Abstract

Embodiments of the present invention provide a cross-flow fan and an air conditioner, wherein the cross-flow fan includes at least two supporting discs arranged at intervals, one of which is rotatably coaxially connected with a diverter; the supporting discs are spaced apart in the circumferential direction and A plurality of moving fan blades are swingably installed, and the plurality of moving fan blades are all connected to the diverter so as to swing relative to the support plate with the rotation of the diverter. The cross-flow fan improves the existing fixed fan blade structure, and can adjust the air outlet angle of the fan blade in real time according to the air volume demand, reduces the power waste of the main motor adjusting the speed of rotation, and prevents noise caused by excessive rotation speed.

Description

technical field [0001] The present invention relates to the technical field of air conditioning equipment, and in particular, to a cross-flow fan and an air conditioner. Background technique [0002] Air conditioner is a household equipment commonly used in our daily life. It can adjust parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or closed space, area) to meet the requirements of human comfort or process. At present, the cross-flow fan of the air conditioner indoor unit is widely used in air conditioners and small air supply equipment due to its excellent characteristics such as large flow, low noise, and stable air supply. The impeller of the cross-flow fan is multi-blade, long cylindrical, and has fixed forward multi-blade blades. During the operation of the air conditioner, one end of the cross-flow fan is rotatably installed on the casing, and the other end is driven by the main motor to rotate. The change of the air v...
