Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine des fers à repasser comprenant une surface de repassage destinée à venir au contact du linge et un boîtier muni d'une poignée de préhension dans lequel le boîtier comprend un dispositif d'éclairage comportant une source lumineuse agencée pour émettre de la lumière.The present invention relates to the field of irons comprising an ironing surface intended to come into contact with the laundry and a housing provided with a gripping handle in which the housing comprises a lighting device comprising a light source arranged to emit light.

Etat de la techniqueState of the art

Il est connu, du document CN203360895U , un fer à repasser comprenant un dispositif d'éclairage à LED configuré pour éclairer la zone du linge prête à être repasser, la LED étant disposée derrière un capot de protection translucide.It is known, from the document CN203360895U , an iron comprising an LED lighting device configured to illuminate the area of the laundry ready to be ironed, the LED being arranged behind a translucent protective cover.

Un tel fer à repasser présente l'avantage de procurer une ergonomie d'utilisation améliorée en permettant l'éclairage de la zone du linge prête à être repasser et en faisant ressortir les éventuels plis présents sur le linge.Such an iron has the advantage of providing improved ergonomics of use by allowing the area of the linen ready to be ironed to be illuminated and by bringing out any creases present on the linen.

Cependant, dans ce document, la LED est disposée dans une excroissance disgracieuse formée sur le boîtier du fer à repasser, une telle excroissance étant nécessaire pour pouvoir disposer la LED au voisinage immédiat de l'extrémité avant du fer à repasser et éclairer efficacement la zone du linge. En effet, l'extrémité avant du boîtier du fer à repasser présente habituellement une forme effilée qui délimite un volume de faible capacité qui ne permet pas l'intégration du système de LED sans que ce dernier ne forme un bossage sur l'extrémité avant du fer à repasser. Or une telle excroissance sur la partie avant du fer à repasser, en plus d'être disgracieuse, vient gêner la vision de la pointe avant de la surface de repassage, ce qui peut s'avérer gênant lorsque l'utilisateur souhaite effectuer un repassage de précision, par exemple pour le repassage des cols des chemises.However, in this document, the LED is arranged in an unsightly protrusion formed on the housing of the iron, such a protrusion being necessary in order to be able to place the LED in the immediate vicinity of the front end of the iron and to effectively illuminate the area linen. Indeed, the front end of the housing of the iron usually has a tapered shape which delimits a volume of low capacity which does not allow the integration of the LED system without the latter forming a boss on the front end of the iron. However, such a growth on the front part of the iron, in addition to being unsightly, obstructs the vision of the front tip of the ironing surface, which can prove to be annoying when the user wishes to iron precision, for example for ironing shirt collars.

De plus, pour permettre un éclairage rasant faisant ressortir les plis du linge à repasser, la LED doit être disposée relativement proche de la semelle chauffante, c'est-à-dire dans une zone où la température dans le boîtier du fer à repasser est relativement élevée, ce qui peut nuire à la durée de vie du dispositif d'éclairage ou augmenter le cout des composants devant être utilisés pour résister à cette température.In addition, to allow grazing lighting bringing out the folds of the linen to be ironed, the LED must be placed relatively close to the heating soleplate, that is to say in a zone where the temperature in the housing of the iron is relatively high, which may adversely affect the life of the lighting device or increase the cost of the components that must be used to withstand this temperature.

La figure 1 représente un fer à repasser 1 destiné à être relié par un conduit 2 à une base génératrice de vapeur, non représentée sur les figures, la base comportant, de manière connue en soi, une cuve pour la production de vapeur sous une pression de l'ordre de 4 à 6 bars.The figure 1 represents an iron 1 intended to be connected by a conduit 2 to a steam-generating base, not shown in the figures, the base comprising, in a manner known per se, a vessel for the production of steam under a pressure of order of 4 to 6 bars.

Conformément à la figure 2, le fer à repasser 1 comporte une coiffe 10 qui comprend une surface inférieure plane définissant une surface de repassage destinée à venir au contact du linge, la coiffe 10 étant accolée à une semelle chauffante 3 comprenant une paroi inférieure sensiblement plane venant directement au contact de la coiffe 10, cette dernière étant collée sur la semelle chauffante 3 par un adhésif silicone.In accordance with the picture 2 , the iron 1 comprises a cover 10 which comprises a flat lower surface defining an ironing surface intended to come into contact with the laundry, the cover 10 being attached to a heating soleplate 3 comprising a substantially flat lower wall coming directly into contact with the cap 10, the latter being glued to the heating sole 3 by a silicone adhesive.

La coiffe 10 est avantageusement constituée par une tôle en aluminium ou en inox et présente globalement une forme triangulaire avec une extrémité avant pointue et une partie arrière de plus grande largeur se terminant par un bord arrière arrondi.The cap 10 is advantageously made of an aluminum or stainless steel sheet and generally has a triangular shape with a pointed front end and a wider rear part ending in a rounded rear edge.

La semelle chauffante 3 est constituée par une fonderie en aluminium dans laquelle est noyé une résistance électrique blindée 30 en forme de U. La semelle chauffante 3 comporte, de manière connue en soi, un circuit de distribution de vapeur qui est alimentée par le conduit 2 et qui distribue la vapeur au travers de trous 11 de sortie de vapeur ménagés dans la coiffe 10.The heating sole 3 is constituted by an aluminum foundry in which is embedded a shielded electrical resistance 30 in the form of a U.

Le guide de lumière 50 recueille la lumière émise par les sources lumineuses 52 et transmet cette lumière émise vers la surface de projection 51 sur toute sa longueur, pour obtenir un faisceau lumineux uniformément projeté le long du bord de l'extrémité avant de la coiffe 10. Le guide de lumière 50 est réalisé en matière transparente. On peut envisager d'utiliser du polycarbonate, et en particulier un polycarbonate ayant une transmittance élevée pour les ondes lumineuses du domaine visible.The light guide 50 collects the light emitted by the light sources 52 and transmits this emitted light towards the projection surface 51 over its entire length, to obtain a light beam uniformly projected along the edge of the front end of the cap 10 The light guide 50 is made of transparent material. It is possible to envisage using polycarbonate, and in particular a polycarbonate having a high transmittance for the light waves of the visible range.

Le guide de lumière 50 permet de positionner les deux LED à l'intérieur de boîtier 4 du fer à repasser 1 dans une zone du boîtier 4 où la température, lors du fonctionnement de l'appareil, est moins élevée que la température au voisinage de la surface de projection 51. A titre d'exemple, les deux LED sont disposées à distance de la semelle chauffante 3 de telle sorte que la distance séparant les LED de la semelle chauffante 3 est plus importante que la distance séparant la surface de projection 51 de la semelle chauffante 3. Ainsi, les LED se trouvent disposées dans un environnement protégé de la chaleur et des chocs, pour une plus grande robustesse. De plus, les deux LED suffisent pour projeter un faisceau de lumière homogène vers l'avant du fer à repasser 1 et le long du bord avant de la coiffe 10.The light guide 50 makes it possible to position the two LEDs inside the casing 4 of the iron 1 in a zone of the casing 4 where the temperature, during operation of the appliance, is lower than the temperature in the vicinity of the projection surface 51. By way of example, the two LEDs are arranged at a distance from the heating sole 3 such that the distance separating the LEDs from the heating sole 3 is greater than the distance separating the projection surface 51 of the heating sole 3. Thus, the LEDs are arranged in an environment protected from heat and shocks, for greater robustness. In addition, the two LEDs are sufficient for project a homogeneous beam of light towards the front of the iron 1 and along the front edge of the cap 10.

La surface de projection 51 est lisse, et se trouve agencée en regard d'une face opposée 53 qui comporte une pluralité de stries 54. La pluralité de stries 54 est agencée pour réfléchir la lumière émise par les deux LED depuis la face opposée 53 vers la surface de projection 51. Afin de masquer l'intérieur du guide de lumière 50 et rendre la projection du faisceau lumineux la plus homogène possible, la surface de projection 51 est avantageusement dépolie.The projection surface 51 is smooth, and is arranged opposite an opposite face 53 which comprises a plurality of striations 54. The plurality of striations 54 is arranged to reflect the light emitted by the two LEDs from the opposite face 53 towards the projection surface 51. In order to mask the inside of the light guide 50 and make the projection of the light beam as homogeneous as possible, the projection surface 51 is advantageously frosted.

De manière préférentielle, le boîtier 4 du fer à repasser 1 comporte un circuit électronique, avantageusement disposé dans la poignée de préhension 40, et destiné à gérer l'allumage des LED. Ce circuit électronique peut être associé à un interrupteur disposé sur la partie avant de la poignée de préhension 40 qui permet d'allumer ou d'éteindre les LED.Preferably, the housing 4 of the iron 1 includes an electronic circuit, advantageously arranged in the grip handle 40, and intended to manage the switching on of the LEDs. This electronic circuit can be associated with a switch arranged on the front part of the grip handle 40 which allows the LEDs to be switched on or off.

Dans une variante de réalisation préférentielle, le circuit d'électronique pourra comporter un capteur de mouvement, tel un accéléromètre, et commander automatiquement l'allumage des LED, lorsque le fer est mis en mouvement avec la coiffe 10 disposée horizontalement, et l'extinction des LED lorsque le fer à repasser 1 repose verticalement sur son talon.In a preferred embodiment, the electronic circuit may include a motion sensor, such as an accelerometer, and automatically control the lighting of the LEDs, when the iron is set in motion with the cap 10 arranged horizontally, and the extinction LEDs when the iron 1 rests vertically on its heel.

Le fer à réaliser ainsi réalisé présente l'avantage d'offrir une grande ergonomie d'utilisation, grâce à l'éclairage de la zone destinée à être traitée par la surface de repassage, tout en conservant une esthétique valorisante, l'utilisation d'un guide de lumière permettant de déporter la source lumineuse dans une zone du boîtier du fer moins encombrée et plus apte à recevoir la source lumineuse sans dénaturer l'esthétique du fer à repasser.The iron to be produced thus produced has the advantage of offering great ergonomics of use, thanks to the lighting of the zone intended to be treated by the ironing surface, while maintaining a rewarding aesthetic, the use of a light guide making it possible to deport the light source in an area of the iron housing that is less cluttered and more suitable for receiving the light source without distorting the aesthetics of the iron.

De plus, l'utilisation d'un tel guide de lumière permet de disposer la source lumineuse dans une partie du boîtier du fer présentant une température moins élevée, ce qui permet d'améliorer la fiabilité du dispositif d'éclairage.In addition, the use of such a light guide makes it possible to place the light source in a part of the casing of the iron having a lower temperature, which makes it possible to improve the reliability of the lighting device.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is in no way limited to the embodiment described and illustrated which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the field of protection of the invention.

Ainsi, dans une variante de réalisation de l'invention non représentée, le fer à repasser pourra ne pas être relié à une base génératrice de vapeur séparée mais intégrer directement, et de manière connue en soi, une chambre de vaporisation instantanée dans la semelle chauffante, cette chambre de vaporisation pouvant être alimentée par un réservoir d'eau embarquée directement dans le boîtier du fer à repasser ou être disposée dans une base séparée.Thus, in a variant embodiment of the invention not shown, the iron may not be connected to a separate steam-generating base but integrate directly, and in a manner known per se, an instantaneous vaporization chamber in the heating soleplate , this vaporization chamber being able to be fed by a water tank embedded directly in the housing of the iron or to be arranged in a separate base.

Ainsi dans une variante de réalisation de l'invention non représentée, les LED pourront être remplacée par des ampoules halogènes.Thus in a variant embodiment of the invention not shown, the LEDs may be replaced by halogen bulbs.
