Abstract

An electric cleaner has an electric blower (18) for producing sucking force, a sensor (36) for detecting that at least either a temperature or a pressure is at a set value, and a control circuit for controlling the operation of the electric blower (18). The control circuit has a drive portion (20) for supplying AC power to the electric blower (18) in accordance with a control signal, a charging/discharging circuit (22) for charging and discharging a capacitor and outputting a control signal to the drive portion (20) when a charge voltage is equal to or more than a predetermined value, and a resistor body (30) with a resistance value. The control circuit switches, in accordance with detection by detecting means, between the conduction and cutout of photo-couplers (26) for electrically connecting one end and the other end of the resistor body (30).
