Document Type and Number:
WIPO Patent Application WO/2024/070152
Kind Code:
A1
Abstract:
The present application discloses a method for controlling a suction motor of a vacuum cleaner equipped with a suction source that generates suction power for suctioning dust by rotating a rotary vane by the suction motor. The control method comprises a motor control step for controlling the rotational frequency of the suction motor so that the operating noise emitted from the suction source changes according to musical notes in a prescribed musical score. In the case where two musical notes representing the same sound are consecutively written in the prescribed score without being connected by a tie, control is performed, in the motor control step, on the rotational frequency of the suction motor such that an insert sound having a frequency that is different from said sound by a halftone or more is emitted between the sounds represented by said two musical notes.
