Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng It is exemplary for examining the embodiment that accompanying drawing describes, it is intended to be used for explaining this utility model, and it is not intended that to this utility model Restriction.

Describing the refrigerating plant 100 according to this utility model embodiment below with reference to Fig. 1-Fig. 3, refrigerating plant 100 can be Air-conditioner, refrigerator or ice machine etc., be not especially limited here.

Refrigerating plant 100 according to this utility model embodiment, as it is shown in figure 1, include: crust of the device 1, blimp 2, pressure Contracting machine 3 and the first shock-absorbing foot pad 4, blimp 2 is located in crust of the device 1, limits placed cavity 21, on blimp 2 in blimp 2 It is provided with the mouth of pipe 22.Compressor 3 is located in placed cavity 21, and the refrigerant pipe 31 of compressor 3 passes blimp 2 by the mouth of pipe 22, the One shock-absorbing foot pad 4 is connected between blimp 2 and crust of the device 1.

Here, blimp 2 can be connected on the base plate of crust of the device 1 by the first shock-absorbing foot pad 4, and blimp 2 also can lead to Cross the first shock-absorbing foot pad 4 to be connected in the supporting construction on the base plate of crust of the device 1.

It is to say, in refrigerating plant 100, the outside of compressor 3 is cased with blimp 2, by blimp 2 by compressor 3 keep apart with other structures of device.Meanwhile, blimp 2 is connected on crust of the device 1 by the first shock-absorbing foot pad 4, be equivalent to every Sound cover 2 is separated by first other structures of shock-absorbing foot pad 4 and device.So arrange, can by the noise of compressor 3 and vibration with Other structures of device are all kept apart.

From the point of view of in terms of noise control, compressor 3 is the Main Noise Sources in refrigerating plant 100, and compressor 3 will be to surrounding Air sends significant acoustic wave excitation.After sound wave is delivered to blimp 2, it will usually encouraged the vibration of blimp 2 self, And this vibration is transferred in the air ambient outside blimp 2.It should be noted that the acoustic wave excitation vibration of blimp 2 is produced Raw noise is connected in compressor 3 and is propagated directly to the noise of outside, and the acoustic wave excitation of blimp 2 vibrates compared to commonly Material much smaller, therefore use outside blimp 2 and cover on compressor 3, it is possible to compressor 3 is greatly reduced and is transmitted to extraneous ring Sound wave in border.

From the point of view of in terms of vibration control, compressor 3 is also the primary oscillation source of refrigerating plant 100.When compressor 3 be located at every After in sound cover 2, compressor 3 can outwards transmit vibration by blimp 2.It is understood that a part for the first shock-absorbing foot pad 4 Functioning as spring, arrange the first shock-absorbing foot pad 4 between blimp 2 and crust of the device 1, the first shock-absorbing foot pad 4 has one Fixed elasticity, can allow blimp 2 to vibrate in the range of by a small margin, to consume the vibrational energy produced in compressor 3 running.

In a concrete example, as it is shown on figure 3, refrigerating plant 100 is air-conditioner, at the inside of air-conditioner, air-conditioner Be covered with blimp 2 outside compressor, bottom blimp 2, be provided with the first shock-absorbing foot pad 4, this example be compressor 3 noise and Effective application example of isolating technique method.

Refrigerating plant 100 according to this utility model embodiment, by covering on compressor 3 outside blimp 2, blimp 2 It is connected on crust of the device 1 by the first shock-absorbing foot pad 4, compressor 3 is realized insulation against noise and vibration, thus significantly reduces compressor 3 noise sent and vibrations, make that refrigerating plant 100 running noises is low, it is little to vibrate, it is comfortable to use.The program is applied to air-conditioning system In system, when particularly having noise in the domestic air-conditioning system of strict demand, effect is notable.

In certain embodiments, as it is shown in figure 1, refrigerating plant 100 also includes the second shock-absorbing foot pad 5, the second shock-absorbing foot pad 5 It is connected between blimp 2 and compressor 3.

It is to say, in blimp 2, blimp 2 is kept apart with compressor 3 by the second shock-absorbing foot pad 5.So, by In outside blimp 2, blimp 2 is kept apart with crust of the device 1 also by the first shock-absorbing foot pad 4, and therefore, this embodiment is equivalent to Compressor 3 two grades of compound vibration isolation have been carried out.

It is understood that by the geometry of two-stage shock-absorbing foot pad and shore hardness are carried out reasonable disposition, two-stage The vibration isolating effect of shock-absorbing foot pad is far above the scheme of compressor callosity single-stage vibration isolation of the prior art.Thus two-stage damping callosity Setting, it is possible to play good vibration isolating effect, reduce and transmitted to the vibration of crust of the device 1 again by compressor 3 to blimp 2 Rate, restraining device shell 1 vibrates and noise radiation.

In certain embodiments, for avoiding the noise of compressor 3 to spread out of at the gap of the mouth of pipe 22, can be at refrigerant pipe Sealing member 6 is set between 31 and the internal perisporium of the mouth of pipe 22.Sealing member 6 is utilized refrigerant pipe 31 to be come in and gone out the mouth of pipe 22 of blimp 2 Process, sound wave can be avoided to be leaked into external environment at these mouths of pipe 22, thus improve noise reduction further.

Certainly, the scheme of this utility model embodiment is not limited to this, for example, it is possible to arrange close on the internal perisporium of the mouth of pipe 22 Sealing, sealant is wrapped on refrigerant pipe 31.Again for example, it is possible to arrange sealant on the outer surface of refrigerant pipe 31, close Sealing can block in the mouth of pipe 22.

Due to refrigerant pipe 31 high vibration therewith when compressor 3 runs, cause many potential safety hazards, therefore sealing member Or the setting of sealant, can not only avoid sound wave outwards to propagate along the mouth of pipe 22, and can also consume shaking of refrigerant pipe 31 Energy, thus suppress resonance amplitude, the stress level in refrigerant pipe 31 when reducing vibration, it is to avoid pipeline break and cold occurs The situation that matchmaker reveals.

In certain embodiments, blimp 2 is rigid material part, thus reaches good soundproof effect.

If it should be noted that blimp 2 uses rigid material to make, it is clear that the rigidity of blimp 2 is the highest, its quilt The vibration that acoustic wave excitation occurs is the least, thus the sound wave being delivered in external environment also can be the fewest.Therefore, blimp 2 is optional High by surface density, and the highest material of rigidity makes.

In certain embodiments, at least part of internal face of placed cavity 21 is provided with sound-absorbing material layer 23, thus anti- Only there is " reverberation " effect in compressor 3 in airtight cavity.Here, " reverberation " effect refers to sound wave in blimp through repeatedly After reflection and amplification, the effect that sound wave is strengthened.Therefore use sound-absorbing material layer 23, absorbable acoustic wave energy, make sound wave gradually subtract Weak, noise reduces.

Advantageously, as it is shown in figure 1, be equipped with sound-absorbing material layer 23 on whole internal faces of placed cavity 21, thus comprehensive Absorb sound wave, weaken the noise of outwards propagation.

Alternatively, sound-absorbing material layer 23 is porous fiber layer.Certainly, sound-absorbing material layer 23 can also use other materials system Becoming, such as, sound-absorbing material layer 23 can be acoustical cotton etc..

Blimp 2 also can use other structures, such as, in a concrete example, blimp 2 can include three-layered node Structure, the Rotating fields of blimp 2 is respectively acoustical cotton layer, sound insulation flaggy and case layer from inside to outside, case layer be metal level or Plastic-aluminum layer etc..

The most such as, in another specific example, blimp 2 includes rubber layer and spongy layer, uses Double-layer sound-insulation layer, energy Realize the effect of vibration and noise reduction of multiband.

In certain embodiments, as in figure 2 it is shown, refrigerating plant 100 also include dividing plate 6, dividing plate 6 be located in placed cavity 21 with Placed cavity 21 is separated into multiple points of chambeies 211, and compressor 3 is located in one of them point of chamber 211.So, point chamber having more is utilized 211, acoustic wave energy can be consumed further.

Such as, dividing plate 6 can form annular, and dividing plate 6 circumferentially surrounds compressor 3 and arranges, and dividing plate 6 and compressor 3 are spaced Open, so, the peripheral direction of compressor 3 is equivalent to be provided with double-deck isolation.

Alternatively, dividing plate 6 is provided with the through hole 61 for connecting multiple points of chambeies 211.

It is understood that according to pipeline when expanding suddenly, shrinking or bypass resonant cavity, along the part sound of pipe transmmision Ripple reflects at the abrupt change of cross-section of pipeline, interferes so that the principle that acoustic wave energy declines, thus connected by through hole 61 Point chamber 211 can regard expansion cavity as, when sound wave is propagated in adjacent point chamber 211 by point chamber 211 at compressor 3 place under noise Fall.

Alternatively, in filling sucting sound material part (not shown) in point chamber 211 being not provided with compressor 3, thus one can be entered Step absorbs sound wave, reduces noise.

In certain embodiments, blimp 2 can be provided with for preventing the overheated sending out the hot fan (not shown) of compressor 3 Or radiator (not shown), thus ensure that compressor 3 works under suitable ambient temperature, the work improving compressor can By property.

Such as can set cover opening (not shown) on blimp 2, sending out the hot fan is arranged on opening.The most such as, can be by The pipeline of the circulation low temperature coolant of refrigerating plant 100 is connected on blimp 2, and pipeline may make up radiator.Certainly, radiator is also Other structures can be used, be not especially limited here.

For convenience of understanding, with structure shown in Fig. 1, the internal structure of refrigerating plant 100 in one concrete example is described below.

In this example, refrigerating plant 100 is air-conditioner, and the compressor 3 of air-conditioning (is equivalent to by the second shock-absorbing foot pad 5 One-level vibration isolation) it is arranged among blimp 2, subsidiary two refrigerant pipes of compressor 3 31 are stretched by the mouth of pipe 22 on blimp 2 Going out, be coated with sealing member 7 at the mouth of pipe 22, the inwall of blimp 2 is accompanied with sound-absorbing material layer 23, additionally, blimp 2 is by first Shock-absorbing foot pad 5 (being equivalent to two grades of vibration isolation) is connected with air-conditioning external structure.

This example cardinal principle is to utilize rigid plane to the attenuation of sound wave to realize noise reduction, utilize simultaneously two grades multiple Close vibrating isolation system and realize vibration isolation.Noise control and vibration control two aspect is divided to describe this exemplary scenario advantage below.

In this example, at noise control aspect, blimp 2 selects surface density and the highest material of rigidity, can reduce every The vibration that sound cover 2 is occurred by acoustic wave excitation, makes the sound wave being delivered in external environment less, utilizes the sealing at the mouth of pipe 22 simultaneously Part 7 come in and go out refrigerant pipe 31 mouth of pipe 22 of blimp 2 processes, outside sound wave can be avoided to be leaked at these mouths of pipe 22 Boundary's environment.Additionally, be coated with sound-absorbing material layer 23 in blimp 2, can prevent compressor 3 from airtight cavity, " reverberation " occurring.

In terms of vibration control, owing to compressor 3 is connected with blimp 2 by one-level shock-absorbing foot pad, blimp 2 further through Two grades of shock-absorbing foot pads are connected with air-conditioning external structure, and therefore this example has carried out two grades of compound vibration isolation to compressor 3, by subtracting Shake callosity geometry and shore hardness carry out reasonable disposition, and its vibration isolating effect will increase substantially.

Sum it up, the compressor of air conditioner noise that is given of this example and isolating technique scheme, on the one hand can significantly decay The noise sent by compressor 3, on the other hand also can significantly isolate the vibration that compressor 3 produces, thus be obviously improved air-conditioner Noise and vibration performance, particularly among integral air conditioner.
