HIGH FREQUENCY HEATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To satisfactorily cool a power supply section and a high frequency oscillation apparatus even when they are disposed in a small space in a high frequency heating apparatus including a machine chamber below a heating chamber. SOLUTION: There are disposed a body 1, a heating chamber 4 in the body 4, and a second cooling fan 8 frontally of a machine chamber 5 located in a space between the heating chamber 4 and a bottom plate of the body 1 and a first cooling fan 9 backwardly of the second cooling fan 8. Hereby, even when a high frequency heating apparatus 6 and a power supply section 7 are disposed in a narrow space, both of sucking of rich cold fresh air from a front side of the machine chamber 5 and of sucking of the first cooling fan 9 located on the backward side are effectively applied to satisfactorily cool the power supply section 7 and the high frequency oscillation apparatus 6.
