機の電力制御回路。[Claims for Utility Model Registration] (1) The power of the electric blower is controlled by a phase control circuit that detects the potential difference between both ends of the volume at hand and controls the trigger timing of the bidirectional thyristor. By detecting the difference in potential and comparing it with a comparator, a potential signal at both ends of the volume is detected. A valve body equipped with a magnet is provided in the air flow path of the electric blower, and a magnetic sensing element is placed opposite the magnet. A power control circuit for a vacuum cleaner, characterized in that the magnetic sensing element is provided with a signal from an auto circuit that amplifies the output of the magnetic sensing element due to a change in the distance between the magnet. (2) The volume has two sliding contact surfaces,
Claims for registration of a utility model in which one surface is divided in the middle of sliding and connected at the first resistor, and the other surface is configured so that the second resistor and the slider do not come into contact at the starting point or the ending point. A power control circuit for a vacuum cleaner according to item 1.
