Problems solved by technology

[0003] The fan blade in the traditional technology mainly includes the hub and the fan blade installed on the hub. When the fan blade rotates, the rotation center area of ​​the hub will form a negative pressure zone, and the high-speed airflow flowing through the fan blade will be sucked into the negative pressure zone. Inside, this part of the high-speed airflow will collide with the high-speed airflow around the negative pressure area, resulting in greater noise when the fan blades are running

Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] An embodiment of the present invention provides a fan blade, which can be used in air conditioners, fans, and other equipment, and can be axial flow fan blades, centrifugal fan blades, and other types of fan blades. Such as figure 1 Shown is an assembly schematic diagram of an axial flow fan installed on an air conditioner. With reference to the structure of the axial flow fan, the fan blade provided by the embodiment of the present invention may include a hub 110 , a fan blade 120 and a flow guide part 130 . The hub 110 may adopt a rotary structure, and a driving mechanism (such as a motor) is fixedly connected to the hub 110 to drive the hub 110 to rotate. Fan blades 120 are usually arranged in multiples, and one end of each fan blade 1...

Abstract

The invention discloses a fan blade which comprises a hub (110), a fan leaf (120) installed on the hub (110) and a diversion part (130) installed on the hub (110), wherein the diversion part (130) is arranged in the rotational center region of the hub (110); the outer surface of the diversion part (130) is provided with a barrier surface (131); and the barrier surface (131) blocks in a track of gas flowing toward the rotational center region of the hub (110). According to the fan blade, when the fan blade rotates, the rotational center region of the hub has a tendency of forming a negative pressure region; with arrangement of the diversion part, when flowing toward the rotational center region, the gas can be blocked by the barrier surface, so that the quantity of the gas which enters the rotational center region of the hub is lowered to some extent, collision of the gas and an ambient high-speed gas flow after the gas enters the rotational center region of the hub is relieved, and therefore, the produced noise is weaker when the fan blade runs. The invention also discloses an air conditioner.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a fan blade. The invention also relates to an air conditioner. Background technique [0002] In the technical field of fluid machinery, the fan blades are used in a wide range of applications. For example, in an air conditioner, a motor is used to drive the fan blades to rotate, so as to realize the flow of air and achieve the purpose of temperature regulation. [0003] The fan blade in the traditional technology mainly includes the hub and the fan blade installed on the hub. When the fan blade rotates, the rotation center area of ​​the hub will form a negative pressure zone, and the high-speed airflow flowing through the fan blade will be sucked into the negative pressure zone. Inside, this part of the high-speed airflow will collide with the high-speed airflow around the negative pressure area, resulting in greater noise when the fan blades are running. Contents of t...
