Definitions

• a vacuum cleaner including: a dust separation unit; a dust collection body in which a dust storage chamber is disposed for storing dust separated by the dust separation unit; a pressing member compressing dust stored in the dust storage chamber; and a driving unit disposed at the dust separation unit for actuating the pressing member.
• the main body 100 includes a main body inlet 110, a main body outlet (not shown), and main body grip 140.
• the main body inlet 110 is formed in a front lower portion of the main body 100, and air and dust sucked using the suction nozzle are introduced into the main body 100 through the main body inlet 110. After dust is separated from air, the air is discharged from the main body 100 through the main body outlet.
• the main body grip 140 is formed on an upper portion of the main body 100 so that a user can easily carry the vacuum cleaner 10 using the main body grip 140.
• an air outlet 130 is formed in the main body 100, and a first air inlet 218 is formed in the dust collector 200. Air sucked into the main body 100 is discharged to the dust collector 200 through the air outlet 130 and the first air inlet 218.
• Fig. 4 is a sectional view taken along line I-I' of Fig. 3
• Fig. 5 is a perspective view illustrating the dust collector mount 170 according to the first embodiment.
• the suction motor (not shown) operates to generate a suction force. Owing to the suction force generated by the suction motor, air and dust can be sucked through the suction nozzle (not shown). The air and dust is guided to the main body 100 through the main body inlet 110 and passes through a predetermined passage. Then, the air and dust enter the dust collector 200.
• the dust is separated from the air while swirling down in the first cyclone unit 230 and enters the dust guide passage 232 in a tangential direction.
• the moving direction of the dust is changed.
• the dust is discharged downward through the outlet 234 to the first dust storage chamber 214.
• the vacuum cleaner 900 of the current embodiment includes a main body 910 and the dust collector 1000.
• a suction motor (not shown) is disposed in the main body 910.
• the dust collector 1000 separates dust from sucked air and stores the separated dust.
• Air and dust sucked through a suction nozzle are introduced into the main body 910 through the main body inlet 920.
• a main body outlet 930 is formed at a side of the main body 910 for discharging air from the main body 910 after dust is separated from the air.
• the terminal part 1124 is connected to the compression motor 1100 through a connector 1122.
• the terminal part 1124 is connected to a power supply terminal 942 formed at the dust collector mount 940.
• the dust collector 1000 compresses dust in the same manner as those described in the previous embodiments. Thus, a detailed description thereof will be omitted.
• the dust collector 1300 includes a dust collection body 1310 in which a dust storage chamber is formed, and a cover member 1330 for selectively closing and opening the top of the dust collection body 1310.
• a driving unit 1400 is disposed at the cover member 1330 for driving a pressing member (described later in detail) to compress dust stored in the dust storage chamber of the dust collection body 1310.
• the cyclone part 1321 is a part in which dust is separated from air by a centrifugal force.
• the cyclone part 1321 is formed by the inner wall 1313 and the bottom wall 1312.
• the first pressing member 1440 extends downward from the rotatable member 1430 to a predetermined length.
• the first pressing member 1440 is spaced apart from a rotation centerline of the rotatable member 1430.
• the height of the backflow restriction part 1434 is smaller than the width of the connection passage (P) such that the backflow restriction part 1434 can screen the connection passage (P) partially to form a ring-shaped auxiliary passage (Pl). Dust separated at the cyclone part 1321 can be discharged downward to the dust storage chamber 1322 through the auxiliary passage (Pl).
• the compression motor 1420 stops when the suction motor stops.
• the dust collector 1600 of the current embodiment includes a dust collection body 1610 and a cover member 1620 selectively coupled to an upper side of the dust collection body 1610.
• the dust collection body 1610 of the current embodiment has the same structure as the dust collection body 1310 of the fifth embodiment. Thus, a detailed description thereof will be omitted.
• the power transmission members include a driving gear 1720 and a driven gear
