The function of fixed first panel 10, second panel 20 and silencing cotton 30.
Fig. 2 shows the schematic cross-sectional view of the frame bar of the noise-reducing structure of Fig. 1；Fig. 3 shows the side of the noise-reducing structure of Fig. 1
Structural representation when moulding is assembled with silencing cotton 30.As shown in Figure 1, Figure 2 and Figure 3, frame bar 50 includes：For being oppositely arranged
Side wall 51, second sidewall 52 and the bottom wall 53 being connected between the first side wall 51 and second sidewall 52.First panel 10 with
The first side wall 51 is fitted, and second panel 20 is fitted with second sidewall 52.The first panel 10 and second fitted with the first side wall 51
The second panel 20 of the laminating of side wall 52 and the bottom wall 53 being connected between the first side wall 51 and second sidewall 52 form silencing cavity,
Can play a part of to cut down intensity of acoustic wave to a certain extent.Silencing cotton 30 is set in this silencing cavity and foaming layer 40 is notable
Enhance the erasure effect of noise-reducing structure.
As shown in Fig. 2 in the frame bar 50 of the present embodiment, boss 54, silencing cotton 30, are provided with the first side wall 51
First receiving space is formed between side wall 51 and boss 54, first panel 10 is arranged in first receiving space and is connected to convex
On platform 54.Holding piece 55 is provided with second sidewall 52, is formed between second sidewall 52 and holding piece 55 and is accommodated second panel 20
The second receiving space.During installation, second panel 20 is arranged between second sidewall 52 and holding piece 55 and is formed
The second receiving space in.First panel 10 is connected on boss 54 again, and is clamped in first panel 10 with silencing cotton 30
In the first receiving space formed between silencing cotton 30, the first side wall 51 and boss 54.The second face finally is injected into foaming layer 40
In cavity between plate 20 and silencing cotton 30, the assembling for completing noise-reducing structure is fixed.Said structure light weight Stability Analysis of Structures and tool
There is certain intensity, assemble simple and convenient.
In the present embodiment, bloop 11 is circle.Circular bloop 11 has even structure, spy easy to process
Point.Certainly one skilled in the art will appreciate that the shape of bloop 11 is not limited to circle, or rectangle or other are more
Side shape or even irregular figure, the bloop 11 of above-mentioned shape can realize the sound-absorbing effect of the present embodiment, therefore all at this
The protection domain of application.
Fig. 4 shows the schematic diagram of the bloop group arrangement of the noise-reducing structure of Fig. 1.As shown in figure 4, bloop 11 is
Multiple, multiple bloops 11 form multiple bloop groups, and multiple bloop groups form array structure.Multiple bloops 11 are combined into
Bloop group is arranged in array, and sound wave can be made more uniformly to enter noise-reducing structure, increases the erasure effect of noise-reducing structure.
As shown in figure 4, in the present embodiment, bloop group is rectangular.The bloop group of rectangle can make sound wave equably
Into noise-reducing structure, strengthen the erasure effect of noise-reducing structure.Difference according to actual conditions can change the shape of bloop group,
To reach best erasure effect.
As shown in figure 4, in the present embodiment, being correspondingly arranged between adjacent rows bloop group, the bloop being correspondingly arranged
Group is suitable for the relatively low situation of air velocity.
Embodiment two
Fig. 5 shows the signal of the arrangement of the bloop group of the embodiment two according to noise-reducing structure of the present utility model
Figure.Shown in Fig. 5, embodiment two is improved the shape of bloop group, and bloop group is in the shape of the letter V.Bloop group is along sound wave
The direction of transmission is in the shape of the letter V can make sound wave more uniformly enter noise-reducing structure, increase the erasure effect of noise-reducing structure.
The bloop group arranged with different shape can produce different in the working environment of different air quantity and air velocity
Effect, erasure effect can be improved according to the shape that noise level and air velocity are arranged in correspondence with bloop group.For unit
Different air quantity, overbottom pressure, noise reduction foamed board structure type and layout can produce certain influence on erasure effect, every unit have from
The optimization noise reduction layout of body.When unit air quantity is larger, noise-reducing structure, noise reduction knot need to be installed in surface cooler end foaming Board position
The bloop group layout of structure need to be distributed using V-shaped, and shift to install to reduce indoor returning between adjacent rows bloop group
Noise of the wind (or outdoor fresh air) when surface cooler (or being exchanged heat with surface cooler) is blown over.Meanwhile, fan end, air side also needs
Using noise-reducing structure, the bloop group layout of noise-reducing structure is similar to surface cooler end.
As shown in figure 5, in the present embodiment, being shifted to install between adjacent rows bloop group.The bloop for shifting to install
Group is more suitable for air velocity situation higher.
According to another aspect of the present utility model, present invention also provides a kind of fan coil units, Fig. 6 shows basis
The structural representation of the embodiment of fan coil units of the present utility model.According to one embodiment of the present utility model, such as Fig. 6
It is shown, the fan coil units of the present embodiment, including casing and the motor 1 that is arranged in the accommodating chamber of the casing and air channel snail
Shell 2, wherein, casing includes box-like body 3 and noise-reducing structure 4, and the box-like body 3 and noise-reducing structure 4 surround the accommodating chamber,
The noise-reducing structure 4 is above-mentioned noise-reducing structure.
Due to the small volume of fan coil, compact conformation, it is impossible to set up muffler between the internal structure of fan coil,
And noise-reducing structure is set up in the outside of fan coil, especially installing muffler in the exit of air-duct spiral case can increase crushing,
Reduce operating efficiency.Therefore, the fan coil higher for noise, noise-reducing structure is arranged on casing can reduce unit product
Raw noise, does not interfere with the operating efficiency of fan coil again.
According to another aspect of the present utility model, wind is included present invention also provides a kind of wind cabinet-type air conditioner group (not shown)
Machine coil pack, fan coil units are above-mentioned fan coil units.
