Photocatalyst filter and air conditioner including the same
A photocatalyst filter is provided. The photocatalyst filter includes: a base in which an internal space is formed. The internal space is permeable to fluid, and a plurality of photocatalyst beads are provided in the internal space, wherein a surface of the internal space is reflective.
1. A photocatalyst filter comprising:
a base comprising an internal space which is permeable to a fluid;
a plurality of photocatalyst beads provided within the internal space; and
a cover attached to the base,
wherein a surface of the internal space is reflective, and
wherein the cover includes a photocatalyst material.
2. The photocatalyst filter as claimed in claim 1 , wherein the base further comprises a plurality of reflective walls defining the internal space.
3. The photocatalyst filter as claimed in claim 2 , wherein the plurality of walls are formed of a reflective material.
4. The photocatalyst filter as claimed in claim 3 , wherein the reflective material is one of a metal and a light-reflective resin.
5. The photocatalyst filter as claimed in claim 1 , wherein the plurality of photocatalyst beads comprise a photocatalyst material and an adsorbent.
6. The photocatalyst filter as claimed in claim 5 , wherein the adsorbent is at least one of activated carbon and zeolite.
7. The photocatalyst filter as claimed in claim 1 , wherein the plurality of photocatalyst beads have spherical shapes that are hollow.
8. The photocatalyst filter as claimed in claim 1 , wherein the plurality of photocatalyst beads have protrusions formed on surfaces thereof.
9. The photocatalyst filter as claimed in claim 1 , wherein the cover retains the photocatalyst beads within the internal space.
10. An air conditioner comprising:
a photocatalyst filter comprising a base comprising an internal space through which is permeable to a fluid and a plurality of photocatalyst beads provided within the internal space, wherein a surface of the internal space is reflective;
a fan unit configured to introduce air into the photocatalyst filter;
