HIGH FREQUENCY HEATING DEVICE.

摘要

A high frequency heating device which detects variations in moisture and temperature in the vapor produced by heating food (14) in a heating chamber (13) by using a temperature and relative humidity detector (17), converts them into relative and absolute humidities to determine whether the variation in the absolute humidity has reached a predetermined level, thereby automatically heating or cooling the food. Since this device has a single detector, it produces less error due to detecting errors and changes with time, thereby performing an accurate detection.
