Cleaner
First Claim
1. A cleaner comprising:
- a suction unit configured to guide air into the cleaner;
an air exhaust configured to discharge air from the cleaner;
a suction motor that comprises a rotary impeller and that is configured to drive a rotation of the 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 comprising a plurality of cyclone bodies that are configured to secondarily separate dust from air that is discharged from the first cyclone unit;
an exhaust filter that is configured to be detachably coupled to the cleaner and that is configured to receive and filter air that has been discharged from the suction motor and the rotary impeller before the air is discharged through the air exhaust; and
an air guide that is disposed circumferentially around the rotary impeller and that comprises a surface that is configured to guide air from a first passage of the cleaner to a second passage of the cleaner, in which (i) the first passage is configured to guide air that is discharged from the second cyclone unit past an outer surface of the suction motor and towards at least one opening of the suction motor through which air flows to the rotary impeller, and (ii) the second passage is configured to guide air that flows from the rotary impeller towards the exhaust filter.

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.

20. A cleaner comprising:
-
a suction unit configured to guide air into the cleaner; 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; a suction motor comprising a rotary impeller and configured to drive a rotation of the rotary impeller via an impeller shaft to generate a suction force that suctions air into the cleaner through the suction unit; an air guide that is disposed circumferentially around the rotary impeller and arranged between a first passage of the cleaner and a second passage of the cleaner such that air flowing from the first passage flows past the air guide and into the second passage, with (i) the first passage configured to guide air that is discharged from the second cyclone unit towards an opening of the suction motor, through which the air flows into the suction motor and subsequently through the rotary impeller, and (ii) the second passage configured to guide air that is discharged from the suction motor towards an outside of the cleaner; and a dust container configured to store dust that is separated by dust separation unit. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
