Within enclosing.
The present invention proposes a kind of air fairing, and with reference to Fig. 2 and Fig. 3, which includes 1 He of rectification block
Air-duct spiral case 2, the tubular wine wheel 10 of air conditioner is equipped in air-duct spiral case 2, which includes constituting air-conditioned wind tunnel
Lower frame 21 and upper side frame 22, air-duct spiral case 2 guide the air-flow that the tubular wine wheel 10 of air conditioner introduces to the air outlet W in air duct
Outflow, rectification block 1 are set on lower frame 21 at air outlet W.
Air-duct spiral case 2 is mounted therein by tubular wine wheel 10, and the inner wall of air-duct spiral case 2 is to tubular wine wheel 10 from external pumping
The air-flow entered is drained (as shown in Fig. 2 air current flow directions F), and most of air-flow, which circulates to air-conditioned wind tunnel air outlet W, to flow
Go out, fraction air-flow is again introduced into the airflow circulating in air-duct spiral case 2 from the vortex tongue around 22 end of upper side frame.Rectification block 1
It is arranged on lower frame 21 at air outlet, i.e., rectification block 1 is arranged on the air-out direction of air conditioner, the rectification block 1
Cross section can be arbitrary shape, such as rectangular, outer convex, concave arc etc..With reference to Fig. 4, which is one,
And the rectification block 1 is set on 21 surface of lower frame and along the continuous strip of entirety of the length direction of the lower frame 21 extension
Shape block；Rectification block 1 is multiple, and the rectification block 1 is set to the both ends of lower frame 21 alongst.
In the present embodiment, go out to be arranged rectification block 1 close to air outlet W by the lower frame 21 in air fairing,
Rectification block 1 is arranged on the air-out direction of air conditioner, to which rectification block 1 blocks air outlet W outlet air section, reduces
The outlet air section of air outlet W, the local lifting flow velocity of eluting gas, uses pneumatic pressure and increases, to which outlet air dynamic pressure is bigger
The airflow reflux static pressure that bigger can be overcome to inhibit gas outside air outlet W to flow back into air outlet W, and then inhibits
There is the technical issues of pulsation surge sound to solve air conditioner in pulsation surge sound.
Further, with reference to Fig. 2 and Fig. 3, the cross section of rectification block 1 is arc, where air-flow flows through rectification block 1
When position, the rectification block 1 of arc keeps air-flow change direction more soft, and the change in flow for blowing out air-flow is more gentle, avoids
There is abnormal sound because blowing out air-flow velocity change dramatically through air outlet.
Preferably, rectification block 1 is inner concave arc surface towards the one side inside air-duct spiral case, i.e. 1 height of rectification block is relatively low
Side towards inside air-duct spiral case 2, be away from each other with air-out direction, the 1 higher-height side of rectification block and air-out direction
Unanimously, to further alleviate the air-flow wind speed generation drastic change for flowing through rectification block 1, further weaken outlet air air-flow because of air-flow stream
Fast change dramatically and there is the intensity of abnormal sound.Optionally, the plane tangent of the inner concave arc surface of rectification block 1 and lower frame, flows through
The air-flow of rectification block 1 can be entered with non-resistance on its inner concave arc surface, to further alleviate the air-flow wind for flowing through rectification block 1
Drastic change occurs for speed, improves the structural stability of air fairing, also reduces the intensity and probability that abnormal sound occurs.
Further, referring to Figures 1 and 2, the angle based on lower frame 21 and upper side frame 22 determines that air conditioner is following at this
Low regime S on frame 21, rectification block 1 are set in the S of the low regime.
Low regime is related to angle formed by the lower frame 21 of air-duct spiral case 1 and upper side frame 22, the more big then low speed of the angle
The range in area is bigger.Specifically, can be by probe velocimetry on lower frame 21, especially the two of 21 length direction of lower frame
End, air-out direction on detection obtain low regime S (gas flow rate is known as low speed less than preset value), rectification block 1 is set to this
In the S of low regime, it is preferable that the coverage area of rectification block 1 is slightly larger than the coverage area of low regime S, to which rectification block 1 is to low
The air-flow of fast area S is raised speed comprehensively, will not be flowed back after being further ensured that all air-flows outflow air outlet W for flowing through low regime S.
Preferably, with reference to Fig. 2, the low regime cross sections S are triangle, inner concave arc surface and 21 phase of lower frame of rectification block 1
The point of contact cut is overlapped with boundary point P of the low regime S far from air outlet W, and the inner concave arc surface of rectification block 1 is overlapped with eccentric arc, should
Eccentric arc is using the center O of the eccentric vortex of air-conditioned wind tunnel as the center of circle, with the center of circle to boundary points of the low regime S far from air outlet
The distance of P is radius institute camber.In addition, under threshold value of the inner concave arc surface far from boundary point P (i.e. inner concave arc surface peak)
The distance of frame 21 is more than the distance of low regime S apogee distances lower frame 21.Using this scheme, rectification block 1 is low to flowing through
The gas flow speeding best results of fast area S, are eliminated or alleviation surge phenomenon is best.
In addition, rectification block is fixedly connected or is integrally formed with lower frame, i.e., rectification block can be directly fixedly connected on
The both ends of lower frame length direction, or rectification stop block structure is directly accomplished on mold, it together will be whole when being molded lower frame
Block injection molding is flowed, convenient for simplifying manufacturing process, improves production efficiency.
The present invention also proposes a kind of air conditioner, which is preferably Split wall-mounted type air conditioner, referring to Fig.1, the air-conditioning
Device includes above-mentioned air fairing and tubular wine wheel 10, and tubular wine wheel 10 is set to the air-duct spiral case of the air fairing
In 2, which introduces the upper side frame 22 and lower frame that external air flow is drained to the air-duct spiral case 2 by air-duct spiral case 2
The 21 air outlet W blowouts constituted.Since this air conditioner uses the above-mentioned whole skills for leading all embodiments of air fairing
Therefore art scheme at least has all advantageous effects caused by the technical solution of above-mentioned air fairing embodiment, herein
No longer repeat one by one.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
In the scope of patent protection that other related technical areas are included in the present invention.
