Problems solved by technology

[0002] At present, the split air conditioner mainly includes structures such as cross-flow fan blades, heat exchangers, volute tongues, inlets and outlets. The cross-flow fan blades work in combination with the heat exchanger. The air is sent to the indoor side through the outlet. When the cross-flow fan blade rotates, the continuous interaction between the airflow and the volute tongue will generate rotating noise, which will affect the user experience.

Embodiment Construction

[0047] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an air conditioner indoor unit in the prior art; the air conditioner indoor unit in the prior art mainly includes a heat exchanger 10, a cross-flow fan blade 20, a volute tongue 30, an inlet 40 and an outlet 50, and the heat exchanger 10 is used for heat exchange. The cross-flow vane 20 is used to perform work on the airflow and rotate to send it to the space, and the functions of the cross-flow vane 20 and the heat exchanger 10 are completed independently of each other.

[0048] Please also refer to Figure 2 to Figure 5 , figure 2 is a schematic diagram of the cross-flow fan blade; image 3 is a schematic diagram of the explosion structure of the cross-flow blade; Figure 4 and Figure 5 Schematic diagrams of the structure of the mid-section wind blade under different viewing angles. The cross-flow blades 20 commonly used in the prior art include at least 5 intermediate blades 21 and le...

Abstract

The invention provides wind deflector blades, cross-flow fan blades and an air conditioner. The blades (1) are used for the cross-flow fan blades, each blade (1) includes two ends oppositely arrangedin a first direction, and the first direction is the length direction of the cross-flow fan blades. The surfaces of the blades located between the two ends form alternately arranged concave portions and convex portions along with the width direction of the blades. Through the concave portions and the convex portions, the airflow distribution on the surface of the blades (1) can be changed, eddy current generation can be avoided, the noise caused by the airflow separation on the surfaces of the blades (1) and the interaction between the blades (1) and a casing can be reduced, thereby effectively improving the comfort of the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a blade, a cross-flow fan blade and an air conditioner. Background technique [0002] At present, the split air conditioner mainly includes structures such as cross-flow fan blades, heat exchangers, volute tongues, inlets and outlets. The cross-flow fan blades work in combination with the heat exchanger. The air is sent to the indoor side through the outlet. When the cross-flow fan blade rotates, the continuous interaction between the airflow and the volute tongue will generate rotating noise, which will affect the user experience. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to provide a blade, a cross-flow fan blade and an air conditioner, which can reduce the noise generated when the cross-flow fan blade rotates, and improve user experience. [0004] In order to solve the above problems, th...
