Description

Domaine techniqueTechnical area

La présente invention concerne le domaine des appareils de nettoyage et, plus particulièrement, un aspirateur à main sans sac, autrement appelé aspirateur à main cyclonique.The present invention relates to the field of cleaning devices and, more particularly, to a bagless hand-held vacuum cleaner, otherwise known as a cyclonic hand-held vacuum cleaner.

Un tel aspirateur a pour vocation d'être compact et porté avec une main pour aspirer des surfaces basses, par exemple un plan de travail ou des marches d'escalier, ou des surfaces rehaussées, par exemple un plafond ou un mur voire un mobilier disposé en hauteur.Such a vacuum cleaner is intended to be compact and carried with one hand to vacuum low surfaces, for example a worktop or staircase steps, or raised surfaces, for example a ceiling or a wall or even furniture arranged in height.

Etat de la techniqueState of the art

Les aspirateurs à main sans sac sont connus de l'homme du métier. Un tel aspirateur comprend un corps qui est muni à l'arrière d'une poignée de préhension et qui intègre des moyens d'aspiration. L'aspirateur comprend également un tube d'aspiration par l'extrémité avant duquel sont aspirées les impuretés et une chambre de filtration agencée entre le tube d'aspiration et les moyens d'aspiration sur le corps pour recevoir et stocker provisoirement les impuretés aspirées. La chambre de filtration comprend un bol qui communique avec le tube d'aspiration et un élément filtrant qui est logé dans le bol et qui communique avec les moyens d'aspiration.Bagless hand-held vacuum cleaners are known to those skilled in the art. Such a vacuum cleaner comprises a body which is provided at the rear with a gripping handle and which incorporates suction means. The vacuum cleaner also comprises a suction tube through the front end of which the impurities are sucked and a filtration chamber arranged between the suction tube and the suction means on the body to receive and temporarily store the sucked impurities. The filtration chamber comprises a bowl which communicates with the suction tube and a filter element which is housed in the bowl and which communicates with the suction means.

Lors de l'activation des moyens d'aspiration, le flux d'air génère une dépression permettant d'aspirer les impuretés par l'extrémité avant du tube d'aspiration ; le flux d'air chargé d'impuretés circule dans ledit tube puis pénètre dans le bol où les impuretés restent emprisonnées en grande partie grâce à une force centrifuge générée dans ce bol, tandis que l'élément filtrant disposé en aval (en tenant compte du sens de circulation du flux d'air) permet de retenir les fines particules d'impuretés, le flux d'air filtré poursuivant ensuite son circuit dans le corps sous l'action desdits moyens d'aspiration, pour être finalement rejeté dudit corps, par exemple à l'arrière de celui-ci.When the suction means are activated, the air flow generates a vacuum making it possible to suck up the impurities through the front end of the suction tube; the flow of air laden with impurities circulates in said tube then enters the bowl where the impurities remain trapped largely thanks to a centrifugal force generated in this bowl, while the filter element arranged downstream (taking into account the direction of circulation of the air flow) makes it possible to retain the fine particles of impurities, the filtered air flow then continuing its circuit in the body under the action of said suction means, to be finally rejected from said body, by example on the back of it.

On citera notamment les demandes de brevet FR3030215A1 , WO2014080179A1 et WO2014080180A1 divulguant de telles caractéristiques.These include patent applications FR3030215A1 , WO2014080179A1 and WO2014080180A1 disclosing such characteristics.

Dans la demande de brevet FR 3030215 A1 , le tube d'aspiration est intégré au bol, l'ensemble étant assemblé avec le corps. Le bol comprend en partie inférieure une trappe dont l'ouverture s'effectue au moyen d'une commande déportée, l'ouverture de la trappe permettant de vider le bol. Cette commande déportée est configurée pour concomitamment extraire l'élément filtrant par le dessus du bol, afin de garantir un nettoyage régulier de l'élément filtrant à chaque vidange du bol. L'ensemble tube, bol et élément filtrant est amovible du corps pour permettre un nettoyage complet du bol, l'extraction de l'ensemble étant réalisée grâce à la commande déportée.In the patent application FR 3030 215 A1 , the suction tube is integrated into the bowl, the assembly being assembled with the body. The bowl comprises in the lower part a hatch whose opening is effected by means of a remote control, the opening of the hatch making it possible to empty the bowl. This remote control is configured to concomitantly extract the filtering element from above the bowl, in order to guarantee regular cleaning of the filter element each time the bowl is emptied. The tube, bowl and filter element assembly is removable from the body to allow complete cleaning of the bowl, the assembly being extracted using the remote control.

Dans les demandes de brevet WO2014080179A1 et WO2014080180A1 , décrivant un aspirateur à main de conception similaire, le tube d'aspiration est intégré au bol, l'ensemble étant amovible du corps. Pour cela, des moyens d'assemblage sont mis en œuvre entre une face arrière du bol et une face avant du corps. L'arrière et l'avant sont définis respectivement en regard des positions de la poignée de préhension et du tube d'aspiration sur l'aspirateur. Le bol comprend en partie inférieure une trappe. Le corps comprend un organe de commande permettant de déverrouiller les moyens d'assemblage pour extraire le bol et permettre le nettoyage de l'élément filtrant. Cet organe de commande permet également l'ouverture de la trappe pour la vidange du bol.In patent applications WO2014080179A1 and WO2014080180A1 , describing a hand-held vacuum cleaner of similar design, the suction tube is integrated into the bowl, the assembly being removable from the body. For this, assembly means are implemented between a rear face of the bowl and a front face of the body. The rear and the front are defined respectively opposite the positions of the grip handle and the suction tube on the vacuum cleaner. The bowl has a hatch in the lower part. The body comprises a control member making it possible to unlock the assembly means for extracting the bowl and allowing the filtering element to be cleaned. This control member also allows the opening of the hatch for emptying the bowl.

Résumé de l'inventionSummary of the invention

La présente invention a pour premier objectif de faciliter la manipulation de l'aspirateur dans toutes les situations d'utilisation, c'est-à-dire aussi bien lorsqu'il s'agit d'aspirer des surfaces au sol que lorsqu'il s'agit d'aspirer des surfaces rehaussées.The first objective of the present invention is to facilitate the handling of the vacuum cleaner in all situations of use, that is to say both when it comes to vacuuming surfaces on the ground and when it is in use. 'acts of vacuuming raised surfaces.

Un autre objectif est que ces moyens d'assemblage du bol sur le corps assurent une fixation convenable entre ces deux éléments afin que le détachement du bol ne puisse pas se produire en cas de chocs sur celui-ci occasionnés durant la manipulation de l'aspirateur.Another objective is that these means of assembling the bowl on the body ensure a suitable fixing between these two elements so that the detachment of the bowl cannot occur in the event of impacts on the latter caused during handling of the vacuum cleaner. .

Un autre objectif est d'optimiser l'aspiration des impuretés en assurant une très bonne étanchéité lors de l'assemblage du bol sur le corps.Another objective is to optimize the suction of impurities by ensuring a very good seal during the assembly of the bowl on the body.

Un autre objectif est de faciliter la manipulation du bol durant sa vidange ou son nettoyage et celle de l'élément filtrant inséré dans le bol.Another objective is to facilitate the handling of the bowl during its emptying or cleaning and that of the filter element inserted in the bowl.

A cet effet, l'invention concerne un appareil de nettoyage de type aspirateur à main, nommé « aspirateur » dans la suite de la description.To this end, the invention relates to a cleaning appliance of the hand-held vacuum cleaner type, called “vacuum cleaner” in the remainder of the description.

Selon l'invention, l'aspirateur à main comprend un corps muni d'une première poignée de préhension agencée à l'arrière de l'aspirateur et de moyens d'aspiration, un tube d'aspiration agencé à l'avant de l'aspirateur et une chambre d'aspiration munie d'un bol communiquant avec le tube d'aspiration, et d'un élément filtrant inséré dans le bol et qui communique avec les moyens d'aspiration, caractérisé en ce que l'aspirateur comprend une deuxième poignée de préhension situé à l'avant de l'aspirateur, les axes longitudinaux des première et deuxième poignées étant sensiblement parallèles.According to the invention, the hand-held vacuum cleaner comprises a body provided with a first gripping handle arranged at the rear of the vacuum cleaner and with suction means, a suction tube arranged at the front of the vacuum cleaner. vacuum cleaner and a suction chamber provided with a bowl communicating with the suction tube, and a filter element inserted in the bowl and which communicates with the suction means, characterized in that the vacuum cleaner comprises a second gripping handle located at the front of the vacuum cleaner, the longitudinal axes of the first and second handles being substantially parallel.

Selon un autre mode de réalisation, la deuxième poignée de préhension est solidaire de la surface extérieure du bol.According to another embodiment, the second gripping handle is integral with the outer surface of the bowl.

Selon un autre mode de réalisation, la deuxième poignée de préhension est montée sur le tube d'aspiration. On peut toutefois prévoir que les deux extrémités de la deuxième poignée sont solidaires du bol.According to another embodiment, the second gripping handle is mounted on the suction tube. However, provision can be made for the two ends of the second handle to be integral with the bowl.

Toujours en vue d'améliorer l'ergonomie de l'aspirateur, la longueur et le diamètre des première et deuxième poignées sont sensiblement identiques. Ainsi, l'aspirateur peut être manipulé de façon identique par un utilisateur gaucher ou droitier sans que l'usage ne diffère d'un utilisateur à l'autre.Still with a view to improving the ergonomics of the vacuum cleaner, the length and diameter of the first and second handles are substantially identical. Thus, the vacuum cleaner can be handled identically by a left-handed or right-handed user without the use differing from one user to another.

Selon un autre mode de réalisation, un système de guidage et de maintien est agencé entre une face arrière du bol et une face avant du corps pour engager le bol sur le corps jusqu'à atteindre une position de formation de ladite chambre d'aspiration ou, inversement, pour dégager le bol du corps jusqu'à atteindre une position de séparation. Ledit système de guidage et de maintien est configuré pour accompagner le mouvement du bol sur le corps durant son engagement ou son dégagement. Par ailleurs, un système de verrouillage est agencé entre une partie supérieure avant du bol et une partie avant du corps pour verrouiller le bol sur le corps en position de formation de la chambre d'aspiration ou pour déverrouiller le bol du corps de sorte à le dégager.According to another embodiment, a guiding and holding system is arranged between a rear face of the bowl and a front face of the body to engage the bowl on the body until a position of formation of said suction chamber is reached or conversely, to release the bowl from the body until it reaches a separation position.

Description détailléedetailed description

Dans la suite de la description, l'aspirateur à main sans sac objet de l'invention sera dénommé aspirateur. En outre, les mêmes références seront utilisées pour désigner les mêmes caractéristiques selon les diverses variantes, sauf indication contraire.In the remainder of the description, the bagless hand vacuum cleaner which is the subject of the invention will be called a vacuum cleaner. In addition, the same references will be used to designate the same characteristics according to the various variants, unless otherwise indicated.

Tel qu'illustré notamment sur les figures 1 à 3, l'aspirateur 1 comprend un corps 2 qui comprend une partie arrière 2a et une partie avant 2b. La partie arrière 2a comprend une première poignée de préhension 4 que l'utilisateur peut saisir avec la main pour manipuler l'aspirateur 1. La première poignée de préhension 4 est disposée dans la partie inférieure 1a de l'aspirateur 1. De préférence, l'aspirateur 1 est alimenté électriquement au moyen d'une batterie rechargeable (non illustrée) disposée dans un socle 5 qui est assemblé avec le corps 2 sous la première poignée de préhension 4. L'aspirateur 1 comprend un tube 6 à l'extrémité avant 6a duquel sont aspirées des impuretés. Cette aspiration est assurée par un flux d'air qui génère une dépression à l'extrémité avant 6a du tube 6. La partie arrière 2a du corps comprend une zone 7 dans laquelle est logé un ventilateur (non illustré) alimenté par la batterie, qui permet de générer ledit flux d'air circulant de l'avant vers l'arrière de l'aspirateur 1. Le ventilateur est disposé dans la partie supérieure 1b de l'aspirateur 1, tout comme la partie avant 2b du corps 2 qui est disposée dans le prolongement du ventilateur.As illustrated in particular on figures 1 to 3 , the vacuum cleaner 1 comprises a body 2 which comprises a rear part 2a and a front part 2b. The rear part 2a comprises a first gripping handle 4 which the user can grip with the hand to manipulate the vacuum cleaner 1. The first gripping handle 4 is arranged in the lower part 1a of the vacuum cleaner 1. Preferably, the The vacuum cleaner 1 is electrically powered by means of a rechargeable battery (not shown) arranged in a base 5 which is assembled with the body 2 under the first gripping handle 4. The vacuum cleaner 1 comprises a tube 6 at the front end 6a from which impurities are sucked. This suction is provided by an air flow which generates a vacuum at the front end 6a of the tube 6. The rear part 2a of the body comprises a zone 7 in which is housed a fan (not shown) supplied by the battery, which makes it possible to generate said air flow flowing from the front to the rear of the vacuum cleaner 1. The fan is arranged in the upper part 1b of the vacuum cleaner 1, just like the front part 2b of the body 2 which is arranged in the extension of the fan.

Comme l'illustrent les figures 1 à 3, 6, 12 et 13, le corps 2 et le tube 6 forment un ensemble monobloc. Le tube 6 est disposé dans le prolongement avant de la partie avant 2b du corps 2. La partie avant 2b du corps 2 comporte un conduit 8 dont l'extrémité arrière 8a communique avec la zone 7 recevant le ventilateur (non illustré) et dont l'extrémité avant 8b débouche sur une face inférieure 2c du corps 2. Le tube 6 comprend un conduit 9 qui est distinct du conduit 8 sur le corps 2, bien que ces deux éléments (corps 2 et tube 6) forment un ensemble monobloc. Le conduit 9 du tube 6 débouche sur une ouverture arrière 10, au niveau de l'extrémité arrière 6b du tube 6, et sur une ouverture avant 11, à l'extrémité avant 6a du tube 6. Une pièce de brossage 12 est rapportée de manière amovible sur l'extrémité avant 6a du tube 6 grâce à des moyens d'encliquetage/décliquetage 13 prévus entre ladite pièce de brossage 12 et le tube 6 sur les deux côtés latéraux de l'aspirateur 1. Ces moyens d'encliquetage/décliquetage 13 sont de préférence constitués d'ergots 14 sur la pièce de brossage 12 qui s'engagent dans des pattes 15 sur le tube 6. On peut envisager l'ajout d'un tube de rallonge (non illustré) entre l'extrémité avant 6a du tube 6 et la pièce de brossage 12, ledit tube de rallonge comprenant sur chacun de ses côtés latéraux, au niveau de son extrémité arrière, un ergot similaire à l'ergot 14 pour son engagement sur l'extrémité avant 6a du tube 6 et, au niveau de son extrémité avant, une patte similaire à la patte 15 pour la réception de la pièce de brossage 12.As illustrated by figures 1 to 3 , 6, 12 and 13 , the body 2 and the tube 6 form a one-piece assembly. The tube 6 is disposed in the front extension of the front part 2b of the body 2. The front part 2b of the body 2 comprises a duct 8 whose rear end 8a communicates with the zone 7 receiving the fan (not shown) and whose l The front end 8b opens onto a lower face 2c of the body 2. The tube 6 comprises a duct 9 which is separate from the duct 8 on the body 2, although these two elements (body 2 and tube 6) form a single unit. The duct 9 of the tube 6 opens onto a rear opening 10, at the rear end 6b of the tube 6, and on a front opening 11, at the front end 6a of the tube 6. A brushing part 12 is attached to removable manner on the front end 6a of the tube 6 by means of latching / unclipping means 13 provided between said brushing part 12 and the tube 6 on the two lateral sides of the vacuum cleaner 1. These latching / unclipping means 13 are preferably made of lugs 14 on the brushing part 12 which engage in tabs 15 on the tube 6. It is possible to envisage adding an extension tube (not shown) between the front end 6a. of the tube 6 and the brushing part 12, said extension tube comprising on each of its lateral sides, at its rear end, a lug similar to the lug 14 for its engagement on the front end 6a of the tube 6 and , at its front end, a tab similar to the tab 15 for receiving the part brushing 12.

Tel qu'illustré en regard des figures 1 à 6, l'aspirateur 1 comprend un bol 17 qui peut être engagé sur le corps 2 pour former une chambre d'aspiration 18 ou, inversement, dégagé du corps 2 pour sa vidange et son nettoyage. Les mouvements du bol 17 vis-à-vis du corps 2, lors de son positionnement et de son extraction, sont définis par la présence d'un système de guidage et de maintien 19 agencé entre une face arrière 17a du bol 17 et une face avant 2d du corps 2. Comme l'illustrent plus en détail les figures 4, 5, 10 et 13, ce système de guidage et de maintien 19 comprend une came 20 agencée en partie inférieure de la face arrière 17a du bol 17 et un chemin de came 21 agencé en partie inférieure de la face avant 2d du corps 2.As illustrated next to figures 1 to 6 , the vacuum cleaner 1 comprises a bowl 17 which can be engaged on the body 2 to form a suction chamber 18 or, conversely, released from the body 2 for its emptying and cleaning. The movements of the bowl 17 vis-à-vis the body 2, during its positioning and its extraction, are defined by the presence of a guiding and holding system 19 arranged between a rear face 17a of the bowl 17 and a front face 2d of body 2. As illustrated in more detail by figures 4, 5 , 10 and 13 , this guiding and holding system 19 comprises a cam 20 arranged in the lower part of the rear face 17a of the bowl 17 and a cam track 21 arranged in the lower part of the front face 2d of the body 2.

Tel qu'illustré par exemple en figures 1 et 11, le bol 17 comprend sur sa face avant 17b une deuxième poignée de préhension 22 facilitant sa manipulation lors de son positionnement et de son extraction vis-à-vis du corps 2. Cette deuxième poignée de préhension 22 facilite également la manipulation du bol 17 durant sa vidange. En outre, lorsque le bol 17 est assemblé sur le corps 2, l'utilisateur peut saisir avec une main cette deuxième poignée de préhension 22 à l'avant de l'aspirateur 1 et, avec l'autre main, la poignée de préhension 4 à l'arrière du corps 2, ce qui facilite considérablement la manipulation de l'aspirateur 1 lors du nettoyage de surfaces rehaussées nécessitant de lever les bras.As illustrated for example in figures 1 and 11 , the bowl 17 comprises on its front face 17b a second gripping handle 22 facilitating its handling during its positioning and its extraction vis-à-vis the body 2. This second gripping handle 22 also facilitates the handling of the bowl 17 during its emptying. In addition, when the bowl 17 is assembled on the body 2, the user can grip with one hand this second gripping handle 22 at the front of the vacuum cleaner 1 and, with the other hand, the gripping handle 4 at the rear of the body 2, which considerably facilitates the handling of the vacuum cleaner 1 when cleaning raised surfaces requiring the lifting of the arms.

Selon l'invention, les axes longitudinaux des première 4 et deuxième 22 poignées de préhension sont sensiblement parallèles. Cette configuration améliore la prise en main de l'aspirateur et l'ergonomie.According to the invention, the longitudinal axes of the first 4 and second 22 gripping handles are substantially parallel. This configuration improves the handling of the vacuum cleaner and the ergonomics.

Une première extrémité de la deuxième poignée de préhension 22 est par exemple solidaire du bol 17 alors que la deuxième extrémité de la deuxième poignée 22 est montée sur le tube d'aspiration 6.A first end of the second gripping handle 22 is for example integral with the bowl 17 while the second end of the second handle 22 is mounted on the suction tube 6.

Tel qu'illustré en regard des figures 2 et 9 à 12, le bol 17 comprend sur sa partie supérieure arrière 17c une ouverture principale 23 et sur sa partie supérieure avant 17d une ouverture secondaire 24. L'ouverture principale 23 permet l'insertion d'un élément filtrant 25 composé de deux pièces, à savoir un séparateur 26 et un filtre 27. Le séparateur 26 permet de laisser passer uniquement les impuretés de petit calibre et le filtre 27 permet de bloquer ces impuretés de petit calibre pour ne laisser passer que l'air purifié. Le séparateur 26 est logé dans le bol 17 et comprend un bord externe 26a qui prend appui sur le bord supérieur 28 délimitant l'ouverture principale 23, un premier joint d'étanchéité 29 positionné sous le bord externe 26a assurant l'étanchéité entre le séparateur 26 et le bol 17. Le filtre 27 vient se loger dans le séparateur 26. Le filtre 27 comprend un couvercle 30 qui prend appui sur un bord interne 26b du séparateur 26. Un second joint d'étanchéité 31 est agencé sous le couvercle 30 et vient au contact dudit bord interne 26b, ce qui assure l'étanchéité entre le séparateur 26 et le filtre 27. Un troisième joint d'étanchéité 32 est agencé sur la face inférieure 2c du corps 2 et vient en appui sur le couvercle 30 du filtre 27 lors du verrouillage du bol 17 sur le corps 2, ce qui assure l'étanchéité entre le corps 2 et le filtre 27. Ainsi, lors de la mise en place du bol 17 sur le corps 2, l'étanchéité entre ces deux éléments est assurée par l'intermédiaire des trois joints d'étanchéité 29, 31, 32. Le couvercle 30 comprend en son centre une ouverture 33 qui communique avec une paroi filtrante 34 de forme conique s'étendant sous le couvercle 30, la porosité de cette paroi filtrante 34 permettant de bloquer les fines impuretés et de ne laisser passer que l'air purifié. L'ouverture 33 communique avec l'extrémité avant 8b du conduit 8 sur le corps 2, lorsque le bol 17 est en position assemblée. Le séparateur 26 comprend une paroi ajourée 35 de forme cylindrique ou conique qui laisse passer uniquement les fines impuretés, la paroi filtrante 34 étant logée dans la paroi ajourée 35. Lorsque le bol 17 est assemblé avec le corps 2, son ouverture secondaire 24 communique avec l'ouverture arrière 10 sur le tube 6. Un quatrième joint d'étanchéité 36 est agencé autour de l'ouverture arrière 10 sur le tube 6 et prend appui sur le contour 37 de l'ouverture secondaire 24 lors du verrouillage du bol 17 sur le corps 2.As illustrated next to figures 2 and 9 at 12 , the bowl 17 comprises on its upper rear part 17c a main opening 23 and on its upper front part 17d a secondary opening 24. The main opening 23 allows the insertion of a filter element 25 composed of two parts, namely a separator 26 and a filter 27. The separator 26 allows only small-caliber impurities to pass and the filter 27 makes it possible to block these small-caliber impurities to allow only purified air to pass. The separator 26 is housed in the bowl 17 and comprises an outer edge 26a which bears on the upper edge 28 delimiting the main opening 23, a first seal 29 positioned under the outer edge 26a ensuring the seal between the separator 26 and the bowl 17. The filter 27 is housed in the separator 26. The filter 27 comprises a cover 30 which bears on an inner edge 26b of the separator 26. A second seal 31 is arranged under the cover 30 and comes to the contact of said internal edge 26b, which ensures the seal between the separator 26 and the filter 27. A third seal 32 is arranged on the lower face 2c of the body 2 and bears on the cover 30 of the filter 27 during the locking of the bowl 17 on the body 2, which ensures the seal between the body 2 and the filter 27. Thus, when the bowl 17 is placed on the body 2, the seal between these two elements is ensured via the three seals 29, 31, 32. L The cover 30 comprises in its center an opening 33 which communicates with a filtering wall 34 of conical shape extending under the cover 30, the porosity of this filtering wall 34 making it possible to block the fine impurities and to allow only air to pass. purified. The opening 33 communicates with the front end 8b of the duct 8 on the body 2, when the bowl 17 is in the assembled position. The separator 26 comprises a perforated wall 35 of cylindrical or conical shape which allows only fine impurities to pass, the filtering wall 34 being housed in the perforated wall 35. When the bowl 17 is assembled with the body 2, its secondary opening 24 communicates with the rear opening 10 on the tube 6. A fourth seal 36 is arranged around the rear opening 10 on the tube 6 and bears on the contour 37 of the secondary opening 24 when locking the bowl 17 on body 2.

Tel qu'illustré notamment en regard des figures 2 à 6, la came 20 et le chemin de came 21 sont complémentaires et comprennent une forme plus ou moins coudée. Cette forme coudée est configurée pour engager le bol 17 sur le corps 2, tout d'abord en inclinant le bol 17 vers l'avant et le bas par rapport au corps 2 d'un angle de l'ordre de quarante degrés (40°) à cinquante degrés (50°), de préférence quarante-cinq degrés (45°), puis en translatant légèrement le bol 17 vers l'arrière vis-à-vis du corps 2 de manière à engager l'extrémité arrière 20a de la came 20 dans l'extrémité avant 21a du chemin de came 21 (voir figures 3 et 4) et, ensuite, en pivotant vers l'arrière et le haut le bol 17 vis-à-vis du corps 2 jusqu'à ce que la face arrière 17a du bol 17 vienne en appui contre la face avant 2d du corps 2 (voir figures 2 et 5). Dans cette position de la figure 2, le troisième joint d'étanchéité 32 sur la face inférieure 2c du corps 2 prend appui sur le couvercle 30 du filtre 27 et le quatrième joint d'étanchéité 36 prend appui sur le contour 37 de l'ouverture secondaire 24, la chambre d'aspiration 18 étant ainsi formée. En outre, la came 20 est complétement engagée dans le chemin de came 21, ce qui bloque non seulement les mouvements latéraux de la face arrière 17a du bol 17 vis-à-vis de la face avant 2d du corps 2, mais aussi le mouvements verticaux et horizontaux du bol 17 vis-à-vis du corps 2, assurant ainsi un maintien convenable de la partie arrière du bol 17 sur le corps 2. Le pivotement du bol 17 sur le corps 2 s'effectue naturellement, celui-ci étant guidé par la forme de la came 20 et du chemin de came 21.As illustrated in particular with regard to figures 2 to 6 , the cam 20 and the cam track 21 are complementary and comprise a more or less bent shape. This bent shape is configured to engage the bowl 17 on the body 2, first of all by tilting the bowl 17 forward and down with respect to the body 2 by an angle of the order of forty degrees (40 ° ) at fifty degrees (50 °), preferably forty-five degrees (45 °), then by slightly translating the bowl 17 towards the rear vis-à-vis the body 2 so as to engage the rear end 20a of the cam 20 in the front end 21a of the cam track 21 (see figures 3 and 4 ) and, then, by pivoting backwards and upwards the bowl 17 vis-à-vis the body 2 until the rear face 17a of the bowl 17 comes to rest against the front face 2d of the body 2 (see figures 2 and 5 ). In this position of the figure 2 , the third seal 32 on the lower face 2c of the body 2 bears on the cover 30 of the filter 27 and the fourth seal 36 bears on the contour 37 of the secondary opening 24, the chamber of suction 18 being thus formed. In addition, the cam 20 is completely engaged in the cam path 21, which not only blocks the lateral movements of the rear face 17a of the bowl 17 with respect to the front face 2d of the body 2, but also the movements vertical and horizontal of the bowl 17 vis-à-vis the body 2, thus ensuring proper retention of the rear part of the bowl 17 on the body 2. The pivoting of the bowl 17 on the body 2 takes place naturally, the latter being guided by the shape of the cam 20 and the cam track 21.

Afin de bloquer également les mouvements latéraux de la partie avant du bol 17 vis-à-vis du corps 2 et d'assurer le maintien du bol 17 avec la came 20 complètement engagée dans le chemin de came 21, la chambre d'aspiration 18 étant ainsi formée, l'aspirateur 1 comprend en complément un système de verrouillage 38 qui est mis en œuvre entre la partie supérieure avant 17d du bol 17 et la partie avant 2b du corps 2, plus ou moins dans une zone de jonction 39 entre ledit corps 2 et le tube 6 formant un ensemble monobloc. De préférence, comme l'illustrent les figures 1 à 3 et 6 à 8, le système d'assemblage 38 est déporté sous le tube 6 dans cette zone de jonction 39, ce qui est rendu possible du fait que le corps 2 et le tube 6 forment un ensemble monobloc, la partie avant 2b du corps 2 se confondant avec la partie arrière du tube 6.In order also to block the lateral movements of the front part of the bowl 17 vis-à-vis the body 2 and to ensure the maintenance of the bowl 17 with the cam 20 fully engaged in the cam track 21, the suction chamber 18 being thus formed, the vacuum cleaner 1 further comprises a locking system 38 which is implemented between the upper front part 17d of the bowl 17 and the front part 2b of the body 2, more or less in a junction zone 39 between said body 2 and tube 6 forming a one-piece assembly. Preferably, as illustrated in figures 1 to 3 and 6 to 8 , the assembly system 38 is offset under the tube 6 in this junction zone 39, which is made possible by the fact that the body 2 and the tube 6 form a single unit, the front part 2b of the body 2 coinciding with the rear part of the tube 6.

Une première réalisation du système de verrouillage 38 est décrite en regard des figures 6 à 8 et 11 et 12. Ce système de verrouillage 38 comprend un organe de commande 40 qui est agencé à l'avant de l'extrémité supérieure 22a de la seconde poignée de préhension 22 sur le bol 17. L'organe de commande 40 intègre dans sa partie supérieure une patte de transmission 41 qui comporte deux lumières 42, 43 permettant de transmettre un mouvement aux deux pênes 44, 45 afin de les déplacer en translation selon les flèches 46, 47 lorsque l'on appuie sur l'organe de commande 40. Ce mouvement permet de dégager les pênes 44, 45 des gâches 48, 49 formées sur la partie avant 2b du corps 2 par deux pattes 48a, 49a munies chacune d'un orifice 48b, 49b de réception des pênes 44, 45. Un premier ressort 50, agencé entre l'organe de commande 40 et la seconde poignée de préhension 22, et un second ressort 51 agencé entre les deux pênes 44, 45, permettent de ramener automatiquement ledit organe de commande 40 en position normale et les deux pênes 44, 45 en position engagée dans les gâches 48, 49. Les pênes 44, 45 comprennent chacun sur leur côté arrière un pan incliné 44a (seul celui du pêne 44 est illustré) qui prend appui sur les bords avant 52, 53 des pattes 48a, 49a en fin d'engagement du bol 17 sur le corps 2 (voir figures 6 et 7), ce qui permet d'escamoter automatiquement les pênes 44, 45 jusqu'à ce qu'ils reprennent leur position normale dans les gâches 48, 49 sous l'effet du second ressort 51, une fois qu'ils correspondent avec les orifices 48b, 49b (voir figure 8). On comprend donc que le verrouillage s'effectue automatiquement en fin d'engagement lors de la formation de la chambre de compression 18 et que le déverrouillage occasionné par l'actionnement de l'organe de commande 40 autorise le dégagement du bol 17 pour sa vidange et son nettoyage, ainsi que le nettoyage du séparateur 26 et du filtre 27. Lorsque l'organe de commande 40 est actionné, le bol 17 se positionne naturellement dans la position de la figure 6 grâce à la présence du troisième joint d'étanchéité 32 sur la face inférieure 2c du corps 2 qui exerce une poussée sur le couvercle 30 du filtre 27.A first embodiment of the locking system 38 is described with reference to the figures 6 to 8 and 11 and 12 . This locking system 38 comprises a control member 40 which is arranged at the front of the upper end 22a of the second gripping handle 22 on the bowl 17. The control member 40 incorporates in its upper part a tab of transmission 41 which comprises two slots 42, 43 making it possible to transmit a movement to the two bolts 44, 45 in order to move them in translation according to the arrows 46, 47 when the control member 40 is pressed. This movement makes it possible to release the bolts 44, 45 of the keeps 48, 49 formed on the front part 2b of the body 2 by two tabs 48a, 49a each provided with an orifice 48b, 49b for receiving the bolts 44, 45. A first spring 50, arranged between the control member 40 and the second gripping handle 22, and a second spring 51 arranged between the two bolts 44, 45, make it possible to automatically return said control member 40 to the normal position and the two bolts 44, 45 to the position engaged in the keeps 48, 49. The bolts 44, 45 each comprise on their rear side an inclined face 44a (only that of the bolt 44 is illustrated) which bears on the front edges 52, 53 of the tabs 48a, 49a at the end of engagement of the bowl 17 on body 2 (see figures 6 and 7 ), which allows the bolts 44, 45 to be automatically retracted until they return to their normal position in the keeps 48, 49 under the effect of the second spring 51, once they correspond with the holes 48b , 49b (see figure 8 ). It is therefore understood that the locking takes place automatically at the end of engagement during the formation of the compression chamber 18 and that the unlocking caused by the actuation of the control member 40 allows the release of the bowl 17 for its emptying. and its cleaning, as well as the cleaning of the separator 26 and of the filter 27. When the control member 40 is actuated, the bowl 17 is naturally positioned in the position of the filter. figure 6 thanks to the presence of the third seal 32 on the lower face 2c of the body 2 which exerts a thrust on the cover 30 of the filter 27.

Une seconde variante du système de verrouillage 38 est illustrée en figures 14 et 15. Cette variante comprend un organe de commande 40 qui peut être similaire à celui précédemment décrit. Cet organe de commande 40 est cependant assujetti à un crochet 54 dont l'extrémité recourbée 55 vient s'engager dans un bord 56 agencé dans la zone de jonction 39, comme l'illustre la figure 14, ce qui assure le verrouillage du bol 17 sur le corps 2 lorsque la chambre d'aspiration 18 est formée. Le verrouillage de l'extrémité recourbée 55 dans le bord 56 s'effectue automatiquement en fin d'engament du bol 17 sur le corps 2. Pour cela, l'extrémité recourbée 55 comprend un pan incliné 57 prenant appui sur une face inclinée 58 s'étendant vers l'avant en-dessous du bord 56. Un ressort (non illustré) semblable au premier ressort 50 permet le rappel de l'organe de commande 40, comme précédemment. On comprend que, selon cette variante, la transmission du mouvement au crochet 54 est assurée directement par l'organe de commande 40. On pourrait cependant prévoir un élément de transmission additionnel entre l'organe de commande 40 et le crochet 54.A second variant of the locking system 38 is illustrated in figures 14 and 15 . This variant comprises a control member 40 which may be similar to that previously described. This control member 40 is however secured to a hook 54 whose curved end 55 engages an edge 56 arranged in the junction zone 39, as illustrated by figure 14 , which ensures the locking of the bowl 17 on the body 2 when the suction chamber 18 is formed. The locking of the curved end 55 in the edge 56 takes place automatically at the end of the engagement of the bowl 17 on the body 2. For this, the curved end 55 comprises an inclined face 57 bearing on an inclined face 58 s extending forwardly below edge 56. A spring (not shown) similar to first spring 50 allows actuator 40 to be returned as before. It is understood that, according to this variant, the transmission of the movement to the hook 54 is ensured directly by the control member 40. However, an additional transmission element could be provided between the control member 40 and the hook 54.

On pourra bien entendu envisager des variantes de l'aspirateur 1 sans sortir du cadre de l'invention. Des variantes du système de guidage et de maintien 19 peuvent notamment être envisagées en modifiant la forme de la came 20 et du chemin de came 21, ce qui modifiera sensiblement la trajectoire du bol 17 vis-à-vis du corps 2 lors de son engagement ou de son dégagement.It is of course possible to envisage variants of the vacuum cleaner 1 without departing from the scope of the invention. Variants of the guiding and holding system 19 can in particular be envisaged by modifying the shape of the cam 20 and of the cam track 21, which will substantially modify the trajectory of the bowl 17 with respect to the body 2 when it is engaged. or its release.

On peut également envisager des variantes du système de verrouillage 38 sans sortir du cadre de l'invention.It is also possible to envisage variants of the locking system 38 without departing from the scope of the invention.
