Abstract

An air conditioner is provided that may include a main body having an air inlet and an air outlet defined therein; a filter received in the main body to filter air suctioned into the main body; a heat exchanger configured to perform a heat exchange between a refrigerant and the air suctioned into the main body; and an ultraviolet (UV) sterilization module configured to sterilize the air suctioned into the main body. The UV sterilization module may include a porous main body in a mesh form, and a plurality of UV lamps. The porous main body may include a bent portion to allow the porous main body to conform to a shape of the heat exchanger. The main body may include a chassis, and a front frame at a front of the chassis. An inner space may be defined between the chassis and the front frame. The porous main body may be coupled to at least one of the chassis or the front frame, and the plurality of UV lamps may be arranged to be spaced from each other between the air inlet and the heat exchanger.

First claim

What is claimed is:

an ultraviolet (UV) sterilization module configured to sterilize the air suctioned into the main body, wherein the UV sterilization module includes:
a porous main body in a mesh form, wherein the porous main body Includes a photocatalyst coating; and
a plurality of UV lamps, wherein the main body includes a bent portion to allow the porous main body to conform to a shape of the heat exchanger, wherein the plurality of UV lamps is arranged to be spaced from each other between the air Inlet and the heat exchanger, wherein the porous main body is provided upstream of the plurality of UV lamps and the heat exchanger with respect to an airflow direction, and wherein the main body includes:
a chassis; and
a front frame at a front of the chassis, wherein an inner space is defined between the chassis and the front frame, wherein the porous main body is coupled to at least one of the chassis or the front frame, wherein a positional relationship of the porous main body including the photocatalyst coating, the plurality of UV lamps, and the heat exchanger prevents an odorized substance from being attached to the plurality of UV lamps and the heat exchanger, preventing pollution and performance degradation of the plurality of the UV lamps and the heat exchanger.

2. The air conditioner of claim 1 , wherein each of the plurality of UV lamps is an external electrode fluorescent lamp.

3. The air conditioner of claim 1 , wherein the porous main body includes a plurality of first and second holders on first and second sides of the porous main body, respectively, and wherein each of the plurality of UV lamps is coupled to a pair of the first and second holders.

4. The air conditioner of claim 3 , wherein the porous main body includes first and second metal rails on the first and second sides of the porous main body, respectively, and wherein the plurality of first and second holders is provided on the first and second metal rails, respectively.

5. The air conditioner of claim 3 , wherein each of the plurality of first and second holders is shaped to surround one of the plurality of UV lamps.

6. The air conditioner of claim 1 , further including an inverter to supply power to the plurality of UV lamps concurrently.

7. An air conditioner, comprising:
a main body having an air inlet and an air outlet defined therein;
a filter received in the main body to filter air suctioned into the main body;
a heat exchanger configured to perform heat exchange between a refrigerant and the air suctioned into the main body, wherein the heat exchanger has first and second surfaces on different planes;
a mesh member having a first surface that conforms to a shape of the first surface of the heat exchanger and a second surface that conforms to a shape of the second surface of the heat exchanger, wherein the porous main body Includes a photocatalyst coating; and
a plurality of UV lamps supported on the mesh member, wherein a positional relationship of the mesh member including the photocatalyst coating, the plurality of UV lamps, and the heat exchanger prevents an odorized substance from being attached to the plurality of UV lamps and the heat exchanger, preventing pollution and performance degradation of the plurality of the UV lamps and the heat exchanger.

8. The air conditioner of claim 7 , wherein the mesh member includes a plurality of metal holders arranged to be spaced from each other on one surface thereof at a predetermined spacing, and wherein the plurality of UV lamps is coupled to the plurality of the metal holders, respectively.

9. The air conditioner of claim 8 , wherein each of the plurality of metal holders is shaped to surround one of the plurality of UV lamps.

10. The air conditioner of claim 9 , further including an inverter to supply power to the plurality of metal holders concurrently.

11. An air conditioner, comprising
a main body having an air inlet and an air outlet defined therein;
a filter received in the main body to filter air suctioned into the main body;
a heat exchanger configured to perform heat exchange between a refrigerant and the air suctioned into the main body; and
an ultraviolet (UV) sterilization module configured to sterilize the air suctioned into the main body, wherein the UV sterilization module includes a porous lamp support body and a plurality of UV lamps, wherein the plurality of UV lamps is spaced apart and arranged in a parallel manner between the air inlet and the heat exchanger, wherein the porous lamp support body is provided upstream of the plurality of UV lamps and the heat exchanger with respect to an airflow direction, and wherein the porous lamp support body includes a photocatalyst coating, wherein a positional relationship of the porous lamp support body including the photocatalyst coating, the plurality of UV lamps, and the heat exchanger prevents an odorized substance from being attached to the plurality of UV lamps and the heat exchanger, preventing pollution and performance degradation of the plurality of the UV lamps and the heat exchanger.

12. The air conditioner of claim 11 , wherein the porous lamp support body includes first and second metal rails at first and second sides thereof, respectively, and wherein the plurality of UV lamps receives power via the first and second metal rails.

13. The air conditioner of claim 12 , further including a plurality of metal holders provided on each of the first and second metal rails.

14. The air conditioner of claim 13 , wherein the plurality of UV lamps is coupled to the plurality of metal holders, respectively.

15. An air conditioner, comprising
