Condition understands the concrete meaning of above-mentioned term in the present invention.
The outlet air according to an embodiment of the present invention for air-conditioner outdoor unit (not shown go out) is described in detail with reference to the accompanying drawings
Mesh enclosure 100.It should be noted that air outlet mesh 100 is equipped with multiple air outlets 16.Air-conditioner outdoor unit at work, (scheme by fan
It is not shown) rotate the front side that the air of 100 rear side of air outlet mesh is blowed to air outlet mesh 100 by air outlet 16.
As shown in Fig. 1-Figure 10, the air outlet mesh 100 according to an embodiment of the present invention for air-conditioner outdoor unit, comprising: net
Cover main body 10 and silencing apparatus.Specifically, silencing apparatus is connected to the rear side of mesh enclosure main body 10 to lead to air outlet mesh 100
It is dynamic to eliminate the noise.The air-flow with noise that fan generates first passes through silencing means noise reduction when flowing through air outlet mesh 100, then by going out
Air port 16 is blown out.The wind noise of air outlet mesh 100 is reduced as a result, improves the quality of outlet air sound.
Air outlet mesh 100 according to an embodiment of the present invention for air-conditioner outdoor unit, passes through the rear side in mesh enclosure main body 10
Silencing apparatus is set and significantly reduces wind noise compared to traditional air outlet mesh, improves the sound quality of noise, significantly
Ground improves the performance of product, improves the satisfaction of user.
As shown in Figure 1, Figure 3, according to some embodiments of the present invention, silencing apparatus includes the first sound attenuation assembly 20a.Specifically
The center on ground, mesh enclosure main body 10 has recessed portion 11 recessed from the front to the back, and the first sound attenuation assembly 20a is located in recessed portion 11.
That is, the center of mesh enclosure main body 10 is recessed to accommodate the first noise reduction component 20a to front side.Thus it is convenient for the first noise elimination group
Part 20a is mounted in mesh enclosure main body 10.For example, mesh enclosure main body 10 and recessed portion 11 can be formed as round, circular depression
The center of circle be overlapped with the center of circle of circular net cover main body.
Further, as shown in Figure 3, Figure 4, the first sound attenuation assembly 20a includes: noise elimination disk 21 and Perforated decking 22, porous
Cover board 22 is located at the rear side of noise elimination disk 21 and is fixed at recessed portion 11.As shown in fig. 7, having on Perforated decking 22 multiple along it
The first through hole 221 of thickness direction perforation.It is understood that particular determination is not done for the distribution mode of first through hole 221,
For example, in the example shown in fig. 7, first through hole 221 can be evenly distributed on Perforated decking 22.
In some preferred examples of the invention, the thickness of Perforated decking 22 can be 0.3-2.0mm, first through hole
221 radial dimension is 0.5-1.5mm, and punching rate of the first through hole 221 on Perforated decking 22 is 1%-30%.Here, it wears
Porosity refers to the percentage of the summation of the area of all first through hole 221 on Perforated decking 22 and the gross area of Perforated decking 22
Than.
It should be noted that noise elimination disk 21 can be made of sound-absorbing porous material.The noise-cancelling theory of first sound attenuation assembly 20a
Be: when air-conditioner outdoor unit works, the sound wave that fan rotation generates enters noise elimination disk by the first through hole 221 on Perforated decking 22
In 21, part sound can generate friction in the hole of sound-absorbing material, and then be converted to thermal energy, finally dissipate, thus reduce
The acoustic wave energy of wind noise out reduces wind noise value, improves the outlet air sound quality of air outlet mesh 100.To further increase
The noise elimination effect of first sound attenuation assembly 20a, Perforated decking 22 can be by stainless steel materials or other metals by antirust treatment
Plate is made.
In example as shown in Figure 3, Perforated decking 22 connect with mesh enclosure main body 10 and noise elimination disk 21 is mounted on recess
Between portion's roof 17 and Perforated decking 22.Specifically, noise elimination disk 21 can be located in recessed portion 11, such as noise elimination disk 21 is embedded in
In recessed portion 11.In such as Fig. 5-example shown in fig. 6, there are multiple center line sides along recessed portion 11 on recessed portion side wall 16
To the installation base 13 of extension, there are the multiple escape groove 211 for avoiding multiple installation bases 13 on the periphery wall of noise elimination disk 21.Dress
Timing, the installation base 13 at recessed portion 11 cooperate in the escape groove 211 of noise elimination disk 21.On Perforated decking 22 at neighboring edge
With with the one-to-one multiple mounting holes 222 of installation base 13.Perforated decking 22 and mesh enclosure main body 10 are by passing through mounting hole
222 and installation base 13 screw 30 connect.The first sound attenuation assembly 20a can be made to connect more firm with mesh enclosure main body 10 as a result,
Gu.
Further, as shown in Figure 3, Figure 4, in some embodiment of the invention, silencing apparatus includes the second of annular
Sound attenuation assembly 20b.For convenient for the second sound attenuation assembly 20b to be mounted in mesh enclosure main body 10, the outer edge of mesh enclosure main body 10 is backward
Extend the flange 14 of annular, the second sound attenuation assembly 20b is located on the inner surface of flange 14.
In example as shown in Figure 2, Figure 4 shows, the second sound attenuation assembly 20b includes: porous ring 23 and noise elimination ring 24.Specifically
Ground has multiple second through-holes 231 penetrated through along its thickness direction in porous ring 23.Noise elimination ring 24 is located at porous ring 23 and flange
Between 14.In example as shown in Figure 5, Figure 8, on the inner surface of flange 14 between compartment of terrain be distributed with it is multiple along mesh enclosure main body 10
The convex ribs 15 that extend of axial direction, the lateral wall of noise elimination ring 24 is equipped with and the one-to-one groove 241 of multiple convex ribs 15.By
Noise elimination ring 24, is connected on the inner surface of flange 14 by this in which can be convenient.Further, as shown in Fig. 2, Fig. 8, porous ring 23
Back edge extend radially outwardly out the flange 232 of annular, flange 232 and flange 14 pass through screw 30 and connect, noise elimination ring 24
It is clipped between porous ring 23 and flange 14.The second sound attenuation assembly 20b can be fixed on mesh enclosure main body 10 strongerly as a result,
On.
It is understood that the distribution mode of the second through-hole 231 is not done it is specifically limited, for example, as shown in Figure 9
In example, the second sets of vias of multiple row is distributed in compartment of terrain in the circumferential direction of porous ring 23, and the second sets of vias of each column includes more
The second through-hole 231 that a axial direction compartment of terrain along the porous ring 23 is distributed.
In some preferred examples of the invention, the radial thickness of porous ring 23 is 0.3-2.0mm, the second through-hole 231
Punching rate in porous ring 23 is 1%-30%, and the radial dimension of the second through-hole 231 is 0.5-1.5mm.Herein, punching rate is
Refer to the percentage of the area of the summation of the area of all second through-holes 231 in porous ring 23 and the side wall of porous ring 23.
It should be noted that noise elimination ring 24 can be made of sound-absorbing porous material.Second sound attenuation assembly 20b and first eliminates the noise
The noise-cancelling theory of component 20a is identical, it may be assumed that when air-conditioner outdoor unit works, the sound wave that fan rotation generates passes through in porous ring 23
Second through-hole 231 enters in noise elimination ring 24, and part sound can generate friction in the hole of sound-absorbing material, and then be converted to thermal energy,
It finally dissipates, thus reduces out the acoustic wave energy of wind noise, reduce wind noise value, improve air outlet mesh 100
Outlet air sound quality.For the noise elimination effect for further increasing the second sound attenuation assembly 20b, porous ring 23 can be by stainless steel materials or other
It is made by the sheet metal of antirust treatment.
