One end 61 of each connection unit 60 is connected to the corresponding auxiliary suction port 53, and the other end 62 of each connection unit 60 is connected to the corresponding second opening 33, such that the auxiliary suction ports 53 communicate with the corresponding second openings 33.
  • connection unit 60 is realized by a flexible pipe, which maintains the secure connection between the auxiliary suction ports 53 and the corresponding second openings 33 irrespective of movement of the suction unit 20 and the hinged rotation of the suction duct 30.
  • the second openings 33 are defined in the respective hinge shafts 31, formed for the hinged rotation of the suction duct 30, to prevent the leakage of the suctioned air from between the auxiliary suction ports 53 and the corresponding second openings 33 irrespective of the movement of the suction unit.
  • the flow turbulence in the guide channel is great at the outer edges of the guide channel where the air currents A, B, and C join one another. Consequently, the auxiliary suction ports 53 are preferably formed at the outer edges of the guide channel.
  • the guide channel 52 is formed such that the heights of the edges, i.e. the front edge 54, the rear edge 55, and the side edge 56, of the guide channel 52 are approximately the same. This structure reduces the flow turbulence occurring by decreasing the height of the side edge of the guide channel to increase the amount of air introduced from the side as in the conventional art to, thereby reducing noise.
  • the guide channel is constructed such that the height of the side edge 56 of the guide channel is the same as those of the front and rear edges of the guide channel, although the guide channel may be constructed such that the height of the side edge of the guide channel is less than those of the front and rear edges of the guide channel as in the conventional art.
