In addition, the width dimensions of Vacuumed insulation panel 400, identical as Fig. 4, Fig. 5 in the installation position of heat insulating box or refrigerator. That is, the side wall 790 of the width ratio such as refrigerator 1 in the left and right directions of the Vacuumed insulation panel 400 of the setting of back face wall 730 of refrigerator 1 Storeroom inner surface 791,792 between width it is small, will not block from the polyurethane thermal insulation barriers that are arranged of back side in refrigerator 1 The filling flow path of the thermal insulation barriers such as the polyurethane that charging port 703,704 is filled.
Here, Vacuumed insulation panel 400 be configured at compared to the polyurethane etc. being arranged in the left and right end portions side at the back side of refrigerator 1 every The charging port 703,704 of warmware be not exposed to outside position (such as will not block the opening of charging port 703,704 position, Or it will not obstruct or interfere the polyurethane that (such as side wall 790) flows into heat insulating box of the opening from charging port 703,704 The position of inflow of the equal thermal insulation barriers into side wall 790 or in back face wall 730 etc.) it is advisable.By being configured at for example than left and right Charging port (left charging port 703 and right charging port 704) is close to position and the upper and lower directions position of width direction central side (inside) With charging port 703,704 nonoverlapping positions, (the interior case 750 into heat insulating box will not be obstructed or interfere from charging port 703,704 Space 315 between outer container 710, such as in side wall 790, in back face wall 730) thermal insulation barriers such as the polyurethane of filling are to heat-insulated The filling in (space 315 between interior case 750 and outer container 710) in babinet, therefore not will produce the lack of fill or close of thermal insulation barriers Degree is insufficient, can obtain high performance heat insulating box, refrigerator that heat-proof quality will not decline.
Here, Vacuumed insulation panel 400 and interior case 750 (can have certainly via with the bonding agent of bonding as the main purpose The foaming heat insulation part of cementability) the direct bonding site i.e. recess portion 440 that is directly bonded, such as relative to filled with hard polyaminoester The strengthening part sandwiched position (such as protrusion 450) of equal strengthening parts has the stage portion 776 of the projecting height amount of protrusion 450, Recess portion 440 is recessed relative to protrusion 450 to depth direction (rear side).Conversely, the protrusion 450 as strengthening part sandwiched position It is prominent to the front side of depth direction relative to the recess portion 440 as direct bonding site using the amount of stage portion 776.In addition, true The direct bonding site that empty thermal insulation barriers 400 and interior case 750 are directly bonded via bonding agents such as the foaming heat insulation parts of self-adhesiveness is i.e. Recess portion 440, the step that the height (thickness) with cold air wind path 760 is measured, front side of the recess portion 440 relative to cold air wind path 760 End 769 is recessed to depth direction (rear side).Conversely, the end face 769 of the front side of cold air wind path 760 is opposite with the amount of step It is prominent to the front side of depth direction in direct bonding site.
As described above, in the present embodiment, formed by interior case 750 and outer container 710 and in interior case 750 and outer container 710 Between have in the equipment such as heat insulating box, refrigerator, cold insulated cabinet, the showcase of Vacuumed insulation panel 400, have：Indoor (example will be set to In such as storeroom) back face wall 730 in Vacuumed insulation panel 400 it is straight by the foaming heat insulation part bonding agent with self-adhesiveness Connect the direct bonding site (being recess portion 440 in figure) for pasting interior case 750；And it is pressed from both sides between Vacuumed insulation panel 400 and interior case 750 If for improving the strengthening part sandwiched position of the thermal insulation barriers such as the polyurethane as strengthening part of intensity of babinet 751 (in figure For protrusion 450).Here, Vacuumed insulation panel 400 and outer container 710 are affixed directly to by the 2nd bonding agent such as hot melt adhesive or double faced adhesive tape Together.2nd bonding agent such as hot melt adhesive or double faced adhesive tape can be pre-coated with or be pasted onto 400 side of Vacuumed insulation panel or outer container 710 Side, therefore the thickness of bonding agent can be thinned, to preferably；But may will produce coating it is uneven or paste it is unequal, therefore It is preferable to use the foaming heat insulation parts with self-adhesiveness between Vacuumed insulation panel 400 and interior case 750.
In addition, in the present embodiment, such as strengthening part sandwiched position (such as protrusion 450) and direct bonding site (such as recess portion 440) is arranged in the width direction for storing indoor sustained height position, by storing indoor width direction Left and right end portions setting strengthening part sandwiched position (such as protrusion 450) and clipped with the strengthening part sandwiched position controlled Mode be set to left and right strengthening part sandwiched position between direct bonding site (such as recess portion 440), and storeroom carry on the back The left and right directions in face forms protrusion 450 (strengthening part sandwiched position), and (the direct adhesive portion of recess portion 440 is formed between protrusion 450 Position).Here, recess portion 440 and protrusion 450 are from the intensity for ensuring babinet or ensure the angle of cold air wind path, preferably storing up Hide the substantially entire altitude range setting of indoor upper and lower directions.
So, in the position opposite with recess portion 440, make Vacuumed insulation panel 400 and outer container 710 via the 2nd bonding agent It is in direct contact or abuts, therefore thermal insulation barriers are not needed between outer container 710 and Vacuumed insulation panel 400, when with sandwiched thermal insulation barriers Compared to storage chamber volume can be increased.In addition, at direct bonding site (such as recess portion 440), make Vacuumed insulation panel 400 and interior Case 750 is contacted or is abutted via the foaming binding agent with cementability.In the present embodiment, in Vacuumed insulation panel 400 It configures position (such as recess portion 440), there is heat-proof quality and intensity by Vacuumed insulation panel 400, therefore in interior case 750 and very It need not be with heat-insulated thermal insulation barriers as the main purpose, and with heat-insulated sandwiched thermal insulation barriers as the main purpose between empty thermal insulation barriers 400 When compared to wall thickness can be thinned, therefore storage chamber volume can be increased.Here, when needing mobility as bonding agent, also may be used To use the hard polyurethane foams etc. with self-adhesiveness, make after in two-phase state inflow space 315 its foaming to It is bonded.
In the present embodiment, it can be utilized as the cold air wind path 760 blowed to the cooling indoor cold air of storage Recess portion 440, therefore the recess portion 440 that the hand of user can be made to be difficult to the storeroom back side touched is utilized effectively, so as to Efficiently use the indoor storage volume of storage.In addition, using the vacuum with scheduled intensity (bending strength, buckling strength) Protrusion 450 simultaneously (is preferably able to ensure torsional strength, the journey of buckling strength by thermal insulation barriers 400 in storeroom with scheduled width Degree) in above-below direction continuous setting when, the intensity needed for heat insulating box 700, refrigerator 1 can be obtained, and ensure torsional strength, preceding The buckling strength of rear direction or left and right directions, therefore the high heat insulating box 700 of reliability, refrigerator 1 can be obtained.As long as in addition, The intensity needed for heat insulating box 700, refrigerator 1 can be obtained and ensure that the bending of torsional strength, front-rear direction or left and right directions is strong Degree, protrusion 450 can also be arranged at one or intermittently be arranged many places without continuous setting in above-below direction.
In the present embodiment, the left and right end portions side (width direction end side) at the back side is formed by vertically in storeroom The protrusion 450 that the thermal insulation barriers 701 such as the polyurethane of direction configuration are constituted, therefore can improve babinet by forming the protrusion 450 700, the torsional strength of refrigerator 1, buckling strength.Therefore, be not in babinet 700 or the deformation of refrigerator 1 and make to be set to storeroom (example Such as refrigerating chamber 2) before the door of storage room refrigerating-chamber door 7 of (such as rotary (radial type)) tilt, for example clamshell doors In the case of the side of door (7A, 7B) of left and right the case where tilting and causing dislocation, therefore can successfully carry out door of storage room Opening and closing.In addition, the dislocation of the door of storage room of left and right will not occur, thus it is beautiful.In addition, in the case of drawer type door, it will not Make (to control set on storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, freezing chamber 6 etc.) inner wall because babinet 700 deforms Side wall) 791,792 the mounting height of track of drawer type box body or so it is different or tilt, therefore can successfully carry out box The discrepancy of body.
Here, in the present embodiment, the thermal insulation barriers such as Vacuumed insulation panel 400, the polyurethane for forming protrusion 450 need predetermined Intensity, therefore Vacuumed insulation panel 400 using Deflection Modulus of Elasticity be 20MPa or more component, formed protrusion 450 polyurethane Equal thermal insulation barriers are more than 60kg/m using Deflection Modulus of Elasticity for 13.0MPa or more (preferably 15MPa or more), density3(preferably 62kg/m3More than) component.In the past will by the thermal insulation barriers such as polyurethane obtain both babinet intensity and heat-proof quality, therefore from Ensuring that the angle of babinet intensity is set out needs to make polyurethane thermal insulation barriers to increase Deflection Modulus of Elasticity, but as the spy of hard polyaminoester If property increases Deflection Modulus of Elasticity, density increases, and heat-proof quality declines if density increases.Therefore, the polyurethane the case where Under, in order to obtain scheduled heat-proof quality, it is difficult to which it is about 10MPa or more to make Deflection Modulus of Elasticity, therefore, it is impossible to make polyurethane Thickness is thinner than for example, about 15mm.Here, the thickness of polyurethane the thin, more the thickness of wall can be reduced, increase storeroom content Product, to preferably.But in order to reduce wall thickness when the thickness of polyurethane is thinned, the density of polyurethane increases, bending resistance springform Amount also increases, therefore can increase babinet intensity, but heat-proof quality can deteriorate when density increase, and therefore, it is difficult to make the thickness of polyurethane Degree is thinner than predetermined value (such as 15mm).
In the present invention, Vacuumed insulation panel 400 using Deflection Modulus of Elasticity greatly to the component of 20MPa or more, therefore with It is equipped with the part (babinet or wall) of Vacuumed insulation panel 400, can make Vacuumed insulation panel 400 that there is heat-proof quality and intensity two Person, even if between outer container and interior case when the thermal insulation barriers such as filled polyurethane, at the position configured with Vacuumed insulation panel, without general Polyurethane can be used as being used with heat-insulated thermal insulation barriers as the main purpose as bonding agent.Therefore, can will gather The thermal insulation barriers such as urethane are as being bonded Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container 710 Bonding agent uses, therefore there is no problem the thickness for reducing polyurethane makes the heat-proof quality of polyurethane decline.Here, logical Crossing makes the covering rate of Vacuumed insulation panel 400 (the configuration area of Vacuumed insulation panel 400 is relative to babinet 700, the ratio of the surface area of door Rate) or Vacuumed insulation panel 400 filling rate (space 315 of the Vacuumed insulation panel 400 between outer container 710 and interior case 750 Shared volume ratio) greatly to more than predetermined value, even if in the presence of the position that Vacuumed insulation panel 400 is not configured, work is also ensured Heat-proof quality, intensity for heat insulating box 700.
Therefore, it is waited as shown in the embodiment in recess portion 440 and is configured with vacuum heat-insulation between outer container 710 and interior case 750 The position of part 400, when there is both intensity and heat-proof quality of babinet 700 by Vacuumed insulation panel 400, in Vacuumed insulation panel It, can be as to be bonded as the main purpose viscous between 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 Agent is connect to use hard polyurethane foams, therefore the thickness of polyurethane can be reduced, can not consider the heat-proof quality of polyurethane Decline.Therefore, even if reducing wall thickness because the thickness of hard polyurethane foams is thinned, making under the heat-proof quality of hard polyaminoester Drop, since the heat-proof quality of babinet is undertaken by Vacuumed insulation panel 400, there is no problem.Thus, it is possible to by reducing poly- ammonia The thickness of ester reduces wall thickness to increase storage chamber volume.Wherein, between outer container 710 and Vacuumed insulation panel 400 or interior Wall can be thinned when either side between case 750 and Vacuumed insulation panel 400 is using 2 bonding agents such as hot melt adhesive or double faced adhesive tapes Thickness, therefore the indoor volume of storage can be increased.
Here, as between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 The thickness of hard polyurethane foams when the bonding agent used uses is predetermined value or less or the thickness less than Vacuumed insulation panel 400 When spending, wall thickness can be reduced, therefore the indoor volume of storage can be increased.Here, for Vacuumed insulation panel 400 and outer container 710 Between or the either side between Vacuumed insulation panel 400 and interior case 750 use to be bonded hard polyurethane as the main purpose When the thickness of ester foam is less than the thickness of Vacuumed insulation panel 400, the effect that can reduce wall thickness can get.If Vacuumed insulation panel Hard polyurethane between the thickness and Vacuumed insulation panel 400 and interior case 750 of hard polyurethane foams between 400 and outer container 710 The sum of thickness of ester foam is less than the thickness of Vacuumed insulation panel 400, then can further decrease wall thickness, so as to increase storage Indoor volume.
In the present embodiment, as between Vacuumed insulation panel 400 and outer container 710 or Vacuumed insulation panel 400 and interior The bonding agent used between case 750 using hard polyurethane foams, and keeps the thickness of polyurethane as thin as possible.But it is not only Between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, Vacuumed insulation panel be not set 400 and the position (in wall) that is only filled with polyurethane can also use identical hard polyurethane foams.Vacuumed insulation panel is not set 400 and be only filled with the position (such as part in wall or in protrusion) of polyurethane since there is no Vacuumed insulation panel 400, from And the thickness of hard polyaminoester can be made to increase the amount of thickness of Vacuumed insulation panel 400, therefore the heat-insulated of polyurethane can also be increased Thickness.Therefore, with fill between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750 The thickness of polyurethane is compared, and can be increased there is no the thickness of the polyurethane at the position of Vacuumed insulation panel 400, to configured with The density of the polyurethane at the position of Vacuumed insulation panel 400 is compared, and the poly- ammonia at the position that Vacuumed insulation panel 400 is not configured can be reduced The density of ester, therefore the heat-proof quality that the polyurethane at the position of Vacuumed insulation panel 400 is not configured improves, it can be ensured that scheduled property Energy.In addition, at the position that Vacuumed insulation panel 400 is not configured, the thickness of polyurethane can be increased, therefore babinet intensity also improves. Here, in the present embodiment, in order to meet both babinet intensity and heat-proof quality, the covering rate (vacuum of Vacuumed insulation panel 400 Ratio of the configuration area of thermal insulation barriers 400 relative to babinet 700, the surface area of door) or Vacuumed insulation panel 400 filling rate (volume ratio shared by space 315 of the Vacuumed insulation panel 400 between outer container 710 and interior case 750) greatly to predetermined value with On.
In the present embodiment, there is heat-proof quality, babinet intensity by Vacuumed insulation panel 400, therefore can use The thickness of polyurethane thermal insulation barriers reduces and the intensity of polyurethane thermal insulation barriers is made to be that Deflection Modulus of Elasticity is (excellent to 13.0MPa or more greatly Select 15MPa or more) component.In addition it is also possible to which the density using polyurethane thermal insulation barriers is more than 60kg/m3(preferably 62kg/m3With On) component, therefore the thickness of polyurethane can be reduced, the wall thickness of heat insulating box 700 can also be reduced.

(wide bandgap semiconductor)
It is equipped with control device 30 in control base board room 31, and is equipped with the semiconductor fittings such as switch element, diode element, At least part semiconductor fittings such as inverting driving circuit use wide bandgap semiconductor.Furthermore, it is possible in control device 30 only Semiconductor fittings (can only be wide bandgap semiconductor) are carried, can also carry while carrying semiconductor fittings and for example control Association accessory (such as at least one in transformer, relay, converter, power supply reactor, capacitor, current detecting accessory etc. It is a) etc..
In the present embodiment, as the semiconductor fittings for being equipped on control device 30, (such as compressor 12, compressor are cold But fan, the circulating cold air drive controls such as fan 14 inverting driving circuit semiconductor etc.) use wide bandgap semiconductor. In the prior art, the semiconductor fittings such as inverting driving circuit accessory for being equipped on control device 30 are generally used with silicon (Si) For the semiconductor of matrix, but wide bandgap semiconductor is used in the present embodiment, as wide bandgap semiconductor, using being for example carbonized Silicon (SiC), gallium nitride (GaN), diamond, aluminium gallium nitride alloy (AlGaN) etc..
Wide bandgap semiconductor (such as silicon carbide SiC, gallium nitride, gallium nitride (GaN) etc.) is relative to silicon (Si) semiconductor The advantages of include following 2 points.First advantage be the loss of element it is small, can high temperature action.The calorific value of Si is more and about 100 DEG C~200 DEG C lower semiconductor reduced performances, dyskinesias, it is therefore desirable to which the fin (radiator) that heat transmission is arranged goes forward side by side one Step radiates via air, needs storage volume for carrying fin and for the space of heat dissipation.In contrast, broad stopband half Switching losses in the case of conductor (such as SiC) in element are smaller, energy saving, while being all difficult to send out until 300 DEG C or so The reduction of natural disposition energy, therefore can be used in the hot environments such as Machine Room 1A.Further, since until 300 DEG C or so all It is difficult to happen the reduction of performance, therefore with the fin for not needing heat transmission or the fin of heat transmission can be made very small (high Degree and size become smaller, thinning, miniaturization) the advantages of.
Second advantage is the thickness that can reduce the device that accessory is constituted as semiconductor.Wide bandgap semiconductor (such as SiC, GaN) insulation breakdown electric field strength it is larger, therefore the pressure resistance of semiconductor is big (about 10 times of the pressure resistance with silicon (Si)), Therefore the thickness of semiconductor devices can be made small (thin) to 1/10 or so.In the present embodiment, by using with this spy Property wide bandgap semiconductor, the substantially miniaturization of inverting driving circuit accessory, thinning may be implemented, there is no concern that dissipating-heat environment Structure etc., therefore the second best in quality refrigerator under the large and small type of degree of freedom and hot environment that design can be obtained.
It is equipped on the semiconductor fittings such as the inverting driving circuit accessory of control device 30 and uses wide bandgap semiconductor, therefore absolutely Edge destruction electric field strength is big, pressure resistance is big, so as to reducing thickness and size (being about 1/10 compared with silicon).In addition, at 300 DEG C At a high temperature of can also act, therefore the radiating fin (radiator) of semiconductor fittings cooling can be made minimum.Therefore, for It is equipped in the state of being equipped on control device 30 in the prior art compared to high heat dissipations of height such as other control association accessories Inverting driving circuit accessory, that is, semiconductor fittings of device, in the present embodiment can be extreme by using wide bandgap semiconductor Reducing makes height, the size (longitudinal and transverse width) (thinning, miniaturization) of radiator and inverting driving circuit mate, therefore To can be highly reduced in the state of being equipped on control device 30 with other control be associated with accessory (such as power supply reactor, Capacitor, transformer, current detecting accessory etc.) same degree or the equal extent height below of height.
Here, also Vacuumed insulation panel 400 is adhered directly onto by bonding agent in the part configured with control base board room 31 Outer container 710 or control base board room 31 are used as bonding agent by rigid polyurethane foam between Vacuumed insulation panel 400 and interior case 750 Foam, which is set in predetermined thickness (such as 1mm or more preferably 3mm or more and 11mm or less preferably 6mm or less) and is filled, to be advisable.
In addition, in the present embodiment, being configured to control base board room 31 being set to the upper surface of refrigerator 1 and using Vacuumed insulation panel 400 by surrounding insulation, and when the semiconductor fittings such as inverting driving circuit accessory use wide bandgap semiconductor, even if control base board room It is covered and is made in control base board room 31 under hot environment with Vacuumed insulation panel 400 or polyurethane thermal insulation barriers around 31 There is no problem.In addition, when the semiconductor fittings such as inverting driving circuit accessory use wide bandgap semiconductor, it can also be by control base board Room 31 is configured in the Machine Room 1A under hot environment.Even if wide bandgap semiconductor is compared with existing Si semiconductors in height It can also be not easy to act with breaking down under warm environment, therefore also there is no problem with thermal insulation barriers covering control base board room 31.In addition, It is set without around control base board room 31 when control base board room 31 is configured in the Machine Room 1A under hot environment It sets thermal insulation barriers etc. to be thermally shielded to prevent the temperature in control base board room 31 from becoming high temperature, therefore can be with simplify control substrate room Design can obtain compressor, the equipment of low cost.Further, since without heat-insulated to control base board room 31, therefore control can be made The size of substrate room 31 processed is thinned height corresponding with the amount of thickness of thermal insulation barriers (or reducing width, depth) and minimizes, because When this is directly bonded Vacuumed insulation panel 400 and control base board room 31, Vacuumed insulation panel 400 and interior case 750 by bonding agent, it is not necessarily to Polyurethane as thermal insulation barriers is filled, therefore wall surface (such as upper wall, the back face wall that control base board room 31 is set can be reduced Deng) wall thickness, can correspondingly increase storage chamber volume (case internal volume).
In addition, the compressor 12 that can not be arranged by the relationship in space in the prior art can be arranged in control base board room 31 Surrounding space (such as the upper space of the terminal box of compressor 12, lateral space (or surrounding space) etc.), therefore control The degree of freedom (degree of freedom of design) of the setting of substrate room 31 improves, and can obtain the sky that can be efficiently used in such as Machine Room 1A Between the equipment such as refrigerator, air conditioner.

Therefore, the gap between box body 520 and side wall 790 (length) is that the lower end of box body 520 is bigger than upper end.As a result, when It can be with when box body 520 is supported by track component 810, when track component 810 is supported below the short transverse of box body 520 Increase the volume of box body 520, therefore preferably.By track component 810 (such as box body support portion 830) box body 520 height It can increase the width of box body when 1/2 or less preferably 1/3 support box body 520 in position below, therefore box body 520 can be increased Volume.At this point it is possible in the box side wall setting box body stage portion 525 of box body 520, by the box body support portion of track component 810 830 supporting case body stage portions 525.It is possible thereby to easily support box body 520.Furthermore, it is possible in the short transverse of box body 520 Lower end (such as preferably 1/3 position below of 1/2 or less the height of box body 520) is supported, if but to as most lower The back side of the box bottom wall at end is supported, and just it is not necessary that box body stage portion 525 is arranged in box body 520, is easy to carry out box body 520 Manufacture.
In the interior case 750 and Vacuumed insulation panel 400 (or outer container 710) for forming track mounting portion, that is, recess portion hypomere portion 719 Between the density of the thermal insulation barriers 701 (such as hard polyurethane foams) such as the polyurethane filled be more than 60kg/m3When, track component carries The intensity for setting i.e. recess portion hypomere portion 719 of portion is improved, therefore even if storing weight in box body 520, mounting track component 810 Track component mounting portion, that is, recess portion hypomere portion 719 will not deform, can so as to steadily carry out the discrepancy of box body 520 Obtain the high refrigerator of reliability, equipment.
In addition, in Figure 24, Tu25Zhong, interior case recess portion 717 can store at least part (such as rail of track component 810 Road support portion 820 etc.) or all, therefore overhang of the track component 810 to storeroom side, therefore, Ke Yizeng can be reduced Indoor volume is stored greatly, further, it is also possible to increase the volume of box body 520.
In Figure 24, Tu25Zhong, for the outer container of interior case recess portion 717 made of being recessed from storeroom side in interior case 750 The example of 710 sides setting strengthening part 731 is illustrated, and Figure 26 is that protrusion forms from storeroom side in interior case 750 Interior case protrusion 727 710 side of outer container setting strengthening part 731 example.In figure, forming the interior case 750 of side wall 790 makes track Portion 755 is prominent to storeroom side, and is formed with interior case protrusion 727.Interior case protrusion 727 has protrusion epimere portion 728, protrusion hypomere Portion 729 forms convex form by protrusion epimere portion 728, protrusion hypomere portion 729.
In fig. 26, interior case protrusion 727 is in the recess shapes of recess from 710 side of outer container, and being formed in, the interior case is convex Strengthening part 731 (storage at least part is whole) is accommodated in the recess portion of 710 side of outer container in portion 727, by under protrusion Section portion carries out the positioning of the upper and lower directions or transverse direction of strengthening part 731.In addition, by being formed in the outer of interior case protrusion 727 At least part or whole that strengthening part 731 is stored in the recess portion of 710 side of case, can reduce strengthening part 731 to outer container The overhang of 710 sides, therefore it is heat-insulated to work as filled polyurethane etc. between Vacuumed insulation panel 400 (or outer container 710) and interior case 750 When part 701, the width (polyurethane between Vacuumed insulation panel 400 and strengthening part 731 for the flow path that polyurethane flows through can be inhibited The thickness of equal thermal insulation barriers 701) R the case where narrowing and polyurethane is caused to be difficult to flow.Therefore, the stream of the thermal insulation barriers such as polyurethane 701 It is dynamic to will not be blocked, to substantially ensure the thermal insulation barriers such as polyurethane between strengthening part 731 and Vacuumed insulation panel 400 701 thickness R, so as to inhibit strengthening part 731 holding intensity reduction or the tracks fixed component 735 such as screw Fixation or keep intensity reduction.
In addition, track support portion 820 and trapped orbit, that is, lower railway 812 of track component 810 pass through a bodily forms such as welding At, therefore be easy to carry out the assembling of the orbit portion 755 of 810 inside case 750 of track component.In addition, track support portion 820 is loaded In the partition wall 24 or bottom surface sections 780 between storeroom, and track component 810 is positioned to move downwards, this Outside, in partition wall 24 or bottom surface sections 780 equipped with the fixed part that track support portion 820 is fixed or kept by screw etc., and with Inhibiting track support portion 820, either track component 810 is upward or fixed part is fixed or be held in the mode of lateral movement (mobile suppressing portion).Here, being equipped with Vacuumed insulation panel 400 in partition wall 24 or bottom surface sections 780.
Track component 810 is set to 710 side of outer container of the interior case recess portion 717 of interior case 750 in Figure 24, Figure 25, in fig. 26 710 side of outer container set on interior case protrusion 727, but track component 810 is not necessarily to be set to interior case recess portion 717 or interior case protrusion 727, It can be set to the flat part of interior case 750 as shown in figure 27.
In figure 27, track component 810 is set to the orbit portion 755 of interior case 750, and orbit portion 755 is by fixed parts such as screws Part 735 is fixed on the flat surface of interior case 750.In addition, the face in 710 side of outer container of orbit portion 755 is equipped with strengthening part 731, add Strong component 731 is fixed or is kept by thermal insulation barriers 701 such as the polyurethane filled between Vacuumed insulation panel 400.At this point, plus Strong component 731 be filled in the state of being bonded by the 2nd bonding agent such as hot melt adhesive or double faced adhesive tape or fixed to interior case 750 every Warmware 701, to be kept or be fixed on interior case 750 710 side of outer container face.
In figure 27, same as Figure 24~Figure 26, the density of the thermal insulation barriers such as polyurethane 701 is more than 60kg/m3, therefore screw Etc. fixed components 735 holding intensity or fixing intensity be improved, it is suppressed that the loosening of screw deviates or falls off.In addition, The holding intensity or fixing intensity of strengthening part 731 are improved, can inhibit the dislocation of strengthening part 731 generation, because The deforming of screw, the deformation of the orbit portion of interior case 750 755, can obtain the high refrigerator of reliability, equipment caused by dislocation.
In addition, the thermal insulation barriers 701 such as polyurethane filled between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 Thickness P is set to 11mm or less (being, for example, less than 10mm), preferably 6mm hereinafter, the thermal insulation barriers such as polyurethane therefore can be increased 701 Deflection Modulus of Elasticity improves the intensity of babinet 700 or refrigerator 1.In addition, in strengthening part 731 and Vacuumed insulation panel The thickness R of the thermal insulation barriers such as the polyurethane filled between 400 701 be configured to it is smaller than predetermined thickness P, be, for example, about 6mm hereinafter, from And intensity can be further increased.
In addition, in figure 27, the end (such as lower end) of the orbit portion 755 of interior case 750 is formed with interior case 750 to storeroom Side protruding portion 757 outstanding is placed with the track support portion 820 of track component 810 in the upper surface of the protruding portion 757.The protrusion Portion 757 is configured to the prominent length than track component 810 to width direction to the prominent length of the width direction of storeroom side It is small, will not be prominent into storeroom compared to track component 810, so as to inhibit the volume of reservoir volume, box body volume to become It is small.
In addition, track support portion 820 and trapped orbit, that is, lower railway 812 of track component 810 pass through a bodily forms such as welding At, therefore be easy to for track component 810 to be assembled into the orbit portion 755 of interior case 750.In addition, track support portion 820 is placed in The upper surface of the protruding portion 757 that the end (lower end) of orbit portion 755 is formed side, and track component 810 is positioned to will not be downwards It is mobile, in addition, the fixed part that track support portion 820 is fixed or kept by screw etc. is equipped in the upper surface of protruding portion 757 side, and To inhibit track support portion 820, either fixation is fixed or be held in track component 810 upward or in a manner of lateral movement Portion's (mobile suppressing portion).
Here, in Figure 24, Tu26Zhong, orbit portion 755 is located near partition wall 24 or underside wall 780, therefore rail Road component 810 is installed near partition wall 24 or underside wall 780, and box body 520 is propped up in the lower position of short transverse Support, therefore the mounting intensity of track component 810 is improved, to preferably, and in Figure 25, Tu27Zhong, orbit portion 755 with separate Either underside wall 780 has preset distance G to wall 24 therefore track component 810 can be relative to partition wall 24 or underside wall 780 It is installed on top with preset distance G, so as to make the Support Position of box body 520 be in top, can swimmingly carry out box body Discrepancy.Further, since the length of the box body support portion 830 of track component 810 can be shortened, therefore intensity is improved, and And obtain the track component of low cost, refrigerator.
Here, box body stage portion 525 can be arranged in the box side wall of box body 520, be supported by the box body of track component 810 830 supporting case body stage portion 525 of portion.Thereby, it is possible to easily support box body 520.Furthermore, it is possible in the height side of box body 520 To lower section or lower end (such as preferably 1/3 position below of 1/2 or less the height of box body 520) be supported, but If to being supported as the back side of the lowermost box bottom wall, just without box body 520 be arranged stage portion 525, be easy into The manufacture of row box body 520.
It is being formed as track mounting portion to the interior of storeroom side orbit portion end outstanding (orbit portion protruding portion) 757 The thermal insulation barriers 701 such as the polyurethane filled between case 750 and Vacuumed insulation panel 400 (or outer container 710) (such as rigid polyurethane foam Foam) density be more than 60kg/m3When, the intensity of the orbit portion end 757 as track component mounting portion is improved, therefore i.e. Make to store weight in box body 520, track component mounting portion, that is, orbit portion protruding portion 757 of mounting track component 810 will not become Shape, therefore the discrepancy of box body 520 can be steadily carried out, the high refrigerator of reliability, equipment can be obtained.
Here, track component 810 can be set to side wall 790, point of the storeroom of configuration track component 810 can also be set to Next door (is included in the partition wall being arranged between storeroom and storeroom and the bottom surface for forming storeroom or partition wall above 24 or underside wall 780 or roof 740).I.e., it is possible to by the track support portion 820 of supporting track component 810 be set to (or It is placed in) partition wall (including partition wall 24 either roof 740 or underside wall 780).If in this way by supporting track component 810 Track support portion 820 is set to the partition wall 24 of storeroom, just it is not necessary that fixed component 735 is arranged in side wall 790, therefore can increase In the thickness of the Vacuumed insulation panel 400 of side wall configuration, furthermore, it is possible to reduce the Vacuumed insulation panel 400 in side wall 790 and interior case The thickness of the thermal insulation barriers such as the polyurethane filled between 750 701.Therefore, the indoor volume of storage or box body 520 can be increased Volume.
Here, by track support portion 820 be set to partition wall in the case of, partition wall 24 either underside wall 780 or In roof 740, it is not advisable in the position configuration Vacuumed insulation panel 400 of setting track fixed component 735.If in addition, in setting rail The position setting of road fixed component 735 is used for the strengthening part of the fixed components such as fixing screws, then the fixing intensity of fixed component Or intensity is kept to be improved.In addition, filling or applying between Vacuumed insulation panel 400 and the profile parts of formation partition wall When applying the either configuration thermal insulation barriers such as hard polyurethane foams or foam styrene, if the density of thermal insulation barriers is made to be more than 60kg/m3, Either the holding of strengthening part or fixing intensity are improved fixed component that is then fixed or keeping track component 810, therefore Reliability improves.
Above to using the situation that screw etc. is fixed (as fixed component on the inside of storeroom the orbit portion 755 of interior case 750 The head of screw of 735 screw is set to the orbit portion of interior case 750 set on the threaded portion of 2,3,4,5,6 side of storeroom, fixed component 735 The case where between 755 and Vacuumed insulation panel 400) it is illustrated.But the screw 735 of fixed component can also be made from side wall 790 Laterally therein storeroom 2,3,4,5,6 in it is prominent and fixed, at this point, head of screw is set to Vacuumed insulation panel 400 and interior case 750 Between orbit portion 755 (the either thermal insulation barriers 701 such as track strengthening part 731 or polyurethane of orbit portion 755 are fixed in threaded portion), but Even if in this case, since the density of polyurethane is more than 60kg/m3, therefore the intensity increase of polyurethane 701, screw etc. are fixed The fixing intensity of the thermal insulation barriers 701 such as the thermal insulation barriers such as component 735 and polyurethane 701, interior case 750 and polyurethane keeps intensity to increase Add, to which the deformation of interior case etc., the dislocation of strengthening part 731, loosening of screw etc. are suppressed, box body 520 can be made to wait swimmingly It pulls out (can swimmingly come in and go out).
In embodiments of the present invention, by the interior case of the opposite position in position of the setting track component with side wall 790 It is (excellent that the thickness of foaming heat insulation part (such as hard polyurethane foams) between 750 and Vacuumed insulation panel 400 is set as 11mm or less Choosing is less than 10mm), so as to increase the Deflection Modulus of Elasticity of polyurethane, therefore can be thinned while maintaining the intensity of wall Wall thickness.In addition, by the interior case 750 of the opposite position in position of the setting track component with side wall 790 and Vacuumed insulation panel 400 it Between the thickness of foaming heat insulation part (such as hard polyurethane foams) when being set as 6mm or less, polyurethane can be further increased Deflection Modulus of Elasticity, therefore can maintain wall intensity while be thinned wall thickness.
In addition, by the way that the thickness of foaming heat insulation part/(thickness of thickness+Vacuumed insulation panel of foaming heat insulation part) is set as 0.3 hereinafter, the composite guide heating rate for the composite component for being composed foaming heat insulation part and Vacuumed insulation panel can be reduced, therefore be Make thinned wall thickness that heat-proof quality also can be improved.
In addition, by making the density after polyurethane foam be more than 60kg/m3, can be thinned while maintaining the intensity of wall Wall thickness.
As above, in embodiments of the present invention, in the opposite position in position of the setting track component with side wall 790 The thickness of foaming heat insulation part (such as hard polyurethane foams) between interior case 750 and Vacuumed insulation panel 400 is that 11mm or less is (excellent Choosing be less than 10mm), by the thickness of foaming heat insulation part/(thickness of thickness+Vacuumed insulation panel of foaming heat insulation part) be set as 0.3 with Under, and the density after polyurethane foam is made to be more than 60kg/m3When, wall can further be thinned while maintaining the intensity of wall It is thick.It, therefore, can be with as the thickness of foaming heat insulation part here, the thickness of foaming heat insulation part in above formula is the thickness of polyurethane Be the thickness P of thermal insulation barriers 701 such as the polyurethane filled between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 or The thickness Q or Vacuumed insulation panel 400 of the thermal insulation barriers 701 such as the polyurethane filled between Vacuumed insulation panel 400 and interior case 750 The thickness R of the thermal insulation barriers such as the polyurethane between strengthening part 731 701.For example, the thickness of foaming heat insulation part is made to be vacuum heat-insulation When the thickness R of the thermal insulation barriers such as the polyurethane between part 400 and strengthening part 731 701, by the thickness R/ (foaming of foaming heat insulation part The thickness of the thickness R+ Vacuumed insulation panels of thermal insulation barriers) it is set as 0.3 or less.Equally, make thickness be P Q when, by thickness R is replaced as P or Q.In addition, the thickness of polyurethane shown in Figure 17, Figure 18, Figure 19 equally can also be in Vacuumed insulation panel The thickness P of the thermal insulation barriers such as the polyurethane filled between 400 and the orbit portion 755 of interior case 750 701, in Vacuumed insulation panel 400 and interior Poly- ammonia between the thickness Q of the thermal insulation barriers such as the polyurethane filled between case 750 701, Vacuumed insulation panel 400 and strengthening part 731 The thickness R of the thermal insulation barriers such as ester 701.
In addition, if the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is made to be 20MPa or more, wall thickness can further be thinned. This, can not be track component being fixed to side wall 790, and be secured to the underside wall 780 near side wall 790 or bottom surface Partition wall 24 either upper wall (roof) 740 or partition wall 24 above.Here, in the portion with the setting fixed components such as screw When Vacuumed insulation panel 400 is not configured between the opposite interior case 750 in position and outer container 710, be arranged fixed component underside wall 780 or Either roof 740 or partition wall 24 above are preferably the wall or partition wall not contacted with outer gas to following partition wall 24. It is reduced to the greatest extent in the wall (such as side wall 790, roof 740, back face wall 730, underside wall 780 etc.) contacted with outer gas and is not provided with vacuum The position of thermal insulation barriers 400, can reduce caused by heat leak lose, therefore can obtain high performance heat insulating box, refrigerator, Equipment.Thereby, it is possible to increase the configuration area of the Vacuumed insulation panel 400 of back face wall 730, side wall 790, therefore can increase heat-insulated The covering rate or filling rate of Vacuumed insulation panel 400 in babinet 700.
Here, the heat insulating box 700 of present embodiment 1, mainly undertakes with the hard polyurethane foams in heat insulating box 700 This prior art of heat insulating function thought is different, based on making Vacuumed insulation panel 400 in the part configured with Vacuumed insulation panel 400 Undertake heat-proof quality and babinet intensity this new technological thought.Therefore, the heat insulating box 700 of present embodiment 1 is so that outside The filling rate of Vacuumed insulation panel 400 in the wall formed between case 710 and interior case 750 in space 315 be (Vacuumed insulation panel 400 Ratio shared by total volume of the volume relative to space 315 in the wall formed between outer container 710 and interior case 750) it is predetermined value (being, for example, 40% or more (preferably 45% or more)) above.Here, the filling rate of Vacuumed insulation panel 400 also includes vacuum heat-insulation The volume of part 400 relative to formed door profile external door panel and door inner panel between door in space volume shared by ratio be The filling rate of door.
In the prior art, so that Vacuumed insulation panel is relative to the area ratio shared by the surface area of outer container 710 or interior case 750 Example (covering rate) mode within a predetermined range configures Vacuumed insulation panel, the thickness without considering Vacuumed insulation panel 400 It influences, therefore keeps the thickness of hard polyurethane foams bigger than the thickness of Vacuumed insulation panel 400, to have by hard polyaminoester The intensity of heat insulating box.To increase the covering rate of Vacuumed insulation panel 400 in the prior art to improve the heat-proof quality of babinet, but simultaneously The filling rate of Vacuumed insulation panel 400 is not increased to improve heat-proof quality and babinet intensity both sides, therefore Vacuumed insulation panel 400 is filled out It is smaller (such as the filling rate in existing refrigerator is about 20%) to fill rate, the case where raising there are heat-proof quality, and babinet is strong Degree depends on hard polyurethane foams.In the present embodiment, to consider the side of the filling rate of the thickness of Vacuumed insulation panel 400 Formula configures Vacuumed insulation panel 400, therefore will not improve heat-proof quality as prior art.By making Vacuumed insulation panel 400 filling rate is predetermined value or more (such as 40% or more), and heat-proof quality is improved, and can be to meet babinet strong Wall thickness is thinned while degree, heat-proof quality, therefore storage chamber volume can be increased, it can will be in the storeroom required by product Volume settings are scheduled capacity or more.I.e., it is possible to the suitably length of setting Vacuumed insulation panel 400, width, thickness, configuration Position can reduce wall thickness, can correspondingly increase storage chamber volume.
Increase the filling rate of the Vacuumed insulation panel 400 in space 315 compared with prior art in this way so that heat-proof quality It increases, therefore even if the wall thickness of heat insulating box 700 is thinned compared with prior art, can also ensure that heat-insulated compared with prior art Performance is the equal extent of the prior art or more.

(thickness of polyurethane, the filling rate of Vacuumed insulation panel)
Here, the relationship of the intensity of filling rate and babinet to Vacuumed insulation panel 400 illustrates.Figure 15 is to indicate hard The figure of the density of polyurethane foam and the relationship of thermal conductivity, Figure 16 are the density and bending resistance springform for indicating hard polyurethane foams The figure of amount, Figure 17 are the relationships of the flow path thickness of polyurethane when indicating to be filled with hard polyaminoester and the thermal conductivity of polyurethane Figure, Figure 18 is the relationship of the flow path thickness of polyurethane when indicating to be filled with hard polyaminoester and the Deflection Modulus of Elasticity of polyurethane Figure.Figure 15~Figure 18 is the mould filled hard polyaminoester between two faces with predetermined gap (flow path) and it is made to foam Experimental result under quasi- structure, the face of the side of flow path be as the 1st component steel plate (such as formed Vacuumed insulation panel or The coated steel plate of profile, that is, outer container 710 of the heat insulating box 700 of refrigerator 1), the face of the other side of flow path is as the 2nd component Resin (the copolymerization resin of butadiene, styrene (acrylonitrile), EPS (foaming modelings for example, ABS used in interior case 750 Material) etc. resins).
In Figure 15, horizontal axis indicates the density (kg/m of hard polyurethane foams3), the longitudinal axis indicates leading for hard polyurethane foams Heating rate [W/ (mK)].In addition, in Figure 16, horizontal axis indicates the density (kg/m of hard polyurethane foams3), the longitudinal axis indicates that hard is poly- The Deflection Modulus of Elasticity (MPa) of urethane foam.In Figure 17, horizontal axis indicates the flow path thickness (mm) of filling hard polyurethane foams, The longitudinal axis indicates the thermal conductivity [W/ (mK)] of hard polyurethane foams.In Figure 18, horizontal axis indicates filling hard polyurethane foams Flow path thickness (mm), the longitudinal axis indicate the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.Here, filling rigid polyurethane foam The thickness of the hard polyurethane foams of state that the flow path thickness of foam is indicated to fill hard polyurethane foams in flow path and foamed Degree.
According to Figure 15, Figure 16, hard polyurethane foams thermal conductivity, Deflection Modulus of Elasticity when density is bigger is bigger, close It is smaller that degree gets over hour thermal conductivity, Deflection Modulus of Elasticity.That is, density and thermal conductivity or density and Deflection Modulus of Elasticity are essentially just The relationship of ratio.
According to Figure 17, Figure 18, hard polyurethane foams (or are filled hard in the flow path thickness of filled polyurethane in flow path Matter polyurethane foam and the thickness of the polyurethane of state to have foamed) it is narrower when thermal conductivity it is bigger, in addition, Deflection Modulus of Elasticity It is bigger.Therefore, the thickness of the polyurethane after foaming in flow path is thicker, and thermal conductivity is smaller, and heat-proof quality is higher, but bending resistance elasticity Modulus is smaller, and intensity is lower.Therefore, when reducing the thickness of polyurethane so that wall thickness is thinned, Deflection Modulus of Elasticity increases, therefore There is no problem in intensity, but thermal conductivity becomes too much, and heat-proof quality deteriorates, therefore the thickness of polyurethane can not be made to be less than certain journey It spends (such as 15mm).
Here, in Figure 17, Tu18Zhong, if flow path thickness (or the polyurethane in flow path after foaming of filled polyurethane Thickness) narrow, then density increases, if density increases, thermal conductivity as shown in figure 15 increases, and heat-proof quality deteriorates.Here, as schemed Shown in 17, if the flow path thickness (or thickness of the polyurethane in flow path after foaming) of filled polyurethane becomes predetermined thickness (example Such as 11mm) hereinafter, if thermal conductivity increased dramatically, heat-proof quality deteriorate.Hard polyurethane foams are forming the 1st of polyurethane flow path It foams between component and the 2nd component and is solidified in the state of being adhered to the 1st component and 2 component, at this point, polyurethane forms core Layer simultaneously forms the boundary layer for being known as cortex in the both sides of the sandwich layer (the 1st component side and the 2nd component side).
Figure 23 A and Figure 23 B are the schematic diagrames of the cross sectional shape after hard polyurethane foams foaming, and Figure 23 A are indicated the 1st The schematic diagram in section when being filled with hard polyurethane foams 701A between component (interior case 750) and the 2nd component (outer container 710), Figure 23 B are to indicate to be folded with the 3rd component (Vacuumed insulation panel between the 1st component (interior case 750) and the 2nd component (outer container 710) 400) schematic diagram in section when being filled with hard polyurethane foams 701A between the 1st component and the 3rd component when.
In Figure 23 A, has the thermal wall of the foam filled polyurethane between the 1st component and the 2nd component successively by the 1st Component (case 750 in such as), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 2nd component (such as outer container 710) are constituted. On the other hand, as shown in fig. 23b, configured as the 3rd component between the 1st component (interior case 750) and the 2nd component (outer container 710) When Vacuumed insulation panel 400, thermal wall is successively by the 1st component (interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 3rd component (Vacuumed insulation panel 400), the 2nd bonding agent 715, the 2nd component (outer container 710) are constituted.In addition, the 1st cortex 701B, sandwich layer 701C and the 2nd cortex 701D constitute hard polyurethane foams 701A.
Cortex is formed in the 1st component, and nearby either the 2nd component is nearby or near the 3rd component, the flow path thickness of polyurethane When (thickness of polyurethane) is range i.e. about 20mm~30mm that the prior art uses, the thickness of the thickness of cortex relative to sandwich layer It is sufficiently small, the influence very little to density, thermal conductivity etc., but if the thickness of polyurethane be predetermined thickness (such as 11mm) hereinafter, if Ratio shared by thickness of the thickness of cortex relative to sandwich layer becomes larger, to the density of polyurethane, thermal conductivity, Deflection Modulus of Elasticity Influence increased dramatically, and density, thermal conductivity, Deflection Modulus of Elasticity drastically become larger.Therefore, heat-proof quality drastically deteriorates.In addition, as schemed Shown in 18, since the density of polyurethane rises, the Deflection Modulus of Elasticity of polyurethane also steeply rises.
Therefore, in the prior art, if reducing the thickness of polyurethane, Deflection Modulus of Elasticity increases, intensity improves, but poly- ammonia The thermal conductivity of ester rises, heat-proof quality deteriorates, therefore can not reduce the thickness of polyurethane, and the range in about 15mm~30mm makes With.In the prior art, it is configured in such a way that polyurethane is main thermal insulation barriers, Vacuumed insulation panel is auxiliary thermal insulation barriers, therefore The heat-proof quality of polyurethane thermal insulation barriers determines the thickness of polyurethane in the range of will not deteriorating, even if being also ensured that in narrow part About 15mm~20mm.
But in the present embodiment, it is main thermal insulation barriers with Vacuumed insulation panel and babinet is obtained by Vacuumed insulation panel The mode of intensity forms thermal wall, therefore the hard polyaminoester of the part configured with Vacuumed insulation panel do not require heat-proof quality, Even if if to for scheduled thickness (such as 11mm preferably 6mm) below, there is no problem, more thin then Deflection Modulus of Elasticity rising, Babinet intensity improves, therefore better.When scheduled thickness is 11mm or less, the influence of the thickness of cortex to sandwich layer becomes larger, heat conduction Rate increased dramatically, and heat-proof quality drastically reduces, thus be difficult to make in the prior art the thickness of hard polyurethane foams be 11mm with Under.In the prior art, about the thickness of hard polyurethane foams, though part small range can make predetermined value be 11mm with Under, it is also difficult to it is 11mm or less to make average thickness.In turn, if scheduled thickness be 6mm hereinafter, if cortex thickness to sandwich layer Influence further increase, heat-proof quality more deteriorates, therefore is difficult in the prior art.But in the present embodiment, make Vacuumed insulation panel 400 has the heat-proof quality of heat insulating box 700, therefore is not asked use even if the thickness that polyurethane is thinned Topic.Therefore, in the present embodiment, by the way that the thickness of hard polyurethane foams is set as 11mm or less (preferably smaller than 10mm), the Deflection Modulus of Elasticity of hard polyurethane foams can be increased, improve the intensity (rigidity) of babinet 700.If in addition, will The thickness of hard polyurethane foams is set as 6mm hereinafter, the Deflection Modulus of Elasticity of hard polyurethane foams can be further increased, Therefore the intensity (rigidity) of babinet 700 is further enhanced.
In addition, in the part that Vacuumed insulation panel 400 is not configured, the thickness of polyurethane can be with the thickness of Vacuumed insulation panel (for example, about 15mm~30mm) is formed thicker, therefore the thickness of polyurethane may insure about 20mm~40mm, can not be poly- The range (the thickness 11mm or less of polyurethane) that the thermal conductivity of urethane steeply rises uses, can be in the upper of the thermal conductivity of polyurethane The small range of lift degree (slope) (such as range that the thickness of polyurethane is such as 15mm or more) uses, therefore even if considers poly- The uneven thickness of urethane can also ensure that the heat-proof quality of polyurethane is predetermined value or less.Therefore, heat insulating box 700 can be met Intensity and heat insulating box 700 heat-proof quality both sides.
Here, in the 1st component that the face of the side of polyurethane flow path uses, using resin (for example, interior case 750 is used The ABS copolymerization resin of butadiene, styrene (acrylonitrile) or EPS (resins such as foamed plastic)).Flow path it is another The face of side is used as steel such as the aluminium-vapour deposition film of the outsourcing material of Vacuumed insulation panel, the coated steel plates (PCM) of formation outer container 710 Plate.
It will be illustrated next in the part (such as recess portion 440 or second recesses 441 etc.), poly- configured with Vacuumed insulation panel 400 The thickness of urethane relative to the thermal wall for having polyurathamc and Vacuumed insulation panel 400 thickness (thickness of Vacuumed insulation panel+ The thickness of polyurethane) ratio (thickness of=polyurethane/(thickness of polyurethane+Vacuumed insulation panel thickness)) and composite guide heating rate The relationship of (by the thermal conductivity of thermal wall made of Vacuumed insulation panel and polyurethane composition).
Figure 19 is to indicate the thickness of polyurethane when wall thickness (thickness between the inner wall of wall) is fixed as 27mm relative to by vacuum The ratio of the thickness of thermal insulation barriers made of thermal insulation barriers and polyurethane composition, the figure with the relationship of composite guide heating rate.It is horizontal in Figure 19 Axis indicate polyurethane thickness relative to by the ratio of the thickness of thermal insulation barriers made of Vacuumed insulation panel and polyurethane composition, i.e. gather The thickness of urethane/(thickness of polyurethane+Vacuumed insulation panel thickness), the longitudinal axis indicate that composite guide heating rate (by Vacuumed insulation panel and gathers The thermal conductivity that urethane combines).Here, by total, the i.e. polyurethane of the thickness of the thickness of polyurethane and Vacuumed insulation panel The thickness of thickness+Vacuumed insulation panel is as thickness in wall.
It appears from figure 19 that relative to thickness in wall, when the thickness of polyurethane is smaller, composite guide heating rate becomes smaller, heat-proof quality It improves.Here, composite guide heating rate indicates the thermal conductivity for the composite component for being composed polyurethane and Vacuumed insulation panel.In figure, Thickness changes with 0.3 for boundary's slope in thickness/wall of polyurethane, is more than 0.3 phase with thickness in thickness/wall of polyurethane Than for thickness at about 0.3 or less, slope is smaller in thickness/wall of polyurethane, and the ratio of the reduction of composite guide heating rate is smaller.Figure For the experimental verification of one timing of thickness in wall, thus in thickness/wall of polyurethane thickness ratio it is smaller, the thickness of polyurethane is got over It is small, on the contrary the thickness of Vacuumed insulation panel is bigger, therefore the thickness of Vacuumed insulation panel is bigger relative to the ratio shared by thickness in wall. That is, relative to thickness in wall, the thickness of polyurethane becomes hour, the ratio of the thickness of Vacuumed insulation panel relative to the thickness of polyurethane Increase.In figure, thickness is at about 0.6 in thickness/wall of polyurethane, and the thickness of polyurethane is bigger than the thickness of Vacuumed insulation panel, Therefore thermal conductivity being affected to composite guide heating rate (thermal conductivity of Vacuumed insulation panel and polyurethane altogether) of polyurethane, it is multiple It is also larger (heat-proof quality is poor) to close thermal conductivity.If reducing thickness in thickness/wall of polyurethane, the thickness of Vacuumed insulation panel is opposite Increase in the ratio of the thickness of polyurethane, therefore compared to the thermal conductivity of polyurethane, the thermal conductivity of Vacuumed insulation panel is to composite heat-conducting Rate is affected, as a result, becomes smaller with thickness/(thickness of thickness+Vacuumed insulation panel of polyurethane) of polyurethane, polyurethane The thermal conductivity (composite guide heating rate) for the composite component being composed with Vacuumed insulation panel reduces.Here, until polyurethane thickness/ When (thickness of thickness+Vacuumed insulation panel of polyurethane) is about 0.3, the thermal conductivity of polyurethane, the heat conduction of Vacuumed insulation panel are compared Rate is affected to composite guide heating rate, therefore the reduction ratio of composite guide heating rate is also larger, thickness/(polyurethane of polyurethane Thickness+Vacuumed insulation panel thickness) it is smaller, composite guide heating rate is smaller, and heat-proof quality greatly improves.
But from the thickness of polyurethane relative to the ratio of thickness in wall, i.e. polyurethane thickness/(thickness of polyurethane+ The thickness of Vacuumed insulation panel) be less than about 0.3 when from, the slope of the reduction of composite guide heating rate changes, the drop of composite guide heating rate Low slope becomes smaller (ratio of the reduction of composite guide heating rate becomes smaller).This is considered as since the thickness of polyurethane is relative to wall Thickness becomes smaller in thickness/wall of the ratio of interior thickness, i.e. polyurethane, to relative to composite component (by polyurethane and vacuum every The component that warmware is composed) heat-proof quality, the heat-proof quality of Vacuumed insulation panel becomes overriding, the thermal insulation of polyurethane It can become smaller to the influence of the heat-proof quality of composite component.Therefore, in the present embodiment, by composite component (polyurethane and true The heat insulating member of the adjacent formation of empty thermal insulation barriers both sides) thermal wall that is formed so that in thickness/wall of polyurethane thickness be 0.3 with Under mode when setting the thickness of polyurethane, the ratio of the reduction of heat-proof quality becomes smaller, therefore even if the thickness of polyurethane or The thickness of Vacuumed insulation panel generates unevenness, can also make the unevenness of heat-proof quality smaller, therefore preferably.Conversely, can also be by vacuum Thickness is set as 0.7 or more in thickness/wall of thermal insulation barriers.
It therefore, can when thickness in the thickness/wall for making polyurethane is to set the thickness of polyurethane in a manner of about 0.3 below To reduce composite guide heating rate, the heat-proof quality of composite component is largely increased.If in addition, considering the unevenness of the thickness of polyurethane (or unevenness of the thickness of Vacuumed insulation panel) is set so that thickness is in 0.3 model below in thickness/wall of polyurethane In enclosing, even if then the thickness of the thickness of polyurethane, Vacuumed insulation panel can inhibit the heat-proof quality of composite component if generate uneven Reduction, and the unevenness of the composite guide heating rate of composite component can be inhibited, thus can obtain reliability it is high, it is high performance every Hot wall, heat insulating box, refrigerator, equipment etc..
Figure 20 is the ratio i.e. vacuum indicated shared by the volume of the volume of Vacuumed insulation panel 400 relative to space in wall 315 The filling rate of thermal insulation barriers, with to heat insulating box 700 apply load (load) when heat insulating box deflection relationship figure. In Figure 20, horizontal axis indicates that the filling rate of Vacuumed insulation panel, the longitudinal axis indicate the deflection of heat insulating box.Here, Vacuumed insulation panel Filling rate is the ratio (ratio) of the volume shared by volume of the Vacuumed insulation panel 400 relative to the space 315 in wall, heat insulating box Deflection be about 1/4 left on the side apart from babinet in the state of having door in the heat insulating box of such as refrigerator 1 etc. Right height and position in a generally horizontal direction (being laterally, left and right directions when front openings portion is observed in front) be applied with it is scheduled The result of calculation of the upper end position of the side wall 790 of the babinet 700 when load deflection of (transverse direction) in left and right directions, if vacuum every The deflection when filling rate of warmware 400 is 20% is 1.Figure 20 is the covering rate (such as 65%) for making Vacuumed insulation panel, poly- ammonia Ester density (such as 60kg/m3), the Deflection Modulus of Elasticity of the Deflection Modulus of Elasticity (such as 9MPa) of polyurethane, Vacuumed insulation panel Wall thickness (such as 30mm) that thickness (such as 28mm), the outer container of (such as 15MPa), composite component are added with the thickness of interior case etc. is solid Determine and make the thickness change of Vacuumed insulation panel to change Vacuumed insulation panel filling rate when result.
In fig. 20, the filling rate of Vacuumed insulation panel is bigger, and box deformation amount is smaller.This be considered as due to, vacuum every The Deflection Modulus of Elasticity of warmware is bigger than the Deflection Modulus of Elasticity of polyurethane, thus with the volume of Vacuumed insulation panel relative to heat-insulated The ratio of polyurethane volume in babinet increases, and the influence of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes larger, the rigidity of babinet 700 Increase.When the filling rate of Vacuumed insulation panel 400 is 40% or more, the reduction ratio of the deflection of babinet becomes minimum, even if very The filling rate of empty thermal insulation barriers increases, and box deformation amount also hardly happens variation.This is considered as due to Vacuumed insulation panel 400 For babinet intensity (deformation of babinet) influence degree substantially close to saturation.
The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is bigger than hard polyurethane foams, therefore by increasing Vacuumed insulation panel 400 volume can contract relative to the ratio (ratio) (filling rate for increasing Vacuumed insulation panel) shared by the volume in space 315 The deflection of small heat insulating box 700, therefore the heat-proof quality of heat insulating box 700 can be improved, increase heat insulating box 700 or ice The babinet intensity of case 1 or equipment.If at this point, increasing the thickness of Vacuumed insulation panel 400 to increase filling rate, it will be able to realize Heat-proof quality is improved while the effect that the intensity of babinet improves.Here, can be increased by increasing the thickness of Vacuumed insulation panel The filling rate of big Vacuumed insulation panel, can also be by increasing surface area of the surface area of Vacuumed insulation panel 400 relative to babinet 700 Ratio (covering rate of Vacuumed insulation panel) increase the filling rate of Vacuumed insulation panel, the intensity of babinet can also be increased at this time, Also, by the covering rate for increasing Vacuumed insulation panel 400, the filling rate of Vacuumed insulation panel can be increased.If in addition, increasing vacuum The covering rate of thermal insulation barriers 400, then configuration range (configuration position) increase of Vacuumed insulation panel, can be thinned heat insulating box 700 Wall thickness, therefore the amount of storeroom internal volume increase wall thickness reduction can be made.
In the present embodiment, for example, in the outer container 710 for forming the profile of heat insulating box and the storage for forming heat insulating box At least part in the space 315 between the interior case 750 of a part for the inner wall of room has Vacuumed insulation panel 400, makes space 315 The filling rate of interior Vacuumed insulation panel 400 is 40% or more, and makes Vacuumed insulation panel 400 relative to the surface area of outer container 710 Area ratio (covering rate) is 60% or more, so as to obtain heat-proof quality is high, babinet intensity also big and reliability it is high every Hot tank body, refrigerator, equipment etc..Here, in the present embodiment, being configured to by Deflection Modulus of Elasticity than existing heat insulating box institute Hard polyurethane foams high Vacuumed insulation panels 400 undertakes the wall surface intensity of heat insulating box 700, therefore can expire simultaneously Sufficient babinet intensity and heat-proof quality, and wall thickness can be thinned, therefore storage chamber volume can also increase.
The heat insulating box 700 of present embodiment is by by the bending strength Vacuumed insulation panel 400 higher than hard polyaminoester Filling rate is set as predetermined value or more (or in preset range) or the filling rate of Vacuumed insulation panel 400 and covering rate is double Side is set as predetermined value or more (or in preset range), can meet heat-proof quality and babinet intensity simultaneously and can be thinned The wall thickness of heat insulating box 700.Therefore, without change heat insulating box 700, refrigerator 1 appearance and size can expand storage it is indoor Internal volume can increase in heat insulating box 700 storage item, reserve that either the inside of refrigerator 1 or equipment can store. In addition, when wall strength reduction, it may occur that the deformation of heat insulating box 700, for example fall set on internal 80 offset track portion of shelf, Or the storeroom (the either door of drawer type or box body or shutter door etc.) of drawer type sliding be deteriorated the problems such as.But at this In embodiment, since the filling rate of Vacuumed insulation panel 400 and/or covering rate are set as predetermined value or more (preset range It is interior), therefore the wall thickness of heat insulating box 700 can be thinned, and babinet intensity and heat-proof quality can be improved, therefore can inhibit The generation of following situations：80 offset track portion of shelf and fall or the storeroom of drawer type (either door or box body or opening and closing Door etc.) sliding be deteriorated, cause reliability to reduce.
In addition, the heat insulating box 700 of present embodiment 1 makes the filling rate of the Vacuumed insulation panel 400 in space 315 be 90% Below.According to the technological thought of above-mentioned present embodiment, it is generally desirable to all Vacuumed insulation panels 400 in space 315.But It is, as illustrated by Figure 11 etc., in overleaf wall 730 is equipped with protrusion 450 or protrusion 910, makes to be formed in addition When the orbit portion 755 of case 750 is protrusively provided into space 315, heat insulating box 700 is used for such as refrigerator 1 in addition, in wall The pipe 720 of storage harness is also configured in space 315, therefore, it is difficult to make the filling rate of Vacuumed insulation panel 400 be more than 90%, Above-mentioned harness is by will be stored in the compressor 12 carried in the Machine Room 1A for connecting heat insulating box 700, control base board room 31 Control device 30 (such as device of rotating speed etc. of control compressor) etc. wiring class boundling made of.In addition, by hot box When body 700 is applied to such as refrigerator 1, refrigerant piping 725 etc. is also configured in space 315.Therefore, in space 315 Vacuumed insulation panel 400 is inside configured more than 90%, it is necessary to the shape with wiring class 720, refrigerant piping 725, orbit portion 755 etc. The matched Vacuumed insulation panel 400 of shape, the shape of Vacuumed insulation panel 400 become complicated, to Vacuumed insulation panel 400 molding (or Person is formed) it becomes difficult, therefore the filling rate of Vacuumed insulation panel 400 is set as 90% or less.
In addition, the problem of deforming to inhibit the strength reduction of heat insulating box 700, need to make outer container 710 and interior Case 750 is Nian Jie with Vacuumed insulation panel 400 and has adhesive strength, and is equipped in interior case 750 for keeping being set to storeroom (example Such as refrigerating chamber 2) in the orbit portion 755 of shelf 80, (such as lighting device 900 either mist device 200 or separates for other accessories Wall 24 etc.) the case where it is more, it is complex-shaped.Therefore, even it is easy to Vacuumed insulation panel 400 passing through hot melt adhesive or double faced adhesive tape etc. 2nd bonding agent is adhered to 710 side of outer container, it is also difficult to so that Vacuumed insulation panel 400 is adhered to complex-shaped 750 side of interior case and obtain Adhesive strength.
But using hard polyurethane foams as the bonding agent between interior case 750 and Vacuumed insulation panel 400 in use, can So that filling, foaming while it is flowed in space 315 with two-phase state, therefore even if there are protrusions in space 315 It 450, can also be without problems by polyurethane by interior case 750 and vacuum heat-insulation when protrusion 910, orbit portion 755, other accessories Part 400 is bonded together.It is of course also possible between outer container 710 and Vacuumed insulation panel 400 or outer container 710 and interior case 750 it Between filling hard polyurethane foams as bonding agent.If being not filled by hard polyurethane foams at this point, being generated in heat insulating box 700 Be not filled by portion (i.e. gap), then the heat-proof quality of heat insulating box 700 can reduce.Therefore, in the heat insulating box of present embodiment In 700, therefore, to assure that for a degree of predetermined gap (for example, about 1mm or more, preferably needed for filling hard polyurethane foams About 3mm or more), therefore the filling rate of the Vacuumed insulation panel 400 in space 315 can be for 90% hereinafter, preferably 80% or less.
However, if the filling rate of the Vacuumed insulation panel 400 in space 315 is made to increase, the hard polyaminoester in space 315 The filling rate of foam will reduce.Therefore, the polyurethane between outer container 710 and interior case 750 thickness reduce, may result in every The babinet strength reduction of hot tank body 700.But the heat insulating box 700 of present embodiment is by using heat-proof quality, bending rigidity All Vacuumed insulation panels 400 better than polyurethane, can inhibit the reduction of babinet intensity.In addition, in the present embodiment, technology is thought Want mainly to undertake heat insulating function and intensity by the small Vacuumed insulation panel 400 of thermal conductivity, therefore as shown in figure 20, by making vacuum The filling rate of thermal insulation barriers is 40% or more, even if the loading of hard polyaminoester is reduced, can also improve the intensity of babinet 700. In addition, as shown in figure 19, by thickening the thickness (filling rate for increasing Vacuumed insulation panel) of Vacuumed insulation panel 400, can contract The composite guide heating rate of the small compound heat-insulation part for being composed Vacuumed insulation panel and hard polyurethane foams, therefore babinet 700 Heat-proof quality also improves.
If here, increasing the density of hard polyurethane foams to increase Deflection Modulus of Elasticity (bending rigidity), hard is poly- The urethane foam heat-proof quality of itself can reduce, but by make Vacuumed insulation panel 400 covering rate and filling rate be predetermined value with On, the influence of the reduction of the heat-proof quality of polyurethane can become smaller without becoming problem.In the heat insulating box 700 of present embodiment In, as shown in figure 16, by make hard polyurethane foams the density ratio prior art it is big, be greater than 60kg/m3, can make The Deflection Modulus of Elasticity of hard polyurethane foams is the bending resistance bullet than hard polyurethane foams used in existing heat insulating box The big 15MPa or more of property modulus (for example, about 6~10MPa), can also improve the babinet for the part that Vacuumed insulation panel 400 is not configured Intensity.Therefore, the equipment such as heat insulating box 700, refrigerator 1, showcase, hot water supply device of present embodiment, by making vacuum heat-insulation The filling rate of part 400 is 40% or more, the laterodorsal covering rate of Vacuumed insulation panel is made to be 70% or more, can be inhibited because of hard Strength reduction caused by the reduction of the filling rate of polyurethane foam, additionally it is possible to inhibit heat insulating box 700 because storage item can not be resistant to Weight caused by it is crooked and deform.That is, the filling rate by increasing Vacuumed insulation panel 400, can improve heat insulating box 700 Intensity, furthermore, it is possible to obtain excellent heat-proof quality, therefore it is high and energy-efficient have Vacuumed insulation panel to obtain reliability Heat insulating box, the refrigerator for having Vacuumed insulation panel, the showcase for having Vacuumed insulation panel, the supplying hot water dress for having Vacuumed insulation panel The equipment etc. for setting, having Vacuumed insulation panel.
In addition, the density adjustment of hard polyurethane foams, such as can be by the hard polyurethane that makes to be injected into space 315 The amount of the stoste of ester foam fill more than the prior art (lengthen injection length or increase injection pressure) and by density tune It is larger or smallerly whole.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams as shown in figure 16 with the size of density substantially at Increase to ratio, therefore increase density to increase Deflection Modulus of Elasticity, and when Deflection Modulus of Elasticity is larger, gear housing rigidity increases Greatly, therefore preferably, but the Deflection Modulus of Elasticity of polyurethane is preferably 150MPa or less.The bending resistance springform of hard polyurethane foams Amount becomes too much if more than 150MPa, the then density of hard polyurethane foams, can not be foamed into spongy and solidify, thermal insulation It can drastically reduce, therefore when Deflection Modulus of Elasticity of hard polyurethane foams is 150MPa or less can inhibit the drop of heat-proof quality It is low to preferably, high performance heat insulating box can be obtained.
In the present embodiment, the refrigerator by heat insulating box 700 for example applied to following specification.
(1) using the plate thickness and interior case that total plate thickness of outer container 710 and interior case 750 is about 2mm or less including outer container 710 The average wall thickness of the heat insulating box 700 of 750 plate thickness is about 20mm or more about 40mm heat insulating boxes below (here, eliminating outer The average distance (thickness in wall) in the wall thickness direction in the space 315 of the plate thickness of case 710 and interior case 750 is about 18mm~about 38mm).
(2) thickness of Vacuumed insulation panel 400 is about 10mm~about 30mm, and the part configured with Vacuumed insulation panel is (such as recessed Portion 440 or second recesses 441) wall in space 315 in hard polyurethane foams wall thickness direction mean flowpath width (polyurethane flow path thickness) is 1mm or more (preferably 3mm or more), 11mm or less (preferably 6mm or less).
(3) thermal conductivity of hard polyurethane foams is 0.018W/ (mK)~0.026W/ (mK).
(4) thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (mK)~0.0025W/ (mK).
(5) internal volume is 200L~600L grades, the consumption electric power under predetermined condition is about 60W or less degree.
The heat-proof quality of this refrigerator 1 makes the filling rate of Vacuumed insulation panel 400 and covering rate be in predetermined by being set to In the range of and select the size of Vacuumed insulation panel 400, thickness, make Vacuumed insulation panel 400 relative to the thermal insulation of heat insulating box Can, the babinet intensity of heat insulating box become overriding, when smaller to the thermal conductivity of Vacuumed insulation panel 400, can reduce every The composite guide heating rate of hot tank body is to which preferably, preferably 0.0030W/ (mK) is below.If the thermal conductivity of Vacuumed insulation panel 400 is super 0.0030W/mK is crossed, then the influence that wall thickness is reduced to heat-proof quality becomes larger, and heat-proof quality deteriorates, and power consumption increases.Cause This, in the present embodiment, by make Vacuumed insulation panel 400 thermal conductivity be 0.0030W/ (mK) hereinafter, can inhibit with The influence that the opposite heat-proof quality of wall thickness reduces is thinned.In addition, the thermal conductivity of Vacuumed insulation panel 400 is the smaller the better, but in order to incite somebody to action The cost that thermal conductivity reduces spent by 0.001W/ (mK) substantially increases, therefore is using the thermal conductivity of Vacuumed insulation panel 400 The component of 0.0012W/ (mK) or more.If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (mK) above 0.0025W/ (mK) hereinafter, it is about 10 times just smaller than the thermal conductivity of hard polyurethane foams, therefore the heat-proof quality of heat insulating box 700 is compared The prior art is especially good, disclosure satisfy that product specification.Therefore, Vacuumed insulation panel 400 is about 0.0012W/ (m using thermal conductivity K) the component that the above 0.0030W/ (mK) (is preferably from about 0.0019W/ (mK) the above 0.0025W/ (mK) below) below .
An example of heat insulating box 700 as embodiments of the present invention, is shown in table 1 wall thickness and Vacuumed insulation panel The relationship of the box deformation amount of 400 filling rate, the Deflection Modulus of Elasticity of hard polyurethane foams, heat insulating box 700.Table 1 1 is existing specification, be wall thickness be 40mm, the filling rate of Vacuumed insulation panel 400 is 20%, in interior case 750 and vacuum heat-insulation The result when Deflection Modulus of Elasticity for the polyurethane filled between part 400 is 9MPa.Here, the bending resistance bullet of Vacuumed insulation panel 400 Property modulus use 20MPa component.According to the item 1 and item 2 of table 1, the filling rate of Vacuumed insulation panel 400 is 20%, polyurethane When Deflection Modulus of Elasticity is 9MPa, if the wall thickness of heat insulating box 700 is made to be thinned to 30mm, babinet strength reduction from 40mm.Cause This, as shown in item 3 it is found that in the case where making wall thickness reduction to 30mm, if the filling rate of Vacuumed insulation panel 400 is made to increase to 40% or more, although then box deformation amount is more slightly larger than item 1 (prior art), it is reduced to same with item 1 (prior art) Degree.
As shown in the item 4 of table 1, even if the wall thickness of heat insulating box 700 is thinned to from existing 40mm (item 1 of table 1) 30mm, as long as making, the filling rate of Vacuumed insulation panel 400 is 40% or more and the Deflection Modulus of Elasticity of polyurethane is 15Mpa or more (item 4 of table 1), so that it may so that box deformation amount is smaller than the prior art (item 1), therefore the babinet of heat insulating box 700 can be made strong Degree is existing component (item 1) or more.That is, even if wall thickness (such as being reduced to 30mm from 40mm) is reduced, as long as by Vacuumed insulation panel 400 filling rate and the Deflection Modulus of Elasticity of polyurethane are set as predetermined value or more, so that it may to improve with not reducing babinet intensity Heat-proof quality.Therefore, in the present embodiment, Deflection Modulus of Elasticity 20MPa or more is used by being used as Vacuumed insulation panel 400 Component, and the filling rate of Vacuumed insulation panel 400 is set as 40% or more, sets the Deflection Modulus of Elasticity of hard polyurethane foams It is set to 15MPa or more, it, can also be compared with prior art even if the wall thickness (such as being thinned to 30mm from 40mm) of heat insulating box is thinned Improve the intensity of heat insulating box 700.

More than, in the heat insulating box 700 of present embodiment, the covering rate of Vacuumed insulation panel 400 is made to be more than predetermined value (60%) (the laterodorsal covering rate of Vacuumed insulation panel 400 is made to be 70% or more).In addition, making the filling of Vacuumed insulation panel 400 Rate is also predetermined value (40%) or more to reduce the loading of hard polyurethane foams, therefore can ensure the heat-insulated of heat insulating box Performance and babinet intensity, at the same can make heat insulating box 700 the wall ratio prior art it is thin.Therefore, heat-proof quality is carried Height can make the amount of the indoor internal volume increase wall thickness reduction of storage compared with prior art to energy saving, so as to carry For the heat insulating box 700 of internal volume good efficiency, refrigerator 1, showcase, equipment.That is, according to the embodiment of the present invention, it is constant The appearance and size of more heat insulating box 700 either equipment such as refrigerator 1 or showcase can increase internal volume (example compared with prior art Such as the internal volume of storeroom 2~6), therefore the comparable prior art increases heat insulating box 700 or the inside of refrigerator 1 and can store Storage item.Thereby, it is possible to obtain the equipment such as user easy to use, energy-efficient heat insulating box 700, refrigerator 1, showcase.Conversely, If keeping internal volume (such as internal volume of storeroom 2~6) same with the prior art, appearance and size can be reduced, therefore can obtain Obtain the equipment such as energy saving and compact heat insulating box 700, refrigerator 1, showcase, hot-water supply.
In addition, the only an example of heat insulating box 700, the mode of refrigerator 1, shape shown in present embodiment.For example, The reserve storage space of heat insulating box 700 can in above-below direction be formed to four storage skies with 3 cross septation plate zonings Between (storeroom).In addition, for example the reserve storage space of heat insulating box 700 can also be gone forward side by side with 3 cross septation plate zonings One step is with demarcation strip zoning is indulged, to form five storage spaces (storeroom).By increasing the quantity of demarcation strip 24, Ke Yijin One step improves the intensity of heat insulating box 700.That is, increase demarcation strip 24 quantity to increase the quantity of receiving room, storeroom, The effect that babinet intensity is improved by demarcation strip can be obtained, even if to which the portion covered by Vacuumed insulation panel 400 be thinned Point hard polyurethane foams (space 315 between Vacuumed insulation panel 400 and interior case 750) average thickness (such as 11mm with Under, preferably smaller than 10mm, more preferably 6mm or less), enough babinet intensity is also ensured.Therefore, do not change heat insulating box 700 appearance and size can further increase the internal volume of storeroom, and the inside that can further increase heat insulating box 700 can The storage item of storage.
In addition, can be same as heat insulating box 700 about the internal structure of demarcation strip 24 in the present embodiment It constitutes.That is, configuring Vacuumed insulation panel 400 in the inner space of demarcation strip 24 and filling hard polyurethane foams, but hard polyurethane As long as ester foam is used as bonding agent, therefore can be relatively thin, such as can be about 11mm or less, be preferably smaller than 10mm, be more excellent It is selected as about 6mm or less.Here, the feelings of piping 725, wiring 720 etc. are not configured as heat insulating box 700 in demarcation strip 24 Condition is more, therefore in this case, although filling rate that can also be by Vacuumed insulation panel 400 relative to demarcation strip 24 is set as 40% or more 90% same with heat insulating box 700 in the size of demarcation strip 24 hereinafter, but about partition wall 24, (can separate Space in plate 24) substantially entire surface configure Vacuumed insulation panel 400, therefore the filling rate of Vacuumed insulation panel 400 can be carried Height arrives about 40% or more 95% or less.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams is 15MPa or more, density is more than 60kg/m3It is advisable.Vacuumed insulation panel 400 is also configured in demarcation strip 24 and filling rate is set in preset range in this way, The heat-proof quality of heat insulating box 700 can be further increased.
In the present embodiment, in the case of the heat insulating box or thermal wall for having Vacuumed insulation panel, consider assembling Property and Vacuumed insulation panel 400 is adhered directly onto by the 2nd bonding agent different from polyurathamc such as hot melt adhesive or double faced adhesive tape Outer container 710, as to be bonded bonding agent filling hard polyurethane as the main purpose between Vacuumed insulation panel 400 and interior case 750 Ester foam, but can also in the space 315 being formed between outer container 710 and interior case 750 configuration by the resins such as EPS formed every Vacuumed insulation panel 400 is floated on and is configured between interior case 750 and outer container 710 from object etc., and in Vacuumed insulation panel 400 and outside Hard polyurethane foams are filled between case 710 and between Vacuumed insulation panel 400 and interior case 750.In addition it is also possible to by vacuum every Warmware 400 is adhered directly onto interior case 750 and in Vacuumed insulation panel 400 and outer container by the 2nd bonding agent such as hot melt adhesive or double faced adhesive tape Filled polyurethane foam between 710.
Here, when making Vacuumed insulation panel 400 float on by spacer etc. to be configured between outer container 710 and interior case 750, It can be in the inner face side (space between outer container 710 and Vacuumed insulation panel 400) of outer container 710 setting spacer and in spacer sky Between setting refrigerant piping 725 (such as condensation piping).Refrigerant piping 725 is also to make from the compression being configured in the 1A of Machine Room The condensation piping of the refrigerant flowing for the high temperature and pressure that machine 12 is discharged, is leading via the tube wall and outer container 710 of refrigerant piping 725 Under the action of heat etc., the refrigerant flowed in piping 725 is made to keep refrigerant cold by the air cooling around piping 725 It is solidifying, to be used as condensation piping.In addition, the heat insulating box 700 of present embodiment is nonoverlapping with refrigerant piping 725 The resin of thickness more than diameter of the inner wall setting with refrigerant piping 725 of the outer container 710 of position (not opposite position) The spacer of system, and Vacuumed insulation panel 400 is made to paste spacer, so, make refrigerant piping 725 close to outer container 710 Ground with postponing, can by the spacer for being pasted with Vacuumed insulation panel 400 in a manner of covering refrigerant piping 725 directly with two-sided Glue etc. pastes outer container 710, easily fabricated.Vacuumed insulation panel 400 is configured to and interior case by the heat insulating box 700 of present embodiment 750 at predetermined spaced intervals, and Vacuumed insulation panel 400 is configured to outer container 710 at predetermined spaced intervals, therefore becomes vacuum Thermal insulation barriers 400 are embedded in the composition in hard polyurethane foams, and heat-proof quality is improved.
As described above, in the present embodiment, the space that heat insulating box 700 can be between outer container 710 and interior case 750 It is foam filled so that Vacuumed insulation panel 400 is embedded in hard polyurethane foams, in this case in outer container 710 and vacuum in 315 The case where there is condensation piping 725 between thermal insulation barriers 400 is more, but can be by being configured to the isolation using resins such as EPS Object etc. makes Vacuumed insulation panel 400 have scheduled distance with outer container 710, to configure Vacuumed insulation panel 400.
In addition, Vacuumed insulation panel 400 when as high temperature, is easy to absorb the gas of surrounding, internal vacuum degree can be caused It reduces, thermal conductivity deteriorates.In the case of the outside air temperatures height such as summer, the ambient temperature (air themperature of surrounding) of outer container 710 It getting higher, the temperature of itself of outer container 710 may also be got higher, in addition, also become high temperature as the piping 725 that condensation piping uses, because This preferably makes Vacuumed insulation panel 400 far from outer container 710, refrigerant piping from the angle for the reliability for ensuring Vacuumed insulation panel 400 (condensation piping) 725.By making Vacuumed insulation panel 400 far from outer container 710, refrigerant piping (condensation piping) 725, can inhibit Vacuumed insulation panel 400 is deteriorated because of caused by temperature rise, if therefore Vacuumed insulation panel 400 is made to float with remote by spacer etc. Wall surface from outer container 710 or refrigerant piping 725, so that it may to inhibit the reduction of heat-proof quality, reliability can be provided for a long term High heat insulating box 700, refrigerator 1.
In addition, Vacuumed insulation panel 400 sometimes gas (air etc.) around absorb due to cause internal vacuum degree to decline, Thermal conductivity deteriorates, but by being configured to the spacer of the resins such as EPS pasting the ground such as outer container 710 in hard polyurethane foams Interior embedded Vacuumed insulation panel 400, it is possible to reduce the amount of the gas (air etc.) around Vacuumed insulation panel 400, therefore can To inhibit Vacuumed insulation panel 400 to absorb the gas (air etc.) of surrounding, the vacuum caused by the reduction of vacuum degree can be inhibited The deterioration of thermal insulation barriers 400 can maintain high heat-proof quality for a long time, and can provide the high heat insulating box 700 of reliability, refrigerator 1, equipment etc..
Especially, in the heat insulating box of present embodiment 700, hard polyurethane foams are existing heat-insulated using density ratio Hard polyurethane foams used in babinet it is high (density be more than 60kg/m3), therefore the bubble in hard polyurethane foams The increased amount of density can correspondingly be reduced, it is possible to reduce the amount (air capacity) of the gas in bubble.Therefore, so that Vacuumed insulation panel When the mode either covered is buried around 400 by hard polyurethane foams being filled or configure, it is possible to reduce vacuum every The amount of gas (air etc.) around warmware 400, therefore the reduction of the vacuum degree of Vacuumed insulation panel 400 can be inhibited (density of polyurethane is bigger, and the gap number in polyurethane is fewer, and the air capacity in polyurethane is fewer).Especially in polyurethane When thinner thickness (when being, for example, 11mm or less), Vacuumed insulation panel 400 is easy to make the gases such as the air waited around polyurethane Into, therefore increase the density of polyurethane to reduce the gas flow around Vacuumed insulation panel 400 for Vacuumed insulation panel 400 The effect of degradation inhibiting is larger.Therefore, the deterioration of Vacuumed insulation panel 400 can be further suppressed, reliability can be provided for a long term High heat insulating box 700, refrigerator 1, equipment.
In addition, in the present embodiment for it will condense 725 heat insulating box 700 that is configured in space 315 of piping into Go explanation, but can certainly be in hard in the heat insulating box 700 that condensation piping 725 is not configured in space 315 Vacuumed insulation panel 400 is buried in polyurethane foam.The amount of the gas around Vacuumed insulation panel 400 can be reduced, therefore It can inhibit the deterioration of Vacuumed insulation panel 400, the high heat insulating box 700 of reliability can be provided for a long term.
Here, not forming orbit portion (track or recess portion of the drawer of drawer type storeroom etc.) 755 in interior case 750 The case where heat insulating box 700 of composition, refrigerator 1 etc., interior case 750 are to be easy to directly paste vacuum using bonding agent or double faced adhesive tape etc. When the shape of thermal insulation barriers 400, all or part of of Vacuumed insulation panel 400 can also be configured at 750 side of interior case.
Here, Vacuumed insulation panel 400 is being adhered directly onto by hot melt adhesive or double faced adhesive tape etc. as shown in the embodiment In the case of the heat insulating box 700 of the composition of 750 side of interior case, it can be provided energy saving and stored up with lesser amount of Vacuumed insulation panel 400 Hide the internal volume efficiency of the room heat insulating box 700 better than the prior art, refrigerator 1.That is, substantially rectangular parallelepiped or cylindrical shape In the case of heat insulating box 700, the surface area of case 750 is big in the surface area ratio of outer container 710, therefore is pasting Vacuumed insulation panel When 400, the Vacuumed insulation panel 400 for being sticked to 750 surface of interior case is fewer than the Vacuumed insulation panel 400 for being sticked to 710 surface of outer container, therefore energy It is enough to obtain inexpensive and good heat-proof quality heat insulating box, refrigerator, showcase, hot water supply device, equipment.In addition, for example pasting When the Vacuumed insulation panel 400 of same size, in the corner of the heat insulating box 700 of rectangular-shape (such as heat insulating box 700 The corner or top surface of the interconnecting piece at the back side and side and the corner etc. of the corner of side or top surface and the back side), corner portion (such as the Vacuumed insulation panel 400 of top surface and adjacent side is true in gap between the Vacuumed insulation panel 400 of wall surface adjacent to each other Gap between empty thermal insulation barriers 400 or distance), when Vacuumed insulation panel 400 is configured at 710 side of outer container, than by vacuum every Warmware 400 is configured at big when interior 750 side of case.That is, by the way that Vacuumed insulation panel 400 is configured at interior case 750, and by same size Vacuumed insulation panel 400 is compared when being configured at outer container 710, can reduce being formed between adjacent Vacuumed insulation panel 400 Gap makes the heat waste caused by heat leak correspondingly reduce the amount of gap shrinks, is capable of providing the good heat insulating box of heat-insulating efficiency 700, refrigerator 1, hot water supply device, showcase, equipment.
In addition, the heat insulating box 700 of present embodiment has for being formed in zonings such as inner utilization partition walls 24 Multiple storerooms 2,3,4,5,6 the shutter door of radial type or drawer type that is opened and closed of opening portion.The door has by example The profile parts (outside plate) constituted such as metal and the inner part (inner panel) that is made of such as resin.Also, it is being formed in profile (filling) is configured in door inner space between component and inner part hard polyurethane foams and Vacuumed insulation panel 400.Door The following technological thought that is also based on illustrated by present embodiment and formed：By Vacuumed insulation panel filling out relative to heat insulating box The rate of filling is set in preset range and has the overwhelming majority of heat insulating function by Vacuumed insulation panel 400.Make the vacuum of an inner space The filling rate of thermal insulation barriers 400 is 40%~90%, covering rate is 70% or more.
When manufacturing this shutter door, Vacuumed insulation panel 400 is first passed through into the 2nd bonding agent etc. in advance and is adhesively fixed to profile portion The raw material of liquid hard polyurethane foams is injected the space between Vacuumed insulation panel and inner part, outer part by part Space between inner part, in a manner of so that profile parts, Vacuumed insulation panel 400, inner part is integrally formed into Row foaming, so as to hard polyurethane foams of the filling as foaming heat insulation part in door inner space.At this point, hard polyurethane Can be 1mm or more preferably 3mm or more and 11mm as long as the thickness of ester foam is also with the intensity as bonding agent (preferably smaller than 10mm, more preferable 6mm or less) below.
In addition, for shutter door, exists and be used to support containing box (storage box body 520) in the installation of storeroom 2,3,4,5,6 Frame either door storage portion or shelf 80 etc. situation, needed the fixing screws of frame, door storage portion to exist Fixed component, shelf 80 installing component etc. using the secure components such as screw, fixed component, holding member and fasten or keep To shutter door inside (case on the inside of) the case where.In this case, there are secure component, fixed component, holding members into door The situation that portion space protrudes, if being contacted with Vacuumed insulation panel 400, it is possible to the outsourcing material of Vacuumed insulation panel can be damaged, therefore It is preferred that in the inside of shutter door thickness configuration or the filled polyurethane foam of Vacuumed insulation panel 400 will not be damaged.However, simultaneously Do not need to be installed on installation fitting (such as secure component, fixed component, the guarantor of (inboard side) on the inside of the storeroom of shutter door especially Hold component etc.) when, Vacuumed insulation panel 400 can also be pasted inner panel.In addition, avoiding installation fitting setting Vacuumed insulation panel When, Vacuumed insulation panel can also be pasted inner panel.
In addition, with profile parts (outside plate) and inner part (inner panel), be formed in profile parts and inner part Between door inner space configuration Vacuumed insulation panel 400, filled out between profile parts or inner part and Vacuumed insulation panel 400 In the case of useing the hard polyurethane foams for foaming heat insulation part as, if the density of foaming heat insulation part is made to be more than 60kg/m3, then right It is used to support the holding intensity or fixed strong of fixed component i.e. screw that the frame of containing box (storage box body 520) is fixed etc. Degree is improved, therefore even if being difficult to deform if box body 520 stores weight door, can steadily carry out going out for box body 520 Enter, the high refrigerator of reliability, equipment can be obtained.In addition, for fixing fixed component i.e. screw of the other components such as handle etc. Holding intensity or fixing intensity be improved, therefore the doors installing component such as handle of other component will be used as to be installed on door When, door installing component is improved to the installation strength of door, therefore door is difficult to deform, and can steadily carry out the opening and closing of door, energy Enough obtain the high refrigerator of reliability, equipment.If in addition, making between profile parts or inner part and Vacuumed insulation panel 400 Hard polyurethane foams as foaming heat insulation part are more than 60kg/m3, then the Deflection Modulus of Elasticity of foaming heat insulation part be improved, The intensity of door is also improved.
Here, Vacuumed insulation panel 400 can be configured at all shutter doors or a part of shutter door.For example, in outer gas and When the temperature difference of (such as in storeroom) is smaller in heat insulating box 700 (such as the refrigerating temperature zones such as refrigerating chamber 2, vegetable compartment 5 Storeroom), though by Vacuumed insulation panel 400 be configured at shutter door heat-proof quality improvement effect if it is smaller.In this case, Even if Vacuumed insulation panel 400 is not configured to shutter door can also ensure that sufficient heat-proof quality.Vacuumed insulation panel 400 is in outer gas When bigger with the temperature difference of (such as in storeroom) in heat insulating box 700 (such as ice-making compartment 3, switch room 4, freezing chamber 6 etc. are cold Freeze the storeroom of temperature band), if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality improves is larger.Cause This, the feelings of the storeroom of the bigger cryogenic temperature band of the temperature difference of (such as in storeroom) in outer gas and heat insulating box 700 Under condition, by the way that Vacuumed insulation panel 400 is configured at shutter door, it can be ensured that sufficient heat-proof quality.
More than, in the heat insulating box 700 either in refrigerator 1 or equipment of present embodiment, relative to will be in 710 He of outer container The spatial volume of the inner space inner spaces Ji Men in the space 315 and shutter door formed between interior case 750 altogether, vacuum every The filling rate of volume ratio, that is, Vacuumed insulation panel 400 shared by warmware 400 within a predetermined range (such as 40% or more 80% Below).Therefore, wall thickness (such as the distance between outer container 710 and interior case 750 and the shutter door of heat insulating box 700 can be made Thickness) it is thinner than the prior art, therefore it is capable of providing energy saving and the indoor internal volume excellent in efficiency of storage heat insulating box 700, refrigerator 1, equipment.Therefore, even if not changing the appearance and size of heat insulating box 700 or refrigerator 1, the indoor internal volume of storage can also be made It is bigger than existing, therefore the storage item that the inside that can increase heat insulating box 700 compared with prior art can store.Therefore, may be used To provide heat insulating box 700 more energy saving than the prior art and that heat-proof quality is good, commodity value is high, refrigerator 1, hot water supply device, display Cabinet, equipment.
In addition, by the filling rate of the Vacuumed insulation panel 400 in increase space 315, the rigid polyurethane foam in space 315 The filling rate of foam reduces.In the heat insulating box 700 of present embodiment, keep the density ratio prior art of hard polyurethane foams big (it is greater than 60kg/m3), it is harder than used in existing heat insulating box to make the Deflection Modulus of Elasticity of hard polyurethane foams The big 15.0MPa or more of the Deflection Modulus of Elasticity (about 6MPa~10MPa) of matter polyurethane foam.Therefore, present embodiment every Hot tank body 700 can also inhibit the strength reduction caused by the reduction of the filling rate of hard polyurethane foams, and hot box is not present Body 700 because can not be resistant to caused by reserve storage space or the weight of the indoor storage item of storage or shutter door it is crooked due to become The problems such as shape, can obtain the high heat insulating box 700 of reliability, refrigerator 1, equipment.
Therefore, in the refrigerator of present embodiment 1 or have in the equipment of the heat insulating box 700 with Vacuumed insulation panel 400, Can inhibit the phenomenon that heat insulating box 700 is crooked and make shutter door tilt etc. shutter doors can not smooth opening and closing, furthermore, it is possible to inhibit The deterioration of the appearance caused by deformation.Furthermore, it is possible to prevent the gasket of shutter door and the opening portion for sealing heat insulating box Contact surface (sealing surface) position relationship deviate and generate gap to make the indoor air of storage (be cold in the case of refrigerator Gas) the case where being flowed out to outside heat insulating box.Inhibit heat insulating box 700 largely using Vacuumed insulation panel 400 as a result, Reduced performance, reliability reduce, have excellent heat-proof quality, therefore can obtain energy saving and high reliability refrigerator or Heat insulating box with Vacuumed insulation panel has the equipment of Vacuumed insulation panel, has the equipment of heat insulating box.
Here, being the length in the height over width direction of upper and lower directions is big when heat insulating box 700 is as refrigerator When elongated rectangular shape, compared to the partition wall 24 etc. between the bottom surface sections 780 of approximate horizontal configuration, top 740, storeroom, The side wall 790 that substantially vertically configures, back face wall 730 are in elongated shape, therefore rigidity is weak and be easily deformed.Therefore, pass through As in this embodiment within a predetermined range by the filling rate of Vacuumed insulation panel 400, covering rate setting, hot box can be improved The intensity (rigidity) of body 700.In addition, babinet intensity can also be improved by the way that protrusion 450 or protrusion 910 is arranged.In addition, setting It is set to the one end for making protrusion 450 and is configured at the Vacuumed insulation panel 400 of recess portion 440 or second recesses 441 with predetermined length X weights It is folded, and the other end is connected to side surface part 790, so as to so that Vacuumed insulation panel 400 via hard polyurethane foams and protrusion 450 is integrally formed, furthermore, it is possible to keep Vacuumed insulation panel 400 integrally formed via hard polyurethane foams and side wall 790, therefore The intensity of babinet 700 can be improved.
Figure 21 is to indicate Vacuumed insulation panel 400 relative to the side surface part 790 of heat insulating box 700 and the surface area institute of back part The figure of the area ratio (side back face covering rate) accounted for and the relationship of box deformation amount, is result of calculation.About the strong of heat insulating box Degree, side wall 790, back face wall 730 shape be elongated oblong-shaped, with top wall 740, underside wall 780, partition wall 24 etc. Substantially square shape compared to rigidity it is weaker, therefore by by the side back face covering rate of Vacuumed insulation panel 400 be set as predetermined value with On, babinet intensity can be improved.Here, to Vacuumed insulation panel 400 relative to shared by side wall 790 and the surface area of back face wall 730 Area ratio (side back face covering rate) and the relationship of babinet intensity illustrate.
In figure 21, horizontal axis indicates side wall 790 and back face wall 730 of the Vacuumed insulation panel 400 relative to heat insulating box 700 Area ratio (side back face covering rate) shared by surface area, the longitudinal axis indicate the deflection of babinet.Here, set the density of polyurethane as 60kg/m3, Vacuumed insulation panel 400 filling rate when be 40%, laterodorsal area ratio (side back face covering rate) being 50% Box deformation amount is 1.The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 used in calculating is 20MPa, based on the true of actual use The measurement result of the Deflection Modulus of Elasticity of empty thermal insulation barriers, (about using the Deflection Modulus of Elasticity than existing hard polyurethane foams 6MPa~10MPa) big component.Here, when changing area ratio (side back face covering rate), the filling rate of Vacuumed insulation panel is solid Be set to 40%, if therefore the area ratio (side back face covering rate) of Vacuumed insulation panel increase, the thickness of Vacuumed insulation panel becomes smaller.
In addition, as an example of refrigerator 1 for calculating, it is assumed that 4 or more (such as 4 either 5 or 6 specifications), interior Volume is 500L grades, consumption electric power is about 40W refrigerators below.Include the distance of the plate thickness between outer container 710 and interior case 750 (wall thickness) average out to 30mm, it is assumed that outer container 710, interior case 750 plate thickness be respectively 1mm, it is (in wall thick to the thickness in space 315 Degree) it is 28mm.The density of hard polyurethane foams is 60kg/m3, Vacuumed insulation panel 400 thermal conductivity be 0.0021 (W/m K), the thermal conductivity of hard polyurethane foams be 0.019 (W/mK), Vacuumed insulation panel 400 compared with hard polyurethane foams every Good in thermal property about 10 times or so.
In figure 21, horizontal axis indicates Vacuumed insulation panel 400 relative to shared by side walls and back face wall surface area altogether Area ratio (laterodorsal Vacuumed insulation panel covering rate), the longitudinal axis expression heat insulating box 700 with shutter door is applied with Box deformation amount (amount of inclining of babinet) when scheduled load.Here, the deflection of babinet is indicated in distance such as hot box The height and position of the upper surface of side wall of side of body about 1/4 or so (laterally, observes front openings in front in a generally horizontal direction It is left and right directions when portion) deflection of the left and right directions of the sidewall upper of heat insulating box when being applied with scheduled load.
In figure 21 it is found that the area ratio of Vacuumed insulation panel 400 is bigger, box deformation amount is smaller.Make side/back side When area ratio (laterodorsal Vacuumed insulation panel covering rate) is 70% or more, the change rate of box deformation amount becomes smaller.That is, arriving side The area ratio at face/back side be 70% or so until, if area ratio becomes larger, box deformation amount drastically becomes smaller, but when side/ When the area ratio at the back side becomes 70% or more, even if area ratio becomes larger, box deformation amount hardly happens variation.Therefore, When the area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side is 70% or more, the reduction of the deflection of babinet Ratio is minimum, even if the side back face area ratio of Vacuumed insulation panel hardly happens variation if increasing box deformation amount.This is recognized For be due to, Vacuumed insulation panel laterodorsal area ratio for babinet intensity influence degree substantially close to saturation.
Here, making the filling rate of Vacuumed insulation panel be fixed as 40% to calculate, if therefore increasing matching for Vacuumed insulation panel 400 Area is set, then the thickness of Vacuumed insulation panel 400 is thinning.Area ratio to side/back side of Vacuumed insulation panel is 70% or so Until, if increase side/back side area ratio, with the thickness of Vacuumed insulation panel it is thinning caused by box deformation increase Amount is compared, the decrement of the box deformation caused by the intensity raising of the babinet caused by the configuration area of Vacuumed insulation panel becomes larger Bigger, therefore the rigidity of babinet improves, the deflection of babinet is reduced.But the area ratio at side/back side of Vacuumed insulation panel When more than about 70%, the increase of the box deformation caused by the strength reduction of babinet caused by the thickness of Vacuumed insulation panel is thinning The decrement of box deformation caused by amount and the raising of the intensity of the babinet caused by the configuration area of Vacuumed insulation panel becomes larger is The reduction degree of same degree, the deflection of babinet becomes smaller.
In addition, keeping the thickness of Vacuumed insulation panel thinning by increasing configuration area ratio (covering rate) of Vacuumed insulation panel When, the thickness of polyurethane foam thickens.Until configuration area ratio is 70% or so, the thickness of Vacuumed insulation panel is predetermined thickness Degree or more, therefore the decrement of the thickness compared to Vacuumed insulation panel, the shadow of the incrementss of area ratio to the intensity of heat insulating box Bigger is rung, box deformation amount is reduced, if but further increasing the configuration area ratio of Vacuumed insulation panel, the thickness of Vacuumed insulation panel Degree becomes smaller, and the thickness of polyurethane becomes larger, thus the configuration area ratio of the incrementss of the thickness of polyurethane and Vacuumed insulation panel Influence of the incrementss to the intensity of heat insulating box becomes same, and the reduction degree of box deformation amount becomes smaller.
Therefore, if the area ratio (side back face covering rate) at side/back side of Vacuumed insulation panel 400 is set as predetermined value (70%) more than, so that it may to obtain babinet intensity, therefore the high babinet of reliability can be obtained.If in addition, by Vacuumed insulation panel The area ratio at side/back side be set as predetermined value (70%) or more, then hardly happen variation as box deformation amount Region, therefore even if the configuration area of Vacuumed insulation panel hardly happens variation, therefore energy if generating the deflection of uneven babinet Enough obtain high intensity, the heat insulating box that aesthetic appearance is good, reliability is high, refrigerator, showcase, equipment.If making Vacuumed insulation panel 400 Covering rate is predetermined value or more (60% or more) and the area ratio at side/back side of Vacuumed insulation panel 400 is set as the 2nd More than predetermined value (70%), then heat-proof quality improves, and can reduce box deformation amount, therefore can obtain heat-proof quality Greatly, reliability height and energy-efficient refrigerator, showcase, equipment.
If here, making the thickness of Vacuumed insulation panel fix and expanding the configuration area of Vacuumed insulation panel 400, vacuum heat-insulation The covering rate of part, filling rate can increase, if but the filling rate of Vacuumed insulation panel 400 increase, cost increases, therefore does not change Become filling rate and cost is relatively low when by increasing intensity of the covering rate to improve heat insulating box 700, and can increase vacuum every The configuration area of warmware, therefore heat-insulating efficiency improves.Therefore, it is 40% or more by making the filling rate of Vacuumed insulation panel 400, makes The area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side is 70% or more, can be with low-cost high-efficiency true Protect the intensity of heat insulating box.Therefore, if by area ratio (the laterodorsal Vacuumed insulation panel at side/back side of Vacuumed insulation panel Covering rate) be set as the 2nd predetermined value (be the reduction ratio of the deflection of heat insulating box become smaller area ratio, be, for example, 70% Left and right) more than, so that it may the wall thickness (thickness that polyurethane is thinned) of heat insulating box 700 is thinned, increases the internal volume of storeroom.Side The configuration area (laterodorsal Vacuumed insulation panel covering rate) of wall 790 and the Vacuumed insulation panel of back face wall 730 400 is bigger, heat-insulated The deflection of babinet 700 is smaller, therefore can increase the intensity of heat insulating box 700, can provide high intensity and heat-proof quality is good Heat insulating box 700, refrigerator 1, the equipment for having heat insulating box.
(polyurethane physical property)
Here, physical property, the characteristic of the hard polyurethane foams to being filled in heat insulating box 700 illustrate.Hard polyurethane Ester foam can provide the intensity stabilization after foaming, the heat insulating box that appearance is good, quality is high by increasing free foaming density 700。
Here, free foaming density refers to, not makes polyurethane foam in the closed space such as babinet but opening Container in etc. hard polyurethane foams when making polyurethane foam under opening states density.And in fact, due to polyurethane It foams, expand in closed narrow space in heat insulating box 700, therefore the narrow space closed in heat insulating box 700 etc. The density of the polyurethane of interior foaming, expansion, the free foaming density of the polyurethane than foaming, expanding in the open state are big.
Density by improving the hard polyurethane foams after foaming can increase bending resistance springform as illustrated in figure 16 Amount, but when making polyurethane stock solution flow directly into heat insulating box 700 to be filled to increase density, for the foaming used now The small polyurethane of multiplying power, free foaming density are small to 26~28kg/m3, expansion ratio is small, if therefore polyurethane flowing part Flow path thickness that there are sizes is not, then foaming degree is uneven, inlet 703,704 near and terminal part (separate inlet Position) polyurethane density easy tos produce unevenness, it is difficult to obtain stable intensity.
In the present embodiment, by using free foaming density than existing (for example, about 25~28kg/m3) big hard Polyurethane foam (such as free foaming density is about 30~45kg/m3), even if the flow path thickness in the part of polyurethane flowing It is not that there are a little sizes, also due to expansion ratio is big and can steadily foam, can reduce the unevenness of the density after foaming. Thus, it is easy to keep the density of the polyurethane after foaming generally uniform.
Foaming body as hard polyurethane foams has bubble in inside, and density is smaller, and bubble is more, heat-insulated effect Fruit is higher.Therefore, heat insulating box 700 makes the density after the foaming of the hard polyurethane foams used be in the prior art About 25~28kg/m3Small density hard polyurethane foams.Want to make bending resistance springform using the existing polyurethane foam It is true removing when amount is intensity of the 15MPa or more to ensure heat insulating box 700, such as in the case that thickness is 28mm in wall The thickness of polyurethane after the thickness of empty thermal insulation barriers is in the heat insulating box of 8mm, it is necessary to be injected, the lucky of packing ratio polyurethane is filled out Charge (is gathering when will not apply unreasonable load etc. into the babinet as object and fill hard polyurethane foams just Urethane amount, the density after foaming are easy to become uniform) polyurethane mostly, density easy tos produce unevenness.
In turn, the polyurethane due to that must inject, more than the lucky loading of packing ratio, it is therefore desirable to add when polyurethane injects Pressure extends the filling time, to which polyurethane is from the gaps such as the joint portion of heat insulating box 700, the profile of shutter door (such as outer container 710 and interior case 750 joint portion) leak out, can not inject and (can not fill) needed for predetermined amount polyurethane, it is difficult to ensure filling The density of hard polyurethane foams after to babinet is than predetermined value (such as 60kg/mm3) big density.If in addition, polyurethane It is leaked out from the profile of babinet, it is necessary to remove the operation of the polyurethane of leakage, activity duration or built-up time are needed to increase, be led Cost is caused to increase, aesthetic appearance reduces.Therefore, the density for being filled into the polyurethane after heat insulating box in the prior art is less than 60kg/ m3, about 25~30kg/m3, up to about 55kg/m3Below.
Here, in the present embodiment, have studied by reduce the amount of expanded material for including in polyurethane stock solution etc. come Increase free foaming density.Such as (it is thick to remove the polyurethane flow path after the thickness of Vacuumed insulation panel in the thickness of polyurethane for 8mm Degree is about 8mm) heat insulating box 700 in, by the way that free foaming density is set as predetermined value (30kg/m3Above, preferably 35kg/m3More than), can make under lucky loading density (do not apply the ground such as unreasonable load be filled into it is poly- after babinet The density of urethane) compare 60kg/m3Greatly, it is 15MPa or more that can make the Deflection Modulus of Elasticity of hard polyurethane foams.Therefore, may be used To eliminate the density unevenness of polyurethane, the heat insulating box that polyurethane leaks out etc the problem of, can obtain that reliability is high, high intensity Heat insulating box 700, refrigerator 1, showcase, the equipment for having heat insulating box.
Here, worrying that the free foaming density of hard polyaminoester is bigger than predetermined value, it is close to increase the polyurethane after foaming because making Influence to heat-proof quality is spent, but as illustrated by Figure 17~Figure 21, such as by the position that configures of Vacuumed insulation panel 400 The thickness of polyurethane is set as predetermined value or less (11mm or less or 6mm or less) or by thickness in thickness/wall of polyurethane Be set as predetermined value (0.3) below or by the filling rate of Vacuumed insulation panel 400 be set as preset range (40% or more 90% with Under) when, the influence to the heat-proof quality of heat insulating box can be reduced (to the heat-insulated of the heat insulating box of heat insulating box 700, shutter door The influence of performance).In addition, make polyurethane thickness be 11mm or less when, by make free foaming density be predetermined value (such as 35kg/m3) more than, it can be set to the lucky loading (lucky loading can be adjusted) for not causing polyurethane to leak out.
The heat insulating box 700 of present embodiment can make the wall ratio of heat insulating box 700 existing thin, furthermore it is ensured that in advance Fixed intensity, in filling polyurethane, polyurethane is also difficult to leak out from profile, can meet required quality, can provide section The heat insulating box 700 of energy, internal volume excellent in efficiency.Either refrigerator 1 or has heat insulating box that is, not changing heat insulating box 700 The appearance and size of equipment can just make the reserve of heat insulating box store volume (such as in the case of refrigerator for case internal volume or Reservoir volume) it is bigger than existing, the storage item that the inside of heat insulating box 700 can store can be increased compared with prior art.Cause This, can obtain user is easy to use, thermal insulation is good, high intensity and reliability are high heat insulating box 700 either refrigerator 1 or tool The equipment of standby heat insulating box.In addition, by the storage volume settings of indoor (in storeroom) at it is same with the prior art when, can make Appearance and size correspondingly reduces the amount that wall thickness can reduce.
Here, refrigerator 1 has for the cooling air supplied to multiple storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5 The cooling device of (cold air).The cooling device is (swollen by compressor 12, refrigerant piping (such as condensation piping 725), decompressor Swollen valve, capillary etc.), the compositions such as cooler 13, form freeze cycle.Constitute the compressor in the inscape of the freeze cycle 12, decompressor is set to the machinery in back underside (can also be on the upside of the back side) formation for the heat insulating box 700 for forming refrigerator 1 In the 1A of room.Condensation piping 725 is set to such as side wall 790 either back face wall 730 or the top wall 740 of heat insulating box 700.Pass through The fan grill etc. of reserve storage space is formed at the back side of storeroom, overleaf the storeroom side of wall 730 is equipped with and interior case The back side cover of 750 seperated components, cooler 13 are cold set on being formed between the cover member of the back sides such as interior case 750 and fan grill But in device room 131.In addition, being additionally provided in the cooler room 131 for sending the air cooled by cooler 13 (cold air) Circulating cold air fan 14 of the wind to each storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartments 5.In addition, in heat insulating box 700 Top wall 740 either back face wall 730 top (or substantial middle height and position of back face wall 730) be equipped with control base board room 31, control device 30 is equipped in control base board room 31, which carries out control compressor 12 or circulating cold air wind Motion control or the temperature inside the box control of the rotating speed of fan 14 etc. etc..
In the refrigerator 1 constituted in this way, by the gas system for the high temperature and pressure that the compressor 12 being configured in the 1A of Machine Room is sent out Cryogen, refrigerant piping (such as condensation piping) 725 by by be condensed, become the liquid refrigerant of cryogenic high pressure, low temperature The liquid refrigerant of high pressure is depressurized into the gas-liquid two-phase refrigerant of low-temp low-pressure by decompressor, when reaching cooler 13, is become Such as -20 DEG C of low temperature below.Air in the gas-liquid two-phase refrigerant cooling cooler room 131 of the low-temp low-pressure, and should Air after cooling is supplied to each storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5 by circulating cold air fan 14, to The storerooms (or the storage item stored in these storerooms) such as cooling refrigerating chamber 2, freezing chamber 6, vegetable compartment 5.On the other hand, cold But the gas-liquid two-phase refrigerant of the low-temp low-pressure of the air in cooler room 131, by the air heating in cooler room 131 Evaporation, becomes the gas shape refrigerant of low pressure and is inhaled into compressor 12 once again and is compressed.
As described above, in the refrigerator 1 of present embodiment, make Vacuumed insulation panel 400 relative in outer container 710 and interior case Ratio i.e. vacuum shared by total volume of the internal capacity of the door inner space in the space 315 and shutter door that are formed between 750 The filling rate of thermal insulation barriers is predetermined value (such as 40%~80%).Therefore, even if thickness is (outside such as in the wall of heat insulating box 700 The thickness of distance (thickness) or shutter door between case 710 and interior case 750) it is thinner than the prior art, it can also ensure that thermal insulation Energy.Therefore, in the refrigerator of present embodiment 1, the heat-proof quality of heat insulating box 700 is improved, thus multiple storerooms 2, 3, the cold air in 4,5,6, storage item are not easy to warm, therefore can shorten the duration of runs for cooling compressor 12 or subtract The air quantity of small fan.Therefore, it is possible to the air quantity of the required air (cold air) of the cooling in storeroom 2,3,4,5,6 is inhibited compared with It is small, the rotating speed of compressor 12 can be reduced or extend operating OFF time, therefore energy-efficient operating can be carried out.Therefore, in this reality It, can be more energy saving than existing in the refrigerator 1 for applying mode.It can expand compared with prior art in addition, refrigerator 1 does not change appearance and size Big reservoir volume (case internal volume), can increase the storage item that can be stored in storeroom, therefore can obtain compared with prior art Obtain refrigerator easy to use, equipment.
, can in addition, the substantial middle position that if upper and lower directions will be configured at the maximum freezing chamber of the temperature difference of outer gas 6 It is enough inhibit from above and under the heat from outer gas that enters towards freezing chamber 6, therefore heat can be made from outer gas intrusion freezing chamber 6 Hot entering surface is 4 faces (shutter door of front, left side, right side, this 4 face of the back side).Thus, it is possible to obtain energy-efficient refrigerator 1.
In addition, according to the present embodiment, making the bending resistance for being filled in the hard polyurethane foams in space 315 and door inner space Elasticity modulus is 15.0MPa or more, therefore the babinet intensity of heat insulating box 700 can meet scheduled intensity, so as to press down Heat insulating box 700 processed deforms due to can not be resistant to crooked caused by the weight of storage item.Therefore, heat insulating box 700 can be inhibited Shutter door that is crooked and making front tilts, and can prevent the deterioration of appearance.Furthermore, it is possible to inhibit to shutter door and heat insulating box The position for the seal member being sealed between front openings portion is staggered and generates gap, to make refrigerating chamber 2, freezing chamber 6, vegetable Dish room 5, ice-making compartment 3, the air (cold air) in switch room 4 to heat insulating box 700, refrigerator 1 external the case where leaking out, so as to Enough obtain more energy efficient refrigerator, equipment.
In addition, the distribution of the filling rate about the Vacuumed insulation panel 400 in space 315 or door inner space, it can also According to the temperature difference of outer gas and each storeroom, and changed according to scheduled position in space 315 or door inner space true The filling rate of empty thermal insulation barriers 400.
For example, the freezing chamber 6 (or ice-making compartment 3, switch room 4) as low temperature chamber, stores indoor temperature and outer gas Temperature difference it is maximum.Therefore, can make the left side of heat insulating box 700 in the range opposite with freezing chamber 6, right side, The filling rate ratio of the Vacuumed insulation panel 400 of the back side and front (shutter door) and other storerooms (such as the refrigeration as hot room Room 2, vegetable compartment 5) opposite range wall surface (such as left side, right side, the back side and front (shutter door)) it is big by (such as 60% More than).With this configuration, the heat intrusion to the i.e. freezing chamber 6 of the minimum low temperature chamber of temperature can be inhibited, can be obtained more energy efficient Refrigerator 1, equipment.
For example, when outside air temperature is such as 30 DEG C, become such as 40 DEG C or more in the 1A of Machine Room.The temperature of control base board room 31 Degree also rises to such as 40 DEG C or more.That is, the wall between Machine Room 1A and control base board room 31 and the storeroom of opposite position Face, partition wall 24 compare wall surface, the partition wall 24 of other parts, and indoor temperature difference is larger with storing.Therefore, heat is easy to invade Enter the storeroom configured near Machine Room 1A, control base board room 31.Therefore, Machine Room 1A or control base board room are being configured at Wall surface, partition wall 24 between 31 and storeroom can make the filling rate of Vacuumed insulation panel 400 than other wall surfaces, partition wall 24 It is big to improve heat-proof quality.Such as in wall surface, the partition wall being configured between Machine Room 1A or control base board room 31 and storeroom 24, it is 60% or more (the side back face covering rate of Vacuumed insulation panel 400 to be made to be 70% that can make the filling rate of Vacuumed insulation panel 400 More than), and make other wall surfaces, partition wall 24 Vacuumed insulation panel 400 filling rate be 40% or more (90% or less).It is logical Composition in this way is crossed, heat can be inhibited to be invaded from the high Machine Room 1A of temperature, control base board room to neighbouring storeroom, ice can be made The more energy-saving of case 1.
The heat insulating box 700 of present embodiment for example can be used for heating the heating device of water and have storage and stay and added by this The heat accumulation water installations of the tank of the warmed-up water of thermal.By the inside batch tank in heat insulating box 700, shape ruler can be passed through It is very little than existing small heat insulating box 700 that tank is more heat-insulated, water storage device space saving can be made.As long as in addition, present embodiment Be with the thermal wall with Vacuumed insulation panel equipment (such as refrigerator, showcase, refrigerator, hot-water supply, hot shot water machine, Air-conditioning device etc.) it can apply.
In embodiments of the present invention, it is not necessary that bumps etc. are arranged in Vacuumed insulation panel 400, without make enclose outer packaging material Core material in material is along the shape of the concaveconvex shape of outsourcing material, therefore Vacuumed insulation panel 400 can use flat object Body, so, core material can use inorfils, the organic fibers such as glass fibre etc. without using the shot-like particle with mobility Fiber-like core material, and the complicated processing of bumps etc. need not be set in outsourcing material, so as to obtain low cost, treatability Well, the high heat insulating box of heat-proof quality, refrigerator, equipment.
Here, in the present embodiment, the 3rd sandwiched component can be identical as the 1st sandwiched component.In addition, the 2nd sandwiched component It can also be identical as the 1st sandwiched component.
(effect that embodiment plays)
