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 refrigerator, be one of equipment that becomes vibration source, source of sound.Therefore, need to be arranged on refrigerator on implementing the bases such as vibration proof countermeasure, soundproof countermeasure.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, be not only due to the vibration of compressor self, also due to the carrying of refrigerator, movement etc. or such as shaking of the house that is caused by earthquake etc. etc., need to prevent because being subject to the damage of the cool cycles that various external force cause.
For example, if the contingency pipe arrangement sustains damage, cooling medium can not be kept the performance of cooling system due to Leakage Gas.Further, due to HC (Hydrocarbon, hydrocarbon) cooling medium etc. carries out using flammable cooling medium in the refrigerator of non-Freon reply, therefore may cause be used to preventing that cooling medium from leaking, preventing that the multiple safe design that catches 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 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 subject to larger external force in carrying, carrying.
In addition, in recent years, in the process of the whole low noise of refrigerator is also popularized, made to the machine that adopts phase inverter etc. in a large number, the vibrationproof of compressor, soundproof countermeasure required higher level.
In order to prevent changing the position and bring infringement to pipe arrangement etc. under the effect of external force as the compressor of heavier object, preferably compressor is fixed in the refrigerator main body reliably.Yet, on the contrary, when carrying out rigid body fixedly the time, can not suppress the vibration that produces from compressor, therefore need simultaneously to carry out the vibrationproof supporting and (for example, with reference to patent documentation 1) fixed in the position.
Figure 19 represents to be recorded in the structure of the existing refrigerator in 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 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 arranges on the top of vibration absorber 205 coordinates to carry out the vibrationproof supporting with hole 233.Further, be provided with at pin 243 the slip-off preventing part 260 that pin body 231 can not be come off from front end.Slip-off preventing part 260 is made of the E ring that coordinates with the slot part that is arranged on pin 243, usually is arranged on the position that does not directly contact with vibration absorber 205, pin body 231.
According to this structure, in the situation that the various carryings of refrigerator, vibration, load, the impact of bearing when mobile, even refrigerator is tilted with laying across, for being applied to the moment on compressor, horizontal load etc., because the pin 243 that bears compressor 203 is metal-mades, rigidity is higher, therefore can keep reliably compressor 203.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 being metal-made and rigidity is higher, therefore can prevent breakage, can keep compressor 203, prevents the pipe arrangement damage.
Yet in above-mentioned structure, although can guarantee fully intensity, structure member need to pass through a large amount of manufacturing procedure, assembling procedures mostly, and therefore cost is higher, 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-saving run in the opposite direction, and also can gain in weight.Further, the impact of gaining in weight and producing is fabricated onto intermediate links from product, also can be increased in the energy that uses in various carryings, movement etc.
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 pin, the position is offset significantly, puts on pin the 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 it is damaged to be provided with the base plate of pin.Like this, with pedestal 198, pin 243 and the integrated situation of resinous base plate, guaranteeing there is larger problem on intensity.

Fig. 2 represents the stereogram of 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 means the stereogram of inside, Machine Room of the refrigerator of embodiments of the present invention 1.Fig. 4 is the stereogram that the installment state of the compressor of the refrigerator of embodiments of the present invention 1 is decomposed to represent.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 extraordinarily the capacity of the storeroom of below such as vegetable compartment 103 grades.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 for the parts that compressor 203 are arranged in 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 being arranged on alap state the inside of Machine Room 201.Thus, the height of Machine Room 201 is suppressed for lower, can enlarge the accommodation space of the inside of body of thermal insulating box 101.Further, the more close base plate 204 in the center of compressor 203, the Distance Shortened of the supporting device that is therefore consisted of by pin 243, position limitation body 244 and vibration absorber 205 and the center of gravity of compressor 203.Thus, the moment that produces in the time of compressor 203 being swung reduces.Further, pin body 231 is three-dimensionally crooked structure, therefore can improve the rigidity of pin body 231, suppresses the amplitude of compressor.
In addition, as strengthen the structure of the intensity of putting restriction body 244 with respect to the impact of bearing from compressor 203, except the parts (flank) that use rectangular plate shape as above are support 245, can also realize by the thickness of slab increase that makes position limitation body 244 simply.This situation is the mode on every side that support 245 is formed on position limitation body 244.
In addition, pin 243 is cylindrical shape and the drum for being made of curved surface with position limitation body 244 and vibration absorber 205 contact-making surface each other, therefore regardless of external force direction, all can guarantee higher maintenance durability.Particularly the position of the outer surface of position limitation body 244 restriction vibration absorbers 205, therefore can guarantee higher maintenance durability.
In addition, base plate 204, pin 243, position limitation body 244 and support 245 are preferred by the resin integrated moulding.This be due to, can improve the installation strength of pin 243, position limitation 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 limitation body 244 and support 245 can adopt the 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 sell 243 pin body 231 and compare from the poroid holding section 232 that pin 243 is extracted than being used for preventing from inserting having led to, have wider limit eaves.
Under the common use state of the 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, follow the sound of this generation of vibration also to be in permissible range.Due to 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, in during long, pin 243 continues to bear the impulsive force that is produced by the vibration of above-mentioned compressor 203.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 in the position limitation body 244 of the position of restriction vibration absorber 205, resists fully impulsive force in therefore can be during long.
In addition, the impulsive force from compressor 203 that produced when falling refrigerator 100 passes to the top of pin 243 from holding section 232, makes pin 243 want crooked.The bending of pin 243 will pass to vibration absorber 205.Yet, the shift in position of the position limitation body supporting vibration absorber 205 of the position by restriction vibration absorber 205, therefore selling 243 can be crooked significantly.Further, the pin 243 impulsive forces of bearing weakened by vibration absorber 205 and disperse after pass to position limitation body 244.Therefore, not only also support impulsive force by the position limitation body 244 of tubular by pin 243, therefore also can tackle fully common use paroxysmal impulsive force in addition.
In the present embodiment, cooling medium also can be other cooling medium R134 etc.If for example use non-altogether fluorine combination cooling medium, although the Leakage Gas that causes of pipe arrangement damage for a small amount of, change constituent, and the cooling medium physical property is changed.Thereby as present embodiment, the pipe arrangement damage by the shock and vibration of eliminating because of compressor 203 causes prevents that the effect of Leakage Gas is larger.
In any, the compressor that consists of 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, in situation arbitrarily, all have in the present embodiment same effect.In addition, be also same to decompressor of using in other kind of refrigeration cycle such as external-burning circulation etc.
In addition, the foot of compressor 203 supports with four, can play a role with minimum foot more than three.
The area that position limitation body 244 bears vibration absorber 205 is larger, and the effect of the position of restriction vibration absorber 205 is larger, can scatteredload and impulsive force.Yet the bottom of compressor 203 consists of the wind path to the fan 211 of compressor 203, discharge pipe that is produced by fan 211.Therefore, in the present embodiment, each configures independently in the mode that do not form wind path and hinder to make a plurality of position limitation bodies 244, is designed to can not stop up with position limitation body 244 bottom of compressors 203.Thus, can guarantee fully wind path, make the air of bottom, discharge pipe of compressor 203 cooling.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 limitation body 244 is cylindric, but the present invention is not limited to this, for example also can be provided with respect to a vibration absorber 205 the position limitation body 244 of a plurality of (for example three, four) column around vibration absorber 205.Thus, can guarantee that above-mentioned wind path is wider.
In addition, even the combination that the layout of each chambers such as refrigerating chamber, refrigerating chamber is other also can access same effect.For example also refrigerating chamber can be placed in foot, vegetable compartment is set above refrigerating chamber, in addition, also can adopt the layout of switching chamber as the refrigerating chamber use, can access same effect.
In addition, in the present embodiment, use the situation of the pedestal that is consisted of by metallic plate than the base plate of existing Machine Room, by not re-using metallic plate as the base plate 204 of Machine Room 201, can make Machine Room 201 lightweights.Thus, as present embodiment, the refrigerator that consists of 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 from be followed successively by storeroom 102, ice-making compartment 105, can change switching chamber 106, refrigerating chamber 104 and the vegetable compartment 103 of the temperature in case, but can be also from be followed successively by the layout of refrigerating chamber, vegetable compartment, ice greenhouse and refrigerating chamber.
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, in situation arbitrarily, when the carrying refrigerator, when operation is set, can stably keep load by the compressor 203 that makes refrigerator tilt to cause by vibrationproof section 205 and position limitation body 244.In addition, can reduce by vibrationproof section 205 and position limitation body 244 vibration of compressor 203.
(embodiment 2)
Fig. 5 is the stereogram that the mounting structure state decomposition with the compressor of the refrigerator of embodiments of the present invention 2 represents.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 from embodiment 1, is cylindric.That is, 201 inside comprises the position limitation 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 the description thereof will be omitted.
Paste to pay in the position relative with compressor 203 tops of the cover 202 (Fig. 2) that covers Machine Room 201 vibrationproof material (not shown) is arranged.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 largelyr.
Under the common use state 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, follow the sound of this generation of vibration also to be 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 produce when in the situations such as the action of base plate 204 changing of the relative positions, carrying, refrigerator 100 being fallen, vibration absorber 205 limits its shift in position by the position limitation body 244 of tubular, 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 by thinner pin etc. the impulsive force that the changing of the relative positions by compressor 203 produces, and disperse to bear by the wider external surface area of vibration absorber 205 and the wider receiving area of position limitation body 244.Therefore, also can resist fully the impulsive force of long-standing vibration, load, burst.
In addition, in the present embodiment, utilize the position skew of cover 202 limit compression machines 203 on above-below direction, but by the limiting part 246 that the upper and lower displacement that arranges the pin body 231 of compressor 203 limits, also can access same effect.Limiting part 246 constitutes and makes resin component outstanding moulding integratedly on the direction of compressor 203 sides from backing 241, can suppress thus the increase of number of components.

Figure 10 means the cross-sectional perspective view of major part of inside, Machine Room of the refrigerator of embodiments of the present invention 4.Figure 11 means the stereogram of the major part of the base plate that is provided with compressor in the refrigerator of embodiments of the present invention 4.Figure 12 means the amplification stereogram of the major part of the base plate that is provided with compressor in the refrigerator of embodiments of the present invention 4.
In the present embodiment, other structure of pin and position limitation body described.Except pin 443 and position limitation body 444, all identical with embodiment 1～embodiment 3, therefore the description thereof will be omitted.
As Figure 10～shown in Figure 12, the small hole that is provided with toroidal at the upper face of position limitation body 444 is intercommunicating pore 460.This intercommunicating pore 460 is communicated with rear side from the face side of base plate 404.That is, intercommunicating pore 460 is from outside and the internal communication of position limitation body 444.In the present embodiment, the diameter of this intercommunicating pore 460 is 1.0mm.
Yet, when the foamed process of refrigerator, be filled with the heat-insulating materials 452 such as hard foam polyurethane in the inner space of resinous interior case 451 and metal outer container 450.This heat-insulating material 452 take the intensity that improves refrigerator integral body as purpose, is filled into the inner space of position limitation body 444 at the back side from base plate 404 when guaranteeing the heat-insulating property of refrigerator.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 limitation body 444.Like this, intercommunicating pore 460 is arranged on position limitation body 444 as the bleeder port of the mobility that is used for raising insulation 452.Here, with respect to a position limitation 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 flowing, therefore need until will be trapped in time till the compressed air of the inside of position limitation body 444 fully is discharged to the outside, in heat-insulating material 452 fully curing this period, the cavity that therefore produces air in the inside of position limitation body 444.Consequently, the possibility of the undesirable conditions such as rigidity reduction of generation position limitation body 444 is higher.In addition, when greater than 3.0mm, the compressed air with the inside of position limitation body 444 be discharged to outside in, heat-insulating material 452 also is 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 the workload of therefore these heat-insulating materials 452 being 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 the undesirable condition.Thus, below the above 3.0mm of the preferred 0.5mm of the diameter of this intercommunicating pore 460.
In addition, position limitation body 444 is for example for take the inside of polypropylene material moulding, its position limitation body 444 as empty shape.Be filled in this space by the heat-insulating material 452 with polyurethane, for example compared by the situation of resin forming with the integral body (also comprising the inner space) of position limitation body 444, because the proportion of comparing polyurethane with polypropylene is less, so can lightweight when the official post of this proportion must be filled at the heat-insulating material with polyurethane the inside of position limitation body 444.Thereby, can improve the stability of refrigerator main body.Therefore further, because the center of gravity of refrigerator main body is relatively low, can reduce the vibration of the refrigerator integral body that compressor causes.
In the situation that there is not intercommunicating pore 460, air trapping is in the inside of position limitation body 444 (producing air accumulates), and heat-insulating material is difficult to be filled in the upper face of position limitation body 444.Yet as present embodiment, by being provided with intercommunicating pore 460 at position limitation body 444, than the situation that does not have intercommunicating pore, the inner air that is trapped in position limitation 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 limitation body 444 uprises.Thereby even if selling 443 fractures or the head pin 206 that has that is arranged on the front end of pin 443 comes off, the pin body 231 of compressor 203 can be prevented that by 444 restrictions of position limitation body compressor 203 from becoming unstable.
In addition, intercommunicating pore 460 is arranged on the upper face of position limitation body 444, thus, the internal pressure of position limitation body 444 is the high-pressure higher than the outside pressure of intercommunicating pore 460, therefore produce pressure differential, the air of delay and heat insulating material 452 are directed to the upper face of the position limitation body 444 that is provided with intercommunicating pore 460.Consequently, till heat insulating material 452 is filled to the leading section of the position limitation body 444 that relatively is difficult to fill (being that flow impedance is high) heat insulating material 452.Therefore, the rigidity of position limitation 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 by 444 restrictions of position limitation body, can prevent that compressor 203 from becoming unstable.
In addition, particularly, intercommunicating pore 460 is arranged near angle (corner) section of the upper face of position limitation body 444.Thus, the heat-insulating material 452 of polyurethane can be directed to flow impedance higher bight.Therefore, the rigidity of position limitation body 444 further uprises, if fracture or the head pin 206 that has that is arranged on the front end of pin 443 comes off even sell 443, the pin body 231 of compressor 203 also can by 444 restrictions of position limitation body, prevent that compressor 203 from becoming unstable.
In addition, in the present embodiment, intercommunicating pore 460 arranges two with respect to a position limitation 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 can be also the hole of rectangular shape for example.
Yet intercommunicating pore 460 may not be arranged on the upper face of position limitation body 444.Even intercommunicating pore 460 is arranged on other the face such as the side surface part of position limitation body 444, also can obtain to make air to escape into outside effect when filling heat insulator 452.
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 section of pin 443, with along with to the root of pin and the mode that enlarges the pin diameter is provided with R section 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 limitation body 444 is increased.Consequently, with respect to the vibration of bearing in the carrying of refrigerator, when mobile, impact, further in the situation that the ground inclination of refrigerator traverse is put on for the moment of compressor, horizontal load etc., even in the situation that vibration absorber (not shown) contacts with position limitation body 444, than existing situation of only bearing with the pin that is positioned at central part, can make impulsive force, load.Thus, can prevent the losing of refrigerator pipe arrangement, pin, bending, and can prevent consequent noise suppressed, cooling medium Leakage Gas, thereby guarantee security.
In addition, by the root section at pin 443, R section 470 is set, can improves the rigidity of the root that the stress of pin section 443 the most easily concentrates.Thus, for the level load of the compressor that produces because of conveying of refrigerator etc., even vibration absorber bears load, also can stand this load, 443 ones of anti-shotpins lose the destruction of waiting, can suppress 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 limitation body 444 in pin 443, and increase the intensity of pin 443, the noise that therefore can prevent from being caused by pin 443 bendings, pipe arrangement bending etc. realize the refrigerator that security is higher.

As shown in figure 14, in embodiments of the present invention, the mode that increases wall thickness with the back side corresponding with pin 543 at base plate 504 arranges the protuberance 590 as heavy section that becomes one with base plate 504.Consequently, can increase the rigidity of pin 543 main bodys, guarantee intensity with respect to the load that is applied on pin 543, the disrepair phenomenon such as can prevent from losing.Thus, can realize the refrigerator that security is higher.In addition, upper face and the embodiment 4 at position limitation body 544 similarly is formed with intercommunicating pore 560.
Like this, be provided with protuberance 590 by the position at the back side of the pin 543 that is equivalent to base plate 504, can improve the rigidity of pin.Thus, level load with respect to the compressor that is caused by transporting of refrigerator etc., although vibration absorber (not shown) also bears load, but can withstand this load, can prevent the destruction of losing of 543 ones of shotpins etc., suppress that the pipe arrangement that the displacement by compressor 301 causes is damaged, the noise and vibration phenomenon.
Further, because the physical length of pin 543 is elongated, therefore by prolongation have head pin (not shown) length, and will have the head pin to be screwed into protuberance 590 till, can further improve the rigidity of pin 543.
In addition, in the present embodiment, protuberance 590 arranges integratedly with base plate 504, still also can with base plate 504 splits protuberance is set.In addition, even heavy section is not protuberance 590, in order to increase rigidity, can be also for example diameter simple thick cyclinder section, the heavy wall columnar portion thicker than pin 543.
