Contexte:

the backward power detection unit may include a quadrature detection unit, and the quadrature detection unit may be configured to perform quadrature detection of the backward power by using the radio-frequency power generated by the radio-frequency power generation unit, to thereby detect an in-phase detection signal and a quadrature detection signal to be used to calculate the amplitude and the phase of the reflected wave and the amplitude and the phase of the through wave.

the control unit may be configured to cause each of the plurality of radio-frequency power units to detect the backward power while heating the object; and execute the re-search process in the case where at least one of a plurality of backward powers detected exceeds a threshold.

a plurality of radio-frequency power units each including (i) a radiation unit configured to radiate the radio-frequency power of a phase changed by the variable phase shift unit to the heating chamber, and (ii) a backward power detection unit configured to detect backward power constituting a part of the radio-frequency power radiated from the radiation unit and incident into the radiation unit from the heating chamber; and a control unit configured to set a frequency for the radio-frequency power generation unit and a phase shift amount for the variable phase shift unit.
