Embodiment Construction

[0027] The invention discloses a cross-flow fan blade, which solves the noise problem caused by the air flow at the air outlet of the cross-flow fan blade; the invention also provides an air conditioner.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0029] like image 3 shown, image 3 It is a schematic diagram of the first preferred offset structure of the blade of the cross-flow fan blade provided by the present invention.

Abstract

The invention provides a cross flow blade. The cross flow blade comprises multiple middle-section blades coaxially connected, wherein stagger angles are respectively formed between any adjacent two middle-section blades; and the deflection directions of the stagger angles between the blades with the same structure in at least one set of adjacent middle-section blades are oppositely arranged. The deflection directions of the stagger angles between one set of the middle-section blades in the cross flow blade are set as directions opposite to original deflection directions, the blades of the middle-section blades of the cross flow blade in the same generatrix position are deviated from the generatrix to return to the generatrix position, and the blades of the cross flow blade with the same structure are distributed near the generatrix of the cross flow blade in the length direction of the cross flow blade, so that the problem of air outlet ununiformity of the cross flow blade in the same generatrix position is solved to a certain extent, the air outlet uniformity of an indoor unit is improved, and airflows blown to a worn tongue prevent products from generating instable abnormal noise to improve the tone quality of the indoor unit. The invention further provides an air conditioner.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and more particularly, to an air conditioner and its cross-flow fan blades. Background technique [0002] The structure of the existing air conditioner is figure 1 shown, figure 1 It is a schematic diagram of the internal structure of the air conditioner in the prior art. The gap area between the cross-flow fan blade 1' and the volute tongue 2' determines the air volume and noise performance of the air conditioner. The cross-flow fan blade 1' consists of 35 blades. The angle between two adjacent blades is not equal to each other, such as figure 1 Among them, the included angle A, the included angle B and the included angle C refer to the angles between the adjacent blades respectively, and the included angles are different from each other. The rotation phase between them is unequal. [0003] like figure 2 shown, figure 2 It is a schematic structural diagram of a cross-flo...
