Summary of the invention

The problem that invention is to be solved

Vacuumed insulation panel is compared the heat-proof quality of existing hard polyurethane foams and is had such as 6 times Above heat-proof quality.Therefore, from the angle etc. of energy-saving, it is being formed at outer container and interior In space between case, except configuration hard polyurethane foams, also configure that Vacuumed insulation panel.And And, along with the raising of the requirement of energy-saving in recent years, heat insulation as described in such as patent documentation 1 Casing is such, and the usage amount of the Vacuumed insulation panel being configured at heat insulating box also increases.

On the other hand, in recent years for heat insulating box, from space saving, the Large Copacity of internal volume The angle changed is set out, and also requires to reduce space, the i.e. hot box being formed between outer container and interior case The wall thickness of body.But, existing heat insulating box is to be made based on following technological thought: Hard polyurethane foams mainly undertakes heat insulating function, Vacuumed insulation panel auxiliary hard polyurethane foams Heat insulating function.Here, existing heat insulating box by by hard polyurethane foams with predetermined Density is filled into the space between interior case and outer container and obtains casing intensity, but to reduce poly-ammonia When the thickness of ester is to reduce the thickness of wall, the thickness of polyurethane diminishes, and the density of polyurethane increases Adding, heat-proof quality declines, therefore, it is difficult to the casing intensity needed for meeting heat-proof quality and obtaining.

That is, have in the equipment of Vacuumed insulation panel at existing heat insulating box or refrigerator etc., pass through Hard polyurethane foams guarantees wall and the heat-proof quality of casing and casing, the intensity of wall, Reduce the thickness of hard polyurethane foams to reduce the wall thickness of heat insulating box, then can produce every The problem that the heat-proof quality of hot tank body is not enough or intensity is not enough and is difficult to the minimizing of wall thickness.

Here, in the heat insulating box described in patent documentation 1, the usage amount (quilt of Vacuumed insulation panel Cover rate) increase, the Deflection Modulus of Elasticity of hard polyurethane foams (hard polyurethane foams firm Property) increase, therefore it is also considered as subtracting to a certain extent for the intensity face of heat insulating box Few wall thickness.But, the heat insulating box described in patent documentation 1 is by hard polyurethane foams master Heat insulating function to be undertaken and the technology of heat insulating function of Vacuumed insulation panel auxiliary hard polyurethane foams Thought is made, and hard polyurethane foams mainly undertakes heat insulating function, and Vacuumed insulation panel is auxiliary Help the heat insulating function of hard polyurethane foams, guarantee heat insulating box by hard polyurethane foams Heat-proof quality and the intensity of wall.But, when the thickness of hard polyurethane foams diminishes, close Degree, Deflection Modulus of Elasticity can increase, but thermal insulation deteriorates.Therefore, in order to suppress hard polyurethane The decline of the heat-proof quality of ester foam, be set to make hard polyurethane foams Deflection Modulus of Elasticity, Density is below predetermined value (below Deflection Modulus of Elasticity 10MPa, density 60kg/m³Below). When Deflection Modulus of Elasticity, density exceed predetermined value, although casing intensity is met, but heat insulation Penalty, thus be difficult with.Therefore, the heat insulating box described in patent documentation 1 is in order to really Protect both casing, the intensity of wall and heat-proof quality, therefore, to assure that the thickness of polyurethane exists More than to a certain degree, need to be adjusted to the polyurethane stream thickness at the position of filled polyurethane for this For more than predetermined thickness so that the density after polyurethane foam is below predetermined value (density 60kg/m³Below), thus exist be difficult to reduce wall thickness problem.

Additionally, patent documentation 2 is as the intensity measure of the heat insulating box possessing Vacuumed insulation panel, Employ following Vacuumed insulation panel, interior case, outer container: for the outsourcing material of Vacuumed insulation panel Plastic material etc. is shaped to target shape by vacuum forming, compressed air molding etc., The core that internal filling is granular, thus it is shaped to ensure that the concaveconvex shape of intensity.But, make Interior case, outer container are the convex-concave profile of the concavo-convex basic similar shape of the outsourcing material with Vacuumed insulation panel And embed and make interior case and outer container to have intensity, thus outsourcing material, interior case, the shape of outer container Shape becomes complicated, there is the problems such as cost rising, assembleability deterioration.Additionally, from guaranteeing intensity Angle set out, Vacuumed insulation panel is also required to outsourcing material is shaped to concaveconvex shape, outside inclosure Core in packaging material is also required to be the shape of the concaveconvex shape according to outsourcing material, therefore core Need to use and there is the shot-like particle of mobility, cost liter compared with the fiber-like core such as glass fibre Height, heat-proof quality there is also the probability of variation.Additionally, the indoor (storage in heat insulating box The accommodation space of thing etc.) the back side be concaveconvex shape, complex-shaped, aesthetic appearance be deteriorated.

Here, Vacuumed insulation panel 400 and interior case 750 are via with bonding bonding as main purpose The most bonding direct bonding site of agent (can be the foaming heat insulation part with self-adhesiveness) is i.e. Recess 440, such as relative to the strengthening part sandwiched being filled with the strengthening parts such as hard polyaminoester Position (such as protuberance 450) has the stage portion 776 of the projecting height amount of protuberance 450, recess 440 cave in depth direction (rear side) relative to protuberance 450.Otherwise, as rib The protuberance 450 at part sandwiched position using the amount of stage portion 776 relative to as direct bonding site Recess 440 is prominent to the front side of depth direction.Additionally, Vacuumed insulation panel 400 and interior case 750 The direct bonding site i.e. recess that the bonding agents such as the foaming heat insulation part via self-adhesiveness are the most bonding 440, there is the step that the height (thickness) of cold air wind path 760 is measured, recess 440 is relative to cold Cave in depth direction (rear side) in the front face side end 769 of gas wind path 760.Otherwise, cold The end face 769 of the front face side of gas wind path 760 with the amount of step relative to direct bonding site to entering The front side in deep direction highlights.

As it has been described above, in the present embodiment, being formed by interior case 750 and outer container 710 and Possess between interior case 750 and outer container 710 heat insulating box of Vacuumed insulation panel 400, refrigerator, In the equipment such as cold insulated cabinet, showcase, possess: the back of the body of indoor (such as in storeroom) will be located at The Vacuumed insulation panel 400 in 730 of facing the wall and meditating is bonding by having foaming heat insulation part of self-adhesiveness etc. Agent is adhered directly onto the direct bonding site (for recess 440 in figure) of interior case 750；With in vacuum Between thermal insulation barriers 400 and interior case 750 sandwiched for improve casing intensity as strengthening part The strengthening part sandwiched position (being protuberance 450 in figure) of the thermal insulation barriers 751 such as polyurethane.Here, Vacuumed insulation panel 400 and outer container 710 by PUR or double faced adhesive tape etc. the 2nd bonding agent directly glue Stick together.PUR or double faced adhesive tape etc. the 2nd bonding agent can be pre-coated with or be pasted onto vacuum Thermal insulation barriers 400 side or outer container 710 side, therefore can be thus excellent with the thickness of thinning bonding agent Choosing；But coating inequality may be produced or paste unequal, therefore Vacuumed insulation panel 400 He The foaming heat insulation part with self-adhesiveness is preferably used between interior case 750.

Additionally, in the present embodiment, such as strengthening part sandwiched position (such as protuberance 450) Width with direct bonding site (such as recess 440) the sustained height position in storeroom Direction is arranged, and the strengthening part arranged by the left and right end portions of the width in storeroom is pressed from both sides Position if (such as protuberance 450) and in the way of being clipped by the strengthening part sandwiched position of left and right It is located at the direct bonding site (such as recess 440) between the strengthening part sandwiched position of left and right, And the left and right directions at the storeroom back side forms protuberance 450 (strengthening part sandwiched position), convex Recess 440 (direct bonding site) is formed between portion 450.Here, recess 440 and protuberance 450 From the intensity guaranteeing casing or the angle guaranteeing cold air wind path, preferably in storeroom The most whole altitude range of above-below direction is arranged.

So, with recess 440 position in opposite directions, make Vacuumed insulation panel 400 and outer container 710 directly contact via the 2nd bonding agent or abut, therefore at outer container 710 and vacuum heat-insulation Need not thermal insulation barriers between part 400, storeroom content can be increased compared with during sandwiched thermal insulation barriers Long-pending.Additionally, at direct bonding site (such as recess 440), make Vacuumed insulation panel 400 and interior Case 750 contacts via the foaming binding agent with cementability or abuts.In the present embodiment, At the configuration position (such as recess 440) of Vacuumed insulation panel 400, by Vacuumed insulation panel 400 And there is heat-proof quality and intensity, therefore it is not required between interior case 750 and Vacuumed insulation panel 400 Will with the heat insulation thermal insulation barriers as main purpose, with heat insulation as main purpose during sandwiched thermal insulation barriers Compare and therefore can increase storeroom internal volume with thinning wall thickness.Here, as bonding agent When needing mobility, it is possible to use there is the hard polyurethane foams etc. of self-adhesiveness, with Make it foam after in two-phase state inflow space 315 thus carry out bonding.

In the present embodiment, as the cold air wind that the cold air that cold storage is indoor is blowed Road 760 can utilize recess 440, therefore, it is possible to make the storeroom back of the body that the hands of user is difficult to touch The recess 440 in face is utilized effectively, such that it is able to use the storage in storeroom to hold efficiently Long-pending.Additionally, use the vacuum heat-insulation with predetermined intensity (bending strength, buckling strength) Protuberance 450 also (is preferably able to guarantee to reverse in storeroom by part 400 with predetermined width Intensity, the degree of buckling strength) when above-below direction is arranged continuously, it is possible to obtain heat insulating box 700, the intensity needed for refrigerator 1, and guarantee the curved of torsional strength, fore-and-aft direction or left and right directions Folding intensity, therefore, it is possible to obtain the high heat insulating box 700 of reliability, refrigerator 1.As long as it addition, Intensity needed for being obtained in that heat insulating box 700, refrigerator 1 also guarantees torsional strength, front and back To or the buckling strength of left and right directions, protuberance 450 is without arranging continuously at above-below direction, it is possible to To arrange at one or to arrange many places intermittently.

In the present embodiment, (the width end, left and right end portions side at the back side in storeroom Side) form the protuberance 450 being made up of thermal insulation barriers 701 such as the polyurethane configured along the vertical direction, Therefore casing 700, the torsional strength of refrigerator 1, curved can be improved by forming this protuberance 450 Folding intensity.Therefore, do not have casing 700 or refrigerator 1 deforms and makes to be located at storeroom (example Such as cold room 2) before door of storage room (refrigerating-chamber door 7 of the most rotary (radial type)) Tilt, such as in the case of clamshell doors, a side of the door (7A, 7B) of left and right tilts and causes The situation of dislocation, therefore, it is possible to successfully carry out the opening and closing of door of storage room.Additionally, will not occur The dislocation of the door of storage room of left and right, the most attractive in appearance.Additionally, in the case of drawer type door, no Can make to be located at storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment because casing 700 deforms 5, refrigerating chamber 6 etc.) rail of drawer type box body of inwall (sidewall of left and right) 791,792 Different or inclination about the setting height(from bottom) in road, therefore, it is possible to successfully carry out the discrepancy of box body.

Here, in the present embodiment, Vacuumed insulation panel 400, the poly-ammonia of formation protuberance 450 The thermal insulation barriers such as ester need predetermined intensity, and therefore Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity For thermal insulation barriers use bending resistance elasticity such as the parts of more than 20MPa, the polyurethane of formation protuberance 450 Modulus is more than 13.0MPa (preferably more than 15MPa), density is more than 60kg/m³(excellent Elect 62kg/m as³Parts above).It is strong that the thermal insulation barriers such as polyurethane to be passed through obtain casing Degree and both heat-proof qualities, therefore from the angle guaranteeing casing intensity need to make polyurethane every Warmware increase Deflection Modulus of Elasticity, if but as hard polyaminoester characteristic increase bending resistance springform Amount, then density increases, if density increases, heat-proof quality declines.Therefore, in the feelings of polyurethane Under condition, in order to obtain predetermined heat-proof quality, it is difficult to make Deflection Modulus of Elasticity be about 10MPa Above, therefore, it is impossible to make the thickness of polyurethane be thinner than e.g., from about 15mm.Here, polyurethane Thickness the thinnest, more can reduce the thickness of wall, increase storeroom internal volume, thus preferably. But, in order to reduce wall thickness and during the thickness of thinning polyurethane, the density of polyurethane increases, anti- Curved elastic modelling quantity also increases, therefore, it is possible to increase casing intensity, but heat-proof quality when density increases Can deteriorate, therefore, it is difficult to make the thickness of polyurethane be thinner than predetermined value (such as 15mm).

In the present invention, Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity greatly to more than 20MPa Parts, be therefore configured with the part (casing or wall) of Vacuumed insulation panel 400, can make Vacuumed insulation panel 400 has both heat-proof quality and intensity, even if filling out between outer container and interior case When filling the thermal insulation barriers such as polyurethane, at the position being configured with Vacuumed insulation panel, without by polyurethane Can use as bonding agent as using with the heat insulation thermal insulation barriers as main purpose.Cause This, can using the thermal insulation barriers such as polyurethane as to Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container 710 carry out bonding bonding agent and use, even if therefore reducing poly- The thickness of urethane and to make the heat-proof quality of polyurethane decline the most no problem.Here, it is true by making The covering rate of empty thermal insulation barriers 400 (the configuration area of Vacuumed insulation panel 400 relative to casing 700, The ratio of the surface area of door) or the filling rate (Vacuumed insulation panel 400 of Vacuumed insulation panel 400 V/V relative to shared by the space 315 between outer container 710 and interior case 750) big to pre- More than definite value, even if there is the position not configuring Vacuumed insulation panel 400, it is also possible to guarantee conduct The heat-proof quality of heat insulating box 700, intensity.

Therefore, as shown in the embodiment recess 440 grade outer container 710 and interior case 750 it Between be configured with the position of Vacuumed insulation panel 400, by Vacuumed insulation panel 400, there is casing 700 Intensity and heat-proof quality both time, between Vacuumed insulation panel 400 and outer container 710 or Between Vacuumed insulation panel 400 and interior case 750, can be as with bonding bonding as main purpose Agent uses hard polyurethane foams, therefore can reduce the thickness of polyurethane, can not consider The decline of the heat-proof quality of polyurethane.Therefore, even if because of the thickness of thinning hard polyurethane foams And reduce wall thickness, make the heat-proof quality of hard polyaminoester decline, due to casing heat-proof quality by Vacuumed insulation panel 400 undertakes, the most no problem.Thus, it is possible to by reducing polyurethane Thickness, reduce wall thickness increase storeroom internal volume.Wherein, outer container 710 and vacuum every Any one party between warmware 400 or between interior case 750 and Vacuumed insulation panel 400 uses During 2 bonding agent such as PUR or double faced adhesive tape can thinning wall thickness, therefore, it is possible to increase storeroom Interior volume.

Here, as between Vacuumed insulation panel 400 and outer container 710 or Vacuumed insulation panel The thickness of the hard polyurethane foams when bonding agent used between 400 and interior case 750 uses is During below predetermined value or less than the thickness of Vacuumed insulation panel 400, it is possible to reduce wall thickness, therefore The volume in storeroom can be increased.Here, for Vacuumed insulation panel 400 and outer container 710 it Between or Vacuumed insulation panel 400 and interior case 750 between any one party use with bonding be When the thickness of the hard polyurethane foams of main purpose is less than the thickness of Vacuumed insulation panel 400, can Acquisition can reduce the effect of wall thickness.If hard between Vacuumed insulation panel 400 and outer container 710 Hard polyaminoester between thickness and Vacuumed insulation panel 400 and the interior case 750 of matter polyurethane foam The thickness sum of foam less than the thickness of Vacuumed insulation panel 400, then can reduce wall thickness further, It is thus possible to the volume in increase storeroom.

In the present embodiment, as between Vacuumed insulation panel 400 and outer container 710 or The bonding agent used between Vacuumed insulation panel 400 and interior case 750, uses hard polyurethane foams, And make the thickness of polyurethane the thinnest.But, it is not only Vacuumed insulation panel 400 and outer container 710 Between or Vacuumed insulation panel 400 and interior case 750 between, be not provided with Vacuumed insulation panel 400 And the position (in wall) being only filled with polyurethane can also use identical hard polyurethane foams. It is not provided with Vacuumed insulation panel 400 and is only filled with the position of polyurethane (in such as wall or in protuberance A part) owing to there is not Vacuumed insulation panel 400, such that it is able to make the thickness of hard polyaminoester Degree increases the amount of thickness of Vacuumed insulation panel 400, therefore can also increase the insulating thickness of polyurethane. Therefore, and between Vacuumed insulation panel 400 and outer container 710 or Vacuumed insulation panel 400 and The thickness of the polyurethane filled between interior case 750 is compared, and can increase and there is not Vacuumed insulation panel The thickness of the polyurethane at the position of 400, thus be configured with the position of Vacuumed insulation panel 400 The density of polyurethane is compared, it is possible to reduce the polyurethane at the position not configuring Vacuumed insulation panel 400 Density, therefore do not configure the position of Vacuumed insulation panel 400 polyurethane heat-proof quality improve, May insure that predetermined performance.Additionally, at the position not configuring Vacuumed insulation panel 400, permissible Increasing the thickness of polyurethane, therefore casing intensity also improves.Here, in the present embodiment, In order to meet both casing intensity and heat-proof quality, the covering rate (vacuum of Vacuumed insulation panel 400 The configuration area of thermal insulation barriers 400 is relative to casing 700, the ratio of the surface area of door) or true (Vacuumed insulation panel 400 is relative to outer container 710 and interior case 750 for the filling rate of empty thermal insulation barriers 400 Between the V/V shared by space 315) greatly to more than predetermined value.

In the present embodiment, be there is heat-proof quality, casing by Vacuumed insulation panel 400 strong Degree, therefore can use the thickness of polyurethane thermal insulation barriers reduce and make the intensity of polyurethane thermal insulation barriers For Deflection Modulus of Elasticity greatly to the parts of more than 13.0MPa (preferably more than 15MPa).This Outward, it is possible to use the density of polyurethane thermal insulation barriers is more than 60kg/m³(preferably 62kg/m³With On) parts, therefore can reduce the thickness of polyurethane, it is also possible to reduce heat insulating box 700 Wall thickness.

Wide bandgap semiconductor (such as carborundum SiC, gallium nitride, gallium nitride (GaN) etc.) Following 2 points are included relative to the advantage of silicon (Si) quasiconductor.First advantage is the damage of element Lose little, can high temperature action.The caloric value of Si is many and at about 100 DEG C～200 DEG C of lower semiconductor Performance reduces, dyskinesia, it is therefore desirable to arranges the fin (radiator) of heat transmission and goes forward side by side one Walk and dispel the heat via air, need the storage volume for carrying fin and for the space of heat radiation. In contrast, in the case of wide bandgap semiconductor (such as SiC) switching losses in element is relatively Little, energy-conservation, simultaneously until about the 300 DEG C reductions being all difficult to performance, therefore can Enough uses in the hot environments such as Machine Room 1A.Additionally, due to until about 300 DEG C all It is difficult to occur the reduction of performance, therefore has and need not the fin of heat transmission or can make to dissipate Hot fin the least (height and size diminishes, thinning, miniaturization) advantage.

Second advantage is the thickness that can reduce the device constituting accessory as quasiconductor.Wide taboo The insulation breakdown electric field intensity of band quasiconductor (such as SiC, GaN) is relatively big, therefore quasiconductor Pressure big (have about 10 times of silicon (Si) pressure), therefore can make semiconductor device Thickness little (thin) to about 1/10.In the present embodiment, by use, there is this spy The wide bandgap semiconductor of property, it is possible to achieve the significantly miniaturization of inverting drive circuit accessory, thinning, There is no concern that the structure etc. of heat dissipation environment, therefore, it is possible to obtain design the large and small type of degree of freedom and The second best in quality refrigerator under hot environment.

It is equipped on and controls the semiconductor fittings such as inverting drive circuit accessory of device 30 and use width to prohibit Band quasiconductor, therefore insulation breakdown electric field intensity is big, pressure greatly, such that it is able to reducing thickness and Size (compared with silicon about 1/10).Additionally, also be able to action under the high temperature of 300 DEG C, because of This radiating fin (radiator) that semiconductor fittings can be made to cool down is minimum.Therefore, for In prior art be equipped on control device 30 state have compare other control associations join The inverting i.e. semiconductor fittings of drive circuit accessory of the radiator that part etc. are the most high, in this enforcement By using wide bandgap semiconductor can extremely reduce and make radiator and inverting drive electricity in mode The height of road mate, size (longitudinal and transverse width) (thinning, miniaturization), therefore can Enough when being equipped on control device 30, height reduction is associated accessory to other controls The height of (such as power supply reactor, capacitor, transformator, current detecting accessory etc.) is equal Height below degree or equal extent.

Here, also Vacuumed insulation panel 400 is passed through viscous being configured with the part controlling substrate room 31 Connect agent be adhered directly onto outer container 710 or control substrate room 31, at Vacuumed insulation panel 400 and interior As bonding agent, hard polyurethane foams is set in predetermined thickness (such as 1mm between case 750 Preferably more than 3mm and below 11mm preferably below 6mm above) it is filled with being advisable.

Additionally, in the present embodiment, it is configured to be located at the upper of refrigerator 1 by controlling substrate room 31 Face and with Vacuumed insulation panel 400 by surrounding insulation, and the quasiconductors such as inverting drive circuit accessory are joined When part uses wide bandgap semiconductor, even if controlling surrounding's Vacuumed insulation panel 400 of substrate room 31 Or polyurethane thermal insulation barriers covers and makes to control to be under hot environment in substrate room 31 also not have Problem.During additionally, the semiconductor fittings such as inverting drive circuit accessory use wide bandgap semiconductor, Can also be configured to controlling substrate room 31 in the Machine Room 1A being under hot environment.Wide taboo Even if band quasiconductor can also be not susceptible to compared with existing Si quasiconductor in high temperature environments Fault ground action, therefore the most no problem with thermal insulation barriers Coverage Control substrate room 31.Additionally, will Control when substrate room 31 is configured in the Machine Room 1A being under hot environment without controlling The thermal insulation barriers etc. that is arranged around of substrate room 31 is thermally shielded to prevent from controlling the temperature in substrate room 31 Degree becomes high temperature, therefore can simplify the design controlling substrate room, it is possible to obtain the pressure of low cost Contracting machine, equipment.Additionally, due to without heat insulation to controlling substrate room 31, control therefore can be made The thinning height corresponding with the amount of thickness of thermal insulation barriers of the size of substrate room 31 (or reduce width, Depth) and miniaturization, therefore by the direct bonding Vacuumed insulation panel 400 of bonding agent and control base When plate room 31, Vacuumed insulation panel 400 and interior case 750, it is not necessary to fill the poly-ammonia as thermal insulation barriers Ester, therefore can reduce and arrange the wall (such as upper wall, back face wall etc.) controlling substrate room 31 Wall thickness, can correspondingly increase storeroom internal volume (case internal volume).

Additionally, control substrate room 31, can arrange in the prior art cannot because of the relation in space The surrounding space of the compressor 12 arranged (upper space of the such as terminal box of compressor 12, Lateral space (or surrounding space) etc.), therefore control the degree of freedom of the setting of substrate room 31 (degree of freedom of design) improves, it is possible to acquisition can effectively utilize the space in such as Machine Room 1A Refrigerator, the equipment such as air conditioner.

Here, track component 810 can be located at sidewall 790, it is also possible to be located at configuration orbit portion The partition wall of the storeroom of part 810 (is included between storeroom and storeroom the partition wall arranged And form the bottom surface of storeroom or above partition wall 24 or underside wall 780 or top Wall 740).I.e., it is possible to the track supporting part 820 of supporting track parts 810 is located at (or carry It is placed in) partition wall (including partition wall 24 or roof 740 or underside wall 780).If this The track supporting part 820 of supporting track parts 810 is located at the partition wall 24 of storeroom by sample, just Without arranging fixed component 735 at sidewall 790, the vacuum in sidewall configuration therefore can be increased The thickness of thermal insulation barriers 400, furthermore, it is possible to the Vacuumed insulation panel 400 reduced in sidewall 790 And the thickness of the thermal insulation barriers 701 such as the polyurethane filled between interior case 750.Therefore, it can increase Volume in storeroom or the volume of box body 520.

Here, in the case of track supporting part 820 is located at partition wall, at partition wall 24 Or in underside wall 780 or roof 740, not in the position arranging track fixed component 735 Configuration Vacuumed insulation panel 400 is advisable.If additionally, in the position arranging track fixed component 735 Be provided for the strengthening part of the fixed components such as fixing screw, then fixed component fixing intensity or Person keeps intensity to be improved.Additionally, at Vacuumed insulation panel 400 and the profile of formation partition wall Fill between parts or apply or configure hard polyurethane foams or foam styrene etc. every During warmware, if making the density of thermal insulation barriers more than 60kg/m³, then fixing or holding track component 810 Fixed component or the holding of strengthening part or fixing intensity be improved, therefore reliability Improve.

Above to the feelings that the orbit portion 755 of interior case 750 is fixed with screw etc. inside storeroom Condition (as the head of screw of the screw of fixed component 735 be located at storeroom 2,3,4,5,6 side, Orbit portion 755 and the Vacuumed insulation panel 400 of interior case 750 is located in the threaded portion of fixed component 735 Between situation) be illustrated.But the screw 735 of fixed component can also be made from sidewall 790 Laterally therein storeroom 2,3,4,5,6 in prominent and fix, now, head of screw is located at Between the orbit portion 755 of Vacuumed insulation panel 400 and interior case 750, (orbit portion 755 is fixed in threaded portion Or the thermal insulation barriers 701 such as track strengthening part 731 or polyurethane), even if in this case, Owing to the density of polyurethane is more than 60kg/m³, the therefore intensity increase of polyurethane 701, screw Etc. thermal insulation barriers such as the thermal insulation barriers such as fixed component 735 and polyurethane 701, interior case 750 and polyurethane Fixing intensity or the holding intensity of 701 increase, thus the deformation of interior case etc., strengthening part 731 Dislocation, screw loosen etc. be suppressed, box body 520 grade can be made to pull out swimmingly (can be suitable Freely come in and go out).

In embodiments of the present invention, by the position phase arranging track component with sidewall 790 To position interior case 750 and Vacuumed insulation panel 400 between foaming heat insulation part (such as hard Polyurethane foam) thickness be set as below 11mm (preferably smaller than 10mm), such that it is able to Increase polyurethane Deflection Modulus of Elasticity, therefore can maintain wall intensity while thinning wall Thick.Additionally, by the interior case 750 of position in opposite directions, the position arranging track component with sidewall 790 And the thickness of the foaming heat insulation part (such as hard polyurethane foams) between Vacuumed insulation panel 400 When being set as below 6mm, the Deflection Modulus of Elasticity of polyurethane can be increased further, therefore Can maintain wall intensity while thinning wall thickness.

Additionally, by by the thickness of foaming heat insulation part/(thickness+vacuum heat-insulation of foaming heat insulation part The thickness of part) it is set as less than 0.3, can reduce foaming heat insulation part and Vacuumed insulation panel group The composite guide heating rate of the composite component closed, even if the most thinning wall thickness also can improve thermal insulation Energy.

Additionally, be more than 60kg/m by the density after making polyurethane foam³, it is possible to maintaining wall Intensity while thinning wall thickness.

As above, in embodiments of the present invention, at the track component that arranges with sidewall 790 Foaming heat insulation part (example between interior case 750 and the Vacuumed insulation panel 400 of position in opposite directions, position Such as hard polyurethane foams) thickness be below 11mm (preferably smaller than 10mm), will foaming The thickness of thermal insulation barriers/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) is set as 0.3 Hereinafter, and make the density after polyurethane foam more than 60kg/m³Time, can maintain further Thinning wall thickness while the intensity of wall.Here, the thickness of the foaming heat insulation part in above formula is poly-ammonia The thickness of ester, accordingly, as the thickness of foaming heat insulation part, can be at Vacuumed insulation panel 400 And the thickness P of the thermal insulation barriers 701 such as the polyurethane filled between the orbit portion 755 of interior case 750, Or the thermal insulation barriers 701 such as the polyurethane filled between Vacuumed insulation panel 400 and interior case 750 The thermal insulation barriers such as the polyurethane between thickness Q or Vacuumed insulation panel 400 and strengthening part 731 The thickness R of 701.Such as, the thickness making foaming heat insulation part is Vacuumed insulation panel 400 and strengthens During the thickness R of the thermal insulation barriers 701 such as the polyurethane between parts 731, by the thickness of foaming heat insulation part Degree R/ (thickness of the thickness R+ Vacuumed insulation panel of foaming heat insulation part) is set as less than 0.3. Equally, when to make thickness be P or Q, thickness R is replaced as P or Q.Additionally, The thickness of the polyurethane shown in Figure 17, Figure 18, Figure 19 can also be at Vacuumed insulation panel equally The thickness of the thermal insulation barriers 701 such as the polyurethane filled between 400 and the orbit portion 755 of interior case 750 The thermal insulation barriers 701 such as P, the polyurethane filled between Vacuumed insulation panel 400 and interior case 750 The thermal insulation barriers 701 such as the polyurethane between thickness Q, Vacuumed insulation panel 400 and strengthening part 731 Thickness R.

It is additionally, if making the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is more than 20MPa, permissible Further thinning wall thickness.Here, can not be, track component is fixed to sidewall 790, but It is fixed to the underside wall 780 near sidewall 790 or the partition wall 24 of bottom surface or upper wall (roof) 740 or partition wall above 24.Here, with the fixed components such as screw are set When not configuring Vacuumed insulation panel 400 between interior case 750 and the outer container 710 in opposite directions of position, arrange The underside wall 780 of fixed component or following partition wall 24 or roof 740 or above Partition wall 24 is preferably the wall or partition wall not contacted with exogenous QI.At the wall contacted with exogenous QI (such as sidewall 790, roof 740, back face wall 730, underside wall 780 etc.) reduces not as far as possible The position of Vacuumed insulation panel 400 is set, it is possible to reduces the loss caused because of heat leak, therefore can Enough obtain high performance heat insulating box, refrigerator, equipment.Thereby, it is possible to increase back face wall 730, The configuration area of the Vacuumed insulation panel 400 of sidewall 790, therefore, it is possible to increase heat insulating box 700 In the covering rate of Vacuumed insulation panel 400 or filling rate.

Here, the heat insulating box 700 of present embodiment 1, with the hard in heat insulating box 700 It is different that polyurethane foam mainly undertakes this prior art thought of heat insulating function, and it is based in configuration The part having Vacuumed insulation panel 400 makes Vacuumed insulation panel 400 undertake heat-proof quality and casing intensity This new technological thought.Therefore, the heat insulating box 700 of present embodiment 1 makes at outer container The filling of the Vacuumed insulation panel 400 in space 315 in the wall formed between 710 and interior case 750 (volume of Vacuumed insulation panel 400 is relative to formation between outer container 710 and interior case 750 for rate Ratio shared by the cumulative volume in space 315 in wall) it is more than predetermined value (for example, more than 40% (preferably more than 45%)).Here, the filling rate of Vacuumed insulation panel 400 also include vacuum every The volume of warmware 400 is empty relative in the door between external door panel and the door inner panel of the profile forming door Between the ratio shared by the volume i.e. filling rate of door.

In prior art, so that Vacuumed insulation panel is relative to outer container 710 or the table of interior case 750 Area ratio (covering rate) shared by area mode within a predetermined range configure vacuum every Warmware, and do not consider the impact of the thickness of Vacuumed insulation panel 400, therefore make rigid polyurethane foam The thickness of foam is bigger than the thickness of Vacuumed insulation panel 400, heat insulation to be had by hard polyaminoester The intensity of casing.In prior art, the covering rate of Vacuumed insulation panel 400 to be increased improves casing Heat-proof quality, but not increase Vacuumed insulation panel 400 filling rate improve heat-proof quality and Casing intensity both sides, therefore less (the most existing refrigerator of the filling rate of Vacuumed insulation panel 400 In filling rate be about 20%), there is the situation that heat-proof quality does not improves, and casing intensity depend on Rely in hard polyurethane foams.In the present embodiment, to consider Vacuumed insulation panel 400 The mode of the filling rate of thickness configures Vacuumed insulation panel 400, thus without as prior art that Sample does not improves heat-proof quality.By making the filling rate of Vacuumed insulation panel 400 be more than predetermined value (example Such as more than 40%), heat-proof quality is improved, and can meet casing intensity, heat insulation Thinning wall thickness while performance, therefore, it is possible to increase storeroom internal volume, it is possible to wanted by product The storeroom internal volume asked is set as more than predetermined capacity.I.e., it is possible to suitably set vacuum The length of thermal insulation barriers 400, width, thickness, configuration position, it is possible to reduce wall thickness, it is possible to phase Storeroom internal volume should be increased in ground.

By increasing the filling of the Vacuumed insulation panel 400 in space 315 the most compared to existing technology Rate so that heat-proof quality increases compared to existing technology, even if subtracting the most compared to existing technology The wall thickness of thin heat insulating box 700, it is also possible to guarantee the equal extent that heat-proof quality is prior art Above.

(other of the 1st wind path accessory are constituted)

As mentioned above, in embodiments of the present invention, such as Fig. 4, Fig. 5, Fig. 6, The width of the 1st wind path accessory 762 of the part forming cold air wind path 760 shown in Fig. 8 etc. Direction length is less than the width of recess 440, in protuberance 450 or second recesses 441 or formed Jut 910 grade of second recesses 441 by the fixed components such as screw or hooking structure or Embedded structures etc. are fixed or keep.Here, of formation cold air wind path 760 can be made The width length of the 1st wind path accessory 762 divided is to cover back face wall 730 or sidewall 790 The mode of a part reach the inner face of sidewall 790 and the 1st wind path accessory 762 passed through spiral shell The fixed components such as nail or hooking structure or embedded structure etc. are fixed or remain to sidewall 790 Inner face.Certainly, the 1st wind path accessory 762 is possible not only to fixing or remains to the interior of sidewall 790 Face, it is also possible to fix by fixed component or hooking structure or embedded structure etc. or remain to Jut 910, recess 440, protuberance 450 etc..

If additionally, making the width of the 1st wind path accessory 762 of a part for formation cold air wind path 760 Degree direction length reaches the inner face of sidewall 790 thus not only covers second recesses 441 and also cover Recess 440, protuberance 450 at least some of or all, then the 1st wind path accessory 762 can To be also used as the Appearance Panel, back face wall or the sidewall of room (such as storeroom) can be covered Inner face at least some of or all, can be using the 1st wind path accessory 762 as covering the back of the body The cap assembly of a part for face or side uses.Therefore, will be to indoor supply from cold air When the supply mouth of the cold air of wind path 760 is located at the 1st wind path accessory 762, configuration can be improved Degree of freedom, efficiently the storage thing in cooling chamber, additionally, the 1st wind path accessory 762 can make With another parts different from interior case 750, therefore can easily change shape or color or Carrying out all processing, coating or literature record etc., functional, aesthetic appearance is improved.By When 1 wind path accessory is also used as the Appearance Panel and uses as cap assembly, it is shaped generally as U-shaped Shape and cover at least some of of the back face wall 730 of forming chamber and the inner face of sidewall 790 or Whole inner faces of wall are advisable.Now, illuminator (case intraoral illumination) is if 900 are configured at shape Become roof 740 or the underside wall 780 of room, then make the 1st wind path accessory as cap assembly 762 when reaching sidewall 790, with the situation that illuminator 900 is located at sidewall 790 inner face Compare, it is not necessary to the 1st wind path accessory 762 being provided with the part of illuminator 900 is excised or sets Putting opening, therefore the shape as the Appearance Panel (the 1st wind path accessory 762) of cap assembly becomes Obtain easily, it is possible to obtain the heat insulating box of low cost, refrigerator, equipment.Here, as cover portion The Appearance Panel of part can be formed as covering the roof 740 of forming chamber and back face wall 730 at least A part or whole inner face side of wall.

(thickness of polyurethane, the filling rate of Vacuumed insulation panel)

Here, the relation of the filling rate of Vacuumed insulation panel 400 and the intensity of casing is illustrated. Figure 15 is the figure of the relation representing the density of hard polyurethane foams and thermal conductivity, and Figure 16 is table Showing the density of hard polyurethane foams and the figure of Deflection Modulus of Elasticity, Figure 17 is to represent to be filled with firmly The figure of the relation of the stream thickness of polyurethane during matter polyurethane and the thermal conductivity of polyurethane, Figure 18 It is the bending resistance elasticity of stream thickness and the polyurethane representing polyurethane when being filled with hard polyaminoester The figure of the relation of modulus.Figure 15～Figure 18 is in two faces with predetermined gap (stream) Between fill hard polyaminoester make the experimental result under its model configuration body foamed, stream The face of side is that the steel plate as the 1st parts (such as forms Vacuumed insulation panel or refrigerator 1 The profile of the heat insulating box 700 i.e. coated steel plate of outer container 710), the face of the opposite side of stream is to make Be the 2nd parts resin (ABS that such as, interior case 750 is used (acrylonitrile, butadiene, Cinnamic copolymerization resin), the resin such as EPS (foamed plastic)).

In Figure 15, transverse axis represents the density (kg/m of hard polyurethane foams³), the longitudinal axis represents hard The thermal conductivity [W/ (m K)] of matter polyurethane foam.Additionally, in Figure 16, transverse axis represents hard Density (the kg/m of polyurethane foam³), the longitudinal axis represents the bending resistance springform of hard polyurethane foams Amount (MPa).In Figure 17, transverse axis represents the stream thickness (mm) filling hard polyurethane foams, The longitudinal axis represents the thermal conductivity [W/ (m K)] of hard polyurethane foams.In Figure 18, transverse axis represents Filling the stream thickness (mm) of hard polyurethane foams, the longitudinal axis represents hard polyurethane foams Deflection Modulus of Elasticity (MPa).Here, the stream thickness filling hard polyurethane foams represents Fill hard polyurethane foams the thickness of the hard polyurethane foams of state foamed in stream Degree.

According to Figure 15, Figure 16, hard polyurethane foams is thermal conductivity, bending resistance bullet when density is the biggest Property modulus is the biggest, the least at density more hour thermal conductivity, Deflection Modulus of Elasticity.That is, density and Thermal conductivity or density and Deflection Modulus of Elasticity are essentially proportional relation.

According to Figure 17, Figure 18, hard polyurethane foams filled polyurethane stream thickness (or Person fills hard polyurethane foams the thickness of the polyurethane of state foamed in stream) more Time narrow, thermal conductivity is the biggest, additionally, Deflection Modulus of Elasticity is the biggest.Therefore, foam in stream After the thickness of polyurethane the thickest, thermal conductivity is the least, and heat-proof quality is the highest, but bending resistance springform Measuring the least, intensity is the lowest.Therefore, when the thickness of polyurethane to be reduced is with thinning wall thickness, bending resistance Elastic modelling quantity increases, therefore no problem in intensity, but thermal conductivity becomes excessive, thermal insulation Can deteriorate, the thickness of polyurethane therefore cannot be made less than to a certain degree (such as 15mm).

Here, at Figure 17, Tu18Zhong, if the stream thickness of filled polyurethane (or stream The thickness of the polyurethane after interior foaming) narrow, then density increases, if density increases, then such as figure Thermal conductivity shown in 15 increases, and heat-proof quality deteriorates.Here, as shown in figure 17, if filling poly- The stream thickness (or thickness of the polyurethane after foaming in stream) of urethane becomes predetermined thickness (such as 11mm) below, then thermal conductivity is increased dramatically, and heat-proof quality deteriorates.Hard polyaminoester Foam foaming bonding to the between the 1st parts and the 2nd parts forming polyurethane stream Solidifying under the state of 1 parts and the 2nd parts, now, polyurethane forms sandwich layer and at this sandwich layer Both sides (the 1st component side and the 2nd component side) formed be referred to as cortex boundary region.

Figure 23 A and Figure 23 B is the schematic diagram of the cross sectional shape after hard polyurethane foams foaming, Figure 23 A is to represent between the 1st parts (interior case 750) and the 2nd parts (outer container 710) The schematic diagram in cross section when being filled with hard polyurethane foams 701A, Figure 23 B is to represent The 3rd parts it are folded with (true between 1 parts (interior case 750) and the 2nd parts (outer container 710) Empty thermal insulation barriers 400) time between the 1st parts and the 3rd parts, be filled with hard polyurethane foams The schematic diagram in cross section during 701A.

In Figure 23 A, possesses polyurethane foam filled between the 1st parts and the 2nd parts Thermal wall successively by the 1st parts (such as in case 750), the 1st cortex 701B, sandwich layer 701C, 2nd cortex 701D, the 2nd parts (such as outer container 710) are constituted.On the other hand, such as Figure 23 B Shown in, as the 3rd between the 1st parts (interior case 750) and the 2nd parts (outer container 710) During parts configuration Vacuumed insulation panel 400, thermal wall successively by the 1st parts (interior case 750), the 1 cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 3rd parts (Vacuumed insulation panel 400), 2nd bonding agent the 715, the 2nd parts (outer container 710) is constituted.It addition, the 1st cortex 701B, Sandwich layer 701C and the 2nd cortex 701D constitutes hard polyurethane foams 701A.

Cortex is formed at the 1st nearby components or the 2nd nearby components or the 3rd nearby components, The stream thickness (thickness of polyurethane) of polyurethane be prior art use scope the most about During 20mm～30mm, the thickness of cortex is sufficiently small relative to the thickness of sandwich layer, to density, leads The impact of heating rate etc. is the least, if but the thickness of polyurethane be predetermined thickness (such as 11mm) with Under, then the thickness of cortex becomes big relative to the ratio shared by the thickness of sandwich layer, close to polyurethane Degree, thermal conductivity, the impact of Deflection Modulus of Elasticity are increased dramatically, density, thermal conductivity, bending resistance bullet Property modulus drastically becomes big.Therefore, heat-proof quality drastically deteriorates.Additionally, as shown in figure 18, by Density in polyurethane rises, and the Deflection Modulus of Elasticity of polyurethane also steeply rises.

Therefore, in prior art, if reducing the thickness of polyurethane, then Deflection Modulus of Elasticity increase, Intensity improves, but the thermal conductivity of polyurethane rises, heat-proof quality deteriorates, and therefore cannot reduce poly- The thickness of urethane, and in the scope use of about 15mm～30mm.In prior art, with poly- Urethane be main thermal insulation barriers, Vacuumed insulation panel be that the mode of auxiliary thermal insulation barriers configures, therefore exist The heat-proof quality of polyurethane thermal insulation barriers determines the thickness of polyurethane in the range of will not deteriorating, even if About 15mm～20mm is also ensure that in narrow part.

But, in the present embodiment, it is main thermal insulation barriers with Vacuumed insulation panel and passes through vacuum The mode of the intensity that thermal insulation barriers obtains casing forms thermal wall, is therefore configured with Vacuumed insulation panel The hard polyaminoester of part do not require heat-proof quality, even if thus be predetermined thickness (such as 11mm, preferably 6mm) the most no problem, the thinnest then Deflection Modulus of Elasticity rises, case Body intensity improves, the best.When predetermined thickness is below 11mm, the thickness pair of cortex The impact of sandwich layer becomes big, and thermal conductivity is increased dramatically, and heat-proof quality drastically reduces, the most existing skill The thickness being difficult to make hard polyurethane foams in art is below 11mm.In prior art, about The thickness of hard polyurethane foams, though local little scope can make predetermined value be 11mm with Under, it is also difficult to making average thickness is below 11mm.And then, if predetermined thickness is 6mm Hereinafter, then the impact of sandwich layer is increased by the thickness of cortex further, and heat-proof quality more deteriorates, Therefore prior art is difficult with.But in the present embodiment, make Vacuumed insulation panel 400 have There is the heat-proof quality of heat insulating box 700, even if the thickness of the most thinning polyurethane uses and also do not has Problematic.Therefore, in the present embodiment, by the thickness of hard polyurethane foams is set For below 11mm (preferably smaller than 10mm), the bending resistance bullet of hard polyurethane foams can be increased Property modulus, improve casing 700 intensity (rigidity).If additionally, by hard polyurethane foams Thickness is set as below 6mm, and the bending resistance that can increase hard polyurethane foams further is elastic Modulus, therefore the intensity (rigidity) of casing 700 is further enhanced.

It addition, do not configuring the part of Vacuumed insulation panel 400, the thickness of polyurethane can be with very The thickness (e.g., from about 15mm～30mm) of empty thermal insulation barriers formed thicklyer, therefore polyurethane Thickness may insure that about 20mm～40mm, can not steeply rise in the thermal conductivity of polyurethane Scope (below the thickness 11mm of polyurethane) uses, can upper in the thermal conductivity of polyurethane (thickness of such as polyurethane is the model of such as more than 15mm to the degree of liter (slope) little scope Enclose) use, even if therefore considering that the uneven thickness of polyurethane can also ensure that the heat insulation of polyurethane Performance is below predetermined value.Therefore, it can meet intensity and the heat insulating box of heat insulating box 700 The heat-proof quality both sides of 700.

Here, the 1st parts used in the face of the side of polyurethane stream, use resin (example As, ABS (acrylonitrile, butadiene, the cinnamic copolymerization tree that interior case 750 is used Fat) or EPS (resin such as foamed plastic)).The face of the opposite side of stream uses as vacuum The aluminium-vapour deposition film of the outsourcing material of thermal insulation barriers, the coated steel plate (PCM) etc. of formation outer container 710 Steel plate.

Next explanation be configured with the part of Vacuumed insulation panel 400 (such as recess 440 or Second recesses 441 etc.), the thickness of polyurethane is relative to possessing polyurathamc and Vacuumed insulation panel The ratio of the thickness (thickness of the thickness+polyurethane of Vacuumed insulation panel) of the thermal wall of 400 (= The thickness of polyurethane/(thickness of polyurethane+Vacuumed insulation panel thickness)) and composite guide heating rate (by The thermal conductivity of the thermal wall of Vacuumed insulation panel and polyurethane composition) relation.

Figure 19 is to represent polyurethane when wall thickness (thickness between the inwall of wall) is fixed as 27mm Thickness relative to by the ratio of the thickness of the thermal insulation barriers of Vacuumed insulation panel and polyurethane composition The figure of the relation of rate and composite guide heating rate.In Figure 19, transverse axis represents the thickness phase of polyurethane For by the ratio of the thickness of the thermal insulation barriers of Vacuumed insulation panel and polyurethane composition, the most poly-ammonia The thickness of ester/(thickness of polyurethane+Vacuumed insulation panel thickness), the longitudinal axis represents that composite guide heating rate (will The thermal conductivity that Vacuumed insulation panel and polyurethane composition get up).Here, by the thickness of polyurethane with true The thickness of the thickness+Vacuumed insulation panel of the empty total of thickness of thermal insulation barriers, i.e. polyurethane is as wall Interior thickness.

It appears from figure 19 that relative to thickness in wall, when the thickness of polyurethane is less, composite heat-conducting Rate diminishes, and heat-proof quality improves.Here, composite guide heating rate represents polyurethane and vacuum heat-insulation The thermal conductivity of the composite component that part combines.In figure, in the thickness/wall of polyurethane, thickness is with 0.3 Change for boundary's slope, with thickness in the thickness/wall of polyurethane more than 0.3 time compared with, poly-ammonia In the thickness/wall of ester, thickness is when about less than 0.3, and slope is less, the reduction of composite guide heating rate Ratio is less.Figure is thickness one experimental verification regularly in wall, therefore in the thickness/wall of polyurethane The ratio of thickness is the least, and the thickness of polyurethane is the least, otherwise the thickness of Vacuumed insulation panel is the biggest, because of The thickness of this Vacuumed insulation panel is the biggest relative to the ratio shared by thickness in wall.That is, relative to wall Interior thickness, when the thickness of polyurethane diminishes, the thickness of Vacuumed insulation panel is relative to the thickness of polyurethane The ratio of degree increases.In figure, in the thickness/wall of polyurethane, thickness is about at 0.6, polyurethane Thickness bigger than the thickness of Vacuumed insulation panel, therefore the thermal conductivity of polyurethane is (true to composite guide heating rate Empty thermal insulation barriers and polyurethane thermal conductivity altogether) impact relatively big, composite guide heating rate is the biggest (heat-proof quality is poor).If reducing thickness in the thickness/wall of polyurethane, the then thickness of Vacuumed insulation panel Relative to polyurethane thickness ratio increase, therefore compare the thermal conductivity of polyurethane, vacuum every The thermal conductivity of warmware on the impact of composite guide heating rate relatively big as a result, along with polyurethane thickness/ (thickness of the thickness+Vacuumed insulation panel of polyurethane) diminishes, polyurethane and Vacuumed insulation panel combination Composite component thermal conductivity (composite guide heating rate) reduce.Here, until polyurethane When thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) is about 0.3, compare polyurethane Thermal conductivity, the thermal conductivity of Vacuumed insulation panel is relatively big on the impact of composite guide heating rate, is therefore combined The reduction ratio of thermal conductivity is the biggest, the thickness of polyurethane/(thickness+vacuum heat-insulation of polyurethane The thickness of part) the least, composite guide heating rate is the least, and heat-proof quality is greatly improved.

But, from the thickness of polyurethane relative to the thickness of the ratio of thickness, i.e. polyurethane in wall/ Rise during (thickness of the thickness+Vacuumed insulation panel of polyurethane) less than about 0.3, composite guide heating rate The slope reduced changes, and the slope of the reduction of composite guide heating rate diminishes (composite guide heating rate The ratio reduced diminishes).This be considered as due to, the thickness of polyurethane is relative to thickness in wall In the thickness/wall of ratio, i.e. polyurethane, thickness diminishes, thus relative to composite component (by poly-ammonia The parts that ester and Vacuumed insulation panel combine) heat-proof quality, the thermal insulation of Vacuumed insulation panel Can become overriding, the impact of the heat-proof quality of composite component is become by the heat-proof quality of polyurethane Little.Therefore, in the present embodiment, by composite component (polyurethane and Vacuumed insulation panel pair The heat insulating member that Fang Xianglin is formed) thermal wall that formed, so that thickness in the thickness/wall of polyurethane Being mode when setting the thickness of polyurethane of less than 0.3, the ratio of the reduction of heat-proof quality diminishes, Even if therefore the thickness of polyurethane or the thickness of Vacuumed insulation panel produce inequality, it is possible to make heat insulation The inequality of performance is less, the most preferably.Otherwise, it is also possible to by the thickness/wall of Vacuumed insulation panel Thickness is set as more than 0.7.

Therefore, in the way of thickness is about below 0.3 in the thickness/wall making polyurethane, poly-ammonia is set During the thickness of ester, can reduce composite guide heating rate, the heat-proof quality of composite component is significantly carried High.If additionally, consider the inequality of the thickness of polyurethane, (or the thickness of Vacuumed insulation panel is not All) it is set so that thickness is in the scope of less than 0.3, then in the thickness/wall of polyurethane Even if the thickness of the thickness of polyurethane, Vacuumed insulation panel produces inequality, it is also possible to suppression composite part The reduction of the heat-proof quality of part, and the inequality of the composite guide heating rate of composite component can be suppressed, Therefore, it is possible to obtain reliability thermal wall high, high performance, heat insulating box, refrigerator, equipment etc..

Figure 20 is that the volume representing Vacuumed insulation panel 400 is relative to the volume institute in space 315 in wall The ratio accounted for the i.e. filling rate of Vacuumed insulation panel and to heat insulating box 700 imposed load (load) Time the figure of relation of deflection of heat insulating box.In fig. 20, transverse axis represents Vacuumed insulation panel Filling rate, the longitudinal axis represent the deflection of heat insulating box.Here, the filling rate of Vacuumed insulation panel It it is the Vacuumed insulation panel 400 ratio (ratio relative to the volume shared by the volume in the space 315 in wall Example), the deflection of heat insulating box is to have the state of door in the heat insulating box of such as refrigerator 1 grade Under on the side of distance casing the height and position of about about 1/4 (horizontal in a generally horizontal direction To, observe front openings portion in front time be left and right directions) be applied with predetermined load time case The upper end position of the sidewall 790 of body 700 is tied in the calculating of the deflection of left and right directions (laterally) Really, if the filling rate of Vacuumed insulation panel 400 is deflection when 20% is 1.Figure 20 is to make very The empty covering rate (such as 65%) of thermal insulation barriers, polyurethane density (such as 60kg/m³), poly-ammonia The Deflection Modulus of Elasticity (such as 9MPa) of ester, Vacuumed insulation panel Deflection Modulus of Elasticity (such as 15MPa), the thickness of thickness (such as 28mm), outer container and the interior case of composite component is added Wall thickness (such as 30mm) etc. are fixing and make the thickness of Vacuumed insulation panel change to change vacuum The result during filling rate of thermal insulation barriers.

In fig. 20, the filling rate of Vacuumed insulation panel is the biggest, and box deformation amount is the least.This is recognized For being owing to, the Deflection Modulus of Elasticity of Vacuumed insulation panel is bigger than the Deflection Modulus of Elasticity of polyurethane, Thus increase relative to the ratio of the polyurethane volume in heat insulating box with the volume of Vacuumed insulation panel Adding, the impact of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes big, and the rigidity of casing 700 increases. When the filling rate of Vacuumed insulation panel 400 is more than 40%, the reduction ratio of the deflection of casing becomes Obtaining minimum, even if the filling rate of Vacuumed insulation panel increases, box deformation amount becomes the most hardly Change.This be considered as due to, Vacuumed insulation panel 400 is for casing intensity (deformation of casing) Influence degree substantially close to saturated.

The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is bigger than hard polyurethane foams, therefore passes through Increase the volume of Vacuumed insulation panel 400 relative to the ratio (ratio shared by the volume in space 315 Example) (increasing the filling rate of Vacuumed insulation panel), it is possible to reduce the deflection of heat insulating box 700, Therefore, it is possible to improve the heat-proof quality of heat insulating box 700, increase heat insulating box 700 or refrigerator 1 or the casing intensity of equipment.Now, if the thickness increasing Vacuumed insulation panel 400 increases Filling rate, it becomes possible to improve heat-proof quality while the effect that the intensity realizing casing improves. Here, the filling rate of Vacuumed insulation panel can be increased by increasing the thickness of Vacuumed insulation panel, Can also be by increasing the surface area surface area relative to casing 700 of Vacuumed insulation panel 400 Ratio (covering rate of Vacuumed insulation panel) increases the filling rate of Vacuumed insulation panel, the most also may be used To increase the intensity of casing, and, by increasing the covering rate of Vacuumed insulation panel 400, permissible Increase the filling rate of Vacuumed insulation panel.If additionally, increase the covering rate of Vacuumed insulation panel 400, Then the configuration scope (configuration position) of Vacuumed insulation panel increases, can be with thinning heat insulating box 700 Wall thickness, therefore can make storeroom internal volume increase wall thickness reduction amount.

In the present embodiment, such as, the outer container 710 of profile and the shape of heat insulating box are being formed Space 315 between the interior case 750 of a part for the inwall of the storeroom of one-tenth heat insulating box is extremely A few part possesses Vacuumed insulation panel 400, makes filling out of the Vacuumed insulation panel 400 in space 315 The rate of filling is more than 40%, and makes the Vacuumed insulation panel 400 face relative to the surface area of outer container 710 Long-pending ratio (covering rate) is more than 60% such that it is able to obtain heat-proof quality height, casing intensity Also big and heat insulating box that reliability is high, refrigerator, equipment etc..Here, in the present embodiment, It is configured to higher than the hard polyurethane foams used by existing heat insulating box by Deflection Modulus of Elasticity Vacuumed insulation panel 400 undertakes the wall intensity of heat insulating box 700, therefore, it is possible to meet simultaneously Casing intensity and heat-proof quality, and can thinning wall thickness, therefore storeroom internal volume also can increase Greatly.

The heat insulating box 700 of present embodiment is by by higher than hard polyaminoester for bending strength true The filling rate of empty thermal insulation barriers 400 is set as more than predetermined value (or in preset range) or incites somebody to action The filling rate of Vacuumed insulation panel 400 and covering rate both sides are set as that more than predetermined value is (or predetermined In the range of), it is possible to meet heat-proof quality and casing intensity and can thinning heat insulating box simultaneously The wall thickness of 700.Therefore, need not change heat insulating box 700, the overall dimensions of refrigerator 1 can expand Internal volume in big storeroom, can increase at heat insulating box 700 or refrigerator 1 or equipment Inside can store storage thing, reserve.During it addition, wall intensity reduces, it may occur that Heat insulating box 700 deforms, such as, is located at the shelf 80 offset track portion of inside and falls or take out The sliding of the storeroom of drawer formula (or the door of drawer type or box body or shutter door etc.) becomes The problems such as difference.But in the present embodiment, due to by the filling rate of Vacuumed insulation panel 400 or/ And covering rate is set as more than predetermined value (in preset range), therefore can be with thinning heat insulating box The wall thickness of 700, and casing intensity and heat-proof quality can be improved, therefore, it is possible to below Yi Zhi The generation of situation: shelf 80 offset track portion and fall, or storeroom (or the door of drawer type Or box body or shutter door etc.) sliding be deteriorated, cause reliability to reduce.

Additionally, the heat insulating box 700 of present embodiment 1 makes the Vacuumed insulation panel in space 315 The filling rate of 400 is less than 90%.According to the technological thought of above-mentioned present embodiment, preferable Be all Vacuumed insulation panels 400 in space 315.But, as illustrated by Figure 11 etc. Like that, in wall 730 is provided with protuberance 450 or jut 910, makes in addition to be formed at overleaf The orbit portion 755 of case 750 is protrusively provided, in addition by heat insulating box 700 in space 315 When such as refrigerator 1, in wall, in space 315, to be also configured to receive the pipe of wire harness 720, therefore, it is difficult to make the filling rate of Vacuumed insulation panel 400 more than 90%, above-mentioned wire harness is logical Cross and will connect compressor 12, the control substrate room carried in the Machine Room 1A of heat insulating box 700 The distribution of the control device 30 (such as controlling the device of the rotating speed etc. of compressor) etc. of storage in 31 Class boundling.During additionally, heat insulating box 700 is applied to such as refrigerator 1, in space Refrigerant piping 725 to be configured etc. in 315.Therefore, in space 315 more than 90% Ground configuration Vacuumed insulation panel 400, it is necessary to distribution class 720, refrigerant piping 725, track The Vacuumed insulation panel 400 of the form fit of portion 755 grade, the shape of Vacuumed insulation panel 400 becomes Complexity, thus the molding of Vacuumed insulation panel 400 (or formation) becomes difficulty, therefore will be true The filling rate of empty thermal insulation barriers 400 is set as less than 90%.

Additionally, the problem deformed to suppress the intensity of heat insulating box 700 to reduce, need Outer container 710 to be made and interior case 750 are bonding with Vacuumed insulation panel 400 and possess adhesive strength, and It is provided with at interior case 750 and is located at the shelf 80 in storeroom (such as cold room 2) for holding Orbit portion 755, other accessories (such as illuminator 900 or mist device 200 or point Next door 24 etc.) situation more, complex-shaped.Therefore, even if being prone to Vacuumed insulation panel 400 by PUR or double faced adhesive tape etc. the 2nd bonding agent bond to outer container 710 side, it is also difficult to make Vacuumed insulation panel 400 bonds to complex-shaped interior case 750 side and obtains adhesive strength.

But, using hard polyurethane foams as between interior case 750 and Vacuumed insulation panel 400 When bonding agent uses, it can be made to fill while flowing with two-phase state in space 315, Foaming, though therefore exist in space 315 protuberance 450, jut 910, orbit portion 755, Polyurethane can also be passed through without problems by interior case 750 and Vacuumed insulation panel 400 during other accessories It is bonded together.It is of course also possible between outer container 710 and Vacuumed insulation panel 400 or outer Hard polyurethane foams is filled as bonding agent between case 710 and interior case 750.Now, if The portion that is not filled by (i.e. space) being not filled by hard polyurethane foams is produced, then in heat insulating box 700 The heat-proof quality of heat insulating box 700 can reduce.Therefore, at the heat insulating box 700 of present embodiment In, therefore, to assure that for filling a certain degree of predetermined gap (example needed for hard polyurethane foams Such as from about more than 1mm, preferably from about more than 3mm), the therefore Vacuumed insulation panel in space 315 The filling rate of 400 can be less than 90%, preferably less than 80%.

But, if making the filling rate of the Vacuumed insulation panel 400 in space 315 increase, then space The filling rate of the hard polyurethane foams in 315 will reduce.Therefore, outer container 710 and interior case The thickness of the polyurethane between 750 reduces, and may result in the casing intensity of heat insulating box 700 Reduce.But, the heat insulating box 700 of present embodiment is by using heat-proof quality, bending resistance firm The Vacuumed insulation panel 400 that property is all good than polyurethane, can suppress the reduction of casing intensity.Additionally, In the present embodiment, technological thought is mainly to be undertaken by the Vacuumed insulation panel 400 that thermal conductivity is little Heat insulating function and intensity, the most as shown in figure 20, by making the filling rate of Vacuumed insulation panel be More than 40%, even if the loading of hard polyaminoester reduces, it is also possible to improve the strong of casing 700 Degree.Additionally, as shown in figure 19, (i.e. increase true by thickening the thickness of Vacuumed insulation panel 400 The filling rate of empty thermal insulation barriers), can reduce Vacuumed insulation panel and hard polyurethane foams combination The composite guide heating rate of the compound heat-insulation part become, therefore the heat-proof quality of casing 700 also improves.

If here, the density increasing hard polyurethane foams increases Deflection Modulus of Elasticity (bending resistance Rigidity), then the heat-proof quality of hard polyurethane foams self can reduce, but by making vacuum heat-insulation The covering rate of part 400 and filling rate are more than predetermined value, the reduction of the heat-proof quality of polyurethane Impact can diminish and not become problem.In the heat insulating box 700 of present embodiment, such as Figure 16 Shown in, bigger than prior art by the density making hard polyurethane foams, be greater than 60kg/m³, the Deflection Modulus of Elasticity of hard polyurethane foams can be made for than existing heat insulating box The Deflection Modulus of Elasticity (e.g., from about 6～10MPa) of the hard polyurethane foams used is big More than 15MPa, it is also possible to improve the casing intensity of the part not configuring Vacuumed insulation panel 400. Therefore, the equipment such as the heat insulating box 700 of present embodiment, refrigerator 1, showcase, hot water supply device, By to make the filling rate of Vacuumed insulation panel 400 be more than 40%, make the back side, side of Vacuumed insulation panel Covering rate be more than 70%, it is possible to suppress to lead because of the reduction of the filling rate of hard polyurethane foams The intensity caused reduces, additionally it is possible to suppression heat insulating box 700 is led because of the weight that cannot tolerate storage thing Cause crooked and deform.That is, by increasing the filling rate of Vacuumed insulation panel 400, can improve The intensity of heat insulating box 700, furthermore, it is possible to obtain excellent heat-proof quality, therefore, it is possible to obtain Obtain the high and energy-conservation heat insulating box possessing Vacuumed insulation panel of reliability, possess Vacuumed insulation panel Refrigerator, possess the showcase of Vacuumed insulation panel, possess the hot-water supply of Vacuumed insulation panel, tool The equipment etc. of standby Vacuumed insulation panel.

It addition, the density of hard polyurethane foams adjusts, such as can be by making to be injected into space The amount of the stock solution of the hard polyurethane foams in 315 is filled more than prior art and (is lengthened note The angle of incidence or increasing injection pressure) and density is adjusted so as to larger or smaller.Additionally, it is hard The Deflection Modulus of Elasticity of matter polyurethane foam is the most proportional to the size of density as shown in figure 16 Ground increases, and therefore increases density and just can increase Deflection Modulus of Elasticity, and Deflection Modulus of Elasticity is relatively Time big, gear housing rigidity increases, and the most preferably, but the Deflection Modulus of Elasticity of polyurethane is preferably Below 150MPa.If the Deflection Modulus of Elasticity of hard polyurethane foams is more than 150MPa, the most firmly The density of matter polyurethane foam becomes excessive, can cannot be foamed into spongy and solidify, thermal insulation Can drastically reduce, when therefore the Deflection Modulus of Elasticity of hard polyurethane foams is below 150MPa The reduction of heat-proof quality can be suppressed thus preferred, it is possible to obtain high performance heat insulating box.

In the present embodiment, heat insulating box 700 is such as applied to the refrigerator of following specification.

(1) use outer container 710 and total thickness of slab about below the 2mm of interior case 750, include The average wall thickness of the thickness of slab of outer container 710 and the heat insulating box 700 of interior case 750 thickness of slab is about 20mm Below the heat insulating box of about below 40mm is (here, eliminate outer container 710 and interior case 750 The average distance (thickness in wall) in the wall thickness direction in the space 315 of thickness of slab is about 18mm～about 38mm)。

(2) thickness of Vacuumed insulation panel 400 is about 10mm～about 30mm, is configured with vacuum Space 315 in the wall of the part (such as recess 440 or second recesses 441) of thermal insulation barriers In the mean flowpath width (polyurethane stream thickness) in wall thickness direction of hard polyurethane foams For more than 1mm (preferably more than 3mm), below 11mm (preferably below 6mm).

(3) thermal conductivity of hard polyurethane foams is 0.018W/ (m K)～0.026W/ (m K).

(4) thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (m K)～0.0025W/ (m·K)。

(5) the consumption electric power under internal volume is 200L～600L level, predetermined condition is about 60W Following degree.

The heat-proof quality of this refrigerator 1 by be set to make Vacuumed insulation panel 400 filling rate and Covering rate within a predetermined range and selects the size of Vacuumed insulation panel 400, thickness, makes true Empty thermal insulation barriers 400 becomes relative to the heat-proof quality of heat insulating box, the casing intensity of heat insulating box Overriding, thus when the thermal conductivity of Vacuumed insulation panel 400 is less, heat insulating box can be reduced Composite guide heating rate thus preferably, preferably 0.0030W/ (m K) is below.If vacuum heat-insulation The thermal conductivity of part 400 is more than 0.0030W/m K, then wall thickness reduces the change of the impact on heat-proof quality Greatly, heat-proof quality deteriorates, and consumes amount of power and increases.Therefore, in the present embodiment, pass through Make the thermal conductivity of Vacuumed insulation panel 400 be 0.0030W/ (m K) below, it is possible to suppress and subtract The impact that the thick relative heat-proof quality of thin-walled reduces.Additionally, the thermal conductivity of Vacuumed insulation panel 400 The smaller the better, but in order to thermal conductivity being reduced the cost spent by 0.001W/ (m K) significantly Increasing, the thermal conductivity therefore using Vacuumed insulation panel 400 is more than 0.0012W/ (m K) Parts.If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (m K) above 0.0025W/ (m K) is below, just little than the thermal conductivity of hard polyurethane foams about 10 times, the most heat insulation The heat-proof quality of casing 700 is the best, it is possible to meet product specification.Therefore, Vacuumed insulation panel 400 uses thermal conductivity to be about 0.0012W/ (m K) above 0.0030W/ (m K) The portion of (preferably from about 0.0019W/ (m K) above 0.0025W/ (m K) is below) below Part.

As an example of the heat insulating box 700 of embodiments of the present invention, wall is shown in Table 1 Thick and the filling rate of Vacuumed insulation panel 400, the Deflection Modulus of Elasticity of hard polyurethane foams, every The relation of the box deformation amount of hot tank body 700.The item 1 of table 1 is existing specification, is wall thickness For the filling rate of 40mm, Vacuumed insulation panel 400 be 20%, at interior case 750 and vacuum heat-insulation The Deflection Modulus of Elasticity of the polyurethane filled between part 400 is result during 9MPa.Here, The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 uses the parts of 20MPa.Item 1 according to table 1 With item 2, the filling rate of Vacuumed insulation panel 400 is 20%, the Deflection Modulus of Elasticity of polyurethane is During 9MPa, if making the wall thickness of heat insulating box 700 be thinned to 30mm from 40mm, then casing Intensity reduces.Therefore, understand as shown in item 3, make wall thickness reduction in the case of 30mm, If the filling rate making Vacuumed insulation panel 400 increases to more than 40%, although then box deformation amount ratio Item 1 (prior art) is slightly larger, but is reduced to the degree equal with item 1 (prior art).

As shown in the item 4 of table 1, even if by the wall thickness of heat insulating box 700 from existing 40mm (item 1 of table 1) is thinned to 30mm, as long as making the filling rate of Vacuumed insulation panel 400 is 40% Above and the Deflection Modulus of Elasticity of polyurethane is more than 15Mpa (item 4 of table 1), so that it may So that box deformation amount is less than prior art (item 1), heat insulating box 700 therefore can be made Casing intensity is more than existing parts (item 1).That is, even if reducing wall thickness (such as from 40mm It is reduced to 30mm), as long as by elastic to the filling rate of Vacuumed insulation panel 400 and the bending resistance of polyurethane Modulus is set as more than predetermined value, it is possible to improve heat-proof quality with not reducing casing intensity.Cause This, in the present embodiment, by using Deflection Modulus of Elasticity as Vacuumed insulation panel 400 The parts of more than 20MPa, and the filling rate of Vacuumed insulation panel 400 is set as more than 40%, The Deflection Modulus of Elasticity of hard polyurethane foams is set as more than 15MPa, though thinning heat insulation The wall thickness (being such as thinned to 30mm from 40mm) of casing, it is also possible to improve compared to existing technology The intensity of heat insulating box 700.

Additionally, the heat insulating box 700 of present embodiment is in position nonoverlapping with refrigerant piping 725 The inwall of the outer container 710 of (position the most in opposite directions) arrange the diameter with refrigerant piping 725 with On the resinous spacer of thickness, and make Vacuumed insulation panel 400 paste spacer, this Sample one, after making refrigerant piping 725 against the configuration of outer container 710 ground, can be true by being pasted with The spacer of empty thermal insulation barriers 400 in the way of covering refrigerant piping 725 directly with double faced adhesive tape etc. Paste outer container 710, it is easy to manufacture.The heat insulating box 700 of present embodiment is by vacuum heat-insulation Part 400 is configured to interior case 750 at predetermined spaced intervals, and is configured by Vacuumed insulation panel 400 Become with outer container 710 at predetermined spaced intervals, therefore become Vacuumed insulation panel 400 and be embedded in firmly Composition in matter polyurethane foam, heat-proof quality is improved.

As it has been described above, in the present embodiment, heat insulating box 700 can be at outer container 710 and interior In space 315 between case 750 foam filled so that Vacuumed insulation panel 400 be embedded in hard gather In urethane foam, between outer container 710 and Vacuumed insulation panel 400, there is condensation in the case of being somebody's turn to do and join The situation of pipe 725 is more, but can be by being configured to utilize the resinous spacers etc. such as EPS Make Vacuumed insulation panel 400 and outer container 710 have predetermined distance, configure Vacuumed insulation panel 400。

Additionally, Vacuumed insulation panel 400 is when becoming high temperature, easily absorb gas around, meeting The vacuum causing inside reduces, thermal conductivity deteriorates.In the case of the outer temperature height such as summer, The environment temperature (air themperature around) of outer container 710 uprises, the temperature of outer container 710 self It is likely to uprise, additionally, also become high temperature, therefore as the condensation pipe arrangement 725 that uses of pipe arrangement From the angle of the reliability guaranteeing Vacuumed insulation panel 400, preferably make Vacuumed insulation panel 400 away from Outer container 710, refrigerant piping (condensation pipe arrangement) 725.By make Vacuumed insulation panel 400 away from Outer container 710, refrigerant piping (condensation pipe arrangement) 725, can suppress Vacuumed insulation panel 400 because of Therefore the deterioration that temperature rises and causes, if making Vacuumed insulation panel 400 be floated by spacer etc. With away from the wall of outer container 710 or refrigerant piping 725, it is possible to suppression heat-proof quality Reduce, the high heat insulating box of reliability 700, refrigerator 1 can be provided for a long term.

Additionally, Vacuumed insulation panel 400 causes because absorbing gas (air etc.) around sometimes Internal vacuum declines, thermal conductivity deteriorates, but by be configured to by resinous for EPS etc. every Paste the ground such as outer container 710 from thing in hard polyurethane foams, bury Vacuumed insulation panel 400 underground, The amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore may be used Absorb gas (air etc.) around with suppression Vacuumed insulation panel 400, can suppress because of vacuum Reduction and the deterioration of Vacuumed insulation panel 400 that causes, can with long term maintenance high heat-proof quality, And heat insulating box 700 that reliability is high, refrigerator 1, equipment etc. can be provided.

Especially, in the heat insulating box 700 of present embodiment, hard polyurethane foams uses Density higher than the hard polyurethane foams that existing heat insulating box is used (density is more than 60kg/m³), therefore the bubble in hard polyurethane foams can correspondingly reduce density increase Amount, it is possible to reduce the amount (air capacity) of the gas in bubble.Therefore, so that Vacuumed insulation panel The mode that the surrounding of 400 is buried underground by hard polyurethane foams or covers is filled with or configures Time, it is possible to reduce the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400, because of This can suppress the reduction of vacuum of Vacuumed insulation panel 400, and (density of polyurethane is the biggest, poly- Space number in urethane is the fewest, and the air capacity in polyurethane is the fewest).Especially in the thickness of polyurethane When spending relatively thin (for example, during below 11mm), Vacuumed insulation panel 400 easily makes autohemagglutination ammonia The gases such as the air waited around ester enter, and therefore increase the density of polyurethane to reduce vacuum heat-insulation The gas flow of the surrounding of part 400 is bigger for the effect of the degradation inhibiting of Vacuumed insulation panel 400. Therefore, it can suppress further the deterioration of Vacuumed insulation panel 400, reliability can be provided for a long term High heat insulating box 700, refrigerator 1, equipment.

It addition, in the present embodiment with by condensation pipe arrangement 725 be configured in space 315 every It is illustrated as a example by hot tank body 700, but condensation pipe arrangement 725 be not configured at space 315 Interior heat insulating box 700 can certainly bury Vacuumed insulation panel in hard polyurethane foams underground 400.The amount of the gas of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore can suppress The deterioration of Vacuumed insulation panel 400, can be provided for a long term the high heat insulating box of reliability 700.

Here, do not form the orbit portion (track of the drawer of drawer type storeroom at interior case 750 Or recess etc.) 755 the heat insulating box 700 of composition, the situation etc. of refrigerator 1, interior case 750 During for being prone to the shape utilizing the directly stickup Vacuumed insulation panel 400 such as bonding agent or double faced adhesive tape, also All or part of of Vacuumed insulation panel 400 can be configured at interior case 750 side.

Here, as shown in the embodiment Vacuumed insulation panel 400 is being passed through PUR or two-sided In the case of the heat insulating box 700 of the composition that glue etc. are adhered directly onto interior case 750 side, it is possible to Lesser amount of Vacuumed insulation panel 400 provides energy-conservation and storeroom internal volume efficiency to compare prior art Heat insulating box 700 well, refrigerator 1.That is, at approximately parallelepiped body shape or the hot box of cylindrical shape In the case of body 700, in the surface area ratio of outer container 710, the surface area of case 750 is big, therefore exists When pasting Vacuumed insulation panel 400, Vacuumed insulation panel 400 ratio being bonded at interior case 750 surface is bonded at The Vacuumed insulation panel 400 on outer container 710 surface is few, therefore, it is possible to obtain low cost and heat-proof quality Heat insulating box well, refrigerator, showcase, hot water supply device, equipment.Additionally, such as pasting During the Vacuumed insulation panel 400 of formed objects, in the corner (example of rectangular-shaped heat insulating box 700 Such as the corner of the connecting portion as the back side of heat insulating box 700 and side or end face and side Corner or end face and the corner etc. at the back side), the vacuum of the wall that corner portion is adjacent one another are every Gap (Vacuumed insulation panel 400 of such as end face and the vacuum of adjacent side between warmware 400 Gap between thermal insulation barriers 400 or distance), Vacuumed insulation panel 400 is being configured at outer container During 710 side, bigger than when Vacuumed insulation panel 400 is configured at interior case 750 side.That is, by inciting somebody to action Vacuumed insulation panel 400 is configured at interior case 750, joins with by the Vacuumed insulation panel 400 of formed objects Compare when being placed in outer container 710, can reduce in adjacent Vacuumed insulation panel 400 shape each other The gap become, makes the heat waste caused because of heat leak correspondingly reduce the amount of gap shrinks, it is possible to carry For the good heat insulating box 700 of heat-insulating efficiency, refrigerator 1, hot water supply device, showcase, equipment.

Additionally, the heat insulating box 700 of present embodiment possesses at inner utilization partition wall The zonings such as 24 and the peristome of multiple storerooms 2,3,4,5,6 that formed carry out the hinge of opening and closing Connect the shutter door of formula or drawer type.It is (outer that this possesses the profile parts being made up of such as metal Plate) and the inner part (inner panel) that is made up of such as resin.Further, it is being formed at profile parts With configuration (filling) has hard polyurethane foams with true in the door inner space between inner part Empty thermal insulation barriers 400.Door is also based on the following technological thought illustrated by present embodiment and is formed : Vacuumed insulation panel is set in preset range and by very relative to the filling rate of heat insulating box Empty thermal insulation barriers 400 has the overwhelming majority of heat insulating function.Make the Vacuumed insulation panel of an inner space The filling rate of 400 is 40%～90%, covering rate is more than 70%.

When manufacturing this shutter door, by Vacuumed insulation panel 400 beforehand through the 2nd bonding agent etc. Be adhesively fixed profile parts, the raw material of liquid hard polyurethane foams is injected vacuum every The space between space, outer part and inner part between warmware and inner part, so that Profile parts, Vacuumed insulation panel 400, inner part can integral part of mode foam, Such that it is able to fill the hard polyurethane foams as foaming heat insulation part in door inner space.This Time, as long as the thickness of hard polyurethane foams is also to have the intensity as bonding agent, can Think more than 1mm preferably more than 3mm and below 11mm (preferably smaller than 10mm, more Preferably below 6mm).

It addition, for shutter door, exist and install for supporting at storeroom 2,3,4,5,6 The framework of containing box (storage box body 520) or the situation of door storage portion or shelf 80 etc., Thus exist and need the fixing screw of framework, the fixed component of door storage portion, the peace of shelf 80 Dress parts etc. utilize the secure components such as screw, fixed component, holding member fasten or keep Situation to the inner side (inside case) of shutter door.In this case, there is secure component, consolidate The situation that limiting-members, holding member are prominent to door inner space, if connecing with Vacuumed insulation panel 400 Touch, it is possible to the outsourcing material of Vacuumed insulation panel can be damaged, the most preferably in the inner side of shutter door So that thickness configuration or the filled polyurethane foam of Vacuumed insulation panel 400 will not be damaged.But, Need to be installed on the installation fitting (example of (inboard side) inside the storeroom of shutter door the most especially Such as secure component, fixed component, holding member etc.) time, it is also possible to by Vacuumed insulation panel 400 Paste inner panel.It addition, avoid installation fitting when arranging Vacuumed insulation panel, it is also possible to by vacuum Thermal insulation barriers pastes inner panel.

Additionally, there is profile parts (outside plate) and inner part (inner panel), be formed at wheel Door inner space between wide parts and inner part configures Vacuumed insulation panel 400, in profile portion Fill the hard as foaming heat insulation part between part or inner part and Vacuumed insulation panel 400 to gather In the case of urethane foam, if making the density of foaming heat insulation part more than 60kg/m³, then to being used for The fixed component i.e. screw etc. that the framework of support containing box (storage box body 520) is fixed Intensity or fixing intensity is kept to be improved, even if therefore receiving weight, Men Ye at box body 520 It is difficult to deform, can stably carry out the discrepancy of box body 520, it is possible to obtain the ice that reliability is high Case, equipment.Additionally, the guarantor of the fixed component i.e. screw etc. for miscellaneous parts such as fixed handles Hold intensity or fixing intensity is improved, therefore the doors such as the handle as miscellaneous part are being installed When parts are installed on, door installing component is improved to the installation strength of door, and therefore door is difficult to Deformation, can stably carry out the opening and closing of door, it is possible to obtain the high refrigerator of reliability, equipment. If additionally, making as foaming between profile parts or inner part and Vacuumed insulation panel 400 The hard polyurethane foams of thermal insulation barriers is more than 60kg/m³, then the bending resistance springform of foaming heat insulation part Amount is improved, and the intensity of door is also improved.

Here, Vacuumed insulation panel 400 can be configured at all of shutter door or a part of shutter door. Such as, when in exogenous QI and heat insulating box 700, temperature difference (such as in storeroom) is smaller (the such as storeroom of the refrigerated storage temperature band such as cold room 2, vegetable compartment 5), even if by vacuum heat-insulation Part 400 is configured at shutter door, and the effect that heat-proof quality is improved is the least.In this case, i.e. Make that Vacuumed insulation panel 400 is not configured to shutter door and can also ensure that the heat-proof quality of abundance.Very Empty thermal insulation barriers 400 temperature difference ratio (such as in storeroom) in exogenous QI and heat insulating box 700 Time bigger (storeroom of the cryogenic temperature band such as such as ice-making compartment 3, switch room 4, refrigerating chamber 6), If Vacuumed insulation panel 400 is configured at shutter door, then the effect that heat-proof quality is improved is bigger.Cause This, bigger cold of temperature difference (such as in storeroom) in exogenous QI and heat insulating box 700 In the case of freezing the storeroom of temperature band, by Vacuumed insulation panel 400 is configured at shutter door, May insure that the heat-proof quality of abundance.

Above, in the heat insulating box 700 of present embodiment or refrigerator 1 or equipment, phase Inside for the space 315 that will be formed between outer container 710 and interior case 750 and shutter door is empty Between i.e. door inner space spatial volume altogether, the volume ratio shared by Vacuumed insulation panel 400 I.e. the filling rate of Vacuumed insulation panel 400 within a predetermined range (such as more than 40% 80% with Under).Therefore, it can make wall thickness (the such as outer container 710 and interior case 750 of heat insulating box 700 Between distance and the thickness of shutter door) thinner than prior art, therefore, it is possible to provide energy-conservation and The heat insulating box 700 of the internal volume excellent in efficiency in storeroom, refrigerator 1, equipment.Therefore, even if Do not change heat insulating box 700 or the overall dimensions of refrigerator 1, it is possible to so that interior in storeroom Volumetric ratio is existing greatly, can increase the inside energy of heat insulating box 700 the most compared to existing technology The storage thing of enough storages.It is, therefore, possible to provide it is more energy-conservation than prior art and heat-proof quality good, business The costly heat insulating box of product 700, refrigerator 1, hot water supply device, showcase, equipment.

It addition, by the filling rate increasing the Vacuumed insulation panel 400 in space 315, space 315 The filling rate of interior hard polyurethane foams reduces.In the heat insulating box 700 of present embodiment, Make that the density of hard polyurethane foams is bigger than prior art (is greater than 60kg/m³), make hard The Deflection Modulus of Elasticity of polyurethane foam is the hard polyaminoester used than existing heat insulating box More than the 15.0MPa that the Deflection Modulus of Elasticity (about 6MPa～10MPa) of foam is big.Therefore, The heat insulating box 700 of present embodiment can also suppress the filling rate because of hard polyurethane foams Reduce the intensity caused to reduce, there is not heat insulating box 700 because tolerating because reserve is received Cause crooked of storage thing in space or storeroom or the weight of shutter door and the problems such as deformation, It is obtained in that heat insulating box 700 that reliability is high, refrigerator 1, equipment.

Therefore, at the refrigerator 1 of present embodiment or possess the heat insulation of band Vacuumed insulation panel 400 In the equipment of casing 700, heat insulating box 700 can be suppressed crooked and make shutter door inclination etc. open Close door cannot the situation of smooth and easy opening and closing, furthermore, it is possible to the deterioration of outward appearance that suppression causes because of deformation. Furthermore, it is possible to prevent shutter door and for sealing the contact of the sealing gasket of the peristome of heat insulating box The position relationship deviation in face (sealing surface) and produce gap so that air (ice in storeroom It is cold air in the case of case) situation of outflow outside heat insulating box.Thus, even if using in a large number Vacuumed insulation panel 400 can also suppress the performance of heat insulating box 700 to reduce, reliability reduces, There is excellent heat-proof quality, therefore can obtain energy-conservation and that reliability is high refrigerator or have The heat insulating box of Vacuumed insulation panel or possess the equipment of Vacuumed insulation panel, possess heat insulating box Equipment.

Here, heat insulating box 700 when for refrigerator be the height over width of above-below direction During the big elongated rectangular shape of the length in direction, compare the bottom surface sections of approximate horizontal configuration 780, the partition wall 24 etc. between top 740, storeroom, the sidewall 790 substantially vertically configured, Back face wall 730 is in elongated shape, and therefore rigidity is weak and be easily deformed.Therefore, by such as originally The filling rate of Vacuumed insulation panel 400, covering rate are so set in preset range by embodiment, The intensity (rigidity) of heat insulating box 700 can be improved.Additionally, by arrange protuberance 450 or Jut 910 can also improve casing intensity.Additionally, be arranged to make one end of protuberance 450 with It is configured at the Vacuumed insulation panel 400 of recess 440 or second recesses 441 with predetermined length X weight Folded, and the other end is connected to side surface part 790, such that it is able to make Vacuumed insulation panel 400 via Hard polyurethane foams is integrally formed with protuberance 450, furthermore, it is possible to make Vacuumed insulation panel 400 It is integrally formed with sidewall 790 via hard polyurethane foams, therefore can improve casing 700 Intensity.

Figure 21 is the side surface part 790 representing Vacuumed insulation panel 400 relative to heat insulating box 700 With the area ratio (back side, side covering rate) shared by the surface area of back part and box deformation amount The figure of relation, is result of calculation.About the intensity of heat insulating box, sidewall 790, back face wall 730 Be shaped as elongated oblong-shaped, with top wall 740, underside wall 780, partition wall 24 etc. Generally square shape phase specific rigidity more weak, therefore by by the back side, side of Vacuumed insulation panel 400 Covering rate is set as more than predetermined value, can improve casing intensity.Here, to Vacuumed insulation panel 400 relative to the area ratio (back side, side shared by the surface area of sidewall 790 and back face wall 730 Covering rate) illustrate with the relation of casing intensity.

In figure 21, transverse axis represents the Vacuumed insulation panel 400 sidewall relative to heat insulating box 700 790 and the area ratio (back side, side covering rate) shared by surface area of back face wall 730, longitudinal axis table Show the deflection of casing.Here, set the density of polyurethane as 60kg/m³, Vacuumed insulation panel 400 Filling rate be 40%, laterodorsal area ratio (back side, side covering rate) be case when 50% Body deformability amount is 1.The Deflection Modulus of Elasticity calculating the Vacuumed insulation panel 400 used is 20MPa, the measurement result of Deflection Modulus of Elasticity based on actually used Vacuumed insulation panel, make With bigger than the Deflection Modulus of Elasticity (about 6MPa～10MPa) of existing hard polyurethane foams Parts.Here, when changing area ratio (back side, side covering rate), Vacuumed insulation panel Filling rate is fixed as 40%, if the area ratio (back side, side covering rate) of therefore Vacuumed insulation panel Increase, then the thickness of Vacuumed insulation panel diminishes.

It addition, for calculate refrigerator 1 be an example, it is assumed that more than 4 (such as 4 or 5 or 6 specifications), internal volume is 500L level, consumes electric power and be about the ice of below 40W Case.Distance (wall thickness) average out to including the plate thickness between outer container 710 and interior case 750 30mm, it is assumed that outer container 710, the thickness of slab of interior case 750 are respectively 1mm, thus space 315 Thickness (thickness in wall) be 28mm.The density of hard polyurethane foams is 60kg/m³、 The thermal conductivity of Vacuumed insulation panel 400 is 0.0021 (W/m K), the leading of hard polyurethane foams Heating rate is 0.019 (W/m K), Vacuumed insulation panel 400 is heat insulation compared with hard polyurethane foams Performance has got well about about 10 times.

In figure 21, transverse axis represents that Vacuumed insulation panel 400 closes relative to side walls and back face wall The area ratio (laterodorsal Vacuumed insulation panel covering rate) shared by surface area come, the longitudinal axis represents The heat insulating box 700 with shutter door is applied with box deformation amount (case during predetermined load The amount of inclining of body).Here, the deflection of casing represents in the side of distance such as heat insulating box The above height and position of about about 1/4 of sidewall (laterally, is seen in front in a generally horizontal direction It is left and right directions when examining front openings portion) when being applied with predetermined load on the sidewall of heat insulating box The deflection of the left and right directions of end.

Understanding in figure 21, the area ratio of Vacuumed insulation panel 400 is the biggest, and box deformation amount is more Little.Make the area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side be 70% with Time upper, the rate of change of box deformation amount diminishes.That is, the area ratio to side/back side is 70% Till Zuo You, if area ratio becomes big, then box deformation amount drastically diminishes, but when side/back side Area ratio when becoming more than 70%, even if area ratio becomes big, box deformation amount is hardly Change.Therefore, the area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side When being more than 70%, the reduction ratio of the deflection of casing is minimum, though the side of Vacuumed insulation panel Backside area ratio increases, and box deformation amount changes the most hardly.This be considered as due to, The laterodorsal area ratio of Vacuumed insulation panel for the influence degree of casing intensity substantially close to full With.

Calculate here, make the filling rate of Vacuumed insulation panel be fixed as 40%, if therefore increasing true The configuration area of empty thermal insulation barriers 400, then the lower thickness of Vacuumed insulation panel 400.To vacuum every Till the area ratio at the side/back side of warmware is about 70%, if increasing the face at side/back side Long-pending ratio, then compared with the lower thickness of Vacuumed insulation panel and the increments of box deformation that causes, Because the configuration area of Vacuumed insulation panel becomes the casing change that the intensity raising of the casing caused greatly is caused The decrement of shape is bigger, and therefore the rigidity of casing improves, the deflection of casing reduces.But, When the area ratio at the side/back side of Vacuumed insulation panel exceedes about 70%, because of the thickness of Vacuumed insulation panel The intensity spending the thinning casing caused reduces the increments of the box deformation caused and because of vacuum Subtracting of the box deformation that the intensity raising of the casing that the configuration area change of thermal insulation barriers causes greatly is caused A small amount of is same degree, and the minimizing degree of the deflection of casing diminishes.

Additionally, make vacuum by increasing the configuration area ratio (covering rate) of Vacuumed insulation panel During the lower thickness of thermal insulation barriers, the thickness of polyurethane foam is thickening.To configuration area ratio it is Till about 70%, the thickness of Vacuumed insulation panel is more than predetermined thickness, therefore compare vacuum every The decrement of the thickness of warmware, the increments of area ratio is on the impact of the intensity of heat insulating box more Greatly, box deformation amount reduces, if but increase the configuration area ratio of Vacuumed insulation panel further, Then the thickness of Vacuumed insulation panel diminishes, and the thickness of polyurethane becomes big, thus the thickness of polyurethane The increments of the configuration area ratio of increments and the Vacuumed insulation panel shadow to the intensity of heat insulating box Ringing and become equal, the minimizing degree of box deformation amount diminishes.

Therefore, if (back side, side is coated to by the area ratio at the side/back side of Vacuumed insulation panel 400 Rate) it is set as more than predetermined value (70%), it is possible to obtain casing intensity, therefore, it is possible to obtain Obtain the casing that reliability is high.If additionally, the area ratio at the side/back side of Vacuumed insulation panel being set It is set to more than predetermined value (70%), then becomes the region that box deformation amount changes hardly, Even if therefore the configuration area of Vacuumed insulation panel produces inequality, the deflection of casing is sent out the most hardly Changing, therefore, it is possible to obtain high intensity, aesthetic appearance is good, reliability is high heat insulating box, ice Case, showcase, equipment.If making the covering rate of Vacuumed insulation panel 400 is more than predetermined value (60% It is set as that the 2nd makes a reservation for above) and by the area ratio at the side/back side of Vacuumed insulation panel 400 More than value (70%), then heat-proof quality improves, and can reduce box deformation amount, therefore It is obtained in that heat-proof quality is big, reliability is high and energy-conservation refrigerator, showcase, equipment.

If here, making the thickness of Vacuumed insulation panel fix and expand the configuration of Vacuumed insulation panel 400 Area, then the covering rate of Vacuumed insulation panel, filling rate all can increase, if but Vacuumed insulation panel The filling rate of 400 increases, then cost increases, and does not the most change filling rate and is coated to by increasing When rate improves the intensity of heat insulating box 700, cost is relatively low, and can increase Vacuumed insulation panel Configuration area, therefore heat-insulating efficiency improves.Therefore, by making filling out of Vacuumed insulation panel 400 The rate of filling is more than 40%, (laterodorsal Vacuumed insulation panel is coated to make the area ratio at side/back side Rate) it is more than 70%, it is possible to guarantee the intensity of heat insulating box with low-cost high-efficiency.Therefore, If by the area ratio at the side/back side of Vacuumed insulation panel, (laterodorsal Vacuumed insulation panel is coated to Rate) it is set as that the 2nd predetermined value (is the area that diminishes of the reduction ratio of the deflection of heat insulating box Ratio, for example, about 70%) more than, it is possible to the wall thickness of thinning heat insulating box 700 (subtracts The thickness of thin polyurethane), increase storeroom internal volume.Sidewall 790 and back face wall 730 true The configuration area (laterodorsal Vacuumed insulation panel covering rate) of empty thermal insulation barriers 400 is the biggest, heat insulation The deflection of casing 700 is the least, therefore can increase the intensity of heat insulating box 700, Ke Yiti For high intensity and the good heat insulating box 700 of heat-proof quality, refrigerator 1, possesses the equipment of heat insulating box.

(polyurethane physical property)

Here, physical property, the characteristic of the hard polyurethane foams being filled in heat insulating box 700 is entered Row explanation.Hard polyurethane foams is by increasing free foaming density, it is provided that after foaming The heat insulating box 700 that intensity stabilization, outward appearance are good, quality is high.

Here, free foaming density refers to, not in the airtight spaces such as casing, make polyurethane Foaming but hard polyurethane when making polyurethane foam in the container opened etc. under open mode The density of ester foam.And it practice, due to airtight narrow in heat insulating box 700 of polyurethane Foam in narrow space, expand, therefore foam in the airtight narrow spaces such as heat insulating box 700, The density of the polyurethane expanded, than the freedom of the polyurethane foaming in the open state, expanding Expansion density is big.

The density of the hard polyurethane foams after being foamed by raising is as illustrated in figure 16, permissible Increase Deflection Modulus of Elasticity, but fill out making polyurethane stock solution flow directly into heat insulating box 700 Filling when increasing density, the polyurethane that expansion ratio for currently using is little, free foaming is close Spend little to 26～28kg/m³, expansion ratio is little, if the stream of part of therefore polyurethane flowing It is not to there is size in thickness, then foaming degree is uneven, near inlet 703,704 and end Portion (away from the position of inlet) polyurethane density easily produces inequality, it is difficult to obtain stable Intensity.

In the present embodiment, by using free foaming density ratio existing (e.g., from about 25～28 kg/m³) (such as free foaming density is about 30～45kg/m to big hard polyurethane foams³), It is not that even if the stream thickness in the part of polyurethane flowing exists a little size, also due to foaming Multiplying power is big and can stably foam, and can reduce the inequality of the density after foaming.Therefore, easily The density of the polyurethane after making foaming is generally uniform.

The such foaming body of hard polyurethane foams, has bubble in inside, and density is the least, gas Steeping the most, heat insulation effect is the highest.Therefore, in prior art heat insulating box 700 make by Density after the foaming of the hard polyurethane foams used is about 25～28kg/m³Little density Hard polyurethane foams.Want to use this existing polyurethane foam to make the Deflection Modulus of Elasticity be When more than 15MPa is to guarantee the intensity of heat insulating box 700, such as in wall, thickness is 28mm In the case of, the thickness of polyurethane after the thickness removing Vacuumed insulation panel be 8mm every In hot tank body, it is necessary to inject, the lucky loading of packing ratio polyurethane is (to becoming object Poly-ammonia when will not apply irrational load etc. in casing and just fill hard polyurethane foams Ester amount, the density after foaming easily becomes uniform) how polyurethane, density easily produces inequality.

And then, due to the polyurethane that must inject, the lucky loading of packing ratio is many, it is therefore desirable to When polyurethane injects pressurization or extend the filling time, thus polyurethane from heat insulating box 700, The gaps (such as outer container 710 and the junction surface of interior case 750) such as the junction surface of the profile of shutter door Spill, it is impossible to the polyurethane of the scheduled volume needed for injection (cannot fill), it is difficult to guarantee to fill The density of the hard polyurethane foams after casing is than predetermined value (such as 60kg/mm³) big Density.If additionally, polyurethane spills from the profile of casing, it is necessary to remove the polyurethane spilt Operation, activity duration or built-up time need increase, cause cost raise, aesthetic appearance fall Low.Therefore, the density of the polyurethane after being filled into heat insulating box in prior art is less than 60kg/m³, about 25～30kg/m³, up to about 55kg/m³Below.
