On connaît divers types de chaudières qui comportent généralement un réservoir de stockage du liquide caloporteur et un thermo-plongeur agencé pour assurer le chauffage de ce liquide. Ces chaudières contiennent souvent un volume d'eau relativement important et ont de ce fait une inertie thermique élevée. En outre, leur encombrement est tel qu'elles ne peuvent pas être montées facilement dans un appartement de petites dimensions et ne peuvent pas être utilisées comme appareils de chauffage individuel. voir, par example, GB-A-2 092 282.Various types of boilers are known, which generally include a storage tank for the heat-transfer liquid and a heat sink designed to heat this liquid. These boilers often contain a relatively large volume of water and therefore have a high thermal inertia. In addition, their size is such that they cannot be easily mounted in a small apartment and cannot be used as individual heaters. see, for example, GB-A-2,092,282.

La présente invention se propose de pallier à ces inconvénients en réalisant une chaudière de très petites dimensions, qui se prête bien à une utilisation en tant qu'appareil de chauffage individuel pouvant être monté dans un petit appartement et notamment dans les éléments de meubles d'une cuisine.The present invention proposes to overcome these drawbacks by providing a boiler of very small dimensions, which lends itself well to use as an individual heating device which can be mounted in a small apartment and in particular in furniture elements. a kitchen.

Ce but est atteint par la chaudière selon l'invention caractérisée en ce que les orifices d'arrivée et de sortie sont respectivement couplés à une tubulure d'amenée et à une tubulure d'évacuation qui sont disposées tangentiellement par rapport au réservoir cylindrique, et en ce que ladite tubulure d'amenée est voisine du fond du réservoir et ladite tubulure d'évacuation est voisine du haut du réservoir, de telle manière qu'il se forme à l'intérieur dudit réservoir une turbulence cylindrique orientée de bas en haut.This object is achieved by the boiler according to the invention characterized in that the inlet and outlet orifices are respectively coupled to a supply pipe and to a discharge pipe which are arranged tangentially with respect to the cylindrical tank, and in that said supply pipe is close to the bottom of the tank and said discharge pipe is close to the top of the tank, in such a way that a cylindrical turbulence oriented from bottom to top is formed inside said tank.

Selon un mode de réalisation avantageuse, la chaudière est caractérisée en ce que le réservoir comporte plusieurs entrées dont chacune est connectée à une tubulure d'amenée tangentielle par rapport aux parois intérieures du réservoir.According to an advantageous embodiment, the boiler is characterized in that the tank has several inlets, each of which is connected to a supply pipe tangential to the walls inside the tank.

Ce réservoir peut également comporter plusieurs sorties dont chacune est connectée à une tubulure d'évacuation tangentielle par rapport aux parois intérieures du réservoir.This tank can also have several outlets, each of which is connected to a tangential discharge pipe with respect to the interior walls of the tank.

Selon une forme de réalisation préférée, la tubulure d'amenée forme un angle aigu avec une droite parallèle à l'axe du réservoir. Dans ce cas, l'angle est avantageusement compris entre 0 et 80°.According to a preferred embodiment, the supply tube forms an acute angle with a straight line parallel to the axis of the reservoir. In this case, the angle is advantageously between 0 and 80 °.

De façon préférentielle, la chaudière comporte plusieurs réservoirs montés en batterie.Preferably, the boiler comprises several tanks mounted in battery.

Selon un autre mode de réalisation, ces réservoirs peuvent être montés en série.According to another embodiment, these tanks can be mounted in series.

Selon un autre mode de réalisation avantageuse, ces réservoirs sont montés en parallèle.According to another advantageous embodiment, these tanks are mounted in parallel.

Selon une forme de réalisation préférée, chaque réservoir contient une batterie de corps de chauffe allongés disposés de façon centrale dans le volume de liquide contenu dans ce réservoir.According to a preferred embodiment, each tank contains a battery of elongated heating bodies arranged centrally in the volume of liquid contained in this tank.

De façon préférentielle, la chaudière peut comporter quatre réservoirs disposés symétriquement selon les côtés d'un carré et les tubulures d'amenée d'une part et les tubulures d'évacuation d'autre part sont respectivement connectées en deux points du circuit d'utilisation.Preferably, the boiler can comprise four tanks arranged symmetrically along the sides of a square and the supply pipes on the one hand and the discharge pipes on the other hand are respectively connected at two points of the circuit of use .

Selon une forme de réalisation préférée, les tubulures tangentielles sont réparties de façon régulière autour des parois du réservoir.According to a preferred embodiment, the tangential tubes are distributed regularly around the walls of the tank.

  • la figure 5 représente une vue de dessus de la réalisation selon la figure 4.
The present invention will be better understood with reference to the description of an exemplary embodiment and the attached drawing in which:
  • FIG. 1 represents a perspective view of a first embodiment of an electric boiler according to the invention,
  • FIG. 2 represents a perspective view illustrating a preferred embodiment of the electric boiler according to the invention,

  • FIG. 4 represents an elevation view of another construction of the electric boiler according to the invention, and
  • FIG. 5 represents a top view of the embodiment according to FIG. 4.

En référence à la figure 1, la chaudière électrique 10 représentée comporte essentiellement un réservoir cylindrique vertical 11 contenant un liquide caloporteur et au moins un corps de chauffe 12 plongé dans ce liquide. Selon la réalisation représentée, le corps de chauffe se compose de trois thermo-plongeurs 13 qui sont montés à la base d'un élément de fermeture 14 fixé à l'extrémité supérieure du réservoir 11 pour assurer une fermeture étanche de ce réservoir. Dans le présent cas, le dispositif de fermeture 14 comporte un socle inférieur 15 fileté, destiné à être vissé dans le col du réservoir 11, équipé d'un filetage 16 complémentaire.Referring to Figure 1, the electric boiler 10 shown essentially comprises a vertical cylindrical tank 11 containing a heat transfer liquid and at least one heating body 12 immersed in this liquid. According to the embodiment shown, the heating body consists of three immersion heaters 13 which are mounted at the base of a closure element 14 fixed to the upper end of the reservoir 11 to ensure a sealed closure of this reservoir. In the present case, the closure device 14 comprises a lower base 15 threaded, intended to be screwed into the neck of the reservoir 11, equipped with a complementary thread 16.

Pour permettre la circulation du liquide caloporteur à l'intérieur du réservoir 10, ce dernier est équipé d'une tubulure d'amenée 17 voisine du fond du réservoir et d'une tubulure d'évacuation 18 voisine du haut de ce réservoir. La tubulure d'amenée 17 définit l'entrée dans le réservoir 11 et la tubulure d'évacuation 18 définit la sortie de ce réservoir. On notera que l'entrée et la sortie sont tangentielles et orientées de telle manière que la circulation à l'intérieur du réservoir s'effectue sous la forme d'une turbulence cylindrique orientée de bas en haut. Dans ce but, l'axe 19 de la tubulure d'amenée 17 forme avec une verticale 20, un angles α qui est de préférence compris entre 0 et 80° et avantageusement voisin de 60°. L'axe de la tubulure d'évacuation 18 peut former un angle droit avec la verticale.To allow the circulation of the heat transfer liquid inside the tank 10, the latter is equipped with a supply pipe 17 close to the bottom of the tank and a discharge pipe 18 close to the top of this tank. The inlet pipe 17 defines the inlet to the tank 11 and the outlet pipe 18 defines the outlet from this tank. It will be noted that the inlet and the outlet are tangential and oriented in such a way that the circulation inside the tank takes place in the form of a cylindrical turbulence oriented from bottom to top. For this purpose, the axis 19 of the supply pipe 17 forms with a vertical 20, an angle α which is preferably between 0 and 80 ° and advantageously close to 60 °. The axis of the discharge pipe 18 can form a right angle with the vertical.

Dans cette forme de réalisation, la chaudière électrique comporte un seul réservoir cylindrique dans lequel sont logés les corps de chauffe nécessaires pour assurer l'apport en énergie électrique suffisante pour. engendrer un réchauffement rapide et efficace du liquide caloporteur contenu dans ce réservoir.In this embodiment, the electric boiler comprises a single cylindrical tank in which are housed the heating bodies necessary to ensure the supply of sufficient electric energy for. cause rapid and effective heating of the heat transfer liquid contained in this tank.

La réalisation selon la figure 2 et qui constitue la forme préférentielle de la chaudière électrique selon l'invention, comporte quatre réservoirs 11 contenant chacun un liquide caloporteur et destiné à recevoir chacun au moins un thermo-plongeur pour assurer le réchauffement du liquide caloporteur. Chacun de ces réservoirs comporte une tubulure d'amenée 17 et une tubulure d'évacuation 18 qui sont de préférence agencées de manière à permettre une pénétration sensiblement tangentielle du liquide caloporteur dans le réservoir et une évacuation également tangentielle de ce liquide hors du réservoir. Les quatre réservoirs 11 sont couplés entre eux par l'intermédiaire d'une part de leur tubulure d'amenée 17 et d'autre part par leur tubulure d'évacuation 18. Toutes les tubulures d'amenée 17 sont connectées à un conduit d'amenée 21 et toutes les tubulures d'évacuation sont connectées à un conduit de sortie 22. Ces deux conduits sont raccordés à un réseau d'utilisation comportant de préférence un certain nombre d'échangeurs de chaleur constitués par des radiateurs de chauffage. Comme précédemment, les tubulures d'amenée sont disposées de telle manière que la circulation à l'intérieur des réservoirs se fasse selon une trajectoire sensiblement hélicoïdale allant de la tubulure d'amenée à la tubulure d'évacuation.The embodiment according to Figure 2 and which is the preferred form of the electric boiler according to the invention, comprises four tanks 11 each containing a heat transfer liquid and intended to each receive at least one immersion heater to ensure the heating of the heat transfer liquid. Each of these reservoirs comprises a supply pipe 17 and a discharge pipe 18 which are preferably arranged so as to allow a substantially tangential penetration of the heat transfer liquid into the tank and also a tangential discharge of this liquid from the tank. The four reservoirs 11 are coupled together via one hand of their supply pipe 17 and secondly by their discharge pipe 18. All the supply pipes 17 are connected to a conduit inlet 21 and all the evacuation pipes are connected to an outlet duct 22. These two ducts are connected to a usage network preferably comprising a certain number of heat exchangers constituted by heating radiators. As before, the supply pipes are arranged in such a way that the circulation inside the tanks takes place along a substantially helical trajectory going from the supply pipe to the discharge pipe.

Comme le montre plus particulièrement la figure 3, les différents réservoirs 11 sont disposés en étoile et raccordés au conduit de sortie 22 par les tubulures d'évacuation 18.As shown more particularly in FIG. 3, the various reservoirs 11 are arranged in a star and connected to the outlet conduit 22 by the evacuation pipes 18.

Les figures 4 et 5 illustrent une variante selon laquelle le réservoir 11 comporte plusieurs tubulures d'amenée et au moins une tubulure d'évacuation. Les tubulures d'amenée 30 sont disposées de telle manière qu'elles débouchent à l'intérieur du réservoir en des points décalés angulairement de 120°. En outre ces tubulures d'amenée sont disposées sensiblement tangentiellement par rapport à la paroi intérieure du réservoir 11 et enfin leur axe forme un angles α qui est compris entre 0 et 80° et de préférence voisin de 60° par rapport à la verticale. Cet agencement permet de créer à l'intérieur du réservoir une circulation hélicoïdale illustrée schématiquement par les flèches 31. Cette circulation hélicoïdale a pour principal avantage d'améliorer le passage du liquide caloporteur sur les thermo-plongeurs et d'accroître de ce fait le rendement de la chaudière en réduisant considérablement le temps nécessaire pour porter le liquide caloporteur à la température souhaitée.Figures 4 and 5 illustrate a variant according to which the reservoir 11 comprises several supply pipes and at least one discharge pipe. The inlet pipes 30 are arranged in such a way that they open out inside the tank at points angularly offset by 120 °. In addition, these supply pipes are arranged substantially tangentially with respect to the inner wall of the tank 11 and finally their axis forms an angle α which is between 0 and 80 ° and preferably around 60 ° relative to the vertical. This arrangement makes it possible to create inside the tank a helical circulation illustrated schematically by the arrows 31. This helical circulation has the main advantage of improving the passage of the heat transfer liquid over the immersion heaters and thereby increasing the yield of the boiler by considerably reducing the time required to bring the heat transfer liquid to the desired temperature.

La tubulure d'évacuation 32 peut être disposée dans un plan horizontal. Elle est de préférence montée tangentiellement par rapport aux parois du réservoir. Elle peut être dédoublée voire triplée. Toutefois, on notera que l'obtention d'une turbulence hélicoïdale à l'intérieur du réservoir est essentiellement due à la disposition géométrique des tubulures d'amenée qui jouent le rôle d'injecteurs.The discharge pipe 32 can be arranged in a horizontal plane. It is preferably mounted tangentially with respect to the walls of the tank. It can be split or even tripled. However, it will be noted that obtaining a helical turbulence inside the tank is essentially due to the geometric arrangement of the intake pipes which act as injectors.

Au point de vue électrique, les différents thermo-plongeurs sont alimentés en puissance à travers un circuit commandé soit par un dispositif programmable soit par des thermostats ou par d'autres capteurs de température. Ces différents corps de chauffe peuvent être commandés individuellement ou en combinaison selon les besoins. Le liquide caloporteur est propulsé par une pompe montée sur le circuit (non représentée) à l'intérieur du ou des réservoirs de la chaudière. Lorsque cette chaudière se compose de plusieurs réservoirs comme le montrent les figures 2 et 3, les différentes tubulures d'amenée constituent un répartiteur qui permet d'amener un même débit de fluide dans les différents réservoirs. La circulation hélicoïdale à l'intérieur du réservoir assure le meilleur échange thermique possible entre les thermo-plongeurs et le liquide caloporteur. Elle permet notamment de brasser le liquide et d'éviter le dépôt de bulles de gaz sur les thermo-plongeurs en formant ainsi une sorte de gaine isolante séparant les éléments chauffants du liquide caloporteur. L'effet obtenu est que la montée en température est extrêmement rapide avec des puissances électriques relativement modestes.From an electrical point of view, the various immersion heaters are supplied with power through a circuit controlled either by a programmable device or by thermostats or by other temperature sensors. These different heaters can be ordered individually or in combination as required. The heat transfer liquid is propelled by a pump mounted on the circuit (not shown) inside the tank (s) of the boiler. When this boiler is made up of several tanks as shown in FIGS. 2 and 3, the different supply pipes constitute a distributor which allows the same flow of fluid to be brought into the different tanks. The helical circulation inside the tank ensures the best possible heat exchange between the immersion heaters and the heat transfer liquid. It makes it possible in particular to stir the liquid and to avoid the deposit of gas bubbles on the immersion heaters, thus forming a kind of insulating sheath separating the heating elements from the heat transfer liquid. The effect obtained is that the temperature rise is extremely rapid with relatively modest electrical powers.

Les différents réservoirs peuvent être disposés en ligne au lieu d'être disposés en étoile. Il est possible de les connecter en série ou de les connecter en parallèle.The different tanks can be arranged in line instead of being arranged in a star. It is possible to connect them in series or to connect them in parallel.
