<P>PROBLEM TO BE SOLVED: To reduce a thermal influence on an LED lamp irradiating the inside of a heating chamber. <P>SOLUTION: A control device 26 includes an LED lamp control part 34 configured such that during an oven mode or a grill mode, when the output of a heating heater 12 is higher than a first set output, the drive voltage of the LED lamp 18 is lowered to reduce the luminance of the LED lamp 18 in comparison with a set luminance in consideration of light emitted from the heating heater 12. Meanwhile, when the output of the heating heater 12 is lower than a second set output, the drive voltage of the LED lamp 18 is raised to set the luminance of the LED lamp 18 to the set luminance or higher. Thus, a large fluctuation in a total temperature of the atmospheric temperature and self-heating temperature of the LED lamp 18 is suppressed, and the thermal influence on an LED module is reduced to suppress a reduction in service life. Further, power consumption of the LED lamp 18 is reduced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
