Abstract

A cleaner includes: a main body that has an opening; a suction motor that is disposed in the main body and generates suction force; and a filter unit that includes an exhaust filter for filtering air discharged from the suction motor, the filter unit being inserted into the main body through the opening and being separated from the main body, wherein when the filter unit is combined with the main body, a portion of the filter unit protrudes out of the main body, and a portion of the exhaust filter is positioned inside the main body and the other portion of the exhaust filter is positioned outside the main body.

Claims

1. A cleaner comprising:

a main body that defines an opening;

a suction motor that is disposed in the main body and configured to generate suction force to thereby suction air; and

a filter unit that includes an exhaust filter, the exhaust filter being configured to filter air discharged from the suction motor, the filter unit being configured to be inserted into and separated from the main body through the opening,

wherein, based on the filter unit being coupled to the main body, a portion of the filter unit protrudes out of the main body, a first portion of the exhaust filter is positioned inside the main body, and a second portion of the exhaust filter is positioned outside the main body.

2. The cleaner of claim 1, wherein, based on the filter unit being coupled to the main body, the filter unit is seated on an upper end of the main body.

3. The cleaner of claim 1, wherein the main body includes a dust separation unit that is configured to separate dust from the suctioned air using cyclonic flow, and

wherein an axis of the cyclonic flow passes through the filter unit.

4. The cleaner of claim 1, wherein the filter unit is configured to be attached to the main body via rotation, and

wherein the filter unit is configured, based on being rotated to be attached or detached, to move in a direction parallel with a longitudinal axis of the main body.

5. The cleaner of claim 1, further comprising a flow guide that surrounds the suction motor and is configured to guide air in the main body,

wherein the filter unit further includes a filter frame that that is configured to receive the exhaust filter, the filter frame being coupled to the flow guide.

6. The cleaner of claim 5, wherein the flow guide includes a fixing rib that protrudes outward from the flow guide and extends at an angle along an outer surface of the flow guide, and

wherein the filter frame includes a rib seat that is configured to receive the fixing rib, the rib seat extending at an angle along an inner surface of the filter frame.

7. The cleaner of claim 6, wherein the fixing rib includes a fixing protrusion, and

wherein the filter frame defines a slot that is configured to receive the fixing protrusion based on the fixing rib being inserted into the rib seat.

8. The cleaner of claim 6, wherein the filter frame includes:

an inner frame;

an outer frame that is spaced from the inner frame; and

a filter cover that covers a bottom of the exhaust filter,

wherein the exhaust filter is located between the inner frame and the outer frame, and

wherein the rib seat is located between the inner frame and the filter cover.

9. The cleaner of claim 8, wherein the filter cover includes a rib coupling portion that is inclined to be coupled to the fixing rib, and

wherein the inner frame defines a recession that is recessed upwardly from a bottom surface of the inner frame, the recession and the rib coupling portion forming the rib seat.

10. The cleaner of claim 9, wherein the filter cover includes:

a ring-shaped inner body;

an outer body that is spaced apart from the inner body; and

a connection body that connects the inner body to the outer body, the connection body defining an opening that is configured to pass air,

wherein the inner body includes the rib coupling portion that protrudes inwardly from an inner surface of the inner body.

11. The cleaner of claim 10, wherein, based on the flow guide passing through the inner body, the fixing rib is inserted in the rib seat.

12. The cleaner of claim 1, wherein the filter unit includes:

a filter frame that is configured to receive the exhaust filter;

a sealing member that is coupled to an edge of the filter frame and configured to prevent air leaking out from between an inner side of the main body and the filter frame; and

a support step that protrudes from the inner side of the main body and is configured to seat the sealing member.

13. A cleaner comprising:

a main body that defines an opening;

a suction motor that is disposed in the main body and configured to generate suction force to thereby suction air;

a first filter that is configured to filter air that flows into the suction motor; and

a filter unit that includes a second filter, the second filter being configured to filter air discharged from the suction motor, the filter unit being configured to be inserted into and separated from the main body through the opening,

wherein the first filter surrounds at least a portion of the suction motor, and the first filter is exposed to an outside based on the filter unit being separated from the main body.

14. The cleaner of claim 13, wherein the filter unit further includes a filter frame that is configured to receive the filter, and

wherein, based on the filter unit being coupled to the main body, the second filter surrounds the first filter.

15. The cleaner of claim 13, wherein the main body further includes a body that is configured to receive both of the first filter and the second filter.

16. The cleaner of claim 13, wherein the main body further includes a dust separation unit that is configured to separate dust from the suctioned air using cyclonic flow, and

wherein an axis of the cyclonic flow passes through both of the first filter and the filter unit.

17. A cleaner comprising:

a main body that defines an opening;

a suction motor that is disposed in the main body and configured to generate suction force to thereby suction air; and

a filter unit that includes an exhaust filter, the exhaust filter being configured to filter air discharged from the suction motor, the filter unit being configured to be inserted into and separated from the main body through the opening,

wherein the filter unit is configured to be attached to the main body via rotation, and

wherein the filter unit is configured, based on being rotated to be attached or detached, to move in a direction parallel with a longitudinal axis of the main body.
