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) Small, therefore, heat-proof quality deteriorates.Here, in the case where increasing the width of Vacuumed insulation panel to improve heat-proof quality, if 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 supports the ballast support component of the support weight such as track component or door frame of box body or generates the cold air for cooling down storeroom Cooler or influenced component etc. by the vibration that is influenced is vibrated when operating to fan of storeroom blowing cooling air etc.) when, peace The position of dress is required to obtain the wall thickness of installation strength, in addition, according to the relationship of the installation strength of screw, the fixed parts such as screw The length of the threaded portion of part is also difficult for predetermined length (such as 15mm) hereinafter, therefore, it is difficult to reduce wall thickness, it is difficult to increase content Product.

The present invention is to complete to solve the above-mentioned problems, main purpose be to ensure that heat insulating box heat-proof quality and Intensity.In addition, there are also obtain heat insulating box, refrigerator, the water storage that can be realized the slimming of thermal wall or thermal insulator for its purpose Device, equipment with high-temperature portion or low temperature portion etc..

In Fig. 4, the heat insulating box 700 for constituting refrigerator 1 is made of outer container 710 and interior case 750, in outer container 710 and interior case Vacuumed insulation panel 400 is configured between 750.Vacuumed insulation panel 400 is set to the back side of refrigerator 1, makees via hot melt adhesive, double-sided adhesive etc. The 2nd bonding agent for the 2nd sandwiched component is adhered directly onto outer container 710.In addition, Vacuumed insulation panel 400 is directly viscous by bonding agent It is attached to a part (such as the left and right directions substantially central portion for forming the wall surface at interior 750 back side of case) of interior case 750, in addition to interior case Left and right end portions (corner part) near side wall 790 except the substantially central portion at 750 back sides are formed with compared with back face wall 730 preceding Surface side protrusion 450 outstanding, Vacuumed insulation panel 400 are configured to predetermined length Chong Die with the protrusion 450, but can also in protrusion 450 There is the position for not configuring Vacuumed insulation panel 400 and being only filled with polyurethane.In addition, interior case 750 and Vacuumed insulation panel 400 it Between filled with as the 1st sandwiched component bonding agent (can be used such as hard polyaminoester have self-adhesiveness foaming every Warmware), Vacuumed insulation panel 400 is set to interior 750 He of case via the bonding agent (such as hard polyaminoester etc.) as the 1st sandwiched component Between outer container 710.Therefore, Vacuumed insulation panel 400 by the 1st sandwiched component and the 2nd sandwiched adhering components or cementation or is fixed to Interior case 750 or outer container 710.

Here, the back side shape of interior case 750 when being seen from the front side of refrigerator 1 (storeroom side), formed above and below substantially The recess portion 440 (also referred to as the 1st recess portion) of the groove-like of central portion recess.In the recess portion 440 that the substantially central portion is formed, vacuum Thermal insulator 400 is adhered directly onto outer container 710 and interior case 750 via bonding agent.In addition, from the front side (storeroom side) of refrigerator 1 When seeing, the back side shape of interior case 750 becomes width direction (left and right directions) end side substantially compared to width direction (left and right directions) Central portion forwardly opening portion side (storeroom side) convex form outstanding.In other words, the back side shape of interior case 750 has right and left To substantially central portion compare the lateral outer container side of left and right end portions (rear side of refrigerator) be recessed groove-like, that is, recess portion 440, this is recessed Portion 440 is set to the up and down direction of refrigerator in storeroom (such as refrigerating chamber 2).

That is, recess portion 440 is formed by the side 452 of protrusion 450 and back face wall 730, in the inner face for forming back face wall 730 The Vacuumed insulation panel of plate is provided between the outer container 710 of the outside of the interior case 750 and formation back face wall 730 of (storeroom side) 400.Here, although it is not shown, but in the interior case 750 for forming the inner face (storeroom side) of side wall 790 and side wall can also be formed The Vacuumed insulation panel 400 of plate is set between the outer container 710 of 790 outside.Set on back face wall 730 or the cold air of recess portion 440 Wind path 760, by with aesthetic appearance as the 1st wind path accessory 762 of cover member and set on the back side of the 1st wind path accessory 762 Side (interior 750 side of case) simultaneously there is the 2nd wind path accessory 764 of thermal insulation to constitute, and be configured in recess portion 440.This is as cover member Perhaps there is the 2nd wind path accessory 764 1st wind path accessory 762 mounting portion (holding section) to be embedded into set on protrusion 450 or the back side The mounting portion (holding section) of wall 730 or engage with each other mounting portion by fixation members such as screws, thus by cover member 760 are installed to protrusion 450 or back face wall 730.

At the protrusion 450 for the left and right end portions side for being formed in the back side in the storeroom, center side (the overlapping length of width direction Spend the range of X), Vacuumed insulation panel 400 is configured between outer container 710 and interior case 750, between Vacuumed insulation panel 400 and interior case 750 Filled with the bonding agent (for the foaming heat insulation part 701 of self-adhesiveness, such as hard polyaminoester) as the 1st sandwiched component, in addition, Pass through the 2nd bonding agent bonding as the 2nd sandwiched component between outer container 710 and Vacuumed insulation panel 400.The width side of protrusion 450 To end side between outer container 710 and interior case 750 stuffed heat insulated part 701 (such as hard polyaminoester), there are not set vacuum The part of thermal insulator 400.Certainly, at protrusion 450, increase Vacuumed insulation panel 400 in width direction to increase width direction Heat-proof quality and cabinet intensity can be improved in the configuration area of Vacuumed insulation panel 400, but cost increases, if therefore heat-proof quality It is predetermined value or more with intensity, then can sets the part of not set Vacuumed insulation panel 400.

Here, Vacuumed insulation panel 400 and outer container 710 are via the 2nd bonding agent as the 2nd sandwiched component in recess portion 440 It directly pastes, Vacuumed insulation panel 400 has self-adhesiveness and hair via the polyurethane etc. as the 1st sandwiched component with interior case 750 The bonding agent of bubble property is pasted.(for example filled with the hard polyurethane as bonding agent between Vacuumed insulation panel 400 and interior case 750 Ester foam.)

Therefore, in the heat insulating box or refrigerator for having Vacuumed insulation panel, with such as prior art (such as patent document 2) that Sample the storeroom back side width direction the configuration section of Vacuumed insulation panel be not provided with polyurethane etc. with it is heat-insulated as the main purpose Thermal insulator 701 and compared in the case where directly setting Vacuumed insulation panel 400 of interior case 750, in the present embodiment at left and right end Portion side (width direction end side) forms the protrusion 450 being made of the thermal insulators such as polyurethane 701 along the vertical direction, therefore passes through shape At the protrusion 450, torsional strength, the buckling strength of cabinet can be improved.In the structure shown in patent document 2, in storeroom The width direction at the back side part Chong Die with the configuration section of Vacuumed insulation panel 400 there is no protrusion 450, therefore reversed in cabinet When, protrusion 450 and Vacuumed insulation panel 400 disconnect, and may generate the worry of intensity decline, cabinet breakage.Here, vacuum heat-insulation The side portion (the only part of outsourcing material) of part does not have core material, therefore does not have heat insulating function, and furthermore intensity is also weak, therefore right In the side portion of Vacuumed insulation panel, excluded from the composition accessory of Vacuumed insulation panel.

Here, as shown in the embodiment, the width direction at the storeroom back side, protrusion 450 be configured to and vacuum every When the configuration section of warmware 400 is at least locally overlapped (when being arranged to overlap length X overlapping), it is filled into the inside of protrusion 450 Hard polyurethane foams be also filled into Vacuumed insulation panel 400 width direction (left and right directions) end side vacuum heat-insulation A part between part 400 and interior case 750, therefore the Vacuumed insulation panel 400 for being filled into the position opposite with protrusion 450 can be made The thickness of hard polyurethane foams between interior case 750, the Vacuumed insulation panel of the position opposite with recess portion 440 than being filled into 400 and interior case 750 hard polyurethane foams thickness it is big, so, can increase hard polyurethane foams relative to vacuum every The bond area of warmware 400, and the thickness of the hard polyurethane foams of 400 part of Vacuumed insulation panel can be increased, therefore convex The bond strength of hard polyurethane foams and Vacuumed insulation panel 400 in portion 450 increases.

Therefore, even if hard polyurethane foams between the Vacuumed insulation panel 400 and interior case 750 that are thinned at recess portion 440 Thickness can also greatly improve protrusion 450 and Vacuumed insulation panel 400 and protrusion 450 and side wall 790 (or setting protrusion 450 Surrounding wall) bond strength, greatly improve the intensity of cabinet.In addition, being capable of increasing hard polyurethane foams in protrusion 450 Thickness, therefore even if there are the part of not set Vacuumed insulation panel 400, heat-proof quality is also improved.

In addition, in embodiments of the present invention, not needing as existing patent document 2 in order to ensure cabinet intensity And Vacuumed insulation panel, interior case, outer container are shaped to complicated shape, in addition, the core material of Vacuumed insulation panel be able to use at a low price and The core material (cotton like core material, non-woven fabrics core material etc.) of the good organic fiber of heat-proof quality, inorfil, thus can obtain it is low at Sheet, the heat insulating box that structure is simple and heat-proof quality is high, refrigerator, showcase, hot water supply device, the equipment for having Vacuumed insulation panel Deng.

It therefore, is not in following situation: for example, box back surface is deformed and formed in storeroom concave-convex；In addition, example Make to be set to door of storage room (such as refrigerating-chamber door 7) inclination before storeroom (such as refrigerating chamber 2) such as box deformation；This Outside, one side of the door (7A, 7B) of left and right tilts and causes to misplace in the case where such as clamshell doors.Therefore, can successfully into The opening and closing of row door of storage room, in addition, the dislocation of the door of storage room of left and right will not be caused, therefore beautiful (aesthetic appearance is good).In addition, not Can cause because of box deformation storeroom (such as ice-making compartment 3, switch room 4, vegetable compartment 5, freezing chamber 6 etc.) inner wall or left and right Shutter door, the mounting height of track component of drawer type box body or so of side wall setting be different or inclination, therefore can be smooth Ground carries out the discrepancy of box body, obtains high reliablity, refrigerator easy to use, equipment.

In addition, the shape when Vacuumed insulation panel 400 is tabular, at the back side that Vacuumed insulation panel 400 is equipped on to refrigerator 1 Under state, (width direction) or front-rear direction are easy bending and are easy torsion in left and right directions, about this point, are being equipped on refrigerator Etc. in the state of equipment, if left and right end portions side overleaf forms the protrusion 450 for being equipped with the thermal insulators such as polyurethane in above-below direction And Vacuumed insulation panel 400 is integrally formed with the polyurethane being filled in protrusion 450, then in case 750, Vacuumed insulation panel 400, outer Case 710 is bonded by the one of protrusion 450, therefore can improve the buckling strength of cabinet 700 (bending especially forward and backward is strong Degree), torsional strength.Therefore, the opening portion deflection deformation of the storeroom of front openings or the sealing because of opening portion are able to suppress Dislocation of part etc. and the problem of cause cooling gas leakage, thus obtain high reliablity, high-performance and energy-efficient heat insulating box, refrigerator, The equipment for having Vacuumed insulation panel.

In addition, having and being arranged with heat-insulated polyurethane etc. as the main purpose between interior case 750 and Vacuumed insulation panel 400 The position (protrusion 450) of foaming heat insulation part and setting be not with heat-insulated bonding agent as the main purpose (such as due to heat-insulated As the main purpose and be bonded as the main purpose, as long as therefore have self-adhesiveness, can be polyurethane etc.) position (recess portion 440), therefore, setting be bonded bonding agent as the main purpose position (recess portion 440) and setting with it is heat-insulated be main The position of the thermal insulators such as the polyurethane of purpose is compared, without the predetermined thickness as the thermal insulator for obtaining heat-proof quality, only There is scheduled adhesive strength.Therefore can make to glue to be bonded the position (such as recess portion 440) used as the main purpose The thickness for connecing agent is fairly small.When therefore using hard polyaminoester as bonding agent, compared to the heat-insulated portion used as the main purpose Position, can make the thickness of polyurethane fairly small.Therefore, the amount of the thickness difference of wall thickness reduction bonding agent can be made, so as to increase The internal volume of big storeroom obtains refrigerator easy to use, equipment.

Here, the lead storage member of the leads such as driving power line of storage control wiring, compressor and fan etc. is Pipe 720 is embedded in above-below direction in the thermal insulators such as the polyurethane to form protrusion 450 701.In the pipe 720 storage for into The control wiring of the operating control of open and close control, compressor 12 and the circulating cold air fan 14 of the various air doors of row etc. etc. is used for The leads such as the power line supplied electric power to compressor 12 and circulating cold air fan 14 etc..The leads such as control wiring, power line exist Pass through in pipe 720 and connect with such as lower component: the compression configured in the Machine Room 1A of lower part (or top) for being set to refrigerator 1 Machine 12；Set on the back side of refrigerator 1, bottom surface or control device (control base board etc.) 30 above；Set on the cold of cooler room 131 etc. Gas circulation air fan 14；Switch room air door 15, refrigerator damper 55 set on cold air wind path；(such as cold to cover storeroom Hiding room 2) before the operation panel 60 etc. of shutter door (such as refrigerating-chamber door 7) setting that is arranged of mode.

It is less than the storage of the side wall 790 of refrigerator 1 set on the width of the left and right directions of the Vacuumed insulation panel 400 at the back side of refrigerator 1 The indoor width faced the wall and meditated between 791,792 in hiding will not be blocked in the polyurethane etc. of the end setting of the left and right directions at the back side of refrigerator 1 Multiple charging ports (inlet) 703,704 of thermal insulator will not block the thermal insulators such as the polyurethane filled from charging port 703,704 Filling flow path.

Here, the width for being set to the left and right directions of the Vacuumed insulation panel 400 at 1 back side of refrigerator is worked as and the side wall 790 of refrigerator 1 The width (distance) of (storeroom is left inside to face the wall and meditate between 791 and the right inner surface 792 of storeroom) is identical between storeroom inner surface or compares Its hour, will not block the thermal insulators such as polyurethane charging port or filling flow path, thus polyurethane thermal insulator without interruption by The decline etc. of heat-proof quality will not occur for filling, therefore preferably.But as long as Vacuumed insulation panel 400 is configured in and is set to refrigerator 1 The charging port 703,704 of thermal insulators such as the polyurethane of left and right end portions of back side allocation position it is identical or than charging port 703, 704 are close to the position of central side (interior direction), and the charging port 703,704 of polyurethane thermal insulator would not be by Vacuumed insulation panel 400 block, therefore will not interfere the thermal insulators such as the polyurethane filled from charging port 703,704 in side wall 790 or protrusion In 450 or it is equal between Vacuumed insulation panel 400 and interior case 750 flow (being filled), it is bad etc. to occur filling polyurethane, Heat-proof quality will not decline.

Here, Vacuumed insulation panel 400 and interior case 750 (can be with certainly via with the bonding agent of bonding as the main purpose The foaming heat insulation part of cementability) the direct bonding site i.e. recess portion 440 that is directly bonded, relative to being filled with such as hard polyaminoester The strengthening part sandwiched position (such as protrusion 450) of equal strengthening parts has the stage portion 776 of the projecting height amount of protrusion 450, Recess portion 440 is recessed relative to protrusion 450 to depth direction (rear side).Conversely, the protrusion 450 as strengthening part sandwiched position It is prominent to the front side of depth direction relative to the recess portion 440 as direct bonding site using the amount of stage portion 776.In addition, true The direct bonding site that empty thermal insulator 400 and interior case 750 are directly bonded via bonding agents such as the foaming heat insulation parts of self-adhesiveness is i.e. Recess portion 440, the step that the height (thickness) with cold air wind path 760 is measured, front side of the recess portion 440 relative to cold air wind path 760 End 769 is recessed to depth direction (rear side).Conversely, before cold air wind path 760 side end face 769 with the amount of step relative to Direct bonding site is prominent to the front side of depth direction.

As described above, in the present embodiment, formed by interior case 750 and outer container 710 and in interior case 750 and outer container 710 Between have in the equipment such as heat insulating box, refrigerator, cold insulated cabinet, the showcase of Vacuumed insulation panel 400, have: indoor (example will be set to In such as storeroom) back face wall 730 in Vacuumed insulation panel 400 it is straight by the foaming heat insulation part bonding agent with self-adhesiveness Connect the direct bonding site (being recess portion 440 in figure) for pasting interior case 750；And between Vacuumed insulation panel 400 and interior case 750 The strengthening part sandwiched position that sandwiched is used to improve the thermal insulators such as the polyurethane as strengthening part of intensity of cabinet (is in figure Protrusion 450).Here, Vacuumed insulation panel 400 and outer container 710 are affixed directly to one by the 2nd bonding agent such as hot melt adhesive, double-sided adhesive It rises.2nd bonding agent such as hot melt adhesive, double-sided adhesive can be pre-coated with or be pasted onto 710 side of 400 side of Vacuumed insulation panel or outer container, Therefore the thickness of bonding agent can be thinned, thus it is preferred that；But it may generate that coating is uneven, it is unequal to paste, therefore vacuum It is preferable to use the foaming heat insulation parts with self-adhesiveness between thermal insulator 400 and interior case 750.

In addition, in the present embodiment, such as strengthening part sandwiched position (such as protrusion 450) and direct bonding site (such as recess portion 440) is arranged in the width direction for storing indoor sustained height position, by storing indoor width direction Left and right end portions setting strengthening part sandwiched position (such as protrusion 450) and clipped with the strengthening part sandwiched position controlled Mode be set to left and right strengthening part sandwiched position between direct bonding site (such as recess portion 440), and storeroom carry on the back The left and right directions in face forms protrusion 450 (strengthening part sandwiched position), and (the direct adhesive portion of recess portion 440 is formed between protrusion 450 Position).Here, recess portion 440 and protrusion 450 are from the intensity for ensuring cabinet or ensure the angle of cold air wind path, preferably storing up Hide the substantially entire altitude range setting of indoor up and down direction.

So, in the position opposite with recess portion 440, make Vacuumed insulation panel 400 and outer container 710 via the 2nd bonding agent It directly contacts or abuts, therefore do not need thermal insulator between outer container 710 and Vacuumed insulation panel 400, when with sandwiched thermal insulator Compared to storage chamber volume can be increased.In addition, at direct bonding site (such as recess portion 440), make Vacuumed insulation panel 400 and interior Case 750 is contacted or is abutted via the foaming binding agent with cementability.In the present embodiment, in Vacuumed insulation panel 400 It configures position (such as recess portion 440), there is heat-proof quality and intensity by Vacuumed insulation panel 400, therefore in interior case 750 and very It 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 discontinuously 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).

Also it can use and exist relative to the partition wall for the storeroom (above or below or side) for being equipped with mist device 200 It is cooled down with the cold air in another adjacent storeroom (such as freezing chamber 6) of storeroom (such as vegetable compartment 5) opposite side setting Radiating part.At this point, by radiating part be arranged to from the underside wall of storeroom side and other storerooms (such as freezing chamber) or above Wall contact.Mist device 200 can be set to any storeroom as storeroom, can in refrigerating chamber 2 or vegetable compartment 5 or In any storeroom such as person chilled room 2X, 2Y or container.When mist device 200 is set to back face wall, it can be set to and be formed in storage The partition wall of a part for the back face wall being arranged between room and cooler room.It (also can be set into two with temperature difference Between adjacent storeroom (such as high temperature side storeroom, that is, vegetable compartment 5 and adjacent low temperature side storeroom, that is, freezing chamber 6 it Between) demarcation plate on high temperature side storeroom side be arranged mist device 200, by one end of radiating part (with discharge electrode opposite side End) be arranged to contact with the demarcation plate of other storerooms, using the low temperature of the storeroom of low temperature side cold air (utilize high temperature The temperature difference of the storeroom of the storeroom and low temperature side of side) cool down radiating part.)

As shown in Figure 10, Vacuumed insulation panel 400 is set to the back side of refrigerator 1, above, bottom surface.Although in addition, do not illustrate, But Vacuumed insulation panel 400 also is provided in side, partition wall 24, door.Set on the back side Vacuumed insulation panel 400 as illustrated in figure 8 As, at least in the range of recess portion 440, directly glued by the foaming heat insulation part as bonding agent that main purpose is bonding It is attached to outer container 710, interior case 750, the hard polyurethane foams with cementability is used as bonding agent, uses hard polyurethane When ester foam, by suitably adjusting free foaming density, narrow flow path (such as Vacuumed insulation panel 400 and interior case 750 it Between etc.) in can also equably be filled.Further, since can also be bonded in narrow flow path, therefore suitable as bonding agent With hard polyurethane foams, used hard polyurethane foams as bonding agent.

When main purpose uses hard polyurethane foams as bonding agent, the thickness because of hard polyurethane foams can not be considered Spend it is thinning caused by heat-proof quality reduction, therefore can make hard polyurethane foams with a thickness of scheduled thickness hereinafter, The thickness of wall surface (such as back face wall) can be thinned, the indoor volume of storage can be increased.Hard polyurethane foams are used as viscous Predetermined thickness when connecing agent as bonding agent can be about 11mm or less (e.g. preferably smaller than 10mm), even more preferably about 6mm with Under, it is predetermined thickness (such as 1mm in addition, the more Bao Yuehao as long as it can satisfy as the bonding force (adhesive property) of bonding agent Above, it is preferably 3mm) above degree is advisable.Such as when thinner than 1mm, the thickness of bonding agent can not absorb Vacuumed insulation panel 400 The roughness (bumps of outsourcing material) on surface, generate Vacuumed insulation panel 400 surface protrusion directly contacted with interior case 750 and The part that can not be bonded may reduce adhesive strength, therefore using hard polyurethane foams as bonding agent in use, if excessively thin Then adhesive strength is likely to decrease, therefore preferably more than predetermined thickness.

Certainly, using hard polyurethane foams as bonding agent in use, not cannot get heat-proof quality, although than vacuum every Warmware 400 is poor, but can also obtain the heat-proof quality as thermal insulator.That is, Vacuumed insulation panel 400 is adhered to such as outer container 710 or when interior case 750, if as bonding agent using hard polyurethane foams, in addition to obtaining based on Vacuumed insulation panel 400 Except heat insulation, the heat insulation based on polyurethane can also be obtained.In addition, between interior case 750 and outer container 710 not The part of Vacuumed insulation panel 400 is set, the thickness of hard polyurethane foams can be made to increase not set Vacuumed insulation panel 400 Amount, therefore heat-proof quality is improved.Furthermore, it is possible to using the hard polyurethane foams with self-adhesiveness as interior 750 He of case Bonding agent between outer container 710 uses.Therefore, the cabinet intensity of heat insulating box 700 improves, in addition, heat-proof quality also improves.

The cold air generated by the cooler 13 being configured in cooler room 131, by circulating cold air with fan 14 via cold Gas wind path 16, as air quantity adjustment member refrigerator damper 55, be formed in the refrigerating chamber cold air wind path of the 2nd wind path accessory 760 from be set to the 1st wind path accessory 762 cool-air feed mouth 768 be fed into refrigerating chamber 2 (including substantially closed container 2X, 2Y).Wind path 410 is returned by refrigerating chamber to the cold air cooled down in the refrigerating chamber 2 as storeroom and returns to cooler room 131, but a part that refrigerating chamber returns to the cold air in wind path 410 can also be supplied to vegetable compartment 5.At this point, in vegetable compartment 5 The cold air cooled down returns to wind path 430 by vegetable compartment and returns to cooler room 131.About the cold air to vegetable compartment 5 Supply, can use to other storerooms such as refrigerating chamber 2, switch room 4 carried out cooling and return cold air that temperature rises into Row cooling, but it is directly cooling also to can use the cold air generated by the cooler 13 of cooler room 131.

The cold air of ice-making compartment 3 or switch room 4 is gone to by the movement of circulating cold air fan 14 from being configured at cooler Cooler 13 in room 131 is via cold air wind path 16, the switch room air door 15 as quantity regulating device for air, switch room cold air wind Road 17 is supplied to, and (not shown) back to cold with wind path is returned with wind path (not shown) or switch room is returned via ice-making compartment But device room 131.The cold air of freezing chamber 6 is gone to from the cooler 13 being configured in cooler room 131 via cold air wind path 16, freezing Room cold air wind path 18 is supplied to, and returns to cooler room 131 with wind path 420 is returned via freezing chamber.

Here, the supply of the mist to storeroom, it can be simultaneously or wrong with opening or closing for circulating cold air fan 14 ETAD expected time of arrival and departure is linkedly powered or stops to mist device 200.In addition, when mist is supplied to multiple storerooms, the 1st storeroom The mist of (such as vegetable compartment 5, refrigerating chamber 2) and the 2nd storeroom (such as refrigerating chamber 2, freezing chamber 6, vegetable compartment 5, switch room 4 etc.) supplies Throttle setting (such as switch room air door 15, refrigerator damper 55, vegetable compartment air door, freezer damper can be used in the switching given Deng).For example, mist device 200 is configured to the separation that its at least part is accommodated in the top of the 1st storeroom (such as vegetable compartment) When the recess portion of wall, in the case that there is the wind path for the mist supply being connected to the recess portion in partition wall, vegetable compartment air door is beaten When opening, via the 1st cold air wind path, (such as vegetable compartment returns to wind path by the wind path of the mist supply in partition wall for mist in recess portion Deng), cooler room, the 2nd cold air wind path be fed into the 2nd storeroom (such as refrigerating chamber), when vegetable compartment air door is closed, not to Vegetable compartment cool-air feed, therefore the mist in recess portion is fed into the 1st storeroom (such as vegetable compartment) by gravity.This When, it can be using the 2nd cold air wind path as the cold air wind path 760 for being set to 2 back side of refrigerating chamber.Furthermore, it is possible to pass through throttle setting It is opened and closed to switch the supply of the supply to the mist of the 1st storeroom and the mist to the 2nd storeroom.In addition it is also possible to be filled instead of air door It sets, and is carried out by the circulating cold air opening of fan 14, closing.

Furthermore, it is possible to will be mixed in recess portion with cold air and the cool-air feed comprising mist is supplied to the 1st to the 1st storeroom A part of the cold air comprising mist of storeroom is via the wind path for being set to partition wall (such as partition wall, lateral separation wall above) (such as return wind path towards cooler room) returns to cooler room, and includes to the supply of the 2nd storeroom via cooler room The cold air of mist.Wind path set on partition wall can be by least part or whole will store mist device 200 (atomising device) The cover that is arranged of mode of recess portion covering formed, can also be formed by another accessory, the inside of partition wall can also be set to.? This, is arranged cold air inlet, cold air outlet at least one on cover.

(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 Outer container 710 or control base board room 31 are used as bonding agent by rigid polyurethane foam between Vacuumed insulation panel 400 and interior case 750 Foam, which is set in predetermined thickness (such as 1mm or more preferably 3mm or more and 11mm or less preferably 6mm or less) and is filled, to be advisable.

In addition, in the present embodiment, being configured to control base board room 31 being set to the upper surface of refrigerator 1 and using Vacuumed insulation panel 400 by surrounding insulation, and when the semiconductor fittings such as inverting driving circuit accessory use wide bandgap semiconductor, even if control base board room It is covered and is made in control base board room 31 under hot environment with Vacuumed insulation panel 400 or polyurethane thermal 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 freedom degree (freedom degree of design) of the setting of substrate room 31 improves, and can obtain the sky that can be efficiently used in such as Machine Room 1A Between the equipment such as refrigerator, air conditioner.

(defrosting heater, defrosted water utilization)

Compressor 12 is configured in the Machine Room 1A for being set to the back side lowest part (or back side topmost) of refrigerator 1.Refrigerator 1 With refrigerating cycle, compressor 12 is an accessory for constituting refrigerating cycle, is configured at Machine Room 1A, has compression refrigerating cycle The effect of interior refrigerant.The refrigerant compressed by compressor 12 is condensed in condenser (not shown).The shape being condensed The refrigerant of state as decompressor capillary (not shown), be depressurized in expansion valve (not shown).Cooler 13 is structure At an accessory of the refrigerating cycle of refrigerator, it is configured at cooler room 131.By the refrigerant of decompressor decompression in cooler 13 The gas of middle evaporation, heat-absorbing action when by the evaporation, 13 periphery of cooler is cooled.Circulating cold air is with fan 14 in cooling It is configured in device room 131 near cooler 13, the cold air for will be cooled on 13 periphery of cooler is via cold air wind path (example Such as switch room cold air wind path 16, refrigerating chamber cold air wind path 50) be blown into refrigerator 1 as storeroom each room (refrigerating chamber 2, Ice-making compartment 3, switch room 4, vegetable compartment 5, freezing chamber 6).

The conduct defrosting structure for the defrosting for carrying out cooler 13 is equipped in the lower section for the cooler 13 being set in cooler room 131 (Glass tube heater of defrosting has e.g. been used and has been issued in quartz glass tube through stone the defrosting heater 150 of part The carbon heater etc. of the carbon fiber of 0.2 μm~4 μm of wavelength of light of English glass tube).In cooler 13 and defrosting heater 150 Between, the top of defrosting heater 150 be equipped with heater top cover 151, to prevent the defrosted water fallen from cooler 13 straight It connects and falls on defrosting heater 150.It, can be with if heater of the defrosting heater 150 using the black medium such as carbon heater Effectively melt the frost of cooler 13 by radiant heat transfer, therefore surface temperature low temperature (about 70 DEG C~80 DEG C) can be made, When the refrigerant for refrigerating cycle uses combustible refrigerant (such as iso-butane as hydrocarbon refrigerant etc.), The risk of kindling can also be reduced even if refrigerant leakage etc. occurs.In addition, spoke can be passed through compared with nichrome wire heater Penetrate heat transfer and effectively melt the frost of cooler 13, therefore the frost tied in cooler 13 gradually melts, frost be difficult to it is blocking and thump It falls, therefore can reduce and fall sound when falling on heater top cover 151, be capable of providing low noise and the good ice of defrosting efficiency Case.

Here, defrosting heater 150 can be the heater for being integrally assembled into the embedded type of cooler 13.In addition, Glass tubular type heater and embedded type heater can be used together.The defrosted water that is generated by cooler 13 falls on heater top cover 151 defrosted water is fallen in cooler room and via the defrosted water carrier 154 being set to below cooler room 131 from defrosting Water outlet 155 is discharged to outside refrigerator (such as evaporating pan etc. set on Machine Room 1A).

Here, when being equipped with freezing chamber cooler and refrigerating chamber the two cooler (evaporators) of cooler, cold Hide room cooler in, evaporating temperature can be set to compared with cooler with freezing chamber it is relatively high, to be attached to cooling The frost of device is less.It therefore, there is no need to defrosting heater 150, to also not need heater top cover 151.Therefore, by cooler 13 generate defrosted water fallen directly in cooler room set on the lower part of cooler room 131 defrosted water carrier 154 and from Defrosted water outlet 155 is discharged to outside refrigerator (such as evaporating pan etc. set on Machine Room 1A).

When being equipped with freezing chamber cooler and refrigerating chamber the two cooler (evaporators) of cooler, in refrigerating chamber 2 Lower part (substantially closed container 2X, 2Y) rear the storeroom back side or vegetable compartment 5 the back side setting refrigerating chamber cooling Device, therefore mist device 200 is set to the back face wall or substantially closed container 2X, 2Y of the reserve storage space of refrigerating chamber 2 The storeroom back face wall or the back face wall of vegetable compartment 5 at the rear at the back side etc..Water supply member as mist device 200 can To use the defrosted water generated by refrigerating chamber cooler, and substitutes and be configured in cooler room 131 under cooler 13 The heater top cover 151 of side and configure the container for accepting the defrosted water generated by refrigerating chamber cooler and retention.At this point, When water is overflowed from the water outlet container on the top for being set to container, if being discharged to the water overflowed from defrosted water outlet 155 Outside refrigerator, then do not need to handle the water overflowed from the water outlet for being set to upper vessel portion.Therefore, container is set to cooler room In 131, container is set to the lower section of refrigerating chamber cooler and the top of defrosted water outlet 155 is advisable.In addition, if mist fills The discharge electrode for setting 200 is set to the top position of container and with the position of refrigerating chamber cooler equal height (before cooler Surface side position) or refrigerating chamber cooler and container between position, then by the water in container by capillarity etc. The feed path of water can be shortened when being supplied to discharge electrode, therefore preferably.

Mist device 200 can be configured to its at least part and be accommodated in set the lower section of freezing chamber 6 is adjacent as shown in the figure In the recess portion of the upper surface of the vegetable compartment 5 set wall (partition wall 24 above), the storeroom (vegetables with setting mist device 200 are utilized Room 5) other storerooms (freezing chamber 6) for being disposed adjacent of top in cold air, so that radiating part is generated dew, and use the knot Dew applies voltage to discharge electrode, and discharge electrode is made to generate mist.

In Fig. 9, Tu10Zhong, interior illuminator 900 is stored set on the top for example as the inner wall of the refrigerating chamber of storeroom 2 Wall (upper wall) 740, is made of multiple LED.Indoor side wall 790, bottom are stored here, lighting device 900 can also be set to It faces the wall and meditates 780, partition wall 24.Multiple LED of lighting device 900 are set to the front side of refrigerator 1 compared to the leading edge of shelf 80, can be with It will not equably be irradiated in storeroom from top to lower section with being covered by shelf 80.In addition, in multiple LED of lighting device 900 At least one can be irradiated when opening door of storage room (such as refrigerating-chamber door 7) set on door of storage room (such as refrigerating-chamber door 7) mode of door storage portion configures optical axis, thus it is dim around the refrigerators such as night 1 when, can not only irradiate in storeroom, A storage portion can also be irradiated, therefore the refrigerator that user is easy to use can be obtained.

In 710 side of outer container (opposite side with storeroom side) of the orbit portion 755 of interior case 750, with Vacuumed insulation panel 400 Between be equipped with strengthening part 731, between strengthening part 731 and Vacuumed insulation panel 400 as the 3rd sandwiched component be filled with poly- ammonia The thermal insulators such as ester 701, strengthening part 731 are fixed or are held in a manner of being close to substantially the thermal insulators such as polyurethane 701 Orbit portion 755.Between the orbit portion 755 and outer container 710 of interior case 750, orbit portion 755, reinforcement part are successively arranged from interior 750 side of case The thermal insulators such as part 731, polyurethane 701, Vacuumed insulation panel 400, outer container 710.Here, in the present embodiment, in interior 750 He of case The thermal insulators such as filled polyurethane 701 between Vacuumed insulation panel 400, heat-proof quality and cabinet intensity are mentioned by Vacuumed insulation panel 400 For, therefore thermal insulator 701 can also be substituted and bonding agent is used to can be used at this time as bonding agent as the 3rd sandwiched component Hard polyurethane foams as the foaming heat insulation part with self-adhesiveness.In addition, outer container 710 and Vacuumed insulation panel 400 pass through Hot melt adhesive, double-sided adhesive etc. are fixed as the 2nd bonding agent of the 2nd sandwiched component.

Here, the thickness Q of the thermal insulators 701 such as polyurethane filled between Vacuumed insulation panel 400 and interior case 750 is set It is about 15mm or more (preferably 13mm or more), it is more preferable is set as 11mm or less.In addition, in Vacuumed insulation panel 400 and interior The thickness P of the thermal insulators 701 such as the polyurethane filled between the orbit portion 755 of case 750 is set to 11mm or less (if considering not , the bumps etc. on Vacuumed insulation panel surface, then preferably less than 10mm), therefore the anti-of the thermal insulators such as polyurethane 701 can be increased Curved elasticity modulus improves the intensity of cabinet 700 or refrigerator 1.In addition, being filled out between strengthening part 731 and Vacuumed insulation panel 400 The thickness R of the thermal insulators such as the polyurethane filled 701 is set to the amount of the thickness of strengthening part smaller than predetermined thickness P, if such as plus Strong component be then 8mm or less with a thickness of 2mm, if strengthening part is with a thickness of 4mm be about 6mm hereinafter, therefore can be into one Step improves intensity.In addition, the density of the thermal insulators such as polyurethane 701 is set to be greater than 60kg/m³, therefore can be improved screw etc. The holding intensity or fixing intensity of fixation member 735 inhibit the loosening of screw, deviate or fall off.Furthermore it is possible to improve reinforcement The holding intensity or fixing intensity of component 731 inhibit the generation of the dislocation of strengthening part 731, because of screw caused by misplacing It deforms, the deformation of the orbit portion 755 of interior case 750, refrigerator, the equipment of high reliablity can be obtained.But if as sandwiched component The thermal insulators (such as hard polyurethane foams) such as polyurethane density it is excessive, then will appear following problem: (1) note of polyurethane Enter amount and increase caused increased costs, the injection pressure of (2) polyurethane increases caused polyurethane from leakages such as cabinets Occur, the box deformation inhibition mold caused by blow pressure increase, cabinet pressing component when (3) are polyurethane foam Increase Deng the clinging force with polyurethane, bonding force, and leads to box deformation inhibition mold, cabinet pressing component etc. to be difficult to from case Body falls off and (is difficult to extract from cabinet), and 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 100kg/m³Preferably (preferably 90kg/m below³Below).

In Figure 25, strengthening part 731 is made of metal or resin system, by for the plate that fixation member 735 is fixed Strengthening part body part 734, the upper end set on strengthening part body part 734 or top and stretch out in a generally horizontal direction Extension 732, the lower end set on strengthening part body part 734 or lower part and in a generally horizontal direction on the strengthening part of plate Extension 733 is constituted under the strengthening part of the plate of stretching, on strengthening part body part 734, strengthening part extension 732 plus Extension 733 is formed one (being assembled integrally) or is integrally formed under strong component.

Strengthening part 731 is adhered to the formation of orbit portion 755 in interior case 750 by the 2nd bonding agent such as double-sided adhesive, hot melt adhesive Interior case recess portion 717 710 side of outer container after, it is fixed by the thermal insulators such as filled polyurethane 701 or be held in the rail of interior case 750 Road portion 755.Strengthening part 731 is formed as on strengthening part under extension 732 and strengthening part extension 733 from strengthening part sheet The section U-shaped that the end face in body portion 734 is stretched out to the same direction, and interior case recess portion 717 is located at strengthening part body part 734 Bottom surface sections (recessed portion), on strengthening part extension 732 be configured to formed in case recess portion 717 recess portion upper section portion 718 Strengthening part 731 is set to 710 side of outer container of interior case recess portion 717 by opposite positional relationship.In addition, extension under strengthening part 733 are configured to and form the recess portion lower section portion 719 of interior case recess portion 717 in opposite directions.Strengthening part 731 can make reinforcement part as a result, Extension 733 relative to interior case 750 is easy to carry out positioning under extension 732 or strengthening part on part.Furthermore it is possible to will add Strong component 731 is mounted to cover interior case recess portion 717 from 710 side of outer container, therefore is easy to carry out the inside case 750 of strengthening part 731 Positioning or installation, in addition, the intensity of interior case recess portion 717 is also improved.Here, as long as strengthening part 731 is by strengthening part The either side of extension 733 is formed or is formed under upper extension 732 or strengthening part, it will be able to by strengthening part Extension 733 is positioned with recess portion upper section portion 718 or recess portion lower section portion 719 under extension 732 or strengthening part, because This can be omitted either side (as long as setting either side).

In addition, track support portion 820 and the lower railway 812 as trapped orbit of track component 810 pass through in Figure 25 It welds and is integrally formed, therefore be easy to carry out the assembling of the orbit portion 755 of the inside case 750 of track component 810.In addition, orbit portion Lower railway 812 of the part 810 via track support portion 820 or as trapped orbit is placed in the conduct track of interior case recess portion 717 The recess portion lower section portion 719 of component mounting portion, track component 810 is positioned in a manner of it will not move downwards, in addition, in recess portion The upper surface of lower section portion 719 side is equipped with fixed by screw etc. or keeps the fixed part of track support portion 820, to inhibit track to support Portion 820 or track component 810 are upwards or fixed part (mobile suppressing portion) is fixed or be held in the mode of lateral movement.

Track component 810 is placed in recess portion lower section portion 719 as track component mounting portion, therefore is inhibited for branch The problem of track support portion 820 of support track component 810 deforms downwards because of the weight of box body 520, so as to swimmingly Carry out the discrepancy of door or box body 520.Here, box body 520 is made of box bottom wall, four box side walls, it is top-open Container, in manufacture be equipped with pattern draft, formed box body 520 box side wall from above towards lower section, into box body 520 The inclination of mandrel direction.That is, to be formed as lower end narrower than upper end for the width of box body 520.

Therefore, the gap between box body 520 and side wall 790 (length) is that the lower end of box body 520 is bigger than upper end.As a result, when It can be with when box body 520 is supported by track component 810, when track component 810 is supported below the short transverse of box body 520 Increase the volume of box body 520, therefore preferably.By track component 810 (such as box body support portion 830) box body 520 height The width of box body can be increased when 1/2 or less preferably 1/3 support box body 520 in position below, therefore box body 520 can be increased Volume.At this point it is possible to which box body stage portion 525 is arranged in the box side wall in box body 520, by the box body support portion of track component 810 830 supporting case body stage portions 525.It is possible thereby to easily support box body 520.Furthermore, it is possible in the short transverse of box body 520 Lower end (such as the position below of 1/2 or less the height of box body 520 preferably 1/3) is supported, if but to as most lower The back side of the box bottom wall at end is supported, and just it is not necessary that box body stage portion 525 is arranged in box body 520, is easy to carry out box body 520 Manufacture.

Forming track mounting portion, that is, recess portion lower section portion 719 interior case 750 and Vacuumed insulation panel 400 (or outer container 710) Between the density of the thermal insulators 701 (such as hard polyurethane foams) such as the polyurethane filled be greater than 60kg/m³When, track component carries The intensity for setting i.e. recess portion lower section portion 719, portion is improved, therefore even if storing weight in box body 520, mounting track component 810 Track component mounting portion, that is, recess portion lower section portion 719 will not deform, can so as to steadily carry out the discrepancy of box body 520 Obtain refrigerator, the equipment of high reliablity.

In addition, in Figure 24, Tu25Zhong, interior case recess portion 717 can store at least part (such as rail of track component 810 Road support portion 820 etc.) or all, therefore can reduce overhang of the track component 810 to storeroom side, therefore, Ke Yizeng Indoor volume is stored greatly, further, it is also possible to increase the volume of box body 520.

In Figure 24, Tu25Zhong, for the outer container of interior case recess portion 717 made of being recessed from storeroom side in interior case 750 The example of 710 sides setting strengthening part 731 is illustrated, and Figure 26 is that protrusion forms from storeroom side in interior case 750 Interior case protrusion 727 710 side of outer container setting strengthening part 731 example.In figure, the interior case 750 for forming side wall 790 makes track Portion 755 is prominent to storeroom side and is formed with interior case protrusion 727.Interior case protrusion 727 has protrusion upper section portion 728, protrusion lower section Portion 729 forms convex form by protrusion upper section portion 728, protrusion lower section portion 729.

In Figure 26, interior case protrusion 727 is in the recess shapes of recess from 710 side of outer container, and being formed in, the interior case is convex Strengthening part 731 (storage at least part or whole) are accommodated in the recess portion of 710 side of outer container in portion 727, by under protrusion Section portion carries out the positioning of the up and down direction or transverse direction of strengthening part 731.In addition, by being formed in the outer of interior case protrusion 727 At least part or whole that strengthening part 731 is stored in the recess portion of 710 side of case, can reduce strengthening part 731 to outer container The overhang of 710 sides, therefore it is heat-insulated to work as filled polyurethane etc. between Vacuumed insulation panel 400 (or outer container 710) and interior case 750 When part 701, it is able to suppress the width (polyurethane between Vacuumed insulation panel 400 and strengthening part 731 for the flow path that polyurethane flows through Etc. thermal insulators 701 thickness) R narrows and polyurethane caused to be difficult to the case where flowing.Therefore, the stream of the thermal insulators such as polyurethane 701 It is dynamic to will not be blocked, thus can be by the thickness of the thermal insulators 701 such as polyurethane between strengthening part 731 and Vacuumed insulation panel 400 Degree R is set as 11mm or less (if considering unevenness, the bumps on surface of Vacuumed insulation panel etc., preferably less than 10mm), because This can substantially ensure the thickness R of the thermal insulators 701 such as polyurethane between strengthening part 731 and Vacuumed insulation panel 400, so as to Enough inhibit the fixations of tracks fixation member 735 such as reduction or the screw of the holding intensity of strengthening part 731 or keeps intensity It reduces.

In addition, trapped orbit, that is, lower railway 812 of track support portion 820 and track component 810 passes through a bodily forms such as welding At, therefore it is easy to carry out the assembling of the orbit portion 755 of the inside case 750 of track component 810.In addition, track support portion 820 is loaded Partition wall 24 or bottom surface sections 780 between being set to storeroom, and track component 810 is positioned to move downwards, this Outside, it is equipped with fixed by screw etc. in partition wall 24 or bottom surface sections 780 or keeps the fixed part of track support portion 820, and with Inhibit track support portion 820 or track component 810 upwards or fixed part is fixed or be held in the mode of lateral movement (mobile suppressing portion).Here, being equipped with Vacuumed insulation panel 400 in partition wall 24 or bottom surface sections 780.

Track component 810 is set to 710 side of outer container of the interior case recess portion 717 of interior case 750 in Figure 24, Figure 25, in Figure 26 Set on 710 side of outer container of interior case protrusion 727, but track component 810 is not necessarily to be set to interior case recess portion 717 or interior case protrusion 727, It can be set to the flat part of interior case 750 as shown in figure 27.

In Figure 27, track component 810 is set to the orbit portion 755 of interior case 750, and orbit portion 755 is by fixed parts such as screws Part 735 is fixed on the flat surface of interior case 750.In addition, the face in 710 side of outer container of orbit portion 755 is equipped with strengthening part 731, add Strong component 731 is fixed or is kept by thermal insulators 701 such as the polyurethane filled between Vacuumed insulation panel 400.At this point, plus Strong component 731 be filled in the state of by the 2nd bonding agent such as hot melt adhesive, double-sided adhesive bonding or fixed to interior case 750 every Warmware 701, thus be kept or be fixed on interior case 750 710 side of outer container face.

Same as Figure 24~Figure 26 in Figure 27, the density of the thermal insulators such as polyurethane 701 is greater than 60kg/m³, therefore screw Etc. fixation members 735 holding intensity or fixing intensity be improved, it is suppressed that the loosening of screw deviates or falls off.In addition, The holding intensity or fixing intensity of strengthening part 731 are improved, be able to suppress the dislocation of strengthening part 731 generation, because Misplace the deformation of caused screw, the deformation of the orbit portion 755 of interior case 750, can obtain refrigerator, the equipment of high reliablity.

In addition, the thermal insulators 701 such as polyurethane filled between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 Thickness P is set to 11mm or less and (if considering unevenness, the bumps on surface of Vacuumed insulation panel etc., is preferably less than 10mm), be preferably 6mm hereinafter, the Deflection Modulus of Elasticity of the thermal insulators such as polyurethane 701 therefore can be increased, improve cabinet 700 or The intensity of person's refrigerator 1.In addition, the thermal insulators 701 such as polyurethane filled between strengthening part 731 and Vacuumed insulation panel 400 Thickness R is set to the amount of the thickness of strengthening part 731 smaller than predetermined thickness P, if such as strengthening part 731 with a thickness of 2mm Then it is 8mm or less, if strengthening part 731 is with a thickness of 4mm is about 6mm hereinafter, intensity therefore can be further increased.

In addition, the end (such as lower end) of the orbit portion 755 of interior case 750 is formed with interior case 750 to storeroom in Figure 27 Side protruding portion 757 outstanding is placed with the track support portion 820 of track component 810 in the upper surface of the protruding portion 757.The protrusion Portion 757 is configured to the prominent length than track component 810 to width direction to the prominent length of the width direction of storeroom side It is small, it is prominent not into storeroom compared to track component 810, so as to inhibit the volume of reservoir volume, box body volume to become smaller.

In addition, trapped orbit, that is, lower railway 812 of track support portion 820 and track component 810 passes through a bodily forms such as welding At, therefore it is easy to for track component 810 being assembled into the orbit portion 755 of interior case 750.In addition, track support portion 820 is placed in The upper surface of the protruding portion 757 that the end (lower end) of orbit portion 755 is formed side, and track component 810 is positioned to will not be downwards It is mobile, in addition, be equipped with fixed by screw etc. in the upper surface of protruding portion 757 side or keep the fixed part of track support portion 820, and Fixation is fixed or is held in a manner of inhibiting track support portion 820 or track component 810 upwards or lateral movement Portion's (mobile suppressing portion).

Here, orbit portion 755 is located near partition wall 24 or underside wall 780, therefore rail in Figure 24, Tu26Zhong Road component 810 is installed near partition wall 24 or underside wall 780, and box body 520 is propped up in the lower position of short transverse Support, therefore the mounting intensity of track component 810 is improved, thus it is preferred that, and in Figure 25, Tu27Zhong, orbit portion 755 and separate Perhaps underside wall 780 has preset distance G to wall 24 therefore track component 810 can be relative to partition wall 24 or underside wall 780 It is installed on top with preset distance G, so as to make the Support Position of box body 520 be in top, can swimmingly carry out box body Discrepancy.Further, since the length of the box body support portion 830 of track component 810 can be shortened, therefore intensity is improved, and And obtain the track component of low cost, refrigerator.

Here, box body stage portion 525 can be arranged in the box side wall of box body 520, be supported by the box body of track component 810 830 supporting case body stage portion 525 of portion.Thereby, it is possible to easily support box body 520.Furthermore, it is possible in the height side of box body 520 To lower section or lower end (such as the position below of 1/2 or less the height of box body 520 preferably 1/3) be supported, but If being supported to the back side as the lowermost box bottom wall, just without box body 520 be arranged stage portion 525, be easy into The manufacture of row box body 520.

It is being formed as track mounting portion to storeroom side orbit portion end outstanding (orbit portion protruding portion) 757 interior The thermal insulators 701 such as the polyurethane filled between case 750 and Vacuumed insulation panel 400 (or outer container 710) (such as rigid polyurethane foam Foam) density be greater than 60kg/m³When, the intensity of the orbit portion end 757 as track component mounting portion is improved, therefore i.e. Make to store weight in box body 520, track component mounting portion, that is, orbit portion protruding portion 757 of mounting track component 810 will not become Shape, therefore the discrepancy of box body 520 can be steadily carried out, refrigerator, the equipment of high reliablity can be obtained.

Here, track component 810 can be set to side wall 790, point of the storeroom of configuration track component 810 can also be set to Next door (partition wall including the partition wall being arranged between storeroom and storeroom and the bottom surface for forming storeroom or above 24 or underside wall 780 or roof 740).I.e., it is possible to by the track support portion 820 of supporting track component 810 be set to (or It is placed in) partition wall (including partition wall 24 or roof 740 or underside wall 780).If in this way by supporting track component 810 Track support portion 820 is set to the partition wall 24 of storeroom, just it is not necessary that fixation member 735 is arranged in side wall 790, therefore can increase In the thickness of the Vacuumed insulation panel 400 of side wall configuration, furthermore, it is possible to reduce Vacuumed insulation panel 400 and interior case in side wall 790 The thickness of the thermal insulators such as the polyurethane filled between 750 701.Therefore, the indoor volume of storage or box body 520 can be increased Volume.

Here, in the case where track support portion 820 is set to partition wall, in partition wall 24 or underside wall 780 or In roof 740, it is not advisable in the position configuration Vacuumed insulation panel 400 of setting track fixation member 735.In addition, if in setting rail The position setting of road fixation member 735 is used for the strengthening part of the fixation members such as fixing screws, then the fixing intensity of fixation member Or intensity is kept to be improved.In addition, Vacuumed insulation panel 400 and formed partition wall 24 profile parts between fill or When coating or the configuration thermal insulators such as hard polyurethane foams or foam styrene, if being greater than the density of thermal insulator 701 60kg/m³, then the holding of fixed or holding track component 810 fixation member or strengthening part or fixing intensity are mentioned Height, therefore reliability improves.It should be noted that according to reason described above, the thickness of thermal insulator 701 is less than 10mm Preferably.

Above to the situation for using screw etc. fixed on the inside of storeroom the orbit portion 755 of interior case 750 (as fixation member The head of screw of 735 screw is set to the orbit portion of interior case 750 set on the threaded portion of 2,3,4,5,6 side of storeroom, fixation member 735 The case where between 755 and Vacuumed insulation panel 400) it is illustrated.But the screw 735 of fixation member can also be made from side wall 790 Laterally therein storeroom 2,3,4,5,6 in it is prominent and fixed, at this point, head of screw is set to Vacuumed insulation panel 400 and interior case 750 Between orbit portion 755 (orbit portion 755 or the thermal insulators 701 such as track strengthening part 731 or polyurethane are fixed in threaded portion), but Even if in this case, since the density of polyurethane is greater than 60kg/m³, therefore the intensity of the thermal insulators such as polyurethane 701 increases, spiral shell The fixing intensity of the thermal insulators 701 such as the thermal insulators such as fixation members 735 and polyurethane 701, interior case 750 and the polyurethane such as nail or guarantor Box body 520 can be made so that the deformation of interior case etc., the dislocation of strengthening part 731, loosening of screw etc. are suppressed by holding intensity increase Deng swimmingly pull-out (can swimmingly enter and leave).

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

In addition, by the way that the thickness of foaming heat insulation part/(thickness+Vacuumed insulation panel thickness of foaming heat insulation part) is set as 0.3 hereinafter, can reduce the composite guide heating rate for the composite component for being composed foaming heat insulation part and Vacuumed insulation panel, therefore be Make thinned wall thickness that heat-proof quality also can be improved.

In addition, by making the density after polyurethane foam be greater than 60kg/m³, can be thinned while maintaining the intensity of wall Wall thickness.

As above, in embodiments of the present invention, in the opposite position in the position of the setting track component with side wall 790 Foaming heat insulation part (such as hard polyurethane foams) between interior case 750 and Vacuumed insulation panel 400 it is (excellent with a thickness of 11mm or less Choosing be less than 10mm), by the thickness of foaming heat insulation part/(thickness+Vacuumed insulation panel thickness of foaming heat insulation part) be set as 0.3 with Under, and the density after polyurethane foam is made to be greater than 60kg/m³When, wall can further be thinned while maintaining the intensity of wall It is thick.It, therefore, can be with as the thickness of foaming heat insulation part here, the thickness with a thickness of polyurethane of the foaming heat insulation part in above formula Be the thickness P of thermal insulators 701 such as the polyurethane filled between Vacuumed insulation panel 400 and the orbit portion 755 of interior case 750 or The thickness Q or Vacuumed insulation panel 400 of the thermal insulators 701 such as the polyurethane filled between Vacuumed insulation panel 400 and interior case 750 The thickness R of the thermal insulators such as the polyurethane between strengthening part 731 701.For example, make foaming heat insulation part with a thickness of vacuum heat-insulation When the thickness R of the thermal insulators such as the polyurethane between part 400 and strengthening part 731 701, by the thickness R/ (foaming of foaming heat insulation part The thickness of the thickness R+ Vacuumed insulation panel of thermal insulator) it is set as 0.3 or less.Equally, when making with a thickness of P Q, by thickness R is replaced as P or Q.In addition, the thickness of polyurethane shown in Figure 17, Figure 18, Figure 19 is equally also possible in Vacuumed insulation panel The thickness P of the thermal insulators such as the polyurethane filled between 400 and the orbit portion 755 of interior case 750 701, in Vacuumed insulation panel 400 and interior Poly- ammonia between the thickness Q of the thermal insulators such as the polyurethane filled between case 750 701, Vacuumed insulation panel 400 and strengthening part 731 The thickness R of the thermal insulators such as ester 701.

Further, since including cabinet, formed by outer container 750 and interior case 710, there is back face wall 730, side wall 790；Cabinet The interior storeroom 2,3,4,5,6 for dividing by partition wall 24 and formed and had in front opening portion；It is accommodated in storeroom, via setting It is placed in the box body of the drawer type of the pull-out of track component 810 of the side wall of storeroom；Vacuumed insulation panel 400, core material is by inorfil Or the fiber-like material that organic fiber is constituted is formed, and is configured at and is used to form between the interior case of side wall and outer container, the side wall It is provided with track component 810；It is set to inner box side between the interior case of the position opposite with track component and Vacuumed insulation panel simultaneously For supporting or keeping the strengthening part 731 of track component；And it is filled in the strengthening part of the position opposite with track component Thermal insulator 701 between Vacuumed insulation panel；The thickness of the thermal insulator of opposite position is less than 10mm and track with track component The density of the thermal insulator being filled between interior case and Vacuumed insulation panel in portion is greater than 60kg/m³, then can be in the intensity for maintaining wall While be thinned wall thickness, can also be improved heat-proof quality.But if the thermal insulators such as polyurethane as sandwiched component (such as it is hard Matter polyurethane foam) density it is excessive, then will appear following problem: (1) polyurethane injection rate increase caused by cost increase Add, the injection pressure of (2) polyurethane increases caused polyurethane from the generation of the leakages such as cabinet, and (3) are due to polyurethane foam When blow pressure increase caused by box deformation inhibition mold, cabinet pressing component etc. and polyurethane clinging force, viscous Relay 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 addition, wall thickness can further be thinned if making the Deflection Modulus of Elasticity 20MPa or more of Vacuumed insulation panel 400.? This, can not be fixed to side wall 790 for track component, and be secured to point of the underside wall 780 near side wall 790 or bottom surface Next door 24 or upper wall (roof) 740 or partition wall 24 above.Here, at the position with the setting fixation members such as screw When Vacuumed insulation panel 400 is not configured between opposite interior case 750 and outer container 710, be arranged fixation member underside wall 780 or under The partition wall 24 or roof 740 in face or partition wall 24 above are preferably the wall or partition wall not contacted with outer gas.? The wall (such as side wall 790, roof 740, back face wall 730, underside wall 780 etc.) contacted with outer gas reduce to the greatest extent be not provided with vacuum every If the position of warmware 400, loss caused by capable of reducing because of heat leak, therefore high performance heat insulating box, ice can be obtained Case, equipment.Thereby, it is possible to increase the configuration area of the Vacuumed insulation panel 400 of back face wall 730, side wall 790, therefore it is capable of increasing The covering rate or filling rate of Vacuumed insulation panel 400 in heat insulating box 700.

Here, the heat insulating box 700 of present embodiment 1, mainly undertakes with the hard polyurethane foams in heat insulating box 700 This prior art of heat insulating function thought is different, based on making Vacuumed insulation panel 400 in the part configured with Vacuumed insulation panel 400 Undertake heat-proof quality and cabinet intensity this new technical idea.Therefore, the heat insulating box 700 of present embodiment 1 makes outside The filling rate of Vacuumed insulation panel 400 in the wall formed between case 710 and interior case 750 in space 315 be (Vacuumed insulation panel 400 Ratio shared by total volume of the volume relative to space 315 in the wall formed between outer container 710 and interior case 750) it is predetermined value (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.

(other compositions of the 1st wind path accessory)

In addition, if reaching the width direction length of the 1st wind path accessory 762 of a part to form cold air wind path 760 The inner face of side wall 790 also covers at least part or whole of recess portion 440, protrusion 450 to not only covering second recesses 441, Then the 1st wind path accessory 762 can be also used as the Appearance Panel, can cover the back face wall 730 or side wall of room (such as storeroom) Perhaps whole can be by the 1st wind path accessory 762 as the covering back side or one of side at least part of 790 inner face The cover member divided uses.Therefore, the supply mouth of the cold air to indoor supply from cold air wind path 760 is being matched set on the 1st wind path When part 762, the freedom degree of configuration can be improved, efficiently cool down indoor storage item, in addition, the 1st wind path accessory 762 can make With another component different from interior case 750, thus can easily change shape or color or carry out various processing, coating or Literature record etc., functional, aesthetic appearance are improved.1st wind path accessory is also used as the Appearance Panel and is used as cover member When, it is shaped generally as U-shaped and covers at least part or wall of the back face wall 730 of forming chamber and the inner face of side wall 790 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 Deflection Modulus of Elasticity (MPa) of urethane foam.In Figure 17, horizontal axis indicates the flow path thickness (mm) of filling hard polyurethane foams, The 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.

It (1) the use of total plate thickness of outer container 710 and interior case 750 is about 2mm or less, the plate thickness including outer container 710 and interior case The average wall thickness of the heat insulating box 700 of 750 plate thickness is about 20mm or more about 40mm heat insulating box below (here, preferably including Wall thickness including the plate thickness of back face wall 730, side wall 790, roof 740, underside wall 780, partition wall 24 etc. be about 20mm or more about 40mm is hereinafter, in addition, eliminate the average distance in the wall thickness direction in the space 315 of the plate thickness of outer container 710 and interior case 750 (in wall Thickness) be about 18mm~about 38mm).

(2) Vacuumed insulation panel 400 with a thickness of about 10mm~about 30mm, part configured with Vacuumed insulation panel is (such as recessed Portion 440 or second recesses 441) wall in space 315 in hard polyurethane foams wall thickness direction mean flowpath width (polyurethane flow path thickness) is 1mm or more (preferably 3mm or more), 11mm or less is (if consider uneven, Vacuumed insulation panel 400 The bumps etc. on surface, then be advisable, preferably 6mm or less less than 10mm).

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

(4) thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (mK)~0.0025W/ (mK).

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

The heat-proof quality of this refrigerator 1 passes through the filling rate for being set to make Vacuumed insulation panel 400 and covering rate is in predetermined In the range of and select the size of Vacuumed insulation panel 400, thickness, make Vacuumed insulation panel 400 relative to the thermal insulation of heat insulating box Can, the cabinet intensity of heat insulating box become overriding, thus when the thermal conductivity of Vacuumed insulation panel 400 is smaller, can reduce every The composite guide heating rate of hot tank body is to which preferably, preferably 0.0030W/ (mK) is below.If the thermal conductivity of Vacuumed insulation panel 400 is super 0.0030W/mK is crossed, then the influence that wall thickness reduces to heat-proof quality becomes larger, and heat-proof quality deteriorates, and power consumption increases.Therefore, In the present embodiment, by making the thermal conductivity 0.0030W/ (mK) of Vacuumed insulation panel 400 hereinafter, being able to suppress and being thinned The influence that the opposite heat-proof quality of wall thickness reduces.In addition, the thermal conductivity of Vacuumed insulation panel 400 is the smaller the better, but in order to will be thermally conductive Rate reduces cost spent by 0.001W/ (mK) and substantially increases, therefore is using the thermal conductivity of Vacuumed insulation panel 400 The component of 0.0012W/ (mK) or more.If the thermal conductivity of Vacuumed insulation panel 400 is 0.0019W/ (mK) above 0.0025W/ (mK) hereinafter, it is about 10 times just smaller than the thermal conductivity of hard polyurethane foams, therefore the heat-proof quality of heat insulating box 700 is compared The prior art is especially good, can satisfy product specification.Therefore, Vacuumed insulation panel 400 is about 0.0012W/ (m using thermal conductivity K) the component of the above 0.0030W/ (mK) (preferably from about 0.0019W/ (mK) the above 0.0025W/ (mK) is below) below ?.

An example of heat insulating box 700 as embodiments of the present invention, is shown in table 1 wall thickness and Vacuumed insulation panel The relationship of the box deformation amount of 400 filling rate, the Deflection Modulus of Elasticity of hard polyurethane foams, heat insulating box 700.Table 1 1 is existing specification, be wall thickness be 40mm, the filling rate of Vacuumed insulation panel 400 is 20%, in interior case 750 and vacuum heat-insulation The result when Deflection Modulus of Elasticity for the polyurethane filled between part 400 is 9MPa.Here, the bending resistance bullet of Vacuumed insulation panel 400 Property modulus use 20MPa component.According to the item 1 and item 2 of table 1, the filling rate of Vacuumed insulation panel 400 is 20%, polyurethane When Deflection Modulus of Elasticity is 9MPa, if the wall thickness of heat insulating box 700 is made to be thinned to 30mm, cabinet strength reduction from 40mm.Cause This, as shown in item 3 it is found that in the case where making wall thickness reduction to 30mm, if increasing to the filling rate of Vacuumed insulation panel 400 40% or more, although then box deformation amount is more slightly larger than item 1 (prior art), it is reduced to same with item 1 (prior art) Degree.

As shown in the item 4 of table 1, even if the wall thickness of heat insulating box 700 is thinned to from existing 40mm (item 1 of table 1) 30mm, as long as 40% or more the filling rate of Vacuumed insulation panel 400 and the Deflection Modulus of Elasticity of polyurethane is made to be 15Mpa or more (item 4 of table 1), so that it may so that box deformation amount is smaller than the prior art (item 1), therefore the cabinet of heat insulating box 700 can be made strong Degree is existing component (item 1) or more.That is, even if wall thickness (such as being reduced to 30mm from 40mm) is reduced, as long as by Vacuumed insulation panel 400 filling rate and the Deflection Modulus of Elasticity of polyurethane are set as predetermined value or more, so that it may improve with not reducing cabinet intensity Heat-proof quality.Therefore, in the present embodiment, by using Deflection Modulus of Elasticity 20MPa or more as Vacuumed insulation panel 400 Component, and the filling rate of Vacuumed insulation panel 400 is set as 40% or more, sets the Deflection Modulus of Elasticity of hard polyurethane foams It is set to 15MPa or more, it, can also be compared with prior art even if the wall thickness (such as being thinned to 30mm from 40mm) of heat insulating box is thinned Improve the intensity of heat insulating box 700.

In addition, forming the outsourcing material (exterior film) of the profile of Vacuumed insulation panel 400, compared to aluminium foil film, it is preferable to use aluminium steamings Plated film.For heat leak (the hot outsourcing via Vacuumed insulation panel 400 for inhibiting the outsourcing material along Vacuumed insulation panel 400 to occur The so-called heat bridge that material is rearwardly conducted and leaked from the surface of Vacuumed insulation panel 400), the outsourcing as Vacuumed insulation panel 400 Material compares aluminium foil film, preferably uses the aluminium-vapour deposition film for being difficult to generate heat bridge as outsourcing material (exterior film).

In addition, the measurement of the Deflection Modulus of Elasticity of the hard polyurethane foams in present embodiment 1, thermal conductivity, density, example Such as measured by cutting the hard polyurethane foams of predefined size (such as 100 × 100 × 5mm or more).It is being configured with The part of Vacuumed insulation panel 400, from each face in left and right side, the back side, top surface, this five faces of bottom surface configured with Vacuumed insulation panel Part cuts multiple, calculates its average value.(when only cutting 1 position, it is next alternative that many places measurement etc. is carried out at 1 position It is advisable).When door is also configured with Vacuumed insulation panel, density, Deflection Modulus of Elasticity, the thermal conductivity for also measuring polyurethane on the door are It can.In addition, in the part that Vacuumed insulation panel 400 is not configured, also to left and right side, the back side, top surface, this five faces of bottom surface each face It cuts multiple, and calculates its average value.In the present embodiment, be in any case from can speculate density or The biggish place of Deflection Modulus of Elasticity is cut and is measured.In addition, there are the wirings of refrigerant piping 725, lead etc. to match In the case where hard polyurethane foams cannot being cut into predefined size whens part 720 is equal etc., using close to the position of center as The position that the hard polyurethane foams of predefined size can be cut is advisable.

In the present embodiment, to each face in this six faces of left side, right side, the back side, top surface, bottom surface or door, The density or Deflection Modulus of Elasticity of the polyurethane of part and the part that is not configured of the measurement configured with Vacuumed insulation panel 400, make The density or Deflection Modulus of Elasticity of polyurethane are predetermined value or more.It can be by adjusting the free foaming density, true of polyurethane Thickness, wall thickness of empty thermal insulator etc., will be between Vacuumed insulation panel 400 and interior case 750 or Vacuumed insulation panel 400 and outer container The density of the polyurethane of sandwiched or Deflection Modulus of Elasticity are set as predetermined between 710 or between outer container 710 and interior case 750 It is more than value.

Here, in the present embodiment, in this six faces of left and right side, the back side, top surface, bottom surface or door, for each face The density of the polyurethane of the part configured with Vacuumed insulation panel 400, Deflection Modulus of Elasticity are at least set as predetermined value or more, this Each face at least can also be set the density for the polyurethane that the part of Vacuumed insulation panel 400 is not configured, Deflection Modulus of Elasticity outside It is set to predetermined value or more.Here, in this six faces of left and right side, the back side, top surface, bottom surface or door, if being set to for each face Make polyurethane density, more than Deflection Modulus of Elasticity predetermined value, then in the part that Vacuumed insulation panel 400 is not configured, intensity is also mentioned It is high.Further, since intensity can be obtained in each individual face, therefore can be only by the section sets of needs at high intensity, energy It is enough to obtain low cost and the heat insulating box of high reliablity, refrigerator, equipment.In addition, being set to make left and right side, the back side, top surface, bottom The density in this six faces of face or door or the average value of Deflection Modulus of Elasticity are the 1st predetermined value or more (density 60kg/m³With Upper, Deflection Modulus of Elasticity 15MPa or more) and the 2nd predetermined value below (density 100kg/m³Below, Deflection Modulus of Elasticity 150MPa When below), it can be ensured that the intensity of entire cabinet, therefore heat-proof quality height, the heat insulating box of high reliablity, ice can be obtained Case, equipment.

In addition, covering rate, filling rate for Vacuumed insulation panel 400, also left and right side, the back side, top surface, bottom surface or This six faces of door are set to the covering rate made in each face or multiple faces altogether, more than filling rate predetermined value, then due to every A individual face can obtain intensity, heat-proof quality, therefore can obtain low only by the section sets of needs at high intensity Cost, high heat-insulated, high reliablity heat insulating box, refrigerator, equipment.In addition, being set to make left and right side, the back side, top surface, bottom surface Or when more than door this six faces generally predetermined value, it can be ensured that the intensity of entire cabinet, the thermal insulation for improving entire cabinet Can, therefore heat-proof quality height, the heat insulating box of high reliablity, refrigerator, equipment can be obtained.

More than, in the heat insulating box 700 of present embodiment, the covering rate of Vacuumed insulation panel 400 is made to be greater than predetermined value (60%) (70% or more the laterodorsal covering rate for making Vacuumed insulation panel 400).In addition, making the filling of Vacuumed insulation panel 400 Rate is also predetermined value (40%) or more to reduce the loading of hard polyurethane foams, therefore can ensure the heat-insulated of heat insulating box Performance and cabinet intensity, at the same can make heat insulating box 700 the wall ratio prior art it is thin.Therefore, heat-proof quality is mentioned Height can make to store the amount that indoor internal volume increases wall thickness reduction compared with prior art to energy conservation, so as to mention For the heat insulating box 700, refrigerator 1, showcase, equipment of internal volume good efficiency.That is, embodiment according to the present invention, constant The outer dimension of more heat insulating box 700 or the equipment such as refrigerator 1 or showcase can increase internal volume (example compared with prior art Such as the internal volume of storeroom 2~6), therefore the comparable prior art increases heat insulating box 700 or the inside of refrigerator 1 and can store Storage item.Thereby, it is possible to obtain the equipment such as user convenient to use, energy-efficient heat insulating box 700, refrigerator 1, showcase.Conversely, If keeping internal volume (such as internal volume of storeroom 2~6) same with the prior art, outer dimension can be reduced, therefore can obtain Obtain the equipment such as energy saving and compact heat insulating box 700, refrigerator 1, showcase, hot-water supply.

In addition, heat insulating box 700, the mode of refrigerator 1 shown in present embodiment, shape only an example.For example, The reserve storage space of heat insulating box 700 can be divided with 3 cross septation plates and form four storages skies in above-below direction Between (storeroom).In addition, the 3 cross septation plate divisions of the reserve storage space of heat insulating box 700 can also for example be gone forward side by side One step is divided with vertical demarcation plate, to form five storage spaces (storeroom).It, can be into one by increasing the quantity of demarcation plate Step improves the intensity of heat insulating box 700.That is, increasing the quantity of demarcation plate to increase the quantity of receiving room, storeroom, The effect that cabinet intensity is improved by demarcation plate can be obtained, so that even if the part covered by Vacuumed insulation panel 400 is thinned The average thickness of hard polyurethane foams (space 315 between Vacuumed insulation panel 400 and interior case 750) is (such as 11mm or less, excellent Choosing is less than 10mm, more preferably 6mm or less), enough cabinet intensity is also ensured.Therefore, heat insulating box 700 is not changed Outer dimension can further increase the internal volume of storeroom, and the inside that can further increase heat insulating box 700 can store Storage item.

In addition, in the present embodiment, about the internal structure of partition wall 24, can be same as heat insulating box 700 It constitutes.That is, configuring Vacuumed insulation panel 400 in the inner space of partition wall 24 and filling hard polyurethane foams, but hard polyurethane As long as ester foam is used as bonding agent, therefore can be relatively thin, such as can be about 11mm or less (if considering uneven, vacuum The bumps etc. on the surface of thermal insulator, then for less than 10mm), even more preferably about 6mm or less.Here, in partition wall 24 not such as The situation that heat insulating box 700 configures piping 725, wiring 720 etc. like that is more, therefore in this case, although can also incite somebody to action Vacuumed insulation panel 400 relative to the filling rate of partition wall 24 be set as same with heat insulating box 700 40% or more 90% hereinafter, But about partition wall 24, vacuum heat-insulation can be configured in the substantially entire surface of the size (space in partition wall 24) of partition wall 24 Part 400, therefore the filling rate of Vacuumed insulation panel 400 can be increased to about 40% or more 95% or less.In addition, hard polyaminoester The Deflection Modulus of Elasticity of foam is 15MPa or more, density is greater than 60kg/m³It is advisable.It is also configured in demarcation plate 24 in this way Filling rate is simultaneously set in preset range by Vacuumed insulation panel 400, can be further improved the heat-proof quality of heat insulating box 700.

In the present embodiment, in the case where the heat insulating box or thermal wall for having Vacuumed insulation panel, consider assembling Property and Vacuumed insulation panel 400 is adhered directly by 2nd bonding agent different from polyurathamc such as hot melt adhesive, double-sided adhesive outer Case 710, as to be bonded bonding agent filling hard polyaminoester as the main purpose between Vacuumed insulation panel 400 and interior case 750 Foam；But the isolation formed by resins such as EPS can also be configured in the space 315 being formed between outer container 710 and interior case 750 Object etc. and Vacuumed insulation panel 400 is floated on and is configured between interior case 750 and outer container 710, and in Vacuumed insulation panel 400 and outer container Hard polyurethane foams are filled between 710 and between Vacuumed insulation panel 400 and interior case 750.In addition it is also possible to by vacuum heat-insulation Part 400 by the 2nd bonding agent such as hot melt adhesive, double-sided adhesive is adhered directly onto interior case 750 and in Vacuumed insulation panel 400 and outer container 710 Between filled polyurethane foam.

Here, when floating on Vacuumed insulation panel 400 by spacer etc. to be configured between outer container 710 and interior case 750, It can be in the inner face side (space between outer container 710 and Vacuumed insulation panel 400) of outer container 710 setting spacer and in spacer sky Between refrigerant piping 725 (such as condensation piping) is set.Refrigerant piping 725 is also to make from the compression being configured in the 1A of Machine Room The condensation piping of the refrigerant flowing for the high temperature and pressure that machine 12 is discharged, is leading via the tube wall and outer container 710 of refrigerant piping 725 Under the action of heat etc., keeps the refrigerant flowed in piping 725 cooling by the air around piping 725 and keep refrigerant cold It is solidifying, to be used as condensation piping.In addition, the heat insulating box 700 of present embodiment is nonoverlapping with refrigerant piping 725 The inner wall setting of the outer container 710 of position (not opposite position) has the resin of the thickness of the diameter of refrigerant piping 725 or more The spacer of system, and Vacuumed insulation panel 400 is made to paste spacer, so, make refrigerant piping 725 close to outer container 710 Ground with postponing, can by the spacer for being pasted with Vacuumed insulation panel 400 in a manner of covering refrigerant piping 725 with double-sided adhesive etc. It is adhered directly onto outer container 710, it is easily fabricated.Vacuumed insulation panel 400 is configured to and interior case by the heat insulating box 700 of present embodiment 750 at predetermined spaced intervals, and Vacuumed insulation panel 400 is configured to outer container 710 at predetermined spaced intervals, therefore becomes vacuum Thermal insulator 400 is embedded in the composition in hard polyurethane foams, and heat-proof quality is improved.

As described above, in the present embodiment, heat insulating box 700 can space between outer container 710 and interior case 750 It is foam filled so that Vacuumed insulation panel 400 is embedded in hard polyurethane foams, in this case in outer container 710 and vacuum in 315 The case where there is condensation piping 725 between thermal insulator 400 is more, but can be by being configured to the isolation using resins such as EPS Object etc. makes Vacuumed insulation panel 400 and outer container 710 have scheduled distance, to configure Vacuumed insulation panel 400.

In addition, Vacuumed insulation panel 400 when becoming high temperature, is easy to absorb the gas of surrounding, internal vacuum degree will lead to It reduces, thermal conductivity deteriorates.In the case where the outside air temperatures such as summer height, the ambient temperature (air themperature of surrounding) of outer container 710 It getting higher, the temperature of outer container 710 itself may also be got higher, in addition, also become high temperature as the piping 725 that condensation piping uses, because This preferably makes Vacuumed insulation panel 400 far from outer container 710, refrigerant piping from the angle for the reliability for ensuring Vacuumed insulation panel 400 (condensation piping) 725.By making Vacuumed insulation panel 400 far from outer container 710, refrigerant piping (condensation piping) 725, can inhibit Vacuumed insulation panel 400 is deteriorated because caused by rising temperature, if therefore floating Vacuumed insulation panel 400 with remote by spacer etc. Wall surface or refrigerant piping 725 from outer container 710, so that it may inhibit the reduction of heat-proof quality, long-term reliability can be provided High heat insulating box 700, refrigerator 1.

In addition, Vacuumed insulation panel 400 sometimes gas (air etc.) around absorb due to cause internal vacuum degree decline, Thermal conductivity deteriorates, but by being configured to the spacer of the resins such as EPS pasting the ground such as outer container 710 in hard polyurethane foams Interior embedded Vacuumed insulation panel 400, it is possible to reduce the amount of the gas (air etc.) around Vacuumed insulation panel 400, therefore can To inhibit Vacuumed insulation panel 400 to absorb the gas (air etc.) of surrounding, vacuum caused by the reduction because of vacuum degree can be inhibited The deterioration of thermal insulator 400 can maintain high heat-proof quality for a long time, and can provide heat insulating box 700, the refrigerator of high reliablity 1, equipment etc..

Especially, in the heat insulating box of present embodiment 700, hard polyurethane foams are existing heat-insulated using density ratio Hard polyurethane foams used in cabinet it is high (density be greater than 60Kg/m³), therefore the bubble in hard polyurethane foams The amount that density increases can correspondingly be reduced, it is possible to reduce the amount (air capacity) of the gas in bubble.Therefore, so that Vacuumed insulation panel When being filled or configured in a manner of embedded or covering by hard polyurethane foams around 400, it is possible to reduce vacuum The amount of gas (air etc.) around thermal insulator 400, therefore the reduction of the vacuum degree of Vacuumed insulation panel 400 can be inhibited (density of polyurethane is bigger, and the gap number in polyurethane is fewer, and the air capacity in polyurethane is fewer).Especially in polyurethane When thinner thickness (when for example, 11mm or less), Vacuumed insulation panel 400 is easy to make the gases such as equal air around polyurethane Into, therefore increase the density of polyurethane to reduce the gas flow around Vacuumed insulation panel 400 for Vacuumed insulation panel 400 The effect of degradation inhibiting is larger.Therefore, the deterioration of Vacuumed insulation panel 400 can be further suppressed, long-term reliability can be provided High heat insulating box 700, refrigerator 1, equipment.

In addition, in the present embodiment for it will condense 725 heat insulating box 700 that is configured in space 315 of piping into Go explanation, but can certainly be in hard in the heat insulating box 700 that condensation piping 725 is not configured in space 315 Vacuumed insulation panel 400 is buried in polyurethane foam.The amount of the gas around Vacuumed insulation panel 400 can be reduced, therefore It can inhibit the deterioration of Vacuumed insulation panel 400, can provide long-term reliability high heat insulating box 700.

Here, in the not formed orbit portion of interior case 750 (track or recess portion of the drawer of drawer type storeroom etc.) 755 The case where heat insulating box 700 of composition, refrigerator 1 etc., interior case 750 are to be easy to directly paste vacuum using bonding agent, double-sided adhesive etc. When the shape of thermal insulator 400, all or part of of Vacuumed insulation panel 400 can also be configured at interior 750 side of case.

Here, as shown in the embodiment in being adhered directly onto Vacuumed insulation panel 400 by hot melt adhesive, double-sided adhesive etc. In the case where the heat insulating box 700 of the composition of 750 side of case, energy conservation can be provided with lesser amount of Vacuumed insulation panel 400 and stored The internal volume efficiency of the room heat insulating box 700 better than the prior art, refrigerator 1.That is, substantially rectangular parallelepiped or cylindrical shape every In the case where hot tank body 700, the surface area of case 750 is big in the surface area ratio of outer container 710, therefore is pasting Vacuumed insulation panel 400 When, the Vacuumed insulation panel 400 for being sticked to interior 750 surface of case is fewer than the Vacuumed insulation panel 400 for being sticked to 710 surface of outer container, therefore can Obtain inexpensive and good heat-proof quality heat insulating box, refrigerator, showcase, hot water supply device, equipment.In addition, for example pasting phase With size Vacuumed insulation panel 400 when, in corner (such as the back as heat insulating box 700 of the heat insulating box 700 of rectangular-shape The corner or top surface of the interconnecting piece in face and side and the corner of side or top surface and the corner at the back side etc.), corner portion that Between the Vacuumed insulation panel 400 of this adjacent wall surface gap (such as top surface Vacuumed insulation panel 400 and adjacent side vacuum Gap or distance between thermal insulator 400), when Vacuumed insulation panel 400 is configured at 710 side of outer container, than by vacuum heat-insulation Part 400 is configured at big when interior 750 side of case.That is, by the way that Vacuumed insulation panel 400 is configured at interior case 750, and by the true of same size Empty thermal insulator 400 is compared when being configured at outer container 710, can be reduced between being formed between adjacent Vacuumed insulation panel 400 Gap, heat waste caused by making because of heat leak correspondingly reduce the amount of gap shrinks, are capable of providing the good heat insulating box of heat-insulating efficiency 700, refrigerator 1, hot water supply device, showcase, equipment.

In addition, the heat insulating box 700 of present embodiment has for being formed in equal divide of inner utilization partition wall 24 Multiple storerooms 2,3,4,5,6 the shutter door of radial type or drawer type that is opened and closed of opening portion.The door has by example The profile parts (outside plate) constituted such as metal and the inner part (inner panel) being made of such as resin.Also, it is being formed in profile (filling) is configured in door inner space between component and inner part hard polyurethane foams and Vacuumed insulation panel 400.Door It is also based on following technical idea illustrated by present embodiment and is formed: by Vacuumed insulation panel filling out relative to heat insulating box The rate of filling is set in preset range and ensures the overwhelming majority of heat insulating function by Vacuumed insulation panel 400.Make the vacuum of an inner space The filling rate of thermal insulator 400 is 40%~90%, covering rate is 70% or more.

When manufacturing this shutter door, Vacuumed insulation panel 400 is first passed through into the 2nd bonding agent etc. in advance and is adhesively fixed to profile portion The raw material of liquid hard polyurethane foams is injected the space between Vacuumed insulation panel and inner part, outer part by part Space between inner part, in a manner of enabling profile parts, Vacuumed insulation panel 400, inner part to be integrally formed into Row foaming, so as to hard polyurethane foams of the filling as foaming heat insulation part in door inner space.At this point, hard polyurethane It can be 1mm or more preferably 3mm or more and 11mm as long as the thickness of ester foam is also with the intensity as bonding agent (preferably smaller than 10mm, more preferable 6mm or less) below.

In addition, existing for shutter door and being used to support containing box (storage box body 520) in the installation of storeroom 2,3,4,5,6 Frame or door storage portion or shelf 80 etc. situation, thus in the presence of needing the fixing screws of frame, door storage portion Fixation member, shelf 80 installing component etc. using the secure components such as screw, fixation member, holding member and fasten or keep To shutter door inside (case on the inside of) the case where.In this case, there are secure component, fixation member, holding members into door The prominent situation in portion space, if being contacted with Vacuumed insulation panel 400, it is possible to the outsourcing material of Vacuumed insulation panel can be damaged, therefore It is preferred that thickness configuration or the filled polyurethane foam of Vacuumed insulation panel 400 will not be damaged in the inside of shutter door.However, simultaneously Especially do not need to be installed on installation fitting (such as secure component, fixation member, the guarantor of (inboard side) on the inside of the storeroom of shutter door Hold component etc.) when, Vacuumed insulation panel 400 can also be pasted into inner panel.In addition, avoiding installation fitting setting Vacuumed insulation panel When, Vacuumed insulation panel can also be pasted into inner panel.

In addition, with profile parts (outside plate) and inner part (inner panel), be formed in profile parts and inner part Between door inner space configuration Vacuumed insulation panel 400, fill out between profile parts or inner part and Vacuumed insulation panel 400 In the case where useing the hard polyurethane foams for foaming heat insulation part as, if the density of foaming heat insulation part is made to be greater than 60kg/m³, then right It is used to support the holding intensity or fixed strong of fixation member i.e. screw that the frame of containing box (storage box body 520) is fixed etc. Degree is improved, therefore even if storing weight in box body 520, door is also difficult to deform, and can steadily carry out going out for box body 520 Enter, refrigerator, the equipment of high reliablity can be obtained.In addition, for fixing fixation member i.e. screw of the other components such as handle etc. Holding intensity or fixing intensity be improved, therefore the doors installing component such as handle of other component will be used as to be installed on door When, door installing component is improved to the installation strength of door, therefore door is difficult to deform, and can steadily carry out the opening and closing of door, energy Enough obtain refrigerator, the equipment of high reliablity.If in addition, making between profile parts or inner part and Vacuumed insulation panel 400 Hard polyurethane foams as foaming heat insulation part are greater than 60kg/m³, then the Deflection Modulus of Elasticity of foaming heat insulation part is improved, The intensity of door is also improved.

Here, Vacuumed insulation panel 400 can be configured at all shutter door or a part of shutter door.For example, in outer gas and When temperature difference in heat insulating box 700 (such as in storeroom) is smaller (such as the refrigerating temperature zones such as refrigerating chamber 2, vegetable compartment 5 Storeroom), even if Vacuumed insulation panel 400 is configured at shutter door, the effect that heat-proof quality improves is also smaller.In this case, Even if Vacuumed insulation panel 400 is not configured to shutter door can also ensure that sufficient heat-proof quality.Vacuumed insulation panel 400 is in outer gas When bigger with 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 24,60% or more the filling rate of Vacuumed insulation panel 400 can be made (to make the side back face covering rate 70% of Vacuumed insulation panel 400 More than), and make other wall surfaces, partition wall 24 Vacuumed insulation panel 400 40% or more filling rate (90% or less).It is logical Composition in this way is crossed, heat can be inhibited to invade from the high Machine Room 1A of temperature, control base board room to neighbouring storeroom, ice can be made The more energy-saving of case 1.

The heat insulating box 700 of present embodiment for example can be used for heating the heating device of water and have storage and stay and added by this The heat accumulation water installations of the tank of the warmed-up water of thermal.By the inside batch tank in heat insulating box 700, shape ruler can be passed through It is very little than existing small heat insulating box 700 that tank is more heat-insulated, water storage device space saving can be made.As long as in addition, present embodiment Be with the thermal wall with Vacuumed insulation panel equipment (such as refrigerator, showcase, refrigerator, hot-water supply, hot shot water machine, Air-conditioning device etc.) it can apply.
