<P>PROBLEM TO BE SOLVED: To suppress the vibration and noise of a casing by controlling the driving of a washing motor. <P>SOLUTION: A clothes treatment apparatus includes a casing 1, a rotary drum 3 provided in the casing 1 for containing clothes or the like, an induction motor 12 for driving the rotary drum 3, and a control section 13 for supplying variable-frequency power to the induction motor 12 to drive the induction motor 12. The control section 13 performs the control by preventing the variable frequency or its harmonics from coinciding with the resonance frequency of the casing 1 and by setting a driving frequency so as to maximize the efficiency of the induction motor 12 at a frequency other than the resonance frequency. Thus, the vibration and noise of the casing can be suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
