The electricity connection to the compressed air supply and the liquid pump is controlled by a timing programmer (14) to execute one or more cleaning sequences during cooking.

Description

La présente invention concerne les installations de nettoyage automatique des hottes aspirantes de cuisines, qui utilisent une solution de traitement contenant des micro-organismes non pathogènes aptes à dégrader notamment les graisses ou les huiles provenant des vapeurs ou fumées de cuisson.The present invention relates to automatic cleaning installations for kitchen extractor hoods, which use a treatment solution containing non-pathogenic micro-organisms capable of degrading in particular fats or oils from cooking vapors or fumes.

On connaít déjà, notamment par les documents US-B-6 274 375, ou encore EP-A-0 874 199 des installations de nettoyage de hottes de cuisine utilisant des solutions de traitement contenant des micro-organismes non pathogènes.We already know, especially from documents US-B-6,274,375, or EP-A-0 874 199 installations for cleaning range hoods using treatment solutions containing non-pathogenic microorganisms.

Mais les installations correspondantes ont une structure relativement complexe ; elles n'ont pas une efficacité optimale et elles nécessitent l'utilisation de quantités relativement importantes de produits de traitement, lesquels produits sont bien souvent assez onéreux.But the corresponding facilities have a relatively structure complex; they are not optimal and they require the use of relatively large quantities of treatment products, which products are often quite expensive.

La présente invention propose une installation de nettoyage originale visant à remédier à ces différents inconvénients.The present invention provides an original cleaning installation aimed at remedy these various drawbacks.

L'installation conforme à la présente invention comprend au moins une buse venturi de brumisation, munie de moyens qui permettent sa fixation sur une paroi de la hotte de cuisine que l'on désire équiper, laquelle buse est reliée à une source d'air comprimé et à une réserve de solution de traitement pour assurer l'aspiration automatique de ladite solution et sa diffusion sous forme de brouillard dans ladite hotte, ladite source d'air comprimé étant contrôlée par un système programmateur permettant de programmer une ou plusieurs séquences de nettoyage en dehors des périodes d'utilisation de la cuisine.The installation according to the present invention comprises at least one nozzle misting venturi, provided with means which allow its attachment to a wall of the range hood that you want to equip, which nozzle is connected to an air source tablet and a supply of treatment solution to ensure aspiration automatic of said solution and its diffusion in the form of mist in said hood, said source of compressed air being controlled by a scheduling system allowing to program one or more cleaning sequences outside the kitchen use periods.

La structure de cette installation est très simple ; et l'utilisation d'une buse venturi de brumisation assure l'atomisation des particules de solution de traitement pour former un brouillard à l'intérieur de la hotte, conférant au système de nettoyage une efficacité optimale et limitant les quantités de produit nécessaires.The structure of this installation is very simple; and the use of a nozzle misting venturi ensures atomization of the treatment solution particles to form a mist inside the hood, giving the cleaning system optimal efficiency and limiting the quantities of product required.

De préférence, la buse venturi de brumisation est fixée sur l'une des parois de côtés de la hotte.Preferably, the misting venturi nozzle is fixed to one of the walls of sides of the hood.

Selon un mode de réalisation préféré, l'installation comporte - une source d'air comprimé en forme de groupe motocompresseur électrique relié à la buse venturi de brumisation au moyen d'une tubulure d'amenée d'air, et - une réserve de solution de traitement reliée à ladite buse par l'intermédiaire d'une tubulure d'amenée de liquide.According to a preferred embodiment, the installation comprises - an air source compressed in the form of an electric compressor unit connected to the venturi nozzle of misting by means of an air intake tube, and - a reserve of solution of treatment connected to said nozzle by means of a liquid supply pipe.

Selon encore une forme de réalisation préférée, la tubulure d'amenée de la solution à injecter aboutit au niveau de la buse venturi sous la tubulure d'amenée d'air, pour favoriser le retour par simple gravité de la solution de traitement dans la réserve lors de l'arrêt du groupe motocompresseur, et la vidange de ladite buse. According to yet another preferred embodiment, the supply pipe of the solution to be injected ends up at the venturi nozzle under the air supply pipe, to favor the return by simple gravity of the treatment solution in the reserve when the power unit stops, and the said nozzle is emptied.

Selon un mode de réalisation particulièrement avantageux, la réserve de solution de traitement, ainsi que le groupe motocompresseur, sont disposés au même niveau horizontal ou sensiblement au même niveau horizontal que la buse venturi, en particulier pour limiter les pertes de charges.According to a particularly advantageous embodiment, the reserve of treatment solution, as well as the compressor unit, are arranged at the same horizontal level or substantially the same horizontal level as the venturi nozzle, in particularly to limit pressure losses.

Selon encore une autre particularité, l'installation comporte des moyens qui permettent de déclencher de façon manuelle une séquence de nettoyage de la hotte ; ces moyens se présentent avantageusement sous la forme d'un interrupteur monté en parallèle avec le système programmateur.According to yet another feature, the installation includes means which allow manual initiation of a hood cleaning sequence; these means are advantageously in the form of a switch mounted in parallel with the programming system.

D'autre part, le groupe motocompresseur, le système programmateur et éventuellement l'interrupteur pour déclencher manuellement le nettoyage, sont situés dans un module en forme de coffret disposé à côté du réservoir de solution de traitement, l'ensemble étant positionné à proximité de la hotte dans un local attenant approprié.On the other hand, the compressor unit, the programming system and possibly the switch to manually trigger cleaning, are located in a box-shaped module placed next to the solution tank treatment, the assembly being positioned near the hood in an adjoining room appropriate.

Si cela s'avère nécessaire, une pompe électrique peut être utilisée pour favoriser l'amenée de la solution de traitement jusqu'à la buse venturi de brumisation ; cette pompe est avantageusement alimentée en électricité après le système programmateur de manière à être activée simultanément au groupe motocompresseur.If necessary, an electric pump can be used to favor the supply of the treatment solution to the venturi misting nozzle; this pump is advantageously supplied with electricity after the system programmer so as to be activated simultaneously with the compressor unit.

Mais l'invention sera encore illustrée, sans être aucunement limitée, par la description suivante d'un mode de réalisation particulier, donné uniquement à titre indicatif, en association avec le dessin annexé qui illustre l'installation de nettoyage sous forme schématique.However, the invention will be further illustrated, without being in any way limited, by the following description of a particular embodiment, given only as indicative, in association with the attached drawing which illustrates the cleaning installation in schematic form.

La figure annexée montre une hotte aspirante 1 placée au-dessus d'un piano de cuisson 2 et équipée du dispositif de nettoyage 3 conforme à la présente invention.The attached figure shows an extractor hood 1 placed above a piano 2 and equipped with the cleaning device 3 according to the present invention.

De manière classique, la hotte 1 comprend un habillage longitudinal 4 fermé par des parois de côtés 5 et par une face de dessous 6. L'habillage longitudinal 4 est généralement réalisé en tôle d'inox, tout comme les parois de côtés 5 ; la face de dessous 6 peut être en forme de grille associée à un système de filtre(s).
Cette hotte 1 intègre un système de ventilation en forme de turbine, non représentée, qui permet l'aspiration des fumées, vapeurs et autres provenant du piano de cuisson 2 par la face de dessous 6, et qui permet leur évacuation par un conduit de sortie 8, placé généralement au centre de l'habillage longitudinal 4.Conventionally, the hood 1 comprises a longitudinal covering 4 closed by side walls 5 and by a bottom face 6. The longitudinal covering 4 is generally made of stainless steel sheet, just like the side walls 5; the underside 6 may be in the form of a grid associated with a filter system (s).
This hood 1 incorporates a turbine-shaped ventilation system, not shown, which allows the suction of fumes, vapors and the like coming from the cooking piano 2 by the underside 6, and which allows their evacuation by an outlet duct. 8, generally placed in the center of the longitudinal covering 4.

Le dispositif de nettoyage 3 conforme à l'invention est constitué d'un système injecteur 10 en forme de buse venturi de brumisation, de type air/liquide, relié, d'une part, à une réserve 11 de solution de traitement 12, et d'autre part à une source d'air comprimé 13 dont l'alimentation électrique est contrôlée par un système programmateur 14.The cleaning device 3 according to the invention consists of a system injector 10 in the form of a venturi misting nozzle, of the air / liquid type, connected, of a firstly, to a reserve 11 of treatment solution 12, and secondly to an air source compressed 13 whose power supply is controlled by a system programmer 14.

La buse venturi 10 est fixée à l'intérieur de la hotte 1, sur l'une de ses parois de côtés 5, par exemple au centre de ladite paroi. Elle est adaptée pour assurer l'atomisation de la solution de traitement 12 dans l'air et former ainsi un brouillard de liquide de traitement dans le volume interne de la hotte.
Cette buse 10 est reliée au réservoir de liquide 11 par une tubulure d'amenée 15, et à la source d'air comprimé 13 par une tubulure d'amenée 16. Ces deux tubulures 15 et 16 sont avantageusement réalisées en cuivre.The venturi nozzle 10 is fixed inside the hood 1, on one of its side walls 5, for example in the center of said wall. It is suitable for atomizing the treatment solution 12 in the air and thus forming a mist of treatment liquid in the internal volume of the hood.
This nozzle 10 is connected to the liquid reservoir 11 by a supply pipe 15, and to the source of compressed air 13 by a supply pipe 16. These two pipes 15 and 16 are advantageously made of copper.

Sur la partie arrière de la buse venturi 10, l'arrivée de la tubulure d'amenée de liquide 15 est placée sous l'arrivée de la tubulure d'amenée d'air comprimé 16, pour favoriser le retour du liquide de traitement 12 dans la réserve 11, et la vidange de ladite buse 10, lors de l'arrêt de la source d'air comprimé 13.On the rear part of the venturi nozzle 10, the arrival of the supply pipe of liquid 15 is placed under the inlet of the compressed air supply pipe 16, to favor the return of the treatment liquid 12 in the reserve 11, and the emptying of said nozzle 10, when the compressed air source 13 stops.

La solution de traitement 12 placée dans la réserve 11 en forme de flacon est une solution biotechnologique « prêt à l'emploi » renfermant des micro-organismes non pathogènes aptes à dégrader les particules de graisse, huile et autres provenant des fumées ou vapeurs de cuisine, et qui se sont déposées sur les parois internes de la hotte, ou sur les accessoires intégrés (filtre(s), turbine, conduit de sortie). Ces micro-organismes assurent la transformation des matières grasses en éléments assimilables dans le cycle biologique naturel et provoquent une séparation de la chaíne de carbone rendant ainsi les résidus solubles dans l'eau.
Le liquide en question est avantageusement une solution de microorganismes « prêt à l'emploi » commercialisée sous la dénomination « NU VENT » (Marque déposée par le Groupe MIKAAN), par la Société INNU-SCIENCE, Boulevard Nobel, Sainte-JULIE QUÉBEC - CANADA. Le flacon/réserve 11 peut avoir une contenance de l'ordre de 4 à 20 litres.The treatment solution 12 placed in the reserve 11 in the form of a bottle is a “ready-to-use” biotechnological solution containing non-pathogenic microorganisms capable of degrading the particles of grease, oil and others originating from cooking fumes or vapors. , and which are deposited on the internal walls of the hood, or on the integrated accessories (filter (s), turbine, outlet duct). These microorganisms ensure the transformation of fats into assimilable elements in the natural biological cycle and cause a separation of the carbon chain thus making the residues soluble in water.
The liquid in question is advantageously a solution of microorganisms "ready to use" marketed under the name "NU VENT" (Trademark registered by the MIKAAN Group), by the Company INNU-SCIENCE, Boulevard Nobel, Sainte-JULIE QUÉBEC - CANADA . The bottle / reserve 11 can have a capacity of the order of 4 to 20 liters.

La source d'air comprimé 13 se présente sous la forme d'un groupe motocompresseur électrique alimenté au moyen d'un câble 18 relié au secteur 19. La liaison du câble 18 au secteur 19 s'effectue par l'intermédiaire du système programmateur 14 et d'un interrupteur 20, montés en parallèle.
Le groupe motocompresseur 13 peut être du type à piston ; il permet l'envoi dans la tubulure 16 d'un flux d'air à un débit de l'ordre de 30 litres par minute.The source of compressed air 13 is in the form of an electric compressor unit supplied by means of a cable 18 connected to the sector 19. The connection of the cable 18 to the sector 19 takes place via the programming system 14 and a switch 20, mounted in parallel.
The compressor unit 13 can be of the piston type; it allows the sending into the tube 16 of an air flow at a rate of the order of 30 liters per minute.

L'interrupteur 20 permet le déclenchement manuel, à volonté, de séquences de nettoyage de la hotte. Le système programmateur 14 permet de programmer dans le temps une ou plusieurs séquences de nettoyage, en particulier en dehors des périodes d'utilisation de la cuisine, par exemple à la fin de chaque journée, ou la nuit.
Le programmateur 14 peut être un système très simple de type standard, muni de broches mâles permettant la connexion à une prise électrique classique, et de broches femelles permettant la réception du câble de branchement provenant du groupe motocompresseur.
La programmation s'effectue à partir d'un clavier de commande situé sur la face avant de l'appareil.Switch 20 allows manual triggering, at will, of hood cleaning sequences. The scheduler system 14 makes it possible to program one or more cleaning sequences over time, in particular outside the periods of use of the kitchen, for example at the end of each day, or at night.
The programmer 14 can be a very simple system of standard type, provided with male pins allowing the connection to a conventional electrical outlet, and female pins allowing the reception of the connection cable coming from the compressor unit.
Programming is carried out using a control keyboard located on the front of the device.

Le motocompresseur 13, l'interrupteur 20 et le programmateur 14 sont avantageusement placés dans un coffret de réception 21 positionné à côté du réservoir 11 de liquide de traitement 12. Le réservoir de liquide 11 et le coffret 21 sont disposés à proximité de la hotte 1, si possible dans un local annexe approprié (la cloison séparative correspondante est schématisée par la ligne pointillée 22).The compressor 13, the switch 20 and the programmer 14 are advantageously placed in a receiving box 21 positioned next to the tank 11 of treatment liquid 12. The liquid reservoir 11 and the box 21 are arranged near hood 1, if possible in an appropriate annex room (the bulkhead corresponding separator is shown schematically by the dotted line 22).

De préférence, le flacon 11 de solution de traitement se situe au même niveau ou sensiblement au même niveau que la buse de brumisation 10, c'est-à-dire dans le même plan horizontal, ou sensiblement dans le même plan horizontal, tout comme le groupe motocompresseur 13, de manière à limiter au maximum les pertes de charges.Preferably, the bottle 11 of treatment solution is located at the same level or substantially at the same level as the misting nozzle 10, that is to say in the same horizontal plane, or substantially in the same horizontal plane, just like the compressor unit 13, so as to limit pressure losses as much as possible.

Si besoin est, une pompe électrique 23, de type péristaltique, peut être placée sur la tubulure 15, alimentée en électricité après l'interrupteur 20 ou le programmateur 14 pour être activée simultanément au groupe motocompresseur 13. Sur le schéma annexé, on remarque le câble 24 d'alimentation de la pompe 23, entre ladite pompe et le programmateur 14.If necessary, an electric pump 23, of the peristaltic type, can be placed on the pipe 15, supplied with electricity after the switch 20 or the programmer 14 to be activated simultaneously with the compressor unit 13. In the diagram annexed, there is the cable 24 for supplying the pump 23, between said pump and the programmer 14.

On notera que si le conduit de sortie 8 n'est pas centré sur la longueur de la hotte 1, il sera préférable de fixer la buse de brumisation 10 sur la paroi de côté 5 la plus éloignée dudit conduit 8, pour optimiser la répartition de la solution de traitement.
En tout état de cause, et en fonction des besoins, on peut envisager d'équiper la hotte 1 d'une pluralité de buses 10.It will be noted that if the outlet duct 8 is not centered on the length of the hood 1, it will be preferable to fix the misting nozzle 10 on the side wall 5 furthest from said duct 8, to optimize the distribution of the treatment solution.
In any event, and depending on the needs, it is possible to envisage equipping the hood 1 with a plurality of nozzles 10.

Le programmateur 14 peut par exemple être paramétré pour réaliser des injections de produit pendant quelques minutes chaque jour après le service. Par exemple, on peut envisager des temps de brumisation compris entre 3 et 15 minutes par jour. Ce type de traitement peut entraíner une consommation raisonnable de produit de traitement, de l'ordre de 50 à 150 ml par jour, ce qui permet d'obtenir un intérieur de hotte en permanence propre et exempt d'odeurs, ceci à un coût très intéressant. En tout état de cause la durée du traitement sera fonction de la grandeur de la hotte et de son encrassement. L'élimination des résidus internes s'effectue par ventilation.The programmer 14 can for example be configured to carry out product injections for a few minutes each day after service. Through example, we can consider misting times between 3 and 15 minutes per day. This type of treatment can lead to a reasonable consumption of treatment product, of the order of 50 to 150 ml per day, which makes it possible to obtain a permanently clean and odor-free hood interior at a very low cost interesting. In any event, the duration of treatment will depend on the size the hood and its clogging. Internal residues are removed by ventilation.

On obtient en conséquence un système de nettoyage simple, efficace et économique, adaptable très facilement à toutes les installations, qui améliore la sécurité et l'hygiène quotidienne et qui performe le système d'extraction (hotte, turbine...).This results in a simple, effective and efficient cleaning system. economical, easily adaptable to all installations, which improves the daily safety and hygiene and which performs the extraction system (hood, turbine...).

Bien entendu, la présente invention peut s'appliquer de la même manière aux différents systèmes d'extraction connus, comme par exemple les plafonds filtrants.Of course, the present invention can be applied in the same way to various known extraction systems, such as filter ceilings.
