Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine des appareil de défroissage portatif comprenant une poignée, une tête d'émission de vapeur reliée à une extrémité supérieure de la poignée et une embase reliée à une extrémité inférieure de la poignée dans lesquelles l'embase comporte un générateur de vapeur et la poignée comprend un conduit de vapeur reliant le générateur de vapeur à moins un trou de sortie de vapeur ménagé sur la tête.The present invention relates to the field of portable steaming apparatus comprising a handle, a steam emitting head connected to an upper end of the handle and a base connected to a lower end of the handle, in which the base comprises a generator steamer and the handle includes a steam duct connecting the steam generator to at least one steam outlet hole on the head.

Etat de la techniqueState of the art

Il est connu de la demande de brevet CN106801324 , un appareil de défroissage portatif comprenant une tête d'émission de vapeur reliée à une extrémité supérieure de la poignée, la tête d'émission de vapeur comportant une face de traitement, munie d'orifices de sortie de vapeur, destinée à venir verticalement en regard d'un vêtement à défroisser lorsque l'appareil est tenu avec sa poignée orientée sensiblement verticalement. L'appareil divulgué dans ce document comprend une chambre de vaporisation ménagée dans l'embase et relié à la tête par un conduit de vapeur passant dans la poignée.It is known from the patent application CN106801324 , a portable steamer comprising a steam emitting head connected to an upper end of the handle, the steam emitting head comprising a treatment face, provided with steam outlet orifices, intended to come vertically into look of a garment to be smoothed when the device is held with its handle oriented substantially vertically. The apparatus disclosed in this document comprises a vaporization chamber arranged in the base and connected to the head by a vapor conduit passing through the handle.

Un tel appareil présente l'avantage de posséder un générateur de vapeur qui est disposé dans l'embase de sorte que l'équilibre des masses ainsi procuré offre une bonne ergonomie d'utilisation. En effet, le poids du générateur étant situé sous la poignée, ce dernier ne génère pas un couple ayant tendance à tordre le poignet de l'utilisateur lorsque l'appareil est maintenu verticalement.Such a device has the advantage of having a steam generator which is arranged in the base so that the balance of the masses thus procured offers good ergonomics of use. Indeed, the weight of the generator being located under the handle, the latter does not generate a torque tending to twist the user's wrist when the device is held vertically.

Cependant, un tel appareil nécessite le passage d'un conduit de vapeur à l'intérieur de la poignée qui a tendance à chauffer la poignée. De plus, le conduit de vapeur, qui s'étend alors entre l'embase et la tête de l'appareil, présente une longueur importante de sorte que la vapeur qui chemine à l'intérieur de ce conduit de vapeur à tendance à se refroidir, ce qui peut provoquer l'apparition de condensats. Ces condensats sont ensuite projetés en même temps que le flux de vapeur à l'extérieur de l'appareil et peuvent venir tacher le linge ou bruler l'utilisateur.However, such a device requires the passage of a steam pipe inside the handle which tends to heat the handle. In addition, the steam duct, which then extends between the base and the head of the device, has a significant length so that the steam which travels inside this steam duct tends to cool , which can cause the appearance of condensate. This condensate is then projected at the same time as the flow of steam outside the appliance and can stain the laundry or burn the user.

Les plots de fixation 90 constituent les seuls points de contact direct entre la poignée 2 et le manchon 9, une couche d'air étant ménagée entre la surface interne de la poignée 2 et la paroi du manchon 9.As can be seen on the figures 3 and 4 , the sleeve 9 comprises two fixing studs 90 projecting from the wall of the sleeve 9 and coming into contact with the internal surface of the handle 2, the two fixing studs 90 making it possible to fix the sleeve 9 by gluing or by screwing onto the handle 2. The fixing studs 90 constitute the only direct contact points between the handle 2 and the sleeve 9, a layer of air being provided between the internal surface of the handle 2 and the wall of the sleeve 9.

Conformément à la figure 2, le conduit d'alimentation 7 est disposé à l'extérieur du manchon 9, ce dernier comprenant, au niveau de son extrémité supérieure, une platine de fixation 91 venant en regard de la face avant de la poignée 2 et sur laquelle est fixé le distributeur 70 associé à la gâchette 71.In accordance with the picture 2 , the supply duct 7 is disposed outside the sleeve 9, the latter comprising, at its upper end, a fixing plate 91 coming opposite the front face of the handle 2 and on which is fixed the distributor 70 associated with trigger 71.

Le fonctionnement de l'appareil va maintenant être décrit.The operation of the apparatus will now be described.

Lorsque l'utilisateur souhaite utiliser l'appareil, il remplit le réservoir 6 d'eau puis branche l'appareil sur le réseau électrique. La résistance 41 électrique de la chambre de vaporisation 40 est alors alimentée en courant de sorte que sa température atteint rapidement une température de consigne définie par le thermostat.When the user wishes to use the device, he fills the tank 6 with water and then connects the device to the electrical network. The electrical resistor 41 of the vaporization chamber 40 is then supplied with current so that its temperature quickly reaches a setpoint temperature defined by the thermostat.

Lorsque l'utilisateur souhaite utiliser l'appareil, il presse sur la gâchette 71, ce qui a pour effet d'ouvrir la soupape et de permettre l'écoulement d'eau au travers du conduit d'alimentation 7 vers la chambre de vaporisation 40. La vapeur produite par la chambre de vaporisation 40 s'échappe ensuite au travers du conduit de vapeur 8 en direction de la chambre de diffusion de vapeur 52 ménagée dans la tête 3 puis sort par les trous 51 de sortie de vapeur ménagés sur la face de traitement 50.When the user wishes to use the device, he presses the trigger 71, which has the effect of opening the valve and allowing the flow of water through the supply conduit 7 to the vaporization chamber 40. The steam produced by the vaporization chamber 40 then escapes through the steam conduit 8 in the direction of the vapor diffusion chamber 52 provided in the head 3 then exits through the steam outlet holes 51 provided on the treatment face 50.

La présence du manchon 9 autour du conduit de vapeur 8 forme une barrière thermique qui limite le transfert thermique entre la poignée 2 et le conduit de vapeur 8 et évite un échauffement trop important des parois de la poignée 2. Ainsi, un tel manchon 9 permet d'éviter à l'utilisateur d'avoir une sensation désagréable liée à un échauffement important de la poignée 2, voire de se bruler. De plus, un tel manchon 9 permet également d'éviter un refroidissement du conduit de vapeur 8 au niveau de la poignée 2, ce qui permet de réduire le risque d'apparition de condensats dans le conduit de vapeur 8. On limite ainsi le risque que des gouttelettes d'eau ne soient projetées au travers des trous 51 de sortie de vapeur et viennent tacher le linge, voir bruler l'utilisateur.The presence of the sleeve 9 around the steam duct 8 forms a thermal barrier which limits the heat transfer between the handle 2 and the steam duct 8 and prevents excessive heating of the walls of the handle 2. Thus, such a sleeve 9 allows to prevent the user from having an unpleasant sensation linked to significant heating of the handle 2, or even from burning himself. In addition, such a sleeve 9 also makes it possible to avoid cooling of the steam conduit 8 at the level of the handle 2, which makes it possible to reduce the risk of condensate appearing in the steam conduit 8. The risk is thus limited that water droplets are projected through the steam outlet holes 51 and stain the laundry, or even burn the user.

L'appareil ainsi réalisé présente donc l'avantage de permettre une ergonomie d'utilisation améliorer en limitant l'échauffement de la poignée tout en proposant des performances améliorées, en limitant le risque de projection de gouttelettes d'eau par les trous de sortie de vapeur.The device thus produced therefore has the advantage of allowing improved ergonomics of use by limiting the heating of the handle while offering improved performance, by limiting the risk of projection of water droplets through the exit holes of steam.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments. sans sortir pour autant du domaine de protection de l'invention. L'invention est définie par la revendication indépendante.Of course, the 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. without thereby departing from the scope of protection of the invention. The invention is defined by the independent claim.

Ainsi, dans une variante de réalisation non représentée, la chambre de vaporisation instantanée pourra être remplacée par un générateur de vapeur sous pression muni d'un orifice sortie équipé d'une électrovanne permettant de contrôler l'émission de vapeur au travers du conduit de vapeur, l'ouverture de l'électrovanne étant alors pilotée par la gâchette. Dans cette variante de réalisation, le générateur de vapeur pourra être alimentée en eau au moyen d'une pompe reliée au réservoir.Thus, in a variant embodiment not shown, the instantaneous vaporization chamber can be replaced by a pressurized steam generator provided with an outlet orifice equipped with a solenoid valve making it possible to control the emission of steam through the steam conduit. , the opening of the solenoid valve then being controlled by the trigger. In this alternative embodiment, the steam generator may be supplied with water by means of a pump connected to the tank.
