Abstract

A cleaner is provided. The cleaner includes a suction head, a dust collector connected to the suction head, and a fan motor provided to generate a suction force inside the dust collector, wherein the dust collector comprises a housing having an inlet and an outlet, a fixed body arranged inside the housing, and a rotating body rotatably provided between the housing and the fixed body.

First claim

What is claimed is:

1. A cleaner comprising:
a suction head;
a dust collector connected to the suction head; and
a fan motor provided to generate a suction force inside the dust collector,
wherein the dust collector comprises:
a housing having an inlet and an outlet,
a fixed body arranged inside the housing,
a rotating body rotatably provided between the housing and the fixed body, and covering an outer circumferential surface of the fixed body, and
a flow path formed between the fixed body and the rotating body,

wherein the fixed body comprises a dust collecting chamber formed inside the fixed body and connected to the inlet of the housing, and
wherein the fixed body is configured so that air inside the dust collecting chamber is discharged to the flow path through the outer circumferential surface of the fixed body.

2. The cleaner of claim 1 , wherein the dust collector further comprises a driving device provided to generate a driving force for rotating the rotating body.

3. The cleaner of claim 2 , wherein the driving device is configured to generate a torque according to a rotational axis that is parallel to a direction of an airflow flowing into the dust collector.

4. The cleaner of claim 2 ,
wherein the fixed body is a first fixed element which is arranged between the driving device and the inlet, and
wherein the dust collector further comprises:
a second fixed element arranged between the driving device and the outlet.

5. The cleaner of claim 4 , wherein the inlet, the driving device, and the outlet are arranged in a line.

6. The cleaner of claim 2 , wherein the driving device is provided to adjust a rotational speed of the rotating body such that lift is greater than a centrifugal force generated according to a rotation of the rotating body.

7. The cleaner of claim 1 , wherein the rotating body is provided to rotate about a rotational axis that extends along a direction in which air flowing into the dust collector is discharged.

8. The cleaner of claim 1 , wherein the fixed body comprises a plurality of holes formed through the outer circumferential surface of the fixed body.

9. The cleaner of claim 1 , wherein the fixed body comprises a plurality of slits formed through the outer circumferential surface of the fixed body and extending parallel to a direction of a rotational axis of the rotating body.

10. The cleaner of claim 9 , wherein the plurality of slits are formed to be inclined with respect to a radial direction of the fixed body.

11. The cleaner of claim 1 , wherein the dust collector further comprises a guide provided on the fixed body to generate a spiral flow between the fixed body and the rotating body.

12. The cleaner of claim 1 , wherein the dust collector further comprises an impeller that is provided to be rotated by the suction force of the fan motor to rotate the rotating body.

13. The cleaner of claim 1 ,
wherein the flow path is a first flow path, and
wherein the dust collector comprises:
a second flow path formed between the rotating body and the housing.

14. The cleaner of claim 1 ,
wherein the dust collecting chamber is a first dust collecting chamber, and
wherein the dust collector comprises:
a second dust collecting chamber formed outside the fixed body.

15. A dust collector comprising:
a housing having an inlet and an outlet;
a fixed body arranged inside the housing;
a rotating body rotatably provided between the housing and the fixed body, and covering an outer circumferential surface of the fixed body;
a flow path formed between the fixed body and the rotating body; and
a driving device provided to generate a driving force for rotating the rotating body,
wherein the fixed body comprises a dust collecting chamber formed inside the fixed body and connected to the inlet of the housing, and
wherein the fixed body is configured so that air inside the dust collecting chamber is discharged to the flow path through the outer circumferential surface of the fixed body.
