The present invention provides an electric dust collector which has the following advantages: low price and high versatility. The electric dust collector (11) is provided with an electric blower (15). The electric dust collector (11) is provided with a control component (31) that is used for setting an input phase angle of the electric blower (15). The electric dust collector (11) is provided with a variable resistor (33) which can variably set a resistance value and variably setting the power of the electric blower (15) through the variable setting to the resistance value. The electric dust collector (11) is provided with a control unit (32). The control unit (32) corresponds with the resistance value of the variable resistor (33) and avoids a preset phase angle range that generates higher harmonic wave above a preset threshold for determining the input phase angle of the electric blower (15), which is set by the control component (32). |
