Embodiment
As shown in Fig. 6 to 8, the present invention proposes a kind of anti-noise guard of uttering long and high-pitched sounds, and the guard 1 includes several ribs 11.
As shown in Fig. 9,10, air-flow is flowed into from the inlet side of guard 1, and the air side that backward guard 1 is separated by rib 11 is flowed out, guard
1 air side is provided with wind deflector 2, and wind deflector 2 can be each along its axis of rotation to any operating position, each rib 11 and wind deflector 2
Operating position is non-coplanar, to change the direction of gas separation flowing, avoids the air-flow after separation and the frontal impact of wind deflector 2,
Prevent the significant vortex noise of uttering long and high-pitched sounds of generation.
The form of guard 1 have it is a variety of, can include along at least two different directions arrange several ribs 11, in order to reduce
The complexity of guard inner rip arrangement, processing cost is reduced, as shown in Fig. 6 to 8, in a preferred embodiment of the invention, net
Cover 1 is made up of several ribs 11 along two kinds of different directions arrangements, and interconnection is integrated adjacent rib 11 each other,
Rib 11 in guard is divided into first direction rib 111 and second direction rib 112, first direction rib 111 and by direction
The angle α scope of two direction ribs 112 is 45 ° ~ 90 °, and the angle α of first direction rib 111 and second direction rib 112 is preferred
For 90 °, to save material cost.Adjacent multiple first direction ribs 111 and the interconnection back wall of second direction rib 112 into
One circle formed wind mesh 113, and the area S scopes for crossing wind mesh 113 are 250mm2~450mm2, to avoid human hand from stretching into or larger
Foreign matter enter in air channel, wherein the area S for crossing wind mesh 113 is preferably 400mm2.As shown in Figure 10,11, it is being preferable to carry out
In example, compared to net cover structure more of the prior art, the section structure of guard 1 of the invention along air-out direction greatly simplifies, from
And reduce on the in-plane direction of wind deflector 2 because of air-flow low-pressure area caused by guard 1, change air-flow separation and occur direction, to avoid
It is coplanar with wind deflector 2, so as to block noise production path of uttering long and high-pitched sounds.
Certainly, as shown in Figure 12 to 16, guard of the invention can also have other alternate embodiments, and guard 1 also includes two
Root mounting bar 12, mounting bar 12 is laterally set, with wind deflector 2 and the shaft parallel of wind deflector 2.Rib 11 in guard 1 arranges
Between two mounting bars 12, except mounting bar 12 is remaining 11 equal non-transverse of rib laterally outside in guard, rib can be
Lengthways of rod, oblique rib, rake interaction rib etc., the rib 11 and 2 each operating position of wind deflector between two mounting bars 12 are equal
It is non-coplanar, but the situation coplanar with mounting bar 12 occurs in wind deflector 2 in rotation process, therefore must be incited somebody to action during the installation of guard 1
Mounting bar 12 is embedded to be placed, and to avoid air-flow blow-through mounting bar 12, generation, which is uttered long and high-pitched sounds, is vortexed noise.
As shown in Fig. 9,10, the invention also provides a kind of air outlet structure with above-mentioned guard, including：Air outlet,
Guard 1 at air outlet, the wind deflector 2 positioned at the air side of guard 1, located at the inlet side of guard 1 sweep air blade 3,
Support 4 at air outlet, wind deflector 2 contribute to change air current flow direction with air blade 3 is swept, and support 4 is used to install
Guard 1, wind deflector 2 and sweep air blade 3.Preferably, the size of guard 1 and the size of air outlet match, and air outlet is provided with
The benefit of guard 1 can be prevented from human hand and stretch into air channel, is also possible to prevent larger foreign matter and enters inside air channel.
In alternative embodiments, as shown in Figure 17,18, in order to avoid the generation for vortex noise of uttering long and high-pitched sounds, the two of air outlet
Set in opposed inner walls it is built-in sink groove 5, the groove of air outlet upper inside walls is not completely shown in wherein Figure 18, guard 1
Two mounting bars 12 are placed in groove 5 during installation, air-flow will not blow-through this two mounting bars 12, uttered long and high-pitched sounds so as to effectively block
It is vortexed the production path of noise.
The invention also provides a kind of air conditioner, including above-mentioned air outlet structure.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
