HIGH FREQUENCY HEATING DEVICE

摘要

A heating device constructed with due consideration given to movable arrangement for heating electrodes, having freedom for installation space and having high reliability. A plurality of substantially U-shaped support bars (14a, 14b) holding a movable electrode (12) have their center of rotation located on the side wall of a heating chamber (10) and are constructed for rotation and lifting/lowering while the lower sides of the substantially U-shaped support bars (14a, 14b) are keeping parallelism with a fixed electrode (13). Therefore, a movable device can be installed on the side wall of the heating chamber and the heating device in its entirety does not have to be increased in height. Further, since the movable electrode is held by the plurality of substantially U-shaped support bars, its parallelism with the fixed electrode can be reliably kept. It is possible to provide a heating device having good heating efficiency and superior performance, and capable of using both dielectric heating and microwave heating.
