That is to say, the bending directions of the first flange 2121 and the second flange 213 are opposite. Thus, in the up and down direction, the first flange 2121, the second flange 213, the cross section of the part of the support body 21 between the first flange 2121 and the second flange 213 can form a Z-shaped structure (as shown in FIG. 7 and Fig. 8), effectively smooth the flow direction of the airflow, reduce the resistance, reduce the eddy current on the motor support 2, thereby reducing the noise, and at the same time, due to the reduction of the resistance, the air volume of the air conditioner 100 has also been improved. improve.

For example, as shown in Figure 1, the air flow flows in the direction indicated by the arrow in Figure 1, when the first flange 2121 is bent along the direction of the air flow, the second flange 213 is bent along the opposite direction of the air flow; When the first flange 2121 is bent in the opposite direction of the air flow, the second flange 213 is bent in the direction of the air flow. As shown in FIG. 1 , FIG. 11 and FIG. 12 , the motor base 22 is disposed at the mounting hole 211 and connected to the bracket main body 21 . Thus, the reliability of the connection between the motor base 22 and the bracket main body 21 can be increased.

According to the motor bracket 2 of the air conditioner 100 according to the embodiment of the present utility model, the first flange 2121 on the side wall of the ventilation hole 212 and the second flange 213 on the side wall of the bracket body 21 are aligned in the flow direction of the airflow, Bending in the opposite direction can effectively smooth the flow direction of the airflow and reduce the resistance of the airflow, thereby reducing the eddy current on the motor bracket 2 and reducing the noise generated by the airflow. At the same time, due to the reduction of resistance, the air volume of the air conditioner 100 can be increased.

In some embodiments of the present invention, as shown in Fig. 2 and Fig. 3, the bracket body 21 is provided with a connector 214 (the connector 214 positioned at the back side of the bracket body 21), and the connector 214 is cut by the bracket body 21. Forming, the cut part of the bracket main body 21 is formed as a ventilation hole 212 , and there is a gap 215 between the first flange 2121 on the ventilation hole 212 and the connecting piece 214 . When the connecting piece 214 is not cut, the connecting piece 214 and the bracket body 21 are located on the same plane and the connecting piece 214 is a part of the bracket body 21.
