Specifically, the casing 10 further includes a front panel 15, the second air inlet 103 is disposed at an upper portion of the front panel 15, the second air door 80 is slidably mounted at an inner side of the front panel 15, and when the second air door 80 moves upward to cover the second air inlet 103, the second air door 80 can allow the indoor air to enter the indoor air duct from the second air inlet 103. When the second air inlet 103 is opened by the downward movement of the second air door 80, the indoor air can enter the indoor air duct through the second air inlet 103, so that the air inlet amount passing through the sterilization assembly 70 can be increased. When the second damper 80 is provided in this manner, it is possible to facilitate user selection. Of course, in other embodiments, the second damper 80 may be provided outside the housing 10 (front panel 15). Further, the second damper 80 may be mounted to the casing 10 in a reversible manner.

In one embodiment, the air conditioner further includes a second motor 90, and the second motor 90 is connected to the second damper 80 to drive the second damper 80 to close or open the second air inlet 103. Specifically, the second motor 90 is electrically connected to an electronic control module on the air conditioner, so that the second damper 80 can be controlled to cover and open the fresh air inlet 105 conveniently. The second motor 90 and the second damper 80 may be connected in various ways, for example, a rack is disposed on the second damper 80, and a gear engaged with the rack is disposed on a rotating shaft of the second motor 90. Or a plurality of transmission teeth are arranged on the second air door 80, and a gear meshed with the transmission teeth is arranged on the rotating shaft of the second motor 90. Or other transmission structures may be used. Of course, in other embodiments, the second motor 90 may not be provided and the second damper 80 may be manually operated.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
