The first air outlet 11 faces forward and slopes toward the second air outlet 21 , and the second air outlet 21 faces forward and slopes toward the first air outlet 11 . The above arrangement is beneficial to the mixing of the air when the first air outlet 11 and the second air outlet 21 are simultaneously emitting air, and also increases the coverage area of the outlet air in the height direction, and the coverage area of the outlet air is larger.

In some embodiments of the present invention, the ratio of the lateral width of the second air outlet column 20 to the lateral width of the first air outlet column 10 is less than 1/2. The depth dimension of the second air outlet column 20 along the front and rear direction is the same as the depth dimension of the first air outlet column 10 along the front and rear direction. Viewed from the front of the indoor unit of the vertical air conditioner, the second air outlet column 20 is obviously smaller than the first air outlet column 10. This structure breaks through the routine, is very novel and ingenious, and has a unique appearance and enhances the decorative properties of the home air conditioner. .
