Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des appareils électroménagers comportant une cuve pour la génération de vapeur sous pression et un circuit d'alimentation configuré pour alimenter en eau la cuve à partir d'eau contenue dans un réservoir.The present invention relates to the field of household appliances comprising a tank for generating pressurized steam and a supply circuit configured to supply the tank with water from water contained in a tank.

Etat de la techniqueState of the art

Un appareil de repassage et/ou de défroissage comporte de façon connue un réservoir, une cuve pour la génération de vapeur sous pression, et un circuit d'alimentation configuré pour alimenter en eau la cuve à partir d'eau contenue dans le réservoir, le circuit d'alimentation comprenant une pompe et, en aval de la pompe, un circuit de dérivation configuré pour renvoyer une partie de l'eau issue de la pompe vers le réservoir.An ironing and / or smoothing appliance comprises, in a known manner, a tank, a tank for generating pressurized steam, and a supply circuit configured to supply the tank with water from water contained in the tank, the supply circuit comprising a pump and, downstream of the pump, a bypass circuit configured to return part of the water from the pump to the reservoir.

Un tel circuit de dérivation permet d'une part de faciliter l'amorçage de la pompe au démarrage de l'appareil de repassage et/ou de défroissage, soit à la première utilisation de l'appareil de repassage et/ou de défroissage soit lorsque le réservoir a été préalablement entièrement vidé, et d'autre part d'évacuer vers le réservoir des éventuelles bulles d'air présentes dans la pompe.Such a bypass circuit makes it possible, on the one hand, to facilitate the priming of the pump when the ironing and / or anti-crease appliance starts up, or when the ironing and / or anti-crease appliance is used for the first time, or when the reservoir has been completely emptied beforehand, and on the other hand to evacuate any air bubbles present in the pump to the reservoir.

Un inconvénient d'un tel circuit de dérivation réside dans le fait que, lors de l'arrêt de l'appareil de repassage et/ou de défroissage, la pression dans la cuve diminue (du fait du refroidissement de la cuve), et provoque un effet d'aspiration dans le circuit de dérivation de sorte que l'eau contenue dans le circuit dérivation est aspirée dans la cuve.A drawback of such a bypass circuit lies in the fact that, when the ironing and / or anti-crease appliance is stopped, the pressure in the tank decreases (due to the cooling of the tank), and causes a suction effect in the bypass circuit so that the water contained in the bypass circuit is sucked into the tank.

Or, il est important de minimiser la quantité d'eau aspirée dans la cuve pour éviter que cette dernière ne contienne une quantité d'eau trop importante au prochain démarrage de l'appareil de repassage et/ou de défroissage, ce qui allongerait le temps de chauffe de la cuve.However, it is important to minimize the amount of water sucked into the tank to prevent the latter from containing too much water the next time the ironing and / or steamer is started up, which would lengthen the time. for heating the tank.

De plus, un sur-remplissage intempestif de la cuve peut perturber l'estimation de la quantité d'eau contenue dans la cuve, et donc nuire au fonctionnement de l'appareil de repassage et/ou de défroissage.In addition, untimely overfilling of the tank can disturb the estimation of the quantity of water contained in the tank, and therefore harm the operation of the ironing and / or anti-crease appliance.

Afin de limiter la quantité d'eau qui est aspirée dans la cuve lors de l'arrêt d'un l'appareil de repassage et/ou de défroissage, il est connu d'équiper le circuit de dérivation d'une cheminée de refoulement qui s'étend à l'intérieur du réservoir et qui débouche au-dessus d'un niveau de remplissage maximal du réservoir.In order to limit the quantity of water which is sucked into the tank when stopping an ironing and / or anti-crease appliance, it is known practice to equip the bypass circuit with a discharge chimney which extends inside the tank and opens above a maximum fill level of the tank.

Une telle configuration de la cheminée de refoulement permet, du fait que cette dernière débouche au-dessus du niveau de remplissage maximal du réservoir, d'éviter que l'eau contenue dans le réservoir soit aspirée dans le circuit de dérivation et dans la cuve, et donc de limiter la quantité d'eau qui est aspirée dans la cuve.Such a configuration of the delivery chimney makes it possible, because the latter opens above the maximum filling level of the tank, to prevent the water contained in the tank from being sucked into the bypass circuit and into the tank, and therefore to limit the quantity of water which is sucked into the tank.

Toutefois, pour minimiser la quantité d'eau pouvant être aspirée dans la cuve, il est également important de minimiser la quantité d'eau contenue dans le circuit de dérivation. Ainsi, il est important d'avoir un circuit de dérivation de faible volume et donc d'avoir une cheminée de refoulement présentant une faible section de passage.However, to minimize the amount of water that can be drawn into the tank, it is also important to minimize the amount of water contained in the bypass circuit. Thus, it is important to have a small volume bypass circuit and therefore to have a discharge chimney with a small flow section.

Une cheminée de refoulement présentant une faible section de passage peut être obtenue en fabriquant le réservoir et la cheminée de refoulement par un procédé de moulage qui fait appel à un moule relativement complexe, et qui comprend notamment une étape de surmoulage durant laquelle deux parties de réservoir, qui définissent chacune partiellement la cheminée de refoulement, sont surmoulées.A discharge chimney having a small passage section can be obtained by manufacturing the reservoir and the discharge chimney by a molding process which uses a relatively complex mold, and which includes in particular an overmolding step during which two parts of the tank , which each partially define the delivery chimney, are overmolded.

Toutefois, les coûts de fabrication d'un appareil dont le réservoir et la cheminée de refoulement sont fabriqués par un tel procédé de surmoulage s'avèrent relativement élevés. Ainsi, un tel procédé de fabrication est inapproprié pour certaines gammes d'appareils.However, the manufacturing costs of an apparatus of which the reservoir and the delivery chimney are manufactured by such an overmolding process turn out to be relatively high. Thus, such a manufacturing process is inappropriate for certain ranges of devices.

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à tout ou partie de ces inconvénients.The present invention aims to remedy all or part of these drawbacks.

L'unité de base 3 comporte plus particulièrement un boîtier 7 qui est réalisé par exemple par l'assemblage de pièces en matière plastique, et un réservoir 8 qui est monté de manière amovible sur le boîtier 7. Le réservoir 8 peut par exemple être réalisé en matériau plastique, et être logé au moins partiellement dans un emplacement de réception 9 prévu sur le boîtier 7.The base unit 3 more particularly comprises a housing 7 which is made for example by assembling plastic parts, and a reservoir 8 which is removably mounted on the housing 7. The reservoir 8 can for example be made made of plastic material, and be housed at least partially in a receiving location 9 provided on the housing 7.

Le réservoir 8 comporte plus particulièrement un orifice de remplissage 10 par l'intermédiaire duquel le réservoir 8 peut être rempli d'eau jusqu'à un niveau de remplissage maximal 11.The reservoir 8 more particularly comprises a filling orifice 10 through which the reservoir 8 can be filled with water up to a maximum filling level 11.

Comme montré sur la figure 5, le réservoir comporte un corps de réservoir 8.1 et un couvercle de réservoir 8.2 qui est fixé au corps de réservoir 8.1, le couvercle de réservoir 8.2 comprenant l'orifice de remplissage 10 et un volet de fermeture 8.3 monté pivotant sur le couvercle de réservoir 8.2. Le volet de fermeture 8.3 peut pivoter d'une position ouverte, illustrée sur la figure 5, dans laquelle l'orifice de remplissage 10 est librement accessible à une position fermée, illustrée sur la figure 2, dans laquelle l'orifice de remplissage est masqué par le volet de fermeture 8.3.As shown on the figure 5 , the reservoir comprises a reservoir body 8.1 and a reservoir cover 8.2 which is fixed to the reservoir body 8.1, the reservoir cover 8.2 comprising the filling orifice 10 and a closing flap 8.3 pivotably mounted on the reservoir cover 8.2 .

L'unité de base 3 comporte également un générateur de vapeur qui est disposé dans le boîtier 7. Le générateur de vapeur comprend plus particulièrement une cuve 12 pour la génération de vapeur sous pression, et des moyens de chauffage (non visibles sur les figures) qui sont régulés pour chauffer la cuve 12 de manière à produire de la vapeur sous une pression supérieure à 4 bars, et par exemple de l'ordre de 5 à 6 bars.The base unit 3 also comprises a steam generator which is arranged in the housing 7. The steam generator more particularly comprises a vessel 12 for the generation of pressurized steam, and heating means (not visible in the figures). which are regulated to heat the tank 12 so as to produce steam under a pressure greater than 4 bars, and for example of the order of 5 to 6 bars.

L'unité de base 3 comporte en outre un circuit d'alimentation 13 configuré pour alimenter en eau la cuve 12 à partir d'eau contenue dans le réservoir 8. Le circuit d'alimentation 13 comprend notamment une pompe 14 qui est pourvue d'un orifice d'entrée 15, et un conduit d'admission 16 qui relie fluidiquement l'orifice d'entrée 15 de la pompe à un orifice d'aspiration 17 qui est prévu sur le réservoir 8 et qui débouche dans une partie inférieure du réservoir 8.The base unit 3 further comprises a supply circuit 13 configured to supply water to the tank 12 from water contained in the tank 8. The supply circuit 13 comprises in particular a pump 14 which is provided with an inlet port 15, and an inlet duct 16 which fluidly connects the inlet port 15 of the pump to a suction port 17 which is provided on the reservoir 8 and which opens into a lower part of the reservoir 8.

Le circuit d'alimentation 13 comprend en outre un conduit d'alimentation en eau 18 qui relie fluidiquement un orifice de sortie 19 de la pompe 14 à la cuve 12, et qui est donc configuré pour alimenter en eau la cuve 12.The supply circuit 13 further comprises a water supply duct 18 which fluidly connects an outlet port 19 of the pump 14 to the tank 12, and which is therefore configured to supply water to the tank 12.

La cuve 12 comprend un orifice de sortie de vapeur 21 qui est relié à l'outil de repassage et/ou de défroissage 4 par un conduit de vapeur intégré dans le cordon 5. De façon avantageuse, l'orifice de sortie de vapeur 21 est équipé d'une électrovanne, et l'outil de repassage et/ou de défroissage 4 comporte un bouton de commande 22 configuré pour commander l'ouverture de l'électrovanne lorsque le bouton de commande 22 est actionné par un utilisateur. Le bouton de commande 22 peut par exemple être disposé sous une poignée de l'outil de repassage et/ou de défroissage 4.The tank 12 includes a steam outlet 21 which is connected to the ironing and / or anti-crease tool 4 by a steam duct integrated into the bead 5. Advantageously, the steam outlet 21 is equipped with a solenoid valve, and the ironing and / or anti-crease tool 4 comprises a control button 22 configured to control the opening of the solenoid valve when the control button 22 is actuated by a user. The control button 22 can for example be placed under a handle of the ironing and / or anti-crease tool 4.

Le circuit d'alimentation 13 comprend également, en aval de la pompe 14, un circuit de dérivation 24 qui est configuré pour renvoyer en permanence une partie de l'eau issue de la pompe 14 vers le réservoir 8. Un tel circuit de dérivation 24 permet notamment de faciliter l'amorçage de la pompe 14 au démarrage de l'appareil de repassage et/ou de défroissage 2, soit à la première utilisation de l'appareil de repassage et/ou de défroissage 2 soit lorsque le réservoir 8 a été préalablement entièrement vidé.The supply circuit 13 also comprises, downstream of the pump 14, a bypass circuit 24 which is configured to permanently return a part of the water coming from the pump 14 to the reservoir 8. Such a bypass circuit 24 makes it possible in particular to facilitate the priming of the pump 14 when the ironing and / or anti-crease appliance 2 is started up, either when the ironing and / or anti-crease appliance 2 is used for the first time or when the tank 8 has been previously completely emptied.

Le circuit de dérivation 24 comprend un conduit de dérivation 25 qui est relié fluidiquement à l'orifice de sortie 19 de la pompe 14 et qui s'étend à l'extérieur du réservoir 8. Le circuit de dérivation 24 comprend en outre une cheminée de refoulement 26 qui s'étend à l'intérieur du réservoir 8 et qui débouche au-dessus du niveau de remplissage maximal 11 du réservoir 8. La cheminée de refoulement 26 est avantageusement formée par le corps de réservoir 8.1 et le couvercle de réservoir 8.2, et comporte une ouverture supérieure 8.4 qui est prévue sur le couvercle de réservoir 8.2 et qui débouche dans le réservoir 8 au-dessus du niveau de remplissage maximal 11 du réservoir 8.The bypass circuit 24 comprises a bypass duct 25 which is fluidly connected to the outlet port 19 of the pump 14 and which extends outside the reservoir 8. The bypass circuit 24 further comprises a chimney. delivery 26 which extends inside the reservoir 8 and which opens out above the maximum filling level 11 of the reservoir 8. The delivery duct 26 is advantageously formed by the reservoir body 8.1 and the reservoir cover 8.2, and has an upper opening 8.4 which is provided on the tank cover 8.2 and which opens into the tank 8 above the maximum filling level 11 of the tank 8.

Le conduit de dérivation 25 est plus particulièrement configuré pour relier fluidiquement l'orifice de sortie 19 de la pompe 14 à la cheminée de refoulement 26.The bypass duct 25 is more particularly configured to fluidly connect the outlet port 19 of the pump 14 to the delivery duct 26.

Comme montré sur la figure 6, la cheminée de refoulement 26 s'étend sensiblement verticalement lorsque l'appareil de repassage et/ou de défroissage 2 est disposé sur un support horizontal.As shown on the figure 6 , the delivery chimney 26 extends substantially vertically when the ironing and / or anti-crease appliance 2 is placed on a horizontal support.

Selon le mode de réalisation représenté sur les figures, le réservoir 8 et la cheminée de refoulement 26 forment une pièce monobloc, c'est-à-dire sont réalisés en une seule pièce. De façon avantageuse, la cheminée de refoulement 26 est obtenue directement avec le réservoir 8 par un procédé de moulage.According to the embodiment shown in the figures, the reservoir 8 and the delivery duct 26 form a single piece, that is to say are made in one piece. Advantageously, the delivery duct 26 is obtained directly with the reservoir 8 by a molding process.

Le circuit de dérivation 24 comporte de plus un insert 27 qui est rapporté à l'intérieur de la cheminée de refoulement 26 et qui comble une partie du volume interne de la cheminée de refoulement 26. L'insert 27 peut être réalisé en matériau plastique, par exemple en polystyrène expansé, et être obtenu par un procédé de moulage. De façon avantageuse, l'insert 27 est allongé et s'étend selon une direction d'extension qui est sensiblement parallèle à l'axe d'extension de la cheminée de refoulement 26. Selon le mode de réalisation représenté sur les figures, l'insert 27 est creux, c'est-à-dire qu'il renferme une cavité fermée étanche qui ne communique pas avec le réservoir 8.The bypass circuit 24 further comprises an insert 27 which is attached to the interior of the delivery chimney 26 and which fills part of the internal volume of the delivery chimney 26. The insert 27 can be made of plastic material, for example made of expanded polystyrene, and be obtained by a molding process. Advantageously, the insert 27 is elongated and extends in an extension direction which is substantially parallel to the extension axis of the delivery duct 26. According to the embodiment shown in the figures, the insert 27 is hollow, that is to say it contains a sealed closed cavity which does not communicate with the reservoir 8.

Comme montré plus particulièrement sur les figures 5 à 7, l'insert 27 présente une forme sensiblement complémentaire à celle de la cheminée de refoulement 26, et comporte une rainure périphérique 28. De manière avantageuse, la section transversale de l'insert 27 augmente progressivement en partant d'une première face d'extrémité 27.1 de l'insert 27 vers une deuxième face d'extrémité 27.2 de l'insert 27, qui est opposée à la première face d'extrémité 27.1, de sorte que l'insert 27 présente une forme convergente facilement démoulable.As shown more particularly on figures 5 to 7 , the insert 27 has a shape substantially complementary to that of the delivery duct 26, and comprises a peripheral groove 28. Advantageously, the cross section of the insert 27 gradually increases starting from a first end face 27.1 of the insert 27 towards a second end face 27.2 of the insert 27, which is opposite the first end face 27.1, so that the insert 27 has a converging shape that is easily demolded.

Selon le mode de réalisation représenté sur les figures, la rainure périphérique 28 est rectiligne et s'étend sur toute la hauteur de l'insert 27. La rainure périphérique 28 comporte plus particulièrement une première extrémité débouchant sur la première face d'extrémité 27.1 de l'insert 27 et une deuxième extrémité débouchant sur la deuxième face d'extrémité 27.2 de l'insert 27.According to the embodiment shown in the figures, the peripheral groove 28 is rectilinear and extends over the entire height of the insert 27. The peripheral groove 28 more particularly comprises a first end opening onto the first end face 27.1 of the insert 27 and a second end opening onto the second end face 27.2 of the insert 27.

La rainure périphérique 28 et la cheminée de refoulement 26 forment un canal de passage 29 qui relie fluidiquement l'intérieur du réservoir 8 à une partie du circuit de dérivation 24 qui est située en amont de la cheminée de refoulement 26, et plus particulièrement au conduit de dérivation 25. Le canal de passage 29 présente avantageusement une section transversale qui est sensiblement inférieure à la section transversale de la cheminée de refoulement 26.The peripheral groove 28 and the delivery duct 26 form a passage channel 29 which fluidly connects the interior of the reservoir 8 to a part of the bypass circuit 24 which is located upstream of the delivery duct 26, and more particularly to the duct branch 25. The passage channel 29 advantageously has a cross section which is substantially smaller than the cross section of the delivery duct 26.

Lors de l'arrêt de l'appareil de repassage et/ou de défroissage 2, la pression dans la cuve 12 diminue (du fait du refroidissement de la cuve 12), et provoque un effet d'aspiration dans le circuit de dérivation 24 de sorte que l'eau contenue dans le circuit d'aspiration 24 est aspirée dans la cuve 12. Or, du fait de la section réduite du canal de passage 29 et du fait que la cheminée de refoulement 26 débouche au-dessus du niveau de remplissage maximal 11 du réservoir 8, la quantité d'eau aspirée dans la cuve 12 est relativement faible et ne nuit donc pas au fonctionnement de l'appareil de repassage et/ou de défroissage 2.When stopping the ironing and / or anti-crease appliance 2, the pressure in the tank 12 decreases (due to the cooling of the tank 12), and causes a suction effect in the bypass circuit 24 of so that the water contained in the suction circuit 24 is sucked into the tank 12. However, due to the reduced section of the passage channel 29 and the fact that the delivery duct 26 opens above the filling level maximum 11 of the tank 8, the quantity of water sucked into the tank 12 is relatively small and therefore does not interfere with the operation of the ironing and / or anti-crease 2 appliance.

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.

Ainsi, dans une variante de réalisation non représentée, l'insert pourra être constitué par une pièce pleine.Thus, in an alternative embodiment not shown, the insert may be constituted by a solid part.

Ainsi, dans une autre variante de réalisation non représentée, la cheminée de refoulement pourra recevoir plusieurs inserts afin de former un canal de passage de section réduite.Thus, in another variant embodiment not shown, the delivery duct can receive several inserts in order to form a passage channel of reduced section.
