And when the air outlet 101 is a plurality of, or the air outlet 101 is bigger, also conveniently increase flexible switch door 20 or adjust the deformation degree of flexible switch door 20 and with the better adaptation of air outlet 101.

It should be noted that, the material of the flexible switch door 20 is not limited in this embodiment, for example, the flexible switch door 20 may be a flexible plastic piece, a rubber piece, a silica gel piece, or a curtain, etc., as long as the flexible switch door 20 can deform to open or close the air outlet 101. In addition, the flexible switch door 20 may be deformed in a rolling or stacking manner.

In this embodiment, the driving assembly 30 is disposed on the casing 10, and preferably, in the case of the operation of the air conditioner indoor unit, the driving assembly 30 is disposed on the top of the casing 10. Thus, when the driving assembly 30 drives the flexible switch door 20 to be curled, the flexible switch door 20 deforms along with the curling, and the air outlet 101 is opened. When the driving assembly 30 drives the flexible switch door 20 to release, the flexible switch door 20 moves downward under the gravity to close the air outlet 101.

Optionally, the housing 10 is configured with a mounting structure 104 at a location where the driving assembly 30 is mounted, and the driving assembly 30 is mounted to the mounting structure 104 of the housing 10.
