Two or more.
Referring to Fig. 2 and Fig. 3, the air-cooled ducted air conditioner in the present embodiment, including casing 1, in casing 1, it is provided with centrifugal blower 2 and evaporation
Device 4, centrifugal blower 2 includes spiral case 21 and the impeller 22, the air outlet 23 of spiral case 21 and vaporizer 4 phase that are arranged in spiral case 21
Right, it is provided with flow guide bar 3 at the air outlet 23 of spiral case 21, the bearing of trend of flow guide bar 3 is parallel with the rotation centerline of impeller 22, leads
At least a portion of stream bar 3 is located on the air-out path tangent with described impeller 22 edge.
Due to being provided with flow guide bar 3, the center of rotation of the bearing of trend of flow guide bar 3 and impeller 22 at the air outlet 23 of spiral case 21
Line is parallel, and at least a portion of flow guide bar 3 is located on the air-out path tangent with impeller 22 edge, and such flow guide bar 3 is just permissible
The air outlet 23 changing spiral case 21, to the wind direction between vaporizer 4, especially changes the wind blowing out wind along at impeller 22 outer rim tangent line
To, because the wind at this quickly and has certain static pressure, make it lose certain energy by changing the wind direction of wind at this, from
And reducing wind speed and static pressure, when this wind passes through to vaporizer 4 and between fin, the abnormal vibrations of fin will subtract significantly
Weak, and then eliminate the sound that the wind of the high blast of high wind speed sends because of abnormal vibrations directly through fin during vaporizer 4.
Wherein, wind can be derived in one direction by flow guide bar 3 with a guide face, alternatively, it is also possible to two water conservancy diversion
Wind is derived by face along both direction, and specifically, as shown in Figure 2 and Figure 4, flow guide bar 3 includes first near the surface of impeller 22 leads
The air-out tangent with impeller 22 edge can be divided into by stream interface 31 and the second guide face 32, the first guide face 31 and the second guide face 32
Two parts are derived.Compare with a guide face wind-guiding, can be the portion of blowout at the air outlet 23 of spiral case 21 with two guide faces
Divide wind to derive along both direction, wind speed and the static pressure of wind can be reduced to greatest extent, wind can be more after flow guide bar 3 water conservancy diversion
Uniformly, thus when through vaporizer 4 fin will not produce abnormal sound, it is to avoid make certain side with a guide face wind-guiding
To wind excessively concentrate, can be uneven when by vaporizer 4.
Further, the first guide face 31 of flow guide bar 3 connect with the second guide face 32 composition cross sectional shape not only
One, the such as first guide face 31 and the second guide face 32 can connect in u shape face, in addition, as shown in Figure 2 and Figure 4, the first water conservancy diversion
Face 31 and the second guide face 32 can also connect in v shape face.Compare two guide faces and connect in u shape face, two guide faces connect in v shape
Face can make the part wind energy that the air outlet 23 of spiral case 21 blows out enough along the first guide face 31, the second guide face 32 obliquely upward
Accurately derive with obliquely downward.
In order to preferably eliminate the abnormal sound that vaporizer 4 fin sends, as shown in Figure 2 and Figure 4, preferably by the first water conservancy diversion
The phase connection of face 31 and the second guide face 32 is located on the air-out path tangent with impeller 22 edge, such wind speed this portion quickly
Point wind can by flow guide bar 3 be divided into two parts and along two guide faces obliquely upward, obliquely downward derive, thus, it is possible to reduce this
The wind speed of part wind and static pressure, thus the abnormal sound that vaporizer 4 fin sends can preferably be eliminated.
In order to by the air-out with impeller 22 edge direction tangential along the first guide face 31 and the second guide face 32 two
Direction is equably derived, as shown in Figure 2 and Figure 4, preferably by the angle bisection of the first guide face 31 and the angle of the second guide face 32
Line is along the air-out path setting tangent with impeller 22 edge.So, the first guide face 31, the second guide face 32 with along impeller 22 side
Angle along direction tangential will be equal, and the air-out along this tangent line will be uniform with obliquely downward obliquely upward along two guide faces
Ground is derived, and that is, the air quantity of wind that both direction derives, wind speed are equal or approximately equal.
In order to can make wind evenly in vaporizer 4 while eliminating vaporizer 4 fin abnormal sound again,
As shown in Figure 2 and Figure 4, the angle of the first guide face 31 and the second guide face 32 is preferably 30 °～120 °.If two guide faces
Angle too small, flow guide bar 3 to the direction of the air-out of impeller 22 edge direction tangential change less, then with impeller 22 edge
After two guide faces through flow guide bar 3 for the air-out of direction tangential are derived, wind speed changes also less, so elimination vaporizer 4 with static pressure
The effect of the abnormal sound of fin is just not so good；If two guide face angles are excessive, the portion of air outlet 23 blowout of spiral case 21
Point wind after two guide faces of flow guide bar 3 are derived, reach vaporizer 4 upper right side, lower left wind less it is impossible to evaporation
This air quantity at two of device 4 is effectively supplemented, thus being unfavorable for wind evenly in vaporizer 4.Therefore, the first water conservancy diversion
When the angle of face 31 and the second guide face 32 is 30 °～120 °, ensure that while elimination vaporizer 4 fin abnormal sound again
Wind can be made evenly in vaporizer 4.
In order to be further able to while eliminating vaporizer 4 fin abnormal sound can make wind evenly into evaporation again
In device 4, as shown in Figure 2 and Figure 4, the first guide face 31 and the second guide face 32 be preferably 30 along the width in water conservancy diversion direction～
50mm.If two guide faces are too small along the width in water conservancy diversion direction, the air-out with impeller 22 edge direction tangential is easy for bypassing
Flow guide bar 3 and be directly blown on vaporizer 4, the effect so eliminating the abnormal sound of vaporizer 4 fin is just not so good；If two
Individual guide face is excessive along the width in water conservancy diversion direction, so the wind of air outlet 23 blowout of spiral case 21 will be played with flow guide bar 3
Barrier effect, vaporizer 4 position relative with flow guide bar 3 will air intake less, vaporizer 4 enter wind will be uneven.Cause
This, the first guide face 31 and the second guide face 32 along the width in water conservancy diversion direction be 30～50mm when, ensure that elimination vaporizer 4
Wind can be made evenly in vaporizer 4 while fin abnormal sound again.
Wherein, the structure type of flow guide bar 3 is not unique, and such as flow guide bar 3 can be the strip bulk having two guide faces
The v shape welded plate that structure or two wind deflectors weld together, in addition, as shown in figure 4, flow guide bar 3 can also be v
Shape bending plate.Compare the strip block structure having two guide faces, when flow guide bar 3 is v shape bending plate, its quality is lighter, permissible
Mitigate the weight of air-cooled ducted air conditioner；Compare v shape welded plate, when flow guide bar 3 is v shape bending plate, its manufacturing process is simpler, manufacturing cost
Low, and toughness is higher.Flow guide bar 3 can be made up of steel it is also possible to be made of plastics, and here is not especially limited.
Flow guide bar 3 two ends can be non-dismountable connection with the connected mode of the air outlet 23 of spiral case 21, such as welding, riveting
Connect, in addition, as shown in figure 4, flow guide bar 3 two ends can also be detachably to connect with the connected mode of the air outlet 23 of spiral case 21
Connect, such as mode connects for screw, bolt connection etc..Compare non-dismountable connection, be detachably connected and not only make flow guide bar 3 easy for installation,
And when it damages, it is easy to its replacing.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by described scope of the claims.
