Description

FER A REPASSER A VAPEUR STEAM IRON
La présente invention se rapporte aux fers à repas¬ ser qui comportent une semelle s'étendant longitudinale- ment d'une pointe vers un talon et comprenant une base chauffante et une plaque de repassage montée sous ladite base.The present invention relates to meal irons ser that have a sole extending longitudinally from a point to a heel and comprising a heating base and an ironing plate mounted under said base.
Elle concerne, plus particulièrement, les fers à repasser qui comportent deux chambres de vaporisation in¬ dépendantes pratiquées dans la base et fermées par un couvercle, soit une première chambre de vaporisation principale alimentée en eau au moyen d'un premier dispo¬ sitif d'injection au travers d'une première ouverture 5 pratiquée dans le couvercle et communiquant, par l'inter¬ médiaire d'orifices de distribution de vapeur débouchant sur la face inférieure de la base, avec des premiers trous de sortie de vapeur percés dans la plaque et en re¬ lation avec lesdits orifices de distribution de vapeur, ( soit une deuxième chambre de vaporisation disposée en avant de ladite première chambre, alimentée en eau au moyen d'un deuxième dispositif d'injection au travers d'une deuxième ouverture pratiquée dans le couvercle et communiquant, par l'intermédiaire d'au moins un passage 5 traversant débouchant sur la face inférieure de la base, avec une chambre de distribution de vapeur ménagée dans la face inférieure de ladite base et en relation avec des deuxièmes trous de sortie de vapeur percés dans la pla¬ que. dIt relates, more particularly, to irons which have two independent vaporization chambers made in the base and closed by a cover, ie a first main vaporization chamber supplied with water by means of a first device of injection through a first opening 5 made in the cover and communicating, by means of steam distribution orifices opening onto the underside of the base, with first steam outlet holes drilled in the plate and in relation to said vapor distribution orifices, (a second vaporization chamber disposed in front of said first chamber, supplied with water by means of a second injection device through a second opening made in the cover and communicating, via at least one through passage 5 opening out on the underside of the base, with a distribution chamber steam ion formed in the underside of said base and in connection with second steam outlet holes drilled in the plate. d
On sait que de tels fers à deux chambres de vapori¬ sation indépendantes dont la première dite principale est une chambre pour la production de jets continus de vapeur à faible pression et dont la deuxième est une chambre 5 pour la production de jets de vapeur à pression élevée et forte pénétration, sont particulièrement efficaces pour répondre aux diverses caractéristiques des tissus à repasser.It is known that such irons have two independent vaporization chambers, the first of which, called the main one, is a chamber for the production of continuous jets of steam at low pressure and the second of which is a chamber 5 for the production of steam jets at pressure. high and high penetration, are particularly effective for meet the various characteristics of the fabrics to be ironed.
Dans des fers à repasser à vapeur connus de ce genre, la chambre de distribution de vapeur ménagée dans la face inférieure de la base chauffante, et de manière concomitante, les trous correspondants de sortie de jets de vapeur à pression élevée et forte pénétration, sont généralement disposés à peu près dans la partie médiane de la semelle. Une telle disposition de ces trous de sortie de vapeur donne entière satisfaction sur le plan de la qualité du repassage, mais néanmoins, est relativement mal adaptée sur le plan du confort de repassage de l'utilisateur lorsque celui-ci doit effectuer avec soin le marquage des plis dans les tissus épais, par exemple des plis de chemises.In known steam irons of this kind, the steam distribution chamber formed in the underside of the heating base, and concomitantly, the corresponding holes for the outlet of steam jets at high pressure and high penetration, are generally arranged approximately in the middle part of the sole. Such an arrangement of these steam outlet holes is entirely satisfactory in terms of the quality of ironing, but nevertheless is relatively ill-suited in terms of the ironing comfort of the user when the latter has to carry out the marking with care. folds in thick fabrics, for example shirt folds.
L'invention a notamment pour but de remédier à cet inconvénient et de réaliser d'une manière simple un fer à repasser à vapeur, du type exposé ci-dessus, dont la se¬ melle offre à l'utilisateur les meilleures conditions de repassage tout en assurant une bonne qualité du repassage quelles que soient les caractéristiques des tissus à re¬ passer.The object of the invention is in particular to remedy this drawback and to produce in a simple manner a steam iron, of the type described above, the sole of which provides the user with the best ironing conditions possible. ensuring good quality ironing regardless of the characteristics of the fabrics to be passed.
Selon l'invention, la chambre de distribution de vapeur s'étend dans une région située dans la pointe de la base chauffante de la semelle, et les deuxièmes trous de sortie de vapeur en relation avec ladite chambre de distribution de vapeur sont groupés dans la pointe de la plaque de la semelle.According to the invention, the steam distribution chamber extends in a region situated in the tip of the heating base of the sole, and the second steam outlet holes in relation to said steam distribution chamber are grouped in the tip of the soleplate.
Ainsi, grâce à cette disposition particulière des trous de sortie de jets de vapeur à pression élevée et forte pénétration, la diffusion de vapeur est concentrée à la pointe même de la semelle, et de fait le confort de repassage de l'utilisateur, en particulier pour le mar¬ quage, des plis des tissus, est notablement amélioré puisqu'il suffit à l'utilisateur de "suivre" la pointe de la semelle, que l'on peut qualifier de pointe dynamique 5 de guidage, pour diriger correctement le fer le long du pli à marquer, lui permettant ainsi d'exécuter avec soin et grande facilité cette opération de marquage des plis des tissus.Thus, thanks to this particular arrangement of the outlet holes for steam jets at high pressure and high penetration, the vapor diffusion is concentrated at the very tip of the soleplate, and therefore the comfort of ironing of the user, in particular for marking the folds of the fabrics, is notably improved since it suffices for the user to "follow" the tip of the sole, which can be described as a dynamic tip 5 guide, to correctly direct the iron along the fold to be marked, thus allowing it to execute with care and great ease this operation of marking the folds of the fabrics.
lo Dans une forme de réalisation préférée, les deuxiè¬ mes trous de sortie de vapeur définissent ensemble une plage de vaporisation de forme approximativement triangu¬ laire dont le sommet est situé à proximité immédiate du sommet de la pointe de la plaque de la semelle.lo In a preferred embodiment, the second steam outlet holes together define a spray range of approximately triangular shape, the apex of which is located in close proximity to the apex of the tip of the sole plate.

~ "i Dans l'exemple de réalisation illustré aux figures ~ " i In the embodiment illustrated in the figures
I à 4 , un fer à repasser électrique à vapeur comporte une semelle, désignée par le repère général 10 à la figure 1, qui s'étend longitudinalement d'une région formant pointeI to 4, an electric steam iron has a soleplate, designated by the general reference 10 in FIG. 1, which extends longitudinally from a region forming a point
II vers une région formant talon 13 et qui comprend une 35 base ou corps 15 réalisé en un matériau métallique moulé tel que, par exemple, l'aluminium, fermé de manière étanche par un couvercle 17 en tôle et chauffé au moyen d'une résistance électrique blindée 18 noyée dans sa masse et ayant une forme en U, ainsi qu'une mince plaque de repassage 21 réalisée en un matériau métallique tel que, par exemple, l'acier chromé ou l'acier inoxydable, montée sur la face inférieure 23 de la base chauffante 15 par tout moyen de fixation approprié et dont la face externe 25 forme une surface de repassage. La base chauffante 15 (figures 2 et 3) et la plaque de repassage 21 (figure 4) de la semelle ont le même axe de symétrie longitudinal, noté XX'.II towards a heel region 13 and which comprises a base or body 15 made of a molded metallic material such as, for example, aluminum, closed in a manner sealed by a cover 17 made of sheet metal and heated by means of an armored electrical resistance 18 embedded in its mass and having a U shape, as well as a thin ironing plate 21 made of a metallic material such as, for example, the chromed steel or stainless steel, mounted on the underside 23 of the heating base 15 by any suitable fixing means and the outer face 25 of which forms an ironing surface. The heating base 15 (Figures 2 and 3) and the ironing plate 21 (Figure 4) of the sole have the same longitudinal axis of symmetry, denoted XX '.
Comme le montrent les figures 1 et 2, dans la base chauffante 15 de la semelle 10 sont pratiquées deux cham- bres de vaporisation indépendantes 28,29 séparées par une cloison verticale 31 et fermées par le couvercle 17.As shown in FIGS. 1 and 2, in the heating base 15 of the sole 10 two independent vaporization chambers 28, 29 are formed, separated by a vertical partition 31 and closed by the cover 17.
La première chambre de vaporisation dite principale 28, de grand volume, est destinée à produire un courant continu de vapeur à faible pression en étant alimentée en eau au moyen d'un premier dispositif d'injection (non re¬ présenté) au travers d'une première ouverture 33 prati¬ quée dans le couvercle 17. Cette chambre de vaporisation 28 communique, par l'intermédiaire d'orifices de distri- bution de vapeur 35 débouchant sur la face inférieure 23 de la base 15 (voir figures 2 et 3) , avec des trous de sortie de vapeur 38 percés dans la plaque 21 (voir figure 4) et en relation avec les orifices 35 de distribution de vapeur.The first so-called main vaporization chamber 28, of large volume, is intended to produce a continuous stream of steam at low pressure by being supplied with water by means of a first injection device (not shown) through a first opening 33 practi¬ cated in the cover 17. This vaporization chamber 28 communicates, via steam distribution orifices 35 opening onto the underside 23 of the base 15 (see Figures 2 and 3) , with steam outlet holes 38 drilled in the plate 21 (see Figure 4) and in relation to the steam distribution orifices 35.
Dans cet exemple, les trous 38 de sortie de vapeur sont répartis, d'une part, à proximité des deux bords la¬ téraux 41,42 de la plaque 21, dans la région antérieure de celle-ci, et d'autre part, dans une plage située ap- proximativement dans la région médiane de la plaque 21 grâce à des canaux 44,45 ménagés dans la face inférieure 23 de la base 15 (voir figure 3) et adaptés à répartir la vapeur issue des orifices 35 de distribution de vapeur dans cette région médiane de la plaque 21 via les trous correspondants 38 de ladite plaque 21.In this example, the steam outlet holes 38 are distributed, on the one hand, near the two lateral edges 41, 42 of the plate 21, in the anterior region thereof, and on the other hand, in a range located approximately in the middle region of the plate 21 by means of channels 44, 45 made in the lower face 23 of the base 15 (see FIG. 3) and adapted to distribute the steam coming from the orifices 35 for distributing steam in this central region of the plate 21 via the corresponding holes 38 of said plate 21.
La deuxième chambre de vaporisation 29, de volume notablement inférieur à celui de la première chambre 28, est disposée sensiblement au-dessus de la résistance blindée 18 et en avant de la première chambre 28, et est destinée à produire un courant de vapeur à pression élevée et forte pénétration en étant alimentée en eau au moyen d'un deuxième dispositif d'injection (non représenté) au travers d'une deuxième ouverture 47 pratiquée dans le couvercle 17. Cette chambre de vaporisation 29 communique, par l'intermédiaire d'au moins un passage de vapeur 49 débouchant sur la face inférieure 23 de la base 15 (voir figures 2 et 3) , avec une chambre de distribution de vapeur 51 ménagée dans ladite face inférieure 23 de la base 15 (voir figure 3) et en relation avec des trous de sortie de vapeur 53 percés dans la plaque 21 (figure 4) .The second vaporization chamber 29, of volume significantly less than that of the first chamber 28, is disposed substantially above the armored resistor 18 and in front of the first chamber 28, and is intended to produce a stream of steam at pressure high and high penetration by being supplied with water by means of a second injection device (not shown) through a second opening 47 formed in the cover 17. This vaporization chamber 29 communicates, by means of at least one steam passage 49 opening onto the lower face 23 of the base 15 (see FIGS. 2 and 3), with a steam distribution chamber 51 formed in said lower face 23 of the base 15 (see FIG. 3) and in relationship with steam outlet holes 53 drilled in the plate 21 (Figure 4).
Selon l'invention, la chambre de distribution 51 (figure 3) s'étend dans une région située dans la pointe 11 de la base chauffante 15 de la semelle 10, et les trous 53 de sortie de vapeur (figure 4) en relation avec la chambre de distribution 51 sont groupés dans la pointe 11 de la plaque de repassage 21 de la semelle.According to the invention, the distribution chamber 51 (Figure 3) extends in a region located in the tip 11 of the heating base 15 of the sole 10, and the steam outlet holes 53 (Figure 4) in relation to the distribution chamber 51 are grouped in the tip 11 of the ironing plate 21 of the sole.
De préférence, en regard des figures 3 et 4, la chambre de distribution 51 est une chambre de faible vo¬ lume qui présente un profil symétrique par rapport à l'axe XX' de la base 15, en l'occurrence de forme ap¬ proximativement triangulaire dont le sommet 55 est situé à proximité immédiate, de l'ordre de 1 à 3 centimètres, du sommet 56 de la pointe 11 de la base 15, tandis que les trous correspondants 53 définissent ensemble une plage de vaporisation 57 (délimitée par des traits interrompus sur la figure 4) s'étendant à l'avant de la plaque de repassage 21 et ayant présentement une forme approximativement triangulaire dont le sommet 59 est si¬ tué à proximité immédiate, également de l'ordre de 1 à 3 centimètres, du sommet 61 de la pointe 11 de la plaque 21.Preferably, with reference to FIGS. 3 and 4, the distribution chamber 51 is a chamber of low volume which has a symmetrical profile with respect to the axis XX 'of the base 15, in this case ap¬ approximately triangular, the apex 55 of which is located in the immediate vicinity, of the order of 1 to 3 centimeters, of the apex 56 of the apex 11 of the base 15, while the corresponding holes 53 together define a spray range 57 (delimited by dashed lines in FIG. 4) extending at the front of the ironing plate 21 and presently having an approximately triangular shape whose apex 59 is si¬ killed in the immediate vicinity, also of the order of 1 to 3 centimeters, from the top 61 of the tip 11 of the plate 21.
On comprend que par cette disposition des trous de sortie de vapeur 53 dans la pointe 11 de la semelle 10, la diffusion de vapeur est concentrée tout à l'avant du fer à repasser, de sorte que la pointe 11 de la semelle 10 sert avantageusement de guide pour l'utilisateur lors du repassage, en particulier pour l'exécution délicate du marquage des plis des tissus ou le contoumement des boutons des chemises.It is understood that by this arrangement of the steam outlet holes 53 in the tip 11 of the sole 10, the vapor diffusion is concentrated right at the front of the iron, so that the tip 11 of the sole 10 advantageously serves of guide for the user during ironing, in particular for the delicate execution of the marking of the folds of the fabrics or the circumvention of the buttons of the shirts.
Dans une forme d'exécution préférée illustrée à la figure 3, la face inférieure 23 de la base chauffante 15 est creusée d'une chambre 63 de compression de la vapeur sortant du passage 49 dont le débouché est situé dans la partie centrale postérieure de ladite chambre de compres¬ sion 63 ; cette chambre de compression 63 , de faible vo- lume, est reliée à la chambre de distribution 51 par un petit canal longitudinal rectiligne 65 creusé dans la face inférieure 23 de la base 15 et destiné, par une sorte d'effet Venturi, à acheminer à vitesse élevée la vapeur depuis la chambre de compression 63 jusqu'à la chambre de distribution 51. La chambre de compression 63 est par ailleurs en relation avec des trous correspon¬ dants de sortie de vapeur 68 percés dans la plaque 21 (figure 4), ces trous 68 étant groupés de manière à for¬ mer une plage de vaporisation s'étendant dans la région antérieure de la plaque 21 et destinée à augmenter la qualité du repassage. Dans cet exemple, figure 3, la chambre de compres¬ sion 63 présente une forme approximativement trapézoïdale dont les bases sont sensiblement orthogonales à l'axe XX' de la base chauffante 15. L'ensemble formé par la chambre trapézoïdale de compression 63, le canal rectiligne 65 et la chambre triangulaire de distribution 51 est axé sur l'axe XX' de la base 15, comme on le voit à la figure 3.In a preferred embodiment illustrated in FIG. 3, the underside 23 of the heating base 15 is hollowed out of a chamber 63 for compressing the steam leaving the passage 49, the outlet of which is located in the rear central part of said compression chamber 63; this compression chamber 63, of small volume, is connected to the distribution chamber 51 by a small rectilinear longitudinal channel 65 hollowed out in the lower face 23 of the base 15 and intended, by a sort of Venturi effect, to convey at high speed the steam from the compression chamber 63 to the distribution chamber 51. The compression chamber 63 is moreover in relation to corresponding steam outlet holes 68 drilled in the plate 21 (FIG. 4) , these holes 68 being grouped so as to form a spray range extending in the anterior region of the plate 21 and intended to increase the quality of ironing. In this example, FIG. 3, the compression chamber 63 has an approximately trapezoidal shape whose bases are substantially orthogonal to the axis XX 'of the heating base 15. The assembly formed by the trapezoidal compression chamber 63, the rectilinear channel 65 and the triangular distribution chamber 51 is centered on the axis XX 'of the base 15, as seen in FIG. 3.
Ainsi, lors d'une injection d'eau dans la chambre de vaporisation principale 28 au travers de l'ouverture 33 du couvercle de la semelle 10, l'eau injectée (au point A situé sur l'axe XX' à la figure 2) est vaporisée grâce à la chaleur de la résistance blindée 18. La vapeur chemine dans la chambre 28, traverse les passages dési¬ gnés en 71 et 72 sur la figure 2, s'échappe par les ori¬ fices 35 de distribution de vapeur en se répartissant en partie dans les canaux 44,45, comme illustré par les flè¬ ches en traits pleins sur les figures 2 et 3, et sort en jets continus à faible pression par les trous correspon¬ dants 38 de la plaque de repassage 21.Thus, during an injection of water into the main vaporization chamber 28 through the opening 33 of the cover of the sole 10, the water injected (at point A located on the axis XX 'in FIG. 2 ) is vaporized by the heat of the armored resistor 18. The vapor travels in the chamber 28, crosses the passages designated at 71 and 72 in FIG. 2, escapes through the orifices 35 for distributing steam by partially distributed in the channels 44, 45, as illustrated by the arrows in solid lines in FIGS. 2 and 3, and exits in continuous jets at low pressure through the corresponding holes 38 of the ironing plate 21.
Par ailleurs, lors d'une injection d'eau dans la chambre de vaporisation 29 au travers de l'ouverture 47 du couvercle de la semelle 10, l'eau injectée (au point B situé sur l'axe XX' à la figure 2) est transformée en va¬ peur au contact du métal chauffé par la résistance blin¬ dée 18. La vapeur chemine dans la chambre 29 suivant un parcours sinueux dans le sens des flèches représentées en pointillés sur la figure 2, sort par le passage 49 pour déboucher dans la chambre de compression 63 (figure 3) où une partie de la vapeur s'échappe par les trous de sortie 68 de la plaque 21, puis s'engouffre dans le canal recti¬ ligne 65 pour déboucher à vitesse élevée dans la chambre de distribution 51, comme illustré par les flèches en pointillés sur la figure 3, et s'échappe en jets à pression élevée et forte pénétration par les trous de sortie 53 pratiqués dans la pointe 11 de la plaque de repassage 21. Furthermore, during an injection of water into the vaporization chamber 29 through the opening 47 of the cover of the sole 10, the water injected (at point B located on the axis XX 'in FIG. 2 ) is transformed into va¬ fear in contact with the metal heated by the blin¬ ded resistance 18. The steam travels in the chamber 29 along a winding path in the direction of the arrows shown in dotted lines in Figure 2, exits through the passage 49 for lead into the compression chamber 63 (FIG. 3) where part of the steam escapes through the outlet holes 68 of the plate 21, then rushes into the recti¬ line channel 65 to open at high speed into the chamber dispenser 51, as illustrated by the dotted arrows in FIG. 3, and escapes in jets at high pressure and high penetration through the outlet holes 53 made in the tip 11 of the ironing plate 21.
