Description

La présente invention se rapporte à un appareil pour repasser ou défroisser le linge et plus particulièrement à un appareil de ce type comportant un dispositif pour répandre un additif sur le linge.The present invention relates to an apparatus for ironing or degreasing the laundry and more particularly to an apparatus of this type comprising a device for spreading an additive on the laundry.

Il est connu du document WO98/06890 un appareil à vapeur pour défroisser le linge comportant un réservoir d'additif qui est traversé par un flux de vapeur, le réservoir renfermant des plantes désinfectantes ou un parfum dont la substance active est transportée avec la vapeur sur le linge de façon à désinfecter ou parfumer ce dernier.It is known from the document WO98 / 06890 a steaming appliance for steaming laundry comprising an additive tank which is traversed by a stream of steam, the tank containing disinfectant plants or a perfume whose active substance is transported with the steam on the laundry so as to disinfect or perfume this last.

EP-A-1 449 911 décrit une composition aqueuse comportant des microcapsules renfermant des composants actifs qui facilitent le repassage du textile traité. EP-A-1 449 911 discloses an aqueous composition comprising microcapsules containing active components that facilitate the ironing of the treated textile.

EP-A-1 582 620 , qui est un document relevant selon l'article 54(3) CBE, décrit un appareil pour repasser comportant un réservoir d'additif avec des microcapsules dissoutes dans un liquide. EP-A-1,582,620 , which is a relevant document under Article 54 (3) EPC, describes an ironing appliance with an additive tank with microcapsules dissolved in a liquid.

US-A-5 966 831 décrit un substrat avec des microcapsules, ce substrat est destiné d'être utiliser dans un tambour d'un sèche-linge. US-A-5,966,831 describes a substrate with microcapsules, this substrate is intended to be used in a drum of a dryer.

US-B-6 351 901 peut être considéré comme le document de l'état de la technique le plus proche de l'invention. Ce document divulgue un fer à repasser comportant un réservoir d'additif muni d'une mèche capillaire imprégnée d'additif et
balayée par un flux de vapeur sortant d'un conduit de sorte que l'additif est transporté par la vapeur en dehors du fer. US-B-6,351,901 can be considered as the document of the state of the art closest to the invention. This document discloses an iron with an additive reservoir provided with a hair wick impregnated with additive and
swept by a stream of vapor exiting a conduit so that the additive is transported by steam outside the iron.

Un tel dispositif pour répandre un additif présente cependant l'inconvénient de posséder un réservoir d'additif qui est largement ouvert à la circulation d'air de sorte que l'additif se diffuse en dehors de l'appareil même lorsque ce dernier n'est pas utilisé. Il s'ensuit un épuisement rapide de l'efficacité de l'additif et une diffusion excessive de l'additif à l'endroit où l'appareil est stocké, ce qui peut générer des nuisances notamment lorsque l'additif est un parfum.Such a device for spreading an additive, however, has the disadvantage of having an additive reservoir which is largely open to the flow of air so that the additive diffuses out of the apparatus even when the latter is not not used. It follows a rapid depletion of the effectiveness of the additive and excessive diffusion of the additive at the location where the device is stored, which can generate nuisance especially when the additive is a fragrance.

Aussi, un but de la présente invention est de remédier à ces inconvénients.Also, an object of the present invention is to overcome these disadvantages.

A cet effet, l'invention a pour objet un appareil pour repasser ou défroisser le linge comportant un dispositif pour répandre un additif sur le linge comprenant un réservoir d'additif, caractérisé en ce que le réservoir d'additif comprend un substrat qui supporte des microcapsules et en ce que les microcapsules du substrat sont emportées progressivement par un flux de fluide émis par le dispositif pour répandre l'additif sur le linge, le flux transportant les microcapsules en dehors de l'appareil.For this purpose, the subject of the invention is an apparatus for ironing or degreasing laundry comprising a device for spreading an additive on the laundry comprising a additive reservoir, characterized in that the additive reservoir comprises a substrate which supports microcapsules and in that the microcapsules of the substrate are progressively carried away by a flow of fluid emitted by the device for spreading the additive on the laundry, the flow carrying the microcapsules outside the device.

Une telle caractéristique permet d'obtenir un réservoir de microcapsules sous forme solide qui peut être aisément manipulé ou transporté et qui présente l'avantage d'être facilement adaptable à de nombreux appareils.Such a characteristic makes it possible to obtain a microcapsule reservoir in solid form which can be easily handled or transported and which has the advantage of being easily adaptable to many devices.

La membrane des microcapsules est préférentiellement réalisée dans un matériau chimiquement compatible avec les matériaux du dispositif utilisé pour répandre l'additif. Par matériau chimiquement compatible, on entend un matériau qui ne dégrade pas de façon perceptible les matériaux du dispositif d'épandage de l'additif sur la durée de vie de l'appareil.The membrane of the microcapsules is preferably made of a material that is chemically compatible with the materials of the device used for spread the additive. By chemically compatible material is meant a material which does not noticeably degrade the materials of the device for spreading the additive over the lifetime of the device.

La microencapsulation de l'additif présente l'avantage de supprimer le contact direct entre l'additif et les éléments du dispositif permettant de répandre l'additif, ce qui permet de réduire les problèmes d'agression chimique ou de colmatage liés à la nature de l'additif.The microencapsulation of the additive has the advantage of eliminating the direct contact between the additive and the elements of the device for spreading the additive, which makes it possible to reduce the problems of chemical aggression or clogging related to the nature of the additive. the additive.

Dans le cas de l'utilisation d'un additif sensible à l'élévation de la température, tel que des huiles essentielles, la microencapsulation présente également l'avantage d'éviter que l'additif ne perde de son effet lorsque le réservoir d'additif est soumis à des températures élevées.In the case of the use of an additive sensitive to the rise in temperature, such as essential oils, microencapsulation also has the advantage of preventing the additive from losing its effect when the reservoir of additive is subjected to high temperatures.

Enfin, la microencapsulation de l'additif présente l'avantage d'éviter la diffusion dans l'atmosphère de l'additif lors de son stockage ou lorsqu'il est répandu au moyen d'un dispositif de pulvérisation. On évite ainsi que l'utilisateur n'inhale de l'additif.Finally, the microencapsulation of the additive has the advantage of avoiding diffusion into the atmosphere of the additive during storage or when it is spread by means of a spraying device. This prevents the user from inhaling the additive.

Selon une autre caractéristique de l'appareil selon l'invention, les microcapsules sont collées ou imprégnées sur le substrat.According to another characteristic of the apparatus according to the invention, the microcapsules are bonded or impregnated on the substrate.

Selon une autre caractéristique de l'appareil selon l'invention, l'appareil est un appareil à vapeur et le dispositif pour répandre l'additif est un dispositif de pulvérisation utilisant la force motrice de la vapeur.According to another characteristic of the apparatus according to the invention, the apparatus is a steam apparatus and the device for spreading the additive is a spraying device using the driving force of the steam.

Une telle caractéristique présente l'avantage de permettre l'obtention d'un pulvérisateur puissant à faible coût, l'encapsulation de l'additif permettant de limiter très fortement l'émission dans l'atmosphère de l'additif inhérent à la pulvérisation.Such a characteristic has the advantage of making it possible to obtain a powerful low-cost sprayer, the encapsulation of the additive making it possible to very strongly limit the emission into the atmosphere of the additive inherent in the spray.

Selon une autre caractéristique de l'appareil selon l'invention, le substrat est un textile imprégné de microcapsules et le dispositif de pulvérisation comprend des moyens d'envoi d'un flux de vapeur au travers du textile.According to another characteristic of the apparatus according to the invention, the substrate is a textile impregnated with microcapsules and the spraying device comprises means for sending a stream of vapor through the textile.

Selon une autre caractéristique de l'appareil selon l'invention, le substrat est une grille sur laquelle sont collées des microcapsules et le dispositif de pulvérisation comprend des moyens d'envoi d'un flux de vapeur au travers de la grille.According to another characteristic of the apparatus according to the invention, the substrate is a grid on which microcapsules are glued and the spray device comprises means for sending a stream of vapor through the grid.

Selon une autre caractéristique de l'appareil selon l'invention, l'additif contenu dans les microcapsules comprend un parfum ou un principe actif anti-odeur, tel que de l'acide undécylénique.According to another characteristic of the apparatus according to the invention, the additive contained in the microcapsules comprises a fragrance or an anti-odor active principle, such as undecylenic acid.

Selon une autre caractéristique de l'appareil selon l'invention, le réservoir est amovible du fer.According to another characteristic of the apparatus according to the invention, the reservoir is removable from the iron.

Une telle caractéristique permet de remplir facilement le réservoir ou de l'échanger rapidement contre un autre.Such a feature makes it easy to fill the tank or exchange it quickly for another.

L'invention concerne également un réservoir amovible destiné à équiper un appareil pour repasser ou défroisser le linge tel que précédemment décrit, caractérisé en ce qu'il contient au moins un additif conditionné sous forme de microcapsules, lesdites microcapsules étant supportées par un substrat.The invention also relates to a removable reservoir for equipping an apparatus for ironing or degreasing the laundry as described above, characterized in that it contains at least one additive packaged in the form of microcapsules, said microcapsules being supported by a substrate.

Selon une autre caractéristique du réservoir selon l'invention, les microcapsules sont collées ou imprégnées sur le substrat.According to another characteristic of the reservoir according to the invention, the microcapsules are bonded or impregnated on the substrate.

Selon une autre caractéristique du réservoir selon l'invention, le substrat est un textile imprégné de microcapsules.According to another characteristic of the reservoir according to the invention, the substrate is a textile impregnated with microcapsules.

Selon encore une autre caractéristique du réservoir selon l'invention, le substrat est une grille sur laquelle des microcapsules sont collées.According to yet another characteristic of the reservoir according to the invention, the substrate is a grid on which microcapsules are glued.

On comprendra mieux les buts, aspects et avantages de la présente invention, d'après la description donnée ci-après de modes particuliers de réalisation de l'invention présentés à titre d'exemples non limitatifs, en se référant aux dessins annexés dans lesquels :

  • La figure 2 représente une vue de dessous de l'appareil de la figure 1 équipé du réservoir d'additif selon l'invention ;
  • La figure 3 est une vue similaire à la figure 2 illustrant le sens de montage et de démontage du réservoir.
The aims, aspects and advantages of the present invention will be better understood from the description given below of particular embodiments of the invention presented by way of non-limiting examples, with reference to the appended drawings in which:
  • The figure 1 is a side view of a steamer apparatus provided with an additive reservoir according to a particular embodiment of the invention;
  • The figure 2 represents a bottom view of the device from the figure 1 equipped with the additive tank according to the invention;
  • The figure 3 is a view similar to the figure 2 illustrating the direction of assembly and disassembly of the tank.

Seuls les éléments nécessaires à la compréhension de l'invention ont été représentés. Pour faciliter la lecture des dessins les mêmes éléments portent les mêmes références d'une figure à l'autre.Only the elements necessary for the understanding of the invention have been represented. To facilitate the reading of the drawings the same elements the same references from one figure to another.

Les figures 1 à 3 représentent un mode de réalisation particulier de l'invention dans lequel l'invention est appliquée à un appareil pouvant être utilisé pour défroisser les textiles par la seule émission de vapeur, c'est-à-dire sans qu'il y ait contact d'une semelle chaude avec le textile, par exemple pour améliorer l'aspect de rideaux fragiles.The Figures 1 to 3 represent a particular embodiment of the invention in which the invention is applied to an apparatus that can be used for de-wrinkling textiles by the sole emission of steam, that is to say without there being contact of a warm sole with textile, for example to improve the appearance of fragile curtains.

L'appareil illustré sur ces figures est semblable à celui décrit dans la demande de brevet FR 2 822 480 et comprend classiquement un corps 1 en matière plastique formant une poignée et une semelle métallique, non visible sur les figures, en relation thermique avec un corps chauffant dans lequel une chambre de vaporisation est ménagée. Un réservoir d'eau amovible, non représenté, est logé à l'intérieur de la poignée. L'eau est propulsée dans la chambre de vaporisation par une pompe manuelle actionnée par pression sur une commande 4, la vapeur s'échappant par des orifices 2 répartis sur la semelle.The apparatus illustrated in these figures is similar to that described in the patent application FR 2 822 480 and conventionally comprises a plastic body 1 forming a handle and a metal sole, not visible in the figures, in thermal relation with a heating body in which a vaporization chamber is formed. A removable water tank, not shown, is housed inside the handle. The water is propelled into the vaporization chamber by a manual pump actuated by pressure on a control 4, the steam escaping through orifices 2 distributed on the sole.

La semelle est recouverte par un accessoire 10 en matière plastique formant une enveloppe entourant la semelle du fer et empêchant que la semelle chaude du fer ne vienne en contact direct avec le textile. L'accessoire 10 comporte un passage 11 dont la surface se met en correspondance avec les orifices de sortie 2 de vapeur du fer et présente une nervure 12 supportant une rangée de touffes de poils constituant une brosse 13.The sole is covered by a plastic accessory 10 forming an envelope surrounding the sole of the iron and preventing the hot sole of the iron comes into direct contact with the textile. The accessory 10 has a passage 11 whose surface is in correspondence with the iron vapor outlet openings 2 and has a rib 12 supporting a row of tufts of bristles constituting a brush 13.

L'accessoire 10 est fixé de façon amovible sur le corps 1 du fer, de manière connue en soi, par exemple par encliquetage. A l'intérieur de l'accessoire, autour du passage 11, un bourrelet portant un joint assure l'étanchéité à la vapeur quand l'accessoire est monté sur le fer.The accessory 10 is removably attached to the body 1 of the iron, in a manner known per se, for example by snapping. Inside the accessory, around the passage 11, a bead carrying a seal ensures vapor tightness when the accessory is mounted on the iron.

Plus particulièrement selon l'invention, le fer reçoit un réservoir d'additif 20 monté de manière amovible en regard des orifices 2 de sortie de vapeur de la semelle, le réservoir 20 comportant un cadre 21 supportant un substrat 22 perméable à la vapeur sur lequel sont collées ou imprégnées des microcapsules d'additifs.More particularly according to the invention, the iron receives an additive tank 20 removably mounted opposite the outlet openings 2 of steam of the sole, the tank 20 having a frame 21 supporting a vapor-permeable substrate 22 on which are glued or impregnated microcapsules additives.

Le cadre support 21 s'engage latéralement dans des rainures 14 réalisées sur le bord intérieur de la nervure 12 supportant la brosse 13 et est immobilisé en position par des bossages élastiques. Le substrat 22 est préférentiellement placé à une distance de l'ordre de 5 mm des orifices 2 de sorties pour obtenir une répartition de la vapeur sur tout le substrat 22.The support frame 21 engages laterally in grooves 14 made on the inner edge of the rib 12 supporting the brush 13 and is immobilized in position by elastic bosses. The substrate 22 is preferably placed at a distance of about 5 mm from the outlet orifices 2 to obtain a distribution of the vapor over the entire substrate 22.

A titre d'exemple, le substrat 22 est préférentiellement constitué par un tissu imbibé de microcapsules ou par une grille métallique sur laquelle les microcapsules sont collées. Le substrat 22 peut ainsi être constitué par un treillis formé de brins de laine supporté par le cadre support 21 et imbibé d'une solution de microcapsules d'additif.For example, the substrate 22 is preferably constituted by a tissue soaked with microcapsules or by a metal gate on which the microcapsules are glued. The substrate 22 may thus be constituted by a lattice formed of wool strands supported by the support frame 21 and impregnated with a solution of additive microcapsules.

Les microcapsules sont préférentiellement constituées par des capsules à parois polymériques d'un diamètre de quelques micromètres et sont préparées suivant un procédé connu en soi, par exemple selon l'un des procédés décrits dans les brevets français FR 1 334 918 et FR 2 548 046 .The microcapsules are preferably constituted by capsules with polymer walls having a diameter of a few micrometers and are prepared according to a method known per se, for example according to one of the processes described in French patents. FR 1 334 918 and FR 2 548 046 .

Les membranes des microcapsules seront, par exemple, réalisées en mélamine-formaldéhyde. L'additif contenu dans les microcapsules est avantageusement choisi parmi les parfums ou les principes actifs anti-bactérien ou anti-odeur connus, tel que de l'acide undécylénique (CH2=CH(CH2)8COOH).The membranes of the microcapsules will, for example, be made of melamine-formaldehyde. The additive contained in the microcapsules is advantageously chosen from known anti-bacterial or anti-odor fragrances or active ingredients, such as undecylenic acid (CH 2 = CH (CH 2 ) 8 COOH).

Le pouvoir adhésif de la colle ou du liquide d'imprégnation est avantageusement choisi de telle sorte que les microcapsules restent attachées au substrat 22 lorsque ce dernier est à la température ambiante mais se détachent du substrat 22 lorsqu'elles sont soumises à un flux de vapeur.The adhesive power of the adhesive or the impregnating liquid is advantageously chosen so that the microcapsules remain attached to the substrate 22 when the latter is at ambient temperature but become detached from the substrate 22 when subjected to a stream of vapor .

Avec cet appareil, lorsque l'utilisateur souhaite traiter son linge avec un additif, il engage le réservoir d'additif 20 sur les rainures 14 de manière à ce que le substrat 22 vienne en regard des orifices 2 de sorties de vapeur. L'utilisateur presse ensuite la commande 4 pour générer un flux de vapeur qui est envoyé par les orifices 2 de sorties de vapeur au travers du substrat 22. Les contraintes thermique et hygrométrique générées par le flux de vapeur provoquent alors le détachement progressif des microcapsules du substrat 22 et les microcapsules ainsi libérées sont transportées par le flux de vapeur jusqu'au textile à traiter.With this apparatus, when the user wishes to treat his laundry with an additive, he engages the additive reservoir 20 on the grooves 14 so that the substrate 22 comes opposite the orifices 2 of steam outlets. The user then presses the control 4 to generate a stream of vapor which is sent through the vapor outlet orifices 2 through the substrate 22. The thermal and hygrometric stresses generated by the vapor flow then cause the progressive detachment of the microcapsules from the substrate 22 and the microcapsules thus released are transported by the steam flow to the textile to be treated.

Le réservoir d'additif 20 ainsi constitué peut être utilisé à plusieurs reprises par l'utilisateur, jusqu'à épuisement des microcapsules contenues dans le substrat 22. Un tel réservoir d'additif présente l'avantage de pouvoir être stocké sans qu'il y ait des émanations importantes de l'additif. Le réservoir d'additif pourra donc être stocké longtemps sans qu'il y ait un épuisement important de l'efficacité de l'additif et sans problème de pollution de l'environnement. La microencapsultion de l'additif présente également l'avantage d'éviter le colmatage du substrat que pourrait provoquer la nature de l'additif et de protéger thermiquement l'additif lorsqu'il est balayé par le flux de vapeur, ce qui permet ainsi de conserver son intégrité.The additive reservoir 20 thus formed can be used several times by the user, until the microcapsules contained in the substrate 22. Such an additive reservoir has the advantage of being able to be stored without there being significant emanations of the additive. The additive reservoir can therefore be stored for a long time without there being a significant depletion of the effectiveness of the additive and without environmental pollution problem. The microencapsulation of the additive also has the advantage of avoiding the clogging of the substrate that could cause the nature of the additive and thermally protect the additive when it is swept by the vapor flow, which allows to maintain its integrity.
