Abstract
The invention provides a vacuum cleaner effectively silencing noise going out forward from the inlet port of a motor-driven blower and securing the smooth inlet of air to the blower. Noise from the inlet port 5d of the motor-driven blower 5 is silenced by a silencing part 10. Namely, this noise advances straight forward inside a guiding wall 4a to a conical cone 11 and enters inside of the cone from a through hole 13b at its side face 13 to be absorbed by a noise absorbing material 14. Otherwise the noise is reflected by the inner face of the wall 4a and the side face 13 of the cone 11 to be attenuated. On the other hand, most of air flowing into the port 5d of the blower 5 from a dust collecting chamber 2 smoothly moves along the side face 13 of the cone 11 as shown by the arrows.
