Description

ASPIRATEUR ET SAC ETANCHE RECUPERATEUR DE DECHETS VACUUM CLEANER AND WATERPROOF WASTE BAG
La présente invention se rapporte au domaine des systèmes d'aspiration et plus particulièrement à des aspirateurs utilisés à des fins de nettoyage. La présente invention concerne plus particulièrement les aspirateurs destinés à aspirer des déchets de tout type et le cas échéant des déchets sous forme liquide.The present invention relates to the field of suction systems and more particularly to vacuum cleaners used for cleaning purposes. The present invention relates more particularly to vacuum cleaners intended to suck up waste of any type and, where appropriate, waste in liquid form.
La présente invention concerne également l'association d'un tel aspirateur avec un sac etanche récupérateur de déchets destiné à être logé dans ledit aspirateur.The present invention also relates to the association of such a vacuum cleaner with a waterproof waste recovery bag intended to be housed in said vacuum cleaner.
II est déjà connu d'utiliser des sacs jetables pour aspirateurs réalisés en matériau etanche. Le document GB-A-2 141 635 décrit un aspirateur du type cuve dans lequel on utilise un sac etanche positionné sur un support spécifique reposant sur ie fond de la cuve. La dépression réalisée dans l'aspirateur permet d'aspirer les déchets à l'intérieur dudit sac etanche et d'expulser de l'air filtré à l'aide d'une association d'un moteur, d'un ventilateur et d'un filtre. La structure de l'aspirateur est conçue de manière à ménager un espace libre autour du sac etanche disposé dans la cuve et de produire une circulation d'air autour de ce sac etanche. Cette circulation d'air à l'intérieur de la cuve permet d'équilibrer les pressions régnant à l'intérieur et à l'extérieur du sac etanche. De tels aspirateurs présentent un certain nombre d'inconvénients. En effet il est très difficile d'obtenir un équilibrage entre l'intérieur et l'extérieur du sac etanche. En outre l'utilisation d'un support spécifique nécessite d'une part des dimensions très précises dudit support et d'autre part augmente le nombre de pièces constitutives d'un tel appareillage. Par ailleurs, ii est évident qu'une fois l'opération de nettoyage terminée, l'utilisateur est confronté lors de l'ouverture de l'aspirateur au sac rempli de déchets, lesquels sont susceptibles de salir l'environnement nettoyé, en cas d'une manipulation aléatoire du sac. Le filtre utilisé dans ce système d'aspiration est également soumis à un colmatage important ou fréquent et nécessite donc un remplacement régulier. Il est également connu d'utiliser un moyen de filtration complémentaire associé à un sac etanche. Le document DE-G-90 17 798.3 décrit un aspirateur du type cuve dans lequel est utilisé un réservoir à poussière interchangeable constitué d'un sac à poussière etanche et d'une partie filtrante maintenus ensemble par une partie porteuse annulaire, laquelle est prévue pour s'appuyer sur un rebord annulaire ménagé dans la cuve de l'appareil. L'appareil comporte également une prise de pression entre la cuve, à l'extérieur du sac etanche, et le conduit d'aspiration de l'appareil, établissant ainsi une dépression plus forte à l'extérieur du sac etanche qu'à l'intérieur de celui-ci, l'air devant dans ce cas traverser successivement le moyen de filtration complémentaire et le filtre moteur. Dans ce type de réalisation la présence d'un moyen de filtration complémentaire solidaire du sac à poussière évite que l'utilisateur ait à manipuler un sac à poussière plein dont le contenu soit à l'air libre. Cependant de tels aspirateurs présentent l'inconvénient d'une installation peu aisée du sac à poussière dans la cuve de l'appareil. En effet, il est préférable de déployer les parois du sac nouvellement introduit dans la cuve de l'appareil afin de faciliter l'action de la dépression relative régnant à l'extérieur du sac et d'éviter que lesdites parois ne viennent obturer le moyen de filtration complémentaire.It is already known to use disposable bags for vacuum cleaners made of waterproof material. Document GB-A-2 141 635 describes a tank type vacuum cleaner in which a waterproof bag is used positioned on a specific support resting on the bottom of the tank. The vacuum produced in the vacuum cleaner makes it possible to aspirate the waste inside said waterproof bag and to expel filtered air using a combination of a motor, a fan and a filtered. The structure of the vacuum cleaner is designed so as to provide a free space around the waterproof bag placed in the tank and to produce an air circulation around this waterproof bag. This circulation of air inside the tank makes it possible to balance the pressures prevailing inside and outside the waterproof bag. Such vacuum cleaners have a number of drawbacks. Indeed it is very difficult to obtain a balance between the inside and the outside of the waterproof bag. In addition, the use of a specific support requires on the one hand very precise dimensions of said support and on the other hand increases the number of component parts of such an apparatus. Furthermore, it is obvious that once the cleaning operation has been completed, the user is confronted when opening the vacuum cleaner with the bag filled with waste, which is likely to dirty the cleaned environment, in the event of '' random manipulation of the bag. The filter used in this suction system is also subject to significant or frequent clogging and therefore requires regular replacement. It is also known to use an additional filtration means associated with a waterproof bag. Document DE-G-90 17 798.3 describes a vacuum cleaner of the tank type in which an interchangeable dust tank is used consisting of a sealed dust bag and a filtering part held together by an annular carrying part, which is provided for lean on an annular rim made in the tank of the appliance. The device also includes a pressure tap between the tank, outside the waterproof bag, and the suction pipe of the device, thus establishing a stronger vacuum outside the waterproof bag than inside thereof, the air in this case must pass successively through the additional filtration means and the engine filter. In this type of embodiment, the presence of an additional filtration means integral with the dust bag prevents the user from having to handle a full dust bag, the contents of which are in the open air. However, such vacuum cleaners have the drawback of an awkward installation of the dust bag in the tank of the appliance. In fact, it is preferable to deploy the walls of the bag newly introduced into the tank of the apparatus in order to facilitate the action of the relative depression prevailing outside the bag and to prevent said walls from closing off the means. additional filtration.

L'objet de la présente invention consiste également à réaliser des sacs étanches dont la mise en place dans l'aspirateur est simplifiée et dont l'utilisation procure à l'utilisateur plus de propreté et un colmatage moins fréquent du filtre associé au système d'aspiration.

The objects assigned to the present invention are achieved by means of a vacuum cleaner comprising a suction system, a compartment placed above a tank intended to contain an impermeable waste recovery bag, a pipe opening into the impermeable bag. so as to circulate the flow of air sucked through the pipe, in an internal volume of the waterproof bag and in the suction system provided with a filter for expelling filtered air, a pressure tap communicating with the tank, a complementary filtration means associated with the waterproof bag covering at least partially the internal volume of said waterproof bag, allowing on the one hand to create a pressure drop in the air flow sucked in and on the other hand to thus generate in the tank outside the waterproof bag a vacuum greater than that prevailing inside said waterproof bag, characterized in that the waterproof bag is designed to be placed in the tank independently e additional filtration means.

L'aspirateur représenté par exemple à la figure 1 est constitué d'une cuve 3 disposée en dessous d'un compartiment 1 contenant un système d'aspiration 2.The vacuum cleaner represented for example in FIG. 1 consists of a tank 3 arranged below a compartment 1 containing a suction system 2.
La cuve 3 est destinée à recevoir un sac etanche 20 récupérateur de déchets. Un tuyau 4 débouche dans le sac etanche 20 de manière à faire circuler un flux d'air aspiré 12 à travers le tuyau 4, dans un volume interne 21 du sac etanche 20 et à travers le système d'aspiration 2. Ce dernier est composé d'un moteur électrique 2c associé à une turbine 2b générant une dépression à l'intérieur de l'aspirateur. Un filtre 2a pour expulser de l'air filtré est également prévu dans le système d'aspiration 2.The tank 3 is intended to receive a waterproof bag 20 for collecting waste. A pipe 4 opens into the waterproof bag 20 so as to circulate a flow of aspirated air 12 through the pipe 4, into an internal volume 21 of the waterproof bag 20 and through the suction system 2. The latter is composed an electric motor 2c associated with a turbine 2b generating a vacuum inside the vacuum cleaner. A filter 2a for expelling filtered air is also provided in the suction system 2.
La figure 2 schématise de façon simplifiée les circulations des différents flux d'air. Ainsi un flux d'air aspiré 12 traverse le tuyau 4 pour pénétrer dans l'aspirateur et, est expulsé de ce dernier par l'intermédiaire de la turbine 2b sous forme de flux d'air filtré 13. Un flux d'air de refroidissement 10, 11 est également utilisé pour refroidir le moteur 2c lors de son fonctionnement. Il est évident que l'extrémité du tuyau 4 située hors de l'aspirateur se termine par un tuyau du type flexible et par un dispositif de nettoyage du type suceur ou brosse ou par d'autres moyens de nettoyage connus.Figure 2 schematically shows the circulation of the different air flows in a simplified manner. Thus a flow of aspirated air 12 crosses the pipe 4 to enter the vacuum cleaner and is expelled from the latter by means of the turbine 2b in the form of a filtered air flow 13. A flow of cooling air 10, 11 is also used to cool the engine 2c during its operation. It is It is obvious that the end of the pipe 4 situated outside the vacuum cleaner ends in a hose of the flexible type and in a cleaning device of the nozzle or brush type or by other known cleaning means.
L'aspirateur conforme à l'invention comprend également des moyens permettant de réaliser une dépression autour du sac etanche 20 et ceci à l'intérieur de la cuve 3. De tels moyens sont indispensables pour obtenir le gonflage du sac etanche 20, lorsqu'il est disposé à l'intérieur de la cuve et lorsque l'aspirateur est mis en fonctionnement. Le sac etanche 20 est ainsi associé à un moyen de filtration 25 complémentaire recouvrant au moins partiellement le volume interne 21 dudit sac etanche 20 et permettant de créer une perte de charge dans le flux d'air aspiré 12.The vacuum cleaner according to the invention also comprises means making it possible to produce a vacuum around the waterproof bag 20 and this inside the tank 3. Such means are essential for obtaining the inflation of the waterproof bag 20, when is placed inside the tank and when the vacuum cleaner is started. The waterproof bag 20 is thus associated with a complementary filtration means 25 covering at least partially the internal volume 21 of said waterproof bag 20 and making it possible to create a pressure drop in the flow of aspirated air 12.
Le moyen de filtration 25 complémentaire permet également de transmettre dans la cuve 3 à l'extérieur du sac etanche 20 une dépression supérieure à celle régnant à l'intérieur dudit sac etanche 20. L'aspirateur conforme à l'invention comprend donc sur le chemin du flux d'air aspiré 12, respectivement le tuyau 4, le volume interne 21 du sac etanche 20, le moyen de filtration 25 complémentaire et le filtre 2a associé au système d'aspiration 2.The complementary filtration means 25 also makes it possible to transmit into the tank 3 outside the waterproof bag 20 a vacuum greater than that prevailing inside said waterproof bag 20. The vacuum cleaner according to the invention therefore comprises on the way of the suction air flow 12, respectively the pipe 4, the internal volume 21 of the waterproof bag 20, the additional filtration means 25 and the filter 2a associated with the suction system 2.
Avantageusement le moyen permettant de réaliser une dépression dans la cuve 3 et autour du sac d'étanche 20 est une prise de pression 5 communiquant d'une part avec la cuve 3 et d'autre part avec un espace 6 s'étendant au moins partiellement entre le filtre 2a et le moyen de filtration complémentaire 25. L'espace 6 s'étend de préférence au voisinage de l'interface entre le compartiment 1 et la cuve 3. Dans l'exemple de réalisation de l'aspirateur conforme à l'invention représenté aux figures 1 et 2, cet espace 6 s'étend principalement au-dessus et en regard du moyen de filtration 25 complémentaire, lequel réalise ainsi une séparation, bien évidemment perméable au flux d'air aspiré 12, entre le volume interne 21 et le système d'aspiration 2. La prise de pression 5 est par exemple réalisée avec une ou plusieurs portions de conduites débouchant sur le espace 6 ainsi que sur un volume libre 3a s'étendant autour du sac etanche 20. Le montage ou l'assemblage du compartiment 1 sur la cuve 3 est effectué de manière connue avec des moyens de fixation connus afin d'obtenir une étanchéité parfaite et par conséquent un cloisonnement du volume libre 3a. Une telle conception permet d'éviter une prise d'air aléatoire ou accidentelle non compensée par la prise de pression 5. Un tel fonctionnement accidentel aurait pour conséquence d'aspirer le sac etanche 20 vers le moyen de filtration 25 complémentaire et d'obstruer le chemin du flux d'air aspiré 12. Le moyen de filtration complémentaire 25 permet donc conformément à l'invention d'obtenir un différentiel de pression entre le volume interne 21 et le espace 6. Lors du fonctionnement de l'aspirateur, une dépression plus importante que celle régnant dans le volume interne 21 , est ainsi obtenue dans le espace 6 et par conséquent dans le volume libre 3a. Un différentiel de pression de l'ordre de quelques millibars et de préférence de 10 millibars en amont et aval du moyen de filtration 25 complémentaire permet ainsi d'obtenir un gonflage et/ou un dépliage du sac etanche 20.Advantageously, the means making it possible to produce a vacuum in the tank 3 and around the waterproof bag 20 is a pressure tap 5 communicating on the one hand with the tank 3 and on the other hand with a space 6 extending at least partially. between the filter 2a and the complementary filtration means 25. The space 6 preferably extends in the vicinity of the interface between the compartment 1 and the tank 3. In the embodiment of the vacuum cleaner according to invention shown in Figures 1 and 2, this space 6 extends mainly above and opposite the complementary filtration means 25, which thus achieves a separation, obviously permeable to the flow of aspirated air 12, between the internal volume 21 and the suction system 2. The pressure tap 5 is, for example, produced with one or more portions of pipes leading to the space 6 as well as to a free volume 3a extending around the waterproof bag 20. The assembly or assembly of the compartment 1 on the tank 3 is carried out in a known manner with known fixing means in order to obtain a perfect seal and therefore a partitioning of the free volume 3a. Such a design makes it possible to avoid a random or accidental air intake not compensated by the pressure intake 5. Such accidental operation would have the consequence of sucking the waterproof bag 20 towards the complementary filtration means 25 and of obstructing the path of the aspirated air flow 12. The complementary filtration means 25 therefore makes it possible, in accordance with the invention, to obtain a pressure differential between the internal volume 21 and the space 6. During the operation of the vacuum cleaner, a more important than that prevailing in the internal volume 21, is thus obtained in the space 6 and consequently in the free volume 3a. A pressure differential of the order of a few millibars and preferably 10 millibars upstream and downstream of the complementary filtration means 25 thus makes it possible to obtain inflation and / or unfolding of the waterproof bag 20.
L'aspirateur conforme à l'invention est, selon un exemple de réalisation, constitué du compartiment 1 , du moyen de filtration 25 complémentaire, du sac etanche 20 et de la cuve 3 réalisant ainsi un ensemble de pièces facilement démontables les unes par rapport aux autres. Le compartiment 1 est de préférence monté de façon amovible et etanche sur la cuve 3. Le moyen de filtration 25 complémentaire est avantageusement réalisé avec un ou des matériau(x) rigide(s), perméable(s) au flux d'air aspiré 12 et présentant une ouverture 26, laquelle est traversée par une extrémité 4a du tuyau 4 lorsque ledit moyen de filtration 25 complémentaire est mis en place dans l'aspirateur. Les matériaux constitutifs du moyen de filtration 25 complémentaire sont par exemple du papier ou des feuilles cartonnées ou tout autre matériau de synthèse présentant des propriétés de filtration adaptées d'une part à la qualité de la filtration désirée avec ce moyen de filtration complémentaire et d'autre part au différentiel de pression souhaité en amont et en aval du moyen de filtration 25 complémentaire. L'ouverture 26 est avantageusement pourvue de languettes élastiques obturant cette même ouverture 26 lorsque l'extrémité 4a est dégagée du moyen de filtration 25.The vacuum cleaner according to the invention is, according to an exemplary embodiment, consisting of compartment 1, of the additional filtration means 25, of the waterproof bag 20 and of the tank 3 thus producing a set of parts that can be easily dismantled relative to the other. The compartment 1 is preferably removably and tightly mounted on the tank 3. The complementary filtration means 25 is advantageously made with one or more rigid material (s), permeable (s) to the flow of aspirated air 12 and having an opening 26, which is traversed by one end 4a of the pipe 4 when said additional filtration means 25 is put in place in the vacuum cleaner. The constituent materials of the complementary filtration means 25 are for example paper or cardboard sheets or any other synthetic material having filtration properties adapted on the one hand to the quality of filtration desired with this complementary filtration means and on the other hand to the desired pressure differential upstream and downstream of the additional filtration means. The opening 26 is advantageously provided with elastic tongues closing this same opening 26 when the end 4a is released from the filtration means 25.
La cuve 3 présente avantageusement dans sa partie supérieure un bord périphérique 3b s'étendant par exemple selon un plan horizontal vers l'intérieur de ladite cuve 3, de manière à réaliser un support pour ie compartiment 1 , lorsque ce dernier est assemblé avec la cuve 3. Ainsi selon une association conforme à la présente invention, le sac etanche 20 présente par exemple une configuration similaire à un sac poubelle, avec de préférence des dimensions adaptées à la taille de l'aspirateur. Une fois disposé dans la cuve 3, le sac etanche 20 repose avec son extrémité supérieure 22 sur le bord périphérique 3b. Il en est de même pour le moyen de filtration 25 complémentaire. Ce dernier, tout en réalisant un média filtrant, peut aussi être pourvu d'une portion repliable sur l'ouverture 26.The tank 3 advantageously has in its upper part a peripheral edge 3b extending for example along a horizontal plane towards the inside of said tank 3, so as to produce a support for the compartment 1, when the latter is assembled with the tank 3. Thus according to an association according to the present invention, the waterproof bag 20 has for example a configuration similar to a garbage bag, preferably with dimensions adapted to the size of the vacuum cleaner. Once placed in the tank 3, the waterproof bag 20 rests with its upper end 22 on the peripheral edge 3b. It is the same for the complementary filtration means. The latter, while providing a filter medium, can also be provided with a foldable portion on the opening 26.
La prise de pression 5 telle que représentée à la figure 1 est avantageusement solidaire du compartiment 1 ou bien réalise une partie intégrante de ce dernier. Le bord périphérique 3b est également pourvu d'un orifice 3c lequel est traversé par une portion de la prise de pression 5 lorsque le compartiment 1 est mis en place sur la cuve 3. Il est évident que la prise de pression 5 est réalisée de façon à faire saillie hors d'une zone d'appui 1a que présente le compartiment 1 pour venir en appui ou reposer sur le bord périphérique 3b. La prise de pression 5 permet alors de percer l'extrémité supérieure 22 du sac etanche 20. Le passage de la prise de pression 5 dans l'orifice 3c peut se faire à l'aide de moyens connus en combinaison avec un joint d'étanchéité par exemple. L'extrémité 4a du tuyau 4 présente également des dimensions adaptées à son passage dans l'ouverture 26. Selon une variante de réalisation de l'aspirateur conforme à l'invention une ou plusieurs prises de pression 5 sont réalisées directement sur le bord périphérique 3b tel que cela est représenté par exemple sur la figure 2. Il appartient ainsi à l'utilisateur qui met en place le sac etanche 20 dans la cuve 3, de positionner correctement et/ou de percer l'extrémité supérieure 22 du sac et éventuellement le moyen de filtration 25 complémentaire, de façon à permettre à la prise de pression 5 de remplir la fonction qui lui est assignée. Dans ce cas, la périphérie du moyen de filtration 25 complémentaire s'étend de préférence au dessus du bord périphérique 3b, et se trouve comprimée entre ledit bord périphérique 3b et la zone d'appui du compartiment 1.The pressure tap 5 as shown in FIG. 1 is advantageously secured to compartment 1 or else makes an integral part of the latter. The peripheral edge 3b is also provided with an orifice 3c which is crossed by a portion of the pressure tap 5 when the compartment 1 is put in place on the tank 3. It is obvious that the pressure tap 5 is made so to protrude out of a support zone 1a presented by the compartment 1 in order to come to bear or rest on the peripheral edge 3b. The pressure tap 5 then makes it possible to pierce the upper end 22 of the waterproof bag 20. The passage of the pressure tap 5 in the orifice 3c can be done using known means in combination with a seal. for example. The end 4a of the pipe 4 also has dimensions adapted to its passage through the opening 26. According to an alternative embodiment of the vacuum cleaner according to the invention one or more pressure taps 5 are produced directly on the peripheral edge 3b as shown for example in FIG. 2. It is thus up to the user who sets up the waterproof bag 20 in the tank 3, to correctly position and / or pierce the upper end 22 of the bag and possibly the additional filtration means 25, so as to allow the pressure tap 5 to fulfill the function assigned to it. In this case, the periphery of the complementary filtration means 25 preferably extends above the peripheral edge 3b, and is compressed between said peripheral edge 3b and the support zone of the compartment 1.
De préférence le moyen de filtration 25 complémentaire est constitué d'au moins deux couches 30, 31 de matériau de synthèse fibreux non tissé, tel que montré à la figure 3. La couche 30 traversée par le flux d'air aspiré 12 avant la couche 31 est plus épaisse que ladite couche 31 traversée ensuite. L'épaisseur de la couche 30 permet d'obtenir une filtration en volume qui a pour but de retarder le colmatage de la couche 31 par des particules de petite taille. La couche 31 fait fonction de filtration de poussière. Elle empêche les particules fines de traverser le moyen de filtration 25 complémentaire. Le moyen de filtration 25 complémentaire est préférentiellement composé de matériaux hydrophobes qui ne retiennent pas l'eau, voire même qui la repoussent, dans le cas où l'appareil est utilisé avec des déchets liquides ou humides. La couche 30 peut par exemple être constituée d'un matériau en fibres polyester, et la couche 31 , d'un matériau en microfibres de polypropylène, l'un ou l'autre de ces matériaux pouvant être chargés électriquement.Preferably the complementary filtration means 25 consists of at least two layers 30, 31 of nonwoven fibrous synthetic material, as shown in FIG. 3. The layer 30 traversed by the flow of aspirated air 12 before the layer 31 is thicker than said layer 31 then passed through. The thickness of the layer 30 makes it possible to obtain a volume filtration which has the aim of delaying the clogging of the layer 31 by small particles. Layer 31 acts as a dust filtration. It prevents fine particles from passing through the complementary filtration means. The complementary filtration means 25 is preferably composed of hydrophobic materials which do not retain water, or even repel it, in the case where the apparatus is used with liquid or wet waste. The layer 30 may for example be made of a polyester fiber material, and the layer 31, of a polypropylene microfiber material, either of these materials being capable of being electrically charged.
De préférence, le moyen de filtration 25 présente une portion adhesive 25a pour réaliser l'assemblage ou la liaison avec la partie du sac etanche 20 recouvrant l'anneau périphérique 3c. A titre de variante, la portion adhesive 25a peut être prévue sur le sac etanche 20. La figure 3 montre également la prise de pression 5 ménagée dans le bord périphérique 3b, à l'extérieur de l'anneau périphérique 3c, mettant ainsi en communication, l'espace 6 et le volume libre 3a. Le compartiment 1 est avantageusement rapporté sur la cuve 3 de façon etanche, par exemple au moyen d'un joint annulaire 34, tel que représenté à la figure 3.Preferably, the filtration means 25 has an adhesive portion 25a for making the assembly or the connection with the part of the waterproof bag 20 covering the peripheral ring 3c. Alternatively, the adhesive portion 25a can be provided on the waterproof bag 20. FIG. 3 also shows the pressure tap 5 formed in the peripheral edge 3b, outside the peripheral ring 3c, thus putting in communication , space 6 and free volume 3a. The compartment 1 is advantageously attached to the tank 3 in a sealed manner, for example by means of an annular seal 34, as shown in FIG. 3.
Selon une variante de réalisation de l'invention représentée à la figure 4, le sac etanche 20 est pourvu autour de son extrémité 22, d'une bande rigide 22a, par exemple inextensible et/ou adhesive, prévue à des fins de mise en place autour du rebord de la cuve. Le sac etanche 20 est donc glissé sur un support du type anneau périphérique 3c solidaire du bord périphérique 3b. Le sac etanche 20 est monté tel un chapeau ou enfilé sur la cuve 3, à l'aide de cette bande rigide 22a, avant d'être retourné pour lui permettre de se loger à l'intérieur de la cuve 3, avec la bande rigide 22a restant fixée sur l'anneau périphérique 3c. Une telle mise en place est effectuée de manière extrêmement simple, comme le montre la figure 4 notamment. Le moyen de filtration 25 est ensuite rapporté sur la cuve 3 et plus précisément sur l'anneau périphérique 3c. A titre de variante, une portion adhesive peut être prévue sur la bande rigide 22a.According to an alternative embodiment of the invention shown in FIG. 4, the waterproof bag 20 is provided around its end 22 with a rigid band 22a, by inextensible and / or adhesive example, provided for placement purposes around the rim of the tank. The waterproof bag 20 is therefore slid onto a support of the peripheral ring type 3c secured to the peripheral edge 3b. The waterproof bag 20 is mounted like a hat or threaded onto the tank 3, using this rigid strip 22a, before being turned over to allow it to be housed inside the tank 3, with the rigid strip 22a remaining fixed on the peripheral ring 3c. Such an installation is carried out in an extremely simple manner, as shown in FIG. 4 in particular. The filtration means 25 is then attached to the tank 3 and more specifically to the peripheral ring 3c. Alternatively, an adhesive portion may be provided on the rigid strip 22a.
Dans une autre variante, non représentée aux figures, le sac etanche 20 comporte des liens de fermeture disposés au niveau de son extrémité 22. Ces liens permettent de maintenir l'extrémité 22 du sac 20 autour de l'anneau périphérique 3c de la cuve 3, avant la mise en place du moyen de filtration 25 complémentaire. Ces liens permettent aussi de refermer aisément le sac 20 après utilisation en enfermant le moyen de filtration 25 complémentaire à l'intérieur dudit sac. L'utilisateur peut ainsi extraire de son aspirateur un sac fermé de manière complètement etanche.In another variant, not shown in the figures, the waterproof bag 20 comprises closure links arranged at its end 22. These links make it possible to maintain the end 22 of the bag 20 around the peripheral ring 3c of the tank 3 , before the installation of the additional filtration means 25. These links also make it possible to easily close the bag 20 after use by enclosing the complementary filtration means 25 inside said bag. The user can thus extract a completely sealed bag from his vacuum cleaner.
Selon une autre variante de réalisation de l'aspirateur conforme à l'invention le moyen de filtration 25 complémentaire est fixé au sac etanche 20, ce dernier étant destiné à être utilisé dans un aspirateur et associé au moyen de filtration 25 complémentaire recouvrant l'accès au volume interne 21 dudit sac etanche 20 d'une part et présentant une ouverture 26 susceptible d'être traversée par l'extrémité 4a du tuyau 4 lorsque le moyen de filtration 25 complémentaire est monté dans l'aspirateur. Le sac etanche 20 est de préférence fixé de manière indissociable au moyen de filtration 25. Une exemple de réalisation du sac etanche 20 conforme à l'invention est ainsi représenté à la figure 7. La configuration générale du sac s'étendant à l'intérieur de la cuve 3 est quelconque et s'adapte de préférence à la configuration générale de la cuve 3 de façon à fournir à l'utilisateur un moyen récupérateur de déchets de contenance maximale.According to another alternative embodiment of the vacuum cleaner according to the invention, the additional filtration means 25 is fixed to the waterproof bag 20, the latter being intended for use in a vacuum cleaner and associated with the additional filtration means 25 covering the access to the internal volume 21 of said waterproof bag 20 on the one hand and having an opening 26 capable of being traversed by the end 4a of the pipe 4 when the additional filtration means 25 is mounted in the vacuum cleaner. The waterproof bag 20 is preferably fixed inseparably to the filtration means 25. An embodiment of the waterproof bag 20 according to the invention is thus shown in Figure 7. The general configuration of the bag extending inside of the tank 3 is arbitrary and preferably adapts to the general configuration of the tank 3 so as to provide the user with a means for recovering waste from maximum capacity.
Le sac etanche 20 représenté à la figure 7 épouse une forme générale cylindrique lorsqu'il est déplié et présente dans sa partie supérieure le moyen de filtration 25 complémentaire. Ce dernier est soudé, collé ou fixé par tout moyen connu sur le sac etanche 20.The waterproof bag 20 shown in FIG. 7 takes on a generally cylindrical shape when it is unfolded and has in its upper part the complementary filtration means 25. The latter is welded, glued or fixed by any known means to the waterproof bag 20.
Le sac etanche 20 présente de préférence un anneau rigide 27 assurant une cohésion mécanique avec le moyen de filtration 25 complémentaire d'une part et facilitant la mise en place du sac dans l'aspirateur d'autre part. L'anneau rigide 27 est par exemple utilisé comme interface entre l'extrémité supérieure 22 du sac etanche 20 et le moyen de filtration complémentaire 25. Une telle conception permet de faciliter le procédé d'assemblage du sac etanche 20, sachant que le matériau constitutif dudit sac etanche 20 est un film plastique mince et souple. L'anneau rigide 27 peut également présenter un ou plusieurs trous de dimensions adaptés au passage de la prise de pression 5 et/ou au positionnement du sac etanche 20 dans la cuve 3 de l'aspirateur en coopérant avec des plots de positionnement, non représentés aux figures, répartis sur le bord périphérique 3b. L'anneau rigide 27 peut également être constitué d'un matériau compressible lui conférant ainsi un rôle d'étanchéité lorsque le compartiment 1 est mis en place, ou fixé sur la cuve 3. Tout matériau du type carton ou caoutchouc ou plastique ou une combinaison desdits matériaux est envisageable pour réaliser un tel anneau rigide 27. Ce dernier présente tout de même une souplesse suffisante pour ne pas entraver l'étanchéite obtenue entre le compartiment 1 et la cuve 3.The waterproof bag 20 preferably has a rigid ring 27 ensuring mechanical cohesion with the filtration means 25 complementary on the one hand and facilitating the positioning of the bag in the vacuum cleaner on the other hand. The rigid ring 27 is for example used as an interface between the upper end 22 of the waterproof bag 20 and the complementary filtration means 25. Such a design makes it possible to facilitate the process of assembling the waterproof bag 20, knowing that the constituent material said waterproof bag 20 is a thin and flexible plastic film. The rigid ring 27 may also have one or more holes of dimensions adapted to the passage of the pressure tap 5 and / or to the positioning of the waterproof bag 20 in the tank 3 of the vacuum cleaner by cooperating with positioning pads, not shown. in the figures, distributed over the peripheral edge 3b. The rigid ring 27 can also be made of a compressible material thus giving it a sealing role when the compartment 1 is put in place, or fixed on the tank 3. Any material of the cardboard or rubber or plastic type or a combination said materials can be envisaged to produce such a rigid ring 27. The latter nevertheless has sufficient flexibility so as not to hinder the sealing obtained between compartment 1 and tank 3.
Un tel assemblage peut également être obtenu, selon une autre variante de réalisation de l'aspirateur conforme à l'invention, avec un scellage etanche sur toute une périphérie externe 28 de l'anneau rigide 27, par conséquent sur le bord périphérique 3b. Des trous 29 répartis sur le même anneau rigide 27 mais à l'intérieur de cette périphérie externe 28 sont alors utilisés pour communiquer avec la prise de pression 5 ou pour être traversés par ladite prise de pression 5. Cette dernière sera avantageusement réalisée avec une rainure périphérique ménagée dans la portion de la zone d'appui 1a du compartiment 1 qui vient en appui sur le bord périphérique 3b de façon à recouvrir au moins l'un des trous 29. Il est évident qu'une telle rainure périphérique non représentée aux figures devra communiquer librement avec l'espace 6 ou règne une dépression que l'on veut transmettre autour du sac etanche 20.Such an assembly can also be obtained, according to another alternative embodiment of the vacuum cleaner according to the invention, with a tight seal over an entire outer periphery 28 of the rigid ring 27, therefore on the peripheral edge 3b. Holes 29 distributed on the same rigid ring 27 but inside this external periphery 28 are then used to communicate with the pressure tap 5 or to be crossed by said pressure tap 5. The latter will advantageously be made with a peripheral groove formed in the portion of the support zone 1a of the compartment 1 which comes to bear on the peripheral edge 3b so as to cover at least one of the holes 29. It is obvious that such a peripheral groove not shown in the figures will have to communicate freely with the space 6 or there will be a depression which one wishes to transmit around the waterproof bag 20.
Selon une autre variante de réalisation de l'invention, représentée à la figure 5, l'aspirateur comporte un déflecteur 32 disposé sur le chemin naturel du flux d'air aspiré 12 entre le moyen de filtration 25 complémentaire et le filtre 2a. Le déflecteur 32 est de préférence muni de plots 32a, lesquels viennent appuyer sur le moyen de filtration 25 complémentaire, ménageant ainsi un espace entre la paroi du déflecteur 32 en regard avec le moyen de filtration 25 et ledit moyen de filtration 25. Ce déflecteur permet de répartir de façon plus homogène le flux d'air 12 sur toute la surface du moyen de filtration 25 complémentaire. Le déflecteur 32 est avantageusement fixé au compartiment 1 , par exemple au niveau du filtre 2a.According to another alternative embodiment of the invention, represented in FIG. 5, the vacuum cleaner comprises a deflector 32 arranged on the natural path of the flow of aspirated air 12 between the complementary filtration means 25 and the filter 2a. The deflector 32 is preferably provided with studs 32a, which press on the complementary filtration means 25, thus leaving a space between the wall of the deflector 32 facing the filtration means 25 and said filtration means 25. This deflector allows to distribute the air flow 12 more evenly over the entire surface of the complementary filtration means 25. The deflector 32 is advantageously fixed to the compartment 1, for example at the level of the filter 2a.
Selon une autre variante de réalisation de l'invention, représentée notamment à la figure 6, l'aspirateur comporte une platine 33 dans laquelle est inséré le moyen de filtration 25 complémentaire. La platine 33 est avantageusement munie d'un rebord annulaire 35 et d'ergots 36 disposés sur la paroi interne du montant 37, prévus pour retenir le moyen de filtration 25 complémentaire, ainsi que d'une portion de tube 34 destinée à prolonger l'extrémité 4b du tuyau 4 prévue pour s'insérer dans l'ouverture 26 du moyen de filtration 25. De manière avantageuse, la platine 33 est munie de moyens de centrage 38 afin d'assurer un positionnement correct sur la cuve 3. La figure 6 montre les moyens de centrage 38 prévus pour s'insérer dans les orifices ménagés dans la paroi de la cuve 3 pour réaliser une prise de pression 5, lesdits moyens de centrage 38 étant eux même traversés par un orifice 38a.According to another alternative embodiment of the invention, shown in particular in Figure 6, the vacuum cleaner comprises a plate 33 in which is inserted the complementary filtration means 25. The plate 33 is advantageously provided with an annular rim 35 and lugs 36 arranged on the internal wall of the upright 37, designed to retain the additional filtration means 25, as well as with a portion of tube 34 intended to extend the end 4b of the pipe 4 provided for insertion into the opening 26 of the filtration means 25. Advantageously, the plate 33 is provided with centering means 38 in order to ensure correct positioning on the tank 3. FIG. 6 shows the centering means 38 provided for insertion into the orifices provided in the wall of the tank 3 to produce a pressure tap 5, said centering means 38 being themselves traversed by an orifice 38a.
L'utilisateur bénéficie ainsi d'un positionnement plus aisé du moyen de filtration 25 complémentaire grâce notamment à la rigidité apportée par la platine 33. La platine 33 permet également à l'utilisateur d'extraire avec plus de facilité le sac etanche 20 rempli.The user thus benefits from easier positioning of the filtration means 25 complementary thanks in particular to the rigidity provided by the plate 33. The plate 33 also allows the user to more easily extract the sealed bag 20 filled.
A titre de variante, le déflecteur 32 peut être fixé à la platine 33.As a variant, the deflector 32 can be fixed to the plate 33.
A titre de variantes complémentaires, il est prévu que le moyen de filtration 25 complémentaire soit lavable et réutilisable. Ce moyen peut alors être constitué par exemple d'une ou plusieurs couches de matériau de synthèse, ou d'une toile tendue sur la platine 33. On peut ainsi disposer de moyens de filtration adaptés aux travaux à effectuer.As additional variants, provision is made for the additional filtration means 25 to be washable and reusable. This means can then consist for example of one or more layers of synthetic material, or a fabric stretched over the plate 33. It is thus possible to have filtration means suitable for the work to be carried out.
On peut aussi envisager d'utiliser l'aspirateur conforme à l'invention avec le moyen de filtration 25 complémentaire rapporté sur la cuve 3, sans le sac etanche 20, ledit moyen de filtration 25 étant éventuellement inséré dans la platine 33. On peut également envisager que le moyen de filtration 25 complémentaire soit constitué de plus de deux couches 30, 31 , par exemple que le moyen de filtration 25 complémentaire soit constitué d'une première couche très grossière arrêtant les particules de taille importante mais légères telles que cheveux, poils, etc. une deuxième couche assurant une filtration en épaisseur des particules fines et une troisième couche assurant l'arrêt de ces particules.One can also consider using the vacuum cleaner according to the invention with the additional filtration means 25 attached to the tank 3, without the waterproof bag 20, said filtration means 25 being possibly inserted in the plate 33. It is also possible consider that the additional filtration means 25 consist of more than two layers 30, 31, for example that the additional filtration means 25 consist of a very coarse first layer stopping large but light particles such as hair, hair , etc. a second layer ensuring a filtration in thickness of the fine particles and a third layer ensuring the stopping of these particles.
La présente invention est donc mise en oeuvre à l'aide du moyen de filtration 25 complémentaire dans un aspirateur déjà pourvu d'un filtre 2a associé au système d'aspiration 2 pour assainir le flux d'air aspiré 12. Une telle utilisation du moyen de filtration 25 complémentaire permet d'améliorer la filtration du flux d'air aspiré 12 et de créer une dépression autour du sac etanche 20, récupérateur de déchets, disposé dans l'aspirateur. Lorsqu'une personne veut utiliser un aspirateur conforme à l'invention, il lui suffit de disposer un sac etanche 20 dans la cuve 3, de rapporter sur l'ensemble ainsi constitué le moyen de filtration 25 complémentaire éventuellement inséré dans la platine 33, et de refermer ensuite le compartiment 1 sur la cuve 3. L'aspirateur est alors prêt pour une utilisation.The present invention is therefore implemented using the complementary filtration means 25 in a vacuum cleaner already provided with a filter 2a associated with the suction system 2 to sanitize the flow of aspirated air 12. Such use of the means 25 additional filtration improves the filtration of the air flow sucked 12 and create a vacuum around the waterproof bag 20, waste collector, disposed in the vacuum cleaner. When a person wants to use a vacuum cleaner in accordance with the invention, it suffices for him to have a waterproof bag 20 in the tank 3, to add to the assembly thus formed the additional filtration means 25 possibly inserted in the plate 33, and then close compartment 1 on tank 3. The vacuum cleaner is then ready for use.
Un avantage d'un aspirateur conforme à la présente invention réside dans la simplicité d'utilisation d'un tel aspirateur. En effet il suffit de désolidariser le compartiment 1 de la cuve 3, de mettre en place le sac etanche 20 à l'intérieur de la cuve 3, de mettre en place le moyen de filtration 25 complémentaire, lequel peut être éventuellement inséré dans la platine 33, et de refermer ensuite le compartiment 1 sur la cuve 3. L'aspirateur est ainsi prêt pour une utilisation.An advantage of a vacuum cleaner according to the present invention lies in the simplicity of use of such a vacuum cleaner. In fact, it suffices to separate the compartment 1 from the tank 3, to put in place the waterproof bag 20 inside the tank 3, to put in place the complementary filtration means 25, which can optionally be inserted in the plate 33, and then close compartment 1 on the tank 3. The vacuum cleaner is thus ready for use.
Un avantage complémentaire d'un aspirateur conforme à la présente invention réside dans l'installation du sac etanche 20 dans la cuve 3. L'utilisateur dispose le sac 20 dans la cuve 3 et commence à le déployer contre les parois. Ainsi l'inconvénient majeur de voir le sac 20 entraîné contre le moyen de filtration 25 complémentaire par le flux d'air 12 avant qu'il ne soit déployé sous l'effet de la dépression créée par le flux d'air 12 passant à travers le moyen de filtration 25 complémentaire est évité.An additional advantage of a vacuum cleaner according to the present invention resides in the installation of the waterproof bag 20 in the tank 3. The user places the bag 20 in the tank 3 and begins to deploy it against the walls. Thus the major drawback of seeing the bag 20 driven against the complementary filtration means 25 by the air flow 12 before it is deployed under the effect of the vacuum created by the air flow 12 passing through the additional filtration means 25 is avoided.
Un avantage considérable d'un aspirateur conforme à la présente invention réside dans le coût de fabrication très bas du sac etanche 20 et du moyen de filtration 25 complémentaire, car il n'y a pas de manipulation particulière à faire sur le sac, ni de coût d'assemblage.A considerable advantage of a vacuum cleaner according to the present invention lies in the very low manufacturing cost of the waterproof bag 20 and the additional filtration means 25, since there is no particular handling to be done on the bag, nor cost of assembly.
Un autre avantage d'un aspirateur conforme à la présente invention réside dans la possibilité d'utiliser un sac etanche 20 quelconque d'une capacité en relation avec celle de la cuve 3, sans être obligé de se procurer un sac spécifiquement conçu pour cet aspirateur.Another advantage of a vacuum cleaner according to the present invention lies in the possibility of using any waterproof bag 20 of any capacity in relation to that of the tank 3, without being obliged to obtain a bag specifically designed for this vacuum cleaner .
Un autre avantage de l'invention et en particulier du sac etanche 20 conforme à l'invention réside dans la première filtration que l'on obtient à l'aide du moyen de filtration 25 complémentaire et par conséquent dans l'augmentation de la durée de vie du filtre 2a associé au système d'aspiration 2. Ceci a aussi pour conséquence d'accentuer la purification du flux d'air expulsé 13. Un autre avantage dans l'utilisation du sac etanche 20 conforme à l'invention réside dans le confinement des déchets aspirés, qu'il procure à l'utilisateur. Le sac etanche 20 peut être aisément dégagé de la cuve 3 sans risque de répandre à l'extérieur une quantité plus au moins importante de poussière aspirée.Another advantage of the invention and in particular of the waterproof bag 20 according to the invention lies in the first filtration which is obtained with the aid of the complementary filtration means 25 and consequently in the increase in the duration of life of the filter 2a associated with the suction system 2. This also has the effect of accentuating the purification of the flow of expelled air 13. Another advantage in the use of the waterproof bag 20 according to the invention lies in the confinement of the sucked-in waste, which it provides to the user. The waterproof bag 20 can be easily disengaged from the tank 3 without the risk of spreading outside a more or less large amount of dust sucked.
Un autre avantage de l'aspirateur conforme à la présente invention réside dans sa sécurité d'utilisation, en effet si par accident le sac etanche 20 présente une déchirure à l'intérieur de la cuve 3, les déchets aspirés hors de ladite cuve 3 à travers la prise de pression 5, seront arrêtés par le filtre 2a et ne pourront pas pénétrer directement dans le logement du moteur 2c et détériorer ce dernier.Another advantage of the vacuum cleaner according to the present invention lies in its safety in use, in fact if by accident the waterproof bag 20 has a tear inside the tank 3, the waste sucked out of said tank 3 to through the pressure tap 5, will be stopped by the filter 2a and will not be able to penetrate directly into the housing of the engine 2c and damage the latter.
Un autre avantage de l'aspirateur conforme à la présente invention réside dans l'utilisation d'un moyen de filtration 25 complémentaire comportant au moins deux couches 30, 31. La couche 30, plus épaisse que la couche 31 , et traversée avant ladite couche 31 par le flux d'air aspiré 12, retarde le colmatage de ladite couche 31 par les fines particules.Another advantage of the vacuum cleaner according to the present invention lies in the use of an additional filtration means 25 comprising at least two layers 30, 31. The layer 30, thicker than the layer 31, and passed through before said layer 31 by the suction air flow 12, delays the clogging of said layer 31 by fine particles.
Un autre avantage complémentaire de l'aspirateur conforme à l'invention réside dans le positionnement du moyen de filtration 25 complémentaire. Ce positionnement en partie supérieure de la cuve 3 est intéressant dans la mesure où toute vibration transmise à l'aspirateur, par exemple lors de son déplacement, est transmise au moyen de filtration 25 complémentaire lequel peut se défaire ainsi de poussières colmatées sur sa paroi communiquant avec le volume interne 21.Another additional advantage of the vacuum cleaner according to the invention lies in the positioning of the complementary filtration means. This positioning in the upper part of the tank 3 is advantageous insofar as any vibration transmitted to the vacuum cleaner, for example during its movement, is transmitted by additional filtration means which can thus get rid of clogged dust on its communicating wall with internal volume 21.
Un avantage supplémentaire de la présente invention réside dans l'obtention d'une cuve 3 propre malgré l'aspiration de déchets tels que de l'eau ou de l'huile ou tout autre liquide répandu sur une surface à nettoyer. Tous ces déchets restent confinés dans le sac etanche 20.An additional advantage of the present invention lies in obtaining a clean tank 3 despite the suction of waste such as water or oil or any other liquid spilled on a surface to be cleaned. All this waste remains confined in the waterproof bag 20.
Un autre avantage de l'aspirateur conforme à la présente invention réside dans l'utilisation de l'appareil avec le moyen de filtration 25 complémentaire sans mettre de sac dans la cuve 3, pour aspirer une grande quantité d'eau.Another advantage of the vacuum cleaner according to the present invention lies in the use of the apparatus with the complementary filtration means 25 without putting a bag in the tank 3, to suck up a large amount of water.
Un autre avantage de l'aspirateur conforme à la présente invention réside dans l'utilisation d'une platine 33 dans laquelle est inséré le moyen de filtration 25 complémentaire, rendant ainsi le positionnement du moyen de filtration 25 complémentaire sur la cuve 3 plus facile.Another advantage of the vacuum cleaner according to the present invention lies in the use of a plate 33 in which is inserted the complementary filtration means 25, thus making the positioning of the complementary filtration means 25 on the tank 3 easier.
Un autre avantage de la présente invention réside dans l'utilisation d'un moyen de filtration 25 complémentaire lavable et réutilisable, avec ou sans sac collecteur de déchets. Another advantage of the present invention lies in the use of a washable and reusable complementary filtration means, with or without a waste collection bag.
