Ces moyens de commande sont constitués classiquement de touches de commande disposées au niveau d'un bandeau de commande associé à l'appareil de cuisson.These control means are conventionally constituted by control keys arranged at a control panel associated with the cooking appliance.

De plus en plus fréquemment, ces touches sont des touches sensitives, disposées sous une plaque électriquement isolante de l'appareil de cuisson et adaptées à détecter la présence d'un doigt de l'utilisateur en regard de cette touche pour commander le fonctionnement d'un ou plusieurs moyens de chauffage.More and more frequently, these keys are sensitive keys arranged under an electrically insulating plate of the cooking appliance and adapted to detect the presence of a finger of the user opposite this key to control the operation of the appliance. one or more heating means.

Il est connu d'associer à ces moyens de commande en fonctionnement d'un appareil de cuisson, des touches de réglage d'une ou plusieurs minuteries adaptées à commander l'horloge de la ou des minuteries, de telle sorte que leur actionnement par l'utilisateur permet d'ajuster la durée de fonctionnement d'un ou plusieurs moyens de chauffage.It is known to associate with these control means in operation of a cooking appliance, adjustment keys of one or more timers adapted to control the clock of the timer or timers, so that their actuation by the The user can adjust the operating time of one or more heating means.

En particulier, ces touches de réglage d'une ou plusieurs minuteries permettent d'allonger ou de raccourcir la durée de fonctionnement d'un ou plusieurs moyens de chauffage à tout instant dès lors qu'au moins une de ces minuteries est activée.In particular, these adjustment buttons of one or more timers can lengthen or shorten the operating time of one or more heating means at any time when at least one of these timers is activated.

Suivant les différents appareils de cuisson, l'appareil de cuisson comprend une minuterie associée à l'ensemble des moyens de chauffage permettant de déterminer la durée de fonctionnement de manière commune de tous les moyens de chauffage, ou l'appareil de cuisson comprend une minuterie associée à l'ensemble des moyens de chauffage permettant de déterminer la durée de fonctionnement de chacun des moyens de chauffage par une sélection du moyen de chauffage, ou encore l'appareil de cuisson comprend une minuterie associée à chacun des moyens de chauffage.According to the different cooking appliances, the cooking appliance comprises a timer associated with all the heating means making it possible to determine the operating time in common of all the heating means, or the cooking appliance comprises a timer. associated with the set of heating means for determining the operating time of each of the heating means by a selection of the heating means, or the cooking apparatus comprises a timer associated with each of the heating means.

L'utilisateur peut ainsi régler une ou plusieurs minuteries en ajoutant ou en soustrayant une durée de fonctionnement d'au moins un moyen de chauffage.The user can thus set one or more timers by adding or subtracting an operating time of at least one heating means.

Cependant, les moyens de commande d'une ou plusieurs minuteries ne permettent pas à l'utilisateur de connaître le temps de fonctionnement d'un ou plusieurs moyens de chauffage depuis la mise en fonctionnement du ou des moyens de chauffage.However, the control means of one or more timers do not allow the user to know the operating time of one or more heating means since the operation of the heating means or means.

Lorsqu'un utilisateur oublie de régler une minuterie au début d'une mise en fonctionnement d'au moins un moyen de chauffage ou au cours de la mise en fonctionnement de ces derniers, l'utilisateur ne peut savoir depuis combien de temps la mise en fonctionnement d'au moins un moyen de chauffage a été commencée ou modifiée.When a user forgets to set a timer at the beginning of a setting operation of at least one heating means or during operation of the latter, the user can not know how long the operation of at least one heating means has been started or modified.

Par conséquent, l'utilisateur ne peut pas définir une durée de fonctionnement restante d'au moins un moyen de chauffage nécessaire à la cuisson des aliments.Therefore, the user can not set a remaining operating time of at least one heating means necessary for cooking food.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un procédé de commande d'au moins un moyen de chauffage d'un appareil de cuisson présentant une meilleure ergonomie d'utilisation.The present invention aims to solve the aforementioned drawbacks and to provide a method of controlling at least one heating means of a cooking appliance having a better ergonomics of use.

A cet effet, la présente invention vise un procédé de commande d'au moins un moyen de chauffage d'un appareil de cuisson, ledit appareil de cuisson comportant au moins une minuterie.For this purpose, the present invention provides a method of controlling at least one heating means of a cooking appliance, said cooking appliance having at least one timer.

Selon l'invention, ledit procédé comprend au moins les étapes suivantes :

  • acquisition d'une commande de mise en fonctionnement dudit au moins un moyen de chauffage ;
  • mémorisation d'une durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage depuis l'acquisition de la commande de mise en fonctionnement dudit au moins un moyen de chauffage sans réglage de ladite au moins une minuterie et/ou une acquisition d'une commande de modification d'au moins un paramètre de fonctionnement dudit au moins un moyen de chauffage sans réglage de ladite au moins une minuterie ;
  • acquisition d'une commande d'affichage de la durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage ; et
  • affichage de la durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage.
According to the invention, said method comprises at least the following steps:
  • acquiring an operation control of said at least one heating means;
  • storing an elapsed operating time Te of said at least one heating means since the acquisition of the operation command of said at least one heating means without adjustment of said at least one timer and / or an acquisition of a control for modifying at least one operating parameter of said at least one heating means without adjusting said at least one timer;
  • acquisition of a display command of the elapsed operating time Te of said at least one heating means; and
  • display of the elapsed operating time Te of said at least one heating means.

Ainsi, la durée de fonctionnement écoulée Te d'au moins un moyen de chauffage depuis la mise en fonctionnement dudit au moins un moyen de chauffage ou la modification d'un paramètre de fonctionnement de ce dernier peut être déterminée et affichée suite à la demande par l'utilisateur par l'activation d'un moyen de commande sans qu'une minuterie n'ait été réglée préalablement.Thus, the elapsed operating time Te of at least one heating means since the operation of said at least one heating means or the modification of an operating parameter of the latter can be determined and displayed following the request by the user by activating a control means without a timer having been previously set.

L'utilisateur est informé de la durée de fonctionnement écoulée d'au moins un moyen de chauffage et ainsi en déduire la durée de fonctionnement restante Tr nécessaire pour la cuisson des aliments sans risque que les aliments soient surcuits ou encore pas assez cuits.The user is informed of the elapsed operating time of at least one heating means and thus deduce the remaining operating time Tr necessary for cooking food without risk that the food is overcooked or not sufficiently cooked.

Selon une caractéristique préférée de l'invention, ledit procédé comprend au moins l'étape suivante : acquisition d'une durée de fonctionnement restante Tr dudit au moins un moyen de chauffage.According to a preferred feature of the invention, said method comprises at least the following step: acquisition of a remaining operating time Tr of said at least one heating means.

Ainsi, l'utilisateur peut connaître la durée de fonctionnement écoulée Te depuis le début de la mise en fonctionnement d'au moins un moyen de chauffage ou de la modification d'au moins un paramètre de fonctionnement dudit au moins un moyen de chauffage puis ajuster une durée de fonctionnement restante Tr en fonction de l'état d'avancement de la cuisson des aliments.Thus, the user can know the elapsed operating time Te since the start of the operation of at least one heating means or the modification of at least one operating parameter of said at least one heating means and then adjust a remaining operating time Tr according to the state of progress of cooking food.

De cette manière, la durée de fonctionnement restante Tr dudit au moins un moyen de chauffage s'écoulera jusqu'à la fin de cette durée et ledit au moins un moyen de chauffage de l'appareil de cuisson sera arrêté.In this way, the remaining operating time Tr of said at least one heating means will flow until the end of this period and said at least one heating means of the cooking appliance will be stopped.

Cette durée de fonctionnement restante Tr dudit au moins un moyen de chauffage permet de terminer une cuisson des aliments suite à un oubli de réglage d'une minuterie par l'utilisateur sans que lesdits aliments soient surcuits ou encore pas assez cuits.This remaining operating time Tr of said at least one heating means makes it possible to complete a cooking of the foods following a forgetfulness of setting a timer by the user without said foods being overcooked or not sufficiently cooked.

L'acquisition d'une durée de fonctionnement restante Tr dudit au moins un moyen de chauffage est mise en oeuvre si la durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage est inférieure à la durée de cuisson totale souhaitée Tf.The acquisition of a remaining operating time Tr of said at least one heating means is carried out if the elapsed operating time Te of said at least one heating means is less than the total desired cooking time Tf.

Les moyens de commande 4 d'au moins une minuterie permettent à l'utilisateur d'ajuster la durée de fonctionnement totale Tf dudit au moins un moyen de chauffage 2 en réalisant des appuis sur les touches représentées « + » et « - » à la figure 1.The control means 4 of at least one timer allow the user to adjust the total operating time Tf of said at least one heating means 2 by pressing the keys represented by "+" and "-" on the figure 1 .

Si la durée de fonctionnement écoulée Te dudit au moins un chauffage 2 est inférieure à la durée de cuisson totale souhaitée Tf, l'utilisateur peut ainsi ajuster la durée de fonctionnement restante Tr d'au moins un moyen de chauffage 2 en appuyant sur une touche de commande 4 en fonctionnement d'au moins une minuterie de sorte à indiquer la durée de cuisson totale souhaitée Tf.If the elapsed operating time Te of said at least one heating 2 is less than the total desired cooking time Tf, the user can thus adjust the remaining operating time Tr of at least one heating means 2 by pressing a key 4 during operation of at least one timer so as to indicate the desired total cooking time Tf.

Le procédé de commande comprend ensuite une étape E6 d'affichage de la durée de fonctionnement restante Tr dudit au moins un moyen de chauffage 2.The control method then comprises a step E6 of displaying the remaining operating time Tr of said at least one heating means 2.

Les moyens d'affichage 10 permettent d'afficher la durée de fonctionnement totale Tf dudit au moins un moyen de chauffage 2 pendant une durée prédéterminée, par exemple de l'ordre de trois secondes, suite à l'acquisition par l'utilisation d'une durée de fonctionnement restante Tr dudit au moins un moyen de chauffage 2 si la durée de fonctionnement écoulée Te dudit au moins un chauffage 2 est inférieure à la durée de cuisson totale souhaitée Tf.The display means 10 make it possible to display the total operating time Tf of said at least one heating means 2 for a predetermined duration, for example of the order of three seconds, following the acquisition by the use of a remaining operating time Tr of said at least one heating means 2 if the elapsed operating time Te of said at least one heating 2 is less than the total desired cooking time Tf.

Puis les moyens d'affichage 10 affichent la durée de fonctionnement restante Tr dudit au moins un moyen de chauffage 2.Then the display means 10 display the remaining operating time Tr of said at least one heating means 2.

Après validation de la durée de cuisson totale souhaitée Tf, par exemple suite à une période d'absence de détection de commande sur une touche de commande du clavier de commande 7, la durée de fonctionnement restante Tr est affichée par des moyens d'affichage 10 d'au moins une minuterie. Ladite au moins une minuterie est ainsi paramétrée et des moyens de décompte peuvent permettre de couper automatiquement l'alimentation en énergie d'un ou plusieurs moyens de chauffage 2 après l'écoulement de ladite durée paramétrée.After validation of the desired total cooking time Tf, for example following a period of absence of control detection on a control key of the control keyboard 7, the remaining operating time Tr is displayed by display means 10 at least one timer. Said at least one timer is thus parameterized and counting means can automatically cut off the power supply of one or more heating means 2 after the flow of said duration set.

Le procédé de commande comprend une étape E7 d'arrêt dudit au moins un moyen de chauffage 2 si la durée de fonctionnement écoulée Te dudit au moins un chauffage 2 est supérieure ou égale à la durée de cuisson totale souhaitée Tf.The control method comprises a step E7 of stopping said at least one heating means 2 if the elapsed operating time Te of said at least one heating 2 is greater than or equal to the desired total cooking time Tf.

De cette manière, les aliments cuits par l'appareil de cuisson 1 ne peuvent être cuits davantage puisque ledit au moins un moyen de chauffage 2 est arrêté et tout risque de dégradation de l'appareil de cuisson 1 est empêché.In this way, the food cooked by the cooking apparatus 1 can not be further cooked since said at least one heating means 2 is stopped and any risk of degradation of the cooking appliance 1 is prevented.

Si la durée de fonctionnement écoulée Te dudit au moins un chauffage 2 est supérieure ou égale à la durée de cuisson totale souhaitée Tf, l'utilisateur peut arrêter l'appareil de cuisson 1 en appuyant par exemple sur une touche d'allumage et/ou d'extinction 8 d'un ou des moyens de chauffage 2.If the elapsed operating time Te of said at least one heating 2 is greater than or equal to the desired total cooking time Tf, the user can stop the cooking appliance 1 by pressing for example an ignition key and / or extinguishing 8 of one or more heating means 2.

L'acquisition d'une durée de fonctionnement de mise en fonctionnement dudit au moins un moyen de chauffage 2 nécessite la sélection d'un foyer de cuisson 6 par l'utilisateur à l'aide d'une touche de commande.The acquisition of a running time of operation of said at least one heating means 2 requires the selection of a cooking zone 6 by the user with the aid of a control key.

De cette manière, l'affichage de la durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage 2 peut être exécuté dès qu'une commande est acquise lorsque l'utilisateur appuie sur au moins une touche de commande 9 adaptée à commander des moyens de commande de l'appareil de cuisson 1, tel que par exemple un microcontrôleur, et à commander l'affichage de la durée de fonctionnement écoulée Te dudit au moins un moyen de chauffage 2.In this way, the display of the elapsed operating time Te of said at least one heating means 2 can be executed as soon as a command is acquired when the user presses at least one control key 9 adapted to control means. controlling the cooking apparatus 1, such as for example a microcontroller, and controlling the display of the elapsed operating time Te of said at least one heating means 2.

Une telle commande acquise par les moyens de commande de l'appareil de cuisson 1 permet d'afficher sur les moyens d'affichage 10 la durée de fonctionnement écoulée Te depuis la dernière modification d'au moins un paramètre de fonctionnement, tel que la puissance, dudit au moins un moyen de chauffage 2 du foyer de cuisson 6 sélectionné préalablement.Such control acquired by the control means of the cooking apparatus 1 makes it possible to display on the display means 10 the elapsed operating time Te since the last modification of at least one operating parameter, such as the power of said at least one heating means 2 of the previously selected cooking chamber 6.
