The following describes three operation modes of the air conditioning indoor unit with reference to fig. 2 to 7.

The first mode of operation, the heating-normal wind mode.

As shown in fig. 2 and 5, when the air conditioning indoor unit is in the first operation mode, if the normal ventilation area 211 is wound on the first winding shaft 22, the second driving member is controlled to drive the second winding shaft 23 to rotate in the counterclockwise direction so that the rolling screen 21 is gradually wound on the second winding shaft 23, thereby unwinding the normal ventilation area 211 and facing the air outlet 11, the third driving member is controlled to drive the air deflector 5 to rotate upward to a first preset position (e.g., a position parallel to the horizontal direction), and the driving flap 63 of the fourth driving member 62 is controlled to rotate to a second preset position (e.g., a position perpendicular to the air outlet 11), so that a large amount of hot air enters the room.

When the indoor temperature rises to a first preset temperature (for example, 22 ℃), the third driving component is controlled to drive the air deflector to rotate downwards to a third preset position (for example, a position with an included angle of 45 degrees with the horizontal direction), the fourth driving component 62 is controlled to drive the swing blade 63 to swing left and right, so that wind blowing towards the air outlet 11 from the inside of the shell 1 is firstly converted into small breeze through the action of the micropores 213 of the second breeze area 2122, and then is sufficiently disturbed along the left direction and the right direction through the action of the swing blade 63 swinging left and right, and the outlet air of the indoor air conditioner is closer to natural wind.

Of course, after the indoor temperature rises to the first preset temperature, only the third driving member may be controlled to drive the air guiding plate 5 to swing up and down, or the third driving member may be controlled to drive the air guiding plate 5 to swing up and down and the fourth driving member 62 may be controlled to drive the swing blade 63 to swing left and right at the same time, which may be flexibly adjusted and set by a person skilled in the art.

The second mode of operation, the cooling-breeze mode.

As shown in fig. 3 and 6, when the air conditioning indoor unit is in the second operation mode, if the general ventilation area 211 is wound on the first winding shaft 22, the second driving member is controlled to drive the second winding shaft 23 to rotate in the counterclockwise direction so that the rolling curtain 21 is gradually wound on the second winding shaft 23, thereby unfolding the general ventilation area 211 and facing the air outlet 11, the third driving member is controlled to drive the air deflector 5 to rotate upward to the third preset position, and the fourth driving member 62 is controlled to drive the swing blade 63 to rotate to the second preset position, so that a large amount of cold air enters the room, and meanwhile, the cold air is not blown directly towards the human body, thereby achieving rapid cooling of the room.

After the indoor temperature is reduced to a second preset temperature (for example, 27 ℃), if the second breeze area 2122 is wound on the first winding shaft 22, the second driving member is controlled to drive the second winding shaft 23 to rotate in the counterclockwise direction so that the rolling screen 21 is gradually wound on the second winding shaft 23, so that the second breeze area 2122 is unfolded and can shield the air outlet 11, the third driving member is controlled to drive the air deflector 5 to swing up and down, the fourth driving member 62 is controlled to drive the swing blade 63 to swing left and right, so that the air blown from the inside of the casing 1 to the air outlet 11 is first converted into small breeze through the action of the micropores of the second breeze area 2122, and then the small breeze is sufficiently disturbed in the left, right, up and down four directions through the double actions of the swing blade 63 which swings left and right and the air deflector 5 which swings up and down, so that the outlet air of the air conditioner is closer to natural wind.

Of course, after the indoor temperature is reduced to the second preset temperature, only the third driving member may be controlled to drive the air guiding plate 5 to swing up and down, or only the driving swing blade 63 of the fourth driving member 62 may be controlled to swing left and right, and the adjustment and setting may be flexibly performed by those skilled in the art.

And a third mode of operation, a cooling-high breeze mode.

As shown in fig. 4 and 7, when the air conditioning indoor unit is in the third operation mode, if the normal ventilation area 211 is wound on the second winding shaft 23, the first driving member is controlled to drive the first winding shaft 22 to rotate clockwise so that the rolling curtain 21 is gradually wound on the first winding shaft 22, so that the normal ventilation area 211 is unfolded and the air outlet 11 can be shielded, the third driving member is controlled to drive the air deflector 5 to rotate upwards to the third preset position, and the fourth driving member 62 is controlled to drive the swing blade 63 to rotate to the second preset position, so that a large amount of cold air enters the room, and meanwhile, the cold air is not blown directly towards the human body, thereby achieving rapid cooling of the room.

After the indoor temperature is reduced to a third preset temperature (for example, 26 ℃), if the first breeze area 2121 is wound on the second reel 23, the first driving member is controlled to drive the first reel 22 to rotate clockwise so that the roller shutter 21 is gradually wound on the first reel 22, so that the first breeze area 2121 is unfolded and can shield the air outlet 11, the third driving member is controlled to drive the air deflector 5 to swing up and down, the fourth driving member 62 is controlled to drive the swing blade 63 to swing left and right, so that wind blowing from the inside of the casing 1 to the air outlet 11 is firstly converted into large breeze through the action of the micropores of the first breeze area 2121, and then the wind is sufficiently disturbed in the left, right, upper and lower directions through the double actions of the swing blade 63 swinging left and right and the air deflector 5 swinging up and down, so that the outlet air of the air conditioner is closer to natural wind.

Of course, after the indoor temperature is reduced to the third preset temperature, only the third driving member may be controlled to drive the air deflector 5 to swing up and down, or only the driving swing blade 63 of the fourth driving member 62 may be controlled to swing left and right, and those skilled in the art may flexibly adjust and set the temperature.

It should be noted that the first preset position, the second preset position, the third preset position, the first preset temperature, the second preset temperature and the third preset temperature listed in the above three operation modes are only exemplary, but not limiting, and those skilled in the art can flexibly adjust and set the preset positions and the preset temperatures according to actual use requirements in practical applications, and the present invention does not limit this.
