Problems solved by technology
However, during the working process of conventional axial-flow wind rotors, part of the airflow flows radially along the blades of the axial-flow wind rotors under the centrifugal force, resulting in a large loss of radial air volume of the axial-flow wind rotors. The air supply volume of the wind rotor is reduced, which will easily lead to an increase in the energy consumption of the axial flow wind rotor

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0029] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0030] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses an axial flow wind wheel and an air conditioner. The axial flow wind wheel includes a wheel hub, and a first set of fan blades and a second set of fan blades which are arrangedon the wheel hub; the first set of fan blades includes multiple long fan blades; the second set of fan blades includes multiple short fan blades; the multiple long fan blades and the multiple short fan blades are in interval arrangement; the axial flow wind wheel also includes a wind collecting cylinder which is coaxial with the wheel hub and in cylindrical arrangement; the cylinder wall of the wind collecting cylinder is successively connected to the middle parts of the multiple long fan blades; the first set of fan blades is located on the inner side of the wind collecting cylinder; and theouter blade edge of each short fan blade and the wind collecting cylinder are in interval arrangement. Thus, wind quantity flowing along the radial direction of the axial flow wind wheel can be decreased, so that the axial wind supply volume of the axial flow wind wheel can be increased.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an axial flow wind wheel and an air conditioner. Background technique [0002] Axial flow wind wheels are often used in household appliances or air conditioners as ventilation devices. When the axial-flow wind wheel is working, it drives the air in the circumferential direction to rotate to form an airflow, and drives the airflow to blow out along the axial direction of the axial-flow wind wheel. However, during the working process of the conventional axial flow rotor, part of the airflow flows radially along the blades of the axial flow rotor under the centrifugal force, resulting in a large loss of radial air volume of the axial flow rotor. The reduction of the air supply volume of the wind rotor easily leads to the increase of the energy consumption of the axial flow wind rotor. Contents of the invention [0003] The main purpose of the present invention is to pro...
