occupying a dry ironing position in which the first control means 11 deactivate the second heating means 4, and at least one steam ironing position, in which the second heating means 4 can be supplied.
Avantageusement le sélecteur 21 est susceptible d'occuper une position grande vapeur, dans laquelle la touche de vaporisation 22 est susceptible de commander les seconds moyens de commande 12 forçant l'alimentation des seconds moyens de chauffe 4, et une position vapeur délicate, dans laquelle la touche de vaporisation 22 ne peut commander les seconds moyens de commande 12 pour l'alimentation des seconds moyens de chauffe 4. La première position est destinée au repassage à la vapeur de textiles difficiles, alors que la seconde position est destinée au repassage à la vapeur de textiles délicats.Advantageously, the selector 21 is capable of occupying a high steam position, in which the spray button 22 is capable of controlling the second control means 12 forcing the supply of the second heating means 4, and a delicate steam position, in which the spray button 22 cannot control the second control means 12 for supplying the second heating means 4. The first position is intended for ironing difficult textiles with steam, while the second position is intended for ironing with textile vapor delicate.
De préférence le sélecteur 21 en position vapeur délicate limite la course de la touche de vaporisation 22. Cette disposition permet d'une part de limiter l'ouverture de l'orifice 19 et par là même la quantité d'eau admise dans la chambre de vaporisation 2, et d'autre part d'empêcher l'actionnement des seconds moyens de commande 12. De préférence le sélecteur 21 en position de repassage à sec bloque la tige 20, directement ou par l'intermédiaire de la touche de vaporisation 22, pour éviter l'admission d'eau dans la chambre de vaporisation 2.Preferably the selector 21 in the delicate steam position limits the travel of the spray button 22. This arrangement makes it possible on the one hand to limit the opening of the orifice 19 and thereby the quantity of water admitted into the vaporization 2, and on the other hand to prevent the actuation of the second control means 12. Preferably the selector 21 in the dry ironing position blocks the rod 20, directly or by means of the vaporization key 22, to prevent water from entering the vaporization chamber 2.
L'invention concerne également un procédé de régulation pour un fer à repasser électrique à vapeur, comprenant une partie chaude comportant une semelle 1 et une chambre de vaporisation 2, la partie chaude du fer étant divisée en deux zones thermiques, une première zone correspondant sensiblement à la chambre de vaporisation 2 étant dotée de premiers moyens de chauffe 3, une seconde zone correspondant sensiblement à une portion de la semelle 1 disposée sous la chambre de vaporisation 2 étant dotée de seconds moyens de chauffe 4, les premiers moyens de chauffe 3 étant associés à un organe de régulation 5 disposé dans ladite première zone, les premiers moyens de chauffe 3 étant prévus pour assurer partiellement le chauffage de la seconde zone, procédé de régulation dans lequel les premiers moyens de chauffe 3 et les seconds moyens de chauffe 4 sont régulés par l'organe de régulation 5 disposé dans la première zone.The invention also relates to a control method for an electric steam iron, comprising a hot part comprising a soleplate 1 and a vaporization chamber 2, the hot part of the iron being divided into two thermal zones, a first zone corresponding substantially to the vaporization chamber 2 being provided with first heating means 3, a second zone corresponding substantially to a portion of the sole 1 disposed under the vaporization chamber 2 being provided with second heating means 4, the first heating means 3 being associated with a regulating member 5 disposed in said first zone, the first heating means 3 being provided for partially heating the second zone, a regulation method in which the first heating means 3 and the second heating means 4 are regulated by the regulating member 5 disposed in the first zone.
