Description

La présente invention concerne un circuit d'aspiration pour un suceur d'aspirateur et plus particulièrement un suceur d'aspirateur possédant une semelle, un conduit d'évacuation relié à un circuit de circulation d'air composé d'un circuit d'aspiration et d'une veine d'écoulement triangulaire située sur la semelle et ouverte vers la surface à nettoyer.The present invention relates to a circuit for a vacuum cleaner nozzle and more particularly a vacuum cleaner nozzle with a soleplate, an evacuation pipe connected to a air circulation composed of a suction circuit and a triangular flow vein located on the sole and open to the surface to be cleaned.

L'invention concerne également un aspirateur comportant un tel suceur.The invention also relates to a vacuum cleaner. comprising such a nozzle.

Il est connu, par le document US 1,533,368, un suceur de forme triangulaire, possédant une veine d'aspiration triangulaire, et dont le circuit de circulation d'air présente la forme d'une pyramide, vers le sommet de laquelle est connecté un tube d'évacuation des déchets.It is known, from document US 1,533,368, a triangular nozzle, with a vein of triangular suction, and whose circuit air circulation has the shape of a pyramid, towards the the top of which is connected a waste.

Un tel suceur est relativement encombrant, notamment par sa hauteur. Par ailleurs, les ouvertures d'aspiration présentent des surfaces importantes qui limitent les performances d'aspiration.Such a nozzle is relatively bulky, especially by its height. Furthermore, the openings have large areas which limit suction performance.

Le but de l'invention est de pallier aux inconvénients mentionnés ci-dessus.The object of the invention is to overcome the disadvantages mentioned above.

Un autre but de l'invention est d'éviter les collisions entre les flux d'air rentrant dans le circuit de circulation d'air. Ces collisions frontales provoquent des phénomènes d'instationnarité aéraulique, causent des pertes de charges et génèrent un bruit. Another object of the invention is to avoid collisions between the air flows entering the circuit air circulation. These head-on collisions cause aeraulic stationarity phenomena, cause losses of charges and generate noise.

La présente invention est atteinte à l'aide d'un suceur d'aspirateur possédant une semelle, un conduit d'évacuation relié à un circuit de circulation d'air composé d'un circuit d'aspiration et d'une veine d'écoulement triangulaire située sur la semelle et ouverte vers la surface à nettoyer, caractérisé en ce que la veine d'écoulement comporte quatre ouvertures d'aspiration formant un rectangle virtuel, le circuit d'aspiration se présentant sous la forme d'un H au milieu duquel débouche le conduit d'évacuation des déchets.The present invention is achieved using a vacuum cleaner nozzle with sole, conduit exhaust connected to an air circulation circuit composed of a suction circuit and a vein triangular flow located on the sole and open towards the surface to be cleaned, characterized in that the vein outlet has four suction openings forming a virtual rectangle, the suction circuit is having the form of an H in the middle of which opens the waste evacuation pipe.

Un tel suceur, présente ainsi une veine de collecte triangulaire, plusieurs ouvertures d'aspiration reliées entre elles par une structure sensiblement parallèle à la surface à traiter et reliée à un conduit d'évacuation par une connexion en T, perpendiculaire à la surface à traiter permettant au suceur de présenter une structure compacte, et de garder une bonne efficacité d'aspiration.Such a nozzle, thus presents a collection vein triangular, several suction openings connected between them by a structure substantially parallel to the surface to be treated and connected to an evacuation pipe by a T connection, perpendicular to the surface to be treated allowing the nozzle to present a compact structure, and keep good suction efficiency.

La structure en H, symétrique par rapport à la connexion d'évacuation en T, permet au suceur d'aspirer de façon identique de chaque côté du suceur, tout en permettant de collecter également les déchets par le canal postérieur.The H-shaped structure, symmetrical with respect to the drain connection in T, allows the nozzle to suck identical on each side of the squeegee, while also allowing waste to be collected via the channel posterior.

Avantageusement, ledit circuit de circulation d'air comporte une pluralité de déflecteurs destinés à éviter une collision frontale entre les flux d'air entrant par des ouvertures d'aspiration du suceur.Advantageously, said air circulation circuit comprises a plurality of deflectors intended to avoid a frontal collision between incoming air flows through suction nozzle openings.

Ces déflecteurs modifient les directions d'écoulement des flux d'air de telle sorte que ces derniers ne se rencontrent plus frontalement mais tangentiellement.These deflectors modify the directions flow of air flows so that these no longer meet head-on but tangentially.

Comme on peut le voir sur la figure 1, le suceur d'aspirateur comporte une semelle 4 destinée à se déplacer sur la surface à nettoyer, le rebord de ladite semelle présente une zone angulaire 6 munie d'une ouverture d'aspiration frontale 12 et dont l'extrémité est arrondie afin d'éviter de détériorer les murs et les meubles lors du déplacement du suceur. La face supérieure de la semelle est munie d'un circuit de circulation d'air 8 et sa face inférieure est munie de patins amovibles 10 permettant au suceur de glisser sur la surface à nettoyer.As can be seen in Figure 1, the squeegee vacuum cleaner has a sole 4 for moving on the surface to be cleaned, the edge of said sole has an angular zone 6 provided with an opening front suction 12 and whose end is rounded to avoid damaging the walls and furniture when displacement of the squeegee. The upper side of the sole is provided with an air circulation circuit 8 and its face lower is provided with removable pads 10 allowing the nozzle to slide on the surface to be cleaned.

Selon l'invention, la semelle 4 présente une forme sensiblement triangulaire dont les deux côtés adjacents 24 comportent chacun un canal latéral 26 ouvert vers la surface à nettoyer agencé le long du rebord de la semelle. Chacun desdits canaux 26 est relié au moyen d'un coude 28 ouvert vers la surface à nettoyer à un canal postérieur 27 agencé le long du troisième côté 30 formant la face postérieure de la semelle 4. Les canaux 26 et 27 forment ainsi une veine d'écoulement triangulaire plane et parallèle à la surface à nettoyer. Les coudes 28 sont sensiblement perpendiculaires audit côté 30 et comportent chacun au moins une ouverture latérale d'aspiration 13.According to the invention, the sole 4 has a shape substantially triangular with two adjacent sides 24 each have a side channel 26 open towards the surface to be cleaned arranged along the edge of the sole. Each of said channels 26 is connected by means of an elbow 28 open to the surface to be cleaned at a posterior canal 27 arranged along the third side 30 forming the face posterior of the sole 4. Channels 26 and 27 form thus a planar triangular flow vein and parallel to the surface to be cleaned. Elbows 28 are substantially perpendicular to said side 30 and have each at least one lateral suction opening 13.

Selon l'invention, les canaux 26,27 présentent une forme tubulaire et chacun des canaux 26 comporte une ouverture inférieure 14 tandis que le canal postérieur 27 comporte deux ouvertures inférieures 14 situées symétriquement par rapport au point milieu dudit côté postérieur 30. La figure 6 montre clairement que les quatre ouvertures 14 forment un rectangle virtuel d'aspiration.According to the invention, the channels 26, 27 have a tubular shape and each of the channels 26 has a lower opening 14 while the posterior channel 27 has two lower openings 14 located symmetrically with respect to the midpoint of said side posterior 30. Figure 6 clearly shows that the four openings 14 form a virtual suction rectangle.

Les ouvertures inférieures 14 sont destinées à assurer une aspiration des déchets dans une direction perpendiculaire à la surface à nettoyer.The lower openings 14 are intended for ensure waste suction in one direction perpendicular to the surface to be cleaned.

Une connexion en T 11, montée de façon amovible sur la face supérieure de ladite semelle 4, permet de relier, via ledit circuit de circulation d'air 8, les pluralités d'ouvertures d'aspiration 12,13,14 à un tube amovible 16 d'évacuation des déchets aspirés.A T 11 connection, removably mounted on the upper face of said sole 4 makes it possible to connect, via said air circulation circuit 8, the pluralities of suction openings 12,13,14 to a removable tube 16 evacuation of aspirated waste.

Comme on peut le voir sur les figures 1, 2, 3 et 6, le circuit de circulation d'air 8 présente une forme en H ayant une gorge centrale 40 dans laquelle est monté le conduit 42 constituant la barre horizontale de la connexion en T 11 et deux gorges latérales 44 reliant chacune des deux ouvertures inférieures 14 situées le long du côté postérieur 30 de la semelle 4 à l'une des deux ouvertures inférieures 14 situées le long de l'un des côtés latéraux 24.As you can see in Figures 1, 2, 3 and 6, the air circulation circuit 8 has an H shape having a central groove 40 in which the conduit 42 constituting the horizontal bar of the connection in T 11 and two lateral grooves 44 connecting each of the two lower openings 14 located along the side posterior 30 from sole 4 to one of the two openings lower 14 located along one of the lateral sides 24.

La connexion en T est située au centre du circuit de circulation d'air en forme de H, ce qui permet d'assurer une aspiration symétrique de part et d'autre du suceur. The T connection is located in the center of the circuit H-shaped air circulation, which ensures a symmetrical suction on either side of the nozzle.

Selon une variante de réalisation de la présente invention, la configuration des ouvertures 14, par leur taille et leur positionnement par rapport au conduit d'évacuation, est telle que la dépression créée sous chaque ouverture est sensiblement identique. En proposant des formes d'ouvertures voisines, un tel suceur présente alors une autre symétrie d'aspiration perpendiculaire à la première symétrie évoquée. Dès lors, les quatre ouvertures d'aspiration possèdent un rôle identique quant à leur pouvoir d'aspiration, la partie dite "postérieure" pouvant être utilisée également en tant que front du suceur sans occasionner de gêne pour l'utilisateur au niveau des surfaces réellement nettoyées. Un tel suceur présente ainsi une quasi-symétrie d'ordre 4 au niveau de l'aspiration.According to an alternative embodiment of the present invention, the configuration of the openings 14, by their size and positioning relative to the duct evacuation, is such that the depression created under each opening is substantially identical. By offering neighboring openings, such a nozzle then presents another suction symmetry perpendicular to the first symmetry mentioned. From then on, the four openings have an identical role in their suction power, the so-called "posterior" part being able to also be used as a squeegee front without cause discomfort for the user in terms of surfaces actually cleaned. Such a nozzle thus presents a quasi-symmetry of order 4 at the level of the aspiration.

En fonctionnement, les gorges latérales 44 du circuit de circulation d'air 8 sont couvertes à leurs extrémités par un premier couvercle 50 de forme plate et à leur milieu par un deuxième couvercle 52 de forme semi-cylindrique prolongeant le conduit 42 de la connexion en T 11. Afin de simplifier le schéma de la figure 2, ces couvercles 50, 52 ont été représentés uniquement sur la gorge latérale 44 gauche.In operation, the lateral grooves 44 of the air circulation circuit 8 are covered at their ends by a first cover 50 of flat shape and their middle by a second cover 52 of semi-cylindrical shape extending the duct 42 of the T-connection 11. In order to simplify the diagram in Figure 2, these covers 50, 52 have been shown only on the lateral groove 44 left.

Avantageusement, le circuit de circulation d'air 8 comporte une pluralité de déflecteurs 20 destinés à éviter une collision frontale entre les flux d'air entrant par les ouvertures 14.Advantageously, the air circulation circuit 8 comprises a plurality of deflectors 20 intended to avoid a frontal collision between the air flows entering through the openings 14.

Ainsi, comme on peut le voir sur la figure 1, chacune des gorges latérales 44 du circuit en H comporte un déflecteur latéral 20 situé à proximité de la zone de rencontre des flux d'air entrant par les ouvertures d'aspiration inférieures 14 situées l'une en face de l'autre. La connexion en T 11 comporte également, comme on peut le voir sur les figures 2 et 5, un déflecteur central 54 destiné à éviter une collision frontale entre les flux d'air circulant dans le conduit 42. So, as you can see in Figure 1, each of the lateral grooves 44 of the H-shaped circuit has a side deflector 20 located near the area of encounter air flows entering through the openings lower suction 14 located one opposite the other. The connection at T 11 also includes, as can see in Figures 2 and 5, a central deflector 54 intended to avoid a frontal collision between flows of air circulating in the duct 42.

Selon une autre caractéristique du suceur conforme à l'invention, la semelle 4 est reliée à la connexion en T 11 par une articulation 56 permettant d'assurer, d'une part, une rotation de 360° de la semelle 4 par rapport au tube 16.According to another characteristic of the conforming nozzle in the invention, the sole 4 is connected to the T-connection 11 by a hinge 56 making it possible, hand, a 360 ° rotation of the sole 4 relative to the tube 16.

L'articulation 56 comporte un élément de rotation, non représenté, composé du tube en T qui pivote lui-même de 180° dans le logement formé par la gorge centrale 40 autour d'un axe horizontal 58 confondu avec l'axe de symétrie du conduit 42 formant la barre horizontale de la connexion en T 11.The articulation 56 includes a rotation element, not shown, composed of the T-tube which pivots itself by 180 ° in the housing formed by the central groove 40 around of a horizontal axis 58 merged with the axis of symmetry of the conduit 42 forming the horizontal bar of the connection in T 11.

La figure 6 présente une variante de réalisation de la présente invention, où des trous 81 d'aspiration et /ou de mise en équi-pression sont situés au centre du suceur. Ces trous sont disposés de telle manière à former une zone supplémentaire d'aspiration située sous le suceur, délimitée de façon interne par les trois canaux d'aspiration 26 et 27, un de ces trous étant en communication avec l'air extérieur au suceur afin de permettre le passage de l'air. Cet air permet d'entraíner les poussières situées sous le suceur vers les canaux 26 et 27 ainsi que vers les canaux d'aspiration 14. L'efficacité de dépoussiérage est ainsi améliorée. De plus cette configuration permet de réduire la force exercée par le suceur sur le sol. Les paramètres géométriques des trous peuvent être réglés (nombre, diamètre, profil, emplacement...) afin d'ajuster l'efficacité de dépoussiérage ainsi que le déplacement du suceur. Ce dispositif est particulièrement adapté aux surfaces de type moquette.Figure 6 shows an alternative embodiment of the present invention, where suction holes 81 and / or equi-pressure are located in the center of the squeegee. These holes are arranged so as to form an area additional suction located under the squeegee, internally bounded by the three channels suction 26 and 27, one of these holes being in communication with the air outside the nozzle in order to allow the passage of air. This air allows to train the dust located under the squeegee towards the channels 26 and 27 as well as to the suction channels 14. Efficiency dedusting is thus improved. Furthermore this configuration reduces the force exerted by the crevice on the floor. The geometric parameters of the holes can be set (number, diameter, profile, location ...) in order to adjust the efficiency of dust removal as well as the displacement of the squeegee. This device is particularly suitable for surfaces of the type carpet.

Afin d'éviter les chocs entre le suceur et l'environnement d'utilisation de l'aspirateur, la semelle 4 est couverte sur sa face supérieure par un capot amovible 60 en matériau souple couvrant également les bords extérieurs des côtés 24 et 30 ainsi que les coudes 28 de ladite semelle 4. Ledit capot souple 60 comporte en son milieu un évidement permettant le passage de la connexion 11 pour assurer la fixation du tube 16. Notons que le capot 60 a essentiellement une fonction d'anti-choc dans la mesure où le circuit de circulation d'air 8 est totalement couvert par les couvercles (50, 52) et de ce fait le suceur peut aspirer les déchets même lorsque ce capot 60 est retiré.To avoid impacts between the squeegee and the environment in which the vacuum cleaner is used, the soleplate 4 is covered on its upper side by a removable cover 60 of flexible material also covering the edges sides 24 and 30 as well as the elbows 28 of said sole 4. Said flexible cover 60 comprises in its middle a recess allowing the passage of the connection 11 to secure the tube 16. Note that the cover 60 basically has an anti-shock function in the measure that the air circulation circuit 8 is completely covered by the covers (50, 52) and thereby the squeegee can suck up the waste even when this cover 60 is took of.

Afin d'assurer un déplacement par glissement du suceur sur des surfaces de différents types, les patins amovibles 10, représentés schématiquement à la figure 7, comportent une face inférieure 70, ayant un bord d'attaque arrondi 72, et sont munis d'une pastille centrale 74 assurant le contact avec la surface à nettoyer lors du déplacement de l'appareil. Ladite pastille centrale 74 peut être en polytétrafluoréthylène (PTFE) ou en tout autre matériau ayant une bonne résistance à l'abrasion et un faible coefficient de frottement.In order to ensure a sliding movement of the crevice on surfaces of different types, the pads removable 10, shown schematically in FIG. 7, have a lower face 70, having a leading edge rounded 72, and are provided with a central pad 74 ensuring contact with the surface to be cleaned during moving the device. Said central pad 74 can be made of polytetrafluoroethylene (PTFE) or any other material with good abrasion resistance and low coefficient of friction.

La face supérieure desdits patins 10 est munie d'une couronne centrale 78 entourée par un joint annulaire 80 destiné à absorber les vibrations lorsque le suceur se déplace sur une surface accidentée. Ces patins peuvent être fixés sur une partie 79 liée à la semelle 4 par des crochets 77.
