When the speed of the airflow at the tongue root 210 of the volute tongue 200 in the air duct is too high or too low, noise is easily caused, and the quality of the outlet air of the indoor unit of the air conditioner is reduced. When the linear velocity of the outer edge of the wind wheel 300 is greater than 1.5 times of the air flow velocity at the tongue root 210 under the rated power of the indoor unit of the air conditioner, it indicates that the velocity of the air flow at the tongue root 210 is too high, and noise is easily generated, so that the first included angle beta is set to be greater than the second included angle alpha, and the air passing duct can play a role in buffering the air flow so as to reduce the air flow velocity at the tongue root 210 of the volute tongue 200, so that the air flow velocity at the tongue root 210 tends to be normal, and the sound quality can be improved.

Note that the front section 241 of the air duct 240 is disposed between two adjacent bent portions 231, and the rear section 242 of the air duct 240 is disposed between two adjacent rear portions 232. The windward side of the bent portion 231 abuts against the surface of the diffuser section 220 located in the air duct. Because the tongue root 210 of the volute tongue 200 and the diffusion section 220 form an included angle, the windward surface of the bending part 231 is arc-shaped, which is beneficial to smooth transition of air flow from the tongue root 210 to the diffusion section 220, and also can reduce noise generated when air flow flows from the tongue root 210 to the diffusion section 220, and is beneficial to noise reduction and tone quality improvement.

Due to the change of the radian of the windward side, the wind guiding effect of the windward side is changed, and the height of the air channel at the windward side of the bent part 231 is changed, so that the air flow at the windward side of the bent part 231 is changed, resonance is destroyed, squeal is eliminated, and the air outlet tone quality of the indoor unit of the air conditioner is improved.
Specifically, the bent portions 231 on the tongue root 210 in this embodiment may have different radians of all the bent portions 231, and have the characteristics of large air volume difference and many changes on the tongue root 210, and have the characteristic of good howling elimination effect; the radian of some of the bent portions 231 may be the same, and the radian of the other bent portion 231 may be different; the radians of two adjacent bending portions 231 are different, so that the effects of eliminating squeal and improving sound quality can be achieved.

The windward side of the rear portion 232 is a slope, which facilitates smooth variation of the airflow on the rear portion 232 and smooth guiding of the airflow to the diffuser section 220.
Further, in the present embodiment, as shown in fig. 8, the length of the bending part 231 is smaller than that of the rear part 232. Because the wind speed at the tongue root 210 of the volute tongue 200 is high, if the airflow flow or the wind direction change too much, the stability of the airflow in the air duct is damaged. The rear portion 232 has a longer length, so that the rear portion 232 of the tooth protrusion 230 has a longer distance for changing the air flow, which is beneficial to ensuring the stable air flow on the tooth protrusion 230. Because the function of the portion 231 of bending turns to for worker's air current, the length of the portion 231 of bending is shorter also can effectively guide the air current to rotate, does not influence the function of the portion 231 of bending.
