As shown in fig. 3, the air duct further includes an air passing cavity 133 located on an air outlet side of the purification cavity 132, and an air outlet cavity 134 located on an air outlet side of the heat exchange cavity 131, the air outlet cavity 134 is communicated with the air passing cavity 133 and the air outlet 12, the wind wheel 40 is disposed in the air outlet cavity 134, and the indoor unit of the air conditioner further includes a guide plate 60 disposed in the air passing cavity 133 and used for guiding the air flow from the purification cavity 132 to the air outlet cavity 134. In this embodiment, the air outlet cavity 134 is communicated with the air passing cavity 133, and since the wind wheel 40 is disposed in the air outlet cavity 134 and the air outlet 12 is communicated with the air outlet cavity 134, the air flowing out from the purifying cavity 132 must sequentially pass through the air passing cavity 133 and the air outlet cavity 134 and then flow to the air outlet 12. It can be understood that although the wind wheel 40 is disposed at the air outlet side, the wind wheel 40 still generates negative pressure to the cleaning chamber 132, and thus the wind wheel 40 is still driven to flow from the second air inlet 112 to the air outlet chamber 134 during operation. The guide plate 60 is located in the air passing cavity 133, and the guide surface of the guide plate 60 is inclined to the air outlet direction of the purification cavity 132 and also inclined to the air inlet direction of the air outlet cavity 134, so that the air flow flowing to the air passing cavity 133 can flow to the air outlet cavity 134 more smoothly under the action of the guide plate 60, thereby reducing the loss of air flow and air speed in the air flow turning process and improving the air outlet efficiency. The flow guide surface of the flow guide plate 60 can be a plane or a concave arc surface, so that the turning process of the airflow flowing through the flow guide plate 60 is smoother and more stable.

Because the air guide plate 60 separates the air passing cavity 133 from the air outlet cavity 134 in the temperature adjusting mode, the fan does not generate negative pressure to the air passing cavity 133, and thus, the air flow from the second air inlet 112 can be prevented from influencing the air flow in the temperature adjusting mode; even if the second air inlet 112 is closed by the damper, the partition effect of the baffle 60 can prevent the negative pressure of the fan from making the air passing cavity 133 generate noise, so as to improve the user experience. The baffle 60 may be driven by a third drive means to effect automatic rotation of the baffle 60. By controlling the rotation of the guide plate 60, the guide plate 60 can play an active role in different working modes of the indoor unit of the air conditioner, and the effective utilization rate of the guide plate 60 is improved.
