<P>PROBLEM TO BE SOLVED: To generate no unintended groan sound noise due to difference in revolution speed between cooling fans in structure for performing cooling by using two or more cooling fans. <P>SOLUTION: An induction heating cooker includes: a revolution speed detection part 8 which detects revolution speed of first and second cooling fans 7a, 7b; and a revolution speed control part 9 which inputs detection results of the revolution speed detection part 8 to control the revolution speed of the first and second cooling fans 7a, 7b, in which the revolution speed control part 9 controls the revolution speed of the first and second cooling fans 7a, 7b within a range that no groan sound noise is generated based on the detection results of the revolution speed detection part 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
