Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des fers à repasser, et en particulier des fers à repasser équipés d'un programme de nettoyage automatique.The present invention relates to the field of irons, and in particular irons equipped with an automatic cleaning program.

Etat de la techniqueState of the art

Un appareil de repassage comprend de façon connue :

  • un fer à repasser comprenant une chambre de vaporisation, une semelle de repassage équipée d'une surface de repassage et d'au moins un orifice de sortie de vapeur débouchant dans la surface de repassage, et un circuit de distribution de vapeur reliant fluidiquement la chambre de vaporisation à l'au moins un orifice de sortie de vapeur et dans lequel est destinée à s'écouler la vapeur produite par la chambre de vaporisation, et
  • une base renfermant un réservoir d'eau et reliée au fer à repasser par un conduit d'acheminement d'eau.
An ironing appliance comprises, in a known manner:
  • an iron comprising a vaporization chamber, an ironing sole fitted with an ironing surface and at least one steam outlet opening opening into the ironing surface, and a steam distribution circuit fluidly connecting the chamber vaporization at at least one vapor outlet orifice and into which the vapor produced by the vaporization chamber is intended to flow, and
  • a base enclosing a water tank and connected to the iron by a water conveyance pipe.

Un tel fer à repasser peut avantageusement comprendre un programme de nettoyage permettant de réaliser un procédé de nettoyage automatique du fer à repasser, et en particulier de la chambre de vaporisation de ce dernier.Such an iron can advantageously comprise a cleaning program making it possible to carry out an automatic cleaning process of the iron, and in particular of the vaporization chamber of the latter.

Un tel procédé de nettoyage consiste notamment à chauffer la chambre de vaporisation à une température prédéterminée, à alimenter la chambre de vaporisation avec un débit d'eau de manière à décoller des particules de tartre des parois intérieures de la chambre de vaporisation, et à collecter les particules de tartre dans une cavité de récupération de tartre prévue dans le fer à repasser.Such a cleaning process consists in particular in heating the vaporization chamber to a predetermined temperature, in supplying the vaporization chamber with a flow of water so as to detach scale particles from the interior walls of the vaporization chamber, and to collect scale particles in a scale recovery cavity provided in the iron.

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 that are closer in time, which can be restrictive for a user.

Il est connu des documents US2018/003377 , WO2015/010968 et WO2017/108440 des appareils de repassage comprenant une cavité de récupération du tartre. Cependant de tels appareils ne comportent pas un programme de nettoyage permettant de réaliser un procédé de nettoyage automatique de la chambre de vaporisation.It is known from the documents US2018 / 003377 , WO2015 / 010968 and WO2017 / 108440 ironing devices comprising a scale recovery cavity. However, such devices do not include a cleaning program making it possible to carry out an automatic cleaning process for the vaporization chamber.

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients. 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 present invention aims to remedy all or part of these drawbacks. 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 de chauffage de la chambre de vaporisation à une température supérieure à 150°C et avantageusement supérieure à 170°C,
  • une deuxième étape d'injection d'eau dans la chambre de vaporisation au moyen de la pompe d'alimentation durant laquelle le débit d'eau injecté dans la chambre de vaporisation est supérieur à un débit d'eau maximal injecté dans la chambre de vaporisation lors d'une étape de repassage, le fer à repasser étant maintenu, durant la deuxième 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, le temps de fonctionnement de la pompe d'alimentation durant la deuxième étape d'injection d'eau étant inférieur au temps nécessaire pour que le volume d'eau injecté par la pompe d'alimentation remonte par le circuit de distribution de vapeur et atteigne au moins un orifice de sortie de vapeur de la semelle de repassage,
  • une troisième étape durant laquelle le fonctionnement de la pompe d'alimentation est interrompu, et
  • une quatrième 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. provided in the ironing soleplate, 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 heating the vaporization chamber to a temperature above 150 ° C and advantageously above 170 ° C,
  • a second step of injecting water into the vaporization chamber by means of the feed pump during which the flow of water injected into the vaporization chamber is greater than a maximum flow of water injected into the vaporization chamber during an ironing step, the iron being maintained, during the second water injection step, in a cleaning position in which the water injected by the feed pump into the vaporization chamber causes scale particles in the scale recovery cavity, the operating time of the feed pump during the second water injection stage being less than the time required for the volume of water injected by the feed pump goes up by the steam distribution circuit and reaches at least one steam outlet opening of the ironing sole,
  • a third step during which the operation of the feed pump is interrupted, and
  • a fourth step of removing the scale collected in the scale recovery cavity by opening the removable cap.

Grâce au choc thermique entre les parois intérieures chaudes de la chambre de vaporisation et l'eau injectée dans cette dernière 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, du fait que la quantité d'eau injectée dans la chambre de vaporisation est supérieure à la quantité d'eau pouvant être vaporisée par la chambre de vaporisation, la température de cette dernière se refroidit rapidement, la semelle de repassage n'ayant plus suffisamment d'énergie pour vaporiser l'eau introduite dans la chambre de vaporisation. L'eau s'accumule donc dans la chambre de vaporisation et dans le circuit de distribution de vapeur, et notamment dans la cavité de récupération de tartre, et entraîne ainsi les particules de tartre dans la cavité de récupération de tartre qui est avantageusement située à l'arrière du fer à repasser.Thanks to the thermal shock between the hot interior walls of the vaporization chamber and the water injected into the latter during the second step, the scale particles present in the vaporization chamber are detached from the interior walls of the vaporization chamber. In addition, because the amount of water injected into the vaporization chamber is greater than the amount of water that can be vaporized by the vaporization chamber, the temperature of the latter cools rapidly, the ironing sole not having plus enough energy to vaporize the water introduced into the vaporization chamber. The water therefore accumulates in the vaporization chamber and in the vapor distribution circuit, and in particular in the scale recovery cavity, and thus entrains the scale particles in the scale recovery cavity which is advantageously located at the back of the iron.

Le temps de fonctionnement de la pompe d'alimentation durant la deuxième étape d'injection d'eau est en particulier inférieur au temps nécessaire pour que le volume d'eau injecté par la pompe d'alimentation remonte par le circuit de distribution et atteigne au moins un orifice de sortie de vapeur de la semelle de repassage afin d'éviter une accumulation d'une partie des particules de tartre décollées à proximité des orifices de sortie de vapeur et donc une obstruction au moins partielle de ces derniers qui nuirait à l'efficacité de repassage et à la durée de vie du fer à repasser.The operating time of the feed pump during the second water injection step is in particular less than the time required for the volume of water injected by the feed pump to rise through the distribution circuit and reach minus one steam outlet orifice of the ironing sole in order to avoid an accumulation of a part of the loose scale particles near the steam outlet openings and therefore at least partial obstruction of the latter which would adversely affect the ironing efficiency and the service life of the iron.

Lors de la deuxième étape d'injection d'eau le fer est maintenu, manuellement ou au moyen d'un support, dans la position de nettoyage selon une orientation adaptée pour que l'eau injectée par la pompe dans la chambre de vaporisation entraine les particules de tartre dans la cavité de récupération du tartre. Bien entendu, cette position de nettoyage pourra varier en fonction de la construction du fer à repasser et en particulier de la position de la cavité de récupération du tartre par rapport à la chambre de vaporisation.During the second water injection step, the iron is maintained, manually or by means of a support, in the cleaning position according to an orientation adapted so that the water injected by the pump into the vaporization chamber causes the scale particles in the scale collection cavity. Of course, this cleaning position may vary depending on the construction of the iron and in particular of the position of the scale recovery cavity relative to the vaporization chamber.

Ainsi, la position de nettoyage correspondra avantageusement à une position du fer à repasser dans laquelle l'eau injectée dans la chambre de vaporisation s'écoule par gravité dans la cavité de récupération du tartre. Cette position pourra être différente ou correspondre, selon la construction du fer à repasser, à la position d'utilisation du fer à repasser dans laquelle la semelle du fer à repasser se trouve disposée horizontalement.Thus, the cleaning position will advantageously correspond to a position of the iron in which the water injected into the vaporization chamber flows by gravity into the scale recovery cavity. This position may be different or correspond, depending on the construction of the iron, to the position of use of the iron in which the sole of the iron is disposed horizontally.

Lorsque l'injection d'eau dans la chambre de vaporisation est stoppée, le fer à repasser remonte en température, et l'eau présente notamment dans la chambre de vaporisation se vaporise. Après vaporisation d'au moins une partie de l'eau contenue dans la chambre de vaporisation et le circuit de distribution de vapeur, le bouchon amovible peut alors être enlevé et la cavité de récupération de tartre peut être vidée des particules de tartre accumulées dans cette dernière.When the injection of water into the vaporization chamber is stopped, the iron rises in temperature, and the water present in particular in the vaporization chamber vaporizes. After vaporization of at least part of the water contained in the vaporization chamber and the vapor distribution circuit, the removable plug can then be removed and the scale recovery cavity can be emptied of the scale particles accumulated in this last.

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 de 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.

Such a method for automatically cleaning the iron 3 can for example comprise:
  • a first step of heating the vaporization chamber 17 to a temperature above 200 ° C,
  • a second step of injecting water into the vaporization chamber 17 by means of the feed pump P, the iron 3 being maintained, during the second step of injecting water, in a cleaning position in in which the water injected by the feed pump P into the vaporization chamber 17 entrains scale particles in the scale recovery cavity 32, the operating time of the feed pump P during the second injection step of water being greater than the time required for the volume of water injected by the feed pump P to at least partially fill the scale recovery cavity 32 but less than the time required for the volume of water injected by the pump supply P rises through the steam distribution circuit 27 and reaches at least one steam outlet 12 of the ironing sole 9, the vaporization chamber 17 being advantageously heated during the second water injection step, for example at a temperature above 200 ° C,

De façon avantageuse, le procédé de nettoyage comprend, préalablement à la deuxième étape, un positionnement du fer à repasser 3 sur l'accessoire de support 37 dont le pied 40 est en position dépliée, de manière à maintenir le fer à repasser dans une position de nettoyage inclinée.Advantageously, the cleaning process comprises, prior to the second step, positioning the iron 3 on the support accessory 37, the foot 40 of which is in the unfolded position, so as to keep the iron in a position inclined cleaning.

Selon un mode de mise en œuvre du procédé de nettoyage, le procédé de nettoyage comprend, préalablement à la cinquième étape, un positionnement du fer à repasser 3 dans une position horizontale. Avantageusement, la cinquième étape est réalisée automatiquement, et par exemple après la détection d'un positionnement du fer à repasser 3 dans une position horizontale à l'aide d'un capteur de position.According to one embodiment of the cleaning method, the cleaning method comprises, prior to the fifth step, positioning the iron 3 in a horizontal position. Advantageously, the fifth step is carried out automatically, and for example after the detection of a positioning of the iron 3 in a horizontal position using a position sensor.

Selon un mode de mise en œuvre du procédé de nettoyage, préalablement à la cinquième étape, la chambre de vaporisation est chauffée à une température supérieure à 200°C. Avantageusement, la chambre de vaporisation 17 est chauffée pendant la cinquième étape d'injection d'eau, par exemple à une température supérieure à 200°C.According to one embodiment of the cleaning process, prior to the fifth step, the vaporization chamber is heated to a temperature above 200 ° C. Advantageously, the vaporization chamber 17 is heated during the fifth water injection step, for example at a temperature above 200 ° C.

Grâce au choc thermique entre les parois intérieures chaudes de la chambre de vaporisation 17 et l'eau injectée dans cette dernière 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. En outre, du fait de la quantité importante d'eau injectée dans la chambre de vaporisation 17 lors de la deuxième étape, la température de cette dernière se refroidit rapidement et la semelle de repassage 9 n'a plus suffisamment d'énergie pour vaporiser l'eau introduite dans la chambre de vaporisation 17. L'eau s'accumule donc dans le circuit de distribution de vapeur 27, et notamment dans la cavité de récupération de tartre 32, et entraîne les particules de tartre, provenant de la chambre de vaporisation 17, dans la cavité de récupération de tartre 32.Thanks to the thermal shock between the hot interior walls of the vaporization chamber 17 and the water injected into the latter during the second step, the scale particles present in the vaporization chamber 17 are detached from the interior walls of the vaporization chamber. 17. In addition, due to the large amount of water injected into the vaporization chamber 17 during the second step, the temperature of the latter cools quickly and the ironing sole 9 no longer has enough energy to. vaporize the water introduced into the vaporization chamber 17. The water therefore accumulates in the steam distribution circuit 27, and in particular in the scale recovery cavity 32, and entrains the scale particles, coming from the chamber spray 17, in the scale recovery cavity 32.

Lorsque l'injection d'eau dans la chambre de vaporisation 17 est stoppée (au début de la troisième étape), la semelle de repassage 9 remonte en température, et l'eau présente notamment dans la chambre de vaporisation 17 et dans le circuit de distribution de vapeur 27 se vaporise. Après vaporisation d'au moins une partie de 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 deuxième étape. De façon avantageuse, le procédé de nettoyage pourrait comprendre l'émission d'un signal sonore et/ou visuel à la fin de la troisième étape afin d'informer l'utilisateur qu'il peut enlever le bouchon amovible 34.When the injection of water into the vaporization chamber 17 is stopped (at the start of the third step), the ironing sole 9 rises in temperature, and the water present in particular in the vaporization chamber 17 and in the heating circuit. steam distribution 27 vaporizes. After vaporization of at least part 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 particles of tartar accumulated in the latter during the second stage. Advantageously, the cleaning method could comprise the emission of an audible and / or visual signal at the end of the third step in order to inform the user that he can remove the removable cap 34.

Lors de la cinquième étape, l'eau injectée dans la chambre de vaporisation 17 remplit au moins partiellement la chambre de vaporisation 17 et la cavité de récupération de tartre 32, et s'écoule dans le circuit de distribution de vapeur 27 avant d'être évacuée à travers les orifices de sortie de vapeur 12 du fer à repasser 3. Une telle circulation de l'eau injectée pendant la cinquième étape entraîne les particules de tartre résiduelles contenues dans le circuit de distribution de vapeur 27 en direction des orifices de sortie de vapeur 12, les particules de tartre provenant de la chambre de vaporisation 17 ayant déjà été évacuées lors de l'étape précédente de vidage de la cavité de récupération de tartre 32, et assure une évacuation de ces particules de tartre résiduelles à travers les orifices de sortie de vapeur 12. Ces dispositions assurent ainsi un nettoyage automatique grandement amélioré du fer à repasser 3.During the fifth step, the water injected into the vaporization chamber 17 at least partially fills the vaporization chamber 17 and the scale recovery cavity 32, and flows into the vapor distribution circuit 27 before being evacuated through the steam outlet orifices 12 of the iron 3. Such a circulation of the water injected during the fifth step entrains the residual scale particles contained in the steam distribution circuit 27 in the direction of the outlet orifices of the iron. steam 12 scale particles coming from the vaporization chamber 17 having already been evacuated during the previous step of emptying the scale recovery cavity 32, and ensures an evacuation of these residual scale particles through the steam outlet orifices 12 These arrangements thus ensure greatly improved automatic cleaning of the iron 3.

Selon un mode de réalisation de l'invention, le fer à repasser 3 pourrait comporter un indicateur d'entartrage avertissant l'utilisateur sur 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 remplissage du réservoir d'eau 5 et sa vitesse 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 scaling indicator warning the user of the need to carry out an automatic cleaning program for the vaporization chamber 17. Such a scaling indicator 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 activation speed can be modulated according to the position of a water hardness indicator .

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.
