Abstract
The utility model relates to a cross flow fan for an air conditioner. The cross flow fan for an air conditioner comprises blades and flange plates. A plurality of blades are arranged along the circumference of the flange plate, forming a barrel shape. A certain included angle is formed between the blades and the axial direction of a barrel. The blades are not distributed at equal distances along the circumference of the flange plate. The utility model is characterized in that the blades are cut into small sections of fans with an odd quantity with flange plates with an even quantity. An included angle between each blade of the same small section of fan and the axial direction of the fan is the same. In addition, the blade of at least one small section of fan is parallel to the axial direction of the fan. The utility model has the advantages of concentrated air force, air distance extension and great air outlet volume.
Description
The utility model relates to a kind of axial-flow fan of air conditioner.
In No. 97240300.0 patents, disclosed a kind of air conditioner axial-flow fan, it has blade and flange plate, a plurality of blades form the tubular axial-flow fan along the circumferential arrangement of a pair of flange plate, blade and tubular axial-flow fan axially be certain included angle, blade is not equally spaced along the circumference of flange plate, other has the odd number flange plate that above-mentioned tubular axial-flow fan is cut into even number segment fan vertically, each blade in each segment fan and fan shaft to angle be identical, the blade that wherein has two adjacent segment fans at least and fan shaft to angle be that symmetry is identical, promptly have at least the blade of two segment fans to be in the shape of the letter V or anti-V font between them.This fan can reduce noise, but still has wind-force to concentrate the shortcoming that air output is big inadequately inadequately.
The purpose of this utility model provides a kind of air conditioner axial-flow fan, and it can remedy the above-mentioned deficiency of existing axial-flow fan.
The utility model comprises blade and flange plate, a plurality of blades form tubular along the circumferential arrangement of flange plate, blade and this axially be certain included angle, blade is not equally spaced along the circumference of flange plate, it is characterized in that total even number flange plate is cut into odd number segment fan vertically with blade, with each blade in a bit of fan and fan shaft to angle be identical, and the blade that has a segment fan at least and fan axially is parallel.
The utility model has the advantages that wind concentration, wind is apart from lengthening, and air output is big.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, present embodiment comprises blade (1) and flange plate (2), a plurality of blades (1) form the tubular axial-flow fan along the circumferential arrangement of flange plate (2), the blade (1) on the middle a pair of flange and the parallel to an axis of tubular axial-flow fan, other has 4 pairs of i.e. 8 flange plate (2), and they are distributed in the both sides of above-mentioned a pair of flange and above-mentioned tubular axial-flow fan is cut out 8 segment fans vertically again.Each blade (1) in these segment fans and fan shaft to angle be identical.Like this, the distribution of the blade of present embodiment looks and is " table mountain " shape or anti-" table mountain " shape.
Claims (1)
