The face frame 10 is provided with an air outlet 11, the air outlet 11 is arranged at the lower part of the face frame 10, the indoor air conditioner 100 supplies air towards the indoor through the air outlet 11, the face frame 10 is provided with a first air inlet 12, the first air inlet 12 is arranged at the front side of the face frame 10, and when the indoor air conditioner 100 is opened, air outside the indoor air conditioner 100 can flow into the indoor air conditioner 100 through the first air inlet 12. The front panel 20 is movably arranged on the face frame 10, the front panel 20 can be arranged on the front side of the face frame 10, the front panel 20 can open or close the first air inlet 12, when the front panel 20 closes the first air inlet 12, the face frame 10 and the front panel 20 are matched to form an appearance surface of the indoor air conditioner 100, at the moment, the first air inlet 12 cannot be seen, the indoor air conditioner 100 can be tidier, when the air conditioner works, the front panel 20 is controlled to move to open the first air inlet 12, and air outside the indoor air conditioner 100 flows into the indoor air conditioner 100 through the first air inlet 12. The first driving device 30 is disposed on the face frame 10, and the front panel 20 is connected to the first driving device 30, and the first driving device 30 can drive the front panel 20 to move relative to the face frame 10, so that the front panel 20 opens or closes the first air inlet 12.

The air outlet 11 may be provided with an air deflector 14, the air deflector 14 is rotatably disposed at the air outlet 11, the air deflector 14 may open or close the air outlet 11, when the air conditioner is in standby, that is, when the indoor unit 100 of the air conditioner is not opened, the first driving device 30 drives the front panel 20 to close the first air inlet 12, at this time, the air deflector 14 closes the air outlet 11, the appearance of the indoor unit 100 of the air conditioner is in a fully closed state, so that the appearance of the indoor unit 100 of the air conditioner may be more tidy, and objects such as dust in the indoor environment may be prevented from falling into the indoor unit 100 of the air conditioner from the first air inlet 12, and objects such as dust in the indoor environment may be prevented from entering the indoor unit 100 of the air conditioner from the air outlet 11, so that internal blockage of the indoor unit 100 of the air conditioner may be prevented, and a failure of the indoor unit 100 of the air conditioner may be prevented from being blocked, thereby ensuring usability of the indoor unit 100 of the air conditioner, and also ensuring internal cleanliness of the indoor unit 100 of the air conditioner.

Further, as shown in fig. 2, when the air conditioner is operated, the air conditioning indoor unit 100 is turned on, the first driving device 30 drives the front panel 20 to move so as to open the first air inlet 12, the air guide plate 14 rotates to open the air outlet 11, air in the indoor environment flows into the air conditioning indoor unit 100 from the first air inlet 12, and the air flowing into the air conditioning indoor unit 100 exchanges heat inside the air conditioning indoor unit 100 and is blown out from the air outlet 11.

Therefore, the first air inlet 12 is opened or closed through the front panel 20, when the air-conditioning indoor unit 100 is not opened, the front panel 20 is controlled to close the first air inlet 12, so that objects such as dust in an indoor environment can be prevented from falling into the air-conditioning indoor unit 100 from the first air inlet 12, the internal filth blockage of the air-conditioning indoor unit 100 can be prevented, the service performance of the air-conditioning indoor unit 100 can be ensured, the appearance of the air-conditioning indoor unit 100 can be in a closed state, and the air-conditioning indoor unit 100 can be neater and more integrated.

In some embodiments of the present invention, as shown in fig. 4, the air conditioning indoor unit 100 has a cooling mode, when the air conditioning indoor unit 100 starts the cooling mode, the first driving device 30 is configured to drive the front panel 20 to move below the air outlet 11, and the rear surface of the front panel 20 is formed as the first air guide surface 21. Because of the high density of the cool air, the cool air inside the indoor unit 100 of the air conditioner flows downward quickly after being blown out from the air outlet 11, which may cause the short air supply distance of the indoor unit 100 of the air conditioner, resulting in poor uniformity of temperature drop in the indoor environment. As shown in fig. 4, in the present application, when the air-conditioning indoor unit 100 starts the cooling mode, the first driving device 30 drives the front panel 20 to move below the air outlet 11, at this time, the air deflector 14 opens the air outlet 11, the rear end of the front panel 20 can be overlapped with the lower surface of the front end of the air deflector 14, the inner surface of the front panel 20 is the first air guiding surface 21, the front panel 20 is obliquely extended upward in the direction from the rear end to the front end of the air-conditioning indoor unit 100, and after the cold air in the air-conditioning indoor unit 100 is blown out from the air outlet 11, the cold air can be blown out upward and/or obliquely upward by the first air guiding surface 21, so that the air blowing distance of the air-conditioning indoor unit 100 can be increased, and the uniformity of temperature drop in the indoor environment can be improved.
