C., the bimetallic strip 16 is bent downwards and is not in contact with the end pad 11A of the axis of the regulation valve 10. , the weight of the axis 11 and the elasticity of the membrane 90 ensuring the closing of the valve 12. Under these conditions, the water of the reservoir 7 can not flow to the intermediate chamber 15 so that the chamber of vaporization 53 does not receive water, even if the plug 8 is in the open position, as illustrated, for example, in FIG. figure 7 , for a steam ironing.
- the bimetal 16 thus provides an anti-drip function by preventing the water from being sent into the vaporization chamber 53 when the temperature of the latter is not sufficient to ensure its evaporation.
- the bimetallic strip 16 comes into contact with the end pad 11A of the axis of the regulation valve 10 and then exerts on the latter a vertical pressure. who tends to lift the axis 11 and the valve 12 associated therewith. Beyond this temperature, the pressure exerted by the bimetallic strip 16 raises the valve 12 and the water of the tank 7 can flow at a low flow rate through the orifice 13 towards the intermediate chamber 15.
- the bimetallic When the temperature of the sole reaches an intermediate temperature, around 140 ° C., the bimetallic contacts the spring rod 18, as illustrated on FIG. figure 7 which represents an enlarged view of the feed circuit.

- the rod 80 of the plug In this position of the button 4, the rod 80 of the plug is moved downwards and the second notch 80B, of larger section, is opposite the nozzle seal 9 thus allowing the sudden arrival of a large amount of This self-cleaning operation, known per se, is carried out with the temperature thermostat of the soleplate 1 set to the maximum temperature.
- the movement of the rod 80 downward is accompanied by a push of the lug 81 on the end of the lever 14 which causes the tilting of the latter, the opposite end of the lever holding the axis 11 of the control valve 10 in a raised position, corresponding to the maximum degree of opening of the valve 10.

- a regulating device thus makes it possible to considerably reduce the impact of the mounting tolerances of the heat shield on the heating body on the regulation of the regulating device.
- the spring rod being fixed directly on the heat shield, this reduces the inaccuracies due to mounting dispersions since the control valve and the spring rod are carried by the same piece.
- bimetallic strip with the temperature below the reference temperature makes it possible to maintain a very reactive system in low temperatures so that the system effectively performs the anti-drip function, by ensuring the rapid blocking of the flow of water towards the vaporization chamber, when the latter is not at a temperature sufficient to ensure the evaporation of drops of water.
- the shape of the bimetallic strip may, for example, be in the form of a disk or a thermostatic spring.

Description
La présente invention concerne les fers à repasser comprenant une semelle, surmontée d'un corps chauffant muni d'une chambre de vaporisation et se rapporte plus particulièrement à un fer à repasser dans lequel la chambre de vaporisation communique avec un réservoir au moyen d'un circuit d'alimentation comportant une vanne de régulation dont l'ouverture est commandée par un élément thermiquement déformable en relation thermique avec le corps chauffant.The present invention relates to irons comprising a soleplate, surmounted by a heating body provided with a vaporization chamber and relates more particularly to an iron in which the vaporization chamber communicates with a reservoir by means of a supply circuit comprising a control valve whose opening is controlled by a thermally deformable element in thermal relation with the heating body.

Il est connu du brevet
Cependant, de tels fers présentent l'inconvénient d'avoir un dispositif de régulation automatique du débit de vapeur qui est très sensible au positionnement relatif du bilame par rapport à la vanne de régulation de sorte que le réglage de la vapeur obtenu pour une température donnée est variable d'un fer à l'autre et dépend notamment des tolérances de fabrication et d'assemblage des pièces. En particulier, la plage de déformation d'un bilame pour les températures de fonctionnement d'un fer est limitée, de l'ordre de 3 mm, de sorte que le réglage du débit de vapeur est très sensible à un écart de positionnement du bilame. De tels fers à repasser ne permettent donc pas d'obtenir un réglage optimisé du débit de vapeur pour une température donnée de la semelle, au détriment de l'efficacité de repassage.However, such irons have the disadvantage of having a device for automatic regulation of the steam flow rate which is very sensitive to the relative positioning of the bimetallic strip with respect to the control valve so that the adjustment of the steam obtained for a given temperature is variable from one iron to another and depends in particular on manufacturing tolerances and assembly of parts. In particular, the deformation range of a bimetallic strip for the operating temperatures of an iron is limited, of the order of 3 mm, so that the control of the steam flow rate is very sensitive to a positioning difference of the bimetal. . Such irons therefore do not allow to obtain an optimized setting of the steam flow for a given temperature of the sole, to the detriment of the ironing efficiency.
Ainsi, le but de la présente invention est de remédier à ces inconvénients en proposant un fer à repasser comportant un dispositif de réglage automatique du débit de vapeur qui soit moins sensible aux tolérances de fabrication et d'assemblage des pièces de manière à assurer, d'un fer à l'autre, un réglage plus constant du débit de vapeur pour une température donnée de la semelle.Thus, the object of the present invention is to overcome these disadvantages by providing an iron having an automatic steam flow control device which is less sensitive to manufacturing and assembly tolerances of the parts so as to ensure, from one iron to the other, a more constant adjustment of the flow rate of steam for a given temperature of the sole.
Un autre but de la présente invention est de proposer un fer comportant un dispositif de régulation automatique du débit de vapeur possédant une très bonne réactivité dans les basses températures afin d'éviter que de l'eau ne soit admise dans la chambre de vaporisation lorsque celle-ci est trop froide pour vaporiser l'eau et risque de goutter à travers les trous de sortie de vapeur de la semelle.Another object of the present invention is to provide an iron comprising a device for automatic regulation of the steam flow having a very good reactivity in low temperatures in order to prevent water from being admitted into the vaporization chamber when the It is too cold to spray water and may drip through the steam outlet holes in the soleplate.
Le but de l'invention est atteint par un fer à repasser à vapeur comprenant une semelle en relation thermique avec un corps chauffant muni d'une chambre de vaporisation, la chambre de vaporisation communiquant avec un réservoir au moyen d'un circuit d'alimentation comportant une vanne de régulation du débit dont le degré d'ouverture est commandé par un élément thermiquement déformable en relation thermique avec le corps chauffant, caractérisé en ce que l'ouverture de la vanne de régulation est freinée, à partir d'une température intermédiaire, par un élément stabilisateur exerçant un effort s'opposant à l'effort généré par l'élément thermiquement déformable.The object of the invention is achieved by a steam iron comprising a soleplate in thermal relation with a heating body provided with a vaporization chamber, the vaporization chamber communicating with a reservoir by means of a feed circuit comprising a flow control valve whose degree of opening is controlled by a thermally deformable element in thermal relation with the heating body, characterized in that the opening of the control valve is braked from an intermediate temperature by a stabilizing element exerting a force opposing the force generated by the thermally deformable element.
Une telle caractéristique présente l'avantage de permettre l'établissement d'un palier dans la loi d'ouverture de la vanne de régulation en fonction de la température. Le degré d'ouverture de la vanne est ainsi stabilisé, sur une plage de température de plusieurs degrés à partir de la température intermédiaire, à une valeur permettant un débit de vapeur adapté à la température intermédiaire de la semelle. De plus, le fait que l'élément stabilisateur n'agisse pas sur l'ouverture de la vanne en deçà de la température intermédiaire permet de conserver une grande réactivité de la vanne pour les basses températures de fonctionnement du fer, ce qui permet d'assurer une fonction anti-goutte efficace.Such a feature has the advantage of allowing the establishment of a bearing in the opening law of the control valve as a function of temperature. The degree of opening of the valve is thus stabilized, over a temperature range of several degrees from the intermediate temperature, to a value allowing a flow of steam adapted to the intermediate temperature of the sole. In addition, the fact that the stabilizing element does not act on the opening of the valve below the intermediate temperature makes it possible to maintain a high reactivity of the valve for the low operating temperatures of the iron, which makes it possible to ensure an effective anti-gout function.
Selon l'invention, la température intermédiaire à partir de laquelle l'élément thermiquement déformable commence à être freiné par l'élément stabilisateur est comprise entre 130°C et 150°C.According to the invention, the intermediate temperature from which the thermally deformable element begins to be braked by the stabilizing element is between 130 ° C and 150 ° C.
Selon une autre caractéristique de l'invention, l'élément stabilisateur est constitué par une tige ressort.According to another characteristic of the invention, the stabilizing element is constituted by a spring rod.
Selon une autre caractéristique de l'invention, l'effort produit par l'élément stabilisateur s'exerce directement sur un organe de la vanne de régulation.According to another characteristic of the invention, the force produced by the stabilizing element is exerted directly on a member of the control valve.
Selon une autre caractéristique de l'invention, l'effort produit par l'élément stabilisateur s'exerce directement sur l'élément thermiquement déformable.According to another characteristic of the invention, the force produced by the stabilizing element is exerted directly on the thermally deformable element.
Selon encore une autre caractéristique de l'invention, l'élément stabilisateur et la vanne de régulation sont portés par une même pièce support.According to yet another characteristic of the invention, the stabilizing element and the regulating valve are carried by the same support piece.
Selon autre caractéristique de l'invention, la pièce support est un écran thermique disposé au-dessus du corps chauffant.According to another characteristic of the invention, the support piece is a heat shield disposed above the heating body.
Selon autre caractéristique de l'invention, l'élément thermiquement déformable est un bilame.According to another characteristic of the invention, the thermally deformable element is a bimetallic strip.
Selon encore une autre caractéristique de l'invention, le circuit d'alimentation comporte également un boisseau disposé en série avec la vanne de régulation, le boisseau pouvant occuper une position fermée pour effectuer un repassage à sec et au moins une position ouverte calibrée pour laisser passer un débit d'eau correspondant au taux de vapeur maximum que peut fournir la chambre de vaporisation.According to yet another characteristic of the invention, the supply circuit also comprises a plug arranged in series with the regulating valve, the plug being able to occupy a closed position for carrying out dry ironing and at least one open position calibrated to allow pass a flow of water corresponding to the maximum vapor rate that can provide the vaporization chamber.
Selon une autre caractéristique de l'invention, le boisseau peut occuper une position supplémentaire permettant de laisser passer brutalement une plus grande quantité d'eau pour effectuer une opération d'autonettoyage.According to another characteristic of the invention, the plug can occupy an additional position to allow a larger amount of water to pass abruptly to perform a self-cleaning operation.

Le boîtier 2 renferme un réservoir d'eau 7 dont la partie inférieure est définie par l'écran thermique 6, ce dernier comportant un canal annulaire 62 recevant, avec interposition d'un cordon d'étanchéité, les parois du boîtier 2 définissant la partie supérieure du réservoir.The
Conformément aux
La tige 80 du boisseau peut être amenée, par le bouton de commande 4, dans trois positions distinctes permettant respectivement un repassage à sec, un repassage à la vapeur et une opération d'autonettoyage du fer pour son détartrage.The
A cet effet, la tige 80 comporte une partie pleine, venant fermer l'orifice du joint d'ajutage 9 lorsque la tige 80 est amenée dans la position illustrée à la
La tige 80 comporte également une première encoche 80A possédant une section de passage limitant le débit d'eau maximum envoyé vers la chambre de vaporisation 53 lorsque la tige 80 du boisseau est amenée dans la position illustrée aux
Enfin, la tige 80 du boisseau comporte une deuxième encoche 80B offrant une plus grande section de passage et permettant le nettoyage du fer, par l'apport brutal d'une grande quantité d'eau dans la chambre de vaporisation 53 surchauffée, lorsque la tige 80 est amenée dans la position illustrée à la
Le circuit d'alimentation comporte, en amont du boisseau 8, une vanne de régulation 10 et une chambre intermédiaire 15 disposée entre la vanne de régulation 10 et le boisseau 8.The supply circuit comprises, upstream of the
La vanne de régulation 10 comporte un axe 11 muni d'une partie conique 11B s'étendant à l'intérieur d'un orifice 13 débouchant dans le fond du réservoir 7 de sorte que la section de passage de l'eau du réservoir vers la chambre intermédiaire varie lorsque l'axe 11 se déplace axialement dans l'orifice 13. La partie supérieure de l'axe 11 supporte un clapet 12, constitué par une cloche en caoutchouc enserrant l'axe 11, la périphérie du clapet 12 venant en contact étanche avec le pourtour de l'orifice 13 lorsque l'axe 11 est déplacé axialement vers le bas, ainsi que cela est représenté sur la
L'extrémité supérieure de l'axe 11 est reliée à une extrémité d'un levier 14 monté basculant sur une paroi 63 portée par l'écran thermique 6, l'autre extrémité du levier 14 présentant une ouverture traversée par la tige 80 du boisseau, ce dernier comportant un ergot 81 venant appuyer sur l'extrémité du levier 14 lorsque le bouton de commande 4 est amené dans la position d'autonettoyage.The upper end of the
La partie inférieure de l'axe 11 traverse une membrane d'étanchéité 90 et présente une extrémité arrondie formant un plot 11A venant en regard de l'extrémité libre d'un bilame 16 de forme allongé porté par le corps chauffant 5, le bilame 16 étant fixé sur un bossage 55 du corps chauffant 5 au moyen d'une vis 17. De manière avantageuse, la membrane d'étanchéité 90 est portée par la pièce en caoutchouc rapportée sur l'écran thermique 6 définissant également le joint d'ajutage 9, cette pièce en caoutchouc délimitant la partie inférieure de la chambre intermédiaire 15.The lower part of the
Plus particulièrement selon l'invention, la vanne de régulation 10 comporte un élément stabilisateur constitué par une tige ressort 18 portée par l'écran thermique 6. Cette tige ressort 18 est avantageusement fixée à l'une de ses extrémités sur la face inférieure de l'écran thermique 6 au moyen d'une vis 19, l'autre extrémité de la tige ressort 18 s'étendant librement au-dessus du bilame 16 et venant en bordure du plot 11A de la vanne de régulation, ainsi que l'on peut bien le voir sur la
Le fonctionnement du dispositif de régulation va maintenant être décrit en relation avec les
La
Conformément à cette figure, lorsque la température de la semelle est inférieure à 120°C, le bilame 16 est courbé vers le bas et n'est pas en contact avec le plot d'extrémité 11A de l'axe de la vanne de régulation 10, le poids de l'axe 11 et l'élasticité de la membrane 90 assurant la fermeture du clapet 12. Dans ces conditions, l'eau du réservoir 7 ne peut pas s'écouler vers la chambre intermédiaire 15 de sorte que la chambre de vaporisation 53 ne reçoit pas d'eau, même si le boisseau 8 se trouve en position ouverte, telle qu'illustrée par exemple à la
Le bilame 16 assure ainsi une fonction anti-goutte en empêchant que l'eau ne soit envoyée dans la chambre de vaporisation 53 lorsque la température de cette dernière n'est pas suffisante pour assurer son évaporation.The bimetal 16 thus provides an anti-drip function by preventing the water from being sent into the
Lorsque la température de la semelle 1 atteint une température de l'ordre de 120°C, le bilame 16 rentre en contact avec le plot d'extrémité 11A de l'axe de la vanne de régulation 10 puis exerce sur ce dernier une pression verticale qui tend à soulever l'axe 11 et le clapet 12 qui lui est associé. Au-delà de cette température, la pression exercée par le bilame 16 soulève le clapet 12 et l'eau du réservoir 7 peut s'écouler à faible débit au travers de l'orifice 13 vers la chambre intermédiaire 15.When the temperature of the
Lorsque la température de la semelle atteint une température intermédiaire, autour de 140°C, le bilame arrive au contact de la tige ressort 18, tel que cela est illustré sur la
A partir de cette température intermédiaire, la déformation du bilame 16 est freinée par les efforts générés par la tige ressort 18 de sorte qu'un soulèvement supplémentaire de l'axe 11 n'intervient que si la force générée par le bilame 16 est supérieure à la force générée par la tige ressort 18. Ce soulèvement supplémentaire intervient avantageusement à partir de 160°C et le déplacement de l'axe 11 de la vanne de régulation 10, freiné par la tige ressort 18, est ensuite sensiblement linéaire avec l'augmentation de la température jusqu'à atteindre l'ouverture de la vanne 10 maximum, illustrée à la
On obtient ainsi entre cette température, de l'ordre de 160°C, pour laquelle l'effort généré par le bilame 16 est supérieur à l'effort généré par la tige ressort 18, et la température de repassage maximale de la semelle, un déplacement contrôlé de l'axe 11 de la vanne de régulation 10 et donc une augmentation progressive du débit d'eau s'écoulant vers la chambre de vaporisation 53, ce dernier étant défini par la section de passage au niveau de la partie conique 11B de l'axe traversant l'orifice 13.Thus, between this temperature, of the order of 160 ° C, for which the force generated by the
De manière avantageuse, le débit d'eau pouvant être envoyé vers la chambre de vaporisation 53 est limité à une valeur maximale définie par la section de passage de la première encoche 80A de la tige du boisseau, cette première encoche 80A étant dimensionnée pour correspondre au débit de vapeur maximal pouvant être produit par la chambre de vaporisation 53, compte tenu de la puissance de l'élément chauffant 51. A titre d'exemple, la première gorge 80A sera dimensionnée pour autoriser un débit d'eau maximum correspondant à une production de l'ordre de 35 g/mn de vapeur d'eau.Advantageously, the flow of water that can be sent to the

Conformément à ces figures, le circuit d'alimentation comporte une vanne de régulation 110 comprenant un axe 111 sensiblement cylindrique s'étendant à l'intérieur de l'orifice 13 du fond du réservoir, cet axe 111 supportant un clapet 112, constitué par une cloche en caoutchouc, susceptible d'obturer l'orifice 13 lorsque l'axe 111 est déplacé vers le bas.According to these figures, the supply circuit comprises a regulating
Plus particulièrement selon l'invention, la vanne de régulation 110 comporte un élément stabilisateur constitué par une tige ressort 118 portée par l'écran thermique 6. Cette tige ressort 118 présente l'une de ses extrémités fixée sur la face supérieure de l'écran thermique 6 au moyen d'une vis 119, l'autre extrémité de la tige ressort 118 présentant une boucle s'étendant au dessus du clapet 112 en venant exercer sur ce dernier une pression vers le bas pour fermer le clapet 112 et empêcher l'écoulement de l'eau du réservoir 7 vers l'orifice 13.More particularly according to the invention, the
De manière semblable au premier mode de réalisation, l'extrémité supérieure de l'axe 111 est reliée au levier 14 monté basculant sur la paroi 63 et la partie inférieure de l'axe 111 présente une extrémité arrondie formant un plot 111A traversant la membrane d'étanchéité 90 et venant en regard de l'extrémité libre du bilame 16 porté par le corps chauffant 5.In a manner similar to the first embodiment, the upper end of the
Plus particulièrement selon cette variante de réalisation, l'axe 111 de la vanne 110 présente quatre ailettes 113 s'étendant à 90° l'une de l'autre entre le clapet 112 et la membrane 90, ces ailettes formant des entretoises participant notamment à l'immobilisation de la membrane 90 sur l'axe 111.More particularly according to this variant embodiment, the
Comme on peut mieux le voir sur les
La hauteur de la rainure 111B est supérieure à la hauteur de la lèvre 112B de manière à ce que l'axe 111 puisse se déplacer axialement de quelques millimètres au travers du clapet 112 entre une position de fermeture, illustrée à la
Le fonctionnement du dispositif de régulation selon le second mode de réalisation va maintenant être décrit en relation avec les
La
Lorsque la température de la semelle 1 augmente, le bilame 16 entre en contact avec le plot 111A de l'axe de la vanne de régulation et soulève légèrement ce dernier pour amener le bord inférieur de la rainure 111B au contact du bord inférieur de la lèvre 112B, ainsi que cela est illustré aux
Conformément à la
Lorsque la température de la semelle atteint les seuils de température de l'ordre de 160°C, la force exercée par le bilame 16 sur le plot 111A de l'axe est supérieure à la force exercée par la tige ressort 118 sur le clapet 112, de sorte que le clapet 112 est soulevé du fond du réservoir 7, ainsi que cela est illustré
On obtient ainsi un fer à vapeur muni d'un dispositif de régulation automatique de la vapeur en fonction de la température de la semelle dans lequel l'ouverture de la vanne de régulation du débit d'eau envoyée vers la chambre de vaporisation est, autour d'une température intermédiaire, stabilisée à une valeur prédéterminée par la tige ressort de sorte que l'ouverture de la vanne est sensiblement constante sur une plage de température d'une dizaine de degrés au-delà de cette température intermédiaire. Un tel dispositif de régulation permet ainsi de réduire considérablement l'impact des tolérances de montage de l'écran thermique sur le corps chauffant sur le réglage du dispositif de régulation. De plus, la tige ressort étant fixée directement sur l'écran thermique, ceci permet de réduire les imprécisions dues aux dispersions de montage étant donné que la vanne de régulation et la tige ressort sont portées par une même pièce.This gives a steam iron equipped with a device for automatic regulation of the steam as a function of the temperature of the soleplate in which the opening of the water flow control valve sent to the vaporization chamber is around an intermediate temperature, stabilized at a predetermined value by the rod spring so that the opening of the valve is substantially constant over a temperature range of about ten degrees beyond this intermediate temperature. Such a regulating device thus makes it possible to considerably reduce the impact of the mounting tolerances of the heat shield on the heating body on the regulation of the regulating device. In addition, the spring rod being fixed directly on the heat shield, this reduces the inaccuracies due to mounting dispersions since the control valve and the spring rod are carried by the same piece.
A l'inverse, la libre déformation du bilame avec la température en deçà de la température de référence permet de conserver un système très réactif dans les basses températures de sorte que le système assure efficacement la fonction anti-goutte, en assurant le blocage rapide du débit d'eau vers la chambre de vaporisation, lorsque cette dernière n'est pas à une température suffisante pour assurer l'évaporation des gouttes d'eau.Conversely, the free deformation of bimetallic strip with the temperature below the reference temperature makes it possible to maintain a very reactive system in low temperatures so that the system effectively performs the anti-drip function, by ensuring the rapid blocking of the flow of water towards the vaporization chamber, when the latter is not at a temperature sufficient to ensure the evaporation of drops of water.
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 non représentée la forme du bilame pourra par exemple présenter la forme d'un disque ou d'un ressort thermostatique.Thus, in an embodiment variant not shown, the shape of the bimetallic strip may, for example, be in the form of a disk or a thermostatic spring.
Ainsi, dans une autre variante de réalisation non représentée la vanne de régulation pourra être une vanne rotative.Thus, in another variant embodiment not shown the control valve may be a rotary valve.
