Description

La présente invention se rapporte à appareil électroménager pour le traitement du linge à la vapeur comportant un bouton de commande relié à un module de commande pilotant la diffusion de vapeur au travers de trous de sortie de vapeur ménagés sur l'appareil, le bouton de commande permettant de démarrer un premier flux de vapeur, dit standard, ou un deuxième flux de vapeur, dit spécifique, en fonction de la façon dont il est actionné, dans lequel le flux de vapeur spécifique présente des caractéristiques techniques, telles que durée d'émission et/ou température de vapeur et/ou pression de vapeur, distinctes de celles du flux de vapeur standard.The present invention relates to a household appliance for steaming laundry comprising a control button connected to a control module controlling the diffusion of steam through steam outlet holes made on the appliance, the control button making it possible to start a first so-called standard steam stream or a second so-called specific steam stream, depending on how it is actuated, in which the specific steam stream has technical characteristics, such as emission duration and / or vapor temperature and / or vapor pressure, distinct from those of the standard vapor stream.

Il est connu de la demande de brevet WO 2011/076822 un appareil électroménager de repassage comportant une cuve pour la génération de vapeur sous pression reliée par un cordon à un fer à repasser, le fer à repasser comportant un bouton de commande permettant de démarrer, en fonction de la façon dont il est actionné, un premier flux de vapeur correspondant à une séquence illimitée dans le temps de jets de vapeur pulsée ou un deuxième flux de vapeur correspondant à une séquence limitée dans le temps de jets de vapeur.It is known from the patent application WO 2011/076822 a household ironing appliance comprising a tank for generating pressurized steam connected by a cord to an iron, the iron comprising a control button making it possible to start, depending on how it is operated, a first steam flow corresponding to an unlimited time sequence of pulsed steam jets or a second steam flow corresponding to a time limited sequence of steam jets.

Un tel appareil présente l'avantage de permettre à l'utilisateur de choisir, à l'aide d'un même bouton de commande, entre deux types de flux de vapeur afin de sélectionner celui qui convient le mieux aux travaux de repassage qu'il souhaite réaliser. Dans ce document, il est proposé de sélectionner le premier type de flux de vapeur en pressant une fois le bouton de commande et de sélectionner le deuxième type de flux de vapeur en effectuant deux pressions successives sur le bouton de commande à la manière d'un double click sur une souris d'ordinateur.Such a device has the advantage of allowing the user to choose, using the same control button, between two types of steam flow in order to select the one that is best suited to the ironing work he wants. wish to achieve. In this document, it is proposed to select the first type of steam flow by pressing the control button once and to select the second type of steam flow by making two successive pressures on the control button in the manner of a double click on a computer mouse.

Toutefois, à l'usage, une telle solution technique s'avère peu ergonomique pour l'utilisateur, ce dernier pouvant exercer un double click sur le bouton de commande de façon involontaire lorsqu'il relâche momentanément la poignée, et donc la pression exercée sur le bouton de commande, pour modifier la position de sa main, provoquant alors le lancement d'une séquence particulière de jets de vapeur qui n'est pas comprise par l'utilisateur et vient perturber sa séance de repassage.However, in use, such a technical solution proves not very ergonomic for the user, the latter being able to exert an involuntary double click on the control button when he momentarily releases the handle, and therefore the pressure exerted on the control button, to modify the position of his hand, then causing the launching of a particular sequence of steam jets which is not understood by the user and disrupts his ironing session.

Aussi, un but de la présente invention est de proposer un appareil électroménager de repassage remédiant à ces inconvénients. En particulier, un but de la présente invention consiste à proposer un appareil qui permette à l'utilisateur de sélectionner, aisément et de façon ergonomique, un flux de vapeur spécifique, distinct de celui normalement obtenu, par une action particulière sur le bouton de commande de la vapeur de l'appareil, et dans lequel le risque de sélection du flux de vapeur spécifique par un actionnement involontaire du bouton soit limité.Also, an aim of the present invention is to provide a household ironing appliance which overcomes these drawbacks. In particular, an object of the present invention consists in providing an apparatus which allows the user to select, easily and ergonomically, a specific flow of steam, distinct from that normally obtained, by a particular action on the control button. steam from the appliance, and in which the risk of selecting the specific steam flow by unintentional actuation of the button is limited.

A cet effet, l'invention a pour objet un appareil électroménager pour le traitement du linge à la vapeur comportant un bouton de commande relié à un module de commande pilotant la diffusion de vapeur au travers de trous de sortie de vapeur ménagés sur l'appareil, le bouton de commande permettant de démarrer un premier flux de vapeur, dit standard, ou un deuxième flux de vapeur, dit spécifique, en fonction de la façon dont il est actionné, le flux de vapeur spécifique présentant des caractéristiques distinctes de celles du flux de vapeur standard, caractérisé en ce que le module de commande ordonne la diffusion du flux de vapeur spécifique lorsque le bouton de commande est actionné trois fois de suite dans un intervalle de temps inférieur à un temps t1 prédéterminé.To this end, the invention relates to a household appliance for the treatment of laundry with steam comprising a control button connected to a control module controlling the diffusion of steam through steam outlet holes formed on the appliance. , the control button making it possible to start a first stream of steam, said to be standard, or a second stream of steam, said to be specific, depending on the way in which it is activated, the specific stream of steam having characteristics distinct from those of the stream standard steam, characterized in that the control module orders the diffusion of the specific steam flow when the control button is actuated three times in a row within a time interval less than a predetermined time t 1 .

Par caractéristiques du flux de vapeur, on entend notamment les caractéristiques relatives à la durée d'émission et/ou la température de vapeur et/ou la pression de vapeur.The term “characteristics of the vapor flow” is understood to mean in particular the characteristics relating to the duration of emission and / or the vapor temperature and / or the vapor pressure.

Un tel déclenchement du flux de vapeur spécifique par un triple click sur le bouton de commande de la vapeur dans un laps de temps prédéterminé permet à la fois d'éviter le déclenchement involontaire du flux de vapeur spécifique lors de la manipulation de l'appareil et d'offrir une bonne ergonomie d'utilisation lorsque l'utilisateur souhaite déclencher volontairement l'émission du flux de vapeur spécifique. En effet, l'enclenchement du flux de vapeur spécifique par le triple actionnement du bouton de commande dans un laps de temps court reste un geste simple et aisément réalisable par l'utilisateur.Such triggering of the specific steam flow by a triple click on the steam control button within a predetermined period of time makes it possible both to prevent the unintentional triggering of the specific steam flow when handling the device and to offer good ergonomics of use when the user wishes to voluntarily trigger the emission of the specific vapor flow. Indeed, the activation of the specific steam flow by the triple actuation of the control button in a short period of time remains a simple and easily performed gesture by the user.

Selon une autre caractéristique de l'invention, le module de commande ordonne la diffusion du flux de vapeur standard lorsque le bouton de commande est actionné et que le module de commande comptabilise moins de trois actionnements successifs du bouton de commande dans l'intervalle de t1.According to another characteristic of the invention, the control module orders the diffusion of the standard steam flow when the control button is actuated and the control module counts less than three successive actuations of the control button in the interval of t 1 .

Selon une autre caractéristique de l'invention, l'intervalle de temps t1 est inférieur à 2 secondes et préférentiellement de l'ordre d'une seconde.According to another characteristic of the invention, the time interval t 1 is less than 2 seconds and preferably of the order of one second.

Après des tests, la demanderesse s'est rendu compte qu'un tel délai était particulièrement adapté pour offrir une bonne ergonomie d'utilisation et éviter le déclenchement involontaire du flux de vapeur spécifique.After tests, the Applicant realized that such a delay was particularly suitable for offering good ergonomics of use and preventing the involuntary triggering of the specific vapor flow.

Une telle caractéristique permet d'obtenir la diffusion du flux de vapeur standard dés que la commande de vapeur est actionnée, sans être soumise au triple clic.Such a feature makes it possible to obtain the diffusion of the standard steam flow as soon as the steam control is actuated, without being subjected to the triple click.

Selon une autre caractéristique de l'invention, les trous de sortie de vapeur sont alimentés en vapeur par un circuit d'alimentation comportant une électrovanne, l'électrovanne étant pilotée par le module de commande pour contrôler l'émission de vapeur au travers des trous de sortie de vapeur.According to another characteristic of the invention, the steam outlet holes are supplied with steam by a supply circuit comprising a solenoid valve, the solenoid valve being controlled by the control module to control the emission of vapor through the holes. steam outlet.

Selon une autre caractéristique de l'invention, le flux de vapeur standard correspond à une émission en continu de la vapeur.According to another characteristic of the invention, the standard steam flow corresponds to a continuous emission of steam.

Selon une autre caractéristique de l'invention, la durée d'émission du flux de vapeur continu correspond au temps d'actionnement du bouton de commande.According to another characteristic of the invention, the duration of emission of the continuous flow of steam corresponds to the time of actuation of the control button.

Une telle caractéristique permet d'obtenir un flux de vapeur continu dont la durée d'émission correspond directement à la durée d'actionnement de la commande de vapeur par l'utilisateur, permettant à l'utilisateur de contrôler directement le flux de vapeur émis par les trous de sortie de vapeur.Such a characteristic makes it possible to obtain a continuous flow of steam whose emission duration corresponds directly to the duration of actuation of the steam control by the user, allowing the user to directly control the flow of steam emitted by the user. the steam outlet holes.

Selon une autre caractéristique de l'invention, le flux de vapeur spécifique correspond à une émission intermittente de la vapeur.According to another characteristic of the invention, the specific vapor flow corresponds to an intermittent emission of the vapor.

Une telle caractéristique permet d'obtenir un flux de vapeur ayant des jets de vapeur plus puissants que la vapeur obtenue lors de la diffusion en continu, procurant une meilleure pénétration de la vapeur dans les tissus les plus épais.Such a characteristic makes it possible to obtain a stream of steam having more powerful jets of steam than the steam obtained during the continuous diffusion, providing better penetration of the steam into the thicker fabrics.

De manière préférentielle, le flux de vapeur spécifique comporte des phases d'émission de vapeur de l'ordre de 1260 ms alternées avec des phases sans émission de vapeur de l'ordre de 60 ms.Preferably, the specific vapor flow comprises phases vapor emission of the order of 1260 ms alternating with phases without vapor emission of the order of 60 ms.

Selon une autre caractéristique de l'invention, l'émission du flux de vapeur spécifique s'effectue sur une durée prédéterminée.According to another characteristic of the invention, the emission of the specific vapor stream takes place over a predetermined period.

Une telle caractéristique permet d'interrompre automatiquement l'émission du flux de vapeur spécifique au bout d'une durée prédéterminée afin que l'appareil retourne dans un mode d'émission du flux de vapeur normal sans action supplémentaire de la part de l'utilisateur.Such a feature makes it possible to automatically interrupt the emission of the specific vapor flow after a predetermined time so that the device returns to a normal vapor flow emission mode without additional action on the part of the user. .

Selon une autre caractéristique de l'invention, la durée du flux de vapeur spécifique est inférieure ou égale à 6 secondes et de préférence inférieur ou égale à 4 secondes.According to another characteristic of the invention, the duration of the specific vapor flow is less than or equal to 6 seconds and preferably less than or equal to 4 seconds.

Un telle durée correspond au temps habituellement nécessaire pour effectuer les travaux de précision nécessitant des jets de vapeur puissants, tels que le repassage des cols de chemise, plis de pantalon, etc...Such a duration corresponds to the time usually required to perform precision work requiring powerful steam jets, such as ironing shirt collars, trouser folds, etc.

Selon une autre caractéristique de l'invention, le bouton de commande est monostable.According to another characteristic of the invention, the control button is monostable.

Par interrupteur monostable, on entend un interrupteur ne possédant qu'une position stable.By monostable switch is meant a switch having only one stable position.

Pour obtenir ce flux de vapeur standard, la carte électronique 6 commande l'ouverture de l'électrovanne EV lorsque le bouton de commande B est maintenu en position enfoncée et commande la fermeture de l'électrovanne EV lorsque le bouton de commande B occupe la position de repos.The first type of so-called standard steam flow is advantageously constituted by a continuous flow of steam which is delivered through the holes 21 of the sole when the control button B is held in the depressed position. To obtain this standard steam flow, the electronic card 6 controls the opening of the solenoid valve EV when the control button B is kept in the depressed position and commands the closing of the solenoid valve EV when the control button B is in the position rest.

De manière préférentielle, l'ouverture de l'électrovanne EV pour l'émission du flux de vapeur standard ne sera commandée par la carte électronique 6 que si le bouton de commande B est maintenu enfoncé pendant au moins une durée prédéterminée, par exemple de l'ordre de 0,5 s, afin d'éviter l'ouverture de l'électrovanne EV lors d'un appui bref, et involontaire, sur le bouton de commande B.Preferably, the opening of the solenoid valve EV for the emission of the standard steam flow will be controlled by the electronic card 6 only if the control button B is kept pressed for at least a predetermined period, for example of '' order of 0.5 s, in order to prevent the EV solenoid valve from opening when the control button B is pressed briefly and involuntarily.

Plus particulièrement selon l'invention, le deuxième type de flux de vapeur est délivré au travers des trous B de la semelle 20 lorsque le bouton de commande B est actionné au moins trois fois de suite dans un laps de temps donné.More particularly according to the invention, the second type of steam flow is delivered through the holes B of the sole 20 when the control button B is actuated at least three times in a row within a given period of time.

A cet effet, la carte électronique 6 surveille en permanence le nombre d'actionnement du bouton de commande B ayant lieu durant un espace de temps donné, glissant.To this end, the electronic card 6 continuously monitors the number of actuations of the control button B taking place during a given space of time, sliding.

A titre d'exemple, et ainsi que cela est illustré sur la figure 3, la carte électronique 6 surveille sur un intervalle de temps t1 égale à une seconde le nombre d'actionnement du bouton de commande B. Lorsque le bouton de commande B est actionné trois fois de suite sur l'intervalle de temps t1, la carte électronique 6 commande l'émission du deuxième flux de vapeur au travers des trous de sortie de vapeur 21.By way of example, and as illustrated on figure 3 , the electronic card 6 monitors over a time interval t 1 equal to one second the number of actuations of the control button B. When the control button B is actuated three times in a row on the time interval t 1 , the electronic card 6 controls the emission of the second stream of steam through the steam outlet holes 21.

Ce deuxième flux de vapeur, dit spécifique, est avantageusement constitué par une séquence de jets de vapeur successifs qui est émise sur une durée prédéterminée, même si la commande de vapeur B est ramenée en position de repos.This second so-called specific vapor stream is advantageously constituted by a sequence of successive jets of steam which is emitted over a predetermined duration, even if the steam control B is returned to the rest position.

A titre d'exemple, et ainsi que cela est illustré sur la figure 3, le flux de vapeur spécifique est constitué par trois ouvertures successives de l'électrovanne EV pendant une durée de 1260 ms, ces trois ouvertures successives de l'électrovanne EV étant séparées par deux phases de fermeture de l'électrovanne EV d'une durée de 60 ms.By way of example, and as illustrated on figure 3 , the flow of specific vapor is formed by three successive openings of the solenoid valve EV for a duration of 1260 ms, these three successive openings of the solenoid valve EV being separated by two phases of closing of the solenoid valve EV with a duration of 60 ms.

Une telle émission séquentielle de la vapeur présente l'avantage de permettre momentanément, et en particulier à chaque ouverture de l'électrovanne EV, l'obtention d'un jet de vapeur présentant une plus grande pression que celle de la vapeur obtenue avec le flux de vapeur standard. Un tel flux de vapeur spécifique permet ainsi une meilleure imprégnation en vapeur des textiles les plus épais.Such a sequential emission of steam has the advantage of allowing momentarily, and in particular each time the solenoid valve EV is opened, to obtain a jet of steam having a greater pressure than that of the steam obtained with the flow. standard steam. Such a specific steam flow thus allows better steam impregnation of the thickest textiles.

L'émission du flux de vapeur spécifique sera donc avantageusement utilisée ponctuellement lorsque l'utilisateur a besoin de jets de vapeur plus puissants pour le repassage de zones difficiles à repasser telles que les cols de chemise.The emission of the specific steam flow will therefore be advantageously used occasionally when the user needs more powerful steam jets for ironing areas that are difficult to iron, such as shirt collars.

L'appareil de repassage ainsi réalisé présente donc l'avantage d'offrir à l'utilisateur la possibilité de sélectionner un flux de vapeur spécifique, d'une manière sécurisée et ergonomique, à l'aide du même bouton de commande que celui utilisé pour commander l'émission du flux de vapeur en continu.The ironing device thus produced therefore has the advantage of offering the user the possibility of selecting a specific steam flow, in a secure and ergonomic manner, using the same control button as that used for control the emission of the steam flow continuously.

En particulier, la nécessité de cliquer trois fois de suite dans un laps de temps court pour déclencher l'émission du flux de vapeur spécifique permet à la fois d'éviter le déclenchement involontaire du flux de vapeur spécifique lors de la manipulation du fer à repasser, et d'offrir une bonne ergonomie d'utilisation lorsque l'utilisateur souhaite enclencher volontairement le flux de vapeur spécifique, le triple actionnement du bouton de commande dans un laps de temps court restant un geste aisément réalisable par l'utilisateur.In particular, the need to click three times in a row in a short period of time to trigger the emission of the specific steam stream both avoids the unintentional triggering of the specific steam stream when handling the iron. , and to offer good ergonomics of use when the user wishes to voluntarily engage the specific flow of steam, the triple actuation of the control button in a short period of time remaining a gesture easily achievable by the user.

Enfin, un tel appareil présente l'avantage d'être simple et économique à mettre en œuvre, en ne nécessitant pas l'emploi de bouton supplémentaire pour déclencher l'émission du flux de vapeur spécifique.Finally, such a device has the advantage of being simple and economical to use, by not requiring the use of an additional button to trigger the emission of the specific vapor stream.

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 thereby departing from the scope of protection of the invention.

Ainsi, dans une variante de réalisation de l'invention, le flux de vapeur standard et le flux de vapeur spécifique pourront présenter d'autres caractéristiques que celles décrites ci-dessus. A titre d'exemple, le triple actionnement du bouton de commande dans un laps de temps court pourra être utilisé pour déclencher un flux de vapeur spécifique dans lequel l'émission de vapeur s'effectue en continu et se poursuit même après le relâchement de la commande de vapeur, l'interruption du flux de vapeur pouvant ensuite être obtenue en actionnant par exemple de nouveau la commande de vapeur.Thus, in an alternative embodiment of the invention, the standard vapor flow and the specific vapor flow may have characteristics other than those described above. For example, the triple actuation of the control button in a short period of time could be used to trigger a specific flow of steam in which the emission of steam takes place continuously and continues even after the release of the steam. steam control, the interruption of the steam flow can then be obtained by, for example, actuating the steam control again.

Ainsi, dans une variante de réalisation de l'invention non représentée, la cuve pour la génération de vapeur sous pression pourra être intégrée dans le corps du fer à repasser.Thus, in an alternative embodiment of the invention not shown, the tank for the generation of pressurized steam can be integrated into the body of the iron.

Ainsi, dans encore une variante de réalisation non représentée, l'appareil pourra être un fer à repasser comprenant une chambre de vaporisation instantanée qui est alimentée en eau d'un réservoir au moyen d'une pompe. Dans cette variante de réalisation, le flux de vapeur produit par la chambre de vaporisation pourra être contrôlé en pilotant le fonctionnement de la pompe au moyen d'un module de commande.Thus, in yet another variant embodiment not shown, the apparatus may be an iron comprising an instantaneous vaporization chamber which is supplied with water from a reservoir by means of a pump. In this variant embodiment, the flow of vapor produced by the vaporization chamber can be controlled by controlling the operation of the pump by means of a control module.
