Problems solved by technology

[0002] At present, the axial flow fans on the market, under the premise of ensuring that the outer size of the fan blades remain unchanged, in order to increase the air output of the fan, it is mainly by adjusting the parameters such as the angle and arc length of each blade in the fan blades or increasing the number of blades. However, simply adjusting the parameters such as angle and arc length has less room for improvement, so the effect of increasing the air output of the fan is not obvious; while increasing the number of blades to increase the air output of the fan, it is necessary to reduce the blade. The size of the blade will reduce the performance of a single blade, so the effect of improving the air output of the fan is not obvious

Abstract

The invention discloses a double-blade-fixing clustering fan blade structure, an axial fan and an air conditioner. The double-blade-fixing clustering fan blade structure comprises a blade fixing structure and at least one group of clustering blades, wherein the clustering blades comprise a first blade, a second blade and a third blade, the blade inner edge of the first blade and the blade inner edge of the second blade are correspondingly connected with the blade fixing structure, the second blade is correspondingly connected with the first blade and the third blade, and gaps exist between thefirst blade and the second blade, and / or between the first blade and the third blade, and / or between the second blade and the third blade. The double-blade-fixing clustering fan blade structure has the advantage of large air outlet amount, and the air outlet amount of the axial flow fan can be effectively increased.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a cluster fan blade structure with fixed double blades, an axial flow fan and an air conditioner. Background technique [0002] At present, the axial flow fans on the market, under the premise of ensuring that the outer size of the fan blades remain unchanged, in order to increase the air output of the fan, it is mainly by adjusting the parameters such as the angle and arc length of each blade in the fan blades or increasing the number of blades. However, simply adjusting the parameters such as angle and arc length has less room for improvement, so the effect of increasing the air output of the fan is not obvious; while increasing the number of blades to increase the air output of the fan, it is necessary to reduce the blade. Due to the size of the blade, the performance of a single blade will be reduced, so the effect of increasing the air output of the fan is not obvio...
