Description
La présente invention se rapporte à un fer à repasser à vapeur comprenant un corps chauffant muni d'une chambre de vaporisation et se rapporte plus particulièrement à un fer à repasser comportant un indicateur d'entartrage permettant d'alerter l'utilisateur sur la nécessité d'effectuer une opération de maintenance.The present invention relates to a steam iron comprising a heating body provided with a vaporization chamber and relates more particularly to an iron with a scaling indicator to alert the user to the need for perform a maintenance operation.
Il est connu, de la demande de brevet
Un tel indicateur d'entartrage présente l'avantage d'inciter régulièrement l'utilisateur à effectuer une opération d'auto-nettoyage du fer pour évacuer les particules de tartre accumulées dans la chambre de vaporisation.Such an indicator of scaling has the advantage of regularly encouraging the user to perform a self-cleaning operation of the iron to remove scale particles accumulated in the steam chamber.
Cependant, une telle méthode d'activation de l'indicateur d'entartrage présente l'inconvénient d'être peu représentative de l'état réel de calcification du fer dans son mode de réalisation le plus simple et d'être relativement coûteuse dans sa variante la plus complexe, cette variante étant de plus inutilisable sur les fers à vapeur comprenant un simple dispositif goutte-à-goutte à la place de la pompe pour alimenter la chambre de vaporisation.However, such a method of activating the scaling indicator has the disadvantage of being poorly representative of the actual state of iron calcification in its simplest embodiment and of being relatively expensive in its variant. the most complex, this variant being more unusable on steam irons comprising a simple device drip instead of the pump to feed the vaporization chamber.
L'invention qui suit vise à pallier ces inconvénients en proposant un fer à vapeur muni d'un indicateur d'entartrage dans lequel l'indicateur est activé au moyen d'une méthode d'activation pouvant être utilisée sur les fers vapeurs les plus simples et permettant d'obtenir une meilleure adéquation entre l'état réel d'entartrage du fer et l'activation de l'indicateur d'entartrage tout en restant simple et économique à réaliser.The following invention aims to overcome these disadvantages by providing a steam iron with a scaling indicator in which the indicator is activated by means of an activation method that can be used on the simplest steam irons and to obtain a better match between the actual state of scaling iron and the activation of the scaling indicator while remaining simple and economical to achieve.
Le but de l'invention est atteint par un fer à vapeur comportant un indicateur d'entartrage et comprenant un corps chauffant comportant une chambre de vaporisation pour la production de vapeur, caractérisé en ce qu'il comprend des moyens permettant de calculer une énergie électrique consommée par le fer et des moyens servant à activer ledit indicateur d'entartrage lorsque l'énergie calculée dépasse un seuil préalablement déterminé.The object of the invention is achieved by a steam iron comprising a scaling indicator and comprising a heating body comprising a vaporization chamber for the production of steam, characterized in that it comprises means for calculating an electrical energy. consumed by the iron and means for activating said scaling indicator when the calculated energy exceeds a previously determined threshold.
Un tel fer, dans lequel l'activation de l'indicateur d'entartrage se base sur le calcul d'une énergie consommée, permet d'obtenir une meilleure estimation de l'état d'entartrage du fer. En effet, dans un fer à production de vapeur au moyen d'une chambre de vaporisation, l'essentiel de l'énergie consommée est dépensé lors de la vaporisation de l'eau.Such an iron, in which the activation of the scaling indicator is based on the calculation of energy consumed, provides a better estimate of the scaling state of iron. Indeed, in a steam iron by means of a steam chamber, most of the energy consumed is spent during the vaporization of the water.

Selon une autre caractéristique de l'invention, les moyens pour mesurer le temps cumulé de fonctionnement de la résistance chauffante sont intégrés à un circuit électronique commandant l'activation de l'indicateur d'entartrage, ce circuit électronique recevant du thermostat l'information relative à l'alimentation ou non de la résistance chauffante.According to another characteristic of the invention, the means for measuring the cumulative operating time of the heating resistor are integrated in an electronic circuit controlling the activation of the scaling indicator, this electronic circuit receiving from the thermostat the relative information. whether the heating resistor is powered or not.
Selon une autre caractéristique de l'invention, le fer comprend des moyens pour calculer la quantité d'énergie consommée par la résistance chauffante, l'indicateur d'entartrage étant activé lorsque la quantité d'énergie consommée par la résistance chauffante dépasse un seuil préalablement déterminé.According to another characteristic of the invention, the iron comprises means for calculating the amount of energy consumed by the heating resistor, the scaling indicator being activated when the amount of energy consumed by the heating resistor exceeds a threshold previously determined.

Selon une autre caractéristique de l'invention, l'énergie consommée pour produire de la vapeur est calculée en soustrayant, de l'énergie consommée par la résistance chauffante, une estimation de l'énergie nécessaire pour le repassage à sec d'un textile à la température de consigne du thermostat.According to another characteristic of the invention, the energy consumed to produce steam is calculated by subtracting, from the energy consumed by the heating resistor, an estimate of the energy required for the heating. Dry ironing of a textile at the set temperature of the thermostat.
Selon encore une autre caractéristique de l'invention, l'énergie nécessaire pour le repassage à sec d'un textile à la température de réglage du thermostat est estimée en intégrant dans le temps une puissance standard nécessaire pour le repassage à sec d'un textile à la température de réglage du thermostat, la valeur de cette puissance étant déterminée à partir de valeurs stockées dans une mémoire du circuit électronique.According to yet another characteristic of the invention, the energy required for the dry ironing of a textile at the thermostat control temperature is estimated by integrating over time a standard power required for the dry ironing of a textile at the thermostat setting temperature, the value of this power being determined from values stored in a memory of the electronic circuit.
Selon une autre caractéristique de l'invention, le seuil d'activation de l'indicateur d'entartrage est modulé en fonction du degré de dureté de l'eau introduite dans la chambre de vaporisation qui est indiqué par l'utilisateur.According to another characteristic of the invention, the activation threshold of the scaling indicator is modulated according to the degree of hardness of the water introduced into the vaporization chamber which is indicated by the user.
Selon encore une autre caractéristique de l'invention, le fer comporte un bouton dont l'actionnement permet, lorsque l'indicateur d'entartrage est activé, de réinitialiser le calcul de l'énergie électrique consommée.According to yet another characteristic of the invention, the iron comprises a button whose actuation allows, when the scaling indicator is activated, to reset the calculation of the electrical energy consumed.

On comprendra mieux les buts, aspects et avantages de la présente invention, d'après la description donnée ci-après d'un mode particulier de réalisation de l'invention, présenté à titre d'exemple non limitatif, en se référant au dessin annexé dans lequel :
- La
figure 1 est une vue schématique en coupe longitudinale d'un fer à vapeur selon un mode de réalisation particulier de l'invention.
- The
figure 1 is a schematic longitudinal sectional view of a steam iron according to a particular embodiment of the invention.
Seuls les éléments nécessaires à la compréhension de l'invention ont été représentés.Only the elements necessary for the understanding of the invention have been represented.
Le fer, représenté schématiquement à la
Le corps chauffant 3 comprend une résistance chauffante 31 alimentée par un thermostat 6 en relation thermique avec le corps chauffant, le thermostat 6 assurant la régulation de la température de la semelle 2 autour d'une température de consigne définie par l'utilisateur au moyen d'un bouton 60. Le fer est relié au réseau électrique par un cordon 5.The
De manière connue en soi, le boîtier 1 renferme un réservoir d'eau 8 muni d'un orifice 8a de remplissage débouchant sur la face avant du fer et comporte un dispositif goutte à goutte 9 qui ménage un passage de l'eau du réservoir 8 vers la chambre de vaporisation 30, ce dispositif possédant classiquement un orifice dont la section peut être réduite par un pointeau.In a manner known per se, the
Afin de prévenir l'utilisateur sur la nécessité d'effectuer une opération de détartrage de fer, ce dernier comporte un indicateur d'entartrage constitué par un voyant 10 qui est activé par un circuit électronique 11. Ce circuit électronique 11 est avantageusement alimenté en électricité par le réseau électrique lorsque le cordon 5 du fer à vapeur est raccordé au réseau.In order to warn the user of the need to carry out an iron descaling operation, the latter includes a scaling indicator consisting of a
Plus particulièrement selon l'invention, le circuit électronique 11 est relié au thermostat 6 et reçoit de ce dernier l'information relative aux périodes d'alimentation en électricité de la résistance chauffante 31.More particularly according to the invention, the
A partir de cette information, le circuit électronique 11 renferme un microprocesseur qui mesure l'énergie électrique consommée par la résistance chauffante 31 depuis la première utilisation du fer. Cette mesure est effectuée avantageusement en intégrant dans le temps la puissance de la résistance chauffante 31, qui est par exemple de l'ordre de 2000 W, pendant le temps de fonctionnement de la résistance chauffante 31, ce temps de fonctionnement étant déterminé directement à partir du temps de fermeture du thermostat 6.From this information, the
L'accumulation de l'énergie consommée est enregistrée dans une mémoire du circuit électronique 11, de préférence une mémoire non volatile telle qu'une mémoire flash ou EEPROM. Dans une variante, le circuit électronique 11 peut également comporter un dispositif d'alimentation autonome, tel une batterie ou un condensateur, pour conserver la donnée en mémoire lorsque le cordon d'alimentation 5 du fer à vapeur est déconnecté du réseau.The accumulation of the energy consumed is recorded in a memory of the
Lorsque le cumul de l'énergie consommée par la résistance chauffante 31 atteint un seuil prédéterminé, le circuit électronique 11 active le voyant 10, par exemple de manière clignotante, pour inviter l'opérateur à effectuer une opération de détartrage.When the cumulative energy consumed by the
L'utilisateur est alors invité à effectuer une opération de détartrage du fer en positionnant par exemple le thermostat 6 sur la température maximale et en appuyant sur un bouton d'auto-nettoyage 12 prévu sur le fer de manière à provoquer, de manière connue en soi, une arrivée brutale d'eau du réservoir 8 vers la chambre de vaporisation 30 pour obtenir le décollement des particules de tartre et leur évacuation au travers des trous de vapeur de la semelle 2.The user is then invited to perform a descaling operation of the iron, for example by setting the
De manière préférentielle, le circuit électronique 11 est relié au bouton d'auto-nettoyage 12 et effectue, lors de actionnement du bouton d'auto-nettoyage, une remise à zéro de la mémoire dans laquelle est stocké le cumul de l'énergie consommée par la résistance chauffante 31.Preferably, the
A titre d'exemple, la valeur du seuil à partir duquel le voyant 10 est activé est obtenu expérimentalement en faisant fonctionner des fers à pleine vapeur avec de l'eau moyennement calcaire et en mesurant le seuil à partir duquel l'état d'entartrage du fer nécessite une opération de détartrage.By way of example, the value of the threshold from which the
Une telle activation du voyant d'entartrage à partir de la mesure de la somme de l'énergie consommée par la résistance chauffante permet d'obtenir, d'une façon simple, une bonne adéquation entre l'état réel d'entartrage du fer et l'activation du voyant indicateur d'entartrage. En effet, l'évaporation de l'eau pour la production de vapeur étant fortement consommatrice d'énergie, le voyant indicateur d'entartrage du fer sera activé beaucoup plus rapidement lorsque le fer sera utilisé pour repasser à la vapeur que lorsque le fer sera utilisé pour repasser à sec. Or, l'entartrage du fer dépend essentiellement de la quantité d'eau qui est évaporée dans la chambre de vaporisation.Such activation of the scaling indicator from the measurement of the sum of the energy consumed by the heating resistor makes it possible, in a simple manner, to obtain a good match between the actual state of scaling of the iron and activation of the scaling indicator light. Indeed, the evaporation of water for the production of steam being strongly energy consuming, the indicator indicator of scaling of the iron will be activated much more quickly when the iron will be used to iron when the iron will be used for dry ironing. However, the scaling of iron depends essentially on the amount of water that is evaporated in the vaporization chamber.
Dans une variante perfectionnée du mode de réalisation précédemment décrit, la détermination de l'état d'entartrage du fer sera encore améliorée en calculant l'énergie consommée par la résistance 31 utilisée uniquement pour évaporer l'eau. On obtient ainsi une très bonne estimation de la quantité d'eau évaporée dans la chambre de vaporisation, cette dernière étant en corrélation directe avec l'énergie dépensée pour la vaporisation.In an improved variant of the embodiment described above, the determination of the scaling state of the iron will be further improved by calculating the energy consumed by the
Dans cette variante, le circuit électronique 11 calcule de manière approchée l'énergie utilisée pour évaporer l'eau en soustrayant, du cumul de l'énergie consommée par la résistance 31, une estimation de l'énergie nécessaire pour maintenir la semelle 2 à la température de consigne du thermostat 6 lors d'un repassage à sec du textile.In this variant, the
Cette énergie nécessaire au repassage à sec est estimée en intégrant dans le temps une puissance standard nécessaire au repassage à sec du textile pour la température de consigne. De manière avantageuse, la valeur de cette puissance standard est déterminée par corrélation à partir de valeurs standards de puissance, stockées dans une mémoire du circuit électronique 11, pour différentes valeurs de température de la semelle 2.This energy required for dry ironing is estimated by integrating over time a standard power required for dry ironing the textile for the set temperature. Advantageously, the value of this standard power is determined by correlation from standard power values, stored in a memory of the
A titre d'exemple, ces valeurs de puissance standard sont de l'ordre de 100 W pour une température de semelle proche de 100°C et de 300 W pour une température de semelle proche de 200°C.By way of example, these standard power values are of the order of 100 W for a sole temperature close to 100 ° C. and 300 W for a sole temperature close to 200 ° C.
Le circuit électronique 11 calcule alors simplement, à partir de ces valeurs, l'énergie consommée pour l'évaporation de l'eau en intégrant, sur le temps de fonctionnement de la résistance chauffante 31, déterminé à partir du thermostat 6, la puissance consommée par la résistance chauffante 31 à laquelle est soustraite la puissance standard utilisée pour maintenir la semelle 2 à la température de consigne.The
Lorsque l'énergie consommée pour l'évaporation de l'eau dans la chambre de vaporisation dépasse un seuil prédéterminé, correspondant par exemple à l'énergie nécessaire pour évaporer 15 litres d'eau, l'indicateur d'entartrage est alors activé.When the energy consumed for the evaporation of water in the vaporization chamber exceeds a predetermined threshold, corresponding for example to the energy required to evaporate 15 liters of water, the scaling indicator is then activated.
De manière avantageuse, le fer peut également comporter des moyens permettant à l'utilisateur d'indiquer le degré de dureté de l'eau introduite dans le réservoir, de sorte que la dureté de l'eau puisse être prise en compte par le circuit électronique 11 pour adapter le seuil d'activation du voyant 10 indicateur d'entartrage en fonction de la dureté de l'eau.Advantageously, the iron may also comprise means allowing the user to indicate the degree of hardness of the water introduced into the reservoir, so that the hardness of the water can be taken into account by the electronic circuit. 11 to adapt the activation threshold of
Une telle variante permet d'améliorer encore l'adéquation entre l'activation de l'indicateur d'entartrage et l'état réel d'entartrage du fer. En particulier, avec une telle variante, l'activation de l'indicateur d'entartrage n'aura pas lieu, ou seulement après une très grande durée d'utilisation du fer, si l'utilisateur repasse essentiellement à sec.Such a variant makes it possible to further improve the adequacy between the activation of the scaling indicator and the actual state of scaling of the iron. In particular, with a alternatively, the activation of the scaling indicator will not take place, or only after a very long period of use of iron, if the user goes back essentially dry.
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 not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
Ainsi, dans une variante de réalisation de l'invention, le thermostat mécanique du fer pourra être remplacé par un thermostat électronique relié à des capteurs de température.Thus, in an alternative embodiment of the invention, the mechanical thermostat of the iron may be replaced by an electronic thermostat connected to temperature sensors.
