Abstract

An air-processing apparatus is provided. The air-processing apparatus may include a case having an outlet formed therein, a louver rotatably disposed in the case and configured to adjust a direction of air flowing through the outlet, and a louver actuator configured to adjust an orientation of the louver. The louver may include a louver rotational shaft and a plurality of vanes spaced apart from each other in a radial direction based on the louver rotational shaft. The louver actuator may be disposed so as to be in contact with a vane located at an outermost position among the plurality of vanes to change an orientation of the louver.

First claim

What is claimed is:

1. An air-processing apparatus, comprising:
a case having an outlet formed therein;
a louver assembly rotatably disposed in the case, the louver assembly being configured to adjust a direction of air flowing through the outlet; and
a louver actuator configured to adjust an orientation of the louver assembly, wherein the louver assembly comprises a louver rotational shaft and a plurality of vanes spaced apart from each other in a radial direction based on the louver rotational shaft, and wherein the louver rotational shaft extends along a rotational center of the louver assembly, wherein the plurality of vanes comprises:
an outer vane spaced outwards apart from the louver rotational shaft in the radial direction; and
a plurality of inner vanes disposed between the louver rotational shaft and the outer vane so as to be spaced apart from each other in the radial direction, wherein a vane gear is formed on the outer circumferential surface of the outer vane in a circumferential direction, and wherein the louver actuator is engaged with the vane gear to rotate the louver assembly.

2. The air-processing apparatus according to claim 1 ,
wherein the louver assembly is connected at an outer circumferential surface of the outer vane to the louver actuator.

3. The air-processing apparatus according to claim 2 , wherein the outer vane has an arc shape that extends in a circumferential direction based on the louver rotational shaft.

4. The air-processing apparatus according to claim 2 , wherein the plurality of inner vanes is shorter than the outer vane.

5. The air-processing apparatus according to claim 2 , wherein each of the plurality of inner vanes has a different length from remaining ones of the plurality of inner vanes.

6. The air-processing apparatus according to claim 2 , wherein lengths of the plurality of inner vanes gradually increase in a direction approaching the louver rotational shaft.

7. The air-processing apparatus according to claim 2 , wherein a distance between the outer vane and each of the plurality of inner vanes gradually increases in a downward direction.

8. The air-processing apparatus according to claim 2 , wherein each of the plurality of inner vanes comprises:
a lower inner vane portion inclined so as to be gradually closer to the louver rotational shaft in a downward direction; and
an upper inner vane portion bent and extending upwards from an upper end of the lower inner vane portion.

9. The air-processing apparatus according to claim 2 , wherein the louver assembly comprises an axial vane that extends from the louver rotational shaft, and wherein the axial vane extends in a direction parallel to the lower inner vane portion.

10. The air-processing apparatus according to claim 1 , wherein the louver assembly comprises:
a pair of end panels disposed at both ends of the plurality of vanes in a direction perpendicular to the plurality of vanes; and
a support panel disposed between the pair of end panels, the support panel being provided at one side thereof with a vane gear, and wherein the vane gear is engaged with the louver actuator.

11. The air-processing apparatus according to claim 1 , wherein the louver actuator is spaced apart from the louver rotational shaft in a centrifugal direction, and is disposed so as to be in contact with an outer circumferential surface of the louver assembly.

12. The air-processing apparatus according to claim 1 , wherein the louver actuator comprises:
a louver gear configured to be engaged with one side of the louver assembly to rotate the louver assembly; and
a louver motor configured to rotate the louver gear.

13. The air-processing apparatus according to claim 1 , wherein the louver actuator comprises:
a pair of louver gears spaced apart from each other, the pair of louver gears being engaged with one side of the louver assembly to rotate the louver assembly;
a gear rotational shaft that interconnects the pair of louver gears; and
a louver motor connected to the gear rotational shaft to rotate the gear rotational shaft.

14. The air-processing apparatus according to claim 1 , wherein the case comprises:
an upper cover;
a lower cover disposed below the upper cover;
a rear cover that forms an inlet, the rear cover supporting a filter device mounted thereto; and
a front cover spaced forwards apart from the rear cover, and wherein the louver assembly is rotatably disposed at a lower end of the front cover.

15. The air-processing apparatus according to claim 14 , wherein the front cover includes a louver protrusion having formed therein a louver groove in which the louver rotational shaft is disposed in order to limit a range within which the louver assembly rotates.

16. The air-processing apparatus according to claim 15 , wherein the louver protrusion comprises:
an upper protruding portion forming a surface that is inclined from an upper end of the louver groove in a rearward-upward direction; and
a lower protruding portion forming a surface that is inclined from a lower end of the louver groove in a forward-downward direction.
