Description

La présente invention concerne un dispositif accélérateur de fluide, notamment pour circuit de chauffage central à eau.The present invention relates to a fluid accelerator device, in particular for a central water heating circuit.

Depuis la sensibilisation du public aux problèmes posés par l'approvisionnement en énergie, de nombreux systèmes "récupérateurs de calories" sont apparus sur le marché, notamment des grilles et/ou des chenêts destinés à être placés dans des cheminées à feu ouvert, et réalisés au moyen de tubes creux, raccordés à un circuit conventionnel de chauffage à circulation d' eau. La partie du circuit dans laquelle est connecté le récupérateur, comporte habituellement un dispositif appelé circulateur, assurant la mise en circulation du fluide dans les conduits, afin d'éviter une surchauffe locale susceptible de provoquer une surpression qui risque d'endommager les tubulures.Since raising public awareness of the problems posed by energy supply, many "calorie recovery" systems have appeared on the market, in particular grates and / or chenets intended to be placed in open fireplaces, and produced by means of hollow tubes, connected to a conventional water circulation heating circuit. The part of the circuit in which the recuperator is connected, usually includes a device called a circulator, ensuring the circulation of the fluid in the conduits, in order to avoid local overheating liable to cause an overpressure which risks damaging the pipes.

Les circulateurs connus sont entraînés par un moteur électrique. De ce fait, le problème d'une éventuelle surchauffe locale devient particulièrement crucial en cas de panne d'électricité.Known circulators are driven by an electric motor. As a result, the problem of possible local overheating becomes particularly crucial in the event of a power failure.

On a déjà proposé divers systèmes répondant aux soucis d'assurer la circulation d'eau dans uns installation de chauffage central en cas de panne d' électricité. En particulier, on connaît un système basé sur le principe de la batterie rechargeable, qui fournit l'énergie électrique nécessaire à entraîner l'accélérateur en cas de coupure du courant. Un tel dispositif a une autonomie extrêmement limitée. Il Este peu fiable du fait que sa mise en fonction n'est pas automatique. En outre, sa mise en oeuvre est relativement coûteuse.Various systems have already been proposed which meet the concerns of ensuring the circulation of water in a central heating installation in the event of a power failure. In particular, a system is known based on the principle of the rechargeable battery, which provides the electrical energy necessary to drive the accelerator in the event of a power cut. Such a device has an extremely limited autonomy. It is unreliable because its activation is not automatic. In addition, its implementation is relatively expensive.

Pour pallier ces différents inconvénients, il est pratiquement obligatoire d'installer un thermosiphon dans tout système de chauffage alimenté par une chaudière à bois ou à charbon. Dans le cas d'un récupérateur de calories installé dans une cheminée à feu ouvert, le montage en thermosiphon est très souvent impossible. Le récupérateur se trouve en général à la même hauteur que les radiateurs, de sorte qu'une installation en thermosiphon n'est guère possible.To overcome these various drawbacks, it is practically compulsory to install a thermosyphon in any heating system supplied by a wood or coal boiler. In the case of a heat recovery unit installed in an open fire, mounting in a thermosiphon is very often impossible. The recuperator is generally at the same height as the radiators, so that a thermosyphon installation is hardly possible.

La présente invention se propose de pallier les différents inconvénients susmentionnés et se propose d'assurer le fonctionnement permanent d'un accélérateur dont l'autonomie est illimitée, l'encombrement réduit et le coût relativement modeste. La conception simple du dispositif proposé permet de garantir une fiabilité quasiment totale et un entretien nul.The present invention proposes to overcome the various drawbacks mentioned above and proposes to ensure the permanent operation of an accelerator whose autonomy is unlimited, the reduced size and the relatively modest cost. The simple design of the proposed device guarantees almost total reliability and zero maintenance.

Dans ce but, le dispositif accélérateur tel que susmentionné, est caractérisé en ce qu'il comporte un organe accélérateur monté dans le circuit, un moteur électrique couplé audit organe accélérateur, une turbine d'entraînement également couplée audit organe accélérateur, et des moyens pour enclencher automatiquement la turbine d'entraînement en cas d'arrêt de l'alimentation du moteur électrique.For this purpose, the accelerator device as mentioned above, is characterized in that it comprises an accelerator member mounted in the circuit, an electric motor coupled to said accelerator member, a drive turbine also coupled to said accelerator member, and means for Automatically switch on the drive turbine if the power supply to the electric motor stops.

Selon une forme de réalisation préférée, le dispositif est caractérisé en ce que lesdits moyens pour enclencher automatiquement la turbine d'entraînement comprennent une vanne électromagnétique, agencée pour alimenter en fluide sous pression un injecteur destiné à engendrer la rotation de la turbine, dès que le courant électrique d'alimentation du moteur est coupé.According to a preferred embodiment, the device is characterized in that said means for automatically engaging the drive turbine comprise an electromagnetic valve, arranged to supply fluid under pressure to an injector intended to generate the rotation of the turbine, as soon as the electric power supply to the motor is cut off.

L'organe accélérateur est avantageusement monté sur un axe unique entraîné soit par le moteur électrique, soit par la turbine. La source de fluide sous pression qui alimente la turbine est de préférence indépendante du circuit de chauffage central, ce qui permet d'augmenter la fiabilité du dispositif.The accelerator member is advantageously mounted on a single axis driven either by the electric motor or by the turbine. The source of pressurized fluid which feeds the turbine is preferably independent of the central heating circuit, which increases the reliability of the device.

La vanne électromagnétique est agencée pour que l'alimentation de la turbine soit automatiquement fermée lorsque le moteur électrique est alimenté en courant électrique. De ce fait, le dispositif est en quelque sorte programmé pour sélectionner automatiquement le mode d'entraînement de l'accélérateur en fonction de conditions extérieures non prévisibles.The electromagnetic valve is arranged so that the power supply to the turbine is automatically closed when the electric motor is supplied with electric current. As a result, the device is somehow programmed to automatically select the accelerator drive mode based on unpredictable external conditions.

L'organe accélérateur peut être constitué par une turbine rotative montée dans un boîtier étanche intégré au circuit de chauffage, ou par une pompe, notamment une pompe rotative.The accelerator member can be constituted by a rotary turbine mounted in a sealed housing integrated into the heating circuit, or by a pump, in particular a rotary pump.

La présente invention sera mieux comprise en référence à la description d'un exemple de réalisation préféré et des dessins annexés dans lesquels :The present invention will be better understood with reference to the description of a preferred embodiment and the accompanying drawings in which:

la figure 1 représente une vue schématique de la turbine servant d'entrai- nement d'appoint, etFIG. 1 represents a schematic view of the turbine serving as a drive extra support, and

la figure 2 représente une vue en coupe transversale selon la ligne a-a de la figure 1.FIG. 2 represents a cross-sectional view along line a-a of FIG. 1.

En référence aux figures, la turbine 1, montée dans un boîtier 10,est destinée à être entraînée en rotation autour de son axe central 6 lorsqu'un jet d' eau sous pression 5 est projeté sur ses pales par l'injecteur 2. Une vanne électro-magnétique 4 ouvre ou ferme le circuit reliant le conduit d'eau 5 à l'injecteur 2. Le boîtier 10 de la turbine est solidaire de la carcasse d'un moteur électrique 7,dont l'axe 6 est connecté à la fois à la turbine 1 et à l'accélérateur 8, ces deux organes étant disposés de part et d'autre de la carcasse 7 du moteur.With reference to the figures, the turbine 1, mounted in a housing 10, is intended to be driven in rotation about its central axis 6 when a jet of pressurized water 5 is projected onto its blades by the injector 2. A electromagnetic valve 4 opens or closes the circuit connecting the water pipe 5 to the injector 2. The housing 10 of the turbine is secured to the carcass of an electric motor 7, the axis 6 of which is connected to the both to the turbine 1 and to the accelerator 8, these two members being arranged on either side of the carcass 7 of the engine.

En fonctionnement normal, le moteur électrique 7 alimenté en courant en- est traîne l'accélérateur 8 qui en charge, puisqu'il est monté sur un circuit conventionnel 9 de chauffage central, ou sur la partie du circuit dans lequel est incorporé un récupérateur de calories placé dans une cheminée à feu ouvert. Le moteur électrique entraîne également la turbine 1 qui tourne à vide.In normal operation, the electric motor 7, supplied with current, drags the accelerator 8 which charges it, since it is mounted on a conventional central heating circuit 9, or on the part of the circuit in which a heat recovery unit is incorporated. calories placed in an open fire. The electric motor also drives the turbine 1 which rotates when empty.

En cas de rupture de l'alimentation en courant électrique du moteur 7, la vanne électromagnétique 4, pré-armée au moyen d'un ressort (non représenté), ouvre l'aliméntation en eau 5 de l'injecteur 2, et engendre la rotation de la turbine 1, qui prend le relais du moteur électrique. 7 pour faire tourner l'accélérateur 8. L'eau projetée par l'injecteur 2 sur les pales de la turbine 1 est évacuée par le conduit 3.In the event of a break in the electric current supply to the motor 7, the electromagnetic valve 4, pre-armed by means of a spring (not shown), opens the water supply 5 of the injector 2, and generates the rotation of turbine 1, which takes over from the electric motor. 7 to rotate the accelerator 8. The water projected by the injector 2 on the blades of the turbine 1 is discharged through the conduit 3.

En conséquence, grâce au dispositif décrit, l'entraînement de l'accélérateur est assuré soit par un moteur électrique 7, soit par la turbine 1, et le passage du premier au second mode d'entraînement se fait automatiquement en cas de coupure, même accidentelle, de l'alimentation en courant électrique du moteur 7.Consequently, thanks to the device described, the accelerator is driven either by an electric motor 7 or by the turbine 1, and the transition from the first to the second drive mode takes place automatically in the event of a cut, even accidental supply of electric power to the motor 7.
