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.

First claim

What is claimed is:

1. A handheld vacuum cleaner, comprising:
a suction inlet configured to suction air into the cleaner;
a first cyclone unit configured to separate dust from air that is suctioned through the suction inlet;
a second cyclone unit configured to separate dust from air that is discharged from the first cyclone unit;
a suction motor disposed above the second cyclone unit and including an impeller, the impeller being configured to rotate to thereby suction air through the suction inlet;
a first filter that surrounds at least a part of the suction motor about an axial direction of the suction motor and that is configured to filter air discharged from the second cyclone unit to the suction motor;
a body accommodating the suction motor and the first filter; and
a filter unit coupled to the body and configured to support the first filter in the body, the filter unit having a second filter configured to filter air being discharged to an outside of the cleaner,
wherein the first filter and the second filter are configured, based on the filter unit being separated from the body along a first direction, to be separated along the first direction to the outside of the cleaner.

2. The handheld vacuum cleaner of claim 1 , wherein the suction motor is positioned directly above at least a portion of the second cyclone unit.

3. The handheld vacuum cleaner of claim 1 , wherein the body defines an opening through which the first filter passes to the outside when the filter unit is separated from the body.

4. The handheld vacuum cleaner of claim 3 , wherein, in a state in which the filter unit is coupled to the body, the first filter is disposed below the opening and pressed by the filter unit.

5. The handheld vacuum cleaner of claim 1 , wherein the first filter is configured to be separated based on the filter unit being separated.

6. The handheld vacuum cleaner of claim 1 , wherein the filter unit is configured to be separated from the body in a state in which the suction motor is positioned in the body.

7. The handheld vacuum cleaner of claim 1 , wherein, in a state in which the filter unit is coupled to the body, at least a portion of the second filter is positioned above the first filter.

8. The handheld vacuum cleaner of claim 1 , wherein the filter unit is configured to be coupled to or separated from the body by being rotated.

9. The handheld vacuum cleaner of claim 1 , wherein an outer diameter of the second filter is greater than an outer diameter of the first filter.

10. The handheld vacuum cleaner of claim 9 , wherein the first filter and the second filter are spaced apart from a rotation axis of the impeller in a radial direction.

11. The handheld vacuum cleaner of claim 10 , wherein the first filter and the second filter extend in a circumferential direction about the rotation axis of the impeller.

12. The handheld vacuum cleaner of claim 1 , wherein the first filter is configured to be separated from the body based on the second filter being separated from the body.

13. The handheld vacuum cleaner of claim 12 , wherein the first filter is configured, based on the filter unit being separated from the body, to be exposed to the outside through an opening defined in the body.

14. The handheld vacuum cleaner of claim 1 , further comprising:
a handle coupled to the body and extending in a direction crossing a longitudinal axis of the suction inlet.

15. The handheld vacuum cleaner of claim 1 , further comprising:
a dust container provided at a position opposite to the filter unit with respect to the suction motor and configured to be opened in a direction opposite to a separation direction of the first filter and the second filter.
