Air conditioner air supply structure, air conditioner and control method of air conditioner

The invention relates to an air conditioner air supply structure, an air conditioner with the air supply structure and a control method of the air conditioner. The air conditioner air supply structure comprises an air outlet and an air flue arranged in the longitudinal direction of the air conditioner. The air flue comprises at least two airflow channels. An upper end airflow channel is arranged between the air flue and the air outlet. An airflow flow direction adjusting device is arranged in the upper end airflow channel and used for adjusting the flow direction of airflow blown out of the at least two airflow channels. In the air conditioner air supply structure, the airflow flow direction adjusting device capable of adjusting the airflow flow direction is arranged in the upper end airflow channel, the airflow flow direction can be adjusted when the air conditioner is in different work modes, and when the air conditioner is in a heating mode, hot air can be blown downwards accordingly. When the air conditioner is in a refrigerating mode, cold air can be blown upwards, the application comfort level of the air conditioner is improved, and an even temperature field can be formed indoors easily.
