Photocatalyst filter, method for fabricating the same and air cleaner thereof

An electrostatic precipitator, comprising:

• a photocatalyst filter mounted in an air passage of the electrostatic precipitator, wherein the photocatalyst filter comprises:
• a base material of a predetermined shape;
• an enamel layer comprising frit and additives, wherein the enamel layer is coated on a surface of the base material, wherein the frit forms an inorganic layer, and wherein the additives form a porous surface layer;
• and
• a photocatalyst layer comprising a photocatalyst solution and bonding agents, wherein the photocatalyst layer is coated on the enamel layer, wherein the photocatalyst solution comprises a photocatalyst and a dispersion solvent, and wherein the bonding agents mainly comprise SiO2.

An air conditioner, comprising:

• a suction grill on an outer surface of the air conditioner;
• a suction grill cover adjacent to the suction grill;
• an air filter adjacent to the suction grill cover;
• a photocatalyst filter adjacent to the air filter;
• a heat exchanger behind the photocatalyst filter;
• a fan;
• and
• a discharge grill, wherein the photocatalyst filter comprises a base material of a predetermined shape, an enamel layer comprising frit and additives, wherein the enamel layer is coated on a surface of the base material, wherein the frit forms an inorganic layer, and wherein the additives form a porous surface layer, and a photocatalyst layer comprising a photocatalyst solution and bonding agents, wherein the photocatalyst layer is coated on the enamel layer, wherein the photocatalyst solution comprises a photocatalyst and a dispersion solvent, and wherein the bonding agents mainly comprise SiO2.
