Abstract

The invention discloses an axial flow fan, a control method of the axial flow fan and an air conditioner. The axial flow fan comprises a motor, a first wind wheel and a second wind wheel. The motor comprises a motor shell, a first rotating shaft and a second rotating shaft, wherein the first rotating shaft and the second rotating shaft extend from the same side of the motor shell, the first rotating shaft sleeves the outer side of the second rotating shaft, and the first rotating shaft and the second rotating shaft rotate independently. The first wind wheel comprises a first hub and a first blade arranged on the first hub, the first hub is mounted on the first rotating shaft, a mounting cavity is formed in the hollow first hub and against an opening of the motor, and the second rotating shaft extends into the mounting cavity from the first rotating shaft. The second wind wheel is mounted on the second rotating shaft and is arranged in the mounting cavity. According to the technical scheme, the axial flow fan has the advantages of good air supply effect and multiple air supply modes.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an axial flow fan, a control method thereof and an air conditioner. Background technique [0002] Conventional fans mostly use a single-axis motor as a power component to drive the wind wheel to rotate. However, the blower fan with a single wind rotor has poor air supply effect, and there are problems such as narrow air supply area and short air supply distance. The two output shafts of the double-axis motor protrude from opposite ends of the motor casing, and drive the two wind wheels to rotate at the same time. But because there is a motor between the two wind wheels, the airflow between the two wind wheels is prone to turbulence, the air supply effect of the fan is not significantly improved, and the two output shafts can only rotate at the same speed synchronously, and cannot work independently. The air supply mode is single. Contents of the invention [0003] The main pu...
