Abstract

The utility model relates to an axial-flow fan used for an air conditioner indoor machine. The utility model comprises a blade and a flange plate, wherein, the cylinder-shaped axial-flow fan is cut into a plurality of small section fans along a radial direction by the flange plate. The cylinder-shaped axial-flow fan is cut into odd numbers of small section fans along the radial direction by even numbers of flange plates. Each blade of a middle small section fan is parallel in an axial direction to the cylinder-shaped axial-flow fan. Air can be blown to the middle part of an air outlet through the middle small section fan. Thus, the utility model has the advantage of complete air direction and has no noise increase.

Description

A kind of air conditioner axial-flow fan
The utility model relates to the axial-flow fan that uses in a kind of indoor apparatus of air conditioner.
In the prior art, the axial-flow fan in the indoor apparatus of air conditioner, it is to be arranged in parallel that blade and fan axis are arranged, the shortcoming of this kind structure is that noise is bigger.For reducing noise, the structure with the relative fan shaft inclination of blade several angle is also arranged, but this kind structure makes that wind can only be to certain folk prescription to blowing out, and limited air output.Existing patent 97240300 discloses a kind of structure of axial-flow fan, for further reducing noise, it has the odd number flange plate that axial-flow fan is cut into even number segment fan, each blade in the segment fan and fan shaft to angle be identical, the blade of at least two segment fans 3 and fan shaft to angle be that symmetry is identical.The arrangement of its blade roughly has two kinds of forms: the one, and be symmetry axis with the flange plate 1 of centre, the blade 2 on both sides is " V " font to be arranged, as shown in Figure 1; Though the fan of said structure has reduced noise to a certain extent, but still have the dead angle on the wind direction, promptly wind can only be the more important thing is and limit air output to the folk prescription on both sides to blowing out.
The purpose of this utility model is to provide a kind of noise that both made lower, again the axial-flow fan that the wind direction omnirange is blown out.
For achieving the above object, the utility model has adopted following technological scheme: a kind of air conditioner axial-flow fan, comprise blade and flange plate, blade forms the tubular axial-flow fan along the circumferential arrangement of flange plate, flange plate radially is cut into several segment fans with the tubular axial-flow fan, it is characterized in that described tubular axial-flow fan is by the even number flange plate tubular axial-flow fan radially to be cut into odd number segment fan, each blade in the middle segment fan axially parallels with the tubular axial-flow fan, and the axial angle of each blade in each segment fan of the segment fan both sides of centre and tubular axial-flow fan is identical.
The axial angle of the blade of each segment fan of middle segment fan both sides and tubular axial-flow fan is that the segment fan with the centre is a symmetry axis and symmetrical identical.
In each segment fan of middle segment fan both sides, the axial angle of the blade of adjacent segment fan and tubular axial-flow fan is to be symmetry axis and symmetrical identical with between the two flange plate.
Owing to adopted technique scheme, the blade of the middle segment fan of the utility model fan parallels with fan shaft, so when blowing, wind can blow out to the centre of exhaust outlet by the segment fan of centre, makes wind direction more complete, also can not increase noise simultaneously.
The structural representation of Fig. 1 patent 97240300 disclosed axial-flow fans
Fig. 2 the utility model embodiment 1 structural representation
Fig. 3 the utility model embodiment 2 structural representation
Below in conjunction with drawings and Examples the technical solution of the utility model is further described.
As shown in Figure 2: axial-flow fan of the present utility model, comprise blade 4 and flange plate 5, blade 4 forms the tubular axial-flow fan along the circumferential arrangement of flange plate 5, flange plate 5 radially is cut into several segment fans 6 with the tubular axial-flow fan, described tubular axial-flow fan is by even number flange plate 5 the tubular axial-flow fan radially to be cut into odd number segment fan 6, each blade 4 in the middle segment fan 7 axially parallels with the tubular axial-flow fan, and the axial angle of each blade 4 in each segment fan 6 of segment fan 7 both sides of centre and tubular axial-flow fan is identical.In the present embodiment, the axial angle of the blade 4 of each segment fan 6 of middle segment fan 7 both sides and tubular axial-flow fan is that the segment fan 7 with the centre is a symmetry axis and symmetrical identical, the quantity of its flange plate 5 is eight of even numbers, and the quantity of segment fan 6 is seven of odd numbers.
As shown in Figure 3: in each segment fan 6 of middle segment fan 7 both sides, the axial angle of the blade 4 of adjacent segment fan and tubular axial-flow fan is to be symmetry axis and symmetrical identical with between the two flange plate 5.
