Definitions
- the present invention relates to an apparatus for drying and / or shaping hair, more particularly a hair dryer having a removable air inlet grille.
- Hair dryers for private or professional use generally comprise a housing provided with a handle and equipped with air circulation means between an inlet grille in the housing and an outlet port of the latter, and means heating the air blown.
- the air circulation means comprise a fan driven by an electric motor and the heating means comprise an electrical resistance arranged in the air flow.
- the air inlet grille is made generally based on a perforated sheet or cloth and lets in the air while retaining the hair, pills or other impurities present in the air sucked in order to protect the air. internal parts of the device.
- Such an inlet grille must be breathable, while being able to stop the particles of larger size than that of its air passage holes.
- the problem that often arises with these devices is that the particles or fibers sucked by the device are fixed on the outer surface of the grid or even enter its air passage holes by closing them. Thus, to ensure proper operation of the apparatus, it is necessary to carry out a regular cleaning of the grid, which implies a dismountable construction thereof.
- Hair dryers having rear grids fixed by means of clips forcibly inserted into housing lumens are known in the state of the art. This type of attachment is however neither effective nor ergonomic.
- the document WO 89/08414 discloses a hair dryer having a multi-part housing containing a motor fan, a heating resistor, a nozzle attached to the air outlet end, the air inlet end being protected by a removable grid.
- the grid is mounted at the end of the housing using a screw or bayonet attachment.
- This removable grid mounting solution requires that the grid be prominent and provided with gripping grooves on its periphery, while imposing a specific shape for the rear portion of the housing.
- This type of attachment requires a prior orientation of the grid before its introduction into the device, followed by a rotational movement and clamping for attachment to the housing, which is not very ergonomic for the user, while also limiting the design possibilities of the housing to forms of revolution.
- the hairdryer comprises a rear grid device removably mounted relative to the housing, the grid being carried by a frame fixed to the housing by two side latches whose spring hooks fit into the slots in the frame of the grid .
- the disassembly of this device requires manipulation with both hands of the user to perform the steps of unlocking and removing the grid.
- this removable grid fixing solution does not have good ergonomics.
- a tubular hair curler comprises a metal washer disposed at its upstream end which is attracted by a magnet fixed, him, inside a hose blowing hot air to the hair.
- the connection of the two parts is done using a telescopic mounting and a magnet of sufficient size to avoid the risk of removal of the connection, the force of the air flow being contrary to that of the magnetic field of the connection device.
- This connection device is more difficult to manipulate and is more expensive.
- the object of the present invention is to overcome the aforementioned drawbacks and to provide a hairdryer having an air inlet grille removably attached by implementing a quick connection system, convenient, reliable, easy to use , allowing good ergonomics, without imposing any limitation in the shapes of the housing of the apparatus.
- Another object of the invention is a hairdryer provided with a removable air inlet grille that can be mounted and disassembled very easily, while ensuring effective attachment to the housing and integrating well into the device design.
- Another object of the invention is a hair dryer having a dismountable air intake grille made economically, while allowing reliable operation of the apparatus comprising it.
- a hair dryer having a tubular housing including an air inlet end, an air outlet end, and means for heating and circulating an air flow between the end of the air.
- input and the output end the input end including an opening whose edge cooperates with the periphery of a grid mounted to dismount relative to the housing by means of a connection system, because the connection system comprises a magnetic coupling arranged substantially at the same axial level as that of the edge of the opening or being protruding relative thereto so that the periphery of the grid fits into the edge of the opening at the level of their free face vis-à-vis.
- removable grid is understood a grid which can be separated from the housing, especially for cleaning, or remaining attached to the latter for example by a hinge, or being removable.
- the apparatus comprises a magnetic coupling connection system arranged so as to allow an immediate and stable contact of the gate in the air inlet opening of the housing.
- This connection system comprises a magnetic coupling arranged sufficiently on the surface to allow the contour of the grid and the edge of the opening of the housing to come into contact when they are close together and this in an intuitive manner, virtually without prior guidance. This is suitable for fixing a thin part such as a removable grid in the air inlet mouth of a hair dryer.
- the periphery of the grid and the edge of the opening are preferably made to interlock at the connection location.
- the contact surface of the periphery of the grid and that of the edge of the opening each have a conical shape.
- Such magnetic attachment by interlocking ensures the immobilization of the gate by attraction in one direction, that of the magnetic field, the gate and the housing being shaped so that, when attracted by the magnets, the gate can not move according to the other two translation directions, perpendicular to the first.
- the grid is brought into contact with a housing provided for this purpose at the air inlet opening of the housing, it is pressed and held in position.
- the grid thus fixed can then be moved by the user with a view to its separation from the housing, for example by pulling in a direction opposite to that of attraction of the magnets or by tilting along an axis situated in the plane of the coupling.
- Such a fastening system ensures a rapid installation of the grid and a separation also fast compared to the housing of the device, thanks to the magnetic attraction existing between the two, the magnetic force being established so that it is strong enough to hold the weight of the grid, but weak enough that it can be easily detached by hand.
- the magnetic coupling comprises at least one magnet belonging to the housing and the direction of its magnetic field is parallel to the longitudinal axis of the housing.
- the magnetic coupling comprises at least one magnet cooperating with a magnetizable piece (one comprises a piece capable of being magnetized when it is placed in a magnetic field, for example a part made of a ferromagnetic material) or with another magnet vis-a-vis to face.
- the magnet of the coupling could be placed on the periphery of the grid, but it is preferred to install it in the housing of the apparatus in order to lighten the grid.
- the apparatus comprises means for producing an air flow oriented in the direction of the longitudinal axis of the housing. The magnetic field is thus oriented in the same direction as that of the flow of air to better press the grid on the housing and allow the use of a magnetic field of less intensity.
- the magnetic coupling is arranged on the edge or at the center of the opening of the air inlet end of the housing.
- Such an arrangement allows the installation of the magnetic coupling in areas which do not interfere with the entry of air into the housing, the center area having a size comparable to that of the fan axis and that of the edge at a distance of crown diameter equal to or greater than that of the fan wheel.
- the grid comprises a frame that aligns with the tangent to the surface of the housing at the point of assembly.
- the frame of the grid has a non-circular and / or non-coplanar contour cooperating with the walls of the opening of the housing.
- the grid engages with its periphery in the edge of the opening of the complementary contour case.
- a non-circular and / or non-coplanar contour of its free face vis-à-vis that of the edge can first guide the grid in the opening of the housing and then by sliding until it locks in place. position by magnetic coupling. It is thus possible to choose a planar contour having a non-circular shape fitting into a corresponding shape of the opening of the housing, and / or having a raised shape thus comprising at least one protuberance or a non-planar face offering a better grip. hand and a practical orientation of the grid before it is placed on the case.
- the walls of the opening of the housing have at least one projecting portion carrying a magnet or a magnetizable piece.
- the housing can then include a recessed portion provided with a magnet or a magnetizable piece vis-à-vis.
- the magnet is arranged in a cavity formed at the top of the projecting portion cooperating with a protuberance of the grid.
- the protrusion of the grid may be a protruding magnetizable piece or a protruding permanent magnet.
- the walls of the opening of the housing have two projections symmetrical with respect to a median plane passing through the longitudinal axis of the housing.
- the grid is thus autocentered by the two opposite projecting parts of the walls of the housing, which allows its rapid interlocking.
- the grid comprises two magnets cooperating with those facing the walls of the opening of the housing.
- magnets only in the receiving housing of the grid in the housing, these magnets then cooperating with a metal grid and / or with a metal frame of the latter. It is however preferred to arrange magnets on the grid, or on the frame of the grid, and also on the periphery of the housing housing, this to ensure a more robust attachment, especially in the proximity of the magnetic fields of the electric motor of the apparatus .
- two magnets facing each other define the correct position of the grid, for example grid positioned at the place, the position of the grid upside down being automatically refused by the repulsion force of the magnets, which constitutes a confirmation the proper placement of the grille in the housing.
- the grid comprises two magnets having different polarities.
- This solution is an effective keying system facilitating the establishment of a non-symmetrical shape grid or whose direction of arrangement relative to the air flow (at the place or upside down) is very important for a efficient operation of the device.
- the grid and / or the housing comprise means making it easier to grip the grid.
- These means may be a protuberance on the frame of the grid possibly cooperating with a corresponding notch of the housing, a notch in the box cooperating with the frame of the grid, or a re-entrant corner of the surface of the grid, away from the magnetic lever fastener for overcoming the magnetic force of the fastener.

Abstract
Description
La présente invention concerne un appareil de séchage et/ou de mise en forme des cheveux, plus particulièrement un sèche-cheveux comportant une grille d'entrée d'air démontable.The present invention relates to an apparatus for drying and / or shaping hair, more particularly a hair dryer having a removable air inlet grille.
Les sèche-cheveux à usage privé ou professionnel comprennent généralement un boîtier muni d'une poignée et équipé de moyens de circulation de l'air entre une grille d'entrée dans le boîtier et un orifice de sortie de ce dernier, ainsi que de moyens de chauffage de l'air soufflé. Les moyens de circulation de l'air comprennent un ventilateur entraîné par un moteur électrique et les moyens de chauffage comprennent une résistance électrique agencée dans le flux d'air.Hair dryers for private or professional use generally comprise a housing provided with a handle and equipped with air circulation means between an inlet grille in the housing and an outlet port of the latter, and means heating the air blown. The air circulation means comprise a fan driven by an electric motor and the heating means comprise an electrical resistance arranged in the air flow.
La grille d'entrée d'air est réalisée généralement à base d'une feuille perforée ou d'un tissu et laisse entrer l'air tout en retenant les cheveux, les bouloches ou autres impuretés présentes dans l'air aspiré afin de protéger les parties internes de l'appareil. Une telle grille d'entrée doit ainsi être perméable à l'air, tout en étant apte à arrêter les particules de taille supérieure à celle de ses orifices de passage d'air. Le problème qui se pose souvent avec ces appareils est que les particules ou fibres aspirées par l'appareil se fixent sur la surface externe de la grille ou pénètrent même dans ses orifices de passage d'air en les obturant. Ainsi, pour assurer un fonctionnement correct de l'appareil, il faut procéder à un nettoyage régulier de la grille, ce qui implique une construction démontable de celle-ci.The air inlet grille is made generally based on a perforated sheet or cloth and lets in the air while retaining the hair, pills or other impurities present in the air sucked in order to protect the air. internal parts of the device. Such an inlet grille must be breathable, while being able to stop the particles of larger size than that of its air passage holes. The problem that often arises with these devices is that the particles or fibers sucked by the device are fixed on the outer surface of the grid or even enter its air passage holes by closing them. Thus, to ensure proper operation of the apparatus, it is necessary to carry out a regular cleaning of the grid, which implies a dismountable construction thereof.
On connaît dans l'état de la technique des sèche-cheveux ayant des grilles arrière fixées à l'aide de clips insérés de force dans des lumières du boîtier. Ce type de fixation n'est toutefois ni efficace ni ergonomique.Hair dryers having rear grids fixed by means of clips forcibly inserted into housing lumens are known in the state of the art. This type of attachment is however neither effective nor ergonomic.

Le but de la présente invention est de remédier aux inconvénients précités et de proposer un sèche-cheveux comportant une grille d'entrée d'air fixée de manière démontable en mettant en oeuvre un système de connexion rapide, pratique, fiable, simple d'utilisation, permettant une bonne ergonomie, sans imposer de limitation dans les formes du boîtier de l'appareil.The object of the present invention is to overcome the aforementioned drawbacks and to provide a hairdryer having an air inlet grille removably attached by implementing a quick connection system, convenient, reliable, easy to use , allowing good ergonomics, without imposing any limitation in the shapes of the housing of the apparatus.
Un autre but de l'invention est un sèche-cheveux muni d'une grille d'entrée d'air démontable pouvant être montée et démontée de manière très aisée, tout en assurant une fixation efficace au boîtier et en s'intégrant bien dans le design de l'appareil.Another object of the invention is a hairdryer provided with a removable air inlet grille that can be mounted and disassembled very easily, while ensuring effective attachment to the housing and integrating well into the device design.
Un autre but de l'invention est un sèche-cheveux comportant une grille d'entrée d'air démontable réalisée de manière économique, tout en permettant un fonctionnement fiable de l'appareil la comportant.Another object of the invention is a hair dryer having a dismountable air intake grille made economically, while allowing reliable operation of the apparatus comprising it.
Ces buts sont atteints avec un sèche-cheveux comportant un boîtier tubulaire comprenant une extrémité d'entrée d'air, une extrémité de sortie d'air, ainsi que des moyens pour réchauffer et faire circuler un flux d'air entre l'extrémité d'entrée et l'extrémité de sortie, l'extrémité d'entrée comprenant une ouverture dont la bordure coopère avec la périphérie d'une grille montée démontable par rapport au boîtier moyennant un système de connexion, du fait que le système de connexion comporte un couplage magnétique agencé sensiblement au même niveau axial que celui de la bordure de l'ouverture ou en étant protubérant par rapport à celui-ci de manière à ce que la périphérie de la grille s'emboîte dans la bordure de l'ouverture au niveau de leur face libre en vis-à-vis.These objects are achieved with a hair dryer having a tubular housing including an air inlet end, an air outlet end, and means for heating and circulating an air flow between the end of the air. input and the output end, the input end including an opening whose edge cooperates with the periphery of a grid mounted to dismount relative to the housing by means of a connection system, because the connection system comprises a magnetic coupling arranged substantially at the same axial level as that of the edge of the opening or being protruding relative thereto so that the periphery of the grid fits into the edge of the opening at the level of their free face vis-à-vis.
Par grille démontable on comprend une grille qui peut être désolidarisée du boîtier, notamment en vue de son nettoyage, soit en restant attachée à ce dernier par exemple par une charnière, soit en étant amovible.By removable grid is understood a grid which can be separated from the housing, especially for cleaning, or remaining attached to the latter for example by a hinge, or being removable.
Selon l'invention, l'appareil comporte un système de connexion par couplage magnétique agencé de manière à permettre une mise en contact immédiate et stable de la grille dans l'ouverture d'entrée d'air du boîtier. Ce système de connexion comprend un couplage magnétique agencé suffisamment en surface pour permettre au contour de la grille et à la bordure de l'ouverture du boîtier de venir en contact lorsqu'elles sont rapprochées et ceci de manière intuitive, pratiquement sans orientation préalable. Ceci convient à la fixation d'une pièce de fine épaisseur telle une grille démontable dans l'embouchure d'entrée d'air d'un sèche-cheveux.According to the invention, the apparatus comprises a magnetic coupling connection system arranged so as to allow an immediate and stable contact of the gate in the air inlet opening of the housing. This connection system comprises a magnetic coupling arranged sufficiently on the surface to allow the contour of the grid and the edge of the opening of the housing to come into contact when they are close together and this in an intuitive manner, virtually without prior guidance. This is suitable for fixing a thin part such as a removable grid in the air inlet mouth of a hair dryer.
La périphérie de la grille et la bordure de l'ouverture sont réalisées de préférence à emboîtement réciproque à l'endroit du raccordement. A titre d'exemple, la surface de contact de la périphérie de la grille et celle de la bordure de l'ouverture ont chacune une forme conique. Une telle fixation magnétique par emboîtement assure l'immobilisation de la grille par attraction dans une direction, celle du champ magnétique, la grille et le boîtier étant conformés de manière à ce que, lorsque attirée par les aimants, la grille ne puisse pas se déplacer selon les deux autres directions de translation, perpendiculaires à la première. Ainsi, lorsque la grille est amenée en contact avec un logement prévu à cet effet au niveau de l'ouverture d'entrée d'air du boîtier, elle est plaquée et maintenue en position. La grille ainsi fixée pourra ensuite être déplacée par l'utilisateur en vue de sa désolidarisation par rapport au boîtier, par exemple en effectuant une traction en un sens contraire à celui d'attraction des aimants ou par basculement selon un axe situé dans le plan du couplage.The periphery of the grid and the edge of the opening are preferably made to interlock at the connection location. For example, the contact surface of the periphery of the grid and that of the edge of the opening each have a conical shape. Such magnetic attachment by interlocking ensures the immobilization of the gate by attraction in one direction, that of the magnetic field, the gate and the housing being shaped so that, when attracted by the magnets, the gate can not move according to the other two translation directions, perpendicular to the first. Thus, when the grid is brought into contact with a housing provided for this purpose at the air inlet opening of the housing, it is pressed and held in position. The grid thus fixed can then be moved by the user with a view to its separation from the housing, for example by pulling in a direction opposite to that of attraction of the magnets or by tilting along an axis situated in the plane of the coupling.
Un tel système de fixation assure une mise en place rapide de la grille et une désolidarisation également rapide par rapport au boîtier de l'appareil, grâce à l'attraction magnétique existant entre les deux, la force magnétique étant établie de manière à ce qu'elle soit suffisamment forte pour retenir le poids de la grille, mais suffisamment faible pour qu'elle puisse être facilement détachée à la main.Such a fastening system ensures a rapid installation of the grid and a separation also fast compared to the housing of the device, thanks to the magnetic attraction existing between the two, the magnetic force being established so that it is strong enough to hold the weight of the grid, but weak enough that it can be easily detached by hand.
De préférence, le couplage magnétique comporte au moins un aimant appartenant au boîtier et la direction de son champ magnétique est parallèle à l'axe longitudinal du boîtier.Preferably, the magnetic coupling comprises at least one magnet belonging to the housing and the direction of its magnetic field is parallel to the longitudinal axis of the housing.
Le couplage magnétique comporte au moins un aimant coopérant avec une pièce magnétisable (on comprend une pièce apte à être aimantée lorsqu'elle est placée dans un champ magnétique, par exemple une pièce réalisée en un matériau ferromagnétique) ou avec un autre aimant en vis-à-vis. On pourrait placer l'aimant du couplage sur la périphérie de la grille, mais on préfère toutefois l'installer dans le boîtier de l'appareil afin d'alléger la grille. L'appareil comporte des moyens de production d'un flux d'air orienté selon la direction de l'axe longitudinal du boîtier. Le champ magnétique est ainsi orienté dans un même sens que celui d'écoulement du flux d'air pour mieux plaquer la grille sur le boîtier et permettre l'utilisation d'un champ magnétique de moindre intensité.The magnetic coupling comprises at least one magnet cooperating with a magnetizable piece (one comprises a piece capable of being magnetized when it is placed in a magnetic field, for example a part made of a ferromagnetic material) or with another magnet vis-a-vis to face. The magnet of the coupling could be placed on the periphery of the grid, but it is preferred to install it in the housing of the apparatus in order to lighten the grid. The apparatus comprises means for producing an air flow oriented in the direction of the longitudinal axis of the housing. The magnetic field is thus oriented in the same direction as that of the flow of air to better press the grid on the housing and allow the use of a magnetic field of less intensity.
De préférence, le couplage magnétique est agencé sur la bordure ou au centre de l'ouverture de l'extrémité d'entrée d'air du boîtier.Preferably, the magnetic coupling is arranged on the edge or at the center of the opening of the air inlet end of the housing.
Un tel agencement permet l'installation du couplage magnétique dans des zones qui ne gênent pas l'entrée d'air dans le boîtier, la zone du centre ayant une dimension comparable à celle de l'axe du ventilateur et celle de la bordure à une couronne de diamètre égal ou supérieur à celui de la roue du ventilateur.Such an arrangement allows the installation of the magnetic coupling in areas which do not interfere with the entry of air into the housing, the center area having a size comparable to that of the fan axis and that of the edge at a distance of crown diameter equal to or greater than that of the fan wheel.
Avantageusement, la grille comporte un cadre qui s'aligne sur la tangente à la surface du boîtier au point de l'assemblage.Advantageously, the grid comprises a frame that aligns with the tangent to the surface of the housing at the point of assembly.
Cette solution permet de placer la grille et ses fixations dans la continuité des formes du boîtier et d'obtenir ainsi un appareil à grille démontable, avec un design avantageux.This solution makes it possible to place the grid and its fasteners in the continuity of the shapes of the case and thus to obtain a device with removable grid, with an advantageous design.
Avantageusement, le cadre de la grille a un contour non circulaire et/ou non coplanaire coopérant avec les parois de l'ouverture du boîtier.Advantageously, the frame of the grid has a non-circular and / or non-coplanar contour cooperating with the walls of the opening of the housing.
La grille s'emboîte avec sa périphérie dans la bordure de l'ouverture du boîtier de contour complémentaire. Un tel contour non circulaire et/ou non coplanaire de sa face libre en vis-à-vis de celle de la bordure permet de guider d'abord visuellement la grille dans l'ouverture du boîtier et ensuite par glissement jusqu'à son blocage en position par le couplage magnétique. On peut ainsi choisir un contour plan ayant une forme non circulaire s'emboîtant dans une forme correspondante de l'ouverture du boîtier, et/ou ayant une forme en relief comportant donc au moins une protubérance ou une face non plane offrant une meilleure prise en main et une orientation pratique de la grille avant sa mise en place sur le boîtier.The grid engages with its periphery in the edge of the opening of the complementary contour case. Such a non-circular and / or non-coplanar contour of its free face vis-à-vis that of the edge can first guide the grid in the opening of the housing and then by sliding until it locks in place. position by magnetic coupling. It is thus possible to choose a planar contour having a non-circular shape fitting into a corresponding shape of the opening of the housing, and / or having a raised shape thus comprising at least one protuberance or a non-planar face offering a better grip. hand and a practical orientation of the grid before it is placed on the case.
Avantageusement, les parois de l'ouverture du boîtier présentent au moins une partie saillante portant un aimant ou une pièce magnétisable.Advantageously, the walls of the opening of the housing have at least one projecting portion carrying a magnet or a magnetizable piece.
Cette solution permet de pré orienter la grille, à distance par rapport à son logement, de manière très intuitive, pratiquement sans devoir regarder la grille ou son logement dans le boîtier. L'attraction magnétique exercée au niveau d'une protubérance du logement assure ainsi une mise en place de la partie en vis-à-vis de la grille, forçant les autres côtés de celle-ci à s'aligner par la suite autour de la fixation magnétique. Dans une variante, c'est la grille qui comporte une telle protubérance à aimant, le boîtier pouvant alors comporter une partie en creux munie d'un aimant ou d'une pièce magnétisable en vis-à-vis.This solution makes it possible to pre-orient the grid, remotely with respect to its housing, in a very intuitive way, practically without having to look at the grid or its housing in the housing. The magnetic attraction exerted at a protuberance of the housing thus ensures that the part opposite the grid is positioned, forcing the other sides of the latter to align later thereafter. magnetic fixation. In a variant, it is the grid that has such a protuberance magnet, the housing can then include a recessed portion provided with a magnet or a magnetizable piece vis-à-vis.
De préférence, l'aimant est agencé dans une cavité pratiquée au sommet de la partie saillante coopérant avec une protubérance de la grille.Preferably, the magnet is arranged in a cavity formed at the top of the projecting portion cooperating with a protuberance of the grid.
La protubérance de la grille peut être une pièce magnétisable protubérante ou un aimant permanent protubérant. Un tel assemblage de parties protubérantes et cavités assure à la fois un meilleur emboîtement de la grille et du boîtier, pour une meilleure tenue de la fixation magnétique, et une continuité des parois du boîtier et de la grille, les parties de fixation étant rendues non visibles.The protrusion of the grid may be a protruding magnetizable piece or a protruding permanent magnet. Such an assembly of protruding parts and cavities ensures both a better interlocking of the grid and the housing, for a better holding of the magnetic attachment, and a continuity of the walls of the housing and the grid, the fixing parts being rendered invisible.
Avantageusement, les parois de l'ouverture du boîtier présentent deux parties saillantes symétriques par rapport à un plan médian passant par l'axe longitudinal du boîtier.Advantageously, the walls of the opening of the housing have two projections symmetrical with respect to a median plane passing through the longitudinal axis of the housing.
La grille est ainsi autocentrée par les deux parties saillantes opposées des parois du boîtier, ce qui permet son emboîtement rapide.The grid is thus autocentered by the two opposite projecting parts of the walls of the housing, which allows its rapid interlocking.
De préférence, la grille comporte deux aimants coopérant avec ceux en vis-à-vis des parois de l'ouverture du boîtier.Preferably, the grid comprises two magnets cooperating with those facing the walls of the opening of the housing.
On aurait pu, certes, agencer des aimants uniquement dans le logement de réception de la grille dans le boîtier, ces aimants coopérant alors avec une grille métallique et/ou avec un cadre métallique de cette dernière. On préfère toutefois agencer des aimants sur la grille, ou sur le cadre de la grille, et également sur le pourtour du logement du boîtier, ceci pour assurer une fixation plus robuste, surtout dans la proximité des champs magnétiques du moteur électrique de l'appareil. De surcroît, deux aimants se faisant face définissent la position correcte de la grille, par exemple grille positionnée à l'endroit, la position de la grille à l'envers étant automatiquement refusée par la force de répulsion des aimants, ce qui constitue une confirmation de la bonne mise en place de la grille dans le boîtier.It would have been possible, certainly, to arrange magnets only in the receiving housing of the grid in the housing, these magnets then cooperating with a metal grid and / or with a metal frame of the latter. It is however preferred to arrange magnets on the grid, or on the frame of the grid, and also on the periphery of the housing housing, this to ensure a more robust attachment, especially in the proximity of the magnetic fields of the electric motor of the apparatus . In addition, two magnets facing each other define the correct position of the grid, for example grid positioned at the place, the position of the grid upside down being automatically refused by the repulsion force of the magnets, which constitutes a confirmation the proper placement of the grille in the housing.
Dans une variante avantageuse de l'invention, la grille comporte deux aimants ayant des polarités différentes.In an advantageous variant of the invention, the grid comprises two magnets having different polarities.
Cette solution constitue un système détrompeur efficace facilitant la mise en place d'une grille de forme non symétrique ou dont le sens d'agencement par rapport au flux d'air (à l'endroit ou à l'envers) est très important pour un fonctionnement efficace de l'appareil.This solution is an effective keying system facilitating the establishment of a non-symmetrical shape grid or whose direction of arrangement relative to the air flow (at the place or upside down) is very important for a efficient operation of the device.
Avantageusement, la grille et/ou le boîtier comprennent des moyens permettant de faciliter la préhension de la grille.Advantageously, the grid and / or the housing comprise means making it easier to grip the grid.
Ces moyens peuvent être une protubérance sur le cadre de la grille pouvant éventuellement coopérer avec une encoche correspondante du boîtier, soit une encoche dans le boiter coopérant avec le cadre de la grille, voire un coin rentrant de la surface de la grille, éloigné de la fixation magnétique formant levier pour vaincre la force magnétique de l'attache.These means may be a protuberance on the frame of the grid possibly cooperating with a corresponding notch of the housing, a notch in the box cooperating with the frame of the grid, or a re-entrant corner of the surface of the grid, away from the magnetic lever fastener for overcoming the magnetic force of the fastener.
Dans un mode avantageux de réalisation de l'invention, le sèche-cheveux comporte des moyens permettant d'écarter les éléments de la fixation magnétique.In an advantageous embodiment of the invention, the hair dryer comprises means for removing the elements of the magnetic attachment.
Ces moyens, internes ou externes au boîtier, permettent, lorsque actionnés, d'écarter les aimants entre eux ou l'aimant de sa pièce magnétisable en vis-à-vis afin de diminuer l'effort d'extraction de la grille. On peut obtenir ce résultat en modifiant la distance entre les aimants (voire entre un aimant et une pièce magnétisable) et/ou leur polarité l'un par rapport à l'autre.These means, internal or external to the housing, allow, when actuated, to move the magnets between them or the magnet of its magnetizable piece vis-à-vis to reduce the extraction force of the grid. This can be achieved by changing the distance between the magnets (or even between a magnet and a magnetizable part) and / or their polarity with respect to each other.

Des raccords 9 à une alimentation électrique assurent l'alimentation en énergie de l'appareil. La mise en marche, l'arrêt de l'appareil et le choix de son mode de fonctionnement se font en actionnant l'un des interrupteurs 5,6,7 situés sur la poignée 4 de l'appareil. Une lampe 8 témoignant de la mise en marche de l'appareil est disposée également sur la poignée 4. La poignée 4 se prolonge par un crochet 10 permettant le rangement de l'appareil lorsqu'il n'est pas utilisé.
Le sèche-cheveux comporte également une buse 11 fixée à l'extrémité de sortie d'air 3 et permettant de concentrer le flux d'air soufflé par l'appareil. La buse 11 peut être fixée de manière permanente à l'extrémité de sortie d'air 3 du boîtier 1 ou elle peut également être montée amovible par rapport au boîtier 1, par exemple par une fixation à baïonnette, par un assemblage forcé, par un assemblage comportant des crochets élastiques coopérant avec des fentes en vis-à-vis, etc., notamment en vue de son remplacement par un autre accessoire permettant de donner une autre forme au flux d'air.The hairdryer also has a
L'appareil comporte par ailleurs une grille 14 agencée à l'extrémité d'entrée d'air 2 du boîtier 1 ayant le rôle de filtrer l'air en retenant les impuretés de taille supérieure à celle de ses orifices. Cette grille 14 est fixée de manière démontable par rapport au boîtier 1 du sèche-cheveux.The apparatus also comprises a
Selon l'invention, le sèche-cheveux comporte une grille 14 démontable dont le contour est conformé pour s'emboîter dans les parois 17 de l'ouverture 12 du boîtier 1, la grille étant fixée au boîtier 1 par un couplage magnétique 15 (
Dans l'exemple représenté aux figures, la grille 14 comporte une partie centrale 20 tenue par un cadre 21. La partie centrale 20 est une portion de sphère réalisée en une feuille métallique perforée munie d'orifices de passage (non représentés sur les dessins) de l'air ambiant lorsqu'il est aspiré par le ventilateur de l'appareil. Le ventilateur est agencé à l'intérieur du boîtier 1, derrière une grille de protection 18 montée à demeure sur le boîtier en aval de l'ouverture 12 dans le sens de circulation du flux d'air. La partie centrale 20 de la grille est tenue par un cadre 21, réalisé par exemple en une matière plastique, la partie centrale 20 de la grille comportant sur son pourtour des languettes de fixation (non visibles sur les dessins) passant par des orifices pratiqués sur la périphérie interne du cadre 21. Le cadre 21 a une forme ondulée comportant deux concavités 22 latérales symétriques reliées par deux parties en arc 23 supérieure et inférieure symétriques et coplanaires. Deux aimants permanents 25 sont fixés sur la périphérie interne du cadre 21, les aimants 25 ont une forme cylindrique et sont protubérants en la partie centrale des concavités 22, en étant montés au fond de celles-ci. Les aimants peuvent par exemple être fixés par collage sur la périphérie interne du cadre 21.In the example shown in the figures, the

En fonctionnement, l'utilisateur met en marche l'appareil, il réalise le séchage de la chevelure, ensuite il arrête l'appareil. Après plusieurs opérations successives de séchage des cheveux, l'utilisateur détache la grille 14 en appuyant avec le pouce sur la partie inférieure de la grille et en la poussant vers le haut, celle-ci se détachant alors rapidement du boîtier. Après nettoyage de la grille 14, l'utilisateur la remet en place dans le boîtier simplement en la saisissant avec deux doigts et en l'orientant légèrement en direction de l'ouverture 12, la force d'attraction des aimants 25, respectivement 31 assurant l'auto centrage et la fixation de la grille, pratiquement à distance, et sans effort ou attention de la part de l'utilisateur, le cadre s'emboîtant dans les parois de l'ouverture 12 du boîtier 1. L'appareil est maintenant prêt pour une nouvelle utilisation.In operation, the user starts the device, he carries out the drying of the hair, then he stops the device. After several successive hair drying operations, the user detaches the

Les protubérances en V 35 comportent deux flancs 36 ayant une assez faible inclinaison, l'angle à la base du flanc étant de préférence compris entre 7° et 15°. Les flancs 38 des encoches en V 37 correspondantes ont une même inclinaison. En fonctionnement, les protubérances en V 35 de la grille 14 s'emboîtent dans les encoches en V 37 de l'ouverture 12 du boîtier lors de la mise en place de la grille, les aimants 31 assurant le maintien de cette dernière sur le boîtier. Lorsque l'on veut retirer la grille 14, on fait tourner le cadre 21 autour de l'axe longitudinal du boîtier, dans un sens ou dans l'autre, les flancs 36 ayant alors un rôle de came qui vient écarter les aimants 31 du boîtier de ceux du cadre 21 facilitant par la suite l'extraction de la grille.The

D'autres variantes et modes de réalisation de l'invention peuvent être envisagés sans sortir du cadre de ces revendications.Other variants and embodiments of the invention may be envisaged without departing from the scope of these claims.
Ainsi, la grille de l'invention peut équiper tout autre appareil soufflant de mise en forme des cheveux, tel que par exemple une brosse soufflante.Thus, the grid of the invention can equip any other blowing device shaping the hair, such as for example a blower brush.
On pourrait par ailleurs utiliser tout autre type de tissu filtrant ou maillage à partir de fibres textiles, de cellulose ou en matière plastique, tenu par un cadre rigide pour former ainsi une grille démontable. Le cadre rigide peut alors être réalisé en une matière métallique magnétisable lorsque amené en contact avec les aimants du boîtier ou en une autre matière non magnétisable, par exemple une matière plastique, mais dans ce cas le cadre doit être muni d'aimants sur sa périphérie interne, comme précédemment décrit.One could also use any other type of filter cloth or mesh from textile fibers, cellulose or plastic, held by a rigid frame to form a removable grid. The rigid frame can then be made of a magnetizable metal material when brought into contact with the magnets of the housing or other non-magnetizable material, for example a plastic material, but in this case the frame must be provided with magnets on its periphery internal, as previously described.
Dans une variante, on peut envisager un montage pivotant d'au moins un des aimants autour d'un axe perpendiculaire à celui de son champ magnétique et un moyen mécanique externe pour l'actionner en pivotement. En actionnant ce moyen externe, l'aimant pivote et écarte l'aimant en vis-à-vis de la grille facilitant ainsi son extraction.In a variant, it is possible to envisage a pivotal mounting of at least one of the magnets around an axis perpendicular to that of its magnetic field and external mechanical means for actuating it in pivoting. By actuating this external means, the magnet pivots and moves the magnet away from the grid, thus facilitating its extraction.
