L'INDICATION DU DOMAINE TECHNIQUE
L'invention faisant l'objet de la pressente demande relève du domaine de l'appareillage électro-domestique et est destinée à remplacer le souf flet manuel pour toutes cheminées ou barbecues.INDICATION OF THE TECHNICAL AREA
The invention which is the subject of the present application is in the field of household electrical appliances and is intended to replace the manual bellows fan for all fireplaces or barbecues.
EXPOSE DE L'INVENTION
Le SOUFFLET AUTOMATIQUE ELECTRONIQUE " se compose de deux parties un mécanisme assurant le fonctionnement automatique et une enveloppe extérieure.STATEMENT OF THE INVENTION
The ELECTRONIC AUTOMATIC BELLOWS "consists of two parts, a mechanism ensuring automatic operation and an external envelope.
LE MECANISE se compose lui-meme de trois groupes d'appas reils : - L'alimentation
- La commande de régulation
- La ventilation
L'alimentation : Elle est assurée à partir du secteur par un transformateur monophasé 220 b 6,3 V.LE MECANISE itself is made up of three groups of devices: - Food
- The regulation command
- Ventilation
Power supply: It is supplied from the mains by a single phase transformer 220 b 6.3 V.
Un pont de diodes raccordé au secondaire du transformateur redresse le courant de sortie. L'interrupteur Marche / Arrêt ntagit que sur le circuit 6,3 V redressé. A diode bridge connected to the transformer secondary rectifies the output current. The on / off switch only works on the rectified 6.3 V circuit.
La commande de régulation : Elle s'effectue de deux manières distinctes manuellement; en agissant sur la position du potentiomètre de 220 ka selon le régime du moteur désiré. The regulation command: It is carried out in two distinct ways manually; by acting on the position of the potentiometer of 220 ka according to the desired engine speed.
Automatiquement; par l'intermédiaire de la photo-résistance.Automatically; through photo-resistance.
Ces deux organes polarisent conjointement la base du transistor T1 puis celle de T 2 mcnté en émetteur commun. These two bodies jointly polarize the base of the transistor T1 then that of T 2 mcnté in common emitter.
La ventilation : Elle est assurée par l'hélice qu'anime le moteur électrique de 6V - 1W, excité par le courant collecteur de T2. Ventilation: It is provided by the propeller driven by the 6V - 1W electric motor, excited by the collector current of T2.
Le seul réglage nécessaire à l'appareil s'éffectue en agissant sur le potentiomètre, suivant l'incandescence désirée. La photo-résistance prend ensuite le relais et excite le moteur dès que la luminosité du foyer tom- be en dessous du point de consigne choisi par l'utilisateur.The only adjustment necessary for the device is made by acting on the potentiometer, according to the desired glow. The photoresistor then takes over and energizes the motor as soon as the brightness of the fireplace falls below the set point chosen by the user.
a consommation de l'ensemble du système se situant autour de 1 à 2 Wh autorise l'utilisation des piles sèches du commerce ou de tout autre générateur de faible puissance. A consumption of the whole system being around 1 to 2 Wh authorizes the use of dry commercial batteries or any other low power generator.
L'ENVELOPPE EXTERIEPTRE. L'appareil est composé à la base, d'un cylindre creux de 5Omm de diamètre et de 30mm de hauteur, surmonté d'un cane excentré de même diamètre et de 40mm de hauteur. Ce dernier se prolonge et s'appuie sur un cylindre creux de 20mm de diamètre terminé par un coude de 65 degrés environ. ( L'angle choisi permet une attaque des flammes à la base . )
flans ce coude vient se loger le moteur sur l'axe duquel est calée l'hé- lice. Les conducteurs d'alimentation de ce moteur rejoignent par l'intérieur du corps de l'appareil les systèmes de commandes accessibles extérieurement.THE OUTER ENVELOPE. The device is composed at the base, of a hollow cylinder of 50mm in diameter and 30mm in height, surmounted by an eccentric cane of the same diameter and 40mm in height. The latter extends and rests on a hollow cylinder 20mm in diameter ending in an elbow of about 65 degrees. (The angle chosen allows an attack of the flames at the base.)
blanks this elbow houses the motor on the axis of which the propeller is fixed. The supply conductors of this motor join the control systems accessible from the outside through the body of the device.

REALISATION
Nous avons réalisé le " SOUFFLET AUTOMATIQUE ELECTRONIQUE" en chlorure de polyvinyle de 2,5mm d'épaisseur.PRODUCTION
We produced the "AUTOMATIC ELECTRONIC BELLOWS" in 2.5mm thick polyvinyl chloride.
Plaçé à environ 30cm d'un feu très vif pendant plusieurs heures, l'appareil nta pas présenté de trace de début de fusion. Son enveloppe ne s' est pas déformée, l'hélice non plus, meme pendant les arrêts normaux de rotation. La photo-résistance, bien que très exposée à la chaleur, n'a pas changé de caractéristiques. Placed at about 30cm from a very high fire for several hours, the device did not show any trace of the start of fusion. Its envelope did not deform, neither did the propeller, even during normal rotation stops. Photo-resistance, although very exposed to heat, has not changed in characteristics.
Tous les composants ont été achetés dans le commerce local. All components were purchased locally.
