Description

La présente invention est relative aux dispositifs d'aspiration avec raclette qui sont susceptibles d'être adaptés au bout d'un manche de manoeuvre ou d'une poignée de préhension, afin d'éliminer l'eau sale lors du nettoyage de certaines surfaces. Les dispositifs de ce genre comportent à la fois une raclette élastique et des orifices ou canaux d'aspiration permettant d'aspirer le liquide de nettoyage répandu auparavant sur la surface à nettoyer, et ce au moyen d'une pompe raccordée à un réservoir de collecte.The present invention relates to suction devices with a squeegee which are capable of being adapted at the end of an operating handle or a grip handle, in order to eliminate the dirty water when cleaning certain surfaces. Devices of this type include both an elastic squeegee and suction orifices or channels allowing the suction of the cleaning liquid previously spilled on the surface to be cleaned, by means of a pump connected to a collection tank. .

Une tête de nettoyage ainsi équipée est décrite dans le brevet FR 2.485.405. Cette tête comporte à la fois un patin perméable d'épandage d'un liquide de nettoyage et des raclettes disposées sur l'une et l'autre faces frontales avant et arrière de cette tête, ainsi que des orifices d'aspiration prévus en regard de l'une et l'autre de ces raclettes. Lors du déplacement de cette tête de nettoyage sur la surface à nettoyer, la raclette située en arrière pousse devant elle le liquide précédemment répandu sur cette surface afin que ce dernier soit aspiré à travers les orifices d'aspiration correspondants. En effet, cette tête de nettoyage est en principe conçue de façon que la raclette en service ne laisse subsister, sur la surface traitée, qu'un film liquide susceptible de disparaitre rapidement par séchage.A cleaning head thus equipped is described in patent FR 2,485,405. This head comprises both a permeable pad for spreading a cleaning liquid and squeegees arranged on both of the front and rear front faces of this head, as well as suction orifices provided facing both of these squeegees. During the movement of this cleaning head on the surface to be cleaned, the squeegee located behind pushes the liquid previously spilled on this surface in front of it so that the latter is sucked through the corresponding suction orifices. In fact, this cleaning head is in principle designed so that the squeegee in use leaves only a liquid film which can disappear quickly on drying on the treated surface.

Toutefois, les conditions réelles de fonctionnement d'une telle tête de nettoyage ne sont pas pleinement satisfaisantes et ne permettent pas d'obtenir le résultat recherché. En particulier l'efficacité de l'aspiration du liquide à éliminer est insuffisante. Ceci est principalement dû au fait que les orifices d'aspiration sont situés à une distance trop importante de l'arête de contact de la raclette avec la surface à traiter.However, the actual operating conditions of such a cleaning head are not fully satisfactory and do not allow the desired result to be obtained. In particular, the efficiency of the suction of the liquid to be eliminated is insufficient. This is mainly due to the fact that the suction orifices are located at too great a distance from the contact edge of the squeegee with the surface to be treated.

C'est pourquoi, la présente invention a pour but de réaliser un dispositif de raclette aspirante conçu de façon que l'aspiration du liquide de nettoyage s'effectue avec le maximum d'efficacité.This is why, the present invention aims to provide a suction scraper device designed so that the suction of the cleaning liquid is carried out with maximum efficiency.

A cet effet, le dispositif selon l'invention est essentiellement caractérisé en ce que :
- sa raclette consiste en une lame en matière élastique à l'intérieur de laquelle sont ménagés des canaux d'aspiration débouchant sur l'une au moins des deux faces de cette raclette par des orifices alignés parallèlement à l'arête inférieure correspondante de cette raclette et à proximité de celle-ci,
- sur les canaux d'aspiration ainsi prévus sont branchées des conduites flexibles aboutissant à une pompe à galets, raccordée par ailleurs à un réservoir de collecte du liquide sale de nettoyage à éliminer.To this end, the device according to the invention is essentially characterized in that:
- Its squeegee consists of a blade of elastic material inside which are provided suction channels opening on at least one of the two faces of this squeegee by orifices aligned parallel to the corresponding lower edge of this squeegee and close to it,
- flexible suction lines are connected to the suction channels thus provided, leading to a roller pump, which is also connected to a reservoir for collecting the dirty cleaning liquid to be eliminated.

Du fait même de la conception particulière de la raclette prévue dans le dispositif selon l'invention, l'aspiration du liquide à éliminer est réalisée dans des conditions optimum d'efficacité. Ceci permet donc effectivement de ne laisser subsister qu'un film extrêmement mince de liquide sur la surface à nettoyer, lequel est susceptible de disparaître ensuite rapidement par séchage.Due to the particular design of the squeegee provided in the device according to the invention, the suction of the liquid to be removed is carried out under optimum conditions of efficiency. This therefore effectively makes it possible to leave only an extremely thin film of liquid on the surface to be cleaned, which is liable to disappear quickly after drying.

Il convient de noter que la présente invention a également pour objet la raclette de conception particulière qui est destinée à équiper le dispositif de nettoyage tel que défini ci-dessus.It should be noted that the present invention also relates to the squeegee of a particular design which is intended to equip the cleaning device as defined above.

Dans une forme particulière de réalisation de ce dispositif, celui-ci comporte en outre une brosse ou autre organe apte à assurer l'épandage d'un liquide de nettoyage provenant d'un réservoir raccordé à cet organe d'épandage par une ou plusieurs conduites d'alimentation.In a particular embodiment of this device, it further comprises a brush or other member capable of ensuring the spreading of a cleaning liquid coming from a reservoir connected to this spreading member by one or more pipes. power supply.

Dans la forme de réalisation représentée aux figures 1 à 4, le dispositif de nettoyage selon l'invention comporte une raclette 1 en matière élastique dont l'un des bords longitudinaux est fixé sur un carter rigide 2 de forme allongée. En son centre, celui-ci comporte un manchon 3 destiné à recevoir un manche de manoeuvre 4 ou éventuellement une poignée de préhension. Dans le premier cas, le présent dispositif peut être utilisé pour effectuer le nettoyage d'un sol lisse, par exemple en carrelage ou limilaire, cependant que dans le second cas il peut être employé pour le nettoyage de toutes autres surfaces lisses, par exemple des vitres ou des parois verticales, etc.In the embodiment shown in Figures 1 to 4, the cleaning device according to the invention comprises a squeegee 1 of elastic material, one of the longitudinal edges of which is fixed to a rigid casing 2 of elongated shape. At its center, it includes a sleeve 3 intended to receive an operating handle 4 or possibly a grip handle. In the first case, the present device can be used to carry out the cleaning of a smooth floor, for example in tiling or limestone, while in the second case it can be used for the cleaning of all other smooth surfaces, for example panes or vertical walls, etc.

La raclette 4 est constituée par une bande plate de forme rectangulaire, fabriquée en matière élastique, par exemple en caoutchouc naturel ou synthétique, ou bien encore en matière plastique. Conformément à l'invention une série de canaux 5 d'aspiration sont ménagés dans l'épaisseur même du corps de la raclette 1, ces canaux s'étendant parallèlement au deux grandes faces de cette raclette. A l'extrémité 6 de celle-ci, qui est tournée du côté opposé au carter 2, les canaux 5 sont coudés alternativement vers l'une et l'autre des deux grandes faces de cette raclette et ils débouchent à l'extérieur par des orifices 7. Ceux-ci se trouvent situés à proximité immédiate de l'une ou l'autre arête 8 de la raclette qui se trouve au contact du sol, suivant que celle-ci est inclinée dans un sens ou dans l'autre (voir figure 4). Ces orifices sont alignés parallèlement à l'arête 8 voisine.The squeegee 4 is formed by a flat strip of rectangular shape, made of elastic material, for example natural or synthetic rubber, or even plastic. According to the invention, a series of suction channels 5 are formed in the very thickness of the body of the squeegee 1, these channels extending parallel to the two large faces of this squeegee. At the end 6 of the latter, which is turned on the side opposite to the casing 2, the channels 5 are bent alternately towards one and the other of the two large faces of this squeegee and they open to the outside by orifices 7. These are located in the immediate vicinity of one or other edge 8 of the squeegee which is in contact with the ground, depending on whether the latter is inclined in one direction or the other (see figure 4). These orifices are aligned parallel to the neighboring edge 8.

Sur le chant opposé de la raclette 1, les canaux d'aspiration 5 se terminent par des orifices de sortie 9 sur chacun desquels est branchée une conduite flexible 10 d'aspiration. Les différentes conduites ainsi prévues aboutissent à une pompe à galets désignée par la référence générale 11. Ces conduites sont réparties en deux groupes distincts disposés de part et d'autre du rotor 12 de cette pompe, de façon à être écrasés par les galets 13 portés par ce rotor, ce qui assure l'aspiration du liquide à éliminer sans risque de désamorçage de la pompe. A leurs extrémités terminales, les conduites 10 sont raccordées à des canalisations 14 aboutissant à un réservoir destiné à recueillir le liquide sale de nettoyage, ce réservoir étant susceptible d'être vidé périodiquement. Comme représenté sur les figures 1 et 2, le réservoir 15 et la pompe 11 sont disposés de part et d'autre du manchon 3 dans le sens de la longueur du carter 2. Ces deux éléments sont du reste fixés ou inclus dans le carter. Il en est de même pour le moteur électrique 16 d'entraînement du rotor de la pompe 11, ainsi que pour les accumulateurs rechargeables assurant l'alimentation de ce moteur en courant électrique.On the opposite edge of the squeegee 1, the suction channels 5 terminate in outlet orifices 9 to each of which is connected a flexible suction pipe 10. The various pipes thus provided lead to a roller pump designated by the general reference 11. These pipes are divided into two groups separate arranged on either side of the rotor 12 of this pump, so as to be crushed by the rollers 13 carried by this rotor, which ensures the suction of the liquid to be removed without risk of defusing the pump. At their terminal ends, the pipes 10 are connected to pipes 14 leading to a reservoir intended to collect the dirty cleaning liquid, this reservoir being capable of being emptied periodically. As shown in Figures 1 and 2, the reservoir 15 and the pump 11 are arranged on either side of the sleeve 3 in the lengthwise direction of the casing 2. These two elements are moreover fixed or included in the casing. It is the same for the electric motor 16 for driving the rotor of the pump 11, as well as for the rechargeable accumulators ensuring the supply of this motor with electric current.

Le dispositif de nettoyage ainsi constitué est destiné à être appliqué sur la surface à traiter après nettoyage de celle-ci, au moyen d'un liquide de nettoyage approprié, ce liquide pouvant être épandu de toutes façons voulues. L'application du présent dispositif a pour but d'éliminer le liquide se trouvant sur le sol correspondant S de façon à ne laisser subsister qu'un mince film liquide susceptible de disparaître rapidement par séchage. A cet effet, il convient de faire glisser la raclette 1 sur le sol en disposant l'ensemble dans la position inclinée représentée sur la figure 4. La raclette se trouve alors en contact du sol par son arête inférieure 8 située vers l'avant. Dans ces conditions, cette arête repousse devant elle le liquide de nettoyage répandu sur le sol, de sorte que celui-ci est immédiatement aspiré à travers les orifices 7 situés sur la face avant de la raclette. Etant donné que les canaux d'aspiration sont ménagés à l'intérieur même de la raclette et que leurs orifices d'entrée 7 débouchent à proximité immédiate de l'arête 8 en position de travail, l'aspiration du liquide de nettoyage s'effectue dans des conditions optimum d'efficacité. Bien entendu, dans un tel cas, l'aspiration est réalisée uniquement à travers les canaux 5 qui débouchent sur la face de la raclette qui se trouve placée vers l'avant. Cependant, du fait même qu'il est prévu des orifices d'entrée 7 sur l'une et l'autre faces de la raclette 1, le présent dispositif de nettoyage peut être utilisé en étant incliné indifféremment dans un sens ou dans l'autre.The cleaning device thus formed is intended to be applied to the surface to be treated after cleaning thereof, by means of an appropriate cleaning liquid, this liquid being able to be spread in any desired manner. The purpose of the application of this device is to eliminate the liquid on the corresponding floor S so as to leave only a thin liquid film capable of disappearing quickly on drying. For this purpose, it is necessary to slide the squeegee 1 on the ground by placing the assembly in the inclined position shown in FIG. 4. The squeegee is then in contact with the ground by its lower edge 8 situated towards the front. Under these conditions, this edge repels before it the cleaning liquid spilled on the floor, so that it is immediately sucked through the orifices 7 located on the front face of the squeegee. Since the suction channels are provided inside the squeegee and their inlet ports 7 open in the immediate vicinity of the edge 8 in the working position, the suction of the cleaning liquid is carried out under optimum conditions of efficiency. Of course, in such a case, the suction is carried out only through the channels 5 which open onto the face of the squeegee which is placed forward. However, by the very fact that there are provided inlet ports 7 on both sides of the squeegee 1, the present cleaning device can be used by being inclined either in one direction or the other. .

La figure 6 représente une variante de réalisation de la raclette équipant le dispositif de nettoyage selon l'invention. Dans cette variante la raclette correspondante 1a comporte une découpe 16 en gradin le long de l'un des bords de son extrémité de travail. Quant aux canaux 5a d'aspiration, ils sont ménagés à l'intérieur de la partie du corps de cette raclette qui est située à l'aplomb de cette découpe en gradin. Les orifices d'entrée 7a de ces canaux se trouvent situés à l'endroit de cette découpe, à proximité immédiate de l'arête voisine 8a de l'extrémité de travail de la raclette.Figure 6 shows an alternative embodiment of the squeegee fitted to the cleaning device according to the invention. In this variant, the corresponding squeegee 1a comprises a cutout 16 in a step along one of the edges of its working end. As for the suction channels 5a, they are arranged inside the part of the body of this squeegee which is located directly above this step cutout. The inlet orifices 7a of these channels are located at the location of this cut, in the immediate vicinity of the neighboring edge 8a of the working end of the squeegee.

En conséquence, dans cette variante de réalisation, la raclette 1a doit être toujours orientée dans la position représentée à la figure 6 pour que les têtes de nettoyage soient déplacées dans le sens de la flêche F. On obtient ainsi les mêmes avantages que précédemment, c'est-à-dire une aspiration du liquide à éliminer, à proximité immédiate de l'arête 8a de raclage sur la surface lisse.Consequently, in this alternative embodiment, the squeegee 1a must always be oriented in the position shown in FIG. 6 so that the cleaning heads are moved in the direction of the arrow F. The same advantages are thus obtained as above, c that is to say, a suction of the liquid to be eliminated, in the immediate vicinity of the scraping edge 8a on the smooth surface.

Les figures 7 et 8 représentent une autre forme de réalisation du dispositif de nettoyage selon l'invention. Dans celle-ci le carter 2b de la tête de nettoyage correspondante porte non seulement une raclette élastique 1b, mais également une brosse 17 disposée en regard de l'une de ses grandes faces et qui est destinée à servir d'organe d'application d'un liquide de nettoyage sur la surface à nettoyer. L'alimentation de cette brosse en liquide de nettoyage est assurée par une série de petits canaux 18 débouchant en regard de celle-ci. Ces canaux partent d'une rampe de distribution 19 prévue sur ou dans le carter 2b, celle-ci étant raccordée par une canalisation 20 à un réservoir 21 contenant une réserve de liquide de nettoyage. Ce réservoir comporte un élément amovible de fermeture permettant de le remplir périodiquement.Figures 7 and 8 show another embodiment of the cleaning device according to the invention. In it the casing 2b of the corresponding cleaning head carries not only an elastic scraper 1b, but also a brush 17 arranged opposite one of its large faces and which is intended to serve of a member for applying a cleaning liquid to the surface to be cleaned. The supply of this brush with cleaning liquid is ensured by a series of small channels 18 opening opposite it. These channels start from a distribution ramp 19 provided on or in the casing 2b, the latter being connected by a pipe 20 to a reservoir 21 containing a reserve of cleaning liquid. This reservoir has a removable closure element allowing it to be filled periodically.

Cependant, le dispositif de nettoyage selon les figures 7 et 8 comporte par ailleurs les mêmes éléments que dans la forme de réalisation précédente, et ce en plus de la raclette 1b déjà mentionnée. Il comprend donc une pompe 11 à galets, à l'intérieur de laquelle aboutissent des conduites flexibles 10 d'aspiration, branchées sur les orifices de sortie des canaux 5 ménagés dans l'épaisseur de la raclette 1b. Les extrémités de ces conduites flexibles sont raccordées à un réservoir 15 destiné à recueillir le liquide sale de nettoyage après aspiration par la pompe 11. Bien entendu, le carter 2b comporte aussi un manchon 3 destiné à recevoir un manche de manoeuvre 4 ou une poignée de préhension.However, the cleaning device according to Figures 7 and 8 also includes the same elements as in the previous embodiment, in addition to the squeegee 1b already mentioned. It therefore comprises a pump 11 with rollers, inside which flexible suction pipes 10 terminate, connected to the outlet orifices of the channels 5 formed in the thickness of the squeegee 1b. The ends of these flexible pipes are connected to a reservoir 15 intended to collect the dirty cleaning liquid after aspiration by the pump 11. Of course, the casing 2b also includes a sleeve 3 intended to receive an operating handle 4 or a handle of gripping.

Le dispositif de nettoyage selon les figures 7 et 8 est destiné à être déplacé au contact de la surface à nettoyer, dans un sens et dans l'autre en l'inclinant alors différemment. En l'inclinant dans la position représentée à la figure 8 pour le déplacer selon le sens de la flèche F il est possible d'éliminer le liquide de nettoyage précédemment répandu sur le sol, et ce dans les mêmes conditions que dans la forme de réalisation selon les figures 1 à 4. Cependant, en inclinant ce même dispositif en sens inverse et en le faisant glisser dans le sens opposé à celui de la flèche F, il est possible d'utiliser la brosse 17 pour appliquer au préalable le liquide de nettoyage sur la surface à traiter. Ces deux opérations peuvent donc être effectuées successivement avec un outil unique de travail.The cleaning device according to FIGS. 7 and 8 is intended to be moved in contact with the surface to be cleaned, in one direction and in the other, while then tilting it differently. By tilting it in the position shown in Figure 8 to move it in the direction of arrow F it is possible to remove the cleaning liquid previously spilled on the floor, and this under the same conditions as in the embodiment according to Figures 1 to 4. However, by tilting the same device in the opposite direction and sliding it in the opposite direction to that of the arrow F, it is possible to use the brush 17 to apply the cleaning liquid on the surface to be treated. These two operations can therefore be carried out successively with a single working tool.

La figure 9 représente une variante de réalisation du dispositif de nettoyage selon les figures 7 et 8. Dans cette variante, la partie inférieure du carter 2c de ce dispositif est équipée d'une brosse rotative 17c disposée en regard de la face de la raclette 1c en bout de laquelle débouchent les canaux d'aspiration 5c ménagés dans l'épaisseur de cette raclette. Cette brosse rotative est destinée à remplacer la brosse fixe prévue dans la forme de réalisation selon les figures 7 et 8. Cependant, comme cette brosse 17c se trouve disposée en regard des orifices d'aspiration 7c, et non du côté opposé, le dispositif de nettoyage ainsi constitué est susceptible d'être déplacé sur la surface à nettoyer dans une seule direction F1, à la fois pour assurer l'épandage du liquide de nettoyage sur la surface à traiter et pour aspirer celui-ci derrière la brosse 17c grâce aux canaux 5c de la raclette correspondante.FIG. 9 represents an alternative embodiment of the cleaning device according to FIGS. 7 and 8. In this alternative, the lower part of the casing 2c of this device is equipped with a rotary brush 17c arranged opposite the face of the squeegee 1c at the end of which open the suction channels 5c formed in the thickness of this squeegee. This rotary brush is intended to replace the fixed brush provided in the embodiment according to Figures 7 and 8. However, as this brush 17c is located opposite the suction ports 7c, and not on the opposite side, the device cleaning thus formed is capable of being moved on the surface to be cleaned in one direction F1, both to ensure the spreading of the cleaning liquid on the surface to be treated and to suck it behind the brush 17c through the channels 5c of the corresponding squeegee.

Cependant, le dispositif de nettoyage selon l'invention peut faire l'objet de nombreuses autres formes de réalisation. Ainsi, les brosses 17 et 17c pourraient être remplacées par tous autres organes appropriés d'épandage d'un liquide de nettoyage sur une surface à traiter, par exemple un patin poreux ou spongieux. Comme déjà relevé dans le cas des deux formes de réalisation des figures 7 et 8 d'une part, et de la figure 9 d'autre part, cet organe d'application peut être situé en regard de la grande face de la raclette sur laquelle débouchent les canaux d'aspiration, ou bien sur sa grande face opposée. Mais il peut également être prévu une raclette du type de celle selon les figures 4 et 5, c'est-à-dire une raclette comportant des canaux d'aspiration débouchant sur l'une et l'autre de ses grandes faces.However, the cleaning device according to the invention can be the subject of numerous other embodiments. Thus, the brushes 17 and 17c could be replaced by any other suitable members for spreading a cleaning liquid on a surface to be treated, for example a porous or spongy pad. As already noted in the case of the two embodiments of FIGS. 7 and 8 on the one hand, and of FIG. 9 on the other hand, this applicator member can be located opposite the large face of the squeegee on which open the suction channels, or else on its large opposite face. However, there may also be provided a squeegee of the type of that according to FIGS. 4 and 5, that is to say a squeegee comprising suction channels opening onto one and the other of its large faces.

Par ailleurs, le carter du dispositif de nettoyage peut avoir une forme très différente de celle apparaissant sur les figures 1 à 7 et qui est plus spécialement conçue dans le cas d'un appareil destiné au nettoyage du sol. En effet, dans le cas d'un appareil prévu pour le nettoyage de vitres ou de toutes autres surfaces verticales, ce carter peut présenter une forme très différente afin de pouvoir être tenu aisément à la main au moyen d'une poignée de préhension.Furthermore, the housing of the cleaning device can have a shape very different from that appearing in FIGS. 1 to 7 and which is more especially designed in the case of an apparatus intended for cleaning the floor. In fact, in the case of a device intended for cleaning windows or any other vertical surface, this casing may have a very different shape in order to be able to be held easily in the hand by means of a grip handle.

En raison de ses avantages, le dispositif de nettoyage selon l'invention peut être utilisé avec une grande efficacité pour le nettoyage de diverses sortes de surfaces lisses. Ainsi qu'il a déjà été indiqué, l'invention a également pour objet les raclettes de nettoyage spécialement conçues pour équiper les dispositifs de nettoyage précédemment décrits.Because of its advantages, the cleaning device according to the invention can be used with great efficiency for cleaning various kinds of smooth surfaces. As already indicated, the invention also relates to cleaning scrapers specially designed to equip the cleaning devices described above.
