Abstract

The wheel-mounted appliance is propelled by hand and uses high pressure water jets (6) to clean playing surfaces (9) etc. e.g. porous concrete tennis courts. It uses an angularly (8) adjustable nozzle box (4) mounted in a bottomless housing (3), with a handled (11) rigid water feed (10) connecting to the box (4). An axle in the housing side wall bores locates two rear wheels (2). The front of the housing locates a suction head (12) connected to a vacuum line (15). The suction intake (14) may be at the level of the playing surface and may lead the jet impact line by 3 to 35 mm. Waste water generated by the cleansing process is evacuated by the vacuum line (12-15).

Description

Dispositif de nettoyage de surfaces compactes telles que des sols.Device for cleaning compact surfaces such as floors.

La présente invention concerne un dispositif de nettoya ge de surfaces compactes et, plus particulièrement des sols. The present invention relates to a device for cleaning compact surfaces and more particularly floors.

Depuis de longues années, l'eau sous pression additionnée ou non de détergents est utilisée comme agent de nettoyage de surfaces dures. Pour le dégraissage des pièces mécaniques, l'eau est utilisée sous forme de vapeur. Comme le réseau four nit de l'eau de ville sous une pression variant entre 3 et 7 bars, on recourt à une pompe pour élever la pression du jet d'eau afin de la porter à une valeur supérieure. For many years, pressurized water with or without detergents has been used as a cleaning agent for hard surfaces. For degreasing mechanical parts, water is used in the form of steam. As the network supplies town water under a pressure varying between 3 and 7 bars, a pump is used to raise the pressure of the water jet in order to bring it to a higher value.

Toutefois, l'utilisation de l'eau sous pression est limitée car elle présente de nombreux inconvénients. En effet, plus le sol ou la surface à nettoyer est encrassé, plus il faut augmenter la pression et déterminer préalablement l'angle d'impact le plus approprié du ou des jets d'eau sur ladite surface à nettoyer. Plais alors, se posent les problèmes de l'évacuation de l'eau chargée de déchets et de la protection de lgenvironne ment immédiat de la surface à nettoyer. Lorsque l'eau est addi tionnée de détergent, le problème de l'évacuation est plus critique car cette eau mélangée à un détergent constitue une pollu- tion non négligeable.Quant à l'environnement immédiat de la surface à nettoyer, il est impératif de le protéger des éclaboussures, ce qui peut exiger des moyens de protection importants et onéreux. However, the use of pressurized water is limited because it has many drawbacks. Indeed, the more the soil or the surface to be cleaned is clogged, the more it is necessary to increase the pressure and determine beforehand the most appropriate impact angle of the water jet (s) on said surface to be cleaned. Please then, there are the problems of removing waste-laden water and protecting the immediate environment from the surface to be cleaned. When water is added with detergent, the problem of evacuation is more critical because this water mixed with detergent constitutes significant pollution. As for the immediate environment of the surface to be cleaned, it is imperative to protect it from splashes, which may require significant and costly means of protection.

La présente invention a pour but de pallier ces inconvénients et de proposer un dispositif simple dans sa structure et qui présente des moyens aptes à protéger l'environnement même très proche de la surface à nettoyer. The object of the present invention is to overcome these drawbacks and to propose a device which is simple in structure and which has means capable of protecting the environment even very close to the surface to be cleaned.

La présente invention a alors pour objet un dispositif de nettoyage, du type comportant un châssis mobile sur lequel sont montés de façon articulée des moyens de projection de fluide pour pression aptes à permettre le réglage de l'angle et de la force d'impact du fluide sur ladite surface à nettoyer, ledit dispositif étant caractérisé en ce qu'il comprend en outre des moyens de récupération du fluide de nettoyage chargé des déchets enlevés à la surface nettoyée. The present invention therefore relates to a cleaning device, of the type comprising a movable frame on which are hingedly mounted means for projecting fluid for pressure capable of allowing the angle and the impact force of the fluid on said surface to be cleaned, said device being characterized in that it further comprises means for recovering the cleaning fluid charged with the waste removed from the cleaned surface.

Un avantage de la présente invention réside dans le fait que les éclaboussures sont enfermées dans un carter de protection fermé et ne peuvent donc se disperser ou atteindre l'environnement extérieur audit carter. An advantage of the present invention lies in the fact that the splashes are enclosed in a closed protective casing and therefore cannot disperse or reach the environment external to said casing.

Selon une autre caractéristique, les moyens de récupération comprennent au moins un organe d'aspiration dont la tête d'aspiration débouche à l'intérieur du châssis fermé, ce qui permet d'aspirer l'eau de nettoyage et les déchets désincrustés de la surface à nettoyer. En outre, cette aspiration de l'eau usée constitue un essorage de la surface nettoyée qui peut donc être réutilisée immédiatement après lavage, ce qui n'est pas le cas avec les dispositifs de nettoyage de l'art antérieur où il faut attendre que la surface nettoyée soit sèche ou tout au moins débarrassée de l'eau de nettoyage. According to another characteristic, the recovery means comprise at least one suction member, the suction head of which opens out inside the closed frame, which makes it possible to suck the cleaning water and the encrusted waste from the surface. to clean. In addition, this suction of the wastewater constitutes a spinning of the cleaned surface which can therefore be reused immediately after washing, which is not the case with the cleaning devices of the prior art where it is necessary to wait for the surface cleaned either dry or at least free of cleaning water.

Enfin, il faut noter que l'eau usée peut facilement être stockée dans une citerne de récupération pour ensuite être régénérée le cas échéant, ce qui procure une économie substantielle de l'eau, ce qui n'est pas négligeable même si l'opinion générale considère l'eau comme un produit bon marché. Finally, it should be noted that the used water can easily be stored in a recovery tank and then be regenerated if necessary, which provides a substantial saving in water, which is not negligible even if opinion general regards water as a cheap product

D'autres avantages et caractéristiques ressortiront à la lecture de la description d'un mode dé réalisation de l'invention donné à titre indicatif mais non limitatif ainsi que du dessin annexé sur lequel
la figure 1 est une vue de côté schématique du dispositif selon l'invention.Other advantages and characteristics will become apparent on reading the description of an embodiment of the invention given by way of indication but not limitation as well as the attached drawing in which
Figure 1 is a schematic side view of the device according to the invention.

La figure 2 est une autre vue du dispositif représenté sur la figure 1. FIG. 2 is another view of the device shown in FIG. 1.

Le dispositif selon l'invention et représenté sur-les figures comprend un châssis 1 monté sur des roues 2 et un carter 3 fermé sur au moins trois côtés. Dans le carter 3 sont disposés des moyens de projection d'un fluide tel que de l'eau sous pression, ces moyens comportant notamment une rampe 4 de buses 5 aptes à délivrer des jets 6 qui, en fonction de leur utilisation, peuvent être sous la forme d'un jet dit en crayon ou d'un jet étalé en triangle. La rampe 4 est montée sur un timon 7 susceptible d'être incliné par rapport à la verticale afin de déterminer l'angle d'impact 8 du ou des jets 6 sur la surface à nettoyer 9. Les moyens de montage à inclinaison variable du timon 7 sont connus des spécialistes et ne seront donc pas décrits dans le détail. Le timon 7 est creux et raccordé par une conduite flexible 10 à une source de fluide sous pression telle qu'une pompe, non représentée.Sur le timon 7 est montée une poignée de commande 11 de l'admission du fluide sous pression et de l'inclinaison du timon 7. The device according to the invention and shown in the figures comprises a chassis 1 mounted on wheels 2 and a casing 3 closed on at least three sides. In the casing 3 are arranged means for projecting a fluid such as pressurized water, these means comprising in particular a ramp 4 of nozzles 5 capable of delivering jets 6 which, depending on their use, can be under the shape of a jet said in pencil or a jet spread out in triangle. The ramp 4 is mounted on a drawbar 7 capable of being inclined relative to the vertical in order to determine the angle of impact 8 of the jet (s) 6 on the surface to be cleaned 9. The mounting means with variable inclination of the drawbar 7 are known to specialists and will therefore not be described in detail. The drawbar 7 is hollow and connected by a flexible pipe 10 to a source of pressurized fluid such as a pump, not shown. On the drawbar 7 is mounted a control handle 11 for admitting the pressurized fluid and the drawbar 7.

A l'intérieur du carter fermé 3 débouchent des moyens de récupération du fluide chargé de déchets, en l'occurence de l'eau usée, comprenant un suceur 12 dont la tête d'aspiration 13 comporte une face inférieure 14 effleurant le sol 9. De préférence, la tête d'aspiration présente une forme elliptique mais il va de soi que d'autres formes peuvent être utilisées. Inside the closed casing 3 open means for recovering the waste-laden fluid, in this case used water, comprising a nozzle 12 whose suction head 13 has a lower face 14 touching the ground 9. Preferably, the suction head has an elliptical shape, but it goes without saying that other shapes can be used.

Le suceur. 12 est relié par une conduite souple 15 à une bâche ou autre réservoir non représenté de l'eau usée, lequel réservoir peut être soit une citerne de stockage d'eau usée soit une cuve de régénération de l'eau qui peut alors être utilisée à nouveau par le dispositif de lavage de la présente invention.The squeegee. 12 is connected by a flexible pipe 15 to a tarpaulin or other tank (not shown) for waste water, which tank can be either a waste water storage tank or a water regeneration tank which can then be used for new by the washing device of the present invention.

La tête d'aspiration 13 est de préférence située à une faible distance des points d'impact des jets de lavage, par exemple entre 3 et 35 mm et mieux encore entre 5 et 25 mm. The suction head 13 is preferably located a short distance from the points of impact of the washing jets, for example between 3 and 35 mm and better still between 5 and 25 mm.

La rampe de jets 4 projette sur le sol à nettoyer de l'eau sous pression. Dès leur impact sur le sol, les jets d'eau 6 éclatent en éclaboussures qui sont retenues par les parois du carter 3 et aussitôt aspirées par le suceur 12 pour être évacuées, avec les crasses et autres saletés qu'elles transportent vers la bâche de récupération. The jet ramp 4 projects onto the ground to clean pressurized water. As soon as they hit the ground, the water jets 6 burst into splashes which are retained by the walls of the casing 3 and immediately sucked up by the squeegee 12 to be evacuated, with the grime and other dirt they transport to the tarpaulin of recovery.

Il est à noter que les buses génératrices des jets fixés sur la rampe 4 sont interchangeables afin de permettre un choix approprié de formes et de débits desdits jets. De même, les angles d'impact des jets sur le sol sont déterminés par le positionnement de la rampe et peuvent varier entre 5 et 90 degrés, la longueur desdits jets variant par exemple entre 2 et 20 cm. It should be noted that the nozzles generating the jets fixed on the ramp 4 are interchangeable in order to allow an appropriate choice of shapes and flow rates of said jets. Similarly, the angles of impact of the jets on the ground are determined by the positioning of the ramp and can vary between 5 and 90 degrees, the length of said jets varying for example between 2 and 20 cm.

Toutes ces indications, données à titre d'exemple non limitatif sont adaptées à des débits horaires de un à trente m3 sous des pressions de 10 à 200 bars mais peuvent être modifiées en fonction des caractéristiques du nettoyage à effectuer. All these indications, given by way of nonlimiting example, are adapted to hourly flow rates of one to thirty m3 at pressures of 10 to 200 bars but can be modified according to the characteristics of the cleaning to be carried out.

De même, ces données peuvent être modifiées lorsque la surface à nettoyer est en mouvement et le dispositif fixe. Likewise, these data can be modified when the surface to be cleaned is in motion and the device is fixed.

Une application intéressante mais non la seule, est le nettoyage des terrains de tennis réalisés en "bétons poreux". An interesting but not the only application is the cleaning of tennis courts made of "porous concrete".

Bien entendu, l'invention n'est nullement limitée au mode de réalisation de l'exemple décrit et représenté, elle est susceptible de nombreuses variantes accessibles à l'homme de l'art, suivant les applications envisagées et sans s'écarter pour cela du cadre de l'invention.  Of course, the invention is in no way limited to the embodiment of the example described and shown, it is capable of numerous variants accessible to those skilled in the art, depending on the applications envisaged and without departing from it of the scope of the invention.
