Description
Technical field
The present invention relates to have the refrigerator of the compressor of one of constitution equipment as cool cycles.
Background technology
All the time, as the compressor of one of constitution equipment of the cool cycles of refrigerator, be parts important in the refrigerator, be one of equipment that becomes vibration source, source of sound.Therefore, need on implementing bases such as vibration proof countermeasure, soundproof countermeasure, be installed in the refrigerator.Further, compressor is to be connected by copper pipe arrangement etc. as cool cycles, and cooling medium, refrigerator oil is enclosed sealed inside uses.Therefore, only be not because the vibration of compressor self, also owing to the carrying of refrigerator, move etc. or the shaking etc. of the house that for example causes by earthquake etc., need prevent because of being subjected to the damage of the cool cycles that various external force cause.
For example, if the contingency pipe arrangement sustains damage, then cooling medium can not be kept the performance of cooling system because gas leaks.Further, because with HC (Hydrocarbon, hydrocarbon) cooling medium etc. carries out using flammable cooling medium in the refrigerator of non-Freon reply, therefore may cause being used to prevent that cooling medium from leaking, preventing that the multiple safety design of catching fire from reducing effect.
And then in recent years, for the internal volume of the storeroom that increases user bottom easy to use, the refrigerator of producing, selling adopts the structure of compressor configuration on top.In this structure, with the bottom as earthward stiff end, top is as under the free-ended vibration mode, there is the maximum situation of displacement in the compressor on top.Therefore, and compressor configuration is compared in the situation of bottom, may be subjected to bigger external force in carrying, carrying.
In addition, in recent years, also popularize in a large number, make in the process of the whole low noiseization of refrigerator at the machine that adopts phase inverter etc., the vibrationproof of compressor, soundproof countermeasure require higher level.
Bring infringement in order to prevent that compressor as heavier object from changing the position under the effect of external force to pipe arrangement etc., preferably compressor is fixed in the refrigerator main body reliably.Yet, on the contrary,, can not suppress the vibration that produces from compressor when carrying out rigid body fixedly the time, therefore need to carry out vibrationproof supporting and fixed-site (for example, with reference to patent documentation 1) simultaneously.
Figure 19 represents to be recorded in the structure of the existing refrigerator in the patent documentation 1.As shown in figure 19, existing refrigerator is screwed the pedestal (base) 198 that is made of metallic plate on resinous base plate 204.Compressor 203 is held in pedestal 198 by the vibration absorber 205 that the vibration-proof rubber by drum forms.Pedestal 198 fixes by a plurality of metal pins 243 vertically are riveted on the metallic plate 199, forms the higher structure of rigidity.
In addition, be equipped with at compressor 203 porose 233 pin body 231 is set at front end, the protuberance that is provided with on the top of vibration absorber 205 cooperates with hole 233 and carries out vibrationproof and support.Further, be provided with the slip-off preventing part 260 that pin body 231 can not be come off from front end at pin 243.Slip-off preventing part 260 is made of the E ring that cooperates with the slot part that is arranged on pin 243, is arranged on usually and the not direct position contacting of vibration absorber 205, pin body 231.
According to this structure, vibration, load, the impact of being born even make under the situation that refrigerator tilts with laying across in the various carryings of refrigerator, when mobile, for being applied to the moment on the compressor, horizontal load etc., because bearing the pin 243 of compressor 203 is metal systems, rigidity is higher, therefore can keep compressor 203 reliably.In addition, pin 243 also fixes by riveted joint with metallic plate 199, therefore can prevent shotpin 243 bendings.Further, pedestal 198 is fixed on base plate 204 reliably, and owing to be metal system and rigidity is higher, therefore can prevent breakage, can keep compressor 203, prevents the pipe arrangement damage.
Therefore yet in above-mentioned structure, although can guarantee intensity fully, structure member need pass through a large amount of manufacturing procedure, assembling procedures mostly, spends higherly, has improved manufacturing cost.In addition, in order to improve rigidity, to guarantee intensity and increase parts and formed by metal, such thinking and energy-conservationization run in the opposite direction, and also can gain in weight.Further, the influence of gaining in weight and being produced is fabricated onto the intermediate links from product, also can be increased in various carryings, move etc. in employed energy.
In addition, pedestal 198, pin 243 and the moulding integratedly of resinous base plate by being formed by metal can remove metal parts, realize the alleviating of reduction, weight of number of components, but are difficult to guarantee intensity.
Particularly, when with the fixing grade of refrigerator, for example before refrigerator roughly becomes the degree of level, there is situation about tilting significantly.Therefore, have the compressor that is installed under the state of play on the pin, the position is offset significantly, puts on the pin load overall time of compressor.Thus, the pin that is wholely set with resinous base plate can not be resisted the impulsive force from compressor fully, then sell destroyed, or be provided with the base plate breakage of pin.Like this, with pedestal 198, pin 243 and the integrated situation of resinous base plate, guaranteeing there is big problem on the intensity.

Fig. 2 is a stereogram of representing the refrigerator of embodiments of the present invention 1 from the back side.As shown in Figure 2, the top part at refrigerator 100 is formed with recess 113 in the step-like mode that becomes decline towards the back side of refrigerator 100 direction.Be formed with Machine Room 201. in addition in recess 113, in order to prevent noise, guard block, Machine Room 201 quilt covers 202 cover usually.
Fig. 3 is the stereogram of inside, Machine Room of the refrigerator of expression embodiments of the present invention 1.Fig. 4 decomposes the stereogram of representing with the installment state of the compressor of the refrigerator of embodiments of the present invention 1.As shown in Figure 3 and Figure 4,201 inside comprises compressor 203, base plate 204, vibration absorber 205 and head pin 206 is arranged refrigerator 100 in the Machine Room.
Here, Machine Room 201 is disposed at the structure at rear of the top of refrigerator 100, compare with the refrigerator of the storeroom rear area configuration compressor 203 of existing general foot at body of thermal insulating box 101, can improve the capacity of the storeroom of below such as vegetable compartment 103 grades extraordinarily.And, in the top of refrigerating chamber 102, hand is difficult to get at can not loading the space can be used as Machine Room 201, therefore can improve the capacity of taking in of the reality of refrigerator 100.
In addition, in the bottom of compressor 203, be provided with 4 (1 of inboard is not shown) pin bodies 231 with becoming outside standing shape.Pin body 231 is to be used for compressor 203 is installed in parts in the Machine Room 201, has the poroid holding section 232 that engages with pin 243 at front end.In addition, pin body 231 more is positioned at the shape of top for the bottom surface of the front end ratio piston compressor 203 of pin body 231.This is owing to will compressor 203 be installed in the inside of Machine Room 201 with alap state.Thus, the height with Machine Room 201 suppresses can enlarge the accommodation space of the inside of body of thermal insulating box 101 for lower.Further, the more close base plate 204 in the center of compressor 203, therefore the distance shortening of the supporting device that constitutes by pin 243, position restriction body 244 and vibration absorber 205 and the center of gravity of compressor 203.Thus, the moment that produces in the time of can making compressor 203 swings reduces.Further, pin body 231 is the crooked structure in three-dimensional ground, therefore can improve the rigidity of pin body 231, suppresses the amplitude of compressor.
In addition, as the structure that strengthens the intensity of putting restriction body 244 with respect to the impact of bearing from compressor 203, except the parts (flank) that use aforesaid rectangular plate shape are support 245, can also realize by the thickness of slab increase that makes position restriction body 244 simply.This situation is the mode on every side that support 245 is formed on position restriction body 244.
In addition, pin 243 is cylindrical shape and the drum for being made of curved surface with position restriction body 244 and vibration absorber 205 contact-making surface each other, therefore regardless of external force direction, all can guarantee higher maintenance durability.Particularly higher maintenance durability can be guaranteed in the position of the outer surface of position restriction body 244 restriction vibration absorbers 205 therefore.
In addition, base plate 204, pin 243, position restriction body 244 and support 245 are preferred one-body molded by resin.This be because, can improve the installation strength of pin 243, position restriction body 244, and can help to reduce number of components, manufacturing process is simplified.In addition, the forming method of base plate 204, pin 243, position restriction body 244 and support 245 can adopt existing forming methods such as vacuum forming, injection moulding.
There is head pin 206 to be mounted in the parts of the front end of pin 243.Head pin 206 is arranged slotting having led to from selling 243 pin body 231 and compare, have the limit eaves of broad from the poroid holding section 232 that pin 243 is extracted than being used for preventing.
Under the common user mode of refrigerator 100 with said structure, compressor 203 work and the vibration that produces weakens by vibration absorber 205, so the vibration of refrigerator 100 integral body is in permissible range.In addition, the sound of following this vibration to produce also is in permissible range.Because the vibration of compressor 203, compressor 203 self is with respect to base plate 204 changing of the relative positions.But the top projection that bloats shape that is positioned at vibration absorber 205 engages with the poroid holding section 232 of the front end that is positioned at pin body 231, and vibration absorber 205 engages with pin 243.Thus, pin 243 is the movable range of limit compression machine 203 indirectly, so compressor 203 can not fall or move at base plate 204 in the lump with vibration absorber 205 from vibration absorber 205.
In addition, pin 243 continues to bear the impulsive force that is produced by the vibration of above-mentioned compressor 203 in during long.Yet pin 243 can be resisted the impulsive force that is produced by the changing of the relative positions of compressor 203 as described above.Therefore, this impulsive force is scattered in vibration absorber 205, and then also can disperse to bear the position restriction body 244 in the position of restriction vibration absorber 205, therefore can resist impulsive force fully in during long.
In addition, the impulsive force that when falling refrigerator 100, was produced from compressor 203,232 tops that pass to pin 243 from the holding section make pin 243 want crooked.The bending of pin 243 will pass to vibration absorber 205.Yet, the shift in position of the position restriction body supporting vibration absorber 205 of the position by restriction vibration absorber 205, therefore selling 243 can be crooked significantly.Further, pin 243 impulsive forces of being born weakened by vibration absorber 205 and disperses after pass to the position and limit body 244.Therefore, not only also support impulsive force, therefore also can tackle common use paroxysmal impulsive force in addition fully by the position restriction body 244 of tubular by pin 243.
In the present embodiment, cooling medium also can be other cooling medium R134 etc.If for example use non-altogether fluorine mixings cooling medium,, make the constituent variation, and the cooling medium physical property is changed though then the gas that causes of pipe arrangement damage leaks to a small amount of.Thereby, as present embodiment,, prevent that the effect of gas leakage is bigger by eliminating the impact because of compressor 203, the pipe arrangement damage that vibration causes.
In any, the compressor that constitutes kind of refrigeration cycle is heavier object at reciprocating compressor, rotating engine and Vortical engine etc.Therefore, if like this with weight for adding vibration source, then under situation arbitrarily, all have same effect in the present embodiment.In addition, circulation waits that employed decompressor etc. also is same in other kind of refrigeration cycle to external-burning.
In addition, the foot of compressor 203 supports with four, can play a role with minimum foot more than three.
The area that position restriction body 244 bears vibration absorber 205 is big more, and the effect of the position of restriction vibration absorber 205 is big more, can scatteredload and impulsive force.Yet the bottom of compressor 203 constitutes the wind path to the fan 211 of compressor 203, discharge pipe that is produced by fan 211.Therefore, in the present embodiment, each disposes independently in the mode that do not form wind path and hinder to make a plurality of positions restriction bodies 244, is designed to can not limit the bottom that body 244 stops up compressors 203 with the position.Thus, wind path be can guarantee fully, the bottom of compressor 203, the air cooling of discharge pipe made.Particularly, the bottom of compressor 203 is detained in inside and is maintained refrigerator oil, prevents the rising of refrigerator oil temperature, guarantee aspect the reliability of kind of refrigeration cycle important.In the present embodiment, position restriction body 244 is cylindric, but the present invention is not limited to this, for example also can be provided with the position restriction body 244 of a plurality of (for example three, four) column with respect to a vibration absorber 205 around vibration absorber 205.Thus, can guarantee above-mentioned wind path broad.
In addition, even the layout of each chamber such as refrigerating chamber, refrigerating chamber also can access same effect for other combination.For example also refrigerating chamber can be placed foot, vegetable compartment is set above refrigerating chamber, in addition, also can adopt and to switch the chamber, can access same effect as the layout that refrigerating chamber uses.
In addition, in the present embodiment, use the situation of the pedestal that constitutes by metallic plate,, can make Machine Room 201 lightweights by not re-using the base plate 204 of metallic plate as Machine Room 201 than the base plate of existing mechanical chamber.Thus, as present embodiment, the refrigerator that constitutes even Machine Room 201 is configured in the top of refrigerator main body also can improve the stability of refrigerator main body, and reduces the vibration of refrigerator main body.
In addition, in the present embodiment, the layout of storeroom is followed successively by storeroom 102, ice-making compartment 105, can changes the switching chamber 106 of the temperature in the case, refrigerating chamber 104 and vegetable compartment 103 from last, but also can be the layout that is followed successively by refrigerating chamber, vegetable compartment, ice greenhouse and refrigerating chamber from last.
In addition, in the present embodiment, the situation that Machine Room 201 is disposed at the rear, top of refrigerator 100 is described, but the present invention is defined in this.For example Machine Room 201 for example also can be arranged on any part on the end face of refrigerator 100.In addition, also can be disposed at rear, bottom, the central portion rear of refrigerator 100.That is, under situation arbitrarily,, can stably keep load by vibrationproof portion 205 and position restriction body 244 by the compressor 203 that makes refrigerator tilt to cause when the carrying refrigerator, when operation is set.In addition, can reduce the vibration of compressor 203 by vibrationproof portion 205 and position restriction body 244.
(embodiment 2)
Fig. 5 is that the mounting structure state with the compressor of the refrigerator of embodiments of the present invention 2 decomposes the stereogram of representing.As shown in Figure 5, in the present embodiment, do not have the pin 243 of embodiment 1 and head pin 206 is arranged, in addition, vibration absorber 205 is different with embodiment 1, is cylindric.That is, 201 inside comprises the position restriction body 244 of compressor 203, base plate 204, vibration absorber 205 and tubular in the Machine Room, and does not possess the pin 243 of embodiment 1 and head pin 206 is arranged.Other structure, identical with embodiment 1, therefore omit its explanation.
Pasting to pay in the position relative with compressor 203 tops of the cover 202 (Fig. 2) that covers Machine Room 201 has vibrationproof material (not shown).Under this state, compressor 203 be arranged at cover 202 near, therefore can prevent that the displacement of the deviation ratio regulation of compressor 203 on above-below direction from changing biglyyer.
Under the common user mode of the refrigerator 100 that possesses said structure, the vibration that is produced by compressor 203 work is decayed by vibration absorber 205.Therefore, the vibration as refrigerator 100 integral body is in permissible range.In addition, the sound of following this vibration to produce also is in permissible range.
In addition, even produce load, the impulsive force of the compressor 203 that vibration by compressor 203 causes compressor 203 self and produced when under the situations such as the action of base plate 204 changing of the relative positions, carrying refrigerator 100 being fallen, the position restriction body 244 of vibration absorber 205 by tubular limits its shift in position, and the movable range of limit compression machine 203 indirectly.Therefore, compressor 203 can not produce displacement significantly or move on base plate 204 in the lump with vibration absorber 205.
In addition, can be not only bear the impulsive force that the changing of the relative positions by compressor 203 produces, and the receiving area of the broad of the external surface area of the broad by vibration absorber 205 and position restriction body 244 disperses to bear by thinner pin etc.Therefore, also can resist the impulsive force of long-standing vibration, load, burst fully.
In addition, in the present embodiment, utilize the position skew of cover 202 limit compression machines 203 on above-below direction, but, also can access same effect by the limiting part 246 that the upper and lower displacement that is provided with the pin body 231 of compressor 203 limits.Limiting part 246 constitutes and makes resin component from backing 241 outstanding integratedly moulding on the direction of compressor 203 sides, can suppress the increase of number of components thus.

Fig. 6 is that the installation constitution with the compressor of the refrigerator of embodiments of the present invention 3 decomposes the stereogram of representing.Fig. 7 is near the sectional view that is illustrated in the state lower support portion that compressor is installed in the refrigerator of embodiments of the present invention 3.Fig. 8 is the stereogram of major part of inside, Machine Room of the refrigerator of expression embodiments of the present invention 3.
In the present embodiment, other modes to support 245 describe.In addition, all identical with embodiment 2 except support 245 with embodiment 1, therefore omit its explanation.
As Fig. 6～shown in Figure 8, present embodiment and embodiment 1 similarly, position restriction body 244, vibration absorber 205, support 245, the pin 243 by tubular and have head pin 206 vibrationproof twelve Earthly Branches to hold compressor 203.Yet present embodiment also can be applicable to following structure as described in the enforcement mode 2, that is, utilize position restriction body 244, columned vibration absorber 205 and support 245 vibrationproof twelve Earthly Branches to hold compressor 203.
The support 245 of present embodiment comprises: the outer frame 245a of rectangular box shape; With the connecting portion 245b that is connected with the top of position restriction body 244 from the top of outer frame 245a with level and smooth curve.
The mode that outer frame 245a surrounds the outside of position restriction body 244 with the distance that separates regulation is configured, and is provided with from base plate 204 is outstanding integratedly.The height setting of outer frame 245a is than pin 243 height.In addition, the part that the pin body 231 of compressor 203 is passed through is provided with otch 245.Thus, support 245 can not avoided disturbing with the pin body 231 of compressor 203 contiguously.In addition, even if selling 243 fractures or the head pin 206 that has that is installed on the front end of pin 243 comes off, the pin body 231 of compressor 203 also can be supported portion's 245 supportings, can prevent the compressor skew and become unstable.
The connecting portion 245b part that to be top that body 244 is limited in the position be connected integratedly with the top of outer frame 245a.Adopt above structure, between position restriction body 244 and support 245, form the space.
Utilize such support 245, position restriction body 244 is supported securely from exterior circumferential integral body, therefore be not only under the situation of being fallen down in the back side of refrigerator 100, under the situation of falling on all directions, all can strengthen the intensity of position restriction body 244 with respect to the impulsive force of bearing from compressor 203.
In addition, it is in order to realize lightweight and to improve the resin flow mouldability that the space is set between position restriction body 244 and support 245, is not the inner real core construct that does not have the space.

Figure 10 is the cross-sectional perspective view of major part of inside, Machine Room of the refrigerator of expression embodiments of the present invention 4.Figure 11 is the stereogram of major part that is provided with the base plate of compressor in the refrigerator of expression embodiments of the present invention 4.Figure 12 is the amplification stereogram of major part that is provided with the base plate of compressor in the refrigerator of expression embodiments of the present invention 4.
In the present embodiment, other the structure to pin and position restriction body describes.Except pin 443 and position restriction body 444, all identical with embodiment 1～embodiment 3, therefore omit its explanation.
As Figure 10～shown in Figure 12, the facial small hole that is provided with toroidal is an intercommunicating pore 460 on position restriction body 444.This intercommunicating pore 460 is communicated with rear side from the face side of base plate 404.That is, intercommunicating pore 460 is from the outside and the internal communication of position restriction body 444.In the present embodiment, the diameter of this intercommunicating pore 460 is 1.0mm.
Yet when the foamed process of refrigerator, case 451 is filled with heat-insulating materials 452 such as hard foam polyurethane with the inner space of metal outer container 450 in resinous.This heat-insulating material 452 is a purpose to improve the refrigerator integral intensity when guaranteeing the heat-insulating property of refrigerator, is filled into the inner space of position restriction body 444 at the back side from base plate 404.More specifically, heat-insulating material 452 arrives the bottom surface sections of bottom 404, then the inner space of in-position restriction body 444.Blow pressure when at this moment, utilizing polyurethane foam and the air that shrinks is released to the outside from intercommunicating pore 460.Meanwhile, heat-insulating material 452 is filled into the inside of position restriction body 444.Like this, intercommunicating pore 460 is arranged on position restriction body 444 as the bleeder port of the flowability that is used to improve insulation 452.Here, with respect to a position restriction body 444, be provided with two intercommunicating pores 460.
In addition, in the present embodiment, the diameter of intercommunicating pore 460 is 1.0mm, but also can be for below the above 3.0mm of 0.5mm according to following reason.When the diameter of intercommunicating pore 460 during less than 0.5mm, opposing increases owing to flow, therefore the time till need fully being discharged to the outside until the compressed air of the inside that will be trapped in position restriction body 444, in heat-insulating material 452 curing fully this period, the therefore cavity that produces air in the inside of position restriction body 444.Consequently, the possibility of the undesirable conditions such as rigidity reduction of generation position restriction body 444 is higher.In addition, when greater than 3.0mm, when the compressed air that the position is limited the inside of body 444 was discharged to the outside, heat-insulating material 452 also was discharged to the outside from the intercommunicating pore 460 that flow impedance diminishes.Consequently, the heat-insulating material 452 of polyurethane is exposed to the surface of refrigerator, and therefore the workload that these heat-insulating materials 452 are removed increases.Further, because the use amount of polyurethane reduces significantly, so the filling rate of the heat-insulating material of refrigerator inside descends, thereby the heat-insulating property that produces refrigerator self such as reduces significantly at undesirable condition.Thus, below the above 3.0mm of the preferred 0.5mm of the diameter of this intercommunicating pore 460.
In addition, restriction body 444 in position is empty shape for the inside with polypropylene material moulding, its position restriction body 444 for example.Be filled in this space by heat-insulating material 452 polyurethane, for example compare by the situation of resin forming with the integral body (also comprising the inner space) of position restriction body 444, because compare the proportion of polyurethane with polypropylene less, so can lightweight when the official post of this proportion must be filled in the inside of position restriction body 444 at the heat-insulating material with polyurethane.Thereby, can improve the stability of refrigerator main body.Further, because the center of gravity of refrigerator main body is relatively low, therefore can reduce the vibration of the refrigerator integral body that compressor causes.
Under the situation that does not have intercommunicating pore 460, air trapping is in the inside of position restriction body 444 (producing air accumulates), and it is facial that heat-insulating material is difficult to be filled in going up of position restriction body 444.Yet as present embodiment, by being provided with intercommunicating pore 460 at position restriction body 444, than the situation that does not have intercommunicating pore, the inner air that is trapped in position restriction body 444 reduces.Therefore, the filling rate of the heat-insulating material 452 of the inner space that can improve significantly plants oneself limits body 444, so the rigidity of position restriction body 444 uprises.Thereby even if selling 443 fractures or the head pin 206 that has that is installed in the front end of pin 443 comes off, the pin body 231 of compressor 203 can be prevented that by 444 restrictions of position restriction body compressor 203 from becoming unstable.
In addition, it is facial that intercommunicating pore 460 is arranged on going up of position restriction body 444, thus, the internal pressure of position restriction body 444 is the high-pressure higher than the outside pressure of intercommunicating pore 460, therefore produce pressure differential, the air of delay and adiabatic material 452 are directed to the upward face of the position restriction body 444 that is provided with intercommunicating pore 460.Consequently, adiabatic material 452 is filled to till the difficult leading section with the position restriction body 444 of filling (being the flow impedance height) adiabatic material 452.Therefore, the rigidity of position restriction body 444 improves, if even selling 443 fractures, the head pin 206 that has that perhaps is installed on the front end of pin 443 comes off, and the pin body 231 of compressor 203 also can be limited body 444 restrictions by the position, can prevent that compressor 203 from becoming unstable.
In addition, particularly, intercommunicating pore 460 is arranged near going up facial angle (corner) portion of position restriction body 444.Thus, the heat-insulating material 452 of polyurethane can be directed to the higher bight of flow impedance.Therefore, the rigidity of position restriction body 444 further uprises, if fracture or the head pin 206 that has that is installed in the front end of pin 443 comes off even sell 443, the pin body 231 of compressor 203 also can be limited body 444 restrictions by the position, prevents that compressor 203 from becoming unstable.
In addition, in the present embodiment, intercommunicating pore 460 is provided with two with respect to a position restriction body 444, is decided to be two but also differ, and for example also can be set to the intercommunicating pore 460 more than or three.In addition, in the present embodiment, intercommunicating pore 460 is the small hole of toroidal, but also can be the hole of rectangular shape for example.
Yet it is facial that intercommunicating pore 460 may not be arranged on going up of position restriction body 444.Even intercommunicating pore 460 is arranged on other face such as the side surface part of position restriction body 444, when filling heat insulator 452, also can obtain to make air to escape into outside effect.
Figure 13 is the sectional view of the major part of pin periphery in the refrigerator of embodiments of the present invention 4.As shown in figure 13, in the root section portion of pin 443, with along with to the root of pin and the mode that enlarges the pin diameter is provided with R portion 470.That is, pin 443 forms the shape with curved surface with the cross section of the joint portion of base plate 404.Thus, the rigidity of position restriction body 444 is increased.Consequently, with respect to the vibration of being born, impact, further under the situation that refrigerator traverse ground is tilted, put on for the moment of compressor, the horizontal load etc. in the carrying of refrigerator, when mobile, even under the situation that vibration absorber (not shown) and position restriction body 444 contacts, than existing situation of only bearing, impulsive force, load are disperseed with the pin that is positioned at central part.Thus, can prevent the losing of refrigerator pipe arrangement, pin, bending, and can prevent that consequent noise suppressed, cooling medium gas from leaking, thereby guaranteeing security.
In addition, R portion 470 is set, can improves the rigidity of the easiest concentrated root of the stress of pin portion 443 by root section at pin 443.Thus, for the level load of the compressor that produces because of conveying of refrigerator etc.,, also can stand this load even vibration absorber bears load, the destruction of losing etc. of 443 ones of anti-shotpins can be suppressed pipe arrangement breakage, noise and vibration phenomenon that the displacement by compressor causes.
In addition, by similarly also being provided with intercommunicating pore 460 with position restriction body 444 in pin 443, and increase the intensity of pin 443, the noise that therefore can prevent to be caused by pin 443 bendings, pipe arrangement bending etc. realize the higher refrigerator of security.
