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 invention relates to the technical field of air-conditioning equipment, and more specifically, relates to an air conditioner and cross-flow fan blades thereof. Background technique [0002] Existing air conditioner structure such as figure 1 as 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 vane 1` and the volute tongue 2` determines the air volume and noise performance of the air conditioner. The cross-flow vane 1` is composed of 35 blades, each phase The angles between two adjacent blades are not equal to each other, such as figure 1 Among them, the included angle A, included angle B and included angle C refer to the angles between adjacent blades respectively, and the included angles are different. Therefore, when the cross-flow fan 1` rotates, each blade and the volute tongue The rotational phases between them are not equal. [0003] Such as ...
