る電気掃除機の床ノズル制御装置。 An agitator with brush bristles flocked in the direction of the rotation axis is installed facing the suction port of the floor nozzle body, and
The agitator is configured to be driven by an electric motor built into the floor nozzle body, and a light emitting element and a light receiving element are predetermined in a space formed along the length between the agitator and the suction port of the floor nozzle body. The light emitting element is disposed at intervals, and the light emitted from the light emitting element is refracted into the space that closely faces the light receiving element to reach the light receiving element, and the light entering the inlet from the outside is passed through and received. 1. A floor nozzle control device for a vacuum cleaner, comprising: a reflective plate having a semi-reflective surface that reaches the light receiving element; and a control circuit that controls the electric motor based on the output of the light receiving element.
