Description

La présente invention concerne une hotte de cuisine qui permette de retenir les graisses des vapeurs et fumées provenant d'une cuisinière et comprenant au moins un filtre et des moyens permettant de nettoyer les filtres de la hotte en position de service et/ou pendant le fonctionnement de la hotte.The present invention relates to a kitchen hood that can retain grease vapors and fumes from a range and comprising at least one filter and means for cleaning the filters of the hood in the service position and / or during operation of the hood.

De telles hottes autonettoyantes sont décrites par exemple dans les documents CH 683 597 et CH 692 516 . Ce type de hotte comprend des moyens pour nettoyer le ou les filtres en continu et pendant l'utilisation de la hotte, c'est-à-dire pendant l'épuration des vapeurs graisseuses. Ces moyens de nettoyage sont en général agencés pour amener un produit de nettoyage dilué dans de l'eau jusqu'au filtre. L'eau mélangée au produit de nettoyage est par exemple véhiculée jusqu'aux filtres par des rampes ou des chariots mobiles.Such self-cleaning hoods are described for example in the documents CH 683 597 and CH 692,516 . This type of hood includes means for cleaning the filter (s) continuously and during use of the hood, that is to say during the purification of the fatty vapors. These cleaning means are generally arranged to bring a cleaning product diluted in water to the filter. The water mixed with the cleaning product is for example conveyed to the filters by ramps or mobile carriages.

Ces dispositifs présentent l'inconvénient d'utiliser une grande quantité d'eau afin de garantir un bon nettoyage des filtres. En moyenne, ces dispositifs nécessitent en effet 38 litres d'eau par cycle de nettoyage, la durée d'un cycle étant d'environ 3 minutes. Outre la quantité nécessaire, l'eau doit être chauffée à 55°C pour une plus grande efficacité de nettoyage, ce qui entraîne une importante consommation d'énergie. De plus, au vu de la grande quantité d'eau nécessaire pour amener le produit nettoyant au filtre, celui-ci s'en trouve grandement dilué. Ainsi, le produit nettoyant arrive aux filtres en faible quantité ce qui réduit sensiblement l'effet de dégraissage. La solution qui consisterait à augmenter la quantité de produit nettoyant au départ n'est cependant ni économique ni écologique.These devices have the disadvantage of using a large amount of water to ensure a good cleaning of the filters. On average, these devices require in fact 38 liters of water per cleaning cycle, the duration of a cycle being about 3 minutes. In addition to the required amount, the water must be heated to 55 ° C for greater cleaning efficiency, resulting in high energy consumption. In addition, in view of the large amount of water required to bring the cleaning product to the filter, it is greatly diluted. Thus, the cleaning product arrives at the filters in small quantities which substantially reduces the degreasing effect. The solution which would consist in increasing the amount of cleaning product initially is however neither economic nor ecological.

Finalement, un autre inconvénient des systèmes de nettoyage connus réside dans le fait que le mélange eau-produit nettoyant est injecté de façon continue pendant un certain laps de temps (en général 3 minutes). Cela provoque un effet de lavage peu efficace dans le sens où la première dépose de produit nettoyant se trouve immédiatement lavée par la suite du nettoyage. Le produit nettoyant n'a donc que très peu de temps d'action sur les filtres.Finally, another disadvantage of the known cleaning systems is that the water-cleaning agent mixture is injected continuously for a certain period of time (usually 3 minutes). This causes an inefficient washing effect in the sense that the first product deposit cleaner is immediately washed afterwards cleaning. The cleaning product therefore has very little action time on the filters.

Le but de la présente invention est de fournir une hotte de cuisine autonettoyante qui remédie aux inconvénients précités et qui soit efficace, tout en étant économe en eau et en produit nettoyant et qui permette un dégraissage des vapeurs et un nettoyage des filtres optimaux.The object of the present invention is to provide a self-cleaning kitchen hood which overcomes the aforementioned drawbacks and which is effective, while being economical in water and cleaning product and which allows a degreasing of the vapors and cleaning of the optimal filters.

La présente invention a pour objet une hotte de cuisine autonettoyante selon la revendication 1 ainsi qu'un procédé de nettoyage d'un filtre équipant une telle hotte autonettoyante selon la revendication 6.The present invention relates to a self-cleaning kitchen hood according to claim 1 and to a method of cleaning a filter fitted to such a self-cleaning hood according to claim 6.

The accompanying drawings illustrate schematically and by way of example an embodiment of a kitchen hood according to the invention.
  • The figure 1 is a side sectional view of the hood according to the invention.
  • The figure 2 is a front sectional view of the hood according to the invention.
  • The figure 3 is a view from above of a filter equipping the hood illustrated in figures 1 and 2 .
  • The figure 4 is a bottom view of the filter shown in the figure 3 .
  • The figure 5 is a sectional view of the filter illustrated in Figures 3 and 4 .

La hotte illustrée à la figure 1 comprend un caisson 1 ouvert dans sa partie inférieure et à l'intérieur duquel sont fixés un guide supérieur 2 et un guide inférieur 3.The hood shown in the figure 1 comprises a box 1 open in its lower part and inside which are fixed an upper guide 2 and a lower guide 3.

Les deux guides supérieur et inférieur 2, 3 définissent un passage 4 par lequel sont aspirées les vapeurs et fumées provenant d'une cuisinière (non illustrée) située sous la hotte. Les vapeurs et fumées peuvent être aspirées par tout moyen d'aspiration approprié bien connus de l'homme du métier comme par exemple un ventilateur extracteur 12 tel qu'illustré à la figure 2.The two upper and lower guides 2, 3 define a passage 4 through which are sucked the vapors and fumes from a stove (not shown) located under the hood. The vapors and fumes can be sucked by any suitable suction means well known to those skilled in the art such as for example an extractor fan 12 as illustrated in FIG. figure 2 .

Ce passage 4 débouche dans une chambre 5 délimitée dans le caisson 1. La chambre 5 comporte au moins un filtre 6 ainsi que des moyens de nettoyage dudit filtre.This passage 4 opens into a chamber 5 defined in the box 1. The chamber 5 comprises at least one filter 6 and means for cleaning said filter.

De préférence et comme illustré aux figures 3 à 5, le filtre 6 est un filtre à billes d'argile expansée composé d'un cadre 62, d'une grille supérieure 63 et d'une grille inférieure 64. Des billes d'argile expansée 65 sont placées dans le cadre 62 entre les grilles supérieure 63 et inférieure 64.Preferably and as illustrated in Figures 3 to 5 , the filter 6 is an expanded clay ball filter composed of a frame 62, an upper grid 63 and a lower grid 64. Expanded clay balls 65 are placed in the frame 62 between the grids upper 63 and lower 64.

La grille supérieure 63 est essentiellement plate, tandis que la grille inférieure 64 est cannelée permettant ainsi d'augmenter sa surface. La surface de contact entre le filtre 6 et les vapeurs et fumées de la cuisinière est ainsi augmentée conférant au filtre 6 une efficacité élevée.The upper grid 63 is essentially flat, while the lower grid 64 is grooved thus increasing its surface. The contact surface between the filter 6 and the vapors and fumes of the range is thus increased giving the filter 6 a high efficiency.

Les billes d'argile 65 du filtre 6 présentent quant à elles un diamètre suffisamment grand pour réduire la perte de charge lorsque l'air chargé de graisse traverse le filtre 6. De préférence, le diamètre des billes 65 est compris entre 15 et 20 mm. En réduisant la perte de charge, on réduit ainsi l'énergie nécessaire pour l'aspiration des vapeurs. De plus, plus le diamètre des billes 65 est grand plus elles sont faciles à nettoyer. L'épaisseur du lit de billes 65 dans le cadre 62 permet également de contrôler la perte de charge ainsi que l'efficacité du filtre 6. En effet, plus l'épaisseur est grande plus le dégraissage sera important. En outre, de préférence, les billes d'argile 65 présentent un pH acide, compris entre 5 et 5.5. Ce pH peut être obtenu par tout traitement approprié des billes 65 et notamment par tamponnage (trempage des billes dans une solution acide pour faire baisser leur pH naturel). Avec cette caractéristique, en fin de vie du filtre, après des cycles de lavage répétés utilisant un produit de nettoyage basique, dont le pH est généralement compris entre 9 et 9,5, les billes présentent un pH compris entre 6 et 6,5, l'acidité initiale des billes neutralisant le caractère basique du produit de nettoyage. Cela permet un retraitement et un recyclage des billes facilités.The clay beads 65 of the filter 6 have in turn a sufficiently large diameter to reduce the pressure drop when the fat-laden air passes through the filter 6. Preferably, the diameter of the balls 65 is between 15 and 20 mm . By reducing the pressure drop, it reduces the energy required for the aspiration of the vapors. In addition, the larger the diameter of the balls 65, the easier they are to clean. The thickness of the bed of balls 65 in the frame 62 also makes it possible to control the pressure drop and the efficiency of the filter 6. Indeed, the greater the thickness, the greater the degreasing will be important. In addition, preferably, the clay beads 65 have an acidic pH of between 5 and 5.5. This pH can be obtained by any appropriate treatment of the beads 65 and in particular by buffering (soaking the beads in an acid solution to lower their natural pH). With this characteristic, at the end of the life of the filter, after repeated washing cycles using a basic cleaning product, whose pH is generally between 9 and 9.5, the beads have a pH of between 6 and 6.5, the initial acidity of the beads neutralizing the basic character of the cleaning product. This allows reprocessing and recycling of the facilitated beads.

Dans une hotte de cuisine, le filtre est le coeur du système, le principal élément qui participe au dégraissage des vapeurs et des fumées provenant de la cuisinière. Cependant, plus le filtre est performant, plus vite il s'engraisse. C'est pourquoi il est nécessaire que la hotte de cuisine comprenne outre un filtre efficace, des moyens de nettoyage performants et qui permette de nettoyer le filtre efficacement et sans interrompre le fonctionnement de la hotte.In a kitchen hood, the filter is the heart of the system, the main element involved in the degreasing of vapors and fumes from the stove. However, the better the filter, the faster it grows. That is why it is necessary that the kitchen hood includes a filter effective, cleaning means effective and that cleans the filter effectively and without interrupting the operation of the hood.

Les moyens de nettoyage du filtre de la hotte selon l'invention comprennent une rampe d'alimentation supérieure 7 et une rampe d'alimentation inférieure 8 reliées chacune à une source d'alimentation (non illustrée) en eau, de préférence chauffée à environ 55°C. Les rampes d'alimentation supérieure et inférieure 7, 8 présentent chacune une portion en forme de U 71, 81, appelée piège à savon. Chacun des pièges à savon 71, 81 constitue respectivement une zone hors pression des rampes d'alimentation supérieure et inférieure 7, 8. Chacun des pièges à savon 71, 81 est relié via une vanne d'injection appropriée 72, 82 à un réservoir de produit nettoyant 91, 92, le produit nettoyant est en général une solution d'enzyme rendant les graisses hydrosolubles. Deux pompes 93, 94 sont agencées respectivement entre les réservoirs 91, 92 et les pièges à savon 71, 81 de manière à alimenter ceux-ci en produit nettoyant via les vannes d'injection 72, 82.The hood filter cleaning means according to the invention comprise an upper feed ramp 7 and a lower feed ramp 8 each connected to a feed source (not shown) in water, preferably heated to about 55.degree. ° C. The upper and lower feed ramps 7, 8 each have a U-shaped portion 71, 81, called a soap trap. Each of the soap traps 71, 81 respectively constitutes an off-pressure zone of the upper and lower feed ramps 7, 8. Each of the soap traps 71, 81 is connected via an appropriate injection valve 72, 82 to a reservoir of water. cleaning product 91, 92, the cleaning product is generally an enzyme solution making the fats water-soluble. Two pumps 93, 94 are respectively arranged between the tanks 91, 92 and the soap traps 71, 81 so as to supply them with cleaning product via the injection valves 72, 82.

A l'extrémité libre de la rampe d'alimentation supérieure 7 se trouve une première buse rotative 10 agencée pour asperger le filtre 6 par le haut. De même, à l'extrémité libre de la rampe d'alimentation inférieure 8 se trouve une seconde buse rotative 11 agencée pour asperger le filtre 6 par le bas.At the free end of the upper feed ramp 7 is a first rotary nozzle 10 arranged to spray the filter 6 from above. Similarly, at the free end of the lower feed ramp 8 is a second rotary nozzle 11 arranged to spray the filter 6 from below.

Chacune des rampes d'alimentation supérieure et inférieure 7, 8 est encore équipée d'une électrovanne 73, 83 permettant de contrôler le débit d'eau dans lesdites rampes depuis la source d'alimentation en eau.Each of the upper and lower feed ramps 7, 8 is further equipped with a solenoid valve 73, 83 for controlling the flow of water in said ramps from the water supply source.

La hotte de cuisine selon l'invention comprend en outre des moyens de commande 100 agencés pour commander les vannes d'injection 72, 82, les électrovannes 73, 83, les pompes 93, 94 et les moyens d'aspiration (ventilateur extracteur 12).The kitchen hood according to the invention further comprises control means 100 arranged to control the injection valves 72, 82, the solenoid valves 73, 83, the pumps 93, 94 and the suction means (extractor fan 12). .

Le fonctionnement de la hotte de cuisine selon l'invention va maintenant être décrit en détail.The operation of the kitchen hood according to the invention will now be described in detail.

En fonctionnement normal, le ventilateur extracteur 12 aspire les vapeurs et les fumées de la cuisinière qui traversent alors le filtre 6. De préférence et comme décrit ci-dessus, la construction du filtre 6, sa grille inférieure 64 cannelée et l'agencement et les caractéristiques des billes d'argiles 65 qu'il contient rend ledit filtre 6 très performant et l'air qui s'échappe du filtre 6 après l'avoir traversé est suffisamment propre pour être réutiliser dans un récupérateur de chaleur par exemple.In normal operation, the extractor fan 12 sucks the vapors and fumes from the range which then pass through the filter 6. Preferably and as described above, the construction of the filter 6, its grooved lower grill 64 and the arrangement and the characteristics of the clay beads 65 that it contains makes said filter 6 very efficient and the air escaping from the filter 6 after passing through it is sufficiently clean to be reused in a heat recovery unit for example.

Les moyens de commande sont programmés pour activer les moyens de nettoyage du filtre soit à intervalles réguliers soit sur demande de l'utilisateur. Un cycle de nettoyage se compose des étapes suivantes.The control means are programmed to activate the filter cleaning means either at regular intervals or at the request of the user. A cleaning cycle consists of the following steps.

Les moyens de commande activent d'abord les pompes 93, 94 qui injectent respectivement via les vannes d'injection 72, 82 une quantité prédéterminée de produit de nettoyage depuis les réservoirs 91, 92 jusque dans les pièges à savon 71, 81. De préférence, la quantité de produit de nettoyage injectée dans le piège à savon 71 de la rampe supérieure 7 est plus élevée que la quantité de produit de nettoyage injectée dans le piège à savon 81 de la rampe inférieure 8.The control means first activate the pumps 93, 94 which respectively inject via the injection valves 72, 82 a predetermined quantity of cleaning product from the tanks 91, 92 into the soap traps 71, 81. Preferably , the quantity of cleaning product injected into the soap trap 71 of the upper ramp 7 is higher than the quantity of cleaning product injected into the soap trap 81 of the lower ramp 8.

Dans une seconde étape, les moyens de commande activent le ventilateur extracteur 12 (si la hotte n'était pas déjà en fonction) et ouvrent chacune des électrovannes 73, 83 de sorte que l'eau sous pression provenant de la source d'alimentation circule dans chacune des rampes supérieure et inférieure 7, 8 respectivement. L'eau pousse alors le produit de nettoyage des pièges à savon 71, 81 jusqu'aux buses 10, 11 qui dispersent le mélange produit de nettoyage-eau sur les grilles supérieure et inférieure 63, 64 du filtre 6. De préférence, les moyens de commande ouvrent les électrovannes 73, 83 de façon successive en commençant par l'électrovanne 73 de la rampe supérieure 7.In a second step, the control means activate the extractor fan 12 (if the hood was not already in operation) and open each of the solenoid valves 73, 83 so that the pressurized water from the power source circulates. in each of the upper and lower ramps 7, 8 respectively. The water then pushes the cleaning product of the soap traps 71, 81 to the nozzles 10, 11 which disperse the cleaning product-water mixture on the upper and lower grids 63, 64 of the filter 6. Preferably, the means control valves 73, 83 open successively starting with the solenoid valve 73 of the upper ramp 7.

De part l'agencement des rampes d'alimentation 7, 8 et en particulier des pièges à savon 71, 81, le produit de nettoyage poussé par l'eau arrive en grande concentration sur le filtre 6. Ainsi, il n'est pas nécessaire que l'ouverture des électrovannes 73, 83 et donc le cycle de lavage soient prolongés. Selon la pression de l'eau à la sortie de la source d'alimentation et la longueur de la portion des rampes d'alimentation 7, 8 entre les pièges à savon 71, 81 et les buses 10, 11, le temps d'ouverture des électrovannes 73, 83 peut être de quelques dizaines de secondes, voire de préférence compris entre 4 et 6 secondes. Il est ainsi possible de réaliser d'importantes économies d'eau tout en assurant un dégraissage performant puisque la concentration du produit de nettoyage arrivant sur le filtre 6 est importante.Due to the arrangement of the feed ramps 7, 8 and in particular of the soap traps 71, 81, the cleaning product pushed by the water arrives in great concentration on the filter 6. Thus, it is not necessary that the opening of the solenoid valves 73, 83 and therefore the wash cycle are prolonged. According to water pressure at the outlet of the supply source and the length of the portion of the supply ramps 7, 8 between the soap traps 71, 81 and the nozzles 10, 11, the opening time of the solenoid valves 73, 83 may be a few tens of seconds, or preferably between 4 and 6 seconds. It is thus possible to achieve significant water savings while ensuring efficient degreasing since the concentration of the cleaning product arriving on the filter 6 is important.

Durant cette phase de dispersion du produit de nettoyage, l'aspiration engendrée par le ventilateur extracteur 12 est maintenue : en effet, l'aspiration permet de garder le produit de nettoyage à l'intérieur du filtre 6 par effet de sustentation augmentant le temps d'action dudit produit de nettoyage et donc l'efficacité du dégraissage.During this phase of dispersing the cleaning product, the suction generated by the extractor fan 12 is maintained: in fact, the suction makes it possible to keep the cleaning product inside the filter 6 by means of a lifting effect increasing the cleaning time. action of said cleaning product and thus the effectiveness of degreasing.

L'aspiration est ensuite coupée, les moyens de commande 100 stoppant le ventilateur extracteur 12, et les électrovannes 73, 83 des rampes supérieure et inférieure 7, 8 sont à nouveau ouvertes par les moyens de commande 100 pour permettre le rinçage du filtre. De préférence, le temps de rinçage est de 1 à 2 minutes.The suction is then cut off, the control means 100 stopping the extractor fan 12, and the solenoid valves 73, 83 of the upper and lower ramps 7, 8 are again opened by the control means 100 to allow rinsing of the filter. Preferably, the rinsing time is 1 to 2 minutes.

Les eaux usées, guidées par le guide inférieur 3, sont évacuées par des moyens d'évacuations prévus dans la partie inférieure de la chambre 5 et le cycle de lavage prend fin.The wastewater, guided by the lower guide 3, is evacuated by evacuation means provided in the lower part of the chamber 5 and the washing cycle ends.

La présente forme d'exécution a été décrite à titre indicatif, d'autres variantes pourraient évidement être envisagées sans sortir du cadre de l'invention.The present embodiment has been described for information only, other variants could of course be envisaged without departing from the scope of the invention.

En variante, les buses 10, 11 pourraient être montées sur des chariots mobiles leur imprimant un mouvement de va-et-vient pendant le cycle de lavage.Alternatively, the nozzles 10, 11 could be mounted on moving carriages reciprocating them during the wash cycle.

La hotte selon l'invention permet donc un dégraissage performant puisque le produit de nettoyage est distribué de manière concentrée sur le filtre. Il a pu être constaté que le produit de nettoyage arrive sur le filtre dix fois moins dilué que dans les hottes autonettoyantes connues citées précédemment. De plus, le produit de nettoyage est distribué selon deux directions sur le filtre, et avec l'aide des moyens d'aspiration, le temps d'action dudit produit est grandement augmenté (pas d'effet de lavage comme dans les hottes de l'art antérieur). En outre, la distribution ciblée du produit nettoyant permet de faire des économies sans perdre en efficacité en dosant précisément le produit. Cela a également un impact écologique puisque moins de polluants sont rejetés dans les eaux usées.The hood according to the invention thus allows efficient degreasing since the cleaning product is distributed in a concentrated manner on the filter. It has been found that the cleaning product arrives on the filter ten times less diluted than in the known self-cleaning hoods mentioned above. In addition, the cleaning product is distributed in two directions on the filter, and with the help suction means, the action time of said product is greatly increased (no washing effect as in hoods of the prior art). In addition, the targeted distribution of the cleaning product saves money without losing efficiency by precisely dosing the product. This also has an ecological impact since fewer pollutants are released into the wastewater.

La hotte selon l'invention permet également d'économiser l'eau, puisque le cycle de lavage ne dure plus que quelques dizaines de secondes contre quelques minutes dans l'art antérieur. Des économies d'énergie sont aussi envisageables: si l'encrassement des filtres n'est pas trop important (ce qui dépend du type de cuisine), il est possible d'utiliser de l'eau froide à la place d'une eau chauffée à 55°C.The hood according to the invention also saves water, since the washing cycle lasts more than a few tens of seconds against a few minutes in the prior art. Energy savings are also possible: if the clogging of the filters is not too important (which depends on the type of kitchen), it is possible to use cold water instead of heated water at 55 ° C.

La hotte selon l'invention possédant des moyens de nettoyage très efficace, il est possible de l'équiper de filtres performants qui même s'ils s'encrassent vite pourront être nettoyés efficacement et permettre un dégraissage optimal des vapeurs et des fumées chargées de graisse, qui, une fois filtrées, peuvent alors être récupérées et recyclées dans des systèmes de récupérations de l'énergie tels que des récupérateurs de chaleur rotatifs.The hood according to the invention having very effective cleaning means, it is possible to equip it with efficient filters which, even if they become dirty quickly, can be cleaned efficiently and allow optimal degreasing of the vapors and fumes laden with grease. which, once filtered, can then be recovered and recycled into energy recovery systems such as rotary heat recovery units.

En outre, au vu de ces moyens de nettoyage performant, la hotte selon l'invention pourra également être utilisée dans des conditions particulièrement difficiles comme dans des cuisines de type grillade, fast food ou asiatique dégageant des vapeurs particulièrement grasses.In addition, in view of these efficient cleaning means, the hood according to the invention can also be used in particularly difficult conditions such as in grilling, fast food or Asian type of cooking releasing particularly oily vapors.

Il a également été remarqué que la durée de vie d'un filtre équipant une hotte selon l'invention utilisée dans des conditions normales est augmentée, le filtre n'étant changé que pour des raisons de normes sanitaires.It has also been noted that the life of a filter equipping a hood according to the invention used under normal conditions is increased, the filter being changed only for reasons of sanitary standards.

La combinaison d'un filtre et de moyens de nettoyage dudit filtre très performants garantit aussi la propreté de l'ensemble de la hotte, en particulier des moyens d'aspiration, de la cheminée, mais également de l'air ambiant. Tous ces facteurs entraînent une diminution des risques d'incendie, une diminution du coût d'exploitation (économies d'eau, de produit nettoyant, d'énergie, récupération de chaleur...) et une augmentation du confort de l'utilisateur.The combination of a filter and cleaning means of said high-performance filter also ensures the cleanliness of the entire hood, especially the suction means, the chimney, but also the ambient air. All of these factors reduce the risk of fire, lower the cost operation (saving water, cleaner, energy, heat recovery ...) and increasing user comfort.
