Description

La présente invention concerne un procédé de commande d'un four de cuisson à micro-ondes.The present invention relates to a method of controlling a microwave cooking oven.

Elle concerne également un four de cuisson à micro-ondes adapté à mettre en oeuvre le procédé de commande conforme à l'invention.It also relates to a microwave oven adapted to implement the control method according to the invention.

De manière générale, la présente invention concerne la commande de cycles de chauffage mis en oeuvre dans une enceinte de chauffage d'un four de cuisson à micro-ondes et l'affichage de données sur un afficheur permettant à l'utilisateur de sélectionner des paramètres de chauffage d'un ou plusieurs aliments placés dans ladite enceinte de chauffage.In general, the present invention relates to the control of heating cycles implemented in a heating chamber of a microwave oven and the display of data on a display allowing the user to select parameters. heating one or more foods placed in said heating chamber.

On connaît déjà des fours de cuisson à micro-ondes comprenant des organes de commande d'un cycle de chauffage mis en oeuvre dans une enceinte de cuisson et des éléments d'affichage des paramètres à sélectionner ou sélectionnés en fonction du cycle de chauffage à mettre en oeuvre.Microwave cooking ovens are already known comprising control members of a heating cycle implemented in a cooking chamber and elements for displaying the parameters to be selected or selected as a function of the heating cycle to be put in place. implemented.

Cependant, ces fours de cuisson à micro-ondes présentent l'inconvénient d'avoir un panneau de commande complexe et peu facile d'utilisation engendrant la non compréhension des utilisateurs du comment programmer de manière optimale un four de cuisson à micro-ondes. Ce panneau de commande est constitué d'un bouton de commande unique ou d'une multitude de boutons de commande et d'un afficheur comprenant des menus de sélection de paramètres complexes et en quantité importante.However, these microwave ovens have the disadvantage of having a complex control panel and not very easy to use generating the lack of understanding of users how to optimally program a microwave oven. This control panel consists of a single control button or a multitude of control buttons and a display comprising menus for selecting complex parameters and in large quantities.

Par conséquent, l'utilisateur utilise très fréquemment les mêmes paramètres de chauffage d'un ou plusieurs aliments sans les modifier en fonction du type d'aliment et de leur poids. Bien souvent, l'utilisateur sélectionne la puissance maximale délivrée par le four de cuisson à micro-ondes et fait varier la durée de chauffage en fonction de son besoin.Consequently, the user very frequently uses the same heating parameters of one or more foods without modifying them according to the type of food and their weight. Often, the user selects the maximum power delivered by the microwave oven and varies the heating time according to his need.

Une telle utilisation d'un four de cuisson à micro-ondes ne permet pas d'obtenir des résultats satisfaisants sur la température du ou des aliments et d'éviter la détérioration de la qualité des aliments à consommer.Such use of a microwave oven does not provide satisfactory results on the temperature of the food or foods and avoid deterioration in the quality of food to consume.

Cette utilisation d'un four de cuisson à micro-ondes provoque chez l'utilisateur le sentiment que cet appareil à des capacités limitées et ne sert à uniquement à faire chauffer rapidement des aliments, et tout particulièrement des boissons.This use of a microwave oven causes the user to feel that this device has limited capacity and serves only to heat quickly food, especially drinks.

Par ailleurs, l'utilisateur programme un cycle de chauffage à chaque utilisation du four de cuisson à micro-ondes sans prendre en considération les paramètres du cycle de chauffage précédemment exécuté.Furthermore, the user programs a heating cycle with each use of the microwave oven without taking into consideration the parameters of the previously executed heating cycle.

On connaît également le document JP 60 008 626 A qui décrit un procédé comprenant les étapes de mémorisation des paramètres, de puissance de chauffage et de temps de chauffage, d'une séquence de chauffage exécutée, d'affichage de ces paramètres mémorisés préalablement et d'exécution d'une nouvelle séquence de chauffage avec les paramètres mémorisés.The document is also known JP 60,008,626 A which describes a method comprising the steps of storing the parameters, the heating power and the heating time, a heating sequence executed, displaying these previously stored parameters and executing a new sequence of heating with the stored parameters.

On connaît également le document US 5 906 765 A qui décrit un four à micro-ondes permettant de corriger une durée de cuisson saisie en fonction d'une comparaison d'un niveau de puissance saisi avec un niveau de puissance prédéterminé.The document is also known US 5,906,765 A which describes a microwave oven for correcting an entered cooking time based on a comparison of a power level entered with a predetermined power level.

La présente invention a pour but de résoudre les inconvénients précités et de proposer un four de cuisson à micro-ondes et un procédé de commande d'un four de cuisson à micro-ondes permettant d'améliorer l'ergonomie d'utilisation, de simplifier les actions à réaliser par l'utilisateur pour commander ledit four de cuisson à micro-ondes, et d'affiner simplement le résultat de chauffage des aliments en fin de cycle de chauffage.The present invention aims to solve the aforementioned drawbacks and to provide a microwave oven and a control method of a microwave oven for improving the ergonomics of use, to simplify the actions to be performed by the user to control said microwave oven, and to simply refine the heating result of food at the end of the heating cycle.

A cet égard, la présente invention vise, selon un premier aspect, un procédé de commande d'un four de cuisson à micro-ondes comprenant une unité de commande, une enceinte de chauffage, des moyens de chauffage, un panneau de commande, ledit panneau de commande comprenant au moins un afficheur et des moyens de sélection d'un cycle de chauffage.In this regard, the present invention aims, in a first aspect, a method of controlling a microwave oven comprising a control unit, a heating chamber, heating means, a control panel, said control panel comprising at least one display and means for selecting a heating cycle.

Selon l'invention, le procédé comprend les étapes suivantes :

  • exécution d'un cycle de chauffage par ledit four de cuisson à micro-ondes ;
  • proposition de trois modes de commande par ladite unité de commande suite à ladite étape d'exécution d'un cycle de chauffage ;
  • où les trois modes de commande sont les suivants :
    • o répétition dudit cycle de chauffage précédemment exécuté de sorte à répéter un même cycle de chauffage avec des paramètres de chauffage identiques en sélectionnant le mode de commande de répétition dudit cycle de chauffage précédemment exécuté, où les paramètres de chauffage dudit cycle de chauffage précédemment exécuté sont mémorisés automatiquement et pouvant être mis en oeuvre plusieurs fois à la suite ;
    • o prolongation dudit cycle de chauffage précédemment exécuté ; et
    • o arrêt dudit four de cuisson à micro-ondes ;
  • acquisition d'un signal d'entrée correspondant à la sélection d'un des trois modes de commande proposés suite à ladite étape d'exécution d'un cycle de chauffage ; et
  • exécution dudit mode de commande sélectionné.
According to the invention, the method comprises the following steps:
  • performing a heating cycle by said microwave cooking oven;
  • proposing three control modes by said control unit following said step of executing a heating cycle;
  • where the three control modes are:
    • repeating said heating cycle previously executed so as to repeat the same heating cycle with identical heating parameters by selecting the repeat control mode of said previously executed heating cycle, wherein the heating parameters of said previously executed heating cycle are stored automatically and can be implemented several times in succession;
    • o extension of said previously executed heating cycle; and
    • stopping said microwave oven;
  • acquisition of an input signal corresponding to the selection of one of the three proposed control modes following said step of executing a heating cycle; and
  • execution of said selected control mode.

Ainsi, un tel procédé de commande permet d'accéder simplement à trois modes de commande suite à l'étape d'exécution d'un cycle de chauffage et de sélectionner un de ceux-ci tout en conservant les paramètres sélectionnés préalablement de sorte à éviter de sélectionner de nouveau ces paramètres.Thus, such a control method makes it possible to simply access three control modes following the step of executing a heating cycle and to select one of these while keeping the previously selected parameters so as to avoid to select these settings again.

Le premier mode de commande est la répétition du cycle de chauffage précédemment exécuté de sorte à faciliter l'exécution successive d'un même cycle de chauffage sans avoir à sélectionner une multitude de menus ou à sélectionner les mêmes paramètres pour chaque cycle de chauffage. Le cycle de chauffage précédemment exécuté peut ainsi être répété avec les mêmes paramètres de chauffage sélectionnés pour ledit cycle de chauffage précédent.The first control mode is the repetition of the heating cycle previously executed so as to facilitate the successive execution of the same heating cycle without having to select a multitude of menus or to select the same parameters for each heating cycle. The previously executed heating cycle can thus be repeated with the same heating parameters selected for said previous heating cycle.

Le deuxième mode de commande est la prolongation du cycle de chauffage précédemment exécuté de sorte à rallonger la durée de chauffage d'aliments sans avoir à sélectionner de nouveau tous les paramètres de chauffage et à régler une durée de chauffe supplémentaire. Le cycle de chauffage précédemment exécuté peut ainsi être prolongé simplement en fonction des paramètres de chauffage sélectionnés pour ledit cycle de chauffage précédent.The second control mode is the prolongation of the previously executed heating cycle so as to lengthen the food heating time without having to re-select all the heating parameters and to set an additional heating time. The previously executed heating cycle can thus be extended simply according to the heating parameters selected for said previous heating cycle.

Le troisième mode de commande est l'arrêt du four de cuisson à micro-ondes suite à l'exécution d'un cycle de chauffage lorsque l'utilisateur est satisfait du résultat obtenu à la fin du cycle de chauffage mis en oeuvre.The third control mode is the stopping of the microwave cooking oven following the execution of a heating cycle when the user is satisfied with the result obtained at the end of the heating cycle implemented.

Le procédé comprend une étape d'enregistrement automatique des paramètres des cycles de chauffage exécutés.The method comprises a step of automatically recording the parameters of the heating cycles executed.

Ainsi, le procédé de commande conforme à l'invention permet d'éviter que l'utilisateur sélectionne des paramètres d'un cycle de chauffage par rapport à des données dont il se souvient concernant par exemple la puissance de chauffe et le temps de chauffe pour différents aliments.Thus, the control method according to the invention makes it possible to prevent the user from selecting parameters of a heating cycle with respect to data which he remembers concerning, for example, the heating power and the heating time for different foods.

Le procédé de commande permet ainsi de sélectionner manuellement des cycles de chauffage qui sont enregistrés par le four de cuisson à micro-ondes de sorte à pouvoir réutiliser ces mêmes cycles de chauffage facilement et rapidement quand l'utilisateur le souhaite sans que celui-ci ait à faire appel à sa mémoire.The control method thus makes it possible to manually select heating cycles which are recorded by the microwave cooking oven so that these same heating cycles can be reused easily and quickly when the user wishes it without the latter having to appeal to his memory.

L'exécution d'un cycle de chauffage mémorisé reprend ainsi les paramètres dudit cycle de chauffage précédemment exécuté.The execution of a memorized heating cycle thus takes over the parameters of the previously executed heating cycle.

Dans le cas d'un cycle de chauffage précédent ayant fait l'objet d'une ou plusieurs prolongations et étant mémorisé par une unité de commande du four de cuisson à micro-ondes, la durée du cycle de chauffage précédemment exécuté et la ou les durées de la ou des prolongations sont cumulées de sorte que le cycle de chauffage mémorisé et sélectionné soit mis en oeuvre sur la durée totale dudit cycle de chauffage mémorisé.In the case of a previous heating cycle which has been extended for one or more periods and is stored by a control unit of the microwave oven, the duration of the heating cycle previously performed and the one or more durations of the extension (s) are accumulated so that the memorized and selected heating cycle is implemented over the total duration of said stored heating cycle.

Selon une autre caractéristique préférée de l'invention, ledit procédé comprend également une étape de tri des cycles de chauffage les plus utilisés comportant les mêmes paramètres.According to another preferred feature of the invention, said method also comprises a step of sorting the most used heating cycles comprising the same parameters.

Ainsi, l'unité de commande du four de cuisson à micro-ondes permet de trier automatiquement les cycles de chauffage les plus utilisés de sorte à faciliter l'accès aux cycles de chauffage préférés par un utilisateur.Thus, the control unit of the microwave cooking oven can automatically sort the most used heating cycles so as to facilitate access to user preferred heating cycles.

Selon un second aspect, la présente invention concerne un four de cuisson à micro-ondes, comprenant une unité de commande, une enceinte de chauffage, des moyens de chauffage, un panneau de commande, ledit panneau de commande comprenant au moins un afficheur et des moyens de sélection d'un cycle de chauffage, et ladite unité de commande comprenant au moins un microprocesseur.According to a second aspect, the present invention relates to a microwave oven, comprising a control unit, a heating chamber, heating means, a control panel, said control panel comprising at least one display and means for selecting a heating cycle, and said control unit comprising at least one microprocessor.

Selon l'invention, ledit four de cuisson à micro-ondes comprend un algorithme de traitement adapté à mettre en oeuvre le procédé de commande conforme à l'invention.According to the invention, said microwave cooking oven comprises a processing algorithm adapted to implement the control method according to the invention.

Ce four de cuisson à micro-ondes présente des avantages analogues à ceux décrits précédemment en référence au procédé de commande selon l'invention.This microwave oven has advantages similar to those described above with reference to the control method according to the invention.

Le procédé de commande d'un four de cuisson à micro-ondes comprend les étapes suivantes :

  • exécution E10 d'un cycle de chauffage par ledit four de cuisson à micro-ondes ;
  • proposition E20 de trois modes de commande E21, E22, E23 par ladite unité de commande suite à ladite étape d'exécution E10 d'un cycle de chauffage ;
  • où les trois modes de commande E21, E22, E23 sont les suivants :
    • o répétition E21 dudit cycle de chauffage précédemment exécuté ;
    • o prolongation E23 dudit cycle de chauffage précédemment exécuté ; et
    • o arrêt E22 dudit four de cuisson à micro-ondes ;
  • acquisition E24 d'un signal d'entrée correspondant à la sélection d'un des trois modes de commande E21, E22, E23 proposés suite à ladite étape d'exécution E10 d'un cycle de chauffage ; et
  • exécution E211, E221, E231 dudit mode de commande E21, E22, E23 sélectionné.
The method of controlling a microwave oven includes the following steps :
  • execution E10 of a heating cycle by said microwave cooking oven;
  • proposition E20 of three control modes E21, E22, E23 by said control unit following said execution step E10 of a heating cycle;
  • where the three control modes E21, E22, E23 are as follows:
    • o repetition E21 of said previously executed heating cycle;
    • o extension E23 of said previously executed heating cycle; and
    • stopping E22 of said microwave cooking oven;
  • acquisition E24 of an input signal corresponding to the selection of one of the three control modes E21, E22, E23 proposed following said execution step E10 of a heating cycle; and
  • execution E211, E221, E231 of said control mode E21, E22, E23 selected.

Ainsi, un tel procédé de commande permet d'accéder simplement à trois modes de commande E21, E22, E23 suite à l'étape d'exécution E10 d'un cycle de chauffage et de sélectionner un de ceux-ci tout en conservant les paramètres sélectionnés préalablement de sorte à éviter de sélectionner de nouveau ces paramètres.Thus, such a control method makes it possible to simply access three control modes E21, E22, E23 following the execution step E10 of a heating cycle and to select one of these while keeping the parameters previously selected so as to avoid selecting these parameters again.

Le premier mode de commande E21 est la répétition du cycle de chauffage précédemment exécuté de sorte à faciliter l'exécution successive d'un même cycle de chauffage sans avoir à sélectionner une multitude de menus ou à sélectionner les mêmes paramètres pour chaque cycle de chauffage. Le cycle de chauffage précédemment exécuté peut ainsi être répété avec les mêmes paramètres de chauffage sélectionnés pour ledit cycle de chauffage précédent.The first control mode E21 is the repetition of the previously executed heating cycle so as to facilitate the successive execution of the same heating cycle without having to select a multitude of menus or to select the same parameters for each heating cycle. The previously executed heating cycle can thus be repeated with the same heating parameters selected for said previous heating cycle.

Le mode de commande de répétition E21 du cycle de chauffage précédemment exécuté peut être mis en oeuvre simplement par l'activation d'un moyen de sélection 3, 4, 5, et en particulier par l'appui sur une touche du moyen de sélection 3.The repeat control mode E21 of the previously executed heating cycle can be implemented simply by activating a selection means 3, 4, 5, and in particular by pressing a key of the selection means 3. .

De cette manière, l'utilisateur peut répéter un même cycle de chauffage avec des paramètres de chauffage identiques, par exemple dans le cas du chauffage de plats identiques.In this way, the user can repeat the same heating cycle with identical heating parameters, for example in the case of heating identical dishes.

Dans un mode de réalisation de l'invention, le four de cuisson à micro-ondes peut être adapté pour chauffer une portion correspondant à la taille d'une assiette. En sélectionnant le mode de commande de répétition E21 du cycle de chauffage précédemment exécuté, plusieurs assiettes contenant les mêmes aliments peuvent être chauffés successivement dans l'enceinte de chauffage sans avoir à régler les paramètres de chauffage du four de cuisson à micro-ondes pour chacune des assiettes.In one embodiment of the invention, the microwave cooking oven may be adapted to heat a portion corresponding to the size of a plate. By selecting the repeat control mode E21 of the heating cycle previously performed, several plates containing the same food can be heated successively in the heating chamber without having to adjust the parameters. heating the microwave oven for each of the plates.

Les paramètres de chauffage des aliments de la première assiette placée dans l'enceinte de chauffage du four de cuisson à micro-ondes peuvent ainsi être mémorisés et mis en oeuvre plusieurs fois à la suite.The food heating parameters of the first plate placed in the heating chamber of the microwave oven can thus be memorized and implemented several times in succession.

Ces paramètres de chauffage des aliments de la première assiette peuvent comprendre les paramètres de réglage initiaux ainsi que les paramètres correspondants à un ou plusieurs modes de commande de prolongation E23. La durée du cycle de chauffage mis en oeuvre lors de la sélection d'un mode de commande de répétition E21 peut ainsi être égale à la durée d'un cycle de chauffage précédemment exécuté cumulée avec la ou les durées d'un ou plusieurs modes de prolongation dudit cycle de chauffage précédemment exécuté.These food heating parameters of the first plate may include the initial setting parameters as well as the parameters corresponding to one or more extension control modes E23. The duration of the heating cycle implemented during the selection of a repeat control mode E21 may thus be equal to the duration of a previously executed cumulative heating cycle with the duration or times of one or more modes of heating. prolonging said previously executed heating cycle.

Le deuxième mode de commande E23 est la prolongation du cycle de chauffage précédemment exécuté de sorte à rallonger la durée de chauffage d'aliments sans avoir à sélectionner de nouveau tous les paramètres de chauffage et à régler une durée de chauffe supplémentaire. Le cycle de chauffage précédemment exécuté peut ainsi être prolongé simplement en fonction des paramètres de chauffage sélectionnés pour ledit cycle de chauffage précédent.The second control mode E23 is the prolongation of the heating cycle previously performed so as to extend the heating time of food without having to re-select all the heating parameters and to set an additional heating time. The previously executed heating cycle can thus be extended simply according to the heating parameters selected for said previous heating cycle.

Le mode de commande de prolongation E23 du cycle de chauffage précédemment exécuté peut être mis en oeuvre simplement par l'activation d'un moyen de sélection 3, 4, 5, et en particulier par l'appui sur une touche du moyen de sélection 5.The extension control mode E23 of the previously executed heating cycle can be implemented simply by activating a selection means 3, 4, 5, and in particular by pressing a key of the selection means 5. .

De cette manière, l'utilisateur peut prolonger un cycle de chauffage précédemment exécuté à partir des paramètres de chauffage initiaux, par exemple dans le cas où le ou les aliments ne sont pas assez chauds.In this way, the user can extend a heating cycle previously performed from the initial heating parameters, for example in the case where the food or foods are not hot enough.

L'unité de commande du four de commande peut également être adaptée à préconiser une durée de prolongation d'un cycle de chauffage précédemment exécuté en fonction des paramètres de chauffage initiaux.The control unit of the control furnace may also be adapted to recommend an extension time of a previously executed heating cycle according to the initial heating parameters.

Le troisième mode de commande E22 est l'arrêt du four de cuisson à micro-ondes suite à l'exécution d'un cycle de chauffage lorsque l'utilisateur est satisfait du résultat obtenu à la fin du cycle de chauffage mis en oeuvre.The third control mode E22 is the stopping of the microwave cooking oven following the execution of a heating cycle when the user is satisfied with the result obtained at the end of the heating cycle implemented.

Le mode de commande d'arrêt E22 du four de cuisson à micro-ondes peut être mis en oeuvre simplement par l'activation d'un moyen de sélection 3, 4, 5, et en particulier par l'appui sur une touche du moyen de sélection 4.The stop control mode E22 of the microwave cooking oven can be implemented simply by the activation of a selection means 3, 4, 5, and in particular by the pressing of a key of the means. Selection 4.

De cette manière, l'utilisateur peut arrêter le four de cuisson à micro-ondes, par exemple dans le cas où le ou les aliments sont suffisamment chauds.In this way, the user can stop the microwave oven, for example in the case where the food or foods are hot enough.

Le cycle de chauffage précédemment exécuté par l'unité de commande du four de cuisson à micro-ondes peut aussi bien être un cycle de chauffage qu'un cycle de décongélation.The heating cycle previously performed by the control unit of the microwave cooking oven may as well be a heating cycle as a defrosting cycle.

L'étape d'exécution E10 d'un cycle de chauffage par le four de cuisson à micro-ondes peut être précédée d'une étape de sélection E0 manuelle ou automatisée des paramètres de chauffage à utiliser pour ledit cycle de chauffage à exécuter.The execution step E10 of a heating cycle by the microwave cooking oven may be preceded by a manual or automated selection step E0 of the heating parameters to be used for said heating cycle to be performed.

Dans le cas d'une sélection manuelle des paramètres de chauffage à utiliser pour le cycle de chauffage à exécuter, l'utilisateur utilise les moyens de sélection 3, 4, 5. Ces moyens de sélection 3, 4, 5 peuvent être par exemple des boutons, des touches sensitives.In the case of a manual selection of the heating parameters to be used for the heating cycle to be performed, the user uses the selection means 3, 4, 5. These selection means 3, 4, 5 may be, for example, buttons, sensitive keys.

Dans le cas d'une sélection automatisée des paramètres de chauffage à utiliser pour le cycle de chauffage à exécuter, un ou plusieurs capteurs reliées à l'unité de commande peuvent être mis en oeuvre de sorte à déterminer les paramètres liés aux aliments introduits dans l'enceinte de chauffage et au chauffage de ceux-ci.In the case of an automated selection of the heating parameters to be used for the heating cycle to be performed, one or more sensors connected to the control unit may be implemented so as to determine the parameters related to the food introduced into the room. heating chamber and heating thereof.

Bien entendu, dans le cas d'une sélection automatisée des paramètres de chauffage à utiliser pour le cycle de chauffage à exécuter, l'utilisateur peut utiliser les moyens de sélection 3, 4, 5.Of course, in the case of an automated selection of the heating parameters to be used for the heating cycle to be performed, the user can use the selection means 3, 4, 5.

Dans un mode de réalisation de l'invention, l'étape de proposition E20 de trois modes de commande E21, E22, E23 par l'unité de commande est mise en oeuvre suite à une étape d'ouverture d'une porte obturant l'enceinte de chauffage.In one embodiment of the invention, the proposal step E20 of three control modes E21, E22, E23 by the control unit is implemented following a step of opening a door closing the door. heating enclosure.

Ainsi, ledit au moins un afficheur du panneau de commande du four de cuisson à micro-ondes présente les trois modes de commande E21, E22, E23 suite à l'ouverture de la porte obturant l'enceinte de cuisson de sorte que l'utilisateur puisse contrôler le chauffage des aliments placés dans l'enceinte de chauffage avant la sélection d'un de ces trois modes de commande E21, E22, E23, lorsqu'un cycle de chauffage a été précédemment exécuté.Thus, said at least one display of the control panel of the microwave oven has the three control modes E21, E22, E23 following the opening of the door closing the cooking chamber so that the user can control the heating of the food placed in the heating chamber before selecting one of these three control modes E21, E22, E23, when a heating cycle has been previously executed.

Préférentiellement, l'étape de proposition E20 de trois modes de commande E21, E22, E23 par l'unité de commande est présentée suite à chaque étape d'exécution E211, E231 d'un mode de répétition E21 ou d'un mode de prolongation E23.Preferably, the proposal step E20 of three control modes E21, E22, E23 by the control unit is presented following each execution step E211, E231 of a repeat mode E21 or an extension mode E23.

Ainsi, l'utilisateur a la possibilité de manière simple et aisée soit de prolonger le cycle de chauffage exécuté précédemment jusqu'à l'obtention du résultat de chauffage souhaité soit de répéter le cycle de chauffage précédemment exécuté le nombre de fois qu'il souhaite.Thus, the user has the possibility in a simple and easy way either to extend the previously executed heating cycle until the desired heating result is obtained, or to repeat the heating cycle previously executed the number of times it wishes .

Une étape de maintien au chaud E25 est mise en oeuvre à partir d'une durée prédéterminée D écoulée suite à ladite étape de proposition E20 de trois modes de commande E21, E22, E23.A warming step E25 is carried out starting from a predetermined duration D elapsed following said proposal step E20 of three control modes E21, E22, E23.

Ainsi, le ou les aliments chauffés lors du cycle de chauffage précédemment exécuté ne se refroidissent pas et l'utilisateur peut les consommer dès leur sortie de l'enceinte de cuisson du four de cuisson à micro-ondes.Thus, the food or foods heated during the heating cycle previously performed do not cool and the user can consume them as they exit the cooking chamber of the microwave oven.

La durée prédéterminée D s'écoulant entre l'étape de proposition E20 de trois modes de commande E21, E22, E23 et le déclenchement de l'étape de maintien au chaud E25 peut être comprise entre 15 secondes et 2 minutes, et préférentiellement de l'ordre de une minute.The predetermined duration D flowing between the proposition step E20 of three control modes E21, E22, E23 and the triggering of the warm-up step E25 can be between 15 seconds and 2 minutes, and preferably of the order of one minute.

Bien entendu, la valeur de la durée prédéterminée D s'écoulant entre l'étape de proposition E20 de trois modes de commande E21, E22, E23 et le déclenchement de l'étape de maintien au chaud E25 n'est nullement limitative et peut être différente.Of course, the value of the predetermined duration D flowing between the proposal step E20 of three control modes E21, E22, E23 and the triggering of the warming step E25 is in no way limiting and can be different.

L'étape de maintien au chaud E25 est mise en oeuvre pendant une durée prédéterminée T.The warming step E25 is carried out for a predetermined duration T.

Si aucun signal d'entrée n'est acquis au cours de la durée prédéterminée T de l'étape de maintien au chaud E25, l'unité de commande du four de cuisson à micro-ondes affiche un menu principal E26 sur ledit au moins un afficheur 2 du panneau de commande 1.If no input signal is acquired during the predetermined duration T of the warming step E25, the control unit of the microwave cooking oven displays a main menu E26 on said at least one display 2 on the control panel 1.

Si un signal d'entrée est acquis au cours de la durée prédéterminée T de l'étape de maintien au chaud E25, l'unité de commande du four de cuisson à micro-ondes retourne à l'étape de proposition E20 de trois modes de commande E21, E22, E23 de sorte que l'utilisateur puisse choisir le mode de commande E21, E22, E23 qu'il souhaite suite à l'exécution E10 du cycle de chauffage précédent.If an input signal is acquired during the predetermined duration T of the warming step E25, the control unit of the microwave cooking oven returns to the proposal step E20 of three modes of control E21, E22, E23 so that the user can choose the control mode E21, E22, E23 he wants following the execution E10 of the previous heating cycle.

L'acquisition d'un signal d'entrée au cours de la durée prédéterminée T de l'étape de maintien au chaud E25 peut être obtenue, notamment, soit par l'ouverture d'une porte de l'enceinte de cuisson soit par l'activation d'un des moyens de sélection 3, 4, 5 du panneau de commande 1.The acquisition of an input signal during the predetermined duration T of the warming step E25 can be obtained, in particular, either by opening a door of the cooking chamber or by activation of one of the selection means 3, 4, 5 of the control panel 1.

La durée prédéterminée T de l'étape de maintien au chaud E25 peut être comprise entre 2 minutes et 20 minutes, et préférentiellement de l'ordre de 15 minutes.The predetermined duration T of the warming step E25 may be between 2 minutes and 20 minutes, and preferably of the order of 15 minutes.

Bien entendu, la valeur de la durée prédéterminée T de l'étape de maintien au chaud E25 n'est nullement limitative et peut être différente.Of course, the value of the predetermined duration T of the warming step E25 is in no way limiting and may be different.

Dans un autre mode de réalisation de l'invention, l'unité de commande du four de cuisson à micro-ondes affiche un menu principal 26 sur ledit au moins un afficheur 2 du panneau de commande si aucun signal d'entrée n'est acquis au cours d'une durée prédéterminée P suite à ladite étape de proposition E20 de trois modes de commande E21, E22, E23, ou encore l'unité de commande du four de cuisson à micro-ondes passe dans un mode à basse consommation d'énergie si aucun signal d'entrée n'est acquis au cours de la durée prédéterminée P suite à ladite étape de proposition E20 de trois modes de commande E21, E22, E23.In another embodiment of the invention, the control unit of the microwave cooking oven displays a main menu 26 on said at least one display 2 of the control panel if no input signal is acquired. during a predetermined period P following said proposal step E20 of three control modes E21, E22, E23, or the control unit of the microwave oven goes into a low power consumption mode. energy if no input signal is acquired during the predetermined duration P following said proposal step E20 of three control modes E21, E22, E23.

Bien entendu, la valeur de la durée prédéterminée P de retour au menu principal 26 ou de passage dans un mode à basse consommation d'énergie n'est nullement limitative et peut être différente.Of course, the value of the predetermined duration P returning to the main menu 26 or switching to a low-energy mode is in no way limiting and may be different.

L'étape d'acquisition E24 d'un signal d'entrée correspondant à la sélection d'un des trois modes de commande E21, E22, E23 proposés suite à ladite étape d'exécution E10 d'un cycle de chauffage peut être mise en oeuvre par l'intermédiaire d'un des moyens de sélection 3, 4, 5 du panneau de commande 1.The acquisition step E24 of an input signal corresponding to the selection of one of the three control modes E21, E22, E23 proposed following said execution step E10 of a heating cycle can be implemented. by means of one of the selection means 3, 4, 5 of the control panel 1.

Ici et de manière nullement limitative, le moyen de sélection 3 est adapté à sélectionner le mode de commande de répétition E21 du cycle de chauffage précédemment exécuté, le moyen de sélection 4 est adapté à sélectionner le mode de commande d'arrêt E22 du four de cuisson à micro-ondes, et le moyen de sélection 5 est adapté à sélectionner le mode de commande de prolongation E23 du cycle de chauffage précédemment exécuté.Here and in no way limiting, the selection means 3 is adapted to select the repeat control mode E21 of the heating cycle previously performed, the selection means 4 is adapted to select the stop control mode E22 of the oven of microwave cooking, and the selection means 5 is adapted to select the extension control mode E23 of the previously executed heating cycle.

Suite à l'exécution E221 d'un mode de commande d'arrêt E22 du four de cuisson à micro-ondes ou suite à l'étape de maintien au chaud E25, l'unité de commande affiche un menu principal E26 sur ledit au moins un afficheur 2 du panneau de commande 1.Following the execution E221 of a stop control mode E22 of the microwave cooking oven or following the warming step E25, the control unit displays a main menu E26 on the at least one a display 2 on the control panel 1.

Ainsi, l'utilisateur peut sélectionner un autre cycle de chauffage à partir de paramètres différents du cycle de chauffage précédent. L'unité de commande du four de cuisson à micro-ondes peut également mettre ledit four en mode veille suite à l'écoulement d'une durée prédéterminée à partir de l'instant du retour au menu principal E26.Thus, the user can select another heating cycle from different parameters of the previous heating cycle. The control unit of the microwave cooking oven can also put said oven in standby mode after the lapse of a predetermined time from the moment of return to the main menu E26.

L'exécution E221 du mode de commande d'arrêt E22 du four de cuisson à micro-ondes permet de retourner au menu principal E26 de l'afficheur 2.Execution E221 of the stop control mode E22 of the microwave oven returns to the main menu E26 of the display 2.

L'étape de proposition E20 de trois modes de commande E21, E22, E23 par l'unité de commande est réitérée suite à l'exécution E211 d'un mode de commande de répétition E21 du cycle de chauffage précédemment exécuté ou suite à l'exécution E231 d'un mode de commande de prolongation E23 du cycle de chauffage précédemment exécuté.The proposal step E20 of three control modes E21, E22, E23 by the control unit is repeated following the execution E211 of a repeat control mode E21 of the heating cycle previously executed or following the execution E231 of an extension control mode E23 of the previously executed heating cycle.

L'exécution E211 du mode de commande de répétition E21 du cycle de chauffage précédemment exécuté renvoie à l'étape d'exécution E10 de sorte à répéter ledit cycle de chauffage avec les mêmes paramètres de chauffage. Ensuite, l'étape de proposition E20 de trois modes de commande E21, E22, E23 par l'unité de commande est de nouveau mise en oeuvre jusqu'à l'acquisition E24 d'un signal d'entrée du mode de commande d'arrêt E22 du four de cuisson à micro-ondes.The execution E211 of the repeat control mode E21 of the previously executed heating cycle returns to the execution step E10 so as to repeat said heating cycle with the same heating parameters. Then, the proposal step E20 of three control modes E21, E22, E23 by the control unit is again implemented until the acquisition E24 of an input signal of the control mode of stopping E22 of the microwave oven.

L'exécution E211 du mode de commande de répétition E21 du cycle de chauffage précédemment exécuté peut ainsi être mise en oeuvre à plusieurs reprises tant qu'un signal d'entrée du mode de commande d'arrêt E22 du four de cuisson à micro-ondes n'est pas acquis.The execution E211 of the repeat control mode E21 of the previously executed heating cycle can thus be implemented several times as long as an input signal of the stop control mode E22 of the microwave cooking oven. is not acquired.

Une étape de sélection E232 d'une durée de prolongation L du cycle de chauffage précédemment exécuté est mise en oeuvre suite à l'acquisition E24 d'un signal d'entrée correspondant à la sélection du mode de commande E23 de prolongation dudit cycle de chauffage précédemment exécuté.A selection step E232 of an extension duration L of the previously executed heating cycle is carried out following the acquisition E24 of an input signal. corresponding to the selection of the control mode E23 for prolonging said previously executed heating cycle.

L'exécution E231 du mode de commande de prolongation E23 du cycle de chauffage précédemment exécuté permet d'accéder à une étape de sélection E232 d'une durée de prolongation L du cycle de chauffage précédemment exécuté. Lorsque la durée de prolongation L du cycle de chauffage précédemment exécuté est écoulée, l'étape de proposition E20 de trois modes de commande E21, E22, E23 par l'unité de commande est de nouveau mise en oeuvre jusqu'à l'acquisition E24 d'un signal d'entrée du mode de commande d'arrêt E22 du four de cuisson à micro-ondes.The execution E231 of the heating cycle extension control mode E23 previously executed makes it possible to access a selection step E232 with an extension duration L of the previously executed heating cycle. When the extension duration L of the previously executed heating cycle has elapsed, the proposal step E20 of three control modes E21, E22, E23 by the control unit is again implemented until the acquisition E24 an input signal of the stop control mode E22 of the microwave cooking oven.

L'exécution E231 du mode de commande de prolongation E23 du cycle de chauffage précédemment exécuté peut ainsi être mise en oeuvre à plusieurs reprises tant qu'un signal d'entrée du mode de commande d'arrêt E22 du four de cuisson à micro-ondes n'est pas acquis.The execution E231 of the extension cycle control mode E23 of the previously executed heating cycle can thus be implemented several times as long as an input signal of the stop control mode E22 of the microwave cooking oven. is not acquired.

La durée de prolongation L du cycle de chauffage précédemment exécuté peut être réglée par un des moyens de sélection 3, 4, 5, et en particulier le moyen de sélection 5 comprenant deux touches permettant d'augmenter ou de diminuer une durée.The extension time L of the previously executed heating cycle can be set by one of the selection means 3, 4, 5, and in particular the selection means 5 comprising two keys for increasing or decreasing a duration.

Avantageusement, le procédé comprend une étape d'enregistrement automatique des paramètres des cycles de chauffage exécutés.Advantageously, the method comprises a step of automatically recording the parameters of the heating cycles executed.

Ainsi, le procédé de commande conforme à l'invention permet d'éviter que l'utilisateur sélectionne des paramètres d'un cycle de chauffage par rapport à des données dont il se souvient concernant par exemple la puissance de chauffe et le temps de chauffe pour différents aliments.Thus, the control method according to the invention makes it possible to prevent the user from selecting parameters of a heating cycle with respect to data which he remembers concerning, for example, the heating power and the heating time for different foods.

Le procédé de commande permet ainsi de sélectionner manuellement des cycles de chauffage qui sont enregistrés par le four de cuisson à micro-ondes de sorte à pouvoir réutiliser ces mêmes cycles de chauffage facilement et rapidement quand l'utilisateur le souhaite sans que celui-ci ait à faire appel à sa mémoire.The control method thus makes it possible to manually select heating cycles which are recorded by the microwave cooking oven so that these same heating cycles can be reused easily and quickly when the user wishes it without the latter having to appeal to his memory.

La détermination des cycles de chauffage comportant les mêmes paramètres les plus utilisés est mise en oeuvre par l'unité de commande en comparant les cycles de chauffage exécutés et en incrémentant un compteur à chaque fois qu'un cycle de chauffage est exécuté avec les mêmes paramètres de chauffage par rapport à un cycle de chauffage précédemment exécuté.The determination of the heating cycles comprising the same most used parameters is carried out by the control unit by comparing the heating cycles executed and by incrementing a counter each time a heating cycle is executed with the same parameters. of heating compared to a previously executed heating cycle.

Le procédé peut également comprendre une étape de tri des cycles de chauffage les plus utilisés comportant les mêmes paramètres.The method may also include a step of sorting the most used heating cycles having the same parameters.

Ainsi, l'unité de commande du four de cuisson permet de trier automatiquement les cycles de chauffage les plus utilisés de sorte à faciliter l'accès aux cycles de chauffage préférés par un utilisateur.Thus, the control unit of the baking oven can automatically sort the most used heating cycles so as to facilitate access to the heating cycles preferred by a user.

Le procédé comprend une étape d'acquisition d'un signal d'entrée correspondant à la sélection d'un des cycles de chauffage les plus utilisés.The method comprises a step of acquiring an input signal corresponding to the selection of one of the most used heating cycles.

Ainsi, l'utilisateur peut sélectionner rapidement et sans avoir à rechercher fastidieusement dans une mémoire de l'unité de commande un cycle de chauffage fréquemment utilisé.Thus, the user can select quickly and without having to search fastidiously in a memory of the control unit a frequently used heating cycle.

L'utilisateur peut ainsi sélectionner un cycle de chauffage exécuté quotidiennement par un menu d'accès rapide aux cycles de chauffage exécutés fréquemment.The user can thus select a heating cycle executed daily by a quick access menu to the heating cycles executed frequently.
