Title: Vacuum cleaner
Inventor: MOCHIDA NORIHITO
IPC: A47L9/28
Filed: 1990-11-22
Abstract: PURPOSE:To prevent a discomfort noise, and to realize the operation pattern being not cyclic without deteriorating the suction force even if a nozzle position is fixed by storing a suitably random operation pattern, sending a speed command pattern based thereon to a revolution speed control part and executing variable speed driving. CONSTITUTION:A cleaner main body 1 is driven by a motor 2, and the motor 2 is controlled as to its rotating speed by a revolution speed control part 3. A timing signal generating part 4 generates a pulse signal of a suitable timing, and a storage device 5 stores a 1/f fluctuation pattern as a suitably random operation pattern of the motor 2. Whenever the pulse signal from the timing signal generating part is generated, a speed command of the 1/f fluctuation pattern is given to the revolution speed control part 3 from the storage device 5. It is defined originally as that which has no periodicity infinitely such as a wind in the 1/f fluctuation natural world. Accordingly, by outputting to the revolution speed control part 3, while switching the command speed of revolution at every specific timing, the pattern operation is executed. In such a way, a cyclic property of a wind-cut sound/motor driving sound is eliminated entirely, and a discomfort sense is eliminated.
