  • a centrifugal action of the whirling current ascending by a suction force of the suction motor a relatively large dust is separated from the air drawn in into the first cyclone chamber 59.
  • the separated dust is moved toward and collected into the first dust collecting chamber 60.
  • the air from which the dust is first separated passes through the grill member 68 to filter off a fine dust therefrom again, and flows into the second air inlets 70 of the two cyclones 71a and 71 b via the air drawing-in pipe 67 and the guide passage 75.
  • the air flowed into the second air inlets 70 is changed into a whirling current while being dashed against an inner circumferential surface of the second cyclone chamber 72 and guided by the guide pipe 73 and the discharging pipe 77.
  • a dust is second separated from the air by the centrifugal force of the whirling current.
  • the dust separated from the air in the second cyclone chamber 72 is collected into the second dust collecting chamber 61 through the dust discharging part 74 and the dust discharging passage 76.
  • the air from which the dust is second separated passes through the grill 77a to filter off a fine dust therefrom again, and discharges into the discharging passage formed in the seating part 80 through the discharging pipe 77.
  • the discharged air is united into one in the discharging passage and discharged to the outside through the suction motor.
  • the user grasps the handle 62 and draws out the entire of the dust separating unit 50 from the seating part 80. And then, as illustrated in FIG. 3 , the user pulls the second cyclone unit 65 up while grasping the handle 62. As a result, the upper edges of the first and second dust collecting chambers 60 and 61 are separated from the groove part 66a of the first cover 66 to open the upper parts of the first and second dust collecting chambers 60 and 61. In this state, the dust collected in the first and second dust collecting chambers 60 and 61 is removed from the first and second dust collecting chambers 60 and 61 and dumped on a dustbin, and the dust removing operation is completed.
  • the user places the second cyclone unit 65 on the first cyclone unit 55 and then inserts the upper edges of the first and second dust collecting chambers 60 and 61 into the groove part 66a of the first cover 66 to couple the second cyclone unit 65 with the first cyclone unit 55. And then, the user grasps the handle 62 and pushes the dust separating unit 50 into the recess 81 of the seating part 80 to mount the dust separating unit 50 in the seating part 80. At this time, the second cover 69 closes up the first opening 11a of the outer casing 11 and the front surface of the first dust collecting chamber 60 closes up the second opening 11b of the outer casing 11.
  • the first air inlet 56 is connected with the air drawing-in passage communicating in fluid with the connection socket 81a coupled to the suction hose 15, and the rear ends of the discharging pipes 77 of the two cyclones 71a and 71b are coupled with inlets of the discharging passage. Also, the two cyclones 71a and 71b and the handle 62 are projected to the outside of the outer casing 11 through the first and the second openings 11a and 11b of the outer casing 11, respectively. As a result, the mounting operation is completed.
  • the vacuum cleaner is configured, so that the entire of the large volume of dust separating unit, such as the multi cyclone dust separating apparatus, having the plurality of cyclones, that is, the first and the second cyclone units, is detachably mounted to the cleaner body. Accordingly, in maintenance and repair, the user can separate the entire of the dust separating unit from the cleaner body and then move the dust separating unit to the outer wide area to maintain and repair the dust separating unit thereat.
  • the entire of the large volume of dust separating unit such as the multi cyclone dust separating apparatus, having the plurality of cyclones, that is, the first and the second cyclone units
  • the vacuum cleaner according to the exemplary embodiment of the present disclosure is configured, so that the first and the second cyclone units of the dust separating unit are detachably coupled to or with each other. Accordingly, the first and/or the second cyclone units can be easily maintained and repaired.
  • the vacuum cleaner according to the exemplary embodiment of the present disclosure is configured, so that some components of the large volume of dust separating unit, such as the multi cyclone dust separating apparatus, that is, at least the handle of the first cyclone unit and the cyclones of the second cyclone unit, are arranged to project to the outside. Accordingly, there is no need for forming the seating part of mounting the dust separating unit to have the height and the width identical to or larger than the entire height and the entire width of the dust separating unit.
  • the vacuum cleaner according to the exemplary embodiment of the present disclosure can detachably mount the large volume of dust separating unit, but design the cleaner body to have about the same size as the dust separating unit having the single cyclone in the conventional vacuum cleaner.
  • the vacuum cleaner according to the exemplary embodiment of the present disclosure can detachably mount the large volume of separating unit, such as the multi cyclone dust separating apparatus, for superior dust-separating performance while not greatly increasing the vacuum cleaner in size.
