Description

L'invention qui se rapporte à un aspirateur industriel à moteur autonome,The invention which relates to an industrial vacuum cleaner with autonomous motor,

plus particulièrement destiné à être monté sur un châssis mobile en vue de l'aspiration de déchets urbains, concerne plus précisément le couvercle d'aspiration monté sur la cuve de réception des déchets. Dans les aspirateurs de type connu et notamment les aspirateurs ménagers, on sait que la dépression est assurée par un ventilateur à turbine qui entraîne les poussières collectées par un tube vers un sac ou un filtre qui est perméable au passage d'air mais imperméable auxdites poussières ce qui permet leur rétention et leur stockage. Ce filtre  more particularly intended to be mounted on a movable frame for the suction of urban waste, more specifically relates to the suction cover mounted on the waste receiving tank. In vacuum cleaners of known type and in particular household vacuum cleaners, it is known that the vacuum is ensured by a turbine fan which drives the dust collected by a tube towards a bag or a filter which is permeable to the passage of air but impermeable to said dust which allows their retention and storage. This filter

empêche aussi que les poussières ne pénètrent dans la turbine.  also prevents dust from entering the turbine.

Les aspirateurs industriels et urbains doivent avoir évidemment une plus forte capacité d'aspiration pour 15 pouvoir absorber non seulement des poussières, mais aussi d'autres débris comme des feuilles ou des papiers, des déchets organiques, des ferrailles, des bouteilles etc... Aussi plutôt que d'utiliser des filtres, dans la mesure o une finesse particulière de filtration n'est pas exigée, on fait 20 en sorte que l'organe d'aspiration soit protégé par une  Industrial and urban vacuum cleaners must obviously have a higher suction capacity in order to be able to absorb not only dust, but also other debris such as sheets or papers, organic waste, scrap metal, bottles, etc. Also rather than using filters, insofar as a particular fineness of filtration is not required, provision is made for the suction member to be protected by a

grille contre laquelle viendront buter les débris aspirés qui seront ensuite recueillis dans une cuve de réception.  grid against which the sucked debris will come up against which will then be collected in a receiving tank.

Pour éviter que cette grille ne soit rapidement colmatée par les corps aspirés, et notamment les matières légères comme les feuilles ou morceaux de papier, on connaît le système qui consiste à faire tourner rapidement cette grille pour dégager ainsi les débris par centrifugation. Il faut donc prévoir à cet effet un mécanisme moteur pour l'entra;nement de la grille et une chambre de détente de l'air tra3C versant la grille, adaptée à cette dernière. Cela rend le système plus difficile à mettre en oeuvre et par conséquent  To prevent this grid from being quickly clogged by sucked bodies, and in particular light materials such as sheets or pieces of paper, the system is known which consists in rapidly rotating this grid to thereby release the debris by centrifugation. It is therefore necessary to provide for this purpose a motor mechanism for driving the grid and an air expansion chamber tra3C pouring the grid, adapted to the latter. This makes the system more difficult to implement and therefore

moins fiable.less reliable.

Un objet de la présente invention est de proposer un aspirateur industriel à moteur autonome, utilisant aussi une grille, mais dont le couvercle d'aspiration monté sur la cuve de réception des débris est d'une conception tout à fait particulière, qui évite les inconvénients propres aux appareils connus, et qui présente en outre l'avantage de se prêter à un montage aisé de l'ensemble d'aspiration sur un châssis mobile, ce qui le rend particulièrement efficace  An object of the present invention is to provide an industrial vacuum cleaner with autonomous motor, also using a grid, but whose suction cover mounted on the debris receiving tank is of a completely particular design, which avoids the disadvantages specific to known devices, and which also has the advantage of being easy to mount the suction assembly on a movable frame, which makes it particularly effective

pour le nettoyage urbain.for urban cleaning.

Selon une caractéristique principale de l'invention le couvercle d'aspiration délimitant un volume de détente entre le point de pénétration du tube d'aspiration et l'ouie d'aspiration de la turbine est fermé à sa partie  According to a main characteristic of the invention, the suction cover delimiting an expansion volume between the point of penetration of the suction tube and the suction opening of the turbine is partially closed.

inférieure au niveau du sommet de la cuve par une grille et 15 une partie terminale du tube d'aspiration est munie de perforations sur au moins une partie de la hauteur de la chambre de détente et traverse la grille.  below the level of the top of the tank by a grid and an end part of the suction tube is provided with perforations over at least part of the height of the expansion chamber and passes through the grid.

Selon une autre caractéristique particulière de l'invention, la partie terminale du tube d'aspiration, 20 qui déborde sous la grille est munie sur toute sa hauteur  According to another particular characteristic of the invention, the end part of the suction tube, which projects beyond the grid, is provided over its entire height.

de perforations avantageusement disposées en quinconce.  perforations advantageously arranged in staggered rows.

Figure 5: une vue schématique en coupe verticale de l'aspirateur selon la figure 1.  Figure 5: a schematic view in vertical section of the vacuum cleaner according to Figure 1.

On a représenté aux figures 1 et 2 un aspirateur industriel essentiellement constitué d'une cuve de réception 1 coiffée d'un couvercle 2 surmontée d'une turbine d'aspiration 3 entraînée par un moteur autonome 4. Un tube flexible de gros diamètre supporté par une potence 5 manoeuvrée par un vérin 6 peut prendre diverses orientations et son extrémité non représentée peut couvrir une surface voisine du sol. Le tube flexible d'aspiration 7 débouche à l'intérieur de la cuve en traversant le couvercle 2 par un orifice 10 15. La turbine 3 est logée dans un collecteur et rejette vers l'extérieur l'air aspiré par la buse de sortie 8. L'ensemble que constituent la turbine 3, le moteur 4, le tube flexible 7 et ses dispositifs de maintien est avantageusement monté sur un support non représenté lui-même porté par un châssis mo15 bile du genre d'un chariot ou d'une voiturette. Le support est par exemple pivotant par rapport à la cuve 1 pour permettre d'enlever le couvercle 2. Bien entendu, en position travail, un orifice inférieur de la turbine 3 vient s'adapter de façon étanche sur un orifice supérieur 16 correspondant du 20 couvercle 2 formant une ouie d'aspiration, mais l'ensemble moto ventilateur (3,4) n'est pas supporté directement par le couvercle. On notera que les orifices 15 et 16 prévus dans le couvercle sont excentrés, ce qui permet au tube d'aspiration de déboucher sur le côté de la cuve et de faciliter l'aspiration. La turbine 3 peut être ainsi montée excentrée  FIGS. 1 and 2 show an industrial vacuum cleaner essentially consisting of a receiving tank 1 capped with a cover 2 surmounted by a suction turbine 3 driven by an autonomous motor 4. A flexible tube of large diameter supported by a bracket 5 maneuvered by a jack 6 can take various orientations and its end, not shown, can cover a surface close to the ground. The flexible suction tube 7 opens into the interior of the tank, passing through the cover 2 through an orifice 10 15. The turbine 3 is housed in a manifold and rejects the air sucked out through the outlet nozzle 8 The assembly constituted by the turbine 3, the motor 4, the flexible tube 7 and its holding devices is advantageously mounted on a support not shown itself carried by a mo15 bile chassis of the kind of a carriage or a cart. The support is for example pivotable relative to the tank 1 to allow the cover 2 to be removed. Of course, in the working position, a lower orifice of the turbine 3 fits tightly on an upper orifice 16 corresponding to the 20 cover 2 forming a suction opening, but the motor-driven fan assembly (3,4) is not supported directly by the cover. Note that the openings 15 and 16 provided in the cover are eccentric, which allows the suction tube to open on the side of the tank and facilitate suction. The turbine 3 can thus be mounted eccentrically

sans nuire au fonctionnement.without affecting the operation.

Les figures 3, 4 et 5 montrent la disposition particulière du couvercle 2 qui s'emboîte au-dessus de la cuve 1. Il est muni à sa partie inférieure d'une grille 9 au niveau du sommet de la cuve et d'un joint 10 lui permettant de faire étanchéité sur la bordure supérieure de la cuve. La  Figures 3, 4 and 5 show the particular arrangement of the cover 2 which fits over the tank 1. It is provided at its lower part with a grid 9 at the top of the tank and a seal 10 allowing it to seal on the upper edge of the tank. The

grille 9 délimite avec le couvercle une chambre de détente 17.  grid 9 defines with the cover an expansion chamber 17.

Le tube flexible d'aspiration 7 comporte une partie terminale 11 qui traverse à la fois le couvercle 2 35 et la grille 9 et s'ouvre vers la cuve par un orifice 13.  The flexible suction tube 7 has an end portion 11 which passes through both the cover 2 35 and the grid 9 and opens towards the tank through an orifice 13.

Cette partie terminale déborde de quelques centimètres sous la grille. Audessous du couvercle, cette partie 11 est munie de petites perforations 12 qui couvrent toute sa surface. On voit plus précisément aux figures 4 et 5 la disposition de ces perforations ainsi que les mailles de la grille 9, empêchant les débris d'atteindre la turbine. Ces perforations 12 font tout le tour de la partie 11 et sont avantageusement  This terminal part extends a few centimeters below the grid. Below the cover, this part 11 is provided with small perforations 12 which cover its entire surface. We see more precisely in Figures 4 and 5 the arrangement of these perforations and the meshes of the grid 9, preventing debris from reaching the turbine. These perforations 12 go all around part 11 and are advantageously

disposées en quinconce.arranged in staggered rows.

Grâce à cette disposition, l'air aspiré par la turbine 3, suit le cheminement indiqué par les flèches.  Thanks to this arrangement, the air sucked in by the turbine 3 follows the path indicated by the arrows.

Un certain débit d'air Q porteur de débris traverse le cou10 vercle de haut en bas et sort dans la cuve par l'orifice 13.  A certain flow of air Q carrying debris crosses the neck 10 from top to bottom and exits into the tank through the orifice 13.

Une autre fraction de débit d'air Q, traverse les perforations 12 et atteint directement la turbine sans passer par la cuve,  Another fraction of air flow Q, crosses the perforations 12 and directly reaches the turbine without passing through the tank,

formant ainsi un bipass du circuit principal.  thus forming a bypass of the main circuit.

Le débit d'air total dans le tube 7 est la somme 15 des débits Q et Q,. Il y a donc au niveau de l'orifice 13 de la section terminale 11 du tube, c'est-à-dire dans le volume de détente compris entre le point de pénétration du tube 7 dans le couvercle 2 et l'ouie d'aspiration de la turbine 3, une diminution du débit de l'air porteur, qui ne 20 gêne en rien le dépôt des débris 14 sur le fond de la cuve 1, du fait de leur vitesse acquise, mais qui limite dans celle-ci les mouvements tourbillonnaires de l'air du fait de son impact sur le fond et les parois. Les déchets les plus légers comme les papiers, feuilles plastiques ou autres ne se trouvent donc pas attirés vers la grille 9 par un flux d'air ascendant important en direction de la turbine 3, du fait justement du flux compensateur QI s'établissant transversalement dans le couvercle. On évite ainsi le colmatace de la grille 9 par les  The total air flow rate in the tube 7 is the sum of the flow rates Q and Q ,. There is therefore at the orifice 13 of the end section 11 of the tube, that is to say in the expansion volume comprised between the point of penetration of the tube 7 in the cover 2 and the hearing suction of the turbine 3, a reduction in the flow rate of the carrier air, which does not hinder in any way the deposition of debris 14 on the bottom of the tank 1, because of their acquired speed, but which limits therein the swirling movements of air due to its impact on the bottom and walls. The lightest waste such as paper, plastic sheets or the like is therefore not attracted towards the grid 9 by a significant upward air flow towards the turbine 3, precisely because of the compensating flow QI establishing itself transversely in lid. This avoids the clogging of the grid 9 by the

débris légers sans diminuer d'aucunc façon la force globale 30 d'aspiration de l'appareil.  light debris without in any way reducing the overall suction force of the apparatus.
