[0049] Alternatively, if Figure 6 and Figure 7 As shown, the mounting groove 11 is an arc groove, and the inner wall surface of the arc groove matches the outer peripheral wall of the motor 2, thereby improving the reliability of fixing the motor 2. In addition, the side of the mounting groove 11 facing the wind wheel is open, thereby facilitating the connection between the output shaft of the motor 2 and the wind wheel.

The second mounting ear 31 is located on the side of the first mounting ear 211 away from the chassis 1, and the second mounting ear 31 has a second mounting hole 32 for the fastener 33 to pass through, thereby limiting the first mounting ear 211 between the chassis 1 and the second mounting ear 31, limiting the first mounting ear 211 from moving in the up and down direction, thereby limiting the motor 2 from moving in the up and down direction. In addition, the fixing structure of the motor 2 of the present application is simple, and the corresponding fixing structure of the motor cover 3 is simple, which improves the assembly efficiency of the whole machine of the air conditioner indoor unit 100 and the convenience of after-sales maintenance.

[0054] According to the air conditioner indoor unit 100 of the embodiment of the utility model, by adopting an outer rotor motor, the length of the matching fuselage can be shortened, which is conducive to the miniaturization and cost reduction of the air conditioner indoor unit 100. In addition, the fixing structure of the motor 2 of the present application is simple, so that the fixing structure of the motor cover 3 is simple, which improves the assembly efficiency of the whole machine of the air conditioner indoor unit 100 and the convenience of after-sales maintenance.

It can be understood that the protrusion 41 is provided between the limiting protrusion 212 and the limiting groove 12, so that the first vibration damping pad 4 can completely cover the bottom wall of the fixing bracket 21 of the motor 2, thereby better isolating the vibration between the motor 2 and the chassis 1, and reducing the vibration transmitted from the motor 2 to the chassis 1.

[0061] Specifically, the limiting protrusions 212 are multiple and spaced apart along the axial direction of the motor 2, and the protrusions 41 are multiple and correspond one to one with the multiple limiting protrusions 212. Fig.11 In the example shown, there are two limiting protrusions 212 spaced apart along the axial direction of the motor 2 , and there are two protrusions 41 corresponding to the two limiting protrusions 212 one by one.
