[0024] The embodiments of the present utility model are described in detail below, examples of which are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and cannot be understood as a limitation of the present utility model.

[0025] The casing 1 of the air conditioner indoor unit 100 according to an embodiment of the present utility model is described below with reference to the drawings. As shown in Figures 1-6 the casing 1 of the air conditioner indoor unit 100 according to an embodiment of the present utility model includes a first side plate 11, a second side plate 12, a top plate 13 and a bottom plate 14.

[0026] The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the casing 1, the first side plate 11 is provided with a first air outlet (not shown in the drawing), and the second side plate 12 is provided with a second air outlet 121. The top plate 13 and the bottom plate 14 are oppositely arranged in the height direction of the casing 1, and the top plate 13 is provided with a third air outlet 131.

[0027] The casing 1 of the air conditioner indoor unit 100 according to an embodiment of the present utility model is provided with air outlets on the first side plate 11, the second side plate 12 and the top plate 13, so that side air outlet and top air outlet can be realized to avoid cold air and hot air directly blowing on the user, and the user feels more comfortable.

[0028] Moreover, by providing multiple air outlets (the first air outlet, the second air outlet 121 and the third air outlet 131), not only the air outlet area can be increased to increase the air outlet amount, but also the air outlet direction can be increased to make the cold air and hot air blown by the air conditioner indoor unit 100 more fully and more quickly cover the entire room, and the refrigeration and heating effect is improved. Especially when the length of the casing 1 is small, by providing the first air outlet and the second air outlet 121, the air outlet amount can be effectively improved to improve the refrigeration and heating effect.

[0029] Therefore, by using the casing 1 of the air conditioner indoor unit 100 according to an embodiment of the present utility model, the cold air and hot air can be avoided from directly blowing on the user, the comfort of the user is improved, and the refrigeration and heating effect is improved.

[0030] As shown in Figures 1-6 the air conditioner indoor unit 100 according to an embodiment of the present utility model includes a casing 1, a first fan 21, a first heat exchanger 3, a second fan 22 and a second heat exchanger 4.

[0031] The air outlet side of the first air fan 21 cooperates with each of the first air outlet and the third air outlet 131 of the casing 1, so that the cold air and the hot air output by the first air fan 21 is discharged through the first air outlet and the third air outlet 131. The first heat exchanger 3 is located between the air inlet 141 of the casing 1 and the air inlet side of the first air fan 21. The air outlet side of the second air fan 22 cooperates with each of the second air outlet 121 and the third air outlet 131 of the casing 1, so that the cold air and the hot air output by the second air fan 22 is discharged through the second air outlet 121 and the third air outlet 131. The second heat exchanger 4 is located between the air inlet 141 of the casing 1 and the air inlet side of the second air fan 22.

[0032] Therefore, the air conditioner indoor unit 100 according to the embodiment of the present application has the advantages of avoiding the cold air and the hot air from directly blowing on the user, improving the comfort of the user, good refrigeration and heating effect, and the like.

[0033] As shown in Figures 1-3 , the casing 1 comprises a first side plate 11, a second side plate 12, a top plate 13, a bottom plate 14, a front panel 16 and a back plate 17.

[0034] The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the casing 1, the first side plate 11 is provided with a first air outlet, and the second side plate 12 is provided with a second air outlet 121. The top plate 13 and the bottom plate 14 are oppositely arranged in the height direction of the casing 1, the top plate 13 is provided with a third air outlet 131, and the bottom plate 14 is provided with an air inlet 141. The front panel 16 and the back plate 17 are oppositely arranged in the width direction of the casing 1, and the front panel 16 can not be provided with an air outlet.

[0035] When the air conditioner indoor unit 100 is in the installed state, the length direction of the casing 1 can be consistent with the left-right direction, the height direction of the casing 1 can be consistent with the up-down direction, and the width direction of the casing 1 can be consistent with the front-rear direction. The left-right direction is shown by an arrow A in Figure 1 , the up-down direction is shown by an arrow B in Figure 1 , and the front-rear direction is shown by an arrow C in Figure 3 .

[0036] As shown in Figure 1 and Figure 2 , the first air outlet is arranged at the upper portion of the first side plate 11, and the second air outlet 121 is arranged at the upper portion of the second side plate 12. In this way, the first air outlet cooperates with the air outlet side of the first air fan 21, the second air outlet 121 cooperates with the air outlet side of the second air fan 22, and the first air fan 21 and the second air fan 22 are further facilitated to be installed in the casing 1.

[0037] As shown in Figure 2 and Figure 6As shown, the third air outlet 131 extends along the length direction of the casing 1, so as to further increase the area of the third air outlet 131. In this way, the air outlet area of the air conditioner indoor unit 100 can be further increased, so that the cold air and the hot air blown by the air conditioner indoor unit 100 can more fully and more quickly cover the entire room, so as to further improve the cooling and heating effect.

[0038] As shown in Figure 2 and Figure 3 As shown, the third air outlet 131 is multiple, and the multiple third air outlets 131 are arranged in the width direction of the casing 1. That is, the multiple third air outlets 131 are arranged in the front-rear direction. In this way, the air outlet area of the air conditioner indoor unit 100 can be further increased, so that the cold air and the hot air blown by the air conditioner indoor unit 100 can more fully and more quickly cover the entire room, so as to further improve the cooling and heating effect.

[0039] As shown in Figure 1 and Figure 2 As shown, the casing 1 further comprises a first air guide plate 151 and a second air guide plate 152. The first air guide plate 151 is rotatably arranged at the upper edge of the first air outlet of the first side plate 11 between a first closed position and a first air guide position. The second air guide plate 152 is rotatably arranged at the upper edge of the second air outlet 121 of the second side plate 12 between a second closed position and a second air guide position.

[0040] The rotation axis of the first air guide plate 151 extends along the width direction of the casing 1, and the rotation axis of the second air guide plate 152 extends along the width direction of the casing 1. The included angle between the first air guide plate 151 in the first air guide position and the vertically downward direction is greater than 0 degrees and less than or equal to 90 degrees. The included angle between the second air guide plate 152 in the second air guide position and the vertically downward direction is greater than 0 degrees and less than or equal to 90 degrees.

[0041] That is, the first air guide plate 151 is mounted to the first side plate 11, and when the first air guide plate 151 is in the first closed position, the upper end of the first air guide plate 151 is rotatably connected to the first side plate 11, and the upper end of the first air guide plate 151 is located at the upper edge of the first air outlet. When the first air guide plate 151 is in the first air guide position, the first air guide plate 151 extends obliquely downward or horizontally (is arranged) from the first side plate 11. In this way, when heating, the first air guide plate 151 can make the hot air flow downward to form "carpet wind", so that the hot air can more fully and more quickly cover the entire room, so as to further improve the heating effect.

[0042] The second air deflector 152 is installed on the second side plate 12. When the second air deflector 152 is in the second closed position, the upper end of the second air deflector 152 is rotatably connected to the second side plate 12, and the upper end of the second air deflector 152 is located at the upper edge of the second air outlet 121. When the second air deflector 152 is in the second air deflection position, the second air deflector 152 extends obliquely downward from the second side plate 12 or extends horizontally (is arranged). Thus, when heating, the second air deflector 152 can make the hot air flow downward to form "carpet wind", so that the hot air more fully and quickly covers the entire room, thereby further improving the heating effect.

[0043] As shown in Figure 2 and Figure 3 , the cabinet 1 further comprises a third air deflector 153 rotatably arranged at the rear edge of the third air outlet 131 of the top plate 13 between a third closed position and a third air deflection position. The rotation axis of the third air deflector 153 extends along the length direction of the cabinet 1. The third air deflector 153 in the third air deflection position forms an angle greater than 0 degrees and less than or equal to 90 degrees with the horizontal forward direction.

[0044] In other words, the third air deflector 153 is installed on the top plate 13. When the third air deflector 153 is in the third closed position, the rear end of the third air deflector 153 is rotatably connected to the top plate 13, and the rear end of the third air deflector 153 is located at the rear edge of the third air outlet 131. When the third air deflector 153 is in the third air deflection position, the third air deflector 153 extends obliquely forward and upward from the top plate 13 or extends vertically (is arranged). Thus, when cooling, the third air deflector 153 can make the cold air flow upward and forward, so that the cold air more fully and quickly covers the entire room, thereby further improving the cooling effect.

[0045] As shown in Figures 1-4 , the first fan 21 is an axial fan, and the first fan 21 is arranged obliquely so that the air outlet side of the first fan 21 faces each of the first air outlet and the third air outlet 131. The second fan 22 is an axial fan, and the second fan 22 is arranged obliquely so that the air outlet side of the second fan 22 faces each of the second air outlet 121 and the third air outlet 131.

[0046] The axial fan has the advantages of low pressure and high air volume. By making the first fan 21 and the second fan 22 axial fans, the air supply volume of the first fan 21 and the second fan 22 can be greatly improved, and the energy consumption of the first fan 21 and the second fan 22 (the air conditioner indoor unit 100) can be reduced, so that the cold air and the hot air blown by the air conditioner indoor unit 100 more fully and quickly covers the entire room, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100.

[0047] Moreover, by tilting the first fan 21 and the second fan 22, the first fan 21 and the second fan 22 can be better opposite to the air outlet, so as to reduce the airflow energy loss. Thus, the cold air and the hot air blown by the air conditioner indoor unit 100 can cover the whole room more fully and more quickly, and the cooling and heating effect of the air conditioner indoor unit 100 is further improved.

[0048] As shown in Figures 1-4 The air conditioner indoor unit 100 further comprises a first flow guide cover 5 and a second flow guide cover 6. The first flow guide cover 5 covers the first fan 21, and the second flow guide cover 6 covers the second fan 22. That is, the first flow guide cover 5 has a first flow guide cavity 51, and the first fan 21 is arranged in the first flow guide cavity 51. The second flow guide cover 6 has a second flow guide cavity 61, and the second fan 22 is arranged in the second flow guide cavity 61.

[0049] The first flow guide cover 5 is tilted, and the angle between the first fan 21 and the horizontal plane is equal to the angle between the first flow guide cover 5 and the horizontal plane. The second flow guide cover 6 is tilted, and the angle between the second fan 22 and the horizontal plane is equal to the angle between the second flow guide cover 6 and the horizontal plane. By arranging the first flow guide cover 5 and the second flow guide cover 6, the airflow can be gathered, so as to further improve the working efficiency and the air supply amount of the first fan 21 and the second fan 22. Thus, the cold air and the hot air blown by the air conditioner indoor unit 100 can cover the whole room more fully and more quickly, and the cooling and heating effect of the air conditioner indoor unit 100 is further improved.

[0050] Alternatively, the angle β1 between the first fan 21 and the horizontal plane is greater than or equal to 25 degrees and less than or equal to 45 degrees, and the angle β2 between the second fan 22 and the horizontal plane is greater than or equal to 25 degrees and less than or equal to 45 degrees. Correspondingly, the angle between the first flow guide cover 5 and the horizontal plane is greater than or equal to 25 degrees and less than or equal to 45 degrees, and the angle between the second flow guide cover 6 and the horizontal plane is greater than or equal to 25 degrees and less than or equal to 45 degrees. Thus, the air supply effect of the first fan 21 and the second fan 22 can be further improved, the efficiency of the first fan 21 and the second fan 22 can be further improved, the first fan 21 and the first flow guide cover 5 can not interfere with the arrangement of the first heat exchanger 3, the second fan 22 and the second flow guide cover 6 can not interfere with the arrangement of the second heat exchanger 4, and the difficulty of arranging the first heat exchanger 3 and the second heat exchanger 4 is reduced.

[0051] That is, when the angle between the first fan 21, the second fan 22, the first flow guide cover 5 and the second flow guide cover 6 and the horizontal plane is less than 25 degrees, the side air supply effect of the air conditioner indoor unit 100 is poor, which is not conducive to the discharge of the cold air and the hot air from the first air outlet and the second air outlet 121. Moreover, the first fan 21 and the first flow guide cover 5 can interfere with the arrangement of the first heat exchanger 3, and the second fan 22 and the second flow guide cover 6 can interfere with the arrangement of the second heat exchanger 4.

[0052] When the included angle between the first fan 21, the second fan 22, the first deflector 5 and the second deflector 6 and the horizontal plane is greater than 45 degrees, the top air outlet effect of the air conditioner indoor unit 100 is poor, which is not conducive to the cold air and the hot air being discharged from the third air outlet 131, and the gap between the first fan 21 and the second fan 22 is too large, which leads to the efficiency of the first fan 21 and the second fan 22 being reduced.

[0053] Further optionally, the included angle β1 between the first fan 21 and the horizontal plane is greater than or equal to 31 degrees and less than or equal to 39 degrees, and the included angle β2 between the second fan 22 and the horizontal plane is greater than or equal to 31 degrees and less than or equal to 39 degrees. Correspondingly, the included angle between the first deflector 5 and the horizontal plane is greater than or equal to 31 degrees and less than or equal to 39 degrees, and the included angle between the second deflector 6 and the horizontal plane is greater than or equal to 31 degrees and less than or equal to 39 degrees. In this way, the air outlet effect of the first fan 21 and the second fan 22 can be further improved, the efficiency of the first fan 21 and the second fan 22 can be further improved, the first fan 21 can be further prevented from interfering with the first heat exchanger 3, the second fan 22 can be further prevented from interfering with the second heat exchanger 4, and the difficulty of arranging the first heat exchanger 3 and the second heat exchanger 4 can be further reduced.

[0054] Optionally, the minimum distance between the first deflector 5 and the second deflector 6 in the length direction of the cabinet 1 is L1, the diameter of the first fan 21 is D1, and the diameter of the second fan 22 is D2. Wherein, L1 / D1 (the ratio of the minimum distance L1 to the diameter D1 of the first fan 21) is greater than or equal to 0.2 and less than or equal to 0.4, and L1 / D2 (the ratio of the minimum distance L1 to the diameter D2 of the second fan 22) is greater than or equal to 0.2 and less than or equal to 0.4. In this way, not only can the turbulent kinetic energy between the first deflector 5 and the second deflector 6 be reduced to reduce the aerodynamic noise of the air conditioner indoor unit 100, but also the size of the air conditioner indoor unit 100 in the length direction (the length direction of the cabinet 1) can be avoided to be too large, and the efficiency of the first fan 21 and the second fan 22 can be avoided to be reduced.

[0055] When L1 / D1 is less than 0.2 and L1 / D2 is less than 0.2, the turbulent kinetic energy between the first deflector 5 and the second deflector 6 will be large, which further leads to the aerodynamic noise being large. When L1 / D1 is greater than 0.4 and L1 / D2 is greater than 0.4, the size of the air conditioner indoor unit 100 in the length direction is too large, and the efficiency of the first fan 21 and the second fan 22 is also reduced.

[0056] Optionally, L1 / D1 is greater than or equal to 0.25 and less than or equal to 0.35, and L1 / D2 is greater than or equal to 0.25 and less than or equal to 0.35. In this way, not only can the turbulent kinetic energy between the first fairing 5 and the second fairing 6 be further reduced, so as to further reduce the aerodynamic noise of the air conditioner indoor unit 100, but also the size of the air conditioner indoor unit 100 in the length direction (the length direction of the cabinet 1) can be further avoided to be too large, and the efficiency of the first fan 21 and the second fan 22 can be further avoided to be reduced.

[0057] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the first heat exchanger 3 is arranged obliquely, and the oblique direction of the first heat exchanger 3 is consistent with the oblique direction of the first fan 21. For example, the left side of the first heat exchanger 3 is below the right side of the first heat exchanger 3, and the left side of the first fan 21 is below the right side of the first fan 21. The first heat exchanger 3 is opposite to the first fan 21. For example, the first heat exchanger 3 is opposite to the first fan 21 in the extension direction of the rotation axis of the first fan 21.

[0058] The second heat exchanger 4 is arranged obliquely, and the oblique direction of the second heat exchanger 4 is consistent with the oblique direction of the second fan 22. For example, the right side of the second heat exchanger 4 is below the left side of the second heat exchanger 4, and the right side of the second fan 22 is below the left side of the second fan 22. The second heat exchanger 4 is opposite to the second fan 22. For example, the second heat exchanger 4 is opposite to the second fan 22 in the extension direction of the rotation axis of the second fan 22.

[0059] In this way, the air sucked by the first fan 21 can first pass through the first heat exchanger 3, and the air sucked by the second fan 22 can first pass through the second heat exchanger 4, so that the air is fully heat-exchanged with the first heat exchanger 3 and the second heat exchanger 4 before being output by the first fan 21 and the second fan 22, so as to cool or heat the room.

[0060] As shown in Figure 1 , Figure 4 and Figure 5 , the upper end of the first heat exchanger 3 and the upper end of the second heat exchanger 4 are located between the lower end of the first heat exchanger 3 and the lower end of the second heat exchanger 4 in the length direction of the cabinet 1. In other words, the first heat exchanger 3 and the second heat exchanger 4 are arranged along the length direction of the cabinet 1. Correspondingly, the first fan 21 and the second fan 22 are arranged along the length direction of the cabinet 1, and the first fairing 5 and the second fairing 6 are arranged along the length direction of the cabinet 1. In this way, the structure of the air conditioner indoor unit 100 can be more reasonable.

[0061] The upper end of the first heat exchanger 3 and the upper end of the second heat exchanger 4 are in contact. Thus, air flow between the first heat exchanger 3 and the second heat exchanger 4 can be prevented, so that the first fan 21 and the second fan 22 can not suck in air which has not been exchanged heat with the first heat exchanger 3 and the second heat exchanger 4, so as to ensure that the air conditioner indoor unit 100 has excellent refrigeration and heating effects.

[0062] Optionally, the first heat exchanger 3 and the horizontal plane form an angle greater than or equal to 30 degrees and less than or equal to 45 degrees, and the second heat exchanger 4 and the horizontal plane form an angle greater than or equal to 30 degrees and less than or equal to 45 degrees. Thus, not only can the first heat exchanger 3 and the second heat exchanger 4 have a larger heat exchange area, but also the condensate water on the first heat exchanger 3 and the second heat exchanger 4 can not vertically drip, and the first heat exchanger 3 can not interfere with the arrangement of the first fan 21, and the second heat exchanger 4 can not interfere with the arrangement of the second fan 22.

[0063] As shown in Figure 1 , Figure 4 and Figure 5 , the first heat exchanger 3 includes a first main body part 31 and a first bending part 32. The first main body part 31 is arranged obliquely, and the oblique direction of the first main body part 31 is consistent with the oblique direction of the first fan 21. For example, the left side of the first main body part 31 is below the right side of the first main body part 31, and the left side of the first fan 21 is below the right side of the first fan 21. The first main body part 31 is opposite to the first fan 21. For example, the first main body part 31 is opposite to the first fan 21 in the extension direction of the rotation axis of the first fan 21.

[0064] The second heat exchanger 4 includes a second main body part 41 and a second bending part 42. The second main body part 41 is arranged obliquely, and the oblique direction of the second main body part 41 is consistent with the oblique direction of the second fan 22. For example, the right side of the second main body part 41 is below the left side of the second main body part 41, and the right side of the second fan 22 is below the left side of the second fan 22. The second main body part 41 is opposite to the second fan 22. For example, the second main body part 41 is opposite to the second fan 22 in the extension direction of the rotation axis of the second fan 22.

[0065] The first bending part 32 is arranged obliquely, and the lower end 321 of the first bending part 32 and the lower end 311 of the first main body part 31 are in contact. The second bending part 42 is arranged obliquely, and the lower end 421 of the second bending part 42 and the lower end 411 of the second main body part 41 are in contact. The first main body part 31 and the second main body part 41 are located between the first bending part 32 and the second bending part 42 in the length direction of the casing 1. Thus, the structure of the first heat exchanger 3 and the second heat exchanger 4 can be more reasonable.

[0066] As shown in Figure 1 , Figure 4 andFigure 5 As shown, the upper end 312 of the first main body 31 and the upper end 412 of the second main body 41 are in contact. Thus, air flow between the first main body 31 and the second main body 41 can be prevented, so that the first fan 21 and the second fan 22 can not suck in air which has not been heat-exchanged with the first heat exchanger 3 and the second heat exchanger 4, so as to ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects.

[0067] The upper end 312 of the first main body 31 and the upper end 412 of the second main body 41 are connected, the lower end 321 of the first bending part 32 and the lower end 311 of the first main body 31 are connected, and the lower end 421 of the second bending part 42 and the lower end 411 of the second main body 41 are connected. Thus, the structure of the first heat exchanger 3 and the second heat exchanger 4 can be more stable.

[0068] Optionally, the angle β3 between the first main body 31 and the horizontal plane is greater than or equal to 30 degrees and less than or equal to 45 degrees, and the angle β4 between the second main body 41 and the horizontal plane is greater than or equal to 30 degrees and less than or equal to 45 degrees. Thus, not only can the first main body 31 and the second main body 41 have a larger heat exchange area, but also the condensed water on the first main body 31 and the second main body 41 can not vertically drop, and the first main body 31 can not interfere with the arrangement of the first fan 21, and the second main body 41 can not interfere with the arrangement of the second fan 22.

[0069] When the angle between the first main body 31 and the horizontal plane is less than 30 degrees, and the angle between the second main body 41 and the horizontal plane is less than 30 degrees, not only the heat exchange area of the first main body 31 and the second main body 41 is too small, but also the condensed water on the first main body 31 and the second main body 41 can easily vertically drop. When the angle between the first main body 31 and the horizontal plane is greater than 45 degrees, and the angle between the second main body 41 and the horizontal plane is greater than 45 degrees, the first main body 31 can interfere with the arrangement (angle) of the first fan 21, and the second main body 41 can interfere with the arrangement (angle) of the second fan 22.

[0070] Further optionally, the angle β3 between the first main body 31 and the horizontal plane is greater than or equal to 36 degrees and less than or equal to 39 degrees, and the angle β4 between the second main body 41 and the horizontal plane is greater than or equal to 36 degrees and less than or equal to 39 degrees. Thus, not only can the first main body 31 and the second main body 41 have a larger heat exchange area, but also the condensed water on the first main body 31 and the second main body 41 can not vertically drop, and the first main body 31 can not interfere with the arrangement of the first fan 21, and the second main body 41 can not interfere with the arrangement of the second fan 22.

[0071] Optionally, the included angle β5 between the first body part 31 and the first bending part 32 is greater than or equal to 90 degrees and less than or equal to 120 degrees, and the included angle β6 between the second body part 41 and the second bending part 42 is greater than or equal to 90 degrees and less than or equal to 120 degrees. In this way, not only can the first body part 31 and the first bending part 32 be prevented from overlapping, and the second body part 41 and the second bending part 42 be prevented from overlapping, thereby avoiding reducing the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4, but also the first bending part 32 and the second bending part 42 have a larger effective heat exchange area.

[0072] When the included angle between the first body part 31 and the first bending part 32 is less than 90 degrees, and the included angle between the second body part 41 and the second bending part 42 is less than 90 degrees, the first body part 31 and the first bending part 32 will overlap, and the second body part 41 and the second bending part 42 will overlap, thereby reducing the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4. When the included angle between the first body part 31 and the first bending part 32 is greater than 120 degrees, and the included angle between the second body part 41 and the second bending part 42 is greater than 120 degrees, the effective heat exchange area of the first bending part 32 and the second bending part 42 will decrease.

[0073] Further optionally, the included angle β5 between the first body part 31 and the first bending part 32 is greater than or equal to 100 degrees and less than or equal to 110 degrees, and the included angle β6 between the second body part 41 and the second bending part 42 is greater than or equal to 100 degrees and less than or equal to 110 degrees. In this way, not only can the first body part 31 and the first bending part 32 be further prevented from overlapping, and the second body part 41 and the second bending part 42 be further prevented from overlapping, thereby avoiding reducing the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4, but also the first bending part 32 and the second bending part 42 have a larger effective heat exchange area.

[0074] Optionally, the minimum distance between the lower end 321 of the first bending part 32 and the lower end 421 of the second bending part 42 in the length direction of the casing 1 is L5, that is, the maximum distance between the lower end 311 of the first body part 31 and the lower end 411 of the second body part 41 in the length direction of the casing 1 is L5. The maximum distance between the lower end 511 of the first flow guide cavity 51 of the first flow guide cover 5 and the lower end 611 of the second flow guide cavity 61 of the second flow guide cover 6 in the length direction of the casing 1 is L6. Wherein, L5 is less than or equal to L6.

[0075] In this way, the first bending part 32 can be prevented from being far away from the first flow guide cavity 51 of the first flow guide cover 5, and the second bending part 42 can be prevented from being far away from the second flow guide cavity 61 of the second flow guide cover 6, thereby avoiding the amount of air flowing through the first bending part 32 and the second bending part 42 being too small, and effectively improving the heat exchange efficiency of the first bending part 32 and the second bending part 42.

[0076] Optionally, the maximum distance between the first fairing 5 and the second fairing 6 in the length direction of the shell 1 is L2, the maximum size of the air inlet 141 in the length direction of the shell 1 is L3, and the maximum distance between the first bending part 32 and the second bending part 42 in the length direction of the shell 1 is L4. Wherein, L3 is greater than L2, and L2 is greater than L4.

[0077] In the case of setting the first fairing 5 and the second fairing 6, the air flow (air after heat exchange with the first heat exchanger 3 and the second heat exchanger 4) is mainly pumped out by the first fairing 5 and the second fairing 6, so that the flow efficiency of the air flow in the gap between the first fairing 5 and the shell 1 and the gap between the second fairing 6 and the shell 1 is low. Even if the size of the first heat exchanger 3 and the second heat exchanger 4 in the length direction of the shell 1 is increased, so that the first heat exchanger 3 extends out of the first fairing 5 and the second heat exchanger 4 extends out of the second fairing 6, the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4 cannot be effectively increased.

[0078] By making L2 greater than L4, that is, L4 less than L2, the size of the first heat exchanger 3 and the second heat exchanger 4 can be reduced while ensuring the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4, so as to reduce the manufacturing cost of the first heat exchanger 3 and the second heat exchanger 4 (the air conditioner indoor unit 100).
