The functional module 40 cooperates with the second air outlet column 20 to at least form the second airflow in the second air outlet column 20 .

Specifically, the first airflow is a heat exchange airflow. "Heat exchange airflow" refers to the airflow that completes heat exchange with the heat exchanger 14 of the air conditioner and is used to adjust the indoor temperature. The heat exchanger 14 is connected with the compressor, the heat exchanger of the outdoor unit, the throttling device and other refrigeration components through pipelines to form a vapor compression refrigeration cycle system. When the indoor unit of the air conditioner is in cooling mode, the heat exchange airflow is cold air.

At the same time, the second air outlet column 20 is rotatable to facilitate the delivery of the second airflow. For example, when there are many requirements for the second airflow, the delivery of the second airflow can be accelerated and the second air outlet column 20 can be rotated at the same time, so that it can be better diffused to various places in the room, and the effect of the functional module 40 can be improved, such as increasing humidification. /Fresh air/dust removal/sterilization/oxygenation and other effects.

Compared with the heat exchange airflow, the temperature of the mixed airflow is closer to the room temperature, with higher comfort and softer wind feeling, which also increases the air volume and wind speed, and the air supply distance is longer. When the wind mixing effect needs to be changed, the second air outlet column 20 can also be rotated about the vertical axis. In this way, the air outlet direction of the second airflow can be changed, as well as the induced air volume, so as to obtain different air outlet effects and more air outlet forms to meet the individual needs of users and improve user experience. Preferably, when the second airflow is a mixed airflow formed by one or more of fresh airflow, purified airflow, humidified airflow, oxygen-adding airflow and water washing airflow and indoor air, that is, when the second air outlet column 20 also blows out indoor air , can achieve a stronger air mixing effect, making the airflow closer to room temperature.
