Specific embodiment

The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.

Refrigerating plant 100 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 4.

Refrigerating plant 100 according to embodiments of the present invention, as shown in Fig. 2, including：Box bottom 2, compressor 1 and /V Stent 3.Compressor 1 is mounted on box bottom 2, and limiting bracket 3 is equipped with to limit the upward Oscillation Amplitude of compressor 1 Upper limit position block 31.

It is understood that allow compressor 1 when refrigerating plant 100 assembles in scope internal vibration by a small margin, to consume pressure The vibrational energy generated in 1 operational process of contracting machine.But in device transportational process or the special circumstances such as 1 start and stop of compressor Under, compressor 1 vibrates excessively acutely, and Oscillation Amplitude is excessive, if the pipeline 6 being connected in Fig. 1 with compressor 1 is easily deformed, is broken, The components such as the four-way valve 5 that is connected with pipeline 6, height pressure valve 7 are also present with the problems such as deformation, damage, compressor 1 and box bottom Situations such as 2 junction equally can deform or tear, depart from.

Since the bottom of compressor 1 is connected on box bottom 2, vibrated downwards by the constraint compressor 1 of box bottom 2 Oscillation Amplitude is limited.Correlation technique additionally provides a kind of scheme, i.e., limited post is set below compressor.Limited post is used for limiting The downward vibration of compressor, the setting of limited post strengthens the constraint that box bottom vibrates downwards compressor, but is compressing When machine vibrates upwards, the junction of compressor and box bottom still has tear or deformation, the risk of disengaging, is connected with compressor Pipeline, the damaged risk of component it is still very big.

And by setting limiting bracket 3 in the embodiment of the present invention, limiting bracket 3, which is equipped with, can limit the upward of compressor 1 The upper limit position block 31 of Oscillation Amplitude, limiting bracket 3 coordinate box bottom 2 to limit the up-down vibration amplitude of compressor 1, realize pressure Vibration damping of the contracting machine 1 in operation, transport and falling process, it is excessive to avoid the stress of pipeline 6, also avoids compressor 1 and case The junction stress of body bottom plate 2 is excessive, so as to avoid due to pipeline 6 caused by shock loading or fatigue load fracture, pressure Phenomena such as junction tear or deformation, disengaging of contracting machine 1 and box bottom 2.

In some embodiments, as shown in Fig. 2, limiting bracket 3 is located on box bottom 2, the upper limit position block of limiting bracket 3 31 are set adjacent to the bottom of compressor 1.So, the junction of 31 Range compress machine 1 of upper limit position block and box bottom 2 compared with Closely, compressor 1 and the Oscillation Amplitude of the junction of box bottom 2 are limited, the junction of compressor 1 is avoided to occur tearing or take off From the phenomenon that.

Since once there is the situation for tearing or departing from, the vibration of compressor 1 in the junction of compressor 1 and box bottom 2 It can aggravate, the security risk of refrigerating plant 100 is larger, therefore upper limit position block 31 sets adjacent to the bottom of compressor 1 and is beneficial to improve The connection reliability of compressor 1 improves the security of device.

In addition, limiting bracket 3 is located on box bottom 2, device layout is also allowed for, avoids generating other component dry It relates to.

Specifically, limiting bracket 3 is rigid member, and upper limit position block 31 forms rigid constraint to compressor 1, avoids in compressor 31 stress of upper limit position block generates moderate finite deformation during 1 vibration, so as to avoid 31 deformable amount of upper limit position block is excessive from causing to compressor 1 Restriction effect reduce.

Optionally, limiting bracket 3 is nylon part or plastic part, and limiting bracket 3 can be by rigidity larger nylon or plastics It makes, on the one hand at low cost, handling ease, another aspect quality of materials is light, reduces the weight of refrigerating plant 100.

In this way, supporter 30 can play Horizontal limiting, protective effect, effectively limit compressor 1 and falling or transportational process Middle generation is significantly rocked, and is avoided compressor 1 and is collided with surrounding component, so as to avoid compressor 1 or its The problems such as component undergoes deformation of surrounding or damage, the pipeline 6 for also avoiding being connected with compressor 1 is broken.

Specifically, there is gap, supporter 30 is effectively limiting compressor 1 significantly between supporter 30 and compressor 1 While rocking, the normal operation of compressor 1 is not constrained, i.e., in 1 normal operation of compressor, supporter 30 and compressor 1 does not contact, so that supporter 30 does not influence 1 normal operation of compressor.

It should be noted that the parameters such as gap between the height of supporter 30 and compressor 1 and supporter 30 can basis The shaking amplitude size of compressor 1 determines, but is to ensure that supporter 30 will not encounter pressure in 1 normal operation of compressor Contracting machine 1.

Optionally, the outer profile area of the cross section of supporter 30 gradually increases downwards, in this way, supporter 30 and babinet bottom The connection area of plate 2 is larger, advantageously ensures that the connection reliability of supporter 30 and box bottom 2.The cross section of supporter 30 Product is gradually reduced upwards, beneficial to the weight for reducing limiting bracket 3.

Optionally, supporter 30 is formed as triangle, so as to make full use of the stability of triangle so that supporter 30 is right The support effect in the horizontal direction of compressor 1 and damping effect are preferable.

Advantageously, supporter 30 is equipped with lightening hole 301, so as to be further reduced the materials of supporter 30, reduces refrigeration The weight of device 100.

In certain embodiments, as shown in Fig. 2, limiting bracket 3 includes lower position block 32, lower position block 32 and the upper limit Position block 31 is connected on supporter 30 at interval along the vertical direction, and lower position block 32 is located at the lower section of compressor 1.

Specifically, lower position block 32 is between compressor 1 and box bottom 2, in this way, lower position block 32 can play /V And supporting role, Oscillation Amplitude downward when compressor 1 vibrates is further reduced, and lower position block 32 also can be limited effectively Compressor 1 is toppled over.

Specifically, when compressor 1 is subject to larger downward impact force, the lower position block 32 positioned at 1 lower part of compressor With the lower end in contact of compressor 1, and good supporting role is played, so as to effectively compressor 1 be prevented to continue to move down, and then Limitation compressor 1 generates larger to bottom offset.

When compressor 1 is subject to the larger power and when toppling to one side of toppling, lower position block 32 can topple with this of compressor 1 The lower end in contact of side, and good supporting role is played, continue to cover to the inclination so as to limit compressor 1, and then limit compression Machine 1 generates larger displacement of toppling.

Here, there is gap, in this way, the setting of lower position block 32 is to compressor 1 between lower position block 32 and compressor 1 Normal operation does not have any constraint, so as to achieve the purpose that not influence 1 normal operation of compressor.

Lower position block 32 is installed between compressor 1 and box bottom 2, reduces the occupied space of lower position block 32, So that the setting of lower position block 32 does not interfere with the installation and setting of 1 peripheral parts of compressor, and convenient for the wiring of peripheral parts.

Advantageously, supporter 30, upper limit part 31, lower limit part 32 are integrally formed part, so as to which limiting bracket 3 is processed into This is low, and efficiency of assembling is high.

In some embodiments, limiting bracket 3 has multiple, and multiple limiting brackets 3 are set around compressor 1.Advantageously, it is more A limiting bracket 3 is set around 1 uniform intervals of compressor.

In the above-described embodiments, box bottom 2 is equipped with multiple limiting brackets 3, and the supporter 30 of multiple limiting brackets 3 It is set around compressor 1, so multiple supporters 30 can play protective effect well to compressor 1, to limit compressor 1 The horizontal jitter generated in different directions.

The upper limit plate 31 of multiple limiting brackets 3 is set also around compressor 1, to limit compressor 1 in different directions What is generated shifts up.

The lower limiting board 32 of multiple limiting brackets 3 is set also around compressor 1, to limit compressor 1 in different directions Generate to bottom offset.

In some embodiments, as shown in Figure 1, compressor 1 includes：Compressor body 11 and chassis 12, chassis 12 are fixed It is connected on the periphery wall or bottom wall of compressor body 11, compressor 1 is mounted on by chassis 12 on box bottom 2, chassis 12 is big with the contact area of compressor body 11, firm and reliable connection.

Again as shown in Fig. 2, some compressors 1 include：Compressor body 11 and footing 13, footing 13 are fixedly connected on compression On the periphery wall or bottom wall of machine body 11, compressor 1 is mounted on by footing 13 on box bottom 2.Footing 13 is usually more A, multiple footing 13 circumferentially surround compressor body 11 and set, and with multiple 13 fixing compressors 1 of footing, are compressed beneficial to reducing The weight of machine 1 reduces the height of compressor 1.

The structure of disclosed corresponding component in the prior art can be used in the chassis 12 of compressor 1 and footing 13, here to pressure Contracting machine body, chassis, the structure of footing do not repeat.

In this embodiment, upper limit position block 31 can be located at the top on footing 13 or chassis 12, in this way, limiting bracket 3 can Compressor 1 directly is constrained using footing 13 or chassis 12, without adding component on compressor 1, device sets simpler It is single.

Specifically, as depicted in figs. 1 and 2, refrigerating plant 100 further includes shock-absorbing foot pad 4, and shock-absorbing foot pad 4 includes：Foundation 41st, card column 43 and connecting pole 42, foundation 41 are connected on box bottom 2, and connecting pole 42 is connected between foundation 41 and card column 43, Either chassis 12 is sleeved on connecting pole 42 footing 13 of compressor 1 outside and footing 13 or chassis 12 are fastened on foundation 41 and card Between column 43.

Wherein, footing 13 either chassis 12 be equipped with 101 footing 13 of mounting hole or chassis 12 by mounting hole 101 outside It is sleeved on connecting pole 42, shock-absorbing foot pad 4 is fixed on by fixing piece 45 between compressor 1 and box bottom 2.

Optionally, as shown in Fig. 2, shock-absorbing foot pad 4 is equipped with pilot hole 44, fixing piece 45 includes：Screw bolt and nut, bolt Box bottom 2, pilot hole 44 are sequentially passed through, nut compression is connected on bolt.

More specifically, the maximum compressibility of card column 43 in the up-down direction is a, footing 13 or chassis 12 and upper limit position block The distance between 31 are less than a.

Here it is possible to understand, when compressor 1 rocks upwards, footing 13 or chassis 12 move up.Card column 43 Upper end fixture 45 (such as nut) limitation fix, after footing 13 or chassis 12 drive the lower end of card column 43 to move up, 43 forced compression of card column.The maximum compressibility a of card column 43 in the up-down direction refers to the length of card column 43 when compressor 1 is static Degree is compressed into the difference of length most in short-term with card column 43 along the vertical direction.

During compressor 1 vibrates, if card column 43 is subject to the upward pressure generated by vibration, the compression of card column 43 Card column 43 can not further shorten after amount reaches a, and card column 43 is transformed into rigid member, and the upward impact force that compressor 1 vibrates transfers Onto fixing piece 45, the excessive easy loosening of 45 stress of fixing piece.It therefore will be between upper limit position block 31 and footing 13 or chassis 12 Distance be set smaller than a, card column 43 be compressed into it is most short before, compressor 1 is just limited be subject to limiting bracket 3, is reduced Compressor 1 vibrates the impact force to fixing piece 45, so as to improve the installation reliability of compressor 1.

Also have some using in example, the maximum compressibility a of card column 43 in the up-down direction is larger, if compressor 1 to On Oscillation Amplitude reach a, the pipeline 6 being connected with compressor 1 can generate gross distortion.Therefore, by footing 13 or chassis 12 The distance between upper limit position block 31 is set smaller than a, is conducive to strengthen the constraint vibrated upwards to compressor 1, further The problems such as avoiding 6 stress of pipeline excessive, pipeline 6 avoided to be broken.

Specifically, the maximum compressibility of the foundation 41 of compressor 1 in the up-down direction is carried as b, footing 13 or bottom The distance between disk 12 and lower position block 32 are less than b.

Here it is possible to understand, when compressor 1 rocks downwards, footing 13 or chassis 12 move down.Foundation 41 Lower end limitation is fixed by box bottom 2, footing 13 or chassis 12 drive the upper end of foundation 41 to move down, and foundation 41 is vibrated It moves impact force and compresses.The maximum compressibility b of foundation 41 in the up-down direction refers to the length of foundation 41 when compressor 1 is static Degree is compressed into the difference of length most in short-term with foundation 41.

In some are using example, the maximum compressibility b of foundation 41 in the up-down direction is larger, if compressor 1 is downward Oscillation Amplitude reach b, the pipeline 6 being connected with compressor 1 can generate gross distortion.Therefore, by footing 13 or chassis 12 with The distance between lower position block 32 is set smaller than b, is conducive to strengthen the constraint vibrated downwards to compressor 1, further keep away The problems such as it is excessive to exempt from 6 stress of pipeline, pipeline 6 is avoided to be broken.

Optionally, shock-absorbing foot pad 4 can be rubber parts, silica gel part or plastic part, such as ABS, PP.

Due to rubber wear-resisting, elasticity is good, elastic restoring force is strong, and it is competitively priced, resource is extensive, therefore, shock-absorbing foot pad 4 Preferably rubber pad, so as to which while improving effectiveness in vibration suppression, extending product service life, production cost can be reduced.

Advantageously, limiting bracket 3 is located at the outside of shock-absorbing foot pad 4.Here, when 1 stress of compressor is toppled, usual distance The upper-lower position variation of the central axis farthest of compressor 1 is maximum, therefore limiting bracket 3 is located to the outside of shock-absorbing foot pad 4, The Oscillation Amplitude of distance center axis farthest on compressor 1 is limited, strengthens the limitation to compressor 1, protective effect.

More specifically, the bottom of compressor 1 is equipped with multiple shock-absorbing foot pads 4, and week of the multiple shock-absorbing foot pads 4 along compressor 1 To being evenly distributed with, limiting bracket 3 is multiple, and multiple limiting brackets 3 are located at the outside of multiple shock-absorbing foot pads 4 correspondingly.

In a specific example, the bottom of compressor 1 is set there are three shock-absorbing foot pad 4, and three shock-absorbing foot pads 4 distinguish position In on three vertex of an equilateral triangle, being set on chassis 12 there are three limiting bracket 3, and three limiting brackets 3 are located at respectively The positive corresponding position in the outside of three shock-absorbing foot pads 4.Three shock-absorbing foot pads 4 are located at three vertex of an equilateral triangle respectively On, make full use of the stability of triangle so that shock-absorbing foot pad 4 is preferable to the support effect and damping effect of compressor 1.

Certainly, in embodiments of the present invention, limiting bracket 3 is not limited to structure shown in Fig. 2, for example, the bottom of compressor 1 Hook can be equipped with, and either link upper limit position block 31 is engaged with hook or link.In this way, when compressor 1 vibrates upwards, such as The Oscillation Amplitude of fruit compressor 1 is larger, and upper limit position block 31 is with regard to that can hang on hook or link, so as to can also limit compressor 1 Vibration upwards.

In addition, in the embodiment of the present invention, limiting bracket 3 is not limited to be mounted on box bottom 2, and upper limit position block 31 can also limit It makes at any position of compressor 1, is not especially limited here, as long as effectiveness in vibration suppression expected from realizing.For example, /V Stent 3 is attached on the head cover of body structure, and upper limit position block 31 extends downward into the top of compressor body 11, to limit pressure The upward Oscillation Amplitude of contracting machine 1.

In embodiments of the present invention, refrigerating plant 100 can be the device that air conditioner, refrigerator, refrigerator etc. have refrigerating function, The device heated using compressor 1 falls within refrigerating plant 100.

In one particular embodiment of the present invention, refrigerating plant 100 is air conditioner, and compressor 1 is mounted on air conditioner chamber In outer machine.

The chassis 12 of compressor 1 is connected to by shock-absorbing foot pad 4 on box bottom 2, while box bottom 2 is equipped with and is used for The limiting bracket 3 limited the Oscillation Amplitude of compressor 1.It is only set unlike the compressor of foot pad from common, this In inventive embodiments, limiting bracket 3 coordinates shock-absorbing foot pad 4, is equivalent in shock-absorbing foot pad 4 and is provided with rigid limit structure.

When the amplitude of compressor 1 is in the range of /V, i.e., even resonates that larger vibration does not occur, compressor 1 Chassis 12 is only contacted with shock-absorbing foot pad 4, and shock-absorbing foot pad 4 can play preferable effectiveness in vibration suppression, and the vibration of compressor 1 is avoided to be transferred to On body structure；When 1 amplitude of compressor is larger, when having the risk to resonate, the chassis 12 of compressor 1 will touch rigidity Position limiting structure vibrates so as to limit compressor 1, plays reduction Oscillation Amplitude, the effect for avoiding 6 stress of pipeline excessive.

Here, 3 combining structure of shock-absorbing foot pad 4- limiting brackets can regard an entirety as.As shown in figure 3, when compressor 1 Displacement when being located in the range of /V, the stiffness coefficient k of combining structure is smaller, therefore can play good vibration isolating effect, keeps away Exempt from 1 vibrational excitation of compressor to be transferred on outer container, meanwhile, the elastic-restoring force of combining structure also becomes with the displacement of compressor 1 Change substantially linear relationship change.

It jolts or during start and stop state when compressor 1 is in transport, amplitude becomes larger even beyond /V scope, combines at this time The stiffness coefficient k of structure steeply rises, and combining structure becomes " hard constraint " to compressor 1, meanwhile, the elasticity of combining structure is returned The changing ratio of multiple power F and displacement x also sharply increases, and combining structure is to the elastic recovery of compressor 1 when compressor 1 generates mobile Power increases considerably, and compressor 1 is promoted to return back to initial position, so as to ensure 6 vibration stress control of the pipeline being connected with compressor 1 System within limits, is avoided the occurrence of due to pipeline phenomenon of rupture caused by shock loading or fatigue load.
