In figure 27, same with Figure 24～Figure 26, the density of the thermal insulation barriers such as polyurethane 701 is more than 60kg/m³, therefore screw It is improved it is suppressed that the loosening, deviate or come off of screw etc. the holding intensity of fixed component 735 or fixing intensity.Additionally, The holding intensity of strengthening part 731 or fixing intensity are improved, can suppress the dislocation of strengthening part 731 generation, because Misplace the deformation of screw causing, the deformation of the orbit portion 755 of interior case 750, is obtained in that the high refrigerator of reliability, equipment.

Additionally, the thermal insulation barriers 701 such as polyurethane filled between the orbit portion 755 of Vacuumed insulation panel 400 and interior case 750 Thickness P is set to below 11mm (e.g., less than 10mm), is preferably below 6mm, therefore can increase the thermal insulation barriers such as polyurethane 701 Deflection Modulus of Elasticity, improves the intensity of casing 700 or refrigerator 1.Additionally, in strengthening part 731 and Vacuumed insulation panel Between 400, the thickness R of the thermal insulation barriers 701 such as polyurethane of filling is configured to, for example, about 6mm below less than predetermined thickness P, from And intensity can be improved further.

Additionally, in figure 27, the end (such as lower end) of the orbit portion 755 of interior case 750 is formed with interior case 750 to storeroom The protuberance 757 that side projects, is placed with the track supporting part 820 of track component 810 above this protuberance 757.This projects The prominent length of the width to storeroom side for the portion 757 is configured to the prominent length than track component 810 to width Little, interior is prominent to storing will not to compare track component 810, and the volume such that it is able to suppress reservoir volume, box body volume becomes Little.

Additionally, track supporting part 820 is that lower railway 812 passes through bodily forms such as welding with the trapped orbit of track component 810 Become, be thus susceptible to track component 810 is assembled into the orbit portion 755 of interior case 750.Additionally, track supporting part 820 is placed in Side above the protuberance 757 that the end (lower end) of orbit portion 755 is formed, and track component 810 is positioned to will not be downwards Mobile, additionally, side is provided with fixing by screw etc. or holding track supporting part 820 fixed part above protuberance 757, and By suppress track supporting part 820 or track component 810 upward or horizontal movement in the way of fix or be held in fixation Portion's (mobile suppressing portion).

Here, in Figure 24, Tu26Zhong, orbit portion 755 is located at partition wall 24 or the vicinity of underside wall 780, therefore rail Road part 810 is installed in partition wall 24 or the vicinity of underside wall 780, and box body 520 is propped up in the lower position of short transverse Support, the mounting intensity of therefore track component 810 is improved, thus preferably, and in Figure 25, Tu27Zhong, orbit portion 755 and separation Wall 24 or underside wall 780 have preset distance G, and therefore track component 810 can be with respect to partition wall 24 or underside wall 780 Top is installed on preset distance G such that it is able to make the Support Position of box body 520 be in top, can swimmingly carry out box body Discrepancy.Further, since the length of the box body supporting part 830 of track component 810 can be shortened, therefore intensity is improved, and And obtain the track component of low cost, refrigerator.

Here, box body stage portion 525, the box body support by track component 810 can be arranged in the box side wall of box body 520 Portion 830 supporting case body stage portion 525.Thereby, it is possible to easily support box body 520.Furthermore, it is possible to the height side in box body 520 To lower section or lower end (less than 1/2 preferably 1/3 position below of the such as height of box body 520) be supported, but If being supported to the back side of the box bottom wall as bottom, it is no need for arranging stage portion 525 it is easy to enter in box body 520 The manufacture of row box body 520.

Interior as the track mounting portion orbit portion end (orbit portion protuberance) 757 prominent to storeroom side being formed Thermal insulation barriers 701 (the such as rigid polyurethane foam such as polyurethane of filling between case 750 and Vacuumed insulation panel 400 (or outer container 710) Foam) density be more than 60kg/m³When, the intensity as the orbit portion end 757 of track component mounting portion is improved, and is therefore Make to receive weight in box body 520, the track component mounting portion of mounting track component 810 is that orbit portion protuberance 757 also will not become Shape, therefore can stably carry out the discrepancy of box body 520, be obtained in that the high refrigerator of reliability, equipment.

Here, track component 810 can located at side wall 790 it is also possible to located at configuration track component 810 storeroom point Next door (includes the partition wall of setting and the formation bottom surface of storeroom or partition wall above between storeroom and storeroom 24 or underside wall 780 or roof 740).I.e., it is possible to by the track supporting part 820 of supporting track part 810 located at (or It is placed in) partition wall (including partition wall 24 or roof 740 or underside wall 780).If so by supporting track part 810 Track supporting part 820, located at the partition wall 24 of storeroom, is no need for arranging fixed component 735 in side wall 790, therefore can increase In the thickness of the Vacuumed insulation panel 400 of side wall configuration, furthermore, it is possible to reduce the Vacuumed insulation panel 400 in side wall 790 and interior case The thickness of the thermal insulation barriers 701 such as polyurethane of filling between 750.Therefore, it can to increase the indoor volume of storage or box body 520 Volume.

Here, by track supporting part 820 in the case of partition wall, in partition wall 24 or underside wall 780 or In roof 740, the position configuration Vacuumed insulation panel 400 in setting track fixed component 735 is not advisable.If additionally, in setting rail The position of road fixed component 735 is provided for the strengthening part of the fixed components such as fixing screws, then the fixing intensity of fixed component Or keep intensity to be improved.Additionally, filling or the painting and the profile parts forming partition wall between in Vacuumed insulation panel 400 When applying or configuring the thermal insulation barriers such as hard polyurethane foams or foam styrene, if making the density of thermal insulation barriers be more than 60kg/m³, Then fixed component that is fixing or keeping track component 810 or the holding of strengthening part or fixing intensity are improved, therefore Reliability improves.

Above to the situation fixing the orbit portion 755 of interior case 750 inside storeroom with screw etc. (as fixed component The head of screw of 735 screw located at storeroom 2,3,4,5,6 side, fixed component 735 threaded portion located at interior case 750 orbit portion Situation between 755 and Vacuumed insulation panel 400) it is illustrated.But the screw 735 that can also make fixed component is from side wall 790 Laterally therein storeroom 2,3,4,5,6 in prominent and fixing, now, head of screw is located at Vacuumed insulation panel 400 and interior case 750 Between orbit portion 755 (thermal insulation barriers such as orbit portion 755 or track strengthening part 731 or polyurethane 701 are fixed in threaded portion), but Even if in this case, because the density of polyurethane is more than 60kg/m³, the therefore fixation such as the intensity increase of polyurethane 701, screw The fixing intensities of thermal insulation barriers 701 such as the thermal insulation barriers such as part 735 and polyurethane 701, interior case 750 and polyurethane or holding intensity increase Plus, thus the deformation of interior case etc., the dislocation of strengthening part 731, screw loosen etc. be suppressed, box body 520 grade can be made swimmingly Pull-out (can swimmingly come in and go out).

In embodiments of the present invention, by the interior case of the position opposite with the position of the setting track component of side wall 790 The thickness of the foaming heat insulation part (such as hard polyurethane foams) between 750 and Vacuumed insulation panel 400 is set as that below 11mm is (excellent Choosing is less than 10mm), such that it is able to increase the Deflection Modulus of Elasticity of polyurethane, therefore can be thinning while maintaining the intensity of wall Wall thickness.Additionally, by with the interior case 750 and Vacuumed insulation panel 400 of the opposite position in position of the setting track component of side wall 790 it Between the thickness of foaming heat insulation part (such as hard polyurethane foams) when being set as below 6mm, polyurethane can be increased further Deflection Modulus of Elasticity, therefore can maintain wall intensity while thinning wall thickness.

Additionally, by being set as the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) Less than 0.3, the composite guide heating rate of the composite component that foaming heat insulation part and Vacuumed insulation panel are combined can be reduced, be therefore Make thinning wall thickness also can improve heat-proof quality.

Additionally, the density after making polyurethane foam is more than 60kg/m³, can be thinning while maintaining the intensity of wall Wall thickness.

As above, in embodiments of the present invention, in the opposite position in the position of the setting track component with side wall 790 The thickness of the foaming heat insulation part (such as hard polyurethane foams) between interior case 750 and Vacuumed insulation panel 400 is that below 11mm is (excellent Choosing be less than 10mm), by the thickness of foaming heat insulation part/(thickness of the thickness+Vacuumed insulation panel of foaming heat insulation part) be set as 0.3 with Under, and make the density after polyurethane foam be more than 60kg/m³When, can further maintain wall intensity while thinning wall Thick.Here, the thickness of the foaming heat insulation part in above formula is the thickness of polyurethane, accordingly, as the thickness of foaming heat insulation part, permissible Be filling between the orbit portion 755 of Vacuumed insulation panel 400 and interior case 750 the thickness P of thermal insulation barriers 701 such as polyurethane or The thickness Q of thermal insulation barriers 701 or the Vacuumed insulation panel 400 such as polyurethane of filling between Vacuumed insulation panel 400 and interior case 750 The thickness R of the thermal insulation barriers such as the polyurethane and strengthening part 731 between 701.For example, the thickness making foaming heat insulation part is vacuum heat-insulation During the thickness R of the thermal insulation barriers such as the polyurethane between part 400 and strengthening part 731 701, by the thickness R/ (foaming of foaming heat insulation part The thickness of the thickness R+ Vacuumed insulation panel of thermal insulation barriers) it is set as less than 0.3.Equally, when to make thickness be P or Q, by 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 equally in Vacuumed insulation panel The thickness P of thermal insulation barriers 701 such as polyurethane of filling between 400 and the orbit portion 755 of interior case 750, in Vacuumed insulation panel 400 and interior The poly- ammonia between the thickness Q of thermal insulation barriers 701, Vacuumed insulation panel 400 and strengthening part 731 such as polyurethane of filling between case 750 The thickness R of the thermal insulation barriers such as ester 701.

If additionally, making the Deflection Modulus of Elasticity of Vacuumed insulation panel 400 be more than 20MPa, can thinning wall thickness further.? This, can not be and for track component to be fixed to side wall 790, and is secured to underside wall 780 near side wall 790 or bottom surface Partition wall 24 or upper wall (roof) 740 or partition wall 24 above.Here, in the portion with fixed components such as setting screws When not configuring Vacuumed insulation panel 400 between the opposite interior case 750 in position and outer container 710, the underside wall 780 of setting fixed component or Wall or partition wall that following partition wall 24 or roof 740 or partition wall above 24 are not preferably contacted with outer gas. In the wall (such as side wall 790, roof 740, back face wall 730, underside wall 780 etc.) contacting with outer gas, minimizing is not provided with vacuum as far as possible The position of thermal insulation barriers 400, can reduce the loss causing because of heat leak, therefore, it is possible to obtain high performance heat insulating box, refrigerator, Equipment.Thereby, it is possible to increase the configuration area of the Vacuumed insulation panel 400 of back face wall 730, side wall 790, heat-insulated therefore, it is possible to increase The covering rate of Vacuumed insulation panel 400 in casing 700 or filling rate.

Here, the heat insulating box 700 of present embodiment 1, mainly undertake with the hard polyurethane foams in heat insulating box 700 This prior art thought of heat insulating function is different, and it makes Vacuumed insulation panel 400 based in the part being configured with Vacuumed insulation panel 400 Undertake heat-proof quality and this new technological thought of casing intensity.Therefore, the heat insulating box 700 of present embodiment 1 makes outside The filling rate of the Vacuumed insulation panel 400 in space 315 in the wall being formed between case 710 and interior case 750 be (Vacuumed insulation panel 400 Volume is with respect to the ratio shared by the cumulative volume in space 315 in the wall being formed between outer container 710 and interior case 750) it is predetermined value Above (for example, more than 40% (preferably more than 45%)).Here, the filling rate of Vacuumed insulation panel 400 also includes vacuum heat-insulation In door between the external door panel of the profile with respect to formation door for the volume of part 400 and door inner panel, the ratio shared by volume in space is The filling rate of door.

In prior art, so that Vacuumed insulation panel is with respect to the area ratio shared by the surface area of outer container 710 or interior case 750 Example (covering rate) mode within a predetermined range configures Vacuumed insulation panel, and do not consider the thickness of Vacuumed insulation panel 400 Impact, therefore makes the thickness of hard polyurethane foams bigger than the thickness of Vacuumed insulation panel 400, to have by hard polyaminoester The intensity of heat insulating box.The heat-proof quality to improve casing for the covering rate of Vacuumed insulation panel 400 to be increased in prior art, but simultaneously Do not increase the filling rate of Vacuumed insulation panel 400 to improve heat-proof quality and casing intensity both sides, therefore the filling out of Vacuumed insulation panel 400 , there is the situation that heat-proof quality does not improve, and casing be strong in rate of filling less (filling rate in for example existing refrigerator is about 20%) Degree depends on hard polyurethane foams.In the present embodiment, to consider the side of the filling rate of the thickness of Vacuumed insulation panel 400 Formula configuring Vacuumed insulation panel 400, thus without not improving heat-proof quality as prior art.By making Vacuumed insulation panel 400 filling rate is more than predetermined value (such as more than 40%), and heat-proof quality is improved, and can be to meet casing strong Thinning wall thickness while degree, heat-proof quality, therefore, it is possible to increase storage chamber volume, can be indoor by the storage required by product Volume settings are more than predetermined capacity.I.e., it is possible to suitably set the length of Vacuumed insulation panel 400, width, thickness, configuration Position, can reduce wall thickness, can correspondingly increase storage chamber volume.

By so increasing the filling rate of the Vacuumed insulation panel 400 in space 315 compared to existing technology so that heat-proof quality Increase compared to existing technology, though therefore compared to existing technology the wall thickness of thinning heat insulating box 700 it is also possible to guarantee heat-insulated Performance is more than the equal extent of prior art.

(other compositions of the 1st wind path accessory)

As mentioned above, in embodiments of the present invention, for example the formation cold air shown in Fig. 4, Fig. 5, Fig. 6, Fig. 8 etc. The width length of the 1st wind path accessory 762 of a part for wind path 760 is less than the width of recess 440, in protuberance 450 or the Jut 910 of 2 recesses 441 or formation second recesses 441 etc. by the fixed components such as screw or hooking structure or is fitted together to Structure etc. is fixed or keeps.Here, the width of the 1st wind path accessory 762 of a part for formation cold air wind path 760 can be made Direction length reaches the inner face of side wall 790 and by the 1st wind in the way of covering a part for back face wall 730 or side wall 790 Road accessory 762 passes through the fixed components or hooking structure or embedded structure etc. such as screw to be fixed or remains to the interior of side wall 790 Face.Certainly, the 1st wind path accessory 762 not only can be fixed or remain to the inner face of side wall 790, can also by fixed component or Jut 910, recess 440, protuberance 450 etc. are fixed or remained to person's hooking structure or embedded structure etc..

If additionally, making the width length of the 1st wind path accessory 762 of a part for formation cold air wind path 760 reach The inner face of side wall 790 also covers recess 440, at least a portion of protuberance 450 or whole thus not only covering second recesses 441, Then the 1st wind path accessory 762 can be also used as the Appearance Panel, can cover the back face wall of room (such as storeroom) or side wall At least a portion of inner face or all, can using the 1st wind path accessory 762 as the part covering the back side or side cover Part uses.Therefore, by indoor supply be derived from cold air wind path 760 cold air supply mouth located at the 1st wind path accessory 762 When, the free degree of configuration can be improved, efficiently cool down interior storage item, additionally, the 1st wind path accessory 762 can use with The different another part of interior case 750, therefore can easily change shape or color or carry out a variety of processing, coating or word Record etc., feature, aesthetic appearance are improved.1st wind path accessory is also used as the Appearance Panel and as cap assembly use when, shape Become substantially U-shaped and cover the back face wall 730 of forming chamber and at least a portion of inner face of side wall 790 or wall All inner face is advisable.Now, lighting device (case intraoral illumination) is if 900 are configured at roof 740 or the underside wall 780 of forming chamber, Then when making to reach side wall 790 as the 1st wind path accessory 762 of cap assembly, with by lighting device 900 in side wall 790 The situation in face is compared, and need not excise or arrange opening by the 1st wind path accessory 762 being provided with the part of lighting device 900, therefore make The shape of the Appearance Panel (the 1st wind path accessory 762) for cap assembly becomes easy, is obtained in that heat insulating box, the ice of low cost Case, equipment.Here, the Appearance Panel as cap assembly can be formed as covering the roof 740 of forming chamber and back face wall 730 extremely A few part or whole inner face side of wall.

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

Here, the relation of the intensity of filling rate to Vacuumed insulation panel 400 and casing illustrates.Figure 15 is to represent hard The figure of the relation of the density of polyurethane foam and thermal conductivity, Figure 16 is density and the bending resistance springform representing hard polyurethane foams The figure of amount, Figure 17 is the relation of the thermal conductivity representing the stream thickness of polyurethane when being filled with hard polyaminoester and polyurethane Figure, Figure 18 is the relation of the Deflection Modulus of Elasticity representing the stream thickness of polyurethane when being filled with hard polyaminoester and polyurethane Figure.Figure 15～Figure 18 is the mould filled hard polyaminoester between two faces with predetermined gap (stream) and make it foam Intend the experimental result under structure, the face of the side of stream be as the 1st part steel plate (for example formed Vacuumed insulation panel or The profile of the heat insulating box 700 of refrigerator 1 is the coated steel plate of outer container 710), the face of the opposite side of stream is as the 2nd part Resin (ABS (acrylonitrile, butadiene, cinnamic copolymerization resin) that for example, interior case 750 is used, (mould EPS by foaming Material) etc. resin).

In Figure 15, transverse axis represents the density (kg/m of hard polyurethane foams³), the longitudinal axis represents leading of hard polyurethane foams Heating rate [W/ (m K)].Additionally, in Figure 16, transverse axis represents the density (kg/m of hard polyurethane foams³), the longitudinal axis represents that hard gathers The Deflection Modulus of Elasticity (MPa) of urethane foam.In Figure 17, transverse axis represents the stream thickness (mm) of 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 hard polyurethane foams Stream thickness (mm), the longitudinal axis represents the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.Here, filling rigid polyurethane foam The stream thickness of foam represents the thickness of filling hard polyurethane foams the hard polyurethane foams of the state having foamed in stream Degree.

According to Figure 15, Figure 16, hard polyurethane foams thermal conductivity, Deflection Modulus of Elasticity when density is bigger is bigger, close Degree more hour thermal conductivity, Deflection Modulus of Elasticity is less.That is, density and thermal conductivity or density and Deflection Modulus of Elasticity be essentially just The relation of ratio.

According to Figure 17, Figure 18, hard polyurethane foams (or are filled hard in the stream thickness of filled polyurethane in stream The thickness of the polyurethane of matter polyurethane foam the state having foamed) narrower when thermal conductivity bigger, additionally, Deflection Modulus of Elasticity Bigger.Therefore, the thickness of the polyurethane after foaming in stream is thicker, and thermal conductivity is less, and heat-proof quality is higher, but bending resistance is elastic Modulus is less, and intensity is lower.Therefore, when the thickness of polyurethane to be reduced is with thinning wall thickness, Deflection Modulus of Elasticity increases, and therefore exists Have no problem in intensity, but thermal conductivity becomes too much, heat-proof quality deteriorates, the thickness of polyurethane therefore cannot be made to be less than certain journey Degree (such as 15mm).

Here, in Figure 17, Tu18Zhong, if the stream thickness of filled polyurethane (or the polyurethane after foaming in stream Thickness) narrow, then density increases, if density increases, thermal conductivity increases as shown in figure 15, and heat-proof quality deteriorates.Here, as schemed Shown in 17, if the stream thickness of filled polyurethane (or thickness of the polyurethane after foaming in stream) becomes predetermined thickness (example As 11mm) below, then thermal conductivity is increased dramatically, and heat-proof quality deteriorates.Hard polyurethane foams are forming the 1st of polyurethane stream Foaming solidification in the state of bonding to the 1st part and the 2nd part between part and the 2nd part, now, polyurethane forms core Layer simultaneously forms the boundary layer being referred to as cortex in the both sides (the 1st component side and the 2nd component side) of this sandwich layer.

Figure 23 A and Figure 23 B is the schematic diagram of the cross sectional shape after hard polyurethane foams foaming, and Figure 23 A is to represent the 1st Part (interior case 750) is filled with the schematic diagram in section during hard polyurethane foams 701A and the 2nd part (outer container 710) between, Figure 23 B is to represent to be folded with the 3rd part (Vacuumed insulation panel in the 1st part (interior case 750) and the 2nd part (outer container 710) between 400) schematic diagram in section when being filled with hard polyurethane foams 701A between the 1st part and the 3rd part when.

In Figure 23 A, the thermal wall possessing foam filled polyurethane between the 1st part and the 2nd part is successively by the 1st Part (for example interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 2nd part (such as outer container 710) are constituted. On the other hand, as shown in fig. 23b, configure as the 3rd part and the 2nd part (outer container 710) between in the 1st part (interior case 750) During Vacuumed insulation panel 400, thermal wall is successively by the 1st part (interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 3rd part (Vacuumed insulation panel 400), the 2nd bonding agent 715, the 2nd part (outer container 710) are constituted.In addition, the 1st cortex 701B, sandwich layer 701C and the 2nd cortex 701D constitute hard polyurethane foams 701A.

Cortex is formed at the 1st nearby components or the 2nd nearby components or the 3rd nearby components, the stream thickness of polyurethane The scope that (thickness of polyurethane) uses for prior art i.e. about 20mm～30mm when, the thickness of cortex is with respect to the thickness of sandwich layer Sufficiently small, to density, thermal conductivity etc. impact very little, if but the thickness of polyurethane be predetermined thickness (such as 11mm) below, The thickness of cortex becomes big with respect to the ratio shared by the thickness of sandwich layer, to the density of polyurethane, thermal conductivity, Deflection Modulus of Elasticity Impact is increased dramatically, and density, thermal conductivity, Deflection Modulus of Elasticity drastically become big.Therefore, heat-proof quality drastically deteriorates.Additionally, as schemed Shown in 18, the density due to polyurethane rises, and the Deflection Modulus of Elasticity of polyurethane also steeply rises.

Therefore, in prior art, if reducing the thickness of polyurethane, Deflection Modulus of Elasticity increases, intensity improves, but poly- ammonia The thermal conductivity of ester rises, heat-proof quality deteriorates, and therefore cannot reduce the thickness of polyurethane, and the scope in about 15mm～30mm makes With.In prior art, with polyurethane based on, thermal insulation barriers, Vacuumed insulation panel, for assisting the mode of thermal insulation barriers to be configured, therefore exist The heat-proof quality of polyurethane thermal insulation barriers will not deteriorate in the range of determine polyurethane thickness, even if also ensuring that in narrow part About 15mm～20mm.

But, in the present embodiment, thermal insulation barriers and casing is obtained by Vacuumed insulation panel based on Vacuumed insulation panel The mode of intensity does not require heat-proof quality forming thermal wall, the hard polyaminoester being therefore configured with the part of Vacuumed insulation panel, Even if thus also having no problem below for predetermined thickness (such as 11mm, preferably 6mm), more thin then Deflection Modulus of Elasticity rising, Casing intensity improves, therefore better.When predetermined thickness is below 11mm, the impact to sandwich layer of the thickness of cortex becomes big, heat conduction Rate is increased dramatically, and heat-proof quality drastically reduces, be therefore difficult in prior art to make hard polyurethane foams thickness be 11mm with Under.In prior art, with regard to the thickness of hard polyurethane foams, though local small range can make predetermined value be 11mm with Down it is also difficult to make average thickness be below 11mm.And then, if predetermined thickness is below 6mm, the thickness of cortex is to sandwich layer Impact increase further, heat-proof quality more deteriorates, and is therefore difficult with prior art.But in the present embodiment, make Vacuumed insulation panel 400 has the heat-proof quality of heat insulating box 700, even if the thickness of therefore thinning polyurethane is not also asked to use Topic.Therefore, in the present embodiment, by being set as below 11mm (preferably smaller than the thickness of hard polyurethane foams 10mm), can increase hard polyurethane foams Deflection Modulus of Elasticity, improve casing 700 intensity (rigid).If additionally, will The thickness of hard polyurethane foams is set as below 6mm, can increase the Deflection Modulus of Elasticity of hard polyurethane foams further, The intensity (rigid) of therefore casing 700 is further enhanced.

In addition, in the part not configuring Vacuumed insulation panel 400, the thickness of polyurethane can be with the thickness of Vacuumed insulation panel (e.g., from about 15mm～30mm) is formed thicker, and the thickness of therefore polyurethane may insure about 20mm～40mm, can not be poly- The scope (below thickness 11mm of polyurethane) that the thermal conductivity of urethane steeply rises uses, can be upper in the thermal conductivity of polyurethane The little scope (thickness of such as polyurethane is the scope of such as more than 15mm) of the degree of liter (slope) uses, even if therefore considering poly- The uneven thickness of urethane can also ensure that the heat-proof quality of polyurethane is below predetermined value.Therefore, it can meet heat insulating box 700 Intensity and heat insulating box 700 heat-proof quality both sides.

Here, the 1st part using in the face of the side of polyurethane stream, using resin, (for example, interior case 750 is used ABS (acrylonitrile, butadiene, cinnamic copolymerization resin) or EPS (resin such as foamed plastic)).Stream another The face of side is used the aluminium-vapour deposition film of the outsourcing material as Vacuumed insulation panel, forms the steel such as the coated steel plate (PCM) of outer container 710 Plate.

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

Figure 19 is to represent that wall thickness (thickness between the inwall of wall) is fixed as the thickness of polyurethane during 27mm with respect to by vacuum The figure of the relation of the ratio of the thickness of the thermal insulation barriers of thermal insulation barriers and polyurethane composition and composite guide heating rate.In Figure 19, horizontal Axle represents the thickness of polyurethane with respect to by the ratio of the thickness of the thermal insulation barriers of Vacuumed insulation panel and polyurethane composition, gather The thickness of urethane/(thickness of polyurethane+Vacuumed insulation panel thickness), the longitudinal axis represents composite guide heating rate (by Vacuumed insulation panel and poly- The thermal conductivity that urethane combines).Here, total, the i.e. polyurethane by the thickness of the thickness of polyurethane and Vacuumed insulation panel The thickness of thickness+Vacuumed insulation panel is as thickness in wall.

It appears from figure 19 that with respect to thickness in wall, when the thickness of polyurethane is less, composite guide heating rate diminishes, heat-proof quality Improve.Here, composite guide heating rate represents the thermal conductivity of the composite component combining polyurethane and Vacuumed insulation panel.In figure, In the thickness/wall of polyurethane, thickness changes with 0.3 for boundary's slope, is more than 0.3 phase with thickness in the thickness/wall of polyurethane In the thickness/wall of polyurethane, when about less than 0.3, slope is less for thickness, and the ratio of the reduction of composite guide heating rate is less for ratio.Figure For the experimental verification of thickness in wall one timing, therefore in the thickness/wall of polyurethane, the ratio of thickness is less, and the thickness of polyurethane is got over Little, on the contrary the thickness of Vacuumed insulation panel is bigger, and the therefore thickness of Vacuumed insulation panel is bigger with respect to the ratio shared by thickness in wall. That is, with respect to thickness in wall, the thickness of polyurethane becomes hour, and the thickness of Vacuumed insulation panel is with respect to the ratio of the thickness of polyurethane Increase.In figure, in the thickness/wall of polyurethane, thickness is at about 0.6, and the thickness of polyurethane is bigger than the thickness of Vacuumed insulation panel, The impact to composite guide heating rate (Vacuumed insulation panel and polyurethane thermal conductivity altogether) for the thermal conductivity of therefore polyurethane is larger, multiple Close thermal conductivity also larger (heat-proof quality is poor).If reducing thickness in the thickness/wall of polyurethane, the thickness of Vacuumed insulation panel is relatively Ratio in the thickness of polyurethane increases, and therefore compares the thermal conductivity of polyurethane, the thermal conductivity of Vacuumed insulation panel is to composite heat-conducting Rate impact larger as a result, thickness/(thickness of the thickness+Vacuumed insulation panel of polyurethane) with polyurethane diminishes, polyurethane The thermal conductivity (composite guide heating rate) of the composite component combining with Vacuumed insulation panel reduces.Here, until polyurethane thickness/ When (thickness of the thickness+Vacuumed insulation panel of polyurethane) is about 0.3, compare the thermal conductivity of polyurethane, the heat conduction of Vacuumed insulation panel The impact to composite guide heating rate for the rate is larger, and the reduction ratio of therefore composite guide heating rate is also larger, the thickness/(polyurethane of polyurethane Thickness+Vacuumed insulation panel thickness) less, composite guide heating rate is less, and heat-proof quality is greatly improved.

But, from the thickness of polyurethane with respect to the ratio of thickness in wall, i.e. polyurethane thickness/(thickness of polyurethane+ The thickness of Vacuumed insulation panel) less than about 0.3 when from, the slope of the reduction of composite guide heating rate changes, the fall of composite guide heating rate Low slope diminishes (ratio of the reduction of composite guide heating rate diminishes).This is considered as because the thickness of polyurethane is with respect to wall In the thickness/wall of the ratio of interior thickness, i.e. polyurethane, thickness diminishes, thus with respect to composite component (by polyurethane and vacuum every The part that warmware combines) heat-proof quality, the heat-proof quality of Vacuumed insulation panel becomes overriding, the thermal insulation of polyurethane Can the impact to the heat-proof quality of composite component diminish.Therefore, in the present embodiment, by composite component (polyurethane and true The heat insulating member of the adjacent formation of empty thermal insulation barriers both sides) thermal wall that formed so that in the thickness/wall of polyurethane thickness be 0.3 with Under mode set polyurethane thickness when, the ratio of the reduction of heat-proof quality diminishes, though therefore the thickness of polyurethane or The thickness of Vacuumed insulation panel produces inequality, and the inequality of heat-proof quality also can be made less, therefore preferably.Conversely, can also be by vacuum In the thickness/wall of thermal insulation barriers, thickness is set as more than 0.7.

Therefore, set in the way of in the thickness/wall making polyurethane, thickness is about less than 0.3 polyurethane thickness when, can To reduce composite guide heating rate, the heat-proof quality of composite component is largely increased.If additionally, considering the inequality of the thickness of polyurethane (or inequality of the thickness of Vacuumed insulation panel) is set so that thickness is in less than 0.3 model in the thickness/wall of polyurethane In enclosing, even if then the thickness of polyurethane, the thickness of Vacuumed insulation panel produce uneven it is also possible to suppress the heat-proof quality of composite component Reduction, and the inequality of the composite guide heating rate of composite component can be suppressed, therefore, it is possible to obtain reliability high, high performance every Hot wall, heat insulating box, refrigerator, equipment etc..

Figure 20 is to represent that the volume of Vacuumed insulation panel 400 is vacuum with respect to the ratio shared by the volume in space in wall 315 The filling rate of thermal insulation barriers and the figure of the relation to the deflection of heat insulating box during heat insulating box 700 imposed load (load).? In Figure 20, transverse axis represents that the filling rate of Vacuumed insulation panel, the longitudinal axis represent the deflection of heat insulating box.Here, Vacuumed insulation panel Filling rate is the ratio (ratio) that Vacuumed insulation panel 400 is with respect to the volume shared by the volume in the space 315 in wall, heat insulating box Deflection be left on the side of casing about 1/4 in the state of having door in the such as heat insulating box of refrigerator 1 grade Right height and position in a generally horizontal direction (being left and right directions when laterally, observing front openings portion in front) be applied with predetermined The result of calculation of the deflection in left and right directions (horizontal) for the upper end position of the side wall 790 of the casing 700 during load, if vacuum every The filling rate of warmware 400 is deflection when 20% is 1.Figure 20 is to make the covering rate (such as 65%) of Vacuumed insulation panel, poly- ammonia Ester density (such as 60kg/m³), the Deflection Modulus of Elasticity (such as 9MPa) of polyurethane, the Deflection Modulus of Elasticity of Vacuumed insulation panel Wall thickness (such as 30mm) that the thickness (such as 28mm) of (such as 15MPa), composite component, outer container are added with the thickness of interior case etc. is solid Determine and make the thickness change of Vacuumed insulation panel with change Vacuumed insulation panel filling rate when result.

In fig. 20, the filling rate of Vacuumed insulation panel is bigger, and box deformation amount is less.This be considered as due to, vacuum every The Deflection Modulus of Elasticity of warmware is bigger than the Deflection Modulus of Elasticity of polyurethane, thus the volume of adjoint Vacuumed insulation panel is with respect to heat-insulated The ratio of the polyurethane volume in casing increases, and the impact of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes big, the rigidity of casing 700 Increase.When the filling rate of Vacuumed insulation panel 400 is more than 40%, the reduction ratio of the deflection of casing becomes minimum, even if very The filling rate of empty thermal insulation barriers increases, and box deformation amount also hardly changes.This is considered as due to Vacuumed insulation panel 400 For casing intensity (deformation of casing) influence degree substantially close to saturation.

The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is bigger than hard polyurethane foams, therefore passes through to increase Vacuumed insulation panel 400 volume, with respect to the ratio (ratio) (increasing the filling rate of Vacuumed insulation panel) shared by the volume in space 315, can contract The deflection of little heat insulating box 700, therefore, it is possible to improving the heat-proof quality of heat insulating box 700, increasing heat insulating box 700 or ice The casing intensity of case 1 or equipment.Now, if increase Vacuumed insulation panel 400 thickness come to increase filling rate it becomes possible to realize Improve heat-proof quality while the effect that the intensity of casing improves.Here, can be increased by increasing the thickness of Vacuumed insulation panel The filling rate of big Vacuumed insulation panel is it is also possible to pass through to increase the surface area with respect to casing 700 for the surface area of Vacuumed insulation panel 400 Ratio (covering rate of Vacuumed insulation panel) to increase the filling rate of Vacuumed insulation panel, now can also increase the intensity of casing, And, by increasing the covering rate of Vacuumed insulation panel 400, the filling rate of Vacuumed insulation panel can be increased.If additionally, increasing vacuum The covering rate of thermal insulation barriers 400, then configuration scope (configuration position) increase of Vacuumed insulation panel, can be with thinning heat insulating box 700 Wall thickness, therefore can make storeroom internal volume increase the amount of wall thickness reduction.

In the present embodiment, for example, in outer container 710 and the storage forming heat insulating box of the profile forming heat insulating box At least a portion in the space 315 between the interior case 750 of a part for the inwall of room possesses Vacuumed insulation panel 400, makes space 315 The filling rate of interior Vacuumed insulation panel 400 is more than 40%, and makes the surface area that Vacuumed insulation panel 400 is with respect to outer container 710 Area ratio (covering rate) be more than 60% such that it is able to obtain that heat-proof quality is high, casing intensity is also big and reliability is high every Hot tank body, refrigerator, equipment etc..Here, in the present embodiment, it is configured to by Deflection Modulus of Elasticity than existing heat insulating box institute With the high Vacuumed insulation panel 400 of hard polyurethane foams undertake the wall intensity of heat insulating box 700, therefore, it is possible to simultaneously full Sufficient casing intensity and heat-proof quality, and can thinning wall thickness, therefore storage chamber volume also can increase.

The heat insulating box 700 of present embodiment passes through the bending strength Vacuumed insulation panel higher than hard polyaminoester 400 Filling rate is set as more than predetermined value (or in preset range) or will be double to the filling rate of Vacuumed insulation panel 400 and covering rate Side is set as more than predetermined value (or in preset range), can meet heat-proof quality and casing intensity and can be thinning simultaneously The wall thickness of heat insulating box 700.Therefore, storage interior can be expanded without the appearance and size of change heat insulating box 700, refrigerator 1 Internal volume, can increase the storage item that can store in the inside of heat insulating box 700 or refrigerator 1 or equipment, reserve. In addition, during wall intensity decreases it may occur that heat insulating box 700 deform, for example, fall located at internal shelf 80 offset track portion, Or the sliding of the storeroom (or the door of drawer type or box body or shutter door etc.) of drawer type is the problems such as be deteriorated.But at this In embodiment, due to the filling rate of Vacuumed insulation panel 400 and/or covering rate being set as more than predetermined value (preset range Interior), therefore with the wall thickness of thinning heat insulating box 700, and can improve casing intensity and heat-proof quality, therefore, it is possible to suppress The generation of situations below：Shelf 80 offset track portion and fall, or drawer type storeroom (or door or box body or opening and closing Door etc.) sliding be deteriorated, lead to reliability reduce.

Additionally, it is 90% that the heat insulating box 700 of present embodiment 1 makes the filling rate of the Vacuumed insulation panel 400 in space 315 Below.Technological thought according to above-mentioned present embodiment is it is generally desirable to all Vacuumed insulation panels 400 in space 315.But It is, as illustrated by Figure 11 etc., in overleaf wall 730 is provided with protuberance 450 or jut 910, makes in addition to be formed at When the orbit portion 755 of case 750 is protrusively provided into space 315, in addition heat insulating box 700 is used for such as refrigerator 1, in wall Also to be configured in space 315 receive the pipe 720 of wire harness, therefore, it is difficult to making the filling rate of Vacuumed insulation panel 400 more than 90%, Above-mentioned wire harness is by connecting the compressor 12 carrying in the Machine Room 1A of heat insulating box 700, receive in control base board room 31 The distribution class boundling of control device 30 (for example controlling the device of rotating speed of compressor etc.) etc..Additionally, by hot box When body 700 is applied to such as refrigerator 1, refrigerant piping 725 also to be configured etc. in space 315.Therefore, in space 315 Inside configure Vacuumed insulation panel 400 more than 90% ground it is necessary to shape with distribution class 720, refrigerant piping 725, orbit portion 755 etc. The Vacuumed insulation panel 400 of shape coupling, the shape of Vacuumed insulation panel 400 becomes complicated, thus Vacuumed insulation panel 400 shaping (or Person is formed) become difficult, therefore the filling rate of Vacuumed insulation panel 400 is set as less than 90%.

Additionally, the problem deforming to suppress the intensity decreases of heat insulating box 700, need to make outer container 710 and interior Case 750 is bonding with Vacuumed insulation panel 400 and possesses adhesive strength, and is provided with for keeping located at storeroom (example in interior case 750 As refrigerating chamber 2) in the orbit portion 755 of shelf 80, other accessories (such as lighting device 900 or mist device 200 or separate Wall 24 etc.) situation more, complex-shaped.Therefore, even it is easy to for Vacuumed insulation panel 400 to pass through PUR or double faced adhesive tape etc. 2nd bonding agent bonds to outer container 710 side it is also difficult to make Vacuumed insulation panel 400 bond to complex-shaped interior case 750 side and obtain Adhesive strength.

But, using hard polyurethane foams as the bonding agent between interior case 750 and Vacuumed insulation panel 400 use when, can So that filling, foaming while it is flowed with two-phase state in space 315, even if therefore there is protuberance in space 315 450th, polyurethane can also be passed through without problems by interior case 750 and vacuum heat-insulation when jut 910, orbit portion 755, other accessories Part 400 is bonded together.It is of course also possible between outer container 710 and Vacuumed insulation panel 400 or outer container 710 and interior case 750 it Between filling hard polyurethane foams as bonding agent.Now, it is not filled by hard polyurethane foams if producing in heat insulating box 700 Be not filled by portion (i.e. space), then the heat-proof quality of heat insulating box 700 can reduce.Therefore, in the heat insulating box of present embodiment In 700 therefore, to assure that a certain degree of predetermined gap needed for filling hard polyurethane foams (e.g., from about more than 1mm, preferably About more than 3mm), therefore the filling rate of the Vacuumed insulation panel 400 in space 315 can be less than 90%, preferably less than 80%.

If however, making the filling rate of the Vacuumed insulation panel 400 in space 315 increase, the hard polyaminoester in space 315 The filling rate of foam will reduce.Therefore, the polyurethane between outer container 710 and interior case 750 thickness reduce, may result in every The casing intensity decreases of hot tank body 700.But, the heat insulating box 700 of present embodiment is by using heat-proof quality, bending rigidity All good than polyurethane Vacuumed insulation panel 400, can suppress the reduction of casing intensity.Additionally, in the present embodiment, technology is thought Think to be heat insulating function and intensity mainly to be undertaken by the little Vacuumed insulation panel of thermal conductivity 400, therefore as shown in figure 20, by making vacuum The filling rate of thermal insulation barriers is more than 40%, even if the loading of hard polyaminoester reduces it is also possible to improve the intensity of casing 700. Additionally, as shown in figure 19, by thickening the thickness (increasing the filling rate of Vacuumed insulation panel) of Vacuumed insulation panel 400, can contract The composite guide heating rate of the little compound heat-insulation part that Vacuumed insulation panel and hard polyurethane foams are combined, therefore casing 700 Heat-proof quality also improves.

If here, increasing the density of hard polyurethane foams increasing Deflection Modulus of Elasticity (bending rigidity), hard gathers The urethane foam heat-proof quality of itself can reduce, but by make the covering rate of Vacuumed insulation panel 400 and filling rate be predetermined value with On, the impact of the reduction of the heat-proof quality of polyurethane can diminish and not become problem.Heat insulating box 700 in present embodiment In, as shown in figure 16, by make hard polyurethane foams density ratio prior art big, be greater than 60kg/m³, can make The bending resistance bullet of the hard polyurethane foams by being used than existing heat insulating box for the Deflection Modulus of Elasticity of hard polyurethane foams Big more than the 15MPa of property modulus (e.g., from about 6～10MPa), can also improve the casing of the part not configuring Vacuumed insulation panel 400 Intensity.Therefore, the equipment such as the heat insulating box 700 of present embodiment, refrigerator 1, showcase, hot water supply device, by making vacuum heat-insulation The laterodorsal covering rate that the filling rate of part 400 is more than 40%, make Vacuumed insulation panel is more than 70%, can suppress because of hard The intensity decreases that the reduction of the filling rate of polyurethane foam leads to are additionally it is possible to suppression heat insulating box 700 is because tolerating storage item Lead to crooked of weight and deform.That is, by increasing the filling rate of Vacuumed insulation panel 400, heat insulating box 700 can be improved Intensity, furthermore, it is possible to obtain excellent heat-proof quality, therefore, it is possible to obtain that reliability is high and energy-conservation possess Vacuumed insulation panel Heat insulating box, possess Vacuumed insulation panel refrigerator, possess Vacuumed insulation panel showcase, possess Vacuumed insulation panel supplying hot water dress Put, possess equipment of Vacuumed insulation panel etc..

In addition, the density adjustment of hard polyurethane foams, for example can be by making the hard polyurethane being injected in space 315 The amount of the stoste of ester foam is filled and is obtained more than prior art (lengthen injection length or increase injection pressure) and and adjust density Larger or smallerly whole.Additionally, the Deflection Modulus of Elasticity of hard polyurethane foams is become substantially with the size of density as shown in figure 16 Ratio ground increases, and therefore increases density and just can increase Deflection Modulus of Elasticity, and when Deflection Modulus of Elasticity is larger, gear housing rigidity increases Greatly, therefore preferably, but the Deflection Modulus of Elasticity of polyurethane be preferably below 150MPa.The bending resistance springform of hard polyurethane foams If amount is more than 150MPa, the density of hard polyurethane foams becomes too much, can cannot be foamed into spongy and solidify, thermal insulation Can drastically reduce, therefore the Deflection Modulus of Elasticity of hard polyurethane foams is the fall that can suppress heat-proof quality during below 150MPa Low thus preferably, it is obtained in that high performance heat insulating box.

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

(1) the total thickness of slab using outer container 710 and interior case 750 is about below 2mm, includes the thickness of slab of outer container 710 and interior case The average wall thickness of the heat insulating box 700 of 750 thicknesss of slab is the heat insulating box of about more than 20mm about below 40mm (here, eliminating outer The average distance (thickness in wall) in the wall thickness direction in the space 315 of the thickness of slab of case 710 and interior case 750 is about 18mm～about 38mm).

(2) thickness of Vacuumed insulation panel 400 is about 10mm～about 30mm, and the part being configured with Vacuumed insulation panel is (for example recessed Portion 440 or second recesses 441) wall in space 315 in the wall thickness direction of hard polyurethane foams mean flowpath width (polyurethane stream thickness) is 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) internal volume be 200L～600L level, the consumption electric power under predetermined condition be about below 60W degree.

The heat-proof quality of this refrigerator 1 is passed through to be set to the filling rate making Vacuumed insulation panel 400 and covering rate be in predetermined In the range of and select the size of Vacuumed insulation panel 400, thickness, make the thermal insulation that Vacuumed insulation panel 400 is with respect to heat insulating box Can, the casing intensity of heat insulating box become overriding, thus when the thermal conductivity of Vacuumed insulation panel 400 is less, can reduce every The composite guide heating rate of hot tank body is thus preferably, preferably 0.0030W/ (m K) is below.If the thermal conductivity of Vacuumed insulation panel 400 surpasses Cross 0.0030W/m K, then the impact that wall thickness reduces to heat-proof quality becomes big, and heat-proof quality deteriorates, and power consumption increases.Cause This, in the present embodiment, by make Vacuumed insulation panel 400 thermal conductivity be 0.0030W/ (m K) below, can suppress with The impact that the relative heat-proof quality of thinning wall thickness reduces.Additionally, the thermal conductivity of Vacuumed insulation panel 400 is the smaller the better, but in order to incite somebody to action The cost that thermal conductivity reduces spent by 0.001W/ (m K) significantly increases, and therefore the thermal conductivity using Vacuumed insulation panel 400 is The part of more than 0.0012W/ (m K).If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (m K) above 0.0025W/ (m K) below, just little than the thermal conductivity of hard polyurethane foams about 10 times, the heat-proof quality of therefore heat insulating box 700 is compared Prior art is especially good, disclosure satisfy that product specification.Therefore, Vacuumed insulation panel 400 is about 0.0012W/ (m using thermal conductivity K) the part of above 0.0030W/ (m K) (the above 0.0025W/ of preferably from about 0.0019W/ (m K) (m K) is below) below ?.

As one of the heat insulating box 700 of embodiments of the present invention, wall thickness and Vacuumed insulation panel are shown in Table 1 400 filling rate, the Deflection Modulus of Elasticity of hard polyurethane foams, the relation of the box deformation amount of heat insulating box 700.Table 1 1 is existing specification, be wall thickness be 40mm, the filling rate of Vacuumed insulation panel 400 be 20%, in interior case 750 and vacuum heat-insulation Between part 400, the Deflection Modulus of Elasticity of the polyurethane of filling is result during 9MPa.Here, the bending resistance bullet of Vacuumed insulation panel 400 Property modulus use 20MPa part.Item 1 according to table 1 and item 2, the filling rate of Vacuumed insulation panel 400 is 20%, polyurethane When Deflection Modulus of Elasticity is 9MPa, if making the wall thickness of heat insulating box 700 be thinned to 30mm, casing intensity decreases from 40mm.Cause This, as shown in item 3 understand, make wall thickness reduction to 30mm in the case of, if making the filling rate of Vacuumed insulation panel 400 increase to More than 40%, although then box deformation amount is more slightly larger than item 1 (prior art), it is reduced to equal with item 1 (prior art) Degree.

As shown in the item 4 of table 1, even if the wall thickness of heat insulating box 700 is thinned to from existing 40mm (item 1 of table 1) 30mm, as long as making, the filling rate of Vacuumed insulation panel 400 is more than 40% and the Deflection Modulus of Elasticity of polyurethane is more than 15Mpa (item 4 of table 1) is so that it may so that box deformation amount is less than prior art (item 1), therefore can make the casing of heat insulating box 700 strong Spend more than for existing part (item 1).That is, even if reducing wall thickness (being for example reduced to 30mm from 40mm), as long as by Vacuumed insulation panel 400 filling rate and the Deflection Modulus of Elasticity of polyurethane are set as more than predetermined value it is possible to not improve with not reducing casing intensity Heat-proof quality.Therefore, in the present embodiment, by using more than Deflection Modulus of Elasticity 20MPa as Vacuumed insulation panel 400 Part, 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 It is set to more than 15MPa, even if the wall thickness (being for example thinned to 30mm from 40mm) of thinning heat insulating box is it is also possible to compared to existing technology Improve the intensity of heat insulating box 700.

In addition, the Deflection Modulus of Elasticity of hard polyurethane foams in present embodiment 1, thermal conductivity, the mensure of density, example As measured by cutting the hard polyurethane foams of predefined size (such as 100 × 100 × more than 5mm).It is being configured with The part of Vacuumed insulation panel 400, is configured with Vacuumed insulation panel from each face in left and right side, the back side, top surface, this five faces of bottom surface Partly cut multiple, calculate its mean value.(when only cutting 1 position, carry out many places mensure etc. at 1 position next alternative It is advisable).When door is also configured with Vacuumed insulation panel, opposite house also measures the density of polyurethane, Deflection Modulus of Elasticity, thermal conductivity are Can.Additionally, in the part not configuring Vacuumed insulation panel 400, also to left and right side, the back side, top surface, this five faces of bottom surface each face Cut multiple, and calculate its mean value.In the present embodiment, be all in any case from can speculate density or The larger place of Deflection Modulus of Elasticity is cut and is measured.In addition, joining in the distribution that there is refrigerant piping 725, lead etc. In the case of hard polyurethane foams can not being cut into predefined size during part 720 grade etc., using close to center position as The position that the hard polyurethane foams of predefined size can be cut is advisable.

In the present embodiment, each face to this six faces of left surface, right flank, the back side, top surface, bottom surface or door, The density of polyurethane of the mensure part being configured with Vacuumed insulation panel 400 and the part not configured or Deflection Modulus of Elasticity, make The density of polyurethane or Deflection Modulus of Elasticity are more than predetermined value.Can be by adjusting the free foaming density of polyurethane, true The thickness of empty thermal insulation barriers, wall thickness etc., will be between Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container The density of the polyurethane of sandwiched or Deflection Modulus of Elasticity are set as making a reservation between 710 or between outer container 710 and interior case 750 More than value.

Here, in the present embodiment, in this six faces of left and right side, the back side, top surface, bottom surface or door, for each face It is configured with the density of the polyurethane of the part of Vacuumed insulation panel 400 to major general, Deflection Modulus of Elasticity is set as more than predetermined value, this Each face to major general can also not configured to the density of the polyurethane of part of Vacuumed insulation panel 400 outward, Deflection Modulus of Elasticity sets It is set to more than predetermined value.Here, in this six faces of left and right side, the back side, top surface, bottom surface or door, if being set to for each face Make polyurethane density, Deflection Modulus of Elasticity be more than predetermined value, then also carry in the partial intensities not configuring Vacuumed insulation panel 400 High.Further, since being obtained in that intensity in each single face, therefore only the section sets of needs can be become high intensity, energy Enough acquisition low costs and the high heat insulating box of reliability, refrigerator, equipment.Make left and right side, the back side, top surface, bottom additionally, being set to The mean value of the density in face or this six faces of door or Deflection Modulus of Elasticity is more than predetermined value (density 60kg/m³Above, anti- Curved more than elastic modelling quantity 15MPa) when it can be ensured that the intensity of whole casing, therefore, it is possible to obtain, heat-proof quality is high, reliability is high Heat insulating box, refrigerator, equipment.

Additionally, for the covering rate of Vacuumed insulation panel 400, filling rate, also left and right side, the back side, top surface, bottom surface or This six faces of door are set to makes each face or multiple face covering rate altogether, filling rate be more than predetermined value, due at each Individually face is obtained in that intensity, heat-proof quality, therefore only the section sets of needs can be become high intensity, be obtained in that low one-tenth Basis, the heat insulating box that height is heat-insulated, reliability is high, refrigerator, equipment.Additionally, be set to make left and right side, the back side, top surface, bottom surface or It can be ensured that the intensity of whole casing, the heat-proof quality of whole casing of improving when more than this six faces generally predetermined value of person's door, Therefore, it is possible to obtain the heat insulating box that heat-proof quality is high, reliability is high, refrigerator, equipment.

More than, in the heat insulating box 700 of present embodiment, make the covering rate of Vacuumed insulation panel 400 be more than predetermined value (60%) (the laterodorsal covering rate making Vacuumed insulation panel 400 is more than 70%).Additionally, making the filling of Vacuumed insulation panel 400 Rate also be predetermined value (40%) more than with reduce hard polyurethane foams loading, therefore, it is possible to guarantee the heat-insulated of heat insulating box Performance and casing intensity, can make simultaneously heat insulating box 700 wall ratio prior art thin.Therefore, heat-proof quality is carried High thus energy-conservation, and the indoor internal volume of storage can be made compared to existing technology to increase the amount of wall thickness reduction such that it is able to carry For the heat insulating box 700 of internal volume good efficiency, refrigerator 1, showcase, equipment.I.e., according to the embodiment of the present invention, constant The appearance and size of the more equipment such as heat insulating box 700 or refrigerator 1 or showcase can increase internal volume (example compared to existing technology Internal volume as storeroom 2～6), therefore comparable prior art increases heat insulating box 700 or the inside of refrigerator 1 can be stored Storage item.Thereby, it is possible to obtain the equipment such as user's convenient use, the heat insulating box 700 of energy-conservation, refrigerator 1, showcase.Conversely, If making internal volume (internal volume of such as storeroom 2～6) equal with prior art, appearance and size can be reduced, therefore, it is possible to obtain The equipment such as energy-conservation and compact heat insulating box 700, refrigerator 1, showcase, hot-water supply of obtaining.

In addition, the heat insulating box 700 shown in present embodiment, the mode of refrigerator 1, shape only.For example, The reserve accommodation space of heat insulating box 700 can be formed four storages with 3 cross septation plate zonings in above-below direction empty Between (storeroom).Additionally, for example the reserve accommodation space of heat insulating box 700 can also be gone forward side by side with 3 cross septation plate zonings The vertical demarcation strip zoning of one step, thus form five accommodation spaces (storeroom).By increasing the quantity of demarcation strip 24, Ke Yijin One step improves the intensity of heat insulating box 700.That is, more it is to increase the quantity of demarcation strip 24 quantity to increase receiving room, storeroom, The effect improving casing intensity by demarcation strip can be obtained, even if thus the thinning portion being covered by Vacuumed insulation panel 400 Point hard polyurethane foams (space 315 between Vacuumed insulation panel 400 and interior case 750) average thickness (such as 11mm with Under, preferably smaller than 10mm, more preferably below 6mm) it is also possible to guarantee enough casing intensity.Therefore, do not change heat insulating box 700 appearance and size just can increase the internal volume of storeroom further, and the inside that can increase heat insulating box 700 further can The storage item of storage.

Additionally, in the present embodiment, with regard to the internal structure of demarcation strip 24, can be same with heat insulating box 700 Constitute.That is, configure Vacuumed insulation panel 400 in the inner space of demarcation strip 24 and fill hard polyurethane foams, but hard polyurethane As long as ester foam is used as bonding agent, therefore can be relatively thin, for example can be about below 11mm, be preferably smaller than 10mm, more excellent Elect about below 6mm as.Here, in the feelings not configuring pipe arrangement 725, distribution 720 etc. in demarcation strip 24 as heat insulating box 700 Condition is more, therefore in this case although can also be set as Vacuumed insulation panel 400 with respect to the filling rate of demarcation strip 24 Less than more than 40% 90% equal with heat insulating box 700, but with regard to partition wall 24, (can separate in the size of demarcation strip 24 Space in plate 24) substantially entire surface configuration Vacuumed insulation panel 400, therefore the filling rate of Vacuumed insulation panel 400 can be carried Height arrives less than about more than 40% 95%.Additionally, the Deflection Modulus of Elasticity of hard polyurethane foams is more than 15MPa, density being more than 60kg/m³It is advisable.By so also configuring Vacuumed insulation panel 400 in demarcation strip 24 and filling rate being set in preset range, The heat-proof quality of heat insulating box 700 can be improved further.

In the present embodiment, it is considered to assemble in the case of the heat insulating box possessing Vacuumed insulation panel or thermal wall Property and Vacuumed insulation panel 400 is adhered directly onto by the 2nd bonding agent different from polyurathamc such as PUR or double faced adhesive tape Outer container 710, as the bonding agent filling hard polyurethane with bonding as main purpose between Vacuumed insulation panel 400 and interior case 750 Ester foam but it is also possible in the space 315 being formed between outer container 710 and interior case 750 configuration by the resins such as EPS formed every Vacuumed insulation panel 400 is floated between interior case 750 and outer container 710 and configured from thing etc., and in Vacuumed insulation panel 400 with outward Hard polyurethane foams are filled between case 710 and between Vacuumed insulation panel 400 and interior case 750.In addition it is also possible to by vacuum every Warmware 400 is adhered directly onto interior case 750 and in Vacuumed insulation panel 400 and outer container by PUR or double faced adhesive tape etc. the 2nd bonding agent Filled polyurethane foam between 710.

Here, make Vacuumed insulation panel 400 pass through spacer etc. float over configured between outer container 710 and interior case 750 when, Can be in inner face side (space between outer container 710 and Vacuumed insulation panel 400) the setting spacer of outer container 710 and empty in spacer Between setting refrigerant piping 725 (for example condensing pipe arrangement).Refrigerant piping 725 is also the compression making from being configured in the 1A of Machine Room The condensation pipe arrangement of the cold-producing medium flowing of the HTHP that machine 12 is discharged, tube wall and outer container 710 via refrigerant piping 725 are being led In the presence of heat etc., the cold-producing medium of flowing in pipe arrangement 725 is made to be cooled down by the air around pipe arrangement 725 and make cold-producing medium cold Solidifying, thus using as condensation pipe arrangement.Additionally, the heat insulating box 700 of present embodiment is nonoverlapping with refrigerant piping 725 The inwall setting of the outer container 710 of position (not opposite position) has the resin of the thickness of more than the diameter of refrigerant piping 725 The spacer of system, and make Vacuumed insulation panel 400 paste spacer, so, make refrigerant piping 725 against outer container 710 After ground configuration, can by by be pasted with the spacer of Vacuumed insulation panel 400 to cover refrigerant piping 725 in the way of directly with two-sided Glue etc. pastes outer container 710 it is easy to manufacture.Vacuumed insulation panel 400 is configured to and interior case by the heat insulating box 700 of present embodiment 750 at predetermined spaced intervals, and Vacuumed insulation panel 400 is configured to outer container 710 at predetermined spaced intervals, therefore become vacuum Thermal insulation barriers 400 are embedded in the composition in hard polyurethane foams, and heat-proof quality is improved.

As described above, in the present embodiment, heat insulating box 700 can space between outer container 710 and interior case 750 In 315 foam filled so that Vacuumed insulation panel 400 is embedded in hard polyurethane foams, should in the case of in outer container 710 and vacuum The situation that there is condensation pipe arrangement 725 between thermal insulation barriers 400 is more, but can be by being configured to using the resinous isolation such as EPS Thing etc. makes Vacuumed insulation panel 400 and outer container 710 have predetermined distance, to configure Vacuumed insulation panel 400.

Additionally, Vacuumed insulation panel 400 is when becoming high temperature, easily absorb the gas of surrounding, the vacuum of inside can be led to Reduce, thermal conductivity deteriorates.In the case of the outside air temperatures such as summer height, the environment temperature (air themperature of surrounding) of outer container 710 Uprise, outer container 710 temperature of itself is likely to uprise, additionally, the pipe arrangement 725 using as condensation pipe arrangement also becomes high temperature, because This preferably makes Vacuumed insulation panel 400 away from outer container 710, refrigerant piping from the angle of the reliability guaranteeing Vacuumed insulation panel 400 (condensation pipe arrangement) 725.By making Vacuumed insulation panel 400 away from outer container 710, refrigerant piping (condensation pipe arrangement) 725, can suppress The deterioration that Vacuumed insulation panel 400 causes because temperature rises, if therefore make Vacuumed insulation panel 400 pass through spacer etc. float with remote From outer container 710 wall or refrigerant piping 725 it is possible to suppression heat-proof quality reduction, reliability can be provided for a long term High heat insulating box 700, refrigerator 1.

Additionally, Vacuumed insulation panel 400 sometimes because absorb around gas (air etc.) and lead to inside vacuum decline, Thermal conductivity deteriorates, but by being configured to for resinous for EPS etc. spacer to paste the ground such as outer container 710 in hard polyurethane foams Interior embedded Vacuumed insulation panel 400, it is possible to reduce the amount of the gas (air etc.) of the surrounding of Vacuumed insulation panel 400, therefore may be used To suppress Vacuumed insulation panel 400 to absorb the gas (air etc.) of surrounding, the vacuum leading to because of the reduction of vacuum can be suppressed The deterioration of thermal insulation barriers 400, can maintain high heat-proof quality for a long time, and can provide the high heat insulating box of reliability 700, refrigerator 1st, equipment etc..

Especially, in the heat insulating box 700 of present embodiment, hard polyurethane foams use density ratio existing heat-insulated Hard polyurethane foams that casing is used high (density is more than 60kg/m³), the therefore bubble in hard polyurethane foams The amount that density increases can correspondingly be reduced, it is possible to reduce the amount (air capacity) of the gas in bubble.Therefore, so that Vacuumed insulation panel When 400 surrounding is buried by hard polyurethane foams or the mode that covers is filled with or configures, it is possible to reduce vacuum every The amount of the gas (air etc.) of the surrounding of warmware 400, therefore can suppress the reduction of the vacuum of Vacuumed insulation panel 400 (density of polyurethane is bigger, and the space number in polyurethane is fewer, and the air capacity in polyurethane is fewer).Especially in polyurethane During thinner thickness (during for example, below 11mm), Vacuumed insulation panel 400 easily makes the gas such as air of grade around polyurethane Enter, therefore increase polyurethane density come to reduce Vacuumed insulation panel 400 surrounding gas flow for Vacuumed insulation panel 400 The effect of degradation inhibiting is larger.Therefore, it can suppress the deterioration of Vacuumed insulation panel 400 further, reliability can be provided for a long term High heat insulating box 700, refrigerator 1, equipment.

In addition, entering in the present embodiment taking the heat insulating box 700 that condensation pipe arrangement 725 is configured in space 315 as a example Go explanation, but can certainly be in hard in the heat insulating box 700 condensation pipe arrangement 725 not being configured in space 315 Vacuumed insulation panel 400 is buried in polyurethane foam.The amount of the gas of the surrounding of Vacuumed insulation panel 400 can be reduced, therefore The deterioration of Vacuumed insulation panel 400 can be suppressed, the high heat insulating box of reliability 700 can be provided for a long term.

Here, not forming orbit portion (track of the drawer of drawer type storeroom or recess etc.) 755 in interior case 750 The heat insulating box 700 of composition, situation of refrigerator 1 etc., interior case 750 are to be easy to directly paste vacuum using bonding agent or double faced adhesive tape etc. It is also possible to all or part of by Vacuumed insulation panel 400 is configured at interior case 750 side during the shape of thermal insulation barriers 400.

Here, as shown in the embodiment Vacuumed insulation panel 400 is being adhered directly onto by PUR or double faced adhesive tape etc. In the case of the heat insulating box 700 of composition of interior case 750 side, energy-conservation and storage can be provided with lesser amount of Vacuumed insulation panel 400 Hide the internal volume efficiency of the room heat insulating box 700 better than prior art, refrigerator 1.That is, in approximately parallelepiped body shape or cylindrical shape In the case of heat insulating box 700, in the surface area ratio of outer container 710, the surface area of case 750 is big, is therefore pasting Vacuumed insulation panel When 400, the Vacuumed insulation panel 400 being bonded at interior case 750 surface is fewer than the Vacuumed insulation panel 400 being bonded at outer container 710 surface, therefore can Enough acquisition low costs and the good heat insulating box of heat-proof quality, refrigerator, showcase, hot water supply device, equipment.Additionally, for example pasting During the Vacuumed insulation panel 400 of formed objects, in the corner of rectangular-shaped heat insulating box 700 (for example as heat insulating box 700 The corner at the corner of the corner of the connecting portion of the back side and side or top surface and side or top surface and the back side etc.), corner portion Gap between the Vacuumed insulation panel 400 of wall adjacent one another are (Vacuumed insulation panel 400 of such as top surface and adjacent side true Gap between empty thermal insulation barriers 400 or distance), when Vacuumed insulation panel 400 is configured at outer container 710 side, than by vacuum every Warmware 400 is configured at big during interior case 750 side.That is, by Vacuumed insulation panel 400 is configured at interior case 750, and by formed objects Vacuumed insulation panel 400 is configured to be compared during outer container 710, can reduce being formed each other in adjacent Vacuumed insulation panel 400 Gap, makes the heat waste leading to because of heat leak correspondingly reduce the amount of gap shrinks, using the teaching of the invention it is possible to provide the good heat insulating box of heat-insulating efficiency 700th, refrigerator 1, hot water supply device, showcase, equipment.

Additionally, the heat insulating box 700 of present embodiment is possessed for internally being formed using zonings such as partition walls 24 The radial type that is opened and closed of opening portion of multiple storerooms 2,3,4,5,6 or the shutter door of drawer type.This door possesses by example The profile parts (outside plate) constituting as metal and the inner part (inner panel) being made up of such as resin.And, it is being formed at profile In door inner space between part and inner part, configuration (filling) has hard polyurethane foams and Vacuumed insulation panel 400.Door It is also based on the following technological thought illustrated by present embodiment and formed：By Vacuumed insulation panel filling out with respect to heat insulating box The rate of filling is set in preset range and is had the overwhelming majority of heat insulating function by Vacuumed insulation panel 400.Make the vacuum of an inner space The filling rate of thermal insulation barriers 400 is 40%～90%, covering rate is more than 70%.

When manufacturing this shutter door, by Vacuumed insulation panel 400 beforehand through profile portion that is adhesively fixed such as the 2nd bonding agents Part, by the space between the raw material injection Vacuumed insulation panel of liquid hard polyurethane foams and inner part, outer part Space and inner part between, to enable profile parts, Vacuumed insulation panel 400, the integral part of mode of inner part to enter Row foaming, such that it is able to fill the hard polyurethane foams as foaming heat insulation part in door inner space.Now, hard polyurethane As long as the thickness of ester foam is also the intensity having as bonding agent, can be more than 1mm preferably more than 3mm and 11mm Below (preferably smaller than 10mm, more preferably below 6mm).

In addition, for shutter door, existing and install for supporting containing box (storage box body 520) in storeroom 2,3,4,5,6 Framework or door storage portion or shelf 80 etc. situation, thus exist needing the fixing screws of framework, door storage portion Fixed component, installing component of shelf 80 etc. using the secure components such as screw, fixed component, holding member and fasten or keep Situation to the inner side (inside case) of shutter door.In this case, there is secure component, fixed component, holding member into door The situation that portion space projects, if contact with Vacuumed insulation panel 400 it is possible to the outsourcing material of Vacuumed insulation panel can be damaged, therefore Preferably configured or filled polyurethane foam with the thickness that will not damage Vacuumed insulation panel 400 in the inner side of shutter door.However, simultaneously Especially do not need to be installed on installation fitting (such as secure component, fixed component, the guarantor of (inboard side) inside the storeroom of shutter door Hold part etc.) when it is also possible to Vacuumed insulation panel 400 is pasted inner panel.In addition, avoiding installation fitting setting Vacuumed insulation panel When it is also possible to Vacuumed insulation panel is pasted inner panel.

Additionally, there is profile parts (outside plate) and inner part (inner panel), being formed at profile parts and inner part Between door inner space configuration Vacuumed insulation panel 400, fill out between profile parts or inner part and Vacuumed insulation panel 400 In the case of useing the hard polyurethane foams for foaming heat insulation part as, if making the density of foaming heat insulation part be more than 60kg/m³, then right The fixed component being fixed for the framework supporting containing box (storage box body 520) is the holding intensity of screw etc. or fixing strong Degree is improved, even if therefore receiving weight in box body 520, door is also difficult to deform, and can stably carry out going out of box body 520 Enter, be obtained in that the high refrigerator of reliability, equipment.Additionally, the fixed component for miscellaneous parts such as fixed handles is screw etc. Holding intensity or fixing intensity be improved, therefore the door installing component such as handle as miscellaneous part is being installed on door When, door installing component is improved to the installation strength of door, and therefore door is difficult to deform, and can stably carry out the opening and closing of door, energy Enough obtain the high refrigerator of reliability, equipment.If additionally, making between profile parts or inner part and Vacuumed insulation panel 400 Hard polyurethane foams as foaming heat insulation part are more than 60kg/m³, then the Deflection Modulus of Elasticity of foaming heat insulation part be improved, The intensity of door is also improved.

Here, Vacuumed insulation panel 400 can be configured at all of shutter door or a part of shutter door.For example, in outer gas and When the temperature difference of (for example storing indoor) in heat insulating box 700 is smaller (the such as refrigerated storage temperature band such as refrigerating chamber 2, vegetable compartment 5 Storeroom), even if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality is improved is also less.In this case, Even if Vacuumed insulation panel 400 is not configured to the heat-proof quality that shutter door can also ensure that abundance.Vacuumed insulation panel 400 is in outer gas With the temperature difference (for example storing indoor) in heat insulating box 700 than larger when (for example ice-making compartment 3, switch room 4, refrigerating chamber 6 etc. are cold Freeze the storeroom of temperature band), if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality is improved is larger.Cause This, the feelings of the storeroom than larger cryogenic temperature band for the temperature difference (for example storing indoor) in outer gas and heat insulating box 700 Under condition, by Vacuumed insulation panel 400 being configured at shutter door it can be ensured that the heat-proof quality of abundance.

More than, in the heat insulating box 700 or refrigerator 1 or equipment of present embodiment, with respect to will be in outer container 710 He The space 315 being formed between interior case 750 and the inner space Ji Men inner space spatial volume altogether of shutter door, vacuum every Volume ratio shared by warmware 400 is the filling rate within a predetermined range (such as more than 40% 80% of Vacuumed insulation panel 400 Below).Therefore, it can to make heat insulating box 700 wall thickness (such as the distance between outer container 710 and interior case 750 and shutter door Thickness) thinner than prior art, therefore, it is possible to providing energy-conservation and storing the heat insulating box 700 of indoor internal volume excellent in efficiency, refrigerator 1st, equipment.Therefore, even if not changing the appearance and size of heat insulating box 700 or refrigerator 1 it is also possible to make the indoor internal volume of storage Bigger than existing, therefore can increase the storage item that the inside of heat insulating box 700 can be received compared to existing technology.Therefore, may be used To provide than prior art energy-conservation and heat-proof quality is good, commodity value is high heat insulating box 700, refrigerator 1, hot water supply device, display Cabinet, equipment.

In addition, by the filling rate increasing the Vacuumed insulation panel 400 in space 315, the rigid polyurethane foam in space 315 The filling rate of foam reduces.In the heat insulating box 700 of present embodiment, make the density ratio prior art of hard polyurethane foams big (it is greater than 60kg/m³), the Deflection Modulus of Elasticity making hard polyurethane foams is harder than what existing heat insulating box was used Big more than the 15.0MPa of the Deflection Modulus of Elasticity (about 6MPa～10MPa) of matter polyurethane foam.Therefore, present embodiment every Hot tank body 700 can also suppress the intensity decreases that the reduction of the filling rate because of hard polyurethane foams causes, and there is not hot box Body 700 becomes because of cause crooked of the weight of reserve accommodation space or the indoor storage item of storage or shutter door because tolerating The problems such as shape, it is obtained in that the high heat insulating box of reliability 700, refrigerator 1, equipment.

Therefore, in the refrigerator 1 of present embodiment or possess the equipment of the heat insulating box 700 with Vacuumed insulation panel 400, Heat insulating box 700 can be suppressed crooked and make shutter door tilt etc. shutter door cannot smooth opening and closing situation, furthermore, it is possible to suppression Deterioration because of the outward appearance that deformation causes.Furthermore, it is possible to prevent shutter door and the sealing gasket for sealing the opening portion of heat insulating box The position relationship of contact surface (sealing surface) deviate and produce gap so that the indoor air of storage (is cold in the case of refrigerator Gas) to outside heat insulating box flow out situation.Thus, even if heat insulating box 700 can also be suppressed using Vacuumed insulation panel 400 in a large number Performance reduce, reliability reduce, there is excellent heat-proof quality, therefore can with obtain energy-conservation and the high refrigerator of reliability or The heat insulating box with Vacuumed insulation panel or the equipment possessing Vacuumed insulation panel, possesses the equipment of heat insulating box.

Here, heat insulating box 700 when for refrigerator for above-below direction height over width direction length big During elongated rectangular shape, compare partition wall 24 between the bottom surface sections 780 of approximate horizontal configuration, top 740, storeroom etc., The side wall 790 that substantially vertically configures, back face wall 730 are in elongated shape, and therefore rigidity is weak and be easily deformed.Therefore, pass through As in this embodiment the filling rate of Vacuumed insulation panel 400, covering rate are set within a predetermined range, hot box can be improved The intensity (rigid) of body 700.Additionally, casing intensity can also be improved by arranging protuberance 450 or jut 910.Additionally, setting It is set to the one end making protuberance 450 and the Vacuumed insulation panel 400 being configured at recess 440 or second recesses 441 is weighed with predetermined length X 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 and protuberance 450 are integrally formed, furthermore, it is possible to make Vacuumed insulation panel 400 be integrally formed with side wall 790 via hard polyurethane foams, therefore The intensity of casing 700 can be improved.

Figure 21 is the surface area institute representing the side surface part 790 that Vacuumed insulation panel 400 is with respect to heat insulating box 700 and back part The figure of the relation of the area ratio (side back side covering rate) accounting for and box deformation amount, is result of calculation.Strong with regard to heat insulating box Degree, side wall 790, back face wall 730 be shaped as elongated oblong-shaped, with top wall 740, underside wall 780, partition wall 24 etc. Substantially square shape compare rigidity weaker, therefore by by the side back side covering rate of Vacuumed insulation panel 400 be set as predetermined value with On, casing intensity can be improved.Here, to Vacuumed insulation panel 400 with respect to shared by the surface area of side wall 790 and back face wall 730 Area ratio (side back side covering rate) illustrate with the relation of casing intensity.

In figure 21, transverse axis represents Vacuumed insulation panel 400 with respect to the side wall 790 of heat insulating box 700 and back face wall 730 Area ratio (side back side covering rate) shared by surface area, the longitudinal axis represents the deflection of casing.Here, set the density of polyurethane as 60kg/m³, Vacuumed insulation panel 400 filling rate be 40%, laterodorsal area ratio (side back side covering rate) be when 50% Box deformation amount is 1.The Deflection Modulus of Elasticity calculating used Vacuumed insulation panel 400 is 20MPa, based on actually used true The measurement result of the Deflection Modulus of Elasticity of empty thermal insulation barriers, using the Deflection Modulus of Elasticity than existing hard polyurethane foams (about 6MPa～10MPa) big part.Here, when changing area ratio (side back side covering rate), the filling rate of Vacuumed insulation panel is solid It is set to 40%, if the area ratio (side back side covering rate) of therefore Vacuumed insulation panel increases, the thickness of Vacuumed insulation panel diminishes.

In addition, the refrigerator 1 for calculating is one it is assumed that more than 4 (such as 4 or 5 or 6 specifications), interior Volume is 500L level, consumption electric power is about the refrigerator of below 40W.Distance including the plate thickness between outer container 710 and interior case 750 (wall thickness) average out to 30mm is it is assumed that the thickness of slab of outer container 710, interior case 750 is respectively 1mm, thus the thickness in space 315 is (thick in wall Degree) it is 28mm.The density of hard polyurethane foams is 60kg/m³, Vacuumed insulation panel 400 thermal conductivity be 0.0021 (W/m K), the thermal conductivity of hard polyurethane foams be 0.019 (W/m K), Vacuumed insulation panel 400 compared with hard polyurethane foams every Good in thermal property about 10 times about.

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

Understand in figure 21, the area ratio of Vacuumed insulation panel 400 is bigger, and box deformation amount is less.Make side/back side When area ratio (laterodorsal Vacuumed insulation panel covering rate) is more than 70%, the rate of change of box deformation amount diminishes.That is, to side Till the area ratio at face/back side is 70% about, if area ratio becomes big, box deformation amount drastically diminishes, but when side/ When the area ratio at the back side becomes more than 70%, even if area ratio becomes big, box deformation amount hardly changes.Therefore, When the area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side is more than 70%, the reduction of the deflection of casing Ratio is minimum, even if the side backside area ratio of Vacuumed insulation panel increases, box deformation amount also hardly changes.This is recognized For be due to, Vacuumed insulation panel laterodorsal area ratio for casing intensity influence degree substantially close to saturation.

Here, making the filling rate of Vacuumed insulation panel be fixed as 40% to calculate, if therefore increasing joining of Vacuumed insulation panel 400 Put area, then the lower thickness of Vacuumed insulation panel 400.Area ratio to the side/back side of Vacuumed insulation panel is 70% about Till, if increasing the area ratio at side/back side, with the lower thickness of Vacuumed insulation panel and the increase of box deformation that causes Amount is compared, because the intensity that the configuration area of Vacuumed insulation panel becomes the casing causing greatly improves the decrement of led to box deformation Bigger, the rigidity of therefore casing improves, the deflection of casing reduces.But, the area ratio at the side/back side of Vacuumed insulation panel When exceeding about 70%, the increase of the box deformation that the intensity decreases of the casing causing because of the lower thickness of Vacuumed insulation panel are led to The intensity of casing that amount and the configuration area change because of Vacuumed insulation panel cause greatly improve the decrement of led to box deformation into Same degree, the minimizing degree of the deflection of casing diminishes.

Additionally, making the lower thickness of Vacuumed insulation panel by increasing the configuration area ratio (covering rate) of Vacuumed insulation panel When, the thickness of polyurethane foam is thickening.To configuration area ratio is 70% about, the thickness of Vacuumed insulation panel is predetermined thickness More than degree, therefore compare the decrement of the thickness of Vacuumed insulation panel, the shadow of the incrementss of the area ratio intensity to heat insulating box Ring bigger, box deformation amount reduces, if but increasing the configuration area ratio of Vacuumed insulation panel, the thickness of Vacuumed insulation panel further Degree diminishes, and the thickness of polyurethane becomes big, thus the configuration area ratio of the incrementss of the thickness of polyurethane and Vacuumed insulation panel The impact of the intensity to heat insulating box for the incrementss becomes equal, and the minimizing degree of box deformation amount diminishes.

Therefore, if the area ratio (side back side covering rate) at the side/back side of Vacuumed insulation panel 400 is set as predetermined value (70%) it is possible to obtain casing intensity, the casing high therefore, it is possible to obtain reliability more than.If additionally, by Vacuumed insulation panel The area ratio at side/back side be set as more than predetermined value (70%), then become what box deformation amount hardly changed Region, even if the configuration area of therefore Vacuumed insulation panel produces inequality, the deflection of casing also hardly changes, and therefore can Enough obtain high intensity, aesthetic appearance is good, reliability is high heat insulating box, refrigerator, showcase, equipment.If making Vacuumed insulation panel 400 Covering rate is more than predetermined value (more than 60%) and the area ratio at the side/back side of Vacuumed insulation panel 400 is set as the 2nd More than predetermined value (70%), then heat-proof quality improves, and can reduce box deformation amount, therefore, it is possible to obtain heat-proof quality Greatly, reliability height and the refrigerator of energy-conservation, showcase, equipment.

If here, making the thickness of Vacuumed insulation panel fix and expand the configuration area of Vacuumed insulation panel 400, vacuum heat-insulation The covering rate of part, filling rate all can increase, if but the increase of the filling rate of Vacuumed insulation panel 400, cost increase, therefore do not change Become filling rate and by increase covering rate improve heat insulating box 700 intensity when cost relatively low, and can increase vacuum every The configuration area of warmware, therefore heat-insulating efficiency improves.Therefore, it is more than 40%, makes by making the filling rate of Vacuumed insulation panel 400 The area ratio (laterodorsal Vacuumed insulation panel covering rate) at side/back side is more than 70%, can with low-cost high-efficiency ground really Protect the intensity of heat insulating box.Therefore, if area ratio (the laterodorsal Vacuumed insulation panel by the side/back side of Vacuumed insulation panel Covering rate) be set as the 2nd predetermined value (be the reduction ratio of the deflection of heat insulating box diminish area ratio, for example, 70% Left and right) more than it is possible to the wall thickness (thickness of thinning polyurethane) of thinning heat insulating box 700, increase storeroom internal volume.Side The configuration area (laterodorsal Vacuumed insulation panel covering rate) of the Vacuumed insulation panel 400 of wall 790 and back face wall 730 is bigger, heat-insulated The deflection of casing 700 is less, therefore can increase the intensity of heat insulating box 700 it is provided that high intensity and heat-proof quality is good Heat insulating box 700, refrigerator 1, possess the equipment of heat insulating box.

(polyurethane physical property)

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

Here, free foaming density refers to, not in the airtight space such as casing, make polyurethane foam but opening Container in etc. make the density of hard polyurethane foams during polyurethane foam under open mode.And in fact, due to polyurethane Foaming, expansion in the airtight narrow space in heat insulating box 700, therefore in the narrow space that heat insulating box 700 etc. is airtight Interior foaming, the density of the polyurethane expanding are bigger than the free foaming density of foaming in the open state, the polyurethane of expansion.

By improving the density of the hard polyurethane foams after foaming, as illustrated in figure 16, bending resistance springform can be increased Amount, but when making polyurethane stock solution flow directly into heat insulating box 700 and be filled with increasing density, for the foaming currently using The little polyurethane of multiplying power, free foaming density little to 26～28kg/m³, expansion ratio is little, if the part of therefore polyurethane flowing Stream thickness have that size is not, then foaming degree is uneven, near inlet 703,704 and terminal part is (away from inlet Position) polyurethane density easily produces inequality it is difficult to obtain stable intensity.

In the present embodiment, by using free foaming density than existing (e.g., from about 25～28kg/m³) big hard (such as free foaming density is about 30～45kg/m to polyurethane foam³), even if the stream thickness of the part in polyurethane flowing There is a little size not, also due to expansion ratio can stably foam greatly, the inequality of the density after foaming can be reduced. Thus, it is easy to make the polyurethane after foaming density generally uniform.

The such foaming body of hard polyurethane foams, internally has bubble, and density is less, and bubble is more, heat-insulated effect Fruit is higher.Therefore, in prior art, heat insulating box 700 makes the density after the foaming of the hard polyurethane foams being used be About 25～28kg/m³Little density hard polyurethane foams.Want to make bending resistance springform using this existing polyurethane foam Measure for more than 15MPa with guarantee heat insulating box 700 intensity when, such as in the case that in wall, thickness is 28mm, true removing The thickness of the polyurethane after the thickness of empty thermal insulation barriers be 8mm heat insulating box in it is necessary to injection, just the filling out of packing ratio polyurethane Charge (is will not to apply irrational load etc. into the casing become object and just fill poly- during hard polyurethane foams Urethane amount, the density after foaming easily becomes uniform) how polyurethane, density easily produces inequality.

And then, the polyurethane due to injecting, more than the lucky loading of packing ratio is it is therefore desirable to add when polyurethane injects Pressure or prolongation filling time, thus polyurethane is from the gap such as heat insulating box 700, junction surface of the profile of shutter door (such as outer container 710 and the junction surface of interior case 750) spill it is impossible to inject the scheduled volume needed for (cannot fill) polyurethane it is difficult to guarantee fill The density of the hard polyurethane foams to after casing is than predetermined value (such as 60kg/mm³) big density.If additionally, polyurethane Spill from the profile of casing it is necessary to remove the operation of the polyurethane spilling, activity duration or built-up time need to increase, and lead Cost is caused to raise, aesthetic appearance reduces.Therefore, the density being filled into the polyurethane after heat insulating box in prior art is less than 60kg/ m³, about 25～30kg/m³, up to about 55kg/m³Below.

Here, in the present embodiment, have studied by the amount reducing the expanded material comprising in polyurethane stock solution etc. Lai Increase free foaming density.The such as thickness in polyurethane is that (the polyurethane stream after removing the thickness of Vacuumed insulation panel is thick for 8mm Degree is about 8mm) heat insulating box 700 in, by free foaming density is set as predetermined value (30kg/m³Above, preferably 35kg/m³More than), can make the density under lucky loading (do not apply the ground such as irrational load be filled into poly- after casing The density of urethane) compare 60kg/m³Greatly, the Deflection Modulus of Elasticity that can make hard polyurethane foams is more than 15MPa.Therefore, may be used To eliminate the density unevenness of polyurethane, the problem of heat insulating box that spills etc of polyurethane, be obtained in that reliability is high, high intensity Heat insulating box 700, refrigerator 1, showcase, possess the equipment of heat insulating box.

Here, worrying that the free foaming density of hard polyaminoester is bigger than predetermined value, it is close to increase the polyurethane after foaming because making The impact to heat-proof quality for the degree, but as illustrated by Figure 17～Figure 21, such as by the configuration position of Vacuumed insulation panel 400 The thickness of polyurethane is set as below predetermined value (below 11mm or below 6mm) or by thickness in the thickness/wall of polyurethane Be set as predetermined value (0.3) below or by the filling rate of Vacuumed insulation panel 400 be set as preset range (more than 40% 90% with Under) when, can reduce the heat-proof quality to heat insulating box impact (to heat insulating box 700, the heat insulating box of shutter door heat-insulated The impact of performance).In addition, make polyurethane thickness be below 11mm when, by make free foaming density be predetermined value (for example 35kg/m³) more than, can be set to the lucky loading (lucky loading can be adjusted) not causing polyurethane to spill.

The heat insulating box 700 of present embodiment can make the wall ratio of heat insulating box 700 existing thin, furthermore it is ensured that in advance Fixed intensity, in filling polyurethane, polyurethane is also difficult to spill from profile, can meet required quality it is provided that saving Energy, the heat insulating box 700 of internal volume excellent in efficiency.That is, do not change heat insulating box 700 or refrigerator 1 or possess heat insulating box The appearance and size of equipment can so that heat insulating box reserve storage volume (in the case of such as refrigerator be case internal volume or Reservoir volume) bigger than existing, the storage item that the inside of heat insulating box 700 can be stored can be increased compared to existing technology.Cause This, be obtained in that user's convenient use, thermal insulation be good, high intensity and the high heat insulating box of reliability 700 or refrigerator 1 or tool The equipment of standby heat insulating box.Additionally, when the storage volume settings of indoor (storage is indoor) are become equal with prior art, can make Appearance and size correspondingly reduces the amount that wall thickness can reduce.

Here, refrigerator 1 possesses the air for cooling to the supply of multiple storeroom such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 The cooling device of (cold air).This cooling device is (swollen by compressor 12, refrigerant piping (for example condensing pipe arrangement 725), decompressor Swollen valve, capillary etc.), cooler 13 etc. constitute, form freeze cycle.Constitute the compressor in the inscape of this freeze cycle 12nd, the machinery that decompressor is formed located at the back underside (can also be on the upside of the back side) in the heat insulating box 700 forming refrigerator 1 In the 1A of room.Condensation pipe arrangement 725 is located at the such as side wall 790 of heat insulating box 700 or back face wall 730 or top wall 740.Pass through Form fan grill of reserve accommodation space etc. at the back side of storeroom, overleaf the storeroom side of wall 730 is provided with and interior case The back side cover of the part of 750 splits, cooler 13 is cold located at formed between the back side cap assembly such as interior case 750 and fan grill But in device room 131.Additionally, being additionally provided with this cooler room 131 for being sent by the chilled air of cooler 13 (cold air) Wind is to the circulating cold air fan 14 of each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5.Additionally, in heat insulating box 700 The top (or substantial middle height and position of back face wall 730) of top wall 740 or back face wall 730 is provided with control base board room 31, it is provided with control device 30 in control base board room 31, this control device 30 is controlled compressor 12 or circulating cold air wind The motion of the rotating speed of fan 14 etc. controls or the temperature inside the box controls etc..

In such refrigerator 1 constituting, the gas system of the HTHP sent by the compressor 12 being configured in the 1A of Machine Room Cryogen, refrigerant piping (such as condense pipe arrangement) 725 by and be condensed, become the liquid refrigerant of cryogenic high pressure, low temperature The liquid refrigerant of high pressure reduces pressure into the gas-liquid two-phase cold-producing medium of low-temp low-pressure by decompressor, when reaching cooler 13, becomes Such as less than -20 DEG C of low temperature.The gas-liquid two-phase cold-producing medium of this low-temp low-pressure cools down the air in cooler room 131, and should Air after cooling is supplied to each storerooms such as refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 by circulating cold air fan 14, thus The storerooms such as cooling refrigerating chamber 2, refrigerating chamber 6, vegetable compartment 5 (or the storage item received in these storerooms).On the other hand, cold But the gas-liquid two-phase cold-producing medium of the low-temp low-pressure of air in cooler room 131, by the air heating in cooler room 131 Evaporation, becomes the gas shape cold-producing medium of low pressure and is inhaled into compressor 12 once again and is compressed.

As described above, in the refrigerator 1 of present embodiment, making Vacuumed insulation panel 400 with respect in outer container 710 and interior case The space 315 being formed between 750 and the ratio shared by total volume of the internal capacity of door inner space of shutter door are vacuum The filling rate of thermal insulation barriers is predetermined value (such as 40%～80%).Therefore, even if thickness is (for example outer in the wall of heat insulating box 700 Distance (thickness) between case 710 and interior case 750 or the thickness of shutter door) than prior art thin it is also possible to guarantee thermal insulation Energy.Therefore, in the refrigerator 1 of present embodiment, the heat-proof quality of heat insulating box 700 is improved, thus multiple storeroom 2, 3rd, the cold air in 4,5,6, storage item are not easy to warm, and therefore can shorten the duration of runs of the compressor 12 for cooling or subtract The air quantity of small fan.Therefore, it is possible to the air quantity of air (cold air) required for the cooling in storeroom 2,3,4,5,6 is suppressed relatively Little, the rotating speed of compressor 12 can be reduced or extend operating OFF time, therefore can carry out the operating of energy-conservation.Therefore, in this reality Apply in the refrigerator 1 of mode, can be than existing energy-conservation.Additionally, refrigerator 1 does not change appearance and size just can expand compared to existing technology Big reservoir volume (case internal volume), can increase the storage item that storage interior can be stored compared to existing technology, therefore can obtain Obtain refrigerator, the equipment of convenient use.

If additionally, the refrigerating chamber 6 maximum with the temperature difference of outer gas is configured at the substantial middle position of above-below direction, can Enough suppression from above and the heat from outer gas that enters towards refrigerating chamber 6, heat therefore can be made to invade refrigerating chamber 6 from outer gas Hot entering surface is 4 faces (shutter door above, left surface, right flank, this 4 face of the back side).Thus, it is possible to obtain the refrigerator 1 of energy-conservation.

Additionally, according to present embodiment, making to be filled in the bending resistance of the hard polyurethane foams of space 315 and door inner space Elastic modelling quantity is more than 15.0MPa, and the casing intensity of therefore heat insulating box 700 can meet predetermined intensity, such that it is able to press down Heat insulating box 700 processed deforms because of cause crooked of the weight that cannot tolerate storage item.Therefore, it can suppress heat insulating box 700 Crooked and so that shutter door above is tilted, the deterioration of outward appearance can be prevented.Furthermore, it is possible to suppression is to shutter door and heat insulating box Stagger and produce gap so that refrigerating chamber 2, refrigerating chamber 6, vegetable in the position of the seal member being sealed between front openings portion The situation that dish room 5, ice-making compartment 3, the air (cold air) in switch room 4 spill to the outside of heat insulating box 700, refrigerator 1, so as to Enough obtain more energy efficient refrigerator, equipment.

In addition, distribution with regard to the filling rate of the Vacuumed insulation panel 400 in space 315 or door inner space it is also possible to According to the temperature difference of outer gas and each storeroom, and to change true in space 315 or door inner space according to predetermined position The filling rate of empty thermal insulation barriers 400.
