HUMIDITY DETECTING DEVICE FOR AN ELECTRONIC RANGE

摘要

a humidity detector for detecting a humidity value by a variation of a constant current according to humidity and air between upper and lower electrode plates which are arranged by a predetermined interval on an exhaust port of an microwave oven; a frequency converter for converting the humidity value into a frequency signal; and a main controller for inputting the frequency signal outputted from the frequency converter and converting the signal into a humidity value, to thereby execute a heating control.
