The first plane 312 and the second plane 322 allow the airflow to be blown out along the plane, reducing the loss of the airflow, thereby increasing the amount of air blown out and improving the user experience. The first curved surface 311 and the second curved surface 321 guide the airflow to both sides of the air conditioner indoor unit 100, increase the air outlet angle of the air conditioner indoor unit 100, and further improve the user experience.

[0050] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the air conditioner indoor unit 100 further includes a cross-flow fan 40, which is vertically arranged in the housing 10 to blow air into the room.

[0051] In some embodiments of the present invention, Figure 3 As shown, the angle between the first plane 312 and the second plane 322 is 8° to 10°. Preferably, the angle between the first plane 312 and the second plane 322 is 9°.

[0052] In some embodiments of the present invention, Figure 1 As shown, the air conditioner indoor unit 100 further includes an air supply duct 50, which is connected to the air outlet 20 and is disposed in the housing 10. The air supply duct 50 has a first wall 510 and a second wall 520 that are disposed opposite to each other, the first wall 510 is disposed vertically, and the two second walls 520 are located between the two first walls 510. The first wall 510 includes a first section 511, which is located at the front end of the first wall 510, and the first section 511 extends laterally to cooperate with the first curved surface 311 to guide air laterally when supplying air at a wide angle.

[0053] In the present embodiment, the air supply duct 50 has a first wall surface 510 and a second wall surface 520, and the first wall surface 510 is a wall surface of the air supply duct 50 close to the side of the housing 10. The first section 511 extends to the side, that is, the front end of the first wall surface 510 extends to the side. When the air guide plate 30 closes the air outlet 20, the end of the air guide plate 30 close to the first curved surface 311 is connected or in contact with the first section 511. When the air guide plate 30 opens the air outlet 20, the first section 511 and the first curved surface 311 extend to the side of the air conditioner indoor unit 100, forming an air supply channel for supplying air to the side, increasing the air outlet angle of the air conditioner indoor unit 100, and improving the user experience.

[0054] In some embodiments of the present invention, Figure 1 As shown, the first wall surface 510 further includes a second section 512 , and a rounded corner is provided at the connection between the first section 511 and the second section 512 .

[0055] In this embodiment, the connection between the first section 511 and the second section 512 is rounded, that is, the corner where the first wall 510 extends to the side is rounded. When the airflow is blown out along the first wall 510, the flow channel of the airflow is smoother, reducing the loss during the flow of the airflow, avoiding the reduction of the air volume, and thus improving the user experience.

[0056] In some embodiments of the present invention, Figure 1 As shown, in the direction from back to front, the second section 512 is inclined toward the side and front, the second wall 520 extends toward the side and front, and the distance between the first wall 510 and the second wall 520 gradually increases.

[0057] In this embodiment, from the back to the front, the first wall 510 and the second wall 520 extend to the side and front, so that the air supply duct 50 extends to the side and front. In addition, along the air supply trajectory of the air supply duct 50, the distance between the first wall 510 and the second wall 520 gradually increases. The distance between the first wall 510 and the second wall 520 at the air outlet 20 is the largest, so that the airflow through the air outlet 20 is increased, the air output of the air conditioner indoor unit 100 is increased, and the user experience is improved.

[0058] In some embodiments of the present invention, Figure 4 As shown, the air guide plate 30 has a first position. When the air guide plate 30 is at the first position, the air conditioner indoor unit 100 has a maximum air outlet angle.

[0059] In this embodiment, when the air guide plate 30 is in the first position, the first curved surface 311 is in front of the first plane 312, and the section of the first curved surface 311 at one end away from the first plane 312 extends in the left-right direction. At this time, the air supply channel between the first section 511 and the first curved surface 311 is directed to the left and right sides of the air conditioner indoor unit 100, thereby realizing wide-angle air supply to the air conditioner indoor unit 100, meeting the blowing needs of users on both sides of the air conditioner indoor unit 100, and thus improving the user experience. Figure 5 As shown, after simulation analysis, when the air guide plate 30 is in the first position, the air outlet angle of the air conditioner indoor unit 100 can reach 180°

[0060] In some embodiments of the present invention, Figure 6 As shown, the air guide plate 30 has a second position. When the air guide plate 30 is at the second position, the air conditioner indoor unit 100 has a maximum air supply volume.

[0061] In this embodiment, when the air guide plate 30 is at the second position, the first plane 312 and the second section 512 extend in the same direction, or the second plane 322 and the second wall surface 520 extend in the same direction. When the airflow in the air supply duct 50 passes through the air guide plate 30, the airflow still maintains the original air supply direction, and the loss of the airflow in the air supply duct 50 is minimized, so that the airflow blown out from the air outlet maintains the maximum air volume, thereby improving the user experience.

[0062] In some embodiments of the present invention, Figure 7 As shown, the air guide plate 30 has a third position. When the air guide plate 30 is at the third position, the air conditioner indoor unit 100 supplies air to the front side.

[0063] In this embodiment, when the air guide plate 30 is at the third position, the first plane 312 and the second plane 322 extend in the vertical direction, and the end of the air guide plate 30 away from the first curved surface 311 contacts the second section 512. When the air guide plate 30 guides air, the airflow flows along the second section 512, and then blows out toward the front side of the air conditioner indoor unit 100 along the second air guide surface 320, so that the air is discharged from the front side of the air conditioner indoor unit 100.

[0064] In some embodiments of the present invention, each air deflector 30 is controlled individually so that the two air deflectors 30 have different rotation angles.

[0065] In this embodiment, the two air guide plates 30 are equipped with independent motors so that the two air guide plates 30 can rotate independently. By controlling each air guide plate 30 individually, the two air guide plates 30 have different air supply positions, thereby forming a variety of unique air supply modes, thereby improving the user experience.

[0066] In some embodiments of the present invention, Figure 2 As shown, the air guide plate 30 is vertically arranged at the air outlet 20.

[0068] In this embodiment, the rotation axis 80 of the air guide plate 30 is located on the air guide plate 30. When the air guide plate 30 is installed or rotated, the occupied area of ​​the air guide plate 30 is reduced, saving space in the air conditioner indoor unit 100, thereby reducing the production cost of the air conditioner indoor unit 100 and improving the user experience.

[0069] In some embodiments of the present invention, Figure 1 As shown, the first section 511 is located at the rear side of the front end of the second wall 520 .

[0070] In this embodiment, if Figure 2 As shown, the air outlet 20 is located at the front and side corners of the housing 10. The airflow blown out from the air outlet 20 can be blown into the room from the front or side of the air conditioner, increasing the air supply angle of the air outlet 20, thereby improving the user experience of the customer.

The area of ​​the air inlet 60 is relatively large, which increases the air intake of the air conditioner indoor unit 100, thereby increasing the air outlet of the air conditioner indoor unit 100 and improving the user experience.

[0073] In some embodiments of the present invention, Figure 1 As shown, the air conditioner indoor unit 100 further includes a heat exchanger 70, which is disposed at the air inlet 60 to perform heat exchange on the air flow entering the air inlet 60.
