Description

FER A REPASSER COMPORTANT UNE POMPE A MELANGE D'EAU ET IRON COMPRISING A WATER MIXED PUMP AND
D'ADJUVANT TEXTILETEXTILE ADJUVANT
La présente invention concerne un fer à repasser, notamment à vapeur, comportant un réservoir d'eau, un réservoir contenant un ad uvant textile, et une pompe comprenant une chambre de mélange et propre, d'une part, à aspirer dans la chambre de mélange une dose d'eau du réservoir d'eau ainsi que l'adjuvant du réservoir d'adju- vant via un robinet permettant de doser l'adjuvant, de manière à produire dans la chambre de mélange une solution diluée de l'adjuvant, et d'autre part, à envoyer cette solution vers un dispositif de pulvérisation situé dans la partie antérieure du fer.The present invention relates to an iron, in particular a steam iron, comprising a water tank, a tank containing a textile fabric, and a pump comprising a mixing chamber and clean, on the one hand, to be sucked into the mix a dose of water from the water tank as well as the adjuvant from the adjuvant tank via a tap allowing the dosage of the adjuvant, so as to produce in the mixing chamber a dilute solution of the adjuvant, and on the other hand, to send this solution to a spraying device located in the front part of the iron.
On sait qu'avec un tel fer, la* pulvérisation sur le linge d'un produit actif dilué sert à faciliter le repassage tout en améliorant la glisse et en effaçant les fauxWe know that with such an iron, * spraying the linen with a diluted active product serves to facilitate ironing while improving gliding and erasing scythes
Dans un fer à repasser connu de ce genre, le réservoir d'eau est relié à la pompe d'aspiration par un tube capillaire, tandis que le robinet permettant de doser l'adjuvant est également relié à la pompe par un autre tube capillaire. Un tel agencement de ces divers organes est particulièrement disparate et encombrant et est difficile à réaliser lors de la fabrication du fer.In a known iron of this kind, the water tank is connected to the suction pump by a capillary tube, while the tap for dosing the adjuvant is also connected to the pump by another capillary tube. Such an arrangement of these various members is particularly disparate and bulky and is difficult to produce during the manufacture of iron.
L'invention a notamment pour but de remédier à ces inconvénients et de réaliser un fer à repasser, du type exposé ci -dessus, dans lequel les organes de pompage et de dosage de l'adjuvant soient regroupés, ceci en vue de simplifier leur implantation dans le fer. Dans un fer selon l'invention, la pompe est du type à piston se déplaçant dans un corps et délimitant dans la partie inférieure du corps la chambre de mélange qui débouche dans le réservoir d'eau via un clapet anti-retour, et cette pompe fait également office de robinet de dosage de 1 ' adj uvant .The object of the invention is in particular to remedy these drawbacks and to produce an iron, of the type described above, in which the pumping and metering members of the adjuvant are grouped together, this in order to simplify their installation. in the iron. In an iron according to the invention, the pump is of the piston type moving in a body and delimiting in the lower part of the body the mixing chamber which opens into the water tank via a non-return valve, and this pump also acts as a dosing tap for the adjuvant.
La pompe et le robinet de dosage de l'adjuvant sont ainsi groupés en un ensemble unitaire compact. De sur- croît, la pompe remplit avantageusement à elle seule une double fonction, à savoir celle de pompage pour aspirer l'eau et l'adjuvant, et celle de dosage de l'adjuvant destiné à être mélangé à l'eau aspirée, constituant ainsi en soi une véritable pompe de dosage d'un mélange d'eau et d'adjuvant textile. Une telle pompe doseuse peut êtreThe pump and the adjuvant dosing tap are thus grouped into a compact unitary assembly. In addition, the pump advantageously fulfills by itself a double function, namely that of pumping to suck up the water and the adjuvant, and that of dosing the adjuvant intended to be mixed with the sucked water, constituting thus in itself a real dosing pump of a mixture of water and textile additive. Such a metering pump can be
» réalisée sous la forme d'une petite pompe, donc à faible encombrement dans le fer.»Produced in the form of a small pump, therefore compact in the iron.
Selon un mode d'exécution de l'invention, le piston comprend deux organes mobiles distants d'ouverture- fermeture, respectivement dits supérieur et inférieur, montés dans le corps de la pompe en délimitant entre eux une chambre de dosage, et commandés respectivement par des premiers et seconds moyens d ' actionnement liés au piston, lesdits organes supérieur et inférieur étant mobiles entre une position de repos dans laquelle l'organe supérieur est ouvert, tandis que l'organe inférieur est fermé, de manière à permettre le passage d'une dose d'adjuvant depuis le réservoir d'adjuvant vers la chambre de dosage, et une position de travail dans laquelle l'organe supérieur se ferme sous l'action des premiers moyens d ' actionnement , tandis que l'organe inférieur s'ouvre sous l'action des seconds moyens d ' actionnement , de ma- nière a permettre le passage de la dose d'adjuvant depuis la chambre de dosage vers la chambre de mélange.According to one embodiment of the invention, the piston comprises two movable remote opening-closing members, called upper and lower respectively, mounted in the pump body by delimiting between them a metering chamber, and controlled respectively by first and second actuation means linked to the piston, said upper and lower members being movable between a rest position in which the upper member is open, while the lower member is closed, so as to allow passage of a dose of adjuvant from the adjuvant tank to the metering chamber, and a working position in which the upper member closes under the action of the first actuation means, while the lower member opens under the action of the second actuation means, ma- to allow the passage of the dose of adjuvant from the dosing chamber to the mixing chamber.
Les deux organes mobiles d ' ouverture-fermeture, dé- limitant entre eux la chambre de dosage, jouent ainsi ensemble le rôle d'un robinet intégré à la pompe proprement dite et adapté à doser l'adjuvant destiné à être mélangé à l'eau aspirée par la pompe.The two movable open-close members, delimiting between them the metering chamber, thus together play the role of a valve integrated into the pump proper and suitable for dosing the adjuvant intended to be mixed with water. drawn by the pump.
Suivant une autre caractéristique de l'invention, le réservoir d'adjuvant fait partie intégrante de la pompe. Ainsi, la pompe doseuse et le réservoir d'adjuvant constituent avantageusement un ensemble unitaire qualifié de particulièrement compact.According to another characteristic of the invention, the adjuvant reservoir forms an integral part of the pump. Thus, the metering pump and the adjuvant tank advantageously constitute a unitary unit qualified as particularly compact.

Le fer à repasser 1 représenté schématiquement à la figure 1 comprend essentiellement une semelle de repas- sage 2 , un capot 3 et une poignée 4 surmontant le capot .The iron 1 shown diagrammatically in FIG. 1 essentially comprises an ironing sole 2, a cover 3 and a handle 4 surmounting the cover.
A 1 ' intérieur du capot 3 sont logés tous les organes classiques d'un fer à repasser. Sous le capot 3 est logé en particulier un réservoir 5 contenant de l'eau sans ad- uvant .Inside the cover 3 are housed all the conventional organs of an iron. Under the cover 3 is housed in particular a tank 5 containing water without additives.
Comme le montre la figure 1, le fer à repasser est équipé en outre d'un ensemble unitaire, désigné par le repère général 10, qui est formé par un réservoir 12 contenant un adjuvant textile 13, une unique pompe manuelle d'aspiration 15 et un dispositif de pulvérisation 16, de structure connue en soi, situé dans la région antérieure du fer.As shown in FIG. 1, the iron is further equipped with a unitary assembly, designated by the general reference 10, which is formed by a reservoir 12 containing a textile additive 13, a single manual suction pump 15 and a spray device 16, of known structure, located in the anterior region of the iron.
L'adjuvant textile 13 contenu dans le réservoir 12 est, de préférence, un produit actif concentré du type qualifié d'aide au repassage, composé notamment d'amidon, d'eau et d'un produit conservateur, et susceptible d'être mélangé à tous types d'eau.The textile additive 13 contained in the reservoir 12 is preferably a concentrated active product of the type qualified as an ironing aid, composed in particular of starch, water and a preservative, and capable of being mixed with all types of water.
La pompe 15 comprend un corps tubulaire cylindrique 18, d'axe de symétrie vertical XX', réalisé par moulage en matière plastique et comportant une chambre de mélange 20. La pompe 15 est propre, d'une part, à aspirer dans cette chambre de mélange 20 une dose d'eau du réservoir d'eau 5 ainsi qu'une dose prédéterminée d'adjuvant du réservoir 12, de manière à produire dans la chambre de mélange 20 une solution diluée de l'adjuvant, et d'autre part, à envoyer cette solution vers le dispositif αe pulvérisation 16. La solution diluée de l'adjuvant, après pulvérisation sur le tissu à repasser, sert de manière avantageuse à faciliter le repassage tout en améliorant la glisse et en éliminant les faux plis.The pump 15 comprises a cylindrical tubular body 18, of vertical axis of symmetry XX ′, produced by molding in plastic material and comprising a mixing chamber 20. The pump 15 is clean, on the one hand, to be sucked into this mixes 20 a dose of water from the water reservoir 5 as well as a predetermined dose of adjuvant from the reservoir 12, so as to produce in the mixing chamber 20 a dilute solution of the adjuvant, and on the other hand, to send this solution to the spraying device 16. The diluted solution of the adjuvant, after spraying on the fabric to be ironed, advantageously serves to facilitate ironing while improving the glide and eliminating creases.
Comme le montrent mieux les figures 2, 7, 8 et 9, la pompe 15 est du type à piston 22 se déplaçant verticalement dans le corps 18 de la pompe en étant lié à un ressort de rappel 23 disposé axialement . Le piston 22 délimite dans la partie inférieure du corps 18 la chambre de mélange 20 qui débouche dans le réservoir d'eau 5 via un clapet anti-retour constitué présentement par une bille 25 coopérant avec un siège conique 26.As best shown in Figures 2, 7, 8 and 9, the pump 15 is of the piston type 22 moving vertically in the body 18 of the pump by being linked to a return spring 23 disposed axially. The piston 22 delimits in the lower part of the body 18 the mixing chamber 20 which opens into the water tank 5 via a non-return valve presently constituted by a ball 25 cooperating with a conical seat 26.
Dans cet exemple de réalisation, voir figures 2, 7, 8 et 9, le réservoir d'adjuvant 12 fait partie intégrante de la pompe 15 et est monté fixe et d'une manière étan- che , par exemple par une soudure au miroir, sur la partie supérieure du corps 18 de la pompe en étant traversé par le piston 22 ; le réservoir d'adjuvant 12 présente une paroi supérieure 27 traversée par le piston 22, et une paroi de fond 28 qui débouche directement dans la partie supérieure du corps 18 de la pompe 15.In this exemplary embodiment, see FIGS. 2, 7, 8 and 9, the adjuvant reservoir 12 forms an integral part of the pump 15 and is mounted fixed and in a sealed manner, for example by mirror welding, on the upper part of the body 18 of the pump while being crossed by the piston 22; the adjuvant reservoir 12 has an upper wall 27 through which the piston 22 passes, and a bottom wall 28 which opens directly into the upper part of the body 18 of the pump 15.
Dans cet exemple, le dispositif de pulvérisation 16 fait lui aussi partie intégrante de la pompe 15 et, de préférence, vient de moulage avec le corps 18 de la pompe ; ce dispositif de pulvérisation 16 comprend un conduit d'admission 30 qui débouche dans la chambre de mélange 20 de la pompe 15 via un clapet anti-retour consti- tué présentement par une bille 31 coopérant avec un siège conique 32.In this example, the spraying device 16 is also an integral part of the pump 15 and, preferably, is molded with the body 18 of the pump; this spraying device 16 comprises an intake duct 30 which opens into the mixing chamber 20 of the pump 15 via a non-return valve presently constituted by a ball 31 cooperating with a conical seat 32.
Conformément à l'invention, la pompe 15 fait également office de robinet, désigné par le repère général 34, permettant de doser l'adjuvant destiné à être mélangé à l'eau du réservoir 5, en vue de réaliser un mélange proportionné d'eau et d'adjuvant dans un rapport de dilution déterminé .In accordance with the invention, the pump 15 also acts as a tap, designated by the general reference 34, making it possible to dose the adjuvant intended to be mixed with the water from the tank 5, with a view to producing a proportional mixture of water. and adjuvant in a determined dilution ratio.
Ainsi, la pompe 15 sert non seulement à aspirer l'eau et l'adjuvant, mais aussi à doser l'adjuvant destiné à être mélangé à l'eau, constituant ainsi en soi une véritable pompe doseuse d'un mélange d'eau et d'adjuvant, susceptible par ailleurs d'être réalisée sous la forme d'une petite pompe compacte.Thus, the pump 15 serves not only to suck up the water and the adjuvant, but also to dose the adjuvant intended to be mixed with the water, thus constituting in itself a real dosing pump of a mixture of water and adjuvant, which could moreover be produced in the form of a small compact pump.
A titre d'exemple, l'adjuvant étant un produit concentré, la pompe 15 assure le mélange du produit concentré avec l'eau dans un rapport de dilution choisi d'envi- ron 1/8. Dans cet exemple, le réservoir de produit concentré 12 a une capacité de 20 cm3, tandis que le réservoir d'eau 5 a une capacité de l'ordre de 300 cm3. Selon un mode de réalisation illustré aux figuresBy way of example, the adjuvant being a concentrated product, the pump 15 mixes the concentrated product with the water in a dilution ratio chosen of about 1/8. In this example, the concentrated product tank 12 has a capacity of 20 cm 3 , while the water tank 5 has a capacity of about 300 cm 3 . According to an embodiment illustrated in the figures
2, 7, 8 et 9, le piston 22 est constitué par une tige 36 moulée en une matière plastique, mieux visible à la figure 3, et comprenant deux organes mobiles distants d'ou- verture-fermeture constitués ici respectivement par deux joints annulaires d ' étanchéité , dits supérieur 37 et inférieur 41, qui sont montés mobiles dans le corps 18 de la pompe en étant traversés par la tige 36 et en délimitant entre eux une chambre de dosage 45. Ces deux joints annulaires 37 et 41 présentent chacun un pourtour externe qui est en appui serré contre la face latérale interne 46 du corps 18 de la pompe, formant ainsi une étanchéité permanente sur la surface intérieure du corps de la pompe, et un pourtour interne qui est espacé à distance radiale de la tige 36.2, 7, 8 and 9, the piston 22 is constituted by a rod 36 molded in a plastic material, better visible in FIG. 3, and comprising two distant movable members for opening-closing constituted here respectively by two annular seals sealing, called upper 37 and lower 41, which are mounted movable in the body 18 of the pump being traversed by the rod 36 and delimiting between them a metering chamber 45. These two annular seals 37 and 41 each have a outer periphery which is pressed tightly against the internal lateral face 46 of the body 18 of the pump, thus forming a permanent seal on the inner surface of the pump body, and an internal periphery which is spaced at a radial distance from the rod 36.
Les deux joints mobiles 37 et 41 sont destinés à être commandés respectivement par des premiers et des seconds moyens d ' actionnement comportant présentement cha- cun deux disques, dits supérieur (38 ; 42) et inférieur (39 ; 43), qui sont portés fixes transversalement par la tige 36 en venant avantageusement de moulage avec celle- ci, et qui sont associés par paire respectivement aux deux joints (37 ; 41) en étant disposés de part et d'au- tre de chaque joint. Chacun des quatre disques (38, 39, 42, 43) présente un diamètre qui est légèrement inférieur au diamètre interne du corps 18 de la pompe 15.The two movable seals 37 and 41 are intended to be controlled respectively by first and second actuation means currently comprising each two discs, called upper (38; 42) and lower (39; 43), which are carried fixed. transversely by the rod 36 advantageously coming from molding with the latter, and which are associated in pairs respectively to the two seals (37; 41) being arranged on either side of each seal. Each of the four discs (38, 39, 42, 43) has a diameter which is slightly less than the internal diameter of the body 18 of the pump 15.
Les deux disques, respectivement supérieur 38 et inférieur 43, associés respectivement aux joints supérieur 37 et inférieur 41, sont constitués par des disques pleins, tandis que les deux autres disques homologues, à savoir les disques inférieur 39 et supérieur 42, associés respectivement aux joints supérieur 37 et inférieur 41, sont ajourés. A tit; e d'exemple, en regard des figures 5 et 6, les deux disques ajourés 39 et 42, dont l'un (39) est de diamètre légèrement supérieur à l'autre disque 42, sont constitués chacun par deux paires orthogonales de nervures diamétralement opposées, repérées en 47 sur la figure 5 et en 48 sur la figure 6, définissant ainsi entre elles des évidements (49, figure 5 ; 50, figure 6) destinés au passage de l'adjuvant.The two discs, respectively upper 38 and lower 43, associated respectively with upper 37 and lower seals 41, are constituted by solid discs, while the other two homologous discs, namely the lower 39 and upper 42 discs, respectively associated with seals upper 37 and lower 41, are openwork. A tit; e example, with reference to Figures 5 and 6, the two perforated discs 39 and 42, one of which (39) is slightly larger in diameter than the other disc 42, each consist of two orthogonal pairs of diametrically ribs opposite, identified at 47 in FIG. 5 and at 48 in FIG. 6, thus defining between them recesses (49, FIG. 5; 50, FIG. 6) intended for the passage of the adjuvant.
Les deux joints 37 et 41, en association avec leurs deux disques respectifs (38, 39 ; 42, 43) , forment ainsi des clapets qui sont mobiles en translation verticale entre :The two seals 37 and 41, in association with their respective respective discs (38, 39; 42, 43), thus form valves which are movable in vertical translation between:
- une position de repos (figure 7) dans laquelle le joint supérieur 37 est ouvert en étant en appui sur le disque ajouré associé 39 et espacé du disque plein associé 38, tandis que le joint inférieur 41 est fermé en étant en appui étanche sur le disque plein associé 43 et espacé du disque ajouré associé 42, de manière à permet- tre le passage d'une dose d'adjuvant depuis le réservoir d'adjuvant 12 vers la chambre de dosage 45 de la pompe 15 via les évidements 49 (figure 5) du disque 39 ; et une position de travail (figure 8) dans laquelle le joint supérieur 37 se ferme en appui étanche sur le disque plein associé 38, tandis que le joint inférieur 41 s'ouvre en étant en appui sur le disque ajouré associé 42, de manière à permettre le passage de la dose d'adjuvant depuis la chambre de dosage 45 vers la chambre de mélange 20 de la pompe 15 via les évidements 50 (figure 6) du disque 42.- A rest position (FIG. 7) in which the upper seal 37 is open while bearing on the associated perforated disc 39 and spaced from the associated solid disc 38, while the lower seal 41 is closed while being in tight seal on the associated full disc 43 and spaced from the associated perforated disc 42, so as to allow the passage of a dose of adjuvant from the adjuvant reservoir 12 to the metering chamber 45 of the pump 15 via the recesses 49 (FIG. 5) disc 39; and a working position (FIG. 8) in which the upper seal 37 closes by sealingly pressing on the associated solid disc 38, while the lower seal 41 opens by bearing on the associated perforated disc 42, so as to allow the dose of adjuvant to pass from the metering chamber 45 to the mixing chamber 20 of the pump 15 via the recesses 50 (FIG. 6) of the disc 42.
Comme le montre la figure 3, la tige 36 du piston 22 comprend une pluralité de tronçons reliés entre eux, en l'occurrence au nombre de trois repérés en 51, 52 et 53 sur cette figure 3, qui sont de longueurs différentes et qui ont une forme identique de section constituée présentement par deux paires orthogonales de nervures radiales diamétralement opposées, repérées en 55 sur la figure 4 pour le tronçon supérieur 53 de la tige.As shown in FIG. 3, the rod 36 of the piston 22 comprises a plurality of sections linked together, in this case three in number identified at 51, 52 and 53 in this FIG. 3, which are of different lengths and which have an identical shape of section presently constituted by two orthogonal pairs of diametrically opposite radial ribs, identified at 55 in FIG. 4 for the upper section 53 of the rod.
En regard des figures 2 et 7 , la paroi supérieure 27 du réservoir d'adjuvant 12 est surmontée d'un col ouvert 57 qui est traversé par les nervures 55 formant le tronçon supérieur 53 de la tige 36, et dans lequel est monté un bouchon 59 comprenant présentement une queue cylindrique 60, axée verticalement sur l'axe XX' en étant en appui contre les bords libres des nervures 55, coopérant avec le col 57 au moyen d'organes de fixation mdé- montables 62, d'une structure connue en soi, et se terminant à sa partie supérieure par une 'tête 64 percée d'une ouverture centrale 65 située au-dessus et à l'aplomb de l'extrémité supérieure 67 de la tige 36.With reference to FIGS. 2 and 7, the upper wall 27 of the adjuvant reservoir 12 is surmounted by an open neck 57 which is crossed by the ribs 55 forming the upper section 53 of the rod 36, and in which a plug is mounted 59 presently comprising a cylindrical shank 60, vertically oriented on the axis XX 'while bearing against the free edges of the ribs 55, cooperating with the neck 57 by means of removable fixing members 62, of a known structure per se, and ending at its upper part with a 'head 64 pierced with a central opening 65 situated above and vertically above the upper end 67 of the rod 36.
Le bouchon 59 est déplaçable, par exemple en translation verticale, entre une position haute (figure 2) dans laquelle l'ouverture 65 de la tête 64 du bouchon est dégagée de l'extrémité supérieure 67 de la tige 36 et constitue une ouverture de remplissage d'adjuvant, et une position basse (figure 7) dans laquelle l'ouverture de la tête 64 du bouchon est obturée par l'extrémité supérieure 67 de la tige 36 après remplissage du réservoir d'adjuvant 12.The plug 59 is movable, for example in vertical translation, between a high position (FIG. 2) in which the opening 65 of the head 64 of the plug is released from the upper end 67 of the rod 36 and constitutes a filling opening of adjuvant, and a low position (FIG. 7) in which the opening of the head 64 of the plug is closed by the upper end 67 of the rod 36 after filling of the adjuvant reservoir 12.
Ainsi, le remplissage du réservoir d'adjuvant 12 s'effectue d'une manière aisée par l'utilisateur. Celui- ci lève légèrement le Douchon 59 pour dégager l'ouverture 65, comme illustré à la figure 2, puis introduit dans cette dernière, suivant la flèche F sur la figure 2, l'adjuvant contenu, par exemple, dans un flacon de même capacité que le réservoir 12. L'adjuvant s'écoule dans le réservoir 12 par passage entre les nervures 55 formant le tronçon supérieur 53 de la tige 36.Thus, the filling of the adjuvant reservoir 12 is carried out in an easy manner by the user. The latter slightly lifts the Sleeve 59 to release the opening 65, as illustrated in FIG. 2, then introduced into the latter, according to the arrow F in FIG. 2, the adjuvant contained, for example, in a bottle of the same capacity as the reservoir 12. The adjuvant flows into the reservoir 12 by passing between the ribs 55 forming the upper section 53 of the rod 36.
Lors du remplissage du réservoir d'adjuvant 12, une dose d'adjuvant pénètre dans la chambre de dosage 45 de la pompe 15 grâce à l'ouverture du joint supérieur formant clapet 37 et à la fermeture étanche du joint infé- rieur formant clapet 41, comme on le voit bien à la figure 7.When filling the adjuvant reservoir 12, a dose of adjuvant enters the metering chamber 45 of the pump 15 by virtue of the opening of the upper seal forming a valve 37 and the leaktight closing of the lower seal forming valve 41 , as can be seen in Figure 7.
Après remplissage du réservoir d'adjuvant 12, l'utilisateur repousse le bouchon 59 pour fermer l'ouver- ture 65 dans laquelle s'adapte exactement l'extrémité supérieure 67 de la tige 36, comme illustré à la figure 7.After filling the adjuvant reservoir 12, the user pushes back the plug 59 to close the opening 65 in which the upper end 67 of the rod 36 fits exactly, as illustrated in FIG. 7.
Il convient de noter que le fait de rendre imperdable le bouchon 59 du réservoir d'adjuvant 12 est particu- lièrement plaisant pour l'utilisateur.It should be noted that making the cap 59 of the adjuvant reservoir 12 captive is particularly pleasant for the user.
D'une manière avantageuse, la tête 64 du bouchon 59, après remplissage et fermeture du réservoir d'adjuvant 12 (figure 7), constitue en soi un bouton-poussoir de commande manuelle de la tige formant piston 36, permettant ainsi de réaliser d'une seule pièce les organes de remplissage d'adjuvant et de commande manuelle du piston de la pompe doseuse 15.Advantageously, the head 64 of the plug 59, after filling and closing the adjuvant reservoir 12 (FIG. 7), constitutes in itself a push button for manual control of the piston rod 36, thus making it possible to carry out '' one piece the adjuvant filling members and manual control of the piston of the dosing pump 15.
On a représenté en 69 sur les figures 2, 7, 8 et 9 un soufflet souple qui est interposé entre la paroi supérieure du réservoir d'adjuvant 12, autour du col 57 de celui-ci, .et la tête 64 du bouchon 59. A la base du soufflet 69 est pratiqué un évent périphérique 71 destiné à permettre le pliage et dépliage du soufflet. L'ensemble unitaire 10 formé par le réservoir d'adjuvant 12, la pompe doseuse 15 et le dispositif de pulvérisation 16 constitue un ensemble compact qui est monté amovible dans le capot 3 du fer à repasser.There is shown at 69 in FIGS. 2, 7, 8 and 9 a flexible bellows which is interposed between the upper wall of the adjuvant reservoir 12, around the neck 57 of the latter, and the head 64 of the plug 59. At the base of the bellows 69 is formed a peripheral vent 71 intended to allow the folding and unfolding of the bellows. The unitary assembly 10 formed by the adjuvant reservoir 12, the metering pump 15 and the spraying device 16 constitutes a compact assembly which is removably mounted in the cover 3 of the iron.
Dans l'exemple de réalisation montré à la figure 1, cet ensemble unitaire amovible 10 est implanté dans la partie antérieure du fer, et le bouton-poussoir de la pompe doseuse 15, constitué par la tête 64 du bouchon 59, est positionné par rapport à la poignée 4 à une hauteur telle que l'utilisateur pourra manoeuvrer la pompe 15 sans avoir pratiquement à changer la place de sa main sur la poignée du fer.In the embodiment shown in Figure 1, this removable unitary assembly 10 is located in the front part of the iron, and the push button of the metering pump 15, constituted by the head 64 of the plug 59, is positioned relative to the handle 4 at a height such that the user can maneuver the pump 15 without practically having to change the place of his hand on the handle of the iron.
Dans cet exemple, figure 1, le réservoir d'adjuvant 12 est en quasi-totalité en de la partie antérieure du fer et est transparent, rendant ainsi visible le niveau d'adjuvant.In this example, Figure 1, the adjuvant tank 12 is almost entirely in of the front part of the iron and is transparent, thus making visible the level of adjuvant.
Pour utiliser le fer à repasser, après remplissage et fermeture du réservoir d'adjuvant 12 (figure 7) , l'utilisateur appuie sur la tête 64 du bouchon 59, ce qui a pour effet de plier le soufflet 69, de manière à faire descendre la tige formant piston 36 à l' encontre du res- sort 23. Au cours de cette descente, le joint supérieur formant clapet 37 se ferme, tandis que le joint inférieur formant clapet 41 s'ouvre, permettant ainsi à la dose d'adjuvant contenue dans la chambre de dosage 45 de passer dans la chambre de mélange 20 de la pompe. Puis, l'utilisateur relâche la tête 64 du bouchon 59, de sorte que la tige formant piston 36 remonte sous l'effet du ressort 23, tandis que le soufflet 69 se déplie. Au cours de cette remontée de la tige 36, le clapet 25 s'ouvre et une dose d'eau du réservoir 5 est aspirée dans la chambre de mélange 20 dans Laquelle l'eau et l'adjuvant se mélangent pour produire αne solution diluée d'adjuvant dans le rapport de dilution choisi. En fin de remontée de la tige 36, le joint inférieur formant clapet 41 se ferme, tandis que le joint supérieur formant clapet 37 s'ouvre, permettant ainsi à une nouvelle dose d'adjuvant de pénétrer dans la chambre de dosage 45 de la pompe. La pompe 15 est ainsi amorcée, comme illustré à la figure 7.To use the iron, after filling and closing the adjuvant reservoir 12 (FIG. 7), the user presses on the head 64 of the plug 59, which has the effect of folding the bellows 69, so as to bring down the rod forming the piston 36 against the spring 23. During this descent, the upper seal forming the valve 37 closes, while the lower seal forming the valve 41 opens, thus allowing the dose of adjuvant contained in the metering chamber 45 to pass into the mixing chamber 20 of the pump. Then, the user releases the head 64 of the plug 59, so that the piston rod 36 rises under the effect of the spring 23, while the bellows 69 unfolds. During this ascent of the rod 36, the valve 25 opens and a dose of water from the reservoir 5 is drawn into the chamber 20 in which the water and the adjuvant mix to produce a dilute solution of adjuvant in the chosen dilution ratio. At the end of the ascent of the rod 36, the lower seal forming the valve 41 closes, while the upper seal forming the valve 37 opens, thus allowing a new dose of adjuvant to enter the metering chamber 45 of the pump. . The pump 15 is thus primed, as illustrated in FIG. 7.
Après amorçage de la pompe 15, l'utilisateur appuie de nouveau sur la tête 64 du bouchon 59. Sous l'effet de la descente de la tige formant piston 36, la solution diluée d'adjuvant présente dans la chambre de mélange 20 est alors refoulée et envoyée vers le dispositif de pul- vérisation 16 via le conduit 30 par suite de l'ouverture du clapet 31 sous l'effet de la pression de la solution refoulée. On obtient alors, par le dispositif de pulvérisation 16, une éjection de solution diluée d'adjuvant, comme illustré à la figure 8.After priming of the pump 15, the user presses again on the head 64 of the plug 59. Under the effect of the descent of the piston rod 36, the diluted adjuvant solution present in the mixing chamber 20 is then discharged and sent to the spraying device 16 via the conduit 30 following the opening of the valve 31 under the effect of the pressure of the discharged solution. There is then obtained, by the spraying device 16, an ejection of dilute adjuvant solution, as illustrated in FIG. 8.
Dès que l'utilisateur relâche la tête 64 du bouchon 59, la pompe 15, sous l'effet du ressort 23, se réamorce comme illustré à la figure 9. As soon as the user releases the head 64 from the plug 59, the pump 15, under the effect of the spring 23, is re-primed as illustrated in FIG. 9.
