The current air-conditioning indoor unit products have various styles, and the internal structure mainly adopts a single air duct and a single cross-flow fan wheel for air supply structure. This structure has only one air duct, and the air outlet is located in the middle of the panel of the cylindrical cabinet, so the air volume of the air outlet is concentrated in front of the panel, and the air supply volume on both sides is small, even if the air guide strips are used, the air supply cannot be effectively increased. The angle results in a small air supply angle. When the fan is started, because the cross-flow wind wheel is vertically installed, the wind generated is generally horizontal. When heating, the temperature of the upper part of the indoor space is higher than the temperature of the bottom plate due to the rise of hot air.

In addition, the air supply mechanism of the indoor unit of the air conditioner is usually driven by an inner rotor motor. During installation, the motor shaft of the inner rotor motor is connected to the wind wheel, and the inner rotor is placed outside the wind wheel, which takes up a large installation space and is inconvenient for assembly and fixing operations. And when the internal rotor motor takes up a lot of space, it will inevitably cause the overall size of the indoor unit, which cannot meet the beautiful and delicate appearance requirements of the air conditioner, and its market competitiveness will also be greatly weakened. In order to meet the appearance requirements of the air conditioner, the structural design of the air conditioner must be compact, so the shape design of the inner rotor motor must not be too large, but when the shape of the inner rotor motor is too small, although it meets the compact requirements, sometimes it cannot meet the performance requirements. At this time, the motor is difficult to install, and there is not enough space inside the air supply device to dissipate heat for the motor, resulting in excessive temperature rise of the motor, and its speed and efficiency cannot meet the requirements of the air conditioner as a whole.
