As described above, the second fresh air member 360 is clamped to the inlet end of the air duct 351 of the first fresh air member 350, and viewed from the direction facing the user, the second fresh air member 360 is located behind the first fresh air member 350, and the rotating shaft of the fresh air rotating plate 340 is disposed at the junction of the first fresh air member 350 and the second fresh air member 360.

The rotation shaft of the fresh air rotating plate 340 is connected with a driving motor, and the driving motor drives the fresh air rotating plate 340 to rotate to open or close the first fresh air inlet 352 and the second fresh air inlet 361.

In this embodiment, the rotation of the fresh air flap 340 has an angular range defined by two extreme positions that the fresh air flap 340 can reach during rotation, namely a first boundary position (denoted as a) and a second boundary position (denoted as B).

When the fresh air rotating plate 340 rotates to the first boundary position, the fresh air rotating plate abuts against the first inner sidewall 336 of the volute cavity, the first fresh air inlet 352 of the first fresh air piece 350 is closed by the fresh air rotating plate 340, and the fresh air released from the volute air outlet 334 cannot enter the first fresh air piece 350 from the first fresh air inlet 352.

Meanwhile, the second fresh air inlet 361 of the second fresh air member 360 is maintained in an opened state, and fresh wind energy released from the scroll exhaust port 334 enters the second fresh air member 360 from the second fresh air inlet 361.

When the fresh air rotating plate 340 rotates to the second boundary position, the fresh air rotating plate and the second inner sidewall 336 of the volute cavity are kept in an open state against the first fresh air inlet 352 of the first fresh air piece 350, and the fresh air energy released from the volute air outlet 334 enters the first fresh air piece 350 from the first fresh air inlet 352.

Meanwhile, the second fresh air inlet 361 of the second fresh air member 360 is closed by the fresh air rotating plate 340, and fresh air released from the volute exhaust outlet 334 cannot enter the second fresh air member 360 from the second fresh air inlet 361.

When the rotation position of the fresh air rotating plate 340 is located between the first boundary and the second boundary, the first fresh air inlet 352 and the second fresh air inlet 361 are both in an open state, and the fresh air energy released from the volute exhaust outlet 334 enters the first fresh air piece 350 from the first fresh air inlet 352 and can enter the second fresh air piece 360 from the second fresh air inlet 361.

In addition, during the rotation of the fresh air rotating plate 340 to the first boundary, the fresh air amount entering the first fresh air inlet 352 from the scroll air outlet 334 decreases, and the fresh air amount entering the second fresh air inlet 361 from the scroll air outlet 334 increases.

And, in the process of the fresh air rotating plate 340 rotating toward the second boundary, the fresh air quantity entering the first fresh air inlet 352 from the volute air outlet 334 increases, and at the same time, the fresh air quantity entering the second fresh air inlet 361 from the volute air outlet 334 decreases.

The fresh air flap 340 may be continuously rotatable between a first boundary and a second boundary.

The air conditioner operates, and the heat exchange module 300 and the fresh air module 300 can be started at the same time.

The heat exchange module 300 operates, the heat exchange fan 220 is started, indoor air enters the indoor unit from the heat exchange air inlet 230, heat exchange is carried out between the heat exchange module 300 and the indoor unit of the air conditioner, and finally the indoor air is released to the room from the heat exchange air outlet 240.

The fresh air module 300 operates, the fresh air fan 320 is started, the motor drives the fresh air fan 320 to rotate to generate wind suction force, outdoor air enters the fresh air pipe from the outdoor end of the fresh air pipe and flows through the fresh air chamber, enters the volute 330 through the filtration of the filter 313, enters the first fresh air piece 350 and/or the second fresh air piece 360 from the volute 330 and is released into a room from the first fresh air outlet 120 and/or the second fresh air outlet 120.

Since the first fresh air outlet 120 is above the heat exchange air outlet 240 and is next to the heat exchange air outlet 240, the fresh air released from the first fresh air outlet 120 and the air released from the heat exchange air outlet 240 can be mixed when released, and heat exchange occurs, so that the temperature of the fresh air entering the room from the first fresh air outlet 120 and the indoor temperature difference are reduced, and the problem of the temperature difference of the fresh air and the cold and hot air is alleviated.

The second fresh air outlet 120 is disposed at one side of the heat exchange air outlet 240, and the heat exchange air outlet 240 and the second fresh air outlet 120 share one air deflector 110, so that the direction of the fresh air released from the second fresh air outlet 120 can be adjusted by the air deflector 110.

The first air outlet windows 357 on the first fresh air member 350 are arranged at intervals, so that fresh air released from the first fresh air member 350 into a room meets heat exchange air in a form of interval air outlet, and compared with continuous arrangement of the air outlet windows, the mode can increase air mixing efficiency of the fresh air and the heat exchange air.

The fresh air rotating plate 340 continuously rotates in a certain range, and can accurately adjust the fresh air volume entering the first fresh air inlet 352 and the second fresh air inlet 361 from the volute air outlet 334, and accurately adjust the fresh air volume released indoors from the first fresh air outlet 120 and the second fresh air outlet 120.

Compare in side or the higher authority of indoor set with the air outlet setting of new trend, set up first new wind air outlet 120 and second new trend air outlet 120 in the front side of air conditioning indoor set, make things convenient for the user to directly see the situation of air outlet operation and directly feel new trend, promote user experience.
