The casing 10 is a main body of an air conditioning indoor unit, and for a wall-mounted air conditioning indoor unit, the casing 10 can be horizontally mounted on a wall of an air conditioning room. The casing 10 is provided with a fresh air duct, which is a passage used by the fresh air module and is a place for exchanging indoor air and outdoor air. The heat exchange air duct is a channel used by a heat exchange module of the air conditioner indoor unit and is a place for heat exchange refrigeration or heating of air in the air conditioner room. Specifically, the cross-flow impeller 9 is installed in the heat exchange air duct and used for blowing the air after heat exchange into the indoor environment through the air outlet hole of the casing 10. Centrifugal wind wheel 4 installs in the new trend wind channel, and centrifugal wind wheel 4 produces the negative pressure in order to inhale the new trend wind channel with outdoor fresh air in the new trend wind channel, and then inputs to indoor.

The left end of the first half shaft 2a is connected with the second half shaft 2b through a coupling. In order to save space inside the casing 10, the first half-shaft 2a and the second half-shaft 2b are coaxial. The second half shaft 2b extends leftwards from the heat exchange air duct to the fresh air duct and is connected with the centrifugal wind wheel 4, so that the centrifugal wind wheel 4 is driven to rotate. At this time, referring to fig. 1, the escape recess 401 originally used for mounting the centrifugal motor on the end surface of the centrifugal wind wheel 4 can be used for mounting the bearing, so that the second half shaft 2b can normally rotate in the casing.

At least part of the first half shaft 2a, the coupling 3 and at least part of the second half shaft 2b are all disposed in the connecting pipe 901, and the first half shaft 2a is connected with the connecting pipe 901.
Specifically, the connection tube 901 can be installed in the casing 10 through bearings at both ends, so as to drive the impeller assembly 902 sleeved on the connection tube 901 to rotate. The pipe inside connection pipe 901 penetrates connection pipe 901 in the axial direction of connection pipe 901. The first half shaft 2a extends from the driving motor 1 and enters the connecting pipe 901, and the first half shaft 2a is connected to the connecting shaft 901, so that the first half shaft 2a drives the connecting pipe 901 to rotate around the axis of the connecting pipe 901, and the impeller set 902 to rotate.

Specifically, the drive motor 1 is provided between the turbine impeller 9 and the centrifugal wind wheel 4. As will be readily appreciated, since the centrifugal wind wheel 4 generally has an avoidance recess 401 for mounting the motor, in the present embodiment, the avoidance recess 401 is used for mounting the driving motor 1. In this embodiment, in the casing 10 of the indoor unit of the air conditioner, the centrifugal wind wheel 4, the driving motor 1, and the cross-flow wind are sequentially arranged from left to right, so that the space inside the casing 10 is fully utilized.

For example, the fourth half shaft 2d may be directly and fixedly connected with the connecting shaft of the through-flow impeller 9, so as to drive the connecting shaft and the impeller set 902 thereon to rotate, i.e. the through-flow impeller 9 rotates. The fixed connection can be a coupling connection, a bushing connection or other equivalent ways.
Compared with the case that the driving motor 1 is arranged on one side of the casing 10, the driving motor 1 is arranged in the middle of the casing 10, namely between the cross-flow impeller 9 and the centrifugal wind wheel 4, so that the length of the output shaft can be reduced, the vibration of the output shaft is further reduced, the situation that the output shaft extends from the right end of the casing 10 to the left end of the casing 10 so that the casing 10 is driven to vibrate when the output shaft rotates is avoided, and the indoor unit of the air conditioner is more stable and quiet when in operation.

Also make the temperature of sending into indoor new trend be close to or unanimous with the settlement temperature in the air conditioner room, avoid sending into the new trend and original room air between the difference in temperature too big, avoid because the too big influence user's that leads to of difference in temperature travelling comfort experience.
And fresh air is sent between the heat exchanger 11 and the casing 10, and the influence on the air inlet of the heat exchanger 11 after the fresh air enters the heat exchange air duct can be avoided.
