- the squeegee vacuum cleaner 2 has a soleplate 4 intended to move the rim parallel to the surface to be cleaned of said sole has an angular zone 6 connecting two sides of the squeegee and whose end is rounded so avoid damaging walls and furniture during cleaning.
- This angular area is advantageously set value in a triangular nozzle as described in the present request, as an example of implementation, but the invention can also be applied to a nozzle any shape, circular with a point which forms said angular zone, but also for a nozzle rectangular then having four angular zones of connection of the edges, located at the four corners of the squeegee.
- said angular zone comprises an orifice front 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
- Front opening means an opening starting from the sole, where the suction channel is located and extending over the edge of the squeegee.
- the opening is like this substantially perpendicular to the surface to be cleaned.
- This opening is large enough to be able to vacuum small objects.
- the size of the opening is greater than 0.5 cm 2 .

Abstract
Description
La présente invention concerne un suceur d'aspirateur comportant une semelle dont le rebord présente au moins une zone angulaire et plus particulièrement un suceur comportant une semelle destinée à se déplacer sur la surface à nettoyer ayant une face supérieure munie d'un circuit de circulation d'air et une face inférieure munie d'au moins deux patins amovibles permettant au suceur de glisser sur la surface à nettoyer. Une connexion en T, montée de façon amovible sur la face supérieure de la semelle, permet de relier via ledit circuit de circulation d'air, une pluralité d'orifices d'aspiration à un tube amovible d'évacuation des déchets aspirés.The present invention relates to a vacuum cleaner nozzle comprising a sole whose rim has at least one zone angular and more particularly a nozzle having a sole intended to move on the surface to be cleaned having an upper face provided with an air circulation circuit and a lower face provided with at least two removable pads allowing the nozzle to slide on the surface to be cleaned. A T-connection, removably mounted on the upper side of the sole, allows to connect via said circulation circuit air, a plurality of suction ports to a removable tube evacuation of aspirated waste.
L'invention concerne également un aspirateur comportant un tel suceur.The invention also relates to a vacuum cleaner comprising such a sucker.
Les suceurs pour aspirateur de l'art antérieur, présentent généralement des formes et des dimensions qui rendent leur utilisation malaisée particulièrement pour aspirer des déchets situés dans des coins ou des passages étroits ou pour aspirer des déchets qui se trouvent sur des surfaces encombrées par des meubles. Dans le premier cas, l'utilisateur est obligé de changer l'embout de l'aspirateur pour atteindre les coins ou les passages étroits, tandis que dans le deuxième cas, l'utilisateur est obligé de déplacer les meubles afin de positionner la semelle du suceur au dessus des déchets.The nozzles for vacuum cleaners of the prior art, generally have shapes and dimensions that make their awkward use particularly for vacuuming waste located in narrow corners or passages or for pick up waste from congested surfaces by furniture. In the first case, the user is obliged to change the nozzle of the vacuum cleaner to reach the corners or narrow passages, while in the second case, the user is obliged to move the furniture in order to position the squeegee soleplate above the waste.
Le document DE 18 15 059 décrit un suceur pour
aspirateur de forme générale rectangulaire possédant des
ouvertures frontales sur toute la longueur du suceur, ces
ouvertures se présentant sous la forme de petits canaux
d'écoulement. Ce suceur ne permet cependant pas d'aspirer des
déchets logés dans des endroits angulaires.
La demande internationale de brevet numéro WO84/03429 décrit un suceur pour aspirateur de forme triangulaire muni d'orifices d'aspiration latéraux situés en dessous d'une cavité d'aspiration et au milieu des côtés du triangle. Un tel suceur ne permet pas de résoudre le problème mentionné ci-dessus dans la mesure où, pour aspirer les déchets situés dans un coin ou un passage étroit, l'utilisateur doit d'abord positionner le suceur au dessus de ces déchets. Ceci n'est possible que si l'angle du coin est suffisamment large pour permettre de positionner la semelle du suceur sur les déchets. Dans le cas où cet angle est étroit, l'utilisateur est encore obligé de changer l'embout de l'aspirateur pour atteindre les déchets.International patent application number WO84 / 03429 describes a triangular vacuum nozzle provided side suction ports located below a cavity and in the middle of the sides of the triangle. Such a sucker does not solve the problem mentioned above in the extent that, to vacuum the waste located in a corner or a narrow passage, the user must first position the squeegee above this waste. This is only possible if the angle of the corner is wide enough to allow positioning the squeegee sole on the waste. In case this angle is narrow, the user is still obliged to change the tip of the vacuum cleaner to reach the waste.
Par le document US 4,653,137, est également connu un suceur d'aspirateur de forme triangulaire comportant deux canaux latéraux d'aspiration ouverts vers la surface à nettoyer, en liaison avec un tube d'évacuation. Dans la pointe du suceur, une ouverture en direction de la surface à nettoyer est créée. Cette ouverture peut être insérée dans le circuit d'aspiration selon la volonté de l'utilisateur, dans une configuration particulière de l'invention. Un tel dispositif est cependant peu pratique d'utilisation, l'ouverture étant d'une part masquée, puisque disposée entièrement sous le suceur, et d'autre part, pour les déchets volumineux, il nécessite de soulever le suceur afin de le positionner sur le déchet à aspirer.Document US 4,653,137 also discloses a triangular vacuum nozzle with two channels suction side open to the surface to be cleaned, in connection with an evacuation tube. In the nozzle tip, a opening towards the surface to be cleaned is created. This opening can be inserted in the suction circuit according to the will of the user, in a particular configuration of the invention. Such a device is however impractical of use, the opening being partly hidden, since arranged entirely under the squeegee, and on the other hand, for bulky waste, it requires lifting the squeegee in order to position it on the waste to be vacuumed.
Le but de l'invention est de pallier aux inconvénients mentionnés ci-dessus au moyen d'un suceur d'aspirateur comportant une semelle dont le rebord présente au moins une pointe qui forme une zone angulaire reliant deux bords adjacents quelconques du suceur, caractérisé en ce que ladite zone angulaire comporte au moins un orifice destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer.The object of the invention is to overcome the drawbacks mentioned above by means of a vacuum cleaner nozzle comprising a sole whose rim has at least one point which forms an angular zone connecting two adjacent edges any of the nozzle, characterized in that said zone angular comprises at least one orifice intended to ensure a suction in a direction substantially parallel to the surface to be cleaned.
Un tel suceur permet d'approcher une ouverture d'aspiration le plus possible des déchets situés dans des coins ou des passages étroits.Such a nozzle makes it possible to approach an opening as much as possible of the waste located in corners or narrow passages.
Grâce à cet orifice, le suceur est capable d'aspirer à distance les déchets situés dans les coins ou les passages étroits même si la semelle dudit suceur n'est pas positionnée au dessus de ces déchets.Thanks to this orifice, the squeegee is able to aspirate distance the waste located in corners or passages narrow even if the sole of said nozzle is not positioned at the above this waste.

Comme on peut le voir sur la figure 2, le suceur
d'aspirateur 2 comporte une semelle 4 destinée à se
déplacer parallèlement à la surface à nettoyer, le rebord
de ladite semelle présente une zone angulaire 6 reliant
deux côtés du suceur et dont l'extrémité est arrondie afin
d'éviter de détériorer les murs et les meubles pendant le
nettoyage. Cette zone angulaire est avantageusement mise en
valeur dans un suceur triangulaire tel que décrit dans la
présente demande, à titre d'exemple de réalisation, mais
l'invention peut également être appliquée à un suceur de
forme quelconque, circulaire en présentant une pointe qui
forme ladite zone angulaire, mais aussi pour un suceur
rectangulaire possédant alors quatre zones angulaires de
liaison des bords, situés aux quatre coins du suceur.As can be seen in Figure 2, the
Selon une caractéristique importante de l'invention, ladite zone angulaire comporte un orifice frontal 7 destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer. According to an important characteristic of the invention, said angular zone comprises an orifice front 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
Par orifice frontal, il faut entendre une ouverture partant de la semelle, où est situé le canal d'aspiration et s'étendant sur le bord du suceur. L'ouverture est ainsi sensiblement perpendiculaire à la surface à nettoyer.Front opening means an opening starting from the sole, where the suction channel is located and extending over the edge of the squeegee. The opening is like this substantially perpendicular to the surface to be cleaned.
Cette ouverture est de taille suffisante pour pouvoir aspirer de petits objets. Ainsi la taille de l'ouverture est supérieure à 0,5 cm2.This opening is large enough to be able to vacuum small objects. Thus the size of the opening is greater than 0.5 cm 2 .
Avantageusement, afin de ne pas créer une perte d'aspiration au niveau du sol, l'ouverture est profilée en présentant un angle de fuite à la base de telle sorte que la largeur de l'ouverture à sa base soit au moins deux fois plus importante que sa largeur à mi-hauteur.Advantageously, in order not to create a loss suction at ground level, the opening is profiled in exhibiting a leak angle at the base such that the width of the opening at its base is at least twice more important than its width at half height.
La figure 8 montre une telle ouverture 72
présentant un angle de fuite 74. La largeur ℓ1 à sa base
est au moins deux fois plus importante que sa largeur ℓ2 à
mi-hauteur.Figure 8 shows such an opening 72
having a
Comme on peut le voir sur les figures 3, 5 et 6, la
face supérieure de ladite semelle 4, est munie d'un circuit
de circulation d'air 8 tandis que sa face inférieure
comporte trois patins de glissement amovibles 9 permettant
le déplacement du suceur sur la surface à nettoyer. Une
connexion en T 10, montée de façon amovible sur la face
supérieure de la semelle 4, permet de relier, via ledit
circuit de circulation d'air 8, une pluralité d'orifices
d'aspiration 7,11,14 à un tube amovible 16 d'évacuation des
déchets aspirés.As can be seen in Figures 3, 5 and 6, the
upper face of said sole 4, is provided with a
Selon un mode préféré de réalisation de
l'invention, la semelle 4 présente une forme sensiblement
triangulaire dont les deux côtés adjacents 18 comportent
chacun un canal latéral 19 ouvert vers la surface à
nettoyer agencé le long du rebord de la semelle 4. According to a preferred embodiment of
the invention, the sole 4 has a shape substantially
triangular whose two
Selon une variante de réalisation, conforme à
l'exemple proposé à titre d'illustration de l'invention,
chacun des canaux latéraux 19 est relié à un canal
postérieur 20 agencé le long du troisième côté 21 formant
la face postérieure de la semelle 4, au moyen d'un coude 22
ouvert vers la surface à nettoyer sensiblement
perpendiculaire audit côté 21 et comportant au moins un
orifice latéral d'aspiration 11.According to an alternative embodiment, in accordance with
the example proposed by way of illustration of the invention,
each of the
En outre, comme on peut le voir sur la figure 4,
les canaux latéraux 19 communiquent avec un orifice
inférieur 14 tandis que le canal postérieur 20 communique
avec deux orifices inférieurs 14 situés symétriquement par
rapport au milieu dudit côté postérieur 21. Ces orifices
inférieurs 14 sont destinés à assurer une aspiration des
déchets dans une direction perpendiculaire à la surface à
nettoyer.Furthermore, as can be seen in Figure 4,
the
Comme on peut le voir sur les figures 3, 5 et 6, le
circuit de circulation d'air 8 présente une forme en H
ayant une gorge centrale 32 dans laquelle est monté le
conduit 34 constituant la barre horizontale de la connexion
en T 10 et deux gorges latérales 38 reliant chacun des deux
orifices inférieurs 14 situés sur le canal postérieur 20 à
l'un des deux orifices inférieurs 14 situés sur l'un des
canaux latéraux 19 et au conduit 34. Les gorges latérales
38 du circuit de circulation d'air 8 sont couvertes à leurs
extrémités par un premier couvercle 40 de forme plate et à
leur milieu par un deuxième couvercle de forme semi-cylindrique
42 prolongeant le conduit 34 de la connexion en
T 10.As can be seen in Figures 3, 5 and 6, the
Comme on peut le voir sur la figure 6, chacune des
gorges latérales 38 du circuit en H comporte un déflecteur
latéral 50 situé à proximité de la zone de rencontre des
flux d'air entrant par les orifices inférieurs d'aspiration
14 situés l'un en face de l'autre. La connexion 10 comporte
également, comme on peut le voir sur les figures 4 et 6,
deux déflecteurs centraux 52 destinés à éviter une
collision frontale entre les flux d'air circulant dans le
conduit 34.As can be seen in Figure 6, each of the
Afin d'éviter les chocs entre le suceur et
l'environnement lors de l'utilisation de l'aspirateur, la
semelle 4, comme cela est illustré aux figures 2 et 4, est
couverte sur sa face supérieure par un capot 54 en matériau
souple couvrant également les bords extérieurs des côtés 18
et 21 ainsi que les coudes 22 de ladite semelle 4. Ledit
capot souple 54 comporte en son milieu un trou permettant
le passage de la connexion 10 pour assurer la fixation du
tube 16. Notons que le capot 54 a essentiellement une
fonction d'anti-choc dans la mesure où le circuit de
circulation d'air 8 est totalement couvert par les
couvercles 40, 42 et de ce fait le suceur peut aspirer les
déchets même lorsque ce capot 54 est retiré de la face
supérieure de la semelle.To avoid impacts between the squeegee and
the environment when using the vacuum cleaner, the
sole 4, as illustrated in FIGS. 2 and 4, is
covered on its upper face by a
Afin d'assurer un déplacement du suceur sur des
surfaces de différents types, les patins amovibles 9,
représentés schématiquement aux figures 4 et 7, comportent
une surface inférieure 60, ayant un bord d'attaque profilé
62, et sont munis d'une pastille centrale 64 assurant le
contact avec la surface à traiter lors du déplacement de
l'appareil. Ladite pastille centrale 64 peut être en PTFE
(polytétrafluoréthylène) ou en tout autre matériau ayant
une bonne résistance à l'abrasion et un faible coefficient
de frottement. La face supérieure 66 desdits patins 9 est
munie d'une couronne centrale 68 entourée par un joint
annulaire 70 destiné à absorber les vibrations lorsque le
suceur se déplace sur une surface accidentée.In order to ensure displacement of the squeegee on
surfaces of different types, the
Avantageusement, les patins de glissement sont
agencés à la semelle de telle sorte à surélever le suceur
de la surface à nettoyer. La distance séparant le suceur du
sol, que l'on peut assimiler à une garde au sol, par
analogie avec le domaine automobile, permet d'établir une
synergie entre une aspiration grossière par la ou les
ouvertures 7, 11 et une aspiration fine par les côtés du
suceur.Advantageously, the sliding pads are
arranged in the sole so as to raise the squeegee
of the surface to be cleaned. The distance between the squeegee and the
ground, which can be compared to ground clearance, for
analogy with the automotive field, allows to establish a
synergy between coarse aspiration by the
Ceci permet également d'établir un bon compromis entre la facilité pour déplacer le suceur au sol, grâce à la fuite d'air créée, et la dépression d'aspiration.This also makes it possible to establish a good compromise between the ease of moving the nozzle on the ground, thanks to the air leak created, and the suction depression.
L'invention trouve son application dans le domaine des aspirateurs ménagers.The invention finds its application in the field household vacuum cleaners.
