Description

La présente divulgation concerne un appareil électroménager comportant un circuit de distribution de vapeur alimentant des trous de sortie de vapeur et se rapporte plus particulièrement à un appareil électroménager, notamment un fer à repasser, dans lequel le circuit de distribution de vapeur comporte au moins un filtre destiné à retenir les particules de tartre.The present disclosure relates to a household appliance comprising a steam distribution circuit supplying steam outlet holes and relates more particularly to a household appliance, in particular an iron, in which the steam distribution circuit comprises at least one filter designed to retain scale particles.

Il est connu, des documents EP 0 711 862 , EP 1 146 164 et EP 1 561 855 , un fer à repasser comprenant une semelle en contact thermique avec un corps chauffant équipé d'une chambre de vaporisation pour la production de vapeur, la vapeur produite par la chambre de vaporisation traversant une grille de filtration disposée à la sortie de la chambre de vaporisation avant d'être transportée vers des trous de sortie de vapeur de la semelle.It is known, documents EP 0 711 862 , EP 1 146 164 and EP 1 561 855 , an iron comprising a soleplate in thermal contact with a heating body equipped with a vaporization chamber for the production of steam, the steam produced by the vaporization chamber passing through a filtration grid arranged at the outlet of the vaporization chamber before being transported to steam outlet holes in the soleplate.

Une telle grille de filtration présente l'avantage de retenir les particules de tartre à l'intérieur de la chambre de vaporisation et permet d'éviter que ces dernières ne s'échappent, en même temps que la vapeur, par les trous de sortie de vapeur de la semelle.Such a filtration grid has the advantage of retaining the scale particles inside the vaporization chamber and makes it possible to prevent the latter from escaping, at the same time as the steam, through the outlet holes of the vaporization chamber. steam from the sole.

Cependant, une telle grille de filtration présente l'inconvénient d'être sujette à l'entartrage. En effet, les gouttelettes d'eau transportées par la vapeur s'évaporent au contact de la grille de filtration, cette dernière se trouvant à une température élevée du fait de son contact thermique avec le corps chauffant, de sorte qu'une pellicule de tartre se forme progressivement sur la grille de filtration, ce qui provoque l'obstruction de la grille de filtration et donc une diminution importante du débit de vapeur au travers des trous de sortie de la semelle.However, such a filtration grid has the disadvantage of being subject to scaling. Indeed, the water droplets transported by the steam evaporate on contact with the filtration grid, the latter being at a high temperature due to its thermal contact with the heating body, so that a film of scale gradually forms on the filtration grid, which causes the obstruction of the filtration grid and therefore a significant reduction in the flow of steam through the outlet holes of the soleplate.

L'invention qui suit vise à pallier ces inconvénients en proposant un appareil électroménager, et notamment un fer à repasser, équipé d'une grille de filtration assurant la rétention des particules de tartre les plus visibles et qui soit peu sensible à l'entartrage.The following invention aims to overcome these drawbacks by proposing a household appliance, and in particular an iron, equipped with a filtration grid ensuring the retention of the most visible scale particles and which is not very sensitive to scaling.

Le but de l'invention est atteint par un appareil électroménager selon la revendication 1.The object of the invention is achieved by a household appliance according to claim 1.

Selon une autre caractéristique de l'invention, le revêtement anti-adhérent est en matériau fluoropolymère.According to another characteristic of the invention, the non-stick coating is made of fluoropolymer material.

Selon une autre caractéristique de l'invention, le revêtement anti-adhérent comprend du PTFE.According to another characteristic of the invention, the non-stick coating comprises PTFE.

Selon une autre caractéristique de l'invention, le filtre est réalisé dans un matériau possédant une effusivité thermique inférieure ou égale à 14000 J/(m2.°C.s1/2).According to another characteristic of the invention, the filter is made of a material having a thermal effusivity less than or equal to 14000 J/(m 2 .°Cs 1/2 ).

Une telle caractéristique permet de limiter la capacité d'échange thermique entre le filtre et les gouttes d'eau pouvant parvenir sur la grille, ce qui permet de limiter la formation de tartre.Such a feature makes it possible to limit the heat exchange capacity between the filter and the drops of water that can reach the grid, which makes it possible to limit the formation of scale.

Selon une autre caractéristique de l'invention, le filtre est constitué par une grille de filtration réalisée en tissu de verre revêtue de PTFE.According to another characteristic of the invention, the filter consists of a filtration grid made of glass fabric coated with PTFE.

Une telle grille de filtration en tissu de verre présente l'avantage de posséder une très faible effusivité thermique de sorte que le risque de former du tartre sur la grille est fortement réduit.Such a glass fabric filtration grid has the advantage of having a very low thermal effusivity so that the risk of forming scale on the grid is greatly reduced.

Selon encore une autre caractéristique de l'invention, le filtre est constitué par une grille de filtration réalisée en acier inox revêtue de PTFE.According to yet another characteristic of the invention, the filter consists of a filtration grid made of stainless steel coated with PTFE.

Une telle grille de filtration en acier inox présente l'avantage de posséder une bonne rigidité qui facilite son montage.Such a stainless steel filtration grid has the advantage of having good rigidity which facilitates its assembly.

Selon encore une autre caractéristique de l'invention, le corps chauffant comprend une fonderie comportant une chambre de vaporisation alimentant le circuit de distribution de vapeur, la chambre de vaporisation étant fermée par une plaque de fermeture rapportée sur la fonderie et étant raccordée au circuit de distribution de vapeur par une ouverture de sortie de vapeur ménagée dans la plaque de fermeture.According to yet another characteristic of the invention, the heating body comprises a foundry comprising a vaporization chamber supplying the steam distribution circuit, the vaporization chamber being closed by a closing plate attached to the foundry and being connected to the dispensing steam through a steam outlet opening in the closure plate.

Selon une autre caractéristique de l'invention, une première grille de filtration est portée par la plaque de fermeture.According to another characteristic of the invention, a first filtration grid is carried by the closing plate.

Selon une autre caractéristique de l'invention, la première grille de filtration est munie d'ouvertures de 1 mm à 2 mm de côté.According to another characteristic of the invention, the first filtration grid is provided with openings of 1 mm to 2 mm on a side.

Selon une autre caractéristique de l'invention, le circuit de distribution de vapeur comporte une deuxième grille de filtration disposée en aval de la première grille de filtration et la deuxième grille de filtration comporte des ouvertures de plus petites tailles que les ouvertures de la première grille de filtration.According to another characteristic of the invention, the steam distribution circuit comprises a second filtration grid arranged downstream of the first filtration grid and the second filtration grid comprises openings of smaller sizes than the openings of the first grid of filtration.

Selon une autre caractéristique de l'invention, les ouvertures de la deuxième grille de filtration mesurent entre 0.2 mm et 0.6 mm de côté.According to another characteristic of the invention, the openings of the second filtration grid measure between 0.2 mm and 0.6 mm on each side.

Une telle grille de filtration avec des ouvertures inférieures à 0.6 mm de côté permet d'éviter que de trop grosses particules de tartre ne soient émises au travers des trous de sortie de vapeur de la semelle. Or, la demanderesse s'est rendue compte que le rejet par la semelle du fer à repasser de petites particules de tartre jusqu'à une taille maximale de 0.6 mm de diamètre était considéré comme acceptable par l'utilisateur.Such a filtration grid with openings less than 0.6 mm on a side makes it possible to prevent excessively large scale particles from being emitted through the steam outlet holes of the soleplate. However, the applicant realized that the rejection by the soleplate of the iron of small particles of tartar up to a maximum size of 0.6 mm in diameter was considered acceptable by the user.

Selon une autre caractéristique de l'invention, le circuit de distribution de la vapeur comporte une troisième grille de filtration disposée en aval des première et deuxième grilles de filtration, cette troisième grille de filtration comportant des ouvertures de plus petites tailles que les ouvertures des première et deuxième grilles de filtration.According to another characteristic of the invention, the steam distribution circuit comprises a third filtration grid arranged downstream of the first and second filtration grids, this third filtration grid comprising openings of smaller sizes than the openings of the first and second filtration grids.

Selon une autre caractéristique de l'invention, les ouvertures de la troisième grille de filtration mesurent entre 0.1 et 0.3 mm de côté.According to another characteristic of the invention, the openings of the third filtration grid measure between 0.1 and 0.3 mm side.

La chambre de vaporisation principale 42 est de type à vaporisation instantanée et comporte à cet effet un fond présentant une multitude de plots pyramidaux permettant d'augmenter la surface d'échange thermique, l'eau du réservoir 30 arrivant au goutte à goutte dans la chambre de vaporisation principale 42 par un orifice 76 de la plaque de fermeture 7 surmonté, de manière connue en soi, d'un boisseau goutte-à-goutte non représenté sur les figures.The main vaporization chamber 42 is of the instantaneous vaporization type and for this purpose comprises a bottom having a multitude of pyramidal studs making it possible to increase the heat exchange surface, the water from the reservoir 30 arriving drop by drop in the chamber. main vaporization 42 through an orifice 76 of the closure plate 7 surmounted, in a manner known per se, by a drip valve not shown in the figures.

Selon un mode particulier de réalisation de l'invention, l'ouverture de sortie de vapeur 70 est équipée d'une première grille de filtration 8 recouverte d'un revêtement anti-adhérent en PTFE (polytétrafluoroéthylène), cette première grille de filtration 8 présentant des ouvertures carrées de 1 mm de côté et comportant une âme préférentiellement réalisée en fil d'inox de 0,4 mm de diamètre ou en tissu de verre réalisé à partir d'un fil tressé de 1 mm de diamètre.According to a particular embodiment of the invention, the steam outlet opening 70 is equipped with a first filtration grid 8 covered with a non-stick coating of PTFE (polytetrafluoroethylene), this first filtration grid 8 having square openings with a side of 1 mm and comprising a core preferably made of stainless steel wire 0.4 mm in diameter or of glass fabric made from a braided wire 1 mm in diameter.

Conformément aux figures 4 et 5, l'ouverture de sortie de vapeur 70 débouche dans un canal de répartition 71 de la vapeur s'étendant transversalement au corps chauffant 4, sur la surface supérieure de la plaque de fermeture 7, le canal de répartition 71 de la vapeur étant délimité latéralement par une nervure 72 faisant saillie sur la plaque de fermeture 7 qui est liée de manière étanche à un capot 73 venant fermer l'extrémité supérieure du canal de répartition 71 de la vapeur.In accordance with figures 4 and 5 , the steam outlet opening 70 opens into a steam distribution channel 71 extending transversely to the heating body 4, on the upper surface of the closure plate 7, the steam distribution channel 71 being delimited laterally by a rib 72 protruding from the closure plate 7 which is connected in leaktight manner to a cover 73 which closes the upper end of the distribution channel 71 of the steam.

La plaque de fermeture 7 comporte également deux ouvertures latérales 74 mettant en communication les deux extrémités du canal de répartition 71 avec une chambre intermédiaire 46 ménagée sur la face supérieure de la fonderie 40, de chaque côté de la chambre de vaporisation principale 42, la chambre intermédiaire 46 s'étendant entre la chambre de vaporisation principale 42 et le canal latéral 44 du circuit de distribution de vapeur.The closure plate 7 also has two side openings 74 putting the two ends of the distribution channel 71 into communication with an intermediate chamber 46 formed on the upper face of the foundry 40, on each side of the main vaporization chamber 42, the chamber intermediate 46 extending between the main vaporization chamber 42 and the side channel 44 of the steam distribution circuit.

Comme on peut le voir sur les figures 3 et 5, la chambre intermédiaire 46 s'étend au dessus de l'élément résistif 5 et est délimitée d'un côté par la cloison 45 entourant la chambre de vaporisation 42 et de l'autre côté par une cloison de séparation 47 bordant les canaux latéraux 44, la cloison de séparation 47 présentant localement une échancrure 47A à son extrémité supérieure permettant le passage de la vapeur de la chambre intermédiaire 46 vers le canal latéral 44 de distribution de vapeur.As can be seen on the figure 3 and 5 , the intermediate chamber 46 extends above the resistive element 5 and is delimited on one side by the partition 45 surrounding the vaporization chamber 42 and on the other side by a partition 47 bordering the side channels 44 , the partition 47 locally presenting a notch 47A at its upper end allowing the passage of steam from the intermediate chamber 46 to the side channel 44 for distributing steam.

De manière préférentielle, chaque canal latéral 44 de distribution de vapeur est muni d'une deuxième grille de filtration 9, cette deuxième grille de filtration 9 reposant sur le fond du canal latéral 44 et formant une barrière filtrante s'étendant au-dessus des orifices 44A traversant la fonderie 40 pour alimenter les trous de sortie de vapeur 20 de la semelle, la deuxième grille de filtration 9 présentant des ouvertures de plus petites tailles que la taille des ouvertures de la première grille de filtration 8 afin de retenir les particules de tartre de plus petit diamètre ayant réussi à traverser la première grille de filtration 8.Preferably, each side channel 44 for distributing steam is provided with a second filtration grid 9, this second filtration grid 9 resting on the bottom of the side channel 44 and forming a filtering barrier extending above the orifices 44A passing through the foundry 40 to supply the steam outlet holes 20 of the soleplate, the second filtration grid 9 having openings of smaller sizes than the size of the openings of the first filtration grid 8 in order to retain the scale particles of smaller diameter having succeeded in passing through the first filtration grid 8.

A titre d'exemple, la deuxième grille de filtration 9 comporte des ouvertures carrées mesurant de l'ordre de 0.4 mm de côté, et est avantageusement réalisée en fil d'inox de 0.4 mm de diamètre recouvert d'un revêtement anti-adhérent en PTFE.By way of example, the second filtration grid 9 comprises square openings measuring the order of 0.4 mm on a side, and is advantageously made of stainless steel wire 0.4 mm in diameter covered with a non-stick coating in PTFE.

Conformément aux figures 2 et 3, la chambre de survapeur 43 est placée juste devant la chambre de vaporisation principale 42, de manière à s'étendre au dessus de l'élément résistif 5 en forme de fer à cheval, et est fermée à son extrémité supérieure par un couvercle 43A comprenant un orifice d'injection d'eau 43B relié, de manière connue en soi, à une pompe manuelle à piston non représentée sur les figures.In accordance with figure 2 and 3 , the supervapor chamber 43 is placed just in front of the main vaporization chamber 42, so as to extend above the resistive element 5 in the shape of a horseshoe, and is closed at its upper end by a cover 43A comprising a water injection orifice 43B connected, in a manner known per se, to a manual piston pump not shown in the figures.

La vapeur produite par la chambre de survapeur 43 est diffusée dans une cavité 48 ménagée à l'avant de la fonderie 40 par des conduits bordant la chambre de survapeur, la cavité 48 comprenant des orifices 48A traversant la fonderie 40 pour alimenter un nombre restreint de trous de sortie de vapeur 20 disposés au niveau de la pointe avant de la semelle 2 et étant séparée des canaux latéraux 44 du circuit de distribution de vapeur par des cloisons 75, représentées en pointillés sur la figure 3, faisant saillie sous la plaque de fermeture 7.The steam produced by the booster chamber 43 is diffused into a cavity 48 made at the front of the foundry 40 by conduits bordering the booster chamber, the cavity 48 comprising orifices 48A passing through the foundry 40 to supply a limited number of steam outlet holes 20 arranged at the level of the front tip of the soleplate 2 and being separated from the side channels 44 of the steam distribution circuit by partitions 75, shown in dotted lines on the picture 3 , protruding under the closing plate 7.

La chambre de survapeur 43 est également équipée d'une grille de filtration 10 destinée à retenir les particules de tartre transportées par la vapeur, cette grille de filtration 10 étant préférentiellement constituée par une tôle d'inox recouverte d'un revêtement anti-adhérent en PTFE et comportant des ouvertures circulaires présentant un diamètre de l'ordre de 0.6 mm de diamètre.The supersteam chamber 43 is also equipped with a filtration grid 10 intended to retain the scale particles transported by the steam, this filtration grid 10 preferably being constituted by a stainless steel sheet covered with a non-stick coating in PTFE and comprising circular openings having a diameter of the order of 0.6 mm in diameter.

La figure 6 illustre le cheminement de la vapeur produite par la chambre de vaporisation principale 42 dans le fer à repasser ainsi réalisé.The figure 6 illustrates the path of the steam produced by the main vaporization chamber 42 in the iron thus produced.

Conformément à cette figure, la vapeur produite par la chambre de vaporisation principale 42 s'échappe verticalement au travers de l'ouverture de sortie de vapeur 70 équipée de la première grille de filtration 8 de sorte que les particules de tartre de plus de 1 mm de diamètre transportées par la vapeur sont stoppées par la première grille de filtration 8 et retombent, par gravité, dans la chambre de vaporisation principale 42.In accordance with this figure, the steam produced by the main vaporization chamber 42 escapes vertically through the steam outlet opening 70 equipped with the first filtration grid 8 so that the scale particles of more than 1 mm in diameter transported by the steam are stopped by the first filtration grid 8 and fall, by gravity, into the main vaporization chamber 42.

La vapeur filtrée ayant traversé la première grille de filtration 8 s'écoule alors horizontalement dans le canal de répartition 71 de vapeur, puis verticalement au travers des ouvertures latérales 74 pour parvenir dans la chambre intermédiaire 46 de la fonderie 40 dans laquelle les éventuelles gouttes d'eau transportées par la vapeur se trouvent vaporisées, la vapeur surchauffée s'échappant ensuite par les échancrures 47A des cloisons de séparation 47 en direction de canaux latéraux 44 du circuit de distribution de la vapeur. La vapeur présente dans les canaux latéraux 44 s'écoule alors au travers de la deuxième grille de filtration 9 puis verticalement dans les orifices 44A traversant de la fonderie 40 avant d'être diffusée par les trous de sortie de vapeur 20 de la semelle.The filtered steam having passed through the first filtration grid 8 then flows horizontally into the steam distribution channel 71, then vertically through the side openings 74 to reach the intermediate chamber 46 of the foundry 40 in which any drops of The water transported by the steam is vaporized, the superheated steam then escaping through the notches 47A of the partition walls 47 in the direction of the side channels 44 of the steam distribution circuit. The steam present in the side channels 44 then flows through the second filtration grid 9 then vertically into the orifices 44A passing through the foundry 40 before being diffused through the steam outlet holes 20 of the soleplate.

Lorsque la vapeur traverse la deuxième grille de filtration 9, les éventuelles particules de tartre transportées par la vapeur présentant un diamètre supérieur à 0.4 mm sont stoppées en amont de la deuxième grille de filtration 9 de sorte que ces particules de tartres, présentant un diamètre compris entre 0.4 et 1 mm, se trouvent stockées dans la partie du circuit de vapeur s'étendant entre la première grille de filtration 8 et la seconde grille de filtration 9.When the steam passes through the second filtration grid 9, any scale particles transported by the steam having a diameter greater than 0.4 mm are stopped upstream of the second filtration grid 9 so that these scale particles, having a diameter of between between 0.4 and 1 mm, are stored in the part of the vapor circuit extending between the first filtration grid 8 and the second filtration grid 9.

Le fer à repasser à vapeur ainsi réalisé présente l'avantage d'être équipé d'un dispositif de filtration de la vapeur assurant la rétention, à l'intérieur du fer à repasser, des particules de tartre présentant un diamètre supérieur à 0.4 mm lors de la production de vapeur à partir de la chambre de vaporisation 42 principale de sorte que les particules sortant par les trous de sortie de vapeur 20 sont sensiblement invisibles par l'utilisateur.The steam iron thus produced has the advantage of being equipped with a steam filtration device ensuring the retention, inside the iron, of scale particles having a diameter greater than 0.4 mm during steam production from the main vaporization chamber 42 so that the particles exiting through the steam outlet holes 20 are substantially invisible to the user.

En particulier, le dispositif de filtration ainsi réalisé présente l'avantage de posséder des grilles de filtration revêtues d'un revêtement anti-adhérent permettant d'éviter que le tartre n'adhère à la grille de filtration et ne bouche la grille de filtration après quelques mois d'utilisation. De plus, la faible effusivité du matériau utilisé pour la grille de filtration présente l'avantage d'éviter une évaporation importante des gouttes d'eau parvenant au contact de la grille de filtration surchauffée, ce qui permet de limiter la formation de tartre sur la grille de filtration.In particular, the filtration device thus produced has the advantage of having filtration grids coated with a non-stick coating making it possible to prevent scale from adhering to the filtration grid and clogging the filtration grid after few months of use. In addition, the low effusivity of the material used for the filtration grid has the advantage of avoiding significant evaporation of the drops of water coming into contact with the overheated filtration grid, which makes it possible to limit the formation of scale on the filter grid.

Enfin, l'usage de deux grilles de filtration successives sur le cheminement de la vapeur, avec des ouvertures calibrées de plus petite taille sur la deuxième grille de filtration traversée par la vapeur, permet d'éviter que la deuxième grille de filtration ne soit trop rapidement bouchée par de grosses particules de tartre. En effet, grâce à ce dispositif de filtration, les plus grosses particules de tartre sont maintenues dans la chambre de vaporisation principale par la première grille de filtration et seule une plus faible quantité de particules de tartre de plus petite taille peut parvenir jusqu'à la deuxième grille de filtration.Finally, the use of two successive filtration grids on the path of the steam, with smaller calibrated openings on the second filtration grid through which the steam passes, makes it possible to prevent the second filtration grid from being too quickly clogged with large scale particles. In fact, thanks to this filtration device, the largest scale particles are kept in the main vaporization chamber by the first filtration grid and only a smaller quantity of scale particles of smaller size can reach the second filtration grid.

Ainsi, un tel fer à repasser ne risque pas de se trouver rapidement inutilisable du fait du colmatage de la grille de filtration par le tartre, mais peut être utilisé plusieurs années.Thus, such an iron does not run the risk of quickly becoming unusable due to clogging of the filtration grid by scale, but can be used for several years.

On résout donc, par ce dispositif de filtration, le problème de rejets de particules de tartres qui tachent le linge lors du repassage et qui est perçu très défavorablement par l'utilisateur.This filtration device therefore solves the problem of the release of scale particles which stain the linen during ironing and which is perceived very unfavorably by the user.

Un tel appareil présente également l'avantage d'assurer la rétention des plus grosses particules de tartre lors de l'utilisation de la chambre de survapeur, la grille de filtration associée à cette chambre permettant d'éviter que des particules de tartre présentant un diamètre supérieur à 0.6 mm ne soient éjectées au travers des trous de sortie de vapeur de la semelle.Such a device also has the advantage of ensuring the retention of the largest scale particles when using the supervapor chamber, the filtration grid associated with this chamber making it possible to prevent scale particles having a diameter greater than 0.6 mm are ejected through the steam outlet holes in the soleplate.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation précédemment 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 previously 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 illustrée sur la figure 7, la deuxième grille de filtration 9 pourra être fixée sur la plaque de fermeture 7 et venir se positionner dans la partie supérieure des canaux latéraux 44 du circuit de distribution de la vapeur. Une telle variante de réalisation présente l'avantage de faciliter l'assemblage du corps chauffant, les première et deuxième grilles de filtration 8, 9 pouvant être positionnées sur la plaque de fermeture 7 dans une étape préalable à l'assemblage de la plaque de fermeture sur la fonderie.Thus, in a variant embodiment illustrated in the figure 7 , the second filtration grid 9 can be fixed on the closure plate 7 and be positioned in the upper part of the side channels 44 of the steam distribution circuit. Such a variant has the advantage of facilitating the assembly of the heating body, the first and second filtration grids 8, 9 being able to be positioned on the closure plate 7 in a step prior to the assembly of the closure plate on the foundry.

Dans une autre variante de réalisation non représentée, la première grille de filtration pourra être fixée sur la plaque de fermeture au niveau de chacune des ouvertures latérales du canal de répartition de la vapeur, une telle variante de réalisation présentant l'avantage d'éloigner la première grille de filtration de la chambre de vaporisation principale de sorte que la probabilité qu'une gouttelette d'eau non vaporisée parvienne sur la première grille de filtration est réduite.In another variant embodiment, not shown, the first filtration grid may be fixed to the closure plate at the level of each of the side openings of the steam distribution channel, such a variant embodiment having the advantage of keeping the first filter screen of the main vaporization chamber so that the probability of an unvaporized water droplet reaching the first filter screen is reduced.

Dans une autre variante de réalisation de l'invention, la taille des ouvertures des première et deuxième grilles de filtration pourra être modifiée. A titre d'exemple, la taille des ouvertures de la première grille de filtration sera préférentiellement comprise entre 1 mm et 2 mm de côté tandis que la taille des ouvertures de la deuxième grille de filtration sera préférentiellement comprise entre 0.2 mm et 0.6 mm de côté.In another alternative embodiment of the invention, the size of the openings of the first and second filtration grids may be modified. By way of example, the size of the openings of the first filtration grid will preferably be between 1 mm and 2 mm on a side while the size of the openings of the second filtration grid will preferably be between 0.2 mm and 0.6 mm on a side .

Dans une autre variante de réalisation non représentée, l'appareil pourra comporter une troisième grille de filtration disposée sur le circuit de distribution de la vapeur, en aval des première et deuxième grilles de filtration, cette troisième grille de filtration comportant des ouvertures de plus petite taille que celles des ouvertures des première et deuxième grilles de filtration. A titre d'exemple, les ouvertures de la troisième grille de filtration mesureront entre 0.1 mm et 0.3 mm de côté, de manière à ce que les particules pouvant passer au travers de cette troisième grille soient invisibles à l'oeil nu.In another variant embodiment, not shown, the device may comprise a third filtration grid arranged on the steam distribution circuit, downstream of the first and second filtration grids, this third filtration grid comprising openings of smaller size than those of the openings of the first and second filtration grids. By way of example, the openings of the third filtration grid will measure between 0.1 mm and 0.3 mm on each side, so that the particles which can pass through this third grid are invisible to the naked eye.
