In the present application, the minimum wind speed of the air conditioner is reduced as much as possible under the condition that the air pressure at the air outlet, which is the air outlet, is maintained constant, thereby ensuring that the noise value at the air outlet is low.
Alternatively, the plenum 20 is pivotally or slidably connected to the duct walls of the duct 11. Thus, the booster 20 is moved into the air duct 11 in a rotating manner, or the booster 20 is moved into the air duct 11 in a sliding manner, so that the movement reliability of the booster 20 is ensured, and the difficulty in processing and manufacturing the indoor unit is reduced.
It should be noted that, in the present application, in order to avoid that the flow area of the air duct 11 is zero when the pressure increasing portion 20 moves into the air duct 11, it is preferable that at least a part of the pressure increasing portion 20 is not in contact with the air duct wall of the air duct 11 when the pressure increasing portion 20 is located at the pressure increasing position, so that the flow area is not zero. Therefore, the phenomenon that the air duct 11 is not communicated with the air port due to the fact that the flow area of the air duct 11 is zero is avoided, and the air outlet reliability of the air port serving as the air outlet is ensured.

Note that, in the present application, in order to avoid the pressure increasing plate 21 occupying the space of the air path 11 when in the initial position, it is preferable that the pressure increasing plate 21 be moved to be flush with the extending direction of the air path wall on the side where the pressure increasing plate 21 is located when in the initial position. Thus, it is ensured that the air inlet amount of the tuyere as the air inlet is sufficiently large.
It should be noted that, in the present application, in order to ensure that the flow area of the air duct 11 can be effectively reduced when the pressure increasing plate 21 is located at the pressure increasing position, it is preferable that the pressure increasing plate 21 has a deflection angle with the air duct wall on the side thereof when the pressure increasing plate 21 is rotated toward the air duct 11 to the pressure increasing position.
