AI Technical Summary
In existing air conditioners, the worm tongue groove of the air duct volute will cause the airflow to collide with the worm tongue, causing a sudden sound.
Install anti-projection sound parts in the length direction of the air duct volute to seal the open opening of the snail tongue groove to reduce airflow into the snail tongue groove.
It effectively reduces the protruding sound caused by airflow collide with the snail tongue inside the groove of the snail tongue, and improves the user experience.
