[0040] Currently, the fan and output shaft of the embedded air conditioner are usually fixed by screws.

[0041] When repairing the motor, the screws between the motor and the fan need to be removed first before the motor can be removed. Since the fan shaft will rotate when the screws are removed, the screws are difficult to remove, which increases the difficulty of removing the motor.

[0042] Combination Figure 1-6 As shown, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including a fan 10 and a motor 20.

[0043] Combination Figure 5-6 As shown, the motor 20 is drivingly connected to the fan 10; wherein, a first limiting portion 12 cooperating with the disassembly tool 30 is provided on the fan 10, and the disassembly tool 30 cooperates with the first limiting portion 12 to limit the axial rotation of the fan 10 along its fan shaft 11; and / or, a second limiting portion cooperating with the disassembly tool 30 is provided on the motor 20, and the disassembly tool 30 cooperates with the second limiting portion to limit the axial rotation of the motor 20 along its output shaft 21.

[0044] The indoor unit of the air conditioner provided by the embodiment of the present disclosure can provide a restraining force in the axial rotation direction of the fan shaft 11 of the fan 10 by cooperating with the first limiting portion 12, so as to limit the fan 10 and restrict the rotation of the fan 10 along the axial direction of the fan shaft 11. The disassembly tool 30 can provide a restraining force in the axial rotation direction of the output shaft 21 of the motor 20 by cooperating with the second limiting portion, so as to limit the rotation of the motor 20 along the axial direction of the output shaft 21. The disassembly tool 30 can cooperate with the first limiting portion 12 or the second limiting portion, so as to limit the axial rotation of the fan 10 or the motor 20 during the disassembly process of the motor 20, thereby reducing the difficulty of disassembling the motor 20 and improving the efficiency of disassembling the motor 20.

[0046] By providing a first depression 13 or a first protrusion in the outer surface of the fan 10, a non-smooth surface portion is formed in the outer surface of the fan 10, which can provide a stable mating surface for the disassembly tool 30. The disassembly tool 30 can be closely abutted against the first depression 13 or the first protrusion, so that the disassembly tool 30 can be more stably matched with the fan 10, thereby providing the necessary restraining force in the axial rotation direction of the fan shaft 11 of the fan 10 during the disassembly process, so that the fan 10 will not move axially due to external forces. At the same time, the provision of the first depression 13 or the first protrusion can also enable maintenance personnel to quickly locate the mating point of the disassembly tool 30, thereby speeding up the disassembly speed of the motor 20 and improving maintenance efficiency.

[0047] Optionally, the second limiting portion includes a second recess or a second protrusion provided in the outer surface of the output shaft 21 , and the disassembly tool 30 is suitable for abutting against the second recess or the second protrusion.

[0048] By providing a second depression or a second protrusion in the outer surface of the output shaft 21, a non-smooth surface portion is formed in the outer surface of the output shaft 21, which can provide a stable mating surface for the disassembly tool 30. The disassembly tool 30 can be closely abutted against the second depression or the second protrusion, so that the disassembly tool 30 can be more stably mated with the output shaft 21, thereby providing the necessary restraint force in the axial rotation direction of the motor 20 along the output shaft 21 during the disassembly process, so that the motor 20 will not move axially due to external force. At the same time, the provision of the second depression or the second protrusion can also enable maintenance personnel to quickly locate the mating point of the disassembly tool 30, thereby speeding up the disassembly of the motor 20 and improving maintenance efficiency.

[0050] The first plane 14 can provide a flat and uniform contact surface for the disassembly tool 30 on the outer surface of the fan 10, so that the disassembly tool 30 can contact the first limiting portion 12 more stably, avoiding or reducing the sliding or misalignment of the disassembly tool 30 due to unstable contact, and improving the matching accuracy of the disassembly tool 30 and the first limiting portion 12.

[0051] It can be understood that the first plane 14 can be a plane formed by the first recess 13 (such as Figure 2 As shown), it can also be a plane on the first protrusion.

[0052] Optionally, the second limiting portion includes a second plane provided on the outer surface of the motor 20 , and the disassembly tool 30 is suitable for abutting against the second plane.

[0053] The second plane can provide a flat and uniform contact surface for the disassembly tool 30 on the outer surface of the motor 20, so that the disassembly tool 30 can contact the second limiting portion more stably, avoiding or reducing the sliding or misalignment of the disassembly tool 30 due to unstable contact, and improving the matching accuracy of the disassembly tool 30 and the second limiting portion.

[0054] It can be understood that the second plane can be a plane formed by the second recess, or a plane on the second protrusion.

The first limiter 12 is parallel to the axis of the first connection hole 15. During the disassembly of the motor 20, the disassembly tool 30 cooperates with the first limiter 12 to apply a restraining force at least perpendicular to the axis of the first connection hole 15 to the fan 10, effectively limiting the rotation of the fan 10 along the axial direction of its fan shaft 11, so that the fan 10 remains fixed during the disassembly of the motor 20, and the fastener can be disassembled more conveniently and quickly. The second limiter is parallel to the axis of the first connection hole 15. During the disassembly of the motor 20, the disassembly tool 30 cooperates with the second limiter to apply a restraining force at least perpendicular to the axis of the first connection hole 15 to the motor 20, effectively limiting the rotation of the motor 20 along the axial direction of its output shaft 21, so that the motor 20 remains fixed during the disassembly of the motor 20, and the fastener can be disassembled more conveniently and quickly.

[0062] When the fan shaft 11 is sleeved on the outside of the output shaft 21, the first limiter 12 is provided on the fan shaft 11 of the fan 10, and the disassembly tool 30 cooperates with the first limiter 12, which can effectively limit the fan 10 from rotating along the axial direction of the fan shaft 11 during the disassembly process, thereby reducing the difficulty of disassembling the motor 20. When the output shaft 21 is sleeved on the outside of the fan shaft 11, the second limiter is provided on the output shaft 21 of the motor 20, and the disassembly tool 30 cooperates with the second limiter, which can effectively limit the motor 20 from rotating along the axial direction of the output shaft 21 during the disassembly process, thereby reducing the difficulty of disassembling the motor 20.

[0063] Optionally, combined Figure 4 As shown, the fan shaft 11 is sleeved on the outer surface of the output shaft 21 , and the first limiting portion 12 is provided on the outer surface of the fan shaft 11 .
