The cover plate 6 is connected with the bottom shell 1.

[0053] In this way, the drain groove 3 cooperates with the cover plate 6 to form a drain channel, and the cover plate 6 covers one end of the water collecting groove 2 close to the drain groove 3, which increases the resistance of air entering the air duct where the evaporator 5 is located through the drain port 4, increases the difficulty of air inlet of the air duct at the positions of the water collecting groove 2 and the drain groove 3, reduces the air inlet amount and speed of the air duct, thereby reducing the water bubble in the air duct, and solving the problem that the air duct of the related art vehicle air conditioner is easy to have water bubble.
