PROBLEM TO BE SOLVED: To provide a rice cooker capable of accurately calculating a power supply voltage when outputting a high frequency power supply without complicating a circuit configuration with an inexpensive configuration.SOLUTION: A rice cooker includes: a main body; an inner pot stored inside the main body; a lid body provided in the main body, and covering over the inner pot; induction heating means provided inside the body, and heating the inner pot; radiation type heating means provided inside the main body, in the lid body, or in both; a switching element 35 configuring an inverter circuit supplying power to the induction heating means; frequency detection means 39 for detecting a drive frequency of the switching element 35; and control means having a microcomputer for controlling the radiation type heating means, the switching element, and the frequency detection means 39. The control means calculates a power supply voltage from the drive frequency of the switching element 35 detected by the frequency detection mean 39, and controls a power supply rate to the radiation type heating means such that an output of the radiation type heating means becomes constant according to the calculated power supply voltage. |
