1. A cleaner comprising:
- a suction unit configured to guide air into the cleaner;
a rotary impeller configured to rotate about an impeller shaft to generate a suction force that suctions air into the cleaner through the suction unit;
a motor that is disposed under the rotary impeller in a state in which the cleaner is oriented with the impeller shaft arranged longitudinally along a vertical direction, and is configured to drive a rotation of the rotary impeller via the impeller shaft;
a dust separation unit that is disposed under the motor in the state in which the cleaner is oriented with the impeller shaft arranged longitudinally along the vertical direction, the dust separation unit comprising;
a first cyclone unit that is configured to separate dust from the air that is suctioned into the cleaner; and
a second cyclone unit that is disposed under the motor in the state in which the cleaner is oriented with the impeller shaft arranged longitudinally along the vertical direction, and is configured to separate dust from air that is discharged from the first cyclone unit; and
a dust container that is disposed under the motor in the state in which the cleaner is oriented with the impeller shaft arranged longitudinally along the vertical direction, and is configured to store dust that is separated by the dust separation unit.

Abstract
A cleaner includes: a suction motor that generates suction force; a dust separation unit that separates dust from air sucked by the suction force; a motor housing that covers the suction motor; a flow guide that surrounds an outer side of the motor housing and guides air discharged from the dust separation unit to the suction motor; and a body that forms an external appearance by surrounding the flow guide and guides air discharged from the suction motor together with the flow guide.

16. A cleaner comprising:
-
a suction unit configured to guide air into the cleaner; a dust separation unit comprising; a first cyclone unit configured to generate a first cyclonic flow that separates dust from the air that is suctioned into the cleaner through the suction unit; and a second cyclone unit that is configured to generate a second cyclonic flow that separates dust from air that is discharged from the first cyclone unit; a rotary impeller that is disposed above the dust separation unit in a state in which the cleaner is oriented with an axis of the first cyclonic flow of the first cyclone unit arranged longitudinally along a vertical direction, and that is configured to generate a suction force that suctions air into the cleaner; a motor that is disposed under the rotary impeller and above the second cyclone unit in the state in which the cleaner is oriented with the axis of the first cyclonic flow of the first cyclone unit arranged longitudinally along the vertical direction, and that is configured to drive a rotation of the rotary impeller; and a dust container that is disposed under the motor in the state in which the cleaner is oriented with the axis of the first cyclonic flow of the first cyclone unit arranged longitudinally along the vertical direction, and that is configured to store dust that is separated by the dust separation unit. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
