After the indoor unit 10 of the air conditioner receives the instruction to start cooling, the heat exchange fan is turned on in a controlled manner. Under the action of the heat exchange fan, the air near the air inlet flows through the air inlet and the heat exchange air channel 110 to form heat exchange air, and flows into the indoor space from the air outlet 120 . When the indoor unit 10 of the air conditioner receives the instruction of using indoor air to mix the air, the adjusting part drives the head of the rotating member 222 away from the indoor air inlet 245 to open the indoor air inlet 245, and at the same time, the regulating fan 260 is controlled to open. Under the action of the regulating fan 260, the indoor air flows through the indoor air inlet 245, the indoor air passage and the first air outlet 241 in sequence, and then flows to the vicinity of the air outlet 120, and mixes with the heat exchange air flowing to the air outlet 120. The final airflow is discharged into the indoor space through the air outlet 120.

In the indoor unit 10 of the air conditioner of the present invention, since the airflow adjustment device 200 with a specific structure is added, by regulating the adjustment part of the airflow adjustment device 200, the indoor air or outdoor air can be driven to the air outlet 120 through the first airflow outlet 241. transport, so that indoor air or outdoor air can be mixed with the heat exchange air flowing to the air outlet 120, and the mixed heat exchange air can be blown to the indoor space through the air outlet 120, which enables the air conditioner indoor unit 10 of the present invention to use The streamlined structure improves user comfort, and reduces or avoids air-conditioning sickness or cold caused by the air-conditioning process.

So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used. Many other variations or modifications consistent with the principles of the invention are directly identified or derived from the content. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
