Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0032] The indoor unit of the air conditioner according to the present embodiments will be described below with reference to the accompanying drawings.

[0033] As shown in Figures 1-5 The indoor unit of the air conditioner according to the present embodiments will be described below with reference to the accompanying drawings.

[0034] The air outlet air duct 400 is downstream of the first cross-flow fan 300, and when the first cross-flow fan 300 rotates around its rotation axis, it can cause the airflow to enter the air outlet air duct 400 and make the airflow flow through the upstream and downstream of the air outlet air duct 400 in turn, and finally blow into the indoor area.

[0035] The flow dividing member 500 is arranged in the air outlet air duct 400, and the flow dividing member 500 includes a first air guide surface 511 and a second air guide surface 521. The first air guide surface 511 and the air outlet air duct 400 form a first air duct 410 therebetween, and the second air guide surface 521 and the air outlet air duct 400 form a second air duct 420 therebetween. That is, with the windward end of the flow dividing member 500 as a dividing point, the first air duct 410 has an inlet end and the second air duct 420 has an inlet end. When the airflow in the air outlet air duct 400 flows through the flow dividing member 500, the airflow will be divided into two airflows by the flow dividing member 500, and enter the first air duct 410 and the second air duct 420 from the inlet end of the first air duct 410 and the inlet end of the second air duct 420 respectively, so that the indoor unit of the air conditioner according to the present embodiments realizes double air duct air supply.

[0036] The decorative piece 600 is arranged at the outlet of the outlet air duct 400, and is located at the downstream side of the flow dividing piece 500. The back side of the decorative piece 600 forms an appearance surface and contacts the air in the room. The decorative piece 600 has a first end portion 610 and a second end portion 620. The first end portion 610 is a portion of the decorative piece 600 close to the first air duct 410, and a first outlet is formed between the first end portion 610 and the wall surface of the outlet air duct 400. The air flow blown out by the first air duct 410 is blown into the room through the first outlet. The second end portion 620 is a portion of the decorative piece 600 close to the second air duct 420, and a second outlet is formed between the second end portion 620 and the wall surface of the outlet air duct 400. The air flow blown out by the second air duct 420 is blown into the room through the second outlet.

[0037] The flow dividing piece 500 is configured such that the first air flow guide surface 511 of the flow dividing piece 500 causes the air flow blown out by the first air duct 410 to be spaced apart from the first end portion 610, and the second air flow guide surface 521 of the flow dividing piece 500 causes the air flow blown out by the second air duct 420 to be spaced apart from the second end portion 620.

[0038] That is, the first air flow guide surface 511 restricts the air flow in the first air duct 410, so that the air flow blown out from the first outlet is spaced apart from the first end portion 610 of the decorative piece 600 by a certain distance, i.e., the air flow blown out from the first outlet does not contact the first end portion 610. Since the first end portion 610 of the decorative piece 600 contacts the hot air in the room, the temperature of the first end portion 610 is high. The cold air flow blown out from the first air duct 410 does not contact the first end portion 610, so that the first end portion 610 does not condense condensate. The second air flow guide surface 521 restricts the air flow in the second air duct 420, so that the air flow blown out from the second outlet is spaced apart from the second end portion 620 of the decorative piece 600 by a certain distance, i.e., the air flow blown out from the second outlet does not contact the second end portion 620. Since the second end portion 620 of the decorative piece 600 contacts the hot air in the room, the temperature of the second end portion 620 is high. The cold air flow blown out from the second air duct 420 does not contact the second end portion 620, so that the second end portion 620 does not condense condensate.

[0039] Compared with the related art, the air conditioner indoor unit of the embodiment of the utility model sets the shunt piece 500 on the upstream of the decoration piece 600, makes the shunt piece 500 carry out wind flow and guide to the airflow in the air outlet air duct 400, makes the air conditioner indoor unit of the embodiment of the utility model realize two outlet air outlet. And, the first air guide surface 511 and the second air guide surface 521 of the shunt piece 500 can respectively restrict the air outlet of the first air duct 410 and the second air duct 420 in advance, make the air outlet of the first air duct 410 and the first end 610 of the decoration piece 600 are spaced apart, and make the air outlet of the second air duct 420 and the second end 620 of the decoration piece 600 are spaced apart, avoid the cold air blown by the first air duct 410 and the second air duct 420 and the first end 610 and the second end 620 contact and produce condensate, therefore solve the problem that the condensate is easily condensed on the decoration piece 600, improve the use experience of user.

[0040] As Figures 1-5 Indicated, the air conditioner indoor unit of the embodiment of the utility model includes the shell 100, the heat exchanger 200, the first cross-flow fan 300, the air outlet air duct 400, the shunt piece 500 and the decoration piece 600.

[0041] The heat exchanger 200, the air outlet air duct 400, the first cross-flow fan 300, the shunt piece 500 and the decoration piece 600 are all arranged in the shell 100. The shell 100 is equipped with the air inlet 110 and the air outlet 120, the outlet of the air outlet air duct 400 is connected with the air outlet 120, the first cross-flow fan 300 is arranged at the upstream inlet formed in the air outlet air duct 400. The heat exchanger 200 is arranged between the air inlet 110 and the first cross-flow fan 300.

[0042] When the air conditioner indoor unit of the embodiment runs, the first cross-flow fan 300 rotates and promotes the airflow in the room to enter the shell 100 from the air inlet 110 and exchanges heat with the heat exchanger 200. After heat exchange, the airflow enters the air outlet air duct 400, passes through the first air duct 410 and the second air duct 420 after passing through the shunt piece 500, and is blown into the room from the air outlet 120 through the first outlet and the second outlet respectively, realizing wide-angle air supply.

[0043] In some embodiments, as Figure 3 Indicated, on the cross section perpendicular to the rotation axis of the first cross-flow fan 300, the first end 610 and the second end 620 are located between the first extension line 512 that the first air guide surface 511 extends towards the downstream and the second extension line 522 that the second air guide surface 521 extends towards the downstream, and the first end 610 is spaced apart from the first extension line 512, and the second end 620 is spaced apart from the second extension line 522.

[0044] The guiding structure directs the airflow, ensuring that even after the airflow detaches from the guiding structure, it continues to flow a certain distance in the direction guided by the structure. In other words, after the airflow exits the first air duct 410, it continues to flow a certain distance along the first extension line 512 of the first air guide surface 511, moving away from the second air duct 420. This ensures that the airflow exiting the first air duct 410 does not contact the first end 610 of the decorative element 600. Similarly, after the airflow exits the second air duct 420, it continues to flow a certain distance along the second extension line 522 of the second air guide surface 521, moving away from the first air duct 410. This ensures that the airflow exiting the second air duct 420 does not contact the second end 620 of the decorative element 600.

[0045] Optionally, the first air guide surface 511 is planar; and / or, the second air guide surface 521 is planar. That is, the first air guide surface 511 is planar; or, the second air guide surface 521 is planar; or, both the first air guide surface 511 and the second air guide surface 521 are planar. Having planar first air guide surfaces 511 and 521 can reduce energy loss during airflow, reduce wind loss, and increase the airflow output of the first air duct 410 and the second air duct 420.

[0046] In some embodiments, such as Figures 1-3 As shown, the flow divider 500 includes a first guide section 510 and a second guide section 520 disposed opposite to each other in the width direction of the air outlet duct 400. The first guide section 510 is inclined, and its upstream end is closer to the second guide section 520 than its downstream end, with the windward surface of the first guide section 510 forming a first guide surface 511. The second guide section 520 is inclined, and its upstream end is closer to the first guide section 510 than its downstream end, with the windward surface of the second guide section 520 forming a second guide surface 521.

[0047] The first air guide section 510 and the second air guide section 520 are both inclined, so that the first air guide section 510 and the second air guide section 520 form a first air duct 410 and the second air duct 420 with a certain angle between them and the air outlet duct 400, so that the indoor unit of the air conditioner in this embodiment can achieve wide-angle air supply.

[0048] And the downstream of the first air guide section 510 is away from the second air guide section 520 relative to its upstream, so that the first air guide section 510 can guide the air outlet of the first air duct 410 to blow away from the side of the second air guide section 520, thereby ensuring that the air outlet of the first air duct 410 does not contact the first end portion 610, preventing the condensation of condensed water on the first end portion 610. The downstream of the second air guide section 520 is away from the first air guide section 510 relative to its upstream, so that the second air guide section 520 can guide the air outlet of the second air duct 420 to blow away from the side of the first air guide section 510, thereby ensuring that the air outlet of the second air duct 420 does not contact the second end portion 620, preventing the condensation of condensed water on the second end portion 620

[0049] In some embodiments, as shown in Figures 1-3 The shunt 500 further includes an arc-shaped end 530 facing the upstream of the air outlet duct 400, and the arc-shaped end 530 is smoothly connected to the upstream end of the first air guide section 510 and the upstream end of the second air guide section 520 at both ends of the air outlet duct 400. When the airflow of the air outlet duct 400 hits the arc-shaped end 530, the energy loss of the airflow is reduced, and the wind loss is reduced.

[0050] In some embodiments, the included angle between the first air guide surface 511 and the second air guide surface 521 is 40°-60°. Alternatively, the included angle between the first air guide surface 511 and the second air guide surface 521 is 40°-60°. Alternatively, the included angle between the first air guide surface 511 and the second air guide surface 521 is 45°-50°. Alternatively, the included angle between the first air guide surface 511 and the second air guide surface 521 is 47°-52°. On the one hand, a certain included angle is formed between the first air duct 410 and the second air duct 420, thereby expanding the air supply range of the air conditioner indoor unit; on the other hand, the included angle between the first air guide surface 511 and the second air guide surface 521 is prevented from being too large, preventing the shunt 500 from generating too much resistance to the airflow, thereby making the first air duct 410 140 and the second air duct 420 150.

[0051] Wherein, the included angle between the first windward surface 211 and the second windward surface 212 includes but is not limited to 40°, 47°, 50°, 53°, 55°, 56°, 58°, 59° or 60°.

[0052] In some embodiments, as shown in Figure 4 and Figure 5 The decorative piece 600 includes a first surface 630 facing the air outlet duct 400 and a second surface 640 facing away from the air outlet duct 400, and the second surface 640 is connected to the first end portion 610 and the second end portion 620 at both ends of the air outlet duct 400 in the width direction.

[0053] The decorative piece 600 is provided with an air outlet passage 650 having a first opening 651 and a second opening 652. The first opening 651 is formed on the first surface 630 to enable the air outlet passage 650 to communicate with the air outlet duct 400. The second opening 652 is formed on the second surface 640, and the second opening 652 is provided with the second cross-flow fan 540 configured to facilitate the formation of an air flow entering the air outlet passage 650 from the first opening 651, blowing out of the second opening 652, and flowing towards one of the first end portion 610 or the second end portion 620.

[0054] When the air conditioner indoor unit of the present embodiment is in operation, when the air flow in the air outlet duct 400 flows through the first opening 651, part of the air flow will be sucked into the air outlet passage 650 due to the negative pressure formed in the air outlet passage 650 by the second cross-flow fan 540, and the rotation of the second cross-flow fan 540 will facilitate the blowing of the part of the air flow in the air outlet passage 650 towards one of the first end portion 610 or the second end portion 620, so that the one of the first end portion 610 or the second end portion 620, which is originally in contact with the indoor hot air, is isolated from the indoor hot air by the blowing of the cold air flow in the air outlet passage 650, thereby avoiding the condensation of condensate on the one of the first end portion 610 or the second end portion 620.

[0055] The direction of the air flow flowing out of the second opening 652 is related to the rotation direction of the second cross-flow fan 540. For example Figure 4 As shown in the figure, when the second cross-flow fan 540 rotates clockwise, the air flow blown out of the second opening 652 is directed towards the first end portion 610; when the second cross-flow fan 540 rotates counterclockwise, the air flow blown out of the second opening 652 is directed towards the second end portion 620.

[0056] In some embodiments, as Figure 4 shown, the second cross-flow fan 540 is arranged in the air outlet passage 650, which can visually shield the second cross-flow fan 540, so that the appearance of the air conditioner indoor unit of the present embodiment is more beautiful, thereby improving the user experience.

[0057] In some embodiments, as Figure 6 shown, the air conditioner indoor unit of the present embodiment further includes a first air deflector 710 and a second air deflector 720. The first air deflector 710 is rotatably connected in the first air duct 410, and the rotation axis of the first air deflector 710 is parallel to the rotation axis of the first cross-flow fan 300. The second air deflector 720 is rotatably connected in the second air duct 420, and the rotation axis of the first air deflector 710 is parallel to the rotation axis of the first cross-flow fan 300.

[0058] That is, the first air duct 410 is provided with a rotatable first air deflector 710, by swinging the first air deflector 710, the inclination direction of the air deflector is changed, the air outlet direction of the first air duct 410 is adjusted. The first air duct 410 is provided with a rotatable second air deflector 720, by swinging the second air deflector 720, the inclination direction of the air deflector is changed, the air outlet direction of the second air duct 420 is adjusted.

The air conditioner of the embodiment of the utility model has the indoor unit, the shunt member 500 is arranged at the upstream of the decoration piece 600, the shunt member 500 guides the airflow in the air outlet air duct 400, the air conditioner indoor unit of the embodiment can realize two outlet air outlet. In addition, the first air deflector surface 511 and the second air deflector surface 521 of the shunt member 500 can respectively restrict the air outlet of the first air duct 410 and the second air duct 420 in advance, the air outlet of the first air duct 410 is spaced apart from the first end portion 610 of the decoration piece 600, and the air outlet of the second air duct 420 is spaced apart from the second end portion 620 of the decoration piece 600, so that the cold air blown by the first air duct 410 and the second air duct 420 is prevented from contacting the first end portion 610 and the second end portion 620 to generate condensed water, and therefore the problem that the condensed water is easily condensed on the decoration piece 600 is solved, and the use experience of the user is improved.
