HIGH-FREQUENCY HEATING APPARATUS

To prevent parts within a heating chamber from melting to thereby secure the safety of a goods even when a user sets an arbitrary time and operates. There are provided with a temperature detector 5 for detecting the temperature of a food within the heating chamber 1 in a non-contact manner, a high-frequency generator 14 for generating a microwave to heat the food within the heating chamber, and a controller 7 for controlling the high-frequency generator based on an output from the temperature detector. The controller is configured in a manner that when a user sets an arbitrary time and inputs a cooking start operation, in a menu for executing the high-frequency heating during the set time, the output level of the high-frequency generator is controlled so as to be reduced when the temperature obtained from the temperature detector increases a predetermined value or more. Since the output level for the high-frequency heating is reduced when the temperature obtained from the temperature detector increases the predetermined value or more, resin parts and ceramic parts within the heating chamber can be protected from melting.
