Description

La présente invention se rapporte à une tête de défroissage d'un appareil de défroissage à la vapeur.The present invention relates to a steaming head of a steam steaming device.

Par exemple, US 2015/0252518 A1 divulgue une tête de défroissage d'un appareil de défroissage à la vapeur.For instance, US 2015/0252518 A1 discloses a steamer head of a steamer.

De façon connue, un appareil de défroissage à la vapeur comporte une unité de base destinée à produire un flux de vapeur, et une tête de défroissage reliée à l'unité de base par un conduit de vapeur dans lequel la vapeur produite par l'unité de base s'échappe librement vers la tête de défroissage, la tête de défroissage comportant une partie arrière formant une poignée de préhension et une partie avant comportant une paroi frontale comprenant une face de traitement destinée à venir en regard d'un vêtement à défroisser et munie de plusieurs trous de sortie de vapeur au travers desquels le flux de vapeur provenant de l'unité de base est diffusé.In known manner, a steam steamer comprises a base unit intended to produce a flow of steam, and a steamer head connected to the base unit by a steam conduit in which the steam produced by the unit base escapes freely towards the steaming head, the steaming head comprising a rear part forming a handle for gripping and a front part comprising a front wall comprising a treatment face intended to come opposite a garment to be steamed and provided with several steam outlet holes through which the flow of steam from the base unit is diffused.

Lors de l'utilisation d'une telle tête de défroissage, des gouttes d'eau entraînées par le flux de vapeur généré par l'unité de base, sont susceptibles d'être projetées ou captées par capillarité à travers l'au moins un trou de sortie de vapeur et donc de tâcher le vêtement ou le linge à défroisser.When using such a steamer head, drops of water entrained by the flow of steam generated by the base unit are likely to be projected or captured by capillarity through the at least one hole steam outlet and therefore stain the garment or linen to be smoothed.

La présente invention vise à remédier à cet inconvénient.The present invention aims to remedy this drawback.

Le problème technique à la base de l'invention consiste notamment à fournir une tête de défroissage qui soit de structure simple et économique, tout en permettant de limiter le risque de projection ou de captation par capillarité de gouttes d'eau sur un vêtement ou un linge à défroisser.The technical problem at the basis of the invention consists in particular in providing a steaming head which is of simple and economical structure, while making it possible to limit the risk of projection or capture by capillarity of drops of water on a garment or a steamer.

A cet effet, la présente invention concerne une tête de défroissage comportant un circuit de distribution de vapeur et une paroi frontale munie d'une face de traitement destinée à venir en regard d'un vêtement à défroisser, la face de traitement comprenant au moins un trou de sortie de vapeur, le circuit de distribution de vapeur comportant un canal d'admission comprenant un orifice d'entrée destiné à être connecté à un conduit de vapeur, caractérisée en ce que le circuit de distribution de vapeur comporte en outre une chambre interne et en ce que le canal d'admission comporte un orifice de sortie débouchant dans la chambre interne, la chambre interne comprenant un orifice d'évacuation de condensat communiquant avec un circuit de retour de condensat débouchant dans le conduit de vapeur ou dans le canal d'admission.To this end, the present invention relates to a steaming head comprising a steam distribution circuit and a front wall provided with a treatment face intended to come opposite a garment to be steamed, the treatment face comprising at least one steam outlet hole, the steam distribution circuit comprising an inlet channel comprising an inlet orifice intended to be connected to a steam conduit, characterized in that the steam distribution circuit further comprises an internal chamber and in that the inlet channel includes an outlet orifice opening into the internal chamber, the internal chamber comprising a condensate evacuation orifice communicating with a condensate return circuit opening into the steam conduit or into the inlet channel .

Une telle configuration de la tête de défroissage, et plus particulièrement la présence d'un orifice d'évacuation de condensat dans la chambre interne, permet d'évacuer, à l'extérieur de la chambre interne, les condensats qui se seraient formés dans la chambre interne, et donc de limiter les risques de projection et/ou de captation par capillarité de gouttes d'eau à travers l'au moins un trou de sortie de vapeur. 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 steamer head, and more particularly the presence of a condensate evacuation orifice in the internal chamber, makes it possible to evacuate, outside the internal chamber, the condensates which would have formed in the internal chamber, and therefore to limit the risks of projection and/or capture by capillarity of drops of water through the at least one steam outlet hole. Indeed, such an evacuation of the condensates prevents the flow of steam circulating in the internal chamber from becoming loaded with water droplets and these water droplets being 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 œuvre.In addition, the fact that the condensate return circuit opens into the steam duct or into the inlet channel, makes it possible, by means of a device that is simple and economical to implement, to redirect the condensates, evacuated out of the internal chamber, in the steam duct so that the condensates slide by gravity along the steam duct, and fall back into the base unit steam generator where they will then be re-vaporized. In particular, thanks to this solution, the steam duct is used to bring the condensates back to the steam generator and it is not necessary to use a specific condensate return circuit, and dedicated to this sole function, costly 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 by a user to drain the internal chamber or any collector connected to the internal chamber and with which the steamer 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 produce, while greatly limiting the risks of spraying drops of water on a garment or linen to be steamed.

La tête de défroissage peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The steaming head may also have one or more of the following characteristics, 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 suitable for 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, l'orifice d'évacuation de condensat est disposé à un endroit vers lequel l'eau présente dans la chambre interne s'écoule naturellement par gravité lorsque la tête de défroissage est orientée dans une position usuelle d'utilisation.According to one embodiment of the invention, the condensate discharge orifice is arranged at a location towards which the water present in the internal chamber flows naturally by gravity when the steamer head is oriented in a usual position. of use.

Selon un mode de réalisation de l'invention, la face de traitement est plane et comporte un contour de forme générale triangulaire.According to one embodiment of the invention, the treatment face is planar and comprises an outline of generally triangular shape.

Selon un mode de réalisation de l'invention, le canal d'admission présente une section de passage constante. Cette configuration du canal d'admission permet d'assurer une vitesse constante de la vapeur tout au long de son parcours dans le canal d'admission, lui évitant de refroidir par détente dans un espace plus vaste.According to one embodiment of the invention, the inlet channel has a constant passage section. This configuration of the intake channel makes it possible to ensure a constant speed of the vapor throughout its course in the intake channel, preventing it from cooling by expansion in a larger space.

Selon un mode de réalisation de l'invention, le canal d'admission présente une section de passage circulaire au niveau de l'orifice d'entrée et une section de passage aplatie au niveau de l'orifice de sortie.According to one embodiment of the invention, the inlet channel has a circular passage section at the level of the inlet orifice and a flattened passage section at the level of the outlet orifice.

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 inlet channel has a 90° bend upstream of the outlet orifice. The presence of such a bend induces an acceleration of the flow of steam flowing in the inlet channel, and therefore promotes the separation of the drops of water which are entrained by the flow of steam, from the flow of steam. These separate drops of water are more particularly projected onto an outer wall of the elbow, and are then blown by the flow of steam along the front wall and away from the outlet orifice.

Selon un mode de réalisation de l'invention, le coude présente un rayon de courbure interne compris entre 3,5 et 4,5 mm et un rayon de courbure externe compris entre 9 et 11 mm. Avantageusement, le coude présente un rayon de courbure interne de 4 mm et un rayon de courbure externe de 10 mm.According to one embodiment of the invention, the elbow has an internal radius of curvature comprised between 3.5 and 4.5 mm and an external radius of curvature comprised between 9 and 11 mm. Advantageously, the elbow has an internal radius of curvature of 4 mm and an external radius of curvature of 10 mm.

Selon un mode de réalisation de l'invention, la chambre interne comporte une première chambre de diffusion ménagée entre une face interne de la paroi frontale et une première face d'une paroi de séparation s'étendant à l'intérieur de la chambre interne, et une deuxième chambre de diffusion délimitée en partie par une deuxième face de la paroi de séparation opposée à la première face de la paroi de séparation, la deuxième chambre de diffusion étant en communication avec la première chambre de diffusion.According to one embodiment of the invention, the internal chamber comprises a first diffusion chamber formed between an internal face of the front wall and a first face of a separating wall extending inside the internal chamber, and a second diffusion chamber delimited in part by a second face of the dividing wall opposite the first face of the dividing wall, the second diffusion chamber being in communication with the first diffusion chamber.

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 vapor leaving 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 internal 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 near 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 steam 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 steam expulsion channels and towards the at least one steam outlet hole. Such a configuration of the steam expulsion channels requires circulation of the steam in the internal chamber before the latter can enter the steam expulsion channels, which promotes separation of at least part of the drops of water entrained by the steam, the flow of steam, and thus limits the risk of water droplets splashing 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 internal face of the front wall and opening into the second diffusion. Such a configuration of the steam expulsion channels implies a flow of the steam entering the internal chamber around the steam expulsion channels and therefore a heating of the latter, before the steam escapes outside of the steamer head via the steam expulsion channels and the at least one steam outlet hole. However, such heating of the steam expulsion channels greatly limits the condensation of water drops on the internal walls of the steam expulsion channels, and thus the projection of water drops through the at least one steam outlet hole .

Selon un mode de réalisation de l'invention, les canaux d'expulsion de vapeur s'étendent sensiblement perpendiculairement à la paroi frontale.According to one embodiment of the invention, the steam expulsion channels extend substantially perpendicular to the front wall.

Selon un mode de réalisation de l'invention, la surface externe de chaque canal d'expulsion de vapeur comporte des nervures, de préférence longitudinales, de sorte à augmenter la surface d'échange thermique entre la vapeur et ledit canal d'expulsion de vapeur. La surface externe de chaque canal d'expulsion de vapeur peut par exemple être crénelée.According to one embodiment of the invention, the outer surface of each steam expulsion channel comprises ribs, preferably longitudinal, so as to increase the heat exchange surface between the steam and said steam expulsion channel .

Selon un mode de réalisation de l'invention, la face de traitement comprend plusieurs trous de sortie de vapeur, et chaque canal d'expulsion de vapeur coïncide avec un trou de sortie de vapeur respectif.According to one embodiment of the invention, the treatment face comprises several steam outlet holes, and each steam expulsion channel coincides with a respective steam outlet hole.

Selon un mode de réalisation de l'invention, les canaux d'expulsion de vapeur présentent une section de passage cumulée correspondant sensiblement à la section de passage du canal d'admission.According to one embodiment of the invention, the steam expulsion channels have a combined passage section corresponding substantially to the passage section of the inlet channel.

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 width decreasing opposite the outlet 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 passage section in the shape of a drop of water pointing away from the outlet 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 vapor expulsion channel comprises a barrier rib which protrudes inside said vapor expulsion channel and which forms a barrier opposing the flow of droplets of water along said steam expulsion channel in the direction of the at least one steam outlet hole. These arrangements further contribute to preventing the projection of water droplets through the at least one steam outlet hole.

Avantageusement, la nervure de barrage de chaque canal d'expulsion de vapeur est disposée sensiblement au niveau d'une extrémité du canal d'expulsion de vapeur respectif tournée vers l'au moins un trou de sortie de vapeur.Advantageously, the barrier rib of each vapor expulsion channel is arranged substantially at the level of one end of the vapor expulsion channel. respective steam facing the at least one steam outlet hole.

Selon un mode de réalisation de l'invention, chaque canal d'expulsion de vapeur comporte une ouverture inférieure débouchant dans la chambre interne, et de préférence dans la première chambre de diffusion. Ces dispositions permettent l'évacuation des quelques condensats éventuellement formés dans chaque canal d'expulsion de vapeur vers la chambre interne, ce qui limite encore les risques que des gouttelettes d'eau soient projetées à l'extérieur de la tête de défroissage via l'au moins un trou de sortie de vapeur.According to one embodiment of the invention, each steam expulsion channel comprises a lower opening opening into the internal chamber, and preferably into the first diffusion chamber. These provisions allow the evacuation of any condensate that may have formed in each steam expulsion channel towards the internal chamber, which further limits the risks of water droplets being projected outside the steamer head via the at least one steam outlet hole.

Selon un mode de réalisation de l'invention, l'orifice d'évacuation de condensat est disposé à la base de la chambre interne.According to one embodiment of the invention, the condensate discharge orifice is arranged at the base of the internal chamber.

Selon un mode de réalisation de l'invention, la chambre interne comprend une paroi inférieure comportant l'orifice d'évacuation de condensat. L'orifice d'évacuation de condensat est par exemple disposé dans une portion centrale de la paroi inférieure de la chambre interne.According to one embodiment of the invention, the internal chamber comprises a lower wall comprising the condensate discharge orifice. The condensate discharge orifice is for example arranged in a central portion of the lower 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 separation of at least some of the water drops entrained by the steam flowing in the internal chamber, from the steam flow, and further limit the risks of water droplets splashing through the water. least one steam outlet hole. Indeed, the largest water droplets transported by the steam remain stuck 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 includes a condensate storage cavity arranged in the steaming head, advantageously under the lower 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 internal 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 steam expulsion channels are located at a distance from the condensate evacuation 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 flow section that gradually decreases in the direction of circulation of the vapor in the first diffusion chamber. These provisions make it possible to accelerate the steam flowing in the first diffusion chamber, and therefore to promote the blowing of the condensates away from the inlet orifice, and in particular towards the condensate discharge 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 discharge orifice 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 the first end portion and projecting into the vapor duct or into the inlet channel, for example by several millimeters. These arrangements make it possible in particular to prevent any condensate flowing along the internal wall of the inlet channel towards the inlet orifice of the inlet channel or along the internal wall of the steam duct in direction of the steam generator, to enter the return channel and fill it.

Selon un mode de réalisation de l'invention, la deuxième portion d'extrémité du canal de retour fait saillie dans le canal d'admission à proximité de l'orifice d'entrée du canal d'admission.According to one embodiment of the invention, the second end portion of the return channel protrudes into the intake channel close to the inlet orifice of the intake channel.

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 bevelled. These provisions make it possible to direct the liquid flowing in the return channel towards the tip of the latter and therefore to help relieve congestion in the return channel. In addition, this beveled shape of the return channel facilitates the passage of the vapor flow, flowing in the intake channel, on either side of this obstacle. The fact that the return channel is bevelled also partly prevents steam from entering the return channel during the first passage of steam through the steamer head (during conventional operation, the presence of water in the return channel prevents steam 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 provisions promote a flow of the condensates contained in the condensate storage cavity towards the steam conduit or the intake channel, and therefore evident an accumulation of condensates in the cavity of the condensate storage 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, le corps principal comporte une cavité interne et une ouverture d'accès débouchant dans la cavité interne, la paroi frontale fermant, de préférence de manière amovible, l'ouverture d'accès. 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 in a removable manner, the access opening. Advantageously, the internal chamber is delimited by the internal walls of the internal cavity and the front wall.

The return channel 38 can advantageously have a substantially constant passage section.

Le fonctionnement de l'appareil de défroissage 2 ainsi réalisé va maintenant être décrit.The operation of the crease-smoothing device 2 thus produced will now be described.

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 smooth a garment, he fills the liquid reservoir 4 of the base unit 3 with, for example, water, then presses a start button of the smoothing device 2. The generator steam generator 5 is then electrically supplied so as to generate steam which escapes from the steam generator 5 in the direction of the inlet orifice 18 of the inlet channel 17. The steam coming from the steam generator 5 is then flows along the inlet channel 17, enters the internal chamber 21 via the outlet orifice 19 and is distributed over a significant part of the width of the internal face of the front wall 10, because the channel d admission 17 has a flattened passage section at the level of the outlet orifice 19. Then, the vapor having entered the internal chamber 21 flows towards the base of the internal chamber 21 and around the steam expulsion channels 29, so as to heat the latter, before being redirected towards the second diffusion chamber 25 by the lower wall 35 of the internal chamber 21. Finally, the steam flows through the steam expulsion channels 29 and is diffused outside the steamer head 6, through the steam outlet holes 13.

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 elbow 22 upstream of the outlet orifice 19 induces an acceleration of the flow of steam flowing in the inlet channel 17, and therefore promotes the separation of the drops of water which are entrained by the flow of steam. , of the steam flow, while the configuration of the outlet orifice 19 ensures that the steam flow blows the separated drops of water along the front wall 10 and in the direction of the discharge orifice condensate 33, where the latter are discharged into the condensate storage cavity 36.

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 steam expulsion channels 29 and the fact that the latter comprise lower openings 32 allow any condensate formed in the steam expulsion channels 29 (such formation being limited due to the prior heating of the steam expulsion channels 29 by the steam flowing in the first diffusion chamber 23) to fall by gravity into the internal chamber 21 and to be evacuated out of the latter via the condensate discharge orifice 33.

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 condensate storage cavity 36 are then redirected to the steam conduit 7, via the return channel 38, so that the condensates slide by gravity along the steam conduit 7, and fall back into the generator. vapor 5 from the base unit 3 where they will then be re-vaporized.

La figure 8 représente une tête de défroissage 6 selon un deuxième mode de réalisation de l'invention dans lequel le circuit de retour de condensat 34 comporte un raccord 39 prévu sur la tête de défroissage 6 et relié à la cavité de stockage de condensat 36, le raccord 39 étant destiné à être raccordé à un conduit de retour relié à l'unité de base 3, et par exemple au générateur de vapeur 5, et dans lequel le canal d'admission 17 comporte au moins une nervure de guidage 41 s'étendant le long du canal d'admission 17 et configurée pour guider la vapeur s'écoulant dans le canal d'admission 17. Avantageusement, le canal d'admission 17 comporte une pluralité de nervures de guidage 41 s'étendant le long du canal d'admission 17.The figure 8 represents a steaming head 6 according to a second embodiment of the invention in which the condensate return circuit 34 comprises a connector 39 provided on the steaming head 6 and connected to the condensate storage cavity 36, the connector 39 being intended to be connected to a return duct connected to the base unit 3, and for example to the steam generator 5, and in which the inlet channel 17 comprises at least one guide rib 41 extending along of the inlet channel 17 and configured to guide the vapor flowing in the inlet channel 17. Advantageously, the channel intake 17 has a plurality of guide ribs 41 extending along the intake channel 17.

Bien entendu, l"invention n'est nullement limitée aux modes de réalisation décrits et illustrés qui n'ont été donnés qu'à titre d'exemples.Of course, the "invention is in no way limited to the embodiments described and illustrated which have been given by way of examples only.
