Description

APPAREIL DE NETTOYAGE DE SURFACE PLANE FLAT SURFACE CLEANER
La présente invention a pour objet, dans le domaine du nettoyage, un appareil de nettoyage utilisant un liquide, éventuellement destiné à être transformé en vapeur, et plus particulièrement le dispositif permettant d'apporter ce liquide. The present invention relates, in the field of cleaning, to a cleaning apparatus using a liquid, optionally intended to be converted into vapor, and more particularly the device making it possible to supply this liquid.
L'appareil de nettoyage utilisant un liquide selon l'invention trouvera une application particulièrement avantageuse dans le domaine des appareils de nettoyage de surface plane, notamment des sols.Ainsi, cet appareil, de nettoyage et son dispositif permettant de distribuer du liquide, consiste plus particulièrement en un balai de nettoyage utilisant un produit détergent, ou à vapeur, que celui-ci soit avec ou sans fil. The cleaning device using a liquid according to the invention will find a particularly advantageous application in the field of flat surface cleaning devices, in particular floors. Thus, this cleaning device and its device for dispensing liquid, consists of more particularly in a cleaning mop using a detergent or steam product, whether the latter is corded or cordless.
L'utilisation de produit détergent nécessite que ledit produit, pur ou dilué dans de l'eau, soit utilisé en quantité juste nécessaire. The use of a detergent product requires that said product, pure or diluted in water, be used in just the amount necessary.
En ce qui concerne la vapeur, sa production nécessite de mettre en contact de l'eau et de la chaleur, et plus particulièrement de l'eau avec une surface chaude. De préférence, la quantité d'eau doit être choisie, en fonction notamment de la chaleur et des dimensions de la surface chaude, à savoir que si elle est trop faible il y a peu de vapeur, et si elle est trop importante d'une part toute l'eau n'est pas transformée en vapeur, une partie demeurant sous forme d'eau chaude non utilisable, et d'autre part il y a un risque de refroidissement de la surface chaude qui est alors moins efficace. With regard to steam, its production requires contacting water and heat, and more particularly water with a hot surface. Preferably, the amount of water should be chosen, depending in particular on the heat and the dimensions of the hot surface, namely that if it is too low there is little steam, and if it is too large of a on the other hand, not all the water is transformed into steam, some remaining in the form of hot water that cannot be used, and on the other hand there is a risk of cooling the hot surface which is then less effective.
De plus la quantité d'eau délivrée doit l'être en fonction des besoins, en sorte qu'il est peu efficient que la distribution soit réalisée automatiquement en rythme. In addition, the quantity of water delivered must be as a function of needs, so that it is inefficient for the distribution to be carried out automatically in rhythm.
On connaît des dispositifs de balai vapeur, comprenant un générateur de vapeur dont l'alimentation en eau est réalisée à la demande par un système de pompe manuelle ou électrique. Le document WO 01/22861 décrit un balai vapeur comprenant un système de distribution de liquide au travers d'une pompe actionnée par un moteur électrique, lui-même commandé par un bouton interrupteur disposé au niveau de la poignée du balai. C'est donc l'utilisateur qui commande la production de vapeur, sans toutefois que cette distribution soit faite de manière rationnelle. La présente invention a pour but de remédier aux inconvénients précités en proposant un appareil de nettoyage de surface plane, de type balai, utilisant un liquide, éventuellement destiné à être transformé en vapeur, et qui comporte un dispositif d'apport de ce liquide qui permet de dispenser la juste quantité de liquide nécessaire lors de son utilisation. Steam mop devices are known, comprising a steam generator, the water supply of which is provided on demand by a manual or electric pump system. Document WO 01/22861 describes a steam mop comprising a liquid distribution system through a pump actuated by an electric motor, itself controlled by a switch button arranged at the level of the mop handle. It is therefore the user who controls the production of steam, without however this distribution being made in a rational manner. The object of the present invention is to remedy the aforementioned drawbacks by proposing a cleaning apparatus for a flat surface, of the broom type, using a liquid, possibly intended to be transformed into vapor, and which comprises a device for supplying this liquid which allows to dispense the right amount of liquid necessary during its use.
Selon l'invention, l'appareil de nettoyage de surface plane, de type balai, utilisant un liquide, éventuellement de l'eau destinée à être transformée en vapeur, et qui comporte un dispositif d'apport de ce liquide, se caractérise en ce qu'il comporte au moins une roue, apte à rouler sur ladite surface à nettoyer lors de son déplacement sur celle-ci, ladite roue étant associée à des moyens de pompage, actionnés par le mouvement en rotation de ladite roue, lesdits moyens de pompage alimentant ledit dispositif d'apport de liquide proportionnellement au roulage de ladite roue et donc du déplacement de l'appareil. According to the invention, the device for cleaning a flat surface, of the broom type, using a liquid, optionally water intended to be transformed into steam, and which comprises a device for supplying this liquid, is characterized in that that it comprises at least one wheel, able to roll on said surface to be cleaned during its movement on the latter, said wheel being associated with pumping means, actuated by the rotational movement of said wheel, said pumping means supplying said liquid supply device in proportion to the rolling of said wheel and therefore to the movement of the device.
Indépendamment du rapport de réduction choisi entre la roue et les moyens de pompage, l'apport liquide est proportionnel à la distance parcourue par l'appareil de nettoyage sur la surface planeRegardless of the reduction ratio chosen between the impeller and the pumping means, the liquid supply is proportional to the distance traveled by the cleaning device on the flat surface
Le liquide pompé, de l'eau, un produit détergent pur ou dilué, est projeté de plusieurs manières, essentiellement et préférentiellement soit en brumisation, soit en goutte par goutte. The pumped liquid, water, a pure or diluted detergent product, is sprayed in several ways, essentially and preferably either by misting or drop by drop.
Selon une caractéristique additionnelle de l'appareil de nettoyage selon l'invention, les moyens de projection consistent en des moyens de pulvérisation. According to an additional characteristic of the cleaning apparatus according to the invention, the projection means consist of spray means.
Selon une autre caractéristique additionnelle de l'appareil de nettoyage selon l'invention, les moyens de projection consistent en un dispositif de goutte à goutte. According to another additional characteristic of the cleaning apparatus according to the invention, the projection means consist of a drip device.
Selon une autre caractéristique additionnelle de l'appareil de nettoyage selon l'invention, les moyens de pompage consistent en une pompe péristaltique liée directement à la roue. According to another additional characteristic of the cleaning apparatus according to the invention, the pumping means consist of a peristaltic pump linked directly to the impeller.
On notera que bien entendu les moyens de pompage ne sont pas limités à une pompe péristaltique, il existe d'autres moyens de pompage activables par un mouvement de rotation. Selon une autre caractéristique additionnelle de l'appareil de nettoyage selon l'invention, il comporte un système de débrayage intercalé entre la roue et les moyens de pompage, conçu apte à n'autoriser l'activation de ces derniers que dans un seul sens de rotation de ladite roue. It will be noted that of course the pumping means are not limited to a peristaltic pump, there are other pumping means which can be activated by a rotational movement. According to another additional characteristic of the cleaning device according to the invention, it comprises a disengagement system interposed between the wheel and the pumping means, designed to allow the activation of the latter only in one direction of the pump. rotation of said wheel.
Selon une autre caractéristique additionnelle de l'appareil de nettoyage l'appareil de nettoyage selon l'invention, une roue libre est intercalée entre la roue et les moyens de pompage. According to another additional characteristic of the cleaning apparatus the cleaning apparatus according to the invention, a free wheel is interposed between the wheel and the pumping means.
Selon une autre caractéristique additionnelle de l'appareil de nettoyage selon l'invention, un système à cliquet est intercalé entre la roue et les moyens de pompage. According to another additional characteristic of the cleaning apparatus according to the invention, a ratchet system is interposed between the wheel and the pumping means.
L'utilisation d'une roue libre ou d'un système à cliquet permet de limiter le fonctionnement de la pompe à un seul sens de déplacement de la roue. Ainsi, non seulement le débit de liquide est lié à la distance parcourue par la roue et donc l'appareil de nettoyage, mais lors de l'utilisation de ce dernier dans des mouvements normaux d'allers et retours, il n'y a pas d'apport de liquide, et donc pas de création de vapeur pour un balai vapeur, dans l'un des deux mouvements, préférentiellement le retour. The use of a freewheel or a ratchet system makes it possible to limit the operation of the pump to a single direction of movement of the impeller. Thus, not only is the liquid flow rate linked to the distance traveled by the wheel and therefore the cleaning device, but when using the latter in normal back and forth movements, there is no supply of liquid, and therefore no creation of steam for a steam mop, in one of the two movements, preferably the return.
Selon une autre caractéristique additionnelle de l'appareil de nettoyage selon l'invention, les moyens de pompage sont intégrés dans la roue. According to another additional characteristic of the cleaning apparatus according to the invention, the pumping means are integrated in the wheel.
Les avantages et les caractéristiques de l'appareil de nettoyage selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the cleaning apparatus according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé : In the attached drawing:
La figure 1 représente une vue schématique en coupe d'un premier mode réalisation d'une partie d'un appareil de nettoyage de surface plane selon l'invention, Figure 1 shows a schematic sectional view of a first embodiment of part of a flat surface cleaning apparatus according to the invention,
La figure 2 représente une vue schématique en coupe d'un deuxième mode réalisation de la même partie du dispositif,Figure 2 shows a schematic sectional view of a second embodiment of the same part of the device,
La figure 3 représente une vue schématique en coupe d'un troisième mode réalisation de la même partie du dispositif, En référence à ces figures 1, 2 et 3, on peut voir un appareil M de nettoyage de surface plane, et plus particulièrement une partie de celui-ci à savoir une pompe 1 et une roue 2, la pompe 1 étant destinée à dispenser un liquide, de préférence de l'eau à un générateur de vapeur. Figure 3 shows a schematic sectional view of a third embodiment of the same part of the device, Referring to these Figures 1, 2 and 3, one can see a flat surface cleaning apparatus M, and more particularly a part thereof, namely a pump 1 and a wheel 2, the pump 1 being intended to dispense a liquid, preferably water to a steam generator.
La roue 2 est liée à un appareil de nettoyage M, un balai vapeur par exemple, et est destinée à rouler sur la surface à nettoyer. Cette roue 2 peut faire partie d'un ensemble comprenant une ou plusieurs autres roues, en sorte de supporter la partie active l'appareil de nettoyage, ou bien constituer uniquement une jauge, à savoir le moyen de détermination de la quantité nécessaire de liquide à dispenser. The wheel 2 is linked to a cleaning device M, a steam mop for example, and is intended to roll over the surface to be cleaned. This wheel 2 can be part of an assembly comprising one or more other wheels, so as to support the active part of the cleaning apparatus, or else constitute only a gauge, namely the means for determining the necessary quantity of liquid to be to dispense.
La pompe 1 est de type péristaltique et comporte, de manière connue en soi, un conduit souple 10 pour le cheminement de liquide, un siège support 11 de forme annulaire comprenant sur sa paroi intérieure une gorge 12 dans laquelle est disposé le conduit souple 10, et intérieurement des galets 13 portés chacun par une chape 14, solidaire d'un arbre 15 dont la rotation entraîne les galets à rouler sur le conduit souple 10 en sorte de l'écraser et ainsi y repousser le liquide qu'il contient. The pump 1 is of the peristaltic type and comprises, in a manner known per se, a flexible duct 10 for the flow of liquid, a support seat 11 of annular shape comprising on its inner wall a groove 12 in which the flexible duct 10 is arranged, and internally rollers 13 each carried by a yoke 14, integral with a shaft 15 whose rotation causes the rollers to roll on the flexible duct 10 so as to crush it and thus push back the liquid it contains.
La roue 2 et la pompe 1 sont liées en rotation, en sorte que c'est la longueur de déplacement qui commande, au travers de la pompe, la quantité de liquide à apporter au générateur de vapeur d'un balai vapeur par exemple. The impeller 2 and the pump 1 are linked in rotation, so that it is the displacement length which controls, through the pump, the quantity of liquid to be supplied to the steam generator of a steam mop, for example.
De manière avantageuse, la pompe 1 ne fonctionne que dans un seul sens de déplacement de l'appareil de nettoyage, ce qui est obtenu par une liaison débrayable intercalée entre la pompe 1 et la roue 2. Advantageously, the pump 1 operates only in one direction of movement of the cleaning device, which is obtained by a disengageable connection interposed between the pump 1 and the impeller 2.
Les figures 1, 2 et 3 montrent des variantes de cette liaison débrayable, sachant que d'autres modes de réalisation sont possibles. Figures 1, 2 and 3 show variants of this disengageable connection, knowing that other embodiments are possible.
Sur la figure 1 l'arbre 15 est lié à la roue 2 au travers d'une roue libre 3, qui peut être à galets ou à cliquet. In FIG. 1, the shaft 15 is linked to the wheel 2 through a free wheel 3, which may be with rollers or with a ratchet.
Sur la figure 2, la roue 2 tourne librement sur l'arbre 15 par l'intermédiaire d'un roulement 20, et la roue 2 comporte intérieurement une couronne 21 à rochets avec laquelle coopère une roue 16 montée à rotation sur l'arbre 15, et munie en périphérie d'un ou de plusieurs cliquets.On notera qu'inversement les rochets peuvent être disposés sur la roue 16 et le ou les cliquets dans la roue 21. In FIG. 2, the wheel 2 rotates freely on the shaft 15 by means of a bearing 20, and the wheel 2 internally comprises a ratchet ring 21 with which a wheel 16 cooperates rotatably mounted on the shaft 15 , and provided at the periphery of a or more pawls. It will be noted that conversely the ratchets can be arranged on the wheel 16 and the pawl (s) in the wheel 21.
Sur la figure 3 l'embrayage est réalisé par friction, au travers d'un disque 17 mobile sur l'arbre 15 et repoussé vers la roue 2 sous l'action d'un ressort 18, tandis que la roue 2 comporte, en regard du disque 17, une paroi 22 avec laquelle le disque 17 est maintenue en contact sous l'action du ressort 18, les surfaces en contact étant traitées pour autoriser une solidarisation du disque 17 avec la roue 2 dans un seul sens de rotation et donc l'entraînement de la pompe 1. Les surfaces de contact peuvent être traitées de différentes manières, ce peut être par exemple, non limitativement, des dents radiales de profil de type rochet, tandis que le ressort 18 est de faible pouvoir de répulsion. In FIG. 3 the clutch is produced by friction, through a disc 17 movable on the shaft 15 and pushed back towards the wheel 2 under the action of a spring 18, while the wheel 2 comprises, opposite of the disc 17, a wall 22 with which the disc 17 is kept in contact under the action of the spring 18, the contacting surfaces being treated to allow the disc 17 to be secured to the wheel 2 in a single direction of rotation and therefore the drive of the pump 1. The contact surfaces can be treated in different ways, for example, without limitation, radial teeth of ratchet type profile, while the spring 18 is of low repulsion power.
On notera que, quel que soit le mode de réalisation, il est possible d'intégrer la pompe 1 à l'intérieur de la roue 2. It will be noted that, whatever the embodiment, it is possible to integrate the pump 1 inside the impeller 2.
