[0024] Therefore, the air conditioner indoor unit 100 according to the embodiments of the present application has the advantages of good refrigeration and heating effect, etc.

[0025] As shown in Figures 1-4 The air conditioner indoor unit 100 according to the embodiments of the present application includes a casing 1, a fan 2, and a heat exchanger 3. The casing 1 includes a first side plate 11, a second side plate 12, a front plate 13, a rear plate 14, a top plate 15, and a bottom plate 19.

[0026] The first side plate 11 and the second side plate 12 are arranged opposite to each other in the length direction of the casing 1, the front plate 13 and the rear plate 14 are arranged opposite to each other in the width direction of the casing 1, and the top plate 15 and the bottom plate 19 are arranged opposite to each other in the height direction of the casing 1.

Figure 1 as shown by arrow A in FIG. 1, the up-and-down direction as shown by arrow B in FIG. 1, and the front-and-rear direction as shown by arrow C in FIG. 1. Figure 1 as shown by arrow A in FIG. 1, the up-and-down direction as shown by arrow B in FIG. 1, and the front-and-rear direction as shown by arrow C in FIG. 1.

[0028] as shown by arrow A in FIG. 1, the up-and-down direction as shown by arrow B in FIG. 1, and the front-and-rear direction as shown by arrow C in FIG. 1. Figure 1 as shown by arrow A in FIG. 1, the up-and-down direction as shown by arrow B in FIG. 1, and the front-and-rear direction as shown by arrow C in FIG. 1. Figure 2 As shown in FIG. 1 and FIG. 2, the first side plate 11 and the second side plate 12 are both provided with air inlets 16. In this way, the air inlet area can be increased to increase the air inlet amount, and thus the air outlet amount can be increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects. Moreover, the air inlet direction can be increased, so that not only the return air can be more easily formed to speed up the circulation of the air (air flow) in the room, but also the circulation range of the air (air flow) in the room can be further increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects.

[0029] Optionally, the air inlets 16 of the first side plate 11 are arranged at the rear of the first side plate 11, and the air inlets 16 of the second side plate 12 are arranged at the rear of the second side plate 12. In this way, the air inlets 16 of the first side plate 11 are better matched with the first inlet 24 of the fan 2, and the air inlets 16 of the second side plate 12 are better matched with the second inlet 25 of the fan 2.

[0030] As shown in FIG. 1 and FIG. 2, the first side plate 11 and the second side plate 12 are both provided with air inlets 16. In this way, the air inlet area can be increased to increase the air inlet amount, and thus the air outlet amount can be increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects. Moreover, the air inlet direction can be increased, so that not only the return air can be more easily formed to speed up the circulation of the air (air flow) in the room, but also the circulation range of the air (air flow) in the room can be further increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects. Figure 1 Figure 2 As shown in FIG. 1 and FIG. 2, the first side plate 11 and the second side plate 12 are both provided with air inlets 16. In this way, the air inlet area can be increased to increase the air inlet amount, and thus the air outlet amount can be increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects. Moreover, the air inlet direction can be increased, so that not only the return air can be more easily formed to speed up the circulation of the air (air flow) in the room, but also the circulation range of the air (air flow) in the room can be further increased to make the cold air and the hot air blown out by the air conditioner indoor unit 100 cover the entire room more fully and more quickly, thereby further improving the refrigeration and heating effects.

[0031] Moreover, the cold air and the hot air blown out from the first air outlets 17 of the top plate 15 will not directly blow on the user, so that the air flow directly blowing on the user can be effectively reduced, so as to make the user feel more comfortable. Therefore, the air conditioner indoor unit 100 according to the embodiment of the present application also has the advantages of avoiding the cold air and the hot air directly blowing on the user and improving the comfort of the user.

[0032] In addition, by arranging the first air outlets 17 on the front plate 13 and the top plate 15, the cold air output by the fan 2 flows upwards, so as to avoid the cold air from quickly sinking, thereby making the cold air cover the entire room more evenly and improving the uniformity of the room temperature.

[0033] ​Optionally, the first air outlet 17 of the front panel 13 is arranged at the upper portion of the front panel 13, and the first air outlet 17 of the top panel 15 is arranged at the front portion of the top panel 15. In this way, the first air outlet 17 of the front panel 13 and the top panel 15 can be better matched with the outlet of the fan 2.

[0034] Optionally, the rear panel 14 is provided with a second air outlet 18. In this way, not only the air outlet area can be increased to increase the air outlet volume, but also the air outlet direction can be increased, so that the cold air and hot air blown by the air conditioner indoor unit 100 can more fully and quickly cover the entire room, and the refrigeration and heating effect can be improved. Especially when the length of the cabinet 1 is small, by arranging the second air outlet 18 on the rear panel 14, the air outlet volume can be further increased, so as to further improve the refrigeration and heating effect. Moreover, the cold air and hot air blown from the second air outlet 18 of the rear panel 14 will not directly blow on the user, so as to effectively reduce the air flow directly blowing on the user, so as to make the user feel more comfortable.

[0035] Optionally, the lower portion of the rear panel 14 is provided with a second air outlet 18. In this way, the second air outlet 18 of the rear panel 14 can be better matched with the outlet of the fan 2.

[0036] As shown in Figure 1 , Figure 3 and Figure 4 , the fan 2 includes a first outlet 21 and a second outlet 22, the first outlet 21 is matched with the first air outlet 17, and the second outlet 22 is matched with the second air outlet 18. In this way, the air output by the fan 2 can be better discharged through the first air outlet 17 and the second air outlet 18, so as to further increase the air outlet volume of the first air outlet 17 and the second air outlet 18, so that the cold air and hot air blown by the air conditioner indoor unit 100 can more fully and quickly cover the entire room, and the refrigeration and heating effect of the air conditioner indoor unit 100 can be further improved.

[0037] Optionally, the fan 2 is a centrifugal fan. In this way, the air output by the fan 2 can effectively overcome the resistance of the heat exchanger 3, and realize long-distance air distribution.

[0038] As shown in Figure 1 , the first outlet 21 is open forward and upward, and the second outlet 22 is open backward and downward. In this way, the first outlet 21 can be better matched with the first air outlet 17, and the second outlet 22 can be better matched with the second air outlet 18, so as to further increase the air outlet volume of the first air outlet 17 and the second air outlet 18, so that the cold air and hot air blown by the air conditioner indoor unit 100 can more fully and quickly cover the entire room, and the refrigeration and heating effect of the air conditioner indoor unit 100 can be further improved.

[0039] Optionally, the angle θ between the center line L1 of the first outlet 21 and the horizontal plane is greater than or equal to 30 degrees and less than or equal to 60 degrees. In this way, the resistance experienced by the air output from the first outlet 21 can be reduced, thereby improving the air supply effect of the first outlet 21 (fan 2).

[0040] Further optionally, the angle θ between the center line L1 of the first outlet 21 and the horizontal plane is greater than or equal to 40 degrees and less than or equal to 50 degrees. In this way, the resistance experienced by the air output from the first outlet 21 can be further reduced, thereby further improving the air supply effect of the first outlet 21 (fan 2).

[0041] Optionally, the angle α between the center line L2 of the second outlet 22 and the horizontal plane is greater than 0 degrees and less than or equal to 45 degrees. In this way, the resistance experienced by the air output from the second outlet 22 can be reduced, thereby improving the air supply effect of the second outlet 22 (fan 2).

[0042] Further optionally, the angle α between the center line L2 of the second outlet 22 and the horizontal plane is greater than or equal to 20 degrees and less than or equal to 30 degrees. In this way, the resistance experienced by the air output from the second outlet 22 can be further reduced, thereby further improving the air supply effect of the second outlet 22 (fan 2).

[0043] Optionally, the angle φ between the center line L1 of the first outlet 21 and the center line L2 of the second outlet 22 is greater than 0 degrees and less than or equal to 30 degrees. In this way, the resistance experienced by the air output from the first outlet 21 and the second outlet 22 can be reduced, thereby improving the air supply effect of the first outlet 21 and the second outlet 22 (fan 2).

[0044] Further optionally, the angle φ between the center line L1 of the first outlet 21 and the center line L2 of the second outlet 22 is greater than or equal to 10 degrees and less than or equal to 20 degrees. In this way, the resistance experienced by the air output from the first outlet 21 and the second outlet 22 can be further reduced, thereby further improving the air supply effect of the first outlet 21 and the second outlet 22 (fan 2).

[0045] As shown in Figure 1 , Figure 3 and Figure 4 , the casing 23 of the fan 2 includes a first outlet end 231 having the first outlet 21 and a second outlet end 232 having the second outlet 22. The angle β1 between the upper surface 2311 and the lower surface 2312 of the first outlet end 231 is greater than 21 degrees and less than or equal to 30 degrees, and the angle β2 between the upper surface 2321 and the lower surface 2322 of the second outlet end 232 is greater than 21 degrees and less than or equal to 30 degrees.

[0046] That is, the diffusion angle of the first outlet end 231 (the first outlet 21) of the fan 2 is greater than 21 degrees and less than or equal to 30 degrees, and the diffusion angle of the second outlet end 232 (the second outlet 22) of the fan 2 is greater than 21 degrees and less than or equal to 30 degrees. In this way, the resistance to the air output from the first outlet 21 and the second outlet 22 can be reduced, thereby improving the air supply effect of the first outlet 21 and the second outlet 22 (the fan 2).

[0047] Further optionally, the included angle β1 between the upper surface 2311 and the lower surface 2312 of the first outlet end 231 is greater than 26 degrees and less than or equal to 29 degrees, and the included angle β2 between the upper surface 2321 and the lower surface 2322 of the second outlet end 232 is greater than 26 degrees and less than or equal to 29 degrees. In this way, the resistance to the air output from the first outlet 21 and the second outlet 22 can be further reduced, thereby further improving the air supply effect of the first outlet 21 and the second outlet 22 (the fan 2).

[0048] As shown in Figure 1 and Figure 2 , the air inlet 16 is circular, and as shown in Figure 1 , Figure 3 and Figure 4 , the inlet of the fan 2 is circular. For example, the fan 2 includes a first inlet 24 and a second inlet 25, and both the first inlet 24 and the second inlet 25 are circular. The ratio of the radius of the air inlet 16 to the radius of the inlet of the fan 2 is greater than or equal to 1 and less than or equal to 1.2. In this way, the air inlet 16 can be better matched with the inlet of the fan 2, thereby further improving the air intake of the air conditioner indoor unit 100 and the fan 2, and further improving the air output of the air conditioner indoor unit 100 and the fan 2, so that the cold air and the hot air blown out by the air conditioner indoor unit 100 can more fully and more quickly cover the entire room, and the refrigeration and heating effect of the air conditioner indoor unit 100 is further improved.

[0049] Optionally, the ratio of the radius of the air inlet 16 of the first side plate 11 to the radius of the first inlet 24 of the fan 2 is greater than or equal to 1 and less than or equal to 1.2, and the ratio of the radius of the air inlet 16 of the second side plate 12 to the radius of the second inlet 25 of the fan 2 is greater than or equal to 1 and less than or equal to 1.2.

[0050] Optionally, a ratio of the radius of the air inlet 16 of the first side plate 11 to the radius of the first inlet 24 of the fan 2 is greater than or equal to 1.11 and less than or equal to 1.14, and a ratio of the radius of the air inlet 16 of the second side plate 12 to the radius of the second inlet 25 of the fan 2 is greater than or equal to 1.11 and less than or equal to 1.14. In this way, the air inlet 16 can be better matched with the inlet of the fan 2, thereby further improving the air inlet amount of the air conditioner indoor unit 100 and the fan 2, and further improving the air outlet amount of the air conditioner indoor unit 100 and the fan 2, so that the cold air and the hot air blown out by the air conditioner indoor unit 100 can more fully and more quickly cover the entire room, and the refrigeration and heating effect of the air conditioner indoor unit 100 is further improved.

[0051] As shown in Figure 1 The heat exchanger 3 is arranged in the cabinet 1, and the heat exchanger 3 includes a first side heat exchange part 31, a second side heat exchange part 32, and a front heat exchange part 33. The first side heat exchange part 31 is located between the first air inlet side of the fan 2 and the air inlet 16 of the first side plate 11, and the second side heat exchange part 32 is located between the second air inlet side of the fan 2 and the air inlet 16 of the second side plate 12. The front heat exchange part 33 is located between the outlet of the fan 2 and the first air outlet 17 in the width direction of the cabinet 1.

[0052] The air entering the cabinet 1 from the air inlet 16 of the first side plate 11 first flows through the first side heat exchange part 31 and exchanges heat with the first side heat exchange part 31. The air entering the cabinet 1 from the air inlet 16 of the second side plate 12 first flows through the second side heat exchange part 32 and exchanges heat with the second side heat exchange part 32. Then, the two parts of air are sucked into the fan 2 and output from the outlet of the fan 2. The air output from the outlet (for example, the first outlet 21) of the fan 2 flows through the front heat exchange part 33 and exchanges heat with the front heat exchange part 33, so as to achieve secondary heat exchange. In this way, the heat exchange efficiency of the heat exchanger 3 can be further improved, and the refrigeration and heating effect of the air conditioner indoor unit 100 is further improved.

[0053] Optionally, as shown in Figure 1 The first side heat exchange part 31 is located between the first inlet 24 of the fan 2 and the air inlet 16 of the first side plate 11 in the length direction of the cabinet 1, and the second side heat exchange part 32 is located between the second inlet 25 of the fan 2 and the air inlet 16 of the second side plate 12 in the length direction of the cabinet 1. In this way, the structure of the air conditioner indoor unit 100 can be more reasonable.

[0054] As shown in Figure 1As shown, the outlet of the fan 2 (e.g., the first outlet 21) opens forward and upward, and the front heat exchange section 33 is arranged at an angle. This allows the front heat exchange section 33 to be better aligned with the outlet of the fan 2, thereby increasing the heat exchange area of ​​the front heat exchange section 33. For example, the upper end of the front heat exchange section 33 is located behind the lower end of the front heat exchange section 33, which allows the front heat exchange section 33 to be better aligned with the outlet of the fan 2, thereby increasing the heat exchange area of ​​the front heat exchange section 33.

[0055] like Figure 1 As shown, each of the first side heat exchange section 31 and the second side heat exchange section 32 is arranged at an angle so that the first side heat exchange section 31 and the second side heat exchange section 32 can better cooperate with the front heat exchange section 33. The front end portion 311 of the first side heat exchange section 31 contacts the front heat exchange section 33, and the front end portion 321 of the second side heat exchange section 32 contacts the front heat exchange section 33.

[0056] This prevents air from entering the casing 1 from the air inlet 16 and air from the outlet of the fan 2 from flowing between the first heat exchange section 31 and the front heat exchange section 33, as well as between the second heat exchange section 32 and the front heat exchange section 33, so that the air can exchange heat with the heat exchanger 3 more fully and effectively, thereby further ensuring that the indoor unit 100 of the air conditioner has excellent cooling and heating effects.

[0057] Optionally, the front end portion 311 of the first heat exchange section 31 is connected to the front heat exchange section 33, and the front end portion 321 of the second heat exchange section 32 is connected to the front heat exchange section 33. This makes the structure of the heat exchanger 3 more stable and makes the heat exchanger 3 easier to assemble.

[0058] like Figure 1 As shown, the front heat exchange section 33 has a first end 331 and a second end 332 opposite to each other in the length direction of the housing 1. The front end 311 of the first side heat exchange section 31 is connected to the first end 331 of the front heat exchange section 33, and the front end 321 of the second side heat exchange section 32 is connected to the second end 332 of the front heat exchange section 33. This makes the structure of the heat exchanger 3 more stable, easier to assemble, and more rational.

[0059] Optionally, the thickness direction of the first heat exchange section 31 is consistent with the length direction of the housing 1, and the thickness direction of the second heat exchange section 32 is consistent with the length direction of the housing 1. This allows the first heat exchange section 31 and the second heat exchange section 32 to have a large heat exchange area.

[0060] like Figure 1As shown, the air conditioner indoor unit 100 further comprises a bearing support 4 and a bearing, the bearing support 4 is arranged on the rear plate 14, the top plate 15 or the bottom plate 19, and the bearing is arranged on the bearing support 4. The rotating shaft of the fan 2 is supported by the bearing. Therefore, the fan 2 can be installed more easily and more stably.

[0061] As shown, Figure 1 As shown, the motor 26 of the fan 2 is located between the first inlet 24 of the fan 2 and the first side heat exchange part 31 in the length direction of the casing 1. Alternatively, the motor 26 of the fan 2 is located between the second inlet 25 of the fan 2 and the second side heat exchange part 32 in the length direction of the casing 1.
