PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of easily coping with flicker by a high electric motor input by reducing an electric current in starting. SOLUTION: The vacuum cleaner includes: an electric blower 4 for generating suction force; and a suction tool (not shown in the figure) having a brush electric motor 6 for driving a rotary brush (not shown in the figure) which stirs up dust on a floor surface; and a phase control circuit 7 for controlling power consumption of the electric blower 4. When the brush electric motor 6 is started, the power consumption of the electric blower 4 is made to be equal to or less than prescribed power consumption, so that the brush electric motor 6 and the electric blower 4 are prevented from being simultaneously started by full-conduction. Thus, the electric current in starting is reduced thereby to easily cope with the flicker by the high electric motor input. COPYRIGHT: (C)2011,JPO&INPIT |
