Description

La présente invention concerne un générateur de vapeur pour fer à repasser.The present invention relates to a generator steam for iron.

Les générateurs de vapeur comprennent un réservoir d'eau, des moyens pour chauffer cette eau, ce réservoir comportant à sa partie supérieure un orifice de sortie de vapeur destiné à être relié au fer à repasser et une ouverture de remplissage d'eau (voir par exemple le document FR-A-1083733).The steam generators include a water tank, means for heating this water, this tank having at its upper part an orifice steam outlet intended to be connected to the iron iron and a water filling opening (see for example document FR-A-1083733).

On sait que lors du chauffage de l'eau contenue dans le réservoir du générateur de vapeur, il se forme dans cette eau des particules de tartre ou de calcaire.We know that when heating the water contained in the steam generator tank it forms in this water particles of tartar or limestone.

Les particules de tartre peuvent se déposer et obstruer complètement certaines parties sensibles du générateur de vapeur telles que l'électro-vanne qui commande le passage de la vapeur vers le fer à repasser ou le dispositif de sécurité de pression généralement contenu dans le bouchon de fermeture de l'ouverture de remplissage d'eau du réservoir et qui protège le générateur contre les surpressions de vapeur.Tartar particles can settle and completely obstruct certain sensitive parts of the steam generator such as the solenoid valve which controls the passage of steam to the iron or the pressure safety device generally contained in the closure cap of the opening of filling the tank with water and which protects the generator against overpressure of steam.

Le but de la présente invention est de remédier à l'inconvénient ci-dessus.The object of the present invention is to remedy to the above drawback.

L'invention vise ainsi un générateur de vapeur pour fer à repasser comprenant un réservoir d'eau, des moyens pour chauffer cette eau, ce réservoir comportant à sa partie supérieure un orifice de sortie de vapeur destiné à être relié au fer à repasser et une ouverture de remplissage d'eau.The invention thus relates to a steam generator for iron comprising a water tank, means for heating this water, this tank comprising at its upper part a steam outlet intended to be connected to the iron and an opening filling water.

Ce générateur de vapeur comprend en outre, en amont de l'orifice de sortie, un filtre destiné à retenir les particules de tartre formées lors du chauffage de l'eau et susceptibles d'être entraínées par la vapeur vers l'orifice de sortie de la vapeur.This steam generator further comprises, in upstream of the outlet, a filter intended for retain the tartar particles formed during water heating and likely to be driven by steam to the steam outlet.

Suivant l'invention, le générateur de vapeur est caractérisé en ce que le filtre est placé dans l'ouverture de remplissage d'eau sous le bouchon qui ferme cette ouverture.According to the invention, the steam generator is characterized in that the filter is placed in the water filling opening under the cap which close this opening.

De ce fait, les parties sensibles du fer ne risquent pas d'être obstruées par un dépôt de tartre ou de calcaire.Therefore, the sensitive parts of the iron do not risk of being blocked by a lime scale deposit or of limestone.

De plus, le filtre est visible et accessible après enlèvement du bouchon, pour être nettoyé ou remplacé.In addition, the filter is visible and accessible after removing the cap, to be cleaned or replaced.

Dans le cas où le dispositif de sécurité de pression est disposé dans le bouchon, ce dispositif de sécurité de pression est également protégé par le filtre contre les risques d'obstruction dus au tartre.In the event that the safety device pressure is placed in the cap, this pressure safety is also protected by the filter against the risk of obstruction due to tartar.

Dans une version avantageuse de l'invention, le filtre est disposé en amont de l'électro-vanne qui commande le passage de la vapeur vers le fer à repasser.In an advantageous version of the invention, the filter is placed upstream of the solenoid valve which controls the passage of steam to the iron.

L'électro-vanne se trouve ainsi efficacement protégée contre les dépôts de tartre.The solenoid valve is thus efficiently located protected against scale deposits.

De préférence, le filtre est porté par ledit bouchon.Preferably, the filter is carried by said plug.

Ainsi, en enlevant le bouchon, on enlève également le filtre, ce qui permet d'examiner son état et de le nettoyer facilement.So, by removing the cap, we remove also the filter, which allows to examine its state and clean it easily.

D'autres particularités et avantages de l'invention apparaítront encore dans la description ci-après.Other features and advantages of the invention will appear further in the description below.

Aux dessins annexés, donnés à titre d'exemples non limitatifs:

  • la figure 1 est une vue schématique en coupe partielle d'un générateur de vapeur équipé d'un filtre,
  • la figure 2 est une vue schématique analogue à la figure 1 et illustrant un autre mode de réalisation de l'invention.
  • la figure 3 est une vue schématique analogue aux figures 1 et 2, illustrant un autre mode de réalisation de l'invention.
In the appended drawings, given by way of nonlimiting examples:
  • FIG. 1 is a schematic view in partial section of a steam generator equipped with a filter,
  • Figure 2 is a schematic view similar to Figure 1 and illustrating another embodiment of the invention.
  • Figure 3 is a schematic view similar to Figures 1 and 2, illustrating another embodiment of the invention.

Dans la réalisation de la figure 1, le générateur de vapeur pour fer à repasser comprend un réservoir d'eau 1, une résistance électrique (non représentée) pour chauffer cette eau, ce réservoir 1 comportant à sa partie supérieure un orifice 2 de sortie de vapeur destiné à être relié à un fer à repasser et une ouverture 3 de remplissage d'eau.In the embodiment of FIG. 1, the steam generator for iron includes a water tank 1, an electrical resistance (not shown) to heat this water, this tank 1 comprising at its upper part an outlet orifice 2 steam intended to be connected to an iron and a water filling opening 3.

Conformément à l'invention, le générateur comprend en amont de l'orifice de sortie 2, au moins un filtre 4 destiné à retenir les particules de tartre formées lors du chauffage de l'eau et susceptibles d'être entraínées par la vapeur vers l'orifice de sortie 2.According to the invention, the generator comprises upstream of the outlet orifice 2, at least one filter 4 intended to retain the particles of tartar formed during water heating and susceptible to be entrained by steam to the outlet 2.

Dans l'exemple représenté, le filtre 4 est placé dans l'ouverture 3 de remplissage d'eau sous le bouchon 5 qui ferme cette ouverture 3. Le bouchon 5 peut renfermer un dispositif de sécurité de pression.In the example shown, filter 4 is placed in the water filling opening 3 under the cap 5 which closes this opening 3. The plug 5 can contain a pressure safety device.

Par ailleurs, le filtre 4 est disposé en amont de l'électro-vanne 6 qui commande le passage de la vapeur vers le fer à repasser.Furthermore, the filter 4 is arranged upstream of the solenoid valve 6 which controls the passage of the steam to the iron.

Dans le cas de la figure 1, le filtre 4 est porté par le bouchon 5.In the case of FIG. 1, the filter 4 is carried by the cap 5.

Par ailleurs, le bouchon 5 comporte un embout 7 qui est vissé dans l'ouverture 3 de remplissage d'eau et comporte un passage axial 8 qui communique avec l'intérieur du réservoir 1. La partie inférieure de l'embout comporte deux filtres 4, 4a s'étendant perpendiculairement à l'axe du passage axial 8. La surface extérieure de l'embout 7 comporte une gorge annulaire 9 communiquant avec le passage 8 par une ou plusieurs ouvertures 10 et avec le conduit 2 de sortie de la vapeur.Furthermore, the plug 5 has a tip 7 which is screwed into the water filling opening 3 and has an axial passage 8 which communicates with inside the tank 1. The lower part of the nozzle has two filters 4, 4a extending perpendicular to the axis of the axial passage 8. The outer surface of the end piece 7 has a groove annular 9 communicating with passage 8 by one or several openings 10 and with the outlet duct 2 steam.

Les deux filtres 4, 4a sont disposés l'un au dessus de l'autre et fixés à l'intérieur de l'embout 7 par des moyens tels que des circlips.The two filters 4, 4a are arranged one at the above each other and fixed inside the end piece 7 by means such as circlips.

Dans l'exemple de la figure 2, le filtre 4b est espacé du bouchon 5 et est fixé à l'extrémité inférieure 3a de l'ouverture 3 de remplissage d'eau.In the example in Figure 2, the filter 4b is spaced from plug 5 and is attached to the lower end 3a of the opening 3 for filling the water.

De plus, dans cet exemple, le filtre 4b comporte une anse 11 de préhension faisant saillie vers le haut de l'ouverture de remplissage 3.Furthermore, in this example, the filter 4b comprises a gripping handle 11 projecting upwards filling opening 3.

Comme dans l'exemple de la figure 1, le bouchon 5 comporte un embout creux 7a vissé dans l'ouverture 3 et l'anse 11 du filtre 4b fait saillie dans la partie creuse 10a de l'embout 7a.As in the example in Figure 1, the plug 5 has a hollow endpiece 7a screwed into the opening 3 and the loop 11 of the filter 4b protrudes in the part hollow 10a of the nozzle 7a.

Dans l'exemple de la figure 3, le filtre 4c est espacé du bouchon 5 et est fixé à l'extrémité inférieure 3a de l'ouverture 3 de remplissage d'eau.In the example of Figure 3, the filter 4c is spaced from plug 5 and is attached to the lower end 3a of the opening 3 for filling the water.

Ce filtre est amovible grâce à une anse de préhension 11a faisant saillie vers le haut de l'ouverture 3 de remplissage.This filter is removable thanks to a handle of grip 11a protruding upwards the filling opening 3.

Par ailleurs, comme dans l'exemple de la figure 1, le bouchon 5 comporte un embout 7 qui est vissé dans l'ouverture 3 de remplissage et comporte un passage axial 8 qui communique avec l'intérieur du réservoir 1. La partie inférieure de l'embout 7 comporte un filtre 4d s'étendant perpendiculairement à l'axe du passage axial 8. Le filtre 4d, solidaire du bouchon, est visible et démontable pour le nettoyer facilement.Furthermore, as in the example in the figure 1, the plug 5 has a tip 7 which is screwed into the filling opening 3 and has a passage axial 8 which communicates with the interior of the tank 1. The lower part of the nozzle 7 has a 4d filter extending perpendicular to the axis of the axial passage 8. The 4d filter, secured to the cap, is visible and removable for easy cleaning.

Les filtres 4, 4a, 4b, 4c, 4d peuvent être un grillage ou une feuille perforée en métal de préférence en acier inoxydable ou matière plastique, ou tout autre filtre connu.Filters 4, 4a, 4b, 4c, 4d can be a wire mesh or a perforated sheet of metal preferably stainless steel or plastic, or any other known filter.

Lors du fonctionnement du générateur de vapeur, l'eau contenue dans le réservoir 1 est chauffée jusqu'à ébullition. De fines particules de tartre provenant des éléments minéraux contenus dans l'eau se déposent à la surface de cette eau et sont entraínées par la vapeur vers la sortie 2 qui conduit au fer à repasser. When the steam generator is running, the water in tank 1 is heated to boiling. Fine particles of tartar from mineral elements contained in water are deposited at the surface of this water and are entrained by steam towards exit 2 which leads to the iron.

Dans les trois exemples de réalisations, le sens de passage de la vapeur est schématisé par la flèche F.In the three examples of realizations, the meaning steam passage is shown schematically by the arrow F.

Les fines particules de tartre sont retenues par le ou les filtres 4, 4a, 4b, 4c, 4d. Lorsque le réservoir 1 doit être rempli d'eau (ce qui doit être fait périodiquement), l'utilisateur dévisse le bouchon 5.The fine particles of tartar are retained by the filter (s) 4, 4a, 4b, 4c, 4d. When the tank 1 must be filled with water (which must be done periodically), the user unscrews the cap 5.

Dans le cas de la réalisation de la figure 1, les filtres 4, 4a portés par le bouchon 5 s'enlèvent en même temps que ce dernier.In the case of the embodiment of FIG. 1, the filters 4, 4a carried by the plug 5 are removed in same time as the latter.

L'utilisateur peut alors nettoyer les filtres 4, 4a s'ils sont partiellement colmatés par du calcaire.The user can then clean the filters 4, 4a if they are partially clogged with limestone.

L'électro-vanne 6 ainsi que le dispositif de sécurité de pression contenu dans le bouchon 5 sont ainsi protégés contre tout risque d'obstruction par du calcaire.The solenoid valve 6 as well as the device pressure safety contained in the cap 5 are thus protected against any risk of obstruction by limestone.

De même, aucun dépôt de calcaire ne peut avoir lieu dans le fer à repasser relié à la sortie 6a de l'électro-vanne 6.Likewise, no limestone deposit can have place in the iron connected to exit 6a of the solenoid valve 6.

Dans le cas de l'exemple de la figure 2, après enlèvement du bouchon 5, le filtre 4b peut être enlevé facilement, en vue de son nettoyage grâce à l'anse 11.In the case of the example in Figure 2, after removal of plug 5, filter 4b can be removed easily, for cleaning thanks to the handle 11.

De même, dans l'exemple de réalisation de la figure 3, les filtres 4c, 4d peuvent être démontés facilement après enlèvement du bouchon 5.Similarly, in the embodiment of the Figure 3, the filters 4c, 4d can be removed easily after removing the cap 5.

Dans le cas de l'exemple de la figure 1, l'espace compris entre les deux filtres 4,4a peut éventuellement être rempli par des grains ou des fibres d'une matière filtrante ou traitante.In the case of the example in Figure 1, the space between the two filters 4,4a can possibly be filled with grains or fibers a filtering or treating material.

Il en est de même dans le cas de l'exemple de la figure 3.The same is true in the case of the example of the figure 3.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus et des variantes d'exécution peuvent y être apportées.Of course, the invention is not limited to embodiments described above and variants can be made.

On peut notamment combiner de différentes manières plusieurs filtres, amovibles ou non, les uns étant portés par le bouchon fermant l'ouverture de remplissage, les autres espacés dudit bouchon.We can in particular combine different ways several filters, removable or not, each being carried by the plug closing the opening of filling, the other spaces of said plug.
