Abstract
Description
L'objet de cette invention est un dispositif de récupération de l'énergie dispersée par les plans de cuisson et par les aliments en cours de cuisson, au moyen de dispositifs logés dans une hotte disposée au-dessus de la cuisinière.The object of this invention is a device for recovery of the energy dispersed by the plans of cooking and by the food being cooked, at by means of devices housed in a hood arranged above from the stove.
Le problème de l'économie d'énergie est sans doute l'un des plus vivement ressentis au 20e siècle; c'est un problème aux multiples aspects qui affecte tant les gouvernants que les citoyens, du point de vue des coûts sociaux et personnels, comme du point de vue de la conscience civique, puisque certains des problèmes écologiques du milieu dans lequel nous vivons sont déterminés ou accrus par une mauvaise utilisation de l'énergie.The problem of saving energy is undoubtedly one most keenly felt in the 20th century; it's a multifaceted problem that affects both rulers than citizens, from a cost perspective social and personal, as from the point of view of civic awareness, since some of the problems ecological of the environment in which we live are determined or increased by misuse of energy.
La production d'énergie, nous le savons, est possible selon de nombreux systèmes; ces systèmes comportent toujours un coût pour l'usager, coût facilement quantifiable par rapport au coût que l'usager supporte sous forme de dépense, par exemple pour la fourniture d'une quantité d'énergie donnée, qu'il s'agisse d'électricité, de carburant, de gaz, de charbon, de bois, etc.; mais qui est difficilement quantifiable dans toute une série de coûts dérivant de la consommation d'énergie, tels que, par exemple: le coût social dû à la pollution dérivant de la production de cette énergie, avec tous les problèmes et frais relatifs à la santé de la population; le coût de la dépollution; le coût social payé par la communauté pour les déboisements, etc.Energy production, we know, is possible according to many systems; these systems include always a cost for the user, cost easily quantifiable in relation to the cost that the user bears as an expense, for example for the supply of a given amount of energy, whether it's electricity, fuel, gas, coal, wood, etc .; but which is difficult to quantify in a whole series of costs deriving from the energy consumption, such as, for example: the cost pollution caused by the production of this energy, with all the problems and costs relating to population health; the cost of depollution; the social cost paid by the community for deforestation, etc.
Après des décennies de désintérêt, le problème de l'économie d'énergie est actuellement vivement ressenti, et nombreuses sont les recherches visant à obtenir une économie d'énergie ou à mieux utiliser l'énergie consommée, tout en réduisant la pollution, dans toute la mesure du possible.After decades of disinterest, the problem of energy saving is currently strongly felt, and there is much research aimed at get energy savings or better use the energy consumed, while reducing pollution, as much as possible.
Dans certains domaines, ces recherches ont abouti à un emploi plus rationnel de l'énergie, tandis que dans d'autres rien, ou presque, n'a été fait. In some areas, this research has resulted in a more rational use of energy, while in others almost nothing has been done.
En matière de restauration dans les foyers, dans les établissements publics, dans les restaurants d'entreprise, hospitaliers ou de grandes collectivités, on utilise quotidiennement une grande quantité d'énergie pour cuisiner les repas, mais jusqu'à présent aucun dispositif n'a été conçu pour permettre de récupérer l'énergie dispersée dans l'air, sous forme de chaleur, à travers la hotte aspirante, par les brûleurs et par les aliments en cours de cuisson.In terms of catering in homes, in public establishments, in restaurants corporate, hospital or large communities, a large amount is used daily energy to cook meals, but so far no device has been designed to allow recover the energy dispersed in the air, in the form of heat, through the extractor hood, through the burners and by the food being cooked.
L'objet de cette invention est un dispositif de récupération de l'énergie dispersée par les plans de cuisson et par les aliments pendant la cuisson.The object of this invention is a device for recovery of the energy dispersed by the plans of cooking and by food during cooking.
Selon cette invention, il est prévu que, à l'intérieur de la hotte aspirante placée au-dessus de la cuisinière, soit disposé un échangeur de chaleur dans lequel circule un fluide, alimenté au moyen d'un réservoir, et mis en circulation à l'intérieur de l'échangeur de chaleur, de préférence à l'aide d'une petite pompe; l'échangeur de chaleur, enveloppé par la chaleur qui monte des feux et par la vapeur des aliments en cours de cuisson, se réchauffe rapidement et transmet la chaleur au fluide, par exemple de l'eau, qui y circule; l'eau chauffée revient dans le réservoir et par une conduite ad hoc est dirigée vers les appareils utilisateurs.According to this invention, it is intended that, inside of the extractor hood placed above the cooker, a heat exchanger is placed in which circulates a fluid, supplied by means of a tank, and circulated inside the heat exchanger, preferably using a small pump; the heat exchanger, wrapped by the heat rising from the fires and from the steam food being cooked, heats up quickly and transmits heat to the fluid, for example water, who circulates there; the heated water returns to the tank and by an ad hoc conduct is directed to the user devices.
La circulation de chaleur, à l'intérieur de la hotte, est assurée et favorisée par le ventilateur de la hotte, et le rendement de l'installation est optimisé par un thermostat qui règle le fonctionnement de la pompe de circulation de l'eau.The circulation of heat, inside the hood, is ensured and favored by the fan of the hood, and the efficiency of the installation is optimized by a thermostat which regulates the operation of the water circulation pump.
Une soupape de sûreté maintient la pression à l'intérieur du réservoir dans les limites établies.A safety valve keeps the pressure at the interior of the tank within the established limits.
L'invention est illustrée ci-après, à titre de simple exemple non exhaustif, dans le dessin ci-joint qui montre, sous forme schématique, le dispositif visé par l'invention, installé dans une hotte de cuisine.The invention is illustrated below, by way of simple non-exhaustive example, in the attached drawing which shows, in schematic form, the device targeted by the invention, installed in a kitchen hood.
Comme l'illustre la figure, la hotte d'aspiration pour la cuisine à récupération de l'énergie thermique produite par les plans de cuisson, selon cette invention, est formée par une hotte (1) à l'intérieur de laquelle, selon les moyens connus, est installé un échangeur de chaleur (2), réalisé dans un matériau apte à retenir la chaleur (6) qui monte de la cuisinière (7) et à la transférer à l'eau qui circule à l'intérieur de l'échangeur de chaleur (2). L'échangeur de chaleur (2) est relié à un réservoir (4) par une conduite d'entrée de l'eau et par une conduite de sortie.As illustrated in the figure, the extractor hood for kitchen with thermal energy recovery produced by the hobs, according to this invention, is formed by a hood (1) inside which, according to known means, is installed a heat exchanger (2), made of a suitable material to retain the heat (6) which rises from the stove (7) and transfer it to the water flowing inside the heat exchanger (2). Heat exchanger (2) is connected to a tank (4) by an inlet pipe water and through an outlet pipe.
Sur la conduite d'entrée de l'eau est installée une pompe électrique (3) qui met l'eau en circulation à l'intérieur de l'échangeur de chaleur (2); le fonctionnement de la pompe (3) est réglé par un thermostat (8) disposé à la sortie de l'échangeur de chaleur et étalonné sur une certaine valeur, de manière que l'on puisse obtenir, à la sortie de l'échangeur, de l'eau à la température prédéterminée.On the water inlet pipe is installed a electric pump (3) which circulates the water to the interior of the heat exchanger (2); the pump operation (3) is regulated by a thermostat (8) arranged at the outlet of the heat exchanger heat and calibrated to a certain value, so that can be obtained, at the exit of the exchanger, from water at the predetermined temperature.
L'eau chauffée à la sortie de l'échangeur de chaleur (2) est recueillie dans le réservoir (4) et utilisée par les moyens normaux.Heated water at the outlet of the heat exchanger (2) is collected in the tank (4) and used by normal means.
Le réservoir (4) est muni d'une soupape de sûreté (9) qui s'ouvre à une pression préétablie, et d'un thermomètre (10) qui indique la température de l'eau contenue dans le réservoir.The tank (4) is fitted with a safety valve (9) which opens at a preset pressure, and a thermometer (10) which indicates the water temperature contained in the tank.
Une aide à la circulation de chaleur à l'intérieur de la hotte, et plus particulièrement autour de l'échangeur de chaleur (2) est donnée par l'aspirateur (5), normalement prévu dans toutes les hottes de cuisine, qui lorsqu'il fonctionne, contribue, nous l'avons dit, à ce que la chaleur entoure complètement l'échangeur (2) et qu'il se produise un échange continu, raison pour laquelle l'air qui a cédé sa chaleur est aspiré à l'extérieur et fait place à un nouvel air chaud.An aid to the circulation of heat inside the hood, and more particularly around the heat exchanger (2) is given by the vacuum cleaner (5), normally provided in all fume hoods kitchen, which when it works, contributes, we as said, that the heat completely surrounds the exchanger (2) and that there is an exchange continuous, which is why the air that gave up its heat is drawn outside and gives way to a new hot air.
L'échangeur de chaleur, dans l'exemple illustré, a une forme en serpentin, mais il est évident que l'on peut adopter toutes les formes jugées appropriées, comme, par exemple, des formes qui fassent parcourir par l'eau deux, quatre ou plusieurs fois la longueur de l'échangeur; des formes qui obligeront la chaleur à suivre un parcours en zig-zag entre les tubes, etc. Dans une solution alternative, on peut éliminer la pompe (3) et confier la circulation de l'eau à la seule convection.The heat exchanger, in the example illustrated, has a serpentine shape, but obviously you can adopt all forms deemed appropriate, such as, for example, shapes that make water run through two, four or more times the length of the exchanger; shapes that will force heat to follow a zigzag path between the tubes, etc. In an alternative solution, the pump (3) and entrust the circulation of water to the only convection.
En outre, on peut placer le thermostat et la pompe à l'intérieur de la hotte; il est également possible de réaliser un réservoir à eau superposable à la hotte comme meuble suspendu, ou loger directement le réservoir d'eau à l'intérieur de la hotte.In addition, the thermostat and the pump can be placed inside the hood; it is also possible to make a water tank superimposed on the hood as a hanging piece of furniture, or directly house the water tank inside the hood.
Les avantages obtenus par application du dispositif visé par cette invention sont principalement économiques, dérivant de la récupération de la chaleur produite par les fourneaux et par les casseroles pendant la cuisson, d'où une économie sur le coût de production d'eau chaude; quant aux avantages écologiques, ils dérivent de la réduction de la pollution, grâce à la production d'eau chaude sans autre emploi d'énergie.The advantages obtained by applying the device targeted by this invention are mainly economical, derived from heat recovery produced by stoves and pans during cooking, saving on the cost of hot water production; as to the benefits ecological they derive from the reduction of pollution, thanks to the production of hot water without other use of energy.
Un autre avantage réside dans la diminution de l'usure, et donc dans la durée de vie prolongée du ventilateur d'aspiration de la hotte, qui n'est plus exposé à des températures très élevées.Another advantage lies in the reduction of wear, and therefore in the extended life of the fan the hood, which is no longer exposed to very high temperatures.
Un autre avantage encore est l'émission de fumées à basse température qui ne contribuent pas à accroítre la chaleur dans l'atmosphère.Yet another advantage is the emission of fumes to low temperature which do not contribute to increase the heat in the atmosphere.
