[0034] Embodiments of the present application will be described in detail below, examples of which are shown in the 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.

[0035] The air conditioner indoor unit 100 according to an embodiment of the present application will be described below with reference to the drawings. As shown inFigures 1-5 As shown, the air conditioner indoor unit 100 according to the embodiment of the present application comprises a casing 1, a first fan 21, a second fan 22, a third fan 23 and a heat exchanger 3.

[0036] The casing 1 comprises a first side plate 11, a second side plate 12, a front plate 13 and a back 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 plate 13 and the back 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 (not shown in the figure), the second side plate 12 is provided with a second air outlet 121, and the front plate 13 is provided with a third air outlet 131.

[0037] The air outlet side of the first fan 21 faces the first air outlet, the air outlet side of the second fan 22 faces the second air outlet 121, and the air outlet side of the third fan 23 faces the third air outlet 131. The heat exchanger 3 is arranged in the casing 1.

[0038] The air conditioner indoor unit 100 according to the embodiment of the present application is provided with multiple air outlets (the first air outlet, the second air outlet 121 and the third air outlet 131), so as to not only increase the air outlet area to increase the air volume, but also increase the air outlet direction, 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 casing 1 is small, by arranging the first air outlet and the second air outlet 121, the air volume can be effectively improved to improve the refrigeration and heating effect.

[0039] Moreover, the air conditioner indoor unit 100 according to the embodiment of the present application is provided with the first air outlet on the first side plate 11 and the second air outlet 121 on the second side plate 12, so as to realize side air outlet to avoid the cold air and the hot air blown from the first air outlet and the second air outlet 121 directly blowing on the user. Thus, the air flow directly blowing on the user can be effectively reduced, so as to make the user feel more comfortable.

[0040] The air conditioner indoor unit 100 according to the embodiment of the present application is provided with the first fan 21, the second fan 22 and the third fan 23 respectively facing one air outlet, so as to further improve the air volume of each air outlet, 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 further improve the refrigeration and heating effect of the air conditioner indoor unit 100.

[0041] Therefore, the air conditioner indoor unit 100 according to the embodiment of the present application has the advantages of good refrigeration and heating effect, effectively reducing the air flow directly blowing on the user, improving the comfort of the user, etc.

[0042] As Figures 1-5As shown, the air conditioner indoor unit 100 according to the embodiment of the present application comprises a casing 1, a first fan 21, a second fan 22, a third fan 23 and a heat exchanger 3.

[0043] The casing 1 comprises a first side plate 11, a second side plate 12, a front plate 13, a back plate 14, a top plate 18 and a bottom plate 15. The first side plate 11 and the second side plate 12 are oppositely arranged in the length direction of the casing 1, the front plate 13 and the back plate 14 are oppositely arranged in the width direction of the casing 1, and the top plate 18 and the bottom plate 15 are oppositely arranged in the height direction of the casing 1. The first side plate 11 is provided with a first air outlet, the second side plate 12 is provided with a second air outlet 121, and the front plate 13 is provided with a third air outlet 131.

[0044] 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 shown by an arrow A in Figure 3 , the front-rear direction is shown by an arrow B in Figure 3 , and the up-down direction is shown by an arrow C in Figure 1 .

[0045] Optionally, the bottom plate 15 of the casing 1 can be provided with an air inlet 16.

[0046] As shown in Figure 5 , the back plate 14 comprises a back frame portion 143, an upper plate portion 141 and a lower plate portion 142. The upper plate portion 141 is arranged on the back frame portion 143, and the lower plate portion 142 is arranged on the back frame portion 143 and connected to the upper plate portion 141. The lower plate portion 142 is arranged obliquely, and the lower edge of the lower plate portion 142 is located in front of the upper edge of the lower plate portion 142. That is, the lower plate portion 142 extends forwardly and downwardly from the upper plate portion 141. The lower plate portion 142 is provided with the air inlet 16.

[0047] By extending the lower plate portion 142 forwardly and downwardly from the upper plate portion 141, the lower plate portion 142 can be prevented from being close to a wall or the like, so that air can enter the casing 1 through the air inlet 16 arranged on the lower plate portion 142. By arranging the air inlet 16 on both the bottom plate 15 and the lower plate portion 142, the air inlet direction and the air inlet area can be increased to increase the air inlet amount, and thus the air outlet amount can be increased, so that the cold air and the hot air blown out by the air conditioner indoor unit 100 can more fully and more quickly cover the entire room, and the refrigeration and heating effects can be improved.

[0048] The rear frame portion 143 provides a mounting space for the inclined lower plate portion 142. For example, the upper plate portion 141 can be adjacent to the rear edge of the rear frame portion 143 in the front-rear direction, and the lower edge of the lower plate portion 142 can be adjacent to the front edge of the rear frame portion 143 in the front-rear direction. Specifically, the rear edge of each of the first side plate 11, the second side plate 12, the top plate 18, and the bottom plate 15 is connected to the rear frame portion 143.

[0049] As shown in Figure 1 and Figure 2 , the first air outlet is provided at the upper portion of the first side plate 11, and the second air outlet 121 is provided at the upper portion of the second side plate 12. In this way, the first air outlet and the first fan 21 on the air outlet side are matched, and the second air outlet 121 and the second fan 22 on the air outlet side are matched, so that the first fan 21 and the second fan 22 can be installed in the cabinet 1.

[0050] As shown in Figure 1 and Figure 2 , each of the first air outlet and the second air outlet 121 extends in the width direction of the cabinet 1, and the third air outlet 131 extends in the length direction of the cabinet 1. In this way, the air outlet area of the air conditioner indoor unit 100 can be increased, and 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.

[0051] As shown in Figure 2 and Figure 3 , the air outlet side of the first fan 21 is opposite to the first air outlet in the length direction of the cabinet 1, the air outlet side of the second fan 22 is opposite to the second air outlet 121 in the length direction of the cabinet 1, and the air outlet side of the third fan 23 is opposite to the third air outlet 131 in the width direction of the cabinet 1. In this way, the air outlet volume of the first air outlet, 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, so as to further improve the refrigeration and heating effect of the air conditioner indoor unit 100.

[0052] That is, the air outlet side of the first fan 21 faces the first direction, the air outlet side of the second fan 22 faces the second direction, and the first direction is opposite to the second direction. The length direction of the cabinet 1 includes the first direction and the second direction. The air outlet side of the third fan 23 faces the third direction (for example, the forward direction), and the third direction is perpendicular to each of the first direction and the second direction.

[0053] As shown in Figure 2 and Figure 3 , the third fan 23 is located between the first fan 21 and the second fan 22 in the length direction of the cabinet 1. In this way, the structure of the air conditioner indoor unit 100 can be more reasonable.

[0054] Optionally, the first fan 21 is a centrifugal fan or an axial fan, the second fan 22 is a centrifugal fan or an axial fan, and the third fan 23 is a centrifugal fan or an axial fan. In this way, the first fan 21, the second fan 22 and the third fan 23 can have a greater air supply volume, and can achieve long-distance air supply, 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, and the refrigeration and heating effects of the air conditioner indoor unit 100 can be further improved.

[0055] As shown in Figure 4 The air conditioner indoor unit 100 further includes a first bearing support 61, a first bearing, a second bearing support 62, a second bearing, a third bearing support 63 and a third bearing. The first bearing support 61, the second bearing support 62 and the third bearing support 63 are arranged on the top plate 18, the first bearing is arranged on the first bearing support 61, the second bearing is arranged on the second bearing support 62, and the third bearing is arranged on the third bearing support 63.

[0056] The first shaft 211 of the first fan 21 is supported by the first bearing and extends along the width direction of the casing 1. The second shaft 221 of the second fan 22 is supported by the second bearing and extends along the width direction of the casing 1. The third shaft 231 of the third fan 23 is supported by the third bearing and extends along the length direction of the casing 1. In this way, the first fan 21, the second fan 22 and the third fan 23 can be more stably and easily installed.

[0057] As shown in Figures 1-3 The air conditioner indoor unit 100 further includes a first air guide plate 171 and a second air guide plate 172. The first air guide plate 171 is rotatably arranged at the first air outlet 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 171 extends along the width direction or the height direction of the casing 1. The second air guide plate 172 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 172 extends along the width direction or the height direction of the casing 1.

[0058] When the air conditioner indoor unit 100 is in heating, the first air guide plate 171 located at the first air guide position extends obliquely downward or horizontally (is arranged), and the second air guide plate 172 located at the second air guide position extends obliquely downward or horizontally (is arranged). When the first air guide plate 171 (the second air guide plate 172) extends obliquely downward, the upper end of the first air guide plate 171 (the second air guide plate 172) is adjacent to the first side plate 11 (the second side plate 12) relative to the lower end of the first air guide plate 171 (the second air guide plate 172) in the length direction of the casing 1.

[0059] In other words, when the air conditioning indoor unit 100 performs heating, the first air deflector 171 in the first air deflection position has an angle greater than 0 degrees and less than or equal to 90 degrees with respect to the vertically downward direction. The second air deflector 172 in the second air deflection position has an angle greater than 0 degrees and less than or equal to 90 degrees with respect to the vertically downward direction. Thus, the first air deflector 171 and the second air deflector 172 can flow the hot air downward to form "carpet wind" when performing heating, so that the hot air more fully and more quickly covers the entire room, so as to further improve the heating effect.

[0060] When the air conditioning indoor unit 100 performs cooling, the first air deflector 171 in the first air deflection position extends obliquely upward or horizontally (is provided), and the second air deflector 172 in the second air deflection position extends obliquely upward or horizontally (is provided). 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 housing 1 relative to the lower end of the first air deflector 171 (the second air deflector 172).

[0061] In other words, when the air conditioning indoor unit 100 performs cooling, the first air deflector 171 in the first air deflection position has an angle greater than 0 degrees and less than or equal to 90 degrees with respect to the vertically upward direction. The second air deflector 172 in the second air deflection position has an angle greater than 0 degrees and less than or equal to 90 degrees with respect to the vertically upward direction. Thus, the user's comfort can be further improved.

[0062] As shown in Figure 1 and Figure 3 The air conditioning indoor unit 100 further includes a first support 41 and a first adjustment member 42, each of which is provided on the first side plate 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 housing 1, and the at least a portion of the first adjustment member 42 is connected to the first air deflector 171.

[0063] That is, the first adjustment member 42 can be movably provided in the length direction of the housing 1 as a whole. In addition, a portion of the first adjustment member 42 is movably provided in the length direction of the housing 1, so that the portion of the first adjustment member 42 is telescopically provided in the length direction of the housing 1 relative to another portion of the first adjustment member 42.

[0064] As shown in Figure 1 and Figure 3As shown, the air conditioner indoor unit 100 further includes a second support member 43 and a second adjustment member 44, each of which is provided to the second side plate 12. The second support member 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 casing 1, and the at least a portion of the second adjustment member 44 is connected to the second air deflector 172.

[0065] That is, the second adjustment member 44 can be movably provided in the length direction of the casing 1 as a whole. In addition, a portion of the second adjustment member 44 is movably provided in the length direction of the casing 1 so that the portion of the second adjustment member 44 is movably provided in the length direction of the casing 1 relative to another portion of the second adjustment member 44.

[0066] Accordingly, the inclination direction of the first air deflector 171 can be changed, and the angle of the first air deflector 171 with respect to 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 casing 1. Also, the inclination direction of the second air deflector 172 can be changed, and the angle of the second air deflector 172 with respect to 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 casing 1.

[0067] For example, when the air conditioner indoor unit 100 is not operated, the first air deflector 171 and the second air deflector 172 can be provided substantially vertically. When the air conditioner indoor unit 100 is operated for heating, the at least a portion of the first adjustment member 42 is moved in the length direction of the casing 1 toward the direction adjacent to the first side plate 11 (the second side plate 12) so that the first air deflector 171 is extended obliquely downward, and the at least a portion of the second adjustment member 44 is moved in the length direction of the casing 1 toward the direction adjacent to the second side plate 12 (the first side plate 11) so that the second air deflector 172 is extended obliquely downward.

[0068] When the air conditioner indoor unit 100 is operated for cooling, the at least a portion of the first adjustment member 42 is moved in the length direction of the casing 1 toward the direction away from the first side plate 11 (the second side plate 12) so that the first air deflector 171 is extended obliquely upward, and the at least a portion of the second adjustment member 44 is moved in the length direction of the casing 1 toward the direction away from the second side plate 12 (the first side plate 11) so that the second air deflector 172 is extended obliquely upward.

[0069] Optionally, the at least one part of the first adjusting member 42 is hinged with the first air deflector 171, and the first supporting 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 part of the second adjusting member 44 is hinged with the second air deflector 172, and the second supporting 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.

[0070] As shown in Figs. 1 and 2, 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 supporting members 41, which are arranged in the width direction of the casing 1. The first adjusting member 42 is located between the two first supporting members 41 in the width direction of the casing 1, and is located above the two first supporting members 41. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable. Figure 1 Figure 3 As shown in Figs. 1 and 2, 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 supporting members 41, which are arranged in the width direction of the casing 1. The first adjusting member 42 is located between the two first supporting members 41 in the width direction of the casing 1, and is located above the two first supporting members 41. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0071] Specifically, the at least one part of the first adjusting member 42 is hinged with the upper end of the first air deflector 171, and each first supporting 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.

[0072] As shown in Figs. 1 and 2, 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 supporting members 41, which are arranged in the width direction of the casing 1. The first adjusting member 42 is located between the two first supporting members 41 in the width direction of the casing 1, and is located above the two first supporting members 41. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable. Figure 1 Figure 3 As shown in Figs. 1 and 2, 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 supporting members 41, which are arranged in the width direction of the casing 1. The first adjusting member 42 is located between the two first supporting members 41 in the width direction of the casing 1, and is located above the two first supporting members 41. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0073] Specifically, the at least one part of the second adjusting member 44 is hinged with the upper end of the second air deflector 172, and each second supporting member 43 is hinged with 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.

[0074] 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 a third closed position and a 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.

[0075] ​​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.

[0076] As shown in Figure 2 and Figure 3 The heat exchanger 3 includes a front heat exchange portion 31 and a rear heat exchange portion 32. The front heat exchange portion 31 is arranged obliquely, and the upper end of the front heat exchange portion 31 is located in front of the lower end of the front heat exchange portion 31. The rear heat exchange portion 32 is arranged obliquely, and the upper end of the rear heat exchange portion 32 is located behind the lower end of the rear heat exchange portion 32. The air inlet side of each of the first fan 21, the second fan 22, and the third fan 23 is located between the upper end of the front heat exchange portion 31 and the upper end of the rear heat exchange portion 32 in the width direction (front-rear direction) of the cabinet 1.

[0077] The air entering the cabinet 1 through the air inlet 16 first passes through the front heat exchange portion 31 and / or the rear heat exchange portion 32 to exchange heat. The first fan 21, the second fan 22, and the third fan 23 inhale the heat-exchanged air and then deliver the heat-exchanged air into the room to cool or heat. By locating the air inlet side of each of the first fan 21, the second fan 22, and the third fan 23 between the upper end of the front heat exchange portion 31 and the upper end of the rear heat exchange portion 32 in the width direction of the cabinet 1, the first fan 21, the second fan 22, and the third fan 23 can effectively avoid inhaling air that has not been heat-exchanged, so as to further improve the cooling and heating effect of the air conditioner indoor unit 100.

[0078] Optionally, the lower end of the front heat exchange portion 31 is adjacent to the lower end of the rear heat exchange portion 32 in the width direction of the cabinet 1. Thus, air can be prevented from flowing between the lower end of the front heat exchange portion 31 and the lower end of the rear heat exchange portion 32 without being heat-exchanged, so as to avoid the first fan 21, the second fan 22, and the third fan 23 inhaling air that has not been heat-exchanged, thereby further improving the cooling and heating effect of the air conditioner indoor unit 100.

[0079] As shown in Figure 2As shown, the lower end of the front heat exchange part 31 and the lower end of the rear heat exchange part 32 are connected, and the heat exchanger 3 is generally V-shaped. Thus, air flow between the lower end of the front heat exchange part 31 and the lower end of the rear heat exchange part 32 can be further avoided without heat exchange, so that the first fan 21, the second fan 22 and the third fan 23 can further avoid sucking air without heat exchange, so as to further improve the cooling and heating effect of the air conditioner indoor unit 100. Moreover, by connecting the lower end of the front heat exchange part 31 and the lower end of the rear heat exchange part 32, the structure of the heat exchanger 3 can be more stable.

[0080] As shown, Figure 2 The air conditioner indoor unit 100 further comprises a water collecting tray 5, which is located directly below the lower end of the front heat exchange part 31 and the lower end of the rear heat exchange part 32, and the water collecting tray 5 is V-shaped or U-shaped. Thus, the water collecting tray 5 can be used to collect condensate water falling from the heat exchanger 3, so as to avoid the condensate water flowing out of the air conditioner indoor unit 100 and corroding the ceiling, wall and the like adjacent to the air conditioner indoor unit 100.
