Description

TRAPPE DE SUCEUR D'ASPIRATEUR  VACUUM CLEANER TRAP
La présente invention concerne de manière générale un suceur d'aspirateur muni d'une trappe d'accès à une brosse motorisée. Jusqu'ici, il est connu dans l'art antérieur des suceurs d'aspirateur, comme par exemple celui décrit dans le document FR 1 1 5871 1 , 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. The present invention generally relates to a vacuum nozzle with a hatch access to a motorized brush. Heretofore, it is known in the prior art vacuum suction nozzles, such as that described in the document FR 1 1 5871 1, wherein the disclosed nozzle comprises a bottom flange which comprises at least one open suction channel towards the ground and which converges from an outer edge of the sole to a suction port connected to the vacuum cleaner. The disclosed nozzle is triangular and in a variant it may include a motorized brush. However, this system has the disadvantage of having no protection element of the motorized brush which is thus directly in contact with the ground. In this case, it is found that when the nozzle is used in particular configurations it may be that the motorized brush is damaged when an element comes into contact with the rotating 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 maîtrise des vitesses d'air vers l'intérieur du suceur. The document GB2413942 has meanwhile a nozzle with a hatch access to a motorized brush. The motorized brush fits behind this hatch and when using the nozzle, the hatch allows to some 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 disadvantage of such a system is that the suction qualities of the nozzle are degraded in favor of the safety of the motorized brush. Indeed in this document the flange of the hatch is substantially flat which implies that all the air is sucked by the suction port integrated in the hatch. In this case, there is no control of the air velocities towards the inside of the nozzle.
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 object of the present invention is to meet the disadvantages of the documents of the prior art mentioned above and in particular, all firstly, to propose a suction nozzle in which a removable motorized brush is protected and accessible to a user and this without the suction qualities are 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 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 which comprises a sole. The soleplate has at least one suction channel open to the ground and the suction channel converges from an outer edge of the soleplate to a suction port in aeraulic connection with a vacuum cleaner. According to the invention, the sole comprises a removable hatch which comprises on the one hand the suction port and on the other hand at least one suction channel open towards the ground and arranged vis-à-vis said at least a suction channel of the sole. In this way, a user can remove the squeegee door 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 flow of air that goes to the orifice of suction. In this way, the suction efficiency is not attenuated and the dust remains sucked 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. 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. Advantageously, the vacuum nozzle comprises a cavity open towards the ground, and the hatch is arranged on the cavity, which means that the hatch can cover at least partially the cavity. A particularly interesting embodiment consists in that the trap completely covers said cavity. In this case, the area of the hatch is equal to the area of the cavity which is directed towards the ground.
Avantageusement, la trappe du suceur d'aspirateur comprend un dispositif d'accroché pour maintenir ladite trappe sur la semelle. Avantageusement, le dispositif d'accroché de la trappe est un système de clips. Ce dispositif d'accroché 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 hatch of the vacuum cleaner comprises a hooking device for holding said hatch on the soleplate. Advantageously, the hooked device of the hatch is a system of clips. This hanging device has the advantage of handling the hatch quickly. The user can quickly remove the hatch to access the cavity, or quickly put it back 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 suction nozzle is substantially triangular with a point directed in the direction of displacement of the nozzle. When a user manipulates the nozzle, it can move it in all the directions of the ground but there is a preferred direction of displacement which is in general 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 nozzle is directed in the direction of movement of the nozzle.
Avantageusement, l'axe longitudinal de la trappe est sensiblement perpendiculaire au sens de déplacement du suceur. 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. 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. Un second aspect de l'invention est un aspirateur comportant au moins un suceur selon le premier aspect de l'invention. Advantageously, the longitudinal axis of the hatch is substantially perpendicular to the direction of movement of the nozzle. Advantageously, the vacuum nozzle comprises a removable motorized brush. This motorized brush can be removed by a user for maintenance purposes of brush change or even cleaning thereof. According to various embodiments, this brush may have different shapes and different means of rotation. Advantageously, the vacuum nozzle has wheels which define a ground clearance of the sole. In other words, the nozzle, and therefore the lower sole of the nozzle, is positioned at a predetermined height of the ground by the wheels. Casters are added under the nozzle at the sole. 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 : Other features and advantages of the present invention will appear 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:
- la figure 1 représente un suceur selon l'invention vu en perspective de dessus ; - Figure 1 shows a nozzle according to the invention seen in perspective from above;
- 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; - Figure 2 shows the nozzle of Figure 1 seen from below; FIG. 3 represents a view in perspective and from below of the suction nozzle;
- la figure 4 représente une vue de dessous en perspective et éclatée du suceur. 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 . - Figure 4 shows a bottom view in perspective and exploded of the nozzle. FIG. 1 represents a suction 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 smooth floor. At least two rollers 3 are also arranged under the sole 14. The nozzle 1 is in the general 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. 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. 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 . In a certain embodiment, there is disposed around the soleplate 14 a sealing lip or flap 4. This sealing flap 4 removes leaks between the smooth floor and the sole 14, and to have a good efficiency suction, the sealing strip 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 in This results in good suction of impurities from the ground because the air velocities in the channels 10 of the soleplate 14 are maximum, since all the air sucked there passes. The wheels 2 position in height the nozzle 1 relative to the ground. The sealing lip 4 shaves the ground, so as to eliminate air leakage between the ground and the sole 14, and openings 5 of the sealing strip 4 arranged directly in front of the channels 10 let the air through in these to entrain the impurities resting on the ground. FIG. 2 shows the soleplate 14 on which there are a plurality of suction channels open towards the ground and the suction channels converging from an outer edge of the soleplate 14 to a suction orifice 9 in aeraulic connection with a vacuum cleaner (not shown). Aeraulic connection means that the air flow that 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 connaître 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 nozzle 1 comprises a hatch 13 which is substantially in the same plane as the sole 14. This hatch 13 comprises the suction port 9 and suction channels 20 open to the ground . These suction channels 20 are arranged vis-à-vis the suction channels 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 a substantially similar profile. In the case shown in Figure 2, in addition to having their contiguous portions substantially similar, the channels 20 of the hatch 13 and the channels 10 of the sole 14 have substantially the same diameter over their entire length. This is to create a regular passage channel that allows the flow of air through not to experience a sudden change in flow. 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 diameter variation 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'accroché. Dans le cas présent, ce dispositif d'accroché 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 in FIG. 3, this flap 13 is removable and can be removed from the flange 14. This flap 13 is substantially rectangular and comprises a hooking device. In the present case, this hooking device consists of mechanical clips consisting on the one hand of pins 7 and on the other hand of grooves 6. Such a device allows a user to remove the hatch 13 without the aid of handling tools such as screwdrivers or Allen keys. Such a device therefore has the advantage of quickly removing the flap 13. To proceed, the user performs a simple mechanical pressure at the lugs 7 which has the effect of releasing them from the grooves 6 and maintaining the power remove the hatch 13. The reverse operation is also fast since it is sufficient for the user to slide the lugs 7 in the grooves 6 provided for this purpose and then apply a low pressure on the hatch 13 at these lugs 7 so that the hatch 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. 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'accroché. Ce dispositif d'accroché 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 1 1 . Ce système à baïonnette 1 1 permet de mettre en rotation la brosse 8 lorsque le système de mise en rotation de la brosse (non visible) est actif. When the user releases the hatch 13 of the nozzle 1, he can access a cavity 21 which is behind this hatch 13 and in the nozzle 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 runs from one end to the other of the hatch 13 and which extends in the direction of the length. 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 previously mentioned, the tip 30 of the triangular nozzle 1 is oriented in the direction of movement of the nozzle 1 when used in a normal mode of use. A brush 8 is visible in Figure 4 and in the context of the invention, the brush 8 is motorized and is removable. This brush is inserted into the cavity 21 and is held therein by a hooking device. This hanging 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, a groove 12 and on the other hand, and the other side of the brush, a bayonet system 1 1. This bayonet system 1 1 makes it possible to rotate the brush 8 when the system for rotating the brush (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 a flow of air which is sucked into 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 flow of air first passes through the channels 10 and then the channels 20 to arrive in the orifice 9 d suction. The addition of a hatch 13 protecting the brush 8 allows through the channels 20 of the hatch 13 to maintain a constant suction flow and not to reduce the quality suction.
On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation de l'invention décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
