En effet, une telle évacuation des condensats évite que le flux de vapeur circulant dans la chambre interne ne se charge en gouttelettes d'eau et que ces gouttelettes d'eau soient expulsées par l'au moins un trou de sortie de vapeur.Such a configuration of the steaming head, and more particularly the presence of a condensate discharge orifice in the internal chamber, makes it possible to evacuate, outside the internal chamber, the condensates that would have formed in the internal chamber, and therefore to limit the risk of projection and / or capturing by capillary drops of water through the at least one steam outlet hole. Indeed, such a condensate evacuation prevents the flow of steam flowing in the inner chamber does load into water droplets and that these water droplets are expelled through the at least one steam outlet hole.
En outre, le fait que le circuit de retour de condensat débouche dans le conduit de vapeur ou dans le canal d'admission, permet par un dispositif simple et économique à mettre en oeuvre, de rediriger les condensats, évacués hors de la chambre interne, dans le conduit de vapeur de sorte que les condensats glissent par gravité le long du conduit de vapeur, et retombent dans le générateur de vapeur de l'unité de base où ils seront ensuite re-vaporisés. En particulier, grâce à cette solution, le conduit de vapeur est utilisé pour ramener les condensats vers le générateur de vapeur et il n'est pas nécessaire de faire appel à un circuit de retour de condensats spécifique, et dédié à cette seule fonction, coûteux à mettre en oeuvre.In addition, the fact that the condensate return circuit opens into the steam duct or into the inlet duct, allows by a simple and economical device to implement, to redirect the condensate, discharged from the internal chamber, in the steam duct so that the condensates slide by gravity along the steam duct, and fall back into the steam generator of the base unit where they will then be re-vaporized. In particular, thanks to this solution, the steam duct is used to return the condensate to the steam generator and it is not necessary to use a specific condensate return circuit, and dedicated to this single function, expensive to implement.
De plus, la configuration du circuit de retour de condensat permet d'éviter toute manipulation additionnelle d'un utilisateur pour vidanger la chambre interne ou un quelconque collecteur relié à la chambre interne et dont la tête de défroissage pourrait être pourvue.In addition, the configuration of the condensate return circuit makes it possible to avoid any additional manipulation of a user to empty the internal chamber or any manifold connected to the internal chamber and whose freezing head could be provided.
Ainsi, la tête de défroissage selon l'invention présente l'avantage d'être simple et économique à réaliser, tout en limitant grandement les risques de projection de gouttes d'eau sur un vêtement ou un linge à défroisser.Thus, the steaming head according to the invention has the advantage of being simple and economical to achieve, while greatly limiting the risk of splashing drops of water on a garment or cloth to unwind.
La tête de défroissage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The steaming head may further have one or more of the following features, taken alone or in combination.
Selon un mode de réalisation de l'invention, l'orifice de sortie débouche dans la chambre interne à un emplacement adapté pour que la trajectoire des gouttes d'eau entraînées par le flux de vapeur, et projetées dans la chambre interne au niveau de l'orifice de sortie, ne passe pas par l'au moins un trou de sortie de vapeur.According to one embodiment of the invention, the outlet orifice opens into the internal chamber at a location adapted to the trajectory of the drops of water entrained by the flow of steam, and projected into the internal chamber at the level of the outlet orifice, does not pass through the at least one steam outlet hole.

Selon un mode de réalisation de l'invention, le canal d'admission présente un coude à 90° en amont de l'orifice de sortie. La présence d'un tel coude induit une accélération du flux de vapeur s'écoulant dans le canal d'admission, et favorise donc la séparation des gouttes d'eau qui sont entraînées par le flux de vapeur, du flux de vapeur. Ces gouttes d'eau séparées sont plus particulièrement projetées sur une paroi extérieure du coude, et sont ensuite soufflées par le flux de vapeur le long de la paroi frontale et à l'opposé de l'orifice de sortie.According to one embodiment of the invention, the intake channel has a bend at 90 ° upstream of the outlet orifice. The presence of such a bend induces an acceleration of the flow of steam flowing in the intake channel, and thus promotes the separation of water drops that are entrained by the vapor flow, the vapor flow. These separate drops of water are more particularly projected on an outer wall of the elbow, and are then blown by the vapor flow along the front wall and away from the outlet orifice.

Selon un mode de réalisation de l'invention, l'orifice de sortie débouche dans la chambre interne tangentiellement à la paroi frontale de sorte que la vapeur sortant de l'orifice de sortie s'écoule le long de la paroi frontale.According to one embodiment of the invention, the outlet orifice opens into the internal chamber tangentially to the front wall so that the steam exiting the outlet orifice flows along the front wall.
Selon un mode de réalisation de l'invention, l'orifice de sortie débouche dans une partie supérieure de la chambre interne, et préférence au voisinage du sommet de la chambre interne.According to one embodiment of the invention, the outlet orifice opens into an upper part of the internal chamber, and preferably near the top of the inner chamber.
Selon un mode de réalisation de l'invention, l'orifice de sortie débouche dans la première chambre de diffusion, et par exemple au voisinage du sommet de la première chambre de diffusion.According to one embodiment of the invention, the outlet orifice opens into the first diffusion chamber, and for example in the vicinity of the top of the first diffusion chamber.
Selon un mode de réalisation de l'invention, la chambre interne comporte des canaux d'expulsion de vapeur s'étendant transversalement à la paroi frontale et communiquant avec l'au moins un trou de sortie de vapeur de sorte que la vapeur présente dans la chambre interne s'échappe à travers les canaux d'expulsion de vapeur et en direction de l'au moins un trou de sortie de vapeur. Une telle configuration des canaux d'expulsion de vapeur requiert une circulation de la vapeur dans la chambre interne avant que cette dernière ne puisse pénétrer dans les canaux d'expulsion de vapeur, ce qui favorise une séparation d'au moins une partie des gouttes d'eau entraînées par la vapeur, du flux de vapeur, et limite ainsi les risques de projections de gouttes d'eau par l'au moins un trou de sortie de vapeur.According to one embodiment of the invention, the internal chamber comprises vapor expulsion channels extending transversely to the front wall and communicating with the at least one steam outlet hole so that the steam present in the internal chamber escapes through the vapor expulsion channels and to the at least one steam outlet hole. Such a configuration of the vapor expulsion channels requires a circulation of the vapor in the internal chamber before the latter can penetrate the vapor expulsion channels, which promotes a separation of at least a portion of the drops of vapor. water entrained by the steam, vapor flow, and thus limits the risk of splashing drops of water through the at least one steam outlet hole.
Selon un mode de réalisation de l'invention, la première chambre de diffusion est traversée par les canaux d'expulsion de vapeur, les canaux d'expulsion de vapeur faisant saillie de la face interne de la paroi frontale et débouchant dans la deuxième chambre de diffusion. Une telle configuration des canaux d'expulsion de vapeur implique un écoulement de la vapeur entrant dans la chambre interne autour des canaux d'expulsion de vapeur et donc un réchauffement de ces derniers, avant que la vapeur ne s'échappe à l'extérieur de la tête de défroissage via les canaux d'expulsion de vapeur et l'au moins un trou de sortie de vapeur. Or, un tel réchauffement des canaux d'expulsion de vapeur limite grandement la condensation de gouttes d'eau sur les parois internes des canaux d'expulsion de vapeur, et ainsi la projection de gouttes d'eau à travers l'au moins un trou de sortie de vapeur.According to one embodiment of the invention, the first diffusion chamber is traversed by the steam expulsion channels, the steam expulsion channels protruding from the inner face of the front wall and opening into the second chamber of diffusion.

Selon un mode de réalisation de l'invention, chaque canal d'expulsion de vapeur a une section de passage qui est oblongue et qui présente une largeur diminuant à l'opposé de l'orifice de sortie.According to one embodiment of the invention, each steam expulsion channel has a passage section which is oblong and which has a decreasing width opposite the exit orifice.
Selon un mode de réalisation de l'invention, chaque canal d'expulsion de vapeur a une section de passage en forme de goutte d'eau pointant à l'opposé de l'orifice de sortie, et par exemple pointant vers le bas.According to one embodiment of the invention, each steam expulsion channel has a teardrop-shaped passage section pointing away from the exit orifice, and for example pointing downwards.
Selon un mode de réalisation de l'invention, chaque canal d'expulsion de vapeur comporte une nervure de barrage qui fait saillie à l'intérieur dudit canal d'expulsion de vapeur et qui forme un barrage s'opposant à l'écoulement de gouttelettes d'eau le long dudit canal d'expulsion de vapeur en direction de l'au moins un trou de sortie de vapeur. Ces dispositions participent encore à empêcher la projection de gouttelettes d'eau par l'au moins un trou de sortie de vapeur.According to one embodiment of the invention, each steam expulsion channel comprises a barrier rib which protrudes inside said vapor expulsion channel and which forms a barrier against the flow of droplets. of water along said steam expulsion channel to the at least one steam outlet hole. These arrangements still participate in preventing the projection of water droplets through the at least one steam outlet hole.

The condensate discharge orifice is for example arranged in a central portion of the bottom wall of the internal chamber.
Selon un mode de réalisation de l'invention, la paroi inférieure est courbée. Ces dispositions favorisent encore une séparation d'au moins une partie des gouttes d'eau entraînées par la vapeur s'écoulant dans la chambre interne, du flux de vapeur, et limitent encore les risques de projections de gouttes d'eau par l'au moins un trou de sortie de vapeur. En effet, les gouttelettes d'eau les plus grosses transportées par la vapeur restent collées contre la surface courbe sous l'effet de la force centrifuge.According to one embodiment of the invention, the bottom wall is curved. These arrangements further promote a separation of at least a portion of the water drops entrained by the steam flowing in the internal chamber, the flow of steam, and further limit the risk of splashing drops of water by the minus a steam outlet hole. Indeed, the largest water droplets transported by the steam remain glued against the curved surface under the effect of centrifugal force.
Selon un mode de réalisation de l'invention, le circuit de retour de condensat comporte une cavité de stockage de condensat ménagée dans la tête de défroissage, avantageusement sous la paroi inférieure de la chambre interne.According to one embodiment of the invention, the condensate return circuit comprises a condensate storage cavity formed in the steaming head, advantageously under the bottom wall of the internal chamber.
Selon un mode de réalisation de l'invention, la cavité de stockage de condensat est agencée de telle sorte que, lorsque la tête de défroissage est inclinée par rapport à l'horizontale, une paroi de la cavité de stockage de condensat empêche un écoulement des condensats contenus dans la cavité de stockage de condensat dans la chambre interne.According to one embodiment of the invention, the condensate storage cavity is arranged such that, when the steaming head is inclined relative to the horizontal, a wall of the condensate storage cavity prevents a flow of condensates contained in the condensate storage cavity in the inner chamber.
Selon un mode de réalisation de l'invention, les canaux d'expulsion de vapeur sont situés à distance de l'orifice d'évacuation de condensat, et avantageusement de la cavité de stockage de condensat.According to one embodiment of the invention, the vapor expulsion channels are located at a distance from the condensate discharge orifice, and advantageously from the condensate storage cavity.
Selon un mode de réalisation de l'invention, la première chambre de diffusion présente une section de passage diminuant progressivement selon la direction de circulation de la vapeur dans la première chambre de diffusion. Ces dispositions permettent d'accélérer la vapeur s'écoulant dans la première chambre de diffusion, et donc de favoriser le soufflage des condensats à l'opposé de l'orifice d'entrée, et en particulier vers l'orifice d'évacuation de condensat.According to one embodiment of the invention, the first diffusion chamber has a passage section gradually decreasing in the direction of circulation of the vapor in the first diffusion chamber. These arrangements make it possible to accelerate the steam flowing in the first diffusion chamber, and thus to promote the blowing of the condensates opposite the inlet orifice, and in particular towards the condensate outlet orifice. .
Selon un mode de réalisation de l'invention, l'orifice d'évacuation de condensat débouche dans la cavité de stockage de condensat.According to one embodiment of the invention, the condensate outlet opens into the condensate storage cavity.
Selon un mode de réalisation de l'invention, le circuit de retour de condensat comporte un canal de retour comprenant une première portion d'extrémité reliée fluidiquement à l'orifice d'évacuation de condensat, et une deuxième portion d'extrémité opposée à la première portion d'extrémité et faisant saillie dans le conduit de vapeur ou dans le canal d'admission, par exemple de plusieurs millimètres. Ces dispositions permettent notamment d'empêcher tout condensat qui s'écoulerait le long de la paroi interne du canal d'admission en direction de l'orifice d'entrée du canal d'admission ou le long de la paroi interne du conduit de vapeur en direction du générateur de vapeur, de pénétrer dans le canal de retour et de le remplir.According to one embodiment of the invention, the condensate return circuit comprises a return channel comprising a first end portion fluidly connected to the condensate discharge orifice, and a second end portion opposite to the first end portion and projecting into the steam duct or into the inlet channel, for example several millimeters.

Avantageusement, la deuxième portion d'extrémité du canal de retour est biseautée. Ces dispositions permettent de diriger le liquide s'écoulant dans le canal de retour vers la pointe de ce dernier et donc d'aider au désengorgement du canal de retour. De plus, cette forme biseautée du canal de retour permet de faciliter le passage du flux de vapeur, s'écoulant dans le canal d'admission, de part et d'autre de cet obstacle. Le fait que le canal de retour soit biseauté permet également d'éviter en partie que de la vapeur pénètre dans le canal de retour lors du premier passage de vapeur dans la tête de défroissage (lors d'un fonctionnement classique, la présence d'eau dans le canal de retour empêche la vapeur de remonter dans celui-ci).Advantageously, the second end portion of the return channel is tapered. These arrangements make it possible to direct the liquid flowing in the return channel towards the tip of the latter and thus to help the decongestion of the return channel. In addition, this beveled shape of the return channel facilitates the passage of the flow of steam, flowing in the intake channel, on either side of this obstacle. The fact that the return channel is beveled also makes it possible in part to prevent steam from entering the return channel during the first passage of steam in the steaming head (during a conventional operation, the presence of water in the return channel prevents the vapor from rising in it).
Selon un mode de réalisation de l'invention, le canal de retour est configuré pour être incliné par rapport à l'horizontale lorsque la paroi frontale s'étend sensiblement verticalement. Ces dispositions favorisent un écoulement des condensats contenus dans la cavité de stockage de condensat vers le conduit de vapeur ou le canal d'admission, et évident donc une accumulation de condensats dans la cavité de cavité de stockage de condensat.According to one embodiment of the invention, the return channel is configured to be inclined relative to the horizontal when the front wall extends substantially vertically. These arrangements promote a flow of condensates contained in the condensate storage cavity to the steam duct or intake duct, and thus evident a build-up of condensates in the condensate storage cavity cavity.
Selon un mode de réalisation de l'invention, le canal de retour présente une section de passage sensiblement constante.According to one embodiment of the invention, the return channel has a substantially constant passage section.
Selon un mode de réalisation de l'invention, la première portion d'extrémité du canal de retour débouche dans la cavité de stockage de condensat.According to one embodiment of the invention, the first end portion of the return channel opens into the condensate storage cavity.

Avantageusement, la chambre interne est délimitée par les parois internes de la cavité interne et la paroi frontale.According to one embodiment of the invention, the main body comprises an internal cavity and an access opening opening into the internal cavity, the front wall closing, preferably removably, the access opening. Advantageously, the internal chamber is delimited by the internal walls of the internal cavity and the front wall.

Lorsqu'un utilisateur souhaite défroisser un vêtement, il remplit le réservoir de liquide 4 de l'unité de base 3 avec par exemple de l'eau, puis appui sur un bouton de mise en marche de l'appareil de défroissage 2. Le générateur de vapeur 5 est alors alimenté électriquement de manière à générer de la vapeur qui s'échappe du générateur de vapeur 5 en direction de l'orifice d'entrée 18 du canal d'admission 17. La vapeur provenant du générateur de vapeur 5 s'écoule alors le long du canal d'admission 17, pénètre dans la chambre interne 21 via l'orifice de sortie 19 et est répartie sur une partie importante de la largeur de la face interne de la paroi frontale 10, du fait que le canal d'admission 17 présente une section de passage aplatie au niveau de l'orifice de sortie 19. Puis, la vapeur ayant pénétré dans la chambre interne 21 s'écoule en direction de la base de la chambre interne 21 et autour des canaux d'expulsion de vapeur 29, de manière à réchauffer ces derniers, avant d'être redirigée vers la deuxième chambre de diffusion 25 par la paroi inférieure 35 de la chambre interne 21. Enfin, la vapeur s'écoule à travers les canaux d'expulsion de vapeur 29 et est diffusée à l'extérieur de la tête de défroissage 6, au travers des trous de sortie de vapeur 13.When a user wishes to unwind a garment, he fills the
La présence du coude 22 en amont de l'orifice de sortie 19 induit une accélération du flux de vapeur s'écoulant dans le canal d'admission 17, et favorise donc la séparation des gouttes d'eau qui sont entraînées par le flux de vapeur, du flux de vapeur, tandis que la configuration de l'orifice de sortie 19 assure un soufflage, par le flux de vapeur, des gouttes d'eau séparées le long de la paroi frontale 10 et en direction de l'orifice d'évacuation de condensat 33, où ces dernières sont évacuées dans la cavité de stockage de condensat 36.The presence of the
En outre, la forme des canaux d'expulsion de vapeur 29 et le fait que ces derniers comportent des ouvertures inférieures 32 permettent aux condensats éventuellement formés dans les canaux d'expulsion de vapeur 29 (une telle formation étant limitée du fait du chauffage préalable des canaux d'expulsion de vapeur 29 par la vapeur s'écoulant dans la première chambre de diffusion 23) de tomber par gravité dans la chambre interne 21 et d'être évacués hors de cette dernière via l'orifice d'évacuation de condensat 33.In addition, the shape of the
Les condensats contenus dans la cavité de stockage de condensat 36 sont alors redirigés vers le conduit de vapeur 7, via le canal de retour 38, de sorte que les condensats glissent par gravité le long du conduit de vapeur 7, et retombent dans le générateur de vapeur 5 de l'unité de base 3 où ils seront ensuite re-vaporisés.The condensates contained in the
