CA 2074579
A vacuum cleaner with the noise greatly reduced is disclosed. The vacuum cleaner includes a blower assembly which comprises: a vibration absorbing means for absorbing the vibrations occurring due to the high speed revolutions of electric blower 1; a noise shielding means for shielding the noise so as for the noise from the electric blower not to be propagated to the outside; a flow path changing means for curving and extending the flow path by banding the flow path of the air after passing through the electric blower; and a noise absorbing means for suppressing the noise by absorbing the noise propagated through the flow path. The vacuum cleaner of the present invention further includes blower assembly receiving section 41, which finally shields and absorbs the noise. Further, a vibration absorbing means is installed on the contact portion between the vacuum cleaner main body and the blower assembly, and air suction hole 48 is farmed on partition wall 44 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 of air.
