Abstract
In a high-frequency energy apparatus, a heat generating element is disposed on a ventilation path of the high-frequency energy apparatus, which path is channeled through a heating chamber. When the heating time is automatically controlled, external air is introduced into the heating chamber, and when the heating time is manually controlled by such a means as a timer, on the other hand, hot air which has been heated by the heat generating element is introduced into the heating chamber so that the deposition of dew on the wall of heating chamber and the obscuring of a viewing panel of the heating chamber due to moisture may be prevented.
