Further, the method comprises the following steps: the indoor unit has a second human sensing mode. When the indoor unit starts the second human sensing mode, the sensor 9 is controlled to be in a working state, and the current position of the target object is detected according to the sensor 9. When the sensor 9 detects that the current position of the target object is located on the same side of the second air deflector 6, the first air deflector 5 is controlled to be located at a first open position, the second air deflector 6 is controlled to be located at a second closed position, and the third air deflector 7 is controlled to be located at a third open position.

Through the control, the indoor unit can realize independent upward air outlet to realize a common refrigeration mode, independent air outlet to realize a common heating mode, and meanwhile, the indoor unit can also realize the refrigeration and heating modes of upward and downward simultaneous air outlet.

As shown in fig. 3, in the normal cooling mode, the second air deflector 6 and the third air deflector 7 are not moved, the first air deflector 5 is rotated to open a certain angle, and cold air flows are blown upwards, so that shower cooling is realized.

As shown in fig. 6, which is a normal heating mode of the indoor unit, the first air deflector 5 is not moved, the second air deflector 6 and the third air deflector 7 are rotated and opened to a certain angle, and hot air flows downward to realize carpet heating.

In an exemplary embodiment, as shown in fig. 8 and 9, the second wind guiding plate 6 and the third wind guiding plate 7 may be respectively located at two different positions, that is, the second wind guiding plate 6 located at the left side of the casing 1 is kept still, the third wind guiding plate 7 located at the right side of the casing 1 is rotated and opened to a certain angle, and then the third wind guiding plate 7 is opened to a certain angle in cooperation with the first wind guiding plate 5. In this mode, the indoor unit realizes that the air current blows upwards on the side (left side) of the second air deflector 6, and the air current blows downwards on the side (right side) of the third air deflector 7, so that the indoor unit can realize the simultaneous air-out from the top and the bottom no matter the air conditioner is in the refrigeration or heating mode, and the air in the whole room is more uniform.

In an exemplary embodiment, as shown in fig. 4 and 5, the two small air deflectors are respectively in two different states, that is, the third air deflector 7 located on the right side of the casing 1 remains still, the second air deflector 6 located on the left side of the casing 1 rotates to open to a certain angle, and then opens to a certain angle in cooperation with the first air deflector 5. In this mode, the indoor unit blows air upward on the side (right side) of the third air deflector 7, and blows air downward on the side (left side) of the second air deflector 6. Furthermore, two upper and lower common air outlet modes realized by the indoor unit can improve the uniformity of the air organization of the whole room, and can also realize the partitioned air supply modes of different left and right areas, thereby improving the comfort experience of users.

Further, as shown in fig. 1, a human detection sensor is provided in the middle of the air conditioner, and the sensor 9 divides the room into two areas (area a and area B) approximately with the middle of the air conditioner as a boundary. When the indoor unit is in a cooling or heating mode, and the temperature of a human body in a corresponding area is detected by the sensor 9, the indoor unit can automatically adjust the combination of the positions of the second air deflector 6, the third air deflector 7 and the first air deflector 5, so that the air supply effect of 'people following by wind' or 'people avoiding by wind' is realized. The indoor unit can realize the effect of partitioned air supply by adopting one fan blade, and the comfort experience of users is further improved. A specific control method of the indoor unit is shown in fig. 10 and 11.

In an alternative embodiment, the first air guiding plate 5 may also be split into two air guiding plates capable of being independently driven in the left-right direction, for example, the two air guiding plates may be split into a left air guiding plate and a right air guiding plate, and the two air guiding plates may be combined with the second air guiding plate 6 and the third air guiding plate 7 in various ways to realize different air supply modes in the two cooling and heating modes.
