Description

La présente invention se rapporte à un appareil électroménager de repassage comportant une cuve pour la génération de vapeur sous pression et se rapporte plus particulièrement à un appareil dans lequel la cuve comprend un fond surmonté d'une paroi latérale comprenant un orifice de vidange permettant le rinçage de la cuve et l'évacuation du tartre.The present invention relates to a domestic ironing appliance comprising a tank for the generation of steam under pressure and relates more particularly to an apparatus in which the tank comprises a bottom surmounted by a side wall comprising a drain orifice for rinsing of the tank and the evacuation of tartar.

Il est connu, de la demande de brevet FR2835041 déposée par la demanderesse, un générateur de vapeur comportant une cuve pour la production de vapeur sous pression comprenant un fond surmonté d'une paroi latérale munie d'un orifice de vidange permettant le rinçage de la cuve et l'évacuation du tartre.It is known from the patent application FR2835041 filed by the applicant, a steam generator comprising a vessel for the production of pressurized steam comprising a bottom surmounted by a side wall provided with a drain hole for rinsing the tank and the evacuation of scale.

Dans cet appareil, l'orifice de vidange est réalisé, pour des questions de fabrication, au-dessus d'un bord arrondi réalisant la jonction entre le fond et la paroi latérale de sorte qu'il se trouve légèrement surélevé par rapport au fond de la cuve. Ainsi, il résulte un volume important ne s'écoulant pas naturellement par l'orifice de vidange lorsque la cuve repose à plat et il n'est pas possible d'effectuer une vidange intégrale de l'eau contenue dans la cuve sans incliner fortement la cuve ou secouer cette dernière.In this apparatus, the discharge orifice is made, for manufacturing purposes, above a rounded edge forming the junction between the bottom and the side wall so that it is slightly raised relative to the bottom of the tank. Thus, a large volume does not flow naturally through the drain orifice when the tank rests flat and it is not possible to perform a complete emptying of the water contained in the tank without strongly tilting the tank or shake it.

Aussi, un but de la présente invention est de remédier à cet inconvénient en proposant un appareil électroménager de repassage comprenant une cuve pour la génération de vapeur sous pression qui soit simple et économique à réaliser et dans lequel le volume d'eau de la cuve qui ne s'écoule pas naturellement par l'orifice de vidange lorsque la cuve repose à plat est fortement réduit.Also, an object of the present invention is to overcome this disadvantage by providing an ironing appliance comprising a vessel for the generation of steam under pressure which is simple and economical to produce and in which the volume of water in the tank which does not flow naturally through the drain port when the tank is lying flat is greatly reduced.

A cet effet, l'invention a pour objet un appareil électroménager de repassage comportant une cuve pour la génération de vapeur sous pression, la cuve comportant un fond surmonté d'une paroi latérale comprenant un orifice de vidange fermé par un bouchon amovible, la cuve présentant un bord arrondi à la jonction entre le fond et la paroi latérale, caractérisé en ce que le fond présente à l'intérieur de la cuve, en bordure de la paroi latérale, un renfoncement au niveau duquel le bord arrondi de la cuve est abaissé et où la paroi latérale présente une partie s'étendant d'avantage vers le bas et en ce que l'orifice de vidange est ménagé au moins partiellement dans ladite partie abaissée de la paroi latérale.For this purpose, the subject of the invention is an ironing appliance with a vessel for the generation of steam under pressure, the vessel having a bottom surmounted by a side wall comprising a drain orifice closed by a removable cap, the tank having a rounded edge at the junction between the bottom and the side wall, characterized in that the bottom has inside the tank, at the edge of the side wall, a recess at which the rounded edge of the bowl is lowered and the side wall has a further downwardly extending portion and that the drain hole is provided at least partially in said lowered portion of the wall lateral.

Une telle caractéristique permet de créer sur la paroi latérale une extension vers le bas venant en regard du fond de la cuve où l'orifice de vidange peut être facilement disposé de manière abaissée.Such a feature allows to create on the side wall a downward extension coming opposite the bottom of the tank where the drain hole can be easily arranged in a lowered manner.

Selon une autre caractéristique de l'invention, en dehors du renfoncement, le fond de la cuve est sensiblement plat, la cuve étant fixée dans un boîtier de telle sorte que la partie plane du fond se trouve disposée sensiblement horizontalement lorsque le boîtier repose sur un plan de travail horizontal.According to another characteristic of the invention, outside the recess, the bottom of the tank is substantially flat, the tank being fixed in a housing so that the flat part of the bottom is arranged substantially horizontally when the housing rests on a horizontal work plan.

Selon une autre caractéristique de l'invention, la profondeur du renfoncement est supérieure ou égale au rayon de l'orifice de vidange.According to another characteristic of the invention, the depth of the recess is greater than or equal to the radius of the emptying orifice.

Une telle caractéristique permet d'abaisser l'orifice de vidange de telle sorte que le bord inférieur de ce dernier parvienne au niveau ou en dessous du niveau du fond de la cuve, pour favoriser la vidange de cette dernière.Such a characteristic makes it possible to lower the emptying orifice so that the lower edge of the latter reaches at or below the level of the bottom of the tank, to promote the emptying of the latter.

Selon une autre caractéristique de l'invention, l'orifice de vidange est disposé sur la paroi latérale de telle sorte que le bord inférieur de l'orifice de vidange se trouve dans le prolongement de la partie plane du fond de la cuve.According to another characteristic of the invention, the drain orifice is disposed on the side wall so that the lower edge of the drain hole is in the extension of the flat part of the bottom of the tank.

Une telle caractéristique permet de vider par gravité l'intégralité de l'eau contenue dans le fond de la cuve, en dehors du renfoncement.Such a characteristic makes it possible to empty by gravity all the water contained in the bottom of the tank, outside the recess.

Selon une autre caractéristique de l'invention, la partie plane du fond de la cuve est au contact thermique d'un corps chauffant.According to another characteristic of the invention, the flat part of the bottom of the tank is in thermal contact with a heating body.

Selon une autre caractéristique de l'invention, la cuve est mise en forme par emboutissage.According to another characteristic of the invention, the tank is shaped by stamping.

Une telle caractéristique permet la réalisation de la cuve de façon économique.Such a feature allows the realization of the tank economically.

Selon une autre caractéristique de l'invention, la cuve est réalisée dans un matériau métallique, de préférence en acier inoxydable.According to another characteristic of the invention, the tank is made of a metallic material, preferably stainless steel.

Selon une autre caractéristique de l'invention, l'orifice de vidange est défini par une ouverture de la cuve qui est réalisée par une opération d'emboutissage.According to another characteristic of the invention, the emptying orifice is defined by an opening of the tank which is made by a stamping operation.

Un tel mode de fabrication présente l'avantage d'être peu coûteux.Such a method of manufacture has the advantage of being inexpensive.

Selon encore une autre caractéristique de l'invention, la profondeur du renfoncement est supérieure ou égale au rayon de l'orifice de vidange.According to yet another characteristic of the invention, the depth of the recess is greater than or equal to the radius of the emptying orifice.

Une telle caractéristique permet d'obtenir un abaissement correspondant de la paroi latérale au niveau du renfoncement de sorte que l'orifice de vidange peut être disposé sur la paroi latérale avec le bord inférieur de l'orifice de vidange situé au niveau ou en dessous du fond de la cuve en bordure du renfoncement.Such a characteristic makes it possible to obtain a corresponding lowering of the side wall at the recess so that the drain orifice can be arranged on the side wall with the lower edge of the drain orifice located at or below the bottom of the tank at the edge of the recess.

Selon une autre caractéristique de l'invention, l'appareil comporte un fer à repasser relié par un cordon au boîtier générateur de vapeur et la cuve génère de la vapeur sous une pression supérieure à 4 bars.According to another characteristic of the invention, the apparatus comprises an iron connected by a cord to the steam generator housing and the vessel generates steam under a pressure greater than 4 bar.

Un tel appareil présente l'avantage d'assurer de très bonnes performances de repassage.Such a device has the advantage of ensuring very good ironing performance.

Selon une autre caractéristique de l'invention la cuve reçoit un récipient récupérateur de tartre qui est introduit par l'orifice de vidange, ledit récipient étant avantageusement solidaire du bouchon.According to another characteristic of the invention, the tank receives a tartar recovery vessel which is introduced through the drain orifice, said vessel being advantageously secured to the stopper.

Une telle caractéristique présente l'avantage d'une grande ergonomie d'utilisation en permettant de récupérer simplement la plus grande partie du tartre dans le récipient récupérateur, les particules de tartre les plus fines restant dans la cuve étant éliminées avec l'eau s'écoulant par l'orifice de tartre.Such a feature has the advantage of great ergonomics of use by simply recovering most of the scale in the recovery vessel, the tart particles finest remaining in the tank being removed with water s' flowing through the tartar orifice.

En particulier, un tel récipient récupérateur de tartre permet à l'utilisateur de visualiser rapidement l'état d'entartage de la cuve et d'adapter en conséquence la périodicité des opérations de vidange.In particular, such a tartar recovery container allows the user to quickly visualize the state of quarantine of the tank and adapt accordingly the periodicity of the emptying operations.

La paroi latérale 42 de la cuve comporte également une ouverture 44 réalisée par emboutissage disposée dans la partie basse de la cuve 42, cette ouverture recevant un tube 6 rigide monté par vissage puis collage dans l'ouverture 43.The side wall 42 of the tank also comprises an opening 44 made by stamping arranged in the lower part of the tank 42, this opening receiving a rigid tube 6 mounted by screwing and then gluing in the opening 43.

Comme on peut le voir sur les figures 4 et 5, le tube 6 comprend une première extrémité ouverte débouchant dans la cuve 4 définissant un orifice de vidange 60 et une seconde extrémité, débouchant sur un côté du boîtier 1, fermée par un bouchon 7 amovible.As can be seen on the Figures 4 and 5 , the tube 6 comprises a first open end opening into the tank 4 defining a drain port 60 and a second end, opening on one side of the housing 1, closed by a removable cap 7.

Le tube 6 comporte également une entrée latérale 61 reliée par un tuyau d'alimentation 62 à une pompe 8 électromagnétique fournissant une pression de l'ordre de 15 bars, la pompe 8 permettant de réapprovisionner régulièrement la cuve 4 avec de l'eau en provenance du réservoir 13 lors d'une séance de repassage.The tube 6 also comprises a lateral inlet 61 connected by a supply pipe 62 to an electromagnetic pump 8 providing a pressure of the order of 15 bars, the pump 8 making it possible to regularly refill the tank 4 with water coming from tank 13 during an ironing session.

Conformément aux figures 3 à 5, le fond 41 de la cuve 4 présente un renfoncement 45 s'étendant en bordure de la paroi latérale 42 et au niveau duquel le bord arrondi 43 de la cuve est incurvé vers le bas, la paroi latérale 42 présentant à cet endroit une partie 42A qui s'étend plus bas que le reste de la paroi latérale 42 sur le pourtour de la cuve 4.In accordance with Figures 3 to 5 , the bottom 41 of the tank 4 has a recess 45 extending at the edge of the side wall 42 and at which the rounded edge 43 of the tank is curved downwards, the side wall 42 having at this location a portion 42A which extends lower than the rest of the side wall 42 on the periphery of the tank 4.

Plus particulièrement selon l'invention, l'ouverture 44 recevant le tube 6 est ménagée dans la partie 42A de la paroi latérale 42 de manière à ce que l'orifice de vidange 60 se trouve le plus bas possible par rapport au fond 41 plat de la cuve 4.More particularly according to the invention, the opening 44 receiving the tube 6 is formed in the portion 42A of the side wall 42 so that the emptying orifice 60 is as low as possible relative to the bottom 41 flat of the tank 4.

De manière préférentielle, le renfoncement 45 présente une profondeur correspondant sensiblement au rayon de l'orifice de vidange 60 et l'ouverture 44 est disposée de telle sorte que le bord inférieur de l'orifice de vidange 60 se trouve dans le prolongement du fond 41 plat s'étendant en bordure du renfoncement 45.Preferably, the recess 45 has a depth substantially corresponding to the radius of the drain orifice 60 and the opening 44 is arranged such that the lower edge of the drain orifice 60 is in the extension of the bottom 41 flat extending along the recess 45.

La forme du renfoncement 45 est avantageusement optimisée pour que son volume soit réduit au maximum tout en permettant l'abaissement du bord inférieur de l'orifice de vidange 60 au niveau du fond 41 de la cuve 4, et est préférentiellement adaptée pour être facilement réalisable par emboutissage.The shape of the recess 45 is advantageously optimized so that its volume is reduced to the maximum while allowing the lower edge of the drain orifice 60 to be lowered at the bottom 41 of the tank 4, and is preferably adapted to be easily achievable. by stamping.

La paroi latérale 42, 42A au-dessus du renfoncement 45 présentant avantageusement une surface sensiblement plane facilitant la réalisation de l'ouverture 44 et notamment du filetage permettant le vissage de l'extrémité du tube 6.The side wall 42, 42A above the recess 45 advantageously having a substantially flat surface facilitating the realization of the opening 44 and in particular the threading for screwing the end of the tube 6.

A titre d'exemple, l'orifice de vidange 60 pourra présenter un diamètre de l'ordre de 13 mm et le renfoncement 45 présenter la forme d'une cuvette ayant une profondeur de l'ordre de 7 mm, ainsi qu'une largeur et une longueur de l'ordre 3 cm, pour une contenance inférieure à 6 cm3.By way of example, the drain orifice 60 may have a diameter of the order of 13 mm and the recess 45 may be in the form of a bowl having a depth of about 7 mm, as well as a width and a length of about 3 cm, for a capacity of less than 6 cm 3 .

L'appareil ainsi réalisé présente l'avantage de comporter une cuve 4 pour la génération de vapeur sous pression qui est simple et économique à réaliser et qui comporte un orifice de vidange 60 permettant une très bonne évacuation des particules de tartre sans que l'utilisateur n'ait besoin d'incliner ou de secouer le boîtier de l'appareil.The apparatus thus produced has the advantage of comprising a tank 4 for the generation of pressurized steam which is simple and economical to produce and which comprises a drain orifice 60 allowing a very good evacuation of scale particles without the user does not need to tilt or shake the housing of the unit.

En effet, lors de l'ouverture du bouchon 7, la majeure partie de l'eau contenue dans la cuve 4 s'écoule naturellement par l'orifice de vidange 60 lorsque le boîtier repose à plat sur un plan de travail, seule la très faible quantité d'eau contenue dans le renfoncement 45 restant piégée dans la cuve 4.Indeed, when opening the cap 7, most of the water contained in the tank 4 flows naturally through the drain port 60 when the housing rests flat on a work plane, only the very low amount of water contained in the recess 45 remaining trapped in the tank 4.

De plus, la présence du renfoncement 45 dans le fond de la cuve 4 permet de créer sur la paroi latérale 42 une partie 42A abaissée, présentant une surface sensiblement plane, venant en regard du fond 41 de la cuve où l'ouverture destinée à recevoir l'orifice de vidange 60 peut être facilement réalisée par emboutissage.In addition, the presence of the recess 45 in the bottom of the tank 4 allows to create on the side wall 42 a lowered portion 42A, having a substantially flat surface, facing the bottom 41 of the tank where the opening intended to receive the emptying orifice 60 can be easily made by stamping.

La figure 6, illustre un second mode de réalisation de l'invention dans lequel le bouchon 7 fermant l'orifice de vidange 60 est solidaire d'un récipient 9 récupérateur de tartre semblable à celui décrit plus en détails dans la demande de brevet FR 2904683 déposée par la demanderesse.The figure 6 , illustrates a second embodiment of the invention wherein the plug 7 closing the drain port 60 is integral with a container 9 similar to the calculator recovery tank described in more detail in the application for FR 2904683 filed by the plaintiff.

Un tel mode de réalisation présente l'avantage de pouvoir récupérer les particules de tartre les plus grosses par le biais du récipient 9 récupérateur de tartre, ce qui permet de visualiser l'état d'entartrage de la cuve et d'adapter en conséquence la périodicité des opérations de vidange. L'extraction du récipient 9 permet simultanément d'évacuer la plus grande partie de l'eau contenue dans la cuve par l'orifice de vidange et d'évacuer avec cette dernière les éventuelles particules de tartre, plus fines, contenues dans l'eau, seul un faible volume d'eau restant contenu dans la cuve au niveau du renfoncement.Such an embodiment has the advantage of being able to recover the largest scale particles by means of the vessel 9 scavenger recovery, which allows to visualize the scaling state of the tank and adapt accordingly the periodicity of the emptying operations. The extraction of the container 9 simultaneously evacuates most of the water contained in the tank through the drain orifice and evacuate with it any finer scale particles, contained in the water , only a small volume of water remaining contained in the tank at the recess.
