The utility model proposes a kind of cabinet air-conditioner.
In this utility model embodiment, as shown in Figures 1 to 4, cabinet air-conditioner includes casing and noise reduction
Assembly 10, described noise reduction components 10 includes the housing 11 with a closed cavity 110, described housing 11
Including the inwall facing described cabinet air-conditioner and the base plate 111 being connected with described inwall, and with the described end
The first noise reducing plate 112 that plate 111 is relative, described first noise reducing plate 112 offers and described cavity 110
First through hole 101 of connection；Described noise reduction components 10 also includes that being intercepted by described cavity 110 is two chambers
And second noise reducing plate 12 relative with described first noise reducing plate 112, described second noise reducing plate 12 offers
By the second through hole 102 of described two chamber.
Concrete, the casing of cabinet air-conditioner includes panel, backboard, connection panel and the side plate of backboard, top
Plate and chassis.As a example by housing 11 is square setting.The cavity 110 of described housing 11 can be by six walls
Plate encloses formation, it is also possible to is that five wallboards enclose formation and one have a uncovered chamber, then passes through machine
The opening end of described chamber is blocked by any one inwall of shell, to form described cavity 110.It can in addition contain
It is to be connected respectively by top board, chassis and the biside plate of a wallboard with casing, thus forms described sky
Chamber 110.The most described housing 11 can be installed on described panel, backboard, side plate, top board or chassis
One of.It can also be the wallboard of described housing 11 part that forms described casing inner wall.
Cavity 110 is divided into the first chamber 110a and the second chamber 110b by the second noise reducing plate 12, and first
Noise reducing plate 112 and the second noise reducing plate 12 form two wallboards of the first chamber 110a, the second noise reducing plate 12
With two wallboards that backboard forms the second chamber 110b.The first through hole 101 offered on first noise reducing plate 112
Connecting with the first chamber 110a, the second through hole 102 that the second noise reducing plate 12 is offered is by the first chamber 110a
Connect with the second chamber 110b.
With reference to Fig. 3 and Fig. 4, through two-stage noise reduction after the noise entrance housing 11 in cabinet-type air conditioner: first, when
Noise in cabinet-type air conditioner is entered in the first chamber 110a by the first through hole 101, and the sound wave of noise causes first
The vibration of air molecule in chamber 110a, owing to air self has viscosity resistance, except air molecule certainly
Outside body phase mutual friction, air molecule also rubs with the first chamber 110a inner surface so that the acoustic energy quilt of sound wave
Consuming, noise is lowered, thus completes one-level noise reduction.After one-level noise reduction completes, remaining noise is by
One chamber 110a enters in the second chamber 110b through the second through hole 102, and noise is at the second chamber 110b
The most again cause the vibration of air molecule in the second chamber 110b, make acoustic energy again be consumed, from completing two
Level noise reduction.
The technical solution of the utility model, by arranging a noise reduction components 10 in cabinet air-conditioner, makes noise lead to
Cross the first through hole 101 of noise reduction components 10 and the second through hole 102 and successively enter two chambers, and then drive
The vibration of two chamber air molecules, air molecule vibration in two cavitys 110 and phase mutual friction,
It is converted into heat energy eventually, it is achieved two grades of noise reductions, is greatly improved noise reduction.
With reference to Fig. 1, although the noise within cabinet air-conditioner outwards can be spread out of by all directions, but aobvious
So, the structure arranged due to the close panel in cabinet air-conditioner is more, and noise, before panel spreads out of, is subject to
The obstruction of multiple structures, final noise is the least.And backboard area is relatively big, therefore, by described noise reduction group
Part 10 is installed on the backboard of cabinet air-conditioner, noise reduction components 10 can be made to contact the area in source of making an uproar more greatly, fall
Make an uproar better.
With continued reference to Fig. 3 and Fig. 4, although noise can successively enter the first chamber 110a and the second chamber
110b, but play the still first chamber 110a of main Noise Reduction.Noise enter the first chamber 110a and
After one-level noise reduction, can filter most noise, remaining noise is filtered by the second chamber 110b.
Here, consider that the aperture of the first through hole 101 is crossed conference and caused air molecule vibrating effect in cavity 110
The best, noise reduction is the most bad.To this end, in one embodiment, the aperture d of described first through hole 1011
More than 0 less than or equal to 3mm.If it addition, the aperture of through hole is too small, the sound wave of sound is difficult to enter
In one chamber 110a, so, noise reduction components 10 is poor to the assimilation effect of sound, so, the first through hole
Aperture be better embodiment at 1.5mm to 2.5mm.Equally, the aperture d of the second through hole 1022
Unsuitable excessive, aperture is crossed conference and is reduced the vibrating effect of air molecule in the first chamber 110a, implements one
In example, the aperture d of the second through hole 1022More than 0 less than or equal to 2mm, certainly, the second through hole 102
Aperture d2Also unsuitable too small, otherwise poor to the assimilation effect of noise, the aperture d of the second through hole 1022?
1mm to 1.5mm is better embodiment.It should be noted that the aperture d of described first through hole 1011
It is greater than the aperture d of described second through hole 1022.This is because, after the first chamber 110a filters,
Remaining noise is relatively small, the aperture d of the second through hole 1022There is no need to be made relatively big, be made bigger
The vibrating effect of air in the first chamber 110a can be affected on the contrary.
In addition to the aperture of the first through hole 101 and the second through hole 102 is restricted, the first chamber 110a's is deep
The degree of depth of degree and the second chamber 110b is the most restricted.With reference to the test data of Tables 1 and 2, (L1Position the
The degree of depth of one chamber 110a, L2The degree of depth of position the second chamber 110b).
Table 1, the degree of depth of the first chamber 110a of noise reduction components 10, the degree of depth of the second chamber 110b and fall
The relation table of the amount of making an uproar
Table 2, the degree of depth of the first chamber 110a of noise reduction components 10, the degree of depth of the second chamber 110b and fall
The relation table of the amount of making an uproar
As can be seen here, L is worked as2/L1During more than 3, the noise reduction of noise reduction components 10 is obviously improved.
Although L2/L1The noise reduction of noise reduction components 10 can be significantly improved during more than 3, but due to sky
Adjust the restriction of cabinet-type air conditioner self structure, d2And d1Own dimensions is also conditional.With reference to Fig. 3, the first chamber
The degree of depth of room 110a and the second chamber 110b is all unsuitable excessive, otherwise can make other structure in cabinet air-conditioner
Become interfere, such as with blower fan interfere or with heat exchanger interference etc..In the present embodiment, the first chamber
The degree of depth of 110a is less than or equal to 10mm more than 0.Certainly, this spacing is also unsuitable too small, otherwise noise reduction effect
Fruit is the best, and noise reducing plate is preferred embodiment with the spacing of described inwall at 5mm to 8mm.Equally,
The degree of depth of two chambers is the most restricted, and the degree of depth of the second chamber 110b is less than or equal to 50mm more than 10, preferably
15mm to 25mm.
With reference to Fig. 5, above-mentioned first through hole 101 is respectively provided with two ports, and one of them is for being positioned at the first noise reduction
First port of the outer surface of plate 112, another port is positioned at the inner surface of the first noise reducing plate 112, in order to
Make the first noise reducing plate 112 to the assimilation effect of noise more preferably, in the present embodiment, described first through hole 101
External port (the first port) arrange in outside flaring.Equally, above-mentioned second through hole 102 is respectively provided with two
Individual port, one of them is the second port near the first noise reducing plate 112, in order to make the second noise reducing plate 12
To the assimilation effect of noise more preferably, the second port of described second through hole 102 is from described first noise reducing plate 112
In tapered setting on the bearing of trend of described second noise reducing plate 12.
With reference to Fig. 3 and Fig. 4, after noise is entered the first chamber 110a by the first through hole 101, can be first
Chamber 110a internal loss part energy, then enters in the second chamber 110b.In one embodiment, for
Make the noise reduction of described noise reduction components 10 more preferably, described first through hole 101 and described second through hole 102
In setting of staggering (the first noise reducing plate 112 towards on the direction of the second noise reducing plate 12 in setting of staggering),
Directly to be entered by the second through hole 102 after avoiding noise directly to have the first through hole 101 to enter the first chamber 110a
Enter the second chamber 110b.So, after noise enters the first chamber 110a, noise will not easily enter
In second through hole 102.That is, the second through hole 102 enters the second chamber 110b for noise and brings obstruction, makes an uproar
Sound can lose relatively multi-energy in the first chamber 110a, and then makes noise reduction more preferably.
With continued reference to Fig. 4, the first noise reducing plate 112 can will be close to the noise of noise reduction components 10, or court
Noise to the first noise reducing plate 112 radiation well absorbs, but for by the knot away from noise reduction components 10
The noise that structure sends, the first noise reducing plate 112 is difficult to absorb.Given this situation is planted, in the present embodiment, institute
State noise reduction components 10 to include connecting described first noise reducing plate 112 and described inwall and forming described cavity 110
Coaming plate 113, described coaming plate 113 is provided with third through-hole (not showing in figure), so the most permissible
At multi-direction absorption noise, strengthen noise reduction further.
The foregoing is only preferred embodiment of the present utility model, not thereby limit of the present utility model specially
