[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The following description, with reference to the accompanying drawings, describes an air conditioner indoor unit 100 according to an embodiment of the present invention. Figures 1-6 As shown, the indoor unit 100 of the air conditioner according to an embodiment of the present utility model includes a casing 1, a fan and a heat exchanger, each of which is disposed inside the casing 1.

[0027] The shell 1 includes a first side plate 11, a second side plate 12, a bottom plate 13 and a back plate. The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the shell 1, the first side plate 11 is provided with a first air outlet 111, and the second side plate 12 is provided with a second air outlet 121. At least one of the bottom plate 13 and the back plate is provided with an air inlet 14.

[0028] The air conditioner indoor unit 100 according to the embodiment of the present application can realize side air outlet by arranging the first air outlet 111 on the first side plate 11 and the second air outlet 121 on the second side plate 12, so as to avoid cold air and hot air directly blowing on the user, and make the user feel more comfortable.

[0029] In addition, the air conditioner indoor unit 100 according to the embodiment of the present application can effectively increase the air outlet area and the air outlet direction by arranging multiple air outlets (the first air outlet 111 and the second air outlet 121), so as to make the cold air and the hot air blown by the air conditioner indoor unit 100 more fully and more quickly cover the entire room, and improve the refrigeration and heating effect. Especially when the length of the shell 1 (the air conditioner indoor unit 100) is small, the air outlet amount can be effectively improved by arranging the first air outlet 111 and the second air outlet 121, so as to improve the refrigeration and heating effect.

[0030] Therefore, the air conditioner indoor unit 100 according to the embodiment of the present application has the advantages of avoiding cold air and hot air directly blowing on the user, improving the comfort of the user, good refrigeration and heating effect, and the like.

[0031] As shown in Figures 1-6 The air conditioner indoor unit 100 according to the embodiment of the present application includes a shell 1, a fan and a heat exchanger. Each of the fan and the heat exchanger is arranged in the shell 1.

[0032] The shell 1 includes a first side plate 11, a second side plate 12, a bottom plate 13, a top plate 17 and a back plate. The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the shell 1, and the bottom plate 13 and the top plate 17 are oppositely arranged in the height direction of the shell 1. The first side plate 11 is provided with a first air outlet 111, and the second side plate 12 is provided with a second air outlet 121. At least one of the bottom plate 13 and the back plate is provided with an air inlet 14.

[0033] When the air conditioner indoor unit 100 is in the installed state, the length direction of the shell 1 can be consistent with the left-right direction, the width direction of the shell 1 can be consistent with the front-rear direction, and the height direction of the shell 1 can be consistent with the up-down direction. The left-right direction is shown by an arrow A in Figure 3 , the front-rear direction is shown by an arrow B in Figure 2 , and the up-down direction is shown by an arrow C in Figure 3 .

[0034] AsFigures 1-3 As shown, the first air outlet 111 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 111 and the second air outlet 121 can be conveniently matched with the air outlet side of the fan, so as to facilitate the installation of the fan in the casing 1.

[0035] Optionally, the first air outlet 111 extends along the width direction of the casing 1, and the second air outlet 121 extends along the width direction of the casing 1. In this way, the air outlet area of the casing 1 and the air conditioner indoor unit 100 can be increased, so as to increase the air outlet volume of the casing 1 and the air conditioner indoor unit 100, so as to further improve the refrigeration and heating effect of the air conditioner indoor unit 100.

[0036] As shown, Figures 1-3 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 first air outlet 111 of the first side plate 11 between a first closed position and a first air guide position, and the rotation axis of the first air guide plate 151 extends along the width direction or the height direction of the casing 1. The second air guide plate 152 is rotatably arranged at the second air outlet 121 of the second side plate 12 between a second closed position and a second air guide position, and the rotation axis of the second air guide plate 152 extends along the width direction or the height direction of the casing 1.

[0037] When the air conditioner indoor unit 100 is in heating, the first air guide plate 151 located in the first air guide position extends obliquely downward or horizontally (is arranged), and the second air guide plate 152 located in the second air guide position extends obliquely downward or horizontally (is arranged). When the first air guide plate 151 (the second air guide plate 152) extends obliquely downward, the upper end of the first air guide plate 151 (the second air guide plate 152) is adjacent to the first side plate 11 (the second side plate 12) relative to the lower end of the first air guide plate 151 (the second air guide plate 152) in the length direction of the casing 1.

[0038] In other words, when the air conditioner indoor unit 100 is in heating, the first air guide plate 151 located in the first air guide position forms an angle with the vertical downward direction greater than 0 degrees and less than or equal to 90 degrees. The second air guide plate 152 located in the second air guide position forms an angle with the vertical downward direction greater than 0 degrees and less than or equal to 90 degrees. In this way, when heating, the first air guide plate 151 and the second air guide plate 152 can make the hot air flow downward to form "carpet wind", so as to make the hot air more fully and more quickly cover the entire room, so as to further improve the heating effect.

[0039] When the indoor unit 100 of the air conditioner is cooling, the first air guide plate 151 located at the first air guide position extends obliquely upward or horizontally (set), and the second air guide plate 152 located at the second air guide position extends obliquely upward or horizontally (set). When the first air guide plate 151 (second air guide plate 152) extends obliquely upward, the upper end of the first air guide plate 151 (second air guide plate 152) is farther away from the lower end of the first side plate 11 (second side plate 12) in the length direction of the housing 1.

[0040] In other words, when the indoor unit 100 of the air conditioner is cooling, the angle between the first air guide plate 151 located at the first air guide position and the vertical upward direction is greater than 0 degrees and less than or equal to 90 degrees. The angle between the second air guide plate 152 located at the second air guide position and the vertical upward direction is greater than 0 degrees and less than or equal to 90 degrees. This can further improve the user's comfort.

[0041] like Figures 1-3 As shown, the housing 1 further includes a first support member 161 and a first adjusting member 162, each of which is disposed on the first side plate 11. The first support member 161 is connected to the first air guide plate 151. At least a portion of the first adjusting member 162 is movably disposed along the length direction of the housing 1, and this at least portion of the first adjusting member 162 is connected to the first air guide plate 151.

[0042] In other words, the first adjusting member 162 can be movably arranged along the length direction of the housing 1 as a whole. In addition, a portion of the first adjusting member 162 is movably arranged along the length direction of the housing 1 so that this portion of the first adjusting member 162 is retractably arranged relative to the other portion of the first adjusting member 162 along the length direction of the housing 1.

[0043] like Figures 1-3 As shown, the housing 1 further includes a second support member 163 and a second adjusting member 164, each of which is disposed on the second side plate 12. The second support member 163 is connected to the second air guide plate 152. At least a portion of the second adjusting member 164 is movably disposed along the length direction of the housing 1, and this at least portion of the second adjusting member 164 is connected to the second air guide plate 152.

[0044] In other words, the second adjusting member 164 can be movably arranged along the length of the housing 1 as a whole. In addition, a portion of the second adjusting member 164 is movably arranged along the length of the housing 1 so that this portion of the second adjusting member 164 is retractably arranged relative to the other portion of the second adjusting member 164 along the length of the housing 1.

[0045] Therefore, by moving at least a portion of the first adjusting member 162 along the length of the housing 1, the tilt direction of the first air guide plate 151 and the angle between the first air guide plate 151 and the vertically downward and vertically upward directions can be changed. Furthermore, by moving at least a portion of the second adjusting member 164 along the length of the housing 1, the tilt direction of the second air guide plate 152 and the angle between the second air guide plate 152 and the vertically downward and vertically upward directions can be changed.

[0046] For example, when the indoor unit 100 of the air conditioner is not running, the first air guide plate 151 and the second air guide plate 152 can be set substantially vertically. When the indoor unit 100 of the air conditioner is heating, at least a portion of the first adjusting member 162 moves along the length direction of the housing 1 toward the adjacent first side plate 11 (second side plate 12) so that the first air guide plate 151 extends obliquely downward, and at least a portion of the second adjusting member 164 moves along the length direction of the housing 1 toward the adjacent second side plate 12 (first side plate 11) so that the second air guide plate 152 extends obliquely downward.

[0047] When the indoor unit 100 of the air conditioner is cooling, at least a portion of the first adjusting member 162 moves along the length direction of the casing 1 in a direction away from the first side plate 11 (second side plate 12) so that the first air guide plate 151 extends obliquely upward, and at least a portion of the second adjusting member 164 moves along the length direction of the casing 1 in a direction away from the second side plate 12 (first side plate 11) so that the second air guide plate 152 extends obliquely upward.

[0048] Optionally, at least a portion of the first adjusting member 162 is hinged to the first air guide plate 151, and the first supporting member 161 is hinged to the first air guide plate 151. This makes the structure of the housing 1 more rational. At least a portion of the second adjusting member 164 is hinged to the second air guide plate 152, and the second supporting member 163 is hinged to the second air guide plate 152. This makes the structure of the housing 1 more rational.

[0049] like Figures 1-3 As shown, the rotation axis of the first air guide plate 151 extends along the width direction of the housing 1. The housing 1 includes two first support members 161, which are spaced apart along the width direction of the housing 1. A first adjusting member 162 is located between the two first support members 161 in the width direction of the housing 1, and is positioned above the two first support members 161. This makes the structure of the housing 1 more reasonable.

[0050] Specifically, at least a portion of the first adjusting member 162 is hinged to the upper end of the first air guide plate 151, and each first support member 161 is hinged to the lower end of the first air guide plate 151. This makes the structure of the housing 1 more reasonable.

[0051] As shown in Figures 1-3 , the rotation axis of the second air deflector 152 extends along the width direction of the casing 1. The casing 1 comprises two second supporting members 163, which are arranged in the width direction of the casing 1. The second adjusting member 164 is located between the two second supporting members 163 in the width direction of the casing 1, and is located above the two second supporting members 163. In this way, the structure of the casing 1 can be more reasonable.

[0052] Specifically, the at least one part of the second adjusting member 164 is hinged to the upper end of the second air deflector 152, and each second supporting member 163 is hinged to the lower end of the second air deflector 152. In this way, the structure of the casing 1 can be more reasonable.

[0053] As shown in Figure 3 , Figure 4 and Figure 6 , the fan comprises a first fan 21a and a second fan 22a, the air outlet side of the first fan 21a is matched with the first air outlet 111 of the casing 1, and the air outlet side of the second fan 22a is matched with the second air outlet 121 of the casing 1. In this way, the air volume of the air conditioner indoor unit 100 can be further 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.

[0054] As shown in Figure 3 , Figure 4 and Figure 6 , the fan comprises a first axial fan 21 and a second axial fan 22, that is, the first fan 21a comprises the first axial fan 21, and the second fan 22a comprises the second axial fan 22. The first axial fan 21 is arranged obliquely, and the air outlet side of the first axial fan 21 is matched with the first air outlet 111 of the casing 1. The second axial fan 22 is arranged obliquely, and the air outlet side of the second axial fan 22 is matched with the second air outlet 121 of the casing 1.

[0055] The axial fan has the advantages of low pressure and high air volume. By arranging the first axial fan 21 and the second axial fan 22, the air supply volume of the fan can be greatly improved, the energy consumption of the fan (air conditioner indoor unit 100) can be reduced, 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.

[0056] For example, the first fan 21a (the first axial fan 21) is arranged obliquely upward so that the first fan 21a (the first axial fan 21) transports air obliquely upward, and the second fan 22a (the second axial fan 22) is arranged obliquely upward so that the second fan 22a (the second axial fan 22) transports air obliquely upward. Specifically, the first fan 21a (the first axial fan 21) is arranged upward leftward so as to transport air upward leftward, and the first fan 21a (the first axial fan 21) is arranged upward rightward so as to transport air upward rightward.

[0057] Alternatively, the angle α1 between the rotating axis of the first fan 21a and the vertical direction is greater than or equal to 70 degrees and less than or equal to 110 degrees, and the angle α2 between the rotating axis of the second fan 22a and the vertical direction is greater than or equal to 70 degrees and less than or equal to 110 degrees. In this way, the first fan 21a and the second fan 22a can have good air suction and blowing effects.

[0058] Further alternatively, the angle α1 between the rotating axis of the first fan 21a and the vertical direction is greater than or equal to 75 degrees and less than or equal to 85 degrees, and the angle α2 between the rotating axis of the second fan 22a and the vertical direction is greater than or equal to 75 degrees and less than or equal to 85 degrees. In this way, the first fan 21a and the second fan 22a can have better air suction and blowing effects.

[0059] As shown in Figure 3 , Figure 4 and Figure 6 , the fan comprises a plurality of first axial fans 21 and a plurality of second axial fans 22, the plurality of first axial fans 21 are coaxially arranged, and the plurality of second axial fans 22 are coaxially arranged. That is, the first fan 21a comprises a plurality of first axial fans 21, and the second fan 22a comprises a plurality of second axial fans 22.

[0060] In this way, the fan has a multi-stage fan structure. The multi-stage fan structure can significantly increase the static pressure and dynamic pressure of the airflow outlet, so that the airflow can effectively overcome the resistance of the heat exchanger to achieve long-distance air supply, thereby making the cold air and hot air blown by the air conditioner indoor unit 100 more fully and more quickly cover the entire room, and further improving the refrigeration and heating effects of the air conditioner indoor unit 100.

[0061] As shown in Figure 3 , Figure 4 and Figure 6 , the air conditioner indoor unit 100 further comprises a first bearing support 71 and a first bearing 72, and the plurality of first axial fans 21 (the first fan 21a) comprises a first shaft 211, a first motor 212 and a plurality of first axial fan blade groups 213. The first bearing support 71 is arranged on the top plate 17 of the cabinet 1, and the first bearing 72 is arranged on the first bearing support 71.

[0062] The first shaft 211 is supported by the first bearing 72 and is arranged obliquely. The first motor 212 is connected to the first shaft 211. The first axial flow fan 21 (first fan 21a) comprises the first shaft 211, the first motor 212 and a plurality of first axial flow blade groups 213 arranged along the axial direction of the first shaft 211. The first bearing support 71 is arranged to make the first axial flow fan 21 (first fan 21a) more stable and easier to install.

[0063] As shown in Figure 3 , Figure 4 and Figure 6 , the air conditioner indoor unit 100 further comprises a second bearing support 73 and a second bearing 74, and the second axial flow fan 22 (second fan 22a) comprises a second shaft 221, a second motor 222 and a plurality of second axial flow blade groups 223. The second bearing support 73 is arranged on the top plate 17 of the casing 1, and the second bearing 74 is arranged on the second bearing support 73.

[0064] The second shaft 221 is supported by the second bearing 74 and is arranged obliquely. The second motor 222 is connected to the second shaft 221. The second axial flow fan 22 (second fan 22a) comprises the second shaft 221, the second motor 222 and a plurality of second axial flow blade groups 223 arranged along the axial direction of the second shaft 221. The second bearing support 73 is arranged to make the second axial flow fan 22 (second fan 22a) more stable and easier to install.

[0065] Optionally, the first motor 212 is located between the plurality of first axial flow blade groups 213 and the plurality of second axial flow blade groups 223 in the length direction of the casing 1. The second motor 222 is located between the plurality of first axial flow blade groups 213 and the plurality of second axial flow blade groups 223 in the length direction of the casing 1. In this way, the first motor 212 does not block the airflow output by the plurality of first axial flow blade groups 213, and the second motor 222 does not block the airflow output by the plurality of second axial flow blade groups 223, so that the structure of the air conditioner indoor unit 100 is more reasonable.

[0066] Optionally, the first bearing support 71 and the first bearing 72 are located between the plurality of first axial flow blade groups 213 and the plurality of second axial flow blade groups 223 in the length direction of the casing 1. The second bearing support 73 and the second bearing 74 are located between the plurality of first axial flow blade groups 213 and the plurality of second axial flow blade groups 223 in the length direction of the casing 1. In this way, the structure of the plurality of first axial flow fans 21 and the plurality of second axial flow fans 22 is more compact, and when the plurality of first axial flow fans 21 and the plurality of second axial flow fans 22 are arranged in the flow guide cover, the first bearing support 71 and the second bearing support 73 do not interfere with the flow guide cover.

[0067] As shown in Figure 3As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1.

[0068] As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1. Figure 3 , Figure 4 and Figure 6 As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1.

[0069] As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1.

[0070] As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1. Figure 3 , Figure 4 and Figure 6 As shown in FIG. 1, the first side plate 11, the plurality of first axial flow blade groups 213, the first bearing 72, the first motor 212, the second motor 222, the second bearing 74, the plurality of second axial flow blade groups 223 and the second side plate 12 are arranged in sequence in the length direction of the casing 1.

[0071] When the first fan 21a and the second fan 22a are arranged obliquely upward, the first fan 21a and the second fan 22a transport air obliquely upward, so that a part of the air transported by the first fan 21a can not be heat-exchanged with the heat exchanger (the first heat exchange portion 31), and a part of the air transported by the second fan 22a can not be heat-exchanged with the heat exchanger (the fourth heat exchange portion 42).

[0072] By setting the first air deflector 83 and the second air deflector 84, the air delivered by the first air blower 21a can flow horizontally or obliquely downward, and the air delivered by the second air blower 22a can flow horizontally or obliquely downward. Thus, the air delivered by the first air blower 21a can be fully exchanged with the heat exchanger (the first heat exchange portion 31), and the air delivered by the second air blower 22a can be fully exchanged with the heat exchanger (the fourth heat exchange portion 42).

[0073] For example, the first air deflector 83 is horizontally arranged at the upper portion of the first air deflector cover 81, and extends from the first air deflector cover 81 to the direction adjacent to the first side plate 11 along the length direction of the casing 1. The second air deflector 84 is horizontally arranged at the upper portion of the second air deflector cover 82, and extends from the second air deflector cover 82 to the direction adjacent to the second side plate 12 along the length direction of the casing 1.

[0074] Thus, the air delivered by the first air blower 21a and the second air blower 22a can flow horizontally, so that not only the air delivered by the first air blower 21a and the second air blower 22a can be fully exchanged with the heat exchanger, but also the air delivered by the first air blower 21a can be more easily discharged through the first air outlet 111, and the air delivered by the second air blower 22a can be more easily discharged through the second air outlet 121.

[0075] Alternatively, the first air deflector 83 and the second air deflector 84 can both be arc-shaped plates. Thus, the air delivered by the first air blower 21a and the second air blower 22a can flow more horizontally or obliquely downward.

[0076] As shown in Figure 3 , Figure 5 and Figure 6 , the heat exchanger includes the first heat exchanger 3 and the second heat exchanger 4. The first heat exchanger 3 is located between the air outlet side of the first air blower 21a (the first axial flow fan 21) and the first air outlet 111, or the first heat exchanger 3 is located between the air inlet 14 of the casing 1 and the air inlet side of the first air blower 21a (the first axial flow fan 21). The second heat exchanger 4 is located between the air outlet side of the second air blower 22a (the second axial flow fan 22) and the second air outlet 121, or the second heat exchanger 4 is located between the air inlet 14 and the air inlet side of the second air blower 22a (the second axial flow fan 22). Thus, the structure of the air conditioner indoor unit 100 can be more reasonable.

[0077] As shown in Figure 3 , Figure 5 and Figure 6As shown, the first heat exchanger 3 comprises a first heat exchange portion 31 and a second heat exchange portion 32, the first heat exchange portion 31 is located between the air outlet side of the first fan 21a (the first axial fan 21) and the first air outlet 111, and the second heat exchange portion 32 is located between the air inlet 14 and the air inlet side of the first fan 21a (the first axial fan 21). The second heat exchanger 4 comprises a third heat exchange portion 41 and a fourth heat exchange portion 42, the third heat exchange portion 41 is located between the air inlet 14 and the air inlet side of the second fan 22a (the second axial fan 22), and the fourth heat exchange portion 42 is located between the air outlet side of the second fan 22a (the second axial fan 22) and the second air outlet 121.

[0078] Air enters the casing 1 from the air inlet 14, and is divided into a first air flow and a second air flow under the suction of the first fan 21a (the first axial fan 21) and the second fan 22a (the second axial fan 22). The first air flow first flows through the second heat exchange portion 32 and exchanges heat with the second heat exchange portion 32. The first air flow after heat exchange is sucked into the first fan 21a (the first axial fan 21), and then the first air flow is output by the first fan 21a (the first axial fan 21) and exchanges heat with the first heat exchange portion 31, so as to realize secondary heat exchange.

[0079] The second air flow first flows through the third heat exchange portion 41 and exchanges heat with the third heat exchange portion 41. The second air flow after heat exchange is sucked into the second fan 22a (the second axial fan 22), and then the second air flow is output by the second fan 22a (the second axial fan 22) and exchanges heat with the fourth heat exchange portion 42, so as to realize secondary heat exchange. In this way, the heat exchange efficiency of the first heat exchanger 3 and the second heat exchanger 4 can be further improved, thereby further improving the refrigeration and heating effect of the air conditioner indoor unit 100.

[0080] As shown in Figure 3 , Figure 5 and Figure 6 , each of the first heat exchange portion 31 and the second heat exchange portion 32 is obliquely arranged, and the first fan 21a (the first axial fan 21) is located between the upper end portion 311 of the first heat exchange portion 31 and the upper end portion 321 of the second heat exchange portion 32 in the length direction of the casing 1. In this way, the structure of the air conditioner indoor unit 100 can be more compact and more reasonable.

[0081] Optionally, a first containing space is formed between the first heat exchange portion 31 and the second heat exchange portion 32, and at least a part of the first fan 21a (the first axial fan 21) is located in the first containing space. In this way, the structure of the air conditioner indoor unit 100 can be more compact and more reasonable.

[0082] As shown in Figure 3As shown in

[0083] As shown in Figure 3 、 Figure 5 and Figure 6 Each of the third heat exchange portion 41 and the fourth heat exchange portion 42 is obliquely arranged, and the second fan 22a (the second axial fan 22) is located between the upper end portion 411 of the third heat exchange portion 41 and the upper end portion 421 of the fourth heat exchange portion 42 in the length direction of the casing 1. Thus, the structure of the air conditioner indoor unit 100 can be more compact and reasonable.

[0084] Optionally, a second accommodating space is formed between the third heat exchange portion 41 and the fourth heat exchange portion 42, and at least a part of the second fan 22a (the second axial fan 22) is located in the second accommodating space. Thus, the structure of the air conditioner indoor unit 100 can be more compact and reasonable.

[0085] As shown in Figure 3 and Figure 6 The second fan 22a (the second axial fan 22) is located below the upper end portion 421 of the fourth heat exchange portion 42. Thus, the air output by the second fan 22a (the second axial fan 22) can be prevented from being directly discharged from the second air outlet 121 without being exchanged with the fourth heat exchange portion 42, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects.

[0086] As shown in Figure 3 and Figure 6 The first fan 21a and the second fan 22a are arranged at intervals in the length direction of the casing 1, and the first heat exchange portion 31, the second heat exchange portion 32, the third heat exchange portion 41 and the fourth heat exchange portion 42 are arranged in sequence in the length direction of the casing 1.

[0087] The lower end portion 312 of the first heat exchange portion 31 and the lower end portion 322 of the second heat exchange portion 32 are in contact, so that the first heat exchanger 3 is V-shaped. Thus, the air can be prevented from flowing between the first heat exchange portion 31 and the second heat exchange portion 32, so as to prevent the first fan 21a (the first axial fan 21) from sucking the air which is not exchanged with the second heat exchange portion 32, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects.

[0088] The lower end 412 of the third heat exchange portion 41 and the lower end 422 of the fourth heat exchange portion 42 are in contact, so that the second heat exchanger 4 is in V shape. Thus, the air can be prevented from flowing between the third heat exchange portion 41 and the fourth heat exchange portion 42, so that the first fan 21a (the first axial fan 21) is prevented from sucking the air which is not exchanged with the third heat exchange portion 41, and the second fan 22a (the second axial fan 22) is prevented from sucking the air which is not exchanged with the third heat exchange portion 41, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects.

[0089] As shown in Figs. 1 and 2, the upper end 321 of the second heat exchange portion 32 and the upper end 411 of the third heat exchange portion 41 are in contact, and the first heat exchanger 3 and the second heat exchanger 4 are generally in W shape. Thus, the air can be prevented from flowing between the second heat exchange portion 32 and the third heat exchange portion 41, so that the first fan 21a (the first axial fan 21) is prevented from sucking the air which is not exchanged with the second heat exchange portion 32, and the second fan 22a (the second axial fan 22) is prevented from sucking the air which is not exchanged with the third heat exchange portion 41, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects. Figure 3 Figure 5 Figure 6 As shown in Figs. 1 and 2, the upper end 321 of the second heat exchange portion 32 and the upper end 411 of the third heat exchange portion 41 are in contact, and the first heat exchanger 3 and the second heat exchanger 4 are generally in W shape. Thus, the air can be prevented from flowing between the second heat exchange portion 32 and the third heat exchange portion 41, so that the first fan 21a (the first axial fan 21) is prevented from sucking the air which is not exchanged with the second heat exchange portion 32, and the second fan 22a (the second axial fan 22) is prevented from sucking the air which is not exchanged with the third heat exchange portion 41, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effects.

[0090] Alternatively, the lower end 312 of the first heat exchange portion 31 and the lower end 322 of the second heat exchange portion 32 are connected, the lower end 412 of the third heat exchange portion 41 and the lower end 422 of the fourth heat exchange portion 42 are connected, and the upper end 321 of the second heat exchange portion 32 and the upper end 411 of the third heat exchange portion 41 are connected. Thus, the structure of the first heat exchanger 3 and the second heat exchanger 4 can be more stable.

[0091] Alternatively, the angle θ1 between the first heat exchange portion 31 and the vertical direction is greater than or equal to 30 degrees and less than or equal to 45 degrees, and the angle θ2 between the fourth heat exchange portion 42 and the vertical direction is greater than or equal to 30 degrees and less than or equal to 45 degrees. Thus, the heat exchange capacity of the first heat exchange portion 31 and the fourth heat exchange portion 42 can be improved. Moreover, when the first fan 21a is covered by the first air guide cover 81 and the second fan 22a is covered by the second air guide cover 82, the whistling caused by the small gap between the first heat exchange portion 31 and the first air guide cover 81 and the whistling caused by the small gap between the fourth heat exchange portion 42 and the second air guide cover 82 can be avoided, so as to reduce the operation noise of the air conditioner indoor unit 100.

[0092] ​​Further optionally, the first heat exchange portion 31 and the vertical direction angle θ1 is greater than or equal to 36 degrees and less than or equal to 39 degrees, and the fourth heat exchange portion 42 and the vertical direction angle θ2 is greater than or equal to 36 degrees and less than or equal to 39 degrees. Thereby, the heat exchange capacity of the first heat exchange portion 31 and the fourth heat exchange portion 42 can be further improved. Moreover, the whistling caused by the too small gap between the first heat exchange portion 31 and the first air deflector 81 can be further avoided, and the whistling caused by the too small gap between the fourth heat exchange portion 42 and the second air deflector 82 can be further avoided, thereby further reducing the operation noise of the air conditioner indoor unit 100.

[0093] Optionally, the second heat exchange portion 32 and the vertical direction angle β1 is greater than or equal to 30 degrees and less than or equal to 45 degrees, and the third heat exchange portion 41 and the vertical direction angle β2 is greater than or equal to 30 degrees and less than or equal to 45 degrees. Thereby, the heat exchange capacity of the second heat exchange portion 32 and the third heat exchange portion 41 can be improved. Moreover, when the first fan 21a is provided with the first air deflector 81 and the second fan 22a is provided with the second air deflector 82, the whistling caused by the too small gap between the second heat exchange portion 32 and the first air deflector 81 can be avoided, and the whistling caused by the too small gap between the third heat exchange portion 41 and the second air deflector 82 can be avoided, thereby reducing the operation noise of the air conditioner indoor unit 100.

[0094] Further optionally, the second heat exchange portion 32 and the vertical direction angle β1 is greater than or equal to 36 degrees and less than or equal to 39 degrees, and the third heat exchange portion 41 and the vertical direction angle β2 is greater than or equal to 36 degrees and less than or equal to 39 degrees. Thereby, the heat exchange capacity of the second heat exchange portion 32 and the third heat exchange portion 41 can be further improved. Moreover, the whistling caused by the too small gap between the second heat exchange portion 32 and the first air deflector 81 can be further avoided, and the whistling caused by the too small gap between the third heat exchange portion 41 and the second air deflector 82 can be further avoided, thereby further reducing the operation noise of the air conditioner indoor unit 100.

[0095] Optionally, the difference between the first heat exchange portion 31 and the vertical direction angle θ1 and the second heat exchange portion 32 and the vertical direction angle β1 is less than or equal to 5 degrees, and the difference between the fourth heat exchange portion 42 and the vertical direction angle θ2 and the third heat exchange portion 41 and the vertical direction angle β2 is less than or equal to 5 degrees.

[0096] That is, the included angle θ1 can be greater than the included angle β1, θ1-β1 is less than or equal to 5 degrees, or the included angle β1 can be greater than the included angle θ1, β1-θ1 is less than or equal to 5 degrees. The included angle θ2 can be greater than the included angle β2, θ2-β2 is less than or equal to 5 degrees, or the included angle β2 can be greater than the included angle θ2, β2-θ2 is less than or equal to 5 degrees. In this way, not only can the heat exchange capacity of the first heat exchanger 3 and the second heat exchanger 4 be further improved, but also the size of the first heat exchanger 3 and the second heat exchanger 4 in the length direction and the height direction of the casing 1 can be effectively controlled, so as to effectively control the length and the height of the casing 1 and the air conditioner indoor unit 100.

[0097] Optionally, the included angle γ1 between the first air deflector 83 and the first heat exchange part 31 is greater than 0 degrees and less than or equal to 60 degrees, and the included angle γ2 between the second air deflector 84 and the fourth heat exchange part 42 is greater than 0 degrees and less than or equal to 60 degrees.

[0098] In this way, the first air deflector 83 can more fully guide the air output by the first fan 21a to the first heat exchange part 31, so that the air output by the first fan 21a is more fully exchanged with the first heat exchange part 31. The second air deflector 84 can more fully guide the air output by the second fan 22a to the fourth heat exchange part 42, so that the air output by the second fan 22a is more fully exchanged with the fourth heat exchange part 42.

[0099] As shown in FIG. 1, the first air deflector 83 is arranged on the first heat exchange part 31, and the second air deflector 84 is arranged on the fourth heat exchange part 42. Figure 6 As shown in FIG. 1, the first part 313 of the first heat exchange part 31 is opposite to the first air deflection cavity 811 of the first air deflector 81 in the axial direction of the first fan 21a, and the axial direction of the first fan 21a is the extension direction of the rotation axis of the first fan 21a. The second part 323 of the second heat exchange part 32 is opposite to the first air deflection cavity 811 in the axial direction of the first fan 21a. That is, the first plane is perpendicular to the axial direction of the first fan 21a, and the projection of the first air deflection cavity 811 on the first plane along the axial direction of the first fan 21a is the first projection. The projection of the part of the first heat exchange part 31 other than the first part 313 on the first plane along the axial direction of the first fan 21a is located outside the first projection, and the projection of the part of the second heat exchange part 32 other than the second part 323 on the first plane along the axial direction of the first fan 21a is located outside the first projection.

[0100] The first part 313 has a length of L1 in the inclined direction of the first heat exchange section 31, and the second part 323 has a length of L2 in the inclined direction of the second heat exchange section 32. The diameter of the first fan 21a is R1, 2 / 3R1≤L1, and 2 / 3R1≤L2. This allows for a sufficiently large overlap area between the first heat exchange section 31 and the second heat exchange section 32 and the first fan 21a (first air guide cavity 811), ensuring sufficient heat exchange between the air drawn in by the first fan 21a and the second heat exchange section 32, and between the air output by the first fan 21a and the first heat exchange section 31. Furthermore, it allows for sufficient distance between the inlet of the first fan 21a and the second part 323, and sufficient distance between the outlet of the first fan 21a and the first part 313, thereby reducing the operating noise of the indoor unit 100 of the air conditioner.

[0101] like Figure 6 As shown, the third portion 413 of the third heat exchange section 41 is opposite to the second air guide cavity 821 of the second air guide shroud 82 in the axial direction of the second fan 22a, where the axial direction of the second fan 22a is the extension direction of the rotation axis of the second fan 22a. The fourth portion 423 of the fourth heat exchange section 42 is opposite to the second air guide cavity 821 in the axial direction of the second fan 22a. That is, the second plane is perpendicular to the axial direction of the second fan 22a, and the projection of the second air guide cavity 821 along the axial direction of the second fan 22a onto the second plane is the second projection. The projection of the portion of the third heat exchange section 41 other than the third portion 413 along the axial direction of the second fan 22a onto the second plane is located outside the second projection, and the projection of the portion of the fourth heat exchange section 42 other than the fourth portion 423 along the axial direction of the second fan 22a onto the second plane is also located outside the second projection.

[0102] The length of the third part 413 in the inclined direction of the third heat exchange section 41 is L3, and the length of the fourth part 423 in the inclined direction of the fourth heat exchange section 42 is L4. The diameter of the second fan 22a is R2, 2 / 3R2≤L3, and 2 / 3R2≤L4. This allows the third heat exchange section 41 and the fourth heat exchange section 42 to have a sufficiently large overlap area with the second fan 22a (second air guide cavity 821), ensuring sufficient heat exchange between the air drawn in by the second fan 22a and the third heat exchange section 41, and between the air output by the second fan 22a and the fourth heat exchange section 42. Furthermore, it allows for sufficient distance between the inlet of the second fan 22a and the third part 413, and sufficient distance between the outlet of the second fan 22a and the fourth part 423, thereby reducing the operating noise of the indoor unit 100.

[0103] Optionally, L1≤5 / 4R1, L2≤5 / 4R1, L3≤5 / 4R2, and L4≤5 / 4R2. This avoids the first heat exchanger 31, the second heat exchanger 32, the third heat exchanger 41, and the fourth heat exchanger 42 from being too large, thereby reducing the assembly difficulty of the first heat exchanger 31, the second heat exchanger 32, the third heat exchanger 41, and the fourth heat exchanger 42, reducing the manufacturing cost of the air conditioner indoor unit 100, and effectively controlling the size of the air conditioner indoor unit 100.

[0104] like Figure 3 and Figure 5 As shown, the indoor unit 100 of the air conditioner further includes a first drip tray 5, which includes a first plate 51 and a second plate 52. The lower end 511 of the first plate 51 and the lower end 521 of the second plate 52 are connected. The lower end 312 of the first heat exchange section 31 and the lower end 322 of the second heat exchange section 32 are located between the upper end 512 of the first plate 51 and the upper end 522 of the second plate 52 in the length direction of the casing 1. This allows condensate dripping from the first heat exchange section 31 and the second heat exchange section 32 to be collected in the first drip tray 5.

[0105] like Figure 3 and Figure 5 As shown, the indoor unit 100 of the air conditioner further includes a second drip tray 6, which includes a third plate 61 and a fourth plate 62. The lower end 611 of the third plate 61 and the lower end 621 of the fourth plate 62 are connected. The lower end 412 of the third heat exchange section 41 and the lower end 422 of the fourth heat exchange section 42 are located between the upper end 612 of the third plate 61 and the upper end 622 of the fourth plate 62 in the length direction of the casing 1. This allows condensate dripping from the third heat exchange section 41 and the fourth heat exchange section 42 to be collected in the second drip tray 6.

[0106] Optionally, the upper end 522 of the second plate 52 is connected to the upper end 612 of the third plate 61. This further ensures that the first drip tray 5 and the second drip tray 6 can collect the condensate falling from the second heat exchange section 32 and the third heat exchange section 41, thereby preventing the condensate from flowing outside the air conditioner indoor unit 100 and corroding the ceiling, walls, etc. of the adjacent air conditioner indoor unit 100.

[0107] like Figure 3 and Figure 5 As shown, the first water receiving tray 5 is generally V-shaped, and the second water receiving tray 6 is generally V-shaped. The upper end 522 of the second plate 52 is connected to the upper end 612 of the third plate 61, so that the first water receiving tray 5 and the second water receiving tray 6 generally form a W-shape.
