The first fixing part 191 is located on the side of the UV lamp 184 so as not to block the UV light generated by the UV lamp 184 .

The first fixing part 191 is formed in a “L” shape, and the upper end is bent toward the UV lamp 184 .

The second fixing part 192 supports the lower side of the ultraviolet lamp 184 . The second fixing part 192 is formed to protrude upward from the panel body 170 forming the insertion groove 175 .

The ultraviolet lamp 184 is positioned between the first fixing part 191 and the second fixing part 192 .

The UV lamp 184 has an upper end supported by the first fixing unit 191 in a state in which the lower end is supported by the second fixing unit 192 , and is inclined toward the condensed water storage unit 160 .

The ultraviolet rays projected to the condensate storage unit 160 through the window 186 sterilize the condensed water stored in the condensate storage unit 160 as well as sterilize the air passing through the condensate storage unit 160 .

The ultraviolet lamp 184 may sterilize the air that is introduced through the inner surface 165 of the condensed water storage unit 160 and flows through the upper surface 164 .

This is possible because only a portion of the window 186 is submerged in the condensate.
