Description

DISPOSITIF DE NETTOYAGE PAR ASPIRATION SUCTION CLEANING DEVICE
La présente , invention concerne un perfectionnement aux dispositifs de nettoyage de tapis, moquettes ou analogues par aspiration comprenant une buse d'aspiration constituée d'un manche tubulaire connecté par un conduit flexible à une source de dépression et d'une tête d'aspiration globalement cylindrique délimitant une chambre d'aspiration dans laquelle débouche un tube d'arrivée de fluide à compression réglable.The present invention relates to an improvement to devices for cleaning carpets, rugs or the like by suction comprising a suction nozzle consisting of a tubular handle connected by a flexible conduit to a source of vacuum and a suction head overall. cylindrical delimiting a suction chamber into which opens a fluid inlet tube with adjustable compression.
Dans le domaine des dispositifs de nettoyage par aspiration, on connaît bien des dispositifs d'aspiration de poussière et de fines particules comprenant une tête d'aspiration, un tuyau reliant la tête d'aspiration et une unité d'aspiration pour aspirer les poussières et les fines particules de la tête vers l'unité d'aspiration, et un conduit pour amener un gaz provenant d'une source de gaz sous pression dans la tête d'aspiration ; c'est le cas, par exemple, du brevet belge BE 1.011.863 décrivant un dispositif d'aspiration et un procédé d'aspiration. Le dispositif comprend une tête d'aspiration, un tuyau reliant la tête d'aspiration à une unité d'aspiration et un conduit pour amener un gaz sous pression dans ladite tête d'aspiration, ledit gaz sous pression provenant d'une bonbonne de gaz comprimé, d'un compresseur d'air, d'un appareil pour former de la vapeur sous pression ou analogue. Le conduit débouche dans un distributeur de gaz sous pression comportant deux branches parallèles entre- elles s'étendant à l'intérieur de la tête d'aspiration à proximité de son bord et présentant chacune une série d'orifices. Les branches sont prolongées par des pattes latérales présentant chacune un orifice agencé pour souffler les poussières soulevées vers l'orifice d'aspiration du tuyau positionné au centre de ladite tête d'aspiration.In the field of vacuum cleaning devices, dust and fine particle suction devices are well known, comprising a suction head, a pipe connecting the suction head and a suction unit for vacuuming dust and fine particles from the head to the suction unit, and a conduit for supplying gas from a source of pressurized gas into the suction head; this is the case, for example, of the Belgian patent BE 1,011,863 describing a suction device and a suction process. The device comprises a suction head, a pipe connecting the suction head to a suction unit and a conduit for bringing a pressurized gas into said suction head, said pressurized gas coming from a gas cylinder compressed, air compressor, apparatus for forming pressurized steam or the like. The duct opens into a pressurized gas distributor comprising two mutually parallel branches extending inside the suction head near its edge and each having a series of orifices. The branches are extended by lateral tabs each having an orifice arranged for blowing the dust raised towards the suction orifice of the pipe positioned at the center of said suction head.
Dès lors que la pression du gaz comprimé est supérieure à la dépression créée dans la tête d'aspiration, le gaz sortant des orifices des branches du distributeur de gaz, bien que soulevant les poussières, insectes, animaux microscopiques, etc .. situés entre les poils d'un tapis par exemple, crée une surpression de l'air dans le tête d'aspiration à proximité de la surface à traiter, un tapis en l'occurrence, de sorte que la tête d'aspiration se comporte comme si elle était bouchée, créant ainsi un phénomène de succion, c'est-à-dire qu'une dépression règne dans la chambre d'aspiration sans qu'il y ait de déplacement d'air, empêchant ainsi l'aspiration desdites poussières soulevées par le gaz sortant des orifices .As soon as the pressure of the compressed gas is higher than the vacuum created in the suction head, the gas leaving the orifices of the branches of the distributor gas, although raising dust, insects, microscopic animals, etc. located between the hairs of a carpet for example, creates an air pressure in the suction head near the surface to be treated, a carpet in this case, so that the suction head behaves as if it were blocked, thus creating a phenomenon of suction, that is to say that a vacuum prevails in the suction chamber without it there is displacement of air, thus preventing the aspiration of said dust raised by the gas leaving the orifices.
L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant un dispositif pour le nettoyage de tapis, moquettes ou analogues comprenant des moyens de projection d'un jet de fluide comprimé à l'intérieur de la chambre d'aspiration d'une buse d'aspiration de conception simple et ne perturbant pas le vortex de l'aspiration.One of the aims of the invention is therefore to remedy these drawbacks by proposing a device for cleaning carpets, rugs or the like, comprising means for projecting a jet of compressed fluid inside the chamber. suction of a suction nozzle of simple design and not disturbing the vortex of the suction.
A cet effet et conformément à l'invention, il est proposé un dispositif pour le nettoyage de tapis, moquettes ou analogues par aspiration comprenant une buse d'aspiration constituée d'un manche tubulaire connecté par un conduit flexible à une source de dépression et d'une tête d'aspiration globalement cylindrique, dont l'axe est vertical lorsque la tête d'aspiration est au contact d'un sol horizontal, délimitant une chambre d'aspiration dans laquelle débouche un tube connecté à une source de fluide comprimé ; ledit dispositif est remarquable en ce que le tube d'arrivée de fluide comprimé consiste dans un tube capillaire s ' étendant globalement parallèlement au manche tubulaire et débouchant dans la chambre d'aspiration en formant un angle compris entre 5 et 50° par rapport à l'axe de la tête d'aspiration, ledit tube capillaire s'étendant depuis la partie supérieure de la paroi de la tête d'aspiration jusqu'à la partie médiane de ladite tête de telle sorte que le fluide comprimé soit projeté au centre de la surface à traiter délimitée par la tête d'aspiration et en ce que ladite tête d'aspiration comprend au moins un trou d'arrivée d'air afin de ne pas perturber le vortex de l'aspiration lorsque le fluide comprimé est projeté dans la chambre d'aspiration par le tube capillaire.To this end and in accordance with the invention, there is provided a device for cleaning carpets, rugs or the like by suction comprising a suction nozzle consisting of a tubular handle connected by a flexible conduit to a source of vacuum and d 'a generally cylindrical suction head, the axis of which is vertical when the suction head is in contact with a horizontal floor, delimiting a suction chamber into which opens a tube connected to a source of compressed fluid; said device is remarkable in that the compressed fluid inlet tube consists of a capillary tube extending generally parallel to the tubular handle and opening into the suction chamber at an angle between 5 and 50 ° relative to the the axis of the suction head, said capillary tube extending from the upper part of the wall of the suction head to the middle part of said head so that the compressed fluid is projected in the center of the surface to be treated bounded by the suction head and in that said suction head comprises at least one air intake hole so as not to disturb the vortex of suction when the compressed fluid is projected into the suction chamber by the capillary tube.
On comprend bien que le trou d' arrivée d' air dans la tête d'aspiration permet de maintenir une aspiration globalement constante dans la tête d'aspiration du dispositif de sorte que, dans un premier temps, les poussières sont soulevées de la surface à traiter et, dans un second temps, ces dernières sont aspirées.It is understood that the air inlet hole in the suction head makes it possible to maintain a generally constant suction in the suction head of the device so that, initially, the dust is lifted from the surface to process and, in a second step, these are aspirated.
Selon une caractéristique particulièrement avantageuse du dispositif conforme à l'invention, ce dernier comprend des moyens de commande de 1 ' arrivée du fluide comprimé dans le tube capillaire solidaire du premier tube du manche, ces moyens de commande étant constitués d'une gâchette actionnant une pointe qui coulisse dans un corps creux connecté au tube capillaire et à la source de fluide comprimé de telle sorte que ladite pointe obstrue partiellement ou intégralement ou bien encore laisse libre l'arrivée du fluide comprimé dans le corps creux afin de régler le débit dudit fluide à la sortie du tube capillaire.According to a particularly advantageous characteristic of the device according to the invention, the latter comprises means for controlling the arrival of the compressed fluid in the capillary tube integral with the first tube of the handle, these control means being constituted by a trigger actuating a tip which slides in a hollow body connected to the capillary tube and to the source of compressed fluid so that said tip partially or completely obstructs or even leaves free the arrival of the compressed fluid in the hollow body in order to regulate the flow of said fluid at the outlet of the capillary tube.
D'autres avantages et caractéristiques ressortiront mieux de la description qui va suivre de plusieurs variantes d'exécution du dispositif de nettoyage par aspiration, données à titre d'exemples non limitatifs, à partir des dessins annexés sur lesquels :Other advantages and characteristics will emerge more clearly from the description which follows of several alternative embodiments of the suction cleaning device, given by way of nonlimiting examples, from the appended drawings in which:

- la figure 4 est une vue en coupe longitudinale schématique du dispositif conforme à l'invention.- Figure 4 is a schematic longitudinal sectional view of the device according to the invention.
En référence aux figures, le dispositif de nettoyage par aspiration qui va* être décrit à titre d'exemple non limitatif est particulièrement destiné au nettoyage de tapis, de moquette, de tissus ou des "plastiques" des équipements intérieurs d'une voiture notamment. A cet égard, on a représenté sur la figure 1 une vue générale du dispositif comprenant une buse d'aspiration 1 constituée d'un manche tubulaire 2 connecté par un conduit flexible 3 à une source de dépression 4, telle qu'un aspirateur par exemple, et d'une tête d'aspiration 5 globalement cylindrique délimitant une chambre d'aspiration dans laquelle débouche un tube d'arrivée de fluide comprimé 6 connecté à une source de fluide comprimé 7 par un tuyau flexible 8, comme il sera détaillé plus loin. La source de fluide comprimé 7 consiste avantageusement dans un compresseur d'air comprimé délivrant de l'air comprimé à une pression supérieure à 2 bars.Referring to the figures, the cleaning device by suction which will * be described by way of nonlimiting example is particularly intended for cleaning carpets, rugs, fabrics or "plastics" of interior equipment of a car in particular. In this regard, there is shown in Figure 1 a general view of the device comprising a suction nozzle 1 consisting of a tubular handle 2 connected by a flexible conduit 3 to a vacuum source 4, such as a vacuum cleaner for example , and a generally cylindrical suction head 5 delimiting a suction chamber into which opens a compressed fluid inlet tube 6 connected to a source of compressed fluid 7 by a flexible pipe 8, as will be detailed below. . The source of compressed fluid 7 advantageously consists of a compressed air compressor delivering compressed air at a pressure greater than 2 bars.
Il va de soi que, le fluide peut consister dans n'importe quel type de fluide tel que de l'eau, de l'eau savonneuse, ou dans un gaz tel que de la vapeur d'eau par exemple, sans pour autant sortir du cadre de l'invention.It goes without saying that, the fluid can consist of any type of fluid such as water, soapy water, or in a gas such as steam, for example, without leaving of the scope of the invention.
Selon une première variante d'exécution du dispositif conforme à l'invention, en référence à la figure 2, la tête d'aspiration 5 de la buse 1 consiste dans un anneau 9 globalement cylindrique muni sur son bord inférieur de faisceaux de poils 10 s'étendant dans le prolongement de la génératrice de l'anneau 9 et délimitant une chambre d'aspiration 11 dans laquelle débouche un tube d'arrivée de fluide comprimé 6. Le tube d'arrivée du fluide comprimé consiste dans un tube capillaire s'étendant globalement parallèlement au manche tubulaire 2 et débouchant dans la chambre d'aspiration 11 par un trou 12 pratiqué dans l'anneau 9 de la tête d'aspiration 5 en formant un angle α compris entre 5 et 50°, et de préférence aux environs de 45°, par rapport à l'axe A de la tête d'aspiration 5, ledit axe A s ' étendant globalement verticalement lorsque la tête d'aspiration 5 est au contact d'un sol horizontal. On entend par tube capillaire 6 un tube présentant une section circulaire d'un diamètre compris entre 1 et 5 mm ; toutefois, ce tube capillaire 6 peut présenter une section oblongue ou rectangulaire sans nuire à son efficacité. Par ailleurs, le tube capillaire 6 s'étend depuis la partie supérieure de la paroi de la tête d'aspiration 5, constituée par l'anneau 9 et les faisceaux de poils 10, jusqu'à la partie médiane de ladite tête 5 de telle sorte que le fluide comprimé soit projeté au centre de la surface à traiter délimitée par la tête d'aspiration 5 comme l'indique les flèches a sur la figure 2. Par ailleurs, les faisceaux de poils 10 sont évasés dans leur partie inférieure et sont espacés autour de 1 ' anneau 9 pour former à proximité dudit anneau 9 des ouvertures 13 dites "trou d'arrivée d'air" permettant un écoulement d'air dans la chambre d'aspiration 11. Ces trous d'arrivée d'air 13 sont avantageusement situés au dessus de l'extrémité libre du tube capillaire 6 afin de ne pas perturber le vortex de 1 ' aspiration lorsque le fluide comprimé est projeté dans la chambre d'aspiration 11.According to a first alternative embodiment of the device according to the invention, with reference to FIG. 2, the suction head 5 of the nozzle 1 consists of a generally cylindrical ring 9 provided on its lower edge with bundles of bristles 10 s extending in the extension of the generator of the ring 9 and delimiting a suction chamber 11 into which opens a compressed fluid inlet tube 6. The compressed fluid inlet tube consists of a capillary tube extending generally parallel to the tubular handle 2 and opening into the suction chamber 11 through a hole 12 made in the ring 9 of the suction head 5 by forming an angle α between 5 and 50 °, and preferably around 45 °, relative to the axis A of the suction head 5, said axis A extending generally vertically when the suction head 5 is in contact with a horizontal ground. By capillary tube 6 is meant a tube having a circular section with a diameter between 1 and 5 mm; however, this capillary tube 6 can have an oblong or rectangular section without affecting its effectiveness. Furthermore, the capillary tube 6 extends from the upper part of the wall of the suction head 5, constituted by the ring 9 and the bristle bundles 10, to the middle part of said head 5 of such so that the compressed fluid is projected into the center of the surface to be treated delimited by the suction head 5 as indicated by the arrows a in FIG. 2. Furthermore, the hair bundles 10 are flared in their lower part and are spaced around the ring 9 to form near said ring 9 openings 13 called "air intake hole" allowing air flow in the suction chamber 11. These air intake holes 13 are advantageously located above the free end of the capillary tube 6 so as not to disturb the vortex of the suction when the compressed fluid is sprayed into the suction chamber 11.
Selon une autre variante d'exécution du dispositif conforme à l'invention, en référence à la figure 4, la tête d'aspiration 5 consiste dans un tube 14 globalement cylindrique obtenu dans une matière plastique formant la chambre d'aspiration 11. Le tube 14 présente un trou d'arrivée d'air 15 positionné au dessus de l'extrémité libre du tube capillaire 6, ledit tube capillaire 6 débouchant dans la chambre d'aspiration par un trou 12 formé dans la paroi de la tête d'aspiration 5 en formant un angle α compris entre 5 et 50° par rapport à l'axe A de la tête d'aspiration 5 et s'étendant depuis la partie supérieure de la paroi de la tête d'aspiration 5 jusqu'à la partie médiane de cette dernière de telle sorte que le fluide comprimé soit projeté au centre de la surface à traiter délimitée par la tête d'aspiration 5 comme l'indique les flèches b. Le trou d'arrivée d'air 15' de la tête d'aspiration 5 est diamétralement opposé au trou 12 pratiqué dans la paroi de la tête d'aspiration 5 par lequel le tube capillaire 6 débouche dans la chambre d'aspiration 11. Le Déposant a ainsi remarqué qu'une telle configuration de la tête d'aspiration 5 procure une meilleure aspiration que la tête d'aspiration 5 munie de faisceaux de poils 10 décrite précédemment.According to another alternative embodiment of the device according to the invention, with reference to FIG. 4, the suction head 5 consists of a generally cylindrical tube 14 obtained from a plastic material forming the suction chamber 11. The tube 14 has an air inlet hole 15 positioned above the free end of the capillary tube 6, said capillary tube 6 opening into the suction chamber through a hole 12 formed in the wall of the suction head 5 by forming an angle α of between 5 and 50 ° relative to the axis A of the suction head 5 and extending from the upper part of the wall of the suction head 5 to the middle part of the latter so that the compressed fluid is projected into the center of the surface to be treated bounded by the suction head 5 as indicated by the arrows b. The air inlet hole 15 ′ of the suction head 5 is diametrically opposite the hole 12 made in the wall of the suction head 5 through which the capillary tube 6 opens into the suction chamber 11. The The depositor thus noticed that such a configuration of the suction head 5 provides better suction than the suction head 5 provided with bristle bundles 10 described above.
Il est bien évident que la tête d'aspiration 5 peut comprendre plusieurs trous d'arrivée d'air 15 et que le nombre et le diamètre de ces trous d'arrivée d'air 15 dépendent notamment de la pression du gaz comprimé et de la force d'aspiration.It is obvious that the suction head 5 can comprise several air inlet holes 15 and that the number and the diameter of these air inlet holes 15 depend in particular on the pressure of the compressed gas and on the suction force.
En référence à la figure 4, le manche 2 de la buse d'aspiration 1 est constituée de deux tubes cylindriques, un premier tube 2a connecté par le conduit flexible 3 à la source de dépression 4 (fig. 1) et un second tube 2b de diamètre supérieur au premier tube 2a connecté à la tête d'aspiration 5 de telle sorte que le premier tube 2a s'emboîte en force dans le second tube 2b. La partie du tube capillaire 6 s'étendant le long du manche 2 comprend, par ailleurs, des moyens de raccordement 16 munis d'un joint d'étanchéité 17, tels que par exemple un raccord union classiquement constitué d'un raccord mâle avec écrou de serrage coopérant avec un raccord femelle et une rondelle de fibre, afin de permettre le changement de la tête d'aspiration 5 à l'extrémité du manche 2 en fonction du type de surface à traiter. En effet, la tête d'aspiration 5 munie de faisceaux de poils 10 formant une brosse, représentée sur la figure 2, est de préférence utilisée pour le nettoyage de surfaces lisses telles que les équipements "plastiques" d'un véhicule ou des sols carrelés par exemple, et la tête d'aspiration 5 constituée d'un tube cylindrique 14 obtenu dans une matière plastique, représentée sur la figure 3, est de préférence utilisée pour des surfaces rugueuses telles que des moquettes, des tapis ou des tissus ; toutefois, il est bien évident que les têtes d'aspiration 5 peuvent être changées à la convenance de l'utilisateur. Par ailleurs, le premier tube 2a du manche 2 comprend avantageusement sur sa paroi externe à proximité de son extrémité libre un ergot 18a s'étendant radialement et coopérant avec un creux correspondant 18b du bord de l'extrémité libre du second tube 2b, c'est-à-dire à son bord opposé à la tête d'aspiration 5, afin d'empêcher la rotation de ladite tête d ' aspiration 5 autour de 1 ' axe du manche 2. Afin de régler le débit du fluide à la sortie du tube capillaire 6, le dispositif comprend avantageusement des moyens de commande 19 de l'arrivé du fluide comprimé dans le tube capillaire 6, lesdits moyens de commande 19 solidaires du premier tube 2a du manche 2 qui constitue une zone de préhension préférée de la buse 1. Les moyens de commande 19 de l'arrivée du fluide comprimé sont constitués d'un corps creux 20 solidarisé au premier tube 2a du manche 2 par un collier de fixation 21, ledit corps creux 20 étant connecté au tube capillaire 6 et à la source de fluide comprimé 7 par le tuyau flexible 8. Lesdits moyens de commande 19 comprennent, par ailleurs, une gâchette 22 actionnant une pointe 23 qui coulisse dans le corps creux 20 de telle sorte que ladite pointe 23 obstrue partiellement ou intégralement ou bien encore laisse libre l'arrivée du fluide comprimé dans le corps creux 20 afin de régler le débit dudit fluide à la sortie du tube capillaire 6.Referring to Figure 4, the handle 2 of the suction nozzle 1 consists of two cylindrical tubes, a first tube 2a connected by the flexible conduit 3 to the vacuum source 4 (fig. 1) and a second tube 2b of diameter greater than the first tube 2a connected to the suction head 5 so that the first tube 2a is forced into the second tube 2b. The part of the capillary tube 6 extending along the handle 2 further comprises connection means 16 provided with a seal 17, such as for example a union fitting conventionally consisting of a male fitting with nut clamping cooperating with a female connector and a fiber washer, to allow the change of the suction head 5 at the end of the handle 2 depending on the type of surface to be treated. Indeed, the suction head 5 provided with bristle bundles 10 forming a brush, shown in FIG. 2, is preferably used for cleaning smooth surfaces such as the "plastic" equipment of a vehicle or tiled floors for example, and the suction head 5 consisting of a cylindrical tube 14 obtained in a plastic material, shown in Figure 3, is preferably used for rough surfaces such as carpets, rugs or fabrics; however, it is obvious that the suction heads 5 can be changed at the convenience of the user. Furthermore, the first tube 2a of the handle 2 advantageously comprises on its outer wall near its free end a lug 18a extending radially and cooperating with a corresponding recess 18b of the edge of the free end of the second tube 2b, that is to say at its edge opposite the suction head 5, in order to prevent the rotation of said suction head 5 around the axis of the handle 2. In order to adjust the flow rate of the fluid at the outlet of the capillary tube 6, the device advantageously comprises control means 19 for the arrival of the compressed fluid in the capillary tube 6, said control means 19 integral with the first tube 2a of the handle 2 which constitutes a preferred gripping area of the nozzle 1. The control means 19 for the arrival of the compressed fluid consist of a hollow body 20 secured to the first tube 2a of the handle 2 by a fixing collar 21, said hollow body 20 being connected to the capillary tube 6 and to the source of compressed fluid 7 by the flexible pipe 8. Said control means 19 furthermore comprise a trigger 22 actuating a tip 23 which slides in the hollow body 20 so that said point 23 obstructs pa completely or completely or else leaves free the arrival of the compressed fluid in the hollow body 20 in order to regulate the flow rate of said fluid at the outlet of the capillary tube 6.
Enfin, il va de soi que le dispositif selon 1 ' invention peut être adapté à tous les types de tête d'aspiration tels qu'une tête d'aspiration rectangulaire par exemple et que les exemples que 1 ' on vient de donner ne sont que des illustrations particulières en aucun cas limitatives quant au domaine d'application de l'invention. Finally, it goes without saying that the device according to the invention can be adapted to all types of suction head such as a rectangular suction head for example and that the examples that have just been given are only particular illustrations which in no way limit the scope of the invention.
