Description

ASPIRATEUR DE POUSSIERE DUST VACUUM
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 dust vacuum cleaner comprising a first compartment, delimited by a shell of which a front part has a rigid structure, and which contains a turbine powered by a motor, and a second compartment, constituting a vacuum chamber, which communicates with the first compartment by an air passage formed in the front part, a cover pivotally mounted on the front part defining with it the second compartment when said cover is in the closed position such that external faces of the rigid front part cooperate with of the internal faces of the cover.
Dans les appareils connus de ce type, 1 ' 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, the seal between the vacuum chamber and the outside is generally produced by an attached gasket and disposed on the external faces of the front part of the shell intended to cooperate with the internal faces of the cover, so that this seal is slightly crushed when the cover is closed on the hull; such a seal is an expensive piece because it must be made of a flexible material resistant to crushing and wear. In this configuration, the cover is made of a rigid material, generally identical to the material that makes up the front part of the shell, 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. 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.However, such an arrangement has the disadvantage of increasing the cost of manufacturing this type of device, due to the manufacturing operations and possibly the mounting of the seal. The main object of the invention is to remedy this drawback, namely to seal the vacuum chamber by reducing the number of parts making up the device.
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 of a plastic material of elasticity substantially greater than that of the material forming the rigid front part, and the assembly of the cover 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 be substantially deformed under the effect of the vacuum created in the second compartment, so that the external faces of the rigid front part and the internal faces of the cover cooperate in an adhesive connection reinforcing friction, and therefore perfectly waterproof, without the need for the addition of a seal.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée qui va suivre, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels: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:
- la figure 1 est une vue partielle en perspective avec arrachement, d'un aspirateur suivant l'invention, le capot étant en position ouverte;- Figure 1 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the open position;
- la figure 2 est une vue partielle en perspective avec arrachement, d'un aspirateur suivant l'invention, le capot étant en position fermée;- Figure 2 is a partial perspective view with cutaway, of a vacuum cleaner according to the invention, the cover being in the closed position;
- 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;- 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 vacuum cleaner 1 according to the invention, which comprises a first compartment 2, delimited by a shell 2 'of which a front part 3 has a rigid structure. This shell has a housing 5 for receiving a turbine actuated by a motor power, 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 le 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'emboîte 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 - and 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 rigid front part 3 and by a separation face 4 of this rigid front part, when the cover 8 is in the closed position. In this position, the cover 8 fits onto the rigid front part 3, so that external faces 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 made of a plastic material of elasticity substantially greater than that of the material forming the rigid front part 3, and the assembly of the cover 8 on the rigid front part 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 etanche. 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 _.es 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.Thus, when a vacuum is generated in the second compartment 6, due to the powering 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 them 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 hand, as well as the tight connection between _.es two parts, allow to obtain such a quality of sealing, necessary reliable operation of the device, without resorting to a gasket. This results in a reduction in the number of parts making up the device, and consequently in the manufacturing cost.
De préférence, l'assemblage est du type conique et les faces externes 9 présentent à cet effet une pente 9' d' emboîtement 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 nesting slope 9 ′ of shape complementary to that of the internal faces 10 of the 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 epaulement 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 FIG. 2, the same dust vacuum cleaner is shown, the 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 peripheral shoulder 11 of the front part rigid 3. A projecting member 13 formed on the rigid front part 3 has a housing 18 intended to receive an elastic locking member - not shown and known per se - which, by cooperating with a cavity 14 formed on a wall of the cover 8, secures the closing of the cover, before powering up the device.
De façon déjà connue en soi, la partie antérieure rigide 3 est par exemple réalisée en Acrylonitπle 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. Le capot 8 et la coque 2' sont eux, de préférence, constitués de polypropylène copolymere, matériau qui en plus de ses caractéristiques d'élasticité relative, présente un coût inférieur à celui de l'ABS.In a manner already known per se, the rigid front part 3 is for example made of Acrylonitπle Butadiene Styrene, also designated by the acronym ABS, whose important characteristics in this type of manufacture are rigidity, lightness and impact resistance. The cover 8 and the shell 2 ′ are preferably made of copolymer polypropylene, a material which, in addition to its characteristics of relative elasticity, has a lower cost than that of 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 with respect to the devices of the prior art, with a significantly lower manufacturing cost due to the removal of the seal, also due to the replacement in the composition of the cover, of ABS by a material of lower 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 longitudinal plane of symmetry of the device, in the respectively open and closed positions of the cover.
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 epaulement 16 destiné, en coopérant avec le bord 17 de la partie du capot comportant la cavité 14, à limiter l'emboîtement de ce dernier.The protruding member 13 ensures the continuity of 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 comprises a shoulder 16 intended, by cooperating with the edge 17 of the part of the cover comprising the cavity 14, to limit 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 described above that a dust vacuum cleaner according to the present invention has a reduced cost and a more constant reliability over time, due to the removal of the seal which constitutes a part liable to deterioration.
