Problems solved by technology

The air supply system with a single blade mentioned above has low air supply efficiency due to the limitation of the blades
[0003] In the prior art, there is also a double-blade air supply system formed by combining centrifugal blades and axial flow blades, which can improve the air supply efficiency to a certain extent. Solid assembly, the combination of the two is integrally injected, the mold is relatively complicated, and the two fan blades can only rotate at the same time, the speed is the same, and the air supply efficiency is not significantly improved

Abstract

The invention relates to a double-blade air supply system and an air conditioner, wherein the double-blade air supply system comprises a centrifugal blade, an axial flow blade and a gear transmission mechanism; the axial flow blade is arranged in the centrifugal blade; and the axial flow blade and the centrifugal blade form differential rotation through the gear transmission mechanism. The axial flow blade and the centrifugal blade can be separately and plastically molded, so that a mold is simplified, and the complexity of the mold is reduced; and the axial flow blade and the centrifugal blade are assembled for use, and the differential rotation of the two blades can be realized through the gear transmission mechanism, so that the air supply efficiency is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a double-blade air supply system and an air conditioner. Background technique [0002] Household appliances such as air conditioners use a single fan blade air supply system, for example: 1) a single centrifugal fan blade, when rotating, the surrounding pressure is low and the middle pressure is high, so that the air moves from the surrounding to the middle, and then flows from the axial direction. Blowing out in one direction realizes suction around and blows air in the middle; 2) Single axial flow fan blade realizes axial air in and out; 3) Single perfusion fan blade realizes radial air supply with air duct. The air supply system of the above-mentioned single fan blade has low air supply efficiency due to the limitation of the fan blade. [0003] In the prior art, there is also a double-blade air supply system formed by combining centrifugal blades and axial flow blades, wh...
