Abstract

Automatic ignition system for a gas fire, characterised in that it comprises a current inlet 1 at the terminals of a timer 2 or a programmer, which supplies: 1. an electromagnet 3 with retractable pin 14 actuating a rack which causes a toothed wheel to pivot, the spindle of which is integral with the valves and opening them, allowing the burners 7 to appear; 2. gas electrovalve 8 releasing the gas into the pipe 9 arriving at the burner 7; 3. a high-voltage current generator controlled by the switch 11 and generating a spark by means of the electrode 12 and lighting the gas of the burner 7. Application to the domestic gas-fire market.

Description

L'invention se rapporte à un allumeur automatique de
cheminée. Actuellement le procédé le plus simple pour al-
lumer un feu dans une cheminée consiste en l'utilisation
de pâte d'allumage nécessitant l'emploi de petit bois s'
enflammant facilement. L'invention vise à faciliter cet
allumage sans pâte ni petit bois.The invention relates to an automatic igniter
fireplace. Currently the simplest method for al-
lighting a fire in a fireplace consists of using
of ignition paste requiring the use of small wood
easily igniting. The invention aims to facilitate this
ignition without paste or small wood.

le système comporte une plaque pourvue d'ouvertures
obstuables par clapets actionnés par un mécanisme de com
mande dégageant des rouleurs dont l'alimentation est com
mandée pendant une durée déterminée par programmateur ou minuterie alimentant par ailleurs un dispositif d'allumage des dits brûleurs.the system has a plate with openings
obstructable by valves actuated by a communication mechanism
control releasing rollers whose supply is com
mandated for a determined period by programmer or timer supplying, moreover, an ignition device for said burners.

Le principe sera bien compris à l'aide de la description faite à titre d'exemple en regard du dessin ci-annexé qui représente
Fig 1 : vueschématique du principe d'allumage.The principle will be understood with the aid of the description given by way of example with regard to the attached drawing which represents

Le courant vient aux bornes d'une minuterie(2) qui lor eu'elle est programme alimente
10 : un électro-aimant à axe mobile (14) celui-ci actionne une crémaillère 4 faisant pivoter la roue dentée 5 dont l'axe 13 fait corps avec le clapet 6. Ce claP pet s'ouvre laissant apparaître le brûleur 7.The current comes to the terminals of a timer (2) which when it is programmed supplies
10: an electromagnet with a movable axis (14), this actuates a rack 4 which rotates the toothed wheel 5, the axis 13 of which forms a body with the valve 6. This pet valve opens, revealing the burner 7.

20 : une électro vanne de gaz 8 permettant la circuration de celui-ci par le tuyau 9 et arrivant aux brûleurs 7, par exemple un brûleur du type Chauffe-eau. 20: an electro-gas valve 8 allowing the circulation thereof by the pipe 9 and arriving at the burners 7, for example a burner of the water heater type.

30 : un générateur d!étincelles 10, du type allume gaz intégré de cuisinière par exemple. 30: a spark generator 10, of the integrated gas lighter type of stove for example.

En l'excitant par l'interrupteur 11,ou le programmateur s'en chargeant, il génère par l'électrode 12 des étincelles et enflammant le gaz, les flammes étant suffisam- ment grandes pour atteindre aisément le bois. Celui-ci posé sur des chentts permet l'ouverture des clapets 6. By exciting it with the switch 11, or the programmer taking care of it, it generates sparks by the electrode 12 and ignites the gas, the flames being large enough to easily reach the wood. This placed on chentts allows the opening of the valves 6.

En fin de programmation de la minuterie 2, ltelectrovan- ne 8 coupe l'arrivée du gaz et les clapets 6 reprennent leur position fermée grâce au ressort de rappel de l'élec t-ro-aimant lui même travaillant en mode inverse et controlé par le programmateur. At the end of programming timer 2, the solenoid valve 8 cuts off the gas supply and the valves 6 return to their closed position thanks to the return spring of the electro-magnet itself working in reverse mode and controlled by the programmer.

Un petit moteur peut remplacer la fonction de l'élec- tro aimant dans ce cas, un programmateur permettra la fermeture des clapets à la fin du temps d'allumage ou Wiffé- rant cette fermeture d'un temps nécessaire au gaz, contenu dans le tuyau d'arrivée 9, de finir de brûler. A small motor can replace the function of the electromagnet in this case, a programmer will allow the valves to close at the end of the ignition time or Wiffer this closure for a time necessary for the gas contained in the inlet pipe 9, to finish burning.

La crémaillère 4 faisant tourner la roue dertée 5, n'étant qu'un exemple d'adaptation, l'action sur les clapets 6 peut se faire à l'aide de petits leviers tirés par une tige remplacant la crémaillère 4. The rack 4 rotating the inertial wheel 5, being only an example of adaptation, the action on the valves 6 can be done using small levers pulled by a rod replacing the rack 4.

Il est égaLement possible d'actionner manuellement la crémaillère par une tirette évitant l'emploi de l'élec- tro aimant 3. It is also possible to manually actuate the rack by a pull tab avoiding the use of the electromagnet 3.

l'axe 13 des clapets 6 est décalé du centre 17 pour permettre une ouverture une ouverture plus grande sur les brûleurs 7.Cet axe 13 est également décalé en 21 ce qui permet de réduire la hauteur 22 du clapet lors de son ouverture. the axis 13 of the valves 6 is offset from the center 17 to allow an opening a larger opening on the burners 7. This axis 13 is also offset at 21 which makes it possible to reduce the height 22 of the valve when it is opened.

La surface 18 des clapets vient buter contre l'angle 19 de la plaque de fonte 15.The surface 18 of the valves abuts against the angle 19 of the cast iron plate 15.

Lors de la fermeture, la forme biseautée des faces d' appui 16 parallèles à l'axe 13 des clapets 6, permet le nettoyage intégral de la plaque de fonte 15,les faces 18 et 1 5 étant au mdme niveau. When closing, the beveled shape of the bearing faces 16 parallel to the axis 13 of the valves 6 allows complete cleaning of the cast iron plate 15, the faces 18 and 1 5 being at the same level.

Un tiroir est placé sous l'ensemble 21 pour récupérer les cendres qui peuvent éventuellement tomber par les orifices des clapets 6 lors de leur fonctionnement. A drawer is placed under the assembly 21 to recover the ashes which may possibly fall through the orifices of the valves 6 during their operation.

Les brûleurs de gaz peuvent être remplacés par un brûleur de chaudière à mazout ou tout autre type de générateur de flamme
Une sécurité peut être prévue n'autorisant l'arrivée du gaz que pour un instant déterminé. L'allumage du gaz par le brûleur 7 serait détecté par un dispositif de sécu rité ne maintenant l'arrivée du gaz que si la chaleur est captée et coupant cette arrivée de gaz, au bout du temps prévu, si l'allumage ne se produisait pas.The gas burners can be replaced by an oil boiler burner or any other type of flame generator
A safety device can be provided, authorizing the arrival of gas only for a specific time. The ignition of the gas by the burner 7 would be detected by a safety device maintaining the arrival of the gas only if the heat is captured and cutting off this arrival of gas, at the end of the scheduled time, if the ignition does not occur not.

Bien entendu un brûleur de grosse capacité peut remplacer l'ensemble des brûleurs 7 auquel cas une ouverture ou un clapet peut suffir. l'exemple des clapets 6 n'est pas limitatif, tout autre principe d'ouverture peut autre admis du genre panneau rétractable à glissière. Of course a large capacity burner can replace all of the burners 7 in which case an opening or a valve may suffice. the example of the valves 6 is not limiting, any other principle of opening can other admitted of the kind retractable sliding panel.
