Description

La présente invention se rapporte aux fers à repasser électriques à vapeur qui comportent une semelle comprenant une base chauffée au moyen d'une résistance électrique et une plaque de repassage montée sous ladite base ; une chambre de vaporisation dite principale pratiquée dans la base, fermée par un couvercle, alimentée en eau au moyen d'un dispositif d'injection au travers d'une ouverture pratiquée dans le couvercle, et comportant plusieurs passages de vapeur qui débouchent chacun sur la face inférieure de la base et qui sont agencés de manière que la vapeur chemine dans la chambre principale de vaporisation suivant un parcours adapté à favoriser la vaporisation de l'eau avant d'atteindre chaque passage ; et une chambre de distribution de vapeur ménagée dans la face inférieure de la base, communiquant avec le débouché de chaque passage de vapeur et étant en relation avec des trous de sortie de vapeur percés dans la plaque.The present invention relates to irons electric steam ironers with a soleplate comprising a base heated by means of a resistance electric and an ironing board mounted under said base; a so-called main vaporization chamber in the base, closed by a cover, supplied with water by means of an injection device through a opening in the cover, and comprising several steam passages which each lead to the underside of the base and which are arranged so as steam travels through the master bedroom vaporization following a route adapted to promote spraying water before reaching each pass; and a steam distribution chamber provided in the underside of the base, communicating with the outlet of each vapor passage and being related to steam outlet holes drilled in the plate.

Dans des fers à repasser à vapeur connus de ce genre, tels que celui décrit dans le document FR A - 2 290 524, les passages de vapeur sont constitués par des orifices de liaison pratiqués dans la base chauffante et étant en relation avec les trous de sortie de vapeur percés dans la plaque de repassage. Ce type de fer à repasser présente l'inconvénient que de l'eau non vaporisée est susceptible de passer directement de la chambre de vaporisation à la chambre de distribution via les orifices de liaison, entraínant alors des risques de projection de gouttelettes d'eau par les trous de sortie. Les projections d'eau mouillent le linge, ce qui nuit à la qualité du repassage, et après plusieurs cycles thermiques, de petites plaques de calcaire arrivent à passer dans la chambre de distribution, finissant par boucher les orifices de liaison, et donc les trous de sortie.In steam irons known from this genre, such as that described in the document FR A - 2 290 524, the steam passages are formed by connection holes in the base heating and being in connection with the outlet holes steam drilled in the ironing board. This kind of iron has the disadvantage that water is not vaporized is likely to pass directly from the vaporization chamber to the distribution chamber via the connection holes, resulting in risks of projection of water droplets through the outlet holes. Water splashes wet the laundry, which affects the quality of ironing, and after several cycles thermal, small limestone plates arrive at pass into the distribution chamber, ending with plug the connection holes, and therefore the exit.

L'invention a notamment pour but de remédier à ces inconvénients et de réaliser un fer à repasser à vapeur, du type exposé ci-dessus, dont la semelle fasse appel à une conception perfectionnée permettant un repassage de bonne qualité, adaptée à la fabrication en grande série et d'un coût réduit.The object of the invention is in particular to remedy these disadvantages and to make a steam iron, of the type described above, the sole of which uses an advanced design allowing ironing of good quality, suitable for mass production and reduced cost.

Selon l'invention, la chambre principale de vaporisation étant délimitée par une cloison périphérique sur laquelle prend appui le couvercle, les passages de vapeur sont constitués par des cheminées verticales agencées en bordure de ladite cloison périphérique, et s'élevant vers le couvercle en laissant subsister sur au moins une partie un petit espace avec ledit couvercle de manière à permettre le passage de la vapeur par ledit espace en partie haute de chacune des cheminées.According to the invention, the main bedroom of vaporization being delimited by a peripheral partition on which the cover rests, the passages of steam consist of vertical chimneys arranged at the edge of said peripheral partition, and rising towards the cover, leaving on at least part a small space with said cover of so as to allow the passage of steam through said space in the upper part of each chimney.

Ainsi, grâce à ce passage de la vapeur en partie haute des cheminées, les gouttelettes d'eau non vaporisées ne peuvent quasiment pas franchir ces cheminées, et donc passer dans la chambre de distribution sous-jacente, évitant ainsi tout risque de projection d'eau par les trous de sortie, et partant, tout entartrage de la chambre de distribution. De plus, cet échappement de la vapeur par la partie haute des cheminées assure un excellent fonctionnement du fer en position verticale pour défroisser les tissus délicats.So thanks to this steam passage in part high chimneys, water droplets not vaporized can hardly cross these chimneys, and therefore pass into the distribution chamber underlying, thus avoiding any risk of projection of water through the outlet holes, and therefore everything scaling of the distribution chamber. In addition, this steam escaping through the upper part of the chimneys ensures an excellent functioning of the iron in vertical position for smoothing delicate fabrics.

Suivant un exemple de réalisation préféré, les cheminées verticales sont au nombre de deux et sont agencées respectivement sur les deux côtés latéraux opposés de la cloison périphérique de la chambre principale de vaporisation. De préférence, les deux cheminées verticales sont symétriques par rapport à l'axe longitudinal de la semelle et sont situées chacune sensiblement dans la région centrale latérale de la chambre de vaporisation.According to a preferred embodiment, the there are two vertical chimneys and are arranged respectively on the two lateral sides opposite of the peripheral wall of the room main spray. Preferably both vertical chimneys are symmetrical about the axis longitudinal of the sole and are located each substantially in the central lateral region of the vaporization chamber.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels :

The characteristics and advantages of the invention will become apparent from the description which follows, by way of nonlimiting example, with reference to the appended drawings in which:
  • Figure 1 is a cross-sectional view of a sole fitted with a cover of a steam iron according to the invention;
  • Figure 2 is a top view of a heating base of the sole of Figure 1, the cover being removed;

  • Figure 4 is a sectional view along the line IV-IV of Figure 2, the cover being in place; and
  • FIG. 5 is a plan view of the external face of an ironing plate for the sole of FIG. 1.

Dans l'exemple de réalisation illustré aux figures 1 à 5, le fer à repasser électrique à vapeur comporte une semelle, désignée par la référence globale 10 à la figure 1, qui s'étend longitudinalement d'une région formant pointe 12 vers une région formant talon 13 et qui comprend une base ou corps 15 réalisé en un matériau métallique moulé tel que, par exemple, l'aluminium, équipé d'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 5) de la semelle ont le même axe de symétrie longitudinal, noté XX'.In the embodiment illustrated in the figures 1 to 5, the electric steam iron has a sole, designated by the global reference 10 in the figure 1, which extends longitudinally of a region forming point 12 towards a heel region 13 and which comprises a base or body 15 made of a metallic material molded such as, for example, aluminum, fitted of a cover 17 made of sheet metal and heated by means of a resistance armored electric 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 example, chrome steel or stainless steel, mounted on the underside 23 of the heating base 15 by all suitable fixing means, the external face of which 25 forms an ironing surface. The heating base 15 (Figures 2 and 3) and the ironing board 21 (Figure 5) of the sole have the same longitudinal axis of symmetry, noted XX '.

Comme le montrent les figures 1 à 4, dans la base chauffante 15 de la semelle 10 est. pratiquée une chambre de vaporisation dite principale 28 délimitée par une cloison périphérique verticale 30 mieux visible à la figure 2, fermée par le couvercle 17 prenant appui sur la cloison périphérique 30 (voir figure 4), et communiquant avec une chambre de distribution de vapeur, désignée en 32 sur la figure 3 et que l'on décrira par la suite, qui est fermée par la plaque 21 et qui est en relation avec des trous de sortie de vapeur 33 percés dans ladite plaque 21. Comme on le voit à la figure 2, les branches de la résistance blindée 18 en U (symbolisé par les traits interrompus sur la figure 2) sont ceinturées à proximité par la chambre de vaporisation 28.As shown in Figures 1 to 4, in the base heating 15 of the sole 10 is. practiced a room so-called main vaporization 28 delimited by a vertical peripheral partition 30 better visible in the figure 2, closed by the cover 17 bearing on the peripheral partition 30 (see FIG. 4), and communicating with a steam distribution chamber, designated as 32 in FIG. 3 and which will be described later, which is closed by plate 21 and which is related to steam outlet holes 33 drilled in said plate 21. As can be seen in Figure 2, the branches of the armored resistance 18 in U (symbolized by the lines interrupted in Figure 2) are belted nearby through the vaporization chamber 28.

La chambre principale de vaporisation 28, de grand volume, par exemple de l'ordre de 50 cm3, est destinée à produire un courant continu de vapeur à faible pression en étant alimentée en eau au moyen d'un dispositif d'injection (non représenté) au travers d'une ouverture 36 pratiquée dans le couvercle 17.The main vaporization chamber 28, of large volume, for example of the order of 50 cm 3 , is intended to produce a direct current of steam at low pressure by being supplied with water by means of an injection device (not shown) through an opening 36 in the cover 17.

Dans l'exemple de réalisation montré à la figure 2, on a représenté en 38 une longue rainure aux extrémités arrondies qui est creusée horizontalement avec une légère pente vers le bas, par exemple sur l'axe XX', et à très faible profondeur dans la chambre de vaporisation 28 et dont la partie antérieure 41 est destinée à recevoir l'eau tombant au travers de l'ouverture d'injection 36.In the embodiment shown in Figure 2, there is shown at 38 a long groove at the ends rounded which is hollowed out horizontally with a slight slope downwards, for example on the XX 'axis, and at very shallow depth in the vaporization chamber 28 and of which the front part 41 is intended to receive water falling through the injection opening 36.

Selon l'invention, en regard des figures 2 et 3, la chambre principale de vaporisation 28 comporte au moins un passage de vapeur 44 qui débouche sur la face inférieure 23 de la base chauffante 15 et qui est agencé de manière que la vapeur chemine dans la chambre de vaporisation 28 suivant un parcours adapté à favoriser la vaporisation de l'eau avant d'atteindre le passage 44, et la chambre de distribution de vapeur 32 est ménagée dans la face inférieure 23 de la base 15 et est en communication avec le débouché du passage de vapeur 44.According to the invention, with reference to FIGS. 2 and 3, the main vaporization chamber 28 has at least a steam passage 44 which opens onto the underside 23 of the heating base 15 and which is arranged so that the steam flows through the vaporization chamber 28 following a route adapted to favor vaporization of water before reaching passage 44, and the steam distribution chamber 32 is provided in the underside 23 of base 15 and is in communication with the outlet of the steam passage 44.

Dans l'exemple de réalisation représenté sur les figures 2 et 3, il est prévu, à titre purement illustratif mais nullement limitatif, deux passages de vapeur 44 qui sont agencés en bordure interne de la cloison périphérique 30 de la chambre principale de vaporisation 28 pour déboucher dans la chambre de distribution de vapeur 32.In the embodiment shown on the Figures 2 and 3, it is intended, purely by way of illustration but in no way limiting, two steam passages 44 which are arranged on the internal border of the peripheral partition 30 from the main vaporization chamber 28 to open into the steam distribution chamber 32.

Dans cet exemple, les deux passages débouchants de vapeur 44 sont constitués par deux cheminées verticales identiques réalisées respectivement sur les deux côtés latéraux opposés de la cloison périphérique 30 de la chambre de vaporisation 28, et qui sont symétriques par rapport à l'axe XX' en étant situées chacune sensiblement dans la région centrale latérale de la chambre principale de vaporisation 28.In this example, the two through passages of steam 44 consist of two vertical chimneys identical made respectively on both sides opposite sides of the peripheral partition 30 of the vaporization chamber 28, and which are symmetrical by relative to axis XX ', each being located substantially in the central lateral region of the master bedroom spray 28.

Selon un aspect important de l'invention, les deux cheminées latérales 44 s'élèvent vers le couvercle de fermeture 17 en laissant subsister sur au moins une partie un petit espace interne, visible en 46 sur la figure 4, avec le couvercle 17 de manière à permettre le passage de la vapeur par ledit espace 46 en partie haute de chacune des deux cheminées 44. Ainsi, la vapeur ne pouvant quitter la chambre principale de vaporisation 28 qu'en partie haute de chacune des deux cheminées 44, celles-ci ne sont quasiment pas soumises à des projections de gouttelettes d'eau, permettant ainsi d'éviter tout bouchage des trous de la plaque de repassage 21, et partant, d'obtenir une bonne qualité du repassage, même en cas d'un défroissage vertical. According to an important aspect of the invention, the two side chimneys 44 rise towards the cover of closure 17 leaving at least part of it a small internal space, visible at 46 in the figure 4, with the cover 17 so as to allow passage steam through said space 46 in the upper part of each of the two chimneys 44. Thus, the vapor cannot leave the main vaporization chamber 28 that upper part of each of the two chimneys 44, these are practically not subjected to droplet projections of water, thus avoiding any clogging holes of the ironing plate 21, and hence, to obtain good ironing quality, even in the event of vertical steaming.

De plus, chacune des deux cheminées latérales 44 présente une section minimale déterminée de l'ordre d'au moins 20 mm2, cette valeur minimale correspondant à un échappement suffisant de la vapeur en partie haute des deux cheminées en vue d'assurer une diffusion de jets continus de vapeur sur le linge à repasser.In addition, each of the two lateral chimneys 44 has a determined minimum section of the order of at least 20 mm 2 , this minimum value corresponding to sufficient exhaust of the vapor in the upper part of the two chimneys in order to ensure diffusion. continuous jets of steam on the ironing cloth.

Dans le mode d'exécution illustré à la figure 2, chacune des deux cheminées latérales 44 présente une forme sensiblement oblongue et est délimitée verticalement par un tronçon 30a de la cloison périphérique 30 de la chambre principale de vaporisation 28 et une cloison 48 formée dans la chambre de vaporisation 28 et s'étendant à proximité du couvercle 17 de manière à ménager avec celui-ci l'espace interne 46 pour le passage de la vapeur en partie haute de la cheminée 44, voir figure 4.In the embodiment illustrated in Figure 2, each of the two lateral chimneys 44 has a substantially oblong in shape and bounded vertically by a section 30a of the peripheral partition 30 of the main vaporization chamber 28 and a partition 48 formed in the vaporization chamber 28 and extending near the cover 17 so as to spare with this internal space 46 for the passage of the steam in the upper part of the chimney 44, see FIG. 4.

En regard de la figure 3, la chambre de distribution de vapeur 32 est constituée présentement par une rainure creusée dans la face inférieure 23 de la base chauffante 15 et ayant une forme sensiblement en V dont les deux branches 32a,32b s'étendent respectivement le long et à proximité des deux bords latéraux 15a,15b de la base 15 et dont la pointe 50 est située dans la région formant pointe 12 de la base. Dans chacune des deux branches 32a,32b de la rainure de distribution 32 en V débouche l'une des cheminées 44, comme on le voit à la figure 3, et les trous de sortie de vapeur 33 percés dans la plaque 21 (figure 5) sont répartis en coïncidence avec la rainure de distribution 32.Next to Figure 3, the distribution chamber steam 32 is currently made up of a groove in the underside 23 of the base heating 15 and having a substantially V shape of which the two branches 32a, 32b extend respectively the long and close to the two lateral edges 15a, 15b of the base 15 and whose point 50 is located in the region forming point 12 of the base. In each of the two branches 32a, 32b of the V-shaped distribution groove 32 opens one of the chimneys 44, as seen in the figure 3, and the steam outlet holes 33 drilled in the plate 21 (Figure 5) are distributed in coincidence with the distribution groove 32.

Comme le montre la figure 3, dans la face inférieure 23 de la base chauffante 15 est pratiqué également au moins un canal transversal 52, ici au nombre de deux en disposition parallèle, qui débouche aux deux extrémités fibres de la rainure de distribution 32 en V et qui est adapté, par l'intermédiaire d'évidements circulaires 54 de faible profondeur, à acheminer la vapeur véhiculée dans la rainure 32 dans une plage située approximativement dans la région postérieure transversale de la plaque de repassage 21 via des trous correspondants de sortie de vapeur 56 percés dans la plaque 21 et en coïncidence avec les évidements 54 de chaque canal 52.As shown in Figure 3, on the underside 23 of the heating base 15 is also practiced at least one transverse channel 52, here two in number in parallel arrangement, which opens at both ends fibers of the distribution groove 32 in V and which is adapted, by means of circular recesses 54 shallow, to convey conveyed steam in groove 32 in a range approximately in the posterior transverse region of the plate ironing 21 via corresponding outlet holes of steam 56 drilled in plate 21 and coinciding with the recesses 54 of each channel 52.

En regard de la figure 2, à l'intérieur de la chambre principale de vaporisation 28 sont ménagées deux chambres identiques de décantation 60, de volume respectif faible comparativement à celui de la chambre principale de vaporisation 28, de l'ordre de 5 cm3 chacune dans l'exemple choisi, qui sont associées respectivement aux deux cheminées 44 et qui comportent chacune un petit passage, visible en 62 sur la figure 4, destiné à y faire entrer la vapeur cheminant dans la chambre principale de vaporisation 28. Les deux chambres de décantation 60 sont disposées respectivement au-dessus des deux branches latérales de la résistance blindée 18 en U, comme représenté schématiquement sur la figure 2 ; la résistance blindée 18 s'étend de façon adjacente à chacune des deux cheminées latérales 44.With reference to FIG. 2, inside the main vaporization chamber 28 are formed two identical decantation chambers 60, of respective small volume compared to that of the main vaporization chamber 28, of the order of 5 cm 3 each in the example chosen, which are respectively associated with the two chimneys 44 and which each have a small passage, visible at 62 in FIG. 4, intended to bring in the steam passing through the main vaporization chamber 28. The two chambers settling tank 60 are disposed respectively above the two lateral branches of the armored resistor 18 in a U, as shown diagrammatically in FIG. 2; the armored resistance 18 extends adjacent to each of the two lateral chimneys 44.

Plus précisément, dans le mode d'exécution illustré à la figure 2, chacune des deux chambres de décantation 60 est délimitée verticalement par un tronçon 30b de la cloison périphérique 30 de la chambre principale de vaporisation 28 qui prolonge l'arrière du tronçon 30a de cette cloison périphérique 30, la cloison 48 servant à délimiter la cheminée associée 44, et une cloison 64 présentant, d'une part, un tronçon longitudinal 64a se raccordant à l'avant du tronçon 30a de la cloison périphérique 30 en bordant la cheminée 44 et s'étendant à la même hauteur que la cloison périphérique 30 de sorte que le couvercle 17 prend également appui sur ce tronçon longitudinal 64a (voir figure 4), et d'autre part, un tronçon transversal 64b se raccordant au tronçon 30b de la cloison périphérique 30 et s'étendant à proximité du couvercle 17 de manière à ménager avec celui-ci un interstice formant le passage d'entrée 62 (figure 4) de la vapeur dans la chambre de décantation 60.More specifically, in the illustrated embodiment in Figure 2, each of the two settling chambers 60 is delimited vertically by a section 30b of the peripheral partition 30 of the main vaporization chamber 28 which extends the rear of the section 30a of this peripheral partition 30, the partition 48 serving to delimit the associated chimney 44, and a partition 64 presenting, on the one hand, a longitudinal section 64a connecting at the front of the section 30a of the peripheral partition 30 bordering the chimney 44 and extending to the same height as the peripheral wall 30 so the cover 17 is also supported on this longitudinal section 64a (see Figure 4), and on the other hand, a section transverse 64b connecting to the section 30b of the partition peripheral 30 and extending near the cover 17 so as to form a gap therewith forming the inlet passage 62 (figure 4) of the steam in the settling chamber 60.

Ainsi, chacune des deux chambres de décantation 60 remplit avantageusement à la fois la fonction de vaporisation instantanée de toute gouttelette d'eau entrant dans la chambre de décantation par le passage 62 et celle de piège ou de récupération des plaques de calcaire susceptibles de s'y former.Thus, each of the two settling chambers 60 advantageously fulfills both the vaporization function instant of any incoming water droplet in the settling chamber through passage 62 and that trap or recovery of limestone plaques likely to train there.

Lors d'une injection d'eau dans la chambre principale de vaporisation 28, et présentement au niveau de la partie antérieure 41 de la rainure longitudinale 38 creusée dans la chambre de vaporisation 28, au travers de l'ouverture 36 du couvercle 17 de la semelle 10, l'eau injectée (au point A situé sur l'axe XX' à la figure 2) est transformée en vapeur au contact du métal chauffé par la résistance blindée 18. La vapeur chemine dans la rainure 38 de la chambre 28 en étant guidée par cette rainure 38, entre par chacun des deux passages 62 (voir figure 4) dans la chambre de décantation correspondante 60 où d'éventuelles gouttelettes d'eau y pénétrant sont vaporisées instantanément, puis s'échappe en partie haute de chacune des deux cheminées 44 par le petit espace 46 (voir figure 4) pour déboucher dans la branche latérale correspondante 32a;32b de la rainure de distribution de vapeur 32 en V, comme indiqué par les flèches représentées sur la figure 2.During an injection of water into the main vaporization chamber 28, and presently at the level of the front part 41 of the longitudinal groove 38 hollowed out in the vaporization chamber 28, through the opening 36 of the cover 17 of the sole 10, the water injected (at point A located on the axis XX ′ in FIG. 2) is transformed into vapor in contact with the metal heated by the armored resistance 18. The vapor travels in the groove 38 of the chamber 28 being guided by this groove 38, enters through each of the two passages 62 (see FIG. 4) into the corresponding decantation chamber 60 where any droplets of water entering it are vaporized instantaneously, then escapes in the upper part of each of the two chimneys 44 through the small space 46 (see FIG. 4) to open into the corresponding lateral branch 32a; 32b of the steam distribution groove 32 in V, as indicated by the arrows shown in FIG. 2.

De là, la vapeur est véhiculée dans la rainure de distribution 32 en se répartissant en partie dans chacun des deux canaux transversaux 52, comme montré par les flèches représentées sur la figure 3, et s'échappe en jets continus à faible pression par les trous correspondants 33 et 56 de la plaque de repassage 21.From there, the vapor is conveyed in the groove of distribution 32 by being partly distributed in each of the two transverse channels 52, as shown by arrows shown in Figure 3, and escapes in continuous low pressure jets through corresponding holes 33 and 56 of the ironing board 21.
