[0038] 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.

[0039] like Figures 1 to 8 As shown, the air conditioner indoor unit 100 of the disclosed embodiment includes a housing 1, an air deflector 2, and a rocker arm 3. The housing 1 is provided with an air inlet 11 and an air outlet 12, with the air outlet 12 being located above the air inlet 11. The air deflector 2 is movably disposed at the air outlet 12 to open or close the air outlet 12. A first rotating shaft 31 and a second rotating shaft 32 are respectively provided at each end of the rocker arm 3. The first rotating shaft 31 is rotatably connected to the interior of the housing 1, and the second rotating shaft 32 is rotatably connected to the air deflector 2. The rocker arm 3 is used to drive the air deflector 2 to move.

[0040] The air conditioner indoor unit 100 of the embodiment of the present disclosure, by rotatingly connecting the first rotating shaft 31 of the rocker arm 3 with the inside of the shell 1, so that a part of the rocker arm 3 can move to the outside of the air outlet 12; by rotatingly connecting the second rotating shaft 32 of the rocker arm 3 with the air deflector 2, so that the air deflector 2 can move to the outside of the air outlet 12, thereby the air deflector 2 can improve the air sweeping angle, and improve the air outlet effect of the air conditioner indoor unit 100.

[0041] As shown in Figures 1 to 8 , 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 inside of the shell 1. When the air conditioner indoor unit 100 works, the airflow enters the inside of the shell 1 through the air inlet 11 under the driving of the fan 4, and flows through the heat exchanger 5 and exchanges heat with the heat exchanger 5, and then flows out through the air outlet 12.

[0042] As shown in Figure 1 and Figure 2 , the shell 1 comprises a front panel 13, and the air outlet 12 is arranged on the upper side of the front panel 13. The front panel 13 is parallel to the vertical direction, and when the air deflector 2 closes the air outlet 12, the air deflector 2 is parallel to the vertical direction.

[0043] For example, the front panel 13 is parallel to the up-down direction, and when the air deflector 2 closes the air outlet 12, the air deflector 2 is parallel to the up-down direction.

[0044] By arranging the front panel 13 to be parallel to the vertical direction, the processing and manufacturing of the shell 1 are facilitated, which is conducive to reducing the cost of the air conditioner indoor unit 100. When the air deflector 2 closes the air outlet 12, the air deflector 2 is parallel to the vertical direction, which can improve the air sweeping angle of the air deflector 2 and improve the air outlet effect of the air conditioner indoor unit 100.

[0045] Optionally, as shown in Figure 1 , when the air deflector 2 closes the air outlet 12, the distance between the center of the first rotating shaft 31 and the front side of the front panel 13 is L1, and L1 is 15mm-30mm, and the distance between the center of the first rotating shaft 31 and the upper surface of the shell 1 is L2, and L2 is 120mm-150mm.

[0046] For example, as shown in Figure 1 , when the air deflector 2 closes the air outlet 12, in the front-rear direction, the distance between the center of the first rotating shaft 31 and the front side of the front panel 13 is L1; in the up-down direction, the distance between the center of the first rotating shaft 31 and the upper surface of the shell 1 is L2.

[0047] By designing the position of the center of the first rotating shaft 31 when the air deflector 2 closes the air outlet 12, the air sweeping angle of the air deflector 2 can be improved, and the air outlet effect of the air conditioner indoor unit 100 can be improved.

[0048] Optionally, as shown inFigure 1 As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the second rotating shaft 32 and the front side surface of the air guide plate 2 is L3, L3 is 15mm~30mm, and the distance between the center of the second rotating shaft 32 and the upper surface of the shell 1 is L4, L4 is 50mm~70mm.

[0049] For example, Figure 1 As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the second rotating shaft 32 and the front side surface of the front panel 13 in the front-to-back direction is L3; in the up-down direction, the distance between the center of the second rotating shaft 32 and the upper surface of the shell 1 is L4.

[0050] By designing the center of the second rotating shaft 32 to the above position when the air guide plate 2 closes the air outlet 12, it is beneficial to increase the wind sweeping angle of the air guide plate 2 and improve the air outlet effect of the air conditioner indoor unit 100.

[0051] Alternatively, as Figure 3 As shown, the air deflector 2 has a first extreme position of downward movement. At the first extreme position, the angle A between the front side surface of the air deflector 2 and the front side surface of the front panel 13 is 100° to 130°.

[0052] It can be understood that the air guide plate 2 is in the first extreme position when the air guide plate 2 is in the maximum downward rotation angle state when the air conditioner indoor unit 100 is in the cooling mode.

[0053] By setting the angle A between the front side surface of the air guide plate 2 and the front side surface of the front panel 13 to 100°~130° when the air guide plate 2 is in the first extreme position, the wind sweeping angle of the air guide plate 2 can be increased when the air-conditioning indoor unit 100 is in cooling mode, thereby improving the cooling effect of the air-conditioning indoor unit 100.

[0054] Alternatively, as Figure 3 As shown, in the first extreme position, the distance between the front end of the second rotating shaft 32 and the rear end of the rocker arm 3 is L11, the distance between the front end of the second rotating shaft 32 and the front side of the front panel 13 is L12, and the ratio of L12 to L11 is 0.25~0.67.

[0055] It can be understood that the air guide plate 2 is in the first extreme position when the air guide plate 2 is in the maximum downward rotation angle state when the air conditioner indoor unit 100 is in the cooling mode.

[0056] By setting the ratio of L12 to L11 to 0.25-0.67 when the air guide plate 2 is in the first extreme position, the wind sweeping angle of the air guide plate 2 can be increased when the air conditioning indoor unit 100 is in cooling mode, thereby improving the cooling effect of the air conditioning indoor unit 100.

[0057] Optionally, L11 is 90 mm to 120 mm.

[0058] By setting L11 to 90mm-120mm when the deflector 2 is in the first limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the cooling mode can be improved, and the cooling effect of the air conditioner indoor unit 100 can be improved.

[0059] Optionally, L12 is 30mm-60mm.

[0060] By setting L12 to 30mm-60mm when the deflector 2 is in the first limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the cooling mode can be improved, and the cooling effect of the air conditioner indoor unit 100 can be improved.

[0061] Optionally, as shown in Figure 4 the deflector 2 has a second limit position of upward movement, and an included angle B between the front side of the deflector 2 and the front side of the front panel 13 in the second limit position is 30°-60°.

[0062] It can be understood that the second limit position of the deflector 2 is a maximum angle state of upward rotation of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode.

[0063] By setting the included angle B between the front side of the deflector 2 and the front side of the front panel 13 to 30°-60° when the deflector 2 is in the second limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be improved, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0064] Optionally, as shown in Figure 4 the deflector 2 has a second limit position of upward movement, and a spacing between the front end of the second rotating shaft 32 and the rear end of the rocker arm 3 in the second limit position is L13, a spacing between the front end of the second rotating shaft 32 and the front side of the front panel 13 in the second limit position is L14, and a ratio of L14 to L13 is 0.18-0.63.

[0065] It can be understood that the second limit position of the deflector 2 is a maximum angle state of upward rotation of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode.

[0066] By setting the ratio of L14 to L13 to 0.18-0.63 when the deflector 2 is in the second limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be improved, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0067] Optionally, L13 is 80mm-110mm.

[0068] By setting L13 to 80mm-110mm when the deflector 2 is in the second limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be improved, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0069] Optionally, L14 is 20mm-50mm.

[0070] By setting L14 to 20mm-50mm when the deflector 2 is in the second limit position, the air sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be improved, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0071] Optionally, as shown in Figure 2 the housing 1 is provided with an air outlet air duct 4, the air outlet air duct 4 includes an arc segment 41 and a straight segment 42, and the straight segment 42 is arranged on the front side of the arc segment 41. The dimension L10 of the straight segment 42 in the front-rear direction is 90mm-110mm.

[0072] Among them, the arc segment 41 can change the flow direction of the airflow under the condition of reducing the airflow resistance, and the straight segment 42 can better guide the flow direction of the airflow, so that the airflow flows out through the air outlet 12 along the preset direction.

[0073] For example, as shown in Figure 2 the straight segment 42 is gradually arranged upward along the direction from front to back. The dimension L10 of the straight segment 42 in the front-rear direction is 90mm-110mm.

[0074] The dimension of the straight segment 42 in the front-rear direction is set to 90mm-110mm. In the case that the length of the straight segment 42 is small, the flow direction of the airflow can be better guided, so that the airflow flows out through the air outlet 12 along the preset direction, and the air outlet effect of the air conditioner indoor unit 100 is improved.

[0075] In some embodiments, as shown in Figures 5 to 8 the deflector 2 is gradually arranged forwardly along the direction from bottom to top when the deflector 2 closes the air outlet 12.

[0076] For example, the front panel 13 is parallel to the up-down direction, and the deflector 2 is gradually arranged forwardly along the direction from bottom to top when the deflector 2 closes the air outlet 12.

[0077] When the deflector 2 closes the air outlet 12, the deflector 2 is gradually arranged forwardly along the direction from bottom to top, which can improve the air sweeping angle of the deflector 2 and improve the air outlet effect of the air conditioner indoor unit 100.

[0078] Optionally, as shown in Figure 5As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the first rotating shaft 31 and the front side surface of the front panel 13 is L5, L5 is 10mm~30mm, and the distance between the center of the first rotating shaft 31 and the upper surface of the shell 1 is L6, L6 is 110mm~150mm.

[0079] For example, Figure 5 As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the first rotating shaft 31 and the front side surface of the front panel 13 in the front-to-back direction is L5; in the up-down direction, the distance between the center of the first rotating shaft 31 and the upper surface of the shell 1 is L6.

[0080] By designing the center of the first rotating shaft 31 at the above position when the air guide plate 2 closes the air outlet 12, it is beneficial to increase the wind sweeping angle of the air guide plate 2 and improve the air outlet effect of the air conditioner indoor unit 100.

[0081] Alternatively, as Figure 5 As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the second rotating shaft 32 and the front side surface of the air guide plate 2 is L7, L7 is 10mm~30mm, and the distance between the center of the second rotating shaft 32 and the upper surface of the shell 1 is L8, L8 is 45mm~70mm.

[0082] For example, Figure 5 As shown, when the air guide plate 2 closes the air outlet 12, the distance between the center of the second rotating shaft 32 and the front side surface of the front panel 13 in the front-to-back direction is L7; in the up-down direction, the distance between the center of the second rotating shaft 32 and the upper surface of the shell 1 is L8.

[0083] By designing the center of the second rotating shaft 32 to the above position when the air guide plate 2 closes the air outlet 12, it is beneficial to increase the wind sweeping angle of the air guide plate 2 and improve the air outlet effect of the air conditioner indoor unit 100.

[0084] Optionally, when the air guide plate 2 closes the air outlet 12 , an angle E between the front side surface of the air guide plate 2 and the upper surface of the shell 1 is 65° to 95°.

[0085] When the air outlet 12 is closed by the air guide plate 2, the angle E between the front side surface of the air guide plate 2 and the upper surface of the shell 1 is set to 65°~95°, which is beneficial to increasing the wind sweeping angle of the air guide plate 2 and improving the air outlet effect of the air conditioner indoor unit 100.

[0086] Alternatively, as Figure 7 As shown, the air deflector 2 has a first extreme position of downward movement. At the first extreme position, the angle C between the front side surface of the air deflector 2 and the front side surface of the front panel 13 is 100° to 130°.

[0087] It can be understood that the air guide plate 2 is in the first extreme position when the air guide plate 2 is in the maximum downward rotation angle state when the air conditioner indoor unit 100 is in the cooling mode.

[0088] By setting the angle C between the front side of the air guide plate 2 and the front side of the front panel 13 to 100°~130° when the air guide plate 2 is in the first extreme position, the wind sweeping angle of the air guide plate 2 when the air-conditioning indoor unit 100 is in cooling mode can be increased, thereby improving the cooling effect of the air-conditioning indoor unit 100.

[0089] Alternatively, as Figure 7 As shown, in the first extreme position, the distance between the front end of the second rotating shaft 32 and the rear end of the rocker arm 3 is L15, and the distance between the front end of the second rotating shaft 32 and the front side of the front panel 13 is L16, and the ratio of L16 to L15 is 0.25~0.67.

[0090] It can be understood that the air guide plate 2 is in the first extreme position when the air guide plate 2 is in the maximum downward rotation angle state when the air conditioner indoor unit 100 is in the cooling mode.

[0091] By setting the ratio of L16 to L15 to 0.25-0.67 when the air guide plate 2 is in the first extreme position, the wind sweeping angle of the air guide plate 2 can be increased when the air conditioner indoor unit 100 is in cooling mode, thereby improving the cooling effect of the air conditioner indoor unit 100.

[0092] Optionally, L15 is 90 mm to 120 mm.

[0093] By setting L15 to 90 mm to 120 mm when the air guide plate 2 is in the first limit position, the wind sweeping angle of the air guide plate 2 can be increased when the air conditioner indoor unit 100 is in the cooling mode, thereby improving the cooling effect of the air conditioner indoor unit 100.

[0094] Optionally, L16 is 30 mm to 60 mm.

[0095] By setting L16 to 30 mm to 60 mm when the air guide plate 2 is in the first limit position, the wind sweeping angle of the air guide plate 2 can be increased when the air conditioner indoor unit 100 is in the cooling mode, thereby improving the cooling effect of the air conditioner indoor unit 100.

[0096] Alternatively, as Figure 8 As shown, the air deflector 2 has a second extreme position of upward movement. At the second extreme position, the angle D between the front side surface of the air deflector 2 and the front side surface of the front panel 13 is 25° to 55°.

[0097] It can be understood that the air guide plate 2 is in the second extreme position when the air guide plate 2 is in the maximum upward rotation angle state when the air conditioner indoor unit 100 is in the heating mode.

[0098] By setting the included angle D between the front side of the deflector 2 and the front side of the front panel 13 to be 25-55° when the deflector 2 is in the second limit position, the air-sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be increased, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0099] Alternatively, as shown in FIG. 6, in the second limit position, the distance between the front end of the second rotating shaft 32 and the rear end of the rocker arm 3 is L17, and the distance between the front end of the second rotating shaft 32 and the front side of the front panel 13 is L18. The ratio of L18 to L17 is 0.26-0.71. Figure 8

[0100] It can be understood that the second limit position of the deflector 2 is a maximum angle state of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode.

[0101] By setting the ratio of L18 to L17 to be 0.26-0.71 when the deflector 2 is in the second limit position, the air-sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be increased, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0102] Alternatively, L17 is 85-115 mm.

[0103] By setting L17 to be 85-115 mm when the deflector 2 is in the second limit position, the air-sweeping angle of the deflector 2 when the air conditioner indoor unit 100 is in the heating mode can be increased, and the heating effect of the air conditioner indoor unit 100 can be improved.

[0104] Alternatively, L18 is 30-60 mm.
