Alternatively, the rotation shaft of the first air deflector 310 is arranged near the upper edge of the first air outlet 210, and the rotation shaft of the second air deflector 320 is arranged near the upper edge of the second air outlet 220.

[0053] Further, in some embodiments of the utility model, as shown in Figure 3 The lower edge of the first air deflector 310 is arranged adjacent to the first air outlet 210, and the rotation shaft of the second air deflector 320 is arranged adjacent to the upper edge of the second air outlet 220.

[0054] In the embodiment, the first air deflector 310 is flipped downward when opening the first air outlet 210, and when the first air deflector 310 is in the state of opening the first air outlet 210, the first air deflector 310 is below the first air outlet 210, and the first air deflector 310 guides the airflow blown out by the first air outlet 210 to blow out to the front side or the front upper side.

Moreover, the rotation angle of the first air deflector 310 is not limited by the edge of the first air outlet 210, the angle between the first air deflector 310 and the first air outlet 210 is maximized, further avoiding the first air deflector 310 from shielding part of the first air outlet 210, thereby increasing the air outlet angle of the first air outlet 210, and further improving the air outlet effect of the air conditioner indoor unit 100 and the user's use experience.

[0057] In some embodiments of the utility model, the first air deflector 310 rotates inward or outward when rotating. The second air deflector 320 rotates inward or outward when rotating.

[0058] In the embodiment, the first air deflector 310 can rotate inwardly or outwardly when the first air outlet 210 is opened. When the first air deflector 310 rotates inwardly, the inner surface of the first air deflector 310 guides the flow of the air flow, and the rotation angle of the first air deflector 310 can be adjusted so that the first air deflector 310 guides the air in a specified direction. When the first air deflector 310 rotates outwardly, the edge of the first air outlet 210 does not block the rotation of the first air deflector 310, so that the rotation angle of the first air deflector 310 is larger, and the air supply angle of the first air outlet 210 is larger. The second air deflector 320 can rotate inwardly or outwardly when the second air outlet 220 is opened. When the second air deflector 320 rotates inwardly, the inner surface of the second air deflector 320 guides the flow of the air flow, and the rotation angle of the second air deflector 320 can be adjusted so that the second air deflector 320 guides the air in a specified direction. When the second air deflector 320 rotates outwardly, the rotation angle of the second air deflector 320 is larger, and the air supply angle of the second air outlet 220 is larger. The rotation mode of the first air deflector 310 and the second air deflector 320 can be determined according to the air outlet mode of the first air outlet 210 and the second air outlet 220, so as to adapt to different air outlet modes.

[0059] In some embodiments of the utility model, as shown in Figure 1 The shell 10 includes two side walls 160, a top wall 130, a bottom wall 140 and a front wall 110, and the two side walls 160, the top wall 130 and the front wall 110 define the first air outlet 210. The two side walls 160, the bottom wall 140 and the front wall 110 define the second air outlet 220. In the up-down direction, the width of the first air outlet 210 is equal to the width of the second air outlet 220, and the ratio of the width of the first air outlet 210 to the width of the front wall 110 is 1 / 3 to 1. In the left-right direction, the length of the first air outlet is equal to the length of the second air outlet, and the ratio of the length of the first air outlet to the length of the front wall is 4 / 5 to 1. For example, the ratio of the width of the first air outlet 210 to the width of the front wall 110 is 1 / 3, 1 / 2 or 1. The ratio of the length of the first air outlet to the length of the front wall is 4 / 5 or 1.

[0060] In the present embodiment, the area of the first air outlet 210 is equal to the area of the second air outlet 220. When the first air outlet 210 and the second air outlet 220 are opened at the same time, part of the airflow is blown out from the first air outlet 210, and another part of the airflow is blown out from the second air outlet 220. Since the air outlet areas of the first air outlet 210 and the second air outlet 220 are the same, the airflows blown out from the first air outlet 210 and the second air outlet 220 are the same, which improves the uniformity of airflow distribution and thus improves the uniformity of indoor temperature.

[0061] Preferably, the ratio of the width of the first air outlet 210 to the width of the front wall 110 is 1 / 2. In the left-right direction, the length of the first air outlet is equal to the length of the second air outlet, and the ratio of the length of the first air outlet to the length of the front wall is 1.

[0062] In some embodiments of the present application, as shown in Figures 2 to 5 The rear surface of the front wall 110 is the front surface of the air outlet cavity 150, and the rear surface of the front wall 110 is configured to guide the airflow from the axial flow fan.

[0063] In the present embodiment, the rear surface of the front wall 110 is the front surface of the air outlet cavity 150. When the air conditioner indoor unit 100 is running, the axial flow fan 40 blows air to the front side of the air outlet cavity 150, and the airflow flows in the air outlet cavity 150 and along the inner surface of the front wall 110 to the first air outlet 210 or the second air outlet 220. The inner surface of the front wall 110 serves to guide the airflow.

[0064] In some other embodiments of the present application, the front surface of the air outlet cavity 150 is convex forward.

[0065] In the embodiment, the front surface of the air outlet cavity 150 is convex forward, that is, the rear surface of the front wall 110 is convex forward. When the first air outlet 210 is closed, the air flow blows on the rear surface of the first air deflector 310 and the rear surface of the front wall 110, and the air flow blowing on the first air deflector 310 flows forward and downward along the rear surface of the first air deflector 310 and the front wall 110. When the second air outlet 220 is closed, the air flow blows on the rear surface of the second air deflector 320 and the rear surface of the front wall 110, and the air flow blowing on the second air deflector 320 flows forward and upward along the rear surface of the second air deflector 320 and the front wall 110. Since the rear surface of the front wall 110 is a convex inward structure convex forward, the air flow flows forward and downward or forward and upward after blowing on the rear surface of the first air deflector 310, the second air deflector 320 or the front wall 110, avoiding vortex of the air flow inside the first air deflector 310 or the second air deflector 320, reducing air flow resistance, thereby improving the air outlet amount of the air conditioner indoor unit 100, further improving the air outlet effect of the air conditioner indoor unit 100, and improving the user experience.

[0066] In some embodiments of the present application, as shown in Figure 6 The air conditioner indoor unit 100 further comprises a partition plate 60 and a flow guide grid 70. The partition plate 60 is arranged in the shell 10, and the partition plate 60, the top wall 130, the bottom wall 140 and the front wall 110 define an air outlet cavity 150. The partition plate 60 is provided with a through hole corresponding to the axial flow fan 40. The flow guide grid 70 is arranged in the through hole.

[0067] In the embodiment, the air outlet side of the axial flow fan 40 is provided with the flow guide grid 70. The air flow blown out of the axial flow fan 40 passes through the flow guide grid 70. The flow guide grid 70 improves the distribution of the air flow, reduces the disturbance of the air flow, and makes the blown air flow flow more smoothly, thereby reducing the loss of the air flow, improving the efficiency of the axial flow fan 40, further improving the air outlet effect of the air conditioner indoor unit 100, and further reducing the noise generated by the air flow by improving the distribution of the air flow, thereby reducing the noise of the air conditioner indoor unit 100 when running and improving the user experience.

[0068] In some embodiments of the present application, as shown in Figure 6 The axial flow fan 40 is provided with a plurality of axial flow fans 40 arranged transversely and side by side. The flow guide grid 70 is provided with a plurality of flow guide grids 70 corresponding to the axial flow fan 40.

[0069] In the embodiment, the air conditioner indoor unit 100 is internally provided with a plurality of axial flow fans 40, and each axial flow fan is provided with a flow guide grid 70 at the air outlet. The plurality of axial flow fans 40 send air to the front side, thereby improving the air outlet amount of the air conditioner indoor unit 100, and further improving the air outlet effect of the air conditioner indoor unit 100.

[0070] Further, the axial flow fan 40 is provided with two axial flow fans 40.

[0071] In some embodiments of the present application, as shown in Figures 2 to 5 The indoor air conditioner 100 further comprises an air guide ring 80, which is arranged on the side of the partition plate 60 close to the axial flow fan 40, and the axial flow fan 40 is arranged in the air guide ring 80.

[0072] In the present embodiment, the air guide ring 80 is arranged on the partition plate 60, and the axial flow fan 40 is arranged in the air guide ring 80. The arrangement of the air guide ring 80 reduces the clearance leakage of the axial flow fan 40 and reduces the loss of radial airflow, thereby improving the air supply efficiency and air supply performance of the axial flow fan 40, and further improving the air outlet effect of the indoor air conditioner 100.

[0073] In some embodiments of the present application, as shown in Figures 2 to 5 The indoor air conditioner 100 further comprises a heat exchanger 50, which is arranged on the front side of the partition plate 60.

[0074] In the present embodiment, the heat exchanger 50 is arranged on the front side of the partition plate 60, i.e. the axial flow fan 40 is located at the rear side of the heat exchanger 50, and the airflow first passes through the axial flow fan 40 and then enters the heat exchanger 50 for heat exchange. The cross-sectional area of the axial flow fan 40 is small, and when the air inlet 90 is arranged, the air inlet area of the air inlet 90 can be made as large as possible, thereby improving the air inlet amount of the indoor air conditioner 100, and further improving the air outlet amount of the indoor air conditioner 100.

[0075] In some embodiments of the present application, in the front-rear direction, the ratio of the thickness of the heat exchanger 50 to the thickness of the air outlet cavity 150 is 1 / 4 to 1 / 2. For example, the ratio of the thickness of the heat exchanger 50 to the thickness of the air outlet cavity 150 is 1 / 4, 1 / 3, or 1 / 2.

[0076] In the present embodiment, the heat exchanger 50 is located in the air outlet cavity 150, and the smaller the ratio of the thickness of the heat exchanger 50 to the thickness of the air outlet cavity 150, the more compact the structure of the indoor air conditioner 100, the smaller the temperature difference between the airflow on the air outlet side of the air outlet cavity 150 and the surface of the heat exchanger 50, and the better the air outlet effect of the indoor air conditioner 100. However, the rear surface of the heat exchanger 50 needs to have a certain interval with the rear surface of the air outlet cavity 150 to ensure the wind speed and air volume of the surface of the heat exchanger 50.

[0077] Preferably, in the front-rear direction, the ratio of the thickness of the heat exchanger 50 to the thickness of the air outlet cavity 150 is 1 / 3.

[0078] In some embodiments of the present application, the distance between the partition plate 60 and the heat exchanger 50 is 30mm to 40mm. For example, the distance between the partition plate 60 and the heat exchanger 50 is 30mm, 35mm or 40mm.

[0079] In the embodiment, the axial flow fan 40 is arranged in the air guide ring 80 at the rear side of the partition plate 60, and the distance between the partition plate 60 and the heat exchanger 50 is the distance between the partition plate 60 and the axial flow fan 40. With the increase of the distance between the partition plate 60 and the heat exchanger 50, the air volume of the air conditioner indoor unit 100 presents a trend of first increasing and then decreasing, but the change range is small. When the distance between the partition plate 60 and the heat exchanger 50 is 30 mm to 40 mm, the air volume is large. With the increase of the distance between the partition plate 60 and the heat exchanger 50, the air speed on the surface of the heat exchanger 50 gradually decreases, that is, the air outlet speed of the air conditioner indoor unit 100 gradually decreases. Therefore, considering the air volume and the air outlet speed of the air conditioner indoor unit 100 comprehensively, the distance between the partition plate 60 and the heat exchanger 50 is set to 30 mm to 40 mm.

[0080] Preferably, the distance between the partition plate 60 and the heat exchanger 50 is 35 mm.

[0081] In some embodiments of the utility model, the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50 is greater than or equal to 40 mm. For example, the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50 is 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm or 70 mm.

[0082] In the embodiment, with the increase of the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50, the air volume of air conditioner indoor unit 100 gradually increases, and the increase range gradually decreases after 40 mm. With the increase of the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50, the air outlet speed of air conditioner indoor unit 100 gradually decreases, and the decrease range gradually decreases after 40 mm. The smaller the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50, the more compact the structure of air conditioner indoor unit 100, and the production cost of air conditioner indoor unit 100 will also be reduced. Therefore, the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50 is greater than 40 mm.

[0083] Preferably, in some embodiments of the utility model, the distance between the front surface of air outlet cavity 150 and the front surface of heat exchanger 50 is 50 mm to 60 mm.

[0084] In the embodiment, when the distance between the front surface of air outlet cavity and the front surface of heat exchanger is 50 mm to 60 mm, the air volume and the air outlet speed of air conditioner indoor unit 100 tend to be balanced, and considering the air volume and the air outlet speed of air conditioner indoor unit comprehensively, the distance between the front surface of air outlet cavity and the front surface of heat exchanger is set to 50 mm to 60 mm.

[0085] In some embodiments of the utility model, as Figures 2 to 5As shown, the air conditioner indoor unit 100 further comprises an air inlet casing 120, which is located at the air inlet side of the axial flow fan 40, and the air inlet casing 120 comprises a rear casing 121 facing the rear side and a side casing 122, which is obliquely arranged and surrounds the rear casing 121, and the side casing 122 is provided with the air inlet 90.

[0086] In the embodiment, the air inlet casing 120 comprises the rear casing 121 and the side casing 122, and the side casing 122 is provided with the air inlet 90, i.e., the air flow is from the circumferential side air inlet of the air conditioner indoor unit 100.

[0087] In some embodiments of the present application, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit, a stand-type air conditioner indoor unit or other air conditioner indoor unit.

[0088] Preferably, in some embodiments of the present application, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit.
