Abstract

　L'invention porte sur un cuiseur, qui comporte un boîtier (1), une chambre de chauffage (2), un générateur de micro-ondes pour délivrer des micro-ondes à la chambre de chauffage (2), et une porte (3) pour ouvrir et fermer une partie d'ouverture (2a). La chambre de chauffage (2) est disposée dans le boîtier (1), et à la partie d'ouverture (2a) sur le côté avant. La porte (3) a des parties émettrices de lumière (304A, 304B) pour émettre de la lumière dans la chambre de chauffage (2), un élément de fenêtre transparent ou semi-transparent (305), et une partie de blindage contre des micro-ondes (306). L'élément de fenêtre (305) est disposé sur une trajectoire de lumière entre les parties émettrices de lumière (304A, 304B) et la chambre de chauffage (2). La partie de blindage contre des micro-ondes (306) est disposée entre les parties émettrices de lumière (304A, 304B) et l'élément de fenêtre (305), et produit un blindage contre des micro-ondes venant de la chambre de chauffage (2).
