  • Patent number: 5293664
    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.
