Description

FER A VAPEUR AVEC JUPE PLASTIQUE ENFERMANT LA CHAMBRE DE VAPORISATION STEAM IRON WITH PLASTIC SKIRT CONTAINING THE VAPORIZATION CHAMBER
La présente invention concerne les fers à repasser à vapeur où l'eau d'un réservoir s'écoule lentement dans une chambre de vaporisation pour y être vaporisée au contact d'une paroi chaude.The present invention relates to steam irons where water from a tank flows slowly into a vaporization chamber to be vaporized there in contact with a hot wall.
On connaît les fers à repasser à vapeur de construction économique, tel que celui décrit dans le brevet FR2770856. De tels fers comportent une semelle ayant un corps chauffant et une chambre de vaporisation, un réservoir comportant une partie supérieure et une partie inférieure. Avantageusement la partie inférieure constitue un écran thermique qui couvre la semelle, et constitue aussi le capot ou jupe du fer.Steam irons of economical construction are known, such as that described in patent FR2770856. Such irons comprise a soleplate having a heating body and a vaporization chamber, a reservoir comprising an upper part and a lower part. Advantageously, the lower part constitutes a heat shield which covers the sole, and also constitutes the cover or skirt of the iron.
La semelle comporte un corps chaud généralement en aluminium moulé et muni d'un élément chauffant. La surface de repassage du fer est à la partie inférieure du corps chaud, laquelle peut être couverte ou non par une plaque présentant de meilleures qualités de repassage. Le corps chaud constitue une chambre de vaporisation, généralement fermée en partie supérieure par une plaque, comme par exemple le brevet FR2581571 en donne une description.The sole has a hot body generally made of cast aluminum and provided with a heating element. The ironing surface of the iron is at the lower part of the hot body, which may or may not be covered by a plate having better ironing qualities. The hot body constitutes a vaporization chamber, generally closed at the top by a plate, as for example the patent FR2581571 gives a description.
Cependant, par le brevet FR2444108 on connaît des fers dont la chambre de vaporisation comporte une face inférieure chauffée essentiellement plane, les parois latérales enfermant la chambre étant obtenues par une pièce de fermeture métallique emboutie, au lieu d'une plaque. Mais les nervures internes à la chambre de vaporisation sont issues du corps chaud moulé, ce qui ne permet pas de simplifier la semelle. Le document FR2372924 illustre une autre construction de la chambre de vaporisation qui est ouverte vers le bas du fer, et fermée par une plaque qui constitue localement la surface de repassage. Les nervures nécessaires à la chambre de vaporisation sont issues d'une paroi horizontale haute du corps chauffant et se prolongent vers le bas du fer jusqu'à la plaque de fermeture. Par ailleurs on connaît le brevet FR2770077 qui décrit une chaudière pour appareil électroménager comportant un corps en matière plastique avec un fond métallique chauffant plat muni d'un élément chauffant. Mais le corps en plastique de cette chaudière n'a pas plusieurs fonctions, ce qui diminue sensiblement l'intérêt de cette réalisation. Les fers connus nécessitent des pièces de fermeture de la chambre de vaporisation et des pièces de liaison entre le réservoir d'eau et cette chambre. De plus la construction ne permet pas la réalisation simple de fers à vapeur dont la semelle est obtenue à partir de tôles métalliques, sans brasage et sans mettre en œuvre des moyens lourds de moulage métalliques. Le but de l'invention est de pallier à ces inconvénients pour réaliser un fer économique.However, from patent FR2444108 irons are known, the vaporization chamber of which has a substantially flat heated underside, the side walls enclosing the chamber being obtained by a stamped metal closure part, instead of a plate. However, the internal ribs in the vaporization chamber come from the molded hot body, which does not make it possible to simplify the sole. Document FR2372924 illustrates another construction of the vaporization chamber which is open towards the bottom of the iron, and closed by a plate which locally constitutes the ironing surface. The ribs necessary for the vaporization chamber come from a high horizontal wall of the heating body and extend downwards from the iron to the closing plate. Furthermore, patent FR2770077 is known which describes a boiler for household appliance comprising a plastic body with a flat metal heating base provided with a heating element. However, the plastic body of this boiler does not have several functions, which significantly reduces the advantage of this embodiment. Known irons require parts for closing the vaporization chamber and connecting parts between the water tank and this chamber. In addition, the construction does not allow the simple production of steam irons, the sole of which is obtained from metal sheets, without brazing and without using heavy metal molding means. The object of the invention is to overcome these drawbacks in order to produce an economical iron.
Le but de l'invention est atteint par un fer à vapeur comportant une semelle chauffante, une chambre de vaporisation, une pièce à fonctions multiples constituant à la fois un écran thermique et la jupe du fer, caractérisé en ce que la pièce à fonctions multiples constitue au moins en partie la chambre de vaporisation au-dessus de la semelle.The object of the invention is achieved by a steam iron comprising a heating soleplate, a vaporization chamber, a multi-function part constituting both a heat shield and the skirt of the iron, characterized in that the multi-function part constitutes at least in part the vaporization chamber above the sole.
Grâce à cette construction originale, le nombre de pièces du fer est réduit et le montage facilité.Thanks to this original construction, the number of pieces of iron is reduced and assembly is facilitated.
De préférence, le fer à vapeur comporte un réservoir d'eau, et la pièce à fonctions multiples constitue le fond du réservoir d'eau.Preferably, the steam iron has a water tank, and the multi-function part constitutes the bottom of the water tank.
Il n'y a pas de joint qui relie une pièce du réservoir à une pièce de la chambre de vaporisation, ni de plaque de fermeture, et la fiabilité est augmentée. Les nervures de la chambre de vaporisation peuvent être issues de la pièce à fonctions multiples et la semelle simplifiée, ce qui permet l'utilisation simple, dans un fer économique, d'éléments chauffants plats.There is no seal that connects a part of the tank to a part of the vaporization chamber, nor a closing plate, and reliability is increased. The ribs of the vaporization chamber can come from the multifunctional part and the simplified soleplate, which allows the simple use, in an economical iron, of flat heating elements.
De préférence la pièce à fonctions multiples est en matière plastique résistante à la chaleur.Preferably the multi-function part is made of heat-resistant plastic.
Cette pièce localement accessible par l'utilisateur peut être chaude. Elle présente une conductivité et une effusivité faibles qui rendent son contact peu dangereux avec la peau. Le moulage du plastique permet des formes complexes qui facilitent les assemblages et les fixations. De préférence la matière plastique de la pièce multifonction est un polyester ou un poly-sulfone.This room, locally accessible to the user, may be hot. It has a low conductivity and effusivity which makes its contact little dangerous with the skin. The plastic molding allows complex shapes which facilitate assemblies and fastenings. Preferably the plastic of the multifunction piece is a polyester or a poly-sulfone.
Dans une version, la jupe du fer constitue les parois de la chambre de vaporisation. La quantité de matière nécessaire à la réalisation est alors minimale. Grâce à a faible effusivité, inférieure à 1000W m"2 °C"1 s1/2 , de la matière plastique, la température de contact avec la peau est faible, et n'est pas dangereuse pour l'utilisateur.In one version, the skirt of the iron constitutes the walls of the vaporization chamber. The amount of material necessary for the realization is then minimal. Thanks to the low effusivity, less than 1000W m "2 ° C " 1 s 1/2 , of the plastic material, the temperature of contact with the skin is low, and is not dangerous for the user.
De préférence la pièce multifonction est en contact avec la semelle par des joints d'étanchéité en mousse d'élastomère.Preferably, the multifunction piece is in contact with the sole by seals made of elastomer foam.
Le joint présente alors une souplesse maximale qui permet une bonne adaptation aux différences de dilatation. La mousse est déposée et adhère sur l'une des pièces à joindre. Elle est polymérisée avant l'assemblage. Des pattes ou des vis maintiennent les pièces serrées entre elles, en comprimant la mousse. Du fait que la mousse ne présente qu'une très faible dureté elle s'adapte bien aux imperfections de surface et de planéité sans nécessiter un serrage trop intensif qui serait incompatible avec la résistance des pièces.The joint then has maximum flexibility which allows good adaptation to differences in expansion. The foam is deposited and adheres to one of the pieces to be joined. It is polymerized before assembly. Legs or screws hold the pieces together, compressing the foam. Because the foam has only very low hardness, it adapts well to surface and flatness imperfections without requiring excessive tightening which would be incompatible with the resistance of the parts.
La mousse peut être obtenue de deux façons. On peut mélanger dans une buse de distribution deux composants qui moussent et polymérisent à la sortie de la buse. De tels produits moussants sont fournis par exemple par la société Wacker. On peut aussi mélanger un produit connu pour ses qualités de joint, tel qu'un silicone, avec un gaz tel que l'azote dans un mélangeur approprié, par exemple un mélangeur de marque Nordson ou Dopag, et le distribuer sur une des pièces à joindre. La polymérisation est plus rapidement obtenue par un chauffage ultérieur.Foam can be obtained in two ways. Two components which foam and polymerize at the outlet of the nozzle can be mixed in a dispensing nozzle. Such foaming products are supplied for example by the company Wacker. It is also possible to mix a product known for its seal qualities, such as a silicone, with a gas such as nitrogen in a suitable mixer, for example a mixer of the Nordson or Dopag brand, and distribute it on one of the parts to join. The polymerization is obtained more quickly by subsequent heating.
Avantageusement, le joint entre les pièces supérieure et inférieure du réservoir est de même nature.Advantageously, the seal between the upper and lower parts of the tank is of the same nature.
L'invention sera mieux comprise au vu des exemples ci-après et des dessins annexés. La figure 1 est une vue en coupe longitudinale par un plan vertical d'un premier fer selon l'invention. La figure 2 est une vue partielle en coupe longitudinale par un plan vertical d'un deuxième fer selon l'invention.The invention will be better understood on the basis of the examples below and the appended drawings. Figure 1 is a longitudinal sectional view through a vertical plane of a first iron according to the invention. Figure 2 is a partial view in longitudinal section through a vertical plane of a second iron according to the invention.
La figure 3 est une vue partielle en coupe longitudinale par un plan vertical d'un troisième fer selon l'invention. La figure 4 est une demi vue de dessus en coupe par un plan horizontal H du fer de la figure 3.Figure 3 is a partial view in longitudinal section through a vertical plane of a third iron according to the invention. FIG. 4 is a half top view in section through a horizontal plane H of the iron of FIG. 3.
La figure 5 est une vue partielle en coupe longitudinale par un plan vertical d'un quatrième fer selon l'invention.Figure 5 is a partial view in longitudinal section through a vertical plane of a fourth shoe according to the invention.
La figure 6 est une demi vue de dessus en coupe par un plan horizontal H du fer de la figure 5.FIG. 6 is a half top view in section through a horizontal plane H of the iron of FIG. 5.
Dans une première version préférentielle de l'invention visible en figure 1 le fer à vapeur 1 comprend une semelle 2, une chambre de vaporisation 3, un réservoir d'eau 4 et un corps 5 incluant une poignée. Un goutte à goutte 6 contrôle le passage de l'eau contenue dans le réservoir 4 vers la chambre de vaporisation 3. Un thermostat électromécanique 7 assure la régulation thermique du fer.In a first preferred version of the invention visible in FIG. 1, the steam iron 1 comprises a soleplate 2, a vaporization chamber 3, a water tank 4 and a body 5 including a handle. A drip 6 controls the passage of the water contained in the reservoir 4 to the vaporization chamber 3. An electromechanical thermostat 7 ensures the thermal regulation of the iron.
La semelle 2 comporte un corps chauffant 21 en aluminium muni d'un élément chauffant lubulaire 211 , et une plaque 22 en aluminium ou en acier inoxydable assemblée mécaniquement et thermiquement sous le corps chauffant 21 , la plaque 22 étant destinée à être en contact avec le linge à repasser. La semelle a une forme essentiellement plane qui comporte, du coté intérieur au fer, seulement les reliefs nécessaires à l'enrobage de l'élément chauffant 211 et à quelques fixations non représentées. La face supérieure 212 du corps chauffant 21 constitue une paroi chaude de la chambre de vaporisation 3, contre laquelle l'eau en provenance du goutte à goutte 6 se vaporise. Cette paroi peut comporter dans la chambre un revêtement anti-caléf action.The soleplate 2 comprises a heating body 21 made of aluminum provided with a lubricating heating element 211, and a plate 22 made of aluminum or stainless steel assembled mechanically and thermally under the heating body 21, the plate 22 being intended to be in contact with the ironing linen. The sole has an essentially flat shape which comprises, on the inner side of the iron, only the reliefs necessary for the coating of the heating element 211 and to some fasteners not shown. The upper face 212 of the heating body 21 constitutes a hot wall of the vaporization chamber 3, against which the water coming from the drip 6 vaporizes. This wall may include in the chamber an anti-caléfaction coating.
Le réservoir 4 d'eau à vaporiser comporte une pièce supérieure 41 et une pièce inférieure à fonctions multiples 8, en polyester résistant à la chaleur et à l'humidité, formant le fond du réservoir 4. Les deux pièces 41 , 8 sont assemblées par un joint 42 en mousse de silicone déposée dans des gorges à la partie supérieure de la pièce 8. La pièce à fonctions multiples 8 constitue en même temps que le fond du réservoir 4, la paroi supérieure de la chambre 3 de vaporisation de l'eau et de répartition de la vapeur vers des trous de sortie 23. Vers le bas de la pièce 8 une nervure périphérique 81 , issue de ladite pièce 8 et s'étendant jusqu'à la semelle, limite latéralement cette chambre de vapeur. D'autres nervures 82, 83 disposées de façon semblable assurent l'isolation du thermostat vis à vis de la vapeur ainsi que les chicanes nécessaires au circuit de vapeur. Des gorges sont prévues en bas des nervures 81, 82, 83 en regard de la semelle 2 et retiennent des joints tels que 84 en mousse de silicone, adhérant à la pièce 8. Des fixations non représentées serrent les pièces 41 , 8, et la semelle 2 l'une contre l'autre en comprimant tous les joints, ce qui assure l'étanchéité entre les pièces.The water spray tank 4 has an upper part 41 and a lower multi-function part 8, made of polyester resistant to heat and humidity, forming the bottom of the tank 4. The two parts 41, 8 are assembled by a seal 42 of silicone foam deposited in grooves at the top of the part 8. The multi-function part 8 constitutes, at the same time as the bottom of the tank 4, the upper wall of the chamber 3 for vaporizing the water and distributing the vapor towards outlet holes 23. Towards the bottom of the part 8 a peripheral rib 81, coming from said part 8 and extending to the sole, laterally limits this vapor chamber. Other ribs 82, 83 arranged in a similar manner ensure the isolation of the thermostat from the steam as well as the baffles necessary for the steam circuit. Grooves are provided at the bottom of the ribs 81, 82, 83 facing the sole 2 and retain seals such as 84 made of silicone foam, adhering to the part 8. Fixings not shown tighten the parts 41, 8, and the sole 2 against each other by compressing all the joints, which ensures sealing between the parts.
La pièce à fonctions multiples 8 constitue aussi la jupe 85 visible entre le corps 5 et la semelle 2 du fer. On voit que cette conception permet une construction très simple du fer, sans conduit entre le réservoir et la chambre de vaporisation, et avec une semelle ne comportant que peu de reliefs intérieurs. La construction est économique, grâce aux fonctions multiples de la pièce 8 qui enferme la chambre de vaporisation. Dans une deuxième version voisine, visible en figure 2 avec les mêmes repères pour les pièces similaires, la semelle 2 comporte un élément chauffant plat 211 semblable à un élément chauffant décrit dans le brevet FR2580887. Le circuit chauffant 211 est entre une plaque inférieure 213 et une plaque supérieure 212 en aluminium. Des goujons non représentés sont soudés sur la plaque supérieure 212 pour permettre le serrage des pièces 8 et 41 contre la semelle. Une coiffe composée d'une plaque 22 en aluminium ou en acier inoxydable est assemblée mécaniquement et thermiquement sous la plaque inférieure 213, la plaque 22 étant destinée à être en contact avec le linge à repasser. La face supérieure de la plaque 212 transfère sa chaleur à l'eau en provenance d'un goutte à goutte 6 et l'évaporé. La vapeur produite est contenue et dirigée vers les trous de vapeur 23 par la pièce 8 semblable à celle de la première version.The multi-function part 8 also constitutes the skirt 85 visible between the body 5 and the sole 2 of the iron. We see that this design allows a very simple construction of the iron, without a conduit between the tank and the vaporization chamber, and with a soleplate having only a few internal reliefs. The construction is economical, thanks to the multiple functions of part 8 which encloses the vaporization chamber. In a second neighboring version, visible in FIG. 2 with the same references for similar parts, the soleplate 2 comprises a flat heating element 211 similar to a heating element described in patent FR2580887. The heating circuit 211 is between a lower plate 213 and an upper plate 212 made of aluminum. Studs not shown are welded to the upper plate 212 to allow the clamping of the parts 8 and 41 against the sole. A cap composed of a plate 22 of aluminum or stainless steel is mechanically and thermally assembled under the lower plate 213, the plate 22 being intended to be in contact with the clothes to be ironed. The upper face of the plate 212 transfers its heat to the water coming from a drip 6 and evaporates it. The steam produced is contained and directed towards the steam holes 23 by the part 8 similar to that of the first version.
Grâce à cette pièce 8 à fonctions multiples l'utilisation d'un élément chauffant plat dans un fer à vapeur est facilitée.Thanks to this multifunctional part 8 the use of a heating element dish in a steam iron is facilitated.
Avantageusement le thermostat peut être un thermostat électronique comme dans la troisième version représentée en figures 3 et 4. La pièce 8 supporte le capteur 71 de thermostat par l'intermédiaire d'un ressort 72 qui le maintien en pression contre la semelle 2, afin d'assurer un bon contact thermique.Advantageously, the thermostat can be an electronic thermostat as in the third version represented in FIGS. 3 and 4. The part 8 supports the thermostat sensor 71 by means of a spring 72 which keeps it in pressure against the soleplate 2, in order to '' ensure good thermal contact.
