Description

L'invention se rapporte à un extracteur mécanique des gaz par un conduit refoulant à l'air libre tel un conduit de ventiletion d'un volume ou un conduit d'évacuation de fumées. The invention relates to a mechanical gas extractor by a conduit discharging into the open air such as a volume ventilation duct or a smoke evacuation duct.

Les hahitations, et à fortiori les résidences secondaires fermées plusieurs mois par an sont généralement trop chaudes l'été et trop humides l'hiver et ce du fait d'un manque de ventilation permanente. The hahitations, and a fortiori the second residences closed several months a year are generally too hot the summer and too humid the winter and this because of a lack of permanent ventilation.

Quant aux appareils à combustion tels les cheminées a feu de bois, leur conduit est généralement de hauteur insuffisante pour assurer un tirage naturel. As for combustion appliances such as wood fireplaces, their flue is generally of insufficient height to ensure a natural draft.

Afin d'y remédier, il est connu d'installer des extracteurs mécaniques comprenant des turbines actionnées par un moteur électrique. In order to remedy this, it is known to install mechanical extractors comprising turbines actuated by an electric motor.

Outre que dans les résidences secondaires, pendant de longues périodes, le courant électrique est généralement coupé et ne peut donc alimenter le moteur, le fonctionnement de celui-ci entraîne quoi qu'il en soit une consommation d'énergie d'un coût non négligeable. In addition to the fact that in second homes, for long periods, the electric current is generally cut and therefore cannot supply the engine, the functioning of this one leads in any case to an energy consumption of a significant cost. .

Un résuital que l'invention vise à obtenir est un extracteur mécanique qui, sans consommation d'énergie faeturable assure une extraction des gaz de l'enceinte raccordée au conduit qui le porte, tel un vide ventilé ou un appareil à combustion. A resuital that the invention aims to obtain is a mechanical extractor which, without consuming feturable energy ensures extraction of the gases from the enclosure connected to the duct which carries it, such as a ventilated vacuum or a combustion appliance.

A cet effet, elle a pour objet un extracteur du type cité plus haut notamment caractérisé en ce que d'une part sont, prévus des moyur.'s rie nuidaqe en rotation d'une turbine exposée au vent et dont jes ailettes sont inclinées de manière à imposer un sens de rotation à ladite turbine et d'autre part en ce que, à cette turbine, est liée en rotation une vis d'Archimbde logée dans le conduit et dont le sens du pas de l'hélice est tel que compte tenu du sens de rotation imposé à la turbine, la rotation de la vis assure l'extraction des gaz de l'enceinte raccordée au conduit. To this end, it relates to an extractor of the type mentioned above, in particular characterized in that, on the one hand, there are provided hubs for rotating a turbine exposed to the wind and whose fins are inclined by so as to impose a direction of rotation on said turbine and on the other hand in that, to this turbine, is linked in rotation an Archimbus screw housed in the duct and whose direction of the pitch of the propeller is such as counts given the direction of rotation imposed on the turbine, the rotation of the screw extracts the gases from the enclosure connected to the duct.

L'invention sera mieux comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente :
Figure 1, l'extracteur, vue en coupe axiale,
Figure 2, une coupe selon Il-Il de la figure 1.The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the appended drawing which represents:
Figure 1, the extractor, viewed in axial section,
Figure 2, a section along Il-Il of Figure 1.

tn se reportant au dessin, on voit que le conduit (I) débouche - à sa basé, dans une enceinte (3) telle un vide ventilé, ou un appareil à combustion à foyer ouvert ou fermé et, - à sa partie supérieure (4), à l'air libre. tn referring to the drawing, we see that the duct (I) opens - at its base, in an enclosure (3) such as a ventilated vacuum, or a combustion appliance with open or closed hearth and, - at its upper part (4 ), outdoors.

Par des supports (5) , un chapeau (6) est fixé à une certaine distance "d" au dessus de ce conduit (1), et ce notamment pour éviter l'entrée des eaux pluviales. By supports (5), a cap (6) is fixed at a certain distance "d" above this conduit (1), and this in particular to avoid the entry of rainwater.

Selon une caractéristique de l'invention --d'une part, sont prévus des moyens (7, 8) de guidage en rotation d'une turbine (9) exposée au vent dont les ailettes (10) sont inclinées de manière à imposer un sens de rotation à la turbine (9j occupant une partie de la distance et entre le dessus du conduit et le chapeau et, - d'autre part, à cette turbine est liée en rotation- une vis d'Archimbde (11) logée dans le conduit (1) et dont le sens du pas de l'hélice (12) est tel que compte tenu du sens de rotation imposé à la turbine, par sa rotation la vis assure l'extraction des gaz de l'enceinte (3) raccordée au conduit. According to a characteristic of the invention - on the one hand, means (7, 8) are provided for guiding in rotation a turbine (9) exposed to the wind, the fins (10) of which are inclined so as to impose a direction of rotation to the turbine (9j occupying part of the distance and between the top of the duct and the bonnet and, - on the other hand, to this turbine is linked in rotation- an Archimbus screw (11) housed in the conduit (1) and the direction of the pitch of the propeller (12) of which is such that, taking into account the direction of rotation imposed on the turbine, by its rotation the screw ensures the extraction of gases from the enclosure (3) connected to the conduit.

De préférence, la turbine (9) est portée par un arbre creux (13) s' ajustant dans le conduit (1) dans lequel il est libre en rotation tandis que la vis d'Archimède (12) qui a un diamètre extérieur égal au diamètre intérieur de cet arbre creux est en son centre solidaire d'un arbre (14)- guidé- en rotation dans les paliers (7, 8) précités. Preferably, the turbine (9) is carried by a hollow shaft (13) s' adjusting in the conduit (1) in which it is free to rotate while the Archimedes screw (12) which has an outer diameter equal to inner diameter of this hollow shaft is in its center integral with a shaft (14) - guided- in rotation in the bearings (7, 8) above.

Entre la base (2) du conduit (1) et l'enceinte (3-), peut avantageusement être posée une grille (15) empêchant l'entrée de corps étrangers et notamment d'insectes. Les paliers (7, 8) seront avantageusement pourvus de roulements par exemple à billes. Between the base (2) of the conduit (1) and the enclosure (3-), can advantageously be placed a grid (15) preventing the entry of foreign bodies and in particular insects. The bearings (7, 8) are advantageously provided with bearings, for example ball bearings.

Le conduit (1) et ou les supports (5) du chapeau seront de préférence portés directement ou in-directement par la construction par l'intermédiaire de moyens (16, 17) amortissant les vibrations. The duct (1) and or the supports (5) of the cap will preferably be carried directly or indirectly by the construction by means of means (16, 17) damping the vibrations.

Bien entendu, cet extracteur est surtout destiné à être placé en toiture sous l'action du vent, pour assurer un tirage, une ventilation continue par extraction de l'air. Of course, this extractor is especially intended to be placed on the roof under the action of the wind, to ensure draft, continuous ventilation by extracting air.

La turbine à ailettes qui tourne toujours dans le meme sens et au moindre vent entraîne dans sa- rotation la vis d'Archimède qui remonte l'air créant une dépression ascensionnelle assurant ainsi un bon tirage ou une ventilation permanente du local. The finned turbine which always turns in the same direction and at the slightest wind drives in its rotation the Archimedes screw which rises the air creating an upward depression thus ensuring a good draft or permanent ventilation of the room.

L'appareil peut être conçu en toute matière telle le chlorure de polyvinyle ou l'aluminium anodisé et présenter un ton adapté à l'environnement. The device can be designed in any material such as polyvinyl chloride or anodized aluminum and present a tone adapted to the environment.

Le chapeau est évidemment soigneusement étudié pour que l'extracteur soit parfaitement étanche aux pluies battantes. The hat is obviously carefully studied so that the extractor is perfectly sealed against heavy rain.

I1 est tien entendu recommandé pour les maisons secondaires et les bunqalow des villages d-e vacances qui, plusieurs mois par an, sont fermés et sans cour an t électrique, dans lesquels puisque l'extracteur tourne sous l'effet seul du vent, il permet donc une ventilation permanente de l'habitation et la disparition du phénomène dû à l'humidité stagnante. I1 faut bien entendu pour cela disposer au préalable d'entrée d'air en nombre suffisant. It is of course recommended for secondary houses and bunqalows in holiday villages which, for several months a year, are closed and have no electric current, in which since the extractor turns under the sole effect of the wind, it therefore allows permanent ventilation of the house and the disappearance of the phenomenon due to stagnant humidity. It is of course necessary for this to have sufficient air intake beforehand.

Dans le cas d'une utilisation sur, des cheminées d'évacuation des fumées, on notera que par sa conception, l'extacteur ne modifie pas de manière sensible la section de-la cheminée et de ce fait en cas de vent nul ou presque nul, le tirage naturel n'est pas affecté. In the case of use on, smoke evacuation chimneys, it will be noted that by its design, the extractor does not appreciably modify the section of the chimney and therefore in the event of zero or almost wind null, the natural draw is not affected.

Dans une variante de réalisation, l'extracteur est pourvu d'un dispositif d'arrêt manoeuvrable de l'intérieur du local.  In an alternative embodiment, the extractor is provided with a maneuverable stop device from inside the room.
