HEATING DEVICE

摘要

A heating device having an automatic thawing function which is simple and advantageous in cost compared with a conventional weight sensor and a system for detecting the field strength in a heating chamber with an antenna. A thermister (17) is exposed inside a heating chamber (1) and mounted to the inner surface of a plate constituting the heating chamber to detect the temperature in the heating chamber (1). Using output of the thermister, the progress of heating of a frozen food is measured. Control means (18) controls drive means (20) of high frequency generating means (16) on the basis of information detected.
