  • High frequency heating apparatus
    Patent number: 11937360
    Abstract: A high frequency heating apparatus (1A) includes the following components: a first electrode (11) that is flat; a plurality of flat second electrodes (12) that are flat; a high-frequency power supply (20); a matching unit (30); a controller (40); and an electric field regulator (50). The second electrodes (12) are placed opposite to the first electrode (11). The high-frequency power supply (20) applies a high-frequency voltage to the first electrode (11). The matching unit (30) is placed between the first electrode (11) and the high-frequency power supply (20), and is impedance-matched with the high-frequency power supply (20). The controller (40) controls the high-frequency power supply (20). The electric field regulator (50) individually adjusts the electric field strengths in a plurality of regions located between first electrode (11) and the second electrodes (12). This aspect can reduce uneven heating.
