Description
La présente invention concerne un fer à repasser, notamment à vapeur, comportant un réservoir d'eau, un réservoir contenant un adjuvant 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'adjuvant 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 steam, comprising a water tank, a tank containing a textile additive, and a pump comprising a mixing chamber and clean, on the one hand, to draw a dose of water from the tank into the mixing chamber water as well as the adjuvant from the adjuvant tank via a tap for dosing the adjuvant, so as to produce a solution in the mixing chamber diluted adjuvant, and secondly, to send this solution to a spray 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 faux plis.We know that with such an iron, spraying on the linen of a diluted active product used to facilitate ironing while improving glide and erasing fakes folds.
Dans un fer à repasser connu de ce genre, décrit par exemple dans la demande de brevet FR 2 771 424, 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, described for example in
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. The object of the invention is in particular to remedy these disadvantages and to make an iron, of the type set out above, in which the pumping members and of adjuvant dosage are grouped together, this in order to simplify their implantation in iron.
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 l'adjuvant.In an iron according to the invention, the pump is of the type with piston moving in a body and delimiting in the lower part of the body the mixing chamber which opens out in the water tank via a non-return valve, and this pump also acts as a metering tap adjuvant.
La pompe et le robinet de dosage de l'adjuvant sont ainsi groupés en un ensemble unitaire compact. De surcroít, 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 être réalisée sous la forme d'une petite pompe, donc à faible encombrement dans le fer.The adjuvant dosing valve and pump are thus grouped into a compact unitary assembly. In addition, the pump alone advantageously fills a double function, namely that of pumping to vacuum the water and the adjuvant, and that of the dosage of the adjuvant intended to be mixed with the aspirated water, thus constituting in itself a real dosing pump for a mixture of water and textile additive. Such a metering pump can be realized in the form of a small pump, therefore with low footprint 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 manière à 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 includes two movable open-close moving parts, respectively called upper and lower, mounted in the pump body, delimiting between them a dosing chamber, and controlled respectively by first and second actuation means related to piston, said upper and lower members being movable between a rest position in which the organ upper is open, while the lower organ is closed, so as to allow the passage of a dose of adjuvant from the adjuvant tank to the dosage, and a working position in which the organ superior closes under the action of the first means actuation, while the lower organ opens under the action of the second actuation means, so allow the adjuvant dose to pass from the dosing chamber to the mixing chamber.
Les deux organes mobiles d'ouverture-fermeture, délimitant 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 parts, delimiting between them the dosing chamber, thus play together the role of a valve integrated into the pump itself said and adapted to dose the adjuvant intended to be mixed water sucked 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 tank is an integral part of the pump. Thus, the dosing pump and the adjuvant tank advantageously constitute a qualified unitary unit particularly compact.

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 Figure 1, the iron is
additionally equipped with a unitary assembly, designated by the

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.
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 de 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
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 shown in Figures 2, 7, 8 and 9,
the
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 étanche,
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
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 constitué
présentement par une bille 31 coopérant avec un siège

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
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
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'environ
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. For example, the adjuvant being a concentrated product, the
Selon un mode de réalisation illustré aux 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

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.According to an embodiment illustrated in the figures
2, 7, 8 and 9, the

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'autre
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
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 titre 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

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 Figure 3, the
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 indémontables
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.Opposite Figures 2 and 7, the
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
Ainsi, le remplissage du réservoir d'adjuvant 12
s'effectue d'une manière aisée par l'utilisateur. Celui-ci
lève légèrement le bouchon 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
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 inférieur
formant clapet 41, comme on le voit bien à la figure
7.When filling the
Après remplissage du réservoir d'adjuvant 12,
l'utilisateur repousse le bouchon 59 pour fermer l'ouverture
65 dans laquelle s'adapte exactement l'extrémité supérieure
67 de la tige 36, comme illustré à la figure 7.After filling the
Il convient de noter que le fait de rendre imperdable
le bouchon 59 du réservoir d'adjuvant 12 est particulièrement
plaisant pour l'utilisateur.It should be noted that making captive
the
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
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. There are shown at 69 in Figures 2, 7, 8 and 9
a flexible bellows which is interposed between the upper wall
of the
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.The
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
Dans cet exemple, figure 1, le réservoir d'adjuvant
12 est en quasi-totalité en saillie de la partie antérieure
du fer et est transparent, rendant ainsi visible
le niveau d'adjuvant.In this example, Figure 1, the
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 ressort
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 une 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 the
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 pulvérisation
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
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
