  • the bristles 31 of the brush 30 are uniformly installed on the primary brush 30 in a longitudinal direction of the primary brush 30 as a plurality of rows.
  • the primary brush driving device 40 is composed of: a driving motor 41 for providing a driving force; and a driving force transmitting unit 42 for transmitting a driving force of the driving motor 41 to the primary brush 30 so that the primary brush 30 can be reciprocatingly rotated within a range of a predetermined angle.
  • the driving force transmitting unit 42 is composed of: a rotary link 44 fixed to a motor shaft 43 of the driving motor 41 and coaxially rotated together with the motor shaft 43; a hinge bracket 45 installed at one side of an outer circumferential surface of the primary brush 30; and a connecting rod 46 having one end hingedly connected to the rotary link 44 at a position eccentric from a rotation center of the rotary link 44 and having another end hingedly connected to the hinge bracket 45 thus to perform an angular reciprocating motion by a rotation of the rotary link 44.
  • the driving force transmitting unit 42 converts a rotational motion of the motor shaft 43 of the driving motor 41 into a forward and backward reciprocating rotation of the primary brush 30.
  • the inlet 51 of the first suction duct 50 is arranged at a rear side of the primary brush 30 and is extended to a rear side of the housing 110, and an outlet 52 of the first suction duct 50 is connected to the connection pipe 115.
  • the primary brush 30 When the primary brush 30 is forwardly rotated, that is, the primary brush 30 is rotated counterclockwise as shown in Fig. 6, the first suction duct 50 serves as a primary path of dust brushed by the bristles 31 of the primary brush 30 thus to be moved to the rear side of the suction port 20.
  • the inlet 61 of the second suction duct 60 is arranged to be opened towards a floor at the front side of the primary brush 30 and is extended along an upper circumference of the suction port 20, and an outlet 62 of the second suction duct 60 is connected to the first suction duct 50.
  • the second suction duct 60 serves as a secondary path of dust brushed by the bristles 31 of the primary brush 30 thus to be moved to the front side of the suction port 20.
  • the auxiliary brush 70 is disposed between the primary brush 30 and the inlet 61 of the second suction duct 60, and the bristles 71 are sequentially installed at an outer circumferential surface of the auxiliary brush 70 in a circumferential direction.
  • the rotational force transmitting unit 80 is composed of a driving pulley 82 connected to a motor shaft 81 extended from the fan motor, a driven pulley 84 installed at one side of the auxiliary brush 70, and a belt 83 for connecting the driving pulley 82 and the driven pulley 84.
  • the auxiliary brush 70 is forwardly rotated, that is, is counterclockwise rotated in Fig. 6, and moves dust brushed by the primary brush 30 rotating in a backward (i.e., clockwise) direction, thus to be moved to the front side of the suction port 20 toward a rear side of the suction port 20.
  • the auxiliary brush 70 can be backwardly rotated, that is, can be clockwise rotated in Fig. 6, and can induce dust brushed by the primary brush 30 rotating in a backward (i.e., clockwise) direction, thus to be moved to the front side of the suction port 20 toward the inlet 61 of the second suction duct 60.
  • a rotational force is generated at the driving motor 41.
  • the rotational force of the driving motor 41 is transmitted to the primary brush 30 through the driving force transmitting unit 42, the primary brush 30 is reciprocatingly rotated within a range of a predetermined angle.
  • the primary brush 30 when the primary brush 30 is backwardly rotated, that is, the primary brush 30 is rotated clockwise, the bristles 31 of the primary brush 30 brush dust on the floor towards the front side of the suction port 20. Also, the bristles 71 of the auxiliary brush 70 brush the floor, and move dust brushed by the primary brush 30 thus to be moved to the front side of the suction port 20 toward the rear side of the suction port 20.
  • the dust moved to the rear side of the suction port 20 by a rotation of the auxiliary brush 70 is introduced into the inlet 51 of the first suction duct 50.
  • a part of dust that has not moved to the rear side of the suction port 20 by the auxiliary brush 70 is introduced into the inlet 61 of the second suction duct 60, flows along the second suction duct 60, and is introduced into the first suction duct 50 through the outlet 62 of the second suction duct 60.
