Domestic microwave oven operating anomaly e.g. no-load operation, detecting method, involves analyzing signal on period, detecting oven`s no-load operation if signal is equal to value, and detecting blocking of dish if signal has profile
The method involves recording a signal of a sensor (12) e.g. ultrasonic sensor, to measure distance between an obstacle and the sensor that is mounted in a lateral wall (13) of a cavity (10) of a domestic microwave oven. The recorded signal is analyzed on a time period. Operating anomaly of the oven...

Abstract | The method involves recording a signal of a sensor (12) e.g. ultrasonic sensor, to measure distance between an obstacle and the sensor that is mounted in a lateral wall (13) of a cavity (10) of a domestic microwave oven. The recorded signal is analyzed on a time period. Operating anomaly of the oven are detected from analysis result. A no-load operation of the oven is detected if the recorded signal is constant and equal to a value corresponding to distance of the sensor to the wall. The blocking of a dish on a rotating plate (11) is detected if the recorded signal has a variable profile.
Un procédé de détection d'une anomalie de fonctionnement d'un four à micro-ondes comprend les étapes suivantes :- enregistrement d'un signal d'un capteur (12) adapté à mesurer une distance entre le capteur (12) et un obstacle, le capteur (12) étant monté dans une paroi (13) de la cavité (10) du four à micro-ondes ;- analyse du signal enregistré sur une période de temps prédéterminée ; et- détection d'une anomalie de fonctionnement à partir du résultat de l'analyse.Utilisation pour détecter le fonctionnement à vide du four à micro-ondes ou le blocage d'un plat sur un plateau tournant (11). |
