Cleaner
First Claim
1. A cleaner comprising:
- a suction unit configured to guide air into the cleaner;
a suction motor configured to drive a rotation of a rotary impeller via an impeller shaft to generate a suction force that suctions air into the cleaner through the suction unit;
a dust separation unit comprising;
a first cyclone unit configured to separate dust from air that is suctioned into the cleaner through the suction unit; and
a second cyclone unit configured to separate dust from air that is discharged from the first cyclone unit; and
a printed circuit board (PCB) that is configured to control an operation of the suction motor, and that is disposed between the rotary impeller and the second cyclone unit of the dust separation unit.

Abstract
A cleaner includes: a suction unit; a suction motor that generates suction force for sucking air through the suction unit and includes an impeller; a dust separation unit that includes one or more cyclone units generating cyclonic flow to separate dust from air flowing inside through the suction unit; a dust container that stores dust separated by the dust separation unit and is disposed under the suction motor; a battery disposed behind the dust container to supply power to the suction motor; and a handle disposed behind the suction motor, wherein a rotational axis of the impeller and an axis of the cyclonic flow vertically extend and an extension line from the rotational axis of the impeller passes through the one or more cyclone units.
