[0033] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0034] like Figures 1 to 5 As shown, the air conditioner indoor unit 100 of the embodiment of the present disclosure includes a housing 1 and an air guide plate 2. The housing 1 is provided with an air inlet 11 and an air outlet 12. The air outlet 12 is provided above the air inlet 11. The air guide plate 2 is movably provided at the air outlet 12 to open or close the air outlet 12. During the movement of the air guide plate 2, the following conditions are satisfied:

[0035] L*cosc<D;

[0036] Among them, L is the dimension of the air guide plate 2 located on the upper side of the shell 1, C is the angle between the air guide plate 2 and the vertical plane, and when the air outlet direction at the air outlet 12 is facing forward and downward, C is a negative angle, and when the air outlet direction at the air outlet 12 is facing forward and upward, C is a positive angle, and D is the design distance between the upper end of the shell 1 and the roof 10.

[0037] like Figure 3 As shown, L*cos c is X, where X is the vertical dimension of the portion of the air deflector 2 located on the upper side of the housing 1, and D is the distance between the upper end of the housing 1 and the roof 10 after the air conditioner indoor unit 100 is installed. In the air conditioner indoor unit 100 of the present embodiment, by ensuring that L*cos c < D, the air deflector 2 does not interfere with the roof 10 during movement, ensuring normal operation of the air conditioner indoor unit 100 after installation.

[0038] In some embodiments, as Figure 5 As shown, the air conditioner indoor unit 100 further includes a rocker arm 3, which is rotatably connected to the housing 1 via a first rotating shaft 31 and is rotatably connected to the air deflector 2 via a second rotating shaft 32. Rotation of the rocker arm 3 drives the air deflector 2. Wherein, L*cos c=A+RB. Figure 2 The dotted line J in FIG. 3 is the motion trajectory of the second rotating shaft 32, and the rotation angle range of the second rotating shaft 32 is G.

[0039] A is the distance from the upper end of the deflector 2 to the horizontal plane passing through the center of the second rotating shaft 32 when the deflector 2 is parallel to the vertical plane; R is the distance between the center of the first rotating shaft 31 and the center of the second rotating shaft 32; and B is the distance from the upper end of the deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 when the second rotating shaft 32 is at the uppermost end.

[0040] It can be understood that, as shown in Figure 5 the second rotating shaft 32 is at the uppermost end, and the deflector 2 is at the largest size on the upper side of the shell 1 when the deflector 2 is parallel to the vertical plane, and the deflector 2 is most likely to interfere with the roof 10. In addition, when the first rotating shaft 31 is directly below the second rotating shaft 32, that is, the line connecting the center of the first rotating shaft 31 and the center of the second rotating shaft 32 is parallel to the vertical plane, the distance from the upper end of the deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 is the sum of A and R. When the first rotating shaft 31 is below the second rotating shaft 32, and the line connecting the center of the first rotating shaft 31 and the center of the second rotating shaft 32 intersects the vertical plane, the distance from the upper end of the deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 is B. Therefore, the sum of A and R is greater than B.

[0041] L*cos c = A + R - B, which is convenient to obtain L*cos c, that is, Figure 2 the value of X in the formula, thereby facilitating the design of the air conditioner indoor unit 100.

[0042] It should be noted that, when specifically designing the air conditioner indoor unit 100, the parameters R and B need to be designed, and L, c and A change with the movement of the deflector 2.

[0043] As shown in Figure 1 , Figure 2 and Figure 4 , the air conditioner indoor unit 100 further comprises a fan 4 and a heat exchanger 5, and the fan 4 and the heat exchanger 5 are arranged in the interior of the shell 1. When the air conditioner indoor unit 100 is working, the airflow enters the interior of the shell 1 through the air inlet 11 under the drive of the fan 4, flows through the heat exchanger 5 and exchanges heat with the heat exchanger 5, and then flows out through the air outlet 12.

[0044] In some embodiments, the shell 1 comprises a front panel 13, and the air outlet 12 is arranged on the upper side of the front panel 13, and the front panel 13 is arranged to gradually tilt backward in the direction from top to bottom.

[0045] By arranging the front panel 13 to gradually tilt backward in the direction from top to bottom, when the air conditioner indoor unit 100 is in the heating mode, the airflow flowing out of the air outlet 12 can enter the interior of the shell 1 from the lower side of the air outlet 12 through the air inlet 11, so that the temperature of the airflow entering the air inlet 11 is relatively high, and high-temperature sterilization of the heat exchanger 5 can also be achieved.

[0046] Optionally, asFigure 1 As shown, when the air deflector 2 is in the closed state, the front surface of the air deflector 2 is in the same plane as the front surface of the front panel 13.

[0047] When the air deflector 2 is in the closed state, the front surface of the air deflector 2 is in the same plane as the front surface of the front panel 13, so that the air deflector 2 can effectively close the air outlet 12 to avoid the air outlet 12 having a gap.

[0048] Optionally, the angle between the front panel 13 and the vertical plane is 0°-30°.

[0049] For example, as shown in Figure 1 The angle between the front panel 13 and the vertical plane is a, and a is 0°-30°.

[0050] It can be understood that the larger the angle between the front panel 13 and the vertical plane, the more hot air flows into through the air inlet 11, and the better the high-temperature sterilization effect of the heat exchanger 5, but the less the hot air in the room, which is not conducive to improving the heating effect of the air conditioner indoor unit 100; and the smaller the angle between the front panel 13 and the vertical plane, the less hot air flows into through the air inlet 11, and the more hot air in the room, which is conducive to improving the heating effect of the air conditioner indoor unit 100, but the worse the high-temperature sterilization effect of the heat exchanger 5.

[0051] By setting the angle between the front panel 13 and the vertical plane to 0°-30°, the high-temperature sterilization effect of the heat exchanger 5 can be ensured without affecting the indoor heating effect.

[0052] In some embodiments, D is greater than 0.

[0053] D being greater than 0 makes the distance between the upper end of the shell 1 and the ceiling 10 greater than 0 after the air conditioner indoor unit 100 is installed, i.e., there is a gap between the upper end of the shell 1 and the ceiling 10, so that the distance between the upper end of the shell 1 and the ceiling 10 is larger, which more effectively avoids interference between the air deflector 2 and the ceiling 10 during movement of the air deflector 2.

[0054] Optionally, D is greater than or equal to 30 mm.

[0055] D being greater than or equal to 30 mm makes the distance between the upper end of the shell 1 and the ceiling 10 greater than or equal to 30 mm after the air conditioner indoor unit 100 is installed, so that the gap between the upper end of the shell 1 and the ceiling 10 is larger, thereby making the distance between the upper end of the shell 1 and the ceiling 10 larger, which more effectively avoids interference between the air deflector 2 and the ceiling 10 during movement of the air deflector 2. In addition, during installation of the air conditioner indoor unit 100, there can also be a small movement in the up-down direction to facilitate installation and fixation of the air conditioner indoor unit 100.

[0056] In some embodiments, as shown in Figure 2As shown, when the air conditioner indoor unit 100 is in heating mode, C is a negative angle or zero, and the air outlet 12 is directed forward and downward. When the air conditioner indoor unit 100 is in cooling mode, C is a positive angle, and the air outlet 12 is directed forward and upward.

[0057] When the air conditioner 100 is in heating mode, the air outlet 12 is directed forward and downward, which can increase the landing speed of the air flowing out of the air outlet 12 and improve the heating effect of the air conditioner 100. When the air conditioner 100 is in cooling mode, the air outlet 12 is directed forward and upward, which can reduce the vortex generated by the air flowing out of the air outlet 12 and avoid condensation problems in the air conditioner 100.

[0058] Optionally, A is 50 mm to 80 mm. For example, A is 63.27 mm.

[0059] like Figure 4 As shown, when the air guide plate 2 is parallel to the vertical plane, the distance A from the upper end of the air guide plate 2 to the horizontal plane passing through the center of the second rotating shaft 32 is the largest.

[0060] By setting A to 50 mm to 80 mm, interference between the air guide plate 2 and the roof 10 during movement can be effectively avoided.

[0061] Optionally, R is 85 mm to 95 mm. For example, R is 90.1 mm.

[0062] By setting R to 85 mm to 95 mm, interference between the air guide plate 2 and the roof 10 during movement can be effectively avoided.

[0063] Optionally, B is 140 mm to 160 mm. For example, B is 148.09 mm.

[0064] When the second rotating shaft 32 moves to the uppermost end, the distance B between the upper end of the air guide plate 2 and the horizontal plane passing through the center of the first rotating shaft 31 is the largest.

[0065] By setting B to 140 mm to 160 mm, interference between the wind deflector 2 and the roof 10 during movement can be effectively avoided.

[0066] Optionally, the width of the air guide plate 2 is 88 mm to 124 mm.

[0067] For example, Figure 2 As shown, the width of the air guide plate 2 is K, and K is 88 mm to 124 mm.

[0068] By setting the width of the air guide plate 2 to 88 mm to 124 mm, it can be ensured that the air guide plate 2 effectively closes the air outlet 12, and the air outlet effect of the air conditioner indoor unit 100 in different working modes is better.
