Example Embodiment

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with 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, rather than all 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 shall fall within the protection scope of the present invention.

[0026] 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 that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a cross-flow wind wheel and an air conditioner. The cross-flow wind wheel includes two opposite end plates, and a cylindrical impeller arranged between the two end plates. The cylindrical impeller includes a plurality of The blade is arranged in an arc, and the blade is divided into an inner leaf part and an outer leaf part by a tangent plane perpendicularly bisecting the chord line of the blade, the surface area of ​​the outer leaf part is S1, and the surface area of ​​the inner leaf part is S2 , S2/S1 ∈ [1.15, 1.25]. The cross-flow wind rotor of the present invention can improve the airfoil shape of the cross-flow wind rotor to reduce the resistance of the air flow, thereby increasing the air volume of the cross-flow wind rotor and reducing the power of the cross-flow wind rotor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a cross-flow wind wheel and an air conditioner. Background technique [0002] Because of its simple structure and small size, the cross-flow wind wheel is widely used in household appliances and air-conditioning equipment as a ventilation device. The cross-flow wind wheel mainly includes two oppositely arranged end plates and a cylindrical impeller connected to the two end plates. The cylindrical impeller includes a plurality of blades. The upper blade gap enters, forms a flow vortex inside the cylindrical impeller, and finally flows out from the lower blade gap of the cross-flow rotor. Conventional cross-flow wind rotors mostly use arc-shaped blades, and the blades are divided into inner blades and outer blades by a cut plane that perpendicularly bisects the chord line connecting the blades, and the inner blades and outer blades are completely symmetrical about the cho...
