ABSTRACT:
A vacuum cleaner with noise and vibration greatly reduced is disclosed. The vacuum cleaner includes a blower assembly which comprises a vibration absorbing assembly for absorbing vibrations occurring due to high speed revolutions of electric blower, a noise shielding assembly for shielding the noise so as to prevent the noise from being propagated from the electric blower to outside of the vacuum cleaner, a flow path changing assembly for curving and extending a flow path by bending the flow path of air after passing through the electric blower, and a noise absorbing assembly suppressing the noise by absorbing the noise propagated through the flow path. The vacuum cleaner further includes a blower assembly receiving section, which shields and absorbs the noise. Further, a vibration absorbing assembly is disposed on a contact portion between a vacuum cleaner main body and the blower assembly, and an air suction hole is formed on a partition wall which separates the dust collecting room and the blower receiving room from each other, so that the noise generated by the electric blower should be shielded without giving any increased resistance to the flow path of air.
