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

[0025] An air conditioner indoor unit 100 according to an embodiment of the present application is described below with reference to the drawings. As shown in Figures 1-6 the air conditioner indoor unit 100 according to an embodiment of the present application includes a casing 1, a first fan 21, a second fan 22, a cross-flow fan 23, and a heat exchanger 3, the heat exchanger 3 being provided in the casing 1.

[0026] The casing 1 includes a first side plate 11, a second side plate 12, a front panel 13, and a rear plate 14. The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the casing 1, and the front panel 13 and the rear plate 14 are oppositely arranged in the width direction of the casing 1. The first side plate 11 is provided with a first air outlet 111, the second side plate 12 is provided with a second air outlet 121, and the front panel 13 is provided with a third air outlet 131.

[0027] The air outlet side of the first fan 21 faces the first air outlet 111, and the air outlet side of the second fan 22 faces the second air outlet 121. The first fan 21 is one of an axial fan and a centrifugal fan, and the second fan 22 is one of an axial fan and a centrifugal fan. The air outlet side of the cross-flow fan 23 faces the third air outlet 131, and the cross-flow fan 23 is located between the first fan 21 and the second fan 22 in the length direction of the cabinet 1.

[0028] The air conditioner indoor unit 100 according to the embodiment of the present application can increase the air outlet area to increase the air outlet volume, and can increase the air outlet direction to make the cold air and the hot air blown by the air conditioner indoor unit 100 cover the whole room more fully and more quickly, thereby improving the refrigeration and heating effects. Especially when the length of the cabinet 1 is small, the first air outlet 111 and the second air outlet 121 can effectively increase the air outlet volume, thereby improving the refrigeration and heating effects.

[0029] Further, 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 arranging the second air outlet 121 on the second side plate 12, thereby avoiding the cold air and the hot air blown from the first air outlet 111 and the second air outlet 121 directly blowing on the user. Thus, the air flow directly blowing on the user can be effectively reduced, thereby making the user feel more comfortable.

[0030] The air conditioner indoor unit 100 according to the embodiment of the present application can further increase the air outlet volume of each air outlet by arranging the first fan 21, the second fan 22 and the cross-flow fan 23 facing one air outlet respectively, thereby making the cold air and the hot air blown by the air conditioner indoor unit 100 cover the whole room more fully and more quickly, and further improving the refrigeration and heating effects of the air conditioner indoor unit 100.

[0031] Therefore, the air conditioner indoor unit 100 according to the embodiment of the present application has the advantages of good refrigeration and heating effects, effectively reducing the air flow directly blowing on the user, improving the comfort of the user, and the like.

[0032] As shown in Figures 1-6 The air conditioner indoor unit 100 according to the embodiment of the present application includes a cabinet 1, a first fan 21, a second fan 22, a cross-flow fan 23 and a heat exchanger 3, and the heat exchanger 3 is arranged in the cabinet 1. The cabinet 1 includes a first side plate 11, a second side plate 12, a front plate 13, a back plate 14, a bottom plate 15 and a top plate 18.

[0033] 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 bottom plate 15 and the top plate 18 are arranged opposite to each other in the height direction of the casing 1. The air inlet 16 of the casing 1 is arranged on at least one of the bottom plate 15 and the rear plate 14.

[0034] 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 width direction of the casing 1 can be consistent with the front-rear direction, and the height direction of the casing 1 can be consistent with the up-down direction. The left-right direction is indicated by an arrow A in Figure 3 , the front-rear direction is indicated by an arrow B in Figure 1 , and the up-down direction is indicated by an arrow C in Figure 1 .

[0035] As shown in Figure 1 and Figures 4-6 , 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 air outlet side of the first fan 21 are matched, and the second air outlet 121 and the air outlet side of the second fan 22 are matched, so that the first fan 21 and the second fan 22 are conveniently installed in the casing 1.

[0036] Alternatively, the first air outlet 111 extends in the width direction of the casing 1, and the second air outlet 121 extends in the width direction of the casing 1. In this way, the air outlet area of the air conditioner indoor unit 100 can be increased, and thus the air outlet volume of the air conditioner indoor unit 100 can be increased, so as to further improve the refrigeration and heating effect of the air conditioner indoor unit 100.

[0037] As shown in Figure 1 and Figures 4-6 , the third air outlet 131 is arranged at the upper portion of the front plate 13. In this way, the third air outlet 131 and the air outlet side of the cross-flow fan 23 are matched, so that the cross-flow fan 23 is conveniently installed in the casing 1. The third air outlet 131 extends in the length direction of the casing 1. In this way, the air outlet area of the air conditioner indoor unit 100 can be increased, and thus the air outlet volume of the air conditioner indoor unit 100 can be increased, so as to further improve the refrigeration and heating effect of the air conditioner indoor unit 100.

[0038] As shown in Figure 1 and Figures 4-6As shown, the air conditioner indoor unit 100 further comprises a first air deflector 171 and a second air deflector 172. The first air deflector 171 is rotatably provided at the first air outlet 111 of the first side plate 11 between a first closed position and a first air deflection position, and the rotation axis of the first air deflector 171 extends along the width direction or the height direction of the casing 1. The second air deflector 172 is rotatably provided at the second air outlet 121 of the second side plate 12 between a second closed position and a second air deflection position, and the rotation axis of the second air deflector 172 extends along the width direction or the height direction of the casing 1.

[0039] When the air conditioner indoor unit 100 is in heating mode, the first air deflector 171 in the first air deflection position extends obliquely downward or horizontally (is arranged), and the second air deflector 172 in the second air deflection position extends obliquely downward or horizontally (is arranged). When the first air deflector 171 (the second air deflector 172) extends obliquely downward, the upper end of the first air deflector 171 (the second air deflector 172) is adjacent to the first side plate 11 (the second side plate 12) in the length direction of the casing 1 relative to the lower end of the first air deflector 171 (the second air deflector 172).

[0040] In other words, when the air conditioner indoor unit 100 is in heating mode, the angle between the first air deflector 171 in the first air deflection position and the vertically downward direction is greater than 0 degrees and less than or equal to 90 degrees. The angle between the second air deflector 172 in the second air deflection position and the vertically downward direction is greater than 0 degrees and less than or equal to 90 degrees. Thus, when in heating mode, the first air deflector 171 and the second air deflector 172 can make the hot air flow downward to form "carpet wind", so that the hot air more fully and more quickly covers the entire room, so as to further improve the heating effect.

[0041] When the air conditioner indoor unit 100 is in cooling mode, the first air deflector 171 in the first air deflection position extends obliquely upward or horizontally (is arranged), and the second air deflector 172 in the second air deflection position extends obliquely upward or horizontally (is arranged). When the first air deflector 171 (the second air deflector 172) extends obliquely upward, the upper end of the first air deflector 171 (the second air deflector 172) is away from the first side plate 11 (the second side plate 12) in the length direction of the casing 1 relative to the lower end of the first air deflector 171 (the second air deflector 172).

[0042] In other words, when the air conditioner indoor unit 100 is in cooling mode, the angle between the first air deflector 171 in the first air deflection position and the vertically upward direction is greater than 0 degrees and less than or equal to 90 degrees. The angle between the second air deflector 172 in the second air deflection position and the vertically upward direction is greater than 0 degrees and less than or equal to 90 degrees. Thus, the comfort of the user can be further improved.

[0043] AsFigure 1 And Figures 4-6 As shown in FIGS. 1 and 2, the air conditioner indoor unit 100 further includes a first support 41 and a first adjustment member 42, each of which is provided to the first side panel 11. The first support 41 is connected to the first air deflector 171. At least a portion of the first adjustment member 42 is movably provided in the length direction of the cabinet 1, and the at least a portion of the first adjustment member 42 is connected to the first air deflector 171.

[0044] That is, the first adjustment member 42 can be movably provided in the length direction of the cabinet 1 as a whole. In addition, a portion of the first adjustment member 42 is movably provided in the length direction of the cabinet 1 so that the portion of the first adjustment member 42 is telescopically provided in the length direction of the cabinet 1 with respect to another portion of the first adjustment member 42.

[0045] As shown in FIGS. 1 and 2, the air conditioner indoor unit 100 further includes a second support 43 and a second adjustment member 44, each of which is provided to the second side panel 12. The second support 43 is connected to the second air deflector 172. At least a portion of the second adjustment member 44 is movably provided in the length direction of the cabinet 1, and the at least a portion of the second adjustment member 44 is connected to the second air deflector 172. Figure 1 Figures 4-6 That is, the second adjustment member 44 can be movably provided in the length direction of the cabinet 1 as a whole. In addition, a portion of the second adjustment member 44 is movably provided in the length direction of the cabinet 1 so that the portion of the second adjustment member 44 is telescopically provided in the length direction of the cabinet 1 with respect to another portion of the second adjustment member 44.

[0046] That is, the second adjustment member 44 can be movably provided in the length direction of the cabinet 1 as a whole. In addition, a portion of the second adjustment member 44 is movably provided in the length direction of the cabinet 1 so that the portion of the second adjustment member 44 is telescopically provided in the length direction of the cabinet 1 with respect to another portion of the second adjustment member 44.

[0047] Accordingly, the inclination direction of the first air deflector 171 can be changed, and the included angle of the first air deflector 171 with the vertically downward direction and the vertically upward direction can be changed by moving the at least a portion of the first adjustment member 42 in the length direction of the cabinet 1. Also, the inclination direction of the second air deflector 172 can be changed, and the included angle of the second air deflector 172 with the vertically downward direction and the vertically upward direction can be changed by moving the at least a portion of the second adjustment member 44 in the length direction of the cabinet 1.

[0048] ​For example, when the air conditioner indoor unit 100 is not running, the first air deflector 171 and the second air deflector 172 can be arranged substantially vertically. When the air conditioner indoor unit 100 is heating, the at least one portion of the first adjusting member 42 moves along the length direction of the casing 1 toward the direction adjacent to the first side plate 11 (the second side plate 12) so as to make the first air deflector 171 extend obliquely downward, and the at least one portion of the second adjusting member 44 moves along the length direction of the casing 1 toward the direction adjacent to the second side plate 12 (the first side plate 11) so as to make the second air deflector 172 extend obliquely downward.

[0049] When the air conditioner indoor unit 100 is cooling, the at least one portion of the first adjusting member 42 moves along the length direction of the casing 1 toward the direction away from the first side plate 11 (the second side plate 12) so as to make the first air deflector 171 extend obliquely upward, and the at least one portion of the second adjusting member 44 moves along the length direction of the casing 1 toward the direction away from the second side plate 12 (the first side plate 11) so as to make the second air deflector 172 extend obliquely upward.

[0050] Optionally, the at least one portion of the first adjusting member 42 is hinged with the first air deflector 171, and the first support member 41 is hinged with the first air deflector 171. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable. The at least one portion of the second adjusting member 44 is hinged with the second air deflector 172, and the second support member 43 is hinged with the second air deflector 172. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0051] As shown in Figure 1 and Figures 4-6 , the rotation axis of the first air deflector 171 extends along the width direction of the casing 1. The air conditioner indoor unit 100 comprises two first support members 41, which are arranged spaced apart along the width direction of the casing 1. The first adjusting member 42 is located between the two first support members 41 in the width direction of the casing 1, and the first adjusting member 42 is located above the two first support members 41. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0052] In particular, the at least one portion of the first adjusting member 42 is hinged with the upper end of the first air deflector 171, and each first support member 41 is hinged with the lower end of the first air deflector 171. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0053] As shown in Figure 1 and Figures 4-6As shown, the rotation axis of the second air deflector 172 extends along the width direction of the casing 1. The air conditioner indoor unit 100 comprises two second support members 43, which are arranged in the width direction of the casing 1. The second adjustment member 44 is located between the two second support members 43 in the width direction of the casing 1, and is located above the two second support members 43. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0054] Specifically, the at least one part of the second adjustment member 44 is hinged to the upper end of the second air deflector 172, and each second support member 43 is hinged to the lower end of the second air deflector 172. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0055] Optionally, the air outlet side of the first fan 21 is opposite to the first air outlet 111 in the length direction of the casing 1, the air outlet side of the second fan 22 is opposite to the second air outlet 121 in the length direction of the casing 1, and the air outlet side of the cross-flow fan 23 is opposite to the third air outlet 131 in the width direction of the casing 1. In this way, the air volume of the first air outlet 111, the second air outlet 121 and the third air outlet 131 can be further improved, 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, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100.

[0056] Optionally, the first fan 21 is an axial fan, and the second fan 22 is an axial fan. 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 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 can more fully and more quickly cover the entire room, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100.

[0057] Optionally, the air conditioner indoor unit 100 further comprises a third air deflector, which is rotatably arranged at the lower edge of the third air outlet 131 of the front panel 13 between the third closed position and the third air deflection position, and the rotation axis of the third air deflector extends along the length direction of the casing 1. The third air deflector located at the third air deflection position has an included angle with the vertically upward direction greater than 0 degrees and less than or equal to 90 degrees.

[0058] In other words, the third air deflector is installed on the front panel 13, and when the third air deflector is in the third closed position, the lower end of the third air deflector is rotatably connected to the front panel 13 and is located at the lower edge of the third air outlet 131. When the third air deflector is in the third air deflection position, the third air deflector extends obliquely upward and forward from the front panel 13 or extends horizontally (is arranged). Thus, when cooling, the third air deflector can make the cold air flow upward and forward, so as to not only avoid the cold air directly blowing on the user, so as to further improve the comfort of the user, but also make the cold air more fully and quickly cover the entire room, so as to further improve the cooling effect.

[0059] As Figures 1-3 shown, in an embodiment of the present application, the heat exchanger 3 includes a lower heat exchange portion 31 and a front heat exchange portion 32. The lower heat exchange portion 31 is located between the air inlet 16 and the air inlet side of each of the first fan 21, the second fan 22, and the cross-flow fan 23 in the height direction of the casing 1. The front heat exchange portion 32 is located between the air outlet side of the cross-flow fan 23 and the third air outlet 131 in the width direction of the casing 1.

[0060] The air entering the casing 1 from the air inlet 16 first flows through the lower heat exchange portion 31 and exchanges heat with the lower heat exchange portion 31. Part of the air after heat exchange is sucked by the cross-flow fan 23, and then the part of the air is output by the cross-flow fan 23 and exchanges heat with the front heat exchange portion 32, so as to realize secondary heat exchange. Thus, the heat exchange efficiency of the heat exchanger 3 can be further improved, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100. The remaining part of the air after heat exchange is respectively sucked by the first fan 21 and the second fan 22, and then the part of the air is respectively delivered to the room from the first air outlet 111 and the second air outlet 121.

[0061] As Figures 1-3 shown, the heat exchanger 3 further includes a first side heat exchange portion 33 and a second side heat exchange portion 34. The first side heat exchange portion 33 is located between the air outlet side of the first fan 21 and the first air outlet 111, and the second side heat exchange portion 34 is located between the air outlet side of the second fan 22 and the second air outlet 121.

[0062] The air entering the casing 1 from the air inlet 16 first flows through the lower heat exchange portion 31 and exchanges heat with the lower heat exchange portion 31. Part of the air after heat exchange is sucked by the cross-flow fan 23, and then the part of the air is output by the cross-flow fan 23 and exchanges heat with the front heat exchange portion 32, so as to realize secondary heat exchange. Thus, the heat exchange efficiency of the heat exchanger 3 can be further improved, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100. The remaining part of the air after heat exchange is respectively sucked by the first fan 21 and the second fan 22, and then the part of the air is respectively delivered to the room from the first air outlet 111 and the second air outlet 121.

[0063] As shown in Figures 1-3 The lower heat exchange part 31 is horizontally or obliquely arranged, and has a first end part 311 and a second end part 312 opposite in the length direction of the cabinet 1. Each of the front heat exchange part 32, the first side heat exchange part 33 and the second side heat exchange part 34 is vertically or obliquely arranged.

[0064] The lower end part 321 of the front heat exchange part 32 is in contact with the front end part 313 of the lower heat exchange part 31, the lower end part 331 of the first side heat exchange part 33 is in contact with the first end part 311 of the lower heat exchange part 31, and the lower end part 341 of the second side heat exchange part 34 is in contact with the second end part 312 of the lower heat exchange part 31. In this way, the structure of the heat exchanger 3 can be more reasonable.

[0065] Alternatively, the lower end part 331 of the first side heat exchange part 33 is connected with the first end part 311 of the lower heat exchange part 31, the lower end part 341 of the second side heat exchange part 34 is connected with the second end part 312 of the lower heat exchange part 31, and the lower end part 321 of the front heat exchange part 32 is connected with the front end part 313 of the lower heat exchange part 31. In this way, the structure of the heat exchanger 3 can be more stable, and the heat exchanger 3 can be more easily assembled.

[0066] Specifically, the lower heat exchange part 31 is located above the air inlet 16, and is located below the first fan 21, the second fan 22 and the cross-flow fan 23. The first side plate 11, the first side heat exchange part 31, the first fan 21, the cross-flow fan 23, the second fan 22, the second side heat exchange part 32 and the second side plate 12 are arranged in sequence in the length direction of the cabinet 1.

[0067] As shown in Figures 1-3 The thickness direction of the front heat exchange part 32 is consistent with the width direction of the cabinet 1, and the thickness direction of each of the first side heat exchange part 33 and the second side heat exchange part 34 is consistent with the length direction of the cabinet 1. In this way, the front heat exchange part 32, the first side heat exchange part 33 and the second side heat exchange part 34 can have a larger heat exchange area, thereby improving the heat exchange efficiency of the heat exchanger 3.

[0068] As shown in Figure 1 and Figure 2 The air conditioner indoor unit 100 further comprises a water collecting tray 5, which comprises a first plate 51 and a second plate 52.

The included angle of the first plate 51 and the second plate 52 is greater than or equal to a preset value.

[0069] By making the included angle between the first plate 51 and the second plate 52 greater than or equal to a preset value, the water receiving tray 5 can be made flat overall, thereby reducing the height of the water receiving tray 5. This increases the dimension of the heat exchanger 3 in the height direction of the casing 1, thereby increasing the heat exchange area of ​​the heat exchanger 3, or reduces the installation difficulty of the heat exchanger 3 by increasing the housing space of the heat exchanger 3. In addition, while keeping the size of the heat exchanger 3 substantially unchanged, the height of the casing 1 and the indoor air conditioning unit 100 can be reduced, thereby reducing the space occupied by the casing 1 and the indoor air conditioning unit 100.

The third end 314 of the lower heat exchange section 31 is adjacent to the upper end 512 of the first plate 51 in the width direction of the housing 1, and the fourth end 315 of the lower heat exchange section 31 is adjacent to the upper end 522 of the second plate 52 in the width direction of the housing 1.

[0072] By setting the third plate 53 and the fourth plate 54, the depth of the drip tray 5 can be increased by increasing the size of the heat exchanger 3 in the height direction of the casing 1, increasing the housing space of the heat exchanger 3, or reducing the height of the casing 1 and the indoor unit 100 of the air conditioner, so as to increase the capacity of the drip tray 5 and prevent condensate from overflowing from the drip tray 5.

[0073] like Figure 1 and Figure 2 As shown, the first plate 51 is located in front of the second plate 52. The third end 314 (front end 313) of the lower heat exchange section 31 is generally flush with the upper end 512 of the first plate 51 in the width direction of the housing 1, and the fourth end 315 (rear end) of the lower heat exchange section 31 is generally flush with the upper end 522 of the second plate 52 in the width direction of the housing 1.

[0074] The third plate 53 is inclined and extends forward and upward from the upper end 512 of the first plate 51. The fourth plate 54 is inclined and extends backward and upward from the upper end 522 of the second plate 52. The upper end 532 of the third plate 53 and the upper end 542 of the fourth plate 54 are both located above the lower edge (lower surface) of the lower heat exchange section 31.
