The motor 500 is arranged on the partition plate 170, and the motor 500 includes an indoor output shaft 510 coaxially arranged along the vertical direction with the impeller 420 and drivingly connected with the impeller 420.

[0099] Through the arrangement of the partition plate 170, the interior cavity of the shell 100 can be partitioned, and the motor 500 can be supported, so that the indoor fan assembly 400 can be driven while the compactness of the interior structure of the shell 100 is improved.

[0100] Optionally, the partition plate 170 is fixedly connected with the shell 100, and the partition plate 170 cooperates with the upper half of the shell 100 to define the indoor heat exchange cavity 103 and cooperates with the lower half of the shell 100 to define the outdoor heat exchange cavity 104. An outdoor fan assembly is arranged in the outdoor heat exchange cavity 104. The partition plate 170 is used to support the indoor heat exchanger 200, the indoor air duct assembly 300 and the indoor fan assembly 400.

[0101] Optionally, the motor 500 is a bidirectional motor including an indoor output shaft 510 and an outdoor output shaft. The partition plate 170 is provided with a mounting hole, and the motor 500 is sealingly mounted in the mounting hole. The indoor output shaft 510 of the motor 500 extends along the vertical direction and extends into the indoor heat exchange cavity 103 to be coaxially arranged with the impeller 420 of the indoor fan assembly 400 and drivingly connected with the impeller 420. In this way, the coaxial arrangement of the impeller 420 and the indoor output shaft 510 can improve the stability. In addition, the motor 500 and the indoor fan assembly 400 are arranged along the vertical direction, so that the compactness of the structure in the interior of the shell 100 is improved. Meanwhile, the motor 500 is drivingly connected with the outdoor fan assembly. The motor 500 can simultaneously drive the outdoor fan assembly and the indoor fan assembly 400. When the motor 500 operates, the rotation of the impeller 420 is driven, so that the indoor air is driven to flow from the indoor air inlet 101 of the shell 100 into the indoor heat exchange cavity 103, and after heat exchange with the indoor heat exchanger 200, the air flows to the indoor air outlet 102 through the indoor fan assembly 400.
