Le document EP 0.422.977 A1 du même inventeur décrit un dispositif d'aspiration avec raclette pour l'élimination de l'eau sale lors du nettoyage de certaines surfaces. La raclette comporte selon une variante particulière de réalisation une découpe en gradin le long de l'un des bords de son extrémité de travail et comporte au moins un canal d'aspiration ménagé à l'intérieur de la partie du corps de cette raclette qui est située à l'aplomb de cette découpe en gradin.Document EP 0.422.977 A1 by the same inventor describes a suction device with a squeegee for removing dirty water when cleaning certain surfaces. The squeegee comprises, according to a particular variant of embodiment, a stepped cut along one of the edges of its working end and comprises at least one suction channel formed inside the part of the body of this squeegee which is located directly above this tiered cutout.

En référence aux figures 1 à 4, un dispositif selon l'invention désigné dans son ensemble par la référence 1 est destiné en particulier au nettoyages de grandes surfaces lisses, telles que des sols ou des carrelages.Referring to Figures 1 to 4, a device according to the invention designated as a whole by the reference 1 is intended in particular for cleaning large smooth surfaces, such as floors or tiles.
Le dispositif 1 comporte un organe de nettoyage 2, une partie centrale 3 et une poignée 4 emboîtables séquentiellement de manière étanche l'une avec l'autre au moyen de conformations et de joints d'étanchéité appropriés.The device 1 comprises a
L'organe de nettoyage 2 comporte une raclette 5 monobloc en élastomère, caoutchouc ou matériau analogue. La raclette 5 présente une conformation en gradin 6 et au moins un canal central 7 communiquant à travers un embout 8 avec une pipe d'aspiration 9 du liquide usagé répandu sur le sol.The
L'organe de nettoyage 2 présente une préférence un logement 10 de réception de la raclette 5 de manière à en faciliter le remplacement.The
On prévoit avantageusement de monter selon une inclinaison sensiblement symétrique par rapport au plan médian longitudinal L de l'organe de nettoyage 2, un organe d'épandage 11 amovible, du type brosse, patin poreux, patin spongieux ou analogue. L'organe d'épandage 11 est utilisé pour épandre régulièrement du liquide propre débouchant par au moins une canalisation centrale 12 d'amenée de liquide propre débouchant sensiblement dans le plan médian longitudinal L par un orifice 12a.Advantageously, provision is made to mount at a substantially symmetrical inclination relative to the longitudinal median plane L of the
L'organe de nettoyage 2 présente sensiblement une forme de T, dont la branche 14 correspond à un conduit d'emboîtement étanche avec la partie inférieure de la partie centrale 3.The
L'étanchéité est assurée par des joints toriques 15a, 15b disposés dans des gorges 16a, 16b et le verrouillage est assuré par un bouton d'encliquetage 17 rétractable sur simple poussée d'un doigt.The seal is ensured by O-rings 15a, 15b arranged in
L'organe de nettoyage 2 est creux et comporte un bouchon 18 de vidange de liquide usagé, de sorte qu'après assemblage étanche de l'organe de nettoyage 2 à la partie centrale 3, l'intérieur 19 de l'organe de nettoyage forme avec l'intérieur 20 du bas de la partie centrale 3 un réservoir d'aspiration de liquide usagé.The
Le réservoir 19-20 ainsi formé reçoit le liquide usagé par la pipe 9 y débouchant, l'aspiration résultant d'une dépression créée par la tubulure de mise en dépression 21 solidaire de la partie centrale 3 du dispositif.The reservoir 19-20 thus formed receives the liquid used by the
La partie centrale 3 comporte deux bouchons annulaires d'étanchéité 22 et 23 compris entre la paroi extérieure 24 tubulaire, de section rectangulaire à bords arrondis, elliptique ou analogue et la tubulure de dépression 21 précitée.The
Les bouchons 22, 23 délimitent entre eux un réservoir 25 de liquide nettoyant apte à être alimenté grâce au bouchon de remplissage 26. Le réservoir 25 intégré dans la partie centrale 3 en forme de manche est séparé du réservoir 20 par le bouchon 22 fixé à demeure par exemple par collage, thermosoudage ou un procédé analogue et communique avec le conduit d'amenée 12 de liquide nettoyant par l'intermédiaire d'une canalisation 26a de traversée du bouchon 22 et de communication avec la canalisation 12 d'amenée de liquide de nettoyage propre.The
On prévoit à cet effet que les conformations correspondantes de la canalisation 26a et de la canalisation 12 assurent un encliquetage étanche de ces canalisations l'une avec l'autre, lors de l'assemblage de la partie centrale 3 avec l'organe de nettoyage 2.It is provided for this purpose that the corresponding conformations of the
Un bouchon 27 monté sur un système élastique 28 commandable par une tringle 29 ou moyen mécanique analogue de commande à distance obture l'extrémité supérieure de la canalisation 26a.A
La commande 29 agit par appui sur l'extrémité d'une conformation élastique 28 en cantilever qui, en position de repos, obture l'admission de la canalisation 26a et, en position d'appui vers le bas de la tringle 29, soulève le bouchon 27 et alimente la canalisation 26a.The
La tringle 29 montée à coulissement dans la partie centrale 3 et traversant le bouchon supérieur 23 comporte une extrémité supérieure 29a s'emboîtant et coopérant avec une organe de manoeuvre 30 prisonnier à coulissement dans la tête 4 du dispositif selon l'invention.The
La tête 4 présente une forme élargie constituant un boîtier 31 dans lequel est monté une partie évasée 32 formant corps pour une turbine d'aspiration 33 apte à créer une dépression à travers la tubulure 21 dans le réservoir 20 d'aspiration de liquide usagé et à refouler l'air aspiré vers l'extérieur à travers des orifices 34 appropriés.The head 4 has an enlarged shape constituting a
La turbine 33 est entraînée en rotation par un petit moteur électrique 35 disposé coaxialement au-dessus de la turbine 33 ; le moteur électrique 35 est alimenté par un jeu de batteries 36 en série avec un interrupteur d'alimentation 37 et rechargeables au moyen d'un connecteur coaxial 38.The
L'actionnement de l'organe de manoeuvre 30 est effectué au moyen d'un bouton coulissant 39, tandis que la fixation mécanique de la tête 4 sur la partie centrale 3 résulte de l'encliquetage d'un bouton poussoir 40 avec un orifice correspondant de la paroi 24 de la partie centrale.The actuating
Cette disposition fonctionnelle permet ainsi la séparation du dispositif selon l'invention en trois modules remplaçables séparément :
- . le
premier module 2 ou organe de nettoyage comprend toutes les pièces d'usure telles que raclette 5,organe d'épandage 11, au contact des surfaces à nettoyer, - . le deuxième
module 3 ou partie centrale fait office de réservoir de liquide propre et de réceptacle de liquide sale et présente un encombrement correspondant à celui des manches des appareils de l'art antérieur, - . le troisième module 4 ou tête fait office de poignée et regroupe tous les moyens de commande et d'énergie : source de dépression, commande d'alimentation en liquide nettoyant, moteur électrique et batteries.
- . the
first module 2 or cleaning member comprises all the wearing parts such as squeegee 5, spreadingmember 11, in contact with the surfaces to be cleaned, - . the
second module 3 or central part acts as a reservoir for clean liquid and receptacle for dirty liquid and has a space corresponding to that of the handles of the devices of the prior art, - . the third module 4 or head acts as a handle and groups together all of the control and energy means: vacuum source, control of supply of cleaning liquid, electric motor and batteries.
On voit dans ce premier mode de réalisation que, à l'état monté, le dispositif comporte une enceinte essentiellement tubulaire comportant deux compartiments superposés étanches l'un à l'autre, à savoir le réservoir de liquide usagé 19-20 en contact immédiat avec la tête de nettoyage 5, et le réservoir de liquide nettoyant 25 traversé par la tubulure d'aspiration d'air 21, cette dernière étant reliée en partie haute aux moyens de dépression 32-36 portés par la poignée de préhension 4. On voit également que dans le réservoir de liquide usagé 19-20, les extrémités en regard de la pipe d'aspiration de liquide usagé 9 et de la tubulure d'aspiration d'air 21 sont disposées selon sensiblement le même axe vertical et sont espacées axialement. Ceci assure que le liquide aspiré par la pipe 9 ne risque pas de pénétrer dans la tubulure 21. En outre, la hauteur de la pipe 9 à l'intérieur du réservoir 19-20 est suffisante pour donner au dispositif une capacité de ramassage correspondant à la surface d'une pièce à nettoyer.It can be seen in this first embodiment that, in the assembled state, the device comprises an essentially tubular enclosure comprising two superimposed compartments which are sealed to one another, namely the used liquid tank 19-20 in immediate contact with the cleaning head 5, and the cleaning
Si le liquide usagé dépasse le niveau supérieur de la pipe 9, celle-ci fera fonction de trop-plein avertissant l'utilisateur qu'il doit vider le réservoir 19-20.If the used liquid exceeds the upper level of the
Les figures 5 à 10 représentent un second mode de réalisation de l'invention. Les parties, présentant les mêmes fonctions que dans l'exemple de réalisation précédent, portent les mêmes références.Figures 5 to 10 show a second embodiment of the invention. The parts, having the same functions as in the previous embodiment, have the same references.
Selon ce deuxième exemple de réalisation, l'enceinte tubulaire du dispositif 1 est divisée en trois compartiments étagés dans le sens vertical : le compartiment inférieur constituant le réservoir de liquide usagé 19-20, le compartiment intermédiaire 41 constituant le logement des moyens de dépression et le compartiment supérieur constituant le réservoir de liquide nettoyant 25.According to this second embodiment, the tubular enclosure of the device 1 is divided into three compartments stepped in the vertical direction: the lower compartment constituting the used liquid reservoir 19-20, the
Dans l'exemple représenté, cet ensemble est formé d'une seule pièce par soufflage de manière plastique, le compartiment intermédiaire étant obtenu par enfoncement et rapprochement des deux parois de l'enceinte comme on le voit en particulier sur la figure 6.In the example shown, this assembly is formed in one piece by plastic blowing, the intermediate compartment being obtained by pressing in and bringing the two walls of the enclosure together as seen in particular in FIG. 6.
Cependant, ces trois compartiments pourraient en variante être formés d'éléments séparés emboîtables de manière étanche de manière analogue à l'exemple de réalisation précédent.However, these three compartments could alternatively be formed from separate elements which can be fitted in a sealed manner in a manner similar to the previous embodiment.
Comme dans l'exemple de réalisation précédent le réservoir de liquide usagé comporte à sa base une extension transversale 19 munie d'un bouchon de vidange 18, ceci afin de donner au dispositif l'allure générale d'un balai ménager classique.As in the previous embodiment, the used liquid reservoir has at its base a
Cependant cette conformation n'est pas essentielle et l'extension transversale pourrait parfaitement être supprimée, le dispositif étant alors de section uniforme depuis pratiquement l'embase de sa poignée jusqu'à l'extrémité du réservoir de liquide usagé.However, this conformation is not essential and the transverse extension could perfectly be eliminated, the device then being of uniform section from practically the base of its handle to the end of the used liquid reservoir.
Le fond de l'extension 19 comporte une ouverture médiane pour le passage de la pipe d'aspiration 9 et, venus de matière, deux tétons 42 pour l'encliquetage d'une tête de nettoyage 43 qui porte la raclette 5 et les moyens d'épandage du liquide nettoyant représentés ici sous forme de poils de brosse 11 (figure 7).The bottom of the
Sur les côtés latéraux du dispositif, sont disposées, venues de matière, deux conduites externes 44, 45 diamétralement opposées par rapport à l'axe vertical médian du dispositif. La conduite 44 est destinée à amener le liquide nettoyant par gravité depuis le réservoir 25 jusqu'à l'orifice 45 d'alimentation à l'extrémité inférieure du réservoir 19. A cet effet, sensiblement au niveau du bas du réservoir 25, on a ménagé une mise en communication directe (non représentée) entre le réservoir 25 et la conduite 44. A l'intérieur de la conduite 44 on fait, en outre, passer un câble souple 47 qui s'étend sur toute la hauteur du dispositif et dont l'extrémité inférieure est munie d'une bouchon conique 48 (figure 9) coopérant avec l'orifice 46. L'extrémité supérieure du câble souple 49 débouche au-dessus du réservoir 25 dans l'enceinte ménagée entre la paroi externe du dispositif et le goulot de remplissage 50 du réservoir 25 où il est monté par des moyens de ressort le rappelant pour maintenir le bouchon 48 en position d'obturation de l'orifice 46. En service, le mouvement d'ouverture de l'orifice 46 sera commandé par le coulissement du bouton 30 (figure 5) qui forme le capot de fermeture coulissant d'une face du dispositif au niveau de la poignée 4. Pour permettre le passage de l'extrémité 49 du câble 44 à l'intérieur de son enceinte, une ouverture (non représentée) est pratiquée dans la conduite 44 au niveau de cette enceinte.On the lateral sides of the device, two
La conduite 45 diamétralement opposée à la conduite 44 est également équipée d'un câble souple 51 qui aboutit dans le compartiment intermédiaire 41 pour actionner l'interrupteur électrique du moteur 35. De manière analogue au câble 46, le câble 51 est monté à son extrémité supérieure par des moyens de ressort de rappel et manoeuvré par un bouton 30 symétrique du précédent.The
On comprend que la conduite 45 pourrait être interrompue au-dessous de l'interrupteur 37. Dans l'exemple représenté, elle est cependant prolongée jusqu'à l'extrémité inférieure du dispositif pour des raisons d'équilibre esthétique.It is understood that the
Le compartiment intermédiaire 41 logeant le moteur 35, la turbine 33 et les batteries 36 est fermé par un capot amovible 52 muni d'ouïes d'évacuation 34 de l'air aspiré par la turbine 33. Le compartiment 41 comporte également des ouïes 34 symétriques à celles du capot 52.The
Alors que dans l'exemple de réalisation précédent, à l'intérieur du réservoir de liquide usagé 19-20, la tubulure 21 et la pipe 9 étaient disposées avec un léger décalage entre leurs axes de symétrie verticale, dans le présent exemple de réalisation elles sont alignées sur le même axe. Comme dans l'exemple précédent, les extrémités en regard de la pipe 9 et de la tubulure sont séparées axialement par un espace permettant au liquide usagé de retomber dans le réservoir 19-20, le long de la pipe 9 sans risque de pénétrer dans la tubulure 21.While in the previous embodiment, inside the used liquid tank 19-20, the
Selon une variante de réalisation représentée sur ce deuxième exemple de réalisation, mais qui est applicable aussi à l'exemple précédent, l'extrémité de la tubulure 21 en regard de la pipe 9 est coiffée d'une cloison transversale 53 reliée à la tubulure par des pattes 54.According to an alternative embodiment shown in this second embodiment, but which is also applicable to the previous example, the end of the
La cloison 53 est de section plus grande que celle de la tubulure de manière à constituer un chapeau déflecteur qui empêche le liquide de pénétrer dans la tubulure dans le cas où l'utilisateur relève le dispositif par exemple lorsqu'il veut changer la raclette 5 ou la brosse 11.The
En variante, cette disposition pourrait être réalisée par une cloison obturant l'extrémité de la tubulure 21, des ouvertures radiales étant pratiquées dans ladite tubulure à proximité immédiate de la cloison.As a variant, this arrangement could be made by a partition closing off the end of the
Selon une variante de réalisation particulièrement avantageuse, la tubulure 21 loge un goupillon 54 dont les poils apparaissent dans les ouvertures d'extrémité de la tubulure, le manche de ce goupillon étant orienté vers la turbine 33.According to a particularly advantageous embodiment, the
Ce goupillon 54 a deux fonctions. D'une part, lorsqu'il est logé dans la tubulure 21, il empêche les grosses impuretés qui pourraient être aspirées par la dépression (par exemple des mégots de cigarettes ou analogues) de pouvoir pénétrer dans la tubulure 21.This
D'autre part, lorsque le goupillon est retiré de la tubulure, il sert à nettoyer la pipe 9 qui doit être parfaitement propre et lisse afin que d'éventuels dépôts ne constituent pas des obstacles à l'aspiration de l'eau usée.On the other hand, when the bottle brush is removed from the tubing, it is used to clean the
Pour permettre l'accès au goupillon 54, on a prévu ans cet exemple de réalisation de monter l'ensemble moteur 35-turbine 33 de manière amovible dans son compartiment intermédiaire 41. Si l'on veut appliquer cette variante à l'exemple de réalisation précédent, il suffit de prévoir que la cloison 53 soit montée amovible à l'extrémité de la tubulure 21.To allow access to the
La Figure 8 illustre les moyens de recharge des batteries du dispositif dans l'exemple de réalisation de la figure 5. A cet effet, on prévoit dans la paroi du capot 52 un évidement 55 muni d'un connecteur coaxial 38. Cet évidement permet à l'ensemble du dispositif de venir s'adapter sur une monture 56 fixée au mur M par un piton 57 et raccordée au réseau électrique par le cordon d'alimentation 58. La prise (non représentée) sera alors équipée d'un transformateur usuel.FIG. 8 illustrates the means for recharging the batteries of the device in the embodiment of FIG. 5. For this purpose, there is provided in the wall of the cover 52 a
