Description

La présente invention concerne de manière générale un suceur d'aspirateur muni d'une trappe d'accès à une brosse motorisée.The present invention relates generally to a vacuum cleaner nozzle provided with a hatch for access to a motorized brush.

Jusqu'ici, il est connu dans l'art antérieur des suceurs d'aspirateur, comme par exemple celui décrit dans le document FR 11 58711 , où le suceur divulgué comprend une semelle inférieure qui comporte au moins un canal d'aspiration ouvert vers le sol et qui converge d'un rebord extérieur de la semelle vers un orifice d'aspiration relié à l'aspirateur. Le suceur divulgué est triangulaire et dans une variante celui-ci peut comprendre une brosse motorisée. Cependant ce système présente l'inconvénient de n'avoir aucun élément de protection de la brosse motorisée qui est ainsi directement au contact du sol. Dans ce cas de figure, on constate que lorsque le suceur est utilisé dans des configurations particulières il se peut que la brosse motorisée soit endommagée lorsque un élément vient en contact avec l'arbre de rotation de la brosse.Until now, vacuum cleaner nozzles, such as that described in document FR 11 58711 , where the disclosed nozzle comprises a lower sole which comprises at least one suction channel open towards the ground and which converges from an outer rim of the sole towards a suction port connected to the vacuum cleaner. The disclosed nozzle is triangular and in a variant this may comprise a motorized brush. However, this system has the drawback of having no protective element for the motorized brush which is thus directly in contact with the ground. In this case, it is observed that when the nozzle is used in particular configurations, it is possible that the motorized brush is damaged when an element comes into contact with the rotation shaft of the brush.

Le document GB2413942 présente quant à lui un suceur muni d'une trappe d'accès à une brosse motorisée. La brosse motorisée s'insère derrière cette trappe et lors d'une utilisation du suceur, la trappe permet dans une certaine mesure de protéger la brosse motorisée. L'avantage d'une telle structure est que l'arbre de cette brosse est protégé par la trappe et le risque de dégradation est limité. Cependant l'inconvénient d'un tel système est que les qualités d'aspiration du suceur sont dégradées au profit de la sécurité de la brosse motorisée. En effet dans ce document la semelle de la trappe est sensiblement plate ce qui implique que tout l'air aspiré l'est par l'orifice d'aspiration intégré dans la trappe. Dans ce cas là, il n'y a pas de maitrise des vitesses d'air vers l'intérieur du suceur.The document GB2413942 presents a nozzle fitted with a hatch for access to a motorized brush. The motorized brush is inserted behind this hatch and when using the squeegee, the hatch allows to a certain extent to protect the motorized brush. The advantage of such a structure is that the shaft of this brush is protected by the hatch and the risk of degradation is limited. However, the drawback of such a system is that the suction qualities of the nozzle are degraded in favor of the safety of the motorized brush. In fact, in this document, the sole of the hatch is substantially flat, which implies that all the air sucked in is through the suction port integrated in the hatch. In this case, there is no control of the air speeds towards the inside of the squeegee.

DE202009017029 divulgue un suceur d'aspirateur d'après le préambule de la revendication 1. US 2003/182752 divulgue un suceur d'aspirateur avec une brosse motorisée et une trappe amovible fixée par des clips. DE202009017029 discloses a vacuum cleaner nozzle according to the preamble of claim 1. US 2003/182752 discloses a vacuum cleaner nozzle with a motorized brush and a removable hatch fixed by clips.

Un but de la présente invention est de répondre aux inconvénients des documents de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un suceur d'aspirateur dans lequel une brosse motorisée amovible est protégée et accessible à un utilisateur et ceci sans que les qualités d'aspiration ne soient dégradées.An aim of the present invention is to respond to the drawbacks of the documents of the prior art mentioned above and in particular, all first, to provide a vacuum cleaner nozzle in which a removable motorized brush is protected and accessible to a user and this without the suction qualities being degraded.

Pour cela un premier aspect de l'invention concerne un suceur d'aspirateur qui comprend une semelle. La semelle comporte au moins un canal d'aspiration ouvert vers le sol et le canal d'aspiration converge d'un rebord extérieur de la semelle vers un orifice d'aspiration en liaison aéraulique avec un aspirateur. Selon l'invention, la semelle comprend une trappe amovible d'accès à une brosse motorisée qui comporte d'une part l'orifice d'aspiration et d'autre part au moins un canal d'aspiration ouvert vers le sol et agencé en vis-à-vis dudit au moins un canal d'aspiration de la semelle. De cette manière, un utilisateur peut enlever la trappe du suceur et la remettre et les canaux ainsi formés par l'association des canaux de la semelle et de la trappe définissent un chemin pour le flux d'air qui se dirige vers l'orifice d'aspiration. De cette manière, l'efficacité d'aspiration ne se trouve pas atténuée et les poussières restent aspirées de façon efficace.For this, a first aspect of the invention relates to a vacuum cleaner nozzle which comprises a sole. The sole comprises at least one suction channel open towards the ground and the suction channel converges from an outer rim of the sole towards a suction orifice in aeraulic connection with a vacuum cleaner. According to the invention, the sole comprises a removable hatch for access to a motorized brush which comprises on the one hand the suction orifice and on the other hand at least one suction channel open towards the ground and arranged as a screw. -à-vis-à-vis said at least one suction channel of the sole. In this way, a user can remove the squeegee hatch and put it back and the channels thus formed by the association of the channels of the sole and the hatch define a path for the air flow which goes to the orifice of the squeegee. aspiration. In this way, the suction efficiency is not reduced and the dust remains sucked up effectively.

De manière avantageuse, le suceur d'aspirateur comprend une cavité ouverte vers le sol, et la trappe est agencée sur la cavité, ce qui signifie que la trappe peut recouvrir au moins partiellement la cavité.Advantageously, the vacuum cleaner nozzle comprises a cavity open towards the ground, and the hatch is arranged on the cavity, which means that the hatch can at least partially cover the cavity.

Une réalisation particulièrement intéressante consiste en ce que la trappe recouvre intégralement ladite cavité. Dans ce cas de figure, la superficie de la trappe est égale à la superficie de la cavité qui est dirigée vers le sol. Avantageusement, la trappe du suceur d'aspirateur comprend un dispositif d'accroche pour maintenir ladite trappe sur la semelle.A particularly interesting embodiment consists in that the hatch completely covers said cavity. In this case, the area of the trap door is equal to the area of the cavity which is directed towards the ground. Advantageously, the hatch of the vacuum cleaner nozzle comprises a hooking device for maintaining said hatch on the sole.

Avantageusement, le dispositif d'accroche de la trappe est un système de clips. Ce dispositif d'accroche présente l'intérêt de manipuler la trappe rapidement. L'utilisateur peut ainsi enlever rapidement la trappe afin d'accéder à la cavité, soit la remettre rapidement pour isoler la cavité.Advantageously, the device for attaching the hatch is a system of clips. This hooking device has the advantage of handling the hatch quickly. The user can thus quickly remove the hatch in order to access the cavity, or replace it quickly to isolate the cavity.

Selon l'invention, le suceur d'aspirateur est sensiblement triangulaire avec une pointe dirigée dans le sens de déplacement du suceur. Lorsqu'un utilisateur manipule le suceur, il peut le déplacer dans toutes les directions du sol mais il existe une direction privilégiée de déplacement qui est en général celle donnée par l'architecture des roues. Dans le cadre de l'invention, le sens de déplacement privilégié est donné par la bissectrice du triangle formé par le suceur. De cette manière, la pointe du suceur est dirigée dans le sens de déplacement du suceur.According to the invention, the vacuum cleaner nozzle is substantially triangular with a point directed in the direction of movement of the squeegee. When a user manipulates the squeegee, he can move it in all directions of the ground, but there is a preferred direction of movement which is generally that given by the architecture of the wheels. In the context of the invention, the preferred direction of movement is given by the bisector of the triangle formed by the nozzle. In this way, the tip of the squeegee is directed in the direction of movement of the squeegee.

Avantageusement, l'axe longitudinal de la trappe est sensiblement perpendiculaire au sens de déplacement du suceur.Advantageously, the longitudinal axis of the hatch is substantially perpendicular to the direction of movement of the nozzle.

Avantageusement, le suceur d'aspirateur comprend une brosse motorisée amovible. Cette brosse motorisée peut être retirée par un utilisateur pour des besoins de maintenance de changement de la brosse ou bien même de nettoyage de celle-ci. Selon diverses variantes de réalisation, cette brosse peut avoir différentes formes et différents moyens de rotation.Advantageously, the vacuum cleaner nozzle comprises a removable motorized brush. This motorized brush can be removed by a user for maintenance needs of changing the brush or even cleaning it. According to various variant embodiments, this brush can have different shapes and different means of rotation.

Avantageusement, le suceur d'aspirateur comporte des roues qui définissent une garde au sol de la semelle. En d'autres termes, le suceur, et donc la semelle inférieure du suceur, est positionné à une hauteur prédéterminée du sol par les roues. Des roulettes sont rajoutées sous le suceur au niveau de la semelle.Advantageously, the vacuum cleaner nozzle comprises wheels which define a ground clearance for the sole. In other words, the squeegee, and therefore the lower sole of the squeegee, is positioned at a predetermined height from the ground by the wheels. Wheels are added under the nozzle at the level of the sole.

Un second aspect de l'invention est un aspirateur comportant au moins un suceur selon le premier aspect de l'invention.A second aspect of the invention is a vacuum cleaner comprising at least one nozzle according to the first aspect of the invention.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels :

  • la figure 1 représente un suceur selon l'invention vu en perspective de dessus ;
  • la figure 2 représente le suceur de la figure 1 vu de dessous;
  • la figure 3 représente une vue en perspective et de dessous du suceur d'aspirateur;
  • la figure 4 représente une vue de dessous en perspective et éclatée du suceur.
Other characteristics and advantages of the present invention will emerge more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which:
  • the figure 1 shows a nozzle according to the invention seen in perspective from above;
  • the figure 2 represents the sucker of the figure 1 seen from below;
  • the figure 3 shows a perspective and bottom view of the vacuum cleaner nozzle;
  • the figure 4 shows a bottom perspective and exploded view of the nozzle.

La figure 1 représente un suceur 1 d'aspirateur qui comporte une semelle 14 et des roues 2 dont le profil d'une bande de roulement 15 est en forme de tonneau et qui définit une garde au sol de la semelle 14 lorsque le suceur 1 repose sur un sol lisse. Au moins deux roulettes 3 sont également disposées sous la semelle 14. Le suceur 1 est en forme générale de triangle et une pointe 30 du triangle est positionnée dans le sens de déplacement du suceur 1.The figure 1 shows a vacuum cleaner nozzle 1 which comprises a sole 14 and wheels 2 whose profile of a tread 15 is barrel-shaped and which defines a ground clearance of the sole 14 when the nozzle 1 rests on a ground smooth. At least two rollers 3 are also arranged under the sole 14. The nozzle 1 is generally in the shape of a triangle and a point 30 of the triangle is positioned in the direction of movement of the nozzle 1.

Dans un certain mode de réalisation, on dispose autour de la semelle 14 une lèvre d'étanchéité ou bavette d'étanchéité 4. Cette bavette d'étanchéité 4 supprime les fuites entre le sol lisse et la semelle 14, et pour avoir une bonne efficacité d'aspiration, la bavette d'étanchéité 4 est ajourée en regard des canaux 10 de la semelle 14, de sorte que l'air aspiré sous la semelle 14 ne peut qu'entrer directement dans les canaux 10 de la semelle 14. Il en résulte une bonne aspiration des impuretés du sol car les vitesses d'air dans les canaux 10 de la semelle 14 sont maximales, puisque tout l'air aspiré y passe.In a certain embodiment, a sealing lip or sealing flap 4 is arranged around the sole 14. This sealing flap 4 eliminates leaks between the smooth ground and the sole 14, and in order to have good efficiency. suction, the sealing flap 4 is perforated facing the channels 10 of the sole 14, so that the air sucked under the sole 14 can only enter directly into the channels 10 of the sole 14. It The result is good suction of impurities from the ground because the air speeds in the channels 10 of the sole 14 are maximum, since all the air sucked up passes through them.

Les roues 2 positionnent en hauteur le suceur 1 par rapport au sol. La bavette d'étanchéité 4 rase le sol, de sorte à supprimer les fuites d'air entre le sol et la semelle 14, et des ouvertures 5 de la bavette d'étanchéité 4 agencées directement en face des canaux 10 laissent passer l'air dans ceux-ci pour entraîner les impuretés reposant sur le sol.The wheels 2 position the squeegee 1 in height relative to the ground. The sealing flap 4 skims the ground, so as to suppress air leaks between the ground and the sole 14, and openings 5 of the sealing flap 4 arranged directly opposite the channels 10 allow air to pass. in these to drive away the impurities resting on the soil.

La figure 2 permet de visualiser la semelle 14 sur laquelle il y a une pluralité de canaux 10 d'aspiration ouverts vers le sol et les canaux 10 d'aspiration convergent d'un rebord extérieur de la semelle 14 vers un orifice 9 d'aspiration en liaison aéraulique avec un aspirateur (non représenté). On entend par liaison aéraulique que le flux d'air qui converge dans l'orifice 9 d'aspiration est ensuite aspiré à travers un flexible (non représenté) relié au système d'aspiration et de filtrage de l'aspirateur. Dans le cas de l'invention, au moins un des canaux 10 débouche dans la pointe 30 du suceur 1.The figure 2 allows to visualize the sole 14 on which there is a plurality of suction channels 10 open towards the ground and the suction channels 10 converge from an outer rim of the sole 14 towards a suction orifice 9 in aeraulic connection with a vacuum cleaner (not shown). By air connection is meant that the air flow which converges in the orifice 9 suction is then sucked through a hose (not shown) connected to the suction and filtering system of the vacuum cleaner. In the case of the invention, at least one of the channels 10 opens into the tip 30 of the nozzle 1.

Dans le cadre de l'invention, le suceur 1 comprend une trappe 13 qui se trouve sensiblement dans le même plan que la semelle 14. Cette trappe 13 comporte l'orifice 9 d'aspiration et des canaux 20 d'aspiration ouverts vers le sol. Ces canaux 20 d'aspiration sont agencés en vis-à-vis des canaux 10 d'aspiration de la semelle 14 afin de maintenir le flux d'aspiration. En d'autres termes les canaux 20 de la trappe 13 et les canaux 10 de la semelle 14 ont leurs parties accolées qui ont sensiblement un profil similaire. Dans le cas visible sur la figure 2, en plus d'avoir leurs parties accolées sensiblement similaires, les canaux 20 de la trappe 13 et les canaux 10 de la semelle 14 ont sensiblement le même diamètre sur l'ensemble de leur longueur. Ceci a pour but de créer un canal de passage régulier qui permet au flux d'air traversant de ne pas connaitre de variation brutale de son débit. Ainsi de l'extrémité extérieure des canaux 10 de la semelle 14 jusqu'à l'extrémité intérieur des canaux 20 de la trappe 13 au niveau de l'orifice 9 d'aspiration, la variation de diamètre ne varie pas de plus de 5 pourcent. Grâce à ce dispositif, la qualité de l'aspiration est maintenue.In the context of the invention, the squeegee 1 comprises a hatch 13 which is located substantially in the same plane as the sole 14. This hatch 13 comprises the suction orifice 9 and suction channels 20 open towards the ground. . These suction channels 20 are arranged opposite the suction channels 10 of the sole 14 in order to maintain the suction flow. In other words, the channels 20 of the hatch 13 and the channels 10 of the sole 14 have their contiguous parts which have substantially a similar profile. In the case visible on the figure 2 , in addition to having their substantially similar contiguous parts, the channels 20 of the hatch 13 and the channels 10 of the sole 14 have substantially the same diameter over their entire length. The purpose of this is to create a regular passage channel which allows the flow of air passing through not to experience any sudden variation in its flow rate. Thus from the outer end of the channels 10 of the sole 14 to the inner end of the channels 20 of the hatch 13 at the level of the suction orifice 9, the variation in diameter does not vary by more than 5 percent. . Thanks to this device, the quality of the suction is maintained.

Comme cela est visible sur la figure 3, cette trappe 13 est amovible et peut être retirée de la semelle 14. Cette trappe 13 est sensiblement rectangulaire et comprend un dispositif d'accroche. Dans le cas présent, ce dispositif d'accroche est constitué de clips mécaniques constitués d'une part d'ergots 7 et d'autre part de gorges 6. Un tel dispositif permet à un utilisateur de retirer cette trappe 13 sans l'aide d'outils de manutention tels que par exemple des tournevis ou des clefs mâles à six pans. Un tel dispositif présente donc l'avantage de retirer rapidement la trappe 13. Pour procéder, l'utilisateur effectue une simple pression mécanique au niveau des ergots 7 ce qui a pour effet de libérer ceux-ci des gorges 6 de maintien et ainsi de pouvoir enlever la trappe 13. L'opération inverse est également rapide puisqu'il suffit à l'utilisateur de glisser les ergots 7 dans les gorges 6 prévues à cet effet et d'appliquer ensuite une faible pression sur la trappe 13 au niveau de ces ergots 7 pour que la trappe 13 reste maintenue par ces clips.As can be seen on the figure 3 , this hatch 13 is removable and can be removed from the sole 14. This hatch 13 is substantially rectangular and comprises a hooking device. In the present case, this hooking device consists of mechanical clips made up on the one hand of lugs 7 and on the other hand of grooves 6. Such a device allows a user to remove this hatch 13 without the aid of handling tools such as for example screwdrivers or Allen keys. Such a device therefore has the advantage of rapidly removing the hatch 13. To proceed, the user simply presses mechanically at the level of the lugs 7 which has the effect of releasing them from the retaining grooves 6 and thus of being able to. remove the hatch 13. The reverse operation is also rapid since it suffices for the user to slide the lugs 7 into the grooves 6 provided for this purpose and then apply a slight pressure on the flap 13 at the level of these lugs 7 so that the flap 13 remains held by these clips.

Lorsque l'utilisateur libère la trappe 13 du suceur 1, il peut accéder à une cavité 21 qui se trouve derrière cette trappe 13 et dans le suceur 1. Dans le cadre de l'invention, cette cavité 21 a sensiblement la forme d'un parallépipède rectangle et a son axe longitudinal qui est sensiblement perpendiculaire au sens de déplacement du suceur 1. L'axe longitudinal de la trappe 13 correspond à l'axe qui part d'une extrémité à l'autre de la trappe 13 et qui s'étend dans le sens de la longueur. Le sens de déplacement du suceur 1 représente le sens dans lequel un utilisateur utilise le suceur 1 dans un mode d'utilisation normal sur un sol. Ainsi comme cela a été précédemment évoqué, la pointe 30 du suceur 1 triangulaire se trouve orientée dans le sens de déplacement du suceur 1 lorsqu'il est utilisé dans un mode d'utilisation normal.When the user releases the hatch 13 of the squeegee 1, he can access a cavity 21 which is located behind this hatch 13 and in the squeegee 1. In the context of the invention, this cavity 21 has substantially the shape of a rectangular parallelepiped and has its longitudinal axis which is substantially perpendicular to the direction of movement of the nozzle 1. The longitudinal axis of the hatch 13 corresponds to the axis which starts from one end of the hatch 13 and which s' extends lengthwise. The direction of movement of the nozzle 1 represents the direction in which a user uses the nozzle 1 in a normal mode of use on a floor. Thus, as was previously mentioned, the tip 30 of the triangular nozzle 1 is oriented in the direction of movement of the nozzle 1 when it is used in a normal mode of use.

Une brosse 8 est visible sur la figure 4 et dans le cadre de l'invention, cette brosse 8 est motorisée et est amovible. Cette brosse vient s'insérer dans la cavité 21 et est maintenue dans celle-ci par un dispositif d'accroche. Ce dispositif d'accroche peut être de différents types et dans le cadre de l'invention il est constitué d'une part, et sur un premier côté de la brosse, d'une rainure 12 et d'autre part, et de l'autre côté de la brosse, d'un système à baïonnette 11. Ce système à baïonnette 11 permet de mettre en rotation la brosse 8 lorsque le système de mise en rotation de la brosse (non visible) est actif.A brush 8 is visible on the figure 4 and in the context of the invention, this brush 8 is motorized and is removable. This brush is inserted into the cavity 21 and is held there by a hooking device. This hooking device can be of different types and in the context of the invention it consists on the one hand, and on a first side of the brush, of a groove 12 and on the other hand, and of the on the other side of the brush, a bayonet system 11. This bayonet system 11 makes it possible to set the brush 8 in rotation when the system for setting the brush in rotation (not visible) is active.

Ainsi dans un mode d'utilisation de l'invention, l'aspirateur crée un flux d'air qui est aspiré dans les canaux 10 vers l'orifice 9 d'aspiration. Dans le cas ou le suceur 1 comprend la brosse 8 motorisée protégée par la trappe 13 telle que cela a été décrit précédemment, le flux d'air passe d'abord par les canaux 10 puis les canaux 20 pour arriver dans l'orifice 9 d'aspiration. L'ajout d'une trappe 13 protectrice de la brosse 8 permet grâce aux canaux 20 de la trappe 13 de conserver un flux d'aspiration constant et de ne pas diminuer la qualité d'aspiration.Thus in one mode of use of the invention, the vacuum cleaner creates an air flow which is sucked in the channels 10 towards the suction orifice 9. In the case where the nozzle 1 comprises the motorized brush 8 protected by the hatch 13 as described above, the air flow first passes through the channels 10 then the channels 20 to arrive in the orifice 9 d aspiration. The addition of a protective hatch 13 for the brush 8 allows, thanks to the channels 20 of the hatch 13, to maintain a constant suction flow and not to reduce the quality. suction.
