Abstract

The invention provides an impeller assembly, a fan and air conditioning equipment. The impeller assembly comprises flexible transmission parts and a plurality of blades, wherein the flexible transmission parts are connected end to end to form a loop and rotationally arranged along the loop; the plurality of blades are connected onto the flexible transmission parts and arranged in the extension direction of the flexible transmission parts. With the adoption of the technical scheme, the plurality of blades are driven by the flexible transmission parts to rotate around the loop formed by the flexile transmission parts, the air suction surface of the fan can be changed according to the shape of the loop defined by the flexible transmission parts, and the problem that air suction surfaces of fans cannot be changed in the prior art is solved.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to an impeller assembly, a fan and air-conditioning equipment. Background technique [0002] figure 1 A schematic structural view of an axial-flow impeller assembly in the prior art is shown, such as figure 1 As shown, the axial-flow fan blades in the prior art all adopt the method of arranging a plurality of axial-flow blades 1' in the circumferential direction of a rotating shaft. Although such axial-flow blades 1' can be designed to be thinner, they are limited by the rotating area. The air suction area is limited, and in order to obtain a large air volume or a large air inlet and outlet area, several fans need to be connected in parallel. The wind field is very uneven. [0003] The air suction surface of the axial flow fan in the prior art is a circular surface centered on the rotating shaft, and the air suction surface cannot be changed and is limited. [0004] f...
