Abstract
PURPOSE: In a high-frequency heater in which the sensor provided at the exhaust port of an oven detects relative humidity to control the output of a magnetron oscillator, to improve detection accuracy by introducing a portion of magnetron cooling air into said oven.
CONSTITUTION: A portion Q2 of the cooling air fed by a blower 11 to cool a magneton oscillator 10 is introduced into an oven. The detection signal of the relative humidity sensor 4 provided at the exahst port of said oven is impressed on a comparator 7 through an amplifier 5 and a minimum value holder 6. Said detection signal is compared with a predetermined set value ΔV by said comparator 7, the output of said comparator 7 is supplied to a heating time counting control circuit 8, and said magnetron oscillator 10 is stopped by a controller 9 when a fixed time has elapsed.
