- the suction nozzle assembly 30 is connected to a lower part of the extended tube 20 to draw in a dust or dirt along with an air from the surface to be cleaned.
- FIGS. 3 through 5 exemplify the dust separating unit 50 according to the exemplary embodiment of the present disclosure.
- the dust separating unit 50 as a multi cyclone dust-separating apparatus having a plurality of cyclones, includes a first cyclone unit 55 and a second cyclone unit 65.
- the first cyclone unit 55 which draws in the air drawn in through the suction nozzle assembly 30, the extended tube 20 and the suction hose 15 from the surface to be cleaned and first centrifugally separates the dust from the air, is configured, so that it draws in the air at a lower part thereof and discharges the air at an upper part thereof.
- the first cyclone unit 55 is provided with a first cyclone chamber 59 in the form of a cylinder having a first air inlet 56 formed on a side of the lower part thereof.
- the first air inlet 56 is coupled with an air drawing-in passage (not illustrated) formed in a lower side of the front part of the outer casing 11 to communicate in fluid with a connection socket 81a coupled to the suction hose 15.

- a spiral guide 58 is formed on an outer circumferential surface of the center pipe 57 to guide the air to rotate along the center pipe 57.
- a first dust collecting chamber 60 is disposed around the first cyclone chamber 59 to collect and store the dust centrifugally separated at the first cyclone chamber 59.
- the first dust collecting chamber 60 is formed in a tub shape with a semicircular cross section.
- the first dust collecting chamber 60 has a height higher than that of the first cyclone chamber 59, so that it can draw in the dust from the air whirling in the first cyclone chamber 59.
- the first dust collecting chamber 60 forms an outer appearance of the first cyclone unit 55, and is configured, so that a front surface thereof closes up the second opening 11b when the dust separating unit 50 is mounted on the seating part 80, as illustrated in FIG. 1 .
- the front surface of the first dust collecting chamber 60 may be formed of a transparent plastic material, so that a user can see, from the outside, whether it is filled with the dust.

- the handle 62 is formed on a portion (that is, the front surface) opposite to a portion (that is, a rear surface) of the first dust collecting chamber 60 to which the second dust collecting chamber 61 is located. Because the whole front-and-rear width of the first and the second dust collecting chamber 60 and 61 is formed in the size corresponding to the front-and-rear width of the accommodating space 83 of the recess 81, the handle 62 is projected to the outside through the second opening 11b of the outer casing 11.
- the second cyclone unit 65 which second centrifugally separates a dust from the air discharged from the first cyclone unit 55, is detachably coupled with the first cyclone unit 55 above the first cyclone unit 55, as illustrated in FIG. 3 .
- the second cyclone unit 65 is provided with a first cover 66 to open and close up upper parts of the first and the second dust collecting chambers 60 and 61 of the first cyclone unit 55.
- a groove part 66a is formed on an undersurface of the first cover 66 to correspond to upper edges of the first and the second dust collecting chamber 60 and 61.

- An air drawing-in pipe 67 is formed on a center of the undersurface of the first cover 66 to draw in the air discharged from the first cyclone chamber 59 after the dust is separated at the first cyclone chamber 59.
- a grill member 68 is formed on a lower part of the air drawing-in pipe 67, and has a plurality of air holes to filter a fine dust from the discharged air.
- the grill member 68 is illustrated as being integrally formed with the air drawing-in pipe 67, but it can be separately formed from the air drawing-in pipe 67. The grill member 68 is projected into the first cyclone chamber 59, so that it is maintained in a spaced-apart relation to the center pipe 57.
- a guide partition 66b is formed in the first cover 66.
- the guide partition 66b forms a guide passage 75 to branch off and guide the air drawn in into the air drawing-in pipe 67 through the grill member 68 into second air inlets 70 of the horizontally arranged cyclones 71a and 71 b to be described later.
- a thickness of the first cover 66 having the guide passage 75 is formed in such a size that a whole height of which a height of the first cyclone unit 55 is added thereto conforms to the height of the accommodating space 83 of the recess 81, that is, in such a size that when the dust separating unit 50 is mounted in the accommodating space 83 of the recess 81, the cyclones 71a and 71 b disposed on the second cover 69 are projected to the outside through the first opening 11a.
- the second cover 69 is disposed on the first cover 66.
- the second cover 69 is detachably coupled with an upper edge of the first cover 66 and an upper edge of the guide partition 66b by a projected part 69a formed on a lower part of the second cover 69.
- the second cover 69 may be integrally formed with the first cover 66.
- the second cover 69 is formed in a size and a shape (that is, a semicircular shape) corresponding to the first opening 11a of the outer casing 11, so that when the dust separating unit 50 is mounted on or separated from the seating part 80, it can close up or open the first opening 11a.
- a plurality of, for example, two cyclones 71a and 7 1 b are installed on the second cover 69 to second separate a dust from the air by using a centrifugal force.
- the two cyclones 71 a and 71 b are symmetrically arranged in parallel and adjacent to each other. Because the two cyclones 71a and 71 b are formed in such a size that a height of which the height of the first cyclone unit 55 and the thickness of the first cover 66 are combined conforms to the height of the accommodating space 83 of the recess 81 as described above, they are projected to the outside through the first opening 11a of the outer casing 11 when the dust separating unit 50 is mounted on the seating part 80.
- each of the cyclones 71a and 71b is arranged, so that a line of center axis thereof is positioned in a right angle to a line of center axis of the whirling current in the first cyclone chamber 59.
- Each of the cyclones 71a and 71b includes a second air inlet 70, a second cyclone chamber 72, a guide pipe 73, a discharging pipe 77, and a dust charging part 74. Since each of the cyclones 71a and 7 1 b has the same elements and functions, only one cyclone 71a will be explained.
- the second air inlet 70 at a lower end thereof is coupled with the guide passage 75 and at an upper end thereof is coupled in a tangential shape to a front side (a left side in FIG. 4 ) of the second cyclone chamber 72.
- the second cyclone chamber 72 which provides a space to allow the air drawn in through the second air inlet 70 to whirl, may be formed in a cylinder shape.
- the second cyclone chamber 72 may be formed in a convex cylinder shape or a truncated cone shape.
- the second cyclone chamber 72 may be formed of a transparent plastic material.
- the guide pipe 73 and the discharging pipe 77 are arranged in the front and the rear of the second cyclone chamber 72 to face to each other while having the same center axis.
- the discharging pipe 77 has a grill 77a disposed on a front end thereof to filter a fine dust from the air discharged from the second cyclone chamber 72.
- the grill 77a may be omitted or removed, as in the second cyclone unit 65' of the modified example illustrated in FIG. 7 .
- the discharging pipe 77 at a rear end (a right side end in FIG. 4 ) thereof is penetrated through and slightly projected from the second cyclone chamber 72. Accordingly, when the dust separating unit 50 is mounted on the seating part 80, the rear end of the discharging pipe 77 is connected to an inlet of a discharging passage (not illustrated) formed in the seating part 80 to communicate in fluid with the suction motor.
- a discharging passage not illustrated
- the dust charging part 74 is arranged below a rear end of the second cyclone chamber 72 to send the fine dust centrifugally separated from the air to the second dust collecting chamber 61 of the first cyclone unit 55 through a dust discharging passage 76 of the first cover 66.
- the dust separating unit 50 is illustrated and explained as being the multi cyclone dust separating apparatus including the second cyclone unit 65 with the two cyclones 71a and 71b, the present disclosure is not limited thereto.
- the dust separating unit 50 may be formed in a configuration including a second cyclone unit with a plurality of cyclones arranged in a radial direction above a first cyclone unit.
- the vacuum cleaner 1 is configured, so that the entire of the dust separating unit 50 having the plurality of cyclones, that is, the first and the second cyclone units 55 and 65 is detachably mounted to the cleaner body 10. Accordingly, in maintenance and repair, the user can separate the entire of the dust separating unit 50 from the cleaner body 10 and then move the dust separating unit 50 to an outer wide area to maintain and repair the dust separating unit 50 thereat.
- the vacuum cleaner 1 according to the exemplary embodiment of the present disclosure is configured, so that the first and the second cyclone units 55 and 65 of the dust separating unit 50 are detachably coupled to or with each other. Accordingly, the first and/or the second cyclone units 55 and/or 65 can be easily maintained and repaired.
- the vacuum cleaner 1 is configured, so that some components of the dust separating unit 50, that is, the handle 62 of the first cyclone unit 55 and the cyclones 71a and 71b of the second cyclone unit 65 are arranged to project to the outside. Accordingly, there is no need for forming the seating part 80 of mounting the dust separating unit 50 to have a height and a width identical to or larger than the entire height and the entire width of the dust separating unit 50.
- the vacuum cleaner 1 according to the exemplary embodiment of the present disclosure can detachably mount the dust separating unit 50 with the plurality of cyclones for superior dust-separating performance while not greatly increasing the vacuum cleaner 10 in size.
- the suction motor is operated. As a result, an air is drawn in into the first air inlet 56 through the suction nozzle assembly 30, the extended tube 20 and the suction hose 15 along with a dust or dirt in the vicinity of a surface to be cleaned.
- the air drawn in into the first air inlet 56 is changed into a whirling current while being guided by the spiral guide 58 of the center pipe 57, and is drawn into the first cyclone chamber 59.
- 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 general, a cyclone dust-separating apparatus includes a cyclone unit vertically and elongately installed, a cyclone body with an air inflow part and an air discharging part formed at a side and a top thereof, respectively, and a dust collecting unit connected to a bottom part of the cyclone unit. Accordingly, an external air is drawn in through the side of the cyclone body and lowered while being swirled therein, and a dirt or dust removed from the air is lowered and collected in the collecting unit. However, in such a conventional cyclone dust-separating apparatus, there is a problem that since it has one single cyclone to separate the dust from the air only once, a dust separating efficiency is deteriorated.
- To address the problem as described above, a multi cyclone dust-separating apparatus having a plurality of cyclones is actively being developed. Such a multi cyclone dust-separating apparatus is advantageous in that since it can separate the dust several times from the air using the plurality of cyclones, the dust separating efficiency is improved.

Accordingly, there is no need for forming theseating part 80 of mounting thedust separating unit 50 to have a height and a width identical to or larger than the entire height and the entire width of thedust separating unit 50. Thus, thevacuum cleaner 1 according to the exemplary embodiment of the present disclosure can detachably mount thedust separating unit 50 with the plurality of cyclones for superior dust-separating performance while not greatly increasing thevacuum cleaner 10 in size. - Hereinafter, an operation of the
vacuum cleaner 1 having the detachabledust separating unit 50 according to the exemplary embodiment of the present disclosure constructed as described above will be explained in detail with reference toFIGS. 1 through 6 . - First, as the vacuum cleaner is supplied with an electric power, the suction motor is operated. As a result, an air is drawn in into the
first air inlet 56 through thesuction nozzle assembly 30, theextended tube 20 and thesuction hose 15 along with a dust or dirt in the vicinity of a surface to be cleaned. - The air drawn in into the
first air inlet 56 is changed into a whirling current while being guided by thespiral guide 58 of thecenter pipe 57, and is drawn into thefirst cyclone chamber 59. With 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 thefirst cyclone chamber 59. The separated dust is moved toward and collected into the firstdust 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 thesecond air inlets 70 of the twocyclones pipe 67 and theguide 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 thesecond cyclone chamber 72 and guided by theguide pipe 73 and the dischargingpipe 77. A dust is second separated from the air by the centrifugal force of the whirling current. The dust separated from the air in thesecond cyclone chamber 72 is collected into the seconddust collecting chamber 61 through thedust discharging part 74 and thedust 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 theseating part 80 through the dischargingpipe 77. The discharged air is united into one in the discharging passage and discharged to the outside through the suction motor. - After the cleaning operation is completed as described above, if the user wants to empty the first and the second
