The iron has a heating unit (2) with a heater element, this heating unit also having a first vaporizing chamber (210) used for normal ironing, and a second independent vaporizing chamber (220) used for obtaining a surplus of vapor, each of these chambers having a vapor circuit ending in a set of vapor orifices in the sole plate.

Description

La présente invention concerne les fers à repasser à vapeur ayant deux chambres de vaporisation instantanée de l'eau séparées et associées chacune à un circuit de vapeur qui se termine par un jeu d'orifices de distribution de vapeur sous la semelle du fer.The present invention relates to steam irons having two separate water vaporization chambers each associated with a steam circuit which terminates in a set of steam distribution ports under the sole of the iron.

Alors que les premiers fers à vapeur ne disposaient que d'une seule chambre de vaporisation, les constructeurs devaient choisir entre une vaporisation continue avec une évacuation de la vapeur répartie sur la face de repassage, ou une vaporisation brutale sous pression, la sortie de vapeur pouvant être concentrée dans une zone plus faible de la semelle, par exemple à la pointe de la semelle comme le montre par exemple le brevet US2700236.While the first steam irons had only one vaporization chamber, the manufacturers had to choose between a continuous vaporization with an evacuation of steam distributed on the ironing face, or a sudden vaporization under pressure, the steam outlet which can be concentrated in a weaker area of the sole, for example at the tip of the sole as shown for example in the patent US2700236.

Les constructions plus récentes de fers avec deux chambres de vaporisation séparées permettent les deux modes de fonctionnement très différents grâce à la spécialisation de chaque chambre de vaporisation dans un mode déterminé.The more recent constructions of irons with two separate vaporization chambers allow two very different modes of operation thanks to the specialization of each vaporization chamber in a given mode.

Le brevet EP0342302, par exemple, décrit un fer comportant une première et une deuxième chambres de vapeur, dont la deuxième est à proximité de la pointe de la semelle et son jeu d'orifices est concentré à la pointe de la semelle. Le fer fonctionne suivant un mode de repassage conventionnel avec la première chambre et en un mode de surplus de vapeur instantané dit sur-vapeur, en utilisant la deuxième chambre de vapeur, ce dernier mode étant plus particulièrement utile pour défroisser des endroits difficiles du tissu repassé.EP0342302, for example, describes an iron having a first and a second steam chamber, the second is near the tip of the sole and its set of orifices is concentrated at the tip of the sole. The iron operates according to a conventional ironing mode with the first chamber and in a mode of surplus instantaneous steam said over-steam, using the second steam chamber, the latter mode being particularly useful for straightening difficult areas of the fabric ironed .

On connaît aussi le brevet EP0621365 qui décrit un fer similaire comportant deux chambres de vaporisation associées à deux séries d'orifices dans la surface de repassage. Le brevet voisin FR2740787 précise la position de la deuxième chambre et des trous de vapeur associés à l'avant de la semelle.Patent EP0621365 is also known which describes a similar iron having two vaporization chambers associated with two series of orifices in the ironing surface. Neighboring patent FR2740787 specifies the position of the second chamber and steam holes associated with the front of the sole.

Mais la deuxième chambre recevant brutalement une quantité d'eau importante à évaporer est nécessairement concentrée à l'avant de la semelle pour laisser suffisamment de place à la vaporisation normale, ce qui conduit cette deuxième chambre à disposer seulement d'un circuit de vapeur tortueux et passant à proximité des parois d'évaporation de la première chambre ou trop court. Un tel circuit qui s'éloigne de l'élément chauffant réchauffe mal la vapeur, ce qui ne garantit pas une totale évaporation de toutes les gouttelettes d'eau, spécialement quand l'utilisatrice se sert beaucoup d'une des fonctions de vaporisation normale ou de sur-vapeur avant d'utiliser l'autre fonction de vaporisation.But the second chamber suddenly receiving a significant amount of water to be evaporated is necessarily concentrated at the front of the sole to leave sufficient room for normal vaporization, which leads the second chamber to have only a tortuous steam circuit and passing near the evaporation walls of the first chamber or too short. Such circuit that moves away from the heating element does not heat the steam well, which does not guarantee complete evaporation of all the water droplets, especially when the user is using a lot of the normal vaporization functions or Steam before using the other vaporizing function.

L'invention qui suit pallie à ces inconvénients.The following invention overcomes these disadvantages.

Le but de l'invention est atteint par un fer à repasser selon la revendication 1.The object of the invention is achieved by an iron according to claim 1.

Le trajet de la vapeur est ainsi allongé avant sa sortie sur le linge repassé. Les échanges de chaleur entre la vapeur et la semelle ont mieux le temps de s'opérer et l'évaporation de toutes les gouttes d'eau est mieux assurée.The path of the steam is thus lengthened before leaving on the ironed linen. The heat exchanges between the steam and the sole have better time to operate and the evaporation of all the drops of water is better ensured.

De préférence le circuit de vapeur de la deuxième chambre est isolé des parois d'évaporation de la première chambre par une lame d'air.Preferably the vapor circuit of the second chamber is isolated from the evaporation walls of the first chamber by an air gap.

L'usage de la vaporisation continue dans la première chambre ne refroidit pas la deuxième chambre ni ses canaux maintenus chauds pour pouvoir obtenir un surplus de vapeur efficace à tout moment.The use of continuous vaporization in the first chamber does not cool the second chamber or its hot maintained channels to obtain a surplus of effective steam at any time.

De préférence, la deuxième chambre de vaporisation est dans l'axe de la semelle et le circuit de vapeur comporte des deuxièmes canaux supérieur et inférieur, sensiblement symétriques aux premiers.Preferably, the second vaporization chamber is in the axis of the sole and the steam circuit has second upper and lower channels, substantially symmetrical to the first.

On profite ainsi de la symétrie du corps chauffant de la semelle et de son élément chauffant pour augmenter efficacement les échanges thermiques.It thus benefits from the symmetry of the heating body of the sole and its heating element to effectively increase heat exchange.

De préférence les canaux inférieurs se rejoignent dans leur partie terminale vers la pointe de la semelle.Preferably the lower channels meet in their end portion towards the tip of the sole.

On assure ainsi l'équilibre des pressions dans les canaux inférieurs pour obtenir une vaporisation homogène sur le linge.This ensures the equilibrium of the pressures in the lower channels to obtain a uniform vaporization on the laundry.

De préférence les orifices de vapeur associés à la deuxième chambre du corps chauffant débouchent dans la semelle le long des canaux inférieurs et dans leur partie terminale.Preferably the steam ports associated with the second chamber of the heating body open into the sole along the lower channels and in their end portion.

La zone repassée concernée par le surplus de vapeur peut ainsi être étendue par un tracé adapté des canaux inférieurs.The ironed area concerned with the excess steam can thus be extended by a suitable layout of the lower channels.

De préférence la jonction terminale des canaux inférieurs est prolongée par un canal élargi.Preferably the terminal junction of the lower channels is extended by an enlarged channel.

Cette disposition permet de disposer plus de trous de vapeur débouchant dans la partie terminale des canaux inférieurs où la vapeur est la mieux réchauffée.This arrangement makes it possible to have more steam holes opening into the end portion of the lower channels where the steam is better heated.

Dans une version préférée de l'invention, le fer à repasser à vapeur, de forme pointue à l'avant, comporte un ensemble de semelle visible dans les figures 1 et 2 . Ce sous ensemble situé classiquement au dessous du réservoir d'eau du fer à repasser comporte une semelle 1, un corps chauffant 2, une plaque de fermeture 3, et une autre plaque de fermeture 4.In a preferred version of the invention, the steam iron, pointed at the front, has a sole assembly visible in Figures 1 and 2. This subassembly conventionally located below the water reservoir of the iron comprises a soleplate 1, a heating body 2, a closure plate 3, and another closure plate 4.

La semelle 1 est en tôle emboutie pour avoir les bords 100 relevés; la face inférieure 101 sensiblement plane et visible en figure 2, est la face de repassage.The sole 1 is made of sheet metal to have the raised edges 100; the lower face 101 substantially flat and visible in Figure 2, is the ironing face.

Le corps chauffant 2 comprenant un élément chauffant résistif 201 cintré en fer à cheval s'adapte de façon connue sur la face interne 102 de la semelle pour lui être mécaniquement et thermiquement lié. Un bossage 202 au moins est prévu pour recevoir un thermostat de régulation de température.The heating body 2 comprising a resistive heating element 201 curved horseshoe fits in a known manner on the inner face 102 of the sole to be mechanically and thermally bonded thereto. At least one boss 202 is provided to receive a temperature control thermostat.

Le corps chauffant 2 comporte dans sa partie supérieure une première chambre de vaporisation 210 de grandes dimensions et fermée par la plaque de fermeture 3. L'eau du réservoir arrive goutte à goutte dans cette chambre 210 par l'orifice 301 de la plaque 3, se vaporise, et la vapeur distribuée par des canaux 211 traverse le corps 2 pour en sortir sur le tissu repassé par les trous 212 et les trous correspondants 103 de la semelle 1.The heating body 2 comprises in its upper part a first vaporization chamber 210 of large dimensions and closed by the closure plate 3. The water of the reservoir drips into this chamber 210 through the orifice 301 of the plate 3, vaporizes, and the vapor distributed by channels 211 passes through the body 2 to exit on the fabric ironed by the holes 212 and the corresponding holes 103 of the sole 1.

La chambre de vaporisation 210 recevant de l'eau goutte à goutte produit la vapeur pour un repassage normal et classique et son fonctionnement est connu.The vaporization chamber 210 receiving water drop by drop produces steam for normal and conventional ironing and its operation is known.

Le corps chauffant 2 comporte aussi à l'avant de sa partie supérieure une deuxième chambre de vaporisation 220 entourée par le circuit de vapeur précédemment décrit et fermée par la plaque 4. Cette chambre de vapeur limitée par des nervures 221 est située dans l'axe de la semelle au dessus d'un coude de l'élément chauffant 201. Deux canaux chicanés 222 prolongent cette deuxième chambre en longeant, vers l'arrière de la semelle, l'élément chauffant 201 et sont reliés à leur extrémité par un trou traversant verticalement le corps 2 à deux canaux 223 situés sous le corps chauffant. Ces canaux 223 longent l'élément chauffant 201 puis se rejoignent à l'avant du fer où ils se prolongent par un canal 224 élargi.The heating body 2 also comprises, at the front of its upper part, a second vaporization chamber 220 surrounded by the steam circuit previously described and closed by the plate 4. This vapor chamber bounded by ribs 221 is located in the axis from the sole over an elbow of the heating element 201. Two baffled channels 222 extend this second chamber along the back of the sole, the heating element 201 and are connected at their ends by a through hole vertically the body 2 with two channels 223 located under the heating body. These channels 223 run along the heating element 201 and then meet at the front of the iron where they extend through an enlarged channel 224.

Avantageusement, une gorge profonde 225, fermée par la plaque 4, longe les parois de la chambre 210 près desquelles l'eau se vaporise goutte à goutte. Cette gorge 225 immobilise une lame d'air. La chambre 210 se trouve thermiquement isolée par cette lame d'air de la chambre 220 et de son circuit de vapeur 221.Advantageously, a deep groove 225, closed by the plate 4, along the walls of the chamber 210 near which the water vaporizes drop by drop. This groove 225 immobilizes a blade of air. The chamber 210 is thermally insulated by this air gap of the chamber 220 and its steam circuit 221.

Un orifice 302 est ménagé dans la plaque 3 et un orifice 401 est ménagé dans la plaque 4, ces orifices permettant l'introduction d'un tube d'arrivée d'eau dans la chambre de vaporisation 220. De préférence l'eau arrive sous une pression due à l'action de l'opératrice sur une pompe.An orifice 302 is formed in the plate 3 and an orifice 401 is formed in the plate 4, these orifices allowing the introduction of a water inlet tube into the vaporization chamber 220. Preferably the water arrives under a pressure due to the action of the operator on a pump.

Dans la semelle 1 des trous de sortie de vapeur 104 sont en correspondance avec les canaux 223 et 224. Le circuit de vapeur associé à la deuxième chambre 220 est ainsi totalement indépendant du circuit de vapeur associé à la première chambre 210 de vaporisation.In the sole 1 of the steam outlet holes 104 are in correspondence with the channels 223 and 224. The steam circuit associated with the second chamber 220 is thus totally independent of the steam circuit associated with the first vaporization chamber 210.

Lorsque l'opératrice désire un surplus de vapeur elle commande la pompe associée à la deuxième chambre de vapeur 220. L'eau arrive brutalement dans cette chambre et se vaporise grâce à la chaleur accumulée dans la masse du fer et grâce à l'élément chauffant 201 situé immédiatement au dessous de la chambre 220. Même si le fer a précédemment été utilisé longtemps en vapeur normale, la chambre 220 et ses canaux de vapeur sont chauds car ils sont isolés de la chambre 210 par la gorge 225. La vapeur s'échappe dans les canaux chicanés 222 situés au dessus de l'élément chauffant dans une partie massive du corps 2, en entraînant des gouttes avec elle. Mais grâce au développement en longueur des canaux, et à leur protection thermique par la gorge 225, ces gouttes s'y vaporisent complètement. La vapeur atteint ensuite les canaux inférieurs 223 et les gouttes qui n'auraient pas pu le faire suffisamment, notamment par suite d'un usage trop intensif de la sur-vapeur, continuent à échanger de la chaleur avec le corps chauffant 2. Cet échange est d'autant plus intense que les canaux sont tracés de façon à suivre le trajet de l'élément chauffant 201 dans le corps 2. Le trajet de la vapeur étant allongé par ces moyens, la vapeur sort par les trous 104 de la semelle 1 sans aucune chance d'entraîner des gouttes d'eau sur le tissu repassé.When the operator desires a surplus of steam she controls the pump associated with the second steam chamber 220. The water suddenly arrives in this chamber and vaporizes thanks to the heat accumulated in the mass of the iron and thanks to the heating element 201 located immediately below the chamber 220. Although the iron has previously been used for a long time in normal steam, the chamber 220 and its steam channels are hot because they are isolated from the chamber 210 by the throat 225. The steam is escapes into the baffled channels 222 located above the heating element in a solid part of the body 2, causing drops with it. But thanks to the development in length of the channels, and their thermal protection by the throat 225, these drops are vaporized completely. The steam then reaches the lower channels 223 and the drops which could not have done so sufficiently, in particular as a result of too intensive use of the steam, continue to exchange heat with the heating body 2. This exchange is all the more intense as the channels are traced so as to follow the path of the heating element 201 in the body 2. The path of the vapor being elongated by these means, the vapor exits through the holes 104 of the sole 1 without any chance of causing drops of water on the ironed fabric.

Avantageusement les canaux inférieurs 223 se rejoignent à leur extrémité où la vapeur est sèche, ce qui équilibre les pressions de vapeur et homogénéise l'action sur le linge. Les canaux réunis peuvent sans inconvénient se prolonger par un canal unique susceptible de concerner des trous de vapeur 104 situés dans des endroits où deux canaux ne se justifieraient pas et n'auraient pas leur place tel qu'à l'avant du fer.Advantageously, the lower channels 223 meet at their end where the steam is dry, which balances the vapor pressures and homogenizes the action on the laundry. The combined channels may conveniently be extended by a single channel capable of involving steam holes 104 located in places where two channels would not be justified and would not have their place as at the front of the iron.

Par ces moyens on obtient un surplus de vapeur efficace, permettant un usage intensif de ce mode de repassage sans risquer des gouttes et des coulures sur le linge.By these means we obtain a surplus of effective steam, allowing intensive use of this ironing mode without risking drops and drips on the laundry.
