Description
L'invention se rapporte aux centrales de repassage à vapeur comprenant un fer à repasser équipé d'une semelle chauffante présentant des trous de sortie de vapeur, un générateur de vapeur communiquant avec lesdits trous de vapeur, un réservoir d'eau indépendant, une pompe électrique comportant un carter et un organe mobile d'entraînement de l'eau entre un orifice d'admission relié audit réservoir d'eau et un orifice de refoulement relié audit générateur de vapeur, ainsi qu'un moyen de traitement de l'eau destiné notamment à la déminéraliser.The invention relates to steam ironing plants comprising an iron equipped with a heating soleplate having steam outlet holes, a steam generator communicating with said steam holes, an independent water tank, a pump electric comprising a casing and a movable member for driving the water between an inlet orifice connected to said water tank and a discharge orifice connected to said steam generator, as well as a water treatment means intended in particular to demineralize it.
Dans les centrales de repassage connues à ce jour, on utilise des pompes à déplacement forcé, par exemple, des pompes péristaltiques ou des pompes du type électromagnétique à noyau plongeur qui comportent des clapets bi-directionnels interdisant toute libre circulation d'eau à travers le carter lorsqu'elles ne fonctionnent pas. Par conséquent, afin d'éviter les inconvénients dus à une surpression dans le générateur de vapeur lorsque les trous de vapeur s'entartrent, il est nécessaire d'installer sur les canalisations des sécurités de délestage, sécurité du type clapet, soupape tarée, qui sont généralement onéreuses et difficiles à contrôler. En outre, ces pompes arrivent à se désamorcer lorsque le réservoir d'eau se vide et il est impossible de les réamorcer tant qu'il subsiste une contre-pression dans le générateur de vapeur.In ironing plants known to date, forced displacement pumps are used, for example, peristaltic pumps or pumps of the electromagnetic type with plunger core which include bi-directional valves preventing any free circulation of water through the crankcase when they are not working. Consequently, in order to avoid the drawbacks due to an overpressure in the steam generator when the steam holes scale up, it is necessary to install load-shedding safety devices, safety of the valve type, calibrated valve, which are generally expensive and difficult to control. In addition, these pumps manage to prime when the water tank is empty and it is impossible to prime them as long as there is back pressure. in the steam generator.
L'invention a notamment pour but d'éliminer ces inconvénients, et de réduire le coût de fabrication des centrales de repassage.The object of the invention is in particular to eliminate these drawbacks and to reduce the cost of manufacturing ironing plants.
Selon l'invention la pompe présente une libre circulation d'eau entre les deux orifices d'admission et de refoulement au moins lorsque l'organe d'entraînement est au repos.According to the invention, the pump has a free circulation of water between the two inlet and outlet ports at least when the drive member is at rest.
Selon une caractéristique avantageuse de l'invention, la pompe est du type centrifuge et l'organe mobile est constitué par une roue à aubes solidaire d'un arbre d'entraînement et montée rotative dans le carter avec au moins un jeu périphérique.According to an advantageous characteristic of the invention, the pump is of the centrifugal type and the movable member consists of an impeller secured to a drive shaft and rotatably mounted in the casing with at least one peripheral clearance.
Ainsi, grâce à l'utilisation d'une telle pompe, lorsque l'organe d'entraînement est au repos, l'eau peut circuler librement dans le carter puisqu'elle ne rencontre aucun obstacle, du fait notamment de l'absence d'étanchéité entre carter et organe mobile et de l'absence de clapet. Cette libre circulation permet donc à l'eau de retourner vers le réservoir d'eau froide soit par gravité, soit sous l'action d'une éventuelle surpression au niveau du générateur de vapeur.Thus, thanks to the use of such a pump, when the drive member is at rest, the water can circulate freely in the casing since it does not encounter any obstacle, due in particular to the absence of tightness between casing and movable member and the absence of a valve. This free circulation therefore allows the water to return to the cold water tank either by gravity or under the action of a possible overpressure at the level of the steam generator.
Selon une autre caractéristique de l'invention, le moyen de traitement de l'eau est monté dans la canalisation entre le générateur de vapeur et ladite pompe.According to another characteristic of the invention, the water treatment means is mounted in the pipe between the steam generator and said pump.
Ainsi grâce à cette disposition, on peut placer le moyen de traitement de l'eau dans le fer à repasser, ce qui était rendu impossible dans les centrales antérieures puisqu'il était nécessaire de déminéraliser l'eau en amont de la pompe afin d'éviter l'entartrage des éléments métalliques de pompe tels que ressorts et clapets.Thus thanks to this arrangement, it is possible to place the water treatment means in the iron, which was made impossible in earlier plants since it was necessary to demineralize the water upstream of the pump in order to avoid scaling of metallic pump elements such as springs and valves.
Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins annexés dans lesquels :
la figure 1 représente schématiquement et en coupe partielle une centrale de repassage selon l'invention comportant un fer à repasser, un réservoir d'eau froide associé à une pompe électrique et posé horizontalement, la figure 2 représente en coupe partielle, à échelle agrandie, une pompe à auto-amorçage selon l'invention immergée dans un réservoir d'eau ; la figure 3 représente à plus petite échelle une variante de réalisation d'un réservoir d'eau associé à une pompe selon l'invention et accroché verticalement.The characteristics and advantages of the invention will emerge moreover from the description which follows, by way of example, with reference to the appended drawings in which:
FIG. 1 shows schematically and in partial section an ironing plant according to the invention comprising an iron, a cold water tank associated with an electric pump and placed horizontally, FIG. 2 represents in partial section, on an enlarged scale, a self-priming pump according to the invention immersed in a water tank; Figure 3 shows on a smaller scale an alternative embodiment of a water tank associated with a pump according to the invention and hung vertically.
Comme représenté à la figure 1, la centrale de repassage à vapeur comprend un fer à repasser 1 équipé d'une semelle chauffante 2 présentant des trous 3 de sortie de vapeur, un générateur de vapeur 4 communiquant avec lesdits trous de vapeur 3, un réservoir d'eau indépendant 5 dont le boîtier 6 comporte une ouverture de remplissage 7 fermé par un bouchon à évent 8 schématisé en traits interrompus, une pompe à moteur électrique 9 comportant un carter 10 et un organe interne mobile 11 d'entraînement de l'eau entre un orifice d'admission 12 relié audit réservoir et un orifice de refoulement 13 relié, par une canalisation 14 au générateur de vapeur 4, ainsi qu'un moyen 15 de traitement de l'eau destiné notamment à la déminéraliser.As shown in FIG. 1, the steam ironing center comprises an iron 1 equipped with a
Dans l'exemple de réalisation décrit à titre d'exemple non limitatif, le générateur de vapeur 4 est intégré au fer à repasser 1 et est équipé, de façon connue en soi, d'un dispositif d'écoulement d'eau goutte à goutte comprenant une petite chambre 16 dont l'orifice de sortie 17 est muni d'un pointeau réglable 18 et dont l'orifice d'entrée est relié par la canalisation 14 au moyen 15 de traitement de l'eau. Bien entendu, le générateur de vapeur 4 pourrait être indépendant du fer et installé sur la canalisation 14 ou dans le boîtier 6 du réservoir modifié à cet effet.In the embodiment described by way of nonlimiting example, the
Selon l'invention la pompe 9 présente une libre circulation d'eau entre les deux orifices d'admission 12 et de refoulement 13 au moins lorsque l'organe d'entraînement 11 est au repos. Selon un exemple de réalisation préférée la pompe 9 est du type centrifuge et l'organe mobile 11 est constitué par une roue à aubes solidaire d'un arbre d'entraînement 19 et montée rotative dans le carter 10 avec au moins un jeu périphérique (référencé par e sur la figure 1), ledit carter 10 ayant l'orifice d'admission 12 agencée axialement, et l'orifice de refoulement 13 agencé à sa périphérie. Outre les pompes centrifuges, on peut utiliser comme pompe à libre circulation d'eau des pompes connues en soi dans lesquelles l'organe d'entraînement, palettes ou galets, vient frotter contre le carter sous l'effet de la force centrifuge lorsqu'il est en mouvement, et ménage un jeu lorsqu'il est au repos sous l'effet d'un rappel élastique.According to the invention the
Comme on le voit sur la figure 1, la pompe centrifuge 9 utilisée est du type vertical à carter immergé et est montée à cet effet dans un puits 20 formé dans le boîtier 6 du réservoir 5 avec son entrée d'aspiration 12 tournée vers le fond dudit réservoir. Le carter 10 est situé à proximité du fond du réservoir et est monté de façon étanche dans le puits 20 au moyen d'un joint périphérique 20'. Ainsi la roue à aubes 11 est toujours immergée lorsque le réservoir est rempli d'eau.As seen in Figure 1, the
Selon une variante de réalisation représentée à la figure 2 la pompe 9 est auto-amorçable, et le carter 10 comporte à cet effet une ouverture supplémentaire 21 de dégazage agencée sur la paroi supérieure du carter traversée par l'arbre moteur 19. Ainsi, lorsque l'utilisateur doit procéder à un remplissage en eau du réservoir 5, l'air s'étant accumulé dans le carter 10, peut s'échapper sous la pression de l'eau par l'ouverture 21, permettant à la roue à aubes 11 d'être de nouveau immergée.According to an alternative embodiment shown in FIG. 2, the
Les avantages liés à l'utilisation d'une pompe à libre circulation d'eau du type par exemple centrifuge sont notamment : réduction du coût de fabrication de la centrale ; fiabilité de la pompe du fait de l'absence de clapet et de ressort ; fonctionnement pratiquement à vide de la pompe ; sécurité assurée en cas de surpression de vapeur dans la canalisation ; débit régulier de l'eau en sortie de la pompe sans pulsation nuisible pour le pointeau 18 et la chambre 4, comme dans le cas d'une pompe électro-magnétique.The advantages linked to the use of a free circulation pump of the centrifugal type, for example, are: reduction of the manufacturing cost of the power station; reliability of the pump due to the absence of valve and spring; practically empty operation of the pump; safety ensured in the event of overpressure of vapor in the pipeline; regular flow of water at the outlet of the pump without harmful pulsation for the needle 18 and the
Selon une autre caractéristique de l'invention, le moyen 15 de traitement de l'eau est monté dans la canalisation 14 entre le générateur de vapeur 4 et la pompe 9, et comporte une çassette 13 comprenant au moins un filtre 22 agencé à la sortie d'eau et un produit de déminéralisation de l'eau telle qu'une résine. De préférence, la cassette 13 comporte deux filtres, le filtre 22 et un filtre 23 agencé à l'entrée de la cassette et destiné à retenir les impuretés contenues dans l'eau du réservoir. Dans un premier mode de réalisation, schématisé à la figure 1, cette cassette 15 est installée dans le boîtier 6. Dans un second mode de réalisation (figure 1), la cassette 15, (représentée en traits interrompus), est agencée dans ledit fer à repasser 1 et est montée amovible, de manière connue en soi, pour permettre son échange lorsque la résine est saturée.
Cet agencement permet, outre de placer la cassette dans le fer pour une meilleur vision de son état de saturation, d'installer la pompe 9 le plus près possible du fond du réservoir 5 de façon à faciliter son amorçage et la mise en pression du circuit d'eau.According to another characteristic of the invention, the
This arrangement allows, in addition to placing the cassette in the iron for a better view of its state of saturation, to install the
En outre, grâce à la combinaison particulière d'une pompe à libre circulation d'eau et de la cassette disposée en aval de la pompe, il est possible à ce jour d'équiper le fer d'un dispositif de pulvérisation d'eau froide comportant une pompe 24 à piston 24' dont l'orifice de refoulement est branchée à une buse de vaporisation 25 située à l'avant du fer et dont l'orifice d'admission 26 est reliée à la canalisation d'eau 14 au moyen d'un raccord 27 solidaire de la petite chambre 16. Ce raccord 27 et la chambre 16 font partie d'une même pièce moulée afin de réduire le coût de fabrication.In addition, thanks to the special combination of a pump with free circulation of water and the cassette placed downstream of the pump, it is possible to date to equip the iron with a device for spraying cold water. comprising a piston pump 24 '24', the discharge orifice of which is connected to a
Ainsi, la Demanderesse a vaincu un préjugé qui lui interdisait d'équiper d'une buse de pulvérisation les fers à repasser connus, comportant une pompe dite à circulation d'eau "forcée" telle qu'une pompe électromagnétique ou péristaltique. En effet, la pompe de vaporisation à piston ne peut pas créer de dépression suffisante dans la canalisation 14 pour, à la fois, actionner les clapets de la pompe à circulation d'eau "forcée" et vaincre la perte de charge de la cassette de déminéralisation afin de pomper l'eau du réservoir. Par contre, grâce à l'invention, la pompe de vaporisation 24, par action répétée sur le piston 24', aspire aisément l'eau du réservoir 5 à travers la cassette 15 et le jeu e existant entre le carter 10 et l'organe 11 de la pompe 9. En outre, la cassette 13 du fait de son agencement permet de diminuer la pression de l'eau dans la canalisation et d'obtenir une régularisation du débit d'eau particulièrement avantageuse et efficace pour le réglage du débit d'eau dans le générateur de vapeur au niveau de la petite chambre 16 et du pointeau 18.Thus, the Applicant has overcome a prejudice which prevented it from equipping known irons with a spray nozzle, comprising a so-called "forced" water circulation pump such as an electromagnetic or peristaltic pump. Indeed, the piston spray pump cannot create sufficient vacuum in the
De plus, l'utilisation d'une pompe centrifuge à carter immergé, permet d'utiliser la centrale de repassage soit comme illustrée à la figure 1 avec le réservoir d'eau en position horizontale, soit comme illustrée à la figure 3 avec le réservoir d'eau 5 suspendu verticalement par un crochet 28 à un support 29 solidaire par exemple du piètement d'une table à repasser (non représentée).In addition, the use of a centrifugal pump with submerged casing makes it possible to use the ironing center either as illustrated in FIG. 1 with the water tank in horizontal position, or as illustrated in FIG. 3 with the tank. 5 suspended vertically by a
Dans le cas où, le réservoir d'eau 5 est en charge, c'est à dire, situé à un niveau supérieur au plan de travail où repose le fer, la canalisation d'eau 14 reliée au générateur de vapeur 4 comporte un clapet 30 dont l'ouverture autorisant le passage de l'eau est commandée par un élément thermique 31 tel qu'un bilame en liaison avec la semelle chauffante 2. Ainsi cet élément thermique libère le passage de l'eau seulement quand le fer est chaud.In the case where the
