Cleaner
First Claim
1. A cleaner comprising:
- a suction unit configured to guide air into the cleaner;
a suction motor that is configured 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;
a cleaner body that is configured to accommodate the suction motor, and that has a first opening that provides access to an interior of the cleaner body;
an exhaust filter that is configured to be detachably coupled to the cleaner body at the first opening of the cleaner body, the exhaust filter configured to receive and filter air that has passed through the suction motor;
a filter cover that is configured to cover the first opening of the cleaner body at which the exhaust filter is configured to be coupled;
a pre-filter that circumferentially surrounds at least part of the suction motor, and that is configured to filter air that was discharged from the second cyclone unit of the dust separation unit and before the air enters the suction motor; and
a dust container that is configured to store dust that is separated by the dust separation unit and that comprises a dust cover configured to cover a second opening of the dust container that provides access to an interior of the dust container,wherein the second opening of the dust container and the first opening of the cleaner body are located on opposite sides of the dust separation unit, with an axis of a first cyclonic flow of the first cyclone unit configured to pass through the first opening and through the second opening, andwherein, in a state in which the first opening is uncovered, the pre-filter is configured to be inserted through the first opening to surround at least part of the suction motor.

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.
