[0021] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0022] An air conditioner indoor unit 100 according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in Figures 1-4 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, and a heat exchanger 3.

[0023] The casing 1 includes a first side plate 11 and a second side plate 12, the first side plate 11 and the second side plate 12 are oppositely arranged in a length direction of the casing 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. An air outlet side of the first fan 21 is matched with the first air outlet 111, and an air outlet side of the second fan 22 is matched with the second air outlet 121. The heat exchanger 3 is arranged in the casing 1.

[0024] The air conditioner indoor unit 100 according to an 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 a user, and make the user feel more comfortable.

[0025] Moreover, the air conditioner indoor unit 100 according to an embodiment of the present application can effectively increase air outlet area and air outlet direction by arranging multiple air outlets (the first air outlet 111 and the second air outlet 121), so as to make cold air and hot air blown by the air conditioner indoor unit 100 more fully and more quickly cover the whole room, and improve refrigeration and heating effects. Especially when the length of the casing 1 is small, the first air outlet 111 and the second air outlet 121 can effectively improve air outlet volume, so as to improve refrigeration and heating effects.

[0026] According to the air conditioner indoor unit 100 of the embodiment of the utility model, the first air fan 21 matched with the first air outlet 111 and the second air fan 22 matched with the second air outlet 121 are arranged, so that the air volume of the first air outlet 111 and the second air outlet 121 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 whole room, and the refrigeration and heating effect of the air conditioner indoor unit 100 is further improved.

[0027] Therefore, the air conditioner indoor unit 100 has the advantages of avoiding the cold air and the hot air directly blowing on the user, improving the comfort of the user, and good refrigeration and heating effect.

[0028] As shown in Figures 1-4 , the air conditioner indoor unit 100 comprises a shell 1, a first air fan 21, a second air fan 22 and a heat exchanger 3. The shell 1 comprises a first side plate 11, a second side plate 12, a bottom plate 141, a top plate 142 and a back plate 15.

[0029] 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 the first air outlet 111, and the second side plate 12 is provided with the second air outlet 121. The bottom plate 141 and the top plate 142 are oppositely arranged in the height direction of the shell 1. At least one of the bottom plate 141 and the back plate 15 is provided with the air inlet 16.

[0030] 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 .

[0031] As shown in Figure 4 , the back plate 15 comprises a back frame part 153, an upper plate part 151 and a lower plate part 152. The upper plate part 151 is arranged on the back frame part 153, and the lower plate part 152 is arranged on the back frame part 153. The lower plate part 152 is connected with the upper plate part 151, and the lower plate part 152 extends forward and downward from the upper plate part 151. That is, the lower plate part 152 is arranged obliquely, and the lower edge of the lower plate part 152 is located in front of the upper edge of the lower plate part 152. The lower plate part 152 is provided with the air inlet 16.

[0032] By extending the lower plate 152 forward and downward from the upper plate 151, the lower plate 152 is prevented from being pressed against walls or other parts, allowing air to enter the casing 1 through the air inlet 16 located on the lower plate 152. The air inlet 16 on the lower plate 152 further increases the air intake area, thereby increasing the air intake volume and, consequently, the air output volume. This allows the cool and hot air blown by the indoor unit 100 to more fully and quickly cover the entire room, improving cooling and heating efficiency.

[0033] Furthermore, by providing air inlets 16 on the base plate 141 and the lower plate 152, the direction of air intake can be increased, making it easier to form return air, thereby accelerating the circulation of air (airflow) in the room and improving the cooling and heating effect.

[0034] The rear frame portion 153 provides mounting space for the inclined lower plate portion 152. For example, the upper plate portion 151 may be adjacent to the rear edge of the rear frame portion 153 in the front-rear direction, and the lower edge of the lower plate portion 152 may be adjacent to the front edge of the rear frame portion 153 in the front-rear direction.

[0035] like Figures 1-3 As shown, the first air outlet 111 is located on the upper part of the first side plate 11, and the second air outlet 121 is located on the upper part of the second side plate 12. This facilitates the matching of the first air outlet 111 with the air outlet side of the first fan 21 and the second air outlet 121 with the air outlet side of the second fan 22, thereby facilitating the installation of the first fan 21 and the second fan 22 inside the housing 1.

[0036] 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. This can further increase the air outlet area of ​​the indoor unit 100, thereby increasing the air volume of the indoor unit 100, so as to further improve the cooling and heating effect of the indoor unit 100.

[0037] like Figures 1-3 As shown, the indoor unit 100 of the air conditioner further includes a first air guide plate 131 and a second air guide plate 132. The first air guide plate 131 is rotatably disposed at the first air outlet 111 of the first side plate 11 between a first closed position and a first air guiding position, and the rotation axis of the first air guide plate 131 extends along the width or height direction of the casing 1. The second air guide plate 132 is rotatably disposed at the second air outlet 121 of the second side plate 12 between a second closed position and a second air guiding position, and the rotation axis of the second air guide plate 132 extends along the width or height direction of the casing 1.

[0038] When the indoor unit 100 of the air conditioner is in heating mode, the first air guide plate 131 located at the first air guide position extends downward at an angle or horizontally (set), and the second air guide plate 132 located at the second air guide position extends downward at an angle or horizontally (set). When the first air guide plate 131 (second air guide plate 132) extends downward at an angle, the upper end of the first air guide plate 131 (second air guide plate 132) is adjacent to the lower end of the first side plate 11 (second side plate 12) in the length direction of the housing 1 relative to the lower end of the first air guide plate 131 (second air guide plate 132).

[0039] In other words, when the indoor unit 100 of the air conditioner is in heating mode, the angle between the first air guide plate 131 located at the first air guide position and the vertical downward direction is greater than 0 degrees and less than or equal to 90 degrees. The angle between the second air guide plate 132 located at the second air guide position and the vertical downward direction is greater than 0 degrees and less than or equal to 90 degrees. Therefore, during heating, the first air guide plate 131 and the second air guide plate 132 can cause hot air to flow downwards to form a "carpet wind," thereby allowing the hot air to more fully and quickly cover the entire room, further improving the heating effect.

[0040] When the indoor unit 100 of the air conditioner is cooling, the first air guide plate 131 located at the first air guide position extends obliquely upward or horizontally (set), and the second air guide plate 132 located at the second air guide position extends obliquely upward or horizontally (set). When the first air guide plate 131 (second air guide plate 132) extends obliquely upward, the upper end of the first air guide plate 131 (second air guide plate 132) is away from the lower end of the first side plate 11 (second side plate 12) in the length direction of the housing 1.

[0041] In other words, when the indoor unit 100 of the air conditioner is cooling, the angle between the first air guide plate 131 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 132 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.

[0042] like Figures 1-3 As shown, the indoor unit 100 of the air conditioner further includes a first support member 41 and a first adjusting member 42, each of which is disposed on the first side plate 11. The first support member 41 is connected to the first air guide plate 131. At least a portion of the first adjusting member 42 is movably disposed along the length direction of the housing 1, and this at least portion of the first adjusting member 42 is connected to the first air guide plate 131.

[0043] That is, the first adjustment member 42 can be movably provided in its entirety in the length direction of the cabinet 1. In addition, a portion of the first adjustment member 42 can be 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 relative to another portion of the first adjustment member 42.

[0044] As shown in FIG. 1, the air conditioning indoor unit 100 further includes a first adjustment member 42 and a second adjustment member 44. The first adjustment member 42 is provided on the first side plate 11, and the second adjustment member 44 is provided on the second side plate 12. Figures 1-3 The first adjustment member 42 is connected to the first air deflector 131. At least a portion of the second adjustment member 44 is movably provided in the length direction of the cabinet 1, and the portion of the second adjustment member 44 is connected to the second air deflector 132.

[0045] That is, the second adjustment member 44 can be movably provided in its entirety in the length direction of the cabinet 1. In addition, a portion of the second adjustment member 44 can be 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 relative to another portion of the second adjustment member 44.

[0046] Thus, by moving the at least a portion of the first adjustment member 42 in the length direction of the cabinet 1, the inclination direction of the first air deflector 131 can be changed, and the included angle between the first air deflector 131 and the vertically downward direction or the vertically upward direction can be changed. Also, by moving the at least a portion of the second adjustment member 44 in the length direction of the cabinet 1, the inclination direction of the second air deflector 132 can be changed, and the included angle between the second air deflector 132 and the vertically downward direction or the vertically upward direction can be changed.

[0047] For example, when the air conditioning indoor unit 100 is not operated, the first air deflector 131 and the second air deflector 132 can be provided substantially vertically. When the air conditioning 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 cabinet 1 toward the direction adjacent to the first side plate 11 (the second side plate 12) so that the first air deflector 131 is extended obliquely downward, and the at least a portion of the second adjustment member 44 is moved in the length direction of the cabinet 1 toward the direction adjacent to the second side plate 12 (the first side plate 11) so that the second air deflector 132 is extended obliquely downward.

[0048] When the air conditioning 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 cabinet 1 toward the direction away from the first side plate 11 (the second side plate 12) so that the first air deflector 131 is extended obliquely upward, and the at least a portion of the second adjustment member 44 is moved in the length direction of the cabinet 1 toward the direction away from the second side plate 12 (the first side plate 11) so that the second air deflector 132 is extended obliquely upward.

[0049] Optionally, the at least one part of the first adjusting member 42 is hinged with the first air deflector 131, and the first supporting member 41 is hinged with the first air deflector 131. 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 132, and the second supporting member 43 is hinged with the second air deflector 132. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0050] As shown in Figure 2 , the rotation axis of the first air deflector 131 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 the first adjusting member 42 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.

[0051] Specifically, the at least one part of the first adjusting member 42 is hinged with the upper end of the first air deflector 131, and each first supporting member 41 is hinged with the lower end of the first air deflector 131. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0052] As shown in Figure 2 , the rotation axis of the second air deflector 132 extends along the width direction of the casing 1. The air conditioner indoor unit 100 comprises two second supporting members 43, which are arranged in the width direction of the casing 1. The second adjusting member 44 is located between the two second supporting members 43 in the width direction of the casing 1, and the second adjusting member 44 is located above the two second supporting members 43. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0053] Specifically, the at least one part of the second adjusting member 44 is hinged with the upper end of the second air deflector 132, and each second supporting member 43 is hinged with the lower end of the second air deflector 132. In this way, the structure of the casing 1 and the air conditioner indoor unit 100 can be more reasonable.

[0054] The air outlet side of the first fan 21 cooperates with the first air outlet 111, and the air outlet side of the second fan 22 cooperates with the second air outlet 121. Optionally, the first fan 21 is a centrifugal fan or a cross-flow fan, and the second fan 22 is a centrifugal fan or a cross-flow fan. In this way, the first fan 21 and the second fan 22 can effectively overcome the resistance of the heat exchanger 3 to achieve long-distance air supply, so that the cold air and hot air blown out by the air conditioner indoor unit 100 can more fully and quickly cover the entire room, further improving the refrigeration and heating effect of the air conditioner indoor unit 100.

[0055] As shown in Figure 3As shown, the heat exchanger 3 comprises a first side heat exchange portion 31, a second side heat exchange portion 32 and a lower heat exchange portion 33. The first side heat exchange portion 31 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 32 is located between the air outlet side of the second fan 22 and the second air outlet 121. The lower heat exchange portion 33 is located between the air inlet 16 of the casing 1 and the air inlet side of each of the first fan 21 and the second fan 22 in the height direction of the casing 1.

[0056] That is, the lower heat exchange portion 33 is located between the air inlet 16 of the casing 1 and the air inlet side of the first fan 21 in the height direction of the casing 1, and the lower heat exchange portion 33 is located between the air inlet 16 of the casing 1 and the air inlet side of the second fan 22 in the height direction of the casing 1.

[0057] The air entering the casing 1 from the air inlet 16 first flows through the lower heat exchange portion 33 and exchanges heat with the lower heat exchange portion 33. Part of the air after heat exchange is sucked by the first fan 21, and then the part of the air is output by the first fan 21 and exchanges heat with the first side heat exchange portion 31 to achieve secondary heat exchange. Another part of the air after heat exchange is sucked by the second fan 22, and then the part of the air is output by the second fan 22 and exchanges heat with the second side heat exchange portion 32 to achieve secondary heat exchange. Thus, the heat exchange efficiency of the heat exchanger 3 can be further improved, and thus the cooling and heating effect of the air conditioner indoor unit 100 is further improved.

[0058] As shown in FIG. 1, the lower heat exchange portion 33 is located between the air inlet 16 of the casing 1 and the air inlet side of the first fan 21 in the height direction of the casing 1, and the lower heat exchange portion 33 is located between the air inlet 16 of the casing 1 and the air inlet side of the second fan 22 in the height direction of the casing 1. Figure 3 As shown, the lower heat exchange portion 33 is horizontally or obliquely arranged. The lower heat exchange portion 33 has a first end portion 331 and a second end portion 332 opposite in the length direction of the casing 1. Each of the first side heat exchange portion 31 and the second side heat exchange portion 32 is vertically or obliquely arranged. The lower end portion 311 of the first side heat exchange portion 31 is in contact with the first end portion 331 of the lower heat exchange portion 33, and the lower end portion 321 of the second side heat exchange portion 32 is in contact with the second end portion 332 of the lower heat exchange portion 33.

[0059] Thus, the air can be prevented from flowing between the first side heat exchange portion 31 and the lower heat exchange portion 33 and between the second side heat exchange portion 32 and the lower heat exchange portion 33, so that the air output by the first fan 21 is prevented from not exchanging heat with the first side heat exchange portion 31, and the air output by the second fan 22 is prevented from not exchanging heat with the second side heat exchange portion 32, so as to further ensure that the air conditioner indoor unit 100 has excellent cooling and heating effect.

[0060] Alternatively, the lower end portion 311 of the first side heat exchange portion 31 and the first end portion 331 of the lower heat exchange portion 33 are connected, and the lower end portion 321 of the second side heat exchange portion 32 and the second end portion 332 of the lower heat exchange portion 33 are connected. Thus, the structure of the heat exchanger 3 can be more stable, and the heat exchanger 3 can be more easily assembled.

[0061] like Figure 3 As shown, the lower heat exchange section 33 is located above the air inlet 16 and below the first fan 21 and the second fan 22. The first side plate 11, the first side heat exchange section 31, the first fan 21, the second fan 22, the second side heat exchange section 32, and the second side plate 12 are arranged sequentially along the length of the casing 1.

[0062] like Figure 3 As shown, the thickness direction of each of the first side heat exchange section 31 and the second side heat exchange section 32 is aligned with the length direction of the casing 1. This allows the first side heat exchange section 31 and the second side heat exchange section 32 to have a larger heat exchange area, thereby improving the heat exchange efficiency of the heat exchanger 3.

[0063] like Figure 3 As shown, the indoor unit 100 of the air conditioner also includes a water tray 5, which is located directly below the heat exchanger 3 to receive condensate water falling from the heat exchanger 3.

[0064] like Figure 3 As shown, both the first fan 21 and the second fan 22 are centrifugal fans, and the air inlet 211 of the first fan 21 and the air inlet 221 of the second fan 22 are both open downwards. This allows the air inlet 211 of the first fan 21 and the air inlet 221 of the second fan 22 to better match the air inlet 16 of the base plate 141 and / or the lower plate 152.

[0065] The air outlet 212 of the first fan 21 opens towards the first air outlet 111 along the length of the casing 1, and the air outlet 222 of the second fan 22 opens towards the second air outlet 121 along the length of the casing 1. That is, the air outlets 212 of the first fan 21 and 222 of the second fan 22 open in opposite directions, i.e., they are arranged back-to-back. This allows the air outlet 212 of the first fan 21 to better match the first air outlet 111, and the air outlet 222 of the second fan 22 to better match the second air outlet 121.

[0066] For example, the air inlet 211 of the first fan 21, the air inlet 16 of the lower heat exchange section 33 and the base plate 141 are directly opposite each other in the vertical direction (height direction of the casing 1), and the air inlet 221 of the second fan 22, the air inlet 16 of the lower heat exchange section 33 and the base plate 141 are directly opposite each other in the vertical direction (height direction of the casing 1). The air outlet 212 of the first fan 21 opens to the left, and the air outlet 212 and the first air outlet 111 of the first fan 21 are directly opposite each other in the length direction of the casing 1. The air outlet 222 of the second fan 22 opens to the right, and the air outlet 222 and the second air outlet 121 of the second fan 22 are directly opposite each other in the length direction of the casing 1.

The first fan 21 comprises a first motor 213, a first shaft 214 and a first centrifugal fan wheel 215, and the first motor 213 is arranged on the top plate 142 of the casing 1. The first shaft 214 is connected with each of the first motor 213 and the first centrifugal fan wheel 215, that is, the first motor 213 is connected with the first centrifugal fan wheel 215 through the first shaft 214.

[0068] The second fan 22 comprises a second motor 223, a second shaft 224 and a second centrifugal fan wheel 225, and the second motor 223 is arranged on the top plate 142 of the casing 1. The second shaft 224 is connected with each of the second motor 223 and the second centrifugal fan wheel 225, that is, the second motor 223 is connected with the second centrifugal fan wheel 225 through the second shaft 224. Thus, the structure of the air conditioner indoor unit 100 can be more reasonable.

[0069] Optionally, as shown in the drawings, the top plate 142 of the casing 1 is provided with a first mounting seat 61 and a second mounting seat 62. The first motor 213 is arranged on the first mounting seat 61, and the second motor 223 is arranged on the second mounting seat 62. Thus, the first motor 213 and the second motor 223 can be more stably and easily mounted on the top plate 142, so that the first fan 21 and the second fan 22 can be more stably and easily mounted. Figure 3

[0070] As shown in the drawings, the first shaft 214 and the second shaft 224 both extend along the up-down direction (the height direction of the casing 1), the first centrifugal fan wheel 215 is arranged in the first volute 216 of the first fan 21, and the second centrifugal fan wheel 225 is arranged in the second volute 226 of the second fan 22. ​ In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
