Description

La présente invention concerne un dispositif de commande pour l'allumage et le réglage d'un débit de gaz d'un appareil à gaz, tel qu'un barbecue.The present invention relates to a control device for igniting and adjusting a gas flow rate of a gas appliance, such as a barbecue.

Il est connu d'utiliser un dispositif de commande ménagé dans un appareil à gaz pour réaliser l'allumage d'un mélange gaz-air en sortie d'un brûleur de l'appareil à gaz et pour contrôler le débit de gaz.It is known to use a control device formed in a gas appliance to ignite a gas-air mixture at the outlet of a burner of the gas appliance and to control the flow of gas.

L'allumage peut être réalisé par l'intermédiaire d'une électrode engendrant une étincelle permettant au mélange gaz-air de s'enflammer en sortie du brûleur. L'enclenchement de l'électrode doit donc être simultané à une alimentation du brûleur en gaz par le circuit d'alimentation.The ignition can be achieved by means of an electrode generating a spark allowing the gas-air mixture to ignite at the outlet of the burner. The engagement of the electrode must therefore be simultaneous with a supply of the gas burner by the supply circuit.

Ainsi un utilisateur de l'appareil à gaz doit veiller d'une part à utiliser le dispositif de commande pour régler un débit de gaz suffisant en tournant un organe d'ouverture et de réglage et d'autre part à enclencher l'électrode en appuyant sur un bouton. Deux commandes sont donc à réaliser de manière synchronisée, ce qui nécessite un effort d'attention de la part d'un utilisateur.Thus, a user of the gas appliance must first of all make sure that the control device is used to adjust a sufficient gas flow by turning an opening and adjusting member and secondly to switch on the electrode by pressing on a button. Two commands are to be realized in a synchronized manner, which requires an effort of attention from a user.

En effet il peut arriver que le débit de gaz soit insuffisant du fait d'un mauvais réglage manuel et que les étincelles ne permettent pas l'allumage.Indeed it may happen that the gas flow is insufficient due to manual mis-adjustment and that the sparks do not allow ignition.

Le dispositif de commande comprend généralement un organe rotatif pour le réglage du débit de gaz agencé pour être mobile entre une position de fermeture et une position de fin de course.The control device generally comprises a rotary member for adjusting the gas flow arranged to be movable between a closed position and an end position.

Pour des raisons de sécurité, il peut par exemple être nécessaire, pour passer d'un débit nul à un certain débit de gaz, d'appuyer sur l'organe rotatif pour le déplacer axialement avant de pouvoir le tourner pour commencer à alimenter en gaz.For reasons of safety, it may for example be necessary, to go from a zero flow to a certain gas flow, to press the rotary member to move axially before turning to begin to supply gas .

Il apparait donc qu'un utilisateur doit procéder à plusieurs étapes pour l'allumage : appui sur l'organe rotatif, orientation de l'organe rotatif, appui sur le bouton de l'électrode et éventuellement ajustage du débit de gaz pour permettre l'allumage.It therefore appears that a user must carry out several steps for ignition: pressing on the rotary member, orientation of the rotary member, pressing on the button of the electrode and possibly adjusting the flow of gas to allow the ignition.

La réalisation de toutes ces étapes peut s'avérer fastidieuse, notamment si l'utilisateur n'est pas dans une situation lui permettant d'accorder une attention suffisante.Achieving all these steps can be tedious, especially if the user is not in a situation allowing him to pay sufficient attention.

La présente invention vise à résoudre tout ou partie des inconvénients mentionnés ci-dessus.The present invention aims to solve all or some of the disadvantages mentioned above.

A cet effet, la présente invention concerne un dispositif de commande pour l'allumage et le réglage d'un débit de gaz d'un appareil à gaz tel qu'un barbecue comprenant un ensemble de base pourvu d'un contacteur d'allumage et/ou d'un contacteur d'indication de combustion, et un organe d'ouverture et de réglage d'un débit de gaz agencé pour coopérer avec l'ensemble de base de manière à être alternativement disposé en une configuration de verrouillage de fermeture et en une configuration de contrôle du débit de gaz d'une part, et de manière à être déplaçable entre une position de fermeture et une position de fin de course d'autre part.For this purpose, the present invention relates to a control device for igniting and adjusting a gas flow rate of a gas appliance such as a barbecue comprising a base assembly provided with an ignition switch and / or a combustion indication contactor, and an opening and regulating member of a gas flow arranged to cooperate with the base assembly so as to be alternately arranged in a closed locking configuration and in a control configuration of the gas flow on the one hand, and so as to be movable between a closed position and an end position on the other hand.

L'organe d'ouverture et de réglage est déplaçable entre la position de fermeture et la position de fin de course en configuration de contrôle uniquement.The opening and adjusting member is movable between the closed position and the end position in control configuration only.

L'organe d'ouverture et de réglage est apte à être disposé alternativement en configuration de contrôle et en configuration de verrouillage de fermeture en position de fermeture uniquement.The opening and adjusting member is adapted to be arranged alternately in the control configuration and in the closed locking configuration in the closed position only.

L'organe d'ouverture et de réglage est agencé, lors d'un déplacement de la position de fermeture à la position de fin de course, pour passer par une zone d'allumage dans laquelle l'organe d'ouverture et de réglage coopère avec le contacteur d'allumage et/ou pour passer par une zone d'indication de combustion dans laquelle l'organe d'ouverture et de réglage coopère avec le contacteur d'indication de combustion.The opening and adjusting member is arranged, during a movement from the closed position to the end position, to pass through an ignition zone in which the opening and adjusting member cooperates with the ignition switch and / or to pass through a combustion indication zone in which the opening and adjusting member cooperates with the combustion indication switch.

Lors du déplacement de l'organe d'ouverture et de réglage de la position de fermeture à la position de fin de course, le débit de gaz est tout d'abord nul puis augmente jusqu'à un maximum pour ensuite diminuer progressivement jusqu'à un débit faible en position de fin de course.When moving the opening and adjusting member from the closed position to the end position, the gas flow is first zero and then increases to a maximum and then gradually decreases to low flow in the end position.

Dans la zone d'allumage, sous l'effet de l'enclenchement du contacteur d'allumage, un dispositif d'allumage comme une électrode peut être prévu pour être actif dans le but d'enflammer un mélange gaz-air.In the ignition zone, under the effect of the engagement of the ignition switch, an ignition device such as an electrode may be provided to be active in order to ignite a gas-air mixture.

Dans la zone d'indication de combustion, une flamme est déjà allumée et l'alimentation en gaz peut être régulée en déplaçant l'organe de d'ouverture et de réglage. Un indicateur de combustion peut également être prévu de manière à être actif lors de l'enclenchement du contacteur d'indication de combustion.In the combustion indication zone, a flame is already lit and the gas supply can be regulated by moving the opening and adjusting member. A combustion indicator may also be provided to be operative upon engagement of the combustion indication switch.

Selon un aspect de l'invention, l'ensemble de base est pourvu d'un contacteur d'allumage et d'un contacteur d'indication de combustion ; l'organe d'ouverture et de réglage étant agencé, lors d'un déplacement de la position de fermeture à la position de fin de course, pour passer par la zone d'allumage et pour passer par une zone d'indication de combustion.According to one aspect of the invention, the base assembly is provided with an ignition switch and a combustion indication switch; the opening and adjusting member being arranged, during a displacement of the position of closing at the end position, to pass through the ignition zone and to pass through a combustion indication zone.

L'organe d'ouverture et de réglage a pour rôle non seulement d'autoriser l'émission d'un débit de gaz et de permettre son réglage mais aussi d'engendrer l'allumage puis de signaler à l'utilisateur que l'allumage a bien eu lieu et qu'une flamme est normalement engendrée.The role of the opening and adjusting member is not only to authorize the emission of a gas flow and to allow its adjustment, but also to generate the ignition and then to signal to the user that the ignition has taken place and a flame is normally generated.

L'utilisateur n'a donc qu'un seul organe à manipuler : l'organe d'ouverture et de réglage. Cette disposition est particulièrement intéressante car d'une seule main, l'utilisateur peut procéder à l'allumage de l'appareil à gaz.The user therefore has only one organ to handle: the opening and adjusting member. This arrangement is particularly interesting because with one hand, the user can proceed with the ignition of the gas appliance.

Selon un aspect de l'invention, la zone d'allumage et la zone d'indication de combustion présentent une portion commune ou sont totalement distinctes.According to one aspect of the invention, the ignition zone and the combustion indication zone have a common portion or are totally distinct.

Lors d'un déplacement de la position de fermeture à la position de fin de course, la zone d'allumage est atteinte en premier et la zone d'indication de combustion est atteinte en second.When moving from the closed position to the end position, the ignition zone is reached first and the combustion indication zone is reached second.

Ainsi lorsque le contacteur d'indication de combustion est fermé, l'étape d'allumage est terminée : une flamme est censée être engendrée. Si ce n'est pas le cas, un indicateur peut être utilisé en coopération avec le contacteur d'indication de combustion. Soit l'indicateur permet à l'utilisateur de vérifier qu'une flamme est bien émise, soit l'indicateur permet à l'utilisateur de se rendre compte d'un dysfonctionnement. C'est le cas par exemple si la flamme a été soufflée par le vent.Thus, when the combustion indication switch is closed, the ignition step is over: a flame is supposed to be generated. If this is not the case, an indicator may be used in cooperation with the combustion indication contactor. Either the indicator allows the user to verify that a flame is emitted or the indicator allows the user to realize a malfunction. This is the case for example if the flame has been blown by the wind.

De préférence, la zone d'allumage est atteinte dès que l'organe d'ouverture et de réglage quitte la position de fermeture. Ainsi l'allumage peut être engendré dès qu'un débit de gaz apparait.Preferably, the ignition zone is reached as soon as the opening and adjusting member leaves the closed position. Thus ignition can be generated as soon as a gas flow appears.

Selon un aspect de l'invention, l'organe d'ouverture et de réglage comprend un élément de transformation de mouvement agencé pour enclencher par contact le contacteur d'allumage et/ou le contacteur d'indication de combustion lorsque l'organe d'ouverture et de réglage est dans la zone d'allumage et/ou respectivement lorsque l'organe d'ouverture et de réglage est dans la zone d'indication de combustion.According to one aspect of the invention, the opening and adjusting member comprises a movement transformation element arranged to engage the ignition switch and / or the combustion indication contactor when the opening and setting is in the ignition zone and / or respectively when the opening and adjusting member is in the combustion indication zone.

Selon un aspect de l'invention, le déplacement de l'organe d'ouverture et de réglage entre la position de fermeture et la position de fin de course correspond à une modification de l'orientation de l'organe d'ouverture et de réglage selon un axe d'extension dudit organe.According to one aspect of the invention, the displacement of the opening and adjustment member between the closed position and the end position corresponds to a modification of the orientation of the opening and adjusting member. along an extension axis of said member.

L'organe d'ouverture et de réglage est un organe rotatif d'utilisation simple. Ainsi, l'utilisateur peut distinguer facilement s'il est dans la zone d'allumage ou la zone d'indication de combustion selon l'orientation de l'organe d'ouverture et de réglage.The opening and adjusting member is a rotary member of simple use. Thus, the user can easily distinguish whether he is in the ignition zone or the combustion indication zone according to the orientation of the opening and adjusting member.

En particulier, l'organe d'ouverture et de réglage comprend un marquage agencé pour indiquer une orientation par rapport à l'axe d'extension. L'utilisateur peut ainsi déterminer facilement s'il est dans la zone d'allumage ou la zone d'indication de combustion.In particular, the opening and adjusting member comprises a marking arranged to indicate an orientation relative to the axis of extension. The user can thus easily determine if he is in the ignition zone or the combustion indication zone.

Ce marquage permet également à l'utilisateur de connaitre le réglage du débit de gaz.This marking also allows the user to know the regulation of the gas flow.

Selon un aspect de l'invention, l'organe de transformation de mouvement est une came présentant une première portion agencée pour coopérer avec le contacteur d'allumage et/ou une deuxième portion agencée pour coopérer avec le contacteur d'indication de combustion.According to one aspect of the invention, the movement transformation member is a cam having a first portion arranged to cooperate with the ignition switch and / or a second portion arranged to cooperate with the combustion indication contactor.

Cette disposition permet de définir la zone d'allumage et la zone d'indication de combustion précisément en fonction de la géométrie de la came.This arrangement makes it possible to define the ignition zone and the combustion indication zone precisely as a function of the geometry of the cam.

Selon un aspect de l'invention, l'organe d'ouverture et de réglage est agencé pour coopérer avec l'ensemble de base de manière être déplaçable entre une première position correspondant à la configuration de verrouillage de fermeture et une deuxième position correspondant à la configuration de contrôle du débit de gaz.According to one aspect of the invention, the opening and adjusting member is arranged to cooperate with the base assembly so as to be movable between a first position corresponding to the closure locking configuration and a second position corresponding to the gas flow control configuration.

Ainsi, l'utilisateur peut contrôler aisément le passage de la configuration de verrouillage de fermeture à la configuration de contrôle de débit de gaz.Thus, the user can easily control the transition from the closed lock configuration to the gas flow control configuration.

Il est également facile à l'utilisateur de savoir dans quelle configuration il se trouve selon le positionnement en première ou deuxième position.It is also easy for the user to know in which configuration he is according to the positioning in first or second position.

Selon un aspect de l'invention, l'organe d'ouverture et de réglage est agencé pour être déplacé entre la première position et la deuxième position selon l'axe d'extension dudit organe d'ouverture et de réglage.According to one aspect of the invention, the opening and adjusting member is arranged to be moved between the first position and the second position along the axis of extension of said opening and adjusting member.

Le déplacement axial de l'organe d'ouverture et de réglage est facilement réalisable et permet de passer sans encombre de la configuration de verrouillage de fermeture à la configuration de contrôle de débit de gaz.The axial displacement of the opening and adjusting member is easily achievable and makes it possible to pass smoothly from the closure lock configuration to the gas flow control configuration.

Selon un aspect de l'invention, le dispositif de commande comprend un élément de retenue agencé pour appliquer à l'organe d'ouverture et de réglage et/ou à un élément solidaire en déplacement de l'organe d'ouverture et de réglage, une contrainte visant à passer de la configuration de contrôle à la configuration de verrouillage de fermeture.According to one aspect of the invention, the control device comprises a retaining element arranged to apply to the opening member and adjusting and / or a movable integral member in movement of the opening and adjusting member, a constraint for passing from the control pattern to the closing lock configuration.

Ainsi, l'organe d'ouverture et de réglage est bloqué physiquement par le guidage, ce qui participe à la fiabilité de l'alimentation en gaz et au maintien de la fermeture.Thus, the opening and adjustment member is physically blocked by the guide, which contributes to the reliability of the gas supply and the maintenance of the closure.

Il est donc impossible de faire tourner l'organe d'ouverture et de réglage en configuration de verrouillage de fermeture. Il faut au préalable appuyer sur l'organe d'ouverture et de réglage pour passer en configuration de contrôle et ainsi pouvoir allumer le brûleur.It is therefore impossible to rotate the opening and adjusting member in closing lock configuration. It is necessary first to press on the opening and adjustment device to go into control configuration and thus be able to ignite the burner.

Comme illustré à la figure 1, un appareil à gaz 1 tel qu'un barbecue 3 comprend un circuit d'alimentation en gaz, quatre brûleurs 5 et un système d'allumage et de contrôle 7 d'un débit de gaz pourvu d'un dispositif de commande 9 par brûleur 5.As illustrated in figure 1 a gas appliance 1 such as a barbecue 3 comprises a gas supply circuit, four burners 5 and an ignition and control system 7 of a gas flow provided with a control device 9 by a burner 5.

Le système d'allumage et de contrôle 7 comprend une vanne de réglage d'un débit de gaz ménagée dans une portion du circuit d'alimentation et agencée pour être déplaçable entre une position ouverte et une position fermée de manière à contrôler le débit de gaz entre une valeur nulle en position fermée et une valeur maximale en position ouverte.The ignition and control system 7 comprises a gas flow control valve arranged in a portion of the supply circuit and arranged to be movable between an open position and a closed position so as to control the flow of gas. between a zero value in the closed position and a maximum value in the open position.

Le système d'allumage et de contrôle 7 comprend un élément d'allumage 11 agencé pour engendrer un apport d'énergie visant à allumer un mélange gaz-air. Dans le mode de réalisation présenté, il s'agit d'une électrode 13 agencée pour produire des étincelles.The ignition and control system 7 comprises an ignition element 11 arranged to generate a supply of energy to ignite a gas-air mixture. In the embodiment shown, it is an electrode 13 arranged to produce sparks.

Le système d'allumage et de contrôle 7 comprend également un indicateur 15 par brûleur 5, chacun étant agencé pour fournir une indication visuelle lorsqu'une flamme est engendrée ou est censée être engendrée par le brûleur 5 correspondant.The ignition and control system 7 also includes a burner indicator 5, each arranged to provide a visual indication when a flame is generated or is expected to be generated by the corresponding burner.

Dans le mode de réalisation présenté l'indicateur 15 est une source lumineuse qui est agencée pour être active lorsqu'une flamme est engendrée ou est censée être engendrée.In the embodiment shown indicator 15 is a light source which is arranged to be active when a flame is generated or is expected to be generated.

Comme illustré aux figures 2, 3, 4a à 4e, 5a à 5e et 6a à 6e, le dispositif de commande 9 comprend un ensemble de base 17 ménagé dans l'appareil à gaz 1. Le dispositif de commande 9 est agencé pour commander l'allumage et le réglage d'un débit de gaz du brûleur 5 correspondant.As illustrated in Figures 2, 3, 4a to 4e, 5a to 5e and 6a to 6e , the control device 9 comprises a base assembly 17 formed in the gas appliance 1. The control device 9 is arranged to control the ignition and adjustment of a gas flow of the corresponding burner 5.

L'ensemble de base 17 comprend un contacteur d'allumage 19 relié à un élément d'allumage 11 correspondant, l'enclenchement du contacteur d'allumage 19 ayant pour effet d'engendrer des étincelles de manière régulière.The base assembly 17 comprises an ignition switch 19 connected to a corresponding ignition element 11, the engagement of the ignition switch 19 having the effect of generating sparks in a regular manner.

L'ensemble de base 17 comprend également un contacteur d'indication de combustion 21, l'enclenchement du contacteur d'indication de combustion 21 ayant pour effet de faire fonctionner l'indicateur 15.The base assembly 17 also includes a combustion indication switch 21, the engagement of the combustion indication switch 21 having the effect of operating the indicator 15.

Le dispositif de commande 9 comprend en outre un organe d'ouverture et de réglage 23 agencé pour coopérer avec l'ensemble de base 17 et ayant pour rôle :

  • d'une part de définir soit une configuration de verrouillage de fermeture VF, comme illustrée à la figure 2, dans laquelle le circuit d'alimentation est maintenu fermé pour le brûleur 5 correspondant soit une configuration de contrôle CC de débit de gaz, comme illustrée à la figure 3, dans laquelle le maintien en position fermée n'est plus réalisé,
  • d'autre part de permettre le réglage d'un débit de gaz alimentant le brûleur 5 correspondant, ce réglage n'étant possible qu'en configuration de contrôle CC de débit de gaz.
The control device 9 further comprises an opening and adjusting member 23 arranged to cooperate with the base assembly 17 and having the role:
  • on the one hand to define either a closed locking configuration VF, as illustrated in FIG. figure 2 in which the supply circuit is kept closed for the burner 5 corresponding to a gas flow control DC configuration, as illustrated in FIG. figure 3 in which the holding in the closed position is no longer achieved,
  • on the other hand to allow the adjustment of a gas flow supplying the corresponding burner 5, this setting being only possible in the control configuration CC gas flow.

Comme illustré aux figures 2 et 3, la configuration de fermeture VF est définie par une première position de l'organe d'ouverture et de réglage 23 et la configuration de contrôle CC par une deuxième position, chaque position étant considérée par rapport à l'axe d'extension 25 de l'organe d'ouverture et de réglage 23.As illustrated in Figures 2 and 3 , the closure configuration VF is defined by a first position of the opening and adjusting member 23 and the control configuration CC by a second position, each position being considered with respect to the extension axis 25 of the opening and adjusting member 23.

L'organe d'ouverture et de réglage 23 est également agencé pour être déplacé entre une position de fermeture et une position de fin de course.The opening and adjusting member 23 is also arranged to be moved between a closed position and an end position.

Le déplacement de l'organe d'ouverture et de réglage 23 entre la position de fermeture et la position de fin de course correspondant à une orientation de l'organe d'ouverture et de réglage 23 autour de l'axe d'extension 25.The displacement of the opening and adjusting member 23 between the closed position and the end-of-travel position corresponding to an orientation of the opening and adjusting member 23 around the extension axis 25.

Lors du déplacement de l'organe d'ouverture et de réglage 23 de la position de fermeture à la position de fin de course, le débit de gaz est tout d'abord nul puis augmente jusqu'à un maximum pour ensuite diminuer progressivement jusqu'à un débit faible en position de fin de course.During the displacement of the opening and adjustment member 23 from the closed position to the end position, the gas flow rate is first zero and then increases to a maximum and then gradually decreases to at a low flow rate in the end position.

Pour permettre le passage d'une configuration à l'autre et la modulation du débit d'alimentation en gaz, l'ensemble de base 17 présente un guidage 27. Ce guidage 27 est agencé de manière à ce que :

  • l'organe d'ouverture et de réglage 23 soit déplaçable entre la position de fermeture et la position de fin de course en configuration de contrôle CC uniquement,
  • l'organe d'ouverture et de réglage 23 soit apte à être disposé alternativement en configuration de contrôle CC et en configuration de verrouillage VF de fermeture en position de fermeture uniquement.
To allow the passage from one configuration to another and the modulation of the gas supply flow, the base assembly 17 has a guide 27. This guide 27 is arranged so that:
  • the opening and adjusting member 23 is movable between the closed position and the end position in CC control configuration only,
  • the opening and adjusting member 23 is adapted to be arranged alternately in the DC control configuration and in the closed locking configuration VF in the closed position only.

Pour coopérer avec le guidage 27, l'organe d'ouverture et de réglage 23 présente un ergot 29.To cooperate with the guide 27, the opening and adjusting member 23 has a lug 29.

En outre, l'ensemble de base 17 comprend un élément de retenue 31 agencé pour appliquer une contrainte 33 sur l'organe d'ouverture et de réglage23 visant à passer de la configuration de contrôle CC à la configuration de verrouillage de fermeture VF.In addition, the base assembly 17 includes a retaining member 31 arranged to apply a stress 33 to the opening and adjusting member 23 to change from the DC control pattern to the VF lock lock configuration.

Ainsi, en position de fermeture et en l'absence de sollicitation d'un utilisateur, l'organe d'ouverture et de réglage 23 passe automatiquement de la configuration de contrôle CC à la configuration de verrouillage de fermeture VF.Thus, in the closed position and in the absence of a request from a user, the opening and adjusting member 23 automatically switches from the control configuration CC to the closing lock configuration VF.

L'organe d'ouverture et de réglage 23 comprend également un élément de transformation de mouvement 35 agencé pour coopérer en configuration de contrôle CC avec le contacteur d'allumage 19 et/ou le contacteur d'indication de combustion 21.The opening and adjusting member 23 also comprises a movement transformation element 35 arranged to cooperate in the DC control configuration with the ignition switch 19 and / or the combustion indication switch 21.

Dans le mode de réalisation présenté, l'élément de transmission de mouvement 35 est une came 37 présentant une première portion 37a agencée pour coopérer avec le contacteur d'allumage 19 et une deuxième portion 37b agencée pour coopérer avec le contacteur d'indication de combustion 21.In the embodiment shown, the motion transmission element 35 is a cam 37 having a first portion 37a arranged to cooperate with the ignition switch 19 and a second portion 37b arranged to cooperate with the ignition indication contactor 21.

La coopération entre un contacteur 19, 21 et une portion 37a, 37b correspondante signifie que la portion 37a, 37b entre en contact avec le contacteur 19, 21 de manière à l'enclencher.The cooperation between a contactor 19, 21 and a corresponding portion 37a, 37b means that the portion 37a, 37b comes into contact with the switch 19, 21 so as to engage it.

La coopération entre un contacteur 19, 21 et une portion 37a, 37b correspondante dépend de la position, c'est-à-dire de l'orientation, de l'organe d'ouverture et de réglage 23.The cooperation between a contactor 19, 21 and a corresponding portion 37a, 37b depends on the position, that is to say on the orientation, of the opening and adjusting member 23.

On distingue ainsi une zone d'allumage ZA qui correspond à l'ensemble des positions ou orientations dans lesquelles le contacteur d'allumage 19 est enclenché et une zone d'indication de combustion ZI qui correspond aux positions dans lesquelles le contacteur d'indication de combustion 21 est enclenché.There is thus an ignition zone ZA which corresponds to all the positions or orientations in which the ignition switch 19 is engaged and a combustion indication zone ZI which corresponds to the positions in which the ignition contactor Z1 combustion 21 is switched on.

La zone d'allumage ZA et la zone d'indication de combustion ZI correspondent donc chacune à des secteurs angulaires. L'organe d'ouverture et de réglage 23 peut comprendre un marquage 39 permettant de savoir dans quel secteur angulaire il est disposé. La zone d'allumage ZA et la zone d'indication de combustion ZI peuvent être distinctes, contigüe ou présenter une portion commune.The ignition zone ZA and the combustion indication zone ZI therefore each correspond to angular sectors. The opening and adjusting member 23 may comprise a marking 39 to know in which angular sector it is arranged. The ignition zone ZA and the combustion indication zone ZI may be distinct, contiguous or have a common portion.

On a représenté aux figures 4a à 4e, 5a à 5e et 6a à 6e une séquence d'allumage et de réglage du débit de gaz.Representatives FIGS. 4a to 4e, 5a to 5e and 6a at 6 e a sequence of ignition and adjustment of the gas flow.

Aux figures 4a, 5a et 6a, l'organe d'ouverture et de réglage 23 est en configuration de verrouillage de fermeture VF et en position de fermeture.To the FIGS. 4a, 5a and 6a , the opening and adjusting member 23 is in the closed locking configuration VF and in the closed position.

Aux figures 4b, 5b et 6b, l'organe d'ouverture et de réglage 23 est en configuration de contrôle CC et en position de fermeture : le débit de gaz est nul, aucun des contacteurs 19, 21 n'est enclenché.To the Figures 4b, 5b and 6b , the opening and adjusting member 23 is in DC control configuration and in the closed position: the gas flow is zero, none of the contactors 19, 21 is engaged.

Le passage de la configuration de verrouillage de fermeture VF à la configuration de contrôle CC a pour effet d'aligner axialement les contacteurs 19, 21 et la came 37.The transition from the closing lock configuration VF to the DC control configuration has the effect of axially aligning the contactors 19, 21 and the cam 37.

Aux figures, 4c, 5c et 6c, la vanne de gaz est ouverte de manière à ce qu'un débit adéquat pour l'allumage soit engendré. L'organe d'ouverture et de réglage 23 est également dans la zone d'allumage ZA, ce qui a pour conséquence d'engendrer le fonctionnement de l'électrode 13.To the figures, 4c, 5c and 6c , the gas valve is opened so that a suitable flow rate for ignition is generated. The opening and adjusting member 23 is also in the ignition zone ZA, which has the consequence of causing the operation of the electrode 13.

Lorsque le contacteur d'allumage 19 est enclenché, l'électrode 13 fonctionne en produisant des étincelles de manière régulière.When the ignition switch 19 is engaged, the electrode 13 operates by producing sparks in a regular manner.

Aux figures 4d, 5d et 6d tout comme aux figures 4e, 5e et 6e, l'organe d'ouverture et de réglage 23 est en zone d'indication de combustion ZI.To the Figures 4d, 5d and 6d just like figures 4th, 5th and 6th , the opening and adjusting member 23 is in combustion indication zone ZI.

Puisque un débit de gaz est émis et que l'allumage s'est produit précédemment, l'utilisateur règle le débit de gaz de manière à ajuster la flamme. Comme le contacteur d'indication de combustion 21 est enclenché l'indicateur 15 est en fonctionnement.Since a gas flow is emitted and ignition has occurred previously, the user adjusts the gas flow to adjust the flame. As the combustion indication switch 21 is engaged the indicator 15 is in operation.

Il ressort de la présente description que l'allumage et le réglage de la flamme par la modulation du débit de gaz peuvent être réalisés aisément par un utilisateur, par exemple en n'utilisant qu'une seule main.It is clear from the present description that the ignition and adjustment of the flame by the modulation of the gas flow can be easily achieved by a user, for example using only one hand.

En effet, l'allumage qui peut s'avérer compliqué avec des systèmes dans lesquels il faut de manière synchronisée d'une main ajuster le débit de gaz et de l'autre mettre en marche l'électrode.Indeed, the ignition can be complicated with systems in which it is necessary to synchronize one hand to adjust the gas flow and the other start the electrode.

Le présent dispositif de commande 9 permet ainsi un allumage fiable car un débit correspondant au débit idéal pour l'allumage est engendré lorsque l'organe d'ouverture et de réglage est en zone d'allumage ZA. En même temps, l'électrode 13 fonctionne en émettant des étincelles régulièrement.The present control device 9 thus allows reliable ignition because a flow rate corresponding to the ideal flow rate for ignition is generated when the opening and adjusting member is in the ignition zone ZA. At the same time, the electrode 13 operates by emitting sparks regularly.

Un autre avantage est l'allumage de la lumière de l'indicateur 15 après l'allumage de la flamme. Cette disposition est importante car elle permet à un utilisateur de savoir si un brûleur 5 est allumé ou non.Another advantage is the lighting of the indicator light 15 after ignition of the flame. This provision is important because it allows a user to know if a burner 5 is lit or not.

En effet, lorsqu'un appareil à gaz 1 tel qu'un barbecue 3 est utilisé, selon l'éclairage ambiant, il peut s'avérer difficile de distinguer la flamme en sortie du brûleur. Ceci est d'autant plus vrai qu'un support et/ou une plaque sont disposés au dessus du brûleur 5.Indeed, when a gas appliance 1 such as a barbecue 3 is used, depending on the ambient light, it can be difficult to distinguish the flame output burner. This is all the more true that a support and / or a plate are arranged above the burner 5.

Un autre avantage lié à cet indicateur 15 est de pouvoir s'assurer que le feu a bien été éteint après l'utilisation de l'appareil à gaz 1. Le risque de laisser le gaz ouvert, ce qui peut avoir pour conséquence le soufflement de la flamme et l'émission de gaz, est donc limité.Another advantage related to this indicator 15 is to be able to ensure that the fire has been extinguished after the use of the gas appliance 1. The risk of leaving the gas open, which may result in the blowing of gas. the flame and the emission of gas, is therefore limited.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif de commande, décrit ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation.As goes without saying, the invention is not limited to the sole embodiment of this control device, described above as an example, it encompasses all the variants.
