Summary of the invention
Subject to be solved by the invention
Vacuumed insulation panel has such as 6 times or more of thermal insulation compared to the heat-proof quality of existing hard polyurethane foams
Energy.Therefore, from the angle of energy-saving grade, in the space being formed between outer container and interior case, in addition to configuring hard polyurethane
Ester foam, also configures Vacuumed insulation panel.Also, with the raising of the requirement of energy-saving in recent years, such as described in patent document 1
Heat insulating box is such, and the usage amount for being configured at the Vacuumed insulation panel of heat insulating box also increases.
On the other hand, in recent years for heat insulating box, from space saving, the angle of the high capacity of internal volume, also
It is required that reducing the wall thickness in the space, i.e. heat insulating box that are formed between outer container and interior case.But existing heat insulating box is to be based on
What technical idea below was made: hard polyurethane foams mainly undertake heat insulating function, and Vacuumed insulation panel assists hard poly-
The heat insulating function of urethane foam.Here, hard polyurethane foams by being filled by existing heat insulating box with scheduled density
Space between interior case and outer container and obtain cabinet intensity, but in thickness of the thickness of polyurethane to be reduced to reduce wall surface,
The thickness of polyurethane becomes smaller, and the density of polyurethane increases, heat-proof quality decline, needed for meeting heat-proof quality and obtaining
Cabinet intensity.
That is, existing heat insulating box, refrigerator etc. have Vacuumed insulation panel equipment in, by hard polyurethane foams come
Ensure the heat-proof quality of wall surface and cabinet and the intensity of cabinet, wall, reduces hard to reduce the wall thickness of heat insulating box and gather
The thickness of urethane foam, then can generate heat insulating box heat-proof quality is insufficient or intensity is insufficient and is difficult to realize the reduction of wall thickness
The problem of.
Here, the usage amount (covering rate) of Vacuumed insulation panel increases, hard in the heat insulating box described in patent document 1
The Deflection Modulus of Elasticity (rigidity of hard polyurethane foams) of polyurethane foam increases, therefore for the intensity face of heat insulating box
Also think that wall thickness can be reduced to a certain extent.But heat insulating box described in patent document 1 is to pass through rigid polyurethane foam
Foam mainly undertakes heat insulating function and Vacuumed insulation panel assists the technical idea of the heat insulating function of hard polyurethane foams to be made
, hard polyurethane foams mainly undertake heat insulating function, and Vacuumed insulation panel assists the heat insulating function of hard polyurethane foams, passes through
Hard polyurethane foams ensure the heat-proof quality of heat insulating box and the intensity of wall surface.However, the thickness of hard polyurethane foams
When becoming smaller, density, Deflection Modulus of Elasticity be will increase, but thermal insulation deteriorates.Therefore, in order to inhibit the heat-insulated of hard polyurethane foams
The decline of performance is set to make the Deflection Modulus of Elasticity of hard polyurethane foams, (Deflection Modulus of Elasticity below density predetermined value
10MPa or less, density 60kg/m3Below).When Deflection Modulus of Elasticity, density are more than predetermined value, although cabinet intensity is expired
Foot, but heat-proof quality deteriorates, to be difficult with.Therefore, heat insulating box described in patent document 1 is in order to ensure cabinet, wall surface
Intensity and both heat-proof qualities, therefore, to assure that the thickness of polyurethane needs to be adjusted to fill out thus more than to a certain degree
Fill the polyurethane flow path at the position of polyurethane with a thickness of it is more than scheduled thickness so that density after polyurethane foam is predetermined value
(density 60kg/m below3Below), to there are problems that being difficult to reduce wall thickness.
In addition, intensity measure of the patent document 2 as the heat insulating box for having Vacuumed insulation panel, has used following vacuum
Thermal insulator, interior case, outer container: for Vacuumed insulation panel outsourcing material by plastic material etc. by vacuum forming, compressed air at
Type etc. and be shaped to target shape, granular core material is filled with, to be shaped to ensure the concaveconvex shape of intensity.But
In being the convex-concave profile for the basic similar shape of bumps for making interior case, outer container and the outsourcing material of Vacuumed insulation panel and insertion and making
Case and outer container have intensity, cause the shape of outsourcing material, interior case, outer container to become complicated in this way, there are costs to increase, assemblability
The problems such as deterioration.In addition, Vacuumed insulation panel is also required to outsourcing material being shaped to concave-convex from the angle for ensuring intensity
Shape, the core material in enclosed outsourcing material be also required to be according to the shape of the concaveconvex shape of outsourcing material, therefore core material need using
Shot-like particle with mobility, compared with the fiber-likes core material such as glass fibre, cost increase, heat-proof quality there is also variation can
It can property.In addition, the back side of indoor (storage space of intracorporal reserve of hot box etc.) is concaveconvex shape, complex-shaped, appearance
Property be deteriorated.
Therefore, in existing heat insulating box, equipment, especially refrigerator, it is difficult to ensure scheduled heat-proof quality and predetermined
Cabinet intensity and make comprising Vacuumed insulation panel thermal wall or thermal insulator slimming, accordingly, it is difficult to realize heat insulating box, ice
The miniaturization of the further expansion or outer dimension of the internal volume of case, equipment etc..In addition, in documents 2, heat-insulated
Vacuumed insulation panel is arranged in the back face wall of cabinet (refrigerator), but the width of Vacuumed insulation panel is than the case insied width of heat insulating box (refrigerator)

The polyurethane inlet for being placed in the width direction end (or end of up and down direction) at the back side of heat insulating box will be with vacuum
Thermal insulator interference, therefore, it is impossible to increase Vacuumed insulation panel in width direction (or up and down direction), to be difficult to improve heat-insulated
Performance.
In addition, the storeroom of drawer type will be supported by screw in the refrigerator described in patent document 3, patent document 4
The track component or door frame of box body be fixed to thermal wall (polyurethane thermal insulator between interior case or interior case and outer container or
Person is set to the strengthening part between interior case and outer container).But when being configured with Vacuumed insulation panel between outer container and interior case,
In the case where the thinner thickness of thermal insulator between Vacuumed insulation panel and interior case, it is possible to because of the unevenness of the thickness of Vacuumed insulation panel
It is even etc. to lead to the damage of the fixing screws of track component or door frame or destroy the outsourcing material of Vacuumed insulation panel and cause vacuum
The decline of the heat-proof quality of thermal insulator, the decline of reliability.
In addition, in order not to damage Vacuumed insulation panel, it is contemplated that shorten the length of the threaded portion of screw, but if being filled in true
The intensity (such as density, bending resistance elasticity etc.) of polyurethane thermal insulator between empty thermal insulator and interior case is smaller, then the holding of screw
The intensity of also weaker and integrally formed with the polyurethane thermal wall of intensity is also weaker, and it is therefore possible to lead to thermal wall or case
Body deformation or screw fluff, and reliability reduces, therefore flighted length cannot be shortened to predetermined length or less.Therefore, exist
Thermal wall installation with Vacuumed insulation panel is kept by screw or embedded structure etc. or fixed another component (such as props up

It does not need between empty thermal insulator 400 with heat-insulated thermal insulator as the main purpose, and with heat-insulated sandwiched thermal insulator as the main purpose
When compared to wall thickness can be thinned, therefore storage chamber volume can be increased.Here, when needing mobility as bonding agent, it can also
To use the hard polyurethane foams etc. with self-adhesiveness, in two-phase state inflow space 315 after make its foaming to
It is bonded.
In the present embodiment, it can use as the cold air wind path 760 blowed to the cooling indoor cold air of storage
Recess portion 440, therefore the hand for being able to use family is difficult to the recess portion 440 at the storeroom back side touched and is utilized effectively, so as to
Efficiently use the indoor storage volume of storage.In addition, using the vacuum with scheduled intensity (bending strength, buckling strength)
Protrusion 450 simultaneously (is preferably able to ensure torsional strength, the journey of buckling strength by thermal insulator 400 in storeroom with scheduled width
Degree) in above-below direction continuous setting when, intensity needed for heat insulating box 700, refrigerator 1 can be obtained, and ensure torsional strength, preceding
The buckling strength of rear direction and left and right directions, therefore the heat insulating box 700 of high reliablity, refrigerator 1 can be obtained.As long as in addition,
Intensity needed for heat insulating box 700, refrigerator 1 can be obtained simultaneously ensures that the bending of torsional strength, front-rear direction and left and right directions is strong
Degree, protrusion 450 also can be set at one or are intermittently arranged many places without continuous setting in above-below direction.
In the present embodiment, the left and right end portions side (width direction end side) at the back side is formed by vertically in storeroom
The protrusion 450 that the thermal insulators 701 such as the polyurethane of direction configuration are constituted, therefore hot box can be improved by forming the protrusion 450
Body 700, the torsional strength of refrigerator 1, buckling strength.Therefore, be not in heat insulating box 700, refrigerator 1 deformation and make be set to storage
Door of storage room (such as the refrigerating-chamber door 7 of rotary (radial type)) before room (such as refrigerating chamber 2) tilts, for example split
A case where side of the door (7A, 7B) of left and right tilts and causes dislocation in the case where door, therefore can successfully carry out storeroom
The opening and closing of door.In addition, the dislocation of the door of storage room of left and right will not occur, therefore beautiful.In addition, in the case where drawer type door,
It is not in make to be set to storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, freezing chamber 6 because heat insulating box 700 deforms
Deng) the different or inclination of the mounting height of track of drawer type box body of the inner wall side wall of left and right () 791,792 or so, therefore energy
The enough discrepancy for successfully carrying out box body.
Here, in the present embodiment, the thermal insulators such as Vacuumed insulation panel 400, the polyurethane for forming protrusion 450 need predetermined
Intensity, therefore Vacuumed insulation panel 400 using Deflection Modulus of Elasticity be 20MPa or more component, formed protrusion 450 polyurethane
Etc. thermal insulators using Deflection Modulus of Elasticity be 13.0MPa or more (preferably 15MPa or more), density be greater than 60kg/m3(preferably
62kg/m3More than) component.In the past will by the thermal insulators such as polyurethane obtain both cabinet intensity and heat-proof quality, therefore from
Ensuring that the angle of cabinet intensity is set out needs to make polyurethane thermal insulator to increase Deflection Modulus of Elasticity, but the spy as hard polyaminoester
If property increases Deflection Modulus of Elasticity, density increases, and heat-proof quality declines if density increases.Therefore, the polyurethane the case where
Under, in order to obtain scheduled heat-proof quality, it is difficult to make Deflection Modulus of Elasticity about 10MPa or more, therefore, it is impossible to make polyurethane
Thickness is thinner than for example, about 15mm.Here, the thickness of polyurethane the thin, more the thickness of wall can be reduced, increase storeroom content
Product, thus it is preferred that.But in order to reduce wall thickness when the thickness of polyurethane is thinned, the density of polyurethane increases, bending resistance springform
Amount also increases, thus while being capable of increasing cabinet intensity, but heat-proof quality can deteriorate when density increase, therefore, it is difficult to make polyurethane
Thickness it is thinner than predetermined value (such as 15mm).
In the present invention, Vacuumed insulation panel 400 uses Deflection Modulus of Elasticity greatly to the component of 20MPa or more, therefore is matching
It is equipped with the part (cabinet or wall) of Vacuumed insulation panel 400, can make Vacuumed insulation panel 400 that there is heat-proof quality and intensity two
Person, even if between outer container and interior case when the thermal insulators such as filled polyurethane, at the position for being configured with Vacuumed insulation panel, without general
Polyurethane can be used as being used with heat-insulated thermal insulator as the main purpose as bonding agent.Therefore, can will gather
The thermal insulators such as urethane are as being bonded Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container 710
Bonding agent uses, therefore there is no problem the thickness for reducing polyurethane declines the heat-proof quality of polyurethane.Here, logical
Crossing makes the covering rate of Vacuumed insulation panel 400 (the configuration area of Vacuumed insulation panel 400 is relative to heat insulating box 700, the surface area of door
Ratio) or the filling rate of Vacuumed insulation panel 400 (Vacuumed insulation panel 400 is relative to the sky between outer container 710 and interior case 750
Between volume ratio shared by 315) greatly to more than predetermined value (such as 40% or more), even if in the presence of Vacuumed insulation panel 400 is not configured
Position, the heat-proof quality as heat insulating box 700, intensity is also ensured.
Therefore, it is waited as shown in the embodiment in recess portion 440 and is configured with vacuum heat-insulation between outer container 710 and interior case 750
The position of part 400, when there is intensity and both heat-proof qualities of heat insulating box 700 by Vacuumed insulation panel 400, vacuum every
Between warmware 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, it can be used as to be bonded as the main purpose
Bonding agent come using hard polyurethane foams, therefore can reduce the thickness of polyurethane, can not consider the heat-insulated of polyurethane
The decline of performance.Therefore, even if the thermal insulation for reducing wall thickness by the thickness that hard polyurethane foams are thinned, making hard polyaminoester
It can decline, since the heat-proof quality of cabinet is undertaken by Vacuumed insulation panel 400, there is no problem.Thus, it is possible to pass through reduction
The thickness of polyurethane reduces wall thickness to increase storage chamber volume.Wherein, between outer container 710 and Vacuumed insulation panel 400 or
It can be thinned when either side in person between case 750 and Vacuumed insulation panel 400 is using 2 bonding agents such as hot melt adhesive, double-sided adhesives
Wall thickness, therefore it is capable of increasing the indoor volume of storage.
Here, as between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750
The hard polyurethane foams when bonding agent used uses with a thickness of the thickness below predetermined value or less than Vacuumed insulation panel 400
When spending, wall thickness can be reduced, therefore be capable of increasing the indoor volume of storage.Here, for Vacuumed insulation panel 400 and outer container 710
Between or the either side between Vacuumed insulation panel 400 and interior case 750 use to be bonded hard polyurethane as the main purpose
When the thickness of ester foam is less than the thickness of Vacuumed insulation panel 400, the effect that can reduce wall thickness can get.If Vacuumed insulation panel
Hard polyurethane between the thickness and Vacuumed insulation panel 400 and interior case 750 of hard polyurethane foams between 400 and outer container 710
The sum of thickness of ester foam is less than the thickness of Vacuumed insulation panel 400, then can further decrease wall thickness, so as to increase storage
Indoor volume.
In the present embodiment, as between Vacuumed insulation panel 400 and outer container 710 or Vacuumed insulation panel 400 and interior
The bonding agent used between case 750 using hard polyurethane foams, and keeps the thickness of polyurethane as thin as possible.But it is not only
Between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750, in not set Vacuumed insulation panel
400 and identical hard polyurethane foams also can be used in the position (in wall) that is only filled with polyurethane.Not set Vacuumed insulation panel
400 and be only filled with the position (such as a part in wall or in protrusion) of polyurethane since there is no Vacuumed insulation panel 400, from
And the thickness of hard polyaminoester can be made to increase the amount of thickness of Vacuumed insulation panel 400, therefore the heat-insulated of polyurethane can also be increased
Thickness.Therefore, with fill between Vacuumed insulation panel 400 and outer container 710 or between Vacuumed insulation panel 400 and interior case 750
The thickness of polyurethane is compared, and can increase that there is no the thickness of the polyurethane at the position of Vacuumed insulation panel 400, thus with being configured with
The density of the polyurethane at the position of Vacuumed insulation panel 400 is compared, and the poly- ammonia at the position that Vacuumed insulation panel 400 is not configured can be reduced
The density of ester, therefore the heat-proof quality that the polyurethane at the position of Vacuumed insulation panel 400 is not configured improves, it can be ensured that scheduled property
Energy.In addition, at the position that Vacuumed insulation panel 400 is not configured the thickness of polyurethane can be increased, therefore cabinet intensity also improves.
Here, in the present embodiment, in order to meet both cabinet intensity and heat-proof quality, the covering rate (vacuum of Vacuumed insulation panel 400
Ratio of the configuration area of thermal insulator 400 relative to heat insulating box 700, the surface area of door) or Vacuumed insulation panel 400 filling
Rate (Vacuumed insulation panel 400 is relative to volume ratio shared by the space 315 between outer container 710 and interior case 750) arrives greatly predetermined value
More than.
In the present embodiment, there is heat-proof quality, cabinet intensity by Vacuumed insulation panel 400, therefore can be used
The thickness of polyurethane thermal insulator reduces and keeps the intensity Deflection Modulus of Elasticity of polyurethane thermal insulator (excellent to 13.0MPa or more greatly
Select 15MPa or more) component.In addition it is also possible to which the density using polyurethane thermal insulator is greater than 60kg/m3(preferably 62kg/m3With
On) component, therefore the thickness of polyurethane can be reduced, the wall thickness of heat insulating box 700 can also be reduced.But if as folder
If the density of the thermal insulators such as the polyurethane of component (such as hard polyurethane foams) is excessive, then it will appear following problem: (1) poly- ammonia
The injection rate of ester increases caused increased costs, and the injection pressure of (2) polyurethane increases the hair of caused polyurethane leakage
It is raw, the box deformation inhibition mold caused by blow pressure increase, cabinet pressing component when (3) are polyurethane foam etc.
Increase with the clinging force of polyurethane, bonding force, and lead to box deformation inhibition mold, cabinet pressing component etc. and is difficult to from cabinet
It falls off and (is difficult to extract from cabinet), the density of (4) polyurethane increases caused sharply deterioration of heat-proof quality etc., quality is disliked
Change, penalty, increased costs etc..Therefore, the thermal insulators such as polyurethane as sandwiched component (such as hard polyurethane foams)
Density (be in the case where foaming heat insulation part foaming after density) be 100kg/m3Preferably (preferably 90kg/m below3Below).

The length X of the packing materials such as the ester part Chong Die with Vacuumed insulation panel 400 shortens, because of the inner box side (storage from Vacuumed insulation panel 400
Hiding room side) surface become larger to heat leak caused by the heat bridge on the surface of outer container side (back side), heat-proof quality reduce, and
The length that protrusion and Vacuumed insulation panel 400 are overlapped is too short, the strength reduction of cabinet, therefore the 1st predetermined value is preferably 30mm or more
(more preferable 40mm or more).In addition, if the 2nd predetermined value is more than the 1/3 of the width of Vacuumed insulation panel 400, recess portion 440 or the
The width of 2 recess portions 441 becomes smaller, and cold air wind path 760 is unable to ensure scheduled size, therefore the 2nd predetermined value is preferably 1/3 or less.)

(wide bandgap semiconductor)
It is equipped with control device 30 in control base board room 31, and is equipped with the semiconductor fittings such as switch element, diode element,
At least part semiconductor fittings such as inverting driving circuit use wide bandgap semiconductor.Furthermore, it is possible in control device 30 only
It carries semiconductor fittings (can be only wide bandgap semiconductor), can also carry while carrying semiconductor fittings and for example control
Association accessory (such as at least one in transformer, relay, converter, power supply reactor, capacitor, current detecting accessory etc.
It is a) etc..
In the present embodiment, as the semiconductor fittings for being equipped on control device 30, (such as compressor 12, compressor are cold
But fan, inverting driving circuit semiconductor of the circulating cold air drive control of fan 14 etc. etc.) it is partly led using broad stopband
Body.In the prior art, the semiconductor fittings generally use such as inverting driving circuit accessory of control device 30 is equipped on silicon
(Si) it is the semiconductor of matrix, but uses wide bandgap semiconductor in the present embodiment, as wide bandgap semiconductor, using for example
Silicon carbide (SiC), gallium nitride (GaN), diamond, aluminium gallium nitride alloy (AlGaN) etc..
Wide bandgap semiconductor (such as silicon carbide SiC, gallium nitride, gallium nitride (GaN) etc.) is relative to silicon (Si) semiconductor
The advantages of include following 2 points.First advantage be the loss of element it is small, can high temperature movement.The calorific value of Si is more and about
100 DEG C~200 DEG C lower semiconductor reduced performances, dyskinesias, it is therefore desirable to which the fin (radiator) that heat transmission is arranged goes forward side by side one
Step radiates via air, needs storage volume for carrying fin and for the space of heat dissipation.In contrast, broad stopband half
Switching losses in the case where conductor (such as SiC) in element are smaller, energy saving, while being all difficult to send out until 300 DEG C or so
The reduction of natural disposition energy, therefore can be used in the hot environments such as Machine Room 1A.Further, since until 300 DEG C or so all
It is difficult to happen the reduction of performance, therefore there is the fin for not needing heat transmission or the fin of heat transmission can be made very small (high
Degree and size become smaller, thinning, miniaturization) the advantages of.
Second advantage is the thickness that can reduce the device that accessory is constituted as semiconductor.Wide bandgap semiconductor (such as
SiC, GaN) insulation breakdown electric field strength it is larger, therefore the pressure resistance of semiconductor is big (about 10 times of the pressure resistance with silicon (Si)),
Therefore the thickness of semiconductor devices can be made small (thin) to 1/10 or so.In the present embodiment, by using with this spy
Property wide bandgap semiconductor, the substantially miniaturization of inverting driving circuit accessory, thinning may be implemented, there is no concern that dissipating-heat environment
Structure etc., therefore the second best in quality refrigerator under the large and small type of freedom degree and hot environment that design can be obtained.
The semiconductor fittings such as the inverting driving circuit accessory of control device 30 are equipped on using wide bandgap semiconductor, therefore absolutely
Edge destruction electric field strength is big, pressure resistance is big, so as to reducing thickness and size (being about 1/10 compared with silicon).In addition, at 300 DEG C
At a high temperature of can also act, therefore the radiating fin (radiator) that semiconductor fittings can be made cooling is minimum.Therefore, for
It is equipped in the state of being equipped on control device 30 in the prior art compared to high heat dissipations of height such as other control association accessories
Inverting driving circuit accessory, that is, semiconductor fittings of device, in the present embodiment can be extreme by using wide bandgap semiconductor
Reduce height, the size (longitudinal and transverse width) (thinning, miniaturization) for making radiator and inverting driving circuit mate, therefore
To can be highly reduced in the state of being equipped on control device 30 with other control be associated with accessory (such as power supply reactor,
Capacitor, transformer, current detecting accessory etc.) same degree or the equal extent height below of height.
Here, also Vacuumed insulation panel 400 is adhered directly by bonding agent in the part configured with control base board room 31

In addition, in the present embodiment, being configured to control base board room 31 being set to the upper surface of refrigerator 1 and using Vacuumed insulation panel
400 by surrounding insulation, and when the semiconductor fittings such as inverting driving circuit accessory use wide bandgap semiconductor, even if control base board room
It is covered and is made in control base board room 31 under hot environment with Vacuumed insulation panel 400 or polyurethane thermal insulator around 31
There is no problem.In addition, when the semiconductor fittings such as inverting driving circuit accessory use wide bandgap semiconductor, it can also be by control base board
Room 31 is configured in the Machine Room 1A under hot environment.Even if wide bandgap semiconductor is compared with existing Si semiconductor in height
It acts while failure can also be not susceptible under warm environment, therefore also there is no problem with thermal insulator covering control base board room 31.In addition,
It is set when control base board room 31 is configured in the Machine Room 1A under hot environment without around control base board room 31
It sets thermal insulator etc. to be thermally shielded to prevent the temperature in control base board room 31 from becoming high temperature, therefore can simplify control base board room
Design can obtain compressor, the equipment of low cost.Further, since without heat-insulated to control base board room 31, therefore can make to control
The size of substrate room 31 processed is thinned height corresponding with the amount of thickness of thermal insulator (or reducing width, depth) and minimizes, because
When this is directly bonded Vacuumed insulation panel 400 and control base board room 31, Vacuumed insulation panel 400 and interior case 750 by bonding agent, it is not necessarily to
Polyurethane as thermal insulator is filled, therefore can reduce wall surface (such as the upper wall, back face wall that control base board room 31 is set
Deng) wall thickness, can correspondingly increase storage chamber volume (case internal volume).
In addition, the compressor 12 that can not be arranged by the relationship in space in the prior art can be set in control base board room 31
Surrounding space (such as upper space, lateral space (or surrounding space) of the terminal box of compressor 12 etc.), therefore control

The filling rate of Vacuumed insulation panel 400 in the wall formed between case 710 and interior case 750 in space 315 be (Vacuumed insulation panel 400
Ratio shared by total volume of the volume relative to space 315 in the wall formed between outer container 710 and interior case 750) it is predetermined value
(for example, 40% or more (preferably 45% or more)) above.Here, the filling rate of Vacuumed insulation panel 400 also includes vacuum heat-insulation
The volume of part 400 relative to formed door profile external door panel and door inner panel between door in space volume shared by ratio be
The filling rate of door.
In the prior art, so that Vacuumed insulation panel is relative to area ratio shared by the surface area of outer container 710 or interior case 750
Example (covering rate) mode within a predetermined range configures Vacuumed insulation panel, the thickness without considering Vacuumed insulation panel 400
It influences, therefore keeps the thickness of hard polyurethane foams bigger than the thickness of Vacuumed insulation panel 400, to be ensured by hard polyaminoester
The intensity of heat insulating box.To increase the covering rate of Vacuumed insulation panel 400 in the prior art to improve the heat-proof quality of cabinet, but simultaneously
The filling rate of Vacuumed insulation panel 400 is not increased to improve heat-proof quality and cabinet intensity both sides, therefore Vacuumed insulation panel 400 is filled out
It is smaller (such as the filling rate in existing refrigerator is about 20%) to fill rate, the case where raising there are heat-proof quality, and cabinet is strong
Degree depends on hard polyurethane foams.In the present embodiment, to consider the side of the filling rate of the thickness of Vacuumed insulation panel 400
Formula configures Vacuumed insulation panel 400, therefore will not improve heat-proof quality as prior art.By making Vacuumed insulation panel
400 filling rate is predetermined value or more (such as 40% or more), and heat-proof quality is improved, and can be to meet cabinet strong
Wall thickness is thinned while degree, heat-proof quality, therefore is capable of increasing storage chamber volume, it can will be in the storeroom required by product
Volume settings are scheduled capacity or more.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.
The filling rate for increasing the Vacuumed insulation panel 400 in space 315 compared with prior art in this way, so that heat-proof quality
It increases, therefore even if the wall thickness of heat insulating box 700 is thinned compared with prior art, can also ensure that heat-insulated compared with prior art
Performance is the equal extent of the prior art or more.

Whole inner faces in face are advisable.At this point, lighting device (case intraoral illumination) is if 900 are configured at the roof 740 or underside wall of forming chamber
780, then when making the 1st wind path accessory 762 as cover member reach side wall 790, side wall is set to by lighting device 900
The case where 790 inner face, is compared, and cuts or be arranged opening without that will be equipped with the 1st wind path accessory 762 of part of lighting device 900,
Therefore it is become easy as the shape of the Appearance Panel (the 1st wind path accessory 762) of cover member, the hot box of low cost can be obtained
Body, refrigerator, equipment.Here, the Appearance Panel as cover member can be formed as covering the roof 740 and back face wall of forming chamber
730 at least part or whole inner face sides of wall surface.
(filling rate of the thickness of polyurethane, Vacuumed insulation panel)
Here, the relationship of the intensity of filling rate and cabinet to Vacuumed insulation panel 400 is illustrated.Figure 15 is to indicate hard
The figure of the relationship of the density and thermal conductivity of polyurethane foam, Figure 16 are the density and bending resistance springform for indicating hard polyurethane foams
The figure of amount, Figure 17 are the relationships of the flow path thickness of polyurethane when indicating to be filled with hard polyaminoester and the thermal conductivity of polyurethane
Figure, Figure 18 is the relationship of the flow path thickness of polyurethane when indicating to be filled with hard polyaminoester and the Deflection Modulus of Elasticity of polyurethane
Figure.Figure 15~Figure 18 is the mould filled hard polyaminoester between two faces with predetermined gap (flow path) and it is made to foam
Experimental result under quasi- structural body, the face of the side of flow path are steel plate (such as Vacuumed insulation panel or the formation as the 1st component
The coated steel plate of profile, that is, outer container 710 of the heat insulating box 700 of refrigerator 1), the face of the other side of flow path is as the 2nd component
Resin (for example, ABS used in interior case 750 (acrylonitrile, butadiene, styrene copolymerization resin), EPS (foaming modeling
Material) etc. resins).
In Figure 15, horizontal axis indicates the density (kg/m of hard polyurethane foams3), the longitudinal axis indicates leading for hard polyurethane foams
Heating rate [W/ (mK)].In addition, horizontal axis indicates the density (kg/m of hard polyurethane foams in Figure 163), the longitudinal axis indicates that hard is poly-

The thermal conductivity [W/ (mK)] of longitudinal axis expression hard polyurethane foams.In Figure 18, horizontal axis indicates filling hard polyurethane foams
Flow path thickness (mm), the longitudinal axis indicate the Deflection Modulus of Elasticity (MPa) of hard polyurethane foams.Here, filling rigid polyurethane foam
The flow path thickness of foam indicates the thickness of filling hard polyurethane foams and the hard polyurethane foams of the state to have foamed in flow path
Degree.
According to Figure 15, Figure 16, hard polyurethane foams thermal conductivity, Deflection Modulus of Elasticity when density is bigger is bigger, close
It is smaller that degree gets over hour thermal conductivity, Deflection Modulus of Elasticity.That is, density and thermal conductivity or density and Deflection Modulus of Elasticity are positive substantially
The relationship of ratio.
According to Figure 17, Figure 18, hard polyurethane foams (or are filled hard in the flow path thickness of filled polyurethane in flow path
The thickness of the polyurethane of matter polyurethane foam and the state to have foamed) it is narrower when thermal conductivity it is bigger, in addition, Deflection Modulus of Elasticity
It is bigger.Therefore, the thickness of the polyurethane after foaming in flow path is thicker, and thermal conductivity is smaller, and heat-proof quality is higher, but bending resistance elasticity
Modulus is smaller, and intensity is lower.Therefore, when reducing the thickness of polyurethane so that wall thickness is thinned, Deflection Modulus of Elasticity increases, therefore
There is no problem in intensity, but thermal conductivity becomes excessive, and heat-proof quality deteriorates, therefore the thickness of polyurethane can not be made to be less than certain journey
It spends (such as 15mm).
Here, in Figure 17, Tu18Zhong, if flow path thickness (or the polyurethane in flow path after foaming of filled polyurethane
Thickness) narrow, then density increases, if density increases, thermal conductivity as shown in figure 15 increases, and heat-proof quality deteriorates.Here, as schemed
Shown in 17, if the flow path thickness (or thickness of the polyurethane in flow path after foaming) of filled polyurethane becomes predetermined thickness (example
Such as 11mm) hereinafter, if thermal conductivity increased dramatically, heat-proof quality deteriorate.Hard polyurethane foams are forming the 1st of polyurethane flow path
It foams between component and the 2nd component and is solidified in the state of being adhered to the 1st component and 2 component, at this point, polyurethane forms core
Layer simultaneously forms the boundary layer for being known as cortex in the two sides of the sandwich layer (the 1st component side and the 2nd component side).
Figure 23 A and Figure 23 B are the schematic diagrames of the cross sectional shape after hard polyurethane foams foaming, and Figure 23 A is indicated the 1st
The schematic diagram in section when being filled with hard polyurethane foams 701A between component (interior case 750) and the 2nd component (outer container 710),
Figure 23 B is to indicate to be folded with the 3rd component (Vacuumed insulation panel between the 1st component (interior case 750) and the 2nd component (outer container 710)
400) schematic diagram in section when being filled with hard polyurethane foams 701A between 1 component of Shi and the 3rd component.
In Figure 23 A, has the thermal wall of foam filled polyurethane between the 1st component and the 2nd component successively by the 1st
Component (case 750 in such as), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex 701D, the 2nd component (such as outer container 710) are constituted.
On the other hand, as shown in fig. 23b, configured between the 1st component (interior case 750) and the 2nd component (outer container 710) as the 3rd component
When Vacuumed insulation panel 400, thermal wall is successively by the 1st component (interior case 750), the 1st cortex 701B, sandwich layer 701C, the 2nd cortex
701D, the 3rd component (Vacuumed insulation panel 400), the 2nd bonding agent 715, the 2nd component (outer container 710) are constituted.In addition, the 1st cortex
701B, sandwich layer 701C and the 2nd cortex 701D constitute hard polyurethane foams 701A.
Cortex is formed in the 1st component nearby or the 2nd component is nearby or near the 3rd component, the flow path thickness of polyurethane
When (thickness of polyurethane) is range i.e. about 20mm~30mm that the prior art uses, thickness of the thickness of cortex relative to sandwich layer
It is sufficiently small, the influence very little to density, thermal conductivity etc., but if polyurethane with a thickness of predetermined thickness (such as 11mm) hereinafter, if
Ratio shared by thickness of the thickness of cortex relative to sandwich layer becomes larger, to the density of polyurethane, thermal conductivity, Deflection Modulus of Elasticity
Influence increased dramatically, and density, thermal conductivity, Deflection Modulus of Elasticity sharply become larger.Therefore, heat-proof quality sharply deteriorates.In addition, as schemed
Shown in 18, since the density of polyurethane rises, the Deflection Modulus of Elasticity of polyurethane is also steeply risen.
Therefore, in the prior art, if reducing the thickness of polyurethane, Deflection Modulus of Elasticity increases, intensity improves, but poly- ammonia
The thermal conductivity of ester rises, heat-proof quality deteriorates, therefore can not reduce the thickness of polyurethane, and the range in about 15mm~30mm makes
With.In the prior art, it is configured in such a way that polyurethane is main thermal insulator, Vacuumed insulation panel is auxiliary thermal insulator, therefore
The heat-proof quality of polyurethane thermal insulator determines the thickness of polyurethane in the range of will not deteriorating, even if also ensuring that in narrow part
About 15mm~20mm.
But in the present embodiment, it is main thermal insulator with Vacuumed insulation panel and cabinet is ensured by Vacuumed insulation panel
The mode of intensity forms thermal wall, therefore the hard polyaminoester of the part configured with Vacuumed insulation panel do not require heat-proof quality,
To which even if for scheduled thickness (such as 11mm, preferably 6mm), also there is no problem below, more thin then Deflection Modulus of Elasticity rising,
Cabinet intensity improves, therefore better.It is scheduled with a thickness of 11mm or less when, influence of the thickness of cortex to sandwich layer becomes larger, thermally conductive
Rate increased dramatically, and heat-proof quality drastically reduces, thus be difficult to make in the prior art hard polyurethane foams with a thickness of 11mm with
Under.In the prior art, about the thickness of hard polyurethane foams, though part small range can make predetermined value 11mm with
Under, it is also difficult to make average with a thickness of 11mm or less.In turn, if scheduled with a thickness of 6mm hereinafter, if cortex thickness to sandwich layer
Influence further increase, heat-proof quality more deteriorates, therefore is difficult in the prior art.But in the present embodiment, make
Vacuumed insulation panel 400 ensures the heat-proof quality of heat insulating box 700, thus even if the thickness that polyurethane is thinned come using do not ask
Topic.Therefore, in the present embodiment, by the way that the thickness of hard polyurethane foams is set as 11mm or less (preferably smaller than
10mm), the Deflection Modulus of Elasticity of hard polyurethane foams can be increased, improve the intensity (rigidity) of cabinet 700.In addition, if will
The thickness of hard polyurethane foams is set as 6mm hereinafter, the Deflection Modulus of Elasticity of hard polyurethane foams can be further increased,
Therefore the intensity (rigidity) of cabinet 700 is further enhanced.
In addition, the thickness of polyurethane can be with the thickness of Vacuumed insulation panel in the part that Vacuumed insulation panel 400 is not configured
(for example, about 15mm~30mm) amount is formed thicker, therefore the thickness of polyurethane may insure about 20mm~40mm, can not be
The range (the thickness 11mm or less of polyurethane) that the thermal conductivity of polyurethane steeply rises uses, can be in the thermal conductivity of polyurethane
The small range of rising degree (slope) (such as range with a thickness of such as 15mm or more of polyurethane) uses, therefore even if considers
The uneven thickness of polyurethane can also ensure that the heat-proof quality of polyurethane is predetermined value or less.Therefore, it can satisfy heat insulating box
700 intensity and the heat-proof quality both sides of heat insulating box 700.
Here, in the 1st component that the face of the side of polyurethane flow path uses, using resin (for example, interior case 750 is used
ABS (acrylonitrile, butadiene, styrene copolymerization resin) or EPS (resins such as foamed plastic)).Flow path it is another
The face of side is used as steel such as the aluminium-vapour deposition film of the outsourcing material of Vacuumed insulation panel, the coated steel plates (PCM) of formation outer container 710
Plate.
It will be illustrated next in the part (such as recess portion 440 or second recesses 441 etc.) for being configured with Vacuumed insulation panel 400, gather
The thickness of urethane relative to the thermal wall for having polyurathamc and Vacuumed insulation panel 400 thickness (thickness of Vacuumed insulation panel+
The thickness of polyurethane) ratio (thickness of=polyurethane/(thickness of polyurethane+Vacuumed insulation panel thickness)) and composite guide heating rate
The relationship of (by the thermal conductivity of thermal wall made of Vacuumed insulation panel and polyurethane composition).
Figure 19 is to indicate the thickness of polyurethane when wall thickness (thickness between the inner wall of wall) is fixed as 27mm relative to by vacuum
The ratio of the thickness of thermal insulator made of thermal insulator and polyurethane composition, the figure with the relationship of composite guide heating rate.It is horizontal in Figure 19
Axis indicate polyurethane thickness relative to by the ratio of the thickness of thermal insulator made of Vacuumed insulation panel and polyurethane composition, i.e. gather
The thickness of urethane/(thickness of polyurethane+Vacuumed insulation panel thickness), the longitudinal axis indicate that composite guide heating rate (by Vacuumed insulation panel and gathers
The thermal conductivity that urethane combines).Here, by total, the i.e. polyurethane of the thickness of the thickness of polyurethane and Vacuumed insulation panel
Thickness+Vacuumed insulation panel thickness is as thickness in wall.
It appears from figure 19 that when the thickness of polyurethane is smaller, composite guide heating rate becomes smaller, heat-proof quality relative to thickness in wall
It improves.Here, composite guide heating rate indicates the thermal conductivity for the composite component for being composed polyurethane and Vacuumed insulation panel.In figure,
Thickness changes with 0.3 for boundary's slope in thickness/wall of polyurethane, is greater than 0.3 phase with thickness in thickness/wall of polyurethane
Than for thickness at about 0.3 or less, slope is smaller in thickness/wall of polyurethane, and the reduced ratio of composite guide heating rate is smaller.Figure
For the experimental verification of one timing of thickness in wall, thus in thickness/wall of polyurethane thickness ratio it is smaller, the thickness of polyurethane is got over
It is small, on the contrary the thickness of Vacuumed insulation panel is bigger, therefore the thickness of Vacuumed insulation panel is bigger relative to ratio shared by thickness in wall.
That is, relative to thickness in wall, when the thickness of polyurethane becomes smaller, the ratio of the thickness of Vacuumed insulation panel relative to the thickness of polyurethane
Increase.In figure, in thickness/wall of polyurethane with a thickness of about 0.6 at, the thickness of polyurethane is bigger than the thickness of Vacuumed insulation panel,
Therefore thermal conductivity being affected to composite guide heating rate (thermal conductivity of Vacuumed insulation panel and polyurethane altogether) of polyurethane, it is multiple
It is also larger (heat-proof quality is poor) to close thermal conductivity.If reducing thickness in thickness/wall of polyurethane, the thickness of Vacuumed insulation panel is opposite
Increase in the ratio of the thickness of polyurethane, therefore compare the thermal conductivity of polyurethane, the thermal conductivity of Vacuumed insulation panel is to composite heat-conducting
Rate is affected, as a result, as thickness/(thickness+Vacuumed insulation panel thickness of polyurethane) of polyurethane becomes smaller, polyurethane
The thermal conductivity (composite guide heating rate) for the composite component being composed with Vacuumed insulation panel reduces.Here, until polyurethane thickness/
When (thickness+Vacuumed insulation panel thickness of polyurethane) is about 0.3, compared to the thermal conductivity of polyurethane, Vacuumed insulation panel it is thermally conductive
Rate is affected to composite guide heating rate, therefore the reduction ratio of composite guide heating rate is also larger, thickness/(polyurethane of polyurethane
Thickness+Vacuumed insulation panel thickness) it is smaller, composite guide heating rate is smaller, and heat-proof quality greatly improves.
But from the thickness of polyurethane relative to the ratio of thickness in wall, i.e. polyurethane thickness/(thickness of polyurethane+
The thickness of Vacuumed insulation panel) be less than about 0.3 when from, the reduced slope of composite guide heating rate changes, the drop of composite guide heating rate
Low slope becomes smaller (the reduced ratio of composite guide heating rate becomes smaller).This is considered as since the thickness of polyurethane is relative to wall
Thickness becomes smaller in thickness/wall of the ratio of interior thickness, i.e. polyurethane, thus relative to composite component (by polyurethane and vacuum every
The component that warmware is composed) heat-proof quality, the heat-proof quality of Vacuumed insulation panel becomes overriding, the thermal insulation of polyurethane
It can become smaller to the influence of the heat-proof quality of composite component.Therefore, in the present embodiment, by composite component (polyurethane and true
The heat insulating member of the adjacent formation of empty thermal insulator both sides) thermal wall that is formed so that in thickness/wall of polyurethane with a thickness of 0.3 with
Under mode when setting the thickness of polyurethane, the reduced ratio of heat-proof quality becomes smaller, therefore even if the thickness of polyurethane or
The thickness of Vacuumed insulation panel generates unevenness, the unevenness of heat-proof quality can also be made smaller, therefore preferably.Conversely, can also be by vacuum
Thickness is set as 0.7 or more in thickness/wall of thermal insulator.
Therefore, by the thickness/wall for making polyurethane with a thickness of about 0.3 it is below in a manner of set the thickness of polyurethane when, can
To reduce composite guide heating rate, the heat-proof quality of composite component is largely increased.In addition, if considering the unevenness of the thickness of polyurethane
(or unevenness of the thickness of Vacuumed insulation panel) is set so that thickness is in 0.3 model below in thickness/wall of polyurethane
In enclosing, even if then the thickness of polyurethane, the thickness generation of Vacuumed insulation panel are uneven, it is also able to suppress the heat-proof quality of composite component
Reduction, and be able to suppress the unevenness of the composite guide heating rate of composite component, thus can obtain high reliablity, it is high performance every
Hot wall, heat insulating box, refrigerator, equipment etc..
Figure 20 is to indicate the volume of Vacuumed insulation panel 400 relative to ratio shared by the volume in space 315 in wall i.e. vacuum
The filling rate of thermal insulator, with to heat insulating box 700 apply load (load) when heat insulating box deflection relationship figure.?
In Figure 20, horizontal axis indicates that the filling rate of Vacuumed insulation panel, the longitudinal axis indicate the deflection of heat insulating box.Here, Vacuumed insulation panel
Filling rate is ratio (ratio) of the volume shared by Vacuumed insulation panel 400 relative to the volume in the space 315 in wall, heat insulating box
Deflection be about 1/4 left on the side apart from cabinet in the state of having door in the heat insulating box of such as refrigerator 1 etc.
Right height and position is applied with predetermined negative in a generally horizontal direction (laterally, being left and right directions when front openings portion is observed in front)
The calculated result of the upper end position of the side wall 790 of the cabinet 700 when load deflection of (transverse direction) in left and right directions, if vacuum heat-insulation
The deflection when filling rate of part 400 is 20% is 1.Figure 20 is the covering rate (such as 65%) for making Vacuumed insulation panel, polyurethane
Density (such as 60kg/m3), the Deflection Modulus of Elasticity (example of the Deflection Modulus of Elasticity (such as 9MPa) of polyurethane, Vacuumed insulation panel
Such as 15MPa), the thickness (such as 28mm) of composite component, the wall thickness (such as 30mm) for the thickness that added outer container and interior case it is solid
Determine and make the thickness change of Vacuumed insulation panel to change Vacuumed insulation panel filling rate when result.
In Figure 20, the filling rate of Vacuumed insulation panel is bigger, and box deformation amount is smaller.This be considered as due to, vacuum every
The Deflection Modulus of Elasticity of warmware is bigger than the Deflection Modulus of Elasticity of polyurethane, thus with the volume of Vacuumed insulation panel relative to heat-insulated
The ratio of the intracorporal polyurethane volume of case increases, and the influence of the Deflection Modulus of Elasticity of Vacuumed insulation panel becomes larger, the rigidity of cabinet 700
Increase.When the filling rate of Vacuumed insulation panel 400 is 40% or more, the reduction ratio of the deflection of cabinet becomes minimum, even if very
The filling rate of empty thermal insulator increases, and box deformation amount also hardly happens variation.This is considered as due to Vacuumed insulation panel 400
For cabinet intensity (deformation of cabinet) influence degree substantially close to saturation.
The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 is bigger than hard polyurethane foams, therefore by increasing Vacuumed insulation panel
400 volume can subtract relative to ratio shared by the volume in space 315 (ratio) (filling rate for increasing Vacuumed insulation panel)
The deflection of small heat insulating box 700, therefore can be improved the heat-proof quality of heat insulating box 700, increase heat insulating box 700 or ice
The cabinet intensity of case 1 or equipment.At this point, if increasing the thickness of Vacuumed insulation panel 400 to increase filling rate, it will be able to realize
Heat-proof quality is improved while the effect that the intensity of cabinet improves.Here, can be increased by increasing the thickness of Vacuumed insulation panel
The filling rate of big Vacuumed insulation panel, can also be by increasing surface area of the surface area of Vacuumed insulation panel 400 relative to cabinet 700
Ratio (covering rate of Vacuumed insulation panel) Lai Zeng great Vacuumed insulation panel filling rate, the intensity of cabinet can also be increased at this time,
Also, by the covering rate for increasing Vacuumed insulation panel 400, the filling rate of Vacuumed insulation panel can be increased.In addition, if increasing vacuum
The covering rate of thermal insulator 400, then the configuration range (configuration position) of Vacuumed insulation panel increases, and heat insulating box 700 can be thinned
Wall thickness, therefore the amount of storeroom internal volume increase wall thickness reduction can be made.
In the present embodiment, for example, in the outer container 710 for forming the profile of heat insulating box and the storage for forming heat insulating box
At least part in the space 315 between the interior case 750 of a part of the inner wall of room has Vacuumed insulation panel 400, makes space 315
The filling rate of interior Vacuumed insulation panel 400 is 40% or more, and makes Vacuumed insulation panel 400 relative to the surface area of outer container 710
Area ratio (covering rate) is 60% or more, so as to obtain heat-proof quality is high, cabinet intensity also it is big and high reliablity every
Hot tank body, refrigerator, equipment etc..Here, in the present embodiment, being configured to by Deflection Modulus of Elasticity than existing heat insulating box institute
Hard polyurethane foams high Vacuumed insulation panels 400 undertakes the wall surface intensity of heat insulating box 700, therefore can expire simultaneously
Sufficient cabinet intensity and heat-proof quality, and wall thickness can be thinned, therefore storage chamber volume can also increase.
The heat insulating box 700 of present embodiment is by by the bending strength Vacuumed insulation panel 400 higher than hard polyaminoester
Filling rate is set as predetermined value or more (or in preset range) or the filling rate of Vacuumed insulation panel 400 and covering rate is double
Side is set as predetermined value or more (or in preset range), can meet heat-proof quality and cabinet intensity simultaneously and can be thinned
The wall thickness of heat insulating box 700.Therefore, without change heat insulating box 700, refrigerator 1 outer dimension can expand storage it is indoor
Internal volume can increase storage item, the reserve that can be stored in the inside of heat insulating box 700 or refrigerator 1 or equipment.
In addition, when wall strength reduction, it may occur that the skew of heat insulating box 700, for example fall set on internal 80 offset track portion of shelf,
Or the storeroom (the either door of drawer type or box body or shutter door etc.) of drawer type sliding property be deteriorated the problems such as.But at this
In embodiment, since the filling rate of Vacuumed insulation panel 400 and/or covering rate are set as predetermined value or more (preset range
It is interior), therefore the wall thickness of heat insulating box 700 can be thinned, and cabinet intensity and heat-proof quality can be improved, therefore be able to suppress
The generation of following situations: 80 offset track portion of shelf and fall or the storeroom of drawer type (either door or box body or opening and closing
Door etc.) sliding property be deteriorated, cause reliability to reduce.
In addition, the heat insulating box 700 of present embodiment 1 makes the filling rate 90% of the Vacuumed insulation panel 400 in space 315
Below.According to the technical idea of above-mentioned present embodiment, it is generally desirable to all Vacuumed insulation panels 400 in space 315.But
That as illustrated by Figure 11 etc., overleaf wall 730 is equipped with protrusion 450 or protrusion 910, furthermore make to be formed in
The orbit portion 755 of case 750 is protrusively provided into space 315, when heat insulating box 700 being furthermore used for such as refrigerator 1, in wall
The pipe 720 of storage harness is also configured in space 315, therefore, it is difficult to make the filling rate of Vacuumed insulation panel 400 be more than 90%,
Above-mentioned harness is by will store in the compressor 12 carried in the Machine Room 1A for connecting heat insulating box 700, control base board room 31
Control device 30 (such as device of revolving speed etc. of control compressor) etc. wiring class boundling made of.In addition, by hot box
When body 700 is applied to such as refrigerator 1, refrigerant piping 725 etc. is also configured in space 315.Therefore, in space 315
Vacuumed insulation panel 400 is inside configured more than 90%, it is necessary to the shape with wiring class 720, refrigerant piping 725, orbit portion 755 etc.
The matched Vacuumed insulation panel 400 of shape, the shape of Vacuumed insulation panel 400 become complicated, thus Vacuumed insulation panel 400 molding (or
Person is formed) it becomes difficult, therefore the filling rate of Vacuumed insulation panel 400 is set as 90% or less.
In addition, the problem of skew occurs in order to inhibit the strength reduction of heat insulating box 700, need to make outer container 710 and interior
Case 750 is Nian Jie with Vacuumed insulation panel 400 and ensures adhesive strength, and is equipped in interior case 750 for keeping being set to storeroom (example
Such as refrigerating chamber 2) in the orbit portion 755 of shelf 80, other accessories (such as lighting device 900 or mist device 200 or separate
Wall 24 etc.) the case where it is more, it is complex-shaped.Therefore, even it is easy to Vacuumed insulation panel 400 passing through hot melt adhesive, double-sided adhesive etc.
2nd bonding agent is adhered to 710 side of outer container, it is also difficult to so that Vacuumed insulation panel 400 is adhered to complex-shaped 750 side of interior case and obtain
Adhesive strength.
But using hard polyurethane foams as the bonding agent between interior case 750 and Vacuumed insulation panel 400 in use, can
So that it is filled while the flowing of two-phase state in space 315, foaming, therefore even if there are protrusions in space 315
450, polyurethane can also be passed through when protrusion 910, orbit portion 755, other accessories without problems by interior case 750 and vacuum heat-insulation
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.At this point, being not filled by hard polyurethane foams if generating in heat insulating box 700
Be not filled by portion (i.e. gap), then the heat-proof quality of heat insulating box 700 can reduce.Therefore, in the heat insulating box of present embodiment
In 700, therefore, to assure that for (for example, about 1mm or more, preferably of a degree of predetermined gap needed for filling hard polyurethane foams
About 3mm or more), therefore the filling rate of the Vacuumed insulation panel 400 in space 315 can be for 90% hereinafter, preferably 80% or less.
However, if increasing the filling rate of the Vacuumed insulation panel 400 in space 315, 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 cabinet strength reduction of hot tank body 700.But the heat insulating box 700 of present embodiment is by using heat-proof quality, bending rigidity
All Vacuumed insulation panels 400 better than polyurethane, can inhibit the reduction of cabinet intensity.In addition, in the present embodiment, technology is thought
Want mainly to undertake heat insulating function and intensity by the small Vacuumed insulation panel 400 of thermal conductivity, therefore as shown in figure 20, by making vacuum
The filling rate of thermal insulator is 40% or more, even if the loading of hard polyaminoester is reduced, can also be improved the intensity of cabinet 700.
In addition, as shown in figure 19, by thickening the thickness (filling rate for increasing Vacuumed insulation panel) of Vacuumed insulation panel 400, can subtract
The composite guide heating rate of the small compound heat-insulation part for being composed Vacuumed insulation panel and hard polyurethane foams, therefore cabinet 700
Heat-proof quality also improves.
Here, hard is poly- if increasing the density of hard polyurethane foams to increase Deflection Modulus of Elasticity (bending rigidity)
The heat-proof quality of urethane foam itself can reduce, but by make covering rate and the filling rate predetermined value of Vacuumed insulation panel 400 with
On, the reduced influence of the heat-proof quality of polyurethane can become smaller without becoming problem.In the heat insulating box 700 of present embodiment
In, as shown in figure 16, by make hard polyurethane foams the density ratio prior art it is big, be greater than 60kg/m3, can make
The Deflection Modulus of Elasticity of hard polyurethane foams is the bending resistance bullet than hard polyurethane foams used in existing heat insulating box
The big 15MPa or more of property modulus (for example, about 6~10MPa), can also improve the cabinet that the part of Vacuumed insulation panel 400 is not configured
Intensity.Therefore, the equipment such as heat insulating box 700, refrigerator 1, showcase, hot water supply device of present embodiment, by making vacuum heat-insulation
The filling rate of part 400 is 40% or more, makes 70% or more the laterodorsal covering rate of Vacuumed insulation panel, is able to suppress because of hard
Strength reduction caused by the reduction of the filling rate of polyurethane foam, additionally it is possible to inhibit heat insulating box 700 because storage can not be resistant to
Skew caused by the weight of object and deform.That is, heat insulating box 700 can be improved by the filling rate for increasing Vacuumed insulation panel 400
Intensity, furthermore, it is possible to obtain excellent heat-proof quality, therefore high reliablity can be obtained and energy-efficient have Vacuumed insulation panel
Heat insulating box, have Vacuumed insulation panel refrigerator, have the showcase of Vacuumed insulation panel, have the supplying hot water of Vacuumed insulation panel
Device, the equipment for having Vacuumed insulation panel etc..
In addition, the density of hard polyurethane foams adjusts, such as can be by the hard polyurethane that makes to be injected into space 315
The amount of the stoste of ester foam fill more than the prior art (lengthen injection length or increase injection pressure) and by density tune
It is larger or smallerly whole.In addition, the Deflection Modulus of Elasticity of hard polyurethane foams as shown in figure 16 with the size of density substantially at
Increase to direct ratio, therefore increase density to increase Deflection Modulus of Elasticity, and when Deflection Modulus of Elasticity is larger, gear housing rigidity increases
Greatly, therefore preferably, but the Deflection Modulus of Elasticity of polyurethane is preferably 150MPa or less.The bending resistance springform of hard polyurethane foams
Amount is if more than 150MPa, then the density of hard polyurethane foams becomes excessive, can not be foamed into spongy and solidify, thermal insulation
It can drastically reduce, therefore when Deflection Modulus of Elasticity of hard polyurethane foams is 150MPa or less is able to suppress the drop of heat-proof quality
It is low to preferably, high performance heat insulating box can be obtained.In addition, if the thermal insulators such as polyurethane as sandwiched component (such as
Hard polyurethane foams) density it is excessive, then will appear following problem: (1) polyurethane injection rate increase caused by cost
Increase, the injection pressure of (2) polyurethane increases generation of the caused polyurethane from leakages such as cabinets, and (3) are sent out due to polyurethane
The clinging force of box deformation inhibition mold, cabinet pressing component caused by blow pressure increase when bubble etc. and polyurethane,
Bonding force increases, and leads to box deformation inhibition mold, cabinet pressing component etc. and be difficult to fall off from cabinet (to be difficult to pull out from cabinet
Out), the density of (4) polyurethane increases caused sharply deterioration of heat-proof quality etc., deterioration, penalty, cost increase
Add.Therefore, the density of the thermal insulators such as polyurethane as sandwiched component (such as hard polyurethane foams) (foaming heat insulation part
In the case of be foaming after density) be 100kg/m3Preferably (preferably 90kg/m below3Below).
In the present embodiment, the refrigerator by heat insulating box 700 for example applied to following specification.

Even if Vacuumed insulation panel 400 is not configured to shutter door can also ensure that sufficient heat-proof quality.Vacuumed insulation panel 400 is in outer gas
When bigger with temperature difference in heat insulating box 700 (such as in storeroom) (such as ice-making compartment 3, switch room 4, freezing chamber 6 etc. are cold
Freeze the storeroom of temperature band), if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality improves is larger.Cause
This, the feelings of the storeroom of the bigger cryogenic temperature band of temperature difference in outer gas and heat insulating box 700 (such as in storeroom)
Under condition, by the way that Vacuumed insulation panel 400 is configured at shutter door, it can be ensured that sufficient heat-proof quality.
In addition, sheets of glass also can be used in external door panel, in the case, sheets of glass is pasted by double-sided adhesive etc.
The front side of the frame portion of the resin inner part of side opening is (with inside-of-refrigerator face with face on the inside of frame portion and case and in front
Portion opposite side) opening portion replace outside plate, to form an inner space, this inner space configuration (filling) firmly
Matter polyurethane foam and Vacuumed insulation panel 400.In addition, Vacuumed insulation panel 400 on the inside of the case of inner part face by double
In the state that 2nd bonding agent such as face glue has been bonded, filling, coating or the enclosed bonding as sandwiched component in door inner space
Agent (such as hard polyurethane foams).Here, by making the bonding agent (such as hard polyurethane foams) as sandwiched component
Density is greater than 60kg/m3, the hard polyurethane foams as sandwiched component form close, and Deflection Modulus of Elasticity increases, therefore, i.e.,
Make the holding that also can be improved sheets of glass using sheets of glass or adhesive strength, in addition improve as door
The intensity (rigidity) of the hard polyurethane foams of the sandwiched component of inner space, therefore, the intensity (rigidity) of door also improve.Separately
Outside, by make sandwiched component with a thickness of 11mm or less (being, for example, less than that 10mm is advisable), be capable of increasing the bending resistance of polyurethane foam
Therefore elasticity modulus even if the thickness of polyurethane foam becomes smaller, can also be such that intensity is improved.Therefore, door thickness can be reduced
Degree and raising cabinet intensity.In addition, as sandwiched component (bonding agent) using the hard polyurethane foams with self-adhesiveness, it will
[(thickness of sandwiched component)/(thickness+Vacuumed insulation panel thickness of sandwiched component)] be set as 0.3 hereinafter, can then reduce by
Composite component with Vacuumed insulation panel 400 and hard polyurethane foams is formed by the composite guide heating rate of door, therefore even if subtracts
Heat-proof quality also can be improved in Bao Menhou.
More than, in the heat insulating box 700 of present embodiment or refrigerator 1 or equipment, relative to will be in 710 He of outer container
The spatial volume of the inner space inner space Ji Men in the space 315 and shutter door formed between interior case 750 altogether, vacuum every
The filling rate of volume ratio, that is, Vacuumed insulation panel 400 shared by warmware 400 within a predetermined range (such as 40% or more 80%
Below).Therefore, wall thickness (such as the distance between outer container 710 and interior case 750 and the shutter door of heat insulating box 700 can be made
Thickness) it is thinner than the prior art, therefore it is capable of providing heat insulating box 700, the refrigerator of energy conservation and the indoor internal volume excellent in efficiency of storage
1, equipment.Therefore, even if not changing the outer dimension of heat insulating box 700 or refrigerator 1, the internal volume in storeroom can also be made
It is bigger than existing, therefore the storage item that the inside that can increase heat insulating box 700 compared with prior art can store.Therefore, may be used
To provide heat insulating box 700 more energy saving than the prior art and that heat-proof quality is good, commodity value is high, refrigerator 1, hot water supply device, display
Cabinet, equipment.
In addition, the rigid polyurethane foam by the filling rate for increasing the Vacuumed insulation panel 400 in space 315, in space 315
The filling rate of foam reduces.In the heat insulating box 700 of present embodiment, keep the density ratio prior art of hard polyurethane foams big
(it is greater than 60kg/m3), keep the Deflection Modulus of Elasticity of hard polyurethane foams harder than used in existing heat insulating box
The big 15.0MPa or more of the Deflection Modulus of Elasticity (about 6MPa~10MPa) of matter polyurethane foam.Therefore, present embodiment every
Hot tank body 700 can also inhibit strength reduction caused by the reduction because of the filling rate of hard polyurethane foams, and hot box is not present
Body 700 becomes because that can not be resistant to the skew caused by the weight of reserve storage space or the indoor storage item of storage or shutter door
The problems such as shape, can obtain heat insulating box 700, the refrigerator 1, equipment of high reliablity.
Therefore, in the refrigerator of present embodiment 1 or have in the equipment of the heat insulating box 700 with Vacuumed insulation panel 400,
Can inhibit the phenomenon that the skew of heat insulating box 700 and make the shutter doors such as shutter door inclination can not smooth opening and closing, furthermore, it is possible to inhibit
Because of the deterioration of appearance caused by deforming.Furthermore, it is possible to prevent the gasket of shutter door and the opening portion for sealing heat insulating box
The positional relationship of contact surface (sealing surface) deviate and generate gap to making to store indoor air (to be cold in the case where refrigerator
Gas) the case where being flowed out to outside heat insulating box.It can also inhibit heat insulating box 700 using Vacuumed insulation panel 400 even if a large amount of as a result,
Reduced performance, reliability reduce, have excellent heat-proof quality, therefore can obtain energy conservation and the refrigerator of high reliablity or
Heat insulating box with Vacuumed insulation panel has the equipment of Vacuumed insulation panel, has the equipment of heat insulating box.
In addition, if the density of the thermal insulators (such as hard polyurethane foams) such as polyurethane as sandwiched component is excessive,
Will appear following problem: (1) injection rate of polyurethane increases caused increased costs, and the injection pressure of (2) polyurethane increases
Caused polyurethane from the generations of the leakages such as cabinet, blow pressure when (3) are polyurethane foam increase caused by case
Body deforms the clinging force of inhibition mold, cabinet pressing component etc. and polyurethane, bonding force increases, and box deformation is caused to inhibit
It is difficult to fall off from cabinet and (be difficult to extract from cabinet) with mold, cabinet pressing component etc., caused by the density increase of (4) polyurethane
The sharply deterioration of heat-proof quality etc., deterioration, penalty, increased costs etc..Therefore, the polyurethane as sandwiched component
Etc. the density (be in the case where foaming heat insulation part foaming after density) of thermal insulators (such as hard polyurethane foams) be 100kg/
m3Preferably (preferably 90kg/m below3Below).
Here, being the length in the height over width direction of up and down direction is big when heat insulating box 700 is as refrigerator
When elongated rectangular shape, compared to the partition wall 24 etc. between the bottom surface sections 780 of approximate horizontal configuration, top 740, storeroom,
The side wall 790 that generally perpendicularly configures, back face wall 730 are in elongated shape, therefore rigidity is weak and be easily deformed.Therefore, pass through
As in this embodiment within a predetermined range by the filling rate of Vacuumed insulation panel 400, covering rate setting, hot box can be improved
The intensity (rigidity) of body 700.In addition, can also be improved cabinet intensity by setting protrusion 450 or protrusion 910.In addition, setting
It is set to the one end for making protrusion 450 and is configured at the Vacuumed insulation panel 400 of recess portion 440 or second recesses 441 with predetermined length X weight
It is folded, and the other end is connected to side surface part 790, so as to so that Vacuumed insulation panel 400 via hard polyurethane foams and protrusion
450 is integrally formed, furthermore, it is possible to keep Vacuumed insulation panel 400 integrally formed via hard polyurethane foams and side wall 790, therefore
The intensity of cabinet 700 can be improved.
Figure 21 is to indicate Vacuumed insulation panel 400 relative to the side surface part 790 of heat insulating box 700 and the surface area institute of back part
The figure of the relationship of the area ratio (side back face covering rate) and box deformation amount that account for, is calculated result.About the strong of heat insulating box
Degree, side wall 790, back face wall 730 shape be elongated oblong-shaped, with top wall 740, underside wall 780, partition wall 24 etc.
Substantially square shape compared to rigidity it is weaker, therefore by by the side back face covering rate of Vacuumed insulation panel 400 be set as predetermined value with
On, cabinet intensity can be improved.Here, to Vacuumed insulation panel 400 relative to shared by side wall 790 and the surface area of back face wall 730
Area ratio (side back face covering rate) and the relationship of cabinet intensity be illustrated.
In Figure 21, horizontal axis indicates side wall 790 and back face wall 730 of the Vacuumed insulation panel 400 relative to heat insulating box 700
Area ratio shared by surface area (side back face covering rate), the longitudinal axis indicate the deflection of cabinet.Here, set the density of polyurethane as
60kg/m3, Vacuumed insulation panel 400 filling rate when be 40%, laterodorsal area ratio (side back face covering rate) being 50%
Box deformation amount is 1.The Deflection Modulus of Elasticity of Vacuumed insulation panel 400 used in calculating is 20MPa, is based on actual use
The measurement result of the Deflection Modulus of Elasticity of Vacuumed insulation panel uses the Deflection Modulus of Elasticity than existing hard polyurethane foams
(about 6MPa~10MPa) big component.Here, when changing area ratio (side back face covering rate), the filling of Vacuumed insulation panel
Rate is fixed as 40%, if therefore Vacuumed insulation panel area ratio (side back face covering rate) increase, the thickness of Vacuumed insulation panel
Become smaller.
In addition, as an example of refrigerator 1 for calculating, it is assumed that 4 or more (such as 4 or 5 or 6 specifications), interior
Volume is 500L grades, consumption electric power is about 40W refrigerator below.Distance including the plate thickness between outer container 710 and interior case 750
(wall thickness) average out to 30mm, it is assumed that outer container 710, interior case 750 plate thickness be respectively 1mm, so that 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/mK),
The thermal conductivity of hard polyurethane foams is 0.019 (W/mK), the heat-proof quality compared with hard polyurethane foams of Vacuumed insulation panel 400
About 10 times or so are got well.
In Figure 21, horizontal axis indicates Vacuumed insulation panel 400 relative to shared by side walls and back face wall surface area altogether
Area ratio (laterodorsal Vacuumed insulation panel covering rate), the longitudinal axis expression heat insulating box 700 with shutter door is applied with
Box deformation amount (amount of inclining of cabinet) when scheduled load.Here, the deflection of cabinet is indicated in distance such as hot box
The height and position of the upper surface of side wall of side of body about 1/4 or so (laterally, observes front openings in front in a generally horizontal direction
It is left and right directions when portion) deflection of the left and right directions of the sidewall upper of heat insulating box when being applied with scheduled load.
It is found that the area ratio of Vacuumed insulation panel 400 is bigger in Figure 21, then box deformation amount is smaller.Make side/back side
Area ratio (laterodorsal Vacuumed insulation panel covering rate) be 70% or more when, the change rate of box deformation amount becomes smaller.That is, arriving
Until side/back side area ratio is 70% or so, if area ratio becomes larger, box deformation amount sharply becomes smaller, but works as side
When face/back side area ratio becomes 70% or more, even if area ratio becomes larger, box deformation amount hardly happens variation.Cause
This, when side/back side area ratio (laterodorsal Vacuumed insulation panel covering rate) is 70% or more, the drop of the deflection of cabinet
Low ratio is minimum, even if the side back face area ratio of Vacuumed insulation panel increases, box deformation amount also hardly happens variation.This quilt
Be considered laterodorsal area ratio due to, Vacuumed insulation panel for cabinet intensity influence degree substantially close to saturation.
Here, making the filling rate of Vacuumed insulation panel be fixed as 40% to calculate, if therefore increasing matching for Vacuumed insulation panel 400
Area is set, then the thickness of Vacuumed insulation panel 400 is thinning.Side/back side area ratio to Vacuumed insulation panel is 70% or so
Until, if increase side/back side area ratio, with the thickness of Vacuumed insulation panel it is thinning caused by box deformation increase
Amount is compared, the reduction amount of the box deformation caused by the intensity raising of cabinet caused by becoming larger because of the configuration area of Vacuumed insulation panel
It is bigger, therefore the rigidity of cabinet improves, the deflection of cabinet is reduced.But side/back side area ratio of Vacuumed insulation panel
When more than about 70%, because the thickness of Vacuumed insulation panel it is thinning caused by cabinet strength reduction caused by box deformation increase
The reduction amount of box deformation caused by amount and the raising of the intensity of cabinet caused by becoming larger because of the configuration area of Vacuumed insulation panel is
The reduction degree of same degree, the deflection of cabinet becomes smaller.
In addition, keeping the thickness of Vacuumed insulation panel thinning by the configuration area ratio (covering rate) for increasing Vacuumed insulation panel
When, the thickness of polyurethane foam thickens.To configuration area ratio be 70% or so until, Vacuumed insulation panel with a thickness of predetermined thickness
Degree or more, therefore the reduction amount of the thickness compared to Vacuumed insulation panel, the shadow of the incrementss of area ratio to the intensity of heat insulating box
Sound is bigger, and box deformation amount is reduced, if but further increasing the configuration area ratio of Vacuumed insulation panel, the thickness of Vacuumed insulation panel
Degree becomes smaller, and the thickness of polyurethane becomes larger, thus the configuration area ratio of the incrementss of the thickness of polyurethane and Vacuumed insulation panel
Influence of the incrementss to the intensity of heat insulating box becomes on an equal basis, and the reduction degree of box deformation amount becomes smaller.
Therefore, if side/back side area ratio (side back face covering rate) of Vacuumed insulation panel 400 is set as predetermined value
(70%) more than, so that it may obtain cabinet intensity, therefore the cabinet of high reliablity can be obtained.In addition, if by Vacuumed insulation panel
Side/back side area ratio be set as predetermined value (70%) or more, then become box deformation amount hardly happen variation
Region, therefore even if the configuration area of Vacuumed insulation panel generates unevenness, the deflection of cabinet also hardly happens variation, therefore energy
Enough acquisitions are high-intensitive, aesthetic appearance is good, high reliablity heat insulating box, refrigerator, showcase, equipment.If making Vacuumed insulation panel 400
Covering rate is predetermined value or more (60% or more) and side/back side area ratio of Vacuumed insulation panel 400 is set as the 2nd
More than predetermined value (70%), then heat-proof quality improves, and can reduce box deformation amount, therefore can obtain heat-proof quality
Greatly, high reliablity and energy-efficient refrigerator, showcase, equipment.
Here, if fixing the thickness of Vacuumed insulation panel and expanding the configuration area of Vacuumed insulation panel 400, vacuum heat-insulation
The covering rate of part, filling rate can increase, if but the filling rate of Vacuumed insulation panel 400 increase, cost increases, therefore does not change
Become filling rate and cost is relatively low when by increasing intensity of the covering rate to improve heat insulating box 700, and can increase vacuum every
The configuration area of warmware, therefore heat-insulating efficiency improves.Therefore, by making 40% or more the filling rate of Vacuumed insulation panel 400, making
Side/back side area ratio (laterodorsal Vacuumed insulation panel covering rate) is 70% or more, can be with low-cost high-efficiency true
Protect the intensity of heat insulating box.Therefore, if by side/back side area ratio (laterodorsal Vacuumed insulation panel of Vacuumed insulation panel
Covering rate) be set as the 2nd predetermined value (be the reduction ratio of the deflection of heat insulating box become smaller area ratio, be, for example, 70%
Left and right) more than, so that it may the wall thickness (thickness that polyurethane is thinned) of heat insulating box 700 is thinned, increases the internal volume of storeroom.Side
The configuration area (laterodorsal Vacuumed insulation panel covering rate) of wall 790 and the Vacuumed insulation panel of back face wall 730 400 is bigger, heat-insulated
The deflection of cabinet 700 is smaller, therefore can increase the intensity of heat insulating box 700, and it is good can to provide high-intensitive and heat-proof quality
Heat insulating box 700, refrigerator 1, the equipment for having heat insulating box.
(polyurethane physical property)
Here, physical property, the characteristic to the hard polyurethane foams for being filled in heat insulating box 700 are illustrated.Hard polyurethane
Intensity stabilization, appearance good, quality high heat insulating box of the ester foam by increasing free foaming density, after foaming can be provided
700。
Here, free foaming density refers to, not makes polyurethane foam in the closed space such as cabinet but opening
Container in etc. hard polyurethane foams when making polyurethane foam under opening states density.And in fact, due to polyurethane
It foams, expand in closed narrow space in heat insulating box 700, therefore the narrow space closed in heat insulating box 700 etc.
The density of the polyurethane of interior foaming, expansion, the free foaming density of the polyurethane than foaming, expanding in the open state are big.
Density by improving the hard polyurethane foams after foaming can increase bending resistance springform as illustrated in figure 16
When measuring, but being filled to increase density to make polyurethane stock solution flow directly into heat insulating box 700, for the hair used now
The small polyurethane of multiplying power is steeped, free foaming density is small to 26~28kg/m3, expansion ratio is small, if therefore polyurethane flowing portion
Point flow path thickness that there are sizes is not, then foaming degree is uneven, and inlet 703,704 near and terminal part is (far from injecting
Mouthful position) polyurethane density is easy to produce unevenness, it is difficult to obtain stable intensity.
In the present embodiment, by using free foaming density than existing (for example, about 25~28kg/m3) big hard
Polyurethane foam (such as free foaming density is about 30~45kg/m3), even if the flow path thickness in the part of polyurethane flowing
It is not that there are a little sizes, also due to expansion ratio is big and can steadily foam, the unevenness of the density after can reduce foaming.
Thus, it is easy to keep the density of the polyurethane after foaming generally uniform.
Foaming body as hard polyurethane foams has bubble in inside, and density is smaller, and bubble is more, heat-insulated effect
Fruit is higher.Therefore, heat insulating box 700 makes the density after the foaming of the hard polyurethane foams used in the prior art
About 25~28kg/m3Small density hard polyurethane foams.Want to make bending resistance springform using the existing polyurethane foam
It is true removing when amount is intensity of the 15MPa or more to ensure heat insulating box 700, such as in the case where in wall with a thickness of 28mm
In the heat insulating box with a thickness of 8mm of polyurethane after the thickness of empty thermal insulator, it is necessary to inject, the lucky of packing ratio polyurethane is filled out
Charge (is gathering when will not apply unreasonable load etc. into the cabinet for becoming object and fill hard polyurethane foams just
Urethane amount, the density after foaming are easy to become uniform) polyurethane mostly, density is easy to produce unevenness.
In turn, the polyurethane due to that must inject, more than the lucky loading of packing ratio, it is therefore desirable to add in polyurethane injection
Pressure extends the filling time, so that polyurethane is from the gaps such as the joint portion of heat insulating box 700, the profile of shutter door (such as outer container
710 and interior case 750 joint portion) leak out, the polyurethane of the predetermined amount needed for can not injecting and (can not filling), it is difficult to ensure filling
The density of hard polyurethane foams after to cabinet is than predetermined value (such as 60Kg/m3) big density.In addition, if polyurethane from
The profile of cabinet leaks out, it is necessary to remove the operation of the polyurethane of leakage, activity duration or built-up time need to increase, cause
Cost increases, aesthetic appearance reduces.Therefore, the density for being filled into the polyurethane after heat insulating box in the prior art is less than 60Kg/m3,
About 25~30Kg/m3, up to about 55Kg/m3Below.
Here, in the present embodiment, have studied the amount by reducing foamed material for including in polyurethane stock solution etc. come
Increase free foaming density.Such as in polyurethane with a thickness of 8mm (the polyurethane flow path thickness after removing the thickness of Vacuumed insulation panel
Degree is about 8mm) heat insulating box 700 in, by the way that free foaming density is set as predetermined value (30kg/m3Above, preferably
35kg/m3More than), can make under lucky loading density (do not apply the ground such as unreasonable load be filled into it is poly- after cabinet
The density of urethane) compare 60kg/m3Greatly, the Deflection Modulus of Elasticity 15MPa or more of hard polyurethane foams can be made.Therefore, may be used
To eliminate the density unevenness of polyurethane, the heat insulating box that polyurethane leaks out etc the problem of, high reliablity, high intensity can be obtained
Heat insulating box 700, refrigerator 1, showcase, the equipment for having heat insulating box.
Here, worrying that the polyurethane increased after foaming because keeping the free foaming density of hard polyaminoester bigger than predetermined value is close
Influence to heat-proof quality is spent, but as illustrated by Figure 17~Figure 21, such as by the position that configures of Vacuumed insulation panel 400
The thickness of polyurethane is set as predetermined value or less (11mm or less or 6mm or less) or by thickness in thickness/wall of polyurethane
Be set as predetermined value (0.3) below or by the filling rate of Vacuumed insulation panel 400 be set as preset range (40% or more 90% with
Under) when, it can reduce the influence to the heat-proof quality of heat insulating box (to the heat-insulated of the heat insulating box of heat insulating box 700, shutter door
The influence of performance).In addition, make polyurethane with a thickness of 11mm or less when, by make free foaming density predetermined value (such as
35kg/m3) more than, it can be set to the lucky loading (adjustable lucky loading) for not causing polyurethane to leak out.
It is existing thin that the heat insulating box 700 of present embodiment can make the wall ratio of heat insulating box 700, furthermore it is ensured that in advance
Fixed intensity, in filling polyurethane, polyurethane is also difficult to leak out from profile, can satisfy required quality, can provide section
The heat insulating box 700 of energy, internal volume excellent in efficiency.That is, not changing heat insulating box 700 or refrigerator 1 or having heat insulating box
The outer dimension of equipment can just make the reserve of heat insulating box store volume (such as in the case where refrigerator for case internal volume or
Reservoir volume) it is bigger than existing, the storage item that the inside of heat insulating box 700 can store can be increased compared with prior art.Cause
This, can obtain that user is convenient to use, thermal insulation is good, high-intensitive and high reliablity heat insulating box 700 or refrigerator 1 or tool
The equipment of standby heat insulating box.In addition, by the storage volume settings of indoor (in storeroom) at it is same with the prior art when, can make
Outer dimension correspondingly reduces the amount that wall thickness can reduce.
Here, refrigerator 1 has for the cooling air supplied to multiple storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5
The cooling device of (cold air).The cooling device is (swollen by compressor 12, refrigerant piping (such as condensation piping 725), decompressor
Swollen valve, capillary etc.), cooler 13 etc. constitute, form refrigerating cycle.Constitute the compressor in the constituent element of the refrigerating cycle
12, decompressor is set to the machinery in back underside (the being also possible to back side upside) formation for the heat insulating box 700 for forming refrigerator 1
In the 1A of room.Such as side wall 790 or back face wall 730 or top wall 740 of the condensation piping 725 set on heat insulating box 700.Pass through
The fan grill etc. of reserve storage space is formed at the back side of storeroom, overleaf the storeroom side of wall 730 is equipped with and interior case
The back side cover of 750 seperated components, cooler 13 are cold set on being formed between the back sides cover member such as interior case 750 and fan grill
But in device room 131.In addition, being additionally provided in the cooler room 131 for blowing the air cooled by cooler 13 (cold air)
It is sent to the circulating cold air fan 14 of each storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5.In addition, 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 equipped with control base board room
31, control device 30 is equipped in control base board room 31, which carries out compressor 12 or circulating cold air fan 14
Revolving speed etc. motion control or the temperature inside the box control etc..
In the refrigerator 1 constituted in this way, by the gas system for the high temperature and pressure that the compressor 12 being configured in the 1A of Machine Room is sent out
Cryogen becomes the liquid refrigerant of cryogenic high pressure, low temperature in refrigerant piping (such as condensation piping) 725 by being condensed
The liquid refrigerant of high pressure is depressurized into the gas-liquid two-phase refrigerant of low-temp low-pressure by decompressor, when reaching cooler 13, is become
Such as -20 DEG C of low temperature below.Air in the cooling cooler room 131 of the gas-liquid two-phase refrigerant of the low-temp low-pressure, and should
Air after cooling is supplied to each storerooms such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5 by circulating cold air fan 14, thus
The storerooms (or the storage item stored in these storerooms) such as cooling refrigerating chamber 2, freezing chamber 6, vegetable compartment 5.On the other hand, cold
But the gas-liquid two-phase refrigerant of the low-temp low-pressure of the air in cooler room 131, by the air heating in cooler room 131
Evaporation, becomes the gas shape refrigerant of low pressure and is inhaled into compressor 12 once again and is compressed.
As described above, making Vacuumed insulation panel 400 relative in outer container 710 and interior case in the refrigerator 1 of present embodiment
Ratio, i.e. vacuum shared by total volume of the internal capacity of the door inner space in the space 315 and shutter door that are formed between 750
The filling rate of thermal insulator is predetermined value (such as 40%~80%).Therefore, even if thickness is (outside such as in the wall of heat insulating box 700
The thickness of distance (thickness) or shutter door between case 710 and interior case 750) it is thinner than the prior art, it can also ensure that thermal insulation
Energy.Therefore, in the refrigerator of present embodiment 1, the heat-proof quality of heat insulating box 700 is improved, thus multiple storerooms 2,
3, the cold air in 4,5,6, storage item are not easy to warm, therefore can shorten the duration of runs for cooling compressor 12 or subtract
The air quantity of small fan.Therefore, the air quantity of the required air (cold air) of the cooling in storeroom 2,3,4,5,6 can be inhibited compared with
It is small, the revolving speed of compressor 12 can be reduced or extend operating OFF time, therefore energy-saving operation can be carried out.Therefore, in this implementation
In the refrigerator 1 of mode, it can compare existing more energy saving.In addition, refrigerator 1 do not change outer dimension can be compared with prior art
Expand reservoir volume (case internal volume), can increase the storage item that can be stored in storeroom compared with prior art, therefore can be with
Obtain refrigerator convenient to use, equipment.
In addition, if the substantial middle position that up and down direction will be configured at the maximum freezing chamber 6 of the temperature difference of outer gas, it can
It is enough inhibit from above and under the heat from outer gas that enters towards freezing chamber 6, therefore heat can be made to invade freezing chamber 6 from outer gas
Hot entering surface is 4 faces (shutter door of front, left side, right side, this 4 face of the back side).Thus, it is possible to obtain energy-efficient refrigerator 1.
In addition, according to the present embodiment, making the bending resistance for being filled in the hard polyurethane foams in space 315 and door inner space
Elasticity modulus is 15.0MPa or more, therefore the cabinet intensity of heat insulating box 700 can satisfy scheduled intensity, so as to press down
Heat insulating box 700 processed is deformed because that can not be resistant to skew caused by the weight of storage item.Therefore, heat insulating box 700 can be inhibited
Skew and tilt the shutter door of front, the deterioration of appearance can be prevented.Furthermore, it is possible to inhibit to shutter door and heat insulating box
The position for the seal member being sealed between front openings portion is staggered and generates gap, to make refrigerating chamber 2, freezing chamber 6, vegetable
Dish room 5, ice-making compartment 3, the air (cold air) in switch room 4 to heat insulating box 700, refrigerator 1 external the case where leaking out, so as to
Enough obtain more energy efficient refrigerator, equipment.
It, can also be in addition, the distribution of the filling rate about the Vacuumed insulation panel 400 in space 315 or door inner space
According to the temperature difference of outer gas and each storeroom, and changed very in space 315 or door inner space according to scheduled position
The filling rate of empty thermal insulator 400.
For example, the freezing chamber 6 (or ice-making compartment 3, switch room 4) as low temperature chamber, stores indoor temperature and outer gas
Temperature difference it is maximum.Therefore, can make the left side of heat insulating box 700 in the range opposite with freezing chamber 6, right side,
The filling rate ratio of the Vacuumed insulation panel 400 of the back side and front (shutter door) and other storerooms (such as the refrigeration as hot room
Room 2, vegetable compartment 5) opposite range wall surface (such as left side, right side, the back side and front (shutter door)) it is big by (such as 60%
More than).With this configuration, it is able to suppress the heat intrusion to the i.e. freezing chamber 6 of the minimum low temperature chamber of temperature, can be obtained more energy efficient
Refrigerator 1, equipment.
For example, becoming such as 40 DEG C or more in the 1A of Machine Room, the temperature of control base board room 31 when outside air temperature is such as 30 DEG C
Degree also rises to such as 40 DEG C or more.That is, the wall between Machine Room 1A and control base board room 31 and the storeroom of opposite position
Face, partition wall 24, wall surface, partition wall 24 compared to other parts, indoor temperature difference is larger with storing.Therefore, heat is easy to invade
Enter the storeroom configured near Machine Room 1A, control base board room 31.Therefore, Machine Room 1A or control base board room are being configured at
Wall surface, partition wall 24 between 31 and storeroom, can make the filling rate of Vacuumed insulation panel 400 than other wall surfaces, partition wall 24
It is big to improve heat-proof quality.Such as in wall surface, the partition wall being configured between Machine Room 1A or control base board room 31 and storeroom
