[0035] Specifically, the front end of the first partition 4 is connected with the front inner side wall 11 of the mounting shell 1, the rear end of the second partition 5 is connected with the rear inner side wall 12 of the mounting shell 1, and the rear end of the first partition 4 and the front end of the second partition 5 abut each other, so that the air outlet 23 of the centrifugal volute assembly 2 can be divided into the first outlet 94 and the second outlet 95.

[0041] In some embodiments of the present application, the first partition 4 is formed as an upwardly protruding plate, and the second partition 5 is formed as an upwardly protruding plate, which can increase the setting area of the first partition 4 and the second partition 5, and when the airflow moves upward, the contact area of the airflow with the first partition 4 and the second partition 5 can be increased, and under the action of the same force, the first partition 4 and the second partition 5 can be prevented from separating from the mounting shell 1, thereby ensuring the working performance of the air conditioner indoor unit 10.

[0042] In some embodiments of the present application, as shown in the figure, Figure 4 As shown in the figure, the opposite ends of the first partition 4 and / or the second partition 5 can be provided with horizontally extending flanges 7, for example, the opposite end of the second partition 5 is provided with a horizontally extending flange 7 relative to the first partition 4, and such arrangement can improve the structural strength of the second partition 5, and can also stably assemble the second partition 5 with the mounting shell 1 and the vertical partition 6.

This arrangement can make the part of the left arc surface 8 corresponding to the air supply cylinder 3 have similar structure, and can make the part of the right arc surface 9 corresponding to the air supply cylinder 3 have similar structure. When the airflow flows through the area between the left arc surface 8 and the air supply cylinder 3 and the area between the right arc surface 9 and the air supply cylinder 3, the airflow can flow through the area between the left arc surface 8 and the air supply cylinder 3 and the area between the right arc surface 9 and the air supply cylinder 3 more easily, thereby reducing the air resistance in the air conditioner indoor unit 10.

[0044] In some embodiments of the present application, as shown in the figure, Figure 3 As shown in the figure, the left arc surface 8 and the right arc surface 9 are arranged symmetrically with respect to the air supply cylinder 3.

When the airflow flows through the area between the left arc surface 8 and the air supply cylinder 3 and the area between the right arc surface 9 and the air supply cylinder 3, the airflow can flow through the area between the left arc surface 8 and the air supply cylinder 3 and the area between the right arc surface 9 and the air supply cylinder 3 more easily, thereby reducing the air resistance in the air conditioner indoor unit 10 better.

[0046] In some embodiments of the present application, as shown in the figure, Figure 1 As shown in the figure, the air conditioner indoor unit 10 can further include a top air outlet part 96 and a third partition 91. The top air outlet part 96 is arranged above the mounting shell 1, and the top air outlet part 96 defines a top air outlet air duct 97 communicating with the centrifugal air duct 21. After the airflow flows into the centrifugal air duct 21, the airflow can flow into the top air outlet air duct 97, and then the airflow flows out of the air conditioner indoor unit 10 from the top air outlet air duct 97, thereby increasing the air outlet range of the air conditioner indoor unit 10.

[0047] Furthermore, the third partition 91 can be arranged in the top air outlet air duct 97, and the third partition 91 can separate the top air outlet air duct 97 into a left air duct 92 and a right air duct 93.
