The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the scope of the present invention.
As shown in fig. 1, in an exemplary embodiment of the indoor unit provided by the present invention, the indoor unit includes a first air duct 10 and a first air deflector 20, the first air deflector 20 is disposed in the first air duct 10, and the first air deflector 20 is rotatable with respect to the first air duct 10 to adjust a ventilation area of the first air duct 10.
In this embodiment, the rotatable first air deflector 20 is disposed in the first air duct 10, and the ventilation area of the first air duct 10 can be adjusted by rotating the first air deflector 20, so as to solve the problems of abnormal air intake or air outlet, fan wheezing or small air volume caused by small air opening area in the prior art.
In this embodiment, the first air deflection 20 is made of a hard material, and the shape of the first air deflection 20 does not change during rotation.
Alternatively, the first air duct 10 may be an air inlet duct or an air outlet duct.

Of course, in other embodiments, other components may be employed to mount the first shaft 130 and the second shaft 140.
Alternatively, the third air deflector 120 and the drip tray 60 may serve as the above-described stoppers. Specifically, the third air deflector 120 is configured to limit the rotation angle of the first segment 21, and the water pan 60 is provided with a protrusion for limiting the rotation angle of the second segment 22.
The indoor unit may further include a second air duct 70 and a second air guide plate 80, the second air guide plate 80 being disposed in the second air duct 70, and the second air guide plate 80 being rotatable with respect to the second air duct 70 to adjust a ventilation area of the second air duct 70. The second air duct 70 may be used as an air intake duct or an air outlet duct.
