The present invention proposes a kind of cabinet air-conditioner.
In embodiments of the present invention, as shown in Figure 1 to Figure 3, cabinet air-conditioner includes casing and is installed on institute
Stating the noise reduction components 10 in casing, described noise reduction components 10 has an airtight cavity 100, and, institute
State and on noise reduction components 10, offer the through hole 101 that multiple and described cavity 100 connects.
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 described noise reduction components 10 is square setting.The cavity 100 of described noise reduction components 10
Can be enclosed by six wallboards and be formed, it is also possible to be that five wallboards enclose formation and one have a uncovered chamber,
Then by any one inwall of casing, the opening end of described chamber is blocked, to form described cavity 100
(namely the wallboard of noise reduction components 10 forms a part for casing inner wall).It can in addition contain be by one
Wallboard respectively corresponding with the top board of casing, chassis and biside plate connect, thus by the top board of cabinet air-conditioner,
Chassis, backboard, both sides and this wallboard enclose the described cavity 100 of formation.The most described noise reduction components 10
One of described panel, backboard, side plate, top board or chassis can be installed on.It can also be described noise reduction group
The wall portion of part 10 forms a part for described casing inner wall.
The through hole 101 offered on noise reduction components 10 connects with described cavity 100, when the noise in cabinet-type air conditioner leads to
Crossing this through hole 101 and enter in cavity 100, the sound wave of noise causes shaking of cavity 100 room air molecule
Dynamic, owing to air self has viscosity resistance, in addition to air molecule self phase mutual friction, air molecule
Also with noise reduction components 10 inner surface friction so that the acoustic energy of sound wave gradates as frictional heat energy, thus reaches
To noise reduction.
Technical scheme, by arranging a noise reduction components 10 at the inwall of cabinet air-conditioner, makes noise lead to
The through hole 101 crossing noise reduction components 10 enters in cavity 100, and then air molecule in drive cavity 100
Vibration, air molecule vibration in cavity 100 and phase mutual friction, it is eventually converted into heat energy, in this mistake
Cheng Zhong, is eventually converted into acoustic energy heat energy, thus reaches noise reduction.
With reference to Fig. 3, the position of through hole 101 is relevant with noise reduction, and through hole 101 receives noise and is easier to then
Noise reduction is more preferably.In one embodiment, noise reduction components 10 includes facing described casing a inwall and with
The base plate 11 that described inwall connects, and the noise reducing plate 12 relative with described base plate 11, described noise reducing plate
Multiple described through hole 101 it is provided with on 12.Owing to this noise reducing plate 12 maximum area can receive cabinet air-conditioner
The noise sent, so, through hole 101 is arranged on this noise reducing plate 12 and more noise can be made direct
Entering in cavity 100 by through hole 101, noise reduction is more preferably.
With continued reference to Fig. 3, although the noise within cabinet air-conditioner outwards can be spread out of by all directions, but
Clearly as the structure that arranges of close panel in cabinet air-conditioner is more, noise before panel spreads out of,
Being hindered by multiple structures, final noise is the least.And backboard area is relatively big, therefore, by described fall
Assembly 10 of making an uproar is installed on the backboard of cabinet air-conditioner, and noise reduction components 10 can be made to contact the area in source of making an uproar more greatly,
Noise reduction is more preferably.
With reference to Fig. 1 and Fig. 3, in one embodiment, noise reduction components 10 also include being positioned at described base plate 11 with
Coaming plate 13 between described noise reducing plate 12, described coaming plate 13, base plate 11 and described noise reducing plate 12 are common
Enclose the described cavity 100 of formation, described coaming plate 13 offers multiple described through hole 101.Noise reducing plate 12
The noise of noise reduction components 10 can be will be close to, or the noise radiated towards noise reducing plate 12 well absorbs,
But for the noise sent by the structure away from noise reduction components 10, noise reducing plate 12 is difficult to absorb, therefore,
Coaming plate is also offered through hole 101, it is possible at multi-direction absorption noise, strengthen noise reduction further.
Due to the restriction of cabinet air-conditioner self structure, the degree of depth of cavity 100, namely noise reducing plate 12 is in interior
Spacing between wall is unsuitable excessive, otherwise other structure in cabinet-type air conditioner can be caused interference.In the present embodiment,
Described noise reducing plate 12 is more than 0 less than or equal to 10mm with the spacing of described base plate 11.Certainly, this spacing is also
Being difficult to too small, otherwise noise reduction is the best, and the spacing of noise reducing plate 12 and described inwall is at 5mm to 8mm
For preferred embodiment.
Except the degree of depth of cavity 100, the aperture of through hole 101 should also be as suitably, and aperture is crossed conference and caused sky
In chamber 100, air molecule vibrating effect is the best, and noise reduction is the most bad.In one embodiment, described logical
Hole 101 diameter D is less than or equal to 3mm more than 0.If it addition, the aperture of through hole 101 is too small, sound
Sound wave be difficult to enter in cavity 100, so, noise reduction components 10 is poor to the assimilation effect of sound, institute
With, the aperture D of through hole 101 is better embodiment at 1.5mm to 2.5mm.
With reference to Fig. 6, above-mentioned through hole 101 is respectively provided with two ports, and one of them is for being positioned at noise reduction components 10
The external port of outer surface, another through hole 101 is positioned at the inner port of noise reduction components 10 inner surface, in order to make fall
Make an uproar assembly 10 to the assimilation effect of noise more preferably, in the present embodiment, the external port of described through hole 101 is (remote
Single port from described inwall) the export-oriented setting in flaring.
With reference to Fig. 4 and Fig. 5, in order to strengthen the noise reduction of noise reduction components 10 further, in the present embodiment
In, it is provided with concaveconvex structure 14 in described cavity 100.After noise is entered vestibule by through hole 101, one
Air molecule vibration in aspect cavity 100, is converted into acoustic energy heat energy, thus reaches noise reduction；
On the other hand, sound wave, under the effect of concaveconvex structure 14, happens over and over again reflection, and acoustic energy constantly reduces,
Thus reach noise reduction.
With reference to Fig. 5 and Fig. 7, in a upper embodiment, concaveconvex structure 14 can be regular, it is also possible to is
Irregular, in order to strengthen the noise reduction of noise reduction components 10 further, in the present embodiment, described recessed
Male structure 14 is arranged in labyrinth.Arrange in cavity and form complicated passage in so-called labyrinth, i.e. concaveconvex structure,
Noise can be to multiple directions conduct acoustic waves after entering this passage, and such as, sound wave is punished at first node
It is that three directions are propagated, is divided into both direction to propagate at second node, the 3rd direction is divided again
Propagating for both direction, so circulate, the energy of final sound wave is progressively consumed.So referring in particular to Fig. 7,
After noise is entered cavity 100 by through hole 101, noise is propagated in multiple directions, in each direction of propagation
On, the sound wave of noise is under the effect of concaveconvex structure, and multiple reflections, the energy of sound wave is converted into the most at last
Heat energy.
In one embodiment, with reference to Fig. 5, in order to further improve the noise reduction of noise reduction components 10,
The material of described concaveconvex structure 14 is polyester fiber.Polyester fiber self has more gap, when noise by
When this gap enters, the sound wave of noise is at the internal reciprocating collision of polyester fiber, owing to gap is longer, and relatively
In disorder, noise gradually uses up energy in this process, thus serves the effect of sound-absorbing.
Cabinet air-conditioner is according to the model of product, and its noise level is the most variant.For the air-conditioning that noise is bigger
For cabinet-type air conditioner, its noise reduction demand is higher；For the cabinet air-conditioner that noise is less, its noise reduction demand is relatively
Low.Here, practical situation can be passed through, in regulation cabinet air-conditioner, the quantity of noise reduction components, can meet
The demand of different cabinet-type air conditioners.In one embodiment, with continued reference to Fig. 1, the inwall of described cabinet air-conditioner is provided with
Mounting structure (such as, the inwall at cabinet air-conditioner arranges clasp, arranges catching groove on noise reduction components, and two
Person is coordinated by clasp and catching groove and is realized removably connecting；It can also be the inwall setting at cabinet air-conditioner
Trapezoidal projection, arranges dovetail groove on noise reduction components, and the two is real by the cooperation of trapezoidal projection and dovetail groove
Now removably connect), described noise reduction components 10 can by the inwall of described mounting structure with described cabinet air-conditioner
Dismounting connects.So, can fill an appropriate number of inside cabinet air-conditioner according to the model of cabinet air-conditioner
Noise reduction components 10.Such as, in the cabinet air-conditioner that noise is bigger, 3 noise reduction components 10 are assembled, at noise relatively
In little cabinet air-conditioner, 1 noise reduction components 10 of assembling, can reduce cost.
