Description

-1 La présente invention concerne un lave-vaisselle à ultra-sons, destinée-1 The present invention relates to an ultrasonic dishwasher, intended

à réduire le temps de lavage, et faire des économies d'énergie en ramenant le cycle de lavage à un quart de la durée d'un cycle normal. Le concept présente un autre système de lavage, destiné aux nettoyages d' ustensiles divers et variés. Et plus particulièrement mais non exclusivement, un système de nettoyage à ultra-sons non immergé. Nous savons par le brevet " EP 0 887 041 A2 ", que l'appareil comporte un système ultra-sons. La dite application est restreinte, du fait que tout les ustensiles doivent être impérativement immergés dans un bac pour le lavage en ultra-sons. On trouve 10 également dans certains brevets " EP 0 396 363 A2 et FR 2 795 620 ", des  reduce washing time, and save energy by reducing the washing cycle to a quarter of the duration of a normal cycle. The concept presents another washing system, intended for cleaning various and varied utensils. And more particularly, but not exclusively, a non-submerged ultrasonic cleaning system. We know from patent "EP 0 887 041 A2" that the device includes an ultrasound system. Said application is restricted, since all the utensils must be immersed in a tank for washing with ultrasound. Also found in certain patents "EP 0 396 363 A2 and FR 2 795 620",

La présente invention vise à proposer un système ultra-sons, qui permette l'injection 15 d'eau ou d'un liquide chargé d'ultra-sons à travers plusieurs buses situées sur le ou les balais de lavage; afin de nettoyer efficacement les ustensiles, et de réduire par la même leur temps de lavage. L'avantage de notre système, c'est qu'il ne nécessite plus de plonger obligatoirement les ustensiles dans un bain. Le ou les balais selon l'invention comportent deux parois, dont l'une étanche ou se trouve les capteurs ultra20 sons, l'autre étant la paroi percée de buses par laquelle est injecté le liquide qui se  The present invention aims to provide an ultrasound system, which allows the injection of water or a liquid charged with ultrasound through several nozzles located on the washing brush (es); in order to effectively clean the utensils, and at the same time reduce their washing time. The advantage of our system is that it no longer requires you to immerse the utensils in a bath. The brush or brushes according to the invention have two walls, one of which is sealed or the ultrasonic sensors are located, the other being the wall pierced with nozzles through which the liquid which is injected is injected.

charge alors d'ultra-sons, et rend ainsi le lavage d'autant plus efficace.  then loads ultrasounds, and thus makes washing all the more effective.

Pour la réalisation préférée du système, le ou les balais cités se trouvent traversés dans leurs parois étanches par le résonateur ultrasons. Du fait de la proximité entre le résonateur ultra-sons et la paroi percée de buses, linjection du liquide sous pression 25 est alors chargée d'ultra-sons, ce qui permet notamment une complète efficacité du  For the preferred embodiment of the system, the cited brush or brushes are crossed in their sealed walls by the ultrasonic resonator. Due to the proximity between the ultrasonic resonator and the wall pierced with nozzles, the injection of the pressurized liquid 25 is then charged with ultrasound, which in particular allows complete efficiency of the

lavage des ustensiles.washing utensils.

Le ou les balais peuvent être de dimensions variés, à condition que leurs rotations ne  The brush (es) can be of various dimensions, provided that their rotations do not

se trouvent pas stoppées par les parois du lave-vaisselle.  are not blocked by the walls of the dishwasher.

Cela dit, le respect des proportions des cavités doit être effectives. Les buses sur le ou 30 les balais peuvent être disposées de manières et de formes différentes.  That said, the respect of the proportions of the cavities must be effective. The nozzles on the brush or brushes can be arranged in different ways and shapes.

L'avantage, c'est que l'on peut facilement adapter notre système sur tout types de  The advantage is that we can easily adapt our system to all types of

lave-vaisselle déjà existant.already existing dishwasher.

Pour le modèle de balais à arbre central, nous respecterons l'équidistance entre les  For the central shaft brush model, we will respect the equidistance between the

côtés et le centre. Celui-ci peut ainsi tourner sur son axe central sans être en contact 35 avec les parois de la machine.  sides and center. The latter can thus rotate on its central axis without being in contact with the walls of the machine.

Pour le modèle à deux balais, chaque axe qui les compose sera fixé dans un angle du lave-vaisselle et se trouve alors opposés, de sorte que les balais fassent leurs cycles en  For the model with two brushes, each axis which composes them will be fixed in a corner of the dishwasher and will then be opposite, so that the brushes cycle in

quart de tour.quarter turn.

-2 Nous privilégions le système à deux balais, car en décrivant un quart de tour chacun les balais se croisent en passant l'un sur l'autre sans se toucher, à un intervalle d'environ cinq millimètres minimum. Les passages successifs forment alors au centre des deux balais, une zone que l'on nommera " lavage intensif ", pour ustensiles très sales. A savoir aussi, que le lavage peut être rendu encore plus efficace, en amenant le liquide de lavage à une température n'excédant pas trente cinq degrés Celsius. Le liquide est injecté dans le ou les balais et ne peut sortir du lavevaisselle, car l'arbre les  -2 We favor the two-brush system, because by describing a quarter turn each the brushes cross by passing one over the other without touching, at an interval of about five millimeters minimum. The successive passages then form in the center of the two brushes, an area which will be called "intensive washing", for very dirty utensils. Also know that washing can be made even more effective, by bringing the washing liquid to a temperature not exceeding thirty five degrees Celsius. The liquid is injected into the brush (es) and cannot come out of the dishwasher, because the shaft

retenant est muni d'un joint spi qui assure une étanchéité absolument nécessaire.  retaining is provided with a spi joint which ensures an absolutely necessary sealing.

Donc ce système est plus efficace.So this system is more efficient.

Le générateur d'ultra-sons sera susceptible de produire la puissance demandée, (plus  The ultrasonic generator will be capable of producing the requested power, (more

les ustensiles seront sales, en conséquence on augmentera la puissance).  the utensils will be dirty, consequently the power will be increased).

Cela va de soit, que les parois du lave-vaisselle seront évidemment isolées de mousse  It goes without saying, that the walls of the dishwasher will obviously be insulated with foam

stoppant les nuisances occasionnées par ce système.  stopping the nuisance caused by this system.

La rotation de l'arbre est assurée par roulement à billes, à aiguilles, ou autres.  The shaft is rotated by ball, needle, or other bearings.

Quant au pivotement du ou des balais, il peut se faire par l'injection de liquide sous  As for the pivoting of the brush (es), it can be done by injecting liquid under

pression, par tout autres moyens électriques, électromécaniques, ou mécaniques.  pressure, by any other electrical, electromechanical, or mechanical means.

Enfin, nous prévoyons la réduction du temps de lavage d'une durée habituelle  Finally, we plan to reduce the washing time by a usual duration

moyenne d'environ une heure, à celle d'un cycle efficace de quinze minutes.  an average of about an hour, that of an effective fifteen-minute cycle.

Par conséquence, il y aura une économie d'eau et d'énergie.  As a result, there will be a saving of water and energy.

La figure A et B représente en coupe le dispositif de linvention à balai simple (3).  Figure A and B shows in section the device of the invention with a simple brush (3).

Nous avons un balai (3) fixé en son centre par un arbre (1), celui-ci peut avoir deux 25 types de rotations (5), soit la rotation vers la droite ou vers la gauche (5).Le balai (3) peut recevoir différentes formes de buses (2).Néanmoins, la rotation (5) laisse en certains endroits des carences de lavage, donc ce système représente des lacunes qui limitent le nettoyage (6).L'arbre (1) peut-être actionné par le débit du fluide (18), ou  We have a broom (3) fixed in its center by a shaft (1), this one can have two types of rotations (5), either rotation to the right or to the left (5). ) can receive different forms of nozzles (2).

Nous avons un balai (3) fixé sur son support (13) par roulement (9) avec joint spi (8), fixé en son centre par un arbre (1) maintenu par écrou (7). Le balai (3) est composé de deux cavités:l'une étanche (20), l'autre (21) permettant l'injection d'un fluide (18). 35 Dans la cavité étanche (20) se trouve le transducteur (14) qui le longe d'un bout à l'autre. Nous avons également sur le balai (3), des buses (2) qui peuvent être de  We have a brush (3) fixed on its support (13) by bearing (9) with oil seal (8), fixed in its center by a shaft (1) held by nut (7). The brush (3) is composed of two cavities: one sealed (20), the other (21) allowing the injection of a fluid (18). 35 In the sealed cavity (20) is the transducer (14) which runs along it from one end to the other. We also have on the broom (3), nozzles (2) which can be of

La figure C et D représente une vue non exhaustive d'un système de balais doubles  Figure C and D shows a non-exhaustive view of a double brush system

(c). (Nous privilégions un système qui soit le plus efficace).  (vs). (We favor a system which is the most efficient).

Nous avons un arbre (1) sur lequel est fixé un balai (3) percé sur toute sa longueur de buses (2) de différents modèles. Le balai (3) est fixé en son extrémité la plus évasée par un écrou (7) sur l'arbre (1). Nous préférons ce type de procédé dit à deux balais (figure C;D), car plus efficace dans sa fonction de lavage, nous trouvons donc une zone (19) dite de lavage intensif, du fait de la rotation (5) en quart de cercle que font chacun des balais (3). Par conséquent le nettoyage dans l'emploi d'un système à balai simple [figure A;B], est moins efficace par la présence de zones difficilement nettoyées (6). La figure C et D représente une vue en coupe non exhaustive d'un système à double balais (c). Nous avons deux balais (3) fixés sur un arbre (1) maintenus par roulement (9), (à billes, à aiguilles, etc), et par joint spi (8) enchâssés sur un support (13). L'arbre (1) se trouve verrouillé par un écrou (7). Les balais (3) sont fixés en leurs extrémités la plus évasée par l'arbre (1) dans un angle de l'appareil les recevant, chacun dans un coin opposé. Chaque balais (3) possède deux cavités, l'une étant étanche (20) qui est traversé par le résonateur ultra-sons (14). Dans l'autre cavité (21) se fait l'injection du liquide (18) qui se trouve alors éjecté par des buses (2) de différentes formes. Le transducteur ultra- sons (14) est alimenté par connectiques (11) s'alimentant sur le bloc ultra-sons (16). L'asservissement (17) se fait par le boîtier (17). Pour que les balais (3) exécutent leurs rotations (5), nous prévoyons entre autres  We have a shaft (1) on which is fixed a broom (3) drilled over its entire length of nozzles (2) of different models. The brush (3) is fixed at its most flared end by a nut (7) on the shaft (1). We prefer this type of process called two brushes (figure C; D), because more effective in its washing function, we therefore find a zone (19) called intensive washing, due to the rotation (5) in quarter circle made by each of the brushes (3). Consequently cleaning in the use of a simple brush system [figure A; B], is less effective by the presence of hardly cleaned areas (6). Figure C and D shows a non-exhaustive sectional view of a double brush system (c). We have two brushes (3) fixed on a shaft (1) maintained by bearing (9), (with balls, needles, etc.), and by spi joint (8) embedded on a support (13). The shaft (1) is locked by a nut (7). The brushes (3) are fixed at their most flared ends by the shaft (1) in a corner of the device receiving them, each in an opposite corner. Each brush (3) has two cavities, one being sealed (20) which is crossed by the ultrasonic resonator (14). In the other cavity (21) is injected the liquid (18) which is then ejected by nozzles (2) of different shapes. The ultrasound transducer (14) is powered by connectors (11) which feed on the ultrasound block (16). The control (17) is done by the housing (17). In order for the brushes (3) to rotate (5), we plan among other things

des fins de course à contact par aimants (15).  contact limit switches by magnets (15).

Notre système (figure C et D) rend le nettoyage des ustensiles incroyablement plus 30 efficace qu'un lavage traditionnel.  Our system (Figures C and D) makes cleaning utensils incredibly more efficient than traditional washing.

Lorsque le liquide (18) est entré en contact avec le capteur ultra-sons (14), qui est logé dans le compartiment étanche (20), le fluide est alors chargé d' ultra-sons (16) et se trouve donc éjecté par les buses (2), ce qui décuple considérablement l'efficacité du  When the liquid (18) has come into contact with the ultrasonic sensor (14), which is housed in the sealed compartment (20), the fluid is then charged with ultrasound (16) and is therefore ejected by nozzles (2), which greatly increases the efficiency of the
