Title (EN) MICROWAVE OVEN HAVING AN EXTRA-LOW-VOLTAGE SAFETY MECHANISM
(FR) FOUR À MICRO-ONDES DOTÉ D'UN MÉCANISME DE SÉCURITÉ EXTRA-BASSE TENSION
Abstract:
(EN) A microwave oven comprises a microwave generator (8) having several semiconductor switches (T1 - T6) driven by a driver circuit (14). Power for the driver circuit (14) is fed through a series of safety switches (S1 - S3) mechanically coupled to the door (2) of the oven. This allows using extra-low-voltage and low-current switches while still providing a reliable means for switching off the oven when its door (2) is being opened.
(FR) Le four à micro-ondes de l'invention comprend un générateur de micro-ondes (8) muni de plusieurs commutateurs à semi-conducteurs (T1 - T6) commandés par un circuit d'attaque (14). Le circuit d'attaque (14) est alimenté par l'intermédiaire d'une série de commutateurs de sécurité (S1 - S3) couplés mécaniquement à la porte (2) du four. Cette configuration permet d'utiliser des commutateurs extra-basse tension et à faible consommation tout en constituant un moyen fiable d'éteindre le four lorsque sa porte (2) est ouverte.
