[0042] In some embodiments, the first air deflector 200 also has a first air guide limit position and a second air guide limit position, the second air guide limit position is located between the first air guide limit position and the first closed position, and the first air deflector 200 is arranged to be able to reciprocate between the first air guide limit position and the second air guide limit position (for reference Figures 14-16 For understanding). Wherein, based on the first air deflector 200 reciprocating between the first air guide limit position and the second air guide limit position, the second matching end 220 is located at the upper rear side of the first matching end 210. The angle between the first air guide limit position and the second air guide limit position can be set to be not greater than 60 degrees.

[0043] In some embodiments, as shown in Figure 3 , Figure 8 and Figure 16 , the first sub-air deflector 310 has a fourth closed position, and the rotation axis of the fifth matching end 321 in the front-rear direction is located at the rear side of the rotation axis of the third matching end 311. The second sub-air deflector 320 also has a seventh open position. Wherein, as shown in Figure 3 , Figure 8 and Figure 16 , based on the first sub-air deflector 310 being located at the fourth closed position and the second sub-air deflector 320 being located at the seventh open position, the sixth matching end 322 is located above the fifth matching end 321 and abuts against the rear side of the first sub-air deflector 310. At this time, the air conditioner indoor unit blows air from the second air outlet section 118 and / or the lower air outlet 120, and the air beam blown in the machine body 100 will not produce wind noise between the first sub-air deflector 310 and the second sub-air deflector 320. Therefore, the air noise generated during the operation of the air conditioner indoor unit is smaller, and the air outlet effect of the air conditioner indoor unit is better.

[0044] In some embodiments, as shown in Figure 2 , Figure 17As shown, based on the first sub-air baffle 310 being located at the fourth closed position and the second sub-air baffle 320 being located at the sixth closed position, the fourth matching end 312 is located at the lower side of the third matching end 311 and the sixth matching end 322 is located at the lower side of the fifth matching end 321, the fourth matching end 312 is forwardly sealed and lapped on the fifth matching end 321, and the lapped size is not less than 5 mm.

[0045] In some embodiments, as shown in Figure 4 , Figure 6 , Figure 7 , Figures 9-11 , Figures 13-15 As shown, the first sub-air baffle 310 further has a fourth open position, based on the first sub-air baffle 310 being located at the fourth open position, the fourth matching end 312 is located at the rear side of the third matching end 311 and abuts upwardly on the upper side wall of the body 100. Wherein, the included angle between the fourth closed position and the fourth open position is 90 degrees to 135 degrees.

[0046] In some embodiments, as shown in Figure 6 and Figure 14 The projection of the rotation axis of the first sub-air baffle 310 and the rotation axis of the second sub-air baffle 320 in the front-rear direction coincides, the second sub-air baffle 320 further has an eighth open position, based on the first sub-air baffle 310 being located at the fourth open position and the second sub-air baffle 320 being located at the eighth open position, the fourth matching end 312 is located at the rear side of the third matching end 311 and abuts upwardly on the upper side wall of the body 100, the sixth matching end 322 is located at the upper side of the fifth matching end 321, and the front side of the second sub-air baffle 320 (i.e. the side of the second sub-air baffle 320 facing forward at this time) covers the first air outlet section 117 forwardly (at this time, the second air outlet section 118 and / or the lower air outlet 120 of the air conditioner indoor unit are opened). In this scheme, when the first sub-air baffle 310 is located at the fourth open position, the second sub-air baffle 320 can be swung to the eighth open position, and when the first sub-air baffle 310 is located at the fourth closed position, the second sub-air baffle 320 cannot be swung to the eighth open position. Wherein, the included angle between the sixth closed position and the eighth open position is 170 degrees to 180 degrees.

[0047] In other embodiments, as shown in Figure 3 , Figure 8 and Figure 16As shown, the rotation axis of the second sub-air baffle 320 is located at the rear side of the rotation axis of the first sub-air baffle 310 in the front-rear direction, and the second sub-air baffle 320 further has an eighth open position. Based on the first sub-air baffle 310 being located at the fourth closed position and the second sub-air baffle 320 being located at the eighth open position, the first sub-air baffle 310 closes the first air outlet section 117, and the sixth matching end 322 is located at the upper side of the fifth matching end 321 and abuts against the rear side of the first sub-air baffle 310. In this scheme, when the first sub-air baffle 310 is located at the fourth closed position, the second sub-air baffle 320 can swing to the eighth open position, and when the first sub-air baffle 310 is located at the fourth open position, the second sub-air baffle 320 can also swing to the eighth open position. The included angle between the sixth closed position and the eighth open position is 170 degrees to 180 degrees.

[0048] In some examples, as shown in Figure 17 As shown, the first air baffle 200, the first sub-air baffle 310, and the second sub-air baffle 320 all include arc-shaped plate sections.

The concave sides of the arc-shaped plate sections of the first sub-air baffle 310 and the second sub-air baffle 320 all face rearward, and the convex curved sides all face forward.

[0049] In some examples, as shown in Figures 1-17 As shown, the rear part of the lower side wall of the body 100 has an air return outlet 130, the width A of the air return outlet 130 in the front-rear direction is greater than the width D of the front air outlet 110 in the up-down direction, and the width C of the lower air outlet 120 in the front-rear direction, so that the air inlet amount of the air return outlet can better meet the air outlet amounts of the front air outlet and the lower air outlet, and the air outlet proportions of the front air outlet and the lower air outlet are optimized, which is conducive to improving the operation performance of the air conditioner indoor unit. A can be 3C to 4C.

[0051] In some embodiments, as shown in Figure 15 As shown, the size of the first air outlet section 117 in the up-down direction is P, and P is less than C, so that when the first air outlet section 117 and the lower air outlet 120 are opened and the second air outlet section 118 is closed, the airflow blown by the air conditioner indoor unit can be quickly landed on the ground. P can be set to 40mm to 46mm, and C can be set to 54mm to 60mm.

It can be that the appearance surface 540 includes a convex curved surface, the curved plate segment includes the convex curved surface, and the overlapping surface 530 includes a straight surface or a curved surface. The sealing and closing described in this application do not mean absolute sealing and absolute closing state, and due to factors such as manufacturing error and installation error, there may be a slight air leakage problem at the sealing position and the closing position.

[0063] In some examples, based on the first wind plate 200 opening the lower air outlet 120 and the second sub-wind plate 320 closing the second air outlet section 118, before controlling the second sub-wind plate 320 to open the second air outlet section 118, the step of controlling the first wind plate 200 to close the lower air outlet 120 comprises: based on the first wind plate 200 opening the lower air outlet 120, the first sub-wind plate 310 opening the first air outlet section 117, and the second sub-wind plate 320 closing the second air outlet section 118 (such as Figure 11If the first air baffle 200 opens the lower air outlet 120 and the second sub-air baffle 320 closes the second air outlet section 118, then before controlling the second sub-air baffle 320 to open the second air outlet section 118, the first air baffle 200 is controlled to close the lower air outlet 120 first, and then the second sub-air baffle 320 opens the second air outlet section 118, at this time, the first air outlet section 117 and the second air outlet section 118 are in an open state, and the lower air outlet 120 is in a closed state. After the second sub-air baffle 320 opens the second air outlet section 118, the first air baffle 200 is controlled to open the lower air outlet 120, so that the lower air outlet 120 is also in an open state (of course, the first air baffle 200 can also not be controlled to open the lower air outlet 120).

[0064] In other examples, based on the first air baffle 200 opening the lower air outlet 120 and the second sub-air baffle 320 closing the second air outlet section 118, the step of controlling the first air baffle 200 to close the lower air outlet 120 before controlling the second sub-air baffle 320 to open the second air outlet section 118 includes: based on the first air baffle 200 opening the lower air outlet 120, the first sub-air baffle 310 closing the second air outlet section 118, and the second sub-air baffle 320 closing the second air outlet section 118 (as shown in FIG. 6B), the first air baffle 200 is controlled to close the lower air outlet 120 before the second sub-air baffle 320 is controlled to open the second air outlet section 118. Figure 1 and Figure 2 If the first air baffle 200 opens the lower air outlet 120 and the second sub-air baffle 320 closes the second air outlet section 118, then before controlling the second sub-air baffle 320 to open the second air outlet section 118, the first air baffle 200 is controlled to close the lower air outlet 120 first, and then the second sub-air baffle 320 opens the second air outlet section 118, at this time, the first air outlet section 117 and the second air outlet section 118 are in an open state, and the lower air outlet 120 is in a closed state. After the second sub-air baffle 320 opens the second air outlet section 118, the first air baffle 200 is controlled to open the lower air outlet 120, so that the lower air outlet 120 is also in an open state (of course, the first air baffle 200 can also not be controlled to open the lower air outlet 120).

[0065] In other examples, based on the first air baffle 200 opening the lower air baffle 120 and the second sub-air baffle 320 closing the second air outlet section 118, the step of controlling the first air baffle 200 to close the lower air outlet 120 before controlling the second sub-air baffle 320 to open the second air outlet section 118 includes: based on the first air baffle 200 opening the lower air outlet 120, the first sub-air baffle 310 closing the second air outlet section 118, and the second sub-air baffle 320 closing the second air outlet section 118 (as shown in FIG. 6B), the first air baffle 200 is controlled to close the lower air outlet 120 before the second sub-air baffle 320 is controlled to open the second air outlet section 118. Figure 1 and Figure 2As shown in the diagram, before controlling the second sub-air vane 320 to open the second air outlet section 118, the first air vane 200 is first controlled to close the lower air outlet 120. When controlling the second sub-air vane 320 to open the second air outlet section 118, the first sub-air vane 310 is simultaneously controlled to open the first air outlet section 117. At this time, the second air outlet section 118 is in the open state, and the lower air outlet 120 is in the closed state. The first air outlet section 117 may be in the open state or may be in the closed state by the second sub-air vane 320. After the second sub-air vane 320 opens the second air outlet section 118, the first air vane 200 is then controlled to open the lower air outlet 120, so that the lower air outlet 120 is also in the open state (of course, it is also possible not to control the first air vane 200 to open the lower air outlet 120).

This allows the first sub-air vane 310 to avoid the movement trajectory of the second sub-air vane 320, preventing the first sub-air vane 310 from affecting the normal opening of the second sub-air vane 320. At this time, the second air outlet section 118 is in the open state, the lower air outlet 120 is in the closed state, and the first air outlet section 117 may be in the open state or may be in the closed state by the second sub-air vane 320. After the second sub-air vane 320 opens the second air outlet section 118, the first air vane 200 is then controlled to open the lower air outlet 120, so that the lower air outlet 120 is also in the open state (of course, it is also possible not to control the first air vane 200 to open the lower air outlet 120).

[0067] In some examples, the control method also includes: closing the lower air outlet 120 based on the first air panel 200, closing the first air outlet section 117 based on the first sub-air panel 310, and closing the second air outlet section 118 based on the second sub-air panel 320 (e.g. Figure 17 As shown in the diagram, when the second sub-air vane 320 opens the second air outlet section 118, the first sub-air vane 310 is simultaneously controlled to open the first air outlet section 117. This allows the first sub-air vane 310 to avoid the movement trajectory of the second sub-air vane 320, preventing the first sub-air vane 310 from affecting the normal opening of the second sub-air vane 320. At this time, the second air outlet section 118 is in the open state, the lower air outlet 120 is in the closed state, and the first air outlet section 117 may be in the open state or may be in the closed state by the second sub-air vane 320. After the second sub-air vane 320 opens the second air outlet section 118, the first air vane 200 is then controlled to open the lower air outlet 120, so that the lower air outlet 120 is also in the open state (of course, it is also possible not to control the first air vane 200 to open the lower air outlet 120).
