As shown in FIG. 1 and FIG. 2 , the air conditioner in this embodiment is specifically an air conditioner indoor unit, including: a casing 10 , a fan housed in the casing 10 , and a heat exchanger 40 .

Specifically, the fan in the air conditioner is accommodated in the housing 10, including a motor 31 as a driving device and a fan blade structure. Driven by the driving device, the fan blade structure can make air enter along the radial direction of the fan blade structure and move along the direction of the fan blade structure. The axial direction of the fan blade structure is sent out; the heat exchanger 40 is arranged between the casing 10 and the fan, and is used to exchange heat for the air passing through the air conditioner; wherein, the casing 10 includes a The panel 11, and the side plate 13 arranged in the circumferential direction of the blower fan, the panel 11 and the side plate 13 are provided with ventilation holes 15, and then the air is moved along the radial direction of the fan blade structure by setting the fan blade structure in the air conditioner. Enter and send out along the axial direction of the fan blade structure, so that the air conditioner can set up ventilation holes 15 on the panel 11 and side plate 13 for air outlet and air intake, and the setting of the ventilation holes 15 is not affected by the arrangement of the internal parts of the air conditioner. Affected by other factors, the ventilation holes 15 can be covered as much as possible on the panel 11 and the side panel 13 of the air conditioner, thereby increasing the area size of the air inlet and the air outlet, improving the circulation of the air volume, while the ventilation holes on the panel 11 15 can disperse the wind force and improve the comfort of the wind.

Since the setting of the ventilation hole 15 in the present embodiment will not be affected by the internal parts of the air conditioner, it can be set and arranged freely. The number of the ventilation holes 15 is preferably multiple, specifically micropores with smaller apertures, evenly distributed in the air conditioner. The side panels 13 and the panel 11 are respectively used for the air inlet and outlet of the air conditioner, which can further improve the uniformity of the air outlet and the comfort of the air outlet.
