Description

L'invention se rapporte à un aspirateur de poussière comprenant un premier compartiment, délimité par une coque dont une partie antérieure présente une structure rigide, et qui contient une turbine actionnée par un moteur, et un deuxième compartiment, constituant une chambre de dépression, qui communique avec le premier compartiment par un passage d'air formé dans la partie antérieure, un capot monté pivotant sur la partie antérieure délimitant avec elle le deuxième compartiment lorsque ledit capot est en position fermée telle que des faces externes de la partie antérieure rigide coopèrent avec des faces internes du capot.The invention relates to a vacuum cleaner dust including a first compartment, delimited by a shell of which a front part presents a rigid structure, and which contains a powered turbine by a motor, and a second compartment, constituting a vacuum chamber, which communicates with the first compartment by an air passage formed in the part front, a cover pivotally mounted on the part anterior delimiting with it the second compartment when said cover is in the closed position such that external faces of the rigid front part cooperate with internal faces of the cover.

Dans les appareils connus de ce type tel celui décrit dans le document EP 0 839 490, l'étanchéité entre la chambre de dépression et l'extérieur est généralement réalisée par un joint rapporté et disposé sur les faces externes de la partie antérieure de la coque destinées à coopérer avec les faces internes du capot, de façon que ce joint subisse un léger écrasement lors de la fermeture du capot sur la coque; un tel joint est une pièce onéreuse car il doit être réalisé en un matériau souple résistant à l'écrasement et à l'usure. Dans cette configuration, le capot est fabriqué dans une matière rigide, généralement identique à la matière qui compose la partie antérieure de la coque, ou même la coque dans son ensemble.In known devices of this type such as that described in document EP 0 839 490, the seal between the vacuum chamber and the exterior is generally carried out by an attached and arranged seal on the external faces of the anterior part of the shell intended to cooperate with the internal faces of the cover, so that this seal is slightly crushed when closing the cover on the hull; such a joint is an expensive piece because it must be made in one soft material resistant to crushing and wear. In this configuration, the cover is manufactured in a rigid material, generally identical to the material which composes the front part of the hull, or even the shell as a whole.

Une telle disposition présente cependant l'inconvénient de grever le coût de fabrication de ce type d'appareil, du fait des opérations de fabrication et éventuellement de montage du joint. However, such a provision presents the disadvantage of burdening the manufacturing cost of this type of device, due to manufacturing operations and possibly mounting the seal.

L'objet principal de l'invention est de remédier à cet inconvénient, à savoir de réaliser l'étanchéité de la chambre de dépression en réduisant le nombre de pièces composant l'appareil.The main object of the invention is to remedy this drawback, namely to seal the vacuum chamber by reducing the number of parts component of the device.

Ce but est atteint par l'aspirateur selon la revendication 1. Des modes de réalisation particuliers sont définis dans les revendications dépendantes.This object is achieved by the vacuum cleaner according to claim 1. Particular embodiments are defined in the dependent claims.

Selon l'invention, le capot est réalisé dans un matériau plastique d'élasticité sensiblement supérieure à celle du matériau formant la partie antérieure rigide, et l'assemblage du capot sur la partie antérieure rigide constitue un emmanchement à force.According to the invention, the cover is made in a plastic material with elasticity substantially greater than that of the material forming the rigid front part, and the assembly of the hood on the rigid front part constitutes a press fit.

Grâce à cette disposition, le capot peut sensiblement se déformer sous l'effet de la dépression créée dans le deuxième compartiment, de sorte que les faces externes de la partie antérieure rigide et les faces internes du capot coopèrent en une liaison adhérente renforçant la friction, et donc parfaitement étanche, sans que soit nécessaire l'adjonction d'un joint.Thanks to this arrangement, the cover can significantly deform under the effect of depression created in the second compartment, so that the external faces of the rigid front part and the internal faces of the cover cooperate in a connection adherent reinforcing friction, and therefore perfectly waterproof, without the need for the addition of a seal.

D'autres caractéristiques et avantages de l'invention apparaítront dans la description détaillée qui va suivre, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels:

  • la figure 1 est une vue partielle en perspective avec arrachement, d'un aspirateur suivant l'invention, le capot étant en position ouverte;
  • la figure 2 est une vue partielle en perspective avec arrachement, d'un aspirateur suivant l'invention, le capot étant en position fermée;
  • la figure 3 est une vue partielle en coupe d'un aspirateur suivant l'invention, le capot étant en position ouverte;
  • la figure 4 est une vue partielle en coupe d'un aspirateur suivant l'invention, le capot étant en position fermée;
Other characteristics and advantages of the invention will appear in the detailed description which follows, given by way of nonlimiting example, with reference to the appended drawings in which:
  • Figure 1 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the open position;
  • Figure 2 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the closed position;
  • Figure 3 is a partial sectional view of a vacuum cleaner according to the invention, the cover being in the open position;
  • Figure 4 is a partial sectional view of a vacuum cleaner according to the invention, the cover being in the closed position;

La figure 1 montre un aspirateur de poussière 1 conforme à l'invention, qui comprend un premier compartiment 2, délimité par une coque 2' dont une partie antérieure 3 présente une structure rigide. Cette coque présente un logement 5 destiné à recevoir une turbine actionnée par un moteur électrique, non représenté.Figure 1 shows a dust extractor 1 according to the invention, which comprises a first compartment 2, delimited by a 2 'shell, part of which front 3 has a rigid structure. This shell has a housing 5 intended to receive a turbine powered by an electric motor, not shown.

L'aspirateur présente un deuxième compartiment 6 constituant la chambre de dépression, qui peut contenir un sac à poussière - non représenté - et qui communique avec l'extérieur par une embouchure (E) et avec lé premier compartiment 2 par un passage d'air 7 formé dans la partie antérieure rigide 3. Ce deuxième compartiment 6 est délimité par un capot 8 monté pivotant sur la partie antérieure rigide 3 et par une face de séparation 4 de cette partie antérieure rigide, lorsque le capot 8 est en position fermée. Dans cette positon, le capot 8 s'emboíte sur la partie antérieure rigide 3, de sorte que des faces externes 9 de la partie antérieure rigide 3 coopèrent avec des faces internes 10 du capot.The vacuum cleaner has a second compartment 6 constituting the vacuum chamber, which can contain a dust bag - not shown - which communicates with the outside by a mouth (E) and with the first compartment 2 by an air passage 7 formed in the rigid front part 3. This second compartment 6 is delimited by a cover 8 pivotally mounted on the part rigid anterior 3 and by a separation face 4 of this rigid front part, when the cover 8 is in closed position. In this position, the cover 8 fits on the rigid front part 3, so that faces external 9 of the rigid front part 3 cooperate with internal faces 10 of the cover.

Selon l'invention, le capot 8 est réalisé dans un matériau plastique d'élasticité sensiblement supérieure à celle du matériau formant la partie antérieure rigide 3, et l'assemblage du capot 8 sur la partie antérieure rigide 3 constitue un emmanchement à force.According to the invention, the cover 8 is produced in a plastic material with elasticity substantially greater than that of the material forming the rigid front part 3, and the assembly of the cover 8 on the front part rigid 3 constitutes a press fit.

Ainsi, lorsqu'une dépression est générée dans le deuxième compartiment 6, du fait de la mise sous tension de l'appareil, le capot 8 subit une légère déformation sous l'effet de laquelle ses faces internes 10 en contact avec les parois externes 9 de la partie antérieure rigide 3, sont plaquées contre ces dernières en formant avec elles une liaison adhérente et parfaitement étanche. La rigidité relative des matériaux constituant le capot 8 d'une part, et la partie antérieure rigide 3 d'autre part, ainsi que l'assemblage serré entre les deux pièces, permettent d'obtenir une telle qualité d'étanchéité, nécessaire à un fonctionnement fiable de l'appareil, sans recourir pour autant à un joint d'étanchéité. Il s'ensuit une réduction du nombre de pièces constituant l'appareil, et par conséquent du coût de fabrication.So when a depression is generated in the second compartment 6, due to power-up of the device, the cover 8 undergoes a slight deformation under the effect of which its internal faces 10 in contact with the external walls 9 of the rigid front part 3, are pressed against the latter forming with they an adherent and perfectly waterproof connection. The relative rigidity of the materials constituting the cover 8 on the one hand, and the rigid front part 3 on the other part, as well as the tight connection between the two parts, allow to obtain such a seal quality, necessary for reliable operation of the device, without however, use a seal. It follows a reduction in the number of parts making up the device, and therefore the manufacturing cost.

De préférence, l'assemblage est du type conique et les faces externes 9 présentent à cet effet une pente 9' d'emboítement de forme complémentaire à celle des faces internes 10 du capot 8.Preferably, the assembly is of the conical type and the external faces 9 for this purpose have a slope 9 ' interlocking shape complementary to that of the faces internal 10 of cover 8.

A la figure 2, on a représenté le même aspirateur de poussière, le capot 8 étant dans sa position fermée sur la partie antérieure rigide 3, position dans laquelle le bord 12 du capot 8 est en butée sur un épaulement périphérique 11 de la partie antérieure rigide 3. Un organe saillant 13 formé sur la partie antérieure rigide 3, présente un logement 18 destiné à recevoir un organe élastique de verrouillage - non représenté et connu en soi -, qui, en coopérant avec une cavité 14 formée sur une paroi du capot 8, permet de sécuriser la fermeture du capot, avant mise sous tension de l'appareil.In Figure 2, the same vacuum cleaner is shown dust, cover 8 being in its closed position on the rigid front part 3, position in which the edge 12 of the cover 8 is in abutment on a shoulder peripheral 11 of the rigid front part 3. A protruding member 13 formed on the rigid front part 3, has a housing 18 intended to receive an organ locking elastic - not shown and known in soi -, which, by cooperating with a cavity 14 formed on a wall of the cover 8, makes it possible to secure the closing of the cover, before switching on the device.

De façon déjà connue en soi, la partie antérieure rigide 3 est par exemple réalisée en Acrylonitrile Butadiène Styrène, désigné également par le sigle ABS, dont des caractéristiques importantes dans ce type de fabrication sont la rigidité, la légèreté et la résistance aux chocs. In a manner already known per se, the front part rigid 3 is for example made of Acrylonitrile Butadiene Styrene, also designated by the acronym ABS, which important features in this type of manufacturing are rigidity, lightness and impact resistance.

Le capot 8 et la coque 2' sont eux, de préférence, constitués de polypropylène copolymère, matériau qui en plus de ses caractéristiques d'élasticité relative, présente un coût inférieur à celui de l'ABS.The cover 8 and the shell 2 'are preferably made of polypropylene copolymer, a material which more of its relative elasticity characteristics, has a lower cost than ABS.

Un aspirateur du type proposé par l'invention allie donc une efficacité équivalente par rapport aux appareils de la technique antérieure, à un coût de fabrication nettement inférieur du fait de la suppression du joint, du fait en outre du remplacement dans la composition du capot, de l'ABS par une matière de plus bas prix.A vacuum cleaner of the type proposed by the invention therefore combines equivalent efficiency compared to prior art devices at a cost of significantly lower manufacturing due to the elimination of the seal, also due to the replacement in the composition of the cover, of ABS by one more material low price.

Les figures 3 et 4 montrent l'appareil selon l'invention, suivant des coupes simplifiées dans le plan longitudinal de symétrie de l'appareil, dans les positions respectivement ouverte et fermée du capot.Figures 3 and 4 show the device according to the invention, according to simplified sections in the plan longitudinal symmetry of the device, within hood open and closed positions respectively.

L'organe saillant 13 assure la continuité d'étanchéité par coopération de sa face externe 15 avec la face interne du capot, dans sa partie comportant la cavité 14; ledit organe saillant 13 comporte également un épaulement 16 destiné, en coopérant avec le bord 17 de la partie du capot comportant la cavité 14, à limiter l'emboítement de ce dernier.The protruding member 13 ensures continuity sealing by cooperation of its external face 15 with the internal face of the cover, in its part comprising the cavity 14; said projecting member 13 also includes a shoulder 16 intended, cooperating with the edge 17 of the part of the cover comprising the cavity 14, to be limited the nesting of the latter.

Il découle de la structure précédemment décrite qu'un aspirateur de poussière suivant la présente invention, présente un coût réduit et une fiabilité plus constante dans le temps, due à la suppression du joint qui constitue une pièce susceptible de dégradation.It follows from the structure previously described that a vacuum cleaner according to the present invention, presents a reduced cost and more reliability constant over time, due to the removal of the joint which constitutes a part liable to deterioration.
