Description

AP PARE I L DE N ETTOYAG E A F LUX D'AI R  AP I N ETTOYAG E A F LUX D'AI R
La présente invention concerne de manière générale un appareil de nettoyage tel qu'un aspirateur à main, et en particulier un aspirateur à main sans sac, autrement appelé aspirateur à main cyclonique. The present invention generally relates to a cleaning apparatus such as a hand-held vacuum cleaner, and in particular a bagless hand-held vacuum cleaner, otherwise known as a cyclonic hand-held vacuum cleaner.
Il est connu dans l'art antérieur des aspirateurs à main cycloniques, tel que celui divulgué par le document US8607407 avec une chambre cyclonique et des moyens de filtration (autrement dit un filtre) en sortie de chambre cyclonique. Un tel filtre en sortie de chambre cyclonique est agencé pour filtrer les particules de faible masse ou de petite taille qui ne seraient pas restées dans la chambre cyclonique. Un tel filtre est typiquement un filtre à micro particules ou une mousse. Une utilisation prolongée sans nettoyer ce filtre provoque une perte de performance significative. Dans le document US8607407, l'utilisateur doit effectuer une opération spécifique de démontage du filtre pour le nettoyer, ce qui complique le nettoyage, et de nombreux utilisateurs oublient même de nettoyer ce filtre. Un but de la présente invention est de répondre aux inconvénients de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un appareil de nettoyage à flux d'air, tel qu'un aspirateur à main, du type cyclonique (c'est-à-dire sans sac), mais dont le nettoyage des moyens de filtration est facilité pour l'utilisateur. Pour cela un premier aspect de l'invention concerne un appareil de nettoyage à flux d'air, tel qu'un aspirateur à main, comprenant : It is known in the prior art cyclonic hand vacuums, such as that disclosed in US8607407 with a cyclonic chamber and filter means (ie a filter) output cyclonic chamber. Such a cyclonic chamber outlet filter is arranged to filter the particles of low mass or small size that would not have remained in the cyclonic chamber. Such a filter is typically a micro particle filter or a foam. Prolonged use without cleaning this filter causes a significant loss of performance. In US8607407, the user must perform a specific operation of disassembly of the filter to clean it, which complicates the cleaning, and many users even forget to clean this filter. An object of the present invention is to meet the drawbacks of the prior art mentioned above and in particular, first of all, to propose an air-flow cleaning apparatus, such as a hand-held vacuum cleaner, the cyclonic type (that is to say without bag), but the cleaning of the filtration means is facilitated for the user. For this purpose, a first aspect of the invention relates to an air-flow cleaning apparatus, such as a hand-held vacuum cleaner, comprising:
- une chambre cyclonique agencée pour recevoir des impuretés,  a cyclonic chamber arranged to receive impurities,
- une trappe de vidage de la chambre cyclonique,  - a dump hatch of the cyclonic chamber,
- des moyens de filtration d'un flux d'air sortant de la chambre cyclonique, agencés dans la chambre cyclonique,  means for filtering an air flow leaving the cyclonic chamber, arranged in the cyclonic chamber,
- des moyens de commande agencés pour ouvrir manuellement la trappe de vidage, control means arranged to manually open the hatch of dump,
caractérisé en ce que les moyens de commande sont agencés pour provoquer une extraction des moyens de filtration hors de la chambre cyclonique, au cours d'une commande d'ouverture de la trappe. Pour vider la chambre cyclonique, l'utilisateur agit manuellement sur les moyens de commande pour ouvrir la trappe de vidage, et lors de cette action, les moyens de commande opèrent une extraction des moyens de filtration hors de la chambre cyclonique (simultanément ou séquentiellement à l'ouverture de la trappe de vidage). En conséquence, les moyens de filtration sont automatiquement éjectés hors de la chambre cyclonique lors de chaque vidage de la chambre cyclonique. Aucune opération spécifique n'est à accomplir par l'utilisateur, ce qui fait que ce dernier peut aisément contrôler les moyens de filtration et nettoyer ce filtre. La chambre cyclonique de l'appareil selon la présente invention est agencée pour séparer les impuretés du flux d'air et ensuite les collecter, avant d'être vidée. Le flux d'air/poussières entre à grande vitesse dans la chambre cyclonique. Cette dernière comprend une entrée tangentielle du canal d'entrée et la forme cylindrique assurent une trajectoire circulaire au flux. Par centrifugation, la majeure partie de la poussière est plaquée contre la paroi interne de la chambre cyclonique puis finit sa course dans le fond du bol, dans la zone réservoir. characterized in that the control means are arranged to cause an extraction of the filtering means out of the cyclonic chamber, during an opening command of the hatch. To empty the cyclone chamber, the user manually acts on the control means to open the emptying hatch, and during this action, the control means operate an extraction of the filtration means out of the cyclonic chamber (simultaneously or sequentially to the opening of the dump hatch). As a result, the filtration means are automatically ejected from the cyclonic chamber during each emptying of the cyclonic chamber. No specific operation is to be performed by the user, so that the user can easily control the filtration means and clean the filter. The cyclonic chamber of the apparatus according to the present invention is arranged to separate the impurities from the air flow and then collect them, before being emptied. The air / dust flow enters at high speed into the cyclonic chamber. The latter comprises a tangential inlet of the inlet channel and the cylindrical shape provide a circular path to the flow. By centrifugation, most of the dust is pressed against the inner wall of the cyclonic chamber and then ends up in the bottom of the bowl, in the reservoir zone.
Avantageusement, la chambre cyclonique comprend un corps de forme allongée, agencé entre une première extrémité et une deuxième extrémité, les moyens de filtration et les moyens de commande sont agencés à la première extrémité, et la trappe de vidage est agencée à la deuxième extrémité. En d'autres termes, la chambre cyclonique est agencée entre les moyens de filtration et la trappe de vidage, et les moyens de commande sont déportés de la trappe de vidage, pour être à proximité immédiate des moyens de filtration. Avantageusement, l'appareil comprend des moyens élastiques d'éjection pour provoquer une éjection automatique des moyens de filtration lorsque les moyens de commande sont actionnés pour commander l'ouverture de la trappe de vidage. Avantageusement, les moyens de commande comprennent : Advantageously, the cyclonic chamber comprises an elongated body, arranged between a first end and a second end, the filtering means and the control means are arranged at the first end, and the emptying hatch is arranged at the second end. In other words, the cyclonic chamber is arranged between the filtering means and the emptying hatch, and the control means are remote from the emptying hatch, to be in the immediate vicinity of the filtration means. Advantageously, the apparatus comprises elastic ejection means for causing an automatic ejection of the filtering means when the control means are actuated to control the opening of the emptying hatch. Advantageously, the control means comprise:
- une poignée de commande agencée pour être actionnée par un utilisateur entre une position de verrouillage et une position de vidage, et comprenant au moins une came,  a control handle arranged to be actuated by a user between a locking position and a emptying position, and comprising at least one cam,
- des moyens de transmission agencés entre la came et un verrou de la trappe de vidage,  transmission means arranged between the cam and a lock of the emptying hatch,
ladite au moins une came étant agencée pour s'engager, lors d'un mouvement de la poignée de commande depuis la position de verrouillage vers la position de vidage, avec une première piste de came solidaire des moyens de transmission pour commander l'ouverture de la trappe, et avec une deuxième piste de came pour provoquer l'extraction des moyens de filtration, de manière séquentielle ou simultanée. Dans la position de verrouillage, la trappe de vidage ainsi que les moyens de filtration sont montés sur la chambre cyclonique pour permettre une utilisation de l'appareil de nettoyage, et dans la position de vidage, la trappe de vidage est ouverte, et les moyens de filtration sont hors de la chambre cyclonique. C'est la came solidaire de la poignée de commande qui provoque les actions mécaniques sur les moyens de transmission pour ouvrir la trappe de vidage, et sur la deuxième piste de came pour éjecter les moyens de filtration. La deuxième piste de came peut être solidaire de la chambre cyclonique ou d'un corps principal de l'appareil de nettoyage. said at least one cam being arranged to engage, upon movement of the control handle from the lock position to the emptying position, with a first integral cam track of the transmission means for controlling the opening of the hatch, and with a second cam track to cause the extraction of the filtration means, sequentially or simultaneously. In the locking position, the emptying hatch and the filtration means are mounted on the cyclonic chamber to allow use of the cleaning apparatus, and in the emptying position, the emptying hatch is open, and the means filtration are out of the cyclonic chamber. It is the integral cam of the control handle which causes the mechanical actions on the transmission means to open the emptying flap, and on the second cam track to eject the filtration means. The second cam track may be integral with the cyclonic chamber or a main body of the cleaning apparatus.
Avantageusement, la première piste de came et la deuxième piste de came sont respectivement une première portion et une deuxième portion d'une piste de came unique. Lors de la coopération avec la première portion, il n'y a pas déplacement des moyens de filtration. Avantageusement, la poignée de commande est solidaire des moyens de filtration. Cela permet de manipuler les moyens de filtration sans les toucher, au moyen de la poignée de commande, et l'hygiène est améliorée. Advantageously, the first cam track and the second cam track are respectively a first portion and a second portion of a single cam track. When cooperating with the first portion, there is no displacement of the filtration means. Advantageously, the control handle is secured to the filtering means. This makes it possible to manipulate the filtration means without touching them, by means of the control handle, and the hygiene is improved.
Avantageusement, la poignée de commande est agencée en partie supérieure de l'appareil de nettoyage. Cet agencement permet une utilisation aisée pour l'utilisateur si l'appareil présente une autre poignée opposée. Advantageously, the control handle is arranged in the upper part of the cleaning device. This arrangement allows easy use for the user if the apparatus has another opposite handle.
Avantageusement, la came est agencée pour s'engager avec une piste de came statique lorsque la poignée de commande est dans la position de verrouillage, pour bloquer la poignée de commande en position de verrouillage. C'est la même came qui assure les trois fonctions suivantes : commander la trappe de vidage, éjecter les moyens de filtration et bloquer la poignée de commande en position de verrouillage. Advantageously, the cam is arranged to engage with a static cam track when the control handle is in the locking position, to lock the control handle in the locking position. It is the same cam that provides the following three functions: control the emptying hatch, eject the filtering means and lock the control handle in the locked position.
Avantageusement, les moyens de commande comprennent un verrou agencé pour maintenir la trappe de vidage dans une position fermée lors de l'utilisation de l'appareil de nettoyage. Advantageously, the control means comprise a latch arranged to hold the emptying flap in a closed position when using the cleaning apparatus.
Avantageusement, le verrou est agencé pour maintenir la trappe de vidage fermée sans contact avec cette dernière. La fabrication des pièces est améliorée, il y a moins d'interfaces mécaniques à prévoir. Advantageously, the lock is arranged to keep the dump hatch closed without contact with the latter. Parts manufacturing is improved, there are fewer mechanical interfaces to predict.
Avantageusement, le verrou est magnétique. Avantageusement, le verrou comprend une pince. Advantageously, the lock is magnetic. Advantageously, the lock comprises a clamp.
Avantageusement, la pince présente deux becs, et l'appareil comprend un coin agencé entre une jonction des deux becs, pour provoquer un écartement des deux becs lors d'une translation des deux becs commandée par les moyens de commande. Les deux becs présentent un espace entre eux, et la fermeture de la pince est assurée par les propriétés élastiques des becs lorsqu'ils coulissent sur le coin dans l'autre sens que pour l'ouverture. Advantageously, the clamp has two spouts, and the apparatus comprises a wedge arranged between a junction of the two spouts, to cause a spacing of the two spouts during a translation of the two spouts controlled by the control means. The two nozzles have a space between them, and the closing of the clip is ensured by the elastic properties of the nozzles when sliding on the corner in the other direction than for the opening.
Avantageusement, l'un de la trappe de vidage et du verrou comprend au moins un aimant et l'autre de la trappe de vidage et du verrou comprend au moins un matériau magnétique, agencés pour coopérer ensemble afin de maintenir la trappe de vidage en position fermée, sans contact entre le verrou et la trappe de vidage. Advantageously, one of the emptying flap and the lock comprises at least one magnet and the other of the emptying flap and the lock comprises at least one magnetic material, arranged to cooperate together in order to maintain the emptying hatch in the closed position, without contact between the lock and the emptying hatch.
Avantageusement, l'aimant est monté sur une roue dentée des moyens de commande. On peut envisager de commander la roue dentée par une crémaillère, par un câble qui actionne en rotation une « cage aimant cylindrique », l'attache du câble étant excentrée du pivot. On peut également envisager de placer l'aimant à l'extrémité d'une bande souple, celle-ci étant guidée par un chemin dont la forme permette un retournement de 180° de l'aimant. Advantageously, the magnet is mounted on a gear wheel of the control means. It is conceivable to control the toothed wheel by a rack, by a cable which actuates in rotation a "cylindrical magnet cage", the cable attachment being eccentric from the pivot. It is also possible to consider placing the magnet at the end of a flexible strip, the latter being guided by a path whose shape allows a 180 ° reversal of the magnet.
Avantageusement, un premier aimant est monté sur la roue dentée selon une première orientation polaire vis-à-vis du rayon de la roue dentée, et la roue dentée comprend un deuxième aimant monté selon une deuxième orientation polaire opposée à la première orientation polaire, et la trappe de vidage comprend un troisième aimant, agencé pour être attiré par le premier aimant, et repoussé par le deuxième aimant, lorsque la trappe de vidage est en position fermée. Le troisième aimant est attiré par le premier aimant lorsque la trappe de vidage est fermée. Lors d'une commande d'ouverture, les moyens de commande provoquent une rotation de la roue dentée pour présenter le deuxième aimant en regard du troisième aimant, ce qui repousse ce dernier et force l'ouverture de la trappe de vidage. Advantageously, a first magnet is mounted on the toothed wheel in a first polar orientation with respect to the radius of the toothed wheel, and the toothed wheel comprises a second magnet mounted in a second polar orientation opposite to the first polar orientation, and the emptying hatch comprises a third magnet, arranged to be attracted by the first magnet, and pushed back by the second magnet, when the emptying hatch is in the closed position. The third magnet is attracted to the first magnet when the dump door is closed. During an opening command, the control means cause a rotation of the toothed wheel to present the second magnet facing the third magnet, which pushes the latter and forces the opening of the emptying hatch.
Alternativement, un seul aimant est monté sur la roue dentée et présente deux pôles agencés pour qu'un premier pôle attire le troisième aimant lorsque la trappe de vidage est en position fermée et la poignée de commande en position de verrouillage, et pour qu'un deuxième pôle repousse le troisième aimant lorsque la trappe de vidage est en position fermée et la poignée de commande en position de vidage. Alternatively, a single magnet is mounted on the toothed wheel and has two poles arranged so that a first pole attracts the third magnet when the emptying hatch is in the closed position and the control handle in the locking position, and for a second pole pushes the third magnet when the emptying hatch is in the closed position and the control handle in the emptying position.
Avantageusement, l'appareil de nettoyage présente un corps principal, la chambre cyclonique est séparée du corps principal et/ou les moyens de commande sont solidaires de la chambre cyclonique. La conception du corps principal de l'appareil (qui supporte le moto ventilateur et une batterie) est simplifiée, puisque toute la mécanique des moyens de commande est embarquée sur la chambre cyclonique. Advantageously, the cleaning apparatus has a main body, the cyclonic chamber is separated from the main body and / or the control means are integral with the cyclonic chamber. Body design main device (which supports the motorcycle fan and a battery) is simplified, since all the mechanics of the control means is embedded on the cyclonic chamber.
Avantageusement, l'appareil de nettoyage comprend un corps principal et des moyens de verrouillage de la chambre cyclonique sur le corps principal de l'appareil, et les moyens de commande sont agencés pour commander, au cours de la commande d'ouverture de la trappe de vidage, les moyens de verrouillage pour déverrouiller la chambre cyclonique du corps principal. La chambre cyclonique est rendue amovible par rapport au corps principal, et son déverrouillage permet de la retirer pour la nettoyer par exemple. Advantageously, the cleaning apparatus comprises a main body and locking means of the cyclonic chamber on the main body of the apparatus, and the control means are arranged to control, during the opening control of the hatch. emptying means, the locking means for unlocking the cyclonic chamber of the main body. The cyclonic chamber is made removable relative to the main body, and its unlocking allows it to be removed for cleaning, for example.

La figure 1 représente un aspirateur à main comprenant une chambre cyclonique 10 (plus précisément une chambre mono-cyclonique) accouplée à un corps principal 50, et présentant une bouche d'aspiration 1 1 . Le corps principal 50 présente une poignée de préhension et contient typiquement un moto ventilateur, une batterie agencée pour alimenter le moto ventilateur afin de créer un flux d'aspiration qui permet d'aspirer des impuretés par la bouche d'aspiration 1 1 , les impuretés étant ensuite séparées par centrifugation dans la chambre cyclonique 10 et stockées dans celle-ci. FIG. 1 represents a hand-held vacuum cleaner comprising a cyclonic chamber 10 (more precisely a mono-cyclonic chamber) coupled to a main body 50, and having a suction mouth 1 1. The main body 50 has a handle and typically contains a motorcycle fan, a battery arranged to power the motorcycle fan to create a suction flow that can suck impurities through the suction mouth 1 1, impurities being then centrifugally separated in the cyclonic chamber 10 and stored therein.
Dans ce type d'appareil, le flux d'air passe ensuite dans des moyens de filtration 30 qui sont agencés en sortie aval de la chambre cyclonique 10, pour éliminer toutes les impuretés trop légères ou trop fines pour être séparées par centrifugation et qui seraient toujours entraînées par le flux d'air. In this type of apparatus, the air flow then passes into filtration means 30 which are arranged at the downstream outlet of the cyclonic chamber 10, to eliminate any impurities too light or too fine to be separated by centrifugation and which would be always driven by the airflow.
Une trappe de vidage 20 est prévue à une extrémité de la chambre cyclonique 10, les moyens de filtration 30 étant agencés à l'autre extrémité de la chambre cyclonique 10. Pour ouvrir cette trappe de vidage 20, l'aspirateur à main est muni de moyens de commande comprenant notamment une poignée de commande 41 et permettant une ouverture manuelle. Pour être aisément manipulable, la poignée de commande 41 est déportée de la trappe de vidage 20, et agencée sur les moyens de filtration 30. Plus particulièrement, la poignée de commande 41 est solidaire des moyens de filtration 30, elle est montée en liaison pivot par rapport à ces derniers. A dump hatch 20 is provided at one end of the cyclonic chamber 10, the filtration means 30 being arranged at the other end of the cyclonic chamber 10. To open the emptying hatch 20, the hand-held vacuum cleaner is equipped with control means including a control handle 41 and allowing manual opening. To be easily manipulated, the control handle 41 is offset from the emptying flap 20, and arranged on the filtering means 30. More particularly, the control handle 41 is integral with the filtering means 30, it is mounted in pivot connection compared to these.
Les moyens de filtration 30 peuvent être un module qui comprend un micro filtre, ou une mousse qu'il importe de nettoyer régulièrement, sans quoi un colmatage apparaît, et les performances d'aspiration sont nettement dégradées. A cet effet, l'invention propose d'extraire automatiquement les moyens de filtration 30 à chaque fois que la chambre cyclonique 10 est vidée des impuretés qui ont été stockées au cours de l'utilisation de l'aspirateur à main. The filtration means 30 may be a module which comprises a micro filter, or a foam which it is important to clean regularly, otherwise clogging occurs, and the suction performance is significantly degraded. For this purpose, the invention proposes to automatically extract the filtration means 30 each time the cyclonic chamber 10 is emptied of impurities that have been stored during the use of the hand-held vacuum cleaner.
La figure 2 représente justement une opération de vidage de la chambre cyclonique 10. L'utilisateur actionne la poignée de commande 41 pour la faire pivoter approximativement d'un quart de tour. Au cours de cette rotation, la poignée de commande 41 qui comprend deux cames 45 (une seule est visible ici, et également sur la figure 4) force l'ouverture de la trappe de vidage 20, mais également pousse vers le haut les moyens de filtration 30, comme le représente la flèche. FIG. 2 represents a emptying operation of the cyclone chamber 10. The user actuates the control handle 41 to rotate it about a quarter of a turn. During this rotation, the control handle 41 which includes two cams 45 (only one is visible here, and also in Figure 4) forces the opening of the emptying flap 20, but also pushes up the means of filtration 30, as shown by the arrow.
L'ouverture de la trappe de vidage 20 est effectuée par une action des cames 45 sur des moyens de transmission, et le mouvement des moyens de filtration 30 est provoqué par l'action des cames 45 sur une partie statique de l'aspirateur à main (la chambre cyclonique 10 ou le corps principal 50). L'ouverture de la trappe de vidage 20 et le mouvement d'extraction des moyens de filtration 30 peuvent être simultanés ou séquentiels, mais ils sont tous deux commandés par la rotation de la poignée de commande 41 . The opening of the emptying flap 20 is effected by an action of the cams 45 on transmission means, and the movement of the filtration means 30 is caused by the action of the cams 45 on a static part of the hand-held vacuum cleaner (The cyclonic chamber 10 or the main body 50). The opening of the emptying flap 20 and the extraction movement of the filtration means 30 may be simultaneous or sequential, but they are both controlled by the rotation of the control handle 41.
Les moyens de filtration 30 sont donc éjectés hors de la chambre cyclonique 10, et comme la poignée de commande 41 est solidaire des moyens de filtration 30, l'utilisateur peut les examiner sans les toucher, ce qui améliore l'hygiène et l'ergonomie de l'opération. Si les moyens de filtration 30 sont colmatés, l'utilisateur peut alors facilement les nettoyer au dessus de la poubelle dans laquelle ont été précédemment versées les impuretés contenues dans la chambre cyclonique 10 lors de l'ouverture de la trappe de vidage 20. The filtration means 30 are thus ejected from the cyclonic chamber 10, and since the control handle 41 is integral with the filtration means 30, the user can examine them without touching them, which improves hygiene and ergonomics. of the operation. If the filtration means 30 are clogged, the user can then easily clean them above the trash in which were previously poured the impurities in the cyclonic chamber 10 when opening the dump flap 20.
La figure 3 représente une première mise en œuvre des moyens de commande. En effet, afin de commander la trappe de vidage 20 de manière déportée, les moyens de commande de l'aspirateur à main comprennent des moyens de transmission qui dans une première mise en œuvre comprennent une tige de renvoi 43 (agencée derrière une barre 44 indépendante). Cette tige de renvoi 43 est actionnée par les cames 45 (non visibles sur cette figure) afin de commander l'ouverture de la trappe de vidage 20, par l'intermédiaire d'une pince fendue comprenant deux becs 42, entre lesquels un coin 43a est agencé solidaire de la tige de renvoi 43. Lors du mouvement de la poignée de commande 41 pour ouvrir la trappe de vidage 20, la tige de renvoi 43 coulisse vers le haut et tire le coin 43a qui force les becs 42 à s'écarter l'un de l'autre, ce qui libère le pêne 21 de la trappe de vidage 20, qui peut alors s'ouvrir. Dès que la tige de renvoi 43 rebaisse sous l'action de la came 45, et/ou en raison de l'effort élastique des becs 42, ces derniers se referment. Figure 3 shows a first implementation of the control means. Indeed, in order to control the emptying flap 20 remotely, the control means of the hand-held vacuum cleaner comprise transmission means which in a first implementation comprise a return rod 43 (arranged behind an independent bar 44). ). This return rod 43 is actuated by the cams 45 (not visible in this figure) in order to control the opening of the emptying flap 20, via a split pliers comprising two spouts 42, between which a wedge 43a is arranged integral with the return rod 43. During the movement of the control handle 41 to open the emptying flap 20, the return rod 43 slides upwards and pulls the wedge 43a which forces the spouts 42 to move away from each other, which releases the bolt 21 of the emptying hatch 20, which can then open. As soon as the return rod 43 rebases under the action of the cam 45, and / or because of the elastic force of the nozzles 42, the latter close again.
Une fois la chambre cyclonique 10 vidée, l'utilisateur peut la refermer et la trappe de vidage 20 sera automatiquement verrouillée car le pêne 21 sera pincé et verrouillé par les becs 42 revenus en position de verrouillage. La barre 44 permet de proposer une fonction supplémentaire de démontage de la chambre cyclonique 10. En effet, il peut être intéressant de détacher la chambre cyclonique 10 du corps principal 50 de l'aspirateur à main, pour la nettoyer. A cet effet, la barre 44 comprend deux demi-lunes 44a qui appuient sur des verrous 31 . Lorsque la poignée de commande 41 est actionnée pour ouvrir la trappe de vidage 20 comme expliqué ci-dessus, les moyens de filtration 30 sont également extraits de la chambre cyclonique 10 et montent vers le haut. A ce moment là, la barre 44 se trouve libérée, et peut monter vers le haut, ce qui laisse les verrous 31 se rapprocher entre eux, c'est-à-dire se rétracter. A ce moment là, seules les extrémités biseautées des verrous 31 sont en prises avec le corps principal 50, ce qui permet de maintenir la chambre cyclonique 10 sur ce dernier, mais l'utilisateur peut toutefois aisément détacher la chambre cyclonique 10 du corps principal 50. Once the cyclonic chamber 10 emptied, the user can close it and the emptying flap 20 will be automatically locked because the bolt 21 will be pinched and locked by the latches 42 returned to the locked position. The bar 44 can provide an additional function of disassembly of the cyclonic chamber 10. Indeed, it may be advantageous to detach the cyclonic chamber 10 of the main body 50 of the hand vacuum, for cleaning. For this purpose, the bar 44 comprises two half-moons 44a which press on locks 31. When the control handle 41 is actuated to open the emptying flap 20 as explained above, the filtration means 30 are also extracted from the cyclonic chamber 10 and rise upwards. At this moment, the bar 44 is released, and can rise upwards, which allows the locks 31 to approach each other, that is to retract. At this moment, only the beveled ends of the latches 31 are engaged with the main body 50, which keeps the cyclonic chamber 10 on the latter, but the user can however easily detach the cyclonic chamber 10 of the main body 50 .
Lors du remontage, l'utilisateur positionne la chambre cyclonique 10 sur le corps principal 50 et monte ensuite les moyens de filtration 30 sur l'aspirateur à main. Lors du mouvement de verrouillage des moyens de filtration 30, les cames 45 forcent les moyens de filtration 30 à descendre, ce qui pousse en même temps la barre 44 vers le bas et force la sortie des verrous 31 par l'intermédiaire des demi-lunes 44a. La chambre cyclonique 10 est alors à nouveau verrouillée sur le corps principal 50. Il est avantageux de prévoir de débrayer la tige de renvoi 43 de la came 45 et de la poignée de commande 41 et des moyens de filtration 30, pour permettre à l'utilisateur de pouvoir verrouiller la trappe de vidage 20, que les moyens de filtration 30 soient remontés ou non dans la chambre cyclonique 10, cette dernière étant remontée ou non sur le corps principal 50. During reassembly, the user positions the cyclonic chamber 10 on the main body 50 and then rises the filtering means 30 on the hand-held vacuum cleaner. During the locking movement of the filtration means 30, the cams 45 force the filtration means 30 to descend, which at the same time pushes the bar 44 downwards and forces the latches 31 to exit via the half-moons 44a. The cyclonic chamber 10 is then again locked on the main body 50. It is advantageous to provide for disengaging the return rod 43 of the cam 45 and the control handle 41 and the filtering means 30, to allow the user to be able to lock the emptying hatch 20, that the filtration means 30 are raised or not in the cyclonic chamber 10, the latter being raised or not on the main body 50.
Il est à noter que les moyens de commande (et les moyens de transmission) sont tous embarqués sur la chambre cyclonique 10 afin de laisser le corps principal 50 de l'aspirateur à main libre de ces organes. La conception est facilitée. La figure 4 représente une deuxième mise en œuvre des moyens de commande d'ouverture de la trappe de vidage 20. Cette dernière ne comprend plus de pêne 21 , mais le maintien en position fermée est assuré par des moyens magnétiques. En particulier, les moyens de commande comprennent un premier aimant 49a et un deuxième aimant 49b, afin de coopérer avec un troisième aimant 22 inséré dans la trappe de vidage 20. It should be noted that the control means (and the transmission means) are all mounted on the cyclonic chamber 10 in order to leave the main body 50 of the vacuum hand free of these organs. The design is facilitated. FIG. 4 shows a second implementation of the opening control means of the emptying flap 20. The latter no longer includes a bolt 21, but the holding in the closed position is provided by magnetic means. In particular, the control means comprise a first magnet 49a and a second magnet 49b, in order to cooperate with a third magnet 22 inserted into the emptying flap 20.
Lors du mouvement de déverrouillage de la poignée de commande 41 vers le haut, la came 45 pousse les moyens de filtration 30 vers le haut pour les éjecter hors de la chambre cyclonique 10, en s'appuyant sur une partie statique de l'aspirateur à main, représentée sous une forme hachurée. Simultanément, les moyens de filtration 30 tirent sur un tige de renvoiDuring the unlocking movement of the control handle 41 upwards, the cam 45 pushes the filtration means 30 upwards to eject them out of the cyclonic chamber 10, relying on a static part of the vacuum cleaner hand, represented in hatched form. At the same time, the filtration means 30 pull on a return rod
46 (de forme différente de la tige de renvoi 43 de la première mise en œuvre), qui tire à son tour sur une crémaillère 47 afin d'entraîner en rotation un arbre 48 sur lequel sont montés le premier aimant 49a et le deuxième aimant 49b. Dans la position telle que représentée, le premier aimant 49a est orienté de sorte à ce que son flux magnétique attire le troisième aimant 22. Lorsque la poignée de commande 41 est actionnée, c'est le deuxième aimant 49b qui arrive alors en regard du troisième aimant 22, et son orientation polaire est inversée par rapport au premier aimant 49a, de sorte que le deuxième aimant 49b repousse le troisième aimant 22, pour provoquer l'ouverture de la trappe de vidage 20. En alternative, on peut envisager de n'utiliser qu'un seul aimant embarqué sur l'arbre 48. 46 (of different shape of the return rod 43 of the first implementation), which in turn pulls on a rack 47 to rotate a shaft 48 on which are mounted the first magnet 49a and the second magnet 49b . In the position as shown, the first magnet 49a is oriented so that its magnetic flux attracts the third magnet 22. When the control handle 41 is actuated, it is the second magnet 49b which then arrives opposite the third magnet 22, and its polar orientation is inverted relative to the first magnet 49a, so that the second magnet 49b pushes the third magnet 22, to cause the opening of the emptying flap 20. Alternatively, it is conceivable to use only one embedded magnet on the shaft 48.
En fin de mouvement vertical des moyens de filtration 30, la tige de renvoi 46 peut fléchir afin de se dégager des moyens de filtration 30, pour permettre une désolidarisation complète de ces derniers afin que l'utilisateur les nettoie si nécessaire. At the end of the vertical movement of the filtration means 30, the return rod 46 can flex in order to disengage from the filtration means 30, to allow complete separation of the latter so that the user cleans them if necessary.
