  • Publication number: 20120043316
    Abstract: A high-frequency heating equipment includes temperature sensor (21) that is mounted with mounting bracket (22) such that temperature sensor (21) can be pressed by a lateral face of cooling fins and an end of temperature sensor (21) points to an anode of magnetron (3). This structure allows positively preventing magnetron (3) from falling into a thermal runaway which invites a breakdown of magnetron (3), and allows determining in a reliable manner whether the operation is a no-load running or a light-load running. The high-frequency heating equipment thus achieves stable performance.
