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

1 . A clothes care apparatus comprising:
a blower; a flow path through which air flowing by the blower moves; and a deodorization module configured to purify air flowing by the blower, wherein the deodorization module comprises a ceramic filter provided inside the flow path; and an ultraviolet light emitter provided on an outside of the flow path to face the ceramic filter.

2 . The clothes care apparatus of claim 1 , wherein
the deodorization module further comprises a supporter configured to support the ultraviolet light emitter to be 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, FR4, 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 ceramic filter comprises a base material formed of at least one of cordierite and mullite; and a catalyst applied on a surface of the base material.

6 . The clothes care apparatus of claim 5 , wherein
the catalyst comprises at least one of titanium oxide (TiO 2 ), tungsten oxide (WO 3 ), zinc oxide (ZnO), manganese dioxide (MnO 2 ), or titanium tetraisopropoxide (TTIP).

7 . The clothes care apparatus of claim 5 , wherein
the catalyst comprises 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 number of cells of the ceramic filter is 200 or more and 800 or less.

13 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to adjust a current applied to the ultraviolet light emitter to a range from 50 to 200 mA.

14 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to adjust an operation time of the ultraviolet light emitter to a range of from 10 to 60 minutes.

15 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to adjust a current applied to the ultraviolet light emitter in accordance with an intensity of air volume of the blower.

16 . The clothes care apparatus of claim 1 , further comprising:
a controller, in response to a second mode in which an intensity of air volume of the blower is stronger than a first mode, configured to increase a current value, which is applied to the ultraviolet light emitter, to a second current value greater than a first current value corresponding to the first mode.

17 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to adjust a current applied to the ultraviolet light emitter in accordance with a temperature of air introduced by the blower.

18 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to block a current applied to the ultraviolet light emitter in response to a temperature of air introduced by the blower being higher than 70° C.

19 . The clothes care apparatus of claim 1 , further comprising:
a controller configured to adjust a flow rate of air passing through the ceramic filter to 0.5 to 3.0 m/sec.

20 . The clothes care apparatus of claim 1 , wherein
the deodorization module further comprises a dust collecting filter provided at a front end of the ceramic filter.
