Un autre exemple de procédé de nettoyage es également connu du document EP 2 397 063 qui divulgue un procédé de nettoyage dans lequel de l'eau est envoyée dans la chambre de vaporisation froide puis la chambre de vaporisation est chauffée pour faire bouillir l'eau présente dans la chambre de vaporisation.Another example of a cleaning process is also known from the document EP 2 397 063 which discloses a cleaning process in which water is sent to the cold vaporization chamber and then the vaporization chamber is heated to boil the water present in the vaporization chamber.

Un tel procédé de nettoyage présente toutefois une efficacité de nettoyage insatisfaisante, ce qui peut nuire à la durée de vie du fer à repasser. En outre, une efficacité de nettoyage insatisfaisante requiert des opérations de nettoyage du fer à repasser plus rapprochées dans le temps, ce qui peut être contraignant pour un utilisateur.Such a cleaning method, however, has an unsatisfactory cleaning efficiency, which can adversely affect the service life of the iron. In addition, unsatisfactory cleaning efficiency requires cleaning operations of the iron which are shorter in time, which can be restrictive for a user.

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.

Le problème technique à la base de l'invention consiste notamment à fournir un procédé de nettoyage d'un fer à repasser qui soit efficace et peu contraignant pour un utilisateur.The technical problem underlying the invention consists in particular in providing a method for cleaning an iron which is efficient and not very restrictive for a user.

A cet effet, la présente invention concerne un procédé de nettoyage d'un fer à repasser comportant une semelle de repassage surmontée d'un corps chauffant comprenant une chambre de vaporisation et un circuit de distribution de vapeur configuré pour alimenter des orifices de sortie de vapeur ménagés dans la semelle de repassage, le circuit de distribution de vapeur comportant une cavité de récupération de tartre comprenant un orifice d'évacuation fermé par un bouchon amovible accessible depuis l'extérieur du fer à repasser, la chambre de vaporisation étant destinée à être alimentée en eau au moyen d'une pompe d'alimentation, dans lequel le procédé de nettoyage comprend :

  • une première étape d'injection d'eau dans la chambre de vaporisation au moyen de la pompe d'alimentation, le temps de fonctionnement de la pompe d'alimentation durant la première étape d'injection d'eau étant supérieur au temps nécessaire pour que le volume d'eau envoyé par la pompe d'alimentation recouvre la majeure partie du fond de la chambre de vaporisation et avantageusement supérieur au temps nécessaire pour que l'eau remonte par le circuit de distribution de vapeur jusqu'à sortir par au moins un orifice de sortie de vapeur de la semelle de repassage,
  • une deuxième étape de chauffage de la chambre de vaporisation à une température supérieure à 100°C, pour faire bouillir l'eau présente dans la chambre de vaporisation,
  • une troisième étape d'injection d'eau dans la chambre de vaporisation au moyen de la pompe d'alimentation, le fer à repasser étant maintenu, durant la troisième étape d'injection d'eau, dans une position de nettoyage dans laquelle l'eau injectée par la pompe d'alimentation dans la chambre de vaporisation entraîne des particules de tartre dans la cavité de récupération de tartre,
  • une quatrième étape durant laquelle le fonctionnement de la pompe d'alimentation est interrompu et la chambre de vaporisation est amenée à une température supérieure à 150°C pour vaporiser rapidement l'eau présente dans la chambre de vaporisation, et
  • une cinquième étape d'évacuation du tartre récolté dans la cavité de récupération de tartre en ouvrant le bouchon amovible.
To this end, the present invention relates to a method for cleaning an iron comprising an ironing sole surmounted by a heating body comprising a vaporization chamber and a steam distribution circuit configured to supply steam outlet orifices. formed in the ironing sole, the steam distribution circuit comprising a scale recovery cavity comprising an evacuation orifice closed by a removable plug accessible from outside the iron, the vaporization chamber being intended to be supplied in water by means of a feed pump, in which the cleaning process comprises:
  • a first step of injecting water into the vaporization chamber by means of the feed pump, the operating time of the feed pump during the first step of injecting water being greater than the time required for the volume of water sent by the feed pump covers most of the bottom of the vaporization chamber and advantageously greater than the time required for the water to rise through the vapor distribution circuit until it leaves through at least one ironing soleplate steam outlet,
  • a second step of heating the vaporization chamber to a temperature above 100 ° C, to boil the water present in the vaporization chamber,
  • a third step of injecting water into the vaporization chamber by means of the feed pump, the iron being maintained, during the third step of injecting water, in a cleaning position in which the water injected by the feed pump into the vaporization chamber entrains scale particles in the scale recovery cavity,
  • a fourth step during which the operation of the pump supply is interrupted and the vaporization chamber is brought to a temperature above 150 ° C to rapidly vaporize the water present in the vaporization chamber, and
  • a fifth step of removing the scale collected in the scale recovery cavity by opening the removable cap.

Grâce à l'agitation provoquée par l'ébullition de l'eau lors de la deuxième étape, les particules de tartre présentes dans la chambre de vaporisation se décollent des parois intérieures de la chambre de vaporisation. En outre, l'injection d'eau dans la troisième étape permet le rinçage de la chambre de vaporisation et du circuit de distribution de vapeur, et permet d'entrainer les particules de tartre dans la cavité de récupération de tartre. Lorsque l'injection d'eau dans la chambre de vaporisation est stoppée, le fer à repasser est amené à haute température de manière à ce que l'eau présente notamment dans la chambre de vaporisation se vaporise rapidement. Après vaporisation de sensiblement toute l'eau contenue dans la chambre de vaporisation et le circuit de distribution de vapeur, le bouchon amovible peut être enlevé et la cavité de récupération de tartre peut être vidée des particules de tartre accumulées dans cette dernière.Thanks to the agitation caused by the boiling of the water during the second step, the scale particles present in the vaporization chamber are detached from the interior walls of the vaporization chamber. In addition, the injection of water in the third step allows the rinsing of the vaporization chamber and the steam distribution circuit, and allows the scale particles to be drawn into the scale recovery cavity. When the injection of water into the vaporization chamber is stopped, the iron is brought to high temperature so that the water present in particular in the vaporization chamber vaporizes rapidly. After vaporization of substantially all of the water contained in the vaporization chamber and the vapor distribution circuit, the removable plug can be removed and the scale recovery cavity can be emptied of scale particles accumulated therein.

Le procédé de nettoyage selon la présente invention permet ainsi de récolter, pendant l'opération de nettoyage du fer à repasser, un maximum de tartre dans la cavité de récupération de tartre prévue à cet effet. Il en résulte une amélioration de l'efficacité du nettoyage du fer à repasser et donc une augmentation de la durée de vie du fer à repasser. En outre, le procédé de nettoyage selon la présente invention permet d'espacer les différentes opérations de nettoyage du fer à repasser, et donc également les contraintes liées à de telles opérations de nettoyage.The cleaning process according to the present invention thus makes it possible to collect, during the cleaning operation of the iron, a maximum of scale in the scale recovery cavity provided for this purpose. This results in an improvement in the cleaning efficiency of the iron and therefore an increase in the life of the iron. In addition, the cleaning method according to the present invention makes it possible to space out the various cleaning operations of the iron, and therefore also the constraints associated with such cleaning operations.

Le procédé de nettoyage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The cleaning process may further exhibit one or more of the following characteristics, taken alone or in combination.

Selon un mode de mise en œuvre du procédé de nettoyage, le temps de fonctionnement de la pompe d'alimentation durant la troisième étape d'injection d'eau est supérieur au temps nécessaire pour que le volume d'eau envoyé par la pompe d'alimentation remplisse la majeure partie de la cavité de récupération de tartre et avantageusement supérieur au temps nécessaire pour que l'eau remonte par le circuit de distribution de vapeur jusqu'à sortir par au moins un orifice de sortie de vapeur de la semelle de repassage.According to one embodiment of the cleaning process, the operating time of the feed pump during the third water injection step is greater than the time required for the volume of water sent by the pump to feed fills the major part of the scale collection cavity and advantageously longer than the time required for the water rises through the steam distribution circuit until it exits through at least one steam outlet opening of the ironing sole.

Ainsi, l'eau remplit la chambre de vaporisation et la cavité de récupération de tartre, jusqu'à s'écouler avantageusement par au moins un orifice de sortie de vapeur du fer à repasser. Une partie de l'eau injectée dans la chambre de vaporisation est donc évacuée vers l'avant du fer à repasser, ce qui permet de rincer le circuit de distribution mais le tartre, plus lourd, reste dans la cavité de récupération de tartre qui est avantageusement située à l'arrière du fer à repasser.Thus, the water fills the vaporization chamber and the scale recovery cavity, until it advantageously flows through at least one steam outlet of the iron. Part of the water injected into the vaporization chamber is therefore evacuated towards the front of the iron, which makes it possible to rinse the distribution circuit but the scale, which is heavier, remains in the scale recovery cavity which is advantageously located at the rear of the iron.

Selon un mode de mise en œuvre du procédé de nettoyage, les première, deuxième, troisième et quatrième étapes sont réalisées automatiquement par le fer à repasser, par exemple après l'actionnement d'un bouton de commande par un utilisateur.According to one embodiment of the cleaning method, the first, second, third and fourth steps are performed automatically by the iron, for example after the actuation of a control button by a user.

Selon un mode de réalisation de l'invention, le débit d'eau injecté dans la chambre de vaporisation lors de la première étape est supérieur à un débit d'eau maximal injecté dans la chambre de vaporisation lors d'une étape de repassage. Avantageusement, le débit d'eau injecté dans la chambre de vaporisation lors de la première étape est sensiblement égal ou supérieur au double du débit d'eau maximal injecté dans la chambre de vaporisation lors d'une étape de repassage.According to one embodiment of the invention, the water flow rate injected into the vaporization chamber during the first step is greater than a maximum water flow rate injected into the vaporization chamber during an ironing step. Advantageously, the flow of water injected into the vaporization chamber during the first step is substantially equal to or greater than twice the maximum flow of water injected into the vaporization chamber during an ironing step.

Selon un mode de réalisation de l'invention, la troisième étape est déclenchée dès que la chambre de vaporisation atteint une température de consigne lors de la deuxième étape.According to one embodiment of the invention, the third step is triggered as soon as the vaporization chamber reaches a set temperature during the second step.

Selon un mode de réalisation de l'invention, la chambre de vaporisation est chauffée pendant la troisième étape d'injection d'eau.According to one embodiment of the invention, the vaporization chamber is heated during the third water injection step.

Selon un mode de réalisation avantageux de l'invention, le procédé comporte une étape additionnelle, mise en œuvre à la fin de la quatrième étape, dans laquelle de l'eau est injectée dans la chambre de vaporisation au moyen de la pompe durant un temps prédéterminé, avantageusement inférieur à 5 secondes, pour générer momentanément une forte production de vapeur sans noyer la chambre de vaporisation.According to an advantageous embodiment of the invention, the method comprises an additional step, implemented at the end of the fourth step, in which water is injected into the vaporization chamber by means of the pump for a predetermined time, advantageously less than 5 seconds, to momentarily generate a high production of steam without flooding the vaporization chamber.

Une telle caractéristique permet de générer un flux de vapeur brutal et momentané à la fin du procédé de nettoyage qui permet de chasser, par les orifices de sortie de vapeur, les éventuelles particules de tartre encore présentes dans le circuit de distribution de vapeur et susceptibles d'être envoyées au travers des orifices de sortie de vapeur de la semelle de repassage. On évite ainsi que ces particules de tartre ne soient envoyées vers le linge lors de la prochaine utilisation du fer à repasser.Such a characteristic makes it possible to generate a sudden and momentary flow of steam at the end of the cleaning process which makes it possible to drive out, through the steam outlet openings, any scale particles still present in the steam distribution circuit and liable to damage. '' be sent through the steam outlet openings of the ironing sole. This prevents these particles of scale from being sent to the laundry the next time the iron is used.

Grâce à l'agitation provoquée par l'ébullition dans la chambre de vaporisation 17 lors de la deuxième étape, les particules de tartre présentes dans la chambre de vaporisation 17 se décollent des parois intérieures de la chambre de vaporisation 17.Thanks to the agitation caused by the boiling in the vaporization chamber 17 during the second step, the scale particles present in the vaporization chamber 17 become detached from the interior walls of the vaporization chamber 17.

Ainsi, lors de la deuxième étape, une partie des particules de tartre soulevée par l'ébullition dans la chambre de vaporisation 17 tombe par gravité dans la cavité de récupération du tartre 32.Thus, during the second step, part of the scale particles raised by the boiling in the vaporization chamber 17 fall by gravity into the scale recovery cavity 32.

A la fin de la deuxième étape, de l'eau est encore présente dans la chambre de vaporisation 17 et dans le circuit de distribution de vapeur 27, et le flux d'eau injecté lors de la troisième étape entraîne le reste des particules de tartre présentes dans la chambre de vaporisation 17 dans la cavité de récupération de tartre 32.At the end of the second stage, water is still present in the vaporization chamber 17 and in the steam distribution circuit 27, and the flow of water injected during the third stage entrains the rest of the scale particles. present in the vaporization chamber 17 in the scale recovery cavity 32.

L'eau, en continuant de s'écouler, remplit la chambre de vaporisation 17 et la cavité de récupération de tartre 32, jusqu'à avantageusement s'écouler par au moins un orifice de sortie de vapeur 12 du fer à repasser 3. Une partie de l'eau injectée dans la chambre de vaporisation 17 est donc évacuée vers l'avant du fer à repasser 3 mais le tartre, plus lourd, reste dans la cavité de récupération de tartre 32 qui est située à l'arrière du fer à repasser 3.The water, continuing to flow, fills the vaporization chamber 17 and the scale recovery cavity 32, until it advantageously flows through at least one steam outlet 12 of the iron 3. A part of the water injected into the vaporization chamber 17 is therefore discharged towards the front of the iron 3 but the scale, which is heavier, remains in the scale recovery cavity 32 which is located at the rear of the iron. iron 3.

Lorsque l'injection d'eau dans la chambre de vaporisation 17 est stoppée (au début de la quatrième étape), la semelle de repassage 9 est amenée à une température de consigne plus élevée, de l'ordre de 210°C, et l'eau présente notamment dans la chambre de vaporisation 17 et dans le circuit de distribution de vapeur 27 se vaporise rapidement.When the injection of water into the vaporization chamber 17 is stopped (at start of the fourth step), the ironing sole 9 is brought to a higher set temperature, of the order of 210 ° C, and the water present in particular in the vaporization chamber 17 and in the distribution circuit of vapor 27 vaporizes quickly.

Après vaporisation de sensiblement toute l'eau contenue dans la chambre de vaporisation 17 et le circuit de distribution de vapeur 27, le bouchon amovible 34 peut alors être enlevé et la cavité de récupération de tartre 32 peut être vidée des particules de tartre accumulées dans cette dernière lors de la troisième étape.After vaporization of substantially all of the water contained in the vaporization chamber 17 and the vapor distribution circuit 27, the removable plug 34 can then be removed and the scale recovery cavity 32 can be emptied of the scale particles accumulated in this last in the third step.

Selon un mode de réalisation avantageux de l'invention, le débit d'eau injecté dans la chambre de vaporisation 17 lors des première et troisième étapes est sensiblement égal ou supérieur au double d'un débit d'eau maximal injecté dans la chambre de vaporisation 17 lors d'une phase de repassage d'un linge à repasser.According to an advantageous embodiment of the invention, the flow of water injected into the vaporization chamber 17 during the first and third stages is substantially equal to or greater than twice a maximum flow of water injected into the vaporization chamber. 17 during an ironing phase of a laundry to be ironed.

Selon un mode de réalisation avantageux de l'invention, le procédé de nettoyage automatique du fer à repasser 3 comporte une étape additionnelle mise en œuvre à la fin de la quatrième étape. Lors de cette étape additionnelle, de l'eau est injectée dans la chambre de vaporisation 17 au moyen de la pompe P pendant un temps prédéterminé, bien inférieur au temps d'injection d'eau de la troisième étape, pour générer momentanément une forte production de vapeur sans toutefois noyer la chambre de vaporisation 17. A titre d'exemple, le temps d'injection d'eau lors de cette étape additionnelle est de l'ordre de 3 secondes.According to an advantageous embodiment of the invention, the method for automatically cleaning the iron 3 comprises an additional step implemented at the end of the fourth step. During this additional step, water is injected into the vaporization chamber 17 by means of the pump P for a predetermined time, much less than the water injection time of the third step, to temporarily generate a high production vapor without flooding the vaporization chamber 17. By way of example, the water injection time during this additional step is of the order of 3 seconds.

La chambre de vaporisation 17 se trouvant alors à une température de l'ordre de 210°C, le fort flux de vapeur généré par l'injection d'eau va chasser, par les orifices de sortie de vapeur 12, les éventuelles particules de tartre encore présentes dans le circuit de distribution de vapeur, ce qui permet d'éviter que ces particules de tartre ne soient envoyées vers le linge au cours de la séance de repassage suivante.The vaporization chamber 17 then being at a temperature of the order of 210 ° C, the strong flow of steam generated by the injection of water will drive out, through the steam outlet orifices 12, any particles of scale. still present in the steam distribution circuit, which prevents these particles of scale from being sent to the laundry during the next ironing session.

Selon un mode de réalisation de l'invention, le fer à repasser 3 pourrait comporter un indicateur d'entartrage avertissant l'utilisateur de la nécessité de procéder à un programme de nettoyage automatique de la chambre de vaporisation 17. Un tel indicateur d'entartrage pourra être activé en fonction du temps d'utilisation du fer à repasser 3 ou du nombre de remplissages du réservoir d'eau 5 et sa fréquence d'activation pourra être modulée en fonction de la position d'un indicateur de dureté de l'eau.According to one embodiment of the invention, the iron 3 could include a scale indicator warning the user of the need to carry out an automatic cleaning program for the steam chamber. vaporization 17. Such an indicator of scaling can be activated according to the time of use of the iron 3 or the number of times the water tank 5 has been filled and its frequency of activation can be modulated according to the position d 'a water hardness indicator.

Les figures 14 et 15 représentent un fer à repasser 3 selon une variante de réalisation de l'invention qui diffère de celle représentée sur les figures 1 à 13 essentiellement en ce que les extrémités supérieures des parois de barrage 30 sont situées à proximité de la plaque de fermeture 16, et délimitent donc des ouvertures de passage latérales 29 de faibles dimensions. Une telle configuration des parois de barrage 30 permet de limiter encore plus l'introduction de particules de tartre dans les canaux de distribution latéraux 28.The figures 14 and 15 show an iron 3 according to an alternative embodiment of the invention which differs from that shown in the figures 1 to 13 essentially in that the upper ends of the barrier walls 30 are located near the closure plate 16, and therefore define lateral passage openings 29 of small dimensions. Such a configuration of the barrier walls 30 makes it possible to further limit the introduction of scale particles into the lateral distribution channels 28.

Bien entendu, la présente 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 present 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.
