La présente invention concerne les fers à repasser a vapeur comprenant un corps renfermant un réservoir surmontant un corps chauffant et se rapporte plus particulièrement à un fer à repasser comprenant un réservoir muni d'un dispositif de sécurité contre les surpressions, ces surpressions pouvant notamment être engendrées par une élévation de la température du réservoir lorsque le boisseau d'alimentation de la chambre de vaporisation et l'orifice de remplissage du réservoir sont fermés.The present invention relates to steam irons comprising a body enclosing a tank surmounting a heating body and relates more particularly to an iron comprising a tank provided with a safety device against overpressures, these overpressures can in particular be generated by raising the temperature of the reservoir when the supply sluice of the vaporization chamber and the filling orifice of the reservoir are closed.

Il est connu, du document GB 597 209 , un fer à repasser à vapeur comportant un corps renfermant un réservoir d'eau surmontant un corps chauffant et un dispositif d'évent permettant d'éviter que la pression dans le réservoir ne soit trop importante. Dans ce document, la sortie de l'évent est munie d'un déflecteur pour éviter que la vapeur générée dans le réservoir ne soit projetée sur les mains.It is known from the document GB 597,209 , a steam iron having a body enclosing a water tank surmounting a heating body and a vent device to prevent the pressure in the tank is too important. In this document, the outlet of the vent is provided with a deflector to prevent the steam generated in the tank is projected on the hands.

Cependant, un tel évent présente l'inconvénient de permettre à de l'eau du réservoir de s'échapper par l'évent lors du repassage. De plus, dans le cas d'une élévation de la température dans le réservoir, les projections de vapeur et d'eau par l'évent restent dangereuses et sont mal perçues par l'utilisateur.However, such a vent has the disadvantage of allowing water from the tank to escape through the vent during ironing. In addition, in the case of a rise in the temperature in the tank, the vapor and water projections through the vent remain dangerous and are poorly perceived by the user.

Ainsi, le but de la présente invention est de remédier à ces inconvénients en proposant un fer à repasser comportant un réservoir muni d'un dispositif de sécurité contre les suppressions qui soit simple et économique à réaliser. Un autre but de la présente invention est de proposer un dispositif de sécurité qui laisse s'échapper la vapeur en direction de la chambre de vaporisation lorsque le réservoir est en surpression de manière à permettre l'évaporation des éventuelles gouttelettes d'eau et l'évacuation de la vapeur par les trous de la semelle.Thus, the object of the present invention is to overcome these disadvantages by providing an iron with a reservoir provided with a safety device against deletions that is simple and economical to achieve.

Une telle caractéristique permet, par un moyen simple et peu coûteux, de diffuser la vapeur du réservoir en surpression en direction de la chambre de vaporisation de sorte que la vapeur s'échappe progressivement par les trous de sortie de vapeur de la semelle, sans risque de projection de gouttelettes d'eau bouillante, ces dernières étant vaporisées dans la chambre de vaporisation.Such a characteristic makes it possible, by a simple and inexpensive means, to diffuse the steam from the tank under overpressure towards the vaporization chamber so that the vapor escapes progressively through the steam outlet holes of the sole, without risk. projection of droplets of boiling water, the latter being vaporized in the vaporization chamber.

Selon une autre caractéristique de l'invention, le circuit d'alimentation relie une pompe, ou un boisseau goutte à goutte, à la chambre de vaporisation.According to another characteristic of the invention, the supply circuit connects a pump, or a plug drop, to the vaporization chamber.

Selon une autre caractéristique de l'invention, le circuit d'alimentation relie une pompe manuelle à la chambre de vaporisation, la pompe étant équipée d'un clapet anti-retour, l'ouverture étant disposée en aval du clapet anti-retour.According to another characteristic of the invention, the supply circuit connects a manual pump to the vaporization chamber, the pump being equipped with a non-return valve, the opening being disposed downstream of the non-return valve.

Selon une autre caractéristique de l'invention, l'élément comportant l'ouverture obturée par le clapet est un manchon de connexion de la sortie de la pompe.According to another characteristic of the invention, the element comprising the opening closed by the valve is a connecting sleeve of the output of the pump.

Selon une autre caractéristique de l'invention, le clapet est formé par une paroi capable de se déformer élastiquement lorsque la pression régnant à l'intérieur du réservoir atteint la valeur prédéterminée.According to another characteristic of the invention, the valve is formed by a wall capable of elastically deforming when the pressure inside the reservoir reaches the predetermined value.

Selon encore une autre caractéristique de l'invention, la paroi est portée par un corps en caoutchouc.According to yet another characteristic of the invention, the wall is carried by a rubber body.

Selon une autre caractéristique de l'invention, le corps en caoutchouc est un joint d'étanchéité.According to another characteristic of the invention, the rubber body is a seal.

Pour faciliter la lecture des dessins, les mêmes éléments portent les mêmes références d'une figure à l'autre.Only the elements necessary for the understanding of the invention have been represented. To facilitate the reading of the drawings, the same elements bear the same references from one figure to another.

Les figures 1 et 2 représentent un fer à vapeur comprenant un boîtier 1 muni d'une poignée de préhension 1A, le boîtier 1 surmontant une semelle 2 en conduction thermique avec un corps chauffant 3 dont la température est régulée par un thermostat 4.The figures 1 and 2 represent a steam iron comprising a housing 1 provided with a handle 1A, the housing 1 surmounting a sole 2 in thermal conduction with a heating body 3 whose temperature is regulated by a thermostat 4.

Conformément à ces figures, le boîtier 1 renferme classiquement un réservoir 5 servant à alimenter une première chambre de vaporisation 6 au travers d'un boisseau goutte à goutte, non représenté sur les figures, la vapeur ainsi produite s'échappant au travers d'orifices de sortie 2A de la semelle.According to these figures, the casing 1 typically encloses a reservoir 5 serving to supply a first vaporization chamber 6 through a drip-shaped plug, not shown in the figures, the vapor thus produced escaping through orifices. 2A output of the sole.

Le réservoir 5 est muni d'un orifice de remplissage qui est masqué par une trappe 7 disposée sur la face avant du fer assurant une fermeture étanche de l'orifice de remplissage, la trappe 7 pouvant basculer autour d'un axe 7A vers une position ouverte, représentée en pointillés sur la figure 1, pour permettre le remplissage du réservoir 5.The tank 5 is provided with a filling orifice which is masked by a hatch 7 disposed on the front face of the iron ensuring a tight closure of the filling orifice, the hatch 7 being able to swing about an axis 7A towards a position open, represented in dotted lines on the figure 1 , to allow the filling of the tank 5.

Le fer comporte, de manière connue en soi, une première pompe manuelle 8, masquée sur les figures 1 et 2, permettant d'envoyer de l'eau du réservoir 5 en direction d'une buse de pulvérisation 8A disposée sur la face avant du fer, cette pompe 8 étant actionnée par l'utilisateur au moyen d'un bouton, non visible sur les figures, disposé devant la poignée 1A.The iron comprises, in a manner known per se, a first manual pump 8, masked on the figures 1 and 2 , for sending water from the tank 5 towards a spray nozzle 8A disposed on the front face of the iron, this pump 8 being actuated by the user by means of a button, not visible in the figures, arranged in front of the handle 1A.

Le fer comporte également une seconde pompe manuelle 9 alimentée en eau du réservoir 5 et actionnable par l'utilisateur au moyen d'un bouton 9A, chaque impulsion sur le bouton 9A permettant d'envoyer un volume d'eau prédéterminé dans une seconde chambre de vaporisation 11 permettant la production d'un surplus de vapeur lors du repassage.The iron also comprises a second manual pump 9 supplied with water from the reservoir 5 and operable by the user by means of a button 9A, each pulse on the button 9A for sending a predetermined volume of water into a second chamber of vaporization 11 allowing the production of a surplus of steam during ironing.

Conformément aux figures 3 et 4, ces deux pompes manuelles 8, 9 sont portées par un même corps 10 disposé dans l'enceinte du réservoir 5, ce corps 10 comportant deux cylindres en parallèle dans lesquels coulisse un piston solidaire d'une tige d'actionnement 80, 90, chaque tige étant ramenée en position haute par un ressort 81, 91.In accordance with Figures 3 and 4 these two manual pumps 8, 9 are carried by the same body 10 disposed in the chamber of the tank 5, this body 10 having two cylinders in parallel in which slides a piston secured to an actuating rod 80, 90, each rod being brought upwards by a spring 81, 91.

Ces deux pompes 8, 9 comportent respectivement un conduit d'entrée 82, 92 dont l'extrémité est munie classiquement d'un clapet à bille permettant l'introduction de l'eau dans le corps 10 lors de la montée du piston et interdisant le passage de l'eau à travers le conduit d'entrée 82, 92 lors de la descente du piston.These two pumps 8, 9 respectively comprise an inlet duct 82, 92 whose end is conventionally equipped with a ball valve allowing the introduction of water into the body 10 during the rise of the piston and prohibiting the passage of the water through the inlet duct 82, 92 during the descent of the piston.

Le conduit d'entrée 92 de la seconde pompe 9 est avantageusement relié à un tube, non représenté sur les figures, débouchant à l'arrière du réservoir 5 de sorte que la pompe 9 reste alimentée en eau lorsque le fer est disposé verticalement, par exemple pour défroisser les rideaux.The inlet duct 92 of the second pump 9 is advantageously connected to a tube, not shown in the figures, opening at the rear of the tank 5 so that the pump 9 remains supplied with water when the iron is arranged vertically, for example. example to smooth the curtains.

Conformément aux figures 3 à 6, la première pompe 8 comporte un conduit de sortie 83 débouchant latéralement au corps 10 et la seconde pompe 9 comporte un orifice de sortie 9B muni d'un manchon de connexion 93 débouchant verticalement à la base du corps 10.In accordance with Figures 3 to 6 , the first pump 8 comprises an outlet conduit 83 opening laterally to the body 10 and the second pump 9 has an outlet orifice 9B provided with a connection sleeve 93 opening vertically to the base of the body 10.

Le manchon de connexion 93 reçoit un joint d'étanchéité 94, avantageusement réalisé en silicone ou en matériau néoprène, assurant une liaison étanche avec un tube d'alimentation 95 débouchant au dessus de la seconde chambre de vaporisation 11, au niveau d'un second joint étanchéité 96, visible sur les figures 1 et 2.The connecting sleeve 93 receives a seal 94, advantageously made of silicone or neoprene material, providing a tight connection with a feed tube 95 opening above the second vaporization chamber 11, at a second level. seal 96, visible on the figures 1 and 2 .

Afin d'éviter que la vapeur produite dans la seconde chambre de vaporisation 11 ne remonte dans la seconde pompe 9, l'orifice de sortie 9B est muni d'un clapet à bille comprenant une bille 97 ramenée contre l'orifice de sortie 9B par un ressort 98 s'étendant entre la bille 97 et le joint d'étanchéité 94.In order to prevent the vapor produced in the second vaporization chamber 11 goes up in the second pump 9, the outlet 9B is provided with a ball valve comprising a ball 97 brought against the outlet orifice 9B by a spring 98 extending between the ball 97 and the seal sealing 94.

Plus particulièrement selon l'invention, le circuit d'alimentation de la seconde chambre de vaporisation 11 comporte un dispositif de sécurité protégeant le réservoir contre les suppressions qui pourraient subvenir si la température s'élevait de manière importante dans le réservoir 5 alors que le boisseau goutte-à-goutte était fermé ainsi que la trappe 7 du réservoir.More particularly according to the invention, the supply circuit of the second vaporization chamber 11 comprises a safety device protecting the reservoir against the deletions that could occur if the temperature rose significantly in the tank 5 while the bushel drip was closed as well as the hatch 7 of the tank.

Ce dispositif de sécurité est constitué par une ouverture 12 obturée par un clapet capable de libérer un passage au travers de ladite ouverture 12 lorsque la pression régnant à l'intérieur du réservoir 5 atteint une valeur prédéterminée.This safety device is constituted by an opening 12 closed by a valve capable of releasing a passage through said opening 12 when the pressure inside the reservoir 5 reaches a predetermined value.

Conformément aux figures 5 et 6, l'ouverture 12 est portée par le manchon de connexion 93 de la seconde pompe 9 et le clapet est avantageusement constitué par une paroi 94A faisant partie intégrante du joint s'étanchéité 94. La paroi 94A s'étend à l'extrémité supérieure du joint d'étanchéité 94, pour venir devant l'ouverture 12, et à l'intérieur du manchon de connexion 93 en épousant la forme cylindrique de l'alésage intérieur de ce dernier.In accordance with Figures 5 and 6 , the opening 12 is carried by the connecting sleeve 93 of the second pump 9 and the valve is advantageously constituted by a wall 94A forming an integral part of the seal seal 94. The wall 94A extends to the upper end of the seal 94, to come in front of the opening 12, and inside the connecting sleeve 93 by marrying the cylindrical shape of the inner bore of the latter.

A titre d'exemple, l'ouverture 12 du manchon de connexion 93 présente la forme d'un carré de 2 mm de côté et la paroi 94A présente la forme d'une languette d'une épaisseur de l'ordre de 0.4 mm, d'une hauteur de l'ordre de 3 mm et d'une largeur de l'ordre de 3 mm se réduisant progressivement de la base de la languette vers son extrémité libre.For example, the opening 12 of the connection sleeve 93 has the shape of a square of 2 mm side and the wall 94A has the shape of a tongue with a thickness of the order of 0.4 mm, a height of about 3 mm and a width of about 3 mm gradually decreasing from the base of the tongue to its free end.

Une telle paroi présente l'intérêt d'assurer une fermeture étanche de l'ouverture 12 lors de l'utilisation de la seconde pompe 9 pour la production de vapeur, la pression de vapeur générée dans la seconde chambre de vaporisation 11 ayant tendance à maintenir la paroi 94A appliquée contre les bords de l'ouverture 12 assurant ainsi une parfaite étanchéité à la vapeur, comme cela est illustré sur la figure 5.Such a wall has the advantage of ensuring a tight closure of the opening 12 when using the second pump 9 for the production of steam, the vapor pressure generated in the second vaporization chamber 11 tending to maintain the wall 94A applied against the edges of the opening 12 thus ensuring perfect vapor tightness, as illustrated in FIG. figure 5 .

A l'inverse, lorsque le fer est utilisé comme un fer sec avec le boisseau goutte-à-goutte fermé et que l'échauffement du réservoir 5 provoque une élévation de la pression d'une valeur prédéterminée, par exemple de l'ordre de 5 à 30 mbar, alors la pression appliquée sur la paroi 94A est telle que cette dernière se déforme vers l'intérieur du manchon de connexion 93 laissant ainsi s'échapper l'air et les éventuelles gouttelettes d'eau en direction de la seconde chambre de vaporisation 11, ainsi que cela est illustré par les flèches sur la figure 6.Conversely, when the iron is used as a dry iron with the drip plug closed and the heating of the tank 5 causes a rise in pressure by a predetermined value, for example of the order of 5 to 30 mbar, then the pressure applied on the wall 94A is such that the latter is deformed towards the inside of the connecting sleeve 93 thus allowing the air and the possible droplets of water to escape towards the second vaporization chamber 11, as well as that this is illustrated by the arrows on the figure 6 .

Les éventuelles gouttelettes d'eau transportées par la vapeur sont alors totalement vaporisées dans la chambre de vaporisation 11, et la vapeur s'échappe progressivement par les trous de sortie 2A de la semelle, sans surprendre l'utilisateur.Any water droplets carried by the steam are then completely vaporized in the vaporization chamber 11, and the steam escapes gradually through the outlet holes 2A of the sole, without surprising the user.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Ainsi, dans une variante de réalisation l'ouverture pourra être réalisée sur le conduit reliant le manchon de connexion de la pompe à la seconde chambre de vaporisation.Thus, in an alternative embodiment, the opening may be made on the conduit connecting the connection sleeve of the pump to the second vaporization chamber.
