Abstract

L'invention concerne un four à hyperfréquences comportant des éléments rayonnants conducteurs tournants. Le dispositif rayonnant est constitué par plusieurs éléments rayonnants 42 attaqués séprément par des lignes de transmission et tournant autour de l'axe d'un conducteur passant par une ouverture 22 du plan de masse constitué par une paroi 24 du four. Les lignes de transmission sont constituées par des pièces conductrices planes et le plan de masse formé par la paroi du four. L'invention s'applique notamment à des fours de cuisine.The invention relates to a microwave oven comprising rotating conductive radiating elements. The radiating device is formed by several radiating elements 42 attacked separately by transmission lines and rotating around the axis of a conductor passing through an opening 22 of the ground plane formed by a wall 24 of the furnace. The transmission lines are formed by flat conductive parts and the ground plane formed by the wall of the furnace. The invention applies in particular to cooking ovens.
