When the absolute value of the difference is greater than or equal to the first preset value and less than the second preset value, each wind guide column 180 rotates to a position extending along the front and rear directions; In the air volume aggregation and uniform wind mode, the effective air outlet area of the outlet of the uniform air outlet 140 becomes larger, the air volume becomes larger, the air supply distance is longer, and the heat exchange speed of the room is fast, which is suitable for rapid heat exchange scenarios;

When the absolute value of the difference is greater than or equal to the second preset value, the front end of each wind guiding post 180 is rotated to a position close to the partition 190, preferably, each of the wind guiding posts is rotated to be in contact with the partition The position where the front end of the side facing the wind guide column contacts. At this time, the indoor unit 100 of the vertical air conditioner is in the clustered air supply mode with large air volume, basically no passive air uniformity, large air volume and low air temperature, and is suitable for scenes where the indoor temperature is high and rapid cooling is required. For example, the first preset value is 1°C, and the second preset value is 3°C.
