L'invention concerne un appareil de cuisson comprenant une enceinte de cuisson comportant au moins un dispositif de dorage à résistance chauffante et un dispositif de génération d'énergie micro-ondes, un circuit d'alimentation du dispositif de dorage à résistance chauffante et du dispositif d'énergie micro-ondes et un tableau de commande qui comporte des moyens de sélection permettant de saisir des familles d'aliments prédéfinies, des moyens d'entrée d'informations d'une durée de consigne T d'une phase de cuisson d'une famille d'aliments, des moyens d'affichage du temps d'au moins la durée de consigne T, et des moyens de commande pour déclencher le déroulement de ladite phase de cuisson, les moyens de sélection, les moyens d'entrée d'information, les moyens d'affichage et les moyens de commande étant reliés à des moyens de traitement d'information qui comprennent, entre autres, des moyens de mémorisation d'au moins la durée de consigne T et des moyens d'annulation, d'une part, de ladite durée de consigne T et, et d'autre part, de l'alimentation du circuit d'alimentation.The invention relates to a cooking appliance. comprising a cooking chamber comprising at least one heating resistance browning device and a microwave energy generation device a feed circuit of the gilding device to heating element and microwave energy device and a control panel which includes means selection to enter food families predefined means for entering information of a setpoint duration T of a family cooking phase food, means for displaying the time of at least the setpoint duration T, and control means for trigger the progress of said cooking phase, the means of selection, means of information entry, the display means and the control means being linked to information processing means which include, among other things, storage means at least the setpoint duration T and means on the one hand, for canceling said setpoint duration T and, on the other hand, the circuit supply Power.
Dans les appareils de cuisson tels que les fours fabriqués actuellement par la Demanderesse, lorsqu'une phase de cuisson a été déclenchée, il n'est pas possible d'interrompre ladite phase de cuisson sans ouvrir la porte de l'enceinte de cuisson. En effet, l'ouverture de ladite porte entraíne l'actionnement d'un interrupteur qui effectue une remise à zéro des moyens de traitement d'informations et efface ainsi toute la phase de cuisson en cours. In cooking appliances such as ovens currently manufactured by the Applicant, when a cooking phase has been triggered, it is not possible to interrupt said cooking phase without opening the door of the cooking chamber. Indeed, the opening of said door causes the actuation of a switch which performs a reset of the processing means information and thus erases the entire cooking phase In progress.
Dans d'autres fours connus, les tableaux de commande desdits fours comportent des touches spécialisées permettant l'annulation d'une phase de cuisson pendant son déroulement. Ces touches augmentent la complexité, d'une part, des tableaux de commande et, d'autre part, de la construction desdits fours.In other known ovens, the tables of control of said ovens have keys specialized allowing the cancellation of a phase of cooking during its progress. These keys increase the complexity, on the one hand, of the control panels and, on the other hand, the construction of said ovens.
Le but de l'invention est de remédier aux inconvénients précités et de permettre une annulation simple et rapide d'une phase de cuisson lors de son déroulement.The object of the invention is to remedy the aforementioned drawbacks and allow cancellation simple and quick cooking phase during unwinding.
Selon l'invention, les moyens de traitement d'information comportent des moyens de commutation entre les moyens d'annulation et les moyens de sélection pour que, lors de l'actionnement des moyens de sélection pendant le déroulement d'une phase de cuisson, les moyens de sélection activent les moyens d'annulation.According to the invention, the processing means include means for switching between the cancellation means and the selection means for that upon actuation of the selection means during the course of a cooking phase, the means selection activates the cancellation means.
Grâce à l'appareil de cuisson selon l'invention, on réduit le nombre de pièces et donc l'encombrement du tableau de commande des fours. Ainsi le temps et le coût de fabrication d'un tel four sont considérablement diminués. D'autre part, du fait de l'utilisation d'une même touche pour effectuer deux fonctions différentes, on améliore la convivialité d'utilisation d'un tel four. En outre, on augmente la sécurité de fonctionnement de ces fours en interdisant le fonctionnement de la phase de cuisson initiale alors que l'utilisateur a modifié les moyens de sélection soit par mégarde, soit volontairement.Thanks to the cooking appliance according to the invention, reduces the number of parts and therefore the size of the oven control panel. So time and cost of manufacturing such an oven are considerably reduced. On the other hand, due to the use of a same key to perform two different functions, we improves the user-friendliness of such an oven. In in addition, the operational safety of these furnaces by prohibiting the operation of the initial cooking while the user has changed the means of selection either by mistake or voluntarily.

deuxième temps, redéclencher une nouvelle phase de
cuisson en actionnant les moyens de commande 11. La durée
D de la phase de suspension est choisie par le fabricant
et présente une valeur de l'ordre de quatre minutes. A la
fin de la durée de la phase de suspension D, si aucun
actionnement n'a été effectué soit sur les moyens
d'entrée d'information 9, soit sur les moyens de
