Abstract

A disclosed embodiment provides a clothes care device which can improve service life, is not influenced by humidity, and can resolve odor problems. A clothes care device, according to one aspect of the present invention, comprises: an air blower; a flow path through which air, which is made to flow by the air blower, moves; and a deodorizing module for purifying the air which is made to flow by the air blower. The deodorizing module comprises: a ceramic filter provided inside the flow path; and an ultraviolet light emitting unit provided on the outside of the flow path so as to face the ceramic filter.

First claim

The invention claimed is:

1. A clothes care apparatus comprising:
a blower to cause air to flow;
a flow path through which the air caused to flow by the blower moves; and
a deodorization module configured to purify the air caused to flow by the blower,
wherein
the deodorization module includes:
a ceramic filter provided inside the flow path, and
an ultraviolet light emitter outside of the flow path and facing the ceramic filter, and configured to emit ultraviolet light having an intensity corresponding to a current that is applied to the ultraviolet light emitter and that is adjustable in accordance with an intensity of air volume caused to flow by the blower,

the ceramic filter includes a base material and a catalyst applied on a surface of the base material,
a density of the base material is 0.5 g/ml to 3.0 g/ml and a moisture content of the base material is 5% or less,
the catalyst includes a photocatalyst or a thermal catalyst, and
the deodorization module is configured so that a flow rate of air passing through the ceramic filter is adjustable to 0.5 to 3.0 m/see to obtain a catalytic efficiency being 80% or more.

2. The clothes care apparatus of claim 1 , wherein the deodorization module further includes:
a supporter configured to support the ultraviolet light emitter so that the ultraviolet light emitter is spaced apart from the ceramic filter by a predetermined distance.

3. The clothes care apparatus of claim 2 , wherein the supporter is formed of at least one material of Poly(methyl methacrylate), polycarbonate, glass, and aluminum.

4. The clothes care apparatus of claim 2 , wherein the supporter has a thickness of 1 to 2 mm.

5. The clothes care apparatus of claim 1 , wherein
the base material is formed of at least one of cordierite and mullite.

6. The clothes care apparatus of claim 5 , wherein the catalyst consists of at least one of titanium oxide (TiO2), tungsten oxide (WO3), zinc oxide (ZnO), manganese dioxide (MnO2), or titanium tetraisopropoxide (TTIP).

7. The clothes care apparatus of claim 5 , wherein the catalyst consists of at least one metal of Mn, Cu, Co, Pt, and Au.

8. The clothes care apparatus of claim 5 , wherein the base material is formed in a honey-comb type having 100 to 300 pixels per inch.

9. The clothes care apparatus of claim 5 , wherein the base material is formed in a porous foam type having 15 to 20 pixels per inch.

10. The clothes care apparatus of claim 1 , wherein a distance between the ceramic filter and the ultraviolet light emitter is 10 mm or more and 25 mm or less.

11. The clothes care apparatus of claim 1 , wherein a thickness of the ceramic filter is 5 mm or more and 15 mm or less.

12. The clothes care apparatus of claim 1 , wherein the ultraviolet light emitter is configured so that the current applied to the ultraviolet light emitter is adjustable in a range from 50 to 200 mA.

13. The clothes care apparatus of claim 1 , wherein the ultraviolet light emitter is configured so that an operation time of the ultraviolet light emitter is adjustable in a range from 10 to 60 minutes.

14. The clothes care apparatus of claim 1 , wherein the ultraviolet light emitter is configured so that, in response to a second mode in which an intensity of air volume caused to flow by the blower is stronger than an intensity of air volume caused to flow by the blower in a first mode, the current applied to the ultraviolet light emitter is increased to be greater than the current applied to the ultraviolet light emitter in the first mode.

15. The clothes care apparatus of claim 1 , wherein the ultraviolet light emitter is configured so that the current applied to the ultraviolet light emitter is adjustable in accordance with a temperature of air caused to flow by the blower to secure life and reliability of the ultraviolet light emitter.

16. The clothes care apparatus of claim 1 , wherein the ultraviolet light emitter is configured so that the current applied to the ultraviolet light emitter is blocked in response to a temperature of air cause to flow by the blower being higher than 70° C.

17. The clothes care apparatus of claim 1 , wherein the deodorization module further includes:
a dust collecting filter at a front end of the ceramic filter.
