20 rotation generates obstruction.
The working principle of the cross flow fan of the present embodiment are as follows: when motor rotates forward, wind wheel 20 is driven to turn counterclockwise
Dynamic, the first wind wheel section 21 and the second wind wheel section 22 rotate in the counterclockwise direction.The wherein blade of the first wind wheel section 21
23, blade profile curve bending extending direction is also counterclockwise that consistent with 20 direction of rotation of wind wheel, the first wind wheel section 21 can produce
Anger stream, and the flow direction of the air-flow is identical with the first duct-curve bending extending direction, therefore, the first exhaust air flue
121 being capable of outlet air.And the blade 23 of the second wind wheel section 22, blade profile curve bending extending direction be it is clockwise, with wind wheel 20
Direction of rotation is inconsistent, and the second wind wheel section 22 can not generate air-flow, and therefore, the second exhaust air flue 122 is unable to outlet air.It is multiple
The wind that first exhaust air flue 121 generates finally is flowed out along the export direction of the first air-supply passage 13, and the second air-supply passage 14 does not have
Have it is distinguished and admirable go out.
When motor rotates backward, wind wheel 20 is driven to rotate clockwise, the first wind wheel section 21 and the second wind wheel section
22 are rotated in the clockwise direction.The wherein blade 23 of the first wind wheel section 21, it is the inverse time that blade profile curve, which is bent extending direction,
Needle, inconsistent with 20 direction of rotation of wind wheel, the first wind wheel section 21 cannot generate air-flow, and therefore, the first exhaust air flue 121 cannot
Outlet air.And the blade 23 of the second wind wheel section 22, blade profile curve bending extending direction be it is clockwise, with 20 direction of rotation of wind wheel
Unanimously, the second wind wheel section 22 can generate air-flow, while the flow direction of air-flow and the second duct-curve are bent extending direction
Identical, therefore, the second exhaust air flue 122 being capable of outlet air.The wind that multiple second exhaust air flues 122 generate is finally logical along the second air-supply
The export direction in road 14 flows out, and the first air-supply passage 13 is not distinguished and admirable out.
It certainly, in other embodiments, may be due to the bending extension side of wind wheel 20 blade 23 and exhaust air flue 12
It is contrary to the setting with the present embodiment, when wind wheel 20 may be implemented rotating clockwise, 13 outlet air of the first air-supply passage；Wind wheel 20
When rotating counterclockwise, 14 outlet air of the second air-supply passage, such case those skilled in the art are readily appreciated that, are no longer carried out here
It repeats.
The cross flow fan of the present embodiment clockwise or counterclockwise by driving wind wheel 20 keeps wind logical from the first air-supply
The outflow of the export direction of road 13 or the second air-supply passage 14, realizes two-way ventilating function, and the equal independent air-feeding in each direction.This
The cross flow fan of embodiment is preferably used for the indoor unit of air conditioner, which can be set two different air outlets, passes through
The outlet of the first air-supply passage 13 and the second air-supply passage 14 of flow fan each communicates with an air outlet, to realize indoor unit
Two-way independent air-feeding function.
Present embodiments provide a kind of cross flow fan comprising: shell 10 and wind wheel 20.Shell 10 is formed with including inside

A first exhaust air flue 121 and at least one second exhaust air flue 122.Wind wheel 20 is set in accommodating chamber 110, and wind wheel 20 is matched
Axis can be rotated about it by being set to rotates clockwise or counterclockwise, and wind wheel 20 is divided into multiple wind along its pivot center direction
Section is taken turns, wind wheel section includes at least one the first wind wheel section 21 and at least one second wind wheel section 22, each first wind
The wind that wheel section 21 generates is discharged by first exhaust air flue 121, and the wind that each second wind wheel section 22 generates is by one the
The discharge of two exhaust air flues 122.Wherein, the first blade profile curve and the second blade profile curve bending extending direction are on the contrary, the first air duct is bent
Line and the second duct-curve be bent extending direction on the contrary, and the first blade profile curve and the first duct-curve be bent extending direction phase
Together.When the rotation counterclockwise (or clockwise) of wind wheel 20, the first exhaust air flue 121 being capable of outlet air.When wind wheel 20 is (or inverse clockwise
Hour hands) rotation when, the second exhaust air flue 122 being capable of outlet air.The cross flow fan of the present embodiment, by driving wind wheel 20 clockwise or
Rotation counterclockwise flows out wind from the export direction of the first air-supply passage 13 or the second air-supply passage 14, realizes two-way ventilating
Function, and the equal independent air-feeding in each direction.
Further, the cross flow fan of the present embodiment further include: the first air-supply passage 13 and the second air-supply passage 14.First
Air-supply passage 13 is connected to the ducting outlet 124 of each first exhaust air flue 121, so that into the first exhaust air flue 121
Wind flowed out by the first air-supply passage 13；Second air-supply passage 14 and the ducting outlet 124 of each second exhaust air flue 122 connect
It is logical, so as to be flowed out into the wind in the second exhaust air flue 122 by the second air-supply passage 14.First air-supply passage 13 and the second air-supply
The outlet in channel 14 extends along the length direction of volute section 11, so that cross flow fan has wind to go out in its entire transverse direction,
It blows more uniform.
Further, the junction of the two neighboring spiral case section 111 of the cross flow fan of the present embodiment is provided with baffle
114, above-mentioned baffle 114 is locating in accommodating chamber 110 to separate two neighboring wind wheel section to 110 internal stretch of accommodating chamber
Space is interfered with each other with preventing adjacent wind wheel section from rotating the wind to be formed.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
Determine or deduce out many other variations or modifications consistent with the principles of the invention.Therefore, the scope of the present invention is understood that and recognizes
It is set to and covers all such other variations or modifications.
