HIGH-FREQUENCY ELECTROMAGNETIC COOKING DEVICE

摘要

PURPOSE:To protect the work coil of an inverter without turning off the whole device. CONSTITUTION:A cooling fan 7 is provided on one side of a pan 5 on a top plate 2. An aluminum wire having the diameter of 1.2mm is wound about 20 turns on the side wall 5a of the pan 5 to form an antenna coil 8. Leakage flux is coupled with the antenna coil 8 to generate an alternating current. The antenna coil 8 is connected to a DC motor 11 via a rectifier circuit to operate the cooling fan 7.
